OBJECTIVES The high mortality among HIV/tuberculosis (TB) coinfected patients in Eastern Europe is partly explained by the high prevalence of drug-resistant TB. It remains unclear whether outcomes of HIV/TB patients with rifampicin/isoniazid-susceptible TB in Eastern Europe differ from those in Western Europe or Latin America. METHODS One-year mortality of HIV-positive patients with rifampicin/isoniazid-susceptible TB in Eastern Europe, Western Europe, and Latin America was analys...

The high mortality among HIV/tuberculosis (TB) coinfected patients in Eastern Europe is partly explained by the high prevalence of drug-resistant TB. It remains unclear whether outcomes of HIV/TB patients with rifampicin/isoniazid-susceptible TB in Eastern Europe differ from those in Western Europe or Latin America. One-year mortality of HIV-positive patients with rifampicin/isoniazid-susceptible TB in Eastern Europe, Western Europe, and Latin America was analysed and compared in a prospective observational cohort study. Factors associated with death were analysed using Cox regression modelsRESULTS:: Three hundred and forty-one patients were included (Eastern Europe 127, Western Europe 165, Latin America 49). Proportions of patients with disseminated TB (50, 58, 59%) and initiating rifampicin + isoniazid + pyrazinamide-based treatment (93, 94, 94%) were similar in Eastern Europe, Western Europe, and Latin America respectively, whereas receipt of antiretroviral therapy at baseline and after 12 months was lower in Eastern Europe (17, 39, 39%, and 69, 94, 89%). The 1-year probability of death was 16% (95% confidence interval 11-24%) in Eastern Europe, vs. 4% (2-9%) in Western Europe and 9% (3-21%) in Latin America; P death compared with those in Western Europe/Latin America (aHR 2.79 (1.15-6.76); P = 0.023). Despite comparable use of recommended anti-TB treatment, mortality of patients with rifampicin/isoniazid-susceptible TB remained higher in Eastern Europe when compared with Western Europe/Latin America. The high mortality in Eastern Europe was only partially explained by IDU, use of ART and CD4 cell count. These results call for improvement of care for TB/HIV patients in Eastern Europe.

SAMHD1 is a human restriction factor that prevents efficient infection of macrophages, dendritic cells and resting CD4+ T cells by HIV-1. Here we explored the antiviral activity and biochemical properties of human SAMHD1 polymorphisms. Our studies focused on human SAMHD1 polymorphisms that were previously identified as evolving under positive selection for rapid amino acid replacement during primate speciation. The different human SAMHD1 polymorphisms were tested for their ability to block HIV-1, HIV-2 and equine infectious anemia virus (EIAV). All studied SAMHD1 variants block HIV-1, HIV-2 and EIAV infection when compared to wild type. We found that these variants did not lose their ability to oligomerize or to bind RNA. Furthermore, all tested variants were susceptible to degradation by Vpx, and localized to the nuclear compartment. We tested the ability of human SAMHD1 polymorphisms to decrease the dNTP cellular levels. In agreement, none of the different SAMHD1 variants lost their ability to reduce cellular levels of dNTPs. Finally, we found that none of the tested human SAMHD1 polymorphisms affected the ability of the protein to block LINE-1 retrotransposition. - Highlights: • Human SAMHD1 single-nucleotide polymorphisms block HIV-1 and HIV-2 infection. • SAMHD1 polymorphisms do not affect its ability to block LINE-1 retrotransposition. • SAMHD1 polymorphisms decrease the cellular levels of dNTPs.

To assess the antioxidant status in HIV positive children. HIV positive children under the age group of 3-12 years from lower socio-economic strata were chosen for the study (Group 1). The values were compared with normal children (Group 2) not suffering from any disease in the same age group and similar socio-economic strata. The antioxidants chosen for the present study were vitamin A (Retinol), vitamin C (Ascorbic acid) and vitamin E (alpha tocopherol). Results obtained were subjected to statistical analysis using student 't' test (in the present study 'z' test was applied). The antioxidants vitamin A, C and E decreased in HIV positive children as compared to controls. Vitamin A was significant to the level of pchildren is due to increased utilization of antioxidant micronutrients because of increased oxidative stress caused due to free radicals.

In this issue of Clinical and Vaccine Immunology, K. Jensen et al. (Clin Vaccine Immunol 24:e00360-16, 2017, https://doi.org/10.1128/CVI.00360-16) describe a dual-purpose attenuated Mycobacterium tuberculosis-simian immunodeficiency virus vaccine (AMTB-SIV). Interestingly, immunized infant macaques required fewer oral exposures to SIV to become infected relative to nonimmunized animals. The authors hypothesized that augmented susceptibility to SIV was due to activation of CD4+ T cells through trained immunity. This commentary explores the possible relationship between trained immunity, enhanced CD4 T cell responses, and increased susceptibility to human immunodeficiency virus (HIV).

It is not well understood how infection with HIV and prior experience of sexual violence affects sexual behavior in African women. We describe factors influencing current sexual practices of Rwandan women living with or without HIV/AIDS. By design, 75% of participants were HIV positive and ~50% reported having experienced genocidal rape. Univariate and multivariate logistic regression models were fit to describe demographic and clinical characteristics that influenced sexual behavior in the previous 6 months, condom use, history of transactional sex, and prior infection with a non-HIV sexually transmitted disease. Respondents’ age, where they lived, whether or not they lived with a husband or partner, experience of sexual trauma, CD4 count, CES-D and PTSD scores were strongly associated with risky sexual behavior and infection with non-HIV STI. HIV positive women with a history of sexual violence in the contexts of war and conflict may be susceptible to some high-risk sexual behaviors. PMID:25488169

Mucosal associated lymphoid tissues are major targets of HIV during early infection and disease progression but can also provide a viral safe haven during highly active antiretroviral therapy. Among these tissues, the tonsils remain enigmatic regarding their status as primary and/or secondary sites of retroviral infection. To dissect the mechanisms underlying susceptibility to HIV in this compartment, isolated tonsil cells were studied for phenotypic and functional characteristics, which may account for their permissiveness to infection. For this, tonsil cells and PBMC were infected in parallel with HIV, and viral replication was monitored by p24 ELISA. Our results demonstrate that unstimulated tonsil cells were more readily infected than PBMC with HIV. Phenotypic characterization of the tonsil cells revealed heterogeneous lymphoid populations but with increased expression of early activation markers and the viral co-receptor CXCR4, relative to PBMC, all of which may contribute to viral susceptibility. Furthermore, the cytokine microenvironment appeared to be key in facilitating HIV infection and tonsil-secreted products enhanced HIV infection in PBMC. Of the cytokines detected in the tonsil supernatants, TH2 cytokines, particularly IL-4, promoted HIV infection and replication. Interestingly, this TH2 profile appeared to dominate, even in the presence of the TH1 cytokine IFNgamma and the anti-viral factor IFNalpha, likely due to the enhanced expression of suppressor of cytokine signaling (SOCS) proteins, which may disengage IFN signaling. These and other local environmental factors may render tonsil cells increasingly susceptible to HIV infection.

HIV rapid diagnostic tests have enabled widespread implementation of HIV programs in resource-limited settings. If the tests used in the diagnostic algorithm are susceptible to the same cause for false positivity, a false-positive diagnosis may result in devastating consequences. In resource-limited settings, the lack of routine confirmatory testing, compounded by incorrect interpretation of weak positive test lines and use of tie-breaker algorithms, can leave a false-positive diagnosis undetected. We propose that heightened CD5+ and early B-lymphocyte response polyclonal cross-reactivity are a major cause of HIV false positivity in certain settings; thus, test performance may vary significantly in different geographical areas and populations. There is an urgent need for policy makers to recognize that HIV rapid diagnostic tests are screening tests and mandate confirmatory testing before reporting an HIV-positive result. In addition, weak positive results should not be recognized as valid except in the screening of blood donors.

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

The prevalence and cotrimoxazole susceptibility of Streptococcus pneumoniae isolated from sputum of 100 HIV-positive patients attending the Nigeria Institute of Medical Research clinic was investigated using standard microbiological methods. Eleven of the sputum specimens grew Streptococcus pneumoniae. Antimicrobial susceptibility test showed that all the isolates were sensitive to amoxicillin, augmentin, erythromycin and chloramphenicol but were resistant to cotrimoxazole. Continuous surveillance of S pneumoniae in sputum samples of HIV-positive subjects in this environment is necessary in order to regulate treatment regimen, considering that cotrimoxazole is the drug recommended by WHO for respiratory infections in HIV patients.

The scale item with the highest score was faith. This probably derives from the fact that Aids is incurable, transmissible and generates negative stigma, in addition to its relation with the idea of imminent death. In conclusion, measuring hope among HIV patients through the use of an instrument permits intervention assessment and planning, promoting assistance and motivation to live better and maintain a hopeful attitude.

Cuba experienced a substantial increase in the number of HIV cases in 1996 due primarily to a growth of foreign tourism and an increase in prostitution, health officials said. The Juventud Rebelde newspaper said that since HIV/AIDS testing began in 1985, government-run hospitals and clinics have detected 1609 HIV-positive cases. In 1995 the total was reported at 1196, meaning that 413 new cases were detected in 1996. This compared with only 97 new cases reported during 1995. HIV infection among the island's 11 million inhabitants has remained relatively low due to a massive testing program and a public health infrastructure that provides universal and free medical treatment. Cuba was a pioneer in the use of interferon on those testing HIV-positive. Cuba produces its own interferon, which prolongs the life expectancy of patients, and also reagents for AIDS testing. There are special sanitariums for AIDS patients in most of Cuba's 12 provinces. Cuban adults who test HIV-positive are required to enter the sanitarium in a policy reminiscent of the way tuberculosis patients were tested in the US earlier in this century. Officials said the isolation of patients in sanitariums has been somewhat relaxed over past years by introducing greater flexibility in allowing persons who are considered reliable to live at home or make prolonged visits. full text

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

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

Full Text Available Introduction: HIV-1 group O (HIV-O is a rare HIV-1 variant characterized by a high number of polymorphisms, especially in the integrase gene, e.g. positions L74I, S153A, G163Q and T206S. As HIV-O integrase enzymes have not previously been studied, our aim was to assess the impact of HIV-O integrase polymorphisms on susceptibility to integrase inhibitors and emergence of resistance associated mutations. Viruses and Methods: We cloned and purified integrase proteins from each of HIV-1 Group O clades A (HIV-O/A and B (HIV-O/B, a HIV-O divergent strain (HIV-O/Div, and HIV-1 group M (subtype B, HIV-M/B and characterized these enzymes for susceptibility to integrase strand transfer inhibitors (INSTIs in cell-free assays and in tissue culture, in the absence or presence of varying concentrations of several INSTIs. The inhibition constant (Ki and IC50 were calculated and compared for HIV-M and HIV-O integrases. Selections for resistance-related mutations were performed using cord blood mononuclear cells and increasing concentration of INSTIs. Results: HIV-O integrase and viruses were more susceptible to raltegravir (RAL in competitive inhibition assays and in tissue culture than were HIV-M enzymes and viruses, respectively. During selection, we observed different pathways of resistance depending on the drug and clade. Mutations selected in HIV-O can be classified as follows: (1 mutations described for HIV-M such as T97A, Q148R, V151A/I (RAL, T66I, E92Q, E157Q (EVG and M50I, R263K (DTG and (2 signature mutations for HIV-O (i.e. not described in HIV-M F121C (HIV-O/B for RAL, V75I (HIV-O/A for RAL and S153V (HIV-O/A for DTG. Only the HIV-O/Div selected the Q148R mutation for RAL and R263K+M50I for DTG, as previously described for HIV-M. None of the HIV-O viruses selected either N155H or Y143C. The selection of the specific S153V mutation could be explained at the nucleotide level: HIV-O at this position contains an alanine and substitution of alanine to

HIV-positive individuals also have significantly shorter telomere length (TL in peripheral blood mononuclear cells (PBMCs and CD8+ T cells compared to HIV-negative individuals. Additionally, reduced TL has been found to be associated with chronic psychological stress. This study focused on the effects of HIV-infection and chronic stress associated with childhood trauma on telomere length, and investigated whether leukocyte TL (LTL, in particular, represents a risk factor for NCI. Eighty-three HIV-positive and 45 HIV-negative women were assessed for childhood trauma and were subjected to detailed neurocognitive testing. Blood from each participant was used to extract Deoxyribonucleic acid (DNA. Relative LTL were determined by performing real time quantitative PCR reactions as described by Cawthon et al. (2002. As expected, relative LTL in the HIV-positive individuals was significantly shorter than that of HIV-negative individuals (F = 51.56, p = <0.01. Notably, a significant positive correlation was evident between relative LTL and learning performance in the HIV-positive group. In addition, a significant negative correlation was observed between relative LTL and verbal fluency, but this association was only evident in HIV-positive individuals who had experienced trauma. Our results suggest that reduced LTL is associated with worse learning performance in HIV-positive individuals, indicating that TL could act as a susceptibility factor in increasing neurocognitive decline in HIV-infected individuals.

To understand the risks and associated factors of HIV transmission by sharing syringes among HIV-positive drug users. The survey was conducted among HIV-positive injecting drug users (IDUs-HIV+) who received HIV counseling, testing and treatment in Changsha city Infectious Disease Hospital and Hengyang city No.3 People's Hospital from July 2012 to May 2013 to understand their socio-demographic characteristics, HIV prevalence and syringe sharing. A total of 503 IDUs-HIV+ were involved in and provided the contact list of 2 460 drug users who had the syringe sharing experience over one month with IDUs-HIV+. 420 IDUs-HIV+ among 503 were defined as infection sources due to sharing syringe with at least one drug user. Among them, 234 HIV-negative persons were in control group, and 186 HIV-positive were in cased group. A total of 1 220 drug users were followed up among 2 460 and defined as vulnerable population. The HIV transmission rate was calculated based on the HIV prevalence among vulnerable population. Based on the result of HIV transmission to vulnerable population from 420 infection sources, case-control study and the multivariate logistic regression analysis were adopted to explore the associated factors of HIV transmission among IDUs-HIV+. As the sources of HIV transmission, 420 IDUs-HIV+ had an average duration of (4.5 ± 1.2) years for drug use. As a susceptible population, 1 220 drug users sharing syringes with the 420 IDUs-HIV+ had an average duration of (1.1 ± 0.5) years for drug use. There were 238 HIV-positive persons among 1 220 vulnerable drug users, with a transmission rate of 0.57. In the case-control study, the proportion of male subjects was 87.1% (162/186) in the case group, which was higher than that in the control group (77.8%, 182/234). The proportion of subjects who received support after knowing their HIV infection status was 51.1% (95/186) in the case group, which was lower than that in the control group (79.5%, 186/234). The proportion of

Chorioamnionitis is an important risk factor for vertical transmission of HIV/AIDS. We compared the prevalence and correlates of histologic chorioamnionitis (HCA) in HIV-positive and HIV-negative pregnant women. HIV-positive and -negative parturients were interviewed, examined and had their placentas examined histologically for chorioamnionitis. Data regarding HIV were also retrieved from their hospital records. A total of 298 parturients (150 HIV positive and 148 HIV negative) were enrolled. The two groups were similar in socio-demographic and obstetric parameters except for age. The prevalence of HCA was 57.1% in HIV-positive women and 61.6% in HIV-negative women (p = 0.43). HCA staging was associated with the number of intrapartum vaginal examinations in HIV-positive subjects and nulliparity in HIV-negative subjects. The number of intrapartum vaginal examinations and coitus in the week prior to delivery significantly affected the grade of HCA in HIV-negative subjects. The prevalence of HCA in both HIV-positive and HIV-negative is high. Most variables did not affect the occurrence of HCA in both groups studied except number of intrapartum examinations, coitus in the preceding one week and nulliparity, which were related to severity of the disease. © The Author(s) 2016.
Full Text Available Individual differences in susceptibility to human immunodeficiency virus type 1 (HIV-1 infection have been of interest for decades. We aimed to determine the contribution of large isoform of Mammalian DnaJ (MRJ-L, a HIV-1 Vpr-interacting cellular protein, to this natural variation. Expression of MRJ-L in monocyte-derived macrophages was significantly higher in HIV-infected individuals (n = 31 than their uninfected counterparts (n = 27 (p = 0.009. Fifty male homosexual subjects (20 of them are HIV-1 positive were further recruited to examine the association between MRJ-L levels and occurrence of HIV infection. Bayesian multiple logistic regression revealed that playing a receptive role and increased levels of MRJ-L in macrophages were two risk factors for HIV-1 infection. A 1% rise in MRJ-L expression was associated with a 1.13 fold (95% CrI 1.06–1.29 increase in odds of contracting HIV-1 infection. Ex vivo experiments revealed that MRJ-L facilitated Vpr-dependent nuclear localization of virus. Infection of macrophage-tropic strain is a critical step in HIV-1 transmission. MRJ-L is a critical factor in this process; hence, subjects with higher macrophage MRJ-L levels are more vulnerable to HIV-1 infection.

The prevalence of HIV in Pakistan is less than 0.1%, but is feared to be spreading among the general population rapidly. Screening tests for HIV is based on antibody detection. There seems to be little knowledge regarding the interpretation of HIV results among the population. Most often the patients are being issued a positive HIV report based on single screening test when in fact it should be confirmed before issuing a positive HIV result. There is a lot of stigma associated with the disease in Pakistan, on the other hand the test is done mostly without counselling services hence causing physical and mental trauma to the patients.

We performed a prospective, blind, controlled study on wound infection after implant surgery involving 41 procedures in patients infected with the human immunodeficiency virus (HIV) and 141 in HIV-negative patients. The patients were staged clinically and the CD4 cell count determined. Wound infection was assessed using the asepsis wound score. A risk category was allocated to account for presurgical contamination. In HIV-positive patients, with no preoperative contamination, the incidence of wound infection (3.5%) was comparable with that of the HIV-negative group (5%; p = 0.396). The CD4 cell count did not affect the incidence of infection (r = 0.16). When there was preoperative contamination, the incidence of infection in HIV-positive patients increased markedly (42%) compared with that in HIV-negative patients (11%; p = 0.084). Our results show that when no contamination has occurred implant surgery may be undertaken safely in HIV-positive patients.

This review aims to summarize recent developments in the epidemiology and management of sexually transmitted infections in HIV positive individuals. It will also discuss briefly the legal aspects of disclosure in relation to HIV transmission. There has been a dramatic increase in the reported number of cases of syphilis globally in recent years. In the United Kingdom this has mainly been observed among HIV positive men who have sex with men (MSM). Since 2003 there have been a series of outbreaks of lymphogranuloma venereum reported in several European cities occurring mostly in HIV positive MSM. Sexual transmission of hepatitis C is increasing and appears to be more common in HIV positive MSM. Legal issues regarding HIV transmission have also come to the fore, becoming an important part of the discussion of sexual health with an HIV positive patient. Increases in sexually transmitted infection among HIV positive individuals suggest a worrying lack of adherence to safe sex guidelines and needs to be addressed urgently. The transmission of HIV is facilitated by the presence of certain sexually transmitted infections. Management of sexual health is an essential part of HIV care.

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

Social stigma has been inextricably linked with HIV and AIDS since the epidemic erupted in the early 1980s. The stigma that has built up around HIV and AIDS is generally regarded as having a negative impact on the quality of life of HIV-positive people and on general prevention efforts. Current attempts to combat HIV-related stigma focus on increasing the acceptance of HIV among the stigmatizing public and stigmatized individuals alike. In this, the global HIV-positive community is being increasingly called upon to ;humanize' the virus, not least through public displays of HIV 'positive' health and public ;positive' speaking. This article critically explores the constitutive effects and inherent power relations of HIV Positive Speakers' Bureaus (PSBs) as a platform for such a display. Adopting a post-structuralist discourse analytic approach, we explore accounts of positive-speaking and HIV health from HIV-related non-government organizations in India and in PSB training manuals. In particular, we highlight ways in which positive-speaking in India can be seen to have significant (re)stigmatizing effects by way of ambivalent and hyper-real configurations of HIV 'positive' identity and life.

Aerobic endurance is an important aspect of physical fitness that enables individuals living with HIV to endure in the work place as well as in agricultural operations in order to earn a living and improve their quality of life. However, despite high HIV prevalence rates, the aerobic endurance status of young Malawians living with HIV remains unknown. The objective of this study was to determine the difference in VO2max between HIV-negative and HIV-positive individuals in Blantyre, Malawi. Fifty five participants (17 males and 38 females) who have HIV and were not taking antiretroviral medication and 78 HIV-negative participants (45 males and 33 females) performed the Rockport submaximal treadmill exercise test. Measures of body weight, post-exercise heart rate and time to walk one mile were obtained and used to predict VO2max. Comparisons between groups were adjusted for age differences using analysis of covariance (ANCOVA). VO2max was significantly lower in HIV-positive subjects [31.1, 28.7 - 33.5mL.kg-1.min-1(mean, 95% CI)] compared with HIV-negative subjects [56.2, 54.3 - 58.1mL.kg-1.min-1]. Aerobic endurance was markedly reduced in HIV-positive participants compared with HIV-negative participants. Findings of the current study implicate factors associated with the HIV infection as contributors to a decreased aerobic endurance in people living with HIV.

Full Text Available Co-infection with HIV and visceral leishmaniasis is an important consideration in treatment of either disease in endemic areas. Diagnosis of HIV in resource-limited settings relies on rapid diagnostic tests used together in an algorithm. A limitation of the HIV diagnostic algorithm is that it is vulnerable to falsely positive reactions due to cross reactivity. It has been postulated that visceral leishmaniasis (VL infection can increase this risk of false positive HIV results. This cross sectional study compared the risk of false positive HIV results in VL patients with non-VL individuals.Participants were recruited from 2 sites in Ethiopia. The Ethiopian algorithm of a tiebreaker using 3 rapid diagnostic tests (RDTs was used to test for HIV. The gold standard test was the Western Blot, with indeterminate results resolved by PCR testing. Every RDT screen positive individual was included for testing with the gold standard along with 10% of all negatives. The final analysis included 89 VL and 405 non-VL patients. HIV prevalence was found to be 12.8% (47/ 367 in the VL group compared to 7.9% (200/2526 in the non-VL group. The RDT algorithm in the VL group yielded 47 positives, 4 false positives, and 38 negatives. The same algorithm for those without VL had 200 positives, 14 false positives, and 191 negatives. Specificity and positive predictive value for the group with VL was less than the non-VL group; however, the difference was not found to be significant (p = 0.52 and p = 0.76, respectively.The test algorithm yielded a high number of HIV false positive results. However, we were unable to demonstrate a significant difference between groups with and without VL disease. This suggests that the presence of endemic visceral leishmaniasis alone cannot account for the high number of false positive HIV results in our study.

Observational data from Eastern Europe on the management and outcome of multi-drug-resistant tuberculosis (MDR TB) in HIV positive populations remain sparse in the English-language literature. We compared clinical characteristics and outcomes of 55 patients who were diagnosed with HIV and MDR TB in Eastern Europe between 2004 and 2006 to 89 patients whose Mycobacterium tuberculosis isolates were susceptible to isoniazid and rifampicin. Patients with HIV and MDR TB were young and predominantly male with high rates of intravenous drug use, imprisonment and hepatitis C co-infection. Eighty-four per cent of patients with MDR TB had no history of previous TB drug exposure suggesting that the majority of MDR TB resulted from transmission of drug-resistant M. tuberculosis. The use of non-standardized tuberculosis treatment was common, and the use of antiretroviral therapy infrequent. Compared to those with susceptible tuberculosis, patients with MDR TB were less likely to achieve cure or complete tuberculosis treatment (21.8% vs. 62.9%, p < 0.0001), and they were more likely to die (65.5% vs. 27.0%, p < 0.0001). Our study documents suboptimal management and poor outcomes in HIV positive patients with MDR TB. Implementation of WHO guidelines, rapid TB diagnostics and TB drug susceptibility testing for all patients remain a priority in this region. Copyright © 2013 The British Infection Association.

We prospectively studied 37 HIV-1 uninfected persons engaging in repeated high risk sexual activity with an HIV-1 infected partner, as well as 18 of their infected partners. Only one subject (3%) demonstrated the homozygous 32-bp deletion delta32delta32 of the HIV-1 co-receptor CCR5. CD4+ cells from all high risk subjects except the delta32delta32 CCR5 homozygote were susceptible in vitro to both CCR5-dependent and CXCR4-dependent HIV-1 strains. Median HIV-1 plasma RNA levels of the infected partners were not significantly different from levels of matched infected controls. Thirteen subjects demonstrated HIV-1 specific CTL at one or more visits, and these activities were more commonly observed in persons with the wild type CCR5 genotype. These results indicate that cellular immunity rather than inheritance of the delta32 CCR5 mutation accounts more often for persistently HIV-1-resistant cases.
Full Text Available Abstract Background Rapid HIV tests provide same-day results and are widely used in HIV testing programs in areas with limited personnel and laboratory infrastructure. The Uganda Ministry of Health currently recommends the serial rapid testing algorithm with Determine, STAT-PAK, and Uni-Gold for diagnosis of HIV infection. Using this algorithm, individuals who test positive on Determine, negative to STAT-PAK and positive to Uni-Gold are reported as HIV positive. We conducted further testing on this subgroup of samples using qualitative DNA PCR to assess the potential for false positive tests in this situation. Results Of the 3388 individuals who were tested, 984 were HIV positive on two consecutive tests, and 29 were considered positive by a tiebreaker (positive on Determine, negative on STAT-PAK, and positive on Uni-Gold. However, when the 29 samples were further tested using qualitative DNA PCR, 14 (48.2% were HIV negative. Conclusion Although this study was not primarily designed to assess the validity of rapid HIV tests and thus only a subset of the samples were retested, the findings show a potential for false positive HIV results in the subset of individuals who test positive when a tiebreaker test is used in serial testing. These findings highlight a need for confirmatory testing for this category of individuals.

People are living longer and healthier with HIV infection because of successful combination antiretroviral therapies. HIV treatment beliefs are often associated with sexual practices among people living with HIV/AIDS but these associations may depend on the HIV status of sex partners. In a sample of 158 HIV positive men and women who were receiving HIV treatments, we examined the association between HIV treatment beliefs, HIV transmission risk perceptions, medication adherence, viral load and engaging in unprotected intercourse with any sex partners and specifically with sex partners who were not HIV positive (non-concordant). Results showed having missed medications in the past two days and treatment-related beliefs were significantly associated with engaging in unprotected intercourse with all sex partners as well as non-concordant partners. However, multivariate models showed that only treatment beliefs were significantly associated with engaging in unprotected intercourse with non-concordant partners. These results extend past research by demonstrating that the HIV status of sex partners sets the context for whether prevention-related treatment beliefs are associated with HIV transmission risk behaviors among people living with HIV/AIDS.

HIV infections frequently affect the oral cavity, and local changes may be utilized as indicators of immunosuppression in HIV-positive patients. Morphometric and morphological features of the lining, masticatory, and specialized epithelium of the oral mucosa were studied in 12 HIV-positive and 12 HIV-negative patients autopsied from 2007 to 2010. Mucosal samples from the cheek, gingival, and tongue of 24 individuals were fixed in Carnoy solution and stained with hematoxylin-eosin. Various morphometric characteristics (epithelial thickness, number of cell layers, mean cell diameter) and morphological parameters (basal layer hyperplasia, exocytosis of inflammatory cells, glycogenic acanthosis, cell ballooning degeneration) were then measured. The HIV-positive group had a greater epithelial thickness (mean: 304.4μm) and a higher mean cell diameter (11.84μm), whereas the HIV-negative group had more epithelial layers (26.7). Basal layer hyperplasia did not differ significantly between the two groups, but exocytosis of inflammatory cells, glycogenic acanthosis, cell ballooning, and spongiosis were more prevalent in the HIV-positive group. Our findings demonstrate that HIV infection causes diverse epithelial changes in the oral cavity, including thickening, increased cell diameter, increased migration of inflammatory cells, and inter- and intra-cellular edema.

Full Text Available Background and objectives. HIV/AIDS and suicidal behaviour are major public health concerns. The aim of this study was to examine the relationship between hopelessness, depression and suicidal ideation in HIV-infected persons. Methods. The sample consisted of all adult volunteers attending a voluntary counselling and testing (VCT HIV clinic at a university affiliated state hospital. Suicidal ideation and depression were measured using the Beck Hopelessness Scale (BHS and the Beck Depression Inventory (BDI, respectively, at two intervals, viz. 72 hours and 6 weeks after HIV diagnosis. Results. Of the 156 patients who tested positive for HIV, 32 (20.5% had a hopelessness score of 9 or above on the BHS and 130 patients (82.8% were depressed according to the BDI at 72 hours after diagnosis. Of the 109 patients assessed 6 weeks after diagnosis, 32 (28.8% had a hopelessness score of >9 on the BHS and 86 (78.2% were depressed according to the BDI. A moderately positive correlation at both time periods was found between hopelessness and depression. A ROC analysis showed optimal sensitivity, indicating that the HIV-positive depressed patients were at risk for suicidal behaviour. Conclusion. The significant correlations between hopelessness, depression and suicidal ideation are important markers that should alert healthcare professionals to underlying suicide risks in HIV-positive patients. Early recognition of this and suicide prevention strategies should be incorporated into the treatment offered at VCT HIV clinics.

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

HIV-positive females are more likely to have abnormal Pap smears than HIV-negative women. These abnormal Pap smears are usually associated with low CD4 cell counts and human papilloma virus infection. This was a prospective hospital-based study from April 2013 till March 2014. A total of 250 (both symptomatic and asymptomatic) HIV-positive females were examined in Gynaecology OPD at R.C.S.M. G.M.C and C.P.R. Hospital, Kolhapur, and their cervical smears were taken. They were categorized as per modified Bethesda system 2001. The findings in HIV-positive women were correlated with risk factors (age, disease duration, CD4 count and ART use). To study the spectrum of cytological abnormalities on Pap smear in HIV-positive females and classify precancerous and cancerous lesions in HIV-positive females according to Bethesda system 2001 and to be familiar with terminology and morphological criteria of Bethesda system 2001. To study the association of Pap smears abnormalities among HIV-positive women with their immune status (CD4 count). NILM is the commonest finding (83.2 %) which is subdivided into non-inflammatory, non-specific and specific inflammatory and atrophic smears. Candida vaginitis was the commonest cause of specific inflammatory condition accounted for (2.52 %) of all inflammatory smears. The percentage of squamous cell abnormalities was 12 %: ASCUS + ASC-H-6.22 %, LSIL-2.10 %, HSIL-3.4 % and SCC-0.8 %. The highest incidence of intraepithelial lesions in HIV-positive females was in the age group 31-40 years. There is no association of Pap smear abnormalities among HIV-positive women with their immune status (CD4 count) and duration of ART. Periodic, regular gynaecologic and Pap smear examination would help in early detection of intraepithelial lesions and their treatment so as to prevent invasive malignancy and mortality.
Full Text Available Background. In the medical sense, stigma has been defined as the collection of negative attitudes and beliefs that are directed at people living with a particular condition or disease process. A cohort study was conducted to explore the HIV stigma that is perceived by HIV-positive individuals versus that perceived by the general population within a community-based dental clinic. Methods. Two separate and independent cross-sectional surveys, the Berger Stigma Scale and the Rutgers-Modified Berger Stigma Scale, were employed in order to analyze the stigma factors of an HIV-positive population versus an HIV-negative general population, respectively. The HIV stigma factors studied included personalized stigma, disclosure concerns, negative self-image, and concern with public attitudes. Results. The total stigma scale scores for the studied HIV-positive population were significantly lower than the total stigma scale scores for the studied HIV-negative population (P < 0.05. Conclusion. Interestingly, there is a misplaced expectation by the general population that HIV-positive individuals experience more stigma than the HIV-positive population in the clinic actually reported. Interventions to reduce HIV stigma should be an integral component of comprehensive care for all patients.

Full Text Available Abstract Objective To compare the prevalence of gynaecological conditions among HIV infected and non-infected pregnant women. Methods Two thousand and eight (2008 pregnant women were screened for HIV, lower genital tract infections and lower genital tract neoplasia at booking antenatal visit. Results About 10% (198/2008 were HIV positive. All lower genital tract infections except candidiasis were more prevalent among HIV positive compared to HIV negative women: vaginal candidiasis (36.9% vs 35.4%; p = 0.678, Trichomoniasis (21.2% vs 10.6%; p p p = 0.026, syphilis (35.9% vs 10.6%; p Chlamydia trachomatis (38.4% vs 7.1%; p p p Conclusion We conclude that (i sexually transmitted infections (STIs are common in both HIV positive and HIV negative pregnant women in Cameroon, and (ii STIs and preinvasive cervical lesions are more prevalent in HIV-infected pregnant women compared to their non-infected compatriots. We recommend routine screening and treatment of STIs during antenatal care in Cameroon and other countries with similar social profiles.

Highly active anti-retroviral therapy has transformed HIV into a chronic disease with a long-term asymptomatic phase. As a result, emphasis is shifting to other effects of the virus, aside from immunosuppression and mortality. We have reviewed the current evidence for an association between HIV infection and poor fracture healing. The increased prevalence of osteoporosis and fragility fractures in HIV patients is well recognised. The suggestion that this may be purely as a result of highly active anti-retroviral therapy has been largely rejected. Apart from directly impeding cellular function in bone remodelling, HIV infection is known to cause derangement in the levels of those cytokines involved in fracture healing (particularly tumour necrosis factor-alpha) and appears to impair the blood supply of bone. Many other factors complicate this issue, including a reduced body mass index, suboptimal nutrition, the effects of anti-retroviral drugs and the avoidance of operative intervention because of high rates of wound infection. However, there are sound molecular and biochemical hypotheses for a direct relationship between HIV infection and impaired fracture healing, and the rewards for further knowledge in this area are extensive in terms of optimised fracture management, reduced patient morbidity and educated resource allocation. Further investigation in this area is overdue.

The link between HIV stigma with substance use is understudied. We characterized individuals with high HIV stigma and examined whether HIV stigma contributes to substance use among HIV-positive Russians reporting risky alcohol use. We analyzed data from HERMITAGE, a randomized controlled trial of 700 people living with HIV/AIDS (PLWHA) with past 6-month risky sex and risky alcohol use in St. Petersburg, Russia (2007-2011). Participants who were female and reported depressive symptoms and lower social support were more likely to endorse high HIV stigma (all p's < 0.001). In adjusted models, high HIV stigma was not significantly associated with the primary outcome unhealthy substance use and was not consistently associated with secondary substance use outcomes. Interventions to enhance social and mental health support for PLWHA, particularly women, may reduce stigma, though such reductions may not correspond to substantial decreases in substance use among this population.

Full Text Available Abstract Background Patients with HIV are subject to development of HIV metabolic syndrome characterized by dyslipidemia, lipodystrophy and insulin resistance secondary to highly active antiretroviral therapy (HAART. Rosuvastatin is a highly potent HMG-CoA reductase inhibitor. Rosuvastatin is effective at lowering LDL and poses a low risk for drug-drug interaction as it does not share the same metabolic pathway as HAART drugs. This study sought to determine the efficacy of rosuvastatin on lipid parameters in HIV positive patients with HIV metabolic syndrome. Results Mean TC decreased from 6.54 to 4.89 mmol/L (25.0% reduction, p Conclusion This study found that rosuvastatin is effective at improving potentially atherogenic lipid parameters in HIV-positive patients. The lipid changes we observed were of a smaller magnitude compared to non-HIV subjects. Our results are further supported by a small, pilot trial examining rosuvastatin effectiveness in HIV who reported similar median changes from baseline of -21.7% (TC, -22.4% (LDL-C, -30.1% (TG with the exception of a 28.5% median increase in HDL. In light of the results revealed by this pilot study, clinicians may want to consider a possible resistance to statin therapy when treating patients with HIV metabolic syndrome.

Full Text Available INTRODUCTION: In HIV-infected patients, colonization of the oral cavity by potential pathogenic yeast may lead to development of systemic fungemia. We evaluated the prevalence of yeast in the oral cavity of Brazilian HIV-positive patients and verified whether or not the species characterized were enzymatically active. Furthermore, the species identified were tested for their susceptibility to antifungal treatment. METHODS: Patient saliva and oropharyngeal candidiasis samples were collected from 60 seropositive HIV patients and identified by the API20C system. Enzymatic activity was evaluated by the production of proteinase and phospholipase. Susceptibility to antifungal treatments were determined using the broth microdilution method. RESULTS: the most commonly isolated species were C. albicans (51.56% followed by non-albicans Candida species (43.73%, Trichosporon mucoides (3.12% and Kodamaea ohmeri (1.56%. Oral colonization by association of different species was observed in 42% of the patients. Enzymatic activity was verified in most of species isolated, except for C. glabrata, C. lusitaniae and C. guilliermondii. Resistance to Fluconazole and Amphotericin B was observed in isolates of C. albicans, C. glabrata, C. parapsilosis, C. krusei, and K. ohmeri. CONCLUSION: HIV-positive patients are orally colonized by single or multiple species of yeast that are occasionally resistant to Fluconazole or Amphotericin B.

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

Commercial sex worker is one of the groups with the highest level of susceptibility against HIV infection. They are 13,5 fold more prone to a living with HIV infection than the female of non commercial sex workers. Moreover, these commercial sex workers are also stigmatized with social sanction and discrimination against people with HIV-AIDS. The society mostly avoid them, deject them, isolate them, insult them, despise them, distrust them, and even go against the existence of those suffering from or infected by HIV-AIDS. Thus, stigmatizing and discrimination are basicly highly prohibited since they can incur higher social problems. It is also vital to handle the spread of HIV-AIDS in the society as soon as possible in the attempt of fighting against the spread of the disease. Hence, being broad minded, tolerant, and caring towards them as well as working hand in hand with the community are expected to diminish, minimize, and even eradicate the outbreak of HIV-AIDS. Caring towards those suffering from the infection without stigmatizing them and discriminating them will be one of the first measurements to take to improve what is needed to prevent the prevalence and spread of the disease. Thus, the primary objective of this research is to know the perception of female commercial sex workers on the susceptibility of HIV-AIDS in Yogyakarta. The research participants were selected from three localizations in Yogyakarta namely Pasar Kembang, Bongsuwung, and Giwangan. It is revealed that the participants had a good perception on the susceptibility of AIDS infection as seen from the fact there are free avalaible condoms for them to use everytime they have a sexual intercourse with the clients. All participants were aware of their high susceptibility against the infection of STIs/HIV/AIDS and thus they want to save their skin from those diseases. Also they had a good knowledge that having an intercourse without condom may get them infected.

Open tibia fractures are common injuries, particularly in developing countries.Pedestrian or bicycle to motor car contact is the most common mechanism. These injuries result in high morbidity and often long-term disability. HIV infection complicates open fractures by raising the incidence of infectionin the open wound (5 of 7 patients in our series). This risk may be compounded if internal fixation techniques are used (5 of 12 HIV patients with internal fixation of any open fracture). There is also a suggestion that HIV may delay bone union (4 of 7 patients united at 6 months). External fixation offers an alternative method of fracture stabilisation. It avoids the risks associated with putting metal-ware in the wound, but creates a new issue of pin track sepsis. We found that pin track infection was more common in patients with HIV, but the rate at which pins required removal was 7%. We consider external fixation to be a lower-risk strategy than internal fixation in such patients but open fracture wound sepsis remains a problem. We have not yet demonstrated a difference in severity or frequency of complications in patients of low CD4 count, but logically one expects septic complications to increase as CD4 count falls. Antiretroviral medication decreases viral load and elevates the CD4 count. Research is underway regarding potential effectiveness of such drugs in reducing wound and fracture healing complications. Above all, meticulous and timely all-round care is required to achieve satisfactory results in immune-compromised patients. This includes, debridement, bony stability, and soft-tissue reconstruction.

Cryptococcal meningitis is a mycosis encountered especially in patients with Acquired Immunodeficiency Syndrome and is fatal in the absence of treatment. Information on epidemiology, diagnosis and susceptibility profile to antifungal drugs, are scarce in Cameroon. Authors evaluated the diagnosis possibilities of the cryptococcal meningitis in Cameroon, and studied the antifungal susceptibility of isolated strains to fluconazole, used as first line treatment of the disease in Cameroon. Between December 2009 and July 2011, 146 cerebrospinal fluids obtained from HIV patients with suspicion of meningitis were analysed. The diagnosis procedure involved macroscopic and cyto-chemical analysis, India ink test, culture on Sabouraud chloramphenicol medium and antigen latex agglutination test. Antifungal susceptibility testing of isolated strains to fluconazole was done by the E-test(®) method. The diagnosis of cryptococcal meningitis gave 28.08% positive cases. Among these patients, 80% were at stages III and IV and 20% at stage I of the HIV infection, according to the WHO previous classification. Cyto-chemical analysis showed current findings in the case of cryptococcal meningitis. India ink test and latex agglutination test exhibited very high sensitivity and specificity (>94%). Fluconazole antifungal susceptibility testing gave MICs lower than 32μg/mL to 92.7% of isolated strains and MICs greater than this value to 7.3% of isolates. These results showed that cryptococcal meningitis remains a real problem among HIV infected patients in Yaoundé. The emergence of fluconazole reduced susceptibility strains is worrying. Nevertheless, efficacy of rapid detection tests is interesting because this will help in rapid diagnosis and treatment of patients. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

Despite the nutritional and health benefits of breast milk, breast milk can serve as a vector for mother-to-child HIV transmission. Most HIV-infected infants acquire HIV through breastfeeding. Paradoxically, most infants breastfed by HIV-positive women do not become infected. This is potentially attributed to anti-HIV factors in breast milk. Breast milk of HIV-negative women can inhibit HIV infection. However, the HIV-inhibitory activity of breast milk from HIV-positive mothers has not been evaluated. In addition, while significant differences in breast milk composition between transmitting and nontransmitting HIV-positive mothers have been correlated with transmission risk, the HIV-inhibitory activity of their breast milk has not been compared. This knowledge may significantly impact the design of prevention approaches in resource-limited settings that do not deny infants of HIV-positive women the health benefits of breast milk. Here, we utilized bone marrow/liver/thymus humanized mice to evaluate the in vivo HIV-inhibitory activity of breast milk obtained from HIV-positive transmitting and nontransmitting mothers. We also assessed the species specificity and biochemical characteristics of milk's in vivo HIV-inhibitory activity and its ability to inhibit other modes of HIV infection. Our results demonstrate that breast milk of HIV-positive mothers has potent HIV-inhibitory activity and indicate that breast milk can prevent multiple routes of infection. Most importantly, this activity is unique to human milk. Our results also suggest multiple factors in breast milk may contribute to its HIV-inhibitory activity. Collectively, our results support current recommendations that HIV-positive mothers in resource-limited settings exclusively breastfeed in combination with antiretroviral therapy. Approximately 240,000 children become infected with HIV annually, the majority via breastfeeding. Despite daily exposure to virus in breast milk, most infants breastfed by HIV-positive

The risk of HIV transmission via breastfeeding is well reported. We conducted a national survey in the UK to look at the current knowledge and postpartum practice of HIV physicians caring for HIV-positive pregnant women. In total, 167 questionnaires were distributed, 85 (51%) questionnaires were returned. All the respondents advised their patients against breastfeeding, 17 (23%) respondents routinely prescribed drugs for postpartum lactation suppression and 32 (43%) detailed awareness of interactions between antiretroviral therapy and dopaminergic lactation suppression agents. Thirteen respondents reported awareness of guidance on lactation suppression. The knowledge and use of lactation suppression agents appears to be low. However, its use will not only reduce postnatal mastitis and breast engorgement but will also help women deal with social pressures to breastfeed. Increased use in specific circumstances will improve the postnatal care of HIV-positive pregnant women in the UK.

Descriptive statistical analysis by means of frequency analysis was conducted. Ethical considerations and mechanisms to enhance validity and reliability are discussed. The results indicated that both HIV-positive respondents and their families face social and financial challenges due to unemployment and low income. A strength found in this research is that the majority of respondents are linked to a church, which can be a valuable platform to share information on HIV and AIDS. With regards to sharing, sources and comprehension of HIV- and AIDS-related information, it is apparent that respondents perceived that pre- and post-counselling provided an opportunity for information sharing, but that they need health care workers to spend more time with them, to be non-judgemental and to make more use of visual aids.

This is a retrospective case-control study of 62 HIV-positive women and 100 HIV-negative controls who delivered in the University of Nigeria Teaching Hospital, Enugu, from 2 August, 2002 to 31 March, 2004. The HIV-positive women were relatively younger and of lower mean parity than the HIV-negative controls. They were also significantly more likely to have positive syphilis serology, higher mean duration of labour, perineal tear, puerperal sepsis and higher mean duration of hospital stay, higher prevalence of low birth weight, birth asphyxia and more admissions to the Newborn Special Care Unit than the controls (p 0.05). All (100%) the HIV-negative and 96.8% of the seropositive women had voluntary counselling and testing (VCT). There was no maternal death in either group. Untreated maternal HIV infection is associated with adverse pregnancy outcomes in the form of increased maternal and fetal morbidities. Hence for optimal outcomes, prevention of mother-to-child transmission (PMTCT) programmes must incorporate combination drug treatment for the mother as early in pregnancy as possible.
Full Text Available Background: Dyslipidaemia, secondary to both HIV and the use of antiretroviral therapy (ART is well recognised, with HIV replication and immune status also thought to contribute to the risk. Traditionally the HIV physician has looked after HIV with primary care physicians (GP managing non-HIV-related medical issues. However with the ageing population and the effectiveness of ART the HIV physician is diversifying to focus management strategies on preventative measures also. Method: 127 subjects were recruited. All subjects were HIV-positive males without any traditional cardiovascular disease symptoms or history. Details of patients demographics, family history, statin therapy, and primary care physician contact were collected. Baseline parameters were recorded and fasting bloods taken. Results: 127 asymptomatic HIV-positive males were recruited. 74/127 (58.3% met the EACS criteria for statin prescription. 33/74 (44.6% were on a statin.

Access to HIV diagnosis is life-saving; however the use of rapid diagnostic tests in combination is vulnerable to wrongly diagnosing HIV infection when both screening tests give a false positive result. Misclassification of HIV patients can also occur due to poor quality control, administrative errors and lack of supervision and training of staff. Médecins Sans Frontières discovered in 2004 that HIV negative individuals were enrolled in some HIV programmes. This paper describes the result of an audit of three sites to review testing practices, implement improved testing algorithms and offer re-testing to clients enrolled in the HIV clinic. In the Democratic Republic of Congo (DRC), Burundi and Ethiopia patients were identified for HIV retesting. In total, 44 false-positive patients were identified in HIV programmes in DRC, two in Burundi and seven in Ethiopia. Some of those identified had been abandoned by partners or started on anti-retroviral therapy or prophylaxis. Despite potential damage to programme reputations, no impact in terms of testing uptake occurred with mean monthly testing volumes stable after introduction of re-testing. In order to prevent the problem, training, supervision and quality control of testing procedures were strengthened. A simple and feasible confirmation test was added to the test algorithm. Prevalence of false positives after introducing the changes varied from zero percent (95% CI 0%-8.2%) to 10.3 percent (95% CI: 7.2%-14.1%) in Burundi and DRC respectively. False HIV diagnoses were found in a variety of programme settings and had devastating individual consequences. We re-tested individuals in our programmes while instituting improved testing procedures without a negative impact on test uptake. Considering the importance of correct diagnosis to the individual, as well as the resources needed to care for someone with HIV, it is critical to ensure that all patients registered in HIV programmes are accurately diagnosed.

The HIV negative partner in a HIV serodiscordant relationship is at high risk of becoming HIV infected. The annual risk of HIV infection for a partner of a person with HIV is about 10%, with higher annual transmission rates of 20-25% per year reported in Rwanda and Zambia. Although there is considerable variation across countries, recent studies in southern and east Africa countries with mature epidemics reported that up to two-thirds of infected persons in stable relationship are discordant. HIV serodiscordance is thus a recognized priority for HIV prevention intervention. In Nigeria only few studies have studied the burden of serodiscordance, making planning difficult. In this study HIV serodiscordance rate and associated factors among pregnant women were assessed in a large PMTCT clinic in Lagos Nigeria over a 9 years period. Information on HIV status disclosure, partners HIV status (confirmed by HIV test results), sociodemographic characteristics and reproductive information were obtained from the women after enrollment and entered into the case file. In the study, relevant information was managed with SPSS for windows version 19.0. The variables independently associated with HIV status discordance were determined in both univariate and multivariate analysis. P values and Odd ratio with their confidence intervals were calculated. Out of the 4435 women enrolled during the study period, 3712 (83.7%) had disclosed their status to their partner. Partner's HIV status among the women with confirmed HIV status was negative in 2065 (66.8%) women, thus a discordant rate of 66.8%. HIV status disclosure rate was 83.7%; with significantly higher disclosure rate in concordant couple (83.3%) compared to 76.8% among women in serodiscordant relationship (p = 0.00; OR: 1.5; 95% CI: 1.25-1.82). Discordant HIV status in a female positive relationship was found to be associated with history of at least two termination of pregnancy (OR: 3.05; 95% CI: 2.91-3.89) and five or more

Challenges of relational coping are well documented in the literature on couples and chronic illnesses, but there is significantly less research on the psychological aspects of couple relationships and HIV, particularly in international contexts. Coping with the uncertainty of illness progression, family planning, disclosure to friends and family, social isolation and stigma, fear of transmission, sexual intimacy, changes to social and physical functioning, and receiving and providing care pose special challenges for couples with discordant HIV statuses. This study examined the correlates of relationship satisfaction in Ugandan HIV-positive individuals seeking treatment at a community clinic. Relationship satisfaction of HIV-positive individuals was uniquely predicted by their couple identity and depression, underscoring the importance of mental and relational health in HIV/AIDS.

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

Advances in the treatment of HIV have resulted in a large growing population of older adults with HIV. These aging adults face added social, psychological, and physical challenges associated with the aging process. Correlations between depression, loneliness, health, and HIV/AIDS-related stigma have been studied, but there is little evaluation of these associations among HIV-positive adults over the age of 50. Data for these analyses were taken from the Research on Older Adults with HIV study of 914 New York City-based HIV-positive men and women over the age of 50. In total, 39.1% of participants exhibited symptoms of major depression (CES-D > 23). Multivariate modeling successfully explained 42% of the variance in depression which was significantly related to increased HIV-associated stigma, increased loneliness, decreased cognitive functioning, reduced levels of energy, and being younger. These data underscore the need for service providers and researchers to assert more aggressive and innovative efforts to resolve both psychosocial and physical health issues that characterize the graying of the AIDS epidemic in the USA. Data suggest that focusing efforts to reduce HIV-related stigma and loneliness may have lasting effects in reducing major depressive symptoms and improving perceived health.

Macrophages are a target of human immunodeficiency virus type 1 (HIV-1) infection and may serve as an important reservoir of the virus in the body, particularly after depletion of CD4+ T cells in HIV/AIDS. Recently, sterile alpha motif and histidine/aspartic acid domain-containing protein 1 (SAMHD1) was identified as the major restriction factor of HIV-1 infection in myeloid cells. SAMHD1 is targeted for proteolytic degradation by Vpx, a viral protein encoded by HIV-2 and many simian immunodeficiency viruses but not HIV-1. In this study, we assessed SAMHD1 restriction in in vitro differentiated macrophages and in freshly isolated macrophages from the lungs, abdomen, and brain. We found that infection and spread in in vitro cultured monocyte-derived macrophages were highly limited and that Vpx largely relieved the restriction to initial infection, as expected. We observed nearly identical infection and restriction profiles in freshly isolated peripheral blood monocytes, as well as lung (alveolar) and abdominal (peritoneal) macrophages. In contrast, under the same infection conditions, primary brain macrophages (microglia) were highly susceptible to HIV-1 infection despite levels of endogenous SAMHD1 comparable to the other macrophage populations. Addition of Vpx further increased HIV-1 infection under conditions of limiting virus input, and viral spread was robust whether or not SAMHD1 was depleted. These results suggest that HIV-1 infection of peripherally circulating macrophages is effectively restricted by SAMHD1; however, microglia are highly susceptible to infection despite SAMHD1 expression. These data may explain the long-standing observation that HIV-1 infection is often detected in macrophages in the brain, but seldom in other tissues of the body.

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

In 2002 MTV launched a global multicomponent HIV prevention campaign, "Staying Alive," reaching over 166 countries worldwide. An evaluation of this campaign focused on three diverse sites: Kathmandu, Nepal; São Paulo, Brazil; and Dakar, Senegal. Data were collected before and after campaign implementation through population-based household surveys. Using linear regression techniques, our evaluation examined the effects of campaign exposure on interpersonal communication about HIV and the effects of campaign exposure and interpersonal communication on beliefs about HIV prevention. We found a consistent positive effect of exposure on interpersonal communication across all sites, though there were differences among sites with regard to whom the respondent talked about HIV. We also found a consistent positive effect of exposure on HIV prevention beliefs across sites when interpersonal communication was simultaneously entered into the model. Finally, in two sites we found a relationship between interpersonal communication and HIV prevention beliefs, controlling for exposure, though again, the effects differed by the type of person the communication was with. These similar findings in three diverse sites provide ecological validity of the findings that "Staying Alive" promoted interpersonal communication and influenced young people's beliefs about HIV prevention in a positive way, evidence for the potential of a global media campaign to have an impact on social norms.

Young women with HIV and histories of physical and/or sexual abuse in childhood may be vulnerable to difficulties with disclosure to sexual partners. Abuse in childhood is highly prevalent in HIV-positive women, and has been associated with poorer communication, low assertiveness, low self worth, and increased risk for sexual and other risk behaviors that increase the risk of secondary transmission of HIV. HIV disclosure may be an important link between abuse and sexual risk behaviors. Qualitative interviews with 40 HIV-positive young women with childhood physical and/or sexual abuse were conducted; some women had also experienced adult victimization. Results suggest that HIV-positive women with abuse histories use a host of strategies to deal with disclosure of HIV status, including delaying disclosure, assessing hypothetical responses of partners, and determining appropriate stages in a relationship to disclose. Stigma was an important theme related to disclosure. We discuss how these disclosure processes impact sexual behavior and relationships and discuss intervention opportunities based on our findings.

This study examines the relationship between alcohol use, HIV status, and condom use among female sex workers in Nagaland, India. We analyzed data from a cross-sectional survey undertaken in 2009, using descriptive and multivariate statistics. Out of 417 female sex workers, one-fifth used alcohol daily and one-tenth were HIV-positive. HIV-positive female sex workers were more likely than HIV-negative female sex workers to consume alcohol daily (30.2% vs. 18.0%). HIV-positive daily alcohol users reported lower condom use at last sex with regular clients compared to HIV-positive non-daily alcohol users (46.2% vs. 79.3%), a relationship not evident among HIV-negative female sex workers. There is a need to promote awareness of synergies between alcohol use and HIV, and to screen for problematic alcohol use among female sex workers in order to reduce the spread of HIV.

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

Commentary on the potential impact of HIV-specific disclosure laws on persons living with HIV has been critical, plentiful, and enduring. Yet empirical information with which to answer even the most basic questions about these laws, such as whether HIV-positive persons living in a state with a disclosure law are aware of the law, is absent. This study reports on data gathered from a statewide sample of 384 HIV-positive persons living in a state with an HIV disclosure law. Participant awareness and understanding of the law were assessed. Data on the sources from which participants received information on the law and the perceived helpfulness of these sources were also collected. Analyses were conducted to identify associations between participant awareness or understanding of the law and demographic characteristics of participants or information sources encountered. The majority of participants were aware that their state had enacted an HIV-specific disclosure law. Understanding of the law was good, although there was substantial confusion over several provisions. The most prevalent and most helpful sources of information on the law were AIDS-related resources as opposed to mass media. Forty-two percent of the participants learned about the law when first diagnosed with HIV. Sixty-two percent of the participants reported that their case manager had told them about the law.

To assess completed wound healing after medical male circumcision (MMC) among human immunodeficiency virus (HIV)-negative and HIV-positive men with cluster of differentiation 4 (CD4) counts of HIV-positive men with low CD4 counts. In all, 262 HIV-negative and 177 HIV-positive consenting males aged ≥12 years accepted MMC using the dorsal slit procedure and were enrolled in the study. Socio-demographic and behavioural data and blood for HIV testing and CD4 counts were collected at baseline. Participants were followed weekly to collect information on resumption of sex, condom use and both self-reported and clinically assessed wound healing. The proportions healed among HIV-positive men were compared with HIV-negative men. Time to complete wound healing was assessed by Kaplan-Meier survival analysis. There were no statistically significant differences in the proportion of men healed by HIV status. At 4 weeks, the proportions healed were 85.9% in HIV-negative men, 77.4% in HIV-positive men with a CD4 count of ≥350 cells/mm(3) and 87.1% in HIV-positive men with a CD4 count of healing was 4 weeks and did not vary by HIV or CD4 status. All men had certified complete wound healing at 6 weeks after MMC. In all, 1.4% of HIV-positive men with a CD4 count of healing, compared with 8.5% among HIV-positive men with a CD4 count of ≥350 cells/mm(3) (P = 0.052) and 7.8% (P = 0.081) among HIV-negative men. Inclusion of HIV-positive men with low CD4 counts in MMC services is not deleterious to postoperative wound healing. © 2013 The Authors. BJU International © 2013 BJU International.
Full Text Available Globally, suicide and HIV/AIDS remain two of the greatest healthcare issues, particularly in low- and middle-income countries. Several studies have observed a relationship between suicidal behaviour and HIV/AIDS. Materials and Methods. The main objective of this research was to determine the prevalence of elevated risk of suicidal ideation in HIV-positive persons immediately following voluntary HIV counselling and testing (VCT. The study sample consisted of adult volunteers attending the VCT clinic at a university-affiliated, general state hospital. Participants completed a sociodemographic questionnaire, Beck’s Hopeless Scale, and Beck’s Depression Inventory. Results. A significantly elevated risk of suicidal ideation was found in 83.1% of the patients who tested seropositive. Despite a wide age range in the cohort studied, the majority of patients with suicidal ideation were males in the younger age group (age < 30 years, consistent with the age-related spread of the disease and an increase in suicidal behaviour in younger people. Relevant associated variables are discussed. Conclusion. The results serve as important markers that could alert healthcare professionals to underlying suicide risks in HIV-positive patients. It is recommended that screening for elevated risk of suicidal ideation and prevention of suicidal behaviour should form a routine aspect of comprehensive patient care at VCT clinics.

Epidermodysplasia verruciformis (EV) is a rare dermatological manifestation of the human papillomavirus (HPV) infection, which causes distinctive skin lesions in sun-exposed areas. Both inherited and acquired forms exist. Immunocompromised individuals, such as HIV patients, are at risk of acquired EV. EV poses challenges in its management and variable responses are seen in different individuals. In addition, EV carries a significant risk of skin malignancy with certain HPV types that require skin surveillance. A case of acquired EV in a HIV-positive patient is presented in this report. © The Author(s) 2016.
The 8th U.S. Circuit Court of Appeals in Missouri dismissed claims by prison inmate [name removed] that special HIV housing units automatically reveal his serostatus to other inmates and corrections officers. The court cited precedents that inmates had little expectation of privacy and that segregating HIV-positive inmates served a legitimate government interest. The 8th Circuit Court endorsement of 3 precedents brings the total number of States that allow prisoner segregation to 15. The 8th Circuit Court rejected the inmate's claims that his confinement violated his Eighth Amendment right to be free of cruel and unusual punishment.

A positioning technique for an endovascular microdevice propelled by magnetic force inside a magnetic resonance imaging (MRI) system is being developed. Positioning options are presented and a magnetic positioning technique is described in more details. Since a magnetic positioning system is deeply dependent on the quality of the measurement modality, we describe the main magnetic field measurement techniques that can be used inside an MRI. Finally, we propose a magnetic positioning system using MRI phase images to measure the magnetic distortion induced by the ferromagnetic body. Positioning results on a 1010/1020 carbon steel, 1.5875 mm diameter sphere with gradient echo phase images are presented.

Full Text Available Objective: To evaluate the neurological complications among Iranian HIV-positive patients. Methods: This cross-sectional study was conducted among 428 patients diagnosed with HIV infection between 2006 and 2009 at Imam Khomeini hospital, Tehran, Iran. Demographic and clinical variables as well as laboratory tests were extracted and analyzed. Also, another 100 patients refereed to Voluntary Counseling and Testing center of the hospital were visited and evaluated for neurological complications. Results: Among the patients, neurologic manifestations were observed in 34 (7.94% patients. Twenty three percent of the patients received antiretroviral therapy. Identified causes included brain toxoplasmosis (14.7%, progressive multi-focal leuko encephalopathy (5.9%, HIV encephalopathy (5.9%, TB meningitis (5% and unknown etiologies (11.8%. Also, among 100 patients who were admitted and visited at the Voluntary Counseling and Testing center, no one was diagnosed for any neurological manifestations. Conclusions: According to our results, toxoplasmosis is the most frequent cause of neurological conditions among Iranian HIV infected patients and should be considered in any HIV/AIDS patient with neurological manifestations.
Full Text Available HIV-positive women have an increased risk of invasive cervical cancer but cytologic screening is effective in reducing incidence. Little is known about cervical screening coverage or the prevalence of abnormal cytology among HIV-positive women in Ukraine, which has the most severe HIV epidemic in Europe.Poisson regression models were fitted to data from 1120 women enrolled at three sites of the Ukraine Cohort Study of HIV-infected Childbearing Women to investigate factors associated with receiving cervical screening as part of HIV care. All women had been diagnosed as HIV-positive before or during their most recent pregnancy. Prevalence of cervical abnormalities (high/low grade squamous intraepithelial lesions among women who had been screened was estimated, and associated factors explored.Overall, 30% (337/1120 of women had received a cervical screening test as part of HIV care at study enrolment (median 10 months postpartum, a third (115/334 of whom had been tested >12 months previously.

Introduction HIV-positive women have an increased risk of invasive cervical cancer but cytologic screening is effective in reducing incidence. Little is known about cervical screening coverage or the prevalence of abnormal cytology among HIV-positive women in Ukraine, which has the most severe HIV epidemic in Europe. Methods Poisson regression models were fitted to data from 1120 women enrolled at three sites of the Ukraine Cohort Study of HIV-infected Childbearing Women to investigate factors associated with receiving cervical screening as part of HIV care. All women had been diagnosed as HIV-positive before or during their most recent pregnancy. Prevalence of cervical abnormalities (high/low grade squamous intraepithelial lesions) among women who had been screened was estimated, and associated factors explored. Results Overall, 30% (337/1120) of women had received a cervical screening test as part of HIV care at study enrolment (median 10 months postpartum), a third (115/334) of whom had been tested >12 months previously. In adjusted analyses, women diagnosed as HIV-positive during (vs before) their most recent pregnancy were significantly less likely to have a screening test reported, on adjusting for other potential risk factors (adjusted prevalence ratio (APR) 0.62, 95% CI 0.51–0.75 p<0.01 for 1st/2nd trimester diagnosis and APR 0.42, 95% CI 0.28–0.63 p<0.01 for 3rd trimester/intrapartum diagnosis). Among those with a cervical screening result reported at any time (including follow-up), 21% (68/325) had a finding of cervical abnormality. In adjusted analyses, Herpes simplex virus 2 seropositivity and a recent diagnosis of bacterial vaginosis were associated with an increased risk of abnormal cervical cytology (APR 1.83 95% CI 1.07–3.11 and APR 3.49 95% CI 2.11–5.76 respectively). Conclusions In this high risk population, cervical screening coverage as part of HIV care was low and could be improved by an organised cervical screening programme for HIV-positive

The aim of the study was to assess pregnancy complications in HIV-positive women and changes in the rates of such complications over 11 years in the Frankfurt HIV Cohort. There were 330 pregnancies in HIV-positive women between 1 January 2002 and 31 December 2012. The rate of pregnancy-related complications, such as gestational diabetes mellitus (GDM), pre-eclampsia and preterm delivery, the mode of delivery and obstetric history were analysed. Maternal and neonatal morbidity/mortality as well as HIV mother-to-child transmission (MTCT) were evaluated. In our cohort, GDM was diagnosed in 38 of 330 women (11.4%). Five women (1.5%) developed pre-eclamspia or hypertension. In 16 women (4.8%), premature rupture of membranes (PROM) occurred and 46 women (13.7%) were admitted with preterm contractions. The preterm delivery rate was 36.5% (n = 122), and 26.9% of deliveries (n = 90) were between 34+0 and 36+6 weeks of gestation. Over the observation period, the percentage of women with undetectable HIV viral load (VL) increased significantly (P HIV Association.

It is estimated that over 90% of children infected with human immunodeficiency virus (HIV) live in the developing world and particularly in sub-Saharan Africa. Pulmonary disease is the most common clinical feature of acquired immunodeficiency syndrome (AIDS) in infants and children causing the most morbidity and mortality, and is the primary cause of death in 50% of cases. Children with lung disease are surviving progressively longer because of earlier diagnosis and antiretroviral treatment and, therefore, thoracic manifestations have continued to change and unexpected complications are being encountered. It has been reported that 33% of HIV-positive children have chronic changes on chest radiographs by the age of 4 years. Lymphocytic interstitial pneumonitis is common in the paediatric HIV population and is responsible for 30-40% of pulmonary disease. HIV-positive children also have a higher incidence of pulmonary malignancies, including lymphoma and pulmonary Kaposi sarcoma. Immune reconstitution inflammatory syndrome is seen after highly active antiretroviral treatment. Complications of pulmonary infections, aspiration and rarely interstitial pneumonitis are also seen. This review focuses on the imaging findings of non-infective chronic pulmonary disease. (orig.)
Full Text Available Background and aim: An opportunist infection in patients diagnosed with human immunodeficiency virus (HIV is the Epstein-Barr virus (EBV which causes serious complications. This study is conducted to examine the frequency of EBV in HIV/AIDS sufferers and compare it with non-sufferers and examine its correlation with the number of CD4+ lymphocytes. Methods: In a case-control, prospective study, two 114-member groups (patients with and without human immunodeficiency virus of equal sex and age – one group suffering from HIV – were assessed for the presence of IgG antibody against EBV capsid virus and the number of CD4+ lymphocytes and the results were analyzed based on the objectives of the study. Results: A total of 103 (90.4% of HIV-positives and 37 (32.5% of control group were tested positive for EBV-VCA IgG (p value = 0.001. The amount of antibody and the number of CD4+ lymphocytes were in a meaningful and reverse relationship (p value = 0.0003. There was no meaningless difference between the presence of EBV-VCA IgG antibody and the age and sex of patients, transmission of virus and receiving HAART anti-virus treatment (p value>0.05 Conclusion: Due to complications of acute EBV virus and its high frequency in HIV patients, these patients are strongly recommended to be examined for EBV infection after diagnosis in a bid to prevent more mortality and morbidity. Preventive actions and periodical checkups must be done for EBV-positives.
Full Text Available There is a recognized gap in the evidence base relating to the nature and components of interventions to address the psycho-social needs of HIV positive young people. We used mixed methods research to strengthen a community support group intervention for HIV positive young people based in Harare, Zimbabwe.A quantitative questionnaire was administered to HIV positive Africaid support group attendees. Afterwards, qualitative data were collected from young people aged 15-18 through tape-recorded in-depth interviews (n=10, 3 focus group discussions (FGDs and 16 life history narratives. Data were also collected from caregivers, health care workers, and community members through FGDs (n=6 groups and in-depth interviews (n=12. Quantitative data were processed and analysed using STATA 10. Qualitative data were analysed using thematic analysis.229/310 young people completed the quantitative questionnaire (74% participation. Median age was 14 (range 6-18 years; 59% were female. Self-reported adherence to antiretrovirals was sub-optimal. Psychological well being was poor (median score on Shona Symptom Questionnaire 9/14; 63% were at risk of depression. Qualitative findings suggested that challenges faced by positive children include verbal abuse, stigma, and discrimination. While data showed that support group attendance is helpful, young people stressed that life outside the confines of the group was more challenging. Caregivers felt ill-equipped to support the children in their care. These data, combined with a previously validated conceptual framework for family-centred interventions, were used to guide the development of the existing programme of adolescent support groups into a more comprehensive evidence-based psychosocial support programme encompassing caregiver and household members.This study allowed us to describe the lived experiences of HIV positive young people and their caregivers in Zimbabwe. The findings contributed to the enhancement of
Full Text Available Objective: As a first study, suicidal ideation and its correlates have been evaluated in Iranian HIV positive population . Methods:One hundred and fifty HIV-positive individuals were recruited in this cross-sectional study. The Hospital Anxiety and Depression Scale (HADS, Positive and Negative Suicide Ideation (PANSI, Pittsburgh Sleep Quality Inventory (PSQI and Somatization subscale of Symptom Checklist 90 (SCL 90 as self- reported questionnaires were used to assess the patients’ anxiety and depression status, suicidal thoughts, sleep quality and physiological factors, respectively . Results:Antiretroviral therapy and efavirenz intake did not show any significant effects on the patients’ suicidal ideation. Anxiety (p<0.001, depression (p<0.001, poor physical activity (P<0.001 and sleep quality (p<0.001 were significantly associated with the patients’ negative suicidal ideation. From the patients’ demographic data, unemployment (p = 0.04, living alone (p = 0.01, and lack of family support (p = 0.01 were correlated with the patients’ negative suicidal thoughts . Conclusion:Although hospitals are the main referral centers for providing care for HIV-positive individuals in Tehran, Iran, conducting a multi-center study with sufficient sample size from different areas of our country that include individuals with different behaviors and cultures is essential to confirm the results of this study.

An unacceptably high frequency of false positive HIV test results has been reported in various settings. Given the severity and implications of an HIV+ diagnosis, a false positive result is likely to be psychologically traumatic and may result in inappropriate and potentially harmful treatment. The current HIV testing algorithm being used in Zimbabwe does not include repeat testing for HIV positive results, and it is not currently known whether testing errors are leading to false positive dia...

The study aimed to describe the seroprevalence of hepatitis A virus (HAV) in HIV-positive adult patients in Taiwan between 2012 and 2016 and to examine the evolution of HAV seroprevalence between 2004-2007 and 2012-2016. Clinical information and data of anti-HAV antibody results were collected from 2,860 antiretroviral-naïve HIV-positive Taiwanese aged 18 years or older who initiated combination antiretroviral therapy at 11 hospitals around Taiwan between 2012 and 2016 (2012-2016 cohort). A multivariate logistic regression model was applied to identify independent variables associated with HAV seropositivity. Comparisons of HAV seroprevalences and associated clinical characteristics were made between this 2012-2016 cohort and a previous cohort of 1580 HIV-positive patients in 2004-2007 (2004-2007 cohort). Of the 2,860 HIV-positive patients between 2012 and 2016, the overall HAV seropositivity rate was 21.2% (605/2860), which was independently associated with an older age (adjusted odds ratio [AOR], per 1-year increase, 1.13; 95% confidence interval [95% CI], 1.11-1.15) and co-infection with hepatitis B virus (AOR 1.44; 95% CI, 1.08-1.93). Residence in southern Taiwan (AOR 0.49; 95% CI, 0.34-0.72) was inversely associated with HAV seropositivity. The overall HAV seroprevalence in the 2012-2016 cohort was significantly lower than that in the 2004-2007 cohort (21.2% vs 60.9%, p<0.01). The decreases of HAV seropositivity rate were observed in nearly every age-matched group, which suggested the cohort effect on HAV seroepidemiology. However, among individuals aged 25 years or younger, the HAV seropositivity rate increased from 3.8% (2/52) in the 2004-2007 cohort to 8.5% (50/587) in the 2012-2016 cohort, with 95.4% (560/587) being MSM in this age group of the latter cohort. HAV seroprevalence has decreased with time among HIV-positive adults in Taiwan. The cohort effect has increased the number of young HIV-positive patients that are susceptible to HAV infection in a

Panic disorder (PD) occurs at greater rates among those with HIV compared to those without HIV. Rates of PD may be elevated among those with opioid dependence (persons who inject drugs, PWID). Persons with HIV experience common bodily symptoms as a result of the disease and these symptoms overlap with those of PD which may contribute to a “fear of fear” cycle present in PD. HIV-positive, PWID represent an at-risk population in terms of poor medication adherence. HIV symptoms and HIV medicatio...

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

Tuberculosis (TB) is the most common opportunistic infection and the leading cause of death in HIV-positive people worldwide. Diagnosing TB is difficult, and is more challenging in resource-scarce settings where culture-based diagnostic methods rely on poorly sensitive smear microscopy by Ziehl-Neelsen stain (ZN). We performed a cross-sectional study examining the diagnostic utility of Microscopic Observation Drug Susceptibility liquid culture (MODS) versus traditional Ziehl-Neelsen staining (ZN) and Lowenstein Jensen culture (LJ) of pulmonary tuberculosis (TB) and multidrug-resistant tuberculosis (MDRTB) in HIV-infected patients in Bolivia. For sputum scarce individuals we assessed the value of the string test and induced sputum for TB diagnosis. The presence of Mycobacterium tuberculosis (Mtb) in the sputum of 107 HIV-positive patients was evaluated by ZN, LJ, and MODS. Gastric secretion samples obtained by the string test were evaluated by MODS in 102 patients. The TB-HIV co-infection rate of HIV patients with respiratory symptoms by sputum sample was 45 % (48/107); 46/48 (96 %) were positive by MODS, 38/48 (79 %) by LJ, and 30/48 (63 %) by ZN. The rate of MDRTB was 9 % (4/48). Median time to positive culture was 10 days by MODS versus 34 days by LJ (p Bolivia.

PI susceptibility results from a complex interplay between protease and Gag proteins, with Gag showing wide variation across HIV-1 subtypes. We explored the impact of pre-treatment susceptibility on the outcome of lopinavir/ritonavir monotherapy. Treatment-naive individuals who experienced lopinavir/ritonavir monotherapy failure from the MONARK study were matched (by subtype, viral load and baseline CD4 count) with those who achieved virological response ('successes'). Successes were defined by viral load protease was amplified from patient samples for in vitro phenotypic susceptibility testing, with susceptibility expressed as fold change (FC) relative to a subtype B reference strain. Baseline lopinavir susceptibility was lower in viral failures compared with viral successes, but the differences were not statistically significant (median lopinavir susceptibility: 4.4 versus 8.5, respectively, P = 0.17). Among CRF02_AG/G patients, there was a significant difference in lopinavir susceptibility between the two groups (7.1 versus 10.4, P = 0.047), while in subtype B the difference was not significant (2.7 versus 3.4, P = 0.13). Subtype CRF02_AG/G viruses had a median lopinavir FC of 8.7 compared with 3.1 for subtype B (P = 0.001). We report an association between reduced PI susceptibility (using full-length Gag-protease sequences) at baseline and subsequent virological failure on lopinavir/ritonavir monotherapy in antiretroviral-naive patients harbouring subtype CRF02_AG/G viruses. We speculate that this may be important in the context of suboptimal adherence in determining viral failure. © The Author 2014.

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

To explore whether the prevalence and determinants of insufficient work ability (WA) of older HIV-positive workers differ from a comparable group of HIV-negative workers. Cross-sectional data from 359 HIV-negative and 264 HIV-positive middle-aged individuals (45-65 years) participating in paid labor, collected within the AGEhIV Cohort Study between October 2010-September 2012, were selected. Data were collected by self-administered questionnaires and physical examination. Participants self-rated their current WA, ranging from 0 to 10. WA was dichotomized into insufficient (HIV status on insufficient WA and determinants of insufficient WA. Overall, 8% of participants reported insufficient WA (HIV-positive 9 vs. HIV-negative 7%, P = 0.20). Twice as many HIV-positive as HIV-negative individuals were declared partly unfit for work (6 vs. 3%, P = 0.02). HIV status itself was not associated with WA in univariable and multivariable analyses. Multivariable analyses revealed that low educational level, working fewer hours, being partly unfit for work, experiencing a high need for recovery after work, staying home from work ≥2 times in the past 6 months, and reporting depressive symptoms were associated with insufficient WA, independent of HIV status. HIV-positive individuals aged 45-65 years participating in paid labor seem to function as well at work as HIV-negative individuals. HIV-positive participants were more often formally declared partly unfit for work, but percentages were low in both groups. Knowledge of determinants of insufficient WA may help employers and professionals to optimize WA.

The use of medicinal herbs whose efficacy and toxicities are not known by HIV-positive people in Lesotho is a threat to the effectiveness of antiretroviral treatment. This study explored some medicinal herbs used by HIV-positive people in Lesotho and the reasons for their use. This was a cross sectional study based on a questionnaire distributed to purposively-sampled HIV-positive people in Leribe and Maseru districts of Lesotho. The participants' socio-demographic and clinical variables were summarized using frequency tables in Stata version 13 statistical software. Data variables for medicinal herbs used, frequency of use, uses by the participants and in the literature, parts of plants used and the method of preparation were also explored. Out of 400 questionnaires distributed to the participants, 389 were returned with data acceptable for analysis. Ages of the participants ranged from 18 to 75 years (Mean=43 + 11.6). Out of the 272 (69.9%) participants who conceded that they had used medicinal herbs at least once, 30 (7.7%) participants used medicinal herbs frequently while 242 (62.2 %) rarely used the herbs. At least 20 plant species belonging to 16 families were reportedly used by the participants. Asteraceae was the most common plant family reportedly used by the participants. Allium sativum and Dicoma anomala, reportedly used by 21.0% and 14.3% respectively, were the most commonly used medicinal herbs in this population. In addition, boosting the immune system and treating gastrointestinal ailments, apparently cited by 32% and 28% participants respectively, were the most commonly reported reasons for using medicinal herbs. A considerable proportion (69.9%) of HIV-positive people use medicinal herbs in this population, and 7.7% use them frequently. At least 20 plant species belonging to 16 families were reportedly used by the participants. HIV counselling protocols in Lesotho should emphasize the dangers of using medicinal herbs whose safety and compatibility

Full Text Available The objective of this study was to assess consumer acceptability, preference and consumption intent of an instant soy maize porridge, compared to an instant plain maize porridge, in order to determine the successful inclusion of the soy maize porridge as a food supplement for HIV subjects in a subsequent nutrition intervention trial, to improve their nutritional status. A 5-point hedonic and food action rating scale was used for this purpose. HIV-positive (n=57 and HIV-negative (n=47 subjects were recruited on a basis of availability and willingness to participate. Long-term acceptability and compliance of HIV-positive consumers (n=9 was assessed after three and five months. Analysis of variance (ANOVA, Tukey’s multiple comparison test and T-tests (p≤0.05 were performed. Overall, consumers found the soy maize porridge significantly more acceptable, preferred it to, and also intended to consume it more often than the plain maize porridge. There were no significant differences between the HIV-positive and HIV-negative group regarding acceptability, preference and consumption intent. After three and five months, the HIV-positive consumers (n=9 did not find acceptability of the soy maize porridge significantly different from the first evaluation. It therefore had the potential to be included successfully in the nutrition intervention trial. The current study emphasises the need for sensory evaluation of food products prior to including them in intervention studies, to assess consumers’ acceptance of them.

Full Text Available BACKGROUND: Several studies have implicated a recently discovered gammaretrovirus, XMRV (Xenotropic murine leukaemia virus-related virus, in chronic fatigue syndrome and prostate cancer, though whether as causative agent or opportunistic infection is unclear. It has also been suggested that the virus can be found circulating amongst the general population. The discovery has been controversial, with conflicting results from attempts to reproduce the original studies. METHODOLOGY/PRINCIPAL FINDINGS: We extracted peripheral blood DNA from a cohort of 540 HIV-1-positive patients (approximately 20% of whom have never been on anti-retroviral treatment and determined the presence of XMRV and related viruses using TaqMan PCR. While we were able to amplify as few as 5 copies of positive control DNA, we did not find any positive samples in the patient cohort. CONCLUSIONS/SIGNIFICANCE: In view of these negative findings in this highly susceptible group, we conclude that it is unlikely that XMRV or related viruses are circulating at a significant level, if at all, in HIV-1-positive patients in London or in the general population.

HIV positive individuals are prone to malnutrition due to inadequate dietary intake. Additionally, in low-income countries, including Nigeria, stigmatization and discrimination result in a lack of support for HIV-positive individuals ultimately contributing to even further reduced food availability and inadequate dietary intake. This study aimed to determine the nutrirional status of HIV-positive individuals on free, highly active antiretroviral therapy (HAART) in Abakaliki, southeast Nigeria. Subjective global assessment (SGA) technique was used to survey the nutritional status of 120 HIV-positive individuals and a control group over a one-year period. All the HIV-positive individuals and their control group were physically active, with a third of them belonging to the lower socioeconomic status. There were significantly more malnourished individuals among the HIV-positive group than in the control group (P HIV-positive patients in southeast Nigeria.

Full Text Available BACKGROUND AND PURPOSE: Asymptomatic central nervous system (CNS involvement occurs in the early stage of the human immunodeficiency virus (HIV infection. It has been documented that the hepatitis C virus (HCV can replicate in the CNS. The aim of the study was to evaluate early disturbances in cerebral microcirculation using magnetic resonance (MR perfusion-weighted imaging (PWI in asymptomatic HIV-1-positive and HCV-positive patients, as well as to assess the correlation between PWI measurements and the clinical data. MATERIALS AND METHODS: Fifty-six patients: 17 HIV-1-positive non-treated, 18 HIV-1-positive treated with combination antiretroviral therapy (cART, 7 HIV-1/HCV-positive non-treated, 14 HCV-positive before antiviral therapy and 18 control subjects were enrolled in the study. PWI was performed with a 1.5T MR unit using dynamic susceptibility contrast (DSC method. Cerebral blood volume (CBV measurements relative to cerebellum (rCBV were evaluated in the posterior cingulated region (PCG, basal ganglia (BG, temporoparietal (TPC and frontal cortices (FC, as well as in white matter of frontoparietal areas. Correlations of rCBV values with immunologic data and liver histology activity index (HAI were analyzed.

The HIV infection of a family member can impact family quality of life (FQoL). The objectives of this study are to (1) describe patterns of FQoL among mothers living with HIV (MLHIV) and (2) identify key factors associated with FQoL in families affected by HIV. Recruitment took place in HIV-specialized clinics and community organizations. A 100 MLHIV and 67 of their children participated in this study. Mothers were on average 40.8 years old and reported having an average of two dependent children at home (M = 2.1, SD = 1.0). Participating children were 16.2 years old, on average. Half of the children were boys (50.8%). More than half were aware of their mother's positive HIV status (68.2%) and 19.7% were diagnosed with HIV. All HIV-positive children were aware of their status. A latent profile analysis was performed on the five continuous indicators of FQoL, and three main profiles of self-reported FQoL among MLHIV were established: high FQoL (33%), moderate FQoL (58%), and low FQoL (9%). Among the mothers' characteristics, education, physical functioning, social support, and resilience increased FQoL, while anxiety and irritability decreased FQoL. Among the children's characteristics, resilience followed the FQoL profile. A trend was observed toward children's greater awareness of the mother's HIV status in high and low FQoL profiles. Additionally, irritability tended to be higher within the lower FQoL profile. FQoL profiles can be used to identify families needing special care, particularly for family interventions with both parents and children. Other relevant indicators must be studied (e.g., closeness and support between family members, availability and accessibility of care, family structure, father-child relationships, and medical condition of the mother) and longitudinal research conducted to estimate the direction of causality between FQoL profile and individual family member characteristics.

HIV positive patients can suffer many complications due to infectious diseases. A sever drug reaction to some of the drugs involved in the treatment can overlap the symptoms of the infections, making the diagnosis very difficult. We present the case of a 28-year-old-man, HIV positive, with secondary syphilis, who developed a Stevens Johnson Syndrome (SJS) caused by one of the many drugs he received. The SJS was overlapped with a possible Jarisch Herxheimer Reaction, which complicated the diagnosis of the skin reaction. In HIV+ patients, the overlapping of severe drug reactions and infectious diseases could be fatal, thus an accurate diagnosis is mandatory. A Rapid Plasma Reagin Test (RPR), an ELISA test, a blood laboratory test, chest radiography and a skin biopsy were realized in order to diagnose the infectious disease and the cause of skin lesions. Intradermal tests and double blind challenge tests were realized in the allergy study. The laboratory tests confirmed the diagnosis of syphilis; the skin biopsy confirmed the cause of lesions, a severe allergic reaction as a SJS. The allergy study discharged all the drugs involved, except dypirone which wasn't proved in the study because of the severity of reaction, the high possibility to be the causative drug and the alternative of other similar drugs available. For the inflammatory response, HIV+ patients are especially susceptible to severe reaction, both infectious and allergic, as in this case. Thus, recent patents emphasize the interest in inflammatory molecules that cause inflammatory symptoms. Although the diagnose of SJS has established criteria, the possibility of overlapping with infectious illness and/or with its treatment, may complicate the diagnosis.

HIV-positive men are living long and healthier lives while managing HIV as a chronic illness. Although research has extensively documented the experiences of illness of people living with HIV, dating, marriage, and fatherhood among heterosexual Latino men has not been examined. To address this gap, this study used a qualitative study design to examine patterns and strategies for dating, marriage, and parenthood among 24 HIV-positive heterosexual Puerto Rican men living in Boston. The findings in our study indicate that an HIV diagnosis does not necessarily deter men from having an active sexual life, marrying, or having children. In fact, for some of the men, engaging in these social and life-changing events is part of moving on and normalizing life with HIV; these men planned for, achieved, and interpreted these events in the context of establishing normalcy with HIV. Although the HIV diagnosis discouraged some men from engaging in sexual relations, getting married, or having children, others fulfilled these desires with strategies aimed to reconciling their HIV status in their personal life, including dating or marrying HIV-positive women only. Additional important themes identified in this study include the decision to disclose HIV status to new sexual partners as well as the decision to accept the risk of HIV transmission to a child or partner in order to fulfill desires of fatherhood. Understanding the personal struggles, decision-making patterns, and needs of HIV-positive heterosexual men can aid in designing interventions that support healthy living with HIV. © The Author(s) 2014.
treatment (HAART) and thereby restore immunity. Diagnosing HIV patients with active TB can be a challenge. To diagnose patients with active TB, the test should have high sensitivity, high specificity and be able to discriminate between active and latent TB. There are many studies assessing IGRA in HIV-positive...... individuals, and our learning curve is going up with new knowledge and circumstantial evidence. There is clearly an effect on the performance of the IGRA test when persons with active TB are co-infected with HIV. Studies looking at the performance of QFT-GIT in HIV-positive/negative TB patients show...... significantly lower positivity rates in HIV-positive patients. The clinical use of IGRA for the diagnosis of active TB in HIV-positives in high endemic regions may be limited for several reasons, and it is not always recommended to use IGRA in all cases of clinical suspicion. Arguments against using IGRA in HIV-positive...

A 36-year-old man presented for an HIV test, which answered positive. He gave a six-week history of headache and fever. His syphilis serology was also positive with a Venereal Disease Research Laboratory (VDRL) titre of 1:32, and positive Treponema pallidum particle agglutination (TPPA) assay and fluorescent treponemal antibody (FTA). When he attended for treatment of the syphilis, he had developed severe pain in both lower limbs. Plain radiographs were normal. An isotope bone scan showed multiple areas of increased uptake, consistent with syphilitic periostitis. Some of these lesions were asymptomatic. He was treated with benzathine penicillin and his pain resolved. The bone scan had normalized after six months. We review the previous literature regarding syphilitic bone pain and periostitis. We discuss the importance of considering syphilis in the differential diagnosis of any sexually active adult presenting with bone pain, and highlight the usefulness of isotope bone scans in clarifying the clinical picture.

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

To examine false-positive HIV DNA polymerase chain reaction (PCR) test results in children, and the potential implications for the paediatric HIV epidemic in sub-Saharan Africa. A review was done of records over a 6-year period of children less than 18 months old at an HIV treatment site in South Africa, to evaluate those with an initial 'false'-positive HIV DNA PCR result, but later proven to be HIV-uninfected with HIV DNA PCR and/or quantitative HIV RNA PCR tests. We calculated the influence of changing HIV transmission rates on predictive values (PV) of HIV DNA PCR tests in a hypothetical population of all HIV-exposed infants over a 1-year period. (Positive PV: proportion of individuals with a positive test with disease; negative PV: proportion of individuals with negative test and no disease). Of 718 children, 40 with an initial positive HIV DNA PCR test were subsequently proven to be HIV-uninfected, resulting in a positive PV of 94.4%. Most (75%) uninfected children had PMTCT interventions and were asymptomatic or mildly symptomatic (77.5%). Calculations using a test specificity of 99.4%, as reported previously, show a decrease in positive PV using a single-test strategy from 98.6% at 30% HIV transmission rate, to 94.8% at 10% transmission, to 62.5% at 1% transmission. Reduction in test specificity further decreases positive PV at low transmission rates. Decreasing mother-to-child HIV transmission rates reduce the positive predictive value of a single HIV DNA PCR test result, necessitating adaptations to diagnostic algorithms to avoid misdiagnosis and inappropriate treatment, especially with early initiation of antiretroviral therapy in asymptomatic infants.

This study was designed to investigate the prevalence of oral human papillomavirus (HPV) infection among HIV-positive and HIV-negative Thai men and women. Participants including men who have sex with men (MSM) and heterosexual women were enrolled at the Thai Red Cross Anonymous Clinic in Bangkok. History taking and oral examination were performed by three independent dentists after calibration. HPV infection was evaluated from oral rinse with mouthwash collected at the time of examination. HPV typing was performed by PCR and nucleic acid hybridization to detect thirty-seven HPV DNA genotypes using Linear Array(®) HPV Genotyping Test (Roche Molecular System, Inc.). 244 subjects were enrolled in the study, consisted of 187 HIV-positive (51.9% women and 48.1% MSM) and 57 HIV-negative (21.0% women and 79.0% MSM) Thai subjects. The prevalence of oral HPV infection was 17.2% in HIV-positive subjects whereas only 5.3% of HIV-negative cases had HPV detected in their oral rinses (p=0.0346). Among HIV positive subjects, MSM had higher chance of having HPV infection than females (25% vs. 9.4%, p=0.0074). HIV-positive Thai MSM and women had higher prevalence of oral HPV infection than those without HIV. Copyright © 2015 Elsevier Ltd. All rights reserved.

Immunoglobulin (Ig) GM and KM allotypes, genetic markers of γ and κ chains, are associated with humoral immune responsiveness. Previous studies have shown the relationships between GM6-carrying haplotypes and susceptibility to malaria infection in children and adults; however, the role of the genetic markers in placental malaria (PM) infection and PM with HIV co-infection during pregnancy has not been investigated. We examined the relationship between the gene polymorphisms of Ig GM6 and KM allotypes and the risk of PM infection in pregnant women with known HIV status. DNA samples from 728 pregnant women were genotyped for GM6 and KM alleles using polymerase chain reaction-restriction fragment length polymorphism method. Individual GM6 and KM genotypes and the combined GM6 and KM genotypes were assessed in relation to PM in HIV-1 negative and positive women, respectively. There was no significant effect of individual GM6 and KM genotypes on the risk of PM infection in HIV-1 negative and positive women. However, the combination of homozygosity for GM6(+) and KM3 was associated with decreased risk of PM (adjusted OR, 0.25; 95% CI, 0.08–0.8; P = 0.019) in HIV-1 negative women while in HIV-1 positive women the combination of GM6(+/−) with either KM1-3 or KM1 was associated with increased risk of PM infection (adjusted OR, 2.10; 95% CI, 1.18–3.73; P = 0.011). Hardy-Weinberg Equilibrium (HWE) tests further showed an overall significant positive F(is) (indication of deficit in heterozygotes) for GM6 while there was no deviation for KM genotype frequency from HWE in the same population. These findings suggest that the combination of homozygous GM6(+) and KM3 may protect against PM in HIV-1 negative women while the HIV-1 positive women with heterozygous GM6(+/−) combined with KM1-3 or KM1 may be more susceptible to PM infection. The deficit in heterozygotes for GM6 further suggests that GM6 could be under selection likely by malaria infection. PMID

Despite tremendous advances in our understanding of HIV/AIDS since the first cases were reported 30 years ago, we are still a long way from understanding critical steps of HIV acquisition, pathogenesis and correlates of protection. Our new understanding of the importance of the mucosa as a target for HIV infection, as well as our recent observations showing that altered expression and responses of innate pattern recognition receptors are significantly associated with pathogenesis and resistance to HIV infection, indicate that correlates of immunity to HIV are more likely to be associated with mucosal and innate responses. Most of the heterosexual encounters do not result in productive HIV infection, suggesting that the female genital tract is protected against HIV by innate defence molecules, such as antiproteases, secreted mucosally. The present review highlights the role and significance of the serine protease inhibitors SLPI (secretory leucocyte protease inhibitor), trappin-2, elafin and ps20 (prostate stromal protein 20 kDa) in HIV susceptibility and infection. Interestingly, in contrast with SLPI, trappin-2 and elafin, ps20 has been shown to enhance HIV infectivity. Thus understanding the balance and interaction of these factors in mucosal fluids may significantly influence HIV infection.

Saliva is a complex oral biologic fluid secreted by major and minor salivary glands. Saliva has immunological, enzymatic and antioxidant defense mechanisms. Infection with human immunodeficiency virus (HIV) is a life-threatening disease. The aim of this study was to evaluate salivary vitamin C and catalase levels in HIV-positive patients in comparison to a healthy control group. Forty-nine HIV-infected individuals and 49 healthy subjects were selected. Five mL of unstimulated saliva was collected in 5 minutes using a sterilized Falcon tube with Navazesh method. Catalase and vitamin C levels were assessed by spectrophotometric assay. Data were analyzed with STATA 12. Salivary catalase levels were 7.99±2.40 and 8.37±1.81 in the case and control groups, respectively. Catalase level was lower in the case group but the difference was not statistically significant (P=0.380). Salivary vitamin C levels in the case and control groups were 3.76±1.92 and 4.87±2.20, respectively (P=0.009). HIV can alter salivary antioxidant capacity as well as vitamin C and catalase levels. Saliva may reflect serum antioxidative changes in these patients. Therefore, further research is necessary on salivary and serum oxidants and the antioxidant changes.

HIV antigenemia was found in 52/243 HIV antibody positive individuals attending 2 AIDS-screening clinics, giving a prevalence of 13, 25 and 76% in CDC groups II, III and IV, respectively. No correlation was found to decreased CD4 lymphocyte values in the individual groups. HIV antigen therefore...... identified a separate subpopulation. For 138 asymptomatic patients followed prospectively both laboratory parameters predicted HIV-related events, the relative risk factor being 4 for low CD4 value and 6 for presence of HIV antigen. Individuals presenting with HIV antigen and decreased CD4 count all...... developed disease within 18 months, the relative risk factor being 24. Thus the 2 markers, when measured together, effectively separated asymptomatic HIV-infected patients into 1 of 3 risk categories....

This study examined substance use (intended and actual), unprotected sex, and HIV disclosure practices (disclosure and questioning) among HIV-positive men who have sex with men (MSM) at two party-oriented vacations, where substance use and sexual risk may be heightened. A random sample of 489 MSM attending one of two party-oriented vacations participated in PartyIntents, a short-term longitudinal survey. Nearly half (47%) completed a follow-up assessment at the event or online for up to 2 weeks after the event. We examined rates of baseline intentions to use substances, actual substance use, and unprotected intercourse among HIV-positive men in attendance.Rates among HIV-negative men were estimated for comparison. Multiple logistic regression was used to assess the impact of illegal drug use and HIV status on unprotected anal intercourse (UAI). HIV-positive attendees (17%) were significantly more likely than HIV-negative attendees to use nitrite inhalants (or "poppers") (24.3% vs. 10.7%). HIV-positive attendees were also significantly more likely to have insertive UAI (64.3% vs. 34.1%) and receptive UAI (68.8% vs. 22.2%). Multivariate models showed associations between HIV status and illegal drug use with UAI (for HIV status, odds ratio [OR] = 4.5, p = .001; for any illegal drug use, OR = 16.4, p < .001). There was no evidence that the influence of drug use moderated risk by HIV status. Rates of HIV disclosure and questioning did not differ by HIV status. HIV-positive men attending these events engaged in higher rates of illegal drug use and sexual risk than HIV-negative men. Prevention campaigns targeting MSM at high-risk events should include messages geared toward HIV-positive men.

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

Human thymus can be infected by HIV-1 with potential consequences on immune regeneration and homeostasis. We previously showed that CD4 thymocytes preferentially replicate CXCR4 tropic (X4) HIV-1 dependently on interleukin (IL)-7. Here we addressed the susceptibility of thymic dendritic cells (DC) to HIV-1 infection. We investigated the replication ability of CXCR4 or CCR5 (R5) tropic HIV-1 in thymic micro-explants as well as in isolated thymic CD11clowCD14- DC, CD11chighCD14+ DC and plasmacytoid DC subsets. Thymic tissue was productively infected by both X4 and R5 viruses. However, X4 but not R5 HIV-1 replication was enhanced by IL-7 in thymic micro-explants, suggesting that R5 virus replication occurred in cells other than thymocytes. Indeed, we found that R5 HIV-1 replicated efficiently in DC isolated from thymic tissue. The replicative capacity of X4 and R5 viruses differed according to the different DC subsets. R5 but not X4 HIV-1 efficiently replicated in CD11chighCD14+ DC. In contrast, no HIV-1 replication was detected in CD11clowCD14- DC. Both X4 and R5 viruses efficiently replicated in plasmacytoid DC, which secreted interferon-alpha upon HIV-1 exposure. Productive HIV-1 infection also caused DC loss, consistent with different permissivity of each DC subset. Thymic DC sustain high levels of HIV-1 replication. DC might thus be the first target for R5 HIV-1 infection of thymus, acting as a Trojan horse for HIV-1 spread to thymocytes. Furthermore, DC death induced by HIV-1 infection may affect thymopoiesis.

The WHO guidelines for children less than 18 months old diagnosed with HIV based on presumptive clinical diagnosis or one virologic test recommend confirmatory HIV antibody testing after 18 months of age. This study describes post-18-month HIV test results following this WHO-recommended confirmatory testing strategy. Case series and retrospective review of routine program data. Children enrolled at the Baylor Children's Clinical Center of Excellence, a pediatric and family HIV clinic in Maseru, Lesotho from December 2005 through January 2009 with a positive HIV DNA PCR at less than 18 months of age and HIV rapid test results after 18 months of age were included. Post-18-month confirmatory HIV test results are described. Factors associated with non-positive confirmatory rapid tests were determined using binary logistic regression. Of the 109 children meeting inclusion criteria, 22 (20.2%) had negative and 27 (24.8%) discordant confirmatory rapid tests. Forty-six of these 49 were on antiretroviral therapy (ART). Among these 49, 11 of 24 post-18-month HIV DNA PCRs were negative, whereas nine of 10 post-18-month HIV ELISAs were positive; 29 were definitively and 17 probably HIV-infected, two were uninfected, and one had undetermined status. Only age less than 9 months at ART initiation (odds ratio 4.25, P = 0.002) was associated with non-positive rapid tests. False-negative post-18-month confirmatory rapid tests and HIV DNA PCRs in children on ART are common, associated with early ART initiation, and may lead to inappropriate ART discontinuation and discharge from care of truly HIV-infected children.

Background The increased risk of coronary artery disease in human immunodeficiency virus (HIV) positive patients is collectively contributed to by the human immunodeficiency virus and antiretroviral-associated dyslipidaemia. In this study, we investigate the characterisation of the plasma lipid profiles of treated HIV patients and the relationship of 316 plasma lipid species across multiple lipid classes with the risk of future cardiovascular events in HIV- positive patients. Methods In a retrospective case-control study, we analysed plasma lipid profiles of 113 subjects. Cases (n = 23) were HIV-positive individuals with a stored blood sample available 12 months prior to their diagnosis of coronary artery disease (CAD). They were age and sex matched to HIV-positive individuals without a diagnosis of CAD (n = 45) and with healthy HIV-negative volunteers (n = 45). Results Association of plasma lipid species and classes with HIV infection and cardiovascular risk in HIV were determined. In multiple logistic regression, we identified 83 lipids species and 7 lipid classes significantly associated with HIV infection and a further identified 74 lipid species and 8 lipid classes significantly associated with future cardiovascular events in HIV-positive subjects. Risk prediction models incorporating lipid species attained an area under the receiver operator characteristic curve (AUC) of 0.78 (0.775, 0.785)) and outperformed all other tested markers and risk scores in the identification of HIV-positive subjects with increased risk of cardiovascular events. Conclusions Our results demonstrate that HIV-positive patients have significant differences in their plasma lipid profiles compared with healthy HIV-negative controls and that numerous lipid species were significantly associated with elevated cardiovascular risk. This suggests a potential novel application for plasma lipids in cardiovascular risk screening of HIV-positive patients. PMID:24733512

Risk prediction models incorporating lipid species attained an area under the receiver operator characteristic curve (AUC) of 0.78 (0.775, 0.785)) and outperformed all other tested markers and risk scores in the identification of HIV-positive subjects with increased risk of cardiovascular events. Our results demonstrate that HIV-positive patients have significant differences in their plasma lipid profiles compared with healthy HIV-negative controls and that numerous lipid species were significantly associated with elevated cardiovascular risk. This suggests a potential novel application for plasma lipids in cardiovascular risk screening of HIV-positive patients.

The entry into both HIV care and secondary prevention is first through the knowledge of one's own HIV status. Testing for HIV remains challenging in countries where clinicians rely on rapid testing algorithms because the routine use of confirmatory Western blot technology is unavailable. In this case report, we describe the case of a pregnant woman in Niger, who was falsely labeled as HIV positive during prenatal visits. We also describe our clinical algorithm that was developed to facilitate retesting in patients who initially tested HIV positive or indeterminant with rapid diagnostic tests. Vigilance is necessary to ensure that appropriate identification and treatment of HIV is provided to reduce mother-to-child transmission of HIV, to appropriately allocate resources, and to avoid falsely labeling patients with HIV. © The Author(s) 2015.

The purpose of this analysis was to estimate human immunodeficiency virus (HIV) prevalence and testing patterns among injection drug users (IDUs) in St. Petersburg, Russia. HIV prevalence among 387 IDUs in the sample was 50%. Correlates of HIV-positive serostatus included unemployment, recent unsafe injections, and history/current sexually transmitted infection. Seventy-six percent had been HIV tested, but only 22% of those who did not report HIV-positive serostatus had been tested in the past 12 months and received their test result. Correlates of this measure included recent doctor visit and having been in prison or jail among men. Among the 193 HIV-infected participants, 36% were aware of their HIV-positive serostatus. HIV prevalence is high and continuing to increase in this population. Adequate coverage of HIV testing has not been achieved, resulting in poor knowledge of positive serostatus. Efforts are needed to better understand motivating and deterring factors for HIV testing in this setting. PMID:18843531

Full Text Available Aim. To determine changes in adherence to antiretroviral therapy (ART in HIV-positive patients with depression, following treatment with an antidepressant or psychotherapy. Methods. The study was prospective, randomised and controlled. Consenting volunteers aged ≥18 years and stable on ART for ≥6 months were included in the study. Sociodemographic data were obtained, and a clinical diagnostic evaluation and the Hamilton Depression rating scale (HAMD were performed on all subjects at entry to and at the end of the study. Participants found to be depressed were randomly assigned antidepressant treatment (20 mg citalopram or interpersonal psychotherapy (IPT (5 sessions. Medication was dispensed at each visit and patients were asked to return all unused medication to determine ART adherence. The study was approved by the University of the Witwatersrand. Results. Sixty-two HIV-positive persons receiving ART participated; 30 were not depressed (control group and 32 were depressed (patient group. No significant differences in demographic characteristics existed between the control and patient groups. Mean ART adherence at the start of the study was 99.5% (standard error (SE ±0.46 and 92.1% (SE ±1.69 in the control and patients groups, respectively. Mean ART adherence at the end of the study changed marginally in the control group (99.7%; SE ±0.46 and increased significantly in the patient group (99.5%; SE± 0.13 (p>0.05. The mean ART adherence rate of patients who received pharmacotherapy increased from 92.8% to 99.5%, and of those who received psychotherapy increased from 91.1% to 99.6% (p>0.05.

Characterization of Candida albicans isolates from the oral cavity of Ethiopian Human Immunodeficiency Virus (HIV)-positive patients and HIV-negative individuals was undertaken. After identification of isolates using conventional methods and determination of carbohydrate assimilation profiles, serotyping was performed by slide agglutination with the Iatron IF6 serotyping system. Sensitivity of the isolates to 5-Fluorocytosine (5-FC) was assessed using the broth macrodilution method. There was no difference in phenotype, by any of the three methods used, between the HIV-positive and HIV-negative individuals. Serotype A was found to be dominant in strains isolated from both HIV-positive (34/40 = 85%) and HIV-negative (17/20 = 85%) study subjects. These data suggest that the C. albicans strains causing oral candidiasis in patients with HIV infection are identical to the commensal ones found in healthy individuals.

This priority was identified by a disability advocacy organization in Lusaka, Zambia, where the prevalence of HIV and of disability is each approximately 15%. The purpose of this study was to explore perceptions and experiences of HIV-related health services for PWDs who are also living with HIV in Lusaka, Zambia. Methods: This qualitative, interpretive study involved in-depth, semi-structured, one-on-one interviews with two groups of participants in Lusaka, Zambia: 21 PWDs who had become HIV-positive, and 11 people working in HIV and/or disability. PWDs had physical, hearing, visual and/or intellectual impairments. Interviews were conducted in English, Nyanja, Bemba or Zambian sign language.

Incarcerated women face significant barriers to achieve continuous HIV care. We employed a descriptive, exploratory design using qualitative methods and the theoretical construct of agency to investigate participants' self-reported experiences accessing HIV services in jail, in prison, and post-release in two Alabama cities. During January 2014, we conducted in-depth interviews with 25 formerly incarcerated HIV-positive women. Two researchers completed independent coding, producing preliminary codes from transcripts using content analysis. Themes were developed iteratively, verified, and refined. They encompassed (a) special rules for HIV-positive women: isolation, segregation, insults, food rationing, and forced disclosure; (b) absence of counseling following initial HIV diagnosis; and (c) HIV treatment impediments: delays, interruption, and denial. Participants deployed agentic strategies of accommodation, resistance, and care-seeking to navigate the social world of prison and HIV services. Findings illuminate the "HIV prison paradox": the chief opportunities that remain unexploited to engage and re-engage justice-involved women in the HIV care continuum.

Full Text Available BACKGROUND: Reverse transcriptase is a major drug target in highly active antiretroviral therapy (HAART against HIV, which typically comprises two nucleoside/nucleotide analog reverse transcriptase (RT inhibitors (NRTIs in combination with a non-nucleoside RT inhibitor or a protease inhibitor. Unfortunately, HIV is capable of escaping the therapy by mutating into drug-resistant variants. Computational models that correlate HIV drug susceptibilities to the virus genotype and to drug molecular properties might facilitate selection of improved combination treatment regimens. METHODOLOGY/PRINCIPAL FINDINGS: We applied our earlier developed proteochemometric modeling technology to analyze HIV mutant susceptibility to the eight clinically approved NRTIs. The data set used covered 728 virus variants genotyped for 240 sequence residues of the DNA polymerase domain of the RT; 165 of these residues contained mutations; totally the data-set covered susceptibility data for 4,495 inhibitor-RT combinations. Inhibitors and RT sequences were represented numerically by 3D-structural and physicochemical property descriptors, respectively. The two sets of descriptors and their derived cross-terms were correlated to the susceptibility data by partial least-squares projections to latent structures. The model identified more than ten frequently occurring mutations, each conferring more than two-fold loss of susceptibility for one or several NRTIs. The most deleterious mutations were K65R, Q151M, M184V/I, and T215Y/F, each of them decreasing susceptibility to most of the NRTIs. The predictive ability of the model was estimated by cross-validation and by external predictions for new HIV variants; both procedures showed very high correlation between the predicted and actual susceptibility values (Q2=0.89 and Q2ext=0.86. The model is available at www.hivdrc.org as a free web service for the prediction of the susceptibility to any of the clinically used NRTIs for any HIV

We evaluated the risk factors associated with oral human papillomavirus (HPV) infection and oral lesions in 161 human immunodeficiency virus (HIV)-positive patients and 128 HIV-negative patients presenting for oral examination at 2 urban healthcare centers. Patients were interviewed on risk factors and provided oral-rinse samples for HPV DNA typing by polymerase chain reaction. Statistical associations were assessed by logistic regression. Oral HPV was prevalent in 32% and 16% of HIV-positive patients and HIV-negative patients, respectively, including high-risk HPV type 16 (8% and 2%, respectively; P = .049) and uncommon HPV types 32/42 (6% and 5%, respectively; P = .715). Among HIV-negative patients, significant risk factors for oral HPV included multiple sex partners (≥21 vs ≤5; odds ratio [OR], 9.1; 95% confidence interval [CI], 1.7-49.3), heavy tobacco smoking (>20 pack-years vs none; OR, 9.2; 95% CI, 1.4-59.4), and marijuana use (OR, 4.0; 95% CI, 1.3-12.4). Among HIV-positive patients, lower CD4(+) T-cell count only was associated with oral HPV detection (≤200 vs ≥500 cells/mm(3); OR, 4.5; 95% CI, 1.3-15.5). Detection of high-risk HPV was also associated with concurrent detection of potentially cancerous oral lesions among HIV-negative patients but not among HIV-positive patients. The observed risk factor associations with oral HPV in HIV-negative patients are consistent with sexual transmission and local immunity, whereas in HIV-positive patients, oral HPV detection is strongly associated with low CD4(+) T-cell counts. © The Author 2015.

Families affected by HIV/AIDS in the developing world experience higher risks of psychosocial problems than nonaffected families. Positive parenting behavior may buffer against the negative impact of child AIDS-orphanhood and caregiver AIDS-sickness on child well-being. Although there is substantial literature regarding the predictors of parenting behavior in Western populations, there is insufficient evidence on HIV/AIDS as a risk factor for poor parenting in low- and middle-income countries. This paper examines the relationship between HIV/AIDS and positive parenting by comparing HIV/AIDS-affected and nonaffected caregiver-child dyads (n=2477) from a cross-sectional survey in KwaZulu-Natal, South Africa (27.7% AIDS-ill caregivers; 7.4% child AIDS-orphanhood). Multiple mediation analyses tested an ecological model with poverty, caregiver depression, perceived social support, and child behavior problems as potential mediators of the association of HIV/AIDS with positive parenting. Results indicate that familial HIV/AIDS's association to reduced positive parenting was consistent with mediation by poverty, caregiver depression, and child behavior problems. Parenting interventions that situate positive parenting within a wider ecological framework by improving child behavior problems and caregiver depression may buffer against risks for poor child mental and physical health outcomes in families affected by HIV/AIDS and poverty.
Full Text Available HIV infection is associated with increased incidence of malignancies, such as lymphomas and testicular cancers. We reviewed the relationship between HIV infection and prostate cancer in a contemporary series of prostate biopsy patients. The study is a retrospective analysis of consecutive prostate biopsies performed at a VA Medical Center. The indications for performing a prostate biopsy included an abnormal digital rectal examination and/or an elevated PSA. Patients were categorized according to their HIV status, biopsy results, and various demographic and clinical characteristics. Univariate and multivariate analyses compared distributions of HIV status, and various clinical and demographic characteristics. The adjusted measures of association between HIV status and positive biopsy were expressed as odds ratios (ORs and corresponding 95% confidence intervals (CI. The likelihood of positive biopsy was significantly higher among 18 HIV-positive patients compared to patients with negative HIV tests (adjusted OR = 3.9; 95% CI: 1.3–11.5. In analyses restricted to prostate cancer patients, HIV-positive patients were not different from the remaining group with respect to their prostate cancer stage, PSA level, PSA velocity, PSA density, or Gleason grade. There is an association between HIV infection and prostate biopsy positive for carcinoma in a population referred for urologic workup. Further confirmation of this association by prospective studies may impact the current screening practices in HIV patients.

HIV positive mothers, who choose not to breastfeed their babies in a predominantly breastfeeding community would face a number of barriers. This study looked at the experiences of HIV positive mothers who chose the no breastfeeding option. Consecutive HIV positive mothers who opted not to breastfeed their infants after infant feeding counselling and whose infants were attending the HIV programme at the University of Benin Teaching Hospital, Benin City, Nigeria were recruited for the study. Disclosure of HIV serostatus and adherence to no breastfeeding options were evaluated using an interviewer administered structured questionnaire. Of the 62 mothers recruited for the study, 57 (91.94 %) had disclosed their serostatus to at least their partners. Most partners 42 (93.33%) were supportive while three mothers were divorced following disclosure. Thirteen (20.97%) mothers could not comply with no breastfeeding. Non disclosure of serostatus, pressure from extended family and token breastfeeding mitigate against adhering to no breastfeeding by HIV positive mothers.

It is a phenomenon linked with human immunodeficiency virus (HIV infection, although association rates in Angola are currently unknown. A topical treatment that is effective in HIV-positive and HIV-negative individuals may be preferable to surgery in some contexts. We aimed to estimate the proportion of OSSN associated with HIV in Angola and to report on the success of topical 5-fluorouracil as a primary treatment in HIV-positive and HIV-negative patients.Methods: Photographs of OSSNs taken at presentation and following treatment with 5-fluorouracil in patients presenting to Boa Vista Eye Clinic, Angola, between October 2011 and July 2013 were grouped into HIV-positive and HIV-negative groups and analyzed to compare presenting features and treatment response. Eighty-one OSSNs were analyzed for clinical features and 24 met the inclusion criteria for analysis of treatment response.Results: Eighty-two patients presented with OSSN between October 2011 and July 2013. Twenty-one (26% were HIV-positive and typically had OSSNs that exhibited more pathological features than those in HIV-negative patients. Twenty-four (29% patients met the inclusion criteria for analysis of treatment response; of these, 26 (91% OSSNs in both groups displayed at least partial resolution after one treatment course. In the HIV-positive group, five of eight patients displayed complete resolution, two showed partial resolution, and one failed. In the HIV-negative group, five of 16 showed complete resolution, ten of 16 had partial resolution, and one failed.Conclusion: Individuals presenting with OSSN in Angola are more likely to have HIV infection compared

NK cells are a part of the innate antiviral response. Their activity is regulated by signals from the surface receptors. Some of them, known as killer cell immunoglobulin-like receptors (KIRs), determine the quality and intensity of the immunological response, together with their ligands (HLA class I). KIR genes are very polymorphic, and this is reflected in the NK activity modulation. The stimulation of NK cells, especially in the early stages of the infection, can reduce the transmission of HIV or slow down the progression of infection. The varied KIR/HLA repertoire is a limiting factor for the risk of HIV infection and disease progression. Such diversity enables optimal regulation of NK cells and maintenance of the balance between activation to eliminate infected cells and inhibition. The control of NK cell activity via KIR3DL1/3DS1 and HLA-Bw4 (especially Bw4-80I) seems to be very important in the HIV context. With a few exceptions, it leads to a reduction of susceptibility to HIV infection and better viremia control, and slows down depletion of CD4+ T cells. Incompatibility of sexual partners for KIRs and HLA may oblige NK cells from the exposed partner to reject incoming cells from the HIV-positive partner. The presence of the inhibitory KIR, in the absence of its ligand, results in a lower threshold of NK cell activation, which reduces the chance of infection. The presence of an inhibitory receptor with a low affinity to the ligand (KIR2DL3+HLA-C1) is associated with lower susceptibility, and the effective NK cell inhibition (KIR2DL2+HLA-C1) results in increased susceptibility to HIV infection. The advantage of activating KIRs, especially in the presence of their ligands, is associated with higher cytolytic abilities, and thus reduced risk of HIV infection. If the virus is not eliminated in an early stage of infection, massive activation of NK is unfavorable due to the excessive stimulation of the immune system.

One of the crucial determinants for successful administration of lactobacilli to the vaginal niche is the use of appropriate Lactobacillus species. In this cross-sectional study 54 human immunodeficiency virus (HIV)-negative and 76 HIV-positive antiretroviral treatment-naïve women were evaluated for culturable vaginal lactobacilli and their association with genital HIV-1 shedding. Lactobacillus species were identified by 16S rDNA sequencing while cervical and plasma HIV-1 viral load was determined by Abbott real-time PCR. Lactobacilli were isolated in 77.8 % HIV-negative and 73.7 % HIV-positive women. The mean log10 plasma and cervical HIV-1 viral loads (RNA copies ml(-1)) were 3.73±1.02 and 2.85±0.32 respectively. We observed that presence of L. crispatus, L. gasseri or L. jensenii species was associated with undetectable cervical HIV-1 (P=0.046) and reduced genital HIV-1 shedding (P=0.048) compared to other species. Our findings endorse using Lactobacillus-based strategies to aid the prevention of HIV-1 transmission among Indian women, however confirmation by future prospective studies is indeed warranted.

Understanding the fertility of HIV-positive women is critical to estimating HIV epidemic trends from surveillance data and to planning resource needs and coverage of prevention of mother-to-child transmission services in sub-Saharan Africa. In the light of the considerable scale-up in antiretroviral therapy (ART) coverage over the last decade, we conducted a systematic review of the impact of ART on the fertility outcomes of HIV-positive women. We searched Medline, Embase, Popline, PubMed and African Index Medicus. Studies were included if they were conducted in sub-Saharan Africa and provided estimates of fertility outcomes (live births or pregnancies) among women on ART relative to a comparison group. Of 2070 unique references, 18 published papers met all eligibility criteria. Comparisons fell into four categories: fertility of HIV-positive women relative to HIV-negative women; fertility of HIV-positive women on ART compared to those not yet on ART; fertility differences by duration on ART; and temporal trends in fertility among HIV-positive women. Evidence indicates that fertility increases after approximately the first year on ART and that while the fertility deficit of HIV-positive women is shrinking, their fertility remains below that of HIV-negative women. These findings, however, were based on limited data mostly during the period 2005-2010 when ART scaled up. Existing data are insufficient to characterise how ART has affected the fertility of HIV-positive women in sub-Saharan Africa. Improving evidence about fertility among women on ART is an urgent priority for planning HIV resource needs and understanding HIV epidemic trends. Alternative data sources such as antenatal clinic data, general population cohorts and population-based surveys can be harnessed to understand the issue. © 2016 John Wiley & Sons Ltd.
Full Text Available This paper aimed to investigate the brain activity of human immunodeficiency virus (HIV positive patients with normal cognition during unilateral hand movement and whether highly active antiretroviral therapy (HAART could affect the brain function. Functional magnetic resonance imaging (fMRI was performed for 60 HIV positive (HIV+ subjects and −42 healthy age-matched right-handed control subjects. Each subject was evaluated by the neuropsychological test and examined with fMRI during left and right hand movement tasks. HIV+ subjects showed greater activation in anterior cingulum, precuneus, occipital lobes, ipsilateral postcentral gyrus and contralateral cerebellum compared with control group during right hand movement task. However, during left hand movement no statistically significant difference was detected between these two groups. HAART medication for HIV+ subjects lowered the increased activity to normal level. Meanwhile patients receiving the regimen of zidovudine, lamivudine and efavirenz showed lower activity at bilateral caudate and ipsilateral inferior frontal gyrus in comparison with subjects receiving other HAART regimens. Therefore, HIV+ subjects demonstrated brain asymmetry in motor cortex, with increased activity present during right hand movement but absent during left hand movement. HAART proves effective in HIV+ subjects even with normal cognition and the specific regimen of HAART could prevent cerebral abnormal functions. Meanwhile, this study validates that during motor tasks, fMRI can detect the brain signal changes prior to the occurrences of other HIV- associated dysfunctions.

Full Text Available Background: There is an increasing incidence of Human immunodeficiency virus (HIV and tuberculosis (TB co-infection. This has led to an increasing number of atypical features on magnetic resonance imaging (MRI. We postulated that the type 4 hypersensitivity response causing granulomatous inflammation may be disrupted by the HIV resulting in less vertebral body destruction. This study compares the MRI features of spinal tuberculosis in HIV positive and negative patients. Materials and Methods: Fifty patients with confirmed spinal tuberculosis, HIV status and available MRI scans at a single institution from 2003-2009 were identified. HIV status was positive in 20 and negative in 30. Females were predominant (34:16. The HIV positive group was younger at 32.4 versus 46 years (P=0.008. Blood parameters (WCC, ESR, Hb, Lymphocyte count were not significantly different between the HIV groups. MRI scans were reviewed by a radiologist who was blinded to the HIV status. Site, extent of disease, body collapse, abscess location and volume, kyphotic deformity and cord signal were reported. Results: There was no difference between the number of vertebral bodies affection with TB involvement, presence of cord signal or incidence of non-contiguous lesions. The HIV negative group had significantly more total vertebral collapse (P=0.036 and greater kyphosis (P=0.002. The HIV positive group had a trend to larger anterior epidural pus collection (P=0.2. Conclusion: HIV negative patients demonstrate greater tuberculous destruction in terms of total percentage body collapse and resultant kyphosis. There is no difference in the incidence of cord signal or presence of non-contiguous lesions. HIV positive patients show a trend to a greater epidural abscess volume. This difference may be explained by the reduced autoimmune response of the type 4 hypersensitivity reaction caused by the HIV infection.

In this study, we examined how non-infectiousness due to antiretroviral therapy has affected HIV-positive gay men's experience of serostatus disclosure to casual sex partners. Interviews were conducted with 15 seropositive gay men living in Ireland. Using grounded theory, three constructions of non-disclosure were proposed-as self-protection, as a morally permissible act, and as a rejection of the HIV-positive identity. Each construction entailed an aspect related to the sexual exclusion of those living with HIV, and an aspect related to their social exclusion. The extent to which the lives of those interviewed were affected by stigma was starkly revealed, as was the extent to which they stigmatized others living with HIV and rejected the HIV-positive identity. The research highlights the failure to socially normalize HIV and that interventions are needed to reduce the distress associated with seropositivity. © The Author(s) 2015.

Whether perceived or enacted, HIV-related stigma is widespread in India, and has had a crippling effect on People Living with HIV/AIDS (PLHA). Research has shown that a positive attitude towards the illness sets a proactive framework for the individual to cope with his or her infection; therefore, healthy coping mechanisms are essential to combat HIV-related stigma. This qualitative study involving in-depth interviews and focus group discussions with PLHA affiliated with HIV support groups in South India explored positive coping strategies employed by PLHA to deal with HIV-related stigma. Interviews and focus group discussions were translated, transcribed, and analyzed for consistent themes. Taboos surrounding modes of transmission, perceiving sex workers as responsible for the spread of HIV, and avoiding associating with PLHA provided the context of HIV-related stigma. Despite these challenges, PLHA used several positive strategies, classified as Clear Knowledge and Understanding of HIV, Social Support and Family Well-Being, Selective Disclosure, Employment Building Confidence, and Participation in Positive Networks. Poor understanding of HIV and fears of being labeled immoral undermined healthy coping behavior, while improved understanding, affiliation with support groups, family support, presence of children, and financial independence enhanced PLHA confidence. Such positive coping behaviours could inform culturally relevant interventions.

In Sweden, human immunodeficiency virus (HIV) is included among the venereal diseases covered by the Law of Communicable Diseases Act. HIV-positive (HIV+) people are required to inform their sexual partners about their infection and adopt safe sex behaviours. However, it is unclear how the law is perceived. This study explores how HIV+ youth in Sweden perceive the law, handle their sexuality and disclose their HIV diagnosis to sexual partners. Ten HIV+ women and men between 17 and 24 years of age were recruited from three different HIV infection clinics. These participants were interviewed in depth. The interviews were tape-recorded, transcribed verbatim and analysed according to a grounded theory approach. The core category—cultured to take responsibility—illuminates the informants’ double-edged experiences regarding the law and how they handle disclosure to sexual partners. The legislation implies both support and burden for these HIV+ youth; they feel that they have a great deal of responsibility, sometimes more than they can handle. ‘Switch off lust’, ‘balancing lust, fear and obedience’ and ‘switch off the disease’ are strategies that describe how the informants manage sexuality and disclosure. Young HIV+ people have a difficult time informing partners of their HIV diagnosis and discussing safe sex strategies. These are challenges that health care providers need to take seriously. HIV+ youth need better communication strategies to negotiate safer sex. Staff with extended education on sexuality should be a part of HIV health care. PMID:22639678

Mass spectrometry Matrix-Assisted Laser Desorption-Ionization Time-of-Flight (MALDI-TOF) helps in the rapid identification of microorganisms causing blood stream infection. Rapid and reliable methods are required to decrease the turnaround time for reporting antimicrobial susceptibility results from blood culture isolates. An evaluation was performed on the reliability of a method for antimicrobial susceptibility testing of positive blood culture isolates from briefly incubated solid medium cultures. The agreement between the evaluated and standard methods was 99.3%. The major and minor error rates were 0.4% and 0.3%, respectively, and no very major errors were observed. The inoculation of briefly incubated solid medium cultures into antimicrobial susceptibility testing panels is an easy and reliable technique, and helps to decrease the turnaround time for reporting antimicrobial susceptibility results of positive blood cultures.

In Ukraine, about one-third of identified HIV-positive individuals are not connected to care. We conducted a cross-sectional survey (n = 200) among patients registered at Odessa AIDS centers in October to December 2011. Factors associated with delayed enrollment in HIV care (>3 months since positive HIV test) were evaluated using logistic regression. Among study participants (mean age 35 ± 8.2 years, 47.5% female, 42.5% reported history of injecting drugs), 55% delayed HIV care enrollment. Odds of delayed enrollment were higher for those with lower educational attainment (adjusted odds ratio [aOR]: 2.65, 95% confidence interval [CI]: 1.04-6.76), not feeling ill (aOR: 2.98, 95% CI: 1.50-5.93), or not having time to go to the AIDS center (aOR: 3.89, 95% CI: 1.39-10.89); injection drug use was not associated with delayed enrollment. Programs linking HIV-positive individuals to specialized care should address enrollment barriers and include education on HIV care benefits and case management for direct linkage to care. HIV testing and treatment should be coupled to ensure a continuum of care.

High-risk human papillomavirus (HR-HPV) viral load is associated with HR-HPV transmission and HR-HPV persistence in women. It is unknown whether HR-HPV viral load is associated with persistence in HIV-negative or HIV-positive men. HR-HPV viral load and persistence were evaluated among 703 HIV-negative and 233 HIV-positive heterosexual men who participated in a male circumcision trial in Rakai, Uganda. Penile swabs were tested at baseline and 6, 12 and 24 months for HR-HPV using the Roche HPV Linear Array, which provides a semiquantitative measure of HPV shedding by hybridisation band intensity (graded: 1-4). Prevalence risk ratios (PRR) were used to estimate the association between HR-HPV viral load and persistent detection of HR-HPV. HR-HPV genotypes with high viral load (grade:3-4) at baseline were more likely to persist than HR-HPV genotypes with low viral load (grade: 1-2) among HIV-negative men (month 6: adjPRR=1.83, 95% CI 1.32 to 2.52; month 12: adjPRR=2.01, 95% CI 1.42 to 3.11), and HIV-positive men (month 6: adjPRR=1.33, 95% CI 1.06 to 1.67; month 12: adjPRR=1.73, 95% CI 1.18 to 2.54). Long-term persistence of HR-HPV was more frequent among HIV-positive men compared with HIV-negative men (month 24: adjPRR=2.27, 95% CI 1.47 to 3.51). Persistence of newly detected HR-HPV at the 6-month and 12-month visits with high viral load were also more likely to persist to 24 months than HR-HPV with low viral load among HIV-negative men (adjPRR=1.67, 95% CI 0.88 to 3.16). HR-HPV genotypes with high viral load are more likely to persist among HIV-negative and HIV-positive men, though persistence was more common among HIV-positive men overall. The results may explain the association between high HR-HPV viral load and HR-HPV transmission. Published by the BMJ Publishing Group Limited.

Full Text Available Background. Human dendritic cell-specific intracellular adhesion molecule-3 (ICAM3-grabbing non-integrin (DC-SIGN is a mannose-binding lectin that initiates interaction between dendritic cells and resting T-lymphocytes. DC-SIGN is highly expressed in placental tissue on dendritic cells and Hofbauer cells, and it is suggested that HIV may become adsorbed to DC-SIGN on Hofbauer cells as part of the mechanism of mother-to-child HIV transmission. A possible mechanism of transfer of the virus from the Hofbauer cells to the fetus is the subsequent adsorption to DC-SIGN-related molecules (DC-SIGNRs, present on immediately adjacent capillary vascular endothelium. However, data on DC-SIGN and DC-SIGNR expression in the placenta are few.Methods. Forty term placentas from HIV-positive mothers and 21 term placentas from HIV-negative mothers underwent immunohistochemistry staining for DC-SIGN and DC-SIGNR expression. Five random sets of 10 villi were assessed, and the average number of positive cells were counted in each case. In addition, where possible, maternal and cord blood viral loads and maternal CD4+ counts were performed in the HIV-positive group only.Results. The median maternal CD4+ count was 377 cells/µl and 27% of participants had undetectable viral loads; the median detectable viral load was 3.72 log. Most (97% of the cord bloods tested in infants from HIV-positive mothers had lower than detectable viral loads. HIV-positive cases had significantly greater expression of both DC-SIGNRs (median values in HIV-positive cases, 14.5 positive cells/10 villi (pc/10villi, compared with 11 pc/10villi in HIV-negative cases, p=0.020 and DC-SIGN (median value in HIV-positive cases, 26.5 pc/10villi, compared with 23 pc/10villi in HIV-negative cases, p=0.037. DC-SIGNR expression was also noted in Hofbauer cells and decidual macrophages in addition to endothelium (reported currently. There was no difference in expression of DC-SIGN and DC-SIGNRs in patients
Full Text Available ABSTRACT One of the factors causing treatment failure in cryptococcosis is the resistance of Cryptococcus spp. to antifungal drugs, which has motivated the susceptibility assessment of isolates from patients with cryptococcosis, different clinical conditions and infections outcomes. Clinical isolates of Cryptococcus spp. from three different groups of patients were studied in the present investigation: 19 HIV-positive patients with relapsing and/or refractory meningitis (Group 1, 30 HIV-positive patients who experienced a single and limited episode of cryptococcosis (Group 2, and 19 HIV-negative patients with cryptococcosis (Group 3. Eighty C. neoformans var. grubii isolates and 7 C. gattii isolates were studied. The minimum inhibitory concentration (MIC of amphotericin B, azole drugs and flucytosine was determined for Cryptococcus spp. by broth microdilution test and E-test. The MIC50 and MIC90 were 0.25 and 0.50 µg/mL for amphotericin B, 4.0 and 8.0 µg /mL for fluconazole, 0.06 and 0.25 µg/mL for itraconazole, 0.25 and 0.50 µg/mL for voriconazole, and 8.0 and 16.0 µg/mL for flucytosine, respectively. Amphotericin B and itraconazole showed higher MICs for C. neoformans var. grubii and C. gattii, respectively. The MICs of fluconazole and itraconazole obtained with the E-test were higher than those obtained with broth microdilution. Isolates from non-HIV coinfected were less sensitive to the azoles. There was no difference in the susceptibility of C. neoformans var. grubii isolates from patients with a favorable or unfavorable outcome or along the episodes of relapsing and/or refractory meningitis.

There are conflicting reports concerning the prevalence of Mycoplasma fermentans in HIV-positive patients and its association with AIDS. Serum antibodies to M. fermentans were measured by a modified immunoblotting technique in 48 HIV-positive heterosexual patients and in 30 HIV-negative heterosexual controls. Antibodies to M. fermentans were detected in 19 (40%) of HIV-positive patients and in three (10%) of the HIV-negative controls (P = 0.01). The prevalence of antibodies to Mycoplasma hominis and to Ureaplasma urealyticum was similar in both groups. In the HIV-positive group, 16/19 (84%) M. fermentans-positive patients developed AIDS, compared to eight of 29 (28%) M. fermentans-negative patients (P = 0.0004). The HIV-positive patients with antibodies to M. fermentans had a lower CD4+ cell count and a higher prevalence of antibodies to the other mycoplasma tested (P = 0.007 and P = 0.03, respectively), as compared to the patients without antibodies to M. fermentans. These findings may suggest that the presence of antibodies to M. fermentans indicate an opportunistic infection. Of the 19 M. fermentans-positive patients, 11 were positive on the first examination, and eight became positive during the follow-up period. Seven out of these eight patients developed antibodies to M. fermentans before the development of AIDS. Therefore, the possibility exists that M. fermentans might influence the development of AIDS.

To analyze the characteristics of risky behaviors among different age groups of HIV positive female sex workers, and to explore the strengthening of their management. From January to June 2014, 22 814 female sex workers were investigated and tested HIV in 117 sentinel surveillance sites in Yunnan Province, and 181 were confirmed to be HIV antibody positive, who accepted questionnaire surveys. According to the age, the participants were divided into the sex workers, and in-depth qualitative interviews were conducted from among 12 HIV positive sex workers. HIV antibody positive rate was 0.8% (181), the age of the 181 subjects were (35.83 ± 9.17) years old, 76 cases (42.0%) were sex workers found that regular clients, not consistent use of condoms were the main cause of no condom use. Economic and livelihood factors are important reasons for continuing to engage in sexual services among HIV positive sex workers. HIV positive sex workers still have high risk behaviors including continuing to engage in commercial sexual service and no condom use after knowing their HIV infection status, and the proportion of using drugs in the ≥ 35 years old group was higher than that in < 35 years old group.

Attitudes of Italian heterosexual men and women toward gay men, both HIV positive and negative, are poorly investigated. Italian culture is still extremely conservative and provides limited support to the gay community (e.g., lack of same-sex marriage recognition). Consequently, gay men experience social exclusion and disparities. The present study explores the association between homophobia and closeness with sexual orientation and HIV status. 261 heterosexual Italian men and women were assessed for feelings of closeness and homophobia after reading a vignette where the character was C1: heterosexual and HIV negative; C2: gay and HIV negative; or C3: gay and HIV positive. Experiences of homophobia and closeness varied depending on gender of participant and condition assigned, and higher levels of homophobia were correlated with lower levels of closeness regardless of HIV status. Implications and future directions are discussed.

Full Text Available Opportunistic infections are the leading cause of hospitalization and morbidity in human immunodeficiency virus (HIV positive patients and are the most common cause of death between them. We aimed to measure IgG antibody against EBV viral capsid antigen (EBV-VCA IgG to determine the seroprevalence of this infection in HIV-positive population. A case-control study between September 2011 and October 2012 was conducted in a teaching hospital enrolling 114 HIV-positive patients as case group and 114 healthy individuals as control with similar age and sex. Enzyme-linked immunosurbant assay (ELISA technique was used for determination of EBV-VAC IgG in obtained samples. Of 114 serum samples obtained from HIV-positive patients, 103 (90.4% samples were found positive for EBV-VCA IgG antibody. There was no significant difference in seroprevalence of EBV VCA IgG antibody between patients received antiretroviral therapy and naive patients (91.5% vs. 87.5%, P>0.05. There was no statistically significant difference in EBV-VCA IgG seroprevalence between three groups of CD4+ in HIV positive group. In conclusion current study showed that seroprevalence of EBV in HIV-positive patients is higher than HIV-negative healthy participants; however, administration of HAART and CD4+ lymphocyte count did not reveal a significant effect in seroprevalence of EBV. Due to the significance of this virus in mortality and morbidity and causing certain malignancies in patients with AIDS, these patients are strongly recommended to be tested for this virus.
Full Text Available Background: Microsporidiasis, which is of great concern for immunocompromised patients, is poorly studied in developing countries.Objectives: A study was carried out amongst HIV-positive hospital patients and HIV-negative hospital controls in Ilorin, Nigeria, between January 2009 and July 2010 to determine the prevalence and intensity of Microsporidium spores and the complications associated with their presence.Method: Stool samples from 750 HIV-positive patients and 375 HIV-negative patients were studied using the Chromotrope-2R staining technique. Determination of CD4+ count was performed on the Partec Cyflow SL-3 CD4/8 instrument. Intensity of spores was determined by counting the total number of the spores in a 10 μl stained smear of stool. Images were captured with Phenix Microimage Analysis Software and data obtained were analysed using the Statistical Package for the Social Sciences.Results: The prevalence of Microsporidium isolates amongst the HIV-positive hospital patients was significantly higher (42.4% than amongst the HIV-negative controls (19.2%(p < 0.05. The intensity of microsporidial spores amongst HIV-positive hospital patients was also significantly higher than amongst the controls (p < 0.05. However, the difference in the intensity of spores amongst HIV-positive patients who were on antiretroviral therapy(n = 411 and those who were not (n = 339 was not significant (p = 0.236. Microsporidiasis in HIV infection infection was common amongst patients with with low CD4+ counts, diarrhoea, body rashes and cough.Conclusion: Both the prevalence and intensity of Microsporidiasis are high amongst HIV-positive hospital patients; campaigns to promote awareness, prevention and control are required. Laboratory testing for microsporidia in HIV patients should be performed routinely so as to identify the organism for prompt medical attention.

Conditionally replicating HIV-1 variants that can be switched on and off at will are attractive tools for HIV research. We previously developed a genetically modified HIV-1 variant that replicates exclusively when doxycycline (dox) is administered. The nef gene in this HIV-rtTA variant was replaced with the gene encoding the dox-dependent rtTA transcriptional activator. Because loss of Nef expression compromises virus replication in primary cells and precludes studies on Nef function, we tested different approaches to restore Nef production in HIV-rtTA. Strategies that involved translation via an EMCV or synthetic internal ribosome entry site (IRES) failed because these elements were incompatible with efficient virus replication. Fusion protein approaches with the FMDV 2A peptide and human ubiquitin were successful and resulted in genetically-stable Nef-expressing HIV-rtTA strains that replicate more efficiently in primary T-cells and human immune system (HIS) mice than Nef-deficient variants, thus confirming the positive effect of Nef on in vivo virus replication. - Highlights: • Different approaches to encode additional proteins in the HIV-1 genome were tested. • IRES translation elements are incompatible with efficient HIV-1 replication. • Ubiquitin and 2A fusion protein approaches allow efficient HIV-1 replication. • Doxycycline-controlled HIV-1 variants that encode all viral proteins were developed. • Nef stimulates HIV-rtTA replication in primary cells and human immune system mice.

Responses to the HIV epidemic leading to an increase in the number of residential care facilities for children across sub-Saharan Africa have prompted concerns that large numbers of orphaned children are being placed in institutional care. There is little empirical research into the role that institutions are playing in the provision of care to children affected by HIV in the region. This paper draws on an exploratory study of the provision of residential care for children in the context of the HIV epidemic in South Africa. The analysis characterises the population of children in a small sample of residential care facilities in four provinces, and, after identifying a disproportionate number of HIV-positive children in care, examines the circumstances that led to their admission and the nature of HIV-related interventions in the facilities. The analysis reveals missed opportunities for non-institutional placements for HIV-positive children and identifies important gaps in the HIV prevention, treatment, care, and support interventions within the facilities. The article argues that a global and local preoccupation with orphans as being the children most severely affected by HIV, and as the primary category of children requiring alternative care as a result of the HIV epidemic, may have diverted attention away from the extent to which HIV-positive children populate institutions in South Africa. Furthermore, we suggest that adjustments are required to both decision-making regarding placement of HIV-positive children requiring alternative care and the provision of HIV-related interventions in residential facilities in order to ensure an adequate response to children's health and wellbeing.
Full Text Available HIV disclosure from parent to child is complex and challenging to HIV-positive parents and healthcare professionals. The purpose of the study was to understand the lived experiences of HIV-positive parents and their children during the disclosure process in Kenya. Sixteen HIV-positive parents, seven HIV-positive children, and five HIV-negative children completed semistructured, in-depth interviews. Data were analyzed using the Van Kaam method; NVivo 8 software was used to assist data analysis. We present data on the process of disclosure based on how participants recommended full disclosure be approached to HIV-positive and negative children. Participants recommended disclosure as a process starting at five years with full disclosure delivered at 10 years when the child was capable of understanding the illness, or by 14 years when the child was mature enough to receive the news if full disclosure had not been conducted earlier. Important considerations at the time of full disclosure included the parent’s and/or child’s health statuses, number of infected family members’ illnesses to be disclosed to the child, child’s maturity and understanding level, and the person best suited to deliver full disclosure to the child. The results also revealed it was important to address important life events such as taking a national school examination during disclosure planning and delivery. Recommendations are made for inclusion into HIV disclosure guidelines, manuals, and programs in resource-poor nations with high HIV prevalence.
Full Text Available Results of complex research aimed at the study of dynamics of incidence and mortality caused by human immunodeficiency virus (HIV among children, their medical and social characteristics, problems of social adaptation of rejected children, are presented. It is shown that in the dynamics of HIV incidence among children a steady growth trend is observed, mostly due to children born by HIV positive mothers. The number of HIV positive children due to perinatal transmission, increased by 9 times in 2000–2006. 43,6 per cent of children born by HIV positive mothers had significant deviations in the health status, 21,6 percent of infants were transferred to the 2nd stage of nursing. High level of stillbirths, perinatal and early neonatal mortality of infants born by HIV positive mothers, was observed. Though there is a certain trend of decreasing the number of rejected children both in the general population and among HIV positive mothers, the absolute number of such cases is increasing in the latter group. Children abandoned by their parents in most cases are isolated and do not receive the necessary social and psychological aid.Key words: HIV infection, children, perinatal mortality, social adaptation.

Increased availability of Human Immunodeficiency Virus (HIV) screening test and more public enlightenment have resulted in more people coming forward to access counseling and testing at the HIV counseling and testing centers in Nigeria. Some of the clients however obtained indeterminate and false positive results leading to emotional disturbance and occasionally, dilemma to the attending physician. This article/case series looked at some of these situations and discussed how they were attended to.

Disclosure of Human Immune Virus (HIV) positive status may increase opportunities of obtaining social support, implementation of HIV risk reduction with partners and improving access to treatment and motivate partners for voluntary counseling and testing (VCT). Thus, status disclosure is an issue to be addressed for HIV prevention & treatment. The objective of this study is to determine the magnitude, outcome and determinants of HIV positive status disclosure to sexual partners among women people living with HIV/AIDS at Hawassa University Referral Hospital, Southern Ethiopia. A cross sectional survey was conducted on HIV positive women who were attending ART clinic at Hawassa University Referral Hospital from March to April 2008. Single population proportion formula was used to determine sample size. Convenient sampling was used to recruit patients. Using a structured and pre-tested questionnaire, data were collected through patient interview consecutively until the required number of patients was obtained over one month period. Statistical analysis was done to determine the magnitude and factors associated with HIV positive status disclosure. Overall 85.7% the women had disclosed their HIV positive status to their sexual partners. The common barriers reported for non disclosure of HIV status were fear of abandonment; fear of break-up in relationship and fear of stigma. The negative partner reaction reported by those women who disclosed to sexual partner in this study was found to be high (59.3%). Majority (77.9%) had sexual intercourse in the past 6 month. 9.1% of the women were pregnant since they tested for HIV and significant number of women reported inconsistent use of condom. Being married, being on ART for more than one year and knowing the HIV status of the partner were found to be predictors of HIV positive status disclosure. Even though, the magnitude of HIV positive status disclosure to sexual partner in this study is encouraging, risk behaviors and

The aim of this study was to identify the personality traits of alcohol and human immunodeficiency virus (HIV)-positive patients and to compare them with normal controls. This cross-sectional study included 100 consecutive patients with alcohol dependence and HIV each and a control group of 100 normal cases without any physical or psychiatric illness. A score of 2 or less on the General Health Questionnaire was taken as cutoff, and the participants were included in the study with written informed consent. All participants were assessed with the NEO personality inventory revised and sensation-seeking scale (SSS). There were significant differences among the study group on all the five factors, i.e., neuroticism (N), extraversion (E), conscientiousness (C), openness to experience (O), and agreeableness (A). On factor "N," HIV and alcohol group scored significantly more as compared to normal group. Odds ratio revealed high neuroticism to be a risk factor in alcohol-dependent and HIV cases (P factor "E" as compared to HIV and alcohol cases. High scores on factor "E" and "C" have a protective. Odds ratio found low score of factor "C" as a risk factor; however, "O" did not emerge as a risk factor. The logistic regression revealed that high scores on "N" and "E" and low "A" score had a significant association with alcohol dependence (P < 0.05). Among HIV cases, high score on "N" and "E" and low "C" score emerged significant. Alcohol cases scored significantly more on boredom susceptibility (BS) on SSS as compared to HIV and normal controls. On disinhibition (DIS), HIV cases and alcohol cases scored significantly higher as compared to normal group (P < 0.05). High "N" scores on NEO personality inventory are significantly associated with alcohol dependence and HIV while high scores on "E" and "C" have a protective effect. On SSS, HIV-positive cases are characterized by high DIS scores while alcohol dependence is associated with high scores on BS and DIS.

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

globally women receive HIV testing in pregnancy; however, limited information is available on their experiences of this potentially life-changing event. This study aims to explore women's experiences of receiving a positive HIV test result following antenatal screening. a qualitative, phenomenological approach. two public National Health Service (NHS) hospitals and HIV support organisations. a purposive sampling strategy was used. Thirteen black African women with a positive HIV result, in England, participated. data were collected using in-depth semi-structured interviews. An interpretive phenomenological approach to data analysis was used. the emergent phenomenon was transition and transformation of 'being,' as women accepted HIV as part of their lives. Paired themes support the phenomenon: shock and disbelief; anger and turmoil; stigma and confidentiality issues; acceptance and resilience. Women had extreme reactions to their positive HIV diagnosis, compounded by the cultural belief that they would die. Initial disbelief of the unexpected result developed into sadness at the loss of their old self. Turmoil was evident, as women considered termination of pregnancy, self-harm and suicide. Women felt isolated from others and relationship breakdowns often occurred. Most reported the pervasiveness of stigma, and how this was managed alongside living with HIV. Coping strategies included keeping HIV 'secret' and making their child(ren) the prime focus of life. Growing resilience was apparent with time. this study gives midwives unique understanding of the complexities and major implications for women who tested positive for HIV. Women's experiences resonated with processes of bereavement, providing useful insight into a transitional and transformational period, during which appropriate support can be targeted. midwives are crucial in improving the experience of women when they test HIV positive and to do this they need to be appropriately trained. Midwives need to

Kaposi's sarcoma (KS) is the commonest human immunodeficiency virus (HIV)-related malignancy with its characteristic cutaneous morphological appearance and histopathological features. However, it can be simulated by other co-morbid opportunistic infections and unrelated dermatological conditions. We describe such a case of acroangiodermatitis in an HIV co-infected man, based on exclusion of KS histologically and the absence of human herpesvirus 8, the causative agent of KS.

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

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

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

Full Text Available There has been limited involvement of HIV-negative children in HIV disclosure studies; most studies conducted on the effects of disclosure on children have been with HIV-positive children and HIV-positive mother-child dyads. Seven HIV-positive and five HIV-negative children participated in a larger study conducted to understand the lived experiences of HIV-positive parents and their children during the disclosure process in Kenya. In this study, the experiences of these 12 children after receiving disclosure of their own and their parents’ illnesses respectively are presented. Each child underwent an in-depth qualitative semi-structured digitally recorded interview. The recorded interviews were transcribed and loaded into NVivo8 for phenomenological data analysis. Five themes emerged from the data, indicating that HIV-positive and negative children appear to have differing post-disclosure experiences revolving around acceptance of illness, stigma and discrimination, medication consumption, sexual awareness, and use of coping mechanisms. Following disclosure, HIV-negative children accepted their parents’ illnesses within a few hours to a few weeks; HIV-positive children took weeks to months to accept their own illnesses. HIV-negative children knew of high levels of stigma and discrimination within the community; HIV-positive children reported experiencing indirect incidences of stigma and discrimination. HIV-negative children wanted their parents to take their medications, stay healthy, and pay their school fees so they could have a better life in the future; HIV-positive children viewed medication consumption as an ordeal necessary to keep them healthy. HIV-negative children wanted their parents to speak to them about sexual-related matters; HIV-positive children had lingering questions about relationships, use of condoms, marriage, and childbearing options. All but one preadolescent HIV-positive child had self-identified a person to speak

The aim of this study was to evaluate whether normal controls and human immunodeficiency virus (HIV) patients with and without planning deficits differ on white matter integrity. A total of 34 HIV-positive patients with planning deficits were compared with 13 HIV-positive patients without planning deficits and 19 gender-, age-, and education-matched control subjects. Diffusion tensor imaging (DTI) was performed along 30 noncolinear directions in a 1.5-T scanner. For tract-based spatial statistics analysis, a white matter skeleton was created, and a permutation-based inference with 5000 permutations with a threshold of p < 0.05 was used to identify abnormalities in fractional anisotropy (FA). The median, radial, and axial diffusivities were also projected onto the mean FA skeleton. Compared with controls, HIV-positive patients with planning deficits had decreased FA in bilateral anterior thalamic radiations, bilateral inferior fronto-occiptal fasciculi, genu and splenium of the corpus callosum, bilateral superior longitudinal fascicule, and bilateral uncinate fasciculi. Compared to HIV-positive patients without planning deficits, patients with planning deficits had decreased FA in bilateral anterior thalamic radiations, bilateral inferior fronto-occiptal fasciculi, genu of the corpus callosum, bilateral superior longitudinal fascicule, and right uncinate fascicule. DTI can detect extensive white matter abnormalities in the normal-appearing white matter of HIV-positive patients with planning deficits compared with controls and HIV-positive patients without planning deficits.

Full Text Available OBJECTIVE: Early HIV testing and diagnosis are paramount for increasing treatment initiation among children, necessary for their survival and improved health. However, uptake of pediatric HIV testing is low in high-prevalence areas. We present data on attitudes towards pediatric testing from a nationally representative survey in Zimbabwe. METHODS: All 18-24 year olds and a proportion of 25-49 year olds living in randomly selected enumeration areas from all ten Zimbabwe provinces were invited to self-complete an anonymous questionnaire on a personal digital assistant, and 16,719 people agreed to participate (75% of eligibles. RESULTS: Most people think children can benefit from HIV testing (91%, 81% of people who looked after children know how to access testing for their children and 92% would feel happier if their children were tested. Notably, 42% fear that, if tested, children may be discriminated against by some community members and 28% fear their children are HIV positive. People who fear discrimination against children who have tested for HIV are more likely than their counterparts to perceive their community as stigmatizing against HIV positive people (43% vs. 29%. They are also less likely to report positive attitudes to HIV themselves (49% vs. 74%. Only 28% think it is possible for children HIV-infected at birth to live into adolescence without treatment. Approximately 70% of people (irrespective of whether they are themselves parents think HIV-infected children in their communities can access testing and treatment. CONCLUSIONS: Pediatric HIV testing is the essential gateway to prevention and care services. Our data indicate positive attitudes to testing children, suggesting a conducive environment for increasing uptake of pediatric testing in Zimbabwe. However, there is a need to better understand the barriers to pediatric testing, such as stigma and discrimination, and address the gaps in knowledge regarding HIV/AIDS in children.
Full Text Available HIV rapid diagnostic tests (RDTs combined in an algorithm are the current standard for HIV diagnosis in many sub-Saharan African countries, and extensive laboratory testing has confirmed HIV RDTs have excellent sensitivity and specificity. However, false-positive RDT algorithm results have been reported due to a variety of factors, such as suboptimal quality assurance procedures and inaccurate interpretation of results. We conducted HIV serosurveys in seven sub-Saharan African military populations and recorded the frequency of personnel self-reporting HIV positivity, but subsequently testing HIV-negative during the serosurvey. The frequency of individuals who reported they were HIV-positive but subsequently tested HIV-negative using RDT algorithms ranged from 3.3 to 91.1%, suggesting significant rates of prior false-positive HIV RDT algorithm results, which should be confirmed using biological testing across time in future studies. Simple measures could substantially reduce false-positive results, such as greater adherence to quality assurance guidelines and prevalence-specific HIV testing algorithms as described in the World Health Organization's HIV testing guidelines. Other measures to improve RDT algorithm specificity include classifying individuals with weakly positive test lines as HIV indeterminate and retesting. While expansion of HIV testing in resource-limited countries is critical to identifying HIV-infected individuals for appropriate care and treatment, careful attention to potential causes of false HIV-positive results are needed to prevent the significant medical, psychological, and fiscal costs resulting from individuals receiving a false-positive HIV diagnosis.

Full Text Available The prevalence of HIV-associated neurocognitive disorders (HAND remains high despite effective antiretroviral therapies. Multiple etiologies have been proposed over the last several years to account for this phenomenon, including the neurotoxic effects of antiretrovirals and co-morbid substance abuse; however, no underlying molecular mechanism has been identified. Emerging evidence in several fields has linked the gut to brain diseases, but the effect of the gut on the brain during HIV infection has not been explored. Saliva is the most accessible gut biofluid, and is therefore of great scientific interest for diagnostic and prognostic purposes. This study presents a longitudinal, liquid chromatography-mass spectrometry-based quantitative proteomics study investigating saliva samples taken from 8 HIV-positive (HIV+, 11 -negative (HIV- heroin addicts. In addition, saliva samples were investigated from 11 HIV-, non-heroin addicted healthy controls. In the HIV+ group, 58 proteins were identified that show significant correlations with cognitive scores, implicating disruption of protein quality control pathways by HIV. Notably, only one protein from the HIV- heroin addict cohort showed a significant correlation with cognitive scores, and no proteins correlated with cognitive scores in the healthy control group. In addition, the majority of correlated proteins have been shown to be associated with exosomes, allowing us to propose that the salivary glands and/or oral epithelium may modulate brain function during HIV infection through the release of discrete packets of proteins in the form of exosomes.
Full Text Available HIV exposed, uninfected (HEU infants have been shown to have an increase in overall mortality from infectious causes when compared to HIV unexposed, uninfected (HU infants. This is the case in both resource-rich and resource-limited settings. We explore here the concept that specific types of infectious diseases that are more common among HEU infants could provide clues as to the potential underlying immunological abnormalities. The most commonly reported infections in HEU vs. HU are caused by encapsulated bacteria; this suggests the existence of a less effective humoral (antibody, complement immune response. Decreased transplacental transfer of protective maternal antibodies has been seen consistently among HEU newborns, suggesting that this may indeed be one of the key drivers of their susceptibility to infections with encapsulated bacteria. Reassuringly, HEU humoral response to vaccination appears to be well conserved. While there appears to be an increase in overall incidence of acute viral infections, no specific pattern of acute viral infections has emerged; and while there is evidence of increased chronic viral infection from perinatal transmission of hepatitis C and CMV, no data exist to suggest an increase in adverse outcomes. Thus, no firm conclusions about anti-viral effector mechanisms can be drawn. However, the most unusual of reported infections among the HEU have been opportunistic infections, suggesting the possibility of underlying defects in CD4 helper and overall immune regulatory function. This may relate to the observation that the immunological profile of HEUs indicate more activated T cell profile as well as a more inflammatory innate immune response. However, both of these observations appear temporary, marked in early infancy, but no longer evident later in life. The causes of these changes in early life immune profile are likely multifactorial and may be related to in utero exposure to HIV, but also to increased

Greater understanding of barriers to risk reduction among incarcerated HIV+ persons reentering the community is needed to inform culturally tailored interventions. This qualitative study elicited HIV prevention-related information, motivation and behavioral skills (IMB) needs of 30 incarcerated HIV+ men and women awaiting release from state prison. Unmet information needs included risk questions about viral loads, positive sexual partners, and transmission through casual contact. Social motivational barriers to risk reduction included partner perceptions that prison release increases sexual desirability, partners' negative condom attitudes, and HIV disclosure-related fears of rejection. Personal motivational barriers included depression and strong desires for sex or substance use upon release. Behavioral skills needs included initiating safer behaviors with partners with whom condoms had not been used prior to incarceration, disclosing HIV status, and acquiring clean needles or condoms upon release. Stigma and privacy concerns were prominent prison context barriers to delivering HIV prevention services during incarceration.
Full Text Available Background. Early entry into HIV care is low in Sub-Saharan Africa. In Rakai, about a third (31.5% of HIV-positive clients who knew their serostatus did not enroll into free care services. This qualitative study explored barriers to entry into care from HIV-positive clients who had never enrolled in care and HIV care providers. Methods. We conducted 48 in-depth interviews among HIV-infected individuals aged 15–49 years, who had not entered care within six months of result receipt and referral for free care. Key-informant interviews were conducted with 12 providers. Interviews were audio-recorded and transcripts subjected to thematic content analysis based on the health belief model. Results. Barriers to using HIV care included fear of stigma and HIV disclosure, women’s lack of support from male partners, demanding work schedules, and high transport costs. Programmatic barriers included fear of antiretroviral drug side effects, long waiting and travel times, and inadequate staff respect for patients. Denial of HIV status, belief in spiritual healing, and absence of AIDS symptoms were also barriers. Conclusion. Targeted interventions to combat stigma, strengthen couple counseling and health education programs, address gender inequalities, and implement patient-friendly and flexible clinic service hours are needed to address barriers to HIV care.

This paper examines cultural and social meanings associated with semen, along with related issues of unprotected receptive anal intercourse, HIV seroconversion, treatment optimism and viraemia. The findings are derived from qualitative interviews conducted with 12 HIV-positive young gay men and 12 HIV-negative counterparts who participated in a prospective cohort study in Vancouver, Canada. Focussing on the narratives of young gay men, the analysis reveals a diverse range of knowledge, values and functions of semen, especially in relation to its exchange. Beliefs about semen appeared to differ by HIV serostatus and were linked with intimacy, identity and pleasure, particularly among the HIV-positive men. Against dominant representations of semen in relation to issues of loss, anxiety and infertility, this unique study sheds much needed light on its role within the cultural construction of sexuality among gay men. As such, these narratives are of direct importance to primary and secondary HIV prevention, including condom promotion and the development of rectal microbicides.

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

Though Black and Hispanic men who have sex with men (MSM) are at an increased risk for HIV, few HIV risk reduction interventions that target HIV-positive MSM, and even fewer that use technology, have been designed to target these groups. Despite similar rates of social media and technology use across racial/ethnic groups, online engagement of minority MSM for HIV prevention efforts is low. Since minority MSM tend to have less representation in online HIV prevention studies, the goals of this online anonymous study of HIV-positive gay-identified men were to test the feasibility of conducting targeted recruitment by race/ethnicity and sexual orientation, to assess technology and social media use, and to assess global HIV transmission risk. In 2011, an anonymous online survey was conducted among 463 members of an HIV-positive personals website. Emails were sent to a subset of HIV-positive male members who self-identified as gay. While 57 % were White, substantial proportions of participants were Black (20 %) or Hispanic (18 %). Median age was 46 (range 18-79). Men who reported using 3 or more websites or apps to meet sex partners were significantly more likely to report anal intercourse (AOR 4.43, p social media use, and sexual risk among a diverse sample of HIV-positive gay men. Efficacy trials of technology-based HIV prevention interventions targeting high-risk minority HIV-positive MSM are warranted.

To determine the prevalence and factors associated with unintended pregnancy among HIV-positive pregnant women in Enugu, southeast Nigeria. A questionnaire-based cross-sectional study was performed of HIV-positive pregnant women receiving prenatal care at two tertiary health institutions in Enugu between March 1 and August 31, 2012. The women were interviewed with a pretested questionnaire. Overall, 180 HIV-positive pregnant women were recruited, 67 (37.2%) of whom declared that their pregnancy was unintended. Overall, 174 (96.7%) patients were receiving antiretroviral therapy and 99 (55.0%) had future fertility intensions. Participants with regular partners (married or cohabiting) had a significantly higher rate of unintended pregnancy than those with unstable partners (40.3%, n=64/159 vs 14.3%, n=3/21 P=0.029). Age, parity, educational level, and current treatment with antiretroviral therapy did not significantly affect the prevalence of unintended pregnancy. A substantial number of HIV-positive pregnant women declared their pregnancies to be unintended. Modern contraceptives should be made readily available and accessible to HIV-positive women to help eliminate mother-to-child transmission of HIV and subsequent new pediatric HIV infections.

The spread of HIV-1 infection among women of childbearing age has led to increasing numbers of children at risk of vertical transmission. This study aimed to assess child outcomes among HIV-positive (n=19) and AIDS (n=22) mothers from Central West Brazil. CD4(+) T-cell counts (FACScount, BD) and viral loads (HIV-1 RT-PCR, Amplicor HIV-1 Monitor Roche) were assessed at delivery and during the first 6 months of life. Heteroduplex mobility assay identified env and gag HIV-1 subtypes. Frequencies and medians were calculated. HIV-positive and AIDS mothers did not differ with regard to age, antiretroviral prophylaxis, parity and viral load. AIDS mothers had lower CD4(+) T-cell counts. One vertical transmission and a neonatal death were observed. Gestational age, gender and oral zidovudine prophylaxis were similar regardless of maternal clinical status. Infants born to AIDS mothers had lower birthweight and shorter time to seroreversion. Eight infants were lost to follow-up, and two were breastfed due to delayed maternal diagnosis. HIV-1 B(env)/B(gag) subtype were 75.6%; discordant B(env)/F(gag) were 12.2%. Exposed uninfected infants born to AIDS mothers with lower CD4(+) T-cell counts seroreverted earlier than infants born to asymptomatic HIV-positive mothers. It is possible that maternal immunological status may impact on the time to seroreversion.

Full Text Available Background: Sexually transmitted infections (STIs remain an important public health issue in sub-Saharan Africa. STIs in HIV-positive women are associated not only with gynecological complications but with increased risk of HIV transmission to HIV-negative partners and newborns. Aims: The aims of this study are to determine the prevalence of chlamydia (CT and gonorrhea (GC and examine the demographic characteristics and risk behaviors associated with these STIs in a group of HIV-positive women in Lusaka, Zambia. Settings and Design: Cross-sectional study of a sample of HIV-infected women enrolled in two large studies conducted in urban Lusaka, Zambia. Materials and Methods: HIV-seropositive women (n = 292 were assessed for demographic and behavioral risk factors and tested for CT and GC. Univariate analysis was used to determine the demographic characteristics and risk behaviors associated with having CT or GC. Results: The identified prevalence of CT was 1% and of GC was 1.4%. There was an association of CT/GC with the use of alcohol before sex (OR = 9.I, CI = 0.59-0.15, P = 0.03. Conclusions: Rates of CT and GC are described in this sample of HIV-positive women. While being in HIV care may serve to increase medical care and condom use, alcohol use should be addressed in this population.

In a cross-sectional study of 3,424 women from urban (Dar es Salaam) and rural (Pwani, Mwanza, and Mtwara) Tanzania, conducted in 2008-2009, we investigated risk factors for human immunodeficiency virus (HIV) and the association between different measures of human papillomavirus (HPV) and HIV positivity. Study participants were interviewed about socio-demographic and reproductive factors and sexual behavior. Blood samples were tested for HIV, and the women underwent a gynecological examination. HPV status was determined by Hybrid Capture 2, and HPV genotyping was performed using the LiPA Extra test. Multivariable logistic regression models estimating odds ratios (OR) and 95% confidence intervals (CI) were used. The overall HIV prevalence was 10.2%. HIV-positive women were more likely to have high-risk (HR) HPV detected (OR = 4.11; 95% CI: 3.23-5.24) and clinically visible genital warts (OR = 4.37; 95% CI: 1.81-10.5). Other risk factors included age, place of residence, education, number of births, lifetime number of sexual partners, and time in present relationship. HIV risk factors among urban and rural women and among HPV-positive and HPV-negative women were similar. HPV vaccination may provide some protection against HIV infection in Tanzania, but focus must still be on preventing established risk factors for HIV.

As HIV/AIDS prevalence rises in Eastern Europe, assessment of local epidemics in the bordering Central European region, especially South Eastern Europe, is vital in order to meet treatment and prevention needs. Understanding current medical and social needs and barriers to care experienced by HIV-positive patients in these regions may provide insight into how to best respond to the local epidemics, increase patients' access to treatment, and reduce loss to follow-up. This study assesses the patient characteristics, barriers to care, and current medical and social needs of HIV-positive patients in Albania. Semi-structured interviews were used in this cross-sectional study. We interviewed 79 of 85 patients (93% response rate) followed at the University Hospital Center of Tirana (UHCT) HIV/AIDS Ambulatory Clinic, which represented the majority of patients under HIV care in Albania during 2009. The local HIV epidemic seems to be comprised mainly of heterosexual men who have spent an average of 3.6 years abroad. The vast majority of patients under care at UHCT HIV/AIDS Ambulatory Clinic had experienced barriers to care associated with social stigma (97.4%), lack of knowledge of HIV medical care (76.6%), and medical provider's lack of knowledge of HIV (70.9%). Social needs of the patients were also overwhelmingly unmet (90.0-95.7%). In addressing HIV/AIDS in Albania, it will be crucial to educate the healthcare sector in ways to identify and address barriers to care and current medical and social needs of HIV-positive patients.

To describe the ethical aspects involved in the dental care provided to patients who are HIV-positive or who have AIDS. Literature review (textbooks and MEDLINE and LILACS databases), with an emphasis on the work developed at the School of Dentistry, Federal University of Minas Gerais, Brazil. We examined the social representation of AIDS, the risk of HIV infection during office visits, the refusal to provide care, referral to other professionals without justification, special charges and office visit hours for HIV-positive patients, and the confidentiality of the serological status of the patient. There is still prejudice and ignorance about the risk of HIV and AIDS infection, on the part of dental surgeons and of patients. An educational project should be undertaken at dental offices and at universities that train new professionals. In addition, the role of national and regional professional associations in providing information concerning ethical aspects involved in the care of HIV/AIDS patients should be reinforced.

Background. The Duffy-null trait and ethnic netropenia are both highly prevalent in Africa. The influence of pre-seroconversion levels of peripheral blood cell counts (PBCs) on the risk of acquiring human immunodeficiency virus (HIV)–1 infection among Africans is unknown. Methods. The triangular relationship among pre-seroconversion PBC counts, host genotypes, and risk of HIV acquisition was determined in a prospective cohort of black South African high-risk female sex workers. Twenty-seven women had seroconversion during follow-up, and 115 remained HIV negative for 2 years, despite engaging in high-risk activity. Results. Pre-seroconversion neutrophil counts in women who subsequently had seroconversion were significantly lower, whereas platelet counts were higher, compared with those who remained HIV negative. Comprising 27% of the cohort, subjects with pre-seroconversion neutrophil counts of C) was significantly associated with neutrophil counts (P = 7.9 × 10−11). DARC −46C/C results in loss of DARC expression on erthyrocytes (Duffy-null) and resistance to Plasmodium vivax malaria, and in our cohort, only subjects with this genotype had pre-seroconversion neutrophil counts of <2500 cells/mm3. The risk of acquiring HIV infection was ∼3-fold greater in those with the trait of Duffy-null–associated low neutrophil counts, compared with all other study participants. Conclusions. Pre-seroconversion neutrophil and platelet counts influence risk of HIV infection. The trait of Duffy-null–associated low neutrophil counts influences HIV susceptibility. Because of the high prevalence of this trait among persons of African ancestry, it may contribute to the dynamics of the HIV epidemic in Africa. PMID:21507922

HIV develops drug resistance at a high rate under drug selection pressure. Resistance tests are recommended to help physicians optimize antiretroviral drug therapies. For this purpose, genotypic and phenotypic tests have been developed. In order to propose a new phenotypic test that will be less laborious, expensive, and time consuming than the standard ones, a new procedure to measure HIV-1 protease susceptibility to protease inhibitor (PIs) in Saccharomyces cerevisiae yeast cells was developed. This procedure is based on HIV-1 protease expression in yeast. While the viral protein induces yeast cell death, its inhibition by PIs in the culture medium allows the cell to grow in a dose-dependent manner. In a comparative study of standard genotypic analysis vs. yeast cell-based phenotypic tests, performed on HIV-1 protease coding DNA in 17 different plasma samples from infected individuals, a clear match was found between the results obtained using the two technologies. This suggests that the yeast-based procedure is at least as accurate as standard genotypic test in defining susceptibility to protease inhibitors. This encouraging result should be the basis for large-scale validation of the new phenotypic resistance test. Copyright © 2013 Elsevier B.V. All rights reserved.

Throughout the 1990s, many villagers in rural China were infected with HIV through commercial plasma/blood donation. These former plasma/blood donors (FPDs) experienced many HIV-related stressors. This study tested a cognitive appraisal model of stress and coping in a sample of HIV-positive adult FPDs. Participants (N = 207) from multiple villages completed a battery of questionnaires assessing HIV-related stress, HIV symptoms, cognitive appraisal, coping behaviors, and psychological distress. Participants reported high levels of HIV-related stress, depression, and anxiety. In a structural equation model, greater HIV-related stress, HIV symptoms, and threat appraisal were directly associated with psychological distress. HIV-related stress was also indirectly associated with psychological distress through threat appraisal. In a second model, coping was found to mediate the relationship between challenge appraisal and psychological distress. Results support the utility of cognitive appraisal theory. Stress management interventions targeting HIV-positive FPDs in China are indicated. PMID:19127424

Human immunodeficiency virus 2 (HIV-2) is found predominantly in West Africa. It is not unlikely, however, that HIV-2 may also be found in South Africa, due to the influx of immigrants into this country. It is important to distinguish between HIV-1 and HIV-2 since the clinical courses and treatment responses of these viruses are different. Routine serological methods for diagnosing HIV do not differentiate between HIV-1 and -2 infections, while rapid tests, viral load quantification and PCR are HIV-type--specific. The objective of this study was to describe the seroprevalence and molecular epidemiology of HIV-2 in KwaZulu-Natal, one of the regions with the highest HIV prevalence in the world and home of the two largest harbors in South Africa. HIV-1 positive samples were screened for antibodies against HIV-2, using a rapid test. The confirmation of HIV-2 positive samples was done by PCR. Of the 2,123 samples screened, 319 (15%) were identified as positive by the rapid test. None of these samples were confirmed positive by PCR. To explore this discrepancy in the results, a subset (n = 52) of the rapid HIV-2 positive samples was subjected to Western blotting. Thirty-seven (71%) of these were positive, yielding an overall HIV-2 seroprevalence of 10.6%. Three out of 28 (10.7%) Western blot positive samples were positive by a Pepti-LAV assay. This discrepancy between serological and molecular confirmation may be attributed to non-specific or cross-reacting antibodies. The use of rapid tests and Western blots for HIV-2 diagnosis in South Africa should be interpreted with caution. © 2013 Wiley Periodicals, Inc.
Neurons are one of the few cell types in the human body that do not support HIV type-1 (HIV-1) replication. Although the lack of key receptors is a major obstacle to infection, studies suggest that additional functions inhibit virus replication to explain the exquisite resistance of neurons to HIV-1. However, specific neuronal factors that may explain this resistance remain to be discovered. In a screen for antiviral factors using a fibroblast line chemically mutagenized and selected for resistance to retroviral infection, we recently identified induction of rat FEZ1 (fasciculation and elongation protein zeta-1), a brain-specific protein, as the cause of this resistance. When exogenously expressed in nonneuronal cell lines rat FEZ1 blocked nuclear entry of retroviral DNA. Here, we demonstrate that among human brain cells, neurons naturally express high levels of FEZ1 compared to astrocytes or microglia cells and are correspondingly less susceptible to infection with pseudotyped HIV-1 that bypasses receptor-mediated viral entry. Demonstrating that endogenous FEZ1 was functionally important in the resistance of neurons to HIV-1 infection, siRNA-mediated knockdown of endogenous FEZ1 increased the infectivity of neurons while sensitive brain cell types like microglia became more resistant upon FEZ1 overexpression. In addition, FEZ1 expression was not induced in response to IFN treatment. As such, in contrast to other widely expressed, IFN-inducible antiviral factors, FEZ1 appears to represent a unique neuron-specific determinant of cellular susceptibility to infection in a cell type that is naturally resistant to HIV-1.

This cross-sectional study sought to determine factors associated with sterilization among HIV-positive US women. HIV-positive women aged 18-45 completed an Audio Computer Assisted Self Interview (ACASI) questionnaire. Chi-square tests and multivariable logistic regression evaluated factors associated with sterilization. The median age of the 187 participants was 37, the majority had at least a high school education, and 88% were African American. Nearly a quarter (22%) of women had undergone sterilization at an average age of 25; of these women, 71% cited their HIV-positive status as an important factor in deciding to have a tubal ligation, 22% expressed desire for future children, 32% reported sterilization regret, and 20% reported feeling pressure to undergo sterilization. In multivariable analysis, factors significantly associated with sterilization included non-African American race, no desire for future pregnancy, having heard of any birth control methods making it harder to get pregnant in the future, belief that women should take a break from hormonal methods every few years, and having had a child born with HIV. While almost a quarter of this HIV-positive group was sterilized, many during the height of the early HIV epidemic, a large proportion of sterilized women expressed sterilization regret. Counseling messages for sterilized HIV-positive women should be sensitive to the fact that women may have regret regarding a decision that, in some cases, may historically have been part of provider recommendations to prevent vertical transmission of HIV. Improved knowledge about contraceptive options such as the IUD and implant is needed among HIV-positive women.

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

Full Text Available Abstract Background Cervical Cancer (CC is the number one cancer among women in sub-Saharan Africa. Although CC is preventable, most women in developing countries do not have access to screening. Methods This cross-sectional study was conducted to determine the prevalence and risk factors for cervical lesions using visual inspection with acetic acid (VIA among 112 HIV positive and 161 negative women aged 18–69 years. Results The presence of cervical lesions was greater among HIV positive (22.9% than HIV negative women (5.7%; p < 0.0001. In logistic models, the risk of cervical lesions among HIV positive women was 5.24 times higher when adjusted by age (OR 5.24, CI 2.31–11.88, and 4.06 times higher in a full model (OR 4.06, CI 1.61–10.25, than among HIV negative women. In the age-adjusted model women who had ≥2 lifetime sexual partners were 3 times more likely (OR 3.00, CI 1.02–8.85 to have cervical lesions compared to women with one lifetime partner and the odds of cervical lesions among women with a history of STIs were 2.16 greater (OR 2.16, CI 1.04–4.50 than among women with no previous STI. In the fully adjusted model women who had a previous cervical exam were 2.5 times more likely (OR 2.53, CI 1.06–6.05 to have cervical lesions than women who had not. Conclusions The high prevalence of HIV infection and the strong association between HIV and cervical lesions highlight the need for substantial scale-up of cervical screening to decrease the rate of CC in Swaziland.

Legal actions have been launched in Alabama and Mississippi to address living conditions and medical care of HIV-positive prisoners in state prisons. These were the only two states to allow complete segregation of HIV-positive prisoners in state prisons into the 1990s. The two cases highlight the ways in which the courts have been involved in supervising prison conditions in the United States.

HIV testing is known to be stressful, however the impact of false positive HIV results on individuals is not well documented. This is a series of four case who developed psychological difficulties and psychiatric morbidities after being informed they had been misdiagnosed with HIV-positive status. We look into documented cases of misdiagnosis and potential risks of misdiagnosis. The case series highlights the implications a false diagnosis HIV-positive status can have, even when the diagnosis is rectified. Impact of misdiagnosis of HIV can lead to psychosocial difficulties and psychiatric morbidity, have public health and epidemiological implications and can lead to medico-legal conflict. This further reiterates the importance of HIV testing carried out ethically and sensitively, and in line with guidelines, respecting confidentiality and consent, and offering counselling pre-test and post-test, being mindful of the reality of erroneous and false positive HIV test results. The implications of misdiagnosis are for the individual, their partners and social contacts, as well as for the community.

On the other hand, it is a major mode of vertical HIV transmission. In developing countries like Ethiopia, HIV positive mothers are advised to continue breastfeeding up to 12 months. But there is scarce literature regarding the mothers' adherence to continued breastfeeding recommendations. Therefore, the objective of this study is to assess HIV positive mothers' adherence to the infant feeding recommendations of the new World Health Organization (WHO guidelines for HIV-exposed infants aged ≥6 months. Methods: A cross-sectional study was conducted in health institutions with antiretroviral therapy and prevention of mother to child transmission facilities in Sidama Zone, Southern Ethiopia. Health institutions were considered as clusters and cluster sampling technique was employed. A total of 184 HIV positive mothers with their infants registered at respective health institutions were recruited and assessed for their infant breastfeeding practices. Descriptive statistics (frequency, mean, median, and standard deviation were computed to describe the breastfeeding practices of HIV positive mothers. Result: Almost all (181 [98.4%] of the HIV-exposed infants were “ever breastfed”. Among those mothers who had ever breastfed, 158 (87.3% initiated breastfeeding within an hour of delivery and 157 (85.8% had fed their babies colostrum while 31 (16.8% gave prelacteal food to their infants.

Despite abolishing the policy of giving the results of the serological test as a way to promote blood donation, and also after improving the predonation questionnaire, we still have a high prevalence of HIV positive blood donors. In this paper we try to analyze, interviewing the HIV positive blood donors in our Counselling Clinic from January 1995 to December 1996, why they were accepted. We asked the HIV positive blood donors to fill a form with the following questions: identification, kind and frequency of blood donation, HIV high risk behaviour, awareness of predonation serological status, willingness toward blood donation, awareness of how dangerous the transfusion of HIV contaminated blood is. For the screening we used Abbott HIV1/HIV 3rd generation plus EIA, test and HIV-1 Western Blot Cambridge, Biotest, Worcester MA, for confirmatory assays. During the evaluation period, 53,338 blood donors were attended, 130 (0.24%) were confirmed HIV positive. Only 18/130 (13.84%) assisted to the Counselling Clinic. The mean age was 33.27 +/- 5.35 years old, all males, 15 singles and 3 with stable couples. 6/18 (33.33%) could have been discarded because of physical appearance or because of theirs jobs. "Voluntary Donation" was higher than in the control group (p = 0.0001). Homo/bisexual and promiscuous behaviour (p = 0.0003) were the predominant high risk factors, in this group 55.55% had more than one risk factor. The association with HBV and syphilis was high (p = 0.0001 and p = 0.0005). 5/18 (27.77%) knew they were HIV positive; 3/18 (16.66%) had the suspicion they were HIV positive and 10/18 (55.55%) did not know it; however the risk factors were the same in those groups. In the knew/suspicion group the main reasons for blood donation were: Performing the test once more, 6; failure in the predonation questionnaire, 1; family pressure, 1. In the group that ignored their HIV positivity: ignorance of belonging to a high-risk group, 6; lack of confidence in the

The prevalence of HIV-associated neurocognitive disorders (HAND) remains high despite effective antiretroviral therapies. Multiple etiologies have been proposed over the last few years to account for this phenomenon, including the neurotoxic effects of antiretrovirals and co-morbid substance abuse. However, no underlying molecular mechanism has been identified. Emerging evidence in several fields has linked the gut to brain diseases, but the effect of the gut on the brain during HIV infection has not been explored. Saliva is the most accessible gut biofluid, and is therefore of great scientific interest for diagnostic and prognostic purposes. This study presents a longitudinal, liquid chromatography-mass spectrometry-based quantitative proteomics study investigating saliva samples taken from 8 HIV-positive (HIV+) and 11 -negative (HIV-) heroin addicts. In the HIV+ group, 58 proteins were identified that show significant correlations with cognitive scores and that implicate disruption of protein quality control pathways by HIV. Notably, no proteins from the HIV- heroin addict cohort showed significant correlations with cognitive scores. In addition, the majority of correlated proteins have been shown to be associated with exosomes, allowing us to propose that the salivary glands and/or oral epithelium may modulate brain function during HIV infection through the release of discrete packets of proteins in the form of exosomes.

Full Text Available Introduction: Candida albicans is the most frequently isolated yeast from the oral cavity of HIV-infected individuals. The use of fluconazole has increased the number of resistant or less-sensitive Candida species different from C. albicans, to this antifungal agent. Objective: To establish the Candida species present in the oral cavity of HIV-infected individuals at a hospital in Cali (Colombia, their population densities, and the susceptibility to fluconazole of species different from C. albicans. Materials and methods: Samples were cultured in CHROMagar Candida and the number of colony forming units (CFU was counted. Yeast identification was done with API 20C Aux, and the susceptibility tests to fluconazole, by Etest. Results: 230 patients were studied, and 202 isolates were obtained: 106 single and 96 mixed. C. albicans predominated, followed by C. dubliniensis and C. glabrata. Candida species other than C. albicans predominated in counts lower than 400 CFU/mL. Susceptibility study to fluconazole of species different from C. albicans showed that 14 (40 % of the isolates were susceptible dose-dependent and 7 (20 %, resistant. Conclusion: In the studied population, the oral cavity was colonized by non-wild type isolates that represent a risk for the development of oropharyngeal candidiasis resistant to fluconazole treatment.

Comparative analyses were conducted for several sub-samples. Analyses revealed that across the entire sample, HIV-positive women appeared to engage in more risky behaviors than HIV-negative women (p< .01); however, as a group, pregnant HIV-positive women reported safer behaviors than non-pregnant HIV-positive women (p<.01). Women from all groups were generally knowledgeable about the risk of HIV transmission through dirty needles and mother to child. However, inaccurate information about transmission through supernatural means and mosquitoes was very common. These results suggest that knowledge and education are negatively associated with HIV status in this sample. Addressing gaps in knowledge and behavior and reducing the risky behaviors of HIV-positive individuals are important directions for future programs.

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

Despite the high specificity of fourth-generation enzyme immunoassays (4th-gen-EIA) for screening during HIV diagnosis, their positive predictive value is low in populations with low HIV prevalence. Thus, screening should be optimized to reduce false positive results. The influence of sample cutoff (S/CO) values by a 4th-gen-EIA with the false positive rate during the routine HIV diagnosis in a low HIV prevalence population was evaluated. A total of 30,201 sera were tested for HIV diagnosis using Abbott Architect® HIV-Ag/Ab-Combo 4th-gen-EIA at a hospital in Spain during 17 months. Architect S/CO values were recorded, comparing the HIV-1 positive results following Architect interpretation (S/CO≥1) with the final HIV-1 diagnosis by confirmatory tests (line immunoassay, LIA and/or nucleic acid test, NAT). ROC curve was also performed. Among the 30,201 HIV performed tests, 256 (0.85%) were positive according to Architect interpretation (S/CO≥1) but only 229 (0.76%) were definitively HIV-1 positive after LIA and/or NAT. Thus, 27 (10.5%) of 256 samples with S/CO≥1 by Architect were false positive diagnose. The false positive rate decreased when the S/CO ratio increased. All 19 samples with S/CO ≤10 were false positives and all 220 with S/CO>50 true HIV-positives. The optimal S/CO cutoff value provided by ROC curves was 32.7. No false negative results were found. We show that very low S/CO values during HIV-1 screening using Architect can result HIV negative after confirmation by LIA and NAT. The false positive rate is reduced when S/CO increases.

This study was carried out to determine the frequency of false-positive results during serological screening for the presence of antibodies against HIV-I/2 in blood banks. A cross-sectional study was conducted from January-December 1999 as screening of voluntary non-renumerated blood donor pool for HIV in the public sector blood banks, in all the six divisions of Balochistan. 5000 subjects were screened for the presence of antibodies against HIV-I/ 2. The subjects were all males between the age group 18-50 years, attending the public sector blood banks as non-renumerated blood donors. Strategy 1 was adopted for initial screening. Strategy II and III were observed in retesting on ELISA, as recommended by UNAIDS/WHO for blood banks. Out of 5000 subjects, 48 (0.96%) were positive for HIV-I/2 on Strategy I, 37 (77% of 48) met the criteria of false positive, while only 11 (0.22% of 5000) were found to be true positive. In blood banks, screening for HIV antibodies is performed for intervention of the positive donations. UNAIDS / WHO Strategy-I is observed on a smaller workload blood banks where donations are less than 20 per day. A high rate of false positive results in serological HIV screening on Strategy-I depicts that the test is highly sensitive but not highly specific. Labeling someone with HIV positive, when actually he is not, forces the health authorities to find other ways of HIV screening in blood banks, which should be much more specific and therefore reliable.

Recent reports showed a high frequency of osteopenia/osteoporosis in HIV-infected subjects. Mechanism on the basis of this alteration is still unclear, as the direct effect of virus or of antiretroviral drugs. One hundred sixty-one consecutive HIV-infected outpatients aged 30-50 years, both naive and HAART-treated for >1 year, were included. An interview questionnaire was performed to establish prior pathological, toxic, epidemiological histories, medications intake, physical activity and eating habits. Blood and urinary tests were checked to exclude concomitant diseases, as were markers of bone metabolism and vitamin D3-metabolites. Each subject underwent to a lumbar spine and left hipbone mineral density by DEXA, using WHO criteria for diagnosis of osteopenia/osteoporosis. Radiologist was unaware if the subject was receiving HAART or not. For groups' homogeneity Chi-square, Fisher's exact and Student's t tests were used. Logistic regression analysis was used to find predictors of osteopenia/osteoporosis and linear regression model to find differences in bone mass density. The demographic characteristics of the 48 naive subjects and the 113 on HAART were comparable. Eighty subjects (49.7%) showed osteopenia/osteoporosis: 22 (45.8%) naive and 58 (51.3%) on HAART (P = 0.46). Independent predictors of osteopenia/osteoporosis were female gender (OR: 3.02, 95% CI: 1.26-7.25, P = 0.01 vs. male), older age (OR: 1.10, 95% CI: 1.01-1.20, P = 0.03, for each additional year), low body mass index (OR: 0.78, 95% CI: 0.68-0.91, P = 0.001 for each additional unit) and higher HIV-RNA levels at DEXA (OR: 1.97, 95% CI: 1.16-3.34, P = 0.01 for each additional Log(10)), whereas the use of HAART (OR: 2.61, 95% CI: 0.66-10.27, P = 0.17 vs. naive) and the alterations of markers of bone metabolism were not significantly related to osteopenia/osteoporosis. Similar findings were obtained using linear regression model analysis. HIV-infected subjects have a high frequency of osteopenia

HER2 amplification/overexpression accounts for aggressive clinical features of HER2 positive breast cancer. Epigenetic changes including DNA methylation, histone modifications and ncRNAs/miRNAs are associated with regulation of DNA chromatin and specifically, gene transcription. Hence, these produce eminent effects upon proto-oncogenes, tumor-suppressors and key cancer-regulatory signaling pathways. Understanding of epigenomic regulation of HER2 overexpression and signaling may help uncover the unmatchable physiology of HER2 gene/protein. Moreover, this may also aid in resolving the major issue of resistance-development towards HER2 targeted agents (trastuzumab and lapatinib), since epigenetic alterations are important therapeutic markers and modulate the response towards HER2 targeted therapy. Therefore, in this review the information regarding various epigenetic markers implicated in HER2 positive breast cancer susceptibility and therapeutic-strategies has been compiled.

Most studies have indicated that friends or families of choice provide more support to HIV-positive men who have sex with men (MSM) than members of the family of origin. The creation of families of choice by MSM has been viewed as a means of creating a support system in the absence of traditional family. The purpose of this study is to explore if HIV-positive MSM believe family of origin are important. Data was drawn from a qualitative study of HIV disclosure to family. Responses to the question “How important is family to you?” are explored. Results suggest that for many HIV-positive MSM relationships with family of origin are very important. While not definitive, data to be presented are provocative and challenge notions of the significance of family of origin to marginalized populations. PMID:21745231

Fertility decisions among people living with HIV/AIDS (PLWHA) are complicated by disease progression, the health of their existing children and possible antiretroviral therapy (ART) use, among other factors. Using a sample of HIV-positive women (n = 353) and men (n = 299) from Nigeria and Zambia and their healthcare providers (n = 179), we examined attitudes towards childbearing and abortion by HIV-positive women. To measure childbearing and abortion attitudes, we used individual indicators and a composite measure (an index). Support for an HIV-positive woman to have a child was greatest if she was nulliparous or if her desire to have a child was not conditioned on parity and lowest if she already had an HIV-positive child. Such support was found to be lower among HIV-positive women than among HIV-positive men, both of which were lower than reported support from their healthcare providers. There was wider variation in support for abortion depending on the measure than there was for support for childbearing. Half of all respondents indicated no or low support for abortion on the index measure while between 2 and 4 in 10 respondents were supportive of HIV-positive women being able to terminate a pregnancy. The overall low levels of support for abortion indicate that most respondents did not see HIV as a medical condition which justifies abortion. Respondents in Nigeria and those who live in urban areas were more likely to support HIV-positive women's childbearing. About a fifth of HIV-positive respondents reported being counselled to end childbearing after their diagnosis. In summary, respondents from both Nigeria and Zambia demonstrate tempered support of (continued) childbearing among HIV-positive women while anti-abortion attitudes remain strong. Access to ART did not impart a strong effect on these attitudes. Therefore, pronatalist attitudes remain in place in the face of HIV infection.

Syphilis is an infection frequently seen with HIV, and European guidelines on the management of syphilis suggest that HIV-infected patients may have an increased risk of early neurological involvement, sometimes asymptomatic. Recent study shows a relationship between neurosyphilis and cerebrospinal fluid (CSF) HIV viral load (VL), which in turn may be associated with subsequent neurocognitive decline. The aim of the study was estimation of the frequency of neurosyphilis among HIV-positive patients with early syphilis. The study included all patients diagnosed with early syphilis who had lumbar puncture performed in the years 2008-2012. Analysis included CSF parameters (serology, mononuclear cells, protein, glucose, chloride and lactate levels), CD4 count, serum VL and highly active antiretroviral therapy (HAART). Diagnosis of neurosyphilis was confirmed by CSF serology [positive fluorescent treponemal antibody and/or Venereal Disease Research Laboratory (VDRL) test(s)] and increased number of mononuclear cells. Statistical analysis included χ(2) tests with an accepted significance level of P 1000 HIV-1 RNA copies/mL (P = 0.0451), as well as HAART treatment (P = 0.0328). The proportion of confirmed neurosyphilis cases, also in patients with low serum VDRL titres, was very high. Considering the high proportion of patients who objected to having LP performed in the absence of neurological symptoms and the risk associated with this procedure, it may be preferable to use treatments with good CNS penetration in all HIV-positive patients with early syphilis. © 2015 British HIV Association.

Among 101 patients with testicular cancer referred to the Department of Oncology ONB, Finsen Institute, four were proven HIV-positive before admission. Three of these patients were treated with cisplatin, 4-epi-podophyllotoxin (VP-16, Etoposide) and bleomycin. One patient with stage I of the testicular cancer was observed, after orchiectomy, without medical antineoplastic treatment. In the HIV-positive patients treated with cytotoxic drugs, leucopenia was seen after one (8%), fever after three (23%) and thrombocytopenia after two (15%) courses. Amongst patients not proven HIV-positive leucopenia, fever and thrombocytopenia were seen after 11 (9%), 21 (18%) and 27 (29%) courses. Two patients had stage II and two patients stage III of the HIV infection prior to treatment. The clinical stage of the disease did not change during the course of chemotherapy. We suggest that HIV-positive patients (stage II and III) with germ cell tumours should be treated with the same aggressive chemotherapy as given to other patients, not proven HIV-positive.

Since the primary mode of HIV transmission in sub-Saharan Africa is heterosexual, research focusing on the sexual behaviour of men who have sex with men (MSM) is scant. Currently it is unknown how many people living with HIV in South Africa are MSM and there is even less known about the stigmatisation and discrimination of HIV-positive MSM. The current study examined the stigma and discrimination experiences of MSM living with HIV/AIDS in South Africa. Anonymous venue-based surveys were collected from 92 HIV-positive MSM and 330 HIV-positive men who only reported sex with women (MSW). Internalised stigma was high among all HIV-positive men who took part in the survey, with 56% of men reporting that they concealed their HIV status from others. HIV-positive MSM reported experiencing greater social isolation and discrimination resulting from being HIV-positive, including loss of housing or employment due to their HIV status, however these differences were not significant. Mental health interventions, as well as structural changes for protection against discrimination, are needed for HIV-positive South African MSM.

Access to substance use disorder (SUD) treatment is a critical issue for women with HIV. This study examined differences in SUD diagnoses, comorbid psychiatric diagnoses, and predictors of SUD treatment initiation among a diverse sample of HIV-positive women (n = 228) and a demographically similar cohort of HIV-negative women (n = 693). Diagnoses and service utilization data were obtained from electronic health records of members of a large integrated healthcare system in Northern California. HIV-positive women were less likely to initiate SUD treatment. Significant racial/ethnic differences were found among both HIV-positive and HIV-negative women with respect to SUD diagnosis type and diagnosis of comorbid psychiatric disorders. Among the HIV-negative women, rates of SUD treatment initiation were lower for black women than for white or Latina women. Multivariable logistic regression models showed that alcohol, cannabis, and opiate diagnoses were predictive of SUD treatment initiation for both cohorts, while amphetamine diagnoses, comorbid depressive disorder, and being white or Latina were predictive of SUD treatment initiation for HIV-negative, but not HIV-positive, women. Findings suggest that clinicians need to be aware of differences in substances of abuse, comorbid psychiatric disorders, and to consider the demographic and social factors that may contribute to differences in SUD treatment initiation among HIV-positive and HIV-negative women.

HIV/AIDS is associated with significant mental health morbidity in high-income countries, and depression associated with HIV/AIDS has been linked with faster disease progression and reduced drug adherence. However, research on mental health is scarce in sub-Saharan Africa where infection levels are highest. This cross-sectional study of 220 HIV-positive outpatients at a dedicated Tanzanian HIV/AIDS care centre assessed sociodemographics, clinical variables and prevalence of ICD-10 common mental health diagnoses via a standardised psychiatric questionnaire (the Clinical Interview Schedule-Revised). Depression or mixed anxiety and depression was identified in 15.5% of subjects, with 4.5% suffering from other anxiety disorders. This suggests routine HIV care in sub-Saharan Africa should include assessment and treatment of mental health issues.
Full Text Available BACKGROUND: Although several studies have investigated whether CCL3L1 copy number variation (CNV influences the risk of HIV-1 infection, there are still no clear conclusions. Therefore, we performed a meta-analysis using two models to generate a more robust estimate of the association between CCL3L1 CNV and susceptibility to HIV-1 infection. METHODS: We divided the cases and controls into two parts as individuals with CCL3L1 gene copy number (GCN above the population specific median copy number (PMN and individuals with CCL3L1 GCN below PMN, respectively. Odds ratios (ORs with 95% confidence intervals (95% CIs were given for the main analysis. We also conducted stratified analyses by ethnicity, age group and sample size. Relevant literatures were searched through PubMed and ISI Web of Knowledge up to March 2010. RESULTS: In total, 9 studies with 2434 cases and 4029 controls were included. ORs for the main analysis were 1.35 (95% CI, 1.02-1.78, model: GCN ≤ PMN Vs. GCN > PMN and 1.70 (95% CI, 1.30-2.23, model: GCN < PMN Vs. GCN ≥ PMN, respectively. Either in stratified analysis, statistically significant results can be detected in some subgroups. CONCLUSIONS: Our analyses indicate that CCL3L1 CNV is associated with susceptibility to HIV-1 infection. A lower copy number is associated with an increased risk of HIV-1 infection, while a higher copy number is associated with reduced risk for acquiring HIV-1.

Social support is an important resource that has been associated with better mental and physical health outcomes among HIV-positive people. However, researchers have not adequately explored how social support functions among HIV-positive African Americans. The purpose of the current study was to understand whether HIV-related support resources are associated with relational functioning and HIV-related problems among a sample of HIV-infected African American dyads. Exactly 34 HIV-infected (i.e., seroconcordant) dyads compromised of HIV-positive African American adults and their HIV-positive adult "informal supporters" from 3 Midwestern urban cities completed psychosocial questionnaires and a communication task. Using the actor-partner interdependence model, we analyzed dyadic data to determine whether there were actor and/or partner effects within dyadic relationships on measures of conflict and HIV-related problems, communication about these problems, and health symptoms. We found significant negative relationships between perceived support and HIV-related problems and perceptions of problem inequity within dyads and a positive relationship between perceived support and communication about these problems within dyads. Contrary to our expectations, we found no relationship between social support and HIV symptoms, relational conflict, or perceptions about dyadic partners' HIV-related problems. Although our study precludes drawing causal conclusions, we found evidence of a relationship between the personal experience of HIV-related problems, communication about these problems, and perceptions of social support among a small sample of HIV-infected African American dyads. These findings suggest the need to consider how support-related communication within HIV-infected dyads might influence and be influenced by problem perceptions. (c) 2016 APA, all rights reserved).
Full Text Available Nocardiosis has been recognized in recent times as an unusual opportunistic infection associated with HIV. Bacteraemia due to this pathogen is even rarer and only few cases have been reported in the literature. We report here a case of pulmonary nocardiosis with bacteraemia, which was initially diagnosed as pulmonary tuberculosis. A high index of suspicion is required to diagnose this infection as the clinical presentation and radiographic features mimic pulmonary tuberculosis.
On basis of clinical data of the patients, 62% (n=146) of them were categorized as "category C", 18.4% (n=43) as "category B", and 19.6% (n=46) as "category A" according to CDC (Center for Disease Control) HIV classification. Among all of them, 60.4% (n=142) had less than 200 CD4T cells, 26% (n=61) had between 200 ...
Full Text Available Purpose. Little is known about the risky sexual behaviors of HIV-positive female sex workers (FSWs in the developing world, which is critical for programmatic purposes. This study aims to shed light on their condom use with regular clients as well as husband/cohabiting partner, a first in India. Methods. Multivariate logistic regression analyses for consistent condom use with regular clients and husband/cohabiting partner are conducted for the sample of 606 HIV-positive FSWs. Results. Older FSWs are 90% less likely and nonmobile FSWs are 70% less likely to consistently use condoms. FSWs on ART are 3.84 times more likely to use condoms. Additionally, FSWs who changed their occupation after HIV diagnosis are 70% less likely to use condoms. FSWs who are currently cohabiting are more likely to consistently use condoms with repeat clients and are 3.22 times more likely to do so if they have felt stigma associated with being HIV-positive. FSWs who have multiple repeat clients, and who do not know the sexual behavior of these clients, are more likely to use condoms consistently. Conclusion. This study would help inform programs to target the following particularly vulnerable HIV-positive FSWs: those who are older, those who changed their occupation post-HIV diagnosis, and those who are nonmobile.

While voluntary medical male circumcision (VMMC) has been shown to be protective against HIV-acquisition, the procedure may place men and their partners at risk of HIV infection in the period following circumcision if sex is resumed before the wound is healed. This prospective cohort study evaluates post-circumcision wound healing to determine whether the 42-day post-circumcision abstinence period, recommended by the World Health Organization and adopted by VMMC programs, is optimal. Men were circumcised by forceps-guided method and their post-circumcision wounds examined weekly for seven weeks and at 12 weeks. Time to complete healing was recorded in completed weeks since circumcision, and its associations with baseline covariates were assessed by Kaplan-Meier methods and Cox Proportional Hazard Models. A total of 215 HIV-negative and 108 HIV-positive men aged 18-35 years (median 26, IQR 23-30) were enrolled. 97.1% of scheduled follow-up visits were completed. At week 4, 59.3% of HIV-positive men and 70.4% of age-matched HIV-negative men were healed. At week 6, these percentages rose to 93.4% in HIV-positive men and 92.6% in age-matched HIV-negative men. There was no difference in the hazard of healing between 108 HIV-positive and 108 age-matched HIV-negative men (HR 0.91 95% CI 0.70-1.20). Early post-operative infection was associated with delayed healing in both HIV-positive and HIV-negative men (HR 0.48 95% CI 0.23-1.00). Our results indicate that the WHO recommendation for 42-days post-circumcision sexual abstinence should be maintained for both HIV-positive and HIV-negative men. It is important to stress condom use upon resumption of sex in all men undergoing circumcision.

Depression in Human Immunodeficiency Virus (HIV) positives has implications such as poor drug compliance, lower quality of life, faster progression to full blown Acquired Immunodeficiency Syndrome (AIDS) and higher mortality. To assess depression, social support and self-esteem in HIV positives and to find out the association of depression with social support and self-esteem among HIV positive patients. Kasturba Medical College (KMC) Hospital, a tertiary care hospital, Mangalore, India and cross-sectional design. Study constituted of 105 HIV positive subjects; depression was assessed using BDI (Beck depression inventory), social support was assessed using Lubben social network scale and self-esteem was assessed using Rosenberg self-esteem scale. Kappa statistics was used to measure the agreement of depression assessed by BDI with clinical diagnosis of depression. Logistic regression analyses were done to find out predictors of depression among HIV positives. All analyses were conducted using Statistical Package for Social Sciences (SPSS) version 11.5. Depression was found to be present in 43.8% of HIV positives. Among the study subjects, 10.5% had high risk for isolation and low self-esteem was found only among 5.7%. In univariate analysis both gender and self-esteem were significantly associated with depression whereas in multivariate analysis only self-esteem was found to be significantly associated with depression. The present study shows a high prevalence of depression in HIV positive patients along with the importance of self-esteem. Copyright © 2011 Elsevier B.V. All rights reserved.

Social support is important to the mental health and well-being of HIV-positive women. Limited information exists about the specific structure and composition of HIV-positive women's support networks or associations of these network properties with mental health outcomes. In this pilot study, the authors examine whether support network characteristics were associated with depressive symptoms. Survey and network data were collected from HIV-positive women (N = 46) via a web-based survey and an iPad application in August 2012. Data were analyzed using multivariate linear regression models in SAS. Depressive symptoms were positively associated with a greater number of doctors in a woman's network; having more HIV-positive network members was associated with less symptom reporting. Women who reported more individuals who could care for them had more family support. Those who reported feeling loved were less likely to report disclosure stigma. This work highlighted that detailed social network data can increase our understanding of social support so as to identify interventions to support the mental health of HIV-positive women. Most significant is the ongoing need for support from peers.

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

Ukraine has one of the largest populations of persons living with HIV in Europe. Data on 2019 HIV-positive married or cohabiting women enrolled in a postnatal cohort from 2007 to 2012 were analysed to investigate prevalence and factors associated with self-reported non-disclosure of HIV status. Median age at enrolment was 27.5 years, with two-thirds diagnosed during their most recent pregnancy. Almost all had received antenatal antiretroviral therapy and 24 % were taking it currently. One-tenth (n = 198) had not disclosed their HIV status to their partner and 1 in 20 (n = 93) had disclosed to no-one. Factors associated with non-disclosure were: unmarried status (AOR 2.99 (95 % CI 1.51-5.92), younger age at leaving full-time education (AOR 0.41 (95 % CI 0.19-0.88) for ≥19 years vs ≤16 years) and lack of knowledge of partner's HIV status (AOR 2.01 (95 % CI 1.09-3.66). Further work is needed to support disclosure in some groups and to explore relationships between disclosure and psychological factors in this setting, including depression, lack of support and perception of stigma.

HIV infection rates are increasing among marginalized women in Ontario, Canada. HIV-related stigma, a principal factor contributing to the global HIV epidemic, interacts with structural inequities such as racism, sexism, and homophobia. The study objective was to explore experiences of stigma and coping strategies among HIV-positive women in Ontario, Canada. We conducted a community-based qualitative investigation using focus groups to understand experiences of stigma and discrimination and coping methods among HIV-positive women from marginalized communities. We conducted 15 focus groups with HIV-positive women in five cities across Ontario, Canada. Data were analyzed using thematic analysis to enhance understanding of the lived experiences of diverse HIV-positive women. Focus group participants (n = 104; mean age = 38 years; 69% ethnic minority; 23% lesbian/bisexual; 22% transgender) described stigma/discrimination and coping across micro (intra/interpersonal), meso (social/community), and macro (organizational/political) realms. Participants across focus groups attributed experiences of stigma and discrimination to: HIV-related stigma, sexism and gender discrimination, racism, homophobia and transphobia, and involvement in sex work. Coping strategies included resilience (micro), social networks and support groups (meso), and challenging stigma (macro). HIV-positive women described interdependent and mutually constitutive relationships between marginalized social identities and inequities such as HIV-related stigma, sexism, racism, and homo/transphobia. These overlapping, multilevel forms of stigma and discrimination are representative of an intersectional model of stigma and discrimination. The present findings also suggest that micro, meso, and macro level factors simultaneously present barriers to health and well being--as well as opportunities for coping--in HIV-positive women's lives.

Attitudes of Italian heterosexual men and women toward gay men, both HIV positive and negative, are poorly investigated. Italian culture is still extremely conservative and provides limited support to the gay community (e.g., lack of same-sex marriage recognition). Consequently, gay men experience social exclusion and disparities. The present study explores the association between homophobia and closeness with sexual orientation and HIV status. 261 heterosexual Italian men and women were asse...

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

Early diagnosis of HIV infection reduces morbidity and mortality. Fourth-generation HIV detection assays are more sensitive because they can detect p24 antigen as well as anti-HIV antibodies. In this study, we evaluated the performance of a new fourth-generation ADVIA Centaur HIV antigen/antibody combo (CHIV) assay (Siemens Healthcare Diagnostics Inc., USA) for early detection of HIV infection and reduction of false positive rate. Four seroconversion panels were included. The third-generation ADVIA Centaur HIV 1/O/2 enhanced (EHIV) assay (Siemens Healthcare Diagnostics Inc., USA) and fourth-generation CHIV assay were used to test each panel for HIV infection. The presence of antigen was confirmed using HIV p24 antigen assay. To evaluate false-positivity and specificity, 54 HIV false-positive and HIV-negative serum samples from 100 hospitalized patients and 600 healthy subjects were included. COMPARED TO THE EHIV ASSAY, THE CHIV ASSAY HAD A SHORTER WINDOW FOR THREE OF THE SEROCONVERSION PANELS: a difference of 10 days and two bleeds in one panel, and 4 days and one bleed in the other two panels. Only 34 of the 54 (63%) samples known to yield false-positive results by EHIV assay had repeatedly yielded reactive results in the CHIV assay. One of the 600 healthy subjects had a false-positive result with the CHIV assay; thus, the specificity was 99.85% (699/700). CHIV accurately determined the reactive results for the HIV-confirmed serum samples from known HIV patients and Korea Food & Drug Administration (KFDA) panels. The new fourth-generation ADVIA Centaur HIV assay is a sensitive and specific assay that shortens the serological window period and allows early diagnosis of HIV infection.

Full Text Available Objective: To determine the prevalence and determinants of chronic periodontitis in HIV positive patients. Methods: A total of 120 HIV positive patients attending the dedicated HIV outpatient clinic of the Lagos University Teaching Hospital, Nigeria were recruited for the study. Their periodontal status was assessed using the community periodontal index of treatment needs. Their CD4+ cell count was determined using the flow-cytometer method. The risk factors for periodontitis including age, gender, education, smoking, CD4+ cell counts, bleeding on probing (BOP were determined. Results: Prevalence of periodontitis was high (63.3% in the HIV positive patients. In a bivariate analysis, significant associations were observed between severity of periodontitis and age ≥35 years (P=0.021, male gender (P=0.005, smoking (P=0.040 and ≥3 community periodontal index of treatment needs sextants exhibiting BOP (P=0.004. In a binary logistic regression, independent predictors of periodontitis were ≥3 sextants exhibiting BOP (odds ratio 1.738, 95% CI 1.339 to 2.256, P=0.000 and age ≥35 years (odds ratio 1.057, 95% CI 1.005 to 1.111, P=0.030. The CD4+ cell counts were not associated with periodontitis in the HIV positive patients (P=0.988. Conclusions: A high prevalence of periodontitis was found among the HIV positive Nigerian patients in this study. Older age ≥35 years and BOP were the determinants of periodontitis. There is therefore a need for close periodontal monitoring of HIV positive Nigerian patients with emphasis on preventive, professional oral prophylaxis.

This study investigated the relationship between HIV health optimism (HHO) (the belief that health will remain good after HIV infection due to treatment efficacy), HIV-positive community attachment (HCA), gay community attachment (GCA) and serostatus disclosure to casual sex partners by HIV-positive men who have sex with men (MSM). Cross-sectional questionnaire data were gathered from 97 HIV-positive MSM attending an HIV treatment clinic in Dublin, Ireland. Based on self-reported disclosure to casual partners, participants were classified according to their pattern of disclosure (consistent, inconsistent or non-disclosers). Multinomial logistic regression was used to assess HHO, HCA and GCA as predictors of participants' pattern of disclosure. Classification as a non-discloser (compared to a consistent discloser) was associated with higher HHO, less HCA and greater GCA. Classification as an inconsistent discloser (compared to a consistent discloser) was associated with higher GCA. The study provided novel quantitative evidence for associations between the constructs of interest. The results suggest that (1) HHO is associated with reduced disclosure, suggesting optimism may preclude individuals reaping the benefits of serostatus disclosure and (2) HCA and GCA represent competing attachments with conflicting effects on disclosure behaviour. Limitations and areas for future research are discussed.
Full Text Available BACKGROUND: Anal HPV infection, which contributes to the development of anal warts and anal cancer, is well known to be common among men who have sex with men (MSM, especially among those HIV positives. However, HIV and anal HPV co-infection among MSM has not been addressed in China. METHODS: A cross-sectional study was conducted in Beijing and Tianjin, China. Study participants were recruited using multiple methods with the collaboration of local volunteer organizations. Blood and anal swabs were collected for HIV-1 serological test and HPV genotyping. RESULTS: A total of 602 MSM were recruited and laboratory data were available for 578 of them (96.0%. HIV and anal HPV prevalence were 8.5% and 62.1%, respectively. And 48 MSM (8.3% were found to be co-infected. The HPV genotypes identified most frequently were HPV06 (19.6%, HPV16 (13.0%, HPV52 (8.5% and HPV11 (7.6%. Different modes of HPV genotypes distribution were observed with respect to HIV status. A strong dose-response relationship was found between HIV seropositivity and multiplicity of HPV genotypes (p<0.001, which is consistent with the observation that anal HPV infection was an independent predictor for HIV infection. CONCLUSIONS: A high prevalence of HIV and anal HPV co-infection was observed in the MSM community in Beijing and Tianjin, China. Anal HPV infection was found to be independently associated with increased HIV seropositivity, which suggests the application of HPV vaccine might be a potential strategy to reduce the acquisition of HIV infection though controlling the prevalence of HPV.

Full Text Available BACKGROUND The global impact of the converging dual epidemics of TB and HIV is one of the major public health challenges. The increasing rate of HIV infection in many countries has had an impact on TB epidemiology. As the prevalence of pulmonary tuberculosis is increasing among HIV seropositive patients with a wide range of immune status and clinical presentations, the present study was undertaken to assess the clinical and laboratory profile of sputum positive pulmonary tuberculosis among HIV seropositive and HIV seronegative patients. MATERIALS AND METHODS The present one year cross-sectional study was conducted in the Department of Medicine, KLES Dr. Prabhakar Kore Hospital and Medical Research Centre, Belgaum on 104 patients with sputum positive pulmonary tuberculosis patients during the period of January 2009 to December 2009. Routine investigations such as blood group, haemogram that is haemoglobin, total count, differential count, erythrocyte sedimentation rate, sputum smears for AFB and chest x-ray were done. RESULTS Seroprevalence of HIV among pulmonary tuberculosis patients was 23.08%. On examination anaemia, undernourishment, lymphadenopathy and the presence of opportunistic infections like oral candidiasis, herpes zoster stain and genital lesions were more predominant among HIV seropositives compared to HIV seronegatives. Mean Hb and TLC were significantly low among HIV seropositives compared to HIV seronegatives. Chest x-ray showed varied presentation. Upper zone infiltration, cavitation and fibrosis were more commonly involved among HIV seronegatives compared to HIV seropositives. CONCLUSION HIV seropositive PTB patients commonly present with fever, weight loss and loss of appetite, while cough with expectoration, haemoptysis, breathlessness were more common with HIV seronegative patients. Cavitation, fibrosis and fibrocavitary lesions were predominantly seen among HIV seronegatives, while infiltration and miliary mottling was

To assess health care utilisation for patients co-infected with TB and HIV (TB-HIV), and to develop a weighted health care index (HCI) score based on commonly used interventions and compare it with patient outcome. A total of 1061 HIV patients diagnosed with TB in four regions, Central/Northern, Southern and Eastern Europe and Argentina, between January 2004 and December 2006 were enrolled in the TB-HIV study. A weighted HCI score (range 0-5), based on independent prognostic factors identified in multivariable Cox models and the final score, included performance of TB drug susceptibility testing (DST), an initial TB regimen containing a rifamycin, isoniazid and pyrazinamide, and start of combination antiretroviral treatment (cART). The mean HCI score was highest in Central/Northern Europe (3.2, 95%CI 3.1-3.3) and lowest in Eastern Europe (1.6, 95%CI 1.5-1.7). The cumulative probability of death 1 year after TB diagnosis decreased from 39% (95%CI 31-48) among patients with an HCI score of 0, to 9% (95%CI 6-13) among those with a score of ≥4. In an adjusted Cox model, a 1-unit increase in the HCI score was associated with 27% reduced mortality (relative hazard 0.73, 95%CI 0.64-0.84). Our results suggest that DST, standard anti-tuberculosis treatment and early cART may improve outcome for TB-HIV patients. The proposed HCI score provides a tool for future research and monitoring of the management of TB-HIV patients. The highest HCI score may serve as a benchmark to assess TB-HIV management, encouraging continuous health care improvement.

Full Text Available In Australia, almost half of HIV-positive people are now aged over 50 and are predominately gay and bisexual men (GBM. Compared to the general HIV-negative population, GBM engage more in behaviours that may increase the risk of age-related comorbidities, including smoking, high alcohol consumption and recreational drug use. The objective of APPLES was to compare comorbidities and risk factors in HIV-positive older GBM with an appropriate control group of HIV-negative GBM. We undertook a prospectively recruited cross-sectional sample of HIV-positive and HIV-negative GBM ≥ 55 years. Detailed data collection included clinic data, a health and lifestyle survey, and blood sample collection. We report key demographic, laboratory markers and self-reported comorbidities by HIV status. For selected comorbidities we also adjust HIV status a priori for age, smoking and body mass index. Over 16 months 228 HIV-positive and 218 HIV-negative men were recruited. Median age was 63 years (IQR: 59-67. Although more HIV-positive men reported having ever smoked, smoking status was not statistically different between HIV positive and HIV negative men (p = 0.081. Greater alcohol use was reported by HIV-negative men (p = 0.002, and recreational drug use reported more often by HIV-positive men (p<0.001. After adjustment, HIV-positive men had significantly increased odds of diabetes (adjusted Odds ratio (aOR: 1.97, p = 0.038, thrombosis (aOR: 3.08, p = 0.007, neuropathy (aOR: 34.6, P<0.001, and non-significantly increased odds for heart-disease (aOR: 1.71, p = 0.077. In conclusion, HIV-positive GBM have significantly increased odds for key self-reported comorbidities. This study underscores the importance of an appropriate HIV-negative control group for more accurate evaluation of the risk and attribution of age-related comorbidities in HIV-positive people.

While tuberculosis (TB) can be diagnosed by microscopy and culture, the sensitivity of Ziehl-Neelsen staining is variable and culture results require 4 - 8 weeks to be determined. Polymerase chain reaction (PCR) and its modifications, including nested PCR, might be promising methods for the rapid diagnosis of TB. This study aimed to evaluate the performance of nested PCR on urine samples of human immunodeficiency virus (HIV)-positive and -negative patients with different manifestations of clinical TB. In a prospective study, three early-morning urine samples from 100 patients with pulmonary TB (PTB) or extrapulmonary TB (EPTB) were evaluated using a molecular target with insertion element IS6110, specific to the Mycobacterium tuberculosis genome, and nested PCR was performed. The results were analyzed with SPSS version 22. A total of 100 patients, including 74 (74%) with PTB and 26 (26%) with EPTB, were enrolled. Positive smears were seen in 38 patients (38%). Lymph nodes were the most commonly involved organ in 14 of the 26 (53.8%) EPTB patients (13.5%). Seven (23.1%) of the EPTB patients were HIV-positive. Urine PCR was positive in only 28 patients (28%). Seven HIV-positive patients with PTB showed positive urine PCR results. Moreover, PCR results were positive in only one of the seven HIV-positive subjects with EPTB. Positive PCR results were found in 20 of the 73 HIV-negative patients (27.4%) and in 8 of the 27 HIV-positive patients (29.6%). Therefore, there was no significant difference between the HIV-negative and HIV-positive patients for urine PCR (sensitivity 29.6%, specificity 72.6%; positive and negative predictive values 28% and 72%, respectively; P = 0.138).

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

The study sought to establish the feasibility and acceptability of anal screening among men MSM. Prospective cohort study. Sexual health clinics in tertiary care. Known HIV-positive and negative MSM who have anoreceptive intercourse. Anal screening with human papilloma virus (HPV) testing, liquid-based cytology and high-resolution anoscopy with biopsy of anoscopic abnormalities. Participants completed questionnaires at baseline and at 6 months. Anal HPV was highly prevalent in MSM (HIV-positive, 88% and HIV-negative, 78%). Despite the high prevalence of cytological abnormality in both HIV-positive (46.2%) and negative (35.0%) MSM, almost half of anal intraepithelial neoplasia (AIN) of all grades were associated with negative cytology. Anoscopically directed biopsies detected AIN3 or worse (AIN3+) in 14 of 203 (6.9%) of HIV-positive MSM and three of 81 (3.7%) HIV-negative MSM. The corresponding prevalence of AIN2+ was 26.6 and 20.9%, respectively. One case of AIN3 was detected at the second visit. Screening was considered to be highly acceptable by participants. The high prevalence of high-risk-HPV and frequency of false negative cytology in this study suggest that high-resolution anoscopy would have most clinical utility, as a primary screening tool for anal cancer in a high-risk group. The prevalence of AIN3+ in HIV-positive MSM lends support for a policy of screening this group, but the high prevalence of lower grade lesions which do not warrant immediate treatment and the limitations of treating high-grade lesions requires careful consideration in terms of a screening policy.

Full Text Available Background. The indications for and outcomes of intensive care unit (ICU admission of HIV-positive patients in resource-poor settings such as sub-Saharan Africa are unknown. Objective. To identify indications for ICU admission and determine factors associated with high ICU and hospital mortality in HIV-positive patients. Methods. We reviewed case records of HIV-positive patients admitted to the medical and surgical ICUs at Groote Schuur Hospital, Cape Town, South Africa, from 1 January 2012 to 31 December 2012. Results. Seventy-seven HIV-positive patients were admitted to an ICU, of whom two were aged 13 (odds ratio (OR 1.4, 95% confidence interval (CI 1.1 - 1.7; p=0.015, receipt of renal replacement therapy (RRT (OR 2.2, 95% CI 1.2 - 4.1; p=0.018 and receipt of inotropes (OR 2.3, 95% CI 1.6 - 3.4; p<0.001. Predictors of hospital mortality were severe sepsis on admission (OR 2.8, 95% CI 0.9 - 9.1; p=0.07, receipt of RRT (OR 1.9, 95% CI 1.0 - 3.6; p=0.056 and receipt of inotropic support (OR 2.0, 95% CI 1.4 - 3.2; p<0.001. Use of highly active antiretroviral therapy (HAART, CD4 count, detectable HIV viral load and diagnosis at ICU admission did not predict ICU or hospital mortality. Conclusions. Respiratory illnesses remain the main indication for ICU in HIV-positive patients. HIV infection is often diagnosed late, with patients presenting with life-threatening illnesses. Severity of illness as indicated by a high APACHE ΙΙ score, multiple organ dysfunction requiring inotropic support and RRT, rather than receipt of HAART, CD4 count and diagnosis at ICU admission, are predictors of ICU and hospital mortality.

Rising incidence rates of HIV and STIs (sexually transmitted infections) among MSM (men who have sex with men) in Germany since 2001 call for new approaches in medical prevention. The present study addresses appropriate parameters to identify those HIV-positive MSM who are at high risk for transmitting HIV and STIs. Over a two-year period, 223 HIV-positive MSM attending the HIV outpatient clinic at the University Medical Center Essen (Germany) were systematically surveyed with respect to their sexual behavior, substance abuse, and psychological well-being in the preceding year. Data analyzed included laboratory and clinical data from the time of the initial HIV diagnosis until January 2014. In HIV-positive MSM, a history of substance abuse, promiscuity, younger age, and known STIs was associated with a greater incidence of unprotected sexual intercourse and STIs. Apart from a detectable viral load, additional HIV-specific parameters associated with an increased HIV transmission risk included untreated HIV infection, adherence problems, changes in antiretroviral treatment over the preceding twelve months, known multiresistant HIV infection, and a higher CD 4 nadir. Despite routine quarterly monitoring of viral loads - the result thereof was communicated to patients - only 60 % of individuals assessed their HIV transmission risk correctly. In HIV-positive MSM, patient history and routine laboratory tests allow for the establishment of patient profiles that suggest sexual behavior associated with a high risk of HIV and STI transmission, thus offering new approaches for medical prevention. © 2017 Deutsche Dermatologische Gesellschaft (DDG).

Full Text Available Abstract Background The proven benefit of integrating cervical cancer screening programme into HIV care has led to its adoption as a standard of care. However this is not operational in most HIV clinics in Nigeria. Of the various reasons given for non-implementation, none is backed by scientific evidence. This study was conducted to assess the willingness and acceptability of cervical cancer screening among HIV positive Nigerian women. Methods A cross sectional study of HIV positive women attending a large HIV treatment centre in Lagos, Nigeria. Respondents were identified using stratified sampling method. A pretested questionnaire was used to obtain information by trained research assistants. Obtained information were coded and managed using SPSS for windows version 19. Multivariate logistic regression model was used to determine independent predictor for acceptance of cervical cancer screening. Results Of the 1517 respondents that returned completed questionnaires, 853 (56.2% were aware of cervical cancer. Though previous cervical cancer screening was low at 9.4%, 79.8% (1210 accepted to take the test. Cost of the test (35.2% and religious denial (14.0% were the most common reasons given for refusal to take the test. After controlling for confounding variables in a multivariate logistic regression model, having a tertiary education (OR = 1.4; 95% CI: 1.03-1.84, no living child (OR: 1.5; 95% CI: 1.1-2.0, recent HIV diagnosis (OR: 1.5; 95% CI: 1.1-2.0 and being aware of cervical cancer (OR: 1.5; 95% CI: 1.2-2.0 retained independent association with acceptance to screen for cervical cancer. Conclusions The study shows that HIV positive women in our environment are willing to screen for cervical cancer and that the integration of reproductive health service into existing HIV programmes will strengthen rather than disrupt the services.

HIV infection induces a state of pellagra in cell culture models. This study compared the nutritional status and the 24-hour urine excretion of N-methylnicotinamide between HIV-positive children and HIV-negative children who were or were not born of mothers with HIV-1 infection. Forty patients were included in the study: HIV-positive children (group 1; n = 20), HIV-negative children born to infected mothers (group 2; n = 10), and HIV-negative control children (group 3; n = 10). Usual dietary intake was assessed by a semiquantitative food-frequency questionnaire. Weight and height were assessed and compared with the reference data of the U.S. National Center for Health Statistics/Centers for Disease Control and Prevention. For the estimation of fat-free mass and total body water, bioelectrical impedance technique was used. N-methylnicotinamide was measured by a modified method of high-performance liquid chromatography. Groups were matched in relation to age, sex, percentage of malnutrition, anthropometric measures, and body composition. Daily niacin intake did not differ statistically across groups (group 1 = 18.0 +/- 11.4 mg/day; group 2 = 18.9 +/- 8.0 mg/day; group 3 = 14.2 +/- 5.2 mg/day), nor did intake of tryptophan, vitamin B6, and zinc. The values of urinary niacin per gram of creatinine were similar and adequate across the groups (group 1 = 4.68 [0.75-14.9]; group 2 = 3.74 [1.13-5.69]; group 3 = 3.85 [1.80-8.19]). HIV-positive children excreted the same amount of N-methylnicotinamide in urine as did the control children. These findings may be attributed to similarities in nutritional status, adequate intestinal absorption (no children experienced diarrhea) and stable clinical condition.

The purpose of this study was to compare the activity of HMR 1043 with those of daptomycin and teicoplanin against gram-positive isolates. Susceptibility tests were performed for 52 strains, 26 parental strains, including staphylococcal, streptococcal, enterococcal, and listerial strains, and 26 HMR 1043-resistant mutants obtained from parental strains by using the Szybalski method. Agar dilution and disk diffusion susceptibility tests were performed by the procedures outlined by the NCCLS. HMR 1043 demonstrated good activity against susceptible and resistant gram-positive bacteria. The activity of HMR 1043 in vitro was less influenced by the presence of calcium ions than that of daptomycin. Susceptibility test breakpoints were not defined because of the poor correlation coefficients obtained with the different disks tested.

HIV status disclosure is often characterized as a dilemma. On the one hand, disclosure can promote health, social support, and psychological well-being. On the other, disclosure can lead to stigmatization, rejection, and other negative social interactions. Previous research has shown that HIV status disclosure is a reasoned process whereby the costs and benefits to oneself and to others are weighed. As such, understanding disclosure requires understanding the reasons for and against disclosure employed by people living with HIV (PLWH). In this study, disclosure among a population disproportionately affected by HIV in the Netherlands, namely African and Afro-Caribbean diaspora, was investigated. Reasons for nondisclosure were fear of stigmatization, previous negative experiences with disclosure, having observed the stigmatization of other PLWH, shame, the desire to protect others - particularly one's children and family - from stigmatization by association and/or worrying, and the belief that one's HIV status is a private matter. Participants reported disclosing because they were in a close and supportive relationship, disclosure led to emotional release, disclosure could lead to emotional or financial support, they felt a perceived duty to inform, and they had a desire to educate others about sexual risk-taking. The findings suggest that stigma plays an important role in disclosure decisions among these populations. They further point to a need for HIV-related stigma reduction interventions in African and Afro-Caribbean communities and culturally sensitive counseling for PLWH whereby caregivers do not automatically assume that disclosure is best but rather provide a safe environment in which the costs and benefits of disclosure can be weighed and strategies for disclosure can be developed, if perceived as beneficial by PLWH.

Health-related vulnerabilities associated with deportation are understudied. We conducted a cross-sectional study to identify factors associated with history of deportation from the US to Mexico among HIV-positive Latinos. From 2009 to 2010, we recruited a convenience sample from HIV clinics in San Diego, US and Tijuana, Mexico. Of 283 participants, 25% reported a prior deportation. Factors independently associated with increased odds of deportation history were being male [adjusted odds ratio (AOR) 2.77; 95% CI 1.18-6.48], having ≤high-school education (AOR 3.87; 95% CI 1.84-8.14), ever using cocaine (AOR 2.46; 95% CI 1.33-4.57), and reporting personalized HIV-stigma: "some have told me HIV is what I deserve for how I lived" (AOR 2.23; 95% CI 1.14-4.37). Lower self-reported antiretroviral medication adherence (AOR 0.35; 95% CI 0.12-0.96) and perceiving HIV-stigma: "most people believe a person who has HIV is dirty" (AOR 0.49; 95% CI 0.25-0.94) were associated with decreased odds of deportation history. Deportation is associated with specific socioeconomic indicators that are known to impact the health of individuals living with HIV.

This study was designed to investigate the factors associated with the high rate of false-positive test results observed with the 4th-generation Murex HIV Ag/Ab Combination EIA (enzyme immunoassay) within an adolescent and young-adult cohort in northwest Tanzania. (4th-generation assays by definition detect both HIV antigen and antibody.) The clinical and sociodemographic factors associated with false-positive HIV results were analyzed for 6,940 Tanzanian adolescents and young adults. A subsample of 284 Murex assay-negative and 240 false-positive serum samples were analyzed for immunological factors, including IgG antibodies to malaria and schistosoma parasites, heterophile antibodies, and rheumatoid factor (RF) titers. Conditional logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs). False-positive HIV test results were associated with evidence of other infections. False positivity was strongly associated with increasing levels of Schistosoma haematobium worm IgG1, with adolescents with optical densities in the top quartile being at the highest risk (adjusted OR=40.7, 95% CI=8.5 to 194.2 compared with the risk for those in the bottom quartile). False positivity was also significantly associated with increasing S. mansoni egg IgG1 titers and RF titers of >or=80 (adjusted OR=8.2, 95% CI=2.8 to 24.3). There was a significant negative association between Murex assay false positivity and the levels of S. mansoni worm IgG1 and IgG2 and Plasmodium falciparum IgG1 and IgG4. In Africa, endemic infections may affect the specificities of immunoassays for HIV infection. Caution should be used when the results of 4th-generation HIV test results are interpreted for African adolescent populations.

Co-infection of HIV and other sexualLy transmitted diseases (STDs) is common. The Centers for Disease Control and Prevention (CDC) recommends routine yearly screening for STDs in HIV carriers. There is only scarce data on the prevalence of STD in HIV positive individuals in Israel and no current recommendations on this issue are available. To evaluate the prevalence of STDs, in HIV positive females attending the HIV Clinic at the Soroka University Medical Center in Beer Sheva and to compare prevalence and risk factors for STDs between HIV female carriers of Ethiopian and non-Ethiopian origin. Eighty five HIV-positive women were enrolled in the study. Demographic data and sexual behavior were obtained and medical records were reviewed. Cervical swabs for Neisseria gonorrhoeae, Herpes simplex 1 and 2, Ureaplasma urealyticum and Mycoplasma hominis and serum samples for hepatitis B, C and syphilis were obtained. Thirty two of the study participants (37.6%) had at least one STD and in eleven cases (12.9%) two or more STDs were found. Ureaplasma urealyticum was the most frequent pathogen (29.4%). Prevalence for Mycoplasma hominis, HSV1 and 2, Neisseria gonorrhoeae, syphilis and HBV was low. Despite significant differences in sexual behavior between women of Ethiopian and non-Ethiopian origin there were no differences in the prevalence of STDs in the two groups. HCV was significantly more prevalent in women of non-Ethiopian origin, due to high use of intravenous drugs in this group. There was no correlation between CD4 levels and the prevalence of STDs in both groups. A relatively low prevalence of STDs among female HIV carriers was found, despite low condom use. The exclusion of males in this study may have contributed to this. The most frequent pathogen found in this study was asymptomatic Ureaplasma urealyticum (29.4%). As this pathogen may cause premature delivery and fetal death it seems important to routinely screen HIV-positive fertile women for its presence. A

Haitian immigrant women, the largest growing Black ethnic group in Miami, experience the highest rates of cervical cancer and account for one of the largest populations diagnosed with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) in South Florida. Using community-based participatory research methods, we conducted a pilot study to examine human papilloma virus (HPV)/cervical cancer knowledge and identify intervention preferences among HIV positive Haitian women. Community health workers conducted three focus groups with 21 HIV-positive Haitian women. All sessions were conducted in Haitian Kreyol, digitally recorded, and subsequently interpreted and transcribed into English. The first focus group assessed HPV/cervical cancer knowledge, the second session explored HPV/cervical cancer considerations specific to HIV-positive women, and the third focus group discussed HPV/cervical cancer screening and intervention preferences. Data analysis was guided by a grounded theory approach. Our sample had limited HPV/cervical cancer knowledge. Misconceptions about screening, transmission, and treatment were common. Participants felt that stigma by providers impacted negatively the care they received and that stigma by the community diminished social support. Strong support for culturally tailored interventions to improve HPV/cervical cancer knowledge was expressed. Although no participants had participated in research previously, all were willing to participate in future trials. There is critical need for culturally relevant interventions to improve HPV/cervical cancer knowledge among HIV-positive Haitian women. Copyright © 2015 Jacobs Institute of Women's Health.

Experiences of past and current gender-based violence are common among HIV-positive women in the United States, who are predominantly from ethnic minority groups. However, culturally congruent, feasible interventions for HIV-positive women who have experienced past and/or current violence are not widely available. The Office on Women's Health Gender Forum has made several recommendations for responding to the National HIV/AIDS Strategy Implementation Plan, including recommendations to incorporate gender-based violence prevention into a comprehensive, gender-responsive national strategy. This paper draws on an example of a community-based project for HIV-positive women, the Healing Our Women Project, to illustrate how violence prevention can be achieved within peer-led and community-based programming. Strong community partnerships, responsiveness to community needs and local cultural norms, a trained workforce, and culturally competent care are programmatic cornerstones of gender-responsive services. HIV-positive women with histories of gender-based violence and risk factors for current and future violence deserve the highest quality gender-responsive services to ensure that they can address their health needs within contexts of safety and respect.

Full Text Available Abstract Background Human embryonic stem (hES cells hold considerable promise for cell replacement and gene therapies. Their remarkable properties of pluripotency, self-renewal, and tractability for genetic modification potentially allows for the production of sizeable quantities of therapeutic cells of the hematopoietic lineage. Dendritic cells (DC arise from CD34+ hematopoietic progenitor cells (HPCs and are important in many innate and adaptive immune functions. With respect to HIV-1 infection, DCs play an important role in the efficient capture and transfer of the virus to susceptible cells. With an aim of generating DCs from a renewable source for HIV-1 studies, here we evaluated the capacity of hES cell derived CD34+ cells to give rise to DCs which can support HIV-1 infection. Results Undifferentiated hES cells were cultured on S17 mouse bone marrow stromal cell layers to derive CD34+ HPCs which were subsequently grown in specific cytokine differentiation media to promote the development of DCs. The hES derived DCs (hES-DC were subjected to phenotypic and functional analyses and compared with DCs derived from fetal liver CD34+ HPC (FL-DC. The mature hES-DCs displayed typical DC morphology consisting of veiled stellate cells. The hES-DCs also displayed characteristic phenotypic surface markers CD1a, HLA-DR, B7.1, B7.2, and DC-SIGN. The hES-DCs were found to be capable of antigen uptake and stimulating naïve allogeneic CD4+ T cells in a mixed leukocyte reaction assay. Furthermore, the hES-DCs supported productive HIV-1 viral infection akin to standard DCs. Conclusion Phenotypically normal and functionally competent DCs that support HIV-1 infection can be derived from hES cells. hES-DCs can now be exploited in applied immunology and HIV-1 infection studies. Using gene therapy approaches, it is now possible to generate HIV-1 resistant DCs from anti-HIV gene transduced hES-CD34+ hematopoietic progenitor cells.

Aichi viruses (AiV) have been detected in patients with diarrheal diseases (DD). The aim of this study was to assess AiV infection rates in hospitalized children with DD, including 123 HIV-1 seropositive and 125 HIV-1 seronegative patients, in two public pediatric hospitals in Rio de Janeiro, Brazil. AiV was investigated by nested RT-PCR. The AiV-positive samples were also tested for specie A rotavirus, norovirus, astrovirus, enteric adenovirus and bocavirus in order to assess co-infections. AiV parcial genome sequencing and phylogenetic analyses were performed. AiV were detected in 9/123 (7.32%) of the HIV-1 seropositive subjects and 1/125 (0.8%) of the HIV seronegative patients with DD (p = 0.019). The phylogenetic analysis of positive samples disclosed that: i) 13 samples were characterized as genotype A, with one of them being from the HIV-1 seronegative patient; ii) one sample from a HIV-1 seropositive patient was characterized as genotype B. AiV genotype A was grouped into 3 genetic clusters. Data suggest that AiV may be an opportunistic pathogen infecting children with AIDS and DD.

Human immunodeficiency virus (HIV)-1-associated dementia is a frequent consequence of HIV infection and is associated with neuronal deficits. Increased concentrations of the kynurenine pathway metabolites 3-hydroxykynurenine (3-HK) and quinolinic acid (QA) may contribute to this neuronal damage. We measured 3-HK concentrations and the activity of its catabolising enzyme, 3-hydroxykynureninase, in postmortem brain tissue from eight controls and 32 HIV-positive patients, including a group that exhibited dementia. 3-HK concentrations were significantly increased (over threefold) in the HIV-positive group when compared with controls. This increase was greater in those patients with dementia, but it was still apparent in the nondemented cases. 3-Hydroxykynureninase activity was significantly increased in the HIV-infected group compared with the control values. The effect was apparent in both nondementia and dementia cases, although the latter showed a slightly greater increase. The 3-HK content increase is thus unrelated to a reduction in activity of this enzyme and is likely to reflect an overall increase in the kynurenic metabolic pathway. Elevated levels of the neurotoxin 3-HK may contribute to the neuronal deficits underlying HIV-associated dementia.

Enzyme immunoassay (EIA) with the use of test systems based on recombinant HIV antigens has yielded positive results much more often than that with the test systems based on HIV lysate. In comparison with the use of protein A-peroxidase conjugate, the use of antiglobulin conjugates decreased the specificity of EIA, thus ruling out the false positive results. The tested sera containing antibodies to antigens of enteric bacilli could yield false positive EIA results with test systems prepared from recombinant antigens due to the interaction of these antibodies with antigens of enteric bacilli. A conclusion on the usefulness of the control for the presence of the components of enteric bacilli, producers of HIV antigen, and their elimination from recombinant preparations is made.

This study's objectives were: (1) to describe and explore the ethical dilemmas surrounding the HIV-positive person in the workplace in South Africa; and (2) to describe the Rational Interaction for Moral Sensitivity (RIMS) approach as a possible mechanism for solving these ethical dilemmas. A qualitative, exploratory and descriptive research design was used. The target populations were HIV-positive employees and occupational health nurses working for a South African company. Data collected through individual HIV-positive employee interviews and occupational health nurse workgroups were analysed. The ethical dilemmas were conceptualized and described within the theoretical framework of the principles of ethics, namely, autonomy, beneficence, justice and confidentiality. To elicit a solution to the dilemmas, the data were recontextualized using the RIMS approach, a group decision-making strategy designed for the business environment.

The dihydropteroate sulfate (DHPS) gene is associated with resistance to sulfa/sulfone drugs in Pneumocystis jirovecii. We investigated the DHPS mutation rate in three groups of Iranian HIV-positive and HIV-negative patients by polymerase chain reaction-restricted fragment length polymorphism analysis. Furthermore, an association between P. jirovecii DHPS mutations and strain typing was investigated based on direct sequencing of internal transcribed spacer region 1 (ITS1) and ITS2. The overall P. jirovecii DHPS mutation rate was (5/34; 14.7%), the lowest rate identified was in HIV-positive patients (1/16; 6.25%) and the highest rate was in malignancies patients (3/11; 27.3%). A moderate rate of mutation was detected in chronic obstructive pulmonary disease (COPD) patients (1/7; 14.3%). Most of the isolates were wild type (29/34; 85.3%). Double mutations in DHPS were detected in patients with malignancies, whereas single mutations at codons 55 and 57 were identified in the HIV-positive and COPD patients, respectively. In this study, two new and rare haplotypes were identified with DHPS mutations. Additionally, a positive relationship between P. jirovecii strain genotypes and DHPS mutations was identified. In contrast, no DHPS mutations were detected in the predominant (Eg) haplotype. This should be regarded as a warning of an increasing incidence of drug-resistant P. jirovecii strains. © The Author 2015.

For people living with HIV, exposure to sexual violence (SV) is associated with decreased adherence to antiretroviral medication, a primary predictor of their survival. Identification of risk factors for SV is a pressing issue in sub-Saharan Africa, where the global majority of HIV-positive women live and the prevalence of SV against women is high. We used qualitative data to examine SV against HIV-positive women enrolled in HIV care in Kenya. Respondents identified husbands as perpetrators of SV in the context of women's efforts to use condoms as directed by HIV care providers.

Full Text Available Tetherin/BST-2/CD317 is a recently identified antiviral protein that blocks the release of nascent retrovirus, and other virus, particles from infected cells. An HIV-1 accessory protein, Vpu, acts as an antagonist of tetherin. Here, we show that positive selection is evident in primate tetherin sequences and that HIV-1 Vpu appears to have specifically adapted to antagonize variants of tetherin found in humans and chimpanzees. Tetherin variants found in rhesus macaques (rh, African green monkeys (agm and mice were able to inhibit HIV-1 particle release, but were resistant to antagonism by HIV-1 Vpu. Notably, reciprocal exchange of transmembrane domains between human and monkey tetherins conferred sensitivity and resistance to Vpu, identifying this protein domain as a critical determinant of Vpu function. Indeed, differences between hu-tetherin and rh-tetherin at several positions in the transmembrane domain affected sensitivity to antagonism by Vpu. Two alterations in the hu-tetherin transmembrane domain, that correspond to differences found in rh- and agm-tetherin proteins, were sufficient to render hu-tetherin completely resistant to HIV-1 Vpu. Interestingly, transmembrane and cytoplasmic domain sequences in primate tetherins exhibit variation at numerous codons that is likely the result of positive selection, and some of these changes coincide with determinants of HIV-1 Vpu sensitivity. Overall, these data indicate that tetherin could impose a barrier to viral zoonosis as a consequence of positive selection that has been driven by ancient viral antagonists, and that the HIV-1 Vpu protein has specialized to target the transmembrane domains found in human/chimpanzee tetherin proteins.

Research on the role psychiatric factors in HIV disease management has yielded discrepant findings, possibly because prior studies did not include comprehensive psychiatric screeners. This study administered a validated screener to examine psychiatric correlates of highly active antiretroviral therapy (HAART) utilization and viral load. Community-recruited, HIV-positive impoverished persons provided sociodemographic information, completed a Diagnostic Interview Schedule that screened for psychiatric disorders, and provided a blood sample to measure HIV disease markers. In this cross-sectional investigation with 227 participants, a multiple logistic regression model examined correlates of HAART utilization compared to a reference group that was eligible for (i.e. CD4(+) cell count impoverished persons and boost the effectiveness of 'test and treat' approaches to HIV prevention.

Risk perceptions are important in HIV research and interventions; mixed results were found between HIV-related perceptions and behaviors. We interviewed 377 sexually active injecting drug users in China, finding mixed associations between HIV-related risk perception assessed by two general measures and two previous risk behaviors (syringe sharing: p.05) – partially supporting the ‘reflective hypothesis’ that reflection on previous behaviors increases risk perceptions. When we use specific measures for risk perceptions (HIV transmission via unprotected sex with specific types of sex partner and via syringe sharing) and use behavioral intention to adopt protective risk behaviors (condom use and avoid syringe sharing totally) as dependent variables, positive significant associations were observed – supporting the motivational hypothesis that risk perceptions motivate one to adopt protective behaviors. The direction and significance of the associations of concern depends on types of measures used. It has important implications on research design, data interpretation and services. PMID:23284896
Full Text Available Background: The converging epidemics of HIV and tuberculosis (TB pose one of the greatest public health challenges of our time. Rapid diagnosis of TB is essential in view of its infectious nature, high burden of cases, and emergence of drug resistance. Objective: The purpose of this present study was to evaluate the feasibility of implementing the microscopic observation drug susceptibility (MODS assay, a novel assay for the diagnosis of TB and multi-drug-resistant tuberculosis (MDR-TB directly from sputum specimens, in the Indian setting. Materials and Methods: This study involved a cross-sectional, blinded assessment of the MODS assay on 1036 suspected cases of pulmonary TB in HIV-positive and HIV-negative patients against the radiometric method, BD-BACTEC TB 460 system. Results: Overall, the sensitivity, specificity, positive predictive value, and negative predictive value of the MODS assay in detecting MTB among TB suspected patients were 89.1%, 99.1%, 94.2%, 95.8%, respectively. In addition, in the diagnosis of drug-resistant TB, the MODS assay was 84.2% sensitive for those specimens reporting MDR, 87% sensitivity for those specimens reporting INH mono-resistance, and 100% sensitive for specimens reporting RIF mono-resistance. The median time to detection of TB in the MODS assay versus BACTEC was 9 versus 21 days (P < 0.001. Conclusion: Costing 5 to 10 times lesser than the automated culture methods, the MODS assay has the potential clinical utility as a simple and rapid method. It could be effectively used as an alternative method for diagnosing TB and detection of MDR-TB in a timely and affordable way in resource-limited settings.

Full Text Available Toxoplasma gondii, the obligate intracellular parasite is life threatening in AIDS patients. Diagnosis of toxoplasmosis is based on serological methods especially increasing of IgM and IgG titers, but finding of parasite or its components (antigenemia may be beneficial method in order to detection of acute toxoplasmosis in immunocompromised patients.Ninety-four serum samples from HIV positive patients were collected from Sanandaj, Kordistan west of Iran. These patients were lived in Sanandaj of whom 26 were prisoners infected with HIV virus in prison. Toxoplasma gondii antibodies were determined by IgG ELISA. T. gondii antigen was identified by capture-ELISA. PCR was performed on samples with T. gondii antigenemia. CD4+ T cells counts had been determined by flowcytometry and were obtained from records of each patient.Among the examined HIV seropositive individuals, 19.1% (18/94 and 5.3% (5/94 were positive for Toxoplasma-IgG and antigenemia, respectively. Besides, one of the samples was positively detected by PCR method. Mean age of participants was 37.9 ± 9.5 year. Prevalence of IgG antibody and antgenemia was higher in age group of 40-50 years old. The Mean of CD4+ T cells counts of participants (total of HIV+ patients, IgG positive patients and patients with antigenemia was 699.2 ± 345.2, 655.1 ± 237.9 and 620.2 ± 215.1 respectively.Capture-ELISA and PCR could confirm the T. gondii acute infection in HIV positive patients. For precise diagnosis of acute toxoplasmosis in HIV positive patient, performance of more studies based on more sensitive types of PCR is suggested.

The rapid identification and antibiotic susceptibility test of bacteria causing bloodstream infections are given a very high priority by clinical laboratories. In an effort to reduce the time required for performing antibiotic susceptibility test (AST), we have developed a new method to be applied from positive blood culture bottles. The design of method was performed using blood culture bottles prepared artificially with five strains which have a known susceptibility. An aliquot of the blood culture was subcultured in the presence of specific antibiotics and bacterial counts were monitored using the Sysmex UF-1000i flow cytometer at different times up to 180min. Receiver operating curve (ROC) analysis allowed us to find out the cut-off point for differentiating between sensitive and resistant strains to the tested antibiotic. This procedure was then validated against standard commercial methods on a total of 100 positive blood culture bottles from patients. First, bacterial identification was performed by matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF-MS) directly from positive blood culture bottles as we have previously reported. Secondly, antibiotic susceptibility test was performed in the same way that was carried out in artificially prepared blood culture bottles. Our results indicate that antibiotic susceptibility test can be determined as early as 120min since a blood culture bottle is flagged as positive. The essential agreement between our susceptibility test and commercial methods (E-test, MicroScan and Vitek) was 99%. In summary, we conclude that reliable results on bacterial identification and antibiotic susceptibility test performed directly from positive blood culture bottles can be obtained within 3h.

A systematic screening for measles, mumps, rubella (MMR) and varicella zoster virus (VZV) in HIV-positive adult immigrants in Spain was evaluated, and factors associated with MMR and VZV vaccines' indication were studied. Every HIV-positive immigrant was tested for VZV and MMR-IgG. MMR vaccine was indicated to patients with lymphocytes CD4+ >200 cells/mm³ and a negative measles-IgG, a negative mumps-IgG and/or a negative rubella-IgG. VZV vaccine was indicated to every VZV-IgG negative patient with CD4+ >400 cells/mm³. In total, 289 patients were screened; seroprevalence was 95.2%, 92.2%, 70.3% and 89.3% for VZV, measles, mumps and rubella IgG, respectively. Having a negative VZV-IgG was statistically associated with coming from sub-Saharan Africa (prevalence ratio [PR]: 6.52; 95% CI: 1.71-24.84; p=0.006), while having secondary education was a protective factor (PR: 0.25; 95% CI: 0.07-0.97; p=0.045). Fourteen patients (4.8%) had indication of VZV vaccine; vaccination was feasible in 21.4% of them at first visit. Eighty-one patients (29.7%) had indication of MMR vaccine, most of them due to mumps-IgG negative (53.1%) or rubella-IgG negative (24.7%). Age < 30 years at first visit was the only factor statistically associated with MMR vaccine indication (PR: 1.47; 95% CI: 1.02-2.11; p=0.04). According to CD4+ cell counts, vaccination was feasible in 71.6% of patients at first visit. In conclusion, more than a third of HIV-infected immigrant patients are susceptible to at least one easily preventable infectious disease. Especial attention should be given to immigrant women of childbearing age.

The indications for and outcomes of intensive care unit (ICU) admission of HIV-positive patients in resource-poor settings such as sub-Saharan Africa are unknown. To identify indications for ICU admission and determine factors associated with high ICU and hospital mortality in HIV-positive patients. We reviewed case records of HIV-positive patients admitted to the medical and surgical ICUs at Groote Schuur Hospital, Cape Town, South Africa, from 1 January 2012 to 31 December 2012. Seventy-seven HIV-positive patients were admitted to an ICU, of whom two were aged <18 years and were excluded from the final analysis. HIV infection was newly diagnosed in 37.3% of the patients admitted during the study period. HIV-positive patients had a median CD4 count of 232.5 (interquartile range 59 - 459) cells/µL. Respiratory illness, mainly community-acquired pneumonia, accounted for 30.7% of ICU admissions. ICU and hospital mortality rates were 25.3% and 34.7%, respectively. Predictors of ICU mortality included an Acute Physiology and Chronic Health Evaluation ΙΙ (APACHE II) score >13 (odds ratio (OR) 1.4, 95% confidence interval (CI) 1.1 - 1.7; p=0.015), receipt of renal replacement therapy (RRT) (OR 2.2, 95% CI 1.2 - 4.1; p=0.018) and receipt of inotropes (OR 2.3, 95% CI 1.6 - 3.4; p<0.001). Predictors of hospital mortality were severe sepsis on admission (OR 2.8, 95% CI 0.9 - 9.1; p=0.07), receipt of RRT (OR 1.9, 95% CI 1.0 - 3.6; p=0.056) and receipt of inotropic support (OR 2.0, 95% CI 1.4 - 3.2; p<0.001). Use of highly active antiretroviral therapy (HAART), CD4 count, detectable HIV viral load and diagnosis at ICU admission did not predict ICU or hospital mortality. Respiratory illnesses remain the main indication for ICU in HIV-positive patients. HIV infection is often diagnosed late, with patients presenting with life-threatening illnesses. Severity of illness as indicated by a high APACHE ΙΙ score, multiple organ dysfunction requiring inotropic support and RRT
Full Text Available Introduction: Oral manifestations can be the first signs of human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS and a useful marker for the progression of this disease. The present study aimed to determine the prevalence of oral manifestations and examine their relationship with socio-demographic factors in HIV-positive patients in the health centers affiliated to Zahedan University of Medical Sciences (Southeast Iran. Methods: In this cross-sectional study in addition to determining oral manifestations based on the classification of EC-clearing house (European Commission clearing house, information such as age, gender, marital status, residence, education, occupation, habits, oral hygiene, loss of weight in the last six months. Body Mass Index (BMI, mode of HIV transmission, stage of disease, anti-retroviral therapy (ART, and duration of HIV were gathered through direct question from the patients or the information contained in their records. Then the relationship between various factors and oral manifestations was analyzed using Chi-square, Fisher’s Exact Test, Student T Test, Mann- Whitney tests and logistic regression. Results: Oral examination was performed on 119 HIV-positive patients who were 69.7% male and 30.3% female and had a mean age of 35.4±12.7 years. Oral manifestations were found in 57.1% of the patients. Pseudomembranous candidiasis (34.1% and linear gingival erythema (33% were the most common lesions in these patients. The probability of oral manifestations occurrence increased with age and duration of smoking in smokers with HIV (P=0.036 and P=0.012, respectively. Conclusion: Most oral manifestations were those strongly associated with HIV infection (91%. Timely diagnosis and treatment of oral manifestations in HIV patients should be considered in conjunction with other treatments.

Full Text Available Contraception can reduce the dual burden of high fertility and high HIV prevalence in sub-Sahara Africa, but significant barriers remain regarding access and use. We describe factors associated with nonuse of contraception and with use of specific contraceptive methods in HIV positive and HIV negative Rwandan women. Data from 395 HIV-positive and 76 HIV-negative women who desired no pregnancy in the previous 6 months were analyzed using univariate and multivariate logistic regression models to identify clinical and demographic characteristics that predict contraceptive use. Differences in contraceptive methods used were dependent on marital/partner status, partner’s knowledge of a woman’s HIV status, and age. Overall, condoms, abstinence, and hormonal methods were the most used, though differences existed by HIV status. Less than 10% of women both HIV+ and HIV− used no contraception. Important differences exist between HIV-positive and HIV-negative women with regard to contraceptive method use that should be addressed by interventions seeking to improve contraceptive prevalence.

Full Text Available We report on a case of a patient with HIV infection, diagnosed 18 months prior to the development of an anti-glomerular basement membrane (anti-GBM rapidly progressive glomerulonephritis; this is probably the first report of such an association. A 30-year-old white man presented with elevation of serum creatinine (1.3 - 13.5 mg/dL within one month. At admission, the urinalysis showed proteinuria of 7.2 g/L and 8,000,000 erythrocytes/mL. Renal biopsy corresponded to a crescentic diffuse proliferative glomerulonephritis mediated by anti-GBM, and serum testing for anti-GBM antibodies was positive; antinuclear antibodies (ANA and anti-neutrophilic cytoplasmic antibodies (ANCA were also positive. The patient underwent hemodyalisis and was treated with plasmapheresis, cyclophosphamide and prednisone. The association described here is not casual, as crescentic glomerulonephritis is not common in HIV-positive patients, anti-GBM glomerulonephritis is rare and anti-GBM antibodies are frequently observed in HIV-positive subjects when compared to the overall population. Based on the current case and on the elevated frequency of the positivity for such antibodies in this group of patients, it is advisable to be aware of the eventual association between these two conditions and to promote an active search for anti-GBM antibodies and early diagnosis of eventual urinary abnormalities in HIV-positive subjects, considering the severity of anti-GBM glomerulonephritis.

Full Text Available We present the first reported case of papulonodular secondary syphilis in an HIV-positive transgender female. Syphilis is classified into primary, secondary, latent, and tertiary stages, with secondary syphilis having notably diverse cutaneous manifestations. Our patient presented with diverse lesions throughout her body, all pathologically consistent with papulonodular secondary syphilis. Proper identification of the multiple presentations of syphilis is crucial to early diagnosis and treatment. This report seeks to broaden the scope of dermatological manifestations that arise secondary to papulonodular syphilis in HIV-positive patients.

The social context of living in poverty has a direct and indirect impact on a woman's health and well-being. This cross-sectional study investigates the relationship between housing and adherence to treatment, emotional wellness, environmental safety, physical health status, and risk behaviors among HIV-positive women receiving services from an AIDS service organization in the mid-South. Significant differences were found between stably housed and unstably housed women on the dependent outcome variables. Results suggest that housing services for HIV-positive women may be an effective way to increase their health and well-being as well as prevent transmission to others.
Full Text Available Respiratory syncytial virus (RSV is commonly known to cause an influenza-like illness. However, it can also cause more severe disease in young children and older adults comprising of organ transplant patients with immunocompromised status. Till date, only four cases of RSV infections have been reported in HIV-positive adults. We describe here a case of HIV-positive female with relatively preserved immune function who presented with RSV infection requiring ventilation and showed improvement after prompt treatment with intravenous immunoglobulin.

Research suggests that self-esteem in gay and bisexual men may be linked with sexual risk-taking behaviors. As part of a larger investigation into the sexual practices of gay and bisexual men, we assessed serostatus, self-esteem, condom use, and HIV disclosure to sexual partners. Among HIV-negative men, no relationships were found between their self-esteem and tendency to discuss their and their partners’ HIV status. However, among HIV-positive men, there was a positive relationship between s...

Improved virological and immunological outcomes and reduced toxicity of antiretroviral combination therapy (ART) raise the hope that life expectancy of HIV-positive persons on ART will approach that of the general population. We systematically review the literature and summarize published estimates of life expectancy of HIV-positive populations on ART. We compare their life expectancy with the life expectancy of the general or, in sub-Saharan Africa, HIV-negative populations, by time period and gender. Ten relevant studies were published from 2006 to 2015. Three studies were from Canada, two from European countries, three from sub-Saharan Africa and two were multicountry studies. Life expectancy increased over time in all studies and regions. Expressed as the percentage of life expectancy in the HIV-negative or general population, estimated life expectancy at age 20 years in HIV-positive people on ART ranged from 60.3% (95% CI 58.0-62.6%) in Rwanda (2008-2011) to 89.1% (95% CI 84.7-93.6%) in Canada (2008-2012). The percentage of life expectancy in the HIV-negative or general population achieved was higher in HIV-positive women than in HIV-positive men in all countries, except for Canada wherein the opposite was the case. Life expectancy in HIV-positive people on ART has improved worldwide in recent years, but important gaps remain compared with the general and HIV-negative population, and between regions and genders.

Efforts to reach HIV-positive men who have sex with men (MSM) and link them to care must be expanded; however, finding and recruiting them remains a challenge. We compared the efficiency of three recruitment sources in reaching self-identified HIV-positive MSM with various characteristics. Relative to recruitment online and at clubs and bars, AIDS Service Organizations (ASOs) were significantly more efficient in reaching HIV-positive MSM in general. This was also true for those with specific characteristics of interest such as substance/stimulant use, and HIV-positive MSM who were racial/ethnic minorities. Both ASOs and online recruitment were more efficient than clubs and bars in reaching HIV-positive MSM not taking HIV medication. This was also the case for White HIV-positive MSM in general, and White HIV-positive MSM who used substances and stimulants. Online recruitment was also more efficient than clubs and bars in reaching HIV-positive MSM who were young across the board.

Research has shown that spirituality has a positive effect on mental and physical health; however, few studies have explored the influence of spirituality on purpose in life and well-being in persons living with HIV. This descriptive cross-sectional study was designed to examine the relationship between spirituality, purpose in life, and well-being in a sample of 46 HIV-positive men and women. Spirituality was measured using the Spiritual Involvement and Beliefs Scale-Revised (SIBS-R), purpose in life was measured using the Purpose in Life (PIL) test, and well-being was measured using the General Well-Being (GWB) Schedule. Demographic data on gender, age, length of time living with diagnosis of HIV/AIDS, employment status, and religious affiliation were also collected. Spirituality was reported to be significantly correlated with purpose in life (r = .295, p = .049) but not with well-being (r = .261, p = .084). Additionally, the SIBS-R, PIL, and GWB had alpha coefficients greater than .83, suggesting they are reliable and valid measures for this population of HIV-positive persons. The result that spirituality and purpose in life were significantly correlated offers the potential for designing nursing interventions and care delivery approaches that support psychological adaptation to HIV. Further studies with larger and more diverse samples are needed to better understand the role of well-being in healing.
Full Text Available Objective. To evaluate whether HIV infected pregnant women with concomitant sexually transmitted infection (STIs are at increased risk of adverse perinatal and neonatal outcomes. Methods. We conducted a cohort study of HIV positive women who delivered at an inner-city hospital in Atlanta, Georgia, from 2003 to 2013. Demographics, presence of concomitant STIs, prenatal care information, and maternal and neonatal outcomes were collected. The outcomes examined were the association of the presence of concomitant STIs on the risk of preterm birth (PTB, postpartum hemorrhage, chorioamnionitis, preeclampsia, intrauterine growth restriction, small for gestational age, low Apgar scores, and neonatal intensive care admission. Multiple logistic regression was performed to adjust for potential confounders. Results. HIV positive pregnant women with concomitant STIs had an increased risk of spontaneous PTB (odds ratio (OR 2.11, 95% confidence interval [CI] 1.12–3.97. After adjusting for a history of preterm birth, maternal age, and low CD4+ count at prenatal care entry the association between concomitant STIs and spontaneous PTB persisted (adjusted OR 1.96, 95% CI 1.01–3.78. Conclusions. HIV infected pregnant women with concomitant STIs relative to HIV positive pregnant women without a concomitant STI are at increased risk of spontaneous PTB.

In the USA, HIV-positive Black men who have sex with men show large disparities in disease outcomes compared to other racial/ethnic and risk groups. This study examined the strategies that HIV-positive Black men who have sex with men use to cope with different types of discrimination. A total of 27 HIV-positive Black men who have sex with men participated in semi-structured interviews, which were transcribed verbatim and coded using thematic analysis by multiple raters. Major coping themes included reactive avoidance (using behaviours, cognitions and emotions to escape from discrimination), a common reaction to racism; proactive avoidance (avoiding situations in which discrimination is anticipated), manifested as selective disclosure of HIV-serostatus; external attribution for discrimination (versus self-blame), used more for sexual orientation and HIV discrimination; and social support-seeking, which most often emerged in response to racism. Active coping strategies, such as self-advocacy (countering discrimination directly or indirectly), were infrequently reported. Findings suggest a need for structural anti-discrimination interventions, in tandem with culturally congruent individual- or group-level interventions that aim to enhance men's existing adaptive coping strategies.
Full Text Available Background: HIV is associated with an increased risk of cardiovascular disease (CVD and related clinical events. While traditional risk factors play an important role in the pathology of cardiovascular disease, HIV infection and its sequelae of immune activation and inflammation may have significant effects on the myocardium before becoming clinically evident. Cardiac MRI (CMR can be used to detect the pattern of these subclinical changes. This will lead to a better understanding of risk factors contributing to cardiovascular disease prior to it becoming clinically significant in HIV-positive patients. Methods: Prospective cohort study of 127 asymptomatic HIV-positive men on ART compared to 35 matched controls. Baseline demographics, HIV parameters, 12-lead ECG, routine biochemistry, and traditional cardiovascular risk factors were recorded. Images were acquired on a 3T Achieva Philips MRI scanner with 5 channel phase array cardiac coil and weight-based IV gadolinium was given at 0.15 mmol/kg dose with post-contrast inversion recovery imaging after 10 minutes. Results: 6/127 (4.7% of asymptomatic HIV-positive men had late gadolinium enhancement (LGE on MRI verses 1/35 (2.9% in the control group. In 3/6 (50% of cases this was in a classical infarction pattern with subendocardial involvement. 3/6 (50% were consistent with prior myocarditis. There was no significant difference in mean LVEF (66.93% vs 65.18%, LVMI (60.05g/m2 vs 55.94g/m2 or posterolateral wall thickness (8.28 mm and 8.16 mm between cases and controls respectively. There was significantly more diastolic dysfunction, E:A ratio < 1, found in the HIV-positive group, 18% vs 7% of controls (p = 0.037. Framingham risk did not predict either of these outcomes. Conclusions: There is an increased incidence of LGE detected on CMR in this asymptomatic HIV-positive cohort. Two distinct pathological processes were identifed as causing these changes, myocardial infarction and myocarditis

This article explores the complex, dynamic and contextual frameworks within which men working in a mining community and their live-in long-term partners or spouses (termed "couples" in this study) respond to the introduction of HIV into their heterosexual relationships; the way in which partners adopt gendered positions in enabling them to make sense of their illness; how they negotiate their respective masculine and feminine roles in response to the need for HIV-related lifestyle changes; as well as the gendered nature of partner support in relation to antiretroviral therapy (ARV) adherence. We conducted an in-depth qualitative study with a sample of 12 HIV-positive seroconcordant heterosexual couples in a South African mining organization. Transcripts based on semi-structured couple's interviews were analyzed using an inductive emergent thematic analytical method. The findings present compelling evidence that the impact of HIV and AIDS is mitigated, in the main, by the nature of the dyadic relationship. Where power and agency were skewed in accordance with traditional gender scripts, the impact of HIV and AIDS was deleterious in terms of negotiating disclosure, meeting expectations of care and support, and promoting treatment adherence. As a corollary, the study also revealed that where the relational dynamic evidenced a more equitable distribution of power, the challenge of negotiating illness was embraced in a way that strengthened the couples' affiliation in profound ways, manifested not simply in a reduction in risk behaviours, but in both partner's courage to re-visit sensitive issues related to managing their relationship in the context of a debilitating illness. Gendered positioning (by self and others) was found to play a crucial role in the way couples experienced HIV and ARV treatment, and underscored the positive role of a couples-counselling approach in the negotiation of the illness experience. However, as part of a broader social project, the

As a corollary, the study also revealed that where the relational dynamic evidenced a more equitable distribution of power, the challenge of negotiating illness was embraced in a way that strengthened the couples’ affiliation in profound ways, manifested not simply in a reduction in risk behaviours, but in both partner's courage to re-visit sensitive issues related to managing their relationship in the context of a debilitating illness. Conclusions: Gendered positioning (by self and others was found to play a crucial role in the way couples experienced HIV and ARV treatment, and underscored the positive role of a couples-counselling approach in the negotiation of the illness

Adolescent boys and girls are disproportionately affected in the current HIV epidemic. Numerous sociobehavioral studies have addressed the indirect drivers surrounding this vulnerability-for example, socioeconomic, geographical locale, and all forms of violence. However, the direct factors that may influence infection, such as the anatomical and physiological maturation of the anogenital tracts of adolescents or the trauma and wound-healing processes of injured mucosal tissue, are understudied and represent a gap within the HIV prevention field. This article reviews the epidemiology of HIV infection and violence in adolescents and the available basic science knowledge attending this research area. More importantly, this review highlights the most critical gaps that need to be addressed to design preventive interventions that are safe and effective for this population, which is key to ending the HIV pandemic.

To determine factors associated with baseline neurocognitive performance in HIV-infected participants enrolled in the Strategies for Management of Antiretroviral Therapy (SMART) neurology substudy. Participants from Australia, North America, Brazil, and Thailand were administered a 5-test neurocognitive battery. Z scores and the neurocognitive performance outcome measure, the quantitative neurocognitive performance z score (QNPZ-5), were calculated using US norms. Neurocognitive impairment was defined as z scores penetration effectiveness rank of antiretroviral regimens were not. In this HIV-positive population with high CD4 cell counts, neurocognitive impairment was associated with prior CVD. Lower neurocognitive performance was associated with prior CVD, hypertension, and hypercholesterolemia, but not conventional HAD risk factors. The contribution of CVD and cardiovascular risk factors to the neurocognition of HIV-positive populations warrants further investigation.

Some 84,000 children with HIV/AIDS live in Côte d'Ivoire, where very little therapeutic or psychological help is available to them. The Yopougon Child Programme of the "Agence Nationale de Recherche sur le Sida" was launched in Abidjan in October 2000. It provides services for HIV-infected children and psychological consultations for children and their parents. This paper is about the psychosexual development of the HIV-positive adolescents in the Programme, 11 girls and 8 boys aged 13-17, their problems with HIV-related physiological and psychosexual changes, and relationships with their parents. The information was gathered in individual therapy sessions, group discussions and family support sessions. Bodily development was of major importance to these adolescents, particularly among those who had not yet developed secondary sexual characteristics and were shorter and weighed less than their peers. Those who had not achieved puberty were unable to participate in traditional rituals and worried whether they could ever marry or have children. In most cases, adolescents with HIV have been infected by a sexually transmitted virus without having had sexual relations themselves. They need support dealing with their sexual development and sexual feelings, along with medical care, in a context in which HIV infection is a secret, impossible to talk about with their peers.
To consider the extent to which those presenting for post-exposure prophylaxis (PEP) after sexual risk had been encouraged to do so by their PEP-aware partners with (diagnosed) HIV. Thirty men who had completed the 2005 UK Gay Men's Sex Survey who said they had ever tried to get PEP took part in a 30 minute telephone interview. Fifteen men in the sample described a sexual exposure incident where they had knowledge that their partner was diagnosed with having HIV. Of these, only five knew about their partner's HIV diagnosis prior to sexual contact. The remaining 10 sought PEP because their sexual partner revealed his positive status following potential sexual exposure. Our analysis revealed that word of mouth from friends, sexual partners and health professionals played a key role in men's knowledge about the existence of PEP. It is important for HIV and sexual health specialists to ensure that PEP information is not only targeted at those who are tested negative for HIV or are untested but also to people with diagnosed HIV.

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

Full Text Available Abstract Background and aims Quantitative tests of liver function (QTLF which are based on the hepatic metabolism or clearance of test substances have been successfully used to predict prognosis of a variety of different liver diseases. Still sufficient data in HIV-patients under anti-retroviral therapy (ART are lacking. Therefore, the aim of this prospective study was to investigate if and to what extent ART influences a broad panel of quantitative tests of liver function in patients with HIV-infection. Patients and methods Nineteen patients (14 males, 5 females, mean age 40 years with HIV-infection underwent QTLF including lidocaine half-life test (LHT, galactose elimination capacity (GEC, and indocyanine green clearance (IGC. These tests were performed before and 3 to 6 months after initiation of anti-retroviral therapy. Twenty age-matched healthy, medication-and virus-free adults served as controls. Results Lidocaine half-life was significantly lower in HIV-patients without ART. Combining anti-retroviral therapies shifted cytochrome p450 activity back into standard ranges. Galactose elimination capacity as a parameter of cytosolic liver function and indocyanine green clearance as a parameter of liver perfusion were not affected by ART. Conclusions QTLF may be a tool to predict prognosis or hepatic complications in HIV-infected patients with liver disease. Early determination of lidocaine half-life seems to be useful - this should be considered during the treatment of HIV-positive individuals.

The purpose of this study was to examine the association between perceived family support, either positive or negative, and adherence to antiretroviral medication regimens among HIV-positive individuals in the Kathmandu Valley, Nepal. We measured past 3-month antiretroviral adherence among 233 HIV-positive individuals, in relation to perceived family support, both positive (in terms of emotional and instrumental support) and negative (in the form of negative interactions), using the 10-item Nepali Family Support and Difficulty Scale. Medium and high levels of perceived emotional support from family were associated with reduced risk of antiretroviral nonadherence, compared with low levels of perceived emotional support (adjusted odds ratio [AOR] = 0.37, 95% confidence interval [CI] [0.16, 0.88], and AOR = 0.23, 95% CI [0.08, 0.64], respectively). Conversely, higher levels of felt emotional distance (AOR = 1.46, 95% CI [1.00, 2.14]) and experienced physical harm (AOR = 2.04, 95% CI [1.07, 3.91]) were associated with increased risk of nonadherence. The results support the recommendation that service providers need to be aware of the significant role of family support in shaping antiretroviral adherence and to consider ways to strengthen positive family support while minimizing negative family interactions to increase adherence rates. © The Author(s) 2015.

ambiente de apoio para essas mulheres e seus parceiros, propiciando às pessoas com HIV/Aids condições de conhecer, discutir e realizar opções conscientes no que concerne às decisões reprodutivas e sua sexualidade.OBJECTIVE: To assess sexual and reproductive health needs of HIV-positive women and factors that affect their access to prevention, safer sex practices and treatment and to appraise their ability of making informed choices concerning motherhood. METHODS: This exploratory study was conducted among women of an outpatient clinic in a reference center for STD/AIDS in the city of São Paulo, Brazil, in 1997. A consecutive non-probabilistic sample of 148 HIV-positive women was investigated. The exclusion criteria included those aged under 18 years and who were physically unable. Data were collected using structured interviews. Statistical analysis was performed using Chi-square test and t-test. RESULTS: The participants' mean age was 32 years old. As for education, 92 women (62.2% had completed elementary school and 12.2% had attended university. The median number of lifetime sexual partners was 4, and half of the interviewees were still sexually active after diagnosed HIV-positive. Of the total, 76% had children and 21% were still thinking about having children in future. Having many children, alive and living with their mothers were determinant factors for not wanting any more children. It was found no association between wanting children, risk perception, partner's serologic status, contraceptive use and other factors. After getting HIV infected, there was a substantial change in the contraceptive methods used. CONCLUSIONS: HIV infection did not change women's desire for having children. HIV-positive women's sexual and reproductive rights need to be discussed and respected in health care settings. Compliance to medication and safe sex practices are essential but difficult to meet requiring both counseling and support. Couples' counseling on reproductive

To compare the toxicity and treatment outcomes in human immunodeficiency virus (HIV)-positive versus HIV-negative patients with squamous cell carcinoma of the anal canal who underwent definitive concurrent chemoradiation at a single institution. Fifty-three consecutive HIV-positive patients treated between 1987 and 2013 were compared with 205 consecutive HIV-negative patients treated between 2003 and 2013. All patients received radiotherapy at a single regional facility. The median radiation dose was 54 Gy (range, 28 to 60 Gy). Concurrent chemotherapy consisted of 2 cycles 5-FU with mitomycin-C given on day 1±day 29). After treatment, patients were closely followed with imaging studies, clinical examinations, and rigid proctoscopies. Outcomes assessed were toxicity rates, progression-free survival, colostomy-free survival, cancer-specific survival, and overall survival. Median follow-up was 34 months. Compared with HIV-negative patients, HIV-positive patients were younger (median age, 48 vs. 62 y) and predominantly male sex (98% of HIV-positive patients were male vs. 22% of HIV-negative patients). Of the HIV-positive patients, 37 (70%) were on highly active antiretroviral therapy, 26 (65%) had an undetectable viral load at the time of treatment, and 36 (72%) had a CD4 count>200 (mean CD4 count, 455). There were no significant differences in acute or late nonhematologic or hematologic toxicity rates between the 2 groups. At 3 years, there was no significant difference between HIV-positive and HIV-negative patients in regards to progression-free survival (75% vs. 76%), colostomy-free survival (85% vs. 85%), or cancer-specific survival (79% vs. 88%, P=0.36), respectively. On univariate analysis, there was a trend toward worse overall survival in HIV-positive patients (72% vs. 84% at 3 y, P=0.06). For the entire cohort, on multivariate analysis only male sex and stage were predictive of worse survival outcomes. HIV status was not associated with worse outcomes in Cox

Although anti-HIV-1 protease drugs nelfinavir (NFV) and saquinavir (SQV) share common functional groups, D30N is a major resistance mutation against NFV but remains susceptible to SQV. We have determined the crystal structure of D30N mutant-tethered HIV-1 protease in complex with SQV to 1.79 Å resolution. Structural analysis showed that SQV forms two direct hydrogen bonds with the main chain atoms of the residues Asp29 and Asp30 that are not observed in the D30N-NFV complex. Apart from maintaining these two main chain hydrogen bonds, the P2-asparagine of SQV forms an additional hydrogen bond to the mutated side chain of the residue 30. These could be the reasons why D30N is not a drug resistance mutation against SQV. This structure supports the previous studies showing that the interactions between a potential inhibitor and backbone atoms of the enzyme are important to maintain potency against drug-resistant HIV-1 protease. © 2014 John Wiley & Sons A/S.

HIV-positive women who have sex with women (WSW) have been overlooked by government researchers, health care providers and the AIDS service community. In addition to stigmas against homosexuality and HIV in larger society, low-income, African-American and Latina HIV-positive WSWs face culturally-based stigmas and are disproportionately affected by poverty, drug addiction, homelessness, sex work and abuse. Through an analysis of sixteen intensive interviews with low-income HIV-positive WSWs of color, I critically examine the physical, emotional and psychological needs of this population and their methods of coping with HIV.

Non-enterococcal Gram-positive bacteria that are intrinsically vancomycin-resistant have been infrequently isolated in association with serious infections. However, well-documented infections have lately been reported with increasing frequency. Because these organisms may be pathogens, we tested the MICs of 19 antimicrobial agents by the agar dilution method for predicting susceptibility. The activity of these antimicrobial agents was assessed against 28 strains (Lactobacillus rhamnosus, 6; Lactobacillus acidophilus, 1; Lactobacillus casei, 1; Lactobacillus fermentum, 2; Lactobacillus brevis, 1; Lactobacillus plantarum, 1; Weissella confusa, 2; Leuconostoc mesenteroides, 7; Leuconostoc lactis, 4; Pediococcus acidilactici, 2; Pediococcus pentosaceus, 1), isolated from clinical specimens in an Argentinian university hospital from 1997 to 2003. The MICs of penicillin for 67% of the Lactobacillus strains and 100% of the Leuconostoc spp. and Pediococcus spp. strains tested were in the 0.25-2 microg/mL range. Erythromycin was the most active antimicrobial overall. Multiresistance was observed in 2 strains (Lactobacillus rhamnosus, 1; Lactobacillus plantarum, 1).

Many HIV-positive people who inject drugs (PWID) globally are not receiving HIV care. This represents a major challenge among key populations to end the global HIV epidemic. This qualitative study explored the process and associated barriers of linking HIV-positive PWID who are in addiction treatment to HIV care in St. Petersburg, Russia. We conducted three focus groups and seven semi-structured interviews with participants in the LINC ("Linking Infectious and Narcology Care") project at addiction and HIV hospitals in St. Petersburg. The sample consisted of 25 HIV-infected patients with opioid dependence and seven health-care providers, including addiction and infectious disease physicians and case managers. A variety of intertwining factors influence effective engagement of PWID with HIV treatment. Stigma, problematic patient-provider relationships, and fragmented health care were the main challenges for HIV care initiation by PWID, which were further exacerbated by injection drug use. Effective linkage of PWID to HIV care requires acknowledging and addressing stigma's role and different perspectives of patients and providers.

Female cross-border migrants experience elevated risks for HIV, and migrants in South Africa may face additional risks due to the country's underlying HIV prevalence. These risks may be mitigated by the receipt of social support. A behavioral risk-factor survey was administered using respondent-driven sampling. Multivariable regression models assessed the relationships between social support and two HIV outcomes: HIV serostatus and perceived HIV status. Low social support was not significantly associated with HIV status (aOR = 1.03, 95 % CI 0.43-2.46), but was significantly related to a perception of being HIV positive (aPR = 1.36, 95 % CI 1.04-1.78). Age, marital status, and education level were significantly associated with HIV serostatus. Illegal border-crossing, length of time in South Africa, anal sex, and transactional sex were significantly associated with aperception of being HIV positive. Future research should investigate how HIV risks and the receipt of social support change throughout the migration process.

The infection routes of HIV-1 can affect several viral properties, including dissemination, pathogenesis, and immune evasion. In this study, we evaluated the inhibitory activity of a wide variety of anti-HIV drugs, focusing on the impact that different infection pathways have on their efficacy. Compared to cell-free infection, inhibitory activities were reduced in cell-to-cell productive transmission for all drugs tested. We detected weak reporter-expressing target cells after cell-to-cell transmission in the presence of integrase strand transfer inhibitors (INSTIs). Further analysis revealed that this expression was mainly due to unintegrated circular HIV (cHIV) DNAs, consisting of 1-LTR and 2-LTR circles. When in vitro-constructed cHIV DNAs were introduced into cells, the production of infectious and intercellular transmittable virions was observed, suggesting that cHIV DNA could be a source of infectious virus. These results highlight some advantages of the cell-to-cell infection mode for viral expansion, particularly in the presence of anti-retroviral drugs. Copyright © 2015 Elsevier Inc.

Little is known about fertility choices and pregnancy outcome rates among HIV-infected women in the current combination antiretroviral treatment era. We sought to describe trends and factors associated with live-birth and abortion rates among HIV-positive and high-risk HIV-negative women enrolled in the Women's Interagency HIV Study in the United States. We analyzed longitudinal data collected from Oct. 1, 1994, through Sept. 30, 2012, through the Women's Interagency HIV Study. Age-adjusted rates per 100 person-years live births and induced abortions were calculated by HIV serostatus over 4 time periods. Poisson mixed effects models containing variables associated with live births and abortions in bivariable analyses (P live birth increased from 1994 through 1997 to 2006 through 2012 (2.85-7.27/100 person-years, P trend live-birth rates occurred among HIV-positive compared to HIV-negative women in 1994 through 1997 and 1997 through 2001, however rates were similar during 2002 through 2005 and 2006 through 2012. Higher CD4+ T cells/mm3 (≥350 adjusted incidence rate ratio, 1.39 [95% CI 1.03-1.89] vs live-birth rates, while combination antiretroviral treatment use (adjusted incidence rate ratio, 1.35 [95% CI 0.99-1.83]) was marginally associated with increased live-birth rates. Younger age, having a prior abortion, condom use, and increased parity were associated with increased abortion rates among both HIV-positive and HIV-negative women. CD4+ T-cell count, combination antiretroviral treatment use, and viral load were not associated with abortion rates. Unlike earlier periods (pre-2001) when live-birth rates were lower among HIV-positive women, rates are now similar to HIV-negative women, potentially due to improved health status and combination antiretroviral treatment. Abortion rates remain unchanged, illuminating a need to improve contraceptive services. Copyright © 2016 Elsevier Inc. All rights reserved.

Access to substance use disorder (SUD) treatment is a critical issue for women with HIV. This study examined differences in SUD diagnoses, comorbid psychiatric diagnoses, and predictors of SUD treatment initiation among a racial/ethnically diverse sample of HIV-positive women (N=228) and a demographically similar cohort of HIV-negative women (N=693). Diagnoses and service utilization data were obtained from electronic health records of members of a large integrated healthcare system in Northe...

Critical to preventing the spread of HIV is promoting condom use among HIV-positive individuals. Previous studies suggest that gender norms (social and cultural constructions of the ways that women and men are expected to behave) may be an important determinant of condom use. However, the relationship has not been evaluated among HIV-positive women and men in South Africa. We examined gender norms and condom use at last sex among 550 partnerships reported by 530 sexually-active HIV-positive w...
Full Text Available Aim: The aim of this study was to identify the personality traits of alcohol and human immunodeficiency virus (HIV-positive patients and to compare them with normal controls. Materials and Methods: This cross-sectional study included 100 consecutive patients with alcohol dependence and HIV each and a control group of 100 normal cases without any physical or psychiatric illness. A score of 2 or less on the General Health Questionnaire was taken as cutoff, and the participants were included in the study with written informed consent. All participants were assessed with the NEO personality inventory revised and sensation-seeking scale (SSS. Results: There were significant differences among the study group on all the five factors, i.e., neuroticism (N, extraversion (E, conscientiousness (C, openness to experience (O, and agreeableness (A. On factor “N,” HIV and alcohol group scored significantly more as compared to normal group. Odds ratio revealed high neuroticism to be a risk factor in alcohol-dependent and HIV cases (P < 0.05. The normal group scored significantly higher on factor “E” as compared to HIV and alcohol cases. High scores on factor “E” and “C” have a protective. Odds ratio found low score of factor “C” as a risk factor; however, “O” did not emerge as a risk factor. The logistic regression revealed that high scores on “N” and “E” and low “A” score had a significant association with alcohol dependence (P < 0.05. Among HIV cases, high score on “N” and “E” and low “C” score emerged significant. Alcohol cases scored significantly more on boredom susceptibility (BS on SSS as compared to HIV and normal controls. On disinhibition (DIS, HIV cases and alcohol cases scored significantly higher as compared to normal group (P < 0.05. Conclusion: High “N” scores on NEO personality inventory are significantly associated with alcohol dependence and HIV while high scores on “E” and “C” have a

BACKGROUND: Clinical guidelines recommend immediate initiation of combined antiretroviral therapy for all HIV-positive individuals. However, those guidelines are based on trials of relatively young participants. METHODS: We included HIV-positive antiretroviral therapy-naive, AIDS-free individuals aged 50-70 years after 2004 in the HIV-CAUSAL Collaboration. We used the parametric g-formula to estimate the 5-year risk of all-cause and non-AIDS mortality under (1) immediate initiation at baselin...

HIV-positive women are infected with human papillomavirus (HPV) (especially with multiple types), and develop cervical intraepithelial neoplasia (CIN) and cervical cancer more frequently than HIV-negative women. We compared HPV DNA prevalence obtained using a GP5+/6+ PCR assay in cervical exfoliated cells to that in biopsies of 468 HIV-positive women from Nairobi, Kenya. HPV prevalence was higher in cells than biopsies and the difference was greatest in 94 women with a combination normal cyto...
