RESUMO

OBJECTIVES: We examined follicle-stimulating hormone (FSH) levels in women living with HIV aged > 45 reporting ≥ 12 months' amenorrhoea, and investigated correlation with menopausal symptoms. METHODS: A cross-sectional substudy of 85 women from the Positive Transitions through the Menopause (PRIME) Study who reported irregular periods at entry into the PRIME Study and ≥ 12 months' amenorrhoea at recruitment into this substudy. Serum FSH was supplemented with clinical data and menopausal symptom assessment. Serum FSH > 30 mIU/mL was defined as consistent with postmenopausal status. Associations between FSH and menopausal symptom severity were assessed using Pearson's correlation and the Kruskal-Wallis test. RESULTS: Median age was 53 years [interquartile range (IQR): 51-55]; all were on antiretroviral therapy, three-quarters (n = 65) had a CD4 T-cell count > 500 cells/µL and 91.8% (n = 78) had an HIV viral load (VL) < 50 copies/mL. Median FSH was 65.9 mIU/mL (IQR: 49.1-78.6). Only four women (4.7%) had FSH ≤ 30 mIU/mL; none reported smoking or drug use, all had CD4 T-cell count ≥ 200 cells/µL, and one had viral load (VL) ≥ 50 copies/mL. Median body mass index (BMI) was elevated compared with women with FSH > 30 mIU/mL (40.8 vs. 30.5 kg/m2 ). Over a quarter (28.2%) reported severe menopausal symptoms, with no correlation between FSH and severity of menopausal symptoms (p = 0.21), or hot flushes (p = 0.37). CONCLUSIONS: Four women in this small substudy had low FSH despite being amenorrhoeic; all had BMI ≥ 35 kg/m2 . We found that 95% of women with HIV aged > 45 years reporting ≥ 12 months' amenorrhoea had elevated FSH, suggesting that menopausal status can be ascertained from menstrual history alone in this group.

RESUMO

Background Following an upward trajectory in Lymphogranuloma venereum (LGV) diagnoses in the UK from 2004 to 2016, with annual diagnoses increasing from 28 to 904, diagnoses fell to 641 in 2017; this was inconsistent with the upward trend in other bacterial sexually transmissible infections (STIs) between 2016 and 2017. An analysis of surveillance data from multiple sources to investigate the possible factors contributing to this decline in LGV was performed. METHODS: LGV tests and diagnoses in the UK from 2004 to 2018 were captured through laboratory data from the LGV Reference Laboratories and laboratories conducting in-house LGV testing. These data and clinical diagnoses data from England were analysed alongside the national management guidelines issued over the course of the epidemic. RESULTS: LGV diagnoses increased between 2004 and 2015 and then decreased between 2016 and 2018. LGV testing increased from 2010 to 2018 (2690-10850). Test positivity halved between 2015 (14.8%, 929-6272) and 2018 (7.3%, 791-10850). Peaks in LGV testing and diagnoses appeared to coincide with the publication of national LGV management guidelines and changes to clinical practice. The proportion of LGV diagnoses among HIV-positive men who have sex with men (MSM) fell between 2013 and 2018 (74-48%). CONCLUSIONS: The fall in diagnoses and positivity were likely due to increasing earlier clinical diagnosis and treatment. Changes to the national management guidelines, the clinical policy and practice of some larger clinics and potentially changes to the guidelines for the treatment of chlamydia broadened the scope of testing and increased testing in asymptomatic patients which, in combination, likely had a positive effect on the control of LGV infection.

RESUMO

BACKGROUND: It is cost-effective to perform an HIV test in people with specific indicator conditions (IC) with an undiagnosed HIV prevalence of at least 0.1%. Our aim was to determine the HIV prevalence for 14 different conditions across 20 European countries. METHODS: Individuals aged 18-65 years presenting for care with one of 14 ICs between January 2012 and June 2014 were included and routinely offered an HIV test. Logistic regression assessed factors associated with testing HIV positive. Patients presenting with infectious mononucleosis-like syndrome (IMS) were recruited up until September 2015. RESULTS: Of 10,877 patients presenting with an IC and included in the analysis, 303 tested positive (2.8%; 95% CI 2.5-3.1%). People presenting with an IC in Southern and Eastern Europe were more likely to test HIV positive as were people presenting with IMS, lymphadenopathy and leukocytopenia/ thrombocytopenia. One third of people diagnosed with HIV after presenting with IMS reported a negative HIV test in the preceding 12 months. Of patients newly diagnosed with HIV where data was available, 92.6% were promptly linked to care; of these 10.4% were reported lost to follow up or dead 12 months after diagnosis. CONCLUSION: The study showed that 10 conditions had HIV prevalences > 0.1%. These 10 ICs should be adopted into HIV testing and IC specialty guidelines. As IMS presentation can mimic acute HIV sero-conversion and has the highest positivity rate, this IC in particular affords opportunities for earlier diagnosis and public health benefit.

RESUMO

BACKGROUND: Late HIV diagnosis remains one of the challenges in combating the epidemic. Primary care providers play an important role in screening for HIV infection. Our study aims to evaluate the relationship between knowledge and barriers to HIV testing and screening outcomes. The impact of an education program for primary care providers, towards improving HIV testing and late diagnosis rates, is also assessed. METHODS: A self-administered questionnaire that was developed within the framework of the European project OptTEST was used to examine HIV knowledge and barriers to HIV testing scores before and after being involved in an HIV education program. A quasi-experimental design with pre- and post-intervention measures was performed to investigate its impact. We performed multivariable logistic regression analysis to assess the relationship between variables for the HIV testing offer. RESULTS: A total of 20 primary care centers and 454 primary care staff were included. Baseline OptTEST results showed that more knowledgeable staff offered an HIV test more frequently (OR 1.07; CI 95% 1.01-1.13; p = 0.027) and had lower barrier scores (OR 0.89; CI 95% 0.77-0.95; p = 0.005). Nurses had lower scores in knowledge-related items (OR 0.28; CI 95% 0.17-0.46; p<0.001), but higher scores in barrier-related items than physicians (OR 3.28; CI 95% 2.01-5.46; p<0.001). Specific centers with more knowledgeable staff members had a significant association with a greater level of new HIV diagnosis rates (OR 1.61; CI 95% 1.04-2.49; p = 0.032). After the intervention, we found that 12 out of 14 individual questions showed improved scores. In the 6 months after the training program, we similarly found a higher HIV testing rate (OR 1.19; CI 1.02-1.42; p = 0.036). CONCLUSIONS: This study highlights the association between knowledge and barriers to HIV testing, including HIV testing rates. It shows that it is possible to modify knowledge and reduce perceived barriers through educational programs, subsequently improving HIV screening outcomes.

RESUMO

This national audit demonstrated discrepancies between actual practice and that indicated by clinic policies following enquiry about alcohol, recreational drugs and chemsex use. Clinics were more likely to enquire about risk behaviour if this was clinic policy or routine practice. Previous testing was the most common reason for refusing HIV testing, although 33% of men who have sex with men had a prior test of more than three months ago. Of the group declining due to recent exposure in the window period, 21/119 cases had an exposure within the four weeks prior to presentation, but had a previous risk not covered by previous testing. Recommendations include provision of risk assessments for alcohol, recreational drug use and chemsex, documenting reasons for HIV test refusal, provision of HIV point-of-care testing, follow-up for cases at higher risk of HIV and advice about community testing or self-sampling/testing.

RESUMO

BACKGROUND: An evaluation of the 2010 ECDC guidance on HIV testing, conducted in October 2015-January 2016, assessed its impact, added value, relevance and usability and the need for updated guidance. METHODS: Data sources were two surveys: one for the primary target audience (health policymakers and decision makers, national programme managers and ECDC official contact points in the European Union/European Economic Area (EU/EEA) countries and one for a broader target audience (clinicians, civil society organisations and international public health agencies); two moderated focus group discussions (17 participants each); webpage access data; a literature citation review; and an expert consultation (18 participants) to discuss the evaluation findings. RESULTS: Twenty-three of 28 primary target audience and 31 of 51 broader target audience respondents indicated the guidance was the most relevant when compared with other international guidance. Primary target audience respondents in 11 of 23 countries reported that they had used the guidance in development, monitoring and/or evaluation of their national HIV testing policy, guidelines, programme and/or strategy, and 29 of 51 of the broader target audience respondents reported having used the guidance in their work. Both the primary and broader target audience considered it important or very important to have an EU/EEA-level HIV testing guidance (23/28 and 46/51, respectively). CONCLUSION: The guidance has been widely used to develop policies, guidelines, programmes and strategies in the EU/EEA and should be regularly updated due to continuous developments in the field in order to continue to serve as an important reference guidance in the region.

RESUMO

Renal toxicity in a 73-year-old male, using tenofovir/emtricitabine as preexposure prophylaxis, is described. Reduced renal reserve, a higher exposure to comedications and comorbidities can present a challenge when assessing the risks and benefits of tenofovir-based preexposure prophylaxis in the ageing population.

RESUMO

BACKGROUND: HIV infection leads to activation of coagulation, which may increase the risk for atherosclerosis and venous thromboembolic disease. We hypothesized that HIV replication increases coagulation potentially through alterations in extrinsic pathway factors. METHODS AND RESULTS: Extrinsic pathway factors were measured among a subset of HIV participants from the Strategies for Management of Anti-Retroviral Therapy (SMART) trial. Thrombin generation was estimated using validated computational modeling based on factor composition. We characterized the effect of antiretroviral therapy (ART) treatment versus the untreated state (HIV replication) via 3 separate analyses: (1) a cross-sectional comparison of those on and off ART (n=717); (2) a randomized comparison of deferring versus starting ART (n=217); and (3) a randomized comparison of stopping versus continuing ART (n=500). Compared with viral suppression, HIV replication consistently showed short-term increases in some procoagulants (eg, 15% to 23% higher FVIII; P<0.001) and decreases in key anticoagulants (eg, 5% to 9% lower antithrombin [AT] and 6% to 10% lower protein C; P<0.01). The net effect of HIV replication was to increase coagulation potential (eg, 24% to 48% greater thrombin generation from computational models; P<0.01 for all). The pattern of changes from HIV replication was reversed with ART treatment and consistent across all 3 independent comparisons. CONCLUSIONS: HIV replication leads to complex changes in extrinsic pathway factors, with the net effect of increasing coagulation potential to a degree that may be clinically relevant. The key influence of changes in FVIII and AT suggests that HIV-related coagulation abnormalities may involve changes in hepatocyte function in the context of systemic inflammation.

RESUMO

Improved methods for targeting HIV testing among patients most likely to be infected are required; HIDES I aimed to define the methodology of a European wide study of HIV prevalence in individuals presenting with one of eight indicator conditions/diseases (ID); sexually transmitted infection, lymphoma, cervical or anal cancer/dysplasia, herpes zoster, hepatitis B/C, mononucleosis-like illness, unexplained leukocytopenia/thrombocytopenia and seborrheic dermatitis/exanthema, and to identify those with an HIV prevalence of >0.1%, a level determined to be cost effective. A staff questionnaire was performed. From October 2009- February 2011, individuals, not known to be HIV positive, presenting with one of the ID were offered an HIV test; additional information was collected on previous HIV testing behaviour and recent medical history. A total of 3588 individuals from 16 centres were included. Sixty-six tested positive for HIV, giving an HIV prevalence of 1.8% [95% CI: 1.42-2.34]; all eight ID exceeded 0.1% prevalence. Of those testing HIV positive, 83% were male, 58% identified as MSM and 9% were injecting drug users. Twenty percent reported previously having potentially HIV-related symptoms and 52% had previously tested HIV negative (median time since last test: 1.58 years); which together with the median CD4 count at diagnosis (400 cell/uL) adds weight to this strategy being effective in diagnosing HIV at an earlier stage. A positive test was more likely for non-white individuals, MSM, injecting drug users and those testing in non-Northern regions. HIDES I describes an effective strategy to detect undiagnosed HIV infection. All eight ID fulfilled the >0.1% criterion for cost effectiveness. All individuals presenting to any health care setting with one of these ID should be strongly recommended an HIV test. A strategy is being developed in collaboration with ECDC and WHO Europe to guide the implementation of this novel public health initiative across Europe.

RESUMO

BACKGROUND: National guidance recommends targeted behavioural interventions and frequent HIV testing for men who have sex with men (MSM). We reviewed current policy and practice for HIV testing and behavioural interventions (BI) in England to determine adherence to guidance. METHODS: 25 sexual health clinics were surveyed using a semistructured audit asking about risk ascertainment for MSM, HIV testing and behavioural intervention policies. Practice was assessed by reviewing the notes of the first 40 HIV-negative MSM aged over 16 who attended from 1 June 2010, in a subset of 15 clinics. RESULTS: 24 clinics completed the survey: 18 (75%) defined risk for MSM and 17 used unprotected anal intercourse (UAI) as an indication of high risk. 21 (88%) offered one or more structured BI. Of 598 notes reviewed, 199 (33%) MSM reported any UAI. BI, including safer sex advice, was offered to and accepted by 251/598 (42%) men. A low proportion of all MSM (52/251: 21%) accepted a structured one-to-one BI as recommended by national guidance and uptake was still low among higher risk MSM (29/107: 27%). 92% (552/598) of men had one or more HIV test over a 1-year period. CONCLUSIONS: In 2010, the number of HIV tests performed met the national minimum standard but structured behavioural interventions were being offered to and accepted by only a small proportion of MSM, including those at a higher risk of infection. Reasons for not offering behavioural interventions to higher risk MSM, whether due to patient choice, a lack of staff training or resource shortage, need to be investigated and addressed.

RESUMO

BACKGROUND: UK guidelines recommend routine HIV testing in healthcare settings if the local diagnosed HIV prevalence >2/1000 persons. This prospective study assessed the feasibility and acceptability, to patients and staff, of routinely offering HIV tests in four settings: Emergency Department, Acute Care Unit, Dermatology Outpatients and Primary Care. Modelling suggested the estimated prevalence of undiagnosed HIV infection in attendees would exceed 1/1000 persons. The prevalence identified prospectively was not a primary outcome. METHODS: Permanent staff completed questionnaires assessing attitudes towards routine HIV testing in their workplace before testing began. Subsequently, over a three-month period, patients aged 16-65 were offered an HIV test by study staff. Demographics, uptake, results, and departmental activity were collected. Subsets of patients completed questionnaires. Analyses were conducted to identify factors associated with test uptake. FINDINGS: Questionnaires were received from 144 staff. 96% supported the expansion of HIV testing, but only 54% stated that they would feel comfortable delivering testing themselves, with 72% identifying a need for training. Of 6194 patients offered a test, 4105 (66·8%) accepted (61·8-75·4% across sites). Eight individuals were diagnosed with HIV (0-10/1000 across sites) and all transferred to care. Younger people, and males, were more likely to accept an HIV test. No significant associations were found between uptake and ethnicity, or clinical site. Questionnaires were returned from 1003 patients. The offer of an HIV test was acceptable to 92%. Of respondents, individuals who had never tested for HIV before were more likely to accept a test, but no association was found between test uptake and sexual orientation. CONCLUSIONS: HIV testing in these settings is acceptable, and operationally feasible. The strategy successfully identified, and transferred to care, HIV-positive individuals. However, if HIV testing is to be included as a routine part of patients' care, additional staff training and infrastructural resources will be required.

RESUMO

Sexual transmission of hepatitis C (HCV) between HIV positive men who have sex with men (MSM) is increasingly being reported. There is limited and conflicting data as to whether HIV negative MSM are at increased risk of infection. Local directorate guidelines recommended HCV testing only in MSM having a sexual transmitted infection (STI) screen who disclosed risk factors. In 2007 we introduced unselected screening into routine practice within our sexual health clinics. This report reviews the results of this change in our practice. Over 6 months, 3365 MSM attended for STI screening. Of 2309 MSM who agreed to be screened for HCV (69%) the prevalence of HCV was 0.65% (95% CI 0.36-1.1). This is similar to the prevalence of HCV in the general population within England. We conclude that unselected screening of MSM for HCV within our sexual health services is not currently justified.

RESUMO

The combination of intermittent subcutaneous IL-2 and highly active antiretroviral therapy in individuals infected with HIV-1 has been shown to have a beneficial quantitative effect on the CD4 T cell count. We observed IL-2-associated viral load 'blips' inducing HIV-1-specific lymphoproliferative responses at 24 weeks in such individuals. This immunotherapeutic approach, utilizing autologous virus as autovaccination, may be a viable, safer alternative to structured treatment interruption and potentially more efficacious than therapeutic vaccines.

RESUMO

These electrophysiological results show that the development of inflammation following peripheral injection of carrageenan into the paw is accompanied by alterations in the magnitude of the C-fibre evoked response of multireceptive dorsal horn neurones. The evoked response of the dorsal horn cells was found to either increase or decrease in the 3 h following the carrageenan injection, and the direction of this change was related to the degree of wind-up exhibited by the cell. Regardless of whether a cell was facilitated or inhibited by carrageenan, mu, delta and kappa opioids applied topically onto the spinal cord (equivalent to an intrathecal injection) exhibited increased antinociceptive potency. This increased effectiveness was especially marked for the mu opioid, morphine, which showed a 30-fold increase in potency. Interestingly the facilitations seen with the lowest doses of the mu and kappa opioids in this model in normal animals were absent after carrageenan. In addition, a very low dose of spinal naloxone caused a small but significant reduction in the C-fibre evoked responses. These results demonstrate that following peripheral inflammation, functional changes develop in both spinal transmission and modulatory systems. Alterations in the antinociceptive potency of opioid agonists occurs, with the mu agonist, morphine, showing the greatest change.
