Progression of the leprosy reaction and nerve damage: A prospective cohort study in children with leprosy from the Brazilian Amazon

A high proportion of children had progression of the leprosy reaction with worsening neural damage. The absence of warning signs of inflammation, such as pain and exacerbation of skin lesions, appears to contribute to the worse prognosis of reactions. Early diagnosis, systematic monitoring especially of neural function, beyond the educate caregivers to recognize the reactional episode early and to helping with children's self-care are very important measures to minimize the emergence or worsening of neural damage resulting from leprosy reactions.
