Bloodstream infection (sepsis) represents a systemic inflammatory response to systemic infection by bacteria, fungi, and viruses that can lead to severe complications and death. The therapeutic management to reduce mortality and morbidity associated with sepsis is difficult due partly to (re)emergence of antimicrobial resistance. The choice of empirical antibiotics, therefore, partly depends on the pattern of local/national antibiotic resistance. This systematic review and meta-analysis aimed to determine the prevalence of bacteremia among pediatric patients with suspected bloodstream infections in Ethiopia, based on culture-confirmed bacterial isolates.
A comprehensive search of PubMed, Google Scholar, and grey literature was conducted for studies published between January 2010 and April 2024 on bacterial bloodstream infections and antimicrobial resistance. Laboratory-based observational studies reporting bacterial isolates and resistance patterns were included. Data from 23 eligible studies were extracted independently, organized in Excel, and analyzed using Stata version 14. Pooled prevalence estimates were calculated using a random-effects model. Heterogeneity was assessed via the I² statistic, publication bias through funnel plots and Egger's test, and sensitivity analysis evaluated the influence of individual studies.
The pooled prevalence of bacterial bloodstream infections (BSIs) among pediatric patients in Ethiopia was 30.66% (95% CI: 27.18-34.15), underscoring a serious public health concern. The most frequently isolated pathogens were Klebsiella species (30.6%), coagulase-negative staphylococci (CoNS), and Staphylococcus aureus, with Gram-negative bacteria comprising 56.65% of isolates. The overall pooled prevalence of multidrug resistance (MDR) was alarmingly high at 80.54%, with 100% resistance observed in both Klebsiella and Acinetobacter species. Subgroup analyses revealed MDR rates of 81.9% in general wards, 78.35% in NICUs, 82.07% among children, and 78.86% among neonates. Regionally, MDR prevalence ranged from 76.7% in Tigray to 91.3% in Addis Ababa, Amhara, and Oromia-highlighting a critical challenge for sepsis treatment and antimicrobial stewardship in Ethiopian pediatric care settings.
The findings underscore the urgent need for robust antimicrobial stewardship and enhanced surveillance to combat the growing threat of AMR in pediatric BSIs in Ethiopia. Strengthening routine antimicrobial susceptibility testing, improving healthcare infrastructure, and raising public awareness on responsible antibiotic use are critical. Targeted interventions are essential to guide effective treatment, prevent therapeutic failure, and reduce sepsis-related mortality.
血流感染(败血症)是机体对细菌、真菌和病毒引起的全身感染产生的全身性炎症反应,可导致严重并发症和死亡。由于抗菌药物耐药性的(再)出现,降低败血症相关死亡率和发病率的治疗管理具有一定难度。因此,经验性抗生素的选择部分取决于当地/全国的抗生素耐药模式。本系统评价和荟萃分析旨在根据培养确诊的细菌分离株,确定埃塞俄比亚疑似血流感染的儿科患者中菌血症的患病率。
对PubMed、谷歌学术和灰色文献进行全面检索,查找2010年1月至2024年4月期间发表的关于细菌性血流感染和抗菌药物耐药性的研究。纳入报告细菌分离株和耐药模式的基于实验室的观察性研究。独立提取23项符合条件的研究的数据,整理到Excel中,并使用Stata 14版进行分析。采用随机效应模型计算合并患病率估计值。通过I²统计量评估异质性,通过漏斗图和Egger检验评估发表偏倚,敏感性分析评估个别研究的影响。
埃塞俄比亚儿科患者中细菌性血流感染(BSIs)的合并患病率为30.66%(95%CI:27.18 - 34.15),凸显了一个严重的公共卫生问题。最常分离出的病原体是克雷伯菌属(30.6%)、凝固酶阴性葡萄球菌(CoNS)和金黄色葡萄球菌,革兰氏阴性菌占分离株的56.65%。多重耐药(MDR)的总体合并患病率高得惊人,为80.54%,在克雷伯菌属和不动杆菌属中均观察到100%的耐药率。亚组分析显示,普通病房的MDR率为81.9%,新生儿重症监护病房为78.35%,儿童为82.07%,新生儿为78.86%。在地区层面,MDR患病率从提格雷的76.7%到亚的斯亚贝巴、阿姆哈拉和奥罗米亚的91.3%不等,这突出了埃塞俄比亚儿科护理环境中败血症治疗和抗菌药物管理面临的严峻挑战。
研究结果强调了迫切需要强有力的抗菌药物管理和加强监测,以应对埃塞俄比亚儿科BSIs中日益严重的抗菌药物耐药威胁。加强常规抗菌药物敏感性检测、改善医疗基础设施以及提高公众对合理使用抗生素的认识至关重要。有针对性的干预措施对于指导有效治疗、预防治疗失败以及降低败血症相关死亡率至关重要。
