ABSTRACT

Resumo Fundamento: As diretrizes da Sociedade Europeia de Cardiologia recomendam um nível de colesterol LDL (LDL-C) < 55 mg/dL para pacientes com doença cardiovascular estabelecida. Embora a fórmula de Friedewald ainda seja amplamente utilizada para estimar o LDL-C, a fórmula mais recente de Martin-Hopkins mostrou maior precisão. Objetivos: Nosso objetivo foi avaliar: A) a proporção de pacientes que atingiram a meta de LDL-C e as terapias utilizadas em um centro terciário; B) o impacto da utilização do método de Martin-Hopkins em vez do método de Friedewald na proporção de pacientes controlados. Métodos: Estudo transversal monocêntrico, incluindo pacientes consecutivos pós-infarto do miocárdio, acompanhados por 20 cardiologistas, em um hospital terciário. Os dados foram coletados retrospectivamente de consultas clínicas realizadas após abril de 2022. Para cada paciente, os níveis de LDL-C e o atingimento das metas foram estimados a partir de um perfil lipídico ambulatorial, utilizando as fórmulas de Friedewald e Martin-Hopkins. Um valor-p bicaudal < 0,05 foi considerado estatisticamente significativo para todos os testes. Resultados: Foram incluídos 400 pacientes (com 67 ± 13 anos, 77% do sexo masculino). Utilizando a fórmula de Friedewald, a mediana de LDL-C sob terapia foi de 64 (50-81) mg/dL, e 31% tinham LDL-C dentro da meta. Estatinas de alta intensidade foram usadas em 64% dos pacientes, 37% estavam em uso de ezetimiba e 0,5% estavam em uso de inibidores de PCSK9. A terapia combinada de estatina de alta intensidade + ezetimiba foi utilizada em 102 pacientes (26%). A aplicação do método de Martin-Hopkins reclassificaria um total de 31 pacientes (7,8%). Entre aqueles considerados controlados pela fórmula de Friedewald, 27 (21,6%) teriam LDL-C estimado por Martin-Hopkins acima da meta. Conclusões: Menos de um terço dos pacientes pós-infarto do miocárdio apresentaram LDL-C dentro da meta. A aplicação da fórmula de Martin-Hopkins reclassificaria um quinto dos pacientes presumivelmente controlados no grupo de pacientes não controlados.


Abstract Background: The European Society of Cardiology guidelines recommend an LDL-cholesterol (LDL-C) < 55 mg/dL for patients with established cardiovascular disease. While the Friedewald equation to estimate LDL-C is still widely used, the newer Martin-Hopkins equation has shown greater accuracy. Objectives: We aimed to assess: A) the proportion of patients reaching LDL-C goal and the therapies used in a tertiary center; B) the impact of using the Martin-Hopkins method instead of Friedewald's on the proportion of controlled patients. Methods: A single-center cross-sectional study including consecutive post-myocardial infarction patients followed by 20 cardiologists in a tertiary hospital. Data was collected retrospectively from clinical appointments that took place after April 2022. For each patient, the LDL-C levels and attainment of goals were estimated from an ambulatory lipid profile using both Friedewald and Martin-Hopkins equations. A two-tailed p-value of < 0.05 was considered statistically significant for all tests. Results: Overall, 400 patients were included (aged 67 ± 13 years, 77% male). Using Friedewald's equation, the median LDL-C under therapy was 64 (50-81) mg/dL, and 31% had LDL-C within goals. High-intensity statins were used in 64% of patients, 37% were on ezetimibe, and 0.5% were under PCSK9 inhibitors. Combination therapy of high-intensity statin + ezetimibe was used in 102 patients (26%). Applying the Martin-Hopkins method would reclassify a total of 31 patients (7.8%). Among those deemed controlled by Friedewald's equation, 27 (21.6%) would have a Martin-Hopkins' LDL-C above goals. Conclusions: Less than one-third of post-myocardial infarction patients had LDL-C within the goal. Applying the Martin-Hopkins equation would reclassify one-fifth of presumably controlled patients into the non-controlled group.

ABSTRACT

Abstract Diabetes mellitus (DM), an endocrine syndrome characterized by high blood glucose levels due to abrogated insulin activity. The existing treatments for DM have side effects and varying degrees of efficacy. Therefore, it is paramount that novel approaches be developed to enhance the management of DM. Therapeutic plants have been accredited as having comparatively high efficacy with fewer adverse effects. The current study aims to elucidate the phytochemical profile, anti-hyperlipidemic, and anti-diabetic effects of methanolic extract D. salicifolia (leaves) in Alloxan-induced diabetic mice. Alloxan was injected intraperitoneally (150 mg kg-1, b.w), to induced diabetes in mice. The mice were divided into three groups (n=10). Group 1 (normal control) received normal food and purified water, Group II (diabetic control) received regular feed and clean water and group III (diabetic treated) received a methanolic extract of the plant (300 mg kg-1) for 28 days with a typical diet and clean water throughout the experiment. Blood samples were collected to checked serum glucose and concentration of LDL, TC, TG. The extract demonstrated significant antihyperglycemic activity (P 0.05), whereas improvements in mice's body weight and lipid profiles were observed after treatment with the extract. This study establishes that the extract has high efficacy with comparatively less toxicity that can be used for DM management.


Resumo Diabetes mellitus (DM) é uma síndrome endócrina caracterizada por níveis elevados de glicose no sangue devido à atividade anulada da insulina. Os tratamentos existentes para o DM têm efeitos colaterais e vários graus de eficácia. Portanto, é fundamental que novas abordagens sejam desenvolvidas para aprimorar o manejo do DM. As plantas terapêuticas foram acreditadas como tendo eficácia comparativamente alta com menos efeitos adversos. O presente estudo visa elucidar o perfil fitoquímico, efeitos anti-hiperlipidêmicos e antidiabéticos do extrato metanólico de D. salicifolia (folhas) em camundongos diabéticos induzidos por aloxana. Alloxan foi injetado por via intraperitoneal (150 mg kg-1, b.w), para induzir diabetes em camundongos. Os camundongos foram divididos em três grupos (n = 10). Grupo 1 (controle normal) recebeu ração normal e água purificada, Grupo II (controle diabético) recebeu ração regular e água limpa, e o grupo III (tratamento diabético) recebeu extrato metanólico da planta (300 mg kg-1) por 28 dias com uma dieta típica e água limpa durante todo o experimento. Amostras de sangue foram coletadas para verificar a glicose sérica e a concentração de LDL, TC, TG. O extrato demonstrou atividade anti-hiperglicêmica significativa (P 0,05), enquanto melhorias no peso corporal e no perfil lipídico dos camundongos foram observadas após o tratamento com o extrato. Este estudo estabelece que o extrato tem alta eficácia com comparativamente menos toxicidade e pode ser usado para o controle do DM.

ABSTRACT

RESUMEN Introducción: el modelo SMART-REACH predice el riesgo de eventos cardiovasculares recurrentes. Objetivos: los objetivos de este estudio fueron: a) evaluar el riesgo residual en una población en prevención secundaria y niveles de colesterol asociado a lipoproteínas de baja densidad (C-LDL) fuera de meta; b) mediante un modelo de simulación, determinar el impacto de optimizar las terapias hipolipemiantes en términos de reducción del riesgo residual. Material y métodos: estudio transversal, descriptivo y multicéntrico. Se incluyeron consecutivamente pacientes con antecedentes cardiovasculares y un C-LDL mayor o igual que 55 mg/dL. El riesgo de eventos recurrentes (infarto agudo de miocardio, accidente cerebrovascular o muerte vascular) a 10 años y a lo largo de la vida se estimó utilizando el modelo SMART-REACH. Mediante una simulación, se optimizó el tratamiento hipolipemiante de cada paciente (utilizando estatinas, ezetimibe o inhibidores de proproteína convertasa subtilisina kexina tipo 9 [iPCSK9]), se estimó el descenso del C-LDL, se verificó el alcance del objetivo lipídico y se calculó la reducción del riesgo cardiovascular y el número necesario a tratar (NNT) correspondiente. Resultados: se incluyeron 187 pacientes (edad media 67,9 ± 9,3 años, 72,7% hombres). Los riesgos residuales calculados a 10 años y a lo largo de la vida fueron 37,1 ± 14,7% y 60,3 ± 10,7%, respectivamente. Globalmente, se pudo optimizar una sola estrategia farmacológica con estatinas, ezetimibe o un iPCSK9 en el 38,5%, el 11,5% y el 5,5% de la población, respectivamente. La optimización basada en dos tratamientos se realizó en el 27,5% (estatinas + ezetimibe), el 7,7% (estatinas + iPCSK9) y el 1,1% (ezetimibe + iPCSK9) de los casos. En 15 pacientes se optimizó el tratamiento considerando los tres fármacos. El 53,9% y el 62,9% de las acciones para optimizar el tratamiento mostraron un NNT menor que 30 para evitar un evento a 10 años o a lo largo de la vida, respectivamente. Conclusión: en este estudio, los pacientes con antecedentes cardiovasculares que no alcanzan la meta de C-LDL mostraron un riesgo residual considerable. La simulación mostró un importante margen para optimizar el tratamiento, con un impacto notable en el riesgo residual.


ABSTRACT Background: The SMART-REACH model predicts the risk or recurrent cardiovascular events. Objectives: The objectives of this study were: a) to evaluate the residual cardiovascular risk in a secondary prevention population with LDL-C levels above the recommended goal, using a simulation model; and b) to determine the impact of optimizing lipid-lowering therapies in terms of residual cardiovascular risk reduction. Methods: We conducted a cross-sectional, descriptive and multicenter study. Patient with a history of cardiovascular disease and a LDL-C ≥55 mg/dL were consecutively included. The 10-year and lifetime risk of recurrent events (myocardial infarction, stroke, or vascular death) were estimated using the SMART-REACH model. By means of a simulation, lipid-lowering treatment was optimized for each patient [using statins, ezetimibe and/or PCSK9 (PCSK9) inhibitors], with estimation of LDL-C reduction, checking if lipid-lowering goal was achieved and calculating the reduction in cardiovascular risk and the corresponding number needed to treat (NNT). Results: The cohort was made up of 187 patients; mean age was 67.9 ± 9.3 years and 72.7% were men. The calculated 10-year and lifetime residual risks were 37.1 ± 14.7% and 60.3 ± 10.7%, respectively. Overall, treatment was optimized with a single pharmacological strategy with statins, ezetimibe or PCSK9 inhibitor in 38.5%, 11.5% and 5.5% of the population, respectively. Optimization based on two treatments was performed in 27.5% (statins + ezetimibe), 7.7% (statins + PCSK9 inhibitor) and 1.1% (ezetimibe + PCSK9 inhibitor) of the cases. In 15 patients, treatment was optimized when the three drugs (statins + ezetimibe + PCSK9 inhibitor) were considered. Overall, 53.9% and 62.9% of the actions implemented to optimize treatment showed a 10-year or lifetime NNT < 30 to prevent an event, respectively. Conclusion: In this study, patients with a history of cardiovascular disease who do not reach LDL-C goal showed significant residual cardiovascular risk. The simulation model showed a significant margin for optimizing treatment, with a marked reduction in residual cardiovascular risk.

ABSTRACT

ABSTRACT Background: Approximately 71 million people are chronically infected with hepatitis C virus (HCV) worldwide. A significant number of these individuals will develop liver cirrhosis and/or hepatocellular carcinoma. Beyond the liver, there is a sizeable body of scientific evidence linking cardiovascular disease and chronic hepatitis C (CHC); however, the biological mechanisms behind the concurrence of these conditions have not been completely clarified yet. Objective: To evaluate associations between hepatic histology, clinical comorbidities and lipid profile in patients with CHC. To investigate associations between liver histology and demographic, nutritional, biochemical and virological parameters. Methods: Eight-five patients with CHC prospectively underwent hepatic biopsy. Liver fragments were obtained from each patient by percutaneous route using a Menghini needle. Fibrosis was evaluated according to the METAVIR scoring system, as follows: F0, no fibrosis; F1, fibrous portal expansion; F2, fibrous portal widening with few septa; F3, bridging fibrosis with architectural distortion; and F4, liver cirrhosis. The activity was classified based on the degree of lymphocyte infiltration and hepatocyte necrosis, from A0 to A3. The diagnosis of liver disease was based on clinical, biochemical, histological, and radiological methods. The data were analyzed by logistic regression models. Results: This cross-sectional study included 85 outpatients followed at the tertiary care ambulatory centre with a mean age of 57.2±10.7 years and 45 (52.9%) were females. There were 10 patients with cirrhosis. Patients with a METAVIR F3-F4 were significantly older (P=0.02) and had higher levels of ALT (P=0.0006), AST (P<0.0001), γ-GT (P=0.03) and bilirubin (P=0.001) and higher prothrombin time than patients with F0-F2 score. Albumin levels (P=0.01) were significantly lower in METAVIR F3-F4. Age (OR=1.09; 95%CI=1.02-1.16; P=0.02), steatosis (OR=4.03; 95%CI=1.05-15.45; P=0.04) and high-density lipoprotein cholesterol (HDL-C) <60 mg/dL (OR=7.67; 95%CI=1.71-34.49; P=0.008) were independently associated with fibrosis. Hypertension (OR=6.36; 95%CI=1.31-30.85; P=0.02) and HDL-C <60 mg/dL (OR=9.85; 95%CI=2.35-41.39; P=0.002) were independently associated with necroinflammatory activity. Hypertension (OR=6.94; 95%CI=1.92-25.05; P=0.003) and HDL-C <60 mg/dL (OR=3.94; 95%CI=1.27-12.3; P=0.02) were associated with interface inflammatory activity. Triglycerides (TG ≥150 mg/dL) remained associated with lobular inflammatory activity. Conclusion: cholesterol levels <60 mg/dL were independently associated with necroinflammatory activity in chronic hepatitis C. Patients with hypertension are at an increased risk of developing necroinflammatory activity.


RESUMO Contexto: Aproximadamente 71 milhões de pessoas estão infectadas pelo vírus da hepatite C em todo o mundo. Um número significativo desses indivíduos desenvolverá cirrose hepática e/ou carcinoma hepatocelular. Além do fígado, há evidências científicas que associam doenças cardiovasculares e hepatite C crônica; no entanto, os mecanismos biológicos implicados na ocorrência dessas condições ainda não foram completamente esclarecidos. Objetivo: Avaliar a associação entre histologia hepática, comorbidades clínicas e perfil lipídico em pacientes com hepatite C crônica. Investigar associações entre histologia hepática e parâmetros demográficos, nutricionais, bioquímicos e virológicos. Métodos: Oitenta e cinco pacientes com hepatite C crônica foram prospectivamente submetidos à biópsia hepática. Biópsias hepáticas foram obtidas de cada paciente por via percutânea com agulha de Menghini. A fibrose foi avaliada de acordo com o sistema de pontuação METAVIR, como segue: F0, sem fibrose; F1, expansão portal fibrosa; F2, alargamento portal fibroso com poucos septos; F3, fibrose em ponte com distorção arquitetônica; e F4, cirrose hepática. A atividade foi classificada com base no grau de infiltração de linfócitos e necrose de hepatócitos, de A0 a A3. O diagnóstico da doença hepática foi baseado em métodos clínicos, bioquímicos, histológicos e radiológicos. Os dados foram analisados por modelos de regressão logística. Resultados: Neste estudo transversal, realizado em um ambulatório do hospital universitário, foram incluídos 85 pacientes que tinham média de idade de 57,2±10,7 anos, sendo 45 (52,9%) do sexo feminino. Havia 10 pacientes com cirrose. Os pacientes com METAVIR F3-F4 eram significativamente mais velhos (P=0,02) e tinham níveis mais elevados de ALT (P=0,0006), AST (P<0,0001), γ-GT (P=0,03) e bilirrubina (P=0,001) e, maior tempo de protrombina do que pacientes com escore F0-F2. Os níveis de albumina (P=0,01) foram significativamente mais baixos naqueles classificados como METAVIR F3-F4. Idade (OR=1,09; IC95%=1,02-1,16; P=0,02), esteatose (OR=4,03; IC95%=1,05-15,45; P=0,04) e HDL-C <60 mg/dL (OR=7,67; 95%IC=1,71-34,49; P=0,008) foram independentemente associados à fibrose. Hipertensão (OR=6,36; IC95%=1,31-30,85; P=0,02) e HDL-C <60 mg/dL (OR=9,85; IC95%=2,35-41,39; P=0,002) foram independentemente associados à atividade necroinflamatória. Hipertensão (OR=6,94; IC 95%=1,92-25,05; P=0,003) e HDL-C <60 mg/dL (OR=3,94; IC95%=1,27-12,3; P=0,02) foram associados à atividade inflamatória de interface. Os triglicerídeos (TG >150 mg/dL) permaneceram associados à atividade inflamatória lobular. Conclusão: Níveis de coleterol HDL <60 mg/dL foram independentemente associados à atividade necroinflamatória na hepatite C crônica. Pacientes com hipertensão têm risco aumentado de desenvolver atividade necroinflamatória.

ABSTRACT

ABSTRACT Background: Monocyte to high-density lipoprotein cholesterol ratio (MHR) is a novel inflammatory biomarker which has been associated with cardiovascular diseases. Objective: To study MHR in patients with psoriasis treated with biological agents. Methods: Between April 2019 and August 2022, MHR was retrospectively evaluated in patients with psoriasis before and 3 months after treatment with infliximab, adalimumab, etanercept, ixekizumab, secukinumab, and ustekinumab in a university hospital in Ankara, Turkey. Results: This study included 128 patients, 53 females and 75 males. 39 (30.5%) patients were treated with infliximab, 26 (20.3%) with adalimumab, 8 (6.3%) with etanercept, 18 (14.1%) with ixekizumab, 12 (9.4%) with secukinumab, and 25 (19.5%) with ustekinumab. The median MHR was 0.0127 (0.0086-0.0165) in females and 0.0146 (0.0119-0.0200) in males (p = 0.011). The median MHR decreased after treatment with adalimumab, ixekizumab, secukinumab, and ustekinumab, whereas it increased after treatment with infliximab and etanercept (p = 0.790, p = 0.015, p = 0.754, p = 0.221, p = 0.276, p = 0.889, respectively). Conclusion: MHR significantly decreased in patients with psoriasis after treatment with ixekizumab. Since high MHR levels have been associated with poor clinical outcomes in patients with cardiovascular diseases, ixekizumab might have a positive impact in the treatment of psoriasis patients who had cardiovascular diseases. We suggest that MHR may be useful both in establishing appropriate biological agent treatment and in the follow-up of patients with psoriasis treated with biological agents.

ABSTRACT

Background: Alopecia areata is a chronic inflammatory skin disease. Oxidative stress may contribute to the pathogenesis of this condition. Aim: To evaluate the serum oxidative stress markers and antioxidant capacity in patients with alopecia areata. Methods: This cross-sectional study was performed on 40 patients with alopecia areata and 40 healthy controls. The fasting blood sugar, C-reactive protein, lipid profile, and serum oxidative markers, including advanced glycation end products and advanced oxidation protein products, were measured in this study. Also, antioxidant enzymes, including paraoxonase-1, lecithin-cholesterol acyltransferase and serum ferric-reducing antioxidant power, were determined. Results: The serum levels of advanced glycation end products and advanced oxidation protein products were significantly higher in patients with alopecia areata, compared to the controls (P < 0.001), whereas the levels of ferric-reducing antioxidant power, paraoxonase-1 and lecithin-cholesterol acyltransferase were significantly lower in patients with alopecia areata, compared to the controls (P < 0.001). The mean fasting blood sugar level was significantly higher in patients with alopecia areata, compared to the controls. The ferric reducing antioxidant power level was significantly associated with the percentage of hair loss (P = 0.01, r = 0.4) and the serum C-reactive protein level (P = 0.03, r = –0.3) in patients with alopecia areata. Limitations: Since the current study had a cross-sectional design, no cause-effect relationship was established between alopecia areata and oxidative stress. The sample size of our study was also small. Conclusion: Based on the present results, the oxidant-antioxidant enzymatic system is impaired in alopecia areata due to the increased oxidative products and decreased antioxidant activity

ABSTRACT

Background and Objective: Cardiovascular disease (CVD) is a significant cause of morbidity and mortality worldwide, with high-risk patients requiring effective management to reduce their risk of cardiovascular events. Bempedoic acid is a novel therapeutic agent recently approved as an add-on therapy to statins in patients with uncontrolled LDL-c. Bempedoic acid inhibits cholesterol synthesis in the liver, which ultimately reduces the risk of cardiovascular events. Therefore, the present study aims to assess the efficacy and safety of bempedoic acid in patients with uncontrolled LDL-c (Previously on moderate or high-intensity statins) with a high risk of CVD in real-world settings. Methods: This is a multicenter, retrospective, observational study on the data of high-risk-CVD patients collected from Bempedoic Acid on Efficacy and Safety in patients (BEST) Registry. The clinical data of 140 patients who were already on statin therapy and were receiving Bempedoic acid at a dose of 180 mg, along with measurements of the level of LDL-c, HbA1c, HDL, TG, TC, PPPG, FPG, AST, ALT, serum creatinine was taken into consideration. The primary outcome includes a change in LDL-c level, and secondary outcomes involve a change in the level of HbA1c, HDL, TG, TC, PPPG, FPG, AST, ALT, and serum creatinine at week 12 and 24. Adverse events were reported at both time points. Results: A total of 140 patients were included in the present study with a mean age of 51.8 ± 9.2 years and had primary confirmed diagnosis of dyslipidemia with uncontrolled LDL-c. The mean levels of LDL-c decreased from the mean baseline value of 142.67 ± 46.49 mg/dL, to 106.78 ±33.92 mg/d; a statistically significant reduction by 23.23% (p < 0.01) at week 12. Similarly, at week 24, the mean LDL-c value reduced to 90.39 ± 38.89 mg/dL. A 33.38 % decrease was observed (p < 0.01). Other parameters such as non-HDL, FPG, PPPG, AST and serum creatinine also showed statistically significant reduction at week 12 and week 24. Conclusion: The present study demonstrates that bempedoic acid is an effective add-on medication in lowering LDL-c levels in high-risk CVD patients with uncontrolled LDL-c.

ABSTRACT

Background: Thyroid diseases are among the most common endocrine disorders worldwide. Thyroid hormones play a key role in regulating the synthesis, metabolism, and mobilization of lipids. Levels of circulating lipids may alter in thyroid dysfunction. Aim and Objectives: The aim of the study was to find out the alterations of lipid levels in thyroid dysfunction. Materials and Methods: The study was designed as cross-sectional observational study and analysis of values was done by significant tests difference in means. 20 patients with hypothyroidism, 20 patients with hyperthyroidism, and 20 normal were participated in the study. Levels of total cholesterol, triglycerides, high density lipoprotein cholesterol (HDL-C), very low density lipoprotein cholesterol (VLDL-C), LDL-C, and LDL/HDL ratio were estimated and compared. Results: In patients with hypothyroidism, there was an increase in total cholesterol, LDL-C, and triglyceride levels and decrease in HDL-C levels. In hyperthyroidism, total cholesterol, triglycerides, LDL-C, VLDL-C, and LDL/HDL ratio were found to be significantly decreased. Conclusion: Altered thyroid function can lead to significant changes in the lipid profile. Hypothyroidism is an important risk factor for heart diseases. Hence, routine screening of thyroid hormones may be of considerable help for early intervention and treatment of thyroid dysfunction-related cardiac disease.

ABSTRACT

Background: Dyslipidemia is defined as the high-density lipoprotein and apolipoprotein A (apo A) levels <10th percentile and/or total cholesterol, triglycerides, low-density lipoprotein (LDL), apolipoprotein B, or Lipoprotein (a) levels more than the 90th percentile. Aim and Objectives: This study aimed to compare the efficacy and safety of the fixed-dose combination of Atorvastatin and Ezetimibe with Atorvastatin monotherapy among patients with dyslipidemia. Materials and Methods: The present study was a randomized, double-blinded, prospective, and parallel-group study. Ninety-two outpatients of age in between 18 and 70 years from the Department of General Medicine who attended the hospital for the treatment of dyslipidemia were selected as study participants. Among 92 patients, 12 patients did not meet the study criteria. The remaining 80 patients were divided into two treatment groups at random and under double-blind conditions (39 in Group A and 41 in Group B). Each patient in both groups was followed for a period of 4 weeks after initiation of therapy. Total cholesterol and LDL-cholesterol levels were recorded at day 1, 2 weeks, and 4 weeks of therapy. Results: In this study, by the end of the study period (4 weeks), tablet Atorvastatin + tablet Ezetimibe combination therapy showed statistical significance difference in reducing mean total cholesterol and mean serum LDL levels in dyslipidemia cases than the group receiving Atorvastatin monotherapy. Conclusion: Atorvastatin in combination with Ezetimibe was more efficacious than Atorvastatin monotherapy in reducing total blood cholesterol and serum LDL levels. Atorvastatin plus Ezetimibe is equally safer as Atorvastatin monotherapy and well tolerated with fewer adverse effects.

ABSTRACT

Background: High cholesterol is the sixth-highest risk factor for death in the globe. Herbal medications regularly complement modern medical care, especially by providing safe, well-tolerated therapies for chronic conditions. Aims and Objectives: The present study was undertaken to evaluate and compare the cholesterol-lowering effects of Terminalia arjuna bark and Bacopa monnieri leaves (Brahmi) extract in human blood samples diagnosed with hyperlipidemia. Materials and Methods: Herbal extract of arjuna (T. arjuna) and Ashwagandha (Withania somnifera [WS]) in distilled water (d/w) and cow’s urine (c/u) [A1, A2, D1, and D2] was taken and added to the pooled serum samples collected aseptically and a kinetic study was performed with it. Cholesterol standard was obtained from Erba Chem Transasia kit (Trinder’s method, endpoint) with a standard cutoff value of 200 mg/dL. Results: Baseline reading of total cholesterol in all samples was 189 mg/dL. After 2 h, the total cholesterol reading in A1 was 159 mg/dL, 157, 162, and 160 mg/dL in A2, D1, and D2, respectively. After 4 h, the total cholesterol reading in A1 was 149 mg/dL, 148, 151, and 149 mg/dL in A2, D1, and D2, respectively. After 6 h, the total cholesterol reading in A1 was 109 mg/dL, 104, 112, and 110 mg/dL in A2, D1, and D2, respectively. Conclusion: From the findings of the present study, it was found that aqueous extract of Ashwagandha (WS) and Arjuna (T. arjuna) was effective in reducing total cholesterol levels. It can be considered a potential therapeutic alternative in patients with hyperlipidemia but warrants further clinical studies.

ABSTRACT

Purpose: To determine the association between serum lipid levels and primary open?angle glaucoma (POAG). Methods: In this case?control study, 50 patients with POAG documented by clinical tests using standard ophthalmologic equipment and 50 age?matched controls were investigated. Twelve?hour fasting serum lipid profiles, including total cholesterol, serum triglycerides, low?density lipoproteins (LDLs), and high?density lipoproteins (HDLs), were compared between the cases and controls. Results: The mean age of cases and controls was 62.84 ± 9.68 and 60.12 ± 8.65, respectively (P = 0.65). High total cholesterol levels (>200 mg/dl) were found in 23 cases (46%) and 8 controls (16%); high serum triglyceride levels (>150 mg/dl) were found in 24 cases (48%) and 7 controls (14%); high LDL levels (130 mg/dl) were found in 28 cases (56%) and 9 controls (18%); and low HDL levels (<40 mg/dl) were found in 38 cases (76%) and 30 controls (60%). The mean total cholesterol levels were 205.24 ± 36.90 mg/dl in cases and 177.68 ± 22.56 mg/dl in controls (P < 0.001); the mean serum triglyceride levels were 150.42 ± 49.55 mg/dl and 130.84 ± 23.16 mg/dl, respectively (P = 0.013); and the mean LDL levels were 139.50 ± 31.03 mg/dl and 114.96 ± 17.73 mg/dl, respectively (P < 0.001). The mean cholesterol, triglyceride, and LDL levels were significantly higher in cases than in controls (P < 0.05). Conclusion: The present study shows that higher proportion of POAG patients have dyslipidemia compared to age?matched controls. Though these findings need to be replicated by others. This study opens new vistas for further studies, such as lowering dyslipidemia, lowering the intra?ocular pressure and incidence of POAG, and whether the use of statins to reduce dyslipidemia affects the progression of POAG.

ABSTRACT

Background: Obesity and overweight is a disorder of unusually increased body fat generally resulting from increased energy intake relative to energy expenditure and is a primary sustenance-related disorder globally. The extensive increase in its prevalence in current years and its association with reduced life expectancy has made obesity one of the most vital public health problems. The purpose of the study was to determine the relationship between serum lipid profile and blood pressure with body mass index (BMI). Material & Methods: A cross-sectional study was carried out in the Department of Physiology and Biochemistry, Rangpur Medical College, Rangpur from January 2013 to December 2013. A purposive sampling technique was followed. A total number of 90 people from 18 to 45 years old were included in the study, categorized into three groups, such as Group-A:(Control 30): Healthy subject of normal weight, Group-B:(Experimental 30): Healthy subject of overweight & Group-C(Experimental-30): Healthy subjects of obese. Verbal consent was taken before recruiting the study population. Completed data forms were reviewed, edited, and processed for computer data entry. The data analysis was performed using the “t” test, “r” test & Statistical Package for the Social Sciences (SPSS) Version 25.0. Results: In group A, the mean BMI of patients was 18.5-22.9, in group B mean BMI of patients was 23.0-24.9, and in group C, the mean BMI of people was 25.0 or greater. The mean ± SD serum LDL-C levels were 107.77 ± 26.720 mg/dl in group A and 134.70 ± 41.787 mg/dl in group B. There was a significant difference (p<0.001) between the two groups. The mean ± SD pulse pressure levels were 38 ± 6.644 mmHg in group A and 41.67 ± 11.167 mmHg in group B. There was no significant difference (p>0.05) between the two groups. Serum total cholesterol levels were positively correlated in groups A & B but the relationship of serum total cholesterol levels was statistically significant in groups A and B. Blood pressure levels were positively correlated in groups A &C but the relationship was statistically non-significant. Conclusion: In this current content, it is difficult to define the specific mechanism involved for significantly higher serum total cholesterol, serum triglyceride, and serum LDL-C levels and non-significantly lesser serum HDL-C levels in overweight & obese people and also non-significantly higher blood pressure in overweight people but significantly higher blood pressure in obese subjects.

ABSTRACT

Objective: Reliable and disaggregated population-based data for cholesterol trends are needed to evaluate overall cardiovascular health, assess the effects of nutritional policies and pharmacological interventions, and guide priority setting. This study aimed to examine the trends and differences in serum total cholesterol-to-high density lipoprotein cholesterol (TC/HDL-C) ratio among U.S. residents by race/ethnicity. Study Design and Setting: Blood lipid measurements, taken from 53,964 noninstitutionalized participants, aged 6 to 80, were obtained from the National Health and Nutrition Examination Survey (NHANES) study. We described the distributions of TC/HDL-C ratio across the life span in four distinct cross-sectional surveys during 2005-2008, 2009-2012, 2013-2016, and 2017-2020, and compared the ratio levels by race/ethnicity. Results: Between 2005 and 2020, favorable trends in lipid ratio levels were observed. In youth aged < 20 years, mean TC/HDL-C ratios were 3.17, 3.15, 3.02, and 3.06 in males; and 3.12, 3.13, 3.03, and 3.02 in females from 2005 to 2020. In adults 20 years old and older, mean TC/HDL ratios declined from 4.30 in 2005-2008, to 4.27 in 2009-2012, 4.17 in 2013-2016, to 3.96 in 2017-2020 in males; while mean TC/HDL-C ratios declined from 3.67 in 2005-2008, to 3.66 in 2009-2012, to 3.54 in 2013-2016, to 3.46 in 2017-2020 in females. Overall, non-Hispanic black individuals tended to have lower mean TC/HDL ratio levels than other groups, while Mexican American individuals tended to have higher TC/HDL ratio levels on average. Conclusion: Further research is needed to determine how racial/ethnic differences in cholesterol ratio affect racial/ethnic differences in cardiovascular disease rates.

ABSTRACT

Background: Cardiovascular diseases (CVDs) rise first among the causes of death occurring due to non-communicable diseases in the world. The majority of cardiovascular deaths are due to ischemic heart disease and cerebrovascular disease. Among the major risk factors, dyslipidemia is an important risk factor. Hence, the prevention of dyslipidemia results in the prevention of ischemic heart disease. Dyslipidemia can be corrected by drugs but more importantly, it can be prevented by lifestyle modification. Aim and Objectives: Our aim is to observe the impact of yoga on lipid parameters in different age groups. Materials and Methods: We included 54 subjects between the age group of 30 and 60 years for this study. They were categorized into two groups: Group I having ages between 30 and 45 years (n = 23) and Group II having ages between more than 45 years and <60 years (n = 31). The lipid parameters were measured afore of yoga training, at the end of 2 months and after 6 months of yogic practices. Statistical analysis was done using the SPSS version of 20.0. A P value of less than 0.05 is considered as statistically significant. Results: Our study revealed that yoga induces a decrease in total cholesterol, triglycerides, low-density lipoprotein cholesterol, and very LDL cholesterol and an increase in high-density lipoprotein cholesterol in both Group I and Group II subjects which were statistically significant. Conclusion: Yoga tends to improve dyslipidemia, a major risk factor for CVDs. A yoga lifestyle can be considered a preventive measure for CVDs.

ABSTRACT

Abstract Introduction The associations of low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein (HDL-C) with reduced saliva flow rates have not been previously reported. Objective The present study aimed to assess the association of cholesterolemia with reduced saliva flow rates in community-dwelling elderly subjects. Methods The present study analyzed 342 participants (170 males and 172 females aged between 78 and 79 years old). Unstimulated salivary flow rate (USFR) was assessed using a cotton roll method. Low-USFR was defined as 0.10 g/30 seconds. Stimulated salivary flow rate (SSFR) was assessed by having the participants chew tasteless gum for 3minutes. Low-SSFR was defined as 1.0 mL/minute. Blood samples were collected for the measurement of LDL-C, HDL-C, rheumatoid factor, hemoglobin A1c, and creatinine. To assess depression, the General Health Questionnaire 30 was used. A standardized questionnaire was completed, covering the current and previous medications of the participants and smoking status. We stratified the serum LDL-C levels of the participants as normal, moderate or severe hyper-LDL cholesterolemia and serum HDL-C levels as normal or hypo-HDL cholesterolemia. Multivariate logistic regression models were established and low-USFR or low-SSFR were set as dependent variables in the aforementioned models. Results After controlling for the effects of the other variables, the odds ratios (ORs) (95% confidence intervals [CIs]) for low-USFR were 2.25 (1.10-4.61) for moderate and 5.69 (1.55-20.8) for severe hyper-LDL cholesterolemia, while that of hypo-HDL cholesterolemia was 3.40 (1.33-8.69). Severe hyper-LDL cholesterolemia was also associated with low-SSFR with an OR of 3.89 (1.39-10.88). Conclusion Elderly patients with cholesterolemia have a risk of reduced salivary flow rate.

ABSTRACT

ABSTRACT Objective: The aim of the present study was to evaluate the prevalence of total cholesterol (TC) and low-density lipoprotein (LDL) alterations in children and adolescents in Brazil. Materials and methods: A systematic review and meta-analysis of prevalence. The search for articles was carried out in the databases: Medline (PubMed), Embase, Scientific Electronic Library Online (SciELO), Latin American and Caribbean Literature in Health Sciences (Lilacs). The meta-analysis was performed using the random effects model. The I² test was used to identify heterogeneity. Results: The present metanalysis revealed a significant prevalence of altered lipid profile in children and adolescents in Brazil. Regarding lipoprotein fractions, the prevalence of altered TC level was 27.47% (95% CI 24.36-30.82), and a smaller prevalence was observed for LDL cholesterol (19.29% - 95% CI 15.21-24.16). The models revealed high heterogeneity (I² = 99%; p < 0.01), however the precise source of it was not identified; although type of school, age group, year and the region of Brazil appeared to influence the estimations of altered lipid profiles. Conclusion: An important prevalence of lipid alterations was observed among Brazilian children and adolescents. Those results reinforce the importance of knowing the lipid profile of children and adolescents to perform early interventions for this public.

ABSTRACT

Background: The common cause of mortality in India is related to complications of cardiovascular disease which has direct relation with the hyperlipidemia, diabetes mellitus, and hypertension. Rosuvastatin more efficacious than other statins in lesser dosage and having good safety profile. Aim and Objective: The present study was undertaken to evaluate the safety, efficacy of rosuvastatin 10 mg daily dose versus alternate day dose in hyperlipidemia patients. Materials and Methods: A total of 50 individuals with hyperlipidemia were selected in this prospective open label research. Patients were grouped as Group D with rosuvastatin daily dose and Group A with alternate day dose. Fasting plasma lipid profile was assessed in both groups on the 1st, 4th, and 6th weeks. Results: There is significant reduction in total cholesterol, low-density lipoprotein cholesterol (LDL-C), triglycerides (TG), and elevation of high-density lipoprotein (HDL) after 4 weeks and 6 weeks of the treatment in both the groups compared to baseline. The mean percentage reduction of total cholesterol was by 24% and 21.60% (P < 0.05) in Group D and Group A, respectively. The mean percentage reduction of LDL-C was by 33.50% and 31% (P < 0.05) Group D and Group A, respectively. The mean percentage improvement of HDL-cholesterol was by 19.89% and 17.09% (P < 0.05) in Group D and Group A, respectively. The mean percentage of reduction of TG was by 36.70% and 41.33% (P < 0.05) Group D and Group A. Conclusion: Rosuvastatin 10 mg on alternate days had the same efficacy in lowering cholesterol levels as taking it every day, also it may be a cost-effective alternative without sacrificing therapeutic benefits or side effects.

ABSTRACT

La embolia por cristales de colesterol es efecto de la desestabilización de una placa de ateroma tras un evento desencadenante, produciendo la migración de cristales de colesterol hasta arteriolas periféricas, desencadenando un proceso inflamatorio endotelial; el espectro clínico varía desde ser asintomático hasta con un compromiso multiorgánico; la sospecha diagnóstica es principalmente clínica y será la biopsia de piel por su fácil accesibilidad, la que confirme el diagnóstico. El tratamiento es aún controvertido y no existe un consenso de las medidas terapéuticas para aplicar. A continuación, se presenta el caso de un paciente varón de 72 años de edad con una ateroembolia por cristales de colesterol en miembros inferiores, secundaria a una manipulación endovascular por angioplastia previa.


Cholesterol crystal embolism is the effect of the destabilization of an atherosclerotic plaque after a triggering event, producing the migration of cholesterol crystals to peripheral arterioles, triggering an endothelial inflammatory process; the clinical spectrum varies from being asymptomatic to having multiple organ involvement; diagnostic suspicion is mainly clinical and the skin biopsy will confirm the diagnosis due to its easy accessibility. The treatment is still controversial and there is no consensus on the therapeutic measures to apply. Below is the case of a 72-year-old male patient with atheroembolism due to cholesterol crystals in the lower limbs, secondary to endovascular manipulation by prior angioplasty.

ABSTRACT

Background Melanoma is one of the most aggressive and deadliest skin tumor. Cholesterol content in melanoma cells is elevated, and a portion of it accumulates into lipid rafts. Therefore, the plasma membrane cholesterol and its lateral organization might be directly linked with tumor development. ATP Binding Cassette A1 (ABCA1) transporter modulates physico-chemical properties of the plasma membrane by modifying cholesterol distribution. Several studies linked the activity of the transporter with a different outcome of tumor progression depending on which type. However, no direct link between human melanoma progression and ABCA1 activity has been reported yet. Methods An immunohistochemical study on the ABCA1 level in 110 patients-derived melanoma tumors was performed to investigate the potential association of the transporter with melanoma stage of progression and prognosis. Furthermore, proliferation, migration and invasion assays, extracellular-matrix degradation assay, immunochemistry on proteins involved in migration processes and a combination of biophysical microscopy analysis of the plasma membrane organization of Hs294T human melanoma wild type, control (scrambled), ABCA1 Knockout ( ABCA1 KO) and ABCA1 chemically inactivated cells were used to study the impact of ABCA1 activity on human melanoma metastasis processes. Results The immunohistochemical analysis of clinical samples showed that high level of ABCA1 transporter in human melanoma is associated with a poor prognosis. Depletion or inhibition ofABCA1 impacts invasion capacities of aggressive melanoma cells. Loss of ABCA1 activity partially prevented cellular motility by affecting active focal adhesions formation via blocking clustering of phosphorylated focal adhesion kinases and active integrin β3. Moreover, ABCA1 activity regulated the lateral organization of the plasma membrane in melanoma cells. Disrupting this organization, by increasing the content of cholesterol, also blocked active focal adhesion formation. Conclusion Human melanoma cells reorganize their plasma membrane cholesterol content and organization via ABCA1 activity to promote motility processes and aggressiveness potential. Therefore, ABCA1 may contribute to tumor progression and poor prognosis, suggesting ABCA1 to be a potential metastatic marker in melanoma.

ABSTRACT

Resumo Fundamento A incidência de eventos cardiovasculares em pacientes com doença cardíaca isquêmica crônica (DCIC) pode variar significativamente entre os países. Embora populoso, o Brasil é frequentemente sub-representado nos registros internacionais. Objetivos Este estudo teve como objetivo descrever a qualidade do atendimento e a incidência de eventos cardiovasculares em dois anos, além de fatores prognósticos associados em pacientes com DCIC em um centro terciário de saúde pública no Brasil. Métodos Pacientes com DCIC que compareceram para avaliação clínica no Instituto do Coração (São Paulo, Brasil) foram cadastrados e acompanhados por dois anos. O desfecho primário foi um composto de infarto do miocárdio (IM), acidente vascular encefálico ou morte. Um nível de significância de 0,05 foi adotado. Resultados De janeiro de 2016 a dezembro de 2018, 625 participantes foram incluídos no estudo. As características basais mostram que 33,1% eram mulheres, a idade mediana era de 66,1 [59,6 - 71,9], 48,6% tinham diabetes, 83,1% tinham hipertensão, 62,6% tinham IM prévio e 70,4% passaram por algum procedimento de revascularização. Em um acompanhamento mediano de 881 dias, 37 (7,05%) desfechos primários foram observados. Após ajustes, idade, acidente vascular encefálico prévio e colesterol LDL foram independentemente associados ao desfecho primário. Comparando a linha de base com o acompanhamento, os participantes relataram alívio da angina com base na escala da Sociedade Cardiovascular Canadense (SCC) de acordo com as seguintes porcentagens: 65,7% vs. 81,7% eram assintomáticos e 4,2% vs. 2,9% eram SCC 3 ou 4 (p < 0,001). Eles também relataram melhor qualidade na prescrição de medicamentos: 65,8% vs. 73,6% (p < 0,001). No entanto, não houve melhora no colesterol LDL ou no controle da pressão arterial. Conclusão O presente estudo mostra que pacientes com DCIC apresentaram uma incidência de 7,05% do desfecho primário composto em um período de dois anos, sendo a diminuição do colesterol LDL o único fator de risco modificável associado ao prognóstico.


Abstract Background The incidence of cardiovascular events in patients with chronic ischemic heart disease (CIHD) may vary significantly among countries. Although populous, Brazil is often underrepresented in international records. Objectives This study aimed to describe the quality of care and the two-year incidence of cardiovascular events and associated prognostic factors in CIHD patients in a tertiary public health care center in Brazil. Methods Patients with CIHD who reported for clinical evaluation at Instituto do Coração (São Paulo, Brazil) were registered and followed for two years. The primary endpoint was a composite of myocardial infarction (MI), stroke, or death. A significance level of 0.05 was adopted. Results From January 2016 to December 2018, 625 participants were included in the study. Baseline characteristics show that 33.1% were women, median age 66.1 [59.6 - 71.9], 48.6% had diabetes, 83.1% had hypertension, 62.6% had previous MI, and 70.4% went through some revascularization procedure. At a median follow-up (FU) of 881 days, we noted 37 (7.05%) primary endpoints. After adjustments, age, previous stroke, and LDL-cholesterol were independently associated with the primary endpoint. Comparing baseline versus FU, participants experienced relief of angina based on the Canadian Cardiovascular Society (CCS) scale according to the following percentages: 65.7% vs. 81.7% were asymptomatic and 4.2% vs. 2.9% CCS 3 or 4 (p < 0.001). They also experienced better quality of medication prescription: 65.8% vs. 73.6% (p < 0.001). However, there was no improvement in LDL-cholesterol or blood pressure control. Conclusion This study shows that CIHD patients had a two-year incidence of the primary composite endpoint of 7.05%, and the reduction of LDL-cholesterol was the only modifiable risk factor associated with prognosis.
