Understanding Cystic Fibrosis andDiabetes

Cystic fibrosis is an autosomal recessive disorder caused by mutations in thee CFTR gene, which encodes a chloridee channel expressed in epixial tissues. The resutting defect in ion ion transport leads to thick, viscous secreats in the lungs, creawanas, liver, equines, and reproductiva tract. Over 180,000 individuals worldieare fected.

CFRD is a distinct form of diabetes that shares of both type 1 and type 2 diabetes but is not identical to either. The primary defect is a progressive reduction in insulin secretion due to pationatic fibrosis and destruction of islet cells. However, unlike type 1 diabetes, authytent destruction is not thee mechanism, and some insulin sectory capacity often elens. Conevilty, F patients exhibilt lin resistence due tpe.

Acute illness - pulmonary insectations, viral infections, patititis, or gastroequity inal infections - provokes a stress responses that increases insulilin resistance and akcelerates lipolysis and ketogenesis.

Blood Glucose Monitoring i Keton Testing

For patients with a history of DKA or those prone to hyperglycemia, more frequent checks are providente. Blood ketone ketone boy, is specific, and providee realt result.

Nutritional Guidance andDietary Planning

Nutrition in CF is complex because patients need high-calorie, high-fat diets to maintain body weight and lung function. For patients with CFRD, dietary education must balance caloric needs with glucose control. Carbohydrate counting is the most effective method for matching prandial insulin doses, but the focus should be on consistent carbohydrate intake rather than severe restriction, which is not appropriate in this population. A dietitian with CF expertise should help patients and families identify carbohydrate-containing foods, teach label reading, and develop meal plans that incorporate enough fiber, protein, and healthy fats to slow glucose absorption. Fat malabsorption due to pancreatic insufficiency further complicates glucose excursions; enzyme replacement therapy should be optimized to improve nutrient digestion and reduce unpredictable glycemic swings.

Patient andCaregiver Education

Patients and caregivers must te recatize thee arilly signs of hyperglycemia (polyuria, polydipsia, nocturia) ante warning supmentoms of DKA: diseates, vomiting, abdominal pain, thiergue, tachypnea, and a fruty odor thee breath.

Sick Day Protocols

Every CF patient wigh diabetes should have a written chore- day plan that addisses monitoring frequency, insulin dose adjustments, hydration, and wheren to go tu thee hospital. A typical protocol included:

  • Sprawdź krew glukozy every 2- 4 godziny during illns.
  • Check blood ketone wigh each glucose check or at least every 4 hour if glucose indigt; 250 mg / dL.
  • Never stop insulin completely - basal insulin should be continued, often at higher Doses (np., 110- 120% of usual) during illns.
  • For pacjents who cannot eat solid food, replacee meals with carbohydrante- containg liquids (juice, regular soda, gelatin) to prevent hypoglycemia while keathaining glucose supply for energy.
  • If ketones are present and glucose is high, administration an extra dosie of rapid- acting insulin (np., 10- 20% of total daily dosie as correction) and precles fluid intake.
  • If vomiting persists, ketone rise above 1,5 mmol / L, glucose cannot be kept undecorn 300 mg / dL, or te patient becomes confused or tachypneic, seek emergency medical attention.
