OBJECTIVES Clinical data are lacking on optimal levels of specific antipneumococcal antibodies (PnPsAbs) in patients with primary immunodeficiency (PID) receiving intravenous immunoglobulin (IVIG) replacement. Objectives were to conduct a prospective multicenter study providing data on total immunoglobulin G (IgG) and peak/trough levels of PnPsAbs specifically targeting the 16 most prevalent pn...

BACKGROUND The natural history of coronary artery aneurysms (CAA) after intravenous immunoglobulin (IVIG) treatment in the United States is not well described. We describe the natural history of CAA in US Kawasaki disease (KD) patients and identify factors associated with major adverse cardiac events (MACE) and CAA regression. METHODS AND RESULTS We evaluated all KD patients with CAA at 2 cen...

An 7-year-old girl with ocular myasthenia gravis (MG) refractory to prednisolone and anticholinesterase compounds was treated with high-dose intravenous immunoglobulin (IVIg). Ocular symptoms disappeared rapidly by the administration of IVIg 300 mg/kg/day for five consecutive days. Booster infusions of IVIg at an interval of 2 weeks appeared to be effective in maintaining a remission at least a...

Methods Mice were sensitized (i.n.) with OVA and then received IVIg or sialic acid enriched IVIg (SA-IVIg) fragments (i.p.), and then underwent challenge (i.n.). The induction of CD4CD25Foxp3Treg was determined by flowcytometry. AHR was measured, using a flexiVent small animal ventilator. Phenotypic properties of dendritic cells (DC) from various experimental groups were assessed by flow-cytome...

Intravenous immunoglobulin (IVIG) is used in the treatment of neuropathy. This case report presents, for the first time, a patient with severe periodontal destruction after chronic therapy with IVIG. The patient reported having extracted his maxillary anterior teeth himself due to high mobility. Clinical examination and radiographic images show a generalized and severe periodontitis. No signifi...

Amyopathic dermatomyositis (ADM) is a rare subtype of dermatomyositis which is often recalcitrant to immune suppressing treatments. Intravenous immunoglobulin (IVIG) has been used in the treatment of refractory dermatomyositis. We present two patients with severe ADM, who were treated with IVIG at 2 g/kg every four weeks. Both patients had a successful response and were able to taper the dosage...

We treated five consecutive patients with multifocal motor neuropathy (MMN) with high-dose intravenous immunoglobulin (IVIg). Four patients had increased levels of anti-asialo-GM1 IgM and two of anti-GM1 IgM as well; one patient had no reactivity. We treated them twice with 0.4 g/kg IVIg for 5 consecutive days at a 2-month interval, followed by maintenance infusions up to 6 to 12 months. All pa...

BACKGROUND Intravenous immunoglobulin (IVIG) is commonly used to improve the immunomodulatory effects, although its regulatory effect on premature Treg cells is unclear. The purpose of this study is to study the effect of high dose of IVIG (HD-IVIG) on Treg cells expression and cytokine profile in premature birth. METHODS Fifty-two premature infants were enrolled in this study and thirty-one ...

Several clinical studies done with intravenous immunoglobulin (IVIg)-treated autoimmune patients as well as several in vitro studies have revealed that IVIg can reduce polyclonal T-cell activation and modify their cytokine secretion pattern. However, their effect on (auto)antigen-specific T-cell responses has never been addressed directly. In the present work, we used an in vivo model of induct...

In patients with hypogammaglobulinemia secondary to chronic lymphocytic leukemia (CLL) or multiple myeloma (MM), intravenous immune globulin (IVIg) may be administered to reduce the risk of infection. Since 2013, IVIg products have carried a boxed safety warning about the risk of thromboembolic events (TEEs), with TEEs reported in 0.5% to 15% of patients treated with IVIg. In this retrospective...
