Plain language summary
Endometriosis is a gynaecological condition with symptoms of pelvic pain, fatigue, and stress. Decreased quality of life, impaired fertility and hinderances to carry out day to day tasks are all associated with endometriosis. Treatment options involve medications and surgery; however, both are associated with poorer outcomes than the initial disease itself. Self-management strategies that the individual can perform themselves, such as lifestyle changes, meditation, and rest have all been used to improve the quality of life of individuals with endometriosis, however their effectiveness has not been determined. This systematic review and meta-analysis aimed to determine the effectiveness of self-management strategies for the management of endometriosis. The study showed that many self-management strategies were no more effective than placebo or hormonal therapies for the management of endometriosis. It was concluded that many self-management strategies were no more effective than hormonal treatment at reducing endometriosis symptoms and the studies that did show a benefit were insufficient to base recommendations on due to poor design. This study could be used by healthcare professionals to understand that currently the research on self-management strategies of endometriosis is poor and whilst some may be of benefit to individuals who cannot or do not want to take hormone therapy, more research is warranted.

Summary Review:
Introduction
Endometriosis is an inflammatory condition where endometrial-like tissue is found outside of the uterus. Diagnosis of endometriosis is made in around 6-10% of females of reproductive age. Endometriosis can adversely affect fertility, psychological well being and quality of life (QoL). Conventional interventions can have side effects and limited effectiveness. The aim of this systematic review (SR) was to evaluate the efficacy of self-management interventions for pain-related symptoms and QoL.
Methods
Fifteen experimental studies were included in this SR. Ten evaluated dietary supplements, three evaluated dietary modifications, one evaluated over-the-counter (OTC) medication, and one evaluated exercise. Outcome measures were self-reported for dysmenorrhoea, dyspareunia, overall pain, non-menstrual pelvic pain, use of medications and QoL.
Results
- Most dietary supplements were no more effective than placebo or frequently recommended medical interventions, at reducing pain-related outcomes.
- Melatonin (one RCT n=30) performed better than placebo for managing dysmenorrhoea and overall pain but not for non-menstrual pelvic pain. PEA-transploydatin (one RCT n=20) performed better than placebo for dysmenorrhoea and non-menstrual pelvic pain but not better than medical intervention.
- Resveratrol (one RCT n=22 & one intervention study n=12) plus the oral contraceptive pill (OCP) was more effective than the OCP alone for managing dysmenorrhoea.
- In one observational study, 75% of participants (n=295) reported a reduction in ‘high’ intensity pain scores following a 12-month gluten-free diet (p- value =<0.005). Similarly, a full dietary modification (one non randomised controlled trial , n=30) found less participants reporting pain at ‘high intensity’ (18%) compared to linseed and calcium oil supplements (41%) and placebo (62%).
- A metal trace element supplement was more effective than placebo for managing overall pain (one RCT p- value<0.001).
- Naproxen (one cross over trial, n=11) performed better than placebo at managing dysmenorrhoea (83% vs 41%, p- value 0.008).
- Hatha yoga (one RCT n=12) was found to be effective at reducing overall pain and improving QoL compared to no yoga (p-value <0.05).
Conclusion
Due to limited, low-quality evidence, high risk of bias and high levels of heterogeneity between studies, it was not possible to generalise the findings of the studies included in this systematic review. Further research of high-quality is needed in order to make self-management recommendations for females with endometriosis.
Notes: The authors reported no conflicts of interest.
Clinical practice applications:
Evidence-based self-management interventions are considered critical for the management of endometriosis. However, the quality of evidence in this SR was considered of poor quality. Further high-quality research is needed in order to be able to make recommendations. Strategies that showed potential benefits included:
- Dietary modifications and a gluten-free diet may be effective for reducing the intensity of pain associated with endometriosis.
- Hatha yoga may be effective at reducing overall pain and supporting psychological wellbeing and QoL.
Considerations for future research:
High quality studies are needed as well as a ‘gold standard’ definition for self-management criteria. Understanding potential barriers to self-management interventions may also be beneficial.
Abstract
Self-management is critical for the care of endometriosis. Females with endometriosis frequently use self-management strategies to manage associated symptoms; however, the efficacy of such strategies is unknown. The aim of this review was to systematically appraise the evidence concerning efficacy of self-management strategies for endometriosis symptoms. Electronic databases, including Medline, Embase, Emcare, Web of Science Core Collection, Scopus, and the Cochrane Central Register of Controlled Trials, were searched from inception to March 2021. We included peer-reviewed experimental studies published in English evaluating the efficacy of self-management strategies in human females laparoscopically diagnosed with endometriosis. Studies underwent screening, data extraction, and risk of bias appraisal (randomised studies: Risk of Bias 2 tool; non-randomised studies: Risk Of Bias In Non-randomized Studies - of Interventions tool). Of the fifteen studies included, 10 evaluated dietary supplements, three evaluated dietary modifications, one evaluated over-the-counter medication, and one evaluated exercise. Most studies had a high-critical risk of bias. Many self-management strategies were not more effective at reducing endometriosis symptoms compared to placebo or hormonal therapies. Where studies suggest efficacy for self-management strategies, no recommendations can be made due to the poor quality and heterogeneity of evidence. High-quality empirical evidence is required to investigate the efficacy of self-management strategies for females with endometriosis.

Plain language summary
Previous research has shown that the use of melatonin by individuals with irritable bowel syndrome (IBS) has improved symptoms and quality of life (QoL) but did not affect sleep. This research has been shown to have some limitations in that it has been conducted in a small number of individuals and did not use the latest IBS diagnostic criteria. This randomised control trial aimed to determine in 136 individuals with IBS with and without sleep disorders the effects of melatonin on IBS score, gastrointestinal (GI) symptoms, QoL, and sleep. The results showed that compared to placebo, the use of melatonin for 8 weeks resulted in improved IBS score and GI symptoms in individuals with and without sleep disorders. Severity and frequency of abdominal pain, satisfaction with bowel habits, disease impacts on life, and stool consistency were all improved, however frequency of defecations was unaffected. Sleep was improved in those with sleep disorders, but not those without. It was concluded that melatonin can be used to improve IBS and QoL in individuals with or without sleep disorders and may also improve sleep in those with sleep disorders and IBS. This study could be used by healthcare professionals to recommend the use of melatonin to individuals with IBS to improve symptoms and QoL.
Abstract
BACKGROUND Irritable bowel syndrome (IBS) is one of the world's most common gastrointestinal (GI) disorders, and current treatments do not meet patients' demands. This study aimed to investigate melatonin's therapeutic effects on IBS score, GI symptoms, quality of life, and sleep parameters in both groups of IBS patients with and without sleep disorders. METHODS In this randomized double-blinded placebo-controlled trial study, 136 patients with a diagnosis of IBS based on ROME IV criteria were enrolled and then divided into two groups respecting having sleep disorders or not. Patients of each group were randomized in a 1:1 ratio to receive melatonin 6 mg daily (3 mg fasting and 3 mg at bedtime) for 2 months (8 weeks). Blocked randomization was used in this process. All patients were evaluated both at the beginning and the end of the trial regarding IBS score, GI symptoms, quality of life, and sleep parameters through valid questionnaires. RESULTS In both groups of patients with and without sleep disorders, a significant improvement was observed in IBS score and GI symptoms, including the severity and the frequency of abdominal pain, the severity of abdominal bloating, satisfaction with bowel habits, disease's impact on patient's life, and stool consistency; however, there was no significant improvement in the frequency of defecations per week. In patients with sleep disorders, significant improvement in sleep parameters, including subjective sleep quality, sleep latency, sleep duration, sleep efficiency, and daytime dysfunction, was observed, while in patients without sleep disorders, there was no significant improvement in sleep parameters. In addition, quality-of-life improvement was observed in a significant number of melatonin recipients compared to placebo in both groups of patients. CONCLUSION Melatonin can be considered an effective treatment for improving IBS score, GI symptoms, and quality of life in IBS patients with and without sleep disorders. It is also effective to improve sleep parameters in IBS patients with sleep disorders. TRIAL REGISTRATION This study has been registered to the Iranian Registry of Clinical Trials (IRCT) with the approval number IRCT20220104053626N2 on the date of 13/02/2022.

Psoriasis is a common inflammatory skin disease that results in patches of dry, scaly skin that can be itchy or sore. Psoriatic arthritis is an inflammatory arthritis that affects up to 30% of psoriasis patients. There is growing interest in the association between the microbiome and inflammatory conditions. This systematic review examined the role of the oral and gut microbiota and the effect of probiotics in patients with psoriasis and/or psoriatic arthritis. 23 studies were included in the analysis. Studies examined the microbiota using culture or 16S ribosomal RNA gene sequencing analysis. The results showed an increased presence of Candida in the mouth, and an altered gut microbiota in patients with psoriatic disease compared with healthy controls. Probiotics were associated with a significant decrease in psoriasis severity, but the microbiota was unchanged. The study authors concluded that further research is required into the role of the microbiome in patients with psoriasis.
Abstract
Advances in technology have led to an increased number of studies investigating the microbiome in patients with psoriasis. This systematic review examined data regarding the oral and gut microbiota in patients with psoriasis and/or psoriatic arthritis and the effect of probiotics on the microbiota and severity of psoriasis. Of 1,643 studies, 23 were included (22 observational, 1 interventional). Studies examined the microbiota using culture or 16S rRNA gene sequencing analysis. All culture-based studies identified an increased presence of oral Candida in patients with psoriasis, whereas small variations in the oral microbiota were found in a 16S rRNA gene-based study. All 16S rRNA gene sequencing based studies agreed that the gut microbiota of patients with psoriatic disease differed from that of healthy controls, but the results were heterogeneous. Probiotics were associated with a significant improvement in the severity of psoriasis, but did not change microbiota. Overall, studies lacked relevant inclusion criteria and baseline information. In conclusion, the role of the microbiota in patients with psoriasis requires further investigation using more robust methods.

Plain language summary
Premenstrual syndrome (PMS) is a set of emotional and physical symptoms, which occurs in the days leading up to a woman’s period. The cause of PMS is unknown; however, it is thought that the occurrence of inflammation in the body, an imbalance in the number of free radicals in the body and a lack of dietary antioxidants may all contribute. This systematic review of observational studies aimed to determine if inflammation and imbalanced free radicals contribute to the development of PMS. The results showed that based on 11 studies, there was a small amount of evidence to suggest that increased inflammation and decreased antioxidants is present in women with PMS. However, there was inconsistent results and insufficient data to determine whether free radical imbalance may contribute. It was concluded that further research is required to make firm conclusions on the role of free radicals and inflammation in the development of PMS. This study could be used by healthcare professionals to understand the possible mechanisms behind the development of PMS.
Abstract
Premenstrual syndrome (PMS) is a cyclically occurring combination of various symptoms, leading to decreased life quality among approximately 30% of women of childbearing age. PMS etiology remains unknown; however, there are some suggestions that inappropriate inflammatory response and oxidative stress are involved. This study aimed to systematically review case-control and cross-sectional studies investigating inflammation markers, oxidative stress, and antioxidant status among women with PMS and controls. The study protocol was registered with PROSPERO (no. CRD42020178545), and the authors followed the guidelines for performing a systemic review recommended by Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). By searching PubMed and Scopus databases (up to 8 January 2021), six case-control studies and five cross-sectional studies of medium or high quality were classified to the review. The systematic review included 652 women with PMS and 678 controls, for whom 36 eligible markers were determined. Limited evidence indicates increased levels of inflammatory parameters and suggests decreased antioxidant status in PMS women. Insufficient data with inconsistent results made it impossible to formulate a firm conclusion on the contribution of oxidative stress in PMS occurrence. To acknowledge the role of inflammation, oxidative stress, and antioxidant status in the pathophysiology of PMS, further research with case-control design and large study groups is needed.

Plain language summary
Inflammageing is a term used to describe elevated blood inflammatory markers that leads to frailty and increases an individual’s risk for heart disease, kidney disease and other physical and mental illnesses. Whether inflammageing is causal in heart disease is still uncertain. This large review of 310 papers aimed to understand the causes and role of inflammageing in heart disease and other illnesses associated with ageing. Causes of inflammageing were discussed and mechanisms are not fully understood. Genetic susceptibility, obesity, gut microbiota, gut permeability, when cells can no longer divide, and chronic infections were all implicated. The role of inflammageing in heart disease was a focus and the authors deduced that it was likely to be both causal and a result of heart disease. However, the administration of anti-inflammatories in heart disease has not always proved a successful treatment. Possible causes of inflammageing are likely to be linked and cumulative and although inflammation may cause age related diseases, its role in protecting the body means that its benefits outweigh its consequences. It was concluded that controlling inflammageing may prevent heart disease and other diseases associated with ageing. This study could be used by healthcare professionals to help understand what inflammageing is and its role in age related diseases.
Abstract
Most older individuals develop inflammageing, a condition characterized by elevated levels of blood inflammatory markers that carries high susceptibility to chronic morbidity, disability, frailty, and premature death. Potential mechanisms of inflammageing include genetic susceptibility, central obesity, increased gut permeability, changes to microbiota composition, cellular senescence, NLRP3 inflammasome activation, oxidative stress caused by dysfunctional mitochondria, immune cell dysregulation, and chronic infections. Inflammageing is a risk factor for cardiovascular diseases (CVDs), and clinical trials suggest that this association is causal. Inflammageing is also a risk factor for chronic kidney disease, diabetes mellitus, cancer, depression, dementia, and sarcopenia, but whether modulating inflammation beneficially affects the clinical course of non-CVD health problems is controversial. This uncertainty is an important issue to address because older patients with CVD are often affected by multimorbidity and frailty - which affect clinical manifestations, prognosis, and response to treatment - and are associated with inflammation by mechanisms similar to those in CVD. The hypothesis that inflammation affects CVD, multimorbidity, and frailty by inhibiting growth factors, increasing catabolism, and interfering with homeostatic signalling is supported by mechanistic studies but requires confirmation in humans. Whether early modulation of inflammageing prevents or delays the onset of cardiovascular frailty should be tested in clinical trials.

Intravenous steroids are the first-line therapy for ulcerative colitis (UC) patients who are hospitalised during a severe UC flare-up. In the 40% of patients who don’t respond to steroids, the drugs ciclosporin and infliximab have been found to be efficient in preventing surgery to remove part or all of the colon, but there is a lack of data on the long-term outcomes of using these medications in UC patients. The aim of this study was to assess long-term outcome of patients included in a randomised trial comparing ciclosporin and infliximab. Between 2007 and 2010, 115 patients with UC that did not respond to steroids were randomised to receive ciclosporin or infliximab in association with azathioprine. Patients were followed to January 2015 or death. After a median follow-up of 5.4 years, colectomy-free survival rates at 1 and 5 years were, respectively, 70.9% and 61.5% in patients who received ciclosporin and 69.1% and 65.1% in those who received infliximab. Long-term colectomy-free survival was independent from initial treatment. However, a higher proportion of patients initially treated with ciclosporin needed a new treatment compared with those who received infliximab first. The researchers concluded that these results further confirm a similar efficacy and good safety profiles of both drugs.
Abstract
OBJECTIVE Ciclosporin and infliximab have demonstrated short-term similar efficacy as second-line therapies in patients with acute severe UC (ASUC) refractory to intravenous steroids. The aim of this study was to assess long-term outcome of patients included in a randomised trial comparing ciclosporin and infliximab. DESIGN Between 2007 and 2010, 115 patients with steroid-refractory ASUC were randomised in 29 European centres to receive ciclosporin or infliximab in association with azathioprine. Patients were followed until death or last news up to January 2015. Colectomy-free survival rates at 1 and 5 years and changes in therapy were estimated through Kaplan-Meier method and compared between initial treatment groups through log-rank test. RESULTS After a median follow-up of 5.4 years, colectomy-free survival rates (95% CI) at 1 and 5 years were, respectively, 70.9% (59.2% to 82.6%) and 61.5% (48.7% to 74.2%) in patients who received ciclosporin and 69.1% (56.9% to 81.3%) and 65.1% (52.4% to 77.8%) in those who received infliximab (p=0.97). Cumulative incidence of first infliximab use at 1 and 5 years in patients initially treated with ciclosporin was, respectively, 45.7% (32.6% to 57.9%) and 57.1% (43.0% to 69.0%). Only four patients from the infliximab group were subsequently switched to ciclosporin. Three patients died during the follow-up, none directly related to UC or its treatment. CONCLUSIONS In this cohort of patients with steroid-refractory ASUC initially treated by ciclosporin or infliximab, long-term colectomy-free survival was independent from initial treatment. These long-term results further confirm a similar efficacy and good safety profiles of both drugs and do not favour one drug over the other.

Plain language summary
Musculoskeletal conditions, including osteoarthritis, inflammatory arthritis, musculoskeletal injuries, gout and metabolic bone disease, are the most common cause of chronic disability worldwide. Treatment with analgesic and/or anti-inflammatory medication carries a significant risk of side effects. Botanical extracts are also commonly used for the management of musculoskeletal disorders, and in addition to having less side effects they may have a beneficial effect on the course of the disease. This review focuses on the use of boswellic acids (BA, from Frankincense, Boswellia serrata and Boswellia carterii) in the treatment of musculoskeletal conditions. In pre-clinical experiments, BAs have been shown to be anti-inflammatory and improve antioxidant status. In several clinical trials BSE was superior to placebo in reducing pain and increasing functionality in osteoarthritis. BSE are poorly absorbed, and both clinical and pre-clinical research has shown that a combination of BAs with lecithin (Casperome®) enhances absorption and bioavailability. Casperome® has been investigated in a number of clinical trials and has been shown to be of benefit in tendinopathies (inflammation of the elbow and Achilles tendon), radiculopathies (pinched nerves), sprained ankles and sports injuries. The authors conclude that Casperome® is a promising remedy as part of an integrated approach to musculoskeletal disorders.
Abstract
Standard pharmacological treatment of musculoskeletal conditions is often associated with relevant side effects. Botanical preparations endowed with a good tolerability profile, therefore, could have a role in the management of these disorders. Among different natural products, Boswellia serrata extracts have long been used for the treatment of musculoskeletal disorders, given their marked anti-inflammatory activity and their ability to promote tissue regeneration. However, standard preparations of Boswellia serrata show overall modest pharmacokinetic properties, a limitation which may ultimately lead to reduced efficacy. In an effort to improve the pharmacokinetic properties, Casperome®, a lecithin-based formulation of Boswellia serrata extract representing the whole natural bouquet, has been developed. This formulation was effective in the treatment of Achilles tendonitis, epicondylitis, radiculopathies, ankle sprains and sport injuries as shown in several clinical studies, the majority of which with a randomized design and all evaluating a number of well-recognized parameters of efficacy for the therapy of musculoskeletal disorder. All studies were consistent in showing a prompt decrease of pain and improvement of functionality of the affected area after supplementation with Casperome®, without any relevant adverse effect. Remarkably, these symptomatic improvements were paralleled by reduced plasmatic levels of inflammatory markers and by a diminished need for rescue analgesics. On these bases, Casperome® may have a role in the treatment of musculoskeletal disorders. Clinical studies in other similar conditions (e.g., osteoarthritis) appear warranted to further investigate the efficacy of this botanical product in more specific settings.

AndoSanTM is a medicinal mushroom supplement based on Agaricus Blazei Murrill (ABM), but also contains Hericium erinaceus (lion’s mane, 14.7%) and Grifola frondosa (Maitake, 2.9), and contains immune modulatory beta-glucans as well as other bioactive compounds. This single-centre randomised two-armed patient-blinded study was designed to determine whether daily oral intake of AndoSanTM could improve clinical symptoms, fatigue and quality of life in patients with Crohn’s Disease (CD). Patients received either AndoSanTM 60ml per day or placebo for 21 days and were evaluated before start of treatment and at day 14 and 21. Outcome measures were the Crohn’s Disease Activity Index (SCDAI), the self-reported health-related quality of life (HRQoL), a fatigue questionnaire, blood parameters and faecal calprotectin (a marker for intestinal inflammation). 25 patients in each study arm completed the trial and were included in study analysis. There was a statistically significant improvement inf SCDAI in the AndoSanTM group, in particular for number of liquid stools and pain, but not the placebo group, although the difference between the groups was not statistically significant. There were no statistically significant differences for fatigue, quality of life, blood tests or calprotectin. No adverse effects were reported. The authors conclude that AndoSanTM could be safe to complement conventional medication to relieve symptoms in CD patients.
Abstract
BACKGROUND Ingestion of AndoSanTM, based on the mushroom Agaricus blazei Murill, has previously shown an anti-inflammatory effect through reduction of pro-inflammatory cytokines in healthy individuals and patients with Crohn's disease (CD). In this randomized single-blinded placebo-controlled study we examined whether intake of AndoSanTM also resulted in clinical effects. METHODS AND FINDINGS 50 patients with symptomatic CD were randomized for oral daily consumption of AndoSanTM or placebo for a 21-day experimental period, in this per-protocol study. Patients reported validated scores for symptoms, fatigue and health related quality of life (HRQoL) at days 0, 14 and 21. Fecal calprotectin and general blood parameters were also analyzed. In the AndoSanTM group (n = 25) symptoms improved from baseline (day 0) to days 14 and 21, with respective mean scores (95% CI) of 5.52 (4.64-6.40), 4.48 (3.69-5.27) and 4.08 (3.22-4.94) (p<0,001). We found significant improvements in symptom score for both genders in the AndoSanTM group, and no significant changes in the placebo (n = 25) group. There were however no significant differences between the groups (p = 0.106), although a marginal effect in symptom score for men (p = 0.054). There were comparable improvements in physical, mental and total fatigue for both groups. HRQoL versus baseline were at day 21 improved for bodily pain and vitality in the AndoSanTM group and for vitality and social functioning in the placebo group. No crucial changes in general blood samples and fecal calprotectin were detected. CONCLUSIONS The results from this single-blinded randomized clinical trial shows significant improvement on symptoms, for both genders, in the AndoSanTM group, but no significant differences between the study groups. The results on fatigue, HRQoL, fecal calprotectin and blood samples were quite similar compared with placebo. The patients did not report any harms or unintended effects of AndoSanTM. CD patients with mild to moderate symptoms may have beneficiary effects of AndoSanTM as a safe supplement in addition to conventional medication. TRIAL REGISTRATION ClinicalTrials.gov NCT01496053.

This single-centre randomised two-armed patient-blinded study was designed to determine whether daily oral intake of AndoSanTM could improve clinical symptoms, fatigue and quality of life in patients with mild to moderate ulcerative colitis (UC). Patients received either AndoSanTM 60ml per day or placebo for 21 days and were evaluated before start of treatment and at day 14 and 21. Outcome measures were a modified Clinical Activity Index (CAI)), the self-reported health-related quality of life (HRQoL), a fatigue questionnaire, blood parameters and faecal calprotectin (a marker for intestinal inflammation). 24 patients in the AndoSanTM arm and 26 in the placebo arm completed the trial and were included in study analysis. Compared with baseline only the patients in the AndoSan™ group reported significant reductions of symptoms, fatigue and quality of life which were significantly better than in the placebo group. There were no significant changes in blood parameters in either group. There was no change in calprotectin in the AndoSanTM group but a significant worsening in the placebo group. No adverse effects were reported. A limitation of the study is that it was only blinded to the patients but not to the investigators. The authors conclude that AndoSan™ may be beneficial as a supplement to conventional medication in patients with mild to moderate UC.
Abstract
BACKGROUND Ingestion of AndoSan™, based on the mushroom Agaricus blazei Murill, has previously been shown to exhibit anti-inflammatory effects because of reduction of pro-inflammatory cytokines in healthy individuals and patients with ulcerative colitis. In this randomized single-blinded placebo controlled study we examined whether intake of AndoSan™ also resulted in clinical effects. METHODS AND FINDINGS 50 patients with symptomatic ulcerative colitis were block-randomized and blinded for oral daily intake of AndoSan™ or placebo for the 21 days' experimental period. The patients reported scores for symptoms, fatigue and health related quality of life (HRQoL) at days 0, 14 and 21. Fecal calprotectin and general blood parameters were also analyzed. In the AndoSan™ group (n = 24) symptoms improved from baseline (day 0) to days 14 and 21, with respective mean scores (95% CI) of 5.88 (4.92-6.83), 4.71 (3.90-5.52) (p = 0.002) and 4.50 (3.70-5.30) (p = 0.001). Corresponding improved mean scores (±SD) for total fatigue were 16.6 (5.59), 14.1 (4.50) (p = 0.001) and 15.1 (4.09) (p = 0.023). These scores in the placebo group (n = 26) were not improved. When comparing the two study groups using mixed model statistics, we found significant better scores for the AndoSan™-patients. HRQoL for dimensions bodily pain, vitality, social functioning and mental health improved in the AndoSan™ group. There were no alterations in general blood samples and fecal calprotectin. CONCLUSIONS Beneficiary effects on symptoms, fatigue and HRQoL from AndoSan™ consumption were demonstrated in this per-protocol study, supporting its use as a supplement to conventional medication for patients with mild to moderate symptoms from ulcerative colitis. The patients did not report any harms or unintended effects of AndoSan™ in this study. TRIAL REGISTRATION ClinicalTrials.gov NCT01496053.
