The treatment is determined by where the disease is acquired, the species of Leishmania, and the type of infection. [2] For visceral leishmaniasis in India, South America, and the Mediterranean, liposomal amphotericin B is the recommended treatment and is often used as a single dose. [3] [9] Rates of cure with a single dose of amphotericin have ...
Visceral leishmaniasis (VL), also known as kala-azar (Hindi: kālā āzār, "black sickness") [2] or "black fever", is the most severe form of leishmaniasis and, without proper diagnosis and treatment, is associated with high fatality. [3] Leishmaniasis is a disease caused by protozoan parasites of the genus Leishmania.
Leishmania / l iː ʃ ˈ m eɪ n i ə,-ˈ m æ n-/ [1] is a parasitic protozoan, a single-celled organism of the genus Leishmania that is responsible for the disease leishmaniasis. [2] [3] [4] They are spread by sandflies of the genus Phlebotomus in the Old World, and of the genus Lutzomyia in the New World.
Leishmania braziliensis, like other species of Leishmania, rely on asexual reproduction in the intermediate mammalian host to greatly increase population density. Such reproduction is often witnessed in mononuclear phagocytes (dendritic cells, monocytes, neutrophils) of the mammalian host, with the macrophages being the target white blood cell of the parasite.

This type does not produce ulcers and there is no treatment. Treatment of Leishmaniasis caused by L. mexicana consists of pentavalent antimonials as Pentostam or Glucantime injected direct into the ulcer or Intramuscular. Prevention of L. mexicana infection is principally avoiding the bite of the infected sandfly.
Sodium stibogluconate, sold under the brand name Pentostam among others, is a medication used to treat leishmaniasis. [3] This includes leishmaniasis of the cutaneous, visceral, and mucosal types. [4] Some combination of miltefosine, paromomycin and liposomal amphotericin B, however, may be recommended due to issues with resistance.
