[Validation of a prognostic index through nutritional status indicators in patients with severe acute pancreatitis]

To evaluate the accuracy of a previously proposed prognostic index of mortality determined by nutritional indicators in patients severe acute pancreatitis. Methods (study population, subjects, intervention): We evaluated used three nutritional status indicators (total lymphocyte count, creatinine/height index and subescapular skinfold) to determine an index associated to mortality prognosis in patients with severe acute pancreatitis.

We assessed 34 patients, who were divided according to their outcome into: a) survivor, b) dead. The vast majority showed a litiasic origin of the disease, which was present among men, predominantly. The index' results were found to be directly (positively) related to mortality probability, i.e., the closer the score was to 2,the more probability the patient had to die.

Even though we were able to prove association between the proposed index and the patient's prognosis, a larger sample is needed to validate this as a possible tool which could be used along other prognostic test such as APACHE II or Ranson scales.
