1/62. Overlapping syndrome of autoimmune hepatitis and primary sclerosing cholangitis associated with pyoderma gangrenosum and ulcerative colitis.We describe the case of a 18-year-old male patient who first presented with decompensated cirrhosis, fever and generalized lymphadenopathy. He had abnormal results for liver biochemical tests, with a hepatitic-like picture and high titre of antinuclear antibodies. According to the scoring system proposed by the International Autoimmune hepatitis Group he had 'definite' autoimmune hepatitis and responded well to immunosuppressive treatment. One year later he developed pyoderma gangrenosum which was successfully treated with cyclosporine. Two years later he experienced bloody diarrhoea as a first presentation of ulcerative colitis. At that time both the cholestatic biochemical picture and the cholangiographic appearances of the biliary tree were consistent with primary sclerosing cholangitis. Despite the addition of azathioprine and ursodeoxycholic acid to his treatment regime he developed recurrent episodes of cholangitis and intractable pruritus for which he underwent successful liver transplantation.- - - - - - - - - - ranking = 1keywords = colitis (Clic here for more details about this article) |
2/62. Symptomatic chronic calcific pancreatitis in a patient with idiopathic ulcerative colitis and sclerosing cholangitis.Although sclerosing cholangitis is well recognized to occur in patients with idiopathic inflammatory bowel disease, pancreatitis as a complication of ulcerative colitis is uncommon. We describe a patient who had idiopathic ulcerative colitis, primary sclerosing cholangitis and calcific pancreatitis with endocrine pancreatic deficiency, a rare combination.- - - - - - - - - - ranking = 1.2keywords = colitis (Clic here for more details about this article) |
3/62. Immunological similarities between primary sclerosing cholangitis and chronic sclerosing sialadenitis: report of the overlapping of these two autoimmune diseases.Primary sclerosing cholangitis (PSC) is characterized by destructive inflammation and fibrosis affecting the bile ducts. The etiology of PSC is still unknown, although lymphocytic infiltration in the portal areas suggests an immune-mediated destruction of the bile ducts. patients with one autoimmune disease often suffer from one or more other autoimmune diseases. It is well known that there is a close relationship between PSC and inflammatory bowel disease, particularly ulcerative colitis(UC). However, the pathological findings in UC and other overlap diseases do not resemble those of PSC. In the present study, we report a patient with chronic sclerosing sialadenitis (Kuttner's tumor) and PSC. It is compared the sclerosing changes in both salivary glands and bile ducts histologically. In addition, the expression pattern of mast cell tryptase, b-FGF, and HLA-DR were examined in both tissues immunohistochemically. Histological features of sclerosing change in both salivary and bile ducts were quite similar. Marked mast cell infiltration and b-FGF expression were seen in the sclerosing areas in both tissues. In active inflammatory areas of the salivary glands, HLA-DR expression was also seen. We hypothesized that similar immune reactions occur in both the salivary gland and bile ducts and are responsible for the fibrosis that follows.- - - - - - - - - - ranking = 0.2keywords = colitis (Clic here for more details about this article) |
4/62. Overlap syndrome between autoimmune hepatitis and primary sclerosing cholangitis in two cases.The overlap syndrome between autoimmune hepatitis and primary sclerosing cholangitis is a rare condition and only few cases have been published, partly associated with ulcerative colitis, but not with Crohn's disease. We report an autoimmune hepatitis/primary sclerosing cholangitis overlap syndrome in a female patient with Crohn's disease. In addition, a second case of overlap syndrome is reported in a man without inflammatory bowel disease. A 24-year-old woman was referred with a 10-month history of diarrhoea and biochemical changes including elevated serum levels of alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase and immunoglobulin g. Enzyme linked immunosorbent assay showed that antinuclear autoantibodies were elevated. Immunofluorescence for perinuclear-staining antineutrophil cytoplasmatic antibodies was positive. Diagnostic criteria of definite autoimmune hepatitis according to the International Autoimmune hepatitis Group were fulfilled. Liver biopsy simultaneously showed criteria of autoimmune hepatitis and primary sclerosing cholangitis. Endoscopic retrograde cholangiography demonstrated features of primary sclerosing cholangitis. colonoscopy and colonoscopic biopsies indicated an active Crohn's disease affecting the terminal ileum and the ascending and transverse colon. Furthermore, we report the case of a 28-year-old man with known primary sclerosing cholangitis for the previous 6 years, and who developed jaundice and a marked increase of aspartate aminotransferase, alanine aminotransferase and immunoglobulin g, leading to the diagnosis of definite autoimmune hepatitis. A review of the literature revealed only 16 cases of an autoimmune hepatitis/primary sclerosing cholangitis syndrome in patients without inflammatory bowel disease or in association with ulcerative colitis. We report two additional cases, one case showing an association with Crohn's disease.- - - - - - - - - - ranking = 0.4keywords = colitis (Clic here for more details about this article) |
5/62. Sequential occurrence of primary sclerosing cholangitis and autoimmune hepatitis type III in a patient with ulcerative colitis: a follow up study over 14 years.In 1983, a female patient born in 1963 presented with symptoms of ulcerative colitis and typical clinical and histological signs of primary sclerosing cholangitis (PSC). At this time only pANCA were positive while other marker antibodies for autoimmune liver disorders could not be detected. In summer 1987 the clinical picture changed and was replaced by laboratory and histological signs typical of autoimmune hepatitis (AIH). Thus, IgG levels increased considerably and cholestatic enzymes became normal. For the first time, anti-liver-pancreas antibodies (LP), a diagnostic marker for AIH type III could be detected. In the following years several relapses occurred also induced by repeated discontinuation of immunosuppressive therapy. Symptoms of colitis persisted but signs of cholestasis remained absent for the following ten years. In 1997, colitis exacerbated again and colectomy had to be performed together with liver transplantation. Surprisingly, histology of the explanted liver now showed the typical features of PSC stage III/IV while the significant criteria for AIH were now lacking. Thus, progression to cirrhosis was, probably, mainly induced by the biliary destructive and fibrotic process although biochemical and serological data were clearly indicative of an autoimmune, i.e. AIH-related manifestation.- - - - - - - - - - ranking = 1.4keywords = colitis (Clic here for more details about this article) |
6/62. Paradoxical progression of biliary strictures against recovery of biochemical parameters under ursodeoxycholic acid treatment in a case of primary sclerosing cholangitis with ulcerative colitis.ursodeoxycholic acid (UDCA) treatment for primary sclerosing cholangitis (PSC) has been considered a rational therapy, though its effectiveness in the clinical course is still open to discussion. In this report, we describe a 22-year-old man with PSC at an early stage, which was associated with ulcerative colitis (UC). He showed progressive strictures of bile ducts over a 1.5-year period in spite of an improvement in the biochemical parameters by UDCA treatment. Therefore, care should be taken in interpreting the effectiveness of UDCA, because the biochemical parameters may not change in parallel with the clinical course of PSC.- - - - - - - - - - ranking = 1keywords = colitis (Clic here for more details about this article) |
7/62. pyoderma gangrenosum associated with sclerosing cholangitis, type 1 diabetes mellitus and ulcerative colitis.We describe the case of a 22-year-old black female with type 1 diabetes mellitus diagnosed when she was 12 years old. She first presented (March 1994) with pustules and ulcerations on the upper and lower limbs, trunk and scalp at the age 17. The diagnosis of pyoderma gangrenosum was made. Since presentation, changes in liver function were detected and subsequent study led to the diagnosis of sclerosing cholangitis. The diagnosis of ulcerative colitis was made after colonoscopy. Partial response was obtained with minocycline and clofazimine, but treatment with 5-aminosalicylic acid achieved no improvement of the ulcerations. liver transplantation, followed by immunosuppressive therapy led to complete regression of the cutaneous lesions.- - - - - - - - - - ranking = 1keywords = colitis (Clic here for more details about this article) |
8/62. Secondary sclerosing cholangitis and portal hypertension after O157 enterocolitis: Extremely rare complications of hemolytic uremic syndrome.The authors experienced an extremely rare case of secondary sclerosing cholangitis and portal hypertension developed as late complications of hemolytic uremic syndrome (HUS) owing to escherichia coli o157:H7 in a 2-year-old boy. HUS after E coli O157 infection is the most frequent cause of acute renal failure in childhood and occasionally is accompanied by extrarenal complications such as encephalopathy, cardiomyopathy, ischemic colitis, and pancreatitis. Rarely, late colonic stenosis may develop secondary to the ischemic damage. Sclerosing cholangitis and subsequent cirrhosis with portal hypertension are very uncommon as late complications of HUS. To our knowledge, such a case has not been previously reported in the literature.

9/62. Three cases of primary sclerosing cholangitis associated with ulcerative colitis; diagnostic usefulness of magnetic resonance cholangiopancreatography.BACKGROUND/AIMS: Primary sclerosing cholangitis is often accompanied by inflammatory bowel disease in western countries. However, the incidence of primary sclerosing cholangitis in patients with ulcerative colitis appears to be much lower in japan. METHODOLOGY: Between 1980 and 1998, a total of 402 patients with ulcerative colitis were seen in our department. The patients were evaluated by abdominal ultrasonography, endoscopic retrograde cholangiopancreatography, and/or magnetic resonance cholangiopancreatography when persisting abnormalities of biochemical findings suggested the presence of hepatobiliary diseases. RESULTS: Of the 402 patients with ulcerative colitis, 3 patients with primary sclerosing cholangitis were found. There were 2 men and 1 woman. One patient had left-sided colitis while 2 had total colitis. Magnetic resonance cholangiopancreatography was done in 2 of these 3 patients and demonstrated diagnostic features of primary sclerosing cholangitis. All 3 patients had intra- and extrahepatic involvement by primary sclerosing cholangitis. One male patient died due to progressive hepatic failure. The other male patient was treated with ursodeoxycholic acid, but serum alkaline phosphatase level remained above the normal range. The female patient maintained normal serum alkaline phosphatase levels without specific medication. CONCLUSIONS: Magnetic resonance cholangiopancreatography is the most safe and convincing tool for the diagnosis of coexistent primary sclerosing cholangitis in the patients with ulcerative colitis.- - - - - - - - - - ranking = 2keywords = colitis (Clic here for more details about this article) |
10/62. adenocarcinoma of the cecum as the first manifestation of ulcerative colitis complicated by primary sclerosing cholangitis and endomyocardial fibrosis.A 47-year-old male Caucasian patient, with no previous relevant medical history, presented in September 1996 with persistent right lower quadrant abdominal pain. A tumor in the cecum was identified and the patient was submitted to ileocecal resection with ileocolic anastomosis. Histological examination showed a moderately differentiated adenocarcinoma. One year later he developed bloody diarrhea, urgency, and loss of weight. Based on clinical presentation and histology of large bowel biopsies, a diagnosis of ulcerative colitis (UC) was established. The previously resected surgical specimen was reevaluated, and lesions resembling UC were identified in the nonneoplastic mucosa. High levels of alkaline phosphatase and gamma-glutamyl transferase were detected. These alterations could be traced back to 1991. Endoscopic retrograde cholangiopancreatography was performed, showing diagnostic features of primary sclerosing cholangitis (PSC), and the patient was put on ursodeoxycholic acid therapy. In March 1999, he started to have progressive dyspnea and signs of cardiac failure. Endomyocardial biopsy was performed showing extensive lesions of endomyocardial fibrosis. This case illustrates a rather silent course of UC in the presence of PSC, and supports the postulated increased risk in the development of proximally located colorectal carcinoma in these patients. Additionally, the development of endomyocardial fibrosis constituted an unexpected finding, not previously reported in this setting.- - - - - - - - - - ranking = 1keywords = colitis (Clic here for more details about this article) |
