OBJECTIVES Tetrahydrobiopterin (BH4), a cofactor of nitric oxide synthase, might have a role in the treatment of portal hypertension (PHT) as its administration improves endothelial nitric oxide generation and hepatic endothelial dysfunction, and reduces portal pressure in experimental models of cirrhosis. Sapropterin is an oral synthetic analogue of BH4(More)
BACKGROUND The availability of a quantitative method to measure anti-infliximab (IFX) antibodies (ATI) would facilitate the implementation of therapeutic drug monitoring in clinical decision-making. Our aim was to standardize the homogeneous mobility shift assay (HMSA) used in the measure of ATI levels. METHODS In this prospective longitudinal multicenter(More)
Obesity increases the risk of clinical decompensation in cirrhosis, possibly by increasing portal pressure. Whether weight reduction can be safely achieved through lifestyle (LS) changes (diet and exercise) in overweight/obese patients with cirrhosis, and if weight loss reduces portal pressure in this setting, is unknown. This prospective, multicentric,(More)
Inflammatory bowel disease (IBD) patients in remission may suffer from gastrointestinal symptoms that resemble irritable bowel syndrome (IBS). Knowledge on this issue has increased considerably in the last decade, and it is our intention to review and summarize it in the present work. We describe a problematic that comprises physiopathological(More)
BACKGROUND Anti-TNF treatment is effective for Crohn's disease (CD); however, some patients did not achieve remission with these drugs. AIMS To evaluate the short-term effectiveness of a second anti-TNF in CD patients who did not achieve remission with the first one and to assess its durability. METHODS Patients who did not achieve remission with their(More)
Many drugs can produce enterocolitis and they should always be included in the differential diagnosis of this clinical picture. Entities such as antibiotic-associated colitis and neutropenic colitis have been known for some time and recently a new type of drug-induced colitis has emerged due to monoclonal antibodies. Ipimumab is a humanized monoclonal(More)
