“…Estudos realizados por , Dalton (1976), Guimarães et al (1985) Kvalsvig & Shutte (1986) e Chandiwana & Woohouse (1991), Lima e Costa et al(1991) e Guerra (1992) analisaram áreas onde contatos com água naturais ocorriam por lazer e em atividades domésticas. Uma análise sobre o uso do paradigma de risco para a esquistossomose em sete áreas endêmicas sugere maior tendência de indivíduos de áreas rurais terem em torno de 70% dos contatos com águas naturais em atividades profissionais (agricultura e domésticas); nas áreas mais urbanizadas, esse percentual é observado por motivo de lazer (Coura-Filho, 1994).…”

This study identified the role of biological and social determinants in the transmission of schistosomiasis mansoni in Ravena, Minas Gerais, Brazil, in 1980. This data was used to characterize the clinical and epidemiological profiles of the endemic desease in the population, allowing for the determination of the efficacy of the potable water supply and the specific treatment of those infected with S. mansoni. The district contains three locations, Ravenopolis, Ravena and Lavapes, where the prevalence of the endemic disease was, 20.1%, 42.6% and 63.9%, respectively. The prevalence in the district was statistically higher in men. The age brackets that displayed differences by gender were 10-14 and 15-19 years. Severity of infection was statistically different among individuals within the 10-14 year bracket in ali three locations, and in the 15-19 year bracket among individuals from Ravenopolis and Ravena. The hepatointestinal form was associated with age, and individuals under 15 years of age presented risk of infection 8.85 times higher than adults. Multivariable analysis of the factors involved in transmission of the disease showed that Lavapes was independently associated with infection. In that area, poor sanitary conditions and the proximity of houses to streams infested with S. marsoni cercariae facilitated infection of neighborhood women while performing domestic activities, as well as men digging sand from the streams for construction. These results show the focal nature of transmission of the endemic requiring specific intervention for effective control of disease.

OBJECTIVE:Schistosomiasis remains a public health problem. This was a descriptive and retrospective study of 42 patients with a severe form of schistosomiasis who were admitted to the outpatient clinic of the Faculdade de Medicina da Universidade de São Paulo, São Paulo, in São Paulo, Brazil.METHODS:A data collection questionnaire was designed from the patient charts, and the following variables were evaluated: age, sex, place of birth, occupation, signs and symptoms of schistosomiasis, data from laboratory and imaging examinations, data regarding treatment outcomes, and the existence of comorbidities. Statistical analysis was carried out using Statistical Package for the Social Sciences 15.0 and Microsoft Excel 2003 software. The significance levels of the tests were fixed, accepting 5% type 1 error (α=0.05). Since this was a retrospective observational study, not all data were available for analysis.RESULTS:The mean age of the patients was 48.24 years; 57.1% were male. Statistically significant associations were observed between splenomegaly and thrombocytopenia (p=0.004) and between splenomegaly and leukopenia (p=0.046); however, only 4.5% of the patients had esophageal hemorrhage. Some patients received a specific treatment; of those, 42% took praziquantel, and 35.4% took oxamniquine. Nonspecific drug therapy was given as follows: 65% received propranolol, 90% omeprazole, and 43.6% aluminum hydroxide. The other treatments were as follows: 92.9% of patients underwent endoscopic treatment, 85% received sclerotherapy, and 62.5% used elastic bandages.CONCLUSION:This preliminary study presents a multidisciplinary outpatient follow-up associated with endoscopic and drug treatments that may be effective at preventing bleeding.

“…A análise de fatores de risco tem-se mostrado promissora em áreas endêmicas, tanto da região Nordeste (Barreto, 1987;1993), quanto da Sudeste (Lima e Costa et al, 1987, 1991Coura-Filho, 1994;Coura-Filho et al, 1995). No entanto, algumas dificuldades metodológicas dessa abordagem têm sido apontadas (Barreto, 1987;Ximenes & Araújo, 1995), o que limita seu uso na identificação dos fatores associados à infecção em muitas situações.…”

Failure of intensive chemotherapy to control schistosomiasis in a highly endemic area of Northeast Brazil led to the hypothesis that sociodemographic and/or behavioral variables could be involved in the persistent transmission. A univariate analysis of such variables in relation to infection by Schistosoma mansoni showed that water contact patterns for recreation and personal hygiene are important risk factors in the area. However, sociodemographic variables were not related to infection, probably because the local population lives under evenly precarious socioeconomic and sanitary conditions. We thus recommend that chemotherapy be combined with other measures like snail control, health education, and improved sanitation and water supply.
