Current prescribing for pyoderma gangrenosum in the UK and access to biologic medications: Results from a UK Dermatology Clinical Trials Network (UKDCTN) survey of UK Dermatologists.

Pyoderma gangrenosum (PG) is an ulcerative inflammatory disorder affecting the lower legs in 80% of cases. The use of biologic medications to treat PG is increasing although there is a limited evidence base to guide treatment choices. In some health systems, such as the UK NHS, limitations are placed on biologic prescribing for PG leading to wide variations in prescribing. A survey of mainly UK clinicians showed that prednisolone remains the first line treatment for PG (90%). Biologics have been used by 66% of clinicians as second line therapy but 19% have had prescribing requests declined. Further research is needed to determine optimal treatment strategies for PG.

How is oral isotretinoin prescribed for the treatment of acne vulgaris? Results from a UK Dermatology Clinical Trials Network (UKDCTN) and British Dermatological Nursing Group (BDNG) survey of health professionals.

We undertook a survey of UK healthcare professionals through the UK Dermatology Clinical Trials Network and British Dermatological Nursing Group to understand clinicians' routine practice of prescribing oral isotretinoin for treatment of acne vulgaris. We also wanted to understand clinicians' experiences and views on prescribing low daily dose regimens. Overall, the survey showed that clinicians adopted a patient-centred approach when deciding isotretinoin dosing. The rationale for using a low-dose regimen varied, but was focused on patient wellbeing during treatment. Some clinicians were concerned that use of a low-dose regimen could be less effective and lead to longer treatment durations. The survey results will be useful to inform a clinical trial investigating the effectiveness and safety of low daily dose isotretinoin for the treatment of acne.

Celebrating 20 years of the UK Dermatology Clinical Trials Network. Part 1: Developing and delivering high-quality independent clinical trials.

The UK Dermatology Clinical Trials Network (UK DCTN) was formed in 2002 with the aim of developing and supporting high-quality independent national clinical trials that address prioritized research questions for people with skin disease. Its philosophy is to democratize UK dermatological clinical research and to tackle important clinical questions that industry has no incentive to answer. The network also plays a key role in training and capacity development. Its membership of over 1000 individuals includes dermatology consultants, trainees, dermatology nurses, general practitioners, methodologists and patients. Its organizational structures are lean and include a co-ordinating team based at the Centre of Evidence-Based Dermatology in Nottingham, and an executive with independent members to ensure probity and business progression. A prioritization panel and steering group enable a pipeline of projects to be prioritized and refined for external funding from independent sources. The UK DCTN has supported and completed 12 national clinical trials, attracting investment of over £15 million into UK clinical dermatology research. Trials have covered a range of interventions from drugs such as doxycycline (BLISTER), silk clothing for eczema (CLOTHES) and surgical interventions for hidradenitis suppurativa (THESEUS). Trial results are published in prestigious journals and have global impact. Genuine partnership with patients and carers has been a strong feature of the network since its inception. The UK DCTN is proud of its first 20 years of collaborative work, and aims to remain at the forefront of independent dermatological health technology assessment, as well as expanding into areas including diagnostics, artificial intelligence, efficient studies and innovative designs.

Setting research priorities for management and treatment of hyperhidrosis: the results of the James Lind Alliance Priority Setting Partnership.

BACKGROUND: Hyperhidrosis is a common skin condition characterized by excessive sweating, which can negatively impact on quality of life. It is under-researched compared with other conditions of similar prevalence. AIM: To generate a Top 10 list of research priorities for the treatment and management of hyperhidrosis, with equal input from people with hyperhidrosis and healthcare professionals (HCPs). METHODS: A priority setting partnership (PSP) was established and processes from the James Lind Alliance Handbook were followed. An online survey asked participants what questions they would like research to answer. These questions were grouped into 'indicative questions', which were ranked in a second survey of 45 indicative questions. The top 23 questions were then taken to a final workshop event attended by key stakeholders, and ranked to generate the Top 10 list of research priorities. RESULTS: There were 592 questions submitted by 268 respondents for the first survey. For the second survey, 286 participants ranked the indicative questions in order of priority. At the final workshop, the Top 10 list was generated. The top three priorities were: (i) Are there any safe and effective permanent solutions for hyperhidrosis? (ii) What is the most effective and safe oral treatment (drugs taken by mouth) for hyperhidrosis? and (iii) What are the most effective and safe ways to reduce sweating in particular areas of the body? CONCLUSIONS: There are many unanswered research questions that both people with hyperhidrosis and HCPs would like to see answered. The results from this PSP will help to ensure future research funding can be directed to these areas of priority.
