In serodiscordant couples, provision of antiretroviral therapy (ART) to the HIV-infected partner significantly decreases risk of sexual HIV transmission of HIV. The World Health Organization has recently issued guidelines recommending ART initiation, regardless of CD4 count, for HIV-infected members of serodiscordant couples to prevent HIV transmission to the uninfected partner. We conducted a prospective cohort study among 1998 HIV-infected individuals with known HIV-uninfected partners who were enrolled in the Partners PrEP Study, an HIV prevention clinical trial in Kenya and Uganda. The primary objective was to assess ART initiation in those who became ART-eligible during study follow-up. The cumulative probabilities of initiating ART at 6, 12, and 24 months after referral were 60.8%, 78.8% and 91.5%, respectively. Approximately 40% of HIV-infected partners had not initiated ART six months after initial referrals. Higher CD4 (p0.001), asymptomatic HIV disease (p=0.04), and alcohol use (p=0.001) were significant predictors of ART initiation. To evaluate whether HIV-infected persons would be interested in earlier ART (CD4 350 cells/ [mu] L) for HIV prevention, as recommended by the WHO, we conducted a cross-sectional study among an additional 571 East African HIV-infected individuals in serodiscordant partnerships. The objective of the study was to determine whether fertility intentions were correlated with a greater likelihood to initiate early ART for prevention. We found that HIV-infected partners with fertility intentions were nearly twice as likely to express interest in early ART for HIV prevention (adjusted odds ratio [AHR] 1.83, p=0.02) than those without fertility intentions.

The introduction of antiretroviral therapy (ART) in middle and low income countries is arguably one of the most meaningful outcomes recorded in the fight against HIV and AIDS. A record number of some 6.2 million people living with HIV and AIDS are reported to be benefiting from the treatment, which is reported to have risen by 19 per cent between 2010 and 2011 and as a result of this, the region has also enjoyed a significant decline in AIDS mortality. This volume is the outcome of the call for abstracts put out by OSSREA in 2011 for senior researchers, social scientists and practitioners to write scientific articles on issues surrounding ARVs. The volume contains eight chapters organized into four sections: ART and quality of life; Adherence to ART; Traditional medicine and ART; and Sexual behaviour of ART attendants. The chapters are contributed by Academics and researchers from three different African countries: four from Ethiopia, two from Uganda and two from Zimbabwe.

Histoplasmosis is a disease caused by the fungus Histoplasma capsulatum. This disease is highly endemic in some regions of North America, Central America, and South America and is also reported in certain countries of Asia and Africa. It often affects people with impaired immunity, including people living with HIV, among whom the most frequent clinical presentation is disseminated histoplasmosis. The symptoms of disseminated histoplasmosis are non-specific and may be indistinguishable from those of other infectious diseases, especially disseminated tuberculosis (TB), thus complicating diagnosis and treatment. Histoplasmosis is one of the most frequent opportunistic infections caused by fungal pathogens among people living with HIV in the Americas and may be responsible for 5-15% of AIDS-related deaths every year in this Region. These guidelines aim to provide recommendations for the diagnosis, treatment, and management of disseminated histoplasmosis in persons living with HIV. Although the burden of disease is concentrated in the Americas, the recommendations presented within these guidelines are applicable globally. These guidelines were produced in accordance with the World Health Organization (WHO) handbook for guideline development. The Guideline Development Group elaborated the final recommendations based on a systematic review of scientific literature and critical evaluation of the evidence available using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach. These guidelines are intended for health-care providers, HIV program managers, policy-makers, national treatment advisory boards, researchers, and other professionals involved in caring for people who either have or may be at risk of developing disseminated histoplasmosis.

The studies described in this dissertation examine the relationship between use of antiretroviral therapy (ART) and biologic and behavioral factors related to HIV-1 transmission risk in stable heterosexual HIV-1 serodiscordant African couples. ART is recommended for all HIV-1 infected persons, regardless of CD4 count, to reduce HIV-1 related morbidity, mortality and risk of transmission to uninfected partners. ART is a cornerstone of combination HIV-1 prevention, and optimizing use of ART, both for treatment and prevention, is an urgent public health priority. The complementary prospective studies presented in this dissertation were secondary analyses of data from the Partners PrEP Study, a randomized clinical trial of daily oral pre-exposure prophylaxis (PrEP) to decrease HIV-1 acquisition among HIV-1 uninfected members of serodiscordant couples in Kenya and Uganda. This work includes prospective studies of: 1) correlates of failure to achieve plasma viral suppression and virologic rebound after initial suppression, 2) frequency, magnitude and correlates of seminal HIV-1 RNA shedding in men initiating ART, 3) residual HIV-1 transmission risk during the first 6 months of ART, and 4) sexual risk behavior before and after ART. Younger age was associated with delayed ART initiation, failure to achieve viral suppression, and increased risk of virologic rebound after initial suppression. Seminal HIV-1 RNA shedding was infrequent and present at low levels in HIV-1 infected African men with suppressed blood HIV-1 RNA. There were no HIV-1 transmission events on suppressive ART. We observed residual HIV-1 transmission risk during the first 6-months of ART, prior to complete viral suppression in blood and genital secretions. Importantly, substantial risk compensation did not occur following ART initiation among HIV-1 infected persons with known uninfected partners. Results from this dissertation contribute further evidence of the effectiveness of ART for HIV-1 prevention, and provide reassurance that HIV-1 transmission risk declines after starting ART. As treatment guidelines evolve from wait-and-treat to test-and-treat, scaling up access to HIV-1 testing, improving linkage and retention in care, and achieving high ART coverage and complete viral suppression at individual and population levels are essential to achieving zero new HIV-1 infections and zero AIDS-related deaths.

This report looks at what is being done to challenge the snail's pace of progress on access to antiretroviral medicines in three very different African countries: Botswana, South Africa and Uganda. It describes who is driving these initiatives at grassroots level and how. It offers insights and draws on lessons from firsthand experiences that can help those already working towards better access to antiretrovirals, and encourages others to embark on similar initiatives. It is intended for all those with an interest in this issue from policy- and decision-makers with the power to create a favourable environment for antiretroviral treatment, to those working on the front line in health services, NGOs and AIDS service organizations, as well as those living with HIV, whose role in the battle for wider access is so vital.

This dissertation informs the future implementation of HIV prevention for HIV serodiscordant couples in Africa. The research objectives include: 1) reviewing effective HIV prevention interventions, 2) evaluating the use of daily short message service (SMS, i.e. text message) surveys to measure sex and pre-exposure prophylaxis (PrEP) adherence, and 3) examining the acceptability of initiation of antiretroviral therapy (ART) at higher CD4 counts, a powerful HIV prevention tool. After the necessary first step of HIV testing and counseling, HIV serodiscordant couples may be offered appropriate HIV prevention interventions, including condoms, male circumcision, treatment of sexually transmitted infections, and two recent biomedical strategies: initiation of ART by the HIV-infected partner and PrEP by the HIV-uninfected partner. Importantly, the widespread implementation and effectiveness of HIV prevention interventions requires understanding and encouraging behaviors for acceptance, adherence, and correct use. We conducted a prospective study of HIV-related behaviors and qualitative research to answer key implementation questions regarding the feasibility of PrEP and acceptability of early ART among HIV serodiscordant couples. Within a clinical trial of PrEP, we evaluated the use of daily SMS surveys to examine patterns in sexual behavior and PrEP use. Daily SMS data collection was acceptable, obtained high response rates, and provided an assessment of temporal patterns of HIV risk behaviors and PrEP use over a 60-day period. Participants were more likely to adhere to daily PrEP doses when they were sexually-active, PrEP use was not associated with unprotected sex, and anticipating sex was difficult. In addition, HIV risk behaviors were reported on more days through daily SMS surveys compared to monthly interviewer-administered questionnaires, highlighting the potential of SMS to collect more accurate self-reported data. SMS may offer a new method for measuring and promoting behaviors related to HIV risk and adherence as well as enhancing communication between patients and providers. Qualitative research with HIV serodiscordant couples familiar with HIV prevention methodologies highlighted common perceived advantages and concerns related to early initiation of ART, and an important conceptualization of ART as the "final stage" before dying. This negative meaning of ART initiation poses a challenge to acceptance of early ART and indicates that new messages regarding ART initiation are needed. These new messages should emphasize the benefits of HIV prevention and maintaining good health; acknowledge concerns such as side effects and life-long adherence; and ultimately, portray a positive image of individuals on ART. Social and behavioral factors, in particular sustained adherence as well as individual and community acceptance, will be fundamental to successful implementation of early ART and PrEP and should remain a focus of HIV prevention and treatment
