Understanding the public health value and defining preferred product characteristics for therapeutic human papillomavirus (HPV) vaccines: World Health Organization consultations, October 2021-March 2022.

The World Health Organization (WHO) global strategy to eliminate cervical cancer (CxCa) could result in >62 million lives saved by 2120 if strategy targets are reached and maintained: 90% of adolescent girls receiving prophylactic human papillomavirus (HPV) vaccine, 70% of women receiving twice-lifetime cervical cancer screening, and 90% of cervical pre-cancer lesions and invasive CxCa treated. However, the cost and complexity of CxCa screening and treatment approaches has hampered scale-up, particularly in low- and middle-income countries (LMICs), and new approaches are needed. Therapeutic HPV vaccines (TxV), which could clear persistent high-risk HPV infection and/or cause regression of pre-cancerous lesions, are in early clinical development and might offer one such approach. During October 2021 to March 2022, WHO, in collaboration with the Bill and Melinda Gates Foundation, convened a series of global expert consultations to lay the groundwork for understanding the potential value of TxV in the context of current CxCa prevention efforts and for defining WHO preferred product characteristics (PPCs) for TxV. WHO PPCs describe preferences for vaccine attributes that would help optimize vaccine value and use in meeting the global public health need. This paper reports on the main discussion points and findings from the expert consultations. Experts identified several ways in which TxV might address challenges in current CxCa prevention programmes, but emphasized that the potential value of TxV will depend on their degree of efficacy and how quickly they can be developed and implemented relative to ongoing scale-up of existing interventions. Consultation participants also discussed potential use-cases for TxV, important PPC considerations (e.g., vaccine indications, target populations, and delivery strategies), and critical modelling needs for predicting TxV impact and cost-effectiveness.

Incidence of hepatitis-C among HIV infected men who have sex with men (MSM) attending a sexual health service: a cohort study.

BACKGROUND: We aimed to determine the incidence of Hepatitis C (HCV) infection among HIV-infected men who have sex with men (MSM) attending a Sexual Health Centre. METHODS: A retrospective cohort study was carried out among HIV-infected MSM seen at least once between February 2002 and March 2010. The analysis was restricted to MSM who had had a negative HCV antibody test at least 6 months after their diagnosis for HIV. Duration of follow up was taken from the date of HIV diagnosis to the first positive or last negative HCV antibody test. RESULTS: During the time 1445 HIV-infected men attended the clinic of whom 1065 (74%) were MSM. Of these, 869 (82%) were tested for HCV at any time after HIV diagnosis. Of these 869, 69% (620) tested HCV negative at least 6 months after their HIV diagnosis. These 620 men had a mean age of 34 years (range 17-72) at HIV diagnosis and a total of 4,359 person years (PY) of follow up. There were 40 incident cases of HCV, of which 16 were in injecting drug users (IDU) and 24 in non-IDU. The overall incidence of HCV among HIV-infected MSM was 0.9/100 PY (95% CI 0.6-1.2). The incidence among HIV-infected IDU was 4.7/100 PY (95% CI 2.7-7.5) while the incidence among HIV-infected non-IDU was 0.6/100 PY (95% CI 0.4-0.8) (hazard ratio of 8.7 and 95% CI 4.6-16.6, P < 0.001).The majority (78%) were tested for HCV because they developed abnormal liver transaminases (n = 31) or hepatitis symptoms (n = 2), while others (n = 7) were identified through routine HCV testing. CONCLUSION: A considerable proportion of HIV-positive MSM who did not inject drugs contracted HCV, presumably via sexual transmission and the main trigger for investigation was abnormal liver transaminases.

Advertising sexual health services that provide sexually transmissible infection screening for rural young people - what works and what doesn't.

BACKGROUND: 'TESTme' is a sexually transmissible infection (STI) screening service for Victorian young people living in rural areas. We evaluated the effectiveness of advertising for this service over an 11-month pilot period. METHODS: The advertising that was used included websites, a Facebook page, posters, flyers, business cards, wrist bands and professional development sessions for health nurses that occurred throughout the pilot period. We also used once-off methods including advertisements in newspapers, student diaries and short messages to mobile phones. RESULTS: Twenty-eight clients had a consultation through TESTme. Twenty found the service through health professionals, six through the Melbourne Sexual Health Centre (MSHC) web page, one through the Facebook page and one through the student diary. The total direct costs incurred by the centre for advertising were $20850. The advertising cost per client reached for each advertising method was $26 for health professionals, $80 for the MSHC web advertisement, $1408 for Facebook and $790 for the student diary. Other advertising methods cost $12248 and did not attract any clients. CONCLUSION: Advertising STI health services for rural young people would be best to focus on referrals from other health services or health care websites.

Evaluation of Health Map: a patient-centred web-based service for supporting HIV-infected patients.

BACKGROUND: Our aim was to describe the use of and responses to a self-management website, 'Health Map', established to address the key chronic health issues of HIV-positive people. METHODS: Health Map assessed health issues against current recommendations for: treatment adherence, monitoring CD4 counts and viral load, psychological health and physical activity, vaccination, cholesterol, fasting blood sugar, blood pressure, alcohol consumption, smoking, body mass index, and cervical screening for women and sexually transmissible infection (STI) screening for men who have sex with men (MSM). RESULTS: A total of 552 people, with a mean age of 37 years, completed the full 'Health Map' program, of whom 536 (97%) were Australian, 425 (77%) were male, including 268 (63%) MSM. Online responses to several health indices were of concern: 49% missed at least one dose of antiretroviral therapy per month and only 41% had had an HIV viral load test in the 4 months prior. Only 43% reported regular physical activity, and 49% and 61% reported vaccination for hepatitis A and B. The proportion tested within the recommended periods for fasting cholesterol (40%), fasting blood sugar (35%) and cervical screening (43%) in women or STI screening for MSM (53%) were low. CONCLUSIONS: A substantial proportion of individuals completing the online survey reported information that would suggest their HIV and more general health care is suboptimal. These data are consistent with community surveys and indicate the need for improvement in the chronic management of HIV.
