Long-term treatment for endometriosis with dienogest: efficacy, side effects and tolerability.

BACKGROUND: Dienogest (DNG) improves endometriosis-associated pain (EAP) and patients' quality of life; however, the modern cornerstone of the management of endometriosis is the long-term adherence of the patient to medical treatment. OBJECTIVE: To evaluate DNG as a long-term treatment of endometriosis, focusing on patients' compliance and side effects, also correlating with different phenotypes of endometriosis. METHODS: This was a cohort study on a group of patients with endometriosis (n = 114) undergoing long-term treatment with DNG. During the follow up visits (12, 24, and 36 months) patients were interviewed: an assessment of EAP was performed by using a visual analogue scale (VAS) and side effects were evaluated by using a specific questionnaire of 15 items. RESULTS: At 12 months, 81% were continuing the DNG treatment, with a significant reduction of dysmenorrhea, dyspareunia, dyschezia, dysuria and chronic pelvic pain. Of the 19% that discontinued the treatment: 62% was due to spotting, reduced sexual drive, vaginal dryness, and mood disorders. The improvement of EAP was significant for all endometriosis phenotypes, especially in patients with the deep infiltrating type. At 36 months, 73% of patients were continuing the treatment, showing a significant reduction of EAP through the follow up, along with an increase of amenorrhea (from 77% at 12 months to 93% at 36 months). In a subgroup of 18 patients with gastrointestinal disorders, DNG was administered vaginally at the same dosage, showing similar results in terms of efficacy and tolerability. CONCLUSIONS: DNG was an effective long-term treatment for all endometriosis phenotypes, with few side effects that caused the discontinuation of the treatment mainly during the first year. Thus, the course of 1-year treatment is a predictive indicator for long-term treatment adherence.

Evaluation of long-term efficacy and safety of dienogest in patients with chronic cyclic pelvic pain associated with endometriosis.

PURPOSE: To evaluate the efficacy and long-term safety (up to 108 months) of treatment with Dienogest in patients with endometriosis. METHODS: Patients with chronic pelvic pain endometriosis-related were enrolled in this observational study from June 2012 to July 2021. The patients enrolled took Dienogest 2 mg as a single daily administration. Group B of long-term therapy patients (over 15 months) were compared with group A of short-term therapy patients (0-15 months). The effects of the drug on pain variation were assessed using the VAS scale and endometriomas dimensions through ultrasonographic evaluation. Furthermore, has been valuated the appearance of side effects and the effect of the drug on bone metabolism by performing MOC every 24 months in group B. RESULTS: 157 patients were enrolled. The mean size of the major endometrioma progressively decreased from 33.2 mm (29.4-36.9) at T0 to 7 mm (0-15.8) after 108 months of treatment. We found a significant improvement in dysmenorrhea, dyspareunia, dyschezia and non-cyclic pelvic pain. As for the side effects, both groups complained menstrual alterations present in 22.9%. In 27.6% of group B, osteopenia was found. Group B had a higher percentage statistically significant of side effects such as headaches, weight gain and libido reduction compared to group A. 2 CONCLUSION: Long-term therapy with Dienogest has proven effective in controlling the symptoms of the disease and reducing the size of endometriomas, with an increase in the positive effects related to the duration of the intake and in the absence of serious adverse events. Study approved by the "Palermo 2" Ethics Committee on July 2, 2012 No. 16.

[Efficacy and safety of dienogest on ovarian endometrioma].

Objective: To observe the effects and safety of dienogest on the volume and symptoms of ovarian endometrioma (OMA). Methods: The clinical data of 75 patients with OMA who underwent treatment with dienogest (2 mg/day) at the First Affiliated Hospital of Nanjing Medical University from July 1st 2020 to March 31st 2024 were retrospectively analysed, mainly comparing the changes in the volume of OMA and the visual analogue scale (VAS) scores of endometriosis-related pain before and after the treatment, as well as observing the changes in the blood biological indicators, liver and kidney function, coagulation function and changes in breast. Results: The median cyst volumes of the OMA patients at 3, 6 and 12 months of dienogest treatment were 13.21 cm3 (volume reduction rate: 36.00%), 8.33 cm3 (volume reduction rate: 56.00%) and 4.10 cm3 (volume reduction rate: 77.62%), respectively, which were all significantly decreased from the pre-treatment period (all P<0.05). The VAS scores of pain of the OMA patients at 3, 6 and 12 months of dienogest treatment all were 0 mm. Blood cancer antigen 125 (CA125) and cancer antigen 19-9 (CA19-9) levels decreased progressively during treatment (all P<0.05). There were no statistical differences in the coagulation indexes, liver and kidney function indexes of the patients during dienogest treatment compared with those before treatment (all P>0.05). During the follow-up period, there were a few patients with changes in the growth sites or lesion category of the breast nodules, but there were no occurrence of breast cancer or precancerous lesions. Conclusion: Dienogest is effective in reducing OMA volume and alleviating endometriosis-related pain with few adverse effects.

Endometriosis features and dienogest tolerability in women with depression: a case-control study.

OBJECTIVE: Primary aim of this study was to investigate endometriosis characteristics of patients with psychiatric conditions or depression. The secondary aim was to study tolerability of dienogest in this context. METHODS: This observational case-control study included endometriosis data from patients visiting our clinic from 2015-2021. We collected information from patient charts and in phone interviews based on a structured survey. Patients with surgical confirmed endometriosis were included. RESULTS: 344 patients fulfilled the inclusion criteria: n = 255 no psychiatric disorder, n = 119 any psychiatric disorder and n = 70 depression. Patients with depression (EM-D, p=.018; p=.035) or psychiatric condition (EM-P, p=.020; p=.048) suffered more often from dyspareunia and dyschezia. EM-P patients had more often primary dysmenorrhoea with higher pain scores (p=.045). rASRM stage or localisation of lesions did not differ. EM-D and EM-P patients discontinued dienogest treatment more often related to worsening of mood (p= .001, p=.002). CONCLUSION: EM-D or EM-P had a higher prevalence of pain symptoms. This could not be attributed to differences in rASRM stage or location of endometriosis lesions. Strong primary dysmenorrhoea might predispose to develop chronic pain-based psychological symptoms. Therefore, early diagnosis and treatment are relevant. Gynaecologist should be aware of the potential impact of dienogest on mood.

Women with endometriosis and psychiatric disorders especially have more dyschezia and dyspareunia, independent from rASRM stage, depth of infiltration and localisation of endometriosis lesions. Dienogest has an impact on mood especially in already prone patients.Trial registration: trial registration number: NCT04816357. https://clinicaltrials.gov/ct2/show/NCT04816357Date of registration: 22.03.2021, date of enrolment of the first subject: 25.03.2021.

Effects of Nandrolone Decanoate on Skeletal Muscle and Neuromuscular Junction of Sedentary and Exercised Rats.

Background and Objectives: Nandrolone decanoate (ND) is the most widely used among the anabolic androgenic steroids (AAS), synthetic substances derived from testosterone, to improve muscular and health gains associated with exercises. The AAS leads to physical performance enhancement and presents anti-aging properties, but its abuse is associated with several adverse effects. Supraphysiological doses of AAS with or without physical exercise can cause morphological and functional alterations in neuromuscular interactions. This study aims to investigate the effects of ND supraphysiological doses in neuromuscular interactions, focusing on the soleus muscle and its neuromuscular junctions (NMJs) in rats, associated or not with physical exercise. Materials and Methods: Forty male Sprague Dawley rats were divided into four groups: sedentary and exercised groups, with or without ND at the dose of 10 mg/kg/week. The animals were treated for eight weeks, with intramuscular injections, and the soleus muscle was collected for morphological analyses. Results: The supraphysiological doses of ND in the sedentary group caused muscle degeneration, evidenced by splitting fibers, clusters of small fibers, irregular myofibrils, altered sarcomeres, an increase in collagen deposition and in the number of type I muscle fibers (slow-twitch) and central nuclei, as well as a decrease in fibers with peripheral nuclei. On the other hand, in the ND exercise group, there was an increase in the NMJs diameter with scattering of its acetylcholine receptors, although no major morphological changes were found in the skeletal muscle. Thus, the alterations caused by ND in sedentary rats were partially reversed by physical exercise. Conclusions: The supraphysiological ND exposure in the sedentary rats promoted an increase in muscle oxidative pattern and adverse morphological alterations in skeletal muscle, resulting from damage or post-injury regeneration. In the ND-exercised rats, no major morphological changes were found. Thus, the physical exercise partially reversed the alterations caused by ND in sedentary rats.

Long-term treatment of dienogest with symptomatic adenomyosis: retrospective analysis of efficacy and safety in clinical practice.

Objective: To evaluate the efficacy and safety of dienogest (DNG) in women with symptomatic adenomyosis.Methods: Women with symptomatic adenomyosis were included in this retrospective observation study. Group 1 (maximum uterine dimension ≥ 100.0 mm) began DNG after 4 months of GnRH-a administration, Group 2 (maximum uterine dimension < 100.0 mm) received DNG with no prior GnRH-a treatment. All women were assessed for their pain symptoms, uterine size, adverse effects and laboratory hematology at baseline and every 6 months during the treatment.Results: 123 women were enrolled in this study, in Group 1 (71 women) with severe uterine enlargement, the median VAS score was 80 mm prior to GnRH-a administration and 10, 10, 10, 20, and 20 mm, respectively, after 0, 6,12,18, and 24 months of DNG treatment. The mean uterine volume decreased from 262.9 ml to 104.7 ml after GnRH-a therapy, and slowly increased from 104.7 ml to 139.5 ml after 24 month-treatment of DNG. Another 52 women with mild uterine enlargement received DNG without prior GnRH-a administration, median VAS score was 70 mm at baseline and decreased to 20, 20, 10, and 10 mm at 6,12,18, and 24 months. The mean uterine volume slightly decreased from 157.9 ml to 153.3 ml after 24 months of DNG treatment (p > 0.05). All laboratory parameters were in the normal range.Conclusions: DNG is effective and well tolerated as a long-term treatment for symptomatic adenomyosis, and it can be used as maintenance therapy after discontinuation of GnRH-a administration.

Glutamate transporter-1 link astrocytes with heightened aggressive behavior induced by steroid abuse in male CF1 mice.

The astrocytic glutamate transporter GLT-1 performs glutamate uptake thereby mediating NMDAr responses in neurons. Ceftriaxone (CEF) upregulates astrocytic GLT-1 expression/activity, which could counteract excessive glutamate levels and aggressive behavior induced by anabolic synthetic steroids such as nandrolone decanoate (ND). Here, adult male CF-1 mice were allocated to oil (VEH), ND, CEF, and ND/CEF groups. Mice were subcutaneously (s.c.) injected with ND (15 mg/kg) or VEH for 19 days, and received intraperitoneal (i.p.) injections of CEF (200 mg/kg) or saline for 5 days. The ND/CEF group received ND for 19 days plus coadministration of CEF in the last 5 days. On the 19th day, the aggressive phenotypes were evaluated through the resident-intruder test. After 24 h, cerebrospinal fluid was collected to measure glutamate levels, and the pre-frontal cortex was used to assess GLT-1, pGluN2BTyr1472, and pGluN2ATyr1246 by Western blot. Synaptosomes from the left brain hemisphere was used to evaluate mitochondrial function including complex II-succinate dehydrogenase (SDH), Ca2+ handling, membrane potential (ΔÑ°m), and H2O2 production. ND decreased the latency for the first attack and increased the number of attacks by the resident mice against the intruder, mechanistically associated with an increase in glutamate levels and pGluN2BTyr1472 but not pGluN2ATyr1244, and GLT-1 downregulation. The abnormalities in mitochondrial Ca2+ influx, SDH, ΔÑ°m, and H2O2 implies in deficient energy support to the synaptic machinery. The ND/CEF group displayed a decreased aggressive behavior, normalization of glutamate and pGluN2BTyr1472levels, and mitochondrial function at synaptic terminals. In conclusion, the pharmacological modulation of GLT-1 highlights its relevance as an astrocytic target against highly impulsive and aggressive phenotypes.

Evaluating the safety of dienogest in women with adenomyosis: A retrospective analysis.

AIM: Dienogest (DNG) is highly effective for relieving pain caused by endometriosis and adenomyosis. However, women with severe uterine swelling due to adenomyosis who take DNG usually experience metrorrhagia. This study aimed to examine the safety of DNG usage in women with adenomyosis. METHODS: This study included 20 women who were prescribed DNG for adenomyosis in our hospital from January 2016 to December 2016. We retrospectively analyzed women's clinical background characteristics (age, the use of the gonadotropin-releasing hormone agonist as pre-treatment of DNG, the uterus size [major axis, minor axis, maximum thickness in the myometrium, and length of the uterine body] by transvaginal ultrasonography [TVUS], hemoglobin level, and the presence of metrorrhagia during treatment). These variables were compared between the DNG continuation and discontinuation groups using the Mann-Whitney U test. RESULTS: Thirteen women continued DNG, and seven discontinued DNG within 12 months because of metrorrhagia. The uterine size was significantly larger in the discontinuation group than in the continuation group. All uterine measurements had high Spearman rank correlation coefficients (ρ > 0.8, P < 0.05). In six of seven cases in the discontinuation group, adenomyosis was in the anterior wall. Measuring the uterus size and locating adenomyosis by TVUS are simple methods of predicting DNG discontinuation. CONCLUSION: We consider that DNG can be safely administered in women with adenomyosis if the uterine size is <6 cm in the minor axis and the main lesion of adenomyosis is located in the posterior uterine wall.

Anabolic Steroids-Driven Regulation of Porcine Ovarian Putative Stem Cells Favors the Onset of Their Neoplastic Transformation.

Nandrolone (Ndn) and boldenone (Bdn), the synthetic testosterone analogues with strong anabolic effects, despite being recognized as potentially carcinogenic compounds, are commonly abused by athletes and bodybuilders, which includes women, worldwide. This study tested the hypothesis that different doses of Ndn and Bdn can initiate neoplastic transformation of porcine ovarian putative stem cells (poPSCs). Immunomagnetically isolated poPSCs were expanded ex vivo in the presence of Ndn or Bdn, for 7 and 14 days. Results show that pharmacological doses of both Ndn and Bdn, already after 7 days of poPSCs culture, caused a significant increase of selected, stemness-related markers of cancer cells: CD44 and CD133. Notably, Ndn also negatively affected poPSCs growth not only by suppressing their proliferation and mitochondrial respiration but also by inducing apoptosis. This observation shows, for the first time, that chronic exposure to Ndn or Bdn represents a precondition that might enhance risk of poPSCs neoplastic transformation. These studies carried out to accomplish detailed molecular characterization of the ex vivo expanded poPSCs and their potentially cancerous derivatives (PCDs) might be helpful to determine their suitability as nuclear donor cells (NDCs) for further investigations focused on cloning by somatic cell nuclear transfer (SCNT). Such investigations might also be indispensable to estimate the capabilities of nuclear genomes inherited from poPSCs and their PCDs to be epigenetically reprogrammed (dedifferentiated) in cloned pig embryos generated by SCNT. This might open up new possibilities for biomedical research aimed at more comprehensively recognizing genetic and epigenetic mechanisms underlying not only tumorigenesis but also reversal/retardation of pro-tumorigenic intracellular events.

Dienogest reduces endometrioma volume and endometriosis-related pain symptoms.

This study aimed to evaluate the efficacy and adverse effects of dienogest for the treatment of endometriomas. Dienogest (2 mg/day) was administered to patients with endometrioma continuously through the 6-month study period. The patients were prospectively examined on the efficacy and side effects at baseline, at third months, and sixth months of the treatment. Twenty-four out of 30 patients were able to complete the study. The mean volume of the endometrioma decreased significantly from 112.63 ± 161.31 cm³ at baseline to 65.47 ± 95.69 cm³ at a 6-month follow-up (-41%) (p = .005). The VAS score for pelvic pain decreased significantly from 7.50 to 3.00 (p < .001) at the sixth months of treatment. The most common side effects were menstrual irregularities. Laboratory parameters did not change during the study. Dienogest considered being effective for 6 months of use in decreasing the size of endometrioma, reducing endometriosis-associated pain with a favourable safety and tolerability profile.Impact statementWhat is already known on this subject? Laparoscopic excisional surgery for endometrioma is currently the most valid approach in the treatment of endometriomas. However, there are concerns about ovarian reserve damage during surgery.What do the results of this study add? Dienogest considered being effective in decreasing the size of endometrioma, reducing endometriosis-associated pain with a favourable safety and tolerability profile. Long-term use of dienogest in younger patients with endometriomas who are yet to give birth may reduce the possibility of surgery by reducing the size of the endometriomas and may preserve ovarian reserve.What are the implications of these findings for clinical practice and/or further research? Dienogest may reduce the incidence of infectious complications such as pelvic abscess after oocyte retrieval and the surgical procedures in infertile patients with endometrioma.

Modification of endometrioma size during hormone therapy containing dienogest.

The aim of the present study was to evaluate whether hormone therapy containing dienogest is effective in reducing endometrioma size. A retrospective observational study was conducted on 116 women with endometrioma which was evaluated after 6 and 12 months of either no treatment (n = 46), or hormonal therapy containing dienogest (n = 70), without (DNG; n = 34) or with ethinylestradiol (DNG/EE; n = 36). Median (interquartile range) cyst diameter (23.0 mm (21.0 mm)) and volume (9941.2 mm3 (14240.1 mm3)) of untreated were similar to cyst diameter (25.0 mm (14.5 mm) and volume (7587.7 mm3 (13806.2 mm3)) of treated women. After 12 months, endometrioma volume did not vary in untreated women (-34.0 mm3 (55595.0 mm3); -0.77% (93.9%)) while it significantly decreased (-5400 mm3 (15378.7 mm3); -100.0% (27.7%); p<.0001) during hormone therapy. Volume decrease was linearly related to endometrioma volume ([Formula: see text] R2 = 0.899, p<.0001). The effect tended to be greater during DNG alone than DNG/EE (-100.0% (0.0%) vs. -87.9% (47.7%); p<.0004). Cyst disappearance was observed in 4.4% of untreated cases and in 57.1% of cases on hormone therapy (p<.0001) (38.9% with DNG/EE and 76.5% with DNG; p<.03). The early diagnosis and treatment of endometrioma with dienogest-based hormone therapy may be effective in controlling cyst growth and in reducing the need for surgery.

Long-term use of dienogest for the treatment of primary and secondary dysmenorrhea.

AIM: To investigate the safety and efficacy of dienogest (DNG), a progestational 19-norsteroid, administered for 52 weeks in patients with primary and secondary dysmenorrhea. METHODS: A total of 147 patients with dysmenorrhea received 1 mg of DNG orally each day for 52 weeks. The dose could be increased to 2 mg/day at or after Week 12 according to the investigator's determination. The primary safety endpoint was evaluation of adverse events, and the secondary safety endpoint was evaluation of adverse drug reactions. The number of days and severity of genital bleeding were assessed according to records in the patients' diary. Lower abdominal pain and/or low back pain because of dysmenorrhea were assessed according to the dysmenorrhea score. RESULTS: The most frequent adverse drug reaction was irregular uterine bleeding (94.6%). Most subjects completed the 52-week administration. Genital bleeding was more likely to occur in subjects with secondary dysmenorrhea than in those with primary dysmenorrhea, and in subjects with "uterine myoma or adenomyosis" than in those with "endometriosis alone." In any of the categorizations, there tended to be fewer days with genital bleeding as the treatment period increased in length, and most of the genital bleeding cases were mild. The change from baseline in the dysmenorrhea score (mean ± standard deviation [SD]) was -3.7 ± 1.6 at Week 24 of treatment and -4.0 ± 1.3 at Week 52. CONCLUSION: This study showed favorable tolerability of the long-term use of DNG to patients with dysmenorrhea and a sustainable pain relief effect.

Pooled analysis of bleeding profile, efficacy and safety of oral oestradiol valerate/dienogest in women aged 25 and under.

Purpose: To evaluate differences in key outcomes between younger and older women receiving the oral contraceptive oestradiol valerate/dienogest (E2V/DNG).Methods: We conducted a pooled post hoc analysis of primary data from 12 studies of E2V/DNG, stratified by age (≤25 [n = 1309] and >25 [n = 2132] years). Outcomes included safety, efficacy, bleeding profile and hormone-withdrawal-associated symptoms (HWAS). Bleeding and HWAS analyses are also presented for women aged ≤20 years (n = 362). Discontinuations were considered a proxy for patient satisfaction.Results: Results were generally similar for younger and older women. The percentage of women aged ≤25 and >25 years experiencing intracyclic bleeding did not differ between groups (13.4% and 12.8% at cycle 12, respectively), with similar results in women aged ≤20 years (12.7%, cycle 12). Rates of withdrawal bleeding were very similar in women aged ≤25 and >25 years (78.5% and 78.9%, respectively, cycle 12). We also found a similar adjusted Pearl index in the two age groups (0.45 vs 0.57, respectively), similar rates of AEs and HWAS and no difference in discontinuations.Conclusions: Women aged ≤25 and >25 years have a similar experience with an E2V/DNV oral contraceptive, supporting this as an appropriate contraceptive option in younger and older women.

Nandrolone Decanoate: Use, Abuse and Side Effects.

Background and Objectives: Androgens play a significant role in the development of male reproductive organs. The clinical use of synthetic testosterone derivatives, such as nandrolone, is focused on maximizing the anabolic effects and minimizing the androgenic ones. Class II anabolic androgenic steroids (AAS), including nandrolone, are rapidly becoming a widespread group of drugs used both clinically and illicitly. The illicit use of AAS is diffused among adolescent and bodybuilders because of their anabolic proprieties and their capacity to increase tolerance to exercise. This systematic review aims to focus on side effects related to illicit AAS abuse, evaluating the scientific literature in order to underline the most frequent side effects on AAS abusers' bodies. Materials and Methods: A systematic review of the scientific literature was performed using the PubMed database and the keywords "nandrolone decanoate". The inclusion criteria for articles or abstracts were English language and the presence of the following words: "abuse" or "adverse effects". After applying the exclusion and inclusion criteria, from a total of 766 articles, only 148 were considered eligible for the study. Results: The most reported adverse effects (found in more than 5% of the studies) were endocrine effects (18 studies, 42%), such as virilization, gynecomastia, hormonal disorders, dyslipidemia, genital alterations, and infertility; cardiovascular dysfunctions (six studies, 14%) such as vascular damage, coagulation disorders, and arteriosus hypertension; skin disorders (five studies, 12%) such as pricking, acne, and skin spots; psychiatric and mood disorders (four studies, 9%) such as aggressiveness, sleep disorders and anxiety; musculoskeletal disorders (two studies, 5%), excretory disorders (two studies, 5%), and gastrointestinal disorders (two studies, 5%). Conclusions: Based on the result of our study, the most common adverse effects secondary to the abuse of nandrolone decanoate (ND) involve the endocrine, cardiovascular, skin, and psychiatric systems. These data could prove useful to healthcare professionals in both sports and clinical settings.

Efficacy, safety and recurrence of new progestins and selective progesterone receptor modulator for the treatment of endometriosis: a comparison study in mice.

BACKGROUND: Current medical treatments for endometriosis are very limited. Progestin and selective progesterone receptor modulators (SPRM) are developed but their efficacy, safety, mechanism and recurrence in endometriosis are not fully studied. METHODS: In order to compare therapeutic, side effects and therapeutic actions of Esmya, Duphaston and Dienogest in endometriosis. Experimental endometriosis was induced by either intraperitoneal or subcutaneous mouse endometrium transplantation. Lesion size, weight and histology at the end of intervention were compared. Expression of related markers in the endometriotic lesions were examined. Body, uterus and ovary weights, endometrial glands and thickness (ETI), and follicle count were measured. For recurrent study, lesion growth before and after intervention was monitored. RESULTS: After Esmya, Duphaston, Dienogest treatment, lesion size and weight were significantly decreased. Proliferation Pcna expression was significantly decreased in all groups, but proliferation cells were significantly decreased only in Duphaston group. Apoptosis Mapk1 expression and TUNEL-positive cells were significantly increased in Duphaston group. Adhesion Mmp2 and Itgavß3 expression were significantly increased in Esmya group. Plau, Hif1α and Vegfa expression, peritoneal fluid PGE2 levels, and ERα and ERß expression were not affected; while PR expression was significantly lower in all groups. Endometrial gland count in uterus was significantly increased in Dienogest group, ETI was significantly decreased in Duphaston group, and AFC were significantly increased in Esmya group. Upon treatment cessation, lesion growth rebound quickly in Dienogest and Duphaston groups, but slowly in Esmya group. CONCLUSION: Esmya, Duphaston and Dienogest are effective anti-endometriosis drugs targeting proliferation, apoptosis and adhesion. Esmya, Duphaston and Dienogest are all well tolerable, although endometrial glandular hyperplasia was found in Dienogest, endometrial atrophy in Duphaston, follicle accumulation in Esmya.

Symptom-alleviating effect and adverse effect of dienogest in Korean women with endometriosis.

The purpose was to evaluate the effects of dienogest on Korean women with endometriosis. A cross-sectional questionnaire-based survey was conducted for 100 premenopausal women. They had taken or were taking 2 mg of dienogest daily. We assessed the pelvic pain score and quality-of-life (QOL) score before and after taking dienogest as well as the prevalence of short-term (≤12 weeks) and long-term adverse effects (>52 weeks). Patients were classified into three groups: dienogest treatment immediately following surgery (A), dienogest treatment for a recurrence of endometriosis after surgery (B), or dienogest treatment without any surgery (C). In groups A and C, the median pain score (from 5 to 0, p <.001; from 7 to 1.5, p <.001) and median QOL score (from 10 to 5, p = .002; from 7.5 to 6.5, p = .008) were significantly decreased. Irregular bleeding and decreased menstrual flow were more prevalent in patients with dienogest intake of fewer than 12 weeks, while amenorrhea, weight gain, hair loss, and dorsal pain were more prevalent in patients with dienogest treatment of over 52 weeks. Accordingly, proper counseling is necessary when prescribing dienogest.

Long-term dienogest administration in patients with symptomatic adenomyosis.

AIM: Adenomyosis is a common gynecological disorder that causes dysmenorrhea, hypermenorrhea and metrorrhagia. Previously, we reported that 24 weeks of dienogest treatment is highly effective for pain in symptomatic adenomyosis. Up to present, there is no report that describes treatment of adenomyosis with long-term dienogest administration for more than 2 years. In this retrospective cohort study, we investigated the course of long-term dienogest treatment in patients with symptomatic adenomyosis. METHODS: This is a retrospective cohort study. Dienogest was continuously administered at a dose of 2 mg daily for patients with symptomatic adenomyosis. The outcome of long-term administration of dienogest was investigated, and the characteristics of patients were compared between discontinued cases and long-term administration cases. RESULTS: Two patients were excluded from this study because of transfer to another hospital or discontinuation due to infertility treatment. Twelve of 18 patients (66.7%) received dienogest until menopause or for a period of >80 months. Four cases (22.2%) discontinued dienogest treatment because of severe metrorrhagia. In the discontinued cases because of severe metrorrhagia, the pain score for dysmenorrhea and serum CA125 level at baseline significantly elevated, and the hemoglobin level at baseline and the frequency of type 2 adenomyosis significantly decreased, compared to those with long-term use. Moreover, long-term dienogest use did not decrease the serum estradiol level. CONCLUSION: Our report suggests that dienogest is tolerable for long-term use until menopause and can be an alternative treatment option in some patients, especially those with type 2 adenomyosis, to avoid hysterectomy.

Long-term treatment of endometriosis with dienogest: retrospective analysis of efficacy and safety in clinical practice.

PURPOSE: Endometriosis is a debilitating disease with high recurrence rates requiring long-term management. Progestins such as dienogest are used empirically when first symptoms occur and post-surgery to reduce recurrence. This retrospective, practice-based study assessed the efficacy and safety of dienogest in women with endometriosis treated for at least 60 months. METHODS: 37 women (age 39 ± 8 years) with laparoscopically diagnosed endometriosis received dienogest 2 mg orally once daily. Endometriosis-associated pelvic pain (EAPP) was measured on a 0-100 mm visual analog scale at baseline and every 12 months. Laboratory measures of lipid and liver metabolism, hemostatic and hormonal parameters were investigated in a subgroup of 15 women. Adverse events including bleeding disturbances and depressive symptoms were recorded. RESULTS: In 22 women, dienogest was begun after laparoscopy; median EAPP score was 70 mm pre-surgery and 10, 10, 20, 20, and 20 mm, respectively, after 12, 24, 36, 48, and 60 months of dienogest treatment. Another 15 women began dienogest without prior surgery; median EAPP score was 80 mm pretreatment and 20, 20, 30, 30, and 30 mm, respectively, after 12, 24, 36, 48, and 60 months. All laboratory parameters remained within the normal range. Mean serum estradiol was 28 ± 12 pg/ml after 60 months. Seven women experienced spotting episodes and four women presented with phases of depressed mood, which could all be clinically managed. CONCLUSIONS: Long-term (60-month) treatment with dienogest 2 mg once-daily in women with endometriosis effectively reduced EAPP and avoided pain recurrence post-surgery. Dienogest was well tolerated and adverse effects were clinically managed.

Ventricular androgenic-anabolic steroid-related remodeling: an immunohistochemical study.

BACKGROUND: Several fatal cases of bodybuilders, following a myocardial infarction after long exposure to androgenic-anabolic steroids (AAS), are reported. In recent years, evidence has emerged of cases of heart failure related to AAS consumption, with no signs of coronary or aorta atherosclerosis. This study aims to further investigate the pathogenesis of the ventricular AAS-related remodeling performing immunohistochemistry (IHC). METHOD: In order to examine innate immunity activity and myocytes and endothelial cell apoptosis, IHC analyses were performed on heart tissue of two cases of bodybuilders who died after years of supratherapeutic use of metelonone and nandrolone and where no atherosclerosis or thrombosis were found, using the following antibodies: anti-CD68, anti-iNOS, anti-CD163, anti-CD 15, anti-CD8, anti-CD4, anti-HIF1 α, and in situ TUNEL staining. RESULTS: Results confirm the experimental findings of recent research that, in the absence of other pathological factors, if intensive training is combined with AAS abuse, myocytes and endothelial cells undergo apoptotic alterations. The absence of inflammatory reactions and the presence of an increased number of M2 macrophages in the areas of fibrotic remodeling confirm that the fibrotic changes in the heart are apoptosis-related and not necrosis-related. CONCLUSIONS: In conclusion, the study indicates that, in very young subjects with chronic hypoxia-related alterations of the heart, signs of a heart failure in the other organs and a history of AAS abuse, death can be ascribed to progressive heart failure due to the direct apoptotic cardiac and endothelial changes produced by AAS.

Long-term use of dienogest in the treatment of painful symptoms in adenomyosis.

AIM: We aimed to investigate the safety and efficacy of dienogest (DNG), a progestational 19-norsteroid, administered for 52 weeks in patients with symptomatic adenomyosis. METHODS: A total of 130 patients with adenomyosis received 2 mg of DNG orally each day for 52 weeks. In cases of complicated anemia, patients were treated for anemia prior to receiving the medication. Adverse events and adverse drug reactions were evaluated. The patients' pain symptoms (dysmenorrhea and pelvic pain from adenomyosis) were assessed using a pain-scoring tool. This was a verbal rating scale comprising a 0-3-point pain-severity score measuring disability to work, and an analgesics-usage score measuring need for analgesics. RESULTS: The most common adverse drug reactions included metrorrhagia (96.9%) and hot flush (7.7%). However, in most cases, metrorrhagia was tolerable and no clinically significant changes were observed concerning the incidence or severity of reactions during the 52-week treatment period. There were no serious adverse events. Both the pain-severity score and analgesics-usage score decreased after the start of treatment with DNG. The mean ± standard deviation changes from baseline for the pain score were -3.4 ± 1.8 at 24 weeks and -3.8 ± 1.5 at 52 weeks, respectively. CONCLUSION: The long-term use of DNG was well-tolerated and effective in patients with symptomatic adenomyosis.
