Visceral leishmaniasis (VL) is one of the neglected diseases affecting the poorest segment of world populations. Sepsis is one of the predictors for death of patients with VL. This study aimed to assess the prevalence and factors associated with bacterial sepsis, causative agents, and their antimicrobial susceptibility patterns among patients with VL.
A cross-sectional study was conducted among parasitologically confirmed VL patients suspected of sepsis admitted to the University of Gondar Hospital, Northwest Ethiopia, from February 2012 to May 2012. Blood cultures and other clinical samples were collected and cultured following the standard procedures.
Among 83 sepsis suspected VL patients 16 (19.3%) had culture confirmed bacterial sepsis. The most frequently isolated organism was Staphylococcus aureus (68.8%; 11/16), including two methicillin-resistant isolates (MRSA). Patients with focal bacterial infection were more likely to have bacterial sepsis (P < 0.001).
The prevalence of culture confirmed bacterial sepsis was high, predominantly due to S. aureus. Concurrent focal bacterial infection was associated with bacterial sepsis, suggesting that focal infections could serve as sources for bacterial sepsis among VL patients. Careful clinical evaluation for focal infections and prompt initiation of empiric antibiotic treatment appears warranted in VL patients.
内脏利什曼病(VL)是影响世界最贫困人口的被忽视疾病之一。败血症是 VL 患者死亡的预测因素之一。本研究旨在评估 VL 患者中细菌性败血症的流行情况及其相关因素、病原体以及它们的药敏模式。
本研究为 2012 年 2 月至 5 月在埃塞俄比亚西北部贡德尔大学医院住院的疑似败血症的寄生虫学确诊 VL 患者进行了一项横断面研究。按照标准程序采集血培养和其他临床样本并进行培养。
在 83 例疑似败血症的 VL 患者中,有 16 例(19.3%)培养出细菌性败血症。最常分离到的病原体是金黄色葡萄球菌(68.8%,11/16),包括两株耐甲氧西林金黄色葡萄球菌(MRSA)。有局灶性细菌感染的患者更有可能发生细菌性败血症(P < 0.001)。
培养确诊的细菌性败血症的流行率较高,主要由金黄色葡萄球菌引起。并发局灶性细菌感染与细菌性败血症有关,这表明局灶性感染可能是 VL 患者发生细菌性败血症的来源。VL 患者需要仔细的临床评估和及时开始经验性抗生素治疗。
