Interstitial Nephritis Presenting as Acute Kidney Injury Following Ingestion of Alternative Medicine Containing Lead: A Case Report

Abstract

Introduction: Some studies have shown that patients consuming alternate medicine can suffer from complications like acute kidney injury (AKI) due to heavy metal poisoning. The use of traditional ayurvedic herbal remedies may be difficult to identify as a source of toxicity, especially if the treating doctor is not aware of this habit, unless a detailed history is taken. In this report, we describe a patient who had consumed ayurvedic supplements for treating fever and abdominal pain and presented to our emergency department (ED) with AKI. Case presentation: A 24-year-old male presented to the ED with complaints of abdominal pain, fever and loose stools. His blood tests revealed AKI and he was started on emergency hemodialysis. His renal function improved after only one cycle of dialysis and he was discharged in a stable condition. Conclusion: Acute lead toxicity should be suspected in patients with abdominal and neurological dysfunction who have a history of chronic ayurvedic medicine intake and thus should be promptly treated. Physicians should rule out potential toxicity from these supplements and have a heightened level of suspicion for lead toxicity in patients presenting with abdominal pain and AKI without any obvious cause.
