Real-world utilization pattern of dydrogesterone in 7287 Indian women with obstetric and gynecological conditions: data from multicentric, retrospective study.

Objective: Despite the literature on dydrogesterone, studies on dydrogesterone utilization patterns are largely lacking in Indian patients. Methods: This was a multi-center, retrospective, observational, cross-sectional, and descriptive study across 817 centers in India. Data of patients who received dydrogesterone in past and provided consent for future use of their medical record for research purpose was were retrieved and analyzed. Results: Data of 7287 subjects (aged 29.55±4.84 years) was analyzed. Threatened abortion was the most common indication for which the subjects received dydrogesterone (46.9%) followed by recurrent pregnancy loss. Polycystic ovary syndrome (PCOS), thyroid disorders and anemia were the most common comorbid conditions and prior pregnancy loss, advanced maternal age and obesity were the most common risk factors seen in subjects who received dydrogesterone. Total 27.5% of subjects received a loading dose of dydrogesterone, and majority (64%) received 40 mg as loading dose. 10 mg dose was used as maintenance or regular dose in 81.4% of the subjects. Twice daily (BID) was the most common dosing frequency (66.6%). The most common concomitant medications being taken by the subjects on dydrogesterone included folic acid (45.1%), iron supplements (30.3%) and calcium and vitamin D3 supplements (25.5%). Another progesterone preparation (oral, injection, vaginal, tubal) other than dydrogesterone was used concurrently in 7.8% of subjects. Conclusion: The study helped to identify the patient population that is benefitted by dydrogesterone and the preferred indications, risk factors, comorbid conditions and concomitant medication used in this patient population at real-life scenario.

The Addition of Dydrogesterone after Frozen Embryo Transfer in Hormonal Substituted Cycles with Low Progesterone Levels / Uso adicional de didrogesterona após transferência de blastocisto em ciclos substituídos com valores baixos de progesterona

Abstract Objective To determine whether a rescue strategy using dydrogesterone (DYD) could improve the outcomes of frozen embryo transfer cycles (FET) with low progesterone (P4) levels on the day of a blastocyst transfer. Methods Retrospective cohort study including FET cycles performed between July 2019 and October 2020 following an artificial endometrial preparation cycle using estradiol valerate and micronized vaginal P4 (400 mg twice daily). Whenever the serum P4 value was below 10 ng/mL on the morning of the planned transfer, DYD 10 mg three times a day was added as supplementation. The primary endpoint was ongoing pregnancy beyond 10 weeks. The sample was subdivided into two groups according to serum P4 on the day of FET: low (< 10 ng/mL, with DYD supplementation) or normal (above 10 ng/mL). We performed linear or logistic generalized estimating equations (GEE), as appropriate. Results We analyzed 304 FET cycles from 241 couples, 11.8% (n = 36) of which had serum P4 below 10 ng/mL on the FET day. Baseline clinical data of patients was comparable between the study groups. Overall, 191 cycles (62.8%) had a biochemical pregnancy, of which 131 (44,1%) were ongoing pregnancies, with a 29,8% miscarriage rate. We found no statistically significant differences in the hCG positive (63 vs 64%) or ongoing pregnancy rates (50 vs 43,3%) between those FETs with low or normal serum P4 values, even after multivariable logistic regression modelling. Conclusion Our results indicate that DYD 10 mg three times a day administered in women who perform FET with P4 serum levels < 10 ng/mL, allows this group to have pregnancy rates beyond 12 weeks at least as good as those with serum levels above 10 ng/mL.

Resumo Objetivo Determinar se uma estratégia de resgate usando didrogesterona (DYD) pode melhorar os resultados dos ciclos de transferência de embriões congelados (TEC) com baixos níveis de progesterona (P4) no dia de uma transferência de blastocisto. Métodos Estudo de coorte retrospectivo que incluiu ciclos TEC realizados entre julho de 2019 e outubro de 2020 após um ciclo de preparação endometrial artificial usando valerato de estradiol e P4 vaginal micronizado (400 mg duas vezes ao dia). Sempre que o valor de P4 sérico estava abaixo de 10 ng/mL na manhã da transferência planejada, adicionou-se 10 mg de DYD tri-diário como suplementação. O desfecho primário foi gravidez evolutiva após 10 semanas. A amostra foi subdividida em dois grupos de acordo com o P4 sérico no dia da TEC: baixo (< 10 ng/mL, com suplementação de DYD) ou normal (acima de 10 ng/mL). Realizamos equações de estimativa generalizada linear ou logística (GEE), conforme apropriado. Resultados Analisaram-se 304 ciclos de FET de 241 casais, dos quais 11,8% (n = 36) tinham valores de P4 sérico abaixo de 10 ng/mL no dia da TEC. Os dados clínicos e demográficos dos pacientes eram comparáveis entre os grupos. Globalmente, 191 ciclos (62,8%) tiveram uma gravidez bioquímica, dos quais 131 (44,1%) foram gestações em curso, com uma taxa de aborto espontâneo de 29,8%. Não encontramos diferenças estatisticamente significativas na taxa de gravidez bioquímica (63 vs. 64%) ou nas taxas de gravidez evolutiva (50 vs. 43,3%) entre TEC com valores séricos de P4 baixos ou normais, mesmo após modelação com regressão logística multivariável. Conclusão Nossos resultados indicam que a suplementação com DYD 10 mg três vezes ao dia em mulheres com níveis séricos de P4 abaixo de 10 ng/mL em ciclos de TEC substituídos parecem conseguir resultados pelo menos tão bons como nos ciclos com valores superiores para taxas de gravidez em curso além de 12 semanas.

Oral dydrogesterone in frozen-thawed embryo transfer cycles

SUMMARY OBJECTIVE: The aim of this study was to compare the use of micronized vaginal progesterone and oral dydrogesterone in the endometrial preparation for frozen-thawed embryo transfer. METHODS: This was a randomized, controlled, open, two-armed clinical trial, with women undergoing frozen-thawed embryo transfer along with hormone replacement therapy for endometrial preparation, between September 2019 and February 2021. A total of 73 patients were randomly selected and orally administered 40 mg/day dydrogesterone (dydrogesterone group, n=36) or 800 mg/day micronized vaginal progesterone (micronized vaginal progesterone group, n=37), after endometrial preparation with transdermal estradiol. The main outcome was a viable ongoing pregnancy with 12 weeks of gestation as evaluated by ultrasound. RESULTS: The reproductive outcomes in frozen-thawed embryo transfer cycles were similar, with pregnancy rates in the dydrogesterone and micronized vaginal progesterone treatment groups being, respectively, 33.3 and 32.4% at 12 weeks pregnancy (confidence interval= -22.4-20.6, p=0.196). CONCLUSIONS: The use of oral dydrogesterone may be a more patient-friendly approach to endometrial preparation in frozen-thawed embryo transfer cycles, avoiding undesirable side effects and discomfort resulting from vaginal administration, while also providing similar reproductive results.

El defecto inherente del endometrio causa fallo de implantación en Técnica de Reproducción Asistida / Inherent defect of the endometrium causes implantation failure in Assisted Reproductive Technique

Introduction. Implantation failure appears to be a significant factor in Assisted reproductive technique (ART) procedures. Even a mature endometrium may be non-receptive, preventing implantation or rejection of implanted embryo in early months of pregnancy, resulting in miscarriage or unexplained infertility with or without other associated factors. Objective. To investigate causes of failed implantation inspite of uneventful Grade I embryo transfer in ART procedure Material and Method. 90 women aged range between 25-40 yr old who visited Department of Reproductive Medicine at Calcutta Fertility Mission, over a period of 24 months(January 2017 to December 2019) , satisfying the inclusion criteria, were enrolled in this observational study. Endometrial aspirate histopathology was done along with ∞5ß3 integrin expression. They were treated with natural micronized progesterone (NMP) or oral dydrogesterone and results of endometrial changes were statistically analyzed. Results. 28.89% and 31.11% of women were seen to have mid-secretory changes of the endometrium after being treated with NMP and dydrogesterone respectively. Integrins were expressed in only 59.26% of women with mid-secretory endometrium and 5.41% of early secretory endometrium, which was statistically significant (p value <0.001). Conclusion. About 70% patients even after treatment with estrogen and progestin did not have adequate response in endometrial maturation. Not all patients with mid-secretory endometrium had integrin positive, when tested. NMP and oral Dydrogesterone have similar effect in endometrial maturation as well as in yielding successful pregnancy in some patients with previously failed In-vitro fertilization embryo transfer (IVF-ET).

Oral dydrogesterone vs. vaginal progesterone capsules for luteal-phase support in women undergoing embryo transfer: a systematic review and meta-analysis.

OBJECTIVE: To identify, appraise, and summarize the evidence from randomized controlled trials (RCTs) comparing oral dydrogesterone to vaginal progesterone capsules for luteal-phase support (LPS) in women offered fresh or frozen embryo transfers following in vitro fertilization. METHODS: Two independent authors screened the literature for papers based on titles and abstracts, then selected the studies, extracted data, and assessed the risk of bias. Dydrogesterone and progesterone were compared based on risk ratios (RR) and the precision of the estimates was assessed through the 95% confidence interval (CI). RESULTS: An electronic search performed on June 7, 2017 retrieved 376 records, nine of which were papers deemed eligible and included in this systematic review and quantitative analysis. Good quality evidence indicates that oral dydrogesterone provided at least similar results than vaginal progesterone capsules on live birth/ongoing pregnancy (RR=1.08, 95%CI=0.92-1.26, I2=29%, 8 RCTs, 3,386 women) and clinical pregnancy rates (RR 1.10, 95% CI 0.95 to 1.27; I2=43%; 9 RCTs; 4,061 women). Additionally, moderate quality evidence suggests there is no relevant difference on miscarriage rates (RR=0.92, 95%CI=0.68-1.26, I2=6%, 8 RCTs, 988 clinical pregnancies; the quality of the evidence was downgraded because of imprecision). CONCLUSIONS: Good quality evidence from RCTs suggest that oral dydrogesterone provides at least similar reproductive outcomes than vaginal progesterone capsules when used for LPS in women undergoing embryo transfers. Dydrogesterone is a reasonable option and the choice of either of the medications should be based on cost and side effects.

Dydrogesterone vs progesterone for luteal-phase support: systematic review and meta-analysis of randomized controlled trials.

OBJECTIVES: To compare the effects of dydrogesterone and progesterone for luteal-phase support (LPS) in women undergoing assisted reproductive techniques (ART). METHODS: We performed a systematic review to identify relevant randomized controlled trials (RCTs) by searching the following electronic databases: Cochrane CENTRAL, PubMed, Scopus, Web of Science, ClinicalTrials.gov, ISRCTN Registry and WHO ICTRP. RESULTS: The last search was performed in October 2015. Eight RCTs were considered eligible and were included in the review and meta-analyses. There was no relevant difference between oral dydrogesterone and vaginal progesterone for LPS with respect to rate of ongoing pregnancy (risk ratio (RR), 1.04 (95% CI, 0.92-1.18); I(2) , 0%; seven RCTs, 3134 women), clinical pregnancy (RR, 1.07 (95% CI, 0.93-1.23); I(2) , 34%; eight RCTs, 3809 women) or miscarriage (RR, 0.77 (95% CI, 0.53-1.10); I(2) , 0%; seven RCTs, 906 clinical pregnancies). Two of the three studies reporting on dissatisfaction of treatment identified lower levels of dissatisfaction among women using oral dydrogesterone than among women using vaginal progesterone (oral dydrogesterone vs vaginal progesterone capsules: 2/79 (2.5%) vs 90/351 (25.6%), respectively; oral dydrogesterone vs vaginal progesterone gel: 19/411 (4.6%) vs 74/411 (18.0%), respectively). The third study showed no difference in dissatisfaction rate (oral dydrogesterone vs vaginal progesterone capsules: 8/96 (8.3%) vs 8/114 (7.0%), respectively). CONCLUSIONS: Oral dydrogesterone seems to be as effective as vaginal progesterone for LPS in ART cycles, and appears to be better tolerated . Copyright © 2015 ISUOG.
