Study on the correlation of serum estrogen, androgen and progesterone levels in male patients with gout / 中华风湿病学杂志

ABSTRACT

Objective:To explore the changes of estrogen, androgen and progesterone in serum of male patients with primary gouty arthritis (pGA) and their possible role in the pathogenesis of gout.Methods:The serum, clinical data and laboratory parameters of 266 patients with PGA [including 93 patients with acute gout (AG), 118 patients with intermittent gout (IG), 55 patients with chronic gout (CG)] and 129 healthy controls (HC) were collected. The serum estradiol (E 2), progesterone (P), testosterone (T) and E 2/T were detected by CMIA Expression level. SPSS 17.0 statistical software was used for analysis, Wilcoxon rank sum test was used for comparison of measurement data between groups, and Spearman correlation analysis was used for correlation analysis between variables. Results:① The level of E 2 and T level in the serum of PGA, AG, IG and CG group was lower than that of the HC group [(30±8) pg/ml, (27±7) pg/ml, (31±8) pg/ml, (34±7) pg/ml, (35±10) pg/ml; F=17.770, P<0.05] and [(4.4±1.6) ng/ml, (3.8±1.4) ng/ml, (4.6±1.4) ng/ml, (5.1±2.0) ng/ml, (5.8±1.9) ng/ml; F=23.314, P<0.05], but there was no significant difference between HC group and CG group ( P>0.05), The serum E 2 and T levels in AG group were lower than those in IG and CG groups [(27±7) pg/ml, (31±8) pg/ml, (34±7) pg/ml; F=17.770, P<0.05] and [(3.8±1.4) ng/ml, (4.6±1.4) ng/ml, (5.1±2.0) ng/ml; F=23.314, P<0.05], andthe serum E 2 level in IG group was lower than that in CG group [(31±8) pg/ml, (34±7) pg/ml; F=17.770, P<0.05). The levels of P and E 2/T in HC group were lower than those in pGA and AG group [(0.24±0.10) ng/ml, (0.27±0.11)ng/ml, (0.30±0.15) ng/ml; F=5.124, P<0.05] and [(0.006 6±0.002 2) ng/ml, (0.007 6±0.003 2) ng/ml, (0.008 0±0.003 8) ng/ml; F=3.787, P<0.05), while those in IG and CG group were lower than those in AG group [(0.25±0.09) ng/ml, (0.26±0.08) ng/ml, (0.30±0.15) ng/ml; F=5.124, P<0.05]; ② Spearman correlation analysis showed that E 2 level in pGA group was positively correlated with T and CysC( r=0.310, P<0.01; r=0.164, P=0.008), negatively correlated with MO ( r=-0.133, P=0.030), P level was positively correlated with MO ( r=0.139, P=0.023), T level was positively correlated with Crea and CysC ( r=0.179, P=0.003; r=0.162, P=0.008), negatively correlated with WBC, GR and MO ( r=-0.140, P=0.022; r=-0.173, P=0.005; r=-0.149, P=0.015), E 2/T was positively correlated with apob1 and Glu ( r=0.131, P=0.032; r=0.140, P=0.023). In AG group, E 2 level was positively correlated with T and Crea ( r=0.234, P=0.024; r=0.245, P=0.018), T level was positively correlated with Crea ( r=0.349, P=0.001), and negatively correlated with apob1 ( r=-0.250, P=0.016), and E 2/T was positively correlated with apob1 ( r=0.276, P=0.007). In IG group, E 2 level was positively correlated with T ( r=0.269, P=0.003), and negatively correlated with MO ( r=-0.183, P=0.048), while P level was positively correlated with MO( r=0.204, P=0.027). Conclusion:The expression of E 2 and T in the peripheral blood serum of gout patients decreases significantly, the expression of P and E 2/T increases significantly, and there is a positive correlation between E 2 and T, as well as the inflammatory and glycolipid metabolism indexes of gout patients, suggesting that estrogen, androgen and progesterone may participate in the pathogenesis of gout by regulating the inflammation and metabolism of gout.
