, this prospective study on neonatal jaundice was carried out in Qatif Central Hospital. A total of 132 neonates with jaundice (26 per year) were admitted into the pediatric medical ward. Glucose-6-phosphate dehydrogenase deficiency (34.9%) and ABO incompatibility (24.2%) were the main associated factors. Septicemia and exposure to icterogenic agents were not common. In 40.2%, there were no associated factors. Of the 132 mothers, 93.9% were breast-feeding. Mean peak bilirubin levels and lowest hemoglobin values were similar in all the groups. There was no case with kernicterus or death. We concluded that since glucose-6-phosphate dehydrogenase deficiency was the most common factor associated with neonatal jaundice, further evaluation of the role of icterogenic agents in the etiology of jaundice in glucose-6-phosphate dehydrogenase-deficient neonates is needed. Meanwhile, parents must be educated on the dangers of exposing their babies to fava beans, naphthalene and other icterogenic agents.Neonatal jaundice (NNJ) is a worldwide problem, occurring in all races. In the USA, it occurs in 60% to 80% of neonates in the first week of life.1 Causes of NNJ vary in different parts of the world. In term infants, glucose-6-phosphate dehydrogenase (G-6-PD) deficiency was reported as a common cause of severe NNJ and kernicterus in Nigeria, 2,3 Sardinia, 4 and Southeast Asia. 5,6 In Saudi Arabia, hemoglobinopathies and G-6-PD deficiency are common. 7,8 In some parts of the world where G-6-PD deficiency is commonly associated with NNJ, environmental factors may play an important role in the pathogenesis of severe neonatal hyperbilirubinemia.4 -6 -910 Neonatal jaundice will continue to be an important research subject because of the potential risk of damage to the neonatal brain (kernicterus) in association with severe unconjugated hyperbilirubinemia. [11][12][13] It is important, therefore, to continue to document the etiology and magnitude of the problem of severe NNJ in different parts of the world, as this may help to identify ways of preventing it.In this prospective study, the associated etiological and environmental factors of jaundice in all neonates admitted to Qatif Central Hospital (QCH) from outside with jaundice were evaluated. To the best of our knowledge, this is the first report on NNJ from Saudi Arabia.
Patients and SubjectsThe study was conducted prospectively between January 1989 and December 1993. All neonates admitted from outside into QCH with jaundice during this period were studied. For each patient, place of antenatal care (ANC) and delivery, gestational age (GA), birth weight (BW), sex, duration of jaundice, weight, other associated symptoms (like poor feeding, fever), condition of the umbilical slough, rectal temperature, method of feeding and the status of primitive reflexes were recorded.On admission, routine serum bilirubin (SBR), complete blood count (CBC), blood group (baby and mother) Coombs' test and G-6-PD screening test were done. In neonates with suspected sepsis, either from the condition o...
