Infection and graft-versus-host disease (GVHD) are among the most common complications after hematopoietic stem cell transplantation (HSCT). With well-known risk factors including allogeneic HSCT and GVHD, tuberculosis (TB) has a higher incidence and shorter survival rate in HSCT recipients than in the general population.
A 55-year-old Indonesian female with a history of latent TB was found to have acute myeloid leukemia 3 months after allogeneic HSCT. She presented with fever, abdominal pain, and predominant cholestatic-type liver function tests derangement. Computed tomography scans showed a relatively unremarkable liver. Liver biopsy specimens revealed multiple necrotizing granulomas with numerous acid-fast bacilli shown using Ziehl-Neelsen histochemical stain. No fungal organisms are detected by Grocott's methenamine silver and periodic acid-Schiff stains. There was also mild portal hepatitis with prominent bile duct injury and scattered apoptotic bodies, compatible with GVHD. In addition, the patient was also discovered to have cutaneous and intestinal TB as well as cutaneous and colonic GVHD during investigation. She was started on anti-TB treatment and adjusted immunosuppression scheme accordingly. Unfortunately, our patient died of spontaneous intracranial haemorrhage approximately 2 months after the diagnosis of post-transplantation TB and GVHD.
We report a case of concurrent hepatic TB and GVHD in an allogeneic HSCT recipient. Recognition of the dual pathology in the biopsy results aids proper treatment.
感染和移植物抗宿主病(GVHD)是造血干细胞移植(HSCT)后最常见的并发症。结核病(TB)是HSCT受者中一种发病率较高且生存率较低的疾病,其已知的危险因素包括异基因HSCT和GVHD,相较于普通人群,HSCT受者中结核病的发病率更高,生存率更低。
一名55岁的印度尼西亚女性,有潜伏性结核病史,在接受异基因HSCT后3个月被诊断为急性髓系白血病。她出现发热、腹痛,主要表现为胆汁淤积型肝功能检查紊乱。计算机断层扫描显示肝脏相对无明显异常。肝活检标本显示多个坏死性肉芽肿,采用齐-尼氏组织化学染色可见大量抗酸杆菌。格罗科特六胺银染色和过碘酸-希夫染色未检测到真菌。还存在轻度门静脉性肝炎,伴有明显的胆管损伤和散在的凋亡小体,符合GVHD表现。此外,在检查过程中还发现该患者患有皮肤和肠道结核以及皮肤和结肠GVHD。她开始接受抗结核治疗,并相应调整免疫抑制方案。不幸的是,在诊断移植后结核和GVHD约2个月后,我们的患者死于自发性颅内出血。
我们报告了一例异基因HSCT受者同时发生肝结核和GVHD的病例。认识活检结果中的双重病理有助于进行恰当治疗。
