Renewal of peritonsillar abscess: Impact of the bacterial species of the infection and clinical features of the patient- prospective comparative aetiological study

Abstract

Objectives

To compare the bacterial species and patient clinical features in peritonsillar abscesses between patients who had renewal (renewal group) and those who did not (recovery group).

Design

Prospective comparative aetiological study.

Setting

Tertiary referral centre.

Participants

A total of 180 adult peritonsillar abscess patients were prospectively collected and treated as outpatients with incision and drainage and oral antibiotics. Bacteria from the pus was evaluated with a microarray assay. All contact with the health care system and renewal of the symptoms were recorded.

Main outcome measures

Different bacterial species and patient clinical features between the renewal and recovery groups.

Results

Of the 180 enrolled patients, 18 experienced a renewal of symptoms. Bacteria from the Streptococcus anginosus group was detected in the patient samples of the renewal group more often than the recovery group (p=0.002). No isolated Streptococcus pyogenes samples were reported in the renewal group, while in the recovery group it was reported on 24% of the patients (p=0.014). In the renewal group, patients over age 40 experienced symptom renewal faster than the younger patients (p=0.013) and were more likely to be male (p=0.036).

Conclusions

Bacteria in the Streptococcus anginosus group appear to predict renewal of PTA symptoms, while Streptococcus pyogenes was not found in our patients with symptom renewal. Certain subgroups of patients should be followed more closely.
