PURPOSE/BACKGROUND: Clozapine is associated with hematological abnormalities, with neutropenia and agranulocytosis of most concern. Granulocyte colony-stimulating factor (G-CSF) has been used to support clozapine rechallenge after neutropenia with the aim of maintaining the neutrophil count. This study aims to explore the practice, use, safety, and efficacy of G-CSF in this context. METHODS/PROCEDURES: We conducted a systematic review to identify all studies investigating or describing G-CSF as a prophylaxis to enable continued clozapine treatment during a rechallenge...

Cocaine use is increasing around the world and its purity is frequently altered through dilution, substitution, contamination, and adulteration. Sugars, talc, starch, and carbonates represent the principal diluents of cocaine, while phenacetin, levamisole, caffeine, and lidocaine are its major adulterants in Europe. Levamisole is used because it is an odorless powder, with physical properties similar to cocaine, and it has reasonable cost and availability, being widely used in veterinary medicine. For this study, we analyzed 88 cocaine samples...

Patients with hepatocellular carcinoma (HCC) exhibit a high incidence of concomitant cirrhosis with leukopenia and/or thrombocytopenia. In the present study, perioperative changes in the white blood cell (WBC) and platelet (PLT) counts and associated complications were investigated to assess the safety of transcatheter arterial chemoembolization (TACE) for HCC patients with preprocedural leukopenia or thrombocytopenia. The records of 1,461 HCC patients who received TACE between January 2012 and December 2013 were retrospectively reviewed...

Although anti-neutrophil antibodies (ANAs) often exist and immunoreaction may be involved in agranulocytosis, few reports have so far described ANA-positive cases of agranulocytosis with an unknown etiology. We herein describe the case of a 69-year-old woman who presented with ANA-positive agranulocytosis. In this case, both the withdrawal of the drugs that had possibly caused neutropenia and the use of granulocyte-colony stimulating factor (G-CSF) were ineffective treatment measures. Approximately 2 weeks after the discontinuation of the suspected drugs, we initiated corticosteroid pulse therapy; the neutrophil count recovered by day 19 of steroid therapy...

INTRODUCTION: The analgesic metamizole (dipyrone) is not recommended during pregnancy due to limited experience. In several countries, metamizole has no market authorization because of agranulocytosis as a rare but severe adverse effect. However, in others, metamizole is available and widely used as a pain reliever, and its use occurs also during pregnancy, often followed by fears of potential teratogenic risk. METHODS: This prospective observational cohort study compared pregnancy outcomes of 446 women exposed with metamizole in the first trimester with a randomly selected control cohort comprising 887 women not exposed to metamizole...

Cocaine is often "cut" with various additives to increase the profitability of the drug. One of the most common additives on today's market is levamisole, an anthelmintic medication used to destroy and expel parasitic worms in animals. The use of levamisole-contaminated cocaine can result in agranulocytosis and vasculitis (inflammation and constriction of small blood vessels). The resulting clotting and decrease in peripheral blood flow lead to cutaneous lesions, particularly on the ears, face, hands, and feet, and in severe cases can cause generalized tissue necrosis throughout the entire body...

Agranulocytosis is a serious, although rare, adverse reaction to sulfasalazine, which is used to treat inflammatory joint and bowel disease. We performed a genome-wide association study comprising 9,380,034 polymorphisms and 180 HLA alleles in 36 cases of sulfasalazine-induced agranulocytosis and 5,170 population controls. Sulfasalazine-induced agranulocytosis was significantly associated with the HLA region on chromosome 6. The top hit (rs9266634) was located close to HLA-B, odds ratio (OR) 5.36 (95%CI [2...

BACKGROUND: Concerns exist that clozapine is underutilized in the management of treatment-resistant schizophrenia. Although a 2015 change in the US Food and Drug Administration (FDA) monitoring recommendations lowered the threshold of the absolute neutrophil count for treatment interruption from 1,500/μL to 1,000/μL and removed white blood cell count thresholds from the monitoring algorithm, the implications of this policy change on clozapine interruptions remain unknown. METHODS: We analyzed outpatient prescribing records for antipsychotic medications in the Veterans Integrated Service Network 7 (VISN 7) database between 1999 and 2012 to assess the potential impact of the recent changes in FDA neutropenia monitoring recommendations on clozapine treatment discontinuation...

Streptococcus pneumoniae is a main causative agent of serious invasive bacterial infections. However, concurrent infection with invasive pneumococcal disease (IPD) and viral infectious mononucleosis (IM) is rare. We report an infant with serotype 6C infection causing IPD occurring simultaneously with IM. A previously healthy 11-month-old girl referred to our hospital because of fever, leukopenia, and elevated C-reactive protein presented to us with disturbance of consciousness, tachycardia, tachypnea and agranulocytosis...

Thionamides, such as methimazole and propylthiouracil, are used for the management of hyperthyroidism. Agranulocytosis is a rare adverse effect of thionamides and elderly patients are especially vulnerable. Here we discuss a case of an 80-year-old woman who developed agranulocytosis and pneumonia approximately 4 weeks after starting low dose methimazole therapy. Despite aggressive treatment with broad-spectrum antibiotics and granulocyte colony stimulating factor, she developed multiorgan failure and died. Our goals are to identify risk factors common to elderly patients and hopefully improve outcomes in this population when prescribed thionamides...

The HLA-B*40:238 allele has one non-synonymous transversion from HLA-B*40:01:01 at nucleotide position 484. The HLA-B*40:238 allele was found in an association study between HLA and antithyroid drug-induced agranulocytosis (1) . The allele, initially genotyped in a Graves' disease patient showed one mismatched nucleotide within the combined sequence pattern of B*40:01:01 and B*13:01:01 using SeCore HLA Sequence-based typing kit (Life Technologies Corporation, WI, USA). To determine which allele the mismatch belonged to, polymerase chain reaction (PCR) was carried out to amplify exon 2 to exon 4 of the HLA-B region with dimorphic forward primers as described by Cereb et al (2) ...

INTRODUCTION: Drug reaction with eosinophilia and systemic symptoms (DRESS) is a severe toxidermia that can lead to death from multivisceral failure. We report a case of DRESS associated with febrile agranulocytosis in a child. OBSERVATION: An 8-year-old child was hospitalized for diffuse maculopapular exanthema with edema of the extremities and face associated with cheilitis and febrile agranulocytosis. This symptomatology began 1month after the introduction of carbamazepine for partial epilepsy...

Blood dyscrasias excluding agranulocytosis received limited attention in antipsychotic-treated patients during the first 18 weeks of therapy, although severe clinical conditions have been reported in a few cases. We extracted data records of 285 Caucasian patients after 18 weeks of antipsychotic treatments to investigate risk factors of blood dyscrasias. We observed a higher risk to develop both transient and persistent anemia, neutrophilia and eosinophilia in clozapine-treated patients, whereas in those treated with other atypical antipsychotics when compared to a reference group under typical antipsychotics, emerged an increased risk for transient neutrophilia and eosinophilia...

BACKGROUND Levamisole is a common adulterant of cocaine. It can cause agranulocytosis and cutaneous vasculitis that can possibly lead to cutaneous necrosis. In all reported cases of levamisole-induced vasculitis, it has been described as a clinical syndrome characterized by a constellation of typical clinical features and a positive serum serology for ANCA levels, especially very high-titer p-ANCA levels, in the background of cocaine abuse. However, patients may have a negative serology and here, we present the first such case...

BACKGROUND: There is a paucity of literature regarding the effect of antipsychotics on absolute neutrophil count (ANC) of patients with benign neutropenia (BN). We evaluated the change in ANC after atypical antipsychotic prescription (excluding clozapine) in a retrospective cohort of 22 patients with BN. METHODS/PROCEDURES: Records of all patients with BN who were prescribed antipsychotics and who had ANC measured before and during antipsychotic treatment were obtained from Bronx VA Medical Center between 2005 and 2015 (inclusive)...

Agranulocytosis is a rare condition with a reported incidence ranging from one to five cases per million population per year. Most commonly, agranulocytosis is secondary to chemotherapeutic agents, however, other medications have also been associated with it. An immune mediated destruction of circulating granulocytes and/or granulocyte precursors secondary to drug-dependent or drug-induced antibodies is the postulated mechanism. Agranulocytosis has also been reported secondary to recreational drug use...
