(HealthDay)—Acne patients have higher levels of serum homocysteine (HCY), according to a study published online Nov. 21 in the Journal of Cosmetic Dermatology.

Hao Jiang, M.D., from the First Affiliated Hospital of Guangxi University of Chinese Medicine in Nanning, China, and colleagues assessed serum HCY levels in 124 (moderate and severe) and 70 , matched for both age and sex.

The researchers found that in both male and female patients, serum HCY levels were significantly higher compared to the healthy control group (P < 0.05). Additionally, compared to the healthy controls, the ratio of male and female acne patients with HCY above the normal range (10 mmol/L) was significantly higher. There was a positive correlation between severity of acne patients and serum homocysteine concentration (P < 0.01).

"In summary, our results showed that serum HCY levels in acne patients were higher than in healthy volunteers, suggesting that dermatologists need to be aware of possible hyperhomocysteinemia in acne patients," the authors write. "Serum HCY detection for acne patients is important."
