Effect of Statin Therapy on the Plasma Concentrations of Retinol, Alpha-Tocopherol and Coenzyme Q10 in Children with Familial Hypercholesterolemia.

PURPOSE: Familial hypercholesterolemia (FH) requires early treatment. However, statins, which are regarded the first-line therapy, have an influence on redox balance. Antioxidant vitamins are important for many metabolic processes in the developing body. There are few data available on the long-term safety of statin use in children. The aim of this study was to evaluate the influence of statin treatment in children with FH on plasma concentrations of antioxidant vitamins: retinol, alpha-tocopherol and coenzyme Q10. METHODS: The first study group consisted of 13 children aged 10-18 years treated with simvastatin for at least 6 months, and the second group comprised 13 age- and sex-matched children with hypercholesterolemia, in whom pharmacological treatment had not been applied yet. Analyses were performed using a high-performance liquid chromatograph coupled with a MS detector. RESULTS: The analysis did not reveal significant differences in the concentration of retinol, alpha-tocopherol or coenzyme Q10 between the studied groups. The adjustment of the concentrations of the vitamins to the cholesterol level also indicated no significant differences. We found no deficits in antioxidant vitamins in patients treated with statins, or any risk of adverse effects associated with an increase in their concentration. CONCLUSION: There is no rationale for additional supplementation using antioxidant vitamins or modification of low-fat and low-cholesterol diet in pediatric patients treated with statins.

Berberine and lycopene as alternative or add-on therapy to metformin and statins, a review.

Nutraceuticals are principally extracted from natural products that are frequently safe and well-tolerated. Lycopene and berberine are natural plants with a wide range of beneficial effects including protective activities against metabolic disorders such as diabetes and cardiovascular diseases. These compounds might be considered technically more as a drug than a nutraceutical and could be prescribed as a product. However, further studies are needed to understand if these supplements could affect metabolic syndrome outcomes. Even if nutraceuticals exert a prophylactic activity within the body, their bioactivity and bioavailability have high interindividual variation, and precise assessment of biological function of these bioactive compounds in randomized clinical trials is critical. However, these reports must be interpreted with more considerations due to the low quality of the trials. The aim of this paper is to bring evidence about the management of cardiovascular diseases and diabetes through the use of nutraceuticals with particular attention to lycopene and berberine effectiveness.

Adjuvant Low-dose Statin Use after Radical Prostatectomy: The PRO-STAT Randomized Clinical Trial.

PURPOSE: Statin use is reportedly associated with the risk of prostate cancer, outcomes after treatment, and prostate cancer-specific mortality. We sought to determine the efficacy of adjuvant atorvastatin in prostate cancer after radical prostatectomy. PATIENTS AND METHODS: In this randomized, double-blind trial, we assigned patients with pathologic high-risk prostate cancer to receive either low-dose atorvastatin (20 mg/day, n = 183) or placebo (n = 181) for 1 year after radical prostatectomy. The primary endpoint was the 1-year biochemical recurrence rate. The secondary endpoints included the 5-year biochemical recurrence-free survival and changes in lipid, testosterone, and sex hormone binding globulin levels. RESULTS: From October 2012 through January 2019, a total of 364 patients underwent randomization. Among 59 total primary end points, 30 (16.4%) and 29 (16.0%) occurred in the atorvastatin and placebo groups, respectively. Atorvastatin did not significantly reduce the primary endpoint of 1-year biochemical recurrence [HR, 0.96; 95% confidence interval (CI), 0.58-1.60]. During a median follow-up of 24 months, 131 patients experienced biochemical recurrence (68 in the atorvastatin group and 63 in the placebo group), representing Kaplan-Meier estimated event rates of 24.0% and 25.4% in the atorvastatin and placebo groups, respectively, at 24 months (HR, 1.00; 95% CI, 0.71-1.41). We observed no significant between-group differences in the testosterone and sex hormone binding globulin levels. CONCLUSIONS: Among patients with high-risk pathologic features after radical prostatectomy for prostate cancer, 1-year adjuvant use of atorvastatin was not associated with a lower risk of disease recurrence compared with that for placebo.

In vivo evaluation of combination therapy targeting the isoprenoid biosynthetic pathway.

Geranylgeranyl diphosphate synthase (GGDPS), an enzyme in the isoprenoid biosynthetic pathway (IBP), produces the isoprenoid (geranylgeranyl pyrophosphate, GGPP) used in protein geranylgeranylation reactions. Our prior studies utilizing triazole bisphosphonate-based GGDPS inhibitors (GGSIs) have revealed that these agents represent a novel strategy by which to induce cancer cell death, including multiple myeloma and pancreatic cancer. Statins inhibit the rate-limiting enzyme in the IBP and potentiate the effects of GGSIs in vitro. The in vivo effects of combination therapy with statins and GGSIs have not been determined. Here we evaluated the effects of combining VSW1198, a novel GGSI, with a statin (lovastatin or pravastatin) in CD-1 mice. Twice-weekly dosing with VSW1198 at the previously established maximally tolerated dose in combination with a statin led to hepatotoxicity, while once-weekly VSW1198-based combinations were feasible. No abnormalities in kidney, spleen, brain or skeletal muscle were observed with combination therapy. Combination therapy disrupted protein geranylgeranylation in vivo. Evaluation of hepatic isoprenoid levels revealed decreased GGPP levels in the single drug groups and undetectable GGPP levels in the combination groups. Additional studies with combinations using 50% dose-reductions of either VSW1198 or lovastatin revealed minimal hepatotoxicity with expected on-target effects of diminished GGPP levels and disruption of protein geranylgeranylation. Combination statin/GGSI therapy significantly slowed tumor growth in a myeloma xenograft model. Collectively, these studies are the first to demonstrate that combination IBP inhibitor therapy alters isoprenoid levels and disrupts protein geranylgeranylation in vivo as well as slows tumor growth in a myeloma xenograft model, thus providing the framework for future clinical exploration.

The comparative impact among different intensive statins and combination therapies with niacin/ezetimibe on carotid intima-media thickness: a systematic review, traditional meta-analysis, and network meta-analysis of randomized controlled trials.

PURPOSE: To compare the impact of different statins therapies on the reduction of carotid intima-media thickness (CIMT) may reflect their cardiovascular benefits which is useful in clinical decision. METHODS: PubMed, EMBASE, Cochrane Library, and Web of Science were searched, and 3539 articles published from 1992 to 2020 were retrieved. CIMT in randomized controlled trials for statins therapies were included for traditional and network meta-analyses analyzed by Stata 16. The quality of included studies was assessed by the Cochrane Collaboration's tool. RESULTS: Thirty-three randomized controlled trials (n=8762) were eligible for network meta-analysis, of which 18 randomized controlled trials (n=5252) were included for comparison between statins and no statins and 11 randomized controlled trials (n=1338) were included for comparison between high-intensity statins or combination with niacin/ezetimibe and moderate/low-intensity statins in 2 traditional meta-analyses. In the traditional meta-analyses, the statins groups significantly reduce CIMT compared to no statins (standard mean difference=-0.207, 95% confidence interval: -0.291 to -0.123, p<0.001), while high-intensity statins or combination with niacin/ezetimibe performed significant CIMT reduction compared to moderate/low-intensity statins (standard mean difference=-0.287, 95% confidence interval: -0.460 to -0.114, p=0.001). In the network meta-analysis, a relative rank for the ability to reduce CIMT was given as follows: combination therapy with niacin (mean rank: 1.7), high-intensity statins, combination therapy with ezetimibe, and moderate/low-intensity statins. CONCLUSION: Statins combined with niacin performed a greater CIMT reduction compared to high-intensity statins alone and combination therapies with ezetimibe. The advantage of niacin-combined statins therapies to improve cardiovascular endpoint needs further validation through randomized controlled trials.

Effect of Switching from Low-Dose Simvastatin to High-Dose Atorvastatin on Glucose Homeostasis and Cognitive Function in Type 2 Diabetes.

BACKGROUND: High-intensity statin is recommended in high-risk type 2 diabetes (T2D); however, statin dose dependently increases the risk of developing new-onset diabetes, can potentially worsen glycemic control in T2D, and may cause cognitive impairment. This study aimed to investigate the effect of statin intensification on glucose homeostasis and cognitive function in T2D. MATERIALS AND METHODS: T2D patients who were taking simvastatin ≤20 mg/day were randomized to continue taking the same dosage of simvastatin (low-dose simvastatin group; LS, n=63) for 12 weeks, or to change to atorvastatin 40 mg/day for 6 weeks, and if tolerated, atorvastatin was increased to 80 mg/day for 6 weeks (high-dose atorvastatin group; HS, n=62). Fasting plasma glucose (FPG), glycated hemoglobin (HbA1c), plasma insulin, homeostatic model assessment of insulin resistance (HOMA-IR) and of ß-cell function (HOMA-B), cognitive functions using Montreal Cognitive Assessment (MoCA), and Trail Making Test (TMT) were assessed at baseline, 6 weeks, and 12 weeks. RESULTS: Mean age of patients was 58.8±8.9 years, and 72% were female. Mean baseline FPG and HbA1c were 124.0±27.5 mg/dl and 6.9±0.8%, respectively. No differences in baseline characteristics between groups were observed. Change in HbA1c from baseline in the LS and HS groups was -0.1% and +0.1% (p=0.03) at 6 weeks, and -0.1% and +0.1% (p=0.07) at 12 weeks. There were no significant differences in FPG, fasting plasma insulin, HOMA-B, HOMA-IR, MoCA score, or TMT between groups at 6 or 12 weeks. CONCLUSION: Switching from low-dose simvastatin to high-dose atorvastatin in T2D resulted in a slight increase in HbA1c (0.1%) without causing cognitive decline.

High dose simvastatin and rosuvastatin impair cognitive abilities of healthy rats via decreasing hippocampal neurotrophins and irisin.

BACKGROUND: Statins are cholesterol lowering drugs that decrease the risk of cardiovascular events, but they are related with a few unfavorable symptoms in skeletal muscle including myopathy, and mild to moderate fatigue. Additionally, there has been discrepancies about the impacts of statins on brain and cognition. This study aimed to examine the impacts of two different statins, lipophilic simvastatin and hydrophilic rosuvastatin on cognitive functions in normal healthy rats. Simultaneously, we investigated the alterations of neurotropins and irisin levels in hippocampus and myokine levels in skeletal muscle. METHODS: The rats were dosed with 88 mg kg body weight-1 day-1 simvastatin (n = 8), 150 mg kg body weight-1 day-1 rosuvastatin (n = 8) or vehicle (n = 8) for 18 days via oral gavage. After that behavioral assessment was performed and hippocampus and skeletal muscle samples were taken for the analysis of neurotrophins and irisin levels. RESULTS: Locomotion and learning and memory functions were lower, but anxiety levels were higher in the simvastatin and rosuvastatin groups than in the control group (P < 0.05). Hippocampal neurotrophins and irisin levels were lower, but skeletal muscle brain-derived neurotrophic factor (BDNF) and irisin levels were higher in the simvastatin and rosuvastatin groups than in the control group (P < 0.05). CONCLUSION: These findings suggest that high dose simvastatin and rosuvastatin impair cognitive functions via decreasing BDNF, NGF and irisin levels in the hippocampus.

Recent advances in clinical practice: colorectal cancer chemoprevention in the average-risk population.

Colorectal cancer (CRC) is one of the most common and lethal malignancies in Western countries. Its development is a multistep process that spans more than 15 years, thereby providing an opportunity for prevention and early detection. The high incidence and mortality rates emphasise the need for prevention and screening. Many countries have therefore introduced CRC screening programmes. It is expected, and preliminary evidence in some countries suggests, that this screening effort will decrease CRC-related mortality rates. CRC prevention involves a healthy lifestyle and chemoprevention-more specifically, oral chemoprevention that can interfere with progression from a normal colonic mucosa to adenocarcinoma. This preventive effect is important for individuals with a genetic predisposition, but also in the general population. The ideal chemopreventive agent, or combination of agents, remains unknown, especially when considering safety during long-term use. This review evaluates the evidence across 80 meta-analyses of interventional and observational studies of CRC prevention using medications, vitamins, supplements and dietary factors. This review suggests that the following factors are associated with a decreased incidence of CRC: aspirin, non-steroidal anti-inflammatory drugs, magnesium, folate, a high consumption of fruits and vegetables, fibre and dairy products. An increased incidence of CRC was observed with frequent alcohol or meat consumption. No evidence of a protective effect for tea, coffee, garlic, fish and soy products was found. The level of evidence is moderate for aspirin, ß-carotene and selenium, but is low or very low for all other exposures or interventions.

Chronopharmacology of simvastatin on hyperlipidaemia in high-fat diet-fed obese mice.

The chronopharmacology refers to the utilization of physiological circadian rhythms to optimize the administration time of drugs, thus increasing their efficacy and safety, or reducing adverse effects. Simvastatin is one of the most widely prescribed drugs for the treatment of hypercholesterolaemia, hyperlipidemia and coronary artery disease. There are conflicting statements regarding the timing of simvastatin administration, and convincing experimental evidence remains unavailable. Thus, we aimed to examine whether different administration times would influence the efficacy of simvastatin. High-fat diet-fed mice were treated with simvastatin at zeitgeber time 1 (ZT1) or ZT13, respectively, for nine weeks. Simvastatin showed robust anti-hypercholesterolaemia and anti-hyperlipidemia effects on these obese mice, regardless of administration time. However, simvastatin administrated at ZT13, compared to ZT1, was more functional for decreasing serum levels of total cholesterol, triglycerides, non-esterified free fatty acids and LDL cholesterol, as well as improving liver pathological characteristics. In terms of possible mechanisms, we found that simvastatin did not alter the expression of hepatic circadian clock gene in vivo, although it failed to change the period, phase and amplitude of oscillation patterns in Per2::Luc U2OS and Bmal1::Luc U2OS cells in vitro. In contrast, simvastatin regulated the expression of Hmgcr, Mdr1 and Slco2b1 in a circadian manner, which potentially contributed to the chronopharmacological function of the drug. Taken together, we provide solid evidence to suggest that different administration times affect the lipid-lowering effects of simvastatin.

Circulatory and prostatic tissue lipidomic profiles shifts after high-dose atorvastatin use in men with prostate cancer.

Prostate cancer patients using cholesterol-lowering statins have 30% lower risk of prostate cancer death compared to non-users. The effect is attributed to the inhibition of the mevalonate pathway in prostate cancer cells. Moreover, statin use causes lipoprotein metabolism changes in the serum. Statin effect on serum or intraprostatic lipidome profiles in prostate cancer patients has not been explored. We studied changes in the serum metabolomic and prostatic tissue lipidome after high-dose 80 mg atorvastatin intervention to expose biological mechanisms causing the observed survival benefit. Our randomized, double-blind, placebo-controlled clinical trial consisted of 103 Finnish men with prostate cancer. We observed clear difference in post-intervention serum lipoprotein lipid profiles between the study arms (median classification error 11.7%). The atorvastatin effect on intraprostatic lipid profile was not as clear (median classification error 44.7%), although slightly differing lipid profiles by treatment arm was observed, which became more pronounced in men who used atorvastatin above the median of 27 days (statin group median classification error 27.2%). Atorvastatin lowers lipids important for adaptation for hypoxic microenvironment in the prostate suggesting that prostate cancer cell survival benefit associated with statin use might be mediated by both, local and systemic, lipidomic/metabolomic profile changes.

Association of in-hospital intensive statins dosage and death in arteriosclerotic cardiovascular disease with percutaneous coronary intervention: insights of multicentre cohort from China.

PURPOSE: In-hospital statin dosage-related effect remains unknown for patients with arteriosclerotic cardiovascular disease (ASCVD). This study aimed to determine the associations of different in-hospital intensive statins dosages with the prognosis for patients in the era of percutaneous coronary intervention (PCI). METHODS: From January 2010 to December 2014, consecutive ASCVD patients receiving PCI were enrolled from five centres in China. All the enrolled patients were classified into high-dose (40 mg atorvastatin or 20 mg rosuvastatin) or low-dose (20 mg atorvastatin or 10 mg rosuvastatin) intensive statin group. In-hospital all-cause death was the primary outcome. RESULTS: Of the 7008 patients included in this study, 5248 received low-dose intensive statins (mean age, 64.28 ± 10.39; female, 25.2%), whereas 1760 received high-dose intensive statins (mean age, 63.68 ± 10.59; female, 23.1%). There was no significant difference in the in-hospital all-cause death between the two groups (adjusted OR, 1.27; 95% CI, 0.43-3.72; P = 0.665). All-cause death was similar between the two groups during the 30-day follow-up period (adjusted HR, 1.28; 95% CI, 0.55-2.97; P = 0.571). However, the high-dose intensive statins were tightly associated with the reduction in in-hospital dialysis (adjusted OR, 0.11; 95% CI, 0.01-0.81; P = 0.030). Besides, primary analyses were confirmed by subgroup analyses. CONCLUSIONS: The in-hospital high-dose intensive statins are not associated with the lower risk of in-hospital or 30-day all-cause death among ASCVD patients undergoing PCI. Given the robust beneficial effect of high-dose intensive statins with in-hospital dialysis, an individualized high-dose intensive statin therapy can be rational in specified populations.

Development of a thermosensitive statin loaded chitosan-based hydrogel promoting bone healing.

Statins have been proposed as potential adjuvant to periodontal treatment due to their pleiotropic properties. A new thermosensitive chitosan hydrogel loaded with statins (atorvastatin and lovastatin) nanoemulsions was synthesized to allow a spatially controlled local administration of active compounds at lesion site. Spontaneous nano-emulsification method was used to synthesize statins loaded nanoemulsions. In vitro, atorvastatin and lovastatin loaded nanoemulsions were cytocompatible and were able to be uptake by oral epithelial cells. Treatment of Porphyromonas gingivalis infected oral epithelial cells and gingival fibroblasts with atorvastatin and lovastatin loaded nanoemulsions decreased significantly pro-inflammatory markers expression (TNF-α and IL-1ß) and pro-osteoclastic RANKL. Nevertheless, such treatment induced the expression of Bone sialoprotein 2 (BSP2) in osteoblast emphasizing the pro-healing properties of atorvastatin and lovastatin nanoemulsions. In vivo, in a calvarial bone defect model (2 mm), treatment with the hydrogel loaded with atorvastatin and lovastatin nanoemulsions induced a significant increase of the neobone formation in comparison with systemic administration of statins. This study demonstrates the potential of this statins loaded hydrogel to improve bone regeneration and to decrease soft tissue inflammation. Its use in the specific context of periodontitis management could be considered in the future with a reduced risk of side effects.

Severe statin-induced autoimmune myopathy successfully treated with intravenous immunoglobulin.

Statin-induced autoimmune necrotising myopathy causes a severe progressive muscle weakness even when the statins are discontinued. First-line treatment is usually with high dose steroids followed by immunosuppressants, but this is often ineffective and there is a high risk of side effects. We describe a diabetic patient who had a very severe statin-induced autoimmune myopathy. He made a full recovery with regular intravenous immunoglobulin (IVIg) infusion in relatively low dose (55 g the first day followed by 50 g/day the second and third day, subsequently he was given 50 g/day for 3 days every 6 weeks). His symptoms relapsed when the IVIgs were discontinued for 28 weeks but remitted again following recommencement of IVIg infusions (50 g/day for 3 days every 7 weeks). Our case suggests IVIgs are an effective and well tolerated alternative to steroids and immunosuppressants.

Characterization, Optimization, In Vitro and In Vivo Evaluation of Simvastatin Proliposomes, as a Drug Delivery.

Simvastatin a cholesterol-lowering agent used to treat hypercholesterolemia, coronary heart disease, and dyslipidemia. However, simvastatin (SV) has shown low oral bioavailability in GIT. The main purpose of the work was to develop proliposomal formulations to increase the oral bioavailability of SV. Film deposition on the carrier method has been used to prepare the proliposomes. The proliposomes were assessed for morphology, particulate size, entrapment efficacy, drug-polymer compatibility, in vitro and in vivo studies. FTIR and DSC results revealed no drug-polymer interaction. SEM and XRD analysis conform; proliposomes are spherical, amorphous in nature, so that it enhances the solubility of SV between 15.01 ± 0.026 and 57.80 ± 0.015 µg/mL in pH 7.4 phosphate buffer. The optimised formulation (PL6) shows drug release up to 12 h (99.78 ± 0.067%). The pharmacokinetics of pure SV and SV proliposomes (SVP) in rats were Tmax 2 ± 0.5 and 4 ± 0.7 h, Cmax 10.4 ± 2.921 and 21.18 ± 12.321 µg/mL, AUC0-∞ 67.124 ± 0.23 and 179.75 ± 1.541 µg/mL h, respectively. Optimised SVP shows a significant improvement in the rate and absorption of SV. The optimised formulation showed enhanced oral bioavailability of SV in Albino Wister rats and offers a new technique to improve the poor water-soluble drug absorption in the gastrointestinal system.

Comparison of High-Dose Rosuvastatin Versus Low-Dose Rosuvastatin Plus Ezetimibe on Carotid Atherosclerotic Plaque Inflammation in Patients with Acute Coronary Syndrome.

We compared the effects of ezetimibe/rosuvastatin 10/5 mg versus rosuvastatin 20 mg on carotid atherosclerotic plaque inflammation measured by 18FDG PET/CT. Fifty patients with acute coronary syndrome (ACS) were randomly assigned to the ezetimibe/rosuvastatin 10/5 mg and rosuvastatin 20 mg groups. The primary outcome was the percent change in the target-to-background ratio (TBR) of the index vessel in the most diseased segment (MDS), as assessed by 18FDG PET/CT at baseline and at 6 months. Forty-eight patients completed follow-up PET/CT. MDS TBR was - 6.2 ± 13.9% for patients in the ezetimibe/rosuvastatin group and - 10.8 ± 17.7% for those in the rosuvastatin group (difference, 4.6 percentage points; upper limitation of one-sided confidence interval = 13.8; p = 0.60 for noninferiority). In conclusion, combination therapy with ezetimibe 10 mg and rosuvastatin 5 mg compared with rosuvastatin 20 mg did not meet the criterion for non-inferiority for primary outcome, and the present study was not conclusive on whether the former was non-inferior to the latter. Graphical Abstract.

Reducing Cardiovascular Disease Risk in Women Beyond Statin Therapy: New Insights 2020.

Management of residual and persistent cardiovascular disease (CVD) risk among statin-treated individuals has emerged as an important preventive strategy. The purpose of this article is to review the unique landscape of CVD in women and relevant prior prevention trials, and to discuss how the recent results of the Reduction of Cardiovascular Events with Icosapent Ethyl-Intervention Trial (REDUCE-IT) might apply to the contemporary management of CVD risk among statin-treated women. Women have unique risk factors that may impact CVD and its prevention. Historically, women have been underrepresented in CVD trials, posing a challenge to development of clinical recommendations for women. Low-density lipoprotein cholesterol-targeting treatments have demonstrated CVD risk reduction, with comparable effects in both sexes. In contrast, triglyceride-lowering treatments (niacin, fenofibrate, and omega-3 fatty acids) have reported mixed findings for CVD risk reduction. Recent clinical trials of combination omega-3 fatty acids (docosahexaenoic acid/eicosapentaenoic acid [EPA]) have not found significant CVD risk reduction. The recently published REDUCE-IT study found that icosapent ethyl, an EPA-only omega-3 fatty acid, in combination with statins, significantly reduced CVD events in high-risk patients. The icosapent ethyl group had a significantly lower occurrence of the primary composite CVD endpoint (17.2%) than the placebo group (22.0%; hazard ratio 0.75; 95% confidence interval 0.68-0.83; p < 0.001). CVD risk reduction with icosapent ethyl treatment was comparable between women and men (p for interaction, 0.33). Data from REDUCE-IT suggest women benefit similarly to men with respect to icosapent ethyl, a novel therapy for prevention of CVD.

Impact of Concomitant Medication Administered at the Time of Initiation of Nivolumab Therapy on Outcome in Non-small Cell Lung Cancer.

AIM: To investigate potential association between administration of corticosteroids, antibiotics, probiotics, proton pump inhibitors, non-steroidal anti-inflammatory drugs (NSAID), statins and metformin and outcome in patients with non-small cell lung cancer (NSCLC) treated with nivolumab. PATIENTS AND METHODS: A total of 224 patients with advanced NSCLC treated at nine comprehensive cancer centers were analyzed in this national retrospective study. Survival statistics were evaluated using Kaplan-Meier method and Cox analysis. RESULTS: Only corticosteroid use had a significant negative effect on the objective response rate. In the univariate analysis, there was no significant effect of the studied concomitant medications on the efficacy of nivolumab. In a subsequent multifactorial analysis, a possible positive effect of the concomitant use of NSAID at the initiation of nivolumab treatment was revealed. CONCLUSION: The results of the present retrospective exploratory analysis underscore the importance of knowing the exact type of concomitant medication, the route of administration, the dose of medication, and the region of the ongoing study. The present data indicated a significantly higher rate of progression in patients treated with corticosteroids and the possible positive effect of NSAID use at the initiation of nivolumab treatment.

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.

Utilisation and maintenance of high-intensity statins following acute coronary syndrome and coronary angiography: opportunities to improve care (ANZACS-QI 26).

AIMS: A key pillar in the medical management of patients after an acute coronary syndrome (ACS) is the early initiation and maintenance of "high-intensity" statin therapy to lower low-density lipoprotein cholesterol (LDL-C) and to improve clinical outcomes. The aim of this study was to describe the New Zealand utilisation of high-intensity statin therapy in the first year post-ACS. METHODS: 19,867 New Zealand patients (≥20 years), discharged post-ACS event (2015-2017) were identified from the All New Zealand ACS Quality Improvement (ANZACS-QI) registry and anonymously linked with the national pharmaceutical dataset to identify statin dispensing early (0-3 months) and late (9-12 months) post-discharge. "High intensity" statin was subdivided into the New Zealand guidelines recommended dose (80mg atorvastatin) and "other high-intensity" statin (atorvastatin 40mg, simvastatin 80mg). All other statin doses were classified as "low/medium dose". RESULTS: Seventy-nine percent were initially dispensed high-intensity statins. Thirty-six percent of the overall cohort received 80mg atorvastatin and 43% a lower "other high-intensity" statin. A further 13% received a medium/low dose and 8% no statin. By 12 months, 29% were dispensed atorvastatin 80mg, 36% another high dose, 14% a low/medium dose and 21% no statin. Only 14% of those initially on 80mg atorvastatin had a statin dose reduction. After multivariable adjustment, the risk of discontinuation was the same for those started on atorvastatin 80mg compared with "other high dose", and lower than for those started on a low/medium dose. Few patients (6.2%) had statins started, or dose up-titrated post-discharge. There is clinically unexplained variation in the use of the highest atorvastatin 80mg dose between district health boards (range 15% to 65%). CONCLUSIONS: Eight in 10 ACS patients were dispensed a high-intensity statin at discharge, but only 36% received the guidelines-recommended dose of 80mg of atorvastatin. By one year, one in five patients discharged on a statin were not receiving it. There are opportunities to improve longer-term LDL-C reduction and clinical outcomes through dosage optimisation and improved medication maintenance.

Optimal high-density lipoprotein cholesterol level for decreasing benign prostatic hyperplasia in men not taking statin medication: A historical cohort study.

BACKGROUND: We evaluated the optimal high-density lipoprotein cholesterol level for benign prostatic hyperplasia (BPH) prevention in men not taking statin medication using a large historical cohort. METHODS: We initially selected 130 454 men who underwent health checkups in 2009 from the National Health Information Database of the National Health Insurance Service. After excluding 36 854 men with BPH in 2009, and 45 061 men for statin use, 48 539 men were ultimately included in the analysis. A Kaplan-Meier analysis and multivariable Cox regression analysis was performed to assess the optimal high-density lipoprotein cholesterol level for preventing BPH. RESULTS: High-density lipoprotein cholesterol levels were less than 40 mg/dL in 7431 (15.3%) men, 40 to 49 in 15 861 (32.7%), 50 to 59 in 15 328 (27.5%), and greater than or equal to 60 in 11 919 (24.6%). The overall cumulative incidence of BPH was 4.4%, 8.7%, 13.0%, and 17.8% at the 1-, 2-, 3-, and 4-year follow-up periods, respectively. In multivariable analysis, high-density lipoprotein greater than or equal to 60 mg/dL were significantly associated with a decreased incidence of BPH, as were age, residence, income, body mass index, diabetes, hypertension, triglyceride, and increased annual clinic visits, especially in men in their 40s. CONCLUSION: Elevated serum high-density lipoprotein cholesterol levels were negatively associated with BPH incidence. In addition, maintaining high-density lipoprotein greater than or equal to 60 mg/dL was associated with a decreased BPH incidence compared with high-density lipoprotein less than 40 mg/dL, especially in men in their 40s.
