BACKGROUND Despite encouraging reports on the efficacy of intravenous immunoglobulin (IVIg) in antiphospholipid syndrome, the clinical value of this treatment is not well established, and most of the data are based on case reports and small series of patients. OBSERVATION We describe the significant improvement of leg ulcers with IVIg in a 61-year-old female, with diabetes mellitus, venous pe...

Introduction Kawasaki disease (KD) is an acute, self-limited febrile illness that mainly affecting smallto medium-sized vessels and occurs in early childhood. The etiology is currently unknown, however it likely results from an immunologic response triggered by microbial agents, with documented genetic susceptibility. Intravenous administration of immunoglobulin (IVIG) is the gold standard ther...

A 72-year-old man who had been diagnosed with polymyositis (PM) was admitted to our hospital for pneumonia with exacerbation of muscle weakness, elevation of muscle enzymes, and positive MRI findings. The patient had been refractory to cyclosporine A or azathioprine and hoped to avoid administration of high-dose steroids; intravenous immunoglobulin (IVIG) was therefore administered after improv...

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...

The use of intravenous immunoglobulin (IVIg), which is immunoglobulin G pooled from thousands of healthy donors, in the treatment of immunodeficient and autoimmune diseases has grown during the past 2 decades. Although its initial application was largely limited to replacement therapy in hypogammaglobulinemia, IVIg is gaining acceptance as therapy for autoimmune thrombocytopenia purpura, and a ...

Anti-DNA cell-penetrating autoantibodies have been extensively studied in autoimmune but not in normal sera. We investigated herein the presence and properties of cell-penetrating antibodies (CPAbs) in intravenous immunoglobulin (IVIg), a blood product of pooled normal human IgG. IVIg cell penetration was observed into various cell lines, as well as cells from several organs of mice injected in...

Patients with a clinical diagnosis of chronic inflammatory demyelinating polyneuropathy (CIDP) were randomised in a double-blind, placebo-controlled multicentre trial to investigate whether high-dose intravenous immunoglobulin treatment (IVIg) for 5 consecutive days has a beneficial effect. Fifteen patients were randomised to IVIg and 13 to placebo. In the IVIg treatment group 4 patients improv...

Toxic epidermal necrolysis (TEN) is a life-threatening cutaneous reaction to various medications, including antipsychotics and antibiotics. While cephalosporin-induced TEN is very rare, we present a case of cefepime-induced TEN. There are several commonly used therapies for TEN, including immunosuppressive agents and intravenous immunoglobulin (IVIG), but their true efficacy has not been proven...

PURPOSE Intravenous immunoglobulin (IVIG) is the standard treatment for Kawasaki disease (KD). However, there is still no standard treatment for IVIG-resistant KD. This study aimed to evaluate the efficacy of low-dose methotrexate (MTX) as a treatment for IVIG-resistant KD. MATERIALS AND METHODS We retrospectively analyzed 10-year data for patients with IVIG-resistant KD who were administered...

Intravenous immunoglobulin (IVIG) is the treatment of choice in patients with multifocal motor neuropathy with conduction block (MMNCB). Although IVIG is considered generally safe, neutropenia following IVIG infusion has been recognized as a rare hematologic side effect. Herein we report a patient with MMNCB who developed severe neutropenia following IVIG administration. A 41 year old woman pre...
