Chlamydia trachomatis rectal infections were studied in homosexual men. Lymphogranuloma venereum (LGV) strains caused severe proctitis mimicking Crohn's disease, while non-LGV strains caused mild proctitis.

Area of Science:

Proctology
Infectious Diseases
Gastroenterology

Background:

Investigating the prevalence and clinical spectrum of Chlamydia trachomatis rectal infections in homosexual men.
Understanding the histopathological differences between LGV and non-LGV C. trachomatis infections.

Observation:

171 homosexual men were enrolled; 96 symptomatic and 75 asymptomatic.
C. trachomatis was isolated from 14 men.
LGV immunotypes were found in 3 symptomatic men with severe proctitis, showing granulomatous inflammation mimicking Crohn's disease.

Findings:

LGV immunotypes of C. trachomatis are associated with severe acute proctitis.
Non-LGV immunotypes are linked to mild proctitis in both symptomatic and asymptomatic individuals.

Fecal leukocytes and mild mucosal abnormalities were noted in non-LGV infections.

Implications:

LGV rectal infections can present as severe proctitis, potentially misdiagnosed as Crohn's disease.
Distinguishing LGV from non-LGV C. trachomatis is crucial for appropriate patient management.
Highlights the importance of STI screening in at-risk populations.
