Abstract

OBJECTIVE:

To evaluate how common pharyngeal Chlamydia trachomatis (CT) is among mainly heterosexual women and men with a confirmed or a highly suspicious genital infection having had recent unprotected active oral sex.

DESIGN:

Prospective observational study.

SETTING:

Out-patient clinics for sexually transmitted infections in Stockholm.

POPULATION:

A total of 143 women and 138 men with a confirmed or suspected genital CT infection and a history of active oral sex.

METHODS:

Pharyngeal samples from men and women in the study population were analyzed for the presence of CT.

MAIN OUTCOME MEASURES:

Number of positive CT in pharyngeal samples in relation to positive CT in genital samples.

RESULTS:

Of the women, 9/128 (7.0%) were positive in the pharyngeal samples. None were exclusively positive in the pharynx. Three of 110 men (2.7%) had pharyngeal involvement. One man was positive in the pharynx as well as in the urine sample, and two men were exclusively pharyngeal CT positive.

CONCLUSIONS:

The finding of CT in the pharynx is not common in spite of the presence of a genital infection and a history of active oral sex.
