Subcutaneous Immunoglobulin 16.5% (Cutaquig®) in Primary Immunodeficiency Disease: Safety, Tolerability, Efficacy, and Patient Experience with Enhanced Infusion Regimens.

Purpose: To achieve reductions in infusion time, infusion sites, and frequency, a prospective, open-label, multicenter, Phase 3 study evaluated the safety, efficacy, and tolerability of subcutaneous immunoglobulin (SCIG) 16.5% (Cutaquig®, Octapharma) at enhanced infusion regimens.

Methods: Three separate cohorts received SCIG 16.

Choline supplementation attenuates experimental sepsis-associated acute kidney injury.

Acute kidney injury (AKI) is common in critically ill patients, and sepsis is its leading cause. Sepsis-associated AKI (SA-AKI) causes greater morbidity and mortality than other AKI etiologies, yet the underlying mechanisms are incompletely understood. Metabolomic technologies can characterize cellular energy derangements, but few discovery analyses have evaluated the metabolomic profile of SA-AKI.

NMR-based serum and urine metabolomic profile reveals suppression of mitochondrial pathways in experimental sepsis-associated acute kidney injury.

Sepsis-associated acute kidney injury (SA-AKI) is a significant problem in the critically ill that causes increased death. Emerging understanding of this disease implicates metabolic dysfunction in its pathophysiology. This study sought to identify specific metabolic pathways amenable to potential therapeutic intervention.

Initiation of immunoglobulin therapy by subcutaneous administration in immunodeficiency patients naive to replacement therapy.

Background: Patients with immunodeficiency diseases require lifelong treatment with immunoglobulin (Ig), yet few studies have vetted dosing strategies and effectiveness of Ig in older patient populations. Patients requiring subcutaneous (SC) Ig (SCIG) typically start with intravenous dosing before transitioning to SCIG weekly maintenance. In this retrospective review, we investigated an alternate strategy with higher initial SC doses among an older patient population with antibody deficiency syndromes.
