BACKGROUND AND AIMS: Gilbert syndrome (GS) is characterized by unconjugated hyperbilirubinemia without liver disease or overt hemolysis and it is found in 3-10% of the general population. Inherited hyperbilirubinaemia is attributable to a reduced UGT1A1 activity. The UGT1A1 promoter (TA) repeats variants are documented of being involved in abnormally elevated bilirubin levels. The aim of the present study is to analyze the impact of UGT1A1 promoter variants on bilirubin levels in Romanian patients clinically supected with GS...

BACKGROUND: Although hemihepatectomy with total caudate lobectomy (hemiHx-tc) is essential for the surgical treatment of hilar cholangiocarcinoma, the advantage of an anterior approach for hemiHx-tc has not been fully discussed technically; the significance of an anterior approach without liver mobilization for preventing infectious complications also remains unknown. METHODS: The liver parenchyma transection-first approach (Hp-first) technique is an early transection of the hepatic parenchyma without mobilization of the liver that utilizes a modified liver-hanging maneuver to avoid damaging the future remnant liver...

PURPOSE OF REVIEW: Jaundice, the physical finding associated with hyperbilirubinemia, results when the liver is unable to properly metabolize or excrete bilirubin. The purpose of this review is to examine some of the most common causes of jaundice in adults, provide insight into the diagnostic evaluation of jaundice, and review information on the outcomes of patients with jaundice. RECENT FINDINGS: An elevated level of bilirubin almost always indicates the presence of an underlying disease state...

Jaundice in the newborn period can be physiologic and is often due to benign causes. Jaundice due to conjugated hyperbilirubinemia extending beyond the second week of life may be an early sign of several cholestatic or metabolic liver diseases, and it requires logical and timely analysis so that specific treatments can be initiated. Alpha-1 antitrypsin deficiency is the most common genetic cause of pediatric liver disease and transplantation, and it must be considered when evaluating cholestatic infants. Here, we present an unusual case of alpha-1 antitrypsin deficiency with severe infantile cholestasis and rapid decompensation in the first 4 months of life, where in-depth but timely diagnosis was crucial for the appropriate intervention to take place...

We experienced a case of a 19-year-old man with Gilbert syndrome with concomitant hereditary spherocytosis. The patient presented with moderate unconjugated hyperbilirubinemia, and inherited etiology was strongly suspected. The diagnosis of Gilbert syndrome was confirmed by the genetic analysis of the UGT1A1 gene, demonstrating UGT1A1*28 and compound heterozygote UGT1A1*6. In addition, since the laboratory findings and imaging studies revealed lysemia as well as gallstone and splenomegaly, a diagnosis of hereditary spherocytosis was made as a comorbidity...

PURPOSE: Increased bilirubin concentrations may be related to outcome, but this has not been well studied. We evaluated the relationship between total serum bilirubin levels and outcome in critically ill patients. MATERIALS AND METHODS: Data were analyzed from adult critically ill patients included in a 1-day international prevalence study after excluding those with an obvious underlying cause of hyperbilirubinemia. RESULTS: Serum bilirubin concentrations were >1 mg/dL in 2803 (31%) of 8973 patients, and these patients had higher mortality rates than patients with lower bilirubin concentrations (30% vs 21%, P<...

Gilbert's syndrome (GS) is associated with a mild unconjugated hyperbilirubinemia, increased circulating antioxidant capacity, and reduced cardiovascular disease (CVD) risk. The current study investigated whether mildly elevated circulating unconjugated bilirubin (UCB) is negatively associated with multiple thrombotic risk factors including platelet activity, hemostatic function, and inflammation in individuals with GS. Blood samples were collected from matched GS and control subjects (14 per group). Activation-dependent platelet surface marker expression of PAC-1 (binds to GPIIb/IIIa surface receptors on activated platelets) and CD62P (marker for P-selectin released from activated degranulated platelets) was assessed in adenosine diphosphate (ADP)-stimulated platelets using flow cytometry...

Gilbert syndrome (GS) is a frequent benign clinical condition, marked by intermittent unconjugated hyperbilirubinemia, mostly due to the polymorphism uridine diphosphate-glucuronosyltransferase 1A1*28 (UGT1A1*28). Hyperbilirubinemia has been reported in a GS patient undergoing hepatitis C treatment, and other UGT isoforms polymorphisms have been linked to worse outcomes in viral hepatitis. Yet, little is known to GS contributions' to the liver disease scenario. Our aim was to assess UGT1A1 genotypes' frequency in chronic hepatitis C (CHC) patients and correlate with total bilirubin (TB)...

In this issue of Acta Physiologica, Bakrania, et al., examined the effects of hyperbilirubinemia on the aging male heart under basal conditions and after ischemic injury (1) . Heart disease is a significant problem for the aging population in general and males in particular. Ischemic heart disease is a leading cause of global mortality for males and is responsible for one out of four deaths in males in the United States. Therefore, developing novel strategies to combat the development and progression of heart disease has the potential to save millions of lives a year...

Extracorporeal liver support can be classified into cell-free, artificial methods (artificial liver support, ALS) and cell-based bioartificial methods (bioartificial liver support, BLS). ALS improves biochemical parameters of liver failure by the simultaneous removal of protein-bound and water-soluble substances. Here, the MARS therapy belongs to the most studied methods with a proved beneficial effect on hepatic encephalopathy (HE), hepatorenal syndrome (HRS) or hyperbilirubinemia. However, a general survival advantage of any liver support for liver failure has not been shown yet and is restricted to meta-analyses or patient subgroups...

OBJECTIVE: Benign joint hypermobility syndrome refers to hypermobile individuals with musculoskeletal symptoms in the absence of any systemic rheumatic disease; its prevalence is approximately 0.5%. In animal studies, bilirubin has been shown to reduce fibrosis induced by bleomycin. It has been suggested that bilirubin leads to hypermobility that affects the structure or function of collagen. In addition, our observation is that hypermobility occurs more often in patients with indirect hyperbilirubinemia...

New Direct-acting Antiviral Agents (DAA)-based anti-HCV therapies currently provide extraordinary opportunities to cure patients. Drug-drug interactions are however a real challenge during treatment. In particular, in HIV-infected patients in cART, DAA choice is limited by such interactions, which can result both in reduced efficacy and toxicity. We report the case of a HIV-infected patient on cART with atazanavir/ritonavir/abacavir/lamivudine, who presented kidney and biliary lithiasis, the latter treated with endoscopic retrograde cholangiopancreatography and endoscopic biliary sphincterotomy, after beginning anti-HCV treatment with daclatasvir/sofosbuvir/ribavirin...

REVIEW
Masashi Takano, Toru Sugiyama
Mutations in the UGT1A1 gene have been implicated in Gilbert syndrome, which shows mild hyperbilirubinemia, and a more aggressive childhood subtype, Crigler-Najjar syndrome. To date, more than 100 variants have been found in the UGT1A1 gene. Among them, UGT1A1*28 and UGT1A1*6 have been reported to be associated with severe toxicities in patients treated with irinotecan-based chemotherapy by increasing the dose of SN-38 (7-ethyl-10-hydroxycamptothecin), an active form of irinotecan. Many association studies and meta-analyses have demonstrated the contribution of UGT1A1*28 and UGT1A1*6 polymorphisms to the toxicities caused by irinotecan-based therapy...

BACKGROUND: Intravenous ribavirin has been reported to be an effective treatment for haemorrhagic fever with renal syndrome (HFRS) caused by Hantaan virus in Asia. However, its therapeutic benefits for HFRS caused by Puumala virus (PUUV) in Europe are still unknown. METHODS: A randomized, open-label study of efficacy and safety of intravenous ribavirin in the treatment of HFRS was conducted in the European part of Russia. Seventy-three patients with suspected HFRS within 4 d of the onset of the disease were randomized to receive either intravenous ribavirin (33 mg/kg, followed by 16 mg/kg given every 6 h for 4 d and by 8 mg/kg given every 8 h for 3 d) plus standard therapy (n = 37) or standard therapy alone (n = 36)...

Hyperbilirubinemia is a common finding in individuals with a history of substance abuse. Although this may indicate a serious disorder of liver function, this is not always the case. An understanding of bilirubin formation, metabolism, and transport can provide a helpful approach to dealing with these patients. This is typified by studies of patients treated with the antiretroviral drug atazanavir. Atazanavir has been associated with hyperbilirubinemia in as many as one-third of individuals for whom it has been prescribed, evoking concerns of hepatotoxicity...

Regorafenib has shown survival benefits in metastatic colorectal cancer patients who were exacerbated after all standard therapies. Some patients, however, exhibit severe adverse events (AEs) resulting in treatment discontinuation. Therefore, the selection of patients likely to benefit from regorafenib is crucial. Twenty patients were treated with regorafenib for metastatic colorectal cancer; 122 plasma samples were taken from 16 of these patients for monitoring of circulating tumor DNA (ctDNA) in the blood...

Importance. As Rivaroxaban has increased in popularity, it has been accompanied with a growing body of evidence displaying its ability to cause drug induced liver injury (DILI). Observation. A 74-year-old Caucasian female developed Rivaroxaban DILI two weeks after finishing a 14-day course. The patient was symptomatic and jaundiced with elevated transaminases and hyperbilirubinemia with normal lab values two months priorly. Liver biopsies showed mixed inflammatory infiltrate of lymphocytes, neutrophils and eosinophils, rare necrotic hepatocytes, and canalicular and intrahepatocellular cholestasis, all of which are consistent with DILI...

Hyperbilirubinemia is a pathological condition, very often indicative of underlying liver condition that is characterized by excessive accumulation of conjugated or unconjugated bilirubin in sinusoidal blood. In literature there are several indications associating the inhibition of the basolateral hepatic transporters Organic anion transporting polypeptide 1B1 and 1B3 (OATP1B1 and 1B3) with hyperbilirubinemia. In this article, we present a curated human hyperbilirubinemia dataset and the respective OATP1B1 and 1B3 inhibition predictions obtained from an effort to generate a classification model for hyperbilirubinemia...
