Febrile exudative tonsillitis: viral or streptococcal?

A prospective 1-year study of acute febrile exudative tonsillitis in 110 children was carried out. Viral infection was associated with 42% of the cases, beta-hemolytic streptococci with 31% (12% group A), Mycoplasma pneumoniae with 5%, and unknown cause with 35%. More than one agent was implicated in 14% of the cases. Adenovirus was the viral agent most frequently (19%) recorded. Other viruses involved were Epstein-Barr virus, parainfluenza, influenza A, herpes simplex, and respiratory syncytial viruses. The responsible agent was found by rapid viral antigen detection in 20% of all cases and by rapid test for group A streptococcal antigen detection in 10%. Age was the most important factor in predicting the causative agent. Viral tonsillitis was most common in children younger than 3 years of age and group A beta-hemolytic streptococci tonsillitis in children 6 years of age or more. Clinical analysis of the illness, WBC count, and ESR did not reveal differences that could help in differentiating bacterial from viral tonsillitis. All patients were treated with a regimen of oral penicillin. Fever associated with group A beta-hemolytic streptococci tonsillitis responded to penicillin therapy significantly more rapidly than fever associated with viral infections. These observations demonstrate the prominent role of viruses in the etiology of febrile exudative tonsillitis, especially in young children, and reinforce the benefit of rapid tests before antibiotic therapy is started.

Fever in respiratory virus infections.

The case records of 258 children with adenovirus; influenza A or B virus; parainfluenza 1, 2, or 3 virus; or respiratory syncytial virus infections were studied retrospectively with special attention to the degree and duration of fever. A temperature of 39.0 degrees C or higher was most frequently recorded in adenovirus, influenza A, and influenza B virus infections (in 68%, 84%, and 65%, respectively). The mean highest degree of fever in respiratory virus infections (39.2 degrees C +/- 0.6 degrees C) during hospitalization did not differ from that in defined serious bacterial infections, ie, meningitis, epiglottitis, sepsis, and urinary tract infections (39.3 degrees C +/- 0.7 degrees C). The mean duration of fever varied from 2.5 days (parainfluenza 2) to 5.2 days (influenza B). Of all children with respiratory virus infections, 37% had fever lasting five days or longer. The data show that high and prolonged fever is frequently associated with respiratory virus infections in hospitalized children and that it does not differ significantly from fever in severe bacterial infections.

C-reactive protein in the differentiation of adenoviral, Epstein-Barr viral and streptococcal tonsillitis in children.

Sixty-two children with febrile exudative tonsillitis were studied to explore whether quantitative measurements of serum C-reactive protein (CRP) are useful in differentiating viral from streptococcal tonsillitis. There were 23 cases of adenoviral tonsillitis, 21 of EB viral tonsillitis and 18 of streptococcal tonsillitis. Measurements of CRP, WBC counts and erythrocyte sedimentation rates (ESR) were not useful in distinguishing viral from streptococcal tonsillitis. Seventy-four percent of patients with adenoviral tonsillitis were under the age of 3 years and 71% of the patients with Epstein-Barr (EB) viral tonsillitis were under the age of 6 years whereas 72% of the patients with streptococcal tonsillitis were over the age of 6 years. Age was clearly the most important factor in distinguishing between viral and bacterial tonsillitis in children.

C reactive protein in the evaluation of febrile illness.

We studied prospectively 154 febrile children to determine the diagnostic value of the quantitative serum C reactive protein concentrations (CRP). Children with acute otitis media, acute tonsillitis, or treated with antibiotics during the two previous weeks and infants less than 2 months of age were excluded. Ninety seven children were from private paediatric practice and 57 were patients who had been admitted to hospital. The comparison group consisted of 75 children with confirmed bacterial infections whose CRP values were recorded retrospectively. In the study group 35 (23%) children had a confirmed viral infection, 92 (59%) had a probable viral infection as judged from the clinical picture and outcome of the illness, and 27 (18%) had a bacterial or probable bacterial infection. When the duration of the disease was more than 12 hours and the CRP value less than 20 mg/l, all children had a confirmed or probable viral infection. Nine children (one from the study group and eight from the comparison group) were found to have a septic infection and a CRP value of 20 mg/l or less. In all these cases, however, the duration of the symptoms was less than 12 hours. In addition CRP less than or equal to 20 mg/l was found in five (14%) children with urinary tract infection in the comparison group. CRP values of 20-40 mg/l were recorded in children with both viral and bacterial infections. A CRP value greater than or equal to 40 mg/l detected 79% of bacterial infections with 90% specificity. Our data show that determination of serum CRP concentrations is a valuable tool in evaluating children who have been ill for more than 12 hours.
