RESUMEN

BACKGROUND: Altered neurotransmission of γ-aminobutyric acid (GABA) has been implicated in the pathogenesis of depression. Whether SAGE-217, an oral, positive allosteric modulator of GABA type A receptors, is effective and safe for the treatment of major depressive disorder is unknown. METHODS: In this double-blind, phase 2 trial, we enrolled patients with major depression and randomly assigned them in a 1:1 ratio to receive 30 mg of SAGE-217 or placebo once daily. The primary end point was the change from baseline to day 15 in the score on the 17-item Hamilton Depression Rating Scale (HAM-D; scores range from 0 to 52, with higher scores indicating more severe depression). Secondary efficacy end points, which were assessed on days 2 through 8 and on days 15, 21, 28, 35, and 42, included changes from baseline in scores on additional depression and anxiety scales, a reduction from baseline of more than 50% in the HAM-D score, a HAM-D score of 7 or lower, and a Clinical Global Impression of Improvement score of 1 (very much improved) or 2 (much improved) (on a scale of 1 to 7, with a score of 7 indicating that symptoms are very much worse). RESULTS: A total of 89 patients underwent randomization: 45 patients were assigned to the SAGE-217 group, and 44 to the placebo group. The mean baseline HAM-D score was 25.2 in the SAGE-217 group and 25.7 in the placebo group. The least-squares mean (±SE) change in the HAM-D score from baseline to day 15 was -17.4±1.3 points in the SAGE-217 group and -10.3±1.3 points in the placebo group (least-squares mean difference in change, -7.0 points; 95% confidence interval, -10.2 to -3.9; P<0.001). The differences in secondary end points were generally in the same direction as those of the primary end point. There were no serious adverse events. The most common adverse events in the SAGE-217 group were headache, dizziness, nausea, and somnolence. CONCLUSIONS: Administration of SAGE-217 daily for 14 days resulted in a reduction in depressive symptoms at day 15. Adverse events were more common in the SAGE-217 group than in the placebo group. Further trials are needed to determine the durability and safety of SAGE-217 in major depressive disorder and to compare SAGE-217 with available treatments.

RESUMEN

The aim of this work was to compare different chemical substances used in the treatment of ganglions located in the hand and wrist region. Their basic properties and mechanisms of action have been described. Moreover, the risks associated with the use of particular substances have been highlighted and potential complications connected with their administration have been discussed. On the basis of the available literature, the results of ganglion aspiration treatment followed by an injection of a chemical substance into the cyst cavity have been assessed. In the authors' opinion, due to the existing risk of complications associated with this treatment, as well as the relatively high rate of ganglion recurrence, this procedure should only be performed by qualified medical personnel. The authors recommend observation in cases of asymptomatic ganglions of the hand and wrist, and operative treatment in cases in which pain, restriction of limb mobility and weakening of handgrip strength are observed.

RESUMEN

OBJECTIVE: To investigate the efficacy and safety of different dosage regimens of zuranolone in the treatment of patients with major depressive disorder (MDD). METHODS: PubMed, Embase, The Cochrane Library and other databases were searched from inception until July 2019. Randomized controlled trials (RCTs) related to the efficacy and safety of zuranolone in the treatment of MDD were included. The data were extracted independently by 2 investigators and assessed the study quality by the Cochrane risk-of-bias tool. The primary outcome includes the 17-item HAMILTON total score (HAMD-17) and the incidence of adverse events (AEs). RESULTS: Six high-quality RCTs with 1593 patients were finally included in our analysis. Zuranolone group achieve a notable treatment effect at day15 in HAMD-17 compared with placebo group (MD = -2.69, 95 % CI: -4.45 to -0.94, P < 0.05). For safety, no significant differences existed in the proportion of patients with AEs between zuranolone with placebo (RR = 1.25, 95 % CI: 0.99 to 1.58, P = 0.06). CONCLUSION: Zuranolone has a significant efficacy in improving depressive symptoms in the short term and is positively correlated with the dosage administered. However, the efficacy of zuranolone decreased significantly when the time of administration was extended. Zuranolone demonstrated a controllable safety issue. But adverse effects increased as the dose of zuranolone was gradually increased to 50 mg.

RESUMEN

Importance: Postpartum depression (PPD) is one of the most common medical complications during and after pregnancy, negatively affecting both mother and child. Objective: To demonstrate the efficacy and safety of zuranolone, a neuroactive steroid γ-aminobutyric acid receptor-positive allosteric modulator, in PPD. Design, Setting, and Participants: This phase 3, double-blind, randomized, outpatient, placebo-controlled clinical trial was conducted between January 2017 and December 2018 in 27 enrolling US sites. Participant were women aged 18 to 45 years, 6 months or fewer post partum, with PPD (major depressive episode beginning third trimester or ≤4 weeks postdelivery), and baseline 17-item Hamilton Rating Scale for Depression (HAMD-17) score of 26 or higher. Analysis was intention to treat and began December 2018 and ended March 2019. Interventions: Randomization 1:1 to placebo:zuranolone, 30 mg, administered orally each evening for 2 weeks. Main Outcomes and Measures: Primary end point was change from baseline in HAMD-17 score for zuranolone vs placebo at day 15. Secondary end points included changes from baseline in HAMD-17 total score at other time points, HAMD-17 response (≥50% score reduction) and remission (score ≤7) rates, Montgomery-Åsberg Depression Rating Scale score, and Hamilton Rating Scale for Anxiety score. Safety was assessed by adverse events and clinical assessments. Results: Of 153 randomized patients, the efficacy set comprised 150 patients (mean [SD] age, 28.3 [5.4] years), and 148 (98.7%) completed treatment. A total of 76 patients were randomized to placebo, and 77 were randomized to zuranolone, 30 mg. Zuranolone demonstrated significant day 15 HAMD-17 score improvements from baseline vs placebo (-17.8 vs -13.6; difference, -4.2; 95% CI, -6.9 to -1.5; P = .003). Sustained differences in HAMD-17 scores favoring zuranolone were observed from day 3 (difference, -2.7; 95% CI, -5.1 to -0.3; P = .03) through day 45 (difference, -4.1; 95% CI, -6.7 to -1.4; P = .003). Sustained differences at day 15 favoring zuranolone were observed in HAMD-17 response (odds ratio, 2.63; 95% CI, 1.34-5.16; P = .005), HAMD-17 score remission (odds ratio, 2.53; 95% CI, 1.24-5.17; P = .01), change from baseline for Montgomery-Åsberg Depression Rating Scale score (difference, -4.6; 95% CI, -8.3 to -0.8; P = .02), and Hamilton Rating Scale for Anxiety score (difference, -3.9; 95% CI, -6.7 to -1.1; P = .006). One patient per group experienced a serious adverse event (confusional state in the zuranolone group and pancreatitis in the placebo group). One patient in the zuranolone group discontinued because of an adverse event vs none for placebo. Conclusions and Relevance: In this randomized clinical trial, zuranolone improved the core symptoms of depression as measured by HAMD-17 scores in women with PPD and was generally well tolerated, supporting further development of zuranolone in the treatment of PPD. Trial Registration: ClinicalTrials.gov Identifier: NCT02978326.

RESUMEN

OBJECTIVE: This paper reviews the current literature available for the efficacy and safety of allopregnanolone agonists and discusses considerations for their place in therapy. LITERATURE SEARCH: A literature search was conducted utilizing PubMed, clinicaltrials.gov, and the manufacturer's website. DATA SYNTHESIS: One phase II trial and two phase III trials evaluating the efficacy and safety of brexanolone were identified. Brexanolone demonstrated efficacy through significantly reduced Hamilton Depression Rating Scale (HAM-D) scores compared to placebo in the treatment of postpartum depression (PPD). Noted adverse effects were somnolence and dizziness, excessive sedation, and loss of consciousness. One published phase II study and the interim results of two phase III trials and one phase II trial on zuranolone were included in this review. Zuranolone, an oral allopregnanolone agonist, is given as a single, 14-day course. A significant reduction in HAM-D scores was demonstrated in patients with major depressive disorder (MDD) at 15 and 28 days compared to placebo. Interim results for zuranolone in PPD and bipolar disorder (BPD) show promising reductions in HAM-D scores. Adverse effects included sedation, dizziness, and headache. PLACE IN THERAPY: Allopregnanolone agonists seem to have a role in PPD when weighing the quick onset of action and potential risks of untreated PPD. The class of medications is limited by the single course for this indication and may fit as a bridge to maintenance therapy with selective serotonin reuptake inhibitors (SSRIs). Brexanolone, specifically, is hindered by the long infusion time, hospitalization associated with administration, and risk evaluation and mitigation strategy program. Zuranolone may also have a role in MDD or BPD, but more data are needed. CONCLUSION: Allopregnanolone agonists present a novel mechanism of action in the treatment of depressive disorders. Clinical trials and interim results support significant reductions in depression scores for brexanolone in PPD, and for zuranolone in PPD, MDD, and BPD.

RESUMEN

Postpartum depression is one of the most common complications of childbirth. Untreated postpartum depression can have substantial adverse effects on the well-being of the mother and child, negatively impacting child cognitive, behavioral, and emotional development with lasting consequences. There are a number of therapeutic interventions for postpartum depression including pharmacotherapy, psychotherapy, neuromodulation, and hormonal therapy among others, most of which have been adapted from the treatment of major depressive disorder outside of the peripartum period. Current evidence of antidepressant treatment for postpartum depression is limited by the small number of randomized clinical trials, underpowered samples, and the lack of long-term follow-up. The peripartum period is characterized by rapid and significant physiological change in plasma levels of endocrine hormones, peptides, and neuroactive steroids. Evidence supporting the role of neuroactive steroids and γ-aminobutyric acid (GABA) in the pathophysiology of postpartum depression led to the investigation of synthetic neuroactive steroids and their analogs as potential treatment for postpartum depression. Brexanolone, a soluble proprietary intravenous preparation of synthetic allopregnanolone, has been developed. A recent series of open-label and placebo-controlled randomized clinical trials of brexanolone in postpartum depression demonstrated a rapid reduction in depressive symptoms, and has led to the submission for regulatory approval to the US Food and Drug Administration (decision due in March 2019). SAGE-217, an allopregnanolone analog, with oral bioavailability, was recently tested in a randomized, double-blind, placebo-controlled phase III study in severe postpartum depression, with reportedly positive results. Finally, a 3ß-methylated synthetic analog of allopregnanolone, ganaxolone, is being tested in both intravenous and oral forms, in randomized, double-blind, placebo-controlled phase II studies in severe postpartum depression.

RESUMEN

Neuroactive steroids are a large group of substances having effect in the brain and on brain function. The steroids most studied are allopregnanolone (ALLO), tetrahydrodesoxycorticosterone (THDOC), pregnenolone sulfate (PS) dihydroepiandrosteronesulfate (DHEAS), and estradiol (E2). ALLO and THDOC are called gamma-aminobutyric acid (GABA) steroids as they are positive modulators of the GABAA receptor in a similar way as benzodiazepines, barbiturates, and alcohol. GABA steroids not only have similar behavioral effects as benzodiazepines and barbiturates but, possibly, also similar adverse effects as well. This review aims to elucidate the possible role that neuroactive steroids play in the development of mood disorders in women. One of the most clear-cut examples of the interaction between mood, neuroactive steroids, and the GABA system is premenstrual dysphoric disorder (PMDD), which is a cluster of negative mood symptoms occurring during the luteal phase of the menstrual cycle in 2-6% of reproductive women. Furthermore, certain women also experience adverse mood effects during sequential progestin addition to postmenopausal estrogen treatment, which is why the role of neuroactive steroids in postmenopausal women is also addressed in this review.

RESUMEN

PIP: Over a 1-year period, 44 women using either Demulen, Deladroxate or the Lippes loop were studied at the University of Pennsylvania for urinary tract disorders. Monthly catheterized urine specimens were cultured and examined cytologically. Excretory urograms and serum creatinine examinations were performed 1 month prior to and 6 and 12 months after contraceptive initiation. No effect on the urinary tract was observed by X-ray studies. All serum creatinines remained normal. Urine sediments showed cytologic patterns consistent with phase of cycle. Incidence of asymptomatic bacteriuria was 6.8% initially and 11% during the course of study. Only 1 Demulen patient developed asymptomatic tract infection. Urographic abnormalities were found in a certain percentage of women of reproductive age irrespective of contraceptive use. Study results, are confirmed by urograms of family planning clinic patients, indicate that estrogen-progestogen contraceptives appear to have little significant effect on human tract anatomy or infection rate.^ieng

RESUMEN

PIP: A clinical series in a private gynecological practice with 50 patients aged 19-43 years who were seen between January 1966 and July 1968 were given a daily dosage of .5 mg norgestrel and .5 mg ethinyl estradiol for a 21 day course. 7 of the women (14%) were seen for counseling in preparation for marriage, 29 were married and had delivered, and the remaining 14 wished to postpone pregnancy. In 88%, menstrual flow remained unchanged, while 6% reported a heavier flow with the duration of bleeding unchanged. 1 patient claimed her cycle was shortened. Breakthrough bleeding occurred in .3% of cycles. 3 patients complained of spotting. Side effects were minor and usually occurred in the first 2 cycles, but over 504 cycles the women remained well and made no complaints. 5 patients indicated a weight gain, and 12 complained of gastric intolerance. 56% continued oral contraceptive use, 6 discontinued for a planned pregnancy, and 8 were transferred to another contraceptive measure because of continued weight gain (4), gastric intolerance (1), shortened cycle (1), and wish to rest from oral contraceptives (2).^ieng
