“[T]he highest levels ever of drug-resistant tuberculosis (TB) have been found in Russia and Moldova,” the WHO reports in research published in the February edition of the WHO Bulletin, but “the agency didn’t have data from most of Africa and India, where tuberculosis rates are much higher,” the Associated Press/USA Today’s “Your Life” reports. According to the AP, the “experts reported that about 29 percent of new TB patients in parts of Russia were drug-resistant” and that “65 percent of previously treated patients in Moldova had resistance problems.” The news service notes, “Normally, less than five percent of TB cases are drug-resistant” (2/2).
This post in the Center for Strategic and International Studies’ “Smart Global Health” blog examines drug-resistant tuberculosis (TB), stating, “[S]ince the recent outbreak of the so-called totally drug-resistant tuberculosis (TDR-TB) in India, TB has a new face.” The blog details what TDR-TB is, recaps how resistant strains of TB develop and suggests several ways in which the global health community should respond (Kramer, 1/25).
This post in the Foreign Policy Association blog discusses reports from earlier this month of “an emerging strain of ‘totally drug-resistant’ tuberculosis (TDR-TB)” in India, which the Indian government last week denied, “arguing that the 12 cases were in fact extensively drug resistant (XDR).” The blog states, “Whether or not it’s fair to use the TDR moniker, drug resistance is a serious, emerging issue that may very well define the next stage of global health,” concluding, “We are reaching a turning point, one at which some drug resistant pathogens are on the cusp of shifting from a handful of cases, an endemic, to a bigger, epidemic or even pandemic problem. Now is the time to initiate discussions on what the global community will do to stem drug resistance” (Robinson, 1/21).
The Los Angeles Times’ “Booster Shots” blog features an interview with Otto Yang, a professor at the Geffen School of Medicine at UCLA, who speaks about drug-resistant tuberculosis (TB) and the implications of a highly drug-resistant strain found in India. Yang said, “Obviously [the drug-resistant TB] could be devastating if it spreads, because treatment options are so limited. So far it seems not to have been as contagious as other strains, possibly because the mutations required to make it drug-resistant also make it a little less virulent” (Brown, 1/18).
Health officials from India and the WHO are scheduled to meet in Mumbai on Tuesday to discuss how to manage the cases of at least 12 patients infected with a highly drug-resistant tuberculosis (TB) strain, Bloomberg reports (Narayan, 1/17). “The ‘totally drug-resistant’ tuberculosis (TDR-TB) reportedly emerging in India is actually an advanced stage of drug-resistant TB, which researchers called totally drug-resistant for lack of a better term,” IRIN notes (1/17).
Counterfeit, Substandard Drugs Threaten Progress In Controlling Malaria In Africa, Researchers Report
“Hopes of controlling malaria in Africa could be wrecked by criminals who are circulating counterfeit and substandard drugs, threatening millions of lives, scientists” said in a study published in the Malaria Journal last month, the Guardian reports. “They are calling for public health authorities to take urgent action to preserve the efficacy of the antimalarials now being used in the worst-hit areas of the continent,” the newspaper adds (Boseley, 1/16). “The counterfeit medicines could harm patients and promote drug resistance among malaria parasites, warns the study, funded by the Wellcome Trust,” BBC News writes (1/16).
“Malaria mortality rates have fallen by more than 25 percent globally since 2000, and by 33 percent in the WHO African Region, according to the World Malaria Report 2011, issued [Tuesday] by [the] WHO,” the organization reports in a press release. “This is the result of a significant scaling-up of malaria prevention and control measures in the last decade,” the press release adds. However, the press release notes, “WHO warns that a projected shortfall in funding threatens the fragile gains and that the double challenge of emerging drug and insecticide resistance needs to be proactively addressed” (12/13).
“Fake or poor quality malaria drugs are boosting resistance in parts of southeast Asia, a problem that is likely to worsen unless tighter regulations are adopted, U.S. experts said Monday” at a hearing of the House Foreign Affairs Subcommittee on Africa, Global Health, and Human Rights, Agence France-Presse reports. “‘Drug resistance to the most effective drug available, artemisinin-based combination therapy, is developing and has been recognized in southeast Asia,'” Regina Rabinovich, director of infectious diseases at the Bill & Melinda Gates Foundation, said, according to the news service.
Multi-drug resistant bacteria “are increasing their grip in Europe with rates of drug resistance in one type of bacteria reaching 50 percent in the worst-hit countries, health officials said Thursday,” Reuters reports. “In a report [.pdf] on multi-drug resistant bacteria, … the European Center for Disease Prevention and Control (ECDC), which monitors disease across the European Union, said the need to combat resistance was ‘critical,'” the news agency writes, adding, “To a large extent, antibiotic resistance is driven by the misuse and overuse of antibiotics, which encourages bacteria to develop new ways of overcoming them” (Kelland, 11/17).
“Europe’s health is suffering, with around 80,000 cases of tuberculosis infection a year and serious problems with measles, HIV and threats from ‘superbug’ infections, an annual health report” from the European Centre for Disease Prevention and Control (ECDC) said Thursday, Reuters reports. The report said infectious diseases and antibiotic resistance, especially multi-drug resistance, are major concerns, according to the news service. The “report also identified several emergent diseases in Europe it said might pose a risk to public health,” including West Nile virus, malaria, dengue fever and chikungunya, Reuters notes.
