Perennial rhinitis and asthma are clinical syndromes representing a range of overlapping pathologies; accurate classification should therefore precede any comparison. Although the sinonasal cavities, trachea and bronchi have a common respiratory mucosa, there are also anatomical differences. For example, the nose has a capacitance vessel network and the lower airways possess smooth muscle, both of which are responsive to neurohumoral influences. The prevalence of rhinitis and asthma has increased over the last three decades. Rhinitis occurs in around 75% of allergic asthmatics while 20% of perennial allergic rhinitics develop asthma. Eosinophils, and their associated proteins and cytokines, may play a central role in both perennial rhinitis and asthma with and without atopy. The characteristic pathology of asthma can be summarized as a chronic, desquamating, eosinophilic bronchitis. Non-allergic rhinitis with eosinophilia is recognized, but without consistent evidence of epithelial damage. Eosinophils are also present in rhinosinusitis with polyposis, particularly in patients with aspirin sensitivity, in whom asthma also often occurs. Increased mast cell activation and mediator release is evident in both perennial rhinitis and asthma following allergen challenge. The importance of mast cells in non-atopic asthma and polyposis is also recognized. Adhesion molecules may also be upregulated, with an increased number and activation of TH2 lymphocytes. However, allergen-resultant T-cell activation may be less marked in the nose than in the lung. Autonomic imbalance also plays a role in both conditions via changes in neural tone to effector tissues, release of neuropeptides, and interplay with cellular recruitment. Pharmacological manipulation of rhinitis and asthma also illustrates the pathological similarities and differences.

Nasal cytology represents a valid method in the differential diagnosis of allergic and non-allergic nasal diseases, as it is simple, safe, non-invasive, cost-effective, and easy to perform both in the medical and paediatric office. In particular, through cytological investigation it is possible to diagnose a group of non-allergic infective rhinitis that still today constitutes a vague aspect of the clinical-diagnostic-therapeutic approach to eosinophilic non-allergic rhinitis (NARES), non-allergic rhinitis mast cell (NARMA), neutrophilic non-allergic rhinitis (NARNA), and eosinophil-mast cell non-allergic rhinitis (NARESMA). Preventive treatment of nasal diseases, when guided by rhinocytograms, leads to a favorable clinical and time-dependent outcome. These advantages are reflected in a better quality of life and in a reduction in National Health Service costs, without chronic evolution of the disease to complications.
