primarily causes pneumonia in immunosuppressed individuals, particularly those living with advanced HIV/AIDS. Extrapulmonary dissemination is uncommon, with bone marrow involvement described in only a handful of cases globally. Bone marrow infection occurs in the setting of severe immunosuppression, poses diagnostic challenges, and carries a high mortality rate.
We describe the case of a 34-year-old man newly diagnosed with HIV/AIDS, presenting with severe immunosuppression and pneumonia. The patient initially improved with cotrimoxazole and corticosteroids, but was readmitted shortly after discharge with abdominal pain, diarrhea, and worsening pancytopenia. A bone marrow biopsy revealed cysts, confirming disseminated infection. Concomitant Kaposi sarcoma involving the skin and gastrointestinal tract was also diagnosed. Despite antimicrobial therapy, the patient's condition worsened, leading to multisystem organ failure and death two months later.
This case highlights a rare presentation of disseminated infection with bone marrow involvement in a patient with advanced HIV/AIDS. Although infrequent, this complication should be considered in individuals with pneumonia who develop persistent cytopenias and systemic symptoms. Diagnosis depends on histopathologic confirmation, which may lead to under-recognition. Early suspicion and individualized management are essential, though the optimal treatment approach for extrapulmonary infection remains undefined.
主要导致免疫抑制个体发生肺炎,尤其是晚期人类免疫缺陷病毒/获得性免疫综合征(HIV/AIDS)患者。肺外播散并不常见,全球仅有少数病例报道有骨髓受累情况。骨髓感染发生在严重免疫抑制的背景下,带来诊断挑战,且死亡率高。
我们描述了一名34岁新诊断为HIV/AIDS的男性病例,该患者出现严重免疫抑制和肺炎。患者最初使用复方新诺明和皮质类固醇后病情有所改善,但出院后不久因腹痛、腹泻和全血细胞减少加重再次入院。骨髓活检发现囊肿,证实为播散性感染。同时还诊断出皮肤和胃肠道伴有卡波西肉瘤。尽管进行了抗菌治疗,患者病情仍恶化,两个月后导致多系统器官衰竭并死亡。
本病例突出了晚期HIV/AIDS患者中罕见的播散性感染伴骨髓受累表现。虽然这种并发症不常见,但对于患有肺炎且出现持续性血细胞减少和全身症状的个体应考虑到这种情况。诊断依赖于组织病理学证实,这可能导致认识不足。早期怀疑和个体化管理至关重要,尽管肺外感染的最佳治疗方法仍不明确。
