@entity9590 may be caused by an @entity56 response or by the vasomotor reaction to cholinergic @entity2915 . The differential diagnosis of these etiologic forms poses a difficult problem for the clinicians. The pathophysiology of @entity2490 is characterized by @entity455 and mucous @entity4 , @entity28523 which may result from such diverse etiologic factors as cholinergic @entity2915 and @entity566 . In our study, we will evaluate total IgE levels in nasal secretions, irrespective of serum of local origin. Fifty-four @entity1 suffering from @entity9590 , aged between 7 and 63 years, were studied. Fourteen presented @entity25488 , while the remaining 40 were affected with the IgE-dependent form. The following tests were done: blood eosinophil count, mucous eosinophyl count, serum IgE (PRIST), cutaneous tests with house dust, acarus and fungal antigens and nasal provocation tests. IgE levels in mucous were also evaluated. The following results were obtained: 1. No significant differences were found in blood eosinophil counts between the groups studied. 2. No significant differences were found in serum IgE levels between the groups studied. 3. Significant differences were found (P less than 0.001) in the levels of eosinophils in mucous among the groups studied. 4. Mucous IgE levels are significantly greater in the @entity56 form than in the vasomotor form of @entity2490 . The level of IgE in mucous serves as a useful but not pathognomic parameters in the differential diagnosis of the different etiologic forms of @entity2490 . As such it should be considered within the context of all clinical and analytic data before a conclusive diagnosis is made.
