Stevens-Johnson syndrome is one of the few dermatological emergencies in clinical practice. The syndrome is often secondary to the usage of drugs, of which allopurinol, penicillins, sulfa drugs, ibuprofen, sodium valproate, phenytoin, lamotrigine and carbamazepine are commonly implicated. Agranulocytosis is the existence of a clinically significant reduction in neutrophil count. This condition is a serious threat to the patient, as he/she is at a greater risk of contracting bacterial or fungal infections, which may prove to be fatal...

OBJECTIVE: To investigate the infections occurring in the induction period of childhood acute lymphoblastic leukemia (ALL), the pathogens of the infections, and drug resistance of isolated strains. METHODS: A retrospective analysis was performed for the clinical data of 130 children with newly-diagnosed childhood ALL. Infections occurring during the induction chemotherapy, pathogenic strains, and drug-resistance spectrum were analyzed. RESULTS: The incidence rate of clinical infection and/or microbial infection reached 76...

BACKGROUND: Clozapine is the antipsychotic of choice for treatment-resistant schizophrenia; however, rigorous monitoring is required to prevent or detect adverse drug events that contribute to morbidity and mortality. In addition to the Food and Drug Administration (FDA) boxed safety warnings specific to clozapine (agranulocytosis, hypotension, seizures, and cardiomyopathy/myocarditis), other adverse events such as pneumonia and gastrointestinal hypomotility have been reported in the literature to result in hospitalization...

To evaluate efficacy and tolerability of the combination of clozapine with an antipsychotic long-acting injectable (LAI) in multi-episode patients with schizophrenia or schizoaffective disorder. Efficacy and tolerability were assessed in seventeen patients admitted to a hospital in Paris between January 2010 and June 2015, using a one-year mirror-image design. Number and length of hospitalizations significantly decreased after introducing the combination (2.1 vs 0.8, p=0.004 and 155.4days vs 26.6days, p<0...

BACKGROUND: Cocaine is a risk factor for acute kidney injury and chronic kidney disease with progression to end-stage renal disease. Levamisole is an adulterant that is added to cocaine to enhance its euphoric effects. Levamisole-adulterated cocaine (LAC) is associated with the distinct clinical syndromes of agranulocytosis, leukocytoclastic vasculitis, cocaine-induced midline destructive lesions (CIMDL), and ANCA-associated vasculitis (AAV) with pauci-immune necrotizing glomerulonephritis...

BACKGROUND: Parkinson's disease (PD) psychosis is encountered in as many as 50% of patients with advanced disease. Treatment options for PD psychosis are few. In fact, only clozapine and pimavanserin have shown efficacy in randomised controlled trials. Clinicians are often reluctant to prescribe the former, due to the risk of agranulocytosis, while the latter is not widely available yet. Because it is already clinically available and exhibits high affinity for serotonin 2A receptors, a target with which both clozapine and pimavanserin interact, we hypothesised that the anti-depressant mirtazapine might be effective to alleviate PD psychosis...

Agranulocytosis is a rare but serious complication of antithyroid drug therapy, and an up-to-date understanding of this topic is important. Both direct toxicity and immune-mediated responses have been described as possible mechanisms. Some major susceptibility loci have recently been identified, which may lead the diagnosis of agranulocytosis into a genomic era. Onset is acute and patients present with symptoms and signs of infection together with high fever. Clinical suspicion is pivotal and should prompt blood sampling...

OBJECTIVE: Finding agranulocytosis (AG) at an early stage is important to improve outcome, but periodic granulocyte count monitoring is not generally recommended for patients with Graves' disease, because AG develops suddenly. METHOD: At the Kuma Hospital, Graves' patients under antithyroid drug (ATD) treatment in an outpatient clinic have a granulocyte count examination during each visit, and if it is <1,000/μl, a warning is immediately sent to the patient's physician...

INTRODUCTION: Febuxostat, a nonpurine xanthine oxidase inhibitor, is approved as the first-line urate-lowering therapy in gout patients with normal renal function or mild to moderate renal impairment. The most common adverse effects of febuxostat are liver function test abnormalities, diarrhea, and skin rash. However, there is insufficient data in patients with severe renal impairment and end-stage renal disease (ESRD). We report the first case, to our knowledge, in which agranulocytosis developed after febuxostat treatment in an ESRD patient...

BACKGROUD: Few data is currently available on neutropenia and agranulocytosis related to drug intake. We report here data on 203 patients with established idiosyncratic drug-induced agranulocytosis, followed up in a referral centre within a university hospital. PATIENTS AND METHODS: Data from 203 patients with idiosyncratic drug-induced agranulocytosis were retrospectively reviewed. All cases were extracted from a cohort study on agranulocytosis in the Strasbourg University Hospital (Strasbourg, France) RESULTS: : The mean age was 61...

RATIONALE: Pregnancy is a complicated physiological process. Physiological leukocytosis often takes place and it is primarily related to the increased circulation of neutrophils, especially during the last trimester of pregnancy. Noncongenital agranulocytosis during pregnancy is rare and reported only occasionally, while in most of the cases, the agranulocytosis has already occurred prior to pregnancy or induced by identified factors such as antibiotics, antithyroid agents, or cytotoxic agents...

BACKGROUND: Data on the haematological outcomes of patients who continue clozapine treatment following neutropenia are very rare as even mild neutropenia results in mandatory discontinuation of clozapine in most countries. However, in Iceland where clozapine monitoring is less stringent allows an observational study to be done on the risk of agranulocytosis and neutropenia during treatment with clozapine compared with other antipsychotics among patients with schizophrenia. METHODS: The present study is a part of a wider ongoing longitudinal study of schizophrenia in Iceland...

Use of the atypical antipsychotic clozapine (CZP) is compromised by the risk of potentially fatal agranulocytosis/granulocytopenia (CIAG). To address this, we have established a simple, personalized cell culture-based strategy to identify CIAG-susceptible patients, hypothesizing that an immunogenic and possibly haptene-based mechanism underlies CIAG pathophysiology. To detect a putative haptene-induced response to CZP in vitro exposure, a traditional lymphocyte stimulation assay was adapted and applied to patient-specific peripheral blood-derived mononuclear cells (PBMC)...

BACKGROUND: Clozapine is the archetypical atypical antipsychotic, its primary indication being treatment resistant schizophrenia. Severe side effects caused by clozapine, including leukopenia, agranulocytosis, and myocarditis, are well known. A rarely described side effect is concurrent perimyocarditis and parenchymal lung disease. CASE PRESENTATION: A previously physically healthy 23-year-old male Caucasian that suffered from schizophrenia presented with flu-like symptoms 1 week after starting clozapine treatment...

OBJECTIVES: A prospective evaluation of nonchemotherapy drug-induced agranulocytosis (DIA) cases, which are infrequent in the pediatric population. We characterize agranulocytosis cases and assess lab test differences between drug- and nondrug-induced agranulocytosis. METHODS: Through our Prospective Pharmacovigilance Program from Laboratory Signals at Hospital we detected pediatric agranulocytosis cases from July 2007 to December 2010. This program estimates the incidence, drug causality, clinical features, outcomes of DIA pediatric cases, and assesses laboratory differences with respect to non-DIA...

Infectious mononucleosis secondary to Epstein-Barr virus typically follows a relatively benign and self-limited course. A small subset of individuals may develop further progression of disease including hematologic, neurologic, and cardiac abnormalities. A mild transient neutropenia occurring during the first weeks of acute infection is a common finding however in rare cases a more profound neutropenia and agranulocytosis may occur up to 6weeks following the onset of initial symptoms. We describe the case of an 18-year-old woman who presented 26days following an acute infectious mononucleosis diagnosis with agranulocytosis and fever...

Chronic Lymphocytic Leukaemia (CLL) is a monoclonal lymphoid malignancy characterized by progressive accumulation of small, mature but functionally incompetent neoplastic lymphocytes in the peripheral blood, bone marrow and lymphoid organs. Patients present a variable course and may not require early intervention unlike other malignancies. Patients with rapidly deteriorating blood counts, and organomegaly need treatment. Alkylating agent live Bendamustine combined with Rituximab, anti-CD 20 monoclonal antibody have shown promising results in such patients...

INTRODUCTION: Adolescence is a unique phase of the human developmental process. In adolescents, psychotropic medications may have different efficacy and tolerance profiles compared to those at other stages of the lifespan. Mood stabilizers are a complex pharmacological category including lithium, some anticonvulsants, and some second generation antipsychotics. Focusing on this class of pharmacological agents, we aim to answer the following questions: in which indications and according to which modalities should mood stabilizers be prescribed during adolescence? METHODS: Information was sought from the websites of the French Haute Autorité de santé (HAS) and Agence nationale de sécurité du médicament et des produits de santé (ANSM), the American Food and Drug Administration (FDA) and the British National Institute for Health and Clinical Excellence (NICE)...
