Single serologic tests may occasionally influence clinicians in making diagnoses. The antistreptolysin O (ASO) test is a frequently used tool for detecting recent Streptococcus pyogenes infection and is helpful in the diagnosis of diseases like rheumatic fever. Using data from a 1989 prospective study of 600 healthy male military recruits, in which 43% experienced S. pyogenes upper respiratory ...

Antistreptolysin O (ASO) titers were determined on 117 human sera with rabbit, human, and sheep red blood cells (RBC) as the indicator system in the ASO tube test. The titers of 65% of the sera were one dilution step higher when a 5% suspension of sheep RBC was used instead of a 5% suspension of rabbit RBC. Titers were one dilution step higher in 42.7% of the sera when a 5% suspension of human ...

Since 1935 several reports have dealt with the antistreptolysin-O (ASO) titre in rheumatoid arthritis (RA). The mean and the upper ASO values were first established in a group of normal subjects and in patients with no history of recent streptococcal illness, and subsequently the distribution of the ASO titres was recorded in patients suffering from RA. Table I summarizes the results of Blair a...

The streptozyme test was compared with the antistreptolysin O (ASO), antideoxyribonuclease B (ADN-B), and antihyaluronidase (AH) tests. One hundred and twenty-seven human serum specimens were tested by each of the four tests. The streptozyme test detected more specimens with elevated titers than any single test; however, it was not as effective as the combination of the ASO and ADN-B tests. The...

"Upper limits of normal" antistreptolysin O (ASO) and antideoxyribonuclease (ADN) B titers were determined on serum specimens from various age groups of pediatric patients with no history of a recent streptococcal infection and on healthy adult hospital employees. The upper limit of normal value is that level of antibody titer exceeded by no more than 15% of the total subjects in each age group...

OBJECTIVE Behcet's disease is a multisystem inflammatory disorder, and its etiology has not been defined clearly yet. In this study, we aimed to investigate the antistreptolysin O (ASO) levels of patients with Behcet's disease. MATERIALS AND METHODS Thirty patients with Behcet's disease and 30 healthy controls were enrolled in this study. We measured erythrocyte sedimentation rate (ESR), seru...

This study is designed to evaluate the immune status of schoolchildren with respect to Streptococcus pyogenes, and to ascertain the usefulness of antideoxyribonuclease B (ADNase B). Antistreptolysin O (ASO) and ADNase B concentrations were measured quantitatively in 266 serum samples from healthy elementary school children in Seoul. Simultaneously, throat cultures were taken in order to isolate...

A 19-year male presented with acute onset, gradually progressive symmetric indurations involving the skin over the face, neck, shoulders and upper part of chest following an upper respiratory tract infection. Detailed history and examination did not reveal evidence of Raynauds' phenomenon, nail changes, digital ulcers, pigmentation or any systemic involvement. Autoantibodies for systemic sclero...

Chorea is a rare manifestation of systemic lupus erythematosus (SLE). We report on a young patient with chorea who was diagnosed initially with rheumatic fever. Follow up and further evaluation confirmed the diagnosis of SLE and anti-phospholipid syndrome. Of special interest were the negative antiphospholipid (aPL) antibodies and the initial diagnosis of rheumatic fever which is still not unco...
