ResumenLa acidosis tubular renal distal es causada por un defecto en la excreción de iones de hidrogeno a nivel tubular distal, lo que aumenta el pH de la orina y disminuye el pH plasmático; esta es una enfermedad con varias manifestaciones clínicas asociadas. En este artículo se hace una revisión profunda sobre la acidosis tubular renal distal y se presenta el caso de tres hermanos (dos hombres y una mujer) con la entidad, siendo este uno de los primeros casos familiares reportados en Colombia. Los tres pacientes recibieron el diagnóstico durante el período de lactancia, presentaron nefrocalcinosis y tuvieron buena respuesta a la terapia con álcali iniciada de forma temprana, logrando eventualmente su suspensión. De manera curiosa, uno de los pacientes también presentó deficiencia de mevalonato quinasa con hiperinmunoglobulinemia D, una alteración no descrita con anterioridad. Esta asociación y la aparente falta de necesidad de continuar el manejo con álcali son atípicas a la luz del conocimiento actual, mereciendo especial consideración.
Introducción: la enfermedad coronaria es una de las principales causas de morbimortalidad a nivel mundial; se sabe que la diabetes mellitus tipo 2 (DM2) es un factor de riesgo importante para esta patología y que puede producir una forma asintomática o con manifestaciones atípicas. Objetivos: exponer los principales datos epidemiológicos, pronósticos y determinantes de la enfermedad coronaria asintomática en DM2 y discutir las formas de tamización y su utilidad en diabéticos asintomáticos. Materiales y métodos: se realizó una búsqueda en PubMed, LILACS y SciELO usando las palabras clave “Diabetes Mellitus, type 2”, “Coronary disease”, “Coronary Artery Disease”, “Coronary Vessels”, “Atherosclerosis”, “Arteriosclerosis”, “Asymptomatic Diseases”, “Asymptomatic”, “Silent” y “Myocardcial infarction”, ajustando la búsqueda según las necesidades de cada base de datos. Se incluyeron artículos que cumplieran los criterios de inclusión y no los de exclusión, a consideración de los autores, así como algunas referencias adicionales. Resultados: se revisó el título y resumen de 504 artículos encontrados en las bases de datos, tras lo cual se escogieron 81 para su lectura total. De ellos, 56 fueron incluidos, así como 48 publicaciones adicionales conocidas por los autores o referenciados en las artículos leídos, lo que dio un total de 104 artículos incluidos en la revisión final. Conclusiones: los pacientes con DM2 presentan altas prevalencias de enfermedad coronaria asintomática que aumentan en presencia de otros factores de riesgo cardiovascular o de mayor duración o progresión de la DM2. Si bien existen varios métodos anatómicos o funcionales para su detección, la tamización de esta población no ha mostrado beneficio alguno, por lo que no puede recomendarse de rutina en asintomáticos.
To study the risk of nephrotoxicity and the cost of treatment of colistin. METHODS: Patients admitted in ICU with resistant bacterial infections and on colistin for at least seven days were included in the study. They were observed for any change in Glomerular filtration rate and the risk of nephrotoxicity according to the RIFLE criteria after the colistin therapy. The GFR values before the initiation of treatment with colistin were compared with that after the end of regimen. The pre and post treatment GFR values were compared using non-parametric Wilcoxon Signed Ranks test. RESULTS: A total of 30 patients on colistin were observed during the study. The mean age of the patients was 45.47±16.45. The average APACHE II score was 15.87±5.82. There was no significant difference between the GFR of patients before and after treatment with colistin (p= 0.130). The average hospitalization cost was 255245.41±138099.29 and the average cost of colistin therapy was 31638.10±12625.90. CONCLUSIONS: This study showed that the nephrotoxic effect of colistin is not significant. There is a need to conduct more studies with a higher sample size to assess the risk of colistin-induced nephrotoxicity. The incidences of nephrotoxicity in the patients studied can be attributed to various other factors such as age, comorbidities etc. The cost of colistin therapy was substantial being more than one-tenth of the total hospitalization cost.
Background Rockall score is the most widely used prognostic scale for assessing risk of complications from non-varicose upper gastrointestinal bleeding (UGIB). Several studies have been conducted in adult populations with non-varicose UGIB in different parts of the world, with conflicting findings regarding the extent of association between the score and some morbidity and mortality outcomes. Also, there is controversy regarding the best cut-off point for the score. Moreover, no studies validating this score in Colombia have been carried out. Objective To assess the diagnostic performance of the Rockall score in predicting rebleeding and mortality in patients with non-varicose UGIB. Methods A prospective cohort study was conducted in patients requiring upper gastrointestinal endoscopy (UGIE) for non-varicose bleeding. The pre-and post-endoscopy Rockall scores were calculated and outcomes, including mortality, UGIB-associated mortality and in hospital rebleeding were determined at the 1 and 3-month time points. The association between the scores and these outcomes was assessed using the chi2 or the Fisher test, whereas the discrimination ability of the score was determined using the areas under the ROC curve (AUC). High discrimination ability was considered to exist in cases in which an AUC ≤0.7 with α=0.05 could be rejected. Results Overall, 177 patients were analyzed. In-hospital outcomes at 1 and 3 months were 12%, 17% and 23% for general mortality, 6%, 12% and 15% for UGIB mortality, and 19%, 30% and 37% for rebleeding. The post-endoscopy Rockall score was associated with the three outcomes at the three time points assessed, while the pre-endoscopy score was only associated with general mortality at the three time points, and rebleeding at 1 and 3 months. Regarding discrimination ability, although the AUC was greater than expected by randomness (0.5) in all cases, only one AUC ≤0.7 was rejected in the post-endoscopy score for in-hospital UGIB mortality (AUC=0.901; 95%CI: 0.845—0.958), at 1 month (AUC=0.836; 95%CI: 0.717—0.954) and at 3 months (AUC=0.869; 95%CI: 0.771—0.967), and for rebleeding at 1 month (AUC=0.793; 95%CI: 0.725—0.861) and at 3 months (AUC=0.806; 95%CI: 0.741—0.871). Conclusion An association was found between the Rockall score and rebleeding and mortality in patients with non-varicose UGIB. Only the post-endoscopy score had a high predictive ability for rebleeding and UGIB mortality.
