BACKGROUND
Organ transplantation (Tx) is a risk factor for Clostridium difficile infection (CDI). After intestinal transplantation (ITx), few data are available on the impact of this graft infection and the possible induction of rejection.
METHODS
We included retrospectively all children after ITx in our unit, with at least 1 year of graft survival. All samples positive for Clostridium difficile (CD) and its toxin were considered.
RESULTS
Among the 57 ITx recipients (60 Txs), 22 children (39%) developed culture-proven CDI, 12 after isolated small bowel Tx, 9 after liver-small bowel Tx, and 1 after multivisceral Tx. Twenty patients had diarrhea, 8 bloody stools, 4 fever, and 1 hypothermia. Nine were hospitalized for an average of 6.5 days (2-20) and 4 with severe dehydration. Nine (40%) had received antibiotics for an average of 19 days (7-60) before CDI. Two patients were asymptomatic. CDI was treated with metronidazole in 12 children, vancomycin in 6, and both in 3. Three children presented mild-to-severe rejections. Two patients presented concomitantly CDI and rejection. The third patient presented a rejection with severe complications 4 years after CDI. Recurrence of toxinogenic CD was observed in 9 children, in 7 associated with clinical symptoms. During the last follow-up, the stool number was the same as before CDI except for 1 patient with ongoing infection.
CONCLUSIONS
CDI is more prevalent in children after ITx compared with other organ Tx; it is most often symptomatic but mildly or moderately severe. Standard antibiotics efficiently control the symptoms. Induction of rejection is a rare event.
背景
器官移植(Tx)是艰难梭菌感染(CDI)的一个危险因素。在肠移植(ITx)后,关于这种移植物感染及其可能引发排斥反应的数据很少。
方法
我们回顾性地纳入了本单位所有至少有 1 年移植物存活的 ITx 后儿童。所有检测出艰难梭菌(CD)及其毒素阳性的样本均被纳入研究。
结果
在 57 例 ITx 受者(60 例 Tx)中,22 例(39%)发生了经培养证实的 CDI,12 例发生于孤立性小肠 Tx 后,9 例发生于肝-小肠 Tx 后,1 例发生于多脏器 Tx 后。20 例患者出现腹泻,8 例出现血便,4 例出现发热,1 例出现低体温。9 例住院,平均住院时间为 6.5 天(2-20 天),4 例伴有严重脱水。9 例(40%)在发生 CDI 前平均接受了 19 天(7-60 天)的抗生素治疗。2 例患者无症状。12 例患者接受甲硝唑治疗,6 例患者接受万古霉素治疗,3 例患者接受两者联合治疗。3 例患儿出现轻-重度排斥反应。2 例患儿同时出现 CDI 和排斥反应。第 3 例患儿在 CDI 后 4 年出现严重并发症的排斥反应。9 例患儿出现产毒 CD 复发,其中 7 例与临床症状相关。在最后一次随访时,除 1 例持续感染的患者外,其余患者的粪便次数与 CDI 前相同。
结论
与其他器官移植相比,儿童 ITx 后 CDI 更为常见;它通常是有症状的,但程度较轻或为中度。标准抗生素能有效控制症状。排斥反应的发生是一个罕见事件。
