NIAID Raises Awareness to Malaria-like Diseases in W. Africa

Dengue, Zika, Chikungunya Viruses in Mali; Disease Likely Misdiagnosed

NIAID scientists and colleagues have identified dengue, Zika and chikungunya viruses in the West African country of Mali, where health care providers likely misdiagnose patients with illness from those viruses due to unavailable diagnostic tools. Because malaria is the most common fever-causing illness in rural sub-Saharan Africa, most medical workers presume patients with a fever have malaria. The primary cause of all four infectious diseases is a mosquito bite.

Records from the Malian Health Information System show that about one-third of all patient visits to health care facilities are related to malaria, with 2.37 million clinical cases.

A new study from NIAID’s Rocky Mountain Laboratories and the University of Sciences, Techniques and Technologies in Mali aims to help spread information to medical workers about the existence of the additional viral diseases. Ideally, circulating the information will help them obtain the necessary diagnostics.

The study, published in The American Journal of Tropical Medicine and Hygiene, involved 600 residents, 200 from each of the southern Malian communities of Soromba, Bamba and Banzana. The scientists detected antibodies to dengue virus in the blood of 77.2% of the residents tested; to Zika virus in 31.2%, and to chikungunya virus in 25.8%. They detected at least one of the three viruses in 84.9% of participants, meaning just 15.1% tested negative to any of the three viruses.

Evidence of the parasites that cause malaria was found in 44.5% of those tested. Unlike malaria, however, where most cases are found in children under age 14, residents over age 50 were most likely to have been exposed to dengue, Zika or chikungunya viruses. 

“Despite the high exposure risk to dengue virus in southern Mali, dengue fever cases have rarely been reported,” the researchers write. “This is likely due to the lack of diagnostic testing and the biased clinical focus on malaria in the region. Awareness of dengue virus as a cause of febrile illness needs to be urgently established in medical communities as an important public health measure.”

The scientists are hoping data from a more in-depth clinical study that just ended will provide additional details about the prevalence of these viruses in Mali. They also are planning to examine patients who have undiagnosed fevers to establish infection rates.

NIAID scientists are investigating dengue, Zika and chikungunya viruses to try and develop preventive and therapeutic treatment options, none of which exist.

The HIV Field Needs Early-Stage Investigators (VIDEO)

NIAID Now |

by Jeanne Marrazzo, M.D., M.P.H., NIAID Director

The HIV research community is led by scientists with deep personal commitments to improving the lives of people with and affected by HIV. Some researchers, like me, have pursued this cause since the start of the HIV pandemic, growing our careers studying HIV from basic to implementation science. Our collective decades of work have generated HIV testing, prevention and treatment options beyond what we could have imagined in the 1980s. Those advances enable NIAID to explore new frontiers: expanding HIV prevention and treatment modalities, increasing understanding of the interplay between HIV and other infectious and non-communicable diseases, optimizing choice and convenience, and building on the ever-growing knowledge base that we need to develop a preventive vaccine and cure. The next generation of leaders will bring these concepts to fruition, and we need to welcome and support them into the complex and competitive field of HIV science.

Click below for a video in which NIAID grantees and I discuss the value and experience of early-stage HIV investigators (the audio described version is here):

NIAID wants to fund more new HIV scientists and we have special programs and funding approaches to meet that goal. This week, the NIH Office of AIDS Research will host a virtual workshop on early-career HIV investigators tomorrow, April 24, and NIAID will host its next grant writing Webinars in MayJune, and July.

Researchers Create Safer Form of Coxiella burnetii for Scientific Use

Scientists have unexpectedly discovered that the weakened form of the bacteria Coxiella burnetii (C. burnetii) not typically known to cause disease, naturally acquired an ability to do so. C. burnetii causes Q Fever in humans and its weakened forms are those used for scientific purposes. Subsequently, the scientists identified the genetic mutation responsible for the increased ability to cause disease (virulence) and created a form of the bacteria without the genetic flaw that could safely be used for research.

Apply to Create a Diagnostic Center of Excellence for the Undiagnosed Diseases Network

Funding News Editions:
See more articles in this edition

Consider applying to the notice of funding opportunity (NOFO): Diagnostic Centers of Excellence for the Undiagnosed Diseases Network (U01, Clinical Trial Not Allowed) if you can establish a clinical site to provide an expert Diagnostic Centers of Excellence (DCoE) for undiagnosed diseases.

Undiagnosed diseases can present physical, emotional, and financial burdens to patients, families, and care teams who may spend years seeking a diagnosis and a path to treatment. In 2008, NIH established an intramural Undiagnosed Diseases Program (UDP) to aid individuals plagued by longstanding medical conditions that elude medical diagnosis. The UDP was successful in ending the “diagnostic odyssey” for individuals with undiagnosed, rare, challenging diseases. In 2012, the NIH Common Fund announced the expansion of the UDP to form a nation-wide network, the Undiagnosed Diseases Network (UDN), composed of the NIH UDP and extramural clinical sites.

Research Objectives

This NOFO leverages multiple NIH institutes and centers (ICs), including NIAID, to seek proposals from highly qualified clinical sites in the United States to join the Phase III Network as DCoEs through cooperative agreement awards. Awarded DCoEs will have access to Data Management and Coordinating Center (DMCC) resources and infrastructure including high-quality phenotypic and genotypic data and collaboration with highly skilled physicians, researchers, and bioinformaticians. Successful applicants will demonstrate that they have the appropriate expertise, resources, and infrastructure needed to conduct advanced diagnostic evaluations at their site and propose a research plan that meets some of the following Phase III Priorities.

Read the NOFO linked above for the full list of priorities:

  1. Scale clinical capacity to engage more applicants across the United States by increasing diagnostic efficiencies and incorporating community and third-party payer support for patient services. DCoEs should do the following:

    Provide a plan to enroll an achievable number of participants based on the site’s experience, outreach capabilities, community needs, and budget. Awarded DCoEs are expected to work with the DMCC to develop an enrollment plan that utilizes a tiered evaluation approach and is based on the specific diagnostic needs of each participant with plans to scale up enrollment as diagnostic efficiencies are established.

    Work closely with the DMCC and other DCoEs to improve the efficiency and cost-effectiveness of the clinical evaluation (e.g., artificial intelligence (AI)/machine learning and other innovative tools for record review and data analysis, tiered evaluation strategies and remote visits as described above), while still providing a comprehensive and expeditious clinical evaluation of participants.

    Although DCoEs are encouraged to enroll and evaluate participants with disorders in any clinical specialty, applicants have the option to specialize in one or more areas of clinical practice, including but not limited to pediatrics, neurology, ophthalmology, cardiology, gastroenterology, immunology, metabolism, and environmentally linked or infectious diseases.

  1. Expand access to the UDN for individuals and groups who historically have not benefited from modern diagnostic investigations due to race, ethnicity, socioeconomic status, geographic location, sex/gender, linguistic, or other systemic barriers. DCoEs should do the following to achieve this goal:

    Collaborate with the DMCC to recruit and enroll individuals from U.S. populations that experience health disparities.

    Partner with community collaborators that serve populations that experience health disparities, including but not limited to academic institutions, local healthcare systems and hospitals, and state and local public health agencies. At least one of the partnerships must be a community healthcare organization that provides services for economically disadvantaged individuals who are under/uninsured.

  1. In addition to continuing the fruitful genomic approaches established in Phase I/II of the UDN, Phase III DCoEs are expected to propose and develop innovative strategies to investigate other potential causal factors in undiagnosed diseases such as environmental insults, infectious, oncologic, immunologic, or complex genetic disorders.
  2. Ensure that participants consistently receive a high-quality experience, for example, by collaborating with the DMCC to survey and incorporate input from patients, caregivers, and family members into the practice of the UDN.

Applicants should include external sources of support within their application and describe existing or planned resources available to them, along with an overview of how they will leverage these resources to cover the patient costs and diagnostic testing of UDN participants at the site.

Additionally, applicants need to seek reimbursement from outside funding sources for patient services and routine diagnostic testing (e.g., by billing insurance, utilizing support from their institutions, outside partnerships, state and federal grants, philanthropic organizations, foundations, or private donors).

Notably, this NOFO requires a Plan for Enhancing Diverse Perspectives (PEDP) as part of the application. Applicants should read the instructions carefully and view the available PEDP Guidance Material since they must include a PEDP as an attachment as part of Other Project Information.

NIH will assess the PEDP as part of the scientific and technical peer review evaluation, as well as consider among programmatic matters with respect to funding decisions. The National Institute of Neurological Disorders and Stroke (NINDS) will consider applications that propose clinical trials or do not include a PEDP to be nonresponsive and not review them.

Award and Contact Information

The maximum project period is 4 years, and your application budget may not exceed $500,000 in annual direct costs. The budget must reflect the actual needs of the proposed project. Note that budgets may be administratively reduced before award based on program priorities and the amount of NIH appropriations.

Applications are due on November 3, 2023, by 5 p.m. local time of the applicant organization.

If you have inquiries about this NOFO, contact NIAID’s scientific/research contact, Dr. Stacy Ferguson at fergusonst@niaid.nih.gov or 240-627-3504. NINDS will coordinate peer review for this NOFO; for review-related questions, email nindsreview.nih.gov@mail.nih.gov.

Hepatitis B and C—A Closer Look at NIAID Research to Accelerate Elimination

NIAID Now |

Viral hepatitis is an inflammatory liver disease caused by infection with any of the known hepatitis viruses—A, B, C, D, and E. Most of the global viral hepatitis burden is from hepatitis B and C, which affect 354 million people and result in 1.1 million deaths annually. The Centers for Disease Control and Prevention estimates that in 2020 there were 14,000 and 50,300 new acute infections of hepatitis B and C in the United States, respectively, while at least 880,000 people in the country were living with chronic (long-term) hepatitis B and 2.4 million people had chronic hepatitis C. About half of those with viral hepatitis are unaware of their infection. Chronic and persistent inflammation from the disease can lead to liver failure, cirrhosis, or liver cancer. Viral hepatitis affects all ages and there are pronounced inequities in disease outcomes in the United States. Hepatitis B and C disproportionately affect people living with HIV, and HIV increases the rate of complications and death in people with viral hepatitis.

On this World Hepatitis Day, the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, shares a snapshot of its investments in basic (laboratory), preclinical (laboratory/animal), and clinical (human) research to improve screening, prevention and treatment for hepatitis B and C. Scientists in the Hepatic Pathogenesis and Structural Virology sections of NIAID’s Laboratory of Infectious Diseases conduct basic and translational research to better understand hepatitis B and C disease progression, clarify the role of hepatitis viruses in liver cancer, and inform discovery of new vaccines, medicine and technologies. Both NIAID’s Division of AIDS (DAIDS) and the Division of Microbiology and Infectious Disease (DMID) support scientific programs focused on hepatitis B and C research and curative strategies, reflecting the widespread impact of viral hepatitis and the urgent need for safe and effective interventions.

Finding a hepatitis B cure

Hepatitis B continues to cause disease and death even though a highly effective preventive vaccine has been available for decades. Some people with acute hepatitis B can naturally clear the infection. In others, chronic HBV requires lifelong treatment to suppress the virus. More research is need to identify novel therapeutic options and strategies to minimize the treatment burden and, ideally, identify a cure for hepatitis B. NIAID is supporting research on a variety of basic, translational and therapeutic science concepts designed to cure hepatitis B, including in people with HIV. DMID recently announced an initiative to develop new antiviral drugs that can eliminate hepatitis B genetic material from infected cells, and DAIDS is complementing that work with clinical studies of therapeutic agents and vaccines that will include evaluation of their safety and efficacy in people living with HIV.

Streamlining the hepatitis C response

In 2011, direct-acting antivirals (DAA) revolutionized hepatitis C therapy and have since been observed to cure 95% of cases. Despite DAA availability for more than a decade, only one in three people in the United States diagnosed with hepatitis C receive curative treatment. These circumstances underscore the importance of increasing access to and convenience of diagnosis and treatment, as well as the need for a preventive vaccine. Developing a hepatitis C vaccine is challenging because of the genetic diversity of hepatitis C circulating in the population, necessitating broadly reactive vaccine technology. DMID awarded multiple grants to advance new hepatitis C vaccine designs in 2021. To better enable people to know their hepatitis C status, NIAID and other NIH institutes are supporting discovery of improved point-of-care hepatitis C testing that could be used in community and healthcare settings alike, and eliminate the need to wait for laboratory-based diagnostics. They are also supporting development of self-testing technology that people can use to screen themselves. DAIDS will soon launch an initiative to develop long-acting DAAs that could reduce the number of doses required for a full course of therapy. A recent NIAID-supported study showed even with an existing 84-tablet DAA regimen, most people with hepatitis C experienced favorable treatment outcomes without in-person healthcare visits for the duration of treatment. These innovations in diagnostics and treatment strategies aim to enable a “single-encounter cure” wherein a person could learn their hepatitis C status and collect their treatment in one healthcare visit.

These research priorities are among the current efforts in NIAID’s 60-year pursuit of scientific advances to improve the health outcomes of people with viral hepatitis. For more information on US government research to help eliminate viral hepatitis, please visit:
