[Cost of early management of chronic inflammatory intestinal disease].

OBJECTIVES: The aim of this study was to assess the cost of the first management of inflammatory bowel disease (IBD) from the onset of first symptoms until 6 weeks after the diagnosis. This cost was calculated in French francs (FF) for all IBD and namely for Crohn's disease (CD), ulcerative colitis (UC), and ulcerative proctitis (UP). MATERIAL AND METHODS: Data concerning 258 patients were collected by the mean of a standardized questionnaire from 3 different sources: the patient, his general practitioner, and his gastroenterologist. RESULTS: Two hundred and fifty eight patients were included: 144 CD (55.8%), 76 UC (29.5%), 30 UP (11.6%), and 8 chronic unclassifiable colitis (CUC) (3.1%). The mean direct costs of the diagnosis (m +/- SD) were 23,116 +/- 40,820 FF for CD, 10,628 +/- 17,316 FF for UC and 3,451 +/- 2,743 FF for UP. Although unplanned hospitalizations occurred in only 38% of the patients (98/258), they represented the 3/4 of the mean costs: 78.2% for CD and 64% for UC. Indirect costs generated by days off work were 4,719 +/- 6,610 FF for CD, 2,996 +/- 6,897 FF for UC and 1,230 +/- 3,622 FF for UP. CONCLUSION: The first management of a patient with CD was twice more expensive than the one with UC and 6.5 times than the one with UP.

Enteral nutrition modifies gut-associated lymphoid tissue in rat regardless of the molecular form of nitrogen supply.

BACKGROUND: It has been suggested that beneficial effect of elemental enteral diets in the treatment of inflammatory bowel diseases could be mediated by the suppression of protein dietary antigens. The objective of the present work was to study the effect of enteral diet on gut associated lymphoid tissue and on gastric Lactobacillus flora, in rat. METHODS: The effects of three molecular forms of nitrogen supply: amino acids, oligopeptides or whole casein, were compared in rats on continuous enteral diet. Frozen sections of small bowel were studied with monoclonal antibodies anti-CD5, -CD4, -CD8, -CD25, -macrophages, -MHC II. The Lactobacillus flora was also enumerated in the stomach, in order to assess the effect of ED on rat flora. RESULTS: Growth and mucosa morphology were identical in control and enteral groups. Rats on enteral diet showed, whatever was the molecular form of nitrogen supply, a decrease in CD5+, CD4+ and CD8+ intraepithelial cell numbers, but not in lamina propria cell number, and a decreased MHC II epithelial expression, when compared to control rats. The enterally fed rats also showed a decrease in Lactobacillus gastric contents. CONCLUSIONS: The current study demonstrates that continuous enteral nutrition modifies MHC II epithelial expression and gut associated lymphoid tissue cell number in rat, whatever is the molecular form of nitrogen supply. Intestinal flora could be responsible, at least for part, for these results.

[Compared efficiency of three strategies of management of chronic hepatitis C. Effect on the risk of cirrhosis 8 years after diagnosis].

OBJECTIVES AND METHODS: The goal of treating chronic hepatitis C with alfa interferon is to eradicate HCV infection. The actual influence of this treatment on the development of cirrhosis is unknown. Moreover, the poor results and the high cost of this treatment have caused a public health problem. Three strategies were evaluated by decision analysis: no treatment (S1), treatment of chronic active hepatitis only (S2), treatment of all chronic hepatitis (S3). For each strategy, we estimated the probability of the occurrence of the following events based on data in the literature: presence of chronic active hepatitis, chronic persistent hepatitis or cirrhosis at the time of diagnosis; discontinuation of interferon because of adverse events; biological response to treatment; incidence of cirrhosis 8 years after diagnosis without treatment or in case of response to treatment. RESULTS: The risk of cirrhosis was 28.5% with S1, 25.4% with S2, and 25.2% with S3, 8 years after diagnosis. If HCV infection was detected early before cirrhosis, the number of cases of cirrhosis occurring in an 8 year-followup period would be 45,600 with S1, 40,640 with S2, and 40,320 with S3 and the cost of S2 and S3 would be 1.23 10(9) French Francs (FF), and 2.57 10(9) FF, respectively. The mean cost to prevent one case of cirrhosis would vary from 248,000 FF with S2 to 487,000 FF with S3. CONCLUSION: This decision analysis study suggests that the S3 strategy is not suitable for a population of HCV infected patients, because of its low efficiency and high cost.

[Upper digestive hemorrhage in patients over 80 years of age: incidence and prognostic factors].

OBJECTIVES: The aim of this study was to assess the incidence and the prognosis of upper gastrointestinal hemorrhage in patients aged over 80 years. METHODS: Between January and December 1993, among 360 patients admitted for upper gastrointestinal hemorrhage, 63 were older than 80 years (18%). Data were prospectively collected in all patients. RESULTS: Before admission, 8 experienced a lipothymia and 3 a shock. The median initial hematocrit was 29%. Endoscopy was performed in 59 patients and a cause was determined in 49 (83%). The main cause of bleeding was gastric and duodenal ulcer (n = 26, 53%) and ten of them were graded Forrest < or = IIb. Endoscopy did not contribute in 10 patients and was impossible in 4 because of an hemodynamic failure. Gastrotoxic drugs intake was found in 28 patients: non steroidal anti-inflammatory drugs (n = 14) and aspirin (n = 14). Endoscopic injection therapy was performed in the 10 patients with gastric or duodenal ulcer < or = Forrest IIb and permanent hemostasis was achieved in 8 out of 10. No further bleeding was seen in 53 patients (84%), while bleeding persisted in 4 and rebleeding occurred in 6 (9.5%) (3 duodenal ulcers, 2 gastric carcinomas and 1 esophageal varices bleeding). Only one patient required emergency surgery (rebleeding duodenal ulcer). The overall mortality was 12/63 (19%):50% of the deaths were related to hemorrhagic complications and 50% to concomitant disease. Only one patient among those taking gastrotoxic drug died from bleeding. The risk factors of death from bleeding were: initial shock (P = 0.02), lipothymia before admission (P = 0.02), rebleeding (P < 0.01), persistence of bleeding (P < 10(-4)). Gastrotoxic drugs intake was associated with a favorable prognosis (P < 0.05). The prognosis was not significantly affected by an initial hematocrit < 30% or blood units transfused > or = 4. CONCLUSIONS: People older than 80 years account for a large proportion of upper gastrointestinal bleeding (18%). The more common cause is gastric or duodenal ulcer. Mortality in these patients is high (19%). An initial shock or lipothymia, rebleeding or persistence of bleeding worsens prognosis. Gastrotoxic drugs intake is frequent (44%), but is associated with a good prognosis.
