Anemian hoito keisarin jälkeen laskimonsisäisellä verrattuna oraaliseen rautaan ja synnytyksen jälkeiseen masennukseen: monikeskeinen satunnaistettu avoin leimattu kontrolloitu tutkimus

The objectif of the IRON-DEP Study is to assess the efficacy of intravenous (IV) versus oral iron treatment on the prevalence of postpartum depression (PPD) in women with moderate iron deficiency anemia after caesarean delivery.

Yksityiskohtainen kuvaus

PPD is a frequent (10-20% of delivery) and serious condition that has a detrimental impact on both maternal and child health by altering the quality of their interactions. Moreover, it is a significant risk factor for suicide, which is the leading cause of maternal death.

The increased risk of PPD in women with postpartum anemia has been documented. Women who delivered by cesarean are particularly vulnerable to this risk as this mode of delivery is a risk factor for both postpartum anaemia and postpartum depression. Therefore, correcting anemia and preventing PPD in this population represent a major public health priority.

First line treatment recommended for iron deficiency moderate anaemia (8.0g/dL≤ Hb ≤10.0g/dL) is oral iron. However oral iron is associated with very frequent adverse effects, contributing to poor tolerance and compliance of this treatment. Actually, IV iron is indicated in women with non-severe postpartum anaemia with lack of response or intolerance to oral iron treatment. There is growing interest in the use of intravenous iron and several randomized controlled trials demonstrated that IV iron is significantly more efficient than oral iron supplementation to correct moderate postpartum anaemia and increase haemoglobin level. However, none of them compared the efficacy of IV iron versus oral iron on postpartum depression as a primary outcome.

The hypothesis of the IRON-DEP Study is that, among women with moderate postpartum iron deficiency anaemia after caesarean delivery, the prevalence of PPD symptoms at 8 weeks after delivery is lower in women treated with IV iron than in those treated with oral iron.

The IRON-DEP trial is a phase IV national multicenter comparative randomized controlled superiority open-label trial with 2 parallel groups.

Implementation of the study :

  • 24 french maternity units will be participating
  • Women who delivered by cesarean admitted in the postpartum maternity ward, with postpartum anaemia will be screened to check the inclusion and exclusion criteria.
  • The investigator will inform the eligible patient about the protocol and obtain the written consent
  • The randomization will take place during the hospitalization for caesarean delivery and will be stratified on the centre and on the initial severity of post-partum anemia (according to the postpartum hemoglobin level).
  • IV iron will be administered during hospitalization and participants in the oral iron group will start their treatment during their hospitalization for 8 weeks treatment.
  • A follow up visit at 8 weeks postpartum will be planned at the maternity unit for all participants
  • All participants will fill in self-assessment questionnaires (online or paper form) at inclusion, 8 weeks and 6 months postpartum follow up.

Tulosmittaus

Aikaikkuna
Prevalence of PostPartum Depression (PPD) symptoms defined by an Edinburg Postpartum Depression Scale (EPDS) score ≥ 11
Aikaikkuna: 8 weeks postpartum

Edinburg Postpartum Depression Scale (EPDS) wil be measured by a self-assessment questionnaire at 8 weeks.

The primary measure of treatment effect will be based on the 'treatment policy' estimand: the effect will be measured by including all women who participated in the study, according to the initial randomization, regardless of the treatment they actually received or their adherence to the treatment. If the 8-week value is not observed, these participants will be included in the analysis after imputing their missing value.

Secondary measures of treatment effect will be implemented based on the "principal stratum strategy" estimand: the effect will be measured in women according to the treatment they actually received and in those who achieved a compliance rate of over 80%.

The estimands discussed above will be applied to all efficacy-related criteria. For safety-related criteria, only the second estimand (principal stratum strategy) will be considered.
