📚 Academic Pearls & Pathophysiology
1. Pathophysiology: Why Sodium in MELD-Na?
The original MELD score relied only on Bilirubin, INR, and Creatinine. However, in advanced cirrhosis, severe portal hypertension triggers massive release of systemic vasodilators (like nitric oxide). This splanchnic vasodilation causes a drop in effective arterial blood volume, which triggers the baroreceptors to release massive amounts of non-osmotic Anti-Diuretic Hormone (ADH). This ADH causes profound free-water retention, resulting in dilutional hyponatraemia. Therefore, a low serum sodium (< 135 mEq/L) is a powerful, independent surrogate marker for extreme portal hypertension and poor survival, which is why it was added to the transplant allocation formula.
2. Malpractice Trap: Blind Steroids in Alcoholic Hepatitis
⚠ The Sepsis Trap in India: A Maddrey's Discriminant Function (mDF) ≥ 32 mathematically indicates severe alcoholic hepatitis with a high 1-month mortality, classically warranting corticosteroids (Prednisolone 40mg/day). HOWEVER, in the Indian clinical context, you MUST aggressively rule out occult infections (UTI, SBP, pneumonia) and latent Tuberculosis before initiating high-dose steroids. Steroids in a cirrhotic patient with untreated sepsis will cause rapid, fatal septic shock.
3. Illness Scripts: AKI in Cirrhosis
Condition
Pathophysiology
Volume Challenge Response
Pre-Renal Azotaemia
True volume depletion (over-diuresis, GI bleed, severe vomiting/diarrhoea).
Rapidly improves with IV Albumin/Fluids.
Hepatorenal Syndrome (HRS-AKI)
Extreme splanchnic vasodilation leading to compensatory, intense renal vasoconstriction. The kidneys are histologically normal but functionally starved of blood.
Refractory to volume expansion. Requires vasoconstrictors (Terlipressin) + Albumin to reverse splanchnic pooling.
Acute Tubular Necrosis (ATN)
Direct structural damage to renal tubules (ischaemic shock, nephrotoxic drugs, contrast).
Refractory to volume expansion. Urine will show muddy brown casts.
4. Strict Contraindications in Cirrhosis
Avoid NSAIDs & ACE-Inhibitors: Cirrhotic patients rely heavily on renal prostaglandins to keep their afferent renal arterioles dilated and maintain GFR. Administering an NSAID (which blocks prostaglandins) or an ACE-Inhibitor will instantly precipitate acute renal failure.
