ABSTRACT
Objective:To investigate the change of microalbuminuria (MA) in patients with RA and its clinical significance.Methods:From January 2018 to December 2019, data of 75 cases of RA patients were collected from outpatient and inpatient wardsof our hospital, and the data of 75 cases of physical examination wascollected as control. Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) anti-cyclic citrullinated peptide (CCP) antibody, blood lipid, Homeostasis model assessment for insulin resistance (HOMA-IR), rheumatoid factor (RF), anti-CCP antibodyand MA levels were measured respectively. RA patients were obtained by ultrasound Carotid intima-media thickness (cIMT) and brachial artery flow mediated diastolic function (FMD) were measured. The statistical analysis was carried out with independent t-test, analysis of variance, Pearson correlation analysis and multiple stepwise regression. Results:The MA level of RA patients was significantly higher than that of the healthy control group [(31±5) mg/L vs (25±4) mg/L, t=5.982, P<0.05]. In RA patients, MA level was positively correlated with course of disease ( r=0.327, P=0.015), HOMA-IR ( r=0.576, P<0.01], CRP ( r=0.212, P=0.027), RF ( r=0.585, P<0.01), disease activity score in 28 joints (DAS28) ( r=0.472, P=0.013), cIMT ( r=0.611, P<0.01) and duration of nonsteroidal anti-inflammatory drugs (NSAIDs) use ( r=0.274, P<0.01), and urineMA level( OR=1.763, P<0.01) were independent correlation factors affecting cIMT. Conclusion:The level of MA in RA patients is significantly higher than that in normal controls, and is correlated with disease activity and subclinical atherosclerosis, which could be another important predictor of disease follow-up and early screening of subclinical atherosclerosis in RA patients.
ABSTRACT
Objective To study the visfatin level changes in patients with rheumatoid arthritis (RA), and to study the correlation of visfatin level and atherosclerosis in RA.Methods Fifty cases of patients were divided to the plaque group (33 cases) and plaque-free group (17 cases) according to the carotid intima media thickness checked by carotid ultrasonography.In addition, their blood lipid level, homeostasis model assessment of insulin resistance (HOMA-IR), rheumatoid factors (RFs), anti-CCP, visfatin etc.were measured.Fifty healthy people were set as the control group.The correlation between the visfatin level of RA patients and atherosclerosis was analyzed.The statistical analysis was carried out with independent t-test,analysis of variance, Spearman correlation analysis and multiple stepwise regression.Results The serum visfatin level of RA plaques group was obviously higher than that of the plaque-free group [(47±22) μg/L vs (34±19) μg/L, t=4.361, P＜0.01].The serum visfatin level of RA patients was positively correlated to HOMA-IR (r=0.567, P=0.001), RF (r=0.502, P=0.003), anti-cyclic peptide containing citrulline, (anti-CCP) (r=0.420, P=0.038) and carotid artery IMT (r=0.596, P=0.001).High-density lipoprotein-C (OR=1.009, P=0.020), HOMA-IR (OR=1.450, P=0.006), anti-CCP (OR=1.005, P=0.014) and visfatin (OR=0.971, P=0.008) were independent relevant factors affecting carotid artery IMT.Conclusion The serum visfatin level of RA patients is closely related to atherosclerosis.
