Fibromyalgia with psoriatic arthritis affects the treatment, according to a study

A recent study in the Journal of Rheumatology showed that patients with fibromyalgia (FM) and psoriatic arthritis (PA) may experience worse arthritic symptoms, and suggests that physicians should consider different ways of determining treatment plans for patients with both diseases than treatments unnecessary can be avoided. 
The study, the effect of the presence of fibromyalgia on the clinical activity of common diseases in patients with psoriatic arthritis: a cross-sectional study, led by S. Birkman of the departments of rheumatology and dermatology Tel Aviv Sourasky Medical Center, included 73 people with the PSA.
The researchers measured whether the study participants also had FM according to the criteria of the American College of Rheumatis. The team gave all the participants a clinical evaluation of the activity of the disease. The scientists quantified the activity of the disease using psoriatic disease compound activity index (CPDAI), with low disease activity (MDA) and disease activity index in psoriatic arthritis (DAPSA). 
The participants also completed several established questionnaires, including the Health Assessment Questionnaire (HAQ), the activity index of the Ankylosing Spondylitis Bath disease (BASDAI), the Dermatology quality of life index and the Leeds endetesitis index (LEI).
Thirteen patients with PAs also had FM. The scores of DAPSA were significantly higher in patients with AP and FM compared to patients with PAs only. The scores of HAQ, BASDAI and LEI were also more severe in patients with AP and FM. 
The researchers concluded: “The coexisting FM is related to worse scores in all measures analyzed with PsA. Its influence must be taken into account in the treatment algorithm to avoid an unnecessary update of the treatment “. 
Fibromyalgia is a painful disorder that sometimes health care providers do not recognize as a real medical condition. Characterized by extreme fatigue and chronic pain, often in localized regions of the body, FM can occur along with other painful conditions, such as arthritis. PsA is a type of arthritis that affects some people with psoriasis, a skin condition characterized by red, pruritic scales and by the accumulation of skin cells.
