https://e-kcj.org Downie et al.1) defined intravenous immunoglobulin (IVIG) resistance in patients with Kawasaki disease (KD) as any patient who receives a second dose of IVIG and had a fever (body temperature [BT] >38.0°C) since finishing the first IVIG dose (2 g/kg). In addition, patients who do not respond to IVIG (BT ≥37.5°C more than 24 hours after the end of IVIG infusion) seem to develop...

OBJECTIVE Varying observations have been made concerning the use of aspirin (ASA) and/or intravenous immunoglobulin (IVIG) in the prevention of coronary artery aneurysm (CAA) in children with Kawasaki disease. A meta-analysis of published articles on the subject was conducted to evaluate the reported efficacy of these therapies. METHODS All published studies in all languages from 1967 through...

BACKGROUND Despite the increasing use of intravenous immunoglobulin (IVIG) in obstetrics, information on its pharmacokinetics and optimal dosing during each trimester pregnancy is lacking. The aim of this study was to characterize IVIG pharmacokinetics in pregnant women with a history of idiopathic secondary recurrent miscarriage or obstetrical antiphospholipid syndrome and to make dosing recom...

Bullous pemphigoid (BP) mainly targets type XVII collagen (COL17). Intravenous immunoglobulin (IVIg) is used to treat numerous autoimmune diseases, including BP. The major mechanism of action for IVIG is thought to be its immunomodulatory effect. However, little is known about the precise mechanisms of IVIg in BP. We investigate the cellular effects of IVIg, toward treatments for BP. Keratinocy...

PROBLEM Recurrent spontaneous abortion associated with immunologic abnormalities has been termed immunologic abortion. Previously we showed that treatment with low-dose intravenous immunoglobulin (IVIG) appears to be beneficial for older women with immunologic abortion. We now report the results of IVIG treatment in a larger group of women with this disorder. METHOD OF STUDY A total of 99 wom...

BACKGROUND Intravenous immunoglobulin (IVIg) therapy has been shown to have therapeutic benefit in more than 50 inflammatory and immune-related diseases; however, the potential benefit of IVIg in cardiovascular disease is more limited, in part because our understanding of the mechanisms underlying the effects of IVIg in innate immunity is incomplete. METHODS AND RESULTS In this study, a syste...

BACKGROUND Intravenous immunoglobulin (IVIG) is the treatment of choice in Kawasaki disease (KD). IVIG is used to prevent cardiovascular complications related to KD. However, a proportion of KD patients have persistent fever after IVIG treatment and are defined as IVIG resistant. METHODS AND RESULTS To develop a risk scoring system based on genetic markers to predict IVIG responsiveness in KD...

We have recently reported that intravenous Ig (IVIg) inhibits uptake of activated C3 fragments onto antibody-sensitized red blood cells (RBCs). To elucidate the mechanism by which IVIg exerts its effect on the complement system, we examined the possible interference with the C4 step of the classical complement cascade. We examined the capacity of autologous serum containing high concentrations ...

Intravenous immunoglobulin G (IVIg) is widely used against a range of clinical symptoms. For its use in immune modulating therapies such as treatment of immune thrombocytopenic purpura high doses of IVIg are required. It has been suggested that only a fraction of IVIg causes this anti immune modulating effect. Recent studies indicated that this fraction is the Fc-sialylated IgG fraction. The ai...

Kawasaki disease (KD) is an acute febrile vasculitic syndrome of early childhood often complicated by coronary artery lesion that drastically reduces the quality of life. The study aimed to identify a reliable marker for predicting nonresponsiveness to the first course of intravenous immunoglobulin (IVIG) in KD patients. A total of 63 patients with KD were enrolled in the study (IVIG response, ...
