BACKGROUND AND OBJECTIVES Intravenous Ig (IVIG) is used in renal transplantation for desensitization and treatment of antibody-mediated rejection (AMR). The infusion of high-dose IVIG is generally well tolerated, but there are reports of hemolytic anemia induced by anti-blood group antibodies present in IVIG. Here, we report our experience with IVIG-induced hemolytic anemia (IH) in ESRD patient...

The effect of high dose intravenous immunoglobulin (IVIg) treatment was studied in six patients with multifocal motor neuropathy (MMN). All patients responded to treatment (0.4 g/kg for five consecutive days) in an open trial. The effect of IVIg treatment was confirmed for each patient in a single patient, double blind, placebo controlled trial. Four patients received two IVIg treatments and tw...

Although the mechanism of action of intravenous immunoglobulin (IVIg) in treating antibody-dependent thrombocytopenia remains unclear, most studies have suggested that IVIg blocks the function of Fc receptors in the reticuloendothelial system (RES) and/or the protective effect may be due to the presence of variable region-reactive (anti-idiotype) antibodies within IVIg. We evaluated the effect ...

Intravenous immunoglobulin (IVIg) has been shown to be effective for a variety of autoimmune diseases. Despite its widespread use and therapeutic success, the precise mechanisms for the anti-inflammatory therapeutic effects of IVIg are not well understood. In particular, few reports have examined the mechanism of IVIg on regulatory T cells (Treg: CD4(+)CD25(+)FoxP3(+) T cells). In the present s...

INTRODUCTION Intravenous immunoglobulin (IVIg) is an immune thrombocytopenia (ITP) therapy, which is associated with toxicities, limited availability, increasing utilization, and high cost. This study aimed to assess short- and long-term IVIg utilization in patients with ITP at two tertiary care centers in Ontario, Canada, to determine the proportion of IVIg used in ITP compared with all usage,...

BACKGROUND AND OBJECTIVES The prevalence of incomplete Kawasaki disease (iKD) is progressively increasing. We aimed to retrospectively investigate the predictors of intravenous immunoglobulin (IVIG) resistance in iKD patients and compare them with those of IVIG resistance in complete Kawasaki disease (cKD) patients. We also compared the prognosis of coronary artery lesions (CALs) between the IV...

Intravenous immunoglobulin (IVIg) is an effective treatment against immune thrombocytopenia (ITP). Previous studies suggested that IVIg exerts this ameliorative role through 2 different leukocyte subsets. Dendritic cells (DCs) modulate the immunosuppression in an adoptive cell transfer model, and phagocytes up-regulate their inhibitory IgG Fc receptors (FcγR)IIB expression and thereby ameliorat...
