Disparities in treatment and outcome of kidney replacement therapy in children with comorbidities: an ESPN/ERA Registry study.

Background: Data on comorbidities in children on kidney replacement therapy (KRT) are scarce. Considering their high relevance for prognosis and treatment, this study aims to analyse the prevalence and implications of comorbidities in European children on KRT.

Methods: We included data from patients <20 years of age when commencing KRT from 2007 to 2017 from 22 European countries within the European Society of Paediatric Nephrology/European Renal Association Registry.

Therapeutic Plasma Exchange in Pediatric Renal Transplantation Experience of One Decade and 389 Sessions.

Objective: There are no specific recommendations for therapeutic plasma exchange (TPE) in children after renal transplantation. The purpose of this study was to report the experience with TPE in a pediatric transplant setting.

Materials And Methods: 59 patients (mean age 12.

Eltrombopag (thrombopoietin-receptor agonist) and plasmapheresis as rescue therapy of acute post-renal transplant immune thrombocytopenia in a child with Schimke immuno-osseous dysplasia-case report.

SIOD is rare disorder related to SMARCAL1 or SMARCAL2 gene mutation, including (among other comorbidities) T-cell immunodeficiency, nephrotic syndrome, and renal failure. Up to 22% of primary patients may develop various autoimmune disorders. We report the case of 11-year-old male with SIOD, who presented ITP at 2 years after renal transplantation with decrease in platelet count (from normal) to 56 000/μL and then (gradually) to 2000/μL.

Rituximab is not a "magic drug" in post-transplant recurrence of nephrotic syndrome.

Unlabelled: Pediatric patients with end-stage renal failure due to severe drug-resistant nephrotic syndrome are at risk of rapid recurrence after renal transplantation. Treatment options include plasmapheresis, high-dose of cyclosporine A/methylprednisolone and more recently-rituximab (anti-B CD20 monoclonal depleting antibody). We report five patients with immediate (1-2 days) post-transplant recurrence of nephrotic syndrome, treated with this kind of combined therapy including 2-4 weekly doses of 375 mg/m(2) of rituximab.

Favorable four-yr outcome after renal transplantation in a patient with complement factor H antibody and CFHR1/CFHR3 gene mutation-associated HUS.

Unlabelled: aHUS is a clinical challenge for successful renal transplantation.

Case Report: A 14-yr-old girl lost her kidneys at the age of 7, due to CFH antibodies and CFH-related protein (CFHR1/CFHR3) homozygous deletion-associated aHUS. CFH, CFI, and MCP gene mutations were excluded.
