Extra iron in red blood cells may interfere with essential proteins that protect against malaria, according to a new study published in Science. Researchers at the National Institutes of Health discovered extra iron can interfere with the protein ferroportin—a protein that prevents toxic buildup of iron in red blood cells and helps these cells combat malaria. More so, researchers discovered a mutation of ferroportin in African populations that protects against malaria by shielding against a hormone that prevents iron from being removed from the cells. These findings regarding ferroportin help solve a long-standing mystery as to why iron supplements can sometimes worsen malaria infection, while iron deficiency can in some cases be protective. A newly published study suggests children infected with the Zika virus during infancy may be at risk of experiencing brain damage. Researchers infected infant monkeys with the Zika virus, and the monkeys subsequently showed brain changes in the hippocampus—the part of the brain involved in regulating emotions, memory, and spatial navigation. After a year of study, researchers noticed the brains of the infected animals progressed differently than the monkeys who were not infected with Zika, suggesting damage and stunting. Though Zika has been linked to brain damage when it infects a fetus in the womb, this research is to first to link brain damage in infants to Zika infection after birth. While more research is needed into how the Zika virus can affect human babies, researchers believe this data may help inform new parents traveling to Zika-endemic areas and clinicians monitoring infants exposed to the virus. A new blood test is able to predict tuberculosis (TB) development up to two years before onset in individuals living with someone with active TB, according to new research. While individuals who live with someone with active TB are at higher risk of developing TB, only between 5-20 percent of people infected with the TB bacteria actually develop active TB, which means a large number of people are given preventative treatment who may not need it. By jointly measuring the expression levels of four different genes associated with inflammatory responses, this test can more accurately predict the likelihood of developing active TB. Researchers conducted a retrospective study with participants living in homes with people with active TB and found positive results of the blood test in the healthy participants who then later progressed to active TB. While more research is needed on the blood test, researchers are hopeful this test could reduce the number of individuals receiving unnecessary preventative treatments.  

Last Friday, President Donald Trump signed into law a US$1.3 trillion spending bill to fund the US government through the rest of fiscal year (FY) 2018. Reluctantly signed by the President among a flurry of “will he, won’t he” tweets, the legislation represents a forceful rebuke by Congress of the Administration’s proposal to drastically slash funding for global health and medical research programs. Key US agencies and programs that advance global health research and development (R&D) not only saw their funding protected in the spending bill, but many also saw increases. This outcome demonstrates that our community’s appeals and messages have not fallen on deaf ears and that Congressional policymakers on both sides of the aisle want to see the United States continue its leadership in advancing innovation to improve the health of those in need around the world. Here are some of the key takeaways from the 2,000+-page bill: US Agency for International Development & State Department While the Trump Administration proposed slashing funding for global health programs at the US Agency for International Development (USAID) and the State Department by 25 percent, Congress stood firm in protecting these programs. The bill ultimately sustained overall funding for these programs at FY17 enacted levels. A few programs received increases including a boost of $15 million for GAVI, the Vaccine Alliance; $20 million for tuberculosis (TB); and $15 million for maternal and child health. Funding for USAID HIV and AIDS programming and family planning at State and USAID, which the President proposed eliminating fully, was protected at FY17 levels. Congress also directed $135 million from repurposed Ebola emergency supplemental funding to support USAID’s global health security programs.   USAID plays a leading role in developing health technologies for low-resource settings through its various global health programs, so it is critical that these programs receive adequate funding, so they can continue to prioritize R&D among their other activities. In light of the President’s proposal for deep cuts to these programs, a combination of level funding for some programs and increases for others is a positive sign in the midst of a challenging budget environment. National Institutes of Health   Strong bipartisan support for the National Institutes of Health (NIH) continued for FY18. While the President proposed a 21 percent cut to NIH funding, the final spending bill instead provided the agency with an increase of $3 billion—8.8 percent—over FY17 levels. This represents a historic funding high for NIH in actual dollars with increases spread across various NIH institutes and programs. Notably, the National Institute of Allergy and Infectious Diseases received a 7.2 percent increase—39 percent above the President’s FY17 request—while the Fogarty International Center, which was targeted by the Administration for elimination, received a boost of 5.2 percent compared to FY17.   NIH is the world’s leading funder of R&D for neglected diseases, providing approximately 40 percent of total global funding, so any changes to its funding produce a ripple effect felt by global health research institutes and people around the world. It is encouraging to see Congress continue its record of bipartisan support for NIH and take action to strengthen our nation’s leadership in medical research. Centers for Disease Control and Prevention   The US Centers for Disease Control and Prevention (CDC) also received a plus up in the FY18 omnibus. The agency saw its funding increased by $1.1 billion—nearly 15 percent—over FY17 levels. This was in sharp contrast to the 16 percent cuts proposed by the Administration. The CDC Center for Global Health (CGH) received a 12 percent increase, compared to a 21 percent proposed cut. This included a $1.5 million boost for parasitic disease and malaria and a substantial increase of $50 million for global health security programming, which supports implementation of the Global Health Security Agenda (GHSA). Funding for global immunization and AIDS programming within CGH remained level. The National Center for Emerging and Zoonotic Infectious Diseases also received a more modest 5 percent increase over FY17 funding.   CDC plays a critical role in advancing technologies and improving health systems to better detect, prevent, and respond to infectious disease threats worldwide. There was much concern surrounding the FY18 budget for CDC as the agency is facing a funding cliff. CDC and USAID received $1 billion from the Ebola emergency supplement to fund GHSA, but this money is set to run out in 2019. As a result, the agency has already announced plans to scale back its GHSA work in 39 of 49 countries. While more funding is still needed to sustain these programs, and the agency has yet to clarify how it will adjust programming in light of its FY18 appropriations; it is promising to see Congressional appropriators recognize the value of CDC’s engagement in improving global health security. Biomedical Advanced Research and Development Authority   The Biomedical Advanced Research and Development Authority (BARDA), which develops medical countermeasures against health threats including emerging infectious diseases and antimicrobial resistance (AMR), also received a boost in the FY18 spending bill. The agency saw its funding increased by $25 million—about 5 percent—over FY17 levels.   BARDA has played an increasing role in R&D for naturally occurring threats and emerging infectious diseases in response to the Ebola and Zika epidemics. With its focus on bridging the “valley of death” in product development and its ability to use unique contracting mechanisms to forge innovative and long-term private-sector partnerships, BARDA is well positioned to make an impact in this space. However, the agency has been constrained by a lack of dedicated funding for its emerging infectious disease portfolio. While it is promising to see appropriators increase the agency’s overall funding for FY18, GHTC will be pushing for more dedicated funding for emerging infectious diseases in FY19. Department of Defense   The Department of Defense’s (DoD) activities in infectious disease research also saw increases in the omnibus. DoD’s Peer Reviewed Medical Research Program—a program that conducts research on AMR, diarrheal diseases, emerging infectious diseases, malaria, TB, and vaccine development for infectious diseases—received $330 million in funding, which is an increase of $30 million over FY17 levels.   The FY18 spending bill is a big win for global health R&D stakeholders and advocates, but this victory may only be temporary. The legislation funds the government through the end of September, and the Trump Administration has once against proposed drastic cuts to global health and medical-research programs for FY19. So while the ink dries on this year’s spending bill and we take a moment to celebrate, GHTC is already gearing up for another difficult battle ahead on next year’s budget.
