The infection may move up the system to the bladder or to the kidneys. Men most at risk for a UTI include: 1  Those with abnormalities of the urinary tract, such as kidney stones or an enlarged prostate.  Those who have a catheter or tube placed in the bladder.
Familial (hereditary) amyloidosis is a genetic form passed down in families that often affects nerves and kidneys. Secondary amyloidosis (AA) develops along with a chronic infectious or inflammatory disease, such as tuberculosis or rheumatoid arthritis.
The specific cause of rheumatoid arthritis has yet to be identified despite decades of medical research. While we donât know specifically what causes rheumatoid arthritis, we do know that it is the result of an autoimmune disorder. An autoimmune disorder occurs when immune cells begin to attack the body. In the case of rheumatoid arthritis, the body attacks its own healthy joint tissue called the synovium. The synovium is what produces a clear liquid substance known as synovial fluid. This fluid lubricates healthy joints and gives cartilage and bones the nourishment required to remain effective and mobile.
