Outcome Measures

Primary Outcomes (3)

  • Change from baseline microbiota composition in women suffering from UUI and OAB at three months follow-up

    The microbiota composition is analyzed using sequencing of bacterial DNA. We are investigating the urinary, vaginal and gut microbiota. In women with urge urinary incontinence (UUI) and overactive bladder (OAB) receiving RCE (symptomatic RCE), a possible change in the urinary, vaginal and fecal microbiota composition from baseline to three month follow-up, compared to controls receiving placebo (symptomatic PL) are investigated. Symptomatic RCE from baseline to follow-up vs. Symptomatic PL from baseline to follow-up

    From baseline to three months follow-up

  • Change in baseline microbiota composition at three months follow-up

    The microbiota composition is analyzed using sequencing of bacterial DNA. Comparison of healthy women without bladder symptoms receiving RCE (healthy RCE) at baseline to three months follow-up compared to controls (healthy PL) from baseline to follow-up. Healthy RCE from baseline to follow-up vs. Healthy PL from baseline to follow-up

    From baseline to three months follow-up

  • Difference in baseline microbiota composition between women with and without UUI and OAB

    The microbiota composition is analyzed using sequencing of bacterial DNA. Is there a difference in the urinary, vaginal and gut microbiota in women with and without urge urinary incontinence (UUI) and overactive bladder (OAB) at baseline? Symptomatic PL baseline vs. Healthy PL baseline

    Baseline

Secondary Outcomes (9)

  • Comparison of the urinary, vaginal, and fecal microbiota

    Baseline

  • Change in overactive bladder symptoms from baseline in women suffering from UUI and OAB at three months follow-up

    From baseline to three months follow-up

  • Change in urinary incontinence symptoms from baseline in women suffering from UUI and OAB at three months follow-up

    From baseline to three months follow-up

  • Change in blood estrogen levels from baseline to three months follow-up

    From baseline to three months follow-up

  • Change in blood isoflavone levels from baseline to three months follow-up

    From baseline to three months follow-up

  • +4 more secondary outcomes

Study Arms (4)

Symptomatic RCE

EXPERIMENTAL

Bladder symptomatic group receiving red clover extract containing the two isoflavones formononetin and biochanin A. Isoflavone amount is 57.45 mg isoflavones daily (55.84 mg aglycones daily), in 70 ml red clover extract (35 ml twice daily, morning and evening with a meal)

Dietary Supplement: Red Clover Extract (RCE)

Healthy RCE

EXPERIMENTAL

Healthy group without bladder symptoms receiving red clover extract containing the two isoflavones formononetin and biochanin A. Isoflavone amount is 57.45 mg isoflavones daily (55.84 mg aglycones daily), in 70 ml red clover extract (35 ml twice daily, morning and evening with a meal)

Dietary Supplement: Red Clover Extract (RCE)

Symptomatic PL

PLACEBO COMPARATOR

Bladder symptomatic group receiving placebo

Other: Placebo (PL)

Healthy PL

PLACEBO COMPARATOR

Healthy group without bladder symptoms receiving placebo

Other: Placebo (PL)

Interventions

Red Clover Extract (RCE)DIETARY_SUPPLEMENT

Red clover extract containing isoflavones Formononetin and biochanin A together with a heterogenous culture of probiotic lactic acid bacteria, and a natural sugar free raspberry/orange flavor. Isoflavone amount is 57.45 mg isoflavones daily (55.84 mg aglycones daily), in 70 ml red clover extract (35 ml twice daily, morning and evening together with a meal)

Healthy RCESymptomatic RCE

Placebo containing water, brown coloring, and natural sugar free raspberry/orange flavor.
