Abstract

Objective: While routine administration of rhesus (Rh) immunoglobulin has significantly reduced the incidence of Rh alloimmunization, maternal alloimmunization to other red cell antigens remains a contributor to perinatal morbidity and mortality. Although the Kell antigen is seen on the red cells of only 9% of the general population, attention to Kell antibodies continues to increase. Case Report: A case of fetal hydrops was sonographically detected at 30 weeks of gestation. Antenatal tests to evaluate the fetus’s condition clearly showed that the level of hemolytic disease was critical and the baby was delivered prematurely due to fetal distress. The combination of anemia, reticulocytopenia, hydrops fetalis, and a positive indirect Coombs test suggested Kell isoimmunization. The baby was successfully treated with exchange transfusion of Kell- negative packed red cells, and was discharged on postnatal d 30. Conclusion: The presented case of hydrops fetalis was due Kell alloimmunization that was detected during the postnatal period, and thus we plan to discuss the perinatal approach to Kell immunization.

Özet

Amaç: Günümüzde Rhesus (Rh) immunoglobulinin yaygın olarak uygulanması RhD alloimmünizasyon insidansında azalmaya neden olurken RhD dışındaki eritrosit antijenleri ile maternal alloimmunizasyon perinatal morbidite ve mortaliteye yol açmaya devam etmektedir. Kell antijeni toplumda yalnızca %9 oranında bulunmasına rağmen bu antijene bağlı alloimmunizasyon günümüzde ön plana çıkmaya başlamıştır. Olgu Sunumu: Hastamız 30. gebelik haftasında antenatal fetal hidrops tanısı almıştı. Fetal durumu değerlendirmeye yönelik antenatal testler kritik düzeyde hemolitik hastalığı gösterdi, ancak hasta fetal distres nedeniyle prematüre olarak doğurtuldu. Anemi, retikülositopeni, hidrops fetalis ve pozitif indirekt Coombs testi Kell izoimmunizasyonunu düşündürdü. Postnatal dönemde Kell-negatif eritrosit süspansiyonu ile kan değişimi uygulanan hasta postnatal 30.gün şifa ile taburcu edildi. Sonuç: Bu makalede, Kell izoimmunizasyonuna bağlı geliştiğini postnatal dönemde saptadığımız bir hidrops fetalis olgusu sunularak Kell immunizasyonuna perinatal yaklaşımın tartışılması planlandı. Bu durum fetusun antijen negatif uygun kan ile başarılı bir şekilde tedavi edilmesine olanak sağlayacaktır.
