Systemic lupus erythematosus (SLE) is a multiorgan-involved autoimmune disease, and it can overlap organ-specific autoimmune diseases such as autoimmune thyroid diseases, autoimmune hepatitis and inflammatory bowel disease. There may be some association between SLE and these autoimmune diseases, such as common immunological and genetic basis, but the pathogenic mechanism is still unclear. This review focuses on current knowledge regarding the prevalence and possible pathogenesis of SLE overlapping the above three autoimmune diseases.

OBJECTIVE:
To analyze the clinical features and prognosis in patients with primary Sjögren's syndrome (pSS) and autoimmune liver diseases (ALD).
METHODS:
A retrospective analysis of clinical manifestation and prognosis was performed in patients with ALD or without ALD during the three years (February 2014 to December 2017).
RESULTS:
Totally, 203 patients with pSS were included in this study, 68 patients had ALD (31 patients with autoimmune hepatitis, 37 patients with primary biliary cholangitis), while 135 patients did not have ALD. There were no differences between the two groups regarding age, gender, clinical manifestations, such as dry mouth, dry eyes, pain, fatigue, lymphadenopathy, glandular swelling, cutaneous involvement, lung involvement, and renal involvement, and the incidence rate of other autoimmune diseases, such as autoimmune thyroid disease, rheumatoid arthritis, and vasculitis. There were also no differences in the titer of antinuclear antibody (ANA), the positive rates of anti-Sjögren's syndrome A antibody (SSA), SSA52, and anti-Sjögren's syndrome B antibody (SSB), and at the levels of erythrocyte sedimentation rate and C-reactive protein between the two groups. Most importantly, the pSS patients with ALD had a shorter disease course, a higher positive rate of anti-mitochondrial M2 antibody (AMA-M2) and anti-centromere antibody, a higher level of IgG and IgM, a lower level of complement 3, and a decreased number of blood cells. They also had a higher level of liver related serum index, such as alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transferase, alkaline phosphatase and total bilirubin, direct bilirubin, indirect bilirubin, a higher incidence rate of liver cirrhosis, an increased death incident (the mortality was 13.24% in the pSS patients with ALD, while 2.96% in the controls, P=0.013), and a worse prognosis. Binary Logistic regression analysis revealed that liver cirrhosis, the EULAR Sjögren's syndrome disease activity index (ESSDAI) scores and the level of total bilirubin were the prognostic factors of mortality in the pSS patients with ALD. The survival curve was estimated by the Kaplan-Meier method. It demonstrated that the pSS patients with ALD had a lower survival rate when compared with the controls.
CONCLUSION
The patients with both pSS and ALD will suffer from a more severe disease and a higher death incident. We should pay more attention to these patients and provide a better symptomatic treatment for them during clinical practice.

3.Current epidemiology and clinical characteristics of autoimmune liver diseases in South Korea.
Clinical and Molecular Hepatology 2018;24(1):10-19
Autoimmune liver diseases including autoimmune hepatitis (AIH) and primary biliary cholangitis (PBC) are rare diseases. The aim of this review is to examine the epidemiology and clinical characteristics of AIH and PBC in South Korea. There were 4,085 patients registered as AIH in the Rare Intractable Disease Registry of Korea between 2009-2013, with a median age of 56 years and female-to male ratio of 6.4. The age-adjusted incidence and prevalence of AIH were 1.07/100,000/year and 4.82/100,000 persons, respectively. Among the patients, 1.1% underwent liver transplantation, and case fatality was 2.18%. Liver cirrhosis at diagnosis was accompanied in 23%; liver biopsy was performed in 75.2%, and prednisolone therapy or prednisolone and azathioprine combination therapy was done in 73% with a remission rate of 86%. There were 2,824 patients with PBC (≥20 years) registered in Korea between 2009-2013 with a median age of 57 years and female-to male ratio of 6.2. The age-adjusted incidence and prevalence of PBC were 0.86/100,000/year and 4.75/100,000 persons, respectively. Among the patients, 2.5% underwent liver transplantation, and case fatality was 2.2% with a 5-year transplantation-free survival of 95.4%. Ursodeoxycholic acid (UDCA) was prescribed in 90% of the patients with a UDCA inadequate response rate of 30%. In conclusion, AIH and PBC are rare but mostly treatable diseases if diagnosed in the early stages. However, scarce data, low awareness, delayed diagnosis and non-availability of 2nd line therapeutics are important issues to be solved. Therefore, governmental support for research and drug development and nationwide cooperative studies are warranted.

BACKGROUND/AIMS: Azathioprine (AZA) has been widely used in the therapy of inflammatory bowel disease (IBD) and autoimmune hepatitis (AIH). However, studies evaluating the adverse effects of AZA in these two diseases are lacking. The aim of this study was to compare the adverse effects of AZA in Korean IBD and AIH patients. METHODS: Patients with IBD or AIH who were treated with AZA at Keimyung University Dongsan Medical Center (Daegu, Korea) between January 2002 and March 2011 were enrolled. Their medical records were reviewed retrospectively in terms of clinical characteristics and adverse effects of AZA. RESULTS: A total of 139 IBD patients and 55 AIH patients were finally enrolled. Thirty IBD patients (21.6%) and eight AIH patients (14.5%) experienced adverse effects of AZA. In particular, the prevalence of leukopenia was significantly higher in the IBD group than in the AIH group (p=0.026). T474C mutation was observed in three of 10 patients who were assessed for thiopurine methyltransferase (TPMT) genotype. CONCLUSIONS: IBD patients are at increased risk for the adverse effects of AZA compared with AIH patients, of which leukopenia was the most commonly observed. Therefore, IBD patients receiving AZA therapy should be carefully monitored.
