Final answer:
IgA nephropathy and post strep glomerulonephritis are both types of glomerulonephritis, but have different underlying causes. IgA nephropathy is an autoimmune disorder characterized by abnormal IgA antibodies depositing in the glomeruli, while post strep glomerulonephritis is caused by an immune response to Streptococcus pyogenes infection.
Step-by-step explanation:
IgA nephropathy and post strep glomerulonephritis are both types of glomerulonephritis, which is inflammation of the glomeruli in the kidneys. The main difference between the two is the underlying cause.
IgA nephropathy, also known as Berger's disease, is an autoimmune disorder in which abnormal IgA antibodies deposit in the glomeruli, leading to inflammation. This can result in blood in the urine, proteinuria, and decreased kidney function.
On the other hand, post strep glomerulonephritis is caused by an immune response to Streptococcus pyogenes infection, such as strep throat or a skin infection. Immune complexes formed during the infection can get deposited in the glomeruli, triggering inflammation and kidney damage.
