[Nutritional status assessment in diabetes mellitus secondary to chronic alcoholic pancreatitis].

BACKGROUND
Diabetes mellitus secondary to alcoholic chronic pancreatitis (DM-ACP) represents 0.5-2% of all cases of diabetes mellitus (DM) and shows predominantly symptoms related to malnutrition instead of cardinal clinical signs of diabetes. The aim of this study was to try to further characterize the features of the malnutrition in patients with pancreatic insufficiency. PATIENTS MATERIAL AND METHODS: We selected 40 patients (39 males and 1 female) meeting clinical, functional and morphological diagnostic criteria of DM-ACP which received a nutritional assessment that included estimation on fat and proteic body compartments being classified as caloric, proteic or mixed malnutrition.


RESULTS
29 patients (72.5%) showed some kind of malnutrition. The most frequent type was mixed (proteic-caloric) malnutrition found in 19 of them (47.5%). Caloric malnutrition was present in 6 (15%) and mainly proteic in 4 (10%). Only 11 patients with DM-ACP in our series showed a normal nourishment state.


CONCLUSIONS
Large prevalence of mixed malnutrition in DM-ACP patients may be related to malabsorption of macronutrients (especially proteins and fat) due to exocrine insufficiency and misuse of nutrients as a result of the characteristic hypoinsulinemia showed by these patients.
