The immunological response of 30 patients with acute sinusitis was examined by using an enzyme-linked immunosorbent assay (ELISA) designed to detect antibodies against outer membrane vesicles of Haemophilus influenzae. Using this ELISA, we found that 15 patients had slight increases in specific antibody in their convalescent serum. Maxillary sinus secretions from 15 patients had specific antibodies. IgG and IgA antibodies were detected with equal frequency, but IgA antibody was often found in maxillary sinus secretions while it was absent from serum. Thus it appears that patients with acute sinusitis respond systemically and locally with the specific antibody to H. influenzae.

Maxillary sinus aspiration and quantitative culture of the aspirate were performed in 50 patients, ranging in age from 1 to 16 years, with clinical and radiographic evidence of acute sinusitis. Of 79 sinuses aspirated, at least one was found to be infected in 35 (70%) children. Streptococcus pneumoniae, Branhamella catarrhalis, and Haemophilus influenzae were the most common organisms recovered. All H. influenzae were nontypeable. Twenty percent of the H. influenzae and 27% of the B. catarrhalis organisms were beta-lactamase positive and amoxicillin resistant. The subjects received either amoxicillin or cefaclor at a dose of 40 mg/kg/day in three doses for 10 days. The clinical cure rate with amoxicillin was 81%, compared to 78% with cefaclor. Radiographic improvement was similar in both treatment groups. Antibiotic therapy failed in four patients; three had been given amoxicillin, and one cefaclor. In three of these, a beta-lactamase-positive antibiotic-resistant bacterial species was recovered from the maxillary sinus aspirate; the fourth aspirate was sterile.

Signs, symptoms, and radiographic abnormalities of sinusitis are frequent in children with asthma; it is not known whether sinus inflammation is associated with bacterial infection or other mechanisms. Eight asthmatic patients with exacerbation of asthma despite bronchodilator therapy were studied after maxillary sinusitis was confirmed by radiographs. All had cough, wheezing, nasal stuffiness, rhinorrhea and were afebrile. Four patients had headaches, and two had facial pain. Maxillary sinus aspirates were obtained, and bacterial cultures were positive in five: Branhamella catarrhalis (2), nontypeable Hemophilus influenzae (2), Streptococcus pneumoniae (1). Nose and throat cultures did not correlate with sinus cultures. All patients received bronchodilators, and four of eight patients received steroids. All were treated for 14 to 28 days with antibiotics during which seven of the eight patients improved clinically including all with positive sinus cultures. Asthma-symptoms diary scores were kept by five; all demonstrated improvement. Pulmonary-function tests improved in five of seven patients after the antibiotic and asthma therapy including the four patients with positive cultures. Sinus radiographs cleared in three, improved in three, and were unchanged in two patients after antibiotic therapy.
