Background: Minimal hepatic encephalopathy (MHE) is the presence of neuropsychological abnormalities detectable by psychometric tests. Psychometric Hepatic Encephalopathy Score (PHES) is a gold standard test for the early diagnosis of MHE in cirrhotic patients. Aim: To standardize the PHES in a healthy Cameroonian population and to evaluate the prevalence of MHE among cirrhotic patients. Methods: This was a prospective, multicentric study from December 1st, 2018 to July 31st, 2019 in two groups: healthy volunteers and cirrhotic patients without clinical signs of hepatic encephalopathy. The results of the Number Connection Test-A (NCT-A), Number Connection Test-B (NCT-B), Serial Dotting Test (SDT), Line Tracing Test (LTT) were expressed in seconds and those of the Digit Symbol Test (DST) in points. Results: A total of 102 healthy volunteers (54 men, 48 women) and 50 cirrhotic patients (29 men, 31 women) were included. The mean age was 38.1 ± 12.55 years in healthy volunteers and 49.3±15.6 years in cirrhotic patients. The mean years of education level was 11.63 ± 4.20 years in healthy volunteers and 9.62±3,9 years in cirrhotic patients. The PHES of the healthy volunteer group was -0.08 ± 1.28 and the cut-off between normal and pathological values was set at −3 points. PHES of the cirrhotic patients was -7.66 ± 5.62 points and significantly lower than that of volunteers (p Conclusion: PHES cut-off value in Cameroonians is -3, with MHE prevalence of 74% among cirrhotic patients. |
