Opinions of nephrologists on the efficacy and tolerance of statins in hemodialysis patients

Evaluation of Statin Use and Prescribing in Patients with Chronic Kidney Disease Not Receiving Treatment with Kidney Transplant or Dialysis

Background

Chronic kidney disease (CKD) is a risk factor for cardiovascular disease. The Kidney Disease Improving Global Outcomes 2013 guidelines and the Canadian Cardiovascular Society 2016 guidelines recommend statins for primary prevention of cardiovascular disease in CKD patients aged 50 years or older who are not receiving treatment with kidney transplant or dialysis.

Objectives

To evaluate statin use for patients in the Vancouver General Hospital Kidney Care Clinic (VGH KCC) and to gain insight into the KCC nephrologists' practices and perspectives regarding the prescribing of statins for patients with CKD.

Methods

The study comprised 2 parts. Part 1 consisted of a cross-sectional study of all statin-eligible patients in the VGH KCC followed by a retrospective chart review. In the chart review, data were collected for 250 statin users and 250 non-users. Logistic regression analyses were performed to determine associations between demographic variables and statin use or non-use. Part 2 was an electronic survey of VGH KCC nephrologists.

Results

Of the 813 statin-eligible patients, 512 (63%) were taking a statin. Patients were approximately 5 times more likely to be receiving statin therapy when it was indicated for secondary versus primary prevention (adjusted odds ratio 4.64, 95% confidence interval 2.95-7.47). Eight of the 9 KCC nephrologists completed the survey, and 7 (87.5%) of these respondents indicated that they never or rarely prescribed statins themselves to KCC patients for primary prevention. However, the same number reported that they sometimes or often suggested statin initiation to family physicians. Three of the respondents indicated agreement with guideline recommendations, but many stated that the decision for statin initiation should be individualized to the patient. Strategies to improve statin prescribing rates that were endorsed by respondents included educating family physicians, creating preprinted orders and laboratory requisitions for statin initiation, providing educational materials about statins to patients, and implementing a protocol for KCC pharmacists to counsel patients about statins.

Conclusions

Many statin-eligible VGH KCC patients were not receiving statin therapy, and most of the KCC nephrologists considered statin prescribing as a role for family physicians. Within the KCC, future directions will be to develop a standardized approach to identify patients who would benefit from statin therapy, and to implement strategies to improve statin prescribing rates in appropriate patients.

Emperor's syndrome in the COVID-19 era: Time for patient-centered nephrology?

The coronavirus disease-19 (COVID-19) pandemic has been a wake-up call in which has forced us to react worldwide. Health policies and practices have attracted particular attention in terms of human and financial cost. Before COVID-19, chronic kidney disease was already considered a risk multiplier in patients with diabetes and hypertension, the two now being the major risk factors for COVID-19 infection and adverse outcome. In contrast to the urgent need for action, the nephrology field is considered to be in a state of stagnation regarding the management of chronic kidney disease patients who still experience unacceptably high morbidity and mortality. Ironically and paradoxically in a field lacking robust clinical trials, clinical practice is driven by guidelines-based medicine on weak evidence. The Emperor's syndrome, referring to Hans Christian Andersen's fairy tale, has been described in medicine as voluntary blindness to an obvious truth, being a weak evidence-based therapeutic intervention or weak health care. A promising positive example of improving heart and kidney outcomes is the emerging treatment with sodium-glucose cotransporter 2 inhibitors. COVID-19 could boost actions for patient-centered care as a positive shift in nephrology care.

An overview of statin-induced myopathy and perspectives for the future

Introduction: Statins remain the most commonly prescribed lipid-lowering drug class for the treatment of atherosclerotic cardiovascular disease. Their well-recognized side effects are known as statin-associated muscle symptom (SAMS). Some advances in this field have been made in recent years, but the understanding of the mechanisms has lagged. Investigating the specific role of the anti-HMGCR autoantibody, pharmacokinetic genetic variants, characterization of the known phenotypes of statin toxicity, in relation to clinical markers of disease, is of high importance.Areas covered: We summarized currently available findings (on PubMed) related to SAMS and discussed the therapeutic approaches, risk factors, drug interactions, potential novel systems, algorithms and biomarkers for SAMS detection. CoQ10 supplementation has been suggested as a complementary approach to manage SAMS, while vitamin D levels may be useful for both the diagnosis and management.Expert Opinion/Commentary: Further studies might help to understand the easiest way to diagnose SAMS, suitable prevention and an effective non-statin therapy. This review sheds new light on the future directions in both research and clinical practice, which will help with rapid risk assessment, identification of the SAMS risk factors in order to decrease the incidence of statins' adverse effects, and the most effective therapy.

Trends in Statin Use Among US Adults With Chronic Kidney Disease, 1999-2014

Background The 2013 American College of Cardiology/American Heart Association cholesterol guidelines recognize cardiovascular disease and diabetes mellitus but not chronic kidney disease ( CKD ) as high-risk conditions warranting statin therapy. Statin use may be lower for adults with CKD compared with adults with conditions that have guideline indications for statin use. Methods and Results We analyzed data from the National Health and Nutrition Examination Surveys from 1999-2002 through 2011-2014 to determine trends in the percentage of US adults ≥20 years of age with and without CKD taking statins. CKD was defined by an estimated glomerular filtration rate <60 mL/min per 1.73m2 or albumin-to-creatinine ratio ≥30 mg/g. Statin use was identified through a medication inventory. Between 1999-2002 and 2011-2014, the percentage of adults taking statins increased from 17.6% to 35.7% among those with CKD and from 6.8% to 14.7% among those without CKD . After multivariable adjustment, adults with CKD were not more likely to be taking statins compared with those without CKD (prevalence ratio, 1.01; 95% CI] 0.96-1.08). Among adults without a history of cardiovascular disease, those with CKD but not diabetes mellitus were less likely to be taking statins compared with those with diabetes mellitus but not CKD (prevalence ratio, 0.54; 95% CI , 0.44-0.66). Among adults with a history of cardiovascular disease, there was no difference in statin use between those with CKD but not diabetes mellitus versus those with diabetes mellitus but not CKD (prevalence ratio, 0.95; 95% CI , 0.79-1.15). Conclusions CKD does not appear to be a major stimulus for statin use among US adults.
