- QUESTION: My brother has been told he has a disease that causes cysts to form
- in the kidney. The doctor also told him it was inherited and therefore I
- might have it as well. Have you ever heard of this kind of illness, and would
- you share some of your knowledge with me? Thank you very much.

- ANSWER: I believe your brother has been diagnosed with a disease of the
- kidney known as "Autosomal dominant polycystic kidney disease" (ADPKD), (also
- known as adult polycystic renal disease). ADPKD is a relatively common
- familial disorder, affecting approximately one in 500 Americans, and the
- possibility that you too may have the same condition without realizing it does
- exist, especially if you are younger than he is. Patients with the dominant
- gene have an almost 100 percent chance of developing the disease by age 80.
- In individuals with ADPKD, the kidneys are abnormal from birth. Small
- cysts are present in the newborn and gradually grow larger with age. As the
- cysts enlarge, they press on the neighboring kidney tissues, reducing the
- blood flow to these cells. The combination of increased pressure and
- diminished circulation causes these cells to atrophy and die. This reduces
- the ability of the kidneys to perform their functions. But this is a slow
- process, often proceeding without causing any obvious symptoms, and in some
- cases can go undiagnosed throughout the patient's entire life.
- Most patients show no symptoms until their mid-twenties or early middle
- adulthood. Because screening of asymptomatic individuals in families with
- known ADPKD is recommended, you might wish to consult with your own doctor.
- Ultrasound examinations, followed by additional studies in positive cases,
- frequently provides a diagnosis before the onset of symptoms. Some of the
- symptoms that may be provoked by ADPKD are; blood in the urine, renal colic
- due to obstructing clots, pyelonephritis, hypertension, and in advanced
- stages, palpable abdominal masses, chronic renal failure with the nephrotic
- syndrome, weight loss, or subarachnoid hemorrhage from associated intracranial
- aneurysms. Since chronic renal failure often occurs within ten years of the
- onset of symptoms, you would be well advised to start your own investigations
- now.
