    George S, Chin CN
    Med J Malaysia, 1998 Sep;53(3):223-6.
    PMID: 10968157
    This paper reports the characteristics and psychopathology of alcohol dependents with alcohol induced psychotic disorder admitted to the Seremban Hospital. The method is that of a case study of all alcohol dependents with alcohol induced psychotic disorder admitted to the Psychiatric Ward, Hospital Seremban over 3 years (1993-1995). There were 34 subjects, 30 Indians, 3 Chinese and 1 Malay with a mean age of 43 years. 32 were men and predominantly of Social Class IV and V (91%). They had a mean duration of drinking of 14.2 years and had a mean weekly consumption of 69.5 units of alcohol. There was a family history of alcohol dependence in (44%). The majority (68%) consumed samsu with beer the second choice. Auditory hallucinations (26) and delusions (16) were common while visual hallucinations (3) and depression (2) were less frequent. Speech disorder occurred in 4 subjects. 2 developed delirium tremens and 1 died. Liver function test was normal in 55%. All except the death from delirium tremens responded to treatment with a combination of anxiolytics, thiamine and antipsychotics and were rapidly discharged. The mean stay was 7 days. However, (68%) did not return for follow up and only 4 were abstinent from alcohol at the time of follow up.

    PMID: 10971979
    The aim of this study was to evaluate the efficacy and side effects of zuclopenthixol acetate compared with haloperidol in the management of the acutely disturbed schizophrenic patient. Suitable subjects diagnosed as having schizophreniform disorder or acute exacerbation of schizophrenia admitted to the psychiatric wards Hospital Kuala Lumpur were randomised to receive either zuclopenthixol acetate or haloperidol. They were rated blind for three consecutive days using the Brief Psychiatric Rating Scale (BPRS), Clinical Global Impression (CGI) and UKU Side Effects Scale. Apart from repeat injections of the same medication, no other anti-psychotic was given for the duration of the study. 50 subjects entered the study of which 44 completed. 23 were given zuclopenthixol acetate and 21 haloperidol. Both groups significantly reduced BPRS and CGI scores on all 3 days compared to the initial rating (p < 0.001). There was however no difference between the zuclopenthixol acetate and haloperidol group scores on all days (p > 0.05). More subjects on haloperidol than zuclopenthixol required more than 1 injection during the study. Both groups had minimal side effects. Zuclopenthixol acetate was effective in the management of the acutely disturbed schizophrenic.

    Schizophrenia is a chronic psychiatric disorder and pharmacotherapy plays a major role in its management. The 1950s and early 1960s saw milestones in the introduction of psychotropic drugs in clinical practice. A review of drug prescriptions in different settings provides an insight into the pattern of drug use, identifies drug-related problems and may be used to compare recommended guidelines with actual practice. This effort led to the evaluation of the drug prescribing pattern of antipsychotics in patients attending the psychiatric clinic at a government hospital. The data from 371 antipsychotic medication prescriptions that included 200 prescriptions for schizophrenia were collected during one month (1rst-31rst August 2008) at the outpatient pharmacy department. The mean age of patients was 35.0 years (SD = 1.131), with a male to female ratio of 2:1. The most widely used oral antipsychotic was haloperidol (16.3%) while the most common depot preparation prescribed was zuclopenthixol decanoate (8.8%). The daily dose of the average antipsychotic prescribed in this clinic was 342.06 mg equivalent of chlorpromazine. There was no relation between the doses received and ethnicity of the patient (Malay, Chinese or Indian). However, there was a significant relationship between the prescribed dose and patient age (P < 0.042). Nearly 32% of the schizophrenia patients were prescribed with atypical antipsychotics such as olanzapine (10.8%), risperidone (10.0%), quetiapine (7.6%) and clozapine (3.2%). Monotherapy was given to 73.0% of the schizophrenia patients. The majority of patients also received antidepressants. To conclude, this study gave evidence that physicians had a strong preference for monotherapy with conventional antipsychotic drugs while the use of atypical drugs was less prevalent.

  5. Adjunctive mood stabilizer treatment for hospitalized schizophrenia patients: Asia psychotropic prescription study (2001-2008)
    Sim K, Yong KH, Chan YH, Tor PC, Xiang YT, Wang CY, et al.
    Int. J. Neuropsychopharmacol., 2011 Oct;14(9):1157-64.
    PMID: 21557883 DOI: 10.1017/S1461145711000563
    Recent studies indicate relatively high international rates of adjunctive psychotropic medication, including mood stabilizers, for patients with schizophrenia. Since such treatments are little studied in Asia, we examined the frequency of mood-stabilizer use and its clinical correlates among hospitalized Asian patients diagnosed with schizophrenia in 2001-2008. We evaluated usage rates of mood stabilizers with antipsychotic drugs, and associated factors, for in-patients diagnosed with DSM-IV schizophrenia in 2001, 2004 and 2008 in nine Asian regions: China, Hong Kong, India, Korea, Japan, Malaysia, Taiwan, Thailand, and Singapore. Overall, mood stabilizers were given to 20.4% (n=1377/6761) of hospitalized schizophrenia patients, with increased usage over time. Mood-stabilizer use was significantly and independently associated in multivariate logistic modeling with: aggressive behaviour, disorganized speech, year sampled (2008 vs. earlier), multiple hospitalizations, less negative symptoms, younger age, with regional variation (Japan, Hong Kong, Singapore>Taiwan or China). Co-prescription of adjunctive mood stabilizers with antipsychotics for hospitalized Asian schizophrenia patients increased over the past decade, and was associated with specific clinical characteristics. This practice parallels findings in other countries and illustrates ongoing tension between evidence-based practice vs. individualized, empirical treatment of psychotic disorders.

  6. Antiepileptic-induced Psychosis as a Possible Predictor of Post-temporal Lobectomy Alternative Psychosis
    Benedict F, Lim KS, Jambunathan ST, Hashim AH
    East Asian Arch Psychiatry, 2016 Sep;26(3):109-11.
    PMID: 27703099
    We present a patient with topiramate-induced psychosis who developed alternative psychosis following temporal lobectomy. The number of surgical candidates for temporal lobectomy is increasing as is the frequency of psychiatric co-morbidities. Preoperative planning should take account of these psychiatric co-morbidities. In particular, precautions should be taken when antiepileptic drug-induced psychosis occurs, as this could predict the occurrence of alternative psychosis following lobectomy.

  7. Antipsychotic Polypharmacy in Older Adult Asian Patients With Schizophrenia: Research on Asian Psychotropic Prescription Pattern
    Dong M, Zeng LN, Zhang Q, Yang SY, Chen LY, Sim K, et al.
    J Geriatr Psychiatry Neurol, 2019 11;32(6):304-311.
    PMID: 31480982 DOI: 10.1177/0891988719862636
    BACKGROUND AND OBJECTIVE: Antipsychotic polypharmacy (APP) is a controversial topic in the treatment of older adults with schizophrenia. The objective of this study was to examine the use of APP in older adult Asian patients with schizophrenia and its associated demographic and clinical factors.

    METHODS: This study was based on the fourth survey of the consortium known as the Research on Asian Psychotropic Prescription Pattern for Antipsychotics. Fifteen Asian countries/territories participated in this survey, including Bangladesh, Mainland China, Hong Kong, India, Indonesia, Japan, Korea, Malaysia, Myanmar, Pakistan, Singapore, Sri Lanka, Taiwan, Thailand, and Vietnam. Basic demographic and clinical characteristics were collected using a standardized data collection form.

    RESULTS: Among the 879 older adults with schizophrenia included in the survey, the rate of APP was 40.5%. Multiple logistic regression analysis revealed that higher antipsychotic doses (P < .001, odds ratio [OR] = 1.003, 95% confidence interval [CI]: 1.002-1.003), longer duration of illness (P = .02, OR = 1.845, 95% CI: 1.087-3.132), and the prescription of anticholinergics (P < .001, OR = 1.871, 95% CI: 1.329-2.635), second-generation antipsychotics (P = .001, OR = 2.264, 95% CI: 1.453-3.529), and first-generation antipsychotics (P < .001, OR = 3.344, 95% CI: 2.307-4.847) were significantly associated with APP.

    CONCLUSION: Antipsychotic polypharmacy was common in older adult Asian patients with schizophrenia. Compared to the results of previous surveys, the use of APP showed a declining trend over time. Considering the general poor health status of older patients with schizophrenia and their increased risk of drug-induced adverse events, the use of APP in this population needs careful consideration.

    Brexpiprazole (OPC-34712) is a novel serotonin-dopamine activity modulator, which has recently been approved by the U.S Food and Drug Administration for the treatment of schizophrenia. The aim of this paper is to systematically synthesize all data of the efficacy, safety and tolerability of Brexpiprazole in treating schizophrenia. The terms 'Brexpiprazole', 'OPC-34712' and 'schizophrenia' were searched. A total of 12 clinical trials with 7 available data records were found. The pooled effect size of Brexpiprazole 1 mg, 2 mg and 4 mg were all superior to placebo in terms of the change from baseline in positive and negative syndrome scale (PANSS) total score at week 6 (weighted mean difference = -3.74, p = 0.044; weighted mean difference = -5.76, p

    Tsoh JM, Leung HC, Ungvari GS, Lee DT
    Singapore Med J, 2000 Jul;41(7):359-62.
    PMID: 11026805
    The psychiatric morbidity following hysterectomy has received increasing attention. One of the sequelae of hysterectomy has been a brief, acute psychosis with excellent outcome, the etiology and pathomechanism of which is still unclear. Two Chinese patients born of Southeast Asian origin who manifested brief, acute psychosis following hysterectomy are presented. Therapy comprised drug treatment with low dose antipsychotics and benzodiazepines coupled with hypnosis and marital therapy to explore and treat the underlying pathology. Both psychotic states resolved. Follow-up at 12 months revealed stable mental condition in one subject; however, the second patient was lost to follow up. The impact of the womb's removal is explored in the context of the ethnicity of the patients and their sociocultural background.

    Ain MK, Rosdinom R, Raynuha M
    Int Psychogeriatr, 2015 Sep;27(9):1573-5.
    PMID: 25794136 DOI: 10.1017/S1041610215000332
    We report a Malay man, with underlying chronic medical illnesses, presenting with positive symptoms of schizophrenia, including Capgras syndrome (CS) at the age of 73. Physical examination and blood investigations were normal and brain CT scan showed age-related cerebral atrophy. Neuropsychological assessment showed probable right hemisphere lesions but relatively intact memory and intellectual functions. Several neuroleptics including depot injections were tried but ineffective. Positive symptoms including CS eventually improved with clozapine before his death from myocardial infarction. This case report highlights the uncommon occurrence of CS in treatment resistant schizophrenia (TRS) of very late onset and its treatment challenges.

    PMID: 8099240
    Nineteen acutely disturbed psychotic Asian patients were treated with a single intramuscular injection of 50 mg of zuclopenthixol acetate in Viscoleo. Patients were assessed clinically before and after treatment using the Brief Psychiatric Rating Scale (BPRS). Serum zuclopenthixol and the inactive geometric isomer trans(E)-clopenthixol were determined by high-performance liquid chromatography after intramuscular injection. All patients improved, with the BPRS being significantly reduced (p < 0.001) at 72 h after injection. Adverse effects were generally few. The mean +/- SEM serum zuclopenthixol concentrations at 24, 48, and 72 h were 19.9 +/- 2.8, 31.5 +/- 4.5, and 17.8 +/- 2.9 micrograms/L, respectively. trans(E)-Clopenthixol concentrations ranged from negligible to 39.5 micrograms/L. This study confirms that a single intramuscular injection of 50 mg is adequate for managing severely disturbed psychotic patients for the first 3 days. The serum zuclopenthixol concentrations attained in the Asian patients were higher than those reported in Caucasian psychiatric patients. In some patients, a considerable amount of zuclopenthixol had been transformed to trans(E)-clopenthixol.

    OBJECTIVE: To examine the prescription rates in cancer patients of three common psychotropic drugs: anxiolytic/ hypnotic, antidepressant and antipsychotic.

    MATERIALS AND METHODS: In this retrospective cohort study, data were extracted from the pharmacy database of University Malaya Medical Center (UMMC) responsible for dispensing records of patients stored in the pharmacy's Medication Management and Use System (Ascribe). We analyzed the use of psychotropics in patients from the oncology ward and cardiology from 2008 to 2012. Odds ratios (ORs) were adjusted for age, gender and ethnicity.

    RESULTS: A total of 3,345 oncology patients and 8,980 cardiology patients were included. Oncology patients were significantly more often prescribed psychotropic drugs (adjusted OR: anxiolytic/hypnotic=5.55 (CI: 4.64-6.63); antidepressants=6.08 (CI: 4.83-7.64) and antipsychotics=5.41 (CI: 4.17-7.02). Non-Malay female cancer patients were at significantly higher risk of anxiolytic/hypnotic use.

    CONCLUSIONS: Psychotropic drugs prescription is common in cancer patients. Anxiolytic/hypnotic prescription rates are significantly higher in non-Malay female patients in Malaysia.

  16. Fulltext Comparison of risperidone and other neuroleptics in the management of chronic schizophrenia using cognitive therapy
    Azhar MZ
    Med J Malaysia, 2000 Mar;55(1):7-13.
    PMID: 11072484
    A number of psychological approaches to alleviating psychotic symptoms have been reported in the literature. The latest technique among them is cognitive therapy (CT). This paper describes an open trial that makes use of cognitive psychotherapy to treat chronic drug resistant delusions (more than 2 years duration) in 20 patients with schizophrenia. The positive response of all patients with the absence of symptom replacement and maintenance of response at 3 months follow-up, seem to imply that this technique is useful and more effort needs to be invested into this new area of psychotherapy for psychosis. This paper also shows that those patients on risperidone maintenance respond better to CT than those on other neuroleptics.

  17. Concurrent antipsychotic use in older adults treated with antidepressants in Asia
    Dong M, Zeng LN, Zhang Q, Ungvari GS, Ng CH, Chiu HFK, et al.
    Psychogeriatrics, 2019 Jul;19(4):333-339.
    PMID: 30734411 DOI: 10.1111/psyg.12416
    AIM: Depressive disorders are common in old age. Antipsychotics (APs) are often used as an adjunctive treatment with antidepressants (ADs) in this population but its patterns of use in Asia are not known. This study explored the rate of combination of APs and ADs in older adult psychiatric patients in Asia.

    METHODS: This is a secondary analysis of the database of a multicentre study which recorded participants' basic demographical and clinical data in standardised format in 10 Asian countries and territories. The data were analysed using univariate and multivariate logistic regression analyses.

    RESULTS: A total of 955 older adult psychiatric in- and outpatients were included in this study. The proportion of concurrent AP and AD use was 32.0%, ranging from 23.3% in Korea to 44.0% in Taiwan. Multivariate logistic regression analysis found that younger age, inpatient status and diagnosis of schizophrenia, anxiety and other mental disorders were significantly related to a higher proportion of concurrent use of APs and ADs.

    CONCLUSION: Around a third of older adult psychiatric patients had concurrent AP and AD use in the Asian countries/regions surveyed. Considering the uncertain effectiveness and questionable safety of the AP and AD combination in this patient population, such should be cautiously used.

    Psychiatry Res, 2013 Dec 30;210(3):745-50.
    PMID: 24012164 DOI: 10.1016/j.psychres.2013.07.012
    Schizophrenia is one of the most expensive psychiatric illnesses. This study compared retrospectively health-care resources consumed 12 months before and 24 months after risperidone long-acting injection (RLAI) treatment in Hong Kong. A mirror-image analysis was conducted using data (N=191) from three public hospitals in Hong Kong from 2003 to 2007. The main outcome measure was hospitalisation cost. Other secondary outcomes such as hospitalisation episodes, outpatient visits and adverse events were also compared. A predictive model was established using linear regression based on generalised estimating equations. Analysis showed that RLAI was associated with a reduction in hospitalisation cost by HK$10,001,390 (24.7%) (HK$40,418,694 vs. HK$30,417,303; P-value <0.05). Days of hospitalisation were reduced by 1538 days (10.1%) (15,271 vs. 13,733; P-value <0.05). The predictive model estimated that the hospitalisation cost of patients using RLAI was only 11.1% (3.1-3.93%, 95% confidence interval (CI)) compared to those receiving conventional antipsychotics combined with oral risperidone. Cost of hospitalisation was significantly reduced after RLAI therapy. However, results should be considered as indicative or suggestive only, due to potential channelling bias where certain drug regimens are preferentially prescribed to patients with particular conditions. The findings from our study may be useful in health-care decision making considering treatment options for schizophrenia in resource-limited settings.

    A young male presented with many years of delusions and hallucinations, with concurrent heroin use and subsequent amphetamine uses. There were no depressive or manic symptoms and psychotic symptoms prior to the amphetamine use. After the trials of two atypical antipsychotics and later clozapine due to treatment resistance, adherence and functionality were poor and there was still persistent drug use. As a result, a long acting injectable adjunct was commenced, but only minimal effects were observed. However after initiation of directly observed treatment of clozapine with methadone, there has been functional and clinical response and drug use has ceased.
