Clinical course of primary sclerosing cholangitis and concomitant ulcerative colitis - a preliminary report of retrospective study among patients from Southern Poland.

UNLABELLED: Both ulcerative colitis (UC) and primary sclerosing cholangitis (PSC) are chronic and progressive diseases of uncertain etiology, that may affect one patient. Approximately 70% of PSC cases are also diagnosed with UC, whereas in the group of UC the prevalence of PSC is about 2-5%. The aim of the study was to compare clinical courses of PSC and UC in patients diagnosed with both diseases to those with the confirmed diagnosis of either PSC or UC. Three groups were distinguished and evaluated: patients with PSC and UC (n = 17) and two control groups: patients with PSC (n = 4) and with UC (n = 13). Clinical data, symptoms, laboratory tests, results of the magnetic resonance cholangiopancreatography and colonoscopy were analyzed to compare clinical courses of these diseases between the groups.
CONCLUSION: there is no correlation between clinical course of simultaneous PSC and UC. However, it may differ depending on co-occurrence of the other disease.
