Multikingdom and functional gut microbiota markers for autism spectrum disorder. Nat Microbiol 2024:10.1038/s41564-024-01739-1. [PMID: 38977906 DOI: 10.1038/s41564-024-01739-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Accepted: 05/20/2024] [Indexed: 07/10/2024]
Abstract
Associations between the gut microbiome and autism spectrum disorder (ASD) have been investigated although most studies have focused on the bacterial component of the microbiome. Whether gut archaea, fungi and viruses, or function of the gut microbiome, is altered in ASD is unclear. Here we performed metagenomic sequencing on faecal samples from 1,627 children (aged 1-13 years, 24.4% female) with or without ASD, with extensive phenotype data. Integrated analyses revealed that 14 archaea, 51 bacteria, 7 fungi, 18 viruses, 27 microbial genes and 12 metabolic pathways were altered in children with ASD. Machine learning using single-kingdom panels showed area under the curve (AUC) of 0.68 to 0.87 in differentiating children with ASD from those that are neurotypical. A panel of 31 multikingdom and functional markers showed a superior diagnostic accuracy with an AUC of 0.91, with comparable performance for males and females. Accuracy of the model was predominantly driven by the biosynthesis pathways of ubiquinol-7 or thiamine diphosphate, which were less abundant in children with ASD. Collectively, our findings highlight the potential application of multikingdom and functional gut microbiota markers as non-invasive diagnostic tools in ASD.

Abstract
Although Western medicine and ideas about atopic dermatitis (AD) have become popular in many Asian countries, local beliefs about the disease and its treatment often prevail. The multi- racial background of these countries as well as the influence of the diverse religions (such as Taoism and Ramadan) in these regions often lead to diverse belief systems about the causes of AD (such as the Chi concept, also known as the balance of yin and yang) and the types of treatment (e.g. herbal remedies, topical versus concoctions, and decoctions). In addition, many of the cultural practices are preserved among the Southeast Asian minorities residing in the United Kingdom and North America. Eastern treatments typically take a holistic approach to AD and emphasize the psychosomatic component of the disorder. This overview provides a summary of the difference between conventional, complementary, alternative, and integrative medicine in terms of epidemiology, aetiology, therapy, and prognosis in children with AD. There are a number of similarities in genetic and environmental factors in epidemiology and aetiology; however, differences exist in terms of the concept of management. Complementary and alternative medicine, traditional Chinese medicine, and integrative medicine usage are not only prevalent among the Asian population but are also becoming more popular and accepted in Western societies.

Exp Dermatol 2021; 30:859-864.

Abstract
Childhood eczema is common but its prevalence is variable in different regions of the world. In this study, we explore the associations of various risk factors such as the microbiome, environment, lifestyle, diet and maternal stress with the development of eczema among infants in Hong Kong. Upon enrolment in the study, the infants' parents provided demographic data by self-reporting. At enrolment and 1 year after birth, the infants' allergic conditions, lifestyles and dietary factors and the degree of maternal stress were assessed using various questionnaires. The infants' gut microbiomes were analysed by 16S RNA sequencing, and the longitudinal changes in various bacterial strains were compared between control and eczema-affected groups. Multivariate analyses (after adjustment for other significant factors) revealed that the changes in the abundance of Hungatella hathewayi in the gut were significantly associated with the development of eczema (p = 0.005). In conclusion, the increased abundance of Hungatella hathewayi was associated with an increased risk of developing eczema by 1 year of age. This study thus explored the potential risk factors for the development of eczema in Hong Kong infants, and sheds light on the possible association between early-life gut microbiome and other environmental factors.
