The German Lipoprotein Apheresis Registry-Summary of the ninth annual report.

During 2012-2020, 89 German apheresis centers collected retrospective and prospective observational data of 2028 patients undergoing regular lipoprotein apheresis (LA) for the German Lipoprotein Apheresis Registry (GLAR). More than 47 500 LA sessions are documented in GLAR. In 2020, all patients treated with LA showed a high immediate median reduction rate of LDL-C (68.

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.

Lipoprotein(a) - Marker for cardiovascular risk and target for lipoprotein apheresis.

Lipoprotein(a) (Lp(a)) consists of an LDL particle whose apolipoprotein B (apoB) is covalently bound to apolipoprotein(a) (apo[a]). An increased Lp(a) concentration is a causal, independent risk factor for atherosclerotic cardiovascular disease (ASCVD) and a predictor of incident or recurrent cardiovascular events. Although Lp(a) was first described as early as 1963, only the more recent results of epidemiological, molecular, and genetic studies have led to this unequivocal conclusion.

Lipoprotein apheresis is an optimal therapeutic option to reduce increased Lp(a) levels.

Lipoprotein(a) (Lp(a)) is a genetic risk factor for cardiovascular disease (CVD) and is associated with the induction and sustaining of atherosclerotic cardiovascular diseases (ASCVD). Since 2008 Lp(a) along with progressive CVD has been approved as an indication for regular lipoprotein apheresis (LA) in Germany. The German Lipoprotein Apheresis Registry (GLAR) has been initiated to provide statistical evidence for the assessment of extracorporeal procedures to treat dyslipidemia for both LDL-cholesterol (LDL-C) and Lp(a).

Current insights into the German Lipoprotein Apheresis Registry (GLAR) - Almost 5 years on.

Background: In recent years the Federal Joint Committee (G-BA), a paramount decision-making body of the German health care system required a reassessment of the approval of chronic lipoprotein apheresis therapy for regular reimbursement. Since 2005 an interdisciplinary German apheresis working group has been established by members of both German Societies of Nephrology. In 2009 the working group completed the indication for lipoprotein apheresis with respect to current cardiovascular guidelines and current scientific knowledge for the registry.

The German Lipoprotein Apheresis Registry (GLAR) - almost 5 years on.

Background: Since 2005 an interdisciplinary German apheresis working group has been established by members of both German Societies of Nephrology and of Lipidologists and completed the data set for the registry according to the current guidelines and the German indication guideline for apheresis in 2009. In 2011 the German Lipoprotein Apheresis Registry (GLAR) was launched and data are available over nearly 5 years now.

Methods And Results: During the time period 2012-2016, 71 German apheresis centers collected retrospective and prospective observational data of 1435 patients undergoing lipoprotein apheresis (LA) treatment of high LDL-C levels and/or high Lp (a) levels suffering from cardiovascular disease (CVD) or progressive CVD.

Lipoprotein Apheresis for Lipoprotein(a)-Associated Cardiovascular Disease: Prospective 5 Years of Follow-Up and Apolipoprotein(a) Characterization.

Objective: Lipoprotein(a)-hyperlipoproteinemia (Lp(a)-HLP) along with progressive cardiovascular disease has been approved as indication for regular lipoprotein apheresis (LA) in Germany since 2008. We aimed to study the long-term preventive effect of LA and to assess hypothetical clinical correlations of apolipoprotein(a) (apo(a)) by analyzing genotypes and phenotypes.

Approach And Results: This prospective observational multicenter study included 170 patients with Lp(a)-HLP and progressive cardiovascular disease (48.

First data from the German Lipoprotein Apheresis Registry (GLAR).

Objective: In recent years the Federal Joint Committee (G-BA), a paramount decision-making body of the German health care system challenged the approval of diagnostic and therapeutic procedures for regular reimbursement, including lipoprotein apheresis therapy. Years before an interdisciplinary German apheresis working group, established by members of both German Societies of Nephrology (Verband Deutsche Nierenzentren (VDN), Deutsche Gesellschaft für Nephrologie (DGfN)), initiated a revision of the indication of lipoprotein apheresis therapy according to current guidelines and recommendations for the treatment of lipid disorders. This working group was convinced, that data derived from a registry would support lipoprotein apheresis as a therapy for severe hyperlipidemic patients suffering from progressive cardiovascular diseases.

Impact of the German Lipoprotein Apheresis Registry (DLAR) on therapeutic options to reduce increased Lp(a) levels.

Background: The German Lipoprotein Apheresis Registry (DLAR) has been initiated by members of the Nephrology Foundation (WiNe), the German association of kidney centres (DN), the German society of nephrology (DGfN) and additional medical associations taking part in the apheresis working group. Its goal is the introduction of a substantial database, suitable to provide statistical evidence for the assessment of extracorporeal procedures. Data have been added to the DLAR since October 2011.

Lipoprotein apheresis in patients with maximally tolerated lipid-lowering therapy, lipoprotein(a)-hyperlipoproteinemia, and progressive cardiovascular disease: prospective observational multicenter study.

Background: Lipoprotein(a) (Lp(a)) hyperlipoproteinemia is a major risk factor for cardiovascular disease, which is not affected by treatment of other cardiovascular risk factors. This study sought to assess the effect of chronic lipoprotein apheresis (LA) on the incidence of cardiovascular events in patients with progressive cardiovascular disease receiving maximally tolerated lipid-lowering treatment.

Methods And Results: In a prospective observational multicenter study, 170 patients were investigated who commenced LA because of Lp(a)-hyperlipoproteinemia and progressive cardiovascular disease.

Longitudinal cohort study on the effectiveness of lipid apheresis treatment to reduce high lipoprotein(a) levels and prevent major adverse coronary events.

Background: We investigated in a longitudinal, multicenter, cohort study whether combined lipid apheresis and lipid-lowering medication can reduce extremely high levels of lipoprotein(a) (Lp[a]) and thus prevent major adverse coronary events (MACE) more efficaciously than lipid-lowering medication alone.

Methods: Eligible patients had coronary artery disease and Lp(a) levels > or =2.14 micromol/l (95th percentile).

Therapeutic plasmapheresis and haemostatic system.

The influence of therapeutic plasmapheresis by using membrane filter was investigated in 38 patients with 108 procedures. Fibrinogen and AT III reached most pronounced reduced levels in the course of three plasma exchanges while factors II, V, X, Hepato-Quick, Reptilase time and thrombocyte count remained relatively unchanged. There was no bleeding or thrombotic event in the patients.
