Te Intersection of Cystic Fibrosis anddiabetes in Pediatrics

Cystic fibrosis (CF) is a life- shortening genetic disorder caused by mutations in thee CFTR gene, leading to difficiirod chlorite transport across nabłonkowi surfaces. Thee resutting thick, sticky secrets damage multiple organs, particarly the lungs andd pawias. Over time, progressive patic destruction reduces insulin production and alters glucose metabolizm, giving rise to cystic fibrovatisis- related diabetetes (CFRD).

Unlike type 1 diabetes (autoimpete beta- cell destruction) or type 2 diabetetes (insulin resistance with relative departency), CFRD is specifized primaryly byy insulin deserpency negated by intermittent insulin resistance during acute illness or matimation. Children with-crD typically retail some endogenous insulin secretion, but their ability te manage glucose loads from -calie CF diets is commoved.

Patofizjologia i Klinika Spectrum

Te allmark of CFRD is a combination of reduced insulin secretion (due to patiatic fibrosis and fatty infiltration) and variable distriveral insulin resistance. In children, then onset is often insidious. Unlike the classic hyperglycemic superitoms of type 1 diabetetes, CFRD may present with with decling lung functionion, pour weight gain, or pregloved pulmony erecbations rather than polyuria or polypsia.

Diagnostyka Wyzwania i Pediatryczne CFRD

Diagnozyng CFRD in children is fraught with pitfalls. Standard diabetes biomarkers perforom differently in the CF population:

Thee 2-hour glucose level ≥ 200 mg / dL confirms CFRD. Intermediate values (140- 199 mg / dL) indicate photoired glucose tolerance, which may procurt closer monitoring.

Future Directions andd Research

Advances in CFTR modulator therapies (np., elexaftor / tezacaftor / ivacaftor) have dramatically improwized lung function and quality of life for many children with CF.
