Research objective Atopic dermatitis (AtD) is the earliest and most frequent manifestation of the body’s hypersensitivity reaction to environmental allergens. Often manifested in severe form, affecting the skin, can occur in early infancy, childhood. The disease is genetically determined and is chronic. AtD is one of the most common skin diseases (from 20 to 40% in the structure of skin diseases), which occurs in all countries in people of both sexes. In recent years, there has been an increase in the incidence of AtD throughout the world. The disease is more common in highly developed countries and cities (less commonly in rural areas). AtD significantly reduces the quality of life of children, causing psychological discomfort and disrupting their social adaptation. AtD in children is a risk factor for the «atopic march» — the further sequential development of other allergic diseases: allergic rhinitis, pollinosis, allergic conjunctivitis, bronchial asthma. With a reduced immune response of the body, AtD in children can be complicated by the addition of a secondary infection (bacterial, viral, fungal). Such a high incidence rate, a debut in early childhood, a frequently recurring course of the pathological process, and a tendency towards an increase in the forms of the disease resistant to traditional therapy make the details of the pathogenesis of AtD particularly relevant. One of the main roles in the pathogenesis of AtD belongs to the cells of the immune system. The purpose of this article: to systematize the information available today on the immunopathogenesis of atopic dermatitis.

Atopic dermatitis (AD) is the most frequent chronic inflammatory skin disease, and its incidence has been rapidly increasing in developed countries in the last years. AD presents a high degree of heterogeneity due to biases and confounding factors such as age range, sex, or ethnicity. For those reasons, the search for new biomarkers is crucial. At the same time, obesity, which is a global health problem, has also increased over the years. It has been associated with many pathophysiological states, including skin diseases such as AD, mostly in childhood. Obesity promotes a low grade inflammation driven by many different cytokines and adipokines, including leptin, which has a key role in many other diseases due to its pleiotropic effects. Leptin also has a role in both skin and allergic diseases very related to AD. Thus, this adipokine could have an important role in the pathogenesis of AD, especially in its chronicity. Despite the limited literature available, there is some evidence that leads us to consider leptin as an important adipokine in this skin disease. For this reason, here we have reviewed the role of leptin in the pathophysiology of AD.

Atopic dermatitis (AD) is one of the most prevalent inflammatory disease among non-fatal skin diseases, affecting up to one fifth of the population in developed countries. AD is characterized by recurrent pruritic and localized eczema with seasonal fluctuations. AD initializes the phenomenon of atopic march, during which infant AD patients are predisposed to progressive secondary allergies such as allergic rhinitis, asthma, and food allergies. The pathophysiology of AD is complex; onset of the disease is caused by several factors, including strong genetic predisposition, disrupted epidermal barrier, and immune dysregulation. AD was initially characterized by defects in the innate immune system and a vigorous skewed adaptive Th2 response to environmental agents; there are compelling evidences that the disorder involves multiple immune pathways. Symptomatic palliative treatment is the only strategy to manage the disease and restore skin integrity. Researchers are trying to more precisely define the contribution of different AD genotypes and elucidate the role of various immune axes. In this review, we have summarized the current knowledge about the roles of innate and adaptive immune responsive cells in AD. In addition, current and novel treatment strategies for the management of AD are comprehensively described, including some ongoing clinical trials and promising therapeutic agents. This information will provide an asset towards identifying personalized targets for better therapeutic outcomes.

Abstract: Introduction: Skin diseases of professional etiology remain to this day an urgent problem, despite the low levels of morbidity according to official statistics, due to the high medical and social significance of this pathology. For early diagnosis of occupational and occupational-related skin pathology, it is necessary to investigate laboratory markers that correlate with this pathology. In this regard, a promising direction is to study the activity indicators of hydrolytic enzymes of neutrophils: alkaline and acid phosphatases, the level of myeloperoxidase. Objective: to study and evaluate the effectiveness of cytochemical methods for diagnosing the reactivity of the body in workers exposed to a chemical factor in the workplace. Research methods: hygienic assessment of working conditions of woodworking workers, assessment of the health status and cytochemical parameters of workers. Analysis of the obtained data by methods of mathematical statistics. Results: A hygienic assessment of working conditions and an inspection, with a complex of cytochemical studies, of 148 employees of the chipboard manufacturing enterprise were carried out. The leading factor affecting the body of workers is chemical. A direct strong correlation (r=0.7) was established between the level of dermatological morbidity and the indicators of air pollution of the working area with formaldehyde. Skin pathology was detected in 32.4% of the examined workers. At the same time, the indicators of cytochemical activity in the examined group correlated with the degree of severity of the skin process. Conclusions: Cytochemical indicators in combination with other clinical and diagnostic studies allow us to assess the risk of developing professional and professionally caused skin pathology, which allows us to use them for early diagnosis, and thus contribute to the preservation of labor potential and social adaptation of workers exposed to occupational hazards.

Allergic diseases, in particular, atopic dermatitis, are becoming a global health problem due to the rapid spread, both as an independent disease and as a predictor of the development of bronchial asthma. Discovery of all the processes of the pathogenesis of atopic dermatitis will provide great opportunities for the prevention and treatment of this disease. In this regard, special attention is paid to vitamin D, which becomes more and more popular all over the world every year. In addition to the known and studied consequences of vitamin D deficiency for skeletal system health and mineral metabolism, recent studies have shown that calcitriol, the active form of vitamin D, is involved in many biological processes in the body, including the regulation of the immune system. The discovery of the vitamin D receptor on various cells of the body opens up new prospects for studying the course of various diseases, such as diabetes mellitus, vascular atherosclerosis, obesity, autoimmune diseases, oncology and allergies. The review will be devoted to this problem. 38 foreign and 2 domestic sources are cited.

Metabolic changes in the body of dogs with atopic dermatitis and the causes of its occurrence still remain poorly understood. This study confirms the need for biochemical blood tests for the differential diagnosis of skin diseases in animals. The aim of the research. To identify metabolic changes in dogs with atopic dermatitis. Methods. Serum samples from five ill animals and five intact animals were tested. The diagnosis of the nosological form of skin lesions was established based on the results of anamnesis and clinical manifestations of the disease. Additionally, biochemical studies of the serum of sick animals were performed. Blood of dogs (n=5) was taken from the anterior subcutaneous vein of the forearm or the lateral subcutaneous vein of the tibia into blood tubes. Results. In the study of mineral metabolism, it was found that the concentration of inorganic phosphorus in the serum of sick animals is reduced by only 0.01 mmol/l, but the concentration of total calcium by 10.0 %. The concentration of cholesterol increases 1.3 times and exceeds the reference values by 0.16 mmol/l. In the blood of sick animals, the activity of alanine aminotransferase is significantly reduced by 21.0 % and aspartate aminotransferase – by 20.0 % compared to intact animals. The enzyme gamma-glutamyltransferase probably increases by 1.51 times (P<0.05) in sick dogs, but does not exceed the reference values. Conclusions. It was found that in atopic dermatitis in the serum of dogs decreases the activity of alanine aminotransferase by 21.0 % and aspartate aminotransferase – by 20.0 %, while the activity of gamma-glutamyltransferase increases 1.51 times. The results show the toxic effect of an allergic agent on animals, especially on the liver, which confirms the previous diagnosis – atopic dermatitis.

Keratin Filaments

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.

Objective — to highlight the issue of difficulties in the diagnosis and treatment of patients with pyoderma gangrenosum (PG). Materials and methods. A literature review and analysis of the results of the clinical examination of patients with PG was performed. Pyoderma gangrenosum is most commonly observed in young and middle-aged people, more frequently in women. The pathogenesis of PG has not been fully studied. It is believed to be related to genetic mutations, neutrophil dysfunction and impaired immunity/inflammation regulation. Maverakis and others developed diagnostic criteria for PG. First-line treatment is aimed at optimizing the local wound care. For more severe diseases, systemic therapy is required. Oral corticosteroids (0.5—1 mg/kg/day) are the basis of treatment and used for control of PG. Cyclosporine can be used either alone or in combination with corticosteroids. At present, there is an increasing evidence of effectiveness of biological therapy as treatment method for a number of cytokines. Results and discussion. This article presents a clinical case of a patient diagnosed with PG. Based on recent guidelines, systemic corticosteroid therapy (Medrol starting at 48 mg/d), systemic anti-inflammatory and vascular drugs, topical therapy and treatment results were presented. Conclusions. Without treatment, the disease lasts for months and years. Ulcers sometimes grow very fast, reaching huge sizes in a matter of days. After the healing of some ulcers new ones often emerge. Pain syndrome, the addition of a secondary infection and the continuous progression of the pathological process lead to a decrease in the patient’s quality of life, as well as to a deterioration in his social adaptation. Therefore, timely adequate diagnosis, treatment and full compliance of the patient are the key to success.

Background/Aim. Atopic diseases such as atopic dermatitis, allergic rhinitis and asthma have had increased prevalence during the past decade and nowadays occur in every third child in developed countries. The aim of the study was to determine frequency and type of atopic diseases at the age of two, as well as the importance the total IgE antibodies concentrations have in diagnosis and prognosis of the disease. Methods. The study involved 175 children up to two years of age. Allergy-like symptoms were found after surveying their parents and pediatric medical records. Using the fluorescence immunossay (FIA) method, total IgE antibodies concentrations and specific IgE antibodies (Phadiatop infant) were determined on an Immunocap 100 Dyagnostic System. Results. One or more allergy-like symptoms accounted for 57.7% of findings in children under the age of two, whilst in 19.4% the existence of IgE-related allergic diseases was found. Atopic diseases usually have clinical manifestations of atopic dermatitis (11.4%), IgE-bound wheezing/asthma (10.8%) and food allergies (7.4%), and to much lesser extent those of allergic rhinitis (3.4%) and urticaria (1.7%). The significantly higher total IgE antibodies concentrations were found in children with allergy-like symptoms (p < 0.0005) (cut-off 15.15 kU/L, sensitivity 76.5% specificity 71.6%). Conclusion. Almost 20% of two-year-old children have any of clinically manifested allergic diseases, with atopic dermatitis and IgE wheeze/asthma being predominant. The higher total IgE antibodies concentration is a good marker for sensitization in children with allergy-like symptoms.

Mindfulness Based Stress Reduction

Introduction: Patients with atopic dermatitis (AD) have several potential stressors including the symptoms of the disease itself, the stigmatization due to their appearance, and emotional and psychological strain. Psychological factors and stress can trigger and exacerbate the symptoms of skin diseases and there is evidence that stress has a relevant clinical effect on the function of skin cells in vivo. Our objective was to evaluate in a pilot study the feasibility, acceptance, and effectiveness of a Mindfulness-Based Stress Reduction (MBSR) programme in AD patients in a clinical setting. Methods: 10 patients took part in an 8-week MBSR programme, which included, e.g., mindful and conscious awareness of the body and bodywork, and seated meditation. We assessed sociodemographics and disease related variables with standardized measures at predefined time points including Score of Atopic Dermatitis, Patient Oriented Eczema Measure, Dermatology Life Quality Index, Perceived Stress Questionnaire, Freiburg Mindfulness Inventory (FMI), and others. Participants also gave qualitative feedback regarding the effects of the intervention. Results: The mean age was 53.10 years (SD = 15.04), seven patients were female, and disease duration was 36.6 years (SD = 25.5). Calculating pre-post effect sizes (Cohen’s d), the FMI indicated significant improvement in the ‘”presence” and ‘”acceptance” subscales. There was also tendency for less stress. This was confirmed by the qualitative statements of the participants. Conclusions: The MBSR programme is feasible and acceptable for AD patients. Considering the long disease history and the severity of disease burden, the effects of this intervention seem promising as an adjunct to conventional treatments for patients with AD.
