leuprolide and Sleep-Initiation-and-Maintenance-Disorders

Low-dose add-back therapy during postoperative GnRH agonist treatment could lower the risk of add-back-induced endometriosis recurrence and reduce treatment dropout compared with a regular dose. However, the effect of low-dose add-back therapy is still unknown. The aim of this study was to determine whether low-dose add-back therapy can also effectively relieve the hypoestrogenic side effects and simultaneously maintain a therapeutic response of GnRH agonist treatment.. This analysis was a prospective cohort study. During postoperative GnRH agonist treatment, a total of 107 women were prescribed add-back therapy [oral combination tablet; estradiol valerate (1 mg) and medroxyprogesterone acetate (2.5 mg)] (Indivina; Orion, Espoo, Finland) for 20 weeks. Patients in the low dose add-back therapy group were prescribed the tablet once a day, and patients in the regular dose group were given the tablet twice a day. Hypoestrogenic side effects, such as hot flashes and insomnia, were recorded. Patients were also questioned regarding their pelvic symptoms and pain to evaluate the possibility of endometriosis recurrence. Lumbar spine (L2-L4) bone mineral density was measured using dual X-ray absorptiometry. The dropout rates in both groups were also evaluated.. The incidence of hypoestrogenic side effects was lower in the low dose group compared with the regular dose group, including hot flashes (19.2% vs. 21.8%, p = 0.741) and insomnia (15.4% vs. 18.2%, p = 0.699), although there were no significant difference between the groups. In addition, a higher number of patients in the regular dose group dropped out of treatment compared to the low dose group (14.5% and 9.6%, respectively, p = 0.435). The patients in both groups had a significant loss of mean bone mineral density during therapy (p < 0.001 and p = 0.018 for the low dose and regular dose groups, respectively).. Low dose add-back therapy could effectively ameliorate hypoestrogenic side effects and simultaneously maintain the therapeutic response of GnRH agonist treatment. The treatment dropout was lower compared with a regular dose. Therefore, low dose add-back therapy can be considered a treatment choice during postoperative GnRH agonist treatment.

GnRH analogues (GnRH-a) are well established in the treatment of endometriosis. However, due to hypooestrogenic effects, treatment is limited to 6 months. The aim of this randomized, double-blind, comparative study was to evaluate whether symptoms and signs of hypooestrogenism, e.g. hot flushes, sweating and sleeplessness, could be avoided by a steroidal add-back regimen, while the beneficial effect of a GnRH-a on endometriosis could be maintained. In group A, 14 patients were treated with 3.75 mg leuprorelin acetate depot per month i.m. in combination with 20 mg ethinyloestradiol plus 0.15 mg desogestrel orally for 3 weeks. In group P, 13 patients received leuprorelin acetate, following the same schedule as in group A, and placebo. Treatment duration was 6 months. At first-look laparoscopy (postoperatively) group A had an r-AFS score of 23.57 and group P of 24.23. After 6 months of treatment with leuprorelin acetate depot r-AFS scores had dropped to 16.14 in group A and to 6.25 in group P at second-look laparoscopy, achieving statistical significance in both groups (p < 0.001). Hypooestrogenic adverse drug reactions (e.g. hot flushes, sweating and sleeplessness) were more frequently reported in group P, whereas the occurrence of headache was comparable in both groups. Dysmenorrhoea was significantly reduced in both groups, whereas dyspareunia was only decreased in group P. Variations in laboratory values were within normal ranges and did not give any concern about drug safety. Loss of bone mineral density caused by the GnRH-a was reduced by the combined oestrogen/progestin add-back therapy. In conclusion, this therapy can lead to a reduction in hypooestrogenic adverse drug reactions and mostly preserves agonist efficacy with the chance of treatment prolongation.

While women report sleep interruption secondary to nighttime hot flashes, the sleep disrupting impact of nocturnal hot flashes (HF) is not well characterized. We utilized a model of induced HF to investigate the relationship of nighttime HF to sleep architecture and sleep-stage transitions.. Twenty-eight healthy, premenopausal volunteers received the depot gonadotropin-releasing hormone agonist (GnRHa) leuprolide to rapidly induce menopause, manifesting with HF. Sleep disruption was measured on 2 polysomnograms conducted before and after 4-5 weeks on leuprolide, when HF had developed.. 165 HF episodes were recorded objectively during 48 sleep studies (mean 3.4 HF/night). After standardizing to sleep-stage time distribution, the majority of HF were recorded during wake (51.0%) and stage N1 (18.8%). Sixty-six percent of HF occurred within 5 minutes of an awakening, with 80% occurring just before or during the awakening. Objective HF were not associated with sleep disruption as measured by increased transitions to wake or N1, but self-reported nocturnal HF correlated with an increase from pre- to post-leuprolide in the rate of transitions to wake (p = 0.01), and to N1 (p = 0.008).. By isolating the effect of HF on sleep in women without the confound of age-related sleep changes associated with natural menopause, this experimental model shows that HF arise most commonly during N1 and wake, typically preceding or occurring simultaneously with wake episodes. Perception of HF, but not objective HF, is linked to increased sleep-stage transitions, suggesting that sleep disruption increases awareness of and memory for nighttime HF events..
