Leishmania chagasi infection in cats with dermatologic lesions from an endemic area of visceral leishmaniosis in Brazil

INTRODUCTION: Infection with Leishmania chagasi is the most common clinical presentation for visceral leishmaniaisis in endemic areas. The municipality of Raposa is an endemic area in State of Maranhão, Brazil, and have had registration cases of visceral leishmaniasis disease. For this reason, a cross- sectional study was conducted to evaluate the risk factors for infection with L. chagasi detected by Montenegro skin test. METHODS: The sample comprised 96% of the inhabitants of the villages of Maresia, Pantoja, and Marisol located in the municipality of Raposa, corresponding to 1,359 subjects. Data were collected using a questionnaire. Univariate and multivariate logistic regression models were applied to evaluate the association between the variables studied and infection of L. chagasi. RESULTS: The variables associated with infection upon nonadjusted analysis were a straw roof, mud walls, floors of beaten earth, presence of sand flies inside or outside of the dwelling, and bathing outdoors. Adjusted analysis showed that the presence of sand flies inside/outside the dwelling was a risk factor, and age younger than 10 years was a protective factor against asymptomatic infection. CONCLUSIONS: The results highlight the extent to which precarious living conditions of the population strengthen the epidemiological chain of visceral leishmaniasis.

The Relationship

Introduction: The knowledge of the relationship between Visceral Leishmaniosis and climatic aspects is already well established in the literature of other countries, but lack data of this relationship in Brazil. Objective: This study aimed to describe the seasonal distribution of hospitalizations for Visceral Leishmaniosis (VL) in a referral hospital for infectious diseases located in an endemic area of the semiarid in the Northeast of Brazil. Methods: The number of monthly hospitalizations between 2003 and 2012 was recorded retrospectively and was correlated with climate variables. Results: During this period 1,302 patients were hospitalized. We observed an inverse relationship with the monthly amount of precipitation (r = - 0.725; p = 0.008), the number of days per month with precipitation (r = - 0.683; p = 0.0144) and relative humidity (r = - 0.746; p = 0.005) when compared with the monthly number of hospitalizations due to VL. Inversely, there was a direct relationship with the maximum monthly mean temperature and the number of hospitalizations due to VL (r = 0.643; p = 0.024). Conclusions: The rainy season, characterized by more rainfall and higher humidity, was correlated with fewer hospitalizations for VL. Conversely, in months with higher temperatures the number of hospitalizations for VL was higher.
