Abstract Background: Post-menopausal women with estrogen receptor positive breast cancer (BC) are typically prescribed endocrine therapy with an aromatase inhibitor (AI) for 5-10 years following BC diagnosis. AIs have multiple established side effects related to estrogen deprivation including vasomotor symptoms, vaginal dryness, and accelerated bone thinning. Many patients also complain about the impact of AIs on skin quality; however, limited data currently exists, particularly with objective measurements of skin quality. Canfield Sciences VISIA-CA is a device that can be used to objectively measure skin changes using patented comparison to norms analysis with a skin feature database to grade the skin relative to others in the same age and skin type. Herein, we aim to evaluate changes in skin quality with the Canfield Sciences VISIA-CA Device after initiation of AI therapy and investigate potential benefits of skincare intervention. Trial Design: This is a pilot study aiming to describe changes in skin quality after initiation of AI therapy in BC survivors through use of VISIA-CA technology and patient reported outcome measures. This study will allow us to collect data and identify the trend (if any) for a future larger study. Patients who consent for participation are given a baseline survey to assess self-reported quality of life, perception of skin quality, and self-image prior to initiation of AI. Patients also receive baseline skin measurement with the VISIA-CA device and facial skin photography. Baseline skincare regimen is documented. Any patients on prescription tretinoin products at time of baseline assessment are excluded from the study. Patients return 6 months after initiation of AI for follow-up surveys, updated VISIA-CA measurement, and facial skin photography. Patients then meet with a Mayo Clinic Cosmetic Center aesthetician for skincare intervention with recommended topical treatments including daily facial cleanser, exfoliator, toner, hydrating crème, and retinol-based product. Patients return for additional visits with updated survey, VISIA-CA measurement, and facial skin photography at 1 month, 3 months, and 6 months after skincare intervention. Patients are asked to complete skincare compliance diary to document adherence on a weekly basis. Eligibility Criteria: Post-menopausal patients with newly diagnosed ER-positive BC at Mayo Clinic Florida are identified for participation in the study prior to beginning AI therapy. Specific Aims: 1.) Evaluate the incidence and severity of skin changes after initiation of AI therapy in BC survivors through use of Canfield Sciences VISIA-CA technology, facial skin photography, and validated patient reported outcome measures. 2.) Assess for objective improvements in skin quality measurements after skincare intervention including a retinol-based product Statistical Methods: Continuous variables will be summarized as mean (standard deviation) or median (range) and categorical variables will be reported as frequency (percentage). The changes of skin measurement and patient reported outcome measurements will be calculated and summarized for the following time frames: 1) from initiation of AI therapy to 26 weeks after 2) from the initiation of skincare intervention and 4 weeks, 12 weeks, and 26 weeks after. Appropriate statistical plots will be used to illustrate the change. Target Accrual: 50 patients.

Background: The presence of various growth factors in platelets makes platelet-rich plasma (PRP) a powerful tool in the stimulation of collagen regeneration in aging skin. The main objective of this study was to determine efficacy and safety of PRP compared with saline solution in women with aging skin of the hands. Methods: In this prospective, randomized clinical trial, 18 women with hand aging received PRP injections every 4 weeks into the unilateral dorsal hand for 12 weeks total; with saline injections into the contralateral hand in a randomized, controlled, single-blind fashion. Physician assessment, photographs, and quality-of-life questionnaires were used for assessment at baseline and at 12-week and 24-week follow-up. Results: The majority of patients reported pain and discomfort along with a burning/stinging sensation in both PRP- and saline-treated hands, with no significant differences noted in any patient outcome measures between the 2 treatments (all P ≥ 0.25). No differences were reliably detected between the treatment hands by a blinded investigator comparing before-and-after clinical photographs of the hands. Conclusions: Three injections of PRP spaced 4 weeks apart did not appear to be effective for treatment of aging skin of the hands in women, with no noted difference as compared with baseline, or saline injection. Although age older than 45 years may be a factor accounting for nonresponse (ie, subtle skin changes are difficult to appreciate, and possible limited platelet regenerative capacity in advanced age), it appears that PRP is not a reliable cosmetic option for management of hand aging. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, II.

AbstractToxic epidermal necrolysis (TEN) is a rare but often lethal drug reaction involving the skin. Treatment is often centered around suppurative care, and the mortality rate remains unacceptably high, although the clinical and epidemiological features of TEN have been well documented for decades. Recent studies have placed an emphasis on certain medications in the pathophysiology of severe TEN, and our colleagues previously reported several cases of clinical improvement in TEN patients following hemodialysis. Here, we discuss the major considerations for initiating dialysis in TEN patients. By doing so, we hope to encourage others to explore this potential avenue for treating TEN, one of the most serious medical emergencies in the field of dermatology.

Abstract Background The pathogenesis of pityriasis rubra pilaris (PRP) is not completely understood, but interleukin (IL)-17 has been shown to play a critical role. There are no reliable immunomodulatory agents to treat PRP. We conducted an open-label, single-arm clinical trial of secukinumab, a monoclonal antibody that inhibits IL-17A, for the treatment of PRP. Objectives To evaluate the clinical efficacy of secukinumab and define the transcriptomic landscape of PRP and its response to IL-17A blockade. Methods Twelve patients with PRP were recruited for an open-label trial of secukinumab. Patients received a 24-week course of secukinumab. The primary endpoint was a ≥ 75% reduction in Psoriasis Area and Severity Index (PASI 75) from baseline to week 28. Secondary endpoints included PASI 90, change in Physician’s Global Assessment (PGA), and change in Dermatology Life Quality Index (DLQI). RNA sequencing was performed on lesional and nonlesional skin biopsies obtained at baseline and week 2. Sample groups were compared to identify differential gene expression and pathway enrichment. This trial was registered with ClinicalTrials.gov: ‘Cosentyx (secukinumab) for the treatment of adult onset pityriasis rubra pilaris’ – NCT03342573. Results At week 28, six of 11 patients (55%) achieved PASI 75, and three patients (27%) achieved PASI 90. PGA (P = 0.008) and DLQI scores (P = 0.010) showed significant improvement with treatment. No serious treatment-related adverse events were encountered. Treatment with secukinumab normalized transcriptional differences between lesional and nonlesional skin. Transcriptomic data from nonresponsive patients suggest that overactivity of innate immune pathways may be driving resistance to secukinumab. Conclusions Secukinumab appears to be an effective treatment for PRP and warrants further investigation. PRP is a transcriptionally heterogeneous disease, reflecting its variable response to therapy. Agents targeting other IL-17 isoforms and innate immune mediators should be considered for future clinical trials. What is already known about this topic? The pathogenesis of pityriasis rubra pilaris is incompletely understood. Successful treatment has been reported with a variety of immunomodulatory agents, but disease is often refractory to therapy.Interleukin (IL)-17 is thought to drive keratinocyte proliferation and vascular dysfunction in this disease.A previous trial demonstrated efficacy of the anti-IL-17A drug ixekizumab for pityriasis rubra pilaris. What does this study add? Herein we describe the findings of a clinical trial of secukinumab, an anti-IL-17A monoclonal antibody, for the treatment of pityriasis rubra pilaris.Secukinumab was effective in treating pityriasis rubra pilaris.Our transcriptomic data give new insight into the expressional changes that occur in response to secukinumab and suggest mechanisms of treatment resistance.

Abstract This study presents a single center experience with livedoid vasculopathy (LV). A rare disease that can lead to severe quality of life impairment. Characterize clinical data of LV patients at the Dermatology Division at the University of São Paulo. A retrospective and transversal study was conducted, from 1 January 2005 to 31 December 2019. About 75 patients diagnosed as LV and confirmed by skin biopsy were included. Epidemiology, clinical appearance, histopathology data, and treatment history were observed. There were 78.66% Caucasian women, with a mean age of 39.9 years. Frequent cutaneous manifestations were ulcers, atrophic blanche‐like scars, hyperpigmentation, purpuras, telangiectasias, and livedo racemosa. Pain, pruritus, and hypoesthesia were the main symptoms. After treatment, almost 40% of cases relapsed during spring and summer months. About 66% of cases had thrombophilia factors associated, such as high levels of lipoprotein(a). Frequent treatments included acetylsalicylic acid, pentoxifylline, and diosmin with hesperidin. Not being a prospective study. This research provides useful data on Latin American LV patients, indicating multifactorial conditions involved in LV pathogenesis. An extensive work‐up including autoimmune laboratory tests, thrombophilia factors, and other conditions associated with venous stasis should be part of LV investigation and controlled to improve treatment response.
