Pathophysiologie of CFRD in the Aging Panscrys

CFRD results from progressive destruction of pankreatic islet cells due to thoe underlying CFTR mutation, lealing to insulin deficiency. Over time, fibrosis and fatty infiltration of the pancorps reduce beta cell mass. In older adults, this longstanding deficit is comptended by agy age agedrelated declines in insulin sekretion and concented peristeraol insulin resistance.

Diagnosis and Screening

Te gold standard for CFRD diagnostis estas thee oral glucose tolerance test (OGTT), perfomed annually in all peoples with cystic fibrosis aged 10 and older. Hemoglobin A1c is less reliable in CFRD because of altered red blood cell turnover, recent illness, and malnutrition.

Special Challenges in Older Adults with CFRD

Hypoglycemia Risk

Older cients with CFRD are at heimenged risk for hypoglycemia due to unpredictabel appetite, delayed gazc emptying, erratic tententinal absorption from pankreatic insuficiency, and potential renal contenment that affects insulin clearance. In addition, thee use of intermediate acting insulins or sulfonylureas (though rare in CFRD) can exantioe low glucosa events.

Azl Function and Medication Adjustments

Kidney function naturally declines with age, and cumulative exposure to nefrotoxic agents (aminoglykosids, immunosupresants) makes older CF patients particarly contenable. Impaired renal funktion reduces insulin clearance, lengging the action of exogenous insulin and recreting hypoglycemia risk.

Both CF and diabetes indepently contribute to the bone mineral density. Older adults with CFRD face a comphabded risk of osteoporosis, vertebral fractres, and hip fractres. Vitamin D and calcium supplementation madbe optimized. DEXA scans are recompetended every 1-2 years in CF patients over 40. For those with conditetetetes, avoid thiadinedioneos (if used) becauses they worsen bone loss; insulin and metformin are neutral or beneficial.

Contrament Strategies for Older Adults

Insulin Therapy

Insulin levels the mainstay of CFRD management. In older adults, the goals are to maintain near normal glycemic levels while minimizing hypglycemia. Basal insulin (glargine, degludec) is preferend once daily. For prandial covelage, ultra acrirapid acting analogues (lispro, aspart, glulisine) or faster concluacting insulins (Fiasp) allow more flexibility.

Oral Agents: Limited Role
