Idiopathic CD4 lymphopenia (ICL) predisposes to opportunistic infections (OIs) but can often remain asymptomatic and does not have a strong association with monogenic mutations. Likewise, cryptococcal meningoencephalitis, the most common OI in ICL, is not strongly associated with monogenic mutations. In this study, we describe 2 patients with ICL plus an additional immune defect: one from an E57K genetic mutation in the nuclear factor-κβ essential modulator, and the other with acquired autoantibodies to granulocyte-macrophage colony-stimulating factor. Thus, these cases may exemplify a "multi-hit model" in patients with ICL who acquire OIs.
特发性CD4淋巴细胞减少症(ICL)易引发机会性感染(OIs),但通常可保持无症状,且与单基因变异并无紧密关联。同样,隐球菌性脑膜脑炎作为ICL中最常见的机会性感染,也与单基因变异没有很强的相关性。在本研究中,我们描述了2例患有ICL并伴有其他免疫缺陷的患者:1例存在核因子-κβ必需调节因子的E57K基因突变,另1例患有针对粒细胞-巨噬细胞集落刺激因子的自身抗体。因此,这些病例可能例证了ICL患者发生机会性感染的“多重打击模型”。
