ObjectiveAutism Spectrum Disorder is a neurodevelopmental disorder, with a rapid increase in recognition over the past decade. Interest in alternative therapies is growing annually, such as dietary therapies including gluten-free and/or casein-free diet, and the ketogenic diet. However, there is no consensus on the efficacy and safety of dietary therapy in children with ASD up to now. This study aimed to assess the efficacy and safety of these diet interventions for children with ASD based on a meta-analysis of global data.MethodsSeven databases (Cochrane Library, PubMed, EMBASE, Web of Science, VIP, CNKI, and Wanfang) were searched according to the established inclusion criteria, from the inception of the databases to August 18, 2021. The Cochrane Bias risk assessment tool was intended to assess the quality of the included studies. Review Manager 5.4 software was used as an efficacy analysis tool of the included studies, taking the core autistic symptoms and scales of ASD as therapeutic efficacy evaluations.ResultsIn total, 7 RCTs with 338 participants were finally obtained. All studies assessed the association between core autistic symptoms and therapeutic diet, showing a statistically significant effect (standard mean difference (SMD) of −0.51, 95% confidence interval (Cl): −0.81 to −0.21), in which two studies which followed the GFD diet reported significant reductions in social behaviors (SMD of−0.41, 95% Cl: −0.75 to −0.06), showing no correlation with the length of the interventions (P < 0.05). Two studies were performed in KD diet suggested a significant effect in core symptoms (SMD of −0.67, 95% Cl: −1.04 to −0.31). No statistically significant changes were observed in the GFCF diet, GFD diet, cognition, communication, and stereotypical behaviors subgroups (all P > 0.05).ConclusionThe results of a meta-analysis suggest that diet therapies can significantly ameliorate core symptoms of ASD, and GFD diets are conducive to improving social behaviors. Although the results suggest the effectiveness of dietary therapy for ASD, limited by the small sample size of RCTs, more well-designed, and high-quality clinical trials are needed to validate the above conclusions.Systematic Review Registrationhttps://www.crd.york.ac.uk/PROSPERO/, identifier: CRD42021277565.
Background Autoimmune encephalitis (AE) is a type of encephalopathy mediated by an antigenic immune response in the central nervous system. Most research related to autoimmune encephalitis (AE) is focused on early diagnosis, treatment and prognosis analysis; there has been little research conducted on the characteristics of immune function, and the relationship between immune function and prognoses of patients with autoimmune encephalitis needs to be studied further. Methods A total of 33 children with autoimmune encephalitis were identified through the clinic database and inpatient consults at Tianjin Children’s Hospital from January 2013 to January 2021. Based on the one-year follow-up and the modified Rankin Scale (mRS) prognosis score, they were divided into a good prognosis group and a poor prognosis group. The immune function characteristics of the two groups of children with autoimmune encephalitis (AE) were compared using Spearman correlation to analyse the mRS score and immune function indicators (IgA, IgG, IgM, CD4, CD8, CD4/CD8), and binary logistic regression was used to analyse the independent risk factors of the prognoses in patients with autoimmune encephalitis (AE). Results The differences in abnormal mental disorders and limb dyskinesia, cognitive impairment, onset types, modified Rankin Scale (mRS) scores at admission, and immune function status during remission between the two groups were statistically significant (p < 0.05). Conclusion There is a close correlation between modified Rankin Scale (mRS) scores and the immune function index CD4/CD8 in children with autoimmune encephalitis (AE) when they are admitted to the hospital. A young age, disturbance of consciousness, limb dyskinesia, abnormal immune function in remission and anti-NMDAR encephalitis are risk factors for poor prognoses in children with autoimmune encephalitis (AE). Clinical treatment requires more attention.
To the best of our knowledge, thus far there are no reported cases of melanotic neuroectodermal tumor of infancy (MNTI) with multiple complications. In this case report, we describe the clinical phenotype of MNTI in a 9-month-old female infant associated with tetralogy of Fallot (TOF), a congenital heart defect, and congenital hypothyroidism (CH). Our study showed that the growth of MNTI was delayed by a lower dosage of levothyroxine (L-T4) that was prescribed to treat CH because of the presence of TOF, a severe congenital heart disease. However, the standardized dosage of L-T4 improved thyroid function but stimulated the rapid growth of MNTI. Our report demonstrated that treatment with L-T4 affects the progression of MNTI. Our findings demonstrated the role of thyroid hormone in MNTI growth and progression. Furthermore, our study suggested that the treatment of co-morbidities in children with MNTI requires careful consideration of their effects on the growth and progression of MNTI.
