Association Between Pruritus and Fibromyalgia: Results of a Population-Based, Cross-Sectional Study
Fibromyalgia is a common musculoskeletal condition that affects up to 3% of the worldwide population. Its pathogenesis is not entirely clear but is thought to involve neurogenic inflammation as well as aberrations in peripheral nerves and central pain mechanisms. It is believed that the same mechanism that causes hypersensitivity and pain in patients with fibromyalgia also predisposes them to pruritus. This population-based, retrospective, cross-sectional study was performed using a computerized database encompassing more than 4.5 million patients to examine the association between fibromyalgia and pruritus as well as pruritus-related skin conditions.
Practice Points
- Dermatologists should be aware of the connection between fibromyalgia, pruritus, and related conditions to improve patient care.
- The association between fibromyalgia and pruritus underscores the importance of employing multidisciplinary treatment strategies for managing these conditions.
Conclusion
Our findings indicate an association between fibromyalgia and pruritus as well as associated pruritic skin disorders. Given the convoluted and largely undiscovered mechanisms underlying fibromyalgia, managing patients with this condition may present substantial challenges.53 The data presented here support the implementation of a multidisciplinary treatment approach for patients with fibromyalgia. This approach should focus on managing fibromyalgia pain as well as addressing its concurrent skin-related conditions. It is advisable to consider treatments such as antiepileptics (eg, pregabalin, gabapentin) that specifically target neuropathic disorders in affected patients. These treatments may hold promise for alleviating fibromyalgia-related pain54 and mitigating its related cutaneous comorbidities, especially pruritus.
