Neutropenia is an adverse effect of various pharmacological therapies, including antipsychotics. However, risperidone tends to have a lower risk hematotoxicity. We report case 14 years old boy with diagnosis autism who developed neutropenia after administration and was able resolved it discontinuation. This rare risperidone-induced on adolescent.

Severe congenital neutropenia includes a variety of hematological disorders characterized by severe neutropenia with absolute neutrophil counts (ANCs) below 500/ml and associated with severe systemic bacterial infections from early infancy. The genetic basis of many of the inherited forms of congenital neutropenia have been documented. Genetic alterations have also been identified in multifacet...

X-linked neutropenia (XLN) is a rare form of Congenital Neutropenia (CN) caused by inherited gain-of-function mutations of WAS. Here we report 2 cases of the original L270P X-linked neutropenia kindred that evolved to MDS or AML, with acquisition of G-CSFR (CSF3R) mutations and monosomy 7. Thus, leukemic transformation with acquisition of CSF3R mutations and monosomy 7 is not restricted to clas...

Neutropenia is a common reason for hematology consultations in the inpatient and outpatient settings and is defined as an absolute neutrophil count less than 1500 cells/μL. Neutropenia varies in severity, with more profound neutropenia being associated with higher rates of infections and infection-related deaths. The causes for neutropenia are diverse and include congenital and acquired conditi...

background:  infections  in  neutropenic  patients  are  considered  as  major  causes  of  mortality and the emergence of drug resistance. gram positive bacterial infections are crucially important to be covered if indicated. vancomycin is active against most gram positive bacteria including methicillin resistant staphylococcus aureus (mrsa). in this study, we evaluated the appropriate utiliza...

Our understanding of the pathogenesis of congenital and acquired neutropenia is rapidly evolving. New ground-breaking observations have identified the genes responsible for many of the congenital neutropenia syndromes and are also providing new insights into normal neutrophil commitment and differentiation. Acquired neutropenia remains a poorly understood syndrome, although new insights into it...
