[PMID: 37393774 DOI: 10.1016/j.ajem.2023.06.042] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Revised: 06/09/2023] [Accepted: 06/22/2023] [Indexed: 07/04/2023] Open
Abstract
BACKGROUND Previous evidence demonstrated that several biomarkers involved in the pathological process of coagulation/hemostasis dysfunction, impairment of brain vascular integrity and inflammation are associated with hematoma expansion (HE) after intracerebral hemorrhage (ICH). We aimed to explore whether there were unreported laboratory biomarkers associated with HE that were readily and commonly available in clinical practice. METHODS We retrospectively analyzed consecutive acute ICH patients from 2012 to 2020 with admission laboratory tests and baseline and follow-up computed tomography (CT) scans. Univariate and multivariate regression analyses were used to evaluate associations between conventional laboratory indicators and HE. The results were verified in a prospective validation cohort. The relationship of candidate biomarker and 3-month outcomes was also investigated and mediation analysis was undertaken to determine causal associations among candidate biomarker, HE and outcome. RESULTS Of 734 ICH patients, 163 (22.2%) presented HE. Among the included laboratory indicators, higher direct bilirubin (DBil) was associated with HE (adjusted odds ratio [OR] of per 1.0 μmol/L change 1.082; 95% confidence interval [CI] 1.011-1.158). DBil >5.65 μmol/L was a predictor of HE in validation cohort. Higher DBil was also associated with poor 3-month outcomes. The mediation analysis indicated that the association of higher DBil and poor outcomes was partially mediated by HE. CONCLUSIONS DBil is a predictor of HE and poor 3-month outcomes after ICH. DBil's metabolic process and involvement in the pathological mechanism of HE are likely to contribute to the association between DBil and HE. Interventions targeting DBil to improve post-ICH prognosis may be meaningful and worthy of further exploration.

Teng J, Bohlin K, Nemeth A, Fischler B. Cholestasis after very preterm birth was associated with adverse neonatal outcomes but no significant long-term liver disease: A population-based study. Acta Paediatr 2021; 110:141-148. [PMID: 32524628 DOI: 10.1111/apa.15408] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/13/2020] [Revised: 05/09/2020] [Accepted: 06/04/2020] [Indexed: 12/26/2022]
Abstract
AIM To describe outcome linked to neonatal cholestasis in a defined cohort of very preterm infants. METHODS Population-based retrospective case-control study of preterm infants, gestational age <30 weeks, surviving for 28 days, in Stockholm County. Cholestasis was defined as conjugated bilirubin ≥30 μmol/L exceeding 20% of total level at least twice and graded as high if exceeding 100 μmol/L. Cholestatic cases were matched on gestational week with two non-cholestatic controls. RESULTS The incidence rate of cholestasis was 37/250 (14.8%), with increasing rates in lower gestational weeks. Perinatal factors associated with cholestasis were pre-eclampsia and being born small for gestational age. Cholestatic infants had three times more bronchopulmonary dysplasia and eight times more retinopathy of prematurity. The mortality was 13.5% in cholestatic infants versus 2.7% in controls (P = .040). All deceased cholestatic infants had high-grade cholestasis. No surviving infants developed chronic liver disease by 10 years of age. CONCLUSION Cholestasis was common in very preterm infants and linked to disease severity and adverse outcome. Cholestasis may be an independent risk factor for bronchopulmonary dysplasia and retinopathy of prematurity and more severe cholestasis associated with increased mortality. Cholestasis was not associated with chronic liver disease later in childhood.

Abstract
Bile acids (BAs) are produced by liver hepatocytes and were recently shown to exert functions additional to their well-known role in lipid digestion. As yet it is not known whether the mucosal-associated invariant T (MAIT) cells, which represent 10-15% of the hepatic T cell population, are affected by BAs. The focus of the present investigation was on the association of BA serum concentration with MAIT cell function and inflammatory parameters as well as on the relationship of these parameters to body weight. Blood samples from 41 normal weight and 41 overweight children of the Lifestyle Immune System Allergy (LISA) study were analyzed with respect to MAIT cell surface and activation markers [CD107a, CD137, CD69, interferon (IFN)-γ, tumor necrosis factor (TNF)-α] after Escherichia coli stimulation, mRNA expression of promyelocytic leukemia zinc finger protein (PLZF) and major histocompatibility complex class I-related gene protein (MR1), the inflammatory markers C-reactive protein (CRP), interleukin (IL)-8 and macrophage inflammatory protein (MIP)-1α as well as the concentrations of 13 conjugated and unconjugated BAs. Higher body weight was associated with reduced MAIT cell activation and expression of natural killer cell marker (NKp80) and chemokine receptor (CXCR3). BA concentrations were positively associated with the inflammatory parameters CRP, IL-8 and MIP-1α, but were negatively associated with the number of activated MAIT cells and the MAIT cell transcription factor PLZF. These relationships were exclusively found with conjugated BAs. BA-mediated inhibition of MAIT cell activation was confirmed in vitro. Thus, conjugated BAs have the capacity to modulate the balance between pro- and anti-inflammatory immune responses.

Abstract
Intestinal failure (IF)-associated liver disease (IFALD), as a major complication, contributes to significant morbidity in pediatric IF patients. However, the pathogenesis of IFALD is still uncertain. We here investigate the roles of bile acid (BA) dysmetabolism in the unclear pathogenesis of IFALD. It found that the histological evidence of pediatric IF patients exhibited liver injury, which was characterized by liver bile duct proliferation, inflammatory infiltration, hepatocyte apoptosis and different stages of fibrosis. The BA compositions were altered in serum and liver of pediatric IF patients, as reflected by a primary BA dominant composition. In IF patients, the serum FGF19 levels decreased significantly, and were conversely correlated with ileal inflammation grades (r = −0.50, p < 0.05). In ileum, the inflammation grades were inversely associated with farnesoid X receptor (FXR) expression (r = −0.55, p < 0.05). In liver, the expression of induction of the rate-limiting enzyme in bile salt synthesis, cytochrome P450 7a1 (CYP7A1) increased evidently. In conclusion, ileum inflammation decreases FXR expression corresponding to reduce serum FGF19 concentration, along with increased hepatic bile acid synthesis, leading to liver damages in IF patients.

Abstract
BACKGROUND & AIMS The pathogenesis of intestinal failure (IF) associated liver disease (IFALD) is uncertain, we therefore investigated the role of FGF19 and pro-inflammatory cytokines has on this disease state. METHODS Serum FGF19, IL-6 and, TNF-α were measured in 52 IF patients at median age 6.0 years (IQR 2.2-13) after 10 months (4.1-39) on parenteral nutrition (PN). Thirty-nine patients underwent liver biopsies. RESULTS In IF patients, FGF19 concentrations were lower and those of IL-6 and TNF-α higher compared to healthy matched controls (p ⩽ 0.001 for all). FGF19 concentrations were further decreased in patients without a remaining ileum [37 pg/ml (IQR 30-68) vs. 74 (35-135) p=0.028], and correlated with remaining ileum length (r = 0.333, p = 0.018) and markers of cholesterol synthesis (r = -0.552 to -0.643, p < 0.001). Patients with histological portal inflammation [30 pg/ml (28-45) vs. 48 (33-100), p = 0.019] or fibrosis [35 pg/ml (30-66) vs. 99 (38-163), p = 0.013] had lower serum FGF19 concentrations than others. FGF19 negatively correlated with portal inflammation grade (r = -0.442, p = 0.005), serum TNF-α (r = -0.318, p = 0.025), METAVIR fibrosis stage (r = -0.441, p = 0.005) and APRI (r = -0.328, p = 0.028). IL-6 was higher during PN [6 pg/ml (2-31)] than after weaning off PN [2 pg/ml (1-5), p = 0.009], correlated weakly with cholestasis grade (r = 0.328, p = 0.044), and tended to associate with histological cholestasis [n = 5, 5 pg/ml (5-267) vs. n=34, 2 pg/ml (1-7), p = 0.058]. CONCLUSIONS In pediatric onset of IF, total or partial loss of ileum decreases serum FGF19 concentration corresponding to hepatic inflammation and fibrosis, along with increased cholesterol synthesis. In contrast, serum IL-6 increases during PN and may associate with concurrent cholestasis. These data suggests that FGF19 may contribute to the pathogenesis of IFALD.

Protective Effects of Guava Pulp on Cholestatic Liver Injury. ISRN HEPATOLOGY 2013; 2013:601071. [PMID: 27335829 PMCID: PMC4890915 DOI: 10.1155/2013/601071] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/05/2013] [Accepted: 09/05/2013] [Indexed: 12/22/2022]
Abstract
Background. Cholestatic liver injury is a leading cause of chronic liver diseases involved with oxidative stress changes and inflammation; thus, antioxidant and anti-inflammation compound-rich guava may play a pivotal role in protecting against the cholestatic liver damages. Our aims for this study are to determine whether guava pulp (GP) has protective effects on cholestatic liver injury-induced mouse model and on interleukin-6 (IL-6) mediated proliferation of QBC939 cholangiocarcinoma cell line. Methods. Mice were induced to cholestatic liver damage by left and median bile duct ligation (LMBDL) surgery and then treated with GP. Plasma and liver samples were collected for biochemical and pathological assays. 5-Bromo-2'-deoxyuridine (BrdU) assay and Western blots were used to detect proliferation and gene expression in QBC939 cells, respectively. Results. Compared with LMBDL only group, in GP-treated mice, the levels of alanine aminotransferase (ALT) and bilirubin decreased, biliary epithelial cell proliferation and liver fibrogenesis were suppressed, Src/MEK/ERK1/2/c-Myc pathway and expressions of transforming growth factor β1(TGF-β1), tissue inhibitor of metalloproteinases TIMP), and procollagen 1α1(COL1α1) were downregulated significantly. Moreover, the GP extract reduced IL-6-enhanced QBC939 cell proliferation, p-ERK, and c-Myc expression as well. Conclusions. GP may provide a new perspective for the treatment of cholestatic liver injury.
