Hypophosphatemia & oncogenic osteomalacia
Posted , 27 users are following.
My condition, hypophosphatemia and oncogenic osteomalcia started about 3 years ago, however, was not diagnosed until six months ago. It started very gradually with body stiffness that over time worsened to bone and muscle pain and weakness. Was examined by all kinds of specialists who really didn't know why I had so much pain just walking, sitting and getting in and out of bed. My Rhematologist had been very puzzeled by some of my blood test results concerning alkaline phosphates being 3 times as high as they should be. Vitamin D testing showed I was severely deficient. Subsequent examination, blood tests and bone biopsy by an Endocrinologist indicated oncogenic osteomalacia and hypophosphatemia being caused by a tumour somewhere in my body. The tumour gives off something that causes my Vitamin D and phosphates to become deficient in turn causing the bone pain and muscle weakness. Subsequent CT scans and PET scan have not located the tumour. Am taking medications that are helping somewhat. Want to communicate with someone who has this condition or recovered from it. Have questions about medications, rehabilitation and generally knowing about their experience.

The tumour produces FGF23 which, when it gets round to the kidneys stops them from producing Calcitriol. Calcitriol is the substance which joins calcium and phosphates to make bone. Without it the bone does not form properly and the phosphates pass out in your urine. Taking phosphate supplements helps replace that which is lost and taking Calcitriol helps to make new, stronger bone.
i have been taking both for several years and have recently been told that my bone is now normal. As they are unable to find the tumour, and are unlikely to, I will have to take them for the rest of my life.
i hope this all helps. Please remember, this is just my understanding of how it works. If anyone knows better please let me know as I am keen to learn more.

i am so sorry your husband and you are going through this. I can empathise as I broke both hips. In fact, I have had over 20 fractures and am now having spinal problems.
if you read my posts you will see my understanding of this problem. It has taken several years of taking calcitriol and phosphate supplements but my bones are now back to normal density.
Please don't give up hope as there are several of us out there who are sharing similar experiences, you are not alone.
i wish you both the best of luck.

My doctors are in the Chicago area too. I have been to Northwestern, NorthShore and Lutheran General. They have been helpful, but so far, I have not seen anyone with a clinical or research interest in oncogenic osteomalacia. I am wondering what your experience has been. All the best! ( :

I found the Tumor Induced Osteomalacia TIO Facebook page. It looks great! I really like the cover page.

I am posting on this as my pop has been suffering for three years from what sounds like the exact same condition!
We are in Tasmania, Australia and so far the closest we've had to answers has been one doctor telling him he has hypophosphatemic rickets. But has done nothing to help treat him except prescribe painkillers.
His vitamin D, calcium and phosphate levels are all low and he takes calcium and vitamin D supplements but does anyone else know what to suggest?
He's also had PET scans, blood texts, xrays but nothing but fractures in his feet.
Please help with how we can help him!
