Human leishmaniases in Morocco: a nosogeographical diversity

Abstract

Leishmaniases in Morocco are endemic diseases. Three forms of leishmaniasis are reported, visceral leishmaniasis, cutaneous leishmaniasis caused by Leishmania tropica and cutaneous lesions due to Leishmania major. Leishmania infantum, a common parasite inducing visceral leishmaniasis, was observed thereafter in cutaneous lesions. The first case of cutaneous leishmaniasis due to L. tropica was isolated since 1987. But, this parasite was shown to be more polymorphic with almost 8 zymodemes. However, these zymodemes are not all transmitted by Phlebotomus sergenti and not all isolated from human reservoir. Regarding the clinical aspect, cutaneous leishmaniasis with L. tropica is described as a single lesion starting as a nodule at the site of inoculation. A crust develops centrally which may fall away exposing an ulcer which heals gradually. The second cutaneous form is that caused by Leishmania major. It was known in villages located in the southern slopes of the Atlas Mountains. Clinically, the lesion is often severely inflamed and ulcerated and heals in 4-6 months. The epidemiologic cycle of this rural form, include Phlebotomus papatasi as the proven vector and a commensally rodent, Meriones shawi grandis as the reservoir. Howev...Continue Reading

Cardiac Cachexia

Cardiac cachexia is a syndrome associated with the progressive loss of muscle and fat mass. It most commonly affects patients with heart failure and can significantly decrease the quality of life and survival in these patients. Here is the latest research on cardiac cachexia.

Cachexia & Brown Fat

Cachexia is a condition associated with progressive weight loss due to severe illness. In cancer patients, it is proposed to occur as a result of tumor-induced energy wasting. Several proteins have been implicated in browning and depletion of white adipose tissue. Here is the latest research on cachexia and brown fat.
