Summary

Cystic fibrosis related diabetes (CFRD) is a common co-morbidity in patients with CF. The underlying pathophysiology of cystic fibrosis related diabetes (CFRD) is still a matter of investigation. In addition to localized tissue damage developing similar to that of the exocrine pancreas, other mechanisms may be involved. We have shown that a potential contributing factor to the patho-physiology of CFRD may be an abnormal gut derived hormonal profile, specifically of lower incretin hormone responses, prior to development of CFRD.

We propose that an altered incretin response, probably due to impaired interaction of nutrients with the gut mucosa due to thickened secretions, may play a role in the development of the disease. Specifically, low GIP and GLP-1, may explain the poor β-cell function observed in these patients prior to CFRD appearance. These incretins have known trophic effects on β-cells, and thus their lower levels may contribute to the development of quantitative as well as qualitative defects in β-cell function and thus may lead to the development of CFRD. Thus, increasing levels of these incretins using a DPP-IV inhibitor may improve glucose metabolism and delay/prevent the development of CFRD.

We hypothesize that Saxagliptin will increase the oDI compared to placebo and will thus provide relative protection from diabetes development and in addition we expect that Saxagliptin will lead to overall increased insulin concentrations and thus shift the metabolic milieu to a more anabolic state. This will manifest as weight gain and reduction in inflammation.
