Association between maternal genitourinary infections and the risk of attention deficit hyperactivity disorder and autism spectrum disorder in children according to a systematic review

Abstract

Introduction. Autism spectrum disorders and attention deficit hyperactivity disorder are among the most significant and widespread mental disorders that manifest in childhood and adolescence. Their etiology and pathogenesis have not been studied enough and most likely a complex of factors leads to their formation. Among other things, data are accumulating on the role of various hazards and diseases of the mother, which increase the risk of neuropsychiatric disorders in offspring. These include genitourinary infections, whose contribution to the development of autism spectrum disorders and attention deficit hyperactivity disorder has not yet been systematically studied.Aim. To establish the contribution of maternal genitourinary infections to the formation of autism spectrum disorders and attention deficit hyperactivity disorder in children.Materials and methods. An electronic search was conducted in the Scopus and Pubmed databases to obtain relevant literature by August 2022. The search strategy included a combination of keywords and MESH terms: urogenital infections, and autism, and autism spectrum disorders, and attention deficit hyperactivity disorder, and maternal infections.Results. On this topic 10 papers have been identified in the available literature – 6 on autism spectrum disorders and 4 on attention deficit hyperactivity disorder. In all the papers on attention deficit hyperactivity disorder included in the analysis, an association between genitourinary infections and neuropsychiatric disorders was revealed. In the case of autism spectrum disorders, the data obtained were more contradictory. The heterogeneity of the available data (different designs, different deficits and approaches to the diagnosis of genitourinary infections) did not allow for a meta-analysis.Conclusions. Genitourinary infections play a pathogenetic role in the formation of attention deficit hyperactivity disorder, while the effect of genitourinary infections on the development of autism spectrum disorders seems less unambiguous. It is necessary to continue work in this area with a more unified design to form practical recommendations for the prevention of neuropsychiatric disorders.
