The effectiveness of antihistamines in the treatment of atopic dermatitis in children
Abstract
Histamine is one of the key endogenous mediators involved in the regulation of essential physiological and pathological processes in the human body. Its effects are implemented through several types of specific cell surface histamine (H)-receptors. H1-receptors are the most studied ones. The main clinical effects of their stimulation are vasodilation, bronchoconstriction, pituitary gland stimulation of hormone production, increased mucus production by the nasal glands, etc. Histamine H1 receptor antagonists of two generations are pathogeneticaUy justified agents for the treatment of most allergic diseases in accordance with the current clinical guidelines. The second-generation antihistamines that are devoid of sedative effects and are clinically more effective than the first-generation drugs have been currently introduced into the allergic disease treatment practice. They are the main drugs for the treatment of allergic diseases, especially in acute symptoms of the disease. Dimetindene maleate is the drug of choice for the symptomatic treatment of skin lesions, especially in infants. The article presents the result of the analysis of 26 out-patient medical records of infants (aged from 4 to 12 months) with a verified diagnosis of “atopic dermatitis, limited form, in the exacerbation phase”. A mild course of the disease was observed in 17 children, and a moderately severe course in 9 children. The duration of treatment was 7 to 16 days. Against the background of therapy (group 1), the following results were obtained: on day 3 of treatment the SCORAD-TIS index decreased to 16.4 ± 1.6 and on day 7 to 9.1 ± 1.3 points in children with a moderate course, and to 6.7 ± 0.8 and 4.1 ± 0.9 points in children with a mild course, respectively. In the children from group 2, the decrease in SCORAD-TIS was less significant: 19.5 ± 1.5 points on day 3, 12.2 ± 1.1 points on day 7 in children with a moderate course, respectively. Similar values decreased to 9.0 ± 0.9 on day 3, and to 6.9 ± 1.2 points on day 7 in children with a mild course of atopic dermatitis. The conducted analysis demonstrates the high clinical efficacy, good tolerance and the absence of tachyphylaxis of dimetindene maleate, drops. No side effects including those associated with anticholinergic properties (dry mouth, agitation) were identified.
