An Investigation of the Relationship Between Pancreas Volume, Nutritional Status, and HbA1c in Geriatric Patients.

Background and

Objectives

With physiological aging, the pancreas is expected to decrease in size as in every organ. The objective of this study was to examine the correlation between pancreas volume (PV), nutritional status, and glycolyzed hemoglobin A1c (HbA1c) in elderly patients with and without type 2 diabetes mellitus (DM). Materials and

Methods

Between July 2020 and April 2022, 109 patients aged ≥ 65 years who applied to geriatrics clinics and outpatient clinics were included in the study. PV was measured from available abdominal contrast-enhanced computed tomography (CT) scans. Patients were divided into two groups according to the presence of DM. The relationship between PV; biochemical parameters, especially HbA1c; and Mini Nutritional Assessment Short Form (MNAsf) score was analyzed between groups. p < 0.05 was considered statistically significant.

Results

The mean age of all participants was M: 77.40, with SD: 7.32. A total of 54.1% of the participants were female, and 55 had DM. There were no significant differences in age and gender between those with and without DM. Glucose (p < 0.001), HbA1C (p < 0.001), and triglycerides (p < 0.001) were significantly higher, and HDL (p < 0.001) was significantly lower in patients with DM. PV was also significantly lower in those with DM (p = 0.028). A correlation analysis revealed significant positive correlations between PV, the MNAsf score (rho (109)) = 0.413, p = 0.003), and lipase (rho (109)) = 0.297, p = 0.002).

Conclusions

PV, which is expected to decrease with age, was found to be lower in patients with DM in our study in which we evaluated elderly patients with and without DM. We also found that PV was associated with malnutrition. Our study highlights the importance of determining the clinical effects of pancreatic volume in the geriatric population where organ atrophy is expected. Therefore, we believe that more comprehensive studies are needed to clarify the clinical implications of pancreatic volume on our diagnostic and therapeutic decisions.
