Leukocyte Telomere Length Is Not Reduced in Children and Adults with Cystic Fibrosis but Associates with Clinical Characteristics-A Cross-Sectional Study.

ABSTRACT: We hypothezied that telomere length is considerably altered in cystic fibrosis (CF) patients compared to healthy subjects (HS), and that leukocyte telomere length variation reflects the severity of CF. Relative telomere length (RTL) was assessed by qPCR in 70 children aged 5-10 (34 CF; 36 HS) and 114 adults aged 18-45 (53 CF; 61 HS). Telomere length was similar in CF and HS (median (interquartile range): 0.799 (0.686-0.950) vs. 0.831 (0.707-0.986); p = 0.5283) both in children and adults. In adults, women had longer telomeres than men (0.805 (0.715-0.931) vs. 0.703 (0.574-0.790); p = 0.0002). Patients treated with inhaled corticosteroids had a shorter RTL compared to those without steroid therapy (0.765 (0.664-0.910) vs. 0.943 (0.813-1.191); p = 0.0007) and this finding remained significan
