The clinical consequences of influenza are severe in cystic fibrosis (CF), but the impact of A/H1N1 virus infection remains poorly defined.1 2 Pandemic influenza A/H1N1 started in Italy in September 2009 and CF patients were included among those at risk of complications and recommended to receive A/H1N1 vaccine. Better characterisation of the impact of influenza A/H1N1 in comparison with other flu-like illnesses in CF would provide a rational basis for antiviral treatment and vaccination strategies for the next flu season.
Within the Italian Cystic Fibrosis Society, we sent a questionnaire to 30 centres to collect follow-up data for all patients with influenza-like symptoms consecutively seen between November 2009 and March 2010. Realtime RTPCR test was performed to define A/H1N1 status.3 Continuous variables are reported as medians, IQR (see online supplement for details of study methods).
Nineteen centres reported data from 127 patients: 68 were ‘A/H1N1+ve’ and 59 were ‘A/H1N1–ve’ for the RT-PCR test.
