BMJ (Clinical Research Ed.) Oct 2023To compare the long term efficacy and safety of rosuvastatin with atorvastatin treatment in adults with coronary artery disease. (Randomized Controlled Trial)
Randomized Controlled Trial
OBJECTIVE
To compare the long term efficacy and safety of rosuvastatin with atorvastatin treatment in adults with coronary artery disease.
DESIGN
Randomised, open label, multicentre trial.
SETTING
12 hospitals in South Korea, September 2016 to November 2019.
PARTICIPANTS
4400 adults (age ≥19 years) with coronary artery disease.
INTERVENTIONS
Participants were assigned to receive either rosuvastatin (n=2204) or atorvastatin (n=2196) using 2×2 factorial randomisation.
MAIN OUTCOME MEASURES
The primary outcome was a three year composite of all cause death, myocardial infarction, stroke, or any coronary revascularisation. Secondary outcomes were safety endpoints: new onset diabetes mellitus; hospital admissions due to heart failure; deep vein thrombosis or pulmonary thromboembolism; endovascular revascularisation for peripheral artery disease; aortic intervention or surgery; end stage kidney disease; discontinuation of study drugs owing to intolerance; cataract surgery; and a composite of laboratory detected abnormalities.
RESULTS
4341 of the 4400 participants (98.7%) completed the trial. Mean daily dose of study drugs was 17.1 mg (standard deviation (SD) 5.2 mg) in the rosuvastatin group and 36.0 (12.8) mg in the atorvastatin group at three years (P<0.001). The primary outcome occurred in 189 participants (8.7%) in the rosuvastatin group and 178 (8.2%) in the atorvastatin group (hazard ratio 1.06, 95% confidence interval 0.86 to 1.30; P=0.58). The mean low density lipoprotein (LDL) cholesterol level during treatment was 1.8 mmol/L (SD 0.5 mmol/L) in the rosuvastatin group and 1.9 (0.5) mmol/L in the atorvastatin group (P<0.001). The rosuvastatin group had a higher incidence of new onset diabetes mellitus requiring initiation of antidiabetics (7.2% 5.3%; hazard ratio 1.39, 95% confidence interval 1.03 to 1.87; P=0.03) and cataract surgery (2.5% 1.5%; 1.66, 1.07 to 2.58; P=0.02). Other safety endpoints did not differ between the two groups.
CONCLUSIONS
In adults with coronary artery disease, rosuvastatin and atorvastatin showed comparable efficacy for the composite outcome of all cause death, myocardial infarction, stroke, or any coronary revascularisation at three years. Rosuvastatin was associated with lower LDL cholesterol levels but a higher risk of new onset diabetes mellitus requiring antidiabetics and cataract surgery compared with atorvastatin.

Randomized Controlled Trial
IMPORTANCE
In patients with coronary artery disease, some guidelines recommend initial statin treatment with high-intensity statins to achieve at least a 50% reduction in low-density lipoprotein cholesterol (LDL-C). An alternative approach is to begin with moderate-intensity statins and titrate to a specific LDL-C goal. These alternatives have not been compared head-to-head in a clinical trial involving patients with known coronary artery disease.
OBJECTIVE
To assess whether a treat-to-target strategy is noninferior to a strategy of high-intensity statins for long-term clinical outcomes in patients with coronary artery disease.
DESIGN, SETTING, AND PARTICIPANTS
A randomized, multicenter, noninferiority trial in patients with a coronary disease diagnosis treated at 12 centers in South Korea (enrollment: September 9, 2016, through November 27, 2019; final follow-up: October 26, 2022).
INTERVENTIONS
Patients were randomly assigned to receive either the LDL-C target strategy, with an LDL-C level between 50 and 70 mg/dL as the target, or high-intensity statin treatment, which consisted of rosuvastatin, 20 mg, or atorvastatin, 40 mg.
MAIN OUTCOMES AND MEASURES
Primary end point was a 3-year composite of death, myocardial infarction, stroke, or coronary revascularization with a noninferiority margin of 3.0 percentage points.
RESULTS
Among 4400 patients, 4341 patients (98.7%) completed the trial (mean [SD] age, 65.1 [9.9] years; 1228 females [27.9%]). In the treat-to-target group (n = 2200), which had 6449 person-years of follow-up, moderate-intensity and high-intensity dosing were used in 43% and 54%, respectively. The mean (SD) LDL-C level for 3 years was 69.1 (17.8) mg/dL in the treat-to-target group and 68.4 (20.1) mg/dL in the high-intensity statin group (n = 2200) (P = .21, compared with the treat-to-target group). The primary end point occurred in 177 patients (8.1%) in the treat-to-target group and 190 patients (8.7%) in the high-intensity statin group (absolute difference, -0.6 percentage points [upper boundary of the 1-sided 97.5% CI, 1.1 percentage points]; P < .001 for noninferiority).
CONCLUSIONS AND RELEVANCE
Among patients with coronary artery disease, a treat-to-target LDL-C strategy of 50 to 70 mg/dL as the goal was noninferior to a high-intensity statin therapy for the 3-year composite of death, myocardial infarction, stroke, or coronary revascularization. These findings provide additional evidence supporting the suitability of a treat-to-target strategy that may allow a tailored approach with consideration for individual variability in drug response to statin therapy.

5-Fluorouracil (5-Fu) is the preferred drug in colorectal cancer treatment. Although 5-Fu treatment contributes to the increase in survival rates, long-term use of 5-Fu causes severe intestinal damage, eventually decreasing long-term survival. There is no standardtreatmentfor intestinal damage induced by 5-Fu. Our previous study found that 5-Fu-induced intestinal damage was connected to an increase in senescent cells, and antiaging drugs could relieve some adverse side effects caused by 5-Fu. Hence, it is essential to discover novel, potential antiaging therapeutic drugs for 5-Fu side effect treatment. According to the current study, Atorvastatincalcium (Ator) alleviated cellular senescence in human intestinal epithelial cells (HUVECs) and human umbilical vein endothelial cells (HIECs) caused by oxidative stress and 5-Fu. 5-Fu resulted in an increase in SA-β-Gal-positive cells, synchronously increased expression of aging-related proteins (p16), aging-related genes (p53, p21), and the senescence-associated secretory phenotype (SASP: IL-1β, IL-6, TNF-α), while Atorvastatincalcium (Ator) reversed the increase in these indicators. In the BALB/c mouse model, we confirmed that intestinal damage caused by 5-Fu is related to the increase in senescent cells and drug-induced inflammation, with the therapeutic effects of Ator. In addition, Ator increased the sensitivity of 5-Fu to chemotherapy in vitro and in vivo. Combination therapy significantly reduced HCT116 cell viability. Furthermore, Ator and 5-Fu present a cooperative effect on preventing the growth of tumors in CRC xenograft nude mice. In conclusion, our study demonstrates the value of Ator for treating intestinal damage. Moreover, Ator combined with 5-Fu increased the antitumor ability in CRC cells. Additionally, we provide a novel therapeutic protocol for CRC.

Meta-Analysis
Alzheimer's disease is characterized by the presence of extraneuronal amyloid plaques composed of amyloid-beta (Aβ) fibrillar aggregates in the brains of patients. In mouse models, it has previously been shown that atorvastatin (Ator), a cholesterol-lowering drug, has some reducing effect on the production of cerebral Aβ. A meta-analysis on humans showed moderate effects in the short term but no improvement in the Alzheimer's Disease Assessment Scale-Cognitive Subscale behavioral test. Here, we explore a potential direct effect of Ator on Aβ42 aggregation. Using NMR-based monomer consumption assays and CD spectroscopy, we observed a promoting effect of Ator in its original form (Ator-calcium) on Aβ42 aggregation, as expected because of the presence of calcium ions. The effect was reversed when applying a CaCO-based calcium ion scavenging method, which was validated by the aforementioned methods as well as thioflavin-T fluorescence assays and transmission electron microscopy. We found that the aggregation was inhibited significantly when the concentration of calcium-free Ator exceeded that of Aβ by at least a factor of 2. The H-N heteronuclear single quantum correlation and saturation-transfer difference NMR data suggest that calcium-free Ator exerts its effect through interaction with the KLVF binding site on the Aβ peptide via its aromatic rings as well as hydroxyl and methyl groups. On the other hand, molecular dynamics simulations confirmed that the increasing concentration of Ator is necessary for the inhibition of the conformational transition of Aβ from an α-helix-dominant to a β-sheet-dominant structure.

Randomized Controlled Trial
BACKGROUND
Although lithium is considered the gold-standard treatment for bipolar disorder (BD), it is associated with a variety of major endocrine and metabolic side effects, including parathyroid hormone (PTH) dependent hypercalcemia. Aside from surgery and medication discontinuation, there are limited treatments for hypercalcemia. This paper will assess data from a randomized controlled trial (RCT).
METHODS
This is a secondary analysis of an RCT that explored the effects of atorvastatin (n = 27) versus placebo (n = 33) on lithium-induced nephrogenic diabetes insipidus (NDI) in patients with BD and major depressive disorder (MDD) using lithium (n = 60), over a 12-week period. This secondary analysis will explore serum calcium levels and thyroid stimulating hormone (TSH) measured at baseline, week 4, and week 12.
RESULTS
At 12-weeks follow-up while adjusting results for baseline, linear regression analyses found that corrected serum calcium levels were significantly lower in the treatment group (mean (M) = 2.30 mmol/L, standard deviation (SD) = 0.07) compared to the placebo group (M = 2.33 mmol/L, SD = 0.07) (β = - 0.03 (95% C.I.; - 0.0662, - 0.0035), p = 0.03) for lithium users. There were no significant changes in TSH.
CONCLUSION
In lithium users with relatively normal calcium levels, receiving atorvastatin was associated with a decrease in serum calcium levels. Although exciting, this is a preliminary finding that needs further investigation with hypercalcemic patients. Future RCTs could examine whether atorvastatin can treat PTH dependent hypercalcemia due to lithium and other causes.

Electroporation is influenced by the features of the targeted cell membranes, e.g., the cholesterol content and the surface tension of the membrane. The latter is eventually affected by the organization of actin fibers. Atorvastatin is a statin known to influence both the cholesterol content and the organization of actin. This work analyzes the effects of the latter on the efficacy of electroporation of cancer cells. In addition, herein, electroporation was combined with calcium chloride (CaEP) to assess as well the effects of the statin on the efficacy of electrochemotherapy. Cholesterol-rich cell lines MDA-MB231, DU 145, and A375 underwent (1) 48 h preincubation or (2) direct treatment with 50 nM atorvastatin. We studied the impact of the statin on cholesterol and actin fiber organization and analyzed the cells' membrane permeability. The viability of cells subjected to PEF (pulsed electric field) treatments and CaEP with 5 mM CaCl was examined. Finally, to assess the safety of the therapy, we analyzed the N-and E-cadherin localization using confocal laser microscopy. The results of our investigation revealed that depending on the cell line, atorvastatin preincubation decreases the total cholesterol in the steroidogenic cells and induces reorganization of actin nearby the cell membrane. Under low voltage PEFs, actin reorganization is responsible for the increase in the electroporation threshold. However, when subject to high voltage PEF, the lipid composition of the cell membrane becomes the regulatory factor. Namely, preincubation with atorvastatin reduces the cytotoxic effect of low voltage pulses and enhances the cytotoxicity and cellular changes induced by high voltage pulses. The study confirms that the surface tension regulates of membrane permeability under low voltage PEF treatment. Accordingly, to reduce the unfavorable effects of preincubation with atorvastatin, electroporation of steroidogenic cells should be performed at high voltage and combined with a calcium supply.

AIM
In this study, the protective effects of atorvastatin calcium (AC) on nerve cells and cognitive improvement and were investigated by establishing cell models and vascular dementia (VD) rat models.
BACKGROUND
VD is a neurodegenerative disease characterized by cognitive deficits caused by chronic cerebral hypoperfusion. AC has been studied for its potential to cure VD but its efficacy and underlying mechanism are still unclear.
OBJECTIVE
The mechanism of action of AC on cognitive deficits in the early stages of VD is unclear. Here, the 2-vessel occlusion (2-VO) model and the hypoxia/reoxygenation (H/R) cell model was established to investigate the function of AC in VD.
METHODS
The spatial learning and memory abilities of rats were detected by the Morris method. The IL-6, tumour necrosis factor-α (TNF-α), malondialdehyde (MDA) and superoxide dismutase (SOD) in cell supernatant was tested by ELISA kits. After behavioural experiments, rats were anaesthetized and sacrificed, and their brains were extracted. One part was immediately fixed in 4% paraformaldehyde for H&E, Nissl, and immunohistochemical analyses, and the other was stored in liquid nitrogen. All data were shown as mean ± SD. Statistical comparison between the two groups was performed by Student's t-test. A two-way ANOVA test using GraphPad Prism 7 was applied for escape latency analysis and the swimming speed test. The difference was considered statistically significant at p < 0.05.
RESULTS
AC decreased apoptosis, increased autophagy, and alleviated oxidative stress in primary hippocampal neurons. AC regulated autophagy-related proteins by western blotting. VD mice improved cognitively in the Morris water maze. Spatial probing tests showed that VD animals administered AC had considerably longer swimming times to the platform than VD rats. H&E and Nissl staining showed that AC reduces neuronal damage in VD rats. Western blot and qRT-PCR indicated that AC in VD rats inhibited Bax and promoted LC3-II, Beclin-1, and Bcl-2 in the hippocampus region. AC also improves cognition via the AMPK/mTOR pathway.
CONCLUSION
This study found that AC may relieve learning and memory deficits as well as neuronal damage in VD rats by changing the expression of apoptosis/autophagy-related genes and activating the AMPK/mTOR signalling pathway in neurons.

Randomized Controlled Trial
The study was designed to compare Rosuvastatin with Atorvastatin in terms of their efficacy to reduce low-density lipoproteins (LDL-C) in patients with type 2 diabetes mellitus. For this purpose, a cross-sectional analytical study was conducted in the OPD of Nishtar Medical Hospital, Multan, for six months. The study enrolled 66 patients who were consecutively allocated for double-blind therapy with 10mg Atorvastatin (n = 33) and 10mg Rosuvastatin (n = 33) for one month. The doses titration was carried up to four months in certain patients who failed to achieve 1998 European LDL-C level in the first month. A significant number of patients who were given 10mg Rosuvastatin matched the 1998 LDL-C goal in compared to the patients with 10mg dose of atorvastatin at one month (51% vs 46%, p< 0.0001) and at four months (94% vs 88%, p<0.05). Conclusively, Rosuvastatin was significantly more efficacious than Atorvastatin in its ability to reduce LDL-C.

Review
Atorvastatin calcium is an HMG-coenzyme A (CoA) reductase inhibitor that was approved by the Food and Drug Administration on December 17, 1996. Like other such agents, it inhibits the action of HMG-CoA reductase and thereby decreases endogenous cholesterol synthesis, leading to a decrease in circulating low-density lipoprotein cholesterol. In addition to its effect on lipoprotein profile, atorvastatin reduces triglycerides to a greater extent than other HMG-CoA reductase inhibitors. These actions occur in a dose-dependent fashion. The adverse effect profile is similar to that of other agents in this class. Indications for atorvastatin include primary hypercholesterolemia as well as other lipid disorders.
