Her mother grimaces as she tries to reassure her, but the tremble in her voice doesn’€™t hide her own terror at seeing her little one in such distress. The doctor and nurses turn the child on her side in case she vomits.

Zodwa Dlamini* (27) is still in a state of shock. A week earlier she had taken Busi* (5) to the clinic. The mother had tried to suppress the nagging voice in her head, but she knew the classic symptoms too well ‘€“ night sweats, weight loss, coughing ‘€“ symptoms she had been confronted with herself barely two years earlier when she had been told she had TB and which were now manifesting in her little one.

Before the Durban mother had time to process it all, her child was on TB treatment, which equated to taking a handful of huge, unpalatable tablets every day.

This morning they found themselves back at their local hospital in an attempt to get sputum from the little one’€™s stomach.

The sputum will then be tested in the hope of excluding drug-resistant TB, a diagnosis which would mean a long spell in hospital, painful injections, more drugs and no guarantee of a cure.

Saturday is World TB Day and this year’€™s theme is Our goal: No TB deaths for children.

According to statistics from The International Union against TB and Lung Disease (The Union), an estimated one million children 14 years and under will need TB treatment this year ‘€” and some experts claim the number is much higher.

Two hundred children die from TB every day. Yet it costs less than 3 cents a day to provide therapy that will prevent children from becoming ill with TB and 50 cents a day to provide treatment that will cure the disease.

TB in children is typically under-detected and under-reported, reflecting its low priority on the public health agenda.

 “Historically, TB control efforts have not focused on children because the majority are smear-negative and therefore not a major source of infection”, says Dr Steve Graham of the Child Lung Health Division of The Union. “With limited resources, the focus was put where it seemed most critical ‘€” on adults with smear-positive TB”.

Infants and young children are more likely to develop TB that disseminates throughout the body and TB meningitis, both of which carry a high risk of death and disability. Children who are HIV-infected additionally face a 20-fold greater risk of developing TB than uninfected children, and a 5-fold greater risk of death.

Dr Mario Raviglione, Director of the WHO Stop TB Department agrees that despite the gains in addressing the adult TB epidemic, to a large extent, children have been left behind, and childhood TB remains a hidden epidemic in most countries.

Professor Robert Gie of the Department of Paediatrics and Child Health at the University of Stellenbosch, agrees that TB in children has been neglected for years and that it is only relatively recently that some attention is being paid to how this disease affects children.

‘€œTuberculosis is politics and it’€™s the politics of poverty and the struggle now is to get countries to look after their children,’€ says Gie.

‘€œThis policy to only treat the adults and ignore the children had a disastrous effect,’€ said Gie, who until recently chaired a WHO sub-group for children.

For years there was no research done into paediatric TB which meant no diagnostic tests and no drugs adapted into child-friendly tablets.

 ‘€œWe think that only about half of children with TB are accessing care,’€ said Gie.

He says that there have been positive developments with a drive for child-friendly diagnostics, a better understanding of the dosages needed to effectively treat children and the possibility of a lighter pill burden on the horizon.

‘€œChildren are the consequence of the epidemic. The first group that will show you whether you are controlling the TB epidemic, will be the children,’€ Gie adds.

Gie cautions that despite the advancements, he is yet to see any countries outside of the United States and some in Europe ‘€“ and he has visited more than 50 countries ‘€“ that have successfully prevented TB in children.

‘€œWe know it boils down to contact screening and management, but nobody does it. It’€™s not sexy and health care providers at clinic level don’€™t think it’€™s necessary. Basically they do the maths and know that they need to treat 100 children to prevent one case of adult TB, so they just don’€™t see the advantage,’€ says Gie.

Dr James Seddon, visiting researcher at the Desmond Tutu TB Centre has been investigating the treatment of drug-resistant TB in children. ‘€œWe are just rubbish at finding those children who have been exposed to TB and either treating them or making sure we prevent them from developing disease.’€

In terms of treating drug-resistant TB, Seddon said the options available for children were ‘€œdisastrous’€.

‘€œWe have nothing specifically for children, so we are really figuring out how much to give and how to break and divide the tablets to give the children the correct dosages. Even then, we are not completely sure what level of medication in the blood is needed to ensure we will kill the bugs,’€ says Seddon.

To cure drug-resistant TB a child is mostly hospitalised in order to receive multiple drugs including some that require to be given by injection. The drugs are old with severe side-effects and there are not many clinicians with the know-how to treat these children.

‘€œChildren really need to be a priority, they deserve better. It really has been a case of dealing with everything else first and then the children,’€ says Seddon.

South Africa has a high burden of TB. The latest statistics are from 2010.

TB prevalence                                                                                  400 per 1 000 population

TB incidence (new cases)                                         490 per 1 000

1,8% of new TB cases are multi-drug resistant

128 457 (60%) TB patients were HIV positive

TB is among the three greatest causes of death among women 15 to 44 worldwide.

There were 9,4-million new TB cases in 2009, including 1,1-million cases among people living with HIV.
