RESUMO

BACKGROUND: Between May and November, 2022, global outbreaks of human monkeypox virus infection have been reported in more than 78 000 people worldwide, predominantly in men who have sex with men. We describe the epidemiological and clinical characteristics of monkeypox virus infection in cisgender (cis) and transgender (trans) women and non-binary individuals assigned female sex at birth to improve identification and understanding of risk factors. METHODS: International collaborators in geographical locations with high numbers of diagnoses of monkeypox virus infection were approached and invited to contribute data on women and non-binary individuals with confirmed monkeypox virus infection. Contributing centres completed deidentified structured case-report spreadsheets, adapted and developed by participating clinicians, to include variables of interest relevant to women and non-binary individuals assigned female at birth. We describe the epidemiology and clinical course observed in the reported infections. FINDINGS: Collaborators reported data for a total of 136 individuals with monkeypox virus infection who presented between May 11 and Oct 4, 2022, across 15 countries. Overall median age was 34 years (IQR 28-40; range 19-84). The cohort comprised 62 trans women, 69 cis women, and five non-binary individuals (who were, because of small numbers, grouped with cis women to form a category of people assigned female at birth for the purpose of comparison). 121 (89%) of 136 individuals reported sex with men. 37 (27%) of all individuals were living with HIV, with a higher proportion among trans women (31 [50%] of 62) than among cis women and non-binary individuals (six [8%] of 74). Sexual transmission was suspected in 55 (89%) trans women (with the remainder having an unknown route of transmission) and 45 (61%) cis women and non-binary individuals; non-sexual routes of transmission (including household and occupational exposures) were reported only in cis women and non-binary individuals. 25 (34%) of 74 cis women and non-binary individuals submitted to the case series were initially misdiagnosed. Overall, among individuals with available data, rash was described in 124 (93%) of 134 individuals and described as anogenital in 95 (74%) of 129 and as vesiculopustular in 105 (87%) of 121. Median number of lesions was ten (IQR 5-24; range 1-200). Mucosal lesions involving the vagina, anus, or oropharynx or eye occurred in 65 (55%) of 119 individuals with available data. Vaginal and anal sex were associated with lesions at those sites. Monkeypox virus DNA was detected by PCR from vaginal swab samples in all 14 samples tested. 17 (13%) individuals were hospitalised, predominantly for bacterial superinfection of lesions and pain management. 33 (24%) individuals were treated with tecovirimat and six (4%) received post-exposure vaccinations. No deaths were reported. INTERPRETATION: The clinical features of monkeypox in women and non-binary individuals were similar to those described in men, including the presence of anal and genital lesions with prominent mucosal involvement. Anatomically, anogenital lesions were reflective of sexual practices: vulvovaginal lesions predominated in cis women and non-binary individuals and anorectal features predominated in trans women. The prevalence of HIV co-infection in the cohort was high. FUNDING: None.

RESUMO

BACKGROUND: Mass gatherings and large sporting events, such as the Olympics, may potentially pose a risk of increased sexually transmitted infection (STI) transmission and increase burden on local STI services. The objectives of this analysis were to assess whether the STI profile of Olympic visitors differed from that of the local STI clinic population and to investigate what impact these visitors had on local STI services. METHODS: Self-administered questionnaires (completed by 29,292 patients) were used to determine the visitor status of patients attending 20 STI clinics, between July 20, 2012, and September 16, 2012, in the host cities, London and Weymouth. Using routine surveillance data from the Genitourinary Medicine Clinic Activity Dataset version 2, Olympic visitors were compared with usual attendees (local residents and non-Olympic visitors) in terms of their demographic characteristics, services utilized, and STIs diagnosed using univariate and multivariate methods. RESULTS: Compared with usual attendees, Olympic visitors were more likely to be heterosexual males (56.0% vs. 34.9%, P = 0.001), aged between 15 and 24 years of age (47.1% vs. 34.0%, P = 0.001), of white ethnicity (81.9% vs. 66.4%, P = 0.001), and born in Australasia, Asia, North America, or South America (18.8% vs. 12.0%, P = 0.006). Olympic visitors constituted 1% of new clinic attendances and were less likely to be diagnosed as having a new STI (adjusted odds ratio, 0.69; 95% confidence interval, 0.48-0.98; P = 0.040). CONCLUSIONS: In this first multisite study to examine the effect of Olympic visitors on local sexual health services, the 2012 Olympic Games was found to have minimal impact. This suggests that a "business as usual" approach would have been sufficient.

RESUMO

OBJECTIVE: To determine whether the 2012 Olympic and Paralympic Games were associated with a change in the number of patients attending or diagnosed with a new sexually transmitted infection (STI) at sexual health clinics in London and Weymouth. METHODS: We undertook an interrupted time-series analysis of surveillance data from the Genitourinary Medicine Clinic Activity Dataset (GUMCAD) collected at 33 genitourinary medicine (GUM) clinics in London and Weymouth (where Games events were concentrated) between 2009 and 2012. Mixed-effects linear regression models of weekly attendance and diagnoses, incorporating temporal trends, bank holidays, categorical month and clinic closures, were used to test for the effect of the 'Olympic-Paralympic' period. We subdivided the 9-week 'Olympic-Paralympic' period (16 July 2012 to 17 September 2012) into five periods, including three Olympic weeks, two Paralympic weeks, pre-, post- and inter-Games weeks. We also compared characteristics of patients attending during the Olympic-Paralympic period and those attending during the same period in 2011. RESULTS: During the 3 weeks of the Olympics, there was a significant reduction in the number of new episode attendances (2020 fewer, 5.6% reduction (95% CI -8.2 to -2.9)) and the number of patients diagnosed with an STI (267 fewer, 4.8% reduction (95% CI -8.6 to -0.9)) compared to expected. There were no important differences in the profile of patients attending during the 2012 Olympic-Paralympic period and those attending during the same period in 2011. CONCLUSIONS: We conclude that a 'business-as-usual' approach to managing local sexual health clinics during the 2012 Olympic and Paralympics would have been appropriate.

RESUMO

BACKGROUND: HIV and tuberculosis (TB) are commonly associated. Identifying latent and asymptomatic tuberculosis infection in HIV-positive patients is important in preventing death and morbidity associated with active TB. METHODS: Cross-sectional study of one time use of an interferon-gamma release assay (T-SPOT.TB - immunospot) to detect tuberculosis infection in patients in a UK inner city HIV clinic with a large sub-Saharan population. RESULTS: 542 patient samples from 520 patients who disclosed their symptoms of TB were tested. Median follow-up was 35 months (range 27-69). More than half (55%) originated from countries with medium or high tuberculosis burden and 57% were women. Antiretroviral therapy was used by 67%; median CD4 count at test was 458 cells/µl. A negative test was found in 452 samples and an indeterminate results in 40 (7.4%) but neither were associated with a low CD4 count. A positive test was found in 10% (50/502) individuals. All patients with positive tests were referred to the TB specialist, 47 (94%) had a chest radiograph and 46 (92%) attended the TB clinic. Two had culture-positive TB and a third individual with features of active TB was treated. 40 started and 38 completed preventive treatment. One patient who completed preventive treatment with isoniazid monotherapy subsequently developed isoniazid-resistant pulmonary tuberculosis. No patient with a negative test has developed TB. CONCLUSIONS: We found an overall prevalence of latent TB infection of 10% through screening for TB in those with HIV infection and without symptoms, and a further 1% with active disease, a yield greater than typically found in contact tracing. Acceptability of preventive treatment was high with 85% of those with latent TB infection eventually completing their TB chemotherapy regimens. IGRA-based TB screening among HIV-infected individuals was feasible in the clinical setting and assisted with appropriate management (including preventive treatment and therapy for active disease). Follow-up of TB incidence in this group is needed to assess the long-term effects of preventive treatment.

RESUMO

INTRODUCTION: Erectile dysfunction is common in HIV-positive men who have sex with men (MSM). A standardized scale is needed to assess erectile function in clinical practice and research studies. AIM: The International Index of Erectile Function (IIEF) is a widely accepted tool for assessing erectile function designed for heterosexual men. We modified the tool for MSM. We present an analysis of internal consistency of the questionnaire in an HIV-positive cohort. METHODS: The adapted questionnaire included modified questions within each of the five domains of the IIEF: (i) erectile function, (ii) intercourse satisfaction, (iii) orgasmic function, (iv) sexual desire, and (v) overall satisfaction with sex. MSM at seven European HIV treatment centers completed the questionnaire. MAIN OUTCOME MEASURES: Responses were analyzed for internal consistency using standardized Cronbach's alpha values within each of the five domains. A factor analysis was performed to confirm the domain structure of the questionnaire. RESULTS: Data from 486 MSM were analyzed. The factor analysis supported the domain structure described. Questions about erectile function, orgasmic function, and sexual desire performed well, with Cronbach's alpha values of 0.82, 0.83, and 0.89, respectively. Questions concerning intercourse satisfaction were less consistent (Cronbach's alpha 0.55) because frequency of attempts at sexual intercourse did not correlate with other responses. Responses about satisfaction with sex with a regular partner diverged from satisfaction with overall sex life. Frequency of morning erections diverged from other aspects of erectile function, whereas erections with masturbation correlated better. CONCLUSIONS: Internal consistency was high overall. This tool is suitable for HIV-positive MSM and can be used in screening, research, and monitoring treatment response.

RESUMO

BACKGROUND: Fetal alcohol syndrome (FAS) has been identified as a major cause of impairment to normal physical and intellectual development among Indigenous children in Far North Queensland; however, little is known of the pregnancy characteristics of mothers of those children diagnosed with FAS or of interventions that might assist in lowering the prevalence of the syndrome. AIM: To review the pregnancy records of women whose infants were subsequently diagnosed with FAS by the Paediatric Outreach Service (POS) of the Cairns Base Hospital, and to determine how such women might be identified prospectively in pregnancy and offered intervention to reduce alcohol consumption. METHODS: A retrospective case-control study involving all children diagnosed with FAS by the POS between 1994 and 2006; maternal pregnancy records were accessed and details obtained. RESULTS: Mothers of cases were older, of higher parity, smoked more cigarettes, attended fewer antenatal visits and experienced more antenatal and delivery complications than mothers of controls. The average gestational age at booking was not statistically significant between the two groups. There was a significant difference between the two groups in self-reported alcohol consumption both before and during pregnancy and in numbers of women who decreased alcohol consumption once the diagnosis of pregnancy was known to them. CONCLUSIONS: There is the potential to identify prospectively women presenting for antenatal care who are heavy drinkers and risk FAS in their infants, using the self-reported information about alcohol intake already being collected by our service; such women may then be offered specific interventions to try to reduce alcohol consumption in pregnancy.

RESUMO

Current methods of contact tracing are only partially effective. Patient-delivered partner medication (PDPM), in which patients are dispensed antibiotics for their sexual partner(s), has been shown to reduce persistent and recurrent infections. We performed a questionnaire to canvass opinions of UK staff and patients about PDPM. The response rate was 72% (88/122) for staff and 90% (473/525) for patients. The majority of staff (81%) thought that PDPM would be acceptable to patients, and should be combined with written information and a recommendation to attend a clinic. Patients were mostly (59%) in favour of PDPM, 87% thought it would make it easier to abstain from sex during treatment, and 94% indicated that after being given antibiotics by a partner, they would attend a clinic for tests. Concerns expressed by staff and patients included drug allergies, potential lack of information provided to partners, management of complicated infection, pregnancy and medicolegal implications.

RESUMO

A man developed HIV-1 antibodies, which disappeared spontaneously. He had negative HIV viral load and p24 antigen tests and did not develop immunosuppression. Further investigations suggest the HIV-positive result was a nonspecific reaction. An alternative explanation is that he was exposed to HIV and had a "near-miss" HIV infection.

RESUMO

Transplantation of HLA-identical or haploidentical T cell-depleted allogeneic bone marrow (BM) into SCID infants results in thymus-dependent T cell development in the recipients. Immunoscope analysis of the TCR V beta repertoire was performed on 15 SCID patients given BM transplants. Before and within the first 100 days after bone marrow transplantation (BMT), patients' PBMC displayed an oligoclonal or skewed T cell repertoire, low TCR excision circles (TREC) values, and a predominance of CD45RO(+) T cells. In contrast, the presence of high numbers of CD45RA(+) cells in the circulation of SCID patients >100 days post-BMT correlated with active T cell output by the thymus as revealed by high TREC values and a polyclonal T cell repertoire demonstrated by a Gaussian distribution of V beta-specific peaks. Ten years after BMT, we observed a decrease of the normal polyclonal T cell repertoire and an increase of a more skewed T cell repertoire. A decline of TREC levels and a decrease in the number of CD45RA(+) cells beyond 10 years after BMT was concomitant with the detection of oligoclonal CD3(+)CD8(+)CD45RO(+) cells. The switch from a polyclonal to a more skewed repertoire, observed in the CD3(+)CD8(+)CD45RO(+) T cell subset, is a phenomenon that occurs normally with decreased thymic output during aging, but not as rapidly as in this patient population. We conclude that a normal T cell repertoire develops in SCID patients as a result of thymic output and the repertoire remains highly diverse for the first 10 years after BMT. The TCR diversity positively correlates in these patients with TREC levels.
