Teledermatology vs. Face-to-Face Visits in the Follow-Up of Patients With Acne

Acne vulgaris is a common cutaneous inflammatory condition of sebaceous follicles that can profoundly affect patients' quality of life, especially at a young age. In this context the use of teledermatology can potentially reduce the healthcare costs associated to traditional consultations as well as the costs related to travel and loss of school/working time for the patient, with a clear benefit for the whole community. Since 2016, the Department of Dermatology at Inselspital Hospital in Bern has a portal and a smartphone app for online advice service. Hereby the investigators propose to explicitly investigate the efficacy of this system in reducing healthcare costs as compared to traditional face-to-face consultations, in a cohort of patients with mild-to-moderate acne vulgaris.

Randomized Double-blind Study on the Benefit of Spironolactone for Treating Acne of Adult Woman.

Acne vulgaris of adult woman has increased over the past 10 years; it affects currently 20% to 30% of adult women. The physiopathology of adult woman acne is distinguished from the teenager one by essentially 2 factors: hormonal factor with a peripheral hyperandrogenism coupled with an hypersensibility of cutaneous androgens receptors of these women. But this point is still at the stage of hypothesis. inflammatory factor linked with Propionibacterium Aces ; indeed these women received most of the time many cures of local and systematic antibiotics at the origin of resistant Propionibacterium Aces strains which lead to a chronical activation of cutaneous innate immunity. On a therapeutic plan, four types of systemic treatment, approved in this indication are: Tetracyclines which are problematic for the bacterial resistance and consequently constant relapse when they are stopped. Zinc salts which target only the inflammatory lesions and were shown less effective than cycline Antiandrogens, with acetate of cyproterone associated with risks of phlebitis and pulmonary embolism, and increase risk of triglycerides, cholesterol and hepatic balance. The last alternative is represented by isotretinoin but the use in women of childbearing potential is binding because of the teratogen risks and the hyperandrogenism represents an identified risk of relapse. In this context, the spironolactone could represent an interesting alternative. It blocks the 5-alpha-reductase receptors at sebaceous gland and inhibits Luteinizing hormone (LH) production at the pituitary level. It is not submitted to isotretinoin constraints, does not lead to bacterial resistance and targets the peripheral hyperandrogenism. Currently, very few studies have been performed and on a weak number of patients but they showed that at low doses (lower than 200mg/day), spironolactone can be effective against acne. In that context, it seemed clearly interesting to perform the first double-blind randomized study spironolactone vs cyclines which remains the moderate acne reference treatment and to demonstrate the superiority of spironolactone's efficacy in order to establish it as alternative way to cycline.

Inflammatory Cells From Various Pathologies

The objective of this experiment is to develop and validate in vitro methods to isolate inflammatory cells from skin biopsies for quantitative flow cytometry analysis. Real-time polymerase chain reaction (RT-PCR) will also be performed using skin biopsy samples to validate flow cytometry results. Such methods could eventually be used to better understand the pathophysiology and the mechanism of action of various medications in patients with atopic dermatitis, acne rosacea or vulgaris, HS, and systemic sclerosis. In this study, up to 15 healthy volunteers, 50 patients with atopic dermatitis, 15 patients with acne rosacea, 15 patients with psoriasis (to be used as control), 15 patients with acne vulgaris, 10 patients with psoriasis to develop a method of analysis for systemic sclerosis, and 10 patients with HS will be recruited. For the healthy volunteers, atopic dermatitis, psoriasis and HS groups, at least one (1) and a maximum of four (4) skin biopsies (4-5 mm) per subject will be performed. Biopsies will be performed on either the trunk or the limbs, excluding the hands and the feet. At least one (1) and a maximum of three (3) skin biopsies (2-3 mm) per subject will be collected for the acne rosacea and acne vulgaris groups from one or more body location(s) affected by the pathology. For patients with atopic dermatitis, an optional blood draw of up to 10 mL will be collected to measure serum IgE levels. For patients with atopic dermatitis, psoriasis, and HS, an optional blood collection of up to 50 mL will be collected to perform flow cytometry on circulating blood cells to study differences in flow cytometry results between cells extracted from biopsies and circulating cells.

Evaluation of the Presence of Enthesitis in Patients With Acne Vulgaris

Acne vulgaris is an inflammatory disease of the pilosebaceous unit, affecting about 85% of the young population. In the studies p. acne is a potent stimulator of the release of IFN-gamma (IFN-)) and IL-17 from CD4 + T cells, and the presence of IL-17 + cells in the perifollicular infiltrate has been shown in biopsies of inflammatory acne lesions. Therefore, acne is thought to be a Th17-related disease (1). This study was aimed to evaluate the presence of enthesitis in patients with acne vulgaris.

Start: February 2020

Trial of Single Microneedle Radiofrequency for Moderate-to-Severe Acne Vulgaris

The purpose of the study is to testify the efficacy of treating moderate-to-severe acne vulgaris with Single Microneedle Radiofrequency, and provide evidence for the hypothesis that "whether Single Microneedle Radiofrequency therapy could be an alternative to photodynamic therapy for moderate to severe acne vulgaris."

Start: November 2019

Multimodal Optical Imaging for Pretreatment Evaluation for Cutaneous Microparticle Delivery

The purpose of this study is to investigate how pretreatment with a topical medication for acne affects application and delivery of gold microparticles to the skin in acne patients. In addition, the investigators want to investigate the biodistribution of gold microparticles in pretreated skin and compare this with the biodistribution of untreated skin using the non-invasive imaging techniques optical coherence tomography and reflectance confocal microscopy
