Brief Summary:
PSC is a chronic cholestatic disorder. The investigators intend to study some telomere parameters and telomere length in order to predict a premalignant state.

Condition or disease
Primary Sclerosing Cholangitis Inflammatory Bowel Disease

Detailed Description:
Primary sclerosing cholangitis (PSC) and colitis are chronic inflammatory disorders with malignant potential. Telomerase is an enzyme complex that lengthens telomeres and has enhanced expression in numerous malignancies. In this study, we evaluated the telomerase gene copy number, telomere length, cells in senescence, aneuploidy and additional parameters of telomere dysfunction from peripheral blood lymphocytes of patients.
