Leong Bin Abdullah MFI, Singh D, Swogger MT, Rahim AA, Vicknasingam B

Asian J Psychiatr, 2019 Jun;43:197-201.
PMID: 31302592 DOI: 10.1016/j.ajp.2019.07.008

BACKGROUND: Kratom is a traditional medicinal herb widely used in Malaysia and Thailand. Despite its widespread use and statements by regulatory agencies on the potential for kratom-associated psychosis, there is little data regarding the prevalence of psychotic symptoms among kratom users. This study investigated the prevalence of psychosis among kratom users, described psychotic symptomatology and severity, while examining associations between kratom use characteristics and the occurrence of psychotic symptoms.
METHODS: This cross-sectional clinical survey recruited 150 regular kratom users. The Mini International Neuropsychiatric Interview (MINI) and Diagnostic and Statistical Manual of Mental Disorders 5th Edition (DSM-V) diagnostic criteria were used to evaluate psychotic symptomatology among kratom users, and the Brief Psychiatric Rating Scale (BPRS) was used to assess the severity of psychiatric symptoms. Chi-square tests with Yate's correction were performed to determine the association between kratom use characteristics and the occurrence of psychotic symptoms among kratom users in this study.
RESULTS: Six out of 150 kratom users (4%) presented with any psychotic symptoms. The psychotic symptoms reported were positive symptoms and thought alienation, with a mean BPRS score of 33 (i.e., mild severity). Variables related to kratom use (such as intake of kratom with diphenhydramine, duration of kratom use, and quantity and frequency of daily kratom use) were not associated with the occurrence of psychotic symptoms among kratom users.
CONCLUSION: Although psychotic symptoms could occur among regular kratom users, they were rare and not significantly associated with kratom use characteristics. We found no evidence of elevated psychosis among regular users.

Sir, Delirium is defined as a clinical state characterised by an acute fluctuating change in mental status with inattention and altered levels of consciousness. Delirium in the older person is a common manifestation of sepsis,• electrolyte imbalance, intracranial pathology, urinary retention, fecal impaction, myocardial pathology or drug related. In this letter, we would like to share a report of an acute episode of delirium in a 94 year old man most likely induced by Clarithromycin which is a component of triple therapy for Helicobacter pylori (H. plyoriJ eradication.

The objective of this study was to determine the risk of lifetime and current methamphetamine-induced psychosis in patients with methamphetamine dependence. The association between psychiatric co-morbidity and methamphetamine-induced psychosis was also studied.

Antiepileptic-induced Psychosis as a Possible Predictor of Post-temporal Lobectomy Alternative Psychosis

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.

Association of a functional FAAH polymorphism with methamphetamine-induced symptoms and dependence in a Malaysian population

Sim MS, Hatim A, Reynolds GP, Mohamed Z

Pharmacogenomics, 2013 Apr;14(5):505-14.
PMID: 23556448 DOI: 10.2217/pgs.13.25

FAAH is a membrane enzyme that terminates the activity of a large class of endogenous signaling lipids. Recent studies suggest that the FAAH Pro129Thr polymorphism is a common mutation in the FAAH gene that is significantly associated with drug-addictive traits. This study investigated the association of the Pro129Thr polymorphism of the FAAH gene with methamphetamine dependence, methamphetamine-induced psychosis, manic episodes and panic disorder in a Malaysian population.

The past decade has seen a marked increase in the popularity of ATS use, particularly methamphetamine, within East Asia,and the Pacific region. In Malaysia, the National Anti Drug Agency has identified 8,870 addicts (from January till August 2008) out of which 1,126 was ATS dependence. During the same period, the police have arrested 46,388 people under the Dangerous Drug Act 1952. They also has seize 283kg of syabu, 545kg of ecstacy powder, 66194 tablets of esctacy pills and 222,376 tablets of yaba pills from Jan till August this year. The occurrence of psychosis arising from the use of ATS was first reported in the late 1930's. With growing ATS use, particularly methamphetamine, ATS-induced psychosis has become a major impact on public health.Symptoms of ATS-induced psychosis: Methamphetamine use produces a variety of effects, ranging from irritability, to physical aggression, hyperawareness, hypervigilance, and psychomotor agitation. Repeated or high-dose use of the stimulant can cause drug-induced psychosis resembling paranoid schizophrenia, characterized by hallucinations, delusions and thought disorders. When used in long term, methamphetamine may lead to development of psychiatric symptoms due to dopamine depletion in the striatum. The most common lifetime psychotic symptoms among methamphetamine psychotic patients - as reported in a cross-country study involving Australia, Japan, the Philippines and Thailand - are persecutory delusion, auditory hallucinations, strange or unusual beliefs and thought reading. Those patients were also reported to suffer from impaired speech, psychomotor retardation, depression and anxiety. An ATS psychosis can be distinguished from primary psychotic disorders by time. In ATS-induced psychosis symptoms usually resolve after the drug is discontinued. If symptoms do not resolve within 2 weeks after cessation of stimulant use, a primary psychiatric disorder should be suspected. When compared with other stimulants, such as cocaine, psychosis is induced more commonly by ATS, possibly due to the longer duration of action produced by amphetamines.For example, while smoking cocaine produces a high that lasts for 20-30 minutes, smoking methamphetamine produces a high that lasts 8-24 hours. Other symptoms of ATS-induced psychosis reported include affective blunting,(6) violent behavior, and self-mutilation and self-injurious behavior.
