Brief summary
The effect of Lactobacillus rhamnosus supplementation on body weight, hyperandrogenism and insulin resistance in overweight and obesity women with Polycystic Ovary Syndrome will be analysed.
Interventions
DIETARY_SUPPLEMENTLactobacillus group
Nutrition intervention focused on the treatment of insulin resistance + Lactobacillus rhamnosus supplementation (6x10 9 of lactobacillus rhamnosus x 2 times a day) (35 people).
DIETARY_SUPPLEMENTDietary group

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Blood lipid profile: low density lipoprotein | 20 weeks | Low density lipoprotein LDL (mg/dL) will be measured at baseline and after 20 weeks of the intervention |
| Blood lipid profile: cholesterole | 20 weeks | Cholesterole (mg/dL) will be measured at baseline and after 20 weeks of the intervention |
| Blood lipid profile: triglicerydes | 20 weeks | Triglicerydes (mg/dL) will be measured at baseline and after 20 weeks of the intervention |
| Blood lipid profile: high density lipoprotein | 20 weeks | High density lipoprotein HDL (mg/dL) will be measured at baseline and after 20 weeks of the intervention |
| Insulin Resistance | 20 weeks | Fasting insulin concentration (uU/ml) will be measured before and after 2 hours of 75g glucose drink. Insulin resistance will be measured before and after 20 weeks of the intervention. |
| Oral glucose test OGTT | 20 weeks | Fasting glucose concentration (mg/dL) will be measured before and after 2 hours of 75g glucose drink. OGTT will be measured before and after 20 weeks of the intervention. Fating glucose and fasting insulin concentrations will be combined to report HOMA-IR index (homeostatic model assessment of insulin resistance). |
| Testosterone | 20 weeks | Testosterone (ng/mL) concentrations will measured at baseline and after 20 weeks of the intervention. Results of testosterone level and SHBG level will be combined to report FAI index (index of free androgen). |
| DHEA-SO4 | 20 weeks | DHEA-SO4 (umol/L) concentrations will measured at baseline and after 20 weeks of the intervention. Results of testosterone level and SHBG level will be combined to report FAI index (index of free androgen). |
| SHBG | 20 weeks | SHBG (nmol/L) concentrations will measured at baseline and after 20 weeks of the intervention. Results of testosterone level and SHBG level will be combined to report FAI index (index of free androgen). |
| Free androgen index FAI | 20 weeks | Results of testosterone level and SHBG level will be combined to report FAI index (index of free androgen). |
| Body weight | 20 weeks | Body weight (kg) will be assessment at baseline and after 20 weeks of the intervention. |
| Body height | Baseline | Body height (cm) will be assessment at baseline of the intervention. |
| Body composition | 20 weeks | Fat mass (%), fat free mass (%) will be assessment at baseline and after 20 weeks of the intervention. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Assessment of B-glucuronidase and B-glucosiadase activity | 20 weeks | B-glucuronidase and B-glucosiadase activity in stoolen sample will be assessment at baseline and after 20 weeks of the intervention |
| Assessment of short-chain fatty acids | 20 weeks | Assessment of short-chain fatty acids will be assessment at baseline and after 20 weeks of the intervention |
| Assessment of qualitative and quantitative of the microbiome | 20 weeks | Qualitative and quantitative determination of the composition of gut microbiota will be assessment at baseline and after 20 weeks of the intervention |
