Leishmaniose cutanée : un important problèmede santé
La leishmaniose cutanée est une maladie potentiellement grave et défigurante. Les personnes atteintes de leishmaniose cutanée ont une ou plusieurs lésions durables sur la peau, le plus souvent sans fièvre ni symptômes généraux. L'impac...t de la leishmaniose cutanée sur la propagation de la pauvreté est important, car le traitement est coûteux et donc inabordable ou implique une grande perte d’argent.
Le coût du traitement et de la mise en œuvre de stratégies de prévention nécessite un investissement considérable de ressources financières et humaines. La leishmaniose cutanée est un problème de santé publique majeur dans la Région de l'OMS pour la Méditerranée orientale. Des nouveaux cas apparaissent dans des zones précédemment indemnes de la maladie. Plus de 100 000 nouveaux cas de leishmaniose cutanée sont notifiés chaque année à l'OMS par les pays de la Région, mais les estimations relatives à l'incidence réelle sont de trois à cinq fois plus élevées car de nombreux patients ne consultent jamais un médecin ou un professionnel de santé et les cas ayant reçu un diagnostic de leishmaniose cutanée ne sont pas toujours notifiés aux autorités sanitaires.

Stopleishmania.org is an initiative of the VISAVET Health Surveillance Centre (UCM), the National Centre of Microbiology (ISCIII), the Animal Protection Centre (Madrid City Council) and the Directorate of Public Health (Regional Government of Madrid). This proj...ect launches the possibility of collaboration with other research centres, feeding the site with updated information on this disease.
Leishmaniosis prevention and control should include novel communication strategies that must be easily accesible and would include new advances in the knowledge of the disease. Recently, other animals different than dogs have been described as competent reservoirs of Leishmania, playing an important epidemiological role in recent outbreaks in Europe and Asia. At the moment, most of the information available is fundamentally devoted to humans and dogs, and there is no a global approach to the disease, taking into account all possible reservoirs.
The contents are available in Spanish and English, and come from the knowledge and experience in the disease of the above mentioned organisms, including research and information outreach.
The result is a website mainly focused on dissemination of the fundamental aspects for the control and prevention of the disease, taking into account that leishmaniosis due to its zoonotic condition, requires a multidisciplinary vision in accordance with the "One Health" principles. The web is complemented by a collaborative tool where the registered research groups can present themselves and disseminate their research results, therefore providing updated information on the scientific advances in the disease control.

In the Region of the Americas, the leishmaniases are a group of diseases caused by various species of Leishmania, which cause a set of clinical syndromes in infected humans that can involve the skin, mucosa, and visceral organs. The spectrum of clinical disease is varied and depends on the interacti...on of several factors related to the parasite, the vector, and the host. Cutaneous leishmaniasis is the form most frequently reported in the Region and nearly 90% of cases present single or multiple localized lesions. Other cutaneous clinical forms, such as disseminated and diffuse cutaneous leishmaniasis, are more difficult to treat and relapses are common. The mucosal form is serious because it can cause disfigurement and severe disability if not diagnosed and treated early on. Visceral leishmaniasis is the most severe form, as it can cause death in up to 90% of untreated people.

Frequently Asked Questions on Visceral Leishmaniasis
Cutaneous leishmaniasis (CL) is a neglected infectious endemic disease that is transmitted through the bite of a vector insect (sandfly) of the Lutzomyia genus,typical of rural geographical territories, and causes disfiguring skin ulcers and disabilities. It is estimated that CL affects between 600 ...000 and 1 000 000 people a year around the world, mainly in the America s, the Mediterranean basin, the Middle East and Central Asia. Eighteen of the 21 countries that make up the Latin American (LA) region are considered endemic areas for this neglected tropical disease. Colombia is one of the countries that reports the majority of global cases with 6161 in 2020 and has the second highest number of cases in the Americas, after Brazil.

The leishmaniases are a group of diseases caused by Leishmania spp., which occur in cutaneous, mucocutaneous and visceral forms. They are neglected tropical diseases (NTDs), which disproportionately affect marginalized populations who have limited access to health care. HIV co-infected patients with... Leishmania infection are highly infectious to sandflies, and an increase in the coinfection rate in an endemic area is likely to increase the effective infective reservoir.

2nd edition. These guidelines include several notable changes from the first edition. For cutaneous leishmaniasis, ketoconazole has been removed from the list of treatment options; the number of Leishmania species for which there is strong evidence for the efficacy of miltefosine has increased from ...two to four; and the recommendation for intralesional antimonials is now strong. For mucosal leishmaniasis there is now a strong recommendation for use of pentavalent antimonials with or without oral pentoxifylline. For visceral leishmaniasis, the strong recommendations for use of pentavalent antimonials and amphotericin B deoxycholate are now conditional.

This publication represents a key step forward in translating Control of the leishmaniases (WHO Technical Report Series, No. 949) into a more practical tool for health personnel directly involved in the case management of cutaneous leishmaniasis. With this manual, countries will have, for the first ...time, standardized diagnosis and treatment protocols, case definitions and indicators to enable them to easily track progress on cutaneous leishmaniasis case management across the Region. It will provide support to professionals in charge of cutaneous leishmaniasis, in order to alleviate the suffering of affected populations from this appalling disfiguring and stigmatizing neglected tropical disease.

Leishmaniasis is a vector-borne disease that is transmitted by sandflies and caused by obligate intracellular protozoa of the genus Leishmania. Human infection is caused by about 21 of 30 species that infect mammals. These include the L. donovani complex with 3 species (L. donovani, L. infantum, and... L. chagasi); the L. mexicana complex with 3 main species (L. mexicana, L. amazonensis, and L. venezuelensis); L. tropica; L. major; L. aethiopica; and the subgenus Viannia with 4 main species (L. (V.) braziliensis, L. (V.) guyanensis, L. (V.) panamensis, and L. (V.) peruviana). The different species are morphologically indistinguishable, but they can be differentiated by isoenzyme analysis, molecular methods, or monoclonal antibodies.
