RESUMO

Background: Glucose metabolic disorder (GMD) is closely related to inflammation among those living with HIV. However, there are extant studies regarding this phenomenon in sub-Saharan Africa (SSA) that bears the burden of HIV infection. Therefore, we assessed the associations between inflammation biomarkers and GMD on a cohort of HIV+ individuals in SSA. Methods: We conducted a cross sectional study at the largest (patient volume) HIV clinic in Tanzania from March to May 2018. Purposive sampling was used to identify 407 HIV+ patients on treatment. Data were collected using the World Health Organization (WHO) STEPwise approach for noncommunicable disease surveillance. Clinical and demographic variables were extracted from the medical chart. Fasting blood glucose and inflammatory markers [C-reactive protein (CRP), interleukin (IL)-6, IL-18, and soluble tumor necrosis factor receptor (sTNFR)-1, sTNFR-2] were measured. Bivariate and multivariate analysis was conducted to examine the association between the biomarkers and GMD. Results: GMD was present in 67.6% (n = 271). Among those with GMD, 44.5%, 38.4%, and 17.1% presented with impaired fasting glucose, impaired glucose tolerance, and diabetes mellitus, respectively. Being older (>55 years) and initiating smoking at an age >28 years was associated with GMD (P = 0.05). Engaging in moderate activity significantly reduced the risk of GMD (P = 0.04). Having a current CD4 count between 351 and 500 reduced the odds of GMD by 66.7% in comparison to clients with CD4 counts ≤350. Comparing the highest to the lowest quartile at the multivariate level, only CRP showed an independent significant association with GMD (adjusted odds ratio: 1.9; 95% confidence interval: 1.03-3.57). Despite a linear relationship, none of the other biomarkers showed a significant association with GMD. Conclusion: Our study shows that high CRP and low CD4 are important contributors to the prevalence of GMD. Even when controlling for confounding variables did not diminish the associations between GMD and CRP. These findings point to the importance of creating awareness, education, and screening for GMD in high-epidemic countries. More rigorous studies are needed to identify the manifestation of inflammation in HIV patients.

RESUMO

BACKGROUND: Due to concerns about the effects of the coronavirus disease 2019 (COVID-19 pandemic on health services, we examined its effects on human immunodeficiency virus (HIV) services in sub-Saharan Africa. METHODS: Quarterly data (Q1, 10/2019-12/2019; Q2, 1/2020-3/2020; Q3, 4/2020-6/2020; Q4, 7/2020-9/2020) from 1059 health facilities in 11 countries were analyzed and categorized by stringency of pandemic measures. We conducted a difference-in-differences assessment of HIV service changes from Q1-Q2 to Q3-Q4 by higher vs lower stringency. RESULTS: There was a 3.3% decrease in the number HIV tested from Q2 to Q3 (572 845 to 553 780), with the number testing HIV-positive declining by 4.9% from Q2 to Q3. From Q3 to Q4, the number tested increased by 10.6% (612 646), with an increase of 8.8% (23 457) in the number testing HIV-positive with similar yield (3.8%). New antiretroviral therapy (ART) initiations declined by 9.8% from Q2 to Q3 but increased in Q4 by 9.8%. Across all quarters, the number on ART increased (Q1, 419 028 to Q4, 476 010). The number receiving viral load (VL) testing in the prior 12 months increased (Q1, 255 290 to Q4, 312 869). No decrease was noted in VL suppression (Q1, 87.5% to Q4, 90.1%). HIV testing (P < .0001) and new ART initiations (P = .001) were inversely associated with stringency. CONCLUSIONS: After initial declines, rebound was brisk, with increases noted in the number HIV tested, newly initiated or currently on ART, VL testing, and VL suppression throughout the period, demonstrating HIV program resilience in the face of the COVID-19 crisis.

RESUMO

Triple elimination is an initiative supporting the elimination of mother-to-child transmission of three diseases - human immunodeficiency virus (HIV) infection, syphilis and hepatitis B. Significant progress towards triple elimination has been made in some regions, but progress has been slow in sub-Saharan Africa, the region with the highest burden of these diseases. The shared features of the three diseases, including their epidemiology, disease interactions and core interventions for tackling them, enable an integrated health-systems approach for elimination of mother-to-child transmission. Current barriers to triple elimination in sub-Saharan Africa include a lack of policies, strategies and resources to support the uptake of well established preventive and treatment interventions. While much can be achieved with existing tools, the development of new products and models of care, as well as a prioritized research agenda, are needed to accelerate progress on triple elimination in sub-Saharan Africa. In this paper we aim to show that health systems working together with communities in sub-Saharan Africa could deliver rapid and sustainable results towards the elimination of mother-to-child transmission of all three diseases. However, stronger political support, expansion of evidence-based interventions and better use of funding streams are needed to improve efficiency and build on the successes in prevention of mother-to-child transmission of HIV. Triple elimination is a strategic opportunity to reduce the morbidity and mortality from HIV infection, syphilis and hepatitis B for mothers and their infants within the context of universal health coverage.


La triple élimination est une initiative visant à soutenir l'éradication de la transmission mère-enfant de trois maladies ­ l'infection au virus de l'immunodéficience humaine (VIH), la syphilis et l'hépatite B. Bien que des avancées considérables aient été observées en ce sens dans certaines régions, les progrès demeurent lents en Afrique subsaharienne, pourtant durement touchée par ces maladies. Les caractéristiques communes aux trois affections, notamment leur épidémiologie, les interactions entre elles et les principales interventions nécessaires à leur prise en charge permettent aux systèmes de santé d'adopter une approche intégrée pour éviter la transmission mère-enfant. Plusieurs obstacles entravent actuellement la triple élimination en Afrique subsaharienne, parmi lesquels l'absence de politiques, de stratégies et de ressources pour garantir la disponibilité de traitements préventifs et curatifs bien établis. Les outils existants offrent déjà de nombreuses solutions; mais pour accélérer la progression de cette triple élimination en Afrique subsaharienne, il est indispensable de développer de nouveaux produits et modèles de soins, ainsi qu'un programme de recherche prioritaire. Dans le présent document, nous voulons montrer que si les systèmes de santé collaborent avec les communautés en Afrique subsaharienne, ils pourront obtenir des résultats rapides et durables en vue d'éradiquer la transmission mère-enfant des trois maladies susmentionnées. Néanmoins, une telle démarche implique un soutien politique massif, l'expansion des interventions fondées sur des données scientifiques, et une meilleure utilisation des sources de financement afin d'améliorer l'efficacité et de s'appuyer sur les réussites en matière de prévention de la transmission du VIH de la mère à l'enfant. La triple élimination représente une occasion stratégique de réduire la morbidité et la mortalité liées à l'infection au VIH, à la syphilis et à l'hépatite B, tant chez les mères que chez les nourrissons, dans un contexte de couverture maladie universelle.


La triple eliminación es una iniciativa que apoya la eliminación de la transmisión maternoinfantil de tres enfermedades: la infección por el virus de la inmunodeficiencia humana (VIH), la sífilis y la hepatitis B. En algunas regiones se han logrado avances significativos hacia la triple eliminación, pero los progresos se han desarrollado con mayor lentitud en el África subsahariana, la región con la mayor carga de estas enfermedades. Las características comunes de las tres enfermedades, como su epidemiología, las interacciones entre ellas y las intervenciones básicas para combatirlas, permiten un enfoque integrado de los sistemas de salud para la eliminación de la transmisión maternoinfantil. Los obstáculos actuales para la triple eliminación en el África subsahariana incluyen la falta de políticas, estrategias y recursos para apoyar la adopción de intervenciones preventivas y de tratamiento bien establecidas. Aunque se puede lograr mucho con las herramientas existentes, se necesita el desarrollo de nuevos productos y modelos de atención, así como una agenda de investigación prioritaria, para acelerar el progreso de la triple eliminación en el África subsahariana. En este documento pretendemos demostrar que los sistemas de salud que trabajan conjuntamente con las comunidades del África subsahariana podrían obtener resultados rápidos y sostenibles hacia la eliminación de la transmisión maternoinfantil de las tres enfermedades. Sin embargo, se necesita un mayor apoyo político, la ampliación de las intervenciones basadas en la evidencia y un mejor uso de los flujos de financiación para mejorar la eficiencia y aprovechar los éxitos en la prevención de la transmisión maternoinfantil del VIH. La triple eliminación es una oportunidad estratégica para reducir la morbilidad y la mortalidad de la infección por el VIH, la sífilis y la hepatitis B para las madres y sus hijos en el contexto de la cobertura sanitaria universal.

RESUMO

INTRODUCTION: Isoniazid preventive therapy (IPT) taken by People Living with HIV (PLHIV) protects against active tuberculosis (TB). Despite its recommendation, data is scarce on the uptake of IPT among PLHIV and factors associated with treatment outcomes. We aimed at determining the proportion of PLHIV initiated on IPT, assessed TB screening practices during and after IPT and IPT treatment outcomes. METHODS: A retrospective cohort study of a representative sample of PLHIV initiated on IPT between July 2015 and June 2018 in Kenya. For PLHIV initiated on IPT during the study period, we abstracted patient IPT uptake data from the National data warehouse. In contrast, we obtained information on socio-demographic, TB screening practices, IPT initiation, follow up, and outcomes from health facilities' patient record cards, IPT cards, and IPT registers. Further, we assessed baseline characteristics as potential correlates of developing active TB during and after treatment and IPT completion using multivariable logistic regression. RESULTS: From the data warehouse, 138,442 PLHIV were enrolled into ART during the study period and initiated 95,431 (68.9%) into IPT. We abstracted 4708 patients' files initiated on IPT, out of which 3891(82.6%) had IPT treatment outcomes documented, 4356(92.5%) had ever screened for TB at every clinic visit, and 4,243(90.1%) had documentation of TB screening on the IPT tool before IPT initiation. 3712(95.4%) of patients with documented IPT treatment outcomes completed their treatment. 42(0.89%) of the abstracted patients developed active TB,16(38.1%) during, and 26(61.9%) after completing IPT. Follow up for active TB at 6-month post-IPT completion was done for 2729(73.5%) of patients with IPT treatment outcomes. Sex, Viral load suppression, and clinic type were associated with TB development (p<0.05). Levels 4, 5, FBO, and private facilities and IPT prescription practices were associated with IPT completion (p<0.05). CONCLUSION: IPT initiation stands at two-thirds of the PLHIV, with a high completion rate. TB screening practices were better during IPT than after completion. Development of active TB during and after IPT emphasizes the need for a keen follow up.
