Hepatitis E virus (HEV) infection is an emerging infection in developed countries and is thought to be a porcine zoonosis. HEV can cause chronic infection and cirrhosis in the immunosuppressed, including patients with HIV infection. Little is known about HEV and HIV coinfection. The aim of the study was to document the incidence of chronic HEV coinfection in patients with HIV infection and to determine the anti-HEV seroprevalence and compare it with that of a control population. MethodsA cohort/case-control study was carried out in two teaching hospitals in southwest England. A total of 138 patients with HIV infection were tested for HEV using an immunoassay for anti-HEV immunoglobulin M (IgM) and IgG and reverse transcriptase-polymerase chain reaction (RT-PCR), and 464 control subjects were tested for anti-HEV IgG. Demographic, lifestyle and laboratory data were prospectively collected on each patient with HIV infection. The anti-HEV IgG seroprevalence in patients with HIV infection was compared with that in controls and demographic risk factors for HEV exposure were explored using logistic regression models. ResultsThere was no difference in anti-HEV IgG seroprevalence between the HIV-infected patients and controls. The only risk factor predictive of anti-HEV seropositivity was the consumption of raw/ undercooked pork; sexual risk factors were unrelated. No patient with HIV infection had evidence of chronic coinfection with HEV Conclusions Anti-HEV seroprevalence is similar in controls and patients with HIV infection. Risk factor analysis suggests that HEV is unlikely to be transmitted sexually. Chronic coinfection with HEV was absent, indicating that chronic HEV/HIV coinfection is not a common problem in this cohort.
The UK National Guidelines on HIV testing (2008) recommend routinely offering an HIV test to patients in certain clinical settings. We wished to investigate the acceptability of implementing these guidelines in a population with a low HIV prevalence. Patients accessing primary and secondary care were asked to circle one of the five responses to a series of statements regarding HIV testing. Of the 616 respondents, 579 (94%) stated they would be willing to be tested if presenting with a condition known to be associated with HIV. Four hundred and forty out of 616 (71%) stated they would be willing to be tested as part of their routine care, while 445/616 (72%) stated they would be willing to have the result in their main medical notes. Although the patients' responses were largely receptive to increased testing, we encountered notable negative attitudes to the project from professional and administrative staff. Resistance to increased HIV testing may be related to health-care workers rather than patients.
Background Pre-exposure prophylaxis (PrEP) was introduced in Sexual Health Services of the Welsh National Health Service (NHS Wales) in July 2017 as a 3-year pilot service. Methods: Data were collected through the pre-existing Sexual Health in Wales Surveillance System, to which codes were added to capture PrEP eligibility, outcome of offer of PrEP, reasons for declining and adherence. Eligibility categories were defined based on nationally agreed criteria: men who have sex with men (MSM) and transgender people at high risk of HIV acquisition; partners of HIV-positive individuals not known to be virally suppressed; and heterosexuals reporting condomless intercourse with a HIV-positive individual not known to be virally suppressed. Results: During the first 6 months, 516 people were eligible, 96% of which were MSM. Overall, 57% of those eligible (296/516) started PrEP. Reasons for declining PrEP were given by 88 (56%) of 157 people; 50 (57%) of whom did not believe themselves to be at risk. Of the available adherence assessments, 89% considered that all risk episodes had been covered. Persistence at 3 months was assessed for 141 people, of which 93 (66%) were still using PrEP. There were no HIV diagnoses in people taking PrEP during the first 6 months. Twenty-nine people were diagnosed with 37 episodes of sexually transmissible infections (STIs) while on PrEP. STI incidence was 105.7 per 100 person-years. Conclusions: The early trend indicates that implementation of PrEP is progressing as planned, and the service has been utilised by clients. This analysis can help refine implementation, inform planning and research around uptake, use and effect in Wales and internationally.
We examined PrEP use, condomless anal sex (CAS), and PrEP adherence among men who have sex with men (MSM) attending sexual health clinics in Wales, UK. In addition, we explored the association between the introduction of measures to control transmission of SARS-CoV-2 on these outcomes. We conducted an ecological momentary assessment study of individuals in receipt of PrEP in Wales. Participants used an electronic medication cap to record PrEP use and completed weekly sexual behaviour surveys. We defined adherence to daily PrEP as the percentage of CAS episodes covered by daily PrEP (preceded by ≥ 3 days of PrEP and followed by ≥ 2 days). Sixty participants were recruited between September 2019 and January 2020. PrEP use data prior to the introduction of control measures were available over 5785 person-days (88%) and following their introduction 7537 person-days (80%). Data on CAS episodes were available for 5559 (85%) and 7354 (78%) person-days prior to and following control measures respectively. Prior to the introduction of control measures, PrEP was taken on 3791/5785 (66%) days, there were CAS episodes on 506/5559 (9%) days, and 207/406 (51%) of CAS episodes were covered by an adequate amount of daily PrEP. The introduction of pandemic-related control measures was associated with a reduction in PrEP use (OR 0.44, 95%CI 0.20–0.95), CAS (OR 0.35, 95%CI 0.17–0.69), and PrEP adherence (RR = 0.55, 95%CI 0.34–0.89) and this may have implications for the health and wellbeing of PrEP users and, in addition to disruption across sexual health services, may contribute to wider threats across the HIV prevention cascade.
Trichomonas vaginalis is a sexually transmitted protozoan infection resulting in vulvo-vaginitis and altered vaginal discharge in symptomatic women. Trichomoniasis has been implicated in causing adverse pregnancy outcomes such as low birth weight and pre-term labour. Metronidazole is the recommended first-line treatment for trichomonal infection. Other nitroimidazoles, such as tinidazole, are used as alternative regimens with similar activity but at a greater expense. Treatment failure usually represents patient non-compliance or re-infection, although metronidazole resistance has previously been documented. Antimicrobial susceptibility testing for T. vaginalis is currently not available in the UK. Patients with disease unresponsive to first-line treatments pose a major challenge, as therapeutic options are limited. We present the case of a patient with presumed resistant infection during pregnancy, and the additional treatment issues that this presented.
Background This service is located in a large district general hospital bordering a large UK city. It was noticed over a short period that there were several discrepant results returned for detection of Neisseria gonorrhoeae (GC) using PCR technologies and traditional culture. Aim We performed a 3-month look back at all samples sent for GC detection, in order to define local incidence of GC and discrepant results. Methods All samples sent over the preceding 3 months from this service, either as local testing or as part of the national programme, were identified using computer records and then recorded into an excel spreadsheet for comparisons (see abstract P42 table 1). Results 1245 cases were identified during the 3-month period. The total number of cases with at least one positive GC result from culture and PCR was 41 (3.29% of tested). 902 patients (72.5% of those tested) had samples sent for culture. Culture was on vancomycin-colistin-nystatin-trimethoprim enriched agar. 24 (2.7%) were reported positive for GC. There was a total of 1225 PCR based tests collected between the local and national programmes (98.4% of all cases). Abstract P42 Table 1 shows the specific methods of these two programmes. Of the 1225, 39 tests were positive (3%). All cases with a positive result were then further analysed. 27 had concordant results, that is, either the culture and PCR matched, or only one of the two tests was performed. This gave 14 patients with discordant results (1.1% of all tested, 34% of all positive results). 13 cases had a positive PCR but negative culture (93%), and one patient had a positive culture but negative PCR.
