To determine the frequency of antistreptolysin O (ASLO) positivity in cases of proven chronic tonsillitis.

Materials and methods

The present study was conducted in a tertiary care center from January to October 2013. A total of 150 patients who presented with features suggestive of chronic tonsillitis and willing for surgery were included in the study. On admission, following a detailed history taking and clinical examination, preoperative investigations along with ASLO titers were done. Following medical and anesthetic fitness, the patients underwent tonsillectomy with or without adenoidectomy and the tonsillar specimens were sent for histopathological examination.


A total of five out of the 150 patients showed ASLO titer positivity (>200 IU/ml) and all were histopathologically proven cases of chronic tonsillitis.


Early detection and treatment of Streptococcal tonsillar involvement could be a preventive measure against the future predilection of other predisposed organs to more severe and debilitating streptococcal infections.
