    (The Lancet Global Health, 2013) Wanyenze, Rhoda K.; Kamya, Moses R.; Fatch, Robin; Mayanja-Kizza, Harriet; Baveewo, Steven; Szekeres, Gregory; Bangsberg, David; Coates, Thomas; Hahn, Judith A.
    HIV counselling and testing and linkage to care are crucial for successful HIV prevention and treatment. Abbreviated counselling could save time; however, its eff ect on HIV risk is uncertain and methods to improve linkage to care have not been studied. We did this factorial randomised controlled study at Mulago Hospital, Uganda. Participants were randomly assigned to abbreviated or traditional HIV counselling and testing; HIV-infected patients were randomly assigned to enhanced linkage to care or standard linkage to care. All study personnel except counsellors and the data offi cer were masked to study group assignment. Participants had structured interviews, given once every 3 months. We compared sexual risk behaviour by counselling strategy with a 6·5% non-inferiority margin. We used Cox proportional hazards analyses to compare HIV outcomes by linkage to care over 1 year and tested for interaction by sex. This trial is registered with ClinicalTrials.gov (NCT00648232). We enrolled 3415 participants; 1707 assigned to abbreviated counselling versus 1708 assigned to traditional. Unprotected sex with an HIV discordant or status unknown partner was similar in each group (232/823 [27·9%] vs 251/890 [28·2%], diff erence –0·3%, one-sided 95% CI 3·2). Loss to follow-up was lower for traditional counselling than for abbreviated counselling (adjusted hazard ratio [HR] 0·61, 95% CI 0·44–0·83). 1003 HIV-positive participants were assigned to enhanced linkage (n=504) or standard linkage to care (n=499). Linkage to care did not have a signifi cant eff ect on mortality or receipt of co-trimoxazole. Time to treatment in men with CD4 cell counts of 250 cells per μL or fewer was lower for enhanced linkage versus standard linkage (adjusted HR 0·60, 95% CI 0·41–0·87) and time to HIV care was decreased among women (0·80, 0·66–0·96).

    Antiretroviral Therapy and Sexual Behavior: A Comparative Study between Antiretroviral- Naive and -Experienced Patients at an Urban HIV/AIDS Care and Research Center in Kampala, Uganda
    (AIDS Patient Care & STDs, 2005) Bateganya, Moses; Colfax, Grant; Shafer, Leigh Anne; Kityo, Cissy; Mugyenyi, Peter; Serwadda, David; Mayanja, Harriet; Bangsberg, David
    We examined whether use of antiretroviral (ARV) therapy is associated with increased sexual risk behavior in a cross-sectional study of patients undergoing ARV therapy (ARV experienced) compared to patients not undergoing ARV therapy (ARV-naïve) attending an urban HIV clinic in Kampala, Uganda. Sexual behavior during the prior 6 months and sexually transmitted disease (STD) treatment was determined by face-to-face structured interviews. Multiple logistic regression was used to identify independent correlates of sexual activity, multiple sexual partners, inconsistent condom use, and STD treatment during the prior 6 months. Three hundred forty-seven (48%) of the 723 respondents reported a history of sexual intercourse in the 6 months prior to the interview (sexually active). Receipt of ARV therapy was not associated with a significantly higher likelihood of being sexually active (adjusted odds ratio [AOR], 2.0 95% confidence interval [CI], 0.3–9.9). Among both ARV-experienced and ARV-naïve persons who were sexually active, 35% (120) reported one or more casual sexual partners in addition to a main partner (no difference by ARV status). Consistent condom use with spouse, regular, casual, and commercial partners was reported by 57%, 65%, 85%, and 85% of the sexually active respondents, respectively. The ARV-experienced respondents were more likely to report consistent condom use with their spouses than were ARV-naïve respondents (OR 2.8295% CI 1.74–4.6). ARV-experienced respondents were more likely than ARV-naïve respondents to have disclosed their HIV status to their spouses (OR 1.57 95% CI 1.07–2.30).The ARV-experienced group was more likely to report STD treatment in the prior 6 months (AOR 2.62 95% CI 1.83.83) than the ARV-naïve group. The findings suggest that in this population, use of ARV therapy was not associated with risky sexual behavior in the prior 6 months. Still, recall and social desirability biases remain important limitations in interpreting these conclusions.

    Depression and All-Cause Mortality in an HIV Treatment Cohort in Rural Uganda!
    (U.S. National Institutes of Health, 2005) Tsai, Alexander; Chan, Brian; Yap, Boum; Jessica, Haberer; Kembabazi, Annet; Mocello, A. Rain; Hunt, Peter; Martin, Jeffrey; Bangsberg, David
    To determine the extent to which depression is associated with mortality among persons living with HIV (PLHIV) initiating antiretroviral therapy (ART).! 694 treatment-naïve PLHIV in rural Uganda were followed from initiation of ART. Each participant provided quarterly data through blood draws and structured interviews. Baseline depression symptom severity and mental health status were measured using locally adapted versions of the Hopkins Symptom Checklist and MOS-HIV mental health summary. Vital status was ascertained through participant tracing after missed study visits. We fit Cox proportional hazards regression models, adjusting our estimates for baseline age, sex, marital status, educational attainment, household asset wealth, CD4+ T-lymphocyte cell count, body mass index, and MOS-HIV physical health summary.! Over 4.3 median years of follow-up, only 48 participants (7%) were lost to follow-up and there were 44 deaths. After multivariable adjustment, probable depression was associated with increased mortality (AHR=2.24; 95% CI, 1.08-4.62), while mental health-related quality of life was not (AHR=0.98; 95% CI, 0.94-1.03).! Conclusions: Depressed mood is associated with increased mortality among HIV+ persons initiating ART. Screening for depression may be a relatively low-cost method of identifying HIV+ persons at high risk for mortality. Whether pre-ART depression reflects underlying immune activation or poor overall health status should be addressed in future studies.!

    Inhaled Nitric Oxide as an Adjunctive Treatment for Cerebral Malaria in Children: A Phase II Randomized Open-Label Clinical Trial
    (Oxford University Press, 2015) Mwanga-Amumpaire, Juliet; Carroll, Ryan W.; Baudin, Elisabeth; Kemigisha, Elisabeth; Nampijja, Dorah; Mworozi, Kenneth; Santorino, Data; Nyehangane, Dan; Nathan, Daniel I.; De Beaudrap, Pierre; Etard, Jean-François; Feelisch, Martin; Fernandez, Bernadette O.; Berssenbrugge, Annie; Bangsberg, David; Bloch, Kenneth D.; Boum, Yap; Zapol, Warren M.
    Children with cerebral malaria (CM) have high rates of mortality and neurologic sequelae. Nitric oxide (NO) metabolite levels in plasma and urine are reduced in CM. Methods. This randomized trial assessed the efficacy of inhaled NO versus nitrogen (N2) as an adjunctive treatment for CM patients receiving intravenous artesunate.We hypothesized that patients treated with NO would have a greater increase of the malaria biomarker, plasma angiopoietin-1 (Ang-1) after 48 hours of treatment. Results. Ninety-two children with CM were randomized to receive either inhaled 80 part per million NO or N2 for 48 or more hours. Plasma Ang-1 levels increased in both treatment groups, but there was no difference between the groups at 48 hours (P = not significant [NS]). Plasma Ang-2 and cytokine levels (tumor necrosis factor-α, interferon- γ, interleukin [IL]-1β, IL-6, IL-10, and monocyte chemoattractant protein-1) decreased between inclusion and 48 hours in both treatment groups, but there was no difference between the groups (P = NS). Nitric oxide metabolite levels—blood methemoglobin and plasma nitrate—increased in patients treated with NO (both P < .05). Seven patients in the N2 group and 4 patients in the NO group died. Five patients in the N2 group and 6 in the NO group had neurological sequelae at hospital discharge. Conclusions. Breathing NO as an adjunctive treatment for CM for a minimum of 48 hours was safe, increased blood methemoglobin and plasma nitrate levels, but did not result in a greater increase of plasma Ang-1 levels at 48 hours.

    Intimate Partner Violence and HIV Testing among Women in Rural South western Uganda
    (Journal of Clinical and Translational Science, 2021) Schember, Cassandra; Perkins, Jessica; Nyakato, Viola; Kakuhikire, Bernard; Kiconco, Allen; Namara, Betty; Brown, Lauren; Audet, Carolyn; Pettit, April; Bangsberg, David; Tsai, Alexander
    This research shows that physical intimate partner violence was associated with never testing for HIV while verbal intimate partner violence was associated with increased testing for HIV suggesting that HIV testing interventions should consider intimate partner violence prevention. OBJECTIVES/GOALS: HIV incidence is higher among women who experience intimate partner violence (IPV). However, few studies have assessed the association between HIV testing (regardless of the result) and the experience of IPV. Our objective was to assess the relationship between IPV and HIV testing among women from rural southwestern Uganda.

    Sociocultural and Structural Factors Contributing to Delays in Treatment for Children with Severe Malaria: A Qualitative Study in Southwestern Uganda
    (The American journal of tropical medicine and hygiene, 2015) Sundararajan, Radhika; Mwanga-Amumpaire, Juliet; Adrama, Harriet; Tumuhairwe, Jackline; Mbabazi, Sheilla; Mworozi, Kenneth; Carroll, Ryan; Bangsberg, David; Boum II, Yap; Ware, Norma C.
    Malaria is a leading cause of pediatric mortality, and Uganda has among the highest incidences in the world. Increased morbidity and mortality are associated with delays to care. This qualitative study sought to characterize barriers to prompt allopathic care for children hospitalized with severe malaria in the endemic region of southwestern Uganda. Minimally structured, qualitative interviews were conducted with guardians of children admitted to a regional hospital with severe malaria. Using an inductive and content analytic approach, transcripts were analyzed to identify and define categories that explain delayed care. These categories represented two broad themes: sociocultural and structural factors. Sociocultural factors were 1) interviewee’s distinctions of “traditional” versus “hospital” illnesses, which were mutually exclusive and 2) generational conflict, where deference to one’s elders, who recommended traditional medicine, was expected. Structural factors were 1) inadequate distribution of health-care resources, 2) impoverishment limiting escalation of care, and 3) financial impact of illness on household economies. These factors perpetuate a cycle of illness, debt, and poverty consistent with a model of structural violence. Our findings inform a number of potential interventions that could alleviate the burden of this preventable, but often fatal, illness. Such interventions could be beneficial in similarly endemic, low-resource settings.
