Bacteriological and serological study on synovial Fluid in septic arthritis patients

Identification of bacterial antigens and super antigens in synovial fluid of patients with arthritis: a cross sectional study

  Background : An accurate and prompt diagnosis of bacterial arthritis is essential for earlier treatment and a good outcome. Superantigens produced by Staph. Aureus are among the most lethal toxins. The paper objective was Identification of common bacterial antigens and S.aureus superantigens in synovial fluid (SF) of children with negative culture and direct smear for other bacteria except fo...

Synovial fluid adenosine deaminase activity to diagnose tuberculous septic arthritis.

There are reports of a correlation between high adenosine deaminase (ADA) levels in body fluid and tuberculosis (TB) infection, but none have evaluated synovial fluid ADA and TB arthritis. The objectives of this study were to determine the proper cut-off level for synovial fluid adenosine deaminase (SF-ADA) and the sensitivity and specificity of SF-ADA to diagnose TB arthritis. Between January ...

Synovial Fluid in Patients with Lyme Arthritis

Comparative Measurement of Rheumatoid Factor in Serum and Synovial Fluid of Rheumatoid Arthritis Patients by ELISA and Latex-Agglutination Test

Rheumatoid factors (RF) are autoantibodies with specificity for the Fc portion of human IgG. Production of RF is a characteristic feature of rheumatoid arthritis (RA) and is detectable in high titer in about 90% of these patients. In this study, we measured total IgM, IgA, IgMRF and IgARF in serum and synovial fluid of 45 RA patients by ELISA and the results were compared with those obtained b...

Synovial lactic acid and septic arthritis.

To the Editor: In their Rational Clinical Examination article, Dr Margaretten and colleagues concluded that the synovial fluid white blood cell count and the corresponding percentage of polymorphonuclear cells are the most useful markers in identifying septic arthritis while waiting for the Gram stain and culture test results. Synovial fluid glucose, protein, and lactate dehydrogenase were not ...
