The POLISMAIL lesson: Sublingual immunotherapy may be prescribed also in polysensitized patients
International journal of immunopathology and pharmacology (Impact Factor: 1.62). 04/2010; 23(2):637-40.
Polysensitization is a feature of allergic rhinitis (AR) that significantly impairs the quality of life (QoL) of AR patients. Allergen-specific immunotherapy is the only causal therapy for AR. However, the polysensitization phenomenon may represent a crucial obstacle as far as it concerns the choice of the allergen extract which should be used for immunotherapy. Therefore, a real-life based multi-centre study, named POLISMAIL, has been designed which aims at evaluating the behaviour of some allergists managing polysensitized AR patients. The effect of two-year SLIT treatment in those patients was also evaluated. A single allergen extract was used for two-thirds of patients, whereas a mix of two allergens was chosen for the remaining patients. The severity grade of AR and the type of diagnosis were significantly improved by 2-year SLIT. In addition, SLIT significantly improved QoL. Both outcomes confirm that SLIT with one or two allergen extracts achieves a significant improvement in polysensitized patients. In conclusion, the POLISMAIL study demonstrates that polysensitization should not represent a counter-indication for prescribing immunotherapy. The choice to limit SLIT to 1-2 allergen extracts was sufficient and effective in improving symptoms and QoL.

ABSTRACT: INTRODUCTION: Polysensitization, that is, sensitization to more than one allergen family, is a common feature of patients with allergic rhinitis (AR) and significantly impairs their quality of life (QoL). Allergen-specific immunotherapy is the only causal treatment for AR. However, the polysensitization phenomenon may represent a crucial obstacle as far as it concerns the choice of the allergen extract to be used for immunotherapy. AREAS COVERED: A series of real-life based multi-center studies, named POLISMAIL (Polysensitization Impact on Allergen Immunotherapy), have been designed with the aim of evaluating the behavior of allergists in managing polysensitized AR patients. The effect of immunotherapy treatment in these patients was also evaluated. A single allergen extract was used in two-thirds of patients, whereas a mix of two allergens was chosen in the remaining. The severity grade of AR and the QoL were significantly improved by immunotherapy. Both outcomes confirmed that immunotherapy with one or two allergen extracts achieves a significant improvement in polysensitized patients. EXPERT OPINION: In conclusion, POLISMAIL studies demonstrate that polysensitization should not represent a counter-indication for prescribing immunotherapy. The choice of limiting sublingual immunotherapy to one to two allergen extracts, preferably separated and at high dosages, is sufficient and effective in improving symptoms and QoL.Expert opinion on biological therapy 06/2011; 11(6):715-22.

ABSTRACT: Oralair(®) is a sublingual grass pollen immunotherapy tablet that was authorized for use in Europe on 26 November 2009 and is currently in Phase III clinical trials in the USA. It is indicated for the management of grass pollen allergic rhinitis with or without conjunctivitis in adults, adolescents and children (above the age of 5) with clinically relevant symptoms, confirmed by a positive cutaneous test and/or a positive titer of the specific IgE to the grass pollen. Treatment is composed of an initiation phase (3-day dose escalation: 100 IR [index of reactivity] on day 1, 200 IR on day 2 and 300 IR on day 3) and a continuation phase at a dosage of 300 IR/day. Treatment is scheduled to start approximately 4 months before the actual start of the pollen season and should be continued throughout the season. The treatment should be prescribed and initiated by an experienced allergy specialist.Expert Review of Clinical Immunology 07/2011; 7(4):437-44. DOI:10.1586/eci.11.36 · 2.48 Impact Factor
