摘要
目的探讨应用不同剂量连续性肾脏替代治疗(CRRT)对重症肺炎合并急性肾损伤(AKI)患者的效果。方法回顾性分析2009年2月至2012年3月贵州省人民医院收治并采用连续性静一静脉血液透析滤过(CVVHDF)治疗的28例重症肺炎合并急性肾损伤患者的临床资料。其中大剂量(70ml·kg-1·h-1)组9例,中剂量(45ml·kg-1·h-1)组8例,小剂量(25ml·kg-1·h-1)组11例。分析3组患者治疗前后病情、血气分析、外周血白细胞计数、中性粒细胞百分比及肾功能变化,检测血清C反应蛋白(CRP)、肿瘤坏死因子(TNF-α)、白细胞介素(IL)-6及IL.8变化。结果治疗前大、中、小剂量组外周血白细胞计数分别为(14.2±8.6)、(13.3±6.3)、(14.3±5.7)X109/L。中性粒细胞百分比分别为(90.9±5.1)%、(89.9±4.2)%、(91.3±3.1)%,CRP分别为(122±41)、(117±22)、(118±32)mg/L,TNF-α分别为(307±56)、(297±45)、(301±52)pg/L,IL-6和IL.8分别为(214±55)、(210±47)、(216±40)pg/L和(608±131)、(591±110)、(600±140)pg/L,血尿素氮(BUN)和肌酐(cr)分别为(68.3±18.2)、(71.5±21.1)、(69.3±19.5)mmol/L和(811±133)、(798±145)、(806±182)μmol/L,24h尿量分别(320±80)、(330±69)、(350±70)ml;三组各指标差异均无统计学意义(均P〉0.05)。治疗后大、中、小剂量组外周血白细胞计数分别为(11.0±3.2)X10’/L、(11.1±5.3)×10’/L、(8.5±2.7)X10’/L,中性粒细胞百分比分别为(83.3±3.1)%、(84.9+4.3)%、(75.3±2.6)%,CRP分别为(89±10)、(90±14)、(107±13)mg/L,TNF-α.分别为(99-I-39)、(103±28)、(123±35)pg/L,大、中剂量组与小剂量组差异均有统计学意义(均P〈0.05);IL-6和IL.8分别为(54±22)、(69±20)、(81±24)pg/L和(104±50)、(138±63)、(167±71)pg/L,大、中剂量组与小剂量组之间及大剂量组与中剂量组之间差异均有统计学意义(均P〈0.05);BUN和Cr分别为(7.1±2.5)、(8.5±3.8)、(8.9±12.9)mmol/L和(86±21)、(118±28)、(128±35)ixmol/L,24h尿量分别为(1550±92)、(1280±102)、(1202±89)ml,大剂量组与中、小剂量组差异均有统计学意义(均P〈0.05)。大、中剂量组病情改善较小剂量组明显,6个月生存率(66.7%、62.5%)均显著高于小剂量组(45.5%)(均P〈0.05),但大、中剂量组间差异无统计学意义(P〉0.05)。结论大剂量CRRT治疗更有利于清除炎症介质,提高重症肺炎合并急性肾损伤患者的生存率。
Objective To explore the efficacy of different doses of continuous renal replacement therapy (CRRT) in the treatment of severe pneumonia with acute kidney injury. Methods Twenty-eight patients with severe pneumonia and acute kidney injury were recruited from our hospital between February 2009 and March 2012. They divided into 3 groups : group A receiving a large dose of continuous veno-venous hemodiafilteration (CVVHDF) (70 ml ± kg-1 ± h-±, n = 9), group B a moderate dose of CVVHDF (45 ml.kg-± -h-l, n=8) and groupC a low dose of CVVHDF (25 ml" kg-X ± h-l, n=ll). Before and after treatment, the changes of patient conditions, renal function and blood gas analysis were recorded. Such biomarkers as C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-ot), interleukin-6 ( IL-6), interleukin-8 ( IL-8 ), white blood cell (WBC) and neutrophile granulocyte (N) were determined. Results Compared with group C, the levels of leucocyte ((11.0±3.2) mg/L, (11.1 ±5.3) xlOg/L vs (8. 5 ± 2.7 ) x 109/L), CRP ( ( 89 ± 10), (90 ± 14) vs ( 107 ± 13 ) mg/L), TNF-ct ( (99 ± 39), (103 ±28) vs (123 ±35) pg/L), IL-6 ((54 ±22), (69 ±20) vs (81 ±24) pg/L) and IL-8 ((104 ± 50), (138 ±63) vs (167 ±71) pg/L) decreased significantly in groups A and B after treatment (all P 〈 O. 05 ). There were no differences in the levels of CRP, IL-6, IL-8 or TNF-ot levels between groups B and C ( all P 〉 O. 05 ). The recovery of kidney function was much more rapid in group A than in groups B and C. Conclusion The large dose of CRRT may be more effective in the clearance of inflammatory mediators and improved survival of severe pneumonia with acute kidnev iniurv than moderate and low doses
