Comparison of anti Chlamydia antibodies in tubal and non-tubal infertile patients
Abstract
Background and purpose: Chlamydia trachomatis infection is one of the most prevalent bacterial sexually transmitted infection in most countries. This organism may stay in genital tract for long time and cause subtle yet progressive damage in fallopian tubes. In this study we evaluate the correlation between chlamydia antibodies and tubal and other factors of infertility.Materials and Methods: In this case control study, 28 patients with tubal factor infertility, 28 patients with non tubal factor infertility and 30 normal patients were enroled. Presence or absence of tubal factor was assessed by direct vision via laparscopy, then titres of IgA and IgG were evaluated in all of them using ELISA method in the same labratory. Data were recoded and analyzed using SPSS software and chi-square, Fisher's exact, T-test and Mann- Whitney test.Results: Positive titre of IgG was higher in tubal factor infertility but it was not statistically significant between three groups (p>0.294). Positive titres of IgA were more common in non tubal factor infertility (p=0.007). Though positive and negative titres of IgA (P=0.224) and IgG (P=0.273) were not statistically different in fertile and infertile patients. Positive and negative titres of IgA and IgG were also not statistically different in patients with or without PID (p>0.05).Conclusion: No correlation was found between the positive titres of IgG and IgA against Chlamydia and tubal factor infertility.
