How do people get infected with Leishmania parasites?
The main way is through the bite of infected female phlebotomine sand flies. Sand flies become infected by sucking blood from an infected animal or person. People might not realize that sand flies are present because:
-
They do not make any noise;
-
They are small: they are only about one third the size of typical mosquitoes or even smaller;
-
Their bites might not be noticed (the bites can be painless or painful).
Sand flies usually are most active in twilight, evening, and night-time hours (from dusk to dawn). Although sand flies are less active during the hottest time of the day, they may bite if they are disturbed (for example, if a person brushes up against the trunk of a tree or other site where sand flies are resting).
Some types (species) of Leishmania parasites also may be spread via contaminated needles (needle sharing) or blood transfusions. Congenital transmission (spread from a pregnant woman to her baby) has been reported.
Lifecycle in the sand fly
The sand fly feeds on blood from an infected mammal and takes up the amastigote form of the parasite into the abdominal midgut. Here the parasite transforms to the procyclic promastigote form. The parasite is then thought to attach to the midgut wall and finally migrate back towards the mouthparts. Just before it reaches the mouthparts it converts to its mammalian-infectious form, the metacyclic promastigote, ready for when the sand fly takes its next blood meal. The parasite is passed on because the sand fly regurgitates the mixture that lingers in its mouth parts into the bite before feeding.
What is Leishmaniasis?
Leishmaniasis is an important human and veterinary disease caused by Leishmania parasites that affect 12 million people in over 98 endemic countries. Leishmaniasis is a parasitic disease that is found in parts of the tropics, subtropics, and southern Europe. It is classified as a Neglected Tropical Disease (NTD). The disease is now emerging in Europe due to climate change and massive population displacement. The parasite is known to rapidly adapt to novel environments with important consequences for disease outcome. It has therefore been recognized as an emerging public health threat for the EU.
Leishmaniasis is caused by infection with Leishmania parasites, which are spread by the bite of phlebotomine sand flies. There are several different forms of leishmaniasis in people. The most common forms are:
-
cutaneous leishmaniasis, which causes skin sores,
-
mucosal leishmaniasis, which affect the nasal, oral and pharyngeal mucosa
-
and visceral leishmaniasis, which affects several internal organs (usually spleen, liver, and bone marrow).
Leishmaniasis is among the five most important parasitic diseases worldwide, with an estimated 350 million people at risk of infection. The disease causes a spectrum of clinical manifestations ranging from disfiguring cutaneous to fatal visceral forms, which results from infection by different species of Leishmania parasites. These unicellular parasites adapt to a remarkable range of hosts. They grow as extracellular parasites inside phlebotomine sand flies that transmit Leishmania to variety of vertebrates, such as rodents, dogs, and humans, where they grow inside immune cells, notably macrophages, causing severe pathologies that may lead to death.
Leishmaniasis is one of the most neglected diseases and as a consequence attracts limited attention. There is no human vaccine and only few treatments are available,.

What is IMPAVIDO (miltefosine)?
IMPAVIDO is a prescription medicine used to treat certain types of leishmaniasis:
-
visceral leishmaniasis (affecting your internal organs)
-
cutaneous leishmaniasis (affecting your skin)
-
mucosal leishmaniasis (affecting your nose, mouth and throat)
Impavido is the first and only FDA-approved drug to treat cutaneous or mucosal leishmaniasis, in addition to Viceral leishmaniasis.
It is not known if IMPAVIDO is safe and effective in children under 12 years of age.

On the left, an example of a vector sand fly (Phlebotomus papatasi) is shown; its blood meal is visible in its distended transparent abdomen. On the right, Leishmaniapromastigotes from a culture are shown. The flagellated promastigote stage of the parasite is found in sand flies and in cultures. Credit: PHIL, DPDx.
IMPAVIDO Drug Description
As of 2007, at least 1300 soldiers have been diagnosed with leishmaniasis (mostly CL but a few isolated cases of VL) since deployment to both countries; many speculate that the number may be as high as 2,500, due to underreporting or misdiagnoses by physicians unfamiliar with this exotic disease

Impavido® Higher Weight Patient Registry:
For patients who weigh 99 lbs or more, Impavido is administered at a dose of three (3) of the 50-mg capsules per day for 28 days.
Patients who weigh close to 99 lbs will receive more drug per pound than patients who have higher weights. For example, a patient who weighs 120 pounds will receive 1.25 mg of Impavido per pound each day [150 mg each day / 120 pounds = 1.25 mg per pound each day] whereas a patient who weighs 175 pounds will receive 0.86 mg of Impavido per pound each day [150 mg each day / 175 pounds = 0.86 mg per pound each day]. It is possible that Impavido will be less effective in higher-weight patients who receive less drug per pound than in lower-weight patients who receive more drug per pound.
If you weigh 165 pounds or more while taking Impavido (miltefosine), you are encouraged to enroll in The Higher Weight Registry by calling 1-866-588-5405
If you are exposed to Impavido (miltefosine) during pregnancy, contact your healthcare provider right away; you are also encouraged to enroll in the Pregnancy Registry by calling 1-866-588-5405
