RESUMEN
INTRODUCTION: In retrospective cohort study of women with unexplained recurrent implantation failure (RIF) and miscarriage (RM), we analyzed the efficacy and safety of intralipid therapy to obtain a live birth. PATIENTS AND METHODS: Women with unexplained RM and/or RIF were included from 2015 to 2018 from three French university hospitals. RESULTS: Among 187 women treated for unexplained recurrent miscarriages and implantation failures, 26 women with median age of 36 years (29-43) received intralipid therapy. Among these 26 women, 10 women with a median age of 33 years (31-40) had a history of spontaneous recurrent miscarriages, with a median of 5 (4-8) previous miscarriages. Live births occurred in 7 (70 %) pregnancies under intralipids and were significantly more frequent than in women with recurrent miscarriages who did not receive intralipid therapy (n = 20, p = 0.02). Age, number of previous miscarriages, and additional therapies did not significantly differ between the two groups. Among the 26 included women, 16 had a history of recurrent implantation failures, with median age of 37 years (29-43) and median 9.5 (3-19) embryo transfers. Clinical pregnancy occurred in 9 (56 %) women receiving intralipids after embryo transfers under intralipids among which 5 (55 %) resulted in a live birth. Comparing successful pregnancies under intralipids with those with fetal loss, no significant differences have been noted. CONCLUSION: Intralipids could be an effective and safe therapy in women with unexplained recurrent miscarriages and infertility.

Approximately 1 to 3% of women have recurrent early miscarriages, defined as ≥3 pregnancy losses before 14 weeks of gestation. The immune deregulation and tolerance rupture could be the origin of these miscarriages in at least 30% of these women. Chronic intervillositis of unknown etiology (CIUE) is a rare placental lesion characterized by intrauterine deaths, growth restriction and high recurrence rate. In cases with recurrent obstetrical adverse events and intrauterine deaths, we previously reported the benefit of hydroxychloroquine combination to prednisone. Even few data raised the potential value of TNF antagonists in early recurrent miscarriages, these cases show its potential value in the setting of recurrent refractory chronic intervillositis and unexplained miscarriages.
