Neutrophil- and Platelet- to Lymphocyte Ratio in Patients with Euthyroid Hashimoto's Thyroiditis.

BACKGROUND: Hashimoto's thyroiditis (HT) is the most prevalent autoimmune thyroid disorder. Both neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are reported to be increased in various inflammation-related diseases, but their clinical significance in HT remains unclear. OBJECTIVES: The aim of this study was to investigate the relationship between thyroid autommunity and NLR and PLR as markers of systemic inflammation in HT. METHODS: In this study, we evaluated 145 women with HT and 60 age-matched healthy controls. We compared the PLR and the NLR of HT patients with controls and the correlation between the NLR, PLR, and C-reactive protein (CRP), thyroid-stimulating hormone (TSH) and thyroid antibody titers in the patient group. Also we compared the PLR and the NLR of HT patients that received levothyroxine with those who did not receive levothyroxine RESULTS: There were no significant differences between patient and control groups in terms of overall leukocyte counts, neutrophil counts, and other laboratory tests. In the patient group lymphocyte counts were lower while the platelet counts, NLR (2.29±0.65 vs1.68±0.40), PLR (164.95±55.14 vs106.88±32.19) were higher than those of the control (p<0.001 for all comparisons). CONCLUSION: In this study we found that NLR and PLR were higher in euthyroid Hashimoto patients than in a healthy control group. NLR and PLR are likely non-specific indicators of immune disorder and their implications for HT and other conditions remain to be elucidated.

Evaluation of Daily Blood Pressure Alteration in Subclinical Hypothyroidism.

BACKGROUND: Subclinical hypothyroidism is the most common thyroid dysfunction in the general population. The relationship between overt thyroid dysfunction and hypertension is generally understood. Besides high blood pressure, non-dipper hypertension is known to increase cardiovascular risk. Our aim is to investigate daily blood pressure changes and the frequency of non-dipping patterns in patients with subclinical hypothyroidism. METHODS: Forty-nine patients without hypertension with subclinical hypothyroidism were compared with 50 healthy sex- and age-matched controls using ambulatory blood pressure monitoring. RESULTS: Thyroid-stimulating hormone (TSH) levels were significantly higher in the subclinic hypothyroidism group, and there was no difference between free triiodothyronine (FT3) and free thyroxine (FT4) levels which could be predicted as a result of the study design. Levels of mean diastolic, daytime diastolic, nighttime diastolic and nighttime systolic blood pressure were significantly higher in the subclinic hypothyroidism group (p = 0.001 for mean, daytime and nighttime diastolic and p = 0.01 for nighttime systolic). Diastolic non-dipping occurred more frequently in the subclinic hypothyroidism group [subclinical hypothyroidism group 24 patients (49%), control group 13 patients (26%), p = 0.01]. On multivariate analysis, subclinical hypothyroidism was independently associated with diastolic non-dipping (95% confidence interval 1.162-8.053, odds ratio 1.182, p = 0.024). CONCLUSIONS: Our study found that both the frequency of diastolic non-dipping pattern and diastolic blood pressure increase with subclinical hypothyroidism. Therfore, it would appear that searching for non-dipping pattern can add valuable information for patients with subclinical hypothyroidism.

The relationship between left ventricular mass and insulin resistance in obese patients.

OBJECTIVE: In this study, we investigated the relationship between left ventricular mass and insulin resistance in obese patients. METHODS: A total of 90 subjects, 66 women, and 24 men, with an age range from 24 to 56 years, were enrolled in the study. Forty-nine patients were in the obesity group whose body mass index (BMI) was >29.9kg/m(2) and 41 subjects were in the control group with a BMI <25kg/m(2). All of them were normotensive, nondiabetic, and did not have any cardiovascular disease. They were not taking any medication. Weight, height, and waist circumference were measured and BMI was calculated. Plasma glucose, insulin, serum total, high-density lipoprotein (HDL) and low-density lipoprotein (LDL) cholesterol, and triglyceride levels were measured, and insulin resistance was calculated via homeostasis model of assessment-estimated insulin resistance (HOMA-IR). Subjects were examined by echocardiography and left ventricular mass (LVM) and index (LVMI) were calculated with Devereux formula. RESULTS: Insulin levels, HOMA-IR, LVM, and LVMI were significantly higher in obesity group (p<0.01). Fasting glucose, triglyceride, fasting insulin levels, and waist circumference did not correlate with LVMI. CONCLUSION: In conclusion, though findings of the present study suggest increased left ventricular hypertrophy (LVH) in obese subjects compared to controls, it appears that the increased LVM or LVH is not linked to BMI and insulin resistance in this study population.

Leptin as an important link between obesity and cardiovascular risk factors in men with acute myocardial infarction.

OBJECTIVE: The levels of leptin, a major regulator of lipid metabolism, may increase in obesity, and contribute to the development of metabolic syndrome. Leptin is produced by adipose tissue and is a peptide hormone, which has strong association with obesity, elevated cardiovascular risk, and morbidity. The present study was designed to evaluate the relationships between leptin levels, obesity, and cardiovascular risk factors in men with acute myocardial infarction. METHODS AND RESULTS: Twenty-four obese and twenty-three nonobese male patients, who had experienced their first myocardial infarction, were included in the study. Their leptin levels, biochemical parameters, and anthropometric measures were obtained. Mean leptin levels were significantly higher in the obese group compared to the nonobese group (2.53ng/mL versus 1.23ng/mL; p<0.01). Leptin levels correlated positively with anthropometric measurements, triglyceride, fasting glucose, C-reactive protein, and uric acid levels, and negatively with high-density lipoprotein cholesterol levels. CONCLUSION: Findings indicate high leptin levels to be positively correlated with obesity and diastolic blood pressure in male patients with myocardial infarction.

Interarm systolic blood pressure difference is associated with myocardial injury after noncardiac surgery.

BACKGROUND: Myocardial injury after non-cardiac surgery (MINS) is closely related to increased cardiovascular mortality. AIM: To evaluate the relationship between MINS and interarm systolic blood pressure difference (IASBPD), which has previously been shown to correlate with the frequency of cardiovascular events and arterial arteriosclerotic processes. METHODS: This observational, single-centre cohort study included 240 consecutive noncardiac surgery patients aged ≥ 45 years. Simultaneous blood pressure recordings were taken preoperatively and IASBPD was calculated. Patients' electrocardiography recordings and high sensitivity cardiac troponin T (hscTnT) levels were obtained for a period of three days postoperatively. RESULTS: Postoperatively, 27 (11.3%) patients were found to have MINS when hscTnT ≥ 14 ng/L was taken as a cut-off value. IASBPD > 10 mm Hg was found in 44 (18.3%) patients. When IASBPD was accepted to be a continuous variable, there was a higher IASBPD value in the MINS group (9.4 ± 5.0 vs. 4.5 ± 3.8, p < 0.000). When patients were grouped as those having IASBPD > 10 mm Hg and those not, exaggerate IASBPD was found to be more frequent in patients developing MINS (16 [59.3%] vs. 28 [13.1%], respectively, p < 0.000). Multiple logistic regression analysis found IASBPD > 10 mm Hg to be independently associated with the development of MINS (OR: 30.82; CI: 9.14-103.98; p < 0.000). Receiver operating char-acteristic curve analysis showed that the optimal IASBPD cut-off value for predicting MINS was 11.5 mm Hg, with a sensitivity of 61.0% and specificity of 89.1% (AUC = 0.79; 95% CI 0.71-0.87). CONCLUSIONS: Increased IASBPD is closely related to development of MINS. The preoperative measurement of blood pressure from both arms may be an important and easy to use clinical tool in determining cardiovascular risk.

Successful intracavitary tissue plasminogen activator treatment of gastrocnemius intramuscular hematoma in a patient following anticoagulant therapy with warfarin: case report.

Warfarin is an anticoagulant used in a variety of clinical indications and may rarely cause severe bleeding that can be life-threatening. Although intramuscular bleeding frequently occurs, secondary to trauma, it can be induced in cases with bleeding tendency. Hematoma is often treated with conventional methods. However, surgical decompression can also be applied. In this article, we report a case of gastrocnemius intramuscular hematoma, which was successfully treated with intracavitary tissue plasminogen activator that was recently used in the treatment of abdominal and pelvic abscess.

A new gap in the novel anticoagulants' era: undertreatment.

After long years of using warfarin for atrial fibrillation, new oral anticoagulants (NOACs) became available for decreasing the risk of ischemic stroke. Our aim was to observe the physicians prescribing patterns of NOACs. This prospective observational study included patients using NOACs applying consecutively to our outpatient clinic. Physical examination was performed, and patient history, electrocardiogram, transthoracic echocardiography, and biochemical results were collected. Bleeding and ischemic stroke risk scores (HAS-BLED and CHA2DS2-VASc scores) were calculated. We evaluated patients' characteristics, risk factors, concomitant drug usage, and physicians' choices. The study consisted of 174 patients using NOACs (dabigatran 113 patients, rivaroxaban 61 patients), with a mean age of 70.7 ± 8.8 years. The mean HAS-BLED score was 1.74 ± 0.9 and the mean CHA2DS2-VASc score was 3.7 ± 1.2. Fifty-three (30.4%) patients were prescribed low-dose NOAC according to the optimal dose, and 12 (6.8%) patients were prescribed high-dose NOAC according to the optimal dose. We compared optimal dose and undertreatment groups to find out if there was any predicting factor for physicians to use low dose of NOACs, but there was no significant difference between the two groups for age, sex, concomitant chronic disease, and CHA2DS2-VASc and HAS-BLED scores. NOACs were prescribed to patients mostly with high CHA2DS2-VASc score and low HAS-BLED score. Low-dose NOAC usage according to the optimal dose was frequent. Frequent coagulation monitoring and drug incompliance are big deficiencies at atrial fibrillation in use of warfarin. NOACs overcome these difficulties; however, physicians' hesitation to use NOACs with the optimal dosage may be another limitation in real-world practice.

The Association between Subclinical Hypothyroidism and Epicardial Adipose Tissue Thickness.

BACKGROUND AND OBJECTIVES: Subclinical hypothyroidism (SH) is considered to be a potential risk factor for cardiovascular disease. Epicardial adipose tissue (EAT) thickness is also closely related to cardiovascular disorders. The aim of this study was to evaluate whether SH is associated with higher EAT thickness. SUBJECTS AND METHODS: Fifty-one consecutive patients with SH and 51 healthy control subjects were prospectively enrolled into this trial. Thyroid hormone levels, lipid parameters, body mass index, waist and neck circumference, and EAT thickness measured by echocardiography were recorded in all subjects. RESULTS: Mean EAT thickness was increased in the SH group compared to the control group (6.7±1.4 mm vs. 4.7±1.2 mm, p<0.001). EAT thickness was shown to be correlated with thyroid stimulating hormone level (r=0.303, p=0.002). Multivariate logistic regression analysis revealed that EAT thickness was independently associated with SH {odds ratio (OR): 3.87, 95% confidence interval (CI): 1.92-7.78, p<0.001; OR: 3.80, 95% CI: 2.18-6.62, p<0.001}. CONCLUSION: Epicardial adipose tissue thickness is increased in patients with SH compared to control subjects, and this increase in EAT thickness may be associated with the potential cardiovascular adverse effects of SH.

Concurrent early-onset peripartum cardiomyopathy in a preeclampsia patient with acute pulmonary edema.

We herein report the case of a preeclampsia patient with comorbid peripartum cardiomyopathy (PPCMP). A 22-year-old woman in the 26th week of gestation was admitted with acute pulmonary edema. Hypertension and proteinuria were detected, and echocardiography showed an ejection fraction of 33%. It is remarkable that PPCMP particularly that associated with preeclampsia was observed in the early gestational period. In conclusion, while dyspnea and pretibial edema are often noted during normal pregnancies, the potential for PPCMP should be considered if these symptoms are excessive and/or comorbid paroxysmal nocturnal dyspnea and orthopnea are present, even in patients with preeclampsia.

Acute inferior myocardial infarction after electrical weapon exposure: case report and review of the literature.

The use of conducted electrical weapons (CEWs) by legal security forces and in civil society is rapidly increasing. While they are generally considered safe devices, and fatal complications are rare, it is possible to see a small number of complications. In the present case, we describe the detection of acute inferior myocardial infarction in a patient who experienced chest pain after being exposed to a CEW. In such cases, multiple factors should be considered, and the choice of treatment and follow-up should be decided accordingly.

Clinical staging in chronic heart failure associated with low vitamin D and elevated parathormone levels.

OBJECTIVE: Growing evidence in the literature suggests a relationship between heart failure and vitamin D-parathormone cascade. The aim of the present study was to investigate the association of the clinical stage of the heart failure with vitamin D-parathormone levels. METHODS AND RESULTS: Ninety consecutive patients, who were admitted to our clinic from December 2012 to May 2013, were included in the present study. The patients with heart failure were clinically classified into four stages (stage A through stage D). Vitamin D and parathormone levels were measured and echocardiographic recordings were obtained from each patient. The patients with heart failure had significantly lower vitamin D levels compared to the control group (14.5 ng/ml versus 38 ng/ml, P < 0.001). In the four subgroups of patients with heart failure, vitamin D levels significantly decreased (30 ng/ml, 25 ng/ml, 13.5 ng/ml, and 6 ng/ml in stages A, B, C, and D, respectively), and parathormone levels significantly increased (50 pq/ml, 44 pq/ml, 70 pq/ml, and 98.5 pg/ml, respectively) with progression in the heart failure from stage A to stage D (P < 0.001). The log10 EF (B = -2.39, 95% CI = -3.36-1.42, P < 0.001), log10 BNP (B = 0.405, 95% CI = 0.13-0.69, P = 0.005, log10 vitamin D (B = -0.75, 95% CI = -1.18-0.31, P = 0.001) were the independent predictors of heart failure stage in multivariate regression analysis. CONCLUSIONS: Vitamin D and parathormone levels were closely associated with the stage of heart failure. There was a significant decrease in vitamin D levels and a significant increase in serum parathormone levels with clinical deterioration in heart failure.

The relationship of acute myocardial infarction with or without ST-segment elevation and viscosity.

We compared hemorheological parameters in 42 male patients with acute myocardial infarction (AMI), with (n = 22) or without (n = 20) ST-segment elevation and in 20 controls. Plasma and blood viscosity (cP), plasma protein (g/dL) and fibrinogen (mg/dL) concentrations, red (10(6)/µL) and white (10(3)/µL) blood cell counts, hemoglobin concentration (g/dL), and hematocrit (%) were compared. Plasma viscosity was significantly higher in patients with AMI with (P = .012) and without (P = .046) ST-segment elevation than in controls. Patients with AMI with and without ST-segment elevation had significantly lower albumin (P = .002 and P = .009) and globulin (P = .001 and P = .007) concentrations, red blood cell counts (P = .0001 and P = .004), and hematocrit (P = .014 and P = .040) and significantly higher fibrinogen concentrations (P = .0001 and P = .001) than controls. These findings suggest that AMI in males is associated with increased plasma viscosity and fibrinogen concentrations and with decreased albumin and globulin concentrations, erythrocyte count, and hematocrit, regardless of ST-segment elevation.

The relationship between early atherosclerosis and endothelial dysfunction in type 1 diabetic patients as evidenced by measurement of carotid intima-media thickness and soluble CD146 levels: a cross sectional study.

BACKGROUND: Detection of early vascular changes prior to clinical manifestations of atherosclerosis, such as increased arterial carotid intima-media thickness (CIMT) and impaired endothelial function is of paramount importance for early identification of subjects at increased risk of accelerated atherosclerosis. The present study was designed to evaluate the relationship between early atherosclerosis and endothelial dysfunction in type 1 diabetic patients based on measurements of CIMT and soluble CD146 (sCD146) levels. METHODS: Thirty-seven patients with type 1 diabetes, 14 males (37.8%) and 23 females (62.2%), of mean (SD) age 26.2 (4.1) years admitted to the outpatient diabetes clinic at Okmeydani Training and Research Hospital, Istanbul, between January 2008 and December 2012, and 37 healthy controls, 16 males (43.2%) and 21 females (56.8%), of mean (SD) age 25.8 (3.1) years, selected from relatives of patients, were included. Anthropometric measures; fasting plasma glucose; and serum HbA1c, total cholesterol, HDL-cholesterol, LDL-cholesterol, triglyceride and creatinine concentrations were compared, as were CIMT and serum sCD146. RESULTS: Mean (SD) sCD146 levels were significantly higher in patients than in controls (314.6 (141.9) ng/ml vs. 207.8 (34.5) ng/ml, p = 0.001), but mean (SD) CIMT did not differ (0.5 (0.1) mm vs. 0.4 (0.1) mm). ROC curves for sCD146 significantly differed in differentiating type 1 diabetics from healthy controls (p = 0.0047) with a significantly higher percentage of patients than controls having sCD146 levels >260 ng/ml (21/37 (56.8%) vs. 2/37 (5.4%), p = 0.00011). CONCLUSION: Our findings emphasize that sCD146 levels may be a more sensitive marker than CIMT for earlier identification of type 1 diabetic patients at high risk for atherosclerosis.

Correlation between Left Ventricular Mass Index and Calcium Metabolism in Patients with Essential Hypertension.

OBJECTIVE: To determine the correlation between left ventricular mass index and calcium metabolism in patients with essential hypertension. STUDY DESIGN: Cross sectional case-control study. MATERIAL AND METHODS: Twenty-seven patients with essential hypertension and 20 healthy individuals were compared with respect to calciotropic hormones, left ventricular mass index (LVMI), and urinary and serum biochemical parameters. The correlations between parathormone, vitamin D, and calcitonin levels and LVMI and blood pressure elevation were determined. RESULTS: The parathormone level was significantly higher (p=0.006) and vitamin D level was significantly lower (p=0.01) in the patient group compared with the control group. However, the two groups were similar in terms of albumin-corrected calcium levels, which were within the normal range (p=0.988). The serum sodium (p=0.014) and urinary calcium (p=0.003) levels and LVMI (p<0.01) were also significantly higher in the patient group. No significant correlations were determined between ambulatory blood pressure and parathormone and vitamin D levels, but a significant correlation was found between LVMI and parathormone level (p=0.06) in hypertensive patients. CONCLUSION: Essential hypertension alters calcium metabolism, causing calciuresis by hypernatremia. Parathormone release increases to compensate for this, and leads to protein synthesis, which in turn provokes the development of myocardial hypertrophy.

Relationship between obstructive sleep apnea severity index and left ventricular function and volume.

BACKGROUND AND OBJECTIVES: Obstructive sleep apnea (OSA) causes increased cardiovascular morbidity and mortality, including systemic arterial hypertension, coronary heart disease, heart rhythm and conduction disorders, heart failure and stroke. In our study, we aimed to assess left ventricular mass and myocardial performance index (MPI) in OSA patients. DESIGN AND SETTING: A cross-sectional study conducted between May 2007 and August 2009 in a tertiary hospital in Istanbul, Turkey. PATIENTS AND METHODS: Forty subjects without any cardiac or pulmonary disease referred for evaluation of OSA had overnight polysomnography and echocardiography. According to the apnea-hypopnea index (AHI), subjects were classified into three groups; mild OSA (AHI: 5-14/h; n=7), moderate OSA (AHI: 15-29/h; n=13), and severe OSA (AHI: ;ge;30/h; n=20). The thickness of the interventricular septum (IVS) and left ventricular posterior wall (LVPW) were measured by M-mode along with left ventricular mass (LVM) and LVM index (LVMI). The left ventricular MPI was calculated as (isovolumic contraction time + isovolumic relaxation time)/aortic ejection time by Doppler echocardiography. RESULTS: No differences were observed in age or body mass index among the groups, but blood pressures were higher in severe OSA compared with moderate and mild OSA. In severe OSA, the thickness of the IVS (11.6 [1.7 mm]), LVPW (10.7 [1.7 mm]), LVM (260.9 [50.5 g]), and LVMI (121.9 [21.1g/m2]) were higher than in moderate OSA (9.4 [1.3 mm]; 9.9 [1.6]; 196.4 [35.2]; 94.7 [13.2 g/m2], respectively) and mild OSA (9.8 [2.4 mm], 8.9 [2.0 mm], 187.6 [66.2 g], 95.8 [28.6 g/m2], respectively). In severe OSA, MPI (0.8 [0.2]) was significantly higher than in mild OSA (0.5 [P<.01]) but not significantly higher than moderate OSA (0.8 [0.1]). CONCLUSIONS: OSA patients have demonstrable cardiac abnormalities that worsen with the severity of apnea. The MPI may have utility in subsequent OSA studies, possibly as a surrogate outcome measure.

Evaluation of the relationship between insulin resistance and plasma tumor necrosis factor-alpha, interleukin-6 and C-reactive protein levels in obese women.

OBJECTIVE: To investigate the relationship between insulin resistance and tumor necrosis (TNF)-alpha, interleukin (IL)-6, C-reactive protein (CRP) in obese women. BACKGROUND: Obesity and type 2 diabetes are associated with insulin resistance, the mechanisms of which remain poorly understood. MATERIALS AND METHODS: Forty obese (35.8 +/- 9.6 years) and 20 non-obese women (31.1 +/- 7.7) were recruited between June 2002 and February 2003 at the Okmeydaný Training and Research Hospital, Istanbul, Turkey. The obese group was equally divided into two according ?to their WHR (> 0.8 and 0.8). Subjects with blood pressure values higher than 140/90 mmHg, pathological findings on standard 12-lead EC3 and leukocytosis and glucose levels > 100 mg/dl were excluded. RESULTS: Plasma insulin (p < 0.0001) and fasting glucose levels (p<0.0001), and HOMA values (p < 0.0001) in the obese group were higher than in the controls. Serum triglyceride and VLDL levels were higher in the obese group (p < 0.0001 in both), whereas HDL cholesterol levels were higher in the lean control group (p < 0.0001). However, no difference was observed between two groups in terms of total cholesterol and LDL-cholesterol levels. The serum levels of both TNF-alpha, IL-6 and CRP were found elevated in the obese group (p < 0.05, p < 0.05, p < 0.01, respectively). In the subgroup analysis, only the HOMA values and TNF-alpha levels were found higher in the android obese group (p < 0.05 and p < 0.0001, respectively). CONCLUSION: Insulin resistance seems to be one of the major causes of obesity-related complications due to increased secretion of TNF-alpha, IL-6 and CRP together with android obesity (Tab. 5, Ref. 33).

Acute myocardial infarction in a patient with hemophilia A and factor V Leiden mutation.

Factor VIII:C, epsilon amino-caproic acid or tranexamic acid are prophylactic agents used in preventing hemorrhage pre-operatively in patients with hemophilia A. Although hemophilia A seems to be a factor that avoids the development of acute myocardial infarction (AMI) as it tends to be associated with increased bleeding, it should be kept in mind that prothrombotic agents used pre-operatively for prophylaxis may increase the risk for AMI in the presence of the factor V Leiden mutation. In this report, we discuss the development of AMI following the use of recombinant factor VIII and tranexamic acid for prophylaxis in a patient with known hemophilia before a tooth extraction in conjunction with the relevant literature.
