Nutritional Management of Chronic Diseases

Celiac Disease - Gluten Gone!

• Immune reaction to gluten (proteins in wheat, rye, barley) causing small intestinal villous atrophy & malabsorption.
• Clinical Features:
  • GI: Chronic diarrhea, failure to thrive (FTT), abdominal pain/distension.
  • Non-GI: Iron deficiency anemia, short stature, dental enamel defects, dermatitis herpetiformis.
• Diagnosis:
  • Serology: IgA anti-tissue transglutaminase (Anti-tTG IgA) is the primary screening test. iv - Endoscopy with duodenal biopsy: Confirmatory; shows villous atrophy, crypt hyperplasia, increased intraepithelial lymphocytes.
• Management:
  • Lifelong strict Gluten-Free Diet (GFD).
  • Avoid: Wheat, Rye, Barley, and oats not certified gluten-free. (📌 BROW: Barley, Rye, Oats, Wheat).
  • Allowed: Rice, corn, millets, quinoa, potatoes, fruits, vegetables.
  • Monitor & supplement: Iron, folate, Vitamin D, calcium, B12.

⭐ Dermatitis herpetiformis, an intensely pruritic papulovesicular rash typically on extensor surfaces, is the specific cutaneous manifestation of celiac disease and responds to a GFD.

Cystic Fibrosis - CF Calorie Crusade

• Goal: Optimize nutrition, promote growth, prevent deficiencies.
• Energy: High needs: 110-200% of RDA.
• Diet: High-calorie, high-fat, high-protein. Unrestricted fat.
• PERT: Pancreatic Enzyme Replacement Therapy with all meals/snacks.
  • Lipase: 500-2,500 U/kg/meal; max 10,000 U/kg/day or <4,000 U/g fat/day.
• Vitamins: Fat-soluble (A, D, E, K) supplementation. 📌 ADEK for CF's sake.
• Minerals: Salt supplementation, especially with ↑sweat loss (e.g., fever, hot weather).
• Monitoring: Growth (weight, height, BMI), stool (steatorrhea), annual vitamin levels.

⭐ Pancreatic insufficiency, seen in 85-90% of CF patients, mandates lifelong enzyme therapy.

IBD Nutrition - Gut Guardian Grub

• Goal: Induce/maintain remission, correct deficiencies, promote growth. Growth failure common; requires aggressive support.
• Crohn's Disease (CD) - Active:
  • Exclusive Enteral Nutrition (EEN): First-line therapy.
    • Duration: 6-8 weeks.
    • Mechanism: ↓ inflammation, alters microbiome, mucosal healing.
    • Polymeric formulas often used.
    • 📌 EEN for Effective Eradication of Nasty CD flares.
• CD - Maintenance:
  • Partial Enteral Nutrition (PEN).
  • Specific diets (CDED, SCD) - emerging evidence.
• Ulcerative Colitis (UC):
  • EEN less established; supportive nutrition crucial.
• Key Deficiencies: Monitor & replete Fe, Vit D, B12, Zn, Folate.

⭐ EEN is as effective as corticosteroids for inducing remission in pediatric Crohn's disease, with superior mucosal healing and fewer side effects.

CKD Nutrition - Kidney Care Kitchen

• Key Goals: Support growth, manage complications (uremia, acidosis, bone disease).
• Energy: Meet RDA for height-age; ↑ for catch-up growth.
• Protein (HBV):
  • Pre-dialysis: RDA, may need moderate restriction (~0.8-1.0 g/kg/day).
  • Dialysis: ↑ needs (1.0-1.5 g/kg/day).
• Sodium: Restrict (e.g., 1-3 mEq/kg/day or <2 g/day); individualize fluid.
• Potassium: Restrict if K$^+$ > 5.5 mEq/L. Avoid high-K foods.
• Phosphorus: Restrict; use phosphate binders. Target age-specific levels.
• Vitamins/Minerals:
  • Active Vitamin D (e.g., Calcitriol).
  • Iron, water-soluble vitamins (B, C, Folic acid).

⭐ Protein needs ↑ significantly on dialysis due to losses & increased catabolism.

High‑Yield Points - ⚡ Biggest Takeaways

• Cystic Fibrosis: High-calorie, high-protein, high-fat diet; pancreatic enzyme replacement (PERT).
• Celiac Disease: Lifelong strict gluten-free diet (no wheat, barley, rye).
• IBD (Crohn's): Exclusive Enteral Nutrition (EEN) for induction; monitor micronutrients.
• CKD: Protein restriction (stage-dependent), phosphorus control, ensure adequate calories.
• IEMs (e.g., PKU): Disease-specific dietary modifications and special formulas.
• T1DM: Carbohydrate counting, balanced meals, match insulin regimen.
• Chronic Liver Disease: Medium-chain triglycerides (MCTs), fat-soluble vitamin support_._
