    [Show abstract] [Hide abstract] ABSTRACT: Introduction: Chronic inflammation is a major risk factor in the pathogenesis of cardiovascular disease in end-stage renal disease (ESRD) patients. Epicardial adipose tissue (EAT) is the true visceral fat depot of the heart. The relationship between coronary artery disease and EAT was shown in healthy subjects and ESRD patients. In the present study we aimed to investigate the relationship between EAT and inflammation parameters including neutrophil-to-lymphocyte ratio (NLR) in hemodialysis (HD) patients. Material and methods: Forty-three HD patients (25 females, 18 males; mean age: 64.1 ±11.9 years) receiving HD and 30 healthy subjects (15 females, 15 males; mean age: 59.1 ±10.8 years) were enrolled in the study. Epicardial adipose tissue measurements were performed by echocardiography. Results: Neutrophil-to-lymphocyte ratio levels were significantly higher in HD patients than in the healthy control group. Hemodialysis patients were separated into two groups according to their median value of NLR (group 1, NLR < 3.07 (n = 21) and group 2, NLR ≥ 3.07 (n = 22)). Group 2 patients had significantly higher EAT, C-reactive protein and ferritin levels, while albumin levels were significantly lower in this group. In the bivariate correlation analysis, EAT was positively correlated with NLR (r = 0.600, p < 0.001) and ferritin (r = 0.485, p = 0.001) levels. Conclusions: Neutrophil-to-lymphocyte ratio was found to be an independent predictor of EAT in HD patients (odds ratio = 3.178; p = 0.008). We concluded that this relationship might be attributed to increased inflammation in uremic patients.

    [Show abstract] [Hide abstract] ABSTRACT: Introduction Association of vitamin D, inflammation and endothelial dysfunction, beside the classic bone metabolism disorders, may explain the pathogenesis of numerous diseases associated with vitamin D deficiency. While large numbers of reports support the relationship of vitamin D with inflammation, several reports fail to confirm this relationship. Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are novel and inexpensive markers of inflammation that can be studied in all centers. The goal of this study was to investigate the association between 25-hydroxy vitamin D (25(OH)D) and inflammation with the novel inflammatory markers NLR and PLR. Material and methods This study was performed retrospectively. Results of the simultaneously performed 25(OH)D, parathyroid hormone, albumin, calcium, phosphorus, alkaline phosphatase and creatinine level measurements and complete blood count were recorded. The data of 4120 patients were included in the study. Results Between vitamin D deficient and non-deficient groups there were significant differences in PLR (p < 0.001) and NLR (p = 0.001). Vitamin D had a significant negative correlation with PLR (p < 0.001) and NLR (p < 0.001). Multiple regression analysis indicated that 25(OH)D was independently and negatively correlated with PLR (OR = 0.994, 95% CI 0.991–0.998, p = 0.02). Conclusions Platelet-to-lymphocyte ratio and NLR were significantly associated with 25(OH)D levels, and PLR was found to be an independent predictor of 25(OH)D levels. Our study revealed an inverse association of vitamin D levels and inflammation with these inexpensive and universally available markers.

    [Show abstract] [Hide abstract] ABSTRACT: Intestinal mucositis is one of the major problems in the patients receiving cancer treatment. Nimesulide is a drug with antioxidant, antiinflammatory and antiulcer features. We aimed to investigate the effect of nimesulide on the small intestine mucositis induced by methotrexate (MTX) in rats. Experimental animals were divided into the control group, MTX group (MTXG) and nimesulide+MTX administered group (NMTXG) with eight rats per group. The control and MTXG groups were given distilled water by gavage and the NMTXG was given nimesulide 100 mg/kg orally. After one hour, the NMTXG and MTXG rat groups were administered oral MTX 5 mg/kg. This procedure was repeated once a day for 15 days and the rats were sacrificed. The duodenum and jejunum of each rat was removed for the assessment of biochemical markers and histopathological evaluation. Malondialdehyde (MDA) and myeloperoxidase (MPO) levels were significantly higher in the duodenal and jejunal tissues of the animals which received MTX, compared to the control and NMTXG (P<0.001). Also, the levels of total glutathione (tGSH), glutathione reductase (GSHRd), glutathione peroxidase (GSHPx), catalase (CAT) and superoxide dismutase (SOD) were significantly lower in the MTXG (P<0.001) compared to other groups. MTX led to villus and crypt epithelial damage and inflammation containing marked PMNL and eosinophils in the intestinal tissues histopathologically. Whereas, there was only mild irregularities in the villus structures of the NMTXG. Nimesulide protected the small intestines against damage by MTX. Intestinal mucositis caused by MTX may be preventable by co-administered nimesulide.

    [Show abstract] [Hide abstract] ABSTRACT: Objective . Effects of high frequency chest wall oscillation technique were investigated on intubated ICU patients. Background . Thirty intubated patients were included in the study. The control group ( n = 15 ) received routine pulmonary rehabilitation technique. In addition to the pulmonary rehabilitation technique, the study group ( n = 15 ) was given high frequency chest wall oscillation (HFCWO). APACHE II, dry sputum weight, lung collapse index, and blood gas values were measured at 24th, 48th, and 72nd hours and endotracheal aspirate culture was studied at initial and 72nd hour. The days of ventilation and days in ICU were evaluated. Results . There is no significant difference between APACHE II scores of groups. The dry sputum weights increased in the study group at 72nd hour ( p = 0 . 001 ). The lung collapse index decreased in study group at 48th ( p = 0 . 003 ) and 72nd hours ( p < 0 . 001 ). The PO 2 levels increased in the study group at 72nd hour ( p = 0 . 015 ). The culture positivity at 72nd hour was decreased to 20%. The days of ventilation and staying in ICU did not differ between the groups. Conclusions . Although HFCWO is very expensive equipment, combined technique may prevent the development of lung atelectasis or hospital-acquired pneumonia more than routine pulmonary rehabilitation. It does not change intubated period and length of stay in ICU. However, more further controlled clinical studies are needed to use it in ICU.

    [Show abstract] [Hide abstract] ABSTRACT: To determine the seroprevalence and risk factors associated with Crimean-Congo hemorrhagic fever virus (CCHFV) in residents of Erzincan, Turkey. Although CCHFV is endemic in Erzincan, this is the first study to evaluate its seroprevalence in this region. This study included a total of 372 subjects, 174 of whom had been exposed to or bitten by ticks, 145 of whom worked with livestock, and 53 of whom resided in the city and did not have exposure to livestock. Data on CCHFV IgG and IgM antibodies were extracted from serum samples collected from all subjects using an ELISA. All samples were tested for CCHFV IgG and CCHFV IgM. Only IgM-positive samples were processed for detection of viral RNA through RT-PCR. Using seropositive cases only, we performed spatial analyses to evaluate correlations between seroprevalence and geographic location (i.e., proximity to rivers, altitude, and slope angle of land). In this study, 14.0% (52/322) of the total subjects were positive for CCHFV IgG. Seven of the individuals were positive both for CCHFV IgG and CCHFV IgM. Of these seven, only one sample tested positive for CCHFV RNA. Individuals who worked with livestock in the rural areas and had a history of tick exposure were statistically more likely to test positive for CCHFV IgG than individuals from the city and not exposed to ticks (p < 0.05). Seroprevalence was affected by geographic characteristics, including distance to rivers, altitude, and slope angle of land. We observed a high seroprevalence of CCHFV in Erzincan, which is similar to that observed in other endemic regions of Turkey. CCHFV seroprevalence rates are found to be quite high in the people who live in the sloping fields at certain heights and where there are a lot of rivers and streams.

    [Show abstract] [Hide abstract] ABSTRACT: Objective: To assess the impact of resveratrol on oxidative stress induced by methotrexate in rat ileum tissue. Materials and methods: Twenty four rats were divided into 4 groups, 6 in each group. Each rat was given the following orally every day for 30 days; Group 1 (MTXG): methotrexate (MTX)(5 mg/kg); Group 2 (RMTXG): MTX(5 mg/kg) plus resveratrol (RST)(25mg/kg/day); Group 3 (RSTG): RST(25mg/kg/day)alone ; and Group 4 (control) distilled water. After sacrifing the rat, , the ileums were removed for the assessment of malondialdehyde (MDA), total glutathione (tGSH) and glutathione peroxidase (GSH-Px). Gene expression analyses for interleukin-1ß (IL-1ß), tumor necrosis factor-α (TNF-α) and myeloperoxidase (MPO) were also performed. Haematoxylin-eosin stained paraffin embedded sections of the ileum were analyzed under light microscope and the findings were recorded. Statistical analyses of the data were done using the one-way ANOVA. Results: Administration of MTX in group 1 yielded higher level of MDA(8.33±2.5, p < 0.001) and lower levels of tGSH(0.97±0.29) and GSH-Px(5.22±0.35, p < 0.001) compared to other groups. The MTX also increased IL-1ß(40.33±5.43), TNF-α(6.08±0.59) and MPO gene expression(9±1.41) in group 1 compared to controls(11.33±2.07, 2.15±0.33 and 3.43±0.48, p < 0.001). The impact of RST on IL-1ß, TNF-α and MPO gene expression induced by MTX were observed as a reversal of these findings(p < 0.05). Severe inflammation, damage to the villus epithelium and crypt necrosis were observed histopathologically in MTXG group, whereas only a mild inflammation was seen in the RMTXG group. Conclusion: In this study the ileal damage caused by MTX was inhibited by using RST.

  • [Show abstract] [Hide abstract] ABSTRACT: In recent years, there has been renewed interest in hematological parameters as predictors of endothelial dysfunction and inflammation. The aim of our study is to evaluate the relationship between HbA1c and hematological indices, and to evaluate the relationship between these parameters and microvascular complications of diabetes. Three hundred and seven diabetic patients (124 male, 183 female; mean age 50.8±8.5), and 187 controls (76 male, 111 female; mean age 51.1±10.1) were included in the study. In the diabetic group, mean platelet volume (MPV), plateletcrit (PCT), platelet distribution width (PDW), white blood cell count (WBC), platelet count, platelet to lymphocyte ratio (PLR) and neutrophil to lymphocyte ratio (NLR) were significantly higher than the control group (P<0.05). Diabetic patients were divided into two group according to their HbA1c levels (Group 1; HbA1c <7 (n=82) and group 2; HbA1c ≥7 (n=225)). Mean platelet volume, PCT and PDW levels were significantly increased in group 2. Mean platelet volume was significantly increased in diabetic patients with retinopathy compared to those without retinopathy (P=0.006). The neutrophil to lymphocyte ratio and PLR levels were significantly higher in patients with nephropathy (P=0.004, P=0.004 respectively). There was statistically significant difference of lymphocyte count between patients with and without neuropathy. In correlation analysis, positive correlation between HbA1c and PCT (rs=0.192, P<0.001), HbA1c and PDW (rs=0.305, P<0.001), HbA1c and MPV (rs=0.352, P<0.001) were determined. In binary logistic regression analysis; WBC, PDW and PLR levels were found to be independently associated with diagnosis of diabetes while WBC, MPV, PLR and NLR levels were found to be independently associated with impaired glucose regulation. This study demonstrates that altered hematological indices are closely associated with HbA1c levels in individuals with and without diabetes and some of these parameters are associated with diabetic microvascular complications. These associations may be explained by connection between these easy accessible and inexpensive hematological indices and inflammation, tendency to coagulation and thrombosis in patients with diabetes.

    [Show abstract] [Hide abstract] ABSTRACT: Backround: Surgical operations are alternative treatments in persons with Obstructive Sleep Apnea Syndrome who cannot tolerate continuous positive airway pressure therapy. Drug-Induced Sleep Endoscopy is a method with which somnolence is pharmacologically induced and collapse is evaluated through nasal endoscopy in patients with Obstructive Sleep Apnea Syndrome. We aimed to evaluate efficiency of dexmedetomidine or propofol used for sedation in patients undergoing drug-induced sleep endoscopy. A total of 40 patients aged between 18 and 65 years old in the ASA STATUS I-II group were included in the study. After premedicatıon wıth midazolam 0.05 mg/kg intravenously, patients were randomly divided into two groups and administered intravenous (iv) propofol with the loading dose of 0.7 mg/kg for 10 minutes, followed 0.5 mg/kg/h infusion (Group P); or dexmedetomidine with the loading dose of 1 mcg/kg for 10 minutes, followed by 0.3 mcg/kg/h infusion (Group D). Haemodynamic and respiratuary parameters, Bispectral index score, Ramsey sedation score, time to achieve sufficient sedation, surgeon's and patients' satisfaction, postoperative Aldrete score and side effects were recorded. Time to achieve sufficient sedation, Bispectral index scores at 5, 10 and 15th. minutes intraoperatively, first Aldrete score in the recovery room, SpO2 values and respiratory rates all over the surgical procedure and in the recovery room were found lower in Group P (P<0.05). Bispectral index scores, mean arterial pressure and heart rate in the recovery room were significantly lower in Group D (P<0.05). Dexmedetomidine may be preferred as a safer agent with respecting to respiratory function compared with propofol in obstructive sleep apnea patients who known to be susceptible to hypoxia and hypercarbia.

    [Show abstract] [Hide abstract] ABSTRACT: The aim of our study was to evaluate the total atrial conduction time and its relationship to subclinical atherosclerosis, inflammation and echocardiographic parameters in patients with type 2 diabetes mellitus. A total of 132 patients with type 2 diabetes mellitus (mean age 54.5±9.6 years; 57.6% male) and 80 age- and gender-matched controls were evaluated. The total atrial conduction time was measured by tissue-Doppler imaging and the carotid intima-media thickness was measured by B-mode ultrasonography. The total atrial conduction time was significantly longer in the patients with type 2 diabetes mellitus than in the control group (131.7±23.6 vs. 113.1±21.3, p<0.001). The patients with type 2 diabetes mellitus had significantly increased carotid intima-media thicknesses, neutrophil to lymphocyte ratios and high-sensitivity C-reactive protein levels than those of the controls. The total atrial conduction time was positively correlated with the high-sensitivity C-reactive protein level, neutrophil to lymphocyte ratio, carotid intima-media thickness and left atrial volume index and negatively correlated with the early diastolic velocity (Em), Em/late diastolic velocity (Am) ratio and global peak left atrial longitudinal strain. A multiple logistic regression analysis demonstrated that the neutrophil to lymphocyte ratio, carotid intima-media thickness and global peak left atrial longitudinal strain were independent predictors of the total atrial conduction time. We suggest that subclinical atherosclerosis and inflammation may represent a mechanism related to prolonged total atrial conduction time and that prolonged total atrial conduction time and impaired left atrial myocardial deformation may be represent early subclinical cardiac involvement in patients with type 2 diabetes mellitus.

    [Show abstract] [Hide abstract] ABSTRACT: In this study, the in vivo effects of two proton pump inhibitors - rabeprazole and esomeprazole - on enzyme activities of red blood cell enzymes, including glucose 6-phosphate dehydrogenase, 6-phosphogluconate dehydrogenase, and glutathione reductase, were investigated. In the first part of our study, activities of these enzymes in the group of patients diagnosed with reflux were compared with the enzyme activities of the voluntary individual group with no health problems (control group). No significant difference was found between the groups for glucose 6-phosphate dehydrogenase and 6-phosphogluconate dehydrogenase enzymes (p > 0.05). However, the level of glutathione reductase increased in reflux patients, as compared to healthy controls (p < 0.05). Additionally, the enzyme activities of the patient group members who used esomeprazole or rabeprazole for a 1-month-treatment were compared with the values obtained when these patients initially consulted our clinic. No significant difference was found between the groups for the three enzymes (p>0.05).

    [Show abstract] [Hide abstract] ABSTRACT: The associations of serum uric acid (UA), atherogenic index of plasma (AIP) and albuminuria with cardiovascular disease have been shown. Several studies focused on association of serum UA and dyslipidemia, serum UA and renal impairment, dyslipidemia and renal impairment. However, to date, in literature, there have been no studies demonstrating the relationship between these parameters in diabetic patients together. We aimed to investigate the association between serum UA, albuminuria and AIP in diabetic patients. This was a retrospective study involving data of 645 diabetic patients. The patients were separated into groups according to their serum uric acid and AIP levels. The quantitative urine albumin/creatinine ratio in morning spot urine samples were used for standard albuminuria determination. Serum uric acid levels under 6 mg/dL were considered as normal. AIP was calculated as the logarithmically transformed ratio of triglyceride to high density lipoprotein cholesterol. AIP and albuminuria levels were high in high serum UA group compared to normal UA group. Uric acid and albuminuria tended to increase with increasing AIP. Correlation analysis showed that albuminuria, AIP and UA were significantly correlated with each other. Additionally, in binary logistic regression analysis, AIP was found to be independently associated with high UA levels. Present study reveals that serum UA, AIP and albuminuria are closely related. Physicians should be aware that patients with concomitant hyperuricemia, albuminuria and high AIP are at increased risk of developing cardiovascular disease. Our study confirms that there is a need for larger prospective studies to determine the mechanisms underlying the association of serum UA, AIP and albuminuria.

    [Show abstract] [Hide abstract] ABSTRACT: Background: The relationship between diabetic nephropathy, visceral adipose tissue (VAT), and inflammation has been shown. The neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are simple, inexpensive, and useful markers to determine inflammation. However, to date, in the literature, there have been no studies demonstrating the relationship between epicardial adipose tissue (EAT), inflammation, and albuminuria. Aims: We aimed to investigate the association between diabetic nephropathy, NLR, and PLR as inflammatory markers and EAT thickness. Methods: This was a cross-sectional study involving 200 diabetic patients. The patients were separated into three groups according to their albuminuria levels. The NLR and PLR were calculated from a complete blood count. EAT was measured by transthoracic echocardiography. The estimated glomerular filtration rate (eGFR) was calculated by the modification of diet in renal disease (MDRD) equation. Results: Disease duration, EAT, creatinine, NLR, PLR, absolute neutrophil, lymphocyte, and platelet count tended to increase with increasing albuminuria while the eGFR decreased. When patients were separated into two groups according to NLR and PLR medians, albuminuria levels increased with an increase of the NLR (p = 0.003) and PLR (p = 0.009). A correlation analysis showed that albuminuria was significantly correlated with EAT, disease duration, creatinine, eGFR, PLR, and NLR levels. Additionally, in a binary logistic regression analysis, EAT, NLR, and PLR were found to be independently associated with albuminuria. Conclusions: Determining various inflammatory cytokines and measuring abdominal VAT in diabetic patients is complex and expensive. Simply measuring EAT and calculating NLR and PLR can predict inflammation and albuminuria in patients with diabetes.

    [Show abstract] [Hide abstract] ABSTRACT: Epicardial adipose tissue (EAT), visceral fat depot of the heart, was found to be associated with coronary artery disease in cardiac and non-cardiac patients. Platelet-to-lymphocyte ratio (PLR) and neutrophil-to-lymphocyte ratio (NLR) were introduced as potential markers to determine inflammation in various disorders. Recently, atherogenic index of plasma (AIP) was found to be closely associated with atherosclerosis in general population. Waist circumference is commonly used to assess the risk factors in various metabolic disorders. There has been a well known relation between inflammation and peripheral adipose tissue in diabetes mellitus. However, the data regarding EAT and inflammation is scant in this population. Hence, we aimed to determine the relationship between PLR, NLR, AIP, waist circumference and EAT in diabetic patients. This was a cross-sectional study involving 156 patients with type 2 diabetes mellitus (87 females, 69 males; mean age, 53.62 ± 9.33 years) and 50 control subjects (35 females, 15 males; mean age, 51.06 ± 8.74 years). EAT was measured by using a trans-thoracic echocardiogram. Atherogenic index of plasma was calculated as the logarithmically transformed ratio of the serum triglyceride to high density lipoprotein (HDL)cholesterol. NLR and PLR were calculated as the ratio of the neutrophils and platelets to lymphocytes, respectively. Waist circumference, PLR, NLR, AIP and EAT measurements were significantly higher in diabetic patients when compared to control subjects. When diabetic patients were separated into two groups according to their median value of EAT (Group 1, EAT < 4.53 (n = 78) and group 2, EAT ≥4.53 (n = 78)), group 2 patients had significantly higher Body mass index (BMI), waist circumference, AIP, NLR and PLR levels. In the bivariate correlation analysis, EAT was positively correlated with PLR, NLR, AIP, BMI and waist circumference (r = 0.197, p = 0.014; r = 0.229, p = 0.004; r = 0.161, p = 0.044; r = 0.248, p = 0.002; r = 0.306, p < 0.001, respectively). Waist circumference was found to be independent variables of EAT. Simple calculation of PLR and measurement of waist circumference were found to be associated with increased EAT in diabetic patients.

    [Show abstract] [Hide abstract] ABSTRACT: Introduction: Epicardial adipose tissue (EAT) is the true visceral fat depot of the heart. The relationship between coronary artery disease and EAT was shown in end-stage renal disease (ESRD) patients. One of the established risk factor in this population is dyslipidemia. We aimed to determine the relationship between atherogenic index of plasma (AIP) and EAT in ESRD patients. Methods: This was a cross-sectional study involving 76 ESRD patients receiving PD or HD for ≥6 months and 42 healthy subjects. EAT was measured by using an electrocardiogram-gated 64-multidetector computed tomography (MDCT). Atherogenic index of plasma was calculated as the logarithmically transformed ratio of the serum trigliseride to HDL-cholesterol. Results: The etiology of ESRD patients was diabetic nephropathy (n = 16), chronic glomerulonephritis (n = 10), hypertensive nephropathy (n = 23), polycystic kidney disease (n = 7), nephrolithiasis (n = 5) and unknown (n = 15). There were no differences with respect to the following variables between ESRD patients and healthy subjects: age; sex; BMI; predialysis levels of DBP; serum levels of albumin, HDL-cholesterol and hemoglobin. However, ESRD patients had higher serum levels of trigliseride, hs-CRP and AIP when compared to healthy subjects. There was a statistically significant relationship between EAT, BMI and AIP in ESRD patients (r = 0.42, p < 0.001 and r = 0.25, p = 0.028, respectively). The stepwise linear regression analysis revealed that age, as well as BMI were independent predictors of EAT. Conclusion: We found a relationship between EAT as defined by MDCT and AIP in ESRD patients. Further clinical and experimental studies are needed.

    [Show abstract] [Hide abstract] ABSTRACT: Chronic inflammation was found to be correlated with coronary (CAC) and thoracic peri-aortic calcification (TAC) in end-stage renal disease (ESRD) patients. Neutrophil-to-lymphocyte ratio (NLR) was introduced as a potential marker to determine inflammation in cardiac and noncardiac disorders. Data regarding NLR and its association with TAC and CAC are lacking. We aimed to determine the relationship between NLR and vascular calcification in ESRD patients. This was a cross-sectional study involving 56 ESRD patients (22 females, 34 males; mean age, 49.9 ± 14.2 years) receiving peritoneal dialysis or hemodialysis for ≥6 months in the Dialysis Unit of Necmettin Erbakan University. TAC and CAC scores were measured by using an electrocardiogram-gated 64-multidetector computed tomography. NLR was calculated as the ratio of the neutrophils and lymphocytes. There was a statistically significant correlation between NLR, TACS and CACS in ESRD patients (r = 0.43, P = 0.001 and r = 0.30, P = 0.02, respectively). The stepwise linear regression analysis revealed that age, as well as NLR were independent predictors of TACS. However, increased age was the only independent predictor of CACS according to linear regression analysis. Simple calculation of NLR can predict vascular calcification in ESRD patients.

    [Show abstract] [Hide abstract] ABSTRACT: Neutrophil-to-lymphocyte ratio (NLR) was introduced as a potential marker to determine inflammation in end-stage renal disease (ESRD) patients. Recently, platelet-to-lymphocyte ratio (PLR) and NLR were found to positively correlated with inflammatory markers including tumor necrosis factor-α (TNF-α) and interleukin (IL)-6 in cardiac and noncardiac patients. Data regarding PLR and its association with inflammation are lacking in hemodialysis (HD) and peritoneal dialysis (PD) patients. Hence, we aimed to determine the relationship between PLR, NLR, and inflammation in ESRD patients. This was a cross-sectional study involving 62 ESRD patients (29 females, 33 males; mean age, 49.6 ± 14.6 years) receiving PD or HD for ≥6 months in the Dialysis Unit of Necmettin Erbakan University. PLR, NLR, C-reactive protein, TNF-α, IL-6 levels were measured. PLR, NLR, serum high sensitive C-reactive protein, IL-6, and TNF-α levels were significantly higher in PD patients when compared with HD patients. ESRD patients with PLR ≥ 140 had significantly higher NLR, IL-6, and TNF-α levels when compared to patients with PLR < 139. In the bivariate correlation analysis, PLR was positively correlated with NLR, IL-6, and TNF-α in this population. When we compared the association of PLR and NLR with IL-6 (r = 0.371, P = 0.003 vs. r = 0.263, P = 0.04, respectively) and TNF-α (r = 0.334, P = 0.008 vs. r = 0.273, P = 0.032, respectively), PLR was found to be superior to NLR in terms of inflammation in ESRD patients. Simple calculation of PLR can predict inflammation better than NLR in ESRD patients.

    [Show abstract] [Hide abstract] ABSTRACT: Mean platelet volume (MPV) is a determinant of platelet activation. Atherogenic index of plasma (AIP), which is defined as the logarithm of the ratio of plasma level of triglycerides to the level of high-density lipoprotein (HDL)-cholesterol (log[ TG/HDL-C]), has recently been used as a marker of atherogenicity. This study included 104 normotensive individuals. Mean platelet volume and AIP were measured in all patients. Nondipper individuals (8.6 ± 0.9 fL, 0.3 ± 0.2) demonstrated higher values of MPV and AIP compared with dippers (7.9 ± 1.1 fL, 0.1 ± 0.2) (P < .001 and < .001, respectively). Mean platelet volume and AIP have a positive correlation with insufficient decline in nocturnal blood pressure.
