摘  要:目的分析激素耐药型肾病综合征(SRNS)的病理、重复肾活检情况、治疗、预后及局灶节段性肾小球硬化(FSGS)的高危因素。方法回顾性分析2006年9月1日至2016年8月31日在中山大学附属第一医院小儿肾病中心进行。肾活检的172例患儿的SRNS病历资料。结果172例患儿主要病理类型:FSGS72例(41.9%)、微小病变(MCD)52例(30.2%)、系膜增生性。肾小球肾炎(MsPGN)31例(18.0%)。11例进行重复。肾活检(6.4%),6例MCD患儿中5例转变为FSGS;3例FSGS患儿重复肾活检病理仍为FSGS,但亚型发生改变;2例MsPGN患儿重复肾活检均为FSGS。与非FSGS比较,FSGS的发病年龄较小[3.0(1.7,6.0)岁比5.8(3.4,8.9)岁],血浆清蛋白水平低[18.0(14.O,22.9)g/L比20.0(15.1,29.1)g/L],24h尿蛋白定量水平高[136.0(76.0,200.0)mg/(kg·d)比93.0(55.3,150.0)mg(kg·d)],差异均有统计学意义(均P〈0.05)。LogiStic回归分析显示年龄越小(P=0.007)、24h尿蛋白定量越高(P=0.028),病理表现为FSGS的风险越大;受试者工作特征曲线分析显示,24h尿蛋白定量最佳临界值为131mg(k·d)。MCD患儿环磷酰胺(CTX)治疗有效率(10/12例)高于FSGS(1/5例)和MsPGN(1/2例)患儿,差异均有统计学意义(均P〈O.05)。FSGS、MCD、MsPGN患儿他克莫司(TAc)、环孢素(cSA)治疗的疗效差异无统计学意义(均P〉0.05)。62例FSGS患儿中有效25例(56.4%),44例MCD患儿中有效37例(84.1%),25例MsPGN患儿中有效15例(60.O%),不同病理类型预后的差异有统计学意义(P〈0.05)。结论SRNS患儿最常见的病理类型为FSGS、MCD、MsPGN,但病理类型可相互转换。年龄越小、24h尿蛋白定量越高,病理类型表现为FSGS的风险越大。当24h尿蛋白定量〉131mg(kg·d)时应警惕病理类�Objective To analyze the pathologic constitution, repeated renal biopsy, treatment, prognosis and focal segmental glomeruloselerosis (FSGS) risk factors of children with steroid - resistant nephrotic syndrome (SRNS). Methods A retrospective analysis was made of 172 SRNS cases of renal biopsy in the Pediatric Nephrology Center, the First Affiliated Hospital of Sun Yat - Sen University from September 1,2006 to August 31,2016. Results The main pathological types of 172 children with SRNS were FSGS in 72 eases (41.9%) , minimal change disease (MCD) in 52 cases (30.2%) ,and mesangial proliferative glomerulonephritis (MsPGN) in 31 cases ( 18.0% ). There were 11 cases (6.4%) with repeated renal biopsy,5 cases of 6 children with MCD changed to FSGS;3 cases of FSGS whose repeated renal biopsy were still FSGS,but the subtype had changed;2 cases of MsPGN changed to FSGS in repeated renal biopsy. Compared to non- FSGS,the age of onset of FSGS was smaller [3.0(1.7,6.0) years old vs. 5.8 (3.4,8.9) years old ], the plasma albumin of FSGS was lower [ 18.0 (14.0,22.9) g/L vs. 20.0 (15. 1,29. 1 ) g/L] ,the 24 hours urine protein level was higher [ 136.0 (76. O, 200.0) rag/( kg · d) vs. 93.0 (55.3,150.0) rag/( kg · d) ] , and the differences were all significant ( all P 〈 0.05 ). Logistic regression analysis showed that the smaller the age( P = 0. 007 ) , the higher the 24 -hour urine protein( P = 0. 028 ) , the greater the risk of FSGS. The receiver operating characteristic (ROC) curve analysis showed that the optimal critical value of 24 hour urine protein was 131 rag/( kg · d). The effective rate of Cyeloposphamide (CTX) treatment in MCD children (10/12 cases) was higher than that of FSGS ( 1/5 cases) and MsPGN ( 1/2 cases) ,and the differences were statistically significant (all P 〈0. 05). There was no significa·t difference in the curative effect of Tacrolimus (TAC) and Ciclosporin A (CsA) in children with FS
