We have shown that intravenous immunoglobulin (IVIG) contains anti-Aβ autoantibodies and IVIG could induce beta amyloid (Aβ) efflux from cerebrospinal fluid (CSF) to blood in both Multiple Sclerosis (MS) and Alzheimer disease (AD) patients. However, the molecular mechanism underlying IVIG-induced Aβ efflux remains unclear. In this study, we used amyloid precursor protein (AβPP) transgenic mice ...

OBJECTIVE To determine whether the serum N-terminal pro-brain natriuretic peptide (NT-proBNP) can be a useful marker not only to identify the patients with Kawasaki disease (KD) who are at a higher risk of developing coronary artery lesions (CAL), and predict resistance to intravenous immunoglobulin (IVIG). STUDY DESIGN We enrolled 80 patients with the acute phase of KD at a single center. Th...

BACKGROUND Controlled trials have found therapeutic plasma exchange (TPE) and intravenous immunoglobulin (IVIg) infusion therapy to be equally efficacious in treating Guillain-Barré syndrome (GBS). Due to increases in the price of IVIg compared to human serum albumin (HSA), used as a replacement fluid in TPE, we examined direct hospital-level expenditures for TPE and IVIg for meaningful cost-di...

OBJECTIVE The objective of the study was to profile leukocyte markers modulated during intravenous immunoglobulin (IVIg) treatment, and to identify markers and immune pathways associated with clinical efficacy of IVIg for chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) with potential for monitoring treatment efficacy. METHODS Response to IVIg treatment in newly diagnosed IVIg...

Intravenous immunoglobulin (IVIG) is widely used in autoimmune neuromuscular diseases whose pathogenesis is undefined. Many different effects of IVIG have been demonstrated in vitro, but few studies actually identify the mechanism(s) most important in vivo. Doses and treatment intervals are generally chosen empirically. Recent studies in Guillain-Barré syndrome and chronic inflammatory demyelin...

The clinical use of intravenous immunoglobulin (IVIg) based on its immunomodulatory and anti-inflammatory potential remains an ongoing challenge. Fcgamma receptor-mediated effects of IVIg, although well elucidated in certain pathologies, cannot entirely account for its proven benefit in several autoimmune disorders mediated by autoreactive T cells. In this study, we show that prophylactic infus...

Although high-dose intravenous immunoglobulin (IVIG) is generally considered a safe medication for various immune-mediated diseases, thrombotic events have been reported as a complication of the therapy. We report a case who developed thrombotic complications after receiving IVIG. A 56-yr-old woman with idiopathic thrombocytopenic purpura received IVIG at a dose of 400 mg/kg/day for five days. ...

Intravenous immunoglobulin (IVIG) is a blood product prepared from the serum of of a thousand or more blood donors. The IVIG that is available contains complete immunoglobulin G( IgG )molecules which has intact Fc-dependent effector functions. The IgG subclasses match those in normal human serum. It is the main treatment for patients with antibody deficiencies. High dose IVIG (hdIVIG), is used ...

INTRODUCTION Guillain-Barré syndrome (GBS) is the most frequent cause of acute flaccid paralysis and, despite treatment, there continues to be an associated mortality and severe disability ranging from 9 to 17%. This article reviews the rationale behind the existing immunotherapy in GBS and discusses the future direction that work in this area should follow. AREAS COVERED The pathogenesis of ...

Guillain-Barré syndrome (GBS) is an acute, autoimmune inflammatory disorder of peripheral nervous system characterized by a severe functional motor weakness. Treatment with intravenous immunoglobulin (IVIg) is one of the approved and preferred therapeutic strategies for GBS. However, the mechanisms underlying the therapeutic benefit with IVIg in GBS are not completely understood. In the present...
