Objective To study the clinical protective effect of hemoperfusion combined with hemofiltration on inflammatory reaction of hyperlipidemia severe acute pancreatitis (HLSAP). Methods Thirty-seven patients with HLSAP treated between January 2012 and December 2014 were selected and divided into three groups based on different treatments. Thirteen patients were allocated into hemoperfusion combined with continuous veno-venous hemofiltration group (HP+CVVH group) and treated with hemoperfusion combined with hemofiltration; 11 patients were allocated into continuous veno-venous hemofiltration group (CVVH group) and treated with hemofiltration; and all the other patients were allocated into control group and treated with conventional treatment. The levels of blood triglyceride, C-reactive protein, tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-8 (IL-8) and acute physiology and chronic health evaluation (APACHE)Ⅱ score of the patients after treatment were observed. The hospital stay, organ dysfunction rate and mortality of the patients were measured. Results Compared with the control group, the levels of blood triglyceride, C-reactive protein, TNF-α, IL-6, IL-8 and APACHE Ⅱ score of the patients in the HP+CVVH group and CVVH group were both significantly reduced 72 hours after therapy (P<0.05). However, the levels of blood triglyceride, C-reactive protein, TNF-α, IL-6, IL-8 and APACHE Ⅱ score of the patients in the HP+CVVH group were significantly lower than those in the CVVH group at the same time point (P<0.05). The hospital stay of the patients in the HP+CVVH group and CVVH group was significantly shorter than that in the control group (P<0.05). Compared with the CVVH group, the hospital stay of patients in the HP+CVVH group was significantly shorter (P<0.05). There was no statistical difference in organ dysfunction rate and mortality among the three groups (P>0.05). Conclusion Hemoperfusion combined with hemofiltration is an effective method for HLSAP by cleaning the inflammatory mediators availably and inhibiting the excessive inflammatory reaction.
ObjectiveTo investigate the effect of polymyxin B hemoperfusion on the prognosis of patients with sepsis and septic shock by meta-analysis.MethodsSupplemented by manual search and document traceability, the US National Library of Medicine Pubmed, the Dutch Medical Abstracts Embase database, and the Cochrane clinical trial database were searched. Randomized controlled trials (RCTs) were collected from January 1998 to October 2018 for the treatment of sepsis and septic shock with polymyxin B hemoperfusion, only limited to English publications. The collected RCTs were evaluated and the prognosis of patients with sepsis and septic shock was analyzed by the Cochrane Collaboration.ResultsFinally six RCTs were included, and a total of 926 patients were analyzed, with 471 patients in the polymyxin B hemoperfusion group and 455 patients in the control group. The mortality rate was 36.3% (171/471) in the polymyxin B hemoperfusion group and 39.1% (178/455) in the control group. Hemoperfusion with polymyxin B could not reduce the patient mortality (RR=0.80, 95% CI 0.56 to 1.15, P=0.233). A subgroup analysis was taken on the patients with moderate to severe septic shock. Four RCTs were included in total and 418 patients were analyzed, with 207 patients in the polymyxin B hemoperfusion group and 211 in the control group. The mortality rate was 38.65% (80/207) in the polymyxin B hemoperfusion group and 50.71% (107/211) in the control group were. The hemoperfusion of polymyxin B could significantly reduce the mortality of patients with moderate to severe septic shock (RR=0.70, 95% CI 0.52 to 0.96, P=0.025).ConclusionsOlymyxin B hemoperfusion can not improve the prognosis of patients with sepsis and septic shock. However, compared with conventional treatment, polymyxin B hemoperfusion can improve the 28-day mortality rate of patients of severe septic shock. Due to the limit number of randomized controlled trials, more high-quality trials are needed to a further confirmation.
Objective To explore the clinical effect of hemoperfusion (HP) in cardiopulmonary bypass (CPB) on postoperative inflammation in patients with acute type A aortic dissection (AAD). MethodsAdult patients with AAD who planned to undergo total aortic arch replacement from July 2020 to November 2021 were continuously enrolled in our heart center. Patients were randomly divided into a HP group and a control (C) group. The HP group was treated with disposable HP device (Model: HA380, Zhuhai Jafron Biomedical, China) in CPB during the operation. ResultsFinally, 70 patients were included with 59 males and 11 females at an age range of 21-67 years. There were 35 patients in both groups. In this study, 3 patients died within 3 days after surgery, 2 in the HP group and 1 in the C group, and the remaining 67 patients survived to the follow-up end point (30 days after surgery). There was no statistical difference in preoperative baseline data, operative method, CPB time, block time, or other intraoperative data between the two groups. Blood product dosage, intubation time, hospital stays, and hospitalization expenses were similar between the two groups. Intraoperative hemoglobin (82.70±2.31 g/L vs. 82.50±1.75 g/L, P=0.954] and platelet concentration [(77.87±7.99)×109/L vs. (89.17±9.99)×109/L, P=0.384] were not statistically different between the HP group and C group. In the HP group, postoperative (ICU-12 h) interleukin-6 (IL-6) [338.14 (128.00, 450.70) pg/mL vs. 435.75 (180.50, 537.00) pg/mL, P=0.373], IL-8 [35.04 (18.02, 40.35) pg/mL vs. 43.50 (17.70, 59.95) pg/mL, P=0.383], and IL-10 [21.19 (6.46, 23.50) pg/mL vs. 43.41 (6.34, 50.80) pg/mL, P=0.537] were slightly lower than those in the C group, and the difference was not statistically different. The incidences of pulmonary infection (0.00% vs. 11.76%, P=0.042) and liver injury (2.94% vs. 20.58%, P=0.027) in the HP group were significantly lower than those in the C group, and the incidence of other postoperative complications, such as arrhythmia, nervous system complications and urinary system complications, showed no statistical difference between the two groups. Conclusion HP therapy in CPB is safe, but its effect on reducing postoperative inflammatory factors, postoperative inflammatory reactions and postoperative complications in the patients with AAD is limited, and it may be of application value to some high-risk patients with lung and liver injury.
Objective To explore the safety and efficacy of regional citrate anticoagulation in hemoperfusion combined with continuous renal replacement therapy (CRRT). Methods Patients who underwent continuous veno-venous hemodiafiltration tandem hemoperfusion between January 2021 and March 2022 in West China Hospital of Sichuan University were retrospectively enrolled. All patients received double-lumen catheter indwelling through internal jugular vein or femoral vein for vascular access, and were treated with Prismaflex V8.0 CRRT machine, extracorporeal circulation line ST150, and disposable hemoperperfusion device HA380. Four percent sodium citrate was pumped from the arterial end at the rate of 180-200 mL/h. The blood pump rate was 130-150 mL/min, the ratio of dialysis fluid to the dose of replacement fluid was 1∶1, the amount of CRRT treatment agent was 20-35 mL/(kg·h), replacement fluid was added by post-dilution method, and the treatment time of hemoperfusion was 8-10 h. The dialysis treatment completion rate, the cardiopulmonary bypass life, the incidence of coagulation events, and the levels of procalcitonin, C-reactive protein, interleukin-6, etc. were observed. Results A total of 143 cases of treatment were completed in 75 patients, among them, 119 cases were successfully completed and the completion rate of hemoperfusion treatment was 83.2%. The average life of hemoperfusion devices was (8.5±1.5) h. Bleeding or blood clotting occurred in 18.9% of the treatment (27/143), 13 cases had CRRT extracorporeal circulation coagulation, 11 cases had hemoperfusion device coagulation, and 3 cases had gastrointestinal bleeding. The ionic calcium levels after the filter of 93 cases of treatment were maintained around 0.25-0.35 mmol/L, and the peripheral calcium levels were maintained around 1.0-1.1 mmol/L. Compared with that at 0 h, the procalcitonin decreased significantly 72 h after hemoperfusion treatment (P=0.014), while there was no significant change in interleukin-6 or C-reactive protein after 72 h treatment (P>0.05). None of the patients experienced anaphylaxis during treatment. Conclusion In CRRT combined with hemoperfusion, the use of regional citrate anticoagulation results in good cardiopulmonary bypass life, inflammatory mediators clearance, and a lower risk of bleeding.
We established acute cholangitis and endotoxiemia in 18 rabbits by ligating the common bile duct and injecting E coli(O111B4 strain)into the common bile duct. After perfusion through activated charcoal via femoral artery-vein pathway, the average blood levels of endotoxin decreased sighificantly from 2.24Eu/ml to 0.17Eu/ml(Plt;0.001). This result suggested that blood perfusion through activated charcoal may be a promising therapy for acute endotoxemia.
目的 觀察三種不同血液凈化方式[血液透析（HD）、血液透析濾過（HDF）、血液透析+血液灌流（HD+HP）]對維持性血液透析患者高磷血癥清除效果。 方法 選擇2009年2月－2011年2月行維持性血液透析的48例高磷血癥患者為研究對象，所有患者在低鈣透析（1.25 mmol/L）的基礎，隨機分為HD組、HDF組、HD+HP組，每組16例，分別在治療時及治療后4周、8周檢查鈣、磷、鈣磷乘積和全段甲狀旁腺激素，并觀察其變化。 結果 在治療4周、8周后，HDF組、HD+HP組磷較前均顯著下降（P值均＜0.05），兩組同時點相比較差異無統計學意義（P＞0.05）；HD組較前血磷無明顯變化（P＞0.05）。 結論 HDF、HP清除維持性血液透析患者高磷有顯著的效果，而HD效果則不佳。

目的 通過比較三種血液凈化方式對炎癥介質、甲狀旁腺激素等中大分子毒素的清除效果，并觀察促紅細胞生成素（EPO）的治療效果，探尋有利于腎性貧血改善的最佳透析模式。 方法 2011年5月－8月采用前瞻性、隨機對照、開放式設計，選擇維持性血透患者60例，隨機分成3組，每組20例。血液灌流（HDP）組[每2周5次血液透析（HD）+1次HDP]、血液透析濾過治療（HDF）組（每2周5次HD+1次HDF）、HD組（每2周6次HD），隨訪3個月。檢測試驗前后反應蛋白（CRP）、β2微球蛋白、甲狀旁腺素（PTH）、白介素-6的水平以及各組患者腎性貧血指標的變化。 結果 3個月試驗結束時，HDP組和HDF組4項尿毒癥毒素水平均顯著下降，其中HDP組CRP水平明顯低于HDF組（P＜0.05）；HDP組和HDF組試驗后的血紅蛋白水平較試驗前升高，ERI值下降。HD組試驗前后的毒素水平無明顯變化，ERI值升高。3組患者均未出現嚴重不良事件。 結論 HDP和HDF清除中大分子毒素的能力優于HD，有利于緩解微炎癥狀態，改善EPO治療效果。HDP和HDF的遠期效果哪種更好，尚有待于進一步的研究。
Objective To investigate the therapeutic effect of continuous renal replacement therapy (CRRT) plus hemoperfusion (HP) on patients with diabetes and uremic encephalopathy. Methods Fifty-five patients with diabetes and uremic encephalopathy from January 2010 to December 2017 were retrospectively collected in this study and divided into CRRT plus HP (CRRT+HP) group (n=28) and hemodialysis (HD) plus HP (HD+HP) group (n=27). The changes of vital signs, related biochemical indicators before and after treatment and curative effects were compared between the two groups. Results The two groups were comparable in general. No significant differences were found in blood pressure or heart rate before and after treatment between the two groups (P>0.05). The incidence of hypotension events in CRRT+HP group was significantly lower than that in HD+HP group (P<0.05), and the effective rate of cardiac function improvement in CRRT+HP group was significantly higher than that in HD+HP group (P<0.05). After treatment, the blood urea nitrogen, creatinine, parathyroid hormone, β2-microglobulin, phosphorus, C-reactive protein and brain natriuretic peptide in the two groups were significantly decreased than those before treatment (P<0.05). Parathyroid hormone, β2-microglobulin, C-reactive protein and brain natriuretic peptide were significantly decreased in CRRT+HP group as compared with those in HD+HP group (P<0.05). The remission rate of uremic encephalopathy in CRRT+HP group was significantly higher than that in HD+HP group (P<0.05). Conclusions As compared with HD+HP pattern, CRRT+HP pattern is more stable in the hemodynamics, and more effective in the improvement of heart failure and the clearance of inflammatory mediators, middle molecular and macromolecular substances associated with uremic encephalopathy. CRRT+HP pattern is suitable for the treatment of patients with diabetes and uremic encephalopathy.
