  • Leishmaniasis in the United States: Emerging Issues in a Region of Low Endemicity
    microorganisms Review Leishmaniasis in the United States: Emerging Issues in a Region of Low Endemicity John M. Curtin 1,2,* and Naomi E. Aronson 2 1 Infectious Diseases Service, Walter Reed National Military Medical Center, Bethesda, MD 20814, USA 2 Infectious Diseases Division, Uniformed Services University, Bethesda, MD 20814, USA; [email protected] * Correspondence: [email protected]; Tel.: +1-011-301-295-6400 Abstract: Leishmaniasis, a chronic and persistent intracellular protozoal infection caused by many different species within the genus Leishmania, is an unfamiliar disease to most North American providers. Clinical presentations may include asymptomatic and symptomatic visceral leishmaniasis (so-called Kala-azar), as well as cutaneous or mucosal disease. Although cutaneous leishmaniasis (caused by Leishmania mexicana in the United States) is endemic in some southwest states, other causes for concern include reactivation of imported visceral leishmaniasis remotely in time from the initial infection, and the possible long-term complications of chronic inflammation from asymptomatic infection. Climate change, the identification of competent vectors and reservoirs, a highly mobile populace, significant population groups with proven exposure history, HIV, and widespread use of immunosuppressive medications and organ transplant all create the potential for increased frequency of leishmaniasis in the U.S. Together, these factors could contribute to leishmaniasis emerging as a health threat in the U.S., including the possibility of sustained autochthonous spread of newly introduced visceral disease. We summarize recent data examining the epidemiology and major risk factors for acquisition of cutaneous and visceral leishmaniasis, with a special focus on Citation: Curtin, J.M.; Aronson, N.E.

  • Manual for the Diagnosis and Treatment of Leishmaniasis
    Republic of the Sudan Federal Ministry of Health Communicable and Non-Communicable Diseases Control Directorate MANUAL FOR THE DIAGNOSIS AND TREATMENT OF LEISHMANIASIS November 2017 Acknowledgements The Communicable and Non-Communicable Diseases Control Directorate (CNCDCD), Federal Ministry of Health, Sudan, would like to acknowledge all the efforts spent on studying, controlling and reducing morbidity and mortality of leishmaniasis in Sudan, which culminated in the formulation of this manual in April 2004, updated in October 2014 and again in November 2017. We would like to express our thanks to all National institutions, organizations, research groups and individuals for their support, and the international organization with special thanks to WHO, MSF and UK- DFID (KalaCORE). I Preface Leishmaniasis is a major health problem in Sudan. Visceral, cutaneous and mucosal forms of leishmaniasis are endemic in various parts of the country, with serious outbreaks occurring periodically. Sudanese scientists have published many papers on the epidemiology, clinical manifestations, diagnosis and management of these complex diseases. This has resulted in a better understanding of the pathogenesis of the various forms of leishmaniasis and has led to more accurate and specific diagnostic methods and better therapy. Unfortunately, many practitioners are unaware of these developments and still rely on outdated diagnostic procedures and therapy. This document is intended to help those engaged in the diagnosis, treatment and nutrition of patients with various forms of leishmaniasis. The guidelines are based on publications and experience of Sudanese researchers and are therefore evidence based. The guidelines were agreed upon by top researchers and clinicians in workshops organized by the Leishmaniasis Control response at the Communicable and Non-Communicable Diseases Control Directorate, Federal Ministry of Health, Sudan.
