countries have reported laboratory-confirmed cases of novel coronavirus disease (COVID-19). Although there are ongoing
clinical trials of repurposed and investigational antiviral and immune-based therapies, there are as yet no scientifically
proven, clinically effective pharmacological treatments for COVID-19. Among the repurposed drugs, the
commonly used antimalarials chloroquine (CQ) and hydroxychloroquine (HCQ) havebecome the focus of global scientific,
media, and political attention despite a lack of randomized clinical trials supporting their efficacy. Chloroquine has been
used worldwide for about 75 years and is listed by theWHOas an essential medicine to treat malaria. Hydroxychloroquine
is mainly used as a therapy for autoimmune diseases. However, the efficacy and safety of CQ/HCQ for the treatment of
COVID-19 remains to be defined. Indiscriminate promotion and widespread use of CQ/HCQ have led to extensive
shortages, self-treatment, and fatal overdoses. Shortages and increased market prices leave all countries vulnerable to
substandard and falsified medical products, and safety issues are especially concerning for Africa because of its
healthcare system limitations. Much needed in Africa is a cross-continental collaborative network for coordinated production,
distribution, and post-marketing surveillance aligned to low-cost distribution of any approved COVID-19 drug;
this would ideally be piggybacked on existing global aid efforts. Meanwhile, African countries should strongly consider
implementing prescription monitoring schemes to ensure that any off-label CQ/HCQ use is appropriate and beneficial
during this pandemic.Pre-prin
Profil clinique et immunologique des patients infectés par le VIH à l’initiation du traitement antirétroviral à Douala
The aim of this study was to describe the clinical and immunological profile of patients infected with HIV after initiation of antiretroviral therapy. Sociodemographic characteristics, clinical and immunological patients were recorded. Chi square test and Mann-Whitney were used to compare variables. The multivariate regression model identified risk factors. So that, 936 (56.2%) patients were in stages III and IV of the WHO and 65.2% at an advanced stage of the disease. Factors associated with initiation at an advanced stage, were male sex (p = 0.007) and time to diagnosis (p = 0.005). In 2/3 cases, treatment is started at an advanced stage of disease. It is therefore important to intensify awareness campaigns for early detection and encourage patients to ensure regular medical follow-up screening.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
