No Association between the rs1799836 Polymorphism of the Monoamine Oxidase B Gene and the Risk of Autism Spectrum Disorders in the Kazakhstani Population

A scoping review of autism research conducted in Central Asia: Knowledge gaps and research priorities

LAY ABSTRACT

Very little is known about the status of autism research in Central Asia. Through the library databases, we identified and reviewed 11 scientific studies conducted with autistic people and their families in five Central Asian countries-Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan. Of the 11 studies, 10 were conducted in Kazakhstan and 1 in Uzbekistan. Within these limited number of research studies, different topics such as diagnosis, risk factors of autism, biology, and various service and intervention areas were addressed. We identified several knowledge gaps and research priorities to address the needs of autistic people, their families, and professionals in Central Asia.

Stress, anxiety and depression in parents of children with autism spectrum disorders in Kazakhstan: prevalence and associated factors

INTRODUCTION

Studies worldwide reported increased levels of stress among parents of children with autism due to the unique caregiving challenges. While research has shown that parents' and autistic child's demographics and behavioral characteristics are associated with psychological distress among caregivers of children with autism, very few studies have investigated the impact of the caregiver's unmet needs on various aspects of the perceived family burden.

METHODS

This cross-sectional study examined the prevalence of stress, anxiety and depressive symptoms among a wide range of 146 parents with different sociodemographic characteristics, social support and unmet needs who care for children with autism spectrum disorder. These parents were recruited from autism non-governmental organizations and the National Children's Rehabilitation Center in Astana, Kazakhstan, a post-Soviet country in Central Asia. Multiple linear regression analyses were utilized to examine the relationship of parental psychological distress variables with social support, unmet needs and parental and child sociodemographic characteristics.

RESULTS

Significantly higher levels of stress and depression were reported among parents who perceived their needs as being unmet or extremely unmet as addressed by societal acceptance as compared to parents who reported adequate levels of needs met by social acceptance. Employed parents and parents with a higher level of perceived friends' support had less symptoms of stress, anxiety, and depression.

CONCLUSIONS

Increasing public awareness about autism and providing early detection and interventions for distressed caregivers of children with autism may be helpful in improving healthy functioning of parents and the entire family.

Autism and the Knowledge and Beliefs of Specialists in Kazakhstan

In Kazakhstan, the diagnosis of autism relies upon the expertise of various specialists and a range of measures that have not been researched to date. The present study collected data from a range of health specialists across Kazakhstan currently known to be involved in the diagnosis of children with autism. The research was an explanatory mixed methods design; survey followed by interviews. Participants included psychiatrists, pediatric neurologists, general practitioners, and other specialists. Analysis showed a range of beliefs including common misconceptions concerning the etiology and manifestation of autism not aligned with current research knowledge. These beliefs were shown to persist across disciplines and were not restricted to any specific region of the country, or particular profession.

Detention in Juvenile Correctional Facilities Is Associated with Higher Platelet Monoamine Oxidase B Activity in Males

Juvenile delinquency is related to several biological factors, yet very few vulnerability biomarkers have been identified. Previous data suggest that the enzyme monoamine oxidase B (MAO-B) influences several personality traits linked to the propensity to engage in delinquent behavior. Building on this evidence, we assessed whether conduct disorder (CD), juvenile delinquency adjudications, or detention in a correctional facility were associated with either platelet MAO-B activity or the MAOB rs1799836 polymorphism. The study enrolled 289 medication-free male youths, including 182 individuals detained in a correctional facility (with or without a diagnosis of CD). Of the remaining 107 participants, 26 subjects had a diagnosis of CD, and 81 were mentally healthy controls. Platelet MAO-B activity was determined by spectrophotofluorometry, while MAOB rs1799836 was genotyped using qPCR. Platelet MAO-B activity, corrected for age and smoking, was significantly higher in juvenile detainees (p < 0.001), irrespective of CD diagnosis. MAOB rs1799836 was not associated with platelet MAO-B activity or with detention in a correctional facility, CD diagnosis, or delinquent behavior. These data suggest that detention in a juvenile correctional facility increases platelet MAO-B activity in male adolescents. Future studies are needed to determine the mechanisms and functional significance of MAO-B peripheral elevation in juvenile male detainees.
