BACKGROUND: The prevalence of disability in CKD is high. In this context the aim of the present study was to assess the  temporal trends of prevalence and disability progression for chronic kidney disease (CKD) caused by specific etiologies. METHODS: Using data from the Global Burden of Diseases Study (GBD) 2019, we examined the age-standardized rates of CKD prevalence and disability-adjusted life-years for different etiologies, including Type 1/2 diabetes mellitus (T1DM/T2DM), glomerulonephritis, and hypertension...

BACKGROUND: Increased intraperitoneal pressure is associated with abdominal wall complications and technical failure of peritoneal dialysis (PD). Several equations have been developed to estimate intraperitoneal pressure. We aimed to assess the prognostic yield of the intraperitoneal pressure as estimated by current equations on the occurrence of abdominal wall complications in peritoneal dialysis patients. METHODS: This is a retrospective analysis of data from a prospective cohort which recruited 1207 incident PD patients...

Vascular calcification is a common complication in patients with chronic kidney disease (CKD) and is strongly associated with an increased risk of cardiovascular events and all-cause mortality. Calciphylaxis is a specific and life-threatening manifestation of vascular calcifications that usually affects individuals with advanced kidney function impairment or those undergoing dialysis. Currently, the treatment of vascular calcification and calciphylaxis in CKD lacks approved treatments and focuses on controlling risk factors...

BACKGROUND: Fabry nephropathy is a consequence of the deposition of globotriaosylceramide, caused by deficient GLA enzyme activity in all types of kidney cells. These deposits are perceived as damage signals leading to activation of inflammation resulting in renal fibrosis. There are few studies related to immunophenotype characterization of the renal infiltrate in kidneys in patients with Fabry disease and its relationship to mechanisms of fibrosis. This work aims to quantify TGF-β1 and active caspase 3 expression and to analyze the profile of cells in inflammatory infiltration in kidney biopsies from Fabry naïve-patients, and to investigate correlations with clinical parameters...

BACKGROUND: Hyponatremia is implicated in pathological bone resorption and has been identified as a risk factor for bone fracture in the general population. However, there are limited data on the association between serum sodium levels and fracture risk in patients undergoing hemodialysis (HD). METHODS: We analyzed a historical cohort of 2220 maintenance HD patients to examine the association between serum sodium levels and the risk of fracture and mortality. We also examined the association between serum sodium levels and osteoporosis, based on metacarpal bone mineral density, in a subcohort of 455 patients with available data...

Autosomal dominant polycystic kidney disease (ADPKD), the most common hereditary kidney disease, accounts for approximately 10% of the patients on kidney transplantation waitlists. High rates of complications including hemorrhage, infections, nephrolithiasis and kidney size-related compressive complaints have been reported among ADPKD patients. Therefore, the need for routine native nephrectomy and timing of such procedure in ADPKD patients being prepared for transplantation are debated. Even though pre-transplant nephrectomy has the potential to provide fewer infectious complications due to lack of immunosuppressive medication use, such procedure has been associated with longer hospital stay, loss of residual kidney function and need for dialysis...

BACKGROUND: Phospholipase A2 receptor (PLA2R)-associated membranous nephropathy accounts for the majority of membranous nephropathy; however, few studies have determined the prognostic impact and clinical application of renal pathologic change on this disease. METHODS: A retrospective cohort study of 262 patients with PLA2R-associated membranous nephropathy was conducted. The total renal chronicity score calculated according to the degree of glomerulosclerosis, interstitial fibrosis, tubular atrophy, and arteriosclerosis was applied to evaluate renal chronicity...

AIM: This study aimed to assess the predictive role of neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, lymphocyte-to-monocyte ratio, and mean platelet volume, on catheter survival in chronic hemodialysis patients, analyzing both infectious and non-infectious complications. METHODS: A retrospective analysis encompassed 1279 tunneled catheter insertion procedures involving 902 patients between March 2014 and October 2018. Patients were categorized into two main groups: (i) initial placement and (ii) exchange...

Cystinuria is an autosomal recessive disorder associated with defective proximal tubular reabsorption of divalent amino acids. It leads to increased cystine, ornithine, lysine, and arginine excretion in the urine. Cystine is insoluble in physiological pH, and cystinuria leads to crystalluria and nephrolithiasis. We present a case of acquired cystinuria in a renal transplant recipient, that is, to the best of our knowledge, the first case of acquired cystinuria ever documented in the literature.

BACKGROUND: In Italy, nephrology residency is available in twenty-one nephrology schools, each with its own strengths and weaknesses. The present study is aimed at exploring the residents' satisfaction with their training programs. METHODS: Between April 20th and May 19th, 2021, a questionnaire on residency satisfaction consisting of 49 items was sent to 586 residents and 175 recently certified specialists (qualified to practice as nephrologists in 2019 and 2020), with a response rate of 81% and 51%, respectively...

Based on the current projection of the general population and the combined increase in end-stage kidney disease with age, the number of elderly donors and recipients is increasing, raising crucial questions about how to minimize the discard rate of organs from elderly donors and improve graft and patient outcomes. In 2002, extended criteria donors were the focus of a meeting in Crystal City (VA, USA), with a goal of maximizing the use of organs from deceased donors. Since then, extended criteria donors have progressively contributed to a large number of transplanted grafts worldwide, posing specific issues for allocation systems, recipient management, and therapeutic approaches...

BACKGROUND: Data on exercise activities in place, and on the interest for developing them in Nephrology Services in Italy is limited. To address this gap, we carried out this cross-sectional study to investigate the status of physical activity and exercise programs available in Italian Nephrology Centres. Additionally, research priorities on this topic were examined. METHODS: We developed a 14-item electronic survey, which consisted of multiple-choice questions covering exercise training programs, physical assessment, barriers to exercise practice and to exercise programs, exercise and physical activity counselling practices, perceived exercise benefits, literature evidence, and research priorities...

BACKGROUND: Kidney supportive care is an interdisciplinary model of person-centred medicine, suitable for patients with advanced Chronic Kidney Disease (CKD) and with End-Stage Kidney Disease (ESKD). There is little information on routine care, and palliative care remains poorly integrated into standard nephrology care. The aim of this study was to describe our experience in integrating a palliative care approach into the nephrology care of advanced chronic and end-stage kidney disease...

Successful induction of remission in anti-glomerular basement membrane (anti-GBM) glomerulonephritis can be obtained by using rituximab as a first-line immunosuppressive agent. We report the case of a 20-year-old male patient with Goodpasture's (anti-GBM) syndrome, with poor prognostic factors at presentation including intra-alveolar hemorrhage and dialysis-dependent rapidly progressive glomerulonephritis. The diagnosis was confirmed on kidney biopsy and serology (anti-GBM antibody titer). Rituximab was used as the first-line immunosuppressive agent in combination with pulse corticosteroids and plasmapheresis, to avoid potential side effects of cyclophosphamide...

BACKGROUND: IgA nephropathy (IgAN) is a common primary glomerular disease. The O-glycosylation status of IgA1 plays a crucial role in disease pathophysiology. The level of poorly-O-galactosylated IgA1, or galactose-deficient IgA1 (Gd-IgA1), has also been identified as a potential biomarker in IgAN. We sought to examine the value of serum Gd-IgA1 as a biomarker in IgAN, by investigating its association with clinical, laboratory, and histopathological features of IgAN. METHODS: The review followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations and was registered in PROSPERO (CRD42021287423)...

INTRODUCTION: Interstitial fibrosis and tubular atrophy are leading causes of renal allograft failure. Shear wave elastography could be a promising noninvasive method for providing information on the state of the kidney, with specific regard to fibrosis but currently available data in the literature are controversial. Our study aimed to analyze the correlation between shear wave elastography and various kidney dysfunction measures. METHODS: This review was registered on PROSPERO (CRD42021283152)...
