Methods Two patients who were admitted into our hospital for acute renal failure caused by over-dose ciliatenerve knotweed root from March to September in 2007 were included in this study. We analyzed the clinical and pathological manifestations of their kidneys. Results Over-dose ciliatenerve knotweed root could induce acute renal failure, even threaten life. The pathology of kidney is characterized by severe tubular injury,rather than glomerulus damage, without cell infiltration. Conclusions Ciliatenerve knotweed root is one of the frequently-used traditional Chinese medicines in our country, which can easily result in aristolochinc acid nephropathy. We should recognize the importance of this disease and avoid using nephrotoxic drugs.
目的 探讨连续肾脏替代疗法(CRRT)对ICU急性肾功能衰竭(ARF)患者的血浆细胞因子、肾功能指标及其预后的影响。方法 选取我科2002年6月至2003年11月符合ARF的ICU患者38例,其中治疗组20例采用CRRT治疗,对照组18例采用肾脏非替代治疗(保守治疗)。两组患者于治疗前、后分别抽取静脉血标本作血浆细胞因子和肾功能指标的检测,并统计两组患者的临床死亡病例数。 结果 与对照组比较,治疗组的血浆肿瘤坏死因子、白细胞介素-6、白细胞介素-8及血肌酐和血尿素氮水平有显著改善(P<0.05),而临床死亡率改变不明显(Pgt;0.05)。结论 CRRT能有效清除ICU的ARF患者的炎性细胞因子,改善肾功能指标,但其最终预后仍然很差。对于ICU的ARF患者,应该强调预防的重要性。
Experienc of nurtitional treatment to 7 patients with acute renal failure (ARF) and nitrogemia after biliarty (tract) surgery is reported in this article. Nittrogen source inn all cases was obtained from "Renal Amine" and "7% Vamin" etc,which are composed of 8 essential amino acids (EAA), and the nergery sources are mainly supplyed by Intralipid (20 or 10%) and suitable amount of glucose. The nutritional admicture of "all in one" were employed as parenteral nutrition (PN). Satisfactary curative effecs in these patients were obtained. The suthors consider that (a) the nutritional treatment of different casuses of ARF should be providing enough energy and more EAA requirments than in normal need to synthesizw non-essential amino acide (NEAA) and protein from excessive blood urea nitrogen (BUN) for redcuing pritein breakdown and nitrogemia, and (b) 20% Intralipid is an effective low-volume, highly calories nutritional agent specially in ARF patients with restiction of waterr.
Abstract: Objective To investigate the application value of the Clinical Score developed by Cleveland University in predicting the occurrence ratio of acute renal failure in Chinese patients after cardiac surgery. Methods A total of 456 adult patients , 230 males and 226 females , with cardiac surgery during August 2008 to July 2009 were included in our study. Their age ranged from 18 to 88 years with an average age of 56.7 years. Before the surgery, Clinical Score was used to predict acute renal failure after cardiac surgery. Based on the score of ≤5, 610, or ≥11, the patients were divided into group Ⅰ (n=401), group Ⅱ (n=42) and group Ⅲ (n=13). The occurrence rate of acute kidney injury (AKI), continuous renal replacement therapy in hospital, multiple organ failure, mortality and other clinical indexes were compared among the 3 groups. Results Occurrence ratio of AKI of group Ⅰ, Ⅱ, Ⅲ was respectively 2.74%, 28.57% and 76.92% (χ2=73.004, P=0.000). Continuous renal replacement therapy rate was respectively 0.50%, 9.52%, and 38.46% (χ2=36.939, P=0.000). Multiple organ failure rate was respectively 0.50%, 4.76%, and 23.08% (χ2=19.694, P=0.000). Mortality rate was respectively 0.25%, 2.38%, and 15.38% (χ2=14.061, P=0.001). There were significant differences among the three groups. Conclusion The Clinical Score to Predict Acute Renal Failure developed by Cleveland University can effectively predict the occurrence rate of acute renal failure in the Chinese patients after cardiac surgery before the operation. Therefore, corresponding preventive methods can be taken for highrisk patients.
Acute renal failure(ARF) is a serious complication after cardiac surgery. It is an important influential factor of increasing mortality, extending mechanical ventilation time and intensive care unit time, resulting in cognition functional impairment and respiratory function failure et al, and increasing cost of hospitalization. Extracorporeal circulation, intra-aortic balloon pump, renal inadequacy before surgery, diabetes and peripheral vascular disease are all risk factors of ARF after operation. These factors can lead to ARF by constriction of capacitance vessel, filling defect of renal and ischemia-reperfusion injury et al. Appropriate drug treatment, haemodialysis and hemofiltration could protect renal function and improve prognosis of ARF.
Objective By means of evidence-based clinical practice, to find more effective treatment for a hepatitis B related nephritis patient with renal failure. Methods The following databases as Up to Date (May 2011), The Cochrane Library (Issue 5, 2011), PubMed (1978 to 2011) and CNKI (1978 to 2011) were searched to identify systematic reviews and randomized controlled trials (RCTs) of treating hepatitis B related nephritis with glucocorticoid, immunosuppressor or antiviral therapies, and the quality of collected clinical evidence was evaluated by using GRADEpro software. Results The glucocorticoid or combined immunosuppressors was not recommended for existing adverse effects and not acting on the remission of hepatitis B related nephritis and reduction of proteinuria. However, the antiviral therapy used alone was recommended for acting on the remission of hepatitis B related nephritis and the reduction of proteinuria. In view of adverse effects and expensive price of interferon, the nucleoside analogue antiviral agent was suggested. Considering the renal toxicity of adefovir and tenofovir, and possible drug-resistance of lamivudine, the entecavir (0.5 mg qd) was finally selected with patient’s agreement, and the supporting therapies such as lowering blood pressure, and protecting the kidney and liver were adopted continually. After one month treatment, 24-hour urinary protein got reduced, serum albumin got increased, kidney function got stable, and hepatitis B virus DNA quantity got reduced. Conclusion For treating hepatitis B related nephritis with kidney failure, entacavir can reduce 24-hour urinary protein, raise serum albumin, stabilize kidney function and reduce hepatitis B virus DNA in a short term, but its long-term efficacy still requires further studies.
