Patient counselling and written instructions are inexpensive, safe and simple interventions. Such interventions are an effective means of optimizing colonoscopy preparation in the inpatient setting.
In Canada, budesonide has been successfully used in seven of nine patients with autoimmune hepatitis who were either intolerant to prednisone and azathioprine or prednisone-dependent. No adverse effects were reported with budesonide. Budesonide is potentially a valuable treatment option for AIH patients refractory or intolerant to standard therapy, and is deserving of further study.
Fulminant hepatic failure (FHF) refers to the rapid development of severe acute liver injury with impaired synthetic function and encephalopathy in a person who previously had a normal liver or had wellcompensated liver disease. The potential causes of FHF are numerous, but viral or toxin-induced hepatitis are the most common. Clozapineinduced hepatotoxicity has rarely been reported in the literature, occurs via an unknown mechanism and results in liver biochemical abnormalities that are usually of no clinical significance. In approximately 30% to 50% of patients treated with clozapine, there is an asymptomatic rise in serum aminotransaminase levels; however, there are no current guidelines for routine monitoring of liver function tests and liver enzymes during its use. Fatal fulminant hepatitis has only been reported in three patients receiving clozapine. A case of fatal FHF that occurred in a schizophrenic woman who began clozapine therapy shortly before her illness developed is described.
Parvovirus B19 induced acute hepatitis and hepatic failure have been previously reported, mainly in children. Very few cases of parvovirus induced hepatic failure have been reported in adults and fewer still have required liver transplantation. We report the case of a 55-year-old immunocompetent woman who developed fulminant hepatic failure after acute infection with Parvovirus B19 who subsequently underwent orthotopic liver transplantation. This is believed to be the first reported case in the literature in which an adult patient with fulminant hepatic failure associated with acute parvovirus B19 infection and without hematologic abnormalities has been identified prior to undergoing liver transplantation. This case suggests that Parvovirus B19 induced liver disease can affect adults, can occur in the absence of hematologic abnormalities and can be severe enough to require liver transplantation.
Crohn's disease is a chronic inflammatory condition that can involve any portion of the GI tract, leading to disabling symptoms and complications. Standard treatment with 5-aminosalicylic acid, antibiotics, corticosteroids and immunosuppressives has limited efficacy and is associated with serious potential adverse events. The anti-TNF-alpha agents are effective in the induction and maintenance of remission in luminal and fistulizing Crohn's disease. Recent evidence suggests that early treatment with anti-TNF agents and immunosuppressives may alter the natural history of the disease and prevent late complications. In those patients who have lost response to, or are intolerant of, a single anti-TNF agent, increasing the dose of the medication or switching to alternate biologic agents, such as another anti-TNF drug or natalizumab, have been shown to be effective treatments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
