JUVENILE FIBROMYALGIA - CLINICAL AND POLYSOMNOGRAPHIC ASPECTS

Objective, To identify the child-mother diagnostic correlation in fibr omyalgia (FM), to study sleep disturbance in juvenile FM, and to compa re clinical aspects and sleep disorders between these groups. Methods, We studied 34 children with confirmed FM aged 11 +/- 1 years, 10 chil dren with diffuse pain, and 17 age and sex matched asymptomatic contro ls. The respective 61 mothers were included: 34 asymptomatic and 27 wi th FM. All participants were subjected to clinical evaluation, a sleep questionnaire, and nocturnal polysomnography, preceded by a night of adaptation. Sleep scoring was done visually and a computerized analysi s was performed for alpha, theta, and delta waves in slow wave sleep ( SWS). Results. A significant predominance of mothers with FM was obser ved in the group of children with FM (71%) compared to children with d iffuse pain (30%) and asymptomatic children (0%). According to the sle ep questionnaire, the complaints of superficial sleep and nonrestorati ve sleep were more prominent in mothers with FM than in children with FM, whereas motor agitation during sleep was more frequent in the chil dren with FM. Polysomnographic anomalies were also more prominent in m others with FM than in children with FM in terms of decrease in sleep efficiency, increase of number of arousals during sleep, and alpha int rusion in SWS. Both FM groups presented an increased alpha + theta tim e/delta time index during SWS compared to respective controls, and mot hers with FM also showed an increase in alpha time/delta time index du ring SWS, compared to asymptomatic mothers. A correlation was found be tween alpha + theta time/delta time index during SWS and intensity of clinical manifestations of pain and sleep anomalies in children and th eir mothers. Conclusion, Significant concordance was observed regardin g FM diagnosis in children and their mothers. Sleep complaints and pol ysomnography findings were less prominent in affected children compare d to mothers with FM. In addition, we observed a significant correlati on between polysomnographic indexes, sleep anomalies, and pain manifes tations in children and their mothers.
