A medical microbiologist/epidemiologist in the School of Pathology, Govender’s proposed research on bacterial and fungal infections in people with advanced HIV disease (or AIDS) will now, with this NIHR funding, be applied to assess a World Health Organization package of care.
Specifically, this package of care for people living with AIDS could be refined or expanded to prevent deaths from bacterial or fungal infections.
The NIHR Global Research Professorship scheme funds researchers to promote effective translation of research and to strengthen research leadership at the highest academic levels. It funds research that aims to specifically and primarily benefit people in low- and middle- income countries (LMICs).
NIHR Director of the Global Health Research Programme, Professor Kara Hanson, says: “The Global Research Professorship is our flagship award. It funds researchers to translate discoveries into enhanced interventions, diagnoses and treatments. This year, our Global Research Professors are working across a range of pertinent areas including sexual health, HIV/AIDS, mental health and multi-morbidities. I look forward to seeing how their research progresses and the difference their research will make to communities across the world.”
Reducing deaths from bacterial and fungal infections in people living with HIV
Professor Nelesh Govender’s research topic is Refining Interventions to Reduce AIDS Mortality from Bacterial and Fungal Infections in Africa.
According to Govender, at least one-third of the 630,000 global AIDS-related deaths are due to bacterial and fungal infections, which include cryptococcal meningitis, Pneumocystis jirovecii pneumonia (PCP), pneumococcal and Salmonella infections and histoplasmosis.
“From autopsy studies, we know that people with AIDS often die with multiple co-infections,” he says.
Meanwhile, some AIDS-related infections are unique to southern Africa. “We first described a fungus – Emergomyces africanus – causing a life-threatening infection in people with AIDS in 2013. Histoplasmosis, although found worldwide, is underdiagnosed in Africa because there is no access to simple accurate diagnostic tests.”
Histoplasmosis can be also mistaken for tuberculosis (TB). Opportunistic infections, such as PCP, pneumococcal and non-typhoidal Salmonella infections, occur everywhere in the world but are much more common in low-to-middle-income countries with a high prevalence of AIDS.
Govender says, “We used to see AIDS-related infections in people who were newly diagnosed with HIV. But we are increasingly seeing these infections in people who were previously diagnosed with HIV and started antiretroviral therapy [ART] but who then disengaged from care and stopped their ART.”
The Professorship award develops early-career researchers
Researcher-recipients of the NIHR Global Research Professorship scheme receive five-year awards of up to £2 million (±R46 million). This includes funding for early-career research and support posts. Researchers are also able to access a leadership and development programme.
Govender will collaborate with colleagues and partners in South Africa, Tanzania, the Democratic Republic of Congo, Mozambique, and Guinea.
“With the £2 million NIHR award, I can work full time on this research for five years. A team of postdoctoral and PhD students will also boost the Wits Mycology Research Division’s work,” says Govender.
Entrenched in the Global South
His NIHR Research Professorship will be led from the Faculty of Health Sciences at Wits and his research division at Wits Health Consortium. It will be conducted in partnership with South Africa’s National Institute for Communicable Diseases.
Govender will leverage his national and international networks, including the NIHR Global Health Research Group on HIV-associated Fungal Infections (IMPRINT), the EFFECT clinical trial, and GERMS-SA.
Govender’s IMPRINT colleagues (pictured above) include Dr Emily Prendergast (social scientist), Associate Professor David Lawrence (co-investigator), Professor Nelesh Govender, and Ms Tshiamo Mmotsa, a PhD student.
The ADVANCE-GERMS SA team (pictured above) includes Dr Rae Wake (clinical lead), Dr Vanessa Quan (programme lead), Ms Liliwe Shuping (epidemiologist), Professor Nelesh Govender, Ms Ruth Mpembe (lab manager), and Ms Nikiwe Power (project administrator).
The work will be divided into three broad areas:
- A 3-tiered cohort of adults with advanced HIV disease will be set up in South Africa to document the incidence, causes and outcomes of serious bacterial and fungal infections compared to tuberculosis (ADVANCE GERMS-SA).
- Patients with HIV will participate for researchers to understand their lived experience of being diagnosed and treated for serious bacterial and fungal infections and so that researchers can help answer questions about the acceptability and feasibility of a combination antifungal treatment regimen for cryptococcal disease being tested in the EFFECT clinical trial in South Africa and Tanzania.
- New laboratory tests, which detect traces of bacterial and fungal pathogens in body fluids, will be applied to cohort study patient samples and evaluated as diagnostic tools for serious infections among people living with advanced HIV disease
Throughout the project, the IMPRINT Community Advisory Board will oversee, guide and help to engage communities of people living with HIV in the research.
Applying for the Global Research Professorship award
The next round of the Global Research Professorship will open in late September 2024. It is open to health, public health and social care researchers. The eligibility has expanded to make it easier for LMIC-based applicants to apply. The NIRH now welcomes applicants employed by any Higher Education Institution (HEI) or Research Institute in a LMIC.
