Case Report: Silicosis and IgA nephropathy, an exceptional association

A 57-year-old male who had been working in masonry for 33 years was hospitalized for renal function decline associated with exertional dyspnea. He presented with hypertension and limb edema. Urinalysis revealed an active urine sediment with glomerular proteinuria at 1.5 g/24h and the renal biopsy identified mesangial IgA Nephropathy. Chest tomography scans showed signs of silicosis. The patient received Angiotensin-Converting Enzyme Inhibitors with stable renal function. To our knowledge, the association of silicosis-IgA nephropathy has rarely been reported in the literature. This case highlights the effect of chronic exposure to silica dust and its association with both silica and renal disease.
