An 8-year-old girl died suddenly without prior symptoms. Post-mortem examination identified both systemic group A streptococcal infection and hypertrophic cardiomyopathy. She had no history of cardiac symptoms and was not in a high-risk group for sudden death due to hypertrophic cardiomyopathy. We believe the disseminated but asymptomatic group A streptococcal infection precipitated her early d...
Serum levels of 3 group A streptococcal antibodies were determined in 53 patients prior to mitral commissurotomy and monthly for 3 to 6 months postoperatively. Significant elevation of antibody titers was relatively infrequent prior to commissurotomy and the presence of chronic productive inflammatory lesions in the biopsied atrial appendage was usually unrelated to recent streptococcal infecti...
BACKGROUND The incidence and severity of invasive group A streptococcal infection demonstrate great variability over time, which at least, in part, seems to be related to group A streptococcal type distribution among the human population. METHODS An enhanced surveillance study of invasive group A streptococcal infection (746 isolates) was performed in Sweden from April 2002 through December 2...
Bacterial and viral triggers are suspected agents in the initial etiology of autoimmune diseases. There are some studies on the etiology of autoimmune disorders which have focused on streptococcal infection and a possible relation with microbial heat shock proteins (hsp) which show significant homology with human heat shock proteins. In addition, some serotypes of streptococci cross-react ...
Background and objectives: Rheumatic fever is a main problem of developing countries, whereas in developed countries its prevalence is low. Proper diagnosis and adequate treatment of beta streptococcal infection can effectively prevent such unwanted sequel. Materials and Methods: Following completion of a questionnaire regarding age, sex, location etc. blood sample was collected and ASO titer w...
Background and Objective: Streptococcal pharyngitis is one of the most common bacterial infections that its improper treatment could lead to complications such as heart and kidney problems. Although streptococcal pharyngitis makes up a low percentage of pharyngitis etiology, penicillin derivatives are prescribed for many of the patients with pharyngitis. The aim of this study was to determine t...
Background: Infection with group B streptococcus (GBS) can present with respiratory distress, Pneumonia, meningitis and Osteomyelitis in neonates. The aim of this study was to determine the prevalence of GBS colonization in trachea of intubated neonates.Methods: This observational analytic study was performed upon 33 intubated neonates due to respiratory distress in neonatal intensive care unit...
BACKGROUND The role of non-group A streptococci (non-GAS) as pathogens of acute pharyngitis is controversial. Data are limited and conflicting on whether these bacteria are true pathogens of pharyngitis and whether treatment is indicated in all cases or just select cases. However, non-GAS are well-documented as being pathogens of other diseases, including neonatal sepsis, pneumonia, endocarditi...
From 2009 to 2014, we prospectively enrolled 132 children with perianal infections. The presentation of painful defecation, anal fissures, and macroscopic blood in stools was highly suggestive of group A streptococcal perianal infection (probability 83.3%). We found a high sensitivity of a group A streptococcal rapid diagnostic testing (98%) but relatively low specificity (72.8%).
