Abstract

Immunoglobulin infusion (IVIG) is one of the first line therapy in Guillain Barre Syndrome (GBS). Several medical complications are associated with GBS (pneumonia, sepsis, deep vein thrombosis, dysautonomy). Acute kidney injury (AKI) is an uncommon complication during IVIG infusion. Several risk factors were associated with AKI during IVIG. These are an older age, previous renal disease, concomitant use of nephrotoxic agents, diabetes mellitus, hypovolemia, sepsis or using of IVIG that contained in its preparation sucrose or mannitol as stabilizers to avoid precipitation and aggregation. Infusion rate and total dose play a determinant role. The most important pathophysiological mechanism of AKI are the osmotic stress applied to the epithelium of proximal tubules and glomeruli. The osmotic overload is principally generated by IVIG stabilizers (sucrose). In general, AKI is reversible but approximately 30% hemodialysis is necessary. It is essential to respect doses, infusion rates and closely monitoring renal function parameters during IVIG infusion.
