Today we will discuss different types of HIV and Syphilis antibody testing performed at home by the patient or consumer. Home testing for HIV and Syphilis empower people, especially pregnant women who live in remote areas or are marginalised and hard to reach, to screen themselves for these two serious and communicable infections at home and seek additional confirmitory testing, treatment and support if their screening test is reactive. We will discuss what these tests are, how they can be used as well as review their merits and potential risks.

Host: Dr Fabiola Martin, Sexual Health Specialist, Associate Professor at Australian National University

Guest: Dr Bobbie Van Der Pol, Professor of Medicine and Public Health at the University of Alabama at Birmingham, the Director of the UAB STD Diagnostics Laboratory and President of the International Society for STD Research.

Today we will discuss if screening asymptomatic Men who have sex with Men, also referred to as MSM, who are receiving HIV pre-exposure anti-retroviral medication, called HIV PrEP, routinely for bacterial STIs, gonorrhoea and chlamydia through pharyngeal, urine and rectal PCR testing every three months- also referred to as 3x3 testing is indeed of benefit or may cause harm. This year, in Lancet HIV, the Gonoscreen trial, a randomised controlled trial, of 500 MSM on PrEP in each arm followed up for 12 months reported that 3x 3 testing does not reduce the incidence of gonorrhoea and chlamydia infections in this specific cohort. In Belgium, this trial has led to a change in clinic practice through the Belgium HIV PrEP guidelines where patients will be screened less frequently and intensely. Lancet ID on the other hand published an opinion piece by Raccagni et al where concerns about transmission and morbidity risk of untreated infection and implications of using poor quality screening tools are voiced. We will discuss today the merit of the Gonoscreen trial and other studies that support a decrease in screening & treating asymptomatic bacterial STIs and exercising stricter antimicrobial stewardship versus the risks associated with leaving asymptomatic infections untreated and risking morbidity and transmission.

Today we provide you with an update on the sexually transmitted infection: Trichomonas vaginalis, a protozoan which infects the vagina, urethra and paraurethral glands. It is an uncommon cause of vaginal discharge and penile urethritis and can persist for a long time if left untreated. Up to 50% of people with vaginal infections and especially people with urethral infections remain asymptomatic. Persistent trichomonas infection has been associated with facilitating the transmission of human immunodeficiency virus (HIV) and adverse poor reproductive health outcomes. Dr Christina Muzny, Professor in Infectious Diseases at University of Alabama, Birmingham, USA, will present on published clinical trial data on novel treatment against trichomoniasis.

You will recall a previous podcast about preventing Neisseria gonorrhoea through an effective vaccine. Neisseria gonorrhoeae is a ubiquitous sexually transmitted bacteria that can cause both localised and systemic disease if left untreated. It may be transmitted to neonates. We also reported on a rise of the gonorrhoea incidence, as well as increasing rates of antibiotic resistance.

Today we will revisit the implementation of vaccinations against gonorrhoea in the UK. Here is an exciting up-date on the advice provided by UK's Joint Committee on Vaccination and Immunisation, JCVI, on using the vaccine 4CMebB OMV against Meningococcus used off-label for the prevention of gonorrhoea infection

Today we will focus on the alternative treatments of early Syphilis. Worldwide many of us have experienced a shortage of gold standard treatment benzathine benzylpenicillin injections for syphilis. It is time we look for alternative antibiotic treatments and prevention strategies for syphilis. In conversation with Prof Jeffery Klausner, Professor of Medicine, Infectious Diseases and Public Health at the Keck School of Medicine of the University of Southern California, we will discuss a new study published in the Lancet in 2024. Mitja O. et al compared oral linezolid with benzathine penicillin G for treatment of early syphilis in adults (Trep-AB Study) in Spain, which is a prospective, open-label, non-inferiority, randomised controlled trial.

In our final episode in honour of the World AIDS Day we have a conversation with Assistant Prof. Rajasuriar, who coordinates the translational research program in HIV immunology and Ageing at the Centre of Excellence for Research in AIDS (CERiA) in Kuala Lumpur, Malaysia. Today, thanks to effective HIV antiretroviral therapy, people living with HIV can live long and healthy lives. According to the latest data from the Centers for Disease Control and Prevention (CDC), in 2021, of the nearly 1.1 million people living with diagnosed HIV in the United States and dependent areas, over 53% were aged 50 or older. Hosted by: Dr Fabiola Martin, the BMJ STI Podcast editor and Sexual Health Specialist based in Australia and Senior Clinical Lecturer at School of Public Health at University of Queensland.

Today we are honouring the World AIDS Day on 1st December in 2023, by focusing on young people who live with HIV. Adolescents and young people represent a significant share of people living with HIV worldwide. In 2022 alone, 255,000-760,000 young people between the ages of 10 to 24 were newly infected with HIV, of whom 35,000-250,000 were adolescents between the ages of 10 and 19. In conversation with Prof Natella Rakhmanina, who is a Professor of Paediatrics at the George Washington University and the Director of the HIV Program at Children's National Hospital, we will discover the pro & cons of long-acting antiretrovirals to mange HIV infection in young people. Hosted by: Dr Fabiola Martin, the BMJ STI Podcast editor and Sexual Health Specialist based in Australia and lecturer at School of Public Health at University of Queensland.

Welcome to the 4th episode of the 2023 BMJ Sexually Transmitted Infections Podcast Series. This year the International AIDS Society Conference was held for the first time in Brisbane Australia in July 2023. It was wonderful to learn about many new research findings, community perspectives and to connect with old friends and make new ones. Today we will provide you with some of the many clinical, vaccine and policy research highlights of this conference and share our subjective perspectives. We were joined by: Dr Ming Lee, a sexual health & HIV physician and UK MRC Clinical Research Training Fellow at Imperial College London, London, UK, Prof Damian Purcell, Head of the Molecular Virology Laboratory in the Department of Microbiology and Immunology at the Peter Doherty Institute, University of Melbourne, Melbourne, Australia, Dr Meg Doherty, Director of Global HIV, Hepatitis and Sexually Transmitted Infection Programmes at World Health Organization, Heath Quarter.
