Simplification of CF-related Diabetes Screening at Home (AtHome)
Cystic fibrosis (CF)-related diabetes (CFRD) is the most common complication after pulmonary complications. This specific form of diabetes is associated with an increased morbidity and mortality. CFRD prevalence at the age of 10 is 10% and reaches 40 to 50% in adulthood, while another 35% of adult patients presents impaired glucose tolerance. In order to identify patients at risk and to implement early therapeutic measures, an annual CFRD screening test should therefore be undertaken for CF patients after 10 years of age. The 2-hour oral glucose tolerance test (OGTT) with a sweet beverage is the recommended screening test. However, participation rates for screening tests are far from optimal. For examples, in 2015, the investigators observed that only 47% of non-diabetic patients attended to planned screening despite large availability and advertisement (unpublished data). Comparable low levels of screening for CFRD, usually below 33%, have been reported by various teams. Several reasons could explain these low adherence rates. Some factors are related to patients perceptions and experience: OGTT is perceived as an additional medical burden requiring a scheduled appointment (several weeks after the last exacerbation); overnight fasting followed by the intake of a large glucose load within 5 minutes can lead to nausea, headache, bloating and fatigue; some patients fear multiple blood sampling, etc. In addition, in case of CFRD diagnosis, recommended capillary blood glucose monitoring, nutritional advice and treatment (insulin) are perceived as extremely invasive and complex, thus some patients prefer avoiding screening test. To date, no alternative screening method has demonstrated its effectiveness to screen for CFRD. The investigators of this study believe that a simplified version of the OGTT would be more attractive, would make it more acceptable for patients and has the potential to improve their adherence to screening tests, simplify CF-team works and reduce costs. By allowing appropriate education and introduction of treatment in a timely manner, improved adherence to annual screening for dysglycemia has the potential to minimize or prevent clinical deterioration observed in years preceding CFRD onset.
