The relevance of the problem of urticaria is generally recognized. The chronic infection foci, gastrointestinal diseases, diabetes mellitus, malignant neoplasms, etc. are among the factors that initiate the manifestation of the disease. However, the studies devoted to evaluation of the endocrine glands in such patients remain unaddressed. Although it is known that, in particular, the thyroid gland takes an active part in the development of allergic dermatoses. Objective: To study the thyroid hormone balance in patients with chronic idiopathic urticaria.
Stevens–Johnson syndrome (SJS), which is a drug-induced disease in 50% of cases, is increasingly common in everyday practice. A determining role in the pathogenesis of pathological conditions (inflammation, shocks of various genesis, etc.) plays a unique extra- and intracellular messenger, i. e., the nitrogen oxide (NO) system acts as an endogenous regulator in various dermatoses. In physiological concentrations, NO interacting with reactive oxygen species exhibits antioxidant properties, in case of metabolic disorders associated with the NO accumulation in tissues, and said reactions promote highly toxic substances adversely affecting the disease course. The NO biological action wide scope determines the interest in studying the NO-NOS system (nitrate ions (NO3-), nitrite ions (NO2-)) in patients with SJS, which is accompanied by the involvement of all body systems and defines the disease prognosis.
