Resumen
Introducción: la nefropatía mesoamericana es una nefropatía túbulo-intersticial cuya etiología aún se desconoce. Sin embargo, se han descrito casos clínicos similares a esta en otras regiones geográficamente distantes y étnicamente diversas. Aun así, todos tienen un factor común: la intensidad del calor y el trabajo físico rural. Objetivo: estudiar si esta entidad podría presentarse entre trabajadores rurales de una región no mesoamericana con condiciones climáticas y laborales similares, en el campo del Caribe colombiano y considerar cuánto podría pesar en su patogénesis la deshidratación repetitiva. Materiales y metodología: se realizó un estudio observacional, basado en un trabajo de campo en una finca de Sitio Nuevo (Colombia) en 28 voluntarios trabajadores rurales (arrozales), a quienes se les tomó peso, presión arterial y muestras de sangre y orina para medir electrolitos y osmolaridad, en 2 momentos del día (mañana y tarde). Resultados: de los 28 trabajadores jóvenes evaluados, 5 (18 %) presentaron aumento significativo de la creatinina sérica durante el día (0,8±0,15 vs 1,2±0,17, p<0,001). El volumen de agua ingerido por los trabajadores fue muy variable (2.861 ± 1.591 cc). Hubo un aumento significativo en los valores de sodio sérico (p<0,001) y osmolaridad urinaria (p=0,01) entre los valores de la mañana y la tarde en estos 5 pacientes. Conclusión: el dieciocho por ciento de los trabajadores evaluados desarrolló parámetros compatibles con daño renal agudo y deshidratación durante la jornada laboral en el campo del Caribe colombiano.
Introduction: Mesoamerican nephropathy is a tubule-interstitial nephropathy whose etiology is still unknown. However, clinical cases like Mesoamerican nephropathy have been described in other geographically distant and ethnically diverse regions. Still, they all have a common factor: the intensity of heat and rural physical labor. Objective: To study whether this entity could occur among rural workers in a non-Mesoamerican region with similar climatic and working conditions, in the Colombian Caribbean countryside, and to consider how much repetitive dehydration could weigh in its pathogenesis. Methodology: An observational study was carried out, based on field work in a farm in Sitio Nuevo (Colombia) with 28 rural worker volunteers (rice fields), who were measured for weight, blood pressure, and blood and urine samples to measure electrolytes and osmolarity, at 2 times of the day (morning and evening). Results: Of the 28 young men workers evaluated, 5 (18 %) presented a significant increase in serum creatinine during the day (0.8±0.15 vs 1.2±0.17, p<0.001). The volume of water ingested by the workers was highly variable (2,861 ± 1,591 cc). There was a significant increase in serum sodium (p<0.001), and urinary osmolarity (p=0.01) values between morning and afternoon values in these 5 patients. Conclusions: Eighteen percent (18 %) of the workers evaluated developed parameters compatible with acute kidney injury and dehydration during the workday in the Colombian Caribbean countryside.
