Mixed results 1 year after Forteo: What are your thoughts?
Hello all,
Recently I've pondering with my dexa results 1 year post Forteo treatment. There are so many involved factors which made it hard to pinpoint whats the main culprit for the negative part of the results.
Background and/Hx: 61yo diagnosed with op summer of 2022, no known fractures. No prior treatment of op including HRT. Started Forteo Sept. 2022. Comorbidities include mild cvd with hyperlipidemia which is controlled with a small dose of crestor; asymptomatic mild GERD w/o treatment and borderline pre-diabetic managed via lifestyle and diet.
At 13 mo post Forteo, Dexa results after vs before treatment are as follows:
L1-L4 spine: avg Tscore -3.1 vs -3.4, with a 4.9% bmd improvement. Each sub level also shows improvements;
Hip: avg Tscore -2.2 vs -1.8, with a -7.6% bmd decreasing!
TBS L1-L4: 1.318 vs 1.264, a 4.3% improvement.
P1NP is elevated in 400+
While I'm very happy with the spine and TBS improvements, the results for the hip/femoral region is very alarming, to say the least.
Has anyone of you experienced or heard of such discrepancy in results that Forteo would produce?
My immediate instinct is that I didn't exercise enough. I was only doing weigh/strength training with free weights consistently, targeting upper, lower and core, 15-20 reps x3-4, twice per week; with some walking and wearing weighted vest/backpack. Never thought about loading hip bones (but, I do quite a bit squats). After some reading I realized maybe I also need to increase amount of quality protein a bit. What's a good protein intake per kg body weight per day, in your opinion?
Anyhow, juggling among drug treatment choices as well as optimal nutrition, supplements and exercise is not an easy task.
Any opinions and suggestions are truly appreciated. The collective experiences and knowledge from patients are powerful!
UPDATE: March 30, 2024
My dexa scan 13 months post forteo therapy was reevaluated later and was found there were technical errors involved. My endo concluded that my femur neck and hip at both sides didn't have any significant change afterall. This is a good news to me. Although I wish I had some positive improvements at femur necks and hips, the results are within expectations. Thanks a lot to those who read my story. mayblin
Interested in more discussions like this? Go to the Osteoporosis & Bone Health Support Group.
Having either very low or very high HLD carries health risks. Around 70 is good, but there is something like a U shaped curve where certain risks increase at both ends of the spectrum. So it still is good, but only up to a point, so higher is not better. Many doctors used to think that high total cholesterol was OK as long as HDL was high, Not any more.
Thank you for your kind reply! Although I'm aware of several different bisphosphonates exist, I don't know the rational behind the selection process. My doctor is planning reclast for me. I'm trying to explore which one would be the best candidate to get off of, or, in case a future round(s) of anabolic use are in the cards.
I was thinking out loud in a reply to @windyshores couple days ago, regarding the use of solution form of alendronate for those of us who have mild gerd or stomach issues. If the idea is viable, then other issues like generic equivalency/bioequevalency needs to be figured out. Other bisphosphonates could be potential candidates too. It's just so time consuming and really exhausting to figure these things out.
Dr. Mccormick recommends Actonel to you instead of fosamax, this give me am impression that he favors these to reclast. Do you happen to know his rational of such suggestion?
McCormick recommends Reclast, but Actonel or Fosamax can be used if a person cannot do Reclast. At least in my discussions with him.
I see. So it seems that reclast is the drug of choice as a lock in agent, unless contraindicated?
Thanks a lot, windyshores!
I will stop Forteo on July 21,2024. At that time I need to have a Reclast infusion to hold any bone gains in place. My oral surgeon would prefer me to take Fosomax instead of Reclast, because of complications with the jaw bone should I need invasive dental work in the future. Are there any studies comparing the efficacy of Reclast vs Fosomax in holding bone gains after Forteo?
@janflute I have read that Reclast is more potent but if Fosamax is the only one tolerable, it can help. I would ask your doctor because dentists don't seem to know that much about these meds and are afraid of all of them. My dentist was concerned about Tymlos which doesn't even affect teeth!
@mayblin I don't think lack of exercise explains your situation. I hope you will do Forteo for two years and have a DEXA then. It is still early to do a DEXA. The loss in your hip is a mystery. What does your doctor say?
For those who are nervous about Reclast, you could ask for a test dose of 20% to see how you react. Then have another infusion at a dose of your choice in 3 months. Again, discuss with a doc!
Thank you. I will talk to Dr. Mannstadt about this when I see him in May. I would want to take the drug that held the bones in place the best. 😘
janflute, in a head to head clinical trial both drugs prevented spinal fracture in equal measure. Reclast was more effective at preventing overall fracture. Reclast is adherent to the bone for longer so would make a the PTH drugs less effective it you decide on a second go with Forteo or Teriparatide.
@janflute if you don't have a health condition that concerns your doc about Reclast, they will probably suggest kidney testing, then hydration day before, day of and day after, and a slow infusion. You can also medicate beforehand. Many women I know have absolutely no side effects, but many who do have side effects post here. My test dose is because I have afib, kidney disease and med reactions and my doc wants the test dose for those reasons. Not sure your doc will prescribe a test dose without a reason-? My nephrologist is very concerned for my kidneys with Reclast and communicated that to my endo.
I would think that switching to Evenity might be a good possibility if the Forteo is truly not working or even making things worse. Is it possible the technician made an error?!
