Asymptomatic pharyngeal carriage of beta-haemolytic streptococci and streptococcal pharyngitis among patients at an urban hospital in Croatia.

In a one-year study at the University Hospital of Infectious Diseases in Zagreb, Croatia the rate of asymptomatic throat carriage of beta-haemolytic streptococci was investigated. Throat carriage was investigated in 1796 patients, none of whom had a sore throat nor signs and/or symptoms of a respiratory tract infection. The carrier rate of beta-haemolytic streptococci was 8.3%, for group A streptococci 6%, group B 1.3%, group C 0.3% and group F 0.1%. The highest rate was observed in the 6 to 14 year age group: 13.8% for all streptococcal groups, 11.7% for group A alone. The proportion of non-A streptococci was higher in older age groups. Tonsillectomised individuals were less frequently carriers. No sex or season-dependent variations were observed. In a four-month study of 629 patients with pharyngitis the throat cultures yielded: group A streptococci in 44.7%, group B in 1.7%, group C in 0.8%, and group G in 0.6% of the patients. Group A streptococci in 44.7%, group B in 1.7%, group C in 0.8%, and group G in 0.6% of the patients. Group A streptococcal rates in carriers compared to rates in patients with pharyngitis suggest that approximately one fourth of the schoolchildren with culture-positive pharyngitis actually are not truly infected, but only carriers currently having a sore throat of non-streptococcal etiology. Antibiotics were administrated to 605 (96.2%) patients with pharyngitis; in 571 (94.4%) of the cases before culture results became available. After culture-negative results were obtained the therapy was discontinued in only 28.5% of the cases.(ABSTRACT TRUNCATED AT 250 WORDS)

[Bacteremia caused by beta-hemolytic group A streptococci].

The epidemiological, clinical and laboratory characteristic of group A beta-hemolytic streptococcal (GABHS) bacteremia in patients treated at the University Hospital of Infectious Diseases in Zagreb were analyzed. Of 51 cases of bacteremia due to GABHS seen over the past 15 years, 15 (29%) have been registered since 1987. The mean age of our patients was 25 years (range, 5 months to 87 years); and 29 (57%) were under 18. Ten (19%) patients died, 6 being less than 18 years of age. Forty-seven (92%) cases were community-acquired and 16 (32%) had underlying disease. Primary foci of infection, defined as a sites of inflammation that precedes bacteremia, included pharyngitis in 15 and erysipelas/cellulitis in 16 patients. Six patients had no focus of infection. Shock was recorded in 4 patients, all of whom died. Seven patients had a rash, in 5 the rash was typical of scarlet fever. Of the 6 children who died 4 were previously healthy and they all died within 24 hours following admission, and were sick at least 48 hours before admission to our hospital. Our experience suggests that serious GABHS infections may appear in children, that it requires prompt recognition and treatment and that a worldwide change in the virulence of GABHS may have occurred.
