The APACHE II severity of disease classification system has been examined prospectively in 160 patients with acute pancreatitis. Using clinical and simple laboratory data APACHE II was able to provide useful discrimination between uncomplicated, complicated and fatal attacks within a few hours of admission. Peak APACHE II scores (recorded during the first 3 days) had a prognostic accuracy similar to the multiple factor scoring systems, but then incurred a similar delay. Patients could be graded according to their risk of death or of developing a major complication; no deaths occurred in patients with a peak APACHE II score less than 10. APACHE II can be repeated daily, uncomplicated attacks demonstrating falling scores in association with clinical improvement, in contrast to the rising scores associated with clinical deterioration in those dying early. APACHE II appears to reflect any continuing disease activity and may prove a useful means of monitoring the course of the illness and response to therapy.
A number of laboratory and clinical studies have shown that interleukin-6 is the principal mediator of the acute phase protein response. In this study the relationship between serum concentrations of interleukin-6 and C-reactive protein in acute pancreatitis are examined and the ability of interleukin-6 to discriminate between severe and mild attacks is assessed. We have studied 24 patients (10 severe and 14 mild). Serum samples were collected on admission, six hourly for 48 hours and then 12 hourly for a further three days. 'When the areas under the curves of individual patients were compared there was a strong correlation between the total production of interleukin-6 and C-reactive protein (r=0.73) (Spearman rank correlation) and peak interleukin-6 and C-reactive protein concentrations (r=0-75), suggesting a close relationship between interleukin-6 and C-reactive protein production. Both on admission and peak interleukin-6 concentrations were significantly higher in patients with severe than mild disease. There was no significant difference in on admission C-reactive protein concentrations, although significant differences were seen when peak concentrations were considered. Utilising a peak interleukin-6 concentration of >130 u/ml, we were able to distinguish between severe and mild attacks of acute pancreatitis with a sensitivity of 100% and specificity of 71%. These figures were comparable with those for peak C-reactive protein, a C-reactive protein of
The present study shows that the personal costs and difficulties incurred by rural and remote residents when accessing specialist treatment can be reduced if a visiting specialist service is available.
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.
