    BACKGROUND: Acute rheumatic fever remains a serious healthcare concern for the majority of the world's population despite its decline in incidence in Europe and North America. The goal of this statement was to review the historic Jones criteria used to diagnose acute rheumatic fever in the context of the current epidemiology of the disease and to update those criteria to also take into account recent evidence supporting the use of Doppler echocardiography in the diagnosis of carditis as ...

    Toxic shock-like syndrome (TSLS) is characterized by hypotension or shock, fever, multiorgan system involvement, and a concurrent group A streptococcal infection. We analyzed 34 streptococcal strains isolated from patients with clinically well-documented TSLS for their pyrogenic toxin profiles and M-protein types. Although strains of nine different M types were represented in the sample, 74% of the isolates were of either M type 1 or 3. It was determined that 53% produced streptococcal ...

    Despite uniform susceptibility of group A streptococci to penicillin, failure to eradicate group A streptococci is not uncommon in patients receiving penicillin for treatment of pharyngitis. We explored the possibility that penicillin tolerance could explain this phenomenon. We examined 48 group A streptococcal isolates from 48 patients successfully treated with penicillin (streptococci eradicated) and 92 isolates from 37 patients (one to four isolates per patient) who failed to respond ...

    BACKGROUND: Group A streptococci (Streptococcus pyogenes; GAS) invades human epithelial cell lines. Failure of penicillin to eradicate GAS from the throats of patients, especially those who are GAS "carriers," has been increasingly reported. However, there has been no comprehensive evaluation of how effectively antibiotics that are used to treat GAS enter upper respiratory tract epithelial cells and kill internalized GAS. We examined the viability of ingested, intracellular GAS after ...

    BACKGROUND & AIMS: The historical prevalence and long-term outcome of undiagnosed celiac disease (CD) are unknown. We investigated the long-term outcome of undiagnosed CD and whether the prevalence of undiagnosed CD has changed during the past 50 years.

    METHODS: This study included 9133 healthy young adults at Warren Air Force Base (sera were collected between 1948 and 1954) and 12,768 gender-matched subjects from 2 recent cohorts from Olmsted County, Minnesota, with either similar years ...

    BACKGROUND: Measurement of antibodies to the extracellular antigens produced by group A streptococci, antistreptolysin O (ASO) and anti-deoxyribonuclease B (anti-DNase B), is often necessary to confirm a clinical diagnosis of a previous group A streptococcal infection, especially in patients suspected of having a nonsuppurative sequel to this infection. Age is among several factors that may influence antibody levels in children. Thus, in contrast to adults, what is considered a normal ...

    Since the mid-1980s, there has been a resurgence of severe forms of invasive group A streptococcal (GAS) disease in many Western countries. In Hong Kong, a similar increase has also been observed in recent years. One hundred seven GAS isolates collected from 1995 to 1998 from individuals with necrotizing fasciitis, toxic shock syndrome, meningitis, or other type of bacteremic sepsis (invasive group, n = 24) as well as from individuals with minor skin and throat infections (noninvasive ...

    BACKGROUND: One goal of this prospective longitudinal study was to identify new group A beta-hemolytic streptococcal infections (GABHS) in children and adolescents with Tourette syndrome (TS) and/or obsessive-compulsive disorder (OCD) compared with healthy control subjects. We then examined the power of GABHS infections and measures of psychosocial stress to predict future tic, obsessive-compulsive (OC), and depressive symptom severity.

    METHODS: Consecutive ratings of tic, OC, and ...

    BACKGROUND: Two relatively small previous studies comparing once-daily amoxicillin with conventional therapy for group A streptococcal (GAS) pharyngitis reported similar rates of bacteriologic success for each treatment group. The purpose of this study was to further evaluate once-daily amoxicillin for GAS pharyngitis in a larger study.

    METHODS: In a single pediatric practice, from October through May for 2 consecutive years (2001-2003), we recruited children 3 to 18 years of age who had ...

    During 1994 and 1995, an increase in the number and severity of group A streptococcal (GAS) infections was noted in North Carolina. Ninety-six patients had GAS recovered from blood and other sterile body fluids, abscesses, and soft tissue. The overall case fatality rate was 11% but was much higher in patients with toxic shock syndrome (55%) and necrotizing fasciitis (58%). Recent invasive GAS isolates were compared with pre-1994 invasive isolates and temporally related pharyngeal ...

    We describe an outbreak of acute rheumatic fever that occurred in the intermountain area centered in Salt Lake City, Utah. Seventy-four children meeting the modified Jones criteria for the diagnosis of acute rheumatic fever were evaluated by the staff at Primary Children's Medical Center, Salt Lake City, from January 1985 through June 1986. This represents an eightfold increase over the average annual incidence at this hospital during the past decade. Carditis, a dominant feature of the ...

    BACKGROUND: Because of continuing reports from many countries of increasing resistance of group A streptococci to macrolide antibiotics, we determined the antibiotic susceptibility of recent group A streptococcal isolates from the United States.

    METHODS: We evaluated 301 Streptococcus pyogenes isolates (245 from patients with uncomplicated pharyngitis and 56 isolates from patients with invasive systemic infections) for susceptibility using the Etest technique. The isolates came from 24 ...

    OBJECTIVE: If pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections is a unique clinical entity, we hypothesized that children meeting diagnostic criteria would have more clinical exacerbations temporally linked to bona fide group A beta-hemolytic streptococcus infection than matched control subjects (chronic tic and/or obsessive-compulsive disorder with no known temporal relationship to group A beta-hemolytic streptococcus infection).

    To determine if a single daily dose of cefadroxil would be effective in the treatment of group A beta-hemolytic streptococcal (GABHS) pharyngitis, 196 patients with GABHS pharyngitis were randomly assigned to receive either penicillin V 250 mg three times daily or cefadroxil 30 mg/kg once daily, for 10 days. Outcome was measured by the ability to isolate GABHS from the upper respiratory tract 18 to 24 hours after the onset of therapy, the impact on the clinical course, and the ...

    Evidence of acute glomerulonephritis developed in twenty-five persons following the reintroduction of type 49 streptococci at the Red Lake Indian Reservation in 1966. All recognized cases occurred in children less than ten years of age. Cases were evenly divided between the sexes, but the age distribution was younger for male than for female patients. In several patients nephritis developed despite penicillin therapy. One patient had had a well documented previous attack of acute ...
