In a previous trial the investigators found that the effect of steroids in IgA nephropathy diminish over time. The difference in renal survival is striking up till the third year, but then remains constant. A six-month course of steroid therapy may be not enough to ensure a stable remission. The investigators hypothesized that a more aggressive treatment may obtain long-term better results. The investigators conducted a randomised controlled trial to assess the utility of low-dose azathioprine added to steroids in adult IgAN patients.
In 1999, we published a multicenter, randomized, controlled trial, which compared a 6-month steroid course with supportive therapy in 86 patients with IgAN. After 5 years of follow-up, the risk of a 50% increase in plasma creatinine from baseline was significantly lower in the treated patients; proteinuria also decreased. However, the effect of steroids seemed to diminish over time. The difference in renal survival was particularly striking up till the third year, but then remained constant. We hypothesised that a six-month course of steroid therapy is not enough to ensure a stable remission, and a more aggressive treatment may be required to obtain long-term better results. At this regard, some studies of combined treatment with corticosteroids and azathioprine found that treatment was effective in preserving renal function and in reducing proteinuria. However, these studies did not clarify whether azathioprine added further benefit to steroids in the long term. We conducted a randomised controlled trial to assess the utility of low-dose azathioprine added to steroids in adult IgAN patients.
