Serum-soluble Fas antigen level in patients with allergic rhinitis: Its relation to specific immunotherapy

There have been conflicting reports on the relationship between Fas/Fas ligand–mediated apoptosis and allergic response. Specific immunotherapy (SIT) is widely used for treatment of allergic diseases. It has long been apparent that SIT results in a reduction in antigen-specific lymphoproliferation, but it is unclear by what mechanism T-cell responses are inhibited by SIT in vivo. In this study, we examined serum-soluble Fas (sFas) levels in patients with allergic rhinitis and healthy subjects. We also examined the effect of SIT on sFas level. Seventy-two patients with allergic rhinitis and 20 healthy subjects were included in this study. Twenty-eight patients were newly diagnosed and 44 patients were treated with SIT for a 5-year or 7-year duration. Serum sFas levels were measured by a sandwich enzyme-linked immunoassay. Mean serum sFas level was 7931 ± 2861 pg/mL in newly diagnosed patients with allergic rhinitis during the pollen season, 8426 ± 2846 pg/mL in patients with allergic rhinitis treated by SIT for a 5-year duration, 8490 2256 pg/mL in patients with allergic rhinitis treated by SIT for a 7-year duration, and 7493 ± 3450 pg/mL in healthy subjects. Serum sFas level was not found to be significantly different among the study groups (p > 0.05). These findings suggest that there is no relation between sFas level and the etiopathogenesis of allergic inflammation in patients with allergic rhinitis and mechanism of action of SIT.

More about this publication?
  • Allergy and Asthma Proceedings is a peer reviewed publication dedicated to distributing timely scientific research regarding advancements in the knowledge and practice of allergy, asthma and immunology. Its primary readership consists of allergists and pulmonologists.

    The goal of the Proceedings is to publish articles with a predominantly clinical focus which directly impact quality of care for patients with allergic disease and asthma and by having the potential to directly impact the quality of patient care. AAP welcomes the submission of original works including peer-reviewed original research and clinical trial results. Additionally, as the official journal of the Eastern Allergy Conference (EAC), AAP will publish content from EAC poster sessions as well as review articles derived from EAC lectures.

    Featured topics include asthma, rhinitis, sinusitis, food allergies, allergic skin diseases, diagnostic techniques, allergens, and treatment modalities. Published material includes peer-reviewed original research, clinical trials and review articles.

    Articles marked "F" offer free full text for personal noncommercial use only.

    The journal is indexed in Thomson Reuters Web of Science and Science Citation Index Expanded, plus the National Library of Medicine's PubMed service.
