- Background: The primary aim of this study was to assess whether a fixed protocol, using a specially trained team, for intermediate follow-up to fulfillment of guideline targets is non-inferior to conventional follow-up in the care of uraemic patients. A secondary aim was to investigate possible impact on patient outcome.Methods: The cohort comprised 424 patients from seven centers. Inclusion criteria were either serum creatinine exceeding 200 mu mol/l or calculated clearance below 30 ml/min, representing CKD 4 or 5a. Six centers followed a standardized protocol (group 1). One center provided controls (group 2). The study design was prospective and interventional. The variables measured were blood hemoglobin, bicarbonate, calcium, phosphate, intact parathyroid hormone, albumin, renal function variables, blood pressure and RAAS blockade. The number of patients achieving the set goals was analyzed as a time trend to determine if the intervention resulted in an improvement.Results: At baseline, group 1 had significantly lower GFR and higher serum creatinine, calcium, phosphate, calcium x phosphate product and bicarbonate, lower mean arterial pressure (MAP), systolic blood pressures and less use of RAAS. During the intervention, group 1 improved in the direction of guidelines for blood hemoglobin, albumin, bicarbonate and MAP. Outcome of secondary endpoints gave a risk of death of 30% in both groups, while the risk of renal replacement therapy was higher in group 1.Conclusions: However, the time to renal replacement therapy was significantly shorter in the intervention group, indicating that other variables than guideline achievements are important for the patient.

- Background: Sex-specific trends over time with respect to kidney graft survival have scarcely been described in earlier studies. The present study aimed to examine whether kidney graft survival differs between women and men over time.Methods: This study was based on prospectively collected data extracted from a quality registry including all kidney transplant patients between January 1965 and September 2017 at the transplantation center of a university hospital in Sweden. The transplantation center serves a population of approximately 3.5 million inhabitants. Only the first graft for each patient was included in the study resulting in 4698 transplantations from unique patients (37% women, 63% men). Patients were followed-up until graft failure, death, or the end of the study. Death-censored graft survival analysis after kidney transplantation (KT) was performed using Kaplan-Meier analysis with log-rank test, and analysis adjusted for confounders was performed using multivariable Cox regression analysis.Results: Median age at transplantation was 48 years (quartiles 36–57 years) and was similar for women and men. Graft survival was analyzed separately in four transplantation periods that represented various immunosuppressive regimes (1965-1985, 1986–1995, 1996–2005, and 2006–2017). Sex differences in graft survival varied over time (sex-by-period interaction, p = 0.026). During the three first periods, there were no significant sex differences in graft survival. However, during the last period, women had shorter graft survival (p = 0.022, hazard ratio (HR) 1.71, 95% confidence interval (CI) 1.1–2.7, adjusted for covariates). Biopsy-proven rejections were more common in women.Conclusions: In this registry-based study, women had shorter graft survival than men during the last observation period (years 2006–2017).

- Neutrophil-lymphocyte ratio (NLR) is a marker of systemic inflammation that has been shown to predict mortality in patients with malignancies, ischemic heart disease and peripheral vascular disease. Its prognostic value in hemodialysis patients is unclear. The aims of this study were to: (i) explore the relationship between NLR and other biochemical parameters and (ii) to examine the value of NLR as a predictor of cardiovascular and all-cause mortality in hemodialysis patients. The study included all the incident hemodialysis patients from a single center between 2007 and 2012. NLR was calculated using samples obtained 3 months after commencing hemodialysis. One hundred seventy hemodialysis patients were included with a median follow-up of 37 months. There were 54 deaths (32%). NLR was positively correlated with C-reactive protein (r=0.24, p=0.0023) and negatively correlated with hemoglobin (r=-0.27, p=0.00048), albumin (r=-0.23, p=0.0034) and total cholesterol (r=-0.17, p=0.049) levels. In multivariate Cox regression, NLR was independently associated with both all-cause mortality (adjusted hazard ratio [HR] 1.4; 95% confidence interval [CI], 1.2-1.6; p0.0001) and cardiovascular death (HR 1.3, 95% CI 1.1-1.6, p=0.0032). Other predictors of all-cause mortality were age (HR 1.6 per decade; 95% CI, 1.2-2.1; p=0.0017), body mass index (HR 0.93; 95% CI, 0.88-0.98; p=0.0047), albumin (HR 0.91; 95% CI, 0.86-0.97; p=0.0035) and peripheral vascular disease (HR 2.7; 95% CI, 1.4-5.1; p=0.0023). NLR is a practical, cost-efficient and easy to use predictor of cardiovascular and all-cause mortality in incident hemodialysis patients.
