Human immunodeficiency virus infection and syphilis among homeless people in a large city of Central-Western Brazil: prevalence, risk factors, human immunodeficiency virus-1 genetic diversity, and drug resistance mutations

Seroprevalence of Treponema pallidum infection in Brazilian indigenous people: a cross-sectional study

Indigenous communities in Brazil have a complex epidemiological profile, which increases their chances of contracting sexually transmitted diseases. However, limited data is available on Treponema pallidum infections in this population. We investigated the seroprevalence and risk factors associated with T. pallidum infection in an indigenous population of Dourados, Mato Grosso do Sul. Blood samples were collected from September 2017 to March 2020, and the participants were interviewed to obtain comprehensive data on demography and sexual behavior. Serological tests were performed to detect T. pallidum infection. Besides conducting descriptive analysis, we performed Chi-squared tests and determined the bivariate odds ratio. The data were also analyzed using logistic regression. Among the 2190 invited individuals, 1927 (88%) were included in this study. The seroprevalence of T. pallidum infection was 2.91%. The results of a multivariate analysis showed that individuals who were 30-39 years old, with up to 4 years of school education, living in households without piped water, with a history of genital lesions, multiple sexual partners, and having a history of STIs had the highest seroprevalence of T. pallidum. This study showed that behavioral, social, and economic factors play an important role in the transmission of T. pallidum within the indigenous population. Thus, targeted intervention, including imparting education in the native language, mass testing initiatives, and implementing public policies to improve socioeconomic indicators, is needed to reduce the cases of syphilis in this community.

Saúde dos indivíduos em situação de rua

Introdução: A população em situação de rua é vulnerabilizada por diversos fatores que determinam ou condicionam sua saúde e ocasionam aumento dos índices de comorbidades clínicas, entre elas as doenças mentais, crônicas e infectocontagiosas. A marginalização dos indivíduos que se encontram em situação de rua abre uma lacuna na assistência em saúde que, por vezes, é suprida por organizações sem fins lucrativos que exercem um papel social elementar. Objetivo: Mapear o perfil clínico da população em situação de rua de Curitiba (PR) atendida por iniciativa voluntária no período de um ano. Métodos: Trata-se de um estudo observacional descritivo de base documental realizado com fichas clínicas dos 509 pacientes maiores de 18 anos e que tiveram seu primeiro atendimento médico realizado pela Associação Médicos do Mundo, filial Curitiba (PR), no ano de 2019. Resultados: Indivíduos do sexo masculino, de etnia branca, faixa etária entre 36 e 45 anos, que cursaram o ensino fundamental e que se encontravam havia menos de um ano em situação de rua foram as condições sociodemográficas predominantes. As principais queixas motivadoras da procura pelo atendimento foram dor (45,19%), lesões cutâneas (15,71%) e queixas oftalmológicas (6,68%). Parte dos indivíduos mostrou acometimento crônico por hipertensão arterial sistêmica (9,03%), HIV/AIDS (3,53%) e diabetes mellitus (3,53%). Também foi identificada quantidade significativa de relatos de histórico de traumas físicos (59%). Encontrou-se correlação estatística entre hipertensão e medicamentos de uso contínuo (p=0,001). Menos que 10% dos indivíduos procuraram atendimento médico por queixas de saúde mental. Das mulheres que fizerem parte do estudo, 70% relataram fazer uso de substâncias e aproximadamente metade delas, uso regular de medicamentos. Já o uso de anticoncepcionais foi relatado por uma minoria delas (18,57%). Conclusões: As queixas de dor, as lesões cutâneas e as demandas oftalmológicas foram os principais motivadores da procura por ajuda médica pela população em situação de rua, além da prevalência de hipertensão arterial sistêmica como doença crônica. Os achados podem auxiliar e direcionar ações em saúde voltadas para essa população marginalizada.

Health status and health behaviour of the Hungarian homeless people

BACKGROUND

Homelessness has risen recently in Europe, but there is lack of comprehensive health data on this population. Our aim was to characterize the health of the Hungarian homeless population.

METHODS

We performed a health survey with 453 homeless individuals. The results were compared to the age and sex standardized data of the general Hungarian population and its lowest income quintile from the European Health Interview Survey 2014. The differences by the ETHOS classification within the homeless population were also studied.

RESULTS

Significantly fewer homeless people reported good health status than in the general population or in its lowest income quintile (p< 0.001). Of the participants 70% had at least one chronic disease, only 41% of them visited a GP and 35% took medication in the previous 12 months. While 59% of the lowest income quintile and 50% of the general population had at least one chronic disease, almost all of them visited a physician and took medication. The highest prevalence of morbidity (80%) and multimorbidity (46%) was reported in the houseless group. The majority of the homeless people were current smokers, the prevalence was much higher than in the two reference populations (p< 0.001). The prevalence of heavy drinkers was the highest among the roofless participants (40%).

CONCLUSIONS

Homeless people have much poorer health and they utilize health services less than the most disadvantaged quintile of the general population. There is a clear social gradient within the homeless population, as well, which calls for integrated approaches for specific interventions to improve their health.
