ABSTRACT

Abstract Background: Different strategies have been proposed for the cardiovascular risk management of patients with psoriasis. Objective: To estimate the cardiovascular risk and evaluate two cardiovascular prevention strategies in patients with psoriasis, analyzing which proportion of patients would be candidates to receive statin therapy. Methods: A retrospective cohort was selected from a secondary database. All patients >18 years with psoriasis without cardiovascular disease or lipid-lowering treatment were included. The atherosclerotic cardiovascular disease calculator (2018 American College of Cardiology/American Heart Association guidelines) and the Systematic Coronary Risk Evaluation risk calculator (2016 European Society of Cardiology/European Society of Atherosclerosis guidelines) were calculated. The SCORE risk value was adjusted by a multiplication factor of 1.5. The recommendations for the indication of statins suggested by both guidelines were analyzed. Results: A total of 892 patients (mean age 59.9 ± 16.5 years, 54.5% women) were included. The median atherosclerotic cardiovascular disease calculator and Systematic Coronary Risk Evaluation values were 13.4% (IQR 6.1-27.0%) and 1.9% (IQR 0.4-5.2), respectively. According to the atherosclerotic cardiovascular disease calculator, 20.1%, 11.0%, 32.9%, and 36.4% of the population was classified at low, borderline, moderate, or high risk. Applying the Systematic Coronary Risk Evaluation, 26.5%, 42.9%, 20.8%, and 9.8% of patients were stratified as having low, moderate, high, or very high risk, respectively. The proportion of subjects with statin indication was similar using both strategies: 60.1% and 60.9% for the 2018 American College of Cardiology/American Heart Association and 2016 European Society of Cardiology/European Society of Atherosclerosis guidelines, respectively. Study limitations: This was a secondary database study. Data on the severity of psoriasis and pharmacological treatments were not included in the analysis. Conclusion: This population with psoriasis was mostly classified at moderate-high risk and the statin therapy indication was similar when applying the two strategies evaluated.

ABSTRACT

ABSTRACT Atheroembolic renal disease (AERD) is a kidney manifestation of atherosclerosis as a systemic disease. AERD is defined as a renal impairment secondary to embolization of cholesterol crystals with consequent occlusion of renal vascularization. The current case report describes one patient with multiple risk factors but without any inciting event history who presents a very atypical clinical course of a severe and massive atheroembolic disease that developed spontaneously and silently.


RESUMO A doença renal ateroembólica (DRAE) é uma manifestação renal da aterosclerose enquanto patologia sistêmica. A DRAE é definida como uma disfunção renal secundária à embolização de cristais de colesterol seguida da oclusão da vascularização renal. O presente relato descreve o caso de um paciente com vários fatores de risco, porém sem um evento precipitante, que se apresentou com um curso clínico bastante atípico de doença ateroembólica grave de evolução espontânea e silenciosa.

ABSTRACT

Prevention and treatment of dyslipidemia should therefore be considered as an integral part of individual cardiovascular prevention interventions, which should be addressed primarily to those at higher risk who will benefit most. Statins are the most commonly used options for the pharmacologic treatment of dyslipidemia. In recent decades, numerous clinical trials have demonstrated the efficacy of these drugs to reduce cardiovascular mortality and major non-fatal atherothrombotic events in heterogeneous populations through both primary and secondary prevention. This group of drugs is part of the recommendations of both US and European guidelines, and should be prescribed to all patients who have already had a cardiovascular event and have no specific contraindication. However, a large percentage of patients that would benefit from a statin treatment do not receive them, have been prescribed a low dose or for a limited time. (AU)

ABSTRACT

Statins are a widely prescribed class of medications that inhibit similar pathways as the anti-resorptive bisphosphonate drugs. Statins target the mevalonate pathway by blocking HMG-CoA reductase. Several recent meta-analyses concluded statins are osteoprotective in the general population. Here we present current literature exploring the mechanisms underlying the putative osteoprotective effects of statins. We also review recent clinical studies, ranging from observational cohort studies to randomized clinical trials, testing the effect of statins on bone health in various populations. (AU)


Las estatinas son un grupo de drogas prescriptas en forma habitual, con la capacidad de bloquear vías de señalización similares a las inhibidas por los amino-bisfosfonatos. Las estatinas inhiben la vía del mevalonato, a través del bloqueo de diferentes enzimas. Varios metaanálisis recientes llevaron a la conclusión de que las estatinas tienen capacidad osteoprotectora en la población general. En esta revisión presentamos la literatura actual describiendo los mecanismos que subyacen en el potencial efecto osteoprotector de las estatinas, como así también estudios observacionales y clínicos aleatorizados sobre el efecto de estatinas en la salud ósea en diversas poblaciones.

ABSTRACT

PURPOSE: The 2013 American College of Cardiology (ACC)/American Heart Association (AHA) cholesterol management guidelines advocate the use of statin treatment for prevention of cardiovascular disease. We aimed to assess the usefulness of coronary artery calcium (CAC) for stratifying potential candidates of statin use among asymptomatic Korean individuals. MATERIALS AND METHODS: A total of 31375 subjects who underwent CAC scoring as part of a general health examination were enrolled in the current study. Statin eligibility was categorized as statin recommended (SR), considered (SC), and not recommended (SN) according to ACC/AHA guidelines. Cox regression analysis was employed to estimate hazard ratios (HR) with 95% confidential intervals (CI) after stratifying the subjects according to CAC scores of 0, 1–100, and >100. Number needed to treat (NNT) to prevent one mortality event during study follow up was calculated for each group. RESULTS: Mean age was 54.4±7.5 years, and 76.3% were male. During a 5-year median follow-up (interquartile range; 3–7), there were 251 (0.8%) deaths from all-causes. A CAC >100 was independently associated with mortality across each statin group after adjusting for cardiac risk factors (e.g., SR: HR, 1.60; 95% CI, 1.07–2.38; SC: HR, 2.98; 95% CI, 1.09–8.13, and SN: HR, 3.14; 95% CI, 1.08–9.17). Notably, patients with CAC >100 displayed a lower NNT in comparison to the absence of CAC or CAC 1–100 in SC and SN groups. CONCLUSION: In Korean asymptomatic individuals, CAC scoring might prove useful for reclassifying patient eligibility for receiving statin therapy based on updated 2013 ACC/AHA guidelines.

ABSTRACT

PURPOSE: Erlotinib-gemcitabine combined chemotherapy is considered as the standard treatment for unresectable pancreatic cancer. This study aimed to determine the clinical factors associated with response to this treatment. MATERIALS AND METHODS: This retrospective study included 180 patients with unresectable pancreatic cancer who received ≥2 cycles of gemcitabine-erlotinib combination therapy as first-line palliative chemotherapy between 2006 and 2014. "Long-term response" was defined as tumor stabilization after >6 chemotherapy cycles. RESULTS: The median progression-free survival (PFS) and overall survival (OS) were 3.9 and 8.1 months, respectively. On univariate analysis, liver metastasis (p=0.023) was negatively correlated with long-term response. Locally advanced stage (p=0.017), a history of statin treatment (p=0.01), and carcinoembryonic antigen levels <4.5 (p=0.029) had a favorable effect on long-term response. On multivariate analysis, a history of statin treatment was the only independent favorable factor for long-term response (p=0.017). Prognostic factors for OS and PFS were significantly correlated with liver metastasis (p=0.031 and 0.013, respectively). A history of statin treatment was also significantly associated with OS after adjusting for all potential confounders (hazard ratio, 0.48; 95% confidence interval, 0.26-0.92; p=0.026). CONCLUSION: These results suggest that statins have a favorable effect on "long-term response" to gemcitabine-erlotinib chemotherapy in unresectable pancreatic cancer patients. Statins may have a chemoadjuvant role in stabilizing long-term tumor growth.

ABSTRACT

El asma bronquial extrínseca se origina por una reacción inmunológica de hipersensibilidad tipo I, desencadenada principalmente por alérgenos ambientales. Clásicamente, la respuesta inmune mediada por células T CD4+ con perfil Th2 determina las principales características de esta enfermedad, con la infiltración de eosinófilos y basófilos que median la inflamación crónica de las vías aéreas. Se ha observado que las células T reguladoras pueden actuar como moduladores endógenos durante los procesos asmáticos, controlando la exacerbación de las crisis y disminuyendo el daño tisular. Aunque los glucocorticoides son el principal tratamiento para el asma, solo alivian temporalmente los síntomas y se asocian con efectos adversos y aparición de resistencia, lo cual ha incentivado el desarrollo de alternativas terapéuticas que modulen la respuesta inmune y controlen la inflamación crónica. Recientemente, se ha postulado que las estatinas podrían ser una alternativa promisoria para disminuir la respuesta inflamatoria y disminuir la morbilidad asociada a esta enfermedad, debido a su gran potencial inmunomodulador, entre los que se destaca la inducción de células T reguladoras(AU)


Extrinsic asthma is caused by an immunological type I hypersensitivity reaction triggered mainly by environmental allergens. Usually, immune response mediated mainly by CD4 + T cells with Th2 profile determines the main features of extrinsic asthma, including infiltration of eosinophils and basophils that mediate chronic inflammation of the airways. It has been observed that regulatory T cells may act as endogenous modulators during asthmatic processes, controlling crisis exacerbation and decreasing tissue damage. Although glucocorticoids are the main treatment for asthma, these only relieve symptoms temporarily and are associated with adverse effects and development of resistance, which has encouraged the development of alternative therapies that modulate the immune response and control chronic inflammation. Recently, it has been postulated that statins may be a promising alternative to reduce the inflammatory response and decrease the morbidity associated with this disease, due to its great immunomodulator potential, especially in the induction of regulatory T cells(AU)

ABSTRACT

ABSTRACT CONTEXT AND OBJECTIVE: To evaluate predictors of changes in lipid parameters consisting of LDL-C (low-density lipoprotein cholesterol), TC (total cholesterol) and non-HDL-C (non-high density lipoprotein cholesterol) among primary care patients. DESIGN AND SETTING: Retrospective study conducted on family medicine patients. METHODS: Demographic features and other clinically relevant information were abstracted from medical records. The primary outcome was the difference in LDL-C level from initial testing to the index test. Secondary outcomes were the changes in TC and non-HDL-C levels between two measurements. RESULTS: Three hundred and eleven participants were included in the final secondary analysis. Multiple linear regression revealed that male patients (β = 4.97, P = 0.040), diabetes (β = 9.75, P = 0.003) and higher LDL-C levels at baseline (β = 0.35, P < 0.001) were positively associated with LDL variance, whereas longer time period (β = -0.15, P = 0.045) and familial hypercholesterolemia history (β = -7.56, P = 0.033) were negatively associated. Male patients (β = 8.45, P = 0.002), DM (β = 9.26, P = 0.011), higher TC levels at baseline (β = 0.35, P < 0.001) and taking statins (β = 7.31, P = 0.023) were positively associated with TC variance, whilst longer time period (β = -0.183, P = 0.031) and familial hypercholesterolemia (β = -10.70, P = 0.008) were negatively associated. CONCLUSION: In the present study, patients who were male, on statin treatment, diagnosed with diabetes and had higher baseline lipid values were more likely associated with better lipid outcomes at future testing.


RESUMO CONTEXTO E OBJETIVO: Avaliar preditores de alterações nos parâmetros lipídicos que consistem em LDL-C (colesterol de lipoproteína de baixa densidade), TC (colesterol total) e não HDL-C (não colesterol de lipoproteína de alta densidade) entre os pacientes de cuidados primários. TIPO DE ESTUDO E LOCAL: Estudo retrospectivo realizado em pacientes de medicina familiar. MÉTODOS: Aspectos demográficos e outras informações clinicamente relevantes foram extraídos dos prontuários médicos. O desfecho primário foi a diferença de nível de LDL-C entre os exames iniciais e o exame índice. Os desfechos secundários foram as mudanças dos níveis de TC e não HDL-C entre as duas medidas. RESULTADOS: Trezentos e onze participantes foram incluídos na análise secundária final. Regressão linear múltipla revelou que os pacientes do sexo masculino (β = 4,97, P = 0,040), diabetes (DM) (β = 9,75, P = 0,003) e níveis de LDL mais elevados no início do estudo (β = 0,35, P < 0,001) foram associados positivamente com variância LDL, enquanto longo período de tempo (β = -0,15, P = 0,045) e história hipercolesterolemia familiar (β = -7,56, P = 0,033) foram associados negativamente. Pacientes do sexo masculino (β = 8,45, P = 0,002), com DM (β = 9,26, P = 0,011), níveis elevados de CT na linha de base (β = 0,35, P < 0,001) e tomar estatinas (β = 7,31, P = 0,023) associaram-se positivamente com a variância TC, enquanto longo período de tempo (β = -0,183, P = 0,031), hipercolesterolemia familiar (β = -10,70, P = 0,008) foram associados negativamente. CONCLUSÕES: No presente estudo, os pacientes que eram do sexo masculino, em tratamento com estatinas, com diagnóstico de DM e que tinham valores lipídicos basais mais elevados foram mais provavelmente associados a melhores resultados de lipídios em testes futuros.

ABSTRACT

Objetivos: Describir los cambios del estado clínico periodontal de pacientes según el consumo sistémico de estatinas por indicación del cardiólogo. Material y método Se realizó un estudio descriptivo en el cual se reclutaron pacientes con periodontitis crónica derivados desde cardiología de la Clínica Dávila. Un grupo de ellos iniciaría terapia de estatinas. Se realizaron mediciones clínicas periodontales de profundidad al sondaje (PS), nivel de inserción clínico, índice de sangrado, área de superficie periodontal inflamada, e índice gingival, al inicio (antes de comenzar la terapia de estatinas) y 6 meses después. Los datos fueron analizados utilizando estadística descriptiva. Resultados Diez pacientes participaron del estudio, 5 con indicación de estatinas. El grupo con estatinas en comparación con el grupo sin estatinas presentó una disminución en promedio: de PS (0,4 mm versus 0,13 mm); porcentaje de sitios con PS > 5 mm (4,16 por ciento versus 1,09 por ciento); de nivel de inserción clínico (0,5 mm versus 0,2 mm), índice de sangrado (27,16 por ciento versus 8,8 por ciento) y área de superficie periodontal inflamada (305,68 mm2 versus 121,35). Conclusiones Estos resultados sugieren que pacientes con periodontitis crónica podrían obtener beneficios de la terapia sistémica con estatinas. Se requiere de estudios clínicos con asignación aleatoria y el óptimo tamaño muestral que comprueben el efecto e impacto de las estatinas sobre el estado periodontal.


Objective: To describe changes in periodontal clinical status of patients according to systemic statin use prescribed by a cardiologist. Material and methods A descriptive study was performed on patients with chronic periodontitis referred from the Department of Cardiovascular Diseases of Dávila Clinic. A group of them began statin therapy. Clinical measurements of periodontal probing depth (PD), clinical attachment level, bleeding index, periodontal inflamed surface area, and gingival index, were performed at baseline (before starting statin therapy) and 6 months later. Data were analyzed using descriptive statistics. Results A total of 10 patients participated in the study, and five of them received statin therapy. The statin group compared to the group without statins, showed a mean decrease in: PD (0.4 mm versus 0.13 mm); percentage of PS sites > 5 mm (4.16 percent versus 1.09 percent); clinical attachment level (0.5 mm versus 0.2 mm), bleeding index (27.16 percent versus 8.8 percent), and periodontal inflamed surface area (305.68 versus 121.35 mm2). Conclusions These results suggest that patients with chronic periodontitis may benefit from systemic therapy with statins. Randomized clinical trials with optimal sample size are required to check the effect and impact of statins on the periodontal status.

ABSTRACT

PURPOSE: To evaluate the heart and the Tc-99m-sestamibi biodistribution after statin pretreatment in a rat model of abdominal sepsis. METHODS: Twenty-four Wistar rats were randomly distributed into four groups (n=6 per group): 1) sepsis with simvastatin treatment, 2) sepsis with vehicle, 3) sham control with simvastatin and 4) sham control with vehicle. 24 hours after cecal ligation and puncture rats received 1.0MBq of Tc-99m-sestamibi i.v. 30min after, animals were euthanized for ex-vivo tissue counting and myocardium histological analysis. RESULTS: Myocardial histologic alterations were not detected 24 hours post-sepsis. There was significantly increased cardiac Tc-99m-sestamibi activity in the sepsis group with simvastatin treatment (1.9±0.3%ID/g, p<0.001) in comparison to the sepsis group+vehicle (1.0±0.2%ID/g), control sham group+ simvastatin (1.2±0.3%ID/g) and control sham group (1.3±0.2%ID/g). Significant Tc-99m-sestamibi activity in liver, kidney and lungs was also detected in the sepsis group treated with simvastatinin comparison to the other groups. CONCLUSIONS: Statin treatment altered the biodistribution of Tc-99m-sestamibi with increased cardiac and solid organ activity in rats with abdominal sepsis, while no impact on controls. Increased myocardial tracer activity may be a result of a possible protection effect due to increased tissue perfusion mediated by statins. .

ABSTRACT

PURPOSE: To evaluate the effect of simvastatin on relapse of tooth movement in rats using microtomography (micro CT), as well as the correlation of bone density with the orthodontic relapse. METHODS: Twenty-five adult male Wistar rats, divided into two groups, had stainless steel springs installed on left maxillary first molar. The molars were moved for 18 days, and after removing the springs, were applied by oral gavage, 5mg/kg of simvastatin in the experimental group for 20 days. Tooth relapse was assessed with a micro CT scanner, and the images chosen through the Data Viewer software 1.5.0.0 had their measurement guides made and checked by the software Image ProR plus 5.1, and compared by Mann-Whitney test. After rats were sacrificed, bone mineral density was evaluated by micro CT through the software CT Analyzer 1.13 and compared by independent T-test, as well as by Spearman correlation test. RESULTS: Relapse and bone mineral density (BMD) was lower in the experimental group than in the control group, however without a statistically significant difference. CONCLUSION: Simvastatin did not inhibit the relapse of tooth movement in rats, and there was no correlation between bone density and orthodontic relapse. .

Statin treatment in association with physical exercise practice can substantially reduce cardiovascular mortality risk of dyslipidemic individuals, but this practice is associated with myopathic event exacerbation. This study aimed to present the most recent results of specific literature about the effects of statins and its association with physical exercise on skeletal musculature. Thus, a literature review was performed using PubMed and SciELO databases, through the combination of the keywords “statin” AND “exercise” AND “muscle”, restricting the selection to original studies published between January 1990 and November 2013. Sixteen studies evaluating the effects of statins in association with acute or chronic exercises on skeletal muscle were analyzed. Study results indicate that athletes using statins can experience deleterious effects on skeletal muscle, as the exacerbation of skeletal muscle injuries are more frequent with intense training or acute eccentric and strenuous exercises. Moderate physical training, in turn, when associated to statins does not increase creatine kinase levels or pain reports, but improves muscle and metabolic functions as a consequence of training. Therefore, it is suggested that dyslipidemic patients undergoing statin treatment should be exposed to moderate aerobic training in combination to resistance exercises three times a week, and the provision of physical training prior to drug administration is desirable, whenever possible.


A associação do tratamento medicamentoso por estatinas com a prática de exercícios físicos pode reduzir substancialmente o risco de mortalidade cardiovascular de indivíduos dislipidêmicos, porém sua realização vem sendo associada à exacerbação de quadros miopáticos. O presente trabalho teve como objetivo apresentar os resultados mais recentes da literatura específica sobre os efeitos da associação de estatinas ao exercício físico na musculatura esquelética. Para tanto, realizou-se levantamento da literatura nas bases de dados PubMed e SciELO, utilizando a combinação dos unitermos: “estatina/estatinas” AND “exercício” AND “músculo” (“statin” AND “exercise” AND “muscle”), sendo selecionados apenas artigos originais publicados entre janeiro de 1990 e novembro de 2013. Foram analisados 16 artigos que avaliaram o efeito da associação das estatinas com exercício agudo ou crônico na musculatura esquelética. Os resultados dos estudos apontaram que atletas podem experimentar efeitos deletérios na musculatura esquelética quando do uso de estatinas, visto que os quadros de exacerbação da lesão muscular pelo exercício foram mais frequentes com treinamento intenso ou exercícios agudos excêntricos e extenuantes. O treinamento físico moderado, por sua vez, quando associado às estatinas, não aumenta os relatos de dor nem os níveis de creatina quinase, além de acarretar ganhos nas funções musculares e metabólicas advindas do treinamento. Sugere-se, portanto, que pacientes dislipidêmicos em tratamento com estatinas sejam expostos ao treinamento físico aeróbio combinado a exercícios resistidos, de intensidade moderada, em três sessões semanais, sendo que a oferta do treinamento físico previamente à administração do tratamento medicamentoso, quando possível, faz-se desejável.

ABSTRACT

A sixty-one year old white female was referred to the Dermatology Department to treat an ingrown nail in the inner corner of the left hallux. Examination of the entire nail unit showed the presence of xanthonychia in the outer corner besides thickening and increase in the transverse curvature of the nail plate. Dermoscopy and nuclear magnetic resonance of the free edge of the nail plate detected characteristic signs of onychomatricoma, a diagnosis that was later confirmed by anatomopathological exam.

ABSTRACT

OBJECTIVES: Prevention of the development of paraplegia during the repair of the damage caused by descending thoracic and thoracoabdominal aneurysms remains an important issue. Therefore, we investigated the protective effect of atorvastatin on ischemia-induced spinal cord injury in a rabbit model. METHOD: Thirty-two rabbits were divided into the following four equally sized groups: group I (control), group II (ischemia-reperfusion), group III (atorvastatin treatment) and group IV (atorvastatin withdrawal). Spinal cord ischemia was induced by clamping the aorta both below the left renal artery and above the iliac bifurcation. Seventy-two hours postoperatively, the motor function of the lower limbs of each animal was evaluated according to the Tarlov score. Spinal cord and blood samples were obtained for histopathological and biochemical analyses. RESULTS: All of the rabbits in group II exhibited severe neurological deficits. Atorvastatin treatment (groups III and IV) significantly reduced the level of motor dysfunction. No significant differences were observed between the motor function scores of groups III and IV at the evaluated time points. Light microscopic examination of spinal cord tissue samples obtained at the 72nd hour of reperfusion indicated greater tissue preservation in groups III and IV than in group II. CONCLUSION: This study demonstrates the considerable neuroprotective effect of atorvastatin on the neurological, biochemical and histopathological status of rabbits with ischemia-induced spinal cord injury. Moreover, the acute withdrawal of atorvastatin therapy following the induction of spinal cord ischemia did not increase the neuronal damage in this rabbit model. .
