Fecal pancreatic elastase-1 and erythrocyte magnesium levels in diabetes type 1 and type 2.

In both types of diabetes mellitus (DM), type 1 and type 2 (T1DM and T2DM), there are both endocrine and exocrine dysfunctions of the pancreas (PED), as well as disturbances in serum magnesium levels. The aim of this study was to examine the frequency of PED according to the level of fecal elastase-1 (FE-1) in patients with T1DM and T2DM, determining the correlation of the level of FE-1 with certain anthropometric parameters, certain indicators of metabolic regulation of diabetes, and certain nutritive markers of PED.

Materials and methods: In the examinees, (56 with T1DM (F = 35 and M = 21), 62 with T2DM (F = 30 and M = 32), and 40 in the control group (F = 19 and M = 21)), we examined anthropometric parameters, and using standard biochemical methods, we measured the level of FE-1, magnesium concentration in blood and erythrocytes, and selected blood parameters.

Results: FE-1 concentration < 200 μg/g was present in 14.2% of the examinees with T1DM, 20.9% with T2DM, and 2.5% in the control group. In all examinees with DM, there was a statistically significant correlation (P < 0.05) between the level of FE-1 and Mg concentration in the erythrocytes (R = 0.40).

Conclusions: Prevalence of pancreatic exocrine insufficiency (PEI), according to the level of FE-1, is significantly higher in patients with DM than in the control group, while it is a bit higher in patients with T2DM than the ones with T1DM. In both types of DM, Mg concentration in erythrocytes is in a significant correlation with the level of FE-1.
