Effects of Preoperative Atorvastatin Treatment On Erectile Function After Radical Prostatectomy: Results From a Subgroup of ESTO1, a Randomized,Double-Blind,Placebo-Controlled Study

IntroductionErectile dysfunction is common after radical prostatectomy because of damage to the cavernous nerves. Thus, it is important to identify new ways to avoid this problem. For example, statins have shown positive effects on erectile function and may have anti-inflammatory effects that improve recovery after surgery.AimThe aim of this exploratory analysis of a subgroup from ESTO1, a randomized, double-blind, placebo-controlled study, was to evaluate the preoperative use of atorvastatin on erectile function after radical prostatectomy.MethodPatients were randomized to either 80 mg atorvastatin or placebo daily before undergoing radical prostatectomy from study inclusion to the day of surgery. Altogether 118 men with prostate cancer and scheduled for radical prostatectomy were asked to fill out the 5-item version of the International Index of Erectile Function (IIEF-5) questionnaire before surgery and at 3, 6, 9, and 12 months after surgery.Main Outcome MeasurementsThe study was exploratory, with the main outcome being the overall difference between IIEF-5 scores in the 2 groups at 12 months. Several hypotheses generating sub-analyses were conducted.ResultsOverall, 85% filled out the IIEF-5 questionnaire before their operation and 85%, 81%, 78%, and 78% completed it at 3, 6, 9, and 12 months follow-up, respectively. 52% of men had information available at all time points. There were no statistically significant differences between the groups at baseline in either erectile function, comorbidities, or tumor characteristics. The median duration of use of atorvastatin and placebo before surgery was 27 and 25 days, respectively. Preoperative atorvastatin treatment had no statistically significant effect on erectile function after prostatectomy as compared with placebo, although IIEF-5 scores were higher at all time points in the statin arm. Furthermore, atorvastatin treatment compared with placebo improved IIEF-5 scores at 12 months after surgery when the cavernous nerves were at least partially intact bilaterally (P < .04, n = 65); however, after full bilateral or unilateral nerve-sparing, the difference was not statistically significant.Clinical ImplicationShort-term statin treatment did not improve recovery of erectile function after prostatectomy; however, further studies are needed before final conclusions.Strengths & LimitationsThis was a randomized placebo-controlled study. Original ESTO1 study was designed to detect a difference in prostate cancer biomarkers.ConclusionShort-term atorvastatin treatment before radical prostatectomy had no statistically significant effect on the recovery of erectile functions in a non-selected cohort of patients undergoing radical prostatectomy. Further studies will be needed to clarify the role of long-term atorvastatin use before and after prostatectomy.Siltari A, Riikonen J, Fode M, et al.

Statin-associated muscle symptoms in coronary patients: design of a randomized study

Objectives. Estimate the effect of atorvastatin on muscular symptom intensity in coronary patients with subjective statin-associated muscle symptoms (SAMS) and to determine the association with blood levels of atorvastatin and its metabolites, to obtain an objective marker for true SAMS. Design. A randomized, double-blinded, cross-over study will include 80 coronary patients with subjectively reported SAMS during ongoing atorvastatin therapy or previous muscle symptoms that led to discontinuation of atorvastatin. Patients will be randomized to 7-weeks treatment with atorvastatin 40?mg/day in the first period and matched placebo in the second 7-weeks period, or placebo in the first period and atorvastatin in the second period. Each period is preceded by 1-week wash-out. A control group (n?=?40) without muscle symptoms will have 7 weeks open treatment with atorvastatin 40?mg/day. Blood samples will be collected at baseline and at the end of each treatment period, and muscular symptoms will be rated by the patients weekly using a Visual Analogue Scale (VAS). The primary outcome is the difference in aggregated mean VAS scores between the last three weeks of atorvastatin treatment and of placebo treatment. The main purpose is to develop an objective marker for true SAMS, by comparing SAMS associated with blinded atorvastatin treatment with blood concentrations of atorvastatin and its metabolites. Diagnostic and discrimination performance will be determined. Conclusions. The study provides new knowledge on SAMS in coronary patients and may contribute to more personalized statin treatment and monitoring, fewer side-effects and consequently improved adherence and lipid management in future practice.     

阿托伐他汀调控PERK/eIF2α/CHOP通路减轻造影剂诱导的大鼠肾小管上皮细胞凋亡

目的研究造影剂肾病大鼠肾脏中葡萄糖调节蛋白78(GRP78)、内质网调节激酶(PERK)、真核起始因子2α(eIF2α)及C/EBP同源蛋白质(CHOP)的表达情况，探讨内质网应激在造影剂肾病发病中的作用及阿托伐他汀的干预作用。 方法60只大鼠随机分为4组：对照组、模型组和高、低剂量阿托伐他汀组(80 mg，40 mg)，每组15只。分别于注射造影剂后24、48、72 h留取血清；检测各组大鼠的血清尿素氮(BUN)、血清肌酐(Scr)；TUNEL法及Western印迹法测casepase-3的表达检测肾小管上皮细胞凋亡；免疫组化和Western印迹法检测各组大鼠肾组织GRP78、p-eIF2α、p-PERK及CHOP的表达。 结果与对照组相比，模型组大鼠BUN、Scr显著升高，细胞凋亡严重，GRP78、p-eIF2α、p-PERK及CHOP的表达均显著升高(P< 0.05);与模型组相比，高、低剂量阿托伐他汀组，BUN、Scr显著下降，凋亡指数降低，GRP78、p-eIF2α、p-PERK及CHOP的表达显著下调，但仍高于对照组，差异均达到统计学意义(P<0.05)；高、低剂量阿托伐他汀组之间上述各指标差异均不显著。 结论PERK/eIF2α/CHOP通路介导的内质网应激可能参与大鼠造影剂肾病的发生发展；阿托伐他汀在造影剂诱导的肾脏损伤中发挥保护作用，这可能与其调节PERK/eIF2α/CHOP通路，从而减轻内质网应激有关。     

Coenzyme Q10 supplementation improves acute outcomes of stroke in rats pretreated with atorvastatin

Objectives: Coenzyme Q10 (CoQ10, ubiquinone) stands among the safest supplements in the elderly to protect against cardiovascular disorders. Noteworthy, CoQ10 deficiency is common in many surviving stroke patients as they are mostly prescribed statins for the secondary prevention of stroke incidence lifelong. Accordingly, the current study aims to experimentally examine whether CoQ10 supplementation in animals receiving atorvastatin may affect acute stroke-induced injury.

Methods: Adult rats underwent transient middle cerebral artery occlusion after atorvastatin pretreatment (5 or 10 mg/ kg/day; po; 30 days) with or without CoQ10 (200 mg/kg/day). After 24 hours ischemic/reperfusion injury, animals were subjected to functional assessments followed by cerebral molecular and histological to detect inflammation, apoptosis and oxidative stress.

Results: Animals dosed with 10 mg/kg presented the worst neurological function and brain damage in the acute phase of stroke injury. CoQ10 supplementation efficiently improved functional deficit and cerebral infarction in all stroke animals, particularly those exhibiting statin toxicity. Such benefits were associated with remarkable anti-inflammatory and anti-apoptotic effects, based on the analyzed tumor necrosis factor-α, interleukin-6, Bax/Bcl2 and cleaved caspase 3/9 immunoblots. Importantly, our fluoro-jade staining data indicated CoQ10 may revert the stroke-induced neurodegeneration. No parallel alteration was detected in stroke-induced oxidative stress as determined by malondialdehyde and 8-oxo-2′-deoxyguanosine levels.

Discussion: These data suggest that all stroke animals may benefit from CoQ10 administration through modulating inflammatory and degenerative pathways. This study provides empirical evidence for potential advantages of CoQ10 supplementation in atorvastatin-receiving patients which may not shadow its antioxidant properties.
