| description | Introduction: Type 2 Diabetes Mellitus (T2DM), a common
metabolic disorder characterised by hyperglycaemia is caused
due to an absolute or relative insulin deficiency and/or insulin
resistance. Vitamin D, a steroid hormone beyond its primary
role on calcium and bone metabolism, also has been shown to
have multiple other effects. Vitamin D levels have been studied
in relation to glucose metabolism as role in insulin secretion and
insulin resistance by many studies in the past.
Aim: To estimate the levels of serum 25-OH vitamin D and to
correlate with glycaemic status among uncontrolled T2DM
patients.
Materials and Methods: A case-control study was conducted
during August-September 2021 at Melmaruvathur Adhiparasakthi
Institute of Medical Sciences and Research in Melmaruvthur, Tamil
Nadu, India. In this study, 50 cases (uncontrolled T2DM) and 50
controls (healthy individuals), of both sexes aged between 40-
60 years were included. Blood samples were analysed for serum
25-OH cholecalciferol (Vitamin D), fasting and postprandial plasma
glucose levels and statistical analysis was done by Independent
sample t-test for significance testing, odds ratio for exposureoutcome association by logistic regression and Pearson coefficient
for correlation using Statistical Package for the Social Sciences
(SPSS) software version 18.0.
Results: Serum 25-OH vitamin D levels were significantly {p<0.005
(t=-9.005)} lower in cases {31.02±7.51 ng/mL} when compared
to controls {48.30±11.29 ng/mL}. Logistic regression showed
none of the predictor variables studied showing significant
outcome association (p<0.05) for vitamin D predeficiency while
Pearson correlation showed significant negative correlation with
fasting (r=-0.463) and postprandial plasma glucose (r=-0.568),
respectively at 0.01 level (2-tailed).
Conclusion: Serum 25-OH Vitamin D levels were significantly
lower and have significant inverse association with fasting
plasma glucose levels and postprandial plasma glucose levels
in uncontrolled T2DM patients. This substantiates the role of
vitamin D in maintaining normal plasma glucose levels in T2DM
patients. It is thereby proposed that serum 25-OH vitamin D
levels be measured and followed-up for better glycaemic control
among T2DM patients. |
