Results were compared to 30 age-and-sex matched patients with chronic rhinitis who had normal sinus CT scans, and a matched group of asymptomatic, healthy subjects. None of the patients was taking oral corticosteroids and none had ever received allergen immunotherapy. IgA deficiency was present in 3% (2/60) of the patients with chronic rhinitis or sinusitis and IgG deficiency was seen in another two (3%). None of the normals had low IgA or IgG. Low levels of IgG1 or IgG3 were found in some patients in all three groups, while none had low IgG2 levels. Serum levels of IgG, IgA, IgM, IgG1, IgG2, and IgG4 were not significantly different between the groups. Mean serum IgG3 levels, however, were significantly lower in the chronic sinusitis group than the chronic rhinitis group (P < .003) or the normals (P < .0005). The incidence of below normal levels of IgG3 was also more frequent in chronic sinusitis than in chronic rhinitis (P < .04) or normals (P < .002). Patients in the chronic sinusitis group had a high incidence of asthma (57%) and atopy (45%) but there was no difference in immunoglobulin class or IgG subclass levels in matched asthmatics compared with nonasthmatic patients with chronic sinusitis. Atopic patients with chronic sinusitis had a higher frequency of IgG3 subclass deficiency than nonatopics (P = .04).

The tests were performed on either side of the back before and at the time of administration (single dose), then every 30 minutes for two hours, and every hour for the following four hours. Evaluation was based on the mean of two measurements of the surface area of the wheal-and-flare reaction accompanied by assessment of topical pruritus. The response to histamine was decreased markedly in the two active treatment groups. Although within one hour of injection, the activity of both antihistamines was consistently greater than that of placebo, the kinetics of action of the two products nevertheless differed; indeed acrivastine was active against flare and wheal earlier (within 30 minutes); terfenadine proved to be more active than acrivastine only on flare and only at the later times (four, five, and six hours).

Each patient was reevaluated prospectively at least once each year and a diagnosis of asthma was accepted if the subject developed episodic wheezing and/or cough plus airway obstruction and at least a 15% increase in FEV1 after inhaled salbutamol. Those subjects who developed asthma and ten individuals who did not develop asthma were rechallenged after the first asthma symptoms or at the end of the followup period, respectively. Risk of developing asthma during the followup period (mean of 43.8 months, range 36 to 70) was similar (P > .05) in those individuals who previously had airway hyperresponsiveness (2 of the 19 patients), when compared with subjects who were previously nonresponders (4 of the 47 patients). Further, in those subjects who developed asthma, geometric mean (range) PC20 decreased from 11.75 (0.40 to 50) during the initial evaluation to 1.66 (0.15 to 11.07) mg/mL after the first asthma symptoms (P < .05). No significant modifications of PC20 were detected in subjects who did not develop asthma.
