Introduction: There is no detailed comparison of allergen-specific immunoglobulin responses following sublingual immunotherapy (SLIT) and subcutaneous immunotherapy (SCIT).

Objective: We sought to compare nasal and systemic timothy grass pollen (TGP)-specific antibody responses during 2 years of SCIT and SLIT and 1 year after treatment discontinuation in a double-blind, double-dummy, placebo-controlled trial.

Methods: Nasal fluid and serum were obtained yearly (per-protocol population, n = 84).

Background: Staphylococcus aureus has been implicated in the pathophysiology of eczema, allergic rhinitis, asthma, and food allergy. S aureus is a marker of more severe eczema, which is a risk factor for food sensitization/allergy. Therefore it might be that the association between S aureus and food allergy in eczematous patients is related to eczema severity.

Background: Most milk-allergic children tolerate baked milk.

Objective: To investigate the effect of more frequent versus less frequent introduction of higher doses of more allergenic (less heat-denatured) forms of milk (MAFM) on progression to tolerance.

Methods: Milk-allergic children were challenged with increasing doses of MAFM; baked foods were incorporated into the diet; challenges were repeated at 6- or 12-month intervals over 36 months.

Background: Early introduction of dietary peanut in high-risk infants with severe eczema, egg allergy, or both prevented peanut allergy at 5 years of age in the Learning Early About Peanut Allergy (LEAP) study. The protective effect persisted after 12 months of avoiding peanuts in the 12-month extension of the LEAP study (LEAP-On). It is unclear whether this benefit is allergen and allergic disease specific.

Importance: Sublingual immunotherapy and subcutaneous immunotherapy are effective in seasonal allergic rhinitis. Three years of continuous treatment with subcutaneous immunotherapy and sublingual immunotherapy has been shown to improve symptoms for at least 2 years following discontinuation of treatment.

Objective: To assess whether 2 years of treatment with grass pollen sublingual immunotherapy, compared with placebo, provides improved nasal response to allergen challenge at 3-year follow-up.

Background: Early introduction of peanut is an effective strategy to prevent peanut allergy in high-risk infants; however, feasibility and effects on growth and nutritional intake are unknown.

Objective: We sought to evaluate the feasibility of introducing peanut in infancy and explore effects on growth and nutritional intake up to age 60 months.

Methods: In the Learning Early About Peanut Allergy trial, 640 atopic infants aged 4 to 11 months were randomly assigned to consume (6 g peanut protein per week) or avoid peanut until age 60 months.

Article Synopsis
  • A study followed up on infants at high risk for peanut allergy, comparing those who consumed peanuts during the initial trial to those who avoided them for 12 months.
  • Results showed that 18.6% of the peanut-avoidance group developed allergies, while only 4.8% in the peanut-consumption group did, indicating a significant difference.
  • The findings suggest that early peanut consumption may provide lasting protection against developing peanut allergies, even after a period of peanut avoidance.
