Fighting COVID-19: Here is how we are helping

Farmovs — In 2019, FARMOVS was pre-qualified by the WHO to support clinical studies aimed at improving access to quality generic medicines across the globe.

The University of the Free State (UFS) is committed to supporting government’s efforts to overcome the COVID-19 pandemic. During this challenging time, dedicated staff members at the UFS continue to provide services as a testimony to their commitment to advance public knowledge of COVID-19 for the greater good of South Africa.

The following is a synopsis of the areas in which the UFS is actively assisting.

Public Health Emergency Solidarity Trial
Clinicians from the Department of Internal Medicine, the Department of Critical Care, and the Division of Virology will be working with FARMOVS to participate in the Public Health Emergency Solidarity Trial initiated by the World Health Organization (WHO). This international randomised trial will evaluate four treatment options (remdesivir, lopinavir/ritonavir, lopinavir/ritonavir plus interferon, chloroquine or hydroxychloroquine) for the treatment of COVID-19.

The trial is expected to include more than 45 countries worldwide, including a number of South African sites.

Farmovs
FARMOVS is in a planning process to support all the Bloemfontein hospitals, including Pelonomi, Universitas, 3 Military Hospital, Mediclinic, and Rosepark, in conducting the largest global trial on COVID-19 – the Public Health Emergency Solidarity Trial, under leadership of the WHO.

Negotiations are ongoing between the UFS and the Department of Health in the Free State for FARMOVS to offer support with the continuation of healthcare to non-COVID-19 patients in an attempt to free up space at Universitas Hospital for isolation of COVID-19 patients.

In 2019, FARMOVS was pre-qualified by the WHO to support clinical studies aimed at improving access to quality generic medicines across the globe. FARMOVS also receives feasibility requests for support with the evaluation of existing drugs (repurposing) as well as the development of novel drugs for the treatment of COVID-19 – this is an ongoing process.

Disaster Management Training and Education Centre (DiMTEC)
DiMTEC represents the UFS on the Provincial Joint Operation Centre (PROVJOC). The PROVJOC is a fully equipped, dedicated facility that is proactively established to enable all relevant role players /disciplines to jointly manage all safety and security-related aspects of any planned event or any major incident which has occurred or is imminent – especially in the response and recovery operations phase – at the strategic and/or tactical level, using the Unified Command System. This facility is also linked to all other established safety and security centres.

Research and Innovation
The UFS hosts a SARChI Research Chair in vector-borne and zoonotic diseases, and recently invested in the establishment of a biosafety level-3 facility. Hence, there is expertise on the campus to plan and conduct research on zoonotic and medically significant viruses. In addition, there are research groups focusing on protein expression systems with potential for utilisation in the development of diagnostic assays with application in either diagnosis or surveillance.

Currently, researchers at the UFS have established several projects that will contribute directly towards the COVID-19 outbreak.

Three heart-valve studies which have been developed at the Robert WM Frater Cardiovascular Research Centre at the School of Medicine at the University of the Free State (UFS) were recently presented in Monte Carlo at the conference of the prestigious global Heart Valve Society (HVS).

These studies are all headed by Prof Francis Smit, Head of the Department of Cardiothoracic Surgery at the UFS, and Manager of the Robert WM Frater Cardiovascular Research Centre.
Prof Smit says the HVS is a combination of the former heart-valve societies of Europe and the US. “Studies on heart-valve disease, heart-valve-related products and operations, as well as the design and development of new valves were presented. There are both clinical and development divisions.

He says the study in which the hemodynamics of their redesigned mechanical poppet valve was compared to a commercial bi-leaflet mechanical heart valve, was named as the best poster presentation in the experimental valve development and numerical flow dynamics division. The study, which was presented by Kyle Davis, mechanical engineer at the centre, competed against some of the best heart-valve research units in the world.

The redesigned valve, based on the 1960s Cape Town poppet valve, has the potential to provide a low-cost solution for mechanical heart-valve replacement. It is possible to produce the titanium ring with 3-D printers and is, together with the silicon poppet valve, extremely inexpensive compared to current mechanical valve-manufacturing processes.
The advantages of this valve over current mechanical valves is that, due to the effective and laminar flow characteristics, as well as the simple locking mechanisms, there is a reduced chance of valve thrombosis, and the need for anti-clotting drugs is therefore limited.

It was also confirmed that the new valve more than meets the published FDA (Federal Drug Agency) requirements, which determine the minimum standards of valves for human use in the US.

The redesigned valve also has a very low platelet activation impact, which is responsible for platelet thrombosis and leads to valve thrombosis or strokes. This valve is another heart-valve project by the centre, which is also in the process of evaluating a tri-leaflet polyurethane valve developed by them.
