[Analysis of serum ferritin and high sensitive C reactive protein in patients with gout]

To analyze the relationship between serum ferritin(SF) level and high sensitive C reactive protein( hs-CRP) in men and the risk of gout.

We chosed 600 male patients diagnosed with gout as gout group, 600 male patients with hyperuricemia were diagnosed as hyperuricemia group, and randomly selected 600 cases of the same period of male health examination as the control group. The detection information of physical examination and related indicators of three groups were collected, such as height, weight, serum ferritin, high sensitive C reactive protein, uric acid( UA), fasting blood glucose( FPG), triglyceride(TG), total cholesterol( TC) and so on.

Serum ferritin( SF) higher than that of hyperuricemia group 114. 45 μg/L( P<0. 05)and the control group 76. 02 μg/L( P<0. 05), while the level of hs-CRP in gout patients up to 0. 3 mg/dL, was significantly higher than that 0. 13 mg/dL in hyperuricemia group and 0. 09 mg/dL in control group( all P<0. 05). After adjusting for BMI, TG, TC, FPG and UA five confounding factors, SF was positively correlated with hs-CRP levels in the hyperuricemia group and the gout group, while there was no association between SF and hs-CRP levels in the control group. The multivariate logistic regression analysis showed that SF( ≥ 69. 01 μg/L) had significantly increased risk of HUA, after adjusting for BMI, TG, TC, FPG and UA five confounding factors, the high level of SF( ≥155. 78μg/L) had significantly increased risk of gout, with OR of 2. 678( 95% CI 1. 484-4. 833), and higher levels of hs-CRP( > 0. 9 mg/dL) was also a risk factor of gout, with OR of 3. 104( 95% CI 1. 727-5. 580). However, SF and hs-CRP were not risk factors of hyperuricemia.

Serum ferritin level and high sensitive C reactive protein levels are significantly elevated in patients with gout. It is revealed that hs-CRP, SF may be involved in the pathogenesis of gout patients.
