- W2123199265 abstract "In Brief Background After lung transplantation (LT), immunoglobulin (Ig) G plasma concentrations <6 g/L are common and correlate with an increased risk of chronic lung allograft dysfunction (CLAD) and a poorer survival. Methods We conducted an open substitution intervention with nonspecific intravenous Ig (IVIg), in all patients with IgG plasma less than 6 g/L post-LT in 54 of 84 consecutive recipients since 1998 who survived more than 3 months. Pre-LT and post-LT events were retrospectively analyzed. Results Both substituted and nonsubstituted groups demonstrated similar donor or recipient characteristics and events over a median follow-up of 2.8 years (Q1-Q3, 1.4-5.7], except for initial diagnosis with more chronic obstructive pulmonary disease patients and less cases of pulmonary arterial hypertension in NS group. Intravenous Ig substitution started 3.5 months (0.5-9.4) after transplantation and lasted 4.5 months after (1.0-17.7), mean cumulative dose was 52.8 ± 47.7 g. In multivariate Cox regression model, hypogammaglobulinemic patients who were substituted with IVIg had actually a 5-year survival (hazard ratio, 0.63; 95% confidence interval, 0.26-1.49; P = 0.29) and CLAD-free 5-year survival (hazard ratio, 0.51; 95% confidence interval, 0.15-1.67; P = 0.27) really close to nonhypogammaglobulinemic and nonsubstituted patients. Complementary analysis using propensity score and time-dependent analysis showed that survival and CLAD-free survival were not different in both groups. Conclusion Intravenous Ig post-LT achieved similar survival and CLAD-free survival in recipients with hypogammaglobulinemia as compared to those with normal IgG plasmatic rate. A randomized control trial is required to confirm benefic effects of IVIg and disentangle mechanisms, including protection from infections, acute cellular and humoral rejections in patients with hypogammaglobulinemia after LT. This retrospective single-center study shows that intravenous immunoglobulin administration to hypogammaglobulinemic lung allograft recipients may result in improved survival and lung function." @default.
