This report presents a pediatric patient with neutropenic septic shock and multiorgan failure (MOF) with a 95% chance of death and the availability of a therapeutic device with a completely new approach to treat sepsis. This device, called the selective cytopheretic device (SCD), is a first-in-class autologous immune cell directed therapy. The SCD, when integrated into an extracorporeal blood circuit, has been shown to bind activated neutrophils and monocytes. With a simple pharmacologic maneuver within the device, the bound cells in real time are immunomodulated from a highly pro-inflammatory state to a less inflammatory phenotype. These transformed cells are then released back into the systemic circulation thereby tempering the systemic hyperinflammatory disorder. Since this cell directed therapy focuses on neutrophils, the processing of these cells in a neutropenic state may be a substantive risk resulting in further immunosuppression. On the other hand, the immunomodulation of the circulating neutrophils and monocytes, although sparse, may be beneficial to disrupt the dysregulated inflammatory state responsible for ongoing tissue damage and organ dysfunction. Prior clinical SCD trials excluded patients with neutropenia so that no prior clinical experience was available to make a difficult decision.

This pathway is dependent on multi-ligand receptors: megalin and cubilin. Abnormalities in genes associated with endocytosis in the proximal tubule can lead to tubular proteinuria, where the urine contains albumin and low-molecular-weight proteins. Dent disease is a hereditary X-linked disorder characterized by low-molecular-weight proteinuria, hypercalciuria, nephrocalcinosis, nephrolithiasis, and progressive kidney dysfunction, often leading to CKD stage 5. CLCN5 is the gene responsible for Dent disease-1 and encodes the voltage-gated chloride channel ClC-5. Meanwhile, OCRL is the causative gene of Dent disease-2 and encodes phosphatidylinositol 4,5-bisphosphate 5-phosphatase, and its variants are also associated with Lowe syndrome. ClC-5 and OCRL are essential to the endocytic machinery, and their loss affects endosomal acidification and trafficking, resulting in disruption of megalin and cubilin recycling. CUBN, which encodes cubilin, was originally identified as the causative gene of Imerslund-Gräsbeck syndrome, a disorder of megaloblastic anemia associated with proteinuria. However, recently, a biallelic C-terminal variant of CUBN was shown to be responsible for isolated proteinuria without kidney dysfunction. This proteinuria is recognized as a new disease concept called chronic benign proteinuria (proteinuria, chronic benign: PROCHOB), which contradicts the common belief that proteinuria is harmful and ultimately leads to kidney damage.
