Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Increase of serum levels of IL-10 and decrease of IL-17, as well as their quantitative skin expression evaluated by immunohistochemistry and digital analysis in inflammatory lesion and perilesional area. Similar expression in perilesional and inflammatory area will corroborate to the hypothesis that inflammation occurs prior to the development of clinical lesions. The treatment modulation of IL-10 and IL-17 will be considered as success. | — |
Secondary
| Measure | Time frame |
|---|---|
| Improvement or complete clearance (this will be difficult as patients will receive monotherapy) of skin lesions and overall appearance of skin, through count of inflammatory lesions by the investigaror (on a 4-point scale: 0 = complete improvement, 1 = partial improvement, 2 = unchanged, 3 = worsening); general appearance of the skin by the investigator, the research participants and two independent observers, and photographic evaluation. ;Increasing Acne-QoL-BR scores by re-applying the questionnaire after treatment will be considered a success (total score ranges from 0 to 114 and higher scores reflect better health-related quality of life).;Demonstration of the possible correlation between acne and metabolic syndrome, measurement of abdominal circumference, blood pressure, weight, height and body mass index -BMI, and laboratory tests (glucose, blood cell count, cholesterol and fractions, triglycerides, ALT, AST, alkaline phosphatase, gamma glutamyl transferase, urea, creatinine, insulin, HOMA-IR). | — |
