Immunoadsorption as maintenance therapy for refractory neuromyelitis optica spectrum disorder.

Background: Neuromyelitis optica spectrum disorder (NMOSD) is a rare relapsing autoimmune disease of the central nervous system, affecting mainly optic nerves and spinal cord. NMOSD pathophysiology is associated with anti-aquaporin-4 (AQP4) immunoglobulin G (IgG) autoantibodies. Rapid extracorporeal elimination of autoantibodies with apheresis techniques, such as immunoadsorption (IA), was proven to be an effective treatment of NMOSD attacks.

First-in-Man: Case Report of Selective C-Reactive Protein Apheresis in a Patient with SARS-CoV-2 Infection.

BACKGROUND C-reactive protein (CRP) plasma levels in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel viral disease, are surprisingly high. Pulmonary inflammation with subsequent fibrosis in SARS-CoV-2 infection is strongly accelerated. Recently, we have developed CRP apheresis to selectively remove CRP from human plasma.

Lipoprotein apheresis in Germany - Still more commonly indicated than implemented. How can patients in need access therapy?

Background: Although lipid-lowering drugs, especially statins, and recently also PCSK9 inhibitors can reduce LDL cholesterol (LDL-C) and decrease the risk for cardiovascular disease (CVD) including coronary artery disease (CAD) events most efficiently, only 5-10% of high-risk cardiovascular patients reach the target values recommended by international guidelines. In patients who cannot be treated adequately by drugs it is possible to reduce increased LDL-C and/or lipoprotein(a) (Lp(a)) values by the use of lipoprotein apheresis (LA) with the potential to decrease severe CVD events in the range of 70%->80%. Even in Germany, a country with well-established reimbursement guidelines for LA, knowledge about this life-saving therapy is unsatisfactory in medical disciplines treating patients with CVD.

Lipidological competence centres and networks: Future perspectives to improve healthcare of patients with disorders of lipid metabolism.

Background: Numerous healthcare studies have shown that more than 90% of all patients with dyslipidaemia are not treated adequately.

Objectives: The "Deutsche Gesellschaft zur Bekämpfung von Fettstoffwechselstörungen und ihren Folgeerkrankungen (DGFF)" [German Society of Lipidology], a non-profit professional membership organization, has already made a series of efforts to improve the care of patients suffering from dyslipidaemia. A recent outcome is the nationwide implementation and certification of Lipidological Competence Centres and Networks (LCCNs).

Lipoprotein(a)-hyperlipoproteinemia as cause of chronic spinal cord ischemia resulting in progressive myelopathy - successful treatment with lipoprotein apheresis.

High concentrations of lipoprotein(a) (Lp(a)) represent an important independent and causal risk factor associated with adverse outcome in atherosclerotic cardiovascular disease (CVD). Effective Lp(a) lowering drug treatment is not available. Lipoprotein apheresis (LA) has been proven to prevent cardiovascular events in patients with Lp(a)-hyperlipoproteinemia (Lp(a)-HLP) and progressive CVD.

Efficacy, safety, and tolerability of long-term lipoprotein apheresis in patients with LDL- or Lp(a) hyperlipoproteinemia: Findings gathered from more than 36,000 treatments at one center in Germany.

LDL cholesterol (LDL-C) and lipoprotein(a) (Lp(a)) are main risk factors for cardiovascular disease (CVD). Efficacy, safety, and tolerability of lipoprotein apheresis (LA) were investigated in 36,745 LA treatments of 118 patients with CVD in a retrospective, monocentric study. Indications were severe hypercholesterolemia (n = 83) or isolated Lp(a) hyperlipoproteinemia (n = 35).

Clinical benefit of long-term lipoprotein apheresis in patients with severe hypercholesterolemia or Lp(a)-hyperlipoproteinemia with progressive cardiovascular disease.

Low-density lipoprotein cholesterol (LDL-C) and lipoprotein(a) (Lp(a)) are established causal risk factors for cardiovascular disease (CVD). Efficacy, safety, and tolerability of lipoprotein apheresis (LA) were investigated in 118 patients with CVD covering a period with 36,745 LA treatments in a retrospective, monocentric study. Indications for LA were severe hypercholesterolemia (n = 83) or isolated Lp(a) hyperlipoproteinemia (Lp(a)-HLP) (n = 35).

Immunoadsorption in steroid-refractory multiple sclerosis: clinical experience in 60 patients.

Background: Multiple sclerosis (MS) is the most common autoimmune inflammatory demyelinating disease of the central nervous system with a frequently relapsing or progressive course. For steroid-resistant relapse, plasma exchange (PE) has been established as guidelines-recommended treatment option. While PE is a non-selective extracorporeal blood purification process with elimination of plasma and subsequent substitution, immunoadsorption (IA) is a selective technique for the removal of autoantibodies and immune complexes with less adverse effects.

Lipoprotein apheresis standard for apheresis competence centers--an updated synthesis and amendment to pre-existing standards.

With several techniques of selective apheresis treatment, some of which have been established for over 30 years, severe and pharmacologically unmanageable dyslipidemia can be treated successfully. The long-term lowering of LDL cholesterol and lipoprotein(a) by 60-80 percent, together with pleiotropic effects, allow for significant risk reduction in otherwise progressive chronic atherosclerotic disease, i.e.

Characteristics of carotid atherosclerotic plaques of chronic lipid apheresis patients as assessed by in vivo high-resolution CMR--a comparative analysis.

Background: Components of carotid atherosclerotic plaques can reliably be identified and quantified using high resolution in vivo 3-Tesla CMR. It is suspected that lipid apheresis therapy in addition to lowering serum lipid levels also has an influence on development and progression of atherosclerotic plaques. The purpose of this study was to evaluate the influence of chronic lipid apheresis (LA) on the composition of atherosclerotic carotid plaques.

Indication and implementation of lipidapheresis, rheopheresis, or immunoadsorption (lessons learnt from Germany's largest apheresis center).

Efficient modes of extracorporeal blood purification are available today for apheresis treatment of progressive atherosclerosis, autoimmune disease, or for improving hemorheology. Advanced technology and sophisticated care render apheresis treatment selective, safe and tolerable. Our task is to constantly update indications for apheresis based on best evidence available and good clinical practice, as well as, to determine how apheresis therapy can be made available to those in need or with otherwise refractory disease.

Fibrinogen/LDL apheresis as successful second-line treatment of sudden hearing loss: a retrospective study on 217 patients.

Background: Sudden sensorineural hearing loss (SSHL) may be caused by a reduction of cochlear perfusion. Cholesterol and fibrinogen negatively influence rheological properties of blood thus leading to alteration of microcirculation. Fibrinogen/LDL apheresis improves cochlear blood flow by acutely decreasing plasma cholesterol and fibrinogen.
