2010 ACR adult FM criteria useful in screening for juvenile fibromyalgia

The American College of Rheumatology 2010 adult fibromyalgia criteria can be successfully applied by pediatricians when screening pediatric and adolescent patients for fibromyalgia, but confirmation from a rheumatologist is still recommended, according to researchers from the Cincinnati Children’s Hospital.
The researchers studied 44 patients (mean age: 15.02 years) previously diagnosed with juvenile fibromyalgia (FM) by a rheumatologist. Diagnosing physicians reported whether American College of Rheumatology (ACR) 1990 or Yunus and Masi criteria were used in making the diagnosis. The patients were matched by age and gender to 44 controls who experienced localized pain conditions such as headaches, abdominal aches or limb pain.
The ACR 2010 Widespread Pain Index for identifying pain in specific body locations and the Symptom Severity checklist for assessing somatic symptoms were administered to patients and control participants by a trained assessor. The ACR FM 2010 algorithm was applied to the scores to determine diagnosis of FM, and T-tests were used to compare the two groups on the number of pain locations and number of reported symptoms.
In prior diagnoses, the researchers found that Yunus and Masi criteria were most often used (93.2%) to classify FM vs. ACR 1990 (6.8%). Application of ACR 2010 criteria diagnosed active FM in 83.7% of the juvenile patients, along with 11.4% of the control participants with localized pain. However, the patients in the FM group reported significantly more pain locations and symptoms than the control group, according to the researchers.
The researchers concluded that the ACR 2010 adult FM criteria can be applied successfully by pediatricians, but that clinical confirmation by a specialist is recommended, and that further studies of larger groups should be undertaken. – by Shirley Pulawski
