A 10% liquid immunoglobulin preparation for intravenous use (Privigen®) in paediatric patients with primary immunodeficiencies and hypersensitivity to IVIG.

Abstract：

BACKGROUND:The objective of this study was to evaluate safety and efficacy of Privigen®, a 10% intravenous immunoglobulin (IVIG), in a particular group of paediatric patients (highly sensitive to previous IVIG infusion) affected with Primary Immunodeficiencies (PID). MATERIAL AND METHODS:Patients (n=8) from 3 to 17 years old diagnosed of PID who often suffered from adverse events related to the infusion to previous IVIG were switched to Privigen® in an open protocol. Data were prospectively collected regarding Privigen® administration: infusion, safety and efficacy. In parallel, data on safety and tolerance were retrospectively collected from medical charts regarding the previous 10% IVIG product used. RESULTS:50% of the patients required premedication with previous IVIG. At the end of the study none required premedication with Privigen®. The infusion rate was lower than that recommended by the manufacturer. All patients had suffered through adverse events during previous IVIG infusion being severe in three patients and recurrent in the rest. With Privigen® only three patients suffered from an adverse event (all cases were milder than previous related). Trough levels of IgG remained stable. None suffer from any episode of bacterial infection. CONCLUSION:The present work shows that Privigen® was safe in a group of hypersensitive paediatric patients who did not tolerate the administration of a previous 10% liquid IVIG by using a particular infusion protocol slower than recommended. The number of adverse effects was smaller than published, and all cases were mild. No premedication was needed. Privigen® was also effective in this small group.
