Beneficial long term effect of a phosphodiesterase-5-inhibitor in cirrhotic portal hypertension:A case report with 8 years follow-up

引用

World Journal of Gastroenterology 2018年第3期24卷 438-444页

作者： Peter Deibert Adhara lazaro Zoran Stankovic Denise Schaffner Martin Rossle Wolfgang Kreisel Faculty of Medicine Institute for Exercise and Occupational MedicineDepartment of MedicineUniversity HospitalFreiburg 79106Germany Inselspital Interventional and Pediatric RadiologyInstitute of DiagnosticUniversity of BernBern 3010Switzerland Department of Pharmaceutical Biology and Biotechnology University of FreiburgFreiburg 79106Germany Private Praxis PraxiszentrumFreiburg 79104Germany Faculty of Medicine Endocrinology and Infectious DiseasesDepartment of GastroenterologyHepatologyUniversity HospitalFreiburg 79106Germany

Non-selective beta-blockers are the mainstay of medical therapy for portal hypertension in liver cirrhosis. Inhibitors of phosphodiesterase-5(PDE-5-inhibitors) reduce portal pressure in the acute setting by > 10% which may suggest a long-term beneficial effect. Currently, there is no available data on long-term treatment of portal hypertension with PDE-5-inhibitors. This case of a patient with liver cirrhosis secondary to autoimmune liver disease with episodes of bleeding from esophageal varices is the first documented case in which a treatment with a PDE-5-inhibitor for eight years was monitored. In the acute setting, the PDE-5-inhibitor Vardenafil lowered portal pressure by 13%. The portal blood flow increased by 28% based onDoppler sonography and by 16% using MRI technique. As maintenance medication the PDE-5-inhibitor Tadalafil was used for eight consecutive years with comparable effects on portal pressure and portal blood flow. There were no recurrence of bleeding and no formation of new varices. Influencing the NO-pathway by the use of PDE-5 inhibitors may have long-term beneficial effects in compensated cirrhosis.
