OVERVIEW

The Centre for Tuberculosis (CTB) was established in 2012. It was formerly known as the National TB Reference laboratory which was incorporated into the CTB with broader functions. In line with the mandate of the NICD, the CTB conducts laboratory-based public health surveillance of TB in South Africa. It continues to serve as a National TB reference laboratory (NTBRL) and was endorsed by the World Health Organization (WHO) as a supranational reference laboratory in 2016.

Global TB policies and guidelines are initiated through WHO and their formulation has included representation from the CTB which assisted in developing these strategic documents.

OBJECTIVES

The objectives of CTB are:

  • To conduct laboratory-based public health surveillance for drug sensitive TB, drug resistant TB and new drugs for the treatment of TB;
  • To provide specialized reference mycobacteriological services to South Africa and the African continent;
  • Apply innovative techniques such as next generation tools to improve the diagnosis and treatment of TB and drug resistant TB;
  • To initiate applied public health research aimed at providing enhanced intelligence on the drivers and protective factors that underlie the TB epidemic in South Africa; and
  • To advise and work closely with the Department of Health on strategic planning of the national TB program and formulate guidelines and policies for the diagnosis and treatment of TB in South Africa.

Functions

The CTB conducts and supports other countries to undertake population based survey and research to enhance our understanding of the disease burden and factors impacting on efforts aimed at controlling and eliminating TB and DR-TB. These are aimed at informing policy and practice.

Public Health Surveillance plays a critical role in informing and directing health responses and is a key activity of the CTB. Time series analysis is an important tool applied to monitor success or failure. Additional geospatial analysis is applied to define the epidemic and guide responses.

The centre serves not only as the NTBRL for South Africa, but also as the supranational reference laboratory in Africa. The services provided address complex clinical cases as well as programmatic support and quality assurance to laboratories locally and globally.

Treatment of drug resistant TB has evolved over the last couple of years with new and re-purposed drugs being included in the treatment regimens. The CTB performs drug susceptibility testing for the following new drugs: Bedaquiline, Clofazimine, Linezolid and Delamanid and monitors resistance to these agents.

Early detection ensures that correct treatment is instituted earlier aiding in the control of drug resistant TB.

Innovations are the key to success and the CTB has prioritised this aspect. This advancement is aimed at developing and evaluating novel approaches to improving diagnostic and treatment landscape for TB and DR-TB. The use of next generation technologies has expanded the horizon in addressing challenges with TB control and has been well established at the centre. Understanding transmission and latency are the other core themes being pursued at the CTB.

LEADERSHIP AND TEAM​

Centre head: PROF NAZIR ISMAIL

Prof Nazir Ismail was appointed in 2012 as the Head of the Centre for Tuberculosis, incorporating the WHO supranational TB Reference Laboratory at the NICD. He is a pathologist by training and is the lead tuberculosis researcher at NICD with a focus on TB epidemiology, public health responses and transmission.

Two major national studies were completed under his leadership, the SA National TB Drug Resistance survey 2012-14 and the trends in microbiologically confirmed TB nationally and sub-nationally. In addition, he has directed development and significant outputs in the field of genomics using next generation technologies. Lastly, transmission studies of DR-TB across SA are being conducted providing new knowledge in understanding drivers of TB in a high burden setting.
