Abstract
OBJECTIVE COVID-19 immune syndrome is a multi-systemic disorder induced by the COVID-19 infection. Pathobiological transitions and clinical stages of the COVID-19 syndrome following the attack of SARS-CoV-2 on the human body have not been fully explored. The aim of this review is to outline the three critical prominent phase regarding the clinicogenomics course of the COVID-19 immune syndrome. MATERIALS AND METHODS In the clinical setting, the COVID-19 process presents as "asymptomatic/pre-symptomatic phase", "respiratory phase with mild/moderate/severe symptoms" and "multi-systemic clinical syndrome with impaired/disproportionate and/or defective immunity". The corresponding three genomic phases include the "ACE2, ANPEP transcripts in the initial phase", "EGFR and IGF2R transcripts in the propagating phase" and the "immune system related critical gene involvements of the complicating phase". RESULTS The separation of the phases is important since the genomic features of each phase are different from each other and these different mechanisms lead to distinct clinical multi-systemic features. Comprehensive genomic profiling with next generation sequencing may play an important role in defining and clarifying these three unique separate phases for COVID-19. From our point of view, it is important to understand these unique phases of the syndrome in order to approach a COVID-19 patient bedside. CONCLUSIONS This three-phase approach may be useful for future studies which will focus on the clinical management and development of the vaccines and/or specific drugs targeting the COVID-19 processes. ANPEP gene pathway may have a potential for the vaccine development. Regarding the specific disease treatments, MAS agonists, TXA127, Angiotensin (1-7) and soluble ACE2 could have therapeutic potential for the COVID-19 course. Moreover, future CRISPR technology can be utilized for the genomic editing and future management of the clinical course of the syndrome.

Abstract
Natriuretic peptides are structurally similar, but genetically distinct, hormones that participate in cardiovascular homeostasis by regulating blood and extracellular fluid volume and blood pressure. We investigated the distribution of natriuretic peptides and their receptors in goat (Capra hircus) heart tissue using the peroxidase-anti-peroxidase (PAP) immunohistochemical method. Strong staining of atrial natriuretic peptide (ANP) was observed in atrial cardiomyocytes, while strong staining for brain natriuretic peptide (BNP) was observed in ventricular cardiomyocytes. Slightly stronger cytoplasmic C-type natriuretic peptide (CNP) immunostaining was detected in the ventricles compared to the atria. Natriuretic peptide receptor-A (NPR-A) immunoreactivity was more prominent in the atria, while natriuretic peptide receptor-B (NPR-B) immunoreactivity was stronger in the ventricles. Cytoplasmic natriuretic peptide receptor-C (NPR-C) immunoreactivity was observed in both the atria and ventricles, although staining was more prominent in the ventricles. ANP immunoreactivity ranged from weak to strong in endothelial and vascular smooth muscle cells. Endothelial cells exhibited moderate to strong BNP immunoreactivity, while vascular smooth cells displayed weak to strong staining. Endothelial cells exhibited weak to strong cytoplasmic CNP immunoreactivity. Vascular smooth muscle cells were labeled moderately to strongly for CNP. Weak to strong cytoplasmic NPR-A immunoreactivity was found in the endothelial cells and vascular smooth muscle cells stained weakly to moderately for NPR-A. Endothelial and vascular smooth cells exhibited weak to strong cytoplasmic NPR-B immunoreactivity. Moderate to strong NPR-C immunoreactivity was observed in the endothelial and smooth muscle cells. Small gender differences in the immunohistochemical distribution of natriuretic peptides and receptors were observed. Our findings suggest that endothelial cells, vascular smooth cells and cardiomyocytes express both natriuretic peptides and their receptors.

Abstract
Purpose Poor sleep quality (SQ) is common in hemodialysis (HD) patients. Factors associated with poor SQ are not well understood. The objectives of the present study were to determine the prevalence of poor SQ in HD patients in our region and to examine the association between SQ and health-related quality of life (HRQoL), depression, and certain clinical and laboratory parameters. Methods A total of 233 HD patients at 5 centers in the city center of Konya, Turkey were included in this study. Their demographic data and biochemical parameters were analyzed. All patients were instructed to complete Turkish versions of three questionnaires, namely, a modified post-sleep inventory (PSI), Beck Depression Inventory (BDI) and a Short Form of Medical Outcomes Study (SF-36). Results The mean age of the patients was 52.8±15.3 years and the male to female ratio was 1.33:1. The prevalence of poor sleepers, defined as those having a total sleep score (PSI-4 score) ≥ 4, was 60.9%. Compared with good sleepers, poor sleepers had higher BDI scores and as well as lower PCS and MCS domains of HRQoL. In addition, poor sleepers were older and more likely to be unemployed. There was a significant inverse correlation of PSI-4 score with PCS and MCS, and significant positive correlation of PSI-4 score with BDI and age (p<0.001). The significant independent predictors of PSI-4 score were BDI score, MCS score and employment status. Conclusions Depression, MCS score and employment status were the most important predictors of sleep quality in HD patients.

Abstract
BACKGROUND Cytokines are essential mediators of immune response. Chronic renal failure patients suffer from chronic inflammation that results from factors such as impaired renal function, accumulation of uremic toxins and bio incompatibility of dialyzer membranes. These patients are also at increased risk of cardiovascular diseases. We have evaluated cytokines, adipocytokines and inflammatory markers in patients with chronic renal failure undergoing hemodialysis (HD) and continuous ambulatory peritoneal dialysis (CAPD). MATERIAL AND METHODS We have determined serum tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), high-sensitivity C-reactive protein (hsCRP), leptin and ghrelin levels of chronic renal failure patients treated with either HD (n = 20) or CAPD (n = 20). TNF-α, IL-6, ghrelin and leptin measurements were performed by commercially available kits based on enzyme-linked immunosorbent assay (ELISA) method. hsCRP levels were determined by turbidimetric methods. RESULTS Serum TNF-α and IL-6 levels of patients on HD were significantly higher than those of the ones on CAPD (p < 0.05). Ghrelin, leptin and hsCRP concentrations were similar in both groups. CONCLUSIONS We can conclude that cytokine production is more obvious in HD process.

Abstract
BACKGROUND Neutrophil gelatinase-associated lipocalin (NGAL) is a member of the lipocalin family best known as a novel and early marker of acute kidney injury (AKI). Recent data suggest that NGQueryAL is not only a marker of AKI, but also an important player in the vascular remodeling, atherosclerotic plaque stability and thrombus formation. We conducted this study to investigate the association of serum NGAL levels with fatal and composite (fatal and non-fatal) cardiovascular events (CVE) in a cohort of patients with stage 1-5 CKD. METHODS This was an observational cohort study in which serum NGAL was obtained from 298 CKD (stages 1-5) patients. Fatal and composite CVE were recorded for a median 41 months. We examined alteration of serum NGAL through CKD groups as well as association with inflammatory markers. We also performed a Cox regression analysis to determine the association of NGAL with predefined clinical outcomes. RESULTS The median value of NGAL was 50.5 ng/mL (IR 47.6-54.9 ng/mL), and higher NGAL values were recorded in diabetic patients. In a multiple linear regression model, including all univariate associates of NGAL, only log eGFR, log hs-CRP and log HDL cholesterol maintained an independent association with log NGAL. During the observational period, 30 patients died due to cardiovascular causes and 69 non-fatal CVE were registered. In the fully adjusted model, we observed a 2.08-fold increase in the risk of fatal CVE and a 1.50-fold increase in the risk of fatal and non-fatal CVE for each increment of 1 SD in log NGAL values. CONCLUSIONS This is the first study that shows that serum NGAL is associated with cardiovascular events (fatal and non-fatal) in patients with CKD, independently of traditional risk factors, renal function and inflammation.

Abstract
Spontaneous retroperitoneal hemorrhage (SRH) is a rare and potentially fatal condition. Acquired cystic kidney disease (ACKD) may cause SRH in hemodialysis patients. However, presentation of retroperitoneal hematoma as hemoperitoneum in peritoneal dialysis (PD) patients is exceedingly rare. We report a 44-year-old male PD patient who presented with hemoperitoneum secondary to retroperitoneal hematoma. The reason of SRH was rupture of the cysts of ACKD. The patient underwent unilateral nephrectomy with subsequent disappearance of hemoperitoneum. The importance of this case lies in the fact that the patients who have been receiving dialysis for a long time should be under surveillance in terms of ACKD development and potential associated complications such as cyst hemorrhage and malignancy.

Abstract
The erythropoiesis-stimulating agent (ESA) hyporesponsiveness index (EHRI) calculated as the weekly dose of EPO divided by weight (kg) divided by hemoglobin level (g/dL) has been considered useful to assess ESA resistance. Recent evidence suggests that active vitamin D, cinacalcet, and paricalcitol use may be related with lower ESA resistance. We conducted this observational cross-sectional study to investigate ESA resistance calculated by the EHRI among patients using calcitriol, cinacalcet, and paricalcitol. Participants underwent a medical history taken, physical examination, measurement of biochemical analysis, calculation of dialysis adequacy, and EHRI. Sixty-five patients did not receive any treatment regarding vitamin D, paricalcitol, and cinacalcet (group 1), 41 were taking only vitamin D (group 2), 50 were taking only paricalcitol (group 3), 19 were taking only cinacalcet (group 4), and 21 were taking paricalcitol + cinacalcet (group 5). The EHRI values for groups 1, 2, 3, 4, and 5 were 11.36 ± 8.72, 11.58 ± 5.72, 8.29 ± 5.54, 9.49 ± 4.61, and 8.91 ± 4.44 respectively (P =.034). Post hoc analysis showed that the EHRI differed between group 1 and group 3 (P =.017) and between group 2 and group 3 (P =.006). In linear regression analysis, use of paricalcitol was independently associated with EHRI. In conclusion, paricalcitol use was associated with lower EHRI levels as a measure of ESA resistance.

Abstract
OBJECTIVES Acute kidney injury (AKI) is a common complication of cardiac surgery developing in 25-35% cases. Recently, neutrophil gelatinase-associated lipocalin (NGAL) was shown to predict AKI development earlier than serum creatinine. Some studies demonstrated the predictive role of post-operative serum uric acid (SUA) as an early marker of AKI. We aimed to study the role of serum and urine NGAL as well as SUA to predict progression of AKI. DESIGN AND METHODS This is a prospective observational study of patients undergoing cardiac surgery. Blood and urine samples for measurement of uric acid, serum and urine NGAL levels were collected prior to cardiac surgery (0 h), and in the time course at 2nd and 24th hours after surgery. Patients who developed AKI were divided into two subgroups as progressing and non-progressing AKI. RESULTS Sixty patients (42 males, 18 females) were included. After cardiac surgery, 40 patients developed AKI, 20 of whom non-progressing AKI, and 20 progressing AKI. All of the markers significantly increased in AKI patients. A receiver operator characteristics (ROC) curve analysis showed higher predictive ability of SUA for progressing AKI compared with serum and urine NGAL. When compared markers obtained at the second hour after surgery, UA had significantly large AUC than NGAL to predict AKI developed at 24 and 48 h, particularly in patients, who require renal replacement therapy (RRT). CONCLUSION Uric acid seems to predict the progression of AKI and RRT requirement in patients underwent cardiac surgery better than NGAL.

Abstract
AIMS CYP53A15, from the sorghum pathogen Cochliobolus lunatus, is involved in detoxification of benzoate, a key intermediate in aromatic compound metabolism in fungi. Because this enzyme is unique to fungi, it is a promising drug target in fungal pathogens of other eukaryotes. METHODS AND RESULTS In our work, we showed high antifungal activity of seven cinnamic acid derivatives against C. lunatus and two other fungi, Aspergillus niger and Pleurotus ostreatus. To elucidate the mechanism of action of cinnamic acid derivatives with the most potent antifungal properties, we studied the interactions between these compounds and the active site of C. lunatus cytochrome P450, CYP53A15. CONCLUSION We demonstrated that cinnamic acid and at least four of the 42 tested derivatives inhibit CYP53A15 enzymatic activity. SIGNIFICANCE AND IMPACT OF THE STUDY By identifying selected derivatives of cinnamic acid as possible antifungal drugs, and CYP53 family enzymes as their targets, we revealed a potential inhibitor-target system for antifungal drug development.

Abstract
INTRODUCTION Erectile dysfunction (ED) is a frequent complaint of elderly subjects and is closely associated with endothelial dysfunction and cardiovascular disease (CVD). Uric acid is also associated with endothelial dysfunction, oxidative stress, and CVD, raising the hypothesis that an increased serum uric acid might predict ED in patients who are at risk for coronary artery disease (CAD). AIM This study aims to evaluate the association of serum uric acid levels with presence and severity of ED in patients presenting with chest pain of presumed cardiac origin. METHODS This is a cross-sectional study of 312 adult male patients with suspected CAD who underwent exercise stress test (EST) for workup of chest pain and completed a sexual health inventory for men survey form to determine the presence and severity of ED. Routine serum biochemistry (and uric acid levels) were measured. Logistic regression analysis was used to assess risk factors for ED. MAIN OUTCOME MEASURES The short version of the International Index of Erectile Function questionnaire diagnosed ED (cutoff score ≤ 21). Serum uric acid levels were determined. Patients with chest pain of suspected cardiac origin underwent an EST. RESULTS One hundred forty-nine of 312 (47.7%) male subjects had ED by survey criteria. Patients with ED were older and had more frequent CAD, hypertension, diabetes and impaired renal function, and also had significantly higher levels of uric acid, fibrinogen, glucose, C-reactive protein, triglycerides compared with patients without ED. Uric acid levels were associated with ED by univariate analysis (odds ratio = 1.36, P = 0.002); however, this association was not observed in multivariate analysis adjusted for estimated glomerular filtration rate. CONCLUSION Subjects presenting with chest pain of presumed cardiac origin are more likely to have ED if they have elevated uric acid levels.

Abstract
Background Cardiovascular risk is increased in the early stages of chronic kidney disease (CKD) and also found to be ongoing in renal transplant (Rtx) patients. As a sign of atherosclerosis, increased carotid intima-media thickness (CIMT) has been widely accepted as a strong predictor of cardiovascular disease (CVD) and mortality in CKD patients. A novel markers, soluble tumor necrosis factor-like weak inducer of apoptosis (sTWEAK) and neutrophil-to-lymphocyte ratio (NLR) were introduced as potential markers in inflammatory disorders including CKD. The role of Rtx in terms of atherogenesis is still unclear. We aimed to investigate the relationship between sTWEAK, NLR and CIMT in Rtx patients without overt CVD and to compare these results with those obtained from healthy subjects. Methods Cross-sectional analysis in which CIMT measurements, NLR and serum TWEAK levels were assessed in 70 Rtx patients (29 females; mean age, 40.6 ± 12.4 years) and 25 healthy subjects (13 females, mean age; 37.4±8.8 years). Results sTWEAK levels were significantly decreased (p=0.01) and hs-CRP, NLR and CIMT levels of Rtx patients were significantly increased compared to healthy subjects (p<0.0001, p=0.001, p<0.0001, respectively). sTWEAK was also found to be decreased when eGFR was decreased (p=0.04 between all groups). CIMT was positively correlated with sTWEAK and NLR in Rtx patients (r=0.81, p<0.0001 and r=0.33, p=0.006, respectively). sTWEAK was also positively correlated with NLR (r=0.37, p=0.002). In the multivariate analysis only sTWEAK was found to be an independent variable of increased CIMT. Conclusion sTWEAK might have a role in the pathogenesis of ongoing atherosclerosis in Rtx patients.

Abstract
PURPOSE Arterial hypertension is a risk factor affecting graft function in renal transplant recipients (RTRs). In pediatric RTRs, high prevalence of masked and nocturnal hypertension was reported. Most of the RTRs had a history of hypertension and some of them were normotensive at outpatient visits whereas home blood pressure (BP) levels were higher. Masked hypertension (MHT) is defined as a normal office BP but an elevated ambulatory BP. Previous reports have demonstrated the detrimental role of MHT in clinical outcomes in hypertensive patients. However, the true prevalence of MHT in RTRs is yet to be defined. METHODS A total of 113 RTRs (mean age 44 ± 16 years, 72 males, 41 females) with normal office BP (< 140/90 mmHg) were enrolled to the study from the outpatient renal transplantation clinic. Ambulatory BP monitoring (ABPM) was performed in all participants for a 24-h period. Average daytime BP values above 135 mmHg systolic and 85 mmHg diastolic were defined as MHT. RESULTS The prevalence of MHT in our cohort was 39% (n = 45). Fasting glucose and C-reactive protein levels were higher in patients with MHT compared with normal BP group (p = 0.02 and p = 0.04, respectively). RTRs with deceased donor type had higher prevalence of MHT than RTRs with living donor (40% vs 19%, p = 0.003). In multivariate analysis, deceased donor type could predict the MHT independent of age, gender, office systolic BP level, diabetes mellitus, serum creatinine, C-reactive protein, and glucose levels (OR = 3.62, 95% CI 1.16-11.31, p = 0.03). CONCLUSION We demonstrated an increased prevalence of MHT in a typical renal transplant cohort. In addition, transplantation from a deceased donor may be a predictor of MHT. The prevalence of MHT may help to explain high rate of cardiovascular events in RTRs. Therefore, routine application of ABPM in RTRs may be plausible, particularly in RTRs with deceased donor type.

Abstract
AIM Pruritus is common in dialysis patients. Peripheral neuropathy is also prevalent in this patient population. However, the role of neuropathy in the genesis of uraemic itch has not been adequately studied to date. Therefore, we aimed to investigate the effects of gabapentin and pregabalin on uraemic pruritus along with neuropathic pain in patients receiving haemodialysis. METHODS This is a 14 week long randomized, prospective, cross-over trial. Haemodialysis patients with established neuropathy and/or neuropathic pain were included. Fifty patients were randomly assigned to gabapentin 300 mg after each haemodialysis session and pregabalin 75 mg daily. After 6 weeks of treatment, cross-over was performed and patients received the other drug for another 6 weeks. Short Form of McGill Pain Questionnaire and Visual Analogue Scale were used to evaluate pain and pruritus, respectively. At each week's visit, patients were interrogated in terms of adverse effects of study drugs. Baseline laboratory data and demographic characteristics were recorded from patient charts. RESULTS Forty (12 males, 28 females) out of 50 patients completed the study. Mean age was 58.2 ± 13.7. Overall, 29 out of 40 patients (72.5%) had pruritus symptoms at baseline evaluation. Fifteen patients (37.5%) were diabetic. Thirty-one out of 40 patients (77.5%) had electromyography (EMG)-proven peripheral neuropathy. Twenty three patients (57.5%) had both EMG-proven neuropathy and pruritus. Gabapentin and pregabalin improved both neuropathic pain and pruritus significantly. There was no difference between the study drugs in terms of efficacy against pain and pruritus. CONCLUSION Treatment of neuropathic pain with either pregabalin or gabapentin effectively ameliorates uraemic itch.

Abstract
Coenzyme Q10 (CoQ10) supplementation has been shown to improve diastolic heart function in various patient cohorts. Systolic and diastolic dysfunctions are common in patients with end-stage renal disease. Favorable effects of CoQ10 on cardiac functions are yet to be seen in hemodialysis patients. We aimed to evaluate effect of CoQ10 supplementation on diastolic function in a cohort of maintenance hemodialysis patients. This was a prospective, double-blind, placebo-controlled, crossover study in which all patients received placebo and oral CoQ10 200 mg/d during the 8 weeks in each phase, with a 4-week washout period. Participants underwent conventional and tissue Doppler echocardiography before and after each study phase. Parameters characterizing left ventricle diastolic function and other standard echocardiographic measurements were recorded. Twenty-eight patients were randomized, but 22 patients completed study protocol. Intraventricular septum (IVS) thickness and left ventricle mass were significantly decreased in CoQ10 group (P = 0.03 and P = 0.01, respectively). Myocardial peak systolic and early diastolic velocities derived from IVS were significantly increased (P = 0.048 and P = 0.04, respectively). Isovolumetric relaxation time and E/Em ratio calculated for IVS also significantly reduced in CoQ10 group (p = 0.02 and p = 0.04, respectively). There was no significant difference in any of the studied echocardiographic parameters in placebo group. The results of this study showed that CoQ10 supplementation did not significantly improved diastolic heart functions compared with placebo in maintenance hemodialysis patients.

Abstract
Unintentional weight loss in a renal transplant recipient is an important condition, requiring diagnostic search within the framework of malignancy and opportunistic infections. To the best of our knowledge, there are no data in the literature reporting underlying coeliac disease as the cause of significant weight loss after renal transplant. We report a 32-year-old woman, who complained of significant weight loss during the 3.5 years posttransplant. Diagnostic work-up revealed coeliac disease, and a gluten-free diet stabilized her weight loss. Considering the high frequency of coeliac disease, this should be kept in the differential diagnosis of renal transplant recipients presented with weight loss and other suggestive features.

Abstract
BACKGROUND/AIMS: Atherosclerosis and inflammation are the most important risk factors in the pathogenesis of cardiovascular diseases (CVD) in patients with end-stage renal disease (ESRD). Pentraxin-3 (PTX-3) was shown to predict inflammation and atherosclerosis in ESRD patients. However, the role of renal transplantation (Rtx) in terms of atherogenesis is still unclear. We aimed to investigate the relationship between PTX-3, neutrophil-to-lymphocyte ratio (NLR), and carotid intima-media thickness (CIMT) in Rtx patients and healthy controls. METHODS: This was a cross-sectional study involving 29 Rtx patients (12 females, 40.1 ± 11.9 years) without overt CVD and 19 healthy subjects (9 females, 36.9 ± 8.9 years), testing the relationship between CIMT, assessed by ultrasonography, and selected biomarkers. RESULTS: CIMT, PTX-3, and high-sensitivity C-reactive protein (hs-CRP) levels of Rtx patients were found to be significantly higher compared to healthy subjects. CIMT was positively correlated with age, creatinine, uric acid, triglyceride, PTX-3, hs-CRP, and NLR, and negatively correlated with estimated glomerular filtration rate in all participants. In Rtx patients, CIMT was positively correlated with age, BMI, serum phosphorus, low-density lipoprotein, and hs-CRP. The multivariate analysis revealed that hs-CRP was found to be an independent variable of CIMT in Rtx patients. CONCLUSION: Our data showed that inflammation and atherosclerosis persist in Rtx patients. Serum hs-CRP might be a useful marker to assess these parameters in this population.

Abstract
OBJECTIVES Cardiovascular risk is increased in the early stages of chronic kidney disease (CKD) and is also found to be ongoing in renal transplant (Rtx) patients. As a sign of atherosclerosis, increased carotid intima-media thickness (CIMT) has been widely accepted as a strong predictor of cardiovascular disease (CVD) and mortality in the end-stage renal disease (ESRD) patients. Ischemia-modified albumin (IMA), pentraxin-3 (PTX-3), and neutrophil-to-lymphocyte ratio (NLR) were introduced as oxidative stress and inflammatory biomarkers in ESRD. The role of Rtx in terms of atherogenesis, oxidative stress, and inflammation is still unclear. We aimed to investigate the relationship between IMA, PTX-3, NLR, and CIMT in Rtx patients without overt CVD and to compare these results with those obtained from healthy subjects and ESRD patients receiving hemodialysis (HD) and peritoneal dialysis (PD). DESIGN AND METHODS Cross-sectional analysis in which CIMT measurements, NLR, and serum PTX-3 and IMA levels were assessed in 18 Rtx patients (10 females; mean age: 40.0 ± 13.3 years), 16 PD patients (7 females; 40.2 ± 12.9 years), 14 HD patients (8 females; 46.6 ± 10.7 years), and 19 healthy subjects (9 females; 36.9 ± 8.9 years). RESULTS IMA, PTX-3, and high-sensitive C-reactive protein (hs-CRP) levels, NLR, and CIMT of Rtx patients were found to be significantly higher compared with healthy subjects ( p = 0.04, p < 0.0001, p < 0.005, p = 0.005, and p = 0.005, respectively). IMA level was positively correlated with hs-CRP and PTX-3 levels, NLR, and CIMT when all participants were included (r = 0.338, p = 0.005; r = 0.485, p < 0.0001; r = 0.304, p = 0.013; and r = 0.499, p < 0.0001, respectively). CONCLUSION There has been ongoing inflammation, oxidative stress, and atherosclerosis in Rtx patients.

Abstract
Brucellosis is a zoonotic infection that humans contract usually by ingestion of unpasteurized milk and milk products or by direct contact with raw infected animal products. Infection is endemic in many countries, including Turkey. Being a systemic disease, brucellosis may affect almost any part of the body. The peritoneum is a site rarely involved in brucellosis. Most peritonitis episodes involving Brucella species have been spontaneous cases reported in cirrhotic patients with ascites. To our knowledge, the literature contains only 5 cases of Brucella peritonitis related to continuous ambulatory peritoneal dialysis. Here, we report Brucella peritonitis in a continuous ambulatory peritoneal dialysis patient, and we discuss the relevant literature.

Abstract
Despite all developments in hemodialysis (HD), the mortality rate is still apparently higher than that in the general population, and worse health-related quality of life (HRQOL) is associated with increased mortality. We prospectively investigated the mortality status of HD patients during a five-year period and the association between mortality, HRQOL, laboratory parameters and clinical and sociodemographic characteristics at baseline. At the end of the five years, 293 patients out of 420 patients were still on HD treatment and 127 patients died. Those who died had a higher mean age, lower mean values of serum creatinine and albumin, higher prevalence of diabetes mellitus, received more HD twice weekly for less than 4 h in almost all HD sessions and had lower HRQOL than the survivors. We conclude that age, comorbidity, HD sessions lasting less than 4 h, malnutrition [hypoalbuminemia, low body mass index (BMI)] and lower physical component scores of SF-36 survey (PCS) were associated with higher risk of death in the HD population.

Abstract
BACKGROUND Cardiovascular disease is the leading cause of mortality in endstage renal failure. Prognostic role of echocardiography has not been fully elucidated in chronic hemodialysis patients. AIM To assess the ability of Doppler echocardiographic parameters of left ventricular (LV) diastolic function along with conventional echocardiographic indices to predict long-term adverse major events in chronic hemodialysis patients with normal LV ejection fraction (EF). PATIENTS AND METHODS A total of 45 chronic hemodialysis patients (aged 49 +/- 15 years) were included to the study. All patients underwent complete standard and tissue Doppler imaging echocardiography before and immediately after hemodialysis session and were followed-up prospectively. Major outcome measure was the combination of all-cause death and hospitalization for any cardiovascular event. RESULTS During the follow up period (52 +/- 26 months) 23 major events occured (17 all-cause deaths and 6 cardiovascular events requring hospitalization). Post-dialytic values of mean left atrial diameter, mitral E (peak early mitral inflow velocity), E/Vp [ratio of mitral E to flow propagation velocity (Vp)] and E/Ea [ratio of mitral E to peak early diastolic mitral annular velocity (Ea)] (average of 4 segments of mitral annulus) were significantly higher in patients who had major events. In Cox proportional hazard analysis only E/Ea ratio predicted combined endpoint of all-cause mortality and nonfatal cardiovascular events (hazard ratio: 1.20; confidence interval: 1.03-1.39; p = 0.018). The optimum cut-off value for E/Ea determined by ROC curve analysis revealed that E/Ea ratio higher than 9.8 predicted future events with sensitivity of 74% and specificity of 86%. CONCLUSIONS E/Ea might be an accurate echocardiographic indice during long-term follow up for the prediction of major adverse events in chronic hemodialysis patients with normal LV EF.

Abstract
PURPOSE A few studies investigated renal size using computed tomography (CT) in middle-aged and elderly patients while taking renal function into account. Thus, we aimed to assess kidney dimensions and their predictors in patients without known renal disease by multi-detector computed tomography (MDCT). METHODS This is a 6-month-long prospective observational study. Estimated glomerular filtration rate (eGFR) was calculated with Cockcroft-Gault (CG) and modification of diet in renal disease (MDRD) formulas. Pole-to-pole kidney length (R1) was determined from coronal and sagittal oblique images. Kidney length (R2), width (R3), and parenchymal thickness were measured in axial slices. RESULTS The data of the 930 patients were included in this study. CG-eGFR was more closely correlated with R1, R2, and R3 than MDRD-eGFR. CG-eGFR, female gender, and presence of diabetes mellitus were independent predictors of R1 size in logistic regression analyses. CONCLUSION Kidney sizes diminish with advancing age. CG-eGFR shows a better correlation with kidney dimensions compared with MDRD. Overall, age was a stronger determinant of eGFR than renal dimensions.

Abstract
PURPOSE End stage renal disease (ESRD) cases are associated with increased risk of tuberculosis. There is no gold standard method for detecting latent tuberculosis infection (LTBI) in ESRD. The aim of the present study was to analyze the performance of the tuberculin skin test (TST) and QuantiFERON-TB Gold in tube (QFT-G) in cases receiving hemodialysis (HD). METHODS The TST and QFT-G were prospectively performed in 96 ESRD cases undergoing HD. The agreement of the QFT-G and TST was assessed in two TST cut off values (10 mm and 5 mm) in Bacille Calmette Guèrin (BCG) vaccinated and non-vaccinated cases. RESULTS Of 96 cases 67 were BCG vaccinated and 29 were BCG non-vaccinated. QFT-G was positive in 39.6% cases and indeterminate in 3.1%. TST was positive in 43.8% of cases in cut off value of 10 mm and positive in 58.3% of cases in cut off value of 5 mm. Agreement between TST and QFT-G results was fair in both BCG vaccinated and non-vaccinated cases in either cut off values, except in cut off value of 10 mm in BCG vaccinated cases in which the agreement was moderate. CONCLUSION The agreement between QFT-G and TST test is fair and there is no significant difference in both cut off values of TST in screening of LTBI in ESRD cases receiving HD.
