Should I continue nadolol in my patient with cirrhosis and refractory ascites?

Under certain circumstances, you may need to! Although nonselective beta blockers (NSBBs), such as nadolol and propranolol, have been the cornerstone of medical treatment of portal hypertension in preventing variceal bleeding in patients with cirrhosis for decades, recent reports of their association with worsening survival, increased risk of hepatorenal syndrome and acute kidney injury in patients with refractory ascites or spontaneous bacterial peritonitis [SBP]) 1,2 have added controversy to their routine use in end-stage cirrhosis.

This is because patients with end-stage cirrhosis may be highly dependent on their cardiac output (particularly the heart rate) in maintaining an adequate arterial blood pressure 3-5 and the negative inotropic and chronotropic effects of NSBBs blunt this compensatory mechanism. The result is a drop in the cardiac output that may be particularly significant in the presence of conditions already associated with hypotension, such as sepsis, spontaneous bacterial peritonitis (SBP), or hemorrhage, further increasing the risk of renal hypoperfusion and hepatorenal syndrome.3

Although 2 meta-analysis studies failed to find an association between NSBBs and increased mortality among patients with cirrhosis and ascites, 6,7 serious concerns over the adverse effects of these drugs in at least a subset of patients has not waned.  Some have recommended reducing NSBB dose or discontinuing treatment in patients with refractory ascites or SBP and any of the following parameters: 4

  • Systolic blood pressure <90 mmHg
  • Serum creatinine >1.5 mg/dL
  • Hyponatremia <130 mmol/L

Similar recommendations were made by a 2015 consensus conference on individualizing the care of patients with portal hypertension.

In the absence of randomized-controlled studies, it seems prudent to proceed with more caution when using NSBBs in patients with end-stage cirrhosis and watch closely for any signs of hypotension or renal function deterioration.
