Neutropenia in Patients With Clozapine-Treated Schizophrenia: An Effect of Clozapine or a Consequence of SARS-CoV-2 Infection? A Systematic Review.

Am J Ther 2022 Jun 24. Epub 2022 Jun 24.

Universitatea Transilvania, Braşov, Romania; and.

Background: Clozapine is the only approved antipsychotic for treatment-resistant schizophrenia. Despite its therapeutic benefits, it is still widely underused, mainly because of its potential to cause agranulocytosis and neutropenia. Prescribing clozapine in COVID-19-positive patients became more challenging because of this potential side effect. Read More

[Neutropenic enterocolitis in the pediatric cancer patient].

Rev Chilena Infectol 2022 02;39(1):59-69

Hospital Clínico San Borja Arriarán, Chile.

Neutropenic enterocolitis (NEC) is a heterogeneous disease of the gastrointestinal tract with systemic response, that corresponds to a severe and life-threatening clinical condition in immunocompromised patients, especially in childhood cancer. The pathologic features are poorly understood, although its multifactorial cause of NEC is well established and it is associated with the cytotoxic effects of the chemotherapy agents used and recognized by the classic triad of fever, neutropenia, and abdominal pain, secondary to gastrointestinal injuries that alters mucosal permeability and helps intramural bacterial invasion. NEC is truly a clinical challenge that requires an early diagnosis and a multidisciplinary approach including basic laboratory and imagological tests in high complexity centers. Read More

Pharmacogenomics of Clozapine-induced agranulocytosis: a systematic review and meta-analysis.

Pharmacogenomics J 2022 Jun 16. Epub 2022 Jun 16.

Campbell Family Mental Health Research Institute, Centre for Addiction and Mental Health, Toronto, ON, Canada.

Although clozapine is the most effective pharmacotherapy for treatment-resistant schizophrenia, it is under-utilized, and initiation is often delayed. One reason is the occurrence of a potentially fatal adverse reaction, clozapine-induced agranulocytosis (CIA). Identifying genetic variations contributing to CIA would help predict patient risk of developing CIA and personalize treatment. Read More

Metagenomic shotgun sequencing of blood to identify bacteria and viruses in leukemic febrile neutropenia.

PLoS One 2022 16;17(6):e0269405. Epub 2022 Jun 16.

Division of Infectious Diseases, Mayo Clinic College of Medicine and Science, Rochester, Minnesota, United States of America.

Despite diagnostic advances in microbiology, the etiology of neutropenic fever remains elusive in most cases. In this study, we evaluated the utility of a metagenomic shotgun sequencing based assay for detection of bacteria and viruses in blood samples of patients with febrile neutropenia. We prospectively enrolled 20 acute leukemia patients and obtained blood from these patients at three time points: 1) anytime from onset of neutropenia until before development of neutropenic fever, 2) within 24 hours of onset of neutropenic fever, 3) 5-7 days after onset of neutropenic fever.

Unmasking of Metamizole-Induced Liver Injury by Simultaneous Development of Characteristic Agranulocytosis.

Curr Drug Saf 2022 Jun 6. Epub 2022 Jun 6.

Department of Medicine B, Gastroenterology, Hepatology, Endocrinology and Clinical Infectiology, University Hospital of Münster; Albert-Schweitzer-Campus 1, D-48149 Münster, Germany.

Background: Metamizole is one of the most used analgesic, antipyretic, and spasmolytic agents in many countries worldwide. While metamizole-induced agranulocytosis is an, albeit seldom, well-known adverse event, metamizole-associated drug-induced liver injury has been reported rarely in the literature and hence often remains unconsidered. Here, we present a unique case where metamizole-induced hepatotoxicity got unmasked by the simultaneous development of characteristic agranulocytosis. Read More

Case Report: First Report of T-Cell Large Granular Lymphocytic Leukemia With NPL-DHX9 Gene Fusion Successfully Treated With Cladribine: Clinical Experience and Literature Review.

Front Oncol 2022 6;12:824393. Epub 2022 May 6.

Department of Pharmacy, Xiangya Hospital, Central South University, Changsha, China.

Background: T-cell large granular lymphocytic leukemia (T-LGLL) is a rare lymphoproliferative disorder that starts in T cells and is usually indolent. Long-term use of immunosuppressants, combined with agranulocytosis, is a double-edged sword, as both can lead to serious infections, especially in patients with combined hematologic malignancies and immune defects.

Case Presentation: A 30-year-old female patient was admitted to the hospital because of agranulocytosis for five years, with chest tightness, fatigue, and fever for two days. Read More
