Association of red blood cell distribution width to albumin ratio with prognosis in stroke patients.

Aim: The authors investigated the association of red blood cell distribution width to albumin ratio (RAR) with prognosis and severity in acute ischemic stroke (AIS). Methods: One hundred twenty-seven patients with AIS were prospectively analyzed. The NIH Stroke Scale was used to determine stroke severity. RAR was compared between severe and nonsevere patients. Results: RAR was significantly higher in severe compared with nonsevere patients (p < 0.001). According to receiver operating characteristic analysis, RAR alone predicted mortality better than red blood cell distribution width and albumin (area under the curve: 0.933, 0.911, 0.870, respectively). Additionally, RAR was significantly correlated with NIH Stroke Scale score (p < 0.001). Conclusion: High RAR measured at presentation is a feasible index for prognosis and severity stratification in AIS.

Echocardiographic and hemodynamic changes in patients with high-grade varicocele.

Varicocele is abnormal tortuosity and dilatation of the pampiniform plexus veins within the spermatic cord. Varicocele is associated with testicular atrophy, hypogonadism, impaired semen analysis values, or decreased testosterone production. Varicocele is a progressive disease and should be treated because it may be a systemic disease that can be associated with cardiovascular abnormalities. We hypothesize in this study that cardiovascular and hemodynamic pathologies may occur in varicocele patients. In this prospective, multicentric, multidisciplinary study, patients diagnosed with high-grade left varicocele in the urology clinic underwent semen analysis, total testosterone determination, and scrotal Doppler ultrasonography. In addition, blood pressure measurement and echocardiographic evaluation were performed by blinded cardiologists in both the varicocele patients and the healthy control group. The study was carried out with 103 varicocele patients and 133 healthy individuals who formed the control group. Diastolic blood pressure (P = 0.016), left ventricular end diastolic (P < 0.001) and systolic diameter (P < 0.001), ejection fraction (P < 0.001), pulmonary arterial pressure (P < 0.001), and aortic distensibility (P < 0.001) values were significantly higher in varicocele patients compared with controls; interventricular septum wall thickness (P = 0.022), aortic systolic (P < 0.001) and diastolic diameter (P < 0.001), aortic systolic (P < 0.001) and diastolic diameter index (P < 0.001), and aortic stiffness index (P < 0.001) values were significantly lower in varicocele patients. The mean aortic distensibility of non-normozoospermic group was lower than that of normozoospermic group (P = 0.041). There was no statistically significant relationship between thickest vein diameter in spermatic cord and cardiological parameters. This study showed that symptomatic patients with high-grade varicocele had a higher risk of cardiovascular and hemodynamic disease. We recommend that men with high-grade symptomatic varicocele with impaired semen analysis undergo cardiovascular and hemodynamic evaluation regardless of their spermatic vein diameter.

Relationship between Retinal Nerve Fiber Layer Thickness and Aortic Distensibility in Peripheral Arterial Disease Patients.

AIM AND OBJECTIVE: To evaluate the relationship between aortic distensibility (AD) and aortic stiffness B index (ASBI) with retinal nerve fiber layer (RNFL) thickness measured with HD-OCT in peripheral arterial disease (PAD) patients. MATERIALS AND METHODS: Twenty-six PAD patients and 22 age-matched healthy control were enrolled. Subjects with PAD were classified into two groups. Patients with diabetes (DM) or hypertension (HT) comprised group I (n = 18) and without DM or HT comprised group II (n = 8). Color Doppler imaging was performed on all patients and PAD was diagnosed by using the ankle-brachial index (ABI). Retinal nerve fiber layer thickness values between control and PAD patients and correlations between RNFL thickness and aortic stiffness parameters (AD and ASBI) were evaluated. RESULTS: The inferior-nasal and inferior-temporal quadrant were the thickest in healthy subjects and the PAD group. Retinal nerve fiber layer thickness significantly decreased in superior-nasal, temporal, inferior-nasal quadrants in group I than healthy subjects (p < 0.001, p = 0.005, p < 0.001). Temporal and inferior-nasal quadrant thicknesses were statistically significantly thinner in group II than controls (p = 0.02, p < 0.001). The nasal RNFL quadrant was significantly thinner in group I than group II (p = 0.014). The correlation between RNFL thickness and aortic elasticity parameters in each group was not found to be significant. CONCLUSION AND CLINICAL SIGNIFICANCE: Isolated PAD without DM or HT may lead to localized RNFL loss in temporal and inferior-nasal quadrants. Aortic elasticity parameters did not seem to be correlated with RNFL thickness in PAD. HOW TO CITE THIS ARTICLE: Kumova D, Aktas Z, Eyiol A, et al.

Relationship of serum HLA-B alleles and TNF-α with rheumatic heart disease

Background/aim: Acute rheumatic fever and rheumatic heart disease are major causes of morbidity and mortality in developing countries. Genetic studies have determined that the immune response in rheumatic heart disease is genetically controlled and that there is a close relationship between the gene of concern and the class II human leukocyte antigen (HLA) gene. The aim of this study was to evaluate the relationship of serum HLA-B alleles and tumor necrosis factor alpha (TNF-α) with rheumatic heart disease. Materials and methods: A total of 50 consecutive patients with rheumatic heart disease and 50 controls were enrolled in the study. HLA alleles were analyzed using sequence-specific primer-polymerase chain reaction and nucleotide sequencing. Results: The HLA-B35 allele was significantly more common in patients with rheumatic heart disease than the control group (P = 0.043). The HLA-B44 allele was significantly more common in control patients than in patients with rheumatic heart disease (P = 0.014). There was a significant inverse correlation between high-sensitivity C-reactive protein and mitral valve area (P = 0.001). There was no correlation between TNF-α levels and mitral valve area (P = 0.066). Conclusion: Our findings confirmed the association between HLA-B alleles and rheumatic heart disease.

Association of rs10757274 and rs2383206 Polymorphisms on 9p21 locus with Coronary Artery Disease in Turkish Population.

BACKGROUND AND OBJECTIVES: Genetic predisposition is an important risk factor for coronary artery disease (CAD). In this study, we aimed to evaluate the impact of rs10757274 and rs2383206 polymorphisms in chromosome 9p21 on presence and severity of CAD in a Turkish population. SUBJECTS AND METHODS: A total of 646 patients who underwent coronary angiography were included in this study. Coronary vessel score and Gensini score were calculated to assess the angiographic severity of CAD. Alleles of AA, AG, and GG were determined for rs10757274 (polymorphism-1) and rs2383206 (polymorphism-2) polymorphisms located in chromosome 9p21 from the blood samples. RESULTS: There was a significant difference between the alleles in polymorphism-1 in the presence of coronary artery disease (38.9% in AA, 48.0% in GG and 56.4% in AG, p=0.017). However, there was no difference between the alleles in polymorphism-2. According to vessel scores, there was a significant difference between the alleles in polymorphism-1 (AA 0.71±1.04, GG 0.88±1.07, AG 1.06±1.12, p=0.018). In polymorphism-2, vessel scores did not show a difference between the alleles. In polymorphism-1, there was a significant difference in Gensini score (p=0.041). Gensini scores did not differ between the alleles in polymorphism-2 (p>0.05 for all). In multivariate analyses, none of the alleles was an independent factor for presence of CAD. CONCLUSION: The presence of rs10757274 polymorphism including AG allele in chromosome 9p21 was related to CAD. However, this relationship was not independent of other cardiovascular risk factors.

[The relationship between mitral annular calcification and red cell distribution width: a cross-sectional study]. / Mitral anülüs kalsifikasyonu ile kirmizi kan hücresi dagilim genisligi iliskisi: Kesitsel bir çalisma.

OBJECTIVE: Mitral annular calcification (MAC) and atherosclerosis are similar in regard to risk factors and pathogenesis. Increased red blood cell distribution width (RDW) has been shown to be associated with atherosclerotic diseases. However, no data evaluating the association of MAC with RDW has been available. The aim of this cross-sectional study was to investigate the relationship between MAC and RDW among patients with various cardiovascular risk factors. METHODS: A total of 623 patients (MAC-positive group: n=413; control group: n=210) admitted to our cardiology outpatient clinics were enrolled between March and November 2014. Demographic, clinical, and laboratory parameters of all participants were recorded. RDW was analyzed from complete blood samples of study participants. RESULTS: Patients in MAC-positive group showed older age and higher rate of hypertension. Mean RDW value was significantly higher in MAC-positive group, compared to control group (15.3±1.4% vs. 13.9±1.4%, p<0.001). In Pearson correlation analysis, statistically significant and positive correlation was determined between neutrophil-lymphocyte ratio and RDW (r=0.284, p<0.001). In multivariate logistic regression analysis, age (OR: 1.041, p<0.001), hypertension (OR: 1.540, p=0.039), and RDW (OR: 5.351, p<0.001) were determined as independent predictors of MAC. CONCLUSION: RDW levels were significantly increased in patients with MAC, and RDW was determined as an independent predictor for presence of MAC. Therefore, increased RDW can be used as a marker of continuing inflammatory process in MAC patients.

Comparison of three diuretic treatment strategies for patients with acute decompensated heart failure.

BACKGROUND: There are few prospective data available for establishing a standard diuretic administration regimen for patients with acute decompensated heart failure (ADHF). We aimed to assess the safety and efficacy of three regimens of furosemide administration in patients with ADHF with regard to diuresis, renal functions, and in-hospital outcomes. METHODS: A total of 43 patients who presented with ADHF were randomized into three groups: (a) continuous infusion (cIV) of 160 mg furosemide for 16 h/day (n = 15); (b) bolus injections (bI) of 80 mg furosemide twice a day (n = 14); (c) and administration of 160 mg furosemide plus hypertonic saline solution (HSS) as an infusion for 30 min once a day (n = 14). All regimens were continued for 48 h. Study endpoints were negative fluid balance assessed by loss of body weight, change in the serum creatinine (baseline to 48 h and baseline to compensated state), and length of hospitalization. RESULTS: There was no significant difference in the mean change in serum creatinine level at the end of 48 h between groups (p = 0.08). There was also no significant difference among groups regarding loss of body weight (p = 0.66). A significantly shorter hospitalization was observed in patients treated with HSS compared with the other groups (cIV group 6.6 ± 3.4 days vs. bI group 7.9 ± 4.1 days vs. HSS group 3.7 ± 1.3 days; p < 0.01). CONCLUSION: All three furosemide regimens have similar renal safety and efficacy measures. However, administration of furosemide plus HSS may be the preferred diuretic strategy because of its shorter hospital stay.

The Assessment of Atrial Electromechanical Delay in Patients With Acromegaly.

BACKGROUND: We aimed to evaluate whether atrial electromechanical delay (AEMD) measured by tissue Doppler imaging (TDI), which is an indicator for structural and electrical remodelling of the atria, is prolonged in patients with active or inactive acromegaly, or both, compared with a control group. METHODS: A total of 34 patients with acromegaly (18 active/16 inactive) and 35 patients as a control group were enrolled. Both intra- and inter-AEMD were calculated by TDI. The correlation between clinical variables and AEMD were analyzed. RESULTS: Both inter-AEMD and right and left intra-AEMD were prolonged in patients with acromegaly compared with the control group (P < 0.001, P < 0.001, and P = 0.004, respectively). Also, patients with active acromegaly showed higher inter-AEMD and right intra-AEMD compared with patients with inactive acromegaly (P < 0.05). There was no significant difference in left intra-AEMD between patients with active acromegaly and those with inactive acromegaly (P = 0.977). The growth hormone and insulin-like growth factor (IGF-1) levels positively correlated with inter-AEMD (r = 0.577; P < 0.001; r = 0.614; P < 0.001, respectively). Additionally, we found that inter-AEMD was significantly and positively correlated with relationship between maximal values of passive mitral inflow (E, PW-Doppler) and lateral early diastolic mitral annular velocities (e', TDI) (r = 0.316; P = 0.008). Only the serum IGF-1 level was independently associated with inter-AEMD in multivariate linear regression analysis (ß = 0.500; P = 0.011). CONCLUSIONS: Our study findings showed that both inter- and intra-AEMD are prolonged in patients with acromegaly. Also, AEMD was observed to be more prolonged in patients with active acromegaly than in those with inactive acromegaly. IGF-1 was an independent predictor of inter- AEMD in patients with acromegaly. Being a noninvasive, inexpensive, and simple technique, AEMD may be used as an indicator for atrial electrical and structural remodelling in patients with acromegaly.

Association of neutrophil-lymphocyte ratio with impaired aortic elasticity in newly diagnosed and never-treated hypertensive patients.

OBJECTIVES: The aim of our study was to investigate the relationship between neutrophil-to-lymphocyte ratio (NLR) and aortic elasticity in patients with newly diagnosed essential hypertension (HT). DESIGN: A total of 101 patients with newly diagnosed and untreated essential HT and 54 healthy control patients were enrolled. Aortic stiffness (ß) index, aortic strain and aortic distensibility (AoD) were measured with formulas by using transthoracic echocardiography and office blood pressure obtained by sphygmomanometer data. NLR was calculated using complete blood count. RESULTS: Patients with HT had significantly higher NLR compared with the healthy control group (2.49±0.77 vs. 1.80±0.65, P<0.001). In addition, there were significant differences between the HT and healthy control groups in ß index (12.7±7.35 vs. 6.97±3.3, P<0.001) and AoD (3.0±1.54 vs. 4.85±1.35, P<0.001). There was also a statistically significant correlation between NLR and ß index (r=0.727, P<0.001) and AoD (r=-0.606, P<0.001) parameters in hypertensive patients. CONCLUSION: Our results showed that in patients with newly diagnosed and untreated essential HT, increased NLR has been significantly linked to impaired aortic elastic properties.
