The infectious nature of the process in microbial eczema or complications of bacterial infection of true eczema indicates an impairment in the immune system, especially innate immunity. Primary pathogen receptors, the complement system, phagocytosis, interferons, and endogenous antibiotic peptides play a crucial role in the body's innate defense. The first line of defense is provided by antimicrobial peptides, which are non−specific factors of humoral immunity, and have endotoxin−neutralizing and immune modulatory activity, as well as act against a wide range of microorganisms. One of them is defensins, which are cationic amphipathic peptides with a length of 30 to 42 amino acids with a three−stranded β−plate structure containing three disulfide bonds. The main producers of human β−defensins (Human Beta Defensin) are various epithelial cells, including keratinocytes. Defensins have antibacterial, antiviral, antifungal and antiparasitic effects. β−defensins are active against gram−positive and gram−negative bacteria, in addition, they exhibit anti−yeast activity. In patients, the severity of dermatosis was determined based on the calculation of EASI (Eczema Area Severity Index), the content of Human Beta Defensin was done with enzyme−linked immunosorbent assay, in the serum of patients with chronic eczema, it was increased 15.9 times compared to the control group. Quantitative levels of Human Beta Defensin 2 have been shown to be closely related to the disease severity. The content of Human Beta Defensin 2 in the serum of patients with chronic eczema may be a marker of the dermatosis severity.
Key words: chronic eczema, true and microbial eczema, pathogenesis, β−defensin, severity.
Significant correlations were between the remote functional outcome and the following predictors: the severity of injury at admission (r=0.527; p<0,01), leukocyte level at admission (r=0.594; p<0,01), presence and severity of pelvic disturbances (r=0.574; p<0,01), the duration of staying in intensive care (r=0.476; p<0,01), neurological deficit severity and scores on the Glasgow Outcome Scale (r=0.469; p<0,01). Character of remote outcome was associated with posttraumatic amnesia (r=0.491; p<0,05), concomitant injuries of abdominal cavity organs, kidney, bladder, time of starting peroral feeding (r=0.377; p<0,05), mean heart rhythm rate during the first 14 days of treatment, pneumonia (r=0.377; p<0,05) and episodes of psychomotor agitation (r=0.381; p<0,05) within a period of hospital treatment. These results need confirmation in a larger study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
