A limited role for microbiological testing for childhood lower respiratory tract infections in primary care: managing diagnostic uncertainty by withholding antibiotics and watchful waiting

Impact of antimicrobial resistance on infections in children in Africa

PURPOSE OF REVIEW

Antimicrobial resistance is an escalating public health threat in Africa, and an awareness of the devastating impact on children is growing. This review highlights the prevalence and patterns of antimicrobial resistance among children in Africa, focusing on pathogens responsible for bloodstream infections, community-acquired pneumonia, bacterial meningitis, neonatal infections, diarrhea and malaria. Current strategies to tackle antimicrobial resistance in pediatric populations are discussed.

RECENT FINDINGS

Bloodstream infections significantly contribute to child mortality, with high resistance observed in pathogens like Salmonella spp., Klebsiella spp., Escherichia coli , and Staphylococcus aureus . Additionally, rising resistance in pathogens causing community-acquired pneumonia, meningitis and bacterial diarrhea challenges the effectiveness of WHO-recommended therapies. Antibiotics used to treat neonatal infections, such as ampicillin, gentamicin and cefotaxime, are threatened by high resistance in Escherichia coli and Klebsiella spp , contributing to adverse neonatal outcomes. PfKelch 13 mutations linked to artemisinin resistance in parts of Africa raise public health concerns, as malaria remains a major cause of illness and death.

SUMMARY

Stronger collaborative efforts are needed to enhance surveillance, improve diagnostic capabilities and update treatment protocols based on local pathogen sensitivities. More research is required on pediatric antimicrobial resistance in Africa.

Childhood community-acquired pneumonia

Community-acquired pneumonia (CAP) is a common disease in children, and its aetiological and clinical diagnosis are challenging for physicians in both private practice and hospitals. Over the past three decades, conjugate vaccines have successfully reduced the burden of the former main causes of CAP, Streptococcus pneumoniae and Haemophilus influenzae type b. Today, viruses are by far the most commonly detected pathogens in children with CAP.  Conclusion: New insights into the aetiology and treatment of CAP in children in recent years have influenced management and are the focus of this review. In addition to reducing diagnostic uncertainty, there is an urgent need to reduce antibiotic overuse and antimicrobial resistance in children with CAP. What is Known: • Conjugate vaccines against Streptococcus pneumoniae and Haemophilus influenzae type b have shifted the epidemiology of childhood CAP to predominantly viral pathogens and Mycoplasma pneumoniae. • Clinical, laboratory, and radiological criteria cannot reliably distinguish between bacterial and viral aetiology in children with CAP. What is New: • Test results and epidemiological data must be carefully interpreted, as no single diagnostic method applied to non-pulmonary specimens has both high sensitivity and high specificity for determining pneumonia aetiology in childhood CAP. • This review provides a simple and pragmatic management algorithm for children with CAP to aid physicians in providing optimal and safe care and reducing antibiotic prescribing.
