Abstract

OBJECTIVES:

To assess the percentage of patients that fulfill the American College of Rheumatology (ACR) 1990 as well as the ACR 2010 classification criteria, to evaluate whether there is a correlation between tender points and the Widespread Pain Index (WPI) as well as signs and symptoms that predict a fibromyalgia (FM) subtype and to identify those which have greater impact on functioning.

MATERIALS AND METHODS:

We performed a cross-sectional comparative study of 206 patients with previous clinical diagnosis of FM. The studied variables were age, sex, years of disease, tender points, control points, WPI, Symptom Severity Score, subtype of FM, presence of other rheumatic disorders and the Fibromyalgia Impact Questionnaire (FIQ) score.

RESULTS:

The new diagnostic criteria of FM correctly classified 87,03% of patients who satisfied the ACR 1990 criteria. Both criteria were equally effective in assessing the impact of the disease. FM had a severe impact on the quality of life in 74,87% of patients. Somatoform disorder was the predominant subtype. Hyperalgesic FM had a significantly lower FIQ score than the somatoform disorder and depressive subtypes.

CONCLUSION:

The ACR 2010 criteria are a simple evaluation tool to use in the primary care setting, that incorporate both peripheral pain and somatic symptoms. New and old criteria should coexist; they enable a major comprehension and ease the management of this prevalent disease.
