OBJECTIVE. To assess the outcome of fibromyalgia syndrome (FM) in a
30-month followup study of children with FM.
METHODS. In the
original study to assess the prevalence of FM in healthy
schoolchildren, we found 21 children with FM and an additional
7 fulfilling the point count criterion only (11 of 18).
Fifteen of the 21 and all 7 were recruited for a 2nd
assessment in our present study. In all children, a count of
18 tender points (TP) was conducted by thumb palpation.
Tenderness of 9 of the TP sites as well as 4 control point
sites was further assessed using a Chatillon dolorimeter. All
children were questioned concerning the presence of widespread
pain or aching. Children were considered to have FM if they
met the American College of Rheumatology criteria for
RESULTS. After 30 months, 11 of the 15 children
with FM (73%) were no longer fibromyalgic. The mean point
count of the 15 children significantly decreased from 12.5 to
4.6 (p < 0.001). The mean tenderness threshold of the 9 tender
sites increased from 2.4 to 3.4 kg (p < 0.01), and the mean
tenderness threshold of the 4 control sites increased from 4.1
to 5.6 kg (p < 0.05). Of the 7 children initially fulfilling
the point count criterion only, none had developed FM. Their
mean point count decreased from 11.4 to 3.4 (p = 0.001), and
their mean tenderness thresholds increased from 2.7 kg to 3.9
kg (p = 0.001) at tender sites and from 4.3 kg to 6.8 kg (p <
0.001) at control sites.
CONCLUSION. We suggest that the
outcome of FM in children is more favorable than in adults.
More followup studies are needed to clarify the longterm
outcomes of FM in children and adults.
