BACKGROUND Pentavalent antimonials (SbV) are the first-line chemotherapy for American tegumentary leishmaniasis (ATL). There are, however, reports of the occurrence of treatment failure with these drugs. Few studies in Latin America have compared the response to SbV treatment in ATL caused by different Leishmania species. METHODS Clinical parameters and response to SbV chemotherapy were studi...
Visceral leishmaniasis (VL) is a vector-borne disease transmitted by phlebotomine sand flies and remains the most serious form of the disease with no available human vaccine. Repeatedly, studies have demonstrated the immunogenicity and protective efficacy of a number of sand fly salivary proteins against cutaneous and visceral leishmaniasis. All Leishmania species including agents of VL are co-...
Leishmaniasis - human immunodeficiency virus (HIV) coinfection can manifest itself as tegumentary or visceral leishmaniasis. Almost 35 countries have reported autochthonous coinfections. Visceral leishmaniasis is more frequently described. However, usual and unusual manifestations of tegumentary leishmaniasis have been reported mainly in the Americas, but the real prevalence of Leishmania infec...
BACKGROUND To describe an unusual clinical presentation of visceral leishmaniasis affecting the colon. CASE REPORT We report the case of an HIV-positive patient with visceral leishmaniasis. We describe the clinical case, the procedures performed, the treatment provided and the patient's evolution. A comparative table of previously reported similar cases is shown. DISCUSSION Visceral leishma...
Pentavalent antimonial (Sb) is the first treatment for cutaneous leishmaniasis (CL). Other drugs present similar side effects and higher cost. Oral miltefosine is effective to treat kala-azar. The aim of the present study was to compare the efficacy of glucamine (SbV) plus topical miltefosine with glucamine in the treatment of CL. Eighty isogenic C57BL/6 mice were inoculated with Leishmania (Le...
Leishmaniasis is a parasitic disease that primarily affects Asia, Africa, South America, and the Mediterranean basin. Despite extensive efforts to develop an effective prophylactic vaccine, no promising vaccine is available yet. However, recent advancements in computational vaccinology on the one hand and genome sequencing approaches on the other have generated new hopes in vaccine development....
Experimental vaccine candidates have been evaluated to prevent leishmaniasis, but no commercial vaccine has been proved to be effective against more than one parasite species. LiHyT is a Leishmania-specific protein that was firstly identified as protective against Leishmania infantum. In this study, LiHyT was evaluated as a vaccine to against two Leishmania species causing tegumentary leishmani...
Studies in the recent years have advanced the knowledge of how host and parasite factors contribute to the pathogenesis of human tegumentary leishmaniasis. Polymorphism within populations of Leishmania from the same species has been documented; indicating that infection with different strains may lead to distinct clinical pictures and can also interfere in the response to treatment. Moreover, d...
The control of zoonotic visceral leishmaniasis is a challenge, particularly in Brazil, where the disease has been gradually spreading across the country over the past 30 years. Strategies employed for decreasing the transmission risk are based on the control of vector populations and reservoirs; since humans are considered unnecessary for the maintenance of transmission. Among the adopted strat...
Visceral Leishmaniasis (VL), a systemic infection of the reticuloendotherlial system, is caused by a parasitic infection. The co-occurrence of VL and hemophagocytic syndrome (HPS) has been previously reported in several studies. In this report we present two cases of HPS and VL among members of the same family.
