More research is needed on the use of probiotics for critically ill patients

We are grateful to Williams and Kumar Angurana (1) for their comments on our paper (2) in Acta Paediatrica and for providing the references to their own work on the use of probiotics for critically ill patients (3,4).However, the aim of our paper was to provide guidance to primary care paediatricians and physicians who face daily questions about what probiotic strain to give patients and for what clinical indications. Therefore, we summarised the scientifically accredited guidelines and recommendations that were available on the use of probiotics in paediatric healthcare practice at the time of our study and decided not to mention every randomised controlled trial.
