Int J Psychiatry Med. 2024 Sep;59(5):536-544. doi: 10.1177/00912174231214647. Epub 2023 Nov 16.

Abstract

Background: This case explores the challenges encountered in managing treatment-resistant paranoid schizophrenia, focusing on the limitations of using clozapine due to the risk of neutropenia. The United Kingdom Clozapine Patient Monitoring Service (UK CPMS) and its eligibility criteria are discussed, highlighting the potential benefits of expanding access to clozapine for patients who could potentially benefit from this medication. The integration of clozapine genetic testing as a personalized approach is explored, emphasizing the importance of identifying patients with a favorable genetic profile for clozapine response.Methods: Case report.Results: The case presentation of Mr. X exemplifies the difficulties faced in managing treatment-resistant schizophrenia when access to clozapine is restricted, leading to persistent negative symptoms.Conclusion: The article underscores the importance of innovative solutions and personalized care to enhance the treatment outcomes for patients with treatment-resistant paranoid schizophrenia. It acknowledges that certain restrictions of clozapine use may limit the effective management of patients with this condition.

Keywords: UK clozapine patient monitoring service; clozapine; genetic testing; neutropenia; treatment-resistant paranoid schizophrenia.
