Increasing resistance towards antibiotics has augmented the use of probiotics for the treatment of diarrhea and associated symptoms. Probiotics are active microorganisms which exert some health benefits when consumed in the right amount. This randomized, double-blind, placebo-controlled clinical trial was conducted on 60 "intention to treat" subjects to evaluate the safety and efficacy of probiotic preparation Lactic Acid Bacillus (LAB containing active ingredient Bacillus coagulans strain LBSC) for the treatment of acute diarrhea with abdominal discomfort.
The Test-A arm (n = 30) was on B. coagulans LBSC [2 billion/g] and Placebo-B arm (n = 30) was on the carrier. The primary outcomes were the time to last unformed stool (TTLUS), number of unformed stools, change in severity of abdominal pain, time to complete resolution of abdominal discomfort, complete remission of diarrhea, and quality of life (QoL). The secondary outcomes were physical examination and vitals, hematological analysis, and assessment of reported adverse events (AEs) or serious adverse events (SAEs).
Trial data showed that the LAB was well-tolerated by participants at the dose provided. The LAB was effective in recovering from acute diarrhea with abdominal pain and discomforts and exhibited improved cluster of QoL. No AEs or SAEs were reported during the trial.
It is evident that the test drug, i.e., LAB (B. coagulans strain LBSC) is safe and effective for improving the pathophysiological conditions related to acute diarrhea and abdominal discomfort evaluated through stage-II clinical trial.
对抗生素耐药性的增加促使益生菌在治疗腹泻及相关症状中的使用增多。益生菌是活性微生物,适量摄入时会带来一些健康益处。本随机、双盲、安慰剂对照临床试验针对60名“意向性治疗”受试者开展,以评估益生菌制剂乳酸杆菌(含活性成分凝结芽孢杆菌菌株LBSC)治疗伴有腹部不适的急性腹泻的安全性和有效性。
试验A组(n = 30)服用凝结芽孢杆菌LBSC[20亿/g],安慰剂B组(n = 30)服用载体。主要结局指标为最后一次不成形大便的时间(TTLUS)、不成形大便次数、腹痛严重程度变化、腹部不适完全缓解时间、腹泻完全缓解情况以及生活质量(QoL)。次要结局指标为体格检查和生命体征、血液学分析以及对报告的不良事件(AE)或严重不良事件(SAE)的评估。
试验数据表明,参与者对所提供剂量的乳酸杆菌耐受性良好。乳酸杆菌对伴有腹痛和不适的急性腹泻恢复有效,并改善了生活质量指标。试验期间未报告不良事件或严重不良事件。
显然,通过II期临床试验评估,受试药物即乳酸杆菌(凝结芽孢杆菌菌株LBSC)在改善与急性腹泻和腹部不适相关的病理生理状况方面是安全有效的。
