OBJECTIVES: Recent studies have highlighted the role of oxidative stress in the pathogenesis of lichen planus (LP). In the present study the interest of the authors is focused on the investigation of ascorbic acid status in patients with LP and identification of parameters that might influence the level of this vitamin.

MATERIAL AND METHOD: We analyzed the level of urinary ascorbic acid (reflectometric method) in 77 patients with LP (cutaneous LP (CLP) - 49 cases, oral LP (OLP) - 28 cases) and 50 control subjects. The evaluation of all participants included clinical examination and laboratory and imaging tests.

RESULTS: Compared to the control group (19.82 mg/dl) the level of ascorbic acid was significantly lower both in patients with CLP (8.47mg/dl, p = 0.001) and in those with OLP (8.04 mg/dl, p = 0.001). In patients with LP it was found that the deficiency of ascorbic acid increases with age (r=-0.318, p=0.032). The urinary concentrations of ascorbic acid were significantly lower in patients with LP associated with infections compared to patients with LP without infections.

CONCLUSIONS: The urinary ascorbic acid level may be a useful parameter in identifying patients with LP who are at risk of developing viral or bacterial infections.
