Estimates of global, regional, and national incidence, prevalence, and mortality of HIV, 1980-2015: the Global Burden of Disease Study 2015

Global and national guidance for the use of pre-exposure prophylaxis during peri-conception, pregnancy and breastfeeding

Pre-exposure prophylaxis (PrEP) is a well-established biomedical HIV prevention strategy and recommended to reduce HIV risk during peri-conception, pregnancy and breastfeeding. Efforts are needed to translate global recommendations into national guidelines and implementation strategies. This article presents the current status of policy guidance for the use of PrEP during peri-conception, pregnancy and breastfeeding, with a particular focus on high prevalence countries, including those in sub-Saharan Africa. PrEP clinical guidelines released by ministries of health or other national-level health bodies, with a particular focus on recommendations for PrEP use during peri-conception, pregnancy and breastfeeding, were reviewed and summarised. Among countries with PrEP guidelines and/or policy, pregnancy is recognised as a period with increased HIV vulnerability, and some recommend PrEP use specifically during pregnancy. Only one country notes that PrEP is contraindicated during pregnancy, recognising a gap in complete safety data from women using PrEP throughout pregnancy. PrEP is not contraindicated as a peri-conception HIV prevention strategy in any country, but only three countries have specific guidance for peri-conception HIV prevention. Multiple barriers to the implementation of PrEP during pregnancy and breastfeeding are discussed, including barriers at the policy, health systems, social and personal levels. Although pregnancy is a period of heightened risk and fertility rates are high in many settings with high HIV burden, few PrEP policies have included guidance for PrEP use specific to peri-conception, pregnancy and breastfeeding periods. This gap can be overcome by the development or adoption of national clinical guidelines and implementation strategies from exemplary countries.

Morphological analysis of the skeletal development in lateral cephalometric radiographs of HIV infected children ongoing Highly Active Antiretroviral Therapy

Background

To investigate the skeletal development of HIV infected children through a morphological analysis of the cervical vertebrae (CV) in lateral cephalometric radiographs.

Material and Methods

The sample consisted of 86 lateral cephalometric radiographs of male and female children aged between 6 and 14 years old. The radiographs were equally distributed in groups 1 (HIV infected children) and 2 (non-infected children, paired by sex and age). Two examiners analyzed the CV according to the method of Hassel and Farman (1995). Spearman correlation coefficient was used to associate age and skeletal development within groups, while Mann-Whitney test compared the skeletal development between groups.

Results

The correlation of age and skeletal development in group 1 reached 0.17, 0.27 and 0.27 (p >0.05) for C2, C3 and C4, respectively, while in group 2 it reached 0.65, 0.54 and 0.60, respectively (p <0.001). Differences were not significant between groups (p >0.05).

Conclusions

HIV infected and non-infected children showed a similar development of the CV. However, the weak correlation between age and CV development in HIV infected children highlights the need for careful decisions prior to therapeutic approaches – especially those founded on the prediction of skeletal development, such as maxillofacial surgeries, and orthopedic and orthodontic procedures.

Rate of cardiovascular, renal and bone disease and their major risks factors in HIV-infected individuals on antiretroviral therapy in Spain

BACKGROUND

The life expectancy of HIV-infected individuals has dramatically improved with potent antiretroviral therapies. However, organ-specific toxicities of some antiretrovirals and persistent inflammation and immune activation due to residual virus replication account for a high burden of age-associated comorbidities in the HIV population.

METHODS

The prevalence of overt cardiovascular, renal and bone diseases as well as their major risk factors were cross-sectionally examined during the year 2014 in the VACH cohort, a large nationwide population of HIV-infected individuals in Spain.

RESULTS

A total of 10,897 HIV-infected patients were examined. Seventy-one point four percent were male and the mean age was 48 years. Mean time since HIV diagnosis was 15.8 years and mean time on antiretroviral therapy was 13.1 years. The proportion of patients with undetectable viral load was 87.1%, whereas 65.7% had CD4 counts>500 cells/mm³. Overall, cardiovascular, renal and bone disease were recorded in 4.7%, 5.9% and 2.8%, respectively. The prevalence of major risk factors was as follows: smoking 51.3%, alcohol abuse 7.8%, overweight/obesity 42.2%, diabetes 19.9%, dyslipidaemia 72.6%, hypertension 25.6%, and osteoporosis 11.1%. In the subset of patients older than 55 years-old (18%), all figures for overt disease and their major risk factors were significantly greater.

CONCLUSION

Major age-related medical conditions and most of their risk factors are highly prevalent in HIV-infected individuals on long-term antiretroviral therapy in Spain. Preventive actions, including careful selection of antiretroviral agents, should be prioritized in the ageing HIV population.

Analysis of drug resistance in HIV protease

BACKGROUND

Drug resistance in HIV is the major problem limiting effective antiviral therapy. Computational techniques for predicting drug resistance profiles from genomic data can accelerate the appropriate choice of therapy. These techniques can also be used to select protease mutants for experimental studies of resistance and thereby assist in the development of next-generation therapies.

RESULTS

The machine learning produced highly accurate and robust classification of HIV protease resistance. Genotype data were mapped to the enzyme structure and encoded using Delaunay triangulation. Generative machine learning models trained on one inhibitor could classify resistance from other inhibitors with varying levels of accuracy. Generally, the accuracy was best when the inhibitors were chemically similar.

CONCLUSIONS

Restricted Boltzmann Machines are an effective machine learning tool for classification of genomic and structural data. They can also be used to compare resistance profiles of different protease inhibitors.

Mother-baby dyads enrolled in PMTCT care in western Kenya: characteristics and implications for ART programmes

The objective of the study was to establish the mother-baby pair characteristics that contribute to vertical transmission of HIV and elucidate on remediation. We assessed for factors increasing the odds of HIV transmission in children born to HIV-infected mothers in western Kenya. We used a retrospective study which reviewed routinely collected data of 1 028 mother-baby pairs enrolled in a prevention of mother-to-child transmission (PMTCT) programme in western Kenya from January to December 2015. We compared the transmission rates amongst mothers known to have a positive HIV status before conception (known positives/KPs) versus the transmission amongst those who were newly diagnosed during maternal and child health (MCH) clinic attendance (new positives/NPs). We compared the socio-demographic and clinical characteristics of the mothers using chi square and Kruskal-Wallis tests at 95% confidence interval (CI). We assessed for factors associated with the infants' HIV status using a logistic regression model. The results revealed that 60% (622) of the mothers were KPs, and that KPs and NPs had mother-to-child transmission (MTCT) rates of 5.5% and 20.7% respectively. Close to 90% of the NP Mothers were at an early HIV clinical stage at enrolment and 40% were enrolled after delivery. The infants of NPs were enrolled at a mean age of 18.3 weeks compared to 6.6 weeks for the infants of the KPs. On adjusted multivariable analysis, child's age at enrolment (AOR = 1.05, 95%CI = 1.036-1.064) and mother's status at conception (AOR = 1.96, 95%CI = 1.042-3.664) were significantly associated with the infant's HIV status. None of the HIV infected infants had received nevirapine prophylaxis. Most of the mothers enrolling into the PMTCT programme have a known HIV-positive status, however, NPs are the largest contributors to continued MTCT.

Comparison of Zidovudine and Tenofovir Based Regimens With Regard to Health-Related Quality of Life and Prevalence of Symptoms in HIV Patients in a Kenyan Referral Hospital

Aim: Zidovudine and tenofovir form the backbone of antiretroviral therapy in Kenya. However, their side-effects may affect the quality of life (QoL) of patients. The aim was to compare the health-related quality of life (HRQoL) of adult patients on tenofovir versus zidovudine based regimens in a referral hospital in Kenya to provide future guidance.

Methods: A comparative cross sectional study among 501 adult out-patients on either tenofovir or zidovudine was undertaken in Kenyatta National Hospital between 2015 and 2016. The Medical Outcome Study HIV Health Survey (MOS-HIV) was administered along with other key aspects of treatment. Linear regression analysis was performed to identify determinants of HRQoL.

Results: Patients on zidovudine had a higher Physical Health Summary Score (PHSS) and Mental Health Summary Score (MHSS) compared to those on tenofovir. The presence of any symptom of the disease and a stated inability to cope were negatively associated with PHSS, whilst having a regular source of income improved PHSS. Being on tenofovir, symptom of illness [β = -1.24; 95% CI (-2.253, -0.226)], absence of pain [β=0.413; 95% CI (0.152, 0.674)] and patient stated inability to cope with HIV [β = -1.029; 95% CI (-1.441, -0.617)] affected the MHSS. Patients on tenofovir and second line regimens had more signs and symptoms of illness.

Conclusion: Participants on zidovudine based regimens showed a better performance across all aspects of HRQoL. These are considerations for the future.

Global research output on HIV/AIDS-related medication adherence from 1980 to 2017

BACKGROUND

"Human Immunodeficiency Virus (HIV)" and Acquired Immunodeficiency Syndrome (AIDS) are global health burden. Medication adherence in people living with HIV (PLWH) is a key element in reducing morbidity and mortality. Quantitative and qualitative assessment of research activity helps identify research gaps as well as efforts implemented to improve adherence behaviors in PLWH. The aim of the current study was to assess and analyze literature on HIV/AIDS-related medication adherence using bibliometric methods.

METHODS

SciVerse Scopus was used to accomplish the purpose of the current study. The study period included all times up to 2017. The analysis was restricted to documents published in academic journals.

RESULTS

Search strategy retrieved 3021 documents with an average of 32.5 citations per document, an h-index of 136, and an average of 4.4 authors per documents. The volume of literature on HIV/AIDS-related medication adherence constituted 1.3% of the overall HIV/AIDS literature. There was a significant (p < 0.01; r = 0.9) correlation between the growth of publications in AIDS-related stigma and medication adherence. The regions of America (567.9) had the highest research output per one million infected people (567.9) followed by the European region (314.3), Western Pacific Region (70.7), Eastern Mediterranean region (31.4), South East Asia (34.0), and Africa (19.3). Geographical distribution of publications showed an active contribution of certain countries in the Southern and Eastern region of Sub-Saharan Africa. Harvard University (8.4%; n = 254) was the most active institution. The top cited documents focused on the impact of adherence on disease outcome and the impact of text messages on improving medication adherence.

CONCLUSION

Research on medication adherence in PLWH showed regional variations. International research collaboration with high burden regions such as Sub-Saharan Africa needs to be strengthened to achieve the global target of ending AIDS as a public health threat by 2030.

Autoimmune Kidney Diseases Associated with Chronic Viral Infections

Autoimmune kidney diseases triggered by viruses are an important cause of kidney disease in patients affected by chronic viral infection. Hepatitis B virus (HBV) infection is associated with membranous nephropathy and polyarteritis nodosa. Hepatitis C virus (HCV) infection is a major cause of cryoglobulinemic glomerulonephritis. Patients with human immunodeficiency virus (HIV) may develop HIV-associated nephropathy, a form of collapsing focal segmental glomerulosclerosis, or various forms of immune-complex-mediated kidney diseases. This article summarizes what is known about the pathogenesis, diagnosis, and management of immune-mediated kidney diseases in adults with chronic HBV, HCV, and HIV infections.

Lysine-specific demethylase 1 cooperates with BRAF-histone deacetylase complex 80 to enhance HIV-1 Tat-mediated transactivation

Despite the notable success of combination antiretroviral therapy, how to eradicate latent HIV-1 from reservoirs poses a challenge. The Tat protein plays an indispensable role in HIV reactivation and histone demethylase LSD1 promotes Tat-mediated long terminal repeats (LTR) activation. However, the role of LSD1 in remodeling chromatin and the role of its component BHC80 in activation of latent HIV-1 in T cells are unknown. Our findings indicate that LSD1 could decrease the level of histone H3 lysine 4 trimethylation (H3K4me3) at the HIV-1 promoter by recruiting histone lysine demethylase 5A (KDM5A) and preventing histone methyltransferase Set1A and WD-40 repeat protein 5 (WDR5) from binding to LTR. Moreover, BHC80 is necessary for LSD1-triggered LTR activation and assists LSD1 in activating LTR by binding to nucleotides 305-631 of LTR. In activated J-Lat-A2 cells, BHC80 expression was elevated and its isoform BHC80-6 promoted the association of BHC80 with LSD1. These results suggest that the LSD1-BHC80 complex enhances HIV-1 transcription by a decrease of H3K4me3 level at the viral promoter. Therefore, it might be used as a new drug target to reactivate latent HIV-1.

Epidemiological metrics and benchmarks for a transition in the HIV epidemic

Peter Godfrey-Faussett and colleagues present six epidemiological metrics for tracking progress in reducing the public health threat of HIV.

Prevalence of Chronic Kidney Disease and Poor Diagnostic Accuracy of Dipstick Proteinuria in Human Immunodeficiency Virus-Infected Individuals: A Multicenter Study in Japan

BACKGROUND

Chronic kidney disease (CKD) has become one of the common comorbid conditions affecting the human immunodeficiency virus (HIV) population. Human immunodeficiency virus-infected individuals are at increased risk of developing CKD, and they are likely to experience faster progression of renal dysfunction compared with HIV-uninfected individuals. Albuminuria represents not only kidney damage but also manifests metabolic syndrome and vascular dysfunction.

METHODS

We conducted a multicenter, cross-sectional study involving 2135 HIV-infected individuals in Japan to test the prevalence of CKD and proteinuria/albuminuria. Urine sample was analyzed by both dipstick test and albumin-to-creatinine ratio (ACR) assay. Chronic kidney disease was classified according to the Kidney Disease Outcomes Quality Initiative (K/DOQI) and Kidney Disease: Improving Global Outcomes (KDIGO) guidelines. The diagnostic performance of dipstick test to detect albuminuria (ACR ≥30 mg/g) was evaluated.

RESULTS

The prevalence of CKD, evaluated by K/DOQI and KDIGO guidelines, was 15.8% and 20.4%, respectively. Age, total cholesterol level, prevalence of hypertension, diabetes mellitus, and hepatitis C infection tended to increase, whereas levels of hemoglobin, serum albumin, and CD4 cell count tended to decrease as CKD risk grades progressed. Proteinuria and albuminuria were present in 8.9% and 14.5% of individuals, respectively. Dipstick test ≥1+ to detect albuminuria had an overall sensitivity of 44.9% and specificity of 97.2%.

CONCLUSIONS

The KDIGO guideline may enable physicians to capture HIV-infected patients at increased risk more effectively. The sensitivity of dipstick proteinuria to detect albuminuria is so poor that it may not serve as an alternative in HIV-infected individuals.

The metabolic syndrome and renal function in an African cohort infected with human immunodeficiency virus

INTRODUCTION

The human immunodeficiency virus (HIV) is often accompanied by renal dysfunction. It is expected that metabolic syndrome (MetS) may exacerbate renal impairment.

OBJECTIVE

We therefore determined the prevalence of MetS and the association thereof with renal function in a South African cohort infected with HIV.

METHODS

We matched 114 HIV-infected (77.3% on antiretroviral therapy [ART] and 22.7% ART-naïve) and 114 HIV-uninfected individuals according to age, sex and locality. We examined cardiovascular, anthropometric and metabolic measurements and determined the MetS. Renal function was assessed using standardised procedures.

RESULTS

The prevalence of MetS was lower in the HIV-infected individuals as compared to the uninfected individuals (28% vs. 44%, p = 0.013). The HIV-infected group presented with a lower body mass index (BMI) and waist circumference (WC) (all p < 0.001), as well as blood pressure (BP) (p ≤ 0.0021). The results were confirmed when comparing the HIV-infected group using ART (N = 85) and the HIV-uninfected group. When comparing the HIV-infected individuals with MetS to the HIV-uninfected individuals with MetS, no differences in BP were seen. With regard to renal function, the HIV-infected individuals with MetS (n = 32) had 43% higher urinary albumin-creatinine ratio (uACR) compared to the HIV-uninfected individuals with MetS, after adjusting for age, sex and WC (p = 0.032). None of the other renal function markers differed after adjustments for WC or BMI.

CONCLUSION

The HIV-infected Africans with MetS had almost twofold higher uACR, despite the low prevalence of MetS, compared to their uninfected counterparts. The combination of HIV and MetS seemed to increase the risk for renal impairment.

Gender disparity in epidemiological trend of HIV/AIDS infection and treatment in Ethiopia

Background

The HIV/AIDS epidemic has been fuelled by gender inequality and disparity resulted in violation of women reproductive right. The “feminization” of the pandemic is more apparent in Sub-Saharan Africa where the larger numbers of HIV infected people are living. Although they carry the higher proportion of HIV cases; access to care and treatment is lower among women. In Ethiopia where HIV is prevalent and gender violence is common, the disparity may be higher. Therefore, this research aimed to assesses trends in gender disparity in the HIV/AIDS epidemic in Ethiopia to bring evidence for action.

Methods

This study was conducted using aggregates of HIV/AIDS indicator data from 1990 to 2016 of UNAIDS data bases. The data was compiled and analyzed with excel and STATA Version 11. The trend was assessed, gender difference was measured and rate of change was compared between genders and specific age groups.

Result

Adult females (age 15+) accounted 61.5% of the HIV cases and new infection among adults. While, adolescent females (age 10-19) and young women (age 15-24) accounted 52.3 and 57.5% of prevalent cases and 74 and 68% of new infection in their age category respectively. HIV is 1.62 times more prevalent among adult women than men. Since 1990, HIV cases among adults has risen markedly in the first decade with 24 and 20%, then declined by 41.5% in the second decade and rose again by 5 and 8.7% among women and men respectively. The overall prevalence is declined by 72.4 and 71.5% from the maximum record. Women and men have equal access for ART; 62% of men and 61% of women from all adults living with HIV were on ART. While 61% of deaths were among adult women and the death rate is similar among adolescent women and men. AIDS- related death has been declined by 76% from the maximum record.

Conclusion

HIV/AIDS prevalence, new infection and AIDS-related death are by far higher among adult women than men. While the coverage of treatment and HIV care is equal among both genders. Vulnerable age groups (adolescent females and young women) take the lion’s share of the new infections and prevalent cases. Therefore due attention is needed to avert gender disparity with a particular emphasis for adolescents and young women.

Morbidity benefit conferred by childhood immunisation in relation to maternal HIV status: a meta-analysis of demographic and health surveys

The study determined the prevalence of acute respiratory infections and diarrhoea among sub-Saharan African children. It also examined if there was any significant morbidity benefit conferred by three doses of diphtheria-tetanus-pertussis containing vaccines (DTP3) with respect to maternal HIV status. Data were obtained from the Demographic and Health Survey (DHS) program, United Nations Development Programs, World Bank and Joint United Nations Programme on HIV/AIDS. Pooled odds ratio (OR) and 95% confidence intervals (CI) were calculated for the countries. Test of heterogeneity, sensitivity analyses and meta-regression were also conducted. The prevalence of acute respiratory infections and diarrhoea were similar between the children that were vaccinated and those who were not vaccinated with DTP3. The pooled result shows that children who did not receive DTP3 were more likely to have symptoms of acute respiratory infections than children who had DTP3 (OR 1.09, 95% CI 1.02 to 1.17); with low heterogeneity across the countries. The combined result for diarrhoea shows that children who did not receive DTP3 were less likely to have episodes of diarrhoea than children who received DTP3 (OR 0.83, 95% CI 0.74 to 0.92); with substantial heterogeneity across the countries. There was no difference between the estimates of DTP3 vaccinated and unvaccinated children of HIV seropositive mothers with respect to symptoms of acute respiratory infections or episodes of diarrhoea. Tackling various causes and risk factors for respiratory tract infections and diarrhoeal diseases should be a priority for various stakeholders in sub-Saharan Africa.

Modulatory Effects of Nicotine on neuroHIV/neuroAIDS

Nicotine, one of the key active ingredients in tobacco smoke, exerts its effects via binding to nicotinic acetylcholine receptors (nAChRs). Although both negative and positive pharmacological effects of nicotine have been shown in numerous animals and human studies, its interaction with human immunodeficiency virus-1 (HIV-1) have not been fully elucidated. Even though combined anti-retroviral therapy (cART) limits the progression of HIV-1 to acquired immune deficiency syndrome (AIDS), HIV-associated neurocognitive disorders (HAND) remain prevalent. There is thus a compelling need to enhance our understanding of HAND-related neurologic dysfunction. Some biochemical pathways and physiological dysfunctions have been found to be shared by HAND and Alzheimer's (AD) or Parkinson's (PD) diseases, and nicotine may exert the same neuroprotection in HAND that has been observed in both AD and PD. In the past dozen years, various potential therapeutic effects of nicotine such as neuroprotection have been revealed in both in vivo and in vitro studies, including using HIV-1 transgenic (HIV-1Tg) rat model, which mimics HIV-infected patients receiving cART. In the current review, we describe recent progress in the prevalence of HIV/AIDS with and without cigarette smoking, some animal models for studying neural dysfunction associated with HIV-1 infection, elucidating the modulatory effects of cigarette smoking/nicotine on HIV/AIDS, the anti-inflammatory effects of nicotine, and the neuroprotective effects observed in HIV-1Tg rat model. Taken together, these findings suggest the following: although tobacco smoking does cause deleterious effects in both health and disease conditions such as HIV infection, nicotine, the significant component of tobacco smoke, has been shown to possess some neuroprotective effects in HIV patients, possible via its anti-inflammatory activities. It is therefore necessary to study nicotine's dual effects on neuroHIV/neuroAIDS in hope of better defining the potential medical uses of nicotine or its analogues, and to make them available in a purer and less dangerous form.

Global Burden of Atherosclerotic Cardiovascular Disease in People Living With HIV: Systematic Review and Meta-Analysis

BACKGROUND

With advances in antiretroviral therapy, most deaths in people with HIV are now attributable to noncommunicable illnesses, especially cardiovascular disease. We determine the association between HIV and cardiovascular disease, and estimate the national, regional, and global burden of cardiovascular disease attributable to HIV.

METHODS

We conducted a systematic review across 5 databases from inception to August 2016 for longitudinal studies of cardiovascular disease in HIV infection. A random-effects meta-analysis across 80 studies was used to derive the pooled rate and risk of cardiovascular disease in people living with HIV. We then estimated the temporal changes in the population-attributable fraction and disability-adjusted life-years (DALYs) from HIV-associated cardiovascular disease from 1990 to 2015 at a regional and global level. National cardiovascular DALYs associated with HIV for 2015 were derived for 154 of the 193 United Nations member states. The main outcome measure was the pooled estimate of the rate and risk of cardiovascular disease in people living with HIV and the national, regional, and global estimates of DALYs from cardiovascular disease associated with HIV.

RESULTS

In 793 635 people living with HIV and a total follow-up of 3.5 million person-years, the crude rate of cardiovascular disease was 61.8 (95% CI, 45.8-83.4) per 10 000 person-years. In comparison with individuals without HIV, the risk ratio for cardiovascular disease was 2.16 (95% CI, 1.68-2.77). Over the past 26 years, the global population-attributable fraction from cardiovascular disease attributable to HIV increased from 0.36% (95% CI, 0.21%-0.56%) to 0.92% (95% CI, 0.55%-1.41%), and DALYs increased from 0.74 (95% CI, 0.44-1.16) to 2.57 (95% CI, 1.53-3.92) million. There was marked regional variation with most DALYs lost in sub-Saharan Africa (0.87 million, 95% CI, 0.43-1.70) and the Asia Pacific (0.39 million, 95% CI, 0.23-0.62) regions. The highest population-attributable fraction and burden were observed in Swaziland, Botswana, and Lesotho.

CONCLUSIONS

People living with HIV are twice as likely to develop cardiovascular disease. The global burden of HIV-associated cardiovascular disease has tripled over the past 2 decades and is now responsible for 2.6 million DALYs per annum with the greatest impact in sub-Saharan Africa and the Asia Pacific regions.

The impact of lay counselors on HIV testing rates: quasi-experimental evidence from lay counselor redeployment in KwaZulu-Natal, South Africa

OBJECTIVES

This study aimed to determine the causal effect of the number of lay counselors removed from a primary care clinic in rural South Africa on the number of clinic-based HIV tests performed.

DESIGN

Fixed-effects panel analysis.

METHODS

We collected monthly data on the number of lay counselors employed and HIV tests performed at nine primary care clinics in rural KwaZulu-Natal from January 2014 to December 2015. Using clinic-level and month-level fixed-effects regressions, we exploited the fact that lay counselors were removed from clinics at two quasi-random time points by a redeployment policy.

RESULTS

A total of 24 526 HIV tests were conducted over the study period. Twenty-one of 27 lay counselors were removed across the nine clinics in the two redeployment waves. A 10% reduction in the number of lay counselors at a clinic was associated with a 4.9% [95% confidence interval (CI) 2.8-7.0, P < 0.001] decrease in the number of HIV tests performed. In absolute terms, losing one lay counselor from a clinic was associated with a mean of 29.7 (95% CI 21.2-38.2, P < 0.001) fewer HIV tests carried out at the clinic per month.

CONCLUSION

This study provides some evidence that lay counselors play an important role in the HIV response in rural South Africa. More broadly, this analysis adds some empirical support to plans to increase the involvement of lay health workers in the HIV response.

Progress toward eliminating TB and HIV deaths in Brazil, 2001-2015: a spatial assessment

BACKGROUND

Brazil has high burdens of tuberculosis (TB) and HIV, as previously estimated for the 26 states and the Federal District, as well as high levels of inequality in social and health indicators. We improved the geographic detail of burden estimation by modelling deaths due to TB and HIV and TB case fatality ratios for the more than 5400 municipalities in Brazil.

METHODS

This ecological study used vital registration data from the national mortality information system and TB case notifications from the national communicable disease notification system from 2001 to 2015. Mortality due to TB and HIV was modelled separately by cause and sex using a Bayesian spatially explicit mixed effects regression model. TB incidence was modelled using the same approach. Results were calibrated to the Global Burden of Disease Study 2016. Case fatality ratios were calculated for TB.

RESULTS

There was substantial inequality in TB and HIV mortality rates within the nation and within states. National-level TB mortality in people without HIV infection declined by nearly 50% during 2001 to 2015, but HIV mortality declined by just over 20% for males and 10% for females. TB and HIV mortality rates for municipalities in the 90th percentile nationally were more than three times rates in the 10th percentile, with nearly 70% of the worst-performing municipalities for male TB mortality and more than 75% for female mortality in 2001 also in the worst decile in 2015. The same municipality ranking metric for HIV was observed to be between 55% and 61%. Within states, the TB mortality rate ratios by sex for municipalities in the worst decile versus the best decile varied from 1.4 to 2.9, and HIV varied from 1.4 to 4.2. The World Health Organization target case fatality rate for TB of less than 10% was achieved in 9.6% of municipalities for males versus 38.4% for females in 2001 and improved to 38.4% and 56.6% of municipalities for males versus females, respectively, by 2014.

CONCLUSIONS

Mortality rates in municipalities within the same state exhibited nearly as much relative variation as within the nation as a whole. Monitoring the mortality burden at this level of geographic detail is critical for guiding precision public health responses.

HIV Epidemiology in Uganda: survey based on age, gender, number of sexual partners and frequency of testing

Background

Human Immunodeficiency Virus (HIV) is a major cause of morbidity and mortality in the world. When compared to the developed countries where HIV prevalence is on the decline, sub-Saharan Africa has experienced either a rise or stagnation in rates.

Objectives

The aim of this study was to test and educate the community in the villages of Masajja and Kibiri of Wakiso district in Uganda for HIV and safe sex practices.

Methods

A sociodemographic survey was also performed to obtain data for gender, age, number of sexual partners during the previous year, frequency of testing and if ever tested positive for other sexually transmitted diseases (STDs).

Results

While 7 of the tested individuals were positive for HIV, 77 reported that they had once tested positive for other STDs. Of the 7 HIV positive individuals, 4 were females and 3 males. Over half of the tested individuals reported only one sexual partner in past 12 months and more than a quarter were sexually active with more than one partner. Majority of our population also reported getting HIV tested every 6 months or less.

Conclusion

Robust implementation of methods such as education and frequent testing can lower Uganda's prevalence of HIV even further.

Immunological failure in HIV-infected adults from 2003 to 2015 in Southwest Ethiopia: a retrospective cohort study

OBJECTIVE

To assess the prevalence, trend and associated factors for immunological failure (IF), and the magnitude of antiretroviral therapy (ART) shift among adults infected with HIV in Southwest Ethiopia.

SETTING

A retrospective cohort study was undertaken using the data from ART clinic at Jimma University Teaching Hospital from 21 June 2003 to 15 March 2015.

PARTICIPANTS

Retrospective analysis of 4900 HIV-infected adult patient records dating from June 2003 to March 2015 was conducted.

PRIMARY OUTCOME MEASURE

The primary outcome was IF defined when cluster for differentiation 4 (CD4) count falls to the baseline (or below) or persistent CD4 levels below 100 cells/mm³ after 6 months of ART treatment. The analyses included descriptive and inferential statistics.

RESULTS

546 (19.5%) adults had developed clinical failure (CF), 775 (19.7%) adults had developed IF and 1231 (25.1%) had developed either CF or IF or both. The prevalence of IF was consistently high throughout the decade. Age 25 to ≤50 years adjusted OR (AOR 1.5, 9% CI 1.2 to 2.4), being female (AOR 1.8, 95% CI 1.3 to 1.9), late presenter for HIV care (AOR 2.2, 95% CI 1.6 to 2.7) and having baseline CD4 count below 200 cells/mm³ (AOR 5.5, 95% CI 4.1 to 7.4), and having no history of HIV testing before diagnosis (AOR 0.7, 95% CI 0.5 to 0.9) were the predictors for IF. Only 29 (0.9%) adults infected with HIV were shifted to second-line ART regimen.

CONCLUSIONS

The magnitude of CF or IF or both was found significant and consistently high throughout the calendar year although ART shift was found minimal. HIV-infected adult patients with IF were early age adults, females, late presenters for HIV care, and those who had low baseline CD4 counts and history of HIV testing before diagnosis.

Population-based outcome analysis of diffuse large B-cell lymphoma in people living with HIV infection and competent individuals

The prognostic factors and outcome of 58 acquired immunodeficiency syndrome-related diffuse large B-cell lymphoma (AR-DLBCL) patients from the Swiss HIV Cohort Study, diagnosed from 2004 to 2011, were compared with those of 326 immunocompetent (IC)-DLBCL from the Hematology Division of the Amedeo Avogadro University (Italy) and the Oncology Institute of Southern Switzerland. Median follow-up was 6 years; 5-year overall survival (OS) was 68% (95% CI: 63%-73%) in IC-DLBCL and 63% (95% CI: 49%-75%) in AR-DLBCL (P = .220). The acquired immunodeficiency syndrome-related lymphoma international prognostic index predicted OS in AR-DLBCL. Among 148 patients younger than 61 years (40 AR-DLBCL and 108 IC-DLBCL) treated with RCHOP/RCHOP-like regimens, 20 IC-DLBCL and 9 AR-DLBCL patients died and OS was not significantly different. A higher proportion of early deaths occurred in the AR-DLBCL: indeed, 1-year OS was 94% (95% CI: 87%-97%) in IC-DLBCL and 82% (95% CI: 66%-91%) in AR-DLBCL patients. After rituximab and active antiretroviral therapy introduction, AR-DLBCL and IC-DLBCL patients treated with curative intent have similar long-term survival.

Effectiveness of female condom in preventing HIV and sexually transmitted infections: a systematic review protocol

INTRODUCTION

The HIV pandemic continues to evolve with young women being the most vulnerable group to acquire infection. The presence of sexually transmitted infections (STIs) further enhances HIV susceptibility and also leads to long-term complications such as infertility and cervical cancer. The female condom is a self-initiated method for STI and HIV prevention but there are controversies on its effects. We aim to assess the effectiveness, safety and acceptability of the use of female condoms for prevention of STI and HIV acquisition among women.

METHODS AND ANALYSIS

We will search Cochrane Central Register of Controlled Trials, PubMed, EMBASE, Scopus, WHO International Clinical Trials Registry and reference lists of relevant publications for potentially eligible studies. We will screen search outputs, select eligible studies, extract data and assess risk of bias in duplicate; resolving discrepancies through discussion and consensus or arbitration. We will combine data from clinically homogenous studies in a fixed effect meta-analysis and assess the certainty of the evidence using the method for Grading of Recommendations Assessment, Development and Evaluation. We registered the planned systematic review with the International Prospective Register of Systematic Reviews (PROSPERO) in March 2018 and will finalise the search strategy in August 2018; conduct the searches and select eligible studies between August and October 2018; and collect data, conduct statistical analyses and prepare and submit the manuscript for consideration by a peer-reviewed journal between November 2018 and April 2019.

ETHICS AND DISSEMINATION

We will use publicly available data; hence no formal ethical approval is required for this review. We will disseminate the findings of this review through conference presentations and publication in an open-access peer-reviewed journal.

Unexpected synergistic HIV neutralization by a triple microbicide produced in rice endosperm

Our paper provides an approach for the durable deployment of anti-HIV agents in the developing world. We developed a transgenic rice line expressing three microbicidal proteins (the HIV-neutralizing antibody 2G12 and the lectins griffithsin and cyanovirin-N). Simultaneous expression in the same plant allows the crude seed extract to be used directly as a topical microbicide cocktail, avoiding the costs of multiple downstream processes. This groundbreaking strategy is realistically the only way that microbicidal cocktails can be manufactured at a cost low enough for the developing world, where HIV prophylaxis is most in demand.

The transmission of HIV can be prevented by the application of neutralizing monoclonal antibodies and lectins. Traditional recombinant protein manufacturing platforms lack sufficient capacity and are too expensive for developing countries, which suffer the greatest disease burden. Plants offer an inexpensive and scalable alternative manufacturing platform that can produce multiple components in a single plant, which is important because multiple components are required to avoid the rapid emergence of HIV-1 strains resistant to single microbicides. Furthermore, crude extracts can be used directly for prophylaxis to avoid the massive costs of downstream processing and purification. We investigated whether rice could simultaneously produce three functional HIV-neutralizing proteins (the monoclonal antibody 2G12, and the lectins griffithsin and cyanovirin-N). Preliminary in vitro tests showed that the cocktail of three proteins bound to gp120 and achieved HIV-1 neutralization. Remarkably, when we mixed the components with crude extracts of wild-type rice endosperm, we observed enhanced binding to gp120 in vitro and synergistic neutralization when all three components were present. Extracts of transgenic plants expressing all three proteins also showed enhanced in vitro binding to gp120 and synergistic HIV-1 neutralization. Fractionation of the rice extracts suggested that the enhanced gp120 binding was dependent on rice proteins, primarily the globulin fraction. Therefore, the production of HIV-1 microbicides in rice may not only reduce costs compared to traditional platforms but may also provide functional benefits in terms of microbicidal potency.

Lower-Income Countries That Face The Most Rapid Shift In Noncommunicable Disease Burden Are Also The Least Prepared

Demographic and epidemiological changes are shifting the disease burden from communicable to noncommunicable diseases in lower-income countries. Within a generation, the share of disease burden attributed to noncommunicable diseases in some poor countries will exceed 80 percent, rivaling that of rich countries, but this burden is likely to affect much younger people in poorer countries. The health systems of lower-income countries are unprepared for this change. We examined the shift to noncommunicable diseases and estimated preparedness for the shift by ranking 172 nations using a health system capacity index for noncommunicable disease. We project that the countries with the greatest increases in the share of disease burden attributable to noncommunicable disease over the next twenty-five years will also be the least prepared for the change, as they ranked low on our capacity index and are expected to have the smallest increases in national health spending. National governments and donors must invest more in preparing the health systems of lower-income countries for the dramatic shift to noncommunicable diseases and in reducing modifiable noncommunicable disease risks.

Viral glycoproteomes: technologies for characterization and outlook for vaccine design

It has long been known that surface proteins of most enveloped viruses are covered with glycans. It has furthermore been demonstrated that glycosylation is essential for propagation and immune evasion for many viruses. The recent development of high-resolution mass spectrometry techniques has enabled identification not only of the precise structures but also the positions of such post-translational modifications on viruses, revealing substantial differences in extent of glycosylation and glycan maturation for different classes of viruses. In-depth characterization of glycosylation and other post-translational modifications of viral envelope glycoproteins is essential for rational design of vaccines and antivirals. In this Review, we provide an overview of techniques used to address viral glycosylation and summarize information on glycosylation of enveloped viruses representing ongoing public health challenges. Furthermore, we discuss how knowledge on glycosylation can be translated to means to prevent and combat viral infections.

Trend of HIV/AIDS for the last 26 years and predicting achievement of the 90-90-90 HIV prevention targets by 2020 in Ethiopia: a time series analysis

BACKGROUND

HIV infection continues to be epidemic of public health importance with a prevalence of 1.1% and incidence of 0.33/1000 population having low-intensity mixed epidemic. Ethiopia has adopted the 90-90-90 by 2020 target but its progress was not yet assessed. Therefore, this study aimed to assess the trend of HIV infection for the last 26 years and to predict the achievements of the 90-90-90 target.

METHODS

We used aggregates of HIV/AIDS indicator data from 1990 to 2016 of UNAIDS data bases. The data were analyzed with excel and STATA. The trend line that best fits the regression was drawn, annual change was estimated and future values of HIV detection rate, coverage of antiretroviral therapy and viral suppression indicators were predicted and compared with the 90-90-90 targets.

RESULT

Since 1995, new infection has declined by 81% and since 2002; number of HIV cases has declined by 35.5%. However, after remarkable decline for decades, since 2008 HIV incidence rate began to rise by 10% and number of new infection diagnosed each year increased by 36% among all ages and doubled among adults. ART coverage has increased by 90% among all age and tripled among pregnant women within 6 years. Nationally, 67% of people living with HIV know their status, 88% of them are on treatment and 86% of people on treatment have viral suppression. As a result, AIDS-related death declined by 77 and 79% among all age and children respectively. By 2020, 79% of people living with HIV will know their HIV status, of which 96-99% of HIV infected people will be on ART and more than 86% will have viral suppression.

CONCLUSION

After remarkable decline, HIV infection started to increase in the last few years among adults. With the current trend, Ethiopia will achieve the second and third 90% HIV targets, while the first target is not achievable and without achieving this overarching goal control of the epidemic will not be achieved. Therefore due attention is needed to avert the current epidemics and diagnosis of cases.

Sustained progress, but no room for complacency: Results of 2015 HIV estimations in India

Background & objectives:

Evidence-based planning has been the cornerstone of India's response to HIV/AIDS. Here we describe the process, method and tools used for generating the 2015 HIV estimates and provide a summary of the main results.

Methods:

Spectrum software supported by the UNAIDS was used to produce HIV estimates for India as a whole and its States/Union Territories. This tool takes into consideration the size and HIV prevalence of defined population groups and programme data to estimate HIV prevalence, incidence and mortality over time as well as treatment needs.

Results:

India's national adult prevalence of HIV was 0.26 per cent in 2015. Of the 2.1 million people living with HIV/AIDS, the largest numbers were in Andhra Pradesh, Maharashtra and Karnataka. New HIV infections were an estimated 86,000 in 2015, reflecting a decline by around 32 per cent from 2007. The declining trend in incidence was mirrored in most States, though an increasing trend was detected in Assam, Chandigarh, Chhattisgarh, Gujarat, Sikkim, Tripura and Uttar Pradesh. AIDS-related deaths were estimated to be 67,600 in 2015, reflecting a 54 per cent decline from 2007. There were variations in the rate and trend of decline across India for this indicator also.

Interpretation & conclusions:

While key indicators measured through Spectrum modelling confirm success of the National AIDS Control Programme, there is no room for complacency as rising incidence trends in some geographical areas and population pockets remain the cause of concern. Progress achieved so far in responding to HIV/AIDS needs to be sustained to end the HIV epidemic.

Survival of HIV infected patients on maintenance hemodialysis in Cameroon: a comparative study

Background

There are conflicting reports on the impact of HIV in the era of combined antiretroviral (c-ART) on survival of patient with ESKD. We aimed to compare the one-year survival of HIV positive patients to that of their HIV negative counterparts with ESKD on maintenance haemodialysis in Cameroon.

Methods

This was a retrospective cohort study conducted in the haemodialysis units of the Douala and Yaoundé General Hospitals. All HIV positive patients treated by maintenance haemodialysis between January 2007 and March 2015 were included. A comparative group of HIV negative patients with ESKD were matched for age, sex, co morbidities, year of dialysis initiation and haemodialysis unit. Relevant data at the time of haemodialysis initiation and during the first year of haemodialysis was noted. Survival was analysed using the Kaplan Meier and Cox regression hazard ratio estimator. A p value < 0.05 was considered statistically significant.

Results

A total of 57 patients with HIV and 57 without HIV were included. Mean age was 46.25 ± 11.41 years, and 52.6% were females in both groups. HIV nephropathy (50.9%) was the main presumed aetiology of ESKD in the HIV group, while chronic glomerulonephritis (33.3%) and diabetes (21.1%) were the main aetiologies in the HIV negative group. At initiation of dialysis, the median CD4 count was 212 cell/mm³ (IQR; 138–455) and 77.2% were receiving c-ART. The proportion of patients who initiated dialysis with a temporary venous catheter was similar in both groups (p = 0.06). After one year on haemodialysis, survival rate was lower in the HIV positive group compared to the HIV negative group (61.4%/78.9%, HR: 2.05; 95% CI: 1.03–4.08; p = 0.042).Kaplan Meier survival curve was in direction of a lower survival in HIV positive group (p = 0.052).

Conclusion

The one year survival of HIV positive patients on maintenance haemodialysis in Cameroon seems to be lower compared to their HIV negative counterparts.

Performance of verbal autopsy methods in estimating HIV-associated mortality among adults in South Africa

INTRODUCTION

Verbal autopsy (VA) can be integrated into civil registration and vital statistics systems, but its accuracy in determining HIV-associated causes of death (CoD) is uncertain. We assessed the sensitivity and specificity of VA questions in determining HIV status and antiretroviral therapy (ART) initiation and compared HIV-associated mortality fractions assigned by different VA interpretation methods.

METHODS

Using the WHO 2012 instrument with added ART questions, VA was conducted for deaths among adults with known HIV status (356 HIV positive and 103 HIV negative) in South Africa. CoD were assigned using physician-certified VA (PCVA) and computer-coded VA (CCVA) methods and compared with documented HIV status.

RESULTS

The sensitivity of VA questions in detecting HIV status and ART initiation was 84.3% (95% CI 80 to 88) and 91.0% (95% CI 86 to 95); 283/356 (79.5%) HIV-positive individuals were assigned HIV-associated CoD by PCVA, 166 (46.6%) by InterVA-4.03, 201 (56.5%) by InterVA-5, and 80 (22.5%) and 289 (81.2%) by SmartVA-Analyze V.1.1.1 and V.1.2.1. Agreement between PCVA and older CCVA methods was poor (chance-corrected concordance [CCC] <0; cause-specific mortality fraction [CSMF] accuracy ≤56%) but better between PCVA and updated methods (CCC 0.21-0.75; CSMF accuracy 65%-98%). All methods were specific (specificity 87% to 96%) in assigning HIV-associated CoD.

CONCLUSION

All CCVA interpretation methods underestimated the HIV-associated mortality fraction compared with PCVA; InterVA-5 and SmartVA-Analyze V.1.2.1 performed better than earlier versions. Changes to VA methods and classification systems are needed to track progress towards targets for reducing HIV-associated mortality.

Early detection of peripheral neuropathy using stimulated skin wrinkling test in human immunodeficiency virus infected patients: A cross-sectional study

Peripheral neuropathy is a common condition of human immunodeficiency virus (HIV)-infected patients, which often remains undetected. We assessed the performance of stimulated skin wrinkling-eutectic mixture of local anesthetic (SSW-EMLA) test compared with brief peripheral neuropathy screening (BPNS) to detect HIV neuropathy.This is a cross-sectional study conducted in HIV-positive patients. A modified skin wrinkling grading was used to assess SSW-EMLA effect. BPNS-detectable neuropathy was assessed by a combination of neuropathy severity scoring scale (subjective) and objective method of sensory and tendon reflex examination. The SSW-EMLA test accuracy with reference to BPNS was assessed using sensitivity and specificity and predictive values.In a total of 99 HIV patients, 61.6% were males and the majority age group were between 30 and 40 years (52%). The neuropathy detection was SSW-EMLA test 36.4% versus BPNS 15.2% (P = .04). The sensitivity of SSW-EMLA test was 60.0% [95% confidence interval (95% CI) 34.5-81.7], specificity 67% (95% CI 63.3-3-71.7), and overall accuracy of 66.7% (95% CI 58.9-73.2).The SSW-EMLA test detected many more peripheral neuropathy cases than BPNS in HIV patients and has potential as an alternative test for screening for HIV neuropathy in resource-constraint hospitals in Indonesia.

Implementation and evaluation of a therapeutic patient education programme during a clinical trial in Yaoundé, Cameroon - Trial ANRS-12286/MOBIDIP

OBJECTIVES

High adherence is needed to maintain antiretroviral therapy efficacy. Few attempts at therapeutic patient education (TPE) have been made in sub-Saharan Africa. We describe patients' achievements before intervention and identified needs, TPE programme implementation and evaluation, and patients' satisfaction.

METHODS

The TPE programme was proposed to patients in the ANRS-12286/MOBIDIP trial. Beforehand, a directory of competences to manage HIV infection was designed. Patients' HIV-related knowledge and skills assessment was realised, leading to an educational contract. Evaluation was performed using a standardised collection form and a satisfaction survey.

RESULTS

Of 154 patients, 146 underwent TPE. During a median of 1.8 years, 47% of patients had ≥3 consultations. Educational assessment revealed limited knowledge about HIV disease. Conversely, patients had frequently managed issues of adherence or disclosure. A median of 12 objectives were considered per patient, and 75% were attained. Objectives from the cognitive domain were less frequently attained. Patients appeared satisfied with the intervention: more emphasis was placed on psycho-affective aspects or experience-sharing than on the acquisition of knowledge.

CONCLUSION

Active listening, know-how and a space for discussion appear more important for patients than knowledge on disease or treatments.

PRACTICE IMPLICATIONS

In HIV care, the directory of learning objectives should be revised to include more objectives concerning practical skills for disease management.

Investigating Organ Toxicity Profile of Tenofovir and Tenofovir Nanoparticle on the Liver and Kidney: Experimental Animal Study

Tenofovir nanoparticles are novel therapeutic intervention in human immunodeficiency virus (HIV) infection reaching the virus in their sanctuary sites. However, there has been no systemic toxicity testing of this formulation despite global concerns on the safety of nano drugs. Therefore, this study was designed to investigate the toxicity of Tenofovir nanoparticle (NTDF) on the liver and kidney using an animal model. Fifteen adult male Sprague-Dawley (SD) rats maintained at the animal house of the biomedical resources unit of the University of KwaZulu-Natal were weighed and divided into three groups. Control animals (A) were administered with normal saline (NS). The therapeutic doses of Tenofovir (TDF) and nanoparticles of Tenofovir (NTDF) were administered to group B and C and observed for signs of stress for four weeks after which animals were weighed and sacrificed. Liver and kidney were removed and fixed in formal saline, processed and stained using H/E, PAS and MT stains for light microscopy. Serum was obtained for renal function test (RFT) and liver function test (LFT). Cellular measurements and capturing were done using ImageJ and Leica software 2.0. Data were analysed using graph pad 6, p values < 0.05 were significant. We observed no signs of behavioural toxicity and no mortality during this study, however, in the kidneys, we reported mild morphological perturbations widening of Bowman's space, and vacuolations in glomerulus and tubules of TDF and NTDF animals. Also, there was a significant elevation of glycogen deposition in NTDF and TDF animals when compared with control. In the liver, there were mild histological changes with widening of sinusoidal spaces, vacuolations in hepatocytes and elevation of glycogen deposition in TDF and NTDF administered animals. In addition to this, there were no significant differences in stereological measurements and cell count, LFT, RFT, weight changes and organo-somatic index between treatment groups and control. In conclusion, NTDF and TDF in therapeutic doses can lead to mild hepatic and renal histological damage. Further studies are needed to understand the precise genetic mechanism.

Understanding willingness to use oral pre-exposure prophylaxis for HIV prevention among men who have sex with men in China

Background

Oral pre-exposure prophylaxis (PrEP) is recommended as an additional prevention choice for men who have sex with men (MSM) at substantial risk of HIV. The aim of this study was to evaluate the extent, and reasons, for MSM’s willingness to use oral PrEP in Wuhan and Shanghai, China.

Methods

Between May and December 2015, a cross-sectional survey was conducted among 487 MSM recruited through snowball sampling in physical locations frequented by MSM and through social media applications. Exploratory factor analysis was used to group reasons for being willing or not willing to use PrEP. Chi-square tests were used to explore bivariate associations between groupings of reasons for being willing or unwilling to use PrEP, and key sociodemographic and sexual-behavioral characteristics of MSM.

Results

Overall, 71.3% of respondents were willing to use PrEP. The most commonly reported reasons for being willing to use PrEP were preventing HIV infection (91.6%), taking responsibility for own sexual health (72.6%) and protecting family members from harm (59.4%). The main reasons for being unwilling to use PrEP were being worried about side effects (72.9%), the necessity of taking PrEP for long periods of time (54.3%) and cost (40.4%). Individual characteristics that influenced the type of reasons given for being willing or unwilling to use PrEP included being married to a woman, having a regular sex partner, rates of condom use with regular and casual sex partners, and the number of casual sex partners.

Conclusion

The introduction of PrEP in China could benefit from promotion campaigns that emphasize its role in preventing HIV infection, in taking responsibility for own sexual health, and in protecting family members from potential harm. To reduce uptake barriers, it will be essential to provide accurate information to potential PrEP users about the mild and short-term nature of side effects, and the possibility of taking PrEP only during particular periods of life when the risk of HIV exposure might be highest.

Early mortality among children and adults in antiretroviral therapy programs in Southwest Ethiopia, 2003-15

Background

Several studies reported that the majority of deaths in HIV-infected people are documented in their early antiretroviral therapy (ART) follow-ups. Early mortality refers to death of people on ART for follow up period of below 24 months due to any cause. The current study assessed predictors of early HIV mortality in Southwest Ethiopia.

Methods

We have conducted a retrospective analysis of 5299 patient records dating from June 2003- March 2015. To estimate survival time and compare the time to event among the different groups of patients, we used a Kaplan Meir curve and log-rank test. To identify mortality predictors, we used a cox regression analysis. We used SPSS-20 for all analyses.

Results

A total of 326 patients died in the 12 years follow-up period contributing to 6.2% cumulative incidence and 21.7 deaths per 1000 person-year observations incidence rate. Eighty-nine percent of the total deaths were documented in the first two years follow up—an early-term ART follow up. Early HIV mortality rates among adults were 50% less in separated, divorced or widowed patients compared with never married patients, 1.6 times higher in patients with baseline CD4 count <200 cells/μL compared to baseline CD4 count ≥200 cells/μL, 1.5 times higher in patients with baseline WHO clinical stage 3 or 4 compared to baseline WHO clinical stage 1 or 2, 2.1 times higher in patients with immunologic failure compared with no immunologic failure, 60% less in patients with fair or poor compared with good adherence, 2.9 times higher in patients with bedridden functional status compared to working functional status, and 2.7 times higher with patients who had no history of HIV testing before diagnosis compared to those who had history of HIV testing. Most predictors of early mortality remained the same to the predictors of an overall HIV mortality. When discontinuation was assumed as an event, the predictors of an overall HIV mortality included age between 25–50 years, base line CD4 count, developing immunologic failure, bedridden functional status, and no history of HIV testing before diagnosis.

Conclusions

The great majority of deaths were documented in the first two years of ART, and several predictors of early HIV mortality were also for the overall mortality when discontinuation was assumed as event or censored. Considering the above population, interventions to improve HIV program in the first two years of ART follow up should be improved.

Knowledge, attitudes and practices of health personnel of maternities in the prevention of mother-to-child transmission of HIV in a sub-Saharan African region with high transmission rate: some solutions proposed

Background

High mother-to-child (MTC) transmission rate of HIV might contribute to the increased pandemic rate. The aim of this study was to identify the knowledge, attitude and practices of health personnel working in maternities in the prevention of MTC transmission of HIV.

Methods

This cross-sectional descriptive study was carried out from 20th February to 30th April, 2017. All health personnel working in the maternity wards were included in this study. The variables recorded included their age, grade, experience (number of year of practice), gender, educational level, health structure and the training in prevention of MTC transmission of HIV. Analyses were done using SPSS 21.0. The Pearson Chi-square test or Fisher’s exact test and logistic regression were used for comparison. The level of significance was P < 0.05.

Results

A total of 140 health personnel were recruited. Knowledge was insufficient amongst 73 of them (52.1%). The factors significantly associated with sufficient knowledge were midwifery qualification (aOR 9.01, 95% CI 1.82–48.60) and training in prevention of MTC transmission of HIV (aOR 2.23, 95% CI 1.02–4.81). Regarding attitudes, it was negative in 85 practitioners (60.7%). Only those aged ≥33 years were significantly associated with a positive attitude (aOR 2.34, 95% CI 1.14–4.23). As concerns practices, only 32 practitioners (22.9%) had good practices. Only midwives were associated with good practices (aOR 3.23, 95% CI 1.21–9.95).

Conclusion

Insufficient knowledge, attitude and practices in the prevention of MTC transmission of HIV were observed among the majority of health personnel in the region. This lack of knowledge in prevention can therefore contribute to the rise of the mother-to-child transmission rate of HIV. To reduce this rate, more health personnel should be trained, especially midwives, in the prevention of MTC transmission of HIV. Moreover, deliveries of all women living with HIV should be conducted or at least supervised by trained midwives, especially those of at least 33 years of age.

Reasons and predictors for antiretroviral therapy change among HIV-infected adults at South West Ethiopia

OBJECTIVE

This retrospective cohort study is aimed to assess reasons and predictors of regimen change from initial highly active antiretroviral therapy among 1533 Human Immunodeficiency virus-infected adult patients at the Jimma University Tertiary Hospital.

RESULTS

One in two (47.7%) adults changed their antiretroviral therapy regimen. Patients who were above the primary level of education [Hazard ratio (HR) 1.241 (95% CI 1.070-1.440)] and with human immunodeficiency virus/tuberculosis co-infection [HR 1.405 (95% CI 1.156-1.708)] had the higher risk of regimen change than their comparator. Individuals on Efavirenz [HR 0.675 (95% CI 0.553-0.825)] and non-stavudine [HR 0.494 (95% CI 0.406-0.601)] based regimens had lower risk of regimen change.

Alcohol retail sales licenses and sexually transmitted infections in Texas counties, 2008-2015

BACKGROUND

Research suggests that reduced retail alcohol outlet density may be associated with lower prevalence of HIV and other sexually transmitted infections (STIs). On-premise sale of alcohol for immediate consumption is theorized as increasing social interactions that can lead to sexual encounters.

OBJECTIVE

We examined associations between on- and off-premise retail alcohol sales licenses and number of newly diagnosed HIV and STI cases in Texas counties.

METHODS

Retail alcohol sales license data were obtained from the Texas Alcoholic Beverage Commission. HIV and bacterial STI data were obtained from the Texas Department of State Health Services. Associations between retail alcohol sales licenses and STIs were estimated using spatial linear models and Poisson mixed effects models for over-dispersed count data.

RESULTS

Adjusting for county-specific confounders, there was no evidence of residual spatial correlation. In Poisson models, each additional on-premise (e.g., bar and restaurant) alcohol license per 10,000 population in a county was associated with a 1.5% increase (95% CI: 0.4%, 2.6%) in the rate of HIV and a 2.4% increase (95% CI: 1.9%, 3.0%) in the rate of bacterial STIs, adjusting for potential confounders. In contrast, number of off-premise licenses (e.g., take-out stores) was inversely associated with the incidence of STI and HIV, although the association with HIV was not statistically significant.

CONCLUSIONS

This study adds to the limited literature on the association between retail alcohol availability and STIs. Additional research is needed on the role of alcohol availability (and policies affecting availability) in the spread of HIV and other STIs.

Heterogeneity in geographical trends of HIV epidemics among key populations in Pakistan: a mathematical modeling study of survey data

BACKGROUND

Assessing patterns and trends in new infections is key to better understanding of HIV epidemics, and is best done through monitoring changes in incidence over time. In this study, we examined disparities in geographical trends of HIV epidemics among people who inject drugs (PWIDs), female sex workers (FSWs) and hijra/transgender/male sex workers (H/MSWs), in Pakistan.

METHODS

The UNAIDS Estimation and Projection Package (EPP) mathematical model was used to explore geographical trends in HIV epidemics. Four rounds of mapping and surveillance data collected among key populations (KPs) across 20 cities in Pakistan between 2005-2011 was used for modeling. Empirical estimates of HIV prevalence of each KP in each city were used to fit the model to estimate prevalence and incidence over time.

RESULTS

HIV incidence among PWIDs in Pakistan reached its peak in 2011, estimated at 45.3 per 1000 person-years. Incidence was projected to continue to rise from 18.9 in 2015 to 24.3 in 2020 among H/MSWs and from 3.2 in 2015 to 6.3 in 2020 among FSWs. The number of people living with HIV in Pakistan was estimated to steadily increase through at least 2020. HIV incidence peak among PWIDs ranged from 16.2 in 1997 in Quetta to 71.0 in 2010 in Faisalabad (per 1000 person-years). Incidence among H/MSWs may continue to rise through 2020 in all the cities, except in Larkana where it peaked in the early 2000s. In 2015, model estimated incidence among FSWs was 8.1 in Karachi, 6.6 in Larkana, 2.0 in Sukkur and 1.2 in Lahore (per 1000 person-years).

CONCLUSIONS

There exists significant geographical heterogeneity in patterns and trends of HIV sub-epidemics in Pakistan. Focused interventions and service delivery approaches, different by KP and city, are recommended.

AIDS Clinical Research in Spain-Large HIV Population, Geniality of Doctors, and Missing Opportunities

The first cases of AIDS in Spain were reported in 1982. Since then over 85,000 persons with AIDS have been cumulated, with 60,000 deaths. Current estimates for people living with HIV are of 145,000, of whom 20% are unaware of it. This explains the still high rate of late HIV presenters. Although the HIV epidemic in Spain was originally driven mostly by injection drug users, since the year 2000 men having sex with men (MSM) account for most new incident HIV cases. Currently, MSM represent over 80% of new yearly HIV diagnoses. In the 80s, a subset of young doctors and nurses working at Internal Medicine hospital wards became deeply engaged in attending HIV-infected persons. Before the introduction of antiretrovirals in the earlier 1990s, diagnosis and treatment of opportunistic infections was their major task. A new wave of infectious diseases specialists was born. Following the wide introduction of triple combination therapy in the late 1990s, drug side effects and antiretroviral resistance led to built a core of highly devoted HIV specialists across the country. Since then, HIV medicine has improved and currently is largely conducted by multidisciplinary teams of health care providers working at hospital-based outclinics, where HIV-positive persons are generally seen every six months. Antiretroviral therapy is currently prescribed to roughly 75,000 persons, almost all attended at clinics belonging to the government health public system. Overall, the impact of HIV/AIDS publications by Spanish teams is the third most important in Europe. HIV research in Spain has classically been funded mostly by national and European public agencies along with pharma companies. Chronologically, some of the major contributions of Spanish HIV research are being in the field of tuberculosis, toxoplasmosis, leishmaniasis, HIV variants including HIV-2, drug resistance, pharmacology, antiretroviral drug-related toxicities, coinfection with viral hepatitis, design and participation in clinical trials with antiretrovirals, immunopathogenesis, ageing, and vaccine development.

Sexual Risk Behaviors of Patients with HIV/AIDS over the Course of Antiretroviral Treatment in Northern Vietnam

Antiretroviral therapy (ART) improves the health and well-being of people living with the human immunodeficiency virus (HIV, PLWH), and reduces their risk of transmitting the virus to sexual partners. However, patterns of sexual risk behavior among HIV-positive patients taking ART in Vietnam remain largely unknown. In this study, we sought to examine sexual risk behaviors and their associated factors among HIV-positive patients receiving ART in northern Vietnam. The socio-demographic characteristics, ART use, health status, and sexual behaviors of 1133 patients taking ART in the Hanoi and Nam Dinh provinces were explored through face-to-face interviews. There were 63.5% of patients who had one sex partner, while 3.6% and 5.6% of patients had sexual intercourse with casual partners or sex workers, respectively, in the previous 12 months. Most participants tended to use condoms more often with commercial sex partners (90.2%) and intimate partners (79.7%), and less often with casual partners (60.9%). Higher age (odds ratio, OR = 1.0; 95% CIs = 1.0, 1.1) or suffering pain/discomfort (OR = 1.7; 95% CIs = 1.2, 2.4) were factors more likely to be associated with multiple sex partners. Patients who were self-employed were more likely to have sexual intercourse with casual partners/sex workers (OR = 2.1; 95% CIs = 1.1, 4.0). Meanwhile, a higher score on the EuroQol visual analog scale (EQ-VAS), an unknown HIV stage, and a longer duration of ART were adversely associated with not using condoms with casual partners/sex workers. Patients with longer durations of ART had a lower likelihood of not using a condom with casual partners/sex workers (OR = 0.5; 95% CIs = 0.3, 0.8). Our study underscored a relatively high rate of unsafe sexual behaviors among HIV-positive patients. Continuing to improve the physical and psychological well-being of HIV-positive patients in Vietnam is important in reducing the spread of HIV via risky sexual behaviors. In addition, safe-sex education should be provided to older people, and to those who are self-employed.

Epidemiological, clinical and laboratory aspects of human visceral leishmaniasis (HVL) associated with human immunodeficiency virus (HIV) coinfection: a systematic review

Coinfection with human visceral leishmaniasis (HVL) and human immunodeficiency virus (HIV) has become an emerging public health problem in several parts of the world, with high morbidity and mortality rates. A systematic review was carried out in the literature available in PubMed, Scielo and Lilacs related to HVL associated with HIV coinfection, seeking to analyze epidemiological, clinical and laboratory aspects. Of the 265 articles found, 15 articles were included in the qualitative analysis, which referred to the results of HVL treatment in patients coinfected with HIV. In the published articles between 2007 and 2015, 1171 cases of HVL/HIV coinfection were identified, 86% males, average age 34 years, liposomal amphotericin B was the most commonly used drug, cure rates 68 and 20% relapses and 19% deaths, five different countries, bone marrow was used in 10/15 manuscripts. HVL/HIV coinfection is a major challenge for public health, mainly due to the difficulty in establishing an accurate diagnosis, low response to treatment with high relapse rates and evolution to death. In addition, these two pathogens act concomitantly for the depletion of the immune system, contributing to worsening the clinical picture of these diseases, which requires effective surveillance and epidemiological control measures.

The diagnosis of symptomatic acute antiretroviral syndrome during the window period with antigen/antibody testing and HIV viral load

Despite much focus on moving toward a cure to end the epidemic human immunodeficiency virus (HIV) epidemic there are still thousands of new infections occurring every year in the United States. Although there is ongoing transmission of HIV in the United States and a growing population of people living with HIV, the acute presentation of HIV infection can be challenging to diagnose and is often not considered when patients present to healthcare providers. Although in certain states there are HIV testing laws that require that all persons between the ages of 13 and 64 be offered HIV testing in an opt-out approach, many patient presenting with an acute illness, that would warrant diagnostic testing for HIV, leave without having an HIV test performed for either diagnostic or screening purposes. We describe the case of a woman who presented to medical attention with symptoms later confirmed to be due to acute HIV infection. She was initially discharged from the hospital and only underwent HIV testing with confirmation of her diagnosis after readmission. We describe the algorithm where fourth generation testing combined with HIV viral load testing allowed for the diagnosis of acute HIV prior to the development of a specific immunoglobulin response. Consideration of this diagnosis, improved HIV screening, and understanding of the use of antigen/antibody screening tests, combined with Multispot and HIV viral RNA detection, when appropriate, can allow for early diagnosis of HIV before progression of disease and before undiagnosed patient spread the infection to new contacts.

HIV/AIDS Mortality in Brazil, 2000-2015: Are there reasons for concern?

Introduction and objective:

Mortality studies are essential for the monitoring of the HIV/AIDS epidemic. Quality and completeness of data from the mortality information system (SIM) require complementary approaches.

Methods:

Two sources of data were used to assess mortality trends due to HIV/AIDS in Brazil from 2000 and 2014/15: a) data from the SIM published by the Department of STDs, AIDS, and viral hepatitis, and b) Global Burden of Disease 2015 (GBD 2015) studies. Descriptive analyses were carried out and trends in relative reduction of age-adjusted mortality rates per 100,000 inhabitants were compared according to the two methods.

Results:

Overall, the magnitude of the mortality rates estimated by the GBD method, for Brazil and its Federative Units (FU), was greater than those obtained from the SIM. The relative reduction was higher for SIM data and there were shifts in the ranking according to the FUs. Between 2000 and 2014/15 there was an increase in the mortality rates for most of the FUs (78 and 88% according to the SIM and GBD, respectively).

Conclusion:

Data regarding mortality due to HIV/AIDS in Brazil should be of concern, regardless of the method used. Differences in magnitude, relative reductions, and ranking can be attributed to methodological differences, but the GBD is broader, with a higher capacity to capture incorrectly classified data and causes of death not registered or not coded as being due to HIV/AIDS. Alternative and complementary data sources can provide important information for HIV/AIDS public policies in Brazil.

Sequential immunizations with a panel of HIV-1 Env virus-like particles coach immune system to make broadly neutralizing antibodies

Broadly neutralizing antibodies (bnAbs) are correlated with passive HIV/SHIV protection and are desirable components of a HIV protective immunity. In the current study, we have designed a sequential-immunization strategy with a panel of envelope glycoprotein (Env)-enriched virus-like particles (VLPs) from various HIV-1 clades (A-E) to elicit bnAbs with high breadth and potency of neutralization in rabbits. We have compared this regimen with repetitive immunizations of individual Env (subtype B) VLPs or a mixture of various Env VLPs. Our results demonstrate that the sequential immunization group of animals induced significantly higher IgG endpoint titers against respective HIV Env (autologous) antigen than other control groups. Animals vaccinated sequentially showed an increase in the antibody endpoint titers and IgG antibody secreting cells (ASCs) against Con-S Env protein. Sequential immunizations with various Env VLPs promoted antibody avidity indices and enhanced bnAb responses against a panel of HIV pseudotyped virions including some of the tier 3 pseudostrains. Sequential immunizations with various VLPs displaying "native-like" HIV-1 Envs elicited bnAb responses with increased breadth and potency of neutralization.

HBV polymerase-derived peptide exerts an anti-HIV-1 effect by inhibiting the acetylation of viral integrase

Here, we found that a 6-mer peptide, Poly6, derived from the hepatitis B virus (HBV), which overlaps with a polymerase corresponding to a preS1 deletion reported to contribute to liver disease progression, can elicit an antiviral effect against human immunodeficiency virus (HIV)-1 by inhibiting HIV-1 integrase (IN) activity of infected cells. Mechanistic studies revealed that the anti-HIV-1 effects of Poly6 occurred via the inhibition of integration, which resulted from the inhibition of acetylation of HIV-1 IN possibly by downregulation of p300 histone acetyltransferase. Our data suggest the potential therapeutic use of a 6-mer HBV-derived peptide, Poly6, as an anti-HIV-1 agent to suppress HIV-1 infection via inhibiting integrase activity.

Securitizing HIV/AIDS: a game changer in state-societal relations in China?

BACKGROUND

China has experienced unprecedented economic growth since the 1980s. Despite this impressive economic development, this growth exists side by side with the human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) and severe acute respiratory syndrome (SARS) crises and the persisting deficiencies in public health provision in China. Acknowledging the prevailing health problems, the Chinese government has encouraged the development of health non-governmental organizations (NGOs) to respond to the health challenges and address the gaps in public health provision of the government. HIV/AIDS-focused NGOs have been perceived as the most outstanding civil society group developed in China. Considering the low priority of health policies since the economic reform, the limitation of the "third sector" activity permitted in authoritarian China, together with the political sensitivity of the HIV/AIDS problem in the country, this article aims to explain the proliferation of HIV/AIDS-focused NGOs in China with the usage of the securitization framework in the field of international relations (IR).

METHODS

The research that underpins this article is based on a desk-based literature review as well as in-depth field interviews with individuals working in HIV/AIDS-focused NGOs in China. Face-to-face interviews for this research were conducted between January and May in 2011, and between December 2016 and January 2017, in China. Discourse analysis was in particular employed in the study of the security-threat framing process (securitization) of HIV/AIDS in China.

RESULTS

This article argues that the proliferation of HIV/AIDS-related NGOs in China is largely attributed to the normative and technical effects of HIV/AIDS securitization ushered in by the United Nations Security Council (UNSC) and supported by the Global Fund to Fight AIDS, Tuberculosis, and Malaria (hereinafter Global Fund) observed in China. Despite depicting a positive scenario, the development of HIV/AIDS-focused NGOs in China generated by the international securitization efforts is largely limited. An internal and external factor was identified to verify the argument, namely (1) the reduction of international financial commitments, as well as (2) the fragmentation of HIV/AIDS-focused NGO community in China.

CONCLUSIONS

This article shows that international securitization weakened with the rise of Chinese commitment on HIV/AIDS interventions. In other words, HIV/AIDS-related responses delivered by the national government are no longer checked by the global mechanism of HIV/AIDS; thus it is unclear whether these NGOs would remain of interest as partners for the government. The fragmentation of the HIV/AIDS community would further hinder the development, preventing from NGOs with the same interest forming alliances to call for changes in current political environment. Such restriction on the concerted efforts of HIV/AIDS-related NGOs in China would make achievement of the Sustainable Development Goals (SDGs) to foster stronger partnerships between the government and civil society difficult, which in turn hindering the realization of ending HIV/AIDS in the world by 2030.

Efficacy of single-tablet darunavir, cobicistat, emtricitabine, and tenofovir alafenamide in the treatment of HIV-1

INTRODUCTION

HIV eradication is not feasible and lifelong treatment is warranted to manage HIV infection. In this scenario, the advent of single-tablet, once-daily, fixed-dose co-formulations is important for reducing pill burden and maximize long-term drug adherence. Cobicistat-boosted darunavir along with emtricitabine and tenofovir alafenamide co-formulation (DRV/c/FTC/TAF or the trade name Symtuza®) is the first marketed protease inhibitor-based fixed-dose combination regimen for the treatment of HIV infection. It was approved in late 2017 by the European Medical Agency both for naïve patients and treatment-experienced patients with viral suppression. Areas covered: PubMed, ClinicalTrials.gov and presentations at scientific meetings were searched with the terms 'darunavir/cobicistat' and 'tenofovir alafenamide and emtricitabine' for clinical trials either conducted to date or ongoing as well as a review of abstracts from major HIV/AIDS and infectious diseases conferences from 2015 to up to date. Expert opinion: DRV/c/FTC/TAF is a novel unique antiretroviral drug co-formulation that exhibits a convenient dosing, satisfactory safety profile, and high antiviral efficacy, even in patients harboring viruses with resistance to antivirals other than darunavir in the short-midterm. It represents the first fixed-dose combination therapy including a protease inhibitor given as one single pill once daily for drug-naïve patients and as second-line antiretroviral therapy.

HIV glycoprotein gp120 enhances mesenchymal stem cell migration by upregulating CXCR4 expression

BACKGROUND

HIV infection and/or the direct pathogenic effects of circulating HIV proteins impairs the physiological function of mesenchymal stem cells (MSCs), and contribute to the pathogenesis of age-related clinical comorbidities in people living with HIV. The SDF-1/CXCR4 pathway is vital for modulating MSC proliferation, migration and differentiation. HIV glycoprotein gp120 inhibits SDF-1 induced chemotaxis by downregulating the expression and function of CXCR4 in monocytes, B and T cells. The influence of gp120 on CXCR4 expression and migration in MSCs is unknown.

METHODS

We investigated CXCR4 expression and SDF-1/CXCR4-mediated MSC migration in response to gp120, and its effect on downstream signaling pathways: focal adhesion kinase (FAK)/Paxillin and extracellular signal-regulated kinase (ERK).

RESULTS

Gp120 upregulated MSC CXCR4 expression. This potentiated the effects of SDF-1 in inducing chemotaxis; FAK/Paxillin and ERK pathways were over-activated, thereby facilitating actin stress fiber reorganization. CXCR4 blockage or depletion abrogated the observed effects.

CONCLUSION

Gp120 from both T- and M- tropic HIV strains upregulated CXCR4 expression in MSCs, resulting in enhanced MSC chemotaxis in response to SDF-1.

GENERAL SIGNIFICANCE

HIV infection and its proteins are known to disrupt physiological differentiation of MSC; increased gp120-driven migration amplifies the total MSC population destined for ineffective and inappropriate differentiation, thus contributing to the pathogenesis of HIV-related comorbidities. Additionally, given that MSCs are permissive to HIV infection, initial cellular priming by gp120 results in increased expression of CXCR4 and could lead to co-receptor switching and cell tropism changes in chronic HIV infection and may have implications against CCR5-knockout based HIV cure strategies.

Trends in HIV/AIDS morbidity and mortality in Eastern Mediterranean countries, 1990-2015: findings from the Global Burden of Disease 2015 study

OBJECTIVES

We used the results of the Global Burden of Disease 2015 study to estimate trends of HIV/AIDS burden in Eastern Mediterranean Region (EMR) countries between 1990 and 2015.

METHODS

Tailored estimation methods were used to produce final estimates of mortality. Years of life lost (YLLs) were calculated by multiplying the mortality rate by population by age-specific life expectancy. Years lived with disability (YLDs) were computed as the prevalence of a sequela multiplied by its disability weight.

RESULTS

In 2015, the rate of HIV/AIDS deaths in the EMR was 1.8 (1.4-2.5) per 100,000 population, a 43% increase from 1990 (0.3; 0.2-0.8). Consequently, the rate of YLLs due to HIV/AIDS increased from 15.3 (7.6-36.2) per 100,000 in 1990 to 81.9 (65.3-114.4) in 2015. The rate of YLDs increased from 1.3 (0.6-3.1) in 1990 to 4.4 (2.7-6.6) in 2015.

CONCLUSIONS

HIV/AIDS morbidity and mortality increased in the EMR since 1990. To reverse this trend and achieve epidemic control, EMR countries should strengthen HIV surveillance, and scale up HIV antiretroviral therapy and comprehensive prevention services.
