Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
4 weeks oral ingestion of both :
1. soluble fibre in water (5 gm in 200 ml warm water once daily).
2. two probiotic capsules per day (Metagenics Ultra Flora Restore). Each capsule contains 25 billion organisms, including 12.5 Billion Lactobacillus acidophilus NCFM, 12.5 Billion bifidobacterium Lactis Bi-07, 5 Billion lactobacilus rhamnosus and 5 Billion Saccharomyces cerevisiae organisms

Outcomes
Primary outcome [1] 288323 0
To determine if fibre/ probiotic supplementation can reduce inflammation in women with PCOS. The two chosen markers of inflammation are serum C-Reactive Protein (CRP) and Lipopolysaccaride Binding Protein (a marker of immuno-stimulatory endotoxin exposure), assayed by an ELISA.
Timepoint [1] 288323 0
Inflammatory markers will be assessed at study entry and then again 4 weeks later
Secondary outcome [1] 299851 0
1. Reproductive hormones Anti Mullarian Hormone (AMH), Testosterone, sex hormone binding globulin (SHBG).
AMH will be assessed "in house" using an ELISA and testosterone/ SHBG measured by a commercial pathology laboratory.
Timepoint [1] 299851 0
Study entry and then again 4 weeks later (completion of 4 week course fibre/ probiotic)
Secondary outcome [2] 299852 0
2. Blood biochemistry including glucose, insulin, calculated insulin resistance, cholesterol, low and high density lipoproteins (LDL and HDL), homocysteine. These will all be assessed by a commercial pathology laboratory.
Timepoint [2] 299852 0
Study entry and then again 4 weeks later (completion of 4 week course fibre/ probiotic)
Secondary outcome [3] 299853 0
3. Assessment of ovulatory function based on menstrual calender, serum estradiol and progesterone measurements. These will be assessed using a ADVIAR Centaur XP assay platform system (Siemens Healthcare Diagnostics)
Timepoint [3] 299853 0
Entry and day 21 of the study. If ovulation has not been confirmed (serum progesterone > 15 nmol/l) on day 21 sample, a further estrogen and progesterone assessement will be taken on days 28, 35 and 42. If progesterone exceeds 15 nmol/l on either day 28 or 35, nil further blood tests will be taken. The timing of onset of the menstrual period will be followed out to 6 weeks (42 days) after commencement of fibre/ probiotic treatment.
Secondary outcome [4] 299854 0
4. Assessment of gastrointestinal function. This will be done using the Rome III criteria for the diagnosis of Irritable Bowel Syndrome (IBS) and the Birmingham IBS symptom severity questionnaire.
Timepoint [4] 299854 0
Screening examination before initiation of investigational treatment (fibre/ probiotic) and 28 days later.
Secondary outcome [5] 299855 0
5. Anthropometric assessment. Body mass Index (height/ weight), percentage body fat by bioelectrical impedance analyzer, waist circumference

Study entry and day 28 of study
Secondary outcome [6] 299857 0
6. Diet assessment by 3 day food frequency assessment

Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants with PCOS and IBS will be invited by newspaper and online advertisements to be screened for their involvement in the trial. Provided they meet the inclusion/ exclusion criteria they will all then be allocated to 4 weeks (28 days) of fibre and probiotic supplementation. No placebo will be used and therefore allocation concealment is not required.
