Centre for Lung Infection and Immunity (CLII)

The CLII seeks to enhance the prevention, diagnosis, and effective management of pulmonary infections including TB. Our mission, through our academic and clinical activities, is to reduce mortality, and improve the health-related quality of life of people with lung infections associated with poverty (TB, HIV and pneumonia).

"TB is the biggest infectious diseases killer known to mankind and, remarkably, killed over a billion people over the last 3 centuries! This is more deaths than in all the wars ever fought by mankind!"
"The problem of antimicrobial resistance, including that to TB (MDR-TB and XDR-TB), will cost the global economy US$ ~100 trillion per year by 2050!"

RELEVANCE

Prevention, diagnosis, and effective management of pulmonary infections including TB

EXCELLENCE

Internationally competitive translational research

RESPECT

Improving quality of life of those with diseases of poverty
By the time you you’ve finished reading this webpage about 30 people would have died of TB globally. Thus, the disease is far from eradicated! A resurgent epidemic of drug-resistant TB (MDR-TB, XDR-TB, and incurable TB) is now threatening TB control in several regions of the world.

The Centre

With the dual goals of scientific excellence and building research capacity that is sustainable and relevant to the health needs of the population the CLII has amassed a formidable track record in medical research and training. The Centre currently encompasses approximately 50 staff and students and undertakes laboratory based and clinically oriented studies. It has published a substantial body of work focussed on TB diagnostics, and the epidemiology and management of drug-resistant TB with articles in leading international journals. The most recent clinical trial on urine LAM, a biomarker for TB disease, showed it can save lives and was published in The Lancet. The Centre also provides consultative services and policy recommendations to the Western Cape Government and the South African National Department of Health.

With the aid of funding from the European Commission, EDCTP, South African MRC and DST, NIH, Wellcome Trust, Gates Foundation and others the CLII also engages in extensive capacity development and networking activities across Southern Africa. Over 12 African PhD students have already graduated, with several more in the pipeline, including candidates with a background in laboratory science and specialised clinical medicine (specialist physicians, dermatologists, neurologists, and pulmonologists). The Centre collaborates with a number of formerly disadvantaged institutions within South Africa. In addition, the CLII regularly hosts visitors, including PhD and Masters students from across the globe including the USA, Australia, Canada, Germany, Italy India, Nigeria, UK, USA, Zambia and Zimbabwe.

Considerable networking with other African sites has been achieved through the EDCTP-funded TB-NEAT project (SA, Zambia, Zimbabwe and Tanzania), XACT studies (SA and Zimbabwe) and other projects including TBsusgent, SA NRF Research Chair Initiative, and SA MRC CDA etc. The CLII is also part of the South African TESA Network of Excellence (linking 8 Southern African countries) and has contributed significantly to teaching and training, and networking within this consortium. Major achievements of the TB NEAT consortium include the LAM RCT and the Xpert RCT both published in The Lancet. Thus, much needed and considerable teaching, training, capacity development, and advocacy has been created for MDR & XDR-TB and TB diagnostics.

The research laboratories within the Department of Medicine at the University of Cape Town Groote Schuur site have been enhanced, including installation of a 9-colour LSR2 flow cytometer and establishment of database management, bioinformatics capability and facilities for biobanking. A new laboratory clean room suite is currently under construction.

In addition considerable investment infrastructure has been made at several sites which, in addition to augmenting research capacity, have benefitted healthcare workers and patients. This has included improvements to the clinical infrastructure at Langa, Gugulethu, Brooklyn Chest Hospital and Chapel Street clinics in Cape Town. Clinical office and patient consulting space has been built, and sputum induction facilities and sputum booths have been installed.

A new clinical profiling research facility for cough aerosol sampling has been installed at Brooklyn Chest Hospital. This second such facility on the continent of Africa is used to study tuberculosis transmission as these state of the art facilities enable identification of patients with XDR-TB who are the most infectious. A CLII led US NIH-funded study is currently being conducted.

The CLII regularly convenes research courses and seminars often including international faculty that are attended by African physicians and trainees. These include a forthcoming workshop on genome sequencing and drug resistance and a course entitled ‘Meeting the challenge of drug resistant tuberculosis’. Other events include an Advanced TB Diagnostics Course (co-convened in the past with Prof Madhu Pai and Prof Karen Steingart), and TB and Pulmonary Care Updates for Primary Care Practitioners.

Progress in Diagnosing TB

The fight against TB continues. And health professionals are making strides in monitoring and identifying new cases. A study conducted in Mitchell’s Plain and Klipfontein utilises a low-cost scalable mobile mini-clinic, operated by two health care workers. The clinics portable battery-operated DNA-based diagnostics tools are used to identify or track active. This replaces the older smear-microscopy diagnostic methodology. Professor Keertan Dheda from the University of Cape Town and the London School of Hygiene and Tropical Medicine joins me now live to tell us more about this.

A comparative study between two diagnostic interventions uncovers an improved active case finding strategy for TB

“Rapid treatment initiation remains the most effective way of rendering patients non-infectious. Thus, the XACT case finding strategy could be linked to new advances in TB treatment characterised by shortening of treatment regimens for both drug-sensitive and resistant TB”, said Dheda, PI.
