Severe and Recurrent Acute Kidney Injury Following Dichlorvos Exposure - A Case Report

Dichlorvos, an organophosphate compound, has the potential to cause acute kidney injury (AKI) besides its well-known neuromuscular complications. We report a case of severe-recurrent AKI that progressed to end-stage-renal-disease (ESRD) following accidental exposure to Dichlorvos. A 52-year-old male farmer presented with breathlessness after accidental exposure while spraying in the field. He required mechanical ventilation due to allergic pneumonitis and developed anuric AKI, requiring renal replacement therapy (RRT). Biopsy revealed severe acute tubulointerstitial nephritis (ATIN), which responded to steroids, and the patient became dialysis-independent by 4 weeks. Two weeks later, the patient had recurrent AKI requiring RRT. A repeat biopsy revealed severe ATIN. However, despite steroid treatment, he progressed to ESRD. Organophosphate compounds can cause renal injury with a wide spectrum of presentations, ranging from subclinical AKI to severe dialysis-dependent renal failure, which may eventually progress to end-stage renal disease.
