Systemic and pulmonary hemodynamics in patients with non-cirrhotic portal fibrosis (NCPF) is similar to compensated cirrhosis

Background: Non-cirrhotic portal fibrosis (NCPF) is an important cause of portal hypertension (PHT) and variceal bleeding, especially in the developing countries. While the hepatic parenchyma and liver functions are normal, the patho-anatomic defect in these patients is pre- and peri-sinusoidal in nature. Aim: To study the systemic and pulmonary hemodynamic alterations in patients with NCPF and compare them with compensated cirrhotic patients. Patients and methods: Patients with NCPF (n = 20, mean age 29.3 ± 9.8 year) and matched Child's A cirrhotic patients (n = 17, age 34.1 ± 9.8 year) who had bled in the past, underwent hemodynamic measurements using a balloon tipped catheter. Results: In NCPF patients, the hepatic venous pressure gradient (HVPG) was significantly lower than in the cirrhotic patients (4.9 ± 1.5 mmHg vs. 15.7 ± 4.5 mmHg; P < 0.01). NCPF patients had hyperdynamic circulation and peripheral vasodilatation comparable to cirrhotic patients; cardiac output (8.0 ± 1.2 l/min vs. 8.4 ± 1.9 l/min; P = 0.4), cardiac index (5.4 ± 0.8 l/min/m2 vs. 5.5 ± 1.9 l/min/m2; P = 0.86), mean arterial pressure (88.2 ± 14.1 mmHg vs. 89.9 ± 17.3 mmHg; P = 0.73), systemic vascular resistance (852.8 ± 204.3 dynes · s/cm5 vs. 854.1 ± 189.9 dynes · s/cm5; P = 0.98) and pulmonary vascular resistance (41.6 ± 18.1 dynes · s/cm5 vs. 41.3 ± 17.9 dynes · s/cm5; P = 0.95) were comparable in the two groups. Conclusions: NCPF associated portal hypertension leads to a hyperdynamic state with high cardiac index and low systemic and pulmonary vascular resistance comparable to compensated cirrhosis. These novel observations suggest a primary role of portal hypertension in the development of hyperdynamic state

Noncirrhotic portal fibrosis/idiopathic portal hypertension: APASL recommendations for diagnosis and treatment

The Asian Pacific Association for the Study of the Liver (APASL) Working Party on Portal Hypertension has developed consensus guidelines on the disease profile, diagnosis, and management of noncirrhotic portal fibrosis and idiopathic portal hypertension. The consensus statements, prepared and deliberated at length by the experts in this field, were presented at the annual meeting of the APASL at Kyoto in March 2007. This article includes the statements approved by the APASL along with brief backgrounds of various aspects of the disease
