Microbiology department receives Research Chair in Pathogenic Yeasts Prof Carlien Pohl-Albertyn

The National Research Foundation (NRF) recently approved a fifth research chair for the University of the Free State (UFS), the Research Chair in Pathogenic Yeasts. Prof Carlien Pohl-Albertyn from the Department of Microbial, Biochemical and Food Biotechnology, will be chairing this research chair. 

Activities of the Research Chair in Pathogenic Yeasts builds on existing research strengths and will contribute towards understanding pathobiology of medically significant pathogenic yeasts belonging to the genera Candida and Cryptococcus. 

According to Prof Pohl-Albertyn, the research group, established in 2014, is the only one in South African focusing on understanding the role of bioactive lipids in host-pathogen interaction as well as in the search for novel drug targets. The group brought together three principal investigators, Prof Pohl-Albertyn, Prof Koos Albertyn and Dr Olihile Sebolai, with knowledge regarding various virulence factors (including immunomodulatory metabolites) produced by the Candida and Cryptococcus as well as molecular biology of yeasts. Besides the three principal investigators, the group also includes five PhD students, nine MSc students, four BSc honours students as well as two postdoctoral fellows. 

Current projects of the group include the production of immunomodulatory compounds by the yeasts, finding novel targets for antifungal drugs and the interaction between the yeasts and different hosts using a variety of infection models. In addition, the interaction between pathogenic yeasts and other co-infecting pathogens is also being investigated. 

Why research on fungal infections?
“As a result of presently used treatments for diseases and HIV/Aids, and the advances in medical interventions, many diseases no longer pose a threat to humans and life expectancy is prolonged. However, this has also caused an increase in various opportunistic infections, and most of all, fungal infections.

“With an increase in the number of individuals sensitive to invasive fungal infections, yeasts have begun to be reported more frequently as pathogens (yeasts that can cause disease). Infections by pathogenic yeasts affect a wide variety of patients. Although most of them are immunosuppressed (including HIV positive) other underlying conditions may predispose people to such infections. These include extremes of age (premature infants and the elderly), diabetes, cancer and cystic fibroses. In addition, patients hospitalised in intensive care units, as well as patients undergoing major abdominal or thoracic surgery are at high risk of invasive candidiasis. Similarly, HIV/Aids, liver cirrhosis and immunosuppressive therapy are known risk factors for invasive cryptococcosis,” said Prof Pohl-Albertyn.

According to her an important hurdle in the treatment of invasive yeast infection is the emergence of drug resistance in these pathogens. Therefore, research into pathobiology, including new drug targets, as well as novel treatment options, is a necessity. 

In line with the UFS research strategy
The NRF call for research chairs, specifically aimed at female researchers at universities that currently have fewer than 15 research chairs, came out in May 2017.

The university considers the current SARChi Chairs and the possibility of future chairs as an integral and strategic initiative to increase its national and international standing through excellent academic and research leadership. A Research Chair in Pathogenic Yeasts is therefore an invaluable addition to the UFS Research Strategy. 

The Research Chair is for five years, and is renewable for three terms.

The Cardiology Research Unit at the University of the Free State (UFS) contributed largely to the evaluation of the drug Juxtapid (lomitapide), which was developed by the Aegerion pharmaceutical company and approved by the FDA (Federal Drug Administration). Together with countries such as die USA, Canada and Italy, the UFS’ Unit recruited and evaluated the most patients (5 of 29) for the study since 2008.  

The drug was evaluated in persons with so-called familial homozygous hypercholesterolemia (HoFH).  

Following its approval by the FDA, Juxtapid is now a new treatment option for patients suffering from HoFH. The drug operates in a unique way which brings about dramatic improvements in cholesterol counts.  

According to Prof. Hennie Theron, Associate Professor in the Department of Cardiology at the UFS and Head of the Cardiology Contract Research Unit, HoFH is a serious, rare genetic disease which affects the function of the receptor responsible for the removal of low-density lipoprotein cholesterol (LDL-C) (“bad” cholesterol) from the body. Damage to the LDL receptor function leads to extremely high levels of blood cholesterol. HoFH patients often develop premature and progressive atherosclerosis, which is a narrowing or blockage of the arteries.  

“HoFH is a genetically transmitted disease and the most severe form of hypercholesterolemia. Patients often need a coronary artery bypass or/and aortic valve replacement before the age of 20. Mortality is extremely high and death often occurs before the third decade of life. Existing conventional cholesterol-lowering medication is unsuccessful in achieving normal target cholesterol values in this group of patients.  

“The only modality for treatment is plasmapheresis (similar to dialysis in patients with renal failure). Even with this type of therapy the results are relatively unsatisfactory because it is very expensive and the plasmapheresis has to be performed on a regular basis.  

“The drug Juxtapid, as currently evaluated, has led to a dramatic reduction in cholesterol values and normal values were achieved in several people. No existing drug is nearly as effective.  

“The drug represents a breakthrough in the treatment of familial homozygous hypercholesterolemia. The fact that it has been approved by the FDA, gives further impetus to the findings,” says Prof. Theron.  

In future further evaluation will be performed in other forms of hypocholesterolemia.  

According to Prof. Theron, the findings of the study, as well as the recent successful FDA evaluation, once again confirms the fact that the UFS’ Cardiology Contract Research Unit is doing outstanding work.  

Since its inception in 1992, the Unit has already been involved in more than 60 multi-centre, international phase 2 and 3 drug studies. Several of these studies, including the abovementioned study, really affected the way in which cardiology functions.  

The UFS’ Cardiology Contract Research Unit is being recognised nationally and internationally for its high quality of work and is constantly approached for their involvement in new studies.
