The mother said that the patient eats well, has normal stool and urine color. Its her first child from first healthy pregnancy. The patient was born on time and delivered via spontaneous vaginal delivery with no complications. Family history is significant for a maternal aunt who died as an infant of unknown causes. The patient is afebrile and vital signs are within normal limits. On physical examination, he is awake, calm, and looks healthy, except for the yellow tone of the skin and scleral icterus. Laboratory findings are significant for elevated unconjugated bilirubin, with a normal complete blood count. Other routine laboratory blood tests are within normal limits. The patient is treated with phototherapy, but his jaundice worsens and his unconjugated hyperbilirubinemia persists well into the second week of life. Which of the following is the most likely diagnosis in this patient?? A: CriglerNajjar syndrome type II, B: CriglerNajjar syndrome type I, C: Hemolytic anemia, D: Gilbert syndrome, E: Neonatal jaundice,  <response>: This is a clinical case of neonatal jaundice in a 3-day-old infant. The key findings are:- Yellowing of skin and scleral icterus indicating jaundice- Elevated unconjugated bilirubin- Jaundice worsened despite phototherapy - Persistent unconjugated hyperbilirubinemia into second week of lifeBased on the persistent unconjugated hyperbilirubinemia not responsive to phototherapy, the most likely diagnosis is a congenital disorder of bilirubin metabolism rather than physiological neonatal jaundice. The two main options are Crigler-Najjar syndrome type I and II. Type I is more severe with complete absence of UGT1A1 enzyme activity. Type II has partial UGT1A1 deficiency. The lack of response to phototherapy makes Crigler-Najjar syndrome type I more likely than type II. Hemolytic anemia is unlikely given normal CBC. Gilbert syndrome and physiological neonatal jaundice are also unlikely given the severity and persistence of hyperbilirubinemia.B: CriglerNajjar syndrome type I
