Abstract. Context Continuous oral contraception may better suppress the ovary and endometrium, lending itself to the treatment of other medical conditions. Objective Our objective was to determine the effects of continuous vs. Design This was a randomized double blind trial. Setting This trial was performed at an academic medical center in Pennsylvania.

Context Continuous oral contraception may better suppress the ovary and endometrium, lending itself to the treatment of other medical conditions. In physics, the fundamental interactions, also known as fundamental forces, are the interactions that do not appear to be reducible to more basic interactions. Intervention Cyclical oral contraception 2. Main Outcome Measures The primary outcome was vaginal bleeding, and secondary outcomes included hormonal, pelvic ultrasound, quality of life, and safety measures. Results There was no statistically significant difference in the number of total bleeding days between groups, but moderateheavy bleeding was significantly greater with the cyclical regimen mean 1. P 0. 0. 05, with both groups decreasing over time. Endogenous serum and urinary estrogens measured over six cycles were significantly lower P 0. Women in the continuous group also had a smaller ovarian volume and lead follicle size over the course of the trial by serial ultrasound examinations. The Moos Menstrual Distress Questionnaire showed that women on continuous therapy had less associated menstrual pain P 0. P 0. 0. 4 during the premenstrual period. Conclusions Continuous oral contraception does not result in a reduction of bleeding days over a 1. These effects are associated with improved patient symptomatology. The cyclical administration of oral contraception with a pill free interval sprang from the dogma of its developers 1. Dogma dictated a 2. U. S. states and countries, and proscribed by multiple religious authorities, that this medication was a natural menstrual cycle regulator 2. This pill free interval has been associated with increased and even rebound ovarian activity 3,4, which may predispose to user and method contraceptive failure failure to reinitiate the pill andor inadequate suppression of the reawakened hypothalamic pituitary axis after the pill free interval, although pregnancy rates have been similar in randomized trials comparing continuous and cyclical methods 5. Breakthrough bleeding defined as unpredictable bleeding during hormonal contraception has been linked to decreased quality of life and satisfaction with treatment. Continuous administration of the oral contraceptive pill OCP or extended cycles beyond the traditional 2. Because ovarian sex steroids or their fluctuation are implicated in the pathophysiology of many medical conditions, the OCP is also used for a number of noncontraceptive indications, including the treatment of acne 6, hirsutism 7, premenstrual syndrome 8, endometriosis 9, dysmenorrhea 1. Increased efficacy of a continuous regimen may improve care for these disorders. However, there are few adequately designed and blinded trials to establish the risk benefit ratio of continuous vs. We conducted this study to test the hypothesis that a low dose OCP given continuously provides fewer bleeding days, greater ovarian and endometrial suppression, and improved quality of life compared with a traditional cyclical OCP. Subjects and Methods. Design and setting. We conducted a 1. Pennsylvania State College of Medicine in Hershey, Pennsylvania. Participants. The Investigational Review Board at the M. S. Hershey Medical Center approved this study, and all subjects gave written informed consent. We studied 6. 2 nonsmoking women in good health, with normal menstrual cycles 2. We excluded women with a contraindication to OCP use clotting disorders, neoplasia, diabetes, vascular disease, migraines, hyperlipidemia, hypertension, or renalhepatic disease through history or evaluation at the screening visit 1. Fig. 1. Flow chart of subjects in the study. Randomization and interventions. During the screening visit, subjects were examined and completed the Moos Menstrual Distress Questionnaire Form C to obtain baseline measures of quality of life during a spontaneous menstrual cycle with premenstrual, menstrual, and intermenstrual components 1. Each subject was given a bleeding diary at the initial visit to record daily symptoms and bleeding on a subjective ordinal scale 0, no bleeding 1, spotting 2, light bleeding 3, moderate bleeding and 4, heavy bleeding. They began their daily bleeding diaries and urine collections on the first day of their subsequent period and began testing their urine for an LH surge on the seventh day of this untreated cycle to schedule an endometrial biopsy 71. The second visit consisted of a fasting phlebotomy for endocrine, metabolic, safety parameters, transvaginal sonogram, and biopsy. Ovarian size was obtained by measuring the largest plane of the ovary in two perpendicular dimensions and then rotating the vaginal probe 9. The volume of the ovary was calculated using the formula for a prolate ellipsoid length height width 6 1. A two layer, maximum endometrial thickness was measured in the sagittal plane. An endometrial biopsy was performed using a 3 mm suction curette Cooper Surgical, Trumbull, CT 1. Subjects were instructed to collect daily 1. Subjects were randomly assigned at the second visit to a treatment group by a computer generated list using permuted block randomization, in which the block size n 6 was known only to the biostatistician A. R. K. Subjects in the continuous group received 4 wk cycles of 2. Subjects and investigators were blinded by over encapsulating the pills during the fourth week of the cycle and repackaging into 2. Download Divx The Grinch Cartoon more. Pills were begun on the first Sunday after menses. Follow up. Subjects were seen once a cycle during the third week of the 2. We queried for adverse events, performed a pill count and a limited physical examination, collected bleeding diaries and daily urines, dispensed medication, obtained blood for study parameters, and performed a sonogram. All subjects were compliant with their treatment regimens based on the monthly pill count. In addition, we repeated the Moos Questionnaire and endometrial biopsy between pill d 1. OCP therapy for both groups. Subjects were instructed to base the phases of the menstrual cycle on the standard 2. The subjects continued the remainder of their medication and their urines for that cycle, which were collected at the subsequent closeout visit. Outcomes. We assayed serum for sex steroids and gonadotropins each visit, and insulin, glucose, lipid profile, and SHBG at baseline and closeout as previously reported 1. There is no cross reactivity in our serum assay between ethinyl estradiol and the estradiol antibody we use to measure estrogen up to 2. Urinary estrone 3 glucuronide E1. G and pregnanediol 3 glucuronide Pd. G were measured in triplicate using competitive double antibody time resolved fluoroimmunoassays previously described 2. All assays had a method coefficient of variation less than or equal to 1. We did not perform cross reactivity studies of norethindrone acetate and ethinyl estradiol in the urine because most of norethindrone acetate and ethinyl estradiol are excreted in the urine as conjugates. Given the large number of these metabolites and the vagaries as to what all the metabolites are, we realized we would derive far better information by conducting a functional test of cross reactivity than to try to identify and test all the OCP steroid metabolites in vitro. Thus, we compared E1. G and Pd. G levels during the weeks on OCP steroids vs. OCP steroids are relatively short 1. The endocrine profiles clearly reveal that there is undetectable or no cross reactivity of the OCP steroids or their metabolites with the E1. G and pregnanediol 3 glucuronide assays 2. Given the large number of daily urines collected, we selected 1. There were no significant differences in age and body mass index BMI, as well as in baseline sex steroids, lipids, or glycemic parameters between these two groups.
