ABSTRACT
Objective To explore the influence of different doses and courses of colchicine on tumor markers in patients with gouty arthritis.Methods Totally 102 patients with acute gouty arthritis were divided into group 1 (had taken colchicine before in hospital)and group 2 (hadn't taken colchicine before in hospital).Group 2 was divided into two subgroups,group 2A and group 2B.We also included 31 cases of non-gouty arthritis patients in the same period in the hospital as control group.Group 2A and group 1 were given 0.5 mg bid of colchicine and corresponding NSAID on the day admitted to hospital.Group 2B were given the same dose of colchicine the next day.Blood sedimentation,c-reactive protein,serum creatinine,blood uric acid,CA724,AFP,CEA,CA125,CA153 and CA199 were detected in all patients on the next day admitted to hospital.Then we analyzed the differences and influencing factors among the groups.Retest CA724 1 week later,and follow-up parts of patients,reevaluate CA724 again after stopping using colchicine.Results Compared with the control group,CA724 significantly elevated in patients who took colchicine,and the difference was statistically significant.CA724 level of day 1 in group 2A was obviously higher than that of group 2B,and the difference between the two groups was statistically significant.It showed that very low dose colchicine can also result in higher CA724,and the level was closely relative to total dose and using course.After stopping drug,CA724 value can drop to normal range.Conclusion Colchicine can significantly affect the level of serum CA724,which gradually rise with the increase of drug dose and course.It can be back to normal after drug withdrawal.The discovery can avoid the clinical misdiagnosis and excessive medical treatment,It has certain guiding significance.
ABSTRACT
Objective To study the correlation between fractional excretion of uric acid (FEUA) and blood uric acid,body mass index (BMI),blood pressure,blood glucose,blood lipid and other metabolic factors in patients with primary gout.Methods Sixty-two patients with primary gout (gout group) and 32 healthy people (control group) were selected in this study.Gout group was divided into uric acid excretion decreasing group (FEUA ＜ 7％,29 cases),mixed group (7％ ≤FEUA ≤ 12％,25 cases) and uric acid production increasing group (FEUA ＞ 12％,8 cases) according to the level of FEUA.The fasting blood glucose (FPG),2-hour postprandial blood glucose (2 h PBG),blood lipid,serum creatinine,blood uric acid,glycosylated hemoglobin were tested.24 hours urine was collected and urinary uric acid and urinary creatinine was measured,FEUA was calculated and analyzed.Results BMI,mean arterial pressure,blood uric acid,glycosylated hemoglobin,total cholesterol,2 h PBG in gout group was higher than that in control group,and high density lipoprotein cholesterol,FEUA was lower than that in control group,and there was significant difference (P ＜ 0.05).There was no significant difference in age,FPG,low density lipoprotein cholesterol,triacylglycerol between two groups (P＞ 0.05).There was no significant difference in age,blood uric acid,FPG,2 h PBG,glycosylated hemoglobin,total cholesterol,low density lipoprotein cholesterol,high density hpoprotein cholesterol among uric acid excretion decreasing group,mixed group and uric acid production increasing group (P ＞ 0.05),and there was significant difference in BMI,mean arterial pressure,triacylglycerol,FEUA among three groups(P＜ 0.05).FEUA was negatively correlated with blood uric acid in control group and gout group (r =-3.900,-0.476,P ＜0.05).FEUA was positively correlated with 24 h urinary uric acid in gout group (r =0.465,P =0.001),and nagatively correlated with triacylglycerol (r =-0.304,P ＜ 0.05).Pearson analysis showed that FEUA was negatively correlated with blood uric acid in uric acid excretion decreasing group (FEUA ＜ 7％) (r =-0.392,P ＜ 0.05),FEUA was positively correlated with blood uric acid in non uric acid excretion decreasing group (FEUA ≥7％)(r =0.437,P ＜ 0.05),but 24 h urinary uric acid was not correlated with blood uric acid(P ＞ 0.05).Multi-stepwise regression analysis showed that blood uric acid,glycosylated hemoglobin,FEUA was significantly correlated with the onset of the gout (P ＜ 0.05).Conclusions Besides blood uric acid level,there are significant changes in primary gout in blood pressure,serum glucose and lipid levels.FEUA could be used to estimate the ability of renal excrete the uric acid.Mean arterial pressure,glycosylated hemoglobin and FEUA are the risk factors for gout.
