Abstract
BackgroundWith improved prognosis of CF, comorbidities including chronic kidney disease (CKD) are becoming increasingly important. Identification of those at highest CKD risk is hence a priority. MethodsIn this cross-sectional study, adults with CF attending the Copenhagen CF Centre at Rigshospitalet with ≥2 measurements of serum creatinine from 2013 to 2015 were included. Data was obtained from an electronic CF database, which contains anonymised clinical and laboratory data on all individuals attending the clinic. CKD was defined as a confirmed (≥3months apart) estimated glomerular filtration rate≤60mL/min/1.73m2. ResultsOf 181 individuals, the CKD prevalence was 2.7% and increased to 11% after inclusion of lung transplanted patients. Individuals with CKD were generally older (median 39 (IQR, 36–45) vs. 31 (IQR, 24–39) years; p<0.001), diabetic (86% vs. 41%, p<0.001), with longer median duration of chronic pulmonary infection (28.3 (20.0–35.8) vs. 20.0 (9.9–34.7) years; p=0.008) and with longer intravenous aminoglycosides use (606 (IQR, 455–917) vs. 273 (IQR, 91–826) days, p=0.005). ConclusionsThe CKD prevalence is high and related to age, diabetes, chronic infection, transplantation and aminoglycosides use. These observations call for longitudinal studies investigating CKD predictors in adults with CF.
