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. In 2011 the German Lipoprotein Apheresis Registry (GLAR) was launched and data acquired over nearly 5 years can now be reported. Methods and results: All data were collected and analyzed during the time period 2012–2015. Over this time interval, 68 German apheresis centers collected retrospective and prospective observational data of 1.283 patients undergoing lipoprotein apheresis (LA) treatment of high LDL-cholesterol (LDL-C) levels and/or high lipoprotein(a) (Lp(a)) levels suffering from progressive cardiovascular disease (CVD). A total of 15,167 documented LA treatments were investigated. All patients treated by LA exhibited a median LDL-C reduction rate of 68.6%, and a median Lp(a) reduction rate of 70.4%. Analogue to the Pro(a)LiFe pattern, patient data were analyzed and compared with respect to the incidence rate of coronary events (MACE) 1 and 2 years before the start of LA treatment (y−2 and y−1) and prospectively one year on LA treatment (y+1). During the first year of LA treatment a MACE reduction of 97% was be observed. In the years considered, LA treatment side effects occurred at a low rate (ca. 5%) and mainly comprised puncture problems. Conclusions: For the first time data generated by the GLAR shows that LA lowers the incidence rate of cardiovascular events in patients with high LDL-C and/or high Lp(a) levels, progressive CVD and maximally tolerated lipid lowering medication. In addition LA treatments were found to be safe, exhibiting a low rate of side effects

Novel insights into the management of patients with very high cardiovascular risk eligible for PCSK9 inhibitor treatment: Baseline findings from the PERI-DYS study.

AIM: The PERI-DYS study aims to characterize two groups of patients with dyslipidaemia at very high CV risk: PCSK9i receivers and patients qualifying for but not receiving PCSK9i. METHODS: This is an observational study by office-based and clinic-based physicians, mainly cardiologists and other internists in Germany, with data extracted from patient charts. CLINICALTRIALS: gov identifier NCT03110432. RESULTS: A total of 1659 patients were enrolled across 70 sites. The majority of patients (91.0%) were reported as having mixed dyslipidaemia or non-familial or heterozygous familial hypercholesterolemia. At enrolment, 794 (47.9%) of patients were PCSK9i receivers (of these 65.9% ongoing, and 34.1% newly treated within 30 days before their baseline visit). Among PCSK9i receivers, the majority had evolocumab 140 mg (n = 632, 38.1% of total). PCSK9i receivers compared to non-receivers were about 2 years younger and had a lower proportion of males. In terms of comorbidities, they had (statistically significantly) more often CAD, and less often PAD, diabetes mellitus, arterial hypertension and chronic renal disease. The calculated untreated median LDL-C was 187 mg/dl (IQR 127; 270) in ongoing PCSK9i receivers, 212 mg/dl (IQR 132; 277) in newly treated PCSK9i receivers, and 179 mg/dl (IQR 129; 257) in non-receivers. Physician-reported statin intolerance was much more common in the two PCSK9i receiver groups as compared to non-receivers (67.3% versus 15.3%). Consequently, patients in the PCSK9i groups received fewer concomitant statins. Mean total cholesterol (143 vs. 172 mg/dl) and LDL-C (69 vs. 99 mg/dl) were considerably lower in ongoing PCSK9i receivers compared to non-receivers. CONCLUSIONS: PCSK9i receivers are characterized by higher baseline LDL-C and a higher portion of statin intolerance compared to those qualified for but not-receiving PCSK9i treatment. On-treatment, LDL-C was lower in PCSK9i receivers. Ongoing follow-up will determine the prognostic importance of these findings
