A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to explore the impact of prednisolone, a glucocorticoid, on uterine natural killer (uNK) cells in women who have experienced recurrent miscarriages. Participants will receive an oral dose of 10 mg/day of prednisolone and will undergo endometrial biopsies at an outpatient clinic to assess the treatment's effects. The study seeks to clarify the inconclusive evidence surrounding prednisolone as a potential therapy for recurrent miscarriage and to understand the underlying mechanisms involved.

Why it matters

Potential benefit: If successful, this treatment could improve pregnancy outcomes for women with a history of recurrent miscarriages.

How similar studies have gone: While the evidence for prednisolone treatment in this context is inconclusive, similar studies have explored its effects, indicating a need for further investigation.
