Psoriasis is chronic inflammatory skin disease that can develop at any age. Approximately 20–30% of all patients report about first rashes before the age of 18. Psoriatic arthritis is one of psoriasis comorbid conditions. Its signs can range from mild to extremely severe destructive forms. Arthralgia, joint stiffness and swelling are the most common symptoms. Early psoriatic arthritis treatment onset allows to control joint damage which usually occurs during the first 2 years of the disease. The moderate and severe course of psoriasis and psoriatic arthritis may require systemic therapy, however, there is not much data on the efficacy and toxicity of systemic agents in the pediatric practice. This article provides the review of studies on etanercept efficacy and safety in children with psoriatic arthritis.
Reduced skin barrier properties in patients with atopic dermatitis (AtD) are largely caused by microbiome changes and extensive Staphylococcus aureus colonisation of the skin. In this regard, the integument of patients with AtD requires constant care and the use of various emollients. The inclusion of lysates of non-pathogenic microorganisms and prebiotics in the composition of emollients ensures the normalisation of the microbiome composition and the immunological barrier of the skin. The article presents the results of our own observations on the application of two cosmetic scin-care products for damaged skin with vitamin F in children with AtD complicated by a secondary infection, while the composition of one of the products is additionally enriched with ceramides and prebiotics. The safety and high efficacy of both products have been shown, however, the presence of ceramides and prebiotics in the emollient composition makes it possible to achieve a marked decrease in the degree of S. aureus colonisation of the skin.
Pruritus is one of the main clinical manifestations of atopic dermatitis, and it significantly reduces the quality of life of patients in childhood. Scientific images on its pathophysiological basis have now undergone significant changes. The histamine exceptional role in pruritus development was confounded, as well as data on immune system involvement in its maintenance was given. This article presents current data on differential approaches to pruritus management depending on its etiopathogenetic characteristics. The role of dermocosmetics in restoration of the skin barrier as the first stage prevention of pruritus in atopic dermatitis was considered. The results of clinical studies showing efficacy of topical agents (innovative component with anti-pruritic action — STIMU-TEX) application are presented.
Atopic dermatitis is a chronic inflammatory disease characterized by relapsing course, severe itching, erythema and dry skin due to skin barrier defects and staphylococcus infection. According to current guidelines for the treatment of atopic dermatitis (prepared by dermatological societies) the background therapy is prolonged application of emollients directly on the skin and its use during bathing. Clinical studies have shown that repeated administration of emollients moisturizes the skin, restores its barrier and normal functioning, and reduces the amount of glucocorticosteroids needed for atopic eczema therapy in infants, children and adults. The results of trials and long-term clinical practice have proven that emollients are safe and effective in patients with atopic dermatitis. This article presents the information based on the recent data concerning emollients: their characteristics, mode of action, role in atopic dermatitis treatment, and results of clinical trials conducted in such patients.
Atopic dermatitis (AtD) is multifactorial inflammatory skin disease, one of the aspects of its pathogenesis is epidermal barrier dysfunction. Early development of AtD is associated with filaggrin dysfunction. Filaggrin is a protein involved in aggregation of keratin filaments in the upper layers of epidermis and the retention of lipids and proteins between corneocytes. Frequently, filaggrin dysfunction can be accompanied with secondary infection and high risk of other allergic diseases development. This can happen due to disturbance in terminal differentiation of epidermal cells and, as consequence, malfunction of epidermal barrier. Thus, the long regular use of emollients is the basis of AtD therapy. New class of emollients (“emollents plus”) allowed us to achieve more significant treatment results in patients with AtD. These emollients reduce inflammatory process activity in the skin by replacing structural components of abnormal epidermal barrier.
IntroductionEpidermal barrier dysfunction in children with atopic dermatitis can cause transcutaneous sensitization to allergens and allergic diseases. We evaluated the effectiveness of an early-intervention algorithm for atopic dermatitis treatment, utilizing pimecrolimus for long-term maintenance therapy, in reducing transcutaneous sensitization in infants.MethodThis was a single-center cohort observational study that enrolled children aged 1-4 months with family history of allergic diseases, moderate-to-severe atopic dermatitis, and sensitization to ≥ 1 of the investigated allergens. Patients who sought medical attention at atopic dermatitis onset (within 10 days) were group 1 “baseline therapy with topical glucocorticoids with subsequent transition to pimecrolimus as maintenance therapy”; patients who sought medical attention later were group 2 “baseline and maintenance therapy with topical glucocorticoids, without subsequent use of pimecrolimus”. Sensitization class and level of allergen-specific immunoglobulin E were determined at baseline, and 6 and 12 months of age. Atopic dermatitis severity was evaluated using the Eczema Area and Severity Index score at baseline and 6, 9 and 12 months of age.ResultsFifty-six and 52 patients were enrolled in groups 1 and 2, respectively. Compared with group 2, group 1 demonstrated a lower level of sensitization to cow's milk protein, egg white and house dust mite allergen at 6 and 12 months of age, and a more pronounced decrease in atopic dermatitis severity at 6, 9 and 12 months of age. No adverse events occurred.DiscussionThe pimecrolimus-containing algorithm was effective in treating atopic dermatitis and prophylaxis of early forms of allergic diseases in infants.Trial registrationhttps://clinicaltrials.gov/NCT04900948, retrospectively registered, 25 May 2021.
