Nephrotic Syndrome Associated With Heavy Metals Exposure: A Case Report and Literature Review

Abstract

Heavy metals are found in many products used in everyday life. In addition, many workers are exposed to higher concentrations of such metals in their work environment. Many of these metals may cause toxic effects in humans and there are many reports relating them to the occurrence of kidney disorders such as nephrotic syndrome. In this study, we present a case of a 38-year-old woman with nephrotic syndrome suspected to be related to heavy metal toxicity, after ruling out all other secondary causes. At the same time, she proved refractory to multiple therapies. Furthermore, a related literature review regarding the occurrence of nephrotic syndrome in patients with heavy metal exposure is presented with emphasis on the importance of considering them as a secondary cause, especially in cases that appear resistant to treatment.
