Analysis of influencing factors on hepatic encephalopathy in patients with non-cirrhotic portal hypertension

Abstract

Objective: To investigate the incidence of hepatic encephalopathy (HE) in patients with non-cirrhotic portal hypertension (NCPH) and to explore its risk factors. Methods: The incidence rate of HE in 150 cases with NCPH was evaluated in two hospitals, and 188 cases of compensated cirrhosis patients were taken as control. Logistic regression was used to screen for independent risk factors for HE in patients with NCPH. Results: The incidence of overt hepatic encephalopathy (OHE) in patients with NCPH was not statistically significantly different from that in patients with cirrhosis (4.7% vs. 6.9%, P = 0.682). The incidence of mild hepatic encephalopathy (MHE) was significantly lower than that of cirrhosis patients (32.7% vs. 46.3%, P < 0.05). The presence of upper gastrointestinal bleeding, infection and portosystemic venous shunt were the main independent factors for HE in NCPH patients (OR > 1, P < 0.05). Conclusion: HE is one of the important complications of NCP, and may be influenced by factors such as upper gastrointestinal bleeding, infection and portosystemic venous shunt.
