Objectives: To determine the best possible programme that suits our local setting, to determine the average dose required, and to determine possible problems that can arise from implementing such a programme locally and how best to address them. Methods: The inclusion criteria were those above 18, a positive urine test, the presence of a supportive carer and willing to engage in the programme. Methadone was initiated and observations relating to dose, adverse events, relationship with carers, work performance, crime and high risk behaviours were monitored for 18 weeks. Results: Two thirds of the 45 subjects completed the trial over the 18 week period. No significant adverse events occurred and improvement in relationship with carers and work performance were noted with reduction in crime and high risk behaviours. Conclusion: Methadone is a safe and effective drug that can be used in the local Malaysian setting.

INTRODUCTIONThis study aimed to determine the prevalence of metabolic syndrome and risk of coronary heart disease (CHD) in patients with schizophrenia receiving antipsychotics in Malaysia.

METHODSThis cross-sectional study, conducted at multiple centres, involved 270 patients who fulfilled the Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV-TR diagnostic criteria for schizophrenia, were on antipsychotic medications for at least one year, and were screened for metabolic syndrome. Patients receiving mood stabilisers were excluded. Metabolic syndrome was defined according to the National Cholesterol Education Program ATP III criteria modified for Asian waist circumference. Risk for cardiovascular disease was assessed by using Framingham function (all ten-year CHD events).

RESULTSThe prevalence of metabolic syndrome was 46.7% (126/270). Among all the antipsychotics used, atypical antipsychotics (monotherapy) were most commonly used in both the metabolic and non-metabolic syndrome groups (50.8% vs. 58.3%). The ten-year risk for CHD was significantly higher in patients with metabolic syndrome. The proportion of patients with high/very high risk for CHD (Framingham ≥ 10%) was greater in patients with metabolic syndrome than in those with non-metabolic syndrome (31.5% vs. 11.0%, odds ratio 3.9, 95% confidence interval 2.0-7.6; p < 0.001). The mean body mass index was higher in patients with metabolic syndrome than in those without (29.4 ± 5.1 kg/m2 vs. 25.0 ± 5.6 kg/m2; p < 0.001).

CONCLUSIONPatients with schizophrenia receiving antipsychotics in Malaysia have a very high incidence of metabolic syndrome and increased cardiovascular risk. Urgent interventions are needed to combat these problems in patients.
