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

Abstract 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.

Unraveling Prostaglandin and NLRP3 Inflammasomemediated Pathways of Primary Dysmenorrhea and the Role of Mefenamic Acid and Its Combinations

Painful menstrual cramps during or around the time of the monthly cycle are known as dysmenorrhea. The estimated global prevalence in women of reproductive age ranges from 45% to 95%. It has a significant negative impact on regular activities and productivity at work. However, despite the severe consequences on quality of life, primary dysmenorrhea (PD) is underdiagnosed. Dysmenorrhea has complex pathogenesis. It involves the release of prostaglandins and activation of the nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) inflammasome and also includes the involvement of other mediators such as bradykinin, histamine and acetylcholine. Even though nonsteroidal anti-inflammatory drugs (NSAIDs) remain the most common type of pain medication, the question of which one should be the most preferred is still open to debate. The current review examines the existing evidence for the pathogenesis of PD and makes evidence based and clinical experience based recommendations for the use of mefenamic acid and its combination in the treatment of dysmenorrhea. Mefenamic acid alleviates PD by inhibiting endometrial prostaglandin formation, restoring normal uterine activity, and reducing the inflammatory response by inhibiting the NLRP3 inflammasome and reducing the release of cytokines such as interleukin (IL)-1?. It is also known to have bradykinin antagonist activity. Dicyclomine has a dual action of blocking the muscarinic action of acetylcholine in postganglionic parasympathetic effect or regions and acting directly on uterine smooth muscle by blocking bradykinin and histamine receptors to relieve spasms. According to the experts, mefenamic acid and dicyclomine act synergistically by acting on the different pathways of dysmenorrhea by blocking multifactorial agents attributed to the cause of dysmenorrhea. Hence, the combination of mefenamic acid and dicyclomine should be the preferred treatment option for dysmenorrhea.

NLRP3 Inflammasome in the Pathogenesis of Dysmenorrhea and Role of Mefenamic Acid as its Inhibitor

While the role of prostaglandin as a trigger in dysmenorrhea is well known, not many are aware that inflammation and nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) inflammasome are also implicated in primary dysmenorrhea (PD). Inhibition of NLRP3 inflammasome and inflammation pathways is an important approach to treating dysmenorrhea and also the symptoms of premenstrual syndrome. Mefenamic acid is an effective and selective inhibitor of the NLRP3 inflammasome, which can be considered the most important option for PD treatment owing to its action via various pathways. In this article, the authors have reviewed the role of inflammation and NLRP3 inflammasome in causing PD, how inhibitors of NLRP3 inflammasome can treat dysmenorrhea and the mechanism of action of mefenamic acid as NLRP3 inflammasome inhibitor and its role in PD.

Role of Prostaglandins in Pathogenesis of Dysmenorrhea and Place of Mefenamic Acid and Dicyclomine in its Management

Despite being one of the most common gynecological issues faced by women of reproductive age, dysmenorrhea largely remains an ignored, underdiagnosed and untreated condition. It continues to be a public health issue and has a significant impact on the quality of life of the affected women in terms of inability to lead routine activities, absenteeism from academic activities or work and reduced social activities. Currently, existing evidence correlates and implicates the excessive synthesis of prostaglandins with the menstrual pain. Hence, treatment approaches that can inhibit prostaglandins' production or already formed prostaglandins can provide relief in dysmenorrhea. In this review, the impact of dysmenorrhea on the quality of life of women, the role of prostaglandins in the pathogenesis of dysmenorrhea, and how nonsteroidal anti-inflammatory drugs (NSAIDs) like mefenamic acid can be safe and effective in managing dysmenorrhea are discussed.

Probiotics for woman’s health focus on urogenital infections and reproductive outcomes

Depletion in vaginal Lactobacilli colonization is associated with poor urogenital health and adverse pregnancy outcomes. Probiotic supplements containing lactobacilli, when administered in adequate amounts, increased vaginal and gut colonization of Lactobacilli, reduced the incidence of bacterial vaginosis and other urogenital infections. Probiotic Lactobacilli reduced preterm births and improved fertility rates in women following in vitro fertilization. Probiotics may also improve implantation rate and live-birth rate in women undergoing IVF. The purpose of this review was to critically analyse the available literature for synthesizing evidence on the use of probiotics and its effect on urogenital and reproductive health in women.
