Tolerance of peanuts and tree nuts in Spanish children with exclusive sensitization to lipid transfer proteins.

Background: Allergy to peanuts and tree nuts is a common cause of food allergy in Spain, with lipid transfer proteins (LTP) being the most frequently recognized panallergen. LTP sensitization often leads to multiple food group sensitivities, resulting in overly restrictive diets that hinder patient's quality of life. This study aimed to assess the tolerance of peanuts and tree nuts (hazelnuts and walnuts) in children sensitized to LTP, potentially mitigating the need for such diets.

In Search of an Association Between Genotype and Phenotype in Hereditary Angioedema due to C1-INH Deficiency.

Hereditary angioedema due to C1 inhibitor deficiency (C1-INH-HAE) is caused by mutations affecting the SERPING1 gene. Adult patients (≥ 18 years old) diagnosed with C1-INH-HAE were clustered according to a modified SERPING1 gene mutation classification [5]. Demographic, clinical, and laboratory data were studied.

Biologics in the treatment of severe asthma.

Severe asthma is defined as asthma which requires treatment with high dose inhaled corticosteroids and with a second controller drug to prevent it from becoming uncontrolled or which remains uncontrolled despite this therapy. Patients with uncontrolled severe asthma require additional treatment options as add-on therapy, including biologics. Biologic therapies in asthma are designed to block key immune regulators, such as IgE, or certain pro-inflammatory cytokines, e.
