IGA nephropathy – Are intravenous steroid pulses more effective than oral steroids in relapse prevention?
Introduction: It is recommended that IgA nephropathy (IgAN) is treated with steroids when the glomerular filtration rate (GFR) is >50 ml/min and proteinuria >1 g/day. Few studies have been performed comparing the two accepted steroid regimens (1 g/day methylprednisolone pulses for 3 consecutiv...

Introduction: It is recommended that IgA nephropathy (IgAN) is treated with steroids when the glomerular filtration rate (GFR) is >50 ml/min and proteinuria >1 g/day. Few studies have been performed comparing the two accepted steroid regimens (1 g/day methylprednisolone pulses for 3 consecutive days at the beginning of months 1, 3 and 5, followed by 0.5 mg/kg prednisolone on alternate days vs. 1 mg/kg/day oral prednisolone). The aim of this study was to compare these two steroid regimens in IgAN treatment. Methods: We selected 39 patients with biopsy-proven IgAN treated with steroids. Mean age at diagnosis was 37.5 years, 23 males (59%), baseline proteinuria (Uprot) was 2.1 g/day and median serum creatinine (SCr) was 1.5 mg/dl. The mean follow-up period was 56 months. Twenty-five patients (64%) were treated with methylprednisolone pulses and 14 (36%) with oral steroids. Results: Patients treated with steroid pulses presented lower relapse risk, defined as the reappearance of Uprot >1 g/day and an Uprot increase of more than 50% (incidence rate ratio of 0.18, 95% CI 0.02–0.5). The Kaplan–Meier analysis showed longer relapse-free period (p = 0.019). This result was confirmed in a multivariate analysis (p = 0.026). However, we did not find other differences between the two steroid regimens. Conclusions: In comparison to oral steroids, the intravenous pulse regimen was associated with a lower risk of relapse in IgAN, a known independent negative predictor of renal survival. No differences were found regarding the other renal outcomes. Resumen: Introducción: Se recomienda el tratamiento de la nefropatía por IgA (NIgA) con esteroides cuando el índice de filtración glomerular (IFG) > 50 ml/min y proteinuria > 1 g/día. Pocos han sido los estudios realizados comparando los 2 esquemas de esteroides aceptados (1 g/día de metilprednisolona en pulsos durante 3 días consecutivos en el principio de los meses 1, 3 y 5 seguido de 0,5 mg/kg en días alternos de prednisolona vs. 1 mg/kg/día de prednisolona oral). El objetivo de este estudio fue comparar estos 2 esquemas de esteroides en el tratamiento de la NIgA. Métodos: Fueron seleccionados 39 pacientes con NIgA demostrada por biopsia y tratados con esteroides. La edad media al diagnóstico fue de 37,5 años, 23 varones (59%), proteinuria basal (Uprot) 2,1 g/día y la creatinina sérica mediana (SCR) 1,5 mg/dl. El periodo medio de seguimiento fue de 56 meses. Veinticinco de los pacientes (64%) fueron tratados con pulsos de metilprednisolona y 14 (36%) con esteroides orales. Resultados: Los pacientes tratados con pulsos de esteroides presentan menor riesgo de recaída, definido como la reaparición de una Uprot > 1 g/día y aumento de más del 50% de la Uprot (razón de tasa de incidencia: 0,18; IC 95%: 0,02-0,5) y el Kaplan-Meier mostró período más largo libre de recaída (p = 0,019). Este resultado se confirmó en un análisis multivariante (p = 0,026). Sin embargo, no se encontraron otras diferencias entre los esquemas de esteroides. Conclusiones: En comparación con los esteroides orales, el esquema en pulsos intravenosos se relacionó con un menor riesgo de recaída en la NIgA, un conocido predictor negativo independiente de la supervivencia renal. No se encontraron diferencias en cuanto a los otros outcomes renales.
