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

Chem Biodivers 2021 Jun 3. Epub 2021 Jun 3.

Tianjin University, School of Chemical Engineering and Technology, State Key Laboratory of Chemical, Tianjin University, 92 Weijin Road, Nankai District, Tianjin, 300072, Tianjin, 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 tried 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.

Hemolysis due to Alpha-Hemolytic Enterococcus Urinary Infection: A Rare Cause of Early and Severe Unconjugated Hyperbilirubinemia in a Neonate.

J Pediatr Intensive Care 2021 Mar 23;10(1):75-78. Epub 2020 Apr 23.

Division of Neonatology, Department of Pediatrics, Izmir Katip Celebi University Ataturk Training and Research Hospital, Izmir, Turkey.

The reason for reporting this case is to remind that some microorganisms may cause hemolysis leading to early and severe hyperbilirubinemia by secreting hemolysin in cases; where bilirubin levels cannot be successfully decreased despite effective phototherapy, intravenous immunoglobulin, and even exchange transfusion, or in cases of increased rebound bilirubin (although urinary tract infection is associated with increased conjugated bilirubin fraction and prolonged jaundice). The most common causes of hemolysis are ABO/Rh incompatibility and enzyme deficiencies such as glucose-6-phosphate dehydrogenase (G6PDH), pyruvate kinase (PK), and galactose-1-phosphate uridyltransferase (GALT). Our patient was a male infant, weighing 3,160 g, at 38 + 4 gestational week; he was referred to our unit with total bilirubin level of 14. Read More

Prediction of Drug-Induced Hyperbilirubinemia by In Vitro Testing.

Pharmaceutics 2020 Aug 11;12(8). Epub 2020 Aug 11.

Solvo Biotechnology, Science Park, Building B1, 4-20 Irinyi József utca, H-1117 Budapest, Hungary.

Bilirubin, the end product of heme catabolism, is produced continuously in the body and may reach toxic levels if accumulates in the serum and tissues; therefore, a highly efficient mechanism evolved for its disposition. Normally, unconjugated bilirubin enters hepatocytes through the uptake transporters organic anion transporting polypeptide (OATP) 1B1 and 1B3, undergoes glucuronidation by the Phase II enzyme UDP glucuronosyltransferase 1A1 (UGT1A1), and conjugated forms are excreted into the bile by the canalicular export pump multidrug resistance protein 2 (MRP2). Any remaining conjugated bilirubin is transported back to the blood by MRP3 and passed on for uptake and excretion by downstream hepatocytes or the kidney. Read More

Elucidation of OATP1B1 and 1B3 transporter function using transgenic rodent models and commonly known single nucleotide polymorphisms.

Toxicol Appl Pharmacol 2020 07 11;399:115039. Epub 2020 May 11.

Department of Pharmacology, Toxicology and Therapeutics, School of Medicine, University of Kansas, Kansas City, KS, United States of America.

The clearance of many drugs from the blood into the liver, such as the statins, is dependent on the organic anion transporting polypeptides (OATPs). Patients with *5 and *15 polymorphisms of OATP1B1 remove less of the statin as it traverses the liver and thus more reaches the rest of the body, including the skeletal muscle where it can cause myalgia, myopathy, and rhabdomyolysis. OATP1B1 polymorphisms also affect the pharmacokinetics of anticancer drugs (methotrexate, taxanes, and doxorubicin) and numerous anti-hypertensive drugs. Read More
