Real-World Multinational Survey of Chronic Inflammatory Demyelinating Polyneuropathy: Disease Characteristics and Therapeutic Landscape
Background and Aims
Chronic inflammatory demyelinating polyneuropathy (CIDP) is an immune-mediated syndrome characterized by progressive muscle weakness and sensory impairment. Clinical similarities with other neuropathies can cause misdiagnoses and delayed diagnoses. Additionally, a large proportion of patients appropriately treated according to current guidelines still show residual disability. This real-world study aimed to characterize a global cohort of patients with CIDP.
Methods
Data were drawn from the Adelphi CIDP Disease Specific Programme, a cross-sectional survey with retrospective data collection, conducted in China, France, Germany, Italy, Japan, Spain, the United Kingdom, and the United States between September 2022 and April 2023. Neurologists and neuromuscular specialists reported on patient demographic and clinical characteristics at the time of the survey. Patients self-reported treatment satisfaction, disease control, and health-related outcome measures.
Results
Overall, 164 physicians provided data for 1056 patients, with 428 (40.5%) providing self-reported data. Patients were diagnosed with typical CIDP (69.2%) and variant CIDP (30.8%). Overall, initial misdiagnosis occurred in 37.2% of patients, with a median (interquartile range) diagnostic delay of 6.0 (3.0–12.0) months. Maintenance therapy was prescribed for 81.6% of patients, with corticosteroid use ranging from 25.7% in the United States to 80.0% in China. Some patients were dissatisfied by treatment outcomes (11.0%) and symptom control (12.2%). Overall, mean (SD) patient-reported scores were 62.1 (20.4) for I-RODS, 35.0 (11.1) for FACIT fatigue, and 0.662 (0.253) for EQ-5D-5L.
Interpretation
Diagnostic delay and misdiagnoses were common occurrences across typical CIDP and variant CIDP. Despite the use of guideline treatments, there were unmet needs and a continued disease burden for patients.
期刊介绍：
The Journal of the Peripheral Nervous System is the official journal of the Peripheral Nerve Society. Founded in 1996, it is the scientific journal of choice for clinicians, clinical scientists and basic neuroscientists interested in all aspects of biology and clinical research of peripheral nervous system disorders.
The Journal of the Peripheral Nervous System is a peer-reviewed journal that publishes high quality articles on cell and molecular biology, genomics, neuropathic pain, clinical research, trials, and unique case reports on inherited and acquired peripheral neuropathies.
Original articles are organized according to the topic in one of four specific areas: Mechanisms of Disease, Genetics, Clinical Research, and Clinical Trials.
The journal also publishes regular review papers on hot topics and Special Issues on basic, clinical, or assembled research in the field of peripheral nervous system disorders. Authors interested in contributing a review-type article or a Special Issue should contact the Editorial Office to discuss the scope of the proposed article with the Editor-in-Chief.
