Effect of long-term orlistat treatment on serum levels of advanced glycation end-products in women with polycystic ovary syndrome
Abstract
UNLABELLED: BACKGROUND Women with polycystic ovary syndrome (PCOS) exhibit elevated serum advanced glycation end-products (AGE) compared with healthy subjects. Short-term administration of orlistat has been shown to reduce the postmeal increase in serum AGE levels in women with PCOS and in controls. OBJECTIVE: To evaluate the long-term effect of orlistat and a low-calorie diet on serum AGE levels, and on the hormonal and metabolic profile of obese PCOS and normal women. DESIGN: A clinical trial of 6 months of orlistat administration with an energy-restricted diet [basic metabolic rate (BMR) 600 kcal/day] in all subjects. SUBJECTS: Twenty-nine women with PCOS [aged 27.52 +/- 5.77 years; body mass index (BMI) 35.43 +/- 5.31 kg/m(2)] and 18 controls (aged 32.06 +/- 5.64 years; BMI 36.39 +/- 6.47 kg/m(2)). MEASUREMENTS: Serum AGE levels (U/ml), hormonal and metabolic profile. RESULTS: PCOS and controls did not differ in BMI (P = 0.58), waist-to-hip ratio (WHR) (P = 0.44), fasting insulin concentration (P = 0.45) and glucose-to-insulin ratio (GIR) (P = 0.34). PCOS women exhibited statistically higher AGE (P < 0.001) and testosterone levels (P < 0.001) compared with controls. After 6 months of orlistat treatment, AGE levels showed a statistically significant decrease in both groups (PCOS: baseline 9.08 +/- 1.84, post-orlistat 8.56 +/- 1.95, P = 0.001; controls: baseline 5.02 +/- 0.62, post-orlistat 4.91 +/- 0.69, P = 0.03), independently of the BMI reduction in the PCOS group. A significant reduction was observed in BMI (PCOS: P < 0.001; controls: P < 0.001), WHR (PCOS: P = 0.002; controls: P = 0.04), fasting insulin (PCOS: P < 0.001; controls: P = 0.008), and testosterone concentrations in PCOS (P < 0.001). SHBG concentration (PCOS: P = 0.004; controls: P = 0.008) and GIR (PCOS: P < 0.001; controls: P = 0.03) were significantly increased. A significant improvement was also observed in insulin resistance indices post-treatment in both groups. CONCLUSIONS: Our data suggest that orlistat has a beneficial effect in reducing elevated AGE levels and improving the hormonal and metabolic profile in women with PCOS after 6 months of treatment, independently of BMI changes.

One study with a hypocaloric diet + anti-obesity drug (Orlistat) intervention reported a statistically significant difference in SHBG between groups (p < 0.05) following the intervention; however, there was also a statistically significant difference in SHBG at baseline between the groups (p < 0.05).
“One study with a hypocaloric diet + anti-obesity drug (Orlistat) intervention [30] reported a statistically significant difference between groups (p < 0.05) following the intervention; however, there was also a statistically significant difference in SHBG at baseline between the groups (p < 0.05).”

One study with a hypocaloric diet + an anti-obesity drug intervention (Orlistat), and another study with an anti-obesity drug intervention (Orlistat) + a hypocaloric diet + exercise intervention, reported a statistically significant difference in total testosterone following intervention between the two study groups, with the non-PCOS group having lower values in both studies.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
