RESUMO
AIMS: Misoprostol is a prostaglandin E1 analogue that is used to prevent nonsteroidal anti-inflammatory drug (NSAID)-induced gastrointestinal disorders. The aim of this systematic review and meta-analysis was to evaluate whether use of misoprostol also decreases the risk of NSAID-induced kidney injury. METHODS: Randomized controlled trials that compared misoprostol vs. placebo in an adult patient population were selected. The primary outcome was kidney injury and the secondary outcome was severe adverse events. The quality of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation approach. RESULTS: Twelve studies were eligible for inclusion. Although the rates of kidney injury and severe adverse events did not differ significantly between misoprostol and placebo, a posthoc subgroup analysis that excluded studies in which different NSAIDs were used in the misoprostol and placebo groups suggested that misoprostol may reduce the risk of NSAID-induced kidney injury (risk difference -0.09, 95% confidence interval -0.15 to -0.03, P < .01, I2 = 87%; evidence of very low certainty). CONCLUSION: There is limited evidence that misoprostol reduces the risk of NSAID-induced kidney injury. Misoprostol possibly contributes to reducing the risk of kidney injury associated with chronic NSAID use. The findings of this meta-analysis suggest further high-quality clinical trials are warranted.
RESUMO
OBJECTIVES: To evaluate the efficacy and safety of Yokukansan (TJ-54) in patients undergoing surgery. METHODS: Efficacy was assessed by the onset of delirium, delirium rating scales, anxiety evaluated by Hospital Anxiety and Depression Scale-Anxiety (HADS-A) score, and safety was assessed by any reported adverse events. RESULTS: Six studies were included. There were no significant differences between the groups in the onset of delirium (risk ratio 1.15, 95% confidence interval [CI] 0.77-1.72), delirium rating scales (early postoperative period: standardized mean difference [SMD] -0.24, 95% CI -1.11 to 0.63; late postoperative period: SMD -0.06, 95% CI -1.56 to 1.45), HADS-A score (mean difference -0.47, 95% CI -1.90 to 0.96), and any adverse events (risk ratio 1.18, 95% CI 0.35-4.00). CONCLUSIONS: The use of TJ-54 in patients undergoing surgery is not an effective strategy for postoperative delirium and anxiety. Further research considering target patients and durations of administration should be conducted.

Hangeshashinto has attracted attention owing to its potential to prevent chemotherapy-induced diarrhea. However, studies on the efficacy of Hangeshashinto have had conflicting results. Evaluating the efficacy of Hangeshashinto may contribute to reducing the use and adverse events caused by drug therapy for chemotherapy-induced diarrhea. Medical Literature Analysis and Retrieval System Online (MEDLINE), PubMed, Ichushi, the Cochrane Central Register of Controlled Trials (CENTRAL), and ClinicalTrials.gov were searched to retrieve all the relevant studies. Randomized controlled trials (RCTs) comparing the administration of Hangeshashinto with that of other treatments in patients with cancer receiving chemotherapy were included. The primary outcome was severe (grade 3-4) diarrhea assessed using the Common Terminology Criteria for Adverse Events. The secondary outcome was mild (grade 0-2) diarrhea. Out of 324 records identified, three studies were selected for the meta-analysis. Irinotecan was used for chemotherapy in all these studies. Hangeshashinto did not reduce the incidence of severe diarrhea compared with other treatments (risk ratio (RR) 0.40, 95% confidence interval (CI) 0.11-1.41, P = 0.15; low-quality evidence). Moreover, Hangeshashinto did not reduce the incidence of mild diarrhea (RR 1.35, 95% CI 0.87-2.09, P = 0.18; low-quality evidence). However, in the subgroup analysis compared with no treatment, the Hangeshashinto group had a significantly lower incidence of severe diarrhea (RR 0.17, 95% CI 0.03-0.88, P = 0.03; low-quality evidence). At present, insufficient evidence exists to support the claim that Hangeshashinto prevents diarrhea caused by irinotecan-based chemotherapy.
