Abstract
OBJECTIVE To observe the association between preprocedural high sensitivity C-reactive protein (hs-CRP) level and incidence of contrast induced acute kidney injury (CI-AKI) in acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention (PCI) and the impact of atorvastatin pretreatment on CI-AKI. METHODS According to the level of preprocedural hs-CRP, 270 ACS patients were divided into three groups: high hs-CRP group (hs-CRP ≥ 3 mg/L, n = 176), moderate hs-CRP group (hs-CRP 1-3 mg/L, n = 60) and normal hs-CRP group (hs-CRP < 1 mg/L, n = 34). According to the dosage of preprocedural atorvastatin, the high hs-CRP group was further divided into 10 mg group (n = 49), 20 mg group (n = 66) and 40 mg group (n = 61). Serum creatinine (Scr), blood urea nitrogen (BUN), cystatin C (Cys C), hs-CRP were measured at before and 24 hours, 48 hours after PCI. CCr and GFR were calculated according to Scr and Cys C. Risk factors for CI-AKI were determined by multivariate logistic regression analysis. RESULTS (1) Cys C was significantly increased and GFR after PCI significantly reduced in high and moderate hs-CRP groups compared with normal hs-CRP group (P < 0.05). (2) Incidence of CI-AKI was 43.18%, 38.33%, 20.59% in high, moderate and normal hs-CRP groups, respectively (P < 0.05). (3) In high hs-CRP group, postprocedural GFR was significantly higher while postprocedural Cys C and hs-CRP were significantly lower in 40 mg statin subgroup than 10 mg and 20 mg statin subgroups (P < 0.05), similar trends were documented when comparing 20 mg statin subgroup with 10 mg statin subgroup (P < 0.05). (4) Multivariate logistic regression analysis showed that pretreatment with high dose atorvastatin was a protective factor for post CI-AKI (20 mg atorvastatin: OR = 0.15, 95%CI 0.06 - 0.33, P = 0.001; 40 mg atorvastatin: OR = 0.10, 95%CI 0.04 - 0.23, P = 0.001), while high levels of preprocedural hs-CRP (OR = 2.06, 95%CI 1.01 - 4.23, P = 0.048), diabetes mellitus (OR = 10.71, 95%CI 5.29 - 21.70, P = 0.001), advanced age (OR = 2.64, 95%CI 1.05 - 6.63, P = 0.038) and renal failure (OR = 5.14, 95%CI 1.13 - 23.39, P = 0.034) were independent risk factors of CI-AKI. CONCLUSION High hs-CRP level is linked with the development of CI-AKI in ACS patients undergoing PCI and pretreatment with 40 mg atorvastatin is associated with lower incidence CI-AKI, possibly by reducing the postprocedural inflammation responses.

Abstract
The distribution of single intake atorvastatin in the content of very low, low and high density lipoproteins extracted from blood plasma of healthy volunteers by means of ultracentrifugal separation was investigated. The impact of atorvastatin on the composition of lipoprotein complexes was assessed. It is demonstrated that atorvastatin and its active derivatives transport mainly in the composition of high density lipoproteins. The distribution of atorvastatin and its biologically active metabolites has gender differences. It is established that in males atorvastatin increases the content of triacylglycerides of low density lipoproteins and cholesterol of high density lipoproteins in females.

Abstract
AIM To assess the effects of long-term multifactorial intervention on renal function and serum uric acid (SUA) levels and their association with estimated cardiovascular disease (eCVD) risk and actual CVD events. METHODS This prospective, randomized, target-driven study included 1123 subjects (45.6% men, age 45-65 years) with metabolic syndrome (MetS) but without diabetes or CVD. Patients were randomized to multifactorial treatment. Atorvastatin was titrated from 10-80 mg/day aiming at a low density lipoprotein cholesterol (LDL-C) target of <100 mg/dl (group A) or an LDL-C target of <130 mg/dl (group B). Changes in estimated glomerular filtration rate (eGFR) and SUA levels were recorded in all patients and in the subgroup with stage 3 chronic kidney disease (CKD; eGFR = 30-59 ml/min/1.73 m(2); n = 349). We used ANOVA to compare changes within the same group, unpaired Student t-test to compare results between groups at specific time points, and log-rank test to compare event free survival. RESULTS The eCVD-risk reduction was greater in group A. In the overall study population, eGFR increased by 3.5% (p < 0.001) and SUA levels fell by 5.6% (p < 0.001). In patients from group A with stage 3 CKD (group A1; n = 172), eGFR increased by 11.1% (p < 0.001) from baseline and by 7.5% (p < 0.001) in group B1 (n = 177; p < 0.001 vs. the change in group A1). The corresponding fall in SUA levels was 10.7% in group A1 (p < 0.001 vs. baseline) and 8.3% in group B1 (p < 0.001 vs. baseline and group A1). These changes were mainly attributed to atorvastatin treatment. Among the CKD stage 3 patients there were no CVD events in group A1, while 6 events occurred in group B1 (p = 0.014). CONCLUSIONS Multifactorial intervention in patients with MetS without established CVD improved renal function and reduced SUA levels. These changes were more prominent in stage 3 CKD patients and might have contributed to the reduction in eCVD risk and clinical events.

Abstract
Dyslipidaemia is one of the most important modifiable risk factors for coronary disease. Despite the availability of highly effective lipid-modifying agents, many patients still do not reach lipid targets established by national guidelines. This, in turn, has prompted a resurgence of the search for drugs and algorithms that favourably affect the lipid profile. The preventive efforts made so far have demonstrated that lowering low density lipoprotein-cholestrol is one action that individuals and populations can do with significant success in delaying the onset of clinical events, but at the same time one should not neglect high density lipoprotein and triglyceride levels as they also play a significant role in the risk of developing complications. Combination regimens should be considered for use in patients who fail to meet target values and are compliant with their current therapy. Although the use of combination therapy varies considerably across the globe, this treatment strategy is becoming increasingly more common as treatment guidelines recommend more aggressive therapy in order to achieve lower target cholesterol goals.

Abstract
Contrast-induced nephropathy (CIN) impairs clinical outcome in patients undergoing angiographic procedures. The aim of this study was to investigate whether short-term high-dose atorvastatin load decreases the incidence of CIN after percutaneous coronary intervention (PCI). Statin-naive patients with acute coronary syndrome undergoing PCI (n = 241) randomly received atorvastatin (80 mg 12 hours before intervention with another 40-mg preprocedure dose, n = 120) or placebo (n = 121). All patients had long-term atorvastatin treatment thereafter (40 mg/day). Primary end point was incidence of CIN defined as postintervention increase in serum creatinine ≥0.5 mg/dl or >25% from baseline. Five percent of patients in the atorvastatin arm developed CIN versus 13.2% of those in the placebo arm (p = 0.046). In the atorvastatin group, postprocedure serum creatinine was significantly lower (1.06 ± 0.35 vs 1.12 ± 0.27 mg/dl in placebo, p = 0.01), creatinine clearance was decreased (80.1 ± 32.2 vs 72.0 ± 26.6 ml/min, p = 0.034), and C-reactive protein peak levels after intervention were decreased (8.4 ± 10.5 vs 13.1 ± 20.8 mg/l, p = 0.01). Multivariable analysis showed that atorvastatin pretreatment was independently associated with a decreased risk of CIN (odds ratios 0.34, 95% confidence interval 0.12 to 0.97, p = 0.043). Prevention of CIN with atorvastatin was paralleled by a shorter hospital stay (p = 0.007). In conclusion, short-term pretreatment with high-dose atorvastatin load prevents CIN and shortens hospital stay in patients with acute coronary syndrome undergoing PCI; anti-inflammatory effects may be involved in this renal protection. These results lend further support to early use of high-dose statins as adjuvant pharmacologic therapy before percutaneous coronary revascularization.

Abstract
BACKGROUND The fixed-dose combination containing the antihypertensive agent amlodipine and the statin, atorvastatin, is the first combination of its kind designed to treat two risk factors for cardiovascular disease (CVD), i.e., hypertension and dyslipidemia. In this study, blood pressure and lipid lowering effects of combination of amlodipine and atorvastatin were evaluated in uncontrolled hypertensive patients. METHODS Thirty patients both male and female in the age group 35-60 years attending the Hypertensive Clinic of PMRC FJMC suffering from uncontrolled hypertension were selected. Baseline blood pressure was checked after half hour rest in sitting and standing position using mercury sphygmomanometer. Blood sample was collected from all patients after overnight fasting for assessment of serum cholesterol, triglycerides, LDL and HDL cholesterol levels. They were prescribed with fixed dose combination of 5 mg amlodipine and 10 mg atorvastatin. Patients were followed for their blood pressure measurement after every 4 weeks up to 12 weeks. At the end of 12 weeks their fasting blood sample was taken again for determination of serum cholesterol, triglyceride, LDL and HDL cholesterol levels. RESULTS Systolic blood pressure after 4, 8 and 12 weeks was significantly lower at all intervals from baseline. When systolic blood pressure after 8 and 12 weeks was compared with 4 weeks, the effect was again significant (p=0.024, p=0.002 respectively).There was no significant reduction seen in 8 versus 12 weeks (p=0.493). Diastolic blood pressure at 4, 8 and 12 weeks was significantly lower from baseline. Diastolic blood pressure after 4 and 8 weeks when compared with 8 and 12 weeks was not significantly low (p=0.99 and 0.91 respectively). Lipid profile of the patients was significantly reduced from baseline after twelve weeks of fixed dose combination of treatment (p<0.000). CONCLUSION Combination therapy proved to be effective in controlling hypertension and dyslipidemia than single pill. It also improved patient's compliance. It is suggested that polypill should be prescribed instead of multiple drugs.

Abstract
AIM Diabetes is associated with abnormalities in lipid profile and increased oxidative stress. Statins are preferred agents in diabetic patients due to their antioxidant and LDL-C lowering effects. This study is designed to compare the effects of atorvastatin and rosuvastatin on low density lipoprotein cholesterol (LDL-C), lipid hydroperoxide (LOOH), total oxidant status (TOS) and total antioxidant capacity (TAC) in diabetic patients with hyperlipidemia. MATERIALS AND METHODS Sixty two patients who have type 2 diabetes mellitus with serum LDL levels more than 100mg/dL were randomly assigned to receive atorvastatin 20mg (n=31) or rosuvastatin 10mg (n=31). Blood tests were performed at the beginning of the study and after three months. RESULTS There were no statistically significant differences in the pre- and after treatment levels of the LDL-C between groups. TAC values were increased in both groups and statistically significant in the former group (p=0.007). There was no difference between the change percentages ((after treatment TAC-pretreatment TAC)/pretreatment level) of TAC between two treatment groups. The effects of two drugs on the other oxidative parameters were not significantly different. CONCLUSION Both atorvastatin and rosuvastatin may be helpful in reducing increased oxidative stress in diabetic patients with hyperlipidemia.

Abstract
OBJECTIVE To evaluate the achievement of individual and combined lipid and lipoprotein/biomarker targets as specified by treatment guidelines with the combination of fenofibric acid and statin therapy in patients with mixed dyslipidemia. METHODS Data for the post hoc analyses were derived from three 12-week controlled studies and a 52-week extension study. Patients were treated with fenofibric acid 135 mg; low-, moderate-, or high-dose statin (rosuvastatin 10, 20, or 40 mg; atorvastatin 20, 40, or 80 mg; or simvastatin 20, 40, or 80 mg); or fenofibric acid + low- or moderate-dose statin in the controlled studies; and with fenofibric acid + moderate-dose statin in the extension study. Achievement of risk-stratified low-density lipoprotein cholesterol (LDL-C), non-high-density lipoprotein cholesterol (non-HDL-C), and apolipoprotein B (ApoB) targets; and optimal levels of ApoB <90 mg/dL, HDL-C >40/50 mg/dL in men/women, triglycerides (TG) < 150 mg/dL, and high-sensitivity C-reactive protein <2 mg/L were assessed. RESULTS In the controlled studies, significantly lower percentage of high-risk patients treated with fenofibric acid + moderate-dose statin, and significantly higher percentage of high-risk patients treated with fenofibric acid + low-dose statin, compared with corresponding-dose statin monotherapies, achieved their LDL-C (51.3% vs. 72.9%, p < 0.001) and non-HDL-C targets (53% vs. 38%, p = 0.02), respectively. Among all patients, optimal levels of ApoB, HDL-C, TG, and the combined target of LDL-C + non-HDL-C + ApoB + HDL-C + TG were achieved by higher percentage of patients treated with fenofibric acid + low- and moderate-dose statin versus corresponding dose-statin monotherapies (p ≤ 0.04 for all comparisons). In the extension study, significantly (p < 0.001 for all comparisons) higher percentage of patients had achieved individual and combined targets at final visit, compared with baseline. CONCLUSIONS In patients with mixed dyslipidemia, short-term treatment with the combination of fenofibric acid and low- or moderate-dose statin resulted in comparable or more patients achieving individual targets of non-HDL-C, ApoB, HDL-C, and TG, and combined targets for these parameters and LDL-C, compared with corresponding-dose statin monotherapy. In the long-term study, the proportion meeting these targets was significant, compared with baseline. Limitations include the post hoc nature of the analysis, and the fact that all patients had mixed dyslipidemia and majority were white, which limits generalization to other populations.

Abstract
This study aimed to assess the efficacy and tolerability of atorvastatin in Tanner stage (TS) 1 patients ages 6 to 10 years and TS ≥ 2 patients ages 10 to <18 years with genetically confirmed heterozygous familial hypercholesterolemia (HeFH) and a low density lipoprotein cholesterol (LDL-C) level of 4 mmol/l (155 mg/dl) or higher. In this open-label, 8-week study, 15 TS 1 children were treated initially with atorvastatin 5 mg/day and 24 TS ≥ 2 children with 10 mg/day. Doses were doubled at week 4 if the LDL-C target (<3.35 mmol/l [130 mg/dl]) was not achieved. The efficacy variables were the percentage change from baseline in LDL-C, total cholesterol (TC), triglycerides (TG), high density lipoprotein cholesterol (HDL-C), very low density lipoprotein cholesterol (VLDL-C), and apolipoprotein (Apo) A-I and Apo B. Safety evaluations included clinical monitoring, subject-reported adverse events (AEs), vital signs, and clinical laboratory tests. The mean values for LDL-C, TC, VLDL-C, and Apo B decreased by week 2 among all TS 1 and TS ≥ 2 patients, whereas TG, HDL-C, and Apo A-I varied considerably from week to week. After 8 weeks, the mean reduction in LDL-C was -40.7% ± 8.4 for the TS 1 children and -39.7% ± 10.3 for the TS ≥ 2 children. For the TS 1 patients, the mean reductions were -34.1% ± 6.9 for TC and -6.0% ± 32.1 for TG. The corresponding changes for the TS ≥ 2 patients were -35.6% ± 9.5 for TC and -21.1% ± 29.7 for TG. Four patients experienced mild to moderate treatment-related AEs. No serious AEs or discontinuations were reported. Overall, no difference in safety or tolerability was observed between the younger and older cohorts. Across the range of exposures after atorvastatin 5 to 10 mg (TS 1) or atorvastatin 10 to 20 mg (TS ≥ 2) doses for 8 weeks, clinically meaningful reductions in LDL-C, TC, VLDL-C, and Apo were observed with atorvastatin in pediatric patients who had HeFH. Atorvastatin also was well tolerated in this population.

Abstract
BACKGROUND AND AIM The effect of ezetimibe-statin combination on inflammatory markers in acute coronary syndrome is unknown. The aim of our study is to evaluate the effect of this combination on the lipid profile, the CRP hs and the sCD40 ligand levels in acute coronary syndrome (ACS) patients. METHODS This is a randomized, double-blind study including 93 patients admitted for ACS randomized in 2 groups, ezetimibe 10 mg + atorvastatin 10 mg vs atorvastatin 20 mg + placebo, for 12 weeks follow-up; blood samples were collected for lipid profile, ALT, AST, CRP and sCD40L at baseline, 12 hours, 4 weeks, and 12 weeks. RESULTS There was no significant difference in total cholesterol levels, HDL, LDL, CRP, but there was a significant decrease in sCD40L levels in the ezetimibe combination group, with less side effects in the combination group, mainly myalgia (p = 0.012). CONCLUSION Ezetimibe combination with low dose statin in patients in acute coronary syndrome could be a safe, potent therapy to reduce LDL level with antiinflammatory effect.

Abstract
OBJECTIVE To investigate whether a proactive multifactorial risk factor intervention strategy using single-pill amlodipine/atorvastatin (5/10, 10/10 mg) in addition to other antihypertensive and lipid-lowering therapy, as required, resulted in greater reduction in calculated Framingham 10-year coronary heart disease (CHD) risk compared with usual care (UC) after 52-weeks treatment. RESEARCH DESIGN AND METHODS Prospective, multinational, open-label, cluster randomized trial, with the investigator as the unit of randomization. Eligible hypertensive patients were 35-79 years of age, with ≥3 additional cardiovascular risk factors, but no history of CHD and baseline total cholesterol (TC) ≤6.5 mmol/l. CLINICAL TRIAL REGISTRATION www.ClinicalTrials.gov ; trial identifier NCT00407537. MAIN OUTCOME MEASURE The primary endpoint was calculated Framingham 10-year CHD risk at 52 weeks. RESULTS Of the 140 randomized sites, 136 sites contributed 1461 patients. Mean baseline age and low-density lipoprotein cholesterol (LDL-C) were comparable between treatment arms. Mean baseline BP (150.3/89.7 vs. 144.3/86.5 mmHg) and Framingham CHD risk (20.0 vs. 18.1%) were higher in the proactive intervention versus the UC arm (p < 0.002 for both). At week 52, mean CHD risk was 12.5% in the proactive intervention arm and 16.3% in the UC arm (p < 0.001). The difference, observed at weeks 16 and 52, was primarily driven by significant differences in systolic BP and in TC between the two arms. Overall, adverse events (AEs) were reported in 48.8% and 44.0% of patients in the proactive intervention and the UC arm, respectively. Although there were differences in the incidence of AEs between the treatment arms, the AE profile in the proactive intervention arm was consistent with previous safety experience for this medication. CONCLUSIONS A proactive multifactorial risk factor intervention strategy that simultaneously treated both BP and cholesterol regardless of individual risk factors per se, is more effective in reducing calculated Framingham 10-year CHD risk than UC in patients with hypertension and additional risk factors.

Abstract
We investigated the effectiveness of pioglitazone in the treatment of patients with coronary heart disease in combination with MS. In the conduct of research revealed that the addition to standard therapy in patients with coronary heart disease on the background of metabolic syndrome pioglitazone led to a reliable slight decrease in body weight, BMI, hip circumference, waist their relationship. Receiving pioglitazone also significantly reduces the concentration of immunoreactive insulin and blood glucose levels, significantly altered lipid metabolism, which generally leads to a lower level of systemic inflammation, metabolism and reduces the severity of insulin resistance. This allows you to recommend the inclusion of pioglitazone in complex coronary heart disease and metabolic syndrome.

Abstract
A 67-year old man was hospitalized due to an aorto-coronary bypass and cecal perforation. After administration of atorvastatin, amiodarone, and fluconazole, rhabdomyolysis developed with electrolyte disturbances (hyperphosphatemia, hyopcalcemia) and a massive increase in creatine kinase and myoglobin. In the clinical course, other complications manifested such as acute renal failure, critical illness myopathy, acute gout on the knee, and sternal infection with coagulase-negative staphylococci. After stopping the assumed causal agents and treating the complications, the patient could be transferred for rehabilitation after a more than two months hospital stay. We discuss the causes and symptoms of muscle diseases as well as the epidemiology, mechanisms, treatment, and prevention of drug-induced myopathies with a focus on statins.

Abstract
Alzheimer disease (AD) is an age-related neurodegenerative disorder characterized by progressive memory loss, inability to perform the activities of daily living and personality changes. Unfortunately, drugs effective for this disease are limited to acetylcholinesterase inhibitors that do not impact disease pathogenesis. Statins, which belong to the class of cholesterol-reducing drugs, were proposed as novel agents useful in AD therapy, but the mechanism underlying their neuroprotective effect is still unknown. In this study, we show that atorvastatin may have antioxidant effects, in aged beagles, that represent a natural higher mammalian model of AD. Atorvastatin (80 mg/day for 14.5 months) significantly reduced lipoperoxidation, protein oxidation and nitration, and increased GSH levels in parietal cortex of aged beagles. This effect was specific for brain because it was not paralleled by a concomitant reduction in all these parameters in serum. In addition, atorvastatin slightly reduced the formation of cholesterol oxidation products in cortex but increased the 7-ketocholesterol/total cholesterol ratio in serum. We also found that increased oxidative damage in the parietal cortex was associated with poorer learning (visual discrimination task). Thus, a novel pharmacological effect of atorvastatin mediated by reducing oxidative damage may be one mechanism underlying benefits of this drug in AD.

Abstract
AIMS Cardiovascular disease (CVD) is the most common cause of death worldwide. Pharmaceutical risk reduction with high-intensity statin therapy is advisable for high-risk patients. Clinicians face a conflict between prescribing for cost (simvastatin 80 mg) or for efficacy (atorvastatin 80 mg). The aim of this audit was to examine the use, efficacy and tolerability of high intensity statin treatment (simvastatin 80 mg; atorvastatin 80 mg) in primary care. METHODOLOGY Electronic medical records were examined from two general practitioners' surgeries. Analyses involved Mann-Whitney U and χ(2) tests. RESULTS A total of 116 patients had taken simvastatin 80 mg or atorvastatin 80 mg. Patients were similar between treatment groups: mostly men (62.9%), over 60 years old (68.1%), non-smokers (81.0%) taking statins for secondary prevention (56.9%). More patients on simvastatin withdrew from treatment as a result of inefficacy (49.3% vs. 23.2%, p=0.025) compared with the atorvastatin group. Furthermore, patients on simvastatin were more likely to be failing conventional targets of lipid control, compared with patients on atorvastatin 80 mg (43.5% vs. 21.3%, p=0.006). Tolerability was similar between the two groups. DISCUSSION UK guidelines recommend simvastatin 80 mg as an economic choice, despite scant evidence at this dose and recent safety concerns. Conversely, robust evidence exists for atorvastatin 80 mg. Head-to-head clinical trials or clinical studies comparing these agents are lacking. The present study suggests that atorvastatin 80 mg compares favourably to simvastatin in terms of efficacy and has a similar tolerability profile. CONCLUSION This retrospective observational study suggests that despite national guidelines, atorvastatin 80 mg is used in clinical practice and is more effective and at least as well tolerated as simvastatin 80 mg.

Abstract
OBJECTIVE To evaluate whether taking atorvastatin for long time has positive effects on age-related renal impairment. METHODS 20-month-age normal female Wistar rats were divided into three groups (n = 9). First group were fed atorvastatin 10 mg/(kg x d). Second group were fed atorvastatin 1 mg/(kg x d). Third group were fed the same volume normal saline served as control. All the rats were sacrificed after four months. 3-month-age normal female Wistar rats (n = 9) also served as normal control. Kidney weight, serum creatinine (Scr) and blood-lipoids were measured. Paraffin sections of renal tissues were stained with PAS and Sirius red. Sclerosis index of glomerulus was calculated. RESULTS Renal mass diminution was found in all the groups of aging rats. Scr was decreased in the group of aging rats with atorvastatin 1 mg/(kg x d). The level of blood-lipoids of aging rats was higher than that of young rats. The level of serum cholesterol and low-density lipoprotein (LDL) were decreased in first group (both P < 0.05) and only LDL decreased in second group (P < 0.05). Morphological changes of aging kidney were focal segmental glomerulosclerosis, widen of mesangial region, infiltration of inflammatory cells and sclerosis of arteriole. The treatment of atorvastatin improved the pathologic changes in the aging rats significantly, especially in the first group. CONCLUSION Taking atorvastatin for long time can notably improve the pathological changes of aging kidney. All these effects may be induced by lowing of blood-lipoids, relieving the sclerosis of renal arteriole and reducing the infiltration of inflammatory cells.

Abstract
PURPOSE PF299804 is a potent, orally available, irreversible inhibitor of tyrosine kinase human epidermal growth factor receptors (HER) 1 (EGFR), HER2, and HER4. This first-in-human study investigated the safety, tolerability, pharmacokinetics, and pharmacodynamics of PF299804 in patients with advanced solid malignancies. EXPERIMENTAL DESIGN PF299804 was administered once daily continuously (schedule A) and intermittently (schedule B). Dose escalation proceeded until intolerable toxicities occurred. Skin biopsies were taken predose and after 14 days of treatment to establish a pharmacokinetic/pharmacodynamic relationship. Tumor response was measured once every 2 cycles. Efficacy was correlated with tumor genotypes in non-small cell lung cancer (NSCLC) patients. RESULTS 121 patients were included (111 in schedule A, 10 in schedule B). The maximum tolerated dose (MTD) was 45 mg/d. Dose-limiting toxicities included stomatitis and skin toxicities. Most adverse events were mild and comprised skin toxicities, fatigue, and gastrointestinal side-effects including diarrhea, nausea, and vomiting. Pharmacokinetic analyses revealed dose-dependent increases in PF299804 exposure associated with target inhibition in skin biopsy samples. Fifty-seven patients with non-small cell lung cancer (NSCLC) were treated in this study. Four patients, all previously treated with gefitinib or erlotinib (2 with exon 19 deletions, 1 with exon 20 insertion, 1 mutational status unknown), had a partial response to PF299804. CONCLUSIONS The MTD of PF299804 is 45 mg/d. Both continuous and intermittent treatment schedules were well tolerated, and encouraging signs of antitumor activity were observed in gefitinib/erlotinib treated NSCLC patients.

Abstract
OBJECTIVE In this study, our aim was to evaluate the effect of a higher dose of atorvastatin on the recurrence rate of atrial fibrillation (AF) after electrical cardioversion (EC) in addition to antiarrhythmic therapy. SUBJECTS AND METHODS 48 patients with persistent AF were included in this study. The patients were randomized to an atorvastatin 40-mg treatment group and a control group. Atorvastatin was started 3 weeks before EC and was continued for 2 months after EC. EC was performed using biphasic shocks after 3 weeks of treatment with the orally administered anticoagulant warfarin. Lipid and inflammatory parameters (high-sensitivity C-reactive protein, white blood cell count and fibrinogen level) were evaluated at the baseline and before EC. The endpoint of this study was electrocardiographically confirmed recurrence of AF of >10 min. RESULTS There were no significant differences in baseline characteristics and lipid and inflammatory marker levels between the treatment and control groups. Total cholesterol and low-density lipoprotein levels were significantly decreased in patients taking atorvastatin for 2 months compared with baseline values (174 ± 31 vs. 129 ± 25 mg/dl, p = 0.001, and 112 ± 23 vs. 62 ± 20 mg/dl, p = 0.001, respectively), while no significant change occurred in control patients (168 ± 26 vs. 182 ± 29 mg/dl, p = 0.07, and 99 ± 18 vs. 108 ± 26 mg/dl, p = 0.1, respectively). At the end of the 2-month follow-up period, 9 patients (20.5%) experienced AF recurrence, and there was no significant difference in AF recurrence rate between the treatment and control groups (26 vs. 13%; p = 0.2). CONCLUSION Atorvastatin therapy prior to EC does not prevent the recurrence of arrhythmia in patients with persistent AF who are receiving antiarrhythmic therapy.

Abstract
AIMS To compare the renal effects of low- vs. high-dose atorvastatin in patients with Type 2 diabetes mellitus and optimally managed early renal disease. METHODS We compared the 2-year progression of nephropathy in a double-blind randomized controlled trial of atorvastatin 80 mg/day (n = 60) vs. 10 mg/day (n = 59) in patients with Type 2 diabetes with microalbuminuria or proteinuria [mean (sd): age 64 years (10 years); HbA(1c) 7.7% (1.3%), 61 mmol/mol (10 mmol/mol); blood pressure 131/73 mmHg; renin-angiotensin system blocker use > 80%; dual blockade > 67%] recruited from diabetes clinics in Greater Manchester. RESULTS Over (mean) 2.1 years of follow-up, the Modification of Diet in Renal Disease estimated glomerular filtration rate declined by 3 ml min(-1) 1.73 m(-2) in the combined group. The mean (95% CI) between-group difference during follow-up was not significant [2.2 ml min(-1) 1.73 m(-2) (-1.1 to 5.4 ml min(-1) 1.73: m(-2) ), P = 0.20] after adjusting for baseline differences in renal function; positive difference favours 80 mg dose. Similarly, there was no significant difference in creatinine clearance by Cockcroft and Gault [2.5 ml/min (-2.4 to 7.3 ml/min), P = 0.32]; serum creatinine/24-h urine collections [4.0 ml/min (-4.8 to 12.7 ml/min), P = 0.38]; cystatin C (P = 0.69); or 24-h urine protein or albumin excretion (P = 0.92; P = 0.93). We recorded no significant between-group differences in deaths or adverse events. CONCLUSIONS In patients with Type 2 diabetes with early renal disease, we found no statistical difference in renal function between those taking high- or low-dose atorvastatin over 2 years. We cannot exclude a beneficial effect of < 1.6 ml min(-1) 1.73 m(-2) year(-1) on Modification of Diet in Renal Disease estimated glomerular filtration rate, or if blood pressure management or if renin-angiotensin system blocker use had not been optimized.

Abstract
BACKGROUND AND AIM OF THE STUDY Following the SEAS and SALTIRE studies in moderate-to-severe aortic stenosis (AS), it was postulated that the statin treatment had been initiated far too late during the disease course. Thus, the study aim was to assess the effect of four-week atorvastatin treatment (20 mg/day) on levels of calcification biomarkers in patients with early-stage disease (i.e., aortic sclerosis or mild AS). METHODS In total, 33 patients (18 males, 15 females; mean age 70 +/- 8 years) with aortic sclerosis or mild AS, who had never received statin treatment, were enrolled into the study. According to their baseline lipid levels, 17 patients were hypercholesterolemic and 16 normocholesterolemic. Hence, rather than apply randomization, all patients were administered atorvastatin at a moderate dose level. Plasma levels of three biomarkers of calcification were measured, namely osteoprotegerin (OPG), osteopontin (OPN), and soluble receptor activator of nuclear factor (NF)-kappaB ligand (sRANKL). RESULTS Plasma levels of all three biomarkers were decreased after atorvastatin treatment. OPG levels fell from 13.23 +/- 5.33 to 10.92 +/- 5.34 pmol/l (p < 0.05), sRANKL from 105.36 +/- 69.47 to 86.74 +/- 71.36 ng/ml (p < 0.05), and OPN from 31.60 +/- 20.29 to 28.45 +/- 15.98 ng/ml (p = NS). When comparing patients with no/mild valvular calcification to those with moderate valvular calcification, only the OPG level before atorvastatin was statistically higher in patients from the latter group: 11.44 +/- 4.51 versus 16.09 +/- 5.67 pmol/l (p < 0.05). CONCLUSION Atorvastatin, at a dose level of 20 mg per day, reduced the plasma levels of calcification biomarkers in patients with aortic sclerosis and mild AS. The pre-atorvastatin OPG level was significantly higher when the aortic valve was moderately calcified, despite a persistent low transvalvular gradient.

In vivo carotid plaque MRI using quantitative T2* measurements with ultrasmall superparamagnetic iron oxide particles: a dose-response study to statin therapy. NMR IN BIOMEDICINE 2011; 24:89-95.

Abstract
This study investigates T(2)* quantification in carotid plaques before and after the administration of ultrasmall superparamagnetic iron oxide particles (USPIOs) in a cohort of patients receiving statin therapy. Phantom studies were performed using gels with varying concentrations of USPIOs. In the phantom study, 12 gels were prepared with a range of freely distributed concentrations of USPIO nanoparticles (0-0.05 mg/mL). Relative signal intensity measurements were obtained from a T(2)*-weighted sequence as well as quantitative T(2)* (qT(2)*) measurements. In the patient study, 40 patients with >40% carotid stenosis were randomised to low- and high-dose statin therapy (10 and 80 mg of atorvastatin). Pre- and post- (36 h) USPIO-enhanced MRI were performed at baseline, and at 6 and 12 weeks. A linear mixed-effects model was applied to account for the inherent correlation of multiple-plaque measurements from the same patient and to assess dose-response differences to statin therapy. In the phantom study, the T(2)*-weighted sequence demonstrated an initial increase (T(1) effect), followed by a decrease (T(2)* effect), in relative signal intensity with increasing concentrations of USPIO. The qT(2)* values decreased exponentially with increasing concentrations of USPIO. In the patient study, there was a highly significant difference in post-USPIO T(2)* measurements in plaques between the low- and high-dose statin groups. This was observed for both the difference in qT(2)* measurements (post-USPIO minus pre-USPIO) (p < 0.001) and for qT(2)* post-USPIO only (p < 0.001). The post-USPIO qT(2)* values were as follows: baseline: low dose, 13.6 ± 5.5 ms; high dose, 12.9 ± 6.2 ms; 6 weeks: low dose, 13.3 ± 6.7 ms; high dose, 14.3 ± 7.7 ms; 12 weeks: low dose, 14.0 ± 7.6 ms; high dose, 18.3 ± 11.2 ms. It can be concluded that qT(2)* measurements provide an alternative method of quantifying USPIO uptake. These results also demonstrate that changes in USPIO uptake can be measured using post-USPIO imaging only.
