Consecutive patients with CP were randomly assigned to receive placebo or antioxidant supplementation for 6 months, with the main endpoint of the study being pain relief. Secondary endpoints were a need for analgesics and hospitalization. Oxidative stress markers measured were thiobarbituric acid–reactive substances and antioxidant status (ferric-reducing ability of plasma).) G& W) ]; D+ D2 K

Mean age of the patients was 30.5 ± 10.5 years, 86 were men, 35 had alcoholic CP, and 92 had idiopathic CP. Of 127 patients randomly assigned, 56 were in the placebo group and 71 in the antioxidant group. Compared with the placebo group, the antioxidant group had a significantly greater decrease after 6 months in the number of painful days per month (7.4 ± 6.8 vs 3.2 ± 4 days, respectively; P < .001; 95% confidence interval [CI], 2.07 - 6.23).tvb now,tvbnow,bttvb7 u/ [( Q' n9 E2 Q

The proportion of patients that became pain-free was 32% in the antioxidant group and 13% in the placebo group (P = .009). & z1 P6 i; K% F1 G公仔箱論壇TVBNOW 含有熱門話題,最新最快電視,軟體,遊戲,電影,動漫及日常生活及興趣交流等資訊。- {' e4 w1 p% t!

Compared with the placebo group, the antioxidant group had a significantly greater reduction in the level of thiobarbituric acid–reactive substances and an increase in the ferric-reducing ability of plasma (thiobarbituric acid–reactive substances: placebo, 1.2 ± 2.7 nmol/mL vs antioxidant, 3.5 ± 3.4 nmol/mL; P = .001; 95% CI, 0.96 - 3.55; ferric-reducing ability of plasma: placebo, –5.6 ± 154.9 μMFe+2 liberated vs antioxidant 97.8 ± 134.9 μMFe+2 liberated; P = .001; 95% CI, 44.98 - 161.7). 2 U/ K& g: @: N: r " [6 F i! o; v- E6 Y" x"Antioxidant supplementation was effective in relieving pain and reducing levels of oxidative stress in patients with CP," the study authors write.

Limitations of the study include evaluation of pain subject to bias, reduction of pain in the placebo group, loss to follow-up, and lack of data concerning for how long the effect of antioxidants will last and for how long the antioxidant supplementation should be continued.

"This could be due to the fact that the patients were antioxidant deficient. We believe that antioxidant therapy can be prescribed in an appropriate clinical setting of CP."公仔箱論壇# y!
