METHODS: This was an open-label, prospective, observational study involving 339 patients from Indonesia, Pakistan, Malaysia, Thailand, and Singapore. Brief Psychiatric Rating Scale (BPRS), Clinical Global Impression Severity scale (CGI-S), and safety parameters were assessed.
RESULTS: 62% of patients responded to olanzapine treatment, defined a priori as a reduction in BPRS of > 40% from baseline. Following the 8-week treatment period, the BPRS total, BPRS positive, BPRS negative, and CGI-S scores decreased by 18.7 (95% CI: 17.4, 20.2), 6.1 (5.6, 6.6), 2.9 (2.6, 3.2), and 1.5 points (median 1.0), respectively (p < 0.0001). In total, 31 of the 339 patients (9.1%) failed to complete the study according to the study description. Loss to follow-up and personal conflict were the most common reasons for discontinuation. There were 30 treatment-emergent adverse events with six serious cases, assessed as unrelated to study drug, reported.
CONCLUSION: This study further demonstrates the effectiveness and safety of olanzapine in actual clinical practice settings, in reducing the severity of psychopathological symptoms in Asian patients with schizophrenia.
DESIGN: This is a prospective, cohort study involving rural community residents.
SETTING: Rural community resident at Bingkor, Keningau, Sabah.
PARTICIPANTS: 363 individuals aged 13 years old and above.
INTERVENTION: Community-based participatory research to determine the prevalence and risk factors associated with alcohol use.
MAIN OUTCOME MEASURES: Measurement of alcohol use using Alcohol Use Disorders Identification Test (AUDIT) and assessment of psychiatric morbidity using Mini International Neuropsychiatric Interview (MINI) questionnaires.
RESULTS: Most alcohol drinkers aged between 36-45 years old, followed by 26-35 years old and 46-55 years old. Interestingly, there are almost similar female to male ratio. Most were Kadazan-Dusun ethnic, non-Muslims, and married. Although only less than a third of the participants received tertiary education, the majority were working. Based on the findings, being a male, non-Muslim and having an obsessive-compulsive disorder (OCD) (current) posed a significantly higher risk of alcohol consumption.
CONCLUSION: A worryingly high prevalence of hazardous alcohol consumption among the locals is reported. There is a need for population-wide intervention towards preventive measures based on the identified risk factors for hazardous alcohol use.
