Treatment of unfavorable bleeding patterns in contraceptive implant users: a randomized clinical trial of curcumin.

BACKGROUND: Some users of the etonogestrel contraceptive implant experience bothersome bleeding, which can reduce contraceptive satisfaction and continuation. Few strategies exist to manage this bleeding. The exact mechanism of progestin-induced bleeding is unknown, but it is likely multifactorial (eg, impaired angiogenesis, "leaky" fragile vasculature, and inflammation). Curcumin, the active ingredient in turmeric, has anti-inflammatory, antiproliferative, and antiangiogenic properties, which may make it a useful agent for implant-associated bothersome bleeding. OBJECTIVE: This study aimed to evaluate whether curcumin decreases frequent or prolonged bleeding or spotting in contraceptive implant users. STUDY DESIGN: The study was a randomized, double-blind, placebo-controlled trial. Here, etonogestrel implant users with frequent or prolonged bleeding or spotting were enrolled and randomized to either 600-mg Theracurmin HP (Immunovites, Las Vegas, NV) or placebo daily for 30 days. The term "frequent" was defined as ≥2 independent bleeding or spotting episodes, and the term "prolonged" was defined as ≥7 consecutive days of bleeding or spotting in a 30-day interval. Implant use was confirmed by clinical examination and negative gonorrhea and chlamydia and pregnancy tests. Enrolled participants initiated study treatment after 3 consecutive days of bleeding or spotting; if no bleeding or spotting occurred within 30 days of enrollment, the participants were withdrawn from the study. Study treatments were encapsulated to maintain a similar appearance. Participants used text messages to record daily bleeding patterns and study drug compliance. Bleeding was defined as a day that required the use of protection with a pad, tampon, or liner, and spotting was defined as a day with minimal blood loss that did not require the use of any protection. Our primary outcome was the total number of days without bleeding or spotting during the 30 days of study drug or placebo exposure. The secondary outcomes included total number of bleeding-free days, bleeding episodes, and satisfaction. A sample size of 22 per group provided 80% power at an alpha level of .05 to demonstrate a 6-day difference between groups. RESULTS: From February 2021 to November 2022, 58 individuals enrolled in the study with 54 participants (93%) completing 30 days of treatment (26 in the curcumin group and 28 in the placebo group). Of note, 1 individual in the curcumin arm did not experience a qualifying bleeding event and, thus, never initiated treatment and, per protocol, was withdrawn from the study. Participant characteristics did not differ between groups, including length of implant use at study enrollment (placebo, 521±305 days; curcumin, 419±264 days). The study groups did not differ concerning any bleeding-related outcome (mean days without bleeding or spotting: curcumin, 16.7±6.9; placebo, 17.5±4.8; P=.62; mean bleeding-free days: curcumin, 23.4±4.9; placebo, 22.4±4.5; P=.44; bleeding episodes: curcumin, 2.0±0.8; placebo, 2.1±0.8; P=.63). In addition, satisfaction with the implant as contraception and acceptability of bleeding over the study period did not differ by study group (P=.54 and P=.30, respectively). CONCLUSION: Daily use of curcumin did not improve bleeding patterns in users of the etonogestrel contraceptive implant experiencing frequent or prolonged bleeding patterns.

Combined oral contraceptive interference with the ability of ulipristal acetate to delay ovulation: A prospective cohort study.

OBJECTIVE: To determine if a combined oral contraceptive (COC) initiated shortly after ulipristal acetate (UPA) administration interferes with its mechanism of action. STUDY DESIGN: Healthy, reproductive-age women of normal BMI with proven ovulation (serum progesterone >3 ng/ml) were enrolled for three cycles (Cycle 1, UPA only; Cycle 2 washout; Cycle 3 UPA plus COC). During Cycles 1 and 3, subjects were monitored with transvaginal ultrasound and blood sampling for progesterone and LH every other day until a dominant follicle measuring >15 mm was visualized. In both treatment cycles, subjects received UPA (30mg) and were followed daily with similar monitoring for up to 7 days. In Cycle 3 only, subjects initiated a daily COC (0.15 mg levonorgestrel/30 µg ethinyl estradiol) 2 days after UPA. The study had 80% power to detect a 15% difference in the proportion of cycles with at least a 5-day delay in follicle rupture. We assessed follicle rupture as >50% decrease in mean size and adjudicated unclear outcomes with serum hormones. RESULTS: A total of 36 women enrolled and 33 completed all study procedures [age 28.4 years (SD 3.9); BMI 23.4 (SD 2.4)]. Compared to Cycle 1, more subjects demonstrated evidence of follicle rupture in <5 days in Cycle 3 [1/33 (3%) vs. 9/33 (27%), p = .008]. We also included data from 2 subjects who experienced rupture prior to COC dosing in the analysis. CONCLUSION: UPA's effectiveness is significantly reduced by administering COCs 2 days later. IMPLICATIONS: This study demonstrates that UPA's efficacy as an emergency contraceptive is reduced with early exposure to COCs.

Impact of Estrogen Therapy on Lymphocyte Homeostasis and the Response to Seasonal Influenza Vaccine in Post-Menopausal Women.

It is widely recognized that changes in levels of ovarian steroids modulate severity of autoimmune disease and immune function in young adult women. These observations suggest that the loss of ovarian steroids associated with menopause could affect the age-related decline in immune function, known as immune senescence. Therefore, in this study, we determined the impact of menopause and estrogen therapy (ET) on lymphocyte subset frequency as well as the immune response to seasonal influenza vaccine in three different groups: 1) young adult women (regular menstrual cycles, not on hormonal contraception); 2) post-menopausal (at least 2 years) women who are not receiving any form of hormone therapy (HT) and 3) post-menopausal hysterectomized women receiving ET. Although the numbers of circulating CD4 and CD20 B cells were reduced in the post-menopausal group receiving ET, we also detected a better preservation of naïve B cells, decreased CD4 T cell inflammatory cytokine production, and slightly lower circulating levels of the pro-inflammatory cytokine IL-6. Following vaccination, young adult women generated more robust antibody and T cell responses than both post-menopausal groups. Despite similar vaccine responses between the two post-menopausal groups, we observed a direct correlation between plasma 17ß estradiol (E2) levels and fold increase in IgG titers within the ET group. These findings suggest that ET affects immune homeostasis and that higher plasma E2 levels may enhance humoral responses in post-menopausal women.

Effects of switching from oral to transdermal or transvaginal contraception on markers of thrombosis.

BACKGROUND: The study was conducted to determine the impact of switching from oral to transdermal patch or vaginal ring contraception on biomarkers of thrombosis. STUDY DESIGN: Current healthy oral contraceptive (OC) users were randomized to switch to either a contraceptive ring (CR) or patch (CP) and underwent phlebotomy to measure surrogate biomarkers of thrombosis [sex hormone-binding globulin (SHBG), free protein S and activated protein C resistance (APC-r)] before switching, and during the fourth cycle of use of the new method. RESULTS: Of 142 reproductive age women enrolled, 120 sample pairs were available for analysis. SHBG increased significantly from baseline in CP users [mean change (95% CI), +29.9 nM (9.6-50)] but not in CR users [-1.6 (-16.6 to 13.5)]. Protein S decreased significantly from baseline in CP users [mean change -7.1% (-12.1 to -2.1)], but increased significantly in CR users [+5.3% (1.1-9.6)]. The APC-r ratio did not undergo a significant change from baseline in either group [CP +0.06 (-0.06 to 0.18), CR +0.02 (-0.10 to 0.14)]. Compared to CR users, subjects using the CP had significantly higher SHBG [187.5 (167.0-208), 146 (132.6-159.4), p=.012], significantly lower protein S [81.8 (76.8-86.8), 93.6 (89.1-98.1), p=.001] and similar APC-r ratios [2.99 (2.85-3.14), 3.09 (2.96, 3.22), p=.3] at the Cycle 4 visit. CONCLUSION: OC users who switch to the ring exhibit beneficial changes in biomarkers of thrombosis, while those switching to the patch display a shift favoring clot formation.
