A Comparative Study on Effect of Caregivers Training on Health Outcomes of HIV Infected Children on Antiretroviral Therapy in Kenya
The purpose of this cohort study was to assess the effect of caregiver training on health outcomes of HIV-infected children aged 1-14 years on antiretroviral therapy in South Rift Valley, Kenya. Three hundred and twenty children of trained caregivers and 778 children of non-trained caregivers were targeted from four hospitals. Population proportionate to size sampling technique was used to calculate number of children enrolled. Children medical chart for trained and non-trained caregivers were stratified as per year of training, 2014, 2015, 2016 and randomly selected numbers matched with corresponding medical record. Data was collected through review of medical records, questionnaires and caregivers interview. There was significant association between caregiver training and adherence (Fisher's Exact Test X2 =22.740, p = .001). Children of trained caregivers had significant reductions in viral load (Kruskal Wallis X2 =7.124, p = .028); significant difference in viral loads was also observed between trained and non-trained caregivers (Mann-Whitney U=19846, p=.012), significant association in episodes of opportunistic infections before, after and among non-trained caregivers (Fisher's Exact Test X2 =76.768, p = .001). Nutritional status of children was not associated with caregivers training (Pearson Chi-square X2 = 11.616, p =.072). Most caregivers perceived training to be useful. The study found that, training enables caregivers to improve adherence levels of HIV infected children on antiretroviral therapy. Even though there are HIV information in public domain, the study found, if this information is provided in a structured manner, enables suppression of viral loads of HIV infected children. Training caregivers significantly reduces frequency of opportunistic infections among HIV infected children on antiretroviral therapy. Providing information on nutrition to caregivers does not affect nutritional status of HIV infected children. Training caregivers on HIV information improves health outcomes of HIV infected children thus study provide evidence–based decision making in rolling out caregivers training nationally.

Successes and Challenges in an Integrated Tuberculosis/HIV Clinic in a Rural, Resource-Limited Setting: Experiences from Kericho, Kenya
Objective. To describe TB/HIV clinic outcomes in a rural, Ministry of Health hospital.
Design. Retrospective, secondary analyses. Descriptive statistics and logistic regression analyses evaluated baseline characteristics and outcomes.
Results. Of 1,911 patients, 89.8% were adults aged 32.0 (±12.6) years with baseline CD4 = 243.3 (±271.0), 18.2% < 50 cells/mm3. Pulmonary (84.8%, (32.2% smear positive)) exceeded extrapulmonary TB (15.2%). Over 5 years, treatment success rose from 40.0% to 74.6%, lost to follow-up dropped from 36.0% to 12.5%, and deaths fell from 20.0% to 5.4%. For patients starting ART after TB treatment, those with CD4 ≥ 50 cells/mm3 were twice as likely to achieve treatment success (OR = 2.0, 95% CI = 1.3–3.1) compared to those with CD4 < 50 cells/mm3. Patients initiating ART at/after 2 months were twice as likely to achieve treatment success (OR = 2.0, 95% CI = 1.3–3.3). Yearly, odds of treatment success improved by 20% (OR = 1.2, 95% CI = 1.0–1.5).
Conclusions. An integrated TB/HIV clinic with acceptable outcomes is a feasible goal in resource-limited settings

Persons living with HIV in sero-discordant partnerships experience improved HIV care engagement compared with persons living with HIV in sero-concordant partnerships: a cross-sectional analysis of four African countries
Background
Persons living with HIV (PLWH) who are members of sero-discordant and sero-concordant relationships may experience psychological stressors or motivators that affect HIV care. We assessed the association between sero-discordance status, antiretroviral therapy (ART) uptake, and viral suppression in the African Cohort Study (AFRICOS).
Methods
AFRICOS enrolls PLWH and HIV-uninfected individuals at 12 sites in Uganda, Kenya, Tanzania, and Nigeria. At enrollment, we determined ART use through self-report. Viral suppression was defined as HIV RNA < 1000 copies/mL. We analyzed PLWH who were index participants within two types of sexual dyads: sero-discordant or sero-concordant. Binomial regression models were used to estimate prevalence ratios (PRs) and 95% confidence intervals (95% CIs) for factors associated with ART use and viral suppression at study enrollment.
Results
From January 2013 through March 2018, 223 index participants from sero-discordant dyads and 61 from sero-concordant dyads were enrolled. The majority of the indexes were aged 25–34 years (50.2%), female (53.4%), and married (96.5%). Sero-discordant indexes were more likely to disclose their status to partners compared with sero-concordant indexes (96.4% vs. 82.0%, p < 0.001). After adjustment, sero-discordant index participants were more likely to be on ART (aPR 2.8 [95% CI 1.1–6.8]), but no more likely to be virally suppressed. Results may be driven by unique psycho-social factors and global implementation of treatment as prevention.
Conclusions
PLWH in sero-discordant sexual partnerships demonstrated improved uptake of ART compared with those in sero-concordant partnerships. Interventions are needed to increase care engagement by individuals in sero-concordant relationships to improve HIV outcomes
Frequency and Predictors of HIV-Related Cognitive Impairment in East Africa: The Africa Cohort Study (AFRICOS).
BackgroundMedication adherence is a critical issue in achieving viral suppression targets, particularly in resource-limited countries. As HIV-related cognitive impairment (CI) impacts adherence, we examined frequency and predictors of CI in the African Cohort Study.SettingCross-sectional examination of enrollment data from President's Emergency Plan for AIDS Relief supported clinic sites.MethodsIn a 30-minute cognitive assessment, CI was defined as -1SD on 2 tests or -2SD on one, as compared with 429 controls. We performed univariable and multivariable logistic and linear models examining clinical and demographic factors associated with CI and global neuropsychological performance (NP-6).ResultsTwo thousand four hundred seventy-two HIV+ participants from Kenya (n = 1503), Tanzania (n = 469), and Uganda (n = 500). The mean (SD) age was 39.7 (10.7) years, and 1452 (59%) were women. The majority reported completing or partially completing primary school (n = 1584, 64%). Mean (SD) current and nadir CD4 count were 463 (249) and 204 (221) cells/mm, respectively; 1689 (68%) were on combination antiretroviral therapy. Nine hundred thirty-nine (38%) HIV+ versus 113 (26%) HIV- individuals showed CI: (P < 0.001). We found significant effects of literacy [odds ratio (OR): 0.3; 95% CI: 0.2 to 0.4; P < 0.001] and World Health Organization stage 4 (OR: 1.5; 95% CI: 1.0 to 2.q; P = 0.046) on CI. Tanzanians (OR: 3.2; 95% CI: 2.4 to 4.3; P < 0.001) and Kenyans (OR: 2.0; 95% CI: 1.6 to 2.6; P < 0.001) had higher risk of CI compared with Ugandans. Results were relatively unchanged in predictive models of NP-6, with the only difference being an additional significant effect of current CD4 cell count (coeff: 0.0; 95% CI: 0.0 to 0.0; P = 0.005).ConclusionsLiteracy, country, World Health Organization stage, and current CD4 cell count were associated with increased risk of cognitive dysfunction. Our findings help optimize care practices in Africa, illustrating the importance of strategies for early and effective viral-immunological control

Monocyte activation, HIV, and cognitive performance in East Africa
Chronic inflammation associated with monocyte activation has been linked to HIV-related cognitive outcomes in resource-rich settings. Few studies have investigated this relationship in the African context where endemic non-HIV infections may modulate effects. We characterized immune activation biomarkers in Kenyan and Ugandan participants in relation to neuropsychological testing performance (NTP) from the African Cohort Study (AFRICOS). We focused on activation markers associated with monocytes (sCD14, sCD163, neopterin), T cells (HLA-DR+CD38+ on CD4+ and CD8+ T lymphocytes), and microbial translocation (intestinal fatty acid-binding protein, I-FABP). The HIV-infected (n = 290) vs. HIV-uninfected (n = 104) groups were similar in age with mean (SD) of 41 (9.5) vs. 39 (9.9) years, respectively (p = 0.072). Among HIV-infected participants, the mean (SD) current CD4+ count was 402 (232); 217 (75%) were on combination antiretroviral therapy (cART) and 199 (69%) had suppressed plasma HIV RNA. sCD14 was inversely correlated to NTP (r = - 0.14, p = 0.037) in models that included both HIV-infected and uninfected individuals, adjusted for HIV status and research site, whereas sCD163 was not (r = 0.041, p = 0.938). Neither of the T cell activation markers correlated with NTP. In the HIV-infected group, I-FABP was inversely associated with NTP (r = - 0.147, p = 0.049), even among those with suppressed plasma virus (r = - 0.0004, p = 0.025). Among the full group, HIV status did not appear to modulate the effects observed. In this cohort from East Africa, sCD14, but not sCD163, is associated with cognitive performance regardless of HIV status. Findings among both HIV-infected and HIV-uninfected groups is supportive that HIV and non-HIV-related inflammatory sources contribute to cognitive performance in this setting

Perinatal Depressive Symptoms and Viral Non-suppression Among a Prospective Cohort of Pregnant Women Living with HIV in Nigeria, Kenya, Uganda, and Tanzania
Depression is common during pregnancy and is associated with reduced adherence to HIV-related care, though little is known about perinatal trajectories of depression and viral suppression among women living with HIV (WLHV) in sub-Saharan Africa. We sought to assess any association between perinatal depressive symptoms and viral non-suppression among WLWH. Depressive symptomatology and viral load data were collected every 6 months from WLWH enrolled in the African Cohort Study (AFRICOS; January 2013-February 2020). Generalized estimating equations modeled associations between depressive symptoms [Center for Epidemiological Studies Depression (CES-D) ≥ 16] and viral non-suppression. Of 1722 WLWH, 248 (14.4%) had at least one pregnancy (291 total) and for 61 pregnancies (21.0%), women reported depressive symptoms (13.4% pre-conception, 7.6% pregnancy, 5.5% one-year postpartum). Depressive symptomatology was associated with increased odds of viral non-suppression (aOR 2.2; 95% CI 1.2-4.0, p = 0.011). Identification and treatment of depression among women with HIV may improve HIV outcomes for mothers
Clinical similarities and differences between two large HIV cohorts in the United States and Africa
BACKGROUND: Washington, DC, and sub-Saharan Africa are both affected by generalized HIV epidemics. However, care for persons living with HIV (PLWH) and clinical outcomes may differ in these geographically and culturally diverse areas. We compared patient and clinical site characteristics among adult persons living with HIV (PLWH) enrolled in two longitudinal HIV cohort studies-the African Cohort Study (AFRICOS) and the DC Cohort. METHODS: The DC Cohort is a clinic-based city-wide longitudinal cohort comprised of PLWH attending 15 HIV clinics in Washington, DC. Patients\u27 socio-demographic characteristics, clinical evaluations, and laboratory data are retrospectively collected from electronic medical records and limited manual chart abstraction. AFRICOS is a prospective observational cohort of PLWH and uninfected volunteers attending 12 select HIV care and treatment facilities in Nigeria, Kenya, Uganda and Tanzania. AFRICOS study participants are a subset of clinic patients who complete protocol-specific visits every 6 months with history and physical examination, questionnaire administration, and blood/sputum collection for ascertainment of HIV outcomes and comorbidities, and neurocognitive and functional assessments. Among participants aged ≥ 18 years, we generated descriptive statistics for demographic and clinical characteristics at enrollment and follow up and compared them using bivariable analyses. RESULTS: The study sample included 2,774 AFRICOS and 8,420 DC Cohort participants who enrolled from January 2013 (AFRICOS)/January 2011 (DC Cohort) through March 2018. AFRICOS participants were significantly more likely to be women (58.8% vs 27.1%) and younger (83.3% vs 61.1% aged \u3c 50 years old) and significantly less likely to be MSM (only 0.1% of AFRICOS population reported MSM risk factor) than DC Cohort. Similar rates of current viral suppression (about 75% of both samples), hypertension, hepatitis B coinfection and alcohol use were observed. However, AFRICOS participants had significantly higher rates of CD4\u3c200 and tuberculosis and significantly lower rates of obesity, DM, hepatitis C coinfection and syphilis. CONCLUSIONS: With similar viral suppression outcomes, but many differences between our cohorts noted, the combined sample provides unique opportunities to assess and compare HIV care and treatment outcomes in the U.S. and sub-Saharan Africa. Comparing these two cohorts may inform care and treatment practices and may pave the way for future pathophysiologic analyses
Diagnosis disclosure to adolescents living with HIV in rural Kenya improves antiretroviral therapy adherence and immunologic outcomes: A retrospective cohort study
<div><p>Background & aims</p><p>Emphasis on adolescent HIV has increased worldwide as antiretroviral treatment has greatly extended life expectancies of HIV-positive children. Few evidence-based guidelines exist on the optimal time to disclose to an adolescent living with HIV (ALHIV); little is known about the medical effects of disclosure. This study looked to determine whether disclosure is associated with improved medical outcomes in ALHIV. Prior work has tended to be qualitative, cross-sectional, and with an emphasis on psychosocial outcomes. This paper addresses the adolescent cohort retrospectively (longitudinally), building upon what is already known about disclosure.</p><p>Methods</p><p>Retrospective, longitudinal clinical record reviews of ALHIV seen at Kericho District Hospital between April 2004 and November 2012 were performed. Patient demographics and clinical outcomes were systematically extracted. The student’s t-test was used to calculate changes in mean CD4 count, antiretroviral therapy (ART), and cotrimoxazole adherence pre- vs. post-disclosure. Linear regression modelling assessed for trends in those clinical outcomes associated with age of disclosure.</p><p>Results</p><p>Ninety-six ALHIV (54 female, 42 male) were included; most (73%) entered care through the outpatient department. Nearly half were cared for by parents, and 20% experienced a change in their primary caregiver. The mean time in the study was 2.47 years; mean number of visits 10.97 per patient over the mean time in the study. Mean disclosure age was 12.34 years. An increase in mean ART adherence percentage was found with disclosure (0.802 vs. 0.917; p = 0.0015). Younger disclosure age was associated with significantly higher mean CD4 counts over the course of the study (p = 0.001), and a nonsignificant trend toward a higher mean ART adherence percentage (p = 0.055).</p><p>Conclusion</p><p>ART adherence and improved immunologic status are both associated with disclosure of HIV infection to adolescent patients. Disclosure of an HIV diagnosis to an adolescent is an important means to improve HIV care.</p></div
