Researcher tackling drug-resistant TB through molecular methods
Dr Anneke van der Spoel van Dijk is invested in contributing to the global effort of stopping TB by 2035.

The work of Dr Anneke van der Spoel van Dijk investigates the spread of TB in the Free State population using techniques such as next generation sequencing, spoligotyping and MIRU-VNTR typing. Dr Van der Spoel van Dijk, a senior medical scientist in the Department of Medical Microbiology at the University of the Free State (UFS) also looks at drug resistance in her research. This work informs decisions about how best to treat patients with multidrug-resistant TB (MDR-TB). 

She employs rapid molecular techniques to track one of Africa’s most serious diseases, tuberculosis (TB). 

Drug resistance
Scientists assist the National Health Laboratory Service and Department of Health in trying to refine the diagnostic tools to identify these cases earlier. Dr Van der Spoel van Dijk explains: “Until recently, it took up to two years to fine-tune treatment decisions for patients with MDR-TB. Patients get a cocktail of anti-TB drugs, but it takes time to find the right combination. Re-infection and relapse (patients stopping treatment for several reasons) add to the diagnostic and treatment management challenges.

Enormous impact
“Now doctors can reduce the time needed for diagnostic certainty to about seven days, while new drugs allow reduction of treatment from more than 18 to nine months. This can have an enormous impact on the life of many patients.”

Dr Van der Spoel van Dijk’s work forms part of research in the faculty looking at resistance development in TB strains. She is currently also doing her doctoral thesis on the differences and incidence of MDR-TB among adolescents versus adults. Dr Van der Spoel van Dijk says: “It is a complicated picture, but we hope to unravel it to support better diagnostic tools and patient care.”

As part of the National Health Laboratory Service, her department is playing an important role in TB diagnostics and the training of scientists and future pathologists. “Our work is contributing to the global vision to stop TB by 2035,” Dr Van der Spoel van Dijk says.

Medical team performs first hybrid procedure in the Free State
2014-12-08

The days when a heart operation meant hours in an operating theatre, with weeks and even months of convalescing, will soon be something of the past.

A team of cardiologists from the University of the Free State’s (UFS) Faculty of Health Sciences once again made medical history when they performed the first hybrid procedure in the Free State.

The Department of Paediatric Cardiology, in conjunction with the Department of Cardiothoracic Surgery, performed this very successful procedure on a 45-year-old woman from Kuruman.

During the procedure of 30 minutes, the patient’s thorax was opened up through a mini thoracotomy to operate on the beating heart.

“The patient received an artificial valve in 2011. Due to infection, a giant aneurism developed from the left ventricle, next to the aorta. Surgery would pose a very high risk to the patient. Furthermore, her health was such that it would contribute to problems during open-heart surgery,” explains Prof Stephen Brown, Head of the UFS’s Department of Paediatric Cardiology.

“After the heart was opened up through a mini thoracotomy, the paediatric cardiologists performed a direct puncture with a needle to the left ventricle cavity. A Special sheath was then placed in the left ventricle to bypass the catheters. Aided by highly advanced three-dimensional echocardiography and dihedral X-ray guidance, the opening to the aneurism, located directly below the artificial aorta valve, was identified and the aneurism cannulated.”
 
During the operation, a special coil, called a Nester Retractor, was used for the first time on a patient in South Africa to obtain stasis of extravasation and ensure the stability of devices in the aneurism.

“This is highly advanced and specialist work, as we had to make sure that the aneurism doesn’t rupture during manipulation and the devices had to be positioned in such a way that it doesn’t cause obstruction in valve function or the coronary artery. The surgical team was ready all the time to switch the patient to the heart-lung machine should something go wrong, but the procedure was very successful and the patient was discharged after a few days.”
