Prof Motlalepula Matsabisa, Associate Professor in the Department of Pharmacology at the University of the Free State (UFS), has been appointed as the chairperson of the World Health Organisation’s (WHO) Regional Expert Advisory Committee on Traditional Medicines for COVID-19.
Prof Motlalepula Matsabisa, Associate Professor in the Department of Pharmacology at the University of the Free State (UFS), will lead Africa’s fight against the COVID-19 pandemic with his appointment as chairperson of the World Health Organisation’s (WHO) Regional Expert Advisory Committee on Traditional Medicines for COVID-19.

Prof Matsabisa has been chosen over 25 other experts from 27 African countries to head this expert committee tasked with setting up research and clinical trials for COVID-19 and beyond. The committee is also supported by the African Union (AU), the Centers for Disease Control and Prevention (CDC – Africa), and the European and Developing Countries Clinical Trials Partnership (EDCTP).

This committee was established by the WHO and the Africa CDC on 22 July with the aim of providing independent scientific advice and support to countries on the safety, efficacy, and quality of traditional medicine therapies. It is also an effort to enhance research and development of traditional medicines for COVID-19 in Africa.

Looking forward

“This is a huge continental and global responsibility being laid on my shoulders as a chairperson.  I have to keep the committee together and ensure that it delivers on its set mandate and terms of reference.  I need to ensure that the committee helps the continent and region to get the scientific and legislative aspects on traditional medicine development on track.”  

“I have taken this position and responsibility, knowing quite well what it entails. I want to do this for the continent and for the sake of good science of all traditional healers and consumers of traditional medicines on the continent and beyond,” says Prof Matsabisa.

According to Prof Matsabisa, he is looking forward to working with a team of dedicated experts from 27 countries in the African region, and being of help to countries that need assistance with clinical trials, including preclinical work to move to clinical research.

Prof Matsabisa says he is also looking forward to countries asking South Africa to be part of their multi-centre studies in clinical trials for traditional medicines, and to help set up clinical trial teams that include Western-trained clinicians to get into traditional medicine studies. 

The work of the committee

According to Prof Matsabisa, his new position took effect the same day as his appointment and will run as long as COVID-19 is part of our daily lives and even beyond. It entails supporting member states to implement the WHO master plan for clinical trial protocols in order to generate credible data for COVID-19 results, based on traditional medicines. The committee will also coordinate support to member states in the African region to collaborate on clinical trials of traditional medicine-based therapies – elevating standards by pooling expertise in multicentre studies, as well as complying with GCP and good participatory practice guidelines for trials of emerging and re-emerging pathogens.
“The committee will also advise on strengthening the capacity of national medicine regulatory authorities to accelerate the issuance of marketing authorisations for traditional medicine products that have been well researched for safety, efficacy, and quality, as well as to expedite the approval of clinical trials on traditional medicines. This will help to meet the national registration criteria and the WHO norms and standards of quality, safety, and efficacy for the management of COVID-19 and others.”

“It will also provide independent scientific advice to the WHO and other partners regarding policies, strategies, and plans for integrating traditional medicines into COVID-19 responses and health systems,” explains Prof Matsabisa. 

Aiming for the top spot 

Prof Matsabisa has been described as having the third highest research output – something he is not satisfied with. 
“I was disappointed that only one point separated me from the second place. I will push for first place as this is my ultimate aim. My motivation for this is simple – I like what I am doing, I do not take it as a job but do it because I love research.”  

“I always like to tell students that we should be proud to one day see products in the shops that we can relate to and to which we have contributed or that we have made.   This is what drives me and my staff.  I have a beautiful team of students, staff, and postdoctoral fellows who share my vision of research.  We all have a shared vision and strive to be relevant at all times in science research, development, and teaching.”

• Prof Matsabisa was recently part of a national conference with the theme: Harnessing science, technology, and innovation in response to COVID-19: A national and international effort. The conference was hosted by Dr Blade Nzimande, Minister of Higher Education, Science and Innovation, with Pres Cyril Ramaphosa, Dr Zweli Mkhize, Minister of Health, Ebrahim Patel, Minister of Trade, Industry and Competition, Prof Sarah Anyang Agbor, African Union Commissioner for Human Resources, Science and Technology, and Dr Tedros Adhanom Ghebreyesus, Director-General of the World Health Organisation, in attendance.

Fight against Ebola virus requires more research

Dr Abdon Atangana, a postdoctoral researcher in the Institute for Groundwater Studies at the University of the Free State (UFS), wrote an article related to the Ebola virus: Modelling the Ebola haemorrhagic fever with the beta-derivative: Deathly infection disease in West African countries.

“The filoviruses belong to a virus family named filoviridae. This virus can cause unembellished haemorrhagic fever in humans and nonhuman monkeys. In literature, only two members of this virus family have been mentioned, namely the Marburg virus and the Ebola virus. However, so far only five species of the Ebola virus have been identified, including:  Ivory Coast, Sudan, Zaire, Reston and Bundibugyo.

“Among these families, the Ebola virus is the only member of the Zaire Ebola virus species and also the most dangerous, being responsible for the largest number of outbreaks.

“Ebola is an unusual, but fatal virus that causes bleeding inside and outside the body. As the virus spreads through the body, it damages the immune system and organs. Ultimately, it causes the blood-clotting levels in cells to drop. This leads to severe, uncontrollable bleeding.

Since all physical problems can be modelled via mathematical equation, Dr Atangana aimed in his research (the paper was published in BioMed Research International with impact factor 2.701) to analyse the spread of this deadly disease using mathematical equations. We shall propose a model underpinning the spread of this disease in a given Sub-Saharan African country,” he said.

The mathematical equations are used to predict the future behaviour of the disease, especially the spread of the disease among the targeted population. These mathematical equations are called differential equation and are only using the concept of rate of change over time.

However, there is several definitions for derivative, and the choice of the derivative used for such a model is very important, because the more accurate the model, the better results will be obtained.  The classical derivative describes the change of rate, but it is an approximation of the real velocity of the object under study. The beta derivative is the modification of the classical derivative that takes into account the time scale and also has a new parameter that can be considered as the fractional order.  

“I have used the beta derivative to model the spread of the fatal disease called Ebola, which has killed many people in the West African countries, including Nigeria, Sierra Leone, Guinea and Liberia, since December 2013,” he said.

The constructed mathematical equations were called Atangana’s Beta Ebola System of Equations (ABESE). “We did the investigation of the stable endemic points and presented the Eigen-Values using the Jacobian method. The homotopy decomposition method was used to solve the resulted system of equations. The convergence of the method was presented and some numerical simulations were done for different values of beta.

“The simulations showed that our model is more realistic for all betas less than 0.5.  The model revealed that, if there were no recovery precaution for a given population in a West African country, the entire population of that country would all die in a very short period of time, even if the total number of the infected population is very small.  In simple terms, the prediction revealed a fast spread of the virus among the targeted population. These results can be used to educate and inform people about the rapid spread of the deadly disease,” he said.

The spread of Ebola among people only occurs through direct contact with the blood or body fluids of a person after symptoms have developed. Body fluid that may contain the Ebola virus includes saliva, mucus, vomit, faeces, sweat, tears, breast milk, urine and semen. Entry points include the nose, mouth, eyes, open wounds, cuts and abrasions. Note should be taken that contact with objects contaminated by the virus, particularly needles and syringes, may also transmit the infection.

“Based on the predictions in this paper, we are calling on more research regarding this disease; in particular, we are calling on researchers to pay attention to finding an efficient cure or more effective prevention, to reduce the risk of contamination,” Dr Atangana said.
