Abstract
OBJECTIVE
This study investigated the correlation between the chronological age, telomere length in peripheral blood leukocytes and blood laboratory data of female patients with mild hypertension to identify laboratory data that reflect the biological aging of individuals.
DESIGN
Cross-sectional population-based study.
SETTING
Outpatient clinic of the Department of Cardiovascular, Respiratory, and Geriatric Medicine Kyushu University Hospital at Beppu in Japan.
PARTICIPANTS
Outpatients with mild hypertension treated with a low dose of amlodipine.
MEASUREMENTS
The laboratory data of female patients were collected and the telomere length parameters in their peripheral blood leukocytes were determined by Southern blotting. Any correlations between the laboratory data and the telomere length parameters were assessed.
RESULTS
The patients showed a positive correlation between the telomere length and the high density lipoprotein, albumin, creatinine, hemoglobin levels, red blood cell counts, and a negative correlation with the globulin level. The extent of subtelomeric methylation of long telomeres tended to correlate negatively with the telomeric attrition. Only the creatinine level correlated with subtelomeric methylation, but not with telomeric length.
CONCLUSION
HDL and the albumin/globulin ratio were potential indicators for individual somatic genomic aging. Creatinine may therefore be a useful indicator for a predisposition for telomeric attrition.
