TL;DR: Subgroup analyses suggest the risk may be greater in African Americans compared with Caucasian subjects and whether this risk is due to factors including but not limited to a physiologic treatment effect, genetic factors, or patient behaviors leading to poor outcomes remains unknown.

TL;DR: These parameters were developed by the Joint Task Force on Practice Parameters, representing the American Academy of Allergy, Asthma & Immunology (AAAAI); the American Col- lege of Allergen,Asthma & immunology (ACAAI); and the Joint Council of All allergy, asthma, and Immunology.
Abstract: These parameters were developed by the Joint Task Force on Practice Parameters, representing the American Academy of Allergy, Asthma & Immunology (AAAAI); the American Col- lege of Allergy, Asthma & Immunology (ACAAI); and the Joint Council of Allergy, Asthma & Immunology. The American Academy of Allergy, Asthma & Immunology and the American College of Allergy, Asthma & Immunology have jointly accepted responsibility for establishing ''Allergen immunotherapy: A practice parameter third update.'' This is a complete and com- prehensive document at the current time. The medical environ- ment is a changing environment, and not all recommendations will be appropriate for all patients.

TL;DR: Injections of peanut extract increase the tolerance of patients with peanut allergy to oral ingestion of peanuts, even during maintenance injections, which result in repeated systemic reactions in most patients.
Abstract: Background: Immediate hypersensitivity to peanuts is a frequent cause of anaphylactic reactions and deaths in children and adults Currently, preventive treatment consists of avoidance, which is difficult because of the widespread and often disguised use of peanuts in the food industry Methos: Twelve patients with immediate hypersensitivity to ingestion of peanuts were recruited Half were treated with injections of peanut extract: a maintenance level of tolerance was first achieved by a rush protocol, then maintained with weekly injections for at least 1 year The other six were untreated control subjects All patients underwent double-blind, placebo-controlled, oral peanut challenges initially, after approximately 6 weeks, and after 1 year Results: All treated patients achieved the maintenance dose of 05 ml of 1:100 wt/vol peanut extract by the rush injection protocol All experienced increased tolerance to double-blind, placebo-controlled peanut challenge and decreased sensitivity on titrated skin prick testing with peanut extract, whereas the threshold to oral peanut challenge and cutaneous reactivity to peanut extract were unchanged in the untreated control subjects Systemic reactions were common in the treated group both during rush immunotherapy and with maintenance injections Only three patients remained tolerant of the full maintenance dose The increased tolerance to oral peanut challenge was maintained in the three subjects who received full maintenance doses, but there was partial ( n =2) or complete ( n =1) loss of protection in the patients who required dose reduction because of systemic reactions Conclusions: Injections of peanut extract increase the tolerance of patients with peanut allergy to oral ingestion of peanuts Injections result in repeated systemic reactions in most patients, even during maintenance injections For clinical application of this method of treatment, a modified peanut extract is needed

TL;DR: A single dose of IL-4R appears safe and effective in moderate asthma, and the 1,500 microg dose appears as safe but significantly more effective than the 500microg dose.
Abstract: Interleukin-4 mediates important proinflammatory functions in asthma, including induction of the IgE isotype switch, expression of VCAM-1 on endothelium, mucin production, 15-lipoxygenase activity, and Th2 lymphocyte stimulation leading to the secondary synthesis of IL-4, IL-5, and IL-13. Soluble recombinant human IL-4 receptor (IL-4R; Nuvance; altrakincept) inactivates naturally occurring IL-4 without mediating cellular activation. Nebulized IL-4R has a serum half-life of approximately 1 wk. In this double-blind, placebo-controlled trial, 25 patients with moderate asthma requiring inhaled corticosteroids were randomly assigned to receive a single nebulized dose of IL-4R 1,500 μ g, IL-4R 500 μ g, or placebo after stopping inhaled corticosteroids. No drug-related toxicity was observed. Treatment with IL-4R produced significant improvement in FEV1 on Day 4 (1,500 μ g versus placebo; p < 0.05) and in FEF25–75 on Days 2 and 4 (1,500 μ g versus placebo; p < 0.05). Asthma symptom scores stabilized among patient...

TL;DR: This review examines evolving concepts of sepsis and discusses new and potential therapies, including therapy with activated protein C, stringent control of blood glucose, and early goal-directed therapy to treat cellular oxygen deficit.
Abstract: Sepsis is the leading cause of death in critically ill patients in the United States. Yet the individual host response to septicemia is variable, depending on the patient's immune response, age, nutritional status, and coexisting conditions, as well as on the virulence of the organism and the size of the inoculum. This review examines evolving concepts of sepsis and discusses new and potential therapies. Recent clinical advances include therapy with activated protein C, stringent control of blood glucose, and early goal-directed therapy to treat cellular oxygen deficit. Future therapies may be focused on modulating the immune response in the light of the characteristics of the specific pathogen, the genetic profile of the patient, and the duration of the disease.

TL;DR: The ARIA guidelines for the management of allergic rhinitis and asthma are similar in both the 1999 ARIA workshop report and the 2008 Update as discussed by the authors, but the GRADE approach is not yet available.
Abstract: Allergic rhinitis is a symptomatic disorder of the nose induced after allergen exposure by an IgE-mediated inflammation of the membranes lining the nose. It is a global health problem that causes major illness and disability worldwide. Over 600 million patients from all countries, all ethnic groups and of all ages suffer from allergic rhinitis. It affects social life, sleep, school and work and its economic impact is substantial. Risk factors for allergic rhinitis are well identified. Indoor and outdoor allergens as well as occupational agents cause rhinitis and other allergic diseases. The role of indoor and outdoor pollution is probably very important, but has yet to be fully understood both for the occurrence of the disease and its manifestations.
In 1999, during the Allergic Rhinitis and its Impact on Asthma (ARIA) WHO workshop, the expert panel proposed a new classification for allergic rhinitis which was subdivided into 'intermittent' or 'persistent' disease.
This classification is now validated. The diagnosis of allergic rhinitis is often quite easy, but in some cases it may cause problems and many patients are still under-diagnosed, often because they do not perceive the symptoms of rhinitis as a disease impairing their social life, school and work.
The management of allergic rhinitis is well established and the ARIA expert panel based its recommendations on evidence using an extensive review of the literature available up to December 1999. The statements of evidence for the development of these guidelines followed WHO rules and were based on those of Shekelle et al. A large number of papers have been published since 2000 and are extensively reviewed in the 2008 Update using the same evidence-based system. Recommendations for the management of allergic rhinitis are similar in both the ARIA workshop report and the 2008 Update. In the future, the GRADE approach will be used, but is not yet available.
Another important aspect of the ARIA guidelines was to consider co-morbidities. Both allergic rhinitis and asthma are systemic inflammatory conditions and often co-exist in the same patients. In the 2008 Update, these links have been confirmed.
The ARIA document is not intended to be a standard-of-care document for individual countries. It is provided as a basis for physicians, health care professionals and organizations involved in the treatment of allergic rhinitis and asthma in various countries to facilitate the development of relevant local standard-of-care documents for patients.
