00:00 Let's move on to a next case, A 30-year-old man with no past medical history is seen in clinic for intermittent yellowing of his eyes. 00:09 He currently feels well with no complaints. 00:12 Two weeks ago, he noticed his eyes turn yellow for a few days. 00:16 He had a seasonal cold virus at that time. 00:19 It resolved without any intervention. 00:22 Vitals are normal, physical exam is unremarkable and there is no hepatosplenomegaly. 00:27 His labs show a total bilirubin of 2.5 (mg/dL) with direct bilirubin 0.4 (mg/dL). 00:34 His CBC, AST, ALT, alkaline phosphatase, and GGT and Albumin are all normal, and the peripheral smear is also normal. 00:43 So what is the most likely diagnosis? So, let's review. 00:49 He is a young, healthy male, with intermittent jaundice that occurs during periods of stress as noted when he had this occurred during a cold virus. 00:59 He has a mild isolated, unconjugated hyperbilirubinemia. 01:05 But the rest of his lab studies are fairly normal. 01:08 So, that brings us back to our diagnostic algorithm for hyperbilirubinemia. 01:13 We can hone in on the fact as mostly unconjugated or indirect hyperbilirubinemia and it's an isolated bilirubin elevation. 01:23 So that brings to either hemolysis, Gilbert Syndrome or Crigler-Najjar Syndrome. 01:28 We return to our case at this point. 01:31 We also noticed here that he has a normal peripheral smear. 01:36 This indicates that he has no ongoing hemolysis. 01:39 So now, we know our most likely diagnosis is Gilbert Syndrome. 01:44 You might have noticed that Crigler-Najjar is also on the differential here but it is a congenital condition, so usually it would present earlier in life and would not present at the age of 30. 01:57 Thank you very much for your attention.
