IMMUNISATION OF CHILDREN WITH CONGENITAL HEART DEFECTS – CLINICAL AND CRITICAL OVERVIEW
Matej Katavić, Daniel Dilber
Numeruous scientific articles indicate the benefit of immunisation when dealing with children with congenital heart defects. High possibility of gaining infections can be related to compromised cardiopulmonary status, changed pressures in pulmonary circulation (including pulmonary hypertension) as well as ventilation-perfusion mismatch. Many children with heart anomalies within heterotaxy syndrome have functional hyposplenism with high susceptibilty to infections. Children with chromosomopathies and many other syndromes have a high frequency of immunodeficiency states of various intensity, alongside hemodynamically significant, often complex heart defects and numerous anomalies of other organs. Cardiopulmonary bypass and ECMO device are inevitably used for operative corrections and palliative procedures, however, main issue is their tendency to decrease the circulating antibodies that have occurred during active immunisation, thereby compromising the acquired immune system. Protecting such patients by systematic immunisation of children and their family members should be the main interest of scientific community. This paper gives a systematic overview of the above mentioned controversy.
