The initial approach involved rapid evaluation, phototherapy, and dose monitoring of serum bilirubin levels. Follow-up induded maintenance on folic acid, monitoring blood counts, and educating the parents about the course of pyruvate kinase deficiency, especially aplastic crisis. We suggest that the informed family practitioner can manage neonatal hyperbilirubinemia and pyruvate kinase deficiency with referrals at critical times to pediatric or surgical specialists. The practitioner must be able to recognize quickly the need for exchange transfusion for severe jaundice and for blood transfusions or splenectomy when significant anemia or aplastic crisis occurs.
