Potassium Status In Pediatric Chronic Kidney Disease, Katherine L. Kurzinski

Research Days

Watch recording of live presentation.

Background: Potassium trends are well described in adult chronic kidney disease (CKD) and hyperkalemia is known to be associated with increased disease progression, morbidity, and mortality. Large scale studies assessing potassium trends and the prevalence of hyperkalemia in pediatric CKD have not been performed.

Objectives/Goal: We aimed to characterize median serum potassium levels and the prevalence of hyperkalemia for each CKD stage using the CKiD cohort. The relationship of serum potassium and hyperkalemia with patient demographics, CKD etiology (glomerular or non-glomerular), presence of acidosis, and degree of proteinuria was also evaluated.

Methods/Design: Median serum potassium …

Wilms Tumor Presenting With Spontaneous Necrosis And Clostridium Perfringens Co-Infection, Ronald Palmen, Abbey Elsbernd, Kristin Palmen

Research Days

Background: Wilm’s Tumor (WT) is the most common renal malignancy of childhood. The initial presentation of WT may mimic infection or other malignancies with nonspecific symptoms including fever, abdominal/flank pain, or hematuria. This poses a diagnostic challenge for providers, particularly when both infection and malignancy are observed. We describe a case of WT with spontaneous necrosis initially obscured by overlying Clostridium perfringens infection, making diagnosis of the cancer difficult.

Case Description: A previously healthy 5-year-old girl presented to the emergency department with a two-day history of left flank pain and fevers. In the emergency department, she was tachycardic (130 bpm), …
