Brief Summary:

With 24 million results associated with Google's searchon keywords "severe acne", Pr Dreno's team understand better thatthis disease, which affects many French people, is a real concern of Public Health and not a "forced evil" of the adolescent period, which will eventually resolve itself. Acne does not affect the vital prognosis, but its psychosocial impact is major and should not be underestimated. Paradoxically, despite the high prevalence of acne, few quality epidemiological studies have been published. Physicians are often helpless when faced with patients' questions. They often need a lot of explanations, especially on the factors aggravating this dermatosis, which greatly affects their quality of life.

This cohort, the first of its kind in France, will determine the predictive factors of therapeutic response, endogenous and environmental factors impacting on the severity of acne assess the quality of life and psychological impact of acne patients, determine the patient's course of care and the associated costs. Pr Dreno's team will also build up a bio collection (bacteriological samples).

Condition or disease Intervention/treatment
Acne Other: acne

Detailed Description:
All patients going for the first time in specialized consultation "acne" at Nantes University Hospital , and who meet the inclusion criteria will be included in the COPACNE cohort. Inclusion will take place at the first consultation, after information and agreement of the patient and, if applicable, his or her legal representatives. The frequency of each patient's follow-up visits will be determined on a case-by-case basis according to the patient's medical needs (generally, the interval between 2 visits is between 1 and 4 months).

  • Other: acne
    Patient with acne
    Other Name: acne vulgaris

Primary Outcome Measures :
  1. Measure of Acne stage [ Time Frame: 2 years ]
    composite criteria. the scale is GEA for Global Evaluation Acne Scale with 0 no acne to 5 severe acne

Secondary Outcome Measures :
  1. assessing patients' quality of life [ Time Frame: 2 years ]
    composite criteria. CADI score is calculated by summing the score of each question resulting in a possible maximum of 15 and a minimum of 0. The higher the score, the more the quality of life is impaired.

  2. cost of acne illness [ Time Frame: 2 years ]
    reimbursement data relating to hospitalizations and care in town recorded by the Health Insurance in the SNIIRAM database.

  3. Bacteriological sample to find Propionibacterium acnes, Hormonal check-up on blood sample [ Time Frame: 2 years ]
    Correlation between bacterial and blood samples and the efficacity of the treatment
