An imbalance in the gut bacteria has been shown to be involved in the development of inflammatory skin conditions such as dermatitis and psoriasis. Seaweed extract known as sulphated xylorhamnoglucuronan (SXRG84) is a novel prebiotic, which may act to promote the growth of good gut microbiota and therefore be of benefit to people with skin conditions. This randomised control trial of 50 individuals with inflammatory skin conditions aimed to determine the effect of SXRG84 on symptoms. The results showed that overall, there were no differences between the treatments, however there is a subset of individuals who respond to SXRG84 and show significantly decreased inflammation in the blood and improved skin symptoms. 27% of 38 individuals with psoriasis and the two individuals with eczema indicated improvements, although individuals with rosacea, dermatitis, palmar plantar keratoderma, disseminated superficial actinic porokeratosis and palmar plantar psoriasis showed no improvements. It was concluded that amongst responders, SXRG84 for 6-weeks may improve inflammation and skin symptoms. This study could be used by healthcare professionals to understand that a personal approach is required for the management of skin conditions and that individuals with psoriasis and eczema may positively respond to SXRG84 in their diet.
Abstract
We examined the effect of a dietary seaweed extract-sulfated xylorhamnoglucuronan (SXRG84)-on individuals with inflammatory skin conditions. A subgroup analysis of a larger trial was undertaken, where 44 participants with skin conditions were enrolled in a double-blind placebo-controlled crossover design. Subjects ingested either SXRG84 extract (2 g/day) for six weeks and placebo for six weeks, or vice versa. At baseline, six- and twelve-weeks inflammatory markers and the gut microbiota were assessed, as well as skin assessments using the dermatology quality of life index (DQLI), psoriasis area severity index (PASI) and visual analogue scales (VAS). There were significant differences at weeks six and twelve for pro-inflammatory cytokines IFN-γ (p = 0.041), IL-1β (p = 0.030), TNF-α (p = 0.008) and the anti-inflammatory cytokine IL-10 (p = 0.026), determined by ANCOVA. These cytokines were all significantly higher at six weeks post placebo compared to twelve weeks post placebo followed by SXRG84 treatment. A total of 23% of participants reported skin improvements, as measured by VAS (mean difference 3.1, p = 0.0005) and the DQLI score (mean difference -2.0, p = 0.049), compared to the 'non-responders'. Thus, the ingestion of SXRG84 for 6 weeks reduced inflammatory cytokines, and a subset of participants saw improvements.

Plain language summary
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
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.
