The value of knowing: preferences for genetic testing to diagnose rare muscle diseases.

Background: Genetic testing can offer early diagnosis and subsequent treatment of rare neuromuscular diseases. Options for these tests could be improved by understanding the preferences of patients for the features of different genetic tests, especially features that increase information available to patients.

Methods: We developed an online discrete-choice experiment using key attributes of currently available tests for Pompe disease with six test attributes: number of rare muscle diseases tested for with corresponding probability of diagnosis, treatment availability, time from testing to results, inclusion of secondary findings, necessity of a muscle biopsy, and average time until final diagnosis if the first test is negative.

Measurement Properties of 2 Novel PROs, the Pompe Disease Symptom Scale and Pompe Disease Impact Scale, in the COMET Study.

Background And Objectives: The Pompe Disease Symptom Scale (PDSS) and Impact Scale (PDIS) were created to measure the severity of symptoms and functional limitations experienced by patients with late-onset Pompe disease (LOPD). The objectives of this analysis were to establish a scoring algorithm and to examine the reliability, validity, and responsiveness of the measures using data from the COMET clinical trial.

Methods: The COMET trial was a randomized, double-blind study comparing the efficacy and safety of avalglucosidase alfa and alglucosidase alfa in patients with LOPD aged 16-78 years at baseline.

Qualitative interviews to improve patient-reported outcome measures in late-onset Pompe disease: the patient perspective.

Background: Late-onset Pompe Disease (LOPD) is a rare, heterogeneous disease manifested by a range of symptoms varying in severity. Research establishing the frequency of these symptoms and their impact on patients' daily lives is limited. The objective of this study was to develop a conceptual model that captures the most relevant symptoms and functional limitations experienced by patients with LOPD, to inform the development of new patient-reported outcome (PRO) tools.

Assessing United States Patient and Dermatologist Experiences with Severe Chronic Hand Eczema.

Objective: Patients with severe chronic hand eczema often have persistent symptoms that interfere with daily activities, social functioning, and employment. Many patients are refractory to topical corticosteroids. This survey-based study was performed to characterize treatment experiences, impact on productivity, and quality of life of patients with severe chronic hand eczema; understand dermatologists' severe chronic hand eczema treatment patterns.
