| Popis: | Hemolitička bolest fetusa i novorođenčeta (HBFN) je posljedica majčine aloimunizacije na eritrocitne antigene fetusa. Aloimunizacija na D antigen iz Rhesus (Rh) sustava krvnih grupa ima posebno značenje budući da se radi o najjačem eritrocitnom imunogenu. Otkako se unatrag četiri desetljeća rutinski provodi postnatalna profilaksa imunizacije davanjem anti-RhD imunoglobulina RhD negativnim ženama, drastično je smanjen mortalitet zbog HBFN. Uvođenjem antenatalne profilakse klinički značajna HBFN je postala izuzetno rijetka. Sporadični teški oblici bolesti su uglavnom posljedica nedosljednosti u provođenju profilakse. U slučaju koji opisujemo nije prepoznat rizik imunizacije tijekom prve majčine trudnoće, te je izostala antenatalna prevencija. Nakon primarne imunizacije, u drugoj je trudnoći s RhD pozitivnim djetetom došlo do žestokog sekundarnog imunološkog odgovora majke i ranog razvoja teške fetalne anemije. Intrauterine transfuzije su spasile vitalno ugroženi fetus, ali su istodobno uzrokovale snažnu eritroidnu supresiju. Anemija koja je trajala mjesecima nakon rođenja liječena je ponavljanim transfuzijama, te humanim rekombinantnim eritropoetinom. Unatoč teškoj kliničkoj slici, kratkoročni ishod bolesti je povoljan i dječak zasada ima uredan rast i razvoj. Ipak, rizici kasnih posljedica, a posebice neurorazvojnih odstupanja nalažu daljnje pomno praćenje djeteta. Opisani slučaj ukazuje na trajnu aktualnost problematike Rh imunizacije u nas. Provođenje antenatalne imunoprofilakse je prvi i ključni korak u kvalitetnoj prevenciji HBFN. Hemolytic disease of the fetus and newborn (HDFN) is a consequence of maternal alloimmunization against fetal red blood cell antigens. Alloimmunization against D antigen from Rhesus (Rh) blood group system is particularly important because of its strong immunogenicity. During the last few decades, the introduction of RhD prophylaxis by postpartum administration of anti-D immunoglobulin to RhD negative women, now improved with antenatal prophylaxis, has led to a dramatic decrease in perinatal mortality and morbidity from HDFN. However, severe cases have not disappeared, mostly due to prophylaxis failure. In our case, inappropriate prenatal care during the first pregnancy in an RhD negative mother resulted in primary immunization. In the next pregnancy with an RhD positive child, the mother’s secondary immune response was extremely strong and led to early development of severe fetal anemia. The fetus survived thanks to the treatment with intrauterine transfusions (IUT), but they caused suppression of erythropoiesis, which lasted for months after birth. The long lasting, late anemia was treated with repeated postnatal red cell transfusions and recombinant human erythropoietin (rHuEPO). Despite the severity of HDFN in our case, the short-term outcome is good. The boy has normal growth until now, but due to the possibility of an adverse long-term neurodevelopmental outcome, this case requires continuous follow up. It also reminds of the fact that RhD alloimmunization remains an actual problem in daily routine. Antenatal prophylaxis is a crucial step in quality care of those who are at a risk of HDFN. |
