Estatinas y mortalidad por influenza: revisión sistemática y meta-análisis / Statins and influenza mortality: systematic review and meta-analysis

INTRODUCCIÓN: Debido a sus propiedades antiinflamatorias, se ha planteado que el uso de las estatinas podría influir en la evolución de la infección por el virus de influenza. OBJETIVO: Evaluar el efecto de la terapia con estatinas sobre la mortalidad por influenza. MATERIAL y MÉTODOS: Se realizó un meta-análisis que incluyó estudios que evaluaron el uso de estatinas en pacientes con influenza e informaron los datos sobre mortalidad, después de buscar en las bases de datos PubMed/MEDLINE, Embase y Cochrane Controlled Trials. Se aplicó un modelo de efectos aleatorios. Se analizó el riesgo de sesgos y se desarrolló un análisis de sensibilidad. RESULTADOS: Se identificaron y se consideraron elegibles para el análisis ocho estudios (diez cohortes independientes), que incluyeron un total de 2.390.730 de pacientes. Un total de 1.146.995 de sujetos analizados recibieron estatinas mientras que 1.243.735 de sujetos formaron parte del grupo control. La terapia con estatinas se asoció con una menor mortalidad (OR: 0,66; IC 95%: 0,51-0,85). El análisis de sensibilidad mostró que los resultados fueron robustos. CONCLUSIONES: Nuestros datos sugieren que, en una población con influenza, el uso de estatinas se asoció con una reducción significativa de la mortalidad. Estos resultados deben confirmarse en futuros ensayos clínicos.

BACKGROUND: Due to their anti-inflammatory properties, it has been suggested that the use of statins could influence the evolution of influenza virus infection. AIM: To evaluate the effect of statin therapy on mortality from influenza. METHODS: A meta-analysis that included studies evaluating the use of statins in patients with influenza and reporting data on mortality, after searching the PubMed/MEDLINE, Embase, and Cochrane Controlled Trials databases, was performed. A random effects model was applied. The risk of bias was analyzed and a sensitivity analysis was performed. RESULTS: Eight studies (10 independent cohorts), which included a total of 2,390,730 patients, were identified and eligible for analysis. A total of 1,146,995 subjects analyzed received statins, while 1,243,735 subjects were part of the control group. Statin therapy was associated with lower mortality (OR: 0.66; 95% CI: 0.51-0.85). The sensitivity analysis showed that the results were robust. CONCLUSION: Our data suggest that, in a population with influenza, the use of statins was associated with a significant reduction in mortality. These results must be confirmed in future clinical trials.

Analysis of serum cholesterol, statins and atherosclerotic plaque in ruptured and unruptured intracranial aneurysm / Análise de colesterol sérico, estatina e placa aterosclerótica em aneurisma intracraniano roto e não roto

Introduction Intracranial aneurysm (IA) is a major healthcare concern. The use of statin to reduce serum cholesterol has shown evidence to reduce cardiovascular risk in various diseases, but the impact on IA has not been described. This study aims to determine whether statin use, and serum cholesterol levels interfere with outcomes after IA event. Methods A cohort of patients with IA was analyzed. Patients social and demographics data were collected.Modified Rankin scale (mRS) score after 6months of follow-up was the endpoint. The data regarding statins use, presence or not of atherosclerotic plaque in radiological images and serum cholesterol of 35 patients were included in our study. Linear regression models were used to determine the influence of those 6 variables in the clinical outcome. Results The prevalence of atherosclerotic plaque, high cholesterol and use of statins was 34.3%, 48.5%, and 14.2%, respectively. Statins and serum cholesterol did not impact the overall outcome,measured by mRS after 6 months (p>0.05), but did show different tendencies when separated by IA rupture status. Serum cholesterol shows na important association with rupture of aneurysm (p»0.0382). High cholesterol and use of statins show a tendency for worse outcome with ruptured aneurysm, and the opposite is true for unruptured aneurysm. The presence of atherosclerotic plaques was not related with worse outcomes. Conclusions Multiple and opposite mechanisms might be involved in the pathophysiology of IA. Ruptured aneurysms are associated with higher levels of serum cholesterol. Serum cholesterol and statins use were not correlated with worse outcomes, but further studies are important to clarify these relationships.

Introdução Aneurisma intracranial (AI) é uma grande preocupação para a saúde. Evidências apontam que o uso de estatina para reduzir o colesterol sérico diminui o risco cardiovascular em diversas doenças, mas o impacto em AI ainda não foi descrito. Este estudo almeja determinar se o uso de estatina e o nível sérico de colesterol interferem no desfecho clínico após a ocorrência de AIs. Métodos Uma coorte de pacientes com AI foi analisada. Os dados sociodemográficos dos pacientes foram coletados. Ao final de 6 meses de acompanhamento, aplicou-se a escala modificada de Rankin (mRS). Os dados sobre uso de estatina, existência de placa aterosclerótica em imagens radiológicas, e colesterol sérico de 35 pacientes foram incluídos no estudo. Modelos de regressão linear foram usados para determinar a influência dessas 6 variáveis nos desfechos clínicos. Resultados A prevalência de placa aterosclerótica, colesterol elevado, e uso de estatina foram respectivamente 34,3%, 48,5% e 14,2%. Estatina e colesterol sérico não impactaram nos desfechos medidos pela mRS em 6 meses (p > 0,05), mas mostraram diferentes tendências quando separados pelo estado de ruptura do AI. Colesterol sérico apresenta uma importante associação com ruptura de aneurisma (p » 0,0382). Colesterol elevado e uso de estatinas representam uma tendência a piores desfechos para aneurismas rompidos, e o oposto é verdade para os não rompidos. A presença de placa aterosclerótica não está relacionada com piores resultados. Conclusões Mecanismos múltiplos e opostos podem estar envolvidos na patofisio logia do AI. Aneurismas rompidos estão associados com maiores níveis de colesterol sérico. Colesterol sérico e estatinas não foram correlacionados com piores desfechos, mas mais estudos são importantes para clarificar a relação entre esses fatores

Reperfusion Strategies in Acute Myocardial Infarction: State of the Art

Abstract ST elevation myocardial infarction (STEMI) is a highly prevalent condition worldwide. Reperfusion therapy is strongly associated with the prognosis of STEMI and must be performed with a high standard of quality and without delay. A systematic review of different reperfusion strategies for STEMI was conducted, including randomized controlled trials that included major cardiovascular events (MACE), and systematic reviews in the last 5 years through the PRISMA ( Preferred Reporting Items for Systematic Reviews and Meta-Analysis) methodology. The research was done in the PubMed and Cochrane Central Register of Controlled Trials databases, in addition to a few manual searches. After the exclusion criteria were applied, 90 articles were selected for this review. Despite the reestablishment of IRA patency in PCI for STEMI, microvascular lesions occur in a significant proportion of these patients, which can compromise ventricular function and clinical course. Several therapeutic strategies - intracoronary administration of nicorandil, nitrates, melatonin, antioxidant drugs (quercetin, glutathione), anti-inflammatory substances (tocilizumab [an inhibitor of interleukin 6], inclacumab, P-selectin inhibitor), immunosuppressants (cyclosporine), erythropoietin and ischemic pre- and post-conditioning and stem cell therapy - have been tested to reduce reperfusion injury, ventricular remodeling and serious cardiovascular events, with heterogeneous results: These therapies need confirmation in larger studies to be implemented in clinical practice

Effectiveness of statin treatment strategies for primary prevention of cardiovascular diseases in a community-based Chinese population: A decision-analytic Markov model / 北京大学学报(医学版)

OBJECTIVE@#To evaluate the effectiveness of statin treatment strategies based on risk assessment for the primary prevention of cardiovascular diseases by the Western guidelines in a community-based Chinese population from economically developed areas using data from the Chinese electronic health records research in Yinzhou (CHERRY) study.@*METHODS@#A Markov model was used to evaluate the effectiveness of the following statin treatment strategies, including: (1) usual care without cardiovascular risk assessment(Strategy 0); (2) using the World Health Organization (WHO) non-laboratory-based risk charts with statin treatment for high-risk group (risk ≥ 20%) (Strategy 1); (3) using the WHO laboratory-based risk charts with statin treatment for high-risk group (risk ≥ 20%) (Strategy 2); and (4) using the Prediction for Atherosclerotic cardiovascular disease Risk in China (China-PAR) model with statin treatment for high-risk group (risk ≥ 10%, Strategy 3). According to the guidelines, adults in the medium-risk group received lifestyle intervention, and adults in the high-risk group received life-style intervention and statin treatment under these strategies. The Markov model simulated different strategies for ten years (cycles) using parameters from the CHERRY study, published data, meta-analyses and systematic reviews for Chinese. The number of cardiovascular events or deaths, as well as the number need to treat (NNT) with statin per cardiovascular event or death prevented, were calculated to compare the effectiveness of different strategies. One-way sensitivity analysis on the uncertainty of incidence rate of cardiovascular diseases, and probabilistic sensitivity analysis on the uncertainty of hazard ratios of interventions were conducted.@*RESULTS@#Totally 225 811 Chinese adults aged 40-79 years without cardiovascular diseases at baseline were enrolled. In contrast to the usual care without risk assessment-based statin treatment strategy, Strategy 1 using the WHO non-laboratory-based risk charts could prevent 3 482 [95% uncertainty interval (UI): 2 110-4 661] cardiovascular events, Strategy 2 using the WHO laboratory-based risk charts could prevent 3 685 (95%UI: 2 255-4 912) events, and Strategy 3 using the China-PAR model could prevent 3 895 (95%UI: 2 396-5 181) events. NNTs with statin per cardiovascular event prevented were 22 (95%UI: 14-54), 21 (95%UI: 14-52), and 27 (95%UI: 17-67), respectively. Strategy 3 could prevent more cardiovascular events, while Strategies 1 and 2 required fewer numbers need to treat with statin per cardiovascular event prevented. The results were consistent in the sensitivity analyses.@*CONCLUSION@#The statin treatment strategies based on risk assessment for the primary prevention of cardiovascular diseases recommended by the Western guidelines could achieve substantive health benefits in adults from developed areas of China. Using the China-PAR model for cardiovascular risk assessment could prevent more cardiovascular diseases while using the WHO risk charts seems more efficient.

Influence of ApoE gene polymorphisms on therapeutic effects of lipid-lowering statins among patients with ischemic cerebral infarction / 中华医学遗传学杂志

OBJECTIVE@#To assess the influence of apolipoprotein E (ApoE) gene polymorphisms on the therapeutic effect of lipid-lowering statins in patients with ischemic cerebral infarction.@*METHODS@#One hundred and six patients with ischemic cerebral infarction who orally took lipid-lowering statins for 3 months were enrolled. Changes in serum triacylglycerol (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) before and after the drug administration were analyzed. ApoE gene polymorphisms were detected by real-time fluorescent quantitative PCR, and genotypes of ApoE gene in patients with different effects were compared.@*RESULTS@#The detection rates for E2/E2, E2/E3, E3/E3, E2/E4 and E3/E4 genotypes were 0.94%, 11.32%, 63.21%, 1.89% and 22.64%, respectively. And the detection rates for E2, E3 and E4 alleles were 7.55%, 80.19% and 12.26%, respectively. Biochemical phenotypes included E2 type (13 cases, 12.26%), E3 type (69 cases, 65.09%) and E4 type (24 cases, 22.65%). Before administration, TG and TC of E2 type were the highest (P<0.05), but no significant difference was detected in HDL-C and LDL-C among the three phenotypes (P>0.05).Following the drug administration, TG, TC and LDL-C were decreased, while HDL-C was increased. HDL-C of E2 type was the highest, TC and LDL-C of E4 type were the highest (P<0.05). The E3/E3 ratio in low-efficiency group at admission was lower than that in the high-efficiency group, while the E3/E4 ratio was higher than that in the high-efficiency group (P<0.05). The proportion of E3 allele in low-efficiency group was lower than that in high-efficiency group, while the proportion of E4 allele was higher than that in high-efficiency group (P<0.05).@*CONCLUSION@#ApoE gene polymorphisms are closely correlated with the therapeutic effect of lipid-lowering statins in patients with ischemic cerebral infarction. The lipid-lowering effects are more significant in patients with E2 and E3 genotypes, but were poor in those with the E4 genotype. Personalized regimens should be applied.

A comparison of Statin treatment algorithms based on the ACC/AHA and Philippine Guidelines for primary prevention of Dyslipidemia in Statin-Naive Filipino patients / Journal of the ASEAN Federation of Endocrine Societies

Objectives@#This cross-sectional study evaluates the degree of agreement between the 2018 American College of Cardiology/American Heart Association (ACC/AHA2018) and 2020 Philippine Guideline (PG2020) treatment algorithms for the primary prevention of dyslipidemia among Filipinos.@*Methodology@#This review included 159 charts of statin-naive Filipinos who are 45-79 years old. Using risk profile and lipid measurements, statin treatment recommendation was determined through the PG2020 algorithm and ACC/AHA-ASCVD Risk Estimator Plus web application. The degree of agreement was measured by Cohen’s kappa statistic with the two algorithms as independent raters.@*Results@#A total of 159 patients were included in the final analysis. There was a slight agreement with a kappa coefficient of 0.209 or 4.4% (95% CI 0.078-0.340, p=0.003). Statin treatment was recommended in 69 out of 159 patients (43.4%) by the PG2020 overlapping with ACC/AHA2018 in 56 cases (81.2%). On the other hand, 109 cases (68.6%) were recommended for statin treatment by ACC/AHA2018 overlapping with PG2020 in only 51.4%. @*Conclusions@#The low degree of agreement between the two treatment algorithms highlights the key demographic and ethnic variations in dyslipidemia management necessitating outcome-based studies to translate these differences. Overestimation of ASCVD risk calculation in the ACC/AHA2018 and consideration of important, unique risk factors among Filipinos favors the applicability of the Philippine guideline.

Risk factors for potential drug-drug interactions of statins in patients with acute coronary syndrome

Abstract The aim of our study was to assess risk factors for potential drug-drug interactions (pDDIs) of statins across different phases of treatment of acute coronary syndrome (ACS) patients: from the point of first medical contact to the coronary angiography (first phase), after coronary angiography to the last day of hospitalization (second phase) and at discharge from hospital (third phase). This was a post hoc analysis of the data collected during the retrospective observational cohort study conducted at the Clinic for Cardiology of the Clinical Centre Kragujevac, Serbia. Patients prescribed statins were identified from the original study population: 156, 240 and 236 patients for the first, second and third phases, respectively. At least one statin pDDI was present in 113 (72.4%), 161 (67.1%) and 139 (58.9%) patients in the first, second and third phases, respectively. Heart failure, arrhythmias after ACS, CRP, triglycerides, length of hospitalization, number of prescribed drugs, antiarrhythmic drugs, and clopidogrel seem to increase the risk of statin pDDIs in at least one treatment phase. Physicians should be vigilant to the possibility of statin pDDIs in ACS patients who have factors that may increase their rate.

Influence of statins in metastatic castration-resistant prostate cancer patients treated with new antiandrogen therapies: a systematic review and meta-analysis

ABSTRACT Objective To evaluate whether the addition of statins to the new antiandrogens (enzalutamide or abiraterone) affects overall survival in patients with metastatic castration-resistant prostate cancer. Methods We searched studies in English language including the keywords statins, overall survival, and metastatic castration-resistant prostate cancer, at PubMed® (MEDLINE®), Embase and Cochrane databases. Results A total of 195 articles were initially identified, but only four met the inclusion criteria and were selected for the meta-analysis. A total of 955 patients, 632 on the new antiandrogens only group, and 323 on the new antiandrogens + statins group, were analyzed. In all four studies the combination therapy (new antiandrogens + statin) was well tolerated, regardless of which new antiandrogens were used. Neither the type of statin nor the doses and duration of use were well specified in the studies. The combination therapy in metastatic castration-resistant prostate cancer was associated with an overall survival improvement, and a 46% reduction in death (hazard ratio of 0.54; 95%CI 0.34-0.87; p<0.01) in multivariate analysis. Conclusion There seems to be a clinical benefit with the association of statins to the new antiandrogens in patients with metastatic castration-resistant prostate cancer, suggesting longer overall survival with no important collateral effect. However, due to fragility of the studies available in the literature, we are not yet capable of recommending this combination of drugs in the clinical practice. Further randomized prospective studies are warranted to confirm these beneficial outcomes.

Are statins a risk factor in patients with atherosclerosis? / ¿Son las estatinas un factor de riesgo en pacientes con aterosclerosis?

SUMMARY: Statins inhibit cholesterol synthesis, but also have other pleiotropic effects. There are indications that they affect macrophage survival trough the regulation of apoptosis. We analyzed 50 samples of aortic wall, selected based on statins in patients' therapy (n=25, Th-S group) or statin-free therapy (n=25, Th-nonS group). Each group had 5 samples of healthy aortic tissue, 10 samples of mild and 10 samples of severe atherosclerotic changes in aortic wall. Tissue was stained with hematoxylin-eosin and immunohistochemical methods (anti-Bcl-2 antibody). Presence of Bcl2-positive macrophages (Bcl-2+ MP) was determined semiquantitatively, and data were processed in Microsoft Excell and IMB SPSS 23 Statistics. 60 % of patients in the Th-S group had a mild increase of Bcl-2+ MP The use of statins leads to a significantly more frequent increase in Bcl2+ macrophages in the intima of the healthy aortic tissue. Analysis of all aortic samples with pathohistological diagnosis showed that statin therapy was statistically significantly more often leading to a markedly increased presence of Bcl-2+ MP. In the media, all samples of the Th-S group have a mild increase of Bcl-2+ MP, and in adventitia 40 % of patients. The use of statins more often leads to a markedly increased presence of Bcl-2+ MP in aortic tissue with diagnosed mild and severe atherosclerosis. In samples of severe atherosclerosis, statins lead to a markedly increased presence of Bcl-2+ MP in the parts of the plaque towards the intima and towards the media. Statins lead to an increased presence of Bcl-2+ macrophages, prolong their life, both in healthy and atherosclerotic altered aortic tissue. This indicates potentiation of inflammation and damage to the aortic wall, and calls into question the positive effect of statins on the aortic wall with atherosclerosis.

RESUMEN: Las estatinas inhiben la síntesis de colesterol, pero también tienen otros efectos pleiotrópicos. Hay indicios de que afectan la supervivencia de los macrófagos a través de la regulación de la apoptosis.Se analizaron 50 muestras de pared aórtica, seleccionadas en base a estatinas en tratamiento de pacientes (n=25, grupo Th-S) o en tratamiento libre de estatinas (n=25, grupo Th- nonS). Cada grupo tenía 5 muestras de tejido aórtico sano, 10 muestras de cambios ateroscleróticos leves y 10 muestras de cambios ateroscleróticos severos en la pared aórtica. El tejido se tiñó con hematoxilina-eosina y métodos inmunohistoquímicos (anticuerpo anti-Bcl-2). La presencia de macrófagos positivos para Bcl2 (Bcl- 2+ MP) se determinó semicuantitativamente y los datos se procesaron en Microsoft Excell e IMB SPSS 23 Statistics. El 60 % de los pacientes del grupo Th-S tuvo un aumento leve de Bcl-2+ MP. El uso de estatinas conduce a un aumento significativamente más frecuente de macrófagos Bcl2+ en la íntima del tejido aórtico sano. El análisis de todas las muestras aórticas con diagnóstico anatomopatológico mostró que la terapia con estatinas fue significativamente más frecuente desde el punto de vista estadístico, lo que condujo a una presencia marcadamente mayor de Bcl-2+ MP. En los medios, todas las muestras del grupo Th-S tienen un leve aumento de Bcl-2+ MP, y en adventicia en el 40 % de los pacientes. El uso de estatinas con mayor frecuencia conduce a una presencia marcadamente mayor de MP Bcl-2+ en el tejido aórtico con aterosclerosis leve y grave diagnosticada. En muestras de aterosclerosis severa, las estatinas conducen a una presencia aumentada de Bcl-2+ MP en las partes de la placa hacia la íntima y hacia la media. Las estatinas conducen a una mayor presencia de macrófagos Bcl-2+, prolongan su vida, tanto en tejido aórtico sano como aterosclerótico alterado. Esto indica la potenciación de la inflamación y el daño a la pared aórtica y pone en duda el efecto positivo de las estatinas en la pared aórtica con aterosclerosis.

Estudo do efeito de estatinas e antiplaquetários na evolução do infarto agudo do miocárdio: uma abordagem metabolômica multiplataform / Effect of statins and antiplatelets in the evolution of acute myocardium infarction: a multiplatform metabolomics approach

O infarto agudo do miocárdio (IAM) é a maior causa de mortalidade no mundo. A oclusão coronária determina a necrose completa de cardiomiócitos (células musculares cardíacas) durante as primeiras horas do IAM. Porém, mesmo após a perda de massa de miocárdio viável cessar, a região infartada pode se expandir ou contrair no decorrer das primeiras semanas, afetando o prognóstico dos pacientes. Alguns tratamentos podem auxiliar na recuperação e melhoria do prognóstico desses pacientes, como o uso de estatinas e antiplaquetários, que quando utilizados em conjunto, proporcionam efeitos sinérgicos. O presente estudo investigou e comparou, através da óptica da metabolômica global multiplataforma, tratamentos concomitantes de estatinas (sinvastatina ou rosuvastatina) e antiplaquetários bloqueadores do receptor de ADP (clopidogrel ou ticagrelor), em pacientes que sofreram IAM. Foram coletadas amostras de plasma e urina de cerca 40 pacientes tratados com clopidrogrel e sinvastatina ou ticagrelor e rosuvastatina no Hospital São Paulo em diferentes períodos (basal, 1 mês e 6 meses após IAM). Amostras de plasma (basal e 1 mês) foram analisadas por RPLC-MS nos modos de ionização positivo e negativo, GC-MS e CEMS. Amostras de urina (basal, 1 mês e 6 meses) foram analisadas por RPLC-MS no modo de ionização positivo e HILIC-MS nos modos de ionização positivo e negativo. A abordagem metabolomica global multiplataforma evidenciou alterações no metabolismo de diferentes vias pelos dois tratamentos. Os dois tratamentos proporcionaram um efeito pronunciado no metabolismo de diferentes lipídios, como glicerolipídios, esfingolipídios, glicerofosfolipídios e ácidos graxos, sendo que a combinação rosuvastatina e ticagrelor resultou num efeito mais acentuado. Já o tratamento com clopidogrel e sinvastatina alterou de maneira mais pronunciada o metabolismo de aminoácidos ramificados e de acilcarnitinas de cadeia curta. Observou-se ainda a alteração de possíveis biomarcadores relatados na literatura como associados a problemas cardiovasculares, como hipoxantina, ácido 2-hidroxibutírico, algumas espécies de ceramidas, fosfatidilcolinas e acilcarnitinas de cadeia curta

cute myocardium infarction (AMI) is the main mortality cause in the world. The coronary occlusion determines the complete necrosis of cardiomyocytes (cardiac muscle cells) during the first hours of AMI. However, even after the loss of viable myocardial mass ceases, the infarcted area may still expand or contract during the first weeks after AMI, affecting the patient prognosis. Some treatments may assist patient recovery and improve prognostic, such as statins and antiplatelets which, when combined, provide synergic effects. This study investigated and compared, by untargeted multiplatform metabolomics, simultaneous treatments of statins (simvastatin or rosuvastatin) and ADP receptor antagonist antiplatelets (clopidogrel or ticagrelor) in patients that suffered AMI. Plasma and urine samples from around 40 patients treated with clopidogrel and simvastatin or ticagrelor and rosuvastatin were collected in Hospital Sao Paulo at different time points (basal, 1 month, 6 months after AMI). Plasma samples (basal and 1 month) were analyzed by RPLC-MS in positive and negative ionization modes, GC-MS and CE-MS. Urine samples (basal, 1 month, 6 months) were analyzed by RPLC-MS in positive ionization mode and by HILIC-MS in positive and negative ionization modes. The untargeted multiplatform metabolomics approach has shown that different metabolic pathways have been altered by the two treatments. Both treatments had a profound impact on the metabolism of different lipids, such as glycerolipids, sphingolipids, glycerophospholipids, and fatty acids. However, the combined treatment using rosuvastatin and ticagrelor impacted the most the lipid pathways. On the other hand, clopidogrel and simvastatin treatment affected more intensily the branched chain amino acids and short chain acylcarnitines metabolisms. Reported biomarkers in the literature related to cardiovascular diseases were also observed in this study, such as hypoxanthine, 2-hydroxybutyric acid, some species of ceramides, phosphatidylcholines and short chain acylcarnitines

Efectividad clínica y radiográfica de las estatinas en el tratamiento de la periodontitis / Clinical and radiographic effectiveness of statins in the treatment of periodontitis

Introducción: La enfermedad periodontal es un padecimiento inflamatorio, infeccioso y multifactorial crónico, caracterizado por la inflamación de los tejidos blandos periodontales. En estadios avanzados (periodontitis), produce la destrucción progresiva de los tejidos duros periodontales, lo que conduce a la posterior pérdida de dientes, si esta no es tratada. Objetivo: Determinar la efectividad clínica y radiográfica de las estatinas en el tratamiento de la periodontitis. Métodos: Se realizó una búsqueda de la literatura hasta abril del 2019, en las bases de datos biomé dicas: PubMed, Embase, SciELO, Science Direct, Scopus, Sistema de información sobre literatura gris en Europa, Literatura Latinoamericana y del Caribe en Ciencias de la Salud, Google Académico y el Registro Central de Ensayos Clínicos Cochrane. Se definieron como criterios de selección de los estudios que fueran ensayos clínicos aleatorizados, con una antigüedad máxima de cinco años y que reportaran los efectos clínicos y radiográficos (profundidad al sondaje, nivel de inserción clínica, índice de placa, índice de sangrado, índice gingival, defecto intraóseo y profundidad del defecto) de las estatinas en el tratamiento de la periodontitis. Se analizó el riesgo de sesgo de los estudios por el Manual Cochrane de revisiones sistemáticas de intervenciones. Resultados: La estrategia de búsqueda arrojó 19 artículos, de los cuales el 100 por ciento reportó que había diferencia en la profundidad al sondaje, nivel de inserción clínica, índice de placa, índice de sangrado, índice gingival, defecto intraóseo y profundidad del defecto de las estatinas en el tratamiento de la periodontitis. Conclusiones: La literatura revisada sugiere que el uso de estatinas es efectivo, clínica y radiográficamente, en el tratamiento de la periodontitis(AU)

Introduction: Periodontal disease is a chronic multifactorial infectious inflammatory condition characterized by inflammation of soft periodontal tissue. In advanced stages (periodontitis) it causes progressive destruction of hard periodontal tissue, leading to eventual tooth loss if not treated. Objective: Determine the clinical and radiographic effectiveness of statins in the treatment of periodontitis. Methods: A search was carried out in the literature published until April 2019 in the biomedical databases PubMed, Embase, SciELO, Science Direct, Scopus, System for Information on Gray Literature in Europe, Latin American and Caribbean Health Sciences Literature, Google Scholar, and Cochrane Central Register of Clinical Trials. The following selection criteria were defined for the studies: randomized clinical trials published in the last five years and reporting on clinical and radiographic effects (probing depth, clinical insertion level, plaque index, bleeding index, gingival index, intraosseous defect and defect depth) of statins in the treatment of periodontitis. Bias risk analysis was based on the Cochrane manual of systematic reviews of interventions. Results: A total 19 papers were retrieved, of which 100 percent reported differences in the probing depth, clinical insertion level, plaque index, bleeding index, gingival index, intraosseous defect and defect depth of statins in the treatment of periodontitis. Conclusions: The literature review conducted suggests that the use of statins is clinically and radiographically effective in the treatment of periodontitis(AU)

Manejo de la hipercolesterolemia desde dos ángulos diferentes / Hypercholesterolemia management from two different points of view

RESUMEN La cardiopatía isquémica y los accidentes cerebrovasculares son la primera causa de muerte en el mundo. La enfermedad cardiovascular de origen ateroesclerótico es un problema internacional de salud, que constituye una carga social, sanitaria y económica. Se realizó un análisis de las principales guías internacionales sobre dislipoproteinemias y su manejo, como las de la Sociedad Europea de Cardiología y las del Colegio Americano de Cardiología/Asociación Americana del Corazón. También, de los principales artículos publicados en los últimos cinco años sobre el manejo de la hipercolesterolemia, de los cuales se tomaron 20 publicaciones en Medline, Google Académico y SciELO. Las mencionadas guías reúnen las recomendaciones de sus respectivas organizaciones y las combinan con nuevas. Ambas mantienen el uso de scores de riesgo y discrepan sobre la imagenología en la determinación del tratamiento, al igual que en el uso de drogas no estatinas. Se plantea que la mejor intervención para prevenir la enfermedad cardiovascular es la promoción de un estilo de vida saludable (AU).

ABSTRACT Ischemic cardiomyopathy and cerebrovascular stroke are the first causes of death in the world. Cardiovascular disease of atherosclerotic origins is an international health problem that is also a social, sanitary and economic burden. The authors analyzed the main international guidelines on dyslipoproteinemia, like the ones from the European Society of Cardiology and the American College of Cardiology/American Heart Association. They also considered the main articles published in the last five years on the management of hypercholesterolemia and chose 20 of them available in Medline, Google Scholar and SciELO. The before-mentioned guidelines gather the recommendations of their own organizations, and combine them with new ones. They both keep using risk scores on and differ on medical imaging determining the treatment, and also in the use of non-statin drugs. It is stated that the better intervention to prevent cardiovascular disease is the promotion of a healthy lifestyle (AU).

Uso de estatinas melhora a proteção cardiometabólica promovida pelo treinamento físico em ambiente aquático: Um ensaio clínico randomizado / Statin use improves cardiometabolic protection promoted by physical training in an aquatic environment: A Randomized Clinical Trial

Resumo Fundamento: O uso de estatinas destaca-se como a terapia mais frequentemente utilizada para o tratamento de dislipidemias e pode ser considerado a intervenção farmacológica mais eficiente para a redução da lipoproteína de baixa densidade (LDL). Por outro lado, o treinamento físico pode ser considerado uma estratégia não farmacológica eficiente e segura para promover melhorias no perfil lipídico. No entanto, não se sabe qual seria a influência das estatinas nas adaptações lipídicas decorrentes do treinamento aquático em populações com dislipidemia. Objetivos: Analisar a influência do uso de sinvastatina nas adaptações lipídicas decorrentes do treinamento aeróbico em meio aquático e de resistência em mulheres idosas com dislipidemia. Métodos: Sessenta e nove mulheres idosas (66,13 ± 5,13 anos), sedentárias e dislipidêmicas, tanto não usuárias quanto usuárias de sinvastatina (20 mg e 40 mg), foram randomizadas nos 3 grupos seguintes: treinamento aeróbico em meio aquático (WA), treinamento de força em meio aquático (WR) e grupo controle (GC). A duração total das intervenções, para todos os grupos experimentais, foi de 10 semanas, com 2 sessões semanais. As análises bioquímicas foram realizadas antes do início das intervenções e repetidas após o final do ensaio. Foram utilizadas equações de estimativa generalizada para comparar esses dados, estabelecendo α = 0,05. Resultados: Na análise por intenção de tratar, as participantes medicadas demonstraram uma redução de magnitude maior do colesterol total (CT) (−3,41 a −25,89 mg.dl−1; p = 0,038), LDL (−5,58 a −25,18 mg.dl−1; p = 0,007) e da relação CT/HDL (−0,37 a −0,61; p = 0,022) quando comparadas às participantes não medicadas, essa redução sendo estatisticamente significativa apenas no grupo WR. Conclusões: O uso de estatina incrementa as adaptações promovidas pelo treinamento físico aquático no CT, nos níveis de LDL e na relação CT/HDL, sendo mais pronunciado após WR.

Abstract Background: Statin use is highlighted as the most commonly utilized therapy for the treatment of dyslipidemias and can be considered as the most efficient pharmacological intervention for low-density lipoprotein (LDL) reduction. On the other hand, physical training can be considered an efficient and safe non-pharmacological strategy to promote improvements in lipid profile. However, the influence of statins on lipid adaptations arising from water-based training in populations with dyslipidemia is not known. Objectives: To analyze the influence of simvastatin use on lipid adaptations arising from water-based aerobics and resistance training in elderly women with dyslipidemia. Methods: Sixty-nine elderly (66.13 ± 5.13 years), sedentary, and dyslipidemic women, both non-users and users of simvastatin (20 mg and 40 mg), were randomized into the following 3 groups: water-based aerobic training (WA), water-based resistance training (WR), and control group (CG). Total duration of interventions, for all experimental groups consisted of 10 weeks, with 2 weekly sessions. Biochemical analyses were performed before the beginning of the interventions and repeated after the end of the trial. Generalized estimating equations were used to compare these data, setting α = 0.05. Results: In intention-to-treat analysis, the medicated participants obtained a greater magnitude of decrease in total cholesterol (TC) (−3.41 to −25.89 mg.dl−1; p = 0.038), LDL (−5.58 to −25.18 mg.dl−1; p = 0.007) and TC/HDL ratio (−0.37 to −0.61; p = 0.022) when compared to the non-medicated participants, and this decrease was statistically significant only in the WR group. Conclusions: Statin use enhances the adaptations promoted by water-based physical training in CT, LDL levels, and CT/HDL ratio, and it is more pronounced after WR.
