On Tuesday at the 5th Multilateral Initiative on Malaria (MIM) Pan-African Conference in Nairobi, Kenya, scientists and global health experts focused on malaria eradication, Agence France-Presse reports. “Key among the strategies … is the development of an effective anti-malaria vaccine, a project scientists have been researching since the late 80s. … RTS,S is the most clinically advanced malaria vaccine so far, according to the Malaria Vaccine Initiative,” the news service writes (11/3).

TIME reports on evidence along the Thai-Cambodia border that the malaria parasite is gaining resistance to artemisinin â€“ “the only remaining effective drug in the world’s arsenal against malaria’s most deadly strain.”
In a session at the 5th Multilateral Initiative on Malaria (MIM) Pan-African Conference in Nairobi, Kenya, experts discussed the tools required to eradicate the disease and highlighted insecticide and drug resistance in some parts of the world, Xinhua reports.
Noting that the “[r]oll-out of antiretroviral treatment for HIV in sub-Saharan Africa has been accompanied by rising rates of drug resistance,” Raph Hamers, a global health research fellow at the Academic Medical Centre of the University of Amsterdam, and colleagues “call for improved patient management and the integration of population-based drug resistance surveillance into national treatment programs” in this BMJ analysis. “In sub-Saharan Africa, the region with the highest HIV/AIDS burden, high-level political commitment and substantial international funding have led to an unparalleled scale-up of access to treatment over the past eight years,” they write, adding, “However, little attention has been paid to the potential emergence and spread of drug-resistant HIV and its public health implications.”
The Wall Street Journal reports on a rise of multi-drug resistant tuberculosis (TB) in India, writing, “India’s slow response to years of medical warnings now threatens to turn the country into an incubator for a mutant strain of tuberculosis that is proving resistant to all known treatments, raising alarms of a new global health hazard.” The newspaper continues, “Spread of the strain could return tuberculosis to the fatal plague that killed two-thirds of people afflicted, before modern treatments were developed in the 1940s, said Dr. Mario Raviglione, director of the Stop TB Department of the World Health Organization.” The newspaper notes, “The WHO is now assisting India to combat the strain” (Anand, 6/19).
In a study published on Wednesday in the Lancet, researchers from the Centers for Disease Control and Prevention found that “[a]mong 1,278 patients who were resistant to two or more first-line tuberculosis drugs in Estonia, Latvia, Peru, Philippines, Russia, South Africa, South Korea and Thailand, 43.7 percent showed resistance to at least one second-line drug,” which “suggest[s] the deadly disease may become ‘virtually untreatable,'” according to the study, Bloomberg Businessweek reports (Kitamura/Narayan, 8/29). “In about a fifth of cases, they found resistance to at least one second-line injectable [versus oral] drug,” according to Reuters, which states “[t]his ranged from two percent in the Philippines to 47 percent in Latvia.” Overall, 6.7 percent of patients had extensively drug-resistant TB (XDR-TB), meaning patients are resistant to the first-line drugs isoniazid and rifampicin as well as drugs in the fluoroquinolone antibiotic class and a second-line injectable antibiotic, Reuters adds, noting “[r]ates in South Korea, at 15.2 percent, and Russia at 11.3 percent, were more than twice the WHO’s global estimate of 5.4 percent at that time” (Kelland, 8/30).
The U.S. Government Accountability Office (GAO) recently released two reports on issues related to global health. In “Ensuring Drug Quality in Global Health Programs,” the agency writes, “Concerns have been raised about the potential for substandard drugs to enter the supply chains of global health programs,” and notes that it concluded, “U.S.-funded global health programs have put regulatory and policy requirements in place to help prevent procurement of substandard drugs” (8/1). In another report looking at the WHO, titled “Reform Agenda Developed, but U.S. Actions to Monitor Progress Could be Enhanced,” GAO found, “The United States has provided input into WHO’s reform agenda, particularly in the areas of transparency and accountability, but the Department of State’s (State) tool for assessing progress in the area of management reform could be enhanced” (7/23).
With incentives to find new antibiotics signed into U.S. law last month, “multiple players are vying for the lead in the [multi-drug resistant tuberculosis (MDR-TB)] drug development niche,” Nature Medicine reports. “The fifth reauthorization of the U.S. Prescription Drug User Fee Act (PDUFA), signed into law on 9 July, includes a subsection called the Generating Antibiotic Incentives Now (GAIN) Act that aims to spur development of antibiotics for drug-resistant bacteria, including MDR-TB,” the news service writes, noting, “Drug makers that ask for approval of medicines to treat these pathogens will receive priority review, as well as five additional years of market exclusivity and fast-track status.” Currently, MDR-TB treatment “involves a bevy of regular tuberculosis medicines that, in many cases, must be administered for as long as two years or more … [and] don’t always work,” Nature Medicine states, adding, “The hope is that new medicines will shorten treatment times and improve cure rates.” The article discusses several medicines that are in different phases of research (Willyard, 8/6).
“One in 10 cases of tuberculosis in China cannot be treated by the most commonly-used drugs, driven by a lack of testing and misuse of medicine, according to a national survey that showed for the first time the size of the drug-resistant epidemic,” the Associated Press reports (Wong, 6/7). “‘In 2007, one third of the patients with new cases of tuberculosis and one half of the patients with previously treated tuberculosis had drug-resistant disease,’ said the study in the New England Journal of Medicine,” Agence France-Presse reports, adding, “Even more, the prevalence of multi-drug resistant [tuberculosis (MDR-TB)] in new cases (5.7 percent) was nearly twice the global average, said the study” (6/6).
