Abstract
BACKGROUND: Adverse reactions to intravenous immunoglobulins (IVIG) are divided by organ system involved, or by timing of onset-immediate which occur during infusion usually rate-related, true IgE-mediated anaphylaxis and delayed reaction which occur hours to days after the infusion. AIM: To describe the adverse events of patients given IVIG infusions. METHODS: Total number of patients receiving IVIG was 41 with 25 males (60.97%) and 16 females (39.02%), age 2 months-35 years. A total number of infusions was 1350. RESULTS: Total number of adverse reactions 15, 14 patients with immediate-type and 1 with delayed type. Total percentage of adverse reactions in a given sample was 1.1% of all IVIG infusions. Fever was the most common immediate type of reaction occurring in 11 patients (78.57%) followed by acrocyanosis 10 patients (71.42%), skin rash 9 patients (64.28%) and headache 8 patients (57.14). Delayed-type of reactions (like fever, headache and vomiting) was present in one patient. Majority of the adverse effects occurred at the infusion rate higher than 1, 5 ml/kg/hour, which is still within recommended speed. CONCLUSION: About 1.1% of IVG infusions where with adverse events. Most common manifestations where: fever, acrocyanosis, skin rash and headache, which occurred 1-6 hours from the beginning of the infusion. The occurrence of adverse reactions to IVIG was related to the infusion rates in a fashion that faster infusion rate gives more reactions. Adverse reactions were managed by reduction of the infusion rate and administration of medications such as paracetamol, antihistamines and steroids.
