RESUMEN
INTRODUCTION: Acne remains one of the most common inflammatory dermatoses seen worldwide. There are significant challenges when managing acne relating to a variety of factors, including (1) lack of consensus on the use of the numerous available grading systems and outcome measures, (2) appreciation of the numerous areas that relate to severity, (3) the chronic nature of acne which requires a longitudinal approach to management (including both facial and truncal disease), and (4) the need to target acne early to avoid physical and psychosocial scarring. Consideration of these aspects when managing acne should result in improved outcomes. Acne guidelines review the available evidence based on robust clinical trials and are usually supplemented with some expert opinion when evidence is not available. METHODS: In this paper, the UK Acne Working Group reflects on the latest National Institute for Health and Care Excellence (NICE) acne guidelines with a goal of providing additional practical insights. CONCLUSION: The group have identified areas where new evidence has now become available since the formulation of the NICE acne guidelines. This publication considers newly approved acne medications in the UK, guidance on assessing acne severity, approaches to managing truncal acne, acne sequelae, and adult female acne with hormonal therapies.
The National Institute for Health and Care Excellence (NICE) produced acne guidelines in June 2021 for clinicians and patients. New evidence and information on practical aspects of acne management have emerged since this time. A panel of clinicians with expertise in acne discuss herein some areas of interest that may support acne management, some of which could be considered in a second iteration of NICE acne guidelines. These areas include how to assess acne, the medical approach to truncal acne, how clinicians may manage the long-lasting acne sequelae of scarring and darkly pigmented spots, and the use of medical hormonal therapies for women (such as birth control pills) to manage acne that may have a causative contribution of hormone imbalances.
RESUMEN
Two patients with a long-standing history of recalcitrant ankylosing spondylitis were commenced on adalimumab as monotherapy. Case 1 developed marked rapid deterioration in his previously stable vitiligo within 3 months of commencing treatment. This was attributed to anti-tumor necrosis factor (TNF) therapy, and a marked improvement was noted following withdrawal of adalimumab. Case 2 developed multiple new halo naevi over the trunk and limbs. They did not show dysplastic features and have remained unchanged despite continuation of treatment. Possible mechanisms and implications of the paradoxical occurrence of immune-mediated skin lesions seen in patients receiving anti-TNF therapies are discussed.
