There are currently two available enzyme replacement therapies for Fabry disease and little information regarding efficacy and safety of switching therapies. Between 2009 and 2012 there was a worldwide shortage of agalsidase beta and patients on that enzyme were switched to agalsidase alfa. This retrospective observational study assessed a 2-year period of efficacy and safety in a population of Fabry patients, in Argentina (30 patients) and Venezuela (3 patients), who switched therapies from algasidase beta to agalsidase alfa...

BACKGROUND: Proenkephalin (PENK) has been suggested as a novel biomarker for kidney function. We investigated the diagnostic and prognostic utility of plasma PENK in comparison with neutrophil gelatinase-associated lipocalin (NGAL) and estimated glomerular filtration rates (eGFR) in septic patients. METHODS: A total of 167 septic patients were enrolled: 99 with sepsis, 37 with septic shock, and 31 with suspected sepsis. PENK and NGAL concentrations were measured and GFR was estimated by using the isotope dilution mass spectrometry traceable-Modification of Diet in Renal Disease (MDRD) Study and three Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations: CKD-EPI(Cr), CDK-EPI(CysC), and CKD-EPI(Cr-CysC)...

Physiological evidence suggests that sleep modulates kidney function. Our objective was to examine the cross-sectional association between kidney function and objectively-estimated habitual sleep duration, quality and timing in a cohort of patients with mild to moderate chronic kidney disease. This study involved two US clinical centers of the Chronic Renal Insufficiency Cohort (CRIC) study, including 432 participants in a CRIC ancillary sleep study. Habitual sleep duration, quality and timing were measured using wrist actigraphy for 5-7 days...

Retroperitoneal fibrosis (RPF) is an uncommon chronic inflammatory disease of the rear abdomen and it is commonly associated with the complication of uni- or bilateral hydronephrosis. Despite the rarity of this disease, multiple publications concerning etiology, diagnosis, therapy monitoring and both medical and surgical therapy have been published in recent years. Recent research has focused on asbestos exposure as a possible risk factor, the meaning of IgG4-associated RPF, measuring disease activity using different radiological and nuclear medicine procedures, and new approaches to medical therapy...

BACKGROUND Precise evaluation of a living donor's renal function is necessary to ensure adequate residual kidney function after donor nephrectomy. Our aim was to evaluate the feasibility of estimating glomerular filtration rate (GFR) using serum cystatin-C prior to kidney transplantation. MATERIAL AND METHODS Using the equations of the Japanese Society of Nephrology, we calculated the GFR using serum creatinine (eGFRcre) and cystatin C levels (eGFRcys) for 83 living kidney donors evaluated between March 2010 and March 2016...

OBJECTIVE: We evaluated the use of nesiritide in children with critical CHD, pulmonary congestion, and inadequate urine output despite undergoing conventional diuretic therapy. DESIGN: We conducted a retrospective analysis of 11 patients with critical CHD, comprising 18 infusions, each of which occurred during separate hospitalisations. Haemodynamic parameters were assessed, and the stage of acute kidney injury was determined before and throughout the duration of therapy using a standardised definition of acute kidney injury - The Kidney Disease: Improving Global Outcomes criteria...

AIM: Sphingosine-1-phosphate (S1P) influences resistance vessel function and is implicated in renal pathological processes. Previous studies revealed that S1P evoked potent vasoconstriction of the preglomerular microvasculature, but the underlying mechanisms remain incompletely defined. We postulated that S1P-mediated preglomerular microvascular vasoconstriction involves activation of voltage-dependent L-type calcium channels (L-VDCC) and the rho/rho kinase pathway. METHODS: Afferent arteriolar reactivity was assessed in vitro using the blood-perfused rat juxtamedullary nephron preparation and diameter was measured during exposure to physiological and pharmacological agents...

The SCHEDULE trial was a 12-month, randomized, open-label, parallel-group trial that compared everolimus (EVR; n=56) to conventional CsA (n=59) immunosuppression. Previously, we reported that EVR outperformed CsA in improving renal function and coronary artery vasculopathy, despite a higher rejection rate with EVR. The present study aimed to compare the effects of these treatments on quality of life (QoL). Within 5 postoperative days, patients (mean age 50±13 years, 27% women) were randomized to EVR or a standard CsA dosage (CsA group)...

AIMS: It is unclear whether distinct pathophysiological processes are present among patients with acute heart failure (AHF), with and without diabetes. Network analysis of biomarkers may identify correlative associations that reflect different pathophysiological pathways. METHODS AND RESULTS: We analysed a panel of 48 circulating biomarkers measured within 24 h of admission for AHF in a subset of patients enrolled in the PROTECT trial. In patients with and without diabetes, we performed a network analysis to identify correlations between measured biomarkers...

BACKGROUND: Kidney donor outcomes are gaining attention, particularly as donor eligibility criteria continue to expand. Kidney size, a useful predictor of recipient kidney function, also likely correlates with donor outcomes. Although donor evaluation includes donor kidney size measurements, the association between kidney size and outcomes are poorly defined. METHODS: We examined the relationship between kidney size (body surface area-adjusted total volume, cortical volume and length) and renal outcomes (post-operative recovery and longer-term kidney function) among 85 kidney donors using general linear models and time-to-chronic kidney disease data...

Fatigue is a common and debilitating symptom, affecting 42-89% of end-stage kidney disease patients, persisting even in pre-dialysis care and stable kidney transplantation, with huge repercussions on functioning, quality of life and patient outcomes. This paper presents a critical review of current evidence for the role of psychological factors in renal fatigue. To date, research has concentrated primarily on the contribution of depression, anxiety and subjective sleep quality to the experience of fatigue. These factors display consistent and strong associations with fatigue, above and beyond the role of demographic and clinical factors...

BACKGROUND: Considering long-term changes in renal sodium handling and blood pressure in maternal protein-restricted (LP) offspring, we assumed that the development of LP hypertension results from abnormal dorsal root ganglia (DRG) neurokinin expression associated with impaired responsiveness of renal sensory receptors, promoting a reduced urinary excretion of sodium. The present study investigates whether increased blood pressure in protein-restricted offspring would be associated with changes in the DRG cells and in renal pelvic wall expression of NK1R, SP and CGRP when compared to NP offspring...

N-terminal propeptide of type I procollagen and C-terminal telopeptide of type I collagen are the reference standards for bone turnover markers for monitoring osteoporosis treatment. We provide recommendations for standardized sample handling and encompassing aspects of preanalytical variability to improve the reproductibility of their measurements, their reliability, and clinical interpretation. The International Osteoporosis Foundation and International Federation of Clinical Chemistry bone turnover marker standards working group have identified N-terminal propeptide of type I procollagen (PINP) and C-terminal telopeptide of type I collagen (CTX-I) in the blood to be the international reference standards for bone turnover markers for the prediction of fracture risk and monitoring of osteoporosis treatment...

Atorvastatin and ticagrelor combination is a widely accepted therapy for secondary prevention of ischaemic heart disease. However, rhabdomyolysis is a well-known rare side effect of statins which should be considered when treatments are combined with cytochrome P450 3A4 enzyme inhibitors. We report a case of atorvastatin and ticagrelor associated severe rhabdomyolysis that progressed to multiorgan failure requiring renal replacement therapy, inotropes, intubation, and mechanical ventilation. Despite withdrawal of the precipitating cause and the supportive measures including renal replacement therapy, creatinine kinase increased due to ongoing rhabdomyolysis rapidly progressing to upper and lower limbs weakness...

Type II Bartter syndrome is caused by mutations in the Renal Outer Medullary Potassium (ROMK) channel but the molecular mechanisms underlying this disease are poorly defined. To rapidly screen for ROMK function, we developed a yeast expression system and discovered that yeast cells lacking endogenous potassium channels could be rescued by WT ROMK but not by ROMK proteins containing one of four Bartter mutations. We also found that the mutant proteins were significantly less stable than WT ROMK. However, their degradation was slowed in the presence of a proteasome inhibitor or when yeast cells contained mutations in the CDC48 or SSA1 gene, which is required for endoplasmic reticulum (ER)-associated degradation (ERAD)...

Allogeneic hematopoietic cell transplantation (HCT) is curative in patients with β-thalassemia major. However, the majority of reports on HCT outcomes lack long-term follow-up data with the exception of single center reports. An international multicenter retrospective data collection and analysis was conducted in 176 β-Thalassemia patients who were 1 year or beyond after first HCT to evaluate follow up methods and outcomes at 7 centers- Median age at HCT was 5.5 years (range, 0.6- 18.5) and median follow-up was 7 years (range, 1-20)...

Renal involvement in hepatitis B occurs in various spectrums and its knowledge is important for clinicians in management of patients. The renal diseases most commonly associated with hepatitis B virus (HBV) infection include membranous nephropathy, membranoproliferative glomerulonephritis, and Polyarteritis nodosa. The widespread use of hepatitis B vaccination has decreased the incidence of HBV-related renal diseases. The incidence of HBV infection in dialysis patients has significantly decreased over the past few decades due to screening of blood products for hepatitis B surface antigen (HBsAg) and hepatitis B core antibody, implementation of infection control measures and hepatitis B vaccination...

BACKGROUND: Podocyturia may determine the evolution to podocytopenia, glomerulosclerosis, and renal failure. According to the Oxford classification of IgA nephropathy (IgAN), the S1 lesion describes glomerulosclerosis. Urokinase-type plasminogen activator receptor (uPAR) participates in podocyte attachment, while CD80 increases in glomerulosclerosis. We measured uPAR-positive urinary podocytes and urinary CD80 (uCD80) in controls and in IgAN subjects with M1E0S0T0 and M1E0S1T0 Oxford scores to assess a potential association between podocyturia, inflammation, and glomerulosclerosis...
