The effects of a filgrastim dose of 8 microg/kg/day were not significantly different from those of a dose of 16 microg/kg/day. In the group of patients receiving 8 microg/kg/day, the CD34+ cells over 3 x 10(6)/kg donor body weight were harvested in 3 patients who did not have a long history of receiving combination chemotherapy. The administration of 8 microg/kg filgrastim was adopted also for allogeneic PBSC mobilization for 24 healthy donors. All healthy donors donated an adequate number of PBSCs (CD34+ cells over 4 x 10(6)/kg of recipient body weight) and tolerated this mobilization well with no serious complications.

In order to perform living-donor liver transplantations under safer conditions, apheresis plays a major role in Japan due to the prevalence of living-donor liver transplantation wherein later retransplantation is difficult. In our department, the roles of apheresis in liver transplantation are as follows: as bridge therapy to liver transplantation (n = 45); as a supplement to the graft liver until the recovery of hepatic function (n = 77); as treatment for multiple organ failure including posttransplantation renal failure (n = 15); and as a means with which to reduce antibody titers for antibodies such as anti-A or anti-B in persons with ABO blood type = incompatible liver transplantation (n = 23). In our department, we have performed 822 liver transplantations at present. Of those cases, 183 were selected wherein apheresis was performed around the time of the operation. In all cases, transplantation with sufficient apheresis was performed before the surgical operation, however, 22 patients (48.9%) died after undergoing surgery. Among the patients who underwent the postoperative apheresis, those in the nonsurvivor group had lower grafted liver weights compared to those of the survivor group. The kidney was the organ that most frequently failed due to postoperative complications. In cases of ABO blood type-incompatible liver transplantations, patients with high preoperative anti-A/B IgM antibody titers sustained bile duct complications, patients with high preoperative anti-IgG antibody titers sustained hepatic necrosis, and patients with high postoperative anti-A/B IgM and anti-IgG antibody titers sustained hepatic necrosis most frequently.</p>","PeriodicalId":79755,"journal":{"name":"Therapeutic apheresis : official journal of the International Society for Apheresis and the Japanese Society for Apheresis","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1046/j.1526-0968.2002.00460.x","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"22136327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The adsorbent has dual ligands in order to improve the specific binding affinity for glc-LDL that consisted of boronic acid moiety for the glycosylated site and acrylic acid (AA) moiety for the apolipoprotein B of LDL. The adsorbent was synthesized by copolymerization of 4-vinyl phenyl boronic acid and AA. Five kinds of copolymers having different compositions were prepared and evaluated in terms of glc-LDL in vitro adsorption in human plasma. The adsorption behaviors were different depending on the polymer composition. The adsorbent having the AA composition from 50% to 90% showed very high selectivity for glc-LDL adsorption.
