    Bob Champion Research & Education Building, Norwich Medical School, University of East Anglia, Norwich Research Park, James Watson Road, Norwich, NR4 7UQ, UK.
    In this review article the history of leishmaniasis is discussed regarding the origin of the genus Leishmania in the Mesozoic era and its subsequent geographical distribution, initial evidence of the disease in ancient times, first accounts of the infection in the Middle Ages, and the discovery of Leishmania parasites as causative agents of leishmaniasis in modern times. With respect to the origin and dispersal of Leishmania parasites, the three currently debated hypotheses (Palaearctic, Neotropical and supercontinental origin, respectively) are presented. Ancient documents and paleoparasitological data indicate that leishmaniasis was already widespread in antiquity. Read More

    CD8+ T cell cytotoxicity mediates pathology in the skin by inflammasome activation and IL-1β production.
    PLoS Pathog 2017 Feb 13;13(2):e1006196. Epub 2017 Feb 13.
    Department of Pathobiology, School of Veterinary Medicine, University of Pennsylvania, Philadelphia, Pennsylvania, United States of America.
    Deregulated CD8+ T cell cytotoxicity plays a central role in enhancing disease severity in several conditions. However, we have little understanding of the mechanisms by which immunopathology develops as a consequence of cytotoxicity. Using murine models of inflammation induced by the protozoan parasite leishmania, and data obtained from patients with cutaneous leishmaniasis, we uncovered a previously unrecognized role for NLRP3 inflammasome activation and IL-1β release as a detrimental consequence of CD8+ T cell-mediated cytotoxicity, ultimately resulting in chronic inflammation.

    Department of Microbiology, Calcutta School of Tropical Medicine, Kolkata, West Bengal, India.
    Asymptomatic leishmaniasis may drive the epidemic and an important challenge to reach the goal of joint Visceral Leishmaniasis (VL) elimination initiative taken by three Asian countries. The role of these asymptomatic carriers in disease transmission, prognosis at individual level and rate of transformation to symptomatic VL/Post Kala-azar Dermal Leishmaniasis (PKDL) needs to be evaluated. Asymptomatic cases were diagnosed by active mass survey in eight tribal villages by detecting antileishmanial antibody using rK39 based rapid diagnostic kits and followed up for three years to observe the pattern of sero-conversion and disease transformation.

    Lymphatic filariasis (LF) is focally endemic in Egypt where the female mosquito, Culex pipiens, is responsible for its transmission. The aim of the study was to investigate the impact of implementation of the 13th round of MDA in two Egyptian villages in the Menoufyia Governorate area after failing the transmission assessment survey (TAS) in 2005 using two methods, and to decide whether it is safe to stop MDA in these, as well as in similar implementation units (IUs). To achieve this aim, both the immunochromatographic card test (ICT) and molecular xenomonitoring (MX) techniques were employed. Read More

    Chagas disease and leishmaniasis are neglected tropical diseases (NTDs) endemic in developing countries. Although there are drugs available for their treatment, efforts on finding new efficacious therapies are continuous. The natural lignans grandisin (1) and veraguensin (2) show activity against trypomastigote T. Read More

    Shifts in the ecological niche of Lutzomyia peruensis under climate change scenarios in Peru.
    Med Vet Entomol 2017 Feb 2. Epub 2017 Feb 2.

    The Peruvian Andes presents a climate suitable for many species of sandfly that are known vectors of leishmaniasis or bartonellosis, including Lutzomyia peruensis (Diptera: Psychodidae), among others. In the present study, occurrences data for Lu. peruensis were compiled from several items in the scientific literature from Peru published between 1927 and 2015. Read More

    Evaluation of a hypothetical protein for serodiagnosis and as a potential marker for post-treatment serological evaluation of tegumentary leishmaniasis patients.

    The serodiagnosis for tegumentary leishmaniasis (TL) presents problems related to the sensitivity and/or specificity of the tests. In the present study, an enzyme-linked immunosorbent assay (ELISA) technique was used to evaluate the performance from a Leishmania braziliensis hypothetical protein, LbHyM, in an attempt to compare its serological reactivity with a soluble Leishmania antigenic preparation (SLA) for the serodiagnosis of cutaneous (CL) and mucosal (ML) leishmaniasis. LbHyM was predicted to be a kinesin-like protein by bioinformatics tools. Read More

    Correlation of Rk39-Specific Antibodies and Thyroid Function in Patients with Visceral Leishmaniasis.
    Eurasian J Med 2016 Oct;48(3):181-185
    Department of Microbiology, Diyala University College of Medicine, Baqubah, Iraq.
    Objective: This study aimed to determine whether anti-rK39 antibodies were diagnostic markers for visceral leishmaniasis (kala-azar) and to evaluate the correlation between age and gender in disease occurrence in Iraqi patients. In addition, it aimed to evaluate the correlation between thyroid hormones, i.e. Read More

    Leishmaniases are a group of neglected tropical diseases (NTDs) caused by protozoan parasites from >20 Leishmania species. Visceral leishmaniasis (VL), also known as kala-aza, is the most severe form of leishmaniasis, usually fatal in the absence of treatment in 95% of cases. The Morita-Baylis-Hillman adducts (MBHAs) are being explored as drug candidates against several diseases, one of them being leishmaniasis. Read More

    Transcriptional Profiling in Experimental Visceral Leishmaniasis Reveals a Broad Splenic Inflammatory Environment that Conditions Macrophages toward a Disease-Promoting Phenotype.

    Visceral Leishmaniasis (VL), caused by the intracellular protozoan Leishmania donovani, is characterized by relentlessly increasing visceral parasite replication, cachexia, massive splenomegaly, pancytopenia and ultimately death. Progressive disease is considered to be due to impaired effector T cell function and/or failure of macrophages to be activated to kill the intracellular parasite. In previous studies, we used the Syrian hamster (Mesocricetus auratus) as a model because it mimics the progressive nature of active human VL. Read More

    Leishmaniasis recidivans in Ethiopia: cutaneous and mucocutaneous features.

    Cutaneous leishmaniasis (CL) is endemic in Ethiopia. An unusual clinical form of this disease is leishmaniasis recidivans (LR), a prolonged, relapsing form of cutaneous leishmaniasis resembling tuberculosis of the skin that may persist for many years with a chronic and relapsing course. This rare variant has been shown to be caused by Leishmania tropica species in the Old World and by Leishmania braziliensis, Leishmania amazonensis, Leishmania panamensis, and Leishmania guyanensis in the New World, as reported in various studies.

    Progressive Perforation of the Nasal Septum due to Leishmania major: A Case of Mucosal Leishmaniasis in a Traveler.
    Am J Trop Med Hyg 2017 Jan 30. Epub 2017 Jan 30.
    Division of Infectious Diseases and Tropical Medicine, Department of Medicine I, Medical University of Vienna, Vienna, Austria
    This report describes a case of mucosal leishmaniasis caused by Leishmania major with destructive perforation of the nasal septum illustrating the diagnostic challenges of a rare clinical presentation of L. major infection in a traveler. The atypical presentation may have been associated with the use of cortisone as a potential trigger for the progressive destruction of the nasal septum. Read More
