Abstract
Introduction: leprosy reactions have the potential to cause disabilities. Many individuals experience recurrent episodes of reaction during treatment. Objective: to identify clinical and histopathological characteristics that differentiate patients with leprosy reactions from those without leprosy reactions. Method: this is a prospective study conducted from July 2015 to December 2016, evaluating individuals newly diagnosed with leprosy and treated at the dermatology service of the Clementino Fraga Hospital Complex in João Pessoa, Paraíba, Brazil. The subjects were classified according to the Ridley-Jopling/Madrid criteria and operational classification. They underwent a histopathological examination at the time of diagnosis and 12 months later, and were reassessed 6 and 12 months after the diagnosis. Results: the group without a reaction had a greater number of lesions with clear delimitation. Individuals with a reaction showed a predominance of multibacillary forms. The group with a reaction had a greater number of individuals with a degree of disability greater than zero. A positive correlation was observed between the bacilloscopic index and the occurrence of reactions. Discussion: the lack of clear boundaries around the lesions may be linked to the onset of a leprosy reaction. The higher incidence of reactions in individuals with some degree of physical disability indicates a correlation between disability and multibacillary disease. Additionally, a positive correlation was found between the bacilloscopic index of the biopsy and the occurrence of reactions. Conclusion: the high incidence of severe reactions underscores the need for ongoing studies on leprosy and the identification of early clinical characteristics that suggest leprosy reactions.
