ABSTRACT

OBJETIVO: Analisar a prevalência, gravidade e interferência funcional de transtornos do movimento (TM) secundários ao uso crônico de ciclosporina A (CsA). MÉTODO: Realizamos um estudo transversal em 60 pacientes (58.3% do sexo masculino) com idade média de 23.1 (3-75) anos, acompanhados pelo Serviço de Transplante de Medula Óssea do Hospital de Clínicas da Universidade Federal do Paraná, usando CsA por pelo menos seis meses. A avaliação incluiu dados clínicos, interferência funcional de possíveis sintomas e exame neurológico incluindo observação e graduação de TM. RESULTADOS: Oito (13.3%) entrevistados relataram tremor no momento da entrevista e 29 (48.3%) em alguma fase do tratamento. O exame neurológico identificou 14 (23.3%) pacientes com TM: 13 (21.6%) tremor de ação simétrico de membros superiores e em 1 (1.7%) parkinsonismo (rigidez e bradicinesia). Nenhum outro TM foi detectado. Os escores médios indicaram quadros leves em todos os casos. Os sintomas foram também considerados subjetivamente leves e sem interferência funcional. CONCLUSÃO: Quase um quarto dos pacientes usando CsA cronicamente apresenta TM, quase sempre tremor de ação leve e transitório, interferindo pouco funcionalmente, não requerendo intervenção na maioria dos casos.

ABSTRACT

Reversible posterior leucoencephalopathy syndrome (RPLS) has previously been described in patients who have renal insufficiency, eclampsia, hypertensive encephalopathy and patients receiving immunosuppressive therapy. The mechanism by which immunosuppressive agents can cause this syndrome is not clear, but it is probably related with cytotoxic effects of these agents on the vascular endothelium. We report eight patients who received cyclosporine A (CSA) after allogeneic bone marrow transplantation or as treatment for severe aplastic anemia (SSA) who developed posterior leucoencephalopathy. The most common signs and symptoms were seizures and headache. Neurological dysfunction occurred preceded by or concomitant with high blood pressure and some degree of acute renal failure in six patients. Computerized tomography studies showed low-density white matter lesions involving the posterior areas of cerebral hemispheres. Symptoms and neuroimaging abnormalities were reversible and improvement occurred in all patients when given lower doses of CSA or when the drug was withdrawn. RPLS may be considered an expression of CSA neurotoxicity
