Pediatric community-acquired bloodstream infections (CA-BSIs) in sub Saharan African humanitarian contexts are rarely documented. Effective treatment of these infections is additionally complicated by increasing rates of antimicrobial resistance. We describe the findings from epidemiological and microbiological surveillance implemented in pediatric patients with suspected CA-BSIs presenting for care at a secondary hospital in the conflict affected area of Zamfara state, Nigeria. Any child (> 2 months of age) presenting to Anka General Hospital from November 2018 to August 2020 with clinical severe sepsis at admission had clinical and epidemiological information and a blood culture collected at admission. Bacterial isolates were tested for antibiotic susceptibility. We calculated frequencies of epidemiological, microbiological and clinical parameters. We explored risk factors for death amongst severe sepsis cases using univariable and multivariable Poisson regression, adjusting for time between admission and hospital exit. We included 234 severe sepsis patients with 195 blood culture results. There were 39 positive blood cultures. Of the bacterial isolates, 14 were Gram positive and 18 were Gram negative; 5 were resistant to empiric antibiotics: methicillin-resistant Staphylococcus aureus (MRSA; n = 2) and Extended Spectrum Beta-Lactamase positive enterobacterales (n = 3). We identified no significant association between sex, age-group, ward, CA-BSI, appropriate intravenous antibiotic, malaria positivity at admission, suspected focus of sepsis, clinical severity and death in the multivariable regression. There is an urgent need for access to good clinical microbiological services, including point of care methods, and awareness and practice around rational antibiotic in healthcare staff in humanitarian settings to reduce morbidity and mortality from sepsis in children.
在撒哈拉以南非洲的人道主义环境中,儿科社区获得性血流感染(CA-BSI)很少被记录。这些感染的有效治疗因抗菌药物耐药率的增加而变得更加复杂。我们描述了在尼日利亚赞法拉州冲突地区的一家二级医院,对疑似 CA-BSI 的儿科患者进行的流行病学和微生物学监测的结果。任何(>2 个月大)儿童,只要在入院时患有临床严重败血症,都将在 Anka 综合医院接受临床和流行病学信息以及入院时采集的血培养。对细菌分离株进行抗生素敏感性检测。我们计算了流行病学、微生物学和临床参数的频率。我们使用单变量和多变量泊松回归,调整入院和出院之间的时间,来探讨严重败血症病例死亡的危险因素。我们纳入了 234 例严重败血症患儿,其中 195 例有血培养结果。有 39 例血培养阳性。在细菌分离株中,14 株为革兰氏阳性菌,18 株为革兰氏阴性菌;5 株对抗生素经验治疗耐药:耐甲氧西林金黄色葡萄球菌(MRSA;n=2)和产超广谱β-内酰胺酶的肠杆菌科(n=3)。在多变量回归中,我们未发现性别、年龄组、病房、CA-BSI、适当的静脉内抗生素、入院时疟疾阳性、疑似败血症焦点、临床严重程度和死亡之间存在显著关联。在人道主义环境中,需要紧急获得良好的临床微生物学服务,包括即时检测方法,以及提高医护人员对抗生素的认识和合理使用,以降低儿童败血症的发病率和死亡率。
