Establishment and validation of an adherence prediction system for lifestyle interventions in non-alcoholic fatty liver disease.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease worldwide, affecting about 1/4th of the global population and causing a huge global economic burden. To date, no drugs have been approved for the treatment of NAFLD, making the correction of unhealthy lifestyles the principle method of treatment. Identifying patients with poor adherence to lifestyle correction and attempting to improve their adherence are therefore very important. AIM: To develop and validate a scale that can rapidly assess the adherence of patients with NAFLD to lifestyle interventions. METHODS: The Exercise and Diet Adherence Scale (EDAS) was designed based on compilation using the Delphi method, and its reliability was subsequently evaluated. Demographic and laboratory indicators were measured, and patients completed the EDAS questionnaire at baseline and after 6 months. The efficacy of the EDAS was evaluated in the initial cohort. Subsequently, the efficacy of the EDAS was internally verified in a validation cohort. RESULTS: The EDAS consisted of 33 items in six dimensions, with a total of 165 points. Total EDAS score correlated significantly with daily number of exercise and daily reduction in calorie intake (P < 0.05 each), but not with overall weight loss. A total score of 116 was excellent in predicting adherence to daily reduction in calorie intake (> 500 kacl/d), (sensitivity/specificity was 100.0%/75.8%), while patients score below 97 could nearly rule out the possibility of daily exercise (sensitivity/specificity was 89.5%/44.4%). Total EDAS scores ≥ 116, 97-115, and < 97 points were indicative of good, average, and poor adherence, respectively, to diet and exercise recommendations. CONCLUSION: The EDAS can reliably assess the adherence of patients with NAFLD to lifestyle interventions and have clinical application in this population.

Direct-acting antivirals failed to reduce the incidence of hepatocellular carcinoma occurrence in hepatitis C virus associated cirrhosis: A real-world study.

BACKGROUND: Direct-acting antivirals (DAAs) revolutionized the treatment of chronic hepatitis C virus (HCV)-associated disease achieving high rates of sustained virological response (SVR). However, whether DAAs can reduce the occurrence of hepatocellular carcinoma (HCC) in patients with HCV-associated cirrhosis who are at high risk have not been concluded. AIM: To investigate the effect of DAAs on the occurrence of HCC in patients with HCV-associated cirrhosis after achieving SVR. METHODS: Of 427 inpatients with HCV-associated cirrhosis were enrolled in Tianjin Second People's Hospital from January 2014 to April 2020. 118 patients weren't received antiviral treatment with any reasons named non-antiviral treatment group, and 236 patients obtained from the 309 DAAs treatment patients according to the propensity score matching named DAAs treatment group. Demographic information and laboratory data were collected from baseline and the following up. Kaplan-Meier curve and Log-Rank test were used to compare the incidence and cumulative incidence of HCC between the two groups. Cox proportional risk regression was used to re-evaluate the risk factors for HCC. RESULTS: HCC incidence was 4.68/100PY (95%CI, 3.09-6.81) in the DAAs treatment group, while it was 3.00/100PY (95%CI, 1.50-5.37) in the non-antiviral treatment group, and the relative risk was 1.82 (95%CI, 0.93-3.53, P > 0.05). The incidence of HCC at 12, 24, 36 and 48 months was 3.39%, 6.36%, 8.47% and 10.17% in the DAAs treatment group, and it was 0%, 0%, 3.39% and 9.32% in the non-antiviral treatment group, respectively. Age > 58 [hazard ratio (HR) = 1.089; 95%CI, 1.033-1.147; P = 0.002] and liver stiffness measurement > 27.85 kPa (HR = 1.043; 95%CI, 1.022-1.065; P = 0.000) were risk factors for HCC in all patients (n = 427), and DAAs treatment didn't show protective efficacy. CONCLUSION: DAAs treatment seems failed to reduce the incidence of HCC occurrence in HCV-associated cirrhosis in 48 months, and even increased the incidence of HCC in 36 months.
