Assessment of serum and salivary visfatin levels in newly diagnosed patients of type-II DM.

BACKGROUND

Type II diabetes mellitus (T2DM) is a metabolic disorder. It is thought to be an autoinflammatory disease, as inflammatory mediators are associated with the progression of the disease. Visfatin, an adipokine, is linked to insulin resistance.

AIMS

We aimed to study serum and salivary visfatin levels, at the time of diagnosis of T2DM, in middle-aged individuals, in the context of other diagnostic parameters like fasting blood sugar (FBS), postprandial blood sugar (PPBS), and glycated haemoglobin A1c (HbA1c).

MATERIALS AND METHODS

Thirty newly diagnosed T2DM (Group-I, T2DM) patients and 30 healthy nondiabetic individuals (Group-II, health controls [HC]) matched for age and sex were studied. In both the groups, we assessed serum and salivary visfatin levels, and serum high-sensitivity C-reactive protein (hs-CRP) levels. We also compared serum and salivary visfatin levels and serum hs-CRP levels between Group-I and Group-II individuals.

STATISTICAL ANALYSIS

The correlation between the groups was tested using Pearson's correlation. A value < 0.001 was considered to be statistically significant. The data was tabulated using software MS Excel and analysed using IBM Statistical Package for the Social Sciences (SPSS) Version 22.0.

RESULTS

A positive correlation with a value of 0.8836 and a value of 0.001 was noted between serum and salivary visfatin of Group-I.

CONCLUSION

This is the first study in the Indian scenario to study the serum and salivary visfatin in newly diagnosed T2DM individuals. Serum visfatin and hs-CRP levels increased in T2DM, thus defining the link between visfatin, inflammation and T2DM, but we failed to notice a positive correlation.
