Aims:
Altered pancreatic exocrine function can be observed in patients with type 1 or type 2 diabetes. In the present study, we evaluated the potential nutritional consequences of this dysfunction.
Methods:
Serum concentrations of nutritional markers, including albumin, cholesterol, triacylglycerol, vitamins A, D, and E, were assessed in a cohort of 468 patients (137 with type 1 diabetes and 331 with type 2 diabetes), after exclusion of the patients with a CRP > 10 mg/l. These patients were compared with 47 patients with diseases of the exocrine pancreas and diabetes (type 3c diabetes or pancreatogenic diabetes). Fecal elastase-1 and chymotrypsin concentrations were measured and patients with type 1 and type 2 diabetes were divided into three groups according to whether zero (group NN), one (group LN), or both (group LL) concentrations were decreased.
Results:
Several markers differed significantly between the groups of patients, including BMI, albumin, phosphorus, and fat-soluble vitamins. Patients with pancreatogenic diabetes had markedly more profound alterations than patients with type 1 or type 2 diabetes and altered exocrine function. However, patients with type 1 or type 2 diabetes and decreased concentrations of both elastase-1 and chymotrypsin had lower albumin, phosphorus, and vitamin A than patients with normal pancreatic exocrine function.
Conclusions:
Modest nutritional alterations were found in patients with type 1 or type 2 diabetes and altered exocrine function. Patients with type 1 or type 2 diabetes and altered exocrine function may thus deserve to be screened for nutritional deficiencies.

Merocrine Secretion
Merocrine secretion is the most common type of exocrine secretion. The secretions are enclosed in vesicles and moved to the cell's apical surface, where the contents are released by exocytosis. For example, mucous, a watery secretion rich in the glycoprotein mucin, is a merocrine secretion. The eccrine...
01:13Exocrine Glands: Types of Secretions
Serous glands produce watery secretions rich in digestive enzymes and proteins. The constituent cells of the serous gland have centrally located nuclei and eosinophilic secretory granules in the cytoplasm. The parotid gland is an example of a serous gland. It secretes saliva, which contains enzymes, such as lipases and...

Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
