Abstract

Several cases of glomerular disease have been associated to thyroid diseases. The most frequent lesion described is membranous glomerulopathy, presented as a nephrotic syndrome. Here we report a 67-year-old man who developed a nephrotic syndrome accompanied by rapid derangement of renal function shortly after the onset of a primary hypothyroidism due to autoimmune thyroiditis. High titers of circulating anti-thyroglobulin and anti-microsomal thyroid antigen antibodies were detected. Serum levels of C3 and C4 fractions of complement were markedly decreased. Renal biopsy showed a membranoproliferative glomerulonephritis with severe mesangial proliferation, a type of glomerular involvement non-described previously in the literature, in relation with thyroid diseases. Four boluses of intravenous steroids were administered, followed by oral prednisone for three months. A dramatic recovery of renal function, together with normalization of urinary sediment, proteinuria decrease and normalization of serum complement were observed. Three years later, the patient suffered from a similar event, with a positive response to steroids again. One year later, the patient had a new recurrence and was treated with mycophenolate mofetil , improvin...Continue Reading

Autoimmune Thyroiditis

Autoimmune thyroiditis is an inflammatory disease of thyroid gland due to autoimmune responses leading to lymphocytic infiltration of the gland. It is characterized by the presence of circulating thyroid antigen-specific T-cells and thyroid autoantibodies. Discover the latest research on autoimmune thyroiditis here.

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
