Multi-Drug Resistant Gonorrhea: An Emerging Global Threat

Abstract

<i>Neisseria gonorrhoeae</i> is the bacterial culprit behind gonorrhea, a highly prevalent sexually transmitted infection (STI) found worldwide. Despite over 1 million daily cases, many infections are asymptomatic, contributing to its widespread transmission. The emergence of multidrug-resistant strains poses a significant challenge to public health, limiting treatment options and increasing the risk of complications. Key aspects covered include the bacterium's transmission dynamics, pathogenesis, clinical manifestations, laboratory diagnosis methods, and epidemiology. Transmission primarily occurs through sexual contact, with the bacterium thriving on mucous membranes in various parts of the body. Clinical presentations range from urethritis and cervicitis to more severe complications such as pelvic inflammatory disease and disseminated gonococcal infection. Laboratory diagnosis relies on culture, nucleic acid amplification tests (NAATs), and Gram staining, with NAATs offering high sensitivity. However, antimicrobial susceptibility testing is essential to guide treatment decisions, given the rapid emergence of resistance. Gonorrhea's epidemiology varies globally, with higher prevalence rates in low- and middle-income countries. Surveillance programs play a crucial role in monitoring antimicrobial resistance trends and informing treatment guidelines. The economic burden of gonorrhea is substantial, with potential increases in medical expenses and the challenge of managing outbreaks. Despite these challenges, there is hope for the development of new treatments and vaccines. Promising candidates such as zoliflodacin and solithromycin have shown efficacy in clinical trials, while vaccine development faces obstacles due to the bacterium's antigenic variation. The paper provides a comprehensive overview of <i>N. gonorrhoeae,</i> covering its basic features, transmission, pathogenesis, clinical presentation, laboratory diagnosis, epidemiology, challenges of drug-resistant gonorrhea, and prospects for the development of new treatments and vaccines. The paper underscores the urgent need for continued research, surveillance, and development of effective strategies to combat drug-resistant gonorrhea. Investment in new treatments and vaccines is crucial to mitigate the spread of the infection and its associated complications.
