Normalization of Serum Alkaline Phosphatase in Primary Sclerosing Cholangitis Associated with Ulcerative Colitis

摘要

Primary sclerosing cholangitis (PSC) is commonly associated with ulcerative colitis (UC). PSC progresses independently of UC ultimately resulting in liver failure. There is no established medical treatment to improve the natural course of PSC. Normalization of serum alkaline phosphatase (ALP) in early stage might delay the progress of PSC. A 20-year-old female, had a sudden attack of right hypochondralgia with high fever and abnormal liver function tests without elevation of bilirubin: ALP 478 IU/L, aspartate aminotransferase 360 IU/L, alanine aminotransferase 174 IU/L. Abnormal liver function tests returned to normal after the attacks. Morphological examinations initially indicated then confirmed a diagnosis of PSC. One month after displaying PSC symptoms administration of ursodeoxycholic acid was initiated. Similar attacks of cholangitis were repeated several times over the following two years. Even in the absence of these attacks, she always suffered postprandial hypochondralgia. There was no acute cholangitis in the year prior to the last hospitalization due to abdominal pain and bloody diarrhea. Findings were consistent with UC in the form of entire colitis. Sulfasalazine, metronidazole and semi-vegetarian diet (SVD) were initiated. Metronidazole is routinely used in inflammatory bowel disease (IBD) in our practice with the expectation of elimination of any potentially pathogenic bacteria. SVD was designed for IBD hoping to increase beneficial bacteria. A remission of UC was ascertained during hospitalization. Elevated ALP, in the absence of clinical cholangitis, was decreased to normal after the therapy for UC.
