Real-World Safety and Efficacy Clinical Data of an Improved Allergen-Specific Immunotherapy Product for the Treatment of Bee Venom Allergy.

The aim of this study is to explore the safety and efficacy of bee venom immunotherapy without HSA, in real-life patients. Methods: This is an observational retrospective study developed in seven hospitals in Spain, where patients treated with this immunotherapy were included. They gathered the protocol used to initiate the immunotherapy, adverse reactions, field re-stings, and the patient clinical data (clinical history, biomarkers, and skin prick test).

Fungi Sensitization in Spain: Importance of the Species and Its Major Allergen Alt a 1 in the Allergenicity.

Prevalence of allergy to fungi is around 3-10%. The most prevalent species involved in sensitizations are and . Our main objective was to estimate the prevalence of fungal sensitization and its variation across Spain.

Frontline Science: The expression of integrin α β (CD11d/CD18) on neutrophils orchestrates the defense mechanism against endotoxemia and sepsis.

Neutrophil-macrophage interplay is a fine-tuning mechanism that regulates the innate immune response during infection and inflammation. Cell surface receptors play an essential role in neutrophil and macrophage functions. The same receptor can provide different outcomes within diverse leukocyte subsets in different inflammatory conditions.

Inhibition of focal adhesion kinase increases adult olfactory stem cell self-renewal and neuroregeneration through ciliary neurotrophic factor.

Constant neuroregeneration in adult olfactory epithelium maintains olfactory function by basal stem cell proliferation and differentiation to replace lost olfactory sensory neurons (OSNs). Understanding the mechanisms regulating this process could reveal potential therapeutic targets for stimulating adult olfactory neurogenesis under pathological conditions and aging. Ciliary neurotrophic factor (CNTF) in astrocytes promotes forebrain neurogenesis but its function in the olfactory system is unknown.

Intradermal Phleum pratense allergoid immunotherapy. Double-blind, randomized, placebo-controlled trial.

Background: In allergology, the intradermal approach is generally used to establish an aetiological diagnosis, with limited experience in specific allergen immunotherapy.

Objective: To evaluate the efficacy and safety of immunotherapy with an allergen extract of glutaraldehyde-polymerized Phleum pratense, administered intradermally, in patients with rhinoconjunctivitis sensitized to grass pollen.

Methods: Multicentre, randomized, double-blind, placebo-controlled clinical trial in patients from 12 to 65 years of age with rhinitis or rhinoconjunctivitis, with or without asthma, due to grass pollen allergy.
