Background and Aims: There is a high prevalence of gastrointestinal-related (GI) symptoms among children with autism spectrum disorder (ASD), which is associated with the severity of behavioral symptoms. Fecal microbiota transplantation (FMT) is a proposed therapeutic strategy that aims to address the dysregulation of the gut microbiome among children with ASD. Our study performed the first systematic review aimed to evaluate the benefits of FMT on the behavioral and gastrointestinal symptoms of pediatric patients with autism. Methods: A literature search was performed using variations of the keywords “pediatrics” and “fecal microbiota transplantation” in PubMed, EMBASE, CINAHL, Cochrane, and Web of Science from inception to 30 June 2022. Four studies that met the eligibility criteria were included in the systematic review. The efficacy of FMT on behavioral symptoms was measured by the difference in Aberrant Behavior Checklist (ABC) and Child Autism Rating Scale (CARS) scores before and after FMT. Results: We found a statistically significant improvement (p < 0.05) in ABC and CARS scores following FMT, with a statistically significant decrease in scores observed across all studies. In addition, substantial improvements in gastrointestinal symptoms were observed across all studies. Conclusion: Our findings suggest that FMT may offer a promising intervention for treating both behavioral and gastrointestinal symptoms in pediatric patients with autism.

Purpose of Review: Hepatitis B virus reactivation (HBVr) can complicate the use of immunosuppressive, antiviral, and chemotherapeutic medications in individuals with a history of prior exposure to HBV or chronic infection. Timely management is crucial to prevent fatalities. This review focuses on the various classes of biologics linked to the risk of HBVr, with emphasis on newer immunosuppressive and immunomodulator therapies. Recent Findings: Immune checkpoint inhibitors, tyrosine kinase inhibitors, cytokine inhibitors, and chimeric antigen receptor T-cell immunotherapies are associated with a high risk of hepatitis B virus reactivation (HBVr) in patients who are hepatitis B surface antigen-positive (HbsAg-positive). This risk decreases significantly when patients start nucleoside analogue (NA) prophylaxis. It is recommended to use NA prophylaxis alongside these medications and closely monitor for reactivation upon discontinuation of NA prophylaxis. Summary: To minimize the risk of reactivation when starting immunosuppressive, antiviral, and chemotherapeutic agents in individuals at high, intermediate, and low risk for hepatitis B virus reactivation (HBVr), it is crucial to employ specific strategies for risk assessment, monitoring, and management.

The rate of alcoholic hepatitis (AH) has risen in recent years. AH can cause as much as 40–50% mortality in severe cases. Successful abstinence has been the only therapy associated with long-term survival in patients with AH. Thus, it is crucial to be able to identify at-risk individuals in order to implement preventative measures. From the patient database, adult patients (age 18 and above) with AH were identified using the ICD-10 classification from November 2017 to October 2019. Liver biopsies are not routinely performed at our institution. Therefore, patients were diagnosed with AH based on clinical parameters and were divided into “probable” and “possible” AH. Logistic regression analysis was performed to determine risk factors associated with AH. A sub-analysis was performed to determine variables associated with mortality in AH patients. Among the 192 patients with alcohol dependence, there were 100 patients with AH and 92 patients without AH. The mean age was 49.3 years in the AH cohort, compared to 54.5 years in the non-AH cohort. Binge drinking (OR 2.698; 95% CI 1.079, 6.745; p = 0.03), heavy drinking (OR 3.169; 95% CI 1.348, 7.452; p = 0.01), and the presence of cirrhosis (OR 3.392; 95% CI 1.306, 8.811; p = 0.01) were identified as characteristics more commonly found in the AH cohort. Further, a higher inpatient mortality was seen in those with a probable AH diagnosis (OR 6.79; 95% CI 1.38, 44.9; p = 0.03) and hypertension (OR 6.51; 95% CI 9.49, 35.7; p = 0.02). A higher incidence of mortality was also noted among the non-Caucasian race (OR 2.72; 95% CI 4.92; 22.3; p = 0.29). A higher mortality rate despite a lower incidence of alcohol use among non-Caucasian patients may indicate healthcare disparities.
