    A high proportion of HIV-infected pregnant women present pathogenic organisms in their lower genital tract. This has been associated with the development of postpartum morbility, HIV transmission to the partner and offspring, and other gynaecological conditions, such as cervical dysplasia or cancer. Vaginal flora alterations can range from 47% in Western countries to 89% in Africa in pregnant HIV-positive patients, much higher than about 20% of the general population. Pathogen organism retrieval is high. As peripartum complications due to vaginal infections seem higher in HIV-positive patients, accurate investigation and treatment of such infections are strongly mandatory. PMID:22675241

    Burkitt's lymphoma is an aggressive form of Non-Hodgkin's lymphoma composed of malignant cells of B lymphocyte origin. Burkitt's lymphoma is a rarity in the Indian subcontinent. Though intraoral Burkitt's lymphoma in HIV positive individuals is very uncommon, its importance lies in the fact that it is often the first sign of the underlying immunosuppression. We present a case of Burkitt's lymphoma in right maxillary region which was the first manifestation of HIV in the patient. PMID:23188938

    HIV infection is a relative contraindication for allergic immunotherapy (AIT). In the last decade, highly active antiretroviral therapy (HAART) has improved the immune function and life expectancy in HIV-infected patients whose respiratory allergic incidence is similar to the general population. We evaluated the safety and clinical effectiveness of sublingual immunotherapy in a group of grass pollen-allergic HAART-treated HIV-positive patients. Thirteen patients received sublingual immunotherapy (SLIT) tablet (Oralair, Stallergenes©) and symptomatic therapy and were compared with nine patients receiving symptomatic therapy alone. Clinical benefits were evaluated by the analysis of total combined score (TCS), sum of symptom-medication score, and a quality of life (QoL) questionnaire. HIV viral load and peripheral TCD4 lymphocytes were analyzed at the beginning and at the end of the study. Clinical efficacy data showed a significant improvement in SLIT-treated patients compared to controls (TCS: P = 0.0001; QoL: P = 0.03). We did not observe any significant alteration of TCD4 cell counts and viral load (VL) in both groups. Our preliminary data showed that SLIT therapy in viro-immunological controlled HAART treated HIV positive patients was efficacious, safe and well tolerated. PMID:26228482

    AIMS: To describe the microscopic appearance of adenovirus infection in the large bowel of human immunodeficiency virus (HIV) positive patients with diarrhoea. METHODS: Large bowel biopsy specimens from 10 HIV positive patients, eight of whom were also infected with other gastrointestinal pathogens, with diarrhoea were examined, together with six small bowel biopsy specimens from the same group of patients. Eight of the patients had AIDS. The biopsy specimens were examined by light microscopy performed on haematoxylin and eosin stained and immunoperoxidase preparations, the latter using a commercially available antibody (Serotec MCA 489). Confirmation was obtained with electron microscopy. RESULTS: The morphological appearance of cells infected with adenovirus showed characteristic nuclear and cellular changes, although the inflammatory reaction was non-specific. Immunoperoxidase staining for adenovirus was sensitive and specific, and the presence of viral inclusions consistent with adenovirus was confirmed by electron microscopy. CONCLUSIONS: The light microscopic features of adenovirus infection are distinctive and immunocytochemistry with a commercially available antibody is a sensitive and specific means of confirming the diagnosis. Further studies of the role of adenovirus in causing diarrhoea in these patients are indicated. Images PMID:1401177

    Abdominal pain is a frequent presenting symptom among HIV-positive patients seeking care at emergency departments. We report a case of a 45-year-old HIV-infected Hispanic man who presented with right lower quadrant pain accompanied by fever, decreased appetite, nausea, and vomiting. The results of a CT scan of his abdomen were normal with no evidence of appendicitis. A colonoscopy was performed and revealed an impacted pill in the appendiceal orifice. The pill was removed endoscopically, and pill impaction has not recurred. PMID:19209455

    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.

    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. PMID:24492851

    The clinical management of cervical cancer in HIV-positive patients has challenges mainly due to the concerns on immune status. At present, their mode of management is similar to HIV-seronegative patients involving the use of chemotherapy and radiotherapy concurrently as indicated. HIV infection, cancer, radiotherapy, and chemotherapy lower immunity through reduction in CD4 cell counts. At present there are no treatment guidelines for HIV-positive patients. This study was done to systematically review the literature on cervical cancer management in HIV-positive patients and treatment outcomes. A systematic literature search was done in the major databases to identify studies on the management of HIV-positive patients with cervical cancer. Identified studies were assessed for eligibility and inclusion in the review following the guidelines of The Cochrane Handbook for Systematic Reviews and CRD's (Centre for Reviews and Dissemination) guidance for undertaking reviews in health care. Eight eligible studies were identified from the literature. Three of them were prospective while five were retrospective studies. Notably, the average age at diagnosis of cervical cancer in HIV-positive patients was a decade lower than in seronegative patients. There was no difference in distribution of stages of disease at presentation between HIV-positive and negative patients. Mild acute toxicity (Grades 1 and 2) was higher in HIV-positive patients than in HIV-negative patients in hematopoietic system. In the grades 3 and 4 reactions, anemia was reported in 4% versus 2% while gastrointestinal reactions were reported in 5% versus 2% respectively. In general, patients who were started early on HAART had higher rates of treatment completion. The study supports the suggestion that HAART should be commenced early at cervical cancer diagnosis in HIV-positive patients diagnosed with cervical cancer to ensure less toxicity and better treatment compliance.

    We describe the case of a HIV-positive patient treated for visceral leishmaniasis who developed uveitis as part of a leishmaniasis immune reconstitution syndrome. Visceral leishmaniasis is increasingly found in HIV-positive adults. Its ophthalmic manifestations can range from relatively minor to complicated anterior uveitis, leading to secondary glaucoma and loss of vision. Clinicians caring for people living with HIV should be alert to the complications of leishmaniasis that can occur before and during treatment. PMID:26002317

    The African-American community has been disproportionately affected HIV/AIDS, as noted by higher reported rates of HIV infection, higher proportion of AIDS cases, and more deaths caused by complications of AIDS than whites and other ethnic groups. In addition, epidemiologic trends suggest that African Americans with HIV infection are more often diagnosed later in the course of HIV disease than whites. Numerous reasons account for this disparity, including the lack of perception of risk and knowledge about HIV transmission as well as a delays in HIV testing and diagnosis in the African-American community. Understanding the important considerations in the management of HIV infection in the African-American patient may create awareness among health care professionals and broaden the knowledge of HIV-infected patients within the African-American community.

    We describe a hypothetical case of an HIV-positive dentist without cognitive impairment who uses proper infection control procedures. The dentist's physician notifies the medical officer of health without the dentist's consent. Although HIV-positive health care workers, including dentists, have been identified in the past, proven HIV transmission to patients is very rare. Most authorities recommend that an HIV-positive health care worker be monitored by an expert panel, which could then, if necessary, refer to the regulatory body to revoke or restrict the person's license to practice. Mandatory HIV testing is not required for health care workers because they generally do not pose a risk for infecting their patients; they are, however, ethically and legally obligated to report their HIV status to their profession's regulatory body.

    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. PMID:25631478

    Background Emerging evidence suggests differences in colo-rectal cancer in HIV-infected patients (HIV+) compared with HIV− patients. Microsatellite instability (MSI), occurring in a subset of colorectal cancer, is present at a higher rate in certain cancers in HIV+ patients. Colorectal cancer with MSI share some characteristics with those reported for HIV+ colorectal cancer. On this premise, we studied clinical and pathologic features of HIV+ colorectal cancer and evaluated for MSI using matched HIV− colorectal cancer controls. Methods Two nested, matched cohorts were identified from a hospital-based cohort of colorectal cancer patients. HIV+ colo-rectal cancers were identified and random control patients were matched for selected characteristics. Mismatch repair protein (MMR) IHC was performed as the detection method for MSI. Variables were compared between cases and controls using fixed-effects logit modeling to account for matching. Results We included 184 colorectal cancer samples (38 HIV+, 146 HIV− control). Median patient age at colorectal cancer onset was 55. When compared with HIV− colorectal cancer, HIV+patients were more likely to have smoked (P = 0.001), have right-sided colorectal cancer (37% vs. 14%; P = 0.003), and tumor-infiltrating lymphocytes (TIL) above 50/10 high-power fields (21% vs. 7%). There was no difference in MMR protein expression (P = 0.6). HIV+ colorectal cancer patients had reduced overall survival (P = 0.02) but no difference in progression-free survival. Conclusions HIV+ patients developed colorectal cancer at a lower median age than population estimates, had a higher frequency of right-sided disease, and increased TILs, suggesting potential biologic differences compared with uninfected patients. Impact Clinicopathologic differences in colorectal cancer of HIV+ persons may have implications for tumor pathogenesis. PMID:27197294

    2016-07-01

    Hepatitis E virus (HEV) is a RNA virus that can cause hepatitis. In immunocompetent individuals, infection with HEV usually leads to asymptomatic seroconversion. However, in immunosuppressed patients, such as transplant recipients, HEV can develop into a chronic infection. Studies regarding the seroprevalence and clinical implications of HEV in patients infected with the human immunodeficiency virus (HIV) are conflicting. Levels of CD4 count in blood seem to be the most widely associated risk factor, while other factors such as meat consumption or proximity to animals are less clearly associated with HEV infection. Progression to chronicity, as well as extrahepatic manifestations of HEV seem rare in HIV, and the implications of HEV in liver disease progression are poorly understood in the HIV-infected. In this review we describe the epidemiology, risk factors, and clinical implications of HEV infection in individuals infected with HIV. PMID:27243210

    Objective To identify the frequency of syphilis among Iranian HIV-positive patients. Methods A cross-sectional study on the prevalence of syphilis and HIV co-infection among 450 patients diagnosed with HIV infection was conducted between 2004 and 2008 at Imam Khomeini hospital, Tehran, Iran. The lab tests including CD4 cell count, cerebrospinal fluid, veneral disease research laboratory (VDRL), fluorescent treponema antibody-absorption (FTA-Abs) and viral load were performed for all the patients. Data regarding medical history and their demographics were also collected. Results Of all 450 HIV-positive patients, 24 (5.3%) had a positive VDRL test and only two men had a FTA-Abs positive test which means 0.45% of them had a definite co-infection of syphilis. 65.3% of the HIV-positive patients were injection drug users that the co-infection prevalence of them was 0.7%. We did not find any patient with neurosyphilis. Conclusions Considering the increasing prevalence of HIV and also extensive use of highly active antiretroviral therapy in developing nations, the diagnosis of syphilis should be timely established using screening tests among such patients.

    Most countries exclude human immunodeficiency virus (HIV)-positive patients from organ donation because of concerns regarding donor-derived HIV transmission. The Swiss Federal Act on Transplantation has allowed organ transplantation between HIV-positive donors and recipients since 2007. We report the successful liver transplantation from an HIV-positive donor to an HIV-positive recipient. Both donor and recipient had been treated for many years with antiretroviral therapy and harbored multidrug-resistant viruses. Five months after transplantation, HIV viremia remains undetectable. This observation supports the inclusion of appropriate HIV-positive donors for transplants specifically allocated to HIV-positive recipients. PMID:27109874

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

    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. PMID:22783004

    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

    OBJECTIVES: To determine the extent of fertility desires and intentions of HIV-positive patients receiving care at a suburban specialist clinic and assess how these may vary by their sociodemographic and health-related factors. METHODS: Questionnaire-based interview of a consecutive sample of HIV-positive men (18-55 years) and HIV-positive women (18-45 years) who presented at the HIV clinic of the Center for Special Studies, Sagamu, Nigeria, between November and December 2004. RESULTS: 63.3% of the 147 studied participants expressed the desire for childbearing, even though 50.4% of them already had > or = 2 children. Respectively, 71.5% and 93.8% of men and women who desired children intended to have > or = 2 in the near future. Only 4.3% of those who desired children did not intend to have any. All 30 individuals who had no children intended to bear children in the future, and they constituted 32.3% of those who expressed the desire for childbearing. Multivariate logistic regression analyses of associated factors indicated that decreasing age, shorter time since diagnosis of HIV infection and nondisclosure of serostatus to current partner significantly increase the odds of desire for childbearing, while having no children and a poor most-recent CD4 count significantly increase the odds of intention to have > or = 3 children instead of 1-2. CONCLUSION: The extent of the fertility desires and intentions of these patients poses a threat to the preventive strategies against vertical and heterosexual transmission of HIV in this region. In view of their compelling desire for parenthood, it may be wise for caregivers to desist from the conventional systematic advice against pregnancy but, in addition to laying emphasis on the risks, provide adequate information on practicable reproductive options for HIV-positive individuals.

    Objectives Tenofovir disoproxil fumarate (TDF) may cause renal tubular dysfunction (RTD) and reduce bone mineral density (BMD). We examined the relationship between RTD and BMD in TDF-exposed HIV-positive men. Design and methods We analysed urinary retinol binding protein/creatinine ratio (RBPCR) and fractional excretion of phosphate (FEPO4) to quantify RTD in a cross sectional sample of randomly selected HIV positive men at a single tertiary outpatient clinic. BMD at the lumbar spine and hip was measured by dual-energy x-ray absorptiometry. Multivariate logistic regression was used to analyse factors associated with RTD, and linear regression to examine the relationship between RTD and BMD. Results Of 293 men (mean age 48 years, 94% white ethnicity, median TDF exposure 2.1 years), 22.5% had RBPCR-defined RTD and 12.3% had FEPO4-defined RTD. We observed a negative correlation between RBPCR and BMD at the spine (β -0.2, p=0.002) and hip (total: β -0.1, p=0.02; femoral neck: β -0.1, p=0.02), but not between FePO4 and BMD. In multivariable analyses, RTD defined by >5 fold elevations in RBPCR was associated with significantly lower BMD of the spine. Conclusions RTD was associated with lower BMD of the spine in HIV-positive men. RBPCR quantification may identify patients at increased risk of TDF-associated BMD reduction. PMID:26372384

    Neurocognitive impairment (NCI) is frequently observed in patients infected with human immunodeficiency virus (HIV) and results from the compromise of subcortical brain structures by the virus. The manifestations of NCI range from asymptomatic impairment to dementia. In addition to cognitive impairment resulting from HIV infection, other factors such as depression are associated with the loss of cognitive functions. The aim of this study was to estimate the prevalence of NCI in HIV-positive patients in a city in southern Brazil and to establish possible associations for the prevalence of NCI with HIV-related and other risk factors. This cross-sectional study of HIV-positive outpatients was conducted in a specialized care service in the city of Pelotas in Southern Brazil. Sociodemographic data and HIV-related information were collected, and all patients underwent psychiatric and neurocognitive evaluations. The prevalence of NCI among the 392 patients was 54.1% when tracked using the IHDS (International HIV Dementia Scale) and 36.2% when the IHDS was associated with a battery of complementary tests. A bivariate analysis suggested an association of NCI with gender, age, educational level, depression, current CD4 count and lowest CD4 count. The association of NCI with depression remained in the Poisson regression (PR=1.96, 95%CI=1.12-3.42). The prevalence of cognitive impairment in HIV-positive patients estimated in this study is in accordance with international and Brazilian data. Of the factors analyzed, depression showed the greatest evidence of association with neurocognitive loss. Based on our findings, the inclusion of instruments to evaluate depression in our services for patients with HIV and acquired immunodeficiency syndrome (AIDS) is recommended. PMID:27626305

    Non-Hodgkin's lymphoma (NHL) is seldom seen in the oral cavity, and has been reported with some frequency in HIV-positive patients. Oral HIV-related lymphomas exhibit an aggressive course and can mimic other oral tumors and infections that make early recognition and diagnosis difficult. This paper presents a case of NHL on the gingiva of a 28-year-old HIV-positive male patient. PMID:23225984

    macrolide resistance mutation (A2058G). In subgroup analyses confined to the 75 patients infected with T. pallidum lacking resistance mutation, a statistically significantly lower risk for the Jarisch-Herxheimer reaction following azithromycin treatment was noted. Conclusions Treatment with azithromycin was associated with a lower risk for the Jarisch-Herxheimer reaction than that with benzathine penicillin G in HIV-positive patients with early syphilis. Previous benzathine penicillin G therapy for syphilis decreased the risk, whereas higher RPR titres increased the risk, for the reaction. PMID:25174641

    The case of a 33-year-old HIV-positive patient who suffered from second- and third-degree burn injuries involving 30% of the body surface is reported. She was treated by early tangential excision of the burnt skin and split-thickness mesh grafting. The burn wounds healed without complications within the usual time, with excellent cosmetic and functional results. In spite of the successful treatment, she suffered from fever and various infections for several months. With the appearance of these constitutional symptoms, we recognized the AIDS-related complex. Her general condition deteriorated continuously and 10 months after the accident she had to be admitted to a hospital again. The skin had nevertheless healed perfectly and in spite of not having compression treatment for the grafts or physiotherapy, she did not show any signs of hypertrophic scars. Some important conclusions drawn from this case are discussed. The fact that healing occurred without complications is in contrast to the results reported in the literature concerning impaired wound healing in AIDS patients with anorectal surgery. We therefore believe that the reluctant and perhaps even anxious attitude of the medical and nursing staff towards performing technical and expensive procedures in HIV-positive burn patients is not justified.

    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

    Buruli ulcer is a chronic and infectious skin disease, caused by Mycobacterium ulcerans. It leads to large skin ulceration and sometimes bone infection which is responsible for deformities. Here, we report a case of multifocal form of Buruli ulcer associated with secondary infection in a 46-year-old human immunodeficiency virus (HIV) positive woman. The antimycobacterial drugs combined to surgery allowed curing this multifocal case and rose up two relevant issues: the susceptibility of immune reconstitution inflammatory syndrome (IRIS) occurrence and Mycobacterium dissemination. The deep immune depression, the underline biological, and clinical disorders of the patient might contribute to IRIS occurrence and Buruli ulcer dissemination. Future investigations have to be conducted on the mechanism of IRIS on set and on Mycobacterium ulcerans dissemination after ARV drugs initiation and the patient related underline clinical or biological disorders.

    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.

    Over the past decade there have been several reports in the literature of atypical forms of granuloma annulare (GA) occurring in HIV positive patients. We now report a case of diffuse granuloma annulare in an HIV positive patient with unusual clinical and immunohistological features. Our patient presented with a persistent extensive macular erythematous eruption on his face and upper trunk with bizarre sparing around the nipples and axillae. The histology showed an interstitial pattern of GA, with a predominance of CD8 positive cells, in contrast to the usual CD4 positive infiltrate typically seen in GA. PMID:12072009

    The microscopic observation drug susceptibility assay (MODS) is a novel and promising test for the early diagnosis of tuberculosis (TB). We evaluated the MODS assay for the early diagnosis of TB in HIV-positive patients presenting to Pham Ngoc Thach Hospital for Tuberculosis and Lung Diseases in southern Vietnam. A total of 738 consecutive sputum samples collected from 307 HIV-positive individuals suspected of TB were tested by smear, MODS, and the mycobacteria growth indicator tube method (MGIT). The diagnostic sensitivity and specificity of MODS compared to the microbiological gold standard (either smear or MGIT) were 87 and 93%, respectively. The sensitivities of smear, MODS, and MGIT were 57, 71, and 75%, respectively, against clinical gold standard (MODS versus smear, P < 0.001; MODS versus MGIT, P = 0.03). The clinical gold standard was defined as patients who had a clinical examination and treatment consistent with TB, with or without microbiological confirmation. For the diagnosis of smear-negative patients, the sensitivities of MODS and MGIT were 38 and 45%, respectively (P = 0.08). The median times to detection using MODS and MGIT were 8 and 11 days, respectively, and they were 11 and 17 days, respectively, for smear-negative samples. The original bacterial/fungal contamination rate of MODS was 1.1%, while it was 2.6% for MGIT. The cross-contamination rate of MODS was 4.7%. In conclusion, MODS is a sensitive, specific, and rapid test that is appropriate for the detection of HIV-associated TB; its cost and ease of use make it particularly useful in resource-limited settings.

    The aim of this investigation was to identify factors associated with HIV transmission risk behavior among HIV-positive women and men receiving antiretroviral therapy (ART) in KwaZulu-Natal, South Africa. Across 16 clinics, 1,890 HIV+ patients on ART completed a risk-focused audio computer-assisted self-interview upon enrolling in a prevention-with-positives intervention trial. Results demonstrated that 62 % of HIV-positive patients’ recent unprotected sexual acts involved HIV-negative or HIV status unknown partners. For HIV-positive women, multivariable correlates of unprotected sex with HIV-negative or HIV status unknown partners were indicative of poor HIV prevention-related information and of sexual partnership-associated behavioral skills barriers. For HIV-positive men, multivariable correlates represented motivational barriers, characterized by negative condom attitudes and the experience of depressive symptomatology, as well as possible underlying information deficits. Findings suggest that interventions addressing gender-specific and culturally-relevant information, motivation, and behavioral skills barriers could help reduce HIV transmission risk behavior among HIV-positive South Africans.

    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

    Lymphoma should be considered early in patients with HIV when there is a history of weight loss. Although B-cell lymphoma is an AIDS-defining cancer, and many reports of lymphoma in HIV positive patients exist in the literature, this case report illustrates that even in patients with well-controlled HIV the diagnosis must be considered, and puts forward an unusual presentation in an otherwise asymptomatic patient. A 52 year old woman presented for a routine HIV follow-up appointment and was found to be experiencing weight loss. An abdominal examination revealed a right iliac fossa mass. Subsequent CT thorax, abdomen, pelvis imaging confirmed a large mass but did not allow determination of the primary source. Serological tumour marker investigations were unyielding. Trans-vaginal ultrasound guided biopsy of the mass demonstrated diffuse large B-cell lymphoma. This case report emphasises the importance of having a high index of suspicion for these cancers even in patients with low viral load who are on anti-retroviral treatment. It also demonstrates the importance of taking a multidisciplinary approach to diagnosis of the condition to enable prompt treatment and thus improve the outcome for the patient. PMID:26971281

    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).

    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

    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

    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.

    BACKGROUND Elderly people present alterations in body composition and physical fitness, compromising their quality of life. Chronic diseases, including HIV/AIDS, worsen this situation. Resistance exercises are prescribed to improve fitness and promote healthier and independent aging. Recovery of strength and physical fitness is the goal of exercise in AIDS wasting syndrome. OBJECTIVE This study describes a case series of HIV-positive elderly patients who participated in a progressive resistance training program and evaluates their body composition, muscular strength, physical fitness and the evolution of CD4+ and CD8+ cell counts. METHODS Subjects were prospectively recruited for nine months. The training program consisted of three sets of 8–12 repetitions of leg press, seated row, lumbar extension and chest press, performed with free weight machines hts, twice/week for one year. Infectious disease physicians followed patients and reported all relevant clinical data. Body composition was assessed by anthropometric measures and dual-energy x-ray absorptiometry before and after the training program. RESULTS Fourteen patients, aged 62–71 years old, of both genders, without regular physical activity who had an average of nine years of HIV/AIDS history were enrolled. The strengths of major muscle groups increased (74%–122%, p=0.003–0.021) with a corresponding improvement in sit-standing and walking 2.4 m tests (p=0.003). There were no changes in clinical conditions and body composition measures, but triceps and thigh skinfolds were significantly reduced (p=0.037). In addition, there were significant increases in the CD4+ counts (N=151 cells; p=0.008) and the CD4+/CD8+ ratio (0.63 to 0.81, p=0.009). CONCLUSION Resistance training increased strength, improved physical fitness, reduced upper and lower limb skinfolds, and were associated with an improvement in the CD4+ and CD4+/CD8+ counts in HIV positive elderly patients without significant side effects.

    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. Conclusions This spectroscopic study revealed a significantly lower N-acetyl-aspartate in the white matter in a frontal and parietal cerebral target region in asymptomatic, HIV-positive

    Histoplasmosis is usually an opportunistic fungal infection in patients with defective cell mediated immunity, and has been considered as one of the acquired immunodeficiency syndrome (AIDS) defining illness. However, cutaneous involvement in human immunodeficiency virus (HIV) positive patients is less common, and very rarely can be the initial presenting symptom for the diagnosis of AIDS. We present here an unusual case of multiple diffuse cutaneous nodular lesions predominantly in face, trunk, and upper extremities diagnosed initially on aspiration cytology as histoplasmosis. Subsequent serological test revealed positivity for HIV 1 and 2, along with a low CD4 count and low CD4:CD3 ratio. The cytomorphological features were further corroborated by histology and histochemical stains. Hence, cutaneous histoplasmosis can cause multiple wide spread nodular or umbilicated lesions in AIDS patients as the initial presentation. Fine needle aspiration cytology (FNAC) is a rapid, cost effective tool for diagnosis of the fungi from such lesions and initiating work up for immunocompromised states including AIDS. PMID:21987498

    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.

    Considerable progress has been made in the provision of life-saving antiretroviral therapy (ART) for persons with human immunodeficiency virus (HIV) infection worldwide, resulting in an overall decrease in HIV incidence and acquired immunodeficiency syndrome (AIDS)-related mortality. In the strategic scale-up of HIV care and treatment programs, persons with HIV and tuberculosis (TB) are a priority population for receiving ART. TB is the leading cause of death among persons living with HIV in sub-Saharan Africa and remains a potential risk to the estimated 35 million persons living with HIV globally. Of the 9 million new cases of TB disease globally in 2013, an estimated 1.1 million (13%) were among persons living with HIV; of the 1.5 million deaths attributed to TB in 2013, a total of 360,000 (24%) were among persons living with HIV. ART reduces the incidence of HIV-associated TB disease, and early initiation of ART after the start of TB treatment reduces progression of HIV infection and death among HIV-positive TB patients. To assess the progress in scaling up ART provision among HIV-positive TB patients in 19 countries in sub-Saharan Africa with high TB and HIV burdens, TB and HIV data collected by the World Health Organization (WHO) were reviewed. The results found that the percentage of HIV-positive TB patients receiving ART increased from 37% in 2010 to 69% in 2013. However, many TB cases among persons who are HIV-positive go unreported, and only 38% of the estimated number of HIV-positive new TB patients received ART in 2013. Although progress has been made, the combination of TB and HIV continues to pose a threat to global health, particularly in sub-Saharan Africa. PMID:25426652

    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

    Objective Identify and analyze the factors associated to length of hospital stay among HIV positive and HIV negative patients with tuberculosis in Manaus city, state of Amazonas, Brazil, in 2010. Methods Epidemiological study with primary data obtained from monitoring of hospitalized patients with tuberculosis in Manaus. Data were collected by interviewing patients and analyzing medical records, according to the following study variables age, sex, co-morbidities, education, race, income, lifestyle, history of previous treatment or hospitalization due to tuberculosis, treatment regimen, adverse reactions, smear test, clinical form, type of discharge, and length of hospital stay. The associated factors were identified through chi-square or t-Student test at a 5% significance level. Results Income from 1 to 3 minimum wages (P = 0.028), pulmonary tuberculosis form (P = 0.011), negative smear test or no information in this regard (P = 0.014), initial 6-month treatment scheme (P = 0.029), and adverse drug reactions (P = 0.021) were associated to prolonged hospital stay in HIV positive patients. Conclusion We found out that although there were no significant differences in the length of hospital stay in HIV positive patients, all factors significantly associated to prolonged hospital stay occurred in this group of patients. This finding corroborates other studies indicating the severity of tuberculosis in HIV patients, which may also contribute to lengthen their hospital stay. PMID:23593227

    Knowledge of mortality trends and predictors among HIV-positive patients in the era of highly active antiretroviral therapy (HAART) in resource poor settings is still limited. The aim of this study was to describe trends and predictors of mortality among HIV-positive patients in the era of HAART in Uganda. Data from 2004 to 2013 for adult HIV-positive patients (≥15 years) obtaining care and treatment from the AIDS Support Organization in Uganda were reviewed for mortality. Descriptive statistics were analyzed by frequencies and cross tabulations. Calendar period was used as a proxy measure for HAART exposure and a time plot of the proportion of HIV-positive patients reporting dead per year was used to describe the trends. Logistic regression was used to determine the predictors of mortality at bivariate and multivariate levels, respectively. We included in the analysis 95,857 HIV positive patients; 64% were female with median age of 33 years (interquartile range 27-40). Of these 36,133 (38%) were initiated on ART and a total of 4279 (4.5%) died; 19.5% (835/4279) of those who died had an opportunistic infection. Overall, mortality first increased between 2004 and 2006 and thereafter substantially declined (X2trend=211.9, P<0.001). Mortality was relatively higher in Eastern Uganda compared to other geographical areas. Male gender, older age (>45 years), being from Eastern or Northern Uganda, having none or primary education, being unemployed, advanced immunodeficiency (CD4 count <100 cell/µL or WHO stage III or IV) and underweight (<45 kg weight) at HAART initiation and calendar period 2004-2008 were significant predictors of mortality (P<0.001). Overall, the expanding coverage of HAART is associated with a declining trend in mortality among HIV positive patients in Uganda. However, mortality trends differed significantly by geographical area and men remain potentially at higher risk of death probably because of delayed initiation on ART. There is urgent need for

    Introduction Cardiovascular risk factors are prevalent in HIV-positive patients which places them at increased risk for cardiovascular disease (CVD). We aimed to determine the risk factors and risk assessment for CVD in HIV-positive patients with and without antiretroviral therapy. Methods This was a cross-sectional study of HIV-positive patients attending the Lagos University Teaching Hospital, Nigeria. Anthropometric and blood pressure measurements were performed; fasting lipid profile, plasma glucose, homocysteine and hsCRP were determined, as well as prevalences and risk assessments. Statistical tests were used to compare the groups and p-value <0.05 was considered to be significant. Results 283 subjects were recruited for this study (100 HIV-positive treatment-naive, 100 HIV-positive treated and 83 HIV negative controls). Compared to the controls, mean (sd) values were significantly higher among HIV-treated subjects: waist circumference = 88.7 (10.4), p = 0.035; systolic bp= 124.9 (20.7), p = 0.014; glucose= 5.54 (1.7), p = 0.015; triglyceride= 2.0 (1.2), p < 0.001; homocysteine= 10.9 (8.9-16.2), p = 0.0003; while hsCRP= 2.9 (1.4-11.6), p = 0.002 and HDL-C = 0.9 (0.4), p = < 0.0001 were higher among the HIV-naïve subjects. Likewise, higher prevalences of the risk factors were noted among the HIV-treated subjects except low HDL-C (p < 0.001) and hsCRP (p = 0.03) which were higher in the HIV-naïve group. Risk assessment using ratios showed high risk for CVD especially in the HIV-naïve group. The median range for Framingham risk assessment was 1.0 - 7.5%. Conclusion Risk factors and risk assessment for CVD are increased in HIV-positive patients with and without antiretroviral therapy. Routine evaluation and risk assessment for CVD irrespective of therapy status is necessary to prevent future cardiovascular events. PMID:27347295

    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.

    This study used Olshansky's (1962) concept of chronic sorrow to examine social support needs of 21 human immunodeficiency virus (HIV)-positive men and women in a southern U.S. city. The methods of inquiry consisted of narrative interviews and a quantitative assessment of depression (the Center of Epidemiological Studies on Depression [CES-D] Scale). This combined approach indicated that chronic sorrow in HIV-positive persons is related to illness, fear of death, poverty, and social isolation, especially for women with children. More than half of the subjects scored as depressed, with African American women scoring significantly higher than Caucasian men or women. Social isolation often resulted from the effects of stigma, as framed in Erving Goffman's theory of discredited identity. The women were likely to be stigmatized because of their association with "dirty sex," contagion, and moral threat in heterosexual communities. Most of the men had been protected from the worst effects of stigma because of their ties to the gay community and associated health networks. Based on these preliminary findings, stigma should be considered a marker of chronic depression in the HIV-positive, and support services should take account of the stigmatizing contexts of HIV-positive persons.

    Depressive symptoms cause major impairment and may accelerate HIV progression despite the use of antiretroviral medication. The somatic symptoms criteria for HIV infection and depression partially overlap, which can make differential diagnosis challenging. Because of chronic inflammation caused by HIV infection, HIV-positive patients may develop somatic and affective-cognitive symptoms of depression. Inflammation-related depression is primarily characterized with severe somatic symptoms such as fatigue and sleep disturbance. This study sought to explore the patterns of somatic and cognitive-affective depressive symptoms that characterize HIV-positive patients. Our specific aims were (1) to identify subtypes of depressive symptoms in a sample of HIV-positive patients; and (2) to test the subtypes' difference on inflammatory and HIV disease progression biomarkers. HIV-positive men and women (N=102) with and without depressive symptoms were randomly selected from an Italian HIV clinic. Depressive symptoms (PHQ-9), viral load (VL), CD4+, Il-6, TNF-α, and monocytes were assessed. The three subtypes formed using Latent Class Analysis (LCA) identified patients with (1) severe cognitive-affective and somatic depressive symptoms; (2) severe/moderate somatic symptoms; and (3) absent or low depressive symptoms. The subtype with severe/moderate somatic symptoms was characterized with elevated levels of Il-6 and monocytes. No difference on HIV progression biomarkers was found. The subtypes of depressive symptoms might help differentiating depressive symptoms from HIV- and inflammatory-related somatic symptoms. When present, cognitive-affective and/or somatic symptoms cause significant impairment to patients' lives and thus warrant further assessment and treatment. PMID:26883521

    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.

    Introduction Liver disease related to hepatitis B (HBV) and hepatitis C (HCV) may temper the success of antiretroviral therapy (ART) in China. Limited data exist on their prevalence in HIV-positive Chinese. A multi-centre, cross-sectional study was carried out to determine the prevalence and disease characteristics of HBV and HCV co-infection in HIV-positive patients across 12 provinces. Methods HIV-positive ART-naïve patients were recruited from two parent cohorts established during November 2008–January 2010 and August 2012–September 2014. Hepatitis B surface antigen (HBsAg), hepatitis B e antigen and HCV antibody (anti-HCV) status were retrieved from parent databases at the visit prior to ART initiation. HBV DNA was then determined in HBsAg+ patients. HCV RNA was quantified in anti-HCV+ patients. Aspartate aminotransferase-to-platelet ratio index (APRI) and the fibrosis-4 (FIB4) were calculated. Chi-square test, Kruskal–Wallis test and logistic regression were used for statistical analysis, as appropriate. Results Of 1944 HIV-positive patients, 186 (9.5%) were HIV–HBV co-infected and 161 (8.3%) were HIV–HCV co-infected. The highest HIV–HBV prevalence (14.5%) was in Eastern China while the highest HIV–HCV prevalence was in the Central region (28.2%). HIV–HBV patients had lower median CD4 + T cell count (205 cells/μL) than either HIV monoinfected (242 cells/μL, P=0.01) or HIV–HCV patients (274 cells/μL, P=0.001). Moderate-to-significant liver disease was present in >65% of the HIV–HCV, ~35% of the HIV–HBV and ~20% of the HIV monoinfected patients. Independent associations with moderate-to-significant liver disease based on APRI included HBV (Odds ratio, OR 2.37, P < 0.001), HCV (OR 9.64, P<0.001), CD4 count≤200 cells/μL (OR 2.55, P<0.001) and age ≥30 years (OR 1.80, P=0.001). Conclusions HBV and HCV prevalence is high in HIV-positive Chinese and differs by geographic region. HBV and HCV co-infection and HIV monoinfection are risks

    While the diagnostic properties of the TB LAM urine assay (LAM) have been well-described, little is known about its predictive and prognostic properties at ART initiation in a routine clinic setting. We describe the predictive and prognostic properties of LAM in HIV-positive patients initiating ART at an urban hospital in Johannesburg, South Africa. Retrospective study of HIV-positive adults (>18 years) who initiated standard first-line ART between February 2012 and April 2013 and had a LAM test at initiation. In HIV-positive patients with no known TB at ART initiation, we assessed the sensitivity, specificity and positive/negative likelihood ratios of LAM to predict incident TB within 6 months of ART initiation. In addition, in patients with a TB diagnosis and on TB treatment <3 months at ART initiation, we measured the CD4 response at 6 months on ART. Of the 274 patients without TB at ART initiation, 65% were female with median CD4 count of 213 cells/mm3. Among the 14 (5.1%) patients who developed active TB, none were urine LAM +ve at baseline. LAM had poor sensitivity (0.0% 95% CI 0.00-23.2) to predict incident TB within 6 months of initiation. We analyzed 22 patients with a confirmed TB diagnosis at initiation separately. Of these, LAM +ve patients (27%) showed lower CD4 gains compared to LAM negative patients (median increase 103 vs 199 cells/mm3; p = 0.08). LAM has limited value for accurately predicting incident TB in patients with higher CD4 counts after ART initiation. LAM may help identify TB/HIV co-infected patients at ART initiation who respond more slowly to treatment and require targeted interventions to improve treatment outcomes. Larger studies with longer patient follow-up are needed. PMID:26600904

    In this qualitative study, 29 HIV-positive, Chinese patients reported highly favorable impressions of their healthcare providers, who were seen as providing important medical-related, financial, and emotional support. Generally, the patient-provider relationship positively impacted the participants and their ability to maintain their health and was especially critical when patients were isolated from familial sources of support due to intense AIDS stigma. Often family members were informed of an HIV diagnosis before the patient, revealing tensions between Confucian principles of collectivism and familial authority and increasingly prevalent Western ideals of individual autonomy and the privileged status of personal health information.

    The introduction of highly active antiretroviral therapy (HAART) is typically represented as a turning point in the social and medical history of HIV/AIDS, leading to a conceptual division into pre- and post-HAART eras. This paper explores how generational discourse is produced in interviews with general practitioners (GPs) and their HIV positive gay male patients in making sense of this moment and related changes in the Australian HIV epidemic. A theme of 'HIV generations' was identified in in-depth interviews with GPs who have HIV medication prescribing rights (based in Sydney, Adelaide and rural-coastal New South Wales) and the HIV positive gay men who attend their practices. In a closer analysis, generational discourse was identified across the interviews with GPs, characterising pre- and post-HAART HIV generations through three main features: treatment histories, socioeconomic status, and modes of survivorship. While generational discourse was less common in the accounts of HIV positive gay men, many of their examples wove together two narrative forms - 'a different time' and 'difference today' - suggesting that concepts of time and inequity are deeply embedded in these men's understandings of the HIV experience. Our analysis indicates that generational concepts play a significant role in shaping both professional and 'lay' understandings of changes and patterns in the HIV epidemic. PMID:20347197

    Background 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. Material and Methods 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. Results 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). Conclusions 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.

    Protease inhibitors, used as treatment in human immunodeficiency virus (HIV) infection, are associated with a syndrome of peripheral lipodystrophy, central adiposity, hyperlipidemia and insulin resistance. An HIV-positive patient with chronic obstructive pulmonary disease is presented who developed the lipodystrophy syndrome that is associated with the use of protease inhibitors. It is postulated that the lipodystrophy syndrome further compromised his lung function, leading to respiratory failure. Patients who have pulmonary disease and are taking protease inhibitors require monitoring of clinical status and pulmonary function tests. PMID:11521144

    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

    BACKGROUND--Despite the immune suppression, frequent hospital admissions, and many intercurrent illnesses associated with HIV infection, Pseudomonas aeruginosa has been cited relatively infrequently as a respiratory pathogen in HIV positive patients. METHODS--The microbiological isolates, medical records, radiographic reports, and laboratory data from 224 patients undergoing sputum induction and/or bronchoalveolar lavage for evaluation of respiratory symptoms suspicious for Pneumocystis carinii pneumonia (PCP) from 1989 to 1992 were reviewed retrospectively. RESULTS--An increasing number of respiratory isolates with Pseudomonas aeruginosa was found over this time period. Eighteen of the 224 patients were identified in whom P aeruginosa was recovered on at least one occasion. These patients were more likely to have a history of smoking and prior PCP than those in whom Pseudomonas was not recovered. Mean CD4 counts were also significantly lower in these patients. CONCLUSIONS--Pseudomonas aeruginosa may be recovered from a substantial number of respiratory isolates from HIV positive patients suspected of having PCP. The prevalence of this phenomenon may be increasing. PMID:7597670

    Visceral leishmaniasis (VL) serosurvey was carried out on 49 HIV/AIDS patients among 500 asymptomatic HIV/infected patients who registered in the Khorasan Razavi Province during the last 14 years. HIV infections were detected by ELISA and confirmed using western blot assay at the AIDS centre of the Khorasan Razavi Province. All collected sera were screened using the direct agglutination test (DAT). The sera with anti-Leishmania infantum antibodies at a titre of 1:100 were considered positive for VL infection and serum titration was performed from 1:100 to 1:102,400. Nine (18.4%) patients were sero-positive according to DAT. The distribution of sera titrations were as follows: 1:100 (n = 6) 1:1600 (n = 1); 1:25,600 (n = 1) and 1:102,400 (n = 1). All sero-positive cases showed clinical signs and symptoms. The most predominant signs and symptoms of co-infection of visceral leishmaniasis in HIV-positive patients were pneumonia (n = 2), hepatosplenomegaly (n = 2), lymphadenopathy (n = 2), anaemia (n = 1), prolonged fever (n = 1) and cachexia (n = 1). Our finding shows that VL (or kala-azar) is an opportunistic disease in HIV-positive patients that may be occurred in VL endemic areas of Iran. PMID:24100200

    Human immunodeficiency virus (HIV)-infected patients have an increased risk of developing osteopenia or osteoporosis compared with healthy individuals. Our aim was to compare dual X-ray absorptiometry (DXA), the gold standard for measuring bone mineral density (BMD), with bone quantitative ultrasound (QUS), an alternative technique for predicting fractures and screening low BMD, at least in postmenopausal populations. We analyzed DXA and QUS parameters to investigate their accuracy in the diagnosis and prediction of bone alterations in a cohort of 224 HIV-1-positive patients. The speed of sound (SOS), broadband ultrasound attenuation (BUA) and stiffness index (SI) parameters showed a moderate correlation with DXA, especially with total-body BMD (r coefficient of 0.38, 0.4 and 0.42 respectively), particularly in the female subgroup. In addition, multivariate analysis of HIV-positive patients assessed for vertebral fractures indicated that QUS was more effective than DXA at predicting the risk of fracture. QUS can be used as an additional tool for analyzing bone density in HIV-positive patients and its case of use and low cost make it especially suitable for resource-limited settings where DXA is not employed.

    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. PMID:27293276

    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.

    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.

    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.

    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. PMID:24713227

    We ran a comparative analysis of all patients for whom a positive culture of Mycobacterium tuberculosis complex was available between April 2004 and October 2005 and whose HIV serology results were known, with spoligotyping results (n = 163) split into 49 HIV-positive patients and 114 HIV-negative patients. Spoligotype international type 373 (SIT373) (T1 lineage), which was highly prevalent among the HIV(+) patients, was totally absent from the HIV(-) population, suggesting that we had a specific clone affecting nearly 1/3 of all HIV-tuberculosis (TB)-coinfected patients. Among the LAM10-CAM sublineage strains, we had only a single strain of SIT403 among HIV(-) patients (0.88%), as opposed to 12.25% of the HIV(+) population (χ(2) = 10.77; P < 0.01), indicating a strong association between the strain and the HIV(+) population. The LAM10-CAM lineage spoligotype SIT61 was prevalent among the 2 subsets (37.72% in HIV(-) versus 12.24% in HIV(+) populations), though, with a significant difference between the 2 groups (χ(2) = 10.53; P < 0.01). However, there was no significant difference for SIT53 (T1 lineage) in the 2 subsets: 6.14 versus 8.2% (χ(2) = 0.22; P > 0.05). A total of 7/49, or 14.3%, other SITs among HIV(+) patients were not found among the HIV(-) patients. When added to the most prevalent SIT among HIV(+) patients (SIT373; n = 16), 23/49, or 47%, isolates among HIV-TB-coinfected patients were unique. We conclude that further studies should be carried out to investigate the evolution of these genotypes and others in the emergence of multidrug resistance and control of tuberculosis in Nigeria.

    Background HIV, HBVand HCV is major public health concerns. Because of shared routes of transmission, HIV-HCV coinfection and HIV-HBV coinfection are common. HIV-positive individuals are at risk of coinfection with HBV and HCV infections. The prevalence rates of coinfection with HBV and HCV in HIV-patients have been variable worldwide depending on the geographic regions, and the type of exposure. Aim This study aimed to examine HBV and HCV coinfection serologically and determine the shared and significant factors in the coinfection of HIV-positive patients. Methods This descriptive, cross-sectional study was carried out on 391 HIV-positive patients including 358 males and 33 females in Lorestan province, west Iran, to survey coinfection with HBsAg and anti-HCV. The retrospective demographic data of the subjects was collected and the patients' serums were analyzed by ELISA kits including HBsAg and anti-HCV. The collected data was analyzed with SPSS software (15) and Chi-square. Fisher's exact test with 5% error intervals was used to measure the correlation of variables and infection rates. Results The results of the study indicated that the prevalence of coinfection in HIV-positive patients with hepatitis viruses was 94.4% (370 in 391), out of whom 57 (14.5%) cases were HBsAg positive, 282 (72%) cases were anti-HCV positive, and 31 (7.9%) cases were both HBsAg and anti-HCV positive. Conclusion There was a significant correlation between coinfection with HCV and HBV and/or both among HIV-positive patients depending on different variables including sex, age, occupation, marital status, exposure to risk factors.(p < 0.001).

    Background: Micronutrients such as B12 and folic acid deficiencies are found in higher number in HIV-infected patients. Objective: We conducted a study to examine the effect of Vitamin B12 and folic acid supplementation on neuropsychiatric manifestations, CD4 count, and anthropometric measurements in HIV-positive patients. Materials and Methods: Three different groups of HIV patients, namely, HIV patients with tuberculosis, HIV patients with neuropsychiatric manifestations, and asymptomatic HIV patients with 50 patients in each group were included in the study. Baseline and follow-up CD4 count, anthropometric measurements, neuropsychiatric assessments, Vitamin B12, and folic acid estimation were done. Results: The prevalence of folic acid deficiency was 27.1% in Group I, 31.9% in Group II, and 23.4% in Group III. The prevalence of Vitamin B12 deficiency was 8.16% in Group I, 6.12% in Group II, and 4.16% in Group III. HIV patients with neuropsychiatric manifestations were noted to have the lowest mean mini–mental score. After the supplementation of vitamins, anthropometric measurements, MMSE as well as Hamilton depression scores, improved in all the three groups whereas Hamilton anxiety scores improved only in Group III. The CD4 count also improved in Groups I and II after the supplementation of vitamins. Conclusion: Folic acid deficiency was highest among neuropsychiatric patients. The majority of people who had a folic acid deficiency have shown improvement in their neuropsychiatric assessment scores as well as CD4 count after its supplementation. PMID:27365952

    Many human immunodeficiency virus (HIV) infected persons are coinfected with hepatitis C virus (HCV) and with the use of highly active antiretroviral therapy, liver disease from HCV has become an important cause of morbidity and mortality. The current guidelines recommend that human immunodeficiency virus and HCV coinfected patients be evaluated and treated for HCV if there are no major contraindications to treatment. Coinfected patients treated with pegylated interferon-a and ribavirin have sustained virologic responses (SVRs) of 27% to 40% which for a variety of reasons are lower than those reported in HCV mono-infected patients. Understanding that most patients will not achieve SVRs, strategies to evaluate for the role of maintenance interferon in delaying complications of liver disease are being evaluated. In patients who have failed prior treatment, cannot tolerate treatment, or who have contraindications to HCV treatment, the use of highly active antiretroviral therapy with careful monitoring for hepatotoxicity and aggressive counseling on alcohol and substance abuse may slow down fibrosis progression. As the data on liver transplantation in coinfected patients accumulate, patients with end stage liver disease should be referred early for evaluation in a transplant center. As new drugs for HCV are being developed, it will be of utmost importance to include coinfected patients earlier in the process on new drug trials and therapeutic strategies. PMID:17198069

    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

    Mycobacterial opportunistic infections are a major cause of morbidity and mortality among patients living with HIV (PLHIV) worldwide. Nontuberculous mycobacterial (NTM) infection is one of the leading causes of opportunistic infection in patients with advanced acquired immunodeficiency syndrome i.e., with CD4 count less than 50/cu.mm. Mycobacterium avium complex (MAC) is among the most common opportunistic bacterial infections in those patients with advanced immunodeficiency apart from cryptococcal meningitis, progressive multifocal leukoencephalopathy, etc. Common presentations of mycobacterium avium complex are fever, lymphadenitis and respiratory disease. Immune reconstitution disease is also known to manifest with MAC infections in PLHIV on highly active antiretroviral therapy. Very few cases of central nervous system involvement due to NTM infection have been described. We are reporting a case of advanced acquired immunodeficiency who presented with brain abscess due to Mycobacterium avium intracellulare. PMID:22412276

    Risk of bone fractures in patients with HIV infection is greater than in the general population, particularly in those co-infected with hepatitis viruses. We compared bone mineral density (BMD) and muscular strength, measured by hand grip test (HG), in HIV mono-infected and co-infected patients. T-score values were lower in HIV patients co-infected with hepatitis viruses vs. mono-infected individuals. Since no significant correlations between HG and T-scores were found, we hypothesize that these factors belong, at least in part, to independent pathways, so both should be taken into account as risks for fragility fractures. Larger prospective studies are needed to confirm this hypothesis. PMID:26922987

    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. PMID:26475880

    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. PMID:24841196

    The diagnosis of patients with pulmonary infiltrates and human immunodeficiency virus (HIV) infection remains a challenge. In current clinical practice the gold standard for Pneumocystis jirovecii pneumonia (PCP) diagnosis remains the identification of the organism in broncoalveolar lavage (BAL) using microscopy (e.g., silver stain). (1->3)-β -D-glucan (BG) is a polysaccharide that is present within the cell wall of Pneumocystis and other fungi. We analyzed serum and BAL lavage fluid from a cohort of 119 patients that did have HIV, a diagnosis of pneumonia and underwent bronchoscopy (FOB) for diagnosis of PCP. The discriminative power of serum BG for the diagnosis of PCP in this group of patients was very high. Using a cutoff of 300 pg/mL, the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were 91%, 92%, 89% and 93% respectively. A model for ROC with just serum BG (N = 108) had an AUC of 0.95. Serum procalcitonin (PCT) and BAL BG were not as accurate for the diagnosis of PCP. For BAL BG using a cutoff of 783 pg/mL, the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were 72%, 79%, 72% and 79% respectively. The differences between the medians for serum PCT between the group with a without PCP did not reach statistical significance (p=0.6137). The measurement of serum BG should be incorporated in the diagnostic work up of HIV positive patients with dyspnea and infiltrates on chest X ray. Our study confirms the diagnostic value of serum BG previously reported by others but we add a cutoff value that we believe is more accurate for patients with AIDS and suspicion of PCP.

    Effective antiretroviral therapy (ART) requires excellent adherence. Little is known about how to improve ART adherence in many HIV/AIDS-affected countries, including China. We therefore assessed an adherence intervention among HIV-positive patients in southwestern China. Eighty subjects were enrolled and monitored for 6 months. Sixty-eight remaining subjects were randomized to intervention/control arms. In months 7–12, intervention subjects were counseled using EDM feedback; controls continued with standard of care. Among randomized subjects, mean adherence and CD4 count were 86.8 vs. 83.8% and 297 vs. 357 cells/μl in intervention vs. control subjects, respectively. At month 12, among 64 subjects who completed the trial, mean adherence had risen significantly among intervention subjects to 96.5% but remained unchanged in controls. Mean CD4 count rose by 90 cells/μl and declined by 9 cells/μl among intervention and control subjects, respectively. EDM feedback as a counseling tool appears promising for management of HIV and other chronic diseases. PMID:19771504

    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. PMID:23917370

    Visceral leishmaniasis is a disease caused by a haemoflagellate protozoan of the genus Leishmania. It has a wide geographical spread. Classic cases are found primarily in children and present with typical features that include fever, anaemia, hepatosplenomegaly, hypergammaglobulinaemia, and pancytopenia. The diagnosis is usually achieved by bone marrow smears, culture and serology; however, it can manifest itself atypically, mostly in patients infected with HIV and geriatric immunocompetent patients. We report an unusual case of visceral leishmaniasis diagnosed in a 27 year-old HIV-infected male who presented with abdominal discomfort and diarrhoea of four weeks duration associated with nausea and vomiting, but with no typical symptoms or signs of visceral leishmaniasis. The diagnosis was established through the identification of the Leishmania organism in duodenal and colonic biopsies and confirmed by subsequent bone marrow smears. PMID:21969901

    Background: Despite the success of developed countries in preventing the spread of HIV/AIDS, the disease is expanding in developing countries where an unfavorable attitude exists among people, health professionals and employees. This study aimed to assess the stigmatized attitude among health care providers toward people living with HIV (PLWHA). Methods: The study is a cross-sectional survey. The data were gathered using a structured questionnaire. The study sample included 575 health care providers of public and private hospitals in Shiraz. The data were gathered using a structured questionnaire in spring 2014. Data analysis was carried out using the Statistical Package for Social Sciences, version 21. Results: The most dominant attitude of the health care providers toward HIV/AIDS patients was related to fear (42.42%). According to the results of this study, there was a significant relationship between stigmatized attitude of the health care providers and their religious beliefs, society stigmatized attitude, and knowledge of transmission routes. The relationship between social stigmatized attitude of health care providers and their knowledge of transmission routes, with their willingness to provide services to patients is significant, as well (P<0.05). 39.6% and 46.2% of the respondents preferred not to provide services to the prostitutes and homosexual patients. Conclusion: Fear of contamination and social stigmatized attitude are the main impediments to dealing with patients and providing services to them. Hence, it seems that creating an effective knowledge about transmission and correcting the socio-cultural beliefs of health providers are two key strategies to tackle this problem. PMID:26448956

    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

    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

    Background 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. Methods 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. Results 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<. 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. Conclusions Methadone maintenance was well accepted by HIV+ and HIV− opioid dependent individuals and has the potential for significant

    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

    There is a high burden of underlying substance use and mental illness in HIV-infected populations. HIV-care settings provide an important opportunity to assess substance and mental health needs among HIV-positive patients and to provide or make referrals for appropriate treatment services. In 2003, with funding from the Center for Substance Abuse Treatment (CSAT), we developed a model of integrated substance-use counselling and referral for treatment within a primary care HIV-care setting at The Miriam Hospital in Providence, Rhode Island. The project uses a multidisciplinary approach to provide linkage to treatment services for substance use and mental illness as well as to help participants with social service needs, such as housing and medical coverage, to ensure continuity of care and optimal HIV treatment adherence. Twelve percent of the 965 HIV-infected patients in care at our center have been enrolled in the project. Of these, all have a current substance-use disorder and 79.3% have been diagnosed with a mental illness. In addition, most participants are hepatitis C-positive (HCV) (65.5%). The majority of participants are on antiretroviral therapy (76.7%). Participants have been referred for the following treatment modalities: intensive outpatient services, methadone, buprenorphine, outpatient services and residential as well as individual and group counselling. Our model has been successful in assessing the substance-use and mental health needs of HIV-infected individuals with numerous co-morbidities and referring them for ancillary medical and social services.

    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. PMID:23997948

    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.

    Summary Knowledge of HIV transmission is a prerequisite to practicing safer behaviors to prevent HIV infections and may be expected to vary by region because of cultural and socioeconomic determinants. A cross-sectional study was conducted in rural Kenya using a standardized questionnaire assessing HIV transmission knowledge, socio-demographic and other characteristics. Participants were recruited from the voluntary counseling and testing clinic and the general hospital population of Moi District Hospital. “High” HIV transmission knowledge scorers (≥ 81%) (Mean score) were compared with “low” scorers (<81%). Bivariate and multivariate logistic regression analyses were performed to examine factors associated with HIV transmission knowledge. Of 214 participants, 70 (33%) were HIV-positive, 104 (49%) were HIV-negative, and 40 (19%) did not know. Factors associated with low knowledge in multivariate analyses were lower education (OR 2.36, CI 1.03–5.46), lower household money on healthcare (OR 2.03, CI 1.28–3.21), higher clinic transportation costs (OR 3.14, CI 1.20–9.82), sex without a condom (OR 2.18, CI 1.12–4.26), positive HIV status vs. negative (OR 2.50, CI 1.22–5.26) and positive HIV status vs. unknown (OR 3.57, CI 1.33–9.09). Mean HIV transmission knowledge score was relatively high; however, a large proportion of patients demonstrated low knowledge. Identifying individuals at risk for low knowledge will support targeted HIV education and prevention programs. PMID:23495369

    The study explored the perceptions, knowledge and attitudes of patients, health workers and traditional healers about the use of traditional medicine and Anti Retroviral Therapy (ART). The study explored the perceptions, knowledge and attitudes of patients, health workers and traditional healers about the use of traditional medicine and Anti Retroviral Therapy (ART), using an exploratory qualitative design in two provinces of South Africa: an urban township health facility in the Western Cape, and a rural district hospital in KwaZulu-Natal (KZN) with antennal HIV rate of 32% and 28%'respectively. In-depth interviews were conducted with 14 participants: six HIV patients on ART and using Traditional Medicine(TM), two doctors, two nurses and four traditional healers. Two focus group discussions -one at each site - were held with community health workers who work with HIV-positive patients (Western Cape [5] and in KZN [4]). Patient said to have used Traditional Healing Practices (THP) before they were diagnosed with HIV, and some who have been diagnosed with HIV continue using TM in conjunction with ART and/or Cotrimoxazole prophylaxis. Patients preferred not to disclose THP to health professionals because of lack of support and understanding. Patients utilize THP because of family expectations, privacy and confidentiality, especially when they have not disclosed their HIV status. Healthcare professionals had strong negative opinions about THP, especially for HIV-positive patients. Traditional healers supported the patient's rationale for THP use. This study revealed a need to better understand factors involved in patients' choosing to use THP concurrently with ART. PMID:23983385

    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. PMID:25435196

    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

    Background: Cell-mediated immunity (CMI) by CD4 + Th (T helper)-type cells is the predominant host defense mechanism against Oral Candidiasis (OC) in HIV-infected individuals. Weakened CMI and depletion of CD4 + T cells are the main factor contributing to the output of OC in HIV-positive individuals. The cytokines produced by Th1, Th2 and Th17 cells play a role in mediating an increased susceptibility to OC during HIV infection. Objectives: The present study investigated plasma concentration of IFN-γ, IL-4, IL-6 and IL-17 in HIV-1 patients suffering from OC. Patients and Methods: In total, 98 samples in four groups (HIV-positive and HIV-negative persons with and without OC) were obtained from the oral cavities and cultured on Sabouraud’s dextrose agar and CHROMagar. Also blood samples were obtained to assess plasma level of IFN-γ, IL-4, IL-6 and IL-17 using ELISA technique. Results: There was a statistically significant difference in the plasma concentration of IFN-γ, IL-6 and IL-17 but not about IL-4. Our findings suggest a significant interaction between fungal infection and HIV on expression of assessed cytokines. Conclusions: Fungal infection and HIV alone and together could seriously alter immune system function as assessed by measuring the levels of the plasma cytokines. Therefore, these results provide important new information relative to the putative immune-based factors associated with resistance and/or susceptibility to OC in HIV-positive persons. PMID:27127595

    Pneumocystis jirovecii pneumonia (PCP) is an acute and life-threatening lung disease caused by the fungus Pneumocystis jirovecii The presentation of PCP in HIV-positive patients is well-known and consists of a triad of dyspnea, fever, and cough, whereas the presentation of PCP in HIV-negative patients is atypical and consists of a sudden outbreak, O2 desaturation, and a rapid lethal outcome without therapy. Despite the availability of direct and indirect identification methods, the diagnosis of PCP remains difficult. The cycle threshold (CT) values obtained by quantitative PCR (qPCR) allow estimation of the fungal burden. The more elevated that the fungal burden is, the higher the probability that the diagnosis is pneumonia. The purposes of the present study were to evaluate the CT values to differentiate colonization and pneumonia in a population of immunocompromised patients overall and patients stratified on the basis of their HIV infection status. Testing of bronchoalveolar lavage (BAL) fluid samples from the whole population of qPCR-positive patients showed a mean CT value for patients with PCP of 28 (95% confidence interval [CI], 26 to 30) and a mean CT value for colonized patients of 35 (95% CI, 34 to 36) (P < 10(-3)). For the subgroup of HIV-positive patients, we demonstrated that a CT value below 27 excluded colonization and a CT value above 30 excluded PCP with a specificity of 100% and a sensitivity of 80%, respectively. In the subgroup of HIV-negative patients, we demonstrated that a CT value below 31 excluded colonization and a CT value above 35 excluded PCP with a specificity of 80% and a sensitivity of 80%, respectively. Thus, qPCR of BAL fluid samples is an important tool for the differentiation of colonization and pneumonia in P. jirovecii-infected immunocompromised patients and patients stratified on the basis of HIV infection status with different CT values.

    Non-tuberculous mycobacteria are rare but important causes of infection in HIV-positive individuals. A 28-year-old HIV-positive male presented with a high fever, non-productive cough, right subcostal pain, splenomegaly, a very low CD4 count, elevated C-reactive protein and erythrocyte sedimentation rate, and a normal white blood cell count. The suspicion of tuberculosis (TB) was very high, and sputum samples were positive for acid-fast bacilli. Standard quadruple anti-TB therapy was initiated, but once culture of the sample revealed Mycobacterium kansasii, pyrazinamide was withdrawn. Highly active antiretroviral therapy (HAART) was initiated soon after, consisting of abacavir/lamivudine and efavirenz. The patient's general condition deteriorated 2 weeks after HAART initiation, which could have been due to the development of immune reconstitution inflammatory syndrome (IRIS). The patient recovered and was discharged in good condition. However, the results of resistance testing of the isolated organism arrived after discharge, and showed isoniazid and streptomycin resistance. This is the first case report of M. kansasii infection from Serbia and shows the difficulties encountered during the course of treatment. PMID:26603644

    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

    Subcutaneous injections of fermented and unfermented aqueous extracts of Viscum album L. result in a local inflammatory reaction at the injection site. In this trial, the symptoms associated with this local reaction were investigated. Furthermore the occurrence of local reactions was tried to correlate with an increase in CD3/25- and CD8/38-positive lymphocyte counts, with eosinophilic granulocyte numbers, and with the formation of mistletoe lectin antibodies. Included in the trial were 30 HIV-antibody-positive patients and 17 healthy non-smokers, aged 24-51 years. The CD4 cell count in the HIV-negative subjects was > 800/microliter, compared with 200-600/microliter in the HIV-positive patients. All study participants had a Karnofsky score > or = 70. The trial subjects were observed over a period of 18 weeks. With escalation of the dose of a fermented and unfermented extract of Viscum album L. (Iscador Qu Spezial and Viscum album QuFrF), there was an increase in local reactions. Erythema at the injection site was the most frequently reported symptom. Between the doses and the symptoms induration, swelling and pruritus were marked correlations. Effects of the application of mistletoe extracts on the immune system were demonstrated by an increase in CD3/25-positive lymphocyte counts and antibodies against mistletoe-lectins. There were no changes in eosinophilic granulocytes or CD8/38-positive lymphocyte populations. For evaluation of the therapeutic applications of mistletoe extracts in HIV-positive patients it is advisable to assess primarily activation of CD3-positive lymphocytes and the patient response on the basis of the local reaction. The local inflammatory reaction at the injection site is desirable and well tolerated if the reaction is smaller than 5 cm in diameter. PMID:10337457

    Objective The HIV epidemic has increased the proportion of patients with smear-negative and extrapulmonary tuberculosis (TB) diagnoses, with related higher rates of poor TB treatment outcomes. Unlike in smear-positive pulmonary TB, no interim markers of TB treatment progress are systematically used to identify individuals most at risk of mortality. The objective of this study was to assess the association of body mass index (BMI) change at 1 month (±15 days) from TB treatment start with mortality among HIV-positive individuals with smear-negative and extrapulmonary TB. Methods and Findings A retrospective cohort study of adult HIV-positive new TB patients in Médecins Sans Frontières (MSF) treatment programmes in Myanmar and Zimbabwe was conducted using Cox proportional hazards regression to estimate the association between BMI category change and mortality. A cohort of 1090 TB patients (605 smear-negative and 485 extrapulmonary) was followed during TB treatment with mortality rate of 28.9 per 100 person-years. In multivariable analyses, remaining severely underweight or moving to a lower BMI category increased mortality (adjusted hazard ratio 4.05, 95% confidence interval 2.77–5.91, p<0.001) compared with remaining in the same or moving to a higher BMI category. Conclusions We found a strong association between BMI category change during the first month of TB treatment and mortality. BMI category change could be used to identify individuals most at risk of mortality during TB treatment among smear-negative and extrapulmonary patients. PMID:22545150

    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

    Summary ALS gene expression was studied in the hyposalivatory rat model of oral candidiasis and in clinical specimens collected from HIV-positive patients to assess similarities in expression patterns between the model system and clinical isolates. Two C. albicans strains, SC5314 and OY-2-76, were used in the rat model system and infection progressed for 3 or 5 days. The strains produced similar oral lesions at 3 days. At 5 days, strain OY-2-76 produced more superficial lesions containing relatively more yeast forms compared to invasive hyphal forms observed for strain SC5314. For all infections, the most severe lesions were observed on the tongue and gingiva overlying the mandible. ALS transcripts were easier to detect by RT-PCR later in infection and under other conditions where more fungal cells were present. Expression of ALS1, ALS2, ALS3 and ALS4 was observed in rats infected for 3 days with ALS5 and ALS9 transcripts detected after 5 days of infection. Expression of ALS6 was observed in a single specimen from a 5-day infection while ALS7 transcript was never found. Expression of all ALS genes was observed in oral clinical material collected from HIV-positive patients although ALS6 and ALS7 transcripts required an extra PCR amplification step to be detected. Overall, the patterns of ALS gene expression were similar between the rat model and human clinical specimens, suggesting that the model would be useful for studying the phenotype of als/als mutant strains.

    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.

    Objective Estimates of CD4 response to antiretroviral therapy (ART) obtained by averaging data from patients in care, overestimate population CD4 response and treatment program effectiveness because they do not consider data from patients who are deceased or not in care. We use mathematical methods to assess and adjust for this bias based on patient characteristics. Design We examined data from 25,261 HIV-positive patients from the East Africa IeDEA Consortium. Methods We used inverse probability of censoring weighting (IPCW) to represent patients not in care by patients in care with similar characteristics. We address two questions: What would the median CD4 be “had everyone starting ART remained on observation?” and “were everyone starting ART maintained on treatment?” Results Routine CD4 count estimates were higher than adjusted estimates even under the best-case scenario of maintaining all patients on treatment. Two years after starting ART, differences between estimates diverged from 30 cells/µL, assuming similar mortality and treatment access among dropouts as patients in care, to over 100 cells/µL assuming 20% lower survival and 50% lower treatment access among dropouts. When considering only patients in care, the proportion of patients with CD4 above 350 cells/µL was 50% adjusted to below 30% when accounting for patients not in care. One-year mortality diverged 6–14% from the naïve estimates depending on assumptions about access to care among lost patients. Conclusions Ignoring mortality and loss to care results in over-estimation of ART response for patients starting treatment and exaggerates the efficacy of treatment programs administering it.

    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

    Anal intraepithelial neoplasia (AIN) is associated with HPV infection and can be detected by cytological screening. While conventional exfoliative cytology (CC) is a low-cost and nonaggressive method, liquid-based cytology (LBC) tends to give clearer readings. Although studies of the efficacy of anal cancer screening methods would be of great importance for groups at high risk for AIN, few such studies have been conducted. The aim of the present study was to assess the concordance of CC and LBC in diagnosing anal pre-neoplastic lesions, and to compare cytological results with anoscopy, histopathological, and molecular biology findings. Comparative study involving 33 HIV-positive patients, who underwent anoscopy and biopsy of suspected lesions. Concordance between the two cytology methods was calculated, as were the associations between cytology results and findings from other screening methods. A total of 54.5% of cases were considered AIN-negative by CC and LBC, and concordance between the two methods was statistically significant (P < 0.05). Anoscopy was negative in 15 of the 18 CC- and LBC-negative cases. CC identified 75% of patients with positive biopsy, while LBC identified 85.71% of these patients. Molecular biology results showed that patients with LSIL tested positive for the highest number of HPV subtypes. The associations between positive biopsy and high grade HPV, HPV 16, and multiple HPV infections were not statistically significant. Conventional and liquid-based cytology are equally effective in screening for anal preneoplastic lesions. PMID:24591207

    Background 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). Methods 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). Results 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). Conclusion The findings of this study

    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

    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.

    We have re-examined the evidence on which current British Thoracic Society recommendations for primary and secondary prophylaxis and therapy of tuberculosis are based. We suggest that in a country such as the UK with a low prevalence of tuberculosis, primary prophylaxis should be offered primarily to tuberculin positive or anergic patients from high-incidence groups, including immigrants from high-prevalence countries, intravenous drug users and those with previous tuberculosis, that secondary prophylaxis be withheld from all but very high-risk patients and that four drug regimens which include ethambutol should be used for patients originating from, or who have lived in areas of the world with more than 2% primary isoniazid resistance.

    The sensitivity of microscopy for the diagnosis of tuberculosis (TB) is around 50% but decreases by about 15% in patients with suspected TB who are coinfected with HIV. Here, we compared the accuracies of three microscopy methods for processing sputum smears (concentration by centrifugation with or without N-acetyl-l-cysteine [NALC] and concentration by filtration on a polycarbonate membrane) to that of culture on Ogawa-Kudoh medium as the gold standard method. Sputum samples were obtained from 432 patients with suspected pulmonary TB, of whom 60% were infected with HIV. Analysis was performed using the first specimen. Compared to the gold standard culture, the small-membrane-filter (SMF) method was the most sensitive microscopic method. In HIV-infected TB patients, the sensitivity of the SMF method was significantly higher than those for centrifugation of sputum samples with or without NALC treatment (61.9%, 47.6%, and 45.2%, respectively; P = 0.001). Similarly, in TB patients without HIV infection, the sensitivity of the SMF method was significantly higher than those for centrifugation of sputum samples with or without NALC treatment (81.8%, 63.6%, and 57.5%, respectively; P = 0.001). In the two study groups, TB patients with or without HIV, no significant differences between the specificities of the three methods were observed. Handling of the second sputum sample similarly by centrifugation with or without NALC and by the SMF method increased positivities by 13%, 11%, and 4%, respectively. The overall agreement between microscopy and culture was above 90% for all groups. Microscopic evaluation of the sputum samples treated with NALC compared to those not treated with NALC did not show any increase in sensitivity. Altogether, the sensitivity of the SMF method is higher than those of the other two microscopic methods studied without a loss of specificity. PMID:23804389

    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.

    2013-01-01

    Background Challenges to HIV care in resource limited settings (RLS) include malnutrition. Limited evidence supports the benefit of nutritional supplementation when starting antiretroviral therapy (ART) in RLS. Methods Randomized controlled pilot study. HIV-positive ART-naive adults with self-reported weight loss were randomized to receive ART plus FutureLife porridge® nutritional supplement (NS) (388 kcal/day) or ART alone (Controls) for 6 months. Patients returned for monthly assessments and blood was drawn at enrolment and 6 months on ART. Differences in body composition, biochemical and laboratory parameters were estimated at 6 months on treatment. Results Of the 36 randomized patients, 26 completed the 6 month follow-up (11 NS vs 15 Controls). At enrolment, groups were similar in terms of age, gender, body mass index (BMI) and bioelectrical impedance. NS patients had a lower median CD4 count (60 cells/mm3 [IQR 12–105 vs 107 cells/mm3 [IQR 63–165]; p = 0.149) and hemoglobin (10.3 g/dL [IQR 9.0-11.3] vs 13.1 g/dL [IQR 11.1-14.7]; p = 0.001). At 6 months, NS patients increased their median CD4 count by 151 cells/mm3 [IQR 120–174) vs 77 cells/mm3 [IQR 33–145] in the Controls. NS patients had higher mean percentage change in body weight (12.7% vs 4.9%; p = 0.047), BMI (7.8% vs 5.5%; p = 0.007), absolute CD4 count (83.0% vs 46.4%, p = 0.002) and hemoglobin (9.5% vs 1.0%; p = 0.026). Patients in the NS arm had a higher mean percentage fat-free mass (16.7% vs −3.5%, p = 0.036), total body water (13.0% vs −1.9%, p = 0.026), intracellular water (16.1% vs −4.1%, p = 0.010) and basal metabolic rate (5.3% vs −0.2%, p = 0.014) compared to Controls. Patients in the NS arm also showed an improvement in physical activity at 6 months post-ART initiation compared to Controls (p = 0.037). Conclusion Preliminary results are encouraging and suggest that NS taken concurrently with ART can promote weight gain

    Under-reporting of ADR may be associated with poor knowledge, attitudes and practices to pharmacovigilance. This study evaluated knowledge, attitudes and practices of healthcare professionals about ADR monitoring and reporting following interventions. This longitudinal study included 36 healthcare professionals participating in ART program in a tertiary hospital. Interventions included group training on pharmacovigilance (PV) and provision of ADR reporting forms amongst others. Assessments were conducted at months 0 and 6 post-interventions using study-specific Likert-type instruments. Mean attitude scores above midpoint of 3.6 on 5-point scale were regarded as positive and below as negative. P<0.05 used to determine statistical significance. Mean age of participants was 36.6 (95%CI, 34.5–38.7) years; 61.1% males; 44.4% doctors, 13.9% pharmacists, 19.4% nurses, 8.3% laboratory scientists, 8.3% record officers and 5.6% welfare officers. None had received training on PV previously. Mean knowledge test score increased from 53.6% (95%CI, 44.6–63.6) at pre-intervention to 77.1% (95%CI, 72.8–81.4) at post-intervention with a mean change of 146.9% (95%CI, 60.5–233.3; p=0.000). Mean rated attitude scores increased from 3.6 (95%CI, 3.4–3.8) at pre-intervention to 4.2 (95%CI, 4.0–4.4) at post-intervention; the difference was statistically significant (p=0.000). 75.8% reported that ADR reporting forms were not readily available at pre-intervention compared to 18.2% at postintervention; 15.2% had reported ADR previously at pre-intervention compared to 69.7% at post-intervention; 12.1% reported providing information regarding ADRs and its management always at pre-intervention compared to 45.5% at post-intervention; these differences were statistically significant (p<0.05). Lack/inadequate knowledge, unavailability of reporting forms and negative attitudes were barriers identified; and addressing them resulted in significant improvement in this setting. Scaling up

    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. © 2015 The Authors.

    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

    Background Diagnosis of pulmonary tuberculosis (TB) among human immunodeficiency virus (HIV) patients remains complex and demands easy to perform and accurate tests. Xpert®MTB/RIF (MTB/RIF) is a molecular TB diagnostic test which is rapid and convenient; the test requires minimal human resources and reports results within two hours. The majority of performance studies of MTB/RIF have been performed in high HIV burden settings, thus TB diagnostic studies among HIV patients in low HIV prevalence settings such as Peru are still needed. Methodology/Principal Findings From April 2010 to May 2011, HIV-positive patients with high clinical suspicion of TB were enrolled from two tertiary hospitals in Lima, Peru. Detection of TB by MTB/RIF was compared to a composite reference standard Löwenstein-Jensen (LJ) and liquid culture. Detection of rifampicin resistance was compared to the LJ proportion method. We included 131 patients, the median CD4 cell count was 154.5 cells/mm3 and 45 (34.4%) had TB. For TB detection among HIV patients, sensitivity of MTB/RIF was 97.8% (95% CI 88.4–99.6) (44/45); specificity was 97.7% (95% CI 91.9–99.4) (84/86); the positive predictive value was 95.7% (95% CI 85.5–98.8) (44/46); and the negative predictive value, 98.8% (95% CI 93.6–99.8) (84/85). MTB/RIF detected 13/14 smear-negative TB cases, outperforming smear microscopy [97.8% (44/45) vs. 68.9% (31/45); p = 0.0002]. For rifampicin resistance detection, sensitivity of MTB/RIF was 100% (95% CI 61.0–100.0) (6/6); specificity was 91.0% (95% CI 76.4–96.9) (30/33); the positive predictive value was 66.7% (95% CI 35.4–87.9) (6/9); and the negative predictive value was 100% (95% CI 88.7 –100.0) (30/30). Conclusions/Significance In HIV patients in our population with a high clinical suspicion of TB, MTB/RIF performed well for TB diagnosis and outperformed smear microscopy. PMID:22970271

    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

    Febrile illnesses occur frequently among HIV positive patients and these are often treated presumptively as malaria in endemic areas. Parasite-based diagnosis of malaria will eliminate unnecessary treatment, reduce drug–drug interactions and the chances for the emergence of drug resistant Plasmodium. We evaluated finger prick blood samples from 387 people living with HIV (PLWHIV) and suspected of having malaria by expert microscopy and Paracheck-PfTM – a histidine-rich protein-II based malaria rapid diagnostic test. The study was conducted at the PEPFAR supported AIDS Prevention Initiative in Nigeria (APIN) Clinic of the University College Hospital Ibadan, southwest Nigeria. Outcome parameters were prevalence of malaria parasitemia, sensitivity and specificity of Paracheck-Pf as well as the positive and negative predictive values for Paracheck-Pf using microscopy of Giemsa-stained blood film as gold standard. Malaria parasites were detected in 19.1% (74/387) of enrollees by microscopy and 19.3% (74/383) by Paracheck-Pf. Geometric mean parasite density was 501/μl (range 39–749 202/μl). Sensitivity and specificity of Paracheck-Pf at all parasite densities were 55.4% and 89.3% while corresponding figures at parasite densities ≧200/μl were 90.9% and 90.3%. Sensitivity and specificity at parasite densities ≧500/μl was 97.6% and 90.3%. Positive and negative predictive values for parasite density ≧200/μl were 55.4% and 98.7%, respectively. Paracheck-pf was found to be a useful malaria diagnostic tool at parasite densities ≧200/μl facilitating appropriate clinical management. PMID:23683333

    Background HIV adherence to erythrocytes has been demonstrated in vitro, and it has been suggested that erythrocytes may be carriers of the virus. However, the association between HIV particles or viral proteins and erythrocytes in HIV-infected individuals is still to be elucidated. Methodology/Principal Findings HIV-positive participants (n = 112) were classified into two groups according to values of three plasma viral loads (pVL) determined during the 12-month period prior to the study. The first group included 71 individuals with detectable pVL, whereas the second group included 41 individuals with undetectable pVL. Plasma viral load, erythrocyte-associated p24-antigen and p24-antigen in plasma were determined at the moment of the study. A total of 51 out of the 71 patients with detectable pVL showed erythrocyte-associated p24-antigen whereas 13 showed p24-antigen in plasma. Twenty-two out of the 51 patients with erythrocyte-associated p24-antigen showed pVL<10,000 copies/ml and undetectable p24-antigen in plasma. The data indicates that the amount of erythrocyte-associated p24-antigen was not related to p24-antigen in plasma or pVL levels in this group. Among the 41 patients with prior undetectable pVL, eight presented detectable pVL and erythrocyte-associated p24-antigen at the moment of the study. The other 33 showed undetectable pVL and five of these presented erythrocyte-associated p24-antigen. A positive relationship was found between the presence of erythrocyte-associated p24-antigen and the detectable pVL at the moment of the study (p<0.00001). Even more, in another series of assays, a detectable viral load associated to erythrocytes was determined and it was always accompanied by erythrocyte-associated p24-antigen detection. Conclusions/Significance This study demonstrates the presence of erythrocyte-associated p24-antigen in HIV-infected individuals. Since erythrocyte-associated p24-antigen is not always related to pVL or p24-antigen in plasma

    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.

    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

    Introduction HIV-positive patients receiving combination antiretroviral therapy (cART) frequently experience metabolic complications such as dyslipidemia and insulin resistance, as well as lipodystrophy, increasing the risk of cardiovascular disease (CVD) and diabetes mellitus (DM). Rates of DM and other glucose-associated disorders among HIV-positive patients have been reported to range between 2 and 14%, and in an ageing HIV-positive population, the prevalence of DM is expected to continue to increase. This study aims to develop a model to predict the short-term (six-month) risk of DM in HIV-positive populations and to compare the existing models developed in the general population. Methods All patients recruited to the Data Collection on Adverse events of Anti-HIV Drugs (D:A:D) study with follow-up data, without prior DM, myocardial infarction or other CVD events and with a complete DM risk factor profile were included. Conventional risk factors identified in the general population as well as key HIV-related factors were assessed using Poisson-regression methods. Expected probabilities of DM events were also determined based on the Framingham Offspring Study DM equation. The D:A:D and Framingham equations were then assessed using an internal-external validation process; area under the receiver operating characteristic (AUROC) curve and predicted DM events were determined. Results Of 33,308 patients, 16,632 (50%) patients were included, with 376 cases of new onset DM during 89,469 person-years (PY). Factors predictive of DM included higher glucose, body mass index (BMI) and triglyceride levels, and older age. Among HIV-related factors, recent CD4 counts of<200 cells/µL and lipodystrophy were predictive of new onset DM. The mean performance of the D:A:D and Framingham equations yielded AUROC of 0.894 (95% CI: 0.849, 0.940) and 0.877 (95% CI: 0.823, 0.932), respectively. The Framingham equation over-predicted DM events compared to D:A:D for lower glucose and lower

    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.

    This study aims to highlight the importance of screening all HIV positive women for various reproductive tract infections/sexually transmitted infections (RTIs/STIs) irrespective of symptoms and to determine its occurrence in asymptomatic HIV positive women. Relevant specimens were collected for diagnosis of various RTIs/STIs. STIs were diagnosed in nearly one-third of the HIV positive asymptomatic patients which is quite high. The national strategy for STIs/RTIs control misses out large number of asymptomatic RTIs/STIs in HIV positive women which is responsible for silently transmitting these infections in the community. So this strategy should be modified to include screening of all HIV positives women irrespective of symptoms of STIs/RTIs. PMID:26068345

    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. PMID:25941055

    Objective: As a first study, suicidal ideation and its correlates have been evaluated in Iranian HIV positive population. Methods: One hundred and fifty HIV-positive individuals were recruited in this cross-sectional study. The Hospital Anxiety and Depression Scale (HADS), Positive and Negative Suicide Ideation (PANSI), Pittsburgh Sleep Quality Inventory (PSQI) and Somatization subscale of Symptom Checklist 90 (SCL 90) as self- reported questionnaires were used to assess the patients’ anxiety and depression status, suicidal thoughts, sleep quality and physiological factors, respectively. Results: Antiretroviral therapy and efavirenz intake did not show any significant effects on the patients’ suicidal ideation. Anxiety (p<0.001), depression (p<0.001), poor physical activity (P<0.001) and sleep quality (p<0.001) were significantly associated with the patients’ negative suicidal ideation. From the patients’ demographic data, unemployment (p = 0.04), living alone (p = 0.01), and lack of family support (p = 0.01) were correlated with the patients’ negative suicidal thoughts. Conclusion: Although hospitals are the main referral centers for providing care for HIV-positive individuals in Tehran, Iran, conducting a multi-center study with sufficient sample size from different areas of our country that include individuals with different behaviors and cultures is essential to confirm the results of this study.

    Introduction Although antiretroviral therapy (ART) has been rapidly scaled up in Asia, most HIV-positive patients in the region still present with late-stage HIV disease. We aimed to determine trends of pre-ART CD4 levels over time in Asian HIV-positive patients and to determine factors associated with late ART initiation. Methods Data from two regional cohort observational databases were analyzed for trends in median CD4 cell counts at ART initiation and the proportion of late ART initiation (CD4 cell counts <200 cells/mm3 or prior AIDS diagnosis). Predictors for late ART initiation and mortality were determined. Results A total of 2737 HIV-positive ART-naïve patients from 22 sites in 13 Asian countries and territories were eligible. The overall median (IQR) CD4 cell count at ART initiation was 150 (46–241) cells/mm3. Median CD4 cell counts at ART initiation increased over time, from a low point of 115 cells/mm3 in 2008 to a peak of 302 cells/mm3 after 2011 (p for trend 0.002). The proportion of patients with late ART initiation significantly decreased over time from 79.1% before 2007 to 36.3% after 2011 (p for trend <0.001). Factors associated with late ART initiation were year of ART initiation (e.g. 2010 vs. before 2007; OR 0.40, 95% CI 0.27–0.59; p<0.001), sex (male vs. female; OR 1.51, 95% CI 1.18–1.93; p=0.001) and HIV exposure risk (heterosexual vs. homosexual; OR 1.66, 95% CI 1.24–2.23; p=0.001 and intravenous drug use vs. homosexual; OR 3.03, 95% CI 1.77–5.21; p<0.001). Factors associated with mortality after ART initiation were late ART initiation (HR 2.13, 95% CI 1.19–3.79; p=0.010), sex (male vs. female; HR 2.12, 95% CI 1.31–3.43; p=0.002), age (≥51 vs. ≤30 years; HR 3.91, 95% CI 2.18–7.04; p<0.001) and hepatitis C serostatus (positive vs. negative; HR 2.48, 95% CI 1.−4.36; p=0.035). Conclusions Median CD4 cell count at ART initiation among Asian patients significantly increases over time but the proportion of patients with late

    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

    ABSTRACT OBJECTIVE To determine the rate of cervical screening among HIV-positive women who received care at a tertiary care clinic, and to determine whether screening rates were influenced by having a primary care provider. DESIGN Retrospective chart review. SETTING Tertiary care outpatient clinic in Ottawa, Ont. PARTICIPANTS Women who were HIV-positive receiving care at the Ottawa Hospital General Campus Immunodeficiency Clinic between July 1, 2002, and June 30, 2005. MAIN OUTCOME MEASURES Whether patients had primary care providers and whether they received cervical screening. We recorded information on patient demographics, HIV status, primary care providers, and cervical screening, including date, results, and type of health care provider ordering the screening. RESULTS Fifty-eight percent (126 of 218) of the women had at least 1 cervical screening test during the 3-year period. Thirty-three percent (42 of 126) of the women who underwent cervical screening had at least 1 abnormal test result. The proportion of women who did not have any cervical tests performed was higher among women who did not have primary care providers (8 of 12 [67%] vs 84 of 206 [41%]; relative risk 1.6, 95% confidence interval 1.06 to 2.52, P < .05), although this group was small. CONCLUSION Despite the high proportion of abnormal cervical screening test results among HIV-positive women, screening rates remained low. Our results support our hypothesis that those women who do not have primary care providers are less likely to undergo cervical screening. PMID:21375064

    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

    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

    Patients who lack capacity and lack surrogates are among the most vulnerable patients we care for in palliative care. In the case we present here, we have considered how to make end-of-life decisions for a patient who lacks both capacity and surrogates, who has a terminal illness, and who is not a candidate for disease-modifying treatments. We first define and characterize this population of patients through a review of the literature and then explore some decision-making quandaries that are encountered at the end of life. Finally, we make recommendations on how best to proceed with decision making for this vulnerable population. PMID:24709366

    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

    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 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

    The first six months of HIV care and treatment are very important for long-term outcome. Early mortality (within 6 months of care initiation) undermines care and treatment goals. This study assessed the temporal distribution in baseline characteristics and early mortality among HIV patients at the University College Hospital, Ibadan, Nigeria from 2006-2013. Factors associated with early mortality were also investigated. This was a retrospective analysis of data from 14 857 patients enrolled for care and treatment at the adult antiretroviral clinic of the University College Hospital, Ibadan, Nigeria. Effects of factors associated with early mortality were summarised using a hazard ratio with a 95% confidence interval obtained from Cox proportional hazard regression models. The mean age of the subjects was 36.4 (SD=10.2) years with females being in the majority (68.1%). While patients' demographic characteristics remained virtually the same over time, there was significant decline in the prevalence of baseline opportunistic infections (2006-2007=55.2%; 2011-2013=38.0%). Overall, 460 (3.1%) patients were known to have died within 6 months of enrollment in care/treatment. There was no significant trend in incidence of early mortality. Factors associated with early mortality include: male sex, HIV encephalopathy, low CD4 count (< 50 cells), and anaemia. To reduce early mortality, community education should be promoted, timely access to care and treatment should be facilitated and the health system further strengthened to care for high risk patients.

    Arginase I (Arg I) and inducible nitric oxide synthase (iNOS) are important in regulating immune functions through their metabolites. Previous studies have revealed that the expression of Arg I is increased and the expression of iNOS is reduced in the serum and peripheral blood mononuclear cells of human immunodeficiency virus (HIV)-infected patients. As one of the most important immune organs and HIV replication sites, whether similar changes are present in the lymph nodes following HIV infection remains to be elucidated. To investigate this, the present study collected lymph node and blood specimens from 52 HIV-infected patients to measure the expression levels of Arg I and iNOS by immunohistochemistry and fluoresence-based flow cytometry. Compared with control subjects without HIV infection, the patients with HIV had significantly higher expression levels of Arg I in the lymph nodes and higher frequencies of Arg I+ CD4+ T cells and CD8+ T cells in the blood and lymph nodes, and these results were contrary the those of iNOS in the corresponding compartments. The expression levels of Arg I in the lymph nodes and blood were negatively associated with peripheral CD4+ T cell count and positively associated with viral load. However, the expression levels of iNOS in the lymph nodes and blood were positively associated with peripheral CD4+ T cell count and negatively associated with viral load. These results showed that alterations in the expression levels of Arg I and iNOS in the peripheral T cells and peripheral nodes of HIV infected patients are associated with disease progression in these patients. These results indicate a potential to therapeutic strategy for delaying disease progression through regulating and manipulating the expression levels of Arg I and iNOS in patients infected with HIV.

    Objective To assess implementation of provider-initiated testing and counseling (PITC) for HIV in Malawi. Methods 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 program data. Results 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% (5,293/5,615) of patients at tuberculosis clinics, 92.6% (30,675/33,142) of patients at antenatal clinics, and 49.4% (6,871/13,914) 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 counselors (32/71) while providers from inpatient units cited the inability to test on weekends. Conclusions 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 routine PITC is feasible. These results underscore the need to develop clear, standardized PITC policy and protocols, and to address obstacles of limited health commodities, infrastructure, and human resources. PMID:26806378

    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 hypothesis of the present study is that the polymorphisms in the APOC3, CEPT, ACE, and ACTN3 genes can affect the outcome of nutritional intervention and the plasma lipid profile of HIV+ patients. To test the hypothesis, genetic material was collected from buccal cells, and serum was collected for biochemical analysis. Sixty-five patients were analyzed. The incorporation of protease inhibitor (PI) was more frequent in women (77% vs 33% in men). Nutritional intervention improved anthropometric parameters independent of the genotype. Patients with the RR genotype for the ACTN3 R577X polymorphism had lower glycemia (RR = 95.4 ± 6.5 mg/dL, RX = 102.6 ± 10.6 mg/dL, XX = 110.1 ± 16.3 mg/dL; P = .03) and a greater reduction in low-density lipoproteins (LDL) after intervention (LDL: RR = -23.7 ± 15.8 mg/dL, RX = 1.32 ± 5.13 mg/dL, XX = 30.21 ± 24.4 mg/dL; P = .01). Patients using PI had a negative response to dietary intervention regarding the levels of high-density lipoprotein (-2.4 ± 1.70 with PI, 2.56 ± 1.60 mg/dL without PI; P = .02), very low density lipoprotein (0.84 ± 2.73 with IP, -5.46 ± 3.37 mg/dL without PI; P = .03), and triglycerides (1.79 ± 13.22 with PI, -34.00 ± 17.67 mg/dL without PI; P = .052). This response was also independent of the genotype (P > 0.05) and suggested the need for oral lipid-lowering drugs in all HIV+ patients using PI. Our results indicate that the ACTN3 R577X polymorphism is a good predictor of both the lipid profile and the prognosis of nutritional intervention in reducing LDL in HIV+ patients. PMID:27188902

    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. PMID:26545568

    Introduction 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. Methods 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. Results 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. Conclusions 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

    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.

    2011-01-01

    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

    Background Sexually transmitted infections (STI) may directly increase the risk of HIV infection, or may indicate sexual practices that increase the risk of HIV infection. In persons with HIV they probably also increase the infectiousness of HIV, even in the context of treatment with antiretroviral drugs (ARV). Estimating STI in this group has proved problematic, and there are few longitudinal studies able to accurately measure incidence. Methods In 2010, we established a cohort of individuals from ten widely dispersed sexual health clinics that were already enrolled in the Australian HIV Observational Database (AHOD). We calculated retrospective diagnosis rates for four STI (chlamydia, gonorrhoea, infectious syphilis, anogenital warts) from 2005-2010, and prospective incidence rates from 2010-2011. Results At baseline (2010) , the patient characteristics (n=554) were similar to the rest of AHOD (n=1767), namely they were predominantly male, homosexual, middle-aged, and pre- treated with ARV. Overall, the incidence of any STI was 12.5/100 person years (py). There was a gradual increase in chlamydial infections , from 3.4/100 py (95% CI 1.9-5.7) in 2005 to 6.7/100py (95% CI 4.5-9.5) in 2011, with a substantial peak of 8.1/100py (95% CI 5.6-11.2) in 2010. The cases were distributed between rectal ( 61.9%), urethral (34%), and pharyngeal (6.3%) sites. Similarly, gonococcal infections increased, with a peak in 2010 of 4.7/100py (95% CI 5.6-11.2), (p value for trend=0.0099), distributed between rectal (63.9%), urethral (27.9%), and pharyngeal (14.8%) sites. Infectious syphilis showed several peaks, the largest in 2008 (5.3/100py , (95% CI 3.3-8.0), but the overall trend was not significant (p=0.113). Diagnoses of genital warts declined from 7.5/100py (95% CI 4.8-11.3) in 2005 (95% CI 4.8-11.3) to 2.4/100py (95% CI 1.1-4.5) in 2011 (p value for trend=0.0016). Conclusions The incidence of chlamydial and gonococcal infections in this cohort was higher than previous

    Background 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. Methods 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. Results 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. Conclusions 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. PMID:26599971

    Globally, suicide and HIV/AIDS remain two of the greatest healthcare issues, particularly in low- and middle-income countries. Several studies have observed a relationship between suicidal behaviour and HIV/AIDS. Materials and Methods. The main objective of this research was to determine the prevalence of elevated risk of suicidal ideation in HIV-positive persons immediately following voluntary HIV counselling and testing (VCT). The study sample consisted of adult volunteers attending the VCT clinic at a university-affiliated, general state hospital. Participants completed a sociodemographic questionnaire, Beck's Hopeless Scale, and Beck's Depression Inventory. Results. A significantly elevated risk of suicidal ideation was found in 83.1% of the patients who tested seropositive. Despite a wide age range in the cohort studied, the majority of patients with suicidal ideation were males in the younger age group (age < 30 years), consistent with the age-related spread of the disease and an increase in suicidal behaviour in younger people. Relevant associated variables are discussed. Conclusion. The results serve as important markers that could alert healthcare professionals to underlying suicide risks in HIV-positive patients. It is recommended that screening for elevated risk of suicidal ideation and prevention of suicidal behaviour should form a routine aspect of comprehensive patient care at VCT clinics. PMID:26491561

    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.

    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

    The association between abnormal cervical cytology and HIV infection status in women was evaluated to correlate with CD4 cell count and viral load in HIV-positive patients with the presence of low-grade (LSIL) and high-grade squamous intraepithelial lesion (HSIL). Cervical samples were collected at the Tropical Disease Hospital, Maternal and Child Healthcare Hospital and at the Nascer Cidadão Maternity Hospital in Goiânia, Goiás, Brazil. An Ayre's spatula was used to collect samples from the ectocervix and a cytology brush to collect samples from the endocervix. Of a total of 237 women, 125 were HIV positive and 112 were HIV negative. Abnormal cytology (n = 21; 8.9%) was more common in the HIV positive group (n = 15; 12.1%) compared to the HIV-negative group (n = 6; 5.4%) (P = 0.05). Cytological abnormalities were not found to be associated with immunosuppression, defined as CD4 count < 200 cells/mm3. A higher frequency was found between higher viral loads (>10,000/mm3) and the presence of abnormal cytology. Pregnant women, irrespective of whether they were HIV positive or negative, were less likely to have lesions compared to the nonpregnant women in the same groups. The higher frequency of abnormal findings in Papanicolaou cytology in HIV-positive women with higher viral loads suggests the association between preinvasive cervical lesions and human immunodeficiency.

    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.

    HIV-positive lactating women may be at high risk of weight loss due to increased caloric requirements and postpartum physiological weight loss. Ten percent weight loss is associated with a higher risk of mortality in HIV-positive patients and this alone is a criterion for highly active antiretroviral therapy (HAART) initiation where CD4 counts are not available. However, no study has investigated this association in lactating postpartum women. We investigated whether 10% weight loss predicts death in postpartum HIV-positive women. A total of 9207 HIV-negative and 4495 HIV-positive mothers were recruited at delivery. Women were weighed at 6 weeks, 3 months, and every 3 months thereafter for up to 24 months postpartum and data on mortality up to 2 years were collected. The median duration of breastfeeding was longer than 18 months. Among HIV-positive women, the independent predictors of ≥10% weight loss were CD4 cell count, body mass index, and household income. Mortality was up to 7.12 (95% CI 3.47-14.61) times higher in HIV-positive women with ≥10% weight loss than those without weight loss. Ten percent weight loss in postpartum lactating HIV-positive women was significantly predictive of death. Our findings suggest that 10% weight loss is an appropriate criterion for HAART initiation among postpartum breastfeeding women. PMID:21226627

    The objective of this study was to assess the perceptions of Malaysian HIV-positive subjects towards the attitude of dental personnel in providing oral care to them. The study design was cross-sectional with the sampling frame comprising of 27 Government Drug Rehabilitation Centres throughout Malaysia. A convenience sample was then taken from 20 centres with the highest enrolment of HIV-positive subjects. A self-administered questionnaire was used to elicit information on the perception of HIV-positive subjects towards the attitude of dental personnel in providing oral care to the patient with HIV-positive. The study sample consisted of 509 HIV-positive individuals with a mean age of 31.3+/-12.9 years old. Of these, only 15.1% attended a dental clinic after confirmation of HIV-positive status. The study demonstrated that 67.5% of the HIV-positive subjects disclosed their status voluntarily to the dentists and majority of the dentists (76.9%) did not show any negative reaction on knowing their HIV positive status. There was also no difference in the attitude of auxiliary staff toward the above disclosure. In conclusion, the study showed that oral health care personnel are more receptive to the HIV-positive subjects receiving dental care and treatment. PMID:16044826

    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. PMID:26782408

    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

    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.

    Context: Tamil Nadu comes under group I high prevalence state, with less than 1% prevalence of HIV infection in antenatal women but above 5% prevalence in high risk group. One of the ways to control HIV/AIDS in India is through Prevention of Parent to Child Transmission (PPTCT), the success of which lies in identifying pregnant women with HIV infection. But due to the stigma against HIV/AIDS among health care providers, HIV positive patients face discrimination in the health sector. Aims: To explore the difficulties faced by rural HIV positive mothers during the intra-natal period. Methods: A descriptive qualitative study was conducted among HIV positive mothers, in Gingee block of Villupuram district, Tamil Nadu, India. All the mothers who tested positive between June 2006 and May 2010 were interviewed in-depth using an interview guide. Results: There were 21 HIV positive mothers during this period, 19 of whom gave consent. Majority of the mothers were <30 years of age from families belonging to lower socio-economic class. The discriminations faced from the health staff was avoidance of physical examination, rude behaviour like throwing of records on the face, discriminatory comments, unnecessary referrals and even refusal to provide intra-partum services. The negative attitude of the staff made a few mothers to deliver in some other institution without disclosing their HIV status. Conclusion: Stigma among health care providers towards HIV positive pregnant women acts as a barrier for improving access to PPTCT services in India and it poses high risk to the mothers, babies and also the health care providers. There is a pressing need to improve access to quality PPTCT services especially during the intranatal period. PMID:24298476

    Fibroblast growth factor23 (FGF23), an early marker of kidney dysfunction, is associated with cardiovascular death. Its role in HIV-positive individuals is unknown. We measured FGF23 in 100 HIV-negative and 191 HIV-positive nondiabetic adults with normal baseline estimated glomerular filtration rate (GFR). We measured GFR by iohexol annually, albumin-creatinine ratio (ACR) every 6 months, as well as pulse wave velocity, carotid plaque, and carotid intima media thickness (IMT) at baseline and 2 years. Progressive albuminuria was defined as follow-up ACR ≥2-fold than baseline and ≥30 mg/g. Regression models assessed associations of FGF23 with baseline factors and longitudinal changes in disease markers. FGF23 levels were similar in HIV serostatus. Among HIV-positive persons, factors independently associated with higher baseline FGF23 levels included female (adjusted ratio of geometric means [95% CI],1.46 [1.21,1.76]), serum phosphorus (1.20 [1.03,1.40]), HCV (1.31 [1.10,1.56]) and non-suppressed HIV RNA (1.27 [1.01,1.76]). At baseline, FGF23 was not associated with GFR, albuminuria, carotid plaque, or carotid IMT in cross-sectionally adjusted analysis of HIV-positive individuals. However, higher baseline FGF23 was associated with progressive albuminuria (odds ratio1.48 [95% CI]:1.05,2.08) and a more rapid increase in IMT (13 μm/year, 95% CI,3,24). These findings suggest a role for FGF23 in HIV-positive populations in identifying patients at greater risk for cardiovascular and kidney disease. PMID:27176000

    Race, HIV, and incarceration, as individual and intersecting markers of social identity, have associated stigma. While some research has indicated multiple burdens of stigma can be additive, there remains a lack of investigation relative to the effects of stigma among minorities who experience both HIV and incarceration. Therefore, the current study examines the impact of multiple forms of stigma via a series of ethnographic interviews (n = 46) conducted with 12 African American men over a one-year period. Results suggest that intersecting forms of stigma can have a severe impact on the general health, mental health, and the reintegration process of formerly incarcerated HIV-positive men. Additionally, participants often conceptualized all forms of stigma separately, which resulted in compounded burden of navigation. The experience of multiple forms of stigma was also often internalized as self-stigma whereby HIV-positive individuals with a history of incarceration assumed dominant norms related to both HIV and incarceration.

    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. PMID:25164924

    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.

    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. PMID:26764909

    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.

    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

    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.

    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. PMID:23991691

    Background Sex workers and HIV seropositive women are at high risk of abnormal cervical cytology. The objective of this study was to compare the cervical cytology among three groups of women: active sex workers, HIV-infected women, and general population in Iran. Methods This was a cross-sectional study performed in Hazrat Zeinab, Lavan clinics and drop in center (DIC) in Shiraz, Iran. This study was performed from October 2009 to October 2011. A total of 266 patients were assigned into three groups: sex-workers (85), HIV positive patients (100), and general population (81). Pap smear was performed for all participants from the exocervix and endocervix, using a plastic Ayres’s spatula and cytobrush. The samples were sent to a pathology center, using a liquid-based media.  Results The risk of cervical infection in sex workers and HIV positive women was greater than the general population (OR=5.47, 95% confidence interval [CI]:2.24, 13.40), (OR=3.71, 95% CI:1.52, 9.09), respectively. The frequency of abnormal cervical cytology in the HIV positive and sex worker groups was higher than the general population (OR=6. 76, 95% CI:2.25, 20.32), (OR=3. 80, 95% CI:1.19, 12.07), respectively. Low-grade squamous intraepithelial lesion (LSIL) and high-grade squamous intraepithelial lesion (HSIL) were associated with CD4 cell count<200Í106/L, P=0.021 and P<0.001, respectively. Conclusion Vaginal infections were seen more often in the sex worker group, and abnormal cervical cytology was greater in the HIV positive group. PMID:26005687

    1997-01-01

    This paper examines psychotherapy with HIV-positive gay men from a psychodynamic perspective. Adjustment to being HIV-positive is conceptualized as an ongoing process of confrontation with loss and uncertainty. Interventions offered to HIV-positive gay men range from counseling, indicated in response to an "uncomplicated" adjustment process; to dynamically oriented psychotherapy, indicated when the functioning of the self has been thrown off balance by HIV illness. The client's process of accepting his HIV illness is shaped and colored by the degree to, and manner in, which he has accepted being gay and integrated this into his identity. Sexuality is a core theme in psychotherapy with this population. It often plays a prominent role in the past unresolved conflicts (feelings about having become HIV-infected) as well as present concerns (feelings about living with HIV illness) which the client has come to therapy to address. The process of addressing the meanings being HIV-positive holds for the client in therapy can promote acceptance of the illness and cohesiveness of the self. Cultural and subcultural differences in how life stress is experienced must also be taken into account by the therapist in order to fully appreciate the client's concerns. PMID:9139546

    Prevention and cessation of Tobacco use among persons living with HIV/AIDS (PLWHA) represents a significant challenge for HIV/AIDS patient care in China and across the globe. Awareness of HIV-positive status may alter the likelihood for PLWHA smokers to change their smoking habit. In this study, we tested the risk enhancement and risk reduction hypotheses by assessing changes in cigarette smoking behavior among PLWHA after they received the positive results of their HIV tests. Cross-sectional survey data collected from a random sample of 2973 PLWHA in care in Guangxi, China were analyzed. Changes in cigarette smoking after receiving the HIV-positive test results, as well as the current levels of cigarette smoking were measured. Among the total participants, 1529 (51.7%) were self-identified as cigarette smokers, of whom 436 (28.9%) reduced smoking and 286 (19.0%) quit after receiving their HIV-positive test results. Among the quitters, 210 (73.9%) remained abstinent for a median duration of two years. There were also 124 (8.2%) who increased cigarette smoking. Older age, female gender, more education, and receiving antiretroviral therapy were associated with quitting. In conclusion, our study findings support the risk reduction and risk enhancement hypotheses. A large proportion of smoking PLWHA reduced or quit smoking, while a small proportion increased smoking. Findings of this study suggest that the timing when a person receives his or her HIV-positive test result may be an ideal opportunity for care providers to deliver tobacco cessation interventions. Longitudinal studies are indicated to verify the findings of this study and to support smoking cessation intervention among PLWHA in the future. PMID:26457812

    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.

    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

  15. “Silent Voices”: A Description of Views and Attitudes of Health Professionals towards Reproduction by HIV Positive People

    2014-01-01

    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

    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

    In the context of the African HIV epidemic, support groups are not simply spaces for discussions of social and health well-being; neither are they institutions functioning solely to cultivate self-responsible and economically empowered patients. HIV-positive women in northern Nigeria have appropriated a support group to facilitate their marriage arrangements. In this group, women negotiate the threats of stigma and the promises of respectable marriage through what I call the management of ambiguity surrounding their HIV status. I further argue that the practice of support group matchmaking reveals the local political economic dynamics that shape social and illness trajectories in resource-poor settings. PMID:23946544

    Recurrent Sexually Transmitted Infections (STIs) are an indication of unsafe sexual practices and may be associated with HCV-infection among HIV-positive men who have sex with men. In a retrospective study we analysed the laboratory data of 99 HIV-positive MSM who acquired HCV during the observation period (cases) and 176 HIV-positive MSM who remained HCV negative during the observation period (controls), all followed at the HIV/STI-clinic in Antwerp, Belgium. All laboratory confirmed STI-episodes were recorded since the date of first consultation at our clinic, until the date of HCV-diagnosis of the cases. The HCV incidence varied between 0.24 (2001) and 1.36 (2011) new cases per hundred person-years, with a peak of 2.93 new cases per hundred person-years in 2009. The number of STI-episodes per person-year follow-up was significantly higher for the cases as compared to the controls for syphilis, non-LGV and LGV Chlamydia infections (p < 0.005). When considering the incidence of STIs that occurred 1 year prior to HCV conversion, all laboratory confirmed STIs remained more frequent among cases, but only the difference in syphilis incidence was statistically significant (p < 0.01). Recurrent STIs among HIV positive MSM should be considered as a behavioural and biological risk factor for acquiring HCV and should lead to intensified screening for HCV and counselling of the patient.

    For some patient subgroups, human immunodeficiency virus (HIV) infection has been associated with worse outcomes after kidney transplantation (KT); potentially modifiable factors may be responsible. The study goal was to identify factors that predict a higher risk of graft loss among HIV-positive KT recipients compared with a similar transplant among HIV-negative recipients. In this study, 82 762 deceased donor KT recipients (HIV positive: 526; HIV negative: 82 236) reported to the Scientific Registry of Transplant Recipients (SRTR) (2001-2013) were studied by interaction term analysis. Compared to HIV-negative recipients, the hepatitis C virus (HCV) amplified risk 2.72-fold among HIV-positive KT recipients (adjusted hazard ratio [aHR]: 2.72, 95% confidence interval [CI]: 1.75-4.22, p < 0.001). Forty-three percent of the excess risk was attributable to the interaction between HIV and HCV (attributable proportion of risk due to the interaction [AP]: 0.43, 95% CI: 0.23-0.63, p = 0.02). Among HIV-positive recipients with more than three HLA mismatches (MMs), risk was amplified 1.80-fold compared to HIV-negative (aHR: 1.80, 95% CI: 1.31-2.47, p < 0.001); 42% of the excess risk was attributable to the interaction between HIV and more than three HLA MMs (AP: 0.42, 95% CI: 0.24-0.60, p = 0.01). High-HIV-risk (HIV-positive/HCV-positive HLAwith more than three MMs) recipients had a 3.86-fold increased risk compared to low-HIV-risk (HIV-positive/HCV-negative HLA with three or fewer MMs)) recipients (aHR: 3.86, 95% CI: 2.37-6.30, p < 0.001). Avoidance of more than three HLA MMs in HIV-positive KT recipients, particularly among coinfected patients, may mitigate the increased risk of graft loss associated with HIV infection. PMID:27140837

    Background The purpose of the study was to examine whether early repeated infections due to Trichomonas vaginalis among human immunuodeficiency virus (HIV)–positive and HIV-negative women are reinfections, new infections, or cases of treatment failure. Methods Women attending an HIV outpatient clinic and a family planning clinic in New Orleans, Louisiana, who had culture results positive for T. vaginalis were treated with 2 g of metronidazole under directly observed therapy. At 1 month, detailed sexual exposure and sexual partner treatment information was collected. Isolates from women who had clinical resistance (i.e., who tested positive for a third time after treatment at a higher dose) were tested for metronidazole susceptibility in vitro. Results Of 60 HIV-positive women with trichomoniasis, 11 (18.3%) were T. vaginalis positive 1 month after treatment. The 11 recurrences were classified as 3 probable reinfections (27%), 2 probable infections from a new sexual partner (18%), and 6 probable treatment failures (55%); 2 of the 6 patients who experienced probable treatment failure had isolates with mild resistance to metronidazole. Of 301 HIV-negative women, 24 (8.0%) were T. vaginalis positive 1 month after treatment. The 24 recurrences were classified as 2 probable reinfections (8%) and 22 probable treatment failures (92%); of the 22 patients who experienced probable treatment failure, 2 had strains with moderate resistance to metronidazole, and 1 had a strain with mild resistance to metronidazole. Conclusion HIV-positive women were more likely to have sexual re-exposure than were HIV-negative women, although the rate of treatment failure was similar in both groups. High rates of treatment failure among both HIV-positive and HIV-negative women indicate that a 2-g dose of metronidazole may not be adequate for treatment of some women and that rescreening should be considered.

    Introduction Injecting drug use (IDU) is associated with tuberculosis but few data are available from low-income settings. We examined IDU in relation to active and latent tuberculosis (LTBI) among HIV-positive individuals in Indonesia, which has a high burden of tuberculosis and a rapidly growing HIV epidemic strongly driven by IDU. Methods Active tuberculosis was measured prospectively among 1900 consecutive antiretroviral treatment (ART)-naïve adult patients entering care in a clinic in West Java. Prevalence of LTBI was determined cross-sectionally in a subset of 518 ART-experienced patients using an interferon-gamma release assay. Results Patients with a history of IDU (53.1%) more often reported a history of tuberculosis treatment (34.8% vs. 21.9%, p<0.001), more often received tuberculosis treatment during follow-up (adjusted HR=1.71; 95% CI: 1.25–2.35) and more often had bacteriologically confirmed tuberculosis (OR=1.67; 95% CI: 0.94–2.96). LTBI was equally prevalent among people with and without a history of IDU (29.1 vs. 30.4%, NS). The risk estimates did not change after adjustment for CD4 cell count or ART. Conclusions HIV-positive individuals with a history of IDU in Indonesia have more active tuberculosis, with similar rates of LTBI. Within the HIV clinic, LTBI screening and isoniazid preventive therapy may be prioritized to patients with a history of IDU. PMID:25690530

    Purpose Atypical antipsychotics (AAs), an effective treatment for schizophrenia, have a range of pharmacologic properties leading to differences in tolerability as well as heterogeneity in treatment response. Individual patient characteristics must be considered when making treatment choices, especially from an adverse event (AE) or tolerability perspective. Despite the availability of numerous AAs, after appraising patient characteristics at the time of treatment selection, physicians may quickly run out of tolerable treatment options. Patients and methods AE risk factors, defined as having either a prior history of an AE or a risk factor for that AE, were determined for Medicaid-insured and Commercially insured patients using database analysis. Patients receiving AA treatment between January 1, 2010 and December 31, 2012 defined the index date of first observed AA prescription during this period. Nine AAs were evaluated for association with AE risk factors as informed by drug prescribing information from the different manufacturers and published meta-analyses. The proportion of patients with pre-index AE risk factors prescribed an AA associated with that risk factor was then determined. Results A high proportion of patients (>80%) were prescribed an AA associated with extrapyramidal symptoms or akathisia despite experiencing extrapyramidal symptoms or akathisia prior to AA treatment initiation. Similar trends were observed among patients with diabetes (>60%) and obesity (>40%). From the nine treatment options available, the number of optimal choices for individual patient segments were limited based on their prior history, including those with cardiometabolic and cardiovascular comorbidities (four); experiencing prolactin elevation-related problems (seven); needing to avoid excessive sedation (four); or at risk of extrapyramidal symptoms or akathisia (two). Options were then further restricted among patients in more than one segment when multiple pre-index AE

    Videorecording of patients requires the utmost respect for the privacy and confidentiality of the patients. Consent should be requested from patients for all videorecording. When a mental disability or mental or physical illness prevents patients from giving their permission, agreement to recording from a legal representative or from a close relative or carer are necessary. Three documents on this subject issued in the United Kingdom, the United State of America and Italy are briefly summarized and discussed. The problem of consent for videorecording is addressed particularly in reference to persons incapable of making decisions on their own, such as persons in vegetative state. The general ethical framework is outlined and a few practical proposals are given. PMID:21952148

    The colonization by Candida species is one of the most important factors related to the development of oral candidiasis in HIV-infected individuals. The aim of the study was to evaluate and discuss the phospholipase, proteinase, DNAse and haemolytic activities of Candida albicans isolated from the oral cavity of HIV individuals with high efficiency antiretroviral therapy. Seventy-five isolates of C. albicans obtained from saliva samples of patients with HIV and 41 isolates from HIV-negative individuals were studied. Haemolytic activity was determined in Sabouraud dextrose agar plates containing 3% glucose and 7% sheep red cells. Culture medium containing DNA base-agar, egg yolk, and bovine albumin were used to determine DNase, phospholipase and proteinase activities, respectively. All isolates from the HIV patients group had haemolytic activity, 98% showed phospholipase activity, 92% were positive for proteinase and 32% DNAse activity. Regarding the group of indivídios HIV negative, all 41 isolates presented hemolytic activity, 90.2% showed phospholipase and proteinase activity and 12.2% were positive for DNAse. The phospholipase activity was more intense for the group of HIV positive individuals. DNase production was more frequently observed in the group of HIV-positive individuals. The percentage of isolates having DNAse activity was also significantly different between the groups of patients not using any antiretroviral therapy, those using transcriptase inhibitors and those using transcriptase inhibitor and protease inhibitor in combination.

    Background & objectives: India has the third highest burden of HIV and highest number of cervical cancer in the world. A cross-sectional study was performed to determine the prevalence and types of human papillomavirus (HPV) infection, and the factors associated with HPV infection and abnormal cervical cytology in HIV-positive women attending the Antiretroviral Therapy (ART) Centre in a tertiary care hospital in eastern India. Methods: We screened 216 HIV- positive women with Papanicolau smear cytology and HPV testing. HPV DNA was detected by using consensus primers followed by sequencing. Results: Of the 216 HIV-positive women screened, 58 (26.85%) were HPV-positive; 56 (25.9%) were of high-risk (HR) HPV type. The most prevalent HPV type was HPV-16 (7.9%); non 16 and 18 HPV types were present in 17.6 per cent patients. Age ≤ 35 yr [(OR), 2.56 (1.26-5.19)], illiteracy [OR, 2.30 (1.19-4.46)], rural residence [OR, 3.99 (1.27-12.56)] and CD4 ≤350/μl [OR, 2.46 (1.26-4.83)] were associated with increased risk of acquisition of HPV. One hundred thirty nine (74.33%) patients had normal/ negative for intraepithelial lesions (NILM) cytology, three (1.60%) had atypical squamous cells of undetermined significance (ASCUS), 32 (17.11%) had low-grade squamous intraepithelial lesions (LSIL), 10 (5.35%) had high-grade squamous intraepithelial lesions (HSIL) and three (1.60%) had carcinoma cervix. WHO clinical Stage III and IV [OR, 2.83 (1.07-7.49)] and CD4 ≤350/μl [OR, 2.84 (1.30-6.20)] were risk factors for abnormal cytology. Interpretation &conclusions: Our study showed 26.85 per cent HPV positivity in HIV infected women in this region, with HPV-16 as the commonest genotype. Abnormal cervical cytology was seen in about 25 per cent women. Regular Pap smear screening as recommended by the National AIDS Control Organization will help in early detection of cervical abnormalities in HIV- positive women. PMID:26997018

    Health maintenance (HM) practices are essential to prevent illness, promote well-being, and maximize health. Patients with multiple myeloma (MM) are at increased risk for cardiovascular disease and cancers, yet, research on HM practices and preventative care of MM survivors has limited report. The study comprised a descriptive, correlational, and cross-sectional online survey design. Survey of patients with MM was carried out through the International Myeloma Foundation (IMF) and the Association of Cancer Online Resources (ACOR) e-mail list services. The members of the IMF and ACOR e-mail list services were surveyed, of which 237 patients responded. The modified Medical Expenditure Preventive Survey-Preventive Care questionnaire was used; it included items that ask patients regarding their healthcare practices that relate to dental care, cancer prevention, addiction, lifestyles, sensory screening, immunizations, cardiovascular, endocrine, psychosocial, and bone health. Descriptive statistics, Pearson's chi-square, and Spearman's rho correlation coefficient were obtained. In this study, men had statistically significant inferior global health maintenance scores than women (P = 0.002). Being employed (P = 0.054) and married or partnered (P = 0.017) were significantly correlated with better health maintenance patterns among male respondents. In contrast, no statistically significant correlations between sociodemographic factors and health maintenance patterns were found in women. Patients with MM, particularly men, require continued education and close monitoring of health maintenance practices. These findings are consistent with publications looking at gender disparities in healthcare utilization in the United States. Studies show that men, in general, are less likely to seek preventative healthcare screenings. Healthcare providers must incorporate health maintenance promotion during clinic visits. PMID:27119422

    Rates of depression are high among individuals living with HIV. Accurate assessment of depressive symptoms among this population is important for ensuring proper diagnosis and treatment. The Beck Depression Inventory-II (BDI-II) is a widely used measure for assessing depression, however its psychometric properties have not yet been investigated for use with HIV-positive populations in the United States. The current study was the first to assess the psychometric properties of the BDI-II among a large cohort of HIV-positive participants sampled at multiple sites across the United States as part of the CNS HIV Antiretroviral Therapy Effects Research (CHARTER) study. The BDI-II test scores showed good internal consistency (α = .93) and adequate test-retest reliability (internal consistency coefficient = 0.83) over a 6-mo period. Using a "gold standard" of major depressive disorder determined by the Composite International Diagnostic Interview, sensitivity and specificity were maximized at a total cut-off score of 17 and a receiver operating characteristic analysis confirmed that the BDI-II is an adequate diagnostic measure for the sample (area under the curve = 0.83). The sensitivity and specificity of each score are provided graphically. Confirmatory factor analyses confirmed the best fit for a three-factor model over one-factor and two-factor models and models with a higher-order factor included. The results suggest that the BDI-II is an adequate measure for assessing depressive symptoms among U.S. HIV-positive patients. Cut-off scores should be adjusted to enhance sensitivity or specificity as needed and the measure can be differentiated into cognitive, affective, and somatic depressive symptoms. PMID:25419643

    Delayed antiretroviral initiation is associated with increased mortality, but individuals frequently delay seeking treatment. To increase early antiretroviral therapy (ART) enrollment of HIV-positive women, antenatal clinics are implementing regular, postpartum CD4 count testing. We examined factors influencing women's utilization of extended CD4 count testing. About 53 in-depth interviews were conducted with nurses, patients, social support persons, and government health officials at three antenatal clinics in Lilongwe, Malawi. Counseling and positive interactions with staff emerged as facilitating factors. Women wanted to know their CD4 count, but didn't understand the importance of early ART initiation. Support from husbands facilitated women's return to the clinic. Reminders were perceived as helpful but ineffectively employed. Staff identified lack of communication, difficulty in tracking, and referring women as barriers. Counseling messages should emphasize the importance of starting ART early. Clinics should focus on male partner involvement, case management, staff communication, and appointment reminders. Follow-up should be offered at multiple service points. PMID:21347895

    Urea is an old uremic toxin which has been used for many years as a global biomarker of CKD severity and dialysis adequacy. Old studies were not in favor of its role as a causal factor in the pathogenesis of complications associated with the uremic state. However, recent experimental and clinical evidence is compatible with both direct and indirect toxicity of urea, particularly via the deleterious actions of urea-derived carbamylated molecules. Further studies are clearly needed to explore the potential relevance of urea-related CKD complications for patient management, in particular the place of new therapeutic strategies to prevent urea toxicity.

Methods We included people enrolled in Icona with either CD4 counts ≤350 cells/mm3 (low CD4-LC) or CD4 counts ≤200 cells/mm3 (very low CD4-VLC) and/or AIDS, starting their first PI/r-based regimen after 2008. Initial regimens were compared by intention-to-treat: i) time to viral failure (VF) (first of 2 consecutive VL>200 copies/mL after≥6 months); II) time to PI/r discontinuation/switching for any cause (TD) and for toxicity (TDT); III) treatment failure (TF) (VF or TD). Kaplan-Meier and Cox analyses were used. Results 1,362 LC patients were included (DRV/r 607; ATV/r 552; LPV/r 203); 813 VLC. In a median of 18 months (IQR:7–35), the 1-year probability of VF and TF were 2.8% (1.9–3.8) and 21.1% (18.7–23.4). In the adjusted analysis, patients initiating ATV/r had a 53% lower chance, and those initiating DRV/r a 61% lower chance of TD, as compared to LPV/r; the risk of TF was more likely in people starting LPV/r. Results were similar among VLC; in this subgroup LPV/r including regimens demonstrated a lower chance of VF. Conclusions We confirmed in LC a low chance of virological failure by 1 year, with small differences according to PI/r. However, larger differences were observed when comparing longer-term endpoints such as treatment failure. These results are important for people presenting late for care. PMID:27348592

    The aim of this study was to determine the patterns of change in body fat and metabolic parameters in a South African cohort on a first line ART regimen containing stavudine. Fasting lipogram, blood glucose and insulin levels, CD4 cell count, viral load, BMI, waist-to-hip ratio (WHR), and skinfold thickness at the triceps, scapula, and iliac crest were measured before starting ART in 42 (27 female) subjects. Repeat measurements were performed at four monthly intervals for 2 years. Lipodystrophy was diagnosed using patient perception and assessment by a physician. At baseline, subjects who went on to develop lipodystrophy (LD group) were fatter and had higher skinfold thickness at all three sites and higher insulin levels than subjects who never developed lipodystrophy (NLD group). The WHR increased to a greater extent while hip circumference and tricep skinfolds fell more significantly in the LD than NLD group. Triglyceride and cholesterol levels increased significantly in both groups while lactate and glucose levels increased more and insulin levels increased less in the LD than the NLD group. Neither viral load nor CD4 count differed between the groups during the study. Viral load correlated positively with insulin levels at baseline. Thus, lipodystrophy in the South African population is characterized by a higher BMI before initiation of ART and lipoatrophy of the arms and hips, lipohypertrophy of the waist, and increased lactate production. When compared to the NLD group, the LD subjects display attenuated insulin secretory output in response to a higher weight gain. PMID:19619010

    Acquired immunodeficiency syndrome and related opportunistic infections are a significant cause of morbidity and mortality in susceptible population. This study aims to negate the paucity of data regarding the relation between CD4 levels, prevalence of enteric parasites, and the outcome of treatment with HAART (highly active antiretroviral therapy) and Cotrimoxazole in Kerala, India. Multiple stool samples from 200 patients in a cross-sectional study were subjected to microscopy and Cryptosporidium stool antigen ELISA. Parasites were identified in 18 samples (9%). Cystoisospora and Cryptosporidium spp. were seen in 9 cases (4.5%) and 5 cases (2.5%), respectively. Microsporidium spores and Chilomastix mesnili cysts were identified in 1 case each (0.5% each). Seven cases of Cystoisospora diarrhoea recovered after treatment with Cotrimoxazole. Diarrhoea due to Cryptosporidium spp. in all 5 cases subsided after immune reconstitution with HAART. This study concludes that a positive association was seen between low CD4 count (<200 cells/μL) and overall parasite positivity (P value < 0.01). ELISA is a more sensitive modality for the diagnosis of Cryptosporidium diarrhoea. Chilomastix mesnili, generally considered a nonpathogen, may be a cause of diarrhoeal disease in AIDS. Immune reconstitution and Cotrimoxazole prophylaxis remain to be the best therapeutic approach in AIDS-related diarrhoea. PMID:27493988

    A Federal jury in the court of U.S. Magistrate Judge Leslie G. Foschio of the Western District of New York found the Buffalo [name removed] liable for more than $630,000 in damages to bartender [name removed], who was fired because of his HIV infection. The [name removed] unsuccessfully argued that [name removed] was terminated because of unfavorable performance reviews. The plaintiffs claimed that the [name removed] issued false citations for infractions of hotel rules and that these citations were only issued after hotel management determined that [name removed] was HIV-positive. Testimony showed that all relevant decision-making personnel at the hotel were aware that [name removed] was HIV-positive. The hotel failed to show that all but the personnel manager had a legitimate need to know about [name removed]'s HIV status. The jury awarded [name removed] $1,439,000 in damages. Foschio lowered the amount to $637,388 in damages and $133,705 in attorneys' fees. PMID:11364135

    1999-01-01

    This article narrates the story of Peati, an HIV-positive mother who had already lost her husband and 1-year-old son to AIDS. Peati's ordeal began when her rugby-star husband Malaki tested positive 4 years after they were married in June 27, 1992. She had to endure many things, including the people's judgmental reactions towards them and the pressure from her own family who wanted her to leave her husband. Following her husband and child's deaths, she, too, tested positive for HIV. Consequently, she lost not only her job but also her family and friends, leaving her all alone to take care of her other son, Natal. Luckily, a Samoan businesswoman named Fatima Strickland offered to help her both financially and emotionally. She then decided to share her story so that others may learn from her experience. The first time she spoke was at the First Pacific Regional HIV/AIDS and STDs Conference in Fiji, where she described her personal trauma as an HIV-positive person now taking care of a 6-year-old son. Peati now works for the Ministry of Women's Affairs in Apia with a commitment to help other Samoan women understand the disease and how to protect themselves against it. PMID:12349393

    The HIV Organ Policy Equity (HOPE) Act now allows transplantation of organs from HIV-positive living and deceased donors to HIV-positive individuals with end-stage organ disease in the United States. Although clinical experience with such transplants is limited to a small number of deceased-donor kidney transplants from HIV-positive to HIV-positive persons in South Africa, unprecedented HIV-positive-to-HIV-positive liver transplantations and living-donor kidney transplantations are also now on the horizon. Initially, all HIV-positive-to-HIV-positive transplantations will occur under research protocols with safeguards and criteria mandated by the National Institutes of Health. Nevertheless, this historic change brings ethical opportunities and challenges. For HIV-positive individuals needing an organ transplant, issues of access, risk, and consent must be considered. For potential HIV-positive donors, there are additional ethical challenges of privacy, fairness, and the right to donate. Careful consideration of the ethical issues involved is critical to the safe and appropriate evaluation of this novel approach to transplantation. PMID:27043422

    Aim Human papillomavirus (HPV) is a pathogenic factor of squamous cell carcinoma in various mucosal locations, including anal carcinoma (ACA). It is also known that patients positive for HIV are at high risk of ACA. The goal of this study was to examine clinical outcome in ACA in relation to HPV/p16 positivity, histologic tumor differentiation, and HIV status. Patients with oropharyngeal cancers that are positive for HPV and show overexpression of p16 as well as having non-keratinizing/basaloid histology have been reported to have better outcomes following chemoradiation (CRT). However, such relationships in ACA remain unknown. Methods Forty-two patients with SCC of the anus treated with CRT between 1997 and 2009 were identified. The tumors were subclassified as either non-keratinizing (including basaloid) or keratinizing categories. HPV testing was performed using SPF10-PCR, and all cases were immunostained for p16. Results There were 23 men and 19 women; 43 % of men and 11 % of women were HIV-positive (p =0.04). Fifty-five percent of patients had local disease (stages I and II) and 41 % were stages III and IV, with 4 % stage unknown. All tumors were positive for high-oncogenic risk HPVs, and all were positive with p16 immunostain. Sixty-four percent of tumors were non-keratinizing/basaloid and 36 % were keratinizing. The keratinizing tumors were more common in HIV-positive patients (67 %), whereas non-keratinizing/basaloid tumors were more common in HIV-negative patients (77 %) (p =0.008). Thirty-one percent of patients had recurrence of disease, including 50 % HIV-positive patients and 23 % HIV-negative patients (p =0.09). There was no difference in the recurrence rate between non-keratinizing and keratinizing tumor subtypes (p =0.80). The 24-month recurrence-free survival for the cohort was 66 % (95 % CI=46 %, 81 %), with HIV-positive patients having worse recurrence-free survival compared to HIV-negative patients (HR=2.85, 95 % CI= 0.95, 8.53; p =0

    Introduction Every endocrine gland has been reported to be affected at varying rates in HIV. HIV is a highly stigmatized chronic disease with a substantial co-occurrence of mental and sexual health problems; however the sexual health problems in women have not been extensively studied. Aim To study the gonadal hormonal abnormalities and sexual dysfunction in HIV positive female patients and its possible association. Materials and Methods This descriptive/exploratory study was conducted in the Department of General Medicine at a tertiary care hospital from September 2013 to August 2015. The study group included 50 diagnosed HIV-positive patients. They were also subjected to specific questions regarding sexual dysfunction by female counselors using female sexual function index. Visits of the subjects were scheduled independent of the menstrual cycle. Hormonal levels (free testosterone, FSH, LH) were measured. Results Out of 50 patients, 26 patients in our study had sexual dysfunction (52%). Patients with age group between 30-39 years had the maximum sexual dysfunction compared to the other groups (<0.001). Patients with a CD4 count between 200 and 499 had the maximum sexual dysfunction (<0.02). Mean duration of HIV in the study was 30 months in sexual dysfunction group which was significant (p<0.005). Hormonal levels were found to be in normal range. All the study patients reported desire, arousal and lubrication problems whereas orgasm and satisfaction problems were noted in 60% patients with pain reported in 52%. Conclusion We identified that although the hormonal levels were in the normal range, they were comparatively in the lower range in the dysfunction group than the non-dysfunctional group. Both free testosterone and FSH levels were low indicating involvement of the pituitary rather than the gonads. We also conclude that duration of HIV and also level of CD4 count is related to sexual dysfunction. PMID:27190860

    The HIV-positive population, due to their immuno-compromised nature, is considered more susceptible to parasitic infections than other populations. However despite the reports of other opportunistic pathogens such as Cryptosporidium and tuberculosis reported in vulnerable communities, microsporidia have not been highlighted in the local HIV-positive population in Malaysia. This study aimed to provide preliminary information on the prevalence of microsporidia in the local HIV-population. Microsporidia were detected in 21/247 (8.5%) stool samples from the HIV-infected individuals, a significantly higher (P-value <0.05) prevalence than in the control group, in which 5/173 (2.9%) were positive. HIV patients were 3x more at risk for acquiring microspordium (OR: 3.12; 95% CI 1.15-8.44). Spores were ellipsoid in shape with outlines that stained dark pink with the interior a lighter shade. Approximately 21% of the positive specimens were from individuals in the 40-49 years age group. Ten individuals who were positive for microsporidia were also positive for other enteric parasites such as Blastocystis hominis and Giardia lamblia. We detected Encephalitozoon intestinalis DNA following nested PCR from three of 10 samples analysed, as demonstrated by an amplicon of 370bp. From the findings reported, it appears that microsporidial infection in humans may actually be more common than reported. We strongly advocate greater emphasis on personal hygiene through public education on personal hygiene and the consumption of boiled or filtered water. PMID:21596411

    Background The incidence of invasive cervical cancer in HIV-positive women is higher than in the general population. There is evidence that HIV-positive women do not participate sufficiently in cervical cancer screening in Italy, where cervical cancer is more than 10-fold higher in women with AIDS than in the general population. The aim of the present study was to evaluate the history of Pap-smear in HIV-positive women in Italy in recent years. We also examined the sociodemographic, clinical, and organizational factors associated with adherence to cervical cancer screening. Methods A cross-sectional study was conducted between July 2006 and June 2007 in Emilia-Romagna region (Northern Italy). All HIV-positive women who received a follow-up visit in one of the 10 regional infectivology units were invited to participate. History of Pap-smear, including abnormal smears and subsequent treatment, was investigated through a self-administered anonymous questionnaire. The association between lack of Pap-smear in the year preceding the interview and selected characteristics was assessed by means of odds ratios (OR) and 95% confidence intervals adjusted for study centre and age. Results A total of 1,002 HIV-positive women were interviewed. Nine percent reported no history of Pap-smear, and 39% had no Pap-smear in the year prior to the date of questionnaire (last year). The lack of Pap-smear in the last year was significantly associated with age <35 years (OR = 1.4, compared to age ≥45 years), lower education level (OR = 1.3), first HIV-positive test in the last 2 years (OR = 1.4), and CD4 count <200 cells/μl (OR = 1.6). Conversely, when women were advised by a gynecologist rather than other health workers to undergo screening, it significantly increased adherence. Non-significantly higher proportions of lack of Pap-smear in the last year were found in women born in Central-Eastern Europe (OR = 1.8) and Africa (OR = 1.3). No difference in history of Pap-smear emerged by

    Women in their reproductive years make up about 50% of all HIV-positive persons globally. These women, just as their HIV-negative counterparts, wield the right to procreate. However, HIV infection and lack of appropriate information on reproductive options may negatively impact women's procreative decision-making. This study assessed fertility intentions of HIV-positive women receiving antiretroviral therapy (ART) in southern Ghana. Quantitative methods were used to collect data from HIV-positive women receiving ART at four treatment centers. HIV-positive aged 18-49 years, and receiving ART were selected using systematic random sampling technique. Three hundred eighteen women were interviewed after informed consent. We used univariate analysis to generate descriptive tabulations for key variables. Bivariate analysis and logistic regression modeling respectively produced unadjusted and adjusted associations between background attributes of respondents and their childbearing decision-making. All analyses were performed using IBM SPSS Statistics for Windows, Version 20.0. Irrespective of age, reproductive history, and duration of HIV diagnosis, 46% of the women were desirous of procreating. The bivariate level analysis shows that women in their late reproductive ages (30-39 years) had the strongest desire to procreate (p < 0.001). After controlling for a number of covariates, primiparous and secundiparious women were about twice as likely to desire children (aOR = 2.553; 95% CI 1.480-4.401), and so were women aged 30-39 years (aOR = 2.149; 95% CI 1.202-3.843). Of 54% women who do not wish to procreate, achievement of desired family size (64.3%) was more popular a reason than fear of vertical transmission of HIV (7.5%), poor health status (5%), and pregnancy-related complications (1.6%).

    Background : Women have historically been under-represented in HIV research, partly due to ineffective recruitment strategies. Objective : To improve the existing understanding of recruitment for HIV-positive women based on a province-wide cross-sectional study. Methods : A survey was emailed to all site coordinators who recruited participants in a study involving 490 HIV-positive women living in Ontario, Canada. The survey consisted of questions regarding the important recruitment barriers and successes. Quantitative data were then contextualized within extensive knowledge from research personnel and team members. Results : Completed surveys were received from (89%) site coordinators (34/38) and 98% (31/34) were women. The highest ranked recruitment barriers identified were: sensitivity of the research topic (59%), time/availability constraints (59%), language barriers (53%), HIV disclosure/stigma issues (47%), lack of trust of research personnel (41%), fear of research (41%) and inaccessibility to child care and transportation (41%). The respondents felt that the most important personal attributes for recruitment were research personnel who were respectful (97%), skilled (91%), flexible (88%) and empathetic (88%) and had good communication skills (88%). The most successful recruitment strategies identified were: developing a strong rapport (88%) that was facilitated by an empathetic relationship (100%), acknowledging the sensitive nature of the research topic (94%), providing cash financial compensation (88%), and developing recruitment strategies unique to women (88%). Conclusion : There are differences in the approaches needed for the recruitment of HIV-positive women in research. For successful recruitment of HIV-positive women, a strong rapport between the research personnel and study participants is important. This rapport is facilitated by having study personnel who are respectful, trustworthy, empathetic, and flexible. Population-specific recruitment

    Background Lack of early initiation of antiretroviral therapy (ART) remains a major health concern due to increased risk of premature mortality and further HIV transmission. This study explored CD4+ cell count monitoring in relation to delays in ART initiation among HIV-positive individuals in the Kathmandu Valley, Nepal, where ART coverage was only 23.7% in 2011. Design We recruited a total of 87 ART-naïve, HIV-positive individuals aged 18 to 60 years through the networks of five non-government organizations working with HIV-positive individuals. We collected data on the history of ART initiation, CD4+ cell count monitoring, socio-demographic variables, perceived family support (measured with 10-item Nepali Family Support and Difficulty Scale), depression, and HIV symptom burden. Correlates of ART eligibility were examined using multivariable logistic regression analysis. Results A total of 72 of the 87 ART-naïve participants (82.8%) had monitored their CD4+ cell count in the past 6 months. Of these, 36 (50%) participants were eligible for ART initiation with CD4+ cell count <350 cells/mm3. A total of 12 participants had CD4+ cell count <200 cells/mm3. Lower level of perceived family support was associated with 6.05-fold higher odds (95% confidence interval =1.95 to 18.73) of being ART eligible with a CD4+ cell count <350 cells/mm3. Conclusions High rate of delays in ART initiation and the strong association of low perceived family support with ART eligibility in our study participants suggest that HIV service providers should consider the role and impact of family support in influencing individual decisions to initiate ART among eligible HIV-positive individuals.

    The human immunodeficiency virus (HIV) is known to cause altered disease presentations. We present here, the case of a 14-year-old boy who came to us with a chronic, painful, nonhealing ulcer of 4 months duration over the dorsum of right hand. Before our observation, he was variably diagnosed and treated as atypical mycobacterial infection, deep fungal infection, squamous cell carcinoma, and pyoderma gangrenosum. On administration of systemic corticosteroids his condition worsened, after which he was tested for, and found to be HIV positive. He was put onto valacyclovir, responded slowly, with healing after 2 months of antiviral therapy. The case report highlights unusual presentation in an under-considered age group and a slow response to otherwise effective therapy. PMID:26392660

    HIV-positive individuals have traditionally been barred from donating organs due to transmission concerns, but this barrier may soon be lifted in the USA in limited settings when recipients are also infected with HIV. Recipients of livers and kidneys with well-controlled HIV infection have been shown to have similar outcomes to those without HIV, erasing ethical concerns about poorly chosen beneficiaries of precious organs. But the question of whether HIV-negative patients should be disallowed from receiving an organ from an HIV-positive donor has not been adequately explored. In this essay, we will discuss the background to this scenario and the ethical implications of its adoption from the perspectives of autonomy, beneficence/non-maleficence and justice. PMID:24899522

    Purpose The purpose of this study was to assess the disclosure of HIV-positive status and its associated factors to sexual partners among patients attending antiretroviral therapy (ART) clinic follow-up at Mekelle Hospital, Tigray, Ethiopia. Patients and methods An institution-based cross-sectional study was conducted at Mekelle hospital. Samples of 324 individuals were selected by using systematic random sampling techniques from July 1 until July 30, 2013. The data were collected by trained data collectors through a pretested semi-structured questionnaire. The collected data were cleaned, coded, entered, and analyzed using SPSS version 16.0 Windows program. Descriptive statistics and binary and multivariable regression analysis with 95% confidence interval was carried out and P-value less than 0.05 used to determine the significant association. Results A total of 324 people on ART care follow-up were interviewed with 100% response rate. The overall HIV status disclosure to sexual partner was 57.4%. Among those who disclosed their HIV status, 58% of them told their partner after 1 month after diagnosis. The study showed that there is significant association between knowing HIV status of sexual partner (adjusted odds ratio [AOR] =16.69, 95% CI: 5.4, 51.65), duration of HIV-related care follow-up (AOR =5.48, 95% CI =2.17, 13.80), and discussion before HIV testing (AOR =4.33, 95% CI =1.43, 13.08), with HIV-positive status disclosure to sexual partner. Conclusion An HIV-positive status disclosure to a sexual partner in this study was lower than what was reported in other studies in Ethiopia. The duration of HIV-related care follow-up, knowing partner’s HIV status, and prior discussion were the main factors that affected the practice of HIV-positive status disclosure to their sexual partners.

    This study aimed to assess the prevalence of depressed symptoms and associated factors in prenatal HIV-positive women in primary care facilities in rural South Africa. In a cross-sectional study, 663 HIV-positive prenatal women in 12 community health centres in Mpumalanga province, South Africa, were recruited by systematic sampling (every consecutive patient after HIV post-test counselling). Results indicate that overall, 48.7% [95% CI: 44.8, 52.6] of women during the prenatal period reported depressed mood (scores of ≥ 13 on the Edinburgh Postnatal Depression Scale 10). In multivariate analysis, not being employed, unplanned pregnancy, not having an HIV-positive child, poor antiretroviral therapy adherence, non-condom use at last sex, and intimate partner violence were associated with depressive symptoms. Potential risk factors among HIV-infected prenatal women were identified which could be utilized in interventions. Routine screening for depression may be integrated into prenatal care settings.

    We compared macronutrient intake, food insecurity, and anthropometrics in breastfeeding women: 40 HIV-positive women not yet on antiretroviral therapy and 40 HIV-negative women. Calculated deficits at 2 weeks were 517 kcal per day for HIV-positive women vs 87 kcal per day surplus for HIV-negative women (P = 0.01) and 29 g protein per day for HIV-positive women vs 16 g protein per day for HIV-negative women (P = 0.04). Food insecurity scores were 11.3 for HIV-positive women vs 7.8 for HIV-negative women (P < 0.01). Enhanced dietary education together with macronutrient supplementation may be required to improve health outcomes in HIV-positive women and their infants. PMID:25230293

    Prevalence of subclinical hypothyroidism in HIV-positive patients is reported to be high in those with severe immune deficiency. However, there is paucity of literature in newly-diagnosed HIV-positive population. Our aim was to estimate the prevalence of thyroid dysfunction and study its correlation with CD4 count in this population. In this cross-sectional study, patients presenting to the antiretroviral therapy clinic were screened with thyroid function tests, including thyroid stimulating hormone, free triiodothyronine, free thyroxine, and anti-thyroid peroxidase antibody levels at the time of diagnosis. Two hundred and twenty-five HIV-positive and an equal number of healthy volunteers were enrolled. The mean (SD) CD4 count in the study group was 147.1 (84) and 70.7% had advanced immune deficiency with CD4 count <200 cells/µL. The overall prevalence of thyroid dysfunction was 75.5% in the study group and 16% in the control group. Subclinical hypothyroidism was the commonest abnormality noted in almost 53%. Significant correlation was observed between CD4 count and thyroid stimulating hormone, free triiodothyronine, and free thyroxine levels (r = -0.86, r = 0.77, and r = 0.84, respectively, p < 0.0001 for all). The present study demonstrated high prevalence of thyroid dysfunction in HIV-positive patients. The dysfunction is subclinical in most cases and correlates well with declining CD4 counts.

    Forty people over 60 years of age took part in longitudinal research over the course of a year on the impact of the HIV epidemic in southern Uganda. In this paper we focus mainly on the data from 26 of the 40 who were HIV-positive. While we observed that feelings of depression were frequently experienced by many of the people in our study, the state of 'being depressed' was not constant. Participants regularly expressed economic frustration (because of a lack of money to buy food and other commodities including sugar and soap); medical problems (including those related to HIV) as well as old age, the burden of dependents (including concerns about school fees for grandchildren), feelings of sadness and isolation, and a lack of support from others, as well as stigma, whether real or perceived. However, while worries, sorrow and despondent thoughts were reported in many of the interviews across the study, moods fluctuated moving from happiness and hope, to sadness and despair, from month to month. Concerns regarding the psychological wellbeing amongst older people, including those living with HIV and older carers in Uganda deserve greater attention. PMID:22930234

    The aim of this study was to investigate the prevalence and factors associated with suicidal ideation among HIV-positive men who have sex with men (MSM) in Anhui, China. A cross-sectional study was conducted to recruit HIV-positive MSM in Anhui, China. A total of 184 HIV-positive MSM gave informed consent and completed the interview. Correlates of suicidal ideation were assessed using multivariable logistic regression. Fifty-seven (31%) of HIV-positive MSM had suicidal ideations within six months before the interview. Multivariable analyses showed that learning of their HIV status in the past 12 months (adjusted odds ratio (AOR) = 3.4, 95% CI = 1.6-7.3), perceived HIV stigma (AOR = 2.4, 95% CI = 1.1-5.2), depression symptoms (AOR = 2.6, 95% CI = 1.1-5.9) and anxiety symptoms (AOR = 2.7, 95% CI = 1.2-6.1) were significantly associated with the suicidal ideation among HIV-positive MSM. The results indicated that suicidal ideation was common among HIV-positive MSM in Anhui, China. There is an urgent need to establish psychological counselling services among HIV-positive MSM in China. Targeting of these potential risk factors could be an effective approach to reduce the suicide risk among this high-risk subgroup by the implementation of early intervention measurements.

    A prospective, comparative study of the prevalence of enteric protozoa was determined among human immunodeficiency virus (HIV)- positive and HIV-negative men who have sex with men (MSM) in Sydney, Australia. A total of 1,868 patients submitted stool specimens; 1,246 were from MSM (628 HIV positive and 618 HIV positive) and 622 from non-MSM were examined over a 36-month period. A total of 651 (52.2%) stool specimens from MSM were positive for protozoa compared with 85 (13%) from non-MSM. There was a significant difference in the prevalence of Blastocystis hominis, Endolimax nana, Entamoeba histolytica/dispar complex, Entamoeba hartmanni, Iodamoeba butschlii, and Enteromonas hominis detected between MSM and non-MSM (P<0.001). The only notable difference between HIV-negative and HIV-positive MSM was that HIV-infected MSM were found to more likely have a Cryptosporidium parvum infection. Entamoeba histolytica was found in 3 patients, E. dispar in 25, and E. moshkovskii in 17, all of whom were MSM. When compared with a control group, MSM were significantly more likely to harbor intestinal protozoa and have multiple parasites present. The results of this study show high rates of enteric parasites persist in MSM and highlight the importance of testing for intestinal parasites in MSM. This is the first report of E. moshkovskii from MSM. PMID:17360882

    Background: To determine the prevalence of neurocognitive impairment (NCI) in UK HIV-positive and HIV-negative men who have sex with men (MSM). Methods: HIV-positive and HIV-negative participants were recruited to a cross-sectional study from 2 London clinics and completed computer-assisted neuropsychological tests and questionnaires of depression, anxiety, and activities of daily living. Published definitions of HIV-associated neurocognitive disorders (HAND) and global deficit scores were used. Age- and education-adjusted neuropsychological test scores were directly compared with reference population data. Results: A total of 248 HIV-positive and 45 HIV-negative MSM participated. In the HIV-positive group, median time since diagnosis was 9.4 years, median CD4+ count was 550 cells per cubic millimeter, and 88% were on antiretroviral therapy. Prevalence of HAND was 21.0% in HIV-positive MSM (13.7% asymptomatic neurocognitive impairment, 6.5% mild neurocognitive disorder, and 0.8% HIV-associated dementia). Using a global deficit score threshold of 0.5, the prevalence of NCI was 31.5% (when averaged over 5 neuropsychological domains) and 40.3% (over 10 neuropsychological test scores). These results were not significantly different from the HIV-negative study sample. No consistent pattern of impairment was seen in HIV-positive patients relative to general male population data (n = 380). Conclusions: We found a prevalence of HAND and degree of impairment on neuropsychological testing of HIV-positive MSM that could represent a normal population distribution. These findings suggest that NCI may be overestimated in HIV-positive MSM, and that the attribution of NCI to HIV infection implied by the term HAND requires revision. PMID:24991974

  20. Breastfeeding in HIV-positive women: What can be recommended?

    2010-01-01

    Breastfeeding remains a common practice in parts of the world where the burden of HIV is highest and the fewest alternative feeding options exist. The impossible dilemma faced by HIV-positive mothers is whether to breastfeed their infants in keeping with cultural norms but in doing so risk transmitting the virus through breast milk, or to pursue formula feeding, which comes with its own set of risks, including a higher rate of infant mortality from diarrheal illnesses, while reducing transmission of HIV. Treatment of mothers and/or their infants with antiretroviral drugs is a strategy that has been employed for several decades to reduce HIV transmission through pregnancy and delivery, but the effect of these agents when taken during breastfeeding is a newer field of study. In this article we evaluate the latest clinical research, from trials that encourage exclusive breastfeeding to trials of antiretroviral therapy (ART) for either the mother or infant, in an attempt to prevent transmission of HIV through breast milk. Additionally, we discuss research that is in progress, with results anticipated in the next few years that will further shape clinical guidelines and practice. Exclusive breastfeeding is much safer than mixed feeding (the supplementation of breastfeeding with other foods), and should be encouraged even in settings where ART for either the mother or infant is not readily available. The research published regarding maternal treatment with highly active antiretroviral therapy (HAART) during pregnancy and the breastfeeding period has all been non-randomized with relatively little statistical power, but suggests maternal HAART can drastically reduce the risk of transmission of HIV. Infant prophylaxis has been intensively studied in several trials and has been shown to be as effective as maternal treatment with antiretrovirals, reducing the transmission rate after 6 weeks to as low as 1.2%. Research that is in progress will provide us with more answers

    The goal of this study was to evaluate skeletal, dental and chronological development in an HIV-positive group of children, as compared with a control group, during a four-year period. Panoramic radiographs and hand and wrist radiographs of 60 children were taken. The children, of both sexes, aged 5 years and 2 months to 15 years and 5 months, were selected as follows: 30 HIV-positive volunteers who had acquired the disease vertically, and 30 volunteers who did not present the HIV infection or any other systemic disease. All radiographs were technically standardized and analyzed according to criteria established by Nolla (dental age), Greulich and Pyle (bone age), and Eklöf and Ringertz (bone age). The results were submitted to Student's t-test at a 5% level of significance. Based on the comparison between the chronological age and the dental or the skeletal age, significant differences were observed between HIV-positive and HIV-negative children, both in 1999 and in 2003 (p < or = 0.05). Considering the results obtained with the methodology used, it was concluded that HIV-positive children of both sexes presented delayed bone development despite the administration of antiretroviral drugs, and that HIV-positive female children presented younger dental ages compared with their chronological ages in 1999 and in 2003; and HIV-positive males, in 1999.

    Although stigma towards HIV-positive women for both continuing and terminating a pregnancy has been documented, to date few studies have examined relative stigma towards one outcome versus the other. This study seeks to describe community attitudes towards each of two possible elective outcomes of an HIV-positive woman's pregnancy - induced abortion or birth - to determine which garners more stigma and document characteristics of community members associated with stigmatising attitudes towards each outcome. Data come from community-based interviews with reproductive-aged men and women, 2401 in Zambia and 2452 in Nigeria. Bivariate and multivariate analyses revealed that respondents from both countries overwhelmingly favoured continued childbearing for HIV-positive pregnant women, but support for induced abortion was slightly higher in scenarios in which anti-retroviral therapy (ART) was unavailable. Zambian respondents held more stigmatising attitudes towards abortion for HIV-positive women than did Nigerian respondents. Women held more stigmatising attitudes towards abortion for HIV-positive women than men, particularly in Zambia. From a sexual and reproductive health and rights perspective, efforts to assist HIV-positive women in preventing unintended pregnancy and to support them in their pregnancy decisions when they do become pregnant should be encouraged in order to combat the social stigma documented in this paper.

    Background. Preventing unintended pregnancy in HIV-positive women can significantly reduce maternal-to-child HIV transmission as well as improve the woman's overall health. Hormonal contraceptives are safe and effective means to avoid unintended pregnancy, but there is concern that coadministration of antiretroviral drugs may alter contraceptive efficacy. Materials and Methods. We performed a literature search of PubMed and Ovid databases of articles published between January 1980 and February 2012 to identify English-language reports of drug-drug interactions between hormonal contraceptives (HCs) and antiretroviral drugs (ARVs). We also reviewed the FDA prescribing information of contraceptive hormone preparations and antiretrovirals for additional data and recommendations. Results. Twenty peer-reviewed publications and 42 pharmaceutical package labels were reviewed. Several studies of combined oral contraceptive pills (COCs) identified decreased serum estrogen and progestin levels when coadministered with certain ARVs. The contraceptive efficacy of injectable depot medroxyprogesterone acetate (DMPA) and the levonorgestrel intrauterine system (LNG-IUS) were largely unaffected by ARVs, while data on the contraceptive patch, ring, and implant were lacking. Conclusions. HIV-positive women should be offered a full range of hormonal contraceptive options, with conscientious counseling about possible reduced efficacy of COCs and the contraceptive implant when taken with ARVs. DMPA and the LNG-IUS maintain their contraceptive efficacy when taken with ARVs. PMID:22927715

    In China, specific HIV/AIDS-related services have been in place since 2004. However, utilisation of these services remains limited among people living with HIV. We explored barriers to accessing HIV/AIDS-related services from the perspective of newly diagnosed HIV-positive men who have sex with men. We conducted repeated in-depth interviews with 31 newly diagnosed HIV-positive men who have sex with men, using the socio-ecological framework and thematic content analysis. Multiple barriers for utilisation of HIV/AIDS-related services were identified, including perceptions of subjective health and poor quality of services, mental and emotional health problems, lack of trust and understanding of the services on offer, low economic status, lack of insurance, and high medical fees, being refused access to services, and restrictive attendance policies. The findings provide information on potential multi-level obstacles preventing newly diagnosed HIV-positive men who have sex with men to use services that they need. It is recommended that policy makers should create a trustful and non-discriminating environment and services integrating physical and mental healthcare. PMID:24626063

    Background Patients’ experiences are a reflection of what has happened during the care process and, therefore, provide information about the performance of health care professional workers. They refer to the process of care provision at the antiretroviral therapy (ART) sites. Aim and setting This article explored the perceptions of HIV-positive patients of care received at the Gateway Clinic of the regional hospital that provides antiretroviral treatment in the Vhembe district. Methods A qualitative, explorative and descriptive design was used. A non-probability, convenient sampling method was used to select 20 HIV-positive patients who were above 18 years of age. In-depth individual interviews were used to collect data. Data were analysed through Tech’s open coding method. Results One theme and two sub-themes emerged, namely positive experiences related to the environment and attitudes of health professionals, and negative experiences concerning the practices by health care providers. Conclusion Patients’ perceptions of quality of, and satisfaction with, health care may affect health outcomes. Recommendations are made to consider, practice and strengthen the protocols, the standard operating procedures and the principles of infection control in the health facilities. PMID:27380841

    Introduction Recent international guidelines call for expanded access to triple-drug antiretroviral therapy (ART) in HIV-positive women during pregnancy and postpartum. However, high levels of non-adherence and/or disengagement from care may attenuate the benefits of ART for HIV transmission and maternal health. We examined the frequency and predictors of disengagement from care among women initiating ART during pregnancy in Cape Town, South Africa. Methods We used routine medical records to follow-up pregnant women initiating ART within prevention of mother-to-child transmission of HIV services in Cape Town, South Africa. Outcomes assessed through six months postpartum were (1) disengagement (no attendance within 56 days of a scheduled visit) and (2) missed visits (returning to care 14–56 days late for a scheduled visit). Results A total of 358 women (median age, 28 years; median gestational age, 26 weeks) initiated ART during pregnancy. By six months postpartum, 24% of women (n=86) had missed at least one visit and an additional 32% (n=115) had disengaged from care; together, 49% of women had either missed a visit or had disengaged by six months postpartum. Disengagement was more than twice as frequent postpartum compared to in the antenatal period (6.2 vs. 2.4 per 100 woman-months, respectively; p<0.0001). In a proportional hazards model, later gestational age at initiation (HR: 1.04; 95% CI: 1.00–1.07; p=0.030) and being newly diagnosed with HIV (HR: 1.57; 95% CI: 1.07–2.33; p=0.022) were significant predictors of disengagement after adjusting for patient age, starting CD4 cell count and site of ART initiation. Conclusions These results demonstrate that missed visits and disengagement from care occur frequently, particularly post-delivery, among HIV-positive women initiating ART during pregnancy. Women who are newly diagnosed with HIV may be particularly vulnerable and there is an urgent need for interventions both to promote retention overall, as well as

    This was a single-center, open-label study of lopinavir/ritonavir (LPV/r) single-agent therapy in antiretroviral-naive, HIV-infected participants initiating therapy with twice-daily soft-gelatin capsules (SGC) and switched to tablets after ≥4 weeks. The objective was to evaluate quality of life and tolerability of the 2 formulations. Participants quality of life, depression, and tolerability were measured using the Medical Outcomes Study-HIV (MOS-HIV), Modified Global Condition Improvement (GCI), and Center for Epidemiologic Studies-Depression (CES-D), prior to and 4 weeks following switch. MOS-HIV showed significant improvements in general health perception (+6 (16), mean (SD); P = .047) and role functioning (+8 (19), mean (SD); P = .023) post-switch. GCI showed significant improvement in ease of taking medications with tablets (56.7% vs 83.3%; P = .021). No change was observed in CES-D. Tolerability improved in 47%. Reported diarrhea (grade 2) was higher during SGC (33.3% vs3.3%; P = .004). Quality-of-life measures, tolerability, and diarrhea improved with the LPV/r tablet formulation compared to SGC in HIV-positive patients not receiving other antiretroviral therapy (ART).

    were selected for the studies, details of the test and reference standards (the benchmark test), and study flow and timing, using the standard QUADAS-2 approach. Few studies used multiple types of specimens for the reference standard (higher quality standard) and most relied on sputum culture alone (lower quality standard), which may have affected results. What do the results mean? In a population of 1000 HIV-positive individuals with TB symptoms, where 300 actually have TB, the test will correctly identify 135 people as having TB, but miss the remaining 165 people; for the 700 people who do not have TB, the test will correctly identify 644 people as not having TB, but will misclassify 56 as having TB. The sensitivity of the test is higher in people living with HIV with low CD4 cell counts who are at risk of life-threatening illnesses. In patients with a CD4 ≤ 100 cells per µL, LF-LAM sensitivity was 56% (41% to 70%) versus 26% (16% to 46%) in patients with a CD4 count = 100 cells per µL. If the test is used in screening HIV-positive people for TB, in a population of 1000 where 10 actually have TB, LF-LAM will correctly identify none of the 10, or up to four of the 10; on the other hand, the test will miss six to 10 people with TB; in the remaining 990 who do not have TB, the test will correctly identify 931 to 941 people as not having TB while misclassifying 49 to 59 as having TB. Limitations The main limitations of the review were the use of a lower quality reference standard in most included studies, and small number of studies and participants included in the analyses. The results should, therefore, be interpreted with caution. Conclusions In this Cochrane review, we found that LF-LAM, whether the test is used for diagnosis or screening, has low sensitivity to detect TB. However, in HIV-positive people with low CD4 counts who are seriously ill, LF-LAM may help with the diagnosis of TB. PMID:27163343

    Background The risk of sexual HIV transmission in serodiscordant couples when the HIV-positive partner has full virologic suppression on combination antiretroviral therapy (cART) is debated. This study aims to systematically review observational studies and randomized controlled trials (RCTs), evaluating rates of sexual HIV transmission between heterosexual serodiscordant couples when the HIV-positive partner has full suppression on cART. Methods and Findings We searched major bibliographic databases to November 2012 for relevant observational studies and RCTs without language restrictions. Conference proceedings, key journals and bibliographies were also searched. Studies reporting HIV transmission rates, cART histories and viral loads of the HIV-positive partners were included. Two reviewers extracted methodologic characteristics and outcomes. Of 20,252 citations, 3 studies met all eligibility criteria with confirmed full virologic suppression in the HIV-positive partner. We included 3 additional studies (2 cohort studies, 1 RCT) that did not confirm viral suppression in the HIV-positive partner at transmission in a secondary meta-analysis. Methodologic quality was reasonable. The rate of transmission in the 3 studies confirming virologic suppression was 0 per 100 person-years (95% CI = 0–0.05), with low heterogeneity (I2 = 0%). When we included the 3 studies that did not confirm virologic suppression, the rate of transmission was 0.14 per 100 person-years (95%CI = 0.04–0.31) (I2 = 0%). In a sensitivity analysis including all 6 studies, the rate of transmission was 0 per 100 person-years (95%CI = 0–0.01) after omitting all transmissions with known detectable or unconfirmed viral loads, as full suppression in these cases was unlikely. Limitations included lack of data on same-sex couples, type of sexual intercourse (vaginal vs. anal), direction of HIV transmission, exact viral load at the time of transmission, sexually transmitted

    The amyloid beta (Aβ) oligomers and fibrils that are found in neural tissues of patients suffering from Alzheimer's disease may either cause or contribute to the pathology of the disease. In vitro, these Aβ-aggregates are characterized by structural polymorphism. However, recent solid state NMR data of fibrils acquired post mortem from the brains of two Alzheimer's patients indicate presence of only a single, patient-specific structure. Using enhanced molecular dynamic simulations we investigate the factors that modulate the stability of Aβ-fibrils. We find characteristic differences in molecular flexibility, dynamics of interactions, and structural behavior between the brain-derived Aβ-fibril structure and in vitro models. These differences may help to explain the lack of polymorphism in fibrils collected from patient brains, and have to be taken into account when designing aggregation inhibitors and imaging agents for Alzheimer's disease.
