RESUMO

High rates of non-nucleoside reverse transcriptase inhibitors (NNRTI) resistance was a key consideration in the WHO policies transitioning first-line regimens to include integrase inhibitors (dolutegravir [DTG]). However, recent data suggests a relationship between DTG and neural tube defects among women exposed during conception, giving providers and policymakers pause regarding the planned regimen changes. We examined HIV drug resistance among a cohort of 46 acutely infected persons in Malawi. Our data demonstrates high levels of transmitted resistance, 11% using standard resistance surveillance mutations and 20% when additional NNRTI polymorphisms that may affect treatment response are included. High resistance rates in this treatment-naïve patient population reinforces the critical nature of DTG-based options in the context of public-health driven treatment programs.

RESUMO

Africa is experiencing an increasing prevalence of noncommunicable diseases (NCD). However, few reliable data are available on their true burden, main risk factors, and economic impact that are needed to inform implementation of evidence-based interventions in the local context. In Malawi, a number of initiatives have begun addressing the NCD challenge, which have often utilized existing infectious disease infrastructure. It will be crucial to carefully leverage these synergies to maximize their impact. NCD-BRITE (Building Research Capacity, Implementation, and Translation Expertise) is a transdisciplinary consortium that brings together key research institutions, the Ministry of Health, and other stakeholders to build long-term, sustainable, NCD-focused implementation research capacity. Led by University of Malawi-College of Medicine, University of North Carolina, and Dignitas International, NCD-BRITE's specific aims are to conduct detailed assessments of the burden and risk factors of common NCD; assess the research infrastructure needed to inform, implement, and evaluate NCD interventions; create a national implementation research agenda for priority NCD; and develop NCD-focused implementation research capacity through short courses, mentored research awards, and an internship placement program. The capacity-building activities are purposely designed around the University of Malawi-College of Medicine and Ministry of Health to ensure sustainability. The NCD BRITE Consortium was launched in February 2018. In year 1, we have developed NCD-focused implementation research capacity. Needs assessments will follow in years 2 and 3. Finally, in year 4, the generated research capacity, together with findings from the needs assessments, will be used to create a national, actionable, implementation research agenda for NCD prioritized in this consortium, namely cardiovascular disease, diabetes mellitus, and asthma and chronic obstructive pulmonary disease.

RESUMO

HIV serodisclosure to sexual partners is an important aspect of HIV prevention, treatment, and care. We investigated the association between partnership duration and serodisclosure among HIV-infected individuals in Lilongwe, Malawi. We analyzed data from a cross-sectional study of individuals attending one of two antiretroviral therapy (ART) clinics in Lilongwe. Clients aged 18-45 years and sexually active within the past six months were eligible. Logistic regression was used to estimate the odds ratio (OR) and 95% confidence interval (CI) for the association between partnership duration ≤1 year and serodisclosure. Five hundred and sixty-two participants completed the survey: 308 (55%) women and 254 (45%) men. Median age was 35 years (IQR 30-40), 90% were married, 88% were on ART, and 95% had serodisclosed to their partner. Marital status, knowledge of partner serostatus, and ART use were significantly associated with serodisclosure. Participants in a relationship for ≤1 year were significantly less likely to disclose their serostatus to their partners compared to those in a relationship for >1 year (OR = 0.18, 95% CI: 0.06, 0.58). Couple-based interventions that encourage serodisclosure among partners within their first year of relationship should be developed to decrease HIV transmission, encourage treatment and support.

RESUMO

BACKGROUND: We investigated 18-month incidence and determinants of death and loss to follow-up of children after antiretroviral therapy (ART) initiation in a multiregional collaboration in lower-income countries. METHODS: HIV-infected children (positive polymerase chain reaction <18 months or positive serology ≥18 months) from International Epidemiologic Databases to Evaluate AIDS cohorts, <16 years, initiating ART were eligible. A competing risk regression model was used to analyze the independent risk of 2 failure types: death and loss to follow-up (>6 months). FINDINGS: Data on 13,611 children, from Asia (N = 1454), East Africa (N = 3114), Southern Africa (N = 6212), and West Africa (N = 2881) contributed 20,417 person-years of follow-up. At 18 months, the adjusted risk of death was 4.3% in East Africa, 5.4% in Asia, 5.7% in Southern Africa, and 7.4% in West Africa (P = 0.01). Age < 24 months, World Health Organization stage 4, CD4 < 10%, attending a private sector clinic, larger cohort size, and living in West Africa were independently associated with poorer survival. The adjusted risk of loss to follow-up was 4.1% in Asia, 9.0% in Southern Africa, 14.0% in East Africa, and 21.8% in West Africa (P < 0.01). Age < 12 months, nonnucleoside reverse transcriptase inhibitor I-based ART regimen, World Health Organization stage 4 at ART start, ART initiation after 2005, attending a public sector or a nonurban clinic, having to pay for laboratory tests or antiretroviral drugs, larger cohort size, and living in East Africa or West Africa were significantly associated with higher loss to follow-up. CONCLUSIONS: Findings differed substantially across regions but raise overall concerns about delayed ART start, low access to free HIV services for children, and increased workload on program retention in lower-income countries. Universal free access to ART services and innovative approaches are urgently needed to improve pediatric outcomes at the program level.
