摘要

感染是多发性骨髓瘤(MM)发病和死亡的主要原因。虽然未确定意义的单克隆γ病(MGUS)显示感染风险增加,但阴燃型多发性骨髓瘤(SMM)的数据有限。我们使用来自iStopMM研究的数据,该研究筛选了75,422名年龄≥40岁的冰岛人的MM前体。诊断为SMM的个体按年龄和性别与无MGUS比较者(1:5)和患有MGUS的个体(1:1)匹配。感染结果来源于ICD-10诊断代码和抗菌药物处方的全国登记。Cox比例风险模型估计感染风险,调整免疫麻痹。188个SMM个体与188个MGUS个体相匹配,162个SMM个体与810个比较个体相匹配。SMM患者的感染(HR 1.36, 95% CI 1.07-1.73)和抗菌药物处方(HR 1.24, 95% CI 1.01-1.52)明显高于对照组。与MGUS相比,SMM个体也有更多的感染(HR 1.37, 95% CI 1.00-1.87)。调整免疫轻瘫减弱了这种关联,表明免疫轻瘫可能部分介导感染风险。与MGUS和没有MM前体的个体相比,首次筛选的SMM队列显示感染风险显着增加,这表明SMM的感染负担未被充分认识。

Increased risk of infections in smoldering multiple myeloma: results from the screened iStopMM study

Increased risk of infections in smoldering multiple myeloma: results from the screened iStopMM study

Infections are a major cause of morbidity and mortality in multiple myeloma (MM). While increased infection risk has been shown in monoclonal gammopathy of undetermined significance (MGUS), data are limited for smoldering multiple myeloma (SMM). We used data from the iStopMM study, which screened 75,422 Icelandic individuals aged ≥40 years for MM precursors. Individuals diagnosed with SMM were matched by age and sex with MGUS-free comparators (1:5 ratio) and with individuals with MGUS (1:1 ratio). Infection outcomes were derived from nationwide registries of ICD-10 diagnostic codes and antimicrobial prescriptions. Cox proportional hazards models estimated infection risk, adjusted for immunoparesis. 188 SMM individuals were matched to 188 MGUS individuals and 162 SMM individuals were matched to 810 comparators. Individuals with SMM had significantly more infections (HR 1.36, 95% CI 1.07–1.73) and antibacterial prescriptions (HR 1.24, 95% CI 1.01–1.52) than the comparators. Compared to MGUS, individuals with SMM also had more infections (HR 1.37, 95% CI 1.00–1.87). Adjusting for immunoparesis attenuated the associations, suggesting it may partially mediate infection risk. This first screened cohort of SMM shows a significantly increased infection risk, compared to both MGUS and to individuals without MM precursors, suggesting an underrecognized infection burden in SMM.
