Hypocomplementemic Atypical IgA Vasculitis: A Case Report.

IgA vasculitis (IgAV, also known as Henoch-Schönlein purpura or HSP) is a vasculitis of small vessels involving multiple organs, particularly of the joints, gastrointestinal tract, skin, and kidneys. Growing laboratory evidence has shown that complement plays a key role in the pathogenesis of IgAV, although direct evidence of this association in patients is lacking. We report a child with IgAV associated with clinical features of hypertension, nephrotic range proteinuria, acute kidney injury, and low serum C3, with histopathologic findings on renal biopsy of membranoproliferative glomerulonephritis with C3 and IgA co-dominance, and extensive complement derangements.

Telehealth survey of providers and caregivers of children on peritoneal dialysis during the COVID-19 pandemic.

Background: There has been growing support for the adoption of telehealth (TH) services in pediatric populations. Children on chronic peritoneal dialysis (PD) represent a vulnerable population that could benefit from increased use of TH. The COVID-19 pandemic prompted rapid adoption of TH services in the population among pediatric centers participating in The Children's Hospital Association's Standardizing Care to Improve Outcomes in Pediatric ESKD (SCOPE) Collaborative.

Dose of dialysis based on body surface area is markedly less in younger children than in older adolescents.

Unlabelled: BACKGROUND AND OBSERVATIONS: The current denominator for dosing dialysis is the urea distribution volume (V). Normalizing Kt/V to body surface area (S) has been proposed, but the implications of doing this in children have not been examined.

Design, Setting, Participants, & Measurements: Dialysis dose given to children and adolescents was calculated in terms of conventional V-based scaling and surface-area-normalized standard Kt/V (SAN-stdKt/V) calculated as stdKt/V x (Vant/S)/17.
