Enteric protein loss as a marker of intestinal inflammatory activity in Crohn's disease: comparability of enteric clearance and stool concentration of alpha-1-antitrypsin?

Intestinal alpha 1-antitrypsin (alpha 1-AT) clearance has been shown a reliable index of intestinal inflammatory activity in Crohn's disease (CD). For reasons of practicability, it has been repeatedly suggested to replace alpha 1-AT clearance by alpha 1-AT concentration in random stool samples. In 60 controls and in 70 patients with CD, in 21 patients before and after treatment, fecal alpha 1-AT concentration and the ratio of stool and serum alpha 1-AT concentration were compared with alpha 1-AT clearance. In 11 patients alpha 1-AT clearance, fecal concentration and stool/serum alpha 1-AT concentration ratio were compared with 51Cr-albumin clearance. alpha 1-AT clearance (104 +/- 14 vs. 17.5 +/- 2 ml/d, p < 0.0001) as well as fecal alpha 1-AT concentration (155 +/- 21 vs. 30 +/- 3 mg/100 ml, p < 0.0001) and stool/serum alpha 1-AT concentration ratio (45 +/- 6 vs. 12 +/- 1) were significantly higher in CD patients than in controls. alpha 1-AT clearance (60 +/- 9 vs. 37 +/- 4 ml/d, p < 0.01), fecal alpha 1-AT concentration (113 +/- 21 vs. 59 +/- 8 mg/100 ml, p < 0.01) and the stool/serum alpha 1-AT concentration ratio (27 +/- 4 vs. 18 +/- 2) decreased after treatment, but fecal alpha 1-AT concentration and the stool/serum alpha 1-AT concentration ratio failed to parallel the course of alpha 1-AT clearance in 33% and in 24% of patients, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

Aortic graft-enteric fistula and paraprosthetic-enteric fistula: a review.

AGEF/PPEFs are infrequent, life-threatening complications of aortic reconstructive surgery. Early diagnosis requires a high index of suspicion. Whenever a patient with an aortic prosthesis develops gastrointestinal bleeding or manifestations of sepsis, the presence of a fistulous complex should be assumed until proven otherwise. In the vast majority of cases, adequate surgical management requires graft excision with extraanatomic bypass. Widespread retroperitoneal infection precludes any attempt at local revascularization.
