Preoperative preparation of the hyperthyroid patient for thyroidectomy is imperative to avoid perioperative complications due to severe thyrotoxicosis. The mainstay of preparation is the administration of anti-thyroid drugs (ATD). When ATDs cause adverse reactions, an alternative regimen to prepare the patient for definitive management is crucial. We present the case of a 35-year-old Filipino female with Graves’ disease who developed methimazole-induced agranulocytosis. She refused to undergo radioactive iodine (RAI) therapy. She was admitted for thyroidectomy with elevated thyroid hormone levels. She was rapidly prepared for thyroidectomy using high-dose steroid, beta-adrenergic blocker, propylthiouracil (PTU) and Lugol’s solution. The patient’s free thyroxine level decreased after 8 days of treatment, without complications. She then underwent an uneventful subtotal thyroidectomy. In conditions with very limited options, although contraindicated, administration of another ATD may be the last alternative for patients who developed agranulocytosis.

A 51-year-old Caucasian male developed Graves’ thyrotoxicosis following long-standing treatment for hypothyroidism. After a short period of treatment with carbimazole, he developed agranulocytosis and required total thyroidectomy. In this relevant case report, we review several pathogenetic mechanisms that explain the transformation of autoimmune hypothyroidism into Graves’ disease and the possible approaches to the management of agranulocytosis secondary to antithyroid medications. Further studies are required to determine the best way to manage severe thyrotoxicosis when agranulocytosis develops due to antithyroid medications.

Methimazole is a widely used and generally well-tolerated antithyroid agent. Adverse reactions occur in 1~5% of patients taking methimazole medication, but these are most commonly transient, benign leukopenia and a skin rash. Severe cholestatic jaundice, combined with agranulocytosis, has been known as a rare complication. Herein, a case of methimazole induced cholestatic jaundice, with agranulocytosis, is reported.

Antipsychotic-induced agranulocytosis is a significant side effect that is known to occur with most of the antipsychotic medications. It usually resolves once the medications are stopped and patients are able to be switched over to another antipsychotic medication. Lurasidone has not been reported to cause leukopenia and neutropenia. This case report is of a patient with a past history of risperidone induced-aganulocytosis developing dose related leukopenia and neutropenia with lurasidone.

Levamisole has been used for nephrotic syndrome due to its immunostimulating, immunomodulating, and steroid-sparing effects. Agranulocytosis, a serious side effect of levamisole, was rare and mostly associated with autoimmune disease, neoplastic disease and HLA B27 except one case in a nephrotic syndrome who was treated with high-dose(5mg/kg QOD) levamisole. This 15 year-old girl with steroid dependent nephrotic syndrome, who was negative for HLA B27, was treated with the usual recommended dose of levamisole(2.5mg/kg QOD). She developed agranulocytosis after 5 weeks of therapy and completely recovered in 11 days after discontinuation of levamisole.

The novel antipsychotic, olanzapine, has structural and pharmacological properties similar to clozaine. Antipsychotic drugs, as well as mood stabilizers, can cause neutropenia, which can progress to life-threatening agranulocytosis if the medication is not discontinued. We report two cases of reversible neutropenia associated with a olanzapine-valproate combination treatment. This report suggests that patients treated with the combination of olanzapine and valproate should be monitored for the occurrence of leukopenia and neutropenia.

Aceclofenac is a non-steroidal anti-inflammatory drug (NSAIDs) for inflammatory diseases. In this report, we report a serious adverse event (AE) occurred during the phase I clinical trial for a new sustained-release (SR) formulation of aceclofenac. There was a serious adverse event (AE), agranulocytosis, induced by aceclofenac SR form. An open-labeled, repeated-doses, randomized, crossover study was conducted at Kyung Hee University Hospital and 26 Korean healthy male volunteers were enrolled. All subjects received both aceclofenac SR 200 mg once daily and aceclofenac IR 100 mg twice daily for 4 days with 11 days washout period. After 11 days washout period, one subject showed a serious decrease in the segment neutrophil (267/mm3) on a laboratory test prior to the reference drug administration in period 2. We first report a case of agranulocytosis, during a phase I clinical trial.
