I am 45. How to prevent the progression of my PKD?

Question

Hello doctor,

I am 45 and was recently diagnosed with polycystic kidney disease (PKD) after learning that my father also has the same condition. Over the past two years, my kidney function has declined from normal to a GFR of 55. I have persistent flank pain, high blood pressure requiring multiple medications, and occasional blood in my urine, which is worrying me.

My nephrologist mentioned that PKD is progressive and that I may eventually need dialysis or a kidney transplant. I am concerned about:

Are there effective treatments or medications that can slow down cyst growth and preserve kidney function?
Should my children be tested for this inherited condition, and if so, at what age?
What lifestyle changes can I adopt to protect my kidneys and delay disease progression?
How quickly does PKD usually progress to end-stage kidney disease?

Please guide me.

Thank you.

Hi,

Welcome to icliniq.com.

I have gone through your query and understand your concern.

Autosomal dominant polycystic kidney disease (ADPKD) can indeed be challenging, especially when kidney function begins to decline. Let me address your questions one by one.

Tolvaptan has been shown to slow cyst growth and preserve kidney function in eligible patients. Your nephrologist can assess if you meet the criteria, which depend on age, kidney function, and rate of decline. Strict blood pressure control is equally important, with ACE inhibitors or ARBs usually preferred. Avoid kidney-toxic drugs such as NSAIDs.

Flank pain and blood in the urine are common due to cyst rupture or infection. Persistent or recurrent symptoms should be evaluated further by your doctor, as interventions may be required.

ADPKD is inherited, and each child has a 50% chance of developing it. Testing is generally done in early adulthood, since screening children is controversial unless symptoms arise.

Reduce salt intake, avoid smoking, maintain a healthy diet and regular exercise routine, and if diabetic, ensure good sugar control.

The course of the disease varies. Some patients reach end-stage kidney disease in their forties, while others maintain function into their sixties. Careful lifestyle management and medical follow-up can slow progression and delay the need for dialysis or transplant.

I hope this helps.

Let me know if you need any further clarification or details.

Thank you.
