Coccidioidomycosis is endemic to the Southwest United States and Mexico. In this case series we describe 3 cases, occurring in the Southwest United States, of patients with disseminated coccidioidomycosis infection in cirrhosis, all with a miliary pattern present on chest imaging.
This case series was performed conducting a review of patients' electronic health records and thorough review of the literature for coccidioidomycosis infection in patients with liver disease.
Three patients with different etiology of liver disease with Model for End-stage Liver Disease - Sodium (MELD-Na) scores >20 had chest imaging findings indicative of a miliary pattern on presentation. Each patient subsequently had extensive infectious disease workup that showed evidence of disseminated coccidioidomycosis. All 3 patients clinically worsened and eventually died.
This case series highlights the severity of disseminated coccidioidomycosis in patients with cirrhosis in an endemic area, as well as potential early clues such as miliary patterns on chest imaging. A review of the literature found a significant connection among potential mechanisms describing why patients with cirrhosis have such adverse outcomes in the setting of disseminated coccidioidomycosis, including cirrhosis-associated immune dysfunction and genetic defects in immune functioning.
球孢子菌病流行于美国西南部和墨西哥。在本病例系列中,我们描述了 3 例发生在美国西南部的肝硬化患者播散性球孢子菌病感染病例,所有患者的胸部影像学均表现为粟粒样模式。
通过对患者电子病历的回顾性研究,并对肝病患者的球孢子菌病感染进行了全面的文献复习,进行了本病例系列研究。
3 名患者因不同病因导致的肝功能失代偿(MELD-Na 评分>20),在就诊时出现了粟粒样模式的胸部影像学表现。每位患者随后进行了广泛的传染病检查,均显示有播散性球孢子菌病的证据。所有 3 名患者的临床状况均恶化,最终死亡。
本病例系列强调了在流行地区,肝硬化患者播散性球孢子菌病的严重程度,以及胸部影像学上出现粟粒样模式等潜在早期线索。文献复习发现,在描述为什么肝硬化患者在播散性球孢子菌病的情况下会出现如此不良结局的潜在机制中存在显著联系,包括与肝硬化相关的免疫功能障碍和免疫功能的遗传缺陷。
