Brief Summary

A non-interventional, observational program to assess the effects of dydrogesterone (Duphaston®) 6-months-administration in patients with confirmed endometriosis in a post-marketing setting in the Russian Federation

Detailed Description

A non-interventional, observational program to assess the effects of oral dydrogesterone therapy in a post-marketing setting whether the effects are related to the regimen of dydrogesterone therapy. In this observational program, assuming that dydrogesterone plays a role in the treatment of endometriosis without suppression of ovulation, the goal is to observe the possible implications of such treatment in terms of treatment regimen and response pattern. In the study will be described effects of Duphaston® 6-months-administration in patients with confirmed endometriosis by assessing pain relief, quality of life, need of self-medication with analgesics, etc.

Primary Outcome Measures
NameTimeMethod
Change in chronic pelvic pain intensity6 months

The changes in chronic pelvic pain intensity assessed by 11-items Numerous Rating Scale (NRS) at the end of observation (Visit 3) versus Baseline (Visit 1) in the prolonged cyclic regime and the continuous regime of Duphaston in patients with endometriosis. The 11-items Numerous Rating Scale (NRS) contains the range from 0 to 10, where 0 represents 'no pain' and 10 represents 'the worst pain'. Patients are asked to point the average pain intensity throughout the last month. The negative change corresponds to better result.

Secondary Outcome Measures
NameTimeMethod
Sexual wellbeing6 months

Description of the change in sexual wellbeing assessed by A Quality Assessment of Patient-Reported Outcome Measures for Sexual Wellbeing (5-points Likert scale) at the end of observation (Visit3) versus Baseline (Visit1). A Quality Assessment of Patient-Reported Outcome Measures for Sexual Wellbeing by 5-points Likert scale proposes patients to rate themselves on a 5-point scale as being 'very satisfied, satisfied, ordinarily, rather not satisfied, not satisfied'. The number (and proportion) of patients in each category will be presented.

Cycles' duration6 months

Description of the cycles' duration during 6-months treatment by Duphaston® in patients with endometriosis

Analgesics using6 months

A number of days per each cycle (1-6) when analgesics were self-administered

Change in chronic pelvic pain intensity3 months, 6 months

Change in Patient-reported severity of chronic pelvic pain assessed by 11-items NRS after 3-months treatment (Visit2) and after 6-months treatment (Visit3) versus Baseline (Visit1) in patients with endometriosis

Change in Quality of Life3 months, 6 months

Changes in Quality of Life assessed by Short Form-20 (SF-20) at the end of observation (Visit3) versus Baseline (Visit1) in patients with endometriosis. The Short Form-20 (Copyright © the RAND Corporation) consists of 20 questions grouped into two parameters: psychological and physical components of health. The indicators of each scale are compiled in such a way that the higher the value of the indicator (from 0 to 100), the better the score on the chosen parameter.

Change in dysmenorrhea3 months, 6 months

Description of the changes in dysmenorrhea assessed by 11-items NRS after 3-months treatment (Visit2) and after 6-months treatment (Visit3) versus Baseline (Visit1) in patients with endometriosis. The 11-items Numerous Rating Scale (NRS) contains the range from 0 to 10, where 0 represents 'No symptoms' and 10 represents 'the Worst trouble'. Patients are asked to point the average intensity of dysmenorrhea symptoms (cyclic pelvic pain, mood disorders, gastro-intestinal symptoms etc.) during the last menses period. The negative change corresponds to better result.
