High rates of viral suppression in a cohort of HIV-positive adults receiving ART in Ethiopian health centers irrespective of concomitant tuberculosis.

ABSTRACT: Antiretroviral therapy (ART) initiation during treatment for tuberculosis (TB) improves survival in HIV/TB co-infected patients. Data on ART outcome for HIV/TB co-infected patients managed in primary health care in low-income regions is limited. We compared virological suppression rates, mortality and retention in care in HIV-positive adults receiving care in five Ethiopian health centres with regard to TB co-infection.HIV-positive ART-naïve adults eligible for ART initiation were prospectively recruited from October 2011 until March 2013. At inclusion, all patients submitted sputum for microbiological TB testing (smear microscopy, liquid culture and PCR). Virological suppression rates after six months of ART (VS; viral load <40 and <400 copies/mL) with regard to TB status was the primary outcome. The impact of HIV/TB co-infection on VS rates was determined by multivariate regression analysis. Mortality and retention in care were analyzed by proportional hazard models.Among 812 participants (TB 158; non-TB 654), 678 started ART during the follow-up period (TB 135; non-TB 543). Median CD4 cell counts at ART initiation were 161 cells/µL (interquartile range [IQR], 98-243) and 184 (IQR, 118-256) for TB and non-TB patients, respectively (p=0.05). No difference in retention in care between TB and non-TB patients was observed during follow-up; 25 (3.7%) patients died and 17 (2.5%) were lost to follow-up (p=0.30 and p=0.83, respectively). Overall rates of VS at six months were 72.1% (<40 copies/mL) and 88.7% (<400 copies/mL), with similar results for subjects with and without TB co-infection (<40 copies/mL: 65/92 (70.7%) vs. 304/420 (72.4%), p=0.74; <400 copies/mL: 77/92 (83.7%) vs. 377/420 (89.8%), p=0.10, respectively). CD4 cell count increase during treatment was 87 (IQR, 26-178) and 103 cells/µL (IQR, 38-173) for TB and non-TB patients, respectively, with no significant difference between the two groups (p=0.49).High rates of VS were achieved in adults receiving ART at Ethiopian health centres managed by non-physician clinicians, with no significant difference with regard to TB co-infection. These findings demonstrate the feasibility of combined ART and anti-TB treatment at primary health care level in low-income countries. This study is registered with clinicaltrial.gov, NCT01433796.

Project description:BackgroundTuberculosis (TB) and HIV makeup a deadly synergy of infectious disease, and the combined effect is apparent in resource limited countries like Ethiopia. Previous studies have demonstrated inconsistent results about the protective effect of isoniazid preventive therapy (IPT) on active TB incidence among HIV positive patients receiving ART. Therefore, the aim of this meta-analysis was, first, to determine the protective effect of IPT on active tuberculosis incidence, and second, to assess the pooled incidence of active TB among HIV positive patients taking ART with and without IPT intervention in Ethiopia.MethodsPubMed, Google scholar and Cochran library databases were searched from April 1 to 30, 2018. Two independent authors explored and assessed studies for eligibility, and extracted data based on predefined criteria. Studies that reported TB incidence among HIV positive patients taking ART in Ethiopia with and without IPT concomitant intervention, and with a clear stratified data on the incidence of TB based on the duration of IPT intervention were selected. A random effects model was used to estimate risk ratios and the pooled incident TB with the respective 95% confidence intervals.ResultsWe identified 7 suitable studies in this analysis. Accordingly, IPT reduced the risk of TB incidence by 74%, risk ratio (RR) 0.26 (95% CI; 0.16-0.43%), compared to no IPT group. Moreover, IPT for 12 months reduced incident TB by 91% (RR: 0.09, 95% CI: 0.04 to 0.21), whereas 6 months IPT averted TB incidence by 63% (RR: 0.37, 95% CI: 0.26 to 0.52). The overall pooled incident TB among HIV infected patients receiving ART was 10.30% (95% CI; 7.57-13.02%). Specifically, incident TB among study cohorts with and without IPT was 3.79% (95% CI; 2.03-5.55%) and 16.32% (95% CI; 11.57-21.06%) respectively.ConclusionIPT reduced the risk of incident TB among HIV positive patients receiving ART in Ethiopian settings. Moreover, the duration of IPT intervention has effect on its protective role. Thus, scaling up the isoniazid preventive therapy program and its strict compliance is necessary to avert HIV fueled tuberculosis.Study protocol registrationCRD42018090804.

Project description:IntroductionMental health problems are prevalent in adolescents living with HIV (ALHIV), often remain untreated, and may negatively affect antiretroviral therapy (ART) adherence and viral suppression. We implemented routine mental health screening at a paediatric ART clinic to improve the identification and management of mental health problems in ALHIV. In this report, we examine screening outcomes, associated patient characteristics and the odds of unsuppressed viral load in ALHIV screening positive for mental disorders.MethodsAdolescents aged 10 to 19 years attending Rahima Moosa Hospital in Johannesburg, South Africa between February 1, 2018, and January 1, 2020, were offered mental health screening at each routine HIV care visit. The screening included four pre-screening questions followed by full screening (conditional on positive pre-screening) for depression (Patient Health Questionnaire-9 [PHQ-9]), suicide (Adolescent Innovations Project [AIP]-handbook), anxiety (Generalized Anxiety Disorder-7 [GAD-7]), post-traumatic stress disorder (PTSD) (Primary Care PTSD Screen [PC-PTSD-5]) and substance use (CAGE Adapted to Include Drugs [CAGE-AID]). We assessed screening outcomes and calculated adjusted odds ratios for associations between positive screening tests at the first screen and unsuppressed viral load (>400 copies/mL) at the measurement taken closest to the date of screening, within hundred days before and one day after screening.ResultsOut of 1203 adolescents who attended the clinic, 1088 (90.4%) were pre-screened of whom 381 (35.0%) underwent full screening, 48 (4.4%) screened positive for depression (PHQ-9 ≥10), 29 (2.8%) for suicidal concern, 24 (2.2%) for anxiety (GAD-7 ≥10), 38 (3.2%) for PTSD (PC-PTSD-5 ≥3), 18 (1.7%) for substance use (CAGE-AID ≥2) and 97 (8.9%) for any of these conditions. Positive screening for depression (aOR 2.39, 95% CI 1.02 to 5.62), PTSD (aOR 3.18, 95% CI 1.11 to 9.07), substance use (aOR 7.13, 95% CI 1.60 to 31.86), or any condition (aOR 2.17, 95% CI 1.17 to 4.02) were strongly associated with unsuppressed viral load.ConclusionsALHIV affected by mental health problems have increased rates of unsuppressed viral load and need specific clinical attention. The integration of routine mental health screening in paediatric ART programmes is a feasible approach for identifying and referring adolescents with mental health and adherence problems to counselling and psychosocial support services and if needed to psychiatric care.

Project description:The 2015 WHO recommendation of antiretroviral therapy (ART) for all HIV-positive persons calls for treatment initiation in millions of persons newly eligible with high CD4+ counts. Efficient and effective care models are urgently needed for this population. We evaluated clinical outcomes of asymptomatic HIV-positive adults and children starting ART with high CD4+ counts using a novel streamlined care model in rural Uganda and Kenya.In the 16 intervention communities of the HIV test-and-treat Sustainable East Africa Research for Community Health Study (NCT01864603), all HIV-positive individuals irrespective of CD4 were offered ART (efavirenz [EFV]/tenofovir disoproxil fumarate + emtricitabine (FTC) or lamivudine (3TC). We studied adults (?fifteen years) with CD4 ? 350/?L and children (two to fourteen years) with CD4 > 500/?L otherwise ineligible for ART by country guidelines. Clinics implemented a patient-centred streamlined care model designed to reduce patient-level barriers and maximize health system efficiency. It included (1) nurse-conducted visits with physician referral of complex cases, (2) multi-disease chronic care (including for hypertension/diabetes), (3) patient-centred, friendly staff, (4) viral load (VL) testing and counselling, (5) three-month return visits and ART refills, (6) appointment reminders, (7) tiered tracking for missed appointments, (8) flexible clinic hours (outside routine schedule) and (9) telephone access to clinicians. Primary outcomes were 48-week retention in care, viral suppression (% with measured week 48 VL ? 500 copies/mL) and adverse events. Results Overall, 972 HIV-positive adults with CD4+ ? 350/?L initiated ART with streamlined care. Patients were 66% female and had median age thirty-four years (IQR, 28-42), CD4+ 608/?L (IQR, 487-788/?L) and VL 6775 copies/mL (IQR, <500-37,003 c/mL). At week 48, retention was 92% (897/972; 2 died/40 moved/8 withdrew/4 transferred care/21/964 [2%] were lost to follow-up). Viral suppression occurred in 778/838 (93%) and 800/972 (82%) in intention-to-treat analysis. Grade III/IV clinical/laboratory adverse events were rare: 95 occurred in 74/972 patients (7.6%). Only 8/972 adults (0.8%) switched ART from EFV to lopinavir (LPV) (n = 2 for dizziness, n = 2 for gynaecomastia, n = 4 for other reasons). Among 83 children, week 48 retention was 89% (74/83), viral suppression was 92% (65/71) and grade III/IV adverse events occurred in 4/83 (4.8%).Using a streamlined care model, viral suppression, retention and ART safety were high among asymptomatic East African adults and children with high CD4+ counts initiating treatment.NCT01864603.
