Objective To compare the efficacy and safety of leflunomide (LEF) combined with medium/low dose corticosteroids and full dose of corticosteroids in the treatment of IgA nephropathy. Method Primary IgAN patients diagnosed by renal biopsy with 18?65 years old and eGFR≥30 ml·min?1·(1.73 m2)?1 and proteinuria>0.5 g/24 h were enrolled in a prospective controlled clinical study. They were randomly divided into leflunomide combined with medium/low dose corticosteroids (LEF group) and corticosteroids alone (steroid group). The primary outcomes were (1) end stage renal disease or dialysis (2) 50% increase in serum creatinine above the baseline. Secondary outcome was the remission of proteinuria. Results Ninety patients completed the follow?up. The 24?hour proteinuria at baseline were 2.00(1.10, 2.88) g and 1.87(1.13 ,3.08) g in LEF group and steroid group respectively. Compared with baseline, it was significantly decreased in both groups at 6 months [0.30(0.11, 0.93) g, 0.30(0.14, 1.33) g] and 12 months [0.30(0.09, 0.82) g, 0.32(0.14, 0.66) g], (P<0.05). Estimated glomerular filtration rate (eGFR) at baseline, 6 months and 12 months were (80.39 ± 28.56), (87.12±28.70) and (88.20±30.26) ml·min-1·(1.73 m2)-1. It was decreased in steroid group (P<0.05), while no significant difference was detected in LEF group[baseline (87.63 ± 27.35), 6 months (86.91 ± 32.45), 12 months (90.06 ± 30.00) ml·min-1·(1.73 m2)-1, P>0.05]. At 6 and 12 months, there was no significant difference in terms of 24?hour proteinuria, serum creatinine and eGFR (CKD?EPI) between groups (P>0.05). There was no statistically significant difference in adverse events between groups during the treatment (9/40 cases in LEF group and 11/50 cases in steroid group, P>0.05). The average follow?up was 79 months, and there was no difference in the renal prognosis between the two groups. Multivariate Cox regression analysis revealed that serum creatinine at baseline and renal interstitial inflammatory cell infiltration predicted the risk of the progress of IgA nephropathy. Conclusion Leflunomide plus medium/low dose corticosteroids has a similar effect as full dose of corticosteroids in IgA nephropathy and does not increase the risk for adverse events during the treatment.

Objective:To evaluate the short-term influence of bilateral subthalamic deep brain stimulation (STN-DBS) in anxiety symptoms and quality of life in patients with Parkinson's disease (PD).Methods:Thirty-nine PD patients underwent bilateral STN-DBS in our hospital from August 2017 to August 2018 were chosen in our study. Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI) scales were performed in these patients before and one month after surgery, and at the last follow-up, respectively. Parkinson's Disease Questionnaire-8 (PDQ-8) was performed before surgery and at the last follow-up. Statistical methods were used to analyze the differences of the above scores at different time points, and correlations between each two improvement degrees of above scores. The participants were subsequently divided into four groups based on preoperative BAI scores: no anxiety group ( n=18), mild anxiety group ( n=10), moderate anxiety group ( n=8), and severe anxiety group ( n=3); the above scales were performed. Results:(1) The BAI scores of 39 patients one month after surgery and at the last follow-up (14 [8, 20] and 9 [3, 14]) were significantly lower than those before surgery (16 [9, 27]), and the BDI scores (8[6, 16]) and PDQ-8 scores (3 [2, 6]) at the last follow-up were significantly lower than those before surgery (15 [8, 21] and 9 [6, 13], P<0.05). (2) Correlation analysis revealed that the improvement degree of BAI scores was positively correlated with that of BDI scores ( r s=0.722, P=0.000), and negatively correlated with preoperative baseline scores of BDI and PDQ-8, respectively ( r s=-0.714, P=0.000; r s=-0.378, P=0.018). (3) The BAI scores in the mild and moderate anxiety groups at the last follow-up were significantly lower as compared with the preoperative baseline BAI scores ( P<0.05). The improvement degree of BAI scores in mild, moderate, and severe anxiety groups was significantly higher than that in the no anxiety group ( P<0.05). Conclusion:The bilateral STN-DBS has considerable benefit effect on anxiety symptoms and health-related quality of life in PD patients during short-term follow-up, suggesting an involvement of STN in the pathogenesis of anxiety in PD.
