The Role of Galectin-3 Levels for Predicting Paroxysmal Atrial Fibrillation in Patients with Embolic Stroke of Undetermined Source.

Background/Objectives: Paroxysmal atrial fibrillation (PAF) is an important cause that is thought main potential factor in Embolic stroke of undetermined source (ESUS). Extended Holter ECG is an expensive and time-consuming examination. It needs another tools for predicting PAF in ESUS patients. In this study, serum galectin-3 levels, ECG parameters (PR interval, P wave time and P wave peak time) LA volume index, LA global peak strain and atrial electromechanical conduction time values were investigated for predicting PAF. Methods: 150 patients with ESUS and 30 volunteers for the control group were recruited to study. 48-72 h Holter ECG monitoring was used for detecting PAF. Patients were divided into two groups (ESUS + PAF and ESUS-PAF) according to the development of PAF in Holter ECG monitoring. Results: 30 patients with ESUS whose Holter ECG monitoring showed PAF, were recruited to the ESUS + PAF group. Other 120 patients with ESUS were recruited to the ESUS-PAF group. PA lateral, PA septum, and PA tricuspid were higher in the ESUS + PAF group (p < 0.001 for all). Serum galectin-3 levels were significantly higher in ESUS + PAF than in ESUS-PAF and control groups (479.0 pg/mL ± 435.8 pg/mL, 297.8 pg/mL ± 280.3 pg/mL, and 125.4 ± 87.0 pg/mL, p < 0.001, respectively). Serum galectin-3 levels were significantly correlated with LAVI, PA lateral, and global peak LA strain (r = 0.246, p = 0.001, p = 0.158, p = 0.035, r = -0.176, p = 0.018, respectively). Conclusion: Serum galectin-3 levels is found higher in ESUS patients which developed PAF and Serum galectin-3 levels are associated LA adverse remodeling in patients with ESUS.

Is There a Relationship Between Metabolic Equivalence and the SYNTAX Score as Strong Prognostic Markers?

OBJECTIVE: The metabolic equivalent (MET) and Synergy between Percutaneous Coronary Intervention with TAXUS and Cardiac Surgery (SYNTAX) score are two parameters with known cardiovascular prognostic significance. In this study, we aimed to investigate the direct relationship between MET and SYNTAX score in patients with chronic coronary syndrome (CCS). METHOD: This retrospective study included 200 patients over 18 years of age who underwent coronary angiography and had a positive exercise electrocardiography test result. Patients were divided into two groups: Group 1 with a low SYNTAX score and Group 2 with a medium-high SYNTAX score. MET values were then compared between these groups. RESULTS: Baseline demographic characteristics and laboratory values were similar between the groups. The mean MET values in the low and medium-high SYNTAX score groups were 9.36 ± 2.38 and 8.78 ± 2.43, respectively. No statistical difference was observed (P = 0.086). Additionally, there was no statistical difference between the two groups in terms of MET values being 10 ≤ or 10 > (P = 0.172). CONCLUSION: The main conclusion of our study is that there is no correlation between the SYNTAX score and functional MET value in CCS.

Improvement in endothelial function in hypertensive patients after Ramadan fasting: effects of cortisol.

BACKGROUND: There are studies on the effects of Ramadan fasting (RF), which is one of the intermittent fasting diets, on both hypertension and endothelial function. However, the relationship between possible improvements in endothelial function and blood pressure after RF is not clear. In this study, we aimed to evaluate the effects of RF on blood pressure and endothelial dysfunction in patients with arterial hypertension (HT). METHODS: : Sixty-four HT patients, aged 45-65, who were followed up in the Cardiology Department of Kayseri City Hospital and fasted during Ramadan between 13 April and 13 May 2021 with their self-consents were enrolled to study. Body mass index (BMI), blood pressure, and flow-mediated dilatation (FMD) were assessed before and after Ramadan. Also, 5 mL venous blood samples were taken between 8:00 and 8:30 a.m. from all participants to assess cortisol, C-reactive protein (CRP), and other laboratory data. RESULTS: : In patients, FMD values were found to be higher after Ramadan compared to values before the fasting period (p < 0.001). CRPand cortisol levels decreased after fasting, and the decrease in CRP (95% CI for B = -1.685 - -0.334, p = 0.009) and cortisol levels (95% CI for B = -0.392 - 0.092, p = 0.039) were determined as the predictive factors for FMD after RF. DISCUSSION: Endothelial functions as determined by FMD improved after 30 days of intermittent fasting. The decreased CRP and cortisol levels may contribute to the improvement in FMD after RF.

Improvement in Blood Pressure After Intermittent Fasting in Hipertension: Could Renin-Angiotensin System and Autonomic Nervous System Have a Role? / Melhora da Pressão Arterial após Jejum Intermitente na Hipertensão: O Sistema Renina-Angiotensina e o Sistema Nervoso Autônomo Podem Funcionar?

BACKGROUND: Although it has been reported that the intermittent fasting (IF) diet has positive effects on heart health and improvement in blood pressure, it has not been sufficiently clarified how it could have these positive effects yet. OBJECTIVE: We aimed to evaluate the effects of IF on the autonomic nervous system (ANS) and renin-angiotensin system (RAS), which are closely related to blood pressure. METHODS: Seventy-two hypertensive patients were included in the study, and the data of 58 patients were used. All the participants fasted for about 15-16 hours for 30 days. Participants were evaluated with 24-hour ambulatory blood pressure monitoring and Holter electrocardiography before and after IF; also, 5 ml venous blood samples were taken for assessment of Serum angiotensin I (Ang-I) and angiotensin II (Ang-II) levels and angiotensin-converting enzyme (ACE) activity. For data analysis, the p-value <0.05 was accepted as significant. RESULTS: Compared to pre-IF, a significant decrease was observed in the patients' blood pressures in post-IF. An increase in high-frequency (HF) power and the mean root square of the sum of squares of differences between adjacent NN intervals (RMSSD) were observed after the IF protocol (p=0.039, p=0.043). Ang-II and ACE activity were lower in patients after IF (p=0.034, p=0.004), and decreasing Ang-II levels were determined as predictive factors for improvement of the blood pressure, like the increase in HF power and RMSSD. CONCLUSION: The present findings of our study demonstrated an improvement in blood pressure and the relationship of blood pressure with positive outcomes, including HRV, ACE activity, and Ang-II levels after the IF protocol.

FUNDAMENTO: Embora tenha sido relatado que a dieta de jejum intermitente (JI) tem efeitos positivos na saúde do coração e na melhora da pressão arterial, ainda não foi suficientemente esclarecido como poderia ter esses efeitos positivos.Objetivo: Nosso objetivo foi avaliar os efeitos do JI no sistema nervoso autônomo (SNA) e no sistema renina-angiotensina (SRA), que estão intimamente relacionados à pressão arterial. MÉTODOS: Setenta e dois pacientes hipertensos foram incluídos no estudo, e os dados de 58 pacientes foram usados. Todos os participantes jejuaram por cerca de 15-16 horas por 30 dias. Os participantes foram avaliados com monitorização ambulatorial da pressão arterial de 24 horas e eletrocardiograma Holter antes e após o JI; também, amostras de sangue venoso de 5 ml foram coletadas para avaliação dos níveis séricos de angiotensina I (Ang-I) e angiotensina II (Ang-II) e da atividade da enzima conversora de angiotensina (ECA). Para análise dos dados, o valor de p < 0,05 foi aceito como significativo. RESULTADOS: Comparado ao pré-JI, observou-se queda significativa nas pressões arteriais dos pacientes no pós-JI. Um aumento na potência de alta frequência (AF) e na raiz quadrada média da soma dos quadrados das diferenças entre intervalos NN adjacentes (RMSSD) foram observados após o protocolo JI (p=0,039, p=0,043). A Ang-II e a atividade da ECA foram menores em pacientes após JI (p=0,034, p=0,004), e níveis decrescentes de Ang-II foram determinados como fatores preditivos para melhora da pressão arterial, como o aumento da potência de AF e RMSSD. CONCLUSÃO: Os presentes achados de nosso estudo demonstraram uma melhora na pressão arterial e a relação da pressão arterial com resultados positivos, incluindo VFC, atividade da ECA e níveis de Ang-II após o protocolo JI.

Assessment of a New Electrocardiographic Marker for the Diagnosis of Myocardial Infarction With Non-obstructive Coronary Arteries.

Myocardial infarction with non-obstructive coronary arteries (MINOCA) is clinically defined as myocardial infarction in the absence of obstructive atherosclerosis on coronary angiography. Diagnosis may require multiple diagnostic tools in addition to standard coronary angiography, including cardiac imaging or provocative tests, according to clinical suspicion. We assessed the usefulness of the DETERMINE (Defibrillators to Reduce Risk by Magnetic Resonance Imaging Evaluation) score for distinguishing patients with MINOCA from those with non-ST segment elevation myocardial infarction with obstructive coronary artery disease (NSTEMI-CAD) in a single-center observational study. The patients were divided into two groups according to coronary angiography findings. The study included 277 patients: 227 with NSTEMI-CAD and 50 with MINOCA. The DETERMINE score (6.1 ± 3.7 vs 1.9 ± 2.1, P<.001) was significantly higher in the NSTEMI-CAD than MINOCA group. Logistic regression analysis revealed that the DETERMINE score (OR=0.591, P<0.001) was an independent predictor of MINOCA. The incidence of diabetes mellitus and glucose levels were significantly higher in the NSTEMI-CAD group; however, ejection fraction was significantly higher in the MINOCA group (P<0.05). Our findings suggest that the DETERMINE score constitutes a simple and inexpensive tool for the assessment of MINOCA.

An Evaluation of Aspirin Treatment Preferences ORIGINAL INVESTIGATION of Physicians in Hypertensive Patients in Terms of Current Guidelines: A Subgroup Analysis of the ASSOS Trial in Turkey.

BACKGROUND: The Appropriateness of Aspirin Use in Medical Outpatients: A Multicenter, Observational Study trial has been the largest study ever conducted among patients in Turkey regarding aspirin treatment. In the subgroup analysis of the hypertensive group of the Appropriateness of Aspirin Use in Medical Outpatients: A Multicenter, Observational Study trial, we aimed to evaluate the physicians' adherence to current guidelines regarding their aspirin treatment preferences. METHODS: The Appropriateness of Aspirin Use in Medical Outpatients: A Multicenter, Observational Study trial is a cross-sectional and multicenter study conducted among 5007 consecutive patients aged ≥18 years. The study population consisted of outpatients on aspirin treatment (80-300 mg). The patient data were obtained from 30 different cardiology clinics of 14 cities from all over Turkey. In this subgroup analysis, patients were divided into 2 groups: the hypertensive group (n=3467, 69.3%) and the group without hypertension (n=1540, 30.7%) according to the 2018 European Society of Cardiology/ European Society of Hypertension Guidelines for the Management of Arterial Hypertension. RESULTS: Aspirin use for primary prevention was higher in patients with hypertension compared to patients without hypertension [328 (21.3%); 1046 (30.2%); P < .001]. Treatment with a dose of 150 mg aspirin (n=172, 5%) was mostly preferred by internists for hypertensive patients (n =226, 6.5%); however, a daily dose of 80-100 mg aspirin therapy (n=1457, 94.6%) was mostly prescribed by cardiologists (n=1347, 87.5%) for patients without hypertension. CONCLUSION: Aspirin was found to be used commonly among patients with hypertension for primary prevention despite the current European Society of Cardiology Arterial Hypertension Guideline not recommending aspirin for primary prevention in patients with hypertension.

Inappropriate Use of Aspirin in Real-Life Cardiology Practice: Results from the Appropriateness of Aspirin Use in Medical Outpatients: A Multicenter, Observational Study (ASSOS) Study.

BACKGROUND: Indications and appropriateness of aspirin use have not been well investigated in Turkey. AIMS: To investigate the prescription patterns and appropriateness of aspirin in a real-world clinical setting. STUDY DESIGN: Cross-sectional study. METHODS: The Appropriateness of Aspirin Use in Medical Outpatients: A Multicenter, Observational Study (ASSOS) is a cross-sectional and multicenter study that included 5007 consecutive patients aged 18 or over who presented to 30 different cardiology outpatient clinics from 14 cities throughout Turkey. Only patients using aspirin (80-325 mg) were included. The study population was divided into 2 groups regarding the use of aspirin: primary prevention (PP) group and secondary prevention (SP) group. The indication of aspirin use was evaluated following the 2016 European Society of Cardiology (ESC) and the 2016 United States Preventative Services Task Force (USPTF) guidelines in the PP group. RESULTS: A total of 5007 patients (mean age 62.15 ± 11.05, 39% female) were enrolled. The PP group included 1132 (22.6%) patients, and the SP group included 3875 (77.4%) patients. Of the 1132 patients, inappropriate use of aspirin was determined in 100% of the patients according to the ESC guidelines, and 71% of the patients according to the USPTF guidelines. Multivariate logistic regression analysis showed age OR: 0.98 CI (0.97-0.99) P = .037, smoking OR: 0.60 CI (0.44-0.82) P = .001, heart failure OR: 2.11 CI (1.14-3.92) P = .017, hypertension OR: 0.51 CI (0.36-0.74) P < .001, diabetes mellitus OR: 0.34 CI (0.25-0.47) P < .001, oral anticoagulant use OR: 3.01 CI (1.10-8.25) P = .032, and female sex OR: 2.73 CI (1.96-3.80) P < .001 were independent predictors of inappropriate aspirin use in PP patients. CONCLUSION: Although there are considerable differences between the USPTF and the ESC guidelines with respect to recommendations for aspirin use in PP, inappropriate use of aspirin in Turkey is frequent in real-world practice for both guidelines. Besides, heart failure, oral anticoagulant use, and the female sex of the patients were independent predictors of inappropriate use of aspirin.

Evaluation of homocystein and asymmetric dimethyl arginine levels in patients with coronary slow flow phenomenon.

BACKGROUND: Previous studies have demonstrated that homocysteine and asymmetric dimethyl arginine (ADMA) levels were strongly associated with cardiovascular diseases including coronary artery disease. The aim of this study was to investigate the role of plasma homocysteine and ADMA levels in the pathogenesis of coronary slow flow (CSF) phenomenon. METHODS: Twenty-three patients with CSF and 25 controls with normal coronary flow were included in this study. The quantitative measurement of coronary blood flow was performed using the thrombolysis in myocardial infarction frame count method. Plasma homocysteine and ADMA levels were determined using enzymatic assays from venous blood samples. RESULTS: The patients with CSF had significantly higher plasma homocysteine levels than controls (16.2 ± 7.6 vs. 12.2 ± 2.2 µM/L; p = 0.023). The uric acid levels were significantly higher in CSF group than controls (5.4 ± 1.1 vs. 4.6 ± 0.9 mg/dl; p = 0.011). Plasma ADMA levels were also higher in the CSF group; however, this was not statistically significant (0.6 ± 0.1 vs. 0.5 ± 0.2 µM/L; p = 0.475). CONCLUSIONS: Increased homocysteine and uric acid levels may play an important role in the pathogenesis of CSF. Further large scale studies are required to determine the relationship between ADMA levels and CSF.

Design and rationale for the ASSOS study: Appropriateness of aspirin use in medical outpatients a multicenter and observational study.

OBJECTIVE: The aim of this study was to describe the current status of aspirin use and the demographic characteristics of patients on aspirin for primary and secondary prevention of cardiovascular diseases. METHODS: The Appropriateness of Aspirin Use in Medical Outpatients: A Multicenter, Observational Study (ASSOS) trial was a multicenter, cross-sectional, and observational study conducted in Turkey. The study was planned to include 5000 patients from 14 cities in Turkey. The data were collected at one visit, and the current clinical practice regarding aspirin use was evaluated (ClinicalTrials.gov number NCT03387384). RESULTS: The study enrolled all consecutive patients who were admitted to the outpatient cardiology clinics from March 2018 until June 2018. Patients should be at least 18 years old, have signed written informed consent, and on aspirin (80-325 mg) therapy within the last 30 days. Cardiologists from the hospital participates in the study. Patients were divided into 2 categories according to presence or absence of atherosclerotic cardiovascular disease, namely secondary prevention group and primary prevention group, respectively. The appropriate use of aspirin in the primary and secondary prevention groups was assessed according to the European Society of Cardiology guidelines and US Preventive Services Task Force. The patients' gastrointestinal bleeding risk factors and colorectal cancer risk were evaluated. CONCLUSION: The ASSOS registry will be the most comprehensive and largest study in Turkey evaluating the appropriateness of aspirin use. The results of this study help understand the potential misuse of aspirin in a real-world setting.

Rationale, Design, and Methodology of the APOLLON trial: A comPrehensive, ObservationaL registry of heart faiLure with midrange and preserved ejectiON fraction.

OBJECTIVE: Although almost half of chronic heart failure (HF) patients have mid-range (HFmrEF) and preserved left-ventricular ejection fraction (HFpEF), no studies have been carried out with these patients in our country. This study aims to determine the demographic characteristics and current status of the clinical background of HFmrEF and HFpEF patients in a multicenter trial. METHODS: A comPrehensive, ObservationaL registry of heart faiLure with mid range and preserved ejectiON fraction (APOLLON) trial will be an observational, multicenter, and noninterventional study conducted in Turkey. The study population will include 1065 patients from 12 sites in Turkey. All data will be collected at one point in time and the current clinical practice will be evaluated (ClinicalTrials.gov number NCT03026114). RESULTS: We will enroll all consecutive patients admitted to the cardiology clinics who were at least 18 years of age and had New York Heart Association class II, III, or IV HF, elevated brain natriuretic peptide levels within the last 30 days, and an left ventricular ejection fraction (LVEF) of at least 40%. Patients fulfilling the exclusion criteria will not be included in the study. Patients will be stratified into two categories according to LVEF: mid-range EF (HFmrEF, LVEF 40%-49%) and preserved EF (HFpEF, LVEF ≥50%). Regional quota sampling will be performed to ensure that the sample was representative of the Turkish population. Demographic, lifestyle, medical, and therapeutic data will be collected by this specific survey. CONCLUSION: The APOLLON trial will be the largest and most comprehensive study in Turkey evaluating HF patients with a LVEF ≥40% and will also be the first study to specifically analyze the recently designated HFmrEF category.

Evaluation of ghrelin levels and endothelial functions in patients with coronary slow flow phenomenon.

BACKGROUND: Ghrelin has recently been reported to have beneficial effects on cardiac contractile functions and coronary blood flow. The main purpose of this study was to investigate the role of ghrelin in the pathogenesis of coronary slow flow (CSF) together with endothelial functions. METHODS: Twenty-five patients having normal coronary arteries with CSF and 25 controls with normal coronary flow were included into the study. The quantitative measurement of coronary blood flow was performed for each coronary artery using the thrombolysis in myocardial infarction (TIMI) frame count (TFC) method. Ghrelin levels were measured using the enzyme-linked immunosorbent assay method from venous blood samples. Endothelial functions were evaluated from the brachial artery with the flow-mediated dilation (FMD) and nitrate-related dilation methods. RESULTS: There was a significant difference in terms of mean TFC values between the control and CSF groups (p < 0.001 for all coronary arteries). The mean FMD percentage among patients with CSF was lower than that of the control group (5.9 ± 0.8 vs. 10.7% ± 1.1%; p < 0.001). A moderate negative correlation was observed between the FMD percentages and the TFCs. There was no relationship between the TFC and ghrelin levels. CONCLUSION: Plasma ghrelin levels seem to be uninfluential while impaired endothelial functions play an important role in the etiopathogenesis of CSF.

Relationship between serum 25-hydroxyvitamin D levels and the SYNTAX score in patients with acute coronary syndrome.

OBJECTIVE: The extent of severity and complexity of coronary artery disease (CAD) in patients presenting with ST-segment elevation myocardial infarction (STEMI) and non-STEMI (NSTEMI) and possible correlations between serum 25-hydroxyvitamin D (25(OH)D) have not yet been adequately studied. We evaluated the relationship between 25(OH)D levels and the burden of CAD as assessed by the SYNTAX score (SXscore) in patients with acute coronary syndrome (ACS) including STEMI and NSTEMI. METHODS: After exclusion, a total of 113 patients who were admitted to our hospital due to ACS and who were referred for undergoing coronary angiography were prospectively included. Their mean age was 63.3±18.5 years, and 80.5% of them were men. In total, 44.2% of the patients had NSTEMI and the remaining had STEMI. Blood samples were drawn at admission to evaluate serum 25(OH)D levels. CAD severity was assessed using the SXscore. Patients were classified as having low (SXscore ≤22) or high (SXscore >22) SXscores. Pearson's and Spearman's correlation coefficients were used to examine the relationship between serum 25(OH)D levels and the SXscore. RESULTS: 25(OH)D levels were significantly lower in the group with a high SXscore than in the group with a low SXscore (21.0±8.0 vs. 16.7±6.8, p=0.005). Correlation analysis showed a significant correlation between 25(OH)D levels and the SXscore. Multiple linear regression (MLR) analysis was used to determine the significance of the relationship between the SXscore and 25(OH)D, parathyroid hormone, and C-reactive protein levels and eGFR. MLR analysis revealed that only 25(OH)D levels (coefficient beta, -0.217, p=0.029) was significantly associated with the severity of CAD. CONCLUSION: The present study showed that serum 25(OH)D levels were significantly lower in patients with STEMI/NSTEMI and that low serum 25(OH)D levels were significantly correlated with CAD severity and extent.

Chylous ascites after resection of giant adrenocortical carcinoma.

Postoperative chylous ascites (PCA) is a rare clinical state that occurs during abdominal surgery. Despite its rarity, the need to diagnose and treat PCA is increasing in importance with the increased number of wide resections and lymph node dissections being performed and the serious consequences of treatment. Here we describe the PCA complications we observed after resection for treating a case of giant adrenocortical carcinoma and we have the brief review of the PCA complication.

Degenerative arthritis of pseudoarticulation between the os peroneum and cuboid: a rare cause of lateral foot pain.

The painful os peroneum syndrome is widely recognized. It is often the result of trauma. However degenerative changes between the os peroneum and the articular facet is much rarer and we could only find two other case reports in the literature. This report concerns a middle aged woman with chronic plantar-lateral foot pain and a limp secondary to degenerative changes between the os peroneum and its articular facet with cuboid. The aim of this study is to remind to orthopaedic surgeons about painful os peroneum syndrome and to highlight the rarity of our case. In our case the mid term result of the excision of the os peroneum with painful articulation appear good, providing symptomatic pain relief with little alteration in the function of the foot.

γ-Glutamyl transferase activity and the burden of coronary atherosclerosis in patients with ST-segment elevation myocardial infarction.

The relationship between extent, severity, and complexity of coronary artery disease (CAD) in patients with ST-segment elevation myocardial infarction (STEMI) and serum γ-glutamyl transferase (GGT) activity has not been adequately studied. We evaluated the relationship between GGT activity and the burden of CAD as assessed by SYNTAX score (SXscore) in patients with STEMI. A total of 243 patients (age 67.1 ± 8.6, 77.4% male) with STEMI were divided into 2 groups. Low- and high-SXscore groups were defined as SXscore <22 and ≥22, respectively. Admission GGT activities were similar between low- and high-SXscore groups (32 ± 17 vs 33 ± 18; P = .625), and there was no significant correlation between GGT activity and SXscore. Although there was an association between high SXscore and major adverse cardiovascular events, as expected, our results did not demonstrate any relationship between admission GGT activities and complexity and extent of the coronary lesions in patients with STEMI.

Serum gamma glutamyl transferase and alanine transaminase concentrations predict endothelial dysfunction in patients with non-alcoholic steatohepatitis.

PURPOSE: Cardiovascular diseases are the leading cause of death in patients with non-alcoholic steatohepatitis (NASH). We aimed to investigate the presence of endothelial dysfunction and whether serum concentrations of liver enzymes may reflect the severity of such an endothelial dysfunction in patients with NASH. METHODS: Fifty patients with NASH diagnosed by liver biopsies and 30 healthy controls were included. Blood samples after fasting were harvested for measurements of glucose, insulin, cholesterol, triglyceride, and liver enzymes. All patients underwent transthoracic echocardiography and brachial and carotid artery Doppler ultrasonography to evaluate flow-mediated dilatation (FMD) and carotid artery intima-media thickness (CIMT). RESULTS: Patients with NASH had impaired FMD (4.9 ± 2.8% to 9.3 ± 4.4%, P < 0.001) and higher CIMT (0.79 ± 0.16 mm to 0.64 ± 0.11 mm, P < 0.001) when compared with healthy controls. Linear regression analyses revealed that serum concentrations of gamma glutamyl transferase (GGT) and alanine transaminase (ALT) were associated with FMD and CIMT. CONCLUSIONS: Patients with NASH have impaired FMD and increased CIMT when compared with healthy controls. In patients with NASH, serum concentrations of GGT and ALT might have a predictive value for FMD and CIMT.

[The effect of statin treatment on inflammation in patients with metabolic syndrome]. / Metabolik sendromlu hastalarda statin tedavisinin inflamasyon üzerine etkisi.

OBJECTIVES: Inflammation plays an important role in the pathogenesis of metabolic syndrome (MS). We investigated the effect of fluvastatin treatment on inflammatory markers in patients with MS. STUDY DESIGN: The study included 47 patients (36 females; 11 males; mean age 55+/-8 years) with MS. The diagnosis of MS was based on the presence of at least three criteria of the NCEP ATP III guidelines. All the patients received 80 mg fluvastatin treatment for six weeks. Laboratory parameters were measured before and after treatment, and flow cytometric analysis of peripheral blood leukocytes was performed. The results were compared with those of 47 age- and sex-matched healthy controls (33 females, 14 males; mean age 52+/-8 years). RESULTS: Fluvastatin treatment resulted in significant decreases in levels of total cholesterol, LDL cholesterol, triglyceride (p<0.005), and C-reactive protein (p<0.05). Thirty-three patients (70.2%) had insulin resistance, which remained unchanged following treatment. Flow cytometric analysis after treatment showed significant decreases in total lymphocytes, and in surface antigens of CD16+56 and CD8+(CD28+) on leukocytes, CD11c on granulocytes, and a significant increase in the CD4/CD8 ratio (p<0.05). Compared to the control group, the mean baseline values of fluorescence density (FD) of CD14, CD11b, CD11c, and CD63 on monocytes, and CD11b and CD11c on granulocytes were significantly higher in patients with MS (p<0.05). Following fluvastatin treatment, there were significant decreases in the mean FD of CD3 on lymphocytes, and of CD11b and CD11c on both monocytes and granulocytes (p<0.05); of these, all FD values were similar to those in the control group (p>0.05). CONCLUSION: Our data demonstrate that inflammation may have a significant role in the pathogenesis of MS and that this effect can be controlled with statin treatment.
