UNLABELLED: (18)F-FDG accumulates in glycolytically active tissues and is known to concentrate in tissues that are rich in activated macrophages. In this study, we tested the hypotheses that human granulocyte-macrophage colony-stimulating factor (GM-CSF), a clinically used cytokine, increases macrophage glycolysis and deoxyglucose uptake in vitro and acutely enhances (18)F-FDG uptake within inflamed tissues such as atherosclerotic plaques in vivo. METHODS: In vitro experiments were conducted on human macrophages whereby inflammatory activation and uptake of radiolabeled 2-deoxyglucose was assessed before and after GM-CSF exposure...

Human intravenous immune globulin (IVIg), a purified IgG fraction composed of ~ 60% IgG1 and obtained from the pooled plasma of thousands of donors, is clinically used for a wide range of diseases. The biological actions of IVIg are incompletely understood and have been attributed both to the polyclonal antibodies therein and also to their IgG (IgG) Fc regions. Recently, we demonstrated that multiple therapeutic human IgG1 antibodies suppress angiogenesis in a target-independent manner via FcγRI, a high-affinity receptor for IgG1...

Assessing the depth of anesthesia and reducing intraoperative awareness has become a focus of much technology development and research in the field of anesthesia. Bispectral index (BIS) is the most widely utilized technology that uses electroencephalogram to provide a measurement of anesthetic depth. There are no definitive guidelines on when BIS should be used. Our aim was to assess actual patterns of intraoperative use of BIS by anesthesia professionals. We retrospectively collected intraoperative data on 55,210 surgical cases at a tertiary care hospital...

While not all multiple sclerosis (MS) relapses require treatment, relapses that are bothersome or that impair function should prompt consideration of timely treatment to restore function and minimize disability. Patients with suspected MS relapses should be evaluated to confirm the diagnosis, exclude other causes of neurological dysfunction, and identify potential triggers for relapse or pseudo-relapse, such as urinary tract infections, fever, or metabolic derangements. The diagnosis of an MS relapse is clinical, but MRI may be useful for confirmation and to evaluate for multifocal disease activity...

This Current perspectives article will review and highlight the importance of accurate diagnosis of patients who have failed to produce specific antibodies to naturally encountered foreign proteins or polysaccharides or after vaccination and the appropriate institution of immunoglobulin replacement therapy. The field of primary immunodeficiency disease (PIDD) has expanded remarkably since the early descriptions 6 decades ago. With greater recognition and advanced cellular and molecular diagnostic technology, new entities and single-gene defects in patients with PIDD are rapidly being defined...

OBJECTIVES: Pruritus may be a significant problem for patients in the postoperative period. There are many options for the treatment of pruritus including intravenous (IV) naloxone. However, it is not clear whether the use of IV naloxone may also affect analgesia or other opioid-related side effects. The authors have performed a systematic review to further examine this issue. METHODS: Systematic literature searches of the National Library of Medicine's PubMed and EMBASE databases were conducted using terms related to postoperative use of IV naloxone...

The incidence and severity of infusion-related adverse events (AEs) after infusions of IGIV-C, 10%, (Gamunex) at 0.14 mL/kg/min versus 0.08 mL/kg/min (standard rate) were compared. Patients with confirmed PID received two infusions 3-4 weeks apart with IGIV-C, 10% 400-600 mg/kg. Patients received their first infusion at 0.08 or 0.14 mL/kg/min and their second infusion 3-4 weeks later at the alternate rate, at an established step-wise rate increase. Ninety-seven of 100 patients remained valid for safety assessment...

RANTES (CC chemokine ligand 5) contributes to airway inflammation through accumulation of eosinophils, but the exact role of RANTES (CCL5) is not defined. C57BL/6 mice, sensitized by injection of ovalbumin (OVA) on Days 1 and 14, were challenged with OVA on Days 28, 29, and 30 (3 challenges, short-term-challenge model) or on Days 28, 29, 30, 36, 40, 44, and 48 (7 challenges, repeated-challenge model) and evaluated 48 h later. Anti-mouse RANTES was given intravenously, and recombinant mouse RANTES or PBS was given intratracheally...

Erwin W Gelfand
The use of immune globulin intravenous (IGIV) as replacement therapy in immunodeficiency disease and as anti-inflammatory or immunomodulatory therapy in a variety of autoimmune and inflammatory diseases has expanded dramatically over the last decade. With this expansion, new challenges and concerns have emerged. As well, new products have been introduced while others have been discontinued. This evolution poses the important issue of product selection, choosing the "right" product for an individual patient...

Use of intravenous immunoglobulin (IVIG) therapy has expanded enormously in the past two to three decades, targeting a large number of autoimmune and inflammatory disorders as well as primary immunodeficiency disease, human immunodeficiency virus, and Kawasaki disease. Increased use, particularly at higher doses and in older patients, has presented certain challenges related to safety and tolerability. All IVIGs are not the same. They differ in manufacturing processes, methods of virus elimination, and final composition...

BACKGROUND: Radiopharmaceutical uptake of [(18)F]2-deoxy-2-glucose (FDG) in brown adipose tissue is noted on 15-20% of positron emission tomography (PET) scans in children and adolescents. One report suggests that moderate-dose oral diazepam can partly or completely block FDG uptake in brown adipose tissue. OBJECTIVE: To determine whether [(18)F]FDG uptake in brown adipose tissue can be adequately blocked by pre-medication other than moderate-dose oral diazepam...

Antibody or humoral immunodeficiencies comprise the largest group of primary immunodeficiency diseases. Since the first description of patients with low gammaglobulin levels more than four decades ago, a great wealth of information has been accumulated. Especially in the last several years, the application of molecular and genetic techniques has unraveled many of these disorders, identifying disorders of B cell development, failure of class switch recombination and abnormalities of specific antibody production...
