This is the first report of long-term treatment of portal hypertension with PDE-5 inhibitors.
Variceal bleeding in liver cirrhosis due to autoimmune hepatitis.
Diagnosis of cirrhosis was done 20 years before start of treatment, so the decline in portal hypertension is probably attributable to PDE-5-Inhibitor-treatment rather than spontaneous improvement.
Improvement of portal hypertension was verified by invasive measurement of hepatovenous pressure gradient.
MRI and duplex sonographic images verified improvement in portal hemodynamics.
Liver cirrhosis was histologically confirmed 20 years prior to PDE-5-Inhibitor treatment.
Oral treatment with Tadalafil 5mg once daily.
Targeting the nitric oxide (NO)-cGMP-pathway in other diseases like pulmonary hypertension or erectile dysfunction.
Non-selective beta-blockers are the mainstay of medical therapy for portal hypertension in liver cirrhosis.
Experiences and lessons
Influencing the NO-pathway by the use of PDE-5 inhibitors may have long-term beneficial effects in compensated cirrhosis.
