Article Synopsis
- CRUSE® is an app designed for people with chronic spontaneous urticaria (CSU) to track their symptoms using visual analogue scales (VASs), aiming to assess the app's effectiveness in measuring disease activity.
- A study analyzed three VASs related to CSU impact on daily life, including one specifically for the severity of urticaria, one for productivity, and a general health measure (EQ-5D), using data from nearly 6,000 patients over many days.
- The results showed that the CRUSE® app's VASs demonstrate strong validity and reliability, with the "VAS urticaria" being most effective in capturing symptom changes, while the minimal important difference (MID) values indicated meaningful changes
Background: Chronic spontaneous urticaria (CSU) is unpredictable and can severely impair patients' quality of life. Patients with CSU need a convenient, user-friendly platform to complete patient-reported outcome measures (PROMs) on their mobile devices. CRUSE , the Chronic Urticaria Self Evaluation app, aims to address this unmet need.

Patients And Methods: Materials and methods: The study basis is represented with the results of examination and treatment of 252 patients with psoriatic arthritis. The biopsy samples from the problem psoriatic eruption and intact skins regions, received from 74 patients, were studied.
Two new triterpenoid saponins 1 and 2 were isolated from the methanol extract of the roots of Acanthophyllum gypsophiloides Regel. These saponins have quillaic acid or gypsogenin moieties as an aglycon, and both bear similar sets of two oligosaccharide chains, which are 3-O-linked to the triterpenoid part trisaccharide α-L-Arap-(1→3)-[α-D-Galp-(1→2)]-β-D-GlcpA and pentasaccharide β-D-Xylp-(1→3)-β-D-Xylp-(1→3)-α-L-Rhap-(1→2)-[β-D-Quip-(1→4)]-β-D-Fucp connected through an ester linkage to C-28. The structures of the obtained saponins were elucidated by a combination of mass spectrometry and 2D NMR spectroscopy.
