Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) caused coronavirus disease 2019 (COVID-19) pandemic with major disruptions globally. Northwest Province Department of Health (NWDoH) in South Africa set up comprehensive epidemiological emergency response plans for preventing, finding, containing and stopping the spread of COVID-19 in accordance with the National Disaster Management Act.Objectives: This After-Action Report (AAR) describes the provincial response to the pandemic from September 2020 to October 2022.Method: The AAR was conducted using the World Health Organization AAR methodology. Focus groups discussed five items: coordination, leadership and governance; epidemiology, surveillance and laboratory; case management and continuity of essential services; risk communication and community engagement and COVID-19 vaccination.Results: The timely establishment and activation of provincial intergovernmental and intersectoral coordinating structures led to effective coordination, resource mobilisation, leadership, decision-making and intervention. The effective communication in the department and other stakeholders resulted in improved surveillance data quality, timelier response and increased ownership of data. Dissemination, training and implementation of case management protocols ensured standardised case management. The multi-channel information dissemination targeting different audiences empowered people with real-time knowledge on the infection and encouraged health-seeking behaviours.Conclusion: The AAR demonstrated the importance of coordinated epidemiological, laboratory and communication response that requires significant public health reserve capacity in peacetime for rapid expansion in an emergency.Contribution: This review contributes to the body of knowledge emerging from the COVID-19 pandemic and provides guidance on enhanced public health response to future emergencies.
背景:严重急性呼吸系统综合征冠状病毒 2(SARS-CoV-2)引发了冠状病毒病 2019(COVID-19)大流行,在全球范围内造成了严重破坏。南非西北省卫生厅(NWDoH)根据《国家灾害管理法》制定了全面的流行病应急计划,以预防、发现、控制和阻止 COVID-19 的传播:本行动后报告(AAR)介绍了 2020 年 9 月至 2022 年 10 月期间各省应对大流行病的情况:AAR 采用世界卫生组织的 AAR 方法进行。重点小组讨论了五个项目:协调、领导和治理;流行病学、监测和实验室;病例管理和基本服务的连续性;风险沟通和社区参与以及 COVID-19 疫苗接种:结果:省级政府间和部门间协调机构的及时建立和启动促成了有效的协调、资源调动、领导、决策和干预。该省与其他利益相关方的有效沟通提高了监测数据的质量,使反应更加及时,并增强了数据的所有权。病例管理规程的传播、培训和实施确保了病例管理的标准化。针对不同受众的多渠道信息传播增强了人们对感染的实时了解,并鼓励了寻求健康的行为:AAR 表明了协调流行病学、实验室和通信应对措施的重要性,在和平时期需要大量的公共卫生储备能力,以便在紧急情况下迅速扩展:贡献:本综述有助于丰富从 COVID-19 大流行中获得的知识,并为加强对未来紧急情况的公共卫生响应提供指导。

Background: The emergence of genetic variants of SARS-CoV-2 was associated with changing epidemiological characteristics throughout coronavirus disease 2019 (COVID-19) pandemic in population-based studies. Individual-level data on the clinical characteristics of infection with different SARS-CoV-2 variants in African countries is less well documented.Objectives: To describe the evolving clinical differences observed with the various SARS-CoV-2 variants of concern and compare the Omicron-driven wave in infections to the previous Delta-driven wave.Method: We performed a retrospective observational cohort study among patients admitted to a South African referral hospital with COVID-19 pneumonia. Patients were stratified by epidemiological wave period, and in a subset, the variants associated with each wave were confirmed by genomic sequencing. Outcomes were analysed by Cox proportional hazard models.Results: We included 1689 patients were included, representing infection waves driven predominantly by ancestral, Beta, Delta and Omicron BA1/BA2 BA4/BA5 variants. Crude 28-day mortality was 25.8% (34/133) in the Omicron wave period versus 37.1% (138/374) in the Delta wave period (hazard ratio [HR] 0.68 [95% CI 0.47–1.00] p = 0.049); this effect persisted after adjustment for age, gender, HIV status and presence of cardiovascular disease (adjusted HR [aHR] 0.43 [95% CI 0.28–0.67] p  0.001). Hospital-wide SARS-CoV-2 admissions and deaths were highest during the Delta wave period, with a decoupling of SARS-CoV-2 deaths and overall deaths thereafter.Conclusion: There was lower in-hospital mortality during Omicron-driven waves compared with the prior Delta wave, despite patients admitted during the Omicron wave being at higher risk.Contribution: This study summarises clinical characteristics associated with SARS-CoV-2 variants during the COVID-19 pandemic at a South African tertiary hospital, demonstrating a waning impact of COVID-19 on healthcare services over time despite epidemic waves driven by new variants. Findings suggest the absence of increasing virulence from later variants and protection from population and individual-level immunity. 
背景:在基于人群的研究中,SARS-CoV-2 基因变异体的出现与 2019 年冠状病毒病(COVID-19)大流行期间流行病学特征的变化有关。关于非洲国家感染不同SARS-CoV-2变体的临床特征的个人层面数据记录较少:目的:描述所观察到的不同 SARS-CoV-2 变体在临床上的演变差异,并将 Omicron 驱动的感染浪潮与之前的 Delta 驱动的感染浪潮进行比较:我们对南非一家转诊医院收治的 COVID-19 肺炎患者进行了一项回顾性观察队列研究。根据流行病学波段对患者进行了分层,并通过基因组测序确认了与每个波段相关的变异。结果采用 Cox 比例危险模型进行分析:我们共纳入了 1689 名患者,他们代表了主要由祖先、Beta、Delta 和 Omicron BA1/BA2 BA4/BA5 变体驱动的感染波。在 Omicron 波段中,28 天的粗死亡率为 25.8%(34/133),而在 Delta 波段中,死亡率为 37.1%(138/374)(危险比 [HR] 0.68 [95% CI 0.47-1.00] p = 0.049);在对年龄、性别、HIV 感染状况和是否患有心血管疾病进行调整后,这一效应依然存在(调整后 HR [aHR] 0.43 [95% CI 0.28-0.67] p 0.001)。在德尔塔波期间,全院 SARS-CoV-2 入院人数和死亡人数最高,此后 SARS-CoV-2 死亡人数与总体死亡人数脱钩:结论:与之前的德尔塔波相比,欧米茄波期间的院内死亡率较低,尽管欧米茄波期间入院的患者风险较高:本研究总结了南非一家三甲医院在 COVID-19 大流行期间与 SARS-CoV-2 变体相关的临床特征,表明尽管新变体引发了流行浪潮,但随着时间的推移,COVID-19 对医疗服务的影响在逐渐减弱。研究结果表明,后期变种的毒力并没有增强,而人群和个人的免疫力则起到了保护作用。

Background: Neonatal sepsis remains a major cause of morbidity and mortality. Therefore, early detection and initiation of appropriate empirical antibiotic therapy are crucial.Objectives: The aim of this study was to describe the antibiogram of the neonatal intensive care unit at Grey’s Hospital, a tertiary hospital in KwaZulu-Natal.Method: This was a retrospective descriptive study, reviewing positive cultures from Grey’s Hospital tertiary neonatal intensive care unit (NICU) in KwaZulu-Natal, South Africa for a 3-year period (01 January 2017 to 31 December 2019). All positive cultures from all sites were included.Results: There were 1314 positive organisms cultured. Late-onset sepsis (89.3%) predominated over early-onset sepsis (10.7%). Blood was the source for 55.2% (725/1314) of positive cultures. Of the 1314 organisms cultured, 53.7% (706/1314) were Gram-positive, 45.7% (601/1314) were Gram-negative and 0.5% (7/1314) were Candida species. Klebsiella pneumoniae, 23.5% (313/1314) was the most frequent Gram-negative organism. It was noted to have high resistance to the unit’s first-line antibiotic regimens; 99% were resistant to ampicillin and 92% resistant to gentamicin.Conclusion: Blood cultures yielded most positive results with a predominance of Gram-positive organisms and late-onset sepsis. A significant proportion of the cultured organisms were resistant to the first-line antimicrobials utilised in the unit, ampicillin and gentamicin.Contribution: Ongoing surveillance on positive cultures is recommended to assess the effectiveness of the unit’s current empirical antimicrobial guideline.
背景:新生儿脓毒症仍然是发病率和死亡率的主要原因。因此,早期发现和开始适当的经验性抗生素治疗至关重要。目的:本研究的目的是描述夸祖鲁-纳塔尔省三级医院Grey医院新生儿重症监护病房的抗生素谱。方法:这是一项回顾性描述性研究,回顾了南非夸祖鲁-纳塔尔省格雷医院三级新生儿重症监护病房(NICU) 3年(2017年1月1日至2019年12月31日)的阳性培养。包括所有地点的阳性培养物。结果:共培养阳性菌1314株。迟发性败血症(89.3%)高于早发性败血症(10.7%)。血液是55.2%(725/1314)阳性培养的来源。其中革兰氏菌阳性53.7%(706/1314),革兰氏菌阴性45.7%(601/1314),念珠菌0.5%(7/1314)。最常见的革兰氏阴性菌为肺炎克雷伯菌,占23.5%(313/1314)。人们注意到它对该单位的一线抗生素方案具有高度耐药性;99%对氨苄西林耐药,92%对庆大霉素耐药。结论:血培养结果阳性,以革兰氏阳性菌和迟发性败血症为主。培养的微生物中有很大一部分对该单位使用的一线抗菌剂氨苄西林和庆大霉素具有耐药性。贡献:建议对阳性培养物进行持续监测,以评估该单位当前经验性抗菌指南的有效性。

Leptospirosis is an under-recognised disease in sub-Saharan Africa and the diagnosis requires a high index of suspicion. This case report highlights the protean manifestations of leptospirosis. Leptospirosis should be considered in any patient presenting with fever and jaundice, especially when there has been a history of occupational or recreational exposure to water, soil or rodents.

Contribution: This case report describes a typical case of leptospirosis, which often presents as a diagnostic dilemma.

在撒哈拉以南非洲,钩端螺旋体病是一种未得到充分认识的疾病,诊断需要高度怀疑。本病例报告强调了钩端螺旋体病的多种表现。任何出现发热和黄疸症状的患者都应考虑钩端螺旋体病,特别是有职业或娱乐接触水、土壤或啮齿动物史的患者。贡献:本病例报告描述了一个典型的钩端螺旋体病病例,它通常表现为诊断困境。

Non-fermenter Gram-negative bacilli at a tertiary hospital, South Africa. 南非一家三级医院的非发酵革兰氏阴性杆菌。

Background: Non-fermenting Gram-negative bacilli (NFGNB) are a significant cause of healthcare-associated infections and are often implicated in nosocomial outbreaks. Non- fermenting Gram-negative bacilli tend to have variable susceptibility patterns that make the choice of empiric therapy difficult and thus treatment must be based on in vitro susceptibility testing of each antimicrobial agent.

Objectives: To describe the epidemiology of the NFGNB isolated from adult patients at Chris Hani Baragwanath Hospital (CHBAH) and to assess their antimicrobial susceptibility patterns in order to guide empiric therapy and inform infection prevention and control practices.

Method: Organisms isolated from sterile sites of adult in-patients between 01 January 2016 to 31 December 2018 were retrospectively analysed.

Results: A total of 2005 NFGNB isolated. Blood cultures were the most common specimen type (91.4%). Acinetobacter species were the most commonly isolated organisms (65.1%), followed by Pseudomonas species (26.5%). The majority of NFGNB were isolated from patients in surgical wards (38.9%) followed by medical wards (35.2%). Most (60%) of the Acinetobacter species were extremely drug resistant. Pseudomonas species were more susceptible than the Acinetobacter species with an overall susceptibility rate of 86% for Pseudomonas species.

Conclusion: The rates of antimicrobial resistance demonstrated among Acinetobacter and Pseudomonas species were high, which illustrates the threat of antimicrobial resistance also seen worldwide. An emergence of NFGNB with intrinsic multidrug resistance (Stenotrophomonas maltophilia and Burkholderia cepacia) was noted. We suggest empiric therapy with a carbapenem sparing regimen of piperacillin-tazobactam in combination with amikacin and that empiric therapy be reviewed annually when cumulative antibiograms are done.

Contribution: Understanding of the distribution and antimicrobial susceptibility patterns of NFGNB at CHBAH.

背景:非发酵革兰氏阴性杆菌(NFGNB)是卫生保健相关感染的重要原因,经常与医院暴发有关。非发酵革兰氏阴性杆菌往往具有可变的药敏模式,这使得选择经验性治疗变得困难,因此治疗必须基于每种抗菌药物的体外药敏试验。目的:描述Chris Hani Baragwanath医院(CHBAH)成年患者分离的NFGNB的流行病学,并评估其抗菌药物敏感性模式,以指导经验性治疗并为感染预防和控制实践提供信息。方法:回顾性分析2016年1月1日至2018年12月31日成人住院患者无菌部位分离的微生物。结果:共分离NFGNB 2005例。血培养是最常见的标本类型(91.4%)。最常见的分离菌种是不动杆菌(65.1%),其次是假单胞菌(26.5%)。NFGNB主要来自外科病房(38.9%),其次是内科病房(35.2%)。大多数(60%)不动杆菌具有极强的耐药性。假单胞菌比不动杆菌更敏感,对假单胞菌的总敏感率为86%。结论:不动杆菌和假单胞菌对抗生素的耐药率较高,表明抗生素耐药性的威胁在世界范围内也存在。NFGNB出现了内在的多药耐药(嗜麦芽窄养单胞菌和洋葱伯克霍尔德菌)。我们建议经验性治疗为保留碳青霉烯的哌拉西林-他唑巴坦联合阿米卡星方案,并建议经验性治疗在累积抗生素图完成后每年进行回顾。贡献:了解NFGNB在CHBAH的分布和抗菌敏感性模式。

Background Antimicrobial stewardship principles guide the clinical use of antimicrobials, including vancomycin, but paediatric vancomycin prescribing practices have not been evaluated in South Africa. Objectives To document the use, prescribing practices and monitoring of intravenous vancomycin and the spectrum of bacteria isolated on microbiological culture in children treated with intravenous vancomycin during a 12-month period at Red Cross War Memorial Children’s Hospital (RCWMCH). Method A retrospective audit of intravenous vancomycin use in children admitted to RCWMCH during 2019 was performed. Results All 158 vancomycin prescription episodes for 143 children were included. Overall usage of intravenous vancomycin was 63 days of therapy per 1000 patient days (interquartile range [IQR]: 38–72). The median starting dose was 15 mg/kg per dose (IQR: 14–15) and median daily dose was 45 mg/kg per day (IQR: 43–60). Vancomycin was prescribed as empiric (127/158, 80%) and directed (31/158, 20%) treatment. The median duration of treatment for the directed group (7 days) was longer than the empiric group (4 days) (p = 0.001). Vancomycin serum trough concentrations were performed in 65/98 (66%) episodes where vancomycin treatment exceeded 3 days, with only 16/65 (25%) of these samples obtained before the fourth dose. Prolonged antibiotic treatment of 14 days or more was not associated with Gram-positive bacteria on culture (odds ratio [OR]: 1.02, 95% confidence interval [CI]: 0.17–4.2). Conclusion Dosing errors, prolonged empiric treatment and inappropriate vancomycin monitoring were problems associated with vancomycin prescriptions. Contribution The study identified multiple opportunities for improved vancomycin prescribing and monitoring. Further research and implementation of improved prescribing practices could contribute to the preservation of vancomycin as an effective antibiotic.

Chronic schistosomiasis affects either the genitourinary or gastrointestinal tract. Rarely, schistosomes cause ectopic disease, such as in the case of a South African woman from a non-endemic province, who presented with suspected pericardial tamponade because of tuberculosis. However, histology and polymerase chain reaction from pericardial biopsy confirmed Schistosoma haematobium. A finding of mediastinal non-Hodgkin lymphoma came to light when our patient's clinical condition unexpectedly deteriorated.

Contribution: This case highlights an unusual manifestation of schistosomiasis.

慢性血吸虫病影响泌尿生殖道或胃肠道。血吸虫病很少引起异位疾病,例如一名来自非流行省份的南非妇女,她因肺结核疑似心包填塞。然而,心包活检的组织学和聚合酶链式反应证实了血吸虫病。当我们的患者的临床状况意外恶化时,纵隔非霍奇金淋巴瘤的发现曝光了。贡献:该病例突出了血吸虫病的一种不寻常表现。

Background Efavirenz (EFV) is associated with neuropsychiatric symptoms. Severe neurotoxicity has been reported but the clinical phenotype and risk factors are poorly defined. Objectives To characterise clinical presentations, risk factors and outcomes to help clinicians recognise severe neurotoxicity earlier. Method The authors retrospectively identified adults with supratherapeutic EFV concentrations (> 4 mg/L) obtained during routine clinical care in Cape Town, South Africa. Clinical and laboratory data at the time of EFV quantification were extracted from medical records. Logistic regression was performed to identify associations with neuropsychiatric symptoms, and with severe neurotoxicity. Results Eighty one patients were included; 62 with neuropsychiatric manifestations (most frequently ataxia [n = 20] and psychomotor slowing [n = 24]); and 19 with hepatotoxicity. Overall, 28 (34.6%) were male, 49 (60.5%) had concomitant isoniazid exposure, and median EFV concentration was 12.1 mg/L (interquartile range [IQR]: 6.6–20.0). Neuropsychiatric symptoms were associated with longer duration of EFV therapy, adjusted odds ratio (aOR) 1.3/180-day increment (95% confidence interval [CI]: 1.0–1.7); higher EFV concentrations, aOR 1.2/1 mg/L increase (95% CI: 1.0–1.4) and isoniazid exposure, aOR 8.2 (95% CI: 2.5–26.7). Severe neuropsychiatric symptoms occurred in 47 (75%) patients at a median of 5.9 months (IQR: 2.1–40.8) after EFV initiation. Severe symptoms odds were 1.2-fold higher (95% CI: 1.1–1.4) per 1 mg/L increase in EFV concentration. Symptoms resolved completely within 1 month in 25 (76%) patients with severe neurotoxicity who discontinued EFV. Conclusion A concentration–effect relationship for severe neurotoxicity exists, which occurred late and resolved in most patients after EFV discontinuation. Contribution The authors highlighted clinical heterogeneity and morbidity of EFV-associated neurotoxicity.
背景:依非韦仑(EFV)与神经精神症状有关。严重的神经毒性已有报道,但临床表型和危险因素尚不明确。目的:描述临床表现、危险因素和结果,以帮助临床医生更早地识别严重的神经毒性。方法:作者回顾性地确定了在南非开普敦的常规临床护理中获得的超治疗性EFV浓度(>4 mg/L)的成年人。从医疗记录中提取EFV定量时的临床和实验室数据。进行Logistic回归以确定与神经精神症状和严重神经毒性的相关性。结果:纳入81例患者;62例有神经精神表现(最常见的是共济失调[n=20]和精神运动迟缓[n=24]);肝毒性19例。总体而言,28例(34.6%)为男性,49例(60.5%)同时接触异烟肼,EFV的中位浓度为12.1 mg/L(四分位间距[IQR]:6.6-20.0)。神经精神症状与EFV治疗持续时间更长、调整比值比(aOR)1.3/180天增加(95%置信区间[CI]:1.0-1.7)有关;EFV浓度越高,aOR增加1.2/1 mg/L(95%CI:1.0-1.4),异烟肼暴露,aOR 8.2(95%CI:2.5-26.7)。47名(75%)患者在EFV开始后的中位5.9个月(IQR:2.1-40.8)出现严重的神经精神症状。EFV浓度每增加1 mg/L,出现严重症状的几率就高出1.2倍(95%可信区间:1.1-1.4)。25例(76%)严重神经毒性患者停用EFV后,症状在1个月内完全缓解。结论:严重神经毒性存在浓度-效应关系,这种关系发生得较晚,大多数患者在EFV停用后症状缓解。贡献:作者强调了EFV相关神经毒性的临床异质性和发病率。
