OBJECTIVE Anti-streptolysin O (ASO) and anti-DNase B (ADB) titers are used for the diagnosis of poststreptococcal complications. Ranges of normal values of ASO and ADB titers vary, depending on age, population and different time intervals. Although many studies have been performed for determination of the ASO titer in our country, only a few studies have been conducted for specification the upp...

OBJECTIVES To report the pharyngeal colonization rate of β-hemolytic streptococci and changes in the value of antistreptolysin O (ASO) and anti-DNase B serology titers during pregnancy. METHODS Healthy pregnant women were recruited and blood was drawn in each trimester. The upper limit of normal (ULN) values for ASO and anti-DNase B was calculated for each trimester. Throat swabs were collect...

"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...

OBJECTIVES The main aim of this study is to evaluate the significance of several clinical and laboratory findings presented by a large number of pediatric patients who were suspected to have acute rheumatic fever (ARF) by physicians who ordered echocardiogram for confirmation and for avoiding overuse of unnecessary antibiotics. These suspecting reasons include elevated ASO titers and recurrent ...

Because previous studies revealed that high levels of antibody to the group A streptococcal carbohydrate (A-antibody) persist in the serum of patients with chronic rheumatic valvular disease, the effect of valvular surgery on the level of this antibody was examined in the present study. Streptococcal antibody titers (ASO, anti-DNAse B, and A-antibody) were determined on 73 patients admitted for...

BACKGROUND & OBJECTIVES For the serodiagnosis of group A streptococcal (GAS) infections and their late sequelae, a battery of tests have been suggested. However, anti-streptolysin O (ASO) and antideoxyribonuclease B (ADNase B) are the most widely accepted tests for the same. It is essential to evaluate the upper limits of ASO and ADNase B levels in age and sex matched normal population before u...

Fifty cases of AGN, aged between 3-13 years admitted to the Pediatric wards of J.J.M. Medical College formed the material of this study. The criteria for selection of cases were: acute onset of edema, oliguria and hematuria with or without hypertension and proteinuria along with evidence of antecedent streptococcal infection (history of recent pyoderma, healed ulcers or raised ASO titer). A det...

We conducted this study to identify the clinical features and risk factors for atypical acute post-streptococcal glomerulonephritis (APSGN). Thirty-five cases of atypical APSGN treated at Srinagarind Hospital during 2002-2009 were compared with 27 typical cases. The clinical symptoms, anti-streptococcal antibody titers, and laboratory data at the first hospital visit were compared between the t...

A quantitative microagglutination test for measuring group A streptococcal antibody levels is described and evaluated. The pro­ cedure requires only a patient’s serum and a standardized antigen consisting of pepsin and trypsin treated group A streptococcal cells. The antibody measured appears to be directed mainly at the group A carbohydrate of the cell wall. In “normal” populations, basal tite...
