Between December 2021 and June 2022, 10 cases of ceftriaxone-resistant Neisseria gonorrhoeae (ST8123; n = 8) were detected in the United Kingdom, compared with nine cases during the previous 6 years. Most of these cases were associated with travel from the Asia-Pacific region; all were heterosexual people, with most in their 20s. Although all cases were successfully treated, not all partners of cases could be traced, and there is a risk of further transmission of ceftriaxone-resistant gonococcal infection within the UK.
Purpose of review
As the evidence for two-drug regimens (2DR) for HIV treatment accumulates and 2DR start to enter consensus guidelines, this review covers the history, rationale and current evidence for 2DR in first-line and switch settings.
Recent findings
Until recently, most evidence for 2DR was for boosted protease inhibitor-based therapies but now we have large, randomized trials to support the use of dolutegravir (DTG)-based 2DR, both for initial therapy and suppressed switch, with high efficacy and no emergent resistance at failure.
Summary
2DR will increasingly form part of the choice we are able to offer people with HIV but we must consider some of the limitations to ensure these regimens are used in the most clinically appropriate manner.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
