Cardiovascular risk markers in premature canities

Area of Science:

• Cardiovascular Health
• Dermatology
• Endocrinology

Background:

• Premature hair greying (canities) before age 30 is associated with elevated cardiovascular risk.
• Chronic inflammation, indicated by elevated interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α), is linked to cardiovascular risk but unstudied in early canities.
• This study investigates cardiovascular risk markers in patients with premature canities.

Purpose of the Study:

• To assess cardiovascular risk markers, including pro-inflammatory cytokines (IL-6, TNF-α), in individuals with premature canities.
• To compare these markers between patients with premature canities and age/gender-matched controls.

Main Methods:

• A case-control study involving 40 patients (19-25 years) with premature canities and 40 healthy controls.
• Measurements included blood pressure, pulse rate, body mass index, fasting blood sugar, serum insulin, lipid profile, hs-CRP, IL-6, and TNF-α.
• Homeostatic model assessment of insulin resistance (HOMA-IR) was calculated.

Main Results:

• Patients with premature canities showed significantly higher blood pressure, fasting blood sugar, serum insulin, hs-CRP, and HOMA-IR compared to controls.
• Serum HDL levels were significantly lower in the premature canities group.
• Elevated IL-6 levels were observed in a greater proportion of patients with premature canities.

Conclusions:

• Abnormal cardiovascular risk markers are present in patients with premature canities.
• The study highlights a link between early hair greying and underlying metabolic and inflammatory abnormalities.
• Screening and counseling for cardiovascular disease risk are recommended for individuals with premature greying.
