introduction : clozapine is the first effective antipsychotic drug with the least extra pyramidal side effects and more agranulocytosis than other standard neuroleptics. granolocytopenia or agranulocytosis occurs in 1 to 2 percent of all patients treated with clozapine. agranulocytosis due to clozapine is a fatal disorder that requires immediate clinical intervention.   method : this paper repo...

Use of the iron chelator deferiprone for treatment of iron overload in thalassemia patients is associated with concerns over agranulocytosis, which requires weekly absolute neutrophil counts (ANC). Here, we analyze all episodes of agranulocytosis (n = 161) and neutropenia (n = 250) during deferiprone use in clinical trials (CT) and postmarketing surveillance programs (PMSP). Rates of agranulocy...

Agranulocytosis is an extremely serious, although rare, adverse effect of antithyroid drugs (ATDs), including methimazole (MMI) and propylthiouracil (PTU), in children and adolescents. There are few reports about the characteristics of ATD-induced agranulocytosis in Japanese children and adolescents. This report presents the cases of three girls with ATD-induced agranulocytosis and a retrospect...

BACKGROUND Agranulocytosis is a life-threatening disorder, often caused by drugs. Incidences or risks of drug-induced agranulocytosis are not well known, since it is rare. METHODS To determine the risk of drug-associated agranulocytosis as a reason for admission to Dutch hospitals, we performed a population-based case-cohort study. Hospital discharge data came from the Dutch Centre for Health...

Agranulocytosis is a rare and critical adverse effect of antithyroid drugs (ATD). The occurrence of agranulocytosis in continuous ATD treatment patients is well known; however, a case of ATD agranulocytosis occurring following the discontinuation of methimazole (MMI) treatment is not a usual situation. We herein describe a case of a 41-year-old woman who was previously administered methimazole ...

Hematological abnormalities are frequently encountered during treatment with antipsychotic drugs. Most of these mild and no clinical significance, but in a small minority patients, hazardous, potentially life-threatening hematological effects, including leucopenia, neutropenia, agranulocytosis, thrombocytopenia, anaemia , leucocytosis, thrombocytosis, eosinophilia altered platelet function. (1)...

Granulocyte colony-stimulating factor (G-CSF) levels in serum were determined by a highly-sensitive chemiluminescent enzyme immunoassay (limit of detection, 0.5 pg/ml) in 54 patients with Graves' disease including 6 patients complicated with methimazole-induced agranulocytosis. Serum G-CSF levels in patients with Graves' disease were not different from normal subjects and did not correlate with...

Antithyroid drugs are widely used to treat hyperthyroidism, especially Graves' disease, but they tend to cause agranulocytosis, which increases the mortality rate. Granulocyte colony-stimulating factor decreases the duration of recovery from agranulocytosis. We retrospectively studied cases of antithyroid drug-induced agranulocytosis over the past 10 years in a northern Taiwan medical center. A...

Agranulocytosis is a rare adverse effect of methimazole. The usual duration of treatment prior to the onset of agranulocytosis is approximately 1 to 4 months, and can be as long as 1 year. Agranulocytosis together with hepatotoxicity is an extremely rare idiosyncratic side effect of methimazole treatment. We present an unprecedented case of a Grave's disease patient who showed a strong reaction...
