Current epidemiological status of causes of disease among patients with liver disease hospitalized in Department of Infectious Diseases in a large general hospital within the past 20 years / 中华肝脏病杂志

ABSTRACT

Objective@#To investigate the causes of disease among patients with liver disease hospitalized in Department of Infectious Diseases in our hospital and the changes in such causes within the past 20 years.@*Methods@#A retrospective analysis was performed for the clinical data of 7570 patients who were admitted to our hospital from January 1995 to December 2015. The chi-square test was used for the statistical analysis of constituent ratio.@*Results@#Of all 7570 patients with liver disease, 4930 (65.13%) had viral hepatitis, 332 (4.39%) had immune disease, 215 (2.84%) had drug-induced liver injury, 192 (2.54%) had fatty liver disease, 88 (1.16%) had schistosome-induced liver disease, 160 (2.11%) had inherited metabolic diseases, and 20 (0.13%) had vascular disease; 689 (9.1%) still had no clear cause of disease at discharge. The proportion of patients with viral hepatitis was 77.61% in the first 10 years and 59.19% in the last 10 years (P < 0.01). As for liver disease caused by hepatotropic virus, there were significant increases in the proportion of patients with hepatitis C or hepatitis E from the first to the last 10 years (hepatitis C: 2.24% vs 15.56%, P < 0.01; hepatitis E: 18.61% vs 23.07%, P < 0.05), while there were significant reductions in the proportion of patients with hepatitis B (68.14% vs 60.01%, P < 0.05) or hepatitis A (10.7% vs 1.36%, P < 0.05). The proportion of patients with immune diseases was 0.82% in the first 10 years and 6.08% in the last 10 years (P < 0.01). There were also certain changes in the proportion of patients with liver disease caused by other reasons.@*Conclusion@#There is a large proportion of patients with viral hepatitis among patients with liver disease hospitalized in Department of Infectious Diseases in a large general hospital, especially hepatitis B and E caused by hepatotropic virus. There is a certain change in the epidemiology of liver disease within the past 20 years, with a reduction in the proportion of patients with viral hepatitis and an increase in the proportion of patients with non-infectious liver diseases. There is a large proportion of patients with unknown causes of liver disease.
