Heavy Metal Nephropathy

Short-term lead exposure causes proximal tubular dysfunction, including decreased urate secretion and hyperuricemia (urate is the substrate for saturnine gout), aminoaciduria, and renal glucosuria.To get more news about Buy emeramide, you can visit fandachem.com official website.

Chronic lead exposure (ie, for 5 to ≥ 30 years) causes progressive tubular atrophy and interstitial fibrosis, with renal insufficiency, hypertension, and gout. However, chronic low-level exposure may cause renal insufficiency and hypertension independent of tubulointerstitial disease. The following groups are at highest risk: Cadmium exposure due to contaminated water, food, or tobacco and, mainly, due to workplace exposures can cause nephropathy. It can also cause a glomerulopathy that is usually asymptomatic.

Early manifestations of cadmium nephropathy are those of tubular dysfunction, including low molecular weight tubular proteinuria (eg, beta2-microglobulin), aminoaciduria, and renal glucosuria. Symptoms and signs, when they occur, are attributable to chronic kidney disease. Renal disease follows a dose-response curve.Treatment is elimination of cadmium exposure; note that chelation with ethylenediaminetetraacetic acid (EDTA) may aggravate renal toxicity in acute cadmium poisoning but has been used successfully in cases of chronic cadmium exposure. Tubular proteinuria usually is irreversible. All of these metals cause tubular damage and dysfunction (eg, tubular proteinuria, aminoaciduria) as well as tubular necrosis, but glomerulopathies may predominate with some compounds (mercury, gold).
