TY - JOUR. T1 - Transcutaneous bilirubin in predicting hyperbilirubinemia in term neonates. AU - Bhat, Y Ramesh. AU - Rao, Amitha. PY - 2008/2. Y1 - 2008/2. N2 - OBJECTIVE: To assess the utility of 24 and 48 hours transcutaneous bilirubin (TcB) index for predicting subsequent significant hyperbilirubinemia in healthy term neonates.METHODS: TcB indices were obtained for healthy, breastfed, term AGA newborns at 24 +/- 2, 48 +/- 2 and subsequently at intervals of 24 hours. Neonates with illness, on treatment and positive Direct Coombs test were excluded. Serum bilirubin levels were obtained whenever indicated. Neonates having serum bilirubin , or = 17 mg/dL were considered as significant hyperbilirubinemia. The 24 and 48 hour TcB indices, as risk predictors for such hyperbilirubinemia were determined.RESULTS: Study included 461 healthy term neonates. The mean birth weight was 2949 (+/- 390) gm and mean gestation of 38.6 (+/- 1.1) weeks. Eight one (17.6%) had significant hyperbilirubinemia. Of 461, ...
Hyperbilirubinemia and Jaundice What is hyperbilirubinemia? Hyperbilirubinemia is a condition in which there is too much bilirubin in the blood. When red blood cells break down, a substance called bilirubin is formed. Babies are not easily able to get rid of the bilirubin and it can build up in the blood and other tissues and fluids of the babys body. This is called hyperbilirubinemia. Because bilirubin has a pigment or coloring, it causes a yellowing of the babys skin and tissues. This is called jaun...
Three small studies, enrolling a total of 170 infants, were eligible for inclusion in this review. None blinded intervention or outcome assessment. In all three studies some patients were excluded after randomization. Metalloporphyrin-treated infants appeared to have short-term benefits compared to controls, including a lower maximum plasma bilirubin level in one study, a lower frequency of severe hyperbilirubinemia in one study, a decreased need for phototherapy, fewer plasma bilirubin measurements and a shorter duration of hospitalization. None of the enrolled infants required an exchange transfusion in the two studies that described this outcome. None of the studies reported on neonatal kernicterus, death, long-term neurodevelopmental outcomes or iron deficiency anemia. Though a small number of metalloporphyrin-treated as well as control infants developed a photosensitivity rash, the trials were too small to rule out an increase in the risk of photosensitivity or other adverse effects from ...

ABR measurements reveal substantial hearing loss in Gunn rats within 18 h of exposure to high bilirubin. Extracellular multi-electrode array recordings showed impaired synaptic transmission through the MNTB in vitro. Whole-cell patch-clamp recordings from MNTB neurons in hyperbilirubinaemic rats confirmed that their electrophysiological properties were essentially unchanged from control animals. However, stimulation of the trapezoid body was unable to elicit large amplitude calyceal EPSCs in MNTB neurons of hyperbilirubinaemic Gunn rats. Multi-photon imaging of anterogradely labelled calyceal terminals revealed dramatic degeneration of the presynaptic calyx, supporting a neurodegenerative mechanism. Electron microscopy confirmed the loss of presynaptic terminals and healthy postsynaptic neurons. The protection from hearing loss by an nNOS antagonist suggests involvement of nitric oxide signalling in this presynaptic toxicity. We conclude that degeneration underlies the synaptic failure in the ...
AIMS: Bilirubin is associated with reduced risk of cardiovascular disease, as evidenced in conditions of mild hyperbilirubinaemia (Gilberts Syndrome). Little is known regarding myocardial stress resistance in hyperbilirubinaemic conditions or whether life-long exposure modifies cardiac function, which might contribute to protection from cardiovascular disease.. METHODS: Hyperbilirubinaemic rats and littermate controls underwent echocardiography at 3, 6 and 12 months of age, with hearts subsequently assessed for resistance to 30 min of ischaemia. Heart tissue was then collected for assessment of bilirubin content.. RESULTS: No difference in baseline cardiac function was evident until 6 months onwards, where Gunn rats demonstrated aortic dilatation and reduced peak ejection velocities. Additionally, duration of ventricular ejection increased progressively, indicating a negative inotropic effect of bilirubin in vivo. Ex vivo analysis of baseline function revealed reduced left ventricular pressure ...
What is jaundice in newborns? Jaundice is a yellow tint to a newborns skin and the white part of the eyes. It is a sign that theres too much bilirubin in the babys blood. The word for having too much bilirubin in the blood is hyperbilirubinemia (say hy-per-bil-ih-roo-bih-NEE-mee-uh). Jaundice usually appears in the...
Hyperbilirubinemia happens when there is too much bilirubin in your babys blood. Bilirubin is made by the breakdown of red blood cells. Its hard for babies to get rid of bilirubin. It can build up in their blood, tissues, and fluids.
Patient Presentation A 4-day-old male was transferred to a regional childrens hospital for direct hyperbilirubinemia. The infant was full term, was discharged at 2 days of life, and returned that morning to his private medical doctors office for routine followup. Mother reports that he had been breastfeeding sluggishly, was urinating well and had stools that…
الخلاصة. Background: Neonatal jaundice (NJ) is a significant disease among neonates in Najaf province. It manifests 19% of the total deliveries and 50% of the inpatients, and affects about 60% of term and 80% of preterm neonates during the first week of life. UGT1A1 is a cause of concern in NJ, because it is the most important underlying cause of unconjugated hyperbilirubinemia. Methods: A cohort of 85neonate sorted into three groups according to the TSB level. Group 1 ( ...
These pivotal data from STARTVerso™ are important for Boehringer Ingelheims HCV portfolio as they support the filing of a New Drug Application for faldaprevir with the Food and Drug Administration," said Peter Piliero, M.D., vice president, Clinical Development and Medical Affairs, Boehringer Ingelheim Pharmaceuticals, Inc. "These results take us a step closer towards our goal of making faldaprevir available for patients who urgently need HCV treatment." In the STARTVerso™ clinical trial program, adverse events (AEs) most commonly included nausea, fatigue, diarrhea, headache, anemia, weakness, rash and jaundice due to transient bilirubin elevation (unconjugated hyperbilirubinemia). In STARTVerso™1&2, anemia occurred in 14%, 13%, and 14% of patients taking 120mg and 240mg faldaprevir regimens or PegIFN/RBV alone, respectively. Hyperbilirubinemia occurred in 12% (120mg), 46% (240mg) and less than 1% (PegIFN/RBV) of patients, and was transient. ALT elevations in the faldaprevir arms were ...

The cause of post-transplant CNI-NCs is multifactorial and not ascribed solely to CNI toxicity. A total of 90 children (aged ,20 years) who underwent LDLT were evaluated to investigate the predictive factors associated with CNI-NCs. Twelve patients (13.3%) developed CNI-NCs after LDLT (age range, 2-15 years). The symptoms of CNI-NCs were seizures, VD, and stupor. The median onset of CNI-NCs was 10 days (range, 5-30 days) post-transplant. In the univariate analysis, higher recipient age at LDLT, donor age and recipients BW, lower actual GV/SLV and TAC dosage/BW, and higher mean T-Bil and sodium level for 7 days after transplantation were independently significantly associated with TAC-NCs ...

This Phase I trial determined the maximum tolerated dose of S-1 to be 50 mg/m2/day when administered to advanced cancer patients once daily for 21 days, followed by a 1-week break. DLTs included fatigue, nausea, vomiting, ileus, diarrhea, and hyperbilirubinemia. Myelosuppression was not a significant toxicity in our study, although it has been predominant in several previous studies (20 , 21) . Pharmacokinetic analysis revealed rapid oral absorption of S-1 components. The 5-FU AUC derived from S-1 observed at both dose levels (50 and 60 mg/m2 of tegafur) is ,10 times higher than we reported previously with administration of a single UFT dose of 100 mg/m2 (1225 and 1887 h·ng/ml versus 103 h·ng/ml; Ref. 25 ). Our 5-FU half-life of 2.6 h compares favorably with that of 5-FU bolus administration (8-14 min) and approximates that seen with UFT (7 , 26) .. Toxicity in our study did not differ significantly from that seen in two other Phase I studies that evaluated S-1 on a twice-daily schedule for 28 ...

TY - JOUR. T1 - Sixth hour transcutaneous bilirubin predicting significant hyperbilirubinemia in ABO incompatible neonates. AU - Bhat, Ramesh Y.. AU - Kumar, Pavan C.G.. PY - 2014/1/1. Y1 - 2014/1/1. N2 - Background: Neonates with ABO hemolytic disease are at greater risk for developing significant hyperbilirubinemia. We aimed to determine whether sixth hour transcutaneous bilirubin (TcB) could predict such a risk. Methods: TcB measurements were obtained at the 6th hour of life in blood group A or B neonates born to blood group O, rhesus factor compatible mothers. Subsequent hyperbilirubinemia was monitored and considered significant if a neonate required phototherapy/exchange transfusion. The predictive role of sixth hour TcB was estimated. Results: Of 144 ABO incompatible neonates, 41(OA, 24; O-B, 17) had significant hyperbilirubinemia. Mean sixth hour TcB was significantly higher among neonates who developed significant hyperbilirubinemia than those who did not (5.83±1.35 mg/dL vs. ...
OBJECTIVE: The recognition, follow-up, and early treatment of neonatal jaundice has become more difficult, since the earlier discharge of newborns from hospitals has become common practice. This prospective study was undertaken to identify the newborns at risk for developing significant hyperbilirubinemia later during the first days of life by measuring the serum bilirubin levels of the first 5 days of life to determine the critical predictive serum bilirubin value on the first day of life.. METHODOLOGY: A total of 498 healthy term newborns were followed with daily serum total bilirubin measurements for the first 5 days of life, and cases with serum bilirubin levels of ,/=17 mg/dL after 24 hours of life were defined to have significant hyperbilirubinemia.. RESULTS: No newborns had a serum total bilirubin level of ,/=17 mg/dL in the first 72 hours of life. Sixty of 498 cases (12.05%) had significant hyperbilirubinemia after 72 hours of life, and these cases had significantly higher bilirubin ...

Use of some protease inhibitors is associated with unconjugated hyperbilirubinemia as a result of inhibition of the UGT1A1 enzyme.. Elevated levels of unconjugated bilirubin are best characterized among individuals with Gilbert syndrome, which is the most common inherited cause of unconjugated hyperbilirubinemia, present in 3-10% of the general population. Gilbert syndrome arises through variants in the UGT1A1 enzyme, thus these PIs induce a biochemical picture similar to Gilbert syndrome. Although elevations of bilirubin may occasionally lead to scleral icterus or jaundice, cohort studies of individuals with Gilbert syndrome indicate bilirubin elevations may have antioxidant and anti-inflammatory properties and are associated with reduced risk of cardiovascular events.. Inflammation may also be relevant to cardiovascular (CV) risk, neurocognitive impairment and renal disease in HIV infection. This study seeks to investigate any association between antiretroviral associated HBR and CV risk ...

We demonstrated that tienilic acid, a diuretic drug withdrawn from the market because of hepatic failure, enhanced hyperbilirubinemia in Eisai hyperbilirubinuria rats (EHBR) with a defect of canalicular multidrug resistance-associated protein 2 (Mrp2). In contrast, no remarkable changes were noted in Sprague-Dawley (SD) rats, the parent strain for EHBR. To investigate a mechanism underlying this enhanced hyperbilirubinemia, we focused on comprehensive effects of tienilic acid on clinicopathological aspects and expression of hepatic transporters. Other than eventual hyperbilirubinemia with slightly increased biliary bilirubin, a single oral treatment of EHBR with tienilic acid at 300 mg/kg caused no changes in serum alanine aminotransferase and alkaline phosphatase, bile flow rate and biliary bile acid secretion, or hepatic morphology. In analyses of mRNA expression of the hepatic transporters, elevated Mrp3 expression in EHBR correlated with an increase in serum total bilirubin, suggesting increased

A report of a prediction rule for rebound hyperbilirubinemia (return of total serum bilirubin to phototherapy threshold within 72 hours of phototherapy termination) in newborns of at least 35 weeks gestation. Authors studied a group of ~7000 infants, 4.6% of whom had rebound hyperbilirubinemia. The formula is calculated as: 15 points if gestational age less than 38 weeks, minus 7 × (age in days at phototherapy initiation) minus 4 × (AAP phototherapy threshold − TSB at phototherapy termination) + 50. This score in turn can be applied to a curve (pictured) to predict rebound hyperbilirubinemia.. Chang 2016 (Pediatrics) , PubMed 12345678 , Author Search ...

Hemoglobin released from red blood cells is broken down into heme, and reduced to unconjugated (indirect) bilirubin which is then bound to serum albumin. Unconjugated bilirubin is converted to water-soluble conjugated (direct) bilirubin in the liver and stored in the gallbladder as bile. Bile is released into the intestines to assist in digestion and cholesterol metabolism as well as absorption of lipids and fat-soluble vitamins. Hyperbilirubinemia can be due to an increase in either unconjugated bilirubin or conjugated bilirubin levels. Conditions causing increased red blood cell destruction or decreased conjugation lead to unconjugated hyperbilirubinemia. Conditions that impair secretion of bile from liver or gallbladder result in conjugated hyperbilirubinemia. ...

Background: Although nondipper hypertension has been associated with increased cardiovascular morbidity and mortality, the relationship between bilirubin levels and nondipper hypertension remains unclear. Several studies have demonstrated that higher serum bilirubin levels inhibit inflammation and the proliferation of vascular smooth muscle cells, which may suggest a relationship between serum bilirubin levels and cardiovascular disease. The aim of this study was to compare serum bilirubin levels between dipper and nondipper hypertensive patients. Methods: The present study included 80 hypertensive patients who were stratified into two groups: 50 dipper patients (mean [± SD] age 51.5 ± 8 years; 29 male) and 30 nondipper patients (mean age 50.6 ± 5.4 years; 17 male). All patients underwent 24 h ambulatory blood pressure monitoring. Results: No statistically significant differences were found between the two groups in terms of basic characteristics. Total, direct and indirect serum bilirubin levels
Bilirubin is one of the most commonly used tests to assess liver function. Approximately 85% of the total bilirubin produced is derived from the heme moiety of hemoglobin, while the remaining 15% is produced from RBC precursors destroyed in the bone marrow and from the catabolism of other heme-containing proteins. After production in peripheral tissues, bilirubin is rapidly taken up by hepatocytes where it is conjugated with glucuronic acid to produce bilirubin mono- and diglucuronide, which are then excreted in the bile.. A number of inherited and acquired diseases affect one or more of the steps involved in the production, uptake, storage, metabolism, and excretion of bilirubin. Bilirubinemia is frequently a direct result of these disturbances.. The most commonly occurring form of unconjugated hyperbilirubinemia is that seen in newborns and referred to as physiological jaundice.. The increased production of bilirubin, that accompanies the premature breakdown of erythrocytes and ineffective ...
Fasting is associated with unconjugated hyperbilirubinemia in several species, including the horse. Studies in ponies showed that a 3-day fast decreased plasma clearance of bilirubin, cholic acid, and sulfobromophthalein (BSP). Since these organic anions are conjugated with different substrates, it is possible that observed differences in plasma clearance result from a general decrease in hepatic conjugating capacity during the animals fasting. To test this hypothesis, the effects of a 3-day Show moreFasting is associated with unconjugated hyperbilirubinemia in several species, including the horse.

Recordings were performed on the 3rd day of life and repeated 5-7 days post-appropriate therapy with photostimulation and exchange transfusion (when bilirubin concentration had decreased below 136 mM). Supplementary recordings were performed 3, 6 and 12 weeks later in order to assess test-retest reliability of components. Mean values of BAEP latencies were compared with those obtained in 40 age-matched control subjects using the ...
Bilirubin, resulting largely from the turnover of hemoglobin, is found in the plasma in two main forms: unconjugated or conjugated with glucuronic acid. Unconjugated bilirubin is transported into hepatocytes. There, it is glucuronidated by UGT1A1 and secreted into the bile canaliculi. We report a genome wide association scan in 4300 Sardinian individuals for total serum bilirubin levels. In addition to the two known loci previously involved in the regulation of bilirubin levels, UGT1A1 (P = 6.2 x 10-62) and G6PD (P = 2.5 x 10-8), we observed a strong association on chromosome 12 within the SLCO1B3 gene (P = 3.9 x 10-9). Our findings were replicated in an independent sample of 1860 Sardinians and in 832 subjects from the Old Order Amish (combined P , 5 x 10-14). We also show that SLC01B3 variants contribute to idiopathic mild unconjugated hyperbilirubinemia. Thus, SLC01B3 appears to be involved in the regulation of serum bilirubin levels in healthy individuals and in some bilirubin-related ...
Hyperbilirubinemia is felt to be a benign condition for infants born at term or near-term gestation. In ∼5% of healthy term infants, however, serum bilirubin values exceed 17 mg/dL (291 μmol/L), a value which the American Academy of Pediatrics deems significant.4 Levels exceeding 20 mg/dL (342 μmol/L) occur in 1.2% of healthy newborn infants.11 The vast majority of infants with serum bilirubin values in excess of 20 mg/dL remain well. They need minimal care other than the occasional use of phototherapy and careful monitoring of serum levels. Before 1990, kernicterus in the previously healthy-term infant was extraordinarily rare and for most pediatricians, it was a disease they were unlikely to see in their practice lifetimes. Since 1990, there has been an increase in the number of reported cases of kernicterus in the United States.7 Thirty-one cases have been reported in term infants who were well at the time of hospital discharge, and several additional cases have occurred in near-term ...
Introduction: In the neonatal period one of the frequently faced problems is jaundice .The American Academy of Paediatrics has published a set of practice parameters for the treatment of unconjugated hyperbilirubinemia in healthy term infants. We follow the guidelines published by the American Academy of Paediatrics. In current practice if the bilirubin reaches a level that would require phototherapy and if it is predicted to raise we will start phototherapy. A major role is being played by phototherapy in the treatment of hyperbilirubinemia. This management method may result in inherent complications. In this study level of serum sodium study is estimated in full term neonates those who are receiving phototherapy for jaundice. Aim and Objective: To determine the level serum sodium and to compare the levels before and after phototherapy in full-term hyperbilirubinemic neonates. Methods: We started the study after obtaining approval from Ethical Committee. From the neonates mother informed ...
In a large nationally representative cohort, we found an independent association between increasing concentration of serum total bilirubin and decreasing prevalence of PAD. We did not find evidence that this association is dependent on bilirubin levels beyond the reference range, on the presence of liver disease, or on alcohol intake. These data, together with evidence from experimental atherosclerosis, are consistent with the hypothesis that bilirubin is an endogenous protectant mechanism against PAD.. Inflammation and oxidative stress are essential to the pathogenesis of atherosclerosis.9-11 Bilirubin is a antioxidant under physiological conditions and suppresses inflammation in the vasculature.1,7 Additionally, bilirubin functions as a cytoprotectant.6 These properties appear to allow bilirubin to inhibit multiple steps in atherogenesis. Bilirubin inhibits inflammatory cytokine-induced endothelial cell expression of vascular cell adhesion molecule (VCAM)-1,7 an initial step in ...

N2 - Bilirubin is generated from the breakdown of heme by heme oxygenase and the reduction of biliverdin by the enzyme biliverdin reductase. Several large population studies have reported a significant inverse correlation between plasma bilirubin levels and the incidence of cardiovascular disease. Protection from cardiovascular disease is also observed in patients with Gilberts syndrome which is a disease characterized by mutations in hepatic UGT1A1, the enzyme responsible for the conjugation of bilirubin into the bile. Despite the strong correlation between plasma bilirubin levels and the protection from cardiovascular disease, the mechanism by which increases in plasma bilirubin acts to protect against cardiovascular disease is unknown. Since the chronic antihypertensive actions of bilirubin are likely due to its renal actions, ...
