Tratamento da cisticercose subcutânea co praziquantel: um novo agente cestoidicida Treatment of dermal cysticercosis with praziquantel: a new cestocidal agent

Abstract

Twenty adult patients presenting dermal cysticercosis without cerebral or ocular involvement were treated with praziquantel. The first eleven cases received 60 mg/kg/day and the last nine cases 30 mg/kg/day. In both groups the daily dose was split into three oral intakes 4 to 6 hours apart and the drug administration lasted for 6 consecutive days. The latter group of patients also got dexamethasone, 3 mg daily, from one day before until four days after the treatment period with praziquantel. The drug proved to be 100% efficacious as demonstrated histopathologically by the death of the cysticerci of Taenia solium (Cysticercus cellulosae) in serial biopsies taken from the 2nd week on after the end of treatment, as well as clinically by the steady disappearence of the dermal nodules during the 6 months following the therapy. Tolerance of praziquantel was good as the incidence and severity of side-effects were not relevant. The drug safety was confirmed through laboratory tests which failed to detect any abnormal findings related to the hematopoietic, liver and kidney functions.
