Studies of bisphosphonate in Therapeutics Initiative letters
Posted , 7 users are following.
A poster on another osteoporosis forum, Inspire, cited a Therapeutics Initiative: Evidence Based Drug Therapy letter focusing on bisphosphonates that I found very interesting. I also found two additional TI letters on the subject. I've not had much luck posting links on this forum, but all three letters can be found via Google; they are "A Systematic Review of the Efficacy of Bisphosphonates" (Letter 83), "Bisphosphonates: Do They Prevent or Cause Bone Fractures?" (Letter 78), and "A Systematic Review of the Harms of Bisphosphonates" (Letter 84).
The Therapeutics Initiative is funded by the BC Ministry of Health through a grant to the University of BC. Though the three letters are from 2010 and 2011, in the interval since then there do not seem to be more than a few articles analyzing the purported benefits of bisphosphonates.

One interesting point I noticed was that there was an omission from the discussion on a paper that appeared very thorough from the detail was that no mention was made of the half life.
It did include, however, that people like me should not take biphosphonates with reflux or swallowing issues.
I do have a question for you that has arisen from another thread which is as follows:
If someone has had several broken bones but only has osteopenia but also taking drugs that affect bone density should they be given either biphosphonates or Prolia?
I wonder if there is something else causing the breaks as osteopenia would not usually warrant taking any of the drugs?
During the reading I have also noticed that some people have no improvement after taking biphosphonates.
I will keep reading and looking for the other two letters you mention.

Your observation that bisphosphonates lead to no improvement in some people is, I think, well supported by the evidence. Of the articles I've come across (including the three letters that are the subject of this post), the phenomenon of the high number of patients needed to treat in order to confer any benefit is cited.
Patients posting on the merits of the osteoporosis drugs, as well as many authors of articles, often seem fixated on the concept of the relative "rarity" of catastrophic side-effects ... an argument that is probably doomed to a stalemate until further data accumulate. However, there seldom seems to be scrutiny given to the frequency and extent to which these drugs may or may not actually help ... likely because there's no way to measure benefit in terms of actual fracture prevention -- how can one quantify an event that hasn't happened? -- but instead having to rely on the surrogate outcome of increased bone density (which doesn't necessarily equate with bone strength).

Also, some have been prescribed drugs without even having had a bone density test.
Why do some people with quite severe osteoporosis fall yet do not break bones whilst others fall and break bones multiple times but have either no issues with their bones or only mild osteopenia?
I am thinking that this whole bone business is more complicated than a number given as a t score!
I have picked up on the bone strength vs bone density too which I think is explaining some of the anomalies I just mentioned.
We may not be doctors but we are researching and finding out information that does back our decision not to rush into taking any of the drugs.

My understanding of the osteopenia/porosis problem is that osteopenia is just a name given to the early form of osteoporosis and that only T-score levels differentiate between the two variations. So I can see the logic in giving osteoporosis drugs to patients with osteopenia in an attempt to interfere with the progress of and possible ward off the full blown disease. I'm not sure that I like the application of this sort of logic since without regular scans to monitor the progress of the disease, there seems to no way to know at what stage you are at, especially since the progress is not linear and constant. (and probably can be affected by other factors but I'n not sure about this). I do know that some patients (my daughter for instance) have had osteopenia for many years and it would not have been sensible to have her take osteoporosis drugs for all that time, particularly with all the side effects. Presumably the relationship between bone density and bone strength is affected by the way that calcium has been previously deposited and could be affected by the 'toughness' of the bone which is related to its susceptability to crack propagation. Data on this seems to be in short supply but I think that this is worth a little spare-time investigation (It could also be pointless!)

As the bones are measured again a 30 year olds and few are as lucky as my husband to have bones that good then some wear and tear must be expected.
Dr reaffirmed my belief that the drugs are not the best or only choice to deal with osteoporosis. She also offers other ways to attack the health issue of our bones.
I know you have chosen the AA route Aristotle and that is your choice.
As far as I know most doctors have stopped prescribing the drugs for osteopenia.
It is always good to hear your opinions Aristotle and it is fine if we do agree on everything as this is a very contentious subject.

Surprisingly, we do agree on most of the drug items. If I had been more aware of what was as you say, a contentious set of drugs I may not have been so (complacently) keen to trust my doctor without first doing the checking up like I now do. Having now been taking AA for around four months, I shall at least continue until the year is up and then hopefully have a scan and see what has happened and make my ongoing decision then. At the moment, most of the observable side-effects seem to have disappeared and the only remaining evidence is that I have thicker nails and my Lichen Planus is only slowly going back into remission. I wasn't aware but am pleased that most doctors have ceased prescribing AA for Osteopenia.
I ordered two books but they are still in the post somewhere. I just hope that they are as good as the bits that I've already seen.
Thanks for your comments. All the best.

I do not know why I hesitated taking AA to begin with before I even had done much in the way of reading My gut just said not to!
Then I thought about my difficulty swallowing sometimes and choking occasionally. From there I progressed to further reasons from my oral surgeon and general exploring on the Internet.
Thanks for your comments and interaction. I do appreciate it.

What were your T-scores and is your doctor really justified in using scare tactics. If you haven't had fractures and it's still at the osteopenia stage, there's a good chance that you are not as bad as fear would make you think. If your T-scores aren't too bad, there os probably no need to rush into AA and possible nasty side effects. The choice is obviously yours but there's a lot of sense in the papers by Dr and I'm hoping that later on in the year that I'll be able to change to a more natural form of protection.
Hope that all goes well for you.

I couldn't understand why they wouldn't tell me my t-score at first. I'm in a high risk category because I take prednisone for PMR, and I had a broken bone two years ago, although I question the description of "fragility" fracture. Now there are two things I can't do anything about. I can't not have had a broken leg two years ago. I can't not be taking prednisone. But I can do something to strengthen my bones. And I'm am mystified as to why they would not, without my insistence, tell me that third part of the puzzle. I mean, if I have risks for heart disease or diabetes they are unlikely to keep one of the risk factors hidden from me, particularly one I can actually do something about!

You have a right to your results and full information and it is hard to credit that would happen in this day and age anywhere in the world!

They don't sell those injuries as being anything to do with osteoporosis.
I have fallen down a very long staircase on a cruise. I fell so fast my husband could not catch me. Nothing was broken but I sustained severe injuries and needed shoulder surgery. All four tendons were ripped off the bone. Nobody mentioned osteoporosis or how amazing that nothing was broken!

I don't mind if you ignore the next query, but what is PMR?
Thanks for chatting, it's nice to know there are persons who still believe that communication is a great help at passing information and opinions. I still learn loads of new things every day, just hope that the memory holds out!

Professor Bauer is a practicing MD as well as doing teaching and research.
Vast majority of his research over 30 years has been on osteoporosis.

I'm good at jumping in with both feet and I usually learn loads on the way, it's just unfortunate that it's too late to be useful by the time that I've digested things.
. You have my good wishes and thanks for replying.

I concocted a link for the presentation and have sent it to you as a test in a private message. It would be nice to know if this system works properly.

I managed to view and listen to the uTube Osteoporosis presentation and was quite impressed withe quantity of data that had been collated and arranged to give a coherent answer. If I read it correctly, it seemed that the end product was a recommendation that if you have a high T-score or a previous fracture, you should take AA for five years and then lay off it for five years. I'm not entirely convinced and now one of the books that I ordered has arrived - The Whole Body Approach To Osteoporosis. More reading, hopefully interesting. Not until after I've cut the grass!

Thank you for your input. I know we have not always agreed but that is okay as it shows different perspectives.
I wish you well in the future and hope you receive all the support you need.
