Introduction: Oxidative stress has been associated with primary dysmenorrhea, but studies that have assessed multiple markers of peroxidation are scarce. This study investigated malondialdehyde (MDA), nitrotyrosine (3-NT), and protein carbonyls (PrCarb) as markers of oxidative stress and antioxidant status by serum alpha tocopherol level in young Nigerian women with dysmenorrhea. Materials and Methods: In a case–control design, 45 female undergraduates who had had regular menses for at least six previous cycles were recruited consecutively from a university clinic as cases and 45 apparently healthy age-matched counterparts in their hall of residences as controls. Serum levels of MDA, 3-NT, and PrCarb were determined using standard methods, and the values were compared between cases and controls using Mann–Whitney U-test and graphs. Results: Study participants' ages range from 16 to 29 years (mean = 22.0 ± 3.1 years). Serum level of 3-NT (45.89 ± 37.11 vs 21.27 ± 13.94 ng/mL) and MDA (0.75 ± 0.19 vs 0.45 ± 0.11 nmol/mL) was significantly higher in cases than controls. Plasma alpha tocopherol was significantly lower in cases (7.51 ± 1.95 μmol/L) than controls (8.98 ± 1.95 μmol/L). Conversely, PrCarb levels were not significantly difference between cases and controls. There were significant correlations between alpha tocopherol and 3-NT (r = −0.285; P = 0.007) and MDA (r = −0.321; P = 0.002), whereas this relationship was not shown with PrCarb (r = −0.073; P = 0.496). Conclusion: Remarkable lipid and protein peroxidation observed in young Nigerian women with dysmenorrhea was accompanied by correspondingly low level of serum alpha tocopherol suggesting potential need for vitamin E supplementation.
