Abstract

Introduction: Since during the COVID-19 pandemic nail psoriasis was evaluated exclusively with teledermatology, dermatologists started to face the difficulty in rating it concurrent with other onycopathies (i.e., onychotillomania and onychophagy). Thus, we aimed to improve the existing severity scores and verify the value in different clinical settings (i.e., in person vs. teledermatology (video or picture)). Methods: This multicenter prospective observational study evaluated patients with nail psoriasis and screened them for onychophagy or onychotillomania in telemedicine from May 2020 to January 2021. For therapeutic purposes patients with nail psoriasis were followed and rated with the Nijmegen-Nail psoriasis Activity Index tooL (N-NAIL) for 9 months; at the same time, N-NAIL and a new dedicated index that monitor also the changes in nail dimension (Galeazzi-(G) N-NAIL) were tested for accuracy. We assessed inter- and intraobserver agreement for the three different settings (in person, video, and pictures). Results: In our cohort of 382 patients with nail psoriasis after a clinical and dermatoscopic assessment we found 20 (5.24%) patients with onychophagy and 17 (4.45%) patients with onychotillomania. Analysis of the impact of nail psoriasis on patients revealed that onycholysis and crumbing, followed by subungual hyperkeratosis, were the clinical signs that prevalently bothered patients. N-NAIL score displayed moderate intra- and interobserver agreement. Over the 9 months follow-up, N-NAIL vs. GN-NAIL displayed a solid correlation at all the examined time points, i.e., baseline and after 3, 6, and 9 months. Conclusion: We created a new tool, the GN-NAIL capable of efficiently scoring nail psoriasis severity in complex cases, such as patients with onychotillomania and onychophagy, and monitor response to treatment during the COVID-19 pandemic.
