Streptococcal pharyngitis in general practice. 2. A note on dual infection and transient urinary abnormalities

Abstract

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.

Streptococcal pharyngitis in general practice. 1. Some unusual features of the epidemiology

“…Swabs were taken for culture of bacteria in all cases and in some for culture of viruses also. For a period of 12 months up to mid-December 1965 all patients of mine with acute infections of the upper respiratory tract were recruited into a study of transient urinary abnormalities following acute sore throat [1]. This paper reports the epidemiological findings, supplemented by data recorded in 1963 and 1964 and the results of a study of acute sore throat in all patients of the practice in 1959 [2].…”

Acute poststreptococcal glomerulo-nephritis in general practice: the contribution of infection to its onset and course

“…It is possible that in some or in all the sore throat was due to a virus infection occurring in a person with a subclinical streptococcal infection. Dual infection may increase the risk of developing haematuria [29].…”
