Is There a Role for IgA/C3 Ratio in IgA Nephropathy Prognosis? An Outcome Analysis on An European Population.

Introduction: Serum immunoglobulin A (IgA)/C3 ratio has been reported as a predictor of histological lesions and prognosis in asian patients with IgA nephropathy (IgAN). Since its validity in other populations is unclear, we aimed to evaluate the relationship between IgA/C3 ratio and renal outcome in Caucasian European patients with biopsy-proven IgAN.

Methods: We conducted a retrospective, observational study on 95 patients with primary IgAN patients diagnosed between 2010 to 2017 (70% male, age 41 (34 to 49) years, eGFR 39.

Non-diabetic glomerular lesions in diabetic kidney disease: clinical predictors and outcome in an Eastern European cohort.

Purpose: Since patients' prognosis depends on the lesions identified by kidney biopsy (KB), we aimed to evaluate predictors of non-diabetic kidney disease (NDKD) in diabetic subjects and to assess their kidney outcome as compared to diabetic nephropathy (DN).

Methods: 180 adults diagnosed by KB with DN (n = 120) or NDKD (n = 60), over a 10 year time-span, were retrospectively included and followed for a mean of 48.1 (95% CI 43.

We report a patient with IgM-predominant type I cryoglobulinemia (CG), who presented to our nephrology department with acute kidney injury. He was previously diagnosed with sensorimotor neuropathy, which was in remission with maintenance dose of corticosteroids.

A Case Report of Generalized Pustular Psoriasis Associated With IgA Nephropathy.

Psoriasis vulgaris is a complex immune-mediated disorder that manifests as a chronic skin disorder, characterized by well-circumscribed inflammatory, erythematous plaques. In this case report, we present a patient with generalized pustular psoriasis (GPP) who presented to the nephrology department with rapidly progressive decline in renal function. The diagnosis of GPP was made a month ago, secondary to a coagulase-negative staphylococcal superinfection.

Results from the ERA-EDTA Registry indicate a high mortality due to COVID-19 in dialysis patients and kidney transplant recipients across Europe.

The aim of this study was to investigate 28-day mortality after COVID-19 diagnosis in the European kidney replacement therapy population. In addition, we determined the role of patient characteristics, treatment factors, and country on mortality risk with the use of ERA-EDTA Registry data on patients receiving kidney replacement therapy in Europe from February 1, 2020, to April 30, 2020. Additional data on all patients with a diagnosis of COVID-19 were collected from 7 European countries encompassing 4298 patients.

Kidney Involvement in Hypocomplementemic Urticarial Vasculitis Syndrome-A Case-Based Review.

Hypocomplementemic urticarial vasculitis syndrome (HUVS), or McDuffie syndrome, is a rare small vessel vasculitis associated with urticaria, hypocomplementemia and positivity of anti-C1q antibodies. In rare cases, HUVS can manifest as an immune-complex mediated glomerulonephritis with a membranoproliferative pattern of injury. Due to the rarity of this disorder, little is known about the clinical manifestation, pathogenesis, treatment response and outcome of such patients.

Towards a simplified renal histopathological prognostic score in glomerular nephropathies.

Aims: An important role of native kidney biopsy evaluation is to predict renal prognosis. We aimed to develop a simplified chronicity score based solely on pathological features that are easily recognisable and can be found in all glomerular nephropathies (GN). In this retrospective study, observational cohort study we included 625 patients with GN diagnosis after native kidney biopsy in a tertiary unit between 1 January 2010 and 31 December 2015.

Has The Time Arrived to Refine The Indications of Immunosuppressive Therapy and Prognosis in IgA Nephropathy?

Immunoglobulin A nephropathy (IgAN) is the most frequent glomerular disease worldwide and a leading cause of end-stage renal disease. Particularly challenging to the clinician is the early identification of patients at high risk of progression, an estimation of the decline in renal function, and the selection of only those that would benefit from additional immunosuppressive therapies. Nevertheless, the pathway to a better prognostication and to the development of targeted therapies in IgAN has been paved by recent understanding of the genetic and molecular basis of this disease.

"Associated" or "Secondary" IgA nephropathy? An outcome analysis.

Background: Whether differences in outcome between primary (pIgAN) and secondary IgA nephropathy (sIgAN) exist is uncertain.

Methods: We conducted a retrospective, observational study that included all histologically diagnosed IgAN patients between 2010-2017 (N = 306), 248 with pIgAN and 58 with sIgAN. To obtain samples with similar risk of progression, sIgAN patients were grouped as liver disease and autoimmune/viral disease and propensity score matched to corresponding pIgAN samples.

Histologic predictors of renal outcome in diabetic nephropathy: Beyond renal pathology society classification.

The prognostic utility of histologic features in patients with diabetic nephropathy (DN) classified according to the Renal Pathology Society (RPS) classification is controversial. Therefore, we aimed to evaluate the relationship between histologic changes and renal outcome in DN patients.We examined the renal outcome at November 30, 2017 of 74 adult patients (median age of 54.

Renal anemia and hydration status in non-dialysis chronic kidney disease: Is there a link?

Anemia, a common feature in chronic kidney disease (CKD), has multiple contributors to its pathogenesis. Besides the well recognized erythropoietin and iron deficiencies, hydration status might be involved. To assess the prevalence and correlations of anemia, iron deficiency and overhydration in patients with stage 2 to 5 CKD.

Metabolic Acidosis of Chronic Kidney Disease and Cardiovascular Disorders.

The burden of chronic diseases, which include both cardiovascular diseases (CVD) and chronic kidney disease (CKD), is constantly growing worldwide. Moreover, bidirectional links between kidney and heart disorders are commonly recognized and the pathogenesis of these interactions is a matter of current interest in medicine. One remarkable aspect, extensively showed by epidemiological studies, is the very high prevalence of CVD in patients with CKD, up to thirty times higher than in the general population.

Recovery of Kidney Function in Children Treated with Maintenance Dialysis.

Background And Objectives: Data on recovery of kidney function in pediatric patients with presumed ESKD are scarce. We examined the occurrence of recovery of kidney function and its determinants in a large cohort of pediatric patients on maintenance dialysis in Europe.

Design, Setting, Participants, & Measurements: Data for 6574 patients from 36 European countries commencing dialysis at an age below 15 years, between 1990 and 2014 were extracted from the European Society for Pediatric Nephrology/European Renal Association-European Dialysis and Transplant Association Registry.

Histological predictors of renal outcome in lupus nephritis: the importance of tubulointerstitial lesions and scoring of glomerular lesions.

Introduction Lupus nephritis (LN) affects nearly 60% of patients with systemic lupus erythematosus and up to 30% of them will progress to end-stage renal disease (ESRD), despite receiving aggressive immunosuppressive therapy. The prognostic value of ISN/RPS classification is controversial. Therefore, we aimed to identify clinical and pathological predictors of outcome in LN patients independent of this classification.

Validation study of Oxford Classification of IgA Nephropathy: the significance of extracapillary hypercellularity and mesangial IgG immunostaining.

The Oxford classification (OC) of IgA Nephropathy (IgAN) identified mesangial hypercellularity (M), endocapillary hypercellularity (E), segmental glomerulosclerosis (S), and tubular atrophy/interstitial fibrosis (T) as predictors of outcome. We aimed to validate the OC and to investigate the clinical significance of extracapillary hypercellularity and IgG immunostaining.

Ketoanalogue-Supplemented Vegetarian Very Low-Protein Diet and CKD Progression.

Dietary protein restriction may improve determinants of CKD progression. However, the extent of improvement and effect of ketoanalogue supplementation are unclear. We conducted a prospective, randomized, controlled trial of safety and efficacy of ketoanalogue-supplemented vegetarian very low-protein diet (KD) compared with conventional low-protein diet (LPD).
