Abstract

Context: Bone loss and nonvertebral fractures have been reported in patients with differentiated thyroid carcinoma (DTC) undergoing thyroid-stimulating hormone (TSH) suppressive therapy. Radiological vertebral fractures (VFs) are an early and clinically crucial marker of bone fragility. Objective and Design: A cross-sectional study to evaluate the prevalence and determinants of radiological VFs in women receiving l-thyroxine (L-T4) therapy for DTC. Patients and Interventions: A total of 179 consecutive women (median age, 59 years; n = 178 postmenopausal) who had undergone thyroidectomy for DTC and were currently receiving L-T4 were evaluated for radiological VFs and bone mineral density (BMD). There were three TSH target levels [<0.5 mU/L, group 1 (n = 83); 0.5 to 1.0 mU/L, group 2 (n = 50); >1.0 mU/L, group 3 (n = 46)]. Results: VFs were found in 51 patients (28.5%), with significantly (P < 0.001) higher prevalence in group 1 (44.6%) as compared with group 2 (24.0%) and group 3 (4.3%). VF prevalence was not significantly different among patients in group 1 with normal BMD, osteopenia, or osteoporosis, whereas in groups 2 and 3, VFs were more frequent in patients with osteoporosis than in those with either osteopenia or normal BMD. In the whole population, VFs were significantly and independently associated with TSH level <1.0 mU/L; densitometric diagnosis of osteoporosis at lumbar spine, femoral neck, or total hip; age of patients; and duration of L-T4 therapy. Conclusion: The prevalence of VFs was high in women with DTC who were undergoing long-term, suppressive L-T4 therapy.

  • Overtreatment of LT4 is associated with adverse effects on bone.

    “And overtreatment of LT4 is associated with adverse effects on bone [14, 15].”
  • Women with differentiated thyroid carcinoma treated with long-term LT4 suppression therapy have a higher prevalence of vertebral fractures.

    “Mazziotti et al. [14] demonstrated that women with differentiated thyroid carcinoma treated with long-term LT4 suppression therapy have a higher prevalence of vertebral fractures.”
  • Radiological vertebral fractures in women with differentiated thyroid carcinoma receiving post-surgical levothyroxine treatment are significantly and independently associated with duration of L-T4 therapy.

    “fractures in women with differentiated thyroid carcinoma receiving post-surgical levothyroxine treatment were significantly and independently associated with TSH <1.0 mU/l, age of patients, duration of L-T4 therapy and densitometric diagnosis of osteoporosis at any skeletal site (109).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
