Pan-American Guidelines for the treatment of SARS-CoV-2/COVID-19: a joint evidence-based guideline of the Brazilian Society of Infectious Diseases (SBI) and the Pan-American Association of Infectious Diseases (API).

BACKGROUND: Since the beginning of the COVID-19 pandemic, therapeutic options for treating COVID-19 have been investigated at different stages of clinical manifestations. Considering the particular impact of COVID-19 in the Americas, this document aims to present recommendations for the pharmacological treatment of COVID-19 specific to this population. METHODS: Fifteen experts, members of the Brazilian Society of Infectious Diseases (SBI) and the Pan-American Association of Infectious Diseases (API) make up the panel responsible for developing this guideline. Questions were formulated regarding prophylaxis and treatment of COVID-19 in outpatient and inpatient settings. The outcomes considered in decision-making were mortality, hospitalisation, need for mechanical ventilation, symptomatic COVID-19 episodes, and adverse events. In addition, a systematic review of randomised controlled trials was conducted. The quality of evidence assessment and guideline development process followed the GRADE system. RESULTS: Nine technologies were evaluated, and ten recommendations were made, including the use of tixagevimab + cilgavimab in the prophylaxis of COVID-19, tixagevimab + cilgavimab, molnupiravir, nirmatrelvir + ritonavir, and remdesivir in the treatment of outpatients, and remdesivir, baricitinib, and tocilizumab in the treatment of hospitalised patients with severe COVID-19. The use of hydroxychloroquine or chloroquine and ivermectin was discouraged. CONCLUSION: This guideline provides recommendations for treating patients in the Americas following the principles of evidence-based medicine. The recommendations present a set of drugs that have proven effective in the prophylaxis and treatment of COVID-19, emphasising the strong recommendation for the use of nirmatrelvir/ritonavir in outpatients as the lack of benefit from the use of hydroxychloroquine and ivermectin.

Antiretroviral therapy use in selected countries in Latin America during 2013-2017: results from the Latin American Workshop in HIV Study Group.

OBJECTIVE: To document antiretroviral use in Latin America during the last decade. METHODS: We collected indicators from 79 HIV health care centres in 14 Latin American Spanish-speaking countries for 2013-2017. Indicators were analysed by age, sex and other characteristics and weighted by the estimated people under care (PUC) population in each country. RESULTS: We gathered information on 116 299 PUC. One-third belonged to centres reporting a shortage of at least one antiretroviral therapy (ART) drug for >30 days during 2017. At end 2017, 95.1% of PUC were receiving ART. During 2013-2017, 45 329 people living with HIV were admitted to 39 centres. ART initiated during the first year after admission increased from 76.7% in 2013 to 83.8% in 2017. In 35 centres across the study period, 71.7% of PUC started ART with tenofovir disoproxil fumarate and lamivudine, and zidovudine use decreased. The third most common ART drug, EFV, reached 64.8%. Raltegravir and other alternatives increased annually to almost 10% of total use in 2017. CONCLUSIONS: Initial ART in Latin America is not based on the most recent scientific evidence and recommendations; use of drugs with higher efficacy and safety profiles and guarantee of ART availability continues to be a public health challenge.
