Multidrug-resistant tuberculosis (MDR-TB) needs a proactive networked response particularly when it appears together with HIV infection, an international discussion on MDR-TB heard in Johannesburg on Monday.
”It is one disease where there are more questions than answers,” said Dr Norbert Ndjeka from Limpopo — part of a group of South African doctors who travelled to Latvia for training in MDR-TB management.
MDR-TB is TB which does not respond to standard treatment, and extreme drug-resistant TB (XDR-TB) is even more resistant to treatment. The combination of XDR-TB and HIV infection in South Africa has been proving deadly.
The Johannesburg meeting, organised by the international Lilly MDR-TB Partnership brought South Africans together with Lilly affiliates from Europe.
This partnership is underwritten by international pharmaceutical company Lilly to the tune of $70-million and brings together public and private partners, health professionals, business and communities to address MDR-TB around the world. It was the partnership’s first global study tour.
”Drugs are not enough,” said partnership project head, Dr Patrizia Carlevaro.
The partnership aims to combat the growing MDR-TB pandemic and support the World Health Organisation’s goal of treating 800 000 patients by 2015.
Ndjeka said 13 medical professionals from eight provinces — excluding the Eastern Cape — attended the Latvia training, which included monitoring and management, MDR-TB and HIV co-infection, infection control and drug management.
Ndjeka told the Johannesburg meeting that the training they received was ”superb” and said South Africa could learn a lot from Latvia’s management of MDR-TB.
”Their cure rate is above 66% … ours is below 50%.”
Ndjeka said Latvia had good methods of networking on patient difficulties.
”We do not have all the information around resistance patterns in the South African population.”
He said South Africa also did not have all the drugs — XDR-TB treatment required six or seven drugs.
Latvia has policies on infection control in place, runs effective isolation of XDR-TB patients, has masks and special lights to kill TB germs through radiation, and screens healthcare workers annually for infection.
The SA team trained in Latvia recommended to the health department that the national MDR-TB protocol be updated and encouraged research and networking on the MDR-TB problem, including HIV and TB collaboration.
”As government alone we cannot make it. Involvement of all stakeholders is essential to achieve better outcomes for our national TB control programme,” said Ndjeka.
”The growing incidence of extreme drug-resistant TB in South Africa is highlighting the urgent need for more effective measures for preventing, detecting, diagnosing and managing TB,” said Dr Kgosi Letlape, chairperson of the South African Medical Association (Sama).
Letlape said South Africa ranked seventh in the world in reported TB cases and was among the 22 high-burden countries targeted as part of the WHO’s Stop TB campaign.
He said Sama aimed to help develop the capacity of health professionals to deal with TB. He said TB and HIV care should be integrated and commented that HIV-positive patients were generally better informed than those with TB, which impacted on their treatment.
”You have got much higher compliancy among HIV patients than among TB patients.”
Sama is developing an online training course for physicians on MDR-TB which will include the WHO guidelines on combating the disease.
The course aims to provide doctors with the skills to diagnose, prevent, detect and manage TB, including promoting education and self-care, promoting therapy compliance and controlling associated disorders.
Letlape said 2 554 health professionals had been trained in TB management since 2003, and Sama hoped to increase this to 5 000 in 2007.
General secretary for the Democratic Nurses’ Association of South Africa (Denosa), Thembeka Gwagwa, said Denosa aimed to empower nurses to deal with TB.
As part of this, Denosa trained a core group of 20 nurses from seven provinces in TB management, who in turn trained another 500 nationally.
Northern Cape nurses reported that during the last quarter of 2006, after their 186 nurses were trained, the TB cure rate increased from 18,7% to 20,1%, while the treatment interruption rate dropped from 21,3% to 14,8%.
Eastern Cape trained 60 nurses, and reported that the TB treatment compliance improved by 30%.
Mpumalanga and KwaZulu-Natal nurses reported a ”sharp decrease” in the treatment interruption rate after training.
Gwagwa pointed out that some provinces had no budget for training, which ”doesn’t augur well”.
She said poverty was a huge challenge in battling MDR-TB, as it stopped patients from getting to clinics and meant they took medication on empty stomachs.
”MDR-TB is a man-made problem,” said nurse and educator Kathy Dennill, who heads the nursing leadership programme at the Foundation for Professional Development (FPD).
”It stems from bad management. And we need to look at that management.”
Dennill’s foundation runs training for nurses.
FPD’s Dr Anton Stoltz said the links between HIV and TB were crucial.
”It is very important that we know how people with TB present with HIV.”
In support of the battle against MDR-TB, Lilly has passed on the skills and technology needed to manufacture TB drugs.
”We have given away our trademark,” said Carlevaro.
”Twenty years ago people were saying MDR-TB is a lost cause. Now we say it’s cost-effective to treat.”
In South Africa, Lilly has passed on technology, skills and capital funding to pharmaceutical company Aspen Pharmacare, to enable it to produce low-cost drugs to fight MDR-TB, including XDR-TB.
Aspen currently manufactures the oral TB drug cycloserine and within about 15 months will be able to manufacture capreomycin, thanks to Lilly’s assistance, said Aspen executive director Stavros Nicolaou.
He said Aspen was developing the capacity to manufacture a dried injectible powder in a vial which required only water to be added to it, a method which kept the medicine stable. This would be used for capreomycin.
He urged support for the battle against both TB and HIV — ”a potentially devastating cocktail”.
Nicolaou said that thanks to Lilly’s help, Aspen could sell the MDR-TB drugs ”largely on a cost-recovery basis” instead of a profit-making basis. – Sapa
