ABSTRACT
BACKGROUND: The purpose of this study was to investigate the effectiveness of a combination of ethinylestradiol (EE) and 0.02 mg/drospirenone (DRSP) 3 mg in Japanese women with dysmenorrhea and in particular to determine whether or not the presence of specific coexisting organic diseases (eg, endometriosis, uterine fibroids, uterine adenomyosis) has an impact on treatment. METHODS AND RESULTS: Four hundred and ten patients with dysmenorrhea aged 20 years or older (315 without coexisting organic disease, 28 with endometriosis, 37 with uterine fibroids, and 46 with uterine adenomyosis [some patients had multiple coexisting organic diseases]) were enrolled and treated with EE/DRSP in either a 16-week comparator study or a 52-week long-term safety study. Evaluations included changes in total dysmenorrhea score, visual analog scale for dysmenorrhea, severity of symptoms, hormone levels, endometrial thickness, and safety outcomes. In both studies, the total dysmenorrhea score was significantly (P<0.001) decreased from baseline during treatment with EE/DRSP. Time-dependent changes in visual analog score for dysmenorrhea and alleviation of symptoms, such as lower abdominal pain, low back pain (lumbago), headache, and nausea/vomiting, were similar in all patient groups with and without any specific coexisting organic diseases. These improvements with EE/DRSP were observed for both short-term (16 weeks) and long-term (52 weeks) use. These effects were associated with suppressed increases in serum estradiol and progesterone levels and decreased endometrial thickness. The safety profile of EE/DRSP was similar in all patients, irrespective of the presence of coexisting organic diseases. CONCLUSION: EE/DRSP may be prescribed for patients with dysmenorrhea irrespective of the presence of any specific coexisting organic diseases.
ABSTRACT
The biological effects of 20-kDa human GH (20K-hGH), which is produced in the pituitary by alternative splicing of GH mRNA and comprises approximately 6% of all GH in serum, have not been reported. We have investigated the metabolic effects of recombinant 20K-hGH in adult patients with GH deficiency in an exploratory study. Three doses of 20K-hGH (0.006, 0.012, and 0.024 mg/kg.d), were administered for 16 wk to three groups (consisting of 18 or 19 subjects), respectively. The 20K-hGH dose-dependently increased serum IGF-I and IGFBP-3 levels, and the lowest dose (0.006 mg/kg) was enough to normalize both hormones by wk 4. Serum osteocalcin levels and urinary deoxypyridinoline excretion were also dose-dependently increased. There was a significant decrease in body fat mass with an increase of lean body mass at the lowest dose of 0.006 mg/kg.d. Blood glucose and serum insulin were increased significantly at 4 wk only in the high-dose group (0.024 mg/kg). Glucose tolerance was slightly impaired in 26-39% of patients in all treatment groups as judged by oral glucose tolerance tests, but there was no development of overt diabetes. The major adverse event in the 20K-hGH treatment was peripheral edema, similar to the incidence reported for 22K-hGH. The data demonstrated that 20K-hGH had metabolic effects comparable to those of 22K-hGH in humans. The results suggest that 20K-hGH could be used to treat GH-deficient patients, although further studies may be required to investigate the optimum dose and superiority of 20K-hGH over 22K-hGH in a comparative study.
