Efficacy of ursodeoxycholic acid in the prevention and treatment of COVID-19 in patients with chronic hepatitis B
Objective To investigate the potential effect of ursodeoxycholic acid(UDCA)in the prevention and treatment of COVID-19 in patients with chronic hepatitis B.Methods Clinical data were collected from 324 patients with chronic hepatitis B who were treated in Beijing Ditan Hospital,Capital Medical University,from January to December 2022,and according to whether UDCA was administered,they were divided into UDCA group and control group.The propensity score matching(PSM)method was used to balance the confounding factors such as age,sex,and chronic complications,and the two groups were compared in terms of SARS-CoV-2 infection rate,symptoms,and recovery time after COVID-19.The two groups were also compared in terms of related laboratory markers(white blood cell count[WBC],hemoglobin[Hb],platelet count[PLT],alanine aminotransferase[ALT],aspartate aminotransferase[AST],albumin[Alb],alkaline phosphatase[ALP],total bilirubin[TBil],triglyceride[TG],and total cholesterol[TC]),vaccination,and the incidence rate of liver disease symptoms after COVID-19.The independent-samples t test was used for comparison of normally distributed continuous data between two groups,and the Mann-Whitney U test was used for comparison of data with skewed distribution between the two groups;the chi-square test and the continuously corrected chi-square test were used for comparison of categorical data between two groups.The binary Logistic regression model was used for univariate and multivariate analyses to investigate the influencing factors for COVID-19 after matching.Results There were 87 patients in the UDCA group and 237 patients in the control group,and after PSM,there were 78 patients in the UDCA group and 137 patients in the control group,with good balance between the two groups.There was a significant difference in SARS-CoV-2 infection rate between the UDCA group and the control group[82.1%(64/78)vs 95.6%(131/137),χ2=10.847,P=0.001].After COVID-19,compared with the control group,the UDCA group had a significantly lower proportion of the patients with chill(10.9%vs 38.9%,χ2=16.124,P<0.001)and cough(56.3%vs 74.8%,χ2=6.889,P=0.009).There was a significant difference between the UDCA group and the control group in the proportion of the patients with a recovery time of≤7 days after COVID-19(79.7%vs 61.1%,χ2=6.760,P=0.009).Both univariate and multivariate logistic regression analyses showed that UDCA was an independent influencing factor for COVID-19(odds ratio=0.21 and 0.17,both P<0.05).Conclusion UDCA is an protective factor against COVID-19 in patients with chronic hepatitis B and can alleviate related symptoms to some extent and shorten the recovery time,and therefore,it has an important value in the prevention and treatment of COVID-19.
