A taste alteration-related scale assesses megestrol to improve chemotherapy-induced anorexia.

PURPOSE: We evaluated the efficacy of megestrol in improving chemotherapy-related anorexia by analyzing the related scales of taste alteration. METHODS: We conducted the current study on a group of advanced patients with cancer with two or more chemotherapy cycles. The chemotherapy-induced taste alteration scale (CiTAs) scale helped assess the megestrol effects on basic taste perception, aversive taste changes, unpleasant symptoms, and associated concerns. Furthermore, the Short Nutritional Assessment Questionnaire scale (SNAQ) helped measure the impact of megestrol on malnutrition likelihood in patients experiencing chemotherapy-induced anorexia. The World Health Organization Quality of Life (WHOQOL)-BREF Scale was used to evaluate the quality of life of participants, producing scores related to physical health, psychological well-being, environmental factors, and social relationships. RESULTS: The CiTAs scale assessment indicated that administering megestrol significantly enhanced taste perception among advanced patients with cancer undergoing chemotherapy. Notably, the megestrol group patients showed significantly higher Short Nutritional Assessment Questionnaire (SNAQ) scores than the control group. The megestrol group patients also exhibited higher physiological (PHYS) scores than their control group counterparts. However, this distinction was not statistically significant. The study findings indicate that patients who received megestrol demonstrated significantly higher scores in psychological (PSYCH) and environmental(ENVIR) domains than the control group. Furthermore, megestrol administration was associated with significantly elevated SOCIL and ENVIR levels in patients. CONCLUSION: The proficient efficacy evaluation of megestrol in enhancing appetite, mitigating malnutrition likelihood, and improving the quality of life of chemotherapy-induced anorexic patients can be achieved through taste-related scales.

Comparison of the effect of levonorgestrel-intrauterine system with or without oral megestrol acetate on fertility-preserving treatment in patients with atypical endometrial hyperplasia: A prospective, open-label, randomized controlled phase II study.

OBJECTIVE: To compare the effects of levonorgestrel-intrauterine system (LNG-IUS) with or without oral megestrol acetate (MA) versus MA alone on fertility-preserving treatment in patients with atypical endometrial hyperplasia (AEH). METHODS: This was a single-center phase II study with an open-label, randomized, controlled trial conducted between July 2017 and June 2020 at the Obstetrics and Gynecology Hospital of Fudan University, Shanghai, China. A total of 180 patients (18-45 years) with primary AEH were randomly assigned (1:1:1) to the MA (N = 60), LNG-IUS (N = 60), or MA + LNG-IUS (N = 60) groups, in which the patients received MA (160 mg orally daily), LNG-IUS, or MA + LNG-IUS (MA 160 mg orally daily plus LNG-IUS), respectively. The primary endpoint was complete response (CR) rate at 16 weeks of treatment. The secondary endpoints were CR rate at 32 weeks of treatment, adverse events, and recurrence and pregnancy rates. All analyses were conducted in a modified intention to treat (ITT) population who underwent randomization and in whom treatment was initiated. RESULTS: The Kaplan-Meier estimate of 16-week CR rates (with 95% confidence interval) were 19.2% (9.0-29.4%) in the MA group, 35.0% (22.8-47.2%) in the LNG-IUS group, and 29.4% (17.2-41.6%) in the MA + LNG-IUS groups. Side effects such as weight gain, increased nocturnal urine, night sweat, insomnia and edema face seemed to occur less frequently in LNG-IUS group compared with MA group. No difference was found among groups regarding second endpoints. CONCLUSIONS: LNG-IUS or LNG-IUS plus MA did not show significant therapeutic benefit compared with MA alone. Further studies including sufficient sample-size are needed to validate these findings due to the underpowered design of this trial. FUNDING: This study was supported by the National Key Research and Development Program of China (Grant No 2019YFC1005200 and 2019YFC1005204), Shanghai Medical Centre of Key Programs for Female Reproductive Diseases (Grant No. 2017ZZ010616), Shanghai sailing program (Grant No. 19YF1404200), and Shen Kang clinical project (SHDC22021219).

Objective: Evaluate the efficacy and safety of the use of Megestrol Acetate to treat ACS in patients under palliative care. Methods: Rapid review protocol of Systematic Reviews and Clinical Trials. A literature Search was performed in PUBMED, EMBASE, SCOPUS, BVS, Cochrane Library, Web of Science databases and in clinical trials records, following a predefined strategy. The methodological quality of the selected articles was assessed through AMSTAR-2 (Assessing the Methodological Quality of Systematic Reviews Version 2) tool. Results: the search resulted in 2,370 articles, after the duplicates exclusion. 1003 were analyzed by tittle and abstracts according the inclusion criteria. 16 were selected for full text reading, and only one considered to have high methodological quality. After the analyses of the Randomized Clinical Trials of the excluded Systematic Reviews, one RCT was included. Two additional studies published after the SR of Ruiz-Garcia et al were also included. Conclusion: based on available evidence, the MA promoted a small gain in body weight and a slight appetite improvement, although these results did not imply an enhancement in their quality of life. Moreover, there is a considerable risk of causing thromboembolic disorders

Conservatively treated endometrial intraepithelial neoplasia/cancer: Risk of intrauterine synechiae.

INTRODUCTION: To determine whether progestin type or number of dilation and curettage procedures (D&Cs) were associated with intrauterine synechiae (IS) or pregnancy outcomes in patients conservatively treated for endometrial intraepithelial neoplasia (EIN) or endometrial cancer (EC). MATERIALS AND METHODS: We evaluated patients conservatively treated for EIN or EC from 2000 to 2017 at an academic center. IS were identified hysteroscopically. We calculated proportions for categorical variables and tested associations between D&C number, progestin, and pregnancy outcomes using Pearson chi-squared and Fisher's exact tests. A post-hoc power analysis indicated sufficient power to detect livebirth. RESULTS: We analyzed 54 patients, 15 with EIN (28 %) and 39 with EC (72 %), with a mean age of 34 ± 1.2 years. Progestin treatment types included megestrol acetate (MA) (n = 24), MA with levonorgestrel intrauterine device (LngIUD) (n = 10), MA followed by LngIUD (n = 3), and LngIUD alone (n = 6). Mean number of D&Cs was 3.9 ± 0.9. Overall, 53 subjects underwent hysteroscopy; 10 (19 %) had IS. When D&Cs were grouped into 0-2, 3-4 and ≥5, each increase in D&C group had a 2.9 higher odds of IS (OR: 2.91, p = 0.04, CI: 1.05-10.02). LngIUD was associated with a nonsignificant 46 % decrease in the odds of IS (OR: 0.54, p = 0.66, CI: 0.08-2.87). Twenty-two women attempted pregnancy; 14 women achieved a total of 20 pregnancies and 9 women had total of 15 livebirths (41 % livebirth rate). The number of D&Cs and progestin treatment type were not associated with pregnancy outcomes. DISCUSSION: Among 54 patients conservatively treated for EC/EIN, nearly 20 % developed IS. However, hysteroscopic and/or fertility treatments may improve pregnancy outcomes.

Upper Gastrointestinal Bleeding in a Male Patient Taking Megestrol Acetate and Rivaroxaban: A Case Report.

OBJECTIVE: This report describes the case of a 76-year-old male who developed an upper gastrointestinal bleed shortly after beginning megestrol acetate (MGA) to treat geriatric failure to thrive (GFTT). He was also taking rivaroxaban for stroke prevention because of atrial fibrillation but had a low risk of bleeding. This article aims to provide the reader with an overview of MGA's impact on hemostasis, as well as a review of therapeutics on appetite stimulants and important transitions of care considerations for GFTT.
SETTING: The primary setting was a community teaching hospital in Florida. The patient had many transitions of care, including hospital-to-skilled nursing facility and then a hospital readmission for the primary problem reported here. A skilled nursing facility medication administration record and outpatient community pharmacy were the primary sources of the patient's admission and discharge medication histories.
PRACTICE CONSIDERATIONS: MGA's published labeling supports a prothrombotic mechanism; however, its pharmacology may also confer anticoagulant properties. This may lead to potential drug-drug interactions in patients on concomitant anticoagulant therapy. There is weak evidence supporting appetite stimulants in GFTT, and transitions of care in this population is especially important because of these patients' frequent care continuum contact.
CONCLUSIONS: MGA, a synthetic derivative of endogenous progesterone used to treat GFTT, may exert either prothrombotic or anticoagulant effects, and as such potential for drug interactions with anticoagulants must be considered. Patients taking MGA should be closely monitored for coagulation changes throughout transitions of care.

Megestrol Acetate Induces Declarative Memory Changes and Cortisol Suppression in Healthy Volunteers.

BACKGROUND: The effects of the glucocorticoid and progesterone receptor agonist megestrol on declarative memory, and the ability of phenytoin to block these effects, were assessed. METHODS: Healthy volunteers received each medication combination (placebo and megestrol, phenytoin and megestrol, and placebo and placebo) using a randomized, crossover design. The Rey Auditory Verbal Learning Test assessed declarative memory. RESULTS: Megestrol was associated with a significant reduction in declarative memory (p = 0.0008), which was attenuated by phenytoin, and was associated with significant cortisol suppression compared to placebo (p < 0.001). CONCLUSION: Changes in memory and cortisol suppression were found in healthy volunteers given megestrol.

Clinical Inquiry: Is megestrol acetate safe and effective for malnourished nursing home residents?

No. Megestrol acetate (MA) is neither safe nor effective for stimulating appetite in malnourished nursing home residents. It increases the risk of deep vein thrombosis (strength of recommendation [SOR]: C, 2 retrospective chart reviews), but isn't associated with other new or worsening events or disorders (SOR: B, single randomized controlled trial [RCT]). Over a 25-week period, MA wasn't associated with increased mortality (SOR: B, single RCT). After 44 months, however, MA-treated patients showed decreased median survival (SOR: B, single case-control study). Consistent, meaningful weight gain was not observed with MA treatment (SOR: B, single case-control study, single RCT, 2 retrospective chart reviews, single prospective case-series).

Progestin-associated shift of meningioma mutational landscape.

Background: Meningiomas are the most common primary tumor of the central nervous system. The relationship between meningioma and progestins is frequently mentioned but has not been elucidated. Patients and methods: We identified 40 female patients operated for a meningioma after long-term progestin therapy and performed targeted next generation sequencing to decipher the mutational landscape of hormone-related meningiomas. A published cohort of 530 meningiomas in women was used as a reference population. Results: Compared with the control population of meningiomas in women, progestin-associated meningiomas were more frequently multiple meningiomas [19/40 (48%) versus 25/530 (5%), P < 10-12] and located at the skull base [46/72 (64%) versus 241/481 (50%), P = 0.03]. We found a higher frequency of PIK3CA mutations [14/40 (35%) versus 18/530 (3%), P < 10-8] and TRAF7 mutations [16/40 (40%) versus 140/530 (26%), P < 0.001] and a lower frequency of NF2-related tumors compared with the control population of meningiomas [3/40 (7.5%) versus 169/530 (32%), P < 0.001]. Conclusion: This shift in mutational landscape indicates the vulnerability of certain meningeal cells and mutations to hormone-induced tumorigenesis. While the relationship between PIK3CA mutation frequency and hormone-related cancers such as breast and endometrial cancer is well-known, this hormonally induced mutational shift is a unique feature in molecular oncology.

Metformin for endometrial hyperplasia.

BACKGROUND: Endometrial cancer is one of the most common gynaecological cancers in the world. Rates of endometrial cancer are rising, in part because of rising obesity rates. Endometrial hyperplasia is a precancerous condition in women that can lead to endometrial cancer if left untreated. Endometrial hyperplasia occurs more commonly than endometrial cancer. Progesterone tablets currently used to treat women with endometrial hyperplasia are associated with adverse effects in up to 84% of women. The levonorgestrel intrauterine device (Mirena Coil, Bayer HealthCare Pharmaceuticals, Inc., Whippany, NJ, USA) may improve compliance, but it is invasive, is not acceptable to all women, and is associated with irregular vaginal bleeding in 82% of cases. Therefore, an alternative treatment for women with endometrial hyperplasia is needed. Metformin, a drug that is often used to treat people with diabetes, has been shown in some human studies to reverse endometrial hyperplasia. However, the effectiveness and safety of metformin for treatment of endometrial hyperplasia remain uncertain. OBJECTIVES: To determine the effectiveness and safety of metformin in treating women with endometrial hyperplasia. SEARCH METHODS: We searched the Cochrane Gynaecology and Fertility Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), PubMed, Google Scholar, OpenGrey, Latin American Caribbean Health Sciences Literature (LILACS), and two trials registers from inception to 10 January 2017. We searched the bibliographies of all included studies and reviews on this topic. We also handsearched the conference abstracts of the European Society of Human Reproduction and Embryology (ESHRE) 2015 and the American Society for Reproductive Medicine (ASRM) 2015. SELECTION CRITERIA: We included randomised controlled trials (RCTs) and cross-over trials comparing metformin (used alone or in combination with other medical therapies) versus placebo or no treatment, any conventional medical treatment, or any other active intervention for women with histologically confirmed endometrial hyperplasia of any type. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed studies for eligibility, extracted data from included studies, and assessed the risk of bias of included studies. We resolved disagreements by discussion or by deferment to a third review author. When study details were missing, review authors contacted study authors. The primary outcome of this review was regression of endometrial hyperplasia histology (with or without atypia) towards normal histology. Secondary outcome measures included recurrence of endometrial hyperplasia, progression of endometrial hyperplasia to endometrial cancer, hysterectomy rate, abnormal uterine bleeding, health-related quality of life, and adverse effects during treatment. MAIN RESULTS: We included three RCTs in which a total of 77 women took part. We rated the quality of the evidence as very low for all outcomes owing to very serious risk of bias (associated with poor reporting, attrition, and limitations in study design) and imprecision.We performed a meta-analysis of two trials with 59 participants. When metformin was compared with megestrol acetate in women with endometrial hyperplasia, we found insufficient evidence to determine whether there were differences between groups for the following outcomes: regression of endometrial hyperplasia histology towards normal histology (odds ratio (OR) 3.34, 95% confidence interval (CI) 0.97 to 11.57, two RCTs, n = 59, very low-quality evidence), hysterectomy rates (OR 0.91, 95% CI 0.05 to 15.52, two RCTs, n = 59, very low-quality evidence), and rates of abnormal uterine bleeding (OR 0.91, 95% CI 0.05 to 15.52, two RCTs, n = 44 , very low-quality evidence). We found no data for recurrence of endometrial hyperplasia or health-related quality of life. Both studies (n = 59) provided data on progression of endometrial hyperplasia to endometrial cancer as well as one (n = 16) reporting some adverse effects in the metformin arm, notably nausea, thrombosis, lactic acidosis, abnormal liver and renal function among others.Another trial including 16 participants compared metformin plus megestrol acetate versus megestrol acetate alone in women with endometrial hyperplasia. We found insufficient evidence to determine whether there were differences between groups for the following outcomes: regression of endometrial hyperplasia histology towards normal histology (OR 9.00, 95% CI 0.94 to 86.52, one RCT, n = 16, very low-quality evidence), recurrence of endometrial hyperplasia among women who achieve regression (OR not estimable, no events recorded, one RCT, n = 8, very low-quality evidence), progression of endometrial hyperplasia to endometrial cancer (OR not estimable, no events recorded, one RCT, n = 13, very low-quality evidence), or hysterectomy rates (OR 0.29, 95% CI 0.01 to 8.37, one RCT, n = 16, very low-quality evidence). Investigators provided no data on abnormal uterine bleeding or health-related quality of life. In terms of adverse effects, three of eight participants (37.5%) in the metformin plus megestrol acetate study arm reported nausea. AUTHORS' CONCLUSIONS: At present, evidence is insufficient to support or refute the use of metformin alone or in combination with standard therapy - specifically, megestrol acetate - versus megestrol acetate alone, for treatment of endometrial hyperplasia. Robustly designed and adequately powered randomised controlled trials yielding long-term outcome data are needed to address this clinical question.

A Phase 2, Randomized, Open-Label Study of Irosustat Versus Megestrol Acetate in Advanced Endometrial Cancer.

OBJECTIVE: Advanced/metastatic or recurrent endometrial cancer has a poor prognosis. Malignant endometrial tissue has high steroid sulphatase (STS) activity. The aim of this study was to evaluate STS as a therapeutic target in patients with endometrial cancer. METHODS: This was a phase 2, multicenter, international, open-label, randomized (1:1), 2-arm study of the STS inhibitor oral irosustat 40 mg/d versus oral megestrol acetate 160 mg/d in women with advanced/metastatic or recurrent estrogen receptor-positive endometrial cancer. The primary end point was the proportion of patients without progression or death 6 months after start of treatment. Secondary end points included progression-free survival, time to progression, overall survival, and safety. RESULTS: Seventy-one patients were treated (36 with irosustat, 35 with megestrol acetate). The study was prematurely stopped after futility analysis. Overall, 36.1% and 54.1% of patients receiving irosustat or megestrol acetate had not progressed or died at 6 months, respectively. There were no statistically significant differences between irosustat and megestrol acetate in response and overall survival rates. Irosustat patients had a median progression-free survival of 16 weeks (90% confidence interval, 9.0-31.4) versus 40 weeks (90% confidence interval, 16.3-64.0) in megestrol acetate patients. Treatment-related adverse events occurred in 20 (55.6%) and 13 (37.1%) patients receiving irosustat or megestrol, respectively. Most adverse events in both groups were grade 1 or 2. CONCLUSIONS: Although irosustat monotherapy did not attain a level of activity sufficient for further development in patients with advanced/recurrent endometrial cancer, this study confirms the activity of hormonal treatment (megestrol acetate) for this indication.

Pharmacy Report: Megestrol Acetate-Induced Adrenal Insufficiency.

A man aged 65 years with metastatic renal cell carcinoma presented for evaluation after a recent fall. A thorough workup of the case was performed and secondary adrenal insufficiency induced by the administration of megestrol acetate was determined to be the cause. Adrenal insufficiency is a serious disorder that is a potential adverse event of megestrol acetate, a medication used to help patients with cancer cachexia increase their appetite and gain weight. This association is not well recognized in clinical practice, so this case highlights the importance of distinguishing possible endocrine complications induced by the long-term administration or sudden discontinuation of megestrol acetate.

Pharmacokinetics of a nanocrystal-containing megestrol acetate formulation: a single-dose, randomized, open-label, 2-part, 2-period crossover study in healthy Korean subjects.

UNLABELLED: OBJECTIVE: The conventional suspension of megestrol acetate contains micronized megestrol acetate, which was recently discovered to have a disadvantage of decreasing bioavailability when taken in a fasting state. Since megestrol acetate is taken to increase appetite, this property becomes a discouraging factor. To improve upon this, an advanced formulation was developed using a nanocrystal drug-delivery system. This study was conducted to compare the safety and pharmacokinetic characteristics between the conventional formulation of megestrol acetate and a generic version of the advanced formulation containing nanocrystals. METHODS: This was a randomized, open-label, 2-period, 2-treatment, crossover, single-dose, 2-part study (part 1 fasting and part 2 fed), conducted in healthy males aged between 20 and 50 years with weight within ± 20% of ideal body weight having no congenital abnormalities or chronic diseases. Different subjects were used in part 1 and part 2, but subjects received a single dose of the reference and test drugs separated by a 14-day washout period. Blood sampling was performed up to 120 hours after dosing using a pre-specified sampling time scheme. Primary pharmacokinetic parameters were C_max and AUC_last of the test and reference formulations of megestrol acetate. Bioequivalence evaluation was based on the standard criterion of 80 - 125% for the 90% confidence interval of geometric mean ratios of test to reference drugs calculated for the pharmacokinetic parameters. To monitor adverse events, both subject interviews and physical examinations were done on a regular time basis. RESULTS: 80 subjects (n = 40 each part) were enrolled, and 79 completed the study. The 90% CIs of the geometric mean ratios of C_max and AUC_last were 4.4625 - 5.6018 and 1.3602 - 1.6418, respectively, for part 1, and 0.9793 - 1.1327 and 0.7721 - 0.8431, respectively, for part 2. No significant difference was discovered in the incidence of adverse events (AEs) when test and reference treated groups were compared. CONCLUSIONS: Our findings suggest that the test formulation of megestrol-acetate-containing nanocrystals is better absorbed and has higher bioavailability compared to the reference formulation in a fasting state. This should allow for a lower dose and better patient compliance.

Use of an ophthalmic formulation of megestrol acetate for the treatment of eosinophilic keratitis in cats.

OBJECTIVE: To evaluate a compounded ophthalmic formulation of 0.5% megestrol acetate to treat eosinophilic keratitis in cats. STUDY DESIGN: Prospective study. ANIMALS STUDIED: Seventeen client owned cats with eosinophilic keratitis in one or both eyes. METHODS: Eosinophilic keratitis was confirmed by cytology. At each visit, fluorescein staining and photography were performed. Cats were initially treated q 8-12 h with 0.5% megestrol acetate in an aqueous base. Serum glucose was measured at the first or second reexamination. RESULTS: Fifteen of 17 (88%) cats had a positive response to treatment, with 6 of 17 (35%) having complete resolution at the first reexamination (2-4 weeks). Two of 17 (12%) cats did not respond to treatment. Most cats required a treatment frequency of once daily to once weekly to maintain remission of disease. No ocular irritation or systemic side effects were noted in any cat. CONCLUSIONS AND CLINICAL RELEVANCE: The use of an ophthalmic formulation of 0.5% megestrol acetate is a viable option for treating feline eosinophilic keratitis.

The Efficacy and Safety of Megestrol Acetate in Protein-Energy Wasting due to Chronic Kidney Disease: A Systematic Review.

OBJECTIVE: To assess the efficacy and safety of oral megestrol acetate (MA) in the management of protein-energy wasting in patients with chronic kidney disease (CKD). DESIGN: A systematic review of English published literature from 1970 until April 1, 2014. SUBJECTS: All adult patients with CKD including both dialysis and non-dialysis-dependent. INTERVENTION: Oral MA. MAIN OUTCOME MEASURE: Efficacy outcomes included changes in body weight, serum albumin, and appetite. Safety outcomes examined included adverse events (AEs) and deaths. RESULTS: A total of 9 studies met the inclusion criteria. No data on MA in non-dialysis CKD patients were available. Statistically significant increases in body weight (range 1.5-5 kg) were reported in 6 trials. Statistically significant increases in albumin (range of 0.22 g/dL-0.52 g/dL) were observed in 5 trials. Improved appetite was observed in 7 trials. All trials were limited by small sample sizes (range 9-32 subjects), short duration (range 8-24 weeks), a high degree of bias, and absence of clinical outcomes such as quality of life or hospitalizations. Forty-seven AEs were reported and included overhydration/excessive fluid gain, diarrhea, hyperglycemia, excessive weight gain, suppressed cortisol levels, thrombophlebitis, nausea/vomiting, confusion/hallucinations, vaginal bleeding, headache/dizziness, and elevated lactate dehydrogenase. There were 26 discontinuations due to death. CONCLUSION: The current evidence for treatment with MA in patients receiving dialysis is sparse with few high-quality trials. The safety of using MA beyond 24 weeks is unknown, and use of MA is associated with significant AEs. At this time, oral MA should be used with significant caution, and only when other treatment options are unavailable.

Using megestrol acetate to ameliorate protein-energy wasting in chronic kidney disease.

BACKGROUND: Various populations are affected by chronic kidney disease (CKD), and a low dose appetite stimulant megestrol acetate (MA) is sometimes recommended in patients with CKD to ameliorate protein-energy wasting (PEW). Patients with CKD are at greater risk of developing PEW since the progression of their disease can cause decreased nutrient intake, catabolic effects, systemic inflammation and metabolic changes. Providers can detect PEW in CKD by identifying low serum levels ≤3.8 g/dl of albumin, <30 mg/dl of transthyretin, or <100 mg/dl of cholesterol. Other characteristics include BMI <22 kg/m(2) (for ≤65 years), unintentional weight loss of ≥5% in three months or ≥10% in six months, body fat percentage <10%, with muscle wasting of a reduction of ≥5% in three months or ≥10% in six months of muscle mass. METHOD: A review of research was completed and data collected from small population-based retrospective studies to determine the effect of MA. RESULTS: Clinical trials demonstrated the effectiveness of MA by showing increases in BMI up to 9%, albumin levels up to 1.1 g/dl, with reported protein and energy intake increases from 27% to 42%. There are potential adverse effects of using MA in CKD. CONCLUSION: After reviewing the available literature, the benefits of using MA should be evaluated against the potential side effects. For further examination of MA's potential benefits, long-term, prospective, large clinical trials should be carried out.
