Fighting the Silent Epidemic: New WHO Guidelines Aim to Slash Global STI Rates

The WHO's new guidelines on STI treatment and management aim to tackle the rising global burden of these infections through updated treatment protocols and innovative testing strategies. Key recommendations include increased dosages for treating gonorrhoea, the introduction of dual RDTs and self-testing for syphilis, and comprehensive partner services to reduce reinfection and transmission.

In a bold new move to tackle the growing threat of sexually transmitted infections (STIs), the World Health Organization (WHO) has released updated recommendations aimed at reducing the global burden of these diseases. The new guidelines, published in "Updated Recommendations for the Treatment of Neisseria gonorrhoeae, Chlamydia trachomatis, and Treponema pallidum (syphilis), and New Recommendations on Syphilis Testing and Partner Services," seek to curb the rise in STI cases through targeted treatment and innovative testing strategies.

A Global Health Crisis

The statistics are alarming: in 2020 alone, there were an estimated 374 million new cases of curable STIs worldwide. These include 156.3 million cases of trichomoniasis, 128.5 million cases of chlamydia, 82.4 million cases of gonorrhoea, and 7.1 million cases of syphilis. The WHO has set ambitious goals to reduce gonorrhoea and syphilis infections by 90% by 2030 and to eliminate congenital syphilis as a public health issue.

The Challenge of Resistance

One of the significant hurdles in STI treatment is the rapidly changing patterns of antimicrobial resistance, particularly for Neisseria gonorrhoeae. This pathogen has developed resistance to almost every available antibiotic, leaving ceftriaxone as the last line of defense in many countries. However, resistance to ceftriaxone has also been reported, underscoring the urgent need for updated treatment protocols.

The WHO's new guidelines recommend increased dosages for certain treatments to delay the development of resistance. For gonococcal infections, options include ceftriaxone 1 g intramuscularly as a single dose or cefixime 800 mg orally plus azithromycin 2 g orally, among others. These recommendations are designed to provide healthcare providers with effective tools to combat these infections while minimizing the risk of further resistance.

Innovative Testing and Treatment Approaches

In addition to updated treatment protocols, the WHO has introduced new recommendations for syphilis testing and partner services. Dual treponemal/non-treponemal rapid diagnostic tests (RDTs) are now recommended as an additional approach within syphilis testing strategies. This innovative testing method allows for quicker, more accurate diagnosis, which is crucial for timely treatment.

Syphilis self-testing is also suggested as an additional approach, empowering individuals to take control of their health. This method can be particularly beneficial in areas with limited access to healthcare facilities, providing a discreet and convenient option for STI testing.

For the treatment of chlamydial infections, the guidelines highlight the efficacy of doxycycline (100 mg orally twice a day for seven days) and suggest azithromycin 1 g orally as a single dose for those who cannot adhere to a multi-dose regimen. Pregnant women with syphilis are advised to use benzathine penicillin, with alternatives such as procaine penicillin or ceftriaxone available when necessary.

Comprehensive Partner Services

A critical component of the new guidelines is the emphasis on STI partner services. The WHO recommends offering a range of voluntary services to individuals with STIs, including patient referral, enhanced patient referral, expedited partner therapy (EPT), and provider-assisted referral. These services aim to reduce reinfection rates and prevent further transmission, playing a vital role in comprehensive STI management.

Implementation of these guidelines requires careful integration into existing health services, considering local epidemiology, resource availability, health system capacity, and cost-effectiveness. It's also crucial to promote and protect the human rights of people receiving STI services, ensuring that the use of these services is always voluntary and free from stigma and discrimination.

A Path Forward

The WHO's updated recommendations are designed to support countries in achieving their global STI reduction targets. By providing clear and actionable guidelines for the treatment and management of key STIs, the WHO aims to significantly impact public health outcomes worldwide.
