[PMID: 37942733 PMCID: PMC10695339 DOI: 10.1097/meg.0000000000002661] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/21/2023] [Accepted: 09/21/2023] [Indexed: 11/10/2023]
Abstract
OBJECTIVE The objective of this study was to identify biochemical and clinical predictors of poor response (including incomplete response and non-response) to standard treatment in autoimmune hepatitis (AIH) patients. METHODS This study retrospectively collected clinical data from 297 patients who were first diagnosed with AIH in Beijing Ditan Hospital from 2010 to 2019. Finally, 149 patients were screened out. Risk factors were screened by univariate and multifactorial logistic regression. Then they were used to establish the nomogram. The ROC curve, calibration curve, decision curves analysis (DCA) and clinical impact curves (CIC) were used to evaluate the nomogram. RESULTS 149 patients were divided into two groups: the response group (n = 120, 80%) and the poor response group (n = 29, 20%). Multivariate logistic regression analysis found that IgG > 26.5 g/L (OR: 22.016; 95% CI: 4.677-103.640) in AIH patients increased the risk. In contrast, treatment response status was better in women (OR: 0.085; 95% CI: 0.015-0.497) aged >60 years (OR: 0.159; 95% CI: 0.045-0.564) with AST > 4.49 × ULN (OR: 0.066; 95% CI: 0.009-0.494). The C index (0.853) and the calibration curve show that the nomogram is well differentiated and calibrated; the DCA and CIC indicate that the model has good clinical benefits and implications. CONCLUSION The study found that male patients aged ≤ 60 years with IgG > 26.5 g/L and elevated AST ≤ 4.49 × ULN were more likely to have a non-response/incomplete response to standard treatment.

Hepatol Commun 2020; 4:1651-1663. [PMID: 33163835 PMCID: PMC7603536 DOI: 10.1002/hep4.1582] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/27/2020] [Revised: 06/30/2020] [Accepted: 07/08/2020] [Indexed: 12/17/2022] Open
Abstract
Drug-induced liver injury (DILI) sometimes presents with an autoimmune hepatitis-like phenotype (AI-DILI), and it is challenging to distinguish it from de novo autoimmune hepatitis (AIH). We conducted a study to identify autoantibodies unique to AI-DILI by profiling serum autoantibodies. Autoantibodies were quantified using an autoantigen array containing 94 autoantigens from four groups: AI-DILI (n = 65), DILI controls (n = 67), de novo AIH (n = 17), and healthy controls (HCs; n = 30). In 37 patients with AI-DILI, samples were also collected 6 months after presentation. AI-DILI and de novo AIH had similar anti-neutrophil antibody and anti-smooth muscle antibody prevalence. Compared to HCs, de novo AIH had an increase in many immunoglobulin G (IgG; 35 [46.1%]) and IgM (51 [70%]) autoantibodies, whereas AI-DILI had an increase of IgM (40 [54.8%]) but not IgG autoantibodies. DILI controls had a similar IgG and IgM profile compared to HCs. Comparing de novo AIH to AI-DILI identified 18 (23.7%) elevated IgG but only one (1.4%) IgM autoantibodies, indicating the unique IgG autoantibody profile in de novo AIH. Compared to DILI and HCs, increased IgM autoantibodies in AI-DILI and de novo AIH were common; however, AI-DILI induced by different drugs showed different frequencies of IgM autoantibodies, with nitrofurantoin-related AI-DILI showing a higher number of increased IgM autoantibodies. AI-DILI autoantibody levels at diagnosis and at 6 months showed a significant decline in 37 IgM autoantibodies. A model with highly correlated IgG and IgM was fitted into multivariate logistic regression and revealed an area under the curve of 0.87 (95% confidence interval, 0.79-0.95) to distinguish de novo AIH from AI-DILI. Conclusion: The unique IgG and IgM autoantibody signature appears to be a promising biomarker for distinguishing AI-DILI from de novo AIH.

Association of IL-10 and TGF-beta cytokine gene polymorphisms with autoimmune hepatitis. Clin Res Hepatol Gastroenterol 2019; 43:45-50. [PMID: 30143451 DOI: 10.1016/j.clinre.2018.07.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/09/2017] [Revised: 07/03/2018] [Accepted: 07/23/2018] [Indexed: 02/04/2023]
Abstract
BACKGROUND AND AIMS Autoimmune hepatitis is a chronic immune-mediated liver injury caused by dysregulated immune response to liver antigens. Genetic susceptibility is affected by multiple single nucleotide polymorphisms in immune-related genes. There are few reports on the association of TGF-β and IL-10 genetic variants with autoimmune hepatitis. METHODS Allele frequency and genotype status of IL-10 -1082, -819, -592 and TGF-β +869 and +915 polymorphisms were investigated in 57 unrelated patients with autoimmune hepatitis and 140 healthy controls by polymerase chain reaction with sequence-specific primers. RESULTS IL-10 -592 and -819 allele frequencies and genotypes were not associated with autoimmune hepatitis in our population, while IL-10 -1082 genotypes were. IL-10 -1082/-819/-592 "high-producing" haplotype GCC was significantly less frequent in patients. TGF-β +869 "high-producing" allele C and genotype CC were significantly more in autoimmune hepatitis, compared to controls; whereas, TGF-β +915 "low-producing" allele C and genotype CC were significantly more in autoimmune hepatitis compared to control. TGF-β +869/+915 haplotype TG was significantly less frequent in patients while CC haplotype was significantly more frequently observed in patients. CONCLUSION We identified a significant association between IL-10 -1082/-819 and TGF-β +869/+915 genotypes and haplotypes with autoimmune hepatitis in Iranians.

Abstract
Chronic hepatitis B involves different immune cells. The direct role of antibody-secreting B cells in the severity of chronic hepatitis B unclear. In this study, the number of plaque forming cells [PFC-(IgG, IgM, anti-HBc IgG, and anti-HBc IgM)], liver function tests (LFT) [alkaline phosphatase (ALP), alanine aminotransferase (ALT), and total serum bilirubin (TSB)], the levels of IL-10 in sera and in lymphocyte cultures, the number of CD4(+) and CD8(+) cells were measured in the peripheral blood of patients and in the controls. In addition, the hepatocytotoxic effect of anti-HBc and anti-HBe in vitro was studied. The largest number of PFCs was observed in the peripheral blood of patients with chronic hepatitis B. This was concomitant with a decrease in CD4(+) /CD8(+) ratio versus this ratio in asymptomatic HBV carriers and in healthy volunteers (P < 0.05). An increase in immunoglobulin (IgG and IgM) levels, anti-HBc IgG, and anti-HBc IgM levels and LFTs in peripheral blood of patients with chronic hepatitis B was seen. Anti-HBc induced hepatocytotoxicity in vitro. The expression of mRNA and protein for IL-10 production was observed at a significant level in culture of lymphocytes isolated from patients with chronic hepatitis B. In addition, a high level of IL-10 was found only in the sera of patients with chronic hepatitis B. It is concluded that the antibody-secreting B cells and the antibodies, which are produced, play an important role in the severity of chronic hepatitis B, which was related negatively with CD4(+) /CD8(+) ratio and positively with IL-10 expression.
