RESUMO
OBJECTIVE: We aimed to analyze the relationship between non-alcoholic fatty liver and progressive fibrosis and serum 25-hydroxy vitamin D (25(OH)D) in patients with type 2 diabetes mellitus. METHODS: A total of 184 patients with T2DM who were hospitalized in the Department of Endocrinology of the ShiDong Clinical Hospital between January 2023 and June 2023 were selected. We compared review of anthropometric, biochemical, and inflammatory parameters and non-invasive scores between groups defined by ultrasound NAFLD severity grades.We determine the correlation between 25(OH)D and FLI and FIB-4 scores, respectively. RESULTS: Statistically significant differences were seen between BMI, WC, C-peptide levels, FPG, ALT, serum 25(OH)D, TC, HDL, lumbar spine bone density, FLI, and FIB-4 in different degrees of NAFLD. Multivariate logistic regression analysis showed that 25(OH)D (OR = 1.26, p = 0.001), age (OR = 0.93, P < 0.001) and BMI (OR = 1.04, p = 0.007) were independent predictors of NAFLD in patients with T2DM. CONCLUSIONS: This study revealed the correlation between serum 25(OH)D levels and NAFLD in patients with T2DM. We also demonstrated that serum 25(OH)D levels were negatively correlated with FLI/FIB-4 levels in patients with T2DM with NAFLD, suggesting that vitamin D deficiency may promote hepatic fibrosis progression in T2DM with NAFLD.

INTRODUCTION: This study aimed to investigate the role of immunocompetence in chronic hepatitis B (CHB) patients with normal alanine transaminase (ALT) levels and negative hepatitis B e antigen (HBeAg) in the risk assessments of the progression of liver fibrosis. METHODS: We collected the clinical data of 57 patients with CHB, with normal ALT levels and negative HBeAg from December 2020 to December 2022. With hepatitis B virus (HBV) DNA > 20 IU/mL and ALT ≤ 40 U/L, these patients had never undergone antiviral therapy. The levels of CD4+ , CD4+ CD25+ , CD8+ , and CD4+ CD25+ CD127LOW regulatory T cells (Tregs) in the patients were detected using flow cytometry; the liver stiffness measurement (LSM) values of the patients were detected using Fibroscan. RESULTS: There was a statistically significant difference between the levels of fibrosis-4 (FIB-4) and hepatitis B surface antigen (HBsAg) when the cutoff point was HBsAg ≥ 1500 (p < .001). FIB-4 was negatively correlated with HBsAg (R = -0.291, p = .028) and positively correlated with age (R = 0.787, p < .001). LSM was negatively correlated with Treg but this correlation was not statistically significant (p > .05). Findings based on the analysis using logistic regression were as follows: (i) age was the independent risk factor when FIB-4 was used as the indicator for assessing liver fibrosis; (ii) Treg was the independent risk factor when LSM was used as the indicator for assessing liver fibrosis. When Treg was used to predict liver fibrosis, the cutoff value, diagnostic efficacy, area under the receiver operating characteristic (ROC) curve, and p value of the ROC curve were 6.875, 0.641, 0.84, and .027, respectively. CONCLUSION: Age and Treg are independent risk factors for progressive liver fibrosis. The cutoff value of Treg > 6.81 indicates the need for timely antiviral treatment and can serve as an indicator for evaluating liver fibrosis.

BACKGROUND: The objective of this study is to retrospectively analyze the correlation between the thyroid hormones and nonalcoholic fatty liver disease (NAFLD) in type 2 diabetes mellitus (T2DM) patients with normal thyroid function. METHODS: Totally 586 T2DM patients with normal thyroid function participated in this research and were divided into T2DM without NAFLD (240 cases) group and T2DM with NAFLD (346 cases) group. The NAFLD fibrosis score (NFS) > 0.676 was defined as progressive liver fibrosis and used to categorize the patients into T2DM without progressive liver fibrosis group (493 cases) and T2DM with progressive liver fibrosis group (93 cases). RESULTS: The results indicated that the levels of free triiodothyronine (FT3), total triiodomethylamine (TT3) and FT3/free thyroxine ratio (FT3/FT4) were significantly higher while the FT4 level was lower in T2DM with NAFLD group than that in T2DM without NAFLD group (p < 0.05). The levels of FT3, FT4, TT3 and TT4 in patients with progressive liver fibrosis were significantly lower in patients with progressive liver fibrosis than that in patients without progressive liver fibrosis (p < 0.05). Logistic regression analysis showed a positive connection between FT3/FT4 ratio and NAFLD (p = 0.038), a negative relationship between FT4 level and NAFLD (p = 0.026), between the levels of FT4, TT3 and total thyroxine (TT4) and the risk of progressive hepatic fibrosis (p = 0.022, p = 0.007, p = 0.046). CONCLUSION: There is a certain correlation between thyroid hormone levels and NAFLD in T2DM patients, suggesting that the assessment of thyroid hormone levels in T2DM patients with normal thyroid function could be helpful in the prevention and treatment of NAFLD.

BACKGROUND: It is widely acknowledged that nonalcoholic fatty liver disease (NAFLD) and type 2 diabetes mellitus(T2DM) are all chronic metabolic diseases. The objective of this study is to retrospectively probe the association between the 25-hydroxyvitamin D (25-(OH)D) and NAFLD in type 2 diabetic patients. METHODS: Three hundred thirty-nine T2DM patients participated in this research and from November 2018 to September 2019 and were divided into simple T2DM group (108 cases) and T2DM with NAFLD group (231 cases) in conformity with abdominal ultrasound diagnosis. The NAFLD fibrosis score (NFS) ≥0.676 was defined as progressive liver fibrosis.231 T2DM with NAFLD patients were categorized into two subgroups: progressive liver fibrosis subgroup (48 cases) and without progressive liver fibrosis subgroup (183 cases). RESULTS: The prevalence of NAFLD by Abdominal ultrasonography was 68%.The results indicated that the levels of 25-(OH) D were significantly lower in T2DM with NAFLD group than that in simple T2DM group(P < 0.01). The levels of 25-(OH) D were significantly lower in progressive liver fibrosis subgroup than that in patients without progressive liver fibrosis and simple T2DM,and 25-(OH) D levels were lower in without progressive liver fibrosis subgroup than that in simple T2DM group(p < 0.01 or p < 0.05). Multivariate logistic regression analysis showed that levels of 25-(OH) D were negative correlation with risk of NAFLD and progressive liver fibrosis(p = 0.011ãp = 0.044,respectively). CONCLUSIONS: we could come to a conclusion that low levels of 25-(OH) D was a risk factor for NAFLD and progressive liver fibrosis in T2DM patients.

Biliary atresia (BA) is a rare cholangiopathy of infancy in which the bile ducts obliterate, leading to profound cholestasis and liver fibrosis. BA is hypothesized to be caused by a viral insult that leads to over-activation of the immune system. Patients with BA are surgically treated with a Kasai portoenterostomy (KPE), which aims to restore bile flow from the liver to the intestines. After KPE, progressive liver fibrosis is often observed in BA patients, even despite surgical success and clearance of their jaundice. The innate immune response is involved during the initial damage to the cholangiocytes and further differentiation of the adaptive immune response into a T-helper 1 cell (Th1) response. Multiple studies have shown that there is continuing elevation of involved cytokines that can lead to the progressive liver fibrosis. However, the mechanism by which the progressive injury occurs is not fully elucidated. Recently, matrix metalloproteinase-7 (MMP-7) has been investigated to be used as a biomarker to diagnose BA. MMPs are involved in extracellular matrix (ECM) turnover, but also have non-ECM related functions. The role of MMP-7 and other MMPs in liver fibrosis is just starting to be elucidated. Multiple studies have shown that serum MMP-7 measurements are able to accurately diagnose BA in a cohort of cholestatic patients while hepatic MMP-7 expression correlated with BA-related liver fibrosis. While the mechanism by which MMP-7 can be involved in the pathophysiology of BA is unclear, MMP-7 has been investigated in other fibrotic pathologies such as renal and idiopathic pulmonary fibrosis. MMP-7 is involved in Wnt/ß-catenin signaling, reducing cell-to-cell contact by shedding of E-cadherin, amplifying inflammation and fibrosis via osteopontin (OPN) and TNF-α while it also appears to play a role in induction of angiogenesis This review aims to describe the current understandings of the pathophysiology of BA. Subsequently, we describe how MMP-7 is involved in other pathologies, such as renal and pulmonary fibrosis. Then, we propose how MMP-7 can potentially be involved in BA. By doing this, we aim to describe the putative role of MMP-7 as a prognostic biomarker in BA and to provide possible new therapeutic and research targets that can be investigated in the future.
RESUMO
BACKGROUND AND AIM: Eradication of hepatitis C virus (HCV) with interferon (IFN)-based therapy has been reported to reduce all-cause mortality in patients with chronic HCV infection. However, the impact of HCV eradication on non-liver-related mortality and causes of death has not been sufficiently investigated in patients with progressive HCV-related fibrosis. METHODS: We enrolled 784 chronic HCV patients with progressive liver fibrosis (aspartate aminotransferase to platelet ratio index >1). Cause of death, incidence of hepatocellular carcinoma, and all-cause mortality including non-liver-related mortality were analyzed. RESULTS: Of these 784 patients, 170 achieved sustained virological response (SVR) (eradication of HCV) with IFN-based therapy (IFN-SVR), and 614 did not receive IFN-based therapy (non-IFN patients, chronic HCV infection). The median follow-up duration was 10.3 years. Two hundred seventy-three patients died during follow-up (liver-related death, n = 171; non-liver-related death, n = 102). The mortality rate from non-liver-related disease was 63.6% (7/11) in IFN-SVR patients and 36.3% (95/262) in non-IFN patients, respectively. In multivariate analysis, the eradication of HCV associated with not only hepatocellular carcinoma incidence (hazard ratio (HR), 0.162; 95% confidence interval (CI), 0.092-0.284), and all-cause mortality (HR, 0.094; 95% CI, 0.047-0.187), but non-liver-related mortality (HR, 0.286; 95% CI, 0.127-0.644) as well. CONCLUSIONS: Eradication of HCV reduced both liver-related and non-liver-related mortality in patients with progressive HCV-related fibrosis.
