COVID-19 and HIV/AIDS in a cohort study in Sao Paulo, Brazil: outcomes and disparities by race and schooling.

Studies describing characteristics and outcomes of COVID-19 among people living with HIV are currently limited, lacking detailed evaluation of the interplay among demographics, HIV-related variables, and comorbidities on COVID-19 outcomes. This retrospective cohort study describes mortality rates overall and according to demographic characteristics and explores predictors of admission to intensive care unit and death among 255 persons living with HIV with severe acute respiratory syndrome and confirmed SARS-CoV-2 infection in the State of Sao Paulo, Brazil. We found that the overall mortality rate was 4.1/1,000 person-days, with a case-fatality of 34%. Higher rates occurred among older adults, Black/Mixed skin color/race patients, and those with lower schooling. In a multivariable analysis adjusted for age, sex, CD4 count, viral load and number of comorbidities, skin color/race, and schooling remained significantly associated with higher mortality. Although tenofovir use was more frequent among survivors in the univariable analysis, we failed to find a statistically significant association between tenofovir use and survival in the multivariable analysis. Our findings suggest that social vulnerabilities related to both HIV and COVID-19 significantly impact the risk of death, overtaking traditional risk factors such as age, sex, CD4 count, and comorbidities.

Infecçäo por Clonorchis sinensis em imigrantes asiáticos no Brasil: tratamento com praziquantel / Clonorchis sinensis infections in Asian immigrants in Brazil: treatment with praziquantel

Estudaram-se quinze pacientes com infecçäo assintomática por Clonorchis sinensis, revelada através de exame parasitológico de fezes. Todos eram de origem asiática e procuraram o Laboratório Central do Instituto Adolfo Lutz para se submeterem a exames laboratoriais necessários a regularizaçäo de sua situaçäo, face a nova legislaçäo sobre imigrantes. Eram todos indivíduos adultos, seis pertencendo ao sexo feminino e nove ao masculino. Os quinze pacientes comn clonorquíase foram internados no Hospital das Clínicas da FMUSP e tratados com Praziquantel, na dosagem de 60 mg/Kg de peso corporal, dividida em duas tomadas. Foram realizados exames coprológicos quantitativos (método de Kato-Katz), antes do tratamento específico e no 15§, 30§ e 60§ dias após a terapêutica. Na última avaliaçäo (60§ dias após terapêutica), em nove pacientes (60,0%) näo se encontraram ovos do treamatódeo nas fezes e nos seis (40,0%), que continuavam eliminando ovos, notou-se reduçäo na quantidade eliminada (superior a 90% em cinco e a 30% no paciente restante). Os pacientes foram também submetidos a exames subsidiários, para avaliaçäo do estado geral e funçäo hepática, antes da administraçäo de Praziquantel e, posteriormente, no seguimento ambulatorial. A medicaçäo foi relativamente bem tolerada pelos pacientes, verificando-se a ocorrência de efeitos colaterais representados por náuseas e vômitos (dois casos), vertigens e tonturas (dois casos), epigastralgia (dois casos) e diarréia no 3§ dia após tratamento (um caso)
