Active clinical trials for "Hyperbilirubinemia"

The purpose of this study is to compare the demographic, metabolic, and genomic characteristics of patients who develop severe hyperbilirubinemia to patients who never developed a significant bilirubin level.

Neonatal hyperbilirubinaemia (NH) is common among healthy neonates and normally resolves within a week. Untreated pathological hyperbilirubinaemia, however, can result in long-term neurological sequelae, which compromise childhood development, or may result in perinatal death. True population-based data from middle to low-income countries are scarce and NH contribution to morbidity and mortality remains unclear. With this study the investigators aim at assessing the prevalence of neonatal hyperbilirubinaemia in a cohort of newborns in a maternity hospital in Kinshasa, the Democratic Republic of Congo, and at evaluating the possible risk factors for NH in the mother and the baby.

Prospective comparison of measurement of bilirubin in jaundiced newborns by a transcutaneous device (bilirubinometer) and laboratory analysis of blood samples. We hypothesise that correlation of the two measurements depend on bilirubin level, gestational age as well as postnatal age.

The prevalence of mild hyperbilirubinemia, also known as Gilbert´s Syndrome, is usually defined using an unconjugated bilirubin (UCB) blood concentration above 17.1 µmol/l. The prevalence of GS is remarkably common, affecting 5-10% (depending on ethnicity and gender) of the adult population. The aim of this project is to investigate whether there is a difference in health related marker between 60 subjects with Gilbert´s Syndrome (mild hyperbilirubinaemia) and 60 age and gender matched control subjects.

The values of laboratory examinations which are useful for the diagnoses of appendicitis are white blood cell count (WBC), C-reactive protein (CRP) and erythrocyte blood sedimentation rate (ESR). However up to date there is no laboratory marker for the pre-operative diagnosis of appendiceal perforation in acute appendicitis. Recently hyperbilirubinaemia has been associated with appendiceal perforation. Aim of this retrospective study is therefore to investigate if hyperbilirubinaemia has a diagnostic value for the pre-operative diagnosis of appendiceal perforation in patients with appendicitis.

The study was designed to assess whether chest shielding during phototherapy reduces the incidence of PDA, as assessed by serial echocardiographic examinations, in a population of extremely preterm infants born at lower 30 week gestation.

A team of researchers at Rice University in partnership with clinicians at Queen Elizabeth Central Hospital created BiliSpec, a low-cost battery-powered reader designed to immediately quantify serum bilirubin levels from a small drop of whole blood applied to a lateral flow strip. The simple and affordable BiliSpec system offers a faster and more cost-effective means to detect neonatal jaundice in under-resourced clinics and determine when phototherapy is needed. The goal of this study is to validate the accuracy of the BiliSpec device in measuring bilirubin levels in neonates relative to the laboratory spectrophotometric bilirubinometer and transcutaneous bilirubinometer measurements.

The purpose of this protocol is to make Stanate (TM) [stannsoporfin, tin-mesoporphyrin] available to infants who meet the following criteria: the infant has a very high level of bilirubin without an adequate clinical response to phototherapy; the infant requires an exchange transfusion; and the family refuses to allow the administration of blood products, particularly on religious grounds, such as within the Jehovah's Witness community.

The purpose of this study is to detect differences in the enzymatic activity of matrix metalloproteinases in patients with malignant obstructive hyperbilirubinemia before and after percutaneous biliary drainage.

This study aims to evaluate the incidence and risk factors of hyperbilirubinemia following major cardiac or thoracic aorta surgery, and to determine the clinical impacts of the hyperbilirubinemia on postoperative mortality and morbidity.
