RESUMO

INTRODUCTION: Knowledge of the geographical distribution of Leishmania species allows guiding the sampling to little-studied areas and implementing strategies to define risk zones and priority areas for control. OBJECTIVE: Given that there is no publication that collects this information, the search, review, and compilation of the available scientific literature that has identified species in Colombia is presented in this paper. MATERIALS AND METHODS: A bibliographic search was performed in PubMed, Web of Knowledge, Google Scholar, SciELO and LILACS with the terms "(Leishmania OR Leishmaniasis) AND species AND Colombia", without restrictions on publication year, language or infected organism; records of national scientific events and repositories of theses from Colombian universities were also included. RESULTS: Eighty-six scientific documents published between 1985 and 2017 were found in which the species of Leishmania and their geographical origin were indicated. The species reported, in descending order of frequency, were: Leishmania (Viannia) panamensis, L. (V.) braziliensis, L. (V.) guyanensis, L. (Leishmania) infantum, L. (L.) amazonensis, L. (L.) mexicana, L. (V.) colombiensis, L. (V.) lainsoni and L. (V.) equatorensis; the last three were found with the same frequency. Leishmania species were reported from 29 departments. CONCLUSION: Information on the distribution of Leishmania species in Colombia is limited; therefore, it is necessary to gather existing data and propose studies that consolidate the distribution maps of Leishmania species in Colombia. This would allow the detection of areas where species have not been identified as well as the comparison of existing parasite and vector distributions.


Introducción. El conocimiento de la distribución geográfica de las especies de Leishmania permite orientar el muestreo hacia áreas poco estudiadas e implementar estrategias para detectar zonas de riesgo y áreas prioritarias de control. Objetivo. Dado que no existe una publicación que reúna esta información, se planteó la revisión y compilación de la literatura científica disponible de estudios de identificación de especies del país. Materiales y métodos. Se llevó a cabo una búsqueda bibliográfica en PubMed, Web of Knowledge, Google Académico, SciELO y Lilacs con los términos "(Leishmania OR Leishmaniasis) AND especie AND Colombia", así como en memorias de eventos científicos nacionales y repositorios de tesis y trabajos de grado de universidades del país. Resultados. Se encontraron 86 documentos científicos publicados entre 1985 y 2017, en los cuales se informaron la especie de Leishmania y el origen geográfico. Las especies circulantes reportadas, en su orden de frecuencia, fueron: Leishmania (Viannia) panamensis, L. (V.) braziliensis, L. (V.) guyanensis, L. (Leishmania) infantum, L. (L.) amazonensis, L. (L.) mexicana, L. (V.) colombiensis, L. (V.) lainsoni y L. (V.) equatorensis, las últimas tres, con igual frecuencia. Los reportes proceden de 29 departamentos. Conclusión. La información de la distribución de las especies de Leishmania en Colombia es limitada. Por lo tanto, se necesita reunir los datos existentes y plantear trabajos que permitan consolidar el mapa de distribución de las especies en el país, lo cual permitiría detectar las zonas sin información de las especies circulantes y establecer la concordancia entre su distribución y la de los vectores.

RESUMO

Introducción. El mapa de la distribución de especies de Leishmania en Colombia no se ha actualizado desde hace siete años. Objetivo. Describir la distribución de las especies de Leishmania a partir de los aislamientos de pacientes consultantes al Instituto Nacional de Dermatología durante el período 1995 a 2005 Materiales y métodos. Se realizó un estudio descriptivo de distribución geográfica de las especies de Leishmania, a partir de los aislamientos obtenidos de 137 pacientes consultantes al Instituto Nacional de Dermatología Federico Lleras Acosta E. S. E, con diagnóstico confirmado de leishmaniasis. Se revisó la historia clínica obteniendo la información de forma clínica, sitio probable de infección, edad y género. Se tomaron y cultivaron muestras de las lesiones y los aislamientos se tipificaron por anticuerpos monoclonales, comparando el 10 por ciento de los resultados con los obtenidos por reacción en cadena de la polimerasa (PCR) y patrones isoenzimáticos.Resultados. La frecuencia encontrada de los 137 aislamientos fue: Leishmania panamensis 74,45 por ciento; Leishmania braziliensis 15,33 por ciento; Leishmania guyanensis 0,73 por ciento; Complejo Leishmania mexicana 3,65 por ciento, Leishmania mexicana 5,11 por ciento y el 0,73 por ciento restante correspondió a un aislamiento que no se pudo caracterizar por anticuerpos monoclonales. La distribución de L. braziliensis, L. panamensis y L. guyanensis fue concordante con lo reportado en estudios anteriores pero para las especies del complejo L. mexicana se encontraron procedencias no reportadas previamente: Caldas, Santander, Cundinamarca, Caquetá, Casanare, Cauca y Valle del Cauca. Conclusión. El complejo L. mexicana presenta una distribución más amplia de la reportada previamente. La utilidad de los monoclonales especie-específicos, los patrones isoenzimáticos y la PCR para L. mexicana y L. amazonensis fue limitada.


Introduction. The Colombian distribution map of Leishmania species has not been updated since seven years ago. Objective. To describe the distribution of Leishmania species isolated from patients attended at the National Institute of Dermatology during the period 1995 to 2005. Materials and methods. A descriptive study of the geographic distribution of Leishmania species was made from 137 isolates obtained from patients consulting the National Institute of Dermatology "Federico Lleras Acosta E.S.E", with confirmed diagnosis of leishmaniasis. The clinical history was reviewed to obtain information on the clinical presentation, most probable place of infection, age and gender. Samples were taken and cultured and the isolates were typed by monoclonal antibodies, comparing 10% of the results with those obtained by PCR and isoenzymatic patterns. Results. L. panamensis accounted for 74.45% of the 137 isolates studied, L. braziliensis for 15.33%, L. guyanensis for 0.73%; L. mexicana complex for 3.65%, L. mexicana 5.11% and the remaining 0.73% corresponded to an isolate which could not be characterized by monoclonal antibodies. The distribution of L. braziliensis, L. panamensis and L. guyanensis was similar to that reported in previous studies but species of the L. mexicana complex, were found in patients from the departments of Caldas, Santander, Cundinamarca, Caquetá, Casanare, Cauca and Valle del Cauca, where they had not been previously reported. Conclusion. Species of the L. mexicana complex display a wider distribution than previously reported. The usefulness of species-specific monoclonal antibodies, isoenzymatic patterns, and PCR for identification of L. mexicana and L. amazonensis was limited.
