Detection of 10 cases of ceftriaxone-resistant Neisseria gonorrhoeae in the United Kingdom, December 2021 to June 2022.

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.

Spontaneous clearance of genital and extragenital Neisseria gonorrhoeae: data from GToG.

OBJECTIVES: Neisseria gonorrhoeae (NG) infection can resolve without antibiotic treatment, however the literature describing the frequency of clearance at individual sites, how rapidly it occurs and potential predictive factors is limited. In this analysis of a subpopulation identified from a large multicentre UK cohort, we describe the overall rate of spontaneous clearance of infection and explore factors associated with this. METHODS: Data from the Gentamicin compared with Ceftriaxone for the Treatment of Gonorrhoea randomised controlled trial consisting of 720 patients with NG were analysed. A subgroup of individuals had both a pretrial test sample and a trial enrolment sample taken. Those who had cleared NG between initial presentation and subsequent entry into the trial without antibiotic treatment were deemed to have spontaneously cleared. Sociodemographic characteristics, sexual history and sites of infection for those who spontaneously cleared infection were compared with that of those who did not. We also estimated the time interval to clearance. RESULTS: Overall, the proportion who had spontaneous clearance was 20.5% (83/405). Clearance of infection occurred over a median of 10 days (IQR 7-15 days). The cohort who spontaneously cleared were similar to those who did not in terms of age, gender, sexual orientation, HIV status and previous NG infection. Chlamydia coinfection was more frequent in the 'no spontaneous clearance group' (11.1% (9/83) cf 22.0% (69/322)) (p=0.029). Dysuria was reported more often in the 'no spontaneous clearance group' (4.8% (4/83) cf 13.0% (42/322)) (p=0.035). CONCLUSION: We present data from a large cohort of NG-infected individuals, of whom a significant proportion had spontaneous clearance of infection. This is consistent with previous smaller studies. If this is indicative of cure, point-of-care testing prior to treatment has the potential to reduce unnecessary exposure to antimicrobials. Further work to assess the importance of bacterial load, genotype and host immune response on spontaneous clearance of infection is required. TRIAL REGISTRATION NUMBER: ISRCTN51783227.

Should we still use azithromycin for gonorrhoea treatment?

This review presents the evidence for azithromycin in the treatment of gonorrhoea, both as monotherapy and as a component of dual therapy. Uncertainties are explored regarding the efficacy of a dual treatment strategy, combining ceftriaxone and azithromycin, in the context of resistance trends and extra-genital infections. The association between microbiological testing and clinical outcome for the individual patient, and the effect of azithromycin use on other sexually transmissible infections, are considered. Finally, in the absence of imminent new antimicrobials, optimising the dose of azithromycin while maintaining tolerability is discussed.

Auditing the use and assessing the clinical utility of microscopy as a point-of-care test for Neisseria gonorrhoeae in a Sexual Health clinic.

We assessed whether urethral microscopy was performed as per clinic protocol for male clinic attendees reporting contact with Neisseria gonorrhoeae (GC), urethral symptoms or given a diagnosis of epididymo-orchitis (EO) over a 12-month period (9732 patients). Prevalence of gonorrhoea in the contacts, urethral symptoms and EO groups was 50, 12.7 and 1.6%, respectively. Microscopy was performed reliably for contacts (96%), those with discharge/dysuria with evidence of urethritis on examination (98%), but not those with EO (43%). We explored the clinical utility of microscopy as a point-of-care test for identifying urethral GC in each subgroup, using the APTIMA Combo 2 CT/GC nucleic acid amplification test as the comparator (1710 patients). Sensitivity of microscopy for each subgroup was good; there was no statistical difference between subgroup sensitivity using Fisher's exact test. Microscopy is valuable to ensure prompt diagnosis and contact tracing. All GC contacts were treated 'epidemiologically'; however, half of GC contacts did not have GC. Microscopy identified the majority of GC cases, including amongst contacts (71% of heterosexual contacts, 66% of contacts reporting sex with men). We propose that epidemiological treatment for GC contacts should be reconsidered on the grounds of antibiotic stewardship, favouring use of microscopy to guide treatment decisions.

Late diagnosis among our ageing HIV population: a cohort study.

INTRODUCTION: With the advent of combined antiretroviral therapy (cART), more people infected with HIV are living into older age; 22% of adults receiving care in the UK are aged over 50 years [1]. Age influences HIV infection; the likelihood of seroconversion illness, mean CD4 count and time from infection to development of AIDs defining illnesses decreases with increasing age. A UK study estimates that half of HIV infections in persons over 50 years are acquired at an age over 50 [2]. Studies exploring sexual practices in older persons have repeatedly shown that we cannot assume there is no risk of STI and HIV infection [3,4]. Physicians should be alert to risk of HIV even in the older cohort, where nearly half diagnoses are made late [2]. Local audit has demonstrated poor testing rates in the over 50's on the Acute Medical Unit. Late diagnosis (CD4<350) results in poorer outcomes and age confounds further; older late presenters are 2.4 times more likely to die within the first year of diagnosis than younger counterparts [2]. MATERIALS AND METHODS: A retrospective case notes review was conducted of all patients aged 60 years and over attending HIV clinic in the last 2 years. Outcomes audited included features around diagnosis; age, presentation, missed testing opportunities and CD4 count at diagnosis. RESULTS: Of the current cohort of 442 patients, 34 were over 60 years old (8%). Age at diagnosis in this group ranged from 36 to 80 years, mean 56.6 years. Presentation triggers included opportunistic infections or malignancies (n=10), constitutional symptoms (n=6), diagnosis of another STI (n=4), seroconversion illness (n=2), partner status (n=3). Eight patients were diagnosed through asymptomatic screening at Sexual Health. We identified missed opportunities in five patients who were not tested despite diagnoses or symptoms defined as clinical indicators for HIV. Half of older patients had a CD4 count of <200 at diagnosis. CONCLUSIONS: It is imperative that general medical physicians and geriatricians are alert to enquiring about risk and testing for HIV where clinical indicators are present, irrespective of age. The oldest patient in the cohort was diagnosed with HIV aged 80 years. All patients with missed opportunities for testing were over 47 years old.
