Abstract
OBJECTIVE Statin treatment reduces the risk of atherosclerotic cardiovascular disease but is associated with a modest increased risk of type 2 diabetes, especially in those with insulin resistance or prediabetes. Our objective was to determine the physiological mechanism for the increased type 2 diabetes risk. APPROACH AND RESULTS We conducted an open-label clinical trial of atorvastatin 40 mg daily in adults without known atherosclerotic cardiovascular disease or type 2 diabetes at baseline. The co-primary outcomes were changes at 10 weeks versus baseline in insulin resistance as assessed by steady-state plasma glucose during the insulin suppression test and insulin secretion as assessed by insulin secretion rate area under the curve (ISRAUC) during the graded-glucose infusion test. Secondary outcomes included glucose and insulin, both fasting and during oral glucose tolerance test. Of 75 participants who enrolled, 71 completed the study (median age 61 years, 37% women, 65% non-Hispanic White, median body mass index, 27.8 kg/m2). Atorvastatin reduced LDL (low-density lipoprotein)-cholesterol (median decrease 53%, P<0.001) but did not change body weight. Compared with baseline, atorvastatin increased insulin resistance (steady-state plasma glucose) by a median of 8% (P=0.01) and insulin secretion (ISRAUC) by a median of 9% (P<0.001). There were small increases in oral glucose tolerance test glucoseAUC (median increase, 0.05%; P=0.03) and fasting insulin (median increase, 7%; P=0.01). CONCLUSIONS In individuals without type 2 diabetes, high-intensity atorvastatin for 10 weeks increases insulin resistance and insulin secretion. Over time, the risk of new-onset diabetes with statin use may increase in individuals who become more insulin resistant but are unable to maintain compensatory increases in insulin secretion.

Abstract
BACKGROUND Although accumulating evidence suggests a more extensive reduction of low-density lipoprotein cholesterol (LDL-C), it is unclear whether a higher statin dose is more effective and cost-effective in the Asian population. This study compared the efficacy, safety, and cost-effectiveness of atorvastatin 20 and 10 mg in high-risk Asian patients with hypercholesterolemia. METHODS A 12-week, open-label, parallel, multicenter, Phase IV randomized controlled trial was conducted at ten hospitals in the Republic of Korea between October 2017 and May 2019. High-risk patients with hypercholesterolemia, defined according to 2015 Korean guidelines for dyslipidemia management, were eligible to participate. We randomly assigned 250 patients at risk of atherosclerotic cardiovascular disease to receive 20 mg (n = 124) or 10 mg (n = 126) of atorvastatin. The primary endpoint was the difference in the mean percentage change in LDL-C levels from baseline after 12 weeks. Cost-effectiveness was measured as an exploratory endpoint. RESULTS LDL-C levels were reduced more significantly by atorvastatin 20 mg than by 10 mg after 12 weeks (42.4% vs. 33.5%, p < 0.0001). Significantly more patients achieved target LDL-C levels (<100 mg/dL for high-risk patients, <70 mg/dL for very high-risk patients) with atorvastatin 20 mg than with 10 mg (40.3% vs. 25.6%, p < 0.05). Apolipoprotein B decreased significantly with atorvastatin 20mg versus 10 mg (-36.2% vs. -29.9%, p < 0.05). Lipid ratios also showed greater improvement with atorvastatin 20 mg than with 10 mg (total cholesterol/high-density lipoprotein cholesterol ratio, -33.3% vs. -29.4%, p < 0.05; apolipoprotein B/apolipoprotein A1 ratio, -36.7% vs. -31.4%, p < 0.05). Atorvastatin 20 mg was more cost-effective than atorvastatin 10 mg in terms of both the average and incremental cost-effectiveness ratios. Safety and tolerability of atorvastatin 20 mg were comparable to those of atorvastatin 10 mg. CONCLUSION In high-risk Asian patients with hypercholesterolemia, atorvastatin 20 mg was both efficacious in reducing LDL-C and cost-effective compared with atorvastatin 10 mg.

Abstract
This phase 1, 2-part, 2-period, open-label, drug-drug interaction study evaluated the potential for pharmacokinetic interactions between upadacitinib and rosuvastatin, an organic anion transporting polypeptide (OATP) 1B1 and breast cancer resistance protein substrate, or atorvastatin, a cytochrome P450 3A, OATP1B1, and OATP1B3 substrate, in 36 healthy volunteers. During period 1, a single dose of rosuvastatin (5 mg; part 1) or atorvastatin (10 mg; part 2) was administered on day 1, followed by a washout period of 5 days. During period 2, once-daily doses of upadacitinib extended-release (30 mg) were administered on days 1 to 10, and a single dose of rosuvastatin (5 mg; part 1) or atorvastatin (10 mg; part 2) was administered 1 hour after the upadacitinib dose on day 7. Serial blood samples were collected for assays of drug concentrations. In Part 1, rosuvastatin maximum observed plasma concentration (Cmax ) and area under the plasma concentration-time curve from time 0 to infinity (AUCinf ) were 23% and 33% lower, respectively, when administered with upadacitinib relative to when administered alone. In part 2, atorvastatin Cmax and AUCinf was 11% and 23% lower, respectively, when administered with upadacitinib relative to when administered alone. The Cmax and AUCinf of the active metabolite ortho-hydroxyatorvastatin remained unchanged. Administration of a single 5-mg dose of rosuvastatin or a single 10-mg dose of atorvastatin had no relevant effect on upadacitinib Cmax or area under the plasma concentration-time curve. These results demonstrated that upadacitinib has no clinically relevant effect on the pharmacokinetics of rosuvastatin and atorvastatin or on substrates transported by OATP1B or breast cancer resistance protein.

Abstract
BACKGROUND Cardiovascular risk remains increased despite optimal low density lipoprotein cholesterol (LDL-C) level induced by intensive statin therapy. Therefore, recent guidelines recommend non-high density lipoprotein cholesterol (non-HDL-C) as a secondary target for preventing cardiovascular events. The aim of this study was to assess the efficacy and tolerability of omega-3 fatty acids (OM3-FAs) in combination with atorvastatin compared to atorvastatin alone in patients with mixed dyslipidemia. METHODS This randomized, double-blind, placebo-controlled, parallel-group, and phase III multicenter study included adults with fasting triglyceride (TG) levels ≥200 and <500 mg/dL and LDL-C levels <110 mg/dL. Eligible subjects were randomized to ATOMEGA (OM3-FAs 4,000 mg plus atorvastatin calcium 20 mg) or atorvastatin 20 mg plus placebo groups. The primary efficacy endpoints were the percent changes in TG and non-HDL-C levels from baseline at the end of treatment. RESULTS After 8 weeks of treatment, the percent changes from baseline in TG (-29.8% vs. 3.6%, P<0.001) and non-HDL-C (-10.1% vs. 4.9%, P<0.001) levels were significantly greater in the ATOMEGA group (n=97) than in the atorvastatin group (n=103). Moreover, the proportion of total subjects reaching TG target of <200 mg/dL in the ATOMEGA group was significantly higher than that in the atorvastatin group (62.9% vs. 22.3%, P<0.001). The incidence of adverse events did not differ between the two groups. CONCLUSION The addition of OM3-FAs to atorvastatin improved TG and non-HDL-C levels to a significant extent compared to atorvastatin alone in subjects with residual hypertriglyceridemia.

Abstract
OBJECTIVE HIV patients have increased atherosclerotic coronary vascular disease (ASCVD), thought to be mediated through inflammatory mechanisms. We hypothesized that among asymptomatic HIV-infected patients with subclinical coronary plaque, statin therapy would modulate unique inflammatory and cardiovascular proteins in relation to change in subclinical coronary plaque volume. We tested this hypothesis using a novel proteomics approach. DESIGN Forty HIV-infected participants were randomized to atorvastatin (40 mg/day) versus placebo, and underwent computed tomography coronary angiography to quantify plaque volume at baseline and 1 year. METHODS We used Olink Cardiovascular III and Cardiometabolic panels based on dual antibody epitope recognition with linked DNA amplification to compare change over time in 184 proteins in treatment versus placebo and in relation to change in coronary plaque volume. RESULTS Six proteins (TFPI, CCL24, NT-Pro BNP, MBL2, LTBR, PCOLCE) changed significantly in the atorvastatin versus placebo group, many in innate immune and other novel inflammatory pathways. Twenty-six proteins changed significantly in relationship to total coronary plaque volume over 1 year. Notably, many of these proteins changed only weakly in relationship to change in low-density lipoprotein (LDL). Overlapping these two broad discovery approaches, proteins involved in myocardial fibrosis/collagen formation and monocyte chemoattraction changed with statin treatment, in relationship to plaque volume, but not LDL. CONCLUSION This proof-of-concept study employing a proteomic discovery platform offers insight into statin effects on novel immune pathways relevant to ASCVD progression in HIV. Novel biomarker discovery may enhance precision medicine strategies to estimate the efficacy of targeted therapies to reduce ASCVD progression and events in HIV.

Abstract
OBJECTIVE Circulating oxidized low-density lipoprotein (oxLDL) levels are elevated in HIV-infected patients and have been associated with atherosclerosis. Statins have been shown to reduce plaque on coronary computed tomography angiography (cCTA) in HIV-infected individuals. Thus, we investigated the effect of statins on serum oxLDL levels and the relationship between changes in oxLDL and coronary atherosclerosis on cCTA in patients with HIV. DESIGN We previously conducted a 12-month randomized, placebo-controlled trial with atorvastatin in 40 HIV-infected patients on stable antiretroviral therapy with subclinical coronary atherosclerosis and low-density lipoprotein (LDL)-cholesterol less than 130 mg/dl. METHODS In the current analysis, patients underwent cCTA and measurements of serum oxLDL, sCD14, sCD163, lipoprotein phospholipase-A2, and fasting lipids at baseline and end of the study. RESULTS Nineteen patients were randomized to atorvastatin and 21 patients to placebo. Serum oxLDL decreased -22.7% (95% CI -28.7 to -16.7) in the atorvastatin group and increased 7.5% (95% CI -3.3 to 18.4) in the placebo group (P < 0.0001). Change in oxLDL significantly correlated with changes in noncalcified plaque volume, total plaque volume, positively remodeled plaque, and low attenuation plaque. The association between changes in oxLDL and noncalcified plaque volume was independent of the baseline 10-year Framingham risk, LDL, CD4 cell count, and viral load. CONCLUSION Statins lower oxLDL levels in HIV-infected patients, and reductions in oxLDL are related to improvements in coronary atherosclerosis, independent of traditional cardiovascular risk factors. Reductions in oxLDL may be one mechanism through which statins exert beneficial effects on reducing atherosclerosis in HIV-infected individuals.

Iranian journal of immunology : IJI. 2016;(1):16-26
Abstract
BACKGROUND Statins, widely used cholesterol-lowering agents, have also been demonstrated to have anti-inflammatory and immunomdulatory effects. OBJECTIVE To evaluate the effects of atorvastatin in combination with Interferon-β in the treatment of multiple sclerosis (MS) in a randomized controlled clinical trial. METHODS Multiple sclerosis patients were randomized independently, in a double blind design, into one of two treatment groups. Control group (n=45) received 30 μg/week interferon β-1a via intra-muscular injection. Atorvastatin-treated group (n=50) received interferon β-1a similar to control group in addition to atorvastatin (40 mg/day) for 18-months. All clinical and immunological variables were measured at the baseline and at the end of the study. RESULTS There was no significant difference between the two groups in the expanded disability status scale scores and the number of gadolinium-enhancing lesions during the 18-month treatment period. After 18 months, the levels of interleukin (IL)-4, IL-10, transforming growth factor-β and serum ferric reducing antioxidant power in the atorvastatin treatment group were significantly higher than the control group. Levels of IL-17, TNF-α and lymphocyte proliferation in the atorvastatin treatment group were significantly lower than the control group. CONCLUSION Although combined atorvastatin and interferon-β do not change the clinical course of MS, atorvastatin might have beneficial effects in MS treatment possibly through inducing anti-inflammatory responses.

Abstract
AIM: Circulating osteoprogenitors and receptor activator of nuclear factor kappa-B ligand (RANKL) expression in immune cells have been implicated in the pathogenesis of osteoporosis and vascular calcification. The role played by statin therapy in the bone-vascular axis is unknown. METHODS Twenty naïve postmenopausal osteoporotic hypercholesterolemic women were treated with Atorvastatin 40 mg/day for 3 months. Gene expression analysis was performed to assess modification in osteoprotegerin (OPG)/RANK/RANKL expression in isolated T cells and monocytes. A flow cytometry analysis was used to study changes in the levels of circulating osteoprogenitor cells. RESULTS After 3 months of treatment, Atorvastatin significantly reduced total cholesterol and LDL-C, without affecting HDL-C and triglycerides. Among circulating bone and phosphocalcium homeostasis markers, we found a significant increase in OPG levels (P < 0.01) and a modest reduction in osteocalcin (OCN) (P < 0.05). We also observed a significant reduction in RANKL expression in T cells (P < 0.05). No differences were found in the expression of RANK in T cells and RANKL and RANK in monocytes. OPG expression was low in both immune cell types and was not affected by the treatment. As for circulating osteoprogenitors, we found a significant reduction of CD34(+) BAP(+) (P < 0.05) and CD34(+) OCN(+) BAP(+) (P < 0.05) cells. In vitro studies showed that Atorvastatin reduced RANKL expression in activated human T-lymphoblastoid cells (Jurkat cell line). CONCLUSIONS Three-month Atorvastatin treatment leads to a reduction in circulating osteoprogenitor cells and RANKL expression in T cells, as well as increase in OPG serum levels. These data suggest that statins could have protective effects in the bone-vascular axis.

Abstract
PURPOSE A fixed-dose combination of a stain and an antihypertensive drug may be useful for the treatment of patients with hypertension and hyperlipidemia. It may also improve patient drug compliance to help control risk factors of cardiovascular disease. This study was designed to evaluate the blood pressure-lowering and cholesterol-lowering effect of a fixed-dose combination of irbesartan-atorvastatin compared with monotherapy by either agent over an 8-week treatment period. METHODS Patients with comorbid hypertension and hypercholesterolemia were screened for this randomized, double-blind, Phase III study. Eligible study patients were randomly assigned to test groups receiving a combination of irbesartan 300 mg and atorvastatin 40 mg or 80 mg (IRB300 + ATO40 and IRB300 + ATO80). Comparator groups comprised monotherapy groups with irbesartan 300 mg (IRB300) or atorvastatin 40 mg (ATO40) or atorvastatin 80 mg (ATO80), or placebo. Patients who were eligible at screening were subjected to a 4- to 6-week washout period before commencing 8 weeks of therapy per their assigned group. The primary efficacy end points were percent change in LDL-C and sitting diastolic blood pressure (DBP) levels from baseline to end of therapy. Tolerability profiles of combination therapy were compared with other groups. FINDINGS A total of 733 patients with comorbid hypertension and hypercholesterolemia were screened for this study; 230 eligible patients were randomized to treatment. The mean age of patients was 58.9 (8.5) years, and their mean body mass index was 25.8 (3.2) kg/m2. More than two thirds (70.9%) of the study patients were male. Mean LDL-C and sitting DBP levels at baseline were 149.54 (29.19) mg/dL and 92.32 (6.03) mm Hg, respectively. Percent reductions in LDL-C after 8 weeks were 46.74% (2.06%) in the IRB300 + ATO40 group and 48.98% (2.12%) in the IRB300 + ATO80 group; these values were 47.13% (3.21%) and 48.30% (2.98%) in the ATO40 and ATO80 comparator groups. Similarly, a reduction in sitting DBP after 8 weeks was -8.50 (1.06) mm Hg in the IRB300 + ATO40 group and 10.66 (1.08) mm Hg in the IRB300 + ATO80 group compared with 8.40 (1.65) mm Hg in the IRB300 group. The incidence rate for treatment-emergent adverse events was 22.27% and was similar between the monotherapy and combination groups. IMPLICATIONS A once-daily combination product of irbesartan and atorvastatin provided an effective, safe, and more compliable treatment for patients with coexisting hypertension and hyperlipidemia. ClinicalTrials.gov identifier: NCT01442987.

Abstract
AIMS: 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins) have multiple pleiotropic effects, such as anti-inflammatory and vascular endothelium protection, that are independent of their low-density-lipoprotein (LDL) cholesterol lowering effects. However, whether different statins exert diverse effects on inflammation, insulin resistance, and the progression of carotid atherosclerosis [as indicated by the intima-media thickness (CIMT)] in patients with dyslipidemia remains unclear. METHODS A total of 146 patients with hypercholesterolemia without known cardiovascular disease were randomly assigned to receive 5 mg/day of atorvastatin (n=73) or 1 mg/day of pitavastatin (n=73). RESULTS At baseline, age, gender, blood pressure, lipid profiles, and the serum monocyte chemoattractant protein (MCP)-1, homeostasis model assessment of insulin resistance (HOMA-IR) and CIMT values were comparable between the groups. After 12 months of treatment, atorvastatin and pitavastatin equally reduced the LDL cholesterol levels; however, atorvastatin increased the HOMA-IR by +26% and pitavastatin decreased this parameter by -13% (p<0.001). The MCP-1 values were reduced by -28% in the patients treated with pitavastatin and only -11% in those treated with atorvastatin (p=0.016). A greater percent decrease in the mean CIMT from baseline was observed in the patients treated with pitavastatin than in those treated with atorvastatin (-4.9% vs. -0.5%, p=0.020). CONCLUSIONS These data indicate that, while these agents significantly and equally reduce the LDL cholesterol levels, atorvastatin and pitavastatin have different effects on inflammation, insulin resistance, and the progression of carotid atherosclerosis in patients with dyslipidemia.
