ABSTRACT
BACKGROUND AND AIMS:
Autoimmune hepatitis (AIH) is a chronic, inflammatory disease of the liver with increasing prevalence. However, limited epidemiological data exist for the prevalence of AIH in the United States. We used a large database to describe the prevalence of AIH in the United States and the autoimmune diseases associated with it. APPROACH ANDRESULTS:
Data was collected from a commercial database (Explorys Inc., Cleveland, OH), an aggregate of Electronic Health Record data from 26 major integrated health care systems in the United States. We identified a cohort of patients with a diagnosis of AIH from April 2014 to April 2019 based on a Systemized Nomenclature of Medicine-Clinical Terms and calculated the prevalence of AIH. Of the 37,161,280 individuals active in the database from April 2014 to 2019, we identified 11,600 individuals with a diagnosis of AIH with an overall prevalence rate of 31.2/100,000. The prevalence of AIH was increased in females compared with males [odds ratio (OR)=3.21, P<0.0001], elderly (aged above 65 y) compared with adults (aged 18 to 65 y) and children (aged below 18 y) (OR=2.51, P<0.0001) and whites compared with African Americans, Asians, and Hispanics (OR=1.12, P<0.0001). Moreover, patients with AIH were more likely to have Sjögren syndrome, systemic lupus erythematosus, ulcerative colitis, celiac disease, rheumatoid arthritis, Crohn's disease, and autoimmune thyroiditis as compared with patients without AIH.CONCLUSIONS:
We found that the estimated prevalence of AIH in the United States is 31.2/100,000, which is comparable to the reported prevalence of AIH in Europe. We confirmed that AIH has a strong association with other autoimmune diseases studied in the literature.
