Pulmonary function in patients with ulcerative colitis and its relationship with disease severity.

Background And Aim: Ulcerative colitis (UC) patients have several extraintestinal and systemic manifestations. As studies on the frequency and predictors of pulmonary involvement in patients with UC are inconsistent, we undertook this prospective study.

Methods: Eighty-seven patients with UC (in remission 49, 56.

Frequency and factors associated with increased small intestinal permeability in patients with portal hypertension.

Aim: Cirrhosis with portal hypertension (PHT) may be associated with increased small intestinal permeability (SIP), predisposing to malnutrition and bacterial translocation causing septicaemia, endotoxaemia and spontaneous bacterial peritonitis. However, data on SIP in extrahepatic portal venous obstruction (EHPVO), in which PHT occurs without hepatic dysfunction, are scanty. Such studies would help to know the effect of PHT on SIP independent of hepatic dysfunction; hence, we undertook this study.
