Objective:To investigate the efficacy and safety of Rituximab (RTX) in the treatment of children with frequently relapsing/steroid-dependent nephrotic syndrome (FRNS/SDNS) and to analyze the factors influencing the efficacy.Methods:Case series study.The clinical data of children with FRNS/SDNS who received B-cell-guided RTX (single dose: 375 mg/m 2, maximum dose: 500 mg, one additional dose when peripheral blood CD19 + B lymphocytes ≥0.01) in the First Affiliated Hospital of Zhengzhou University from September 2019 to March 2022 were retrospectively collected.The frequency of relapse and cumulative dose of glucocorticoids before and after RTX treatment were compared.The Kaplan-Meier method was used to analyze relapse-free survival rate and FRNS/SDNS-free survival rate after RTX treatment.The influencing factors of relapse were analyzed using the Cox proportional hazards regression model. Results:Totally 47 children were enrolled, including 35 males and 12 females; the age of first application of RTX was 10.2 (6.9, 13.0) years; 33 children had used one type of immunosuppressant before, and 14 children had used two or more types of immunosuppressant before; the dose of RTX treatment was 3.0 (2.0, 3.0). The frequency of relapse[0(0, 0.55) times/year vs.1.62 (1.09, 2.40) times/year] and cumulative dose of glucocorticoids[0.12 (0.05, 0.21) mg/(kg·d) vs.0.40 (0.20, 0.56) mg/(kg·d)] after RTX treatment significantly decreased compared with previous immunosuppressive treatment ( Z=-5.56, -5.54, all P<0.001). The relapse-free survival rates at 6, 12, 18 and 24 months after treatment were 80.9%, 72.3%, 68.1% and 68.1%, respectively, and the FRNS/SDNS-free survival rates were 93.6%, 89.4%, 89.4% and 89.4%, respectively.Univariate Cox regression analysis showed that the high frequency of relapse during previous immunosuppressive therapy was a risk factor for relapse after RTX treatment ( P<0.05). Of the 14 children who relapsed, 6 occurred in children whose CD19 + B lymphocytes<0.01, and the frequency of relapse after RTX treatment was significantly higher than those whose CD19 + B lymphocytes≥0.01 ( Z=-2.84, P=0.005). No severe adverse reactions occurred during RTX treatment and follow-up. Conclusions:The B-cell-guided RTX is effective and safe in the treatment of FRNS/SDNS in children.The high frequency of relapse during previous immunosuppressive therapy is a risk factor for relapse after RTX treatment, and relapse in the state of B lymphocyte depletion predicts poor outcomes of RTX treatment.

Objective:To analyze the clinicopathological features and prognosis of idiopathic membranous nephropathy (IMN) in children, and to investigate the factors influencing their prognosis.Methods:The clinical and pathological data of 128 children with IMN hospitalized in the First Affiliated Hospital of Zhengzhou University from January 2012 to December 2019 were retrospectively analyzed.They were divided into 2 groups according to the pathological manifestations: group A[typical membranous nephropathy(MN) group] and group B (atypical MN group), and the clinicopathological characteristics of the 2 groups were compared.Different treatment regimens and their efficacy were summarized, and the prognosis and its influencing factors were analyzed.The primary endpoint event at follow-up was the occurrence of end stage renal disease (ESRD), and the secondary endpoint event was the occurrence of renal insufficiency.Children with IMN were further divided into endpoint event group and non-endpoint event group according to the presence or absence of endpoint events at the last follow-up.Survival analysis was performed using the Kaplan-Meier survival curve method.The Cox proportional risk model method was used to analyze the factors influencing the prognosis of poor kidney outcomes in children with IMN. Results:(1)A total of 128 children were included, with the male-to-female ratio of 1.13∶1.00.The median age of onset and peak age of onset were 13.0 (10.3, 15.0) years, and 12-16 years (68.8%), respectively.Massive proteinuria was detected in 119 cases (93.0%), including 103 cases (80.5%) with massive proteinuria and hematuria, 4 cases(3.1%) with simple hematuria, and 5 cases (3.9%) with non-renal proteinuria.There were 29 cases (22.7%) in group A and 99 cases (77.3%) in group B. (2)Blood triacylglycerol level was significantly higher in group B than that of group A[2.1 (1.5, 3.0) mmol/L vs.1.7(1.1, 2.5) mmol/L], while high-density lipoprotein[1.5(1.1, 1.8) mmol/L vs.1.8(1.4, 2.1) mmol/L], serum albumin[22.0(17.0, 27.3) g/L vs.25.5 (21.0, 32.5) g/L] and complement C3[(1.1±0.2) g/L vs.(1.2±0.2) g/L] were significantly lower in group B than those of group A (all P<0.05). (3)Complete clinical data during hospitalization and follow-up data were obtained from 91 children with IMN, with a median follow-up time of 87.0 (49.0, 104.5) months.Among them, 5 cases (5.5%) progressed to ESRD, involving 3 cases received renal transplantation, and 9 cases (9.9%) had secondary endpoints.Cumulative renal survival rate for ESRD at 5 and 10 years were 96.2% and 92.9%, respectively, which, for the secondary endpoints at 5 and 10 years were 95.2% and 84.8%, respectively.(4)Kaplan-Meier survival analysis showed no significant difference in the cumulative renal survival between group A and group B ( P>0.05). Multifactorial Cox regression analysis showed that tubular atrophy/interstitial fibrosis was an independent risk factor for renal insufficiency in children with IMN ( HR=0.102, 95% CI: 0.011-0.940, P<0.05). Conclusions:Massive proteinuria combined with hematuria is the major clinical manifestation of IMN in children, and atypical MN is the major pathological manifestation.Tubular atrophy/interstitial fibrosis is an independent risk factor for renal insufficiency in children with IMN.

Objective:To summarize the clinical features and gene phenotype of children with spondyloenchondrodysplasia with immune dysregulation (SPENCDI) caused by ACP5 gene mutation. Methods:The medical data and genetic phenotype of a child diagnosed with SPENCDI in the Department of Pediatrics, the First Affiliated Hospital of Zhengzhou University in February 23, 2017 were analyzed retrospectively.Besides, " spondyloenchondrodysplasia" were taken as the search terms to perform the retrieval in CNKI, Wanfang Data, and PubMed, in an attempt to conduct the literature review.χ 2 test was used to compare the factors among children with different mutations. Results:The 4.5-year-old girl was admitted to hospital for complaint of " fever and chilblain-like rash" when she was 2 years old.She was diagnosed with systemic lupus erythematosus (SLE) concomitant with lupus nephritis.Methylprednisolone combined with cyclophosphamide, mycophenolate mofetil was used for the treatment.However, she experienced multiple infections, thrombocytopenia, limp, and growth retardation during the treatment.Genetic detection identified ACP5 gene compound hybrid mutation: c.779C>A and c. 770T>C.She was diagnosed with SPENCDI, and was subjected to follow-up.A total of 78 SPENCDI patients were retrieved from the databases, with various clinical manifestations of SPENCDI, commonly with skeletal involvement and immune phenotypes; 73.08% of the cases were positive for antinuclear antibodies, 57.69% of cases were positive for anti-double stranded-DNA antibodies and 34.62% of cases had neurological symptoms.In 58 cases, ACP5 gene mutations were detected, including 44 homozygous mutations and 14 compound heterozygous mutations.Patients with ACP5 gene homozygous mutation had a higher probability of consanguineous marriage in parents [56.82% (25/44 cases) vs.14.29% (2/14 cases)]; patients with ACP5 gene heterozygous mutation were more likely to develop SLE [64.29% (9/14 cases) vs.34.09% (15/44 cases)]( χ2=7.722, 3.992; all P<0.05). Conclusions:The majority of the ACP5 gene mutations are homozygous mutations in patients with SPENCDI, and heterozygous mutations are rare.The clinical manifestations of SPENCDI are various and complex, it is prone to develop autoimmune diseases, and there was no clear correlation between clinical features and gene phenotype in SPENCDI patients.

Objective To investigate the changes in serum cortisol and adrenocorticotrophic hormone(ACTH) levels in children with steroid-sensitive nephritic syndrome (SSNS) and the clinical significance of intervention.Methods According to whether a child with SSNS would relapse,48 children with SSNS were divided into non-recurrence group(n =19) and recurrence group(n =29),at the same time 14 age-matched healthy children were enrolled as the healthy control group.Serum cortisol and ACTH were measured in patients with SSNS by using electrochemiluminesence methods.In recurrence group,methylpredisolone or methylprednisolone combined with ACTH injection therapy was used on 15 patients with their serum cortisol and ACTH below normal.Results Before standard glucocorticoid treatment,the serum levels of cortisol and ACTH had no difference among 3 groups (all P ＞ 0.05).By the end of remission phase,the serum levels of cortisol and ACTH in recurrence group were statistically lower than those of the non-recurrence group[(113.03 ± 80.02) μg/L vs (251.54 ± 185.05) μg/L,t =-2.925,P ＜ 0.05 ; (12.81 ± 10.14) ng/L vs (23.53 ± 12.05) ng/L,t =-0.885,P ＜ 0.05].Eight to 12 weeks after being adjusted,the serum level of cortisol and the average monthly time of recurrent were both significantly improved in 15 abnormal children in recurrence group [(168.90 ± 133.43) μg/L vs (73.62 ± 58.04) μg/L,t =3.016,P ＜ 0.05 ; (0.09 ± 0.08) times vs (0.35 ± 0.11) times,t =-7.560,P ＜0.05],but as to the serum level of ACTH,there was no significant difference in abnormal children in recurrence group [(14.05 ± 10.99) ng/L vs (8.72 ± 4.11) ng/L,t =1.991,P ＞ 0.05].Conclusions The concentrations of serum cortisol and ACTH can reveal the risk of recurrence for children with SSNS to some extent,and effective intervention can reduce the recurrence rate and shorten the course of disease.
摘要
Objective To evaluate the efficacy and safety of intrapleural fibrinolytic agents in the treatment of childhood empyema.Methods The data from China National Knowledge Infrastructure (CNKI),Chinese BioMedical (CBM),PubMed,VIP Database and Cochrane library were reviewed.Randomized control trials by using intrapleural fibrinolytic agents to treat childhood empyema were included.Two reviewers independently extracted the data from the eligible studies and evaluated the quality of the included studies.Meta-analysis was performed for the results of homogeneous studies using RevMan 5.2 software,while others analyzed descriptively.Results Five randomized control trials involving 248 children with empyema were included.Meta-analysis was not made in all of the indexes because of apparent heterogeneity and limited data.Two trials were compared which involved 98 patients receiving fibrinolytic agents or 9 g/L saline.The results suggested that fibrinolytic agents shortened the length of hospital stay and reduced complication(all P ＜ 0.05),but no significant differences were found between the 2 groups in the effective rate,duration of fever and pleural effusion amount(OR =3.61,95％ CI 0.84-15.49,P ＞ 0.05).Three trials involving 150 patients compared fibrinolytic agents and video-assisted thoracoscopic surgery (VATS).The data suggested that no significant differences were found between 2 groups in the effective rate (OR =0.70,95 ％ CI 0.30-0.61,P ＞ 0.05),but fibrinolytic agents cost less (P ＜ 0.05).The adverse drug reactions to intrapleural fibrinolytic agents were mild to moderate,and well tolerated.Conclusions The findings suggest that intrapleural fibrinolytic agents in the treatment of childhood empyema is safe and effective,especially in encapsulated effusion.Compared to 9 g/L saline,it can shorten the length of hospital stay and reduce complication.Compared with VATS,the curative effect is similar,while intrapleural fibrinolytic agents are economic.

Objective To investigate the correlation between food intolerance and Henoch-Sch(o)nlein purpura (HSP) in children and the efficacy of food forbidden or alternative therapy. Methods The levels of IgG against several common food in serum obtained from 40 children with HSP were measured by ELISA. The efficacy of food forbidden or alternative food therapy was assessed after 3 months. Results Total positive rate of serum food-intolerant IgG antibodies in HSP children was 92.5%. Among these 14 intolerant foods, the positive percentage of egg was the highest (33.8%), followed by tomato (14.9%), milk (13.5%) and morrhua (12.2%). Significant differences of the sort and degree of food intolerance existed among different age groups (t=2.257, P=0.045), but not between boys and girls (t=1.053, P=0.315), city and countryside (t= 1.388, P=0.193). There was no linear correlation between total food intolerance and serum IgG level (t=0.793, P=0.445). Food intolerance had no direct relation to immune complex deposition in kidneys of HSP nephritis (r =-0.262, P =0.387). The efficacy of adjusting diet was 95% . Conclusions HSP is closely related to food intolerance. Egg is the most common intolerant food. Food forbidden or alternative therapy shows acceptable efficacy in the treatment of most Henoch-Sch(o)nlein purpura children.
