Insuficiencia renal aguda por picadura de hormigas del palo santo (pseudomyrmex spp) / Acute renal failure due to the bite of ants of palo santo (pseudomyrmex spp)

RESUMEN

La Insuficiencia Renal Aguda (IRA) es una complicación inusual de la picadura por hormigas secundaria a un daño tóxico isquémico con Necrosis Tubular Aguda. Los 2 pacientes presentados fueron transferidos del trópico Cochabambino al Hospital Clínico Viedma, experimentaron una reacción alérgica, hemólisis intravascular, rabdomiólisis e IRA posterior a un masivo ataque de las hormigas que habitan en el tronco del "Palo Santo" al que fueron atados por varias horas. Se dispone de pocos reportes acerca del compromiso renal en estos casos, así como de los mecanismos patogénicos implicados. Gracias al apoyo dialítico oportuno los pacientes mejoraron su condición clínica recuperando ambos la función renal en el lapso de 2 semanas de iniciada la hemodiálisis.

ABSTRACT

The two patients presented were transferred from the tropic of Cochabamba state to the Viedma Hospital, they have experienced an allergic reaction, intravascular hemolysis, rhabdomyolysis and ARI caused by the massive attack of ants that inhabit the trunk of the "Palo Santo" where they were tied by several hours. Few reports are known about the affectedness of the kidney organ, as well as the implied pathogenic mechanisms. The patients improved their clinical condition thanks to the opportune support; both recovered the kidney function after 2 weeks from the initiated hemodialysis.
