Eventos adversos en 1395 infusiones con diferentes preparados de gammaglobulina intravenosa. / [Adverse events in 1395 infusions with different intravenous gammaglobulin products].

ABSTRACT

The processes of isolation and sterilization of intravenous gamma globulin (IVIG) affect the end product characteristics and, therefore, its tolerability. Different products have different incidences of adverse reactions. The aim of this study was to quantify the immediate adverse events (AE) caused by the different IVIG preparations. We analyzed 1 395 infusions in 28 patients, with a median of 32.5 per subject (range 2-214), using six different IVIG preparations, with an average dose 40.3 ± 8.3 g. One thousand and thirty-one infusions were analyzed retrospectively and 364 prospectively. Patients used a mean of 2.68 ± 1.8 different IVIGs, with a median of 2 (range 1-6) per person. The number of trademarks used was related to the number of infusions received, r = 0.73. AE presented in 24 (2.3
