ABSTRACT
Objective:
To verify the effect of ozone on Staphylococcus aureus (S.aureus) colonization in patients with atopic dermatitis (AD) and its correlation with the patient's status.Methods:
A total of 12 patients with moderate or severe AD,aged from 6 to 65 years,were recruited from outpatient of the Third Xiangya Hospital.The treatment sides were showered with ozonated water and smeared with ozonated oil for 7 days (twice a day),while the control sides were washed with warm running water and smeared with base oil.At different time points,the severity scoring ofatopic dermatitis (SCORAD) scores,sleep and pruritus scores were assessed and compared between the two sides.Meanwhile,plate cultivation was used to quantitatively detect the changes ofS.aureus colonization in skin lesions.Results:
After 7 days treatment,erythema and pimples were decreased in the treatment sides.The clear skin texture,smooth skin,improved skin lesions were also observed by dermoscopic examination.The results of reflectance confocal microscopy (RCM) demonstrated that the parakeratosis was improved,the structures were clearer,and the inflammatory cells infiltration was reduced after ozone treatment for 7 days.After ozone treatment for 3 and 7 days,the S.aureus colonization in the treatment sides decreased by (75.55±21.81)% and (97.24±2.64)% respectively.Compared to that of control sides,the percentage of S.aureus colony after ozone treatment for 7 days decreased significantly (P<0.01).After ozone treatment for 7 days,the SCORAD scores,sleep and pruritus scores were significantly decreased (all P<0.01).There was a linear correlation between the decreasing percentage of S.aureus colony and the declining percentage of SCORAD scores in AD patients.Conclusion:
Topical ozone therapy can effectively reduce S.aureus colony in skin lesions and alleviate the severity of AD patients with moderate to severe degree.
