In recent years, immunoadsorption has been increasingly recognized as an alternative to therapeutic plasma exchange and used for the treatment of neurological disorders such as Guillain-Barré syndrome, chronic inflammatory demyelinating polyneuropathy, myasthenia gravis, neuromyelitis optica spectrum disorders, and multiple sclerosis, as well as autoimmune encephalitis. Unlike therapeutic plasma exchange, which requires fluid replacement with a blood solution such as fresh frozen plasma or albumin, immunoadsorption is a blood purification technique that enables the selective removal of humoral factors from separated plasma through a high-affinity adsorbent with tryptophan or phenylalanine...

Organ transplantation represents the preferred treatment option for many patients in terminal organ failure. The half-life of transplanted organs, however, is still far from being satisfactory with the vast majority of the organs failing within the first two decades following transplantation. At this stage, it has become apparent that rejection (prevalently mediated by humoral events) remains the primary cause of graft loss after the first year. In this light, studies are underway to better comprehend the immune events underlying graft rejection and novel immunosuppressive strategies are being explored...

Myasthenia gravis (MG) is caused by autoantibodies, the majority of which target the muscle acetylcholine receptor (AChR). Plasmapheresis and IgG-immunoadsorption are useful therapy options, but are highly non-specific. Antigen-specific immunoadsorption would remove only the pathogenic autoantibodies, reducing the possibility of side effects while maximizing the benefit. We have extensively characterized such adsorbents, but in vivo studies are missing. We used rats with experimental autoimmune MG to perform antigen-specific immunoadsorptions over three weeks, regularly monitoring symptoms and autoantibody titers...

Autoantibodies play an important role in the pathophysiology of renal involvement in systemic autoimmune diseases, such as systemic lupus erythematosus (SLE), systemic vasculitis, and anti-glomerular basement membrane disease (or Goodpasture syndrome). Direct removal of autoantibodies therefore has been tried in various ways, first by plasma exchange. Today, immunoadsorption is the extracorporeal method that most effectively removes (pathogenic) immune complexes and antibodies. Although past data have shown efficacy and biocompatibility of immunoadsorption in (renal) SLE, it is still an experimental and expensive procedure, and evidence from randomized controlled trials is needed...

INTRODUCTION: Nonobstructive cholestasis after pediatric liver transplantation is a common diagnostic and therapeutic dilemma. We describe a girl with neonatal cholestasis because of progressive familial intrahepatic cholestasis 2 (PFIC-2) and presence of a homozygous splice site mutation in the ABCB11 gene. Liver transplantation was performed because of end-stage liver disease at the age of 6. Cholestasis with normal gamma-glutamyl transferase (GGT) developed 8 years after liver transplantation...

INTRODUCTION: Neurofascin155 (NF155) is a target antigen for autoantibodies in a subset of chronic inflammatory demyelinating polyneuropathy (CIDP). METHODS: We report the cases of 4 patients with anti-NF155 immunoglobulin G4 (IgG4) antibody-positive CIDP who underwent sural nerve biopsies. RESULTS: All patients were relatively young at onset. Three patients experienced tremors, and 2 patients had severe ataxia. Although the response to intravenous immunoglobulin was poor in all patients, plasma exchange and corticosteroids were at least partially effective...

OBJECTIVES: Autoantibodies to the dense fine speckled 70 (DFS70) antigen are common among antinuclear antibodies (ANA) positive healthy individuals (HI). We assessed the prevalence of anti-DFS70 antibodies in patients with and without ANA-associated rheumatic diseases (AARDs) by two methods: chemiluminescent immunoassay (CIA) and an indirect immunofluorescence (IIF) assay based on immunoadsorption for DFS70. METHODS: Fifty-one ANA-positive sera samples from patients with confirmed clinical diagnosis of AARD, 92 samples from HI and 85 samples submitted to a reference laboratory for routine ANA testing were evaluated for the presence of anti-DFS70 antibodies...

Desensitisation is a procedure undergone by the recipient of a kidney transplant from a donor who is cross-match positive. The aim of this study was to present the outcomes from our hospital of kidney transplant recipients from HLA-incompatible live donors after desensitisation. We studied 32 patients aged 46±14 years with a mean fluorescence intensity (MFI) versus class I HLA of 7979±4089 and 6825±4182 MFI versus class II and relative intensity scale (RIS) of 8.9±7.6. The complement-dependent cytotoxicity (CDC) cross-matching test was positive in 18 patients, flow cytometry was positive in 7 patients and donor-specific antibodies (DEA) were detected in 7...

Herpes simplex virus-1 has been identified as the trigger factor in certain cases of NMDA-receptor autoimmune encephalitis. We report on a 67-year-old female patient, who was severely affected by post-herpetic NMDA-receptor autoimmune encephalitis. Her symptoms did not improve under methylprednisolone pulse therapy and plasma exchange under acyclovir prophylaxis. She received protein A immunoadsorption and a long-term immunosuppression with rituximab. Under treatment, activated T-cells as well as B- and plasma cells decreased in peripheral blood and cerebrospinal fluid, and anti-NMDA-R IgG titers in serum and cerebrospinal fluid declined with near complete cessation of intrathecal autoantibody synthesis...

Immunoadsorption with a tryptophan-conjugated column has a limited capacity and reduces fibrinogen. We speculated that immunoadsorption with a selective plasma separator has higher efficiency in removing immunoglobulins than ordinary immunoadsorption without affecting coagulation factors. This study investigated the efficacy of immunoadsorption with a selective plasma separator in vitro. The sieving coefficients, the pool concentration, and the adsorbed amount were investigated serially with up to 5 L of processed plasma...

INTRODUCTION: Despite prophylaxis, a small proportion of RhD-negative women may develop anti-D antibodies after a sensitizing event occurring during pregnancy or delivery of a D-positive baby. Intrauterine transfusion (IUT) is the treatment of choice in case of fetal anemia, but it cannot be performed early during pregnancy. Combined treatment with therapeutic plasma-exchange (TPE) and intravenous immunoglobulin (IVIG) can avoid or delay IUT. Immunoadsorption (IA) could represent a more effective treatment in selected cases...

Apheresis has been used in the treatment of severe systemic vasculitides, in conjunction with immunosuppressive therapies, for over 40 years. The aim is to rapidly remove autoantibodies or circulating immune complexes from the plasma. The two main indications at present are vasculitis associated with Antineutrophil Cytoplasmic Antibodies (ANCAs) manifesting as severe renal involvement and/or intraalveolar hemorrhage and antiglomerular basement membrane disease (Goodpasture syndrome). The ongoing PEXIVAS randomized controlled trial is assessing plasmapheresis to treat ANCA-associated vasculitis with or without severe renal involvement or intraalveolar hemorrhage...

In times of organ shortage, transplantation over the blood group A/B and HLA antibody barriers helps increasing the living donor pool in kidney transplantation. Waiting times are reduced while patient survival may be improved. By desensitization, both blood group A/B as well as HLA antibodies are eliminated from the patient's circulation using plasmapheresis, double filtration plasmapheresis or selective or unselective immunoadsorption. In addition, antibody production and posttransplant antibody rebound are prevented by powerful immunosuppression and induction therapy with or without B-cell eliminating anti-CD20 antibody rituximab...

BACKGROUND: Since 1996, ABO-incompatible heart transplantation has been undertaken by performing whole-body plasma exchange to remove isohemagglutinins using the cardiopulmonary bypass (CPB) circuit at the time of transplantation. This requires large volumes of donated blood and blood products, causes hemodynamic instability during the exchange transfusion, and limits practical use to small children. We sought to determine the efficacy of anti-A/B immunoadsorption within the CPB circuit on removal of isohemagglutinins in an ex vivo setting before its use clinically...

In recent years, immunological barriers historically considered as absolute contraindications to transplantation are being reevaluated. One such barrier is the ABO blood group incompatibility. With better understanding of immunological mechanisms and effective various regimens for controlling it, ABO-incompatible (ABO-I) kidney transplantation is now being performed with increasing frequency. For good outcome, most important is to achieve and maintain low anti-blood group antibody titers (ABGATs). Twenty-two patients with ABO-I donors have been studied...
