An unusual case of an ulcerative colitis flare resulting in disseminated intravascular coagulopathy and a bladder hematoma: a case report

A Patient with Ulcerative Colitis Complicated by Systemic Vein Thrombosis

Crohn's disease and ulcerative colitis (UC) patients have an increased risk for thromboembolic complications, the most common of them are deep venous thrombosis and pulmonary embolism. Other locations and genetic mutations of coagulation factors are not so common in these patients. Here we present a case of a young woman with exacerbation of previously diagnosed mild UC complicated by multiple thrombotic incidents due to MTHFR gene mutation.

Protective effect of magnesium lithospermate B against dextran sodiumsulfate induced ulcerative colitis in mice

Anti-platelet drugs have been used to treat inflammatory bowel disease. In this study, we observed the therapeutic effects of magnesium lithospermate B, a main component of salvianolate, on colitis induced by dextran sodiumsulfate (DSS). Colitis was induced by 5% DSS oral administration in BALB/C male mice. Magnesium lithospermate B (60-240mg/kg) was given by subcutaneous injection for 2 weeks. Then, mice were sacrificed; serum and colon tissues were collected for biomarker assay, histological examination, immunohistochemical study and real-time quantitative polymerase chain reaction. DSS induced gross bleeding, inflammation, crypt damage and mucosal damage in colon. Treatment with magnesium lithospermate B could reduce colon inflammation induced by DSS. Magnesium lithospermate B could reverse the high CD40/CD40L expression and hypercoagulable state induced by DSS in colon. This study showed that magnesium lithospermate B could be used to treat colitis. The protective effects of magnesium lithospermate B may be due to its effects on CD40/CD40L expression and blood clotting status.

A case study of acute fulminant ulcerative colitis complicated with idiopathic thrombocytopenic purpura

A 19-year-old man was admitted to hospital due to a fever for two weeks and hematochezia for 8 days. A diagnosis of acute fulminant ulcerative colitis (UC) was established, based on clinical features, X-ray and colonoscopy. He was diagnosed as idiopathic thrombocytopenic purpura (ITP) according to clinical features, thrombocytopenia and bone marrow aspiration at the same time. ITP associated with fulminan UC is relatively rare.
