<br>About 11 million of 33 million HIV-positive people have TB, a Nobel laureate warns, and if financially troubled nations renege on aid pledges, it would deprive the poor of treatment.<br><br>Mary Engel, Los Angeles Times Staff Writer<br>
<br>Fearing that the global economic crisis could cause nations to renege on commitments to fight tuberculosis, new Nobel laureate and HIV co-discoverer Francoise Barre-Sinoussi warned that a drop in TB funding could wipe out gains made against AIDS because so many people suffer from both diseases.<br>
<br>"We are at the period of success with antiretroviral treatment" for HIV, Barre-Sinoussi said Tuesday during a teleconference from the Pasteur Institute in Paris. "But we have an epidemic of multi-resistance to tuberculosis treatment, which is really alarming."<br>
<br>An estimated 33 million people worldwide are infected with HIV. About 11 million of them also have tuberculosis, Barre-Sinoussi said. By suppressing the immune system, HIV leaves people susceptible to other infections, including TB.<br>
<br>In sub-Saharan Africa, where HIV infects more than 22 million people, TB incidence has quadrupled in the last 15 years, Chaisson said.<br><br>Nonresistant TB is curable, but the majority of Africans are not getting antibiotics, according to the World Health Organization. And a dangerous form of the disease, multidrug- resistant TB, now accounts for 5% of all new TB cases worldwide, and 15% to 22% of new cases in parts of the former Soviet Union and China.<br>
<br>Even the drug-resistant strain is treatable with the right antibiotics. But for a rarer and even more dangerous strain known as extensively drug-resistant TB, half of those treated don't survive, Chaisson said.<br>
<br>International funding is used to provide treatment in poor countries as well as for research on new antibiotics.<br><br>What concerns Barre-Sinoussi is that neither HIV nor TB was discussed at the summit of the Group of 8 leading industrialized nations in Japan in July. And that was before the economic situation worsened in recent weeks.<br>
