当前数据并未强烈表明免疫介导性炎性疾病的存在可增加感染或重症风险。部分研究报道的风险升高，可能原因在于免疫介导性炎性疾病相关的合并症或患者正在采用的药物治疗（皮质类固醇、利妥昔单抗）。此类患者住院率升高与死亡率升高不具相关性。[253]Fagni F, Simon D, Tascilar K, et al.

炎性关节炎：证据并未显示炎性关节炎（例如类风湿性关节炎、脊柱关节炎）与感染风险或不良结局（例如住院、重症监护病房收治、需行机械通气或死亡）之间存在密切关联。然而，证据存在冲突。部分研究确实报道了不良结局风险升高，但研究存在局限性。[253]Fagni F, Simon D, Tascilar K, et al.

结缔组织病：多项研究表明，与普通人群和其他免疫介导性炎性疾病患者相比，结缔组织病（例如系统性红斑狼疮、干燥综合征、系统性硬化症、多发性肌炎和皮肌炎）患者感染风险有所升高。这可能是由于皮质类固醇在此类患者中的广泛使用。与结局相关的数据较为缺乏，证据存在冲突。[253]Fagni F, Simon D, Tascilar K, et al.
