Monoclonal gammopathy of uncertain significance (MGUS) may become symptomatic for autoimmune manifestations. We report on the prevalence and clinical course of immune thrombocytopenic purpura (ITP) observed in a consecutive series of 228 MGUS patients. At MGUS diagnosis, ITP was determined in 6/228 cases, accounting for a prevalence of 2630/100 000 [95% confidence interval (CI): 1210-5620]. One incidental ITP case occurred after 21 months of follow-up. After a follow-up of 681.3 patient-years, the crude incidence of ITP in MGUS was 146.8 per 100 000 patient-year (95% CI: 3.7-817.8). Overall, these observations point to an association between MGUS and ITP.
意义未明的单克隆丙种球蛋白病（MGUS）可能因自身免疫表现而出现症状。我们报告了在连续的228例MGUS患者系列中观察到的免疫性血小板减少性紫癜（ITP）的患病率和临床病程。在MGUS诊断时，228例中有6例被确定为ITP，患病率为2630/100000[95%置信区间（CI）：1210 - 5620]。1例偶然的ITP病例在随访21个月后出现。经过681.3患者年的随访，MGUS中ITP的粗发病率为每100000患者年146.8（95%CI：3.7 - 817.8）。总体而言，这些观察结果表明MGUS与ITP之间存在关联。
