Should all patients with psoriasis receive statins? Analysis according to different strategies

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.

Elegibilidad para la indicación de inhibidores de PCSK9 según las recomendaciones de diferentes sociedades científicas / Eligibility for the indication of PCSK9 inhibitors according to the recommendations of different scientific societies

La reducción del colesterol-LDL (C-LDL) es un objetivo primordial en prevención cardiovascular. Estudios recientes demostraron beneficio clínico al administrar inhibidores de la proprotein convertase subtilisin/kexin-9 (iPCSK9) a pacientes que no habían logrado la meta de C-LDL con estatinas de alta intensidad y ezetimibe, sin embargo el uso de estos fármacos está limitado por su costo. El American College of Cardiology, la Sociedad Argentina de Cardiología y la European Society of Cardiology recomiendan una meta de C-LDL menor a 70 mg/dl en prevención secundaria, determinando umbrales de C-LDL de 70, 100 o 140 mg/dl respectivamente, para iniciar el tratamiento con iPCSK9. Con el objetivo de evaluar el esquema hipolipemiante prescripto en internados por síndrome coronario agudo o revascularización coronaria y analizar la proporción de elegibles para ser tratados con iPCSK9 en un escenario real y simulado, realizamos un estudio que incluyó 351 pacientes con enfermedad coronaria, tomados de una base de datos electrónica de un hospital universitario. El 48.4% recibió estatinas de elevada intensidad, 11.4% ezetimibe y 54.7% no logró la meta de C-LDL menor a 70 mg/dl. Utilizando un modelo de simulación en el que todos serían medicados con estatinas de elevada intensidad y ezetimibe, la elegibilidad para prescribir iPCSK9 fue de 31.1%, 12.8% y 9.1% según los umbrales de C-LDL determinados por las tres sociedades científicas. Nuestro estudio demostró una brecha entre las recomendaciones de los consensos para reducir el colesterol y la práctica habitual que debería ser minimizada para optimizar la relación costo/efectividad en prevención secundaria.

LDL-cholesterol (LDL-C) lowering is a primary objective in cardiovascular prevention. Recent studies demonstrated clinical benefit when proprotein convertase subtilisin/kexin-9 inhibitors (PCSK9i) were added to the treatment in patients who had not achieved the LDL-C goal despite being treated with high intensity statins and ezetimibe, however the use of these drugs is limited by their cost. The American College of Cardiology, the Argentine Society of Cardiology and the European Society of Cardiology recommend an LDL-C goal less than 70 mg/dl in secondary prevention, determining thresholds of LDL-C to start treatment with PCSK9i of 70, 100 or 140 mg/dl respectively. In order to evaluate the lipid-lowering regimen prescribed in patients hospitalized for acute coronary syndrome or coronary revascularization and analyze the proportion of eligible to be treated with PCSK9i in a real and simulated scenario, we conducted a study that included 351 patients with coronary disease collected from an electronic database of a university hospital. The 48.4% received high intensity statins, 11.4% ezetimibe and 54.7% did not achieve the LDL-C goal of less than 70 mg/dL. Using a simulation model in which all would be treated with high intensity statins and ezetimibe, the eligibility to prescribe PCSK9i was 31.1%, 12.8% and 9.1% according to the C- LDL thresholds determined by the three scientific societies. Our study demonstrated a gap between the consensus recommendations for LDL-C lowering and the current practice that should be minimized to optimize the cost/effectiveness ratio in secondary prevention.

Changes in Medical Management after Coronary CT Angiography / Mudanças no Manejo Clínico após Angiotomografia Coronariana

AbstractIntroduction:Coronary computed tomography angiography (CCTA) allows for non-invasive coronary artery disease (CAD) phenotyping. There are still some uncertainties regarding the impact this knowledge has on the clinical care of patients.Objective:To determine whether CAD phenotyping by CCTA influences clinical decision making by the prescription of cardiovascular drugs and their impact on non-LDL cholesterol (NLDLC) levels.Methods:We analysed consecutive patients from 2008 to 2011 submitted to CCTA without previous diagnosis of CAD that had two serial measures of NLDLC, one up to 3 months before CCTA and the second from 3 to 6 months after.Results:A total of 97 patients were included, of which 69% were men, mean age 64 ± 12 years. CCTA revealed that 18 (18%) patients had no CAD, 38 (39%) had non-obstructive (< 50%) lesions and 41 (42%) had at least one obstructive ≥ 50% lesion. NLDLC was similar at baseline between the grups (138 ± 52 mg/dL vs. 135 ± 42 mg/dL vs. 131 ± 44 mg/dL, respectively, p = 0.32). We found significative reduction in NLDLC among patients with obstrctive lesions (-18%, p = 0.001). We also found a positive relationship between clinical treatment intensification with aspirin and cholesterol reducing drugs and the severity of CAD.Conclusion:Our data suggest that CCTA results were used for cardiovascular clinical treatment titration, with especial intensification seen in patients with obstructive ≥50% CAD.

ResumoFundamento:A Angiotomografia Coronariana (AngioTC Cor) permite a fenotipagem de Doença Arterial Coronariana (DAC) de forma não invasiva. Ainda há incertezas sobre o impacto que esse conhecimento promove no tratamento clínico do paciente.Objetivo:Avaliar se a fenotipagem da DAC por AngioTC Cor influencia na tomada de decisão sobre o início da terapêutica cardiovascular e seu impacto nos níveis séricos de colesterol não HDL (CNHDL).Métodos:Foram analisados pacientes consecutivos sem diagnóstico prévio de DAC que realizaram AngioTC Cor entre os anos 2008 e 2011 e que possuíam duas dosagens seriadas de colesterol até três meses antes da AngioTC Cor, e de três a seis meses após.Resultados:Um total de 97 pacientes foram incluídos, sendo 69% homens, idade média de 64 ± 12 anos. A AngioTC Cor revelou que 18 (18%) pacientes não tinham lesões detectáveis, 38 (39%) tinham lesões não obstrutivas < 50%, e 41 (42%) tinham ao menos uma lesão obstrutiva ≥ 50%. As medidas de CNHDL basal foram similares entre os grupos, (138 ± 52 mg/dL vs. 135 ± 42 mg/dL vs. 131 ± 44 mg/dL, respectivamente, p = 0,32). Observou-se redução significativa do CNHDL apenas no grupo com lesões obstrutivas ≥ 50% (-18%, p = 0,001). Observa-se ainda relação entre a intensificação do tratamento clínico com AAS e drogas redutoras de colesterol proporcional à gravidade da DAC pela AngioTC Cor.Conclusão:Esses dados sugerem que o resultado da AngioTC Cor foi utilizado para a titulação terapêutica de pacientes com DAC, sendo o tratamento intensificado especialmente em DAC obstrutiva ≥ 50%.

Preoperative predictive factors for intensive care unit admission after pulmonary resection / Fatores preditivos pré-operatórios de internação em unidade de terapia intensiva após ressecção pulmonar

Objective: To determine whether the use of a set of preoperative variables can predict the need for postoperative ICU admission. Methods: This was a prospective observational cohort study of 120 patients undergoing elective pulmonary resection between July of 2009 and April of 2012. Prediction of ICU admission was based on the presence of one or more of the following preoperative characteristics: predicted pneumonectomy; severe/very severe COPD; severe restrictive lung disease; FEV1 or DLCO predicted to be < 40% postoperatively; SpO2 on room air at rest < 90%; need for cardiac monitoring as a precautionary measure; or American Society of Anesthesiologists physical status ≥ 3. The gold standard for mandatory admission to the ICU was based on the presence of one or more of the following postoperative characteristics: maintenance of mechanical ventilation or reintubation; acute respiratory failure or need for noninvasive ventilation; hemodynamic instability or shock; intraoperative or immediate postoperative complications (clinical or surgical); or a recommendation by the anesthesiologist or surgeon to continue treatment in the ICU. Results: Among the 120 patients evaluated, 24 (20.0%) were predicted to require ICU admission, and ICU admission was considered mandatory in 16 (66.6%) of those 24. In contrast, among the 96 patients for whom ICU admission was not predicted, it was required in 14 (14.5%). The use of the criteria for predicting ICU admission showed good accuracy (81.6%), sensitivity of 53.3%, specificity of 91%, positive predictive value of 66.6%, and negative predictive value of 85.4%. Conclusions: The use of preoperative criteria for predicting the need for ICU admission after elective pulmonary resection is feasible and can reduce the number of patients staying in the ICU only for monitoring. .

Objetivo: Avaliar se a utilização de um conjunto de variáveis pré-operatórias é capaz de antever a necessidade de internação em UTI no pós-operatório. Métodos: Estudo de coorte observacional prospectivo, com 120 pacientes submetidos à ressecção pulmonar eletiva entre julho de 2009 e abril de 2012. A previsão de indicação de internação em UTI indicação foi baseada na presença de uma ou mais das seguintes condições pré-operatórias: previsão de pneumonectomia; DPOC grave/muito grave; doença restritiva grave; VEF1 ou DLCO previstos para o pós-operatório < 40% do previsto; SpO2 em repouso e ar ambiente < 90%; necessidade de monitorização cardíaca profilática; classificação da American Society of Anesthesiologists ≥ 3. O padrão ouro para internação justificada em UTI foi baseado na presença de uma ou mais das seguintes condições pós-operatórias: manutenção de ventilação mecânica ou reintubação; insuficiência respiratória aguda ou necessidade de ventilação não invasiva; instabilidade hemodinâmica ou choque; intercorrências intraoperatórias ou no pós-operatório imediato (cirúrgicas ou clínicas); indicação do anestesiologista ou cirurgião para a manutenção de tratamento na UTI. Resultados: Dos 120 pacientes avaliados, houve previsão de necessidade de internação em UTI em 24 (20,0%), sendo essa considerada justificada em 16 deles (66,6%) desses 24, ao passo que dos 96 pacientes sem previsão de necessidade de internação em UTI, essa foi necessária em 14 (14,5%). A utilização dos critérios preditivos para a internação em UTI mostrou boa acurácia (81,6%), sensibilidade de 53,3%, especificidade de 91%, valor preditivo positivo de 66,6% e valor preditivo negativo de 85,4%. Conclusões: A utilização de critérios pré-operatórios para a indicação de internação em UTI após ressecção pulmonar eletiva é factível e é capaz de reduzir o número de pacientes que aí permanecem apenas para vigilância. .

Influence of PPARA, RXRA, NR1I2 and NR1I3 gene polymorphisms on the lipid-lowering efficacy and safety of statin therapy / Influência de polimorfismos nos genes PPARA, RXRA, NR1I2 e NR1I3 na eficácia hipolipemiante e na segurança da terapia com estatinas

OBJECTIVE: The aim of the present study was investigate the association between six genetic variants in the nuclear receptor genes PPARA, RXRA, NR1I2 and NR1I3 and the lipid-lowering efficacy and safety of statin therapy. SUBJECTS AND METHODS: The study was carried out on 240 Brazilian hypercholesterolemic patients on simvastatin and atorvastatin therapy. The polymorphisms were analyzed by PCR-based methods. RESULTS: The NR1I3 rs2307424 genotype distribution was different between subjects with and without adverse drug reactions. Among subjects in the ADR group, no T/T homozygotes were observed for this polymorphism, while in the non-ADR group the frequency of this genotype was 19.4% (P = 0.007, after multiple testing corrections P = 0.042). CONCLUSION: The polymorphisms investigated in PPARA (rs1800206), RXRA (rs11381416), and NR1I2 (rs1523130) did not influence the lipid-lowering efficacy and safety of statin. Our results show the possible influence of NR1I3 genetic variant on the safety of statin.

Control of blood lipids in the elderly

In individuals 65 years of age and older cardiovascular disease is the leading cause of death around the world. Hypercholesterolemia is among the major risk factors for the development of cardiovascular disorders. Most of the scientifically based studies on preventive measures for cardiovascular conditions have been conducted in subjects younger then 65 years of age. In the last 10 years some clinical trials have included a considerable number of individuals older than 65 years of age providing a scientific basis for therapeutic and preventive intervention in the aged. In this article we summarize the main studies concerning lipids as risk factors for cardiovascular disease in the elderly and we present the indicated primary and secondary preventive measures for reducing cholesterol levels in the elderly leading to a reduction in total and cardiac mortality, and to lesser development of myocardial infarction and coronary artery disease

Primary and secondary prevention of cardiovascular disease in the elderly

Cardiovascular disease is the commonest cause of death and hospitalization in patients 65 years of age or older. The main offenders among the cardiovascular disorders in this age are CHD and hypertension. Many non-pharmacologic and pharmacologic measures in the middle-aged persons have confirmed for many years the effectiveness of primary and secondary prevention. Multiple intervention trials in the recent years have also demonstrated the effectiveness of these measures in patients 65 years of age and older. A summary of the main primary and secondary non-pharmacologic and pharmacologic measures that have been proven to be effective and useful in elderly patients has been presented with particular attention to hypertension and CHD. It also has been demonstrated that elderly patients have the capacity to follow the instructions of their physicians and that, as younger patients, they respond to these measures

Farmacoterapia de la dislipidemia en el anciano / Drug therapy of dislipidaemia in the elderly

El paciente anciano posee características peculiares que determinan que los medicamentos tengan una farmacodinamia diferente a la de los adultos de menor edad. Esto también tiene plena validez para los medicamentos hipolipemiantes. La conveniencia de indicar tratamientos hipolipemiantes en el adulto mayor ha suscitado interesantes polémicas; sin embargo, parece haber consenso en el sentido de que los ancianos con buena perspectiva de vida debe tratarse la dislipidemia. Los medicamentos deben seleccionarse de acuerdo con las características individuales del paciente de avanzada edad. El policosanol es uno de los medicamentos que por su eficacia y tolerabilidad se ajusta mejor a las condiciones del anciano dislipidémico
