Improving the Safety of Blood and Blood Related Products by Reducing the Risk of Transfusion-Transmission of Leishmania Parasites

Hira Nakhasi, PhD., FASTMH

Office of Blood Research and Review
Division of Emerging and Transfusion Transmitted Diseases
Laboratory of Emerging Pathogens



I am the Director of the Division of Emerging and Transfusion Transmitted Diseases in the Office of Blood Research and Review (OBRR) at the Center for Biologics Evaluation and Research (CBER) of FDA.  I received my Masters and Ph.D. in biochemistry from the M.S. University in Baroda, India and post-doctoral training at the National Institutes of Health in Bethesda, MD, USA and Columbia University in NY.   Before my current position, I was also the acting associate director for Research in OBRR/CBER and Chief of Laboratory of Parasitic Biology and Biochemistry in the Division of Allergenic and Parasitic Products, in the Office of Vaccines Research and Review at CBER.

My main research focus is on the development of Leishmania donovani vaccine and diagnosis. My laboratory is also developing diagnostic reagents for blood-borne parasitic pathogens to ensure the safety of our nation’s blood supply.

My scientific expertise in molecular virology, parasitology, immunology and vaccinology is reflected in over 130 publications, including reviews and book chapters and membership of the review committees of several high impact journals, reviewer of grants, and invited talks at national and international forums. My research on Leishmania vaccine is partially funded by research grants from various sources.  I am also a member of several scientific organizations, including the American Association of Immunologists, American Society of Microbiologists, American Society of Tropical Medicine and Hygiene, and a Fellow of the American Society of Tropical Medicine and Hygiene (FASTMH). I have also received numerous awards, including the US Department of Human and Health Services Distinguished Service Award.

General Overview

Leishmaniasis is a vector-borne disease caused by Leishmania parasites transmitted by the bite of certain species of sand fly in parts of South America, Africa, Southeast Asia, the Middle East, and Southern and Eastern Europe. It has been designated by the World Health Organization as one of the top 10 neglected tropical diseases. Environmental changes such as global warming or human migrations have affected the vector-reservoir-host triad and led an expansion of the leishmaniasis geographical range. Co-infection of HIV and visceral leishmaniasis has led to the reemergence of visceral leishmaniasis in Leishmania non-endemic countries.

United States military personnel or civilians stationed in areas of the world where leishmaniasis occurs are at risk of infection. This threat has increased in recent years because of extensive travel to these areas by US citizens and migration of people from endemic areas. Recently, it has been reported that local cases of Leishmania infection are occurring in the southern states of US.

Depending on the specific type of the disease, a person with leishmaniasis can develop disfiguring ulcers in the skin, nose, mouth, or throat; or suffer potentially fatal spleen or liver damage. Transfusions of blood from infected donors can also spread the parasite.

Approximately 12 million people are infected worldwide, > 350 million people at risk, with more than half a million new clinical cases reported annually and ~50,000 deaths annually. There are no vaccines or donor screening assays for Leishmania parasites. In addition, immigration from Latin American, Asian, African and Middle Eastern countries where incidence of Leishmaniasis is increasing because of the failure of health care system, non-compliance to drug treatment and political unrest in some of these countries poses a serious risk of spread of the disease in the US. 90% of human visceral leishmaniasis infections are asymptomatic and can transmit Leishmania parasite through blood transfusion. Industry is currently developing vaccines and diagnostic tests for Leishmania infection for evaluation by FDA.

One of the major obstacles to detecting the parasites in blood is that they occur in very low numbers. Therefore, we are developing methods using state-of-art technologies to solve that problem.

My laboratory is evaluating the safety and efficacy of various vaccine candidates, including genetically modified live attenuated parasites. We are also developing biomarkers of safety and immunity that can be used by the manufacturers to test the safety and effectiveness of such vaccines before submitting them to FDA for evaluation.

Scientific Overview

In addition, we have developed genetically modified Leishmania donovani parasites and performing preclinical evaluation of their immunogenicity and safety in animal models, such as mice, hamsters and dogs. We also are evaluating their immunogenicity in peripheral blood mononuclear cells form normal and infected individuals from the endemic regions of Leishmania.

Following are the specific regulatory challenges that my laboratory is trying to address regarding Leishmania vaccines.

  1. What are the differences in immune and non-immune biomarkers of immunogenicity among various Leishmania vaccine candidates (recombinant vs. genetically modified vaccines) and can some of the biomarkers predict protection in the clinical setting?
  2. Will Leishmania vaccines protect both lethal and non-lethal Leishmania infections?
  3. Will Leishmania vaccines protect in the presence of other co-parasitic infections, such as malaria and Chagas, which are common in the Leishmania endemic regions?
  4. Approximately 90% of the individuals who are infected with Leishmania do not show any symptoms. These individuals can transmit infections to non-infected individuals, either through blood transfusion or through the sand fly vector. Therefore, will Leishmania vaccine be effective in asymptomatic individuals?
  5. Natural infection in endemic areas occurs through the bite of an infected sand fly, which is the vector for Leishmania. Can Leishmania vaccines be effective against infection via sand fly bite in preclinical studies? 

To address the above-mentioned questions, we have accomplished some of the goals and are pursuing the others. These studies are being conducted in collaboration with scientists from with National Institute of Allergy and Infectious Diseases (NIH), Ohio State University, McGill University (Montreal, Canada) and the Institute of Tropical Medicine (Nagasaki University, Japan).
