ABSTRACT
Objective:To analyze the weight score and clinical application of 2019 European League Against Rheumatism/American College of Rheumatology (EULAR/ACR) systemic lupus erythematosus (SLE) classification criteria in lupus nephritis patients.Methods:Lupus nephritis patients with renal biopsy results who were admitted in the First Affiliated Hospital of Zhejiang University College of Medicine between January 2014 and December 2018 were enrolled retrospectively. According to whether these patients were treated with glucocorticoids and/or immunosuppressants at the time of renal biopsy, they were divided into untreated group and post-treatment group. The weight scores were compared between the two groups, and the relationship between each weight score and remission after treatment was analyzed. Taking no remission as the end event, Cox regression analysis was used to analyze the influence of each weighted integral on the end event.Results:A total of 153 patients were enrolled, including 131 (85.6%) females. These were 70 (45.8%) patients in the untreated group and 83 (54.2%) patients in the post-treatment group. The patients in the untreated group had higher scores of fever (>38.3℃), blood system involvement, low complement and positive specific antibodies than those in post-treated group (all P<0.05). In a median follow-up of 34 (6-50) months, 99 patients (64.7%) achieved complete remission, 38 patients (24.8%) achieved partial remission and 16 patients (10.5%) had no remission. With no remission as the endpoint event, univariate Cox regression analysis showed that proliferative lupus nephritis (renal score of 10 points vs 8 points) and neuropsychiatric involvement were the risk factors (both P<0.05), while multivariate Cox regression analysis showed that neuropsychiatric involvement ( HR=4.758, 95% CI 1.324-17.101, P=0.017) was an independent risk factor. Conclusion:The weight scores of 2019 EULAR/ACR SLE classification diagnostic criteria have certain predictive value for remission of patients with lupus nephritis.
ABSTRACT
Objective To investigate the influence factors of left ventricular hypertrophy ( LVH) in incipient systemic lupus erythe-matosus (SLE) patients with lupus nephritis (LN).Methods A total of 210 LN patients in the authors′centre were enrolled in this cross-section study .General information , laboratory measurements , examinations of left ventricular hypertrophy by ultrasonography were col -lected.Patients were divided into two groups according to left ventricular mass index (LVMI):left ventricle thickening (LVT) group (n=89) and left ventricle normal group (n=121).General information and laboratory results of two groups were statistically analyzed .In-fluence factors of the patients were analyzed with Spearman rank correlation and multiple linear regression .Results Serum uric acid and hyper-sensitive C-reactive protein (hs-CRP) were higher in left ventricular thickening (LVT)group, as compared with those in left ventricle normal group .Hemoglobin and estimated glomerular filtration rate ( eGFR) in LVT group were significantly lower than those in left ventricle normal group (P<0.05).Spearman rank correction indicated that LVH was positively correlated with serum uric acid and hs-CRP (r=0.283、0.327, all P<0.05).LVH was negatively correlated with hemoglobin and eGFR (r=-0.232, -0.186, all P<0.05).Multiple linear regression showed hs -CRP and hemoglobin correlated with LVH (β=0.235、-0.206, all P<0.05).Conclu-sion Inflammatory state and anemia were risk factors of LVH in LN patients .
