  • My brother has been diagnosed with amyloidosis. What is the usual course of treatment?

    There are mainly 2 kinds of amyloidosis, AL and AA amyloidosis. Treatment depends on the cause of the abnormal protein production, known as amyloid fibrils In AL amylodosis, therapy is aimed at the underlying plasma cell dyscrasias. In AA amyloidosis, therapy is aimed at the underlying inflammatory or infectious etiology. As your brother is very young, I’m not sure whether he has amyloidosis secondary to Familial Mediterranean Fever (FMF). Your brother needs further studies including tissue biopsy. Hope this will help you. READ MORE

Most common systemic disease-causing nephrotic syndrome are: diabetes, hepatitis B, hep C, lupus, HIV, amyloidosis, etc. Your doctor will be doing blood work and a urine test and, if needed, will be doing a kidney biopsy for the diagnosis.

  • What is the affect of hypertension on kidneys?

    Hypertension can be a causative factor (hypertensive nephroscletodis) or a contributory factor in chronic kidney disease. In addition to the level of blood pressure, other individual factors are involved. As an example, black patients have an approximate eight fold elevation in the risk of hypertension-induced end-stage renal disease. This high risk may persist even with good bp control. Also, it is advisable to look for other reasons for hypertension like polycystic kidney disease, as there are kidney problems in the family also. Please check with her physician.
