Active clinical trials for "Jaundice"

Data accumulated from medical record collected from January 2008 until December 2018

Due to actual standard of neonatal care bilirubin is monitored in neonates several times after birth to avoid hyperbilirubinemia. As the peak is often one or two days after discharge from hospital a more precise predication than the actual one is desirable to avoid needlessly follow-ups. The precision of an algorithm to predict bilirubin values 24-48h into the future is evaluated in this study.

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.

This is an observational prospective study. The main purpose is to evaluate the stability of the Bilistick system in a humid and hot climate compared to the quantitative test for serum bilirubin (SBR) measurement currently used, the BR-501 total bilirubin meter, kept in a controlled environment. The secondary aim is to assess the operational feasibility of the Bilistick system in a tropical limited-resource setting, when used by locally trained nurses.

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 main objective of the study is to evaluate the size of the common bile duct (CBD) in a large cohort of patients with jaundice secondary to pancreatic head or distal bile duct malignancy undergoing diagnostic EUS for tissue acquisition or evaluation of resectability and to establish factors associated with a dilation of the CBD greater than 15mm.

To assess the size of the common bile duct in a large cohort of patients with jaundice following a malignant tumor of the head of the pancreas or the distal bile duct receiving a diagnostic EA for biopsy and / or for evaluation of tissue resectability.

Patients with obstructive jaundice (OJ) often require surgical, endoscopic or radiological interventions to facilitate biliary drainage and relieve jaundice. However it is known that patients with OJ have increased surgical risks than non-jaundiced patients undergoing the same procedures. Surgery for severe OJ is associated with a significant post-operative mortality (10-15%) and morbidity (30-65%). The commonest complications are related to sepsis but the pathophysiological mechanisms behind this susceptibility to bacterial infection are not clear. Recent work has shown a pivotal role of bile in the maintenance of enterocyte tight junctions and the expression of tight junction-associated proteins which could account for the translocation of enteric bacteria and bacterial products to mesenteric lymph node complexes, the portal circulation and subsequently the liver. Some of these bacterial products, such as endotoxin and quorum sensing signalling molecules (QSSMs), have immunomodulatory properties which may dampen normal immune responses to infection resulting in life-threatening organ dysfunction. Bacterial endotoxin and quorum sensing signalling molecules (QSSMs) represent good candidates for the mediators of this immune suppression and although there is a compelling case for their involvement in the pathogenesis of sepsis, evidence to support their involvement in the aetiology of infection in OJ is currently lacking.

Specific Aim 1: To determine total serum bilirubin (TSB) and unbound bilirubin (Bf) levels in term and late preterm infants during the first week of life. Specific Aim 2: Measure Bf levels in breast fed and formula fed infants and examine their relationship to unbound fatty acid (FFAu) levels. Specific Aim 3: To demonstrate that phototherapy results in different changes in TSB and Bf.

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.
