Statin toxicity – updated review
Statin prescribers and statin skeptics get into heated debates regarding risks and benefits for this class of cholesterol-lowering drugs. Benefits of statins have been reviewed extensively and their use in patients at high CVD risk is and remains firmly established. Managing patients in whom statin is indicated, awareness and knowledge of statin-related adverse effects is essential. The authors of this article provide broad and in-depth insights about the potential risks and harms of statin therapy as well as practical pointers on how to deal with most commonly reported side effects. It includes a review of the mechanisms of action, including pharmacokinetics and dynamics of the different statins. Statin-associated muscle symptoms (SAMS) are explored extensively and provides a better understanding of the possible causes and different types of SAMS, including clinical presentations. Prevalence and risk factors for developing SAMS as well as intrinsic mechanisms that are considered to elicit the symptoms of pain and muscle cramps are explained. Metabolic changes triggered by statins, cellular and subcellular, e.g. mitochondrial toxicity and calcium channel signaling are discussed. Pharmacogenetic targets, such as SLCO1B1 gene, new onset type 2 diabetes, neurological neurocognitive (including dementia and Alzheimer disease), hepatoxicity, renal toxicity and of target statin side effects are appraised as well. The article is “open access”, a free article that provides interested health care providers not only with an elaborate 23-page statin toxicity review but allow those that are exploring specific topics to do so by assessing 195 referenced publications as well.

The potential side effects of long term PCSK9ab use
The latest addition to our LDL-c lowering armamentarium, the PCSK9ab have proven to be not only highly efficacious but safe and very well tolerated as well. The limited clinical experience spanning ± 5 years provides limited re-assurance on long term safety. One well-recognized statin side-effect, new onset diabetes (NODM), has not surfaced in the two largest PCSK9ab clinical trials the ODYSSEY Outcome and FOURIER studies. The authors of this article explored the effects of a genetic variant (T allele of rs1159147), in the PCSK9 gene, associated with a loss of function phenotype. Using data collected in 479 522 participants of the UK Biobank, they observed an association with T2DM, increased body mass index, waist circumference, waist-hip ratio, diastolic blood pressure, type 1 diabetes mellitus, and insulin use. The association of the PCSK9 T allele with T2DM was independent of BMI and central obesity, this contrasted with diastolic blood pressure where this association remained robust. The T allele was also associated with peptic ulcer disease, depression, asthma, chronic kidney disease, and venous thromboembolism. Based on these observations, long term use of PCSK9ab could be associated with NODM, similar like statins, and alertness for other potential side effects in patients that use PCSK9ab for a prolonged period of time, such as (young) FH patients, is warranted.

Fish-oils what is there to know?
Managing LDL-c plasma levels with statins and add on LDL-c lowering drugs such as ezetimibe and PCSK9ab has proven to be unequivocally successful. Despite reaching very low LDL-c levels a significant number of patients continue to experience CV complications. From this perspective addressing the residual risk is gaining importance in managing patients prone to ASCVD. In this review, the potential benefits of using omega-3 fatty acids as an add-on to statins in high risk (hypertriglyceridemic) patients are discussed. Despite the failure of earlier trials in establishing benefits of fish oils, the recent REDUCE-IT trial, using eicosapentaenoic acid (EPA) in a high dose (4 gr/day) was associated with an impressive 25% reduction of CV-events in patients with CVD or DM2. In this updated review the mechanisms of action beyond TG lowering are highlighted, improving endothelial function, reducing oxidative stress of various ApoB-containing lipoprotein particles, increasing the functionality of HDL, inhibiting inflammation & plaque as well as stabilizing plaques. An intriguing mechanism, suggested as unique for EPA, is the inhibition of glucose-induced cholesterol crystalline domain formation as to preserve normal membrane structure, lipid organization as well as membrane lipid oxidation. These properties are not observed with docosahexaenoic acid (DHA) or other TG lowering drugs. The author suggests that certain benefits are markedly enhanced when EPA is combined with statins. The three large still ongoing trials will help increase the understanding of the role of Omega-3 fatty acids in managing residual risk in statin-treated patients. Positive outcomes would establish the use of EPA and/or DHA as a valuable add on therapy in patients that use statins to lower their (residual) CVD risk.

Reduced mortality when starting statins before dialysis
In dialysis patients starting statin are not recommended based on the negative results of two large clinical outcome trials. Guidelines do advice to continue statins when started before dialysis. In this retrospective analysis of US veterans (2007 – 2014) effects of continuing statins initiated > 12 months before starting dialysis and survived at least 1 year of dialysis. The primary outcome 12-month all-cause mortality and CV mortality. Mean age 71 (SD:10) years majority were male (96.7%), African American (21.3%). Diabetes was diagnosed in 74.6% of the participants. After 1-year statin use was associated with lower all-cause and CV mortality. Reported deaths per 100 person-years were 21.9 (20.9-22.8) and 8.1 (7.5-8.6) in statin continuers vs 30.3 (27.8-32.8) and 9.8 (8.3-11.2) in statin discontinuers. After adjusted Cox proportional hazard regression analysis, the benefits in statin users persisted and resulted in an HR of 0.72 (0.66-0.79) and 0.82 (0.69-0.96) respectively. When corrected for age, race and diabetes status results remained the same. The authors suggested that based on the observed rapid and significant benefits of pre-dialysis statin use in ultimately dialysis-dependent patients, future studies are needed to confirm the observed benefits.

CVD outcomes relate to statin intensity + adherence in a large UK primary care cohort
Observational analysis of large National registries can provide important and relevant insights on the effects of CVD preventive disease management strategies. To evaluate the effects of statin adherence as well as statin intensity on clinical outcomes the authors used the UK primary cared Clinical Practice Research Datalink from January 2010 through February 2016. Three groups of patients were selected: Patients with CVD, patients with DM2 and no CVD or chronic kidney disease (CKD) and patients with CKD but no CVD. Included were patients that started with statins and/or ezetimibe between 2010 – 2013 and had prescriptions during the following year. Statin intensity was defined as low intensity (< 30% LDL-c lowering), moderate intensity (30-50% LDL-c lowering) and high intensity (>50% LDL-c Lowering). Patients were considered adherent if >80% of the statins were used. Endpoints Composite endpoint of cardiovascular death or hospitalization for myocardial infarction, unstable angina, ischemic stroke, heart failure, or revascularization. Hazard ratios were estimated by comparing the adherent patient to patients that did not continue their statin regimen. Evaluated were 29 797 newly treated patients; there were 16 701, 12 422, and 674 patients with documented CVD, type 2 diabetes without CVD or CKD, and CKD without CVD, respectively. Patients with CVD were more likely to be Adherent if they used high-intensity statins; 84.1%in year 1 and 72.3%in year 6. In patients receiving low-intensity therapy, 57.4% were adherent in year 1 and 48.4% in year 6. Combining the parameters of adherence and statin intensity showed a graded relationship with % LDL-c decrease and CVD outcomes. For each 10% upturn of the combined grade was associated with a 10% lower CVD risk, HR: 0.90 (0.86-0.94). The best outcomes were seen in patients that used high-intensity statin and were adherent for 1 year or longer, HR: 0.60 (0.54-0.68) compared to patients that were not treated for 1 year or longer. The results were congruent in diabetics, HR: 0.67 (0.57-0.79) and CKD patients, HR: 0.39 (0.25-0.61). Noteworthy was that patients treated with high-intensity statins vs low-intensity statins had similar adherence rates. These results prioritize the use of high-intensity statins in patients at risk for CVD complications, even in a primary prevention setting! Strategies to ensure adherence as well as promoting high-intensity statins prescriptions need to be prioritized if we want to succeed in optimally reducing CVD risk.
