摘要
免疫球蛋白A（immunoglobulin A, IgA）腎病是全世界原發性腎絲球腎炎最常見的原因。但由於疾病的異質性很高，所以不同研究所產生的結果並不同。近來的研究希望解決類固醇及其他治療的爭議，但追蹤時間都不夠長。若能更進一步確認類固醇可以改善長期腎功能，有助於幫助我們在權衡短期風險後使用類固醇。關於其他免疫抑制劑的使用並無足夠強的證據。期望能夠將風險及治療的關係更進一步釐清。

Immunoglobulin A (IgA) nephropathy is the most common cause of primary glomerulonephritis worldwide. However, due to the high heterogeneity of the disease, studies have variable results. Recent studies aim to resolve controversies of steroid and other treatment. However, the following periods are relative short. If we can further confirm that steroids can improve long-term renal outcome, it helps us to use steroid after weighing short-term risks. With regard to the use of other immunosuppressive agents, there is not enough strong evidence. It is hoped that the relationship between risk and treatment can be further clarified.
