Comparison of Efficacy of Two Combination Regimens for the Neisseria Gonorrhoeae and Chlamydia Coinfection

Overview

The frequency of Chlamydia trachomatis and Neisseria gonorrhoeae coinfection can vary depending on their individual incidence and prevalence rates.Single-agent therapy with ceftriaxone is the preferred regimen for treatment of gonococcal infections. If an injectable cephalosporin is not available, cefixime is the only oral cephalosporin that can be used for gonococcal therapy. Doxycycline was recommended for presumptive treatment of chlamydia in nonpregnant individuals with gonococcal infection. The study is conducted to evaluate the effectiveness of two regimens in combination with doxycycline with cefixime or ceftriaxone.

Gonococcal infections, including urethritis, cervicitis, epididymitis, and proctitis, are a significant cause of morbidity among sexually active men and women. The treatment of these sexually transmitted infections (STIs) has evolved over the years, mainly due to the emergence of antibiotic resistance. The frequency of Chlamydia trachomatis and Neisseria gonorrhoeae coinfection can vary depending on their individual incidence and prevalence rates. Ceftriaxone is highly effective against susceptible N. gonorrhoeae. Single-agent therapy with ceftriaxone is the preferred regimen for treatment of gonococcal infections. These doses of ceftriaxone are higher than previously recommended due to concerns regarding rising gonococcal minimum inhibitory concentrations (MICs) worldwide. If an injectable cephalosporin is not available, cefixime is the only oral cephalosporin that can be used for gonococcal therapy. Doxycycline (100 mg orally twice daily for seven days) was recommended for presumptive treatment of chlamydia in nonpregnant individuals with gonococcal infection. The study is conducted to evaluate the effectiveness of two regimens in combination with doxycycline with cefixime or ceftriaxone.
