RESUMO
Objective:To investigate the clinical features and influencing factors of renal artery involvement in patients with Takayasu's arteritis (TA).Methods:One hundred and five TA patients were included and their clinical features, laboratory tests, echocardiographic findings were collected and analyzed. The t-test, Mann-Whitney U test, Sperman's correlation and logistic regression were used for statistical analysis. Results:Of the 105 patients with Takayasu's arteritis, 21 (20%) patients were diagnosed to have renal artery involvement. They had higher frequency of hypertension [76%(16/21) vs 25%(21/84); χ2=19.291, P<0.01], syncope [19%(4/21) vs 4%(3/84); P=0.028] and headache [52%(11/21) vs 25%(21/84); χ2=5.944, P=0.019]. Patients with renal artery invol-vement had higher levels of creatinine [(67±30) mmol/L vs (50±14) mmol/L; t=2.436, P=0.023], lower levels of lymphocyte subsets CD3 +[1 299(1 261.5, 1 313.45)/μl vs 1 531 (1 330, 1 559.5)/μl; Z=-3.12, P=0.002], CD4 +[793.6(715, 804.32)/μl vs 914.88(794.3, 914.8)/μl; Z=-2.597, P=0.009], CD8 +[451.09(451.09, 489.5)/μl vs 552.39(459.75, 557.5)/μl; Z=-3.271, P=0.001] and glomerular filtration rate ( Z=-2.612, P=0.009). Comparison of echocardiographic parameters between the two groups showed that the diameters of left atrium [(35±4) mm vs (32±4) mm; t=3.065, P=0.003] and end-diastolic left ventricular [49.2(47.5, 52.5) vs 45.84(43.25, 47.75); Z=-3.795, P<0.01] were larger in renal artery involvement group. Abdominal aorta ( χ2=14.292, P<0.01), superior mesenteric artery ( P<0.01), inferior mesenteric artery ( P=0.038) and common iliac artery ( P=0.005), were more likely involved in patients with renal artery involvement; while the common carotid artery ( χ2=3.815, P=0.047) and subclavian artery ( P=0.022) were less affected. There was a positive correlation between creati-nine level ( r=0.282, P=0.004) and renal artery involvement in patients with arteritis, and the number of lymphocyte subsets (CD3, CD4, CD8) ( r=-0.306, P=0.002; r=-0.255, P=0.009; r=-0.321, P=0.001) was negatively correlated with renal artery involvement. Conclusion:The most common pattern of renal artery involvement is stenosis and occlusion. Hypertension, syncope, headache, kidney dysfunction and heart failure are more prevalent among patients with renal artery involvement. The number of lymphocyte subsets is low, and involvement of abdominal aorta is common. It should be assessed and treated as soon as it is discovered.
RESUMO
Objective To study the mental status and its influencing factors of patients with rheumatic disease. Methods Three hundreds and eighty-one patients with rheumatic diseases were assessed with the self-rating anxiety scale, self-rating depressive scale, Eysenck Personality Questionnaire symptom checklist-90, and demographic characteristics questionnaire. The comparison among groups were tested by t tests, Spearman's correlation analysis. Results Patients with anxiety symptoms accounted for 35.96%, and pre-valence rate of depression was 48.03%. The gender (r=0.87, OR=2.34) and duration (r=0.006, OR=1.006) were the risk factors and the C4 (r=-2.63, OR=0.07) was the protective factor. In patients with systemic lupus erythematosus, depression was related to education (Z=2.228, P=0.026), disease duration (Z=-2.015,P=0.044), IgG level (t=-2.266, P=0.027), T cell subsets CD8 (Z=1.981, P=0.047) and CD3 (Z=1.967, P=0.049). Anxiety was related to education (Z=2.452, P=0.014), duration (Z=-2.054, P=0.04), complement C3 (t=2.035, P=0.045), C4 (Z=-2.204, P=0.028) and IgG level (t=-2.126, P=0.036). The value of CRP(Z=-1.984, P=0.047) and IgM (t=2.243, P=0.028) of rheumatoid arthritis patients were higher in the depression group. The depression group was different in disease duration (Z=-2.631, P=0.009), gender ( χ2=4.415, P=0.042), ESR (Z=2.17, P=0.023) and CD3 cell (Z=2.023, P=0.043) in Sj?gren's syndrome patients. Correlation analysis showed positive correlation between the score of SDS, SAS and the P value (r=0.21, P=0.01) (r=0.14, P=0.007) N dimension (r=0.52, P=0.01) (r=0.55, P=0.007) of EPQ. There were negative correlation between the score of SDS, SAS and the E dimension (r=-0.23, P=0.01) (r=-0.14, P=0.006) of EPQ. Conclusion The prevalence of depres-sion and anxiety is higher in patients with depressive and anxious symptoms. They are in older age, female gender, poor education, longer duration, lower complement and lower T cell subsets when compared with those patients without depression and anxiety. Patients who have an introverted, instable, nervous temperament are more likely to be depressed and anxious. Psychological assessment intervention and therapy should be carried out as early as possible.
