Recent studies claim that FGF23 is also associated with anemia and inflammation. In this study, the relationship between FGF23 and anemia in hemodialysis (HD) and renal transplantation patients (RTx patients) patients was investigated. This was a cross-sectional study involving 40 RTx patients (13 females, 27 males; mean age, 45.93 ± 12.49 years) who had transplantation at least 6 months before, 25 HD patients (12 females, 13 males; mean age, 54.72 ± 15.5 years), and 20 healthy control subjects (13 females, 7 males; mean age, 36.7 ± 9.38 years). FGF23 was studied using Elisa method. Parameters such as iron, ferritin, total iron binding capacity, and transferrin saturation were assessed. FGF23 level was significantly higher in HD patients when compared with the RTx patients and control groups. In the bivariate correlation analysis, hemoglobin was positively correlated with albumin (r = 0.681, p = 0.000), ferritin (r = 0.446, p = 0.043), and negatively correlated with CRP (r = − 0.476, p = 0.016) and FGF23 (r = 0.493, p = 0.043). FGF23 was found to be an independent predictor of decreased hemoglobin in HD patients. In addition, this association was observed to disappear after transplantation. While FGF23 is closely related to hemoglobin levels in HD patients, we have shown that this relationship disappears after transplantation.

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. 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. 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. 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.

Vascular calcifications that may cause cardiovascular disease are highly prevalent in chronic kidney disease (CKD). In this study, we aimed to determine abdominal aorta calcifications (AAC) in predialysis and hemodialysis patients by lateral lumbar radiography and to investigate factors that were associated with the calcifications.Two hundred and fifty-nine adult chronic hemodialysis patients, 300 predialysis CKD patients and 60 healthy subjects with normal kidney function as a control group were enrolled in the study. Lateral lumbar radiography was used to measure AAC. Calcified deposits of the abdominal aorta wall at the level of the first through fourth lumbar vertebrae were graded by a 24-point scoring system.AAC prevalence (AAC score ≥1) was significantly different in hemodialysis, predialysis and control groups (71.8, 45.7 and 33.3 %, respectively; p 0.001). AAC prevalence in CKD stages 1, 2, 3, 4 and 5 predialysis patients was 26.6, 43.3, 40, 58.3 and 55 %, respectively. AAC scores of the hemodialysis group were higher than of the predialysis group (p 0.001) and the control group (p 0.001). AAC scores of the predialysis group were not higher than of the control group (p = 0.314). AAC scores of the hemodialysis group were significantly higher than of the control group (p 0.001) and stage 1 (p 0.001), stage 2 (p = 0.001) and stage 3 predialysis groups (p = 0.002). Age (p 0.001), presence of diabetes mellitus (p 0.001) and serum phosphorus levels (p = 0.011) were found to be independent predictors of calcification in the hemodialysis group. Age (p 0.001), serum phosphorus levels (p = 0.007) and history of cardiovascular disease (p = 0.014) were found to be independent predictors of calcification in the predialysis group.Abdominal aortic calcification is highly prevalent in the hemodialysis population. Strict phosphorus control should be implemented to the predialysis and hemodialysis patients.

Thoracic peri-aortic fat tissue (PFT) is considered as a metabolically active organ in atherosclerosis. Malnutrition, inflammation and atherosclerosis/calcification (MIAC) are the most commonly encountered risk factors of cardiovascular disease in end-stage renal disease (ESRD) patients. Calcification of the aorta was found to be an important cardiovascular risk marker predicting future events, morbidity and mortality in this population. We aimed to investigate the relationship between PFT, MIAC syndrome and thoracic aortic calcification (TAC) in ESRD patients.Seventy-nine ESRD patients receiving hemodialysis (HD) or peritoneal dialysis (PD) and 20 control subjects were enrolled in this cross-sectional study. PFT and TAC were assessed using a 64-MDCT scanner. Patients with serum albumin3.5 g/dL were defined as patients with malnutrition; those with serum C-reactive protein level10 mg/L had inflammation, and those with coronary artery calcification score (CACS)10 had atherosclerosis/calcification.TAC and PFT were significantly higher in ESRD patients compared with control subjects. There was a statistically significant relationship between PFT and TAC in ESRD patients (r = 0.458, p0.0001). PFT was found to be significantly increased when the MIAC components increased. PFT was positively associated with age, BMI, uric acid, hemoglobin and CAC. The multivariate analysis revealed that age and uric acid were independent predictors of increased PFT. Twenty-four (30.4 %) patients had none, 30 (37.9 %) had one component, 17 (21.5 %) had two components, and 8 (10.2 %) had all MIAC components. PFT was highest among patients having all three components (28.6 cm(3)) and lowest among those who do not have the MIAC syndrome (8.54 cm(3)). TAC was highest among patients having all three components (179.2 HU) and lowest among those who do not have the MIAC syndrome (0 HU).We found a relationship between PFT and MIAC syndrome in ESRD patients.

There is scarce data about effects of treatment of clinical depression in peritoneal dialysis (PD) population. We aimed to determine prevalence of depression, its association with health-related quality of life (HRQoL) and effects of sertraline treatment in PD patients. We included 124 PD patients who had been on PD at least for 6 months. Short Form of Medical Outcomes Study was used to evaluate HRQoL. Depression was screened by Beck Depression Inventory (BDI). Patients with a BDI score ≥17 were deemed to have depression and were referred to a psychiatrist for evaluation via Diagnostic and Statistical Manual for Mental Disorders (DSM-IV) of diagnosis of clinical depression. About 25 patients diagnosed with clinical depression agreed to receive antidepressant treatment (Sertraline hydrochloride, 50 mg/day) for a 12-week period. After the treatment, biochemical analyses and questionnaires were repeated. Thirty-two patients (25.8%) had depression. BDI score of patients were lower compared to those without depressive symptoms (23 ± 6.7 and 9.8 ± 3.0, respectively P
