چکیده

A fibromialgia corresponde a uma condição dolorosa musculoesquelética crônica que se diagnostica por meio da presença de dor crônica e difusa, e pela presença de dor à compressão de pelo menos onze de dezoito pontos anatomicamente determinados. Nos distúrbios do sono, embora não constituam critério diagnóstico, são freqüentes, em especial, os eventos de fragmentação do sono, tais como o aumento do número de despertares breves, aumento de oscilações cíclicas alternantes do padrão do sono e intrusão de ondas alfa no sono não-REM. A presença de sono não restaurador constitui um importante aspecto dentre as manifestações da fibromialgia, o que torna necessária a investigação de desordens primárias do sono na avaliação dos pacientes acometidos. A associação entre fibromialgia e transtornos respiratórios do sono foi inicialmente descrita em 1986, ao se constatar que três dentre onze pacientes com apnéia do sono preenchiam critérios para fibromialgia. Em sete dos pacientes a polissonografia revelou padrão de fragmentação do sono, semelhante ao padrão alfa-delta.(1) A partir desse estudo pode-se dividir as publicações entre as que estudam transtornos respiratórios do sono em pacientes com fibromialgia e as que estudam manifestações de fibromialgia em pacientes com apnéia do sono. A presença de transtornos respiratórios do sono em pacientes com fibromialgia tem sido mais estudada. Dentre as publicações, destacase um estudo de 1993, em vinte pacientes com fibromialgia e dez voluntários hígidos. Os autores não observaram diferença em freqüência de elevação do índice de apnéia e hipopnéia maior que cinco eventos por hora de sono entre os grupos (20% dos casos em ambos), porém constataram que os pacientes com apnéia do sono apresentavam maior fragmentação do sono.(2) De Transtornos respiratórios do sono e fibromialgia Respiratory sleep disorders and fibromyalgia
