RESUMO

ABSTRACT Introduction: Thyroid storm is a life-threatening condition caused by an elevated release of T3 and T4. Its incidence is 0.20/100 000 inhabitants, with reported mortality rates of up to 30%. Due to its refractory nature, few therapeutic options are available, but plasma exchange is considered a potentially useful strategy for its treatment. Case presentation: A 17-year-old female patient was admitted to the emergency department of a tertiary care institution due to the onset of symptoms approximately 25 days before consultation, consisting of palpitations, dyspnea at rest, orthopnea, chest and abdominal pain, asthenia, adynamia, dizziness, headache, and liquid stools. In addition, the patient had a history of hyperthyroidism treated on an outpatient basis. Thyroid storm was diagnosed considering the symptoms and a score of 65 on the Burch-Wartofsky scale. As a result, the patient was admitted to the hospital, and pharmacological management was initiated, although no improvement was achieved. On the third day of hospitalization, her condition deteriorated and she had a seizure, which led to consider a refractory thyroid storm. This condition was satisfactorily treated with plasma exchange as a bridge therapy prior to emergency thyroidectomy. Conclusion: Plasma exchange therapy allows a rapid removal of thyroid hormones. Although its implementation is not widely disseminated in clinical practice guidelines, there is evidence of a decrease in the risk of perioperative complications and a successful evolution after its use as a bridge therapy before performing thyroidectomy in patients with refractory thyroid storm.


RESUMEN Introducción. La tormenta tiroidea es una afectación orgánica severa que se produce por la liberación de triyodotironina (T3) y tiroxina (T4). Su incidencia es de 0.20 casos por cada 100 000 habitantes y puede conllevar a una mortalidad de hasta el 30%. Esta es una entidad refractaria para la cual existen pocas opciones terapéuticas, siendo la terapia de intercambio plasmático una estrategia potencialmente útil para su manejo. Presentación del caso. Paciente femenina de 17 años quien ingresó al servicio de urgencias de una institución de tercer nivel de atención por un cuadro clínico de aproximadamente 25 días de evolución consistente en palpitaciones, disnea en reposo, ortopnea, dolor torácico y abdominal, astenia, adinamia, mareo, cefalea y deposiciones líquidas; como antecedentes presentaba hipertiroidismo en manejo ambulatorio. Dada la sintomatología y gracias a que se obtuvo un puntaje de 65 en la escala de Burch-Wartofsky, se diagnosticó tormenta tiroidea, se dio orden de hospitalización y se inició manejo farmacológico, con el cual no se logró una mejoría. Al tercer día de hospitalización la joven presentó deterioro clínico continuo y un episodio convulsivo, por lo que se consideró tormenta tiroidea refractaria que fue tratada satisfactoriamente con terapia de intercambio plasmático como terapia puente previo a tiroidectomía total de urgencia. Conclusión. La terapia de intercambio plasmático permite una rápida remoción de las hormonas tiroideas y, aunque su implementación no es ampliamente difundida por las guías de práctica clínica, existe evidencia que demuestra una disminución en el riesgo de complicaciones perioperatorias y una evolución exitosa tras su uso como terapia puente previo a tiroidectomía en pacientes con tormenta tiroidea refractaria.

RESUMO

INTRODUCTION: Multicentric Castleman's disease is a rare benign lymphoproliferative disorder that involves multiple enlarged lymph nodes in different areas of the body. Recently, a unique clinic pathological variant of this disease called TAFRO syndrome has been described. CASE REPORT: A 23-year-old male with a history of one year and six months of evolution characterized by generalized lymphadenopathy with, night diaphoresis, dyspnea and weight loss. At the third month, hypertension was diagnosed and 8 months later type 2 diabetes mellitus. After his admission, microcytic anemia, thrombocytopenia, renal dysfunction, pleural effusion and ascites were documented. Based on the findings of the physical examination, a computed tomography scan was performed, where multiple lymph nodes and hepatosplenomegaly were identified. A lymph node biopsy was performed, which reported Castleman's disease, considering then a diagnosis of TAFRO syndrome due to its association with thrombocytopenia, microcytic anemia, anasarca, fever, renal dysfunction, adenomegaly and hepatosplenomegaly. CONCLUSIONS: There are still doubts about whether it corresponds to a different disease or a subtype of the Castleman disease. It is more frequent in women, occurs in the middle-aged and elderly and given its heterogeneous presentation, it usually represents a diagnostic challenge. Although its management is not standardized, therapeutic options include immunosuppressant such as steroids, cyclosporine, rituximab and anti-IL6.


INTRODUCCIÓN: La enfermedad de Castleman multicéntrica es un raro trastorno linfoproliferativo benigno que compromete múltiples nódulos linfáticos agrandados en distintas zonas del cuerpo. Se ha descrito una variante clinicopatológica única de esta enfermedad, denominada síndrome TAFRO. CASO CLÍNICO: Varón de 23 años con un cuadro de 1 año y 6 meses de evolución caracterizado por adenopatías generalizadas, diaforesis nocturna, disnea y pérdida de peso. Al tercer mes se diagnosticó hipertensión arterial, y 8 meses después, diabetes mellitus tipo 2. Tras su ingreso se documentó anemia microcítica, trombocitopenia, disfunción renal, derrame pleural y ascitis. Por los hallazgos de la exploración física, se realizó tomografía computarizada, que identificó múltiples adenomegalias y hepatoesplenomegalia. Se realizó biopsia de ganglio linfático, cuyo reporte informó enfermedad de Castleman, considerándose entonces el diagnóstico de síndrome TAFRO por su asociación con trombocitopenia, anemia microcítica, anasarca, fiebre, disfunción renal, adenomegalias y hepatoesplenomegalia. CONCLUSIONES: Aún existen dudas sobre si el síndrome TAFRO corresponde a una enfermedad diferente o a un subtipo de la enfermedad Castleman. Es más frecuente en mujeres y en personas de mediana edad o ancianas, y dada su presentación heterogénea suele representar un reto diagnóstico. Aunque su manejo no se encuentra estandarizado, las opciones terapéuticas incluyen inmunosupresores como esteroides, ciclosporina, rituximab y anti-IL6.

RESUMO

ABSTRACT Introduction: The fourth-generation ELISA human immunodeficiency virus (HIV) screening test has a high sensitivity and specificity >99% to detect both antigens and antibodies. Estimates are that only 0.5% yield false positive results. Case description: 61-year-old female patient with a clinical picture consisting of malaise, unqualified fever, asthenia and adynamia. Laboratory tests revealed anemia, so a Coombs test was performed, obtaining a positive result along with other findings of mixed autoimmune hemolytic anemia. Two fourth-generation ELISA HIV screening tests were performed obtaining positive results. Given the national recommendations on the diagnosis of HIV infection, a viral load was performed, which turned out to be negative, so the result was considered a false positive. Discussion: Clinical and biological factors are related to false positive results. There are descriptions about autoimmunity phenomena, such as systemic lupus erythematosus or autoimmune hemolytic anemia, with few cases in older adults. Conclusions: Rapid tests have changed the diagnosis of HIV infection worldwide; however, like any other diagnostic test, they may yield false positive results with differential diagnoses, including autoimmune hemolytic anemia.


RESUMEN Introducción. La prueba de tamizaje para virus de la inmunodeficiencia humana (VIH) con ELISA de cuarta generación tiene gran sensibilidad y una especificidad >99% para detectar tanto antígenos como anticuerpos. Se estima que solo el 0.5% son falsos positivos. Presentación del caso. Paciente femenino de 61 años con cuadro clínico consistente en malestar general, fiebre no cuantificada, astenia y adinamia. En los paraclínicos se evidenció anemia, por lo que se realizó prueba de Coombs, la cual resultó positiva junto con otros hallazgos de anemia hemolítica autoinmune mixta. Se realizaron dos pruebas de tamizaje para VIH con técnica ELISA de cuarta generación que fueron positivas. Dadas las recomendaciones nacionales sobre el diagnóstico de la infección por VIH, se realizó una carga viral que resultó ser negativa, por lo que se consideró el resultado como un falso positivo. Discusión. Factores clínicos y biológicos se relacionan con resultados falsos positivos. Existen descripciones sobre fenómenos de autoinmunidad, como el lupus eritematoso sistémico o la anemia hemolítica autoinmune, con pocos casos en adultos mayores. Conclusiones. Las pruebas rápidas han cambiado el diagnóstico de la infección por VIH en el mundo; sin embargo, como toda prueba diagnóstica, tienen falsos positivos con diagnósticos diferenciales, incluidos la anemia hemolítica autoinmune.

RESUMO

Resumen: ANTECEDENTES: Estudios previos han encontrado variabilidad en la prevalencia del síndrome metabólico según diferentes definiciones. OBJETIVO: Determinar el grado de concordancia entre diferentes definiciones en una cohorte colombiana de base poblacional. MATERIAL Y MÉTODO: Estudio de cohorte prospectivo realizado en pacientes con edades comprendidas entre 15 y 64 años. Se realizó medición estandarizada de los diferentes factores de riesgo cardiovascular en 2001, 2007 y 2013. Se realizó un análisis univariado para describir la distribución de los factores de riesgo cardiovascular según las definiciones de síndrome metabólico propuestas por la Organización Mundial de la Salud (OMS), el Adult Panel Treatment III (ATPIII) y la Federación Internacional de Diabetes (IDF). El análisis de concordancia se realizó de acuerdo con el índice de concordancia Kappa. RESULTADOS: En 2001 se incluyeron 243 participantes. El 67% eran mujeres. La edad promedio fue de 36 años. La prevalencia del síndrome metabólico según las definiciones de la OMS, ATPIII e IDF fue de 5.2, 7 y 11.3% en 2001, 11.8, 9.5 y 17% en 2007 y 24, 17.3 y 29% en 2013, respectivamente. Se documentó un grado de acuerdo moderado entre las diferentes definiciones. CONCLUSIÓN: Existe variabilidad en la prevalencia del síndrome metabólico según cada una de las diferentes definiciones utilizadas, es mayor cuando se utiliza la definición propuesta por la IDF, probablemente debido al punto de corte utilizado para definir la obesidad.


Abstract: BACKGROUND: Previous studies have found variability in the prevalence of metabolic syndrome according different definitions. OBJECTIVE: To determine the degree of agreement between different definitions in a Colombian population-based cohort. MATERIAL AND METHOD: A prospective cohort conducted in patients aged between 15 to 64 years. Standardized measurements of cardiovascular risk factors were made in 2001, 2007 and 2013. Univariate analysis was performed to describe the distribution of these cardiovascular risk factors according to metabolic syndrome definition proposed by World Health Organization (WHO), Adult Panel Treatment III (ATPIII) and International Diabetes Federation (IDF). Concordance analysis was performed according to the Kappa concordance index. RESULTS: In 2001, 2432 participants were included, 67% were women. The average age was 36 years. The prevalence of metabolic syndrome according to the WHO, AT- PIII and IDF definitions was 5.2%, 7%, and 11.3% in 2001, 11.8%, 9.5% and 17% in 2007 and 24%, 17.3% and 29% in 2013, respectively. There evidence of moderate agreement between definitions. CONCLUSION: There is variability in the prevalence of metabolic síndrome according to each of the different definitions used being higher when using the definition proposed by the IDF, probably due to the cut-off point used to define obesity.

RESUMO

BACKGROUND: In the last three years, chikungunya virus disease has been spreading, affecting particularly the Americas, producing more than two million cases. In this setting, not only new disease-related epidemiological patterns have been found, but also new clinical findings have been reported by different research groups. These include findings on the cardiovascular system, including clinical, electrocardiographic and echocardiographic alterations. METHODS: We performed a systematic review looking for reports about cardiovascular compromise during chikungunya disease. Cardiac compromise is not so common in isolated episodes; but countries where chikungunya virus is an epidemic should be well informed about this condition. We used 6 bibliographical databases as resources: Medline/Pubmed, Embase, ScienceDirect, ClinicalKey, Ovid and SciELO. Dengue reports on cardiovascular affectation were included as well, to compare both arbovirus' organic affectations. Articles that delved mainly into the rheumatic articular and cutaneous complications were not considered, as they were not in line with the purpose of this study. The type of articles included were reviews, meta-analyses, case-controls, cohort studies, case reports and case series. RESULTS: Originally based on 737 articles, our reviewed selected 40 articles with 54.2% at least mentioning CHIKV cardiovascular compromise within the systemic affectation. Cardiovascular manifestations can be considered common and have been reported in France, India, Sri Lanka, Malaysia, Colombia, Venezuela and USA, including mainly, but no limited to: hypotension, shock and circulatory collapse, Raynaud phenomenon, arrhythmias, murmurs, myocarditis, dilated cardiomyopathy, congestive insufficiency, heart failure and altered function profile (Troponins, CPK). CONCLUSIONS: Physicians should be encouraged to keep divulgating reports on the cardiovascular involvement of chikungunya virus disease, to raise awareness and ultimately encourage suitable diagnosis and intervention worldwide.

RESUMO

El sistema nervioso central es uno de los focos extrapulmonares afectados con mayor frecuencia por tuberculosis, no obstante, el tuberculoma epidural espinal es considerado una rareza. Se presenta el caso de un paciente de cuatro años de edad, quien consulta por cuadro de cuadriparesia progresiva. Al examen de líquido cefalorraquídeo se evidenció disociación proteínico celular diagnosticándose síndrome de Guillain Barré, sin embargo, tras la aparición de signos meníngeos, se realizó una resonancia nuclear magnética de columna en la que se evidenció lesión compresiva a nivel cervicodorsal que fue posteriormente explorada quirúrgicamente por neurocirugía, encontrándose una lesión epidural cuyo estudio microbiológico, cultivo y estudio de reacción en cadena de la polimerasa se reportaron positivos para Mycobacterium tuberculosis, por lo que se inició tratamiento antituberculoso observándose mejoría clínica y progresiva con recuperación de la marcha tras el procedimiento quirúrgico. MÉD.UIS. 2016;29(2):155-9.


The central nervous system is one of the most affected focus in extrapulmonary tuberculosis, however, spinal epidural tuberculoma is considered very unusual. We present a clinical report of a four years old patient who presented with clinical symptoms of a progressive quadriparesis. The cerebroespinal fluid examination showed protein-cell dissociation, and the diagnosis of Guillain Barré syndrome was made. However, because it called the attention the appearance of meningeal signs, a magnetic resonance imaging was performed, and evidenced a compressive lesion in the cervicodorsal level. It was explored by neurosurgery, finding an epidural lesion studied by cultures and polymerase chain reaction. Both reported positive results for Mycobacterium tuberculosis. The anti-tuberculosis treatment was started and a progressive clinical improvement was observed with recuperation of the gait after the surgical procedure.MÉD.UIS. 2016;29(2):155-9.

RESUMO

El curso normal del embarazo implica una serie de cambios inmunológicos que permiten el desarrollo armónico fetal. En mujeres con pérdida recurrente de la gestación, diversas etiologías se han relacionado como desencadenantes de dichas pérdidas; jugando el factor autoinmune un papel cada vez más importante. En el presente artículo, a partir de una búsqueda sistemática de información, se exponen en detalle los aspectos inmunológicos del embarazo normal, así como las alteraciones que a este nivel se presentan en mujeres con aborto recurrente. Además, se realiza una orientación diagnóstica y se exponen las diversas opciones terapéuticas utilizadas, haciendo énfasis en la necesidad de establecer protocolos estandarizados para el manejo de esta entidad.


Normal development of the pregnancy involves a number of immunological changes that allow harmonic fetal development. In women with recurrent pregnancy loss several etiologies have been implicated as triggers of such losses; autoimmune factor is nowadays playing an increasingly more important roll. In this article, based on a systematic search of information, are exposed in details the immunological aspects of normal pregnancy, as well as the immune alterations that occur in women with recurrent abortion. In addition, a diagnostic guidance is made and the various therapeutic options used are pointed out, emphasizing the need to establish standardized protocols for the management of this entity.

RESUMO

PURPOSE OF REVIEW: Arthropods are a significant cause of human skin lesions and infections, especially in Latin America. This review summarizes recent articles on the cutaneous manifestations of arthropod-borne diseases, with an emphasis on those diseases causing direct skin damage but also considering those systemic diseases with cutaneous manifestations. RECENT FINDINGS: Studies have shown a variety and increase of cutaneous manifestations caused by arthropod-borne infections, including petechiae, purpura, ulcers, nodules, atrophic, miliary and hyperpigmented lesions. Although unspecific, when considering other features they become a useful tool in the diagnostic approach. Unusual cutaneous presentation of these diseases has been found to be associated with development of immunity, virulent strain, drug resistance and immunosuppressive states. Also, because of globalization, climate change and large-scale migration, these manifestations have spread to new areas. SUMMARY: Cutaneous manifestations of arthropod-borne infections are varied and nonspecific. Their atypical presentations are mainly related to immune impairment and strain virulence. When considering a patient with skin lesions, other clinical and laboratory features must be taken into account in order to make an accurate diagnostic approach.

RESUMO

La toxocariasis es una infección parasitaria producida por un helminto que en el ser humano no alcanza su estadio adulto. El hombre es para sus especies, Toxocara canis y Toxocara cati, un hospedador paraténico. Dicha infección puede producir el síndrome de larva migrans visceral, el síndrome de larva migrans ocular y la toxocariasis inaparente. En el síndrome de larva migrans visceral el compromiso de órganos puede incluir hígado, pulmón, piel, sistema nervioso, musculoesquelético, riñón y corazón. Sobre este último, cada vez se reconoce más la importancia que pueden tener las manifestaciones cardiovasculares de la toxocariasis y la relevancia clínica de considerarlas. En el presente artículo, haciendo una búsqueda sistemática de información, se revisan los principales aspectos clinicopatológicos de las manifestaciones cardiovasculares de la toxocariasis incluyendo su fisiopatología, hallazgos de laboratorio, diagnóstico y opciones terapéuticas, con el objeto de llamar la atención acerca de la importancia de esta zoonosis y su relevancia para la medicina cardiovascular en adultos y en niños.


Toxocariasis is a parasitic infection produced by helminths that cannot reach their adult stage in humans. For their etiological species (Toxocara canis and Toxocara cati), man is a paratenic host. Infection by such helminths can produce a variety of clinical manifestations, such as: visceral larvae migrans syndrome, ocular larvae migrans syndrome and covert toxoca-riasis. In the visceral larvae migrans syndrome, the organs that are mainly involved include liver, lungs, skin, nervous system, muscles, kidneys and the heart. Regarding the latter, the importance of cardiovascular manifestations in toxocariasis, as well as its clinical relevance, has increasingly begun to be recognized. The current article is based on a systematic information search, focused mainly on the clinical and pathological aspects of cardiovascular manifestations in toxocariasis, including its pathophysiology, laboratory findings, diagnosis and therapeutical options, with the objective of highlighting its importance as a zoonosis and its relevance to the fields of cardiovascular medicine in adults and children.

RESUMO

Tuberculosis (TB) is one of the most important infectious diseases globally and its occurrence among risk groups —those with HIV/AIDS, indigenous populations, and individuals living in crowded conditions and/or extreme poverty such as homeless persons all the more 1-4. Within the world morbidity and mortality burden of TB, special consideration has been recently given to disease incidence among homeless persons, not only because they can be a risk, a source of transmission and a hub for persistent presence of the pathogen, but also for their varying clinical evolution and outcome 5-8. Despite the above, there are few published studies regarding TB among homeless persons in Latin America. Some isolated references can be found at Medline and Scopus from Brazil and Puerto Rico 9,10, but none from Colombia. In this country, only approaches to the social aspects 11 and public policies regarding TB among this population 12, have been reported


La tuberculosis (TB) es una de las enfermedades infecciosas más importantes a nivel mundial y su incidencia entre los grupos de riesgo, aquellos con VIH/SIDA, las poblaciones indígenas y los individuos que viven en condiciones de hacinamiento y/o extrema pobreza, como las personas sin hogar, es aún mayor. Dentro de la carga de morbilidad y mortalidad mundial de la tuberculosis, recientemente se ha prestado especial atención a la incidencia de la enfermedad entre las personas sin hogar, no sólo porque pueden ser un riesgo, una fuente de transmisión y un foco de presencia persistente del patógeno, sino también por su diferente evolución clínica y resultados 5-8. A pesar de lo anterior, existen pocos estudios publicados sobre la TB en personas sin hogar en América Latina. Se pueden encontrar algunas referencias aisladas en Medline y Scopus de Brasil y Puerto Rico 9,10, pero ninguna de Colombia. En este país sólo se han reportado aproximaciones a los aspectos sociales 11 y a las políticas públicas respecto a la TB en esta población 12

RESUMO

Los mecanismos que subyacen la reproducción humana son muy complejos, por lo que cualquier pérdida gestacional implica el tener que considerar diversas etiologías, más aun si se trata de pérdidas gestacionales recurrentes dentro de las que la inmunidad juega un papel especialmente importante. Desde hace varias décadas, el factor aloinmune ha sido reconocido como un desencadenante frecuente de la interrupción del embarazo, haciéndose de esta forma relevante su estudio en mujeres con aborto recurrente. En el presente artículo, a partir de una búsqueda sistemática de información, se revisan con detalle los aspectos relacionados con la fisiopatología, el diagnóstico y el tratamiento del aborto recurrente de etiología aloinmune, buscando con esto sensibilizar al profesional de la salud sobre su consideración ante una mujer con pérdida recurrente de la gestación.


The mechanisms underlying the human reproduction are very complex, so any pregnancy loss implies the need of considering various etiologies, even more if those pregnancy losses are recurrent within which the immunity plays an important role. Since decades, the alloimmune factor has been recognized as a frequent trigger of the pregnancy interruption, thus becoming relevant its study in women with recurrent miscarriage. In the present article, through a systematic search of information, details concerning to the physiopathology, diagnosis and treatment of the recurrent miscarriage of alloimmune etiology are reviewed, looking to sensitize the health professional about its consideration when evaluating a woman with recurrent pregnancy loss.

RESUMO

Introducción: La tuberculosis (TB) es un importante problema de salud tanto a nivel mundial como también en Colombia, por lo cual se requiere intensificar más acciones en salud y en investigación. Se realizó una evaluación bibliométrica de las contribuciones de la literatura colombiana sobre TB con el objeto de determinar el nivel de producción en la materia. Materiales y métodos: Estudio de producción colombiana en TB en las bases MEDLINE/ GOPUBMED (1809-2012), Scopus (1959-2012), SciELO Colombia (20042012) e IMBIOMED (2005-2012). Se incluyen todos los tipos de estudios, caracterizándolos por años, cooperación internacional (CI), ciudad de origen de la publicación (COP), revista de publicación (RP) y autores con mayor contribución (AMC). Resultados: En MEDLINE, se encontraron 232 artículos (0,12% del total en TB, 0,49/100.000 hab.), de los cuales 52,2% fueron 20052012, promedio 2007-2011 de 19,6±5,1. La CI se observó en 21,9%. Bogotá, Medellín y Cali publicaron 65,52% de los artículos, 16,4% en Biomédica, 5,2% en Revista de Salud Pública y 4,3% en IJTLD. En MEDLINE el AMC es Luís F. García (Universidad de antioquia). En scopus los resultados son similares a MEDLINE (n=168, 0,08%). En SciELO sólo existen 29 registros (de 30) y en IMBIOMED 35 (de 513, 6,8%). Discusión: La producción científica en TB en Colombia es baja, no solo al compararla con países desarrollos (EUA, 4,08 artículos/100.000 hab.) sino con otros en América Latina incluso de menor incidencia como chile (19 casos/100.000 hab.) pero con una productividad 2,2 veces mayor (1,09 artículos/100.000 hab.). Un mayor fomento de la investigación, desde pregrado, una mayor interacción entre organismos públicos y privados, así como mayor cooperación académica e internacional, podrían permitir disminuir dichas brechas, incrementar la publicación científica y que la aplicación de dichos conocimientos generados en el propio país contribuya a mejorar la epidemiología y los diferentes aspectos de la enfermedad.


Introduction: Tuberculosis (TB) is an important public health problem, globally as well in Colombia. For these reasons more actions in health and research should be intensified. A bibliometric assessment of the colombian contributions to the biomedical literature on TB with the objective to determinate the level of production on it was done. Methods: Bibliometric study of the colombian production on TB in the databases MEDLINE/GOPUBMED (1809-2012), SCOPUS (1959-2012), SCIELO Colombia (2004-2012) and IMBIOMED (2005-2012). Ah kind of studies, analyzing by years, international cooperation (IC), publication origin city (POC), publication journal (PJ) and authors with more contribution (AMC) were included. Results: at MEDLINE, 232 articles were found (0.12% from the total on TB, 0.49/100,000 hab.), from them 52.2% were 2005-2012, mean 2007-2011 of 19.6±5.1. IC was recorded in 21.9%. Bogotá, Medellín and Cali published 65.52% of the articles, 16.4% at Biomédica, 5.2% at Revista de Salud Pública and 4.3% at IJTLD. At MEDLINE the AMC was Luís F. García (Universidad de Antioquia). At SCOPUS results were similar to MEDLINE (n=168, 0.08%). At SciELO only 29 records were found (out of 30) and at IMBIOMED 35 (of 513, 6.8%). Discussion: scientific production on TB in Colombia is low, not just comparing it with developed countries (UsA, 4.08 articles/100,000 hab.) but also with others in Latin America with even lower TB incidence such as Chile (19 cases/100,000 hab.) but with a better productivity 2.2 times higher (1.09 articles/100,000 hab.). A higher promotion of research, beginning in undergraduate studies, better interaction between public and private organizations, as well more academic and international cooperation, would allow to decrease those gaps, increase scientific publication and let that the application of that generated knowledge in the same country contribute to improve the TB epidemiology and different aspects of disease.
