Abstract
To review the characteristics of reported outbreaks of acute rheumatic fever in the United States, and to determine if there is an increase in the incidence of acute rheumatic fever in the population served by the Hospital for Sick Children, Toronto, Ontario, the authors conducted a literature search and a retrospective review of inpatients and outpatients, satisfying the revised Jones criteria for the diagnosis of acute rheumatic fever, from 1972 to 1988. Patients satisfying the revised Jones criteria for the time period 1972-88 were included in the study. There have been eight articles reporting an increase in acute rheumatic fever in the United States. In three, the majority of children were white and from middle class suburban/rural communities in different geographic locations. Mucoid strains of group A streptococci were implicated but not confirmed as being associated with the outbreaks in three. The results of the chart review at the Hospital for Sick Children revealed that 83 cases satisfied the revised Jones criteria. The number of cases per 100,000 children (aged 18 years or less) per year, decreased progressively over the study period. Polyarthritis was the most frequently seen major criterion occurring in 73% of patients (61 of 83). The most frequently affected ethnic groups were Italians 23%, Afro-Canadians 19% and Orientals 8%. The reported outbreaks in the United States are multifocal and predominantly confined to white middle class children residing in suburban/rural communities. There was no evidence of an increase in the number of cases of acute rheumatic fever seen in the population served by the Hospital for Sick Children; there was a progressive decline in number of cases over the study period. The results facilitate the characterization of acute rheumatic fever within North America into three different patterns of occurrence.

Abstract
Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) are significant public health concerns around the world. Despite decreasing incidence, there is still a significant disease burden, especially in developing nations. This review provides background on the history of ARF, its pathology and treatment, and the current reported worldwide incidence of ARF and prevalence of RHD.

Abstract
OBJECTIVE The goal was to describe characteristics of children discharged from hospitals in the United States in 2000 with the diagnosis of acute rheumatic fever. METHODS We explored characteristics of children <21 years of age who were hospitalized with a diagnosis of acute rheumatic fever by using the 2000 Kids' Inpatient Database, weighted to estimate the number and rate of acute rheumatic fever-associated hospitalizations in the United States. RESULTS In 2000, an estimated 503 acute rheumatic fever hospitalizations occurred among children <21 years of age, at a rate of 14.8 cases per 100,000 hospitalized children, with a mean age of 10 years. In comparison with all Kids' Inpatient Database admissions, acute rheumatic fever hospitalizations were more common in the age group of 6 to 11 years and among male patients. Chorea was more common in female patients (61.7%). White patients were significantly underrepresented, whereas Asian/Pacific Islander patients and patients of other races were overrepresented. Hospitalizations of patients with acute rheumatic fever were significantly more common in the Northeast and less common in the South. The highest rates of acute rheumatic fever hospitalizations occurred in Utah, Hawaii, Pennsylvania, and New York. Significantly more acute rheumatic fever admissions occurred in March. The expected payor was more likely to be private insurance and less likely to be Medicaid. Acute rheumatic fever hospitalizations were more likely to occur in teaching hospitals, freestanding children's hospitals, and children's units in general hospitals and in urban locations. The median length of stay for acute rheumatic fever hospitalizations was 3 days, and the median total charges were $6349. The in-hospital mortality rate was 0.6%. CONCLUSIONS In 2000, we found that hospitalizations for acute rheumatic fever were infrequent and varied according to race, season, location, and type of hospital.

Group A Streptococcal Isolates Temporally Associated with Acute Rheumatic Fever in Hawaii: Differences from the Continental United States. Clin Infect Dis 2007; 45:e20-4.

Abstract
BACKGROUND The annual incidence of acute rheumatic fever (ARF) in Hawaii has remained several times higher than that in the continental United States, particularly among ethnic Polynesians. The emm types of Streptococcus pyogenes that are associated with this nonsuppurative complication have, to our knowledge, not been previously reported in Hawaii. METHODS Patients with ARF were identified through an active surveillance system at Kapiolani Medical Center (Honolulu, HI), the only pediatric tertiary care referral hospital in Hawaii. Specimens were obtained by throat culture from patients who met the Jones criteria for ARF at the time of presentation (63 patients), prior to penicillin treatment, and from consenting family contacts (10 individuals). Eight patients and 2 close family contacts with positive throat culture results were identified from February 2000 through December 2005. Group A streptococci isolates were characterized by emm sequence typing. RESULTS Unusual emm types were temporally associated with the onset of ARF. Emm types 65/69 (from 2 patients), 71, 92, 93, 98, 103, and 122 were isolated from the 8 patients with ARF, and emm types 52 and 101 were isolated from the 2 household contacts. CONCLUSIONS So-called rheumatogenic emm types and/or serotypes, which were previously associated with ARF in the continental United States, were not found in this study. Instead, emm types that are not commonly included among group A streptococci isolates in the continental United States and that are seldom, if ever, temporally associated with ARF were identified. These findings suggest that unusual group A streptococci emm types play a significant role in the epidemiology of ARF in Hawaii.

Abstract
The outcome of cephalosporin versus penicillin treatment of group A streptococcal tonsillopharyngitis may differ between Europe and the USA. In the present study, Medline, Embase, reference lists, and abstract searches were used to identify randomized, controlled trials of cephalosporin versus penicillin treatment of group A streptococcal (GAS) tonsillopharyngitis. The outcomes of interest were bacteriologic and clinical cure rates from investigations conducted in Europe versus those conducted in the USA. Forty-seven trials involving 11,426 patients were included in the meta-analyses. For the comparison of 10 days of treatment with cephalosporins versus 10 days of treatment with penicillin, there were ten European and 25 U.S. trials, all involving pediatric subjects. The overall odds ratio (OR) favored cephalosporins more strongly in bacteriologic cure rate in Europe (OR=4.27, p<0.00001) than in the USA (OR=2.70, p<0.00001). Studies of 4-5 days of cephalosporin treatment versus 10 days of penicillin treatment were also analyzed. For nine European trials, the OR significantly favored cephalosporins (OR=1.30, p=0.03) in bacteriologic cure rates, but not as strongly as in the USA, (OR=2.41, p<0.00001). When results for 4-5 days of cephalosporin treatment were divided into pediatric versus adult populations, the differences in bacteriologic eradication rates obtained with cephalosporins were more pronounced in children. The likelihood of bacteriologic and clinical failure of GAS tonsillopharyngitis treatment in both European and U.S. patients is significantly less if a 10-day course of oral cephalosporin is prescribed, and is at least similar, if not significantly less, with a 4- to 5-day course of oral cephalosporin compared with a 10-day course of oral penicillin.

Abstract
BACKGROUND The explanation for the very substantial decrease in the incidence of acute rheumatic fever in the United States, particularly over the past 50 years, is unclear. It has been proposed that certain M types of group A streptococci (GAS) include strains that are particularly rheumatogenic and that others are nonrheumatogenic. METHODS We compared the M type distribution of GAS recovered from children from Chicago, Illinois, with acute pharyngitis during 1961-1968 to that of GAS recovered from Chicago children and children from across the United States in 2000-2004, with attention to changes in M types that previously were associated with rheumatogenic strains. RESULTS The rheumatogenic types 3, 5, 6, 14, 18, 19, and 29 comprised 49.7% of 468 pharyngeal isolates during 1961-1968 but only 10.6% of 450 Chicago isolates during 2000-2004 (P < .001) and 17.9% of 3969 isolates nationwide during 2000-2004 (P < .001). Significant decreases in types 3, 5, and 6 and virtual disappearance of types 14, 18, 19, and 29 occurred between the 2 study periods. No change in the proportion of type 1 isolates, a highly heterogeneous group that includes some rheumatogenic strains, was observed. The nonrheumatogenic GAS types 2, 4, 22, and 28 increased from 4.9% to approximately 28% of pharyngeal isolates in Chicago and nationwide between the 2 study periods (P < .001). CONCLUSIONS These data support the concept of rheumatogenic strains of GAS and indicate that the marked decrease in the incidence of acute rheumatic fever in the United States over the past 4 decades is correlated with the replacement of rheumatogenic types by nonrheumatogenic types in cases of acute streptococcal pharyngitis in children. The reasons underlying the observed change in distribution of M types remain to be elucidated.

Abstract
OBJECTIVE Our objective was to confirm an observed temporal association of increased numbers of rheumatic fever cases concomitant with the appearance of an increased prevalence of mucoid strains of Streptococcus pyogenes. During the resurgence of rheumatic fever (RF) that has occurred in the Intermountain area surrounding Salt Lake City, Utah, since 1985, the largest number of cases occurred in 1985 and 1986 and 12 years later in 1997 and 1998. During the initial outbreak and the later exacerbation of the resurgence, an increased number of mucoid strains of S pyogenes were present in the community. METHODS The referred cases of RF that fulfilled Jones criteria have been systematically reviewed by the medical staff at Primary Children's Medical Center yearly since 1985. Before the resurgence of RF, a program was initiated by the microbiology laboratory at Primary Children's Medical Center to store frozen isolates of S pyogenes. All frozen specimens were randomly selected and entered into a log; the coded entry allowed for comments regarding the origin of the isolate and whether the isolate had a mucoid appearance on the blood agar culture plate. This log was reviewed in October 2002 to determine whether the percentage of frozen mucoid isolates stored during the resurgence of RF would support the clinical and epidemiologic suspicion that mucoid isolates seemed to be present with a higher frequency during the 2 periods of high incidence of RF. The percentage of mucoid isolates was compared with the yearly number of cases of RF. A Pearson r correlation analysis was completed to determine whether there was a significant association between the percentage of mucoid isolates and the number of cases of RF. RESULTS The highest number of cases of RF was temporally associated with the highest percentage of mucoid isolates. There was statistically significant correlation between percentage of mucoid strains and the number of RF cases. CONCLUSIONS The Utah experience with the resurgence of RF in a civilian population during the last decade and a half of the 20th century confirmed the temporal association of mucoid strains of S pyogenes, primarily M-type 18, with a high incidence of RF.

Abstract
Benzathine penicillin G (BPG) is effective for secondary prophylaxis of rheumatic fever (RF). However, interval between injections a remains a controversial matter. In a study population of 74 patients, following the initial diagnosis of RF, 3-weekly BPG (1.2 million units) regimen was started. During the first three-week period, serum penicillin concentrations were examined on the 7th, 14th and 21st days and throat culture done for group-A b hemolytic streptococcal (GABHS) infection. Ten patients (13.5%) at 21st day of injection had low serum penicillin concentration after the first BPG. GABHS was isolated in 5 patients during this period. Although two of these 5 patients had symptoms of respiratory tract infection, according to laboratory data, the other three were accepted as carriers. All 74 patients were then followed-up for rheumatic recurrence (RR) during long-term period (6 to 60 months, mean 25 +/- 5 months). There was no RR among regular (missing no more than one injection a year) group. We concluded that 3-weekly BPG regimen was satisfactory for secondary prophylaxis in RF, even though serum penicillin level was inadequate during the third week in some of the patients.

Abstract
To describe the epidemiology and clinical features of Sydenham's chorea in the Aboriginal population of northern Australia a review was conducted of 158 episodes in 108 people: 106 were Aborigines, 79 were female, and the mean age was 10.9 years at first episode. Chorea occurred in 28% of cases of acute rheumatic fever, carditis occurred in 25% of episodes of chorea, and arthritis in 8%. Patients with carditis or arthritis tended to have raised acute phase reactants and streptococcal serology. Two episodes lasted at least 30 months. Mean time to first recurrence of chorea was 2.1 years compared with 1.2 years to second recurrence. Established rheumatic heart disease developed in 58% of cases and was more likely in those presenting with acute carditis, although most people who developed rheumatic heart disease did not have evidence of acute carditis with chorea. Differences in the patterns of chorea and other manifestations of acute rheumatic fever in different populations may hold clues to its pathogenesis. Long term adherence to secondary prophylaxis is crucial following all episodes of acute rheumatic fever, including chorea, to prevent recurrence.

Abstract
There is an increasing occurrence of reactive group A beta haemolytic streptococci (BHS) phenomena. This review makes a case for considering BHS in the differential diagnosis of adult reactive arthritis. This is based on (a) published reports over the past 45 years describing first attacks of rheumatic fever in adults; (b) the longstanding observation that polyarthritis is the most commonly expressed Jones major criterion in adults; (c) the broad spectrum of clinical expression of disease following streptococcal infection, with the re-emergence of the term 'poststreptococcal reactive arthritis'. The arthritis in adult rheumatic fever is characterised by sequential involvement of large weightbearing joints. Recurrent, severe, prolonged arthritis has been a prominent feature of adult poststreptococcal reactive arthritis. Carditis has been reported in 33% of adult patients with rheumatic fever. Consequently long term antibiotic prophylaxis for adults with reactive BHS phenomena should be strongly considered, and guidelines are suggested for this in individual patients. Further areas for research are discussed, particularly the interrelations between bacteria and host in disease expression, and the possibility that BHS might play a part in chronic arthritides and vasculitides.

Abstract
OBJECTIVE To evaluate treatment of group A beta haemolytic streptococcal pharyngitis with amoxycillin once daily compared with phenoxymethylpenicillin three or four times a day. DESIGN Randomised controlled study of consecutive patients presenting with symptoms suggestive of group A beta haemolytic streptococcal pharyngitis in whom culture of a throat swab yielded positive results. SETTING Five family medicine practices. SUBJECTS 157 patients aged over 3 years who required treatment with antibiotics. MAIN OUTCOME MEASURES Clinical response, bacteriological response, days at work and school lost, and compliance. RESULTS During the period of the study 393 patients presented with symptoms suggesting streptococcal pharyngitis; 157 of them had throat swabs that yielded positive results on culture. Eighty two were treated with phenoxymethylpenicillin and 75 with amoxycillin. No difference was observed in the clinical response, days at work and school lost (139 days for 64 patients taking phenoxymethylpenicillin v 100 days for 57 patients taking amoxycillin; p > 0.2), or residual positive cultures after two days (6 (7.3%) v 3 (4%); p > 0.5). A significant difference in the bacteriological response was found after 14 days (5 (6.1%) v 0; p < 0.04) with no positive cultures observed in the amoxycillin group. CONCLUSIONS These findings support the hypothesis that amoxycillin once daily is as effective as phenoxymethylpenicillin in the treatment of group A beta haemolytic streptococcal pharyngitis.

Abstract
Pyrogenic exotoxins A, B, and C produced by group A beta-hemolytic streptococci (Streptococcus pyogenes) may cause a syndrome characterized by fever, rash, desquamation, hypotension, and multi-organ-system dysfunction. This syndrome, the streptococcal toxic shock-like syndrome (TSLS), has a rapid and fulminant course closely resembling the staphylococcal toxic shock syndrome (TSS) caused by the staphylococcal toxic shock syndrome toxin-1 (TSST-1). The recent recognition of this syndrome is thought to stem from the appearance of more virulent strains of streptococci that have a greater tendency to produce potent exotoxins than prior strains. During the past 6 years, the authors have treated six patients with TSLS; three of these patients have presented recently. The sites of streptococcal infection associated with the development of the syndrome are frequently in soft tissue and skin. Early diagnosis, treatment with penicillin, and radical operative debridement are required.

Abstract
Several areas in the United States have experienced significant outbreaks of acute rheumatic fever. Reasons for the reappearance of acute rheumatic fever are incompletely understood but may relate to changes in the organism. Fortunately, however, GABHS has remained exquisitely susceptible to penicillin. Given the resurgence in cases of acute rheumatic fever, the practicing physician needs to be vigilant in diagnosing and ensuring adequate treatment of acute streptococcal pharyngitis. In addition, acute rheumatic fever must be considered in a patient who presents with a new onset murmur, a migratory polyarthritis, chorea, or a rash suggestive of erythema marginatum.

Abstract
Rheumatic fever is still one of the major public health problems in Egypt and the developing countries. It is characterized by a high tendency to recur following streptococcal infections. The use of long acting penicillin for prophylaxis against strep infections was a good achievement in this field, yet, recurrences have been reported in patients following monthly prophylactic programs. Clinical experience in Alexandria have shown for a long time that giving penicillin every 2 weeks is followed by less recurrences of rheumatic fever. Recently, reports came showing that effective penicillin levels are not maintained except for 2 to 3 weeks after the injection. In the present study, we compared two regimens of prophylaxis with 190 patients in the 2-weekly regimen, and 170 patients in the 4-weekly regimen being followed up for 2 consecutive years. Two hundred and sixty nine streptococcal infections occurred during this period. Although the streptococcal infection rate was equal in both groups, the rheumatic fever recurrence rate and the RF attack rate were significantly higher in the group of patients on the 4-weekly schedule. The results of this study have shown the superiority of the 2-weekly schedule in the adequate control of RF recurrences. We suggest that this schedule should be implemented for secondary prophylaxis of rheumatic fever in Egypt and other areas with severe RF.

Abstract
The clinical and laboratory data for an 8 year old girl with abdominal pain as a presenting manifestation of acute rheumatic fever are reported. An abdominal investigation with ultrasonography carried out at the same time showed free peritoneal fluid. These findings support the proposal that the abdominal pain classically described in acute rheumatic fever is one of the manifestations of the inflammatory process. It is suggested that in patients with abdominal pain, fever, and increased erythrocyte sedimentation rate in whom the diagnosis is not clear, an abdominal investigation with ultrasonography could be helpful in establishing the correct diagnosis.

Acute pharyngitis is frequently encountered in the ambulatory care setting. Although usually of viral etiology, streptococcal disease is the focus of diagnostic efforts, in light of significant suppurative and nonsuppurative sequelae. The traditional symptoms of fever, adenopathy, and pharyngeal exudate are suggestive, but not diagnostic of streptococcal pharyngitis. Thus, the importance of diagnostic testing, including Group A beta hemolytic strep antigen screen and culture, is emphasized. Recent innovations in therapy include modification of antibiotic dosing regimens and use of cephalosporins to improve patient compliance.

Abstract
Mucoid strains of group A Streptococcus have been associated with recent outbreaks of acute rheumatic fever. The mucoid colony morphology of these strains is a result of abundant production of capsular polysaccharide, which is composed of hyaluronic acid. To study the role of the hyaluronic acid capsule in virulence, we derived an acapsular mutant from a mucoid strain of group A Streptococcus by transposon mutagenesis. M protein expression was not altered in the mutant strain. The mucoid wild-type strain grew in fresh human blood and was resistant to phagocytic killing in vitro. In contrast, the acapsular mutant failed to grow in fresh human blood and was sensitive to phagocytic killing in vitro. Loss of capsule was associated with a 100-fold reduction in virulence of the organisms in mice. We conclude that the hyaluronic acid capsule protects mucoid group A streptococci from phagocytosis and has an important role in virulence.

Abstract
The authors have evaluated the incidence of Group A streptococci, and the prevalence of erythromycin-resistant strains in the years 1985/86/87 at the I.C.P. of Milan. The minimum inhibitory concentrations (MICs) for erythromycin, penicillin and miocamycin of 40 erythromycin-resistant strains were also studied (MIC50-MIC90 = 4.5-8, 0.015-0.015, 0.041-0.186 micrograms/ml respectively). A clinical trial with miocamycin vs. erythromycin in the elimination of Group A streptococci (67 patients) showed good and comparable efficacy for both the antibiotics.
