BACKGROUND AND AIMS: Nonselective beta-blockers (NSBB) are the mainstay for treatment of portal hypertension (PH), but require caution in decompensated cirrhosis (DC) or acute-on-chronic liver failure (ACLF) with hypotension, hyponatremia, acute kidney injury (AKI) or type 2 hepatorenal syndrome (HRS). Midodrine is oral, rapidly acting, α1-adrenergic agonist. We evaluated acute effects of midodrine on hepatic venous pressure gradient (HVPG) in DC and ACLF with contraindications to NSBB.
METHODS: Patients of DC (n = 30) with grade III ascites and serum sodium (Na) <130/systolic blood pressure (SBP) <90/type II HRS (group I) and ACLF patients (n = 30) with Na <130/SBP <90/AKI (group II) were included. HVPG was done at baseline and repeated 3 h after 10 mg midodrine. Primary outcome was HVPG response (reduction by >20% or to <12 mmHg).
RESULTS: In group I, midodrine significantly reduced HVPG (19.2 ± 4.6 to 17.8 ± 4.2, p = .02) and heart rate (HR) (86.3 ± 11.6 to 77.9 ± 13.1, p < .01) and increased mean arterial pressure (MAP) (74.1 ± 6.9 to 81.9 ± 6.6 mmHg, p < .01). In group II also, midodrine reduced HVPG (19.1 ± 4.1 to 17.0 ± 4.2) and HR (92.4 ± 13.7 to 84.6 ± 14.1) and increased MAP (85.4 ± 7.3 to 91.2 ± 7.6 mmHg), p < .01 for all. HVPG response was achieved in 3/30 (10%) in group I and 8/30 (26.7%) in group II. On logistic regression analysis, prerenal AKI (OR 11.04, 95% CI 1.83-66.18, p < .01) and increase in MAP (OR 1.22, 95% CI 1.03-1.43, p = .02) were independent predictors of response. Increase in MAP by 8.5 mmHg with midodrine had best cut-off with AUROC of .76 for response.
CONCLUSION: In decompensated cirrhosis and ACLF patients with contraindications to NSBB, midodrine is useful in decreasing HVPG. Dose of midodrine should be titrated to increase MAP atleast by 8.5 mmHg.
