Rheumatoid arthritis is an autoimmune disease where the immune system fails to function well and attacks the joints of the body by mistake. Kidney damage is a complication of rheumatoid arthritis.What are the causes and symptoms of kidney disease in rheumatoid arthritis?
Causes of Kidney Disease in rheumatoid arthritis
A variety of renal disorders can occur in patients with rheumatoid arthritis, due to the underlying disease, to drugs used to treat the inflammatory process, and to concurrent renal disease unrelated to rheumatoid arthritis.
Rheumatoid arthritis is an autoimmune disorder.The abnormal activity of immune system not only can affect the joint,but also attacks other body parts including kidneys.The abnormal activity of immune system can cause inflammation in kidneys,resulting in progressive renal function decline.The most common disorders associated with rheumatoid arthritis are Membranous Nephropathy, secondary amyloidosis, a focal, mesangial proliferative glomerulonephritis, rheumatoid vasculitis etc.
Symptoms of kidney disease in rheumatoid arthritis
Proteinuria refers to loss of excess protein in urine.Hematuria refers to presence of red blood cells in urine.Proteinuria and hematuria are common signs of rheumatoid arthritis induced kidney disease.As the tiny blood vessels in kidneys are impaired and fail to keep protein and red blood cells retain in body,thus resulting in proteinuria.
Swelling occurs as retention of fluids in body.As the kidneys are not functioning normally,extra fluid can not be discharged out of body,thus resulting in swelling.
High blood pressure
Rheumatoid arthritis induced kidney disease can cause high blood pressure.In return,high blood pressure is a significant risk in worsening renal function.One cause is high building up of extra fluid in body. Another cause is that the kidneys fail to produce a hormone which can regulate blood pressure.
Rheumatoid arthritis induced kidney disease may progress into Kidney Failure if left untreated.Therefore,it is important for the patients to seek for aggressive treatment early. You can chat with our medical profession to get more treatment information.
