Brief Summary

Allergen specific immunotherapy is currently the only curative intervention for allergic rhinitis (AR). Subcutaneous immunotherapy (SCIT) need to be reinstituted with an interruption of more than 16 weeks in maintenance period, leading to increased time and economic cost burden and difficulties for continuing further treatment for patients. The aim of present study was to develop a novel dose adjustment schedule for such situation and to compare the clinical efficacy and adverse reactions between novel and conventional schedules for dust mite (DM) SCIT of AR subjects.

Outcome Measures

Primary Outcomes (1)

  • The change of Combined Symptom and Medication Score

    CSMS which was calculated as follows: (total nasal symptom scores (TNSS))/4+ MS as recommended by European Academy of Allergy and Clinical Immunology (EAACI) Position Paper. The CSMS score was 0-6, 0 for good therapeutic effect and 6 for poor therapeutic effect.

    baseline, week 3, week 6, week 26.

Secondary Outcomes (3)

  • The change of total nasal symptom scores

    baseline, week 3, week 6, week 26.

  • The change of medication score

    Baseline, week 26.

  • Adverse reactions

    week 26.

Study Arms (3)

Novel dose adjustment schedule

EXPERIMENTAL

The patients in this group had late injections of more than 16 weeks in maintenance period, and restarted SCIT with novel dose adjustment schedule.

Biological: Novel dose adjustment of Alutard SQ

Conventional dose adjustment

ACTIVE COMPARATOR

The patients in this group had late injections of more than 16 weeks in maintenance period, and restarted SCIT with conventional dose adjustment schedule.

Biological: conventional dose adjustment of Alutard SQ

Continuous cluster SCIT schedule

ACTIVE COMPARATOR

The subjects had a routine cluster SCIT schedule without interrupted period.

Biological: Routine continuous cluster of Alutard SQ

Interventions

novel dose adjustment schedule means directly reaching dose of Vial 4, 10,000 SQ

Novel dose adjustment schedule

conventional dose adjustment schedule means restarting from dose of Vial 1, 10 SQ

Conventional dose adjustment

Patient receiving continuous cluster SCIT for DM during the same period

Continuous cluster SCIT schedule
