摘要

背景:最近,越来越多的报道显示抗干扰素γ (IFN-γ)自身抗体(aiga)与几种严重的播散性感染密切相关。然而,aiga合并中枢神经系统(CNS)感染的报道很少。在这里,我们描述了3例aigas阳性的成年人,他们患有持续或复发的弥散性感染,这些感染由马尔尼菲塔芳香菌(TM)、非结核分枝杆菌(NTM)、结核分枝杆菌(TB)或其他病原体引起,并伴有中枢神经系统感染。此外,我们对aigas阳性的中枢神经系统感染患者进行了全面的文献综述。病例介绍:我们报告了3例hiv阴性的复发性播散性感染,包括中枢神经系统,并测量了aiga。所有患者均无基础疾病史或免疫抑制史,表现为发热、咳嗽和头痛。他们的HIV抗体呈阴性,而aiga呈阳性。根据脑脊液(CSF)检查和下一代测序(NGS)诊断为中枢神经系统感染。所有患者均根据不同病原菌接受抗感染治疗,病情稳定,无复发。结论:在没有已知免疫缺陷的严重和复发性多器官感染的成年人中,应考虑成人发病的免疫缺陷(AOID)与aiga相关。在aigas阳性患者中,血脑屏障(BBB)可能被破坏,导致对中枢神经系统感染的易感性。

Central nervous system infections in patients with anti-interferon-γ autoantibodies: case series and review of the literature.

Central nervous system infections in patients with anti-interferon-γ autoantibodies: case series and review of the literature.

Central nervous system infections in patients with anti-interferon-γ autoantibodies: case series and review of the literature.

Background: Recently, increased reports reveal that anti-interferon-gamma (IFN-γ) autoantibodies (AIGAs) are strongly associated with several severe disseminated infections. However, reports on AIGAs with central nervous system (CNS) infections are rare. Here, we described three AIGAs-positive adults who had persistent or recurrent disseminated infections caused by Talaromyces marneffei (TM), nontuberculous mycobacteria (NTM), mycobacterium tuberculosis (TB), or other pathogens, accompanied with CNS infections. In addition, we conducted a thorough literature review of AIGAs-positive patients with CNS infections.

Case presentation: We report three HIV-negative cases of recurrent disseminated infections including CNS, and AIGAs were measured. All patients had no history of underlying diseases or immunosuppression and presented with fever, cough, and headache. They were negative for HIV antibodies but positive for AIGAs. The patients were diagnosed with CNS infections based on cerebrospinal fluid (CSF) examination and next-generation sequencing (NGS). All patients received anti-infective treatment according to different pathogens, and their condition remained stable without recurrence.

Conclusions: In adults with severe and recurrent infections of multiple organs without known immunodeficiency, adult-onset immunodeficiency (AOID) associated with AIGAs should be considered. In AIGAs-positive patients, the blood-brain barrier (BBB) may be disrupted, leading to susceptibility to CNS infections.
