Review shows paediatric protracted bacterial bronchitis needs an accurate diagnosis and strictly targeted extended antibiotics

Abstract Aim In 2017, the European Respiratory Society task force stated that protracted bacterial bronchitis ( PBB ) was a distinct clinical entity and outlined the diagnostic criteria and principles for treatment. However, this guidance was based on data from Australia and the USA . This mini review evaluated the data and addressed the lack of research‐based data from Europe. Methods We supplemented the 2017 report by conducting a nonsystematic review of the literature on prolonged wet or productive cough and on PBB in children up to September 2018. Results Our review confirmed the lack of European data on PBB . Based on the available literature, and the 2017 European guidance, PBB is a wet or productive cough that lasts for four or more weeks, with no signs or symptoms, known as specific cough pointers, which suggest an underlying illness. PBB usually recovers with appropriate antibiotics for two weeks. Failing that radiological investigations or lung function measurements are needed. If PBB occurs three times over 12 months, then computerised tomography can diagnose bronchiectasis and determine other permanent changes. Conclusion More data are needed on PBB , especially in Europe. The implementation of PBB may help clinicians to prescribe antibiotics more effectively and reduce their inappropriate use.
