Patient's Query

Hello doctor,

I am a 26-year-old, and I had hip resurfacing surgery eight years back. I am an HLA B27 positive, even my father is also positive. I have had joint pain for the last fourteen years. Now, I wish to know that if I marry and have children will this pass on to them? What measures should I take to ensure it does not pass on to the next generation? I am at crossroads, I need to take a decision based on the reply. Please give me the solution.

Hello,

Welcome to icliniq.com.

About 80 % of people with ankylosing spondylitis have HLA B27 positive, and only 1 to 4 % of people with positive HLA B27 develop ankylosing spondylitis. That means out of 100 people with positive HLA B27, only one to four can develop ankylosing spondylitis, and 96 to 99 are normal. The chances of your children having positive HLA B27 is about 10 %. Now I do not think you should worry about your kids having ankylosing spondylitis or HLA B27.

Thank you.

Hi doctor,

Thank you for the reply.

I have been diagnosed with HLA B27 and ankylosing spondylitis. Even my father also has the same condition. And that 10 % is the additional risk compared to normal parents right?

Hi,

Welcome back to icliniq.com.

Yes, the chances of your kids having ankylosing spondylitis are 10 % each.

Same symptoms don't mean you have the same problem. Consult a doctor now!
