Exposición humana al mercurio y sus efectos hematológicos: una revisión sistemática

Autoría SCIMAGO INSTITUTIONS RANKINGS

El mercurio es un metal que se puede encontrar de forma natural en el ambiente y mediante fuentes antropogénicas. Es altamente tóxico para los ecosistemas y seres vivos. Entre otras, la mayor parte de la exposición humana, proviene de la ingestión de pescado contaminado, liberación de gases de amalgamas dentales o exposición ocupacional (p.ej. extracción de oro). Vastas poblaciones están expuestas al mercurio, convirtiéndolo en un asunto muy importante desde la perspectiva de la salud pública. Los efectos adversos para la salud se observan comúnmente en el sistema nervioso, pero cada órgano es un objetivo potencial, como la médula ósea. El objetivo principal del estudio fue evaluar las evidencias disponibles sobre la exposición humana al mercurio y sus efectos hematológicos. Se realizó una estrategia de búsqueda, incluyendo términos clave (palabras-clave, palabras del texto y equivalentes), se consultaron 2 registros de trabajos finales de máster y tesis de doctorado (Fiocruz/ARCA y Universidad de São Paulo) y 4 bases de datos electrónicas diferentes: BVS/LILACS, MEDLINE/PubMed, Scopus y TOXLINE/NIH, para artículos publicados desde el año 1950, hasta febrero de 2018. No hubo restricciones de lengua y se usó la herramienta (EPHPP) para evaluar la calidad de los estudios incluidos. De acuerdo con los criterios preestablecidos, se recopilaron 80 estudios, todos observacionales (48 informes de casos, 24 estudios transversales, 6 series de casos, y 2 cohortes), que comprendieron a 9.284 personas. A pesar de que la mayoría de los expuestos (6.012) tenían un recuento normal de células sanguíneas y los efectos hematológicos del mercurio no parecían muy comunes (1.914 casos: 14 severos y 29 muertes), tres estudios informaron de la asociación (β) para anemia, linfopenia, neutrofilia y basofilia. Concluimos que la información recabada indicaba los efectos hematotóxicos del mercurio, algunos de los cuales pueden ser muy serios e incluso fatales.
