Scientific title | Reducing bilirubin-induced neurological dysfunction in preterm infants: additional use of the Bilirubin:Albumin Ratio in the treatment of hyperbilirubinemia |
Study acronym | BARTrial |
Study objectives | Neonatal jaundice due to unconjugated hyperbilirubinemia occurs in almost all preterm infants and is potentially neurotoxic. The current treatment modalities (phototherapy and exchange transfusion) are based on Total Serum Bilirubin (TSB) levels, but are not evidence based. TSB is an unreliable predictor of Bilirubin Induced Neurological Dysfunction (BIND). Because low albumin levels appear to potentiate BIND, the Bilirubin:Albumin (B:A) ratio is an interesting additional factor to assess in the management of preterm infants with hyperbilirubinemia. |
Ethics approval(s) | The Medical Ethics Review Committee (METC) of the University Medical Center Groningen (UMCG) reviewed and approved the study protocol on the 9th January 2007 (ref: ABR nr: NL 14811.042.06). |
Health condition(s) or problem(s) studied | Hyperbilirubinemia, bilirubin induced neurological dysfunction |
Intervention | Study group: Hyperbilirubinemia is evaluated daily, in the first ten days of life using the B:A ratio together with TSB. Treatment guidelines (phototherapy and exchange transfusion limits) are based on B:A ratio and TSB (whichever comes first) Control group: Hyperbilirubinemia is evaluated daily, in the first ten days of life using TSB only (care as usual) versus only TSB. Treatment guidelines (phototherapy and exchange transfusion limits) are based on TSB only. |

Primary outcome measure | Blinded assessment of the participants outcome is performed. Primary outcome: 1. Neurodevelopmental outcome at the age of 18 to 24 months using standardised neurological examination will be measured from October 2008 till April 2010 2. Mental- and Psychomotor Developmental Index scores (MDI and PDI: Dutch version of Bayley scales of infant development II) will be measured from October 2008 till April 2010 |
Secondary outcome measures | Secondary outcomes: 1. Peak total serum bilirubin will be measured from April 2007 till January 2008 2. Duration of hyperbilirubinaemia will be measured from April 2007 till January 2008 3. Duration of phototherapy will be measured from April 2007 till January 2008 4. Number of exchange transfusions will be measured from April 2007 till January 2008 Other outcomes are complications of prematurity such as: 1. Mortality will be measured from April 2007 till the end of this study (April 2010) 2. Bronchopulmonary Dysplasia (BPD) will be measured from April 2007 till January 2008 3. Patent Ductus Arteriosus (PDA) will be measured from April 2007 till January 2008 4. Retinopathy of Prematurity (ROP) will be measured from April 2007 till January 2008 5. Necrotising Enterocolitis (NEC) will be measured from April 2007 till January 2008 6. Intraventricular Haemorrhage (IVH) etc., will be measured from April 2007 till January 2008 Other potential outcomes to be evaluated in parts of the study population are: 1. Maturation pattern of serial Auditory Brainstem Responses (ABR) in a part of the study populations that is treated in those Neonatal Intensive Care Units (NICUs) that are able to perform serial ABRs. This will be measured from April 2007 till January 2008 2. Free (unbound) unconjugated bilirubin will be measured in from January 2008 till October 2008 3. Lumirubin will be measured from April 2007 till January 2008 4. CFM (Cerebral Function Monitor) will be measured from April 2007 till January 2008 5. Movement score will be measured from April 2007 till January 2008 6. Transcutane bilirubin measurement will be measured from April 2007 till January 2008 |
