Study of polymorphic genes of pro- and anti-inflammatory cytokines (IL-4, IL-10, TNF-α) in patients with occupational allergic dermatoses showed significantly higher frequency of polymorphic variants of cytokine genes IL4 C589T, IL10 C819T, IL10 G1082A, IL10 C592A, and TNF G308A in comparison with the population control. The presence of homozygous variant IL10 G1082A--AA in 80% cases characterizes early disease development, i.e. within 3 years after the first exposure to the occupational factor.
This review presents literature data on the role of the gastric tract in the processes of intoxication and detoxification of endoand exobiotics. The factors that promote the absorption and metabolism of toxic products in the gastrointestinal tract are described. The causes of intoxication and the mechanisms of two-phase detoxification with the participation of phase I enzymes of the biotransformation of xenobiotics in the intestine, in particular cytochrome P-450 isoenzymes, are described in detail. The predominance of the cytochrome P-450 isoenzyme CYP3A4 in the intestine was shown, and among the enzymes of phase II of biotransformation in the intestinal wall, the most important are UDP-glucuronyltransferase and sulfotransferase. The data on the ways of correction of intoxication with the use of a detoxification complex of dietary nutrition are presented. Clinical studies have shown that a specialized program provides antioxidant protection and the work of enzymes of the I and II stages of the metabolism of toxins, a decrease in the absorption and excretion of metabolic products, can significantly reduce the intoxication of the body, which is extremely necessary during the treatment and rehabilitation of diseases of the gastrointestinal tract and other organs and systems. rehabilitation of the body. It was found that the use of products of detox nutritional program LEOVIT DETOX led to a significant decrease in the concentration of urea and creatinine, which indicates an accelerated elimination of toxins and metabolic products formed in the body. A decrease in the concentration in the blood of the main enzymes characterizing the detoxification activity of the liver ALT, AST, GGT was also established.The aim of the study was to evaluate the detoxification effectiveness of the preventive nutrition Program and individual detoxification products LEOVIT DETOX, designed to affect all stages of Exo — and endobiotic metabolism.Materials and methods. Detoxification nutrition LEOVIT DETOX includes: specialized food product of dietary preventive nutrition “Complex nutrition program DETOX”, detoxifying jelly and bars — specialized food products of dietary preventive nutrition for detoxification of the body. The DETOX nutrition program is designed for 15 days and contains 30 products. The dynamics of biochemical parameters of liver and kidney function disorders (AST, ALT, GGT, urea, creatinine), blood lipid spectrum (by total cholesterol), fasting blood glucose level, and products of lipid peroxidation in blood serum were measured.Results. The use of specialized food products of dietary prophylactic nutrition “, a Comprehensive nutrition program DETOX” leads to a significant decrease in the concentration of urea and creatinine, AST, ALT, GGT, cholesterol, glucose, diene conjugate, ketodienes of CARBONYLS and increased total oxidative activity of blood serum were examined.Conclusion. The use of a specialized food product of dietary preventive nutrition “Complex nutrition program DETOX” provides effective detoxification of the body in diseases of the gastro-intestinal system.
Introduction. Health care workers are at risk of infection with the SARS-CoV-2 virus. However, many aspects of the professionally conditioned COVID-19 are still poorly understood. The aim of study is to conduct a brief review and analysis of scientific data on the prevalence, features of clinical and laboratory COVID-19 syndromes in medical professionals. To evaluate the structure of post-COVID syndrome in health care workers who are observed in a large multidisciplinary medical organization that has a center for occupational pathology. To present the current state of the problem of examination of the connection of COVID-19 with the profession and admission to work in conditions of high risk of SARS-CoV-2 infection. Materials and methods. At the first stage, a brief review of the literature on the problem of COVID-19 in health care workers was performed, at the second - a single-center observational prospective study of COVID-19 convalescents. The main group consisted of health care workers (n=203), the comparison group - people who do not have occupational health risks (n=156). The groups were comparable in demographic characteristics. The work experience of the medical staff was 15 (5; 21) years. Of the participants in the main group, 20.2% worked in hospitals, and 79.8% in outpatient institutions. Three of the participants (1.5%) were employees of specialized COVID hospitals. Doctors were 25.6%, secondary medical personnel - 51.7%, junior medical and technical personnel - 22.7%. A severe form of COVID-19 was suffered by 25 (12.3%) people, after the artificial ventilation of the lungs (AVL) - two participants. The observation time is 60 days. Statistical analysis included standard methods of descriptive statistics, determination of relationships by the method of logistic regression. The significance level is p<0.05. Results. Most of the known data on COVID-19 in health care workers is obtained in cross-sectional studies. The possibility of occupational infection has been sufficiently proven. The risk probably depends on the work performed and is higher in conditions of direct contact of medical personnel with adults, potentially infected patients, but not in a specialized hospital. It is possible that the course of COVID-19 in health care workers differs from the general population of patients there is evidence of a greater frequency of weakness and myalgia. Studies of the features of post-COVID syndrome in health care workers in available sources could not be identified. According to the results of their own research, health care workers who had experienced COVID-19 had a higher frequency of central thermoregulation disorders, arrhythmias, heart failure, panic attacks and depression. Conclusions. Health care workers are at risk of COVID-19. Professionally conditioned post-COVID syndrome is characterized by the frequency of violations of the central mechanisms of thermoregulation and arrhythmias. COVID-19 in health care workers meets the definition of occupational disease.
Over the past decades, the world has seen an increase in occupational lung diseases, the leaders being asthma and chronic obstructive pulmonary disease (COPD). The article presents the results of 5-year observation of food industry workers. Clinical functional and molecular genetic studies have been carried out to identify the frequency and severity of asthma and COPD along with the individual predisposition to pulmonary conditions.Methods. 76 people of both sexes with the average age of 43.5 ± 3.6 years were examined on an outpatient basis. All subjects had daily contact with toxic and allergenic aerosols and organo-mineral dust. The respiratory function and the presence of bronchial hyperresponsiveness to occupational factors was assessed by spirography and peak flowmetry in response to exposure and elimination of industrial aerosols. Immunological and molecular genetic tests were performed: identification of hyposecretory alleles of the α1 -АТ gene, determination of polymorphisms of the GSTM1 and GSTT1 genes, immunoglobulin levels (IgE, IgM, IgG) and cytokine status (IL-4, -6, -8; TNF-α).Results. During the 5-year follow-up period, there was a significant increase in the number of employees with severe respiratory symptoms – 36.8% (95% CI – 21.2–36.8; p < 0.05) and a statistically significant decrease in the respiratory function (p < 0.001). Progressive decrease in the respiratory function in healthy individuals and the appearance of new and more severe cases of asthma and COPD were registered primarily among workers with hyposecretory alleles of the α1 -АТ gene and/or zero alleles of the glutathioneS-transferase genes (GSTM1 and GSTT1) in combination with abnormal cytokine status.Conclusion. Individual risk factors for the development of asthma and COPD in individuals working in contact with toxic and allergenic aerosols and organo-mineral dust are hyposecretory PiMZ variant of the α1 -АТ gene and deletions in the glutathione-S-transferase genes (GSTM1 0/0 and GSTT1 0/0) in combination with abnormal cytokine status. Long-term research results suggest the prognostic value of assessing individual sensitivity to industrial aerosols and the development of bronchopulmonary pathology.
