Tuberculosis among Brazilian indigenous individuals aged less than 15 years-old in State of Mato Grosso do Sul, Brazil

INTRODUCTION This study describes the epidemiological aspects of TB among Brazilian Native Indians aged less than 15 years-old in Mato Grosso do Sul, Brazil, between 2000 and 2006. METHODS A retrospective observational study based on secondary data collected from the health system of Brazilian indigenous peoples, Special Indigenous Sanitary District (DSEI), and National System of Notifiable Diseases (SINAN) databases. The variables analyzed were: frequency of TB according to sex, age, clinical presentation and outcome. The Fisher test and the incidence tendency curve were calculated (p<0.01). RESULTS TB prevalence was 20.4% (224/1,096). The incidence rate decreased 14% per year during the study period. TB was more prevalent among Brazilian indigenous individuals aged less than 5 years-old and among those aged less than one year-old. More than half of TB cases were male and the most common clinical presentation was pulmonary TB (92.9%). Cure was the most common outcome (91.1%), followed by abandoned treatment (3.6%) and death (2.2%). CONCLUSIONS The high cure rate, reduced mortality and the progressive decrease in TB incidence rate during the study period indicate the effectiveness of supervised treatment of the new TB control model implemented among Brazilian indigenous peoples on 2000.

Seroprevalence of hepatitis B virus infection and associated factors among prison inmates in state of Mato Grosso do Sul, Brazil

INTRODUCTION This study aimed to estimate the prevalence of HBV infection and associated factors among prison inmates in Campo Grande, MS. METHODS A total of 408 individuals were interviewed regarding sociodemographic characteristics, associated factors and HBV vaccination using a standardized questionnaire. Blood samples were collected from all participants and serological markers for HBV were detected by enzyme-linked immunosorbent assay. Hepatitis B surface antigen (HBsAg) and/or antibodies against hepatitis B core antigen (anti-HBc) positive samples were tested for HBV-DNA by polymerase chain reaction. RESULTS The overall prevalence of HBV infection was 17.9% (95%CI: 14.4-22.0). The HBsAg carrier rate was 0.5%; 56 (13.7%) individuals had been infected and developed natural immunity and 15 (3.7%) were positive for anti-HBc only. Ninety eight (24%) prisoners had only anti-HBs, suggesting that they had low vaccine coverage. An occult HBV infection rate of 0% was verified among anti-HBc-positive individuals. Multivariate analysis of associated factors showed that age > 35 years-old, low schooling level and illicit drug use are significantly associated with HBV infection. CONCLUSIONS Analysis of the data showed HBV infection prevalence similar or slightly lower than that reported in other of Brazilian prisons. Independent predictors of HBV infection in this population include older age, low schooling level and illicit drug use.

Vulnerabilidade de homens que fazem sexo com homens no contexto da AIDS

The number of AIDS cases in men who have sex with men (MSM) decreased in the initial years of the epidemic, but the percentage of cases in this group has remained unaltered in the last five years. This study, aimed to improve knowledge on the impact of AIDS in the daily lives of MSM, was conducted in Campo Grande, Mato Grosso do Sul State, Brazil, using a questionnaire and interviews. The results show that MSM perceive their vulnerability to HIV infection, referring to inconsistent condom use and multiple sex partners, given that 65% of homosexuals, 75% of bisexuals, and 33% of transvestites reported up to 5 partners in the previous month and emphasizing that 59% of the group reported more than 11 partners during the same period. The susceptibility of certain groups and the identification and understanding of their specificities pose a major challenge in any geographic context where such conditions are present.

Risk Factors for Death from Visceral Leishmaniasis in an Urban Area of Brazil.

Background Over the last three decades, the epidemiological profile of visceral leishmaniasis (VL) has changed with epidemics occurring in large urban centers of Brazil, an increase in HIV/AIDS co-infection, and a significant increase in mortality. The objective of this study was to identify the risk factors associated with death among adult patients with VL from an urban endemic area of Brazil. Methodology A prospective cohort study included 134 adult patients with VL admitted to the University Hospital of the Federal University of Mato Grosso do Sul between August 2011 and August 2013. Principal Findings Patients ranged from 18 to 93 years old, with a mean age of 43.6 (±15.7%). Of these patients, 36.6% were co-infected with HIV/AIDS, and the mortality rate was 21.6%. In a multivariate analysis, the risk factors associated with death were secondary bacterial infection (42.86, 5.05–363.85), relapse (12.17, 2.06–71.99), edema (7.74, 1.33–45.05) and HIV/AIDS co-infection (7.33, 1.22–43.98). Conclusions/Significance VL has a high mortality rate in adults from endemic urban areas, especially when coinciding with high rates of HIV/AIDS co-infection.

Prevalence and Incidence of HCV Infection among Prisoners in Central Brazil

The aim of this multicenter, cross sectional study was to assess the prevalence, incidence and associated risk factors among incarcerated populations from twelve Brazilian prisons. The total of 3,368 individuals from twelve prisons was randomly recruited between March 2013 and March 2014. Participants were interviewed, and provided blood samples which were tested for antibodies to Hepatitis C (HCV ab). One year after the first investigation, a cohort study was conducted with 1,656 inmates who participated the cross sectional study. Positive samples were tested for the presence of HCV RNA. Out of 3,368 inmates, 520 (15.4%) were females, and 2,848 (84.6%) were males. The overall prevalence of HCV was 2.4% (95% CI: 1.9 to 2.9), with 0.6% (95% CI: 0.4 to 0.8) in females, and 2.7% (95% CI: 2.1 to 3.3) in males (p<0.01). HCV RNA was detected in 51/80 (63.7%) samples. Among men prisoners, multivariate analysis of associated factors showed independent associations between HCV exposure and increasing age, inject drug use, length of incarceration, smoking hashish, sharing needle and syringe and HIV positivity. During the cohort study, 7/1,656 new cases of HCV infection were detected, and the incidence rate was 0.4/100 person-year. Once high frequency rates of specific HCV risk behaviors and new HCV infections have been identified inside prisons, effective interventions strategies such as screening, clinical evaluation and treatment to reduce the spread of HCV infection are essential.

A Cross-Sectional Survey of HIV Testing and Prevalence in Twelve Brazilian Correctional Facilities

Background Prior studies have reported higher HIV prevalence among prisoners than the general population in Brazil, but data have been derived from single prisons. The aim of this study was to evaluate HIV testing practices, prevalence and linkage to care among inmates in a network of 12 prisons. Methods We administered a questionnaire to a population-based sample of inmates from 12 prisons in Central-West Brazil and collected sera for HIV and syphilis testing from January to December 2013. We evaluated factors associated with HIV testing and infection using multivariable logistic regression models. Six months after HIV testing, we assessed whether each HIV-infected prisoner was engaged in clinical care and whether they had started antiretroviral therapy. Results We recruited 3,362 inmates, of whom 2,843 (85%) were men from 8 prisons, and 519 (15%) were women from 4 prisons. Forty-five percent of participants reported never having been tested for HIV previously. In multivariable analysis, the variables associated with previous HIV testing were lack of a stable partner (adjusted odds ratio [AOR]: 1.38; 95% CI: 1.18–1.60), completed more than four years of schooling (AOR 1.40; 95% CI: 1.20–1.64), history of previous incarceration (AOR: 1.68; 95% CI: 1.43–1.98), history of mental illness (AOR 1.52; 95% CI: 1.31–1.78) and previous surgery (AOR 1.31; 95% CI: 1.12–1.52). Fifty-four (1.6%) of all participants tested positive for HIV; this included 44 (1.54%) men and 10 (1.92%) women. Among male inmates, HIV infection was associated with homosexuality (AOR 6.20, 95% CI: 1.73–22.22), self-report of mental illness (AOR 2.18, 95% CI: 1.13–4.18), history of sexually transmitted infections (AOR 3.28, 95% CI: 1.64–6.56), and syphilis sero-positivity (AOR 2.54, 95% CI: 1.20–5.39). Among HIV-infected individuals, 34 (63%) were unaware of their HIV status; only 23 of these 34 (68%) newly diagnosed participants could be reached at six month follow-up, and 21 of 23 (91%) were engaged in HIV care. Conclusions HIV testing rates among prison inmates are low, and the majority of HIV-infected inmates were unaware of their HIV diagnosis. Incarceration can be an opportunity for diagnosis and treatment of HIV among vulnerable populations who have poor access to health services, but further work is needed on transitional HIV care for released inmates.

Prevalence and epidemiology of chronic hepatitis C among prisoners of Mato Grosso do Sul State, Brazil

In Mato Grosso do Sul state, Brazil, the number of prisoners has increased in the recent years and the control of hepatitis C virus (HCV) has become more complex. The aim of the present study was to estimate the prevalence and identify the genotypes of HCV in prisoners as well as the factors associated with this infectious disease. Thereby, 443 men and 243 women from prisons were interviewed and subjected to blood collection. Anti-HCV reactive samples were analyzed by RT-PCR and genotyped. The overall seroprevalence of HCV infection was 4.8% (95%CI: 3.4 to 6.8%). Furthermore, the prevalence was higher in: men, injecting drug users, tattooed persons, those who were more than 50 years old, individuals who have been arrested multiple times, people with previous history of sexually transmitted disease (STD), persons who received blood transfusions or those with HIV/AIDS. The prevalence of RNA HCV by PCR was 3.0% (95%CI: 1.7 to 4.2%). Moreover, the coinfection of HIV and HCV was 33.3%. In addition, genotype 1 was the most frequent (85%) followed by genotype 3 (15%). The screening strategy for HCV and other infectious diseases in inmates is important as it establishes an early diagnosis, opportunity for treatment and allows the breaking of the transmission chain.

Unifocal Bone Paracoccidioidomycosis, Brazil

We report a 47 year-old man from the State of Mato Grosso do Sul, Brazil, with unifocal tibial paracoccidioidomycosis. A radiograph showed an osteolytic lesion on the tibial middle third diaphysis. The diagnosis was confirmed by histopathologic analysis, and treatment with sulfamethoxazole and trimethoprim was started. After three months, the patient showed significant clinical improvement. Ten months after treatment, the patient showed lesion bone healing. This case describes the rare occurrence of an osteolytic lesion caused by endemic Paracoccidioides brasiliensis in Latin America.

Hepatitis B virus infection in a population exposed to occupational hazards: firefighters of a metropolitan region in central Brazil

INTRODUCTION By the nature of their activities, firefighters are exposed to a high risk of contracting hepatitis B virus (HBV) as most of the Fire Brigade occurrences in Campo Grande, State of Mato Grosso do Sul (MS), Brazil, are related to the rescue of victims of traffic accidents and the transportation of clinical and psychiatric emergencies. The aim of this study was to investigate the seroepidemiological profile of HBV infection in firefighters from the City of Campo Grande, central Brazil. METHODS The research involved 308 firefighters. After giving written consent, they were interviewed and blood was collected for the detection of HBsAg, anti-HBs and total anti-HBc of enzyme-linked immunosorbent assays (ELISA). RESULTS The participants had an average of 36.4 years of age (SD ± 6.5), being 89.9% male. Blood tests revealed 6.5% of seropositivity for hepatitis B (HB) infection (n=20), and 1% for HbsAg. Isolated anti-HBs markers, indicative of vaccine immunity, were found in 66.9% of the participants and 28.2% were susceptible to infection. With regard to risk factors for HB infection, multivariate regression analysis showed a statistically significant association with length of service; and prevalence was higher in individuals with over 20 years of service. CONCLUSIONS The prevalence of HB found among the firefighters was low and length of time in the profession was found to be a risk factor. Non-occupational risk factors did not influence the occurrence of HB infection in the population studied.
