COVID-19 Infections in Pediatric Renal Transplant Recipients.

Objectives: The new coronavirus SARS-CoV-2 (COVID-19) first appeared in Turkey in March 2020, spread rapidly, and caused many deaths. Although COVID-19 is mostly a respiratory disease, it can cause kidney and multiorgan failure in some cases. We believe that by sharing information about the course and effects of COVID-19 infection in kidney transplant recipients receiving long-term immunosuppressive therapy our understanding will improve.

Cardiac geometry in children receiving chronic peritoneal dialysis: findings from the International Pediatric Peritoneal Dialysis Network (IPPN) registry.

Background And Objectives: Left ventricular hypertrophy (LVH) is an independent risk factor and an intermediate end point of dialysis-associated cardiovascular comorbidity. We utilized a global pediatric registry to assess the prevalence, incidence, and predictors of LVH as well as its evolution in the longitudinal follow-up in dialyzed children.

Design, Setting, Participants, & Measurements: Cross-sectional echocardiographic, clinical, and biochemical data were evaluated in 507 children on peritoneal dialysis (PD), and longitudinal data were evaluated in 128 patients.

Recurrent vasculopathic skin lesions associated with homozygous protein C deficiency.

Symptomatic protein C deficiency is a rare condition. Vasculopathy associated with hypercoagulable state in protein C deficiency has also been reported rarely. We described a boy who was diagnosed as having homozygous protein C deficiency during the neonatal period, when he developed purpura fulminans.
