Abstract Background Clozapine possesses unique efficacy profile in treatment-resistant schizophrenia but is associated with neutropenia and agranulocytosis, in respectively, 3% and 0.7% of exposed patients. Granulocyte colony-stimulating factor (G-CSF) has been used to allow clozapine continuation or rechallenge in such situation (1,2). Methods We aim to describe the use of G-CSF to maintain clozapine despite neutropenia or agranulocytosis in treatment resistant schizophrenia patients in Quebec province, Canada. A national clozapine hematological monitoring database was consulted to identify all patients who have had red event (neutrophil count < 1,5 threshold) since 2004 in Quebec and was cross-referenced with hospital pharmacy software to identify patients who have received at least one dose of G-CSF while been exposed to clozapine All patients with an active cancer diagnosis while taking clozapine and G-CSF were excluded. A group of pharmacists specialized in psychiatry in Quebec was also contacted to ensure selecting all cases in the province. In additional to demographic data and clozapine and G-CSF details, Clinical Global Impression severity scale (CGI-S) was used to evaluate psychopathology severity during four critical turning points: before and after clozapine introduction, after agranulocytosis episode and after clozapine rechallenge. All data were collected retrospectively, using patient’s medical files, from January to July 2019. Results Eight (8) patients (5 males, 3 females), Caucasian, mean age 48 years old, with clozapine median exposition of 4.8 years, were identified. In 7/8 of those, G-CSF was used according to an “as required strategy”, i.e., whenever the patient’s neutrophil count dropped below a pre-determined threshold, varying according to patient between 0,8 à 1,5. In the other patient, a 3-weekly doses were preventively administered. Despite this, a mean number of 4 red events (ranging from 1 to 10 events) were subsequently observed in those patients, leading to clozapine cessation in 4/8 patients. One other patient responded to G-CSF but the clinical team felt uncomfortable to maintain clozapine in such circumstances. No complication (infection for instance) due to low neutrophil counts was observed nor any significant side effect related to G-CSF. However, in all these cases, while clozapine treatment was associated with clinically significant improvement of psychopathology (mean CGI-S decreased from 5.5 to 3.4), clozapine cessation led to an important psychotic deterioration (mean CGI-S of 6.2) at follow up. Fortunately, in patients successfully rechallenged (3/8), a strong clinical improvement was observed, with return to previous response level observed. Discussion To our knowledge, this is the largest case series of clozapine rechallenge using G-CSF and adds to the 39 already described cases in which G-CSF was concomitantly used with clozapine (1,2). While an “as required” strategy was mainly used here, a different prophylactic G-CSF use may have led to higher rates of clozapine maintenance, despite red codes, which provides the impetus for further studies.

AbstractClozapine is an atypical antipsychotic approved by the Food and Drug Administration for treatment-resistant schizophrenia and also indicated for the reduction in risk of recurrent suicidal behavior in patients with schizophrenia or schizoaffective disorder. The most serious side effect of clozapine treatment is agranulocytosis, which is defined as an absolute neutrophil count (ANC) < 0.50 × 109 per L. Benign ethnic neutropenia (BEN) is a condition found in members of African or Middle Eastern descent that is characterized by ANC < 1.50 × 109 per L in the absence of other causes. Filgrastim is a granulocyte colony-stimulating factor (G-CSF) that has shown efficacy in reducing the duration of agranulocytosis in some patients who develop clozapine-induced agranulocytosis. It is currently unknown whether filgrastim is beneficial in the treatment of neutropenia due to BEN. We here, for first the time report a case of a patient with BEN who developed agranulocytosis both during the first clozapine trial for schizophrenia and during the rechallenge, despite early stabilization with filgrastim treatment, which highlights the failure of filgrastim in treating BEN.Funding AcknowledgementsNo funding.

A patient in a medium secure psychiatric unit with a 19-year history of treatment-resistant schizophrenia and violence whose mental illness only responded to clozapine, was noted to have a sustained tachycardia. Echocardiography revealed mild biventricular cardiomyopathy. The patient was not significantly affected by this. Initial recommendation from Cardiology was to consider discontinuation of clozapine. It was decided, however, that the risk of worsening psychosis and resultant violence outweighed the risk of the patient’s relatively mild cardiomyopathy. The patient was commenced on ramipril, and later bisoprolol. The patient no longer requires treatment in a medium secure unit and has remained on clozapine with follow-up from cardiology.

Mental illness is a serious problem in the United States. Based on “current epidemiological estimates, at least one in five people has a diagnosable mental disorder during the course of a year.” Fortunately, many of these disorders respond positively to psychotropic medications. While psychiatrists write some of the prescriptions for psychotropic medications, primary care physicians write more of them. State legislatures, seeking to expand patient access to pharmacological treatment, granted physician assistants and nurse practitioners prescriptive authority for psychotropic medications. Over the past decade other groups have gained some form of prescriptive authority. Currently, psychologists comprise the primary group seeking prescriptive authority for psychotropic medications.The American Society for the Advancement of Pharmacotherapy (“ASAP”), a division of the American Psychological Association (“APA”), spearheads the drive for psychologists to gain prescriptive authority. The American Psychological Association offers five main reasons why legislatures should grant psychologists this privilege: 1) psychologists’ education and clinical training better qualify them to diagnose and treat mental illness in comparison with primary care physicians; 2) the Department of Defense Psychopharmacology Demonstration Project (“PDP”) demonstrated non-physician psychologists can prescribe psychotropic medications safely; 3) the recommended post-doctoral training requirements adequately prepare psychologists to prescribe safely psychotropic medications; 4) this privilege will increase availability of mental healthcare services, especially in rural areas; and 5) this privilege will result in an overall reduction in medical expenses, because patients will visit only one healthcare provider instead of two–one for psychotherapy and one for medication.

In the summer of 1979, a group of experts on law, medicine, and ethics assembled in Siracusa, Sicily, under the auspices of the International Commission of Jurists and the International Institute of Higher Studies in Criminal Science, to draft guidelines on the rights of persons with mental illness. Sitting across the table from me was a quiet, proud man of distinctive intelligence, William J. Curran, Frances Glessner Lee Professor of Legal Medicine at Harvard University. Professor Curran was one of the principal drafters of those guidelines. Many years later in 1991, after several subsequent re-drafts by United Nations (U.N.) Rapporteur Erica-Irene Daes, the text was adopted by the U.N. General Assembly as the Principles for the Protection of Persons with Mental Illness and for the Improvement of Mental Health Care. This was the kind of remarkable achievement in the field of law and medicine that Professor Curran repeated throughout his distinguished career.

Abstract The author, who is the editor of the Mental and Behavioral Disorders chapter of the AMA Guides to the Evaluation of Permanent Impairment (AMA Guides), Sixth Edition, comments on the previous article, Assessing Mental and Behavioral Disorder Impairment: Overview of Sixth Edition Approaches in this issue of The Guides Newsletter. The new Mental and Behavioral Disorders (M&BD) chapter, like others in the AMA Guides, is a consensus opinion of many authors and thus reflects diverse points of view. Psychiatrists and psychologists continue to struggle with diagnostic taxonomies within the Diagnostic and Statistical Manual of Mental Disorders, but anxiety, depression, and psychosis are three unequivocal areas of mental illness for which the sixth edition of the AMA Guides provides M&BD impairment rating. Two particular challenges faced the authors of the chapter: how could M&BD disorders be rated (and yet avoid an onslaught of attorney requests for an M&BD rating in conjunction with every physical impairment), and what should be the maximal impairment rating for a mental illness. The sixth edition uses three scales—the Psychiatric Impairment Rating Scale, the Global Assessment of Function, and the Brief Psychiatric Rating Scale—after careful review of a wide variety of indices. The AMA Guides remains a work in progress, but the authors of the M&BD chapter have taken an important step toward providing a reasonable method for estimating impairment.
