Multidrug Resistance-Associated Protein 2 Deficiency Aggravates Estrogen-Induced Impairment of Bile Acid Metabolomics in Rats.

Front Physiol 2022 21;13:859294. Epub 2022 Mar 21.

Department of Pharmacology, Faculty of Medicine in Hradec Kralove, Charles University, Hradec Kralove, Czechia.

Multidrug resistance-associated protein 2 (Mrp2) mediates biliary secretion of anionic endobiotics and xenobiotics. Genetic alteration of Mrp2 leads to conjugated hyperbilirubinemia and predisposes to the development of intrahepatic cholestasis of pregnancy (ICP), characterized by increased plasma bile acids (BAs) due to mechanisms that are incompletely understood. Therefore, this study aimed to characterize BA metabolomics during experimental Mrp2 deficiency and ICP. Read More

Abnormal liver enzymes: A review for clinicians.

World J Hepatol 2021 Nov;13(11):1688-1698

Department of Medicine, Texas A&M University, College Station, TX 77843, United States.

Liver biochemical tests are some of the most commonly ordered routine tests in the inpatient and outpatient setting, especially with the automatization of testing in this technological era. These tests include aminotransferases, alkaline phosphatase, gamma-glutamyl transferase, bilirubin, albumin, prothrombin time and international normalized ratio (INR). Abnormal liver biochemical tests can be categorized based on the pattern and the magnitude of aminotransferases elevation. Read More

[Gilbert's syndrome: hyperbilirubinemia enemy or friend].

Zhonghua Gan Zang Bing Za Zhi 2021 Oct;29(10):1024-1027

Department of Elderly Gastroenterology, The First Affiliated Hospital of China Medical University, Shenyang 110001, China.

Gilbert's syndrome is a kind of benign inherited disease of bilirubin binding disorder, mainly due to the homozygous polymorphism A(TA)7TAA in the promoter of the gene for uridine diphosphate -glucuronosyltransferase 1A1 (UGT1A1), which is a TA insertion into the promoter, designated as UGT1A1*28, with UGT activity reduction to 30% of the normal value. Therefore, circulating fat-soluble unconjugated bilirubin cannot be converted into water-soluble conjugated bilirubin, leading to unconjugated hyperbilirubinemia. Bilirubin has a strong affinity for erythrocyte phospholipids, which interferes with membrane composition and dynamics, resulting in increased erythrocytes fragility, easy rupture, and gradual shortening of survival time.

Double paternal uniparental isodisomy 7 and 15 presenting with Beckwith-Wiedemann spectrum features.

Cold Spring Harb Mol Case Stud 2021 12 9;7(6). Epub 2021 Dec 9.

Department of Medical Genetics, Haukeland University Hospital, 5021 Bergen, Norway.

Here we describe for the first time double paternal uniparental isodisomy (iUPD) 7 and 15 in a baby boy with features in the Beckwith-Wiedemann syndrome spectrum (BWSp) (placentomegaly, hyperinsulinism, enlarged viscera, hemangiomas, and earlobe creases) in addition to conjugated hyperbilirubinemia. His phenotype was also reminiscent of genome-wide paternal uniparental isodisomy. We discuss the most likely origin of the UPDs: a maternal double monosomy 7 and 15 rescued by duplication of the paternal chromosomes after fertilization. Read More

Boehringer Ingelheim Pharmaceuticals Inc., Ridgefield, CT, USA.

New molecular entities (NMEs) are evaluated using a rigorous set of in vitro and in vivo studies to assess their safety and suitability for testing in humans. Regulatory health authorities require that therapeutic and supratherapeutic doses be administered, by the intended route of administration, to two nonclinical species prior to human testing. The purpose of these studies is to identify potential target organ toxicity and to determine if the effects are reversible. Read More

Extracorporeal Albumin Dialysis in Liver Failure with MARS and SPAD: A Randomized Crossover Trial.

Blood Purif 2022 17;51(3):243-250. Epub 2021 Jun 17.

Département d'Anesthésie-Réanimation, Hôpital de la Croix-Rousse, Hospices Civils de Lyon, Lyon, France.

Introduction: Liver failure is associated with hepatic and extrahepatic organ failure leading to a high short-term mortality rate. Extracorporeal albumin dialysis (ECAD) aims to reduce albumin-bound toxins accumulated during liver failure. ECAD detoxifies blood using albumin dialysis through an artificial semipermeable membrane with recirculation (molecular adsorbent recirculating system, MARS) or without (single-pass albumin dialysis, SPAD).

Yinzhihuang Oral Liquid Ameliorates Hyperbilirubinemia Induced by δ-Aminolevulinic Acid and Novobiocin in Neonatal Rats.

Chem Biodivers 2021 Aug 22;18(8):e2100222. Epub 2021 Jun 22.

School of Pharmaceutical Science and Technology, Tianjin University, 92 Weijin Road, Nankai District, Tianjin, 300072, P. R. China.

Yinzhihuang oral liquid (YZH) is a traditional Chinese medicine that has been widely used in Asia to prevent and treat neonatal hyperbilirubinemia, but the published preclinical studies on its anti-hyperbilirubinemia effect are conducted in adult animals, partly due to the lack of preclinical neonatal hyperbilirubinemia animal models. In the present study, we tested six reagents to induce hyperbilirubinemia in neonatal rats, and established two appropriate neonatal hyperbilirubinemia rat models by subcutaneous injection of δ-Aminolevulinic acid (ALA, 200 mg/kg) or novobiocin (NOVO, 200 mg/kg). Oral treatment of YZH (80, 160 and 320 mg/kg) significantly decreased serum conjugated bilirubin levels in ALA-treated neonatal rats and serum unconjugated bilirubin levels in NOVO-treated neonatal rats, respectively.
