Introduction: Macroscopic hematuria (MH) bouts, frequently accompanied by acute kidney injury (AKI-MH) are one of the most common presentations of IgA nephropathy (IgAN) in the elderly. Immunosuppressive therapies are used in clinical practice; however, no studies have analyzed their efficacy on kidney outcomes.

Methods: This is a retrospective, multicenter study of a cohort of patients aged ≥50 years with biopsy-proven IgAN presenting with AKI-MH.

Background And Objective: To describe the clinical characteristics, the reasons for initiating therapy and the effects of treatment in the initial phase of evolocumab availability in the Nephrology Units of Spain.

Material And Methods: Retrospective, observational and multicentric study that included patients initiating treatment with evolocumab (from February 2016 to August 2018), in 15 Nephrology Units in Spain. The demographic and clinical characteristics of the patients, the lipid lowering treatment and the evolution of the lipid profiles between 24 weeks pre-initiation and 12±4 weeks post-initiation of evolocumab were reviewed.

Monoclonal gammopathy of renal significance is a clinical-pathological entity grouping renal disorders secondary to the secretion of a monoclonal immunoglobulin synthesized by a B-cell-derived clone and/or plasma cells in a patient with no diagnostic criteria for multiple myeloma. This term applies to a concept recently introduced owing to the need to differentiate this entity from monoclonal gammopathy of undetermined significance, given the negative prognostic impact of its high morbidity and mortality resulting from both renal and systemic involvement, occasionally even progressing to advanced chronic kidney disease. The renal damage occurs via both direct pathogenic mechanisms, with the deposition of the monoclonal protein in different renal structures, as well as indirect mechanisms, acting as an autoantibody provoking dysregulation of the alternative complement pathway.

Background: The association between cardiac complications, such as heart failure (HF), and chronic kidney disease (CKD) is well known. In this study, we examined the effectiveness and safety of treatment with neprilysin inhibition in patients with advanced chronic kidney disease (stage 3b-4).

Methods: This single-centre, longitudinal, retrospective study of 31 months duration involved consecutive patients with CKD and HF with a reduced ejection fraction (HFrEF) who started treatment with sacubitril/valsartan.

A cyclical corticosteroid-cyclophosphamide regimen is recommended for patients with primary membranous nephropathy at high risk of progression. We hypothesized that sequential therapy with tacrolimus and rituximab is superior to cyclical alternating treatment with corticosteroids and cyclophosphamide in inducing persistent remission in these patients. This was tested in a randomized, open-label controlled trial of 86 patients with primary membranous nephropathy and persistent nephrotic syndrome after six-months observation and assigned 43 each to receive six-month cyclical treatment with corticosteroid and cyclophosphamide or sequential treatment with tacrolimus (full-dose for six months and tapering for another three months) and rituximab (one gram at month six).

Article Synopsis
  • The study investigates the increasing incidence of IgA nephropathy among older adults (aged ≥65) and analyzes various clinical aspects of the disease based on a cohort of 151 patients diagnosed between 1990 and 2015.
  • Researchers observed a significant rise in diagnoses over the years, with common symptoms including asymptomatic urinary issues and acute kidney injury (AKI), particularly related to hematuria.
  • The study found that age, serum creatinine levels, and kidney biopsy findings were linked to worse outcomes, while treatment with specific medications showed potential benefits for survival rates.

Background: Patients starting dialysis treatments are increasingly elderly and with high morbidity and mortality. Survival and factors influencing mortality are discussed.

Methods: We studied 2,601 patients who started hemodialysis in Andalucía (Spain) between 2004 and 2007.

Introduction: Acute renal failure (ARF) occurs in 12%-20% of all multiple myeloma (MM) cases, and the survival of these patients depends on renal function recovery. Renal function is not recovered in 75% of dialysis-dependent patients, and their mean survival with replacement therapy is less than one year. Renal tubular disease is the most frequent cause of renal failure.

Background: Timely referral, preparation and initiation of dialysis remain problematic issues. The purpose of this study is to analyse the effect of chronic renal disease care and education on the mode of dialysis start (planned vs non-planned) and on the modality of renal replacement therapy (RRT).

Methods: A total of 1504 patients from 35 hospitals started RRT in 2003.
