This study was undertaken to determine the prevalence of LE cells in synovial fluid and their importance for the diagnosis of @entity627 . Synovial fluid was obtained from 631 @entity1 : 31 with @entity1252 ( @entity1252 ), 337 with @entity309 ( @entity309 ), 4 with @entity4932 , 9 with @entity785 ( @entity785 ), 27 with the @entity3928 ( @entity309 / @entity1252 ), 132 with @entity1691 ( @entity1691 ), 57 with @entity6104 , and 34 with @entity5144 ( @entity5144 ). The fluid was centrifuged, precipitate smears were done and were May-Gr  nwald-Giemsa stained for cytologic assessment. The supernatant was collected for antinuclear antibody (ANA) testing. Physicochemical and serologic properties of the synovial fluid were routinely determined. All synovial fluids demonstrated signs of @entity32 . The presence of LE cells was ascertained in five @entity1 with @entity1252 and nine @entity1 with the @entity3928 . In these cases, LE cells were accompanied by ANA. In addition, @entity1710 bodies were revealed in @entity1252 @entity1 . LE cells were observed in 2.6% of @entity1 with @entity309 but were not accompanied by ANA. @entity1 with @entity785 , @entity4932 , @entity1691 , @entity6104 , and @entity5144 tested negative for LE cells. It appears from these results that LE cells are rarely present in the synovial fluid of @entity1 with @entity627 . In contrast, they occur in more than 40% of @entity1 with the @entity3928 and may thus be regarded as important for the diagnosis of this condition.
