Study summary

The present studies demonstrated that pro-inflammation, systemic oxidative stress and dysfunction in the brain-gut microbiota axis were involved in Alzheimer's disease (AD) pathogenesis. These results implied the decreased regulation of inflammation-associated risk and microbiota in AD patients could provide the novel strategies for combating the disease. This study was designed to assess the addition of Wismemo in treatment of cholinesterase inhibitors (such as donepezil, rivastigmine, galantamine) in the AD patients.

Read the detailed description

Previously studies have shown some probiotics could improve stress-related diseases such as anxiety, autism, depression and schizophrenia might be through regulating brain-gut microbiota axis, pro-inflammation and oxidative stress. Although recent clinical study indicated that mix-probiotics (containing Lactobacillus acidophilus, Lactobacillus casei, Bifidobacteria bifidum and Lactobacillus fermentum) consumption could improve the cognitive function of dementia patients.

In this clinical study, whether Genmont specific strain probiotics could improve the clinical syndromes and delay worsens in Alzheimer's dementia patients with regular treatment were clarified. A Randomized, double-blind, placebo-controlled clinical trial would be carried out. AD's patients with regular treatment are additive consumption multi-strain probiotic supplement (Wismemo). Half of participants will receive Wismeno and regular treatment in combination, while the other half will receive placebo and regular treatment in combination. To evaluate of the effect of probiotic supplementation on cognitive, emotional and related status on Alzheimer's dementia patients.

What researchers measure

Primary outcomes

  1. Mini-Mental State Examination (MMSE) for efficacy

    Change in cognitive status was evaluated using the Mini-Mental State Examination (MMSE). MMSE will be assessed at baseline and after intervention. The maximum score is 30. If the scores are less than 24, it would be assessed to the mild dementia. If the scores are less than 16, it would be assessed to the severe dementia.

    Time frame: 0, 3, 6 months

Secondary outcomes

  1. Neuropsychiatric Inventory (NPI) for efficacy and quality of life

    Change from baseline in scores of psychosocial scale and caregiver distress was evaluated using the neuropsychiatric Inventory (NPI) by 12 items respectively. The 12 items include delusion, fantasy, depression, anxiety, etc., The maximum score of psychosocial scale is 144. The maximum score of caregiver distress is 60. Change in scores of total and each item will be assessed at baseline and after intervention.

    Time frame: 0, 3, 6 months

  2. Change from baseline in levels of peroxidation and antioxidant profiles (MDA and TAC)

    Serum levels may possibly decrease peroxidation or increase antioxidant effects of probiotics.

    Time frame: 0 and 6 months

  3. Change from baseline in levels of inflammatory markers (IL-10,IL-6, IL-1 beta, TNF-alpha and TGF-beta)

    Serum levels may possibly decrease inflammatory or increase anti-inflammatory effects of probiotics.

    Time frame: 0 and 6 months

  4. Change from baseline in levels of inflammatory markers (hs-CRP)

    Serum levels may possibly decrease inflammatory effects of probiotics.

    Time frame: 0 and 6 months

  5. Change from baseline in levels of blood sugar (HbA1c)

    Serum levels may possibly decrease high blood sugar effect of probiotics.

    Time frame: 0 and 6 months

  6. Change from baseline in levels of insulin resistance profile (FPG, insulin and HOMA-IR)

    Serum levels may possibly decrease insulin resistance effect of probiotics.

    Time frame: 0 and 6 months

  7. Gut microbiota for efficacy

    Stool samples at baseline and after intervention will be collected. Gut microbiota profile will be assessed.

    Time frame: 0 and 6 months

  8. Mini-Nutritional Assessment (MNA) for feasibility and efficacy

    Change in Mini-Nutritional Assessment (MNA) MNA will be assessed at baseline and after intervention. The maximum score is 14. If the scores are 12-14, it would be assessed to normal malnutrition. If the scores are less than 12, it would be assessed to have the risk of malnutrition. If the scores are less than 8, it would be assessed to the malnutrition.

    Time frame: 0, 3, 6 months

If the scores are 0-5, it would be assessed to good. If the scores are 6-9, it would be assessed to mild emotional distress. If the scores are 10-14, it would be assessed to moderate emotional distress. If the scores are greater than or equal t 15, it would be assessed to severe emotional distress.
