Rhinitis describes inflammation of the nasal mucosa, but is clinically defined by symptoms of runny nose, itching, sneezing, and nasal congestion or congestion. Patients with non-inflammatory type rhinitis are thought to suffer from dysfunction of the autonomic nerve supply to the nasal mucosa.67,113. Occupational rhinitis, which may be allergic or nonallergic, describes abnormalities of the nasal mucosa mediated by airborne substances in the work environment.

Symptoms of sneezing, itchy nose, itchy palate more often lead to allergic rhinitis. Objective measurements of the nasal airway are not performed in routine clinical practice, but may be useful when allergen or aspirin challenges are performed, and may be useful when septal surgery or turbinate reduction is being considered.

Not routinely available outside specialized centers; there is no standardized methodology and asthmatic reactions may occur. Those with nasal obstruction unresolved by pharmacotherapy or structural abnormalities, such as a deviated septum, sufficient to make nasal therapy difficult should be seen by a surgeon. It is important to use a drug with the least adverse effect and considered safe for the current situation (eg pregnancy, breastfeeding).

They act primarily on neurally mediated symptoms of itching, sneezing, and rhinorrhea, and have only a modest effect on nasal congestion.158-164 Furthermore, they reduce histamine-induced symptoms such as itching165 at sites other than the nose, such as conjunctiva. palate and skin.166-168 They should be used regularly rather than "as needed" in persistent rhinitis.169,170 Acrivastine has the fastest onset of action but must be used 8 hours; Fexofenadine is the least sedating oral antihistamine with a broad therapeutic index. Addition of intranasal steroids for persistent moderate/severe rhinitis not controlled with topical intranasal corticosteroids alone, especially when ocular symptoms are present. .181. These are superior to oral antihistamines in alleviating rhinitis symptoms,182 and in reducing nasal obstruction,183,184 although they do not improve symptoms due to histamine at other sites, such as on the skin.

It has a rapid onset of action (15 minutes), faster than oral antihistamines,185 so the drug can be used on demand as rescue therapy for a flare-up of symptoms. However, continuous treatment is clinically more effective than on-demand use.186 It can be effective in patients in whom oral antihistamines have previously failed.187 Treatment with both intranasal and oral antihistamines does not bring additional benefits in relieving nasal symptoms.187 They are less effective. as an intranasal steroid in the relief of symptoms of allergic rhinitis.188. It is a first-line treatment for mild to moderate intermittent and mild persistent rhinitis.

Intranasal steroids used for moderate/severe persistent rhinitis not controlled by topical intranasal corticosteroids alone.

Combination of topical AH with INS should be used in patients when symptoms remain uncontrollable on AH or INS monotherapy or on a combination of oral AH plus INS. There are no trials of oral steroid use and efficacy in AR, although there is grade A evidence in chronic rhinosinusitis with nasal polyposis where inflammation is more severe. In order to achieve control, short-term rescue medication is used during severe exacerbations despite compliance with conventional pharmacotherapy.

It is important to ensure that intranasal steroid therapy is given concurrently with oral steroids with or without a short-term decongestant spray to allow intranasal penetration of the drug (see below). Injected preparations are not recommended, as the risk-benefit profile for intramuscular corticosteroids is poor compared to other available treatments.204,205. For example, oxymetazoline and fluticasone furoate, when used together, further improved nasal congestion more than either alone.207 There is currently no licensed combination preparation of INS and decongestant in the UK.

Only short-term use (usually less than 10 days) is recommended, as there may be a paradoxical increase in nasal congestion due to retrograde vasodilatation (medication rhinitis).208 The risk of this phenomenon increases with a maximum duration of 3-5 days.209,210 Intranasal decongestants are less likely, to cause rhinitis medicamentosa when used short-term and together with an intranasal steroid.210 They may also cause nasal irritation and may increase rhinitis. They are poorly effective in reducing nasal congestion212 and have many side effects, so they are not recommended.213. These have a therapeutic profile similar to antihistamines, with efficacy comparable to loratadine in seasonal allergic rhinitis,214 and are less effective than topical nasal corticosteroids.214-217 Response is less consistent than with antihistamines.218-220 LTRAs reduce mean daily rhinitis symptoms achieves 5% more than placebo.155.

Montelukast is approved in the UK for people with seasonal allergic rhinitis who also have concurrent asthma (UK license for age > 0.6 months; Zafirlukast UK license > 12 years).

In view of the risk of systemic side effects, SCIT should only be administered in specialized clinics by trained personnel with direct access to adrenaline and resuscitation facilities248. Sublingual immunotherapy is well tolerated, with side effects largely limited to local itching and swelling in the mouth and throat. After supervision of the first dose by the prescriber with a one-hour observation period, SLIT is administered daily at home.

Oral antihistamines given prior to the start of SLIT and during the first two weeks of treatment may reduce local oral irritation (level D). Allergen immunotherapy is recommended in the UK in patients with a history of symptoms on exposure to allergens and objective confirmation of IgE sensitivity (skin prick test positive and/or elevated allergen-specific IgE) in the following circumstances265: 1. The complex immunopathology includes elevated IgE levels , mast cells, eosinophils and other inflammatory cells in the conjunctival epithelium.

The condition is sight-threatening because the corneal epithelium is attacked by products of immune reactions in the conjunctiva. The American Academy of Asthma, Allergy, and Clinical Immunology Task Force is conducting a database search to identify knowledge gaps and research needs, and their full report is expected. There are no well-conducted (prospective and randomized) studies supporting the use of coblation, laser, or inferior turbinate surgery in patients with rhinitis that demonstrate benefit supported by objective measurements other than in the short term.

Studies of this type show no lasting benefit from surgery of the inferior turbinate.299 If future attempts at surgery are to be made, it appears that they should be primarily limited to patients who have not responded to treatment in light of the evidence that currently available for sale.

Since 2001, the ARIA patient classification system for allergic rhinitis has been used in both clinical and research settings. Poor adherence is a challenge in the management of allergic and non-allergic rhinitis, just as it is in other chronic diseases where generic estimates of non-adherence range from 30 to 60% and from 50 to 80% for preventive measures.306 . Rhinitis in pregnancy may not be adequately treated during routine prenatal care, and patients benefit from a multidisciplinary approach. .314 Informing the patient that pregnancy-induced rhinitis is a self-limiting condition is often reassuring.

During pregnancy, most medications cross the placenta and should be prescribed only when the apparent benefit outweighs the risk to the fetus.317 Nasal irrigation is safe and effective in pregnant women, reducing the need for antihistamines.318 Chromones are not indicated. teratogenic effects in animals and are the safest drug recommended in the first 3 months of pregnancy, although they require multiple daily administrations. There is considerable clinical experience with chlorphenamine, loratadine and cetirizine in pregnancy, which may be used adjunctively, but decongestants should be avoided. 322,323 Patients already on immunotherapy can continue if they have already reached the maintenance phase, but each case must be considered individually. Both loratadine324 and cetirizine appear safer with low levels found in breast milk.325 The lowest dose should be used for the shortest duration.

Recommending continuous use of intranasal steroids can often create anxiety in parents; intranasal steroids with low bioavailability have a better safety profile at recommended doses and should be preferred (Figure 4)335,336. Immunotherapy is recommended for subjects who have not responded adequately to maximal pharmacotherapy; the potential additional benefit of disease prevention should be considered when treating children337,338. Both children and carers should have the relevant information and appropriate training339.

Commonly used and validated disease-specific quality of life scoring systems include the RQLQ for allergic rhinitis and rhino-conjunctivitis, the SNOT-22 or RSOM-31 in chronic rhinosinusitis, and a modified SNOT-16 in acute rhinosinusitis.

Although theoretically the relationship between allergen exposure and clinically relevant symptoms can be confirmed only by a controlled challenge, the presence of a positive test with
