Schizophrenia-Associated Idiopathic Unconjugated Hyperbilirubinemia (Gilbert's Syndrome): 3 Case Reports

Letter to the Editor

Sir: Idiopathic unconjugated hyperbilirubinemia (Gilbert’s
syndrome) is a relatively common congenital hyperbilirubinemia
occurring in 3% to 7% of the population. Recently, it
was reported that schizophrenic patients showed a significantly
higher frequency of hyperbilirubinemia relative to patients with
other psychiatric disorders and the general healthy population.
However, there has been only one previous case report of
Gilbert’s syndrome occurring in a schizophrenic patient.
