Abstract
A clinical study of 134 patients (65 males, 69 females) who started allergen immunotherapy in the Department of Otorhinolaryngology at Nippon Medical School Hospital between April 2010 and May 2012 was performed. We examined the age distribution, the initial and maintenance doses, the number of injections, the rate and the details of side effects, the number of patients who discontinued treatment, and the number of days that the patients took medication. There are 69 patients (51.5%) aged 30 to 49 years and 18 patients (13.4%) aged three to 14 years. There was a wider range of initial and maintenance doses for patients receiving Japanese cedar immunotherapy than for those with allergies to house dust. Five patients experienced a side effect during immunotherapy, but there were no fatalities. Twenty-two patients (16.4%) discontinued immunotherapy. Twenty-eight percent of the patients who received cedar immunotherapy did not need to take medication during the cedar season in 2012.
