We report a case of hypocomplementaemic urticarial vasculitis with an elevated serum rheumatoid factor level. Hypocomplementaemic urticarial vasculitis is an immune complex-mediated disease characterised by urticarial eruptions. High levels of rheumatoid factor may be associated with hypocomplementaemia due to the consumption of complement, because the rheumatoid factor can form immune complexes with immunoglobulin. It is necessary to pay attention to the amounts of complement in cases of urticarial eruptions with elevated rheumatoid factor level. The eruptions were relieved with a combination of prednisolone and colchicine.
我们报告一例低补体血症性荨麻疹性血管炎伴血清类风湿因子升高。低补体血症性荨麻疹性血管炎是一种免疫复合物介导的疾病，其特征为荨麻疹发作。类风湿因子水平升高可能与补体消耗导致的低补体血症有关，因为类风湿因子可以与免疫球蛋白形成免疫复合物。在类风湿因子水平升高的荨麻疹发作时，有必要注意补体的量。泼尼松龙和秋水仙碱联合治疗可缓解皮疹。
