BackgroundIn contrast to guidelines related to lipid therapy in other areas, 2012 Kidney Disease Improving Global Outcomes (KDIGO) guidelines recommend conducting a lipid profile upon diagnosis of chronic kidney disease (CKD) and treating all patients older than 50 years without defining a target for lipid levels. We evaluated multinational practice patterns for lipid management in patients with advanced CKD under nephrology care.MethodsWe analyzed lipid-lowering therapy (LLT), LDL- cholesterol (LDL-C) levels, and nephrologist-specified LDL-C goal upper limits in adult patients with eGFR < 60 ml/min from nephrology clinics in Brazil, France, Germany, and the United States (2014–2019). Models were adjusted for CKD stage, country, cardiovascular risk indicators, sex, and age.ResultsLLT treatment differed significantly by country, from 51% in Germany to 61% in the US and France (p= 0.002) for statin monotherapy. For ezetimibe with or without statins, the prevalence was 0.3% in Brazil to 9% in France (< 0.001). Compared with patients not taking lipid-lowering therapy, LDL-C was lower among treated patients (p< 0.0001) and differed significantly by country (p< 0.0001). At the patient level, the LDL-C levels and statin prescription did not vary significantly by CKD stage (p= 0.09 LDL-C andp= 0.24 statin use). Between 7—23% of untreated patients in each country had LDL-C ≥ 160 mg/dL. Only 7–17% of nephrologists believed that LDL-C should be < 70 mg/dL.ConclusionThere is substantial variation in practice patterns regarding LLT across countries but not across CKD stages. Treated patients appear to benefit from LDL-C lowering, yet a significant proportion of hyperlipidemia patients under nephrologist care are not receiving treatment.Supplementary InformationThe online version contains supplementary material available at 10.1186/s12944-023-01833-z.
