SUMMARYIn an uncompleted study in 1965 microscopic haematuria in the second or third week after acute pharyngitis was found four times more often in patients with either microbiological or clinical evidence of dual infection with both group A streptococci and a virus than in patients with evidence only of infection with group A streptococci.Prospective studies of the role of viruses in the aetiology of transient haematuria and of acute post streptococcal glomerulonephritis are feasible in general practice and would be most productive if concentrated in children 5–9 years of age.

SUMMARYThis report is based on a study of acute infections of the upper respiratory tract in 1965 and detailed records of such infections in 1963 and 1964. A change from illnesses mainly yielding viruses to illnesses mainly yielding group A streptococci was noted around the age of 5 years. A positive culture for group A streptococci in patients over 4 years of age was highly correlated with a complaint of sore throat and with serological evidence of streptococcal infection. A bimodal age distribution curve for pharyngitis associated with a positive culture for group A streptococci was consistently noted. The incidence was highest in children aged 5–9 but a second smaller peak occurred among adults in the 30–39 age group. The evidence suggests that being female increases the risk of acquiring group A streptococci and of experiencing sore throat.

Rapid Tests

During the last few years there has been a dramatic proliferation of rapid tests for the diagnosis of group A β-hemolytic streptococcal pharyngitis.1 It is important for physicians to realize that the Food and Drug Administration does not approve these diagnostic tests as it would approve a pharmacologic agent, but simply permits a manufacturer to sell the test. Consequently, unacceptably inaccurate rapid tests for group A streptococci have been marketed in the past and could potentially appear again at anytime. In 1986, we studied a new enzyme fluorescence procedure (Strep-A-Fluor, Bio-Spec Inc, Dublin, CA) for the rapid diagnosis of group A β-hemolytic streptococcal pharyngitis.2

Tract Infections

Beta-hemolytic group A streptococcus (Streptococcus pyogenes) is the most common bacterial agent associated with the upper respiratory tract infections in humans. The most frequently group A streptococcus-associated disease is pharyngitis. Males and females are equally affected by group A streptococcus. There is seasonal increase in the prevalence of group A streptococcus-associated pharyngitis. Streptococcal pharyngitis is most prevalent in winter and early spring with higher incidence of disease observed in crowded population such as school children. Early diagnosis and treatment of group A streptococcal pharyngitis has been shown to reduce the severity of symptoms and further complications such as rheumatic fever and glomerulonephritis. The conventional methods used for identification of group A streptococci depend on isolation and identification of the organism on blood agar plates. These methods usually require 18-24 hours of incubation at 37?C. Such delay in identifying the group A streptococcus has often made physicians to administer therapy without first disclosing the etiological agent. Development of immunologic tests, capable of detecting the group A streptococcal antigen directly from the throat swabs, produced rapid test results employed for better treatment of patients. STREP A test is a rapid immunochromatographic test for the detection of group A streptococci from throat swabs or culture. The accuracy of the test does not depend on the organism viability. Instead, group A strep antigen is extracted directly from the swab and identified using antibodies specific for the group A carbohydrates. We compared rapid test with conventional throat swab in 40 children, who met Centor criteria for streptococcal pharyngitis (absence of cough, high fever, purulent pharyngitis, enlarged and painful cervical lymph nodes). Overall congruence of rapid test and culture was 94%. Test is easy to perform and it is recommended as the first diagnostic test for management of children with streptococcal pharyngitis. In children with negative test, but with characteristics highly suggestive of streptococcal infection, throat culture should be performed.

The relative effectiveness of erythromycin propionate and K penicillin V in two dosage schedules was evaluated in the treatment of 261 cases of acute pharyngitis from which Group A hemolytic streptococci were recovered from December, 1958, to June, 1959. Erythromycin propionate, in a daily dose of 30 mg/kg up to 1.0 gm, and K penicillin V, in daily doses of 375 mg and 750 mg, were administered orally for 10 days. The adjusted bacterial cure rate was 78% among 86 patients treated with erythromycin, 72% among 102 patients treated with K penicillin V, 375 mg, and 88% among 73 patients treated with K penicillin V, 750 mg. The data indicate that K penicillin V was more effective in eradicating Group A streptococci from the pharynx in a daily dose of 750 mg than 375 mg, and suggest that erythromycin propionate in the dosage used, was less effective than K penicillin V, 750 mg, but equally as effective as K penicillin V, 375 mg daily. The incidence, time of occurrence, and results of retreatments of bacterial relapses are presented, and two possible causes of relapses are considered.

SUMMARYThe incidence of beta-haemolytic non-Group A streptococci (BHNAS) in the throats of a paediatric population was examined over a 1-year period. There was minimal seasonal fluctuation of Lancefield groups including species and biotypes within Groups C and G streptococci. A trend of increasing incidence with age ofStreptococcus anginosus(‘Streptococcus milleri’) (possessing Groups C and G Lancefield antigens) was evident. A clinical impression of streptococcal pharyngitis was more common in patients with large-colony Groups C or G streptococci isolated from their throats compared with those patients where other BHNAS were isolated. This study is requisite to the planning of case control studies which are required to test the association of BHNAS (especially Groups C and G subgroups) and pharyngitis.
