Most sore throats (pharyngitis)are viral and will not respond to antibiotics. Bacterial causes of sore throat include group A streptococcus. The complications of strep throat include rheumatic fever, ear infections, mastoiditis, sinusitis, peritonsillar abscess, glomerulonephritis (a kidney disorder), and scarlet fever.
Diagnosis of Strep Throat
When a childhas a sore throat, arapid antigen testshould bedone for strep, according to Dr. Warren J. McIsaac and colleagues in Canada. If the rapid test is positive, thechild (or adult) should betreated with an antibiotic. If the rapid test is negative, a throat culture may be done. (This takes more time, usually overnight.)
Treatment of Strep Throat
The cephalosporin antibiotics such as cephalexin (Keflex, Keftabs, Biocef) and cefadroxil (Duricef)are about three times more effective --three times lesslikely to fail --in eradicating strep than penicillin. This conclusion is based ona meta-analysis of 35trials reportedby Drs. Janet R. Casey and Michael E. Pichichero from the University of Rochester.
