Treatment of moderate-to-severe psoriasis in adults: An expert consensus statement using a Delphi method to produce a decision-making algorithm.

BACKGROUND: New highly effective drugs for moderate-to-severe cutaneous psoriasis are regularly marketed, and the hierarchy of treatments thus requires frequent review. OBJECTIVES: A Delphi method was used to enable a structured expert consensus on the use of systemic treatments and phototherapy among adults with moderate-to-severe psoriasis. METHODS: The Delphi method consists in achieving a convergence of opinions among a panel of experts using several rounds of questionnaires with controlled feedback between rounds. A two-part Delphi questionnaire was administered online to French psoriasis experts. In the first part, 180 items related to the prescription of systemic treatments and phototherapy for adult patients with moderate-to-severe psoriasis were grouped into 21 sections covering different lines of treatment and different forms of cutaneous psoriasis. The experts voted on each proposal using an ordinal 7-point Likert scale. The second part comprised 11 open-ended questions about special indications for each therapeutic class. These were converted into 101 questions for subsequent rounds. Consensus was deemed to have been reached if more than 80% of the experts agreed with a given proposal. RESULTS: Three rounds of questionnaires were sequentially sent to 35 participants between November 2021 and March 2022. Thirty-three (94%) completed all three rounds. For plaque psoriasis, only methotrexate was recommended by the experts as first-line systemic treatment (89% of votes). Cyclosporin was advocated in pustular and erythrodermic psoriasis, and acitretin was suggested for hyperkeratotic and palmoplantar psoriasis. In the event of failure of or intolerance to non-biological systemic treatments, guselkumab, risankizumab, ixekizumab or secukinumab were recommended by more than 80% of the experts. Tumor Necrosis Factor (TNF) inhibitors remain useful for patients with cardiovascular risk factors. Special indications were provided for each therapeutic class (methotrexate/narrowband ultraviolet B phototherapy, psoralen/ultraviolet A phototherapy, cyclosporin, acitretin, apremilast, TNF inhibitors, interleukin (IL)-12/23 inhibitors, IL-17(R)A inhibitors, and IL-23 inhibitors). CONCLUSIONS: This expert consensus statement indicate that newly available IL-17 and IL-23 inhibitors may be favored over TNF and IL-12/23 inhibitors as first-line biologics. The Centre of Evidence of the French Society of Dermatology has drawn up a decision-making algorithm to guide clinicians in the therapeutic management of moderate-to-severe psoriasis.

Healthcare transition from childhood to adulthood in pseudoxanthoma elasticum: Patient experience and recommendations for health practitioners.

PURPOSE: Health-care transition (HCT) is a necessary part of the care process for allsick adolescents, to allow their empowerment while limiting disruption to follow-up care. Pseudoxanthoma elasticum (PXE) runs the risk of losing patients to follow-up because young patients are predominantly asymptomatic. This can be detrimental as it can prevent primary prevention measures from being properly implemented. The purpose of this study was to assess satisfaction of PXE patients with their health-care transition and to identify the factors associated with its success, in order to improve care management in young PXE patients. METHODS: Patients aged 22 to 40 years diagnosed with PXE before the age of 16 years were included from the cohort of patients followed at Angers University Hospital. They were sent a questionnaire for the purposes of collecting data on medical management during adolescence, transition and adulthood. RESULTS: Eleven responses were obtained from the 21 patients surveyed. The median satisfaction score of PXE patients regarding their transition was 5/10. Three patients reported having discontinued follow-up after transition. In adulthood, the majority of the participants were followed up by 4 specialists as recommended. It was incumbent on 50% of the patients who changed doctors to provide details of their own medical history to the new practitioner. CONCLUSION: Better intra-practitioner communication and a chart summarizing the principles of primary prevention, optimal follow-up care and its frequency are simple to implement and in all likelihood result in better health-care transition for young PXE patients.

Acute acral eruptions in children during the COVID-19 pandemic: Characteristics of 103 children and their family clusters.

BACKGROUND: A marked increase in frequency of acute acral eruptions (AAE) was observed in children during the COVID-19 pandemic in the spring period. OBJECTIVES: In this observational multicenter study, based on children with AAE, we aimed to assess the proportion of household members possibly infected by SARS-CoV-2. METHODS: We collected data from all children observed with AAE, prospectively from April 7, 2020 to June 22, 2020, and retrospectively since February 28, 2020. The primary outcome was the household infection rate, defined as the proportion of family clusters having at least one member with COVID-19 infection other than the child with AAE ("index child"). The definition of a case was based on characteristic clinical signs and a positive PCR or serology. RESULTS: The study included 103 children in 10 French departments and in Quebec. The median age was 13 years and the interquartile range [8-15], with a female-to-male ratio of 1/1.15. In children with AAE, all PCR tests were negative (n=18), and serology was positive in 2/14 (14.3%) cases. We found no significant anomalies in the lab results. A total of 66 of the 103 families (64.1%) of included children had at least one other infected member apart from the index child. The total number of household members was 292, of whom 119 (40.8%) were considered possibly infected by SARS-CoV-2. No index children or households exhibited severe COVID-19. DISCUSSION: Among the 103 households included, 64.1% had at least one infected member. Neither children with AAE nor their households showed severe COVID-19.

Topical rapamycin versus betamethasone dipropionate ointment for treating oral erosive lichen planus: a randomized, double-blind, controlled study.

BACKGROUND: Although superpotent topical corticosteroids are the first-line treatment for oral erosive lichen planus (OELP), topical rapamycin was found efficient in a previous case series. OBJECTIVES: To compare the efficacy and safety of topical rapamycin and betamethasone dipropionate ointment for OELP in a randomized, double-blind trial. METHODS: Patients were randomized to receive treatment with betamethasone dipropionate ointment 0.05% in Orabase® or topical rapamycin solution (1 mg/mL) on lesions twice daily for 3 months, followed by 3 months of observation. The primary outcome was clinical remission after 3 months of treatment. Secondary outcomes were clinical remission after 1 and 2 months, reduced oral pain and reduced impact on food intake after 3 months, clinical recurrence after treatment withdrawal, and adverse events. RESULTS: During a 4-year period, 76 patients were randomized and 75 received treatment (rapamycin, n = 39; betamethasone, n = 36). At 3 months, 39.4% of patients with betamethasone and 27.3% with rapamycin showed clinical remission (odds ratio 0.68, 95% CI [0.24; 1.89]; P = 0.46). Rates of remission after 1 and 2 months, reduction in pain and impact on food intake after 3 months, were higher with betamethasone than rapamycin. Recurrence of oral erosions was similar between groups. Adverse events occurred in 43.6% of patients with rapamycin (mostly burning sensation, impaired taste) and 27.8% with betamethasone (mostly oral candidiasis). CONCLUSION: Although the study was limited by insufficient recruitment, we did not find any superiority of topical rapamycin over betamethasone dipropionate ointment for OELP. Given the rapid remission and pain improvement in the betamethasone group, it appears that superpotent topical corticosteroids should remain the first-line treatment for OELP.

Clinical and haemodynamic risk factors associated with discrepancies in lower limb length with capillary malformations: data from the national paediatric French cohort CONAPE.

BACKGROUND: Genetics discoveries have allowed for a better understanding of capillary malformations (CMs) associated with overgrowth syndrome. However, molecular analyses are still not easy to perform or interpret. Other analytical methods are needed. OBJECTIVES: To identify clinical and haemodynamic factors associated with leg length discrepancy (LLD) in children with CMs of the lower limbs. METHODS: Data were obtained from the multicentre French national cohort CONAPE (COhorte Nationale d'enfants atteints d'Angiome Plan de membrE inférieur), from children aged 2-12 years old with CMs of the lower limbs. Clinical characteristics were prospectively collected. Haemodynamic factors were measured by an sonographer who calculated the arterial blood flow (ABF) in both lower limbs. An ABF difference ≥ 50% between the two lower limbs was considered relevant. LLD ≥ 2% was determined by the same radiologist on centralized radiographs. RESULTS: We analysed data at baseline for 96 children. The mean ± SD age was 5·6 ± 3·1 years; 49 (51%) were male; and 14 (15%) showed LLD. In total, 32 patients (33%) had venous anomalies, 13 (14%) lymphatic anomalies and in one child a diagnosis of Parkes Weber syndrome was made. Only an increased circumference above the knee was more frequent with than without LLD (43% vs. 13%, P = 0·02). In all, 10/79 patients (13%) showed a difference in ABF ≥ 50%: four had LLD. The frequency of differences in ABF ≥ 50% was greater with than without LLD [33% (n = 4/12) vs. 9% (n = 6/67), P = 0·04]. CONCLUSIONS: ABF measured by Duplex ultrasonography is a simple, low-cost and noninvasive complementary examination for help in detecting LLD, with a difference of ≥ 50% possibly associated.

[Aphthous mouth ulcers as an initial manifestation of sécukinumab-induced inflammatory bowel disease]. / Ulcérations buccales aphtoïdes inaugurales d'une maladie inflammatoire chronique de l'intestin induite par le sécukinumab.

BACKGROUND: Secukinumab, a humanized monoclonal antibody targeting interleukin 17A, has been associated with the development of inflammatory bowel diseases. We report a case of a female patient developing recurrent oral ulcers prior to inflammatory bowel disease induced by secukinumab. The patient had developed similar oral ulcers 6 years earlier while on tocilizumab (targeting IL6R), suggesting an immunological link between the two episodes. PATIENTS AND METHODS: A 36-year-old female patient had refractory spondylarthrosis. In 2010, she had presented oral aphthous ulcers during treatment with tocilizumab. In 2011, tocilizumab was stopped and the ulcers resolved. In 2016, secukinumab was introduced and led to recurrence of oral aphthous ulcers followed by ileitis-pancolitis. Corticosteroids and ustekinumab resulted in partial remission. DISCUSSION: The patient developed inflammatory bowel disease during treatment with secukinumab, preceded by recurrent oral aphthous ulcers. She had presented similar oral ulcers 6 years earlier while on a treatment targeting IL6R. IL6 is a pleiotropic cytokine that may activate the Th17 pathway. Thus, tocilizumab could have induced an "anti-IL17-like" effect, accounting for the occurrence of oral aphthous ulcers, possibly related to mild inflammatory bowel disease. CONCLUSION: The occurrence of oral ulcers during treatment with secukinumab may herald inflammatory bowel disease. In patients with a previous history of recurrent aphthous stomatitis, especially where induced by previous biologics, consideration must be given to the risk-benefit ratio of prescribing an anti-IL17 antibody.

Topical sirolimus solution for lingual microcystic lymphatic malformations in children and adults (TOPGUN): study protocol for a multicenter, randomized, assessor-blinded, controlled, stepped-wedge clinical trial.

BACKGROUND: Lingual microcystic lymphatic malformations (LMLMs) are rare congenital vascular malformations presenting as clusters of cysts filled with lymph fluid or blood. Even small well-limited lesions can be responsible for a heavy burden, inducing pain, aesthetic prejudice, or oozing, bleeding, infections. The natural history of LMLMs is progressive worsening punctuated by acute flares. Therapeutic options include surgery, laser excision, and radiofrequency ablation but all are potentially detrimental and expose to local relapse. Therefore, the management frequently relies on a "watchful waiting" approach. In complicated LMLMs, treatment with oral sirolimus, a mammalian target of rapamycin (mTOR) inhibitor, is often used. Topical applications of sirolimus on the buccal mucosae have been reported in other oral diseases with good tolerance and none to slight detectable blood sirolimus concentrations. We aim to evaluate the efficacy and safety of a 1 mg/mL sirolimus solution applied once daily on LMLM of any stage in children and adults after 4, 8, 12, 16, 20, and 24 weeks of treatment compared to usual care (no treatment). METHODS: This is a randomized, multicentric study using an individually randomized stepped-wedge design over 24 weeks to evaluate topical application of a 1 mg/mL sirolimus solution once daily, on LMLM, versus usual care (no treatment), the control condition. Participants begin with an observational period and later switch to the intervention at a randomized time (week 0, 4, 8, or 12). Visits occur every 4 weeks, either in the study center or by teleconsulting. The primary outcome will be the evaluation of global severity of the LMLM on monthly standardized photographs by 3 independent blinded experts using the physical global assessment (PGA) 0 to 5 scale. Secondary outcomes will include lesion size measurement and quality of life assessment, investigator, and patient-assessed global disease and specific symptoms (oozing, bleeding, sialorrhea, eating impairment, taste modification, aesthetic impairment, pain, and global discomfort) assessment. A biological monitoring will be performed including residual blood sirolimus concentration and usual laboratory parameters. DISCUSSION: Given the disappointing state of current treatment options in LMLMs, topical sirolimus could become firstline therapy in treating LMLMs if its efficacy and safety were to be demonstrated.
