We describe four patients with seropositive rheumatoid arthritis who developed proteinuria and microscopic haematuria. Renal biopsy demonstrated a mesangial proliferative glomerulonephritis with mesangial deposits of IgA. These data suggest a possible causal relationship between rheumatoid arthritis and IgA nephropathy.
我们描述了4例血清学阳性类风湿关节炎患者，他们出现了蛋白尿和镜下血尿。肾活检显示为系膜增生性肾小球肾炎，伴有IgA系膜沉积。这些数据提示类风湿关节炎与IgA肾病之间可能存在因果关系。
