Therapeutic apheresis and immunoadsorption are used to deplete efficiently pathogenic autoantibodies in crises in several acute autoimmune driven diseases. This prospective, non-comparative cohort study was conducted at a single study center under standardized conditions in 10 healthy volunteers. Efficient immunoglobulin G (IgG) removal (-86% versus baseline) was achieved after 3 apheresis treatments on 3 consecutive days. The treatments were well tolerated. Safety laboratory parameters did not show unexpected or pathological changes...

BACKGROUND: Chronic inflammatory demyelinating polyneuropathy (CIDP) is a rare paralyzing inflammatory neuropathy with probably autoimmune origin. While plasma exchange (PE) constitutes a first-line treatment option for CIDP, there is only little known about the efficacy and safety of immunoadsorption (IA), a more selective apheresis procedure with assumed better tolerability. METHODS: In this prospective-randomized pilot trial, patients were randomly assigned to receive 6 sessions of PE (n = 10) or IA (n = 10) treating equal plasma volumes...

Autoantibodies against cardiac proteins play an important role in the development of dilated cardiomyopathy (DCM). The efficacy and safety of apheresis such as immunoadsorption (IA) or plasma exchange (PE) to remove such antibodies have been reported in adult DCM patients. However, apheresis for pediatric DCM has not been performed because of technical difficulty due to relatively low blood volume and instability of hemodynamics. As we have experiences of preforming apheresis on hemodynamically unstable children, we have preformed ten courses of PE on seven child DCM patients including both patients in chronic and acute phase to assess the safety and efficacy to PE...

In 1984, we started using therapeutic plasmapheresis (plasma exchange) as a method of extracorporeal lipoprotein elimination for the treatment of hypercholesterolemic patients. We evaluated the results of long-term therapy in 14 patients, 8 men and 6 women. The average age was 55.6+/-13.2 (range 28-70), median 59.5 years. 14 patients were diagnosed with familial hypercholesterolemia (FH): 5 homozygous, 9 heterozygous. Ten patients in the group were treated using immunoadsorption lipoprotein apheresis and 4 using hemorheopheresis...

BACKGROUND: Chronic antibody injury is a serious threat to allograft outcomes and is therefore the center of active research. In the continuum of allograft rejection, the development of antibodies plays a critical role. In recent years, an increased recognition of molecular and histologic changes has provided a better understanding of antibody-mediated rejection (AMR), as well as potential therapeutic interventions. However, several pathways are still unknown, which accounts for the lack of efficacy of some of the currently available agents that are used to treat rejection...

A 63-year-old male was diagnosed with autoimmune autonomic ganglionopathy based on the finding of plasma antibodies to the nicotinic acetylcholine receptor (nAChR) of autonomic ganglia. He complained of mouth and eye dryness, dysphagia, severe constipation, erectile dysfunction, urgency, frequent urination, habitual orthostatic syncope and presyncope. A remarkable symptomatic orthostatic hypotension without changes in heart rate was present. We here describe the 3-year time course of the changes in spectral indices of cardiovascular autonomic control LF/HF and LFSAP, dysautonomia symptoms intensity and anti-nAChR antibodies following repetitive selective immunoadsorptions...

According to current knowledge, autoantibodies against 1-adrenergic receptors may be involved in pathogenesis of different cardiovascular diseases and are mostly studied in patients with Chagas disease, dilated cardiomyopathy and heart rhythm disorders. They may play an important role in cardiomyocyte apoptosis, alteration of their chrono- and inotropic effects and electrophysiological characteristics. Their effects are transduced via 1-adrenergic receptors and depend on multiple factors as ligand properties, durability of its coupling with the receptor, amount of receptors on the cell surface, their affinity and conformation...

BACKGROUND: Prevention of IgE-binding to cellular IgE-receptors by anti-IgE (Omalizumab) is clinically effective in allergic asthma, but limited by IgE threshold-levels. To overcome this limitation, we developed a single-use IgE immunoadsorber column (IgEnio). IgEnio is based on a recombinant, IgE-specific antibody fragment and can be used for the specific extracorporeal desorption of IgE. OBJECTIVE: To study safety and efficacy of IgEnio regarding the selective depletion of IgE in a randomized, open-label, controlled pilot trial in patients with allergic asthma and to investigate if IgEnio can bind IgE-Omalizumab immune complexes...

Autoimmunity is increasingly accepted as the origin or amplifier of various diseases. In contrast to classic autoantibodies (AABs), which induce immune responses resulting in the destruction of the affected tissue, an additional class of AABs is directed against G-protein-coupled receptors (GPCRs; GPCR-AABs). GPCR-AABs functionally affect their related GPCRs for activation of receptor mediated signal cascades. Diseases which are characterized by the presence of GPCR-AABs with evidence for disease-specific pathogenic activity could be named "functional autoantibody disease"...

The observation of acetylcholinesterase (AChE) type H (AChEH), which is the predominant AChE variant in visceral organs and immune cells, in lipid rafts of muscle supports functional reasons for the raft targeting of glypiated AChEH The search for these reasons revealed that liver AChE activity is mostly confined to rafts and that the liver is able to make N-extended AChE variants and target them to rafts. These results prompted us to test whether AChE and muscarinic receptors existed in the same raft. Isolation of flotillin-2-rich raft fractions by their buoyancy in sucrose gradients, followed by immunoadsorption and matrix-assisted laser desorption ionization-time of flight-mass spectrometry application, gave the following results: 1) most hepatic AChE activity emanates from AChE-H mRNA, and its product, glypiated AChEH, accumulates in rafts; 2) N-extended N-AChE readthrough variant, nonglypiated N-AChEH, and N-AChE tailed variant were all identified in liver rafts; and 3) M3 AChRs were observed in rafts, and coprecipitation of raft-confined N-AChE and M3 receptors by using anti-M3 antibodies showed that enzyme and receptor reside in the same raft unit...

Plasma exchange is a non-selective apheresis technique that can be performed by filtration or centrifugation allowing rapid purification of high molecular weight pathogens. An immunosuppressive treatment is generally associated to reduce the rebound effect of the purified substance. Substitution solutes such as human albumin and macromolecules are needed to compensate for plasma extraction. Compensation by viro-attenuated plasma is reserved solely for the treatment of thrombotic microangiopathies or when there is a risk of bleeding, because this product is very allergenic and expensive...

Many rheumatological diseases are either caused by specific known proteins, such as antibodies or mediated by a plethora of cytokines. Both the unspecific immunosuppressive therapy and the specific action of biologics usually require time to be effective; therefore, extracorporeal forms of treatment are increasingly being employed in severe forms of rheumatological diseases as well as in patients who cannot tolerate pharmacological treatment or where the risk of pharmacological treatment may outweigh the potential benefits...

Buerger's disease, also known as thromboangiitis obliterans (TAO), is a segmental inflammatory disease affecting small- and medium-sized vessels, which is strongly associated with tobacco use. Although the etiology is still unknown, recent studies suggest an immunopathogenesis. Diagnosis is based on clinical and angiomorphologic criteria, including age, history of smoking, clinical presentation with distal extremity ischemia, and the absence of other risk factors for atherosclerosis, autoimmune disease, hypercoagulable states, or embolic disease...
