The aim of this retrospective study is to evaluate the efficacy and safety of intravenous immune globulin (IVIg) as immunomodulatory treatment in patients with inflammatory myopathies. We analyzed six patients, observed in a single-center from 2004 to 2012, affected by polymyositis (PM), dermatomyositis (DM) or inclusion body myositis (IBM) and treated with IVIg. IVIg has been successfully used...

Intravenous immunoglobulin G (IVIG) is used in the therapy of various autoimmune and inflammatory conditions. The mechanisms by which IVIG exerts anti-inflammatory effects are not completely understood. IVIG interacts with numerous components of the immune system including dendritic cells, macrophages, T and B cells and modulate their functions. Recent studies have reported that heme oxygenase-...

BACKGROUND & OBJECTIVES Tumour necrosis factor-alpha (TNF-alpha) is regarded as one of the immune factors that can induce demyelination of peripheral nerves in patients with Guillian-Barre syndrome (GBS). This present study was undertaken to find out the role of TNF-alpha and soluble TNF receptors in the pathogenesis of GBS; and to study the effect of intravenous immunoglobulin (ivIg) therapy o...

Despite an increasing use of high-dose therapy of i.v. gammaglobulin (IVIg) in the treatment of various T cell- and Ab-mediated inflammatory and autoimmune diseases, comprehension of the mechanisms underlying its therapeutic benefit has remained a major challenge. Particularly, the effect of IVIg in T cell-mediated autoimmune conditions remains unexplored. Using an actively induced experimental...

BACKGROUND The role of intravenous immunoglobulin (IVIG) as an adjunctive treatment for severe sepsis remains controversial. We hypothesized that IVIG could be effective for treating pneumonia patients who have septic shock. METHODS Mechanically ventilated pneumonia patients with septic shock were identified in the nationwide Japanese Diagnosis Procedure Combination inpatient database from 1 ...

BACKGROUND In a recently reported study, low doses of intravenous immunoglobulins (IVIG) were shown to be as effective as high doses in protecting chronic lymphocytic leukemia (CLL) patients against infections, although a control group was not included. With this background we started a crossover study of low-dose IVIG prophylaxis aimed at investigating its superiority over empirical treatment ...

OBJECTIVE The objective of this study is to evaluate the economic benefits of immunoglobulin replacement therapy achieved subcutaneously (subcutaneous immunoglobulin, SCIG) by the rapid push method compared to intravenous infusion therapy (intravenous immunoglobulin, IVIG) in primary immune deficiency (PID) patients from the healthcare system perspective in the context of the adult SCIG home in...

BACKGROUND Genetic variants in the inhibiting FcγRIIB mediate anti-inflammatory responses and influence IVIG refractoriness (IVIG-R). However, these variants are rare in Asian and Hispanic populations so other genes in the pathway could be potentially involved. IVIG is ineffective in mice lacking SIGN-R1, a related molecule to human DC-SIGN. Further, DC-SIGN is a known receptor for sialylated F...

We have recently found that intravenous immunoglobulin (IVIg) prevents deposition of C3 and C4 fragments onto antibody sensitized erythrocytes. To find out if such an effect results from the blockade of the recognition phase of the classical complement cascade, we investigated the ability of human serum containing high concentrations of IVIg to deposit the recognition subunit of the first compl...

Normal immunoglobulin G for therapeutic use (intravenous immunoglobulin [IVIg]) is used in an increasing number of immune-mediated conditions, including acute and chronic/relapsing autoimmune diseases, transplantation, and systemic inflammatory disorders. Several mutually nonexclusive mechanisms of action account for the immunoregulatory effects of IVIg. Although IVIg inhibits T-cell proliferat...
