Acne in adult females is triggered mainly by hormones. Doxycycline is a reference treatment in acne. Spironolactone targets the androgen receptor of sebaceous glands and is prescribed off-label for female adult acne. This multicentre, controlled, randomized, double-blind prospective and parallel study assessed the efficacy of spironolactone compared with doxycycline in adult female acne. A total of 133 women with moderate acne were randomized to receive treatment with: (i) doxycycline and benzoyl peroxide for 3 months followed by a 3-month treatment with its placebo and benzoyl peroxide, or (ii) spironolactone and benzoyl peroxide for 6 months. Successfully treated patients continued with benzoyl peroxide or spironolactone alone for a further 6 months. Primary endpoints were treatment success at month 4 and month 6 with the AFAST score. At all visits, the ECLA score, lesion counts, local and systemic safety and quality of life were assessed. Spironolactone performed better at month 4 and showed a statistically significant better treatment success after 6 months than doxycycline (p = 0.007). Spironolactone was 1.37-times and 2.87-times more successful compared with doxycycline at respective time-points. AFAST and ECLA scores, as well as lesion counts always improved more with spironolactone. Patients' quality of life was better with spironolactone at month 4 and month 6. Spironolactone was very well tolerated. This is the first study to show that, in female adults with moderate acne, treatment with spironolactone is significantly more successful than doxycycline and very well tolerated.

In France, hospital cell therapy units have not been authorised to routinely produce chimeric antigen receptor T lymphocytes (CAR-T cells), which would then be referred to as academic CAR-T cells. CAR-T cells are classified as advanced therapy medicinal products and correspond to genetically modified T lymphocytes ex vivo. The CAR-T cell production process is complex and requires scientific and technical expertise to meet the acceptance criteria of the pharmaceutical quality system. The most commonly used method for genetically modifying T lymphocytes is viral transduction (lentiviral or retroviral), which requires prior access to a batch of good manufacturing practice (GMP) grade viral vector. Because of its cost, this reagent is the main limiting factor for developing CAR-T cells. A CAR-T cell produced by an industrial company is expensive (around €350,000 per injection) and the time taken by the manufacturer to make it available to the clinician can vary from three to five weeks. By meeting the economic and ecological challenges, can academic structures improve access to CAR-T cells? In this article, we present the elements necessary for the feasibility of setting up CAR-T cell production in an academic structure., (Copyright © 2023 Société Française du Cancer.

Background: Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease of the follicles in the apocrine glands and is associated with a deficiency in the innate immunity of the skin. It is characterized by the occurrence of nodules, abscesses, fistulas, scars., Objective: Although a relationship has already been demonstrated between HS and innate immunity, IGF-1 status in patients with HS is still unknown. The objective of this pilot study was to determine IGF-1 status in patients with HS as well as its potential relationship with the clinical profile of the disease., Methods: This monocentric and cross-sectional study involved 39 patients hospitalized at the Dermatology Department of CHU Nantes between November 2014 and January 2018. Clinical data and IGF1 status were collected during the follow-up consultation., Results: Forty-nine percent of the patients had very low levels of IGF-1. At the clinical level, these patients were young and with a short duration of disease. The major difference was that IGF1-deficient patients had a higher BMI than others. The others factors differing between the two patient groups did not reach statistical significance., Conclusion: This exploratory pilot study indicates that HS with a low level of IGF-1 could represent a specific phenotype of patients with HS. These preliminary results have to be confirmed with a larger cohort, as they could have practical consequences in the therapeutic care of these patients.
