Funding applications invited for research projects or PhD Studentship: 2025 Round

We invite researchers in various fields related to sexual health, HIV and other sexually transmitted infections to apply for funds to undertake:

  1. Original research
  2. Topic-based commissions
  3. Part funding of PhD Studentship

Sexually Transmitted Infections Research Foundation (STIRF) was set up to pump prime research projects relating to the epidemiology, pathophysiology, management, and health care delivery of sexually transmitted infections and HIV in the

East Midlands – East Midlands Deanery
North east and north Cumbria –  HEE North East
North west – North West Postgraduate Medicine and Dentistry
West Midlands – West Midlands Deanery
Yorkshire and Humber – Yorkshire and Humber Deanery

The primary aim is to provide initial funding to allow promising projects from researchers early in their career to obtain preliminary results as a prelude to acquire further funds from larger funding bodies.

We invite applications from researchers in the above regions on projects or part funding of PhD Studentships relating to sexual health, sexually transmitted diseases and HIV. All projects will be initially screened by the Scientific Committee of STIRF and those considered suitable will be sent for peer review by experts in the field.

The following fields of research will be considered in relation to sexual health, STIs and HIV:

  • Epidemiology of HIV and other sexually transmitted diseases
  • Research on HPV and other sexually transmissible malignancies
  • Health care delivery including views of clients
  • Issues relating to deprived or marginalised communities.
  • Pathophysiology of diseases and syndromes
  • Inter-relationship between diseases
  • Treatment modalities
  • Complications of treatment and co-morbidities

STIRF is also interested in commissioning work based on specific priority topics for research. Applicants should supply a brief (no more than one A4 size) preliminary application, outlining the following:

  • title
  • the proposed research question
  • justification for why this should be a research priority
  • a brief outline of the research methodology proposed to answer the research question
  • existing resources which are available to the researchers
  • a provisional estimate of the total grant requested

A more detailed application will be requested if appropriate following review of the preliminary application.

Applications for research grants should not exceed £60,000 in the first year. Depending on satisfactory reports a further £30,000 may be available for the second year. Joint funding with other grant giving bodies will be considered. Applications for part funding of PhD Studentship should not exceed a maximum of £70,000 over 3-4 years

Daily pri-exposure prophylaxis (PrEP) prevents HIV infection in high risk gay men

Daily HIV medicine taken by men who have sex with men (MSM) reduces risk of HIV infection by 86% as was reported by Molina J-M, and colleagues in the ANRS Ipergay trial  at the Conference on Retroviruses and Opportunistic Infections held in Seattle, USA in 2015 (23LB.).

Molina et al reported the final results of a three year study which randomised MSM who were negative for HIV to either take daily HIV prophylaxis with two anti-retroviral drugs in a single tablet immediately or deferred for 1 year.

The study showed that those taking the drugs on a daily basis have a 86% reduction in the risk of being infected by HIV than MSM not taking the drug (p=0.0001). The trial was stopped in October of 2014 and all participants in the  deferred group were offered pre-exposure prophylaxis (PrEP)

As a Lancet editorial commented:

The science is now clear: oral pre-exposure prophylaxis (PrEP) with a coformulation of tenofovir disoproxil fumarate and emtricitabine (Truvada) significantly reduces the risk of HIV infection among individuals at high risk of HIV infection.

The news that PrEP has shown consistent efficacy among those who take it as prescribed should be a cause for celebration, and galvanise action to ensure access to PrEP for those who could benefit the most. But almost 3 years since the US Food and Drug Administration approved tenofovir–emtricitabine for PrEP little is being done on implementation.

With more than 2 million new HIV infections every year worldwide, it is time for that to change.

Start HIV treatment regardless of CD4 count

A large international study (INSIGHT START) published in the New England Journal of Medicine has found that starting antiretroviral therapy immediately after human immunodeficiency virus (HIV) diagnosis rather than waiting until a patient’s CD4+ count has declined is of considerable benefit.

The results of the study were also released at the International AIDS Society conference in Vancouver, Canada, on 20 July.

Currently most authorities strongly recommend starting anti-HIV once CD4+ count drops to below 350 cells per cubic millimetre. Until the INSIGHT START study there was no randomized trials  showing the benefits and risks of initiating antiretroviral therapy in patients with asymptomatic HIV infection who have a CD4+ count of more than 350 .

START study conducted in 35 countries randomly assigned 4,685 HIV positive patients to either receive immediate antiretroviral therapy (median CD4+ of 650) or wait until their counts fell to below 350.

After a mean follow up of 3 years the study found that 42 patients in the immediate-initiation group died, as compared with 96 patients in the deferred-initiation group  (95% confidence interval, 0.30 to 0.62; P<0.001). Reduction in deaths were largely from tuberculosis, Kaposi’s sarcoma, and malignant lymphomas – conditions that can occur in HIV-infected individuals with only moderately damaged immune systems.

Currently the WHO requires all patients with HIV to be treated CD4+ of 500 or less. WHO may need to extend that to treating anyone at diagnosis. This would not only benefit the individual but by reducing viral shedding in body secretions reduce transmission and hence have a public health benefit. Moreover some of the costs of starting early would be offset by not needing to perform repeated CD4+ counts.

Important new research on lymphogranuloma venereum (LGV) in gay men in the UK

Lymphogranuloma venereum (LGV), previously predominantly a tropical disease, re-emerged in Western Europe in 2003, and has arguably now regained endemic status in many countries. It remains largely contained within in a population of men who have sex with men (MSM) with high rates of other sexually transmitted infections (STIs) including HIV, though a first female case was reported in Sexually Transmitted Infections in 2012.

A recent series of papers in Sexually Transmitted Infections sheds further light on the risk factors for rectal LGV in men who have sex with men in the UK, the key symptoms and ways in which LGV presents to the clinician, and pitfalls in the currently recommended treatment and prevention strategies.

Moreover, microbiological  characteristic of LGV repeaters using surveillance data has convinced Rönn and colleagues that behaviour alone does not explain reinfection, which they see as related to centrality in sexual networks.

Together these four articles add important information on the clinical presentation, epidemiology and treatment of LGV in MSM.

Need and acceptability of human papillomavirus (HPV) vaccination in men

HPV vaccination of young women with the quadrivalent vaccine (HPV4) resulted in a dramatic fall in genital warts and cervical cancer rates. However rolling out a similar vaccination in young men has been hampered by arguments that  male HPV4 vaccination programmes exceed cost-effectiveness thresholds.

Unlike the USA and Australia, European countries do not include men in HPV vaccination programmes, instead focusing on achieving expanded coverage among women to promote herd immunity.

Yet there is  evidence that HPV4 vaccination offers substantial clinical benefits to men and is cost effective among men who have sex with men (MSM). MSM have largely been excluded from mathematical models. A recent study in the journal Sexually Transmitted Infections has shown that HPV related conditions such as anal/genital warts and rectal infections are likely to be profoundly underdiagnosed among MSM in most European cities. The paper concluded that there is an urgent need to improve sexual healthcare tailored to MSM at risk for STIs.

There is also the argument  for a gender-neutral (universal) approach to vaccination.

In the same issue of STI a meta-analysis shows that there are currently a number of obstacles to acceptability of HPV vaccination in  men. They concluded that Public health campaigns should aim to promote positive HPV vaccine attitudes and awareness about HPV risk in men. The paper recommended interventions to promote HPV vaccination for boys and to overcome  obstacles to HPV vaccine acceptability for men.

Trichomonas vaginalis – a neglected STI with major global health implications

Trichomonas vaginalis (TV) is the most prevalent curable sexually transmitted infection (STI) globally. Yet at least 80% of TV infections are asymptomatic, though even asymptomatic infections are a public health concern.

In addition to the risk of transmission to sex partners, TV infection has been associated with as much as a 2.7-fold increase in the risk of HIV acquisition, a 1.3-fold increase in the risk of preterm labour, and a 4.7-fold increase in the risk of pelvic inflammatory disease.

A recent review in the journal Sexually Transmitted Infections (STI) highlights the current knowledge of the global epidemiology of TV infection. These include sex differences in the incidence and prevalence of infection, and the potentially important role of female sex hormones, and the menstrual cycle in mediating TV susceptibility and natural history.

WHO has estimated that over half the 248 million new TV infections each year occur in men. By contrast, 89% of prevalent TV cases are found among women. Biological differences between the sexes contribute to these striking differences between men and women.

There has also been an increased understanding of the mechanisms underlying resistance to metronidazole – the current sole drug available to eradicate the organism.

Recent innovations in detection, including the availability of nucleic acid amplification tests (NAATs), have improved our understanding of the natural history of TV infections. These innovations and our increased understanding of this common sexually transmitted infection should help us combat the global epidemic in TV.

Rising gonorrhoea antimicrobial resistance in Europe

A recent report by the European Centre for Disease Prevention and Control has highlighted the danger that rising antibiotic resistance may mean that soon gonorrhoea may become an untreatable disease in some parts of Europe.

According to the report the most worrying result is the increase in the percentage of isolates with decreased susceptibility to cefixime and the increase in the number of countries where this phenotype was identified between 2009 and 2010. [Fig 1]

 

Fig 1. European Centre for Disease Prevention and Control

Patient characteristics of isolates with decreased susceptibility did not differ greatly when compared to the overall population, except for age: patients with decreased susceptibility to cefixime were more likely to be older.

There is some evidence that the rates of ciprofloxacin and azithromycin resistance have both decreased since 2009. However they remain worringly high across Europe (53% and 7%, respectively).

Similar results for cefixime – which is the first line drug therapy in many centres – have been reported by the European gonococcal antimicrobial surveillance programme (Euro-GASP) – Fig 2

Dramatic drop in health spending according to OECD

Growth in health spending slowed or fell in real terms in 2010 in almost all OECD countries, reversing a long-term trend of rapid increases, according to OECD Health Data 2012.

In real terms average health spending has declined by over 6% compared to the start of the millenium.

Overall health spending grew by nearly 5% per year in real terms in OECD countries over the period 2000-2009, but this was followed by zero growth in 2010. Preliminary figures for a limited number of countries suggest little or no growth in 2011. The halt in total health spending in 2010 was driven by a fall of 0.5% in public spending for health, following an increase of over 5% per year in 2008 and 2009.

While government health spending tended to be maintained at the start of the economic crisis, cuts in spending really began to take effect in 2010. This was particularly the case in the European countries hardest hit by the recession.
