OBJECTIVE: Allergic rhinitis (AR) is one of the most common diseases affecting adults. It is the most common chronic disease in children in the United States today and the fifth most common chronic disease in the United States overall. AR is estimated to affect nearly 1 in every 6 Americans and generates $2 to $5 billion in direct health expenditures annually. It can impair quality of life and, through loss of work and school attendance, is responsible for as much as $2 to $4 billion in lost productivity annually.

Functional dyspepsia (FD) is common in children, with as many as 80% of those being evaluated for chronic abdominal pain reporting symptoms of epigastric discomfort, nausea, or fullness. It is known that patients with persistent complaints have increased comorbidities such as depression and anxiety. The interaction with psychopathologic variables has been found to mediate the association between upper abdominal pain and gastric hypersensitivity. These observations suggest that abnormal central nervous system processing of gastric stimuli may be a relevant pathophysiologic mechanism in FD.

BACKGROUND: Leukotrienes and prostaglandines are important mediators of inflammation. While prostaglandine synthesis can be influenced by NSAIDs therapeutical approaches to the 5-lipoxygenase pathway are rare. Resinous extracts of Boswellia serrata (H15, indish incense), known from traditional ayurvedic medicine, decrease leukotriene synthesis in vitro. Case reports suggest a clinical role for that drug. METHODS: Outpatients with active RA have been enrolled into a multicenter controlled trial.

Leukotrienes generated by 5-lipoxygenase (5-LOX)-catalyzed reaction are key regulators of inflammation. In ionophore-stimulated (A23187; 1-2.5 μM) human blood neutrophils or differentiated HL-60 cells, vitamin E forms differentially inhibited leukotriene B(4) (LTB(4)) with an IC(50) of 5-20 μM for γ-tocopherol, δ-tocopherol (δT), and γ-tocotrienol, but a much higher IC(50) for α-tocopherol.

Clinical symptoms of allergic and nonallergic rhinitis are similar despite the significant difference in underlying mechanisms. Over-the-counter (OTC) treatments can be used as effective and affordable therapeutic modalities when recommended by a physician. Adjunct treatments, such as herbal medicine, acupuncture and homeopathy, have become increasingly popular. Most of the treatments reviewed in this article are available OTC and are a likely choice for patients suffering from acute or chronic rhinitis.
