Relapsed patients with BALL after ...Leukemia relapse is still the leading cause of treatment failure after allogeneic hematopoietic stem cell transplantation (allo-HSCT) for B cell acute lymphoblastic leukemia (B-ALL). Relapsed patients with BALL after allo-HSCT have a very short median survival. Minimal residual disease (MRD) is predictive of forthcoming hematological relapse after hematopoietic stem cell transplantation (HSCT);furthermore, eliminating MRD effectively prevents relapse. Donor lymphoblastic infusion (DLI) is the main established approach to treat B-ALL with MRD after allo-HSCT. However, about one-third of patients with MRD are non-responsive to DLI and their prognosis worsens. Although donor-derived cluster of differentiation (CD)19-directed chimeric antigen receptor-modified (CAR) T cells (CART19s) can potentially cure leukemia, the efficiency and safety of infusions with these cells have not yet been investigated in patients with MRD after HSCT. Between September 2014 and February 2018, six patients each received one or more infusions of CART19s from HSCT donors. Five (83.33%) achieved MRD-negative remission, and one case was not responsive to the administration of CAR T cells. Three of the six patients are currently alive without leukemia. No patient developed acute graft-versus-host disease (aGVHD), and no patient died of cytokine release syndrome. Donor-derived CAR T cell infusions seem to be an effective and safe intervention for patients with MRD in B-ALL after allo-HSCT and for those who were not responsive to DLI.展开更多

Twenty Japanese white rabbits were enrolled and propofol(10 mg/kg) was administrated intravenously. Artery blood samples were collected at various time points after injection, and plasma concentrations of propofol were measured. Pharmacokinetic modeling was performed using Win Nonlin software. Propofol TCI within the acquired parameters integrated was conducted to achieve different anesthetic depths in rabbits, monitored by narcotrend. The pharmacodynamics was analyzed using a sigmoidal inhibitory maximal effect model for narcotrend index(NI) versus effect-site concentration. The results showed the pharmacokinetics of propofol in Japanese white rabbits was best described by a two-compartment model. The target plasma concentrations of propofol required at light anesthetic depth was 9.77±0.23 μg/m L, while 12.52±0.69 μg/m L at deep anesthetic depth. NI was 76.17±4.25 at light anesthetic depth, while 27.41±5.77 at deep anesthetic depth. The effect-site elimination rate constant(ke0) was 0.263/min, and the propofol dose required to achieve a 50% decrease in the NI value from baseline was 11.19 μg/m L(95% CI, 10.25–13.67). Our results established a new propofol TCI animal model and proved the model controlled the anesthetic depth accurately and stably in rabbits. The study provides a powerful method for exploring general anesthetic mechanisms at different anesthetic depths in vivo.展开更多

This study evaluated the accuracy and feasibility of TCI system for sufentanil at high concentrations in Chinese surgical patients. Methods Twelve low risk adult patients undergoing elective surgery under general anesthesia were included in this study. Sufentanil was administered with a specific TCI system incorporating the population pharmacokinetic data of sufentanil previously reported, using a target effect-site concentration of sufentanil 4 or 6 ng/ml. Sufentanil TCI duration was 30 minutes. Frequent arterial blood samples were taken during and up to 24 hours after sufentanil TCI for determination of plasma sufentanil concentrations by liquid chromatography-mass spectrometry/mass spectrometry. The changes of circulatory system function during the procedure, recovery profile and adverse effects were recorded. Measured plasma sufentanil concentrations were compared with the values predicted by the TCI system. The bias (median performance error, MDPE), precision (median absolute performance error, MDAPE) and wobble (variability of performance error) of the sufentanil TCI system were determined. Results All patients had stable cardiovascular variables during induction and maintenance of anesthesia. Time to eye opening and extubation were (5.6±1.7) minutes when TCI set to 4 ng/ml and (7.2±2.3) minutes when set to 6 ng/ml. There was no episode of agitation, muscle rigidity or intraoperative awareness. The bias (MDPE), precision (MDAPE) and wobble of the sufentanil TCI system were -3.7%, 18.9% and 19.6% respectively during TCI, and the MDPE, MDAPE and wobble were -29.1%, 31.7% and 15.0% respectively after TCI (up to 8 hours). Conclusions The TCI system programmed for sufentanil at 4 or 6 ng/ml was considered acceptable for clinical use in low risk Chinese surgical patients. But the relatively larger MDPE and MDAPE after TCI suggest improvements of the Dharmacokinetic model are needed.展开更多

The current study was to estimate the pharmacokinetics of sufentanil TCI in Chinese patients using the two-stage analysis. Methods Twelve adult patients with American Society of Anesthesiologists (ASA) physical status I or II undergoing elective surgery under general anesthesia were included. Anesthesia was induced with propofol, rocuronium and sufentanil administered by TCI lasting for 30 minutes, with target effect-site concentration of sufentanil 4 or 6 ng/ml. Frequent arterial blood samples (1.5 ml) were taken during and up to 24 hours after sufentanil TCI. Before the end of surgery, another arterial blood sample (1.0 ml) was drawn for the blood-gas analysis. Plasma sufentanil concentrations were determined by liquid chromatography-tandem mass spectrometry (limit of quantitation was 5 pg/ml). The data were analyzed with the two-stage approach, linear regression and correlation analysis. Results The pharmacokinetics of sufentanil TCI were adequately described by a three-compartment model. The variables were derived as follows: the volume of central compartment (V1) was 5.4 L, volume of distribution at steady-state (Vdss) was 222.6 L, metabolic clearance (CI1) was 0.84 L/min and elimination half-life (t~/2y) was 389 minutes. Patients' age, gender and PaCO2 correlated significantly with the pharmacokinetic parameters. The Vdss, volume of slowly equilibrating compartment (V3) and t1/2 y increased, and rapid distribution clearance (012) decreased with increasing patient age. Male patients had larger values of Vdss, volume of rapidly equilibrating compartment (V2) and V3 than female patients. The Vdss and V3 increased with higher PaCO2 values. There were no significant correlations between the pharmacokinetic variables and body weight, height, lean body mass, plasma albumin, sufentanil dose, duration of surgery, pH or base excess of blood (BE-B). Conclusions The pharmacokinetics of sufentanil TCI in Chinese patients can be optimally described by a three-compartment model. The pharmacokinetic analysis technique may affect the pharmacokinetic parameters and correlations.展开更多

文摘目的 探讨CONCERT-CL闭环靶控输注系统在腹腔镜胃肠手术患者中的应用效果及对患者术后胃肠功能和免疫功能的影响。方法 选取2022年8月至2023年5月上海市徐汇区中心医院收治的80例腹腔镜胃肠手术患者作为研究对象,按随机数表法分为观察组和对照组各40例。两组患者均采用相同的麻醉方案,但观察组患者采用CONCERT-CL闭环靶控输注系统进行麻醉管理,而对照组患者则采用开放式麻醉维持。比较两组患者的围术期相关指标、胃肠功能和围术期白细胞分化抗原(CD) TT细胞数量和自然杀伤细胞(NK)细胞数量,同时比较两组患者术后不良反应发生情况。结果 观察组患者的手术时间、麻醉时间分别为(183.60±30.15) min、(206.69±10.54) min,对照组分别为(189.12±43.85) min、(211.65±16.83) min,差异均无统计学意义(P>0.05);观察组患者术中丙泊酚用量和顺式阿曲库铵用量分别为(13.34±2.00) mg/kg、(0.26±0.09) mg/kg,明显低于对照组的(15.96±1.41) mg/kg、(0.35±0.11) mg/kg,拔管即刻警觉-镇静(OAA/S)评分和术中BIS时间为40~60的占比分别为(3.46±0.25)分、(82.60±4.22)%,明显高于对照组的(3.12±0.46)分、(64.02±3.65)%,差异均有统计学意义(P<0.05);观察组和对照组患者的肠鸣音恢复[(22.60±4.52) h vs (30.57±6.84) h]、腹痛缓解[(26.88±4.11) h vs (30.17±2.94) h]、术后首次排气时间[(32.69±4.25) h vs (44.35±1.68) h]比较,观察组明显短于对照组,差异均有统计学意义(P<0.05);术后12 h,观察组和对照组患者的CD4+TT数量[(35.69±1.54)%vs (32.01±6.21)%]、NK细胞数量[(20.36±2.41)%vs (18.73±2.65)%]比较,观察组明显高于对照组,CD8+TT数量[(27.01±1.79)%vs (29.28±3.87)%]比较,观察组明显低于对照组,差异均有统计学意义(P<0.05);观察组患者的不良反应总发生率为5.00%,略低于对照组的10.00%,但差异无统计学意义(P>0.05)。结论 CONCERT-CL闭环靶控输注系统在腹腔镜胃肠手术患者中的应用能够降低术中麻醉维持药物用量,患者苏醒速度更快。同时还能够促进患者术后胃肠功能的恢复,并且对免疫功能起到一定改善作用。
文摘Background Sufentanil is a suitable choice for target-controlled infusion (TCI) because of its shorter context-sensitive half-time. The current study was to estimate the pharmacokinetics of sufentanil TCI in Chinese patients using the two-stage analysis. Methods Twelve adult patients with American Society of Anesthesiologists (ASA) physical status I or II undergoing elective surgery under general anesthesia were included. Anesthesia was induced with propofol, rocuronium and sufentanil administered by TCI lasting for 30 minutes, with target effect-site concentration of sufentanil 4 or 6 ng/ml. Frequent arterial blood samples (1.5 ml) were taken during and up to 24 hours after sufentanil TCI. Before the end of surgery, another arterial blood sample (1.0 ml) was drawn for the blood-gas analysis. Plasma sufentanil concentrations were determined by liquid chromatography-tandem mass spectrometry (limit of quantitation was 5 pg/ml). The data were analyzed with the two-stage approach, linear regression and correlation analysis. Results The pharmacokinetics of sufentanil TCI were adequately described by a three-compartment model. The variables were derived as follows: the volume of central compartment (V1) was 5.4 L, volume of distribution at steady-state (Vdss) was 222.6 L, metabolic clearance (CI1) was 0.84 L/min and elimination half-life (t~/2y) was 389 minutes. Patients' age, gender and PaCO2 correlated significantly with the pharmacokinetic parameters. The Vdss, volume of slowly equilibrating compartment (V3) and t1/2 y increased, and rapid distribution clearance (012) decreased with increasing patient age. Male patients had larger values of Vdss, volume of rapidly equilibrating compartment (V2) and V3 than female patients. The Vdss and V3 increased with higher PaCO2 values. There were no significant correlations between the pharmacokinetic variables and body weight, height, lean body mass, plasma albumin, sufentanil dose, duration of surgery, pH or base excess of blood (BE-B). Conclusions The pharmacokinetics of sufentanil TCI in Chinese patients can be optimally described by a three-compartment model. The pharmacokinetic analysis technique may affect the pharmacokinetic parameters and correlations.
