Upper limit of normal antistreptolysin-O titer in healthy school children.

چکیده
We studied the level of ASO (anti streptolysin O) titer and throat culture for GABHS (group A beta hemolytic streptococci) in 200 normal healthy school children between 5 to 15 years of age. We noted the upper limit of normal titer of 242 IU in the healthy school children around Mysore city. Throat culture was positive for GABHS in 9% of healthy school children indicating the carrier state.

"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...

Over diagnosis of acute rheumatic fever (ARF) based on a raised antistreptolysin O titer (ASOT) is not uncommon in endemic areas. In this study, 660 children (aged 9.2 ±1.7 years) were recruited consecutively and classified as: G1 (control group, n=200 healthy children), G2 (n=20 with ARF 1(st) attack), G3 (n=40 with recurrent ARF), G4 (n=100 with rheumatic heart disease (RHD) on long acting pe...

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 ...
متن کاملAntistreptolysin levels in normal infants and young children.
A modified method of estimating the antistreptolysin O titre (A.S.O.) is described. The A.S.O. of 279 sera from normal children under 5 years of age is recorded, together with that of 40 children over 5 years of age. The results show a range much lower than that found in adults and older children and are discussed with respect to estimations made in children with proven infections. The signific...
