Diagnostic value of soluble programmed cell death protein-1 in type-1 autoimmune hepatitis in Egyptian children.

Programmed cell death protein-1 (PDCD1) is considered a key factor in immune regulation and is expressed mainly on activated T cells. The current study aimed to assess the clinical value of soluble PDCD1/PD1 as a marker for diagnosing type-1 autoimmune hepatitis in children. Sixty children with chronic hepatitis as patients' groups further divided into autoimmune hepatitis group and other chronic liver disease group and 20 healthy children as a control group were enrolled in this study.
