Conventional measures underestimate glycaemia in cystic fibrosis patients

Abstract

We have shown that overall glycaemia, as shown by both the response during an OGTT and CGMS, is higher in CF subjects who have similar HbA(1c), fasting and 2-h glucose values. These results question whether it is appropriate to use the diagnostic thresholds and OGTT time points derived from the non-CF population for a diagnosis of diabetes in patients with cystic fibrosis.
