spp. as a possible aetiopathogenic factor of acne and relation with acne severity and type.

INTRODUCTION

Acne is a very common skin disease in adolescents and young adults, but it also affects adults. However, its aetiology is not yet fully understood. appears to be associated with multiple skin disorders, but controversy persists. Some reports indicate a connection between acne vulgaris and demodicosis.

AIM

To confirm the association between infestation and acne vulgaris.

MATERIAL AND METHODS

A total of 108 patients were enrolled in the acne group. Acne severity was calculated as GASS and acne type (adolescent and post adolescent) was recorded. An age-sex matched healthy control group comprising 65 individuals were included in the study. Dermatological examinations were performed and an SSSB was used to determine the presence of .

RESULTS

In our study, positivity was seen in 46 (42.6%) patients in the acne group and 8 (12.3%) in the control group; this difference was statistically significant ( < 0.001). A multivariate Backward Step-By-Step Logistic Regression analysis identified the most effective factors for acne development such as positivity ( = 5.565, 95% CI: 2.384-12.99 and < 0.001) and age under 25 years ( = 2.3 and 95% CI: 1.183-4.473 and = 0.014). Alcohol consumption was related to positivity ( = 0.019) in post adolescent acne.

CONCLUSIONS

Our study is the first one to evaluate acne severity, acne type and the relationship to prevalence. We suggest that infestation should be considered when the classical therapies are ineffective especially in cases of post adolescent acne.
