Resumo
O presente trabalho comparou dois esquemas terapêuticos em pacientes com hanseníase multibacilar. O grupo 1, que recebeu o tratamento convencional (PQT-MB), foi denominado grupo controle. O grupo 2, denominado de grupo teste, recebeu a associação de rifampicina 600 mg, mais ofloxacina 400 mg, mais minociclina 100 mg (ROM), administrado sob supervisão, uma vez por mês. A duração total do tratamento nos dois grupos foi de dois anos. Na avaliação inicial foram realizados: exame clínico, baciloscópico e histológico. A baciloscopia e a biópsia foram repetidas no final do primeiro ano e novamente no final do segundo ano de tratamento. A avaliação clínica foi realizada mensalmente por ocasião da administração da dose supervisionada. No grupo 1 foram avaliados 14 pacientes. O índice baciloscópico (IB) antes do tratamento variou de 2 a 4,8. No grupo 2 foram estudados 12 pacientes. O IB antes do tratamento nesse grupo variou de 1,6 a 4,8. Ambos os grupos apresentavam lesões cutâneas que os caracterizavam como pertencentes ao pólo virchoviano. Histologicamente apresentavam quadro de hanseníase virchoviana ativa, exceto um paciente do grupo 2. Ao final do primeiro ano de tratamento estavam todos clinicamente melhorados, o índice baciloscópico diminuído e com quadro histológico em regressão. Essa tendência de melhora se mantinha e na avaliação do final do segundo ano todos estavam clinicamente, baciloscopicamente e histologicamente ainda melhores. A análise estatística dos parâmetros, baciloscópico e histológico, mostrou que não houve diferença estatisticamente significativa entre os grupos estudados, sendo, portanto os dois esquemas equivalentes. A ocorrência de reação tipo 2 (eritema nodoso hansênico - ENH) foi igual nos dois grupos. No grupo 1, todos apresentaram pigmentação cutânea devido a clofazimina...
The present study compared two therapeutic schemes in multibacillary leprosy patients. Group 1 was the control group that received the conventional (MDT-MB) treatment. Group 2 was the test group that received the association of rifampin 600 mg, ofloxacin 400 mg and minocyclin 100 mg (ROM), administrated once a month under supervision. Both groups were treated for two years. Initial evaluation of patients included: clinical examination, bacilloscopy and histology. Bacilloscopy and skin biopsy were repeated at the end of the first and second years of treatment. Clinical evaluation was performed monthly concomitant to administration of drugs. Fourteen patients were evaluated in group 1. Bacilloscopic index (BI) before treatment varied from 2 to 4.8. Twelve patients were evaluated in group 2. The BI before treatment in this group varied from 1.6 to 4.8. Both groups presented cutaneous lesions characteristic of the lepromatous type. The histological picture resembled active lepromatous leprosy, except for one patient of group 2. At the end of the first year of treatment all patients showed clinical improvement, the BI decreased and they presented regressive histological picture. This tendency to improvement was maintained and at the final evaluation in the second year all patient showed even better clinical, bacilloscopic and histological improvement. The statistical analysis of bacilloscopic and histological parameters showed there weren't significant differences between the groups studied, therefore, treatments were equally efficacious. Occurrence of type 2 (erythema leprosum nodosum ENL) reactional episodes was similar in both groups. In group 1 all patients presented skin pigmentation due to clofazimine. These results demonstrate that monthly administration of rifampin, plus ofloxacin plus minocyclin are as efficacious and secure as the conventional scheme...
