Historically HIV positive patients were considered a contraindication for renal transplant. After the year 1996, with the introduction of HAART the retropositive patients live longer and therefore end stage organ disease is now an increasingly important cause of mortality and morbidity in these patients. Here we report our experience for the first time in India. A forty nine year old hypertensive female from Africa who was diagnosed chronic kidney disease and retropositive status, progressed to end stage renal disease and underwent live related renal transplant at our centre.

To describe and compare the predominant bacterial and fungal species associated with gingivitis, periodontitis, and linear gingival erythema (LGE), in HIV positive subjects with different immune status. Viral loads and CD4 levels determined HIV disease status. From pooled subgingival plaque, 16S and 18S rDNA were cloned and sequenced to determine species identity. One hundred and nine bacterial species were identified from 14 subjects. Nearly half of the species were not cultivable. Notably, the classical putative periodontal pathogens, Treponema denticola, Porphyromonas gingivalis and Tannerella forsythia were below the limit of detection and were not detected. Species of Gemella, Dialister, Streptococcus and Veillonella were predominant. In one HIV positive subject with periodontitis and low viral load, Gemella morbillorum, a known opportunistic pathogen, constituted 84% of the clones. Saccharomyces cerevisiae was the only fungal species detected in an LGE subject and in periodontitis subjects with high viral loads. In periodontitis patients with low viral loads, Candida albicans was predominant, while S. cerevisiae was only a minor component. These case studies suggest that other bacterial species, rather than the classical periodontal pathogens, may be involved in periodontal diseases of subjects with HIV. These data are indicative of opportunistic infections in a highly susceptible immunocompromised host.
Abstract. Background: A HIV positive-to-positive program was started in South Africa in 2008. The program was started because dialysis is not freely available to everyone, but severely limited and only available to a selected group of patients. Patients and Methods: Between September 2008 and March 2015, 29 patients were transplanted from HIV-positive brain-dead donors at Groote Schuur Hospital transplant team. Donors were either naïve to anti-retroviral therapy or on first line therapy. The recipients were selected to have undetectable plasma HIV type 1 RNA levels and be on a stable antiretroviral regimen. CD4+ T-cell counts of at least 200/mm3 in last 6 months prior to transplant, with no previous serious opportunistic infections. Results: Survivors in the study were followed for a median of 2.4 years. The rate of patient survival was 84% at 1 year and 74% at 5 years. The corresponding graft survival rate was 93% and 84%. Conclusion: Using HIV-positive donors might resolve some of the problems we are experiencing in getting enough donors for our patients wit ESRD. In the USA the HOPE act was accepted in 2014 and this might now also impact on the use of HIV positive donors elsewhere in the world.

The purpose of this research was to explore the knowledge of, attitudes toward, and intention to care for HIV-positive patients among 223 Taiwanese nurses. They worked in many different settings and had a variety of levels of exposure to HIV-positive patients. The findings of this research revealed that most Taiwanese nurses lacked sufficient knowledge to prevent themselves from becoming infected in the workplace. Their attitude about giving care to HIV-positive patients was generally negative; most nurses stated that they did not intend to care for these patients. A regression analysis revealed that knowledge was not a significant predictor of intention. Attitudes about societal treatment of HIV-positive people and nursing care were significant predictors of intention. Implications for practice and education of Taiwanese nurses are discussed.

Between July 1995 and July 1997 we diagnosed bronchiectasis confirmed by CT scan chest in 25 (18 men and 7 women) out of 295 hospitalised patients with HIV infection who suffered from lower respiratory infection. Median age at time of diagnosis of bronchiectasis was 32 years old. The patients were mostly intravenous drug addicts. In all cases a previous pulmonary infection was revealed (Pneumocystis carinii pneumonia, tuberculosis, recurrent pneumonia) with impairment of immune status (CD4 media = 64.8 mm3). Presence of persistent or intermittent cough with purulent sputum, repeated low respiratory infection and abnormal chest radiograph were correlated to bronchiectasis by chest CT scan. We conclude, that there is a significant occurrence of bronchiectasis in patients with HIV infections and pulmonary disease, thus increasing morbidity and mortality in these patients and being the cause of repeated hospitalisations due to bacterial respiratory infections.

We report successful treatment of syphilitic uveitis in a case series of three Human immunodeficiency virus (HIV)-positive patients at Malaysia's Selayang Hospital eye clinic. All three patients with syphilitic uveitis were male, aged from 23 to 35 years old, with a history of high-risk behaviors. Of the patients, two presented with blurring of vision and only one patient presented with floaters in the affected eye. Ocular examination revealed intermediate uveitis (case 1 and case 3) and panuveitis (case 2). Each patient showed a high Venereal Disease Research Laboratory (VDRL) titer at presentation and they were also newly diagnosed as HIV positive with variable CD4 counts. All three patients responded well to a neurosyphilis regimen of intravenous penicillin G. At 3 months posttreatment, there was reduction in VDRL titer with improvement of vision in the affected eye. Diagnosis of syphilis needs to be ruled out in all cases of uveitis. All syphilitic uveitis cases should have HIV screening and vice versa, as syphilis is one of the most common infectious diseases associated with HIV-positive patients. Early detection and treatment are important for a good visual outcome.

AIM To determine whether HIV and the use of antiretroviral therapy is a risk factor for the development of ethambutol toxic optic neuropathy. To describe the clinical course of ethambutol toxic optic neuropathy in patients with HIV and to identify prognostic factors. METHODS The case notes of 14 consecutive patients referred to the neuro-ophthalmology clinic were reviewed. Data regarding HIV status, antiretroviral therapy, visual function, ethambutol therapy dosage, and ethambutol therapy duration were collected and analysed. RESULTS Eleven of the 14 patients were HIV positive. Ten of the HIV positive patients were receiving antiretroviral therapy. The mean dose of ethambutol was 17.25mg/kg/day. No statistically significant difference in mean dose, duration of therapy, age or CD4 count was found between those who showed visual improvement and those who did not. Delay in presentation of more than one month post symptom onset was correlated with poor visual outcome (P=0.001). CONCLUSION HIV and, perhaps more importantly, the potential mitochondrial toxic effects of Nucleoside analogue reverse transcriptase inhibitors (NRTIs) may be a risk factor for the development of toxic optic neuropathy from ethambutol therapy via a multiple hit effect. Delay in presentation results in poor visual outcome. Regular monitoring is recommended for HIV positive patients receiving antiretrovirals and requiring ethambutol therapy in order to avoid permanent visual loss. PMID:23991394

Dental care of HIV-positive individuals plays a vital role in improving their nutritional intake, medication tolerance and effectiveness, treatment success rate, and quality of life. It is therefore important to ensure optimal dental care of this group of people, especially since more of them, with or without knowledge of their serologic status, are now utilizing dental services. The objective of this study was to assess Nigerian dental students' willingness to treat HIV-positive individuals. A descriptive cross-sectional survey of all seventy-six final-year dental students of the University of Benin, Nigeria, was conducted in December 2007 using a self-administered questionnaire that elicited information on the students' demography, self-rated knowledge on HIV/AIDS, attitude towards homosexuals, infection control practices, occupational risk perception, and willingness to provide care for HIV-positive individuals. The response rate was 76.3 percent. Over 77 percent of the respondents were in the twenty-five to thirty years age group. The male-female ratio was approximately 1.6:1. HIV-related knowledge was reported as high by only 31 percent of the respondents. Eighty-one percent showed great interest in HIV-related information, while about half (53.4 percent) exhibited significant worry about occupational contagion. Forty-eight (82.7 percent) desired more knowledge about safety precautions during treatment of HIV patients. Fifty respondents (86.2 percent) reported good infection control practices. About three-fourths (74.2 percent) rated the risk of HIV contagion from patients high, while only one-fourth (25.8 percent) reported having an unsympathetic attitude towards homosexuals. Almost all respondents (98.3 percent) agreed that oral care for HIV-positive individuals improves their quality of life, but only 58.8 percent expressed a willingness to treat HIV-positive patients and only 46.5 percent said they will render volunteer dental services in HIV centers.

Epidermodysplasia verruciformis (EV) is a rare dermatological manifestation of the human papillomavirus (HPV) infection, which causes distinctive skin lesions in sun-exposed areas. Both inherited and acquired forms exist. Immunocompromised individuals, such as HIV patients, are at risk of acquired EV. EV poses challenges in its management and variable responses are seen in different individuals. In addition, EV carries a significant risk of skin malignancy with certain HPV types that require skin surveillance. A case of acquired EV in a HIV-positive patient is presented in this report.

HIV positive patients are a high risk population due to the alteration in their immune status. Healthcare associated infections (HAI) have not been well described in this population, with some risk factors reported inconsistently in the literature. The aim of this study was to describe the epidemiology as well as the underlying risk factors for HAI, specifically urinary tract infection (UTI), bloodstream infection (BSI) and respiratory tract infection (RTI). This was a retrospective cohort study conducted in three hospitals at an academic health system in New York City, over a two year period from 2006 to 2008. There were 3,877 HIV positive patient discharges in 1,911 patients. There were a total of 142 UTI, 106 BSI, and 100 RTI. The incidence rates were 4.35 for UTI, 3.16 for BSI and 2.98 for RTI. CD4 count and antiretroviral therapy were not associated with HAI. Significant predictors of UTI included urinary catheter, length of stay, female gender, steroids and trimethoprim-sulphamethoxazole (TMP-SMX); of BSI were steroids and TMP-SMX; and RTI were mechanical ventilation, steroids and TMP-SMX. Multivariable analysis indicated that TMP-SMX was significantly associated with an increased risk of infection for all three types of HAI [BSI odds ratio 2.55, 95% confidence interval (1.22–5.34); UTI odds ratio 3.1, 95% confidence interval (1.41–7.22); RTI odds ratio 5.15, 95% confidence interval (1.70–15.62)]. HIV positive patients are at significant risk for developing HAI, but the risk factors differ depending on the specific type of infection. The fact that TMP-SMX is a risk factor in these patients warrants further research as this may have significant health policy implications. PMID:25484924

Porokeratosis represents a group of disorders of epidermal keratinization that are characterized by one or more annular plaques surrounded by a histologically distinctive hyperkeratotic ridge-like border called the cornoid lamella. Many studies showed that organ transplantation and immunosuppression were associated in a significant number of cases. Furthermore, an association with squamous cell carcinoma and basal cell carcinoma has been noted in all variants of porokeratosis. The rarity of this disorder and its atypical clinical presentation - a single lesion on the thumb of an HIV-positive male patient - motivated this report.

Caring for pregnant women who are HIV-positive challenges family physicians to manage a disease that can be multigenerational, directly affecting parents and their offspring and indirectly affecting many others. I review current literature on prenatal, intrapartum, and postpartum care of HIV-positive patients. Management of HIV-positive women must be comprehensive, supportive, and sensitive to new information. PMID:8081123

Molluscum contagiosum (MC) is a very common benign self-limiting cutaneous viral infection caused by molluscum contagiosum virus. Disease is self-limiting in immunocompetent individuals, while it is severe and prolonged when associated with Human Immunodeficiency Virus (HIV) infection. The widespread and refractory mollusca of HIV disease occur especially on the face. In advanced stages of immunosuppression, giant or verrucous forms of MC may occur. Molluscum contagiosum tends to take a chronic course and is usually not responsive to various treatments in immunocompromised patients. Here, we present a HIV positive male patient with extensive papulonodular lesions over face, neck, bilateral upper limbs since 2 months, diagnosed as giant molluscum contagiosum, treated with cryotherapy with little improvement for few weeks after which patient did not turn up.

Although, in southern Europe, there has been considerable experience in the treatment of visceral leishmaniasis (VL) in HIV-positive patients, the optimal therapy has yet to be established. Pentavalent antimony salts, free amphotericin B deoxycholate (ABD) and lipidic formulations of amphotericin B are the drugs most commonly used. Treatment with pentavalent antimonials requires daily injections for 28 days, is not well tolerated and leads to initial clinical cure in only 66% of the co-infected cases. Free ABD has to be given, intravenously, for just as long, has significant toxicity and leads to initial clinical cure in even fewer cases (62%). In a prospective, comparative trial, treatment of co-infected cases with a pentavalent antimonial was found to have similar efficacy and toxicity to treatment with free ABD. The duration of treatment and the associated toxicity may both be reduced by the use of lipidic formulations of amphotericin B. Anecdotal evidence and the results of non-randomized trials indicate that treatment with liposomal amphotericin B is highly effective. In a comparative trial, amphotericin B lipid complex was found to be not only as effective as a pentavalent antimonial but also better tolerated. At the moment, however, such lipidic formulations have only been tested against VL/HIV cases in Europe, not elsewhere in the world, and they remain very expensive. However successful the treatment in terms of initial clinical cure, almost all VL/HIV cases develop VL relapses. Although the data available on secondary prophylaxis are limited and often inconclusive, it appears that regular treatment with a pentavalent antimonial drug, liposomal amphothericin B or amphotericin B lipid complex can reduce the incidence of leishmanial relapses in HIV-positive patients with VL. The development of new regimens, use of new oral drugs (such as miltefosine) and the development of new antileishmanial drugs could all improve the treatment of HIV-related VL in the

We examined 19 patients (17 men) with human immunodeficiency virus (HIV) infection and gastrointestinal symptoms to determine whether those symptoms were due to either a gastrointestinal tract infection or a defect in mucosal absorption because of an enteropathy. The erythrocyte folate and serum vitamin B12 levels were within normal limits in all of the patients. The serum ferritin level was elevated in 12. The xylose absorption test results were abnormal in 8 of the 13 patients able to complete the study. None of the duodenal aspirates yielded a pathogen. Light microscopy revealed nonspecific lymphocytic inflammation without infection in the stomach (in seven patients), the esophagus (in five), the duodenum (in two) and the rectum (in two). However, biopsy specimens were positive for Candida albicans in the esophagus (four patients), cytomegalovirus in the esophagus (one) and the rectum (two), Helicobacter pylori in the antrum (two), Treponema infection in the rectum (two) and Mycobacterium avium-intracellulare in the small intestine (one). Only three patients had a normal series of biopsy specimens. All of the patients had similar ultrastructural changes at the epithelial-stromal junction of the antral glands and in the intestinal crypts. We conclude that abnormal biochemical and endoscopic findings are common in HIV-positive patients with gastrointestinal symptoms. Defects in carbohydrate absorption and ultrastructural changes may be responsible for some aspects of HIV enteropathy. PMID:2207920

Kaposi's sarcoma (KS) is an AIDS-defining condition. Typically, KS affects the skin with or without visceral involvement. The extensive use of antiretroviral therapy (ART) has decreased the incidence of KS amongst the HIV-positive population. We report a case of a 40-year-old man with HIV-1 infection with CD4 count of 551 cells/mm(3)and an undetectable viral load who presented with two skin-coloured KS lesions on the prepuce of the penis. Diagnosis was confirmed by histopathology. He had been commenced on ART three years earlier with a nadir CD4 count of 255 cells/mm(3) He had achieved and maintained viral suppression since commencing ART. The patient was initially treated with cryotherapy and 5% imiquimod as the lesions were presumed to be warts. The lack of response to treatment prompted further investigation. We carried out a literature search of published cases of penile KS over the past 10 years. The majority of articles regarding penile KS were published in the pre-ART era and involved patients with AIDS. Over the past 10 years, published cases of penile KS have almost exclusively been in HIV-negative men. We found 10 published cases of penile KS in HIV-negative men and only one other published case of penile KS in a HIV-positive man, who had severe immune suppression with CD4 count below 200 cells/mm(3) This is the first case report to describe a HIV-positive patient stable on ART with a CD4 count above 200 cells/mm(3)and suppressed HIV-1 viral load, to develop two KS lesions on the penis. Clinicians have to remain suspicious of penile lesions and appreciate the crucial role a biopsy with histopathological analysis plays in confirming a diagnosis. In addition, this case illustrates that unusual presentations of KS can still occur in treated HIV-positive patients with sustained immune recovery.

Musculoskeletal manifestations of the human immunodeficiency virus (HIV) have been described since the outset of the global HIV epidemic. Articular syndromes that have been described in association with HIV include HIV-associated arthropathy, seronegative spondyloarthropathies (SPA) (reactive arthritis, psoriatic arthritis (PsA) and undifferentiated SPA), rheumatoid arthritis (RA) and painful articular syndrome. We carried out a computer-assisted search of PubMed for the medical literature from January 1981 to January 2015 using the keywords HIV, acquired immune-deficiency syndrome, rheumatic manifestations, arthritis, spondyloarthropathy, anti-TNF and disease modifying antirheumatic drugs. Only English language literature was included and only studies involving adult human subjects were assessed. There are challenges in the management of inflammatory arthritis in patients who are HIV-positive, including difficulties in the assessment of disease activity and limited information on the safety of immunosuppressive drugs in these individuals. This review focuses on the clinical characteristics of the inflammatory articular syndromes that have been described in association with HIV infection and discusses the therapeutic options for these patients.

Incidence of brain infections in Human Immunodeficiency Virus (HIV) positive patients is reduced after the availability of current high active antiretroviral therapy (HAART). Herpes Simplex Virus type 2 (HSV-2) is an infrequent cause of encephalitis in HIV patients despite it is frequently involved in sexual transmitted infections. Here, we report a case of HSV-2 encephalitis occurring in a patient without full suppression of HIV replication within the brain. A 38 year-old HIV infected man was admitted to our department because of recurrent generalized seizure and fever during the previous 24 hours. Eight months before our observation the patient was switched from a protease inhibitor based regimen to a rilpivirine-based regimen without any evidence of HIV-RNA replication in the plasma. When the patient was admitted in our hospital, he was febrile and moderately confused, no deficit of cranial nerves was reported, motility was conserved, but he was unable to walk. Laboratory examinations performed at admission demonstrated an increase of cerebrospinal fluid (CSF) protein and cells with lymphocyte prevalence, and normal CSF glucose. HSV-2-DNA and HIV-RNA were present within CSF at admission. Nuclear Magnetic Resonance imaging of the brain revealed lesions of the medial part of both temporal lobes including hippocampus without any sign of bleeding. A 21-day course of acyclovir therapy was administered with consistent improvement of clinical findings and disappearance of HSV-2-DNA within CSF. After the episode, HAART was switched to a regimen with high CSF penetrability containing abacavir, lamivudine, darunavir and ritonavir. Twelve months after HSV-2 encephalitis neurologic evaluation was normal, but symptoms of depression were reported, HIV-RNA remained undetectable both in the plasma and CSF, and CD4+ lymphocytes were above 500/μL. No opportunistic infection was reported. Patients switched to regimen well tolerated such those containing rilpivirine, that have

HIV and poor mental health are intricately related. In settings of poverty, both are often rooted in structural factors related to material and social deprivation. We performed a qualitative analysis to understand factors contributing to poor emotional health and its impact among impoverished Peruvian HIV-infected individuals. We conducted focus group discussions with patients and providers consisting of semistructured, open-ended questions. Qualitative analysis provided insight into the profound impact of depression, isolation, stigma, and lack of social support among these patients. Living with HIV contributed significantly to mental health problems experienced by HIV-positive individuals; furthermore, long-standing stressors-such as economic hardship, fragmented family relationships, and substance use-shaped patients' outlooks, and may have contributed not only to current emotional hardship but to risk factors for contracting HIV as well. Once diagnosed with HIV/AIDS, many patients experienced hopelessness, stigma, and socioeconomic marginalization. Patients tended to rely on informal sources of support, including peers and community health workers, and rarely used formal mental health services. In resource-poor settings, the context of mental health problems among HIV-positive individuals must be framed within the larger structural context of poverty and social exclusion. Optimal strategies to address the mental health problems of these individuals should include integrating mental health services into HIV care, task shifting to utilize community health workers where human resources are scarce, and interventions aimed at poverty alleviation.
In this phase I clinical trial, HIV-positive patients receiving combination antiretroviral therapy who have cancer that has recurred after or has not responded to previous treatment will receive the immune checkpoint inhibitor pembrolizumab.

The dental treatment of HIV-positive individuals has undergone a change from the management of HIV-associated oral lesions to routine comprehensive dental care. To the authors' knowledge, this is the first report in which palatal soft tissue grafts were used for vestibuloplasty in an HIV-positive patient with a shallow mandibular vestibule. No adverse sequelae were seen during follow-up.

To identify clinical parameters in association with human papilloma virus (HPV) genotypes and histopathology diagnosis in HIV-positive patients with external condylomata acuminata (ECA), 400 Chilean HIV-positive patients were included in the study. Forty-seven patients presented ECA. Clinical parameters and socio demographic data were recorded. Histopathology study and HPV linear array genotyping assay were performed. Intraepithelial neoplasia (IEN) grade 2 or 3 was found in 8.5% of patients, associated to HPV-16. Patients were mainly single, MSM, with history of sexually transmitted disease (STD), multiple sexual partners, receiving antiretroviral therapy and with recurrent lesions. All ECA were mainly perianal, grey or pink colored, exophytic with less than two years evolution. No clinical parameter could predict the development of high grade IEN in HIV patients with ECA. It seems necessary to perform biopsy and genotype all HIV positive patients with ECA. PMID:21799573

The objective of this study was to compare the frequency of herpes simplex virus type 1 (HSV-1), Epstein-Barr virus (EBV) and human cytomegalovirus (HCMV) in subgingival plaque, saliva and peripheral blood of HIV-positive and-negative patients with periodontal disease. Fifty HIV-positive subjects (23 with gingivitis, 27 with periodontitis) and 50 healthy HIV-negative patients with chronic periodontitis were included in the study. Parameters of probing depth (PD), clinical attachment level (CAL), gingival index and plaque index were recorded. The samples were processed for viral identification by the nested polymerase chain reaction technique. HCMV was the most prevalent virus in HIV-positive (82%) and-negative patients (84%), and the detection in the three samples was similar (p>0.05). HSV-1 was the least prevalent virus in both groups, being detected in similar frequencies in oral sites and in peripheral blood. EBV-1 was found more frequently in saliva and subgingival plaque of HIV-positive patients than in HIV-negative patients (p< or =0.05). EBV-1 was more frequently recovered in oral sites of HIV-positive patients than in HIV-negative patients.

There are few reports on focal epithelial hyperplasia (FEH) in association with human immunodeficiency virus (HIV) infection; thus the relationship between them has not been completely clarified yet. We present a case of recurrent FEH in an HIV-positive man (the first described in Belgium), which, according to the PCR-DNA testing, was due to human papilloma virus type 13 (HPV13). To our knowledge, based on the accessible literature, this type of HPV has not been detected in any other documented study of FEH in HIV-positive patients before. Our patient experienced three recurrences of FEH in 1 year. It is therefore suggested that immunodeficiency due to HIV infection is responsible for the HPV-related FEH and the subsequent recurrences. In order to support the consideration of FEH as an oral manifestation of an HIV-related opportunistic infection, every new 'HPV-type' oral lesion in HIV-positive patients must be completely documented.

Partner notification as a means of contact tracing human immunodeficiency virus (HIV)-infected persons remains controversial. It is argued against by many gay activists, while primary public health officials and leaders in ethnic communities continue to support this as a means of identifying unknown cases. Human immunodeficiency virus-positive patients were interviewed to determine if partner notification could be a useful instrument. Based on interviews, patients at risk of infection through heterosexual contact were able to identify most of their sexual partners; the majority of these patients were women. Twenty-two of 22 women infected heterosexually were able to identify all of their sexual partners. Five of 8 heterosexual men were able to identify all of their sexual partners, but these men were infected through intravenous drug use. Six of 44 homosexual men interviewed were able to make these identifications. Two focus groups of homosexual men who were HIV-positive patients were organized; each was asked one question. Men in group B were asked if they could identify HIV-positive persons whom they suspected were not in a treatment program. Men in group A were asked if they they thought they knew HIV-positive persons still practicing unsafe sex. Thirteen of the 14 patients in group A were able to identify 30 persons they felt were still practicing unsafe sex; 17 of 30 tested HIV-positive and 9 were unaware of their status. The 14 patients in group B identified 15 persons they felt were HIV-positive; 11 were found to be HIV-positive and 8 were unaware of their status. These findings suggest that partner notification definitely has a role in heterosexual contact tracing, and focused intervention is a more cost-effective approach to early intervention.

Patients who have contracted the human immunodeficiency virus (HIV) often require a diagnostic or therapeutic thoracic procedure. To determine the clinical benefits of a noncardiac pulmonary intervention in the treatment of HIV-positive individuals, 82 patients with HIV-positive serology who underwent a thoracic procedure for illnesses related to acquired immunodeficiency syndrome (AIDS) between 1987 and 1990 were reviewed. Pneumocystis carinii pneumonia was the most common opportunistic infection and was the initial manifestation for establishing the HIV-positive serology in 54 patients (66%). Fiberoptic bronchoscopy was performed in 74 patients (90%), closed tube thoracostomy in 9 (11%), thoracentesis in 3 (4%), thoracostomy and lung resection in 2 (2.4%), pericardial window in 1 (1.2%), and tracheostomy in 1 (1.2%). The operation was useful in 46 patients (56%) and improved the clinical short-term outcome of 53 patients (64%). Nonfatal complications occurred in only two patients (2.4%). There were no deaths directly caused by the thoracic procedure within the first 30 days. However, overall 8 patients (10%ZZ) succumbed to infectious complications of AIDS. We conclude that thoracic procedures directed toward pulmonary opportunistic infections and their complications in HIV-positive patients are beneficial and may offer an improved short-term outcome.

The purpose of this study was to assess knowledge, practices and attitudes towards HIV positive and AIDS patients amongst 71 dental auxiliaries using on a self administered questionnaire. 65 (91.5%) returned the questionnaire. In general, respondents' knowledge was fair. 87.7% felt that dentistry as practised in Kenya today carries a high risk of transmission of HIV primarily because of improper sterilization of instruments. 72.3% had changed their sex habits since they became aware of the dangers posed by indiscriminate sex. Over 67% used gloves and masks routinely when assisting in the management of AIDS patients. Over 33% did not use protective eye wear and protective covers on operatories routinely because they were not provided by the employer. 27.7% felt that AIDS and HIV positive health workers should stop treating patients. 64.6% advocated that the cost of buying materials and equipment to prevent cross infection be met by the patient and the employer or dentist. 23.1% supported the idea that HIV positive and AIDS patients be isolated from uninfected individuals. In conclusion, a substantial number of dental auxiliaries were wanting in their knowledge, practices and attitudes towards HIV positive/AIDS patients.

The purpose of this study was to investigate the characteristics and infection control practices of dentists in Mexico City in relation to their willingness to treat AIDS/HIV-positive patients. The population study encompassed Mexico City dentists who were selected according to a geographic criterion. A questionnaire was delivered personally to each participant, and multiple logistic regression was used for data analysis. A total of 598 dentists participated in the study. The response rate was 99.3% (598/602). Seventy-four percent (444) of the dentists said they would be willing to treat AIDS/HIV-positive patients. Among the variables associated with the prediction of willingness to treat these patients were glove-wearing patterns (odds ratio, 2.39; confidence interval, 1.4-4.2), types of available sterilization equipment (odds ratio = 2.42; confidence interval, 1.4-4.1), fear of losing non-AIDS/HIV-positive patients (odds ratio = 4.28; confidence interval, 2.3-8.4), and risk perception of HIV transmission (odds ratio = 2.66; confidence interval, 1.5-4.9). An interaction was found between perception of risk of HIV transmission and increase in costs (odds ratio = 3.35; confidence interval, 1.3-8.9). Approximately 26% of the Mexico City dentists included in the study were not willing to treat AIDS/HIV-positive patients. Educational programs aimed at misperceptions appear to be warranted.

Advent of antiretroviral therapy has increased survival of patients with human immunodeficiency virus (HIV) infections, with the result that some of these patients now develop degenerative diseases, such as atherosclerotic aneurysms. Degenerative thoracoabdominal aortic aneurysm is rare in HIV patients. In this report, a 63-year-old male patient with HIV submitted to open repair of thoracoabdominal aortic aneurysm. The patient did not suffer any type of complication in the perioperative period and remained well in a 28-month follow-up period. In summary, open repair still remains a good alternative for aortic complex aneurysms even in HIV patients.

The dihydropteroate sulfate (DHPS) gene is associated with resistance to sulfa/sulfone drugs in Pneumocystis jirovecii. We investigated the DHPS mutation rate in three groups of Iranian HIV-positive and HIV-negative patients by polymerase chain reaction-restricted fragment length polymorphism analysis. Furthermore, an association between P. jirovecii DHPS mutations and strain typing was investigated based on direct sequencing of internal transcribed spacer region 1 (ITS1) and ITS2. The overall P. jirovecii DHPS mutation rate was (5/34; 14.7%), the lowest rate identified was in HIV-positive patients (1/16; 6.25%) and the highest rate was in malignancies patients (3/11; 27.3%). A moderate rate of mutation was detected in chronic obstructive pulmonary disease (COPD) patients (1/7; 14.3%). Most of the isolates were wild type (29/34; 85.3%). Double mutations in DHPS were detected in patients with malignancies, whereas single mutations at codons 55 and 57 were identified in the HIV-positive and COPD patients, respectively. In this study, two new and rare haplotypes were identified with DHPS mutations. Additionally, a positive relationship between P. jirovecii strain genotypes and DHPS mutations was identified. In contrast, no DHPS mutations were detected in the predominant (Eg) haplotype. This should be regarded as a warning of an increasing incidence of drug-resistant P. jirovecii strains.

We report the case of a young male patient, VIH (+), who was admitted in our hospital with severe epigastric pain. Endoscopical and histological diagnosis was primary gastric non-Hodgkin lymphoma without Helicobacter pylori. The patient was treated with chemotherapy by CHOP scheme (6 cycles), with high clinical improvement and endoscopical and histological regression of the lesion. We comment some features of this peculiar association.

Gelatinous bone marrow transformation has been identified in patients with anorexia, malignancy, malabsorption, and HIV/AIDS. This represents a deposition of gelatinous material within the bone marrow, along with atrophy. We report the case of an HIV-seropositive man who presented with low back pain related to his gelatinous bone marrow changes. PMID:17637880

Kaposi's sarcoma-associated herpesvirus (KSHV) is the causative agent of Kaposi sarcoma (KS), one of the leading cancers in human immunodeficiency virus (HIV)-infected patients in Zambia. KSHV was detected in the human central nervous system (CNS) by polymerase chain reaction (PCR) analysis, but tissue location and cell tropism for KSHV infection has not been established. Given the neurotropism exhibited by other herpesviruses and the frequent coinfection of HIV-positive individuals by KSHV, we sought to determine whether the central nervous system (CNS) can be infected by KSHV in HIV-positive Zambian individuals. Postmortem brain tissue specimens were collected from individuals coinfected with KSHV and HIV. PCR and Southern blots were performed on DNA extracted from the brain tissue specimens to verify KSHV infection. Immunohistochemical analysis and immunofluorescent microscopy were used to localize and identify KSHV-infected cells. Tropism was further established by in vitro infection of primary human neurons with rKSHV.219. KSHV DNA was detected in the CNS from 4 of 11 HIV-positive individuals. Immunohistochemical analysis and immunofluorescent microscopy demonstrated that KSHV infected neurons and oligodendrocytes in parenchymal brain tissues. KSHV infection of neurons was confirmed by in vitro infection of primary human neurons with rKSHV.219. Our study showed that KSHV infects human CNS-resident cells, primarily neurons, in HIV-positive Zambian individuals.

This is a case report about Porphyria cutanea tarda (PCT) and its relationship with the infection caused by the human immunodeficiency virus (HIV). Cutaneous porphyria is an illness caused by enzymatic modification that results in partial deficiency of uroporphyrinogen decarboxylase (Urod), which may be hereditary or acquired. Several studies suggest that HIV infection associated with cofactors might trigger the development of porphyria cutanea tarda. In this case report, we present a patient infected with HIV, who after the introduction of antiretroviral therapy (ART) enjoyed clinical improvement of porphyria cutanea tarda symptoms. PMID:27579753

Molluscum Contagiosum (MC) is a skin infection caused by a double-stranded DNA virus of the family Poxviridae that replicates in the human epidermis, affecting mainly children and young sexually active adults and causing flesh colored papular lesions with central umbilication with an average size of 3-5mm, although atypical lesions that reach great size (Giant Molluscum Contagiosum), 10-15mm, can be seen in almost any immunodeficiency condition. We report the case of a 35 year old male patient with C3 HIV disease with an abdominal pathology associated to skin lesions predominantly in the forehead and scalp that reached sizes over 5mm, diagnosed as Giant Molluscum Contagiosum by skin biopsies.

Aims To gauge the effect of disease state and disease progression on the glucuronidation and sulphation of paracetamol (APAP) among HIV-positive patients and patients with AIDS. Methods The extent of APAP glucuronidation and APAP sulphation was assessed using a spot urine sample collected 4 h after the oral administration of 500 mg of APAP to 108 patients with AIDS or HIV infection. The molar concentrations of APAP and its glucuronide and sulphate metabolites were determined using a validated h.p.l.c. method and glucuronidation and sulphation indices were constructed using APAP metabolite/APAP molar concentration ratios. Results No effect of disease state, AIDS vs asymptomatic HIV positive vs control, on APAP glucuronidation or sulphation was observed. The patient population was studied over time and disease progression also did not significantly alter the calculated glucuronidation and sulphation indices. The effect of the concomitant administration of other therapeutic agents was assessed and in the cross sectional portion of the study dapsone appeared to significantly decrease APAP sulphation as did lamivudine. In the longitudinal portion of the study the latter effect was not observed but zidovudine was seen to increase APAP glucuronidation. The data also indicates that APAP glucuronidation may be reduced in patients who are >10% below their ideal body weight. PMID:10594484

Dapsone is commonly used for the prophylaxis of Pneumocystis jiroveci pneumonia in patients with a diagnosis of HIV infection who have allergies to sulfa-based drugs. Dapsone has several adverse effects in its profile that make it a potentially dangerous second-line agent. We report an adverse effect encountered in an HIV-positive patient receiving dapsone and review the common adverse effects encountered with this alternative treatment option.

The purpose of this study was to evaluate the prevalence of oral lesions in HIV-positive patients attending the Specialized Service for Infectious-contagious Diseases and Parasitoses of the Health Secretariat of the State of Pará (URE-DIPE/SESPA), in the city of Belém, PA, Brazil. A total of 79 HIV-positive patients (53 males and 26 females) were examined. Clinical and epidemiological evaluations were done by correlating the lesions with gender, race, chronological age, risk behavior and prevailing immune status (CD4+ cells count). Lesion location and the presence of associated factors, such as alcohol use, smoking and denture wearing, were quantified individually for each type of lesion using a diagnostic pattern based on the clinical aspects. Approximately 47% of the patients (n=37) presented some type of oral lesion. Candidiasis (28%) and periodontal disease (28%) were the most common, followed by cervical-facial lymphadenopathy (17.5%). Other lesions observed were hairy leukoplakia, melanin hyperpigmentation, ulcerative stomatitis (aphthous), herpes simplex, frictional keratosis and pyogenic granuloma. This analysis presented some relevance as to the statistical data. Concerning CD4+ cells, most lesions manifested with the reduction of the CD count. There were a larger number of HIV-positive female heterosexual patients. Alcohol and/or smoking were strongly associated with the occurrence of hairy leukoplakia in these patients. Candidiasis and periodontal disease were the most common oro-regional clinical manifestations in the patients. PMID:19082393

We describe four cases of hand osteoarthritis in patients with HIV infection under antiretroviral treatment. A 36-year-old HIV-infected man came for consultation in 2007 with hand osteoarthritis. He was diagnosed HIV positive by sexual transmission in 1997. A 52-year-old HIV-infected woman came for consultation with hand osteoarthritis started in 2006. She was diagnosed HIV positive in 1986 by sexual transmission. A 57-year-old man presented hand osteoarthritis. This former IV drug user was diagnosed HIV positive in 1989. A 61-year-old HIV-infected man presented with hand osteoarthritis started in 2010. He had been contaminated with HIV in 1990 by sexual transmission. For all patients, there were neither clinical nor biological manifestations suggesting inflammatory arthritis. X-rays showed signs of hand osteoarthritis. CD4 cell count was over 500/mm(3) and the viral load was below 20 copies/mL under treatments. These four cases show osteoarthritis in HIV-infected patients. Hand osteoarthritis did not seem to be linked to aging or to an antiretroviral treatment's side effect, but rather to the HIV infection itself, and it may pass through a metabolic syndrome. We described a possible association between early-developed hand osteoarthritis and HIV-infected patients. Clinicians should consider osteoarthritis when they are confronted with HIV-infected patients with chronic hand pain.

Background Different factors can be responsible for the increased prevalence of dental caries and missing teeth in HIV-positive patients. Objectives This study evaluates dental health status and its relationship with social, behavioral, and medical factors in HIV-positive patients under the coverage of Zahedan University of Medical Sciences in Southeast Iran. Patients and Methods In a cross-sectional study, the dental health status of 119 HIV-positive patients was assessed in accordance with WHO indices and included decayed, missing, and filled teeth (DMFT). A questionnaire on different social, behavioral, and medical variables was filled out for every case and the relationship and correlation of the variables to dental health status were investigated using One-way ANOVA, the Kruskal Wallis test, the t-test, the Mann-Whitney test, Spearman’s rho correlation coefficient, and Pearson correlation. Results The mean value of DMFT index was 11.87 ± 8.08, where the mean values of decayed and missing teeth were 8.42 ± 5.44 and 3.43 ± 4.07, respectively. DMFT index, decayed, and missing teeth correlated only with age (P < 0.0001, P = 0.009, P < 0.0001) and duration of HIV involvement (P = 0.004, P = 0.031, P = 0.007). Conclusions The dental health status of HIV-positive patients in this region was almost inappropriate. Most social, behavioral, and medical factors had no influence on dental health; only a correlation between dental health, age, and duration of HIV involvement was observed. PMID:27622173

Amongst the main opportunistic diseases that affect the HIV-positive patient, histoplasmosis is found. This systemic mycosis caused by the fungus Histoplasma capsulatum has the capacity to disseminate from the lung to the skin and oral mucosa. Oral lesions of histoplasmosis can be found with ulcerated or nodular aspect, being always very painful and infiltrating the mucosa. When they are present in the mouth, they strongly indicate the presence of some kind of immunosuppression. This study shows the disease's evolution in an HIV-positive patient, who presented several ulcerated lesions in the oral cavity and facial skin. The symptomatology and clinical aspects of the lesions were not specific for the disease, and due to this, the diagnosis was obtained by cytological smear and oral biopsy. The results of the exams defined the disseminated picture of the infection. The treatment plan involved the use of amphotericin B for the lesions' remission, and, following this, itraconazole was administered in the maintenance phase.

We describe the presentation and treatment of an HIV-positive patient with an oral ranula, and review the literature. Ranulas are mucoceles or retention cysts formed by the extravasation of mucus from the sublingual gland, presumably due to continued production of saliva in the presence of ductal obstruction. Oral ranulas in children are rare and the overall prevalence of mucoceles has been reported as 0.08% in children aged 0-12 years. However, there has been a documented increased occurrence in HIV-positive patients. This has been attributed to a blockage of the salivary gland by inflammation and peri-ductal fibrosis following HIV-associated salivary gland disease. Oral lesions may indicate infection with HIV and can also predict progression of HIV to AIDS. The most common oral manifestation is oral candidiasis occurring in 67% of children with HIV. Following this salivary gland disease, periodontal and gingival disease and herpes simplex are the next most common. The exact prevalence of ranulas in an HIV population is not known but the occurrence of a paediatric patient with HIV having at least one oral lesion has been documented as high as 63% and salivary gland disease at 50%. The true extent of the relationship between HIV and ranula is as yet unknown. This represents the only reported case of oral ranula in an HIV-positive patient in the UK.

Candida dubliniensis is a recently described yeast species, closely related to Candida albicans. This work represents the first general survey of the carriage of C. dubliniensis in the oral cavities of HIV-positive patients in Argentina. We studied 133 strains isolated from 162 HIV-positive patients, using the following identification tests: chlamydospore production on corn meal agar with Tween 80; colony color on CHROMagar Candida media; differential growth at 45 degrees C on potato dextrose agar; D-xylose assimilation; chlamydospore formation on sunflower seed agar (SSA); carbohydrate assimilation profiles using the API 20 C Aux commercial kit and PCR using primers that hybridize to the class IV intron of the ACT1 gene. Out of the 133 strains, 21 were identified as C. dubliniensis, representing approximately 13% of the 162 patients in this study. From these data, we conclude that although the PCR assay is the most reliable method, clamydospore formation on SSA is an easier and less expensive test for the screening of C. dubliniensis in the routine laboratory. Our results show that C. dubliniensis has a high prevalence among HIV-positive patients in Argentina.

The aim of the present study was to evaluate in HIV-positive patients with bacterial pneumonia, the diagnostic value of a new endoscopic technique that uses a single catheter to perform a telescopic plugged catheter (TPC) followed by a modified protected bronchoalveolar lavage (mpBAL). Fifty-eight HIV-positive patients with respiratory infection were included in the study. Samples from TPC and mpBAL were cultured quantitatively. Standard bronchoalveolar lavage was performed to rule out opportunistic infections. According to the clinical and microbiological results, patients were classified in the study group (27 with bacterial pneumonia) or the control group (31 without bacterial pneumonia). Sensitivity of TPC was 56% [95% confidence intervals (CI) 37-75%] and its specificity was 100%; these figures were 56% (CI, 37-75%) and 94% (CI, 86-100%) for mpBAL. When both techniques were assessed together, sensitivity increased to 70% (CI, 53-87%). The use of a single catheter reduced the cost of the originally described pBAL procedure by approximately 50%. The use of a single catheter to perform a TPC followed by a mpBAL can improve the diagnostic yield in HIV-positive patients with bacterial pneumonia, and reduces its cost.

The purpose of this research was to understand how stepped counseling intervention affects quality of life in newly diagnosed HIV-positive patients. The study made use of quasi-experimental methodology that included a three-step interview process over 45 days. The theoretical framework supporting interviews with 32 newly diagnosed HIV-positive patients in northern Taiwan included a combination of rational-emotive therapy, cognitive-behavior therapy, and health education. Participants were divided into an experimental and control group of equal size. Data collection also included responses to the WHOQOL-HIV instrument at the beginning and end of each interview session. Responses were analyzed with the SPSS software package. The results showed a 25-point difference between pre- and post-test scores in the experimental group (SD = 3.2) and a 6 point difference in the control group (SD = 4.3). The results indicate that stepped counseling techniques are effective in helping this patient population to adjust to the physical, emotional, social, and environmental stresses associated with their newly diagnosis. The researchers suggest that stepped counseling be used with all newly diagnosed HIV-positive Taiwanese patients in all hospitals and clinics to promote adaptive abilities and to control the further spread of HIV.

We report a case of unusual cutaneous toxoplasmosis manifestation in a HIV-positive patient. He presented with hard and painful nodular lesions on the arms, hands and chest. Serology tests for anti-Toxoplasma antibody were negative. However, histopathologic examination of the lesion revealed foci of macrophages containing crescent-shaped organisms resembling the zoites of the protozoan parasite Toxoplasma gondii. Ultrastructure examination under electron microscopy and PCR confirmed the organism as T. gondii.

The onset of opportunistic infections in HIV-positive patients is generally associated with a low CD4 count. Oral manifestations can be the first clinical sign of the infection and also determine the progression of disease. The purpose of this study was to determine the prevalence of oral soft tissue manifestations and their relationship with the degree of immunosuppression observed in HIV-positive patients. 100 HIV-positive patients were examined. Oral lesions were evaluated according to EEC clearing house criteria. The degree of immunosuppression was based on the CD4 count closest to the oral examination. Data were analyzed using Student's t-test and chi-square test. The most common oral lesions were rampant caries (54%), periodontal disease (44%), and hyperpigmentation (42%). Salivary glands enlargements and leukoplakia were associated with more severe immunosuppression. According to the results, it seems that occurrence of only some of oral lesions are related to the degree of immunosuppression and such lesions can be considered as indicators of the progression of the HIV infection.

Kaposi sarcoma is a neoplasm commonly associated with human herpesvirus 8 and HIV/AIDS. We present a 44-year-old African immigrant woman who presented to the emergency department after several months of abdominal pain. She was found to be HIV positive, and computed tomography demonstrated numerous lesions of the lungs, liver, and spleen, gastric wall thickening, and several lytic lesions of the spine. Fluoroscopy-guided biopsy of a lytic lesion of the spine yielded the diagnosis of Kaposi sarcoma. AIDS-related Kaposi sarcoma with osseous involvement is rare, with approximately 30 cases reported in the literature. When osteolytic lesions are encountered in an HIV-positive patient, Kaposi sarcoma should remain in the differential.

DLBCL is the most common lymphoma subtype occurring in older populations as well as in younger HIV infected patients. The current treatment options for DLBCL are effective for most patients yet the relapse rate is high. While many biomarkers for DLBCL exist, they are not in clinical use due to low sensitivity and specificity. In addition, these biomarkers have not been studied in the HIV context. Therefore, the identification of new biomarkers for HIV negative and HIV positive DLBCL, may lead to a better understanding of the disease pathology and better therapeutic design. Protein biomarkers for DLBCL were determined using MALDI imaging mass spectrometry (IMS) and characterised using LC-MS. The expression of one of the biomarkers, heat shock protein (Hsp) 70, was confirmed on a separate cohort of samples using immunohistochemistry. The biomarkers identified in the study consisted of four protein clusters including glycolytic enzymes, ribosomal proteins, histones and collagen. These proteins could differentiate between control and tumour tissue, and the DLBCL immunohistochemical subtypes in both cohorts. The majority (41/52) of samples in the confirmation cohort were negative for Hsp70 expression. The HIV positive DLBCL cases had a higher percentage of cases expressing Hsp70 than their HIV negative counterparts. The non-GC subtype also frequently overexpressed Hsp70, confirming MALDI IMS data. The expression of Hsp70 did not correlate with survival in both the HIV negative and HIV positive cohort. This study identified potential biomarkers for HIV negative and HIV positive DLBCL from FFPE tissue sections. These may be used as diagnostic and prognostic markers complementary to current clinical management programmes for DLBCL.

Background Treatment-related reductions in morbidity and mortality among human immunodeficiency virus (HIV)-positive patients have been attenuated by cigarette smoking, which increases risk of cardiovascular, respiratory, and neoplastic diseases. This study investigated factors associated with smoking status among HIV-positive patients. Methods This cross-sectional study included 2,464 HIV-positive patients attending the HIV Clinic at the University of Alabama at Birmingham between April 2008 and December 2013. Smoking status (current, former, never), psychosocial factors, and clinical characteristics were assessed. Multinomial logistic regression was used to obtain unadjusted and adjusted odds ratios (OR) and 95% confidence intervals (CI) for the association of the various factors with smoking status. Results Among HIV-positive patients (mean age 45 years, 75% male, 55% African-American), the majority reported a history of smoking (39% current and 22% former smokers). In adjusted models, patient characteristics associated with increased odds of current smoking were male gender (OR for heterosexual men, 1.8 [95% CI: 1.3–2.6]; for men who have sex with men, 1.5 [1.1–1.9]), history of respiratory diseases (1.5 [1.2–1.9]), unsuppressed HIV viral load (>50 copies/mL) (1.5 [1.1–1.9]), depression (1.6 [1.3–2.0]), anxiety (1.6 [1.2–2.1]), and prior and current substance abuse (4.7 [3.6–6.1] and 8.3 [5.3–13.3] respectively). Male gender, anxiety, and substance abuse were also associated with being a former smoker. Conclusions Smoking was common among HIV-positive patients, with several psychosocial factors associated with current and former smoking. This suggests smoking cessation programs in HIV clinic settings may achieve greater impact by integrating interventions that also address illicit substance abuse and mental health. PMID:26767146

The ethical and legal issues surrounding the healthcare provider's obligation to provide care for patients have been a topic of debate since the beginning of modern medicine. The human immunodeficiency virus (HIV)-positive patient requesting cosmetic or elective surgery provides yet another situation in which the physician's ethical and legal responsibilities for the patient become a topic of debate. The risks involved to the physician and patient are first discussed, and then current ethical theory and legal decisions are reviewed. Finally, some conclusions are attempted from the varied opinions in the literature surrounding this controversial topic.

Chronic kidney disease is common in HIV positive patients and renal tubular dysfunction has been reported in those receiving combination antiretroviral therapy (cART). Tenofovir (TFV) in particular has been linked to severe renal tubular disease as well as proximal tubular dysfunction. Markedly elevated urinary concentrations of retinal-binding protein (RBP) have been reported in patients with severe renal tubular disease, and low-molecular-weight proteins (LMWP) such as RBP may be useful in clinical practice to assess renal tubular function in patients receiving TFV. We analysed 3 LMWP as well as protein and albumin in the urine of a sample of HIV positive patients. In a cross-sectional fashion, total protein, albumin, RBP, cystatin C, and neutrophil gelatinase-associated lipocalin (NGAL) were quantified in random urine samples of 317 HIV positive outpatients and expressed as the ratio-to-creatinine (RBPCR, CCR and NGALCR). Exposure to cART was categorised as none, cART without TFV, and cART containing TFV and a non-nucleoside reverse-transcriptase-inhibitor (TFV/NNRTI) or TFV and a protease-inhibitor (TFV/PI). Proteinuria was present in 10.4 % and microalbuminuria in 16.7 % of patients. Albumin accounted for approximately 10 % of total urinary protein. RBPCR was within the reference range in 95 % of patients while NGALCR was elevated in 67 % of patients. No overall differences in urine protein, albumin, and LMWP levels were observed among patients stratified by cART exposure, although a greater proportion of patients exposed to TFV/PI had RBPCR >38.8 μg/mmol (343 μg/g) (p = 0.003). In multivariate analyses, black ethnicity (OR 0.43, 95 % CI 0.24, 0.77) and eGFR <75 mL/min/1.73 m2 (OR 3.54, 95 % CI 1.61, 7.80) were independently associated with upper quartile (UQ) RBPCR. RBPCR correlated well to CCR (r2 = 0.71), but not to NGALCR, PCR or ACR. In HIV positive patients, proteinuria was predominantly of tubular origin and microalbuminuria
Background Chronic kidney disease is common in HIV positive patients and renal tubular dysfunction has been reported in those receiving combination antiretroviral therapy (cART). Tenofovir (TFV) in particular has been linked to severe renal tubular disease as well as proximal tubular dysfunction. Markedly elevated urinary concentrations of retinal-binding protein (RBP) have been reported in patients with severe renal tubular disease, and low-molecular-weight proteins (LMWP) such as RBP may be useful in clinical practice to assess renal tubular function in patients receiving TFV. We analysed 3 LMWP as well as protein and albumin in the urine of a sample of HIV positive patients. Methods In a cross-sectional fashion, total protein, albumin, RBP, cystatin C, and neutrophil gelatinase-associated lipocalin (NGAL) were quantified in random urine samples of 317 HIV positive outpatients and expressed as the ratio-to-creatinine (RBPCR, CCR and NGALCR).

Plasmablastic lymphoma is an aggressive form of lymphoma diffuse large B cell Lymphoma, initially described in HIV positive patients associated with lesions in the oral cavity. It is about 2% of NHL associated with HIV. This entity currently represents a challenge for the diagnosis and treatment, showing a poor long-term prognosis. This report describes a patient with VIH on HAART and CD4 count in 490 cells/ml associated with Plasmablastic lymphoma that involves rectum and bone marrow. The patient received 6 cycles of EPOCH regimen with complete response.

After a decade of steady decline, syphilis has reemerged within the past few years and it is seeping back into the HIV negative population. We describe herein 16 consecutive cases of neurosyphilis and compare its clinical characteristics. Of the 16 patients, 14 (87%) were men. Mean age at onset was 43 years old (range: 23-82). Twelve patients (75%) were HIV positive; stage was B2 in 2 patients, B3 and C2 in one patient each, and C3 in 8 patients. The clinical presentation was meningitis in 6 (40%), stroke in 3 (18%), ocular manifestations in 4 (27%), and psychiatric manifestations in 2 (13%) cases. Five additional patients had ocular involvement after a formal ophthalmologic examination. High venereal disease research laboratory test (VDRL) titers in serum and cerebrospinal fluid (CSF) were found. Patients in C3 stage of HIV had less CSF pleocytosis (<5 cells/mm(3)) than patients in earlier stages (P=0.018). Disease onset was earlier in patients older than 50 years old with HIV (P=0.049). We found that meningitis, ocular manifestations and stroke were the most common clinical findings in early syphilis. Moreover, stroke included the carotid and cerebrobasilar vascular territories. CSF VDRL continues to be a crucial test in all idiopathic cases of meningitis, stroke and uveitis, regardless of the HIV status or CSF pleocytosis. Except for less pleocytosis, there were no important differences between HIV positive and HIV negative patients.

To evaluate the effects of a periodontal therapy with subsequent application of an octenidine (OCT)-based antiseptic in HIV-positive patients receiving highly active antiretroviral therapy. HIV-positive patients with a clinically diagnosed periodontal disease were randomly divided into two groups (n = 30/group). Both groups initially received a periodontal therapy. Patients in the OCT group additionally used an OCT-based mouthwash. Subgingival plaque samples and periodontal indices were analysed prior to treatment onset as well as one and 3 months post-treatment. Periodontal therapy has resulted in a significant decrease in the values of all periodontal indices one and 3 months following the therapy completion (P = 0.000). The effects of the two applied therapeutic protocols differed significantly in terms of the variation in the PBI (F = 4.617; P = 0.017) and the PD (F = 3.203; P = 0.044) value. In the patients in the OCT group, a more pronounced decrease in the PBI and PD was noted at 1-month follow-up as well as a greater increase in the PD value 3 months upon treatment completion. In the OCT group, no more atypical microorganisms were detectable 1 month post-treatment, while in the control group they were found in 34.5% of patients. The periodontal therapy bears good results in HIV-positive patients. Additional administration of OCT contributes to the significant decline in the PBI and DS values and eliminates atypical microorganisms within 1 month post-treatment. However, more favourable results were not noted in the OCT group at the 3-month assessment. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Pulmonary hypertension is rare but is one of the complications that occur due to HIV infection. Symptoms of HIV-associated pulmonary arterial hypertension are often non-specific but the main symptom of the disease is dyspnea. In this cross-sectional study, we measured systolic pulmonary arterial pressure (SPAP) by echocardiographic methods among HIV-positive patients who received ART. This research is a descriptive, cross-sectional study of 170 HIV-positive patients that was conducted in Imam-Khomeini hospital, Tehran, Iran during 2011-2013. All patients regularly received antiretroviral therapy at least for recent 2 years. There were not any cardiopulmonary symptoms (cough, dyspnea, exertional fatigue and chest discomfort) in these patients. All participants underwent echocardiography to estimate SPAP. The participants comprised 108 males (63.5%) and 62 females (46.5%). The mean age of patients was 41 years old, and the mean duration of HIV infection was 5.5 years. The mean CD4 cell count was 401 cell/µl. The principal regimen of antiretroviral therapy included two nucleoside reverse transcriptase inhibitor (NRTI) and one non-nucleoside reverse transcriptase inhibitor (NNRTI) in the hospital. The mean of systolic pulmonary arterial pressure was 25 mmHg in the participants; 156 (93.4%) of them had SPAP ≤ 30 mmHg (normal), six (3.6%) had SPAP: 31-35 mmHg (borderline) and five (3%) had SPAP > 35 mmHg (pulmonary hypertension). Our results indicated a significant increase of pulmonary hypertension in asymptomatic HIV-positive patients that had no association with any other risk factor. Also, antiretroviral therapy was not a risk factor for pulmonary hypertension in this study.

To assess the efficacy of a medicated dressing in the socket on the healing after dental extractions in HIV positive patients. Forty HIV positive patients with CD4 counts below 200 cells/mm(3) who were to have molar teeth extracted were randomly allocated to have the socket dressed with a medicated paste (Rifocort) with camphorated parachlorophenol and iodoform) and sutured (treated group), or merely sutured (control group). The sockets in the treated group healed more quickly than in the control group.

Patients with human immunodeficiency virus (HIV) infection have been reported to have parotid swellings of various types such as diffuse infiltrative lymphocytosis syndrome, parotitis, intraparotid lymphadenopathy, benign lymphoepithelial cyst (BLEC), as well as salivary gland neoplasms such as adenoid cystic carcinoma, Kaposi sarcoma and lymphoma. LECs in the parotid gland are uncommon benign entities with increased incidence associated with HIV infection. We are presenting a case of 28-year-old HIV-positive patient with BLECs in the parotid and submandibular glands. PMID:26097320

Kaposi's sarcoma (KS) and tuberculosis (TB) commonly cause pleural effusions in high human immunodeficiency virus (HIV) burden resource-limited countries. Differentiating between them is challenging, as pleural biopsy and TB culture are rarely available. To identify markers to differentiate between TB effusions and KS effusions in HIV-positive patients, and to compare liquid culture and Xpert MTB/RIF in pleural fluid. Fifty HIV-positive patients with pleural effusions recruited in Malawi underwent pleural ultrasound and aspiration. Fluid visual inspection, cell count, bacterial culture, glucose/protein, solid and liquid TB culture and Xpert were performed. The mean age of the patients was 32 years; 30/50 (60%) were male and 29 (58%) had cutaneous/oral KS. Thirteen (26%) pleural fluid samples were liquid culture-positive for TB, while 9/13 (69%) were Xpert-positive. Three (10.3%) KS patients had culture-positive TB effusions; 17 (58.6%) had KS effusions. The relative risk of TB in KS patients increased with limited KS, loculated fluid and low glucose. Eleven (52.3%) non-KS patients had culture-positive TB effusions associated with male sex, straw-coloured fluid and fibrin stranding on ultrasound. KS patients were most likely to have KS effusion, but TB should be considered. Most non-KS patients had TB, supporting the use of World Health Organization guidelines. Xpert identified two thirds of liquid culture-positive results.

Federal HIV prevention strategy seeks to increase efforts by health care providers to identify and reduce their HIV-positive patients’ transmission-related behaviors. Implementation of these recommendations will be hindered if providers perceive these efforts have the potential to harm their relationships with patients. Because transmission-related behaviors (unsafe sex and sharing needles) and the related issues of drug and alcohol use also jeopardize the health of HIV-positive patients, providers can use patient-centered counseling when addressing those behaviors. We suggest efforts to increase provider-delivered transmission-prevention counseling be reframed so that “prevention with positives” includes the goal of protecting HIV-positive patients’ health. We review the specific consequences of these risky behaviors on HIV-positive patients’ health and review brief counseling strategies appropriate for HIV care providers. PMID:16426152

Chronic kidney disease (CKD) is associated with increased all-cause mortality and kidney disease progression. Decreased kidney function at baseline may identify human immunodeficiency virus (HIV)-positive patients at increased risk of death and kidney disease progression. Observational cohort study. 7 large HIV cohorts in the United Kingdom with kidney function data available for 20,132 patients. Baseline estimated glomerular filtration rate (eGFR). Death and progression to stages 4-5 CKD (eGFR <30 mL/min/1.73 m(2) for >3 months) in Cox proportional hazards and competing-risk regression models. Median age at baseline was 34 (25th-75th percentile, 30-40) years, median CD4 cell count was 350 (25th-75th percentile, 208-520) cells/μL, and median eGFR was 100 (25th-75th percentile, 87-112) mL/min/1.73 m(2). Patients were followed up for a median of 5.3 (25th-75th percentile, 2.0-8.9) years, during which 1,820 died and 56 progressed to stages 4-5 CKD. A U-shaped relationship between baseline eGFR and mortality was observed. After adjustment for potential confounders, eGFRs <45 and >105 mL/min/1.73 m(2) remained associated significantly with increased risk of death. Baseline eGFR <90 mL/min/1.73 m(2) was associated with increased risk of kidney disease progression, with the highest incidence rates of stages 4-5 CKD (>3 events/100 person-years) observed in black patients with eGFR of 30-59 mL/min/1.73 m(2) and those of white/other ethnicity with eGFR of 30-44 mL/min/1.73 m(2). The relatively small numbers of patients with decreased eGFR at baseline and low rates of progression to stages 4-5 CKD and lack of data for diabetes, hypertension, and proteinuria. Although stages 4-5 CKD were uncommon in this cohort, baseline eGFR allowed the identification of patients at increased risk of death and at greatest risk of kidney disease progression.

HIV-positive patients must strictly adhere to antiretroviral regimens for the medications to work properly. Little, however, is known about the obstacles that patients face in adhering to the regimens or what, if anything, helps patients to adhere. The goals of the project were to describe, from HIV-positive patients' own perspectives, the barriers they face in adhering to antiretroviral regimens and the strategies they use to maximize their adherence. Five main barriers (forgetfulness, social/physical environment, complexity of the regimens, medication side effects, and inadequate patient knowledge) to adherence and six main facilitators (mechanical devices, "making a commitment," "routinizing," health beliefs, social support, and professional support) emerged from the data. Patients may overcome some of these barriers by receiving better health education about the need for adherence, professional and lay support for their efforts, and mechanical devices such as alarm clocks and medi-sets. Other barriers, however, such as the complexity of the medications, highlight the need for simplified antiretroviral regimens.

Human immunodeficiency virus (HIV)-positive patients suffer from a unique set of aesthetic challenges, frequently requiring plastic and reconstructive surgical intervention. This study was designed to evaluate the overall wound infection rates for elective surgery in this patient population, focusing specifically on differences between transdermal (both open and minimally invasive) and transoral procedures. Charts were reviewed for all patients with an International Classification of Diseases, Ninth Edition code of V08 (asymptomatic HIV infection, CD4 count >200 cells/microl) who underwent surgery by the senior author (S.P.D.) at this tertiary care hospital between January 1, 2000, and October 1, 2007 (39 patients, 98 procedures). Indication for surgery, type of procedure performed, wound infection rates, length of follow-up, status of HIV infection, and HIV treatment status were all documented. Data were collected according to internal review board protocol. Infection rates were compared between study groups and with the existing surgical literature. Statistical analysis revealed no significant difference in wound infection rate between open and minimally invasive procedures when a transdermal approach is used (10 percent and 0 percent, respectively; p > 0.05). However, there was a significantly increased infection rate in transoral surgery when compared with these two groups (71 percent; p < 0.001). These findings indicate that there is a greatly increased risk of wound infections for HIV-positive patients undergoing transoral surgery when compared with transdermal surgery and historical norms.

A 29 year old female HIV-positive patient presented in emergency with acute right lower quadrant abdominal pain, fever, tenderness and positive Blumberg sign. Laboratorial tests revealed eosinophilia, anaemia and leukocytosis. She underwent exploratory laparotomy followed by appendectomy. The pathological analysis of the appendix revealed acute appendicitis, accentuated eosinophilia and infestation by Strongyloides stercoralis and Enterobius vermicularis. She did well after surgery and adequate treatment. To the authors’ knowledge, this is the first case of eosinophilic acute appendicitis caused by these two parasitic worms reported in the medical literature. PMID:22605801

This article examines the legal and ethical issues that surround the confidentiality of medical records, particularly in relation to patients who are HIV positive. It records some historical background of the HIV epidemic, and considers the relative risks of transmission of HIV from individual to individual. It explains the law as it pertains to confidentiality, and reports the professional guidance in these matters. It then considers how these relate to HIV-positive individuals in particular.

A public referral hospital in Sao Paulo, Brazil. To evaluate chest physiotherapy as a means of obtaining sputum samples from human immunodeficiency virus (HIV) positive in-patients suspected of having pulmonary tuberculosis (TB). A prospective study. Five consecutive samples were collected from 132 patients using the 'spontaneous' technique (ST) on day 1, slow expiration with the glottis open in a lateral posture ('expiration lente totale glotte ouverte en infralatéral', ELTGOL) on day 2, ST on day 3, sputum induction with hypertonic saline (SIHS) on day 4 and ST on day 5. Samples were processed for acid-fast bacilli (AFB) smear and seeded onto Löwenstein-Jensen medium. Mycobacteria were recovered from 34 patients (25.8%). Nine (26.5%) of the strains were identified as mycobacteria other than Mycobacterium tuberculosis. AFB smear sensitivity was higher in ELTGOL samples than in ST or SIHS samples (52.9% vs. 32.4% and 29.4%), although the difference among the three was not significant (P = 0.098). In culture, the three ST samples proved significantly more sensitive (P = 0.05). Physiotherapy shows promise as a technique for obtaining sputum from HIV-positive patients, and AFB testing of a single sample presents high sensitivity. However, this does not preclude the routine collection of three samples, as TB cannot be ruled out before the culture results are known.

The objective of this cross-sectional study was to assess the nutritional status of HIV-positive patients in a hospital in the city of Niteroi, Rio de Janeiro, Brazil. We studied 235 patients (130 men and 105 women) from May 2009 to June 2010. The frequency of undernourishment among women was 7.6%; 26.7% of the women were overweight, and 16.2% were obese. Among men, the frequency of undernourishment was 3.8%; 25.4% of the men were overweight, and 6.9% were obese. A logistic regression was done to investigate the relationship between nutritional status and potential predisposing factors. Women were more frequently affected by obesity and undernourishment than men. However, only the difference in obesity was significant, and women had almost three times higher odds of being obese (OR 2.6; 95% CI 1.03-6.65). According to a nationwide survey done in Brazil during 2008-2009, 50.1% of the Brazilian healthy males were overweight, and 12.5% were obese; 48% of healthy females were overweight, and 16.9% were obese. Although the prevalence of undernourishment in HIV-positive patients is now lower than that observed in the beginning of the AIDS epidemic and excess weight is increasingly common among people living with HIV/AIDS, the proportion of excess weight was found lower and of undernourishment was higher in the present study than that found in the Brazilian population.

Introduction: It is important for HIV positive patients to be engaged in their care and be adherent to treatment in order to reduce disease progression and mortality. Studies found that illness representations influence adherence through the mediating role of coping behaviors. However, no study has ever tested if patient engagement to the visits mediate the relationship between illness perceptions and adherence. This study aimed to explore illness representations of HIV positive patients and test the hypothesis that illness representations predict adherence through the mediating role of a component of behavioral engagement. Methods: HIV-positive patients treated with highly active antiretroviral therapy (HAART) for at least one year and presenting to a check-up visit were eligible to participate in the study. Patients completed the Illness Perception Questionnaire-Revised. Behavioral engagement was measured based on the patients' clinical attendance to the check-up visits; adherence to HAART was measured by viral load. Undetectable viral load or HIV-RNA < 40 copies/ml were considered indexes of virologic success. Results: A total of 161 patients participated in the study. Most of them coherently attributed the experienced symptoms to HIV/HAART; perceived their condition as chronic, stable, coherent, judged the therapy as effective, and attributed their disease to the HIV virus and to their behavior or bad luck. The majority of patients (80.1%) regularly attended check-up visits and 88.5% of them reached virologic success. The mediation model did not show good fit indexes. However, a significant direct effect of two independent variables on virologic success was found. Specifically, the perception that the disease does not have serious consequences on patient's life and the prevalence of negative emotions toward HIV were associated with virologic success. On the contrary, the patient's perception that the disease has serious consequences on his/her life and the

Syphilis is an infection frequently seen with HIV, and European guidelines on the management of syphilis suggest that HIV-infected patients may have an increased risk of early neurological involvement, sometimes asymptomatic. Recent study shows a relationship between neurosyphilis and cerebrospinal fluid (CSF) HIV viral load (VL), which in turn may be associated with subsequent neurocognitive decline. The aim of the study was estimation of the frequency of neurosyphilis among HIV-positive patients with early syphilis. The study included all patients diagnosed with early syphilis who had lumbar puncture performed in the years 2008-2012. Analysis included CSF parameters (serology, mononuclear cells, protein, glucose, chloride and lactate levels), CD4 count, serum VL and highly active antiretroviral therapy (HAART). Diagnosis of neurosyphilis was confirmed by CSF serology [positive fluorescent treponemal antibody and/or Venereal Disease Research Laboratory (VDRL) test(s)] and increased number of mononuclear cells. Statistical analysis included χ(2) tests with an accepted significance level of P < 0.05. Lumbar puncture was performed in 72 patients, all men, with median age 33 (interquartile range 11) years. Neurosyphilis was confirmed in 65 (90.28%) of the patients. No statistically significant association between CSF parameters and CD4 count was found. However, statistically significant associations were found only between pleocytosis and serum VL > 1000 HIV-1 RNA copies/mL (P = 0.0451), as well as HAART treatment (P = 0.0328). The proportion of confirmed neurosyphilis cases, also in patients with low serum VDRL titres, was very high. Considering the high proportion of patients who objected to having LP performed in the absence of neurological symptoms and the risk associated with this procedure, it may be preferable to use treatments with good CNS penetration in all HIV-positive patients with early syphilis. © 2015 British HIV Association.

OBJECTIVES--To study the presentation and survival of patients who present with their first diagnosis of being HIV positive at the same time as their AIDS defining illness. DESIGN--Retrospective study of patients presenting with AIDS between 1991 and 1993. SETTING--Department of genitourinary medicine, St Mary's Hospital, London. MAIN OUTCOME MEASURES--AIDS defining illness at presentation and survival after diagnosis of AIDS. RESULTS--Between January 1991 and December 1993, 97 out of 436 patients (22%) presented with their first AIDS defining illness coincident with their first positive result of an HIV test (group B). The remaining 339 patients (78%) had tested positive for HIV-1 infection within the previous eight years and had consequently been followed up in clinics before developing their first AIDS defining illness (group A). The two groups of patients did not differ in age and sex distribution, risk factors for HIV-1 infection, nationality, country of origin, or haematological variables determined at the time of the AIDS defining illness. However, the defining illnesses differed between the two groups. Illnesses associated with severe immunodeficiency (the wasting syndrome, cryptosporidiosis, and cytomegalovirus infection) were seen almost exclusively in group A whereas extrapulmonary tuberculosis and Pneumocystis carinii pneumonia were more common in group B. The survival of patients in group B after the onset of AIDS was significantly longer than that of patients in group A as determined by Kaplan-Meier log rank analysis (P = 0.0026). CONCLUSIONS--Subjects who are HIV positive and present late are a challenge to the control of the spread of HIV infection because they progress from asymptomatic HIV infection to AIDS without receiving health care. The finding that presentation with an AIDS defining illness coincident with a positive result in an HIV test did not have a detrimental effect on survival gives insights into the effects of medical intervention on

Introduction Specific environmental factors may play a role in the development of Pneumocystis pneumonia (PCP) in HIV-positive patients. The aim of this study was to estimate the PCP incidence and mortality in hospitalized HIV-positive patients in Spain during the combination antiretroviral therapy (cART) era (1997 to 2011), as well as to analyze the climatological factors and air pollution levels in relation to hospital admissions and deaths. Methods We carried out a retrospective study. Data were collected from the National Hospital Discharge Database and the State Meteorological Agency of Spain. A case-crossover analysis was applied to identify environmental risk factors related to hospitalizations and deaths. For each patient, climatic factors and pollution levels were assigned based on readings from the nearest meteorological station to his or her postal code. Results There were 13,139 new PCP diagnoses and 1754 deaths in hospitalized HIV-positive patients from 1997 to 2011. The PCP incidence (events per 1000 person-years) dropped from 11.6 in 1997 to 2000, to 5.4 in 2004 to 2011 (p<0.001). The mortality (events per 10,000 person-years) also decreased from 14.3 in 1997 to 2000, to 7.5 in 2004 to 2011 (p<0.001). Most hospital admissions and deaths occurred in the winter season and the fewest occurred in the summer, overlapping respectively with the lowest and highest temperatures of the year in Spain. Moreover, lower temperatures prior to PCP admission, as well as higher concentrations of NO2 and particulate matter up to 10 m in size (PM10) at the time of admission were associated with higher likelihoods of hospital admission due to PCP when two weeks, one month, 1.5 months or two months were used as controls (p<0.01). Furthermore, higher concentrations of ozone at one month (p=0.007), 1.5 months (p<0.001) and two months (p=0.006) prior to admission were associated with higher likelihoods of hospital admission with PCP. For PCP-related deaths, lower

Introduction Diarrhea is a common complication of acquired immune deficiency syndrome (AIDS), occurring in almost 90% of AIDS patients in developing countries like India. The present study was aimed to determine the prevalence and microbiological profile of pathogens associated with diarrhea in human immunodeficiency virus (HIV) positive patients and their relation to CD4 counts. Materials and methods Forty-five successive HIV-positive patients, 27 with diarrhea (study group) and 18 without diarrhea (control group), were included in the three-month study. The HIV infection was confirmed by three different antibody detection tests. The stool samples were collected on two consecutive days and were examined for parasites by microscopy using wet mount and modified Ziehl-Neelsen stain. They were examined for bacteria by Gram stain and conventional Ziehl-Neelsen stain and were inoculated on appropriate culture media. The isolates were identified by standard biochemical tests, followed by antibiotic susceptibility testing using the Kirby-Bauer disc diffusion method. Results Twenty-four pathogens were detected in diarrheal HIV-positive patients, including 14 parasites (58.33%), seven bacteria (29.17%), and three fungi (12.50%). Isospora sp. was the most common parasite (25.9%) followed by Cryptosporidium sp. (14.8%). Other parasites included Cyclospora sp., Strongyloides stercoralis, and Entamoeba histolytica (3.7% each). Escherichia coli (18.5%) was the most common bacterial isolate, of which, 80% were Enterotoxigenic E. coli (ETEC) while 20% were Enteropathogenic E. coli (EPEC). Other isolates included Shigella flexneri and Mycobacterium tuberculosis (3.7% each). The isolates were sensitive to furazolidone (94.11%), chloramphenicol (76.47%), and gentamicin (52.94%). The isolates from diarrheal patients showed resistance to norfloxacin (5.88% vs. 50%, p<0.05) as compared to those from non-diarrheal patients. The diarrheal HIV-positive patients

AIM--Since most forms of Kaposi sarcoma are much more common in men than in women, the aim of this study was to examine serum concentrations of sex steroids in HIV positive men with and without Kaposi sarcoma. METHODS--Blood samples from 34 HIV positive men without Kaposi sarcoma (KS-) and 28 with Kaposi sarcoma (KS+) and from 35 HIV negative men (controls) were analysed for adrenal and gonadal steroids. Further analysis was done in subgroups classified by CD4 lymphocyte counts. RESULTS--KS+ patients had significantly higher serum dehydroepiandrosterone (DHEA) and testosterone concentrations than the KS- patients, and their DHEA, DHEA sulphate, testosterone, and androstenedione values were higher than in the controls. The KS+ patients with more than 500 CD4 lymphocytes per mm3 had significantly higher serum DHEA, DHEA sulphate, and testosterone than the KS- patients with the same CD4 counts; those with 500-200 CD4 cells/mm3 had higher serum DHEA and testosterone than the equivalent KS- men; and those with < 200 CD4 cells/mm3 had raised DHEA only compared with KS- men. Both KS+ and KS- men had higher serum progesterone and oestradiol than the controls. Glucocorticoids were not significantly altered. CONCLUSIONS--The high androgen levels in KS+ patients, particularly in the early stages of the disease (> 500 CD4 cells/mm3), may affect the immune system by inducing an abnormal cytokine profile, or by increasing T8 proliferation and activation, or both. This raises the question of the relationship between androgens and Kaposi sarcoma. PMID:7665693

More than 1 million individuals in the United States are HIV positive, with greater than 40,000 new patients being diagnosed per year. With the advent of highly active antiretroviral therapy (HAART), HIV-infected patients in the United States are living longer. HIV-infected patients receiving HAART now more commonly have noninfectious and nonopportunistic complications of their disease. This review article will discuss the assessment and treatment of HIV-positive patients in the era of HAART, with an emphasis on the noninfectious and changing infectious complications that require emergency care.

Strongyloides stercoralis, a nematode parasite in human with free living and autoinfective cycles, is often an asymptomatic infection of the upper small intestine. If the host becomes immunocompromised, autoinfection may increase the intestinal worm burden and lead to disseminated strongyloidiasis. We report a case of a 33 year old male HIV positive patient admitted on 2/6/08 in male medical ward, Regional Institute of Medical Sciences, Imphal, Manipur with complaints of loose stools, pain abdomen, nausea, vomiting, generalized weakness, loss of appetite and loss of weight for past one month with fever off and on. Stool examination reveals larvae of Strongyloides stercoralis. The patient was successfully treated with Ivermectin 200 microgm/kg daily for 2 days.

Importance Mobile teledermatology may increase access to care. Objective To determine if mobile teledermatology in HIV positive patients in Gaborone, Botswana was reliable and produced valid consultations in comparison to face-to-face dermatology consultations. Design Cross-sectional study Setting Outpatient clinics and public inpatient settings in Botswana. Participants 76 HIV positive patients aged 18 years and up with a skin or mucosal complaint that had not been previously evaluated by a dermatologist. Main Outcome(s) and Measure(s) We calculated Cohen's kappa coefficient for diagnosis, diagnostic category and management for test-retest reliability and for inter-rater reliability. We also calculated sensitivity and specificity for each diagnosis. Results Cohen's kappa for test-retest reliability ranged from 0.47 (95% CI 0.35-0.59) to 0.78 (95% CI 0.67-0.88) for the primary diagnosis, 0.29 (95% CI 0.18-0.42) to 0.73 (95% CI 0.61-0.84) for diagnostic category, and 0.17 (95% CI -0.01-0.36) to 0.54 (95% CI 0.38-0.70) for management. Cohen's kappa for inter-rater reliability ranged from 0.41 (95% CI 0.31-0.52) to 0.51 (95% CI 0.41-0.61) for the primary diagnosis, from 0.22 (95% CI 0.14-0.31) to 0.43 (95% CI 0.34-0.53) for the diagnostic category for the primary diagnosis and from 0.08 (95% CI 0.02-0.15) to 0.12 (95% CI 0.01-0.23) for management. Sensitivity and specificity for the top ten diagnoses ranged from 0 to 0.88 and from 0.84 to 1 respectively. Conclusions and Relevance Our results suggest that while the use of mobile teledermatology technology in HIV-positive patients in Botswana has significant potential for improving access to care, additional work is needed to improve reliability and validity of this technology on a larger scale in this population.

ABSTRACT The objective of this cross-sectional study was to assess the nutritional status of HIV-positive patients in a hospital in the city of Niterói, Rio de Janeiro, Brazil. We studied 235 patients (130 men and 105 women) from May 2009 to June 2010. The frequency of undernourishment among women was 7.6%; 26.7% of the women were overweight, and 16.2% were obese. Among men, the frequency of undernourishment was 3.8%; 25.4% of the men were overweight, and 6.9% were obese. A logistic regression was done to investigate the relationship between nutritional status and potential predisposing factors. Women were more frequently affected by obesity and undernourishment than men. However, only the difference in obesity was significant, and women had almost three times higher odds of being obese (OR 2.6; 95% CI 1.03-6.65). According to a nationwide survey done in Brazil during 2008-2009, 50.1% of the Brazilian healthy males were overweight, and 12.5% were obese; 48% of healthy females were overweight, and 16.9% were obese. Although the prevalence of undernourishment in HIV-positive patients is now lower than that observed in the beginning of the AIDS epidemic and excess weight is increasingly common among people living with HIV/AIDS, the proportion of excess weight was found lower and of undernourishment was higher in the present study than that found in the Brazilian population.

We investigated the relationships among gender, drug use, and perceived social support in 176 HIV positive patients recruited with their informal caregivers in HIV clinics. Perceived caregiver support, emotional support, tangible support, and conflict were assessed. Current drug use was defined as heroin and/or cocaine use within 6 months prior to baseline. Gender was not significantly associated with any of the four outcomes. Current drug users reported significantly higher conflict in social relationships than nonusers, but was not significantly associated with the other three outcomes. However, significant heroin/cocaine use by gender interactions were observed; specifically, the negative associations between current drug use and perceived caregiver and emotional support were stronger among females than males. We concluded that recent heroin/cocaine use may be associated with dissatisfaction in perceived social support from most sources, with the strongest relationships amongst drug using females.

The aim of this investigation was to establish the frequency of detection of periodontopathic bacteria and Gram-negative enteric rods in HIV-positive (HIV+) patients with periodontitis. Clinical parameters and microbiological samples were obtained from 31 HIV+ periodontitis (H+PG) patients, 32 HIV-negative (HIV-) periodontitis (H-PG) patients and 32 systemically and periodontally healthy (CG) patients. Microbial samples were analyzed using culturing techniques for periodontopathic and superinfecting microorganisms. The ANOVA test was used to assess differences in the clinical parameters, and the Chi square and two-tailed Mann Whitney tests were used to find differences in the composition of the microbiota (p < 0.05). The frequency of detection of periodontopathic bacteria was higher in HIV- periodontitis patients (p < 0.05) compared to HIV+ and healthy subjects. In contrast, HIV+ patients harbor higher levels of superinfecting microorganisms (p < 0.05). Pseudomonas aeruginosa, Enterobacter cloacae and Klebsiella pneumoniae were identified. The frequency of detection and levels of periodontopathic bacteria were higher in the HIV- periodontitis patients compared to HIV+ patients and healthy subjects. In contrast, levels of superinfecting bacteria were found to be elevated in HIV+ periodontitis patients. Special attention should be paid to the presence of periodontopathic and superinfecting bacteria in these patients in order to avoid further periodontal and systemic complications.

Background. In the medical sense, stigma has been defined as the collection of negative attitudes and beliefs that are directed at people living with a particular condition or disease process. A cohort study was conducted to explore the HIV stigma that is perceived by HIV-positive individuals versus that perceived by the general population within a community-based dental clinic. Methods. Two separate and independent cross-sectional surveys, the Berger Stigma Scale and the Rutgers-Modified Berger Stigma Scale, were employed in order to analyze the stigma factors of an HIV-positive population versus an HIV-negative general population, respectively. The HIV stigma factors studied included personalized stigma, disclosure concerns, negative self-image, and concern with public attitudes. Results. The total stigma scale scores for the studied HIV-positive population were significantly lower than the total stigma scale scores for the studied HIV-negative population (P < 0.05). Conclusion. Interestingly, there is a misplaced expectation by the general population that HIV-positive individuals experience more stigma than the HIV-positive population in the clinic actually reported. Interventions to reduce HIV stigma should be an integral component of comprehensive care for all patients. PMID:28096954

Objectives This study aimed to describe the epidemiology and risk factors of cholelithiasis and nephrolithiasis among HIV-positive patients in the era of combination antiretroviral therapy. Methods We retrospectively reviewed the medical records of HIV-positive patients who underwent routine abdominal sonography for chronic viral hepatitis, fatty liver, or elevated aminotransferases between January 2004 and January 2015. Therapeutic drug monitoring of plasma concentrations of atazanavir was performed and genetic polymorphisms, including UDP-glucuronosyltransferase (UGT) 1A1*28 and multidrug resistance gene 1 (MDR1) G2677T/A, were determined in a subgroup of patients who received ritonavir-boosted or unboosted atazanavir-containing combination antiretroviral therapy. Information on demographics, clinical characteristics, and laboratory testing were collected and analyzed. Results During the 11-year study period, 910 patients who underwent routine abdominal sonography were included for analysis. The patients were mostly male (96.9%) with a mean age of 42.2 years and mean body-mass index of 22.9 kg/m2 and 85.8% being on antiretroviral therapy. The anchor antiretroviral agents included non-nucleoside reverse-transcriptase inhibitors (49.3%), unboosted atazanavir (34.4%), ritonavir-boosted lopinavir (20.4%), and ritonavir-boosted atazanavir (5.5%). The overall prevalence of cholelithiasis and nephrolithiasis was 12.5% and 8.2%, respectively. Among 680 antiretroviral-experienced patients with both baseline and follow-up sonography, the crude incidence of cholelithiasis and nephrolithiasis was 4.3% and 3.7%, respectively. In multivariate analysis, the independent factors associated with incident cholelithiasis were exposure to ritonavir-boosted atazanavir for >2 years (adjusted odds ratio [AOR], 6.29; 95% confidence interval [CI], 1.12–35.16) and older age (AOR, 1.04; 95% CI, 1.00–1.09). The positive association between duration of exposure to ritonavir

PURPOSE: The primary endpoint of this study was to determine the prevalence of herbal product use by a sample of Mexican-American patients in the El Paso, TX region. Even though medicinal plants are popularly assumed to be a safe and natural alternative to conventional medications, some herbal products may pose a potential health risk to the consumer. Currently, there are few studies related to herbal use by Mexican Americans and none in HIV patients living on the U.S./México border. METHODS: A prospective observational study was conducted in hospitals and clinics throughout the El Paso region area. A semistructured interview was conducted by trained bilingual interviewers. A 45-item bilingual questionnaire was used to collect the information. RESULTS: A total of 439 non-HIV patients as well as 35 patients afflicted with HIV participated in the study. Seventy-nine percent (347/439) of non-HIV and 71% (25/35) of HIV patients reported using herbal products. The percentages of herbal use among the two groups did not show any statistically significant differences (p=0.29), and both groups reflected that herbal products are commonly used. CONCLUSIONS: The use of herbal products was very common among non-HIV (79%) and HIV-positive (71%) Mexican-Americans patients in the El Paso region. PMID:16396061

Patients infected with human immunodeficiency virus (HIV) usually develop some form of ocular complication in the different segments of the eye due to immune deficiency. In Ghana, data regarding ocular complications among HIV/AIDS patients is scarce. This study investigated the occurrence of ocular complications in HIV infected patients undergoing antiretroviral therapy at the Agogo Presbyterian Hospital in the Ashanti Region of Ghana. Blood samples were taken from 100 confirmed HIV infected patients. The CD4 + T cell count and WHO clinical staging were determined. The patients were taken through thorough ophthalmic assessments to determine any ocular complications. Forty-eight patients (48 %) had at least one HIV-related ocular complication. These complications occurred more frequently among those with CD4 counts below 200 cells/μL. Of the participants with HIV-related ocular complications, 11 (23 %) had retinal microvasculopathy, 10 (21 %) showed allergic conjunctivitis, 7 (15 %) had HIV retinopathy and 7 (15 %) had conjunctival carcinoma. All the participants in the study were on first-line antiretroviral therapy; 68 % were females and 72 % were in the Stage 3 of the WHO Clinical Staging of HIV infection. The prevalence of ocular complications in HIV positive persons under treatment in Ghana is high. Lower CD4 + T cell counts coupled with age were predisposing factors to HIV-related ocular complications.

HIV has been known to interfere with the natural history of hepatitis B virus (HBV) infection. In this study we investigate the prevalence of occult hepatitis B virus infection (OBI) among HIV-infected individuals in Nigeria. Overall, 1200 archived HIV positive samples were screened for detectable HBsAg using rapid technique, in Ikole Ekiti Specialist Hospital. The HBsAg negative samples were tested for HBsAg, anti-HBc, and anti-HCV by ELISA. Polymerase chain reaction was used for HBV DNA amplification and CD4 counts were analyzed by cytometry. Nine hundred and eighty of the HIV samples were HBsAg negative. HBV DNA was detected in 21/188 (11.2%) of patients without detectable HBsAg. CD4 count for the patients ranged from 2 to 2,140 cells/μL of blood (mean = 490 cells/μL of blood). HCV coinfection was detected only in 3/188 (1.6%) of the HIV-infected patients (P > 0.05). Twenty-eight (29.2%) of the 96 HIV samples screened were positive for anti-HBc. Averagely the HBV viral load was <50 copies/mL in the OBI samples examined by quantitative PCR. The prevalence of OBI was significantly high among HIV-infected patients. These findings highlight the significance of nucleic acid testing in HBV diagnosis in HIV patients. PMID:24868208

The purpose of this study was to determine the prevalence of fever of unknown origin (FUO) in a cohort of HIV positive patients and to describe their evolution and the final diagnosis. The clinical records of 412 patients followed from January 1987 to December 1990 at our HIV outpatient clinic were reviewed: in 151 patients 255 episodes of fever had been observed of which 22 (in 21 patients) met the criteria for FUO. 19 patients (90%) presented with a CDC/WHO stage IV HIV infection and the mean CD4+ lymphocyte count was 0.160 G/l. The etiology was ultimately determined in 13/22 episodes (3 Pneumocystis carinii pneumonia, 3 invasive infections due to atypical mycobacteria, 2 bacterial pneumonia, 1 Cytomegalovirus colitis, 1 Isospora belli enteritis, 1 visceral leishmania, 1 candida septicemia and 1 lymphoma). In 6/22 episodes, the fever subsided after zidovudine was started and was therefore attributed to HIV itself. In 3/22 episodes no etiology was found. In conclusion, this series shows that FUO is usually seen in advanced HIV infection and that it often represents an early sign of opportunistic infection. This observation underlines the importance of follow-up, since it finally served to detect the etiology of FUO in 86% of cases. Trial treatment with zidovudine can be useful where no pathology has been discovered despite 3 weeks' follow-up and appropriate investigations.

The incidence of anal cancer in human immunodeficiency virus (HIV)-positive individuals is increasing, and how co-infection affects outcomes is not fully understood. This study sought to describe the current outcome disparities between anal cancer patients with and without HIV undergoing abdominoperineal resection (APR). A retrospective review of all US patients diagnosed with anal squamous cell carcinoma, undergoing an APR, was performed. Cases were identified using a weighted derivative of the Healthcare Utilization Project's National Inpatient Sample (2000-2011). Patients greater than 60 years old were excluded after finding a skewed population distribution between those with and without HIV infection. Multivariable logistic regression and generalized linear modeling analysis examined factors associated with postoperative outcomes and cost. Perioperative complications, in-hospital mortality, length of hospital stay, and hospital costs were compared for those undergoing APR with and without HIV infection. A total of 1725 patients diagnosed with anal squamous cell cancer undergoing APR were identified, of whom 308 (17.9 %) were HIV-positive. HIV-positive patients were younger than HIV-negative patients undergoing APR for anal cancer (median age 47 years old versus 51 years old, p < 0.001) and were more likely to be male (95.1 versus 30.6 %, p < 0.001). Postoperative hemorrhage was more frequent in the HIV-positive group (5.1 versus 1.5 %, p = 0.05). Mortality was low in both groups (0 % in HIV-positive versus 1.49 % in HIV-negative, p = 0.355), and length of stay (LOS) (10+ days; 75th percentile of patient data) was similar (36.9 % with HIV versus 29.8 % without HIV, p = 0.262). Greater hospitalization costs were associated with patients who experienced a complication. However, there was no difference in hospitalization costs seen between HIV-positive and HIV-negative patients (p = 0.66). HIV status is not associated with worse

Achieving linkage to care and viral suppression in human immunodeficiency virus (HIV)-positive patients improves their well-being and prevents new infections. Current gaps in the HIV care continuum substantially limit such benefits. To evaluate the effectiveness of financial incentives on linkage to care and viral suppression in HIV-positive patients. A large community-based clinical trial that randomized 37 HIV test and 39 HIV care sites in the Bronx, New York, and Washington, DC, to financial incentives or standard of care. Participants at financial incentive test sites who had positive test results for HIV received coupons redeemable for $125 cash-equivalent gift cards upon linkage to care. HIV-positive patients receiving antiretroviral therapy at financial incentive care sites received $70 gift cards quarterly, if virally suppressed. Linkage to care: proportion of HIV-positive persons at the test site who linked to care within 3 months, as indicated by CD4+ and/or viral load test results done at a care site. Viral suppression: proportion of established patients at HIV care sites with suppressed viral load (<400 copies/mL), assessed at each calendar quarter. Outcomes assessed through laboratory test results reported to the National HIV Surveillance System. A total of 1061 coupons were dispensed for linkage to care at 18 financial incentive test sites and 39 359 gift cards were dispensed to 9641 HIV-positive patients eligible for gift cards at 17 financial incentive care sites. Financial incentives did not increase linkage to care (adjusted odds ratio, 1.10; 95% CI, 0.73-1.67; P = .65). However, financial incentives significantly increased viral suppression. The overall proportion of patients with viral suppression was 3.8% higher (95% CI, 0.7%-6.8%; P = .01) at financial incentive sites compared with standard of care sites. Among patients not previously consistently virally suppressed, the proportion virally suppressed was 4.9% higher (95% CI, 1

Background Major depression can profoundly impact clinical and quality-of-life outcomes of people living with HIV, and this disease is underdiagnosed and undertreated in many HIV-positive individuals. Here, we describe the prevalence of publicly funded primary and secondary mental health service use and antidepressant use, as well as mental health care for depression in accordance with existing Canadian guidelines for HIV-positive patients with depression in Ontario, Canada. Methods We conducted a prospective cohort study linking data from the Ontario HIV Treatment Network Cohort Study with administrative health databases in the province of Ontario, Canada. Current depression was assessed using the Center for Epidemiologic Depression Scale or the Kessler Psychological Distress Scale. Multivariable regressions were used to characterize prevalence outcomes. Results Of 990 HIV-positive patients with depression, 493 (50%) patients used mental health services; 182 (18%) used primary services (general practitioners); 176 (18%) used secondary services (psychiatrists); and 135 (14%) used both. Antidepressants were used by 407 (39%) patients. Patients who identified as gay, lesbian, or bisexual, as having low income or educational attainment, or as non-native English speakers or immigrants to Canada were less likely to obtain care. Of 493 patients using mental health services, 250 (51%) received mental health care for depression in accordance with existing Canadian guidelines. Conclusions Our results showed gaps in delivering publicly funded mental health services to depressed HIV-positive patients and identified unequal access to these services, particularly among vulnerable groups. More effective mental health policies and better access to mental health services are required to address HIV-positive patient needs and reduce depression’s impact on their lives. PMID:27280751

There is a paucity of HIV autopsy data from South America and none that document the postmortem findings in patients with HIV/AIDS in Peru. The purpose of this autopsy study was to determine the spectrum of opportunistic infections and the causes of mortality in HIV-positive patients at a public hospital in Lima. Clinico-epidemiological information regarding HIV infection in Peru is also reviewed. Sixteen HIV-related hospital postmortems, performed between 1999 and 2004, were included in this retrospective analysis. The primary cause of death was established in 12 patients: one died of neoplasia and 11 of infectious diseases, including 3 from pulmonary infection, 7 from disseminated infection, and 2 from central nervous system infection (one case had dual pathology). Opportunistic infections were identified in 14 cases, comprising cytomegalovirus, histoplasmosis, cryptococcosis, toxoplasmosis, Pneumocystis pneumonia, aspergillosis, tuberculosis, varicella zoster virus, and cryptosporidiosis. Fourteen patients had at least one AIDS-related disease that had been neither clinically suspected nor diagnosed premortem. Moreover, 82% of the diagnoses considered to be of important clinical significance had not been suspected antemortem. The spectrum and frequency of certain opportunistic infections differed from other South American autopsy studies, highlighting the importance of performing HIV/AIDS postmortems in resource-limited countries where locally specific disease patterns may be observed.

Opportunistic infections were identified in 14 cases, comprising cytomegalovirus, histoplasmosis, cryptococcosis, toxoplasmosis, Pneumocystis pneumonia, aspergillosis, tuberculosis, varicella zoster virus, and cryptosporidiosis. Fourteen patients had at least one AIDS-related disease that had been neither clinically suspected nor diagnosed premortem. Moreover, 82% of the diagnoses considered to be of important clinical significance had not been suspected antemortem. The spectrum and frequency of certain opportunistic infections differed from other South American autopsy studies, highlighting the importance of performing HIV/AIDS postmortems in resource-limited countries where locally specific disease patterns may be observed.

Oropharyngeal candidiasis caused by various species of Candida is one of the most common infections in HIV seropositive or AIDS patients. Drug resistance among these yeasts is an increasing problem. We studied the frequency of resistance profile to fluconazole, itraconazole, ketoconazole, amphotericin B and terbinafine of 137 isolates of Candida sp. From HIV positive or AIDS patients with oropharyngeal candidiasis at Instituto de Inmunología, U.C.V. and the Hospital "Jose Ignacio Baldó", Caracas Venezuela, using the well diffusion susceptibility test (Magaldi et al.). We found that nearly 10% of C. albicans isolates were primarily fluconazole resistant, 45% of C. albicans isolates from patients with previous treatment were resistant to fluconazole, of which 93% showed cross-resistance to itraconazole, and even about 30% of C. tropicalis (n = 13) were resistant to fluconazole and/or itraconazole. To this respect, several recent reports have been described antifungal cross-resistance among azoles. Therefore, we consider that C. tropicalis should be added to the growing list of yeast in which antifungal drug resistance is common. This report could be useful for therapeutic aspect in AIDS patients with oral candidiasis.

We described a case of a 56 year old homosexual HIV positive man who presented a history of CSU since one year (2012). All the allergologic, immunologic and microbiologic tests to evaluate the pathogenesis of wheals resulted negative. Therefore in June 2015 we decided to start therapy with Omalizumab while the patient kept on effective antiretroviral therapy with 310 cells/mm3 TCD4 counts and undetectable HIV viremia. After two monthly subcutaneuous injection of 150 mg of Omalizumab the patient had no more urticarial symptoms. UAS7 (Urticaria Activity Score over 7 days) and Cu-Q2oL (chronic urticarial quality of life questionnaire) dropped respectively to 14 from 42 and to 0 from 40 with increase of TCD4 counts while viral load remained undetectable. In November 2015, i.e. 4 months after the end of Omalizumab therapy, the patient was still asymptomatic with persistent effective immune-virological response to antiretroviral therapy. This case report confirms the excellent tolerability and efficacy of anti-IgE therapy in the treatment of spontaneous chronic urticarial even in an immunodepressed patient for HIV infection. Omalizumab therapy shows a remarkable clinical success and had no effect on peripheral TCD4 counts and HIV viral load.

Robert Veatch has proposed a model of the doctor-patient relationship that has as its foundation the sharing of values between the doctor and the patient. This paper uses qualitative research conducted with six doctors involved in the long term, specialised care of HIV positive patients in South Australia to explore the practical application of Veatch's value sharing model in that setting. The research found that the doctors in this study linked "values" with sexual identity such that they defined value sharing, in part, as a shared set of values and beliefs about sexual identity and practices. They voluntarily identified themselves as either homosexual or heterosexual and they regarded the relation between their own sexual identity and that of their patients as important for the provision of quality care. None of the doctors thought that value sharing, in the way they defined it, was essential to the clinical relationship, but the homosexual doctors attributed a greater degree of importance to it than their heterosexual colleagues.

Introduction HIV infection is accompanied by a variety of neurological disorders. Depression of cell-mediated immunity is followed by the development of central nervous system opportunistic infections/tumours, and frequently by the occurrence of the AIDS dementia complex (ADC). However, the pathophysiology of the emergence of neuro-AIDS is still unknown. Despite the development of cognitive impairments, the early diagnosis, objectification and quantification of the existence and extent of this impairment during infection are difficult to recognize in each individual case. To support the early diagnosis of ADC, there is a need for additional, non-invasive diagnostic methods. In this study, it is of interest to answer the clinically relevant question of whether magnetic resonance spectroscopy can detect changes in the cerebral metabolism of asymptomatic HIV-positive patients and is possibly suitable for the early diagnosis and prevention of HIV encephalopathy. Methods A group of 13 asymptomatic, HIV-positive patients with combined antiretroviral therapy (cART) and 13 healthy controls were examined with 2D 1H-MRS and 3D 31P-MRS at 3T. The patients were treated with cART for at least 12 months. Changes in the absolute concentrations of phosphorylated metabolites (ATP), N-acetyl-aspartate, creatine, myo-Isonitol, glutamate/glutamine and choline-containing compounds were compared with that of control subjects. Results Asymptomatic HIV-positive patients had significantly lower N-acetyl-aspartate in the white matter in a frontal and parietal target region. The other evaluated metabolites in the 1H MRS showed no significant difference between the HIV-positive patients and healthy controls. The 31P-MRS detected significant elevated values regarding the choline-containing compounds PEth, GPE and PCho.

The aim of this paper is to describe a case report of EMP in an HIV-positive patient. A 44-year-old, dark-skinned HIV-infected woman was referred to the Oral Diseases Treatment Center with a swelling at palate and left gingival fornix in the maxilla. Biopsy was taken and the oral lesion was diagnosed as EMP with well-differentiated plasma cells and restriction of the lambda light-chain. Skeletal survey was performed and no radiograph alterations were observed, thus supporting the diagnosis of EMP. Patient was referred to treatment and after two months of chemo and radiotherapy, an expanding lesion was observed in L5/S1 patient's vertebrae. Biopsy of the spinal lesion was consistent with lymphoma with plasmocitary differentiation, supporting the diagnosis of multiple myeloma (MM). Regarding the medical history, the final diagnostic was an oral extramedullary plasmacytoma with rapid progression into multiple myeloma. It is crucial to emphasize the relevance of HIV infection as a risk factor for both aggressive clinical behavior and unusual clinical presentation of extramedullary plasmacytoma cases. PMID:27980867

This systematic literature review determined the strength of evidence regarding whether patients with human immunodeficiency virus, or HIV, are at higher risk of developing complications from invasive oral procedures than similar patients without HIV. MEDLINE and EMBASE searches of the English literature from the early 1980s through April 2000 yielded five articles meeting the inclusion and exclusion criteria: original research, concurrent treatment of HIV-positive and HIV-negative subjects, presence of complications (for example, local or systemic infection, bleeding, alveolitis, delayed healing) resulting from extractions, orthognathic surgery, periodontal therapy, endodontic therapy, placement of dental implants, prophylaxis, or scaling and root planing. The authors found no studies involving orthognathic surgery, periodontal therapy, dental implants, prophylaxis, or scaling and root planing, and only one study reporting few immediate endodontic therapeutic complications. Thus, the evidence is insufficient with respect to any additional risk associated with these procedures among people with HIV/AIDS. Because of the few studies, low overall complication rates and variability in results from different analytic approaches, the authors consider the evidence to be too poor to rule in or out a meaningful relationship between HIV status and complications from tooth extractions. Limited published scientific evidence is available to guide clinicians in regard to possible increased risks of invasive oral procedures associated with the HIV status of the patient.

To detect the presence of microsporidia and other enteric parasites in patients with HIVAIDS of the Autonomous Services University Hospital of Maracaibo (SAHUM), where there are no previous studies in this field. Fecal samples were analyzed by means of direct exam, concetration method with formal-ether, Kinyoun coloration and fast Gram-Chromotrope coloration. Separate PCR were perfomed to differentiate Entamoeba histolytica and Entamoeba dispar , when the E. histolytica/E. dispar complex was observed in the microscope. Information on the patient was obtained trough clinical history. Of 56 individuals that participated, 38 (67.86%) presented some commensal parasite and/ or pathogenic species in their fecal sample. Carriers of pathogenic species were predominat (26/38). Protozoa such as Isospora belli protozoa (17.65%), Blastocystis spp. (17.65%), Cryptosporidium spp. (7.84%), E. histolytica/E. dispar (5.88%), Entamoeba coli (3.92%), Giardia lamblia (3.92%), Endolimax nana (3.92%), Cyclospora cayetanensis (3.92%), and Chilomastix mesnilli (1.96%) were diagnosed. Among the helminths, Ascaris lumbricoides, Trichuris trichiura and Strongyloides stercoralis , had a percentage of 27.27% each, and Hymenolepis nana , 18.18%. Entamoeba histolytica was only detected in one of three cases presenting complex microscopic examination. By Gram-chromotrope, 17 samples showed spores of the Microsporidia phylum, equivalent to 33.33% prevalence. Microsporidia may be first prevalente in HIV positive patients when specific diagnostic techniques are used.

Background Ocular surface squamous neoplasia (OSSN) is becoming increasingly prevalent and aggressive in Sub-Saharan Africa. It is a phenomenon linked with human immunodeficiency virus (HIV) infection, although association rates in Angola are currently unknown. A topical treatment that is effective in HIV-positive and HIV-negative individuals may be preferable to surgery in some contexts. We aimed to estimate the proportion of OSSN associated with HIV in Angola and to report on the success of topical 5-fluorouracil as a primary treatment in HIV-positive and HIV-negative patients. Methods Photographs of OSSNs taken at presentation and following treatment with 5-fluorouracil in patients presenting to Boa Vista Eye Clinic, Angola, between October 2011 and July 2013 were grouped into HIV-positive and HIV-negative groups and analyzed to compare presenting features and treatment response. Eighty-one OSSNs were analyzed for clinical features and 24 met the inclusion criteria for analysis of treatment response. Results Eighty-two patients presented with OSSN between October 2011 and July 2013. Twenty-one (26%) were HIV-positive and typically had OSSNs that exhibited more pathological features than those in HIV-negative patients. Twenty-four (29%) patients met the inclusion criteria for analysis of treatment response; of these, 26 (91%) OSSNs in both groups displayed at least partial resolution after one treatment course. In the HIV-positive group, five of eight patients displayed complete resolution, two showed partial resolution, and one failed. In the HIV-negative group, five of 16 showed complete resolution, ten of 16 had partial resolution, and one failed. Conclusion Individuals presenting with OSSN in Angola are more likely to have HIV infection compared with the general population. Regardless of HIV status, 5-fluorouracil drops can be an effective strategy for management of OSSN without incurring the costs and risks of surgery in the developing world setting. PMID

Introduction: The widespread use of effective highly active antiretroviral therapy (HAART) in HIV patients has coincided with increasing reports of complications like HIV-associated lipodystrophy syndrome and the metabolic alterations, affecting the lipid and glucose metabolism. Evidences in support of lipodystrophy and dyslipidaemia associated with First- line HAART in our area is scarce. The aim of the present study was 1) to study and compare Lipid profile in HIV positive patients on ART with that of freshly diagnosed HIV positive patients who were yet to be started on ART. 2) To assess lipodystrophy syndrome in patients on ART. Materials and Methods: Hundred newly diagnosed HIV positive patients who were yet to be started on ART were taken as controls (ART-Naïve).Hundred randomly selected HIV+ patients who were already on First-line ART regimen (Stavudine/Zudovudine + Lamivudine + Nevirapine) for more than 12 months were taken as cases (ART). This study was conducted for a period of 12 months at the VIMS ART centre, Bellary, Karnataka, India. Results: There was a significant increase (p<0.001) in serum Total Cholesterol, LDL-C, TG, VLDL, Non-HDL -C & TC/HDL-C ratio in ART patients compared to ART-naïve patients. Of the 100 ART patients 23 had lipodystrophy syndrome (buffalo hump, abnormal fat deposition around neck & back, buccal fat resorption, increase in abdominal fat). Conclusion: To conclude, it is evident from our study that there is increase in lipid profile (except HDL) in ART patients compared to ART Naïve group and 23 ART patients showed lipodystrophy syndrome. Hence it appears reasonable to measure fasting lipid levels before and 3-6 months after antiretroviral therapy is initiated or when ART regimen is changed. PMID:25478335

Lipodystrophy is a side-effect associated with treatment for human immunodeficiency virus (HIV) and is found chiefly on the face (disappearance of buccal fat pads) and is detrimental to self-esteem. This was a retrospective study in HIV-positive patients with facial lipoatrophy treated between 1999 and 2004 by means of subcutaneous injections of polylactic acid (Newfill). We assessed the efficacy of treatment, the number of injections given, treatment methods and adverse effects. Eighty-three patients were treated between 1999 and 2004. Each patient received a mean of between 3 and 4 treatment sessions comprising subdermal injection of 1 ampoule of Newfill into each cheek. Ultrasound assessment of the dermis over the cheekbone was performed in 45 patients and showed an increase in dermal thickness of between 3 and 7 mm. Following injection, edema was observed in all cases and lasted between 1 and 2 days. Five patients presented bruising at the injection sites. Two patients presented asymmetry lasting 4 months and requiring correction. Four patients had non-inflammatory granulomas, which were not visible but were palpable in 2 cases; all nodules regressed after 4 months. Treatment of facial lipoatrophy in HIV patients by injection of polylactic acid (Newfill) was shown to be efficacious in the majority of subjects. Training in the administration of this treatment is needed to ensure optimal efficacy and safety. A number of technical difficulties led to changes in treatment methods, i.e. routine adoption of a mask and protective glasses and use of a Luer-lock syringe due to blockage of syringes in more than 20% of cases, with splashing; increase in dilution volume from 3 to 5 ml; use of a centrifuge to ensure greater homogeneity of the solution; use of lidocaine in place of water for injections in order to reduce pain for patients.

Our study assessed the influence of HIV-related stigma on treatment adherence among people living with HIV in Chiang Mai, Thailand, and whether social support had a moderating effect on this relationship. We recruited 128 patients living with HIV from Sansai Hospital, a community hospital in Chiang Mai, Thailand, and collected data through structured interviews. All forms of HIV-related stigma considered in this study (personalized experience, disclosure, negative self-image, and public attitudes) were negatively correlated with adherence to anti-retroviral regimens. Multiple linear regression indicated that total HIV-related stigma was more predictive of treatment adherence than any individual stigma type, after adjusting for socio-demographic and health characteristics. Tests of interaction showed that social support did not appear to moderate the association between HIV stigma and treatment adherence. Our findings suggest that community and government efforts to improve public perceptions about people living with HIV might promote treatment adherence behaviors among HIV-positive patients.

There are conflicting reports in literature about correlation of CSF viral RNA levels with neurological manifestations in HIV positive patients. Many studies in animals and human subjects have shown that CSF HIV-1 RNA can be useful as a specific marker of HIV induced neuropathology. To the contrary there are studies which show that neurological disease states can occur in absence of significant increase of CSF HIV RNA. This was a prospective study conducted at Base hospital Delhi Cantt, New Delhi, a tertiary care hospitals for HIV patients. The study period was from 16 May 2006 to16 Jun 2011. The current study included forty (40) patients (Twenty HIV positive patients with neurological manifestations and twenty HIV positive patients clinically without any neurological manifestation). All potential study subjects and controls were explained the nature of this study and enrolled thereafter with written consent. In our study all the cases (HIV/AIDS patients with Neuro AIDS) and controls (HIV/AIDS patients without Neuro manifestations) were males only. 45% of the cases and 60% of controls were in the age group of 25 to 35 yrs and 35 % of cases and 40% of controls were in age group of 36 to 45 yrs. Among cases (HIV patients with neurological manifestations), The neurological manifestations in our 20 patients included; dementia-5, cryptococcal meningitis-4, Tubercular meningitis-4, CVA-3, Headache-3, (without CSF abnormality), 1 case each of pyogenic meningitis, Candida meningitis, Tremors and Herpes Zoster. Among the 20 cases fourteen patients had abnormal CSF (70%) whereas only one patient among the controls showed CSF abnormality (5%). Out of 20 cases, radio-imaging (CT Scan/ MRI) of brain was done in 18 cases. Twelve cases (66.66) had some abnormality on CT/ MRI. Various abnormalities seen were as under Calcified granuloma-1, Infarcts-5, Hydrocephalus-2, TBM (meningeal enhancement)-2, Candidiasis (Focal hypodensities in subcortical white matter of cerebral

Context: The advancement and development of new drugs and treatment strategies increase the risk of unusual Adverse Events (AEs) in HIV patients. Aims: The objective of our study was to assess the incidence, types and nature of AEs in HIV positive subjects. Settings and Design: Patients with WHO stage IV disease irrespective of the CD4 cell count, or WHO stage III disease with a CD4 cell count <350 cell/cu. Mm, or, WHO stage I or II disease with a CD4 cell count of <200 cells/cu. mm, and on prior anti-retroviral therapy for not more than six months preceding the observation date, were included in the study. After initiation of therapy, the patients were examined for the occurrence any adverse events including the type and severity, or any other abnormal laboratory findings. Causality assessment of the adverse events was done using the Naranjo's scale. Results: Out of 327 patients studied prospectively, 43 patients developed AEs. Out of these, 23 (53.5%) were males and 20 (46.5%) were females. A total of 53 (16.21%) AEs were reported. Antitubercular drugs caused the maximum AEs (28.3%) followed by zidovudine (20.7%), nevirapine (15.0%) and efavirenz (5.6%). Stavudine, ethambutol, sulfamethoxazole and trimethoprim, and atazanavir were also responsible for 3.7% of AEs individually. Causality assessment done according to the Naranjo's scale revealed that 66.04% AEs were ‘probable’ and 33.96% were ‘possible’. Conclusions: Anemia, hepatitis and dermatological adverse effects are the most common AEs. Antitubercular drugs contributed significantly for the incidence of AEs in these patients. Frequency of AEs was slightly more in males compared to females. PMID:25657900

Oral hairy leukoplakia (OHL) is commonly found in individuals infected with HIV and represents the most frequent oral manifestation. The purpose of this study was to detect the presence of Human Papillomavirus (HPV) and Epstein Barr Virus (EBV) in OHL of HIV+ Venezuelan patients. We evaluated 21 HIV+ adult patients with clinically present OHL lesions: 11 under antiretroviral therapy, 10 without therapy, and 10 oral mucosal samples as controls. Nested-PCR was used to detect EBV and HPV infection. The INNO-LiPA HPV Genotyping v2 was applied to determine the HPV genotype. The EBV genome was found in 16/21 (76%) of the HIV+ patients with OHL. No difference was observed in EBV+ and EBV- patients related to antiretroviral therapy viral load and CD4+ Tcell coant. HPV-DNA was observed in 7/21 HIV positive cases (33%). The HPV genotypes detected were: 6, 11, 31, 33, 52, and 56/74. The most frequently HPV found was genotype 6 in 7/7, while two cases were HPV-11 and two HPV-52. Of the positive cases, 5/7 (71%) presented co-infection with more than one HPV genotype and 4/7 (57%) had HPV coinfection with high and low risk types. No case was EBV or HPV positive in the control group. In this study, a higher EBV prevalence was observed in OHL-HIV+ patients, confirming the etiologic role in this entity. A considerable number of cases were positive for HPV infection, and many patients presented coinfection with more than one HPV genotype as well as the presence of high oncogenic risk HPV in OHL.

Introduction While the care of HIV-positive patients, including the detection and management of comorbidities, has historically been provided in HIV specialist outpatient clinics, recent years have seen a greater involvement of non-HIV specialists and general practitioners (GPs). The aim of this study is to determine whether patients would prefer to see their GP or HIV physician given general symptoms, and to understand what aspects of care influence their preferences. Methods/analysis We have developed and piloted a discrete choice experiment (DCE) to better understand patients' preferences for care of non-HIV-related acute symptoms. The design of the DCE was informed by our exploratory research, including the findings of a systematic literature review and a qualitative study. Additional questionnaire items have been included to measure demographics, service use and experience of non-HIV illnesses and quality of life (EQ5D). We plan to recruit 1000 patients from 14 HIV clinics across South East England. Data will be analysed using random-effects logistic regression and latent class analysis. ORs and 95% CIs will be used to estimate the relative importance of each of the attribute levels. Latent class analysis will identify whether particular groups of people value the service attribute levels differently. Ethics/dissemination Ethical approval for this study was obtained from the Newcastle and North Tyneside Research Ethics Committee (reference number 14/NE/1193). The results will be disseminated at national and international conferences and peer-reviewed publications. A study report, written in plain English, will be made available to all participants. The Patient Advisory Group will develop a strategy for wider dissemination of the findings to patients and the public. PMID:27431895

This clinical trial evaluated a contingency management intervention designed to improve medication adherence among HIV-positive methadone maintenance patients. After a 4-week baseline observation phase, eligible participants (N=66) were randomly assigned to: (a) medication coaching sessions every other week to assist with adherence strategies (comparison group) or (b) medication coaching plus voucher reinforcement for opening electronic medication caps on time (voucher group). Baseline adherence (percent doses taken/percent total possible doses) was 51% using electronic measurement, 75% using self-report and 75% using pill count. The intervention was provided for 12 weeks, with a 4-week follow-up. The primary outcome results of the clinical trial indicated effectiveness during the intervention, with significant mean adherence differences between voucher and comparison groups using electronic measurement (78% versus 56%), pill count (86% versus 75%), and self-report (87% versus 69%). Differences between groups faded after vouchers were discontinued. Contingency management shows promise as a strategy to promote antiretroviral medication adherence in this population.

We conducted a cross-sectional study in 448 HIV positive patients attending five European outpatient clinics to determine prevalence of and factors associated with neurocognitive impairment (NCI) using computerized and pen-and-paper neuropsychological tests. NCI was defined as a normalized Z score ≤-1 in at least 2 out of 5 cognitive domains. Participants' mean age was 45.8 years; 84% male; 87% white; 56% university educated; median CD4 count 550 cells/mm(3); 89% on antiretroviral therapy. 156 (35%) participants had NCI, among whom 26 (17%; 5.8% overall) reported a decline in activities of daily living. Prevalence of NCI was lower in those always able to afford basic needs (adjusted prevalence ratio [aPR] 0.71, 95% confidence interval [CI] 0.54-0.94) or with a university education (aPR 0.72, 95% CI 0.54-0.97) and higher in those with severe depressive symptoms (aPR 1.53, 95% CI 1.09-2.14) or a significant comorbid condition (aPR 1.40, 95% CI 1.03-1.90).

Adherence to antiretroviral therapy is crucial to ensure viral suppression. In the scientific community it is widely accepted that an adherence level of at least 90% is necessary to achieve viral suppression. This study uses pharmacy refill records to describe antiretroviral adherence in HIV-positive patients in Ugu District, KwaZulu-Natal, South Africa and to describe pharmacy refill records as reliable monitoring method of antiretroviral therapy. In total, 61 patients' records were reviewed. Overall, 50 (82%) of the patients achieved an optimum adherence level of at least 90%, whereas 19 (38%) of these patients did not show any related viral suppression. A statistically significant relationship between adherence and viral suppression was not demonstrated. Therefore, pharmacy refill records cannot be recommended as an alternative method of monitoring response to antiretroviral therapy, but laboratory tests including CD4 cell count and or viral load must be combined with the pharmacy refill method for monitoring of antiretroviral therapy in HIV-positive patients.

We evaluated the risk factors associated with oral human papillomavirus (HPV) infection and oral lesions in 161 human immunodeficiency virus (HIV)–positive patients and 128 HIV-negative patients presenting for oral examination at 2 urban healthcare centers. Patients were interviewed on risk factors and provided oral-rinse samples for HPV DNA typing by polymerase chain reaction. Statistical associations were assessed by logistic regression. Oral HPV was prevalent in 32% and 16% of HIV-positive patients and HIV-negative patients, respectively, including high-risk HPV type 16 (8% and 2%, respectively; P = .049) and uncommon HPV types 32/42 (6% and 5%, respectively; P = .715). Among HIV-negative patients, significant risk factors for oral HPV included multiple sex partners (≥21 vs ≤5; odds ratio [OR], 9.1; 95% confidence interval [CI], 1.7–49.3), heavy tobacco smoking (>20 pack-years vs none; OR, 9.2; 95% CI, 1.4–59.4), and marijuana use (OR, 4.0; 95% CI, 1.3–12.4). Among HIV-positive patients, lower CD4+ T-cell count only was associated with oral HPV detection (≤200 vs ≥500 cells/mm3; OR, 4.5; 95% CI, 1.3–15.5). Detection of high-risk HPV was also associated with concurrent detection of potentially cancerous oral lesions among HIV-negative patients but not among HIV-positive patients. The observed risk factor associations with oral HPV in HIV-negative patients are consistent with sexual transmission and local immunity, whereas in HIV-positive patients, oral HPV detection is strongly associated with low CD4+ T-cell counts.

Anal cancer is an increasing problem among HIV-infected persons. Although patients are living longer and with better quality of life because of treatment with HAART, they remain at risk for invasive anal cancer and its precursor, anal HSIL. Given the substantial numbers of patients with anal HSIL, further studies need to be done to determine the efficacy and optimal mode of treatment of HSIL, to define the optimal method for screening patients at risk, to define the best way to follow up patients with documented HSIL to ensure early detection, to define prognostic factors for progression to invasive cancer, and to determine the progression rate of HSIL to invasive cancer. Although patients with good functional status and immunologic function seem to do relatively well with standard CMT for anal cancer, there are less fortunate patients who experience substantial morbidity from therapy and have a poorer outcome. It is difficult to draw definitive conclusions about the therapy of HIV-positive patients with anal cancer based on the available literature because of the retrospective nature of the analyses, the small number of patients, and the heterogeneity of the patients reported with regard to tumor size, pretreatment immunologic status, and the variety of treatments received by patients in some series. Identifying patients who develop invasive anal cancer as early as possible will improve results to some degree, but prospective, controlled, multi-institutional trials evaluating the treatment of anal cancer in HIV-infected persons are required to accurately define ways to improve outcome with less morbidity. The results of ongoing therapeutic HPV vaccine trials are eagerly awaited. Improvement may come by the following, determining ways to more accurately stage patients, such as endoanal ultrasound, sentinel lymph node sampling, or positron emission tomography scans; defining the role of cisplatin and whether it is indeed less toxic and equally or more effective

In spite of the availability and accessibility of HIV testing opportunities and efforts, people are being late to test in the course of HIV infection. Late diagnosis leads to late anti-retroviral therapy initiation which in turn results in poor treatment outcome and prognosis of the disease. The aim of this study was to determine the prevalence and predictors of late HIV diagnosis among HIV-infected patients in South Tigray Zone, Ethiopia. A facility based cross sectional study was conducted among HIV positive patients from February 1-30, 2014 in Southern Tigray, Ethiopia. Multistage sampling technique was employed to select the study participants. Data were collected by reviewing patient medical card and interviewing using structured questionnaire. Data were entered using Epi-Data version 3.1 and analyzed using SPSS version 20.0. Both bivariate and multivariate logistic regressions were modeled to evaluate the association of predictors with late diagnosis of HIV infection. Out of 789 study participants, 68.8 % of them were late for HIV diagnosis. Feeling healthy (65.7 %), fear of stigma and discrimination (32.4 %) and using traditional treatment (1.5 %) were reported as the main reasons for late HIV diagnosis. Use of Khat [AOR = 3.27, 95 % CI (1.75, 6.13)], bed ridden functional status [AOR = 2.66, 95 % CI (1.60, 4.42)], ambulatory functional status [AOR = 1.56, 95 % CI (1.03, 2.35)] and Muslim religion [AOR = 2.26, 95 % CI (1.13, 4.49)] were significantly associated with late presentation for HIV diagnosis. High prevalence of late HIV diagnosis was recorded in Southern Tigray Zone, Ethiopia. Public health educations and campaigns targeted at improving early diagnosis and prognosis of people living with HIV/AIDS in Southern Tigray, Northern Ethiopia should be underway.

Chronic viral hepatitis has emerged as one of the leading causes of morbidity and mortality among HIV-positive patients. These individuals are at risk for aggressive chronic active hepatitis, cirrhosis, and hepatocellular carcinoma, and eventually, death. Currently available therapies for hepatitis B are limited and include interferon-alpha, lamivudine (3TC), and adefovir. Tenofovir (TDF), a recently approved drug for the treatment of HIV, is also active against hepatitis B. We report the case of a HIV-positive patient with liver cirrhosis secondary to chronic hepatitis B virus (HBV) with evidence of resistance to 3TC. The patient was initially accepted as a liver transplant candidate. However, when TDF was added to his treatment, a remarkable virologic and histopathologic improvement was achieved. The patient was subsequently removed from the liver transplant program and has not suffered from any further hepatic complications.

Occult hepatitis B infection (OBI) among HIV positive patients varies widely in different geographic regions. We undertook a study to determine the prevalence of occult hepatitis B infection among HIV infected individuals visiting a health facility in South West Cameroon and characterized occult HBV strains based on sequence analyses. Plasma samples (n = 337), which previously tested negative for hepatitis B surface antigen (HBsAg), were screened for antibodies against hepatitis B core (anti-HBc) and surface (anti-HBs) antigens followed by DNA extraction. A 366 bp region covering the overlapping surface/polymerase gene of HBV was then amplified in a nested PCR and the amplicons sequenced using Sanger sequencing. The resulting sequences were then analyzed for genotypes and for escape and drug resistance mutations. Twenty samples were HBV DNA positive and were classified as OBI giving a prevalence of 5.9%. Out of these, 9 (45%) were anti-HBs positive, while 10 (52.6%) were anti-HBc positive. Additionally, 2 had dual anti-HBs and anti-HBc reactivity, while 6 had no detectable HBV antibodies. Out of the ten samples that were successfully sequenced, nine were classified as genotype E and one as genotype A. Three sequences possessed mutations associated with lamivudine resistance. We detected a number of mutations within the major hydrophilic region of the surface gene where most immune escape mutations occur. Findings from this study show the presence of hepatitis B in patients without any of the HBV serological markers. Further prospective studies are required to determine the risk factors and markers of OBI.

Occult HBV infection (OBI), defined by the presence of HBV DNA in absence of hepatitis B surface antigen (HBsAg), is a significant concern in the HIV-infected population. Of 441 HIV+/HBsAg- patients analyzed, the overall prevalence of OBI was 6.3% (28/441). OBI was identified in 21 anti-HBc positives (17.8%), as well as among those who lacked any HBV-specific serological markers (2.2%). Comparison with HIV/HBV co-infection revealed that the levels of CD4, ALT, and HBV DNA were significantly lower during occult infection. Discrete differences were also observed with respect to quasispecies divergence. Additionally, subgenotype D1 was most frequent in occult infection, while D2 was widespread during chronic infection. The majority (~90%) of occult D1 sequences had the sQ129R mutation in the surface gene. This study highlights several distinct features of OBI in India and underscores the need for additional HBV DNA screening in HIV-positive individuals.

The human immunodeficiency virus (HIV) epidemic facilitated the resurgence of extrapulmonary tuberculosis (TB) and other opportunistic diseases. This study assessed the sociodemographic and cytopathologic patterns of enlarged cervical lymph nodes among HIV positive and negative patients. This prospective cross sectional study was conducted in Agaro Health centre, Agaro town, Oromia regional state, south western Ethiopia, for a period between April 2008 and September 2008. The instruments of the study were a structured questionnaire for data collection, fine needle aspirate cytology (FNAC) technique for the lymph nodes aspirates and blood drawn for HIV testing. The aspirates were also cultured by using Löwenstein-Jensen medium (LJ) medium. Finally, all data was cleaned, entered and analyzed by using SPSS version 13.00 statistical software and P-Value was taken significant when less than 0.05. A total of 82 patients were enrolled into this study. Nineteen (23.2%) patients were HIV positive. Tuberculous adenitis was the most frequent diagnosis 47/82 (57.3%). HIV positivity in patients with enlarged cervical adenopathy was 19/82 (23.2%) however, HIV and TB adenitis co-infection was 12/47 (25.5%) in the studied patients (P-Value = 0.57). TB was diagnosed cytologically in 5/11 ulcerated nodes, 11/28 purulent aspirates and 7/15 aspirates showing caseous necrosis without cellular reactions. About one-fourth (25.5%) of tuberculous lymph adenitis patients were co-infected with HIV. Pussy aspirates macroscopically and caseous necroses without cellularity microscopically were more common among HIV positive patients in this study. Thus, caseous necrosis with acellular reactions with or without pussy aspirates and nodal ulceration could hint immunodeficient status in co-infected individuals but this speculation need to be verified in a larger scale prospective study.

Lipid disorders associated with the use of protease inhibitors (PI) may be a risk factor for premature atherosclerosis development. The aim of this study is to evaluate the extent of carotid intima media thickness (IMT) among HIV-positive patients treated with PI containing regimens compared to PI-naïve and HIV-negative subjects. We analysed plasma lipid levels and carotid IMT in 28 HIV-positive patients treated with protease inhibitors (PIs) for a mean of 28.7 months (range 18-43) and in two control groups constituted, respectively, by 15 HIV-positive naïve patients and 16 HIV-negative subjects, that were matched for age, risk factors for HIV infection, cigarette smoke use and CD4+ cell count. PI-treated patients had higher triglyceride, HDL and apo B levels than controls. Carotid IMT was significantly increased in PI-treated patients compared to naïve or HIV-negative subjects. A correlation between cholesterol HDL, triglyceride and ApoB levels and IMT was observed among the entire cohort. Plasma lipid alterations were associated with an increased IMT and intima media thickening was more pronounced in PI-treated patients than in the two control groups. Periodical evaluation of blood lipid profile and, if required, the use of lipid-lowering agents is advisable. Moreover, physicians should address concurrent risk factor for atherosclerosis that can be modified, including smoking, hypertension, obesity and sedentary life-style.

Cryptococcus neoformans strains isolated from 207 HIV positive and HIV negative patients hospitalized in Northern Italy were serotyped by slide agglutination. One Brazilian HIV negative woman was infected by var. gattii serotype B and all the other patients by var. neoformans, serotype D in 71%, serotype A in 24.6% and serotype AD in 3.4%. No difference was observed between subjects with serotypes A and D in HIV coinfection, exposure categories for AIDS, age, sex, and CD4 count of HIV positive patients. Meningeal and respiratory tract involvements and prostatic reservoir occurred with comparable frequency in AIDS patients infected by serotypes A and D. Skin lesions were observed only in serotype D infections, occurring in 12.6% of HIV positive and 58.3% of HIV negative patients infected by this serotype. Serotype A was found less susceptible to fluconazole than serotype D: 53.7% of serotype A strains had a MIC > or = 25 micrograms ml-1 compared to 17.7% of the serotype D isolates. On the other hand, both serotypes were highly susceptible to itraconazole.

A survey on intestinal parasites in a rural area of Tanzania revealed the presence of eight protozoa and seven helminths in 287 subjects (81.8%). The prevalence of Entamoeba histolytica and Ascaris lumbricoides was higher in HIV-negative than in HIV-positive patients (P < 0.01; P < 0.04) (25.1% and 12.5% for E. histolytica; 10.5% and 3.7% for A. lumbricoides). On the other hand, Cryptosporidium parvum, Isospora belli and Strongyloides stercoralis prevalence was higher in HIV-positive than in HIV-negative patients (P < 0.01). The prevalence of these two opportunistic protozoa was also higher in AIDS patients than in HIV-positive patients without AIDS. Specific anti-C. parvum IgG were detected by ELISA in 18% and 56% of HIV-negative and positive patients, respectively, confirming the high number of contacts between this parasite and humans. Specific anti-Encephalitozoon cuniculi and anti-Encephalitozoon hellem IgG were detected by IFA in 18% and 19% of subjects, respectively, without any correlation with HIV and malaria infections.

To present two cases of probable lymphoepithelial cysts of the submandibular glands in patients who were human immunodeficiency virus (HIV) positive and who also had lymphoepithelial cysts of the parotid glands. Computed tomography and MRI of two HIV positive patients with lymphoepithelial cysts of the parotid glands and cysts in tile submandibular glands were correlated with the histories and the possible presence of other known causes of submandibular gland multiple cysts. Because of the present treatment philosophy regarding HIV positive patients with major salivary gland cysts, surgical resection of these glands was not performed. All other known causes of multiple submandibular gland cysts were excluded by either history or laboratory data. Computed tomography and MRI on two patients with known HIV infection and bilateral parotid lymphoepithelial cysts are presented. Both patients also had bilateral multiple submandibular gland cysts and no evidence of obstructive glandular diseases autoimmune disease, or other organ system cysts. These cases of presumed submandibular gland lymphoepithelial cysts are rare in the literature. They are presented in the hope that other radiologists will be stimulated to document the occurrence of this entity. 22 refs., 2 figs.

The lipodystrophy syndrome (LDS) is a growing problem in human immunodeficiency virus (HIV)-positive patients treated with highly active antiretroviral therapy (HAART). It is characterized by alterations of body composition and metabolic abnormalities. The goal of the study was to investigate attitudes toward health condition, well-being, and individual appearance in relation to LDS. Outpatients between July and October 2000 in an HIV-specialized unit at the University Hospital of Düsseldorf, Germany, underwent clinical evaluation and received a standardized written questionnaire. Of 389 patients eligible for analysis, 313 patients returned completed questionnaires (response rate, 80.5%). LDS was observed in 37.7%; the predominant manifestation was lipoatrophy of the face (32.9%). Individuals with and without LDS did not differ significantly in their attitude to the quality of their health condition and the amount of disturbance of their well-being by HIV infection. Participants with LDS felt recognizable as HIV-positive by physical appearance in 30.1%, compared to 18.3% in patients without LDS (p = 0.027). This difference became more pronounced after adjustment for gender, age, stage of disease, CD4 cell count, and duration of HAART (odds ratio, 2.04, 95%-confidence interval [CI] 1.09-3.84). In conclusion, LDS does not seem to disturb the general attitude toward health condition and well-being. However, patients presenting with lipodystrophy are about twice as likely to feel recognizable as HIV-positive by their physical appearance. LDS may thus be perceived as a characteristic mark of being HIV-positive by affected persons. A stigmatizing effect and social disadvantages may be the consequences.

The retention of patients on antiretroviral therapy (ART) is key to achieving global targets in response to the HIV epidemic. Loss to follow-up (LTFU) can be substantial, with unknown outcomes for patients lost to ART programmes. We examined changes in outcomes of patients LTFU over calendar time, assessed associations with other study and programme characteristics and investigated the relative success of different tracing methods. We performed a systematic review and logistic random-effects meta-regression analysis of studies that traced adults or children who started ART and were LTFU in sub-Saharan African treatment programmes. The primary outcome was mortality, and secondary outcomes were undocumented transfer to another programme, treatment interruption and the success of tracing attempts. We included 32 eligible studies from 12 countries in sub-Saharan Africa: 20 365 patients LTFU were traced, and 15 708 patients (77.1%) were found. Compared to telephone calls, tracing that included home visits increased the probability of success: the adjusted odds ratio (aOR) was 9.35 (95% confidence interval [CI] 1.85-47.31). The risk of death declined over calendar time (aOR per 1-year increase 0.86, 95% CI 0.78-0.95), whereas undocumented transfers (aOR 1.13, 95% CI 0.96-1.34) and treatment interruptions (aOR 1.31, 95% CI 1.18-1.45) tended to increase. Mortality was lower in urban than in rural areas (aOR 0.59, 95% CI 0.36-0.98), but there was no difference in mortality between adults and children. The CD4 cell count at the start of ART increased over time. Mortality among HIV-positive patients who started ART in sub-Saharan Africa, were lost to programmes and were successfully traced has declined substantially during the scale-up of ART, probably driven by less severe immunodeficiency at the start of therapy. © 2017 John Wiley & Sons Ltd.

The number of HIV-positive people aged ≥50 years is rising each year. We measured the prevalence of non-infectious illnesses and their risk factors and described healthcare use in this UK population. A cross-sectional, observational study was conducted at an outpatient HIV specialist clinic in south east England. Patients age ≥50 years were invited to complete questionnaires measuring demographics, non-infectious illnesses, medication use, lifestyle and healthcare utilisation. The response rate was 67%. Of 299 participants, 84% reported ≥1 comorbid condition and 61% reported ≥2 (multimorbidity). Most commonly reported were high cholesterol, sexual dysfunction, hypertension and depression. In multivariate analyses, age, number of years HIV-positive and duration of antiretroviral therapy remained significant predictors of comorbidity when controlling for lifestyle factors (exercise, smoking and use of recreational drugs and alcohol). Use of non-HIV healthcare services was associated with increasing comorbidity, a longer duration of HIV and recreational drug use. The majority of HIV-patients aged ≥50 years reported multiple comorbidities and this was associated with polypharmacy and increased use of non-HIV services. Further research examining the quality, safety and patient experience of healthcare is needed to inform development of services to optimally meet the needs of older HIV-positive patients.

Background and objectives Prior studies have shown that the APOL1 risk alleles are associated with a greater risk of HIV-associated nephropathy and FSGS among blacks who are HIV positive. We sought to determine whether the APOL1 high–risk genotype incrementally improved the prediction of these underlying lesions beyond conventional clinical factors. Design, setting, participants, & measurements In a cross-sectional study, we analyzed data from 203 blacks who are HIV positive, underwent kidney biopsies between 1996 and 2011, and were genotyped for the APOL1 G1 and G2 alleles. Predictive logistic regression models with conventional clinical factors were compared with those that also included APOL1 genotype using receiver-operating curves and bootstrapping analyses with crossvalidation. Results The addition of APOL1 genotype to HIV–related risk factors for kidney disease in a predictive model improved the prediction of non–HIV–associated nephropathy FSGS, specifically, increasing the c statistic from 0.65 to 0.74 (P=0.04). Although two risk alleles were significantly associated with higher odds of HIV-associated nephropathy, APOL1 genotype did not add incrementally to the prediction of this specific histopathology. Conclusions APOL1 genotype may provide additional diagnostic information to traditional clinical variables in predicting underlying FSGS spectrum lesions in blacks who are HIV positive. In contrast, although APOL1 risk genotype predicts HIV-associated nephropathy, it lacked a high c statistic sufficient for discrimination to eliminate the role of kidney biopsy in the clinical care of blacks who are HIV positive with nephrotic proteinuria or unexplained kidney disease.

The existing information on oral rehabilitations with dental implants in VIH-positive patients is scarce and of poor quality. Moreover, no long-term follow-up studies are available. Hence, the aims of this study were to describe the long-term survival and success rates of dental implants in a group of HIV-positive patients and to identify the most common postoperative complications, including peri-implant diseases. A retrospective case series of HIV-positive subjects treated with dental implants at the School of Dentistry of the University of Barcelona (Spain) was studied. Several clinical parameters were registered, including CD4 cell count, viral load and surgical complications. Additionally, the patients were assessed for implant survival and success rates and for the prevalence of peri-implant diseases. A descriptive statistical analysis of the data was performed. Nine participants (57 implants) were included. The patients' median age was 42 years (IQR=13.5 years). The implant survival and success rates were 98.3% and 68.4%, respectively, with a mean follow-up of 77.5 months (SD=16.1 months). The patient-based prevalence of peri-implant mucositis and peri-implantitis were 22.2% and 44.4% respectively at the last appointment. Patients that attended regular periodontal maintenance visits had significantly less mean bone loss than non-compliant patients (1.3 mm and 3.9 mm respectively). Oral rehabilitation with dental implants in HIV-positive patients seems to provide satisfactory results. In order to reduce the considerably high prevalence of peri-implant diseases, strict maintenance programmes must be implemented.

Blood brain barrier impairment occurs early in the course of infection by HIV and it may persist in a subset of patients despite effective antiretroviral treatment. We tested the hypothesis that HIV-positive patients with dysfunctional blood brain barrier may have altered biomarkers of neuronal damage. In adult HIV-positive highly active antiretroviral treatment (HAART)-treated patients (without central nervous system infections and undergoing lumbar punctures for clinical reasons) cerebrospinal fluid albumin to serum ratios (CSAR), total tau, phosphorylated tau, 1-42 beta amyloid, and neopterin were measured. In 101 adult patients, cerebrospinal fluid-to-serum albumin ratios were 4.8 (3.7-6.1) with 12 patients (11.9%) presenting age-defined impaired blood brain barrier. A significant correlation was observed between CSAR and total tau (p = 0.005), phosphorylated tau (p = 0.008), and 1-42 beta amyloid (p = 0.040). Patients with impaired blood brain barrier showed significantly higher total tau (201.6 vs. 87.3 pg/mL, p = 0.010), phosphorylated tau (35.3 vs. 32.1 ng/mL, p = 0.035), and 1-42 beta amyloid (1134 vs. 830 pg/mL, p = 0.045). Despite effective antiretroviral treatment, blood brain barrier impairment persists in some HIV-positive patients: it is associated with markers of neuronal damage and it was not associated with CSF neopterin concentrations.

AIMS: To compare the density of neuroendocrine cells in rectal biopsy specimens from human immunodeficiency virus (HIV) infected individuals with that of a control group. METHODS: Neuroendocrine cells in rectal biopsies were identified using an immunohistochemical stain for chromogranin and subsequently quantified using a method of linear intercept. RESULTS: Neuroendocrine cells were found to be significantly decreased in the HIV positive group. CONCLUSIONS: Loss of neuroendocrine cells may contribute to apoptotic bodies seen in this condition. This could be related to infection of these cells with HIV and could contribute to diarrhoeal disease in HIV infection. Images PMID:1624601

As the relative burden of community-acquired bacterial pneumonia among HIV-positive patients increases, adequate prediction of case severity on presentation is crucial. We sought to determine what characteristics measurable on presentation are predictive of worse outcomes. We studied all admissions for community-acquired bacterial pneumonia over one year at a tertiary centre. Patient demographics, comorbidities, HIV-specific markers and CURB-65 scores on Emergency Department presentation were reviewed. Outcomes of interest included mortality, bacteraemia, intensive care unit admission and orotracheal intubation. A total of 396 patients were included: 49 HIV-positive and 347 HIV-negative. Mean CURB-65 score was 1.3 for HIV-positive and 2.2 for HIV-negative patients (p < 0.0001), its predictive value for mortality being maintained in both groups (p = 0.03 and p < 0.001, respectively). Adjusting for CURB-65 scores, HIV infection by itself was only associated with bacteraemia (adjusted odds ratio [AOR] 7.1, 95% CI [2.6-19.5]). Patients with < 200 CD4 cells/µL presented similar CURB-65 adjusted mortality (aOR 1.7, 95% CI [0.2-15.2]), but higher risk of intensive care unit admission (aOR 5.7, 95% CI [1.5-22.0]) and orotracheal intubation (aOR 9.1, 95% CI [2.2-37.1]), compared to HIV-negative patients. These two associations were not observed in the > 200 CD4 cells/µL subgroup (aOR 2.2, 95% CI [0.7-7.6] and aOR 0.8, 95% CI [0.1-6.5], respectively). Antiretroviral therapy and viral load suppression were not associated with different outcomes (p > 0.05). High CURB-65 scores and CD4 counts < 200 cells/µL were both associated with worse outcomes. Severity assessment scales and CD4 counts may both be helpful in predicting severity in HIV-positive patients presenting with community-acquired bacterial pneumonia. © The Author(s) 2016.

Multidrug-resistant tuberculosis (MDR-TB) and the human immunodeficiency virus (HIV) pose two of the greatest threats to global tuberculosis (TB) control. Given expanding global access to antiretroviral therapy (ART) and second-line TB drugs, more data are needed on experiences treating MDR-TB and HIV co-infection in resource-poor settings. To describe the clinical characteristics, management, outcomes, and factors associated with survival among HIV-positive individuals receiving treatment for MDR-TB. This was a retrospective case series of 52 HIV-positive individuals receiving treatment for MDR-TB in Lima, Peru. We used Cox proportional hazards regression models to identify risk factors for mortality. A total of 31 (57%) of the cohort died on treatment, with the majority of deaths due to MDR-TB. Low baseline weight predicted a three-fold increased rate of death (aHR 3.1, 95%CI 1.5-6.7), while individuals receiving highly active ART experienced a significantly lower rate of death compared to those who were not (aHR 0.4, 95%CI 0.2-0.9). Early ART is likely a key component of effective MDR-TB management in co-infected individuals.

Microsporidia are intracellular obligate parasites, today mainly associated with diarrhea in AIDS patients. Microsporidia prevalence ranges from 8% to 52% in different countries, as evaluated by several diagnostic methods, such as the stain test and PCR. In Medellín, Colombia, its frequency is unknown, and hence, a study was undertaken to determine the frequency of intestinal microsporidiosis in HIV patients, by means of the quick-hot Gram chromotrope test and the PCR. A prospective and descriptive study of an intentional population of all HIV-positive patients was sent to the Grupo Interdisciplinario para el Estudio de las Parasitosis Intestinales laboratory by institutions treating the HIV-positive patients of Medellín between August 2001 and September 2002. The clinical-epidemiological survey included a serial stool test with direct concentration and special stains for coccidiae and intestinal microsporidia. In addition, counts of lymphocytes TCD4+ and viral load were requested. One hundred and three patients with ages ranging from 2-74 years were evaluated. Seventy percent presented with diarrhea--mostly in men (83.5%). The overall frequency of intestinal microsporidiosis was 3.9% and that of other intestinal parasitic infections was 39.8%. Three of the four patients positive for microsporida were infected with Enterocytozoon bieneusi and one with Encephalitozoon intestinalis. The microsporidiosis frequency was relatively low with 3 of the 4 cases associated with protracted diarrhea, counts of LTCD4+ below 100 cel/microl and viral loads up to 100,000 copies.

To longitudinally evaluate the cortical thickness and deep gray matter structures volume, measured from T1 three-dimensional (3D) Gradient echo-weighted imaging, and white matter integrity, assessed from diffusion tensor imaging (DTI) of HIV-positive patients. Twenty-one HIV-positive patients on stable highly active antiretroviral therapy (HAART) with CD4+ T lymphocytes count >200 cells/mL and viral load <50 copies/mL underwent two magnetic resonance imaging (MRI) scans with a median interval of 26.6 months. None of the patients had HIV-related dementia. T1 3D magnetization prepared rapid gradient echo-weighted imaging and DTI along 30 noncolinear directions were performed using a 1.5 Tesla MR scanner. FreeSurfer was used to perform cortical volumetric reconstruction and segmentation of deep gray matter structures. For tract-based spatial statistics analysis, a white matter skeleton was created, and a permutation-based inference with 5000 permutations, with a threshold of P < 0.05 was used to identify abnormalities in fractional anisotropy (FA). The median, radial, and axial diffusivities were also projected onto the mean FA skeleton. There were no significant differences in cortical thickness, deep gray matter structures volumes or diffusivity parameters between scans at the two time points (considering P < 0.05). No longitudinal differences in cortical thickness, deep gray matter volumes, or white matter integrity were observed in an HIV-positive population on stable HAART, with undetectable viral load and high CD4+ T lymphocytes count.

Abstract Background This study examined the practices, knowledge, attitudes, and the reasons for disclosure and non-disclosure of HIV-positive patients with regard to the disclosure of HIV results at Betesda Clinic in Windhoek, Namibia. Objectives The objectives of the study were to determine knowledge, attitudes, and practices of HIV-positive patients regarding the disclosure of HIV status at Betesda Clinic in Namibia, and to determine the reasons for disclosure and non-disclosure. Methods This was a cross-sectional descriptive study and 263 HIV-positive patients were enrolled in the study. Results Analyses revealed that knowledge on disclosure was good, with 68% who thought it was important. The majority (73%) have disclosed and 60% disclosed within 1 week of receiving their results. The most common reasons for disclosure were that 32% needed help, 25% wanted his or her partner to go for testing, and 20% wanted to let relatives know. Reasons for non-disclosure were mainly the fear of gossip (79%). Seventy-three per cent had disclosed to their partners, and 23% had disclosed to more than one person. People's reactions were supportive in 43%, whereas 29% understood, 9% accepted and 6% were angry. Upon disclosure 40% received help, 24% of partners were tested, 23% received psychological support and 5% were stigmatised. Disclosure was higher amongst the married and cohabitating. Conclusion The attitude was positive with regard to knowledge of disclosure, with most participants thinking that disclosure was important and good. The attitudes and actual practices of disclosure were encouraging; however, people are disclosing only to trusted individuals in the society and the fear of stigma is still present although the actual stigma was very low.

Supplementation of conventional medicines with herbs is increasing globally, including among people infected with HIV. Yet there is little data systematically describing the prevalence and patterns of this supplementation and on which counseling scripts can be based. Moringa oleifera is an herb found in the tropics and sub-tropics commonly used for medicinal and nutritional purposes. This survey determined the prevalence and patterns of use of M. oleifera among HIV positive patients. The study was a cross-sectional survey. HIV-infected adults were enrolled from an opportunistic infections clinic of a referral hospital. Using a previously piloted researcher administered questionnaire; patients who reported to the clinic over three months were interviewed about their use of herbal medicines. The focus was on M. oleifera use, and included plant part, dosage, prescribers and the associated medical conditions. Sixty-eight percent (68%) of the study participants consumed M. oleifera. Of these, 81% had commenced antiretroviral drugs. Friends or relatives were the most common source of a recommendation for use of the herb (69%). Most (80%) consumed M. oleifera to boost the immune system. The leaf powder was mainly used, either alone or in combination with the root and/or bark. M. oleifera supplementation is common among HIV positive people. Because it is frequently prescribed by non-professionals and taken concomitantly with conventional medicine, it poses a potential risk for herb-drug interactions. Further experimental investigations into its effect on drug metabolism and transport would be useful in improving clinical outcome of HIV positive patients.

Accessory breast is a rare entity that can present as asymptomatic masses or can cause symptoms like heaviness, pain, restriction of arm movement and limitation in daily pursuits with allied apprehension and anxiety for the patient. We present a case of bilateral axillary masses mimicking as accessory breast with multiple fibroadenoma in a 28 years, nulliparous, Indian woman who is HIV positive, which proves to be a diagnostic dilemma. Excisional biopsy was diagnostic. The rarity of such cases imposes challenges on the management in terms of diagnosis, prognosis and therapeutic options.

Introduction: Cryptococcal meningitis (CM) may be caused by several species of Cryptococcus. Case presentation: We describe a fatal case of CM in a HIV-positive patient from Ivory Coast infected by Cryptococcus neoformans VNI and Cryptococcus deuterogattii. Isolates were recovered from cerebrospinal fluid (CSF) prior to systemic antifungal treatment. Six isolates were studied (the entire culture plus five isolated colonies from it). Serotyping was performed via LAC 1 and CAP 64 gene amplification. Genotyping was performed using restriction fragment length polymorphism (RFLP) analysis of the URA5 gene, (GACA)4, (GTG)5 and M13 PCR fingerprinting. URA5-RFLP analysis identified the original culture with two different molecular type combinations. However, URA5-RFLP profiles of the five colonies isolated from the original sample revealed two different species. Four colonies were identified as C. deuterogattii and the last isolate as C. neoformans VNI. The in vitro susceptibility profile was determined using the standard method according to the CLSI M27-A3 protocol. The isolates were susceptible to the tested antifungals (fluconazole, flucytosine and amphotericin B). Treatment with fluconazole (1200 mg day−1) was initiated; however, the patient died 17 days after the onset of antifungal therapy. Conclusion: This is the first reported case of mixed infection with C. neoformans and C. deuterogattii in a HIV-positive patient. PMID:28348767

This retrospective study assessed whether Quality Improvement Scotland national standards for the sexual health care offered to HIV-positive individuals are being met by the Edinburgh genitourinary (GU) medicine clinic; specifically whether HIV-positive patients are offered: (a) sexually transmitted infection (STI) screening annually and (b) syphilis testing six-monthly. The study also reviewed what factors were associated with a clinician's offer of STI screening and syphilis testing. Of the 509 patients seen within the study period, case notes documented that 64% were offered STI screens, and 69% were offered syphilis testing, results consistent with audits of services elsewhere. Sexual orientation (P < 0.0005), relationship status (P = 0.007) and receipt of antiretrovirals (P = 0.001) were independent predictors of clinician offer of STI screening, while gender (P < 0.0005) and receipt of antiretrovirals (P = 0.063) were independent predictors of offer of syphilis testing. Our results suggest that one explanation for clinicians failing to offer STI screens and syphilis serology testing is their (implicit) risk assessment that STI testing is not required in individual patients.

The purpose of this study was to investigate how HIV-positive patients and infectious disease healthcare providers think about death, dying, and end-of-life care planning. We conducted separate in-depth qualitative interviews with 47 patients and 11 providers. Interview data were transcribed and analyzed using a secondary comparative method. Patients and providers demonstrated profound differences in their perspectives on patient empowerment and attributions of control related to disease progression, imminence of death, and end-of-life care decision-making. Notably, patients described fears related to life-extending interventions that generally went unaddressed within the clinical context. We argue for the routinization of end-of-life care discussions and suggest novel research approaches to improve patient empowerment and medical engagement. PMID:24316681

A prospective study of 55 confirmed or presumptive cases of cerebral toxoplasmosis in HIV positive patients in Brazil was performed to describe clinical characteristics and to identify predictive factors for clinical response to the anti-Toxoplasma treatment. Cerebral toxoplasmosis led to the diagnosis of HIV infection in 19 (35%) patients, whereas it was the AIDS defining disease in 41 (75%) patients. Of these, 22 (54%) patients were previously know to be HIV-positive. At diagnosis of cerebral toxoplasmosis, only 4 (7%) patients were on highly active antiretroviral therapy (HAART), and 6 (11%) were receiving primary cerebral toxoplasmosis prophylaxis. The mean CD4+ cell count was 64.2 (+/- 69.1) cells per microliter. Forty-nine patients (78%) showed alterations consistent with toxoplasmosis on brain computed tomography. At 6 weeks of treatment, 23 (42%) patients had complete clinical response, 25 (46%) partial response, and 7 (13%) died. Alteration of consciousness, Karnofsky score less than 70, psychomotor slowing, hemoglobin less than 12 mg/dL, mental confusion, Glasgow Coma Scale less than 12 were the main predictors of partial clinical response. All patients were placed on HAART within the first 4 weeks of diagnosis of cerebral toxoplasmosis. One year after the diagnosis, all available patients were on HAART and toxoplasmosis prophylaxis, and only 2 patients had relapse of cerebral toxoplasmosis. In Brazilian patients with AIDS, cerebral toxoplasmosis mainly occurs as an AIDS-defining disease, and causes significant morbidity and mortality. Signs of neurologic deterioration predict an unfavorable response to the treatment. Early start of HAART seems to be related to better survival and less relapses.

Background Inconsistent literature evidence suggests that sociodemographic, economic, and system- and patient-related factors are associated with clinic attendance among the HIV-positive population receiving antiretroviral therapy (ART) around the world. We examined the factors that predict outpatient clinic attendance among a cohort of HIV-positive patients initiating ART in Selangor, Malaysia. Patients and methods This cross-sectional study analyzed secondary data on outpatient clinic attendance and sociodemographic, economic, psychosocial, and patient-related factors among 242 adult Malaysian patients initiating ART in Selangor, Malaysia. Study cohort was enrolled in a parent randomized controlled trial (RCT) in Hospital Sungai Buloh Malaysia between January and December 2014, during which peer counseling, medication, and clinic appointment reminders were provided to the intervention group through short message service (SMS) and telephone calls for 24 consecutive weeks. Data on outpatient clinic attendance were extracted from the hospital electronic medical records system, while other patient-level data were extracted from pre-validated Adult AIDS Clinical Trial Group (AACTG) adherence questionnaires in which primary data were collected. Outpatient clinic attendance was categorized into binary outcome – regular attendee and defaulter categories – based on the number of missed scheduled outpatient clinic appointments within a 6-month period. Multivariate regression models were fitted to examine predictors of outpatient clinic attendance using SPSS version 22 and R software. Results A total of 224 (93%) patients who completed 6-month assessment were included in the model. Out of those, 42 (18.7%) defaulted scheduled clinic attendance at least once. Missed appointments were significantly more prevalent among females (n=10, 37.0%), rural residents (n=10, 38.5%), and bisexual respondents (n=8, 47.1%). Multivariate binary logistic regression analysis showed that

Despite strong evidence that antiretroviral therapy (ART) reduces the risk of mother-to-child transmission of HIV and improves the health of HIV-positive mothers, many HIV-positive pregnant women do not enrol into long-term HIV care and treatment. This study examined barriers and facilitators to the linkage of HIV-positive pregnant women from antenatal care (ANC) to long-term HIV care from patient and provider perspectives, following the implementation of a collaborative quality improvement project in Eastern Uganda. It also solicited recommendations for improving linkages to HIV care. Structured interviews were conducted with 11 health providers and 48 HIV-positive mothers enrolled in HIV care. Facilitators to linking HIV-positive pregnant women to long-term HIV care identified included support from expert clients, escorted referrals, same-day HIV care registration, and coordination between ANC and HIV services. Barriers reported included shortages in HIV testing kits and fear of social, physical and medical consequences. Participants recommended integration of ANC and HIV services, reduction in waiting times, HIV counselling by expert clients, and community-based approaches for improving linkages to HIV care. Linking HIV-positive pregnant women to HIV care can be improved through deliberate implementation of quality improvement interventions in facilities to address barriers to access and provide stronger support and community mobilisation.

Data on risky sexual behaviors in people living with HIV/AIDS (PLWHA) is still scarce in some populations around the world. The purpose of this study was to assess the factors associated with the use of condoms in a representative sample of PLWHA in outpatient treatment in the city of São Paulo. Six hundred and sixty-seven HIV-positive patients (383 men and 284 women) who were being treated at eight centers participated in this study. Data were collected using a sociodemographic survey, the Beck depression and anxiety inventories, a survey of alcohol and other drugs use, the Alcohol Use Disorders Identification Test, a sexual behavior survey, and the Sexual Risk Behavior Assessment Schedule. The majority of study participants were sexually active (almost 62% of the sample had at least one sexual partner in the last three months), and at least one-fourth engaged in unsafe sex (25.3% did not use condoms during at least one instance of anal and/or vaginal intercourse in the past three months). Multivariate logistic regression showed that engaging in unprotected sex was more likely among females (p < .001), persons with an HIV-positive partner (p < .001), and people using cannabis before sex (p = .002). These findings should stimulate health-care workers to create specific groups for women, seroconcordant couples, and cannabis users to discuss condom use, as they seem to be vulnerable groups.

Objectives. The study aimed at describing characteristics and outcome of tuberculous meningitis (TBM) in HIV-positive patients and comparing these parameters with those of extrapulmonary TB (TBEP) and pulmonary TB (TBP). Methods. Kaplan-Meier estimation and Poisson regression models were used to assess the mortality following TB diagnosis and to evaluate potential prognostic factors for the 3 groups of TB patients separately. Results. A total of 100 patients with TBM, 601 with TBEP, and 371 TBP were included. Patients with TBM had lower CD4 cell counts and only 17.0% received antiretroviral therapy (ART) at TB diagnosis. The cumulative probability of death at 12 months following TB was 51.2% for TBM (95% CI 41.4–61.6%), 12.3% for TBP (8.9–15.7%), and 19.4% for TBEP (16.1–22.6) (P < 0.0001; log-rank test). For TBM, factors associated with a poorer prognosis were not being on ART (adjusted incidence rate ratio (aIRR) 4.00 (1.72–9.09), a prior AIDS diagnosis (aIRR = 4.82 (2.61–8.92)), and receiving care in Eastern Europe (aIRR = 5.41 (2.58–11.34))). Conclusions. TBM among HIV-positive patients was associated with a high mortality rate, especially for patients from Eastern Europe and patients with advanced HIV-infection, which urgently calls for public health interventions to improve both TB and HIV aspects of patient management.

Renal dysfunction is common in HIV-positive patients, and guidelines suggest regular monitoring of renal function with estimated glomerular filtration rate (eGFR) and urinalysis. It is unknown whether Chronic Kidney Disease Epidemiological Collaboration (CKD-EPI) or Modification of Diet in Renal Disease (MDRD) provide better estimates of glomerular filtration rate (GFR) in this population. We compared the CKD-EPI and MDRD equations to estimate GFR at baseline in 20,132 HIV-positive individuals in the UK CHIC cohort. Kappa statistics and Bland-Altman plots were used to assess agreement between the two estimates and Kaplan-Meier plots and Cox regression analysis to describe mortality patterns. At baseline, median eGFR was 100 (87, 112) (CKD-EPI) and 94 (83, 108) (MDRD) (mL/min/1.73 m(2)). Good overall agreement between CKD-EPI- and MDRD-defined eGFR bands was observed (Kappa = 0.71, 95% confidence interval: 0.70-0.72). Of the 367 patients with eGFR MDRD 30-59, 57 (15.5%) were categorized as eGFR 60-89 by CKD-EPI. After adjustment for covariates, eGFR <60 (CKD-EPI), eGFR <30 (MDRD) and eGFR ≥105 (both formulae) were significantly associated with an increased risk of death. Mortality in patients classified as having eGFR 60-89 by CKD-EPI and eGFR 30-59 by MDRD more closely resembled mortality of patients who had eGFR 60-89 by both formulae. MDRD and CKD-EPI equations showed a high degree of agreement in stratifying patients by baseline eGFR. CKD-EPI estimates of GFR <60 at baseline are more strongly associated with mortality than MDRD estimates of GFR <60, supporting the concept that MDRD may have overestimated the severity of renal impairment in these patients. Our findings support the use of CKD-EPI in HIV-positive individuals.

AIDS-associated disseminated Kaposi sarcoma (KS) is a rare entity, especially in India due to the low prevalence of human herpes virus-8 infections in Indian population. Due to its rapid and progressive nature, early diagnosis and institution of highly active antiretroviral therapy is crucial in AIDS-associated KS, with a view to achieving favorable prognosis. We report a case of disseminated KS in an HIV-1 positive patient, who presented with two months history of multiple violaceous patches and plaques over the trunk, bilateral upper limbs, lower limbs, and hard palate. The patient died of recurrent massive pleural effusion before starting antiretroviral therapy. This case is being reported due to the paucity of KS in the Indian literature, especially the disseminated type and to highlight its rapidly progressive course which can be fatal.

End-stage liver disease is emerging as a leading cause of death among HIV-positive patients. Historically, an HIV diagnosis was a contraindication for a liver transplant; however, because of the efficacy of highly active antiretroviral therapy (HAART), HIV-positive patients have one-year, two-year, and three-year post-transplantation survival rates similar to that of HIV-negative patients. Based on this evidence, HIV-positive patients are now considered eligible for transplantation. However, newly emerging guidelines include the stipulation that HIV-positive patients must be on HAART to be placed on a waiting list for transplantation. The purpose of the present paper is to evaluate the scientific and ethical probity of requiring HIV-positive patients to be on HAART as a condition for being on a liver transplant waiting list. It is argued that the emphasis should be placed on the probability of post-transplantation HAART tolerance, and that concerns about pretransplantation HAART tolerance are of secondary importance.

To examine changes in HIV-positive patient enrollment in a large health care delivery system before and after key Affordable Care Act (ACA) provisions went into effect in 2014. Analyses compared HIV-positive patients newly enrolled in Kaiser Permanente Northern California between January and June 2012 (n = 339) to those newly enrolled between January and June 2014 through the California insurance exchange or via other mechanisms (n = 549). After the ACA, the HIV-positive patient enrollment increased. These new enrollees were more likely to be male (93.6% vs 89.1%; P = .01), to be enrolled in high-deductible benefit plans (≥ $1000; 18.8% vs 5.5%; P = .01), and to have better HIV viral control (HIV RNA levels below limits of quantification 79.5% vs 73.6%; P = .05) compared with pre-ACA new enrollees. Among post-ACA new enrollees, there were more patients in the lowest and highest age groups. Post-ACA exchange enrollees (22%) were more likely to be male and to have high-deductible plans than those enrolled through other mechanisms. More men, higher deductibles, and better HIV viral control characterize newly enrolled HIV-positive patients after the ACA in California. Evolving characteristics of HIV-positive enrollees may affect HIV policy, patient care needs, and service utilization.

Cryptococcal meningitis (CM) is associated with substantial mortality in HIV-infected patients. Optimal timing of antiretroviral therapy (ART) in persons with CM represents a clinical challenge, and the burden of CM in Latin America has not been well described. Studies suggest that early ART initiation is associated with higher mortality, but data from the Americas are scarce. HIV-infected adults in care between 1985-2014 at participating sites in the Latin America (the Caribbean, Central and South America network (CCASAnet)) and the Vanderbilt Comprehensive Care Clinic (VCCC) and who had CM were included. Survival probabilities were estimated. Risk of death when initiating ART within the first 2 weeks after CM diagnosis versus initiating between 2-8 weeks was assessed using dynamic marginal structural models adjusting for site, age, sex, year of CM, CD4 count, and route of HIV transmission. 340 patients were included (Argentina 58, Brazil 138, Chile 28, Honduras 27, Mexico 34, VCCC 55) and 142 (42%) died during the observation period. Among 151 patients with CM prior to ART 56 (37%) patients died compared to 86 (45%) of 189 with CM after ART initiation (p=0.14). Patients diagnosed with CM after ART had a higher risk of death (p=0.03, log-rank test). The probability of survival was not statistically different between patients who started ART within 2 weeks of CM (7/24, 29%) vs. those initiating between 2-8 weeks (14/53, 26%) (p=0.96), potentially due to lack of power. In this large Latin-American cohort, patients with CM had very high mortality rates, especially those diagnosed after ART initiation. This study reflects the overwhelming burden of CM in HIV-infected patients in Latin America. Copyright © 2017 The Author(s). Published by Elsevier Ltd.. All rights reserved.

The presence of autonomic dysfunction in HIV patients is largely unknown. Early studies found autonomic dysfunction in patients with AIDS. Antiretroviral combination therapy (ART) has dramatically changed the course of the disease and improved prognosis and decreased morbidity. To evaluate whether autonomic dysfunction is present in an ART treated HIV population and if so to identify factors of importance. HIV patients receiving ART for at least 12 months (n = 97) and an age-matched control group of healthy volunteers (n = 52) were included. All were non-diabetic and had never received medication for hypertension. Following a 10 min resting period a 15 min ECG recording was performed. Heart-rate variability (HRV) analysis was performed in accordance with current guidelines and data reported as mean [interquartile range]. Mean normal-to-normal (NN) and total HRV measured as standard deviation of normal-to-normal (SDNN) was lower in HIV patients compared to controls (905 vs. 982 ms; p<0.001 and 48 vs. 54 ms; p = 0.028, respectively). No differences were found between the groups in parasympathetic activity measured as square root of the mean squared difference of successive NN-intervals (RMSSD) or the percent of differences between adjacent NN intervals greater than 50 ms (pNN50). In the HIV positives, haemoglobin A1c correlated inversely with SDNN, RMSSD and pNN50 (p<0.05). Total cholesterol and LDL-C correlated inversely with RMSSD and pNN50 (p<0.05). Neither HIV duration, HIV-RNA, CD4 cell count nor CD4 nadir correlated with time or phase domain HRV variables. Moderate autonomic dysfunction is present in HIV positives patients even with suppressed viral load due to ART. The dysfunction is correlated with HbA1c and hypercholesterolemia but not to duration of HIV or whether the patients were receiving protease inhibitors as part of the ART regime.

Anemia, which may develop due to direct effect of the virus or indirect effect of zidovudine a widely used antiviral agent for the treatment, is not an uncommon complication in human immundeficiency virus (HIV) infections. In this report, a 26 years old male HIV positive patient who developed rapid anemia in the HAART (Highly active anti-retroviral therapy) protocol including zidovudine, was presented. The patient has been followed since May 2003 without anti-retroviral therapy. He was diagnosed as alpha-thalassemia trait, because of the low mean red blood cell volume (MCV), high red blood cell count and living in an Mediterranian country. However, no treatment for thalassemia had been given in this period, since the other laboratory findings [hemoglobin, hematocrit, red cell distribution width index (RDWI), iron and iron binding capacity, transferrin saturation and ferritin levels] were normal. During the follow-up of patient, HAART protocol with zidovudine, lamivudine and indinavir, was started depending on the findings of low CD4+ T-cell count (443/mm3) and high HIV serum load (1,330,000 copies/ml). In the second month of the therapy the hemoglobin level decreased to 12.9 gr/dL, and then to 9.9 gr/dL in the fourth month, while it was 14.5 gr/dL before anti-retroviral therapy. Although the patient had no hemolysis findings, and his serum folic acid level was normal, folbiol treatment was initiated with the possibility of the presence of folic acid deficiency at cellular level. Anemia resolved with folic acid replacement without discontinuation of zidovudine or a reduction in dosage. It was thought that the presence of alpha-thalassemia co-morbidity has facilitated the development of anti-retroviral-induced anemia in this patient. As a result, it is concluded that thalassemia should be considered in the differential diagnosis of anemia in HIV positive patients, especially for the ones from Mediterranian countries.

Background: Treatment failure (TF) in patients receiving antiretroviral therapy against human immunodeficiency virus (HIV) is always a concern. Objective: To examine the correlates associated with TF in patients living in the Colombian Caribbean city of Barranquilla, an aspect that was poorly studied in this region. Methods: Treatment failure was evaluated in a cross-sectional study from virological, immunological and clinical standpoints. Results: It was established that 29.5% of patients under highly active antiretroviral therapy (ART) could be considered in TF. Among those, virological failure was most frequent (20.9%), followed by immunological- (14.0%) and clinical failure (4.7%). In patients showing lack of adherence to the treatment, the likelihood of suffering from TF and virogical failure were respectively increased by 6.67-fold and 12.19-fold, compared with patients showing good adherence. Although there was no statistically significant association, TF tended to be more frequent in young adults, in patients with low income and, low level of education. When ART regimens were compared, there was no apparent difference in TF between regimens based on non-nucleoside reverse transcriptase inhibitors and those based on protease inhibitors. This is very important in the context of recent ART strategies, such as early-initiated ART, aimed at achieving long-term infection control. Conclusions: Is confirmed the importance of treatment adherence to avoid TF and further highlights the importance of educating HIV-infected patients in all parts of the world, especially those individuals with a lower socio-economic status.

HIV cohort collaborations, which pool data from diverse patient cohorts, have provided key insights into outcomes of antiretroviral therapy (ART). However, the extent of, and reasons for, between-cohort heterogeneity in rates of AIDS and mortality are unclear. We obtained data on adult HIV-positive patients who started ART from 1998 without a previous AIDS diagnosis from 17 cohorts in North America and Europe. Patients were followed up from 1 month to 2 years after starting ART. We examined between-cohort heterogeneity in crude and adjusted (age, sex, HIV transmission risk, year, CD4 count and HIV-1 RNA at start of ART) rates of AIDS and mortality using random-effects meta-analysis and meta-regression. During 61 520 person-years, 754/38 706 (1.9%) patients died and 1890 (4.9%) progressed to AIDS. Between-cohort variance in mortality rates was reduced from 0.84 to 0.24 (0.73 to 0.28 for AIDS rates) after adjustment for patient characteristics. Adjusted mortality rates were inversely associated with cohorts' estimated completeness of death ascertainment [excellent: 96-100%, good: 90-95%, average: 75-89%; mortality rate ratio 0.66 (95% confidence interval 0.46-0.94) per category]. Mortality rate ratios comparing Europe with North America were 0.42 (0.31-0.57) before and 0.47 (0.30-0.73) after adjusting for completeness of ascertainment. Heterogeneity between settings in outcomes of HIV treatment has implications for collaborative analyses, policy and clinical care. Estimated mortality rates may require adjustment for completeness of ascertainment. Higher mortality rate in North American, compared with European, cohorts was not fully explained by completeness of ascertainment and may be because of the inclusion of more socially marginalized patients with higher mortality risk.

Cigarette smoking is increasingly recognized as an indicator for inferior adherence to antiretroviral therapy (ART) among HIV-positive patients. Given the limited body of work on this issue, we aimed to explore the relations between cigarette smoking, nicotine dependence, and ART adherence in Vietnam. A cross-sectional study of 1050 HIV-positive people was conducted from January to September 2013 in Hanoi (the capital) and Nam Dinh (a rural city). Adherence to ART during the last 30 days was measured by the 100-point visual analog scale (VAS). Smoking history and nicotine dependence (Fagerstrom Test of Nicotine Dependence) were self-reported by participants. Multiple logistic regression was performed to examine the association of current smoking and nicotine dependence with ART nonadherence. Using the established VAS cut point of 95 to indicate adequate adherence, the prevalence of ART nonadherence was 30.9%. Approximately 35.5% of the sample reported current smoking. No association between smoking status and ART nonadherence was found. However, participants with greater nicotine dependence (OR = 1.1, 95%CI = 1.0-1.2 per unit increase) were more likely to be nonadherent. Also, individuals who were female (OR = 1.70, 95%CI = 1.19-2.42), receiving ART in Nam Dinh (OR = 1.6, 95%CI = 1.1-2.4), and currently feeling anxiety (OR = 1.6, 95% CI = 1.2-2.1) had a higher likelihood of ART nonadherence. Additionally, current smokers reporting current pain (OR = 1.9, 95%CI = 1.2-3.1) were more likely to be nonadherent. Conversely, protective factors included living with a spouse/partner (OR = 0.5, 95%CI = 0.3-0.7) and having more than a high school education (OR = 0.4, 95%CI = 0.1-1.0). Given the high prevalence of suboptimal adherence and current smoking among HIV-positive patients, screening for smoking status and nicotine dependence during ART treatment may help to improve patients' adherence to medication.

We surveyed the HIV-positive population attending a major teaching hospital sited outwith a major conurbation. Eighty-five percent of homosexually acquired infections were contracted within the UK and 91% of heterosexually acquired infections were contracted outside of the UK. A strikingly wide range of nationalities (45) and countries of origin of infection were represented within a relatively small patient population. Most patients were non-UK-born immigrants. A high proportion of illegal immigrants were identified within which there was a high proportion lost to follow-up. This degree of ethnic diversity and domiciliary instability is rarely a feature of non-HIV populations in this setting and imposes additional demands on delivery of care and health-care planning.

Penicilliosis is a disseminated and progressive infection that is mainly found in immunocompromised individuals, especially those with human immunodeficiency virus (HIV) infection. Because of the high mortality of patients with disseminated Penicillium marneffei infection, rapid diagnosis and early treatment are required. Diagnosis is traditionally made by biopsy and/or culture of blood or any involved organ. Cytology offers several advantages over biopsy, including more rapid diagnosis and greater resolution of cytomorphologic details of organisms, allowing rapid initiation of treatment. Here, we describe a case of penicilliosis in an HIV-positive patient with emphasis on the morphological characteristics of the organism in cytologic specimens, as well as a comparison of bronchial washing and biopsy findings.

Candida species are a common cause of infection in immune-compromised HIV-positive individuals, who are usually treated with the antifungal drug, fluconazole, in public hospitals in Africa. However, information about the prevalence of drug resistance to fluconazole and other antifungal agents on Candida species is very limited. This study examined 128 Candida isolates from South Africa and 126 Cameroonian Candida isolates for determination of species prevalence and antifungal drug susceptibility. The isolates were characterized by growth on chromogenic and selective media and by their susceptibility to 9 antifungal drugs tested using the TREK™ YeastOne9 drug panel (Thermo Scientific, USA). Eighty-three percent (82.8%) of South African isolates were Candida albicans (106 isolates), 9.4% were Candida glabrata (12 isolates), and 7.8% were Candida dubliniensis (10 isolates). Of the Cameroonian isolates, 73.02% were C. albicans (92 isolates); 19.05% C. glabrata (24 isolates); 3.2% Candida tropicalis (4 isolates); 2.4% Candida krusei (3 isolates); 1.59% either Candida kefyr, Candida parapsilopsis, or Candida lusitaneae (2 isolates); and 0.79% C. dubliniensis (1 isolate). Widespread C. albicans resistance to azoles was detected phenotypically in both populations. Differences in drug resistance were seen within C. glabrata found in both populations. Echinocandin drugs were more effective on isolates obtained from the Cameroon than in South Africa. A multiple-drug resistant C. dubliniensis strain isolated from the South African samples was inhibited only by 5-flucytosine in vitro on the YO9 panel. Drug resistance among oral Candida species is common among African HIV patients in these 2 countries. Regional surveillance of Candida species drug susceptibility should be undertaken to ensure effective treatment for HIV-positive patients. Copyright © 2014 Elsevier Inc. All rights reserved.

Our objective was to determine the seroprevalence of syphilis among HIV-infected patients in a tertiary care hospital in Mexico City. A cross-sectional study was developed, and 318 HIV-positive patients were evaluated from January to February 2013 at Hospital de Infectología, National Medical Center 'La Raza' (a tertiary care hospital specialising in infectious diseases in Mexico City). Laboratory data were screened for the detection of antibodies against Treponema pallidum. Patients completed a questionnaire relating to socio-demographic data and factors associated with syphilis. Of the 318 patients, 83% were men. The mean age ± SD was 36 ± 11 years; 52% were men who have sex with men and 47% had undertaken higher education. The overall seroprevalence of syphilis among these patients was 25% (95% confidence interval 21%, 30%). Men who have sex with men had a significantly higher seroprevalence (30% vs. 15%, p = 0.009). We conclude that, in Mexico, there is a high seroprevalence of syphilis antibodies in HIV-infected patients and that men who have sex with men are the group most affected.

The presence of autonomic dysfunction in HIV patients is largely unknown. Early studies found autonomic dysfunction in patients with AIDS. Antiretroviral combination therapy (ART) has dramatically changed the course of the disease and improved prognosis and decreased morbidity. Aim To evaluate whether autonomic dysfunction is present in an ART treated HIV population and if so to identify factors of importance. Methods HIV patients receiving ART for at least 12 months (n = 97) and an age-matched control group of healthy volunteers (n = 52) were included. All were non-diabetic and had never received medication for hypertension. Following a 10 min resting period a 15 min ECG recording was performed. Heart-rate variability (HRV) analysis was performed in accordance with current guidelines and data reported as mean [interquartile range]. Results Mean normal-to-normal (NN) and total HRV measured as standard deviation of normal-to-normal (SDNN) was lower in HIV patients compared to controls (905 vs. 982 ms; p<0.001 and 48 vs. 54 ms; p = 0.028, respectively). No differences were found between the groups in parasympathetic activity measured as square root of the mean squared difference of successive NN-intervals (RMSSD) or the percent of differences between adjacent NN intervals greater than 50 ms (pNN50). In the HIV positives, haemoglobin A1c correlated inversely with SDNN, RMSSD and pNN50 (p<0.05). Total cholesterol and LDL-C correlated inversely with RMSSD and pNN50 (p<0.05). Neither HIV duration, HIV-RNA, CD4 cell count nor CD4 nadir correlated with time or phase domain HRV variables. Conclusions Moderate autonomic dysfunction is present in HIV positives patients even with suppressed viral load due to ART. The dysfunction is correlated with HbA1c and hypercholesterolemia but not to duration of HIV or whether the patients were receiving protease inhibitors as part of the ART regime. PMID:21655281

Considering that there are some studies with autopsies from AIDS describing only malignant neoplasias and that changes can occur after the introduction of Highly Active Antiretroviral Therapy (HAART), our objectives were to analyze the frequency of benign and malignant neoplasms in AIDS patients in the periods of both pre- and post-HAART. This is a retrospective study with 261 autopsies of HIV-positive patients between 1989 and 2008 in Uberaba, Brazil. Sixty-six neoplasms were found (39 benign, 21 malignant and six premalignant) in 58 patients. The most frequent malignant neoplasms were lymphoid, in 2.7% (four Non-Hodgkin lymphoma, one Hodgkin, one multiple myeloma and one plasmablastic plasmacytoma), and Kaposi's Sarcoma, in 2.3% (six cases). The most frequent benign neoplasms were hepatic hemangiomas in 11 (4.2%) of 261 cases and uterine leiomyoma in 11 (15.7%) of 70 woman. In the pre-HAART period eight (9.8%) benign neoplasias and four (4.9%) malignant occurred in 82 patients; in the post-HAART period, 29 (16.2%) benign and 17 (9.5%) malignant were present; however, the differences were not significant. We conclude that the introduction of HAART in our region doesn't look to have modified the frequency of neoplasms occurring in patients with HIV.

Opportunistic infections are the main cause of morbidity and death among HIV-positive patients. Most of these infections are linked to the immunodeficiency due to low CD4+ counts. However, not all patients with low CD4+ counts are equally susceptible to infections, and we hypothesize that variability in genes of innate immunity may also play an important role. The dectin-1/CARD9 pathway is crucial for recognition of both fungal and bacterial pathogens. The aim of this study was to assess the possible association between the occurrence of opportunistic infections and single nucleotide polymorphisms in DECTIN-1 and CARD9 in a cohort of 187 HIV-infected patients. The incidence of oropharyngeal candidiasis and other opportunistic infections was not influenced by either the Y238X DECTIN-1 or the S12N CARD9 polymorphism. Surprisingly however, the prevalence of pneumonia was significantly higher in patients bearing the defective variant DECTIN-1 allele. These results suggest a role of dectin-1 in the host defense against respiratory bacterial infections, and future studies are warranted to confirm this association.

This study examined the association between socio-demographic factors (educational level and employment status) and the nutritional and immune status of 35 HIV-positive/AIDS patients at baseline. Assessment of selected macro-and micronutrient dietary intake was done using a validated food frequency questionnaire. Evaluation of anthropometric profiles (body mass index, waist-hip ratio and percentage of body fat) was also evaluated. A questionnaire was applied to obtain information on the educational level and employment status of the patients. The CD4+ T-cell counts and viral loads of the same patients were determined using the flow cytometry and Polymerase Chain Reaction (PCR) method respectively. An association between educational level and dietary intake was significant (p < 0.05) for total dietary fibre, selenium and vitamin C. There was no significant (p > 0.05) association between the two socio-demographic variables (education and employment) and anthropometric profiles. The association between education, employment and CD4+ T-cell count was not significant (p > 0.05). The viral load showed a significant (p < 0.05) association with employment status but not correlated with education. The sample size or certain inherent biological and social factors probably affected the outcomes of the interplay between the two selected socio-demographic factors and the nutritional and immune status. It is suggested that the results of this study should be interpreted with caution. Further studies with larger sample sizes are recommended.

Anal cancer is biological similar to cervical cancer, and is preceded by anal intraepithelial neoplasia (AIN). Screening for AIN and treatments to reduce the risk of anal cancer are not established as guidelines of care for HIV-infected patients. It is mainly because screening and treating of AIN is not yet proven to reduce the incidence of anal cancer. The present study preliminarily demonstrated that a successful screening program in preventing squamous cell anal cancer in HIV positive patients. The authors achieved their purpose of controlling the evolution of all abnormalities identified during the anal cancer screening, preventing AIN to progress towards anal cancer, and reversing any form of AIN by surgery, ablation or medical therapy. Randomized controlled multi-center trials with a large sample size should be carried out to validate the study results. It is wise for the physicians to actively screen and treat AIN in HIV-infected patients whenever possible unless the results of randomized controlled study demonstrate that doing so is inappropriate.

The purpose of this study was to describe the occurrence of a retinal pigment epitheliopathy associated with macular telangiectasis and intraretinal crystal deposits in three human immunodeficiency virus-positive patients receiving long-term ritonavir as part of highly active antiretroviral therapy. The patient's records were reviewed. The CD4 T-cell counts at presentation were 163 cells per microliter, 464 cells per microliter, and 349 cells per microliter, and viral loads were undetectable in all patients. None of the patients had a concurrent AIDS-defining illness. Other significant medical history included hyperlipidemia in one patient and a remote history of lymphoma and tuberculosis in a second patient. Initial visual acuity ranged from 20/32 to 20/400, with a median of 20/150. Anterior segment examination and intraocular pressures were normal in all eyes. Posterior segment examination revealed bilateral macular retinal pigment epitheliopathy with intraretinal crystalline deposits. No hemorrhage or cotton wool spots were seen consistent with human immunodeficiency virus retinopathy, and there was no evidence of previous or active cystomegalovirus retinitis. Fluorescein angiography revealed parafoveal telangiectasis with late leakage in two of the three patients. Optical coherence tomography showed thickening of the macula in three eyes and inner foveal cysts in two eyes. Autofluorescence performed on one patient revealed complete loss of normal retinal pigment epithelium autofluorescence corresponding to the area of retinal pigment epitheliopathy bilaterally. The only medicine common to all 3 patients was ritonavir, and the duration of ritonavir therapy before presentation was 19 months in one patient, 30 months in the second patient, and 5 years in the third patient. Retinal changes characterized by retinal pigment epitheliopathy, parafoveal telangiectasias, and intraretinal crystal deposits occurred in three human immunodeficiency virus-positive patients on

Potential screening modalities for early diagnosis of squamous cell anal cancer (SCC) in HIV patients include digital anorectal examination (DARE), anal Papanicolaou testing (Pap test), human papilloma virus (HPV) co-testing, and high-resolution anoscopy. The aim of this study was to demonstrate the results of a five-year screening program for SCC in HIV patients. We conducted a retrospective study on 204 HIV patients who underwent a screening program for SCC from October 2010 to January 2015. All patients were screened by DARE, anal Pap test, including HPV test and cytology, and high-resolution video-proctoscopy (HR-VPS) with and without acetic acid 3%. Depending on macroscopic appearance and biopsies, patients underwent observation or treatment. Median follow-up was 36 months. Cytologic abnormalities (Cyt+) for high-risk HPV genotypes were recorded in 34% of patients. HR-VPS was positive in 59 patients (29%), of whom 13 patients (22%) were positive for warts; the rest have typical features of anal intraepithelial neoplasia (AIN). Sixteen (8%) patients had AIN (AIN I-III) and underwent wide local excision, ablation, or imiquimod. Absence of progression was recorded. Fourteen patients (7%) had SCC: eight (57%) with no evidence of recurrence, two (14%) had recurrence, and four (29%) died from metastatic disease. Our data demonstrated a successful screening program in preventing SCC in HIV patients. We demonstrate the advantages of progression towards SCC. Moreover, we used a new screening tool, the HR-VPS, a low-cost and manageable instrument to collect patients' long-term data.

Microsporidioses are considered emerging and opportunistic infections in immunocompromised individuals worldwide. The purpose of this study was to identify the species of intestinal microsporidia in patients with HIV-AIDS from the Servicio Autónomo Hospital Universitario de Maracaibo, Venezuela (SAHUM). Fecal samples were collected from 50 patients with confirmed diagnosis of HIV, during the years 2007 and 2008; the CD4 values were obtained from 42 patients. The samples were analyzed by separate PCRs to identify Encephalitozoon intestinalis and Enterocytozoon bieneusi. Microsporidia species showed a 36% prevalence: ten patients had Encephalitozoon intestinalis, four Enterocytozoon bieneusi and four both species. An inverse and statistically significant relationship between the CD4 count and the presence of microsporidia in the fecal sample was also found. It is remarkable the high prevalence of microsporidia species observed in the HIV patients studied, with a predominance of E. intestinalis.

Patients infected with HIV are at increased risk for cardiovascular disease despite successful antiretroviral therapy. Likewise, chronic hepatitis C virus (HCV) infection is associated with extrahepatic complications, including cardiovascular disease. However the risk of cardiovascular disease has not been formally examined in HIV/HCV-coinfected patients. A retrospective study was carried out to assess the influence of HCV coinfection on the risk of cardiovascular events in a large cohort of HIV-infected patients recruited since year 2004. A composite event of cardiovascular disease was used as an endpoint, including myocardial infarction, angina pectoris, stroke or death due to any of them. A total of 1136 patients (567 HIV-monoinfected, 70 HCV-monoinfected and 499 HIV/HCV-coinfected) were analysed. Mean age was 42.7 years, 79% were males, and 46% were former injection drug users. Over a mean follow-up of 79.4 ± 21 months, 3 patients died due to cardiovascular disease, whereas 29 suffered a first episode of coronary ischaemia or stroke. HIV/HCV-coinfected patients had a greater incidence of cardiovascular disease events and/or death than HIV-monoinfected individuals (4% vs 1.2%, P = 0.004) and HCV-monoinfected persons (4% vs 1.4%, P = 0.5). After adjusting for demographics, virological parameters and classical cardiovascular disease risk factors (smoking, hypertension, diabetes, high LDL cholesterol), both HIV/HCV coinfection (HR 2.91; CI 95%: 1.19-7.12; P = 0.02) and hypertension (HR 3.65; CI 95%: 1.34-9.94; P = 0.01) were independently associated with cardiovascular disease events and/or death in HIV-infected patients. Chronic hepatitis C and hypertension are independently associated with increased cardiovascular disease risk in HIV-infected patients. Therefore, treatment of chronic hepatitis C should be prioritized in HIV/HCV-coinfected patients regardless of any liver fibrosis staging.

Background HIV infection is associated with an increased risk of cardiovascular disease (CVD). Chronic low-grade immune activation is likely one of the driving mechanisms. This systematic review provides an overview of the evidence addressing the relation between immune markers and surrogate markers of CVD (except CIMT) in HIV infection. Methods A systematic search was performed in PubMed, Embase and Cochrane Library identifying all articles from 1996 to April 2015. It addressed the relation between immune markers and surrogate markers of CVD (except Carotid Intima-media Thickness) in HIV-positive adults. Two authors, using predefined criteria, independently conducted the selection of articles, critical appraisal and extraction of the data. Analysis focused on immune markers that were assessed most frequently. The review was conducted according to the PRISMA guideline and performed as part of an overarching review registered with PROSPERO (CRD42014010516). Findings Twenty-nine articles were selected, describing 34 immune markers and nine different CVD surrogate outcomes: coronary calcium score (13 times) and flow-mediated dilation (10 times) were used most frequently. Twenty-seven studies had a cross-sectional design. CRP, IL-6 and sVCAM-1 were assessed most frequently. None of the immune markers were clearly associated with any of the surrogate CVD outcomes. No effect estimate could be calculated due to marked heterogeneity in study populations, immune markers, outcomes and statistical approaches. Interpretation This review could not identify a clear association between any of the immune markers and surrogate CVD outcomes. This may reflect a true lack of association, or may be explained by heterogeneity across studies and lack of follow-up data. Future research should focus on longitudinal studies measuring a select set of immune markers and surrogate CVD outcomes awaiting the primary outcome of clinical cardiovascular events. PMID:28085961

Medication adherence remains a critical link between the prescribed ART regimen and treatment outcome. Several factors may influence adherence behavior. This cross-sectional study aimed to highlight socioeconomic predictors of adherence behavior among a cohort of 242 adult Malaysian patients receiving antiretroviral therapy in Hospital Sungai Buloh, Malaysia, where they were enrolled in a parent study (single-blinded randomized controlled trial) between January and December 2014. Statistical analysis of secondary data on adherence behavior and sociodemographic characteristics of the patients revealed mean age of 33.4 years and ranged from 18 to 64 years; 88.8% were males. A total of 224 (93%) patients who completed 6 months' adherence assessment were included in the model. Of these, 135 (60.3%) achieved optimal adherence. Multivariate binary logistic regression analysis revealed that patient's income and ethnicity were significant predictors of adherence behavior. This may be valuable for targeted programmatic interventions to further enhance successful treatment outcomes among the target population.

An audit of upper gastrointestinal endoscopy in HIV infected patients with gastrointestinal symptoms assessed the frequency of disease detected by endoscopy and routine laboratory analysis of surveillance biopsy specimens. Sixty nine consecutive endoscopies were performed in 59 HIV infected patients. Endoscopic biopsy specimens were taken from the lower oesophagus, gastric antrum, and third part of the duodenum for virology, histopathology, parasitology, bacteriology, and mycobacterial culture. Endoscopic appearances detected disease in 25/59 (42.4%) patients (oesophageal candida, 14; oesophageal ulcer, 3; Kaposi's sarcoma, 4; others, 4), but only 4/43 (9.3%) specimens showed evidence of disease in the absence of endoscopic abnormality. Virology for cytomegalovirus (detection of early antigenic fluorescent foci and culture) was positive in 6/59 (10.2%) patients, but parasitology and mycobacterial culture were negative in all cases. Histopathology was abnormal in 11/52 (21%) oesophageal biopsy specimens, 13/47 (28%) gastric biopsy specimens, and 4/65 (6%) duodenal biopsy specimens. Abnormal findings were found predominantly in those with advanced HIV disease (CDC Stage IV) (21/33 patients (64%)) compared with those with early HIV disease (CDC Stage II) (5/26 (19%)). In conclusion, upper gastrointestinal endoscopy detects macroscopic disease in AIDS patients and those with low CD4 counts, but routine surveillance biopsy specimens of apparently normal bowel in early HIV disease (or where CD4 counts are greater than 0.2 x 10(9)/1) are of little value.

Contexte : Le centre de santé Emakhandeni, qui offre une prise en charge de la tuberculose (TB) et du virus de l'immunodéficience humaine (VIH) décentralisée et intégrée à Bulawayo, Zimbabwe.Objectifs : Comparer la prise en charge du VIH pour les patients présumés tuberculeux, avec et sans TB, enregistrés en 2013.Schéma : Etude rétrospective de cohorte basée sur les données de routine du programme.Résultats: Sur 422 patients présumés tuberculeux enregistrés, 26% étaient connus comme VIH positifs. Parmi les 315 patients restants, 255 (81%) ont eu un test VIH, dont 190 (75%) se sont avérés positifs. Parmi eux, 26% ont eu un diagnostic de TB et 71% n'ont pas été confirmés tuberculeux (les 3% restants n'ont eu aucun résultat de TB enregistré). Pour les 134 patients sans TB, les données d'éligibilité au traitement antirétroviral (ART) ont été notées chez 42 (31%) patients et 95% ont été éligibles à l'ART. La mise en œuvre du traitement préventif par cotrimoxazole (CPT) et l'ART a été notée pour respectivement 88% et 90% des patients VIH positifs avec TB, comparés à respectivement 40% et 38% des patients VIH positifs sans TB (P < 0,001).Conclusion : Les patients présumés TB mais non confirmés avaient un taux élevé de positivité au VIH et pour ceux dont les données étaient disponibles, la majorité était éligible à l'ART. Par contre, pour les patients VIH positifs sans une TB confirmée, le taux de mise en œuvre du traitement préventif par CPT et de l'ART a été médiocre. Une approche « tester et traiter » et de meilleurs liens entre les services pourraient sauver la vie de ces patients, surtout en Afrique australe où les taux de VIH et de TB sont très élevés.

Introduction We designed a randomized, controlled prospective study aimed at comparing efficacy and tolerability of ezetimibe+fenofibrate treatment versus pravastatin monotherapy in dyslipidemic HIV-positive (HIV+) patients treated with protease inhibitors (PIs). Methods We consecutively enrolled 42 HIV+ dyslipidemic patients on stable PIs therapy (LDL cholesterol >130 mg/dl or triglycerides 200–500 mg/dl with non-HDL cholesterol >160 mg/dl). After basal evaluation, patients were randomized to a six-month treatment with ezetimibe 10 mg/day+fenofibrate 200 mg/day or with pravastatin 40 mg/day. Both at the basal evaluation and after the six-month treatment, the patients underwent blood tests for lipid parameters, and muscle and liver enzymes. Results At baseline, the two groups (21 patients each) were similar with regards to gender, age, BMI, blood pressure and virologic and metabolic parameters. After the six-month therapy, total cholesterol, LDL cholesterol and non-HDL cholesterol decreased significantly (p<0.01) in both groups. high-density lipoprotein (HDL) cholesterol increased (44±10 to 53±12 mg/dl, p<0.005) and triglycerides decreased (from 265±118 mg/dl to 149±37 mg/dl, p<0.001) in the ezetimibe+fenofibrate group, whereas both parameters remained unchanged in the pravastatin group. Mean values of creatine kinase (CK), alanine aminotransferase and aspartate aminotransferase were unchanged in both groups; only one patient in the pravastatin group stopped the treatment after two months, due to increased CK. Conclusions In dyslipidemic HIV+ patients on PI therapy, the association of ezetimibe+fenofibrate is more effective than pravastatin monotherapy in improving lipid profile and is also well tolerated.

Summary Concerns regarding possible interactions between midazolam and antiretroviral medicines have caused clinicians to use second-line sedatives, such as diazepam, instead. We demonstrated that patients who received midazolam during colonoscopy had similar clinical outcomes as those who received diazepam. Background Because of concerns regarding interactions between midazolam and antiretroviral therapy (ART), alternative sedatives are sometimes used during procedural sedation. Our objective was to compare outcomes in patients on ART who received intravenous (IV) midazolam versus IV diazepam, a second-line agent, during colonoscopy. Methods We conducted a retrospective analysis of adult HIV-infected patients who underwent colonoscopy over a 3.5-year period. Primary outcomes were sedation duration, nadir systolic blood pressure, nadir oxygen saturation, abnormal cardiac rhythm, and change in level of consciousness using a standardized scale. We calculated rates of adverse events according to benzodiazepine use and identified risk factors for complications using univariate and multivariate analyses. Results We identified 136 patients for this analysis: 70 received midazolam-based sedation and 66 received a diazepam-based regimen. There were no significant differences between the two groups with respect to sedation duration (48 versus 45.7 minutes, P = 0.68), nadir systolic blood pressure (97 versus 101.6 mmHg, P = 0.06), nadir oxygen saturation (94.6 versus 94.8%, P = 0.72), or rate of abnormal cardiac rhythm (11.4 versus 19.7%, P = 0.18). More patients in the midazolam group experienced a depressed level of consciousness (91 versus 74%, P = 0.0075), but no patient required reversal of sedation or became unresponsive. Conclusions Although IV midazolam interacts with ART, we did not find evidence that patients who received this agent for procedural sedation had clinical outcomes statistically different from those who received diazepam. These findings should be

Cryptococcal immune reconstitution inflammatory syndrome (C-IRIS) is an increasingly important manifestation among patients with HIV/AIDS, especially as the use of antiretroviral therapy (ART) is expanding worldwide. Cryptococcus and associated C-IRIS are common causes of meningitis. While intracranial lesions are common in HIV/AIDS, they are rarely due to cryptococcosis or C-IRIS. We describe two cases of paradoxical C-IRIS associated with the development of intracranial cryptococcomas in HIV/AIDS. Both patients had an initial episode of cryptococcal meningitis treated with antifungal therapy. At the time, they had initiated or modified ART with subsequent evidence of immune reconstitution. Two months later, they developed aseptic meningitis with intracranial lesions. After exhaustive work ups, both patients were diagnosed with paradoxical C-IRIS and biopsy confirmed intracranial cryptococcomas. We review the important clinical, diagnostic and therapeutic features of cryptococcomas associated with C-IRIS in HIV/AIDS.

A major problem impeding development of an effective HIV vaccine is the rapid antigenic variability that is characteristic of several envelope glycoprotein epitopes. Frequent mutations alter the composition of the most immunogenic regions of the envelope glycoprotein. We have prepared a synthetic immunogen representing the evolution of the major hypervariable epitopes on the envelope glycoprotein (gp120) of HIV-1. Five synthetic constructs, representing each of the HIV-1 gp120 hypervariable epitopes were tested for recognition by antibodies from patients infected with HIV-1 from different geographic regions worldwide. An HIV-1 human plasma panel provided a representation of the antibodies recognizing subtype-specific epitope sequences prevalent at different parts of the world. The vaccine construct was recognized by antibodies from HIV-1-positive individuals infected with subtypes A, B, C, D, E, and F. Antibodies in pooled HIV-1 patient sera from San Francisco also recognized all five constructs. This complex immunogen was recognized by antibodies in sera from individual HIV-1-positive and AIDS patients from Puerto Rico and Canada, with a strong binding to the complete vaccine and the V3 component. Altogether, our results demonstrate that antibodies from seropositive patients infected with different HIV-1 clades recognize and bind to the HIV hypervariable epitope construct vaccine preparation and its individual components.

Objectives To estimate mortality rates and prognostic factors in HIV-positive patients who started combination antiretroviral therapy between 1996–1999 and survived for more than ten years. Methods We used data from 18 European and North American HIV cohort studies contributing to the Antiretroviral Therapy Cohort Collaboration. We followed up patients from ten years after start of combination antiretroviral therapy. We estimated overall and cause-specific mortality rate ratios for age, sex, transmission through injection drug use, AIDS, CD4 count and HIV-1 RNA. Results During 50,593 person years 656/13,011 (5%) patients died. Older age, male sex, injecting drug use transmission, AIDS, and low CD4 count and detectable viral replication ten years after starting combination antiretroviral therapy were associated with higher subsequent mortality. CD4 count at ART start did not predict mortality in models adjusted for patient characteristics ten years after start of antiretroviral therapy. The most frequent causes of death (among 340 classified) were non-AIDS cancer, AIDS, cardiovascular, and liver-related disease. Older age was strongly associated with cardiovascular mortality, injecting drug use transmission with non-AIDS infection and liver-related mortality, and low CD4 and detectable viral replication ten years after starting antiretroviral therapy with AIDS mortality. Five-year mortality risk was <5% in 60% of all patients, and in 30% of those aged over 60 years. Conclusions Viral replication, lower CD4 count, prior AIDS, and transmission via injecting drug use continue to predict higher all-cause and AIDS-related mortality in patients treated with combination antiretroviral therapy for over a decade. Deaths from AIDS and non-AIDS infection are less frequent than deaths from other non-AIDS causes. PMID:27525413

Introduction Previous studies, mostly from Africa, have shown that serum cryptococcal antigenemia may precede the development of cryptococcal meningitis and early death among patients with advanced HIV infection. We examined cryptococcal antigenemia as a risk factor for HIV-associated mortality in Indonesia, which is experiencing a rapidly growing HIV epidemic. Methods We included ART-naïve HIV patients with a CD4 cell count below 100 cells/μL and no signs of meningitis in an outpatient HIV clinic in Bandung, West Java, Indonesia. Baseline clinical data and follow-up were retrieved from a prospective database, and cryptococcal antigen was measured in stored serum samples using a semiquantitative lateral flow assay. Cox regression analysis was used to identify factors related to mortality. Results Among 810 patients (median CD4 cell count 22), 58 (7.1%) had a positive cryptococcal antigen test with a median titre of 1:80 (range: 1:1 to 1:2560). Cryptococcal antigenemia at baseline was strongly associated with the development of cryptococcal meningitis and early death and loss to follow-up. After one year, both death (22.4% vs. 11.6%; p=0.016; adjusted HR 2.19; 95% CI 1.78–4.06) and the combined endpoint of death or loss to follow-up (67.2% vs. 40.4%; p<0.001; adjusted HR 1.57; 95% CI 1.12–2.20) were significantly higher among patients with a positive cryptococcal antigen test. Conclusions Cryptococcal antigenemia is common and clinically relevant among patients with advanced HIV in this setting. Routine screening for cryptococcal antigen followed by lumbar puncture and pre-emptive antifungal treatment for those who are positive may help in reducing early mortality. PMID:24476751

We report a case of human herpes virus-8-associated multicentric Castleman's disease in an HIV-positive patient with hyponatraemia. A 65-year-old man was admitted with relapsing and remitting fever, scattered skin eruptions and hepatosplenomegaly following combination antiretroviral therapy for his HIV infection. Based on histopathological findings, he was diagnosed as having human herpes virus-8-associated multicentric Castleman's disease and was treated with four-weekly infusions of rituximab. Prior to receiving chemotherapy, we observed several suspected biomarkers of disease activity, positive correlations between plasma human herpes virus-8 viral load and the levels of plasma interleukin-6, C-reactive protein and soluble interleukin-2 receptor, and negative correlations between platelet count, albumin levels and especially serum sodium levels. We hypothesize that non-osmotic release of plasma antidiuretic hormone is a cause of hyponatraemia in human herpes virus-8-associated multicentric Castleman's disease and that relapsing and remitting hyponatraemia could be correlated with plasma human herpes virus-8 viral load.

Isolated iliac artery aneurysms are a rare entity. The majority of cases are asymptomatic and often escape detection. Mortality rates after sudden rupture and emergent surgery for iliac artery aneurysm are very high. We report a case of a 56-year-old man who presented with right hip pain masquerading as septic arthritis or psoas abscess. CT showed ruptured right common iliac artery aneurysm with extensive active extravasation into psoas with a retroperitoneal haematoma. Aneurysm was repaired using an endovascular technique. Postoperative recovery was eventful with the patient experiencing severe back pain radiating down the leg accompanied with fever. CT showed persistent, right iliopsoas haematoma and pelvic haematoma with secondary hydronephrosis. Viral screen for hepatitis B, C and HIV returned positive. The patient was started on intravenous meropenem. Fever and pain settled. Repeated CT scan showed decrease in retroperitoneal pelvic haematoma.

Introduction Meningitis is one of the leading causes of death among patients living with HIV in sub-Saharan Africa. There is no widespread tracking of the incidence rates of causative agents among patients living with HIV, yet the aetiologies of meningitis are different than those of the general population. Methods We reviewed the scientific literature published in PubMed to determine the incidence rates of meningitis among hospitalized people living with HIV in sub-Saharan Africa and report our findings from seven studies across sub-Saharan Africa. Results We found high rates of cryptococcal meningitis (19–68%). Tuberculous meningitis was lower (1–36%), although some centres included possible cases as “other” meningitis; therefore, this may not be a true representation of the total cases. Pyogenic meningitis ranged from 6 to 30% and “other” meningitis ranged from 7 to 28% of all reported cases of meningitis. Mortality rates ranged from 25 to 68%. This review describes the most common aetiologies and provides practical diagnostic, treatment and prevention considerations as they apply to the individual living with HIV in sub-Saharan Africa. Conclusions Diagnosis is often limited, and wider availability of accurate and low-cost laboratory diagnostics is desperately needed for prompt diagnosis and initiation of appropriate treatment. Wider acceptance and adoption of available preventative modalities can decrease the incidence of potentially fatal central nervous system infections in African patients living with HIV. PMID:25308903

Graves' disease (GD) as an immune reconstitution inflammatory syndrome during highly active antiretroviral therapy (HAART) for HIV has previously been reported. However, clinical challenges associated with HIV in the context of thyroid eye disease (TED) are not as well-characterized. To determine the frequency of coexisting HIV and TED, describe TED presentation and course in the context of HIV, and evaluate management difficulties as well as potential solutions. Cross-sectional study of all patients with coexisting GD and HIV at University Hospitals Birmingham (2003-2014). Retrospective case note review to identify TED with particular reference to HAART regimen, CD4+ T-cell count, HIV viral load, and TED activity and severity. Of 783 subjects with GD and 1186 with HIV, 11 were identified with both GD and HIV. Of these, three had clinical features of TED; each was of Afro-Caribbean origin, was in their fourth decade, and initially presented with undetectable CD4 T cells and high HIV viral loads. All went on to develop GD >3 years after commencing HAART, with normal CD4 count and undetectable viral load at the time of GD diagnosis. The full spectrum of TED was represented, with two subjects requiring orbital decompression surgery. TED in the context of HIV is uncommon. Many challenges exist in such patients, particularly HAART drug interactions with antithyroid and immunosuppressant medications. To better understand TED in HIV and to counsel patients with this copathology most effectively, future multicenter surveillance is required.
Facial lipoatrophy is characterized by fat loss and redistribution. It is a natural, biological phenomenon that occurs over time, presenting as mild-to-moderate volume depletion that gives the skin the appearance of sagging. More recently, highly active antiretroviral therapy, introduced for the management of human immunodeficiency virus, has been associated with moderate-to-severe facial lipoatrophy, and is characterized by sunken cheeks, accentuated nasolabial folds, and protruding musculature and bones. Furthermore, the consequences of facial lipoatrophy have been found to substantially impact patient quality of life. Nurses play an integral role in the treatment of facial lipoatrophy by educating the patients on available therapies and assisting them in making informed treatment decisions. It is important that treating nurses conduct a well-organized interview to understand patient treatment goals. This article will discuss several treatment options available to correct facial lipoatrophy-associated volume deficits, including collagen, hyaluronic acid, calcium hydroxylapatite, poly-L-lactic acid, and permanent implants and injectables.

Kaposi sarcoma is a highly vascularised tumour affecting the skin, lymph nodes and viscera. Kaposi sarcoma is most common in HIV-infected homosexual or bisexual men. We present here a 70-year-old white British male patient, who was under the care of the podiatric team for longstanding 'diabetic foot ulcers'. He was later referred to the Dermatology team who took a biopsy; this revealed features of Kaposi sarcoma which prompted an HIV test which was positive. This patient had previously presented to several healthcare professionals with symptoms suggestive of HIV infection. He was started on antiretroviral therapy and the HIV and human herpesvirus-8 viral loads became undetectable in the blood within weeks and he showed significant clinical improvement. This case report is a reminder to clinicians to have a high index of suspicion in patients presenting with symptoms and signs suggestive of HIV infection. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

To describe tuberculosis (TB) incidence, risk factors, clinical presentation, disease management and outcomes in human immunodeficiency virus (HIV) infected patients from the CoRIS cohort, Spain, 2004-2010. Open multicentre cohort of antiretroviral treatment (ART) naïve patients at entry. Incidence and risk factors were evaluated using multivariate Poisson regression. Among 6811 patients, 271 were eligible for the study and 198 for the estimation of the incidence rate; TB incidence ranged from 12.1 to 14.1/1000 person-years. TB was associated with low education level (rate ratio [RR] 2.65, 95%CI 1.73-4.07), being sub-Saharan African (RR 3.14, 95%CI 1.81-5.45), heterosexual (RR 2.01, 95%CI 1.22-3.29) or an injecting drug user (RR 2.11, 95%CI 1.20-3.69), not undergoing ART (RR 3.33, 95%CI 2.22-4.76), CD4 <200 cells/mm(3) (RR 5.20, 95%CI 3.25-8.33) and log-viral load of 4-5 (RR 5.44, 95%CI 3.28-9.02) or >5 (RR 13.10, 95%CI 8.27-20.76). Overall, 87% were new cases and 13% were previously treated cases; 175 (65%) were bacteriologically confirmed. Drug susceptibility testing was performed in 146 (83%) patients: resistance to first-line drugs was 11.1% in new and 36.4% in previously treated cases. Standard anti-tuberculosis treatment with four or three drugs was prescribed in respectively 55% and 36% of cases. Treatment default was 11%, and was higher among previously treated cases; 80% received ART during anti-tuberculosis treatment, 80% of new and 50% of previously treated cases were cured or completed treatment, and 18 (6.6%) died. TB incidence in HIV-infected patients remains high. Interventions should include early HIV diagnosis and access to ART, enhanced bacteriological confirmation, wider use of four-drug regimens and reduction in treatment default.

A 45-year-old previously healthy man presented with minimally itchy spiny papular lesions of 3 years' duration and discharging nodular cystic lesions for the past 2 years. Initially, lesions appeared on his ears, followed by the gradual appearance of similar lesions over his face, back, and extremities. The lesions were not associated with photosensitivity. Over the years, the patient continued to have similar lesions without any significant response to various topical medications and oral antibiotics. There was no history of fever or any other systemic complaints and the patient denied any other significant medical problems in the past. Cutaneous examination revealed multiple, grouped, spiny papular lesions coalescing to form plaques at places over the ears, extremities, and trunk (Figure 1). Elongated, horny, follicular spires were noted on the top of the papular lesions. Multiple discharging nodular lesions with crusting were seen predominantly over the chest, abdomen, and back (Figure 2), and closed comedonal lesions were noted on the face and trunk. Multiple orange-brown scaly plaques were seen over the extensor aspect of the patient's thighs (Figure 1, inset). A few nails showed wedge-shaped thickening without subungual hyperkeratosis or other nail changes. Palms, soles, and oral mucosa were normal. Considering the atypical cutaneous findings, the clinical possibility of pityriasis rubra pilaris (human immunodeficiency virus [HIV]-associated type 6 PRP) was considered. Hematoxylin and eosin stain of skin biopsy specimens taken from the spiny papular and plaque lesions revealed marked hyperkeratosis with alternating orthokeratosis and parakeratosis with follicular keratotic plugging (Figure 3; Figure 3, inset). Irregular broad acanthosis was also detected in the epidermis. Dermis showed moderate perivascular lymphomononuclear inflammatory infiltrate. Thus, the skin biopsy was consistent with PRP.

Objectives The extent in which clinical progression of HIV-positive patients leads to an increase in healthcare utilization, especially prior to their death, is unknown. Thus, we modeled trends in CD4 cell count and emergency department utilization and the likelihood of an emergency department visit leading to a transfer to acute care level facility prior to a patient’s death from non-accidental causes. Methods Eligible patients initiated HAART in British Columbia between August 1996 and June 2006 (N=457). Patients were followed until their death, which occurred on or before June 30, 2007 (period in which the emergency department visit data were available). Trends were modeled using generalized mixed effects. Results Patients experienced a significantly steep decline in CD4 cell count and a corresponding increase in the number of emergency department visits and transfers to acute level facilities in the five years prior to death. For every 6-month interval prior to death, the CD4 cell count decreased 13.22 cells/mm3, the risk of experiencing an emergency department visit increased by 9%, and among those ever admitted, the odds ratio of being transferred to an acute care level facility increased by 3%. Conclusions We showed that patients experienced a steep decline in CD4 cell count, which was associated with an increase in healthcare utilization prior to their death. These findings highlight the substantial residual avoidable burden that unsuccessfully managed HIV disease poses, even in the HAART era. Further strategies to enhance sustained and successful engagement in care are urgently needed to mitigate high healthcare utilization. PMID:24641495

To report a case of endogenous endophthalmitis caused by the gram-negative bacterium Salmonella choleraesuis as a first sign of HIV infection in a patient from Thailand. Case description and literature review. A 54-year-old male without systemic complaints developed non-painful panuveitis in his left eye accompanied by high intraocular pressure. On investigation, HIV serology was found positive, and aqueous and blood cultures revealed the bacterium Salmonella choleraesuis. Despite aggressive treatment with antibiotics, the affected eye did not improve, and his visual acuity decreased to no light perception. Endogenous endophthalmitis with the non-typhoidal Salmonellae can occur in the absence of systemic symptoms in an immunocompromised host.

ABSTRACT Cryptococcosis is a major invasive fungal disease related worldwide with the AIDS population. New reports of HIV/AIDS cases to the national public health surveillance system (SIVIGILA) in Colombia have shown that there is a growing community at risk of contracting cryptococcosis throughout the country who do not have access to ART. Even though the most prevalent species Cryptococcus neoformans is mainly associated with the HIV population, we report a fatal case of cryptococcosis in an AIDS patient in Barranquilla, associated with Cryptococcus gattii VGI, isolated from blood culture.

Background: Deficiency of micronutrients is prevalent even before the development of symptoms of HIV disease and is associated with accelerated HIV disease progression. Aims: This study evaluates the prevalence of folate and Vitamin B12 deficiency in HIV-positive patients with or without tuberculosis (TB) and its association with neuropsychiatric symptoms and immunological response. Settings and Design: Cross-sectional, observational study in an outpatient setting. Patients and Methods: Four groups of HIV-positive patients with TB (Group I), HIV-positive patients with neuropsychiatric symptoms (Group II), HIV-positive patients without neuropsychiatric symptoms or TB (Group III), and HIV-negative controls with neuropsychiatric symptoms (Group IV). Vitamin B12 and folate estimation was done using carbonyl metallo-immunoassay method. Statistical Analysis Used: ANOVA, Kruskal–Wallis and Mann–Whitney, Pearson's correlation. Results: The prevalence of folic acid deficiency was 27.1% in the Group I, 31.9% in the Group II, 23.4% in the Group III, and 32% in the Group IV being higher in patients with neuropsychiatric symptoms in both HIV and non-HIV patients. The prevalence of Vitamin B12 deficiency was 18.8% in Group I, 9.1% in Group II, 4.8% in Group III, and 16.7% in Group IV. The patients with folate deficiency had more severe depression and anxiety. Conclusion: Nearly, 30% of the HIV patients had a folic acid deficiency, and about 10% of the HIV patients had Vitamin B12 deficiency. The folate deficiency was highest among neuropsychiatric patients with or without HIV infection and Vitamin B12 deficiency was higher among HIV patients with TB. PMID:27890954

Objective: To determine the utility of gingival crevicular fluid (GCF) for the detection of anti-HIV antibodies in human immunodeficiency virus (HIV)-infected individuals using enzyme linked immunosorbent assay (ELISA) with respect to their CD4 counts. Materials and Methods: The study was carried out between 37 seropositive (37GCF, 10 saliva) and 37 seronegative (GCF) individuals for a period of 7-8 months in GDC Nagpur. Thirty-seven GCF and 10 whole saliva samples were collected from the same patient. GCF samples were collected from gingival crevice with the help of Kimble disposable microcapillary. Saliva was collected by asking the patient to bend forward. The drooling saliva was collected in a sterile bottle and stored at Minus 20°C (-20°C). After the clinical observations the data were collected and tabulated for statistical analysis. Results: When compared with serum, the sensitivity, specificity, and positive and negative predictive values of GCF were 100% respectively. Conclusion: All the above findings are suggestive of GCF being a better diagnostic medium than saliva. PMID:25767763

Research is lacking on factors associated with antiretroviral therapy (ART) sub-optimal adherence among U.S. Latinos, who are disproportionately affected by HIV and face substantial health care barriers. We examined self-reported, patient-initiated changes to ART (i.e., made small/major changes from the antiretroviral drugs prescribed) among HIV-positive Latinos. Trained interviewers administered surveys to 230 participants currently on ART in San Diego, U.S. and Tijuana, Mexico. We identified factors independently associated with ART changes. Participants were Spanish-language dominant (86%), mean age of 41 years, male (77%), and born in Mexico (93%). Patient-initiated changes to ART were reported in 43% of participants. Being female, having ≥1 sexual partner (past 3 months), ≥6 years since HIV diagnosis and poor health were associated with increased odds of ART changes. Findings raise concern about sub-optimal adherence among this binational population. Longitudinal studies are needed to further explore adherence barriers and avenues for intervention. PMID:21800182

Human immunodeficiency virus (HIV) infection disturbs the host's immune function and often coexists with various autoimmune and/or systemic rheumatic diseases with manifestations that sometimes overlap with each other. We herein present the case of a 43-year-old Japanese man infected with HIV who exhibited elevated serum creatine kinase and transaminases levels without any symptoms. He was diagnosed with autoimmune hepatitis, polymyositis and Sjögren's syndrome and received combined antiretroviral therapy (cART); however, the laboratory abnormalities persisted. We successfully administered cART with the addition of oral prednisolone, and the patient's condition recovered without side effects related to the metabolic or immunosuppressive effects of these drugs.

Background We examined the effect of hepatitis C virus (HCV) seropositivity on risk of death among people receiving their first antiretroviral treatment (ART) for HIV infection. Methods In British Columbia, the HIV/ AIDS Drug Treatment Program is the only source of free ART. Patients who initiated a triple-drug ART regimen between July 31, 1996, and July 31, 2000, were included if they were ART-naive and had baseline HCV serological data. Outcomes of interest for survival analysis were deaths from natural and HIV-related causes, with a data cutoff of June 30, 2003. Results Of 1186 eligible subjects, 606 (51%) were HCV positive and 580, negative. Fewer HCV-positive people were male (78% v. 93%, p < 0.001) and had an AIDS diagnosis at baseline (11% v. 15%, p = 0.028). Their CD4 fraction was significantly higher at baseline (19% v. 16% of T lymphocytes, p < 0.001) but their absolute CD4 counts, log HIV viral load and the type of ART initiated were similar to those of HCV negative people. Of 163 deaths (from natural causes only) during the study period, 118 (19%) were in HCV positive and 45 (8%) in HCV negative patients (p < 0.001); of the 114 deaths attributed to HIV infection, these proportions were 79 (13%) versus 35 (6%; p < 0.001). After adjustment for potential confounders, HCV seropositivity remained predictive of death (adjusted hazard ratio [HR] 2.20, 95% confidence interval [CI] 1.50– 3.21, p < 0.001), especially HIV-related death (adjusted HR 1.75, 95% CI 1.13– 2.72, p = 0.012). Interpretation In this population-based HIV treatment program, we found HCV seropositivity to be an independent predictor of mortality, especially death related to HIV infection. PMID:16027432

Deficiency of micronutrients is prevalent even before the development of symptoms of HIV disease and is associated with accelerated HIV disease progression. This study evaluates the prevalence of folate and Vitamin B12 deficiency in HIV-positive patients with or without tuberculosis (TB) and its association with neuropsychiatric symptoms and immunological response. Cross-sectional, observational study in an outpatient setting. Four groups of HIV-positive patients with TB (Group I), HIV-positive patients with neuropsychiatric symptoms (Group II), HIV-positive patients without neuropsychiatric symptoms or TB (Group III), and HIV-negative controls with neuropsychiatric symptoms (Group IV). Vitamin B12 and folate estimation was done using carbonyl metallo-immunoassay method. ANOVA, Kruskal-Wallis and Mann-Whitney, Pearson's correlation. The prevalence of folic acid deficiency was 27.1% in the Group I, 31.9% in the Group II, 23.4% in the Group III, and 32% in the Group IV being higher in patients with neuropsychiatric symptoms in both HIV and non-HIV patients. The prevalence of Vitamin B12 deficiency was 18.8% in Group I, 9.1% in Group II, 4.8% in Group III, and 16.7% in Group IV. The patients with folate deficiency had more severe depression and anxiety. Nearly, 30% of the HIV patients had a folic acid deficiency, and about 10% of the HIV patients had Vitamin B12 deficiency. The folate deficiency was highest among neuropsychiatric patients with or without HIV infection and Vitamin B12 deficiency was higher among HIV patients with TB.

The role of allogeneic hematopoietic cell transplantation (alloHCT) in HIV-positive patients is not known. Using the CIBMTR database, we retrospectively evaluated 23 HIV-positive patients undergoing matched sibling (n=19) or unrelated (n=4) donor transplants between 1987 and 2003. The median age at alloHCT was 32 years. Indications for alloHCT were diverse and included malignant (n=21) and non-malignant (n=2) hematologic disorders. Nine patients (39%) were transplanted after 1996, the approximate year highly active anti-retroviral therapy became standard. The median time to neutrophil engraftment was 16 days (range 7–30) and the cumulative incidences of grades II – IV acute graft-versus-host disease (GVHD) at 100 days, chronic GVHD and survival at 2 years were 30% (95% C.I. 14-50), 28% (95% C.I. 12-48) and 30% (95% C.I. 14-50), respectively. At a median follow-up of 59 months, 6 patients are alive. Survival appears better among the patients transplanted after 1996: 4 of 9 patients transplanted after 1996 survive compared to 2 of 14 patients transplanted prior to 1996. These data suggest that alloHCT is feasible for selected HIV-positive patients with malignant and non-malignant disorders. Prospective studies are needed in these patients to evaluate the safety and efficacy of this modality in specific diseases. PMID:19539219

Employment-based reinforcement interventions have been used to promote abstinence from drugs among chronically unemployed injection drug users. The current study used an employment-based reinforcement intervention to promote opioid and cocaine abstinence among opioid and/or cocaine-dependent, HIV-positive participants who had recently completed a brief inpatient detoxification. Participants (n = 46) were randomly assigned to an abstinence and work group that was required to provide negative urine samples in order to enter the workplace and to earn incentives for work (n = 16), a work-only group that was permitted to enter the workplace and to earn incentives independent of drug use (n = 15), and a no-voucher control group that did not receive any incentives for working (n = 15) over a 26-week period. The primary outcome was urinalysis-confirmed opioid, cocaine, and combined opioid/cocaine abstinence. Participants were 78% male and 89% African American. Results showed no significant between-groups differences in urinalysis-verified drug abstinence or HIV risk behaviors during the 6-month intervention. The work-only group had significantly greater workplace attendance, and worked more minutes per day when compared to the no-voucher group. Several features of the study design, including the lack of an induction period, setting the threshold for entering the workplace too high by requiring immediate abstinence from several drugs, and increasing the risk of relapse by providing a brief detoxification that was not supported by any continued pharmacological intervention, likely prevented the workplace from becoming established as a reinforcer that could be used to promote drug abstinence. However, increases in workplace attendance have important implications for adult training programs.

With up to 40% of opioid injectors infected with HIV, Ukraine has one of the most concentrated HIV epidemics in the world, mainly due to unsterile injection practices and a historical absence of effective prevention services. Harm reduction programs, including syringe exchange and a small buprenorphine treatment program, were introduced in 2004 and methadone maintenance was allowed in 2007. Despite an initial expansion, by 2009, only 3221 injectors were receiving methadone treatment. A growing body of research on methadone maintenance has found high retention rates with reduction in opioid use and HIV risk behaviors. We report on the acceptability and initial outcome of methadone treatment as a function of HIV status, an issue that has not yet been reported for injectors in Ukraine. Longitudinal observational study of a 12-week course of methadone treatment in 25 HIV+ and 25 HIV- opioid addicted individuals recruited from a harm reduction program and the city AIDS Center. Drug use and HIV risk were assessed at baseline and weeks 4, 8, 12 and 20; all patients were offered continued methadone maintenance in the Kyiv city program at the end of 12 weeks. Fifty-four individuals were asked if they were interested in the study and 50, demographically similar to other samples of opioid addicted Ukrainians, agreed to participate. Two died of non-study related causes; the other 48 completed assessments at weeks 4, 8 and 12, and 47 completed followups at week 20. Significant reductions were seen in use of heroin (p<0.0001), other opiates/analgesics (p<0.0001), and HIV risk behaviors (drug, sex, total; all p<0.0001). All 48 patients chose to continue methadone after the 12-weeks of study medication ended. Unlike most opioid treatment studies, sexual risk was somewhat higher than injecting risk at study intake. Methadone maintenance was well accepted by HIV+ and HIV- opioid dependent individuals and has the potential for significant public health impact if made more widely

The clinical trial aimed to evaluate the survival of implant-prosthetic rehabilitation in controlled HIV-positive patients. This mono-centric study included HIV patients with a stable disease, requiring implant rehabilitation, with good oral hygiene. Each patient received at least one dental implant. After 90 days in the upper jaw and 60 days in the lower jaw, the appropriate prosthesis was delivered.Primary outcome measures were prosthetic failures, implant failures, peri-implant marginal bone level changes (MBLCs), and biological complications (peri-implantitis, pus, pain, paresthesia). Data were recorded before the intervention (T0), and 6 (T1) and 12 months (T2) after. Implants were positioned in 68 patients (22 females and 46 males; 194 implants). Two dropouts occurred for exacerbation of the disease before the sixth month of follow-up, and 66 patients (with 190 implants) completed the study. Forty-eight patients (70.6%) received total removable dentures; 11 patients (16.2%) received partial prosthesis, and nine patients (13.2%) received single elements.Implant failure occurred in nine patients (15 fixtures out of 190). These were early implant failures due to primary infection (five fixtures out of 190: 2.6%) and to peri-implantitis (10 fixtures out of 190: 5.2%). Prosthetic failure was registered in two patients (3% of patients) due to the loss of all the fixtures. Pus and pain were observed in 4/7 and 3/7 patients with peri-implantitis, respectively. No fractures of fixtures or paresthesia were registered. At T2, the mean peri-implant MBLC was -1.19 ± 0.87 mm. Within its limitations, the study showed that in a well-controlled population of HIV patients implant rehabilitation can be a suitable options with results slightly worse to those obtained in normal population. A higher incidence of peri implant infections in the first six months was present pointing to the need of a proper protocol for infection control. © 2015 Wiley Periodicals, Inc.

There has been several reports of an MND like syndrome in HIV-1 infection, however the data is still sparse. Furthermore, HIV-associated amyotrophic lateral sclerosis (ALS) syndrome differs from the classical ALS in some key aspects.. A 44-year-old male presented with a history of insidious onset and gradually progressive asymmetric weakness of lower limbs. He also complained of thinning in both legs, the left leg more than the right since 1 year along with spontaneous twitching of muscles in both the thighs. On neurological examination, the assessment of higher mental functions was normal. There were no cranial nerve deficits. Motor power was grade 5/5 (Medical Research Council scale) in both the upper limbs and 4+ at hips and knees bilaterally, 5 at right ankle, and 4+ at left ankle. All the deep tendon reflexes were brisk with extensor planter responses. There were no cerebellar signs or sensory deficits. HIV-1 was reactive in enzyme-linked immunosorbent assay. Electrophysiological studies were conducted per the MND protocol.None of the nerves studied showed an abnormal drop in compound muscle action potential amplitude with proximal stimulation. There was evidence of diffuse spontaneous activity, which manifests as fibrillation and fasciculation potentials in most muscles tested . Overall there seems to be sufficient evidence to implicate HIV as a potential cause of an ALS-like disorder, but one must also consider the possibility of coincidental HIV infection in patients who have sporadic ALS.

Renal disease is an important and commonly encountered co-morbidity in HIV infection. Despite this, few data are available concerning renal disease in this patient group. A retrospective review was conducted of all HIV-positive patients of an inner metropolitan sexual health service who attended from 1 August 2013 to 31 July 2014 for HIV management. One hundred eighty-eight HIV-positive patients attended the clinic during the study period. The majority were male (96%), Caucasian (70%) and 30-39 years of age (37%). There was a high prevalence of renal risk factors in the population, including potentially nephrotoxic antiretroviral therapy (61%), smoking (38%), hypertension (12%), dyslipidemia (11%) and hepatitis C co-infection (7%). In the previous year, measurements of estimated glomerular filtration rate were performed in all patients, but measurements of lipid profiles, urinary protein and serum phosphate were performed within the last year in only 48%, 33% and 30% of patients, respectively. These are the first comprehensive data regarding renal disease, associated risk factors and screening and management practices in the HIV-positive patient population of a specialized sexual health service in Australia. This patient population demonstrates a particularly high prevalence of risk factors for renal disease. Despite this, screening investigations were not performed as recommended. This represents a potential area to improve patient care.

Cryptococcal meningoencephalitis has an overall global mortality rate of 20% in AIDS patients despite antifungals. There is a need for additional means of precise assessment of disease severity. We thus studied the radiological brain images available from 62 HIV-positive patients with cryptococcocal meningoencephalitis to analyse the brain lesions associated with cryptococcosis in relationship with disease severity, and the respective diagnostic contribution of magnetic resonance (MR) versus computed tomography (CT). In this retrospective multicenter analysis, two neuroradiologists blindly reviewed the brain imaging. Prospectively acquired clinical and mycological data were available at baseline and during follow-up. Baseline images were abnormal on 92% of the MR scans contrasting with 53% of the CT scans. MR/CT cryptococcosis-related lesions included mass(es) (21%/9%), dilated perivascular spaces (46%/5%) and pseudocysts (8%/4%). The presence compared to absence of cryptococcosis-related lesions was significantly associated with high serum (78% vs. 42%, p = 0.008) and CSF (81% vs. 50%, p = 0.024) antigen titers, independently of neurological abnormalities. MR detected significantly more cryptococcosis-related lesions than CT for 17 patients who had had both investigations (76% vs. 24%, p = 0.005). In conclusion, MR appears more effective than CT for the evaluation of AIDS-associated cerebral cryptococcosis. Furthermore, brain imaging is an effective tool to assess the initial disease severity in this setting. Given this, we suggest that investigation for cryptococcosis-related lesions is merited, even in the absence of neurological abnormality, if a high fungal burden is suspected on the basis of high serum and/or CSF antigen titers.

Human herpesvirus 8 (HHV-8), classified in Herpesviridae family, is the etiological agent of Kaposi's sarcoma (KS), primary effusion lymphoma and multicentric Castleman's disease. In contrast to the other herpesviruses, HHV-8 seroprevalence is low in general populations; however, the higher prevalence observed in individuals with immunodeficiencies such as AIDS poses an increased risk for KS. The global distribution of HHV-8 shows great variations, with the highest seroprevalence seen in Africa. The number of studies on the seroprevalence of HHV-8 in Turkey are limited. The aim of this study was to determine the HHV-8 seroprevalences in healthy blood donors and HIV-positive patients, that will contribute HHV-8 seroepidemiological data in our country. This study was designed as a cross-sectional study. A total of 551 healthy donors (76 female, 475 male; age range: 18-65 years) admitted to Ege University Medical School Hospital, Blood Center for blood donation between December 2013-January 2014, and 173 HIV-positive patients (30 female, 143 male; age range: 18-65 years) admitted to infectious diseases outpatient clinic between October 2013-January 2014, were included in the study. A commercial ELISA method (KSHV/HHV-8 IgG ELISA Kit, Advanced Biotechnologies Inc, USA) was used for the detection of IgG antibodies that were structured against HHV-8 lytic antigens. In the study, 29 (29/551, 5.3%) of blood donors and 44 (44/173, 25.4%) of HIV-positive patients, with a total of 73 (73/724, 10.1%) cases were found as HHV-8 seropositive. The difference between blood donors and HIV-positive patients in terms of HHV-8 seropositivity rates was statistically significant (5.3% versus 25.4%; p< 0.05). In both of the study groups, no statistically significant difference was detected between HHV-8 seropositivity with gender and age. When considering HIV-positive patients, no statistically significant difference was observed between HHV-8 seropositivity with the duration of anti-HIV

Mobile phone technology is increasingly used to overcome traditional barriers limiting access to care. The goal of this study was to evaluate access and willingness to use smart and mobile phone technology for promoting adherence among people attending an urban HIV clinic. One hundred consecutive HIV-positive patients attending an urban HIV outpatient clinic were surveyed. The questionnaire evaluated access to and utilization of mobile phones and willingness to use them to enhance adherence to HIV medication. The survey also included the CASE adherence index as a measure of adherence. The average age was 46.4 (SD = 9.2). The majority of participants were males (63%), black (93%), and Hispanic (11.4%) and reported earning less than $10,000 per year (67.3%). Most identified themselves as being current smokers (57%). The vast majority reported currently taking HAART (83.5%). Approximately half of the participants reported some difficulty with adherence (CASE < 10). Ninety-six percent reported owning a mobile phone. Among owners of mobile phones 47.4% reported currently owning more than one device. Over a quarter reported owning a smartphone. About 60% used their phones for texting and 1/3 used their phone to search the Internet. Nearly 70% reported that they would use a mobile device to help with HIV adherence. Those who reported being very likely or likely to use a mobile device to improve adherence were significantly more likely to use their phone daily (P = 0.03) and use their phone for text messages (P = 0.002). The vast majority of patients in an urban HIV clinic own mobile phones and would use them to enhance adherence interventions to HIV medication.

This retrospective cohort study examined electronic medical records of HIV-positive patients in California (N=7,834) to find the prevalence of any psychiatric condition and the associations between several factors and the likelihood of these disorders. Approximately 53% of the patients in this study had a documented psychiatric condition, including 23% who had a mood disorder, 19% who had a substance-related disorder, and 16% who had an anxiety disorder. After controlling for potential confounders, significant positive associations (p<0.001) were found between female gender and the presence of any mood disorder (Adjusted Odds Ratio [95% Confidence Interval]=1.58[1.26–1.99]) or anxiety disorder (AOR=1.54[1.18–2.02]) and between homosexual orientation and the presence of any psychiatric condition (AOR=1.33[1.15–1.55]), mood disorder (AOR=1.71[1.42–2.07]), or anxiety disorder (AOR=1.41[1.22–1.88]). There were also significant negative associations between African American race and the presence of any psychiatric condition (AOR=0.68[0.60–0.77]), mood disorder (AOR=0.74[0.64–0.86]), anxiety disorder (AOR=0.43[0.36–0.52]), or substance-related disorder (AOR=0.78[0.67–0.91]) and between state/federal insurance and the presence of any psychiatric condition (AOR=0.70[0.62–0.79]), mood disorder (AOR=0.71[0.62–0.80]), or anxiety disorder (AOR=0.77[0.66–0.89]).

Background Sexual behaviours among HIV-positive male patients in Cambodia have not been fully evaluated. Objectives The patterns of sexual behaviours and social factors were compared between married and single men. Methods A retrospective cross-sectional survey of 174 male HIV patients was undertaken during March 1999–June 2000 in Phnom Penh. Results Many participants (61%) reported that they were unaware that their sexual behaviours may have put them at risk of HIV infection. Sexual behaviours included having sex with a sex worker (90%), multiple sexual partners (41%), and both of these behaviours (37%). Two-thirds (69%) reported using a condom when having sex with a sex worker. Condom use with multiple sexual partners was low (24%). A history of condom use with a sex worker was less likely to be reported among married men than single men (P = 0.008). Always using condoms with a sex worker did not differ between married men and single men. Social factors that influenced visiting a sex worker included invitation by a friend (88%), alcohol consumption (74%), and having extra spending money (72%). Multivariate analysis suggests that alcohol consumption (P = 0.008) and having extra spending money (P = 0.02) were strongly associated with visiting a sex worker. Conclusions In Cambodia, HIV-infected men frequently reported a history of using sex workers. Having multiple sex partners or using a sex worker and multiple sexual partners were not rare. Interventions should target men in settings where alcohol is consumed and to encourage married men to use condoms. PMID:19061555

To assess cancer incidence and all-cause mortality trends in HIV-positive patients in Algeria before and during the highly active antiretroviral therapy (HAART) era. Cross-sectional study. We used hospital-based data of patients with HIV/AIDS between January 1988 and December 2010. Cancer incidence, standardized mortality ratios (SMRs), risk of death, and proportion of HIV-positive patients treated before and during the HAART era were calculated. The joinpoint model was used to assess the magnitude of changes in SMRs. In 1988-2010, 156 patients were diagnosed as HIV-positive. During pre-HAART era, Kaposi sarcoma (KS) incidence was 5%. After the introduction of HAART, KS incidence decreased to 2%. No other AIDS-related cancer was diagnosed during the study. One-third died (52/156), of which 83.6% died in the same year as or in the year after HIV diagnosis; median age at death (interquartile range) was 34.5 (11.8) years. Yearly risk of death declined from 100% in 1998 to 8% in 2010; percentage of patients treated with HAART increased from 13% in 1998 to >80% after 2002. Overall SMR decreased from 200.2 (95% confidence interval [95% CI], 123.2-325.2) before the HAART era to 91.4 (95% CI, 66.0-126.6) thereafter. From 2003, yearly SMRs decreased significantly by 66.1% (P < 0.05) until 2006 but not thereafter. Since 1998, the proportion of HIV-positive patients treated with HAART increased, reaching 84% in 2010, all-cause mortality decreased, and cancer remained rare. However, almost all patients who died during the study seemed to be diagnosed at a late stage of the disease, emphasizing the need for earlier diagnosis of HIV in Algeria.

Introduction Fungal respiratory infections are important cause of mortality and morbidity among HIV positive individuals. They account for up to 70% of illness in Acquired Immunodeficiency Disease Syndrome cases (AIDS). The range of illness varies from asymptomatic mucosal candidiasis to overwhelming disseminated infections. In these patients dissemination of fungus leads to very serious outcomes hence, it is important to have the knowledge of prevailing profile of fungus causing infections, so that it can be treated at the onset. Low CD4+ T lymphocyte count is an excellent indicator of decreased immunity and can also be helpful to predict opportunistic fungal respiratory infections and other complications. Aim To define the fungal aetiology of lower respiratory tract infections in HIV positive patients and to correlate the occurrence of different fungi with CD4+ T lymphocyte count. Materials and Methods This was a cross sectional study conducted between May 2014 to April 2015, on 180 treatment naive HIV seropositive patients with lower respiratory tract infections attending the Integrated Counselling and Testing Centre, SMS Medical College, Jaipur, Rajasthan. Early morning expectorated and induced sputum samples were collected and processed for isolation and identification of fungal species. CD4+ T lymphocyte count estimation was done by BD FACS Calibur. Results Fungal species were isolated from 155 (86.1%) patients. The most common isolate was Candida albicans (31.7%), followed by Aspergillus niger (17.7%) and Aspergillus flavus (10%). The fungal species were most commonly isolated from patients with CD4+ T lymphocyte cell less than 200 cells/μl. Conclusion Fungal infections were seen in 86.1% of HIV positive patients with lower respiratory tract infections hence, high level of clinical suspicion for fungal aetiology of respiratory infections in HIV positive patients should be kept in mind.

Background Ocular lesions in patients on highly active antiretroviral therapy (HAART) have shown changes in disease prevalence and pattern. Although they have been described in the Western population, there are not many such studies in the HAART era from India. This study aims to present the clinical profile, systemic correlation, and visual outcome in HIV-positive patients in relation to HAART in comparison with pre-HAART Indian studies and current Western data. Ocular findings and systemic correlation in 1,000 consecutive patients with HIV seen at a tertiary eye care center were analyzed. This study uses a prospective observational case series design. Results Age range of the patients was 1.5 to 75 years. Ocular lesions were seen in 68.5% of the patients (cytomegalovirus (CMV) retinitis was the commonest). The commonest systemic disease was pulmonary TB. Mean interval between HIV diagnosis and onset of ocular lesions was 2.43 years. CD4 counts range from 2 to 1,110 cells/mm3. Immune recovery uveitis (IRU) was seen in 17.4%. Interval between HAART initiation and IRU was 4 months to 2.5 years. Recurrence of ocular infection was seen in 2.53% (post-HAART) and > 20% (pre-HAART). Overall visual outcome showed improvement in about 14.3% and was maintained in 71.6% of the patients. Conclusions CMV retinitis is the commonest ocular opportunistic infection in India, even in the HAART era. Newer manifestations of known diseases and newer ocular lesions are being seen. In contrast to Western studies, in our patients on HAART, ocular lesions do not always behave as in immunocompetent individuals. Ocular TB needs to be kept in mind in India, as well as other neuro-ophthalmic manifestations related to cryptococci, especially in gravely ill patients. Occurrence and frequency of various ocular opportunistic infections in developing nations such as India have significant variations from those reported in Western literature and need to be managed accordingly.

The present study examined the impact of cognitive reserve in maintaining intact neuropsychological (NP) function among older HIV-positive individuals, a uniquely at-risk subgroup. Participants included 129 individuals classified by HIV serostatus, age group, and NP impairment. A three-way analysis of variance (ANOVA) followed by a series of within-group ANOVA and multiple regression analyses were conducted to investigate the pattern of cognitive reserve (vs. other protective) influence among groups with varying risks of NP impairment. Results indicated a significant age ×HIV status interaction, with older HIV-positive individuals demonstrating higher cognitive reserve than subgroups with less risk for NP compromise (younger age and/or HIV-negative). Results demonstrated higher cognitive reserve specific to NP-intact older HIV-positive individuals. Within this group, the interaction of younger age and higher cognitive reserve independently contributed to cognitive status when controlling for psychiatric, immunological, and psychosocial protective mechanisms, suggesting the importance of cognitive reserve beyond other protective mechanisms in maintaining optimal NP functioning in those individuals most at risk. Alongside younger age, factors contributing to cognitive reserve (i.e., education and estimated premorbid intelligence) may provide substantial benefit for older HIV-positive adults who are at high risk for NP compromise.

Thiazolidinediones (TZD) may improve insulin resistance in patients with diabetes and HIV. The novel adipocytokines visfatin and retinol-binding protein-4 (RBP-4) have been proposed to influence the development of impaired glucose tolerance. The impact of TZD on these cytokines is yet unknown. In this randomized, double-blind, placebo-controlled parallel group study, 37 lean HIV-positive subjects aged 19-50 years were treated with 8 mg/day rosiglitazone (n=20) or placebo (n=17) for 6 months. Insulin sensitivity was estimated from the homeostasis model assessment (HOMA) index. Fasting visfatin, RBP-4, leptin, and adiponectin plasma concentrations were analyzed by immunoassays. Rosiglitazone had no effect on impaired insulin sensitivity, but increased median plasma visfatin from 6.2 ng/ml (95% CI: 5.9; 6.5) to 13.7 ng/ml (12.6; 19.1) (P<0.001) and adiponectin from 3.2 ng/ml (2.2; 4.0) to 4.0 ng/ml (3.3; 8.5; P<0.001). RBP-4 was lowered from 21.0 ng/ml (19.6; 23.1) to 16.3 ng/ml (15.2; 17.0; P<0.001), and leptin concentrations were unchanged. Adipocytokine concentrations were stable in subjects receiving placebo, where a deterioration in insulin sensitivity was detectable (P<0.05). Changes in visfatin and RBP-4 were correlated in subjects receiving rosiglitazone (r=-0.64, P<0.01) but not placebo (r=0.12, P=0.15). TZD treatment affects circulating adipocytokine concentrations in subjects with HIV. Reductions in RBP-4 and increases in visfatin may contribute to the pharmacodynamic action of TZD on glucose homeostasis. Quantification of adipocytokines might be useful to assess TZD treatment effectiveness in insulin-resistant subjects with HIV.

Kidney disease has become an important co-morbidity among human immunodeficiency virus-infected patients as they live longer in the era of highly effective antiretroviral therapy. It remains unclear how co-infection with hepatitis C virus impacts on the trajectory of kidney disease among HIV-infected patients. To evaluate the effect of co-infection with HCV on the risk of kidney disease in HIV-infected populations. We conducted a systematic review of the published medical literature to determine if hepatitis C co-infection is associated with increased likelihood of chronic kidney disease in HIV-positive adults. We used the random effects model of DerSimonian and Laird to generate a summary estimate of the relative risk for chronic kidney disease (defined by reduced glomerular filtration rate and/or detectable proteinuria) with hepatitis C virus across the published studies. Meta-regression and stratified analysis were also conducted. We identified 19 studies (146,151 unique patients with HIV) and separate meta-analyses were performed according to the outcome. Aggregation of longitudinal studies (n = 8, 105,462 unique patients) showed a relationship between HCV infection and increased risk of reduced glomerular filtration rate among HIV-infected individuals, the summary estimate for adjusted hazard ratio was 1.64 (95%CI, 1.28; 2.0, P < 0.001) in HIV-HCV co-infected individuals compared with those having HIV mono-infection. No between-studies heterogeneity was noted (P-value by Q test = 0.08). HCV positive serology was an independent risk factor for proteinuria; adjusted effect estimate, 1.23 (95% confidence interval, 1.18; 1.28, P = 0.001) (n = 6 studies; 26,835 unique patients). In meta-regression, we noted the impact of ageing (P = 0.0001) upon the adjusted hazard ratio of incidence of reduced glomerular filtration rate among HCV-HIV co-infected patients; a negative association between frequency of males (P = 0.001) and the adjusted

The aim of this study was to determine whether highly active antiretroviral therapy (HAART) is associated with the prevalence of oral lesions in HIV-positive patients. This systematic review and meta-analysis was performed in accordance with the PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). The search was conducted in seven electronic databases (PubMed, Scopus, SciELO, LILACS, Embase, Web of Science, and OpenGrey), without restriction on publication period or language. Studies that showed the prevalence of oral lesions manifested in adult HIV-positive patients, subjected or not to HAART, were selected. The meta-analysis estimate of relative risk was calculated using the Mantel-Haenszel method and DerSimonian and Laird estimator to determine the variance between studies in the random-effects model. The meta-analysis showed significant results in favour of the group on HAART, with lower prevalence for angular cheilitis, erythematous candidiasis, oral herpes, pseudomembranous candidiasis, Kaposi sarcoma, and oral hairy leukoplakia. The prevalence of oral mucosal hyperpigmentation was higher in patients on HAART. These results suggest that the prevalence of oral lesions in HIV-positive patients is lower for those on HAART, which might occur because of the improvement in immunity provided by the therapy.

Clostridium difficile is the most important cause of nosocomial diarrhea, mainly associated with antibiotic use and immunodeficiency. Although, an increased incidence of community-acquired C. difficile infection (CA-CDI) has been reported worldwide, this infection has been under-diagnosed in Latin America. This is the first report of a CA-CDI case in Latin America, in an HIV-positive patient with cancer.

Objective To identify determinants of TB case fatality including the impact of antiretroviral therapy (ART) at different CD4 thresholds for HIV-positive adult and adolescent TB patients. Methods Through a retrospective analysis of the electronic TB database, we identified the HIV status of newly registered patients ≥15 yrs. Multivariable Cox proportional hazard models were used to determine risk factors for TB case fatality in these patients. Results In 2009, 2010 and 2011, 25,841, 26,104 and 25,554 newly registered adult TB patients were treated in primary health care clinics in Cape Town, of whom 49.7%, 50.4% and 50.9% were HIV-positive. ART uptake increased over the three years from 43% to 64.9% and case fatality of the HIV-positive patients decreased from 7.0% to 5.8% (p<0.001). Female gender, increasing age, retreatment TB, low CD4 counts and extrapulmonary TB (EPTB) were associated with increased case fatality while patients on ART had a substantial decrease in case fatality. The difference in case fatality between patients on ART and not on ART was most pronounced at low CD4 counts with the positive influence of ART noted up to a CD4 count threshold of 350 cells/mm3 (p<0.001). Despite improvements in ART uptake, in 2011, 21% of patients with CD4 counts <350 cells/mm3 did not start ART during TB treatment. Conclusion This study showed a relatively poor uptake of ART among severely immune-compromised TB patients. Patients with CD4 counts <350 cells/mm3 were shown to clearly benefit from ART during TB treatment and ART initiation should be prioritised for this category of patients. PMID:24820105

The purpose of this study was to investigate the influence of immune deficiency status of HIV-positive patients on postoperative complication such as surgical site infection and nonunions. Retrospective observational cohort study: Level III. Level I trauma center. Consecutive adult HIV-positive patients with closed fractures who underwent operative treatment between January 1, 2001 and December 31, 2012. postoperative complication including infection and fracture nonunion. A total of 42 HIV-positive patients with closed fractures who underwent surgical fracture fixation were identified during the 12-year study time window. Of these, 18 patients were excluded due to incomplete medical records (n = 16) or open fractures (n = 2). The remaining 24 patients with closed fracture treated surgically (19 males and 5 females; mean age 45.1 ± 10.5 years; age range 20-67 years) were included in the study. Within a 6-month period from the time of injury, 16 patients had a CD4+ cell count >200 and five patients had a CD4+ cell count <200 (CD4+ cell count was not available in three patients). Twenty-two patients (91.6 %) were on antiretroviral therapy at the time of injury. Only one patient, with associated end-stage renal failure and diabetes mellitus, developed a postoperative infection (4.2 %). All patients achieved fracture union within 180 days postoperatively, without the need for surgical revisions. Our study suggests that HIV infection does not seem to correlate with a higher risk for the development of postoperative complication related to surgical site infection and fracture nonunions after operative fixation of closed fractures.

A trial of using Short Message Service (SMS) broadcasting at a metropolitan sexual health clinic in 2013 to promote the awareness and uptake of influenza vaccinations in HIV-positive patients resulted in a significant increase in the number of patients contacted (35% vs 81% P<0.0001) and vaccinated by the clinic (26% vs 47% P<0.001) compared with 2012, when individual telephone calls were made to patients. Additional benefits were less staff time used promoting influenza vaccination and the resultant lower staff cost. SMS broadcasting is an efficient and inexpensive method of communicating health messages to large numbers of patients.

Oncogenic human papillomaviruses (HPVs) are associated with oropharyngeal squamous cell carcinoma (SCC). Infection with human immunodeficiency virus (HIV) increases susceptibility to opportunistic infections and viral-promoted cancers. The prevalences of HPV, herpes simplex virus (HSV), Epstein-Barr virus (EBV), and human herpesvirus-8 (HHV-8) have not been established for head and neck squamous cell carcinoma in HIV-positive patients (HIV+ HNSCC). We have observed that HIV+ HNSCC tend to contain numerous multinucleated tumor giant cells, this finding has not been described previously. The goal of this study is to test for these oncogenic viruses in a small cohort of retrospectively identified patients with HIV infection, and to compare histologically these cancers to a control group of HNSCC patients. Tumors were reviewed histologically and compared to a control group of 102 patients with HNSCC (serologically untyped or HIV negative). Polymerase chain reaction (PCR) was performed on formalin-fixed, paraffin-embedded HIV+ HNSCC samples from combined 25 patients in two institutions. In situ hybridization was performed to identify EBV (EBER) and immunohistochemistry was performed to detect HSV-1, HSV-2, HHV-8, and HIV-related proteins (Nef, p24). The study sample consisted of 34 HIV+ patients with HNSCC from Montefiore Medical Center, and six HIV+ HNSCC patients from Hospital Clinic, University of Barcelona; 24 (60%) men and 16 (40%) women. The larynx was most commonly involved (65%, n = 26); followed by the oropharynx (22.5%, n = 9). Four carcinomas arose from the oral cavity (10%) and one from the nasal cavity (2.5%). Histologically, multinucleated tumor giant cells were more common in the HIV+ group (39/40, 97.5%) than the control group (27/102, 26%, p 0.001, chi-square). HPV was detected in 6 of 25 (24%) HNSCC tumors by PCR, five were typed as HPV 16 and one as HPV 26/69; five of these tumors (83%) were located in the oropharynx. EBV, HSV-1, HSV-2, and HHV-8 were

Background: Rate of coinfection with human immunodeficiency virus (HIV) and hepatitis C virus (HCV) varies in different countries. This may be attributable to common transmission routes as well as social, economic, and cultural factors. Objectives: The purpose of this study was to investigate the prevalence and risk factors of HCV infection among HIV-positive patients in Istanbul, Turkey. Patients and Methods: Since January 2006 to November 2013, 949 HIV-positive patients that were enrolled in this study by ACTHIV-IST (Action Against HIV in Istanbul) Study Group, which consists of five centers to follow up HIV-positive patients in Istanbul. Epidemiologic and clinical data were collected retrospectively from medical records and were transferred to an HIV database system. Results: Among 949 patients, 84% were men and the mean age was 37.92 ± 11.54 years (range, 17-79). The most frequent route of transmission was heterosexual intercourse (48.8%), followed by men having sex with men (30.5%). Only nine patients (0.9%) had history of injection drug use (IDU). The prevalence of HIV/HCV coinfection was 0.9% (9:949). The IDU rate was 44.4% (4:9) in patients with HIV/HCV coinfection (three of them were not Turkish citizens), whereas this rate was only 0.6% (5:881) in patients with only HIV infection (P < 0.01). Genotypes 1b, 2a/2c, and 3 were determined in five, one, and two patients, respectively. Genotype could not be determined in one patient. History of residence in a foreign country (P < 0.01) and imprisonment (P < 0.01) were also considered as risk factors in terms of HIV/HCV coinfection. Conclusions: Prevalence of HIV/HCV coinfection is considerably low in Turkey. The extremely rare prevalence of IDU might have a role in this low prevalence. PMID:25337142

A survey conducted in September 1987 among medical doctors and dental surgeons in Singapore found that most respondents expressed personal reservations and inadequacies in dealing with AIDS/HIV-positive patients and homosexuals. They were also concerned about exposure of their staff to AIDS patients and their likely reactions towards treating these patients. The risk of contagion with AIDS was a major deterrent expressed. The majority of the health professionals had no experience in the management of AIDS related conditions. Although many indicated interest in training, only less than half were willing to undergo what they perceived as the more effective clinically based training themselves.

The prevalence of intestinal parasitic diseases and their associated factors has been investigated in HIV populations from the Island of Bioko, Equatorial Guinea. The feces of 310 participants from the island of Bioko (260 HIV-positive and 50 HIV-negative) were analyzed by microscopic observation. Immunochromatography was also used to diagnose Giardia, Entamoeba histolytica and Cryptosporidium spp. In addition, patients were asked for sociodemographic, economic and academic status, and CD4+ T cell counts were recorded. For HIV-positive patients, the prevalence of infection by intestinal parasites was 81.5% (212/260), 83.8% (218/260) by pathogenic helminths and 55.4% (168/260) by pathogenic protozoa (E. histolytica/dispar and Giardia duodenalis). Gender association was found between the infection by Ascaris and Schistosoma, a higher proportion being found in women; and between Entamoeba and the place of residence, a higher proportion being observed in the urban belt. Strongyloides stercoralis and Chilomastix mesnili appeared only in the people of this group, all the cases of Chilomastix being in females. For HIV-negative participants, the prevalence of infection by intestinal parasites was 74.0% (37/50), 90.0% (45/50) by pathogenic helminths and 66.0% (43/50) by pathogenic protozoa. Gender, educational level and low hygiene were associated with intestinal parasitic infection. When comparing the two groups (HIV-positive and HIV-negative), statistical association between HIV co-infection and infection by Giardia and Entamoeba was found. Diarrhea was also associated with intestinal parasitic infection in the HIV-positive group. Not only do our findings reflect high rates of intestinal parasitic infections in HIV-positive people, but also in the HIV-negative group, suggesting a closer relationship between sanitary status and living conditions than with immune status, and thus they highlight the need to carry out health education policies in the population. In addition

The aim of this cross-sectional study was to evaluate the prevalence and risk factors of medium-grade proteinuria (100-500 mg/g creatinine) among HIV-positive adults. Spot urine samples of HIV-positive adults without known renal disease were analyzed quantitatively between January 2009 and February 2011. Demographic and medical data were collected. Multivariate regression models for different patterns of proteinuria were constructed. Among 411 patients, 18 (4.4 %) presented albuminuria >300 mg/g creatinine and/or proteinuria >500 mg/g creatinine and were excluded from further analyses. Among the study population of 393 patients, 181 (46.1 %) had no significant proteinuria or albuminuria (<100 and <30 mg/g creatinine, respectively), 60 (15.3 %) had moderate albuminuria, while 152 (38.7 %) had proteinuria without albuminuria, suggesting tubular proteinuria. Independent predictors for medium-grade tubular proteinuria in multivariate analysis were exposure to tenofovir (DF), a CD4 nadir <500/µl, older age, and anti-HCV-antibodies. There was no association with classic renal risk factors like diabetes mellitus and arterial hypertension, or with estimated glomerular filtration rate (eGFR). We detected significant proteinuria in 230 (56.0 %) of 411 HIV-positive patients. Among this group, 152 (66.1 %) had medium-grade proteinuria without albuminuria, which was significantly associated with exposure to tenofovir, older age, a lower CD4 nadir and Hepatitis C. Nephrologic or HIV treatment guidelines fail to detect most of these patients but rather identify patients with high cardiovascular risk. In the absence of an association with eGFR the role of medium-grade tubular proteinuria as a potential early marker of chronic kidney disease remains unclear. Prospective studies are needed.

From September 2008 to December 2011, we enrolled and followed-up 247 HIV-negative, 88 untreated and 32 treated HIV-positive female sex workers (FSWs), as well as 238 untreated and 115 treated HIV-positive patients from the general population (GP) of Cotonou, Benin. We wanted to assess the effect of antiretroviral therapy (ART) on sexual risk-taking in FSWs and patients from the GP. We used multivariate log binomial regression models for repeated measures to compare risky behaviours reported during pre-ART and post-ART visits and we performed linear time-trend analyses to assess changes in condom use in all five groups. At 58.8% of pre-ART and 45.3% of post-ART visits (adjusted p-value=0.293), treated FSWs have reported ≥16 clients during the last week of work. Inconsistent condom use with clients over the same period decreased by more than 50% (from 20.7 to 10.0%, adjusted p-value=0.082). In treated patients from the GP, inconsistent condom use with regular partners during the last four months was reported at 52.8% of pre-ART and 53.5% of post-ART visits (p=0.778). Reported casual sex was stable (36.8% versus 38.7%, adjusted p-value=0.924). In linear time-trend analyses, there was a significant downward trend in inconsistent condom use at the early stage of the study and stability thereafter in all HIV-negative and HIV-positive FSWs. There was no negative alteration in sexual behaviour following ART initiation either inpatients from the GP or in FSWs. The results underscore the key role of concomitant sexual risk-reduction strategies.

There is limited literature on the known risk of HIV transmission during amniocentesis. Before the introduction of highly active antiretroviral therapy (HAART), amniocentesis was avoided owing to the increased risk of HIV transmission. Recent literature suggests that it is safe to perform amniocentesis in women on HAART with undetectable viral loads. In South Africa (SA), many women access antenatal care late in pregnancy and there is often insufficient time to attain undetectable viral loads within a pre-viability period. Guidelines and recommendations for invasive testing in HIV-positive women in the SA setting are lacking. This article provides recommendations to healthcare practitioners who are faced with an HIV-positive patient requiring amniocentesis.

The lower tuberculosis incidence reported in human immunodeficiency virus (HIV)-positive individuals receiving combined antiretroviral therapy (cART) is difficult to interpret causally. Furthermore, the role of unmasking immune reconstitution inflammatory syndrome (IRIS) is unclear. We aim to estimate the effect of cART on tuberculosis incidence in HIV-positive individuals in high-income countries. The HIV-CAUSAL Collaboration consisted of 12 cohorts from the United States and Europe of HIV-positive, ART-naive, AIDS-free individuals aged ≥18 years with baseline CD4 cell count and HIV RNA levels followed up from 1996 through 2007. We estimated hazard ratios (HRs) for cART versus no cART, adjusted for time-varying CD4 cell count and HIV RNA level via inverse probability weighting. Of 65 121 individuals, 712 developed tuberculosis over 28 months of median follow-up (incidence, 3.0 cases per 1000 person-years). The HR for tuberculosis for cART versus no cART was 0.56 (95% confidence interval [CI], 0.44-0.72) overall, 1.04 (95% CI, 0.64-1.68) for individuals aged >50 years, and 1.46 (95% CI, 0.70-3.04) for people with a CD4 cell count of <50 cells/μL. Compared with people who had not started cART, HRs differed by time since cART initiation: 1.36 (95% CI, 0.98-1.89) for initiation <3 months ago and 0.44 (95% CI, 0.34-0.58) for initiation ≥3 months ago. Compared with people who had not initiated cART, HRs <3 months after cART initiation were 0.67 (95% CI, 0.38-1.18), 1.51 (95% CI, 0.98-2.31), and 3.20 (95% CI, 1.34-7.60) for people <35, 35-50, and >50 years old, respectively, and 2.30 (95% CI, 1.03-5.14) for people with a CD4 cell count of <50 cells/μL. Tuberculosis incidence decreased after cART initiation but not among people >50 years old or with CD4 cell counts of <50 cells/μL. Despite an overall decrease in tuberculosis incidence, the increased rate during 3 months of ART suggests unmasking IRIS.

A survey of the intestinal parasites among the HIV positive asymptomatic injecting drug users (IDUs) in Manipur State in North-east India revealed the presence of three protozoan and two nematode species. Of these, the two opportunistic parasitic protozoans i.e., Cryptosporidium sp. (94.4 percent) and Isospora sp. (10.7 percent) were predominant over Entamoeba histolytica (5.6 percent), while non-opportunistic parasitic nematodes, i.e. Ascaris lumbricoides (4.6 percent) and Ancylostoma sp. (1 percent) were the less frequently detected ones. In all cases, the fungal flora were predominant. Candida sp. was more often encountered compared to Cladosporium and Humicloa. The study also revealed that although these individuals showed no gastro-intestinal disorders like diarrhoea, they still harbour these opportunistic and non-opportunistic parasites and act as carriers, particularly of the former category, in the community via contaminated water and open defaecation practices.

We attempted to determine the seropositivity of HIV-positive patients to other antibodies (herpes, CMV, rubella, varicella, hepatitis B, hepatitis C, syphilis, chlamydia, mumps, toxoplasmosis). The study was carried out at the Prenatal Diagnosis and Therapy Centre of a Tertiary Hospital in Lagos, Nigeria. A total of 70 patients (50 females and 20 males) attending the centre between June 1997 and December 2005 who were screened and found to be HIV-seropositive were further screened for herpes simplex IgG/IgM, CMV IgG/IgM, rubella IgG/IgM, varicella IgG/IgM, mumps IgG/IgM, toxoplasmosis IgG/IgM, chlamydia IgG/IgM, hepatitis B and hepatitis C IgG/IgM using ELISA kits and syphilis (THPA) using the HAE method. Our study showed that a large number of HIV-positive patients are carriers of other antibodies and should be screened for them before therapy.

Anal carcinoma, a common disease in HIV-positive patients, is usually treated with chemoradiotherapy. Generally tolerance was poor before the availability of highly active antiretroviral therapies. We report our experience of treating anal carcinoma in the era of new antiviral drugs. Between 1997 and 2001, nine men on highly active antiretroviral therapies with good immune status before chemoradiotherapy received concomitant chemoradiotherapy consisting of 5-fluorouracil and cisplatinum, and high-dose radiotherapy (60-70 Gy) for anal carcinoma. Six cancers were Stage I, two were Stage II, and one was Stage III. CD4+ cell counts were <200/ml for four patients, between 200/ml and 500/ml for four, and >500/ml for one. All patients received the planned dose of radiation (> or = 60 Gy). The chemotherapy dose was reduced 25 percent in six patients. Overall treatment time was 58 days. Grade 3 hematologic or skin toxicity occurred in four patients. No association was observed between high-grade toxicity and CD4+ cell count. None of the patients developed opportunistic infections during follow-up. Eight patients were disease-free after a median follow-up of 33 months. Among them, four had no or minor anal function impairment at the last follow-up visit. One patient with T4N2 disease relapsed locally one year after treatment and underwent salvage abdominoperineal excision. High-dose chemoradiotherapy for anal carcinomas is feasible with low toxicity in HIV-positive patients treated with highly active antiretroviral therapies. Local control is similar to that obtained for HIV-negative patients.

Hepatitis B virus (HBV) and human immunodeficiency virus (HIV) share transmission mechanisms and thus coinfection is frequent. Active immunization against HBV is essential in HIV patients. Reports using standard and reinforced HBV vaccination schedules vary widely in seroconversion rates depending on the characteristics of the included patients. Regional data concerning HBV vaccination in HIV patients are scarce. We aim to determine the serological response to HBV vaccination using standard schedule in HIV-positive patients and to evaluate characteristics that predict seroconversion. We performed a single centre prospective study of HBV vaccination with standard schedule in HIV-positive patients. Adults with negative markers of HBV infection were included between November 2012 and December 2014. Anti-HBs titres were measured 4-8 weeks after completion of vaccination schedule. Clinical, laboratory values and HIV characteristics were analyzed to determine their association with seroconversion and adherence to the HBV vaccination schedule. The study included 245 HIV-positive patients, 68.9% were male and the mean age was 42.1 years. A total of 80.7% of the patients had undetectable HIV viral loads, 86.1% had CD4 counts >200, and 94.7% were on HAART. The response to vaccination was positive in 62% (95% CI, 56-68%) and mean anti-HBs titres of 646 IU/ml. 85.5% of the responders had anti-HBs titres >100 IU/ml. An age less than 45 years, no tobacco use and a CD4/CD8 ratio >0.4 were associated with seroconversion in multivariate analysis. The seroconversion rates were 86% in the subgroup of patients who met these criteria. A total of 97.9% of the study population completed the vaccination schedule. The CD4/CD8 ratio was the primary factor associated with positive serological conversion in the multivariate analysis. The seroconversion rates were higher in a selected group of patients who were particularly suitable for the use of the standard HBV vaccination schedule

BACKGROUND Kaposi sarcoma (KS) is the most frequent skin cancer in solid organ recipients, and also a typical malignancy in HIV-infected persons. CASE REPORT We describe here a rare case of primary nodal KS without mucocutaneous manifestations, diagnosed in a 20-year-old HIV/HBV co-infected patient 12 months after liver transplantation (LT), the first one performed in a HIV-positive patient in Poland. The course of the disease was very aggressive; the patient died four weeks after general lymphadenopathy appearance. In the autopsy, KS infiltration was found in numerous lymph nodes and in the lung' apexes without skin or other organs' involvement. CONCLUSIONS In conclusion, posttransplant KS may present as general lymphadenopathy without mucocutaneous manifestations, thus mimicking posttransplant lymphoproliferative disorder, which is often the first clinical suspicion. Lymph node histopathological examination is necessary to make the right diagnosis.

This case study explores the incidence of rhabdomyolysis in a HIV positive patient that was taking a lipid lowering drug and a protease inhibitor concurrently while under chiropractic treatment for generalized muscular soreness. Dyslipidemia is a very common problem both in the general and HIV population, with many patients being prescribed lipid lowering drugs. While extremely rare, adverse effects of lipid lowering drugs have been documented to include myopathy such as rhabdomyolysis. It is imperative that chiropractors are aware of the possible adverse side effect of lipid lowering drug therapy in their patients complaining of musculoskeletal pain. It is even more important that chiropractors treating the HIV population are aware of the potential interactions between these medications and protease inhibitors to cause myopathy.

Background Determine-TB LAM assay is a urine point-of-care test useful for TB diagnosis in HIV-positive patients. We assessed the incremental diagnostic yield of adding LAM to algorithms based on clinical signs, sputum smear-microscopy, chest X-ray and Xpert MTB/RIF in HIV-positive patients with symptoms of pulmonary TB (PTB). Methods Prospective observational cohort of ambulatory (either severely ill or CD4<200cells/μl or with Body Mass Index<17Kg/m2) and hospitalized symptomatic HIV-positive adults in Kenya. Incremental diagnostic yield of adding LAM was the difference in the proportion of confirmed TB patients (positive Xpert or MTB culture) diagnosed by the algorithm with LAM compared to the algorithm without LAM. The multivariable mortality model was adjusted for age, sex, clinical severity, BMI, CD4, ART initiation, LAM result and TB confirmation. Results Among 474 patients included, 44.1% were severely ill, 69.6% had CD4<200cells/μl, 59.9% had initiated ART, 23.2% could not produce sputum. LAM, smear-microscopy, Xpert and culture in sputum were positive in 39.0% (185/474), 21.6% (76/352), 29.1% (102/350) and 39.7% (92/232) of the patients tested, respectively. Of 156 patients with confirmed TB, 65.4% were LAM positive. Of those classified as non-TB, 84.0% were LAM negative. Adding LAM increased the diagnostic yield of the algorithms by 36.6%, from 47.4% (95%CI:39.4–55.6) to 84.0% (95%CI:77.3–89.4%), when using clinical signs and X-ray; by 19.9%, from 62.2% (95%CI:54.1–69.8) to 82.1% (95%CI:75.1–87.7), when using clinical signs and microscopy; and by 13.4%, from 74.4% (95%CI:66.8–81.0) to 87.8% (95%CI:81.6–92.5), when using clinical signs and Xpert. LAM positive patients had an increased risk of 2-months mortality (aOR:2.7; 95%CI:1.5–4.9). Conclusion LAM should be included in TB diagnostic algorithms in parallel to microscopy or Xpert request for HIV-positive patients either ambulatory (severely ill or CD4<200cells/μl) or hospitalized.

Background Individuals with impaired immunity are at higher risk of perianal diseases. Concerning complex anal fistulas impaired healing and complication rates are also higher. Definitive treatment of a fistula aims controlling the purulent discharge and prevents its recurrence. It depends mainly on the trajectory of the fistula and the underlying disease. We present a case of a HIV-positive patient with a complex extrasphincteric anal fistula who was treated successfully with fibrin glue application. We further, discuss tips and tricks when applying fibrin glue as plugging material in complex anal fistulas. Case presentation A sixty-one-year-old HIV-positive male referred to us for warts and extrasphincteric fistula. Because of the patients' immunological status, we opted against surgery and recommended fibrin glue plugging. The patient was discharged the same day. A follow-up examination was performed 5 days after the initial fibrin glue application showing that the fistula canal was obstructed. Three months and a year post-intervention the fistula tract remains closed. Conclusion The best treatment for a disease gives at least the same result with the other treatments with minimised risk for the life of the patient and minimal application effort. Conservative closure of fistula with fibrin plugging is simple, safe and with less morbidity than surgery. Our patient was successfully treated without endangering his life despite his precarious medical state. Not everybody believes in the effectiveness of fibrin glue application, however we consider this solution in cases of complex fistulas at least as primary procedure in special populations such as the immunosupressed.

The purpose of this study was to determine the prevalence of enteric bacteria and yeasts in biofilm of 80 HIV-positive patients with plaque-associated gingivitis or necrotizing periodontitis. Patients were subjected to extra, intra oral and radiographic examinations. The oral hygiene, bleeding on probing, gingival conditions, and attachment loss were evaluated. Clinical specimens were collected from gingival crevices or periodontal pockets, transferred to VMGA III, diluted and transferred to Sabouraud Dextrose agar with 100 μg/ml of chloramphenicol, peptone water, EVA broth, EMB agar, SS agar, Bile esculin agar and Brilliant green agar. Isolation of yeasts was carried out at room temperature, for 3-7 days; and for the isolation of enteric microorganisms plates were incubated at 37°C, for 24-48 h. The yeasts identification was performed according to the carbon and nitrogen assimilation, fermentation of carbohydrates and germ tube formation. Bacteria were identified according to their colonial and cellular morphologies and biochemical tests. Yeasts were identified as Candida albicans and its occurrence was more common in patients with CD4+ below 200/mm3 and was affected by the extension of periodontal involvement (P = 0.0345). Enteric bacteria recovered from clinical specimens were identified as Enterobacter sakazakii, Enterobacter cloacae, Serratia liquefaciens, Klebsiella oxytoca and Enterococcus sp. Enterobacteriaceae and enterococci were detected in 32.5% of clinical samples from patients with necrotizing periodontitis. In conclusion, non-oral pathogenic bacteria and C. albicans were more prevalent in periodontal sites of HIV-positive patients with necrotizing periodontitis and chronic gingivitis. PMID:24031212

Blood stream tuberculosis (TB), caused by Mycobacterium tuberculosis (MTB) is common among HIV-positive patients, turning rapidly fatal unless detected and treated promptly. Blood culture is currently the standard test for the detection of MTB in whole blood but results take weeks; patients deteriorate markedly and often die before a diagnosis of blood stream TB is made. Rapid molecular tests on whole blood, with potential for same day diagnosis of blood stream TB usually show low sensitivity due to the problem of insufficient MTB DNA template when extraction is performed directly on low blood volumes. This study assessed the influence of blood volume on the sensitivity of a HyBeacon PCR assay-the FluoroType MTB (Hain Lifescience, Nehren, Germany) on direct detection of MTB in whole blood. Prospective recruitment of HIV-positive patients with clinical suspicion of blood stream TB but not on anti-TB or HIV drug treatment was done. Venous blood samples were collected and DNA extracted using the MolYsis (Molzym, Bremen, Germany) methods; for study A, from duplicate 1 ml (42 patients) and for study B (31 patients) from 9 ml EDTA blood samples. The FluoroType MTB PCR assay targeting an IS6110 sequence was performed and results compared with blood culture. The diagnostic sensitivity and specificity of the FluoroType MTB PCR in study A was 33% and 97%, respectively. Corresponding values in study B were 71% and 96%, respectively. In both studies, one case each of blood culture-negative blood stream TB was detected with the FluoroType MTB PCR assay. The median time to positivity of blood culture was 20.1 (range 12-32) for study A and 19.9 days (range 15-30) for study B. Larger blood volumes (9 ml) improved and gave acceptable sensitivity of direct PCR diagnosis of blood stream TB.

Background Reducing substance use and unprotected sex by HIV-positive persons improves individual health status while decreasing the risk of HIV transmission. Despite recommendations that health care providers screen and counsel their HIV-positive patients for ongoing behavioral risks, it is unknown how to best provide “prevention with positives” in clinical settings. Positive Choice, an interactive, patient-tailored computer program, was developed in the United States to improve clinic-based assessment and counseling for risky behaviors. Methodology and Findings We conducted a parallel groups randomized controlled trial (December 2003–September 2006) at 5 San Francisco area outpatient HIV clinics. Eligible patients (HIV-positive English-speaking adults) completed an in-depth computerized risk assessment. Participants reporting substance use or sexual risks (n = 476) were randomized in stratified blocks. The intervention group received tailored risk-reduction counseling from a “Video Doctor” via laptop computer and a printed Educational Worksheet; providers received a Cueing Sheet on reported risks. Compared with control, fewer intervention participants reported continuing illicit drug use (RR 0.81, 95% CI: 0.689, 0.957, p = 0.014 at 3 months; and RR 0.65, 95% CI: 0.540, 0.785, p<0.001 at 6 months) and unprotected sex (RR 0.88, 95% CI: 0.773, 0.993, p = 0.039 at 3 months; and RR 0.80, 95% CI: 0.686, 0.941, p = 0.007 at 6 months). Intervention participants reported fewer mean days of ongoing illicit drug use (-4.0 days vs. -1.3 days, p = 0.346, at 3 months; and -4.7 days vs. -0.7 days, p = 0.130, at 6 months) than did controls, and had fewer casual sex partners at (−2.3 vs. −1.4, p = 0.461, at 3 months; and −2.7 vs. −0.6, p = 0.042, at 6 months). Conclusions The Positive Choice intervention achieved significant cessation of illicit drug use and unprotected sex at the group-level, and modest individual

Since the arrival of antiretroviral (ARV) therapy, HIV has become better characterized as a chronic disease rather than a terminal illness, depending in part on one’s ability to maintain relatively high levels of adherence. Despite research concerning barriers and facilitators of ARV adherence behavior, relatively little is known about specific challenges faced by HIV-positive persons who report “taking a break” from their ARV medications. The present study employed the Information-Motivation-Behavioral Skills Model of ARV Adherence as a framework for understanding adherence-related barriers that may differentiate between non-adherent patients who report “taking a break” versus those who do not report “taking a break” from their ARV medications. A sample of 327 HIV-positive patients who reported less than 100% adherence at study baseline provided data for this research. Participants who reported “taking a break” from their HIV medications without first talking to their healthcare provider were classified as intentionally non-adherent, while those who did not report “taking a break” without first talking with their healthcare provider were classified as unintentionally non-adherent. Analyses examined differences between intentionally versus unintentionally non-adherent patients with respect to demographic characteristics and responses to the adherence-related information, motivation, and behavioral skills questionnaire items. Few differences were observed between the groups on demographics, adherence-related information or adherence-related motivation; however, significant differences were observed on about half of the adherence-related behavioral skills items. Implications for future research, as well as the design of specific intervention components to reduce intentionally non-adherent behavior, are discussed. PMID:20552469

Introduction Successful global treatment as prevention (TasP) requires identifying HIV-positive individuals at high risk for transmitting HIV, and having impact via potential infections averted. This study estimated the frequency and predictors of numbers of HIV transmissions and bacterial sexually transmitted infection (STI) acquisition among sexually active HIV-positive individuals in care from three representative global settings. Methods HIV-positive individuals (n=749), including heterosexual men, heterosexual women and men who have sex with men (MSM) in HIV care, were recruited from Chiang Mai (Thailand), Rio De Janeiro (Brazil) and Lusaka (Zambia). Participants were assessed on HIV and STI sexual transmission risk variables, psychosocial characteristics and bacterial STIs at enrolment and quarterly for 12 months (covering 15 months). Estimated numbers of HIV transmissions per person were calculated using reported numbers of partners and sex acts together with estimates of HIV transmissibility, accounting for ART treatment and condom use. Results An estimated 3.81 (standard error, (SE)=0.63) HIV transmissions occurred for every 100 participants over the 15 months, which decreased over time. The highest rate was 19.50 (SE=1.68) for every 100 MSM in Brazil. In a multivariable model, country×risk group interactions emerged: in Brazil, MSM had 2.85 (95% CI=1.45, 4.25, p<0.0001) more estimated transmissions than heterosexual men and 3.37 (95% CI=2.01, 4.74, p<0.0001) more than heterosexual women over the 15 months. For MSM and heterosexual women, the combined 12-month STI incidence rate for the sample was 22.4% (95% CI=18.1%, 27.3%; incidence deemed negligible in heterosexual men). In the multivariable model, MSM had 12.3 times greater odds (95% CI=4.44, 33.98) of acquiring an STI than women, but this was not significant in Brazil. Higher alcohol use on the Alcohol Use Disorders Identification Test (OR=1.04, 95% CI=1.01, 1.08) was also significantly associated

Introduction Disclosure of HIV status especially to sexual partners is an important prevention goal. This study was conducted to determine the prevalence of HIV status disclosure and the factors associated with disclosure by HIV positive patients attending the adult Anti-retroviral therapy (ART) clinic in State Specialist Hospital Gombe (SSHG) a secondary health facility in north-eastern Nigeria. Methods We conducted a cross sectional study among adult HIV positive patients enrolled into the HIV/AIDS programme of SSHG. Study participant were sampled using a systematic random sampling. Interviewer administered questionnaire was used to collect data on socio-demographic characteristics, disclosure status and factors associated with disclosure. Data was analyzed using Epi-info software. Results Of the 198 (99%) respondents, 159 (80.3%) were females. The mean age of respondents was 32.9years (SD ± 9.5). Sixty percent of the respondents were married. Most (97.5%) had disclosed their HIV status and majority (36.8%) disclosed to their spouses. Sixty four percent of the respondents had treatment supporter and spouses (42.9%) were their choice of a treatment supporter. Disclosure of HIV status was found to be associated with age < 40years Adjusted Odds Ratio (AOR) 38.16; 95% Confidence Interval (CI) 2.42-602.61. Gender, employment status, educational level, duration of infection and marital status were not found to be significantly associated with disclosure of HIV status. Conclusion Disclosure of HIV status was high in the study population. Spouses were the most preferred choice of persons to disclose HIV status to, and the most adopted as treatment supporter. HIV status disclosure is encouraged after diagnosis because of its importance especially among couples. PMID:25328623

Squamous cell carcinoma of anus (SCCA) is one of the most frequent non-AIDS-defining diseases in HIV patients, mainly in men who have sex with men (MSM), and it is associated with human papillomavirus (HPV) infection.To determine the prevalence of high-risk HPV (HR-HPV) genotypes, premalignant lesions (HSIL) and SCCA in a cohort of HIV-positive MSM; to study the distribution of HPV genotypes according to anal histology results; and to analyze risk factors for this infection.This prospective single-center study was conducted between May 2010 and September 2016. At the study visit, cotton swabs were used to collect anal samples for cytology study in ThinPrep Pap Test liquid medium (Thin Prep Processor 2000, Hologic Corp, USA), and for HPV PCR (Linear Array HPV Genotyping Test). After, high-resolution anoscopy (HRA) (Zeiss 150 fc) was carried out. Logistic regression analysis was performed to identify risk factors for HR-HPV infection.The study included 319 patients, with mean age of 36.7 years; HR-HPV was detected in 81.3%. The prevalence of HSIL was 13.5% and SCCA was 0.3%. With regard to the distribution of HPV genotypes according to histology results, HPV 16 was the most frequent genotype in normal anal mucosa (26.7%), in LSILs (36.9%), and in HSILs (38%). In multivariate analysis, CD4 nadir < 200 cells/μL was the factor associated with infection by HR-HPV (OR 3.66, 95% CI 1.05%-12.75%).HIV-positive MSM showed a high prevalence of HSIL+ lesions and of infection by oncogenic HPV, which appears to be favored by a deficient immune system. HPV 16 was the most frequently isolated genotype in anal mucosa, regardless of lesion type.

The immunosuppresion in HIV patients makes them highly susceptible to microbial infections. The aim of the study was to establish whether HIV stage (as depicted by CD4+ T lymphocyte counts) could independently be associated with periodontal status (as revealed by the measurement of clinical indices). One hundred and twenty HIV-infected patients attending an infectious diseases clinic in the Western Cape, South Africa were included in the study. The periodontal clinical indices such as plaque index, gingival index, pocket probing depth and clinical attachment levels were measured on the mesial aspect of the six Ramfjord teeth. The CD4 + T cell counts were taken from the patients' medical records and patients' HIV stage determined and grouped according to their CD4+ T cell counts into A (<200 cells /mm3), B (200-500 cells /mm3) and C (>500 cells /mm3). The mean age of 120 HIV-positive patients was 33.25 years and the mean CD4 + T cell count was 293.43 cells/mm3. The probing depth and clinical attachment loss were found to be significantly associated with the total CD4 + T cell counts but not with HIV stage. Significant correlations were found between age and all clinical indices except for clinical attachment loss. No correlation was found between age and HIV stage of the patients. The use of antiretroviral therapy was significantly associated with probing depth and clinical attachment loss, but not with plaque nor gingival index. Significant associations were observed between smoking and all of the clinical indices except for the gingival index. A significant association was observed between the use of interdental aids and all the clinical indices except for probing depth, while brushing was significantly associated with plaque index only. CD4 + T cell counts were significantly associated with brushing frequency (p = 0.0190) and the use of interdental aids (p = 0.0170). The findings of this study conclude that HIV stage, ART and age are not independent risk factors

Introduction Absolute CD4 T cell count and plasma viral load have been established as predictors of HIV disease progression, and CD4 T cell count is used as an indicator for initiation of antiretroviral therapy. Following long-term therapy, patients generally present with significant CD4 T cell recovery contrasting with persistently elevated CD8 T cell counts, which leads to a partial restoration of CD4:CD8 ratio. This review focuses on the relevance of the CD4:CD8 ratio on clinical outcomes, immune dysfunction and HIV reservoir size in long-term treated patients. Method We conducted a comprehensive literature review of publications in English language using major electronic databases. Our search was focused on factors contributing to CD4:CD8 T cell ratio and clinical outcome in adult HIV-positive patients in the context of treated infection. Discussion Low CD4:CD8 ratio has been linked to ageing and acts as a predictor of mortality in the general population. This ratio may represent the combined effects of inflammation and immunological changes called “inflammaging.” Although the mechanisms underlying partial correction of the CD4:CD8 ratio and persistently elevated CD8 T cell count in long-term treated patients remain poorly understood, it has been recently indicated that patients with optimal CD4 T cell recovery and low CD4:CD8 ratio still harbour increased immune activation, an immune senescent phenotype and have a higher risk of non-AIDS morbidity and mortality. This review reconsiders CD4:CD8 ratio in the light of advances in the understanding of immune dysfunction and examines its pathophysiological features and implications on clinical outcome and HIV reservoir size in long-term treated HIV-positive adults. Conclusion The CD4:CD8 ratio can contribute to the immunological evaluation of treated patients in a long-term follow-up and may be applied for monitoring both immune dysfunction and viral reservoir size in immune-based clinical trials.

This study contains a descriptive analysis of histoplasmosis in AIDS patients between 2006 and 2010 in the state of Ceará, Brazil. Additionally, the in vitro susceptibility of Histoplasma capsulatum isolates obtained during this period was assessed. We report 208 cases of patients with histoplasmosis and AIDS, describing the epidemiological, clinical, laboratory and therapeutic aspects. The in vitro antifungal susceptibility test was carried out by the microdilution method, according to Clinical and Laboratory Standards Institute, with H. capsulatum in the filamentous and yeast phases, against the antifungals amphotericin B, fluconazole, itraconazole, voriconazole and caspofungin. In 38.9% of the cases, histoplasmosis was the first indicator of AIDS and in 85.8% of the patients the CD4 cell count was lower than 100 cells/mm(3). The lactate dehydrogenase levels were high in all the patients evaluated, with impairment of hepatic and renal function and evolution to death in 42.3% of the cases. The in vitro susceptibility profile demonstrated there was no antifungal resistance among the isolates evaluated. There was a significant increase in the number of histoplasmosis cases in HIV-positive patients during the period surveyed in the state of Ceará, northeastern Brazil, but no antifungal resistance among the recovered isolates of H. capsulatum.

Introduction HIV-associated lipodystrophy syndrome causes systemic metabolic alterations and psychological distress that worsen the quality of life of these patients. An early detection should be considered to efficiently treat it. Objective criteria or reference indices are needed for an early diagnosis. Bioelectrical Impedance Analysis (BIA) is an operator-independent, repeatable and non-invasive method of body composition evaluation that is less expensive than dual-energy X-ray absorptiometry (DXA) and/or CT scans. The aims of this pilot study were to validate the data obtained by BIA to measure fat mass in HIV-positive patients with/without lipoatrophy and to determine if BIA correctly diagnoses lipoatrophy in HIV-positive patients. Methods Thirty-nine participants were included in this preliminary study. Fourteen were HIV-negative (eight men) whereas 25 were HIV-positive patients (17 men). Eleven of the HIV-positive patients were classified as lipoatrophic according to subjective evaluation by the physicians. Total and regional body composition was measured in basal conditions by DXA and by BIA. To obtain abdominal CT scan fat values, transverse slices with 6-mm thickness were acquired at the L4-L5 intervertebral space. Results BIA measurements of total and regional body fat were significantly correlated with those obtained by DXA (p < 0.05 to <0.01) in HIV-positive patients. However, agreement between methods was poor as not very high ICC (intraclass correlation coefficient) values were observed. BIA and DXA showed higher ICC values in lipoatrophic patients. The visceral index obtained by BIA was correlated with total and visceral fat in L4 measured by CT scan (r = 0.607 and r = 0.617, respectively, p < 0.01) in HIV-positive patients. The Fat Mass Ratio (FMR) calculated by BIA did not correlate or agree with DXA values. Conclusions Multi-frequency BIA could be an effective method to evaluate the evolution of total and regional fat composition in HIV-positive
Cuba experienced a substantial increase in the number of HIV cases in 1996 due primarily to a growth of foreign tourism and an increase in prostitution, health officials said. The Juventud Rebelde newspaper said that since HIV/AIDS testing began in 1985, government-run hospitals and clinics have detected 1609 HIV-positive cases. In 1995 the total was reported at 1196, meaning that 413 new cases were detected in 1996. This compared with only 97 new cases reported during 1995. HIV infection among the island's 11 million inhabitants has remained relatively low due to a massive testing program and a public health infrastructure that provides universal and free medical treatment. Cuba was a pioneer in the use of interferon on those testing HIV-positive. Cuba produces its own interferon, which prolongs the life expectancy of patients, and also reagents for AIDS testing. There are special sanitariums for AIDS patients in most of Cuba's 12 provinces. Cuban adults who test HIV-positive are required to enter the sanitarium in a policy reminiscent of the way tuberculosis patients were tested in the US earlier in this century. Officials said the isolation of patients in sanitariums has been somewhat relaxed over past years by introducing greater flexibility in allowing persons who are considered reliable to live at home or make prolonged visits.

There are few reports about physician and patient attitudes about antiretroviral therapy. Reports on physician perceptions of HIV-positive patients and patients' perceptions of their physicians are even scarcer. The International Association of Physicians in AIDS Care conducted surveys of HIV-treating physicians, and a separate set of HIV-positive patients. Physicians completed an online questionnaire. Patients completed a written questionnaire. Physicians and patients agreed on several issues, including the priority of viral suppression when making treatment decisions and the treatment-limiting impact of side effects. However, they had diverging treatment goals in mind and differing impressions of the type and incidence of side effects. There were also sharp differences in physicians' estimates of how well patients understand HIV disease and its treatment. The differences revealed through these surveys underline the need to conduct a systematic study of physician and patient attitudes about antiretroviral therapy, as well as physician-patient communication.

Objective We examined HIV transmission potential of patients in care by analyzing the amount of person-time spent above a viral load threshold that increases risk for transmission. Design Observational cohort and supplemental data. Methods The cohort included HIV patients who received care at six HIV clinics in the United States, from 1 April 2009 to 31 March 2013, and had two or more viral load tests during this interval. Person-time (in days) above a viral load of 1500 copies/ml out of the total observation time was determined by inspecting consecutive pairs of viral load results and the time intervals between those pairs. The person-time rate ratios comparing demographic and clinical subgroups were estimated with Poisson regression. Results The cohort included 14 532 patients observed for a median of 1073 days with a median of nine viral load records. Ninety percent of the patients had been prescribed antiretroviral therapy. On average, viral load exceeded 1500 copies/ml during 23% of the patients’ observation time (average of 84 days per year, per patient). Percentage of person-time above the threshold was higher among patients who had more than a fourth of their viral load pairs exceeding a 6-month interval (34% of observation time), patients not on antiretroviral therapy (58% of time), new/re-engaging patients (34% of time), patients 16–39 years of age (32% of time), and patients of black race (26% of time). Conclusion HIV patients in care spent an average of nearly a quarter of their time with viral loads above 1500 copies/ml, higher among some subgroups, placing them at risk for potentially transmitting HIV to others.

Background Antiretroviral therapy (ART) has been life saving for hundreds of thousands of Ethiopians. With increased availability of ART in recent years, achievement of optimal adherence and patient retention are becoming the greatest challenges in the management of HIV/AIDS in Ethiopia. However, few studies have explored factors influencing medication adherence to ART and retention in follow-up care among adult Ethiopian HIV-positive patients, especially in the Amhara region of the country, where almost one-third of the country’s ART is prescribed. The aim of this qualitative study was to collect such data from patients and healthcare providers in the Amhara region of Ethiopia. Methods Semi-structured interviews were conducted with 24 patients, of whom 11 had been lost to follow-up and were non-persistent with ART. In addition, focus group discussions were performed with 15 ART nurses and 19 case managers. All interviews and focus groups were audio-recorded, transcribed, and coded for themes and patterns in Amharic using a grounded theory approach. The emergent concepts and categories were translated into English. Results Economic constraints, perceived stigma and discrimination, fasting, holy water, medication side effects, and dissatisfaction with healthcare services were major reasons for patients being non-adherent and lost to follow-up. Disclosure of HIV status, social support, use of reminder aids, responsibility for raising children, improved health on ART, and receiving education and counseling emerged as facilitators of adherence to ART. Conclusions Improving adherence and retention requires integration of enhanced treatment access with improved job and food security. Healthcare providers need to be supported to better equip patients to cope with the issues associated with ART. Development of social policies and cooperation between various agencies are required to facilitate optimal adherence to ART, patient retention, and improved patient outcomes

Abstract Introduction: In 2016, Rwanda implemented “Treat All,” requiring the national HIV programme to increase antiretroviral (ART) treatment coverage to all people living with HIV. Approximately half of the 164,262 patients on ART have been on treatment for more than five years, and long-term retention of patients in care is an increasing concern. To address these challenges, the Ministry of Health has introduced a differentiated service delivery approach to reduce the frequency of clinical visits and medication dispensing for eligible patients. This article draws on key policy documents and the views of technical experts involved in policy development to describe the process of implementation of differentiated service delivery in Rwanda. Discussion: Implementation of differentiated service delivery followed a phased approach to ensure that all steps are clearly defined and agreed by all partners. Key steps included: definition of scope, including defining which patients were eligible for transition to the new model; definition of the key model components; preparation for patient enrolment; considerations for special patient groups; engagement of implementing partners; securing political and financial support; forecasting drug supply; revision, dissemination and implementation of ART guidelines; and monitoring and evaluation. Conclusions: Based on the outcomes of the evaluation of the new service delivery model, the Ministry of Health will review and strategically reduce costs to the national HIV program and to the patient by exploring and implementing adjustments to the service delivery model.

To find the clinical condition and motives for consultation of HIV + patients seen in our Health Centre. This was an observational and retrospective study. SITE. The study was carried out in the Primary Care context, in the Natahoyo Health Centre (Gijón). The clinical histories of 26 HIV + patients registered at the Health Centre were studied. These supposed a total of 387 consultations from the day they were diagnosed as seropositive to the 31 August, 1991, or until their death. The 387 consultations recorded broke down into a average of 14.8 consultations per patient (SD 12.7). 43% due to a request for detoxification. Only 5.5% of patients were referred to the second level. In line with the classifications of the W.H.O., 14 patients (56%) would be in stage I; 3 (12%) in stage II; 3 (12%) in stage III; and 5 (20%) in stage IV. HIV + patients often attend our Health Centre, but mainly for bureaucratic reasons. Consultations due to illness tend to be for minor pathologies, which are almost always treated successfully in the Centre itself. The WHO's classifications were found to be useful for assessing the stage of each HIV + patient at the Primary Care level.

As human immunodeficiency virus (HIV) treatment programs expand in Africa, delivery systems must be strengthened to support patient retention. Clinic characteristics may affect retention, but a relationship between clinic flow and attrition is not established. This project characterized HIV patient experience and flow in an urban Kenyan clinic to understand how these may affect retention. We used Toyota's lean manufacturing principles to guide data collection and analysis. Clinic flow was evaluated using value stream mapping and time and motion techniques. Clinic register data were analyzed. Two focus group discussions were held to characterize HIV patient experience. Results were shared with clinic staff. Wait times in the clinic were highly variable. We identified four main barriers to patient flow: inconsistent patient arrivals, inconsistent staffing, filing system defects, and serving patients out of order. Focus group participants explained how clinic operations affected their ability to engage in care. Clinic staff were eager to discuss the problems identified and identified numerous low-cost potential solutions. Lean manufacturing methodologies can guide efficiency interventions in low-resource healthcare settings. Using lean techniques, we identified bottlenecks to clinic flow and low-cost solutions to improve wait times. Improving flow may result in increased patient satisfaction and retention.

The prerequisite for an 'undetectable' HIV viral load has restricted access to transplantation for HIV-infected kidney recipients. However, HCV-infected recipients, owing to the historic limitations of HCV therapy in patients with renal disease, are commonly viremic at transplant and have universal access. To compare the effect of HIV, HCV, and HIV/HCV coinfection on kidney transplant patient and allograft outcomes, we performed a retrospective study of kidney recipients transplanted from January 1996 through December 2013. In multivariable analysis, patient (hazard ratio 0.90, 95% confidence interval 0.66-1.24) and allograft survival (0.60, 40-0.88) in 492 HIV patients did not differ significantly from the 117,791 patient-uninfected reference group. This was superior to outcomes in both the 5605 patient HCV group for death (1.44, 1.33-1.56) and graft loss (1.43, 1.31-1.56), as well as the 147 patient HIV/HCV coinfected group for death (2.26, 1.45-3.52) and graft loss (2.59, 1.60-4.19). HIV infection did not adversely affect recipient or allograft survival and was associated with superior outcomes compared with both HCV infection and HIV/HCV coinfection in this population. Thus, pretransplant viral eradication and/or immediate posttransplant eradication should be studied as potential strategies to improve posttransplant outcomes in HCV-infected kidney recipients.

Rational use of Rasayana therapy, in the management of HIV infected individuals, could potentially stabilize the destructive control mechanisms, by modulating the psycho-neuro-endocrine-immune axis. The objective of the present study has been to determine the short-term effects of Ranahamsa Rasayanaya (RR) in HIV infected patients. A total of 27 patients with documented HIV infection were randomly assigned to two groups, Group A – 5 g of RR twice daily with cow's milk and sugar. Group B – Only routine modern therapy was continued, if any they were taking, including highly active anti-retroviral therapy (HAART). Absolute CD4+ T-cell and total lymphocyte counts were measured in these patients, registered under Group A. Only 21 participants completed the study protocol (In Group A, 15 patients and in Group B, 6 patients). Initial mean CD4+ T-cell count was 304.50 ± 43.36 cells/microliter, which increased to 430.44 ± 66.01 cells/microliter by 41.36% (P<0.05), measured among 9 patients out of 15, who received RR in Group A. The RR seemed to be a safer adjuvant in people with HIV infection with respect to absolute CD4+ T-cell count over a 90 days treatment. PMID:22131710

A systematic review of the literature was conducted to find out what is known about patients' experiences of a dual diagnosis of HIV and cancer. We systematically searched the following databases; MEDLINE (Ovid Version); CINAHL Plus; PsycINFO and EMBASE from inception to June 2016 for studies that included patients with a dual diagnosis of cancer and HIV and focused on patient experiences. Studies with a focus on one illness rather than a dual diagnosis, those that focused on treatment strategies and medical management, epidemiology and pathology studies and comparison studies were all excluded. The full text of the included studies were reviewed. Information on location, sample size, study design and a narrative summary of findings were extracted using a standardised format. Studies were combined thematically. 1777 records were screened by title and abstract using the selection criteria described in the methods. Eight records were reviewed in depth in full text and seven selected as eligible. The selected studies suggest that a dual diagnosis of HIV and cancer has a powerful impact on individuals' behaviour. The experience of stigma was a consistent factor in all patient accounts and the strategy of selective disclosure to access support reveals how patient agency can interplay with stigma. This is an area largely unexplored in the published literature; further research into patients' experiences of a dual diagnosis of HIV and cancer will provide relevant knowledge in order to tailor and improve services.
The high mortality among HIV/tuberculosis (TB) coinfected patients in Eastern Europe is partly explained by the high prevalence of drug-resistant TB. It remains unclear whether outcomes of HIV/TB patients with rifampicin/isoniazid-susceptible TB in Eastern Europe differ from those in Western Europe or Latin America. One-year mortality of HIV-positive patients with rifampicin/isoniazid-susceptible TB in Eastern Europe, Western Europe, and Latin America was analysed and compared in a prospective observational cohort study. Factors associated with death were analysed using Cox regression modelsRESULTS:: Three hundred and forty-one patients were included (Eastern Europe 127, Western Europe 165, Latin America 49). Proportions of patients with disseminated TB (50, 58, 59%) and initiating rifampicin + isoniazid + pyrazinamide-based treatment (93, 94, 94%) were similar in Eastern Europe, Western Europe, and Latin America respectively, whereas receipt of antiretroviral therapy at baseline and after 12 months was lower in Eastern Europe (17, 39, 39%, and 69, 94, 89%). The 1-year probability of death was 16% (95% confidence interval 11-24%) in Eastern Europe, vs. 4% (2-9%) in Western Europe and 9% (3-21%) in Latin America; P < 0.0001. After adjustment for IDU, CD4 cell count and receipt of antiretroviral therapy, those residing in Eastern Europe were at nearly 3-fold increased risk of death compared with those in Western Europe/Latin America (aHR 2.79 (1.15-6.76); P = 0.023). Despite comparable use of recommended anti-TB treatment, mortality of patients with rifampicin/isoniazid-susceptible TB remained higher in Eastern Europe when compared with Western Europe/Latin America. The high mortality in Eastern Europe was only partially explained by IDU, use of ART and CD4 cell count. These results call for improvement of care for TB/HIV patients in Eastern Europe.

Human immunodeficiency virus (HIV), Hepatitis B virus (HBV) and Hepatitis C virus (HCV) share routes of transmission. There is limited data on the incidence of active co-infection with HBV and/or HCV in cancer patients infected with HIV in Africa. This was a prospective study based on 34 patients with varied cancer diagnosis, infected with HIV and awaiting cancer therapy in South Africa. HIV viral load, CD4+ cell counts, Alanine-aminotransferase and aspartate aminotransferase levels were tested. Exposure to HBV and HCV was assessed serologically using commercial kits. Active HBV and/or HCV co-infection was detected using viral specific nested PCR assays. HCV 5'-UTR PCR products were sequenced to confirm active HCV infection. Active viral infection was detected in 64.7% of patients for HBV, 38.2% for HCV, and 29.4% for both HBV and HCV. Occult HBV infection was observed in 63.6% of the patients, while seronegative HCV infection was found in 30.8% of patients. In addition, CD4+ cell count < 350 cells/µl was not a risk factor for increased active HBV, HCV or both HBV and HCV co-infections. A total of 72.7%, 18.2% and 9.1% of the HCV sequences were assigned genotype 5, 1 and 4 respectively.The study revealed for the first time a high active HBV and/or HCV co-infection rate in cancer patients infected with HIV. The findings call for HBV and HCV testing in such patients, and where feasible, appropriate antiviral treatment be indicated, as chemotherapy or radiotherapy has been associated with reactivation of viral hepatitis and termination of cancer therapy.

The purpose of the study was to find out the various personality factors among HIV/AIDS patients of injecting drug users. The study was conducted during the period of July 2001 to August 2004 at Manipur State, India in which 60 samples of both male and female in the age range of 21 to 35 years were taken through the helps from R.I.M.S Hospital, Imphal, J.N. Hospital, Imphal and several NGOs of Manipur. The patients were administered 16 PF (Personality profile developed by R.B. Cattell and H.W. Eber) test in which 16 personalities were detected. The profile of the respondents includes age and sex cases of HIV/ AIDS. In the sample among the HIV/AIDS patients, from the age group of 21 to 25 years consists of only 20%. Most of the patients are from 26 to 35 years consisting of two age groups, i.e., 26 to 30 years and 31 to 35 years having 40% each with total of 80%. In the survey, it has been found that majority of the HIV/AIDS patients is male which consists of 60% and remaining 40% belongs to female in the ratio of 60:40. The following four scales are used to explain personality profile: 1 Introversion vs extraversion. 2 Low anxiety vs high anxiety. 3 Emotional sensitivity vs tough poise. 4 Subdueness vs independence.

Atypical manifestations of Cryptococcus neoformans disease have been reported in patients with HIV-1 infection as part of the spectrum of the immune reconstitution inflammatory syndrome (IRIS). We describe a cryptococcal breast abscess in a patient presenting after 11 months of highly active antiretroviral therapy (HAART). The arguments for and against the case being a novel manifestation of IRIS are discussed. The potential hazards of using CD4 count as a surrogate marker of IRIS and the danger of misdiagnosing IRIS as failure of HAART are highlighted.

Successful treatment of HIV-associated multicentric Castleman disease (HIV+MCD) with rituximab-based approaches has dramatically improved survival and reduced the risk of human herpesvirus 8 (HHV8)-associated lymphoma. Longer term outcomes including relapse rates have not been described and are important to establish the potential role of maintenance therapy. A prospective cohort of 84 patients with biopsy-proven HIV+MCD were treated with risk-stratified rituximab-based therapy. Four patients (5%) died of refractory HIV+MCD and 80 achieved clinical remission. The median follow-up for the 80 patients was 6.9 years and their 5-year overall survival was 92% (95% confidence interval [CI], 85 to 99). Eighteen have relapsed (all histologically confirmed), including 5 with concomitant HHV8-associated lymphoma and MCD at relapse. The 5-year relapse-free survival is 82% (95% CI, 72 to 92). No clinical or laboratory findings that were present at MCD diagnosis predicted subsequent relapse, and the median time to first relapse was 30 months (maximum, 10 years). There were no significant differences in clinicopathological features at initial diagnosis and at relapse. All patients were successfully retreated at relapse with rituximab-based therapy. Only 1 patient died of relapsed MCD (at fifth relapse 9.4 years after initial diagnosis). Despite the use of rituximab, the risk of developing HHV8-associated lymphoma was significantly elevated in this cohort, with an incidence of 11.4/1000 person-years. The relatively low relapse rate and high salvage rates at relapse reduce the potential benefit of maintenance therapy; this should only be advocated in the context of a clinical trial. © 2017 by The American Society of Hematology.

We assessed the incidence and determinants of bacteremia, pneumonia, and sinusitis/otitis in HIV-positive people receiving cotrimoxazole (CTX) or dapsone-pyrimethamine (DP) for primary prophylaxis of Pneumocystis carinii pneumonia (PCP) and toxoplasmic encephalitis (TE) within a randomized clinical trial. In total, 244 patients were randomized: 122 were assigned to CTX and 122 to DP. In the cohort, 22 bacteremia, 63 pneumonia, and 39 sinusitis/otitis cases were observed. Incidence rates of bacteremia, pneumonia, and sinusitis/otitis as well as the 2-year probability of remaining free from any bacterial infection were not significantly different between the two groups. At multivariate analysis, the risks of developing bacteremia and pneumonia were found to be independently increased by the use of a central venous catheter (hazard ratio [HR], 4.48; p <.05 and HR, 4.13; p <.01, respectively) and by hospitalization (HR, 28.82; p <.05 and HR, 10.15; p <.05, respectively). In conclusion, CTX at the dosage employed for primary PCP/TE prophylaxis does not seem to protect against bacterial infections more than second-line DP.

The immune reconstitution inflammatory syndrome (IRIS) after starting antiretroviral treatment for HIV infection can be caused by a great variety of pathogens. Among these are non-tuberculous mycobacteria (NTM), with Mycobacterium avium complex being the most commonly described finding. Antimycobacterial treatment of NTM in cases of IRIS is controversial. We report the case of a 39-year-old man diagnosed with HIV-1 infection during admission to hospital with Pneumocystis jirovecii pneumonia (PCP) and a CD4 cell count of 60/μl. The patient started antiretroviral treatment and made an uneventful recovery from the PCP diagnosis, but was readmitted after 2.5 months with a purulent infrapatellar bursitis on the left knee. A surgical prodedure was performed and Mycobacterium malmoense was grown from the pus from the bursa. The patient recovered without supplemental antimycobacterial treament. To our knowledge, this is the first report on IRIS caused by M malmoense. PMID:23188870

To determine the risk factors and frequency of hepatitis B and C virus co-infections in human immunodeficiency virus-positive patients. The cross-sectional study was conducted at the Control of Diseases Centre of Kerman Medical University, southern Iran, between May and December 2011. Demographic features and history of high-risk behaviours were evaluated in 165 patients positive for human immunodeficiency virus. Third-generation hepatitis C virus antibody and hepatitis B surface antigen tests were performed by enzyme-linked immunosorbent assay method. SPSS 18 was used for statistical analysis. Out of the 165 patients, 136 (82.4%) were male and 29 (17.6%) were female. The mean age of the subjects was 40.4 +/- 9 years. Positive hepatitis C antibody was found in 122 (73.9%) and positive hepatitis B surface antigen was present in 6 (3.6%). Frequency of all three viruses co-infection was 3 (1.8%). History of imprisonment (OR = 17.5; 95% CI: 7.1-43.1) and drug injection addiction (OR = 15.3; 95% CI: 6.4-36.1) were the most significant risk factors involved in hepatitis C virus co-infection. Seroprevalence of hepatitis C virus and human immunodeficiency virus co-infection was high and it was strongly related to history of imprisonment and drug injection addiction.

Objective To identify risk factors for loss to follow up (LTFU) in an HIV-infected pediatric population in Dar es Salaam, Tanzania between 2004 and 2011. Design Longitudinal analysis of 6236 HIV-infected children. Methods We conducted a prospective cohort study of 6236 pediatric patients enrolled in care and treatment in Dar es Salaam from October 2004 to September 2011. LTFU was defined as missing a clinic visit for >90 days for patients on ART and for >180 days for patients in care and monitoring. The relationship of baseline and time-varying characteristics to risk of LTFU was examined using a Cox proportional hazards model. Results 2130 children (34%) were LTFU over a median follow up of 16.7 months (IQR, 3.4–36.9). Factors independently associated with a higher risk of LTFU were age 2 years (RR=1.59, 95% CI 1.40–1.80), diarrhea at enrollment (RR=1.20, 95% CI 1.03–1.41), a low mid-upper arm circumference for age (RR=1.20, CI 1.05–1.37), eating protein 3 times a week (RR=1.39, 95% CI 1.05–1.90), taking cotrimoxazole (RR=1.39, 95% CI 1.06–1.81), initiating onto antiretrovirals (RR=1.37, 95% CI 1.17–1.61), receiving treatment at a hospital instead of a local facility (RR=1.39, 95% CI 1.06–1.41), and starting treatment in 2006 or later (RR=1.10, 95% CI 1.04–1.16). Conclusions Health workers should be aware of pediatric patients who are at greatest risk of LTFU, such as younger and undernourished patients, so that they can proactively counsel families about the importance of visit adherence. Findings support decentralization of HIV care to local facilities as opposed to hospitals. PMID:26247894

The authors describe a clinical case of an HIV+, HBV+ and HCV+ 46-year-old male patient, with a history of drug abuse of intravenous heroin, admitted to their attention for high remittent fever (39 C), weight loss and severe dysphonia. The increasing severity of dysphonia had required a fiberlaryngoscopic examination which allowed a diagnosis of hypertrophy of vocal chords. The Wright-Giemsa stain performed on vocal chord biopsy evidenced Leishmania infantum. The same protozoon was subsequently also revealed in bone marrow aspirate. The patient underwent a course of therapy with Amphotericin B deoxycolate (0.5 mg/kg) which had to be interrupted due to insurgence of diffuse petechiae and switched to Amphotericin in cholesterinic suspension (2.5 mg/kg every 21 days). After three months, insurgence of high fever related to the infusion induced the start of therapy with liposomal Amphotericin B (3 mg/kg every 28 days) which led in 4 weeks to a complete clinical remission. Prophylaxis with liposomal Amphotericin B is continuing and remission has persisted for 40 months. This case report shows the importance of liposomal Amphotericin B therapy in order either to obtain clinical remission of visceral leishmaniasis or, in secondary prophylaxis, to reduce the risk of the disease's recurrence.

Isolated hepatic tuberculosis presenting as a mass either with or without fever can be confused with hepatocellular carcinoma. Clinical examination and laboratory investigations are not specific. Radiological investigations such as ultrasound and computed tomography cannot confirm the diagnosis; hence it is vital to always make an effort to demonstrate presence of acid fast bacilli in aspirated pus or necrotic material from a liver mass. We present a case of 50 years old male patient with HIV/AIDS who presented with non-specific symptoms without fever, clinically with hepatomegaly mimicking hepatocellular carcinoma with metastasis. Abdominal ultrasound revealed a mass in the left liver lobe, with diffuse involvement in the right liver lobe. Liver mass histology showed granulomatous pattern with epitheloid cell aggregation. Aspirated blood from fine-needle guided biopsy stained on Ziehl Neelsen for acid fast bacilli turned out positive. Clinical examination did not reveal lymphadenopathy, abdominal ultrasound also ruled out para-aortic lymphadenopathy, and chest x-ray was essentially normal. Evaluation of the patient six months after completing quadruple treatment for tuberculosis showed marked clinical improvement. The objective of this case report is to highlight the importance of considering hepatic tuberculosis as a differential diagnosis in cases of hepatomegaly and initiate appropriate investigations to rule out a possibility of Tuberculosis which is potentially treatable with early diagnosis.

Lichenoid drug reactions to vaccinations are rare but well-documented events. The vast majority of these reported reactions have been triggered by Hepatitis B vaccination (HBV). We describe an impressive generalized lichenoid drug reaction following the influenza vaccination. A 46-year-old African-American woman with a history of treated human immunodeficiency virus (HIV) disease developed a diffuse, pruritic rash one day following vaccination against the influenza virus. Physical exam and histopathology were consistent with a lichenoid drug eruption. This is only the fifth reported case of lichenoid drug reaction, and only the second generalized case, following influenza vaccination. The patient's underlying HIV disease, known to be a risk factor for both cutaneous drug reactions and more severe manifestations of lichen planus, likely predisposed her to this generalized hypersensitivity phenomenon.

We estimate how the effect of antiretroviral treatment depends on the time from HIV-infection to initiation of treatment, using observational data. A major challenge in making inferences from such observational data arises from biases associated with the nonrandom assignment of treatment, for example bias induced by dependence of time of initiation on disease status. To address this concern, we develop a new class of Structural Nested Mean Models (SNMMs) to estimate the impact of time of initiation of treatment after infection on an outcome measured a fixed duration after initiation, compared to the effect of not initiating treatment. This leads to a SNMM that models the effect of multiple dosages of treatment on a time-dependent outcome, in contrast to most existing SNNMs, which focus on the effect of one dosage of treatment on an outcome measured at the end of the study. Our identifying assumption is that there are no unmeasured confounders. We illustrate our methods using the observational Acute Infection and Early Disease Research Program (AIEDRP) Core01 database on HIV. The current standard of care in HIV-infected patients is Highly Active Anti-Retroviral Treatment (HAART); however, the optimal time to start HAART has not yet been identified. The new class of SNNMs allows estimation of the dependence of the effect of 1 year of HAART on the time between estimated date of infection and treatment initiation, and on patient characteristics. Results of fitting this model imply that early use of HAART substantially improves immune reconstitution in the early and acute phase of HIV-infection. © 2012, The International Biometric Society.

Identification of educational needs of natural helpers for the home-based care of persons living with HIV or AIDS. Surin, Thailand. The very significant increase in the number of persons living with aids in Thailand, (1995: 20,154 notified cases; 1996: 23,309 cases; 1997: 25,064 cases), and the insufficiency of medical care for patients within Thailand's health structures, have driven Médecins Sans Frontières (MSF) to put in place since 1996 a home-based care project in Surin province (North-Eastern Thailand). In Thai culture, the sick are commonly cared for by one family member, known as the natural helper. An evaluation of the health situation showed that natural helpers who took care of a family member living with HIV or aids were not prepared for this situation. In order to better define the tasks that they ought to perform, we carried out a needs assessment in three interdependent steps: a records analysis of the activities delegated to natural helpers by nurses; an enquiry on the acceptability of natural helpers to carry out these cares and on the perceived usefulness of being trained; an expert consensus on the cares to be carried out by the natural helpers, obtained by the Delphi method. Twenty seven cares were identified as being able to be provided by natural helpers. They constitute as a list of reference for the training for natural helpers. This work has shown a social coherence between the different actors of the project. At no stage was the role of the natural helpers questioned. On the contrary, natural helpers have a privileged place within the family and in the home-based care programme. Natural helpers will allow continuity of care between the health structures and the patient's home.

Hyperbilirubinemia is common among patients exposed to atazanavir (ATV), but its long-term significance is not well documented. The objective was to analyze hyperbilirubinemia (incidence, regression, determinants, and outcome) among 1150 HIV-positive patients followed-up in a prospective cohort between 2003 and 2012. Cumulative incidence of hyperbilirubinemia grades 3-4 and its probability of regression were estimated using Kaplan-Meier method. Cox proportional hazards model was used to study the determinants. Generalized estimating equation (GEE) regression was used to evaluate the association between hyperbilirubinemia grades 3-4 and adverse health outcome. Eight years cumulative incidence of hyperbilirubinemia was 83.6% (95% CI:79.0-87.7) and 6.6% (95% CI:4.7-9.2) among ATV users and non-users, respectively. This clinical outcome fluctuated considerably, as most patients exposed to ATV (91%) regressed, transiently, to lower grade at some point during follow-up. Determinants were atazanavir (HR=147.90, 95% CI: 33.64-604.18), ritonavir (HR=5.18, 95% CI:2.33-11.48), zidovudine (HR=2.62, 95% CI:1.07-6.46), and age (HR=1.04 95% CI:1.01-1.08). Alcohol consumption and others non-antiretroviral medications including hepatotoxic and recreational drugs were not available for analyses. Incidence of hyperbilirubinemia was very high among ATV users and, although regression to lower grade was frequent in the clinical follow-up of these patients, this was usually transient as the mean level of bilirubin stayed at a relatively high level. Importantly, long-term hyperbilirubinemia was not associated with adverse health outcome.

Use of complementary and alternative medicine (CAM) is common among Latinos living with HIV in the United States (U.S.)-Mexico border region. Health providers may vary in their approach to communicating acceptance or non acceptance of CAM use, which can undermine patient confidence in disclosing CAM use. Patient-provider communication about CAM is important because certain types of CAM can affect antiretroviral therapy (ART) adherence. We undertook the present binational study to understand U.S. and Mexican provider beliefs, and perceptions surrounding CAM use among Latino patients, and to learn if and how CAM communication occurs. Between July and December 2010, we conducted in-depth, qualitative interviews in Tijuana and San Diego. Analysis procedures drew upon principles of Grounded Theory. The sample was comprised of 19 HIV-health care providers, including 7 women and 12 men. Emerging CAM-related themes were: Provider's perceptions, attitudes and knowledge about CAM; CAM types and modalities; and patient-provider CAM communication. Many clinicians were uncomfortable supporting CAM use with their patients. San Diego providers reported more frequent instances of CAM use among Latino patients than Tijuana providers. Providers from both cities reported that patients infrequently disclose CAM use and almost half do not routinely ask patients about CAM practices. Most of the providers acknowledged that they lack information about CAM, and are concerned about the drug interaction as well as the effects of CAM on adherence. Our findings have important implications for understanding provider communication surrounding CAM use in a highly transnational population and context. Because CAM use may undermine ART adherence and is highly prevalent among Latinos, provider communication about CAM is critical to improved health outcomes among HIV-positive Latinos. Considering the significant growth of U.S. Latinos, especially in the U.S.-Mexico border region, assessment of

The vast majority of people living with HIV/AIDS reside in low and middle income countries, particularly in Sub-Saharan Africa, including Ethiopia. Despite the huge number of service users in the local area, cognitive disorder among HIV patients has not been extensively studied and there is a dearth of knowledge on the subject. The objective of this study was to assess the prevalence and associated factors of HIV-associated neurocognitive disorder among people living with HIV/AIDS in antiretroviral therapy (ART) clinics. Institution based cross sectional study was conducted from April to May, 2015 at Dessie Referral Hospital & Kombolcha Health Center. International HIV Dementia Scale was used to screen HIV associated neurocognitive deficits. Logistic regression analysis was used to assess predictors of neurocognitive disorders. The risk of HIV associated neurocognitive disorder was 36.4%. Those who had CD4 count of 500 cells/dl or less (AOR = 2.368 (1.524, 3.680)), no formal education (AOR = 4.287 (2.619, 7.016)), poor medication adherence (AOR = 1.487 (1.010, 2.180)) and older age (AOR = 3.309 (1.259, 8.701)) were found to be significantly associated with HIV associated neurocognitive disorders. The risk of HIV-associated neurocognitive disorder was found to be high among people living with HIV/AIDS. This emphasizes the need of regular cognitive screening for early identification and appropriate intervention. Copyright © 2016 Elsevier Ltd. All rights reserved.

During HIV infection, a down-modulation of CD3ζ was found on T cells, contributing to T-cell anergy. In this work, we studied the correlation between myeloid-derived suppressor cells (MDSC) frequency and T-cell CD3ζ expression. Moreover, we investigated the mechanisms of CD3ζ decrease exploited by MDSC. CD3ζ expression and MDSC frequency were evaluated by flow cytometry on peripheral blood mononuclear cells from 105 HIV-positive (HIV+) patients. The role of MDSC in the modulation of the HIV-specific T-cell response was evaluated. The level of CD3ζ mRNA and ELF-1 protein were analysed by real-time-PCR and western blot, respectively. We found that granulocytic-MDSC (Gr-MDSC) were expanded in HIV+ patients compared with healthy donors; in particular, in cART-treated individuals a higher Gr-MDSC frequency was observed in patients with a CD4 T-cell count below 400 cells/μl. We found an inverse correlation between the percentage of Gr-MDSC and CD3ζ level. Moreover, in-vitro MDSC depletion induced the up-regulation of CD3ζ in T cells, restoring the functionality of αβ, but not γδ T cells. The in-vitro effect of isolated MDSC on CD3ζ expression was found cell contact-dependent, and was not mediated by previously described molecules. CD3ζ down-modulation corresponds to the decrease of its mRNA induced by silencing the transcription factor ELF-1. Our data provide new knowledge on mechanisms used by Gr-MDSC in immune-modulation and on their role in the immune reconstitution during antiviral treatments.

When an HIV-positive woman becomes pregnant, additional nutritional considerations are warranted. Compared to routine prenatal nutritional assessment and intervention, pregnant HIV-positive women have increased needs to promote a healthy outcome. This column contains information on HIV and pregnancy, nutrition and infection, and nutrition for HIV-positive pregnancy. This content can be integrated into childbirth education settings to improve care to women who are HIV-positive. PMID:17273329

Longitudinal data are widely analysed using linear mixed models, with 'random slopes' models particularly common. However, when modelling, for example, longitudinal pre-treatment CD4 cell counts in HIV-positive patients, the incorporation of non-stationary stochastic processes such as Brownian motion has been shown to lead to a more biologically plausible model and a substantial improvement in model fit. In this article, we propose two further extensions. Firstly, we propose the addition of a fractional Brownian motion component, and secondly, we generalise the model to follow a multivariate-t distribution. These extensions are biologically plausible, and each demonstrated substantially improved fit on application to example data from the Concerted Action on SeroConversion to AIDS and Death in Europe study. We also propose novel procedures for residual diagnostic plots that allow such models to be assessed. Cohorts of patients were simulated from the previously reported and newly developed models in order to evaluate differences in predictions made for the timing of treatment initiation under different clinical management strategies. A further simulation study was performed to demonstrate the substantial biases in parameter estimates of the mean slope of CD4 decline with time that can occur when random slopes models are applied in the presence of censoring because of treatment initiation, with the degree of bias found to depend strongly on the treatment initiation rule applied. Our findings indicate that researchers should consider more complex and flexible models for the analysis of longitudinal biomarker data, particularly when there are substantial missing data, and that the parameter estimates from random slopes models must be interpreted with caution.

Background Antiretroviral therapy scale-up in Sub-Saharan Africa has created a growing, aging HIV-positive population at risk for non-communicable diseases such as hypertension. However, the prevalence and risk factors for hypertension in this population remain incompletely understood. Methods We measured blood pressure and collected demographic data on over 65,000 adults attending multi-disease community health campaigns in 20 rural Ugandan communities (SEARCH Study: NCT01864603). Our objectives were to determine (i) whether HIV is an independent risk factor for hypertension, and (ii) awareness and control of hypertension in HIV-positive adults and the overall population. Results Hypertension prevalence was 14% overall, and 11% among HIV-positive individuals. 79% of patients were previously undiagnosed, 85% were not taking medication, and 50% of patients on medication had uncontrolled blood pressure. Multivariate predictors of hypertension included older age, male gender, higher BMI, lack of education, alcohol use, and residence in Eastern Uganda. HIV-negative status was independently associated with higher odds of hypertension (OR 1.2, 95% CI: 1.1–1.4). Viral suppression of HIV did not significantly predict hypertension among HIV-positives. Significance The burden of hypertension is substantial and inadequately controlled, both in HIV-positive persons and overall. Universal HIV screening programs could provide counseling, testing, and treatment for hypertension in Sub-Saharan Africa. PMID:27232186

A nuanced understanding of HIV-positive status disclosure is urgently needed to inform the implementation of prevention interventions, including TasP and PrEP. To provide such understanding for the high HIV-burden setting of rural KwaZulu-Natal, we conducted a prospective cohort study to characterize determinants and trends in HIV-positive status disclosure. 687 consenting HIV-positive individuals (73.2% female; 60.3% ART initiated) were enrolled. Reports of any incidence of disclosure to either a family member or sexual partner at enrollment and follow-up visits (median 4.4 months post-enrolment) were common (91.0%); however, reports of disclosure specifically to sexual partners were relatively rare (34.1%), especially in women (29.8%). Participants not engaged in a stable partnerships, not ART-imitated, and/or who had disclosed to their family were at risk of non-disclosure to sexual partners. These data highlight both an urgent need to empower HIV-positive individuals, and the significant barriers to targeting sero-discordant couples for HIV prevention in this setting. PMID:25677128

Facial lipoatrophy is a frequently reported condition associated with use of antiretroviral (ARV) drugs. Poly-L-lactic acid (PLLA) acid has been used to correct facial lipoatrophy in people with HIV since 2004 both in Europe and the United States. The objective of this study was to establish, in real life conditions and in a large sample, the safety of PLLA (New Fill®, Valeant US, Sinclair Pharma Paris, France) to correct facial lipoatrophy among HIV-positive patients. A longitudinal study was conducted between 2005 and 2008 in France. Data from 4,112 treatment courses (n = 4,112 patients) and 15,665 injections sessions (1 to 5 injection sessions per treatment course) were gathered by 200 physicians trained in the use of PLLA. The average age of patients (88.3% males) treated for lipoatrophy was 47.1 ± 8.1 years (Mean ± SD); 91.2% of patients had been receiving ARV treatment for 10.9 (±4.2) years; CD4 T-cell count was 535 ± 266 cells/mm3. The duration of facial lipoatrophy was 5 ± 2.8 years and the severity was such that 47.3% of patients required five injection sessions of PLLA and 81.9% of the sessions required two vials of the preparation. The final visit, scheduled two months after the last injection session, was attended by 66.0% of patients (n = 2,713). 48 treatment courses (2.8%) were discontinued due to adverse events (AEs). The overall incidence of AEs per course was 18.8%. Immediate AEs, bleeding (3.4%), bruising (2.3%), pain (2.0%), redness at injection site (1.6%), and swelling of the face (0.7%), occurred in 15.4% of courses and 7.0% of sessions (usually during the first session). Non-immediate AEs, mainly nodules (5.7%), inflammation (0.7%), granuloma (0.3%), discolouration (0.2%), and skin hypertrophy (0.1%), occurred in 6.7% of courses. Non-immediate AEs occurred within a time ranging from 21 days (inflammation) to 101 days (granuloma) and all but three of the 13 cases of granuloma resolved. Product efficacy was

Introduction Several studies from resource-limited settings have demonstrated that clinical and immunologic criteria are poor predictors of virologic failure, confirming the need for viral load monitoring or at least an algorithm to target viral load testing. We used data from an electronic patient management system to develop an algorithm to identify patients at risk of viral failure using a combination of accessible and inexpensive markers. Methods We analyzed data from HIV-positive adults initiated on antiretroviral therapy (ART) in Johannesburg, South Africa, between April 2004 and February 2010. Viral failure was defined as ≥2 consecutive HIV-RNA viral loads >400 copies/ml following suppression ≤400 copies/ml. We used Cox-proportional hazards models to calculate hazard ratios (HR) and 95% confidence intervals (CI). Weights for each predictor associated with virologic failure were created as the sum of the natural logarithm of the adjusted HR and dichotomized with the optimal cut-off at the point with the highest sensitivity and specificity (i.e. ≤4 vs. >4). We assessed the diagnostic accuracy of predictor scores cut-offs, with and without CD4 criteria (CD4 <100 cells/mm3; CD4 < baseline; >30% drop in CD4), by calculating the proportion with the outcome and the observed sensitivity, specificity, positive and negative predictive value of the predictor score compared to the gold standard of virologic failure. Results We matched 919 patients with virologic failure (1:3) to 2756 patients without. Our predictor score included variables at ART initiation (i.e. gender, age, CD4 count <100 cells/mm3, WHO stage III/IV and albumin) and laboratory and clinical follow-up data (drop in haemoglobin, mean cell volume (MCV) <100 fl, CD4 count <200 cells/mm3, new or recurrent WHO stage III/IV condition, diagnosis of new condition or symptom and regimen change). Overall, 51.4% had a score 51.4% had a score ≥4 and 48.6% had a score <4. A predictor score including CD4

A variety of exfoliative cheilitis has been observed in reactive HIV-1 patients subjected to high activity antiretroviral therapy (HAART). The lesions exhibit exfoliation, crater formation, fissuring, erosions and/or the formation of papules, vesicles and blisters associated to erythema and edema. The condition is not included in the 1993 EEC Clearinghouse classification (1) of oral lesions associated with HIV infection. In an earlier series of 1899 patients (2), we failed to observe this pathology and have only found one similar case described in the literature to date (3). We present a series of 6 patients with HIV infection and morpho-histological alterations of the labial semimucosa, subjected to HAART. The 6 patients were selected from among 20 HIV-positive individuals treated in our Infectious Diseases Unit with a combination of nucleoside and non-nucleoside reverse transcriptase inhibitors and protease inhibitors requiring stomatological care for painful lesions of the lips and oral cavity. The study was conducted over a 6-month period between May and October 1998. An analysis was made of the case histories, CD4-positive cell counts and viral load. The stomatological explorations were completed with biopsies, hematoxylin-eosin staining and immunohistochemical studies involving AE1 and AE3 monoclonal antibodies, vimentin, protein S-100, carcinoembryonic antigen (CEA), laminin, CD8, HLA-DR, BM-1 and CD31 markers. At the time of detection of the oral lesions, the patients had received different combinations of the following antiretroviral treatments: stavudine (D4T), zalcitabine (DDC), didanosine (DDI), zidovudine (AZT), lamivudine (3TC), nelfinavir (NFV), saquinavir (SQV), ritonavir (RTV), hydroxyurea (HU), indinavir (IDN) and efavirenz (EFV). There were four males and two females (age range 31-42 years). The CD4-positive and viral load ranges were 70-330 cells/mm3 and 200-500,200 copies, respectively. Stomatologic manifestations: The oral clinical

BACKGROUND: HIV-associated psoriasis is well-documented. Genetic, cellular, and cytokine profiles have been used as evidence to suggest psoriasis activates antiviral pathways. There has been a lack of epidemiologic evidence investigating whether psoriasis patients have lower HIV viral counts compared to non-psoriasis patients.
OBJECTIVE: Compare the viral load set point of HIV positive patients with and without psoriasis.
METHODS: A retrospective matched cohort study of HIV positive patients with and without psoriasis using the Kaiser Permanente Southern California Health Plan database.
RESULTS: We identified 101 HIV-positive psoriasis cases; 19 met inclusion criteria and were matched with 3-5 control patients; 94 total patients were analyzed. The mean age was 41.4 (12.07) years and 83% were male. Overall, the median log of the viral load of cases was slightly higher than controls (4.3 vs 4.2; P less than 0.01).
CONCLUSIONS: The serum viral load set point of patients with HIV and psoriasis was slightly higher than the viral load set point of HIV patients without psoriasis.

Research on pregnancy termination largely assumes HIV status is the only reason why HIV-positive women contemplate abortion. As antiretroviral treatment (ART) becomes increasingly available and women are living longer, healthier lives, the time has come to consider the influence of other factors on HIV-positive women's reproductive decision-making. Because ART has been free and universally available to Brazilians for more than two decades, Brazil provides a unique context in which to explore these issues. A total of 25 semi-structured interviews exploring women's pregnancy termination decision-making were conducted with women receiving care at the Reference Centre for HIV/AIDS in Salvador, Brazil. Interviews were transcribed, translated into English and coded for analysis. HIV played different roles in women's decision-making. In all, 13 HIV-positive women did not consider terminating their pregnancy. Influential factors described by those who did consider terminating their pregnancy included fear of HIV transmission, fear of HIV-related stigma, family size, economic constraints, partner and provider influence, as well as lack of access to pregnancy termination services and abortifacients. For some HIV-positive women in Brazil, HIV can be the only reason to consider terminating a pregnancy, but other factors are significant. A thorough understanding of all variables affecting reproductive decision-making is necessary for enhancing services and policies and better meeting the needs and rights of HIV-positive women.

To compare causes of death (CoDs) from two independent sources: National Basic Death File (NBDF) and deaths reported to the Spanish HIV Research cohort [Cohort de adultos con infección por VIH de la Red de Investigación en SIDA CoRIS)] and compare the two coding algorithms: International Classification of Diseases, 10th revision (ICD-10) and revised version of Coding Causes of Death in HIV (revised CoDe). Between 2004 and 2008, CoDs were obtained from the cohort records (free text, multiple causes) and also from NBDF (ICD-10). CoDs from CoRIS were coded according to ICD-10 and revised CoDe by a panel. Deaths were compared by 13 disease groups: HIV/AIDS, liver diseases, malignancies, infections, cardiovascular, blood disorders, pulmonary, central nervous system, drug use, external, suicide, other causes and ill defined. There were 160 deaths. Concordance for the 13 groups was observed in 111 (69%) cases for the two sources and in 115 (72%) cases for the two coding algorithms. According to revised CoDe, the commonest CoDs were HIV/AIDS (53%), non-AIDS malignancies (11%) and liver related (9%), these percentages were similar, 57, 10 and 8%, respectively, for NBDF (coded as ICD-10). When using ICD-10 to code deaths in CoRIS, wherein HIV infection was known in everyone, the proportion of non-AIDS malignancies was 13%, liver-related accounted for 3%, while HIV/AIDS reached 70% due to liver-related, infections and ill-defined causes being coded as HIV/AIDS. There is substantial variation in CoDs in HIV-infected persons according to sources and algorithms. ICD-10 in patients known to be HIV-positive overestimates HIV/AIDS-related deaths at the expense of underestimating liver-related diseases, infections and ill defined causes. CoDe seems as the best option for cohort studies.

Introduction The cases of cryptococcal meningitis and other forms of cryptococcosis have increased in recent time and the present scenario of the condition with significant morbidity and mortality is actually posing a serious threat to the community, so an early and prompt diagnosis is necessary to prevent serious complications and thus improving the overall disease outcome. Aim Comparison of diagnostic efficacy of nested Polymerase Chain Reaction (PCR) with Latex Agglutination Test (LAT) in the Cerebro Spinal Fluid (CSF) samples of the cases of meningitis in HIV positive and negative cases. Materials and Methods We have compared the diagnostic efficacy of Latex Agglutination Test (LAT) with nested Polymerase Chain Reaction (PCR) in 200 Cerebrospinal Fluid (CSF) samples, including 14 HIV positive also, in the cases of suspected cryptococcal meningitis. Nested PCR was done in all cases reporting positive by LAT and results were then compared with that of India ink and culture on Sabouraud Dextrose Agar (SDA), and the isolates were further identified by urease, nitrate and sugar assimilation tests. Results Of the 200 cases, including 14 HIV positive, LAT was positive in 46 cases while 154 were negative. Out of these 46 LAT positive cases, nested PCR was positive in 40 cases only, while culture and India ink was positive in 38 and 33 cases respectively. Majority of the cases, 30 (65.2%) were between age group 21-50 years, while 2 (4.3%) in 0-20, and 14 (30.4%) in 51-80 years age group. Conclusion Although negative staining like India ink and nigrosin are most widely used techniques, but these suffer with subjective error. Rapid method like LAT is available but it always has the scope of false positive and negative results. In such cases nested PCR can help in establishing final diagnosis. PMID:27190801

SUMMARY HIV-positive persons and the elderly have increased risk for influenza-related complications, including pneumonia. Using claims data for pneumonia and influenza (P&I) hospitalization in the USA, we described the temporo-demographic trends and in-patient case-fatality in persons aged ⩾65 years by HIV status. Our results showed a near doubling in the fraction of P&I admissions representing HIV-positive persons between 1991 and 2004 [relative risk (RR) 1·95, 95% confidence interval (CI) 1·80–2·13]. HIV-positive adults were younger (70·3 vs. 79·9 years, P<0·001), and had higher case-fatality (18·0% vs. 12·6%, P<0·001). Adjusting for other variables, case-fatality decreased by 5·8% in HIV-positive persons with the availability of highly active antiretroviral therapy (P=0·032). However, HIV-positive seniors were still 51% more likely to die during hospitalization than HIV-negative persons in 2004 (OR 1·51, 95% CI 1·23–1·85). HIV-infected persons represent a growing fraction of the elderly population hospitalized with P&I. Additional measures are needed to reduce case-fatality associated with P&I in this population.

A case of an HIV-positive young drug addict presenting with fever, respiratory distress, and pulmonary infiltrates is reported. Pulmonary talcosis was diagnosed by transbronchial biopsy. The differential diagnosis of pulmonary infiltrates in HIV-positive patients is reviewed and the predisposition of drug addicts to develop both HIV infection, as well as pulmonary talcosis, is discussed. Pulmonary talcosis must be considered in the differential diagnosis of pulmonary infiltrates of HIV-positive drug addicts.

Though the risk of HIV transmission in sports is slight, physicians who treat active patients can encounter weighty legal issues. Mandatory testing, exclusion of HIV-positive athletes, and breaching of patient confidentiality can lead to lawsuits. Knowing the possible consequences can help physicians in setting effective, legal prevention…

In many settings worldwide, HIV-positive individuals have experienced a significant level of stigma and discrimination. This discrimination may also impact other family members affected by the disease, including children. The aim of our study was to identify factors associated with stigma and/or discrimination among HIV-affected youth and their HIV-positive caregivers in central Haiti. Recruitment of HIV-positive patients with children aged 10-17 years was conducted in 2006-2007. Data on HIV-related stigma and/or discrimination were based on interviews with 451 youth and 292 caregivers. Thirty-two percent of caregivers reported that children were discriminated against because of HIV/AIDS. Commune of residence was associated with discrimination against children affected by HIV/AIDS and HIV-related stigma among HIV-positive caregivers, suggesting variability across communities. Multivariable regression models showed that lacking social support, being an orphan, and caregiver HIV-related stigma were associated with discrimination in HIV-affected children. Caregiver HIV-related stigma demonstrated a strong association with depressive symptoms. The results could inform strategies for potential interventions to reduce HIV-related stigma and discrimination. These may include increasing social and caregiver support of children affected by HIV, enhancing support of caregivers to reduce burden of depressive symptoms, and promoting reduction of HIV-related stigma and discrimination at the community-level.

Objectives Two nucleos(t)ide reverse-transcriptase inhibitors (NRTIs) plus 1 non-NRTI (nNRTI) remain the preferred or alternative combination antiretroviral therapy (cART) for antiretroviral-naive HIV-positive patients in Taiwan. The three most commonly used nNRTIs are nevirapine (NVP), efavirenz (EFV) and rilpivirine (RPV). This study aimed to determine the incidences of hepatotoxicity and skin rashes within 4 weeks of initiation of cART containing 1 nNRTI plus 2 NRTIs. Methods Between June, 2012 and November, 2015, all antiretroviral-naive HIV-positive adult patients initiating nNRTI-containing cART at 8 designated hospitals for HIV care were included in this retrospective observational study. According to the national HIV treatment guidelines, patients were assessed at baseline, 2 and 4 weeks of cART initiation, and subsequently every 8 to 12 weeks. Plasma HIV RNA load, CD4 cell count and aminotransferases were determined. The toxicity grading scale of the Division of AIDS (DAIDS) 2014 was used for reporting clinical and laboratory adverse events. Results During the 3.5-year study period, 2,341 patients initiated nNRTI-containing cART: NVP in 629 patients, EFV 1,363 patients, and RPV 349 patients. Rash of any grade occurred in 14.1% (n = 331) of the patients. In multiple logistic regression analysis, baseline CD4 cell counts (per 100-cell/μl increase, adjusted odds ratio [AOR], 1.125; 95% confidence interval [95% CI], 1.031–1.228) and use of NVP (AOR, 2.443; 95% CI, 1.816–3.286) (compared with efavirenz) were independently associated with the development of skin rashes. Among the 1,455 patients (62.2%) with aminotransferase data both at baseline and week 4, 72 (4.9%) developed grade 2 or greater hepatotoxicity. In multiple logistic regression analysis, presence of antibody for hepatitis C virus (HCV) (AOR, 2.865; 95% CI, 1.439–5.704) or hepatitis B surface antigen (AOR, 2.397; 95% CI, 1.150–4.997), and development of skin rashes (AOR, 2.811; 95% CI, 1

A recent study showed that implant-prosthetic rehabilitation in well-controlled HIV patients gave slightly worse results than in an healthy population, and failures were all linked to infection. The aim of this study was to examine the associations between the success of implant-prosthetic treatment and systemic CD4+ level, smoking habits, and oral hygiene. This mono-centric study included HIV patients with a stable disease and good oral hygiene requiring implant rehabilitation. Each patient received at least one dental implant. Prosthesis were delivered after 90 days in the upper jaw and 60 days in the lower jaw. Primary outcome measures were prosthetic failures, implant failures, peri-implant marginal bone level changes, and biological complications (peri-implantitis, pus, pain, paresthesia). The possible association with CD4 count, smoking habits, and oral hygiene was analyzed. Sixty-eight patients received 194 implants, and 66 patients (190 implants) were followed for 1 year. No significant associations were found between CD4+ count, oral hygiene-associated variables, and any of the outcome measures. If compared with nonsmoking/light smoking patients, patients who smoked >10 cigarettes/day suffered a statistically significant greater number of implant failures (p ≤ .005), presented a comparatively higher number of peri-implantitis (p < .001), as well as a higher frequency of pus (p ≤ .007), and reported pain (p ≤ .009). Within the limitation of the present study, placement of dental implants in HIV-positive patients with stable disease seems a reasonable treatment option, regardless of CD4+ cell count, provided that they are in a normal range. Oral hygiene variables were not influent in this group of patient following recall appointments, while HIV-positive heavy smokers (>10 cigarettes/day) demonstrated an increased risk of early implant failure, peri-implantitis, episodes of pus, and self-reported pain. © 2015 Wiley Periodicals, Inc.

Even with optimal antiretroviral therapy, human immunodeficiency virus (HIV) persists in plasma, blood cells, and tissues. To develop new therapies, it is essential to know what cell types harbor residual HIV. We measured levels of HIV DNA, RNA, and RNA/DNA ratios in sorted subsets of CD4+ T cells (CCR7+, transitional memory, and effector memory) and non-CD4+ T leukocytes from blood, ileum, and rectum of 8 ART-suppressed HIV-positive subjects. Levels of HIV DNA/million cells in CCR7+ and effector memory cells were higher in the ileum than blood. When normalized by cell frequencies, most HIV DNA and RNA in the blood were found in CCR7+ cells, whereas in both gut sites, most HIV DNA and RNA were found in effector memory cells. HIV DNA and RNA were observed in non-CD4+ T leukocytes at low levels, particularly in gut tissues. Compared to the blood, the ileum had higher levels of HIV DNA and RNA in both CD4+ T cells and non-CD4+ T leukocytes, whereas the rectum had higher HIV DNA levels in both cell types but lower RNA levels in CD4+ T cells. Future studies should determine whether different mechanisms allow HIV to persist in these distinct reservoirs, and the degree to which different therapies can affect each reservoir. PMID:23852128

OBJECTIVE: To characterize the findings of behavioral hearing assessment in HIV-positive individuals who received and did not receive antiretroviral treatment. METHODS: This research was a cross-sectional study. The participants were 45 HIV-positive individuals (18 not exposed and 27 exposed to antiretroviral treatment) and 30 control-group individuals. All subjects completed an audiological evaluation through pure-tone audiometry, speech audiometry, and high-frequency audiometry. RESULTS: The hearing thresholds obtained by pure-tone audiometry were different between groups. The group that had received antiretroviral treatment had higher thresholds for the frequencies ranging from 250 to 3000 Hz compared with the control group and the group not exposed to treatment. In the range of frequencies from 4000 through 8000 Hz, the HIV-positive groups presented with higher thresholds than did the control group. The hearing thresholds determined by high-frequency audiometry were different between groups, with higher thresholds in the HIV-positive groups. CONCLUSION: HIV-positive individuals presented poorer results in pure-tone and high-frequency audiometry, suggesting impairment of the peripheral auditory pathway. Individuals who received antiretroviral treatment presented poorer results on both tests compared with individuals not exposed to antiretroviral treatment. PMID:25029578

Unhealthy alcohol use is common among HIV-positive patients, yet effective evidence-based treatments are rarely provided in clinical settings providing HIV care. Further, given patient variability in response to initial treatments, stepped care approaches may be beneficial. We describe the rationale, aims and study design for the current StartingTreatment forEthanol inPrimary care Trials (STEP Trials); three parallel randomized controlled effectiveness trials being conducted in five Infectious Disease Clinics. Participants meeting criteria for: 1) at-risk drinking, 2) moderate alcohol use with liver disease (MALD), or 3) alcohol use disorder (AUD) are randomized to integrated stepped care versus treatment as usual. For those with at-risk drinking or MALD, integrated stepped care starts with a one session brief intervention and follow-up 2-week telephone booster. Based on pre-specified nonresponse criteria, participants may be "stepped up" at week 4 to receive four sessions of motivational enhancement therapy (MET) and "stepped up" again at week 12 for addiction physician management (APM) and consideration of alcohol pharmacotherapy. For those with AUD, integrated stepped care begins with APM. Non-responders may be "stepped up" at week 4 to receive MET and again at week 12 for a higher level of care (e.g. intensive outpatient program). The primary outcome is alcohol consumption assessed at 24weeks, and secondary outcome is the VACS Index, a validated measure of HIV morbidity and mortality risk. Results from the STEP Trials should inform future research and the implementation of interventions to address unhealthy alcohol use among HIV-positive individuals.

The Caribbean has the highest adult HIV prevalence in the world after sub-Saharan Africa (2011). One sub-population in the Dominican Republic is the migratory Batey community primarily comprised of Haitian immigrants with limited access to healthcare and HIV prevalence rates of between 3.0% and 9.0%, compared to 0.7% nationally. This retrospective cohort study describes the cumulative retention from diagnosis to virological suppression for newly-diagnosed HIV-infected adults presenting to the Clínica de Familia and its Batey programme in La Romana, during 2011. Of the patients diagnosed with HIV, 65% entered into care, 59% completed immunologic testing, 53% were eligible for antiretroviral therapy (ART) initiation, 36% initiated ART within three months of eligibility and 27% were retained in care. Seventeen per cent of those retained on ART with a 12-month viral load measure had undetectable viral load. Attrition primarily occurred before ART initiation. The Batey programme had a first step lost-to-follow-up of 88% compared to 20% at the clinic (p < 0.001). This retrospective study details the continuum of care and indicates where structural changes must occur to increase continuity between steps. The manuscript results are important to help implement programmes to enhance engagement and retention in HIV primary care. © The Author(s) 2015.

Background High delivery maternal plasma HIV-1 RNA level (viral load, VL) is a risk factor for mother to child transmission and poor maternal health. Objective To identify factors associated with detectable VL at delivery despite initiation of highly active antiretroviral therapy (HAART) during pregnancy. Design Multicenter observational study. Setting 67 US AIDS clinical research sites. Patients HIV-1-positive pregnant women who initiated HAART during pregnancy. Measurements Descriptive summaries and associations between socio-demographic, HIV disease, treatment and pregnancy-related risk factors and detectable VL (>400copies/mL) at delivery. Results Between October 2002 and December 2011, 671 women met inclusion criteria and 13% had detectable VL at delivery. Factors associated with detectable VL included multiparity (16.4% vs 8% nulliparous, p=0.002), black non-Hispanic ethnicity (17.6% vs 6.6% Hispanic and 6.6% white/non-Hispanic, p<0.001), 11th grade or less education (17.6% vs.12.1% high school graduate and 6.7% some college or higher, p=0.013), and initiation of HAART in third trimester (23.9% vs 12.3% second and 8.6% first, p=0.002), timing of HIV diagnosis prior to current pregnancy (16.1% vs 11% during current pregnancy, p=0.051), and timing of first prenatal visit in 3rd trimester (33.3% vs 14.3% second and 10.5% first, p=0.002). Women who experienced treatment interruptions or reported poor medication adherence during pregnancy were more likely to have detectable VL at delivery than women with no interruptions or who reported better adherence. Limitations Women entered the study at varying times during pregnancy and for this and other reasons there was incomplete data on many covariates. Conclusions In this large U.S.-based cohort of HIV-1 positive women, 13% of women who initiated HAART during pregnancy had detectable VL at delivery. The timing of HAART initiation and prenatal care along with medication adherence during pregnancy appear to be

Acute kidney injury (AKI), which is common among HIV-positive individuals, may contribute to the excess burden of chronic kidney disease (CKD) in this patient population; however, conventional clinical methods to detect AKI do not capture kidney injury sufficiently early to prevent irreversible damage. Further, large observational and interventional studies of AKI generally exclude HIV-positive persons in spite of their disproportionate risk. The Predictors of Acute Renal Injury Study (PARIS) is a prospective observational cohort study among HIV-positive individuals established to determine the ability of candidate kidney injury biomarkers to predict future hospitalized clinical AKI, to characterize hospitalized subclinical AKI, and to discern the risk of progressive kidney disease following subclinical and clinical AKI. Among the candidate kidney injury markers, we will select the most promising to translate into a clinically viable, multiplex panel of urinary biomarkers which we will integrate with clinical factors to develop a model prognostic of risks for AKI and subsequent kidney function decline. This study has a targeted enrollment of 2000 participants. The overall follow-up of participants consists of two phases: 1) a 5-year active follow-up phase which involves serial evaluations at enrollment, annual clinic visits, and among participants who are hospitalized during this period, an evaluation at index hospitalization and 3 and 12 months post-hospitalization; and 2) a subsequent passive follow-up phase for the duration that the participant receives medical care at The Johns Hopkins Hospital. This study will serve as an important resource for future studies of AKI by establishing a repository with both ambulatory and inpatient biospecimens, a resource that is currently lacking in existing HIV clinical cohorts and studies of AKI. Upon completion of this study, the resulting prognostic model which will incorporate results from the multiplex HIV-AKI Risk Pane

Background Antiretroviral treatment for HIV is gradually being made available across sub-Saharan Africa. With antiretroviral treatment, HIV can be approached as a chronic, manageable condition rather than a shorter-term issue of palliative care. This treatment involves repeated interaction between health staff and patients for ongoing check-ups and prescription refills. Objective This study aimed to understand patient and healthcare staff perceptions of good clinical antiretroviral treatment care. Design Over 100 h of ethnographic observation at healthcare sites; interviews and focus groups with 25 healthcentre workers (mostly nurses), 53 HIV-positive adults taking ARVs and 40 carers of children on ART. The data were analyzed using thematic content analysis. Setting Three healthcare sites providing free antiretroviral drugs in rural Zimbabwe, where the adult HIV infection rate is approximately 20%. Results Contrary to reports of poor antiretroviral treatment adherence and task-oriented rather than patient-oriented nursing, our study found great patient commitment to adherence, outstanding nurse dedication and a pervasive sense of hope about coping with HIV. Within this context however there were some situations where patients and nurses had different expectations of the medical encounter, leading to stress and dissatisfaction. Patients and staff both emphasized the importance of nurse kindness, understanding, confidentiality and acceptance (i.e. treating HIV patients ‘like normal’) and patient adherence to medical directions. However, nurses at times overlooked the negative effects of long wait times and frequent hospital visits. Further, nurses sometimes conflated medical adherence with general patient obedience in all aspects of the nurse–patient relationships. Patients and staff were frustrated by the ambiguity and unpredictability surrounding key elements of hospital visits such as how much patients had to pay for service, how long it would take to be

The increased risk of coronary artery disease in human immunodeficiency virus (HIV) positive patients is collectively contributed to by the human immunodeficiency virus and antiretroviral-associated dyslipidaemia. In this study, we investigate the characterisation of the plasma lipid profiles of treated HIV patients and the relationship of 316 plasma lipid species across multiple lipid classes with the risk of future cardiovascular events in HIV-positive patients. In a retrospective case-control study, we analysed plasma lipid profiles of 113 subjects. Cases (n = 23) were HIV-positive individuals with a stored blood sample available 12 months prior to their diagnosis of coronary artery disease (CAD). They were age and sex matched to HIV-positive individuals without a diagnosis of CAD (n = 45) and with healthy HIV-negative volunteers (n = 45). Association of plasma lipid species and classes with HIV infection and cardiovascular risk in HIV were determined. In multiple logistic regression, we identified 83 lipids species and 7 lipid classes significantly associated with HIV infection and a further identified 74 lipid species and 8 lipid classes significantly associated with future cardiovascular events in HIV-positive subjects. Risk prediction models incorporating lipid species attained an area under the receiver operator characteristic curve (AUC) of 0.78 (0.775, 0.785)) and outperformed all other tested markers and risk scores in the identification of HIV-positive subjects with increased risk of cardiovascular events. Our results demonstrate that HIV-positive patients have significant differences in their plasma lipid profiles compared with healthy HIV-negative controls and that numerous lipid species were significantly associated with elevated cardiovascular risk. This suggests a potential novel application for plasma lipids in cardiovascular risk screening of HIV-positive patients.

To compare QuantiFERON®-TB Gold and tuberculin skin testing as diagnostic tests for intraocular tuberculosis in HIV positive and negative patients. A prospective study evaluating two different tests to help diagnose intraocular tuberculosis. Thirty-five of 106 patients (33.0%) were diagnosed with intraocular tuberculosis including 11 (31.4%) with HIV infection. Patients were 6.95 times more likely to have intraocular tuberculosis if TST alone was positive (p < 0.001) versus 2.19 times more likely if Quantiferon alone was positive (p = 0.04). Tuberculin skin testing showed superior specificity (60.3% vs 33.3%) (p = 0.001) but similar sensitivity (90.3% vs 85.7%), positive (54.9% vs 40.5%) and negative predictive values (92.1% vs 81.5%) compared to Quantiferon. Specificity did not increase significantly if both skin testing and Quantiferon were positive. In South Africa, with its high HIV burden and limited public health resources, Quantiferon testing should not replace tuberculin skin testing as it provides little additional diagnostic information.

Background: Few data exist regarding cardiovascular risk among HIV-infected patients attending sexual health clinics (SHC) in Australia. Methods: The medical records of 188 patients attending an inner-city SHC between August 2013 and July 2014 were retrospectively reviewed for cardiovascular risk factors and associated screening and management practices. Results: Cardiovascular risk factors were common among attendees of the SHC, including smoking (38%), hypertension (14%) and dyslipidaemia (11%). Of the 188 patients, 23% reported using potentially cardiotoxic recreational drugs, 25% of dyslipidaemic patients were not on therapy and 10% of patients were hypertensive; none were prescribed treatment. A smoking cessation program was offered to all patients. Conclusion: A high prevalence of risk factors for cardiovascular disease was demonstrated. Modification of risk factors could be improved.

We aim to describe rates and risk factors of Hepatitis C Virus (HCV) diagnoses, follow-up HCV testing and HCV seroconversion from 2004-2011 in a cohort of HIV-positive persons in Spain. CoRIS is a multicentre, open and prospective cohort recruiting adult HIV-positive patients naïve to antiretroviral therapy. We analysed patients with at least one negative and one follow-up HCV serology. Incidence Rates (IR) were calculated and multivariate Poisson regression was used to estimate adjusted Rates Ratios (aIRR). Of 2112 subjects, 53 HCV diagnoses were observed, IR = 0.93/100 py (95%CI: 0.7-1.2). IR increased from 0.88 in 2004-05 to 1.36 in 2010-11 (aIRR = 1.55; 95%CI: 0.37-6.55). In men who have sex with men (MSM) from 0.76 to 1.10 (aIRR = 1.45; 95%CI: 0.31-6.82); in heterosexual (HTX) subjects from 1.19 to 1.28 (aIRR = 1.08; 95%CI: 0.11-10.24). HCV seroconversion rates decreased from 1.77 to 0.65 (aIRR = 0.37; 95%CI: 0.12-1.11); in MSM from 1.06 to 0.49 (aIRR = 0.46; 95%CI: 0.09-2.31); in HTX from 2.55 to 0.59 (aIRR = 0.23; 95%CI: 0.06-0.98). HCV infection risk was higher for injecting drug users (IDU) compared to HTX (aIRR = 9.63;95%CI: 2.9-32.2); among MSM, for subjects aged 40-50 compared to 30 or less (IRR = 3.21; 95%CI: 1.7-6.2); and among HTX, for female sex (aIRR = 2.35; 95%CI: 1.03-5.34) and <200 CD4-count (aIRR = 2.39; 95%CI: 0.83-6.89). We report increases in HCV diagnoses rates which seem secondary to intensification of HCV follow-up testing but not to rises in HCV infection rates. HCV IR is higher in IDU. In MSM, HCV IR increases with age. Among HTX, HCV IR is higher in women and in subjects with impaired immunological situation.

Objectives We aim to describe rates and risk factors of Hepatitis C Virus (HCV) diagnoses, follow-up HCV testing and HCV seroconversion from 2004–2011 in a cohort of HIV-positive persons in Spain. Methods CoRIS is a multicentre, open and prospective cohort recruiting adult HIV-positive patients naïve to antiretroviral therapy. We analysed patients with at least one negative and one follow-up HCV serology. Incidence Rates (IR) were calculated and multivariate Poisson regression was used to estimate adjusted Rates Ratios (aIRR). Results Of 2112 subjects, 53 HCV diagnoses were observed, IR = 0.93/100py (95%CI: 0.7–1.2). IR increased from 0.88 in 2004–05 to 1.36 in 2010–11 (aIRR = 1.55; 95%CI: 0.37–6.55). In men who have sex with men (MSM) from 0.76 to 1.10 (aIRR = 1.45; 95%CI: 0.31–6.82); in heterosexual (HTX) subjects from 1.19 to 1.28 (aIRR = 1.08; 95%CI: 0.11–10.24). HCV seroconversion rates decreased from 1.77 to 0.65 (aIRR = 0.37; 95%CI: 0.12–1.11); in MSM from 1.06 to 0.49 (aIRR = 0.46; 95%CI: 0.09–2.31); in HTX from 2.55 to 0.59 (aIRR = 0.23; 95%CI: 0.06–0.98). HCV infection risk was higher for injecting drug users (IDU) compared to HTX (aIRR = 9.63;95%CI: 2.9–32.2); among MSM, for subjects aged 40–50 compared to 30 or less (IRR = 3.21; 95%CI: 1.7–6.2); and among HTX, for female sex (aIRR = 2.35; 95%CI: 1.03–5.34) and <200 CD4-count (aIRR = 2.39; 95%CI: 0.83–6.89). Conclusion We report increases in HCV diagnoses rates which seem secondary to intensification of HCV follow-up testing but not to rises in HCV infection rates. HCV IR is higher in IDU. In MSM, HCV IR increases with age. Among HTX, HCV IR is higher in women and in subjects with impaired immunological situation. PMID:25549224

Oropharyngeal candidiasis is the most common fungal infection in hospitalized patients with acquired immune deficiency syndrome (AIDS). Its progression results in invasive infections, which are a significant cause of morbidity and mortality. This study aimed to quickly and accurately identify Candida spp. from oral mucosa of AIDS patients recruited at Presidente Vargas Hospital, in São Luís city, Brazil and to evaluate the sensitivity profile of these fungi to antifungals by using an automated system. Isolates were collected from oropharyngeal mucosa of 52 hospitalized AIDS patients, under anti-viral and antifungal therapies. Patients were included in research if they were HIV-positive, above 18 years of age and after obtaining their written consent. CHROMagar®Candida and the automated ViteK-2®system were used to isolate and identify Candida spp., respectively. Antifungal susceptibility testing was performed using the ViteK-2®system, complemented with the Etest®, using the drugs amphotericin B, fluconazole, flucytosine, and voriconazole. Oropharyngeal candidiasis had a high prevalence in these hospitalized AIDS patients (83%), and the most prevalent species was Candida albicans (56%). Antifungal susceptibility test showed that 64.7% of the Candida spp. were susceptible, 11.8% were dose-dependent sensitive, and 23.5% were resistant. All the Candida krusei and Candida famata isolates and two of Candida glabrata were resistant to fluconazole. Most of AIDS patients presented oropharyngeal candidiasis and C. albicans was the most frequently isolated species. The results showed high variability in resistance among isolated species and indicates the need to identify the Candida spp. involved in the infection and the need to test antifungal susceptibility as a guide in drug therapy in patients hospitalized with AIDS. This is the first relate about AIDS patients monitoring in a public hospital in São Luís concerning the precise identification and establishing of

In January 2014, the European Medicines Agency issued a marketing authorization for dolutegravir (DTG), a second-generation integrase strand transfer inhibitor for HIV treatment. The study aimed at determining the incremental cost-effectiveness ratio (ICER) of the use of DTG+backbone compared with raltegravir (RAL)+backbone, darunavir (DRV)+ritonavir(r)+backbone and efavirenz/tenofovir/emtricitabine (EFV/TDF/FTC) in HIV-positive treatment-naïve patients and compared with RAL+backbone in treatment-experienced patients, from the Italian National Health Service's point of view. A published Monte Carlo Individual Simulation Model (ARAMIS-DTG model) was used to perform the analysis. Patients pass through mutually exclusive health states (defined in terms of diagnosis of HIV with or without opportunistic infections [OIs] and cardiovascular disease [CVD]) and successive lines of therapy. The model considers costs (2014) and quality of life per monthly cycle in a lifetime horizon. Costs and quality-adjusted life years (QALYs) are dependent on OI, CVD, AIDS events, adverse events and antiretroviral therapies. In treatment-naïve patients, DTG dominates RAL; compared with DRV/r, the ICER obtained is of 38,586 €/QALY (6,170 €/QALY in patients with high viral load) and over EFV/TDF/FTC, DTG generates an ICER of 33,664 €/QALY. In treatment-experienced patients, DTG compared to RAL leads to an ICER of 12,074 €/QALY. The use of DTG+backbone may be cost effective in treatment-naïve and treatment-experienced patients compared with RAL+backbone and in treatment-naïve patients compared with DRV/r+backbone and EFV/TDF/FTC considering a threshold of 40,000 €/QALY.
Increased risk of mortality and loss to follow-up among HIV-positive patients with oropharyngeal candidiasis and malnutrition prior to ART initiation – A retrospective analysis from a large urban cohort in Johannesburg, South Africa
Evans, Denise; Maskew, Mhairi; Sanne, Ian
Objective We investigated the effect of oropharyngeal candidiasis (OC) and body mass index (BMI) prior to ART initiation on treatment outcomes of HIV-positive patients. Methods Treatment outcomes included failure to increase CD4 count by ≥50 or ≥100cells/mm3 or failure to suppress viral load (<400copies/ml) at 6- or 12-months in addition to loss to follow-up (LTFU) and mortality by 12-months. Risk and hazard ratios were estimated using log-binomial regression and Cox proportional hazards models, respectively. Results Baseline CD4 <100cells/mm3, low BMI (<18.5 kg/m2), low hemoglobin and elevated aspartate transaminase were associated with OC at ART initiation. Patients with low BMI with/without OC were at risk of mortality (Hazard Ratio (HR)2.42 95%CI 1.88–3.12; HR1.87 95% CI 1.54-2.28) and LTFU (HR1.36 95%CI 1.02–1.82; HR1.55 95% CI 1.30-1.85). Conclusion Low BMI (with/without OC) at ART initiation was associated with poor treatment outcomes. Conversely, normal BMI with OC was associated with adequate CD4 response and reduced LTFU compared to without OC. PMID:22669142

Recently kidney transplantation has become an accepted treatment modality for the treatment of HIV infected patients with end-stage renal diseases. For such treatment it is required stability of clinical and laboratory parameters related to HIV infection and the use of highly active antiretroviral therapy. In this report we present the first two cases in Brazil of patients with HIV infection transplanted with organs from deceased donors performed successfully in our institution. The interactions between immunosuppressive and antiretroviral drugs, the co-infections, cardiovascular risk profile and the high incidence of acute rejection remain the major problems to be dealt with in these patients.

Background Despite the widely documented success of antiretroviral therapy (ART), stakeholders continue to face the challenges of poor HIV treatment outcomes. While many studies have investigated patient-level causes of poor treatment outcomes, data on the effect of health systems on ART outcomes are scarce. Objective We compare treatment outcomes among patients receiving HIV care and treatment at a public and private HIV clinic in Johannesburg, South Africa. Patients and methods This was a retrospective cohort analysis of ART naïve adults (≥18.0 years), initiating ART at a public or private clinic in Johannesburg between July 01, 2007 and December 31, 2012. Cox proportional-hazards regression was used to identify baseline predictors of mortality and loss to follow-up (>3 months late for the last scheduled visit). Generalized estimating equations were used to determine predictors of failure to suppress viral load (≥400 copies/mL) while the Wilcoxon rank-sum test was used to compare the median absolute change in CD4 count from baseline to 12 months post-ART initiation. Results 12,865 patients initiated ART at the public clinic compared to 610 at the private clinic. The patients were similar in terms of sex and age at initiation. Compared to public clinic patients, private clinic patients initiated ART at higher median CD4 counts (159 vs 113 cells/mm3) and World Health Organization stage I/II (76.1% vs 58.5%). Adjusted hazard models showed that compared to public clinic patients, private clinic patients were less likely to die (adjusted hazard ratio [aHR] 0.50; 95% confidence interval [CI] 0.35–0.70) but were at increased risk of loss to follow-up (aHR 1.80; 95% CI 1.59–2.03). By 12 months post-ART initiation, private clinic patients were less likely to have a detectable viral load (adjusted relative risk 0.65; 95% CI 0.49–0.88) and recorded higher median CD4 change from baseline (184 cells/mm3 interquartile range 101–300 vs 158 cells/mm3 interquartile

Background Peripheral arterial disease (PAD) is a clinical manifestation of atherosclerosis and mainly refers to elderly patients, having a negative impact on their functionality and quality of life. The findings of previous studies in HIV-infected patients have shown that cardiovascular risk is higher and PAD occurs more frequently than in the general population. There are also contradictory observations. Much less is known about the ankle-brachial index (ABI) value in asymptomatic HIV-infected patients. The aim of this study was to evaluate the prevalence of PAD and ankle-brachial index abnormalities as well as to determine risk factors related to the disease in a group of Polish HIV–positive patients. Methods and Findings One hundred and eleven young to middle aged HIV–positive subjects and 40 noninfected subjects were enrolled into the study. Resting ABI measurements were performed and cardiovascular risk was analysed as well. Subgroups were created according to the ABI values: low (PAD), borderline, normal, high and altered ABI. Symptomatic PAD was observed in 2 HIV–positive patients, asymptomatic PAD was not diagnosed. The ABI value is lower and more varied, in 22.5% of the study group altered ABI values were found. Six subjects demonstrated borderline ABI, and 15 high ABI, including >1.4. In the control group no low or very high values were reported. A relation between low ABI and cardiovascular family history and between altered ABI and high–density–lipoprotein cholesterol (HDL–C) level was demonstrated. Conclusions In young and middle–aged HIV–positive patients, symptomatic PAD prevalence is comparable to that observed in the overall population. Among asymptomatic patients PAD is not reported. The ABI value in HIV–positive patients is more varied compared to the HIV–negative subjects; the altered ABI shows a strong relation with low HDL–C levels and metabolic syndrome. PMID:25503743

HIV prevention has become a new priority for HIV clinicians, as their patients live longer and more sexually active lives. Prevention interventions can be effective in clinical settings, but first patients must be screened and inconsistent condom use must be disclosed. Audio computer-assisted self-interviews (ACASI) are an effective way to elicit this sensitive information. We assessed condom use by ACASI among 198 English- or Spanish-speaking HIV patients at 2 community hospital-based HIV clinics in Queens and the Bronx, New York. Among 120 patients reporting sex with a regular partner in the past 4 weeks, 41 (34%) reported not using a condom every time and 22 (18%) reported never using a condom. Among 81 reporting sex with a casual partner in the past 4 weeks, 21 (26%) reported not using a condom every time and 12 (15%) reported never using a condom. Overall, 24 of 129 sexually active patients (19%) reported never using a condom. In a multivariable model controlling for age, race/ethnicity, gender, and HIV exposure category, depression symptoms (Center for Epidemiological Studies Depression Scale [CES-D] score >/= 16; p = 0.03) and self-reported antiretroviral medication non-adherence (=95% doses in past 3 days; p = 0.03) were significantly associated with never using a condom with a regular or casual partner. ACASI interviews may be an effective way of identifying patients in clinical settings who require prevention counseling as well as other psychosocial services.
In 1991, the United Kingdom Advisory Panel (UKAP) was set up under the aegis of the Expert Advisory Group on AIDS (EAGA) to consider individual cases of HIV infected healthcare workers. Policy and guidance relating to HIV infected healthcare workers is set out in a Department of Health report. Although more recently the EAGA has advised that an HIV positive dentist may under certain conditions provide clinical treatment for patients who are also HIV positive, the advice from UKAP relating to exposure-prone procedures means, in effect, that dentists who become HIV positive must cease contemporary clinical dentistry. The plight of dentists who become HIV positive and face this situation has been poignantly described as '...the dental practice equivalent of clearing your desk and being escorted off the premises.'

The prerequisite for an “undetectable” HIV viral load has restricted access to transplantation for HIV-infected kidney recipients. However, HCV-infected recipients, due the historic limitations of HCV therapy in patients with renal disease, are commonly viremic at transplant and have universal access. In order to compare the effect of HIV, HCV and HIV/HCV co-infection on kidney transplant patient and allograft outcomes, we performed a retrospective study of kidney recipients transplanted from January 1996 through December 2013. In multivariable analysis, patient (hazard ratio 0.90, 95% confidence interval 0.66–1.24) and allograft survival (0.60, 40–0.88) in 492 HIV patients did not differ significantly from the 117,791 patient uninfected reference group. This was superior to outcomes in both the 5605 patient HCV group for death (1.44, 1.33–1.56) and graft loss (1.43, 1.31–1.56) as well as the 147 patient HIV/HCV co-infected group for death (2.26, 1.45–3.52) and graft loss (2.59, 1.60–4.19). HIV infection did not adversely affect recipient or allograft survival and was associated with superior outcomes compared to both HCV infection and HIV/HCV co-infection in this population. Thus, pre-transplant viral eradication and/ or immediate post-transplant eradication should be studied as potential strategies to improve post-transplant outcomes in HCV-infected kidney recipients.

The demographic characteristics, risk behaviourand prevalence of other sexually transmitted diseases (STDs) were determined in 132 HIV-infected individuals seen in a Dermatology cum Genitourinary Clinic, Hospital Sultanah Aminah Johor Bahru. Sixty-one (46.2%) were Malays, 37.9% Chinese, 10.6% Indians and 5.3% were of other ethnic groups. The male to female ratio was 4.5:1. Most of the patients (82.5%) were between 20 to 40 years-old. Seventy (53.0%) were single, 34.1% were married and 7.5% were divorcees. The majority of them (97.7%) were heterosexual. Fifty seven (53.3%) of our male patients patronised commercial workers. Eighty-one (61.8%) were not intravenous drug users (IVDU). Of the 50 IVDUs, 24 had multiple sexual exposures. Fifty-three (48.2%) of the 109 patients screened for STDs had one or more other STDs. Thirty-four patients (31.9%) reported one STD in the past and 3.6% reported two STDs in the past. Fifty-six patients (42.4%) had developed AIDS. Thirteen had passed away. The main mode of transmission of HIV infection in this population is through heterosexual intercourse and the prevalence of STDs is high. These findings indicate a need to advocate responsible sexual behaviour and to detect as well as treat STDs early to prevent the sexual transmission of HIV.

Models of care utilizing task shifting and decentralization are needed to support growing ART programmes. We compared patient outcomes between a doctor-managed clinic and a nurse-managed down-referral site in Cape Town, South Africa. Analysis included all adults who initiated ART between 2002 and 2011 within a large public sector ART service. Stable patients were eligible for down-referral. Outcomes [mortality, loss to follow-up (LTFU), virologic failure] were compared under different models of care using proportional hazards models with time-dependent covariates. Five thousand seven hundred and forty-six patients initiated ART and over 5 years 41% (n = 2341) were down-referred; the median time on ART before down-referral was 1.6 years (interquartile range, 0.9-2.6). The nurse-managed down-referral site reported lower crude rates of mortality, LTFU and virologic failure compared with the doctor-managed clinic. After adjustment, there was no difference in the risk of mortality or virologic failure by model of care. However, patients who were down-referred were more likely to be LTFU than those retained at the doctor-managed site (adjusted hazard ratio, 1.36; 95% CI, 1.09-1.69). Increased levels of LTFU in the nurse-managed vs. doctor-managed service were observed in subgroups of male patients, those with advanced disease at initiation and those who started ART in the early years of the programme. Reorganization of ART maintenance by down-referral to nurse-managed services is associated with programme outcomes similar to those achieved using doctor-driven primary care services. Further research is necessary to identify optimal models of care to support long-term retention of patients on ART in resource-limited settings. © 2014 John Wiley & Sons Ltd.

Introduction We aimed to assess any factors associated with dysplasia regression and with HPV clearance in a cohort of HIV+ patients, with particular focus on cART and gender. Methods Asymptomatic HIV+ patients of the San Paolo Infectious Disease (SPID) cohort who underwent anoscopy/gynaecological evaluation were enrolled. Anal/cervical brushing were analyzed for: HPV-PCR detection/genotyping (HR-HPV), cytologic abnormalities (Bethesda System 2001: LSIL-HSIL). Demographics and HIV-related parameters were evaluated at baseline. Activated CD8+/CD38+ lymphocytes were measured (flow citometry). Patients were examined at baseline (T0) and at 12–18 months visit (T1). HPV clearance was defined as negativisation of HPV at T1; SIL regression (SIL-R) and progression (SIL-P) were defined as change from HSIL/LSIL to a lower-grade/absence of dysplasia and as change from absence of HSIL/LSIL to a higher-grade dysplasia at T1, respectively. Mann Whitney test, Chi-square test and multivariate logistic regression were used. Results A total of 189 patients were examined, 60 (32%) were women. One hundred fifty patients (79%) were HPV+, 113 (75%) harboured HR-HPV; 103 (68%) showed LSIL/HSIL at T0 (32% of women and 65% of men) (all were HPV-positive). No differences in demographics and HIV-related markers were found between patients with SIL-P (33, 41%) and patients with SIL-R (47, 59%). HPV+ patients who cleared HPV (28, 18%) were found to be more frequently female, heterosexual infected, more frequently on cART and with lower Log10 HIV-RNA and lower levels of CD8+/CD38+ % compared with HPV persistence group (Table 1). No differences in PI exposure were found between the two groups (p=.08). Interestingly, also when only HR-HPV were considered, clearance was associated with exposure to cART (naïve 4%, vs cART 86%, p=.048). In multivariate analysis, heterosexuals (AOR 5.123, 95% CI 1.5–17.5 vs homosexuals) were independently associated to HPV clearance, whereas CD8+/CD38+% (AOR 0

Background Sequential addition of tenofovir disoproxil fumarate (TDF) is often needed for patients coinfected with HIV and hepatitis B virus (HBV) who develop HBV resistance to lamivudine after combination antiretroviral therapy (cART) containing only lamivudine for HBV. We aimed to assess the virological response of HBV to add-on TDF in patients coinfected with lamivudine-resistant HBV. Methods Between November 2010 and December 2014, 33 HIV/HBV-coinfected patients with lamivudine-resistant HBV and 56 with lamivudine-susceptible HBV were prospectively included. TDF plus lamivudine was used to substitute zidovudine or abacavir plus lamivudine contained in cART in patients with lamivudine-resistant HBV infection, while patients with lamivudine-susceptible HBV infection received TDF plus lamivudine as backbone of cART. Serial determinations of plasma HBV DNA load, HBV serologic markers, and liver and renal functions were performed after initiation of TDF-containing cART. Results Of 89 patients included, 38.6% tested positive for HBV envelope antigen (HBeAg) at baseline. The plasma HBV DNA level at enrollment of lamivudine-resistant and lamivudine-susceptible group were 6.1 ± 2.2 log10 and 6.0 ± 2.2 log10 copies/mL, respectively (p = 0.895). The cumulative percentage of HBV viral suppression in lamivudine-resistant and lamivudine-susceptible group was 81.8% and 91.1% at 48 weeks, respectively (p = 0.317), which increased to 86.7% and 96.2% at 96 weeks, respectively (p = 0.185). At 48 weeks, 11 patients testing HBeAg-positive at baseline failed to achieve viral suppression. In multivariate analysis, the only factor associated with failure to achieve viral suppression at 48 weeks was higher HBV DNA load at baseline (odds ratio, per 1-log10 copies/mL increase, 1.861; 95% CI, 1.204–2.878). At 48 weeks, HBeAg seroconversion was observed in 5 patients (1 in the lamivudine-resistant group and 4 in the lamivudine-susceptible group; p = 0.166). During the study period, HBs

To assess implementation of provider-initiated testing and counselling (PITC) for HIV in Malawi. A review of PITC practices within 118 departments in 12 Ministry of Health (MoH) facilities across Malawi was conducted. Information on PITC practices was collected via a health facility survey. Data describing patient visits and HIV tests were abstracted from routinely collected programme data. Reported PITC practices were highly variable. Most providers practiced symptom-based PITC. Antenatal clinics and maternity wards reported widespread use of routine opt-out PITC. In 2014, there was approximately 1 HIV test for every 15 clinic visits. HIV status was ascertained in 94.3% (5293/5615) of patients at tuberculosis clinics, 92.6% (30,675/33,142) of patients at antenatal clinics and 49.4% (6871/13,914) of patients at sexually transmitted infection clinics. Reported challenges to delivering PITC included test kit shortages (71/71 providers), insufficient physical space (58/71) and inadequate number of HIV counsellors (32/71) while providers from inpatient units cited the inability to test on weekends. Various models of PITC currently exist at MoH facilities in Malawi. Only antenatal and maternity clinics demonstrated high rates of routine opt-out PITC. The low ratio of facility visits to HIV tests suggests missed opportunities for HIV testing. However, the high proportion of patients at TB and antenatal clinics with known HIV status suggests that routine PITC is feasible. These results underscore the need to develop clear, standardised PITC policy and protocols, and to address obstacles of limited health commodities, infrastructure and human resources. © 2016 The Authors.

Cervical intraepithelial neoplasias (CIN) are closely associated with oncogenic subtypes of the human papillomavirus (HPV). In the presence of this virus, it is known that the activation or suppression of immune system is the key to the development, progression and/or regression of cervical lesions. Therefore, the objective of this study is to compare the local immune response among HIV-seropositive and seronegative patients with cervical intraepithelial neoplasia regarding the expression of T lymphocytes (CD3+, CD4+ and CD8+), B lymphocytes (CD20+) and natural killers cells (CD56+) in the cervical stroma. A cross-sectional study of paraffin blocks containing cervical tissue after conization by the Loop Electrosurgical Excision Procedure (LEEP) from 47 HIV-seropositive and 38 seronegative patients with CIN. Cervical stroma immunohistochemistry was performed in the CIN area. The Fisher's exact test was used for the statistical analysis. When HIV-seropositive and seronegative women were compared, the seropositive women had a higher count of CD8+ T lymphocytes (52.1% versus 28.9%, P<0.04). Considering CIN degree (CIN 1 and CIN 2/3), the HIV-seronegative patients with CIN 1 had a low count of CD20+B-lymphocytes (7.1%) in comparison with CIN 1 HIV seropositive and with CIN 2/3 HIV-seronegative patients, respectively 50% (P<0.018) and 54.5% (P<0.0048). The HIV infection and degree of CIN influenced the cytotoxic lymphocytes inducing an increase in the number of cells high count of CD20+ lymphocytes with CIN 1.

Persistent immune activation and chronic inflammation significantly contribute to non-AIDS morbidity in HIV-infected patients. The HIV inhibitor maraviroc (MVC) targets the cellular chemokine CCR5 HIV co-receptor, which is involved in important inflammatory pathways. MVC could have significant anti-inflammatory and anti-atherosclerotic effects, also reducing immune activation. We designed a pilot study to determine which plasma biomarkers of inflammation, endothelial dysfunction, and hypercoagulability were modified by MVC in 2 groups of 10 patients starting MVC-free or MVC-containing regimens. Ten age- and gender-matched healthy controls were also included. We found higher levels of all inflammatory biomarkers in HIV-infected patients compared to healthy controls. Both groups showed decreasing levels of interleukin (IL)-17, IL-10, and macrophage inflammatory protein (MIP)-1a following the achievement of viral suppression. Vascular cell adhesion molecule (VCAM)-1 levels were decreased in the MVC group and increased in the MVC-free group. In conclusion, some inflammatory biomarkers tend to decrease with the salvage regimen; MVC was not associated with a better impact on these measured markers.

To identify risk factors for loss to follow-up (LTFU) in an HIV-infected pediatric population in Dar es Salaam, Tanzania, between 2004 and 2011. Longitudinal analysis of 6236 HIV-infected children. We conducted a prospective cohort study of 6236 pediatric patients enrolled in care and treatment in Dar es Salaam from October 2004 to September 2011. LTFU was defined as missing a clinic visit for >90 days for patients on ART and for >180 days for patients in care and monitoring. The relationship of baseline and time-varying characteristics to the risk of LTFU was examined using a Cox proportional hazards model. A total of 2130 children (34%) were LTFU over a median follow-up of 16.7 months (interquartile range, 3.4-36.9). Factors independently associated with a higher risk of LTFU were age ≤2 years (relative risk [RR] = 1.59, 95% CI: 1.40 to 1.80), diarrhea at enrollment (RR = 1.20, 95% CI: 1.03 to 1.41), a low mid-upper arm circumference for age (RR = 1.20, CI: 1.05 to 1.37), eating protein-rich foods ≤3 times a week (RR = 1.39, 95% CI: 1.05 to 1.90), taking cotrimoxazole (RR = 1.39, 95% CI: 1.06 to 1.81), initiating onto antiretrovirals (RR = 1.37, 95% CI: 1.17 to 1.61), receiving treatment at a hospital instead of a local facility (RR = 1.39, 95% CI: 1.06 to 1.41), and starting treatment in 2006 or later (RR = 1.10, 95% CI: 1.04 to 1.16). Health workers should be aware of pediatric patients who are at a greatest risk of LTFU, such as younger and undernourished patients, so that they can proactively counsel families about the importance of visit adherence. Findings support decentralization of HIV care to local facilities as opposed to hospitals.

Tenofovir-based first-line antiretroviral therapy (ART) is recommended globally. To evaluate the impact of its incorporation into the World Health Organization (WHO) guidelines, we examined treatment failure and drug resistance among a cohort of patients on tenofovir-based first-line ART at the Academic Model Providing Access to Healthcare, a large HIV treatment programme in western Kenya. We determined viral load (VL), drug resistance and their correlates in patients on ≥six months of tenofovir-based first-line ART. Based on enrolled patients' characteristics, we described these measures in those with (prior ART group) and without (tenofovir-only group) prior non-tenofovir-based first-line ART using Wilcoxon rank sum and Fisher's exact tests. Among 333 participants (55% female; median age 41 years; median CD4 336 cells/µL), detectable (>40 copies/mL) VL was found in 18%, and VL>1000 copies/mL (WHO threshold) in 10%. Virologic failure at both thresholds was significantly higher in 217 participants in the tenofovir-only group compared with 116 in the prior ART group using both cut-offs (24% vs. 7% with VL>40 copies/mL; 15% vs. 1% with VL>1000 copies/mL). Failure in the tenofovir-only group was associated with lower CD4 values and advanced WHO stage. In 35 available genotypes from 51 participants in the tenofovir-only group with VL>40 copies/mL (69% subtype A), any resistance was found in 89% and dual-class resistance in 83%. Tenofovir signature mutation K65R occurred in 71% (17/24) of the patients infected with subtype A. Patients with K65R had significantly lower CD4 values, higher WHO stage and more resistance mutations. In this Kenyan cohort, tenofovir-based first-line ART resulted in good (90%) virologic suppression including high suppression (99%) after switch from non-tenofovir-based ART. Lower virologic suppression (85%) and high observed resistance levels (89%) in the tenofovir-only group impact future treatment options, support recommendations for

One way of addressing malnutrition among HIV/AIDS patients is through the Food by Prescription program (FBP) and many studies have explained the treatment outcomes after therapeutic food supplementation, though available evidences on adherence levels and factors associated with these sorts of programs are limited. The findings of this study would therefore contribute to the existing knowledge on adherence to Ready-to-Use Therapeutic/Supplementary Food (RUF) in Ethiopia. A facility-based, cross-sectional study supplemented with qualitative methods was conducted among 630 adult HIV + patients. Their level of adherence to RUF was measured using the Morisky 8-item Medication Adherence Scale (MMAS-8). The total score on the MMAS-8 ranges from 0 to 8, with scores of <6, 6 to <8, and 8 reflecting low, medium, and high adherence, respectively. Patients who had a low or a moderate rate of adherence were considered non-adherent. The level of adherence was found to be 36.3% with a 95.0% response rate. With the exception of the educational status, other socio-demographic variables had no significant effect on adherence. Those who knew the benefits of the FBP program were 1.78 times more likely to adhere to the therapy than the referent groups. On the other hand, patients who were not informed on the duration of the treatment, those prescribed with more than 2 sachets/day and had been taking RUF for more than 4 month were less likely to adhere. The main reasons for non-adherence were not liking the way the food tasted and missing follow-up appointments. Stigma and sharing and selling food were the other reasons, as deduced from the focus group discussion (FGD) findings. The observed level of adherence to the FBP program among respondents enrolled in the intervention program was low. The major factors identified with a low adherence were a low level of education, poor knowledge on the benefits of RUF, the longer duration of the program, consuming more than two prescribed sachets

Occult hepatitis B infection (OBI) is a frequent finding in human immunodeficiency virus (HIV)-infected patients. While several related mutations in the hepatitis B virus (HBV) genome have been reported, their distinct impact on HBsAg synthesis is largely obscure. Thirty-one (18%) out of 172 HIV-infected patients, who were selected from HBsAg-negative patients, were positive for HBV-DNA assigned as being OBI-positive. We generated a series of expression constructs of variant HBsAg with "a" determinant amino acid substitutions including P127L, P127T, S136Y, and P127T + S136Y using site-directed mutagenesis. The expression of variant HBsAg was examined by transient transfection in hepatoma cells, followed by HBsAg immunoassay and immunofluorescence stained with specific anti-HBs antibodies. The potential impact of amino acid substitutions at different positions for conformational changes in the HBsAg was investigated using bioinformatics. All variants comprising either single or combined mutations resulted in significantly reduced HBsAg detection in supernatants and in cell lysates of hepatoma cells transfected with the constructs. Moreover, intracellular immunofluorescence staining of cytoblocks showed perinuclear and cytoplasmic fluorescence of HBsAg constructs with significantly diminished fluorescent intensity in comparison to the wild type. Altered protein conformations by predictive models, indicating an impaired detection by the host's immune response as well as by commercial antibody-based test assays. Mutations in the "a" determinant region of HBV as often found in OBI remarkably impair the detection of HBsAg from serum and infected cells, emphasizing the relevance of alternative methods such as HBV-DNA quantification for high-risk groups like HIV-infected individuals.

Natural history of anal intraepithelial neoplasia and anal cancer is not fully understood. Factors associated with cytological abnormalities and predictors of progression to high-grade anal intraepithelial neoplasia still deserve investigation. The aim of this cross-sectional study was to assess the prevalence of HPV types, the relationship between HPV genotypes, HPV 16/18 viral load and cytological abnormalities in male and female HIV-infected patients. One hundred and twenty-two (72.6%) patients were infected with HPV, 75 (61%) had multiple HPV infection, and 94 (77%) had high-risk HPV infection. The most frequently identified HPV types were HPV 16 (64%), HPV 6 (39%), HPV 18 (31%), HPV 53 (14.7%), HPV 33 (10.6%), HPV 11 (8.2%), HPV 70 (5.7%), and HPV 61 (4.9%). The HPV types which were most frequently found in combination were HPV 6 + 16 (9.8%), 6 + 16 + 18 (8.2%), 16 + 18 (6.6%), 6 + 18 (4.9%), 16 + 33 (3.3%), 16 + 53 (3.3%). Median HPV16 and 18 viral loads were 6.1 log10 copies/10(6) cells [IQR 5.0-7.3] and 6.1 log10 copies/10(6) cells [IQR 5.7-6.0], respectively. Male gender (P = 0.03, OR: 1.2 [1.0-1.4]) and homo/bisexual transmission routes (P = 0.044, OR: 1.4 [1.0-1.9]) were associated with HPV 16 infection. An HPV 16 viral load cut-off ≥5.3 log10 copies/10(6) cells and a CD4+ cell count ≤200/µl were independent factors associated with abnormal cytology. In the absence of national consensus guidelines, a strict regular follow-up at shorter intervals is recommended for HIV-infected patients with abnormal cytology, especially low grade squamous intraepithelial lesions, an HPV 16 viral load ≥5.3 log/10(6) cells and a CD4+ cell count ≤200/µl.

Abstract The purpose of this study was to assess humoral antibody responses as a function of disease progression (DP) in a well-defined HIV+ cohort. We quantified antibodies to HIV-1 gp120, Gag, and CD4 receptor by enzyme-linked immunosorbent assay in sera from a cohort of 97 HIV+ subjects at defined stages of DP. We also measured antibody-dependent cellular cytotoxicity (ADCC) as a function of the clinical status of the patients. We purified antibodies to CD4 and gp120 and assessed them for specificity, ability to block gp120 binding to target cells, ability to block virus infection, and ability to facilitate ADCC. All of the HIV+ patient samples were positive for antibodies to HIV gp120 and p24 and 80% showed evidence of hypergammaglobulinemia. Approximately 10% of cohort members were positive for antibodies to CD4, but we noted no significant correlation relevant to DP. There were statistically significant differences between the groups concerning the level of humoral response to gp120 and Gag. However, we observed no distinction in ability of anti-gp120 antibodies purified from each group to neutralize infection. In addition, there was a statistically significant difference in ADCC, with elite controllers exhibiting significantly lower levels of ADCC than the other five groups. We detected IgA anti-gp120 antibodies, but did not correlate their presence with either DP or ADCC levels. The results are consistent with the interpretation that the humoral antibody response to the antigens assessed here represents a signature of the level of viremia but does not correlate with clinical status of HIV infection.

Background It is unclear whether antiretroviral (ART) naive HIV-positive individuals with high CD4 counts have a raised mortality risk compared with the general population, but this is relevant for considering earlier initiation of antiretroviral therapy. Methods Pooling data from 23 European and North American cohorts, we calculated country-, age-, sex-, and year-standardised mortality ratios (SMRs), stratifying by risk group. Included patients had at least one pre-ART CD4 count above 350 cells/mm3. The association between CD4 count and death rate was evaluated using Poisson regression methods. Findings Of 40,830 patients contributing 80,682 person-years of follow up with CD4 count above 350 cells/mm3, 419 (1.0%) died. The SMRs (95% confidence interval) were 1.30 (1.06-1.58) in homosexual men, and 2.94 (2.28-3.73) and 9.37 (8.13-10.75) in the heterosexual and IDU risk groups respectively. CD4 count above 500 cells/mm3 was associated with a lower death rate than 350-499 cells/mm3: adjusted rate ratios (95% confidence intervals) for 500-699 cells/mm3 and above 700 cells/mm3 were 0.77 (0.61-0.95) and 0.66 (0.52-0.85) respectively. Interpretation In HIV-infected ART-naive patients with high CD4 counts, death rates were raised compared with the general population. In homosexual men this was modest, suggesting that a proportion of the increased risk in other groups is due to confounding by other factors. Even in this high CD4 count range, lower CD4 count was associated with raised mortality. PMID:20638118

Worldwide, there is a high co-endemicity of HIV and H. pylori infection and there is growing evidence that H. pylori co-infection is associated with parameters of HIV disease progression. The objective of this study was to investigate the prevalence of H. pylori infection, and the association with clinical, immunological and virological parameters in a large cohort of HIV-infected individuals and uninfected controls in a West African country. HIV-patients (n = 1,095) and HIV-negative individuals (n = 107) were recruited at a university hospital in Ghana. H. pylori status was determined using stool antigen testing. HIV-related, clinical and socio-demographic parameters were recorded and analyzed according to H. pylori status. The prevalence of H. pylori infection was significantly lower in HIV-positive compared to HIV-negative individuals (51.5 vs. 88%, p<0.0001). In HIV patients, H. pylori prevalence decreased in parallel with CD4+ T cell counts. In ART-naïve HIV-infected individuals, but not in those taking ART, H. pylori infection was associated with higher CD4 cell counts (312 vs. 189 cells/μL, p<0.0001) and lower HIV-1 viral loads (4.92 vs. 5.21 log10 copies/mL, p = 0.006). The findings could not be explained by socio-demographic confounders or reported use of antibiotics. Having no access to tap water and higher CD4+ T cell counts were identified as risk factors for H. pylori infection. H. pylori prevalence was inversely correlated with the degree of immunosuppression. In ART-naïve individuals, H. pylori infection is associated with favorable immunological and virological parameters. The underlying mechanisms for this association are unclear and warrant investigation.

Introducción: la leishmaniasis visceral o kala azar es la presentación clínica más grave. En México, es una enfermedad rara por lo que su diagnóstico es tardío y generalmente culmina en la muerte del paciente. Se describe a un paciente VIH positivo que desarrolló leishmaniasis visceral. El objetivo es explicar sus características fisiopatológicas y de su tratamiento. Caso clínico: hombre de 45 años de edad, quien ingresó al hospital por cuadro crónico de diarrea sanguinolenta, distensión abdominal, dolor tipo cólico, pérdida de peso y fiebre. A la exploración física se identificó paciente febril con dolor en fosa iliaca derecha y hepatoesplenomegalia. La prueba ELISA para VIH resultó positiva y el ultrasonido hizo evidente una tumoración en ciego, por lo que se realizó biopsia. El informe histopatológico indicó que se trataba de leishmaniasis. Conclusiones: en los pacientes con leishmaniasis e infección por VIH existe pobre respuesta al tratamiento y la mortalidad es alta, causada por la menor respuesta inmune del huésped. En la literatura especializada se sugiere el tratamiento establecido para la infección por VIH combinado con miltefosine y anfotericina B liposomal para la leishmaniasis.

Abstract Linking and engaging HIV-positive patients in care is the key bridging step to glean the documented health and prevention advantages of antiretroviral therapy (ART). In China, HIV transmission among men who have sex with men (MSM) is surging, yet many HIV-positive MSM do not use HIV care services. We conducted a qualitative study in order to help positive interventions to promote linkage-to-care in this key population. Four focus group discussions (FGD) were held among HIV-positive MSM in Beijing, China, to ascertain knowledge, beliefs, attitudes, and practices related to HIV care. FGD participates highlighted six major barriers of linkage to/engagement in HIV care: (1) perceived discrimination from health care workers; (2) lack of guidance and follow-up; (3) clinic time or location inconvenience; (4) privacy disclosure concerns; (5) psychological burden of committing to HIV care; and (6) concerns about treatment. Five major sub-themes emerged from discussions on the facilitators of linkage to/engagement in care: (1) peer referral and accompaniment; (2) free HIV care; (3) advocacy from HIV-positive MSM counselors; (4) extended involvement for linking MSM to care; and (5) standardization of HIV care (i.e., reliable high quality care regardless of venue). An understanding of the barriers and facilitators that may impact the access to HIV care is essential for improving the continuum of care for MSM in China. Findings from our study provide research and policy guidance for how current HIV prevention and care interventions can be enhanced to link and engage HIV-positive MSM in HIV care. PMID:26784360

Research on pregnancy termination (PT) largely assumes HIV status is the only reason why HIV-positive women contemplate abortion. As antiretroviral treatment (ART) becomes increasingly available and women are living longer, healthier lives, the time has come to consider the influence of other factors on HIV-positive women’s reproductive decision-making. Because ART has been free and universally available to Brazilians for more than two decades, Brazil provides a unique context in which to explore these issues. Twenty-five semi-structured interviews exploring women’s PT decision-making were conducted with women receiving care at the Reference Centre for HIV/AIDS in Salvador, Brazil. Interviews were transcribed, translated into English, and coded for analysis. HIV played different roles in women’s decision-making. 13 HIV-positive women did not consider PT. Influential factors described by those who did consider PT included fear of HIV transmission, fear of HIV-related stigma, family size, economic constraints, partner and provider influence, as well as lack of access to such services as PT and abortifacients. For some HIV-positive women in Brazil, HIV can be the only reason to consider PT, but other factors are significant. A thorough understanding of all variables affecting reproductive decision-making is necessary for enhancing services and policies and better meeting the needs and rights of HIV-positive women.

Mental health outcomes among HIV-positive gay men are generally poorer than in the broader population. However, not all men in this population experience mental health problems. Although much is known about factors associated with depression and anxiety among HIV-positive gay men, little is known about factors associated with positive mental health. Such knowledge can be useful for optimizing well-being support programs for HIV-positive gay men. In this study, we examined flourishing, which broadly covers most aspects of positive mental health. A sample of 357 Australian HIV-positive gay men completed a survey on their mental health and well-being, including the Flourishing Scale. Given the lack of previous research, we explored a wide range of psychosocial factors, including demographics, stigma, discrimination, and social support, to identify key factors linked to flourishing. The sample showed a similar level of flourishing to those in general population samples. Several independent factors were found to be associated with flourishing outcomes. Those who were most likely to be flourishing tended to have low or no internalized HIV-related stigma, were employed, received higher levels of practical support, had a sense of companionship with others, and felt supported by family. These and other findings presented in this article may be used to help inform strategies for promoting optimal levels of mental health, and its associated general health benefits, among HIV-positive gay men.

Since human immunodeficiency virus (HIV) is known to lead to modifications of immune function and interrelationships among malnutrition, anergy and drug addiction have been shown, the aim of this work was to assess the nutritional status of 36 male heroin addicts under a period of detoxication (3 months). They were divided into two groups: (1) HIV negative (n = 20) and (2) HIV positive (n = 16); heights, weights and serum albumin concentration were measured and immune function was tested, using delayed hypersensitivity skin tests containing 7 antigens. No significant differences in anthropometric measurements were found between both groups, but anthropometric improvement was shown in every patient after the detoxication period. Serum albumin, often used as a classical index of malnutrition, remained within the normal values in both groups. The whole response to skin tests was depressed in both groups and no significant differences were shown between them. Therefore, these results might suggest that in spite of the apparent anthropometric recovery and the normal values of albumin, a subclinical malnutrition was indicated by the depressed immune function, which was more noticeable in the HIV-positive group.

The presentation and course of Sexually transmitted diseases(STI) may be altered by presence of coexisting HIV status. Aim of the study was to study the prevalence of STI in 50 females with HIV infection and 50 females without HIV infection and to study the pap smear of patients to look for any cellular changes (dysplasia) due to sexually transmitted infections. Material and methods: The present study was an observational study, which was undertaken on 100 females with STIs (50 females with coexistent HIV infection and 50 females without HIV infection), in the age group 15-49 years attending Skin and VD OPD of Rajindra hospital, Patiala. Results: In our study, the commonest presenting complaint in case of both HIV positive (66%) and HIV negative (80%) women was vaginal discharge. PAP smear abnormalities were present in 28 (56%) HIV positive women and 11 (22%) HIV negative women. In case of HIV positive women, the inflammation was trichomonal in 4 (8%), bacterial in 2 (4%), fungal in 2 (4%) and non-specific in 20 (40%) patients. In HIV negative women, the inflammation was trichomonal in 2 (4%) patients, bacterial in 2 (4%) patients and non-specific in 7 (14%) patients. The difference in abnormality seen in PAP smear between HIV positive and HIV negative women is statistically significant only in case of non-specific inflammation which is more common in case of HIV positive women. Conclusion: From the present study, it was concluded vaginal discharge was the commonest presenting complaint in both HIV positive and HIV negative women, though the commonest cause of vaginal discharge was candidiasis in HIV positive females and bacterial vaginosis in HIV negative females. Also, PAP smear abnormalities were significantly higher in HIV positive women than HIV negative women. So it is important that HIV positive women should have complete gynecological evaluation including a PAP smear with aggressive screening of STIs. PMID:26392656

Oral manifestations in HIV positive children were observed in thirty-eight HIV infected children that have received care at the Special Care Dentistry Center (SCDC) of the School of Dentistry, University of Sao Paulo. Results have shown that 52.63% of the children presented at least one oral manifestation related with HIV/AIDS. Angular cheilitis occurred in 28.94%, parotid gland bilateral enlargement, pseudomembranous candidiasis and erythematous candidiasis in 18.42%, conventional gingivitis in 13.15%, herpes simplex in 5.26%, hairy leukoplakia, recurrent aphthous ulcer and condyloma acuminatum in 2.63%. Although enamel hypoplasia occurred in 23.68%, this could not be attributed specifically to HIV infection.
The greatest source of happiness and tension comes from the partner in a relationship. Couples enjoy planning their future and exploring all possible options. When one member of this union is HIV-positive, it forces the couple to live more in the present. The futures may be different for each. The stories of two couples who are facing this complication are described. Speaking openly about satisfying each other sexually helps these couples to be creative. In the early days of the AIDS epidemic, there were stories of abandonment. Now there is greater understanding. AIDS cannot take away the love these partners feel for each other, it may change their perspective on life, but it makes them realize that life is worth living.

Rationale: Kidney transplantation has become standard of care for carefully selected patients living with human immunodeficiency virus (HIV) and end-stage renal disease (ESRD) in the highly active antiretroviral therapy (HAART) era. American and European prospective cohort studies have reported similar patient and graft survival compared with HIV-negative kidney transplant recipients. Despite an increased rate of acute rejection, partially due to drug interactions, HIV immunovirologic parameter generally remains under control during immunosuppression. A few cases of kidney transplantation between HIV-infected patients were done in South Africa and showed favorable results. No cases of kidney transplantation from an HIV-positive donor in Canada have previously been reported. Presenting concerns of the patient: A 60-year-old Canadian man with HIV infection presented in 2007 with symptoms compatible with acute renal failure secondary to IgA nephropathy. Chronic kidney disease resulted after the acute episode. Diagnoses: Hemodialysis was started in 2012. The patient was referred for a kidney transplantation evaluation. Interventions: The patient underwent kidney transplantation from an HIV-positive donor in January 2016. The recipient’s antiretroviral regimen consisted of abacavir, lamivudine, and dolutegravir. No drug interactions have been reported between these antiretrovirals and the maintenance immunosuppressive regimen used. Outcomes: The outcome at 7 months post transplantation was excellent, with good graft function and adequate control of HIV replication, in the absence of opportunistic infections at a time when immunosuppression is at its highest intensity. No acute rejection was reported. An episode of bacteremic graft pyelonephritis due to Enterococcus faecalis was successfully treated after transplantation. Novel finding: With careful selection of patient, kidney transplantation between HIV-infected patients is a viable option. The use of antiretroviral

AIDS-related mortality among HIV-positive adolescents has risen by 50% despite the scale up of antiretroviral therapy (ART). ART maladherence likely plays a role in the increase of AIDS-related deaths among adolescents and has shown to be associated with psychosocial and mental health difficulties. Addressing the specific mental health needs of HIV-positive adolescents is critical to ending the HIV epidemic. This cross-sectional study prospectively enrolled HIV-positive adolescents (12-24 years) in Moshi, Tanzania. A structured questionnaire was administered that included questions about home, school, adherence, and measures of stigma (Berger Stigma Scale) and mental health. Mental health measures included depression (Patient Health Questionnaire-9), emotional/behavioral difficulties (Strengths and Difficulties Questionnaire), and traumatic experiences/post-traumatic stress symptoms (The University of California Los Angeles-post-traumatic stress disorder-Reaction Index). Mental health difficulties were prevalent among HIV-positive adolescents and were associated with incomplete adherence and stigma. Resources are needed to reduce HIV stigma and address mental health among HIV-positive adolescents in low-resource settings. This will improve not only mental health, but may also improve ART adherence and virologic suppression, improving overall health of the individual and reducing the risk of HIV transmission to others.

Objective: Human papillomavirus (HPV) is the major cause of cervical carcinoma and cervical intraepithelial neoplasia worldwide. Certain HPV types have a strong association with and probably a causative role in the pathogenesis of premalignant cervical lesions. Epidemiologic studies in women infected by the human immunodeficiency virus (HIV) have shown an increased incidence of squamous intraepithelial lesions (SILs), whichwere predominantly high-grade. Six to 30 per cent of women diagnosed with atypical squamous cells of undetermined significance (ASCUS) on a Papanicolaou (Pap) smear harbor SIL in normal screening populations. This study was undertaken to determine the presence of low- and high-risk HPV types in women infected by HIV and to correlate the results to those of the Pap smear. Study design: HPV DNA typing (low- and high-risk) by Digene™ (Digene Corporation, Gathesburg, MD) hybrid capture methodology was performed on cervical swabs from 209 HIV-positive women. The results of HPV typing were correlated with those of the Pap smear in a retrospective analysis. Results: One hundred and one women (48%) tested positive for HPV subtypes by DNA typing by the hybrid capture method. Of these, 64 patients (63%) had Pap smears whichwere read as being normal, having benign cellular changes, or having ASCUS (favor reactive process). Of these, 19 patients tested positive for both high-risk and low-risk subtypes, 32 patients tested positive only for high-risk subtypes, and 13 patients tested positive only for low-risk subtypes. Conclusion: HPV subtyping identifies a significant group of HIV-positive women who are at risk for developing cervical intraepithelial neoplasia, although they may not show significant abnormalities on their Pap smears.

Supine heart rate variability (HRV) and autonomic tests were carried to determine whether autonomic activity was affected in HIV positive patients. The pressor response following handgrip and cold pressor test was blunted in HIV+ patients, and the degree of dysfunction correlated with CD4 cell counts. The extent of autonomic impairment was mild and subclinical.
The question of the moral acceptability of infertility treatment to HIV positive persons raises a number of interesting ethical points regarding the responsibility of the infertility specialist for the outcome of his or her actions. The analysis of the physician's responsibility is conducted within the framework of accomplice liability. The physician is a collaborator in the parental project of the principals—that is, the intentional parents. Both causal contribution and intention are considered as elements of complicity. It is concluded that a two per cent risk of vertical transmission when the woman is HIV positive is insufficient to blame the infertility specialist who helps her to conceive. Helping an infertile HIV positive infertile couple to have a child does not constitute reckless behaviour. When the couple is fertile, infertility treatment is directed at risk reduction and falls under the physician's obligation to act in the best interests of his patients. PMID:14662809

We describe the clinical and post-mortem findings of a case of rapidly progressive, ultimately fatal primary effusion lymphoma (PEL) arising in an HIV-positive man two years after renal transplantation. Disseminated multi-organ involvement associated with a peculiar intravascular pattern of growth, as seen in this case, has only been reported once previously. This is also, to our knowledge, the first detailed description of a lymphoma arising post-transplant in an HIV-positive patient. This article is protected by copyright. All rights reserved.

A second case of rosacea-like demodicosis in an HIV-positive child was seen at our center. No such cases have previously been published. The present case is a 2-year-old boy, the son of an HIV-positive mother, who responded well to oral erythromycin and topical metronidazole. The frequency of rosacea-like eruptions in HIV-negative children is very low. However, the incidence of these eruptions in HIV-positive children may have been underestimated. The pathogenic role of Demodex mites is discussed as well as the possible mechanisms for an exaggerated reaction.

Background Global coverage of prevention of mother-to-child (PMTCT) services reached 53% in 2009. However the number of pregnant women who test positive for HIV in antenatal clinics and who link into long-term HIV care is not known in many resource-poor countries. We measured the proportion of HIV-positive pregnant women in Mwanza city, Tanzania, who completed the cascade of care from antenatal HIV diagnosis to assessment and engagement in care in adult HIV clinics. Methods Thirty antenatal and maternity ward health workers were interviewed about PMTCT activities. Nine antenatal HIV education sessions were observed. A prospective cohort of 403 HIV-positive women was enrolled by specially-trained clinicians and nurses on admission to delivery and followed for four months post-partum. Information was collected on referral and attendance at adult HIV clinics, eligibility for highly active antiretroviral therapy (HAART) and reasons for lack of attendance. Results Overall, 70% of PMTCT health workers referred HIV-positive pregnant women to the HIV clinic for assessment and care. Antenatal HIV education sessions did not cover on-going care for HIV-infected women. Of 310 cohort participants tested in pregnancy, 51% had received an HIV clinic referral pre-delivery. Only 32% of 244 women followed to four months post-partum had attended an HIV clinic and been assessed for HAART eligibility. Non-attendance for HIV care was independently associated with fewer antenatal visits, poor PMTCT prophylaxis compliance, non-disclosure of HIV status, and non-Sukuma ethnicity. Conclusion Most women identified as HIV-positive during pregnancy were not assessed for HAART eligibility during pregnancy or in the first four months post-partum. Initiating HAART at the antenatal clinic, improved counselling and linkages to care between PMTCT and adult HIV treatment services and reducing stigma surrounding disclosure of HIV results would benefit on-going care of HIV-positive pregnant women.

In developing countries, culture favours males for economic ventures more than females. There is evidence that allowing HIV positive women inheritance rights will mitigate negative economic consequences of HIV/AIDS and other related risks. This study aimed to examine the extent to which HIV positive women have access to family resources in Abia State, Nigeria. Data collection instruments were questionnaire, focus group discussion and interview guides using 98 HIV positive women in network of people living with HIV/AIDS. Five key informants were also interviewed to authenticate women's responses. Results showed that 85 (86.7%) of the women were denied rights to family resources. Thirty-eight (64.4%) of them had negative relationship with their family members for demanding their husbands' property. Because of limited financial assistance, the women took two types of risks in order to survive in the communities. Twenty-five women (25.5%) earned their livelihood by acting as hired labourers to others in the farm. More that half (55.1%) of the HIV positive women were practicing unprotected sex. Although as high as 79.6% of women were aware of risks of unprotected sex, 54 (55%) of them practised it. The commonest reason for taking the risk was sex partners' dislike for condom use. The high proportion of HIV positive women who were denied access to family resources, could suggest lack of care and support. If this denial continues, Government's efforts to reduce HIV prevalence would yield no significant result. There is therefore need for organized community education programme that emphasizes the benefits of empowering women living positively with HIV/AIDS economically.

Background To characterize the findings of brainstem auditory evoked potential in HIV-positive individuals exposed and not exposed to antiretroviral treatment. Material/Methods This research was a cross-sectional, observational, and descriptive study. Forty-five HIV-positive individuals (18 not exposed and 27 exposed to the antiretroviral treatment – research groups I and II, respectively – and 30 control group individuals) were assessed through brainstem auditory evoked potential. Results There were no significant between-group differences regarding wave latencies. A higher percentage of altered brainstem auditory evoked potential was observed in the HIV-positive groups when compared to the control group. The most common alteration was in the low brainstem. Conclusions HIV-positive individuals have a higher percentage of altered brainstem auditory evoked potential that suggests central auditory pathway impairment when compared to HIV-negative individuals. There was no significant difference between individuals exposed and not exposed to antiretroviral treatment. PMID:26485202

Cigarette smoking has become an important influence of morbidity and mortality for HIV-positive individuals in the era of highly active antiretroviral therapy. Although smoking is common among military personnel and veterans, the lasting impact of military service on smoking at a later stage of life has not been examined. The current study investigated present and past influences on current smoking among HIV-positive male veterans. Participants were 200 HIV-positive men served by the Veterans Affairs Medical Center. A survey was administered via audio-enhanced computer-assisted self-interview, and additional information was extracted from the computerized patient record system. Logistic regression was performed to test hypotheses concerning the participants' current situations as well as characteristics of their past military service. Having smokers in one's environment, being more depressed, and having used alcohol or drugs were associated with having smoked in the previous 30 days, whereas stronger endorsement of attitudes stating adverse effects of smoking was linked to lower likelihood of smoking. Neither having been in a military conflict nor the length of the military service was significantly related to current smoking. Remote experiences in the military did not have a sustained effect on smoking behavior years later. Implications of this study for the development of smoking cessation programs targeting HIV-positive veterans include the importance of altering attitudes about tobacco, treating underlying depression, addressing social influence, decreasing substance use, and increasing awareness of the heightened vulnerability to a variety of negative consequences of smoking among infected individuals.

Socio-demographic dimensions such as age, gender, sexual orientation, race and ethnicity are commonly included in diversity studies. With a view to helping Asian hospitality managers to manage HIV-positive employees in their workplaces through diversity management (DM) theory, this research extends the boundaries of previous diversity studies by considering Human Immunodeficiency Virus (HIV) infection as a diverse characteristic. Both quantitative and qualitative primary data were collected from purposively selected Asian hospitality managers through postal questionnaire and follow-up telephone interviews. Transformed raw data were analysed using summary statistics and template analysis. Asian hospitality managers agreed that DM would be appropriate in the management of HIV-positive employees and that it could generate substantial benefits for employees and employers. However, they believe that the successful adoption and implementation of DM is not easy; it requires training and, ideally, the recruitment of experienced directors. Nevertheless, Asian hospitality managers are confident that implementing DM to manage HIV-positive employees can enhance tolerance, improve understanding and promote equality. The purposive sampling technique and the small number of respondents have impacted the external validity of the study. However, this exploratory study initiates an equality discussion to include HIV-positive employees in DM discourse beyond antidiscrimination legislation. It also supplements the sparse literature addressing HIV-positive employees in the Asian hospitality workplace. Asian hospitality managers are advised to understand and employ DM to treat HIV-positive employees fairly to overcome hospitality workplace marginalisation, discrimination and stigmatisation.

Background There is limited knowledge about human immunodeficiency virus (HIV)-positive migrants and their experiences in the Swedish health care system. It is necessary to increase our knowledge in this field to improve the quality of care and social support for this vulnerable group of patients. Objective The aim of this study was to describe the experiences of HIV-positive migrants and their encounters with the health care system in Sweden. Design This is a Grounded Theory study based on qualitative interviews with 14 HIV-positive migrants living in Sweden, aged 29-55 years. Results 'A hybrid of access and adversity' was identified as the core category of the study. Three additional categories were 'appreciation of free access to treatment', 'the impact of the Swedish Disease Act on everyday life', and 'encountering discrimination in the general health care system'. The main finding indicated that participants experienced frustration and discrimination because they were required to provide sexual partners with information about their HIV status, which is compulsory under the Swedish Disease Act. The study also showed that the bias or fear regarding HIV infection among general health care professionals outside of the infectious diseases clinics limited the access to the general health care system for HIV-positive migrants. Conclusions The HIV-positive migrants appreciated the free access to antiviral therapy, but wished to have more time for patient-physician communications. The participants of this study felt discrimination in health care settings outside of the infectious diseases clinics. There is a need to reduce the discrimination in general health care services and to optimize the social support system and social network of this vulnerable group.

HIV and human papillomavirus (HPV) coinfection is increasing, especially in the anal canal (AC) and cervico-vaginal regions. We identified anal epithelium abnormalities related to high-risk HPV (HR-HPV) lesions in the lower genital tracts (LGTs) of HIV-positive women, described the HPV genotypes identified, and assessed the expression of E6/E7 oncogenes in coinfected patients. Ninety-eight women were enrolled in groups combining HIV status and presence or absence of HPV in the LGT. Anal and cervical smears were collected for cytology and HR-HPV assays using Cobas(®) and/or PapilloCheck(®). Samples with highly oncogenic HPV genotypes were confirmed by NucliSENS EasyQ(®). Forty-two HIV-positive (25-52; mean age 39.5) and 56 HIV-negative (18-58; mean age 35.7) patients were included. E2 and C1 groups presented AC alterations (P = 0.002); altered images for high-resolution anoscopy were higher in E1 and C2 (P < 0.001). Of the 29 women with alterations, 41.38% were HIV-negative and 58.62% were HIV-positive (P < 0.001). HIV-positive patients accounted for 29% of the anal high-grade squamous intraepithelial lesions (P = 0.015). The Cobas(®) positive result frequency was higher in three AC groups than in the other groups. There was variation in the number of HPV types in the cervico-vaginal samples among the study groups (P < 0.001). Anal cytology and anoscopy showed more altered findings in HIV-positive patients with HPV in the LGT. HR-HPV anal infections by various genotypes are common and are associated with cervical infections in HIV-positive patients. E6/E7 expression is apparently more common in the AC of HIV-positive women.

This is an exploratory study based on a qualitative approach. The objective was to investigate why HIV positive pregnant women do not follow the treatment which is recommended by the Health Ministry during the prenatal period. The individuals participating of this investigation were seven HIV positive women who, during their pregnancy, did not follow the prophylaxis treatment currently recommended. The data were collected by means of semi-structured interviews. Categories based on what these individuals reported were then stipulated and the results showed that women are in a vulnerable position regarding the negotiation of safe sex with their partners. Moreover, low social and economical conditions and lack of affection lead women to become victims of HIV/AIDS.

Low self-assertion has been noted as an important feature among patients with eating disorders. To verify, in a female population, if assertiveness is related or has a predictive capacity for the development of eating disorders. An structured clinical interview, the Eating Attitudes Test (EAT-40) and the Rathus Assertiveness Scale (RAS) were administered to 62 patients that fulfilled the DSM-IV diagnostic criteria for eating disorders and to 120 female students without eating problems. Patients with eating disorders ranked significantly higher on the EAT-40 and its factors (p <0.001) and showed a lower level of assertiveness on the RAS (p <0.001). Assertiveness measured by RAS and its factors was inversely related to EAT-40 and its items (r= -0.21). The predictive capability of the lack of self-assertion in the development of an eating disorder reached 53%, when patients with eating disorders and subjects at risk were considered together and compared to students without such disorder. Lack of assertiveness is a significant trait in patients with eating disorders; it may worsen its outcome and even perpetuate symptoms. Low self-assertion may be considered a predictive factor in the development of an eating disorder and must be managed from a preventive or therapeutic point of view.

Title I of the Ryan White CARE Act provides emergency assistance to localities disproportionately affected by HIV and AIDS. In 1999, the Title I Chicago Area HIV Services Planning Council expressed concern regarding the lack of a client-level database. In response to the Planning Council, evaluators conducted a longitudinal interview study of HIV-positive individuals who were receiving primary care at Title I funded clinics within Chicago and the surrounding collar counties. Analysis of baseline data explored gender differences in transmission risk, service utilization, and service barriers among study respondents. Among the 161 respondents, men were more likely than women to use alcohol and other drugs during sexual activity. Men were also more likely to use HIV medication. Women, however, were more likely to have someone to coordinate their HIV care. Close to half (47.2%) of these primary case patients reported at least one unmet service need, most frequently dental care, housing support and transportation. These findings suggest a continued need for HIV-related community-based services as well as increased attention to the unique experiences of both men and women within the HIV service system.

Progression of HIV/AIDS is frequently associated with frontal/subcortical dysfunction and mean reaction time (RT) slowing. Beyond group means, within-subject variability of RT has been found to be particularly sensitive to frontal/subcortical dysfunction in other populations. However, the possible relevance of RT variability to HIV/AIDS patients remains unknown. This study evaluated the relationships between RT variability and indicators such as neurocognitive, behavioral, and immunological status. A total of 46 HIV-positive adults on antiretroviral medication regimens were included in this study. Overall performance of this sample was poorer than normative means on measures of RT latency, RT variability, and traditional neurocognitive domains. Results demonstrated that the measures of RT variability were associated with global cognition, medication adherence rates, and peak immunological dysfunction, above and beyond the effects of RT latency. These preliminary findings suggest that measures of RT variability may provide enhanced sensitivity to neurocognitive disease burden in HIV/AIDS relative to more traditional measures of mean RT or cognitive function.

An understanding of men's motivations to avoid risk behavior is needed to create efficacious HIV prevention programs for HIV-positive men who have sex with men (MSM). This study investigates the relationship between sexual risk behavior and HIV prevention altruism, which is defined as the values, motivations, and practices of caretaking towards one's sexual partners to prevent the transmission of HIV. In a sample of 637 HIV-positive MSM, HIV prevention altruism significantly protects against serodiscordant unprotected anal intercourse (SDUAI) in crude analysis, but not after adjustment for drug use and compulsive sexual behavior. HIV prevention altruism is also related to not engaging in anal intercourse, but is not related to serodisclosure to secondary partners. Lack of altruism appears related to sexual risk behavior in HIV-positive MSM, although other psychological and contextual factors play significant roles. The promotion of HIV prevention altruism may provide a formidable new direction for HIV prevention programs.

Objective. The aim of this study was to compare impulsivity and risky decision making among HIV-positive and negative heroin dependent persons. Methods. We compared different dimensions of impulsivity and risky decision making in two groups of 60 HIV-positive and 60 HIV-negative male heroin dependent persons. Each group was comprised of equal numbers of current (treatment seeker) and former (abstinent) heroin addicts. Data collection tools included Balloon Analogue Risk Task (BART), Iowa Gambling Task (IGT), Barratt Impulsiveness Scale (BIS), and Zuckerman Sensation Seeking Scale (SSS). Results. In SSS, comprised of four subscales including thrill and adventure seeking (TAS), experience seeking (ES), disinhibition (DIS), and boredom susceptibility (BS), there was a borderline difference in DIS (P = 0.08) as HIV-positive group scored higher than HIV-negative group. Also, ES and total score were significantly higher among HIV-positive patients. In BART, HIV-positive subjects scored higher in risk taking than HIV-negative subjects as reflected in higher Average Number of puffs in Successful Balloons (ANSB). In BIS, HIV-positive group scored significantly higher in cognitive impulsivity (CI) (P = 0.03) and nonplanning impulsivity (NPI) (P = 0.05) in comparison to HIV-negative group. Also, current heroin addicts scored significantly higher in NPI compared to former addict HIV-negative participants (P = 0.015). IGT did not show any significant difference between groups. Conclusion. Higher levels of impulsivity and risk taking behaviors among HIV-positive heroin addicts will increase serious concerns regarding HIV transmission from this group to other opiate dependents and healthy people.

Occult hepatitis B is characterized by the absence of hepatitis B surface antigen (HBsAg) but the presence of HBV DNA. Because diagnosis of hepatitis B virus (HBV) typically includes HBsAg detection, occult HBV remains largely undiagnosed. Occult HBV is associated with increased risk of hepatocellular carcinoma, reactivation to chronic HBV during immune suppression, and transmission during blood transfusion and liver transplant. The mechanisms leading to occult HBV infection are unclear, although viral mutations are likely a significant factor. In this study, sera from 394 HIV-positive South Africans were tested for HBV DNA and HBsAg. For patients with detectable HBV DNA, the overlapping surface and polymerase open reading frames (ORFs) were sequenced. Occult-associated mutations-those mutations found exclusively in individuals with occult HBV infection but not in individuals with chronic HBV infection from the same cohort or GenBank references-were identified. Ninety patients (22.8%) had detectable HBV DNA. Of these, 37 had detectable HBsAg, while 53 lacked detectable surface antigen. The surface and polymerase ORFs were cloned successfully for 19 patients with chronic HBV and 30 patients with occult HBV. In total, 235 occult-associated mutations were identified. Ten occult-associated mutations were identified in more than one patient. Additionally, 15 amino acid positions had two distinct occult-associated mutations at the same residue. Occult-associated mutations were common and present in all regions of the surface and polymerase ORFs. Further study is underway to determine the effects of these mutations on viral replication and surface antigen expression in vitro. © 2014 Wiley Periodicals, Inc.

To determine the pattern of dental care utilisation of people living with HIV (PLHIV). A cross-sectional questionnaire survey of 239 PLHIV patients in three care centres was done. Information on sociodemographics, dental visit, risk groups, living arrangement, medical insurance and need of dental care was recorded. The EC Clearinghouse and WHO clinical staging was used to determine the stage of HIV/AIDS infection following routine oral examinations under natural daylight. Multivariate logistic regression models were created after adjusting for all the covariates that were statistically significant at univariate/bivariate levels. The majority of subjects were younger than 50 years, about 93% had not seen a dentist before being diagnosed HIV positive and 92% reported no dental visit after contracting HIV. Among nonusers of dental care, 14.3% reported that they wanted care but were afraid to seek it. Other reasons included poor awareness, lack of money and stigmatisation. Multivariate analysis showed that lack of dental care was associated with employment status, living arrangements, educational status, income per annum and presenting with oral symptoms. The area under the receiver operating curve was 84% for multivariate logistic regression model 1, 70% for model 2, 67% for model 3 and 71% for model 4, which means that the predictive power of the models were good. Contrary to our expectations, dental utilisation among PLHIV was generally poor among this group of patients. There is serious and immediate need to improve the awareness of PLHIVs in African settings and barriers to dental care utilisation should also be removed or reduced.

Despite increasing rates of HIV infection among heterosexual women in Peru, married women remain virtually invisible as a group at risk of HIV or requiring treatment. This study analyzed the intersections of HIV with machismo and marianismo, the dominant discourses in Latin America that prescribe gender roles for men and women. Data sources include recent literature on machismo and marianismo and interviews conducted with 14 HIV-positive women in Lima, Peru. Findings indicate how the stigma associated with HIV constructs a discourse that restricts the identities of HIV-positive women to those of ‘fallen women’ whether or not they adhere to social codes that shape and inform their identities as faithful wives and devoted mothers. Lack of public discourse concerning HIV-positive marianas silences women as wives and disenfranchises them as mothers, leaving them little room to negotiate identities that allow them to maintain their respected social positions. Efforts must be aimed at expanding the discourse of acceptable gender roles and behaviour for both men and women within the context of machismo and marianismo so that there can be better recognition of all persons at risk of, and living with, HIV infection. PMID:18821355

We report a case of an HIV-positive man on antiretroviral therapy (ART) who developed abdominal pain due to acute-on-chronic intestinal ischaemia secondary to superior mesenteric vein thrombosis (SMVT) requiring emergency surgery. He was found to have persistently low levels of protein C on thrombophilia screening. To the best of our knowledge, the association linking SMVT to protein C deficiency in an HIV-infected patient has never been reported in the literature. PMID:25819818

Background Globally, half of all new HIV infections occur among young people. Despite this incidence, there is a profound lack of resources for HIV-positive youth. Objective To investigate Internet access, use and acceptability as a means for health promotion and health service delivery among HIV-positive youth. Methods A community-based participatory approach was used to conduct a mixed methods research study. Thirty-five qualitative in-depth semi-structured interviews were conducted with youth (ages 12-24) living with HIV in Ontario. Also, brief structured demographic surveys were administered at the time of the interview. A stakeholder group of youth living with HIV, professionals and researchers collaboratively analyzed the data for emerging themes. Results Five main themes were identified with respect to the youth's use of and interest in the Internet as a health promotion strategy. These include: (1) high rates of Internet use and access; (2) issues around public and private terminals; (3) their use of the Internet primarily for communication and entertainment; (4) the rarity of health information seeking behavior in this group; and (5) wanting "one-stop shopping" from an e-health site. HIV-positive youth were enthusiastic about the possibility of content that was developed specifically to target them and their needs. Also, they were keen about the possibilities for increased social support that youth-specific online chat rooms and message boards might provide. Conclusion Given high rates of use, access and interest, the Internet provides an important way to reach young people living with HIV using health services and health promotion programs. The onus is on e-Health developers to understand the particular needs of HIV-positive youth and create relevant content. PMID:15471758

More relationships exist today between HIV-positive and HIV-negative partners. This article explores the underlying dynamics that might account for this phenomenon. Codependency theories may explain these relationships for some couples. For other couples, it is suggested that positive-negative homosexual relationships may be influenced by both unhealthy and healthy gay developmental experiences as well as by a sense of compassion. The article addresses both HIV-positive people choosing HIV-negative partners and vice versa. Treatment issues for the various theories are discussed and recommendations are made.

To conduct research on levels and dynamics of HIV risk behavior among HIV-positive patients in clinical care, use this research to design a clinician-initiated HIV prevention intervention for HIV-positive patients, and evaluate the acceptability of the intervention to clinicians and patients and the fidelity with which it can be delivered by clinicians. Study 1 (elicitation research) involved focus groups with HIV-positive patients and HIV care clinicians to understand the dynamics of HIV risk behavior among HIV-positive patients and how to integrate HIV prevention into routine clinical care. Study 2 (acceptability and intervention fidelity) involved the evaluation of 1455 medical visits by experimental intervention patients (N = 231) for acceptability and fidelity of the clinician-initiated HIV prevention intervention. Elicitation research with patients and clinicians identified critical HIV prevention information, motivation, and behavioral skills deficits in HIV-positive patients as well as risky sexual behavior. These findings were integrated into a theory-based HIV prevention intervention initiated by clinicians that proved acceptable to clinicians and patients and that clinicians were able to implement with adequate fidelity. HIV prevention interventions by clinicians treating HIV-positive patients can and should be integrated into routine clinical care.

The purpose of the study was to assess the prevalence and the type of cardiac abnormalities in patients with HIV infection. Echocardiographic examination (M-mode, two-dimensional and Doppler) was performed in 51 patients (40 male, 11 female), whose mean age was 29 +/- 10 years; 48 of them (94%) were intravenous drug addicts, 3 (6%) homosexuals. Diagnosis was AIDS in 19 (37%) patients, AIDS related complex in 19 (37%) and asymptomatic infection in 13 (26%). Echocardiography was normal in 13 subjects. Pericardial effusion was found in 19 patients (in 8 of them, this was the only cardiac abnormality). Valve vegetations were found in 16 patients (3 of them had pericardial effusion, 5 had ventricular dilatation or wall motion abnormalities, 1 had both pericardial and myocardial impairment). Myocardial dysfunction was found in 18 patients: 11 had left ventricular dilatation (5 with wall hypokinesia), 1 had right ventricular enlargement, 1 had biventricular dilatation and 5 had only wall motion abnormalities (diffuse or localized). During the follow-up 9 patients died: 8 had AIDS, 1 was asymptomatic. Eight subjects died during hospitalization (none because of cardiac causes) and one at home for sudden unexplained death. Echocardiography had displayed myocardial dysfunction in 6 of them, thickened pericardium in 1 and was normal in 2. Pathologic examination (performed in 8 subjects) showed cardiac enlargement in 3 subjects, thickened pericardium in 2 and valve vegetation in 1. One subject had histopathologic diagnosis of myocarditis and 7 had non specific histologic abnormalities. The study shows a cardiac involvement in 75% of HIV infected patients: 35% had myocardial dysfunction, 37% pericardial disease, 31% infective endocarditis.(ABSTRACT TRUNCATED AT 250 WORDS)

Undiagnosed HIV infection in children carries significant risks and national guidelines recommend that children of HIV-positive parents be tested. We reviewed the testing of HIV-positive patients' children in those new to our service from April 2008 to December 2009. Of the 86 women, 95% were asked about children. Of the 243 men, 53 were heterosexual or bisexual, and 190 identified themselves as men who have sex with men (MSM). Parental status was determined in 37 (70%) of heterosexual and bisexual men and in 14 (17%) of 84 MSM with a history of previous female partners. All untested children apart from one lived in their country of origin. In MSM, recording of parental status was uncommon. Following this audit, clinic proformas were changed to document the parental status of men of all sexual orientations, and the HIV status of all children.
The Indian navy has been accused of discrimination against their 6000 HIV-positive personnel. This was brought about by the limitations imposed on symptom-free HIV-positive patients, categorized as 'S2A2' by the navy. 'S2A2' are barred from diving, submarines, or high altitude operations and certain noncombat positions. Furthermore, they are immediately invalidated from re-engagement or promotion once they become symptomatic. However, the navy defended its policies claiming that they are nondiscriminatory and in accordance with internationally accepted practices. The navy further added that its primary concerns about combat-related duties are the safety of their personnel and the success of their operational missions and not discrimination.

Integrated data on hepatitis B virus (HBV) patterns, HBV genotypes and mutations are lacking in human immunodeficiency virus type 1 (HIV-1) co-infected patients from Africa. This survey was conducted in 2010-2013 among 762 HIV-1-positive adults from Gabon who were predominantly treated with 3TC-based antiretroviral treatment. HBV patterns were identified using immunoassays detecting total antibody to hepatitis B core antigen (HBcAb), hepatitis B surface antigen (HBsAg), IgM HBcAb, hepatitis B e antigen (HBeAg), antibody to HBsAg (HBsAb) and an in-house real-time PCR test for HBV DNA quantification. Occult hepatitis B (OBI) was defined by the presence of isolated anti-HBc with detectable serum HBV DNA. HBV genotypes and HBV mutations were analyzed by PCR-direct sequencing method. Seventy-one (9.3%) patients tested positive for HBsAg, including one with acute hepatitis B (0.1%; 95% CI, 0.0%-0.2%), nine with HBeAg-positive chronic hepatitis B (CHB) (1.2%; 95% CI, 0.6%-2.2%), 16 with HBeAg-negative CHB (2.1%; 95% CI, 1.2%-3.3%) and 45 inactive HBV carriers (5.9%; 95% CI, 4.4%-7.8%). Sixty-one (8.0%; 95% CI, 6.2%-10.1%) patients showed OBI. Treated patients showed similar HBV DNA levels to those obtained in untreated patients, regardless of HBV patterns. Around 15.0% of OBI patients showed high (>1,000 UI/mL) viremia. The mutation M204V/I conferring resistance to 3TC was more common in HBV/A (47.4%) than in HBV/E isolates (0%) (P = .04). Our findings encouraged clinicians to promote HBV vaccination in patients with no exposure to HBV and to switch 3TC to universal TDF in those with CHB.

A 46-year-old, HIV-positive transgender woman of South American ethnicity consulted our outpatient clinic to discuss the possibilities of a surgical, secondary neovaginal reconstruction because of complete stenosis of her inverted penile skin-lined neovagina. She was taking abacavir/lamivudine and nevirapine as antiretroviral therapy. We successfully performed a total laparoscopic sigmoid vaginoplasty without any complications. There was no short-term morbidity and no complications were reported after 15 months of follow-up. To our knowledge, this is the first report of laparoscopic sigmoid vaginoplasty as vaginal reconstruction in a HIV-positive transgender woman. Worldwide, transgender women have a high burden of HIV infection. This report shows that intestinal vaginoplasty is a feasible surgical option for HIV-positive transgender women in need of vaginal reconstruction. Because patients are again able to engage in penetrative sexual intercourse, we emphasise the importance of practicing safe sex and early initiation of adequate antiretroviral therapy in this patient population.

To determine the prevalence of Pneumocystis pneumonia (PCP), a major opportunistic infection in AIDS patients in Europe and the USA, in Cameroon. Induced sputum samples from 237 patients without pulmonary symptoms (126 HIV-positive and 111 HIV-negative outpatients) treated at a regional hospital in Cameroon were examined for the prevalence of Pneumocystis jirovecii by specific nested polymerase chain reaction (nPCR) and staining methods. CD4 counts and the history of antiretroviral therapy of the subjects were obtained through the ESOPE database system. Seventy-five of 237 study participants (31.6%) were colonised with Pneumocystis, but none showed active PCP. The Pneumocystis colonisation rate in HIV-positive subjects was more than double that of HIV-negative subjects (42.9% vs. 18.9%, P < 0.001). In the HIV-positive group, the colonisation rate corresponds to the reduction in the CD4 lymphocyte counts. Subjects with CD4 counts >500 cells/μl were colonised at a rate of 20.0%, subjects with CD4 counts between 200 and 500 cells/μl of 42.5%, and subjects with CD4 counts <200 cells/μl of 57.1%. Colonisation with Pneumocystis in Cameroon seems to be comparable to rates found in Western Europe. Prophylactic and therapeutic measures against Pneumocystis should be taken into account in HIV care in western Africa. © 2014 John Wiley & Sons Ltd.

Abstract Antiretroviral nonadherence is a strong determinant of virologic failure and is negatively correlated with survival. HIV-positive African American youth have lower antiretroviral adherence and treatment engagement than other populations. We assessed the feasibility and acceptability of a telehealth (remote videoconferencing) medication counseling intervention as an innovative approach to address these disparities. HIV-positive African American youth (18-29 years old) on antiretrovirals were enrolled in a telehealth medication counseling session, followed by a semi-structured qualitative interview to explore likes/dislikes of the format, modality, and content; potential impact on adherence; privacy issues; and interaction quality. Fourteen participants with a mean age of 24 years, who were 86% male, and had a mean self-reported adherence in the past month of 89%, were interviewed. Participants stated that they liked telehealth, would use it if offered in clinic/research settings, and indicated that their privacy was maintained. Participants described telehealth as convenient and efficient, with positive impact on their knowledge. Telehealth provided a modality to interact with providers that participants described as less intimidating than in-person visits. Telehealth is feasible and acceptable for delivering medication counseling to HIV-positive African American youth when conducted in a controlled clinical setting and may improve quality of patient-provider dialogue. Use of telehealth may lead to more disclosure of treatment difficulties, increased patient comfort, and improved health education.

This chapter examines how HIV-positive adults made sense of their diagnosis. Individuals experienced a perspective transformation or change in worldview, which was found to hold over time. Changes in meaning schemes or individual beliefs and assumptions occurred over time.
[Name removed], a tattoo shop owner, violated State law by refusing to tattoo H. [Name removed]., an HIV-positive customer. The ensuing case received national attention. [Name removed] filed a complaint with the Civil Rights Commission in April 1994 after 8-Ball Tattoo refused to tattoo him because he is HIV-positive. The hearing examiner, Franklin A. Martens, found that the shop violated a State disability-rights statute that says it is illegal to deny a public accommodation to someone based on HIV infection. The shop has a policy not to tattoo anyone who is HIV-positive because of the risk of being stuck by a tattoo needle. The hearing examiner rejected the owner's assertion that tattooing an HIV-positive customer posed too great a risk of infection. In testimony, Dr. Robert Crane, who specializes in HIV treatment at Riverside Methodist Hospital, said tattoo artists are no more likely than health care workers to become infected through an accidental needlestick. The Commission is scheduled to decide whether to accept the hearing examiner's recommendation that a cease-and-desist order be issued against 8-Ball Tattoo.

Worldwide, more than 3 million children are infected with HIV and, without treatment, mortality among these children is extremely high. Both acute and chronic malnutrition are major problems for HIV-positive children living in resource-limited settings. Malnutrition on a background of HIV represents a separate clinical entity, with unique medical and social aetiological factors. Children with HIV have a higher daily calorie requirement than HIV-negative peers and also a higher requirement for micronutrients; furthermore, coinfection and chronic diarrhoea due to HIV enteropathy play a major role in HIV-associated malnutrition. Contributory factors include late presentation to medical services, unavailability of antiretroviral therapy, other issues surrounding healthcare provision and food insecurity in HIV-positive households. Treatment protocols for malnutrition have been greatly improved, yet there remains a discrepancy in mortality between HIV-positive and HIV-negative children. In this review, the aetiology, prevention and treatment of malnutrition in HIV-positive children are examined, with particular focus on resource-limited settings where this problem is most prevalent.

Current Department of Health advice for mothers who are HIV positive is not to breastfeed. The aim of this paper is to encourage debate on this subject among health-care professionals who care for such mothers. Both formula feeding and breastfeeding could be considered a risk in such circumstances, but information and options can be make this choice safer.

Patient-centered nutrition education and counseling can improve the health of HIV-positive persons. This article describes the development and implementation of a Spanish-language, community clinic-based, individually tailored, and culturally specific nutrition curriculum for HIV-positive Latinos living on the U.S.-Mexico border. Important considerations made in serving this population include low acculturation to U.S. culture, monolingual Spanish speaking, cross-border mobility, and dietary behaviors influenced by access to culturally preferred regional foods, some of which may not be nutritionally optimal. Challenges to curriculum implementation and lessons learned for replication of the curriculum in other clinical settings are discussed.

Introduction: Cigarette smoking has become an important influence of morbidity and mortality for HIV-positive individuals in the era of highly active antiretroviral therapy. Although smoking is common among military personnel and veterans, the lasting impact of military service on smoking at a later stage of life has not been examined. The current study investigated present and past influences on current smoking among HIV-positive male veterans. Methods: Participants were 200 HIV-positive men served by the Veterans Affairs Medical Center. A survey was administered via audio-enhanced computer-assisted self-interview, and additional information was extracted from the computerized patient record system. Results: Logistic regression was performed to test hypotheses concerning the participants’ current situations as well as characteristics of their past military service. Having smokers in one's environment, being more depressed, and having used alcohol or drugs were associated with having smoked in the previous 30 days, whereas stronger endorsement of attitudes stating adverse effects of smoking was linked to lower likelihood of smoking. Neither having been in a military conflict nor the length of the military service was significantly related to current smoking. Conclusions: Remote experiences in the military did not have a sustained effect on smoking behavior years later. Implications of this study for the development of smoking cessation programs targeting HIV-positive veterans include the importance of altering attitudes about tobacco, treating underlying depression, addressing social influence, decreasing substance use, and increasing awareness of the heightened vulnerability to a variety of negative consequences of smoking among infected individuals.

In the United States, an estimated 8500 HIV (human immunodeficiency virus) positive women gave birth in 2014. This rate appears to be increasing annually. Our objective is to examine obstetrical outcomes of pregnancy among HIV-positive women. A population-based cohort study was conducted using the Nationwide Inpatient Sample database (2003-2011) from the United States. Pregnant HIV-positive women were identified and compared to pregnant women without HIV. Multivariate logistic regression was used to estimate the adjusted effect of HIV status on obstetrical and neonatal outcomes. Among 7,772,999 births over the study period, 1997 were in HIV-positive women (an incidence of 25.7/100,000 births). HIV-infected patients had greater frequency of pre-existing diabetes and chronic hypertension, and use of cigarettes, drugs, and alcohol during pregnancy (p < 0.001). Upon adjustment for baseline characteristics, HIV-infected women had greater likelihood of antenatal complications: preterm premature rupture of membranes (OR 1.35, 95% CI 1.14-1.60) and urinary tract infections (OR 3.02, 95% CI 2.40-3.81). Delivery and postpartum complications were also increased among HIV-infected women: cesarean delivery (OR 3.06, 95% CI 2.79-3.36), postpartum sepsis (OR 8.05, 95% CI 5.44-11.90), venous thromboembolism (OR 2.21, 95% CI 1.46-3.33), blood transfusions (OR 3.67, 95% CI 3.01-4.49), postpartum infection (OR 3.00, 95% CI 2.37-3.80), and maternal mortality (OR 21.52, 95% CI 12.96-35.72). Neonates born to these mothers were at higher risk of prematurity and intrauterine growth restriction. Pregnancy in HIV-infected women is associated with adverse maternal and newborn complications. Pregnant HIV-positive women should be followed in high-risk healthcare centers.

Cervical cancer is the leading incident cancer and the main cause of cancer-related mortality among women in sub-Saharan Africa. Furthermore, HIV-infected women are at a higher risk of developing cervical cancer than HIV-negative women. The purpose of this study was to distinguish differences in characteristics of HIV-positive and HIV-negative patients with cervical cancer in Dar es Salaam, Tanzania. The HIV status of cervical cancer patients diagnosed and/or treated at Ocean Road Cancer Institute in Dar es Salaam, Tanzania, during the period 2007-2011 was abstracted from the medical records. Additional abstracted information included patient's name, age, place of residence, occupation, education, marital status, age at marriage, gravidity, and screening clinic visit results. Ocean Road Cancer Institute patients came from two sources: the screening clinic followed by treatment clinic or the treatment clinic without prior screening. HIV-positive and HIV-negative patients were compared regarding the above-listed clinical and epidemiologic factors. Multivariable analysis was also performed to assess the risk factors associated with cervical cancer treatment without prior screening at Ocean Road Cancer Institute. HIV-positive cervical cancer patients tended to be younger, with higher education and lower parity. Patients screened for cervical cancer prior to treatment were more likely to be HIV-positive (OR: 2.09, 95% CI: 1.36, 3.21), less likely to have higher disease stages (OR: 0.64, 95% CI: 0.43, 0.94), and less likely to reside outside of Dar es Salaam (OR: 0.44, 95% CI: 0.30, 0.65). Screening for cervical cancer at Ocean Road Cancer Institute is utilised by more HIV-positive patients from Dar es Salaam. Future studies should focus on identifying the reasons for lower utilisation of screening by HIV-negative patients and patients from other distant rural regions in Tanzania.

Objectives: To estimate life expectancy over 25 years in HIV-positive people and to compare their life expectancy with recent estimates for the general population, by education. Methods: Patients aged 20 years or older enrolled in the Swiss HIV Cohort Study 1988–2013 were eligible. Patients alive in 2001 were matched to up to 100 Swiss residents, by sex, year of birth, and education. Life expectancy at age 20 was estimated for monotherapy (1988–1991), dual therapy (1992–1995), early combination antiretroviral therapy (cART, 1996–1998), later cART (1999–2005) and recent cART (2006–2013) eras. Parametric survival regression was used to model life expectancy. Results: In all, 16 532 HIV-positive patients and 927 583 residents were included. Life expectancy at age 20 of HIV-positive individuals increased from 11.8 years [95% confidence interval (CI) 11.2–12.5] in the monotherapy era to 54.9 years (95% CI 51.2–59.6) in the most recent cART era. Differences in life expectancy across educational levels emerged with cART. In the most recent cART period, life expectancy at age 20 years was 52.7 years (95% CI 46.4–60.1) with compulsory education, compared to 60.0 years (95% CI 53.4–67.8) with higher education. Estimates for the general population were 61.5 and 65.6 years, respectively. Male sex, smoking, injection drug use, and low CD4+ cell counts at enrolment were also independently associated with mortality. Conclusion: In Switzerland, educational inequalities in life expectancy were larger among HIV-infected persons than in the general population. Highly educated HIV-positive people have an estimated life expectancy similar to Swiss residents with compulsory education. Earlier start of cART and effective smoking-cessation programs could improve HIV-positive life expectancy further and reduce inequalities. PMID:27831953

Women with HIV positive status are considered a hard to reach population by many. We discuss the experiences of a research team while conducting the recruiting process with both Hispanic Puerto Rican HIV positive and HIV negative populations. To provide strategies and recommendations for conducting research interventions with HIV+ and HIV- women. This study explored the communication skills between HIV+ and HIV-mothers and their adolescent daughters regarding disclosure of their status, and the discussion, or lack of, on topics related to sexuality and prevention of HIV/AIDS. This study explored the recruitment, retention and intervention processes of a qualitative research study that used focus groups to understand the communication skills between HIV+ and HIV-mothers and their adolecent daughters regarding disclosure of their status, and the discussion, or lack of, on topics related to sexuality and prevention of HIV/AIDS. The goal of this team was to describe the diverse factors and dynamics that influence the process of recruitment and retention when conducting research. The process of recruitment entails not only the action but the planning of the interventions with both the community and the participants. Minority women and the HIV positive population have many difficulties complying with study procedures such as attendance and transportation, among other issues. We describe the importance of constant communication with the centers' coordinators and prospective participants about the process of planning and recruiting. The significance of flexibility within the research team and recognizing the particular characteristics of conducting research with minorities and women with and without HIV+ status should be emphasized. Researchers should recognize that many of the HIV+ women have been exposed to previous studies. In addition, the general population should be informed about the importance of participating in research studies.

With many parts of the world seeing an aging cohort of people living with HIV (PLHIV), it is becoming clear that some organ systems in these individuals are at a greater risk of disease. There are effects on sexual functioning in aging PLHIV, with many studies finding higher levels of sexual dysfunction in HIV-positive individuals compared with those who are HIV-negative. HIV itself, along with antiretroviral agents, may cause dysfunction. Treatment involves making an assessment of the dysfunction and using the usual methods available, although treatment may be complicated by hormonal deficiencies in HIV-positive individuals, along with the effects of antiretroviral therapy, and drug interactions involving such medications. Furthermore, the issue of HIV transmission needs to be addressed in those seeking treatment for sexual dysfunction.

To determine the prevalence, types and correlates of intimate partner violence (IPV) in pregnant Nigerian living with HIV. Cross sectional study. HIV positive pregnant women. A large HIV comprehensive treatment centre. A cross sectional study of 652 HIV positive pregnant Nigerians seen at Nigerian Institute of Medical Research, Lagos, Nigeria over a 24 months period. Prevalence of intimate partner violence after HIV diagnosis. Among the women interviewed, 423 (65.8%) reported abuse. In 74.0% of abused women, the abuse started after HIV diagnosis. Though having a HIV negative spouse and disclosure of HIV status were associated with abuse, only having a HIV negative partner retained its association with IPV (OR 3.1; CI 2.4-5.3) after controlling for confounding variables. Sixty-two (9.6%) women have not disclosed their HIV status because of fear of rejection. Verbal abuse (51.7%), threat of violence in 97 (22.9%) and sexual deprivation in 91 (21.5%) were the common forms of abuse reported. IPV is common among HIV positive pregnant Nigerians; with a threefold increased risk in women in HIV serodiscordant relationship.

Newly immigrated persons, whatever their origin, tend to fall in the lower socioeconomic levels. In fact, failure of an asylum application renders one destitute in a large proportion of cases, often resulting in a profound lack of access to basic necessities. With over a third of HIV positive failed asylum seekers reporting no income, and the remainder reporting highly limited resources, poverty is a reality for the vast majority. The purpose of the study was to determine the basic social processes that guide HIV positive undocumented migrant's efforts to gain health services in the UK. The study used the Grounded Theory Approach. Theoretical saturation occurred after 16 participants were included in the study. The data included reflections of the prominent factors related to the establishment of a safe and productive life and the ability of individuals to remain within the UK. The data reflected heavily upon the ability of migrants to enter the medical care system during their asylum period, and on an emerging pattern of service denial after loss on immigration appeal. The findings of this study are notable in that they have demonstrated sequence of events along a timeline related to the interaction between the asylum process and access to health-related services. The results reflect that African migrants maintain a degree of formal access to health services during the period that they possess legal access to services and informal access after the failure of their asylum claim. The purpose of this paper is to examine the basic social processes that characterize efforts to gain access to health services among HIV positive undocumented African migrants to the UK. The most recent estimates indicate that there are a total of 618,000 migrants who lack legal status within the UK. Other studies have placed the number of undocumented migrants within the UK in the range of 525,000-950,000. More than 442,000 are thought to dwell in the London metropolitan area. Even in

Background While most HIV care is provided on an outpatient basis, hospitals continue to treat serious HIV-related admissions, which is relatively resource-intensive and expensive. This study reports the primary reasons for HIV-related admission at a regional, urban hospital in Johannesburg, South Africa and estimates the associated lengths of stay and costs. Methods and Findings A retrospective cohort study of adult, medical admissions was conducted. Each admission was assigned a reason for admission and an outcome. The length of stay was calculated for all patients (N = 1,041) and for HIV-positive patients (n = 469), actual utilization and associated costs were also estimated. Just under half were known to be HIV-positive admissions. Deaths and transfers were proportionately higher amongst HIV-positive admissions compared to HIV-negative and unknown. The three most common reasons for admission were tuberculosis and other mycobacterial infections (18%, n = 187), cardiovascular disorders (12%, n = 127) and bacterial infections (12%, n = 121). The study sample utilized a total of 7,733 bed days of those, 55% (4,259/7,733) were for HIV-positive patients. The average cost per admission amongst confirmed HIV-positive patients, which was an average of 9.3 days in length, was $1,783 (United States Dollars). Conclusions Even in the era of large-scale antiretroviral treatment, inpatient facilities in South Africa shoulder a significant HIV burden. The majority of this burden is related to patients not on ART (298/469, 64%), and accounts for more than half of all inpatient resources. Reducing the costs of inpatient care is thus another important benefit of expanding access to ART, promoting earlier ART initiation, and achieving rates of ART retention and adherence. PMID:26885977

Rheumatic manifestations in HIV are common and sometimes the initial presentation of the disease. HIV is now a common infection at the Infectious Disease Clinic, Mulago. The spectrum of joint diseases seen depend on a number of factors such as, the CD4 count, HLA status and current therapy. This study included HIV patients from a heterogeneous population and was designed to determine the prevalence and clinical pattern of rheumatic manifestations among these HIV patients. Four hundred eighty seven patients were screened and 300 HIV positive patients were consecutively recruited into the study, evaluated for rheumatic manifestations and their clinical and laboratory findings documented. The prevalence of rheumatic manifestations was 27% (81 of 300). Arthralgias in 19.3% of the study population were commonest finding followed by HIV associated arthritis at 4.3%. The lower limbs were the most commonly affected with the knees (28.8%) and ankles (26.9%) contributing the highest. All patients had a negative anti-nuclear antibody test, with only two having a positive rheumatoid factor test. An association of antituberculosis drugs with joint disease was further highlighted in this study (OR 3.79 95% CI, 1.44 - 9.93). Septic arthritis due to Staphylococcus aureus was rarely observed except when the patients' level of CD4 + T cells dropped below 200 cells mm(3). The mean CD4+ count was 171 cells mm(3). Rheumatic manifestations should be considered among HIV positive adults. Arthralgias are common especially in patients using pyrazinamide.
Objective. The role of health professionals in the decision making process of patients is usually heard or seen from the perspective of the patients. This paper gives the usually silent and invisible health professionals voice and visibility. It describes their views and attitudes towards reproduction by couples who are HIV positive and attempts to understand their perspectives. Methods. In-depth interviews were conducted with twelve health professionals at an opportunistic infections clinic. Transcribed interviews were analysed using the grounded approach to identify patterns and themes concerning views and attitudes of health professionals towards reproduction by HIV positive people. Results. The study found that most health professionals generally had a negative attitude towards childbearing by HIV positive couples. Their views and approaches on the issue were based mainly on biomedical considerations. The main discourses on childbearing that emerged from the study were the conditional choice, the antichildbearing, and the prorights. Conclusion. Most of the health professionals interviewed tend to take a generally negative stance towards reproduction by people with HIV/AIDS. There is a need for a clear set of guidelines for health professionals (HPs) on how to deal with HIV positive people who may desire to reproduce. PMID:27350998

The use of complementary and alternative medicine (CAM) to treat chronic illnesses, especially HIV, is becoming increasingly widespread. Given this popularity, it is critical to understand how HIV-positive individuals use CAM and, more specifically, whether CAM use impacts their adherence to prescribed antiretroviral regimens (HAART). The present study examined the relationship between CAM use and HAART adherence among HIV+ women. Data were analysed from 366 HIV-positive, mostly African-American women, aged 18-50 years in Alabama and Georgia who were enrolled in an intervention to reduce high-risk sexual behaviour. At enrollment data were collected describing use of CAM and HAART use. Women were classified as CAM users if they reported taking herbal/natural immunity boosters (Chinese herbs, mushrooms, garlic, ginseng or algae) or multivitamins, or reported using religious/psychic health or bodywork to treat HIV. Women were classified as non-adherent if they reported missing any doses of their HAART medication in the 30 days preceding baseline assessment. Logistic regressions models, adjusted for potential confounders, were used to investigate the relationship between CAM use and HAART adherence. Women using CAM (immunity boosters or vitamins), relative to non-CAM users, were 1.69 times more likely to report missing HAART doses in the last 30 days (CI: 1.02-2.80; P=.041) even after adjusting for age, education, race, religion and income. The findings provide preliminary evidence that patients using CAM may be doing so as an alternative to traditional medicine as opposed to complementing prescribed HARRT treatment regimens. The inconsistent use of HAART is problematic given its association with drug resistance. Therefore, health care providers and patients should have explicit dialogues about how to effectively integrate CAM practices into traditional treatment regimens so that the safety and health of HIV-positive patients is not compromised.

Efforts to eliminate mother-to-child transmission of HIV in Tanzania are guided by a four-prong strategy advocated by the World Health Organization (WHO). Prong 2, prevention of unintended pregnancies among women living with HIV, has, however, received the least attention and contraceptive use to prevent unintended pregnancies remains low. This study explored the perceived barriers to the use of modern methods of contraception, and factors influencing contraceptive choice among HIV-positive women in urban Dar-es-Salaam, Tanzania. A qualitative multi-site study was conducted, utilising in-depth interviews and focus group discussions with 37 sexually active HIV-positive women aged between 20 and 44 years, attending three health facilities within Dar-es-Salaam. The theoretical framework was a patient centred model. Four barriers were identified: the influence of the women's spousal relationships; personal beliefs and the relationship of these in understanding her disease; the influence of the social demands on the woman and her relationships; and the importance of a woman's relationship with her healthcare provider/healthcare system. Being the bearers of bad news (HIV-positive status) the pregnant women experienced conflicts, violence, abandonment and rejection. The loss in negotiating power for the women was in relation to their intimate partners, but also in the patient-healthcare provider relationship. The role of the male partner as a barrier to contraceptive use cannot be understated. Therefore, the results suggest that healthcare providers should ensure patient-focused education and provide support that encompasses the importance of their relationships. Additional research is required to elucidate the functional association between contraceptive choices and personal and social relationships.

We describe the case of a young HIV-positive man on effective HAART with excellent viro-immunological control who presented a massive cardiac infarction. Despite the presence of clinical risk factors for cardiovascular disease, the patient had normal arterial carotid IMT values, known to be strong predictors of atherosclerosis and stroke. Interestingly, parameters of T-cell activation (CD8+CD38+) were shown to increase just before the onset of myocardial infarction. As T-cell activation is known to mediate atherosclerosis, the authors suggest that surrogate immunologic markers should be identified to better assess cardiovascular risk in the setting of HIV infection.
