Abstract
Objective: Hyperbilirubinemia is one of the most serious problems encountered in the newborn period. There are many reasons for newborn jaundice etiology. In this study, we aimed to investigate the frequency of subgroup incompatibilities in the etiology of hyperbilirubinemia, its association with blood group incompatibilities and the treatments given.
Material and Methods: In this retrospective study, we evaluated 240 newborn patients who were diagnosed as hyperbilirubinemia in Dicle University Faculty of Medicine Neonatal Unit between January 2016 and June 2017.
Results: Subgroup incompatibility was detected in 32% of cases. Only 35.4% of cases with subgroup incompatibility were found just subgroup incompatible. Subgroup C incompatibility was found in 43%, Rh incompatibility in 35% and subgroup E incompatibility in 33% of cases. Direct Coombs Test positivity was detected in 38% of cases.
Blood exchange procedure was performed in 16.5% of cases with subgroup incompatibility. Blood exchange was applied to 40.9% of those with Rh and C incompatibility. Only 50% of those with Rh and C subgroup incompatibility were applied blood exchange (this group was not accompanied by Rh or ABO incompatibility).
Intravenous immunoglobulin treatment was given in 24.1% of cases with subgroup incompatibility in total. Intravenous immunoglobulin treatment was given also to 17.85% of cases with only subgroup incompatibility that did not accompany Rh and ABO incompatibility.
Conclusion: Detection of subgroup blood incompatibilities in cases with neonatal jaundice is important in diagnosis, treatment and follow-up.
