Bio-behavioral survey of syphilis in homeless men in Central Brazil: a cross-sectional study

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.

Syphilis and Co-Infections with HIV-1, HBV, and HCV among People Who Use Crack-Cocaine in Northern Brazil

The rates of syphilis and viral co-infections among people who use crack-cocaine (PWUCC) were assessed in this study. This cross-sectional study relied on biological and self-reported socio-behavioral data from a convenience sample of 990 PWUCC from twenty-six municipalities in the states of Amapá and Pará, northern Brazil. Blood samples were collected to assess the presence of Treponema pallidum using the Rapid Qualitative Test (RQT) and the Venereal Disease Research Laboratory (VDRL). Reactive samples by RQT were used to assess the presence of HBV, HCV, and HIV-1 using Enzyme Immunoassay (EIA) and Polymerase Chain Reaction (PCR). Logistic regression models were used to determine the association of variables assessed with syphilis. In total, 287 (29.0%) of the PWUCC sample had reactive results for syphilis. HBV (15.7%), HCV (5.9%), and HIV-1 (9.8%) were detected among PWUCC with syphilis. Young age, low monthly income and education level, long duration of crack-cocaine use, condomless sex, multiple sex partners, and exchange of sex for money/drugs were associated with syphilis. The present study provides unique insights on the epidemiological status of syphilis among PWUCC in northern Brazil, with multiple implications for improving urgent interventions for diagnosis, prevention, and treatment.

Prevalence of Chlamydia trachomatis and Neisseria gonorrhoeae in the homeless population of Medellín, Colombia: a cross-sectional study

OBJECTIVE

To determine the prevalence of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) in the homeless population in Medellín, Colombia, using molecular diagnostic methods. It also intended to develop a demographic profile, exploring associated factors and the dynamics of the social and sexual interactions of this community.

DESIGN

Cross-sectional study.

SETTING

Two homeless care centres in Medellín, Colombia.

PARTICIPANTS

Homeless individuals that assisted to the main homeless care centres of Medellín, Colombia from 2017 to 2019.

PRIMARY AND SECONDARY OUTCOME MEASURES

The prevalence of CT and NG in this population using qPCR detection, factors associated with CT and NG infection, and the sociodemographic profile of the community.

RESULTS

The prevalence of CT infection was 19.2%, while that of NG was 22.6%. Furthermore, being a female was significantly correlated to CT infection p<0.05 (adjusted OR, AOR 2.42, 95% CI 1.31 to 4.47). NG infection was significantly associated with factors such as: sexual intercourse while having a sexually transmitted infection p<0.05 (AOR 3.19, 95% CI 1.48 to 6.85), having more than 11 sexual partners in the last 6 months p=0.04 (AOR 2.91, 95% CI 1.04 to 8.09) and having daily intercourse p=0.05 (AOR 3.15, 95% CI 1.02 to 9.74).

CONCLUSIONS

The prevalence of CT and NG was higher than that reported in the general population. Additionally, females had a higher percentage of infection compared with males.

Application of the Frailty Framework among Vulnerable Populations to Hospitalization Outcomes of Individuals Experiencing Homelessness in Long Beach, California

BACKGROUND

Individuals experiencing homelessness have a high prevalence of infectious diseases that may result in hospitalization. However, low ability to navigate the healthcare system and lack of health insurance may mean that those who are experiencing homelessness may not receive the healthcare that they need.

OBJECTIVES

This study uses risk factors at baseline to predict hospitalization at follow-up. This paper also presents the associations between reporting homelessness and selected infectious diseases.

RESEARCH DESIGN

Longitudinal study of baseline and follow-up conducted August 2000 through July 2014.

SUBJECTS

4916 Not experiencing homelessness mean age 37.9 years, 29% female, and 2692 experiencing homelessness age 42.1 years, 29% female received services from a research/service center in a low-income, high-crime area of Long Beach, CA.

MEASURES

Risk Behavior Assessment, Risk Behavior Follow-up Assessment, laboratory testing for hepatitis A, hepatitis B, hepatitis C, syphilis, chlamydia, and gonorrhea.

RESULTS

Predictors of hospitalization at follow-up were ever use of crack cocaine, income from Social Security or disability, reporting homelessness, female, and those who identify as Black compared to White race/ethnicity.

CONCLUSIONS

Income from the safety net of Social Security or disability appears to provide the participant with experience that transfers to being able to obtain healthcare. A higher proportion of those experiencing homelessness, compared to those not experiencing homelessness, appear to be hospitalized at follow-up. Women, those who identified as Black, and those who used crack at baseline are more likely to be hospitalized at follow-up whether or not they were experiencing homelessness. We recommend coordination with substance abuse treatment programs for discharge planning for homeless patients. Our findings support use of the Frailty Framework when working with individuals experiencing both homelessness and hospitalization.
