Plain language summary
Irritable bowel syndrome (IBS) is considered both a health and a socioeconomic burden. Curative treatment for IBS is currently not available and current management strategies vary. Gut microbiota dysbiosis is increasingly considered as a vital factor in the etiopathogenetic of IBS; thus, gut microbiota are a potential therapeutic target. The aim of this study was to investigate the efficacy and safety of Bacillus clausii plus conventional treatment, compared with placebo plus conventional treatment, in children with IBS in Mexico. This study is a phase III, multicentre, randomised, placebo-controlled, double-blind, parallel clinical trial. Patients (n=259) were centrally randomised 1:1 to treatment with either B. clausii or placebo. Results show that IBS symptom relief in children was very high in both groups (B. clausii and placebo). In fact, there weren’t any significant differences between groups for proportion of patients with clinical improvements at Week 8 or any of the key secondary endpoints. Furthermore, the adverse event profile was similar between groups. Authors conclude that their study was not able to demonstrate the efficacy of B. clausii as an adjuvant to conventional treatment of patients with IBS.
Abstract
OBJECTIVES Current irritable bowel syndrome (IBS) treatments have limited efficacy and probiotics like Bacillus clausii (B. clausii) were found to be effective in the management of several gastrointestinal disorders. This phase III trial assessed the efficacy and safety of adding B. clausii (four strains: O/C, N/R, SIN, T), versus placebo, to conventional treatment of pediatric IBS in Mexico. METHODS Patients aged 6-17 years 11 months with IBS (Rome IV) for at least 2 months were randomized to receive either B. clausii (oral suspension, total dose 4 billion spores/day) or placebo once daily for 8 weeks. All patients also received conventional treatment. The primary endpoint was the difference in the proportion of patients with clinical improvements at Week 8 (Global Assessment Questions [GAQ]). Secondary endpoints included responders by Subject's Global Assessment of Relief for Children with IBS (SGARC); number/consistency of stools; abdominal distention/bloating; abdominal pain/intensity; and IBS behavior. RESULTS 73.6% (95% confidence interval [CI] 67.3-80.0; B. clausii n = 129) and 78.5% (95% CI 72.5-84.4; placebo n = 130) of patients had symptom improvement (p = 0.8182). For Week 8 SGARC, 19.2% (B. clausii) and 20.9% (placebo) reported complete symptom relief. Stool evaluations, bloating, abdominal pain/intensity, and IBS behavior were similar between groups. Both treatments were well tolerated. CONCLUSION No significant differences in efficacy between B. clausii and placebo were demonstrated in addition to conventional treatment. The sample size calculation was based on an expected placebo/conventional treatment response of 30-40%. However, the actual treatment response observed was 80% and, thus, a study with larger population would be warranted. In addition, this study was conducted during the COVID-19 pandemic, when such controlled social conditions may have resulted in better diet, greater family stability, less psychological stress, and lower risk of infections exacerbating IBS, thereby improving symptoms in both groups.

Plain language summary
Coronavirus disease-19 (Covid-19) usually lasts for 7-10 days but in a proportion of individuals, long-term symptoms may develop such as fatigue, which can last for at least 12 weeks. Disruptions to the immune system and parts of the cell which produce energy have been observed in these individuals. This randomised control trial of 200 individuals aimed to determine the combined effects of two different multi-enzyme and probiotic supplements; ImmunoSEB and ProbioSEB on Covid-19 induced fatigue. The results showed that supplementation resolved fatigue and lowered fatigue in those who were still fatigued after 14 days compared to taking a placebo. Mental fatigue was also reduced in the supplemented group compared to placebo. It was concluded that 14 days of supplementation with ImmunoSEB and ProbioSEB resolves post-Covid-19 fatigue. This study could be used by health care professionals to recommend the supplementation of ImmunoSEB and ProbioSEB to improve feelings of and in some case resolve fatigue associated with Covid-19.

Summary Review:
This study reports on a randomized, multicentric, double-blind, placebo-controlled trial that was conducted in n=200 subjects with post-COVID-19 fatigue and without active SARSCoV-2 infection, living in India. This study sought to assess the efficacy of a multi-enzyme formulation administered with a probiotic complex on COVID-19-induced fatigue.
Subjects were between the ages of 18 and 75 years, with RT-PCR, confirmed diagnosis of COVID-19 at any time followed by an RT-PCR negative test who experienced fatigue and muscle weakness. Subjects were randomized to a test arm (n = 100), an oral supplement of a systemic enzyme complex and a probiotic complex for 14 days, or the control arm (n = 100) which used a placebo.
The multi-enzyme supplement formulation included Peptizyme SP, an enteric coated serratiopeptidase, bromelain, amylase, lysozyme, peptidase, catalase, papain, glucoamylase and lactoferrin. The probiotic supplement included, a blend of Bacillus coagulans LBSC (DSM 17654), Bacillus subtilis PLSSC (ATCC SD 7280) and Bacillus clausii 088AE (MCC 0538).
Treatment efficacy was compared using the Chalder Fatigue scale (CFQ-11), at various time points from days 1 to 14. At endpoint, 200/200 subjects finished the study.
Primary clinical outcomes were:
- The supplemental treatment resulted in the resolution of fatigue by 182 of 200 (91%) in the test arm compared to 30 of 200 (15%) in the control arm on day 14 (p<0.001)
- A beneficial effect was seen even at earlier time points, with a greater proportion of patients in the test arm being fatigue- free on days 4 (16% vs. 0%), 8 (44% vs. 2%), and 11 (87% vs. 7%) vs. the control arm (p<0.001).
The supplements were well tolerated with no adverse events reported.
Secondary clinical outcomes were:
- Subjects in the test arm showed a significant reduction in total as well as physical and mental fatigue scores at all time points vs. the control arm (p<0.001)
- On day 14, there was a significant reduction in all individual measures of physical fatigue (tiredness, need to rest, drowsiness, ability to do things, energy level, muscle strength and feeling of weakness) as well as mental fatigue (concentration, focus and memory) in the test arm vs. the control arm (p<0.001).
Clinical practice applications:
- There have been reports of post-viral fatigue syndrome up to 12 months in other coronavirus infections such as severe acute respiratory syndrome (SARS) and the Middle East respiratory syndrome (MERS). A lengthy post-infection fatigue impairs quality of life and has a significant impact on individuals, employers, and the healthcare system. It is therefore essential for clinicians to have early interventions to promote recovery of COVID-19 patients.
- Based on this study, practitioners could therefore consider multi-enzymes and probiotics together with other evidence-based multidisciplinary care approaches to improve functional status and quality of life in patients suffering from post-viral fatigue from COVID-19.
Considerations for future research:
- The treatment period of the study was a one-time intervention of 14 days with no long-term follow-up. A long-term follow-up of patients in future studies is needed to evaluate the potential of recurring fatigue.
- Future studies are also needed to replicate these findings and to test for certain inflammatory and immunity markers to provide further insight into the mechanism of action of supplementing with multi-enzymes, Bacillus coagulans, Bacillus subtilis, and Bacillus clausii.
- Additionally, further investigation is needed to evaluate the effectiveness of multi-enzymes, Bacillus coagulans, Bacillus subtilis, and Bacillus clausii in patients with persistent fatigue for six months or beyond to address the needs of patients suffering from chronic fatigue.
- All the subjects in the study were of Indian ethnicity, therefore further studies of other ethnicities are required.
- This study was capped at 75-year-olds, thus studies in older subjects are warranted.
- Conflict of interest statement: This study was fully funded by the manufacturer of the specialty enzymes and probiotics and the authors are paid employees of the manufacturer.
Abstract
Muscle fatigue and cognitive disturbances persist in patients after recovery from acute COVID-19 disease. However, there are no specific treatments for post-COVID fatigue. Objective: To evaluate the efficacy and safety of the health supplements ImmunoSEB (systemic enzyme complex) and ProbioSEB CSC3 (probiotic complex) in patients suffering from COVID-19 induced fatigue. A randomized, multicentric, double blind, placebo-controlled trial was conducted in 200 patients with a complaint of post-COVID fatigue. The test arm (n = 100) received the oral supplements for 14 days and the control arm (n = 100) received a placebo. Treatment efficacy was compared using the Chalder Fatigue scale (CFQ-11), at various time points from days 1 to 14. The supplemental treatment resulted in resolution of fatigue in a greater percentage of subjects in the test vs. the control arm (91% vs. 15%) on day 14. Subjects in the test arm showed a significantly greater reduction in total as well as physical and mental fatigue scores at all time points vs. the control arm. The supplements were well tolerated with no adverse events reported. This study demonstrates that a 14 days supplementation of ImmunoSEB + ProbioSEB CSC3 resolves post-COVID-19 fatigue and can improve patients' functional status and quality of life.
