Randomized Controlled Trial of Preconception Interventions in Infertile Women With Polycystic Ovary Syndrome.

ABSTRACT: Lifestyle modification is recommended in women with polycystic ovary syndrome (PCOS) prior to conception but there are few randomized trials to support its implementation or benefit.This study aimed to determine the relative efficacy of preconception intervention on reproductive and metabolic abnormalities in overweight/obese women with PCOS.This was a randomized controlled trial of preconception and infertility treatment at Academic Health Centers in women with infertility due to PCOS, age 18-40 y and body mass index 27-42 kg/m(2).Women were randomly assigned to receive either 16 weeks of 1) continuous oral contraceptive pills (OCPs) (ethinyl estradiol 20 mcg/1 mg norethindrone acetate) ("OCP"); 2) lifestyle modification consisting of caloric restriction with meal replacements, weight loss medication (either sibutramine, or orlistat), and increased physical activity to promote a 7% weight loss ("Lifestyle"); or 3) combined treatment with both OCP and lifestyle modification ("Combined"). After preconception intervention, women underwent standardized ovulation induction with clomiphene citrate and timed intercourse for four cycles. Pregnancies were followed with trimester visits until delivery.Weight, ovulation, and live birth were measured.We consented 216 and randomly assigned 149 women (Lifestyle: n = 50; OCP: n = 49; Combined: n = 50). We achieved significant weight loss with both Lifestyle (mean weight loss, -6.2%; 95% confidence interval (CI), -7.4--5.0; and Combined (mean weight loss, -6.4%; 95% CI, -7.6--5.2) compared with baseline and OCP (both P < .001). There was a significant increase in the prevalence of metabolic syndrome at the end of preconception treatment compared with baseline within OCP (odds ratio [OR, 2.47; 95% CI, 1.42-4.27) whereas no change in metabolic syndrome was detected in the Lifestyle (OR, 1.18; 95% CI, 0.63-2.19) or Combined (OR, 0.72; 95% CI, 0.44-1.17) groups. Cumulative ovulation rates were superior after weight loss: OCP, 46%; Lifestyle, 60%; and Combined, 67% (P < .05). Live birth rates were OCP, 12%; Lifestyle, 26%; and Combined, 24% (P = .13).A preconception weight loss intervention eliminates the adverse metabolic oral contraceptive effects and, compared with oral contraceptive pretreatment, leads to higher ovulation rates.

Project description:BackgroundWomen with obesity and infertility are counseled to lose weight prior to conception and infertility treatment to improve pregnancy rates and birth outcomes, although confirmatory evidence from randomized trials is lacking. We assessed whether a preconception intensive lifestyle intervention with acute weight loss is superior to a weight neutral intervention at achieving a healthy live birth.Methods and findingsIn this open-label, randomized controlled study (FIT-PLESE), 379 women with obesity (BMI ≥ 30 kg/m2) and unexplained infertility were randomly assigned in a 1:1 ratio to 2 preconception lifestyle modification groups lasting 16 weeks, between July 2015 and July 2018 (final follow-up September 2019) followed by infertility therapy. The primary outcome was the healthy live birth (term infant of normal weight without major anomalies) incidence. This was conducted at 9 academic health centers across the United States. The intensive group underwent increased physical activity and weight loss (target 7%) through meal replacements and medication (Orlistat) compared to a standard group with increased physical activity alone without weight loss. This was followed by standardized empiric infertility treatment consisting of 3 cycles of ovarian stimulation/intrauterine insemination. Outcomes of any resulting pregnancy were tracked. Among 191 women randomized to standard lifestyle group, 40 dropped out of the study before conception; among 188 women randomized to intensive lifestyle group, 31 dropped out of the study before conception. All the randomized women were included in the intent-to-treat analysis for primary outcome of a healthy live birth. There were no significant differences in the incidence of healthy live births [standard 29/191(15.2%), intensive 23/188(12.2%), rate ratio 0.81 (0.48 to 1.34), P = 0.40]. Intensive had significant weight loss compared to standard (-6.6 ± 5.4% versus -0.3 ± 3.2%, P < 0.001). There were improvements in metabolic health, including a marked decrease in incidence of the metabolic syndrome (baseline to 16 weeks: standard: 53.6% to 49.4%, intensive 52.8% to 32.2%, P = 0.003). Gastrointestinal side effects were significantly more common in intensive. There was a higher, but nonsignificant, first trimester pregnancy loss in the intensive group (33.3% versus 23.7% in standard, 95% rate ratio 1.40, 95% confidence interval [CI]: 0.79 to 2.50). The main limitations of the study are the limited power of the study to detect rare complications and the design difficulty in finding an adequate time matched control intervention, as the standard exercise intervention may have potentially been helpful or harmful.ConclusionsA preconception intensive lifestyle intervention for weight loss did not improve fertility or birth outcomes compared to an exercise intervention without targeted weight loss. Improvement in metabolic health may not translate into improved female fecundity.Trial registrationClinicalTrials.gov NCT02432209.

Project description:BACKGROUND:Traditional Chinese medicine (TCM) usually involves syndrome differentiation and treatment. Acupuncture, one form of TCM, requires the selection of appropriate acupoints and needling techniques, but many clinical trials on acupuncture have used fixed acupuncture protocols without accounting for individual patient differences. We have designed a multicenter randomized controlled trial (RCT) to evaluate whether personalized or fixed acupuncture increases the likelihood of live births in infertile women with polycystic ovary syndrome (PCOS) compared with letrozole or placebo letrozole. We hypothesize that letrozole is more effective than personalized acupuncture, which in turn is more effective than fixed acupuncture, and that placebo letrozole is the least effective intervention. Moreover, we hypothesize that personalized acupuncture is more likely to reduce the miscarriage rate and the risk of pregnancy complications compared with letrozole. METHODS/DESIGN:The study is designed as an assessor-blinded RCT. A total of 1100 infertile women with PCOS will be recruited from 28 hospitals and randomly allocated to 4 groups: personalized acupuncture, fixed acupuncture, letrozole, or placebo letrozole. They will receive treatment for 16?weeks, and the primary outcome is live birth. Secondary outcomes include ovulation rate, conception rate, pregnancy rate, pregnancy loss rate, changes in hormonal and metabolic parameters, and changes in quality of life scores. Adverse events will be recorded throughout the trial. All statistical analyses will be performed using IBM SPSS Statistics version 21.0 software (IBM Corp., Armonk, NY, USA), and a P value <?0.05 will be considered statistically significant. DISCUSSION:This study will be the first multicenter RCT to compare the effect of personalized or fixed acupuncture with letrozole or placebo letrozole on live birth in infertile women with PCOS. The findings will inform whether personalized acupuncture therapy can be considered an alternative treatment to improve the live birth rate in infertile women with PCOS.
