Bacterial pathogens and resistance causing community acquired paediatric bloodstream infections in low- and middle-income countries: a systematic review and meta-analysis

Background Despite a high mortality rate in childhood, there is limited evidence on the causes and outcomes of paediatric bloodstream infections from low- and middle-income countries (LMICs). We conducted a systematic review and meta-analysis to characterize the bacterial causes of paediatric bloodstream infections in LMICs and their resistance profile. Methods We searched Pubmed and Embase databases between January 1st 1990 and October 30th 2019, combining MeSH and free-text terms for “sepsis” and “low-middle-income countries” in children. Two reviewers screened articles and performed data extraction to identify studies investigating children (1 month-18 years), with at least one blood culture. The main outcomes of interests were the rate of positive blood cultures, the distribution of bacterial pathogens, the resistance patterns and the case-fatality rate. The proportions obtained from each study were pooled using the Freeman-Tukey double arcsine transformation, and a random-effect meta-analysis model was used. Results We identified 2403 eligible studies, 17 were included in the final review including 52,915 children (11 in Africa and 6 in Asia). The overall percentage of positive blood culture was 19.1% [95% CI: 12.0–27.5%]; 15.5% [8.4–24.4%] in Africa and 28.0% [13.2–45.8%] in Asia. A total of 4836 bacterial isolates were included in the studies; 2974 were Gram-negative (63.9% [52.2–74.9]) and 1858 were Gram-positive (35.8% [24.9–47.5]). In Asia, Salmonella typhi (26.2%) was the most commonly isolated pathogen, followed by Staphylococcus aureus (7.7%) whereas in Africa, S. aureus (17.8%) and Streptococcus pneumoniae (16.8%) were predominant followed by Escherichia coli (10.7%). S. aureus was more likely resistant to methicillin in Africa (29.5% vs. 7.9%), whereas E. coli was more frequently resistant to third-generation cephalosporins (31.2% vs. 21.2%), amikacin (29.6% vs. 0%) and ciprofloxacin (36.7% vs. 0%) in Asia. The overall estimate for case-fatality rate among 8 studies was 12.7% [6.6–20.2%]. Underlying conditions, such as malnutrition or HIV infection were assessed as a factor associated with bacteraemia in 4 studies each. Conclusions We observed a marked variation in pathogen distribution and their resistance profiles between Asia and Africa. Very limited data is available on underlying risk factors for bacteraemia, patterns of treatment of multidrug-resistant infections and predictors of adverse outcomes

Personal protective equipment (PPE) in a pandemic: Approaches to PPE preservation for South African healthcare facilities

Personal protective equipment (PPE) is key to protecting healthcare workers from COVID-19 infection, but the pandemic has disrupted supply chains globally and necessitated rapid review of the scientific evidence for PPE re-use. In South Africa, where the COVID-19 epidemic is still developing, healthcare facilities have a short window of opportunity to improve PPE supply chains, train staff on prudent PPE use, and devise plans to track and manage the inevitable increases in PPE demand. This article discusses the available PPE preservation strategies and addresses the issue of decontamination and re-use of N95 respirators as a last-resort strategy for critical shortages during the pandemic

A framework for preventing healthcare-associated infection in neonates and children in South Africa

Healthcare-associated infection (HAI) is a frequent and serious complication affecting 4 - 8% of hospitalised children and neonates in high-income countries. The burden of HAI in South African (SA) paediatric and neonatal wards is substantial but underappreciated, owing to a lack of HAI surveillance and reporting. Maternal and child health and infection prevention are priority areas for healthcare quality improvement in the National Core Standards programme. Despite increasing recognition in SA, infection prevention efforts targeting hospitalised children and neonates are hampered by health system, institutional and individual patient factors. To ensure safe healthcare delivery to children, a co-ordinated HAI prevention strategy should promote development of infection prevention norms and policies, education, patient safety advocacy, healthcare infrastructure, surveillance and research. We present a framework for SA to develop and expand HAI prevention in hospitalised neonates and children

A profile of HIV-related paediatric admissions at Chris Hani Baragwanath Hospital, Johannesburg, South Africa

MMed (Paediatrics), Faculty of Health Sciences, University of the Witwatersrand, 2009Aim: To describe the prevalence of HIV infection, and the disease profile and outcome of 440 HIV-infected children admitted to the general paediatric wards at Chris Hani Baragwanath Hospital (CHBH). Methods: A comprehensive list of all paediatic patients admitted to the general wards between October and December 2007 was compiled using hospital admission records. Hospital folder and laboratory records were used to determine HIV prevalence. A retrospective review of inpatient hospital records was conducted for all confirmed HIV-infected paediatric patients admitted during the study period. Results: The prevalence of confirmed HIV infection amongst paediatric admissions at CHBH during the study period was 29.5% (95% CI 27.2 -31.9%). Of these children, 54.1% were newly diagnosed with HIV during the current hospital admission. Despite the majority (92.7%) of admissions having advanced HIV disease (WHO Stage 3 or 4), only 17% were accessing ART. Of the 202/440 (45.9%) children known to be HIV-infected before hospital admission, only 74/202 (36.6%) were currently receiving ART. Of the remaining 128/202 children known to be HIV-infected before hospital admission, 121/128 (94.5%) had WHO HIV stage 3 or 4 disease and thus were eligible for ART. Only 19% of children had a normal weight. Amongst infants aged less than 6 months uptake of PMTCT interventions was poor - only 36% of mother-infant pairs received single dose nevirapine and 28% of infants received cotrimoxazole prophylaxis. Respiratory illness was the principal reason for hospitalization in 37.5% of admissions. Gastroenteritis, sepsis and tuberculosis accounted for 22%, 19.5% and 21% of principal diagnoses respectively. The overall case fatality rate was 12% (95% CI 9.2–15.5%), with deaths in HIV-infected children contributing 58% of all deaths in the general paediatric wards. Over half (52%) of all deaths in the HIV-infected group occurred in infants younger than 6 months of age. vi Conclusion: HIV infection remains a major contributor to morbidity and mortality among paediatric admissions at CHBH. Poor uptake of PMTCT interventions, late diagnosis of HIV infection and delay in accessing ART are immediate barriers to improved care in HIV-infected children at CHBH. The underlying reasons for poor accessibility and under- utilisation of paediatric HIV-related services requires further investigation. Efforts to reduce mortality amongst HIV-infected paediatric admissions at CHBH should focus on early diagnosis of HIV infection and prompt initiation of antiretroviral treatment, especially in infants under 6 months of age
