儿童慢性腹膜透析相关腹膜炎危险因素的病例对照研究

目的 分析终末期肾病（ESRD）患儿慢性腹膜透析（CPD）相关腹膜炎(简称腹膜炎)发生的危险因素,为儿童腹膜炎防治提供依据。方法 回顾性收集复旦大学附属儿科医院（我院）开展ESRD患儿CPD 以来的全部病历,依据连续随访记录,以是否出现CPD分为腹膜炎组和非腹膜炎组,分析两组人口学指标、CPD指标和透析充分性指标。并行多因素分析探讨发生腹膜炎的危险因素。结果 2001年至2014年在我院接受CPD治疗的109例ESRD患儿进入本文分析,男60例（55%）、女49例。开始腹膜透析的中位年龄9.9岁,中位透析病程13.4月。连续性非卧床腹膜透析（CAPD）15例,自动腹膜透析（APD）94例（86.2％）。43例（39.4%）仍接受CPD治疗,50例（45.9%）成功行肾移植,7例（6.4%）转行血液透析治疗,6例（5.5%）死亡,3例（2.8%）失访。1、2、3和5年的生存率分别为97.1%、93.3%、90.1%和90.1%。33例发生57例次腹膜炎,平均腹膜炎发生率为1次/35.1病人月。单因素分析显示,开始透析时身高SDS（P=0.01）、透析病程（P<0.001）和白蛋白水平（P=0.01）腹膜炎组和非腹膜炎组差异有统计学意义。多因素Logistic回归分析显示,开始透析时身高SDS<-2.0（OR=12.746,95％CI：2.436~66.675,P=0.003）和透析病程>1年（OR=8.162,95%CI：2.514~26.500,P<0.001）是腹膜炎发生的独立危险因素。结论 开始透析时身高SDS<-2.0和透析病程>1年是儿童CPD相关腹膜炎发生的独立危险因素。     

腹膜透析在9例慢性肾功能衰竭患儿中的应用

目的分析和评价腹膜透析在终末期肾衰竭(ESRD)患儿中的应用情况。方法对复旦大学儿科医院肾脏科2001-11—2005-04收治的9例(男7例,女2例)ESRD患儿腹膜透析前后尿毒症症状改善情况和营养、生长发育状况进行回顾分析。结果腹膜透析模式：持续性非卧床腹膜透析(CAPD)3例,持续性循环腹膜透析(CCPD)5例,夜间间歇性腹膜透析(NIPD)1例,透析时平均年龄(11.6±3.0)岁,平均腹透(9.8±7.1)个月(2~36个月)。透析后,尿毒症症状均有改善,胃肠道症状消失,血尿素氮由透析前(31.4±7.4)mmol/L下降至透析后(19.6±3.4)mmol/L(P<0.01);平均血红蛋白及红细胞压积比由透析前的(77.1±19.9)g/L和(22±6)%上升至(98.4±40.2)g/L和(34±4)%;平均血压由透析前18.9/11.7kPa下降至透析后14.6/9.6kPa(P<0.01);透析前血钙(2.0±0.2)mmol/L,血磷(2.2±0.5)mmol/L,甲状旁腺素(PTH)(602.7±332.2)pg/mL,透析后血钙2.5±0.2mmol/L,血磷(1.59±0.3)mmol/L,PTH(258.6±273.2)pg/mL,与透析前比较差异均有显著性(P<0.05),钙磷代谢紊乱纠正,高PTH改善。透析后血白蛋白(41.0±3.2)g/L、Pre-A>400mg/L,Tf>2g/L,身高、体重增加,身高平均增长(0.67±0.59)cm/月。腹膜炎发生率为1次/11.1病人月。结论长期腹膜透析可以很好地改善ESRD患儿的尿毒症症状,纠正贫血、高血压、钙磷代谢紊乱,改善营养和生长发育状况,是ESRD患儿进行肾替代治疗的有效手段。但腹膜透析也有一定的并发症,应引起重视。     

腹膜透析充分性对腹膜透析儿童营养状况的影响

目的前瞻性观察慢性腹膜透析(腹透)儿童的营养状况,探讨透析充分性对腹透儿童营养状况的影响。方法选择腹透时间超过3个月儿童,每3个月留取腹透液、尿液,抽血测BUN、Scr、清蛋白(Alb)、前清蛋白(PA)、转铁蛋白(Tf),计算尿素清除指数(Kt/V)、肌酐清除率(Ccr)、残余肾功能(RRF)、蛋白分解率(PCR),分析透析充分性与营养状况的关系。结果腹膜透析儿童10例(男6例,女4例)。平均年龄11.90岁(8.3～16.1岁);腹膜透析4～36个月,平均12.50个月。10例共进行32次检测,Scr为(830.31±156.48)μmol/L,BUN为(21.44±7.99)mmol/L,血浆Alb为(42.71±5.21)g/L,PA(419.68±118.0)mg/L,Tf(1.94±0.58)g/L,每周总Kt/V2.15±0.29,残余肾Kt/V0.57±0.45,每周总Ccr(49.13±15.25)L/1.73m2,残余肾Ccr(19.48±13.11)L/1.73m2,RRF(1.70±1.56)mL/min,PCR(1.17±0.18)g/(kg.d)。PCR与总Kt/V和总Ccr呈正相关(r=0.775,0.503Pa<0.01),与残肾Kt/V、残肾Ccr呈正相关(r=0.532,0.393Pa<0.05)。总Kt/V分别与Alb和PA呈正相关(r=0.496,0.541Pa<0.01),与Tf无关(r=0.226P>0.05)。RRF与总Ccr呈正相关(r=0.389P<0.05)。结论提高透析充分性有利于改善腹透儿童营养状况,制定合适透析处方以确保充分透析是预防腹透儿童营养不良的根本措施。     

慢性肾脏病及透析患儿的疫苗接种

慢性肾脏病患儿大多存在免疫紊乱及免疫功能缺陷.各种病原菌的感染率明显增高,尤其容易感染肺炎链球菌、HBV及流感病毒.在全球范围内,肺炎链球菌是细菌性肺炎和中耳炎的最常见病原,是细菌性脑膜炎的主要病原菌.血液透析的患儿更是HBV易感染的高危人群.流感是具有高度传染性及极其广泛的传播性疾病.美国免疫实践指南咨询委员会(ACIP)及改善全球肾脏病预后(KDIGO)特别推荐慢性肾脏病及慢性透析的患者接种的3种疫苗是HBV疫苗、灭活流感病毒疫苗及肺炎链球菌疫苗.接种疫苗是特异性的预防措施,可对慢性肾脏病及透析患者提供有效的预防保护.     

持续性腹膜透析儿童腹膜平衡试验及结果分析

目的通过腹膜平衡试验（PET）探讨我国慢性腹膜透析（PD）儿童腹膜转运特性特点。方法对6例持续性非卧床腹膜透析（CAPD）患儿（2—14岁）行10次儿童标准PET,参照Twardowski和儿科腹膜透析联盟（PPDSC）标准评价腹膜溶质转运类型。结果本组患儿首次PET于PD开始后平均（38．74±15．6）d进行。4h肌酐清除率（4h-D／P）和4h葡萄糖吸收率（4h-D／D0）分别为（0．85±0．24）、（0．34±0．19）。依Twardowski和PPDSC腹膜转运类型评价标准,本组腹膜溶质转运类型分别为高转运型6例（6／10）、高平均转运型1例（1／10）、低平均转运型3例（3／10）,无一例低转运型;两种标准分型的总符合率100％。本组腹膜葡萄糖转运类型分别为高转运型3例（3／10）、高平均转运型4例（4／10）、低平均转运型1例（1／10）,低转运型2例（2／10）;两种标准分型的总符合率90％。连续PET显示转运类型变化不一,腹膜炎后4h-D／P升高。结论本组CAPD儿童腹膜溶质和葡萄糖转运类型均以高转运和高平均转运为主（7／10）,呈偏态分布,提示儿童腹透溶质清除充分,但水超滤能力不足;标准儿童PET及其评价标准完全符合Twardowski标准PET要求。腹膜炎后溶质转运能力提高。

胃炎患儿幽门螺杆菌感染危险因素的病例-病例对照研究

目的了解和探讨浙江省绍兴地区目前儿童幽门螺杆菌(H·pylori)感染率及临床状况,评价感染相关危险因素。方法2003—2005在浙江绍兴市人民医院用olympus GIF P30纤维胃镜对301例具有上消化道症状持续1个月以上的患儿进行胃镜检查,同时对患儿的年龄、性别、生活地区,环境因素(居住拥挤程度,卫生设施)、社会地位(母亲职业),经济条件(家庭收入),年幼时是否母乳喂养,患儿母亲受教育程度,密切接触患儿的监护人是否既往有胃部疾患史,患儿婴幼儿期是否有进食父母嚼后食物等因素进行调查分析。结果该地区儿童H·pylori的感染率为33·6%;消化性溃疡H·pylori的感染率为65·4%;年幼时进食父母嚼后食物会增加小儿H·pylori感染的风险,随母亲文化程度增高H·pylori感染风险降低;该地区儿童H·pylori感染与患儿年幼时是否母乳喂养,监护人是否有胃病史,母亲职业,家庭经济收入,生活地区等因素无统计意义上的关联。结论儿童H·pylori的感染率随年龄增大而增高;H·pylori感染与母亲文化程度,年幼时是否进食父母嚼后食物有关;儿童H·pylori感染易增加患溃疡的风险。

Efficacy of Once Weekly Erythropoietin Therapy in Children on Continuous Ambulatory Peritoneal Dialysis

The efficacy of recombinant human erythropoietin (rHuEPO) on 10 anemic children undergoing continuous ambulatory peritoneal dialysis (CAPD) was evaluated. A mean dose of 93 U/kg of rHuEPO was given once a week for 24 weeks, either intravenously to 5 children or subcutaneously to the other 5. Anemia improved in all children by this therapy. The mean hemoglobin and hematocrit levels increased gradually but significantly from 6.9 g/dl and 20.2% to 9.4 g/dl and 30.1%, respectively, at the end of the study. Elevation of blood pressure or other side effects were not noted in any patient. The present study indicates that the once-a-week injection of rHuEPO by the intravenous or subcutaneous route is effective in children undergoing CAPD.     

High-volume peritoneal dialysis rescues a severe influenza A child with multiple organ dysfunction syndrome北大核心CSCD

A 3-year-old girl was hospitalized for cough and asthma for 2 days, and fever and anuria for 1 day in Department of Pediatrics, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology in January 2019.Retrospective analysis was used.She developed end-stage renal disease and received peritoneal dialysis 6 months ago.After admission, she was diagnosed as acute-on-chronic renal failure, respiratory failure, heart failure, severe influenza A (H1N1). The patient was rapidly recovered by the management of high-volume peritoneal dialysis, mechanical ventilation, and medications of Peramivir and Methylprednisolone.Through literature review, case report or cohort study about the treatment of acute kidney disease by high-volume peritoneal dialysis has not been previously reported.This case report suggested that high-volume peritoneal dialysis is able to effectively remove solutes and control volume without causing severe hypoproteinemia and hyperglycemia, which may become an effective renal replacement therapy for children with multi-organ dysfunction syndrome. © 2022 Chin J Pathol, June.

Advances in renal replacement therapy as a bridge to renal transplantation

While renal transplantation remains the most prevalent treatment for children with end-stage renal disease, the majority of children incident to ESRD receive dialytic therapy prior to receiving a renal allograft and 25% of children are still receiving dialytic therapy 36 months after achieving ESRD. The current review discusses the most recent advancements in both hemodialysis and PD therapies to provide optimal care for children as a bridge until renal transplantation. Areas covered include dialysis dose assessment, target dry weight assessment, vascular access and advancements in PD technology.     

Changning pattern of chronic renal failure and renal replacement therapy in children and adolescents: a 20-year single centre study

We analysed the demographic data, clinical course and survival on different forms of renal replacement therapy (RRT) of 374 children and adolescents with chronic renal failure observed between 1969 and 1988 and compared the findings for the four subsequent 5-year periods. The proportion of children below 5 years of age rose from 21% to 47%. With time the incidence of glomerulonephritis increased and that of pyelonephritis decreased. As RRT became more common, more very young children and more adolescents were admitted to the study. In the last 5 years continuous ambulatory peritoncal dialysis (CAPD) and haemodialysis (HD) were performed to the same extent as the initial form of RRT. The time a subject had to wait for a first transplant decreased from 36 to 21 months. Between 1969 and 1988 overall survival on any form of RRT increased to 77% after 10 years of therapy. In the last observation period 2-year patient survival was 100% both on HD and CAPD. First cadaver graft survival after 4 years improved from 25% in 1969–1973 to 69% in 1984–1988.
