ABSTRACT
Objetivo: Analizar la efectividad y tolerancia a corto plazo de la terapia con rituximab (RTX) en pacientes con lupus eritematoso sistémico (LES) y diferentes manifestaciones clínicas. Pacientes y métodos: Se estudió a un total de 13 pacientes. El RTX fue indicado en 6 ocasiones para el tratamiento de nefritis refractaria, en 5 para el tratamiento de trombocitopenia grave, en 1 para el tratamiento de aplasia medular y en 1 para el tratamiento de vasculitis peritoneal asociada a nefritis. Los 13 pacientes fueron tratados con 4 dosis semanales de 375 mg/m2 de RTX. El tiempo medio de seguimiento fue 12 ± 8,5 meses. Nueve pacientes experimentaron una respuesta favorable; 3 con nefropatía, 5 con trombocitopenia y 1 con vasculitis peritoneal y nefritis. El SLEDAI medio pasó de 11 a 6,5. Dos pacientes con trombocitopenia presentaron recidivas; y la respuesta al retratamiento fue buena. Conclusiones: El presente estudio demuestra que RTX es un fármaco efectivo y seguro, a corto plazo, en el tratamiento de diferentes manifestaciones clínicas asociadas al LES(AU)
Objective: To assess the short-term effectiveness and tolerance of rituximab in patients with systemic lupus erythematous and distinct clinical manifestations. Patients and methods: Thirteen patients were studied. Rituximab (RTX) was indicated for refractory nephritis in 6 patients, severe thrombocytopenia in 5, aplastic anemia in 1 and peritoneal vasculitis associated with nephritis in 1. All patients received 4 weekly doses of 375 mg/m2 of RTX. The mean length of follow-up was 12 ± 8.5 months. Response was favorable in 9 patients: 3 with nephritis, 5 with thrombocytopenia and 1 with peritoneal vasculitis and nephritis. The mean SLE disease activity index decreased from 11 to 6.5 points. Thrombocytopenia recurred in 2 patients, who responded well to retreatment. Conclusions: The present study demonstrates that RTX is safe and effective as short-term therapy for distinct clinical manifestations associated with SLE(AU)

PATIENTS AND METHODS: Thirteen patients were studied. Rituximab (RTX) was indicated for refractory nephritis in 6 patients, severe thrombocytopenia in 5, aplastic anemia in 1 and peritoneal vasculitis associated with nephritis in 1. All patients received 4 weekly doses of 375 mg/m(2) of RTX. The mean length of follow-up was 12±8.5 months. Response was favorable in 9 patients: 3 with nephritis, 5 with thrombocytopenia and 1 with peritoneal vasculitis and nephritis. The mean SLE disease activity index decreased from 11 to 6.5 points.
