Background and Aim. Chronic kidney disease (CKD) and its final stage: end-stage renal disease (ESRD), are common clinical conditions. Endocan is a human endothelial cell-specific molecule produced by endothelial cells. Its production is related to activation of endothelium and angiogenesis. In this study, we assessed the relation between serum endocan levels and subclinical atherosclerosis (SCA) in CKD and hemodialysis (HD) patients. Subjects and Methods. The present case control study enrolled 30 patients on regular HD for at least 6 months, 30 patients with CKD, and 30 age and sex-matched healthy controls. All participants were subjected to careful history taking and thorough clinical examination. Laboratory investigations included complete blood count, kidney functions, and serum cholesterol, triglycerides, calcium, phosphorus, albumin, PTH, hsCRP, and endocan levels. Results. HD and CKD groups had significantly higher endocan levels when compared with control group (median (IQR): 519.0 (202.3–742.0) versus 409.0 (245.3–505.3) and 273.0 (168.0–395.5) ng/L, respectively). Also, HD patients had significantly higher endocan levels when compared with CKD levels. HD patients had significantly higher carotid intima-media thickness (CIMT) when compared with CKD patients (median (IQR): 0.80 (0.80–0.90) versus 0.75 (0.73–0.75) mm, p < 0.001 ). HD patients had significantly higher frequency of SCA when compared with CKD patients (46.7% versus 13.3%, p = 0.005 ). Patients with SCA had significantly higher hsCRP (median (IQR): 36.5 (26.8–43.5) versus 24.0 (15.8–29.0) mg/dl) and endocan levels (697.0 (528.3–974.8) versus 222.5 (158.8–565.8) ng/L) when compared with patients without SCA. ROC curve analysis of endocan for identification of SCA in HD patients showed that at a cutoff of 380.5 ng/L, endocan has an AUC of 0.862 with a sensitivity and specificity of 92.9% and 68.7%, respectively. Conclusions. Serum endocan levels are related to SCA in HD patients. In addition, it is associated with the hyperinflammatory state in those patients.

Purpose Diabetes is a documented risk factor for peripheral neuropathy. It was reported that associated hypertension could increase this risk. The present study aimed to assess the effect of hypertension and diabetes on median nerve using high-resolution ultrasound. Methods The study includes 50 hypertensive patients (HTN group), 50 diabetic patients (DM group), 50 patients with coexisting diabetes and hypertension (HTN + DM group) and 50 healthy controls. Median nerve affection in the studied groups was studied by vibration perception thresholds (VPT). The median nerve cross-sectional area was determined at the nerve cross-sectional area of the median nerve at the carpal tunnel by high-resolution ultrasound. Clinical symptoms were assessed using Toronto Clinical Severity Score (TCSS). Results There was significantly higher median nerve CSA in all patient groups in comparison to controls. HTN + DM group had significantly higher median nerve CSA when compared with DM group. Patients with peripheral neuropathy in HTN + DM and DM groups had significantly higher median nerve CSA than patients without. Using ROC curve analysis, it was shown that median CSA could successfully distinguish patients with peripheral neuropathy from patients without in HTN + DM group [AUC (95% CI): 0.71 (0.54–0.89)] and in DM group [AUC (95% CI): 0.86 (0.72–0.99)]. Conclusion Hypertensive patients with and without diabetes have significantly higher median nerve CSA when compared with controls.

Background: Neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), and prognostic nutritional index (PNI), are immunonutritional indices, have been shown as an independent factor to predict postoperative recurrence and/or overall survival in patients with hepatocellular carcinoma (HCC). Aim: to validate neutrophils-to-lymphocytes ratio (NLR) as a predictor of post radiofrequency ablation recurrence of hepatocellular carcinoma (HCC). Patients and methods: This cross sectional prospective study was conducted on 50 Egyptian patients had radiofrequency ablation for HCC within Barcelona clinical liver cancer (BCLC) stage A. Pre-treatment laboratory tests and imaging were used to measure NLR, PLR, PNI, Child-Pugh (CTP score, tumor number and tumor size. HCC recurrences were followed after three month. Results: According to NLR cutoff value, the patients with NLR >1.73 had larger tumour size, and higher rates of tumor multiplicity .After 3 month follow up 30/50 (60%) patients had tumour recurrence. Regarding recurrence after RFA showed that CTP class B (P<0.05), tumor size (P<0.05), higher rates of tumor multiplicity (P<0.05), decrease PNI (P<0.001) and increased NLR (P<0.05) after RFA and at baseline were found to be worse prognosis. A receiver-operating characteristic (ROC) analysis was used to classify patients as follows: NLR-PNI 0 group (NLR≤1.73 and PNI > 11.74), NLR-PNI 1 group (NLR > 1.73 or PNI ≤ 11.74) and NLR-PNI 2 group (NLR > 1.73 and PNI ≤ 11.74). The patients with NLR-PNI 2 group had increase in number of portahepatis lymph node, number and size of tumor, decrease serum albumin and change in PNLR. Multivariate analyses suggested increased NLR (hazard ratio [HR] =2.09; 95% confidence interval [CI] =1.88-2.55; P<0.05), increased PLR (HR=0.07; 95% CI=0.06-0.08; P<0.05), and increased AFP (HR=59.20; 95% CI=-99.74-638.78; P<0.05) contributed to post-RFA mortality. Conclusion: High blood NLR after RFA is a predictor for worse survival and also can predict recurrence of HCC. Higher NLR-PNI score predict a worse prognosis in patients who underwent RFA.
