How is amyloid nephropathy diagnosed?

The diagnosis of amyloidosis requires histologic demonstration of amyloid deposits. This usually is accomplished by staining with Congo red dye. Congo red–stained amyloid has an orange-red appearance under light microscopy and produces apple-green birefringence under polarized light.

What are the warning signs of amyloidosis?

Signs and symptoms of amyloidosis may include:

Swelling of your ankles and legs.
Severe fatigue and weakness.
Shortness of breath with minimal exertion.
Unable to lie flat in bed due to shortness of breath.
Numbness, tingling or pain in your hands or feet, especially pain in your wrist (carpal tunnel syndrome)

How is amyloid nephropathy treated?

Medication therapy. The goal of medication therapy, including chemotherapy, is to reduce amyloid protein levels in the blood.
Stem cell transplant. A stem cell transplant is a procedure that replaces a patient’s damaged stem cells with healthy ones.
Treating other conditions.

What are the signs and symptoms of AA amyloidosis?

AA amyloidosis can affect many organs, resulting in the following signs and symptoms: Signs and symptoms indicating the kidneys are affected include: Swelling of the feet or legs. Excessive bubbles in the urine (foamy/frothy urine)

What happens if you have amyloidosis in your kidneys?

Amyloid in the kidney can cause leakage of protein in the urine resulting in a low blood protein level and swelling of legs or face. This syndrome is known as “Nephrotic Syndrome”. Also, the kidneys normally filter and clean the blood, getting rid of the body’s natural waste products as urine.

How is amyloidosis a protein misfolding disorder?

Amyloidosis is a “protein misfolding disorder.” Normally, proteins in the bloodstream are removed and/or recycled once they have completed their job. In amyloidosis, however, a protein can change shape (or “misfold”) and can no longer be cleared.

What are the symptoms of amyloidosis and carpal tunnel?

pain, stiffness, and fluid in the joints. abnormal, fluid-containing sacs, called cysts, in some bones. carpal tunnel syndrome, caused by unusual buildup of amyloid proteins in the wrists. The symptoms of carpal tunnel syndrome include numbness or tingling, sometimes associated with muscle weakness, in the fingers and hands.
