Abstract
Objective Clozapine is the first atypical antipsychotic drug and was frequently cited as the most effective antipsychotic for treatment-resistant schizophrenia, but it is associated with a concert of significant cardiotoxic side effects. Clozapine-induced Myocarditis (CIM) is diagnosed based on the combination of clinical symptoms, laboratory investigations, radiological findings, and sometimes biopsy. The literature on CIM management and clinical consensus on the best course of action is mixed. Methodology An all-language literature search on Medline, Cochrane, Embase, and Google Scholar until April 2022. The following search strings and Medical Subject Heading (MeSH) terms were used: "CIM," "clozapine," "cardiotoxicity," and "myocarditis." We explored the literature on CIM for its pathophysiology, diagnosis, monitoring, and management. Results The clinical features of CIM may be highly variable, ranging from asymptomatic disease to fulminant heart failure, and cessation of medication was the mainstay treatment of CIM, followed by supportive therapy. Other antipsychotics have also been linked with cardiotoxic side effects. Conclusion Despite being the most effective antipsychotic, clozapine is associated with a cardiotoxic side effect. Current literature suggests that these antipsychotic-related cardiotoxic events impact the treatment selection for schizophrenia and other psychotic disorders, and they must be kept in mind while designing new treatment protocols in the future.

Abstract
BACKGROUND The drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a drug-induced hypersensitivity reaction. AIMS Aim was to review reports of clozapine-related reactions fulfilling the registry of severe cutaneous adverse reaction (RegiSCAR) criteria for DRESS syndrome reported as such or otherwise, to provide a descriptive overview of demographic patterns, clinical manifestations, and DRESS course and investigate associations between demographic, DRESS parameters, and clinical outcomes. METHODS This review was conducted following preferred reporting items for systematic reviews and meta-analyses guidelines and registered with PROSPERO (registration number CRD42020156385). We searched PubMed/Embase/PsychInfo/Cochrane for reports of clozapine-related reactions meeting RegiSCAR criteria. Associations between RegiSCAR scores and time-to-recovery with demographic/clinical variables were assessed. Demographic/clinical characteristics of patients with versus without reported DRESS were compared using non-parametrical tests. RESULTS We identified 26 reports of 27 patients meeting RegiSCAR criteria. Males (n = 19, 70.4%) and patients with schizophrenia (n = 18, 66.7%) were mainly affected. Twelve patients (44.4%) received clozapine-monotherapy. DRESS symptoms manifested within a month after clozapine initiation (n = 24, 88.9%). Lungs and liver were the most common organs involved (n = 12, 44.4%; n = 11, 40.7%), with a mean time to recovery of 33.75 days. Clozapine rechallenge led to DRESS recurrence in four patients. Death rate was 7.4%. No associations were detected between RegiSCAR criteria or days to recovery with any demographic/clinical variables. No differences between patients with versus without reported DRESS were detected. CONCLUSIONS Clozapine-related DRESS may be rare, but also underreported. Clinicians need to be aware of it even in patients under clozapine-monotherapy or without skin rash.

The role of sulpiride in attenuating the cardiac, renal, and immune disruptions in rats receiving clozapine: mRNA expression pattern of the genes encoding Kim-1, TIMP-1, and CYP isoforms. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2020; 27:25404-25414.

Abstract
The present study was aimed to explore the cardio-, immuno-, and nephrotoxic effects of the antipsychotic agent clozapine (CLZ) and the alleviative potency of sulpiride (SPD) on these impairments in rats. For this purpose, 40 male rats were divided into four groups and were orally treated with saline (control), CLZ (0.5 mg/kg bw), SPD (28 mg/kg bw), or a combination of CLZ and SPD (CLZ+SPD), daily for 30 consecutive days. At necropsy, blood samples and specimens from the heart, kidneys, and spleen were collected for biochemical, molecular, and histopathological investigations. The results showed that CLZ administration was associated with significantly lower immune status indices and increased serum levels of pro-inflammatory cytokines, lactate dehydrogenase, malondialdehyde, cardiac, and renal tissues injury markers. Moreover, the mRNA expression levels of Kidney Injury Molecule-1 (Kim-1), tissue inhibitor of metalloproteinase-1 (TIMP-1), and cytochrome P450 (CYP) isoforms were markedly upregulated in CLZ-treated rats, compared to the control group. On the other hand, rats treated with SPD alone showed non-significant differences in terms of immune response indices, tissue injury markers, and mRNA expression levels of Kim-1, TIMP-1, and CYP isoforms. Finally, CLZ+SPD co-treatment significantly modulated almost all biochemical indices. Besides, Kim-1, TIMP-1, and CYP2C19 mRNA expression levels were significantly downregulated, while other CYP isoforms showed no modulation, compared with CLZ-treated group. Histopathologically, CLZ-treated rats showed severe lesions in renal, splenic, and cardiac tissues, compared with control rats, which were restored in CLZ+SPD-co-treated rats. Overall, these findings demonstrate that CLZ treatment induces significant cardiac, immune, and nephropathic alterations, which were reduced with CLZ+SPD co-treatment.

Abstract
OBJECTIVE To review the published literature on clozapine associated cardiotoxicity (CACT), summarize diagnostic features, and evaluate monitoring procedures for safe clozapine re-challenge. RESULTS Clozapine-associated Myocarditis (CAM) - Incidence of early myocarditis (≤2 months) is infrequent but serious. Clinical diagnosis is confounded by variability in presentation and non-specificity of symptoms. Re-challenge considerations include clozapine impact on symptomatic severity and associated disability and risk of suicidality. Re-challenging is recommended only after full clinical resolution of myocarditis and cardiac function impairment, under closely controlled conditions, starting at very low dosage, extremely slow titration and frequent assays of lab and cardio biomarkers. Clozapine associated cardiomyopathy (CAC) -develops later but mortality has been reported at 12.5-24.0%. Re-challenge is generally not recommended due to paucity of outcome data. Monitoring Cardiac Toxicity: Plausible steps include closer clinical monitoring, repeated assays of biomarkers, and echocardiographic studies, and cardiac MRI changes with unremarkable findings of cardiac dysfunction with echocardiography. Subclinical clozapine associated cardiotoxicity is more prevalent than CAM and CAC. Diagnosis is often challenging due to non specific presentation. Active monitoring is recommended. Rechallenging is feasible but should be done under close monitoring conditions. A protocol is proposed based on literature review and clinical experience in order to reduce the risk of CACT. CONCLUSION Clozapine-associated myocarditis and cardiomyopathy may have been underreported worldwide. Identification of subclinical cardiotoxic effects can improve outcomes by earlier recognition before clinical manifestations of cardiac impairments. A pragmatic close clinical monitoring protocol including cardiac biomarkers aimed at timely detection of cardiac toxicity, in the initial phase of treatment is proposed.

Abstract
Clozapine is exceptionally effective in psychotic disorders and can reduce suicidal risk. Nevertheless, its use is limited due to potentially life-threatening adverse effects, including myocarditis and cardiomyopathy. Given their clinical importance, we systematically reviewed research on adverse cardiac effects of clozapine, aiming to improve estimates of their incidence, summarize features supporting their diagnosis, and evaluate proposed monitoring procedures. Incidence of early (≤2 months) myocarditis ranges from <0.1 to 1.0 % and later (3-12 months) cardiomyopathy about 10 times less. Diagnosis rests on relatively nonspecific symptoms, ECG changes, elevated indices of myocardial damage, cardiac MRI findings, and importantly, echocardiographic evidence of developing ventricular failure. Treatment involves stopping clozapine and empirical applications of steroids, diuretics, beta-blockers, and antiangiotensin agents. Mortality averages approximately 25 %. Safety of clozapine reuse remains uncertain. Systematic studies are needed to improve knowledge of the epidemiology, avoidance, early identification, and treatment of these adverse effects, with effective and practicable monitoring protocols.
