The course of human immunodeficiency virus infection and the acquired immunodeficiency syndrome can be complicated by a variety of endocrine abnormalities, including abnormalities of thyroid gland. This study was designed to understand the spectrum of pathology of thyroid in Indian patients with AIDS. The present study describes the findings of retrospective autopsy findings of 158 patients with AIDS which revealed infectious diseases from a time period before the use of highly active antiretroviral regimen. A wide range of bacterial, fungal, and viral infections were observed. Tuberculosis was recorded in 14 (09%) patients, Cryptococcus neoformans in 11 (7%) patients and cytomegalovirus in 3 (2%) patients. Hashimoto's thyroiditis and lymphocytic thyroiditis were seen in 02 (01%) patients each. One patient had dual infection comprising of tuberculosis and cytomegalovirus infection. The other microscopic findings observed were goiter (2 patients), interstitial fibrosis in thyroid (7 patients), and calcification in thyroid (8 patients). Abnormalities of thyroid are uncommon findings in patients with HIV infection however several case reports of thyroid involvement by infectious agents and neoplasm are described in these patients; hence patients with HIV infection should be closely followed up for development of goiter or abnormalities of thyroid functions.

To assess the utility of the National Death Index (NDI) in improving the ascertainment of deaths among people diagnosed with acquired immunodeficiency syndrome (AIDS), the authors determined the number and characteristics of additional deaths identified through NDI linkage not ascertained by using standard electronic linkage with Florida Vital Records and the Social Security Administration's Death Master File. Records of people diagnosed with acquired immunodeficiency syndrome between 1993 and 2007 in Florida were linked to the NDI. The demographic characteristics and reported human immunodeficiency virus (HIV) transmission modes of people whose deaths were identified by using the NDI were compared with those whose deaths were ascertained by standard linkage methods. Of the 15,094 submitted records, 719 had confirmed matches, comprising 2.1% of known deaths (n = 34,504) within the cohort. Hispanics, males, people 40 years of age or older, and injection drug users were overrepresented among deaths ascertained only by the NDI. In-state deaths comprised 59.0% of newly identified deaths, and human immunodeficiency virus was less likely to be a cause of death among newly identified compared with previously identified deaths. The newly identified deaths were not previously ascertained principally because of slight differences in personal identifying information and could have been identified through improved linkages with Florida Vital Records.

We report a case of a patient with acquired immunodeficiency syndrome (AIDS) and ileocecal ulcer. A 31-year-old man was admitted with chief complaints of decreased body weight and abdominal pain. Colonoscopy revealed a round punched-out ulcer on the ileocecal valve. Initially, we suspected entero-Behçet's disease and simple ulcer as the cause of the ileocecal ulcer. However, after histologic examination of tissue biopsies obtained during colonoscopy, we diagnosed the patient as having cytomegalovirus (CMV) enteritis. Based on the patient's white blood cell depletion and CMV enteritis, we performed a human immunodeficiency virus (HIV) antibody test. The test was positive, and the diagnosis of AIDS was established. The number of patients with AIDS has been increasing in Japan; thus, we should consider the possibility of CMV enteritis and AIDS in young adult patients affected by ileocecal ulcer with no notable history.

Abstract Cytomegalovirus (CMV) infection in immunocompromised patients is a common opportunistic systemic infection which can lead to death, and usually presents with visceral manifestations, especially of the lung, brain, eye, and gastrointestinal tract. Cutaneous CMV infection is, however, relatively rare in immunocompromised patients. Cutaneous CMV infection can have variable clinical and histologic manifestations, and thus can be easily missed. We report a case of cutaneous CMV infection in a patient with acquired immunodeficiency syndrome, presenting as a generalized, pruritic, erythematous, maculopapular eruption.

In endemic regions, visceral leishmaniasis is one of the most common opportunistic infections in HIV positive patients. Simultaneous infection with Leishmania and HIV has been reported in some countries but this is the first report of such a case in Iran. Our patient was a 27 years old man with intermittent night fever, abdominal pain, loss of appetite, vomiting, watery diarrhea and severe weight loss for 6 months. He had low socio-economic status with an imprisonment history. The patient was quite cachectic and had low grade fever. Physical exam and upper GI endoscopy revealed oropharyngeal candidiasis. Microscopic evaluation of duodenal biopsy material showed Leishmania amastigotes in macrophages of lamina propria. Leishman bodies were also observed in bone marrow aspiration specimen. Serologic tests were positive for Leishmania infantum. HIV antibody was also positive with a CD4+cell count of 80/μl. The diagnosis was acquired immunodeficiency syndrome with simultaneous visceral leishmaniasis involving intestinal mucosa.

Polymorphous hemangioendotheliomas (PH) are rare and borderline malignant tumors that are among the wide range of vascular tumors. We report here a 13-year-old male presenting with a history of weight loss, opportunistic infections, and lymphadenopathy. He was determined to be HIV positive and to have acquired immunodeficiency syndrome (AIDS). A biopsy of a femoral node was diagnostic of PH. His systemic lymphadenopathy appeared to resolve with anti-retroviral therapy. This tumor should be considered within the differential diagnoses of pediatric and immunocompromised patients.

Here, I report the case of a 31-year-old immigrant Burmese woman who exhibited epigastralgia, fever, weight loss and an epigastric mass. The patient was diagnosed with pancreatic TB and acquired immunodeficiency syndrome, and was treated with antituberculous drugs and percutaneous catheter drainage without a laparotomy. The clinical presentation, radiographic investigation and management of pancreatic TB are summarized in this paper to emphasize the importance of considering this rare disease in the differential diagnosis of pancreatic masses concomitant with human immunodeficiency virus infection. I also emphasize the need for both histopathological and microbiological diagnosis via fine-needle aspiration.

In this article, Medicaid enrollment, use, and expenditures for persons with acquired immunodeficiency syndrome in California from 1981-84 are examined. The data are from Tape-to-Tape, a person-level Medicaid enrollment and claims data base. It was found that expenditures per month of enrollment decreased as length of enrollment during the year increased. Average annual expenditures increased from 1982 to 1983 and then decreased in 1984. This decrease was most pronounced in hospital services with no indication of a substitution of ambulatory services. This decline is primarily a result of a decrease in hospital reimbursement per day as opposed to changes in use, because discharge rates decreased and length of stay increased. PMID:10312824

Update on non-acquired immunodeficiency syndrome-defining malignancies.

PubMed

Chiao, Elizabeth Y; Krown, Susan E

2003-09-01

Since the introduction of highly active antiretroviral therapy (HAART), the natural history of human immunodeficiency virus (HIV) infection has changed. Early in the acquired immunodeficiency syndrome (AIDS) epidemic, epidemiologic studies showed that HIV-infected patients were at higher risk for developing specific AIDS-defining malignancies. More recent studies linking HIV/AIDS databases to cancer registries have shown that HIV-infected patients are also at higher risk of developing non-AIDS-defining malignancies. We review the most recent data regarding clinical presentation, pathology, and treatment outcomes for these non-AIDS-defining malignancies. Recent large cohort studies linking HIV/AIDS databases to cancer registries have shown that HIV-infected patients are also at higher risk of developing non-AIDS-defining malignancies. Besides anal cancer and Hodgkin disease, the cohort studies have identified other malignancies that appear to occur at a higher rate in the HIV-infected population as compared with the general population. These malignancies include lung cancer, skin cancer, germ cell tumors, leiomyosarcomas, cancers of the head and neck, conjunctival cancer, multiple myeloma, and leukemias. As the epidemiology of non-AIDS-defining malignancies continues to evolve, it is unclear whether the appropriate treatments and outcomes for these or other malignancies are changed for HIV-infected patients treated with HAART.

To investigate the efficacy of highly active antiretroviral therapy (HAART) for acquired immunodeficiency syndrome (AIDS) in children. The clinical data of 38 children (2-15 years old) with AIDS from a region of Rwanda and who had received HAART were retrospectively reviewed. All of 13 children with anemia showed improved anemia symptoms after HAART. The hemoglobin contents returned to normal levels in 12 children with mild or moderate anemia. CD4 T lymphocytes increased by 24%-1 181% in 5 out of 6 cases with severe immunodeficiency after HAART. During the HAART, the weight gain averaged 2.3 kg yearly. The growth and development in 5 out of 8 children with delayed growth restored the levels of normal children of the same age after HAART. HAART can improve the health status in children with AIDS and is effective for childhood AIDS.

Strategies for confronting the epidemic of human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) have included a range of different approaches that focus on prevention and treatment. However, debate persists over what levels of emphasis are appropriate for the different components of the global response. This paper presents an overview of this debate and briefly summarizes the evidence on a range of interventions designed to prevent the spread of HIV infection, paying particular attention to voluntary counselling and testing, treatment for sexually transmitted infections and prevention of mother-to-child transmission. We also review the experience with antiretroviral therapy to date in terms of response rates and survival rates, adherence, drug resistance, behavioural change and epidemiological impact. Although various studies have identified strategies with proven effectiveness in reducing the risks of HIV infection and AIDS mortality, considerable uncertainties remain. Successful integration of treatment and prevention of HIV/AIDS will require a balanced approach and rigorous monitoring of the impact of programmes in terms of both individual and population outcomes.

In Spain, approximately 10 years passed between the time when human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) harm-reduction programs should have been developed with sufficient coverage to have an optimum impact on public health (before the HIV/AIDS epidemic's explosion in 1984) and the date of their actual implementation. This delay yielded an enormous cost for the country. The introduction of the virus in drug injector networks during a period of widespread diffusion of heroin injection and the lack of political awareness of the growing problem were 2 important factors that contributed to the important diffusion of the HIV infection among Spanish injection drug users. Lessons can be learned that may be of great interest in countries or territories facing similar challenges now and in the future.

1985-04-01

Blood and a variety of tissues from 97 patients with the acquired immunodeficiency syndrome (AIDS) and 25 with the AIDS prodrome were studied ultrastructurally. Tubuloreticular structures (TRS) were found in 85 per cent of the patients with AIDS and in 92 per cent of those with the prodrome. Test tube and ring-shaped forms (TRF), found in 41 per cent of the patients with AIDS and in 8 per cent of those with the prodrome, increased with disease progression. Among the patients with AIDS, as the number of sites examined per case increased, the incidence of TRS and TRF tended to approach 100 per cent, suggesting that they are present in all patients with AIDS. Other changes seen frequently were immunologic capping of blood lymphocytes, intramitochondrial iron in blood reticulocytes and marrow normoblasts, megakaryocytic immaturity and platelet phagocytosis, collections of membranous rings in hepatocytic cytoplasm, suggestive of non-A, non-B hepatitis, and proliferations and engorgement of hepatic Ito cells with lipid. The data suggest that TRS and TRF can be used as diagnostic and prognostic markers.

We examined the peripheral auditory system and the auditory brainstem pathway of children with Acquired Immunodeficiency Syndrome (AIDS). One hundred and one children, 51 with AIDS diagnosis and 50 normal children were evaluated. Audiological assessment included immittance measures, pure tone and speech audiometry and auditory brainstem response (ABR). The children with AIDS more frequently had abnormal results than did their matched controls, presenting either peripheral or auditory brainstem impairment. We suggest that AIDS be considered a risk factor for peripheral and/or auditory brainstem disorders. Further research should be carried out to investigate the auditory effects of HIV infection along the auditory pathway.

Acquired immunodeficiency syndrome (AIDS), an increasingly significant health problem, presents a special challenge to Medicaid programs. Analyzed in this article is one particular approach to providing services for Medicaid-eligible AIDS patients: the Medicaid home and community-based (section 2176) waiver program, authorized by the 1981 Omnibus Budget Reconciliation Act and amended in 1985 to include persons with AIDS. The authors conclude that the AIDS-specific waiver is an attractive program for the States, but that changes in program administration and in how cost effectiveness is determined would likely facilitate broader acceptance by the States.

In this study, the authors examine the longitudinal experience, annual trends, and subpopulation differences in Medicaid use and expenditures for persons with acquired immunodeficiency syndrome (AIDS) in California from 1983 through 1986. About two-thirds of adult males were enrolled in Medicaid within 1 month of their AIDS diagnosis. These recipients averaged approximately 20-percent higher lifetime expenditures than those enrolled at a later time. Monthly expenditures were higher in the beginning of enrollment and prior to death than in the months in between. From 1983 through 1986, there was a shift of care from inpatient to outpatient settings. In 1986, children and adult females had higher median expenditures than did adult males. PMID:10122357

In patients with acquired immunodeficiency syndrome (AIDS), disturbances in the circulation of retinal vessels are mostly encountered at the microvascular level. Rarely observed large retinal vessel occlusions frequently affect retinal veins. A 32-year-old woman was admitted to the authors' clinic with sudden loss of vision. Her clinical and ophthalmologic examinations and laboratory tests were carried out and the results were evaluated. The patient's history revealed a diagnosis of AIDS established 5 years ago. Her corrected visual acuity was limited to light perception in the right eye and 20/60 in the left eye. There was afferent pupillary defect in the right eye. Posterior segment examination demonstrated central retinal artery occlusion in the right eye and cotton-wool spots in the left eye. The clinical examination and laboratory test results did not reveal any comorbid disease state that can contribute to this presentation. As thrombi may develop in patients with human immunodeficiency virus infection, they should be closely followed up for the development of vasoocclusive disease.

We treated a patient with intracranial malignant lymphoma associated with acquired immunodeficiency syndrome(AIDS)caused by HIV infection. The recommendations of the countermeasure manual for AIDS were followed. Only surgical staff without finger injury or inflammation were permitted to be involved in the operation. All staff were dressed in a waterproof, full-body surgical gown, and wore double gloves, double foot covers, and an N95 mask. The surgery could be performed safely with such infection control measures. Histological examination revealed a diffuse large B-cell lymphoma. The patient was referred to the Division of Infectious Diseases and Respiratory Medicine for chemotherapy.

Acquired immunodeficiency syndrome (AIDS), caused by human immunodeficiency virus (HIV), has become, because of the rapid spread of the disease, a serious global problem and cannot be treated. Recent studies indicate that VIF is a protein of HIV to prevent all of human immunity to attack HIV. Molecular compounds of traditional Chinese medicine (TCM) database filtered through molecular docking and molecular dynamics simulations to inhibit VIF can protect against HIV. Glutamic acid, plantagoguanidinic acid, and Aurantiamide acetate based docking score higher with other TCM compounds selected. Molecular dynamics are useful for analysis and detection ligand interactions. According to the docking position, hydrophobic interactions, hydrogen bonding changes, and structure variation, the study try to select the efficacy of traditional Chinese medicine compound Aurantiamide acetate is better than the other for protein-ligand interactions to maintain the protein composition, based on changes in the structure.

Qualitative, descriptive, exploratory research conducted at a Voluntary Counseling and Testing Center with 10 elderly people receiving treatment for HIV/AIDS. The data were analyzed according to the content analysis. Data show the elderly people's lack of knowledge about HIV/AIDS transmission, the experience of being elderly and having HIV/AIDS, caring for oneself and life after diagnosis of HIV/AIDS in their daily lives. Final considerations: The diagnosis of HIV/AIDS seropositivity in the elderly generates a blend of feelings and fears that lead to food changes, adherence to treatment and the renunciation of daily and social habits, manifested as ways of self-care.

Sub-Saharan Africa bears an inordinate burden of human immunodeficiency virus (HIV) infection/acquired immune deficiency syndrome (AIDS). Reports have shown increased prevalence of clustering of cardiovascular risk factors referred to as metabolic syndrome in treatment-naïve patients and patients on highly active antiretroviral therapy (HAART). In view of the fact that metabolic syndrome is a heterogeneous disorder with substantial variability in the prevalence and component traits within and across populations and the dearth of publications on the prevalence and clinical correlates of metabolic syndrome in people living with HIV/AIDS (PLWHA) in Nigeria, this study was carried out to determine the prevalence and clinical correlates of metabolic syndrome among an HIV-infected outpatient population using the National Cholesterol Education Adult Treatment Panel III (NCEP ATP III), the International Diabetes Federation (IDF), and the Joint Interim Statement (JIS) definitions. We also sought to determine if HAART use and CD4 count level were associated with metabolic syndrome. This cross-sectional study involved 291 (95 men, 196 women) consecutive PLWHA. Anthropometry, blood pressure, fasting plasma glucose, and lipid profile values were determined. The prevalence rates of metabolic syndrome according to the ATP III, IDF, and JIS criteria were 12.7%, 17.2%, and 21.0%, respectively. Metabolic syndrome was significantly associated with female gender (all definitions), body mass index (all definitions), increasing age, and CD4 count (IDF definition). There was no significant association between metabolic syndrome and HAART. The concordance [kappa coefficient (κ)] between the definitions of metabolic syndrome varied between 0.583 and 0.878. The prevalence of metabolic syndrome varied with the criteria used and metabolic syndrome correlates with traditional cardiovascular risk factors rather than HAART-related factors.

The summaries of clinical data and the autopsy materials of 58 patients who died of acquired immunodeficiency syndrome were reviewed to study the spectrum of the pathologic features of this disease in a general hospital. Histologic sections of all organs were routinely obtained. The most affected organs were the lungs and encephalo, those responsible for the immediate cause of death. There were 11 types of microorganisms and 3 types of tumors. Among the microorganisms, the most frequent was the cytomegalovirus and, among tumors, Kaposi's sarcoma. The microorganisms were frequently associated, mainly in the central nervous system. There was also an association of microorganisms with tumors. Many patients presented with suppurative inflammation. Besides these lesions, a lymphocytic depletion of lymphoid organs was observed. The spectrum of pathologic changes in AIDS is vast, and pathologists should be aware of this fact to accurately diagnose the lesions they find. The morphologic lesions are neither unique nor specific for this syndrome, but in this clinical and immunologic setting they are characteristic. It became clear that several microorganisms and tumors sometimes can only be discovered by autopsy, which is an irrefutable proof that despite the modern technology, autopsy is unavoidable for the knowledge of the pathogeny of a disease.

Cytomegalovirus (CMV) retinitis is the most severe intraocular complication that results in total retinal destruction and loss of visual acuity in patients with acquired immunodeficiency syndrome (AIDS). This study aimed to investigate the fundus characteristics, systemic manifestations and therapeutic outcomes of CMV retinitis associated with AIDS. It was a retrospective case series. CMV retinitis was present in 39 eyes (25 patients). Best corrected visual acuities, anterior segment, fundus features, fundus fluorescence angiography (FFA) and CD4(+) T-lymphocyte counts of the patients with CMV retinitis associated with AIDS were analyzed. Intravitreal injections of ganciclovir (400 µg) were performed in 4 eyes (2 patients). Retinal vasculitis, dense, full-thickness, yellow-white lesions along vascular distribution with irregular granules at the border, and hemorrhage on the retinal surface were present in 28 eyes. The vitreous was clear or mildly opaque. Late stage of the retinopathy was demonstrated in 8 eyes characterized as atrophic retina, sclerotic and attenuated vessels, retinal pigment epithelium (RPE) atrophy, and optic nerve atrophy. Retinal detachment was found in 3 eyes. The average CD4(+) T-lymphocyte count in peripheral blood of the patients with CMV retinitis was (30.6 ± 25.3) × 10(6)/L (range, (0 - 85) × 10(6)/L). After intravitreal injections of ganciclovir, visual acuity was improved and fundus lesions regressed. CMV retinitis is the most severe and the most common intraocular complication in patients with AIDS. For the patients with yellow-white retinal lesions, hemorrhage and retinal vasculitis without clear cause, human immunodeficiency virus (HIV) serology should be performed. Routine eye examination is also indicated in HIV positive patients.

The acquired immunodeficiency syndrome (AIDS) epidemic represents a growing challenge for the health care system and for case management models applied to persons with AIDS. The experience of San Francisco highlights some of the issues involved in developing a case management system appropriate to the needs of persons with AIDS, as well as providers, and payers. Dramatic growth in the size and complexity of the AIDS caseload and the involvement of public, health maintenance organization, and community providers has required the increasing formalization and centralization of case management roles. Persistent questions about the definition and goals of case management complicate development of these services. PMID:10312974

Acquired immunodeficiency syndrome in a patient with no known risk factors: a pathological study.

We present the pathological findings in a case of acquired immunodeficiency syndrome (AIDS) in a patient with no known risk factor. Postmortem examination showed klebsiella lung abscess, generalised cytomegalovirus infection, cerebral toxoplasmosis, and a primary cerebral lymphoma. An additional feature was the presence of dilatation of the intrahepatic large bile ducts in association with an atypical distribution of cytomegalovirus. The relation between this case and previously reported cases of AIDS is discussed.

Chinese medicine (CM) has been used in the treatment of human immunodeficiency virus (HIV) infection and acquired immunodeficiency syndrome (AIDS) for 30 years and the demonstrated therapeutic effects of CM, such as reducing plasma HIV viral load, increasing CD4(+)T cell counts, promoting immunity reconstitution, ameliorating symptoms and signs, improving the health related quality of life (HRQOL) and counteracting against the effects of anti-retroviral drugs, were summarized and reviewed in this article. The authors point out that it had been a good opportunity to use CM for the treatment of HIV infection and AIDS in the past and also there are huge challenges ahead for CM research and clinicians to discover more effective CM and its underlying mechanisms for treatment of AIDS.

To review the effects of human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) in terms of its associated comorbid conditions and the side effects of antiretroviral treatment on fertility. PubMed computer search to identify relevant articles. Research institution. None. None. None. Biological alterations in reproductive physiology may account for subfertility in patients infected with HIV. Psychosocial factors in patients with HIV infection may affect their reproductive desires and outcomes. Antiretroviral medications may have direct toxicity on gametes and embryos. Available evidence indicates that fertility treatments can be a safe option for couples with HIV-discordant infection status, although the potential risk of viral transmission cannot be completely eliminated. Because their potential reproductive desires are increasingly becoming a concern in the health care of young HIV-infected patients, additional data are needed to address the effect of HIV and its treatments on their fertility and reproductive outcomes.

Human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) is a multisystem disease that can involve the human eyes. Using ophthalmic examination records from January 2006 to November 2015, we retrospectively reviewed all patients who were diagnosed with HIV/AIDS in our hospital. The study was performed at a tertiary referral center in southern Taiwan. Data included age, gender, ophthalmic examinations, systemic conditions, CD4 cell counts, course, and treatment. Eleven patients were identified as having AIDS with uveitis as their presenting manifestation. All were men, with a mean age of 39.5 ± 11.4 years (range 24-56). The mean CD4 + T-cell counts were 91.7 ± 50.3 cells/μl (range 27-169). Ocular diagnoses included cytomegalovirus (CMV) retinitis in five patients, ocular syphilis in four patients, and ocular toxoplasmosis in two patients. Uveitis resolved in all patients after medical treatment. However, a retinal detachment developed in two eyes in CMV retinitis and one eye in ocular syphilis. Ocular manifestations are among the most common clinical features in patients with HIV/AIDS who have varying clinical presentations that affect almost all ocular structures. This study demonstrated that ocular findings could be an initial manifestation of an underlying disease. Awareness of ocular lesions in HIV/AIDS is important for early recognition and management.

Study Objectives: Cytokine activity and polymorphisms have been associated with sleep outcomes in prior animal and human research. The purpose of this study was to determine whether circulating plasma cytokines and cytokine polymorphisms are associated with the poor sleep maintenance commonly experienced by adults living with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS). Design: Cross-sectional descriptive study. Setting: HIV clinics and community sites in the San Francisco Bay area. Participants: A convenience sample of 289 adults (193 men, 73 women, and 23 transgender) living with HIV/AIDS. Interventions: None. Measurements and Results: A wrist actigraph was worn for 72 h to estimate the percentage of wake after sleep onset (WASO%) and total sleep time (TST), plasma cytokines were analyzed, and genotyping was conducted for 15 candidate genes involved in cytokine signaling: interferon-gamma (IFNG), IFNG receptor 1 (IFNGR1), interleukins (IL1B, IL1R2, IL1R2, IL2, IL4, IL6, IL8, IL10, IL13, IL17A), nuclear factor of kappa light polypeptide gene enhancer in B cells (NFKB1 and NFKB2), and tumor necrosis factor-alpha (TNFA). Controlling for demographic variables such as race and sex, and clinical variables such as CD4+ count and medications, higher WASO% was associated with single nucleotide polymorphisms (SNPs) of IL1R2 rs11674595 and TNFA rs1041981 and less WASO% was associated with IL2 rs2069776. IL1R2 rs11674595 and TNFA rs1041981 were also associated with short sleep duration. Conclusions: This study strengthens the evidence for an association between inflammation and sleep maintenance problems. In this chronic illness population, cytokine polymorphisms associated with wake after sleep onset provide direction for intervention research aimed at comparing anti-inflammatory mechanisms with hypnotic agents for improving sleep maintenance and total sleep time.

The purpose of this study was to determine if older African Americans are disproportionately affected by acquired immunodeficiency syndrome (AIDS), and to review the clinical impact of AIDS and the importance of prevention and treatment efforts. A review of the literature and statistics was obtained using Medline and the AIDS Public Information Data Set offered by the Centers for Disease Control and Prevention. Twenty-seven percent of the U.S. population is above the age of 50, and the number of AIDS cases in this group is growing, with African Americans accounting for the highest proportion of cases and deaths. Testing for HIV may be delayed and symptoms attributed to other illnesses. Though 5% of new cases occur in those over 50, prevention programs, testing, and the perception of risk by providers may be insufficient. There are few research studies on HIV treatment in older patients and no specific guidelines for antiretroviral treatments available. Although death rates for AIDS has been declining, adults over 50 still have the highest mortality rate. Co-morbid conditions, such as heart disease and hypertension, may require taking multiple drugs, which may complicate treatment. Increasing heterosexual transmission rates and a lack of information on HIV reinforces the need for specific prevention programs targeted toward older African Americans. PMID:11991333

Hemophagocytic lymphohistiocytosis (HLH) is a rare and aggressive disease involving immune system over-activation leading to hemophagocytosis. HLH requires early diagnosis and prompt treatment initiation, especially in patients with Acquired Immunodeficiency Syndrome (AIDS). We present a case of a middle-aged male with AIDS and renal failure, who developed HLH secondary to disseminated histoplasmosis. Etoposide chemotherapy as recommended by the HLH 2004 Guidelines was deferred and treatment focused instead on anti-fungal therapy. Anti-retroviral therapy followed thereafter.

Vogt-Koyanagi-Harada (VKH), a multisystem autoimmune bilateral panuveitis with systemic manifestations, is uncommon in immunocompromised patients such as human immunodeficiency virus (HIV)/acquired immunodeficiency disease syndrome (AIDS). We report a rare presentation of VKH in a 45-year-old HIV-positive female on highly active antiretroviral therapy (HAART) who presented with a history of recurrent panuveitis. A diagnosis of probable VKH was made based on ocular and systemic signs and symptoms. She was treated with topical and systemic steroids with close monitoring of CD4 counts and viral loads. After inflammation control, complicated cataract was managed surgically under perioperative steroid cover. VKH in HIV/AIDS has not been reported earlier. This case shows that significant inflammation can be seen even in HIV/AIDS patients on HAART with VKH in spite of moderate CD4 counts. Management is a challenge considering the systemic risks with long-term use of steroids.

Moyamoya disease is an occlusion of the terminal portion of internal carotid arteries and proximal portion of middle and anterior cerebral arteries of unknown origin. Moyamoya syndrome is associated with meningitis, tuberculosis, syphilis, head trauma, head irradiation, brain tumor, von Recklinghausen's disease, tuberous sclerosis, Marfan syndrome, sickle cell anemia, arteriosclerosis, hypertension, and oral contraceptive use. To our knowledge, acquired immunodeficiency syndrome (AIDS) as a cause of moyamoya syndrome has not been reported in an adult population. We report a case of moyamoya syndrome in a patient with AIDS and without other conditions associated with occlusion of the circle of Willis and formation of collateral network at the base of the brain and basal ganglia. We present a case report. A 29-year-old woman with an 8-year history of AIDS on multiple antiretroviral medications presented with recurrent tingling of the left extremities which 1 month later progressed to mild hemiparesis and dysarthria. During the next few months the patient developed progressive cognitive decline and on-and-off fluctuations in the degree of hemiparesis. Brain magnetic resonance imaging showed multiple small subcortical infarct's in both parietal lobes. Magnetic resonance angiography showed occlusion of middle cerebral arteries distal internal carotid arteries, with prominent collateral network. Cerebral angiography confirmed moyamoya pattern. Lumbar puncture showed: white blood cell count 1, red blood cell count 418, protein 56, glucose 53, negative bacterial and acid-fast bacilli smear and culture, negative VDRL test, India ink, cryptococcal antigen, cytology and negative polymerase chain reaction for cytomegalovirus, Epstein-Barr virus, varicella-zoster virus, and herpes simplex virus type 1 and 2. Electroencephalography showed diffuse background slowing. We hypothesize that human immunodeficiency virus (HIV) caused central nervous system vasculitis, which eventually

Continuing expansion of the human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) pandemic has been recognized as an exceptional challenge to global health. Taking highly active antiretroviral treatment (HAART), a confirmed effective treatment, has its limitations. While a much cheaper and potential treatment-the Chinese medicine (CM) has not been paid enough attention from the worldwide. We explained the CM viewpoints about pathology and etiology to answer some questions about whether and how CM can treat AIDS. Some herbal formulae and their targeted patterns and common symptoms were also introduced. Chinese government has realized the important role of CM as an independent therapy for early management, bolstering immune-system functions depressed by HIV, and has funded large randomized double-blind controlled clinical trials to more accurately assess the benefits, and valued the fundamental research to establish a quantitative standardization of pattern diagnosis. Researchers of CM are looking for cooperation with all the world's top experts in the areas of AIDS and immunity to strive for victories in the fight against AIDS.

Toxoplasmosis is an important cause of enhancing brain lesions in patients with acquired immunodeficiency syndrome (AIDS), and it is typically associated with low CD4-lymphocyte counts. Extensive toxoplasma encephalitis when the CD4-lymphocyte count is above 100 cells/µl is unusual. Cavitary lung lesions are also not typically associated with toxoplasmosis. Here, we present a case of toxoplasmosis associated with extensive brain masses and cavitary lung lesions, both of which improved with directed toxoplasmosis therapy, in an AIDS patient with a CD4 cell count of 120 cells/µl.

Cardiovascular disease (CVD) is an increasing cause of morbidity and mortality in human immunodeficiency virus (HIV)-infected adults; however, this population may be less likely to receive interventions during hospitalization for acute coronary syndrome (ACS). The degree to which this disparity can be attributed to poorly controlled HIV infection is unknown.In this large cohort study, we used the National Inpatient Sample (NIS) to compare rates of cardiac procedures among patients with asymptomatic HIV-infection, symptomatic acquired immunodeficiency syndrome (AIDS), and uninfected adults hospitalized with ACS from 2009 to 2012. Multivariable analysis was used to compare procedure rates by HIV status, with appropriate weighting to account for NIS sampling design including stratification and hospital clustering.The dataset included 1,091,759 ACS hospitalizations, 0.35% of which (n = 3783) were in HIV-infected patients. Patients with symptomatic AIDS, asymptomatic HIV, and uninfected patients differed by sex, race, and income status. Overall rates of cardiac catheterization and revascularization were 53.3% and 37.4%, respectively. In multivariable regression, we found that relative to uninfected patients, those with symptomatic AIDS were less likely to undergo catheterization (odds ratio [OR] 0.48, confidence interval [CI] 0.43-0.55), percutaneous coronary intervention (OR 0.69, CI 0.59-0.79), and coronary artery bypass grafting (0.75, CI 0.61-0.93). No difference was seen for those with asymptomatic HIV relative to uninfected patients (OR 0.93, CI 0.81-1.07; OR 1.06, CI 0.93-1.21; OR 0.88, CI 0.72-1.06, respectively).We found that lower rates of cardiovascular procedures in HIV-infected patients were primarily driven by less frequent procedures in those with AIDS.

Dermatologists are often the first-line specialists who recognize and diagnose human immunodeficiency virus (HIV) infection because of pathognomic skin signs. It is therefore important to investigate attitudes and knowledge regarding HIV/acquired immunodeficiency syndrome (AIDS) amongst dermatological patients in order to provide information for dermatologists and to draw their attention to the issues. Awareness of HIV/AIDS, its prevention, and hypothetical behaviour were surveyed in dermatological outpatients. The anonymous cross-sectional survey was conducted with consecutive German-speaking outpatients aged 18-65 years, who registered at the dermatological outpatient's clinic (excluding venereology, genitourinary or HIV medicine) of the University of Munich (Germany). Three hundred forty-seven (77.5%) questionnaires were accepted for analysis. Most of the patients knew about HIV incurability (89.4%), HIV transmissibility during needle sharing (95.3%), or vaginal (87.4%) and anal intercourse (79.5%), as well as about HIV prevention by condom use (97.8%), and use of single needles (76.2%). However, knowledge gaps and misconceptions were detected regarding the risk of HIV transmission during oral sex, and the efficacy of sexual fidelity and avoidance of blood transfusions in HIV prevention. The lowest knowledge level (< 50% correct answers) was detected in patients aged 50-59 years, in unemployed, divorced/widowed, and in those without or with incomplete school education. Patient education about HIV/AIDS in dermatological ambulant settings should be performed differentially with regard to socio-demographic factors, and focused on the topic of oral sexual HIV transmission and on some other specific misconceptions.

Use of etanercept in human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) patients.

Etanercept (Enbrel, Amgen, Thousand Oaks, CA), a soluble p75 tumor necrosis factor receptor:FC (TNFR:FC) fusion protein for plasma cytokines, specifically tumor necrosis factor-alpha (TNF-alpha), is used in the treatment of immune-mediated rheumatic diseases. To our knowledge, the use of etanercept in patients with human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) is relatively uncommon. The main purpose of this short review is to examine the safety of etanercept in patients with HIV/AIDS. A Medline search was conducted using the keywords etanercept and HIV and/or AIDS for any published articles between 1966 to the present (September 2004). A case report, one case series, and one clinical trial pertained to the use of etanercept in HIV patients. No reports were found on the use of etanercept in AIDS. In addition, two case reports were found documenting the use of infliximab in HIV patients. Preliminary reports indicate that the administration of etanercept does not appear to increase the morbidity or mortality rates in HIV. The inhibition of TNF-alpha may actually improve the symptoms of HIV/AIDS-associated aphthous ulcers, cachexia, dementia, fatigue, and fever, as well as help manage concomitant rheumatic diseases and psoriasis. The use of etanercept shows promise for applications in disease management in patients with HIV/AIDS. Continued research efforts are necessary to establish the long-term safety and efficacy of etanercept and other biologic agents in this patient population.

Abstract Although discontinuation of suppressive antifungal therapy for acquired immunodeficiency syndrome (AIDS)-associated histoplasmosis is accepted for patients with immunologic recovery, there have been no published studies of this approach in clinical practice, and minimal characterization of individuals who relapse with this disease. We performed a multicenter retrospective cohort study to determine the outcome in AIDS patients following discontinuation of suppressive antifungal therapy for histoplasmosis. Ninety-seven patients were divided into a physician-discontinued suppressive therapy group (PD) (38 patients) and a physician-continued suppressive therapy group (PC) (59 patients). The 2 groups were not statistically different at baseline, but at discontinuation of therapy and at the most recent follow-up there were significant differences in adherence to therapy, human immunodeficiency virus (HIV) RNA, and urinary Histoplasma antigen concentration. There was no relapse or death attributed to histoplasmosis in the PD group compared with 36% relapse (p < 0.0001) and 5% death (p = 0.28) in the PC group. Relapse occurred in 53% of the nonadherent patients but not in the adherent patients (p < 0.0001). Sixty-seven percent of patients with initial central nervous system (CNS) histoplasmosis relapsed compared to 15% of patients without CNS involvement (p = 0.0004), which may be accounted for by nonadherence. In addition, patients with antigenuria above 2.0 ng/mL at 1-year follow-up were 12.82 times (95% confidence interval, 2.91–55.56) more likely to relapse compared to those with antigenuria below 2.0 ng/mL. Discontinuation of antifungal therapy was safe in adherent patients who completed at least 1 year of antifungal treatment, and had CD4 counts >150 cells/mL, HIV RNA <400 c/mL, Histoplasma antigenuria <2 ng/mL (equivalent to <4.0 units in second-generation method), and no CNS histoplasmosis.

Depression can be a chronic and impairing illness in people with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome. Large randomized studies of newer selective serotonin reuptake inhibitors such as escitalopram in the treatment of depression in HIV, examining comparative treatment efficacy and safety, have yet to be done in HIV-positive patients. This was a fixed-dose, placebo-controlled, randomized, double-blind study to investigate the efficacy of escitalopram in HIV-seropositive subjects with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, major depressive disorder. One hundred two participants were randomly assigned to either 10 mg of escitalopram or placebo for 6 weeks. An analysis of covariance of the completers found that there was no advantage for escitalopram over placebo on the Montgomery-Asberg Depression Rating Scale (p = 0.93). Sixty-two percent responded to escitalopram and 59% responded to placebo on the Clinical Global Impression Scale. Given the relatively high placebo response, future trials in this area need to be selective in participant recruitment and to be adequately powered.

To evaluate the histomorphometric skin changes over aging patients with autopsied acquired immunodeficiency syndrome (AIDS). In 29 skin fragments of autopsied elderly (older than 50 years) and nonelderly patients with AIDS, epidermal thickness, the number of layers, the diameter of cells, the percentage of collagen and elastic fibers in the dermis, and the number and morphology of Langerhans cells were assessed. Statistical analysis was performed by SigmaStat 2.03 program. The thickness of the epidermis (92.55 × 158.94 μm), the number of layers (7 × 9 layers), and the diameter of the cells (13.27 × 17.6 μm) were statistically lower among the elderly. The quantity of collagen fibers (9.68 × 14.11%) and elastic fibers (11.89 × 15.31%) was also significantly lower in the elderly. There was a decrease in total (10.61 × 12.38 cel/mm(2)) and an increase in immature Langerhans cells (6.31 × 4.98 cel/mm(2)) in elderly patients with AIDS. The aging of the skin of patients with AIDS is amended in different histomorphometric aspects, the epidermis constituents suffer less pronounced changes in normal aging, and the dermis has more intense changes in elastic fibers and collagen.

After the emergence of the human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS), the number of visceral leishmaniasis (VL)-HIV/AIDS coinfections has increased worldwide. Herein, we assessed the usefulness of an rK39-based immunochromatographic test (rK39 ICT) (DiaMed-IT LEISH(®); DiaMed AG, Cressier-sur-Morat, Switzerland) and a latex agglutination test (KAtex; Kalon Biological, Guildford, United Kingdom) for urinary antigen detection to diagnose VL in 15 HIV/AIDS patients from northeastern Brazil. VL diagnosis was based on clinical findings, cytology, serology, parasite DNA, and/or urinary antigen detection. VL was confirmed in seven out of 15 HIV/AIDS patients. Only three patients were positive in bone marrow cytology, three patients were conventional polymerase chain reaction (PCR) positive, while six were real-time PCR positive. All patients were direct agglutination test (DAT) (Royal Tropical Institute, Amsterdam, The Netherlands) positive; of these, four were positive by rK39 ICT and five by KAtex. Large-scale studies are needed to validate the use of the KAtex in the national public health laboratory network in Brazil, aiming at improving the diagnosis of VL in HIV/AIDS patients in this country. © The American Society of Tropical Medicine and Hygiene.

Science and ethics of human immunodeficiency virus/acquired immunodeficiency syndrome controversies in Africa.

PubMed

Brewster, David

2011-09-01

The human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) epidemic in Africa has raised important ethical issues for both researchers and clinicians. The most notorious controversy has been related to the zidovudine (AZT) trials in Africa in the late 1990s, in which the control groups were given a placebo rather than an effective drug to prevent vertical transmission. This raised concerns in the sponsoring country about exploitation of subjects, injustice and an ethical double standard between donor countries and resource-poor settings. However, the real double standard is between clinical practice standards in Western versus African countries, which must be addressed as part of the increasing global inequity of wealth both between countries and also within countries. There are important limitations to ethical declarations, principles and guidelines on their own without contextual ethical reasoning. The focus on research ethics with the HIV epidemic has led to a relative neglect of ethical issues in clinical practice. Although the scientific advances in HIV/AIDS have changed the ethical issues since the 1990s, there has also been progress in the bioethics of HIV/AIDS in terms of ethical review capability by local committees as well as in exposure to ethical issues by clinicians and researchers in Africa. However, serious concerns remain about the overregulation of research by bureaucratic agencies which could discourage African research on specifically African health issues. There is also a need for African academic institutions and researchers to progressively improve their research capacity with the assistance of research funders and donor agencies. © 2011 The Author.

Cystoisospora belli in patients with the acquired immunodeficiency syndrome (AIDS) has been described as cause of chronic diarrhea and disseminated cystoisosporosis. Diagnosis of intestinal cystoisosporosis can be achieved at the tissue level in the villus epithelium of the small bowel. Disseminated cystoisosporosis is diagnosed by microscopy identification of unizoite tissue cysts in the lamina propria of the intestine. We report a case of disseminated cystoisosporosis in a human immunodeficiency virus (HIV)-infected patient with detection of parasitemia. We studied a 39-year old patient with AIDS and chronic diarrhea by analysis of stool and duodenal biopsy samples. Blood samples were also collected and examined by light microscopy and molecular techniques for C. belli DNA detection. The unizoite tissue cyst stages were present in the lamina propria, with unsporulated oocysts in feces. Zoites were present in blood smears and DNA of C. belli was detected in blood samples. Our study identified a new stage in the life cycle of C. belli. Detection of parasitemia is a novel and noninvasive tool for diagnosis of disseminated cystoisosporosis.

To investigate the patterns and risk factors of the ocular manifestations of acquired immunodeficiency syndrome (AIDS) and their correlation with CD4+ count in the era of highly active antiretroviral therapy (HAART). This retrospective study examined 127 AIDS patients who presented to Soonchunhyang University Hospital. Data were collected from patient interviews, clinical examinations, and laboratory investigations. Ophthalmologic examinations included the best-corrected visual acuity, intraocular pressure, anterior segment and adnexal examination, and dilated fundus examination. Of the 127 patients with AIDS, 118 were on HAART and 9 were not. The mean CD4+ count was 266.7 ± 209.1 cells/µL. There were ocular manifestations in 61 patients (48.0%). The incidence of anterior segment manifestations was higher than posterior segment manifestations at 28.3% and 19.7%, respectively. The mean CD4+ count was significantly (p < 0.05) lower in the patients with posterior versus anterior segment ocular manifestations. The most common ocular manifestation was retinal microvasculopathy (15.0%), followed by keratoconjunctivitis sicca (14.2%), conjunctival microvasculopathy (9.4%), cytomegalovirus retinitis (3.1%), herpes zoster ophthalmicus (2.4%), and blepharitis (1.6%). Retinal microvasculopathy and cytomegalovirus retinitis were common in patients with CD4+ counts <200 cells/µL, while keratoconjunctivitis sicca and conjunctival microvasculopathy were common in patients with CD4+ counts of 200 to 499 cells/µL. There was a significant (p < 0.05) association between ocular manifestation and CD4+ count or age. The introduction of HAART has changed the landscape of ocular presentations in patients with AIDS. In this study, anterior segment and external ocular manifestations occurred more frequently than posterior segment manifestations. Also, the mean CD4+ count was significantly lower in patients with posterior segment ocular manifestations versus anterior segment ocular

A case of bilateral progressive outer retinal necrosis occurred after herpes zoster ophthalmicus in a patient with acquired immunodeficiency syndrome. This case does not correspond to the classical picture of progressive outer retinal necrosis. The disease led to blindness despite intravenous therapy with acyclovir and foscarnet. PCR could not identify any virus in the aqueous humour, but VZV is evidenced in cerebrospinal fluid. Acute retinal necrosis is now clearly defined by the American Uveitis Society, which should allow to determine its incidence and risk factors. Herpes zoster usually precedes the acute outer retinal necrosis. The infectious theory (VZV, HSV, CMV) widely prevails over the immune theory. We prefer the virus genome identification in the aqueous humor or in the vitreous by PCR to confirm diagnosis rather than the specific antibody titration. Therapy consists in acyclovir, foscarnet and ganciclovir. But whatever the treatment, the visual prognosis is poor.

Systemic lupus erythematosus (SLE) is a systemic inflammatory disease of connective tissue with an unknown etiology and a rich clinical picture with involvement of multiple organs. Given the rich symptomatology, application of the current classification criteria is associated with a significant risk of attributing symptoms of other pathologies to lupus and/or other connective tissue disease. Inherited and acquired immune deficiencies may sometimes demonstrate a lupus-like clinical symptomatology. In this work we reviewed 4 of cases referred to the Department of Internal Diseases and Rheumatology of the Silesian Medical University in Katowice with suspected or confirmed systemic lupus erythematosus. A positive anti-HIV antibody test led to the diagnosis of the acquired immunodeficiency syndrome (AIDS). Due to the close similarity of the clinical picture and the presence of antinuclear antibodies in both diseases, the authors postulate that the anti-HIV antibody test should be done routinely in patients with connective tissue diseases.

Acquired Immunodeficiency Syndrome (Aids) was initially related to HIV-associated wasting syndrome, and its metabolic disturbances to altered body composition. After Highly Active Antiretroviral Therapy (HAART) was started, malnutrition has declined and HIV-associated lipodystrophy syndrome has emerged as an important metabolic disorder. Aids is also characterized by hormonal disturbances, principally in growth hormone/insulin-like growth factor 1 (GH/IGF-1) axis. The use of recombinant human GH (hrGH) was formerly indicated to treat wasting syndrome, in order to increase lean body mass. Even though the use of hrGH in lipodystrophy syndrome has been considered, the decrease in insulin sensitivity is a limitation for its use, which has not been officially approved yet. Diversity in therapeutic regimen is another limitation to its use in Aids patients. The present study has reviewed the main HIV-related endocrine-metabolic disorders as well as the use of hrGH in such conditions.

Research on adults with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) has suggested that psychiatric and substance abuse comorbidities are prevalent in this population, and that these may sometimes be associated with use of antiretroviral therapy (ART) and adherence. For adolescents with HIV/AIDS, much less is known about patterns of mental health comorbidity, and even fewer data are available that compare them to socioeconomically comparable youth without HIV/AIDS. Using medical and pharmacy data from 1999 to 2000 Medicaid claims (Medicaid Analytic Extract) from 4 states for beneficiaries aged 12 to 17 years, we identified 833 youth under care for HIV/AIDS meeting study criteria within the HIV/AIDS group, receipt of ART was less likely for youth who had diagnoses of substance abuse, conduct disorders, or emotional disorders than for others. Once ART was initiated, adherence did not significantly differ between adolescents living with a psychiatric condition, and those who were not, with the exception of an association between conduct disorder and lower adherence. Among those with HIV/AIDS, ART use and adherence were more common among youth with higher rates of service use, regardless of psychiatric status. Associations between race and adherence varied by gender: compared with their white counterparts, minority girls had lower, and minority boys had higher adherence.

As newer methods of management are made available, and accessible, survival rates with human immunodeficiency virus (HIV) are increasing. This means that chronic, metabolic complications of HIV are becoming more frequent in clinical practice, as acute morbidity is controlled. Management of HIV/acquired immunodeficiency syndrome (AIDS) is gradually expanding to include these chronic and metabolic complications of the disease, and the adverse effects associated with its treatments, including diabetes. Unfortunately, no guidelines are available to help the medical practitioners choose appropriate therapy for patients with these conditions. The aim of the South Asian Consensus Guidelines is to provide evidence-based recommendations to assist healthcare providers in the rational management of type 2 diabetes mellitus in patients with HIV. The development of these guidelines used systematic reviews of available evidence to form its key recommendations. These guidelines and associated review of literature represent a compilation of available knowledge regarding rational management of diabetes in HIV. Patients of diabetes with concomitant HIV infection are managed optimally with insulin therapy and judicious use of highly active antiretroviral therapy with suitable alternatives is also recommended. These guidelines should prove helpful to physicians, not only in South Asia, but also across the globe, while managing patients with coexistent HIV and diabetes. PMID:22028994

Growth of Cryptococcus neoformans from the sputum of patients with acquired immunodeficiency syndrome may be obscured by oral contamination with Candida albicans on conventional media. We prospectively compared direct plating of sputum and urine onto birdseed agar and compared birdseed agar plating with plating onto Mycosel and Sabouraud dextrose agar cultures. Thirty-two sputum and three urine specimens were compared. C. neoformans was isolated from five specimens. In two specimens, one of sputum and one of urine, C. neoformans was detected only on the birdseed agar plate because of overgrowth on the conventional media by C. albicans. C. neoformans produced dark colonies on birdseed agar, unlike C. albicans, which produces white colonies. The use of birdseed agar as the primary culture medium for sputum and urine specimens from patients with acquired immunodeficiency syndrome increases sensitivity for C. neoformans.

Diagnostic bone marrow aspiration, biopsy, and culture are useful procedures in the evaluation of patients with suspected or proven acquired immunodeficiency syndrome (AIDS) who are febrile. In as many as one fourth of these patients, the information provided by the bone marrow examination may establish a diagnosis of a disseminated opportunistic infection when other studies are not informative. We have also discovered a previously unreported association between thrombocytopenia and the presence of bone marrow granulomas in our patients with AIDS and suggest that thrombocytopenia may be a clue to enable the clinician to predict a positive bone marrow result more accurately. The explanation for this apparent association remains to be elucidated.

Purpose To investigate the patterns and risk factors of the ocular manifestations of acquired immunodeficiency syndrome (AIDS) and their correlation with CD4+ count in the era of highly active antiretroviral therapy (HAART). Methods This retrospective study examined 127 AIDS patients who presented to Soonchunhyang University Hospital. Data were collected from patient interviews, clinical examinations, and laboratory investigations. Ophthalmologic examinations included the best-corrected visual acuity, intraocular pressure, anterior segment and adnexal examination, and dilated fundus examination. Results Of the 127 patients with AIDS, 118 were on HAART and 9 were not. The mean CD4+ count was 266.7 ± 209.1 cells/µL. There were ocular manifestations in 61 patients (48.0%). The incidence of anterior segment manifestations was higher than posterior segment manifestations at 28.3% and 19.7%, respectively. The mean CD4+ count was significantly (p < 0.05) lower in the patients with posterior versus anterior segment ocular manifestations. The most common ocular manifestation was retinal microvasculopathy (15.0%), followed by keratoconjunctivitis sicca (14.2%), conjunctival microvasculopathy (9.4%), cytomegalovirus retinitis (3.1%), herpes zoster ophthalmicus (2.4%), and blepharitis (1.6%).

This study aimed to determine whether the human immunodeficiency virus (HIV) exists in giant idiopathic esophageal ulcers in the patients with acquired immune deficiency syndrome (AIDS). 16 AIDS patients with a primary complaint of epigastric discomfort were examined by gastroscopy. Multiple and giant esophageal ulcers were biopsied and analyzed with pathology staining and reverse transcription-polymerase chain reaction (RT-PCR) to determine the potential pathogenic microorganisms, including HIV, cytomegalovirus (CMV) and herpes simplex viruses (HSV). HIV was detected in ulcer samples from 12 out of these 16 patients. Ulcers in 2 patients were infected with CMV and ulcers in another 2 patients were found HSV positive. No obvious cancerous pathological changes were found in these multiple giant esophageal ulcer specimens. HIV may be one of the major causative agents of multiple benign giant esophageal ulcers in AIDS patients.

Characterization of the gag/fusion protein encoded by the defective Duplan retrovirus inducing murine acquired immunodeficiency syndrome.

Murine acquired immunodeficiency syndrome is induced by a defective retrovirus. Sequencing of this defective viral genome revealed a long open reading frame which encodes a putative gag/fusion protein, N-MA-p12-CA-NC-COOH, (D. C. Aziz, Z. Hanna, and P. Jolicoeur, Nature (London) 338:505-508, 1989). We raised a specific antibody to the unique p12 domain of this gag fusion precursor, Pr60gag. We found that Pr60gag was indeed encoded by the defective viral genome both in cell-free translation reticulocyte extracts and in infected mouse fibroblasts. Pr60gag was found to be myristylated, phosphorylated, and attached to the cell membrane, like other helper murine leukemia virus (MuLV) gag precursors. Pr60gag was not substantially cleaved within the nonproducer cells and was not released from these cells. However, in the presence of helper MuLV proteins, it formed phenotypically mixed particles. In these particles, Pr60gag was only partially cleaved. In helper MuLV-producing cells harboring the defective virus, a gag-related p40 intermediate was generated both intracellularly and extracellularly. In these cells, Pr60gag appeared to behave as a dominant negative mutant, interfering with proper cleavage of helper Pr65gag. Our data indicate that Pr60gag is a major (and possibly the only) gene product of the defective murine acquired immunodeficiency syndrome virus and is likely to harbor some determinants of pathogenicity of this virus.

Bernal-Cano, F; Joseph, J T; Koralnik, I J

2007-10-01

Progressive multifocal leukoencephalopathy (PML) is a deadly demyelinating disease of the central nervous system, which occurs in immunosuppressed individuals. This disease is caused by a reactivation of the polyomavirus JC (JCV). Clinical presentation can be variable from patient to patient as lesions can occur anywhere in the CNS white matter; however, they appear to spare the optic nerves and the spinal cord. The authors present a case of PML in the setting of acquired immunodeficiency syndrome (AIDS) who developed PML lesions in the spinal cord, discovered during the postmortem examination. This finding is significant because PML has recently been diagnosed in patients with multiple sclerosis (MS) treated with the novel immunomodulatory medication natalizumab. Indeed, spinal cord lesions are frequent in MS. Therefore clinicians should be aware that in addition to the brain, PML may also affect the spinal cord white matter.

An Increased Risk of Osteoporosis during Acquired Immunodeficiency Syndrome

PubMed Central

2004-01-01

Osteoporosis is characterized by decreased bone mineral density and mechanistic imbalances of bone tissue that may result in reduced skeletal strength and an enhanced susceptibility to fractures. Osteoporosis in its most common form affects the elderly (both sexes) and all racial groups of human beings. Multiple environmental risk factors like acquired immune deficiency syndrome (AIDS) are believed to be one of the causes of osteoporosis. Recently a high incidence of osteoporosis has been observed in human immunodeficiency virus (HIV) infected individuals. The etiology of this occurrence in HIV infections is controversial. This problem seems to be more frequent in patients receiving potent antiretroviral therapy. In AIDS, the main suggested risk factors for the development of osteoporosis are use of protease inhibitors, longer duration of HIV infection, lower body weight before antiretroviral therapy, high viral load. Variations in serum parameters like osteocalcin, c-telopeptide, levels of elements like Calcium, Magnesium, Phosphorus, concentration of vitamin-D metabolites, lactate levels, bicarbonate concentrations, amount of alkaline phosphatase are demonstrated in the course of development of osteoporosis. OPG/RANKL/RANK system is final mediator of bone remodeling. Bone mineral density (BMD) test is of added value to assess the risk of osteoporosis in patients infected with AIDS. The biochemical markers also aid in this assessment. Clinical management mostly follows the lines of treatment of osteoporosis and osteopenia. PMID:15912194

The orbital manifestations of acquired immunodeficiency syndrome(AIDS) are uncommon. To provide a review of orbital manifestations of AIDS, the predisposing factors, investigations, treatment and outcome. Meticulous and systematic literature search of Pubmed to identify manuscripts describing orbital manifestations of AIDS was done and the articles were reviewed.The keywords used in the search were “orbit and AIDS”, “HIV positive and orbit”,“orbit manifestations in AIDS”, “orbital disease and AIDS” and “orbital infections and AIDS”. The orbital involvement in AIDS may present with opportunistic infections from organisms like fungi, viruses, bacteria and protozoa or with malignancies like Kaposi’s sarcoma, squamous cell carcinoma, smooth muscle cell tumors and lymphoma.The predisposing factors for orbital involvement in AIDS are low CD4+ cell count and the immunosuppressive states like diabetes, diabetic ketoacidosis, intravenous drug abuse and neutropenia. A patient may present with fever, headache, nausea, vomiting,decreased vision, ocular pain, and, in cases of mass formation, there is periorbital swelling, axial proptosis, globe displacement and swollen optic disc. Radiologically,mass formation, orbital bony destruction, and spread of disease to contiguous structures including the central nervous system may be seen. The medical management includes therapy for infection and HIV-1 protease inhibitors (highly active antiretroviral therapy)to suppress HIV-1 replication. For tumors, radical surgery including debulking followed by postoperative radiotherapy is generally needed. Orbital involvements with AIDS in any form, infective or malignancy, causes significant morbidity and mortality and should be diagnosed and managed as early as possible.

We briefly review findings from Brazilian settings where the human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) epidemic among injection drug users (IDUs) seems to be decreasing, highlighting recent findings from Rio de Janeiro and discussing methodological alternatives. Former analyses using serologic testing algorithm for recent HIV seroconversion have shown that HIV incidence has been low in IDUs recruited by two different surveys carried out in Rio, where low injection frequencies and infection rates have been found among new injectors. The proportion of AIDS cases among IDUs in Rio has been fairly modest, compared to São Paulo and especially to the southernmost states. Notwithstanding, the interpretation of findings from serial surveys constitutes a challenge, magnified in the assessment of HIV spread among IDUs due to the dynamic nature of the drug scenes and limitations of sampling strategies targeting hard-to-reach populations. Assessment of epidemic trends may profit from the triangulation of data, but cannot avert biases associated with sampling errors. Efforts should be made to triangulate data from different sources, besides exploring specific studies from different perspectives. In an attempt to further assess the observed trends, we carried out original analyses using data from Brazilian AIDS databank.

Because herbal compatibility is one of the most important reasons why Traditional Chinese Medcine (TCM) formulas are effective for acquired immunodeficiency syndrome (AIDS), our study aimed to determine the compatibility of herbs based on published AIDS clinical research in Chinese periodicals. To achieve this aim, we designed a new data-mining algorithm according to TCM data characteristics. We found 25 clinical AIDS studies, all using Chinese herbs for treatment, in the Traditional Chinese Medicine Database System, and information on diagnosis and treatment was extracted. To find out herbal compatibility, especially the formulae for herbal combinations, we proposed an improved association rule algorithm based on the frequency of combinations. In this algorithm, all the compatibility relationships were displayed in a tree structure, by which the relationship between formulas and their derivation could be clearly inferred. Data analysis showed that approximately 100 herbs have been used for treating AIDS. Based on the whole herb compatibility tree, we calculated a basic formula for AIDS: Huang Qi combined with Ren Shen, Fu Ling, Bai Zhu, Bai Zhu, Dang Gui, and Bai Shao. This formula, deriving from most of clinical prescriptions, and was chosed by most of clinicians for AIDS treatment. From data mining we found that Qi replenishment and detoxification were the main treatment principles, which coincided with the AIDS pathological mechanism in which immune function is destroyed by human immunodeficiency virus (HIV). Our data-mining results suggest that the core TCM treatment of AIDS is replenishing Qi and detoxification, by which AIDS patients' immune system may be enhanced. Compatibility of Huang Qi with some frequently-used herbs have shown real efficacy in clinical practice, which warrants pharmacological research in the future.

Treatment of infectious complications of acquired immunodeficiency syndrome.

Furio, M M; Wordell, C J

1985-01-01

The infectious complications of the acquired immunodeficiency syndrome (AIDS) are discussed, and the conventional and nonconventional therapies used for these infections are reviewed. The infections most commonly encountered in patients with AIDS are Pneumocystis carinii pneumonia (58%), Candida esophagitis (31%), toxoplasmosis (21%), cytomegalovirus infections (15%), and herpes-simplex virus infections (12%). Pneumocystis carinii pneumonia is the most common life-threatening process in these patients. Trimethoprim-sulfamethoxazole (TMP-SMZ) is considered the drug of choice for its treatment. Oral candidiasis often indicates the progression to AIDS in the high-risk populations of homosexual or bisexual men, intravenous drug abusers, and individuals with hemophilia. Nystatin suspension is commonly used to treat oral candidiasis, while Candida esophagitis demands systemic therapy with ketoconazole. Toxoplasmosis most commonly manifests itself in patients with AIDS as a cerebral mass lesion. The recommended therapy includes sulfadiazine and pyrimethamine. AIDS patients frequently experience protozoal invasion of the intestinal tract with Giardia lamblia, Isospora belli, and Cryptosporidium muris. Various drugs have been tried for these infections, including quinacrine hydrochloride, metronidazole, TMP-SMZ, and spiramycin. Cytomegalovirus (CMV) infections commonly involve the lungs, gastrointestinal tract, eyes, brain, and nervous system. Attempts to treat these disseminated CMV infections with antiviral agents, including acyclovir, have not been successful. However, acyclovir has been found beneficial in the treatment of herpes-simplex virus infections. Multiple infectious complications may occur in patients with AIDS as a result of the cellular-immune deficiency associated with this disease. Until more research is done with AIDS patients, therapy must be based on the data available from the treatment of these infections in immunosuppressed patients without AIDS.

Histoplasma capsulatum var. capsulatum infection is rare outside disease-endemic areas. Clinical presentation and outcome of acquired immunodeficiency syndrome-related histoplasmosis are unknown in non-endemic areas with wide access to highly active anti-retroviral therapy (HAART). Retrospective analysis of cases recorded at the French National Reference Center for Mycoses and Antifungals during two decades: pre-HAART (1985-1994) and HAART (1997-2006). Clinical features and outcome of all adults with proven acquired immunodeficiency syndrome-related histoplasmosis were compared between the two periods. One hundred four patients were included (40 during the pre-HAART era and 64 during the HAART era). Diagnosis was established a mean of 62 days after onset of symptoms. One-year overall mortality rates decreased from 53% (pre-HAART era) to 22% (HAART era). Diagnosis during the pre-HAART era and an older age were the only independent factors associated with death. Histoplasmosis is a rare invasive fungal infection outside disease-endemic areas. Its prognosis improved significantly during the HAART era.

Human immunodeficiency virus and acquired immunodeficiency syndrome: correlation but not causation.

PubMed Central

Duesberg, P H

1989-01-01

AIDS is an acquired immunodeficiency syndrome defined by a severe depletion of T cells and over 20 conventional degenerative and neoplastic diseases. In the U.S. and Europe, AIDS correlates to 95% with risk factors, such as about 8 years of promiscuous male homosexuality, intravenous drug use, or hemophilia. Since AIDS also correlates with antibody to a retrovirus, confirmed in about 40% of American cases, it has been hypothesized that this virus causes AIDS by killing T cells. Consequently, the virus was termed human immunodeficiency virus (HIV), and antibody to HIV became part of the definition of AIDS. The hypothesis that HIV causes AIDS is examined in terms of Koch's postulates and epidemiological, biochemical, genetic, and evolutionary conditions of viral pathology. HIV does not fulfill Koch's postulates: (i) free virus is not detectable in most cases of AIDS; (ii) virus can only be isolated by reactivating virus in vitro from a few latently infected lymphocytes among millions of uninfected ones; (iii) pure HIV does not cause AIDS upon experimental infection of chimpanzees or accidental infection of healthy humans. Further, HIV violates classical conditions of viral pathology. (i) Epidemiological surveys indicate that the annual incidence of AIDS among antibody-positive persons varies from nearly 0 to over 10%, depending critically on nonviral risk factors. (ii) HIV is expressed in less than or equal to 1 of every 10(4) T cells it supposedly kills in AIDS, whereas about 5% of all T cells are regenerated during the 2 days it takes the virus to infect a cell. (iii) If HIV were the cause of AIDS, it would be the first virus to cause a disease only after the onset of antiviral immunity, as detected by a positive "AIDS test." (iv) AIDS follows the onset of antiviral immunity only after long and unpredictable asymptomatic intervals averaging 8 years, although HIV replicates within 1 to 2 days and induces immunity within 1 to 2 months. (v) HIV supposedly causes AIDS

HIV-2 and its role in conglutinated approach towards Acquired Immunodeficiency Syndrome (AIDS) Vaccine Development.

Acquired Immunodeficiency Syndrome (AIDS) is one of the most critically acclaimed endemic diseases, caused by two lentiviruses HIV-1 and 2. HIV-2 displays intimate serological and antigenic resemblance to Simian Immunodeficiency Virus (SIV) along with less pathogenicity, lower infectivity and appreciable cross reactivity with HIV-1 antigens. The present era is confronted with the challenge to fabricate a vaccine effective against all clades of both the species of HIV. But vaccine development against HIV-1 has proven highly intricate, moreover the laborious and deficient conventional approaches has slackened the pace regarding the development of new vaccines. These concerns may be tackled with the development of HIV-2 vaccine as a natural control of HIV-1 that has been found in ancestors of HIV-2 i.e. African monkeys, mangabeys and macaques. Thereby, suggesting the notion of cross protection among HIV-2 and HIV-1. Assistance of bioinformatics along with vaccinomics strategy can bring about a quantum leap in this direction for surpassing the bottleneck in conventional approaches. These specifics together can add to our conception that HIV-2 vaccine design by in silico strategy will surely be a constructive approach for HIV-1 targeting.

A Pneumocystis jiroveci infection-associated mass clinically mimicking a malignancy (ie, pseudotumor) is rare and usually occurs in the lung in association with Pneumocystis pneumonia. Pneumocystis jiroveci pseudotumors of the small intestine are extremely rare and represent an unusual form of disseminated P jiroveci infection. We present a case of small-intestine P jiroveci pseudotumor as an acquired immunodeficiency syndrome-presenting illness in a patient with coinfection with cytomegalovirus, no pulmonary symptoms, and no known risk factors for human immunodeficiency virus infection. This case reinforces the potential importance of cytomegalovirus coinfection in the disseminated form of Pneumocystis infection and illustrates the importance of an expanded differential diagnosis when confronted with a clinically atypical mass lesion.

Histoplasmosis has attained increasing relevance in the past 3 decades because of the appearance of the human immunodeficiency virus (HIV). In most immunocompetent persons, the infection is asymptomatic or can produce a respiratory condition with symptoms and radiological images similar to those observed in pulmonary tuberculosis; in non-HIV+ immunocompromised patients, it can cause respiratory symptoms or evolve into a disseminated infection. The same can occur in acquired immunodeficiency syndrome (AIDS) patients. We have observed a series of HIV+ patients with AIDS who presented with cutaneous histoplasmosis and in whom the clinical and histopathological features were highly unusual, including variable mucocutaneous lesions that were difficult to diagnose clinically. These patients displayed unusual, previously undescribed, histological patterns, including lichenoid pattern, nodular pseudomyxoid pattern, pyogenic granuloma-like pattern, perifollicular pattern, and superficial (S), mid (M), and deep perivascular dermatitis; and more commonly encountered patterns, such as histiocytic lobular panniculitis and focal nodular dermatitis. The novel histopathological patterns of cutaneous involvement by histoplasmosis seen in these patients resembled other common inflammatory and infectious conditions and required a high level of suspicion and the application of special stains for organisms for confirmation. These new, clinical, and histological findings do not seem to be commonly encountered in HIV- patients infected with the fungus but seem to be displayed most prominently in HIV+ patients with AIDS.

Hepatic Kaposi Sarcoma Revisited: An Important but Less Commonly Seen Neoplasm in Patients With Acquired Immunodeficiency Syndrome.

Hepatic Kaposi sarcoma (KS) is the most commonly seen hepatic neoplasm in patients with acquired immunodeficiency syndrome (AIDS), found in 34% of patients in an autopsy series. However, the incidence of hepatic KS has significantly declined since the advent of highly active antiretroviral therapy and is not as commonly seen on imaging. We present a case of hepatic KS in a patient with AIDS, which was initially mistaken for hepatic abscesses on computed tomography. We discuss the computed tomography, grayscale ultrasound, and contrast-enhanced ultrasound appearance of hepatic KS and how to distinguish this hepatic neoplasm from other common hepatic lesions seen in patients with AIDS.

Although antiretroviral therapy has made human immunodeficiency virus (HIV) infection a controllable disease, it is still unclear how viral replication persists in untreated patients and causes CD4(+) T-cell depletion leading to acquired immunodeficiency syndrome (AIDS) in several years. Theorists tried to explain it with the diversity threshold theory in which accumulated mutations in the HIV genome make the virus so diverse that the immune system will no longer be able to recognize all the variants and fail to control the viraemia. Although the theory could apply to a number of cases, macaque AIDS models using simian immunodeficiency virus (SIV) have shown that failed viral control at the set point is not always associated with T-cell escape mutations. Moreover, even monkeys without a protective major histocompatibility complex (MHC) allele can contain replication of a super infected SIV following immunization with a live-attenuated SIV vaccine, while those animals are not capable of fighting primary SIV infection. Here we propose a recursion-based virus-specific naive CD4(+) T-cell depletion hypothesis through thinking on what may happen in individuals experiencing primary immunodeficiency virus infection. This could explain the mechanism for impairment of virus-specific immune response in the course of HIV infection. Copyright © 2016 Elsevier Ltd. All rights reserved.

In vivo treatment with interleukin 12 protects mice from immune abnormalities observed during murine acquired immunodeficiency syndrome (MAIDS)

PubMed Central

1994-01-01

Lymphoproliferation, chronic B cell activation resulting in hypergammaglobulinemia, and profound immunodeficiency are prominent features of a retrovirus-induced syndrome designated murine acquired immunodeficiency syndrome (MAIDS). In vivo treatment of infected mice with recombinant interleukin 12 (IL-12) beginning at the time of infection or up to 9 wk after virus inoculation markedly inhibited the development of splenomegaly and lymphadenopathy, as well as B cell activation and Ig secretion. Treatment with IL-12 also had major effects in preventing induction of several immune defects including impaired production of interferon gamma (IFN-gamma) and IL-2 and depressed proliferative responses to various stimuli. The therapeutic effects of IL-12 on the immune system of mice with MAIDS were also associated with reduced expression of the retrovirus that causes this disease (BM5def), with lesser effects on expression of ecotropic MuLV. IL-12 treatment was not effective in IFN-gamma knockout mice or in infected mice treated simultaneously with IL-12 and anti-IFN-gamma. These results demonstrate that induction and progression of MAIDS are antagonized by IL-12 through high-level expression of IFN-gamma and may provide an experimental basis for developing treatments of retrovirus- induced immune disorders with similar immunopathogenic mechanisms.

There is methodological debate as to whether cohorts defined by acquired immunodeficiency syndrome (AIDS) diagnosis can be used to estimate risks of cancer in persons with human immunodeficiency virus (HIV) before AIDS. The authors compared risks of non-AIDS-defining cancers before AIDS in persons with HIV using a cohort based on AIDS diagnosis and a second cohort based on HIV diagnosis. National population-based registries of AIDS and HIV diagnoses to August 1999 were matched separately with the National Cancer Registry in Australia. Four analyses were performed. In analysis 1, follow-up was from 5 years before AIDS registration in 8,118 persons with AIDS. Analysis 2 was similar but adjusted expected numbers of cancers for decreased survival. Analysis 3 was based on 7,061 persons registered with HIV, with follow-up from the reported date of diagnosis. Analysis 4 was based on 2,112 AIDS cases previously reported with HIV, with follow-up from 5 years before AIDS diagnosis. In all analyses, follow-up ended at cancer diagnosis, death, 6 months before AIDS, or the end of available cancer data, whichever occurred first. For 10 types of cancer there were at least three cases in any one of the analyses. For these cancers there was no systematic pattern such that one analysis produced consistently higher or lower estimates than the others. These analyses suggest that cancer risk in persons with HIV before AIDS diagnosis may be estimated reliably based on cancer experience 5 years before AIDS.

Epstein-Barr virus-associated primary central nervous system lymphoma in a child with the acquired immunodeficiency syndrome. A case report and review of the literature.

A 34-month-old black boy who had contracted acquired immunodeficiency syndrome from his mother presented with fever, vomiting, and cough. He was cachectic, hypertonic, and developmentally delayed. A brain computed tomography scan revealed masses in the left frontal horn, subependymal, and periventricular regions; secondary edema; and hydrocephalus. The differential diagnosis was cerebral lymphoma versus toxoplasmosis. The patient had disseminated Mycobacterium avium-intracellulare infection, lymphoid interstitial pneumonitis, as well as Pseudomonas and Klebsiella pneumonia. He died of respiratory insufficiency 53 days after admission. The autopsy confirmed a primary cerebral B-cell lymphoma, large cell type, which was positive for Epstein-Barr virus, latent phase, by in situ hybridization. Primary central nervous system lymphomas are rare in children, in contrast to adults. To our knowledge, only five well-documented cases of primary cerebral lymphomas in infants and children with acquired immunodeficiency syndrome have been reported previously. The current study shows that these childhood lymphomas are associated with and presumably caused by Epstein-Barr virus and thus have a pathogenesis similar to that of primary central nervous system lymphomas in adults.

Depression is a common co-morbidity among persons living with human immunodeficiency virus infection/acquired immunodeficiency syndrome (HIV/AIDS) (PLWHAs). It is associated with poor treatment adherence and higher mortality rates. Few reports have, however, emanated from developing countries where socioeconomic factors may confound this association. We conducted a cross-sectional comparative study of PLWHAs and apparently healthy staff of three LGA's. The depression module of the Schedule for the Clinical Assessment in Neuropsychiatry (SCAN) and the Beck Depression Inventory (BDI) was used to diagnose depression and depression symptom severity, respectively. Depression was commonly co-morbid among individuals with HIV/AIDS. It was five times more common in PLWHAs than in apparently healthy populations (29.3% vs. 7.3%, OR: 5.25, 95% CI: 2.50-11.76). A similar trend was observed for depression symptom severity. Among PLWHAs, depression was significantly more likely among females (OR: 7.91, 95% CI: 1.83-71.00, P < 0.01), those unemployed (OR: 2.94, 95% CI: 0.18-1.82, P < 0.04), and with an illness duration >3 years (OR: 7.90, P < 0.0001). Having at least one child (OR: 2.79, 95% CI: 1.25-6.16, P < 0.001) and living with others (OR: 4.71, 95% CI: 1.51-15.52, P < 0.003) significantly reduced depression risk. Depression was commonly co-morbid among PLWHAs studied. Clinicians should be aware of risk factors for depression among PLWHAs in order to improve treatment outcomes.

A 45-year-old man, a case of acquired immunodeficiency syndrome, received a highly active antiretroviral therapy at the outpatient service for 4 years without regular follow-up. He experienced progressively blurred vision for 6 months and a cutaneous zoster on his back 3 months ago. He was diagnosed with progressive outer retinal necrosis by polymerase chain reaction-restriction fragment length polymorphism using an aqueous humor sample, which revealed an existence of varicella zoster virus. He was given a combination of systemic, intravitreal antiviral and a highly active antiretroviral therapy. Occlusive vasculitis, an unusual finding for progressive outer retinal necrosis, developed in both eyes 1 week after the secondary intravitreal injection. Unfortunately, his vision deteriorated to no light perception in both eyes within 2 weeks. Progressive outer retinal necrosis is characterized clinically as showing minimal or no inflammation in the aqueous and vitreous humors, absence of retinal vasculitis, and patches of yellowish spots located deep in the retina. Physicians should pay attention to this rare case of progressive outer retinal necrosis associated occlusive vasculitis with very poor prognosis in spite of aggressive treatment. Copyright © 2015.

Women with acquired immune deficiency syndrome wasting are at an increased risk of osteopenia because of low weight, changes in body composition, and hormonal alterations. Although women comprise an increasing proportion of human immunodeficiency virus-infected patients, prior studies have not investigated bone loss in this expanding population of patients. In this study we investigated bone density, bone turnover, and hormonal parameters in 28 women with acquired immune deficiency syndrome wasting and relative androgen deficiency (defined as free testosterone < or =3.0 pg/ml, weight < or =90% ideal body weight, weight loss > or =10% from preillness maximum weight, or weight <100% ideal body weight with weight loss > or =5% from preillness maximum weight). Total body (1.04 +/- 0.08 vs. 1.10 +/- 0.07 g/cm2, human immunodeficiency virus-infected vs. control respectively; P < 0.01), anteroposterior lumbar spine (0.94 +/- 0.12 vs. 1.03 +/- 0.09 g/cm2; P = 0.005), lateral lumbar spine (0.71 +/- 0.14 vs. 0.79 +/- 0.09 g/cm2; P = 0.02), and hip (Ward's triangle; 0.68 +/- 0.14 vs. 0.76 +/- 0.12 g/cm2; P = 0.05) bone density were reduced in the human immunodeficiency virus-infected compared with control subjects. Serum N-telopeptide, a measure of bone resorption, was increased in human immunodeficiency virus-infected patients, compared with control subjects (14.6 +/- 5.8 vs. 11.3 +/- 3.8 nmol/liter bone collagen equivalents, human immunodeficiency virus-infected vs. control respectively; P = 0.03). Although body mass index was similar between the groups, muscle mass was significantly reduced in the human immunodeficiency virus-infected vs. control subjects (16 +/- 4 vs. 21 +/- 4 kg, human immunodeficiency virus-infected vs. control, respectively; P < 0.0001). In univariate regression analysis, muscle mass (r = 0.53; P = 0.004) and estrogen (r = 0.51; P = 0.008), but not free testosterone (r = -0.05, P = 0.81), were strongly associated with lumbar spine bone density in the

Genotypes of JC virus, DNA of cytomegalovirus, and proviral DNA of human immunodeficiency virus in eyes of acquired immunodeficiency syndrome patients.

JC virus (JCV) is a human polyomavirus that exists in at least eight different genotypes as a result of coevolution with different human populations all over the world. Well adapted to its host, it usually persists in the kidneys and possibly the brain. If the host becomes immunodeficient, JCV can cause the fatal demyelinating disease progressive multifocal leukoencephalopathy (PML). There is increasing evidence that JCV is transactivated by cytomegalovirus (CMV) and the human immunodeficiency virus (HIV). Both CMV and HIV can infect the retina of acquired immunodeficiency syndrome (AIDS) patients, causing severe necrosis in the case of CMV retinitis or a mild HIV-associated vasculopathy, with bleeding and cotton wool spots. The authors therefore investigated by polymerase chain reaction (PCR) whether DNA of these three viruses was detectable in paraffin-embedded eyes of AIDS patients with a clinical history of CMV retinitis. From a total of 65 eyes, JCV was detected in 21 (32%). Thirty-six (55%) were positive for CMV and 6 (9%) for proviral DNA of HIV. JCV and CMV were found in 13 eyes, JCV and HIV in 3 eyes, CMV and HIV in 1 eye, and DNA from all three viruses in 1 eye. The JCV genotypes were types 1A, 2A, 2E, 3, and 4. In 21 eyes of patients without AIDS, only one sample was JCV positive. In conclusion, JCV DNA can be detected in ocular tissue of AIDS patients at a significantly higher level than in eyes of nonimmunosuppressed patients. Further investigations will help to decide if JCV contributes to the retinopathy caused by CMV and HIV.

Identifying factors, which influence health behaviors is critical to designing appropriate and effective preventive programs. Human immunodeficiency virus (HIV) transmission is highly related to people behaviors and understanding factors influencing healthy behaviors among Iranian people living with HIVs (PLHIVs)/acquired immunodeficiency syndrome (AIDS) is very important to tailor an effective response to HIV/AIDS epidemic. This study was conducted as a qualitative study by methods of focus group discussion and in-depth interview in six provinces of Iran with 64 PLHIVs to determine factors influence engagement in positive prevention. Knowledge and education, feelings of responsibility and positive prevention practices were identified as the primary domains of engagement. These domains were found to be influenced by feelings of ostracism and frustration, poverty, barriers to disclosure of HIV status, access to and utilization of drug abuse treatment services and antiretroviral therapy, adherence to treatment, age, religiousness, sex work, singleness, and incarceration. Designing new interventions and updating current interventions directed toward the aforementioned factors should be addressed by responsible Iranian authorities in order to have a national effective response on the HIV/AIDS epidemic.

Antiretroviral adherence is the second strongest predictor of progression to acquired immunodeficiency syndrome (AIDS) and death, after CD4 count. Adherence to antiretroviral therapy (ART) has been strongly correlated with human immunodeficiency virus (HIV) viral suppression, reduced rates of resistance, an increase in survival, and improved quality of life. To determine the adherence rates and factors affecting adherence to ART among people living with HIV/AIDS (PLWHA). A Prospective study for 1 year was conducted among PLWHA, aged between 15 and 49 years, visiting ART center. 242 PLWHAs were included in the study. Structured questionnaire was used to obtain data on sociodemographic profile, factors affecting adherence. Adherence was assessed through self-reports, routine and random pill counts, and assessment of medical records. Descriptive statistics, logistic regression, and Chi-square tests were computed using Epi Info 7 version CDC (Centers for Disease Control and Prevention) U.S. Department of Health and Human Services. Adherence to ART was finally assessed on 242 PLWHAs. Mean age of subjects was 35 ± 7.8 years. One hundred percent adherence rate (consistent adherers) for the whole 6 month period was seen only in 31.6% patients. Lower 6 month averages of 95-100%, 80-95%, and <80% were noted in 49.8%, 9.1%, and 9.5% patients, thus resulting in optimal adherence rate of >95% in 81.4%. Earning member (odds ratio [OR] =0.404) and weight difference (OR = 0.818) were most associated with the adherent individuals. Most common psychological reason was forgetfulness in 44.9%. Adherence rate was poor among PLWHA and economic factors play an important role in adherence.

Pulmonary disease at autopsy in patients with the acquired immunodeficiency syndrome.

To characterize the postmortem pulmonary disease and analyze the effectiveness of antemortem diagnosis, we examined the clinical records and autopsy material from 54 patients who died of the acquired immunodeficiency syndrome. At autopsy, all patients had pulmonary disease. One or more specific diagnoses were made in 53, including opportunistic infection, nonopportunistic infection, and Kaposi's sarcoma. Multiple postmortem pulmonary diagnoses were established in 37. Respiratory failure was the most common cause of death. Of the 97 pulmonary disorders discovered at autopsy, only 31 were diagnosed before death. The frequency with which infections were diagnosed during life varied according to the organism, and was significantly higher for Pneumocystis carinii than for cytomegalovirus or bacterial agents. Pulmonary Kaposi's sarcoma was diagnosed in only 7% of patients with autopsy documentation. The yield of diagnostic procedures also varied according to the disease present. Sputum culture was relatively effective in detecting Cryptococcus neoformans and Mycobacterium avium-intracellulare, fiber-optic bronchoscopy was extremely useful for diagnosing P Carinii, and one or more diagnoses were provided in 4 of 7 patients who underwent thoracotomy, but significant disease including cytomegalovirus infection and pulmonary Kaposi's sarcoma was frequently missed. Although the spectrum of lung disease found at autopsy is similar to that observed during life, the frequency of some pathologic processes including cytomegalovirus infection and Kaposi's sarcoma may be underrepresented in antemortem series.

To investigate the features of oral lesions in patients with human immunodeficiency virus infection/acquired immunodeficiency syndrome (HIV/AIDS). A total of 127 HIV-seropositive patients were interviewed for health information and examined for their HIV-related oral lesions according to the EC Clearing House Criteria on Oral Problems related to HIV-Infection (1992). The examinations were conducted by dental specialist and HIV specialist. The CD4 T cell count in peripheral blood of the patients was tested by flow cytometry. The patients were divided into HIV- infected group (42) and AIDS group (85) according to CDC Classification System for HIV- Infected Adults and Adolescents (revised in 1993). Chi-square test was used to test the relationship between systemic disease and oral lesions, and the difference of the prevalence of oral lesions between the two groups. Among the 127 patients, oral candidiasis (51/127), oral hairy leukoplakia (24/127) were common oral manifestation. There was no relationship between the oral manifestation and systemic disease (P = 0.397). The occurrence of oral lesions and oral candidiasis was significantly different between the two groups (χ² = 7.684, P = 0.006; χ² = 14.410, P < 0.001). The CD4 count was related to the prevalence of oral lesions (P = 0.006) and oral candidasis (P = 0.003). Most oral lesions appeared before the appearance of systemic disease. Oral candidiasis and oral hairy leukoplakia were the most common lesions.Oral lesions had no relationship with systemic disease but could be still an indicator for disease progress.

Background: The purpose of the present study was to assess the existing level of knowledge of high school children about human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) and the sources of their information. Materials and Methods: A cross-sectional survey was conducted in two high schools in Kirikkale, Turkey and data were collected by a self-administered questionnaire. Multi-stage sampling technique was used to obtain a representative sample. Results: Four hundred and seventy three participants; 230 males and 243 females were analyzed. Their ages ranged from 15 to 19 years with a mean age of 16.81 ± 1.27. 92.2% of the students claimed to have heard about HIV/AIDS prior to the study with slightly more females than males. Although with some misconceptions, majority of the participants knew that HIV is not transmitted by sharing meals, casual contact, and sleeping in the same room and using the same bathroom. 93.4% identified HIV/AIDS as a life-threatening disease and 27% believe that there is a cure for AIDS. 64% and 22.8% respectively believed that the people can protect themselves by using condoms and by avoiding sexual contact. Internet was preponderantly claimed as the most important source of information about HIV/AIDS. Conclusion: Empirical evidence from this study suggests that the students have a fairly high knowledge of HIV/AIDS. This is not without some misconceptions about the prognosis of the disease. Internet was the major source of HIV/AIDS information. PMID:23633840

There is little detailed information on human immunodeficiency virus (HIV) amongst older adults in Singapore. A retrospective study of 121 consecutive referrals of patients presenting for HIV care was conducted. Demographic, clinical and laboratory variables were collected. A prognostic model derived from the North American Veterans' Affairs Cohort Study (VACS) was used to estimate prognosis. The median age at presentation was 43 (range, 18 to 76). Thirty-eight patients (31%) were aged 50 or older and 106 patients (88%) were male. Older patients were more likely to be of Chinese ethnicity (P = 0.035), married (P = 0.0001), unemployed or retired (P = 0.0001), and to have acquired their infection heterosexually (P = 0.0002). The majority of patients in both groups were symptomatic at presentation. Eighty-one (67%) had CD4 counts less than 200 at baseline with no observable differences in HIV ribonucleic acid (RNA) or clinical stage based on age. Non-Acquired Immunodeficiency Syndrome (AIDS) morbidity was observed more frequently amongst older patients. The estimated prognosis of patients differed significantly based on age. Using the VACS Index and comparing younger patients with those aged 50 and above, mean 5 year mortality estimates were 25% and 50% respectively (P <0.001). A trend towards earlier antiretroviral therapy was noted amongst older patients (P = 0.067) driven mainly by fewer financial difficulties reported as barriers to treatment. Older patients form a high proportion of newly diagnosed HIV/AIDS cases and present with more non-AIDS morbidity. This confers a poor prognosis despite comparable findings with younger patients in terms of clinical stage, AIDS-defining illness, CD4 count and HIV viral load.

Acquired immunodeficiency due to autoantibody against gamma interferon has recently been associated with opportunistic nontuberculous mycobacteriosis, especially among Southeast Asians. We report another 8 cases, all except one apparently immunocompetent hosts who suffered from concomitant or sequential infections by other intracellular pathogens causing penicilliosis, extraintestinal nontyphoidal salmonellosis, and burkholderiosis. The only case with an underlying immunodeficiency syndrome had systemic lupus erythematosus that was quiescent throughout the multiple infective episodes. Eight out of 10 (80.0%) patients with serological evidence of penicilliosis, 5 out of 7 (71.4%) with culture-positive extraintestinal nontyphoidal salmonellosis, 5 out of 28 (17.9%) with serological evidence of melioidosis, and 7 out of 13 (53.8%) with culture-positive nontuberculous mycobacteriosis possessed autoantibody against gamma interferon, whereas only 1 out of 100 patients with systemic lupus erythematosus did. Our study represents the first and largest case series linking this emerging immunodeficiency syndrome with these atypical infections in apparently immunocompetent hosts. Thus, we advocate that any patient with unexplained recurrent or polymicrobial infections due to these intracellular pathogens should be screened for acquired immunodeficiency due to autoantibody against gamma interferon.

Since the human immunodeficiency virus was identified as etiological agent of the acquired immunodeficiency syndrome, great advances have been accomplished in the therapeutic field leading to reduced morbidity and mortality among infected patients. However, the high mutation rate of the viral genome generates strains resistant to multiple drugs, pointing to the importance of finding new therapeutic targets. Among the HIV structural genes, the POL gene codes for three essential enzymes: reverse transcriptase, protease, and integrase; nineteen of the twenty drugs currently approved by the Food and Drug Administration to treat this viral infection, inhibit the reverse transcriptase and the protease. Although intense research has been carried out in this area during the last 10 years, HIV integrase inhibitors are not yet approved for clinical use; however the fact that presence of this enzyme is a sine qua non for a productive HIV life cycle joined to its unique properties makes it a promissory target for anti-HIV therapy. Many compounds have been claimed to inhibit integrase in vitro; however, few of them have proven to have antiviral activity and low cytotoxicity in cell systems. Diketoacid derivatives are the most promising integrase inhibitors so far reported. Initially discovered independently by Shionogi & Co. and the Merck Research Laboratories, these compounds are highly specific for the integrase with potent antiviral activity in vitro and in vivo, and low cytotoxicity in cell cultures. Some of these compounds have recently entered clinical trials. Due to the high relevance of integrase inhibitors, and specifically of diketoacid derivatives, we review the latest findings and patents in this important field of research.

In recent years there has been changes in the social and geographic profile of acquired immunodeficiency syndrome (AIDS). The aim of this study was to evaluate the internalization of AIDS in the state of Rondônia, Brazil. In Rondônia, 1473 AIDS cases were reported, with an average annual incidence of 15.8/100,000 persons (42.7 % women). The most common mode of viral transmission was sexual (96.5 %), and the majority of the individuals had not completed their primary education (64.8 %). There was heterogeneity in relation to case distribution, involving almost all of the municipalities in the state. The average annual mortality rate was 2.5/100,000 persons. Rondônia has a higher incidence of AIDS than the national average and the northern region. Efforts to provide access to treatment and follow-up of these individuals should be implemented, prioritizing areas where the incidence is higher and decentralizing the treatment of patients with AIDS in the state.

Individuals with acquired immunodeficiency syndrome (AIDS) manifest an increased risk of cancer, particularly cancers caused by oncogenic viruses. Because some salivary gland and nasopharyngeal cancers are associated with Epstein Barr virus, the impact of AIDS on these cancers needs further evaluation. We used linked U.S. AIDS and cancer registry data (N = 519,934 people with AIDS) to derive standardized incidence ratios (SIRs) comparing risk of salivary gland and nasopharyngeal cancers to the general population. For salivary gland cancers (N = 43 cases), individuals with AIDS had strongly elevated risks for lymphoepithelial carcinoma (SIR 39, 95% CI 16-81) and squamous cell carcinoma (SIR 4.9, 95% CI 2.5-8.6). Among nasopharyngeal cancers (N = 39 cases), risks were elevated for both keratinizing and nonkeratinizing carcinomas (SIR 2.4, 95% CI 1.5-3.7 and SIR 2.4, 95% CI 1.2-4.4, respectively). The elevated risks of salivary gland and nasopharyngeal cancers among people with AIDS suggest that immunosuppression and oncogenic viral infections are etiologically important.

To examine the role of vascular endothelial growth factor (VEGF) in the development of edema associated with Kaposi's sarcoma (KS) in acquired immunodeficiency syndrome (AIDS), we exploited animal model systems to detect the activity that induces vascular hyper‐permeability (VHP) using cultured AIDS‐KS spindle cells. Cultured AIDS‐KS spindle cells and conditioned medium (AIDS‐KS‐CM) that had been semi‐purified through a heparin affinity column were tested for the ability to induce VHP in animals. The AIDS‐KS spindle cells and AIDS‐KS‐CM induced VHP that was histamine‐independent. The VHP‐inducing activity was detected in the 0.5 M NaCl fraction from the heparin affinity column and was blocked by anti‐VEGF neutralizing antibody. In addition, the production of VEGF was demonstrated in fresh AIDS‐KS tissue as well as in cultured AIDS‐KS cells, while control cells were negative for VEGF production. From these observations, we concluded that AIDS‐KS cells produce a factor(s) that promotes VHP, and this factor could be VEGF. PMID:9045943

Individuals with acquired immunodeficiency syndrome (AIDS) manifest an increased risk of cancer, particularly cancers caused by oncogenic viruses. Because some salivary gland and nasopharyngeal cancers are associated with Epstein Barr virus, the impact of AIDS on these cancers needs further evaluation. We used linked U.S. AIDS and cancer registry data (N=519,934 people with AIDS) to derive standardized incidence ratios (SIRs) comparing risk of salivary gland and nasopharyngeal cancers to the general population. For salivary gland cancers (N=43 cases), individuals with AIDS had strongly elevated risks for lymphoepithelial carcinoma (SIR 39, 95% CI 16-81) and squamous cell carcinoma (SIR 4.9, 95% CI 2.5-8.6).

Cytokine activity and polymorphisms have been associated with sleep outcomes in prior animal and human research. The purpose of this study was to determine whether circulating plasma cytokines and cytokine polymorphisms are associated with the poor sleep maintenance commonly experienced by adults living with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS). Cross-sectional descriptive study. HIV clinics and community sites in the San Francisco Bay area. A convenience sample of 289 adults (193 men, 73 women, and 23 transgender) living with HIV/AIDS. None. A wrist actigraph was worn for 72 h to estimate the percentage of wake after sleep onset (WASO%) and total sleep time (TST), plasma cytokines were analyzed, and genotyping was conducted for 15 candidate genes involved in cytokine signaling: interferon-gamma (IFNG), IFNG receptor 1 (IFNGR1), interleukins (IL1B, IL1R2, IL1R2, IL2, IL4, IL6, IL8, IL10, IL13, IL17A), nuclear factor of kappa light polypeptide gene enhancer in B cells (NFKB1 and NFKB2), and tumor necrosis factor-alpha (TNFA). Controlling for demographic variables such as race and sex, and clinical variables such as CD4+ count and medications, higher WASO% was associated with single nucleotide polymorphisms (SNPs) of IL1R2 rs11674595 and TNFA rs1041981 and less WASO% was associated with IL2 rs2069776. IL1R2 rs11674595 and TNFA rs1041981 were also associated with short sleep duration. This study strengthens the evidence for an association between inflammation and sleep maintenance problems. In this chronic illness population, cytokine polymorphisms associated with wake after sleep onset provide direction for intervention research aimed at comparing anti-inflammatory mechanisms with hypnotic agents for improving sleep maintenance and total sleep time.

To evaluate the prevalence of intermediate-stage age-related macular degeneration (AMD) in patients with acquired immunodeficiency syndrome (AIDS). Cross-sectional study of patients with AIDS enrolled in the Longitudinal Study of the Ocular Complications of AIDS. Intermediate-stage AMD was determined from enrollment retinal photographs by graders at a centralized Reading Center, using the Age-Related Eye Disease Study grading system. Graders were masked as to clinical data. Of 1825 participants with AIDS and no ocular opportunistic infections, 9.9% had intermediate-stage AMD. Risk factors included age, with an odds ratio (OR) of 1.9 (95% confidence interval [CI] 1.6, 2.3, P < .001) for every decade of age; the prevalence of AMD ranged from 4.0% for participants 30-39 years old to 24.3% for participants ≥60 years old. Other risk factors included the human immunodeficiency virus (HIV) risk groups of injection drug use (OR = 2.4, 95% CI 1.5, 3.9, P < .001) or heterosexual contact (OR = 1.9, 95% CI 1.3, 2.8, P = .001). Compared with the HIV-uninfected population in the Beaver Dam Offspring Study, there was an approximate 4-fold increased age-adjusted prevalence of intermediate-stage AMD. Patients with AIDS have an increased age-adjusted prevalence of intermediate-stage AMD compared with that found in a non-HIV-infected cohort evaluated with similar methods. This increased prevalence is consistent with the increased prevalence of other age-related diseases in antiretroviral-treated, immune-restored, HIV-infected persons when compared to non-HIV-infected persons.

Duvic, M; Lowe, L; Rapini, R P; Rodriguez, S; Levy, M L

1989-03-01

The cutaneous manifestations of the acquired immunodeficiency syndrome include infections and neoplasms resulting from the immunodeficient state. Seven patients presenting with the symptom of new eruptive nevi with dysplastic histologic findings are described. These patients noted multiple new moles, which occurred in crops and in individuals without the dysplastic nevus syndrome (familial melanomas). This symptom occurred as the patients became symptomatic from their human immunodeficiency virus infection, developing acquired immunodeficiency syndrome or its related complex. Further confirmation and study of this phenomenon could lead to a better understanding of the pathogenesis of melanocytic dysplasia and its relationship to the immune system.

Kaposi sarcoma (KS) is a vascular tumor frequently associated with advanced human immunodeficiency virus infection, advanced age, or iatrogenic immunosuppression. Immunohistochemistry for CD31 and CD34, and more recently for FLI1 and D2-40, has been used as ancillary diagnostic tests for KS, despite little information regarding the sensitivities and differential staining patterns of the latter 2 markers in the major clinical subtypes and histologic stages of KS. This retrospective study aims to assess the prevalence of the vascular markers D2-40 and FLI1 in the main clinical subgroups and tumor stages of KS. Twenty-four cases of KS (12 acquired immunodeficiency syndrome [AIDS]-related cases and 12 non-AIDS-related cases; 11 nodular-stage and 13 patch/plaque-stage KS) were stained for CD34, CD31, D2-40, and FLI1 by immunohistochemistry. The distribution of immunoreactivity was compared between the clinical subtypes and tumor stages of KS using the Mann-Whitney test. CD31, CD34, D2-40, and FLI1 strongly and diffusely stained tumor cells in 75%, 92%, 67%, and 92% of AIDS-related cases and 58%, 92%, 67%, and 75% of non-AIDS-related cases, respectively. Differences in the proportions of positive cases between AIDS-related and non-AIDS-related cases did not reach statistical significance. No significant staining differences were observed between nodular- and patch/plaque-stage KS either. There are no differences in the distribution of immunohistochemical reactivity for CD31, CD34, D2-40, or FLI1 between AIDS-related and non-AIDS-related KS or between nodular- and patch/plaque-stage KS. All of the markers studied demonstrated high sensitivity in both clinical settings and both stages of tumor progression.

1988-01-01

The present study was performed to develop a serological method for diagnosing toxoplasmic encephalitis in patients with acquired immunodeficiency syndrome (AIDS). The trophozoite form of Toxoplasma gondii, fixed with either Formalin or acetone, was used in a modification of an agglutination method previously shown to differentiate between the acute and the chronic (latent) stages of infection with toxoplasma in immunologically normal persons. By using these antigens in separate tests and evaluating the data for statistical significance, 70% of patients with AIDS with biopsy-proven toxoplasmic encephalitis were distinguished from control, ambulatory patients with AIDS with toxoplasma antibodies but without signs or symptoms of central nervous system involvement. In a separate study, the agglutination tests identified from controls 84% of patients with AIDS with two or more brain lesions detected by computed-tomographic or magnetic-resonance-imaging scans and suspected of having toxoplasmic encephalitis. Thus, these agglutination tests should prove valuable for the noninvasive diagnosis of toxoplasmic encephalitis in patients with AIDS. PMID:3230132

Stigma has been implicated in poor outcomes of human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) care. Reducing stigma is important for HIV prevention and long-term treatment success. Although stigma reduction interventions are conducted in Mozambique, little is known about the current nature of stigma and the efficacy and effectiveness of stigma reduction initiatives. We describe action research to generate consensus on critical characteristics of HIV stigma and anti-stigma interventions in Zambézia Province, Mozambique. Qualitative data gathering methods, including indepth key-informant interviews, community interviews and consensus group sessions, were utilized. Delphi methods and the strategic options development analysis technique were used to synthesize qualitative data. Key findings are that stigma enacted by the general public might be declining in tandem with the HIV/AIDS epidemic in Mozambique, but there is likely excessive residual fear of HIV disease and community attitudes that sustain high levels of perceived stigma. HIV-positive women accessing maternal and child health services appear to shoulder a disproportionate burden of stigma. Unintentional biases among healthcare providers are currently the critical frontier of stigmatization, but there are few interventions designed to address them. Culturally sensitive psychotherapies are needed to address psychological distress associated with internalized stigma and these interventions should complement current supports for voluntary counseling and testing. While advantageous for defining stakeholder priorities for stigma reduction efforts, confirmatory quantitative studies of these consensus positions are needed before the launch of specific interventions.

To investigate whether human immunodeficiency virus (HIV) infection or its treatment is a risk factor for thyroid dysfunction and whether thyroid function changes over time in 2 distinct subpopulations with HIV or acquired immunodeficiency syndrome (AIDS) in Israel: Ethiopian immigrants and Israeli patients. Serum thyroid-stimulating hormone (TSH) and free thyroxine levels were determined in HIV carriers undergoing follow-up at the Hadassah-Hebrew University Medical Center HIV clinic in Jerusalem, Israel, and these thyroid measurements were correlated with clinical and laboratory variables pertaining to their disease, including disease duration, drug therapy, viral load, CD4 count, low-density lipoprotein cholesterol, and creatine kinase. Serum samples stored at -20°C from the time of referral were tested as well. We recruited 121 consecutive patients with HIV or AIDS for this study: 60 Ethiopians and 61 Israeli patients. Of the 121 patients, 4 (3%) had abnormal thyroid function-subclinical hypothyroidism in 2, overt hypothyroidism in 1, and overt hyperthyroidism in 1. Previously stored serum samples were available for 60 of the 121 patients and revealed 2 additional patients with subclinical hypothyroidism, whose TSH has normalized in the subsequent test. Throughout the follow-up period of 3.2 ± 1.9 years, the mean TSH level remained unchanged in the Israeli cohort but significantly declined in the Ethiopian cohort. Thyroid function abnormalities were uncommon in these Israeli patients with HIV or AIDS. This finding does not support the need for routine thyroid function tests in this patient population. The decline in TSH level in the Ethiopian population over time probably represents a shift from an iodine-deficient to an iodine-sufficient country.

The number of patients living with human immunodeficiency virus and acquired immunodeficiency syndrome is growing due to advances in antiretroviral therapy. Existing literature on appendectomy within this patient population has been limited by small sample sizes. Therefore, we used a large, multiyear, nationwide database to study this topic comprehensively. Using the Nationwide Inpatient Sample, we identified 338,805 patients between 2005 and 2012 who underwent laparoscopic or open appendectomy for acute appendicitis. Interval appendectomies were excluded. We used multivariable adjusted regression models to test differences between patients with human immunodeficiency virus without acquired immunodeficiency syndrome and a reference group, as well as human immunodeficiency virus with acquired immunodeficiency syndrome and a reference group, with regard to duration of stay, hospital charges, in-hospital complications, and in-hospital mortality. Models were adjusted for patient age, sex, race, insurance, socioeconomic status, Elixhauser comorbidity score, and appendix perforation. There were 1,291 (0.38%) patients with human immunodeficiency virus, among which 497 (0.15%) patients had acquired immunodeficiency syndrome. In regression analysis, human immunodeficiency virus alone was not associated with adverse outcomes, while acquired immunodeficiency syndrome alone was associated with longer duration of stay (incidence rate ratio 1.40 [1.37-1.57 95% confidence interval], P < .0001), increased total charges (exponentiated coefficient 1.16 [1.10-1.23 95% confidence interval], P < .0001), and increased risk of postoperative infection (odds ratio 2.12 [1.44-3.13 95% confidence interval], P = .0002). Patients with acquired immunodeficiency syndrome who undergo appendectomy for acute appendicitis are subject to longer and more expensive hospital admissions and have greater rates of postoperative infections while patients with human immunodeficiency virus alone are not

To assess the incidence of oral candidiasis and its influencing factors in patients with human immunodeficiency virus infection/acquired immunodeficiency syndrome (HIV/AIDS). An oral examination was conducted in the 1 566 HIV/AIDS patients in the Third Hospital of Kunming from March 2008 to September 2012 (M/F: 1 062/504, age range: 0.2 to 84.0 years old). The HIV viral load (HIV- RNA) and peripheral blood CD4 count were respectively analyzed by Bayer Q340 fluorescence signal surveying instrument (bDNA method) and flow cytometry analysis. The information on usage of highly active anti-retroviral (HAART) drugs and transmission of HIV were obtained through questionnaires. The incidence of oral candidiasis in patients with different HIV-RNA levels and CD4 count and the use of HAART was analyzed and compared. The total incidence of oral candidosis was 31.0% (486/1 566) and there was no difference in sex. The oral lesions were presented by three types, psudomembranous candidosis (PC), erythematous candidosis (EC) and angular cheilitis (AC), and the morbidity was 13.9% (217/1 566), 17.0% (267/1 566) and 4.9% (77/1 566), respectively. The average level of CD4 count in psudomembranous candidosis, erythematous candidosis and angular cheilitis [81.0 (146.0), 74.0 (152.0) and 69.0 (121.5) cell/µl] showed no significant difference (P > 0.05). The incidence of oral candidiasis in non-HAART and HAART subjects were 36.3% (402/1 107) and 18.3% (84/459), respectively (P = 0.000). The CD4 count and absolute counts of HIV viral load in oral candidiasis patients and non-oral candidiasis patients had significant difference (Z = -10.261, P = 0.000 and Z = -4.762, P = 0.000). The morbidity of oral candidiasis in HIV/AIDS patients in Yunnan Province was high, including PC, EC and AC and hyperplastic candidosis was not detected. The incidence was related to the degree of immune suppression and HIV viral load.

To evaluate the incidence of intermediate-stage age-related macular degeneration (AMD) in patients with acquired immunodeficiency syndrome (AIDS). Cohort study. Patients enrolled in the Longitudinal Study of the Ocular Complications of AIDS (LSOCA) underwent 5- and 10-year follow-up retinal photographs. Intermediate-stage AMD (AREDS stage 3) was determined from these photographs by graders at a centralized Reading Center, using the Age-Related Eye Disease Study-2 grading system. The incidence of AMD in LSOCA was compared with that in the Multi-Ethnic Study of Atherosclerosis (MESA), a Human Immunodeficiency Virus (HIV)-uninfected cohort, which used a similar photographic methodology. The incidence of AMD in LSOCA was 0.65/100 person-years (PY). In a multivariate analysis the only significant risk factor for AMD in LSOCA was smoking; the relative risk vs never-smokers was 3.4 for former smokers (95% confidence interval [CI] 1.3, 9.5; P = .02) and 3.3 for current smokers (95% CI 1.1, 9.7; P = .03). Compared with the MESA cohort, the race/ethnicity- and sex-adjusted risk of AMD in LSOCA was 1.75 (95% CI 1.16, 2.64; P = .008), despite the fact that the mean age of the MESA cohort was 17 years greater than the LSOCA cohort (61 ± 9 years vs 44 ± 8 years). Patients with AIDS have a 1.75-fold increased race- and sex-adjusted incidence of intermediate-stage AMD compared with that found in an HIV-uninfected cohort. This increased incidence is consistent with the increased incidence of other age-related diseases in antiretroviral-treated, immune-restored, HIV-infected persons when compared with HIV-uninfected persons.

Because human inmmunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) receives more donor funding globally than that for all other diseases combined, some critics allege this support undermines general health care. This empirical study evaluates the impact of HIV/AIDS funding on the primary health care system in Rwanda. Using a quasi-experimental design, we randomly selected 25 rural health centers (HCs) that started comprehensive HIV/AIDS services from 2002 through 2006 as the intervention group. Matched HCs with no HIV/AIDS services formed the control group. The analysis compared growth in inputs and services between intervention and control HCs with a difference-in-difference analysis in a random-effects model. Intervention HCs performed better than control HCs in most services (seven of nine), although only one of these improvements (Bacille Calmette-Guérin vaccination) reached or approached statistical significance. In conclusion, this six-year controlled study found no adverse effects of the expansion of HIV/AIDS services on non-HIV services among rural health centers in Rwanda. PMID:22556094

Infections of the central nervous system (CNS) in individuals with human immunodeficiency virus (HIV) remain a substantial cause of morbidity and mortality despite the introduction of highly active antiretroviral therapy (HAART) especially in the resource-limited regions of the world. Diagnosis of these infections may be challenging because findings on cerebrospinal fluid (CSF) analysis and brain imaging are nonspecific. While brain biopsy provides a definitive diagnosis, it is an invasive procedure associated with a relatively low mortality rate, thus less invasive modalities have been studied in recent years. Diagnosis, therefore, can be established based on a combination of a compatible clinical syndrome, radiologic and CSF findings, and understanding of the role of HIV in these infections. The most common CNS opportunistic infections are AIDS-defining conditions; thus, treatment of these infections in combination with HAART has greatly improved survival.

Hypothalamic-pituitary dysfunction and thyroid gland cytomegalovirus inclusions have been described in patients with the acquired immunodeficiency syndrome (AIDS) and AIDS-related complex (ARC). We evaluated 80 patients with AIDS or ARC for the frequency of hypothalamic-pituitary or thyroid gland failure and altered serum thyroid hormone levels due to nonthyroidal disorders. One patient had subclinical hypothyroidism. Of these patients, 60% had low free triiodothyronine (T3) index values and 4% had low free thyroxine (T4) indexes; none of the latter had hypothalamic-pituitary or thyroid gland failure, since all serum cortisol values were greater than or equal to 552 nmol per liter (greater than or equal to 20 micrograms per dl) and all thyrotropin levels were less than or equal to 3 mU per liter (less than or equal to 3 microU per ml), respectively. Those who died had lower total T4 and T3, free T3 index, and albumin levels than those discharged from hospital. Serum total T4 and T3 levels correlated with albumin levels and total T3 with serum sodium levels. Serum total T3 levels best predicted the outcome of the hospital stay (accuracy = 82%). Thus, abnormal serum thyroid hormone levels in AIDS or ARC patients are most frequently due to nonthyroidal disorders, but hypothalamic-pituitary or thyroid gland failure may occur. PMID:2618039

Cytomegalovirus (CMV) retinitis remains the most common ocular opportunistic infection in patients with acquired immunodeficiency syndrome even in the era of highly active antiretroviral therapy (HAART). Increased survival of patients on HAART has increased incidence of blindness, which will further increase in the future. The objective of this study was to determine the incidence of CMV retinitis and the effect of HAART on the natural history of CMV retinitis in patients referred from ART center. Patients with baseline/current CD4 counts <150 cells/µl were evaluated for CMV retinitis. Complete ophthalmological evaluation was carried out and records of CD4 counts, HAART regime, presence of any form of CMV retinitis and response to HAART were noted. Out of 800 patients registered with CD4 <150 cells/µl in ART center, 100 patients reached us. Among these, CMV retinitis was observed in 15% patients, with median CD4 count at the time of examination being 56 cells/µl (range: 24-306 cells/µl). 66.67% patients were HAART non-responders and 63.6% eyes were economically blind. CMV retinitis occurs even in patients with higher CD4 counts. Timely diagnosis and intervention of this treatable condition can reduce the number of blinding years in these young patients who otherwise live longer as a result of HAART.

The association of disseminated magnesium silicate talc granulomatosis and acquired immunodeficiency syndrome is reported in a male homosexual who used intravenous drugs and who died of overwhelming cytomegalovirus (CMV) infection. Autopsy findings included widespread deposition of talc crystals in the lungs, liver, lymph nodes, bone marrow, and spleen. Typical CMV inclusions were seen in the lungs, kidneys, adrenal glands, gastrointestinal tract, and right eye. There was no evidence of malignancy. Analysis of peripheral blood neutrophil function revealed impaired chemotaxis and chemokinesis, but opsonophagocytosis had remained normal. The CMV infection in the small bowel was extensive and resulted in severe destruction of the muscularis propria and neural plexi, leading to marked dilatation and persistent diarrhea. The terminal course was marked by intractable hypotension, pneumonitis, and malnutrition, which could be attributed respectively to CMV involvement of the adrenal glands, lungs, and small bowel. The etiology and possible role of systemic talc granulomatosis in the development of immunosuppressive illness is reported herein.

Between 6000 and 7000 women in the United States infected with human immunodeficiency virus (HIV) give birth annually. It is well known that HIV-related immunosuppression significantly increases the risk for acquiring opportunistic infections (OIs). However, there is limited information regarding the relationship of pregnancy in the setting of HIV/AIDS infection, subsequent development of OIs, and maternal and fetal outcomes. A pregnant 36-year-old woman with AIDS was diagnosed with varicella zoster meningitis. Weight-based therapy with acyclovir was initiated with clinical improvement in symptoms. Care of a pregnant HIV-infected patient with an OI poses a unique diagnostic and therapeutic challenge for clinicians. Early diagnosis and initiation of appropriate treatment may provide an opportunity to improve both maternal and fetal outcomes.

Introduction Plasmablastic lymphoma is a rare entity that was first described in the jaws and the oral cavity of patients with human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS). Plasmablastic lymphoma is considered as a diffuse, large, B-cell lymphoma with a unique phenotype and a predilection for the oral cavity. Objective The authors describe a case of an aggressive plasmablastic lymphoma of the oral cavity as the primary manifestation of AIDS. Resumed Report We report a case of plasmablastic lymphoma involving only the oral cavity as the first manifestation of AIDS. Diagnosis was confirmed by the oral lesion biopsy and the histopathologic examination that showed a dense infiltrate composed of atypical lymphocytes with numerous plasmocytes that expressed the plasma cell markers MUM-1 and CD138 and that were negative for the B-cell markers CD3, CD20, and CD45. Immunohistochemical and in situ hybridization revealed the Epstein-Barr virus genome in the atypical cells. Polymerase chain reaction was also positive for human herpesvirus-8 RNA. Conclusion The HIV serologic status should be evaluated in all patients with plasmablastic lymphoma of the oral cavity or extraoral sites. PMID:26491484

To investigate the distribution of abnormal hilit syndromes in traditional Uighur medicine (TUM) among human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) patients, and to find out the clinical characteristics of abnormal savda syndrome type HIV/AIDS patients. Between June and July in 2012, 307 eligible HIV/AIDS patients from in-patient department and out-patient clinics of Xinjiang Uighur Autonomous Region the Sixth People's Hospital in Urumqi were investigated. TUM syndrome differentiation was performed by a senior TUM physician. Each participant completed a Sign and Symptom Check-List for Persons Living with HIV/AIDS (SSC-HIV) questionnaire. Depression was evaluated by using Hamilton Rating Scale for Depression Questionnaire. Blood specimen was collected from each participant to test the levels of blood chemicals. Of 307 HIV/AIDS patients, 189 (61.6%) were abnormal savda syndrome type, 118 (38.4%) were non-abnormal-savda syndrome type. Mean CD4 counts of abnormal savda syndrome type patients was (227.61±192.93) cells/µL, and the prevalence of anemia, thrombocytopenia, and elevated cystatin C were 49.7%, 28.6%, and 44.7%, which were significantly higher than those in the non-abnormal-savda syndrome type patients (26.3%, 16.0% and 25.0%,P<0.05). In addition, depression (79.9%) and HIV/AIDS-related symptoms such as fatigue (42.3%), back aches (40.7%), lack of appetite (33.9%), night sweats (31.7%) were more common among abnormal savda syndrome patients (P<0.05). Abnormal savda syndrome is the dominant syndrome among HIV/AIDS patients, and they present a more sever clinical manifestation.

To understand recent temporal trends in acquired immunodeficiency syndrome (AIDS) mortality in the era of highly active antiretroviral therapy (HAART), trends in causes of death among persons with AIDS in San Francisco who died between 1994 and 1998 were analyzed. Among 5234 deaths, the mortality rate for human immunodeficiency virus (HIV)-related or AIDS-related deaths declined after 1995 (P<.01), whereas the mortality rate for non-HIV- or non-AIDS-related deaths remained stable. The proportion of deaths of persons with AIDS associated with septicemia, non-AIDS-defining malignancy, chronic liver disease, viral hepatitis, overdose, obstructive lung disease, coronary artery disease, and pancreatitis increased (P<.05). The standardized mortality ratio was high for these causes in both pre- and post-HAART periods, except for pancreatitis, a possible complication of HAART, which demonstrated an increasing standardized mortality ratio trend after 1996. With increasing AIDS survival, prevention of chronic diseases, assessment of long-term toxicity from HAART, and surveillance for additional causes of mortality will become increasingly important.

Low incidence of human immunodeficiency virus (HIV) infections and acquired immunodeficiency syndrome (AIDS) has been detected in Croatia so far. Toxoplasmic encephalitis (TE) is the most common opportunistic cerebral infection in AIDS patients and is highly responsive to antiparasitic chemotherapy, if treated at an early stage. We present the case of the brain biopsy confirmed as TE on a 36-year-old female patient who at admission presented with unconsciousness and a right hemiplegia. A MSCT was performed and two hypodense lesions were diagnosed. The patient's family initially denied the presence or history of any medical problem or infection. An MRI showed multiple ring-enhanced mass lesions. An infectologist required a brain biopsy to exclude cerebral lymphoma and multiple metastases. Pathohistological analysis suggested TE. Meanwhile, patient's blood samples were found to be HIV positive. The patient was transferred to University Hospital for Infectious Diseases in Zagreb, where she died 2 days following admission. The patient's family terminally confessed that the patient had been HIV positive for 10 years and had refused any treatment. Family's denial of infection as well as 'hiding information' concerning patient's health from physicians involved in her treatment caused a delay in proper on-time patient treatment. We would like to emphasize that TE must be considered as a differential diagnosis in patients presenting with multiple cerebral lesions, including patients without acknowledged past history of HIV infection. A stigma towards HIV infection and ignorance of the disease still exist and therefore hinders proper treatment.

A T-cell tropic retrovirus, simian immunodeficiency virus (SIV), has recently been isolated from immunodeficient rhesus monkeys. This virus has remarkable similarities to human immunodeficiency virus (HIV), the etiologic agent of acquired immunodeficiency syndrome. Subsequent studies of simian infection with SIV have shown it to be a relevant animal model for studying the pathogenesis of AIDS in man. In both HIV-infected humans and SIV-infected monkeys, a cutaneous maculopapular eruption has been described. To date, the pathogenesis and possible relationship of these exanthema to the evolution of systemic immunosuppression have remained obscure. In this study, the mononuclear cell infiltrates that characterize skin rashes of SIV-infected rhesus monkeys were found to be composed predominantly of cells with phenotypic characteristics of cytotoxic/suppressor (T8+) lymphocytes and natural killer cells. Many of these cells expressed membrane-bound interleukin-2 receptor molecules. Double labeling and immunoelectron microscopy revealed these cells in direct contact with degenerative Langerhans cells within the epidermis and dermis. These observations suggest that the cutaneous rash associated with SIV infection may be the consequence of target cell injury of Langerhans cells by effector cells with cytotoxic potential.

To report the incidence and clinical outcomes of non-cytomegalovirus (non-CMV) ocular opportunistic infections in patients with acquired immunodeficiency syndrome (AIDS) in the era of highly active antiretroviral therapy. Multicenter, prospective, observational study of patients with AIDS. Medical history, ophthalmologic examination, and laboratory tests were performed at enrollment and every 6 months subsequently. Once an ocular opportunistic infection was diagnosed, patients were seen every 3 months for outcomes. At enrollment, 37 non-CMV ocular opportunistic infections were diagnosed: 16 patients, herpetic retinitis; 11 patients, toxoplasmic retinitis; and 10 patients, choroiditis. During the follow-up period, the estimated incidences (and 95% confidence intervals [CI]) of these were: herpetic retinitis, 0.007/100 person-years (PY) (95% CI 0.0004, 0.039); toxoplasmic retinitis, 0.007/100 PY (95% CI 0.004, 0.039); and choroiditis, 0.014/ 100 PY (95% CI 0.0025, 0.050). The mortality rates appeared higher among those patients with newly diagnosed or incident herpetic retinitis and choroiditis (rates = 21.7 deaths/100 PY [P = .02] and 12.8 deaths/100 PY [P = .04]), respectively, than those for patients with AIDS without an ocular opportunistic infection (4.1 deaths/100 PY); toxoplasmic retinitis did not appear to be associated with greater mortality (6.4/100 PY, P = .47). Eyes with newly diagnosed herpetic retinitis appeared to have a poor visual prognosis, with high rates of visual impairment (37.9/100 PY) and blindness (17.5/100 PY), whereas those outcomes in eyes with choroiditis appeared to be lower (2.3/100 PY and 0/100 PY, respectively). Although uncommon, non-CMV ocular opportunistic infections may be associated with high rates of visual loss and/or mortality. Copyright © 2013 Elsevier Inc. All rights reserved.

Although discontinuation of suppressive antifungal therapy for acquired immunodeficiency syndrome (AIDS)-associated histoplasmosis is accepted for patients with immunologic recovery, there have been no published studies of this approach in clinical practice, and minimal characterization of individuals who relapse with this disease. We performed a multicenter retrospective cohort study to determine the outcome in AIDS patients following discontinuation of suppressive antifungal therapy for histoplasmosis. Ninety-seven patients were divided into a physician-discontinued suppressive therapy group (PD) (38 patients) and a physician-continued suppressive therapy group (PC) (59 patients). The 2 groups were not statistically different at baseline, but at discontinuation of therapy and at the most recent follow-up there were significant differences in adherence to therapy, human immunodeficiency virus (HIV) RNA, and urinary Histoplasma antigen concentration. There was no relapse or death attributed to histoplasmosis in the PD group compared with 36% relapse (p < 0.0001) and 5% death (p = 0.28) in the PC group. Relapse occurred in 53% of the nonadherent patients but not in the adherent patients (p < 0.0001). Sixty-seven percent of patients with initial central nervous system (CNS) histoplasmosis relapsed compared to 15% of patients without CNS involvement (p = 0.0004), which may be accounted for by nonadherence. In addition, patients with antigenuria above 2.0 ng/mL at 1-year follow-up were 12.82 times (95% confidence interval, 2.91-55.56) more likely to relapse compared to those with antigenuria below 2.0 ng/mL. Discontinuation of antifungal therapy was safe in adherent patients who completed at least 1 year of antifungal treatment, and had CD4 counts >150 cells/mL, HIV RNA <400 c/mL, Histoplasma antigenuria <2 ng/mL (equivalent to <4.0 units in second-generation method), and no CNS histoplasmosis.

BACKGROUND Hepatocellular carcinoma (HCC) is a concern among individuals with human immunodeficiency virus (HIV) infection and acquired immunodeficiency syndrome (AIDS). METHODS The authors analyzed population-based registry linkage data from the US HIV/AIDS Cancer Match Study (1980–2009) to examine the risk and trends of HCC among individuals with AIDS. Standardized incidence ratios (SIRs) were used to measure HCC risk relative to the general population, and Poisson regression was used to calculate incidence rate ratios (RR) comparing incidence among individuals with AIDS. People with AIDS were categorized according to their HIV risk group into high and low hepatitis C virus (HCV) prevalence groups based on their HIV transmission risk category. RESULTS Among 615,150 individuals with AIDS, HCC risk was elevated almost 4 times compared with the risk in the general population (N = 366; SIR, 3.8; 95% confidence interval, 3.5–4.3). Although HCC incidence increased steadily across calendar periods (Ptrend < .0001; adjusted for sex and age), the excess risk in individuals with AIDS compared with the general population remained somewhat constant (SIRs range, 3.5–3.9) between the monotherapy/dual therapy era (1990–1995) and the recent highly active antiretroviral therapy era (2001–2009). In a multivariate model adjusting for sex, race/ethnicity, and attained calendar period, HCC incidence increased with advancing age (Ptrend < .0001) and was associated with HIV risk groups with a known higher prevalence of HCV (adjusted RR, 2.2; 95% confidence interval, 1.8–2.8). CONCLUSIONS HCC incidence in individuals with AIDS has increased over time despite improved HIV treatment regimens, likely reflecting prolonged survival with chronic liver disease. The high incidence in older adults suggests that this cancer will increase in importance with aging of the HIV-infected population. PMID:22736272

Mucocutaneous lesions occur at one point or the other during the course of human immunodeficiency virus (HIV) disease. These lesions can be the initial presenting features but could also be a pointer to the presence of immunosuppression. This study was carried out to determine the pattern of mucocutaneous manifestation in children who have human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) in relation to their level of immunosuppression. One hundred children who were HIV seropositive aged 18months to 16years were evaluated for mucocutaneous lesions, and their degree of immunosuppression was also determined using total CD(4+) count or CD(4+) percentage. Another group of age and gender matched 100 HIV-negative children were also examined for mucocutaneous lesions. The mucocutaneous manifestations were more common among the subjects compared to controls (P=0.000). The overall prevalence among the seropositive and seronegative subjects was 64% and 12% respectively. The prevalence of mucocutaneous findings in children with severe, moderate, and no immunosuppression were 93.8%, 55.2%, and 46.2%, respectively. The lesions were significantly more common among those with moderate and severe immunosuppression compared to those with no immunosuppression (P=0.000). Multiple lesions were more frequent among those with severe immunosuppression. Oral thrush was the most frequent lesion (25.6%) among the subjects followed by pruritic papular eruption (20.7%) and dermatophytosis (14.1%). Severe and atypical forms of dermatophytosis and herpes ulcer were also observed among the subjects. This study shows that mucocutaneous lesions are common in children with HIV/AIDS and could be an early indicator of immune suppression. It is important to recognize them early in order to enhance early case detection and treatment. © 2012 The International Society of Dermatology.

Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome in Older Adults.

Scott, Jake; Goetz, Matthew Bidwell

2016-08-01

Improved survival with combination antiretroviral therapy has led to a dramatic increase in the number of human immunodeficiency virus (HIV)-infected individuals 50 years of age or older such that by 2020 more than 50% of HIV-infected persons in the United States will be above this age. Recent studies confirm that antiretroviral therapy should be offered to all HIV-infected patients regardless of age, symptoms, CD4+ cell count, or HIV viral load. However, when compared with HIV-uninfected populations, even with suppression of measurable HIV replication, older individuals are at greater risk for cardiovascular disease, malignancies, liver disease, and other comorbidities.

SUMMARY Human immunodeficiency virus (HIV) infection is associated with increased intestinal translocation of microbial products and enteropathy as well as alterations in gut bacterial communities. However, whether the enteric virome contributes to this infection and resulting immunodeficiency remains unknown. We characterized the enteric virome and bacterial microbiome in a cohort of Ugandan patients, including HIV-uninfected or HIV-infected subjects and those either treated with anti-retroviral therapy (ART) or untreated. Low peripheral CD4 T cell counts were associated with an expansion of enteric adenovirus sequences and this increase was independent of ART treatment. Additionally, the enteric bacterial microbiome of patients with lower CD4 T counts exhibited reduced phylogenetic diversity and richness with specific bacteria showing differential abundance, including increases in Enterobacteriaceae, which have been associated with inflammation. Thus, immunodeficiency in progressive HIV infection is associated with alterations in the enteric virome and bacterial microbiome, which may contribute to AIDS-associated enteropathy and disease progression.

This study reports the surgical outcomes of acquired immunodeficiency syndrome (AIDS) patients with Cytomegalovirus retinitis (CMVR) -related retinal detachments(RD) in an Asian population. Review of CMVR characteristics, surgical outcomes and complications in 19 eyes with CMVR-related RD that underwent surgery from January 2000 to June 2011. CMVR was inactive in 73.7% of the eyes at time of surgery. Anatomical success was achieved in 14 eyes. Seven eyes (36.8%) had improvement of two or more lines in visual acuity (VA) and 8 eyes (42.1%) maintained VA. Thirteen eyes presented with worse than 6/120 vision, with 30.8% of them achieving ambulatory vision or better. Five eyes had re-detachments. Median durations from CMVR and immune recovery uveitis (IRU) diagnoses to RD were 2.7 and 1.0 months respectively. Surgery for CMVR-related RD is associated with good anatomical outcomes with most eyes maintaining or having improved vision. CMVR lesion size of <50% retinal area is associated with better outcomes. Eyes with CMVR and IRU require close monitoring for RD.

Purpose To describe an unusual case of rapidly progressive outer retinal necrosis (PORN) with vitreous hemorrhage in a 41-year-old woman with acquired immunodeficiency syndrome (AIDS), who had retinitis developed from what was probably varicellar-zoster virus combined with cytomegalovirus (CMV) and herpes simplex type 1,2, as proven by the polymerase chain reaction restriction fragment length polymorphism method (PCR-RFLP). Methods This study is a case report detailing clinical follow-up and an aqueous humor test by PCR-RFLP. Results The deep, white retinal lesions coalesced and progressively expanded in a circumferential manner, with sparing of the perivascular retina. However, retinal and vitreous hemorrhages, unusual findings for PORN, could be noted around the optic nerve. Varicellar-zoster virus (VZV), cytomegalovirus (CMV), and herpes simplex types 1,2 (HSV-1,2) were detected in the aqueous humor by PCR. Conclusions PORN has been described as a variant of necrotizing herpetic retinopathy, occurring particularly in patients with AIDS. Although the etiologic agent has been reported to be VZV, concurrent or combined etiologic agents can include HSV-1, HSV-2, and CMV in AIDS patients. Therefore, combined antiviral therapy with acyclovir and ganciclovir could be more reasonable as an initial therapy. PMID:17460434

As the life expectancy of children with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) increases, quality-of-life outcomes are of increasing concern. The prevalence of pain in adults with AIDS ranges from 40% to 60%, depending on stage of illness. There is limited research concerning pain in HIV-infected children and youth. The General Health Assessment for Children was administered to caregivers of HIV-infected children and youth enrolled in the Pediatric Late Outcomes Study (PACTG 219), a prospective cohort study. Pain is assessed over the previous month with 7 questions. For the purpose of this analysis, we defined pain as the presence of pain of at least moderate intensity. Participants were observed from January 1, 1996, to December 31, 1999. A total of 985 HIV-positive participants had a baseline pain evaluation in 1995. The prevalence of pain remained relatively constant during each year of observation, averaging 20%. Lower CD4+ T-lymphocyte percentage, female gender, and an HIV/AIDS-related diagnosis were highly associated with an increased risk of reported pain. Pain was also independently associated with increased risk of death. After adjusting for CD4 percentage, use of combination therapy including protease inhibitors, comorbid diagnoses, and other sociodemographic characteristics, individuals reporting pain were over 5 times more likely to die than those not reporting pain (hazard ratio = 5.07; 95% confidence interval = 3.23-7.95). Pain is a frequently encountered symptom in children and youth with HIV disease and is also associated with increased mortality. These findings emphasize the importance of pain management in this population.

Although human immunodeficiency virus (HIV)-associated lipodystrophy has been reported for more than a decade, there is still considerable uncertainty regarding the mechanisms involved in its pathogenesis. A case-control study was performed that aimed to identify the risk factors for lipodystrophy in HIV/acquired immunodeficiency syndrome (AIDS) patients undergoing antiretroviral therapy in Pernambuco, Brazil. Between July and November, 2007, a total of 332 patients were enrolled in the study: 182 cases and 150 controls. The following factors were independently associated with lipodystrophy: Use of stavudine [odds ratio (OR), 4.0; 95% confidence interval (CI), 2.3-6.9], use of didanosine (OR, 1.8; 95% CI, 1.0-3.4), use of lopinavir/ritonavir for less than 3 years (OR, 0.5; 95% CI, 0.2-1.0) and use of nucleoside/nucleotide analogue reverse transcriptase inhibitors (NTRIs) for more than 3 years (OR, 2.9; 95% CI, 1.6-5.2). Other associated factors were: duration of antiretroviral therapy (OR, 4.3; 95% CI, 2.4-7.9) and duration of HIV infection (OR, 2.9; 95% CI, 1.8-4.7). There was no association with the use of protease inhibitor when it was adjusted for the use of NRTIs. In this study, factors related to antiretroviral therapy were the main risk factors for lipodystrophy, corroborating the literature, but the findings also point to the need for further exploration into some of these associations, especially with the use of didanosine and lopinavir/ritonavir, which are less frequently reported. Future studies with a larger number of patients and a prospective design could provide valuable information for understanding this disorder.

A 49-year-old man presented with gradually progressive aphasia one month after being diagnosed with acquired immunodeficiency syndrome (AIDS). Brain magnetic resonance imaging showed multiple brain lesions with punctate and linear enhancement. A polymerase chain reaction detected Epstein-Barr virus (EBV) in the patient's cerebrospinal fluid. A diagnosis of isolated central nervous system lymphomatoid granulomatosis (CNS-LYG) was made based on the brain biopsy findings. The complete remission of CNS-LYG was achieved by anti-retroviral therapy (ART) alone. In the present case, the development of AIDS-associated CNS-LYG was considered to have been initiated by the reactivation of EBV in the CNS under immunosuppressive conditions. The patient's condition improved with the reconstitution of the patient's immune system.

To assess serum retinol and levels of carotenoids in children and adolescents with acquired immunodeficiency syndrome (AIDS) and to correlate low serum retinol and carotenoid levels with the presence of lipodystrophy, lipid profile changes, lipid peroxidation, and insulin resistance. A cross-sectional, controlled observational study was carried out with 30 children and adolescents with AIDS (mean age 9.1 y) receiving antiretroviral therapy (median length of treatment 28.4 mo), including 30 uninfected healthy controls matched for age and gender. Clinical and laboratory assessments were performed to determine nutritional status, presence of lipodystrophy, serum concentrations of retinol, beta-carotene, lycopene, lipid profile (high-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triacylglycerols), lipid peroxidation (thiobarbituric acid-reactive substances), glycemia, and serum insulin (homeostasis model assessment for insulin resistance, cutoff point >3). Statistical analysis was done with chi-square test and Student's t test. Lipodystrophy was observed in 53.3% of patients with AIDS, and dyslipidemia was detected in 60% and 23% of subjects with human immunodeficiency virus and control subjects, respectively (P = 0.004). A higher prevalence of retinol deficiency (60% versus 26.7%, P = 0.009) and beta-carotene deficiency (23.3% versus 3.3%, P = 0.026) was found in the group with human immunodeficiency virus than in the control group. No correlation was found for low retinol and beta-carotene levels, changes in lipid and glucose metabolism, or lipodystrophy in children and adolescents with AIDS. Despite the high frequency of dyslipidemia, lipodystrophy, and retinol and beta-carotene deficiencies, it was not possible to demonstrate a correlation of these findings with lipid peroxidation and insulin resistance. More studies are needed to investigate the causes of retinol and beta-carotene deficiencies in this population and the clinical

Kaposi's sarcoma (KS) is an angioproliferative lesion that may regress or progress. Progression is related to spindle cell proliferation and the expression of human herpes virus-8 latency genes, including latent nuclear antigen-1 (LNA-1), cyclin-D1, and bcl-2. KS regression has not been well characterized histologically. Therefore, this study was undertaken to characterize the histopathology of pharmacologically induced regressed cutaneous KS. Skin punch biopsies from eight patients with acquired immunodeficiency syndrome (AIDS)-related KS, that regressed following chemotherapy with paclitaxel or the angiogenesis inhibitor Col-3, were investigated by light microscopy. Comparative immunophenotyping on pre- and post-treatment specimens for CD31, LNA-1, cyclin-D1, bcl-2, and CD117 (c-kit) was performed. Clinical and histologic features of regression were similar for paclitaxel and Col-3 treatment. On clinical examination, lesions flattened, became smaller, and lost their purple-red appearance, resulting in an orange-brown macule. Histological regression was divided into partial (n = 3) and complete (n = 5) regression. Partially regressed lesions had a significant reduction of spindle cells in the dermal interstitium, with residual spindle cells arranged around superficial and mid-dermal capillaries. Complete regression was characterized by an absence of detectable spindle cells, with a slight increase in capillaries of the superficial plexus. All regressed samples exhibited a prominent, superficial, perivascular, lymphocytic infiltrate and abundant dermal hemosiderin-laden macrophages. This clinicopathologic picture resembled the findings of pigmented purpura. CD31 staining correlated with the reduction of spindle cells. Regression was accompanied by a quantitative and qualitative decrease in LNA-1 and cyclin-D1 immunoreactivity, but no change in bcl-2 or c-kit expression. Pharmacologically induced regression of AIDS-related cutaneous KS is characterized by a complete

Human immunodeficiency virus (HIV) infection in India has now been prevalent over three decades, and an increasing number of children are being affected with HIV. The spectrum of pathologic lesions in children with acquired immunodeficiency syndrome (AIDS) in India has not been well described. A review of systematically conducted autopsies of 11 (10 boys and 1 girl) children with AIDS is presented. The mode of HIV transmission in 6 children was vertical; in one it was blood transfusion and in 4 children route was presumably vertical as these were children of orphanage. The clinical manifestations were failure to thrive; 9 children, persistent gastroenteritis; 8, recurrent fever; 5, bacterial infections; 5, hepatosplenomegaly; 5, candidiasis; 1, scabies; 1, skin rash; 2, tuberculous (TB) meningitis; 1 and paraplegia; in 1 child. The spectrum of pathologic lesions observed were precocious involution in thymus in 3 and dysinvolution in 2 cases. Infectious diseases comprised of TB; 4 cases, cytomegalovirus infection (CMV) 4; bacterial pneumonia and meningitis; 7, and esophageal candidiasis in 2 cases. Dual or multiple infections were observed in 9 (82%) cases; these comprised of two lesions in 2, three lesions in 2, four lesions in 4, and five lesions in 1 case. TB, bacterial pneumonia, meningitis, and CMV infection are the most frequent causes of death in children with AIDS. Vascular lesions showing features of arteriopathy were observed in 5 cases and brain in one case showed non-Hodgkin's lymphoma. This study provides a better insight into the spectrum of pathologic lesions in children with AIDS in India. TB and CMV infection has been found to be the most prevalent infection in our children.

To assess the histopathological, immunohistochemical (IHC), and in situ hybridization (ISH) features found in the submandibular (SM) and sublingual (SL) glands of 105 acquired immunodeficiency syndrome (AIDS) patients at autopsy. Gender, age, CD4 cell level, and clinical histories were obtained from clinical charts (SM: n = 103; SL: n = 92). Histologic analysis of hematoxylin and eosin, Gomori-Grocott, and Ziehl-Neelsen stained tissues, IHC to detect infectious agents and characterize inflammatory cells in sialadenitis, and ISH for EBER-1/2 were performed. The mean age of the patients and CD4 cell count were 36 years and 76 cells/microL, respectively. Fifty-eight cases (SM: n = 51 [49%]; SL: n = 54 [59%]) were considered to be microscopically normal. The most common infectious conditions were mycobacteriosis (SM: n = 11 [10%]; SL: n = 7 [7%]), followed by cytomegalovirus (CMV) (SM: n = 14 [13%]; SL: n = 2 [2%]), and cryptococcosis (SM: n = 3 [3%]; SL: n = 4 [4%]). Human immunodeficiency virus (HIV) p24 (SM: n = 2 [2%]; SL: n = 1 [1%]) and EBER-1/2 (SM: n = 9 [39%]; SL: n = 4 [20%]) were seen only in macrophages and lymphocytes, respectively. The most prevalent cells seen in chronic nonspecific sialadenitis (SM: n = 25; SL: n = 25) were CD8+ T lymphocytes, whereas CD68+ macrophages were predominant in the mycobacteriosis-associated granulomatous and nonspecific diffuse macrophagic sialadenitis. Concomitant infections occurred in 5 cases (SM: n = 4; SL: n = 1) and non-Hodgkin lymphoma in 1 case. Infectious diseases and chronic nonspecific sialadenitis were the main alterations found in the SM and SL glands. These alterations were greater in the SM than in the SL glands. CD8+ T lymphocytes and CD68+ macrophages might be relevant to the pathogenesis of the sialadenitis. Clinicians should consider these diseases when assessing the major salivary glands in advanced AIDS patients and follow biosafety procedures to avoid contamination by HIV, CMV, mycobacteriosis, and

Low incidence of human immunodeficiency virus (HIV) infections and acquired immunodeficiency syndrome (AIDS) has been detected in Croatia so far. Toxoplasmic encephalitis (TE) is the most common opportunistic cerebral infection in AIDS patients and is highly responsive to antiparasitic chemotherapy, if treated at an early stage. We present the case of the brain biopsy confirmed as TE on a 36-year-old female patient who at admission presented with unconsciousness and a right hemiplegia. A MSCT was performed and two hypodense lesions were diagnosed. The patient’s family initially denied the presence or history of any medical problem or infection. An MRI showed multiple ring-enhanced mass lesions. An infectologist required a brain biopsy to exclude cerebral lymphoma and multiple metastases. Pathohistological analysis suggested TE. Meanwhile, patient’s blood samples were found to be HIV positive. The patient was transferred to University Hospital for Infectious Diseases in Zagreb, where she died 2 days following admission. The patient’s family terminally confessed that the patient had been HIV positive for 10 years and had refused any treatment. Family’s denial of infection as well as ‘hiding information’ concerning patient’s health from physicians involved in her treatment caused a delay in proper on-time patient treatment. We would like to emphasize that TE must be considered as a differential diagnosis in patients presenting with multiple cerebral lesions, including patients without acknowledged past history of HIV infection. A stigma towards HIV infection and ignorance of the disease still exist and therefore hinders proper treatment. PMID:24091082

The aims of this study were to compare outcomes of appendectomy between acquired immunodeficiency syndrome (AIDS) and nonAIDS patients and laparoscopic appendectomy (LA) versus open appendectomy (OA) in AIDS patients. Using the Nationwide Inpatient Sample database, from 2006 to 2008, clinical data of patients with AIDS who underwent LA and OA were evaluated. A total of 800 patients with AIDS underwent appendectomy during these years. Patients with AIDS had a significantly higher postoperative complication rate (22.56% vs 10.36%), longer length of stay [(LOS) 4.9 vs 2.9 days], and higher mortality (0.61% vs 0.16%) compared with non-AIDS patients. In nonperforated cases in patients with AIDS, LA was associated with a significantly lower complication rate (11.25% vs 21.61%), lower mortality (0.0% vs 2.78%), and shorter mean LOS (3.22 days vs 4.82 days) compared with OA. In perforated cases in patients with AIDS, LA had a significantly lower complication rate (27.52% vs 57.50%), and shorter mean LOS (5.92 days vs 9.67 days) compared with OA. No mortality was reported in either group. In patients with AIDS, LA has a lower morbidity, lower mortality, and shorter LOS compared with OA. Laparoscopic appendectomy should be considered as a preferred operative option for acute appendicitis in patients with AIDS.

PURPOSE To investigate the relationship between contrast sensitivity (CS) and mortality among people with acquired immunodeficiency syndrome (AIDS); and to explore the hypothesis that abnormal CS is a marker of systemic, life-threatening microvascular disease. DESIGN Longitudinal, observational cohort study. METHODS We evaluated 3395 eyes of 1706 individuals enrolled in the Longitudinal Study of the Complications of AIDS (1998–2008). CS was evaluated as a risk factor for death, and was compared to the presence of systemic diseases characterized by microvasculopathy (diabetes, cardiovascular disease, stroke, renal disease) and to laboratory markers of those diseases. Abnormal CS was defined as logCS <1.5 (lower 2.5th percentile for a normal control population). RESULTS CS was abnormal in 284 of 1691 (16.8%) study participants at enrollment. There was a positive relationship between the presence of abnormal CS at study entry and mortality (relative risk 2.0, 95% confidence interval 1.7-2.3, P < .0001). Abnormal CS was related to the presence of cardiovascular disease, stroke, and renal disease (all P values < .01), but abnormal CS remained associated with death even after adjustment for these diseases and for other known predictors of death among people with AIDS. Diseases characterized by microvasculopathy were more often identified as causes of death among individuals with abnormal CS than among those with normal CS, although the strength of the association was moderate (P = .06). CONCLUSIONS Abnormal CS among people with AIDS is associated with increased mortality, and is independent of other risk factors for death that are monitored routinely. The relationship may indicate life-threatening microvascular disease in other organs. PMID:20399927

Human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) adversely impacts food security in households of people living with HIV/AIDS (PLWHA). Little research has focused on food insecurity among PLWHA in India. The purpose of this study was to identify the prevalence of and factors relating to food security in households of PLWHA in the Siliguri subdivision of Darjeeling, West Bengal, India. A cross-sectional community-based study was carried out among 173 PLWHA residing in Siliguri and registered at the Anti-retroviral Therapy Centre of North Bengal Medical College & Hospital. Data was collected at the household level with interviews of PLWHA using a food security survey instrument. We analyzed the associations using logistic regression. The prevalence of household food security among the participants was 50.9% (88/173). Five years or more of schooling, higher socioeconomic class and males were found to be significantly associated with a higher likelihood of food security. A later stage of the disease and the presence of other family members with HIV/AIDS were significantly associated with a lower likelihood of food security. The major coping strategies to deal with food insecurity in the acute phase HIV infection included borrowing money (56.1%), followed by spousal support, loans from microfinance institutions, banks, or money lenders, borrowing food, or selling agricultural products. The present study revealed that only about half of households with PLWHA were food secure. Prior interventions relating to periods of food and economic crisis as well as strategies for sustaining food security and economic status are needed in this area.

AIM To compare the clinical manifestation of cytomegalovirus (CMV) retinitis and microvascular retinopathy (MVR) in patients with acquired immunodeficiency syndrome (AIDS) in China. METHODS A total of 93 consecutive patients with AIDS, including 41 cases of CMV retinitis and 52 cases of MVR were retrospectively reviewed. Highly active antiretroviral therapy (HAART) status was recorded. HIV and CMV immunoassay were also tested. CD4+ T-lymphocyte count and blood CMV-DNA test were performed in all patients. Aqueous humor CMV-DNA test was completed in 39 patients. Ophthalmological examinations including best corrected visual acuity (BCVA, by International Standard Vision Chart), intraocular pressure (IOP), slit-lamp biomicroscopy, indirect ophthalmoscopy were performed. RESULTS In MVR group, the anterior segment examination was normal in all patients with a mean BCVA of 0.93±0.13. Blood CMV-DNA was 0 (0, 269 000) and 42 patients (80.77%) did not receive HAART. In CMV retinitis group, 13 patients (31.71%) had anterior segment abnormality. The mean BCVA was 0.64±0.35 and blood CMV-DNA was 3470 (0, 1 450 000). Nineteen patients (46.34%) had not received HAART. MVR group and CMV retinitis group the positive rates of aqueous CMV-DNA were 0 and 50%, respectively. Two patients with MVR progressed to CMV retinitis during the follow-up period. CONCLUSION In comparison of CMV, patients with MVR have relatively mild visual function impairment. Careful ophthalmological examination and close follow-up are mandatory, especially for patients who have systemic complications, positive CMV-DNA test and without received HAART. PMID:28944199

Two women with advanced human immunodeficiency virus infection are described who were seen with painful aphthous vaginal ulceration and CD4+ lymphocyte counts < 50 cells/mm3. A chronic rectovaginal fistula developed in one patient. In spite of extensive investigation no underlying cause of the ulceration was discovered. Clinical therapeutic response suggests that corticosteroid therapy may be of value in healing or stabilizing the destructive process. Clinicians should be aware of this complication in human immunodeficiency virus-infected women with severe vaginal pain and unexplained discharge.

Cryptococcosis occurs in acquired immunodeficiency syndrome (AIDS) patients with poor compliance to antiretroviral therapy or unaware of their human immunodeficiency virus status who present severe immunosuppression at admission. Consequently, high mortality rates are observed due to disseminated fungal infection. This report presents clinical and postmortem data of AIDS patients with cryptococcosis in a teaching hospital in Brazil. Retrospectively, medical and necropsy records of AIDS patients with cryptococcosis clinically confirmed and/or postmortem verified were reviewed. Clinical data were compared with those of patients presenting a good outcome to evaluate disseminated fungal infection and the agreement between clinical and postmortem diagnosis. At admission, most of the 45 patients with cryptococcal meningitis who died, presented more altered consciousness (P = 0.0047), intracranial increased pressure (P = 0.047), and severe malnutrition (P = 0.0006) than the survivors. Of 29 (64.4%) patients with cryptococcal meningitis, 23 died before week 2 on antifungal therapy, and the other six during the next 3 months. The remaining 16 (35.6%) cases had other diagnoses and died soon after. At necropsy, 31 (68.9%) presented disseminated infection involving two or more organs, whereas 14 (31.1%) cases had meningeal or pulmonary localized infection. The agreement of 64.4% between clinical and postmortem diagnosis was similar to some studies. However, other reports have shown figures ranging from 34% to 95%. Currently, a progressive worldwide decrease of autopsies is worrying because the role of postmortem examination is pivotal to verify or identify the death causes, which contributes to improve the quality of clinical diagnosis and medical training.

Castleman's Disease is a rare B-cell lymphoproliferative disease. It is mostly benign and is characterized by non-neoplastic lymph node hypertrophy, associated with infection by human herpesvirus-8 in people with the human immunodeficiency virus/acquired immunodeficiency syndrome. Although the unicentric or localized form presents as benign, the multifocal form can manifest severe systemic symptoms. We report two unusual cases of men presenting cervical enlarged lymph nodes that were believed to be infectious. The first case is a 41-year-old feoderm man who presented to the Department of Infectious Diseases of the Hospital das Clínicas in May 2015, with irregular fever history (38-39 °C), dyspnea, weight loss (8 kg/1 year), and asthenia with increased cervical lymph nodes of 1-year duration. His immunohistochemical diagnosis presented Castleman's disease in plasmacytic/diffuse form. In the second case, a 35-year-old feoderm man presented at the same hospital with multiple cervical enlarged lymph nodes and histopathological evidence of Castleman's disease associated with human herpesvirus-8. Considering the importance of differential diagnosis of lymphoid disorders, Castleman's disease is a challenging diagnosis in people living with human immunodeficiency virus/acquired immunodeficiency syndrome and can be easily misdiagnosed when lymphoid disorders are present in the human immunodeficiency virus/acquired immunodeficiency syndrome population due to nonspecific symptoms and signs.

Despite increased funding for research on the human immunodeficiency virus (HIV) and the acquired immunodeficiency syndrome (AIDS), neither vaccine nor cure is yet in sight. Surveillance and prevention are essential for disease intervention, and it is recognised that spatio-temporal analysis of AIDS cases can assist the decision-making process for control of the disease. This study investigated the dynamic, spatial distribution of notified AIDS cases in the State of Rio de Janeiro, Brazil, between 2001 and 2010, based on the annual incidence in each municipality. Sequential choropleth maps were developed and used to analyse the incidence distribution and Moran's I spatial autocorrelation statistics was applied for characterisation of the spatio-temporal distribution pattern. A significant, positive spatial autocorrelation of AIDS incidence was observed indicating that municipalities with high incidence are likely to be close to other municipalities with similarly high incidence and, conversely, municipalities with low incidence are likely to be surrounded by municipalities with low incidence. Two clusters were identified; one hotspot related to the State Capital and the other with low to intermediate AIDS incidence comprising municipalities in the north-eastern region of the State of Rio de Janeiro.

Background: Scientific publication is commonly used to communicate research findings and in most academic/research settings, to evaluate the potential of a researcher and for recruitment and promotion. It has also been said that researchers have the duty to make public, the findings of their research. As a result, researchers are encouraged to share their research findings with the scientific world through peer review publications. In this study, we looked at the characteristics and publication rate of theses that documented studies on human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome in Cameroon. Materials and Methods: To check if a thesis resulted in a publication, we searched: A database of publications on HIV in Cameroon, African Journals Online, PubMed and Google scholar. For each publication we recorded if the student was an author, the position of the student in the author listing, the journal and where the journal was indexed. We also looked at the impact factor of the journals. Results: One hundred and thirty theses/dissertations were included in the study, 74.6% (97/130) were written as part of a medical degree (MD), 23.8% (31/130) a postgraduate (PG) degree and 1.5% (2/130) for a Doctorate/PhD. On a whole, 13.9% (18/130) of the theses resulted in at least one publication in a scientific journal with a total of 22 journal articles, giving a mean publication rate of 0.17 article/thesis, 86.4% (11/22) were indexed on PubMed, 9.1% (2/22) on African Journals Online and 4.6% (1/22) on Google scholar. One PG thesis led to two book chapters. The student was the first author in 22.7% (5/22) of the articles and not an author in 9.1% (2/22) of the articles. Student supervisor was an author in all the articles. Conclusion: This study reveals that most students in Cameroon failed to transform their theses/dissertations to scientific publications. This indicates an urgent need to sensitize students on the importance of presenting their research

2011-07-01

We report a rare case of human Taenia crassiceps infection in a 47-year-old female patient with untreated acquired immunodeficiency syndrome and chronic hepatitis C infection. Little experience exists regarding the appropriate treatment of this infection. Usually, a combination of anthelmintic drugs is applied. Whether surgical measures are indicated have not been clarified. In our patient, initial surgery showed an abscess and fluid collection with numerous transparent cysts localised in the subcutaneous tissue of the cubital fossa. Parasitological and pathological examinations identified these structures as larvae of the cestode T. crassiceps. After treatment with anthelmintic medications, the patient was discharged in good condition. However, the patient presented with the clinical symptoms of an acute fasciitis of the right upper extremity 7 days later. The deteriorating general condition entailing a pre-septical state demanded emergency debridement and fasciectomy of the right arm. After the surgery, the patient recovered fully. Surgical treatment appears to be an important measure to reduce the tissue parasite load in patients with severe immunodeficiency. It also has to be questioned whether the bioavailability and the penetration of the drugs commonly administered is sufficiently high to treat such a fulminant infection alone.

predominantly at 1 × 106 copies/ml or greater developed encephalitis. To further investigate the relationship between CD163+/CD16+ MΦs/microglia in the CNS and altered homeostasis in the periphery, the authors performed flow-cytometric analyses of peripheral blood mononuclear cells (PBMCs) from SIV-infected rhesus macaques. The results demonstrate an increase in the percent frequency of CD163+/CD16+ monocytes in animals with detectable virus that correlated significantly with increased viral burden and CD4+ T-cell decline.

whose viral burden was predominantly at 1 x 10(6) copies/ml or greater developed encephalitis. To further investigate the relationship between CD163(+)/CD16(+) MPhis/microglia in the CNS and altered homeostasis in the periphery, the authors performed flow-cytometric analyses of peripheral blood mononuclear cells (PBMCs) from SIV-infected rhesus macaques. The results demonstrate an increase in the percent frequency of CD163(+)/CD16(+) monocytes in animals with detectable virus that correlated significantly with increased viral burden and CD4(+) T-cell decline. These results suggest the importance of this monocyte subset in HIV/SIV CNS disease, and also in the immune pathogenesis of lentiviral infection. The authors further discuss the potential role of CD163(+)/CD16(+) monocyte/MPhi subset expansion, altered myeloid homeostasis, and potential consequences for immune polarization and suppression.

Invasive fungal infections (IFIs) represent one of the main causes of morbimortality in immunocompromised patients. Pneumocystosis, cryptococcosis and histoplasmosis are the most frequently occurring IFIs in patients with acquired immunodeficiency syndrome (AIDS). Fungi, such as Candida spp. and Aspergillus spp., may cause severe diseases during the course of an HIV infection. Following the introduction of highly active anti-retroviral therapy, there has been a marked reduction of opportunistic fungal infections, which today is 20-25 % of the number of infections observed in the mid-1990s. This study is an observational and retrospective study aimed at the characterising IFI incidence and describing the epidemiology, clinical diagnostic and therapeutic features and denouement in HIV/AIDS patients. In HIV/AIDS patients, the IFI incidence is 54.3/1,000 hospitalisation/year, with a lethality of 37.7 %. Cryptococcosis represents the main opportunistic IFI in the population, followed by histoplasmosis. Nosocomial pathogenic yeast infections are caused principally by Candida spp., with a higher candidemia incidence at our institution compared to other Brazilian centres.

Human immunodeficiency virus vaccination and pre-exposure prophylaxis represent two different emerging preventive tools. Google Trends was used to assess the public interest toward these tools in terms of digital activities. Worldwide web searches concerning the human immunodeficiency virus vaccine represented 0.34 percent, 0.03 percent, and 46.97 percent of human immunodeficiency virus, acquired immune deficiency syndrome, and human immunodeficiency virus/acquired immune deficiency syndrome treatment-related Google Trends queries, respectively. Concerning temporal trends, digital activities were shown to increase from 0 percent as of 1 January 2004 percent to 46 percent as of 8 October 2017 with two spikes observed in May and July 2012, coinciding with the US Food and Drug Administration approval. Bursts in search number and volume were recorded as human immunodeficiency virus vaccine trials emerged. This search topic has decreased in the past decade in parallel to the increase in Truvada-related topics. Concentrated searches were noticed among African countries with high human immunodeficiency virus/acquired immune deficiency syndrome prevalence. Stakeholders should take advantage of public interest especially in preventive medicine in high disease burden countries.

Cryptococcosis occurs in acquired immunodeficiency syndrome (AIDS) patients with poor compliance to antiretroviral therapy or unaware of their human immunodeficiency virus status who present severe immunosuppression at admission. Consequently, high mortality rates are observed due to disseminated fungal infection. This report presents clinical and postmortem data of AIDS patients with cryptococcosis in a teaching hospital in Brazil. Retrospectively, medical and necropsy records of AIDS patients with cryptococcosis clinically confirmed and/or postmortem verified were reviewed. Clinical data were compared with those of patients presenting a good outcome to evaluate disseminated fungal infection and the agreement between clinical and postmortem diagnosis. At admission, most of the 45 patients with cryptococcal meningitis who died, presented more altered consciousness (P = 0.0047), intracranial increased pressure (P = 0.047), and severe malnutrition (P = 0.0006) than the survivors. Of 29 (64.4%) patients with cryptococcal meningitis, 23 died before week 2 on antifungal therapy, and the other six during the next 3 months. The remaining 16 (35.6%) cases had other diagnoses and died soon after. At necropsy, 31 (68.9%) presented disseminated infection involving two or more organs, whereas 14 (31.1%) cases had meningeal or pulmonary localized infection. The agreement of 64.4% between clinical and postmortem diagnosis was similar to some studies. However, other reports have shown figures ranging from 34% to 95%. Currently, a progressive worldwide decrease of autopsies is worrying because the role of postmortem examination is pivotal to verify or identify the death causes, which contributes to improve the quality of clinical diagnosis and medical training. © The American Society of Tropical Medicine and Hygiene.

The human immunodeficiency virus (HIV) infection which manifests as acquired immunodeficiency syndrome (AIDS) is a disease involving the defects of the T-lymphocyte arm of the immune system. Certain laboratory parameters such as the cluster of differentiation (CD4) count and clinical parameters have long been used as markers of disease progression. In industrialized countries, many studies show a highly correlation between the incidence of oral lesions and immunosuppression and hence, can be used as a marker of immunosuppression. This might not be applicable to a developing country like India. In this study, efforts have been made to supplement the present knowledge on various aspects of oral manifestations in HIV patients in the Indian subcontinent. To correlate the oral manifestations in HIV/AIDS patients to the level of circulating CD4+ T-lymphocyte count and their effect in anti-retroviral therapy (ART). A total of 104 HIV positive patients were examined for oral lesions. The CD4 count estimated on the same day by fluorescent activated cell sort count machine was then correlated with various oral lesions. Oral manifestations appeared when CD4 count decreased below 500 cells/mm 3 . Moreover, oral lesions found at different stages showed very strong correlation to their respective CD4 count. Furthermore, there was considerable decline in the incidence of oral manifestations in patients undergoing highly active ART. Oral manifestations are highly predictive markers of severe immune deterioration and disease progression in HIV patients.

To analyze the effect of Chinese medicine (CM) on mortality and quality of life (QOL) of acquired immunodeficiency syndrome (AIDS) patients treated with combined antiretroviral therapy (cART). A random sample of AIDS patients enrolled in the National Chinese Medicine Treatment Trial Program (NCMTP) that met the inclusion criteria was included in this study. NCMTP patients were included as the CM+cART group, and those not in the NCMTP were included as the cART group. Survival from September 2004 to September 2012 was analyzed by retrospective cohort study. QOL was analyzed by cross-sectional study. The retrospective cohort study included 528 AIDS patients, 322 in the CM+cART group and 206 in the cART group. After 8 years, the mortality in the CM+cART group was 3.3/100 person-years, which was lower than the cART group of 5.3/100 person-years (P <0.05). The hazard ratio (HR) for mortality in the cART group was 1.6 times that of the CM+cART group by Cox proportional hazard model analysis. After controlling for gender, age, marital status, education, and CD4 T-cell count, the HR was 1.9 times higher in the cART group compared with the CM+cART group (P <0.05). The cross-sectional study investigated 275 AIDS patients. The mean scores of all QOL domains except spirituality/personal beliefs were higher in the CM+cART group than in the cART group (P <0.05). For AIDS patients, CM could help to prolong life, decrease mortality, and improve QOL. However, there were limitations in the study, so prospective studies should be carried out to confirm our primary results.

Summary Tuberculosis (TB), caused by Mycobacterium tuberculosis (M.tb) and a few related mycobacteria, is a devastating disease, killing more than a million individuals per year worldwide. However, its pathogenesis remains largely elusive, as only a small proportion of infected individuals develop clinical disease either during primary infection or during reactivation from latency or secondary infection. Subacute, hematogenous, and extrapulmonary disease tends to be more frequent in infants, children, and teenagers than in adults. Life-threatening primary TB of childhood can result from known acquired or inherited immunodeficiencies, although the vast majority of cases remain unexplained. We review here the conditions conferring a predisposition to childhood clinical diseases caused by mycobacteria, including not only M.tb but also weakly virulent mycobacteria, such as BCG vaccines and environmental mycobacteria. Infections with weakly virulent mycobacteria are much rarer than TB, but the inherited and acquired immunodeficiencies underlying these infections are much better known. Their study has also provided genetic and immunological insights into childhood TB, as illustrated by the discovery of single-gene inborn errors of IFN-γ immunity underlying severe cases of TB. Novel findings are expected from ongoing and future human genetic studies of childhood TB in countries that combine a high proportion of consanguineous marriages, a high incidence of TB, and an excellent clinical care, such as Iran, Morocco, and Turkey.

Even in cases where viral replication has been controlled by antiretroviral therapy for long periods of time, human immunodeficiency virus (HIV)-infected patients have several non-acquired immunodeficiency syndrome (AIDS) related co-morbidities, including liver disease, cardiovascular disease and neurocognitive decline, which have a clear impact on survival. It has been considered that persistent innate and acquired immune activation contributes to the pathogenesis of these non-AIDS related diseases. Immune activation has been related with several conditions, remarkably with the bacterial translocation related with the intestinal barrier damage by the HIV or by hepatitis C virus (HCV)-related liver cirrhosis. Consequently, increased morbidity and mortality must be expected in HIV-HCV coinfected patients. Disrupted gut barrier lead to an increased passage of microbial products and to an activation of the mucosal immune system and secretion of inflammatory mediators, which in turn might increase barrier dysfunction. In the present review, the intestinal barrier structure, measures of intestinal barrier dysfunction and the modifications of them in HIV monoinfection and in HIV-HCV coinfection will be considered. Both pathogenesis and the consequences for the progression of liver disease secondary to gut microbial fragment leakage and immune activation will be assessed.

Influence of the greenhouse effect on human health through stratospheric cooling: Possible increase in acquired immunodeficient syndrome

The greenhouse effect cools the stratosphere and increases formation of PSC (polar stratospheric cloud) in polar regions and enhances ozone depletion. If the enhanced ozone depletion diffused to lower latitudes, it could increase ultraviolet radiation (UV), which might increase acquired immunodeficiency syndrome (AIDS). Epidemiological studies are made to test this hypothesis. The relation between AIDS prevalence R and latitude {theta}. Comparison of analyses shows that R of Caucasians would be higher than Non-Caucasians at the same {theta}. These trends are similar to those of skin cancers known to be caused by UV. In developing countries poverty, malnutrition, etc., could causemore » high R, and since most developing countries are located at low {theta}, the low {theta} increase may be due to these factors. However if so in Africa they are about the same and the low {theta} increase would disappear, but data on African countries also show the low {theta} increase and the significant correlation. Some countries at low {theta} have low R, probably because HIV is not prevalent for them. Then the upper envelope of the distribution of R would be cases when HIV is prevalent and UV is most effective. Therefore analyses are repeated using maxima of R within intervals of {theta} of 1, 3 and 5{degree}. In all cases the low {theta} increase and the correlation becomes more significant. These results support the hypothesis that AIDS is promoted by UV.« less

Although prior studies suggest reduced androgen levels in women with acquired immune deficiency syndrome wasting, little is known regarding the regulation of adrenal and ovarian androgen secretion in such patients. We investigated ovarian and adrenal function in 13 human immunodeficiency virus-infected women with acquired immune deficiency syndrome wasting and 21 age- and body mass index-matched healthy control subjects studied in the early follicular phase. Subjects received hCG (5000 U, im) on d 1 and Cosyntropin (0.25 mg, i.v.) on d 3 after dexamethasone (1 mg, orally, at 2400 h) pretreatment on d 2. At baseline, human immunodeficiency virus-infected subjects demonstrated significantly reduced T [18 +/- 2 vs. 25 +/- 2 ng/dl (0.6 +/- 0.1 vs. 0.9 +/- 0.1 nmol/liter); P = 0.02], free T [1.5 +/- 0.1 vs. 2.4 +/- 0.2 pg/ml (5.3 +/- 0.5 vs. 8.3 +/- 0.6 pmol/liter); P = 0.001], androstenedione [119 +/- 6 vs. 162 +/- 14 ng/dl (4.16 +/- 0.20 vs. 5.66 +/- 0.48 nmol/liter); P = 0.02], and dehydroepiandrosterone sulfate [0.96 +/- 0.17 vs. 1.55 +/- 0.19 microg/ml (2.6 +/- 0.5 vs. 4.2 +/- 0.5 micromol/liter); P = 0.047] levels compared with the control subjects. T [8 +/- 2 vs. 6 +/- 2 ng/dl (0.3 +/- 0.1 vs. 0.2 +/- 0.1 nmol/liter); P = 0.48], free T [0.5 +/- 0.2 vs. 0.4 +/- 0.1 pg/ml (1.7 +/- 0.7 vs. 1.5 +/- 0.5 pmol/liter); P = 0.85], 17 hydroxyprogesterone [0.5 +/- 0.2 vs. 0.7 +/- 0.2 microg/liter (1.6 +/- 0.6 vs. 2.0 +/- 0.6 nmol/liter); P = 0.63], and androstenedione [-1 +/- 12 vs. 8 +/- 11 ng/dl (-0.03 +/- 0.42 vs. 0.28 +/- 0.39 nmol/liter), P = 0.61] responses to hCG were not different between the groups. Cortisol responses were increased and dehydroepiandrosterone sulfate responses were decreased in the human immunodeficiency virus-infected vs. control subjects after ACTH stimulation. The ratio of DHEA to cortisol was significantly decreased at 60 (71 +/- 11 vs. 107 +/- 10; P = 0.02) and 90 (63 +/- 8 vs. 102 +/- 9; P = 0.004) min post-ACTH in the human immunodeficiency

The overall burden of cancer may increase as individuals with acquired immunodeficiency syndrome (AIDS) live longer because of highly active antiretroviral therapy (HAART), which has been widely available since 1996. A population-based, record-linkage study identified cancers in 472,378 individuals with AIDS from 1980 to 2006. By using nonparametric competing-risk methods, the cumulative incidence of cancer was estimated across 3 calendar periods (AIDS onset in 1980-1989, 1990-1995, and 1996-2006). Measured at 5 years after AIDS onset, the cumulative incidence of AIDS-defining cancer (ADC) declined sharply across the 3 AIDS calendar periods (from 18% in 1980-1989, to 11% in 1990-1995, to 4.2% in 1996-2006 [ie, the HAART era]). The cumulative incidence of Kaposi sarcoma declined from 14.3% during 1980 to 1989, to 6.7% during 1990 to 1995, and to 1.8% during 1996 to 2006. The cumulative incidence of non-Hodgkin lymphoma (NHL) declined from 3.8% during 1990 through 1995 to 2.2% during 1996 through 2006; during the HAART era, NHL was the most common ADC (53%). The cumulative incidence of non-AIDS-defining cancer (NADC) increased from 1.1% to 1.5% with no change thereafter (1%; 1996-2006), in part because of declines in competing mortality. However, cumulative incidence increased steadily over time for specific NADCs (anal cancer, Hodgkin lymphoma, and liver cancer). The cumulative incidence of lung cancer increased from 0.14% during 1980 to 1989 to 0.32% during 1990 to 1995, and no change was observed thereafter. Dramatically declining cumulative incidence was noted in 2 major ADCs (Kaposi sarcoma and NHL), and increases were observed in some NADCs (specifically, cancers of the anus, liver, and lung and Hodgkin lymphoma). As HIV/AIDS is increasingly managed as a chronic disease, greater attention should be focused on cancer screening and prevention. Published 2010 American Cancer Society.

Background and Objectives: Human immunodeficiency virus (HIV) is a major public health challenge. Unjustified calls for the isolation of patients with HIV infection might further constrain the potential for expansion of clinical services to deal with a greater number of such patients. This infectious illness can evoke irrational emotions and fears in health care providers. Keeping this in view, a study was conducted to assess the knowledge and attitudes related to HIV/acquired immune deficiency syndrome (AIDS) among dental and medical students. Methodology: Descriptive cross-sectional survey of the entire dental and medical undergraduate students from two colleges was carried out using a pretested, self-administered questionnaire. Descriptive statistics such as percentage was used to present the data. Results: Ninety-eight percentage medical and dental undergraduate graduate students knew about HIV transmission in the hospital. Journals and internet were the leading source of information among both medical and dental undergraduates. The majority of respondents discussed HIV-related issues with their classmates. Surprisingly, 38% medical and 52% dental undergraduates think that HIV patient should be quarantined (isolation) to prevent the spread of infection. 68% medical and 60% dental undergraduates are willing to rendering dental/medical care to HIV-infected patients. Relatively large proportion (98%) of participants was willing to participate for HIV prevention program. Conclusion: The knowledge of medical and dental students is adequate, but the attitude needs improvement. Dental and medical students constitute a useful public health education resource. Comprehensive training, continuing education, and motivation will improve their knowledge and attitude, which enable them to provide better care to HIV patients. PMID:26538940

Risky sexual behaviour and human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) among healthcare workers.

South Africa is known to have one of the highest prevalence rates of human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) globally, with one in seven healthcare workers being HIV-positive. An HIV-positive healthcare workforce is less equipped to respond to the increasing spread of the epidemic. Assessment of the factors contributing to high HIV prevalence rates among healthcare workers is important in planning the development of human resources. This review sought to identify and understand predominant risky sexual behaviours among healthcare workers in HIV and AIDS-affected countries. This study reviewed articles focusing on sexual behaviour among healthcare workers. Major health science databases (e.g. ProQuest, Cochrane, PubMed and CINAHL) were searched for combinations of keywords including 'healthcare workers', 'risky sexual behaviour' and 'HIV and AIDS'. Articles from a range of countries met inclusion and exclusion criteria. Findings of the study revealed three main contributing factors: unprotected sex, multiple sex partners and sexual violence. Sexual violence emerged as the dominant risk factor in the majority of the studies. Most research was conducted in developed countries where the HIV infection rate is much lower than it is in developing countries. More research needs to be conducted in developing countries and appropriate strategies should be implemented to reduce sexual violence among healthcare workers. Appropriate procedures on reporting sexual violence coupled with education on HIV and AIDS as well as influencing attitudes and belief systems could assist in reducing the spread of HIV and AIDS within the healthcare workforce while minimising the effect on patient care.

Neurological complications of human immunodeficiency virus infection.

PubMed Central

Kennedy, P. G.

1988-01-01

The protean neurological manifestations of human immunodeficiency virus (HIV) infection are reviewed. Both the central nervous system and peripheral nervous system may be affected and many of the complications may occur in individuals with acquired immunodeficiency syndrome (AIDS)-related complex, or who are seropositive for HIV alone as well as those with the established AIDS syndrome. Specific therapy is available for certain of these neurological conditions, but the clinical course in others is untreatable and progressive. Although it seems likely that the pathogenesis of some of these syndromes such as the AIDS-dementia complex are due to the direct effect of HIV on the nervous system, in others the neurological injury probably occurs as a consequence of the immunosuppression which HIV induces, or immune-mediated mechanisms.

A 35-years-old right-handed man admitted to our hospital with a worsening of dysarthria, left facial palsy and left hemiparesis for 2 days. Acquired immunodeficiency syndrome (AIDS) was diagnosed when he was 28 years old. At that time, he also was treated for syphilis. After highly active antiretroviral treatment (HAART) was introduced at the age of 35 years old, serum level of human immunodeficiency virus (HIV) was not detected, but the number of CD4+ T cells was still less than 200/μl. He had no risk factors of atherosclerosis including hypertension, diabetes and hyperlipidemia. He had neither coagulation abnormality nor autoimmune disease. Magnetic resonance imaging (MRI) showed acute ischemic infarction spreading from the right corona radiate to the right internal capsule without contrast enhancement. Stenosis and occlusion of intracranial arteries were not detected by MR angiography. Although argatroban and edaravone were administered, his neurological deficits were worsened to be difficult to walk independently. Cerebrospinal fluid (CSF) examination showed a mild mononuclear pleocytosis (16/μl).　Oligoclonal band was positive. The titer of anti-varicella zoster virus (VZV) IgG antibodies was increased, that indicated VZV reactivation in the central nervous system (CNS), although VZV DNA PCR was not detected. Therefore, acyclovir (750 mg/day for 2 weeks) and valaciclovir (3,000 mg/day for 1 month) were administered in addition to stroke therapy. He recovered to be able to walk independently 2 month after the admission.Angiography uncovered a saccular aneurysm of 3 mm at the end of branch artery of right anterior cerebral artery, Heubner artery, 28 days after the admission. We speculated that VZV vasculopathy caused by VZV reactivation in CNS was involved in the pathomechanism of cerebral infarction rather than HIV vasculopathy in the case.

The diagnosis of central nervous system toxoplasmosis was established by brain biopsy after nondiagnostic serologic and radiographic studies. At autopsy, the anterior pituitary was necrotic, with Toxoplasma abscesses in neighboring brain structures. Clinical and laboratory data met the criteria for the acquired immune deficiency syndrome. Although this is the first reported case of toxoplasmosis presenting as panhypopituitarism, future cases may be identified since central nervous system toxoplasmosis is being recognized more frequently in patients with immunodeficiency.

Objective Immunosuppression may increase risk for some skin cancers. We evaluated skin cancer epidemiology among persons with acquired immunodeficiency syndrome (AIDS). Design We linked data from population-based U.S. AIDS and cancer registries to evaluate risk of non-keratinocytic skin cancers (melanoma, Merkel cell carcinoma, and appendageal carcinomas, including sebaceous carcinoma) in 497,142 persons with AIDS. Methods Standardized incidence ratios (SIRs) were calculated to relate skin cancer risk to that in the general population. We used logistic regression to compare risk according to demographic factors, CD4 count, and a geographic index of ultraviolet radiation exposure. Results From 60 months before to 60 months after AIDS onset, persons with AIDS had elevated risks of melanoma (SIR=1.3, 95%CI 1.1-1.4, n=292 cases) and, more strongly, of Merkel cell carcinoma (SIR=11, 95%CI 6.3-17, n=17) and sebaceous carcinoma (SIR=8.1, 95%CI 3.2-17, n=7). Risk for appendageal carcinomas increased with progressive time relative to AIDS onset (p-trend=0.03). Risk of these skin cancers was higher in non-Hispanic whites than other racial/ethnic groups, and melanoma risk was highest among men who have sex with men. Melanoma risk was unrelated to CD4 count at AIDS onset (p=0.32). Risks for melanoma and appendageal carcinomas rose with increasing ultraviolet radiation exposure (p-trend<10-4 and p-trend=10-3, respectively). Conclusions Among persons with AIDS, there is a modest excess risk of melanoma which is not strongly related to immunosuppression and may relate to ultraviolet radiation exposure. In contrast, the greatly increased risks for Merkel cell and sebaceous carcinoma suggest an etiologic role for immunosuppression. PMID:19114864

Background South Africa is known to have one of the highest prevalence rates of human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) globally, with one in seven healthcare workers being HIV-positive. An HIV-positive healthcare workforce is less equipped to respond to the increasing spread of the epidemic. Objectives Assessment of the factors contributing to high HIV prevalence rates among healthcare workers is important in planning the development of human resources. This review sought to identify and understand predominant risky sexual behaviours among healthcare workers in HIV and AIDS-affected countries. Methods This study reviewed articles focusing on sexual behaviour among healthcare workers. Major health science databases (e.g. ProQuest, Cochrane, PubMed and CINAHL) were searched for combinations of keywords including ‘healthcare workers’, ‘risky sexual behaviour’ and ‘HIV and AIDS’. Articles from a range of countries met inclusion and exclusion criteria. Results Findings of the study revealed three main contributing factors: unprotected sex, multiple sex partners and sexual violence. Sexual violence emerged as the dominant risk factor in the majority of the studies. Most research was conducted in developed countries where the HIV infection rate is much lower than it is in developing countries. Conclusion More research needs to be conducted in developing countries and appropriate strategies should be implemented to reduce sexual violence among healthcare workers. Appropriate procedures on reporting sexual violence coupled with education on HIV and AIDS as well as influencing attitudes and belief systems could assist in reducing the spread of HIV and AIDS within the healthcare workforce while minimising the effect on patient care.

To respond to the human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) epidemic in China, the integration of antiretroviral therapy (ART) and traditional Chinese medicine (TCM) has important implications in health outcomes, especially in China where the use of TCM is widespread. The National Free TCM Pilot Program for HIV Infected People began in 5 provinces (Henan, Hebei, Anhui, Hubei, and Guangdong) in 2004, and quickly scaled up to 19 provinces, autonomous regions, and municipalities in China including some places with high prevalence, 26,276 adults have been treated thus far. Usually, people with HIV infection seek TCM for four main reasons: to enhance immune function, to treat symptoms, to improve quality of life, and to reduce side effects related to medications. Evidences from randomized controlled clinical trials suggested some beneficial effects of use of traditional Chinese herbal medicine for HIV infections and AIDS. More proofs from large, well-designed, rigorous trials is needed to give firm support. Challenges include interaction between herbs and antiretroviral drugs, stigma and discrimination. The Free TCM Program has made considerable progress in providing the necessary alternative care and treatment for HIV-infected people in China, and has strong government support for continued improvement and expansion, establishing and improving a work mechanism integrating Chinese and Western medicines.

Histoplasmosis is one of the most common and deadly opportunistic infections among persons living with human immunodeficiency virus (HIV)/acquired immune deficiency syndrome in Latin America, but due to limited diagnostic capacity in this region, few data on the burden and clinical characteristics of this disease exist. Between 2005 and 2009, we enrolled patients ≥ 18 years of age with suspected histoplasmosis at a hospital-based HIV clinic in Guatemala City. A case of suspected histoplasmosis was defined as a person presenting with at least three of five clinical or radiologic criteria. A confirmed case of histoplasmosis was defined as a person with a positive culture or urine antigen test for Histoplasma capsulatum . Demographic and clinical data were also collected and analyzed. Of 263 enrolled as suspected cases of histoplasmosis, 101 (38.4%) were confirmed cases. Median time to diagnosis was 15 days after presentation (interquartile range [IQR] = 5-23). Crude overall mortality was 43.6%; median survival time was 19 days (IQR = 4-69). Mycobacterial infection was diagnosed in 70 (26.6%) cases; 26 (25.7%) histoplasmosis cases were coinfected with mycobacteria. High mortality and short survival time after initial symptoms were observed in patients with histoplasmosis. Mycobacterial coinfection diagnoses were frequent, highlighting the importance of pursuing diagnoses for both diseases.

Intravenous paclitaxel, 100 mg/m(2), given over 3 hours every 2 weeks is associated with a response rate of 59% in patients with recurrent or refractory acquired immunodeficiency syndrome (AIDS)-related Kaposi sarcoma (KS). However, this regimen is associated with significant myelosuppression, and the inconvenience of a 3-hour infusion. Moreover, no effective therapies have been defined for use after treatment failure with this agent. A Phase II trial was conducted with weekly docetaxel in patients with advanced-stage KS to assess safety and antitumor activity. Docetaxel was administered at a dose of 25 mg/m(2) intravenously over 15-30 minutes weekly for 8 weeks. Thereafter, if the patient experienced stable disease or better response, treatment doses were given every other week until complete disease remission, disease progression, or unacceptable toxicity occurred. Twelve patients were accrued-9 had > 25 mucocutaneous lesions, 1 had lymphedema, and 2 had visceral involvement. Ten patients (83%) had previous systemic chemotherapy, including 4 who received previous paclitaxel. Treatment was well tolerated, with no Grade 4 toxicity of any type. Grade 3 neutropenia occurred in 33% of patients but no patient had neutropenic fever. Five patients (42%) achieved a partial response, including 1 who had previously failed to respond to paclitaxel. The median time to disease progression was 26 months (range, 5-53 months). With a median follow-up period of 45 months, the median survival point had not been reached. Weekly docetaxel is safe, with reasonable antitumor activity in patients with advanced-stage, recurrent, or refractory AIDS-related KS. (c) 2004 American Cancer Society.

Cystic fibrosis (CF) is of particular importance in Ireland as the Irish population has both the highest incidence (2.98/10,000) and the highest carrier rate (1 in 19) in the world. Primary immunodeficiency has not been previously reported as co-existing with CF. We report a unique case of CF associated with a primary immunodeficiency syndrome--common variable immunodeficiency (CVID). Our patient has CF, CVID and the additional comorbidity of Aspergers syndrome. The challenges inherent in diagnosing and treating such a case are outlined herein and the successful management of this case is evidenced by the well-preserved lung function of our patient.

The imaging characteristics of cryptococcosis in rheumatoid arthritis (RA) patients were analyzed by comparing them with those of acquired immunodeficiency syndrome (AIDS) and immunocompetent patients, and the imaging findings were correlated with pathological findings. Two radiologists retrospectively compared the computed tomographic (CT) findings of 35 episodes of pulmonary cryptococcosis in 31 patients with 3 kinds of underlying states (10 RA, 12 AIDS, 13 immunocompetent), focusing on the nature, number, and distribution of lesions. The pathological findings of 18 patients (8 RA, 2 AIDS, 8 immunocompetent) were analyzed by two pathologists, and then correlated with imaging findings. The frequencies of consolidation and ground glass attenuation (GGA) were significantly higher, and the frequency of peripheral distribution was significantly lower in the RA group than in the immunocompetent group. Peripheral distribution was less common and generalized distribution was more frequent in the RA group than in the AIDS group. The pathological findings of the AIDS and immunocompetent groups reflected their immune status: There was lack of a granuloma reaction in the AIDS group, and a complete granuloma reaction in the immunocompetent group, while the findings of the RA group varied, including a complete granuloma reaction, a loose granuloma reaction and a hyper-immune reaction. Cases with the last two pathologic findings were symptomatic and showed generalized or central distribution on CT. Cryptococcosis in the RA group showed characteristic radiological and pathological findings compared with the other 2 groups. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

To investigate the effect of a treatment course of comprehensive intervention with Traditional Chinese Medicine (TCM) on the mortality of patients with acquired immunodeficiency syndrome (AIDS) treated with combined antiretroviral therapy (cART). AIDS patients who had taken cART in a national TCM human immunodeficiency virus treatment trial program (NTCMTP) before 2009 were enrolled in this study and followed for 36 months from November 2009. Patients enrolled in the NTCMTP in 2004 were taken as the first group, those enrolled in 2006 as the second group, and those enrolled in 2009 as the third group. Cumulative survival rates were calculated by the life table method. Survival curves for subgroups were compared by the log-rank test. Hazard ratios were calculated with a Cox proportional hazards model. A total of 1443 AIDS patients were followed for 3 years (4198 person-years). During this period, 91 (6.3%) patients died and 13 (0.9%) were lost to follow-up. The total mortality rate was 2.17/ 100 person-years. The mortality rate of patients enrolled in the NTCMTP in 2004 was 1.49/100 person- years, which was lower than that of patients enrolled in 2006 (2.23/100 person-years) and 2009 (3.48/100 person-years). After adjusting for other factors, a shorter time of treatment with TCM, male sex, older age, lower CD4 + T-cell counts, and long-term treatment with cART were risk factors of mortality. Long-term treatment with TCM decreased the mortality risk of AIDS patients. Factors such as being male, older age, CD4 + T-cell counts, and time of treatment with TCM and cART were correlated with mortality.

An enlargement of the thymus suggesting a tumor was discovered in a 28-year-old man who had early-stage acquired immune deficiency syndrome. A biopsy was performed. The adipose involuted thymus, with persistence of many Hassall's corpuscles, was judged to be a large lymphoid follicular hyperplasia. This follicular hyperplasia was similar to that previously described for lymph nodes, spleen, and other lymphoid tissues at earlier stages of human immunodeficiency virus infection, before the development of acquired immune deficiency syndrome. Human immunodeficiency virus RNA and p24 human immunodeficiency virus protein were detected in the hyperplastic germinal centers (lymphocytes and follicular dendritic infected cells), and also in many cells that may have been either lymphocytes and/or epithelial cells in the interfollicular areas. The tissue was negative for Epstein-Barr virus DNA sequences, as determined by the polymerase chain reaction. These observations identify the first state of infection of the thymus in a human immune deficiency virus-infected adult, preceding the severe involution with lymphoid depletion observed in all fatal cases of acquired immunodeficiency syndrome in which the thymus has been analyzed.

Skin diseases characterize all stages of human immunodeficiency virus (HIV) infection and acquired immunodeficiency syndrome (AIDS) and contribute significantly to associated morbidity and mortality. The aim of this study was to document the prevalences, patterns, and extents (severity) of skin diseases and their relationships with immunologic status in HIV/AIDS patients. A total of 140 HIV/AIDS patients in different stages of HIV infection and 140 controls were recruited. Skin diseases were documented and CD4+ cell counts determined in all subjects. Severity was assessed according to the body surface area affected (using the Wallace rule of nines and the rule of palm) for lesions that tended to be widespread. The number of digits involved was counted for lesions involving the nails. Intensity of pain was graded for specific conditions such as herpes zoster. Chi-squared statistics and Pearson correlations were determined. Mean±standard deviation age was 35.04±8.83 years in the patient group and 32.21±8.30 years in the control group. The prevalences and patterns of skin diseases in HIV/AIDS patients were similar to those reported in previous studies. Most commonly found dermatoses were oral candidiasis (n=28, 20.0%), pruritic papular eruption (n=27, 19.3%), xeroderma (n=23, 16.4%), dermatophytosis (n=22, 15.7%), and fluffy hair (n=19, 13.6%). The presence of specific skin lesions represented a better correlate with immunosuppression than cutaneous extents. However, the extents of viral warts and multiple blue–black nails correlated significantly with CD4+ cell count. The presence of a lighter hair color phenotype signifies a lower CD4+ cell count than a softer hair phenotype. The presence of specific skin lesions correlates more strongly with a low CD4+ cell count than does the extent of their distribution, except in cases of viral warts. The presence of and higher numbers of nails affected with blue–black nail hyperpigmentation suggest severe

Colonic histoplasmosis is a rare entity. There have been four previous reported cases within the population of patients with human immunodeficiency virus (HIV) infection. Because of the increasing incidence of HIV infection within regions where histoplasmosis is endemic, this condition may become more common. Gastrointestinal histoplasmosis has protean clinical manifestations, and symptoms are often nonspecific. Any patient with HIV infection who has unexplained GI symptoms should undergo evaluation for possible histoplasmosis. Aggressive long-term amphotericin B therapy has been effective in HIV patients with histoplasmosis. Resection or diversion of symptomatic colonic strictures caused by histoplasmosis may be necessary in addition to medical therapy.

Background In persons with acquired immunodeficiency syndrome (AIDS), Cryptosporidium parvum causes a prolonged, severe diarrheal illness to which there is no effective treatment, and the risk of developing cryptosporidiosis from drinking tap water in non-outbreak settings remains uncertain. To test the hypothesis that drinking tap water was associated with developing cryptosporidiosis, we conducted a matched case-control study among persons with AIDS in San Francisco. Methods Among patients reported to the San Francisco AIDS Registry from May 1996 through September 1998, we compared patients who developed cryptosporidiosis to those who did not. Cases were individually matched to controls based on age, sex, race/ethnicity, CD4+ T lymphocyte count, date of CD4+ count, and date of case diagnosis. Population attributable fractions (PAFs) were calculated. Results The study consisted of 49 cases and 99 matched controls. In the multivariable analysis with adjustments for confounders, tap water consumption inside and outside the home at the highest exposure categories was associated with the occurrence of cryptosporidiosis (inside the home: odds ratio (OR), 6.76; 95% CI 1.37–33.5, and outside the home: OR 3.16; 95% CI 1.23–8.13). The PAF was 85%; that is, the proportion of cases of cryptosporidiosis in San Francisco AIDS patients attributable to tap water consumption could have been as high as 85%. Conclusions Although the results from this observational study cannot be considered definitive, until there is more data, we recommend persons with AIDS, especially those with compromised immune systems, consider avoiding tap water.

Cross-sectional and descriptive study carried out from January to December, 2015, in the outpatient care of infectious disease unit in a hospital located in Fortaleza, Ceará. Data were collected through a form applied by interview in a private setting. 102 women participated in the study. Most were aware that they were serologically positive with human immunodeficiency virus (HIV) during prenatal care (96.1%) and did not intend to have more children (63.7%). Women who were less than 39 years of age, had a higher educational level, and a shorter time of antiretroviral therapy had better chances of having children (p≤0.05). Having a steady partner increased the chance of desiring to have children, while tubal ligation was higher among women that did not receive counseling on family planning. Knowledge of family planning was limited because of lack of assistance provided by health professionals.

The global polio eradication program recommends the use of massive vaccination campaigns with live vaccine through National Immunization Days (NIDs) to displace the wild virus from the community. Immunodeficient patients may be indirectly infected and become chronic excretors and potential reservoirs of polioviruses, a concern for the posteradication era. This prospective study aimed to assess the risk of community-acquired infection of immunodeficient patients following NIDs, the dynamics of viral excretion and the genetic variation of excreted viruses. Sixteen children with various primary immunodeficiencies, who did not receive the vaccine during the campaign, were investigated. Stool samples were collected weekly, shortly after the NIDs, during at least 3 months, and were processed for viral isolation. Isolates were characterized by three intratypic differentiation methods and partial sequencing of the VP1/2A region. Polioviruses were detected in 4 out of 16 patients (serotype 1 in 3 patients and serotype 3 in 1 patient). Sequencing revealed more than 99% homology with homotypic Sabin strains, suggesting recent infection. Duration of viral excretion ranged from 1 to 7 weeks. Nine out of eleven isolates from the three poliovirus serotype 1-infected patients disclosed a non-Sabin-like phenotype by enzyme-linked immunosorbent assay and had recurrent mutations within or close to the neutralizing antigenic sites. In summary, the risk of secondary infection in immunodeficient patients is within the range previously reported for the general population. Although none of the four infected patients developed prolonged viral excretion, particular viral variants were selected and may be of epidemiological significance. PMID:12624052

The clinical data, histologic findings, and computed tomographic (CT) abnormalities in eight adult Haitians with toxoplasma encephalitis were analyzed retrospectively. Diagnosis was established by identification of Toxoplasma gondii on autopsy in five and brain biopsy in three specimens and subsequently confirmed by the immunoperoxidase method. All these patiens, six of whom had been in the United States for 24 months or less, had severe idiopathic immunodeficiency syndrome. All were lymphopenic and six were on treatment for tuberculosis when the toxoplasma encephalitis developed. All patients were studied with CT when they developed an altered mental status and fever associated with seizuresmore » and/or focal neurologic deficits. Scans before treatment showed multiple intraparenchymal lesions in seven and a single lesion in the thalamus in one. Ring and/or nodular enhancement of the lesions was found in six and hypodense areas in two. Progressions of abnormalities occurred on serial studies. These CT findings that were best shown on axial and coronal thin-section double-dose contrast studies were useful but not diagnostically pathognomonic. In patients with similar clinical presentation CT is recommended to identify focal areas of involvement and to guide brain biopsy or excision so that prompt medical thereapy of this often lethal infection can be instituted.« less

A 66-year-old man, who was discovered to have human immunodeficiency virus (HIV) infection 22 months previously and was treated with highly active antiretroviral (HAART) therapy, developed giant cell carcinoma of the lung. In English literature, this is the first case of such cell type of lung cancer during HAART therapy. Since giant cell carcinoma of the lung occurs mainly in elderly men who smoke heavily, there may not be a possibility that the HIV or HAART was causative in our patient.

A simple methodology for estimating HI\\'-related Medicaid costs under alternative assumptions about the future is also explained. PMID:10113503

Acquired immunodeficiency syndrome — an assessment of the present situation in the world: Memorandum from a WHO Meeting*

PubMed Central

1984-01-01

A consultative meeting was convened by the World Health Organization in Geneva on 22-25 November 1983 to assess the present situation of AIDS (the acquired immunodeficiency syndrome) in the world and to encourage collaboration between the different nations affected by this disease. AIDS was first reported in the USA in 1981, but probably existed there as early as 1978. Soon after its recognition in the USA, similar cases were identified in other areas of the world. In most western European countries and Canada, the epidemiological pattern is very similar to that in the United States, the majority of cases being in homosexual men. In other areas such as equatorial Africa and the Caribbean, the pattern seems to be different with no identifiable risk factors for the majority of cases. The disease is manifested by opportunistic infections and/or selected malignancies, with apparent differences in the clinical presentation between the cases in North America and Europe, on the one hand, and those in the tropics. To date there is no treatment that has significantly improved the underlying cellular immune deficiency, and the mortality is very high. The etiology of AIDS is unknown, but the epidemiological pattern is most consistent with its being caused by a transmissible agent; retroviruses come on top of the list of candidate agents. Despite the unknown etiology and the lack of laboratory diagnostic tests, sufficient information is available to permit health authorities to make recommendations that may reduce appreciably the incidence of the disease. AIDS is an important health problem in a number of countries and has international implications. Collaborative laboratory, epidemiological and clinical research between countries is needed to accelerate control efforts. In the meantime, WHO will coordinate exchange of information among countries. ImagesFig. 1 PMID:6331905

Serum galactomannan levels of penicilliosis patients and AIDS patients with fever were measured by the Platelia Aspergillus Enzyme Immunoassay Kit. A total of 47 AIDS-associated penicilliosis were confirmed by fungal culture, which accounted for 4.8% of 981 AIDS-related admissions. The sensitivity and specificity of serum galactomannan test for penicilliosis were 95.8% (23/24) and 90.9% (30/33), respectively, (cutoff index = 1.0). Two independent predictors for early mortality (death within 12 weeks) of the patients (21.3%, 10/47) were a delayed diagnosis and no treatment with antifungal therapy. Among 14 patients who became ill after leaving endemic areas, ten patients presented with the onset symptoms within 12 months (from 11 days to 360 days). We found a patient living with asymptomatic P. marneffei fungemia who had not received any antifungal therapy until 18 months' follow up. The co-infection of P. marneffei and HIV was not uncommon in the non-endemic areas of penicilliosis in China. There exists a latent form of infection for P. marneffei. The incubation period of penicilliosis may be quite different from one patient to another. In AIDS patients, the serum galactomannan test has utility for the diagnosis of penicilliosis. When patients with penicilliosis/AIDS were diagnosed early and treated with standardized antifungal therapy and combined antiretroviral therapy, their prognosis improved.

The number of acquired immunodeficiency syndrome (AIDS)-related deaths covers different segments of the population differently, making monitoring of this mortality essential. The aim of this study was to describe the epidemiological situation of AIDS-related mortality in a municipality in the northeastern region of Brazil. Retrospective cross-sectional study based on data from death certificates in the mortality information system of the Health Information Center, Municipal Health Foundation, Brazil. Between 2003 and 2013, we investigated death certificates on which AIDS-related mortality was reported. Sociodemographic data, year, place, type of establishment where death occurred and underlying and associated causes that led to AIDS-related death were described. The Mann-Kendall test was used to verify the growth trend of the standardized mortality rate over the period studied. Among the 1,066 AIDS-related deaths, 69.7% were among men; 47.2% of the individuals were 28-41 years of age, 32.7% had had 4-7 years of schooling, 66.9% were pardos (mixed race), 55.7% were unmarried and 15.3% were housekeepers. Hospitals were the site of 97% of the deaths, and 91% occurred at public hospitals. Respiratory failure was the main cause of death. The prevalence of infectious and parasitic diseases was 99.0%. AIDS-related mortality increased by 160% over the period studied, from 5.5/100,000 inhabitants in 2003 to 14.3/100,000 in 2013. In the Brazilian municipality studied here, AIDS-related mortality was most prevalent among men and young adults of lower socioeconomic level. Over the period studied, the mortality rate increased.

To systematically review the efficacy and safety of Traditional Chinese Medicine (TCM) interventions, compared with control interventions (placebo or conventional Western medical therapy), in the treatment of acquired immunodeficiency syndrome (AIDS). Electronic databases including PubMed, the Cochrane Library, China National Knowledge Infrastructure (CNKI), and Wanfang Data were searched to identify relevant randomized controlled trials (RCTs) published as of May 2012. Studies were selected according to the specified inclusion and exclusion criteria and then subjected to methodological quality assessment, data extraction, and meta-analysis according to the Cochrane Handbook for Systematic Reviews of Interventions. Twelve RCTs involving 881 patients with AIDS were included. Methodological quality assessment showed that two were high-quality, two were moderate-quality, and eight were low-quality. Meta-analysis showed that TCM interventions were associated with significantly reduced plasma viral load compared with placebo [odds ratio OR = 2.46, 95% confidence interval CI (1.02, 5.94); P = 0.04]. However, the reductions in plasma viral load significantly favored conventional Western medical therapy alone over integrated traditional Chinese and Western medical therapy [OR = 0.16, 95% CI (0.05, 0.55); P = 0.004]. Patients receiving TCM interventions had significantly higher CD4+ T lymphocyte counts compared with those on placebo [OR = 2.54, 95% CI (1.40, 4.60); P = 0.002]. In addition, TCM interventions were significantly more likely to have improved clinical symptoms [OR = 2.82, 95% CI (1.85, 4.31); P < 0.00001]. TCM interventions conferred a similar risk of adverse events (AEs) compared with control interventions [OR = 1.87, 95% CI (0.58, 6.01); P = 0.29]. Current evidence suggests that TCM interventions are significantly more effective than placebo in reducing plasma viral load and increasing CD4+ T lymphocyte count in patients with AIDS.

Objectives Patients with the acquired immunodeficiency syndrome (AIDS) have an abnormality of retina/optic nerve function, manifested as decreased contrast sensitivity (in the absence of ocular opportunistic infections or media opacity), abnormalities on automated perimetry, and loss of retinal nerve fiber layer, even among those with good visual acuity, termed the HIV-neuroretinal disorder. The objectives of this study were to determine the prevalence, incidence, risk factors for, and outcomes of HIV-neuroretinal disorder. Design Prospective cohort study Participants 1822 patients with AIDS without ocular infections or media opacities. Methods Patients with HIV-neuroretinal disorder were identified by a contrast sensitivity < 1.50 log units in either eye in the absence of ocular opportunistic infections or media opacity. Main outcome measures Incidence of HIV-neuroretinal disorder, mortality, visual impairment (visual acuity 20/50 or worse), and blindness (20/200 or worse) on logarithmic visual acuity charts. Results Sixteen percent of participants had HIV-neuroretinal disorder at enrollment. The estimated cumulative incidence by 20 years after AIDS diagnosis was 51% (95% confidence interval [CI] 46%–55%). HIV-neuroretinal disorder was more common in women and African American persons. Risk factors for it included hepatitis C infection, low CD4+ T cells, and detectable HIV RNA in the blood. Patients with HIV neuroretinal disorder had a 70% excess mortality vs. those without it, even after adjusting for CD4+ T cells and HIV load (hazard ratio=1.7, 95% CI= 1.3–2.1, P<0.0001). Patients with HIV-neuroretinal disorder had increased risks of bilateral visual impairment (hazard ratio=6.5, 95% CI=2.6–10.6, P<0.0001) and blindness (hazard ratio=5.9, 95% CI=2.8–13.7, P=0.01) vs. those without HIV neuroretinal disorder. Conclusions HIV-neuroretinal disorder is a common finding among patients with AIDS, and it is associated with an increased mortality and an increased

To investigate the clinical characteristics of cytomegalovirus retinitis (CMVR) in acquired immunodeficiency syndrome (AIDS) patients. Retrospective case-series study. The clinical and laboratory data of 80 AIDS patients (118 eyes) with findings of CMVR were collected from Shanghai Public Health Clinical Center from December 2006 to December 2011. The relationship between CMVR and cellular immunity, the high risk factor, clinical characteristics, treatment and prognosis of CMVR were analyzed in this study. χ(2) test was used to check the incidence of CMVR in different CD4(+) T lymphocyte count groups. There was 80 AIDS patients (118 eyes) totally, 71 males and 9 females. Their age was from 18 to 60 years old, which mean value was (38 ± 10) years old. The incidence in the group of CD4(+) T lymphocyte count over 100 cells/µl was lower than the two groups of CD4(+) T lymphocyte count less than 100 cells/µl (χ(2) = 15.567, 32.469; P = 0.00,0.00). CD4(+) T lymphocyte count was always ranged from 0 to 141 cells/µl in CMVR patients. It was less than 50 cells/µl in 81.3% cases. In 10.0% AIDS patients, CMVR was the first manifestation. In 25% AIDS patients(26 eyes), lesions in retina was found by routine eye examination. In 54.2% patients, the best corrected visual acuity was less than 0.3. Retinal necrosis was involvement near the posterior pole in 62.5% CMVR patients. The visual acuity of 51 eyes was improved after treatment within 94.1% cases which were treated within 3 months. However, BCVA of 35 eyes decreased or with less change within 42.9% cases which were treated after symptoms appeared 3 months. The anti-CMV treatment included induction and maintenance of ganciclovir or foscarnet stopped when the CD4(+)T lymphocyte count was more than 150 cells/µl in 3 continuous months. 86.9% eyes were cured clinically. Retinal detachment, immune reconstitution uveitis and complicated cataract was found in 13.1%, 12.1% and 20.5% cases respectively. Optic atrophy occurred

Human immunodeficiency virus seroprevalence in an occupational cohort in a South African community.

In the early years of the worldwide pandemic, there were no reported cases of acquired immunodeficiency syndrome in Lesotho, a small, mountainous country in South Africa. Since 1986, when the first case of acquired immunodeficiency syndrome was identified, reported diagnoses have risen precipitously. The initiation of the Lesotho Highlands Water Project has resulted in the influx of a migrant workforce of predominantly single males into a relatively isolated, mountainous area where human immunodeficiency virus (HIV) was previously unknown. To ascertain the HIV seroprevalence among a cohort of laborers at the Katse Dam construction site in Bokong, Lesotho. During the 5-week study period in late 1992, construction workers (age range, 15 to 59 years) who were first-time clinic users for any chief complaint were randomly selected for serological study. Surveillance complied with the Lesotho National AIDS Control Programme guidelines, which required unlinked, anonymous testing. Serum samples were screened by an enzyme-linked immunosorbent assay; the results were confirmed by the Western blot technique. Unlinked, anonymous HIV testing of 486 persons revealed a seroprevalence of 5.3% (26/486; 95% confidence interval, 3.3% to 7.3%). These data contrasted with a 0.8% seroprevalence in a similar age group in nearby villages that surrounded the construction project. Lesotho, in the early phase of the HIV/acquired immunodeficiency syndrome epidemic in Africa in the 1980s, was seemingly protected by its relative isolation. Grave concern is now warranted as the country is destined to experience a rapid rise in HIV seroprevalence. Increased surveillance, health education opportunities, and aggressive prevention activities at the Katse Dam construction site are imperative to arrest the spread of HIV from construction workers to nearby villagers.

To investigate the traditional Chinese Medicine (TCM) etiology and pathogenesis of acquired immune deficiency syndrome (AIDS) by 18-month observation of Chinese rhesus macaques infected with simian immunodeficiency virus (SIV) mac239. Thirty-five healthy Chinese rhesus macaques were divided into a model group (n = 30) and a control group (n = 5). The model was established by inoculating monkeys intravenously with SIVmac239. Changes in TCM symptoms after SIV infection within 18 months were then observed and recorded. Routine blood tests, SIV viral load, T-lymphocyte subsets, plasma triiodothyronine (T3), tetraiodothyronine (T4), adrenocorticotropic hormone (ACTH) and cortisol (Cor) were tested periodically during the experiment. During the acute infection period of SIV, model monkeys temporarily showed clinical symptoms such as diarrhea, dysphoria and slight weight loss. Decrease percentages of CD4+ T-lymphocytes were observed but levels of T3, T4, Cor, and ACTH were relatively unchanged. Monkeys in the model group during the early and middle periods of infection showed no obvious symptoms, except few monkeys exhibited transient diarrhea and reduced food intake. All variables at this stage showed normal fluctuations. In the middle period model group monkeys showed chronic and persistent diarrhea, weight loss, reduced food intake and low levels of T3 and Cor. In the late period, symptoms including emaciation, weight loss, listlessness, crouching in corners and low levels of T3 appeared. The results suggest that the rhesus monkey SIV/SAIDS model can be applied to research on TCM etiology and pathogenesis of AIDS. According to this model, the etiology of disease is the SIV virus. The pathogenesis manifests as the invasion of SIV virus, incubation of the virus, balance between virus and healthy "Qi", damage to spleen and kidney as the disease progressed, exhaustion of vitality and finally the failure of five zang and six fu organs.

Research studies, review articles, and books related to pain in persons with HIV/AIDS. Pain is a common problem for individuals with HIV/AIDS that is often poorly managed and net well documented. Many of these patients have multiple, coexisting illnesses that are painful. Adequate assessment of the underlying cause will help in the treatment or eradication of pain. The management of pain in persons with HIV/AIDS is an important responsibility for oncology nurses because increasing numbers of persons with HIV/AIDS are being treated for neoplastic complications, cytopenias, or being referred to hospice care.

Clinical aspects of feline immunodeficiency and feline leukemia virus infection.

Feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) are retroviruses with a global impact on the health of domestic cats. The two viruses differ in their potential to cause disease. FIV can cause an acquired immunodeficiency syndrome that increases the risk of developing opportunistic infections, neurological diseases, and tumors. In most naturally infected cats, however, FIV itself does not cause severe clinical signs, and FIV-infected cats may live many years without any health problems. FeLV is more pathogenic, and was long considered to be responsible for more clinical syndromes than any other agent in cats. FeLV can cause tumors (mainly lymphoma), bone marrow suppression syndromes (mainly anemia) and lead to secondary infectious diseases caused by suppressive effects of the virus on bone marrow and the immune system. Today, FeLV is less important as a deadly infectious agent as in the last 20 years prevalence has been decreasing in most countries. Copyright © 2011 Elsevier B.V. All rights reserved.

We assessed non-liver-related non-acquired immunodeficiency syndrome (AIDS)-related (NLR-NAR) events and mortality in a cohort of human immunodeficiency virus (HIV)/hepatitis C virus (HCV)-coinfected patients treated with interferon (IFN) and ribavirin (RBV), between 2000 and 2008. The censoring date was May 31, 2014. Cox regression analysis was performed to assess the adjusted hazard rate (HR) of overall death in responders and nonresponders. Fine and Gray regression analysis was conducted to determine the adjusted subhazard rate (sHR) of NLR deaths and NLR-NAR events considering death as the competing risk. The NLR-NAR events analyzed included diabetes mellitus, chronic renal failure, cardiovascular events, NLR-NAR cancer, bone events, and non-AIDS-related infections. The variables for adjustment were age, sex, past AIDS, HIV transmission category, nadir CD4 + T-cell count, antiretroviral therapy, HIV RNA, liver fibrosis, HCV genotype, and exposure to specific anti-HIV drugs. Of the 1,625 patients included, 592 (36%) had a sustained viral response (SVR). After a median 5-year follow-up, SVR was found to be associated with a significant decrease in the hazard of diabetes mellitus (sHR, 0.57; 95% confidence interval [CI], 0.35-0.93; P = 0.024) and decline in the hazard of chronic renal failure close to the threshold of significance (sHR, 0.43; 95% CI, 0.17-1.09; P = 0.075). Our data suggest that eradication of HCV in coinfected patients is associated not only with a reduction in the frequency of death, HIV progression, and liver-related events, but also with a reduced hazard of diabetes mellitus and possibly of chronic renal failure. These findings argue for the prescription of HCV therapy in coinfected patients regardless of fibrosis stage. (Hepatology 2017;66:344-356). © 2017 The Authors.

To retrospectively study the prevalence of fatigue and factors associated with fatigue among acquired immunodeficiency syndrome (AIDS) patients with antiretroviral drug adverse reactions. Data were collected from case report forms (CRFs) for a project funded by the 11th National 5-year Special Science and Technology Program on Major Infectious Diseases. Fatigue was defined by patient self-report. The outcomes were the prevalence of fatigue and the potential risk factors of fatigue. Univariate and multivariate logistic regression analyses were conducted to identify the factors associated with fatigue. Among the 228 subjects, the prevalence of fatigue was 86.8%. In univariate analysis, the significant differences in demographic characteristics between patients with and without fatigue were: gender [OR = 2.29; 95% CI (1.05-4.98)], education level [OR = 0.40; 95% CI (0.18-0.85)], anemia [OR = 3.80; 95% CI (1.27-11.31)], time of HIV diagnosis [OR = 0.29; 95% CI (0.13-0.65)], and route of infection [OR = 0.14; 95% CI (0.06-0.32)]. Abnormal taste and rapid pulse were more commonly seen in patients with fatigue (P < 0.05), while abdominal distension and lumbar soreness were encountered less often in patients with fatigue (P < 0.05). Multivariate analysis showed that the four main factors associated with fatigue were anemia [OR = 3.50; 95% CI (1.01-12.15)], route of infection [OR = 3.40; 95% CI (1.21-9.58); P = 0.02 < 0.05], lumbar soreness [OR = 0.06; 95% CI (0.02-0.18); P = 0.000 < 0.05], and rapid pulse [OR = 10.58; 95% CI (2.16-51.75); P = 0.004 < 0.05]. This study demonstrated that fatigue is common (86.8% prevalence) in AIDS patients with antiretroviral drug adverse reactions, and that anemia, route of infection (i.e., non-commercial blood donation) and rapid pulse were risk factors, while lumbar soreness was a protective factor related to fatigue. More attention should be paid to fatigue and more efforts should be made to find ways to prevent, control and eliminate

A 40-year-old female, HIV positive, stage C, since 4 years, complained of a right cervical lymph node swelling. Two years before, the patient had been diagnosed with follicular B-cell non-Hodgkin lymphoma (FL); she had been treated with four cycles of multiagent chemotherapy plus rituximab, the last cycle being administered 10 months before coming to our attention. An ultrasound (US) guided fine-needle cytology (FNC) showed an atypical lymphoid cell proliferation. The phenotype evidenced by flow cytometry (FC) analysis was D5: 10%, CD19: 49%, CD23: 10%, FMC7: 0%, CD10: 40%, CD10/19: 40%, lambda light chain 40%, kappa light chain 0%. FDG-positron emission tomography (PET/CT) scan showed positivity in the corresponding cervical area. Since low LDH values and a reduced lymph node size were observed, the lymph node was therefore excised; the histology revealed a reactive hyperplastic lymph node with florid follicular pattern. A subsequent PCR analysis, performed on DNA extracted from a whole histological section, did not evidence IgH rearrangement. The patient is currently undergoing strict clinical and instrumental follow-up, including PET every 3 months; after 13 months, she is alive without recurrence of lymphoma. Clonal B-cell populations in non-lymphomatous processes have been described in mucosa-associated lymphoid cell populations and reactive lymph nodes, and are considered non-malignant, antigen driven, proliferations of B-lymphocytes determined by an abnormal response to bacterial or viral antigen stimulation. The present case occurred in an HIV patient and was clinically complex because of the patient's history of FL. This experience suggests much attention in the evaluation of radiological, cytological, and FC data and in clinical correlation in patients suffering from autoimmune or immunodeficiency syndromes.

Acquired immune deficiency syndrome (AIDS) is an immune deficiency disease. The etiology of hyperthyroidism, which can also be immune-related, is usually divided into six classical categories, including hypophyseal, hypothalamic, thyroid, neoplastic, autoimmune and inflammatory hyperthyroidism. Hyperthyroidism is a rare complication of highly active antimicrobial therapy (HAART) for human immunodeficiency virus (HIV). Hyperthyroidism caused directly by AIDS has not been previously reported. A 29-year-old man who complained of dyspnea and asthenia for 1 month, recurrent fever for more than 20 days, and breathlessness for 1 week was admitted to our hospital. The thyroid function test showed that the level of free thyroxine (FT4) was higher than normal and that the level of thyroid-stimulating hormone (TSH) was below normal. He was diagnosed with hyperthyroidism. Additional investigations revealed a low serum albumin level and chest infection, along with diffuse lung fibrosis. Within 1 month, he experienced significant weight loss, no hand tremors, intolerance of heat, and perspiration proneness. We recommended an HIV examination; subsequently, AIDS was diagnosed based on the laboratory parameters. This is the first reported case of hyperthyroidism caused by AIDS. AIDS may cause hyperthyroidism by immunization regulation with complex, atypical, and easily ignored symptoms. Although hyperthyroidism is rare in patients with AIDS, clinicians should be aware of this potential interaction and should carefully monitor thyroid function in HIV-positive patients.

Stigma and discrimination attached to human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) have been recognised as a major obstacle to HIV prevention, treatment, care and support throughout the world. Stigma and discrimination are more devastating when they occur in health care settings where it is least expected. To explore the factors attributable to stigma and discrimination of people living with HIV in two Ethiopian rural hospitals on what they thought of health care professionals (HCPs) attending to them. A qualitative exploratory approach was used. Data collection was by means of audio-taped interview and Tesch's content analysis approach was used. The sample size for this study was determined by saturation of data and consisted of 16 participants who were people living with HIV admitted as inpatients to the two selected hospitals in Amhara region of Ethiopia. Participants' views were grouped into: fear of contact, delay of services, substandard services, denial of care, impoliteness of health care providers, breach of confidentiality and poor patient follow-up for persons infected with HIV. The health care settings have been recognised as one of the contexts where HIV and AIDS-related stigmatisation and discrimination can occur. Hospital policies and institutional support should be tailored to embrace people living with HIV as the provision of institutional support is imperative in creating a good working environment and improving the commitment of HCPs so as to enable them to provide holistic care for people living with HIV and AIDS (PLWHA) without discrimination.

Background Ectodermal dysplasia (ED) syndromes are a diverse group of disorders that affect multiple ectodermally derived tissues. Small studies and case reports suggest an increase in atopy and primary immunodeficiencies (PIDs) among patients with ED syndromes. Objective To determine the prevalence of clinical symptoms suggestive of atopy or immunodeficiency among a large cohort of children with ED syndromes. Methods A 9-page questionnaire was mailed to families who were members of the National Foundation for Ectodermal Dysplasias. The surveys were completed by parents of children younger than 18 years with a diagnosis of an ED syndrome or carrier state. Portions of the questionnaire were adapted from previously validated questionnaires developed by the International Study of Asthma and Allergies in Childhood (ISAAC). Results We received 347 completed questionnaires (41%). When compared with the 13- to 14-year-old children surveyed by ISAAC, we found both all-aged and age-matched children with ED syndromes, respectively, had significantly higher rates of asthma (32.2% and 37.2% vs 16.4%), rhinitis symptoms (76.1% and 78.3% vs 38.9%), and eczema (58.9% and 48.9% vs 8.2%). The prevalence of physician-diagnosed food allergies (20.7%) and PIDs (6.1%) in these ED patients also exceeded known rates in the general pediatric population. Conclusion This large-scale, retrospective study demonstrates a greater reported prevalence of symptoms suggestive of atopic disorders and PIDs among children with ED syndromes than the general pediatric population. A combination of genetic and environmental factors in ED syndromes may contribute to breaches of skin and mucosal barriers, permitting enhanced transmission and sensitization to irritants, allergens, and pathogens.

The acquired immunodeficiency syndrome-related complex was identified in a mother and one of her nonidentical twins. Generalized lymphadenopathy was first noted in the infant at age 17 months, and that of the mother was incidentally discovered 6 months later. The father, who had had homosexual contacts before the conception of the twins, appeared to be in good health. No one in the family had constitutional symptoms or showed signs of opportunistic infection. Both parents and the patient had hypergammaglobulinemia, low T-helper-to-suppressor-cell ratio, and positive serum antibody to human immunodeficiency virus. Attempts to isolate the virus from all family members were unsuccessful. The twin brother was in good health with a normal immunologic profile and negative antibody to human immunodeficiency virus.

DiGeorge syndrome, or velocardiofacial syndrome (DGS/VCFS), is a rare and usually sporadic congenital genetic disorder resulting from a constitutional microdeletion at chromosome 22q11.2. While rare cases of malignancy have been described, likely due to underlying immunodeficiency, central nervous system tumors have not yet been reported. We describe an adolescent boy with DGS/VCFS who developed a temporal lobe pleomorphic xanthoastrocytoma. High-resolution single nucleotide polymorphism array studies of the tumor confirmed a constitutional 22q11.21 deletion, and revealed acquired gains, losses and copy number neutral loss of heterozygosity of several chromosomal regions, including a homozygous deletion of the CDKN2A/B locus. The tumor also demonstrated a common V600E mutation in the BRAF oncogene. This is the first reported case of a patient with DiGeorge syndrome developing a CNS tumor of any histology and expands our knowledge about low-grade CNS tumor molecular genetics.

Virus-host interaction in feline immunodeficiency virus (FIV) infection.

Feline immunodeficiency virus (FIV) infection has been the focus of several studies because this virus exhibits genetic and pathogenic characteristics that are similar to those of the human immunodeficiency virus (HIV). FIV causes acquired immunodeficiency syndrome (AIDS) in cats, nevertheless, a large fraction of infected cats remain asymptomatic throughout life despite of persistent chronic infection. This slow disease progression may be due to the presence of factors that are involved in the natural resistance to infection and the immune response that is mounted by the animals, as well as due to the adaptation of the virus to the host. Therefore, the study of virus-host interaction is essential to the understanding of the different patterns of disease course and the virus persistence in the host, and to help with the development of effective vaccines and perhaps the cure of FIV and HIV infections.

Acquired immunodeficiency syndrome (AIDS)-related non-Hodgkin lymphoma (NHL) constitutes an aggressive variety of lymphomas characterized by increased extranodal involvement, relapse rate, and resistance to chemotherapy. Protein kinase C-beta (PKCβ) targeting showed promising results in preclinical and clinical studies involving a wide variety of cancers, but studies describing the role of PKCβ in AIDS-NHL are primitive if not lacking. In the present study, 3 AIDS-NHL cell lines were examined: 2F7 (AIDS-Burkitt lymphoma), BCBL-1 (AIDS-primary effusion lymphoma), and UMCL01-101 (AIDS-diffuse large B-cell lymphoma). Immunoblot analysis demonstrated expression of PKCβ1 and PKCβ2 in 2F7 and UMCL01-101 cells, and PKCβ1 alone in BCBL-1 cells. The viability of 2F7 and BCBL-1 cells decreased significantly in the presence of PKCβ-selective inhibitor at half-maximal inhibitory concentration of 14 and 15 μmol/L, respectively, as measured by tetrazolium dye reduction assay. In contrast, UMCL01-101 cells were relatively resistant. As determined using flow cytometric deoxynucleotidyl transferase dUTP nick-end labeling assay with propidium iodide staining, the responsiveness of sensitive cells was associated with apoptotic induction and cell cycle inhibition. Protein kinase C-beta-selective inhibition was observed not to affect AKT phosphorylation but to induce a rapid and sustained reduction in the phosphorylation of glycogen synthase kinase-3 beta, ribosomal protein S6, and mammalian target of rapamycin in sensitive cell lines. The results indicate that PKCβ plays an important role in AIDS-related NHL survival and suggest that PKCβ targeting should be considered in a broader spectrum of NHL. The observations in BCBL-1 were unexpected in the absence of PKCβ2 expression and implicate PKCβ1 as a regulator in those cells.

Histoplasmosis is common among persons living with human immunodeficiency virus/acquired immune deficiency syndrome (PLWHA) in Latin America, but its diagnosis is difficult and often nonspecific. We conducted prospective screening for histoplasmosis among PLWHA with signs or symptoms suggesting progressive disseminated histoplasmosis (PDH) and hospitalized in Hospital La María in Medellín, Colombia. The study's aim was to obtain a clinical and laboratory profile of PLWHA with PDH. During 3 years (May 2008 to August 2011), we identified 89 PLWHA hospitalized with symptoms suggestive of PDH, of whom 45 (51%) had histoplasmosis. We observed tuberculosis (TB) coinfection in a large proportion of patients with PDH (35%), so all analyses were performed adjusting for this coinfection and, alternatively, excluding histoplasmosis patients with TB. Results showed that the patients with PDH were more likely to have Karnofsky score ≤ 30 (prevalence ratio [PR] = 1.98, 95% confidence interval [CI] = 0.97-4.06), liver compromised with hepatomegaly and/or splenomegaly (PR = 1.77, CI = 1.03-3.06) and elevation in serum of alanine aminotransferase and aspartate aminotransferase to values > 40 mU/mL (PR = 2.06, CI = 1.09-3.88 and PR = 1.53, CI = 0.99-2.35, respectively). Using multiple correspondence analyses, we identified in patients with PDH a profile characterized by the presence of constitutional symptoms, namely weight loss and Karnofsky classification ≤ 30, gastrointestinal manifestations with alteration of liver enzymes and hepatosplenomegaly and/or splenomegaly, skin lesions, and hematological alterations. Study of the profiles is no substitute for laboratory diagnostics, but identifying clinical and laboratory indicators of PLWHA with PDH should allow development of strategies for reducing the time to diagnosis and thus mortality caused by Histoplasma capsulatum. © The American Society of Tropical Medicine and Hygiene.

In last fifteen years remarkable success in the fight against human immunodeficiency virus (HIV) is achieved globally. The number of HIV infections has decreased and the number of people on antiretroviral therapy is increased. This all is possible by strong political commitments and heavy investments in the fight against HIV. Pakistan is among few Asian countries in which HIV cases are increasing year by year since 1990. There are 94000 cases of HIV in Pakistan and only 14000 are registered with government. The main source of HIV infection in Pakistan is the use of contaminated injection equipment among people who inject drugs (PWID). The overall prevalence of HIV among PWID in Pakistan is 27.2%. There are five cities in Pakistan in which HIV prevalence is above 40% in PWIDs. In June 2016, United Nations political declaration on acquired immune deficiency syndrome (AIDS) provided a global mandate to fast-track the AIDS response over the next five years to achieve the targets in Sustainable Development Goals. To achieve the targets in fast-track AIDS response, the global leaders showed strong commitments to invest $ 26 billion per year by 2020. Pakistan needs to speed up its HIV control program. There is a dire need to locate all HIV positive people and enroll them in the treatment program. Pakistan also needs to calculate exact number of people living with HIV, increase HIV treatment centers and increase HIV awareness. Recently, Global Fund invested handsome money in the fight against HIV. Let's hope the country will have effective HIV control strategy to achieve the HIV elimination target by 2030.

Twenty different target sites within human immunodeficiency virus (HIV) RNA were selected for studies of inhibition of HIV replication by antisense oligonucleotides. Target sites were selected based on their potential capacity to block recognition functions during viral replication. Antisense oligomers complementary to sites within or near the sequence repeated at the ends of retrovirus RNA (R region) and to certain splice sites were most effective. The effect of antisense oligomer length on inhibiting virus replication was also investigated, and preliminary toxicity studies in mice show that these compounds are toxic only at high levels. The results indicate potential usefulness for these oligomers in the treatment of patients with acquired immunodeficiency syndrome (AIDS) and AIDS-related complex either alone or in combination with other drugs.

Diarrhea is one of the most common symptoms in common variable immunodeficiency, but neurologic manifestations are rare. We presented a 50-year-old woman with recurrent diarrhea and severe weight loss that developed a posterior cord syndrome. Endoscopy found a duodenal villous blunting, intraepithelial lymphocytosis, and lack of plasma cells and magnetic resonance imaging of the spine was normal. Laboratory assays confirmed common variable immunodeficiency syndrome and showed low levels of trace elements (copper and zinc). Treatment was initiated with parenteral replacement of trace elements and intravenous human immunoglobulin and the patient improved clinically. In conclusion, physicians must be aware that gastrointestinal and neurologic disorders may be related to each other and remember to request trace elements laboratory assessment. PMID:28356913

Oral health care of patients with human immunodeficiency virus (HIV)/acquired immune-deficiency syndrome (AIDS) is a growing area of concern. Information on HIV- and AIDS-related knowledge among dental students provides a crucial foundation for efforts aimed at developing an appropriate dental curriculum on HIV and AIDS. The purpose of this study was to assess the knowledge and attitude of Indian clinical dental students towards the treatment of patients with HIV/AIDS and perceived sources of information regarding HIV-related issues. Data were collected from clinical dental students (third year, fourth year and internship) from three dental institutions in Delhi National Capital Region (NCR). The questions assessed the knowledge and attitude towards treatment of patients with HIV and the perceived source of information related to HIV. The willingness to treat HIV-positive patients among dental students was 67.0%, and 74.20% were confident of treating a patient with HIV/AIDS. The potential problems in rendering treatment to these patients were effect on the attitude of other patients (49.90%) and staff fears (52.50%). The correct knowledge regarding the infection-control practice (barrier technique) was found among only 15.50% of respondents. The respondents had sufficient knowledge regarding the oral manifestations of HIV/AIDS. There was no correlation between the knowledge and attitude score, demonstrating a gap between knowledge and attitude among dental students regarding treatment of HIV-infected patients. Appropriate knowledge has to be delivered through the dental education curriculum, which can instil confidence in students about their ability to manage HIV-positive patients. © 2014 FDI World Dental Federation.

Unusual thromboses associated with protein S deficiency in patients with acquired immunodeficiency syndrome: case reports and review of the literature.

Recent reports indicate that patients infected with HIV are at increased risk for the development of thrombosis. Among other possibilities, an acquired deficiency of protein S (PS), one of the plasma's natural anticoagulants, might explain this tendency. PS deficiency can be classified in three types depending on the levels of total and free protein (antigenic assays) as well as anticoagulant activity (functional assay). Although the prevalence of inherited PS deficiency is not known because of its rarity, several conditions can lead to acquired forms of the disease. We report two AIDS patients with coexistent type III PS deficiency and thrombosis. Our first patient presented with bilateral chronic leg ulcers and a skin biopsy revealed dermal microthromboses. On laboratory evaluation he had PS deficiency and was started on anticoagulation, but was lost to follow-up. The second patient presented with hepatic vein thrombosis (Budd-Chiari syndrome) and was also PS deficient. On long-term anticoagulation, she experienced resolution of the thrombosis. Neither patient had prior personal or family history of venous thrombosis, nor acquired risk factors such as immobility, acute infection, recent surgery, or hormonal therapy. The literature contains a few reports of skin ulcers and Budd-Chiari syndrome associated with PS deficiency, although none in AIDS patients. While a larger number of studies describe an association between PS deficiency and HIV infection, the causal effect of this deficiency on the thrombophilic tendency in AIDS has not been established. We propose that awareness of the increased risk for thrombosis in HIV infection is important to the understanding of disease pathophysiology and management of these patients.

Risk of tuberculosis in immigrant Asians: culturally acquired immunodeficiency?

Study of the 620 Asian immigrants with tuberculosis notified in the Wandsworth area of south London between 1973 and 1988 showed a bimodal pattern of tuberculosis notifications: in 1977 there was a peak among Asians from East Africa, and in 1981 a peak among those from the Indian subcontinent. There was a mean lag time of five years between clinical presentation and immigration. Logit analysis showed that, although overall more men had tuberculosis than women, glandular tuberculosis was more common among women of all groups, and pulmonary tuberculosis was more common among Hindu women than Hindu men. Both subgroups of Asians had a substantially higher incidence of tuberculosis than white people, particularly at extrapulmonary sites. Hindus were also at a significantly greater risk of tuberculosis at all sites than Muslims (Hindu:Muslim risk ratio 5.5 for women and 3.7 for men). The increased susceptibility to tuberculosis of Hindus, particularly Hindu women, may be related to a culturally acquired immunodeficiency caused by vegetarianism and associated vitamin deficiency.

Studies show that nearly 40 million people are living with human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) around the world and since the beginning of the epidemic, about 35 million have died from AIDS. Heterosexual intercourse is the most common route for transmission of HIV infection (85%). People with a sexually transmitted infection (STI), such as syphilis, genital herpes, chancroid, or bacterial vaginosis, are more likely to obtain HIV infection during sex. On the other hand, a patient with HIV can acquire other infections such as hepatitis C virus (HCV) and hepatitis B virus (HBV) and also STIs. Co-infections and co-morbidities can affect the treatment route of patients with HIV/AIDs. Sometimes, physicians should treat these infections before treating the HIV infection. Therefore, it is important to identify co-infection or comorbidity in patients with HIV/AIDS. This study was conducted in order to understand the prevalence of HIV/AIDS/STI co-infection. In this cross-sectional study, we evaluated all HIV/AIDS patients who were admitted to the infectious wards of Boo-Ali hospital (Southeastern Iran) between March 2000 and January 2015. All HIV/AIDS patients were studied for sexually transmitted infections (STI) such as syphilis, gonorrhea, hepatitis B virus (HBV) and genital herpes. A questionnaire including data on age, sex, job, history of vaccination against HBV, hepatitis B surface antigen (HBsAg), hepatitis B core antibody (anti-HBc), hepatitis B surface antigen (anti-HBs), HCV-Ab, venereal disease research laboratory (VDRL) test, fluorescent treponemal antibody absorption (FTA-Abs) test, and urine culture was designed. Data was analyzed by the Chi square test and P values of < 0.05 were considered significant. Among the 41 patients with HIV/AIDS (11 females and 30 males; with age range of 18 to 69 years) five cases (12.1%) had a positive test (1:8 or more) for VDRL. The FTA-Abs was positive for all patients who

To evaluate relationships between retinal vessel caliber and tests of visual function among people with AIDS. Longitudinal, observational cohort study. We evaluated data for participants without ocular opportunistic infections at initial examination (baseline) in the Longitudinal Studies of the Ocular Complications of AIDS (1998-2008). Visual function was evaluated with best-corrected visual acuity, Goldmann perimetry, automated perimetry (Humphrey Field Analyzer), and contrast sensitivity (CS) testing. Semi-automated grading of fundus photographs (1 eye/participant) determined central retinal artery equivalent (CRAE), central retinal vein equivalent (CRVE), and arteriole-to-venule ratio (AVR) at baseline. Multiple linear regression models, using forward selection, sought independent relationships between indices and visual function variables. Included were 1250 participants. Smaller AVR was associated with reduced visual field by Goldmann perimetry (P = .003) and worse mean deviation (P = .02) on automated perimetry and possibly with worse pattern standard deviation (PSD) on automated perimetry (P = .06). There was a weak association between smaller AVR and worse CS (P = .07). Relationships were independent of antiretroviral therapy and level of immunodeficiency (CD4+ T lymphocyte count, human immunodeficiency virus [HIV] RNA blood level). On longitudinal analysis, retinal vascular indices at baseline did not predict changes in visual function. Variation in retinal vascular indices is associated with abnormal visual function in people with AIDS, manifested by visual field loss and possibly by reduced CS. Relationships are consistent with the hypothesis that HIV-related retinal vasculopathy is a contributing factor to vision dysfunction among HIV-infected individuals. Longitudinal studies are needed to determine whether changes in indices predict change in visual function. Copyright © 2012 Elsevier Inc. All rights reserved.

Immunotherapy of murine retrovirus-induced acquired immunodeficiency by CD4 T regulatory cell depletion and PD-1 blockade.

PubMed

Li, Wen; Green, William R

2011-12-01

LP-BM5 retrovirus induces a complex disease featuring an acquired immunodeficiency syndrome termed murine AIDS (MAIDS) in susceptible strains of mice, such as C57BL/6 (B6). CD4 T helper effector cells are required for MAIDS induction and progression of viral pathogenesis. CD8 T cells are not needed for viral pathogenesis, but rather, are essential for protection from disease in resistant strains, such as BALB/c. We have discovered an immunodominant cytolytic T lymphocyte (CTL) epitope encoded in a previously unrecognized LP-BM5 retroviral alternative (+1 nucleotide [nt]) gag translational open reading frame. CTLs specific for this cryptic gag epitope are the basis of protection from LP-BM5-induced immunodeficiency in BALB/c mice, and the inability of B6 mice to mount an anti-gag CTL response appears critical to the initiation and progression of LP-BM5-induced MAIDS. However, uninfected B6 mice primed by LP-BM5-induced tumors can generate CTL responses to an LP-BM5 retrovirus infection-associated epitope(s) that is especially prevalent on such MAIDS tumor cells, indicating the potential to mount a protective CD8 T-cell response. Here, we utilized this LP-BM5 retrovirus-induced disease system to test whether modulation of normal immune down-regulatory mechanisms can alter retroviral pathogenesis. Thus, following in vivo depletion of CD4 T regulatory (Treg) cells and/or selective interruption of PD-1 negative signaling in the CD8 T-cell compartment, retroviral pathogenesis was significantly decreased, with the combined treatment of CD4 Treg cell depletion and PD-1 blockade working in a synergistic fashion to substantially reduce the induction of MAIDS.

Since the discovery of human immunodeficiency virus (HIV) as the causative agent of acquired immunodeficiency syndrome in 1983, there has been a proliferation of diagnostic tests. These assays can be used to detect the presence of HIV antibody, HIV antigen, HIV ribonucleic and deoxyribonucleic acids, and HIV reverse transcriptase. Enzyme-linked immunosorbent assays, Western blot, radioimmunoprecipitation assays, indirect immunofluorescence assays, reverse transcriptase assays, and several molecular hybridization techniques are currently available. Enzyme-linked immunosorbent, Western blot, and indirect immunofluorescence assays for HIV antibody are very sensitive, specific, and adaptable to most laboratories. An enzyme-linked immunosorbent assay for HIV antigen is also readily adaptable to most laboratories and will be commercially available soon. While the other assays are more tedious, they are valuable confirmatory tests and are suitable for reference laboratories. The biohazards of performing HIV testing can be minimized with proper biosafety measures. Images PMID:3060241

Human immunodeficiency virus (HIV) and Treponema pallidum coinfection is relatively common and accounts for about 25% of primary and secondary syphilis. Tertiary syphilis in HIV-uninfected and HIV-infected patients is vanishingly rare. This is most likely due to early treatment of cases of primary and secondary syphilis. There is rapid progression to tertiary syphilis in HIV-infected patients. A 49-year-old woman diagnosed with HIV Type 1 infection and cluster of differentiation 4 (CD4) count of 482 presented with a four-week history of multiple crusted plaques, nodules, and ulcers on her face, arms, and abdomen. Her past history revealed red painful eyes six months prior to this presentation. She had generalized lymphadenopathy, no alopecia, and no palmar-plantar or mucosal lesions. There were no features suggestive of secondary syphilis. Neurological examination was normal. Her rapid plasma reagin test was positive to a titer of 64. She was treated with Penicillin G 20 mu IVI daily for 2 weeks. Penicillin remains the treatment of choice in syphilitic infected HIV negative and HIV-infected individuals. In neurosyphilis, the dose of Penicillin GIVI is 18-24 mu daily for 10-14 days. This case report demonstrates the importance of excluding syphilis in any HIV-infected patient.

Feline immunodeficiency virus (FIV) is a naturally occurring lentivirus of domestic and nondomestic feline species. Infection in domestic cats leads to immune dysfunction via mechanisms similar to those caused by human immunodeficiency virus (HIV) and, as such, is a valuable natural animal model for acquired immunodeficiency syndrome (AIDS) in humans. An association between FIV and an increased incidence of neoplasia has long been recognized, with frequencies of up to 20% in FIV-positive cats recorded in some studies. This is similar to the rate of neoplasia seen in HIV-positive individuals, and in both species neoplasia typically requires several years to arise. The most frequently reported type of neoplasia associated with FIV infection is lymphoma. Here we review the possible mechanisms involved in FIV lymphomagenesis, including the possible involvement of coinfections, notably those with gamma-herpesviruses. © The Author 2016.

Common Variable Immuno-Deficiency (CVID) is the most common symptomatic primary antibody-deficiency syndrome, but the basic immunologic defects underlying this syndrome are not well defined. We report here that among eight patients studied (six CVID and two hypogammaglobulinemic patients with recurrent infections), there is in two CVID patients a dramatic reduction in Ig V gene somatic hypermutation with 40-75% of IgG transcripts totally devoid of mutations in the circulating memory B cell compartment. Functional assays of the T cell compartment point to an intrinsic B cell defect in the process of antibody affinity maturation in these two cases.

Infectious complications of the primary immunodeficiencies.

The primary manifestation of the immunodeficiencies is undue susceptibility to infection. This means too many, too severe, too prolonged, too complicated and too unusual infections. Infections in immunodeficiency have a characteristic cause depending on the nature of the immune deficiency. Antibody deficiencies are associated with infections with gram-positive infections. Cellular immune deficiencies are associated with mycobacterial, protozoan, fungus, virus, and opportunistic bacterial infection. Phagocytic disorders are associated with staphylococcal, fungal, and gram-negative organisms. Complement disorders are associated by neisserial infections. Infections have also been implicated in the pathogenesis of some immunodeficiencies in some circumstances. These include human T lymphotropic virus type III (HTLV-III), rubella virus, cytomegalovirus, and Epstein-Barr virus. Several infectious syndromes in specific immunodeficiencies have been identified. Examples include enteric cytopathic human orphan (ECHO) virus encephalitis in agammaglobulinemia, and meningococcal meningitis in C6 deficiency. Infections can also be induced by live vaccines given in immunodeficiency (e.g., paralytic polio in agammaglobulinemia.) Unusual infectious syndromes will be illustrated including parainfluenza infection in severe combined and immunodeficiency, Legionella pneumonia in chronic granulomatous disease, and Cryptosporidium infection in hyper-IgM immunodeficiency.

The goal of this presentation is the description of the epidemiologic evolution and changes in natural history of the human immunodeficiency virus infection (HIV) epidemic itself and its relation with the acquired immunodeficiency syndrome-related lymphoma (ARL). We have started with the description of the world's state of the HIV epidemic, its features since the first case report in the United States of America in 1981, through the peak of new diagnoses in 1993 until the event that changed the natural history of the disease: the era of the widespread use of the highly active antiretroviral therapy (HAART), introduced in 1995 in the world and in 1997 in our country. The widespread introduction of HAART led to dramatic reductions in AIDS related mortality and morbidity throughout the developed world with a marked fall in the incidence of the major opportunistic infections in AIDS. We describe the main risk factors for the development of ARL, and the prognostic factors for survival and response to treatment. There is no clear definition in the literature of the roll that has played the use of HAART in relation to survival and response to treatment in ARL, but there is evidence that the basal count of CD4 cells has increased with HAART, leading to a better survival and response in ARL. The debate regarding this issue is surely affected by factors such as degree of antiretroviral treatment compliance, antiretroviral therapy resistance and chemotherapy heterogeneity. Finally we present the preliminary results of the analysis of our experience in ARL from 1986 to 2003.

To analyze the imaging features of (18)F-fluorodeoxyglucose (¹⁸F-FDG) positron emission tomography(PET)/computed tomography (CT) in acquired immune deficiency syndrome-related lymphoma (ARL) patients correlated with their clinical signs, symptoms, and treatments. Five ARL patients underwent ¹⁸F-FDG PET/CT at Peking Union Medical College Hospital from October 2008 to January 2013. Two patients received two additional follow-up studies 6 months later. Among these 5 patients, ¹⁸FDG-PET/CT helped in diagnosis of two patient and changed therapeutic strategy in other two patients. In two patients underwent ¹⁸F-FDG PET/CT brain scans, low-metabolism lesion was newly found in cerebral cortex. Of 4 patients receiving highly active antiretroviral therapy, PET/CT also demonstrated diffusely elevated ¹⁸F-FDG uptake in subcutaneous adipose tissue in two patients. ¹⁸F-FDG PET/CT is a highly useful tool in the diagnosis and treatment of ARL patients, in particular in the identification of associated encephalopathy and lipodystrophy.

Background. Predictors of thyroid dysfunction in HIV are not well determined. This study aimed to determine the prevalence and predictors of thyroid dysfunction in HIV infected Indians. Methods. Consecutive HIV patients, 18-70 years of age, without any severe comorbid state, having at least 1-year follow-up at the antiretroviral therapy clinic, underwent clinical assessment and hormone assays. Results. From initially screened 527 patients, 359 patients (61.44 ± 39.42 months' disease duration), having good immune function [CD4 count >200 cell/mm(3): 90.25%; highly active antiretroviral therapy (HAART): 88.58%], were analyzed. Subclinical hypothyroidism (ScH) was the commonest thyroid dysfunction (14.76%) followed by sick euthyroid syndrome (SES) (5.29%) and isolated low TSH (3.1%). Anti-TPO antibody (TPOAb) was positive in 3.90%. Baseline CD4 count had inverse correlation with TPOAb after adjusting for age and body mass index. Stepwise linear regression revealed baseline CD4 count, TPOAb, and tuberculosis to be best predictors of ScH after adjusting for age, weight, duration of HIV, and history of opportunistic fungal and viral infections. Conclusion. Burden of thyroid dysfunction in chronic HIV infection with stable immune function is lower compared to pre-HAART era. Thyroid dysfunction is primarily of nonautoimmune origin, predominantly ScH. Severe immunodeficiency at disease onset, TPOAb positivity, and tuberculosis were best predictors of ScH.

Autoimmunity and primary immunodeficiency: two sides of the same coin?

PubMed

Schmidt, Reinhold E; Grimbacher, Bodo; Witte, Torsten

2017-12-19

Autoimmunity and immunodeficiency were previously considered to be mutually exclusive conditions; however, increased understanding of the complex immune regulatory and signalling mechanisms involved, coupled with the application of genetic analysis, is revealing the complex relationships between primary immunodeficiency syndromes and autoimmune diseases. Single-gene defects can cause rare diseases that predominantly present with autoimmune symptoms. Such genetic defects also predispose individuals to recurrent infections (a hallmark of immunodeficiency) and can cause primary immunodeficiencies, which can also lead to immune dysregulation and autoimmunity. Moreover, risk factors for polygenic rheumatic diseases often exist in the same genes as the mutations that give rise to primary immunodeficiency syndromes. In this Review, various primary immunodeficiency syndromes are presented, along with their pathogenetic mechanisms and relationship to autoimmune diseases, in an effort to increase awareness of immunodeficiencies that occur concurrently with autoimmune diseases and to highlight the need to initiate appropriate genetic tests. The growing knowledge of various genetically determined pathologic mechanisms in patients with immunodeficiencies who have autoimmune symptoms opens up new avenues for personalized molecular therapies that could potentially treat immunodeficiency and autoimmunity at the same time, and that could be further explored in the context of autoimmune rheumatic diseases.

Influence of the home environment on the prevention of mother to child transmission of human immunodeficiency virus/acquired immune-deficiency syndrome in South Africa.

The human immunodeficiency virus and acquired immune-deficiency syndrome (HIV/AIDS) is still a 'family crises' which marks the beginning of the deterioration of the family unit and the trauma in the emotional, psychological and material lives of both the mother and child. In South African context where the majority of HIV-positive mothers are young single women who live in extended families, disclosure to the sexual partner alone is not an adequate condition for the success of prevention of mother to child transmission (PMTCT). In South Africa, close to one in three women who attend antenatal clinics are HIV positive. KwaZulu-Natal is one of the worst affected provinces, where as many as 40-60% of pregnant women attending antenatal services are living with HIV infection. The study sought to investigate the link between the home environment and its contribution to the success of the programme on PMTCT of HIV/AIDS. A qualitative, explorative, descriptive and contextual study was used in this study to explore whether the home environment for the support system is available for the HIV-positive women on the PMTCT programme. The population of this study included all women who have undergone counselling and tested HIV positive and who have joined the programme on PMTCT of HIV/AIDS in a specific hospital in KwaZulu-Natal Province. Although 14 women agreed to participate in the study, only 10 women were interviewed as saturation was attained. Data were collected using semi-structured interview schedule. Interviews were audio-taped and field notes were taken. Content analysis was used and it was done manually. This study revealed that one of the major issues still surrounding HIV/AIDS and PMTCT is that of non-disclosure, selective disclosure and the stigma and discrimination that surrounds this disease.

Natural hosts for simian immunodeficiency virus (SIV)can be, and are often naturally, infected with species-specific SIVs, but do not develop acquired immunodeficiency syndrome (AIDS). These natural hosts maintain high SIV viral loads, but avoid immunodeficiency. Elucidating the mechanisms that allow natural hosts to co-exist with SIV without overt disease may provide crucial information for understanding AIDS pathogenesis. Over the past few years, several key features of natural SIV infections have been described in studies conducted predominantly in sooty mangabeys (SMs), African green monkeys (AGMs), and mandrills. Natural SIV hosts are able to avoid the chronic, generalized immune system activation that is associated with disease progression in HIV-infected individuals and are known to down-modulate the expression of the receptors for SIV. In this perspective we propose that a critical factor that differentiates nonprogressive from progressive HIV or SIV infection is the maintenance of T cell immune competence in the face of a virus that infects and kills CD4+ T cells Elucidation of the mechanisms underlying the preservation of immune function during and after the acute phase of natural SIV infection may lead to the design of novel preventive and therapeutic interventions for treatment of chronic HIV infection.

Community-Acquired Pneumonia in Latin America.

Community-acquired pneumonia (CAP) is associated with significant morbidity and mortality in Latin America and the Caribbean (LAC) region. Poverty, socioeconomic factors, and malnutrition influence the incidence and outcome of CAP in LAC. In LAC, Streptococcus pneumoniae is the most frequent microorganism responsible for CAP, (incidence: 24-78%); the incidence of atypical microorganisms is similar to other regions of the world. Human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) is a growing problem in the LAC region, with the Caribbean being the second most affected area worldwide after Sub-Saharan Africa. Pneumococcal pneumonia remains the most common cause of CAP in HIV-infected patients, but Pneumocystis jirovecii and tuberculosis (TB) are also common in this population. The heterogeneity of the health care systems and social inequity between different countries in LAC, and even between different settings inside the same country, is a difficult issue. TB, including multidrug-resistant TB, is several times more common in South American and Central American countries compared with North America. Furthermore, hantaviruses circulating in the Americas (new world hantaviruses) generate a severe respiratory disease called hantavirus pulmonary syndrome, with an associated mortality as high as 50%. More than 30 hantaviruses have been reported in the Western Hemisphere, with more frequent cases registered in the southern cone (Argentina, Chile, Uruguay, Paraguay, Bolivia, and Brazil). Respiratory viruses (particularly influenza) remain an important cause of morbidity and mortality, particularly in the elderly. Low rates of vaccination (against influenza as well as pneumococcus) may heighten the risk of these infections in low- and middle-income countries.

According to the 15 autopsies performed at the Department of Pathological Anatomy, Escola Paulista de Medicina, São Paulo, Brazil, it was confirmed that acquired immunodeficiency syndrome (AIDS) occurs preferably in young homosexual males, who die in a short period of time of the disease, which leads to a consumptive state verified by cachexia of the cadavers. The most affected organs of this series were the lungs and encephalum, exactly the ones responsible for the immediate cause of death. In this series of autopsies there were 9 types of microorganisms represented by virus, bacteria, fungi, protozoans and two types of tumors, Kaposi's sarcoma and lymphoma of the central nervous system. From the microorganisms, the most frequent was the Cytomegalovirus and, from the tumors, Kaposi's sarcoma. The various types of microorganisms were frequently associated, principally in the central nervous and digestive systems. There was also association of microorganisms with tumors. Besides the lesions produced by microorganisms there were other associated alterations as brown atrophy of neuronia, which was related to the infiltration of cerebral lymphoma, and the lymphocytic depletion of lymphoid organs due to immunological exhaustion. Cellular reaction to microorganisms was practically none, principally with Pneumocystis carinii and Cryptococcus neoformans, the first one behaving as an inert mould in the pulmonary alveoli and the second proliferating freely in tissues. In two cases there was no granulomatous reaction to Mycobacterium tuberculosis. The primary lymphoma of the central nervous system should be interpreted as a microglioma, i.e., a reticulosarcoma of this system according to Hortega's school.

One out of three pediatric sepsis deaths in high income countries occur in previously healthy children. Primary immunodeficiencies (PIDs) have been postulated to underlie fulminant sepsis, but this concept remains to be confirmed in clinical practice. Pseudomonas aeruginosa ( P. aeruginosa ) is a common bacterium mostly associated with health care-related infections in immunocompromised individuals. However, in rare cases, it can cause sepsis in previously healthy children. We used exome sequencing and bioinformatic analysis to systematically search for genetic factors underpinning severe P. aeruginosa infection in the pediatric population. We collected blood samples from 11 previously healthy children, with no family history of immunodeficiency, who presented with severe sepsis due to community-acquired P. aeruginosa bacteremia. Genomic DNA was extracted from blood or tissue samples obtained intravitam or postmortem. We obtained high-coverage exome sequencing data and searched for rare loss-of-function variants. After rigorous filtrations, 12 potentially causal variants were identified. Two out of eight (25%) fatal cases were found to carry novel pathogenic variants in PID genes, including BTK and DNMT3B . This study demonstrates that exome sequencing allows to identify rare, deleterious human genetic variants responsible for fulminant sepsis in apparently healthy children. Diagnosing PIDs in such patients is of high relevance to survivors and affected families. We propose that unusually severe and fatal sepsis cases in previously healthy children should be considered for exome/genome sequencing to search for underlying PIDs.

Acquired bone marrow failure syndromes encompass a unique set of disorders characterized by a reduction in the effective production of mature cells by the bone marrow (BM). In the majority of cases, these syndromes are the result of the immune-mediated destruction of hematopoietic stem cells or their progenitors at various stages of differentiation. Microbial infection has also been associated with hematopoietic stem cell injury and may lead to associated transient or persistent BM failure, and recent evidence has highlighted the potential impact of commensal microbes and their metabolites on hematopoiesis. We summarize the interactions between microorganisms and the host immune system and emphasize how they may impact the development of acquired BM failure.

Hyponatremia is often observed in patients with Legionella pneumonia. However, other electrolyte abnormalities are uncommon and the mechanism remains to be clarified. We experienced two male cases of acquired Fanconi syndrome associated with Legionella pneumonia. The laboratory findings at admission showed hypophosphatemia, hypokalemia, hypouricemia and/or hyponatremia. In addition, they had the generalized dysfunction of the renal proximal tubules presenting decreased tubular reabsorption of phosphate (%TRP), increased fractional excretion of potassium (FEK) and uric acid (FEUA), low-molecular-weight proteinuria, panaminoaciduria and glycosuria. Therefore, they were diagnosed as Fanconi syndrome. Treatment for Legionella pneumonia with antibiotics resulted in the improvement of all serum electrolyte abnormalities and normalization of the %TRP, FEK, FEUA, low-molecular-weight proteinuria, panaminoaciduria and glycosuria, suggesting that Legionella pneumophila infection contributed to the pathophysiology of Fanconi syndrome. To the best of our knowledge, this is the first report demonstrating Fanconi syndrome associated with Legionella pneumonia.

The presentation of Pneumocystis pneumonia (PCP) in previously healthy men having sex with men (MSM) in San Francisco and New York City in 1981 heralded the beginning of the human immunodeficiency virus (HIV) pandemic. Despite a decreasing incidence of PCP among patients with HIV/AIDS (acquired immunodeficiency syndrome) since the advent of combination antiretroviral therapy in the mid-1990s, PCP remains one of the most common AIDS-defining opportunistic infections in the United States and Western Europe. Newer molecular diagnostic tests in conjunction with standard immunofluorescent or colorimetric tests have allowed for more rapid and accurate diagnosis. Although several effective oral and intravenous therapies exist to treat PCP, mortality rates in HIV-infected individuals remain unacceptably high, especially in those with advanced AIDS. The identification of specific mutations in Pneumocystis genes targeted by trimethoprim-sulfamethoxazole has raised concerns about the development of resistance to the drug of choice and may ultimately lead to greater utilization of alternative therapies to treat PCP in the future.

The screening of anti-Human Immunodeficiency Virus antibodies is mandatory in every blood donor admitted to the Blood Bank of Kinshasa University Clinics since 1984. However, no compiled data are available to date. The objective of this study was to establish the trend, prevalence, viral co-infections, and determinants of Human Immunodeficiency anti-Virus serology in blood donors admitted between 2003-2006 and 2008-2013. A retrospective analysis was carried out at University Kinshasa Clinics, using blood donors' records during 2003-2006 and 2008-2013. The prevalence of the human immunodeficiency virus per year, age, sex and type of blood donors were estimated. Independent predictors of human immunodeficiency virus seropositivity were also identified. Out of 26,341 blood donors, 2.2% (n=576/26,341) were seropositive for Human Immunodeficiency Virus. Age<25 years (OR=1.7; 95% CI: 1.4-2; P<0.0001) and Hepatitis C virus seropositivity (OR=3; 95% CI; 1.8-4.9; P<0.001) emerged as independent predictors of Human Immunodeficiency Virus seropositivity. This study shows a strong association between the Human Immunodeficiency Virus and hepatitis C and younger age respectively. Further studies are needed to ensure safety of Blood donation in Democratic Republic of Congo. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

To determine the prevalence of loss to follow-up (PLF) and risk factors among human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) patients from 1989 to 2012 in Baoshan city, Yunnan province. The epidemic and follow-up databases of HIV/AIDS patients by the end of 2012 were downloaded from "the history card downloading site" of HIV/AIDS database in China Information System for Disease Control and Prevention and obtained the related data of patients from 1989 to 2012 who had local residence in Baoshan city. These data included demographic characteristics (genders, age at the time of HIV testing positive, and occupation, marital status, and education levels, et al), transmission routes, and disease staging, antiretroviral therapy (ART), and sources of samples, the first CD4(+)T cell counts, and status of follow-up, et al. Descriptive epidemiological study was used to describe the general characteristics of loss to follow-up. Multivariable Cox regression was used for determining risk factors associated with loss to follow-up. A total of 3 295 eligible HIV/AIDS patients from 1989 to 2012 were included. The accumulative study person-year was 11 416.59 years, 222 HIV/AIDS patients were lost to follow-up, and the PLF was 0.019 4/ person years (py).

In the large Zika virus (ZIKV) epidemic that occurred in Brazil in 2015, the intrauterine fetal exposure to ZIKV was associated with a significant risk of developing microcephaly and neurological disorders in the infected infants. ZIKV-associated disease has since been reported in 24 countries in the Americas. At present, definitive evidence is lacking regarding the intrauterine co-exposure to ZIKV and other viral infections and whether the coinfection impacts the risk of acquiring either infection or disease severity. Here, we provide evidence of intrauterine exposure to both ZIKV and human immunodeficiency virus (HIV) infections, causing congenital Zika syndrome in an HIV-exposed uninfected infant. Clinical, imaging and laboratory examinations of the pregnant woman and the newborn were performed. Histopathology, ZIKV/HIV-specific immunoassays, and ultrastructural evaluation of the placenta were performed. The Zika-asymptomatic, HIV-positive pregnant woman underwent ultrasounds revealing fetal cerebral ventriculomegaly, microcephaly, and brain atrophy. Her baby girl was born small for gestational age and with the neurological sequelae of congenital Zika syndrome. The evaluation of the abnormally large term placenta revealed severe damage to the maternal decidua and chorionic villi, cells positive for ZIKV-specific antigens but not for HIV antigens, and intracellular membranous clusters of virus-like particles approximately 25 nm in diameter. The rapid progression and severity of the congenital Zika syndrome may be related to the uncontrolled HIV disease in the mother. The poor inflammatory response observed in the placenta may have reduced the inherent risk of mother-to-child transmission of HIV.

In Japan, hepatitis B virus (HBV) and hepatitis C virus (HCV) infections have decreased; however, human immunodeficiency virus (HIV) infection has increased. Antiviral treatment against these viruses has been established. With antiviral medicines, HBV DNA and HIV RNA levels decrease to under the detectable limits and HCV is completely eliminated from almost 90% of infected patients. Furthermore, the morbidities associated with hepatocellular carcinoma and acquired immunodeficiency syndrome (AIDS) have decreased. The: appearance of antiviral-resistant HBV and HCV is a concern because long-term treatment is needed against these viruses. Patients infected with HBV in the past have the potential to develop de novo hepatitis with immunosuppressive treatment, in spite of being HBsAg-negative and with HBV DNA under the detectable level.

Progressive multifocal leukoencephalopathy (PML) is a demyelinating disease of the central nervous system (CNS) caused by JC virus infection in oligodendrocytes, especially in patients with acquired immunodeficiency syndrome (AIDS). Movement disorders associated with PML are very rare. Here, we report a case of PML in an AIDS patient who presented with a cerebellar tremor, caused by lesions in the cerebellar outflow tract. A cerebellar tremor can be a rare clinical manifestation in patients with PML. PMID:24868366

The presence of human immunodeficiency virus (HIV) antigens in cerebrospinal fluid (CSF) was associated with progressive encephalopathy in adult and pediatric patients with acquired immunodeficiency syndrome (AIDS). HIV antigen was detected in CSF from 6 of 7 AIDS patients with progressive encephalopathy. By contrast, HIV antigen, whether free or complexed, was detected in CSF from only 1 of 18 HIV antibody seropositive patients without progressive encephalopathy and from 0 of 8 experimentally infected chimpanzees without clinical signs. Intra-blood-brain barrier synthesis of HIV-specific antibody was demonstrated in the majority of patients with AIDS (9/12) or at risk for AIDS (8/13) as well as in the experimentally infected chimpanzees, indicating HIV-specific B-cell reactivity in the brain without apparent neurological signs. In 6 of 11 patients with HIV infection, antibodies synthesized in the central nervous system were directed against HIV envelope proteins. Active viral expression appears to be necessary for both the immunodeficiency and progressive encephalopathy associated with HIV infection.

Antiretroviral therapy for human immunodeficiency virus infection in 1997.

It has become clear that the acquired immunodeficiency syndrome follows continuous replication of the human immunodeficiency virus (HIV) and a decrease in immune capability, most obviously a decline in the number of CD4 lymphocytes. An understanding of key elements in the infectious life cycle of HIV has led to the development of potent antiretroviral drugs selectively targeting unique reverse transcriptase and protease enzymes of the virus. Completed clinical trials have shown that antiretroviral therapy for HIV infection, begun early, reduces viral replication and reverses the decline in CD4 lymphocyte numbers. Recent studies of combination therapies have shown that decreases in plasma HIV viremia to low levels and sustained increases in CD4 cell numbers are associated with longer survival. Potent combination regimens including protease inhibitors and non-nucleoside reverse transcriptase inhibitors suppress detectable viral replication and have demonstrated clinical benefits in patients with advanced disease. Progress in antiretroviral therapy and methods to monitor responses to treatment are providing new hope in the treatment of HIV infection. PMID:9217434

Pharmacological inhibition of feline immunodeficiency virus (FIV).

Feline immunodeficiency virus (FIV) is a member of the retroviridae family of viruses and causes an acquired immunodeficiency syndrome (AIDS) in domestic and non-domestic cats worldwide. Genome organization of FIV and clinical characteristics of the disease caused by the virus are similar to those of human immunodeficiency virus (HIV). Both viruses infect T lymphocytes, monocytes and macrophages, and their replication cycle in infected cells is analogous. Due to marked similarity in genomic organization, virus structure, virus replication and disease pathogenesis of FIV and HIV, infection of cats with FIV is a useful tool to study and develop novel drugs and vaccines for HIV. Anti-retroviral drugs studied extensively in HIV infection have targeted different steps of the virus replication cycle: (1) inhibition of virus entry into susceptible cells at the level of attachment to host cell surface receptors and co-receptors; (2) inhibition of fusion of the virus membrane with the cell membrane; (3) blockade of reverse transcription of viral genomic RNA; (4) interruption of nuclear translocation and viral DNA integration into host genomes; (5) prevention of viral transcript processing and nuclear export; and (6) inhibition of virion assembly and maturation. Despite much success of anti-retroviral therapy slowing disease progression in people, similar therapy has not been thoroughly investigated in cats. In this article we review current pharmacological approaches and novel targets for anti-lentiviral therapy, and critically assess potentially suitable applications against FIV infection in cats.

Lack of recognition of human immunodeficiency virus (HIV) infection especially in children and delayed implementation of effective control programs makes HIV infection as a major cause for concern. Information on HIV epidemiology in Iran as well as other Islamic countries is limited. The aim of our study was to describe the clinical manifestation and laboratory finding of HIV infected children who were admitted to a referral Children Medical Center (CMC) in Tehran, Iran, during 11 years from January 2002 to January 2013. This was a retrospective study carried out over a period of 11 years. The records of all patients attending to the CMC with confirmed acquired immunodeficiency syndrome (AIDS) were screened. The patients were evaluated for social circumstance, family history, age, gender, clinical, and laboratory features. Clinical data including fever, respiratory distress, diarrhea, rash, etc. as well as laboratory tests including complete blood count, serum glucose level, electrolytes, liver function test, cultures, CD4 lymphocyte count were evaluated. During the study period, 32 HIV positive children were enrolled. The majority of patients were presented with weight loss, prolonged fever, respiratory infection and chronic diarrhea. In this study, salmonella infections as well as streptococcal pneumonia and candida infections followed by, tuberculosis and Pseudomonas aeruginosa infections were the predominant opportunistic infections. Since the number of HIV-positive children has been alarmingly increasing in recent years and perinatal transmission is the most common route of HIV infection in children, essential recommendations for prenatal HIV testing as well as appropriate antiretroviral therapy by HIV infected mothers are needed. © 2015 Wiley Periodicals, Inc.

Survival in patients with acquired immunodeficiency syndrome (AIDS) related non-Hodgkin's Lymphoma has improved with the use of High Active Antiretroviral Therapy (HAART) and less toxic chemotherapy. Clinical characteristics and outcome among patients treated for AIDS related non-Hodgkin's Lymphoma are described. Nine patients were studied retrospectively. Overall survival (OS) and Free Disease Survival (FDS) using a Kaplan-Meier model were analyzed. Patients received (DA-EPOCH) etoposide, prednisone, vincristine, doxorubicin and cyclophosphamide. The overall Survival was 18 months and 13 month Free Disease Survival with a median follow-up of 16 months showing full response in 8/9 patients was observed. A very satisfactory treatment response in this group of patients expressed as an increased Overall Survival was noted.

Activated phosphatidylinositol-3-OH kinase-delta (PI3Kδ) syndrome type 1 (APDS1) is a recently described primary immunodeficiency syndrome characterized by recurrent respiratory infections, lymphoid hyperplasia, and herpesviridae infections due to germline gain-of-function mutations of PIK3CD. Hematopoietic stem cell transplantation (HSCT) may be considered to ameliorate progressive immunodeficiency and associated malignancy, but appropriate indications, method, and outcomes of HSCT for APDS1 remain undefined. Our objective was to analyze the clinical manifestations, laboratory findings, prognosis, and treatment of APDS1 and explore appropriate indications and methods of HSCT. We retrospectively reviewed the medical records of cohorts undergoing HSCT at collaborating facilities. Thirty-year overall survival was 86.1%, but event-free survival was 39.6%. Life-threatening events, such as severe infections or lymphoproliferation, were frequent in childhood and adolescence, and were common indications for HSCT. Nine patients underwent HSCT with fludarabine-based reduced intensity conditioning (RIC). Seven patients survived after frequent adverse complications and engraftment failure. Most symptoms improved after HSCT. Patients with APDS1 showed variable clinical manifestations. Life-threatening progressive combined immunodeficiency and massive lymphoproliferation were common indications for HSCT. Fludarabine-based RIC-HSCT ameliorated clinical symptoms, but transplant-related complications were frequent, including graft failure. Copyright © 2018. Published by Elsevier Inc.

This study represents the first epidemiological study based on the national registry of primary immunodeficiencies (PID) in Korea. Patient data were collected from 23 major hospitals. A total of 152 patients with PID (under 19 yr of age), who were observed from 2001 to 2005, have been entered in this registry. The period prevalence of PID in Korea in 2005 is 11.25 per million children. The following frequencies were found: antibody deficiencies, 53.3% (n = 81), phagocytic disorders, 28.9% (n = 44); combined immunodeficiencies, 13.2% (n = 20); and T cell deficiencies, 4.6% (n = 7). Congenital agammaglobulinemia (n = 21) and selective IgA deficiency (n = 21) were the most frequently reported antibody deficiency. Other reported deficiencies were common variable immunodeficiencies (n = 16), X-linked agammaglobulinemia (n = 15), IgG subclass deficiency (n = 4). Phagocytic disorder was mostly chronic granulomatous disease. A small number of patients with Wiskott-Aldrich syndrome, hyper-IgE syndrome, and severe combined immunodeficiency were also registered. Overall, the most common first manifestation was pneumonia. This study provides data that permit a more accurate estimation PID patients in Korea. PMID:22787376

Very early onset inflammatory bowel disease, diagnosed in children ≤5 years old, can be the initial presentation of some primary immunodeficiencies. In this study, we describe a 17-month-old boy with recurrent infections, growth failure, facial anomalies, and inflammatory bowel disease. Immune evaluation, whole-exome sequencing, karyotyping, and methylation array were performed to evaluate the child's constellation of symptoms and examination findings. Whole-exome sequencing revealed that the child was homozygous for a novel variant in ZBTB24, the gene associated with immunodeficiency, centromere instability, and facial anomalies type-2 syndrome. This describes the first case of inflammatory bowel disease associated with immunodeficiency, centromere instability, and facial anomalies type-2 syndrome in a child with a novel disease-causing mutation in ZBTB24 found on whole-exome sequencing.

Psychological problems of families and health workers dealing with people infected with human immunodeficiency virus 1.

The psychological problems of the families of human immunodeficiency virus 1 (HIV-1)-infected people, and of the health workers taking care of them, have been addressed in a few empirical studies and in several anecdotal reports and theoretical contributions. Apparently, HIV-1 infection and acquired immunodeficiency syndrome (AIDS) are able to elicit a wide range of emotional reactions, from rejection and refusal to provide care to immersion in the infected person's needs and burnout. Since irrational fears and attitudes play an important role in conditioning these reactions, education may not be sufficient to change behaviour. Counselling sessions and mutual support groups are often the most appropriate contexts where fears and concerns can receive an individually tailored response, and where formal and informal caregivers can be helped to manage stress.

To evaluate the rates of new-onset cytomegalovirus (CMV) retinitis and worsening existing CMV retinitis in patients with AIDS after initiating combination antiretroviral therapy (cART) and the role of an immune recovery inflammatory syndrome (IRIS). Cohort study. Immune recovery was defined as an increase in CD4 + T cells to ≥100 cells/μL; rates of new-onset CMV retinitis and of worsening of CMV retinitis (either increasing border activity or retinitis progression) were compared between those with and without immune recovery. Among patients without CMV retinitis, 1 of 75 patients with immune recovery developed CMV retinitis in the first 6 months after initiating cART vs 1 of 31 without immune recovery (P = .14). Among patients with CMV retinitis, the rates of retinitis progression and increasing retinitis border activity among patients during the first 6 months after initiating cART in those with immune recovery were 0.11 per person-year (PY; 95% confidence interval [CI] 0-0.62) and 0.11 per PY (95% CI 0-0.62), respectively, vs 0.67 per PY (95% CI 0.22-1.56) and 0.40 per PY (95% CI 0.08-1.17), respectively, for those without immune recovery (P = .11 and .47). Among persons with AIDS who experience immune recovery, there was neither an increased rate of new-onset CMV retinitis nor worsening of existing CMV retinitis in the first 6 months after initiating cART vs those without immune recovery. These data are consistent with the known 3- to 6-month lag in recovery of specific immunity to CMV after initiating cART and suggest that "immune recovery retinitis," a proposed immune recovery inflammatory syndrome phenomenon, is rare.

Primary Immunodeficiencies (PID) represent a group of heterogeneous immune diseases with important biological significance. We reviewed the records of children diagnosed with PID in the Referral Center for PID in our country in order to describe the epidemiological, clinical and laboratory characteristics of immunodeficient patients. During a 30-year period, 147 patients (101 males, 68.7 %), with a mean age of 6.5 years at the time of diagnosis, were diagnosed with PID. The most prevalent diagnoses of PID were: "Combined Immunodeficiency" in 46 (31.3 %) patients, "Well-defined immunodeficiency syndrome" in 35 (23.1 %) patients, "Predominantly antibody deficiency" in 30 (20.4 %) patients and "Congenital defect of phagocyte function or both" in 28 (19 %) patients. There was a higher prevalence of males with "Combined immunodeficiency" (p < 0.033) and "Predominantly antibody deficiency" (p < 0.02) compared to females. The median age of children at the onset of symptoms and at the time of diagnosis was 0.5y (IQR: 0.1-2.5) and 2y (IQR: 0.6-7.2), respectively. The median diagnostic delay was 0.9y (IQR: 0.2-4.8). This period was shorter for patients with "Combined immunodeficiency" [median 0.3y (IQR: 0.1-1)], and longer for those with "Predominantly antibody deficiency" [median 3.2y (IQR: 0.2-5.9) or "Disease of immune dysregulation" [median 3.2y (IQR: 0.1-6.6)]. Comparing the rates in our population with those of the European Registry (ESID), the rates of "Combined immunodeficiencies", "Well-defined syndromes" and "Congenital birth defects and/or function of phagocytes" were significantly higher in this study (p <0,001). PID registry analysis improves knowledge in the field of Immunology and enhances awareness, early detection, diagnosis, and management of this rare but significant group of diseases.

Histoplasma capsulatum var. capsulatum infection is rare outside disease-endemic areas. Clinical presentation and outcome of acquired immunodeficiency syndrome–related histoplasmosis are unknown in non-endemic areas with wide access to highly active anti-retroviral therapy (HAART). Retrospective analysis of cases recorded at the French National Reference Center for Mycoses and Antifungals during two decades: pre-HAART (1985–1994) and HAART (1997–2006). Clinical features and outcome of all adults with proven acquired immunodeficiency syndrome–related histoplasmosis were compared between the two periods. One hundred four patients were included (40 during the pre-HAART era and 64 during the HAART era). Diagnosis was established a mean of 62 days after onset of symptoms. One-year overall mortality rates decreased from 53% (pre-HAART era) to 22% (HAART era). Diagnosis during the pre-HAART era and an older age were the only independent factors associated with death. Histoplasmosis is a rare invasive fungal infection outside disease-endemic areas. Its prognosis improved significantly during the HAART era. PMID:22049053

Substantial progress has been made in China in using traditional Chinese medicine (TCM) to treat acquired immune deficiency syndrome (AIDS). Our objective was to review the latest developments in TCM treatment of AIDS in China between 2004 and 2014. We reviewed the content of original articles investigating the efficacy and safety of TCM for treating AIDS published in Chinese and English language journals. Relevant references from 2004 to 2014 were found using PubMed and the China National Knowledge Infrastructure Database. We found that TCM has been widely used for treating AIDS and its complications in China. The number of TCM studies has increased, which indicates efficacy and safety. Measures of efficacy in the reviewed articles included the alleviation of human immunodeficiency virus (HIV)-related signs and symptoms, improvements in quality of life, improvements in long-term survival, counteraction of the adverse side effects of antiviral drugs, promotion of immune reconstitution, and improvement of laboratory results. In sum, the literature indicates that TCM is safe. TCM plays an important role in the treatment of AIDS. Some studies have attempted to measure the efficacy and safety of TCM for treating AIDS, but more evidence is needed. Therefore, more research on this topic is required in the future.

Since the original description of X-linked agammaglobulinemia in 1952, the number of independent primary immunodeficiency diseases (PIDs) has expanded to more than 100 entities. By definition, a PID is a genetically determined disorder resulting in enhanced susceptibility to infectious disease. Despite the heritable nature of these diseases, some PIDs are clinically manifested only after prerequisite environmental exposures but they often have associated malignant, allergic, or autoimmune manifestations. PIDs must be distinguished from secondary or acquired immunodeficiencies, which are far more common. In this review, we will place these immunodeficiencies in the context of both clinical and laboratory presentations as well as highlight the known genetic basis. PMID:17162365

Refractory and relapsing crytocococcosis in acquired immune deficiency syndrome (AIDS) patients have a poor prognosis. The risk factors for this complicated infection course were evaluated by comparing refractory and/or relapsing cryptococcosis in human immunodeficiency virus-coinfected patients (cohort 1) with another group of AIDS patients who adequately responded to antifungals (cohort 2). Except for one isolate of Cryptococcus gattii from a cohort 2 case, all other isolates were identified as Cryptococcus neoformans var. grubii, sex type α, genotype VNI, including Cryptococcus reisolated from the relapse or in the refractory state. No differences were observed with respect to Cryptococcus capsule size and in the melanin and phospholipase production. The cohort 1 patients presented higher prevalence of cryptococcemia, cerebral dissemination, chronic liver disease, and leucopenia, and have increased death rate. Apparently, the refractory and/or relapsing cryptococcosis in the AIDS patients were more related to the host and the extent of the infection than to the fungal characteristics. © The American Society of Tropical Medicine and Hygiene.

Henan Province in China has a major epidemic of human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS). Chinese medicine (CM) has been used throughout the last decade, and a management modality was developed, which can be described by unified-planning, graded-administration, and centralized-controlling (UGC). The UGC modality has one primary concept (patient-centered medicine from CM theory), four basic foundations (classifying administrative region, characteristics of CM on disease treatment, health resource conditions, and distribution of patients living with HIV), six important relationships (the "three uniformities and three combinations," and the six relationships therein guide the treatment of AIDS with CM), and four key sections (management, operation, records, and evaluation). In this article, the authors introduce the UGC modality, which could be beneficial to developing countries or resource-limited areas for the management of chronic infectious disease.

Ralstonia pickettii-Induced Ataxia in Immunodeficient Mice

We report here the characterization of an asymmetric ataxia syndrome (head tilt and circling, with death in the most severe cases) demonstrated by profoundly immunodeficient mice housed at the Institut Curie SPF facility. The immune system of the affected mice had been genetically modified so that they were deficient in both B and T cells. Extensive bacteriologic, parasitic, serologic, and histopathologic analysis of the affected animals and their healthy controls led us to identify Ralstonia pickettii as the causative agent of the ataxic syndrome. The outbreak was managed through a test-and-cull process. Even though they also carried Ralstonia pickettii, immunocompetent mice that were kept in the same facility, did not show any of the signs that were expressed by their immunodeficient counterparts. This case highlights the difficulty of maintaining immunocompetent and immunodeficient mice in the same microbiologic unit and the importance of enlarging the spectrum of health monitoring to opportunistic agents when investigating clinical cases in populations of immunocompromised rodents.

Human immunodeficiency virus 2 infection is endemic in West Africa but is also found in parts of Europe, North and South America, and India where it is thought to have been introduced secondary to migration and commercial trade ties. It is less common than Human immunodeficiency virus 1, with differences in pathogenicity, lower rates of transmission, longer asymptomatic period and slower progression to acquired immunodeficiency syndrome. Human immunodeficiency virus 2 is also associated with diagnostic challenges given the lack of commercially available diagnostic tests, and management challenges given intrinsic resistance to many anti-retroviral therapies. We describe a case of a 65 year old South Indian female, visiting her family in Australia, who presented with weight loss, pancytopaenia and generalised lymphadenopathy on a background of newly diagnosed congestive cardiac failure. Multiple investigations were performed to elucidate the cause of her presentation, with the eventual unexpected diagnosis of human immunodeficiency virus 2. She was commenced on anti-retroviral treatment and made a remarkable recovery. We describe the challenges associated with diagnosis of human immunodeficiency virus 2 due to lack of commercially available diagnostics, as well as the treatment and management challenges including the fact that human immunodeficiency virus 2 is intrinsically resistant to non-nucleoside reverse transcriptase inhibitors. Human immunodeficiency virus 2 infection should be considered in patients who present with symptoms and signs that do not point towards a clear diagnosis, such as unexplained pancytopaenia or lymphadenopathy, and who have risk factors such as being from an endemic area or having had blood transfusions, especially prior to the commencement of blood-borne virus screening of blood donors.

Transgene expression from the plant's plastid genome represents a promising strategy in molecular farming because of the plastid's potential to accumulate foreign proteins to high levels and the increased biosafety provided by the maternal mode of organelle inheritance. In this article, we explore the potential of transplastomic plants to produce human immunodeficiency virus (HIV) antigens as potential components of an acquired immunodeficiency syndrome (AIDS) vaccine. It is shown that the HIV antigens p24 (the major target of T-cell-mediated immune responses in HIV-positive individuals) and Nef can be expressed to high levels in plastids of tobacco, a non-food crop, and tomato, a food crop with an edible fruit. Optimized p24-Nef fusion gene cassettes trigger antigen protein accumulation to up to approximately 40% of the plant's total protein, demonstrating the great potential of transgenic plastids to produce AIDS vaccine components at low cost and high yield.

With improved survival, more AIDS patients, especially heavy smokers and alcohol abusers, may be confronted with laryngeal squamous cell carcinoma. Since curative treatment may require aggressive combined therapy, these patients, often suffering from immunosupression and poor general condition, present unique therapeutic challenges. The objective of the study was to describe treatment dilemmas. This case report presents a detailed description of an AIDS patient with carcinoma of the larynx. A patient with T3N0M0 laryngeal carcinoma and AIDS underwent tracheotomy and biopsy, followed by severe neck and pulmonary infection. After convalescence, radiotherapy was administered, with no evidence of a disease during a 3.5-year follow-up. During his remaining life, the patient developed severe psychoaffective disorder, his immune state deteriorated until he demised from sepsis. In conclusion, patients with HIV infection, especially having a history of tobacco or alcohol abuse, should be carefully examined for head and neck carcinoma that is likely to be more aggressive. Following surgery, AIDS patients may have worse wound healing and a greater tendency to contract infections. Radiotherapy and especially chemotherapy may cause life-threatening complications. Although early detection may increase survival, curative treatment should involve many disciplines and extra caution.

Epstein-Barr virus immediate-early gene product trans-activates gene expression from the human immunodeficiency virus long terminal repeat

Kenney, S.; Kamine, J.; Markovitz, D.

Acquired immunodeficiency syndrome patients are frequently coinfected with Epstein-Barr virus (EBV). In this report, the authors demonstrate that an EBV immediate-early gene product, BamHI MLF1, stimulates expression of the bacterial chloramphenicol acetyltransferase (CAT) gene linked to the human immunodeficiency virus (HIV) promoter. The HIV promoter sequences necessary for trans-activation by EBV do not include the tat-responsive sequences. In addition, in contrast to the other herpesvirus trans-activators previously studied, the EBV BamHI MLF1 gene product appears to function in part by a posttranscriptional mechanism, since it increases pHIV-CAT protein activity more than it increases HIV-CAT mRNA.

Human immunodeficiency virus type 1 (HIV-1) can be transmitted through blood transfusion. The first transfusion-acquired immunodeficiency syndrome (AIDS) patient in Taiwan was a 46-year-old woman who received two units of whole blood during a hysterectomy at a provincial hospital in 1985. In 1991, she experienced a herpes zoster infection. In March 1993, she had extensive herpetic gingivostomatitis and another herpes zoster attack, and was treated at the same hospital. Two months later, she had oral candidiasis and was treated at a medical center. She was not tested for HIV-1 infection until she developed Pneumocystis carinii pneumonia in June 1993. In February 1994, and developed cytomegalovirus retinitis and died 6 months later. Donor blood given to the patients during the hysterectomy was HIV-1 positive. The donor's HIV infection was discovered in 1991 and he died of AIDS in 1993. As blood centers in Taiwan did not start screening for HIV-1 until January 1988, it is urgently recommended that any individual who received a blood transfusion between 1984 and 1987 in Taiwan and who currently experiences repeated episodes of opportunistic infections have an HIV-1 blood test. The receipt of a blood transfusion between 1984 and 1987 should be listed by the Department of Health as an indication for HIV-1 screening.

Simulated Brown syndrome is a term applied to a myriad of disorders that cause a Brown syndrome-like motility. We encountered a case of acquired simulated Brown syndrome in a 41-year-old man following surgical repair of fractures of both medial orbital walls. He suffered from diplopia in primary gaze, associated with hypotropia of the affected eye. We performed an ipsilateral recession of the left inferior rectus muscle as a single-stage intraoperative adjustment procedure under topical anesthesia, rather than the direct approach to the superior oblique tendon. Postoperatively, the patient was asymptomatic in all diagnostic gaze positions.

Human Immunodeficiency Virus Proteins Mimic Human T Cell Receptors Inducing Cross-Reactive Antibodies

PubMed Central

2017-01-01

Human immunodeficiency virus (HIV) hides from the immune system in part by mimicking host antigens, including human leukocyte antigens. It is demonstrated here that HIV also mimics the V-β-D-J-β of approximately seventy percent of about 600 randomly selected human T cell receptors (TCR). This degree of mimicry is greater than any other human pathogen, commensal or symbiotic organism studied. These data suggest that HIV may be evolving into a commensal organism just as simian immunodeficiency virus has done in some types of monkeys. The gp120 envelope protein, Nef protein and Pol protein are particularly similar to host TCR, camouflaging HIV from the immune system and creating serious barriers to the development of safe HIV vaccines. One consequence of HIV mimicry of host TCR is that antibodies against HIV proteins have a significant probability of recognizing the corresponding TCR as antigenic targets, explaining the widespread observation of lymphocytotoxic autoantibodies in acquired immunodeficiency syndrome (AIDS). Quantitative enzyme-linked immunoadsorption assays (ELISA) demonstrated that every HIV antibody tested recognized at least one of twelve TCR, and as many as seven, with a binding constant in the 10−8 to 10−9 m range. HIV immunity also affects microbiome tolerance in ways that correlate with susceptibility to specific opportunistic infections. PMID:28972547

Hematopoietic stem cell transplantation is a promising curative therapy for many combined primary immunodeficiencies and phagocytic disorders. We retrospectively reviewed pediatric cases of patients diagnosed with primary immunodeficiencies and scheduled for hematopoietic stem cell transplantation. We identified 22 patients (median age, 6 months; age range, 1 month to 10 years) with various diagnoses who received hematopoietic stem cell transplantation. The patient diagnoses included severe combined immunodeficiency (n=11), Chediak-Higashi syndrome (n=2), leukocyte adhesion deficiency (n=2), MHC class 2 deficiency (n=2), chronic granulomatous syndrome (n=2), hemophagocytic lymphohistiocytosis (n=1), Wiskott-Aldrich syndrome (n=1), and Omenn syndrome (n=1). Of the 22 patients, 7 received human leukocyte antigen-matched related hematopoietic stem cell transplantation, 12 received haploidentical hematopoietic stem cell transplantation, and 2 received matched unrelated hematopoietic stem cell transplantation. The results showed that 5 patients had graft failure. Fourteen patients survived, yielding an overall survival rate of 67%. Screening newborn infants for primary immunodeficiency diseases may result in timely administration of hematopoietic stem cell transplantation.

Tissues from 34 naturally feline immunodeficiency virus (FIV)-infected cats, 13 asymptomatic cats and 21 cats with signs of feline acquired immunodeficiency syndrome (F-AIDS), and 35 FIV-seronegative subjects were examined to determine the presence of amyloid deposits. Twenty experimentally FIV-infected cats and five specific pathogen-free (SPF) control cats were also included in the study. Paraffin-embedded sections from kidney and other organs were submitted to histological and histochemical analysis. Amyloid deposits were identified by a modified Congo red stain and confirmed by electron microscopy to demonstrate the presence of amyloid fibrils in amyloid positive glomeruli. In all positive cases, secondary amyloidosis was identified with potassium permanganate pretreatment and amyloid type was further characterised by immunohistochemistry using primary antibodies against human AA and feline AL amyloids. Amyloid deposits were present in different tissues of 12/34 (35%) naturally FIV-infected cats (seven presenting F-AIDS and five in asymptomatic phase) and in 1/30 FIV-seronegative cats. All the experimentally FIV-infected and SPF subjects showed no amyloid deposits. Amyloidosis has been reported in human lentiviral infections, and the data reported here demonstrate the need, in naturally FIV-infected cats, to consider the presence of amyloidosis in differential diagnosis of hepatic and renal disorders to better assess the prognosis of the disease.

A 53-year-old female developed epigastric discomfort and back pain in 2007. Diagnostic imaging studies demonstrated a soft tissue tumor with heterogeneous enhancement in the anterior mediastinum and multiple nodules in the right lung. She underwent expanded thymectomy with subtotal resection of the right lung. The pathological diagnosis was primary thymic mucosa-associated lymphoid tissue (MALT) lymphoma. The patient complained of ocular discomfort, oral dryness and continuous nasal bleeding in 2007. Detailed examination led to a diagnosis of Sjögren syndrome and acquired von Willebrand syndrome. Rituximab treatment for residual disease achieved not only a reduction of the lung MALT lymphoma but also clinical and hematological remission of both syndromes. This is, to our knowledge, the first reported case of primary thymic MALT lymphoma accompanied by Sjögren and acquired von Willebrand syndromes.

Moral beliefs of physicians, medical students, clergy, and lay public concerning AIDS.

1989-01-01

A questionnaire was developed to assess religiously based moral beliefs about acquired immunodeficiency syndrome. The questionnaire was administered to a group of primarily black physicians, a selection of freshman medical students, two groups of clergy representing contrasting philosophical orientations, a group of young urban black and white attendees of a black cultural event, and two groups of older whites from rural Tennessee who were attending health fairs. Other attitudes about acquired immunodeficiency syndrome and related issues were also assessed. Results showed that 40% to 70% of rural whites strongly endorsed the idea that acquired immunodeficiency syndrome is a product of "divine intervention" or "divine retribution." More than half attributed the epidemic to a fulfillment of biblical prophecy. Two of five conservative clergy strongly agreed with the idea of divine intervention, whereas only one in 20 liberal clergy concurred. Approximately one in 10 physicians endorsed these propositions. The responses of freshman medical students were strikingly similar to those of physicians, except that less than half as many believed acquired immunodeficiency syndrome represents the fulfillment of a biblical prophecy. Physicians were remarkably similar to rural whites and conservative clergy in their distrust of the experts concerning the potential contagion of human immunodeficiency virus. When responses to several key items on the questionnaire were combined to create a measure of "conservatism," mean total scores differentiated all groups in the manner predicted. We conclude that religiously based moral beliefs about acquired immunodeficiency syndrome can have dangerous implications for the treatment of its victims by society and its caregivers.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2621750

The survival of patients with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) who have access to highly active antiretroviral therapy (ART) has dramatically increased in recent times. This review focuses on HIV-associated heart failure in sub-Saharan Africa (SSA). In HIV infected persons, heart failure may be related to pathology of the pericardium, the myocardium, the valves, the conduction system, or the coronary and pulmonary vasculature. HIV-associated heart failure can be because of direct consequences of HIV infection, autoimmune reactions, pro-inflammatory cytokines, opportunistic infections (OIs) or neoplasms, use of ART or therapy for OIs and presence of traditional cardiovascular risk factors. Myocardial involvement includes diastolic dysfunction, asymptomatic left ventricular dysfunction, cardiomyopathy, myocarditis, fibrosis, and steatosis. Pericardial diseases include pericarditis, pericardial effusions (rarely causing tamponade), pericardial constriction, and effusive-constrictive syndromes. Coronary artery disease is commonly reported in industrial nations, although its prevalence is thought to be low in HIV-infected persons from SSA. © 2016 The Authors.

We prospectively evaluated potential markers and cofactors for the acquired immunodeficiency syndrome (AIDS) in 86 homosexual men who were seropositive for human immunodeficiency virus antibodies. During three years of follow-up, 19 men developed AIDS. Risk of AIDS was clearly predicted by the total number of circulating OKT4-positive lymphocytes (T4 count) at enrollment, while the corresponding T8 count was unrelated to subsequent AIDS development. Subjects in Manhattan had a higher risk of Kaposi's sarcoma than did subjects in Washington, DC, and the risk of AIDS tended to increase with numerous homosexual partners. Several of 40 potential cofactors defined ex post facto, including receptive fellatio, enemas, methaqualone use, and high levels of antibody to hepatitis B surface antigen, appeared to be associated with Kaposi's sarcoma but not with Pneumocystis pneumonia. Our data suggest that potent cofactors for Pneumocystis pneumonia were not prominent, pointing to the need for effective drug therapies, particularly to reduce the high AIDS risk of persons with human immunodeficiency virus infection and low T4 counts.

1997-05-01

The purpose of this study was to determine the prevalence of upper gastrointestinal tract lesions in children with human immunodeficiency virus (HIV) infection who undergo endoscopy of the upper gastrointestinal tract and to identify important clinical predictors of abnormal endoscopic results. All HIV-infected children who underwent endoscopy and were followed at Children's Hospital, Boston, from January 1985 to August 1994 were studied. The main outcome measure was endoscopic results, which were categorized into observational, histologic, and microbiologic findings. Potential predictors included height, weight, nutritional interventions, HIV disease stage, CD4 T-lymphocyte count, medications, active infections, and indications for endoscopy. Forty-three endoscopies in unique patients are reported. Most children had advanced HIV infection (67% acquired immunodeficiency syndrome, mean CD4 T-lymphocyte count z score = -2.71, weight z score = -2.04). An abnormal endoscopic finding was discovered in 93% of children and confirmed by histologic, microbiologic, or a combination of these studies in 72% of children. Thirty-five percent of children had an opportunistic pathogen identified endoscopically; 65% of these pathogens were previously undiagnosed. Observational findings often were poor indicators of histologic and microbiologic abnormalities. Independent predictors of abnormal histologic findings include younger age at endoscopy (odds ratio (OR) = 1.16 per year, 95% confidence interval (CI) (1.02, 1.33)) and guaiac-negative stools (OR = 16.7, 95% CI (1.92, 142.9)). Independent predictors of finding a pathogen at the time of endoscopy include a greater number of indications for endoscopy (OR = 2.6 per indication, 95% CI (1.3, 5.3)) and diagnosis of acquired immunodeficiency syndrome (OR = 16.4, 95% CI (1.3, 213)). No other gastrointestinal, nutritional, or immunologic parameters were significantly predictive of endoscopic outcomes. Medical management was changed in

Human immunodeficiency virus-associated disruption of mucosal barriers and its role in HIV transmission and pathogenesis of HIV/AIDS disease

Tugizov, Sharof

2016-01-01

Abstract Oral, intestinal and genital mucosal epithelia have a barrier function to prevent paracellular penetration by viral, bacterial and other pathogens, including human immunodeficiency virus (HIV). HIV can overcome these barriers by disrupting the tight and adherens junctions of mucosal epithelia. HIV-associated disruption of epithelial junctions may also facilitate paracellular penetration and dissemination of other viral pathogens. This review focuses on possible molecular mechanisms of HIV-associated disruption of mucosal epithelial junctions and its role in HIV transmission and pathogenesis of HIV and acquired immune deficiency syndrome (AIDS).

Alcohol use negatively affects adherence to antiretroviral therapy (ART), thus human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) care providers need accurate, efficient assessments of alcohol use. Using existing data from an efficacy trial of 2 cognitive-behavioral ART adherence interventions, the authors sought to determine if results on 2 common alcohol screening tests (Alcohol Use Disorders Identification Test--Consumption [AUDIT-C] and its binge-related question [AUDIT-3]) predict ART nonadherence. Twenty-seven percent of the sample (n = 308) were positive on the AUDIT-C and 34% were positive on the AUDIT-3. In multivariate analyses, AUDIT-C-positive status predicted ART nonadherence after controlling for race, age, conscientiousness, and self-efficacy (P = .036). Although AUDIT-3-positive status was associated with ART nonadherence in unadjusted analyses, this relationship was not maintained in the final multivariate model. The AUDIT-C shows potential as an indirect screening tool for both at-risk drinking and ART nonadherence, underscoring the relationship between alcohol and chronic disease management.

Since 1980 more than 25 million people have died from acquired immunodeficiency syndrome (AIDS), which results from infection with human immunodeficiency virus (HIV). Number of new cases increases very threateningly. One and the most effective method to stop the progress of epidemic is the development of the vaccine for HIV. There is the presentation of the first stage of the vaccine for HIV testing (structure, methodology), which is now on trial in St. Pierre hospital, Brussels University. HIV characteristics which inflame the process of the vaccine development, historical facts and facts about vaccines on trial in these days are reviewed in this article. More than 10,000 volunteers have been participating in various clinical trials since 1987. The development of the vaccine is a very difficult, long-terming (about 8-10 years) and costly process. The process of the vaccine testing is very difficult in developing countries where the infection spreads the most rapidly. Available data confirm that the vaccine must be multi-componential, inducing cellular, humoral immunity against various subtypes of HIV. The vaccine cannot protect fully but the changes of the natural infection course could decrease virulence, distance the stage of AIDS, and retard the spread of the epidemic.

Infection of pig-tailed macaques with the simian immunodeficiency virus (SIV) isolate SIVsmmFGb frequently results in SIV encephalitis (SIVE) in addition to immunodeficiency and acquired immune deficiency syndrome. We used in situ hybridization to quantitate the number of SIV-infected cells in brain parenchyma, choroid plexus, and meninges from 17 macaques that developed acquired immune deficiency syndrome after infection with SIVsmmFGb. SIV-infected cells and histopathological lesions of SIVE were identified in 15 of 17 animals (88.2%), including 12 of 12 rapid progressors (RP) and 3 of 5 slow progressors (SP). The parenchymal virus burden was much greater in RP macaques than in the three SP macaques with SIVE (median values of 24.3 versus 0.3 infected cells/mm2, respectively; P < 0.05). Viral load differences between RP and SP with SIVE were less marked in choroid plexus (29.6 versus 12.8 infected cells/mm2, respectively) and meninges (133.0 versus 34.2 infected cells/mm2, respectively). A significant negative correlation was observed between the magnitude of the anti-SIV antibody titer at 1 month after inoculation and brain virus burden at necropsy (r = −0.614; P < 0.01). The close association between immune response and SIVE in this model should prove useful for identifying correlates of immune protection against primate lentiviral encephalitis. PMID:15039205

Virulence of Rhodococcus equi strains from 20 humans in Brazil was investigated by using a polymerase chain reaction to characterize isolates as virulent (VapA), intermediately virulent (VapB), and avirulent. Nine isolates were obtained from human immunodeficiency virus (HIV)–positive patients, six from HIV-negative patients, and five from patients of unknown status. Five isolates were VapB positive, four were VapA positive, and eleven were avirulent. Among the nine isolates from HIV-positive patients, five contained VapB plasmids and two contained VapA plasmids. Five VapB-positive isolates had the type 8 virulence plasmid. Eleven of the patients had a history of contact with livestock and/or a farm environment, and none had contact with pigs. PMID:21896813

Targeting cysteine residues of human immunodeficiency virus type 1 protease by reactive free radical species.

PubMed

Basu, A; Sehajpal, P K; Ogiste, J S; Lander, H M

1999-01-01

Nitric oxide (NO) is a naturally occurring free radical with many functions. The oxidized form of NO, the nitrosonium ion, reacts with the thiol group of cysteine residues resulting in their modification to S-nitrosothiols. The human immunodeficiency virus type 1 (HIV-1) protease (HIV-PR) has two cysteine residues that are conserved amongst different viral isolates found in patients with acquired immunodeficiency syndrome (AIDS). In an active dimer, these residues are located near the surface of the protease. We have found that treatment of HIV-PR with different NO congeners results in loss of its proteolytic activity and simultaneous formation of S-nitrosothiols. Sodium nitroprusside inhibited HIV-PR up to 70% and S-nitroso-N-acetylpenicillamine completely inhibited the protease within 5 min of treatment. The pattern of inhibition by NO donors is comparable to its inhibition by N-acetyl pepstatin. Using electrospray ionization-mass spectrometry, we identified the modification of HIV-PR by NO as that of S-nitrosation. Our findings point towards a possible role of NO in mediating resistance to HIV-1 infection.

Acquired pendular nystagmus

Acquired pendular nystagmus is comprised of quasi-sinusoidal oscillations of the eyes significantly affecting gaze holding and clarity of vision. The most common causes of acquired pendular nystagmus include demyelinating disorders such as multiple sclerosis and the syndrome of ocular palatal tremor. However, several other deficits, such as pharmacological intoxication, metabolic and genetic disorders, and granulomatous disorders can lead to syndromes mimicking acquired pendular nystagmus. Study of the kinematic features of acquired pendular nystagmus has suggested a putative pathophysiology of an otherwise mysterious neurological disorder. Here we review clinical features of neurological deficits that co-occur with acquired pendular nystagmus. Subsequent discussion of the pathophysiology of individual forms of pendular nystagmus speculates on mechanisms of the underlying disease while providing insights into pharmacotherapy of nystagmus.

Highly active antiretroviral therapy (HAART) restores inflammatory immune responses in AIDS patients which may unmask previous subclinical infections or paradoxically exacerbate symptoms of opportunistic infections. In resource-poor settings, 25% of patients receiving HAART may develop CNS-related immune reconstitution inflammatory syndrome (IRIS). Here we describe a reliable mouse model to study underlying immunopathological mechanisms of CNS-IRIS. Utilizing our HSV brain infection model and mice with MAIDS, we investigated the effect of immune reconstitution on MAIDS mice harboring opportunistic viral brain infection. Using multi-color flow cytometry, we quantitatively measured the cellular infiltrate and microglial activation. Infection with the LP-BM5 retroviral mixture was found to confer susceptibility to herpes simplex virus (HSV)-1 brain infection to normally-resistant C57BL/6 mice. Increased susceptibility to brain infection was due to severe immunodeficiency at 8 wks p.i. and a marked increase in programmed death-1 (PD-1) expression on CD4+ and CD8+ T-cells. Both T-cell loss and opportunistic brain infection were associated with high level PD-1 expression because PD-1-knockout mice infected with LP-BM5 did not exhibit lymphopenia and retained resistance to HSV-1. In addition, HSV-infection of MAIDS mice stimulated peripheral immune cell infiltration into the brain and its ensuing microglial activation. Interestingly, while opportunistic herpes virus brain infection of C57BL/6 MAIDS mice was not itself lethal, when T-cell immunity was reconstituted through adoptive transfer of virus-specific CD3+ T-cells, it resulted in significant mortality among recipients. This immune reconstitution-induced mortality was associated with exacerbated neuroinflammation, as determined by MHC class II expression on resident microglia and elevated levels of Th1 cytokines in the brain. Taken together, these results indicate development of an immune reconstitution disease

Human Immunodeficiency Virus Playing Hide-and-Seek: Understanding the TFH Cell Reservoir and Proposing Strategies to Overcome the Follicle Sanctuary.

2017-01-01

Human immunodeficiency virus (HIV) infects millions of people worldwide, and new cases continue to emerge. Once infected, the virus cannot be cleared by the immune system and causes acquired immunodeficiency syndrome. Combination antiretroviral therapeutic regimen effectively suppresses viral replication and halts disease progression. The treatment, however, does not eliminate the virus-infected cells, and interruption of treatment inevitably leads to viral rebound. The rebound virus originates from a group of virus-infected cells referred to as the cellular reservoir of HIV. Identifying and eliminating the HIV reservoir will prevent viral rebound and cure HIV infection. In this review, we focus on a recently discovered HIV reservoir in a subset of CD4 + T cells called the follicular helper T (T FH ) cells. We describe the potential mechanisms for the emergence of reservoir in T FH cells, and the strategies to target and eliminate this viral reservoir.

We report 2 cases, in middle-aged women, of toxic shock syndrome due to Community-acquired methicillin-resistant Staphylococcus aureus via a vaginal portal of entry. The first patient had used a tampon and the second patient had vaginitis due to a cleft narrowing associated with vulvar lichen sclerosus. Both patients were admitted to our hospital with septic shock and severe acute kidney injury and subsequently recovered with appropriate antibiotic treatment. In our review of the literature, 8 cases of toxic shock syndrome caused by Community-acquired methicillin-resistant Staphylococcus aureus were reported in Japan. In these 8 cases, the main portals of entry were the skin and respiratory tract; however, the portal of entry of Community-acquired methicillin-resistant Staphylococcus aureus from a vaginal lesion has not been reported in Japan previously.

Acquired pendular nystagmus.

Acquired pendular nystagmus is comprised of quasi-sinusoidal oscillations of the eyes significantly affecting gaze holding and clarity of vision. The most common causes of acquired pendular nystagmus include demyelinating disorders such as multiple sclerosis and the syndrome of ocular palatal tremor. However, several other deficits, such as pharmacological intoxication, metabolic and genetic disorders, and granulomatous disorders can lead to syndromes mimicking acquired pendular nystagmus. Study of the kinematic features of acquired pendular nystagmus has suggested a putative pathophysiology of an otherwise mysterious neurological disorder. Here we review clinical features of neurological deficits that co-occur with acquired pendular nystagmus. Subsequent discussion of the pathophysiology of individual forms of pendular nystagmus speculates on mechanisms of the underlying disease while providing insights into pharmacotherapy of nystagmus.

This paper discusses the importance of oral lesions as indicators of infection with human immunodeficiency virus (HIV) and as predictors of progression of HIV disease to acquired immunodeficiency syndrome (AIDS). Oral manifestations are among the earliest and most important indicators of infection with HIV. Seven cardinal lesions, oral candidiasis, hairy leukoplakia, Kaposi sarcoma, linear gingival erythema, necrotizing ulcerative gingivitis, necrotizing ulcerative periodontitis and non-Hodgkin lymphoma, which are strongly associated with HIV infection, have been identified and internationally calibrated, and are seen in both developed and developing countries. They may provide a strong indication of HIV infection and be present in the majority of HIV-infected people. Antiretroviral therapy may affect the prevalence of HIV-related lesions. The presence of oral lesions can have a significant impact on health-related quality of life. Oral health is strongly associated with physical and mental health and there are significant increases in oral health needs in people with HIV infection, especially in children, and in adults particularly in relation to periodontal diseases. International collaboration is needed to ensure that oral aspects of HIV disease are taken into account in medical programmes and to integrate oral health care with the general care of the patient. It is important that all health care workers receive education and training on the relevance of oral health needs and the use of oral lesions as surrogate markers in HIV infection. PMID:16211162

Disseminated cryptococcosis and recurrent oral candidiasis was presented in a-heterosexual AIDS patient. Candida tropicalis (C.tropicalis) was isolated from the oral pseudomembranous plaques and Cryptococcus neoformans (C. neoformans) was isolated from maculopapular lesions on body parts (face, hands and chest) and body fluids (urine, expectorated sputum, and cerebrospinal fluid). In vitro drug susceptibility testing on the yeast isolates demonstrated resistance to fluconazole acquired by C. tropicalis which was a suggestive possible root cause of recurrent oral candidiasis in this patient.

The rapid emergence of AIDS in humans during the period between 1980 and 2000 has led to extensive efforts to understand more fully similar etiologic agents of chronic and progressive acquired immunodeficiency disease in several mammalian species. Lentiviruses that have gene sequence homology with human immunodeficiency virus (HIV) have been found in different species (including sheep, goats, horses, cattle, cats, and several Old World monkey species). Lentiviruses, comprising a genus of the Retroviridae family, cause persistent infection that can lead to varying degrees of morbidity and mortality depending on the virus and the host species involved. Feline immunodeficiency virus (FIV) causes an immune system disease in domestic cats (Felis catus) involving depletion of the CD4+ population of T lymphocytes, increased susceptibility to opportunistic infections, and sometimes death. Viruses related to domestic cat FIV occur also in a variety of nondomestic felids. This is a brief overview of the current state of knowledge of this large and ancient group of viruses (FIVs) in South America. PMID:22590677

Immune Dysregulation, Polyendocrinopathy, Enteropathy, X-Linked Syndrome: A Paradigm of Immunodeficiency with Autoimmunity

PubMed Central

Barzaghi, Federica; Passerini, Laura; Bacchetta, Rosa

2012-01-01

Immune dysregulation, polyendocrinopathy, enteropathy, X-linked (IPEX) syndrome is a rare monogenic primary immunodeficiency (PID) due to mutations of FOXP3, a key transcription factor for naturally occurring (n) regulatory T (Treg) cells. The dysfunction of Treg cells is the main pathogenic event leading to the multi-organ autoimmunity that characterizes IPEX syndrome, a paradigm of genetically determined PID with autoimmunity. IPEX has a severe early onset and can become rapidly fatal within the first year of life regardless of the type and site of the mutation. The initial presenting symptoms are severe enteritis and/or type-1 diabetes mellitus, alone or in combination with eczema and elevated serum IgE. Other autoimmune symptoms, such as hypothyroidism, cytopenia, hepatitis, nephropathy, arthritis, and alopecia can develop in patients who survive the initial acute phase. The current therapeutic options for IPEX patients are limited. Supportive and replacement therapies combined with pharmacological immunosuppression are required to control symptoms at onset. However, these procedures can allow only a reduction of the clinical manifestations without a permanent control of the disease. The only known effective cure for IPEX syndrome is hematopoietic stem cell transplantation, but it is always limited by the availability of a suitable donor and the lack of specific guidelines for bone marrow transplant in the context of this disease. This review aims to summarize the clinical histories and genomic mutations of the IPEX patients described in the literature to date. We will focus on the clinical and immunological features that allow differential diagnosis of IPEX syndrome and distinguish it from other PID with autoimmunity. The efficacy of the current therapies will be reviewed, and possible innovative approaches, based on the latest highlights of the pathogenesis to treat this severe primary autoimmune disease of childhood, will be discussed.

Patients with acquired immunodeficiency syndrome (AIDS) and AIDS-related complex (ARC) have hyperimmunoglobulinemia and increased numbers of circulating immunoglobulin-secreting cells. In this paper, we studied the basis for this B cell hyperactivity. Limiting dilution studies of B cells from seven patients with ARC and four with AIDS revealed that some B cells spontaneously produced antibodies to human T cell lymphotropic virus, type III/lymphadenopathy-associated virus (HTLV-III/LAV) (39:10(6) and 7:10(6) B cells, respectively), suggesting that chronic antigenic stimulation by HTLV-III/LAV was one contributing factor. The patients also had an increased number of spontaneously outgrowing B cells than did normals (6:10(6) vs. less than 2:10(6) B cells), suggesting that they had an increased number of Epstein-Barr virus (EBV)-infected B cells. However, fewer B cells from patients were immortalized by exogenously added EBV than were B cells from normals. In additional studies, HTLV-III/LAV induced immunoglobulin secretion (mean 2,860 ng/ml) by peripheral blood mononuclear cells from normals; this HTLV-III/LAV-induced immunoglobulin secretion required the presence of both B and T cells. Thus, antigenic stimulation by HTLV-III/LAV, increased numbers of EBV-infected B cells, and HTLV-III/LAV-induced T cell-dependent B cell activation all contribute to the B cell hyperactivity in patients with HTLV-III/LAV disease.

Talaromyces marneffei is a dimorphic fungus endemic mainly in southeast and south Asia. It causes severe mycosis, usually in immunocompromised individuals, such as those with human immunodeficiency virus (HIV) infection. Concomitant infection with T. marneffei and other opportunistic pathogens is plausible because the majority of T. marneffei infections occur in patients with advanced HIV infection. Nonetheless, coinfection in the same site has rarely been reported, and poses a considerable diagnostic and therapeutic challenge. We report the case of an HIV-infected Japanese patient who had lived in Thailand for 6 years. The patient developed T. marneffei and Mycobacterium tuberculosis coinfection, and both pathogens were isolated from the same sites: a blood specimen and a lymph node aspirate. Clinicians should be aware of concomitant infection with T. marneffei and other pathogens in patients with advanced HIV disease who are living in or who have visited endemic areas.

Role of mu-opioids as cofactors in human immunodeficiency virus type 1 disease progression and neuropathogenesis

About one third of acquired immunodeficiency syndrome cases in the USA have been attributed to the use of injected addictive drugs, frequently involving opioids like heroin and morphine, establishing them as significant predisposing risk factors for contracting human immuno-deficiency virus type 1 (HIV-1). Accumulating evidence from in vitro and in vivo experimental systems indicates that opioids act in concert with HIV-1 proteins to exacerbate dysregulation of neural and immune cell function and survival through diverse molecular mechanisms. In contrast, the impact of opioid exposure and withdrawal on the viral life cycle and HIV-1 disease progression itself is unclear, with conflicting reports emerging from the simian immunodeficiency virus and simian–human immunodeficiency virus infection models. However, these studies suggest a potential role of opioids in elevated viral production. Because human microglia, astrocytes, CD4+ T lymphocytes, and monocyte-derived macrophages express opioid receptors, it is likely that intracellular signaling events triggered by morphine facilitate enhancement of HIV-1 infection in these target cell populations. This review highlights the biochemical changes that accompany prolonged exposure to and withdrawal from morphine that synergize with HIV-1 proteins to disrupt normal cellular physiological functions especially within the central nervous system. More importantly, it collates evidence from epidemiological studies, animal models, and heterologous cell systems to propose a mechanistic link between such physiological adaptations and direct modulation of HIV-1 production. Understanding the opioid–HIV-1 interface at the molecular level is vitally important in designing better treatment strategies for HIV-1-infected patients who abuse opioids. PMID:21735315

Skin problems in immunodeficient patients.

PubMed

Itin, Peter H; Battegay, Manuel

2012-01-01

The most important function of the skin besides social communication is active protection against mechanical, chemical and microbial threat. The epidermis has biochemical, physical, immunological and anti-infective properties, and is the most important shield against aggressors. Chronic immunosuppression impairs this cutaneous quality and therefore numerous mucocutaneous complications can occur. The physiological colonization of commensal microbes helps to limit the expansion of pathogenic bacteria, viruses and fungi by a continuous release of antimicrobial peptides from keratinocytes. Genetic or acquired immunodeficiency influences these factors. Malignant neoplastic diseases such as leukemia or lymphomas can also lead to severe immunodeficiency. Drug-induced immunodeficiency is common in organ-transplanted patients with the aim to prevent organ rejection. Such patients with prolonged immunodeficiency often develop atypical presentations of mucocutaneous infections. This is the reason why such patients should be biopsied liberally. In addition to the conventional histology, a part of the biopsy should be used for microbiological cultures. Long-term complications of oncogenic viruses have to be considered leading to epithelial cancers (HPV), Kaposi sarcomas (HHV8), lymphomas (EBV) and Merkel cell tumor (polyomavirus) apart from more known acute infections of the skin. Important mucocutaneous markers of immunosuppression such as oral hairy leukoplakia, oral candidiasis and eczema molluscatum exist. This work reviews the pathophysiology of skin protection and describes typical mucocutaneous problems in immunosuppressed patients. Copyright © 2012 S. Karger AG, Basel.

Human immunodeficiency virus (HIV) infection is an epidemic worldwide, despite the marked benefits of antiretroviral therapy (ARV) in reducing severe HIV-associated dementia. A milder form of neurocognitive disorders are still prevalent and remain a challenge. This study aimed to determine the correlation between plasma cluster of differentiation 4 (CD4) lymphocyte, duration of ARV treatment, opportunistic infections, and cognitive function in HIV-AIDS patients. A cross-sectional study involving 85 HIV-AIDS patients was conducted at Adam Malik General Hospital Medan, Indonesia. All subjects were subjected to physical, neurologic examination and Montreal Cognitive Assessment-Indonesian Version (MoCA-INA) to assess cognitive function and measurement of lymphocyte CD4 counts. Out of the 85 subjects evaluated, the proportion concerning sexes include 52 males (61.2 %) and 33 females (38.8%). The mean age was 38.53 ± 9.77 years old. There was a significant correlation between CD4 lymphocyte counts and MoCA-INA score (r = 0.271, p = 0.012), but there was no significant correlation between duration of ARV treatment and MoCA-INA score. There was also no difference in MoCA-INA score based on the presence of opportunistic infection. Lymphocyte CD4 count was independently correlated with cognitive function in HIV-AIDS patients.

Recent data suggest that aminosugar derivatives which inhibit glycoprotein processing have potential anti-human immunodeficiency virus (HIV) activity. These inhibitory effects may be due to disruption of cell fusion and subsequent cell-cell transmission of the acquired immunodeficiency syndrome (AIDS) virus. Free virus particles able to bind CD4-positive cells are still produced in the presence of these compounds with only partial reduction of infectivity. We now report a method to score in parallel both the degree of antiviral activity and the effect on cell division of aminosugar derivatives. We find that (i) the compounds 1,4-dideoxy-1,4-imino-L-arabinitol and N-(5-carboxymethyl-1-pentyl)-1,5-imino-L-fucitol partially inhibit the cytopathic effect (giant cell formation, etc.) of HIV and yield of infectious virus; (ii) the compounds N-methyldeoxynojirimycin and N-ethyldeoxynojirimycin reduce the yield of infectious HIV by an order of four and three logarithms, respectively; and (iii) one compound, N-butyldeoxynojirimycin, of the 47 compounds previously screened reduces infectious viral particles by a logarithmic order greater than five at noncytotoxic concentrations. In addition, long-term growth of infected cells in the presence of N-butyldeoxynojirimycin gradually decreases the proportion of infected cells, leading to eventual elimination of HIV from culture. This result suggests that replication is associated with cytolysis. The ability to break the cycle of replication and reinfection has important implications in the chemotherapy of AIDS. PMID:3264071

Physicians, AIDS, and occupational risk. Historic traditions and ethical obligations.

PubMed

Zuger, A; Miles, S H

1987-10-09

The profound reluctance of some physicians to care for patients with acquired immunodeficiency syndrome prompted us to review medical responses to other historic plagues. No consistent professional tradition emerged. Many physicians, including Galen and Sydenham, fled from patients with contagious epidemic diseases. Many of their colleagues, at considerable personal risk, remained behind to care for plague victims. This inconsistency suggests that an ethic stressing traditional professional duties may not be ideal for defining the optimal relation of the medical profession to patients with acquired immunodeficiency syndrome. A new professional ethic to guide physicians in the acquired immunodeficiency syndrome pandemic is needed. This ethic cannot be entirely derived from these patients' right to health care, which is primarily a claim against society rather than individual practitioners. Civil and professional proscriptions against negligence or abandonment apply only to therapeutic relationships after they are contracted. However, a professional duty to treat human immunodeficiency virus-infected persons could be based on the understanding of medicine as a moral enterprise. In this context, treating human immunodeficiency virus-infected persons is a virtuous act, which meets both patients' and society's health needs and affirms the moral mission of health care.

Autoimmune cytopenia is a frequent manifestation of primary immunodeficiencies. Two siblings presented with Evans syndrome, viral infections, and progressive leukopenia. DNA available from one patient showed a homozygous frameshift mutation in tripeptidyl peptidase II (TPP2) abolishing protein expression. TPP2 is a serine exopeptidase involved in extralysosomal peptide degradation. Its deficiency in mice activates cell death programs and premature senescence. Similar to cells from naïve, uninfected TPP2-deficient mice, patient cells showed increased major histocompatibility complex I expression and most CD8+ T-cells had a senescent CCR7-CD127−CD28−CD57+ phenotype with poor proliferative responses and enhanced staurosporine-induced apoptosis. T-cells showed increased expression of the effector molecules perforin and interferon-γ with high expression of the transcription factor T-bet. Age-associated B-cells with a CD21− CD11c+ phenotype expressing T-bet were increased in humans and mice, combined with antinuclear antibodies. Moreover, markers of senescence were also present in human and murine TPP2-deficient fibroblasts. Telomere lengths were normal in patient fibroblasts and granulocytes, and low normal in lymphocytes, which were compatible with activation of stress-induced rather than replicative senescence programs. TPP2 deficiency is the first primary immunodeficiency linking premature immunosenescence to severe autoimmunity. Determination of senescent lymphocytes should be part of the diagnostic evaluation of children with refractory multilineage cytopenias. PMID:25414442

To study the characteristics of traditional Chinese medicine (TCM) syndrome factors of patients from different areas of China with human immunodeficiency virus (HIV) infection or acquired immunodeficiency syndrome (AIDS). A cross-sectional investigation study was conducted in Henan, Guangdong and Yunnan Provinces and Xinjiang Uygur Autonomous Region of China from October 2008 to August 2010. Based on literature review and expert opinion, a clinical questionnaire of TCM syndromes was drawn up. This survey was carried out after the investigators were professionally trained. Wenfeng III Auxiliary Diagnosis and Treat System of TCM was used to analyze the frequencies of AIDS patients' signs and symptoms with scores above 70 of syndrome factors respectively. Based on this work, syndrome factors of AIDS were analyzed in different areas. There were 608 HIV/AIDS cases investigated from October 2008 to August 2010 in total; among them, 276 cases were from Henan, 126 cases from Guangdong, 120 cases from Xinjiang and 86 cases from Yunnan. The results of syndrome factor analysis indicated that the syndromes of four provinces were similar. HIV/AIDS patients in the four areas exhibited qi deficiency, blood deficiency, yin deficiency, yang deficiency, dampness, phlegm, qi stagnation and essence deficiency syndromes. Patients in each area also had their own characteristics, such as that the scores of dampness of Guangdong and yin deficiency of Xinjiang were higher than the other syndromes, whereas the scores of Henan Province were higher than the other areas. AIDS patients had higher scores of syndromes than HIV-infected patients. HIV/AIDS patients from different areas had similar syndrome elements. The theory of "AIDS toxin injuring primordial qi" can sum up the TCM etiology and pathogenesis of HIV/AIDS.

Prevalence of risk factors for human immunodeficiency virus infection in the Australian population.

A random, stratified sample of 2601 adult Australians from all states and territories was interviewed about knowledge of the acquired immunodeficiency syndrome (AIDS). After the interview, an anonymous questionnaire on the prevalence of practices that are associated with risk of human immunodeficiency virus (HIV) infection was left with the respondents; 60.2% of these questionnaires were returned. Data from this survey suggest that the prevalences of male homosexual behaviour, prostitute contact and lesbian contact are substantially lower than were estimated previously. Men with homosexual experience were significantly more prevalent in the more populous states, but the majority of other risk factors--intravenous drug abuse, male respondents' contact with prostitutes, transfusion of blood or blood products during 1980-1985 and heterosexual contact--showed few significant associations with geographical, occupational or marital status. Intravenous drug abusers were significantly younger, and heterosexual contact was associated with age for both male and female respondents. No significant differences were found in the prevalence of homosexual contact among single, married and previously-married men, although the prevalence of homosexual contact was lower in married men. The results of the study are discussed in terms of targeting preventive campaigns and assessing the future potential for the spread of HIV infection.

The Human Immunodeficiency Virus (HIV) pandemic is on the increase with the highest burden in sub-Saharan Africa. This descriptive cross-sectional study was carried out in 2008 to assess the knowledge, self-perception of risk of contracting HIV infection and risky sexual practices among patients attending some out-patient clinics at the University Teaching Hospital, Ado-Ekiti, Ekiti State, Nigeria. The knowledge on the modes of transmission and methods of prevention of HIV was high. Although, 53.0% of the study participants perceived themselves not to be at risk of contracting HIV infection, 80.6% were engaged in risky sexual practices within a year preceding the study. Significantly more participants with multiple sexual partners, past and present history of Sexually Transmitted Infections (STI) perceived themselves not to be at risk (P= 0.001, 0.008 and 0.001 respectively). Effective strategies must therefore be developed, to enhance risk-perception since poor risk-perception is known to mitigate behavioral change.

Background Familial sick sinus syndrome is associated with gene mutations and dysfunction of ion channels. In contrast, degenerative fibrosis of the sinus node tissue plays an important role in the pathogenesis of acquired sick sinus syndrome. There is a close relationship between transforming growth factor-β1 mediated cardiac fibrosis and acquired arrhythmia. It is of interest to examine whether transforming growth factor-β1 is involved in the pathogenesis of acquired sick sinus syndrome. Methods Overall, 110 patients with acquired SSS and 137 age/gender-matched controls were screened for transforming growth factor-β1 and cardiac sodium channel gene polymorphisms using gene sequencing or restriction fragment length polymorphism methods. An enzyme-linked immunosorbent assay was used to determine the serum level of transforming growth factor-β1. Results Two transforming growth factor-β1 gene polymorphisms (C-509T and T+869C) and one cardiac sodium channel gene polymorphism (H588R) have been identified. The C-dominant CC/CT genotype frequency of T869C was significantly higher in acquired sick sinus syndrome patients than in controls (OR 2.09, 95% CI 1.16–3.75, P = 0.01). Consistently, the level of serum transforming growth factor-β1 was also significantly greater in acquired sick sinus syndrome group than in controls (5.3±3.4 ng/ml vs. 3.7±2.4 ng/ml, P = 0.01). In addition, the CC/CT genotypes showed a higher transforming growth factor-β1 serum level than the TT genotype (4.25 ± 2.50 ng/ml vs. 2.71± 1.76 ng/ml, P = 0.028) in controls. Conclusion Transforming growth factor-β1 T869C polymorphism, correlated with high serum transforming growth factor-β1 levels, is associated with susceptibility to acquired sick sinus syndrome.

[Neural mechanism underlying autistic savant and acquired savant syndrome].

Takahata, Keisuke; Kato, Motoichiro

It is well known that the cases with savant syndrome, demonstrate outstanding mental capability despite coexisting severe mental disabilities. In many cases, savant skills are characterized by its domain-specificity, enhanced memory capability, and excessive focus on low-level perceptual processing. In addition, impaired integrative cognitive processing such as social cognition or executive function, restricted interest, and compulsive repetition of the same act are observed in savant individuals. All these are significantly relevant to the behavioral characteristics observed in individuals with autistic spectrum disorders (ASD). A neurocognitive model of savant syndrome should explain these cognitive features and the juxtaposition of outstanding talents with cognitive disabilities. In recent neuropsychological studies, Miller (1998) reported clinical cases of "acquired savant," i.e., patients who improved or newly acquired an artistic savant-like skill in the early stage of frontotemporal dementia (FTD). Although the relationship between an autistic savant and acquired savant remains to be elucidated, the advent of neuroimaging study of ASD and the clarification of FTD patients with savant-like skills may clarify the shared neural mechanisms of both types of talent. In this review, we classified current cognitive models of savant syndrome into the following 3 categories. (1) A hypermnesic model that suggests that savant skills develop from existing or dormant cognitive functions such as memory. However, recent findings obtained through neuropsychological examinations imply that savant individuals solve problems using a strategy that is fairly different from a non-autistic one. (2) A paradoxical functional facilitation model (Kapur, 1996) that offers possible explanations about how pathological states in the brain lead to development of prodigious skills. This model emphasizes the role of reciprocal inhibitory interaction among adjacent or distant cortical regions

Purpose To update information on cytomegalovirus (CMV) retinitis in patients with the acquired immune deficiency syndrome (AIDS) and to integrate information on its pathogenesis and clinical outcomes. Design Literature review. Methods Selected articles from the medical literature, particularly large epidemiologic studies, including the Johns Hopkins Cytomegalovirus Retinitis Cohort Study, the Longitudinal Study of the Ocular Complications of AIDS, and the Cytomegalovirus Retinitis and Viral Resistance Study, were reviewed. Clinical information is discussed in light of knowledge on CMV, its pathogenesis, and its interactions with human immunodeficiency virus (HIV). Results Cytomegalovirus uses several mechanisms to evade the immune system and establish latent infection in immunologically normal hosts. With immune deficiency, such as late-stage AIDS, CMV reactivates, is disseminated to the eye, and establishes a productive infection, resulting in retinal necrosis. HIV and CMV potentiate each other: CMV accelerates HIV disease, and CMV retinitis is associated with increased mortality. Randomized clinical trials have demonstrated the efficacy of treatments for CMV retinitis. Systemically-administered treatment for CMV retinitis decreases AIDS mortality. Highly active antiretroviral therapy (HAART), effectively suppresses HIV replication, resulting in immune recovery, which, if sufficient, controls retinitis without anti-CMV therapy. Resistant CMV, detected in the blood, correlates with resistant virus in the eye and is associated with worse clinical outcomes, including mortality. Host factors, including host genetics and access to care, play a role in the development of CMV retinitis. Conclusions Clinical outcomes of CMV retinitis in patients with AIDS are dependent on characteristics of the virus and host and on HIV–CMV interactions. PMID:21168815

To estimate the influence of human immunodeficiency virus (HIV) infection and antiretroviral therapy on maternal serum markers levels and the false-positive rate with biochemical maternal serum screening for Down syndrome. We performed a 1:1 matched case-control study comparing 132 HIV-infected women with single pregnancy to controls selected among non-HIV-infected women matched on geographical origin and fetal sex. Of HIV-infected women, 47.7% were receiving antiretroviral therapy. Groups did not differ in multiples of the median (MoM) levels of total human chorionic gonadotrophin. The MoM alpha fetoprotein level did not differ between total HIV-infected women and control women but was significantly lower for untreated HIV-positive women compared with control women (0.91 compared with 1.03 MoM, P<.01) and compared with treated HIV-positive women (0.91 compared with 1.18 MoM, P<.01). The false-positive rate of biochemical screening did not differ between groups. Untreated HIV infection is associated with lower maternal serum alpha fetoprotein levels. Nevertheless, the false-positive rate of double-marker second-trimester Down syndrome serum screening did not appear to be affected in our sample of HIV-infected women, whether women were receiving antiretroviral therapy at the time of the test or not.

Dyskeratosis congenita (DC) is a heterogeneous inherited bone marrow failure and cancer predisposition syndrome in which germline mutations in telomere biology genes account for approximately one-half of known families. Hoyeraal Hreidarsson syndrome (HH) is a clinically severe variant of DC in which patients also have cerebellar hypoplasia and may present with severe immunodeficiency and enteropathy. We discovered a germline autosomal recessive mutation in RTEL1, a helicase with critical telomeric functions, in two unrelated families of Ashkenazi Jewish (AJ) ancestry. The affected individuals in these families are homozygous for the same mutation, R1264H, which affects three isoforms of RTEL1. Each parent was a heterozygous carrier of one mutant allele. Patient-derived cell lines revealed evidence of telomere dysfunction, including significantly decreased telomere length, telomere length heterogeneity, and the presence of extra-chromosomal circular telomeric DNA. In addition, RTEL1 mutant cells exhibited enhanced sensitivity to the interstrand cross-linking agent mitomycin C. The molecular data and the patterns of inheritance are consistent with a hypomorphic mutation in RTEL1 as the underlying basis of the clinical and cellular phenotypes. This study further implicates RTEL1 in the etiology of DC/HH and immunodeficiency, and identifies the first known homozygous autosomal recessive disease-associated mutation in RTEL1.

We sought to determine the prevalence and clinical and laboratory associations of fibromyalgia in adults with primary immunodeficiency (immunoglobulin (Ig) G subclass deficiency (IgGSD) and common variable immunodeficiency (CVID). We performed a retrospective analysis of these observations in 300 non-Hispanic white adult index patients with recurrent/severe respiratory tract infections and IgGSD or CVID: age; sex; IgGSD; fibromyalgia; chronic fatigue; autoimmune conditions (ACs); interstitial cystitis (IC); diabetes; body mass index; serum Ig isotypes; blood lymphocytes and subsets; and human leukocyte antigen (HLA)-A and -B types and haplotypes. We performed univariate comparisons, logistic multivariable regressions, and an analysis of covariance. Mean age was 49 ± 12 (standard deviation) y. There were 246 women (82.0%). IgGSD was diagnosed in 276 patients (92.0%). Fifty-six patients had fibromyalgia (18.7%; female:male 13:1). Other characteristics included: chronic fatigue, 63.0%; aggregate ACs, 35.3%; Sjögren's syndrome, 8.0%; IC, 3.0%; diabetes, 10.3%; and HLA-A*29, B*44 positivity, 9.7%. Prevalences of female sex; chronic fatigue; IC; and HLA-A*29, B*44 positivity were greater in patients with fibromyalgia. Logistic regression on fibromyalgia revealed three positive associations: chronic fatigue (p=0.0149; odds ratio 2.6 [95% confidence interval 1.2, 5.6]); Sjögren's syndrome (p=0.0004; 5.2 [2.1, 13.2]); and IC (p=0.0232; 5.7 [1.3, 25.7]). In an analysis of covariance, there were significant interactions of chronic fatigue, Sjögren's syndrome, and interstitial cystitis on fibromyalgia. Fibromyalgia is common in non-Hispanic white adult index patients with primary immunodeficiency, especially women. Chronic fatigue, Sjögren's syndrome, and IC are significantly associated with fibromyalgia after adjustment for other independent variables.

Human immunodeficiency virus (HIV) infection can cause a broad spectrum of renal diseases. However, there is paucity of Indian data on the patterns of renal lesions in HIV-seropositive patients. The aim of the present study was to delineate the spectrum of renal lesions in HIV/acquired immunodeficiency syndrome patients. In this prospective study, all HIV-positive patients of both genders aged >18 years were screened for renal disease. Patients with proteinuria of more than 1 g/24 h were subjected to renal biopsy. A total of 293 HIV-positive patients were screened; of these, 136 (46.4%) patients found to have renal involvement. Dipstick-positive proteinuria of 1+ or more was observed in 112 (38.2%) patients, and 16 (14.2%) patients had proteinuria of more than 1 g/24 h. Renal biopsy in 14 cases revealed glomerulonephritis (GN) in 12 (85.7%) (isolated GN in 4 [28.5%] and GN mixed with chronic TIN in 8 [57.1%]) patients. These include mesangioproliferative GN in 5 (35.7%), membranoproliferative GN in 2 (14.2%), focal segmental glomerulosclerosis in 2 (14.2%), diffuse proliferative GN in 2 (14.2%), and diabetic nephropathy in 1 (7.1%) patients. Chronic interstitial nephritis was noted in 10 (71.42%) (superimposed on GN in 8 [57.1%], isolated in 2 [14.2%]) patients. Granulomatous interstitial nephritis was seen in 3 (24.1%) cases. GN and chronic interstitial nephritis were noted in 85.7% and 71.42% of patients, respectively, mostly superimposed on each other. Mesangioproliferative GN was the most common glomerular lesion, but classical HIV-associated nephropathy was not observed.

Background Primary immunodeficiency (PID) is a cluster of serious disorders that requires special alertness on the part of the medical staff for prompt diagnosis and management of the patient. This study explored PID knowledge and experience among pediatricians of wide educational backgrounds, practicing in the United Arab Emirates (UAE). Method A self-administered questionnaire was used to determine the competency of pediatricians in their knowledge of PID disorders. This study questionnaire included questions on PID signs and symptoms, syndromes associated with immunodeficiency, screening tests, interpreting laboratory tests and case management. The participants were 263 pediatricians of diverse education working in the 27 governmental hospitals in all regions of UAE. Results The overall performance of the pediatricians did not differ based on their age, gender, origin of certification, rank, or years of experience. Of the 50 questions, 20% of pediatricians answered correctly <60% of the questions, 76% answered correctly 60 to 79% of the questions, and 4% answered correctly ≥80% of the questions. Seventeen of the 19 PID signs and symptoms were identified by 55 to 97%. Four of 5 syndromes associated with immunodeficiency were identified by 50 to 90%. Appropriate screening tests were chosen by 64 to 96%. Attention to the laboratory reference range values as function of patient age was notably limited. Conclusions There was a noteworthy deficiency in PID work-up. Therefore, implementing effective educational strategies is needed to improve the competency of pediatricians to diagnose and manage PID disorders. PMID:22846098

The description of hepatic sinusoidal lesions in a significant number of acquired immunodeficiency syndrome (AIDS) patients prompted the authors to undertake an ultrastructural study of the sinusoidal barrier abnormalities during human immunodeficiency virus (HIV) infection, in order to compare these lesions with those described in other conditions and to discuss their possible origin. In a series of 29 patients with serologic evidence of HIV infection and liver abnormalities, 8 (28%) had sinusoidal lesions. Peliosis hepatis was present in 2 cases, and sinusoidal dilatation in 6. These patients were classified as follows: 3 AIDS, 4 AIDS-related complex, 1 unclassifiable. Ultrastructural lesions of the sinusoidal barrier were observed in all the cases. They closely mimicked the changes previously reported in peliotic and peliotic-like changes of various origins. A striking particularity was, however, the presence of numerous and hyperplastic sinusoidal macrophages. This work suggests that an injury of the endothelial cells, directly or indirectly related to the presence of HIV, may be incriminated in the pathogenesis of sinusoidal lesions during HIV infection.

Unlike cancer and other illnesses for which specialists provide the majority of care for affected individuals, care of those infected with human immunodeficiency virus (HIV) is provided by generalists and many different types of specialists. To assess the utility of a prescription tracking database in identifying low experience and high-experience providers of such care regardless of specialty, we mailed a survey to 1500 physicians identified as having written prescriptions for agents used in care of HIV-infected individuals in the year before the survey. We discovered that physicians who care for patients with acquired immunodeficiency syndrome (AIDS) in the United States come from a broad range of specialties and practice in a variety of settings. Self-report of experience with AIDS care in the prior year was strongly associated with the number of HIV-related prescriptions identified in the tracking information. Response rates were consistent with those of other surveys published in medical journals. This study suggests that prescription tracking databases can be used to identify the breadth of physician/subjects who provide care for patients with HIV infection.

Despite the high incidence of cognitive and motor impairment in acquired immunodeficiency syndrome (AIDS) patients, the mechanisms of AIDS-related central nervous system (CNS) pathology are not completely understood. Infection with simian immunodeficiency virus (SIV) in macaques provides an excellent model of AIDS, including human immunodeficiency virus (HIV)-induced CNS pathology and cognitive/behavioral impairment. Co-inoculation with two SIV strains, SIV/17E-Fr and SIV/DeltaB670, accelerates SIV CNS disease, producing SIV encephalitis in over 90% of pig-tailed macaques within 3 months. In the present study, this SIV model was employed to identify cellular and viral correlates of behavioral impairment following SIV infection. Measures of psychomotor speed (simple reaction time), fine motor control (bimanual motor task), and general motor activity (home cage movement) were all adversely affected by SIV disease. Prior to euthanasia, performance was significantly impaired in both a simple reaction time task in 6 of 12 monkeys and a bimanual motor task in 5 of 6 monkeys. All monkeys evaluated (11 of 11) showed significant reductions in spontaneous motor activity. Significant correlations were found between impaired performance on the bimanual motor test and axonal damage (accumulation of beta-amyloid precursor protein in the corpus callosum) as well as increased microglial activation and macrophage infiltration (levels of CD68 and Ham56 immunostaining). These results suggest that axonal damage is related to the behavioral impairment induced by infection with SIV. The axonal damage may result from neuroimmune responses, including microglial and macrophage activation. Therefore, axonal damage may be a morphologic manifestation of neuronal dysfunction that underlies development of behavioral impairment in HIV/SIV CNS infection.

Virulence of Rhodococcus equi strains from 20 humans in Brazil was investigated by using a polymerase chain reaction to characterize isolates as virulent (VapA), intermediately virulent (VapB), and avirulent. Nine isolates were obtained from human immunodeficiency virus (HIV)-positive patients, six from HIV-negative patients, and five from patients of unknown status. Five isolates were VapB positive, four were VapA positive, and eleven were avirulent. Among the nine isolates from HIV-positive patients, five contained VapB plasmids and two contained VapA plasmids. Five VapB-positive isolates had the type 8 virulence plasmid. Eleven of the patients had a history of contact with livestock and/or a farm environment, and none had contact with pigs.

Young people, who tend to be healthy, idealistic, and motivated, are an excellent pool of potential voluntary unpaid blood donors. Recruiting and retaining young blood donors improves the long term safety and sufficiency of a country's blood supply. Knowledge, attitude, and beliefs about Human immunodeficiency virus (HIV) should play an important role in prevention of disease transmission. This study was a questionnaire based survey, conducted to explore the levels of knowledge, attitude, and beliefs about HIV in young college student blood donors. The results showed that the proportion of participants with comprehensive knowledge of HIV prevention and transmission was lesser than expected. Increase in education level and male gender was found to be significantly associated with high HIV-related knowledge. The responses on the different aspects of HIV-related attitude were also varied and there is still stigma associated with Acquired Immunodeficiency Syndrome (AIDS) even in the educated groups. There was a spectrum of myths and misperceptions emphasizing the need of education that recognizes the social context of attitude towards HIV. Results from this study may contribute to the development of appropriate educational and training material for this group of donors which in turn, may assist in achieving the elusive goal of safe blood supply in future.

Recurrent or prolonged severe infections associated to panleukopenia strongly suggest primary immune disorders. In recent years, new immunodeficiency syndromes turned up: besides the importance of continuous clinical characterization throughout added reports, the phenotype can easily lead to diagnosis of known rare entities. Our purpose is to review main emerging genetic syndromes featuring lymphopenia combined to neutropenia and/or monocytopenia in order to facilitate diagnosis of rare primary immune deficiencies.

Human lipodystrophies represent a heterogeneous group of diseases characterized by generalized or partial fat loss, with fat hypertrophy in other depots when partial. Insulin resistance, dyslipidemia and diabetes are generally associated, leading to early complications. Genetic forms are uncommon: recessive generalized congenital lipodystrophies result in most cases from mutations in the genes encoding seipin or the 1-acyl-glycerol-3-phosphate-acyltransferase 2 (AGPAT2). Dominant partial familial lipodystrophies result from mutations in genes encoding the nuclear protein lamin A/C or the adipose transcription factor PPARγ. Importantly, lamin A/C mutations are also responsible for metabolic laminopathies, resembling the metabolic syndrome and progeria, a syndrome of premature aging. A number of lipodystrophic patients remain undiagnosed at the genetic level. Acquired lipodystrophy can be generalized, resembling congenital forms, or partial, as the Barraquer-Simons syndrome, with loss of fat in the upper part of the body contrasting with accumulation in the lower part. Although their aetiology is generally unknown, they could be associated with signs of auto-immunity. The most common forms of lipodystrophies are iatrogenic. In human immunodeficiency virus-infected patients, some first generation antiretroviral drugs were strongly related with peripheral lipoatrophy and metabolic alterations. Partial lipodystrophy also characterize patients with endogenous or exogenous long-term corticoid excess. Treatment of fat redistribution can sometimes benefit from plastic surgery. Lipid and glucose alterations are difficult to control leading to early occurrence of diabetic, cardio-vascular and hepatic complications. PMID:20551664

Severe Epstein-Barr virus infection in primary immunodeficiency and the normal host.

Epstein-Barr virus (EBV) infection is ubiquitous in humans, but the majority of infections have an asymptomatic or self-limiting clinical course. Rarely, individuals may develop a pathological EBV infection with a variety of life threatening complications (including haemophagocytosis and malignancy) and others develop asymptomatic chronic EBV viraemia. Although an impaired ability to control EBV infection has long been recognised as a hallmark of severe T-cell immunodeficiency, the advent of next generation sequencing has identified a series of Primary Immunodeficiencies in which EBV-related pathology is the dominant feature. Chronic active EBV infection is defined as chronic EBV viraemia associated with systemic lymphoproliferative disease, in the absence of immunodeficiency. Descriptions of larger cohorts of patients with chronic active EBV in recent years have significantly advanced our understanding of this clinical syndrome. In this review we summarise the current understanding of the pathophysiology and natural history of these diseases and clinical syndromes, and discuss approaches to the investigation and treatment of severe or atypical EBV infection. © 2016 John Wiley & Sons Ltd.

Recently a newly identified clinical syndrome of disseminated non-tuberculous mycobacterial diseases (with or without other opportunistic infections in adult patients who were previously healthy, has been recognized in association with an acquired autoantibody to interferon-gamma. This syndrome is emerging as an important cause of morbidity and mortality, especially among people of Asian descent. Trigger for the production of this autoantibody remains unknown, but genetic factors are strongly suspected to be involved. We compared HLA genotyping between 32 patients with this clinical syndrome, and 38 controls. We found that this clinical syndrome was associated with very limited allele polymorphism, with HLA-DRB1 and DQB1 alleles, especially HLA-DRB1*15:01, DRB1*16:02, DQB1*05:01 and DQB1*05:02. Odds ratio of DRB1*15:01, DRB1*16:02, DQB1*05:01 and DQB1*05:02 were 7.03 (95% CI, 2.18–22.69, P<0.0001, 9.06 (95% CI, 2.79–29.46, P<0.0001), 6.68 (95% CI, 2.29–19.52, P = 0.0004), and 6.64 (95% CI, 2.30–19.20, P = 0.0004), respectively.

The Human Immunodeficiency Virus (HIV) and infections related to it can affect multiple sites in the hearing system. The use of High-Activity Anti-Retroviral Therapy (HAART) can cause side effects such as ototoxicity. Thus, no consistent patterns of hearing impairment in adults with Human Immunodeficiency Virus / Acquired Immune Deficiency Syndrome have been established, and the problems that affect the hearing system of this population warrant further research. This study aimed to compare the audiological and electrophysiological data of Human Immunodeficiency Virus-positive patients with and without Acquired Immune Deficiency Syndrome, who were receiving High-Activity Anti-Retroviral Therapy, to healthy individuals. It was a cross-sectional study conducted with 71 subjects (30-48 years old), divided into groups: Research Group I: 16 Human Immunodeficiency Virus-positive individuals without Acquired Immunodeficiency Syndrome (not receiving antiretroviral treatment); Research Group II: 25 Human Immunodeficiency Virus-positive individuals with Acquired Immunodeficiency Syndrome (receiving antiretroviral treatment); Control Group: 30 healthy subjects. All individuals were tested by pure-tone air conduction thresholds at 0.25-8kHz, extended high frequencies at 9-20kHz, electrophysiological tests (Auditory Brainstem Response - ABR, Middle Latency Responses - MLR, Cognitive Potential - P300). Research Group I and Research Group II had higher hearing thresholds in both conventional and high frequency audiometry when compared to the control group, prolonged latency of waves I, III, V and interpeak I-V in Auditory Brainstem Response and prolonged latency of P300 Cognitive Potential. Regarding Middle Latency Responses, there was a decrease in the amplitude of the Pa wave of Research Group II compared to the Research Group I. Both groups with Human Immunodeficiency Virus had higher hearing thresholds when compared to healthy individuals (group exposed to antiretroviral

Zoonotic events of simian immunodeficiency virus (SIV) from non-human primates to humans have generated the acquired immunodeficiency syndrome (AIDS), one of the most devastating infectious disease of the last century with more than 30 million people dead and about 40.3 million people currently infected worldwide. Human immunodeficiency virus (HIV-1 and HIV-2), the two major viruses that cause AIDS in humans are retroviruses of the lentivirus genus. The genus includes arthritis-encephalitis virus (CAEV) and Maedi-Visna virus (MVV), and a heterogeneous group of viruses known as small ruminant lentiviruses (SRLVs), affecting goat and sheep. Lentivirus genome integrates into the host DNA, causing persistent infection associated with a remarkable diversity during viral replication. Direct evidence of mixed infections with these two closely related SRLVs was found in both sheep and goats. The evidence of a genetic continuum with caprine and ovine field isolates demonstrates the absence of an efficient species barrier preventing cross-species transmission. In dual-infected animals, persistent infections with both CAEV and MVV have been described, and viral chimeras have been detected. This not only complicates animal trade between countries but favors the risk that highly pathogenic variants may emerge as has already been observed in the past in Iceland and, more recently, in outbreaks with virulent strains in Spain. SRLVs affecting wildlife have already been identified, demonstrating the existence of emergent viruses adapted to new hosts. Viruses adapted to wildlife ruminants may acquire novel biopathological properties which may endanger not only the new host species but also domestic ruminants and humans. SRLVs infecting sheep and goats follow a genomic evolution similar to that observed in HIV or in other lentiviruses.

We explored the possibility that neurologic and neuropsychological changes constitute the earliest detectable manifestations of human immunodeficiency virus (HIV) infection. Without knowledge of HIV status, we assessed neurologic signs and symptoms and administered a battery of neuropsychological tests to 208 homosexual men, of whom 84 were HIV negative, 49 were HIV positive and asymptomatic, 29 were mildly symptomatic, and 46 had significant medical symptoms but not the acquired immunodeficiency syndrome. There was no difference between the HIV-negative and HIV-positive men in the frequency of neurologic signs or of defective or borderline performance on any neuropsychological test. However, HIV-positive men performed slightly but significantly worse than HIV-negative men on tests of verbal memory, executive function, and language. Similar results were obtained when comparisons were limited to HIV-positive medically asymptomatic and HIV-negative men. There was no degradation of neurologic status or neuropsychological performance across stages of HIV severity, but neurologic and neuropsychological summary scores correlated with CD4/CD8 ratios in the HIV-positive group. Ratings of neurologic signs and symptoms correlated with neuropsychological summary scores in the HIV-positive group only. Cognitive complaints were more frequent in the HIV-positive men; they correlated with actual test performance in the HIV-positive but not HIV-negative men. The constellation of subjective and objective neuropsychological and neurologic findings suggests the possibility of a definable syndrome associated with HIV infection in asymptomatic individuals.

Involvement of the central nervous system (CNS) by Histoplasma capsulatum in AIDS is uncommon and not easily recognized. CNS histoplasmosis cases from our institution were identified by a retrospective chart review from 2004-2014. A thorough literature search was performed for additional cases and their characteristics were compared. Clinical findings, treatment and outcomes are discussed. A total of 5 cases from our institution were identified. They had a clinical presentation that included classic signs of meningitis, often with evidence of disseminated involvement, and was typically severe with important neurological impairment. These cases were treated with antifungal agents, including a lipid amphotericin B formulation and azole drugs, but eventually 3 experienced nonresolution of their disease likely because of lack of adherence to therapy and died from their infection. The clinical presentation, treatment and outcome of these cases did not significantly differ from cases found in the review of the literature. Clinicians practicing in endemic areas should be aware of this rare but serious form of histoplasmosis. The recognition of 5 cases of CNS histoplasmosis in AIDS patients from a single institution suggests that histoplasmosis should be included in the differential diagnosis of the CNS complications of AIDS.

[Acquired immunodeficiency syndrome by vertical transmission: neurological disorders].

PubMed

Tellechea-Rotta, N; Legido, A

Forty million people are currently infected by HIV; of these, 50% are women and children. Vertical transmission occurs in 90% of the cases reported in the literature and was also observed by the authors of the present study at Hospital de Clínicas de Porto Alegre, Brazil, in the follow up of 340 HIV positive children since 1985. Transmission can occur during pregnancy (intrauterine) or during labor and delivery (intrapartum). In addition, HIV has been identified in the breast milk of infected mothers, which represents a contraindication for breastfeeding in these cases. Laboratory diagnosis is carried out using the following tests: ELISA, Western blot, and indirect immunofluorescence. Neurological manifestations in children may be divided into primary neurological diseases and secondary complications. Primary neurological diseases include both static encephalopathy, of slow evolution, and progressive encephalopathy, which affects neuropsychomotor development. The follow up of 340 children with AIDS showed encephalopathy in 32.5% of cases and delayed neuropsychomotor development in 42.5%. Opportunistic infections occurred in 33.8% of cases (one infant presented meningoencephalitis caused by Trypanosoma cruzi). One child presented lymphomas, 2.6% had cerebrovascular accidents, and 5% had peripheral neuropathies. Currently, 54 children of those followed since birth have over 10 years of age, and of these, 31 (57%) present neurological symptoms 40% with encephalopathy and 30% with neurological complications; the remaining children present educational, behavioral, and developmental difficulties. Several factors have influenced the natural history of AIDS in childhood, such as early diagnosis, drug regimen used, social, economic, and nutritional conditions, as well as health practices aimed at this population.

A pilot project, ¿Youth Inform¿ endorsed by the Ministry of Health and Ministry of Education, Singapore, was undertaken in 1992 for 2 years. It aims to enhance sexually transmitted disease (STDs)/human immunodeficiency virus (HIV) control in Singapore by providing structured information for young people between the ages of 16 to 20 years in Polytechnics, Junior Colleges, Centralised Institutes and Pre-University Centres. Project Youth Inform comprises 8 components. They include a focus group discussion, a training seminar for teachers, a lecture/slide presentation cum question-and-answer session, an educational booklet/bookmark, exhibitions, a video, provisions for anonymous questions, and an evaluation. The programme is conducted during school hours at the premises of the institutions and the attendance per session is between 150 to 350 students. A total of 152 sessions have been completed for all the schools. It is ongoing and is currently administered by the School Health Service and Training and Health Education Department. Feedback from principals, teachers and students was gathered formally through surveys and informally through interviews and observations. One thousand students were randomly selected for the survey to assess their responses towards the programme. Eighty-six percent reported that they found it educational and informative. Indicators found to have an influence on the effectiveness of the programme were timing, vocabulary used (medical terms) and integration of the programme into the school's curriculum. In conclusion, Project Youth Inform was on the whole positively received. However, it is essential to constantly accommodate and adapt to new facts and methods of teaching and maintain close coordination with the Ministries and the schools. An effective STD/acquired immune deficiency syndrome programme is an important step towards the prevention, management and control of the epidemic.

To evaluate relationships between retinal vessel caliber, AIDS-related factors, and mortality. Longitudinal, observational cohort study. We evaluated data for participants without ocular opportunistic infections at initial examination (baseline) in the Longitudinal Studies of the Ocular Complications of AIDS (1998-2008). Semi-automated evaluation of fundus photographs (1 eye/participant) determined central retinal artery equivalent (CRAE), central retinal vein equivalent (CRVE), and arteriole-to-venule ratio (AVR) at baseline. Multiple linear regression models, using forward selection, identified independent relationships between indices and various host- and disease-related variables. Included were 1250 participants. Mean follow-up for determination of mortality was 6.1 years. Smaller CRAE was related to increased age (P < .001) and hypertension (P < .001); larger CRAE was related to lower hematocrit (P = .002). Larger CRAE and CRVE were associated with black race (P < .001). Larger CRVE was related to smoking (P = .004); smaller CRVE was related to age (P < .001) and higher mean corpuscular volume (P = .001). We observed the following relationships with AIDS-associated factors: smaller CRAE and larger CRVE with history of highly active antiretroviral therapy (HAART; P < .001); and larger CRAE with lower CD4+ T lymphocyte count (P = .04). We did not identify independent relationships with human immunodeficiency virus RNA blood levels. There was a 12% (95% CI, 2%-21%) increase in mortality risk per quartile of decreasing AVR (P = .02). Variations in retinal vascular caliber are associated with AIDS-specific factors and are markers for increased mortality risk. Relationships are consistent with the hypothesis that the vasculature is altered by known atherogenic effects of chronic HAART or the prolonged inflammatory state associated with AIDS.

2012-01-01

The purpose of this study was to evaluate the methodological quality of quantitative lesbian, gay, bisexual, and transgender nursing research from 2000 to 2010. Using a key word search in Cumulative Index to Nursing and Allied Health Literature, 188 studies were identified and 40 met the criteria, which included descriptive, experimental, quasi-experimental, or observational (case control, cohort, and cross-sectional) design. The methodological quality of these studies was similar to that reported for medical and nursing educational research. The foci of these lesbian, gay, bisexual, and transgender studies were biased toward human immunodeficiency virus, acquired immunodeficiency syndrome, and sexually transmitted diseases, and 58.5% of the funded research was related to human immunodeficiency virus or acquired immunodeficiency syndrome. To provide evidence-based health care to these populations, an understanding of the current state of research is crucial.

Reported herein is the first case of Leishmania–human immunodeficiency virus (HIV) coinfection in Ecuador. In Ecuador, HIV infections overlap endemic areas of leishmaniasis. Immunosuppression is a well-established risk factor for developing severe disease. This is a severe case of a 32-year-old man presenting with disseminated pleomorphic ulcers, papules, and cutaneous plaque-like lesions over his whole body. Numerous amastigotes were observed in both skin scrapings and biopsies. The sequence of the cytochrome b gene confirmed the presence of Leishmania guyanensis. The patient was treated but failed to respond to meglumine antimoniate and amphotericin B. Six months later, the patient died due to bacterial septic shock. PMID:28193741

The interplay between viral and host proteins has been well studied to elucidate virus-host interactions and their relevance to virulence. Mammalian genes encode apolipoprotein B mRNA-editing enzyme catalytic polypeptide-like 3 (APOBEC3) proteins, which act as intrinsic restriction factors against lentiviruses. To overcome APOBEC3-mediated antiviral actions, lentiviruses have evolutionarily acquired an accessory protein, viral infectivity factor (Vif), and Vif degrades host APOBEC3 proteins via a ubiquitin/proteasome-dependent pathway. Although the Vif-APOBEC3 interaction and its evolutionary significance, particularly those of primate lentiviruses (including HIV) and primates (including humans), have been well investigated, those of nonprimate lentiviruses and nonprimates are poorly understood. Moreover, the factors that determine lentiviral pathogenicity remain unclear. Here, we focus on feline immunodeficiency virus (FIV), a pathogenic lentivirus in domestic cats, and the interaction between FIV Vif and feline APOBEC3 in terms of viral virulence and evolution. We reveal the significantly reduced diversity of FIV subtype B compared to that of other subtypes, which may associate with the low pathogenicity of this subtype. We also demonstrate that FIV subtype B Vif is less active with regard to feline APOBEC3 degradation. More intriguingly, we further reveal that FIV protease cleaves feline APOBEC3 in released virions. Taken together, our findings provide evidence that a lentivirus encodes two types of anti-APOBEC3 factors, Vif and viral protease. IMPORTANCE During the history of mammalian evolution, mammals coevolved with retroviruses, including lentiviruses. All pathogenic lentiviruses, excluding equine infectious anemia virus, have acquired the vif gene via evolution to combat APOBEC3 proteins, which are intrinsic restriction factors against exogenous lentiviruses. Here we demonstrate that FIV, a pathogenic lentivirus in domestic cats, antagonizes feline APOBEC3

Human immunodeficiency virus (HIV) and hepatitis C virus (HCV) share the same transmission routes; therefore, coinfection is frequent. An estimated 5-10 million individuals alone in the western world are infected with both viruses. The majority of people acquire HCV by injection drug use and, to a lesser extent, through blood transfusion and blood products. Recently, there has been an increase in HCV infections among men who have sex with men. In the context of effective antiretroviral treatment, liver-related deaths are now more common than Acquired Immune Deficiency Syndrome-related deaths among HIV-HCV coinfected individuals. Morbidity and mortality rates from chronic HCV infection will increase because the infection incidence peaked in the mid-1980s and because liver disease progresses slowly and is clinically silent to cirrhosis and end-stage-liver disease over a 15-20 year time period for 15%-20% of chronically infected individuals. HCV treatment has rapidly changed with the development of new direct-acting antiviral agents; therefore, cure rates have greatly improved because the new treatment regimens target different parts of the HCV life cycle. In this review, we focus on the epidemiology, diagnosis and the natural course of HCV as well as current and future strategies for HCV therapy in the context of HIV-HCV coinfection in the western world.

To report the experience of a tertiary care hospital with allogeneic hematopoietic stem cell transplantation in children with primary immunodeficiencies. Seven pediatric patients with primary immunodeficiencies (severe combined immunodeficiency: n = 2; combined immunodeficiency: n = 1; chronic granulomatous disease: n = 1; hyper-IgM syndrome: n = 2; and IPEX syndrome: n = 1) who underwent eight hematopoietic stem cell transplants in a single center, from 2007 to 2010, were studied. Two patients received transplants from HLA-identical siblings; the other six transplants were done with unrelated donors (bone marrow: n = 1; cord blood: n = 5). All patients had pre-existing infections before hematopoietic stem cell transplants. One patient received only anti-thymocyte globulin prior to transplant, three transplants were done with reduced intensity conditioning regimens and four transplants were done after myeloablative therapy. Two patients were not evaluated for engraftment due to early death. Three patients engrafted, two had primary graft failure and one received a second transplant with posterior engraftment. Two patients died of regimen related toxicity (hepatic sinusoidal obstruction syndrome); one patient died of progressive respiratory failure due to Parainfluenza infection present prior to transplant. Four patients are alive and well from 60 days to 14 months after transplant. Patients' status prior to transplant is the most important risk factor on the outcome of hematopoietic stem cell transplants in the treatment of these diseases. Early diagnosis and the possibility of a faster referral of these patients for treatment in reference centers may substantially improve their survival and quality of life.

Acquired perforating dermatosis in a patient with Poland syndrome.

Fistarol, Susanna K; Itin, Peter H

2003-01-01

Acquired perforating dermatosis (APD) is characterized by umbilicated 1- to 10-mm-measuring papulonodules with a central adherent oystershell-like keratotic plug, typically on the dorsa of the hands, forearms and over the knees. APD is associated with systemic diseases, especially diabetes mellitus and/or renal failure. Histologically the lesions show transepidermal elimination of altered dermal components into a cup-shaped epidermal depression. We present a 69-year-old man with coexisting APD and Poland syndrome (PS), an association not yet described. PS (OMIM 173800) is a rare congenital anomaly consisting of unilateral partial or total absence of the greater pectoralis muscle and ipsilateral symbrachydactyly. Most cases of PS are sporadic as it was in our case. Our patient had, in addition, an untreated diabetic condition, hyperuricaemia, dilated cardiomyopathy and a very recent pulmonary embolism. He responded to therapy with allopurinol. Copyright 2003 S. Karger AG, Basel

The puzzling role of CXCR4 in human immunodeficiency virus infection.

Vicenzi, Elisa; Liò, Pietro; Poli, Guido

2013-01-01

The human immunodeficiency virus type-1 (HIV-1) is the etiological agent of the acquired immunodeficiency syndrome (AIDS), a disease highly lethal in the absence of combination antiretroviral therapy. HIV infects CD4(+) cells of the immune system (T cells, monocyte-macrophages and dendritic cells) via interaction with a universal primary receptor, the CD4 molecule, followed by a mandatory interaction with a second receptor (co-receptor) belonging to the chemokine receptor family. Apart from some rare cases, two chemokine receptors have been evolutionarily selected to accomplish this need for HIV-1: CCR5 and CXCR4. Yet, usage of these two receptors appears to be neither casual nor simply explained by their levels of cell surface expression. While CCR5 use is the universal rule at the start of every infection regardless of the transmission route (blood-related, sexual or mother to child), CXCR4 utilization emerges later in disease coinciding with the immunological deficient phase of infection. Moreover, in most instances CXCR4 use as viral entry co-receptor is associated with maintenance of CCR5 use. Since antiviral agents preventing CCR5 utilization by the virus are already in use, while others targeting either CCR5 or CXCR4 (or both) are under investigation, understanding the biological correlates of this "asymmetrical" utilization of HIV entry co-receptors bears relevance for the clinical choice of which therapeutics should be administered to infected individuals. We will here summarize the basic knowledge and the hypotheses underlying the puzzling and yet unequivocal role of CXCR4 in HIV-1 infection.

Epstein–Barr Virus Susceptibility in Activated PI3Kδ Syndrome (APDS) Immunodeficiency

PubMed Central

Carpier, Jean-Marie; Lucas, Carrie L.

2018-01-01

Activated PI3Kδ Syndrome (APDS) is an inherited immune disorder caused by heterozygous, gain-of-function mutations in the genes encoding the phosphoinositide 3-kinase delta (PI3Kδ) subunits p110δ or p85δ. This recently described primary immunodeficiency disease (PID) is characterized by recurrent sinopulmonary infections, lymphoproliferation, and susceptibility to herpesviruses, with Epstein–Barr virus (EBV) infection being most notable. A broad range of PIDs having disparate, molecularly defined genetic etiology can cause susceptibility to EBV, lymphoproliferative disease, and lymphoma. Historically, PID patients with loss-of-function mutations causing defective cell-mediated cytotoxicity or antigen receptor signaling were found to be highly susceptible to pathological EBV infection. By contrast, the gain of function in PI3K signaling observed in APDS patients paradoxically renders these patients susceptible to EBV, though the underlying mechanisms are incompletely understood. At a cellular level, APDS patients exhibit deranged B lymphocyte development and defects in class switch recombination, which generally lead to defective immunoglobulin production. Moreover, APDS patients also demonstrate an abnormal skewing of T cells toward terminal effectors with short telomeres and senescence markers. Here, we review APDS with a particular focus on how the altered lymphocyte biology in these patients may confer EBV susceptibility. PMID:29387064

Tuberculosis of the prostate is rare and is thought to be either due to haematogenous dissemination or secondary to renal infection. We describe, possibly for the first time, two male patients with the acquired immunodeficiency syndrome who had tuberculous abscesses in the prostate discovered at post-mortem examination. Only one of them had mild urinary symptoms and neither had evidence of urogenital tuberculosis before death. We suggest that in a patient with acquired immunodeficiency syndrome tuberculous infection of the prostate should be sought by microscopic examination of the urine, semen and prostatic fluid obtained after massage.

Current laboratory diagnosis of opportunistic enteric parasites in human immunodeficiency virus-infected patients

PubMed Central

De, Anuradha

2013-01-01

Diarrhea is a major cause of morbidity and mortality in human immunodeficiency virus (HIV)-infected individuals. Opportunistic enteric parasitic infections are encountered in 30-60% of HIV seropositive patients in developed countries and in 90% of patients in developing countries. Once the CD4+ cell count drops below 200 cells/μl, patients are considered to have developed acquired immunodeficiency syndrome (AIDS), with the risk of an AIDS-defining illness or opportunistic infection significantly increasing. Opportunistic enteric parasites encountered in these patients are Cryptosporidium, Isospora, Cyclospora, and microsporidia; as well as those more commonly associated with gastrointestinal disease, for example, Giardia intestinalis, Entamoeba histolytica, Strongyloides stercoralis, and also rarely Balantidium coli. In view of AIDS explosion in India, opportunistic enteric parasites are becoming increasingly important and it has to be identified properly. Apart from wet mounts, concentration methods for stool samples and special staining techniques for identification of these parasites, commercially available fecal immunoassays are widely available for the majority of enteric protozoa. Molecular methods such as polymerase chain reaction (PCR), PCR-restriction fragment length polymorphism, flow cytometry, and sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE), have also come in the pipeline for early diagnosis of these infections. Proper disposal of the feces to prevent contamination of the soil and water, boiling/filtering drinking water along with improved personal hygiene might go a long way in preventing these enteric parasitic infections.

Dogma disputed: potential endemic heterosexual transmission of human immunodeficiency virus in Australia.

PubMed

Chapman, S

1992-06-01

The concept of tertiary sexual transmission of human immunodeficiency virus (HIV) has been central to government efforts to communicate notions of risk to heterosexuals in Australia. Data on heterosexually transmitted acquired immune deficiency syndrome (AIDS) and HIV for Australia are reviewed with emphasis given to the probability of misclassification bias in the heterosexually acquired and 'other/undetermined' categories. Tertiary cases are almost certainly rare in Australia, with little evidence of any increase in their incidence since the first cases were recorded. Three factors (low probability of exposure, the infectivity of HIV and a comparatively low rate of sexual partner change) make it improbable that Australian heterosexuals with no risk factors will experience endemic HIV infection, with a caveat to this conclusion lying in the potential of Australian sex tourism to Southeast Asia for introducing HIV into the Australian heterosexual population. Four hegemonic factors which have acted to suppress any serious debate of the notion that HIV in Australia is unlikely to become endemic among heterosexuals are discussed: the political 'democratization' of risk inspired by concerns that gay men should not be further vilified as a victim group; the preventive imperative; a reluctance among health educators to question the very foundations of the message they are employed to deliver; and a reluctance to curtail 'Trojan horse' benefits to sexually transmissible disease prevention engendered by HIV education promoting safe sex messages.

A constant threat for HIV: Fc-engineering to enhance broadly neutralizing antibody activity for immunotherapy of the acquired immunodeficiency syndrome.

PubMed

Nimmerjahn, Falk

2015-08-01

Passive immunotherapy with polyclonal or hyperimmune serum immunoglobulin G (IgG) preparations provides an efficient means of protecting immunocompromised patients from microbial infections. More recently, the use of passive immunotherapy to prevent or to treat established infections with the human immunodeficiency virus (HIV) has gained much attention, due to promising preclinical data obtained in monkey and humanized mouse in vivo model systems, demonstrating that the transfer of HIV-specific antibodies can not only prevent HIV infection, but also diminish virus load during chronic infection. Furthermore, an array of broadly neutralizing HIV-specific antibodies has become available and the importance of the IgG constant region as a critical modulator of broadly neutralizing activity has been demonstrated. The aim of this review is to summarize the most recent findings with regard to the molecular and cellular mechanisms responsible for antibody-mediated clearance of HIV infection, and to discuss how this may help to improve HIV therapy via optimizing Fcγ-receptor-dependent activities of HIV-specific antibodies. © 2015 WILEY-VCH Verlag GmbH & Co.

Hematopoietic stem cell transplantation (HSCT) is the definitive therapy for a variety of primary immunodeficiency syndromes (PIDs). However, no more than 30% of the patients will have a human leukocyte antigen (HLA)-identical sibling. We retrospectively analyzed our results of ten patients with PID; severe combined immunodeficiency (SCID) (n = 7), hyper IgM (HIgM) (n = 1) and combined immunodeficiency (CID) (n = 2), who lacked a fully matched donor and underwent mismatched related HSCT during the period from 2008 to 2010. The median age at the time of transplantation ranged between 3 and 84 months (median 6.5 months). Peripheral blood stem cells (PBSC) were used in all HSCTs. The mean value of the peripheral CD34+ cells infused was 9.19 × 10 (6) /kg recipient weight. Patients received different conditioning protocols. All patients received anti graft versus host disease (GVHD) prophylaxis and all were engrafted. Mixed chimerism (5-55%) was noticed. GVHD was observed in 50% of the patients. Post-transplant follow-up ranged from 3 weeks to 36 months (median 15 months). Five patients are still alive while one patient developed engraftment syndrome followed by graft slippage for which a second transplant with CD34+ stem cells 5.8 × 10 (6) /kg recipient's weight was infused. The others died from sepsis and transplant-related complications. Immune reconstitution was noticed in four patients. In conclusion, HLA-haploidentical stem cell transplantation may be feasible, with appropriate GVHD prophylaxis, for patients with PID who lack a fully matched donor.

Verrucous skin lesions have been attributed to various herpes viruses in immunosuppressed patients, including those with human immunodeficiency virus infection (HIV). We examined such lesions from six HIV-infected patients to determine the range of microscopic findings present and to establish which herpesviruses were present. Verrucous epidermal hyperplasia, pseudocarcinomatous hyperplasia, and massive hyperkeratosis correlate with the warty clinical appearance of the lesions. Herpetic cytopathic changes, including multinucleated epidermal giant cells, steel-gray nuclei, necrotic acantholytic keratinocytes, and Cowdry type A nuclear inclusions were seen most prominently in the dells between papillations and in adnexal epithelium. In two cases, increased numbers of spindled cells were seen in the dermis. Immunoperoxidase staining with anti-type IV collagen antibodies demonstrated that these findings were not those of Kaposi's sarcoma, but represent a fibrotic reaction to the infection. Viral cultures of four of the cases demonstrated the presence of varicella-zoster virus, whose presence was detected by the polymerase chain reaction in paraffin-embedded lesional tissue from all six cases. Polymerase chain reaction did not show the presence of cytomegalovirus, herpes simplex, Epstein-Barr, or human papillomavirus. We conclude that these unusual verrucous lesions are a chronic manifestation of herpes zoster infection and that the reported presence of other agents in such lesions is probably coincidental.

Good syndrome (GS) is defined as the association between thymoma and immune deficiency. It is often complicated by broncho-pulmonary bacterial infections and rhinosinusitis. This disease accounts for only 5% of all parathymic syndromes. These recurrent respiratory infections can cause bronchiectasis associated with Good syndrome. We report the case of a 52-year old woman hospitalized for non resolutive infectious pneumonitis. Chest CT scan showed bronchiectasis associated with thymoma confirmed by biopsy. The discovery of hypogammaglobulinemia allowed the diagnosis of Good syndrome.

Feline immunodeficiency virus (FIV), the causative agent of an acquired immunodeficiency syndrome in cats (feline AIDS), is a ubiquitous health threat to the domestic and feral cat population, also triggering disease in wild animals. No registered antiviral compounds are currently available to treat FIV-infected cats. Several human antiviral drugs have been used experimentally in cats, but not without the development of serious adverse effects. Here we report on the treatment of six naturally FIV-infected cats, suffering from moderate to severe disease, with the antiretroviral compound (R)-9-(2-phosphonylmethoxypropyl)-2,6-diaminopurine ([R]-PMPDAP), a close analogue of tenofovir, a widely prescribed anti-HIV drug in human medicine. An improvement in the average Karnofsky score (pretreatment 33.2 ± 9.4%, post-treatment 65±12.3%), some laboratory parameters (ie, serum amyloid A and gammaglobulins) and a decrease of FIV viral load in plasma were noted in most cats. The role of concurrent medication in ameliorating the Karnofsky score, as well as the possible development of haematological side effects, are discussed. Side effects, when noted, appeared mild and reversible upon cessation of treatment. Although strong conclusions cannot be drawn owing to the small number of patients and lack of a placebo-treated control group, the activity of (R)-PMPDAP, as observed here, warrants further investigation. © ISFM and AAFP 2014.

The aims of the study were to determine the knowledge of HIV/AIDS among college girl students, to expose the college girl students to targeted HIV/AIDS education and to assess the impact of HIV/ AIDS health education on college girl students. A cross-sectional study was designed over the period September 2009 to February 2010. Study participants included 139 students of BLDEA's Arts and Commerce College for Women, Bijapur, Karnataka. Results indicated knowledge regarding HIV/ AIDS improved substantially, especially, with relation to various modes of transmission viz unsterilised syringes (41% to 72%), pregnant mother to child (23% to 66%) blood transfusion (20% to71%) and regarding preventive measures namely adherence to single partner (68% to 95%), use of condom (18% to 68%/), use of tested blood for transfusion (21% to 55%). The study showed significant difference between pre and post-test knowledge regarding HIV/AIDS

Light chain proximal tubulopathy is a rarely reported entity associated with plasma cell dyscrasia that classically manifests as acquired Fanconi syndrome and is characterized by the presence of κ-restricted crystals in the proximal tubular cytoplasm. We herein present a case of multiple myeloma with Fanconi syndrome and acute kidney injury due to light chain proximal tubulopathy with light chain cast nephropathy. Prominent phagolysosomes and numerous irregularly shaped inclusions with a fibrillary matrix in the cytoplasm of the proximal tubules were identified on electron microscopy. A monotypic light chain of the λ type was detected in the distal tubular casts, proximal tubular cytoplasmic lysosomes and fibrillary inclusions on immunofluorescence and immune electron microscopy. This case underscores the importance of conducting careful ultrastructural investigations and immunocytologic examinations of light chains for detecting and diagnosing light chain proximal tubulopathy.

Clinical training in human immunodeficiency virus disease for community physicians. The Los Angeles experience.

PubMed Central

Katsufrakis, P. J.; Radecki, S. E.

1992-01-01

In the past decade, the increased number of persons being treated for infection with the human immunodeficiency virus (HIV) has placed an enormous burden on specialty clinics. This is especially true in Los Angeles, where care of patients with the acquired immunodeficiency syndrome (AIDS) has been termed a "crisis" situation. Especially in its early stages, HIV disease can be appropriately managed by primary care physicians who provide patients with medical and psychological counseling and refer them to specialists when major AIDS-related complications develop. Physicians completing their training as recently as 5 years ago, however, received little systematic preparation in the care of HIV-infected patients and thus may lack important skills such as the ability to recognize opportunistic infections early in their course. By means of a 1-week intensive preceptorship in a high-volume AIDS clinic, we are preparing community physicians to assume a more active role in providing care for this growing patient population. In the preceptorship, participants receive one-on-one training from specialists in infectious diseases, pulmonary diseases, and hematology and oncology, as well as from internists and family physicians. Evaluation of the clinical experience demonstrated a greater level of confidence on the part of program participants in treating HIV-infected patients and showed that participants screen and test high-risk patients in their practices and devote a substantial proportion of their practices to caring for HIV-infected patients.

This study evaluates the efficiency of rural health centers in Rwanda in delivering the three key human immunodeficiency virus/acquired immunodeficiency syndrome services: antiretroviral treatment, prevention of mother-to-child transmission, and voluntary counseling and testing using data envelopment analysis, and assesses the impact of community-based health insurance (CBHI) and performance-based financing on improving the delivery of the three services. Results show that health centers average efficiency of 78%, and despite the observed variation, the performance increased by 15.6% from 2006 through 2007. When the services are examined separately, each 1% growth of CBHI use was associated with 3.7% more prevention of mother-to-child transmission and 2.5% more voluntary counseling and testing services. Although more health centers would have been needed to evaluate performance-based financing, we found that high use of CBHI in Rwanda was an important contributor to improving human immunodeficiency virus/acquired immunodeficiency syndrome services in rural health centers in Rwanda.

Fat embolism is a known complication of severe trauma and closed chest cardiac resuscitation both of which are more common in the lung transplant donor population and can lead to donor-acquired fat embolism syndrome (DAFES). The objective was to review the diagnosis and management of DAFES in the lung transplantation literature and at our centre. We performed a literature review on DAFES using the Medline database. We then reviewed the transplant record of Brigham and Women's Hospital, a large academic hospital with an active lung transplant programme, for cases of DAFES. We identified 2 cases of DAFES in our centre, one of which required extracorporeal membrane oxygenation (ECMO) for successful management. In contrast to the broader literature on DAFES, which emphasizes unsuccessfully treated cases, both patients survived. DAFES is a rare but likely underappreciated early complication of lung transplant as it can mimic primary graft dysfunction. Aggressive interventions, including ECMO, may be necessary to achieve a good clinical outcome following DAFES. © The Author 2015.

Abstract Cyclical thrombocytosis, acquired von Willebrand syndrome, aggressive non-melanoma skin cancers and other hydroxyurea complications have been reported in Philadelphia-negative myeloproliferative neoplasms (MPNs), but their incidence and clinical consequences have not been defined in a large cohort of patients. We conducted a retrospective analysis of 188 consecutive patients with MPNs specifically addressing the incidence of these complications. Cyclical thrombocytosis was documented in 29 patients (15%), the majority of whom were receiving hydroxyurea. Acquired von Willebrand syndrome was identified in 17 of the 84 screened patients (20%), but was not associated with any major bleeding complications. Non-melanoma skin cancers were reported in 51 patients (27%). Hydroxyurea-related fever occurred in nine of 149 patients (6%) who received hydroxyurea. Seventy-three patients (39%) experienced a total of 98 major thrombotic events, with the majority of these occurring prior to or within 3 months of the diagnosis. Cyclical thrombocytosis, acquired von Willebrand syndrome, aggressive non-melanoma skin cancers and other hydroxyurea-related complications are not infrequent in MPNs and have important clinical consequences for management.

Undernourishment and micronutrient deficiencies exacerbate immunosuppression, oxidative stress, acceleration of human immunodeficiency virus (HIV) replication and CD4 T-cell depletion in HIV-infected individuals. The current work reports the serum levels of antioxidant vitamins (vitamins A, C and E) and minerals (Zn, Fe, Cu) in 90 HIV positive subjects attending the Usmanu Danfodiyo University Teaching Hospital (UDUTH), Sokoto, Nigeria. The serum levels of the micronutrients were correlated with the CD4 count of the subjects. The results showed that the HIV positive subjects have significantly lower (P < 0.05) levels of vitamins A, C and E. Also, serum Zn, Fe, Cu and CD4 count were also significantly (P < 0.05) lower compared with the HIV negative subjects. Micronutrient deficiencies were more pronounced in HIV positive subjects with CD4 counts less than 200 cell/μl. The results based on age and sex showed no significant (P > 0.05) difference. Vitamins A, E and C and Zn and Fe showed positive correlation with CD4 count of the HIV positive subjects. The results suggest that the HIV subjects in the study area have lowered serum levels of antioxidant micronutrients and that the levels decrease with increase in the severity of the infection. These may increase the chances of the symptomatic and asymptomatic subjects progressing into full-blown Acquired Immunodeficiency Syndrome.

The fatigue experience for women with human immunodeficiency virus.

Lee, K A; Portillo, C J; Miramontes, H

1999-01-01

To examine fatigue as a symptom experienced by women with human immunodeficiency virus (HIV). A convenience sample of 100 women with HIV. Independent sample t-tests were used to test for mean differences in fatigue related to variables in the women's sociocultural and home environment (ethnicity, employment, marital status, and parenting). Pearson product moment correlations were used to examine significant relationships between fatigue and physiologic variables (age, CD4 cell count, and sleep). Lower CD4 cell counts were related to more daytime sleep, higher evening fatigue, and higher morning fatigue. Morning fatigue was related to duration of wake episodes during the night, napping, and perception of sleep disturbance during the past week. The number of awakenings during the first night predicted the severity of fatigue the next evening. To understand the fatigue experienced by women with HIV, researchers and clinicians must focus on the relative contributions of sociocultural, home, and physiologic environments within which these women live. Additional research is ongoing to identify the strategies these women use to manage daily activities such that gender-relevant and culturally relevant interventions for alleviating fatigue can be tested in women with a variety of chronic illnesses, including HIV and acquired immune deficiency syndrome.

Screening blood donors for human immunodeficiency virus antibody: cost-benefit analysis.

PubMed Central

Eisenstaedt, R S; Getzen, T E

1988-01-01

The costs and benefits of screening blood donors for antibody to human immunodeficiency virus (HIV) are assessed. Total costs, including testing, discarding processed blood, marginal donor recruiting, notifying and evaluating positive donors, are $36,234,000 annually for 10 million donors in 1986. Screening these donors will prevent 292 cases of transfusion-transmitted acquired immune deficiency syndrome (TT-AIDS), saving the costs of therapy and loss of earnings for total benefits of $43,490,480, a benefit:cost ratio of 1.2:1. Net economic benefits of $0.73 per donor will arise from the program. Calculated benefits will rise as increased numbers of infected recipients are diagnosed with longer follow-up or as partially effective therapy increases the cost of caring for patients with AIDS. Changes in test sensitivity, follow-up procedures, estimated value of life, and testing costs will also alter these projections, but none as dramatically as a change in the overall specificity of the screening process. The cost per case of TT-AIDS prevented, $124,089, and cost per year of life extended, $10,885, are comparable to costs of other screening programs. PMID:3126676

Progressive outer retinal necrosis syndrome in the course of systemic lupus erythematosus.

PubMed

Turno-Kręcicka, A; Tomczyk-Socha, M; Zimny, A

2016-12-01

Progressive outer retinal necrosis syndrome (PORN) is a severe clinical variant of necrotizing herpetic chorioretinitis, which occurs almost exclusively in patients with advanced acquired immunodeficiency syndrome (AIDS). To date, only a few cases of PORN have been reported in patients, mostly among those who were immunocompromised. To our knowledge, only one case of PORN in a patient with systemic lupus erythematosus (SLE) has been described. We report the case of a 44-year old HIV-negative patient with lupus nephritis, whom was being treated by mycophenolate mophetil (MMF), arechin and prednisone. After 14 months of MMF therapy, the patient revealed PORN symptoms; and several months later, the patient developed Type B primary central nervous system lymphoma (PCNSL). PORN is usually compared to acute retinal necrosis (ARN) syndrome, because of having the same causative agent: varicella zoster virus (VZV). There are also some similarities in clinical findings. Our observation supports the hypothesis that PORN symptoms in HIV-negative patients can be an intermediate form between ARN and PORN, and can vary according to the patient's immune status. © The Author(s) 2016.

Immune Reconstitution Reactions in Human Immunodeficiency Virus–Negative Patients

Scharschmidt, Tiffany C.; Amerson, Erin H.; Rosenberg, Oren S.; Jacobs, Richard A.; McCalmont, Timothy H.; Shinkai, Kanade

2013-01-01

Background Immune reconstitution inflammatory syndrome (IRIS) is a phenomenon initially described in patients with human immunodeficiency virus. Upon initiation of combination antiretroviral therapy, recovery of cellular immunity triggers inflammation to a preexisting infection or antigen that causes paradoxical worsening of clinical disease. A similar phenomenon can occur in human immunodeficiency virus–negative patients, including pregnant women, neutropenic hosts, solidorgan or stem cell transplant recipients, and patients receiving tumor necrosis factor inhibitors. Observations We report a case of leprosy unmasking and downgrading reaction after stem cell transplantation that highlights some of the challenges inherent to the diagnosis of IRIS, especially in patients without human immunodeficiency virus infection, as well as review the spectrum of previously reported cases of IRIS reactions in this population. Conclusions The mechanism of immune reconstitution reactions is complex and variable, depending on the underlying antigen and the mechanism of immunosuppression or shift in immune status. Use of the term IRIS can aid our recognition of an important phenomenon that occurs in the setting of immunosuppression or shifts in immunity but should not deter us from thinking critically about the distinct processes that underlie this heterogeneous group of conditions.

Crystal Structure of the Full-Length Feline Immunodeficiency Virus Capsid Protein Shows an N-Terminal β-Hairpin in the Absence of N-Terminal Proline

PubMed Central

Folio, Christelle; Sierra, Natalia; Dujardin, Marie; Alvarez, Guzman

2017-01-01

Feline immunodeficiency virus (FIV) is a member of the Retroviridae family. It is the causative agent of an acquired immunodeficiency syndrome (AIDS) in cats and wild felines. Its capsid protein (CA) drives the assembly of the viral particle, which is a critical step in the viral replication cycle. Here, the first atomic structure of full-length FIV CA to 1.67 Å resolution is determined. The crystallized protein exhibits an original tetrameric assembly, composed of dimers which are stabilized by an intermolecular disulfide bridge induced by the crystallogenesis conditions. The FIV CA displays a standard α-helical CA topology with two domains, separated by a linker shorter than other retroviral CAs. The β-hairpin motif at its amino terminal end, which interacts with nucleotides in HIV-1, is unusually long in FIV CA. Interestingly, this functional β-motif is formed in this construct in the absence of the conserved N-terminal proline. The FIV CA exhibits a cis Arg–Pro bond in the CypA-binding loop, which is absent in known structures of lentiviral CAs. This structure represents the first tri-dimensional structure of a functional, full-length FIV CA. PMID:29120364

Hereditary folate malabsorption (HFM) is a rare autosomal recessive disorder. Severe folate deficiency in HFM can result in immunodeficiency. We describe a female infant with HFM who acquired severe Pneumocystis pneumonia. The objective of the present study was to elucidate her immunological phenotype and to examine the time course of immune recovery following parenteral folate therapy. The patient demonstrated a combined immunodeficiency with an impaired T cell proliferation response, pan-hypogammaglobulinemia, and an imbalanced pro-inflammatory cytokine profile. She had normal white blood cell count, normal lymphocyte subsets, and normal complement levels. Two novel mutations were identified within the SLC46A1 gene to produce a compound heterozygote. We confirmed full recovery of her immunological and neurophysiological status with parenteral folate replacement. The time course of recovery of her immunological profile varied widely, however. HFM should be recognized as a unique form of immunodeficiency. Copyright © 2014 Elsevier Inc. All rights reserved.

This study reviewed clinical data from dogs diagnosed with sudden acquired retinal degeneration syndrome (SARDS) in western Canada. Medical records from the Western College of Veterinary Medicine from 2002 to 2016 showed that 93 cases of SARDS were diagnosed based on presentation for sudden blindness and a bilaterally extinguished electroretinogram. The most common pure breeds were the miniature schnauzer, dachshund, and pug. The mean age at diagnosis was 8.1 years and males and females were equally affected. Most of the dogs were presented with normal non-chromatic, but abnormal chromatic pupillary light reflexes. The incidence of retinal degeneration as detected via ophthalmoscopy increased over time after SARDS diagnosis. Polyuria, polydipsia, polyphagia, weight gain, elevated liver enzyme values, isosthenuria, and proteinuria were common clinical and laboratory findings. Chromatic pupillary light reflex testing may be more valuable than non-chromatic pupillary light testing in detecting pupil response abnormalities in dogs with SARDS, although electroretinography remains the definitive diagnostic test.
