BACKGROUND: The purpose of this study was to determine whether gastrointestinal (GI) symptoms are more common in streptococcal than @entity7551 , and, if so, whether these symptoms are useful diagnostic predictors. METHODS: @entity1 aged 4 and older presenting consecutively to one of three family practice clinics and one emergency department with the chief complaint of sore throat were invited to participate in the study. A nurse administered a brief symptom checklist; after documenting clinical signs, the clinician assessed and treated the @entity1 . All @entity1 were screened for group A streptococcus using the Abbott Test Pack Plus. @entity1 were enrolled from January 1996 through March 1996. Significant associations of signs and symptoms with @entity883 were determined by chi square, likelihood ratios were calculated, and logistic regression was used to compare diagnostic prediction models with and without GI symptoms. RESULTS: Six hundred fifty-seven consecutive @entity1 with the presenting complaint of sore throat were enrolled in the study. The mean age of the @entity1 enrolled was 19 years; the median age was 14. Thirty-two percent of the @entity1 (ages 4 to 18), 23% of the adults (ages 19 to 74), and 29% of all @entity1 had @entity883 . Symptom frequencies for streptococcal and @entity7551 , respectively, were: @entity390 (39% vs 31%, P = .14); @entity391 (14% vs 7%, P = .004); @entity490 (27% vs 26%, P = .621); and any GI symptom (47% vs 41%, P = .45). When included in a predictive model with other significant predictors of @entity883 including age, palatal petechiae, absence of cough, and anterior cervical adenopathy, the addition of @entity390 or @entity391 added slight predictive power to the models, but @entity490 and "any GI symptom" did not. CONCLUSIONS: @entity390 and @entity391 are somewhat more common in streptococcal than in @entity7551 , but appear to have limited usefulness as clinical predictors of @entity883 .
