LpD3.5 Intervention Study in Older Adults- LISA-I Trial

This randomized placebo-controlled clinical study, called the LpD3.5 Intervention Study in Older Adults (LISA), aims to evaluate whether a heat-inactivated postbiotic of human origin (LpD3.5) can serve as a non-pharmacological intervention to reduce gut permeability and inflammation in older adults with mild cognitive impairment (MCI). The study will assess the effects of LpD3.5 supplementation on markers associated with gut health, inflammation, microbiome composition, and cognitive function. Participants aged 60 years or older with clinically diagnosed MCI will receive either LpD3.5 capsules or placebo capsules for 60 days, followed by a 30-day follow-up period. Biological samples and clinical assessments will be collected to evaluate changes in gut permeability, inflammatory markers, microbiome characteristics, and cognitive outcomes. The findings from this study may provide insight into the potential role of postbiotics as a dietary intervention to improve gut health and related outcomes in older adults with MCI.

Probiotics Use and Preventing Gastrointestinal Symptoms in People Living With Overweight and Obesity.

Inflammatory bowel disease (IBD) affects over 6.8 million people worldwide, with current treatments often causing side effects and poor patient compliance. Dysbiosis of gut microbiota is a key factor, and while probiotics are considered safe and beneficial, conventional strains fail to function effectively during active inflammation due to high iron levels in the gut. Streptococcus thermophilus (FX856), unlike traditional probiotics, can thrive in this iron-rich environment, promoting mucosal healing. A 2-way crossover intervention study will be conducted with FX856 supplementation in overweight and obese individuals who often exhibit mild gut inflammation by measuring faecal calprotectin and systemic inflammatory markers.
