L. (L.) chagasi in AIDS and visceral leishmaniasis (kala-azar) co-infection.

چکیده
Concomitant skin lesions in visceral leishmaniasis (VL) or kala-azar are rare, being more common the description of post-kala-azar dermal leishmaniasis occurring post treatment of kala-azar. Skin lesions caused by Leishmania donovani are frequently seen in the aids-VL co-infection. In Brazil cutaneous or mucosal forms of tegumentary leishmaniasis concomitant with aids are more commonly registered. Here we present a case of aids-VL co-infection, with unusual cutaneous and digestive compromising attributed to L. (L.) chagasi, with special attention to ecthymatous aspect of the lesion, allied to the absence of parasite on the histological skin biopsy.

BACKGROUND & OBJECTIVES Kala-azar is the visceral and most severe form of leishmaniasis that leads to death if untreated. The causative agents of visceral leishmaniasis (VL) are members of Leishmania (L.) donovani complex which includes L. chagasi and L. infantum. Genome sequences have raised the question whether L. chagasi and L. infantum are synonymous or different. This question has importan...
متن کاملDNA polymorphism assay distinguishes isolates of Leishmania donovani that cause kala-azar from those that cause post-kala-azar dermal Leishmaniasis in humans.
Leishmania donovani in India causes visceral infection (kala-azar) and dermal infection (post-kala-azar dermal leishmaniasis). We report here the identification of polymorphism in a well-defined genetic locus among the Leishmania parasites causing the visceral and dermal manifestations, in a comparison of 15 post-kala-azar dermal leishmaniasis and 12 kala-azar patient isolates.
متن کاملLaboratory Diagnosis of Visceral Leishmaniasis
The group of diseases known as the leishmaniases are caused by obligate intracellular protozoa of the genus Leishmania (39). Natural transmission of leishmania is carried out by a certain species of sandfly of the genus Phlebotomus (Old World) or Lutzomyia (New World). These are present in three different forms: (i) visceral leishmaniasis (VL), (ii) cutaneous leishmaniasis, and (iii) mucocutane...
متن کاملPost-kala-azar dermal Leishmaniasis in two different clinical contexts*
In Brazil, visceral Leishmaniasis is caused by Leishmania chagasi. The development of cutaneous lesions in visceral leishmaniasis patients has been described in two different clinical contexts. Patients with compromised immunity can develop skin lesions as a direct consequence of a current visceral disease. Equally, patients with a history of kala-azar and progressive, immune improvement occasi...
متن کاملTherapeutic Options for Visceral Leishmaniasis
Visceral leishmaniasis (VL), also known as Kala-Azar, is a disseminated protozoal infection caused principally by Leishmania donovani and Leishmania infantum (known as Leishmania chagasi in South America). The therapeutic options for VL are diverse and depend on different factors, such as the geographical area of the infection, development of resistance to habitual treatments, HIV co-infection,...
