RESUMEN

Filamentous fungi are commonly isolated from the respiratory tract of CF patients, but their clinical significance is uncertain and the reported incidence variable. We report on the degree of Aspergillus fumigatus airway colonization in a tertiary pediatric CF cohort, evaluate the sensitivity of routine clinical sampling at detecting A. fumigatus, and compare lung function of A. fumigatus-colonized and non-colonized children.We carried out an 8-year retrospective cohort analysis using local databases, examining 1024 respiratory microbiological specimens from 45 children. Nineteen (42%) had a positive A. fumigatus culture at least once during the 8-year period, with 10 (22%) children persistently colonized. Overall, 29% of 48 bronchoalveolar lavage (BAL) samples tested positive for A. fumigatus, compared with 14% of 976 sputum samples. Of 33 children for whom lung function data were available during the study period, seven were classed as having severe lung disease, of whom four (57%) were persistently colonized with A. fumigatus.We conclude that chronic A. fumigatus colonization of the CF airway is common, and may be associated with worse lung function. In our practice, BAL appears superior at detecting lower airway A. fumigatus compared to sputum samples.

RESUMEN

BACKGROUND: Invasive group A streptococcal disease (iGAS) can have varied clinical presentations in children, are responsible for prolonged hospital stays and can cause mortality and long-term morbidity in children. Over the last decade, there has been an increase in the incidence of iGAS infections in the UK and worldwide. This has renewed the focus on early diagnosis, management and prevention of this disease. AIMS AND OBJECTIVES: The aim of this study was to review the varied clinical presentations and management of children with iGAS infections. METHODS: We reviewed the data of children admitted to our tertiary Children's Hospital who had positive isolation of Group A Streptococcus( GAS) from sterile site cultures over the last 8 years. We reviewed their clinical presentations and management including treatment given (antibiotics and duration), outcome and follow up. RESULTS: A total of 57 children had iGAS during the study period. The incidence of iGAS was 6-7 cases per year during the study period, except for 2015 when we had 11 cases. The mean length of stay of children admitted with iGAS was 11 days (range 2- 35 days). 21.1% children were admitted to intensive care during their hospital stay. Fever was the most common presenting symptom. Pneumonia with or without empyema was the most common Diagnosis. Initial antibiotic management was varied with ceftriaxone the most commonly used antibiotic in 30% of the cases. 50% of children had their antimicrobial therapy optimised to IV benzylpenicillin after the confirmed isolation of GAS. 7 Children were re-admitted for further treatment and needed a further course of antibiotics. 4 children (7%) died due to iGAS infection. CONCLUSION: Our study highlighted the varied symptomatology and management practices in children with iGAS and showed that early diagnosis and prompt initiation of appropriate antibiotics for iGAS can help in the resolution of symptoms and good outcomes.
