Longitudinal Trends in Severe Dyslipidemia in the Czech Population: The Czech MONICA and Czech Post-MONICA Study.

Background: Severe hypercholesterolemia is associated with an increase in the risk of developing atherosclerotic cardiovascular disease. The aim of this analysis was to assess longitudinal trends in severe dyslipidemia (defined as total cholesterol > 8 mmol/L or LDL-cholesterol > 5 mmol/L) in a representative population sample of the Czech Republic and to analyze the longitudinal trends in the basic characteristics of individuals with severe dyslipidemia. Methods: Seven independent cross-sectional surveys were organized in the Czech Republic to screen for major cardiovascular risk factors (from 1985 to 2015-2018). A total of 20,443 randomly selected individuals aged 25-64 years were examined. Results: The overall prevalence of severe dyslipidemia was 6.6%, with a significant downward trend from the fifth survey onwards (2000/2001). Over the study period of 30+ years, the individuals with severe dyslipidemia became older, increased in BMI, and did not change their smoking habits. Total cholesterol and non-HDL-cholesterol decreased significantly in both sexes throughout the duration of the study. Conclusions: Despite a significant improvement in lipids in the Czech Republic from 1985, substantially contributing to the decline in cardiovascular mortality, the number of individuals with severe dyslipidemia remained high, and in most cases, they were newly detected during our screening examinations and were thus untreated.

Longitudinal trends in blood pressure, prevalence, awareness, treatment, and control of hypertension in the Czech population. Are there any sex differences?

Background: Hypertension is the most common cardiovascular disease which substantially increases cardiovascular morbidity and mortality. Despite the broad availability of antihypertensive medication, control of hypertension is not satisfactory worldwide. Objective: The study aim was to assess longitudinal trends in blood pressure, prevalence, awareness, treatment, and control of hypertension in a representative population sample of the Czechia from 1985 to 2016/2017, focusing on sex differences. Methods: A total of 7,606 men and 8,050 women aged 25-64 years were screened for major CV risk factors in seven independent cross-sectional surveys run consistently in the same six country districts of the Czechia between 1985 and 2016/2017. The population samples were randomly selected. Results: Over a study period of 31/32 years, there was a significant decline in systolic and diastolic blood pressure in both sexes, whereas the prevalence of hypertension decreased only in women. There was an increase in hypertension awareness in both sexes over the entire study period with consistently higher rates in women. The proportion of individuals treated with antihypertensive drugs increased significantly in both sexes throughout the study, again with consistently higher rates in women. Control of hypertension increased significantly over the study period with consistently higher rates in women. The age-adjusted trends in blood pressure, prevalence, awareness, and treatment of hypertension were significantly different in men and women, always in favor of women. The age-adjusted trends in control of hypertension in treated patients were equally poor in both sexes. Conclusion: There are significant differences in longitudinal trends in blood pressure, prevalence, awareness, treatment, and control of hypertension between men and women, always in favor of women except for the control of hypertension in treated patients, where it is equally poor in both sexes.

Sex differences in hypertension. Do we need a sex-specific guideline?

Hypertension is the most prevalent cardiovascular disorder and the leading cause of death worldwide in both sexes. The prevalence of hypertension is lower in premenopausal women than in men of the same age, but sharply increases after the menopause, resulting in higher rates in women aged 65 and older. Awareness, treatment, and control of hypertension are better in women. A sex-pooled analysis from 4 community-based cohort studies found increasing cardiovascular risk beginning at lower systolic blood pressure thresholds for women than men. Hormonal changes after the menopause play a substantial role in the pathophysiology of hypertension in postmenopausal women. Female-specific causes of hypertension such as the use of contraceptive agents and assisted reproductive technologies have been identified. Hypertensive disorders in pregnancy are associated with increased risk of maternal, fetal, and neonatal morbidity and mortality, as well as with a greater risk of developing cardiovascular disease later in life. Hypertension-mediated organ damage was found to be more prevalent in women, thus increasing the cardiovascular risk. Sex differences in pharmacokinetics have been observed, but their clinical implications are still a matter of debate. There are currently no sufficient data to support sex-based differences in the efficacy of antihypertensive treatment. Adverse drug reactions are more frequently reported in women. Women are still underrepresented in large clinical trials in hypertension, and not all of them report sex-specific results. Therefore, it is of utmost importance to oblige scientists to include women in clinical trials and to consider sex as a biological variable.

Dietary interventions in blood pressure lowering: current evidence in 2020.

Dietary modification is one of the cornerstones in the treatment of arterial hypertension (AH). Current American and European guidelines recommend people to ingest fruit, vegetables, whole grains, and low­fat dairy products as well as to decrease the consumption of red meat, sugar, and trans fats. This review aimed to summarize available evidence on dietary patterns associated with lower blood pressure (BP). Research has shown that the Dietary Approach to Stop Hypertension (DASH) diet can lower BP equally effectively or even more significantly than some antihypertensive drugs. The Mediterranean diet also leads to a considerable reduction in BP. Vegans and vegetarians have been shown to have a lower prevalence of AH than omnivores. Caloric restriction may decrease BP in normotensive, prehypertensive, and hypertensive populations. Blood pressure can also be lowered by certain nutraceuticals (such as beetroot juice, magnesium, vitamin C, catechin­rich beverages, or soy isoflavones). Diet effects on BP are mediated by body weight loss, amelioration of inflammation, increased insulin sensitivity, and antihypertensive properties of some individual nutrients. There is robust evidence that vegetarian and vegan diets have the ability to reduce BP. The presence of the so-called floor effect makes these diets usable in normo- and prehypertensive people at high risk of developing AH. However, the dietary and nutraceutical approach to BP lowering cannot substitute drug treatment when the latter is needed.

An overview of rosuvastatin/ezetimibe association for the treatment of hypercholesterolemia and mixed dyslipidemia.

Introduction: Although statin therapy is a powerful lipid-lowering strategy, only one-fifth of statin users currently reach their lipid goals. In addition, statin treatment alone has relatively low efficacy in reducing other lipid fractions than low-density lipoprotein-cholesterol (LDL-C). In such cases, most guidelines recommend adding the cholesterol absorption inhibitor ezetimibe.Areas covered: This paper summarizes the main pharmacological characteristics of rosuvastatin and ezetimibe (mechanism of action, metabolism), their lipid-lowering and pleiotropic effects, with particular attention to the clinical effects of the combined drugs in hypercholesterolemia and mixed dyslipidemia patients (such as the ones affected by diabetes mellitus and Acquired Immune Deficiency Syndrome (AIDS)).Expert opinion: The additive effect of rosuvastatin and ezetimibe helps to reach lipid goals in a large number of high-risk patients, while avoiding some safety issues related to high dosages of intensive statin therapy. Patients with diabetes receive additional benefits from ezetimibe as they seem to absorb cholesterol more effectively than non-diabetic ones, because of increased NPC1L1 gene expression. Ezetimibe augments rosuvastatin triglyceride-lowering and anti-inflammatory effects, as well. Taking into account its excellent safety profile and lack of clinically relevant drug-drug interactions, the rosuvastatin/ezetimibe association is a valuable alternative to statin dose uptitration.

Social media for research, education and practice in rheumatology.

Online social networking offers numerous opportunities for continuing medical education, professional development, and scholarly collaboration. Available social media channels proved useful for expanding education and research perspectives, particularly in rapidly developing academic disciplines such as rheumatology. Although there are numerous advantages of social media, busy clinicians should be aware of some drawbacks related to misinformation, unethical promotion, and unprofessional behavior in globally expanding platforms. Filtering credible and expert-proven information by skilled users is, therefore, increasingly important. Enforcing ethical norms and advancing professional etiquette in the field is strongly advisable. This article overviews the advantages and shortcomings of social media and reflects on available platforms for education and research in rheumatology.

Safety and tolerability of injectable lipid-lowering drugs: an update of clinical data.

INTRODUCTION: Cardiovascular (CV) diseases are the leading cause of death and disability in the developed countries. Lipid-lowering therapy is a cornerstone of the CV risk modification strategy. The first line treatment for hyperlipidemia is statins, which decrease low-density lipoprotein cholesterol (LDL-C) by 30-50% and proportionally reduce the CV events. However, they are not always enough to achieve LDL-C goals in many patients, and some patients are statin intolerant. For this reason, new powerful injectable lipid-lowering drugs have been developed. AREAS COVERED: The aim of this narrative review was to summarize the more recent clinical data on safety and tolerability of injectable lipid-lowering drugs. After an attentive literature search, the authors resumed here information on proprotein convertase subtilisin/kexin 9 inhibitors (evolocumab and alirocumab), small interfering RNA molecule inclisiran, antisense oligonucleotides (mipomersen, volanesorsen, ISIS 681257), and drugs targeting angiopoietin-like protein 3 (evinacumab, IONIS-ANGPTL3Rx). EXPERT OPINION: Injectable lipid-lowering therapy for patients at high risk for CV disease complications or with severe inherited hypercholesterolemias can be an important element of the available therapeutic armamentarium. Clinical data prove the favorable risk-benefit profile of evolocumab, alirocumab, and inclisiran. Mipomersen, volanesorsen, ISIS 681257, evinacumab, and IONIS-ANGPTL3Rx safety is currently less extensively studied, especially in patients with comorbidities and polypharmacotherapy.

Safety and tolerability of available urate-lowering drugs: a critical review.

INTRODUCTION: Urate-lowering therapy (ULT) is the cornerstone of gout management, which is a widespread chronic illness characterized by hyperuricemia, arthropathy, tophus development, and urolithiasis. Since asymptomatic increased serum urate levels are associated with a higher risk of cardiovascular, renal and metabolic disorders, a larger use of ULTs in the general population is expected in the near future. AREAS COVERED: This review will focus on the safety and tolerability profile of the available urate-lowering drugs: xanthine oxidase inhibitors (XOIs), uricosuric agents and injectable uricases. EXPERT OPINION: Older drugs for ULT like allopurinol are well studied and extensively described from typical adverse effects (mild skin rash) to unusual fatal reactions, while febuxostat seems to be overall well tolerated. More evidence is required to define the safety profile of topiroxostat, arhalofenate, tranilast, and sulfinpyrazone. Furthermore, there are some unanswered questions about the pharmacological interactions of probenecid and the hepatotoxicity of benzbromarone. Despite a limited use in clinical practice, combination therapy with lesinurad or verinurad and XOI is not frequently accompanied by side effects. Rasburicase and pegloticase are usually well tolerated with some specific exceptions. Before prescribing UL drugs, physicians should take into account their safety profile tailoring the treatment on the patient characteristics.

ASIT as the component of bronchial asthma's therapy can improve the adherence to the treatment.

OBJECTIVE: The aim: To compare the treatment adherence of patients with Bronchial Asthma (BA) receiving basic treatment and its combination with allergen-specific immunotherapy. PATIENTS AND METHODS: Materials and methods: The study included 104 patients aged from 18 to 50 with BA. All patients were divided into two groups. The main group (MG) consisted of 51 patients receiving basic medical treatment and ASIT. 38 of them received subcutaneous ASIT and 13 patients received sublingual ASIT. The comparative group (CG) consisted of 53 patients who received only basic therapy. The patients' observation duration was for a year. RESULTS: Results: All patients were done the computer spirometry with a bronchodilation test, determination of the total IgE level, questionnaires (quality of life, control of asthma, adherence to treatment). Also the major and minor component of allergy house dust mites and specific IgG4 were determined in patients of main groups. After 12 months of observation in both groups the spirometry rates improved (the main group result was 16.9%, the control group - was 12.8%). The indicators of asthma's control also increased (MG by 28%, in CG - 21%, (p <0,05)). After individual conversations and training the patients improved and adherence to the treatment too. In the beginning of our research the mean level in MG was 3.2 ± 0.3 points, in - CG-3.3 ± 0.2 points (p> 0.05), after 12 months it increased to 6.3 ± 0.2 points in MG vs 5. 8 ± 0.1 points in CG (p <0.05). CONCLUSION: Conclusion: Patients' combining basic therapy with SIT had significantly better results of the overall BA's controllability compared to the patients' receiving only basic therapy.

Estimation of cardiosurgical intervention risk according to EuroSCORE in patients with acute coronary syndrome and different gallbladder conditions before coronary artery bypass grafting.

INTRODUCTION: Estimation of cardiosurgical intervention risk according to EuroSCORE is an important aspect of cardiosurgery. EuroSCORE allows prediction of the probability of a post-operational fatal outcome. AIM: To estimate the influence of gallbladder condition on the prognosis after coronary artery bypass grafting (CABG) and and the interactions between metabolic background and cardiosurgical intervention risk. MATERIAL AND METHODS: We investigated data of 98 patients with unstable angina pectoris or acute myocardial infarction before planned CABG. These patients were divided into the following groups according to their gallbladder condition: intact bladder; bile sludge or cholesterosis; bent gallbladder body; gallbladder neck deformations or cholecystitis; cholelithiasis; history of cholecystectomy. RESULTS: The mean cardiosurgical intervention risk score according to the EuroSCORE system in our patients was 6.03 ±0.62%. It was significantly higher in patients with low serum bilirubin levels. There were direct correlations between the risk score result and presence of left ventricular dilatation (r = 0.31, p < 0.05) and fasting glucose level (r = 0.82, p < 0.01), as well as with means of other parameters, i.e., left atrial dimension, right ventricular size, grade of stenosis of anterior interventricular branch of left coronary artery, serum levels of total cholesterol, ß-lipoproteins, bilirubin and potassium. CONCLUSIONS: These correlations suggest that the EuroSCORE results estimated before surgery may be used as a simple informative prognostic criterion of intra-operational cardiac mortality and also as a marker of structural and functional heart condition and metabolic background. However, these correlations were different in patients with different gallbladder conditions.
