Twenty one patients with seropositive rheumatoid arthritis and previously documented isolated haematuria were recalled at a median 7.7 years (range 3-12) after initial investigation. Eighteen subjects had previously undergone renal biopsy, which had shown mesangial glomerulonephritis in all but four cases. Renal function was found to have remained normal in all patients with previous mesangial changes despite the presence of persistent haematuria in most cases.
21例血清反应阳性类风湿性关节炎且先前记录有孤立性血尿的患者在初次检查后中位7.7年（范围3 - 12年）被召回。18名受试者先前接受了肾活检，除4例病例外，其余所有病例均显示为系膜增生性肾小球肾炎。尽管大多数病例存在持续性血尿，但先前有系膜改变的所有患者肾功能均保持正常。
