A 57-year-old male with a history of alcoholism presented to the emergency room with abdominal pain, jaundice, transaminitis, and hyperbilirubinemia. Due to the history of alcoholism, it was initially presumed that the patient had alcoholic hepatitis but further investigation revealed that he was recently started on sulfasalazine for the treatment of rheumatoid arthritis. Upon cessation of the drug, the patient's liver function tests significantly improved over a few days and eventually normalized within weeks...

INTRODUCTION: The number of children diagnosed with autism spectrum disorder (ASD) has been rapidly rising in the past decade. The etiology of this disorder, however, is largely unknown, although the environmental relative to the genetic contribution is substantial. We conducted a scoping review to comprehensively assess the current state of knowledge of the environmental factors present from preconception to early life associated with ASD, and to identify research gaps. METHODS: We searched electronic databases MEDLINE, PsycINFO and ERIC for articles on potential risk factors or protective factors from the physical and social environments associated with ASD and its subclassifications published between 1 January, 2003, and 12 July, 2013...

The neurologic manifestations of neonatal hyperbilirubinemia in the central nervous system (CNS) exhibit high variations in the severity and appearance of motor, auditory and cognitive symptoms, which is suggestive of a still unexplained selective topography of bilirubin-induced damage. By applying the organotypic brain culture (OBC: preserving in vitro the cellular complexity, connection and architecture of the in vivo brain) technique to study hyperbilirubinemia, we mapped the regional target of bilirubin-induced damage, demonstrated a multifactorial toxic action of bilirubin, and used this information to evaluate the efficacy of drugs applicable to newborns to protect the brain...

A two-year-old girl was admitted due to repeated yellowing of the skin and sclera for 2 years and had no other specific symptoms or signs. The use of phenobarbital could relieve the symptoms of jaundice. Multiple examinations showed increased indirect bilirubin levels, and the results of aminotransferases and liver imaging were normal. There was no evidence of hemolysis. The analysis of UGT1A1 gene in her family found that this child had double homozygous mutation of c.211G>A(G71R) and c.1456T>G(Y486D), which had been reported as the pathogenic mutation for Gilbert syndrome...

BACKGROUND: Neonatal hyperbilirubinemia is influenced by a wide variety of factors, one of which is hemolysis. Serious hyperbilirubinemia may lead to a kernicterus with detrimental neurologic sequelae. Patients suffering from hemolytic disease have a higher risk of developing kernicterus. Carbon monoxide (CO), a byproduct of hemolysis or heme degradation, was described by Sjöstrand in the 1960s. It is transported as carboxyhemoglobin (COHb) and exhaled through the lungs. We were interested in a potential correlation between COHb and total serum bilirubin (TSB) and the time course of both parameters...

Acute viral hepatitis is usually a self-limiting illness. However, it can lead to complications that can be life-threatening, such as acute liver failure. Glucose 6 phosphate dehydrogenase (G6PD) deficiency in the setting of acute viral hepatitis can lead to a massive hemolysis, manifesting as acute kidney injury and markedly raised bilirubin levels; although cases are rare. Here, we report such a case. The patient had a viral hepatitis E infection and presented with kidney injury requiring dialysis. Examination showed very high mixed hyperbilirubinemia due to massive intravascular hemolysis...

Gilbert's syndrome is derived from a polymorphism (TA repeat) in the hepatic UGT1A1 gene which results in decreased conjugation and increased levels of unconjugated bilirubin. Recently, we have shown that bilirubin binds directly to the fat burning nuclear peroxisome proliferator-activated receptor α (PPARα). Additionally, we have shown that serine 73 phosphorylation (Ser(P)(73)) of PPARα decreases activity by reducing its protein levels and transcriptional activity. The aim of this study was to determine if humanized mice with the Gilbert's polymorphism (HuUGT*28) have increased PPARα activation and reduced hepatic fat accumulation...

Jaundice due to unconjugated bilirubin is an everyday condition in the neonatal period because it results from the adaptation of bilirubin metabolism at this time of life. Hyperbilirubinemia has a potential neurotoxicity and although it most often resolves spontaneously, it can lead to acute and sometimes chronic encephalopathy. The latter condition is called kernicterus and induces severe and irreversible neurological sequelae. This rare complication is still reported in all countries throughout the world even if severe hyperbilirubinemia can be prevented and critical points points of failure in jaundice management are identified...

BACKGROUND: Gilbert syndrome (GS) is a common hereditary condition, characterized by intermittent unconjugated hyperbilirubinemia. In adults with type 2 diabetes and GS, a markedly lower prevalence of nephropathy was documented, suggesting a beneficial effect of hyperbilirubinemia. We investigated the prevalence of GS among individuals with type 1 diabetes mellitus (T1DM), and the prevalence of microalbuminuria. METHODS: The prevalence of GS was assessed in 401 (204 female) patients with T1DM, median age 21...

Various mutations in the genes encoding alpha spectrin (SPTA1) or beta spectrin (SPTB) are known to cause erythrocyte membrane disorders, sometimes associated with severe neonatal jaundice and anemia. We used a next-generation sequencing panel to evaluate 3 unrelated neonates who had puzzling cases of nonimmune hemolytic jaundice. In each case, we identified novel mutations in either SPTA1 or SPTB. Correlating erythrocyte morphology, clinical course, and computational analysis, we submit that each of the 3 variants is a probable pathogenic cause of the hereditary hemolytic conditions in these patients...

BACKGROUND: Six months of adjuvant chemotherapy is regarded as the standard of care for patients with stage III colon cancer. However, whether longer treatment can improve prognosis has not been fully investigated. We conducted a phase III study comparing 6 and 12 months of adjuvant capecitabine chemotherapy for stage III colon cancer, and report here the results of our preplanned safety analysis. METHODS: Patients aged 20-79 years with curatively resected stage III colon cancer were randomly assigned to receive 8 cycles (6 months) or 16 cycles (12 months) of capecitabine (2500 mg/m(2)/day on days 1-14 of each 21-day cycle)...

BACKGROUND: Patients with metastatic disease of the liver can have hyperbilirubinemia due to a number of reasons, including biliary obstruction. The purpose of this study was to analyze patient outcomes after percutaneous biliary drainage (PBD) catheter insertion in patients with extensive hepatic metastatic tumor burden. METHODS: Out of 746 PBD insertions, 44 patients (24 males, 20 females, mean age 57.4 years, range, 34-80 years) had metastatic malignancy with a hepatic tumor burden of greater than 20% parenchymal volume based on pre-procedure computed tomography (CT) or magnetic resonance imaging (MRI)...

Elevations in serum bilirubin during drug treatment may indicate global liver dysfunction and a high risk of liver failure. However, drugs also can increase serum bilirubin in the absence of hepatic injury by inhibiting specific enzymes/transporters. We constructed a mechanistic model of bilirubin disposition based on known functional polymorphisms in bilirubin metabolism/transport. Using physiologically-based pharmacokinetic model-predicted drug exposure and enzyme/transporter inhibition constants determined in vitro, our model correctly predicted indinavir-mediated hyperbilirubinemia in humans and rats...

BACKGROUND: Routine and timely determination of total serum bilirubin (TSB) remains a challenge in many resource-limited countries with substantial burden of severe neonatal hyperbilirubinemia. Limited evidence exists on the potential usefulness of transcutaneous bilirubin (TcB) to identify infants who may require phototherapy based on possible treatment criteria in such settings. OBJECTIVE: To compare the number of infants requiring phototherapy across different TSB criteria and determine the predictive performance of TcB under each criterion...

Hyperbilirubinemia is a common cause for irreversible neuronal influence in the brain of term newborns, while the feature of neurological symptoms associated with hyperbilirubinemia has not been well characterized yet. In the present study, we examined a total of 203 neonates suffering from hyperbilirubinemia with a bedside amplitude-integrated Electroencephalography (aEEG) device, in order to determine whether there is any special change in sleep-wake cycles (SWCs). Among these patients, 14 cases showed no recognizable SWCs with the total serum bilirubin (TSB) level at 483...

A 33-week gestation boy with Mediterranean glucose-6-phosphate dehydrogenase (G6PD) and a glutathione S-transferase Mu 1 null mutations (GSTM1*0/*0) developed prolonged indirect hyperbilirubinemia (PIH). He had no laboratory evidence of haemolysis or infection, and no exposure to oxidising agents. He has two full-term older brothers who have no history of neonatal hyperbilirubinemia. One brother, who was exclusively breast fed, has only Mediterranean G6PD and the other has only GSTM1*0/*0. The three boys have no mutation in the uridine diphosphate glucuronosyltransferase 1A1 gene...
