Effect of Traditional Chinese Medicine on Treating Antibiotic-Associated Diarrhea in Children: A Systematic Review and Meta-Analysis

Background

Due to the limited treatment options in antibiotic-associated diarrhea (AAD) in children, more effective treatments should be explored. Traditional Chinese medicine (TCM) has a long history in China, which has produced a pretty effect in clinical practice. Many randomized clinical trials (RCTs) have explored the effect of traditional Chinese medicine on treating AAD in children. However, there has been no systematic review or meta-analysis on the impact of TCM on AAD in children. The aim of this study was to systematically review RCTs on the effect of TCM in children with AAD.

Methods

RCTs in the past ten years on TCM for AAD in children were included. We searched Electronic databases as much as possible. This paper was registered in PROSPERO (CRD42022301034).

Results

26 studies were included in this systematic review. 25 studies reported the effects of TCM interventions on the total effective rate (RR = 1.20, CI 1.16 to 1.24; p < 0.001). 7 studies reported the effects of TCM interventions on the time to change the shape of feces (MD = −1.37, CI −1.67 to −1.07; p < 0.001). 17 studies reported the effects of TCM interventions (MD = −1.43, CI −1.71 to −1.15; p < 0.001). The pooled results showed that there were no significant differences between the two groups in CD3+, CD4+, CD8+, CD4 : CD8, time for bowel sounds to return to normal, hs-CRP, and IgM. There was a significant difference between the two groups in frequency of diarrhea on the third day after TCM intervention, vomiting improvement time, diamine oxidase, IL-8, TNF, IgA, IgG, and average hospital stay.

Conclusions

TCM interventions combined with conventional therapy can improve the therapeutic effect of AAD in children. However, future studies are still needed for the low methodological quality.

Tourette Syndrome Treatment Updates: a Review and Discussion of the Current and Upcoming Literature

Purpose of Review

This study aims to examine the treatments currently available for Tourette syndrome (TS) and to discuss evolving therapies, spanning behavioral, pharmacologic, complementary and alternative medicine, and neuromodulation approaches.

Recent Findings

Behavioral therapies have undergone several modifications to improve accessibility, including transitioning to a virtual format which is particularly important in the current pandemic. There are several recent or ongoing pharmacologic studies that have shown promise including the selective D1 receptor antagonist ecopipam and various cannabinoid compounds. Adaptive DBS may enable the physiologic markers of tics to determine stimulation parameters and improve tic outcomes related to neuromodulation.

Summary

In recent years, there has been a wealth of research across multiple treatment domains in the TS field. This review highlights exciting and new potential options for the future treatment of patients with TS.
