Laparoscopic study on the microbiology and severity of acute pelvic inflammatory disease
1Department of Clinical Medicine, University of Tampere, Finland.
Objective:
To study the microbiologic findings in relation to the severity of acute pelvic inflammatory disease (PID).
Study Design:
Of 72 women with acute PID verified and graded by laparoscopy and endometrial histopathology, 37 had mild PID and 35 had severe PID. Cervical, endometrial and tubal cultures were obtained for Chlamydia trachomatis, Neisseria gonorrhoeae, genital mycoplasmas, facultative and anaerobic bacteria and herpes simplex virus.
Results:
C. trachomatis was the primary pathogenic agent in 44% of patients with acute PID. C. trachomatis and N. gonorrhoea were as common in both severity groups, although C. trachomatis was isolated significantly more frequently from the fallopian tubes among cases with severe PID. Where aerobic or facultative bacteria other than C. trachomatis or N. gonorrhoeae were concerned, Escherichia coli and Haemophilus influenzae were the most important aerobic bacteria isolated from the fallopian tubes. Anaerobic bacteria were recovered from the fallopian tubes significantly more frequently in cases with severe PID than in those with mild PID, whereas their presence in the endometrium was not related to the severity of PID.
Conclusions:
The role of C. trachomatis as the leading cause of PID was confirmed in both laparoscopically mild and severe PID. Severe PID with abscess is invariably a polymicrobial infection with anaerobic bacteria involved, whereas their role in affecting the outcome of mild PID as well as the need of antianaerobic antimicrobial therapy in mild PID remains questionable.
Insights
Chlamydia trachomatis is a primary cause of pelvic inflammatory disease (PID). Severe PID involves anaerobic bacteria, while their role in mild PID requires further study.
Area of Science:
- Gynecology
- Infectious Diseases
- Microbiology
Background:
- Pelvic inflammatory disease (PID) is a significant gynecological infection.
- Understanding the causative agents and their relation to disease severity is crucial for effective treatment.
Purpose of the Study:
- To investigate the microbiological findings associated with the severity of acute pelvic inflammatory disease (PID).
Main Methods:
- Laparoscopy and endometrial histopathology were used to grade PID severity in 72 women.
- Cervical, endometrial, and tubal cultures were analyzed for various pathogens, including Chlamydia trachomatis, Neisseria gonorrhoeae, and bacteria.
Main Results:
- Chlamydia trachomatis was identified as the primary pathogen in 44% of PID cases.
- Anaerobic bacteria were significantly more prevalent in the fallopian tubes of women with severe PID compared to mild PID.
- Escherichia coli and Haemophilus influenzae were key aerobic bacteria found in severe PID fallopian tubes.
Conclusions:
- Chlamydia trachomatis is a leading cause in both mild and severe PID.
- Severe PID, especially with abscess, is polymicrobial and involves anaerobic bacteria.
- The necessity of antianaerobic therapy for mild PID remains uncertain.
