A patient known to have renal insufficiency was admitted to the hospital with fever and pancytopenia after returning from a trip to Mali. Pancytopenia was not caused by a tropical infection but was a side effect of atovaquone/proguanil used as malaria chemoprophylaxis. High and prolonged detectable proguanil serum levels can result in bone marrow suppression in patients with renal insufficiency. This should be taken into account in a returning traveller with fever and pancytopenia.
一位已知肾功能不全的患者,从马里旅行回来后出现发热和全血细胞减少,收入院治疗。全血细胞减少不是热带感染引起的,而是阿托伐醌/磺胺多辛作为疟疾化学预防用药的副作用。肾功能不全患者,高浓度且长时间可检测到的磺胺多辛血清水平可导致骨髓抑制。对于发热和全血细胞减少的旅行者,应考虑到这一点。
