What is the difference between ADPKD and ARPKD?

ADPKD often causes cysts to develop only in the kidneys, while ARPKD often causes cysts to develop in the liver and the kidneys. People with either type may also develop cysts in their pancreas, spleen, large bowel, or ovaries.

What is the difference between multicystic and polycystic kidneys?

Is a multicystic dysplastic kidney the same as polycystic kidney disease? Multicystic dysplastic kidney is NOT polycystic kidney disease (ADPKD or ARPKD). Polycystic kidney disease is inherited and both kidneys have cysts (collections of fluid) and don’t work well.

How is ARPKD diagnosed?

If ARPKD is suspected, investigations and tests will be carried out – such as blood tests and scans – to confirm the diagnosis. The usual type of scan used is an ultrasound. This uses soundwaves to make images of the inside of the body. Using ultrasound, a technician or doctor can spot cysts in the kidney and liver.

What is ARPKD?

Autosomal recessive polycystic kidney disease (ARPKD) is a rare inherited childhood condition where the development of the kidneys and liver is abnormal. Over time, either one of these organs may fail.

What is the difference between CKD and PKD?

PKD is a form of chronic kidney disease (CKD) that reduces kidney function and may lead to kidney failure. PKD also can cause other complications, or problems, such as high blood pressure, cysts in the liver, and problems with blood vessels in your brain and heart.

What is the difference between multicystic ovaries and polycystic ovaries?

In polycystic ovaries there are multiple tiny cysts (immature follicles) approximately 2 – 8mm in size, usually on the periphery of an enlarged ovary. In multicystic ovaries there are many fol- licles of various sizes (from 3mm – 12mm) in a normal sized ovary.

What does Multicystic mean?

(mŭl″tē-sĭs′tĭk) Composed of or having many cysts.

What causes Arpkd?

ARPKD is caused by a DNA mutation (abnormality) in a gene called PKHD1, which produces a protein called fibrocystin that gives the kidney its structure. The faulty PKHD1 gene is responsible for small fluid-filled sacs (cysts) and scarring developing in the kidneys.

Which is more common PKD1 or PKD2?

There are two forms of autosomal dominant PKD, each caused by an abnormality in a different gene: PKD1 or PKD2. The PKD1 form is more common, accounting for 85 percent of cases, and more severe. Symptoms usually start when patients are in their 30s and the disease often progresses more rapidly to kidney failure.

When is ARPKD diagnosed?

Health care providers usually diagnose ADPKD between the ages of 30 and 50, when signs and symptoms start to appear, which is why it is sometimes called “adult PKD.” “Autosomal dominant” means you can get the PKD gene mutation, or defect, from only one parent.
