1.Cystic endometrial hyperplasia and endometritis in a dog following prolonged treatment of medroxyprogesterone acetate.
Journal of Veterinary Science 2005;6(1):81-82
An 8-year-old female Yorkshire Terrier was presented for investigation of reduced appetite, and occasional vomiting. She has been treated with medroxyprogesterone acetate (MPA) from past 3 year-old age for contraception. Abdominal sonography showed abnormal enlargement of uterus, and ovariohysterectomy was performed. Main gross findings of uterus were enlarged lesions in two areas of the left horn, which had thickened wall and yellowish sticky material in the lumen. Histopathologically, cystic endometrial hyperplasia (CEH) and endometritis were present in the thickened area. In this case, CEH and endometritis may be attributed to prolonged treatment of MPA. It was concluded that further study is needed to clarify the association of MPA treatment with age, its pathogenesis and abnormal uterine changes in dogs.

Objective: To evaluate different methods' efficacy of controlling acute bleeding and managing long-term menstruation in patients with heavy menstrual bleeding (HMB) associated with antithrombotic therapy. Methods: The clinical data of 22 cases with HMB associated with antithrombotic therapy admitted to Peking University People's Hospital from January 2010 to August 2022 were analyzed, aged 39 years old (26-46 years). Changes in menstrual volume, hemoglobin (Hb), and quality of life were collected after control of acute bleeding and long-term menstrual management. Menstrual volume was assessed by pictorial blood assessment chart (PBAC), and quality of life was assessed by menorrhagia multi-attribute scale (MMAS). Results: (1) Treatment of acute bleeding: of the 22 cases with HMB associated with antithrombotic therapy, 16 cases were treated in our hospital and 6 in other hospital for emergency bleeding; of the 16 cases treated in our hospital, 3 underwent emergency intrauterine Foley catheter balloon compression due to severe bleeding (Hb decreased by 20 to 40 g/L within 12 hours). Of the 22 cases with antithrombotic therapy-related HMB, 15 (including 2 cases with severe bleeding) underwent emergency aspiration or endometrial resection, and intraoperative placement of levonorgestrel-releasing intrauterine system (LNG-IUS) followed by a significant reduction in bleeding volume; 3 cases had controlled acute bleeding after rivaroxaban dose reduction and continued observation; 2 cases were given gonadotropin-releasing hormone agonists to control acute bleeding in other hospital, of which 1 case was temporarily treated with periodic blood transfusion, and the other one patient underwent total hysterectomy; and 2 cases had temporary amenorrhea with oral mifepristone after intrauterine balloon compression or oral norethindrone. (2) Long-term menstrual management: of the 22 cases with antithrombotic therapy-related HMB, 15 had LNG-IUS placement and 12 had LNG-IUS placement for 6 months, and menstrual volume was significantly reduced [PBAC scores were 365.0 (272.5-460.0) vs 25.0 (12.5-37.5), respectively; Z=4.593, P<0.001], Hb was significantly increased [91.5 g/L (71.8-108.2 g/L) vs 128.5 g/L (121.2-142.5 g/L); Z=4.695, P<0.001], and quality of life was significantly improved [MMAS scores were 415.0 (327.5-472.5) vs 580.0 (570.0-580.0), respectively; Z=-3.062, P=0.002] before placement compared with 6 months after placement. Three rivaroxaban dose reduction patients' PBAC scores decreased by 20 to 35 but remained >100, and perceived quality of life did not change significantly. Two cases with temporary amenorrhea treated with oral mifepristone felt significantly improved quality of life, and the MMAS scores increased by 220 and 180, respectively. Conclusion: Intrauterine Foley catheter balloon compression, aspiration or endometrial ablation could be used to control acute bleeding in patients with antithrombotic therapy-related HMB, and LNG-IUS for long-term management could reduce menstrual volume, increase hemoglobin, and improve the quality of life of patients.

Various synthetic progestogens that are used as contraceptives have been reported to influence lipid and lipoprotein fractions differently. Depo-medroxyprogesterone acetate (DMPA), a synthetic progestogen, is used by Nepalese women as a contraceptive agent. Our study aims to determine the effects of long-term use of DMPA on lipid metabolism. We performed this study on 60 healthy Nepalese women who had been using DMPA for more than 2 yr and age- and weight-matched control subjects who were not using hormonal contraceptives. Fasting blood samples were collected from the subjects for the estimation of total cholesterol (TC) and triglyceride (TG) levels, and the levels of high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) were estimated using the Friedewald's equation. TC and LDL-C levels in DMPA users were significantly higher than those in non-users. Our study concluded that DMPA use induces lipid metabolism changes that can increase the risk of cardiovascular diseases.
