Correlates of ever had sex among perinatally HIV-infected adolescents in Uganda
Background:
The objective of this study was to explore the correlates of ever had sex among perinatally HIV-infected PHIV) adolescents.
Methods:
A cross-sectional survey of sexual behaviour was conducted with 624 PHIV adolescents living three regions 12 districts) of Uganda. Data was collected on socio demographic characteristics (age, sex, occupation, religion and education status), sexual practices and behaviours (Intimate relationships, sexual intercourse, age of sexual debut, condom use, multiple and concurrent sexual partners), consequences of sexual behaviours (pregnancy and STI’s) and life style factors (use of alcohol, psychoactive substances and peer influence). Multivariable logistic-regression was used to ascertain the determinants of sexual activity.
Results:
The majority of PHIV were female (59.3 %) and the mean age of the sample was 16.2 (±2.1) years. The mean age of sexual debut was 15.8 years; 16.2 % (101/624) reported symptoms for sexually transmitted infections (STI) and more than a third (213/624) reported ever had sex. Of these 76.5 % (165/213) used condoms inconsistently; and 49.3 % (105/213) had been pregnant or made someone pregnant. Of those in relationships, 56.3 % (223/396) did not disclose and were not aware of their partners’ HIV status. Adolescents aged 15–19 years were more likely to have ever been sexually active (Adjusted odds ratio (AOR) 6.28, 95 % Confidence interval (CI): 2.63-14.99) compared to those aged 10–14 years. Adolescents who were living alone were more likely to have ever been sexually active compared to those living with one or both parents (AOR 4.33, 95 % CI: 1.13-16.62). The odds of being sexually active were lower among adolescents in school compared to those out of school (AOR 0.2, 95 % CI:0.13-0.30), who had never been treated for STI (compared to those who had never been treated for STI) (AOR 0.19, 95 % 0.11-0.32) and adolescents who never drank alcohol (AOR 0.49, 95 % CI 0.28-0.87).
Conclusion:
PHIV adolescents have risky sexual behaviours charac terized by being sexually active, inconsistent condom use, and having partners of unknown status. Risk reduction interventions are required to minimize unplanned pregnancies, STI, and HIV transmission by PHIV adolescents

Potential for false positive HIV test results with the serial rapid HIV testing algorithm
Background: Rapid HIV tests provide same-day results and are widely used in HIV testing programs in areas with limited personnel and laboratory infrastructure. The Uganda Ministry of Health currently recommends the serial rapid testing algorithm with Determine, STAT-PAK, and Uni-Gold for diagnosis of HIV infection. Using this algorithm, individuals who test positive on Determine, negative to STAT-PAK and positive to Uni-Gold are reported as HIV positive. We conducted further testing on this subgroup of samples using qualitative DNA PCR to assess the potential for false positive tests in this situation. Results: Of the 3388 individuals who were tested, 984 were HIV positive on two consecutive tests, and 29 were considered positive by a tiebreaker (positive on Determine, negative on STAT-PAK, and positive on Uni-Gold). However, when the 29 samples were further tested using qualitative DNA PCR, 14 (48.2%) were HIV negative. Conclusion: Although this study was not primarily designed to assess the validity of rapid HIV tests and thus only a subset of the samples were retested, the findings show a potential for false positive HIV results in the subset of individuals who test positive when a tiebreaker test is used in serial testing. These findings highlight a need for confirmatory testing for this category of individuals
Abbreviated HIV counselling and testing and enhanced referral to care in Uganda: a factorial randomised controlled trial
Background 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.
Methods 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).
Findings 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).
Interpretation Abbreviated HIV counselling and testing did not adversely aff ect risk behaviour. Linkage to care
interventions might decrease time to enrolment in HIV care and antiretroviral treatment and thus might aff ect
secondary HIV transmission and improve treatment outcomes

Research translation to inform national health policies: learning from multiple perspectives in Uganda
<p>Abstract</p> <p>Background</p> <p>Research and evidence can have an impact on policy and practice, resulting in positive outcomes. However, research translation is a complex, dynamic and non-linear process. Although universities in Africa play a major role in generating research evidence, their strategic approaches to influence health policies and decision making are weak. This study was conducted with the aim of understanding the process of translating research into policy in order to guide the strategic direction of Makerere University College of Health Sciences (MakCHS) and similar institutions in their quest to influence health outcomes nationally and globally.</p> <p>Methods</p> <p>A case study approach using 30 in-depth interviews with stakeholders involved in two HIV prevention research project was purposively selected. The study sought to analyze the research-to-policy discourses for the prevention of mother-to-child transmission (PMTCT) and safe male circumcision (SMC). The analysis sought to identify entry points, strengths and challenges for research-to-policy processes by interviewing three major groups of stakeholders in Uganda – researchers (8), policy makers (12) and media practitioners (12).</p> <p>Results</p> <p>Among the factors that facilitated PMTCT policy uptake and continued implementation were: shared platforms for learning and decision making among stakeholders, implementation pilots to assess feasibility of intervention, the emerging of agencies to undertake operations research and the high visibility of policy benefits to child survival. In contrast, SMC policy processes were stalled for over two years after the findings of the Uganda study was made public. Among other factors, policy makers demanded additional research to assess implementation feasibility of SMC within ordinary health system context. High level leaders also publicly contested the SMC evidence and the underlying values and messages – a situation that reduced the coalition of policy champions.</p> <p>Conclusions</p> <p>This study shows that effective translation of PMTCT and SMC research results demanded a “360 degree” approach to assembling additional evidence to inform the implementation feasibility for these two HIV prevention interventions. MakCHS and similar institutions should prioritize implementation research to guide the policy processes about the feasibility of implementing new and effective innovations (e.g. PMTCT or SMC) at a large scale in contexts that may be different from the research environments.</p
Low HIV testing rates among tuberculosis patients in Kampala, Uganda
<p>Abstract</p> <p>Background</p> <p>HIV testing among tuberculosis patients is critical in improving morbidity and mortality as those found to be HIV positive will be offered a continuum of care including ART if indicated. We conducted a cross-sectional study in three Kampala City primary care clinics: to assess the level of HIV test uptake among newly diagnosed pulmonary tuberculosis (PTB) patients; to assess patient and health worker factors associated with HIV test uptake; and to determine factors associated with HIV test uptake at the primary care clinics</p> <p>Methods</p> <p>Adult patients who had been diagnosed with smear-positive PTB at a primary care clinic or at the referral hospital and who were being treated at any of the three clinics were interviewed. Associations between having taken the test as the main outcome and explanatory variables were assessed by multivariate logistic regression.</p> <p>Results</p> <p>Between April and October 2007, 112 adults were included in the study. An HIV test had been offered to 74 (66%). Of the 112 patients, 61 (82%) had accepted the test; 45 (74%) had eventually been tested; and 32 (29%) had received their test results.</p> <p>Patients who were <25 yeas old, female or unemployed, or had reported no previous HIV testing, were more likely to have been tested. The strongest predictor of having been tested was if patients had been diagnosed at the referral hospital compared to the city clinic (adjusted OR 24.2; 95% CI 6.7-87.7; p < 0.001). This primarily reflected an "opt-out" (uptake 94%) versus an "opt-in" (uptake 53%) testing policy.</p> <p>Conclusions</p> <p>The overall HIV test uptake was surprisingly low at 40%. The HIV test uptake was significantly higher among TB patients who were identified at hospital, among females and in the unemployed.</p
Predictors of linkage to care following community-based HIV counseling and testing in rural Kenya
Despite innovations in HIV counseling and testing (HCT), important gaps remain in understanding linkage to care. We followed a cohort diagnosed with HIV through a community-based HCT campaign that trained persons living with HIV/AIDS (PLHA) as navigators. Individual, interpersonal, and institutional predictors of linkage were assessed using survival analysis of self-reported time to enrollment. Of 483 persons consenting to follow-up, 305 (63.2%) enrolled in HIV care within 3 months. Proportions linking to care were similar across sexes, barring a sub-sample of men aged 18–25 years who were highly unlikely to enroll. Men were more likely to enroll if they had disclosed to their spouse, and women if they had disclosed to family. Women who anticipated violence or relationship breakup were less likely to link to care. Enrolment rates were significantly higher among participants receiving a PLHA visit, suggesting that a navigator approach may improve linkage from community-based HCT campaigns.Vestergaard Frandse
