The predictive value of serum klotho in diabetes mellitus and hypertension

Klotho allele status is associated with increased risk of cardiovascular diseases, diabetes and hypertension.

To determine if serum klotho level was lower among diabetic and hypertensive patients compared to control group. Patients and

This was a cross-sectional study of 90 participants. Thirty pure diabetic patients and 30 participants with pure hypertension were compared with the healthy control group. Multiple logistic regressions were used to examine the association between serum klotho and diabetes and hypertension. We also tested the cut off point of serum klotho to predict hypertension and diabetes by using ROC (receiver operating characteristic) curve.

The level of serum klotho was significantly lower in diabetic and hypertensive patients. Participants with higher klotho were less likely to have diabetes and hypertension [OR: 0.48, 95% CI (0.22-0.81)] even after adjustment for covariates. ROC curve for diabetes and hypertension indicated 0.8 area under the curve which was statistically significant.

This study found that serum klotho was associated with lower odds of diabetes and hypertension. Further longitudinal studies are necessary to confirm this finding.
