BACKGROUND: A total plasma exchange was the first extracorporeal method to treat patients with severe hypercholesterolemia. But in the long run it has several disadvantages. The newer lipoprotein apheresis (LA) methods claim to be more selective with respect to the removal of atherogenic lipoproteins and thus are supposed to avoid an additional protein loss. METHODS: We wanted to compare the effect of these methods on serum protein concentrations (total serum protein, albumin, proteins measured with electrophoresis, immunoglobulins, fibrinogen, transferrin, and ferritin) which were checked before and after a single LA session in 75 patients...

BACKGROUND: A protocol for ABO-incompatible kidney transplantation with antigen specific immunoadsorption, rituximab and conventional immunosuppression has been successfully implemented in many European centers. We report an alternative method for the elimination of isoagglutinins with a number of advantages - large amount of treatable plasma, parallel removal of other rejection-inducing antibodies, long operating life, favorable cost-benefit ratio. METHOD: We report our first successfully treated case of an ABO-incompatible living donor kidney transplantation using Immunoadsorption with Ig-TheraSorb...

We describe our experience with the performance of six lipoprotein apheresis methods (HELP, TheraSorb LDL, DALI, lipidfiltration, Liposorber D, MONET) which have been used in 68 patients. Thirty-four of them have been treated with more than one method. The calculations presented in this paper are based on laboratory data measured at the last three available apheresis sessions before the switch to another method and at the end of the observation period, respectively. With respect to the reduction of low-density lipoprotein (LDL) cholesterol, DALI and Liposorber D appeared to be the most effective lipoprotein apheresis methods, for reduction of lipoprotein(a), Liposorber D...

INTRODUCTION: Pathogenic autoantibodies (Abs) are a hallmark of SLE and their rapid removal is beneficial in active SLE. Immunoadsorption (IAS) is effective in removing serum levels of all classes of immunoglobulin (Ig), immune complexes (IC) and anti-dsDNA Abs and appears superior to plasmapheresis with respect to side effects. IAS can be performed with different columns, which use different ligands to bind their target. In particular, high affinity columns are in the focus of interest...

OBJECTIVE: Patients with the heterozygous form of familial hypercholesterolemia (FH) display an early onset of atherosclerosis due to disturbed vascular-endothelial function. Whether the improvements of endothelial function after lipid apheresis are mediated by increased NO-production or by an altered turnover of vasoconstrictors such as ET-1 is still unknown. This was the onset of the present study. METHODS: Patients with FH and advanced atherosclerosis receiving regular LDL apheresis at 1 to 3 weeks were recruited...

The first apheresis center in former German Democratic Republic was established in Dresden November 1990 following the reunification of Germany. We here summarize the activities of this center to date. From the center's establishment until the end of July 2009 13,291 sessions of therapeutic apheresis have been performed. Four LDL apheresis methods, namely DALI, Therasorb LDL, HELP and lipidfiltration, are available and several comparative studies of these methods have been published. In addition, we have established the Therasorb IG method and two rheophoresis methods (Rheofilter SR 20; TheraSorb-Rheo Adsorber)...

Pemphigus vulgaris (PV) is caused by autoantibodies to desmogleins. Standard immunosuppressive therapy may be limited by concomitant diseases or ineffective.In these cases, removal of circulating antibodies by immunoadsorption can induce remission. An 87-year-old woman with PV and considerable co-morbidities suffered from extensive mucous membrane erosions and bouts of skin blistering refractory to treatment with methotrexate,as well as mycopheno-late mofetil and corticosteroids even when combined with plasmapheresis and intravenous immunoglobulin...

BACKGROUND: Fibrinogen is mainly responsible for determining the viscosity of whole blood. In peripheral arterial disease (PAD) the fibrinogen concentration seems to affect the microcirculation flow. AIM: To study the effects of an abrupt reduction of fibrinogen on the hemodynamics of the lower extremities and the clinical picture of patients with PAD. METHODS: Ten patients affected by various stages of PAD underwent 1 session of fibrinogen apheresis (TheraSorb, Miltenyi Biotec, Germany)...

Efficiency of sorbents for LDL apheresis was compared in vitro. The sorbents based on ion-exchange interaction of the ligand with LDL (Liposorber, DALI) exhibited minimum specificity towards the eliminated component, while immunosorbents (LNP-Lipopak, LDR-TheraSorb) were most efficient. By sorption capacity, the available hemosorbents are inferior to plasmasorbents, which explains low efficiency of the therapy based on single application of hemosorbents especially in patients with consederably increased content of LDL cholesterol...

Therapeutic apheresis is an extracorporeal blood purification method for the treatment of diseases in which pathological proteins or cells have to be eliminated. Selective plasma processing is more efficient in pathogen removal than unselective plasma exchange and does not require a substitution fluid like albumin. This overview presents the various selective devices for the treatment of plasma (plasmapheresis) and blood cells (leukocyte apheresis). Prospective randomized trials were performed for the treatment of age-related macular degeneration (Rheopheresis), sudden hearing loss (heparin-induced lipoprotein precipitation [HELP]), rheumatoid arthritis (Prosorba), dilative cardiomyopathy (Ig-Therasorb, Immunosorba), acute-on-chronic liver failure (molecular adsorbent recirculating system [MARS]), and ulcerative colitis (Cellsorba)...

INTRODUCTION: Hyperacute xenograft rejection (HXR) and acute vascular rejection (AVR) after xenotransplantation are triggered by xenoreactive antibodies (XAb) and an activated complement cascade. In a heterotopic (abdominal) xenotransplantation model we combined immunoadsorption (IA, Ig-Therasorb column) and a quadruple immunosuppressive drug therapy in recipient baboons with donor pig hearts transgenic for human decay accelerating factor (hDAF). METHODS: According to XAb titers between 6 and 14 cycles of IA were performed preoperatively in 4 recipient baboons (18...

Inhibitors of factor VIII or FIX in haemophilic patients are a common and serious complication associated with an increased risk of life-threatening bleeding during elective surgery. Substitution therapy fails to be effective, therefore an alternative treatment is needed. We have performed six major elective orthopaedic interventions in four patients with haemophilia A and inhibitors. A preoperative immunadsorbant therapy with Therasorb to eliminate inhibitors was successful in four cases, but during FVIII substitution inhibitors increased on day 4 to day 6 after surgery, leading to decreasing FVIII levels...

OBJECTIVE: Recent studies have shown that immunoadsorption (IA) leads to improvements in left ventricular function and in functional status in selected patients with idiopathic dilated cardiomyopathy (DCM) and circulating autoantibodiesautoantibod. Most of the few studies dealing with this topic describe only short-term results. The aim of this study was to ascertain the prolonged effects of IA over a period of 3 years. MATERIALS AND METHODS: Our study included nine patients with circulating beta1-adrenoreceptor antibodies who suffered from idiopathic DCM (left ventricular ejection fraction <30%)...

BACKGROUND: Immunoadsorption is increasingly used to treat antibody-mediated autoimmune diseases. To prevent microbial growth during storage, reusable protein A-Sepharose gel columns are primed with ethyl mercury thiosalicylate (thiomersal, 0.1% solution) and rinsed with phosphate buffer before use. In this study, we tested the hypothesis of systemic mercury exposure in protein A immunoadsorption. METHODS: Whole blood mercury levels were measured by atomic absorption spectroscopy before and after protein A immunoadsorption (11 patients, 26 treatments), anti-IgG immunoadsorption (eight patients, 13 treatments) and LDL apheresis (DALI and Therasorb systems; nine patients, 14 treatments)...

Delayed donor red cell engraftment and prolonged red cell aplasia (PRCA) are well-recognized complications of major ABO-incompatible myeloablative and non-myeloablative hematopoietic stem cell transplantation (HSCT). There is an intense debate about the impact on outcome, severity of hemolysis, association with graft-versus-host disease and survival after blood group-incompatible stem cell transplantation. Therefore, therapeutic strategies should be considered to avoid these possible complications. We present five patients, who received allogeneic HSCT from human leukocyte antigen-identical donors for hematological malignancies, which were treated with Ig-Therasorb immunoadsorption (five treatments/week) to remove persisting incompatible isohemagglutinins...

BACKGROUND: Major ABO-incompatibility can be associated with haemolysis, prolonged red cell aplasia (PRCA) and higher peri-transplant mortality resulting from organ toxicity after conventional and non-myeloablative allogeneic haematopoietic stem cell transplantation. Different therapeutic strategies have been developed to allow erythroid reconstitution in these patients. METHODS: We present three patients, who developed PRCA after non-myeloablative allogeneic haematological stem cell transplantation for haematological malignancies...
