Abstract

CONTEXT: Although antithyroid drug (ATD)-induced hematopoietic damage is a significant concern, it has not been comprehensively investigated. OBJECTIVE: Our objective was to describe the clinical features of ATD-induced hematopoietic damage. DESIGN AND SETTING: This was a retrospective cohort study in Tokyo, Japan. PATIENTS: Between January 1983 and December 2002, 50,385 patients at Ito Hospital were diagnosed with Graves' disease. We retrospectively reviewed their medical, pathological, and laboratory records between January 1983 and December 2010. MAIN OUTCOME: Incidence and clinical features of ATD-induced agranulocytosis and pancytopenia were evaluated. RESULTS: Of 55 patients with documented hematopoietic damage, 50 had agranulocytosis and 5 had pancytopenia. All of them received ATD, either methimazole (n = 51) or propylthiouracil (n = 4). Median intervals between initiation of ATD therapy and the onset of agranulocytosis and pancytopenia were 69 d (range, 11-233 d) and 41 d (range, 32-97 d), respectively. Either anemia or thrombocytopenia was also documented in seven of the 50 patients with agranulocytosis. Agranulocytosis was the first manifestation of hematopoietic damage in four of the five patents with pancytopenia. Hematopoietic damage recovered with supportive measures including granulocyte colony-stimulating factor (n = 37), steroids (n = 10), and other supportive measures (n = 8) in 54 patients, whereas the remaining patient died of complications from infection. This study failed to identify the risk factors for ATD-induced hematopoietic damage. CONCLUSIONS: This study showed that ATD cause hematopoietic changes, which are occasionally severe and potentially fatal. The pathogenesis of agranulocytosis and pancytopenia might overlap, and additional studies are warranted to clarify this and to establish an optimal treatment strategy.

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.
