Correlation of Chlamydia IgG Antibodies with Hysterosalpingogram and Laparoscopy

Area of Science:

• Gynecology
• Radiology
• Infectious Disease

Background:

• Pelvic inflammatory disease (PID) can lead to long-term reproductive complications.
• Chlamydia trachomatis is a common cause of PID, often presenting asymptomatically.
• Hysterosalpingography (HSG) is a key imaging modality for evaluating the female reproductive tract.

Purpose of the Study:

• To investigate the association between Chlamydia IgG antibodies and specific findings on hysterosalpingography (HSG).
• To determine the diagnostic value of HSG in identifying pelvic pathology in women.
• To assess the correlation between HSG findings, Chlamydia IgG status, and laparoscopic diagnoses.

Main Methods:

• Retrospective review of 108 hysterosalpingograms (HSG) from women who also underwent laparoscopy.
• Gynecologist and radiologist independently reviewed HSG images, blinded to clinical and laparoscopic data.
• Analysis of the association between positive Chlamydia IgG, HSG findings (including 'corkscrew' appearance), and laparoscopic diagnoses (hydrosalpinges, salpingitis isthmica nodosa, adhesions, endometriosis).

Main Results:

• Positive Chlamydia IgG was significantly associated with hydrosalpinges and salpingitis isthmica nodosa.
• A positive HSG for 'corkscrew' findings was not statistically significant with positive IgG.
• 'Corkscrew' appearances on HSG were not specific for adhesions or endometriosis.
• Positive IgG and positive HSG together suggest Chlamydia infection and can indicate increased risk for pelvic pathology.
• A notable 48% incidence of pelvic adhesive pathology was observed even in patients with negative IgG and negative HSG.

Conclusions:

• Chlamydia IgG positivity correlates with specific HSG findings indicative of tubal damage.
• HSG is a valuable tool for risk stratification of pelvic pathology, particularly when Chlamydia infection is suspected.
• The absence of Chlamydia IgG and negative HSG does not rule out significant pelvic adhesive disease, highlighting the complexity of reproductive health issues.
