The Central African Republic, despite challenges related to the socio-political context, is committed to achieving the UNAIDS 90-90-90 targets and to the elimination of AIDS by 2030 advocated by the WHO. Objective: To analyze survival among HIV-positive adult patients on antiretroviral therapy from 2015 to 2020. Methods: This was a history-based cohort study of patients started on ART. The main variable was survival. The Kaplan-Meier method was used to describe the survival curve since inclusion in the cohort and a multivariate Cox model was used to investigate factors associated with mortality on ART. Results: A total of 145 naive patients started ART at the Outpatient Treatment Centre (OTC) in 2015. A female predominance was observed in our study with 78.08% of cases. The analysis of the patients’ fate at the time of point of treatment showed that 58.62% of them were still in active care and 13.10% died. The probability of survival at 5 years was 0.82 and mortality was significantly associated with very advanced disease (WHO stage IV) (p = 0.047) and anemia (p = 0.039). Conclusion: The majority of patients were still in care at the endpoint and mortality was significantly related to advanced disease and anemia. Early management of people living with HIV combined with better quality of care would improve their survival.展开更多

The long-term effects of the disease on the body’s organs are one of the leading causes of death in the world. To alleviate this global burden of DM, a number of studies have been conducted to lower blood glucose levels in patients. For genetic and ethical reasons, humans are far from being appropriate subjects in such investigations and the use of animal models has therefore been the way forward. Streptozotocin (STZ) is a glucosamine-nitrosourea compound that selectively destroys β-cells and has been widely used to induce Type I diabetes in several animal species. Recent literature has shown that a non-diabetic dose of STZ, combined with a high-fat diet (HFD), can mimic Type II diabetes. Yet, researchers seldom provide data to corroborate the high sensitivity of STZ on these animal models. In addition, there are few reports of potentially fatal effects of the use of STZ as a supplement in obese HFD animals when attempting to induce Type II diabetes. The present review article highlights the parameters that could be at the origin of the extreme sensitivity and vulnerability of obese animals to STZ.展开更多
