Microbial eczema (ME) is a chronic infectious dermatosis that develops in response to microbial and/or fungal antigenic stimulation. Cold atmospheric plasma (CAP) has a bactericidal effect on microbial cells, viruses and fungi and activates the processes of regeneration of damaged surfaces which allowed to include it in the ME therapy.
OBJECTIVE
Effectiveness evaluation of various ME therapy methods in children.
MATERIAL AND METHODS
The study included 108 patients aged 1 to 13 years (median age 7 years) divided into 3 groups. Group 1 included 20 patients aged 1 to 13 years (median age 8 years) who received external therapy with a combined drug (topical steroid + antibiotic + antimycotic; pimafucort) in combination with a 1st generation antihistamine (suprastin at an age-specific dose) + sedative (antipruritic) agent for 14 days. Group 2 consisted of 49 patients aged 1 to 13 years (median age 6 years) who received therapy similar to that in group 1 in combination with laser therapy (5 sessions). Group 3 included 39 children aged 2 to 13 years (median age 7 years) who received therapy similar to patients in group 1 in combination with treatment of lesions with CAP (5 sessions). The severity of ME was assessed using the ME severity index, the efficacy was assessed by clinical criteria. The efficacy assessment also includes an analysis of the number of relapses during the next one-year follow-up.
RESULTS
The intensity of itching decreased by 50% or more in group 1 by the 6th day, in group 2 by the 4th day, in group 3 by the 2nd day of therapy; complete relief of itching was achieved by 10th, 7th and 3rd days depending on therapy accordingly. In group 1 the complete relief of ME was achieved only in 5% of patients, significant improvement — in 30%, in group 2 — in 6 and 51%, respectively, in group 3 — in 67% and 33% of children. On average, 2.5 months passed before the next recurrence of ME in group 1, 4.5 months in group 2, and 8 months in group 3. The average length of hospitalization for a patient with moderate/severe ME was 14.6, 10.2, and 6.2 days, respectively.
CONCLUSION
The inclusion of CAP into ME therapy in children and adolescents made it possible to lengthen the period of remission by 3.2 times.
