Abstract

CONTEXT: Radioactive iodine (RAI) is a common therapy for hyperthyroidism due to Graves' disease. A small but significant proportion of patients have recurrence of hyperthyroidism after RAI therapy. Lithium might increase RAI effectiveness by increasing RAI retention in the thyroid. However, whether lithium favorably affects the long-term outcome of RAI therapy is still a matter of argument. OBJECTIVE: The objective of the study was to compare the efficacy of RAI given with or without concomitant lithium treatment. DESIGN: This was a retrospective cohort study. SETTING: The study was conducted at a tertiary university center. PATIENTS: Six hundred fifty-one patients with newly diagnosed Graves' disease participated in the study. INTERVENTION: Two hundred ninety-eight patients were treated with RAI plus lithium (900 mg/d for 12 d) and 353 with RAI alone. MAIN OUTCOME MEASURES: Proportion of cured patients and time to achieve cure of hyperthyroidism during 1 yr of follow-up was measured. RESULTS: PATIENTS treated with RAI plus lithium had a higher cure rate (91.0%) than those treated with RAI alone (85.0%, P = 0.030). In addition, patients treated with RAI plus lithium were cured more rapidly (median 60 d) than those treated with RAI alone (median 90 d, P = 0.000). Treatment with lithium prevented the serum free T(4) increase after methimazole withdrawal and RAI therapy. Side effects after RAI therapy occurred in a subset of patients and were mild, transient, and without differences in the two groups. CONCLUSIONS: RAI combined with lithium is safe and more effective than RAI alone in the cure of hyperthyroidism due to Graves' disease.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Over several decades, reports have indicated that pretreatment with lithium reduces the activity of RAI necessary for cure of Graves' hyperthyroidism and may prevent the thyroid hormone increase seen upon ATD withdrawal.

    “Over several decades, there have been reports that pretreatment with lithium reduces the activity of RAI necessary for cure of Graves' hyperthyroidism and may prevent the thyroid hormone increase seen upon ATD withdrawal (81)(82)(83).”

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.
