Plain language summary
Clostridium butyricum (CB) is a probiotic with potential for treating Irritable Bowel Syndrome (IBS). This randomised controlled trial aimed to assess the efficacy and safety of CB in treating diarrhoea-predominant IBS (IBS-D) and analyse the faecal microbiota after treatment. The study was carried out in China. 200 patients with IBS-D were recruited and were given CB or a placebo for four weeks. Researchers looked at changes in IBS symptoms, quality of life, stool consistency and frequency. CB was effective in improving the overall IBS-D symptoms as well as quality of life and stool frequency, but not abdominal pain or bloating. The responder rates (percentage of participants that experienced a reduction of 50 or more points in the IBS symptom severity scale) were higher in CB compared with the placebo, especially for those with moderate to severe IBS symptoms. The faecal microbiota analysis showed changes in the microbial community after treating with CB, including a reduction in the genus Clostridium.
Abstract
Irritable bowel syndrome (IBS) is a common disorder in gastrointestinal system and impairs the quality of life of the patients. Clostridium butyricum (CB) is a probiotics that has been used in several gastrointestinal diseases. The efficacy of CB in treating IBS is still unknown. This prospective, multi-centre, randomized, double-blind, placebo-controlled trial aimed to assess the efficacy and safety of CB in treating diarrhea-predominant IBS (IBS-D) and analyze the fecal microbiota after treatment. Two hundred patients with IBS-D were recruited and were given CB or placebo for 4 weeks. End points included change from baseline in IBS symptoms, quality of life, stool consistency and frequency. Compared with placebo, CB is effective in improving the overall IBS-D symptoms (-62.12 ± 74.00 vs. -40.74 ± 63.67, P = 0.038) as well as quality of life (7.232 ± 14.06 vs. 3.159 ± 11.73, P = 0.032) and stool frequency (-1.602 ± 1.416 vs. -1.086 ± 1.644, P = 0.035). The responder rates are found higher in CB compared with the placebo (44.76% vs. 30.53%, P = 0.042). The change in fecal microbiota was analyzed and function pathways of CB in treating IBS-D were predicted. In conclusion, CB improves overall symptoms, quality of life and stool frequency in IBS-D patients and is considered to be used as a probiotics in treating IBS-D clinically.

Abstract
INTRODUCTION Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used for the treatment of acute gouty arthritis but have the risk of gastrointestinal bleeding and cardiovascular toxicity. Glucocorticoid was as effective as oral NSAIDs in the initial treatment of gout arthritis of patients intolerant of NSAIDs. However, whether glucocorticoid has the same or preferable effect as oral NSAIDs on patients with acute gouty arthritis irrespective of gastrointestinal and cardiovascular risks factor remains unknown. This study was to compare the efficacy, safety and tolerance of compound betamethasone (diprospan) 7 mg intramuscular injection (i.m.) once for all during the study with diclofenac sodium 75 mg twice a day in the treatment of acute gouty arthritis. METHODS Sixty patients with acute gouty arthritis were randomised (1 : 1) to receive compound betamethasone 7 mg i.m. once for all during the study or diclofenac sodium 75 mg twice a day for 7 days in this open-label study. Pain intensity, tenderness, swelling and global assessment of response to therapy were collected as end-points for the treatment. RESULTS The mean change in pain intensity from baseline to Day 3 and Day 7 in both treatment groups demonstrated that compound betamethasone had preferable efficacy over diclofenac sodium on Day 3 and comparable efficacy on Day 7. The compound betamethasone group had fewer adverse effects (AEs) than diclofenac sodium group. No statistically significant differences were observed about serum uric acid levels at different pain intensity at baseline. CONCLUSIONS A single dose of compound betamethasone may be better than diclofenac sodium for the treatment of acute gouty arthritis.
