Introduction: Elucidation of the primary nature of biochemical shifts in psoriatic disease and prediction of interconnected subsequent changes in metabolic and inflammatory processes are important in foreseeing the dynamic development of pathological process and the choice of individual treatment. The aim of the research was to assess the disorders and correlations between main indicators of protein, fat, hydrocarbon and pigment metabolism and specifics of inflammatory processes in psoriatic patients against the clinical course of dermatosis. Materials and methods: We analysed the results of clinical and laboratory examinations conducted in 62 psoriatic patients. All these patients have been analysed as per their age, sex, prevalence and the type of skin rash as well as per the clinical disease form. Biochemical examinations were conducted using appropriate sets of reagents. To establish the possible correlation between the indicators of biochemical blood analysis, we calculated the correlation coefficient, which determines the nature of correlation between the studied variables. Results: The analysis of results received upon examining psoriatic patients indicated that microbial-viral associations, stress factors and genetic predisposition were the most frequent trigger factors of psoriatic disease, which corresponds to the data from literary sources. We detected that the duration of psoriaric disease up to 5 years was the most common, and relapses were manifested in its limited form against the background of the disease advanced stage; the prevalent psoriasis was more common at the hospital stage. Our study justifies that metabolic changes occurred in the overwhelming majority of examined patients of different age groups. At that, abnormalities of a number of indicators of protein, lipid, hydrocarbon and enzyme metabolism have been established. In addition, the expressiveness of corresponding changes correlated with the prevalence of skin psoriatic process and the duration of dermatosis course as well as the presence of pathology of a number of internal organs, in particular of gastrointestinal tract, hepatobiliary and cardiovascular systems, that suggest the presence of systemic disorders at psoriasis. Conclusions: The identification of independent mechanisms existing between some changes in metabolic process parameters in psoriasis has a theoretical and practical significance in dermatology, which involves the use of medications to regulate the detected disorders, the possibility to restore correlations, and it will inevitably contribute to the achievement of clinical and preventive effect.
The research aim is to identify the correlation between circadian rhythm in terms of changes in the chronotype of human working capacity and severity of psoriasis progression, obesity, and the disease impact on the quality of patients' life. Materials and Methods. The research focuses on the determination of the PASI, BMI, DIAG indexes and a patient's chronotype of working capacity. Results and Discussion. The results of the correlation analysis showed a very high negative correlation between chronotype of patients' working capacity and BMI. They also demonstrated a high negative correlation between PASI and DIAG indicators and chronotype of patients' working capacity. Conclusions. The circadian rhythm changes to the evening chronotype of human working capacity contribute to psoriasis worsening, weight gain, and negative impact of the disease on the quality of patients' life.
Psoriasis is the most common chronic, genetically determined autoimmune polyetiological inflammatory disease with impaired epidermal proliferation, provoked by exogenous and endogenous factors, and manifested by erythematous and scaly elements, papules and plaques. According to the results of clinical and epidemiological studies, psoriasis affects about 3-4% of the population of our planet, regardless of gender, age, and ethnic group, and the specific gravity of this pathology in the general structure of skin diseases reaches, from the data of different authors, from 1% to 40 %. However, despite the significant incidence of psoriasis and a large amount of research on this problem, there is still no single view of the pathogenesis of this dermatosis. For an objective understanding of the pathogenesis of psoriasis, it is necessary to take into account the insufficiently studied comorbidity of this pathology. Therefore, in the studies of the pathogenesis of psoriasis in recent years, more attention is paid to the impairment of metabolic processes. Recently, an indisputable link between psoriasis and obesity has been proven. Obesity has been found to increase the risk of many diseases, including psoriasis. The literature has broadly highlighted the question of the pathogenetic mechanisms of inflammatory processes in psoriasis and obesity that form a vicious circle at the level of the immune system, which must be broken for the successful treatment of these diseases. In this research, we studied the clinical presentation of the disease, measured anthropometric parameters, determined the grade of obesity by BMI, analyzed the history of life and disease, and conducted clinical and biochemical blood tests. The results of the study revealed that alimentary obesity in patients with psoriasis leads to metabolic disorders, complicating the course of dermatosis, which leads to a worsening of the DLQI of patients, the inefficiency of standard methods of therapy and frequent exacerbations of psoriatic disease. Therefore, the prospect for further research is a more in-depth study of the comorbidity of psoriatic disease, which will identify new targets for the treatment of this dermatosis to prevent complications and more effective treatment of this pathology.
