Intravenous immunoglobulin (IVIG) for the treatment of HGG post-lung transplant is not well studied with conflicting evidence regarding efficacy. This single-center, retrospective cohort study analyzed adult lung transplant recipients with HGG receiving ≥1 dose of IVIG 0.3-0.5 g/kg. Resolution of HGG (IgG > 600 mg/dL within 30 days of IVIG) was evaluated for optimal dose and duration of IVIG therapy. Incidence of infection, patient survival, rejection, and chronic lung allograft dysfunction-free survival at 1 year were compared between resolved and persistent HGG. Results demonstrated majority of patients 46/58 (79.3%) achieved HGG resolution.
