Background: Patients with end-stage renal disease (ESRD) have elevated serum levels of inflammatory mediators including C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), and interleukin (IL)-6. Systemic inflammation was found to be correlated with coronary artery disease (CAD) in this population. Neutrophil-to-lymphocyte ratio (NLR) was introduced as a potential marker to determine inflammation in cardiac and non-cardiac disorders. Data regarding NLR and its association with inflammation are lacking. We aimed to determine the relationship between NLR and inflammation in ESRD patients. Material and methods: This was a cross-sectional study involving 61 ESRD patients (25 females and 36 males; mean age: 48.3 ± 14.5 years) receiving peritoneal dialysis (PD) or hemodialysis (HD) for ≥6 months in the Dialysis Unit of Selcuk University. NLR, CRP, TNF-α, and IL-6 levels were measured. Results: NLR, serum CRP, IL-6, and TNF-α levels were significantly higher in PD patients when compared with HD patients. ESRD patients with NLR ≥ 3.5 had significantly higher TNF-α levels when compared with patients with NLR < 3.5. In the bivariate correlation analysis, NLR was positively correlated with TNF-α in this population. Conclusions: Simple calculation of NLR can predict inflammation in ESRD patients.

The prevalence of diabetes mellitus (DM) is increasing secondary to increased consumption of food and decreased physical activity worldwide. Hyperglycaemia, insulin resistance and hypertrophy of pancreatic beta cells occur in the early phase of diabetes. However, with the progression of diabetes, dysfunction and loss of beta cells occur in both types 1 and 2 DM. Programmed cell death also named apoptosis is found to be associated with diabetes, and apoptosis of beta cells might be the main mechanism of relative insulin deficiency in DM. Autophagic cell death and apoptosis are not entirely distinct programmed cell death mechanisms and share many of the regulator proteins. These processes can occur in both physiologic and pathologic conditions including DM. Besides these two important pathways, endoplasmic reticulum (ER) also acts as a cell sensor to monitor and maintain cellular homeostasis. ER stress has been found to be associated with autophagy and apoptosis. This review was aimed to describe the interactions between apoptosis, autophagy and ER stress pathways in DM.

Despite the improvements in diagnostic tools and medical applications, cardiovascular diseases (CVD), especially coronary artery disease (CAD), remain the most common cause of morbidity and mortality in patients with chronic kidney disease (CKD). The main factors for the heightened risk in this population, beside advanced age and a high proportion of diabetes and hypertension, are malnutrition, chronic inflammation, accelerated atherosclerosis, endothelial dysfunction, coronary artery calcification, left ventricular structural and functional abnormalities, and bone mineral disorders. Chronic kidney disease is now recognized as an independent risk factor for CAD. In community-based studies, decreased glomerular filtration rate (GFR) and proteinuria were both found to be independently associated with CAD. This paper will discuss classical and recent epidemiologic, pathophysiologic, and clinical aspects of CAD in CKD patients.

Summary: Background and objectives: Malnutrition, inflammation, atherosclerosis/calcification (MIAC) and endothelial dysfunction are the most commonly encountered risk factors in the pathogenesis of cardiovascular disease in ESRD patients. Epicardial adipose tissue (EAT) is the true visceral fat depot of the heart. The relationship between CAD and EAT was shown in patients with high risk of coronary artery disease. In this study, we aimed to investigate the relationship between EAT and MIAC syndrome in ESRD patients. Design, setting, participants, & measurements: Eighty ESRD patients and 27 healthy subjects enrolled in this cross-sectional study. EAT and coronary artery calcification score were measured by a multidetector computed tomography (MDCT) scanner. Patients with serum albumin 10 ng/dl (normal range, 0–5 ng/dl) had inflammation; and those with CACS >10 had atheroscleosis/calcification. Results: Total CACS and EAT measurements were significantly higher in ESRD patients when compared with healthy subjects. There was a statistically significant relationship between EAT and CACS in ESRD patients (r = 0.48). EAT measurements were higher in PD patients than HD patients. Twenty-four of the patients had no component, 31 had one component, 17 had two components, and nine had all of the MIAC components. EAT was found to be significantly increased when the presence of MIAC components increased. EAT was positively correlated with age, body mass index, and presence of MIAC. These parameters were also found as independent predictors of increased EAT. Conclusions: We found a relationship between EAT and components of MIAC syndrome in ESRD patients.
