This study aimed to evaluate the efficacy and safety of mycophenolate mofetil (MMF) or tacrolimus (TAC) compared with azathioprine (AZA) as maintenance therapy for active lupus nephritis (ALN). Patients with ALN who responded to 24 weeks of induction treatment were enrolled. Patients who received MMF or TAC as induction therapy continued MMF or TAC treatment during the maintenance period, whereas those who received intravenous cyclophosphamide were subjected to AZA treatment. The primary endpoint was the incidence of renal relapse. Secondary endpoints included extrarenal flares and composite endpoints (deaths, end-stage renal disease, or doubling of serum creatinine levels). A total of 123 ALN patients (47 in the MMF group, 37 in the TAC group, and 39 in the AZA group) were enrolled. The median follow-up time was 60 months. Ten MMF-treated patients, ten TAC-treated patients, and eight AZA-treated patients experienced renal relapses (P = 0.844). The cumulative renal relapse rates in the MMF group (P = 0.934) and TAC group (P = 0.673) were similar to the renal relapse rate in the AZA group. No significant difference in the incidence of severe adverse event was observed among the groups. Long-term maintenance therapies with MMF or TAC might have similarly low rates of renal relapse and similar safety profiles compared with AZA.

Objective To compare the 5-year survival rates between two different follow-up patterns of postoperative stage Ⅰ-ⅢA non-small cell lung cancer (NSCLC) patients. Methods Pathological stage Ⅰ-ⅢA NSCLC 11 958 patients who underwent surgical resection and received follow-up within 6 months after initial diagnosis through telephone follow-up system were included in nine hospitals from July 2014 to July 2020. The patients were divided into two groups including a proactive follow-up group (n=3 825) and a passive follow-up group (n=8 133) according to the way of following-up. There were 6 939 males and 5 019 females aged 59.8±9.5 years. The Kaplan-Meier and Cox proportional hazards regression model were used. Results The median follow-up frequency was 8.0 times in the proactive follow-up group and 7.0 times in the passive follow-up group. The median call duration was 3.77 minutes in the proactive follow-up group and 3.58 minutes in the passive follow-up group. The 5-year survival rate was 81.8% and 74.2% (HR=0.60, 95CI 0.53-0.67, P<0.001) in the proactive follow-up group and the passive follow-up group, respectively. Multivariate analysis showed that follow-up pattern, age, gender and operation mode were independent prognostic factors, and the results were consistent in all subgroups stratified by clinical stages. Conclusion The proactive follow-up leads to better overall survival for resected stage Ⅰ-ⅢA NSCLC patients, especially in the stage ⅢA.

Objective:To investigate the effects of rituximab on lymphocytes and immunoglobulin in the treatment of focal segmental glomerulosclerosis (FSGS) and minimal change disease (MCD).Methods:The subjects were FSGS and MCD patients admitted to Ruijin Hospital affiliated to Shanghai Jiaotong University on July 1, 2014 and July 1, 2019. All the enrolled patients were confirmed by clinical examination and renal biopsy, and received rituximab treatment (4 infusions of 375 mg/m 2 with the interval of 7-14 d). The levels of immunoglobulin IgA, IgG, IgM, and lymphocytes of CD19 +, CD20 +, CD3 +, CD3 +CD4 +, CD3 +CD8 + and natural killer cells (CD56 +CD16 +) were compared between baseline and the third month, the sixth month, the ninth month and the twelfth month after treatment. Results:Ninety-six patients with FSGS or MCD were enrolled in this study. The midian age was 28 years old (14-77 years old). The ratio of men to woman was 1.8∶1. There were 65 cases of MCD and 31 cases of FSGS. After rituximab treatment, the 24 h-proteinuria was significantly lower than that before treatment, and the serum albumin level was increased (both P<0.05). After rituximab treatment of 3 months, 6 months, 9 months and 12 months, CD19 + and CD20 + lymphocyte counts were significantly decreased (all P<0.01), and gradually recovered after 6 months. Compared with baseline, at 3, 6, 9, 12 months after rituximab treatment, the level of blood IgG was significantly increased ( P=0.004,<0.001,<0.001,<0.001, respectively), and the level of blood IgM was significantly decreased ( P<0.001, =0.008, =0.005,<0.001, respectively) but the median level still within the normal range (400-3 450 mg/L). The level of blood IgA was not significantly changed (all P<0.05). T lymphocytes (CD3 +, CD3 +CD4 + and CD3 +CD8 +) and natural killer cells (CD56 +CD16 +) showed no significant difference from baseline (all P>0.05). Conclusions:Rituximab can effectively eliminate CD19 + and CD20 + lymphocytes, and has little influence on peripheral blood lymphocyte count and immunoglobulin level except CD19 + and CD20 + lymphocytes. The standard administration of rituximab is safe for patients with FSGS and MCD.

Objective To compare the consistency between single-(I-GFR-SS) and dual-(I-GFR-DS) sample methods with three-sample method (I-GFR-TS) of iohexol plasma clearance in chronic kidney disease (CKD) patients for choosing the optimizing project of glomerular filtration rate (GFR) measurement.Methods The multiple-sample methods were performed in 174 patients with CKD admitted to the Department of Nephrology,Shanghai Ruijin Hospital from August 2017 to July 2018.Plasma concentrations of iohexol were measured three times at different time points after receiving 5 ml iohexol (300 g/L) intravenous injection,according to estimated GFR (eGFR) grouping.The first blood sample was collected at 2 hours,and the time for the last sample was delayed from 4 hours to 6 hours with reduction of eGFR.The synchronized Gates (99mTc-Gates-GFR) method was detected as control.With I-GFR-TS as the golden standard,the accuracies of I-GFR-DS,I-GFR-SS and 99mTc-Gates-GFR were compared.Results The median differences of I-GFR-DS,I-GFR-SS and 99mTc-Gates-GFR in overall patients were-0.15,-1.00,6.76 ml· min-1· (1.73 m2)-1 comparing with I-GFR-TS;P10(percentage of the GFRmeasurements that was within 10% of the standard method) were 95.4%,74.1%,28.7%,and P30 were 100%,93.7%,72.4% separately.In the patients with eGFR < 30 ml· min-1· (1.73 m2)-1,I-GFR-SS was more accurate when last point collecting extended to 6 h from 4 h [P10:43.5% vs 17.4%,P=0.055;P30:73.9% vs 43.5%,P<0.05].Conclusions The dual-sample plasma clearance of iohexol is recommended in clinical practice,and the single-sample method can be a secondary option because of its slightly poor accuracy but more convenient.Sample-collection protocol should be adjusted according to eGFR especially in moderate-to-severe CKD patients.The Gates method is not recommended.

Objective To analyze the clinicopathological characteristics of renal lesions in type 2 diabetic patients and to differentiate diabetic nephropathy (DN) from non-diabetic renal diseases (NDRD).Methods Type 2 diabetic patients who received renal biopsy in Ruijin Hospital from January 2011 to December 2015 were recruited in this study. Clinical history, laboratory results and pathological data were retrospectively collected. According to the pathological findings, the patients were divided into 3 groups: DN, NDRD, DN+NDRD. Logistic model was applied to explore the independent clinical predictive factors in differentiating DN from NDRD. Results A total of 207 type 2 diabetic patients received renal biopsy, accounting for 6.82% of all biopsy population. Fifty-one patients were diagnosed with DN, 142 with NDRD and 14 with both DN and NDRD. In NDRD, membranous nephropathy(MN) (34.5%) was the most common finding, followed by IgA nephropathy(19.7%).By contrast, NDRD patients manifested a shorter diabetic course, a higher baseline hemoglobin level, a lower baseline serum creatinine, a higher prevalence of hematuria, a lower prevalence of hypertension and diabetic retinopathy, a better control of blood glucose, better compliance of monitoring blood glucose and less family history of diabetes. In multivariate logistic model, diabetic family history(OR=4.68, P=0.04) and long history of diabetes(OR=1.01, P=0.02) were risk factors of DN. Conclusion There is a high prevalence of NDRD in diabetic patients with renal lesions. Family history of diabetes and duration of diabetes are independent predictors of DN.

Objective To identify the outcome of pregnancy and the alteration of renal function in women with nephrotic syndrome. Methods From 2003 to 2007, 59 pregnant women with nephrotic syndrome in our hospital were enrolled in the study. Their clinical data were retrospectively analyzed, including the time of kidney disease onset, 24-hour proteinuria, serum albumin, serum creatinine, blood uric acid, blood pressure, fetal survival, fetal mortality, rate of premature delivery, birth weight of the newborn, and proteinuria, renal function, blood pressure of the patients during their postpartum follow-up. Logistic regression analysis was used to identify the risk factors influencing the outcome of the patients and the newborns. Results The average gestational week was (20.35±9.40) weeks when proteinuria was detected in these pregnant women. The 24-hour proteinuria ranged from 3.5 to 15 g/24 h (median 5.1 g/24 h). The serum albumin was between 10 and 28 g/L (median 22.5 g/L). The serum creatinine was between 32 and 825 μmol/L (median 84 μmol/L) and the serum uric acid ranged from 196 to 793 μmol/L (median 385.5 μmol/L). Pregnancy-induced hypertension syndrome occurred in 75% of the patients, among whom 55.5% suffered from preeclampsia. Forty-three (72.9%) newborns survived , among whom 76.7% (33/43) were premature births and 62.8% (27/43) were low birth weight infants. 50% of the pregnant women still had nephrotic syndrome after delivery. 75% of 24 patients with pre-existing chronic glomerulonephritis had increased proteinuria during pregnancy. Among the 38 patients with renal insufficiency, 36.8% had poorer renal function after delivery. 23.7% of the patients progressed into end stage renal failure after delivery, 80% of whom had serum creatinine ≥ 265 μmol/L. 89% of the patients had persistent hypertension after childbirth. The Logistic regression analysis indicated hyperuricemia during pregnancy (P=0.018, OR=1.012) and the increase of serum creatinine (P=0.039, OR=1.005) were risk factors of renal failure in pregnant women after delivery. Hyperuricemia (P=0.012, OR=1.006)was the risk factor of fetal death. Conclusions Pregnancy with nephrotic syndrome leads to a low fetal survival. Hyperuricemia is the most important risk factor of the poor outcome of pregnant women and newborn.
