Psossibility and appropriate timing of discontinuation of dupilumab for atopic dermatitis (AD) remain unclear. We explored the possibility of patients, who could maintain remission with topical therapy alone after withdrawing dupilumab in the real world. Furthermore, we identified their characteristics. All adult AD patients who initiated dupilumab from June 2018 to July 2022 and were treated with dupilumab for more than 3 months at our hospital were included in this study. The observation period was from June 2018 to July 2023. In 138 patients, 58 (42.0%) discontinued dupilumab at least once. Among them, 18 (13.0%) discontinued dupilumab but reinitiated dupilumab later due to exacerbation. Only seven patients (5.1%) could maintain remission with topical therapy alone after discontinuation of dupilumab, with characteristics of lower POEM, VAS of pruritus, serum levels of TARC and LDH, and neutrophil counts at baseline, and those of longer duration of dupilumab until its discontinuation (24.0 ± 13.3 vs. 12.8 ± 7.3 months) and lower EASI and affected BSA at the discontinuation of dupilumab. In 118 patients treated with dupilumab for at least 1 year, 38 patients (32.2%) discontinued at least once. Only four patients (3.4%) could maintain remission with topical therapy alone after discontinuation of dupilumab, with characteristics of lower POEM at baseline and lower EASI at the discontinuation of dupilumab. In conclusion, maintaining remission after withdrawing dupilumab is challenging. Discontinuation of dupilumab may be considered in patients with low baseline POEM, after more than 2 years of dupilumab treatment, with a substantial decrease in EASI., (© 2024 John Wiley & Sons A/S.

Recent studies indicate that hepatic diseases are associated with psoriasis. Non-invasive tests, including the Fibrosis-4 (FIB-4) index, which can confidently rule out the presence of advanced fibrosis, are currently receiving attention. However, data on the FIB-4 index in psoriasis patients and the effects of biologics on the FIB-4 index are limited. We investigated the relationships between the FIB-4 index and demographic or clinical characteristics as well as the effects of biologics on the FIB-4 index in psoriasis patients. Psoriasis patients aged 36-64 years, whose treatment was initiated with interleukin (IL)-17 inhibitors or IL-23 inhibitors for psoriasis from May 2015 to December 2022, were consecutively included. Data were collected retrospectively from the patients' charts. A total of 171 psoriasis patients were included in this study. Thirty-four, 43, 21, 32, and 41 psoriasis patients were treated with secukinumab, ixekizumab, brodalumab, guselkumab, or risankizumab, respectively. In biologics-naïve patients, a significant but weak positive correlation was observed between the FIB-4 index and age (r = 0.3246, p = 0.0018). There was no significant correlation between the FIB-4 index and other demographic or clinical characteristics. Regarding the effects of biologics on the FIB-4 index, no significant change was observed in psoriasis patients treated with any biologics. However, in psoriasis patients with a baseline FIB-4 index of >1.3, patients treated with guselkumab and those treated with either IL-23 inhibitor showed significantly decreased FIB-4 index scores 6 months after initiating the biologics (p = 0.0323, p = 0.0212). In contrast, no change was observed in FIB-4 index scores in patients treated with IL-17 inhibitors. In conclusion, our study revealed that the FIB-4 index was correlated with age in psoriasis patients. Furthermore, IL-23 inhibitors (but not IL-17 inhibitors) decreased the FIB-4 index score at 6 months in psoriasis patients with elevated FIB-4 index scores at baseline. Further studies are needed to clarify whether IL-23 inhibitors improve liver fibrosis physiologically and functionally., (© 2024 Japanese Dermatological Association.)

Recently, an autosomal recessive subtype of connective tissue disorder within the spectrum of Ehlers-Danlos syndrome (EDS), named classical-like EDS type 2 (clEDS2), was identified. clEDS2 is associated with biallelic variants in the adipocyte enhancer binding protein 1 ( AEBP1 ) gene, specifically, affecting its aortic carboxypeptidase-like protein (ACLP) isoform. We described the 15th patient (13th family) diagnosed with clEDS2. This patient presented with notable similarities in phenotype to the documented cases, along with additional characteristics such as significant prematurity and short stature. An EDS sequencing panel-based analysis revealed homozygous AEBP1: NM_001129.5:c.2923del, p.Ala975Profs*22 likely pathogenic variants, and maternally inherited heterozygous COL11A1: NM_001854.4:c.1160A>G, p.Lys387Arg variant of uncertain significance in our patient. Upon comprehensive review of all previously reported clEDS2 patients, our patient exhibited the following overlapping phenotypes, including cutaneous features: hyperextensibility, atrophic scars/delayed wound healing (100%), easy bruising (100%), excessive skin (93%); skeletal features: generalized joint hypermobility (93%), pes planus (93%), dislocation/subluxation (93%); and cardiovascular features (86%). Our patient did not display symptoms of the critical complications reported in a few individuals, including superior mesenteric artery aneurysms and ruptures, aortic root aneurysm/dissection, spontaneous pneumothoraxes, and bowel ruptures. Together, this case expands the genetic and clinical phenotypic spectrum of AEBP1-related clEDS2.

Atopic dermatitis (AD) places a burden on work productivity. Recently, dupilumab was approved for AD, but its impact on work productivity in Japanese patients has not been reported. Furthermore, data on the effect of long-term treatment with dupilumab on work productivity are limited. We investigated the work productivity and activity in Japanese patients with moderate-to-severe AD, utilizing the Japanese version of the Work Productivity and Activity Impairment (WPAI-AD-Japan) questionnaire. Furthermore, we examined the impact of dupilumab on work productivity. Adult moderate-to-severe AD patients treated with dupilumab for more than 12 months from March 2020 to June 2022 who filled out the WPAI-AD-Japan questionnaire were included. Twenty-eight adult AD patients were analysed. Absenteeism was low (mean: 5.3%), but presenteeism, work productivity loss and activity impairment were high (36.8%, 39.7%, 48.9%, respectively). Significant positive correlations were observed between work productivity loss and visual analogue scale (VAS) score of pruritus and between activity impairment and dermatology life quality index (DLQI). Dupilumab treatment significantly reduced presenteeism, work productivity loss and activity impairment at both 6 and 12 months. The extent of their amelioration was numerically higher at 12 months than at 6 months. The reduction rates in presenteeism, work productivity loss and activity impairment were positively correlated with the reduction rates in DLQI and VAS score of pruritus at 12 months. Dupilumab improved work productivity in Japanese AD patients. Long-term remission of pruritus and improved quality of life are important for comprehensive improvement of work productivity., (© 2024 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)
