ABSTRACT
The relationship between sinusitis and status asthmaticus (SA) remains obscure. The purposes of this study were to determine the prevalence of abnormal sinus radiographs (SXRs) and investigate possible risk factors among unselected children admitted with SA. Eighty-eight patients over 2 years of age (range 2 to 16 years) consecutively admitted with SA were studied. The principal investigator, blinded to SXR findings, interviewed and examined the patients with respect to 10 physical parameters and 14 historical parameters. Two staff radiologists, blinded to the clinical findings, interpreted the SXRs. Relationship of historical and physical findings with positive SXRs was determined by statistical analysis. Twenty-seven percent of patients were found to have abnormal SXRs, manifesting two thirds or greater opacification of the sinuses. The mean age, sex, and race of patients with abnormal SXRs was not significantly different from those with normal films. A history of two or more admissions per year for SA, and, in children under 5 years of age, a history of chronic otitis media, and the physical finding of otitis media were significantly more frequent among patients with abnormal SXRs. Although not found to be statistically significant, a history of sinusitis and cough occurred more frequently in association with abnormal SXRs.

Six of 12 patients with corticosteroid-dependent bronchial asthma and recurrent sinopulmonary infections were found to have significant abnormalities in quantitative immunoglobulins and/or IgG subclasses. Five patients had a combined quantitative immunoglobulin and IgG subclass deficiency and one patient had an isolated IgG deficiency. Combined IgG subclass deficiencies were observed in two patients, both with deficiencies of IgG2 and IgG3. The most common IgG subclass deficiencies were of IgG2 and IgG3, which were found in three patients each.

Three generations of relatives of 58-year-old nonidentical twins with chronic bronchitis and fibrotic lung disease were evaluated. Sera of 23 family members, 14 with a history of excessive sinopulmonary infections, were examined for deficiencies of immunoglobulin classes, IgG subclasses, and specific antibody to tetanus toxoid and Hemophilus influenzae type b. Of 14 symptomatic family members, 12 had serum IgE concentrations less than 5 IU/ml. Four had values less than 1 IU/ml. Serum IgE was greater than 10 IU/ml in all nine asymptomatic individuals. Inheritance of low IgE appeared to be autosomal dominant, with variable penetrance. IgA was low normal (70-90 mg/dl) in three individuals. Two of these were IgE deficient. One symptomatic child had unmeasurable IgG2 (less than 10 mg/dl) and IgE (less than 0.5 IU/ml). This kindred demonstrates that IgE deficiency can be familial, and associated with sinopulmonary disease.
