C3 Glomerulopathy (C3G) and Immune Complex-associated Membranoproliferative Glomerulonephritis (IC-MPGN) are kidney diseases with different causes. C3G results from problems with the alternative complement pathway, while IC-MPGN is linked to the classical complement pathway due to immune complex formation. These conditions have often been grouped as types of membranoproliferative glomerulonephritis (MPGN) based on their appearance under a microscope, leading to confusion about their biology and treatment options.
Certain groups of patients respond better to immunosuppressive and complement-targeted therapies, and their specific characteristics can help predict treatment outcomes. Most existing studies on C3G and IC-MPGN focus on adults and are small in scale.
In this study, the research team aims to identify and characterize children with C3G and IC-MPGN in the PEDSnet database using data science and chart reviews. The long-term goal is to conduct a large study to understand the natural history of these diseases in children, compare clinical outcomes, and identify predictors of how patients respond to treatment.

Vasoactive Selection in Pediatric Septic Shock and the Use of Cardiac Point-of-Care Ultrasound: A Retrospective Registry Analysis Across Multicenter Pediatric Emergency Medicine and Pediatric Critical Care
Pediatric septic shock requires rapid recognition of cardiovascular failure and timely treatment to restore adequate tissue perfusion. Vasoactive medications are central to management, yet considerable uncertainty remains regarding the optimal first‑line agent. Although guidelines recommend tailoring vasoactive choice to a…
