[Occupational rhinitis and allergic conjunctivitis].
Occupational rhinitis is an inflammatory disease of the nose, which is characterised by intermittent or persistent symptoms, arising from causes and conditions attributable to a particular work environment and not from stimuli encountered outside the workplace. Its clinical symptoms such as nasal congestion, sneezing, rhinorrhoea, itching, nasal airflow limitation are very similar to the symptoms of allergic rhinitis caused by other (classical) agents. Occupational allergic conjunctivitis is an IgE mediated disease, provoked by a substance in the air of the workplace. Its clinical signs (itching, tearing, conjunctival hyperaemia and oedema and, in some cases when the cornea is also involved, blurred vision, photosensitivity) are similar to other forms of allergic conjunctivitis. Risk factors (which in most of the cases occur in both diseases) include history of atopy, high concentration of the irritant agent and multiple irritant agents in the air of the workplace. Atopy has been associated with an increased risk of specific sensitisation to a variety of high molecular weight agents. For the diagnosis of occupational rhinitis and occupational allergic conjunctivitis objective investigations such as allergen specific provocations are necessary in addition to clinical and occupational history. Management of these occupational diseases needs environmental interventions (increasing ventilation, decreasing the time of exposure, substitution of the irritant agent). Medical treatment of occupational rhinitis is very similar to other allergic diseases: oral antihistamines, local (nasal) corticosteroids, combined (antihistamine plus membrane stabilizer) eyedrops. The most important step in medical treatment of occupational allergic conjunctivitis is the daily application of combined eyedrops (for example: olopatadine). Orv. Hetil., 2014, 155(5), 170-175.
