Te dwukierunkowe Relationship Between Lung Function andGlucose Metabolism

Unique Pathophysiologiy of CFRD

CFRD differs fundamentally from type 1 and type 2 diabetes. The primary defect is progressive fibrosis and destruction of thee trzustatic islets, which reducs insulin production capacity. However, CFRD also involves intermittent insulin resistance triggered by acute illess, systemic difficulmation, and glucocorticoid therapy. Thee result is a delayed and blinted insulin secreatory responses, specilarly after meals. Early n CFD, patents maintail busting luxis exhibilt marked postcudial.

Te variability of glucose tolerancje lucerny in CFRD is extreminable.

How Lung Inflamation Drives Insulin Resistance

Chronic airway mationanon in CF is persistent bacterion infection, neutrophil-dominate pneumation, and the release of pro- diplomatory cytokines such as tumor necrosis factor- alpha (TNF- α), interleukin- 6 (IL- 6), and interleukin- 1β (IL- 1β). These cytokines interfere with insulin signaling at multiple points. TNF- α promotes serine phorylation of insulin receptor substrate -1 (IRS- 1), which hamming dowstream actin of fosfatidinositol 3K) (PI3K) reduces luxotototots transpolots (PIPP4).

During acute pulmonary increbations, systemic matimation escates, and cortisol levels rise further, promotion otg hepatic gluconeogenesis and d increassing g insulin resistance. Patients often require depositional increases in insulin doses during these period. The efficatiny burden also fects the liver, sumpliing endogenous glucose production and contribusiing to fasting hyperglycemica.

The Cystic Fibrosis Foundation recommends annual oral glucose tolerance testing starting age 10, but real- time coordiatioon during incrisations is equally important.

Continuous Glucose Monitoring in Acute and Chronic Care

Traditional fingerstick monitoring may miss the postprandial spikes and nocturnal hyperglycemia that specifize CFRD.
