RESUMO
Poor retention in care is common among HIV-positive adults in sub-Saharan Africa settings and remains a key barrier to HIV management. We quantify the associations of disclosure of HIV status and referral to disclosure counseling with successful retention in care using data from three Cameroon clinics participating in the Phase 1 International epidemiologic Databases to Evaluate AIDS Central Africa cohort. Of 1646 patients newly initiating antiretroviral therapy between January 2008 and January 2011, 43% were retained in care following treatment initiation. Self-disclosure of HIV status to at least one person prior to treatment initiation was associated with a minimal increase in the likelihood of being retained in care (risk ratio [RR] = 1.14; 95% confidence interval (CI): 0.94, 1.38). However, referral to disclosure counseling was associated with a moderate increase in retention (RR = 1.37; 95% CI: 1.21, 1.55) and was not significantly modified by prior disclosure status (p = .3). Our results suggest that while self-disclosure may not significantly improve retention among patients receiving care at these Cameroon sites, counseling services may play an important role regardless of prior disclosure status.

Evidence demonstrates a substantial HIV epidemic among children and adolescents in countries with long-standing generalized HIV epidemics, where availability of prevention of mother-to-child transmission services has historically been limited. The objective of this research was to explore factors associated with antiretroviral therapy (ART) initiation and morbidity among HIV-infected surviving children 2-17 years of age attending HIV programs in Central Africa. Programmatic data from 404 children attending HIV programs in Burundi, Cameroon, and the Democratic Republic of Congo (DRC) were included in our evaluation. Children were followed prospectively from 2008 to 2011 according to each clinic's standard of care. Diagnosis at a reference hospital was significantly associated with not having initiated ART (adjusted odds ratio, AOR = 0.40; 95% confidence interval, CI, 0.24-0.67). Being seen at a clinic in Cameroon (AOR = 0.45; 95%CI = 0.24-0.85) and being in school were associated with decreased risk (AOR = 0.55; 95%CI = 0.31-0.96). Being ART-naïve (AOR = 1.88; 95%CI = 1.20-2.94) and being diagnosed at a reference hospital (AOR = 2.39; 95%CI = 1.29-4.41) or other testing facility (AOR = 2.86; 95%CI = 1.32-6.18) were associated with increased risk of having a morbid event at the initial visit. In longitudinal analysis of incident morbidity, we found a decreased risk associated with attending clinics in Cameroon (adjusted hazard ratio, AHR = 0.23; 95%CI = 0.11-0.46) and the DRC (AHR = 0.46; 95%CI = 0.29-0.74), and an increased risk associated with being ART-naïve (AHR = 1.83; 95%CI = 1.12-2.97). We found a high burden of HIV-related health problems among children receiving care in this setting. Children face significant barriers to accessing HIV services, and the HIV epidemic among surviving children in the Central African region has not been adequately evaluated nor addressed.

Antiretroviral therapy (ART)-naïve patients are vulnerable to becoming lost-to-care (LTC) because they are not monitored as often as patients on treatment. We examined data from 19,461 HIV positive adults at 10 HIV clinics in Democratic Republic of Congo (DRC), Cameroon, and Burundi participating in the Phase 1 International epidemiologic Databases to Evaluate AIDS Central Africa (IeDEA-CA) study. Patients were LTC if they were ART-naïve and did not return within 7 months of the end of data collection. Logistic regression was used to obtain odds ratios (ORs) and 95% confidence intervals (CIs) for risk factors associated with LTC. Of 5353 ART-naïve patients, 4420 (83%) were LTC and 933 (17%) were in-care. The odds of being LTC were greatest among patients from DRC (OR = 2.16, CI: 1.64-2.84, p < .0001), males (OR = 1.39, CI: 1.15-1.69, p = .0009), and ages 18-49 (OR = 1.45, CI: 1.16-1.82, p = .001). The odds of being LTC were least among patients with a WHO Clinical Stage of 1 or 2 (OR = 0.65, CI: 0.55-0.77, p < .0001) and in a perceived concordant relationship (OR = 0.61, CI: 0.43-0.87, p < .0001). LTC patients were more likely to have characteristics associated with higher risk for HIV transmission and progression. Many entered care at advanced stages and were less likely to know their partner's serostatus. Greater efforts to retain ART-naïve patients may increase earlier initiation of ART.

This study examines care seeking behaviors, clinical outcomes, and satisfaction with care of HIV-positive adults in Lubumbashi, DRC, one year after a disruption in care due to decreased global fund appropriations. We describe outcomes before and after the disruption. We compared characteristics of those who completed the survey and those who did not using the Wald F test. Most patients sought care after the disruption and continued antiretroviral therapy (ART), though use of cotrimoxizole prophylaxis declined. Though there was little change in WHO clinical stage at the new site of care, the majority of participants lost weight, adherence decreased, support group participation dropped, and satisfaction with care worsened. Patients were more likely to participate in the study if they were taking ART. This study highlights the importance of provider-patient communication during a transfer and the vulnerability of pre-ART patients to becoming lost to follow-up.

BACKGROUND: Retaining patients with HIV infection in care is still a major challenge in sub- Saharan Africa, particularly in the Democratic Republic of Congo (DRC) where the antiretroviral treatment (ART) coverage is low. Monitoring retention is an important tool for evaluating the quality of care. METHODS AND FINDINGS: A review of medical records of HIV-infected children was performed in three health facilities in the DRC: the Amo-Congo Health center, the Monkole Clinic in Kinshasa, and the HEAL Africa Clinic in Goma. Medical records of 720 children were included. Kaplan Meier curves were constructed with the probability of retention at 6 months, 1 year, 2 years and 3 years. Retention rates were: 88.2% (95% CI: 85.1%-90.8%) at 6 months; 85% (95% CI: 81.5%-87.6%) at one year; 79.4% (95%CI: 75.5%-82.8%) at two years and 74.7% (95% CI: 70.5%-78.5%) at 3 years. The retention varied across study sites: 88.2%, 66.6% and 92.5% at 6 months; 84%, 59% and 90% at 12 months and 75.7%, 56.3% and 85.8% at 24 months respectively for Amo-Congo/Kasavubu, Monkole facility and HEAL Africa. After multivariable Cox regression four variables remained independently associated with attrition: study site, CD4 cell count <350 cells/µL, children younger than 2 years and children whose caregivers were member of an independent church. CONCLUSIONS: Attrition remains a challenge for pediatric HIV positive patients in ART programs in DRC. In addition, the low coverage of pediatric treatment exacerbates the situation of pediatric HIV/AIDS.

BACKGROUND: Retention of patients in ART care is a major challenge in sub-Saharan programs. Retention is also one of the key indicators to evaluate the success of ART programs. METHODS AND FINDINGS: A retrospective review of 1500 randomly selected medical charts of adult ART patients from a local non-governmental (NGO) supported ART program in the Democratic Republic of Congo (DRC). Retention was defined as any visit to the clinic in the 4 months prior to the abstraction date. Retention over time and across different sites was described. The relationship between patient characteristics and retention rates at 1 year was also examined. 1450 patients were included in the analysis. The overall retention rates were 81.4% (95% CI: 79.3-83.4), 75.2% (95% CI: 72.8-77.3), 65.0% (95% CI: 62.3-67.6) and 57.2% (95% CI: 54.0-60.3) at 6 months, 1 year, 2 years and 3 years respectively. The retention rates between sites varied between 62.1% and 90.6% at 6 months and between 55.5% and 86.2% at 1 year. During multivariable analysis weight below 50 kg (aHR: 1.33, 95%CI: 1.05-1.69), higher WHO stage at initiation (aHR: 1.22, 95%CI 0.85-1.76 for stage 3 and aHR: 2.98, 95%CI: 1.93-4.59 for stage 4), and male sex (aHR: 1.32, 95%CI: 1.05-1.65) remained as significant risk factors for attrition during the first year after ART initiation. Other independent risk factors were year of initiation (aHR: 1.73, 95%CI: 1.26-2.38 for the year 2007 and aHR: 3.06, 95%CI: 2.26-4.14 for the period 2008-2009), and site. CONCLUSIONS: Retention is a major problem in DRC, while coverage of patients on ART is still very low. With the flattening of funding for HIV care and treatment in sub-Saharan Africa, and with decreasing funding worldwide, maximizing retention during the much needed scaling-up will even be more important.

INTRODUCTION: Despite recent advances in the management of HIV infection and increased access to treatment, prevention, care and support, the HIV/AIDS epidemic continues to be a major global health problem, with sub-Saharan Africa suffering by far the greatest humanitarian, demographic and socio-economic burden of the epidemic. Information on HIV/AIDS clinical care and established cohorts' characteristics in the Central Africa region are sparse. METHODS: A survey of clinical care resources, management practices and patient characteristics was undertaken among 12 adult HIV care sites in four countries of the International Epidemiologic Databases to Evaluate AIDS Central Africa (IeDEA-CA) Phase 1 regional network in October 2009. These facilities served predominantly urban populations and offered primary care in the Democratic Republic of Congo (DRC; six sites), secondary care in Rwanda (two sites) and tertiary care in Cameroon (three sites) and Burundi (one site). RESULTS: Despite some variation in facility characteristics, sites reported high levels of monitoring resources, including electronic databases, as well as linkages to prevention of mother-to-child HIV transmission programs. At the time of the survey, there were 21,599 HIV-positive adults (median age=37 years) enrolled in the clinical cohort. Though two-thirds were women, few adults (6.5%) entered HIV care through prevention of mother-to-child transmission services, whereas 55% of the cohort entered care through voluntary counselling and testing. Two-thirds of patients at sites in Cameroon and DRC were in WHO Stage III and IV at baseline, whereas nearly all patients in the Rwanda facilities with clinical stage information available were in Stage I and II. WHO criteria were used for antiretroviral therapy initiation. The most common treatment regimen was stavudine/lamivudine/nevirapine (64%), followed by zidovudine/lamivudine/nevirapine (19%). CONCLUSIONS: Our findings demonstrate the feasibility of establishing large clinical cohorts of HIV-positive individuals in a relatively short amount of time in spite of challenges experienced by clinics in resource-limited settings such as those in this region. Country differences in the cohort's site and patient characteristics were noted. This information sets the stage for the development of research initiatives and additional programs to enhance adult HIV care and treatment in Central Africa.

Background. Very little is known about older adults accessing HIV care in sub-Saharan Africa. Materials and Methods. Data were obtained from 18,839 HIV-positive adults at 10 treatment programs in Burundi, Cameroon, and the Democratic Republic of Congo. We compared characteristics of those aged 50+ with those aged 18-49 using chi-square tests. Logistic regression was used to determine if age was associated with medication adherence. Results. 15% of adults were 50+ years. Those aged 50+ were more evenly distributed between women and men (56% versus 44%) as compared to those aged 18-49 (71% versus 29%) and were more likely to be hypertensive (8% versus 3%) (P < 0.05). Those aged 50+ were more likely to be adherent to their medications than those aged 18-49 (P < 0.001). Adults who were not heavy drinkers reported better adherence as compared to those who reported drinking three or more alcoholic beverages per day (P < 0.001). Conclusions. Older adults differed from their younger counterparts in terms of medication adherence, sociodemographic, behavioral, and clinical characteristics.
