A recent study conducted in China has revealed a concerning increase in cases of drug-resistant gonorrhea. The prevalence of ceftriaxone-resistant strains of Neisseria gonorrhoeae, the bacterium that causes gonorrhea, nearly tripled between 2017 and 2021, according to the study published in the CDC's Morbidity and Mortality Weekly Report.

The study surveyed gonorrhea bacterial isolates collected from around the country and found that ceftriaxone-resistant strains accounted for approximately 8 percent of the nearly 3,000 isolates in 2022, up from less than 3 percent in 2017. Although these percentages may seem low, they are significantly higher compared to other countries. In the United States, the prevalence of ceftriaxone-resistant strains never exceeded 0.2 percent during the same period, and in Canada, it remained stable at 0.6 percent. The United Kingdom reported a prevalence rate of 0.21 percent in 2022.

Ceftriaxone is currently the frontline treatment for gonorrhea as the bacterium has developed resistance to other antibiotics over the years. In the past, penicillin and tetracycline were the drugs of choice, but their effectiveness declined due to bacterial resistance. Then, fluoroquinolones, including Cipro, were used, but resistance to them also emerged. Following that, cephalosporins, such as cefixime, became the recommended treatment until resistance to cefixime developed in 2012. In 2020, azithromycin was abandoned, leaving ceftriaxone as the last line of defense against the infection in the US.

The rapid spread of ceftriaxone-resistant isolates in China is particularly alarming. The study examined 2,804 isolates from 13 of the country's 19 provinces, representing 2.9 percent of all reported gonorrhea cases in 2022. Among these isolates, the overall prevalence of ceftriaxone-resistant strains was 8.1 percent. Shockingly, five provinces recorded rates above 10 percent, with three provinces reporting rates above 25 percent. Furthermore, 18 isolates were found to be resistant to all tested antibiotics, except for the discontinued spectinomycin.

While the study does have limitations, including underreporting of cases and a limited sample size, the findings highlight the urgent need for a comprehensive approach to tackle antibiotic-resistant Neisseria gonorrhoeae in China. The authors of the study emphasized the importance of identifying factors contributing to high resistance rates, especially in provinces where the percentage of ceftriaxone-resistant isolates exceeds 10 percent. They also emphasized the global significance of this issue, as these resistant strains have already spread internationally. The researchers called for collaborative efforts and cross-border monitoring to mitigate the further spread of drug-resistant gonorrhea.

With drug-resistant gonorrhea on the rise in China and other parts of the world, experts are increasingly concerned about the potential for untreatable cases. Public health officials are urging for intensified efforts in surveillance, prevention, and development of new treatment strategies to combat this pressing public health concern.
