RESUMO

Introducción: Las tuberculides tuberculosas (TLTB) se subdividen en verdaderas de etiología atribuible al Mycobacterium tuberculosis y facultativas causadas por múltiples condiciones, entre ellas la tuberculosis. En Chile representan el 75% de las tuberculosis cutáneas en la región metropolitana (RM). Objetivo: caracterizar las TLTB de la RM de acuerdo a epidemiología, clínica, estudio y manejo terapéutico. Material y método: Estudio descriptivo retrospectivo del total de TLTB diagnosticadas por biopsia en los servicios de anatomía patológica de 4 hospitales públicos de la RM y un hospital privado de la RM en el quinquenio 2006-2010. Resultados: 83 casos de TLTB, 59% aportados por el sistema público, 84% de los pacientes fueron mujeres, 18% fueron tuberculides verdaderas y 82% tuberculides facultativas. A pesar de ser el tratamiento antituberculoso la elección en las tuberculides verdaderas, sólo se indicó en el 65% de los casos y de estos, 45% realmente lo realizó. Sólo el 4,5% de las tuberculides facultativas de esta serie tuvieron indicación de tratamiento antituberculoso, realizándose en el 100% de los casos. Conclusión: Existe seguimiento insuficiente a través del tiempo en estos pacientes, dificultando dimensionar el éxito real de los tratamientos indicados. Se evidencia una falla en la coordinación al momento de derivar los pacientes al programa de control de la tuberculosis.


Introduction: Tuberculids are subdivided in true tuberculids, which are associated to mycobacterium tuberculosis, and facultative tuberculids which can be caused by several conditions, including tuberculosis. In Chile tuberculids represent 75% of cutaneous tuberculosis in the metropolitan region (MR). Objective: to characterize tuberculids according to epidemiology, clinical, study and therapeutic management. Methods: Descriptive study of the total tuberculids diagnosed by biopsy in the pathology services of 4 public hospitals of the MRI and a private hospital of the MRI in the five-year period 2006- 2010. Results: 83 cases of tuberculids, 59% where provided by the public system, 84% of the patients were women, 18% were true tuberculids and 82% facultative tuberculids. Despite being antitubercular therapy the first line treatment for true tuberculids, this treatment was prescribed in 65% of cases and only 45% of these were actually treated. Only 4.5% of the facultative tuberculids in this series had indication of antitubercular therapy, performed in 100% of cases. Conclusions: There is insufficient follow up in these patients, making it difficult to assess the real success of the treatment. Is evident the lack of coordination when referring patients to the tuberculosis control program.

RESUMO

BACKGROUND: Mycobacterium peregrinum is a rapidly growing mycobacterium (RGM) that rarely causes skin infections. The correct identification of the specific RGM infecting the skin will enhance therapeutic success. OBJECTIVE: To highlight the importance of rapid and precise identification of the Mycobacterium involved in skin infections in order to enhance therapeutic success. METHODS: We describe an RGM skin infection in an immunocompetent patient. RESULTS: Classic methods (biochemical tests and culture) of RGM identification are time-consuming, and the histopathological features are not specific. Some molecular methods are reliable but expensive. The PRAhsp-65 is a simple procedure that is helpful in identifying the specific agent of an RGM. CONCLUSION: Although skin infections caused by M peregrinum are rare, they represent a substantial clinical challenge. Specific and more effective treatment options depend on the development of precise and rapid methods for identifying mycobacterial species.
