Resumen

Secondary hypogammaglobulinemia (HGG) from immunosuppression therapy in lung transplant recipients has been associated with increased mortality, morbidity and higher risk of infection. 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. Severe HGG (IgG < 400 mg/dL) was significantly associated with persistent HGG (50.5% vs 15.2%, p = 0.02), with comparable cumulative IVIG dose and duration between both groups (p = 0.96 and p = 0.39, respectively). No other variables correlated with HGG resolution. Overall infection rates were similar between groups (69.6% vs 58.3%, p = 0.50), suggesting HGG resolution did not correlate with incidence of infection. Lastly, use of IVIG for the treatment of HGG appears to be safe with minimal incidence of thrombosis found within each group.
