Treatment of Anemia of Chronic Disease with True Iron Deficiency in Pregnancy
Objective.We assess and compare the efficacy of anemia treatment in pregnant women with anemia of chronic disease with true iron deficiency and in women with iron deficiency anemia.Study Design.Fifty patients with moderate anemia (hemoglobin 8.0–9.9 g/dl) and iron deficiency (ferritin < 15 μg/l) were treated in the Anemia Clinic at the Department of Obstetrics.Results.All patients showed stimulation of erythropoiesis as evidenced by an increase in reticulocyte count at day eight of therapy and showed an increase in hemoglobin and hematocrit at the end of therapy (). The target hemoglobin (≥10.5 g/dl) was achieved in 45/50 women (90%). 12 patients showed anemia of chronic disease with true iron deficiency (12/50; 24%). Seven women (7/12; 59%) with anemia of chronic disease and iron deficiency responded well to anemia treatment. 50% of women with anemia of chronic disease and iron deficiency (3/6) responded well to intravenous iron, and 67% (4/6) responded well to the combination of intravenous iron and recombinant human erythropoietin.Conclusion.Because of frequent true iron deficiency in pregnant women with anemia of chronic disease, anemia of chronic disease in pregnancy is often falsely diagnosed as iron deficiency anemia.- 4 December 2017

Long-Term Efficacy of Postpartum Intravenous Iron Therapy
Background. The potential benefits of administering a dose of intravenous iron in patients with moderate postpartum anaemia rather than oral iron alone remains unproven.Aims.To determine whether a single injection of intravenous iron followed by a 6-week course of oral iron is as effective over 6 months in restoring normal haemoglobin levels and replenishing iron stores in women with moderate postpartum anaemia as a course of oral iron alone in women with mild postpartum anaemia.Materials and Methods. Retrospective two-arm cohort study in women with mild postpartum anaemia (haemoglobin 9.6–10.5 g/dL) prescribed iron daily for 6 weeks () and women with moderate postpartum anaemia (haemoglobin 8.5–9.5 g/dL), given a single 500 mg injection of intravenous iron followed by iron daily for 6 weeks (). Haemoglobin and ferritin were measured 6 months postpartum.Results. Haemoglobin returned to similar mean levels in both groups. Ferritin levels were statistically significantly higher in the intravenous + oral group ( μg/L versus μg/L).Conclusions.Despite lower baseline haemoglobin, intravenous iron carboxymaltose was superior to oral iron alone in replenishing iron stores in moderate postpartum anaemia and may prove similarly beneficial in mild postpartum anaemia.- 6 November 2014

Manual Removal of the Placenta after Vaginal Delivery: An Unsolved Problem in Obstetrics
The third stage of labor is associated with considerable maternal morbidity and mortality. The major complication is postpartum hemorrhage (PPH), which is the leading cause of maternal morbidity and mortality worldwide. Whereas in the event of PPH due to atony of the uterus there exist numerous treatment guidelines; for the management of retained placenta the general consensus is more difficult to establish. Active management of the third stage of labour is generally accepted as standard of care as already its duration is contributing to the risk of PPH. Despite scant evidence it is commonly advised that if the placenta has not been expelled 30 minutes after delivery, manual removal of the placenta should be carried out under anaesthesia. Pathologic adhesion of the placenta in the low risk situation usually is diagnosed at the time of delivery; therefore a pre- or intrapartum screening opportunity for placenta accreta would be desirable. But diagnosis of abnormalities of placentation other than placenta previa remains a challenge. Nevertheless the use of ultrasound and doppler sonography might be helpful in the third stage of labor. An improvement might be the implementation of standardized operating procedures for retained placenta which could contribute to a reduction of maternal morbidity.

Characteristics and determinants of restless legs syndrome in pregnancy
Objective: The aim of this cohort study was to prospectively assess frequency, characteristics, and determinants of restless legs syndrome (RLS) in pregnancy and its impact on sleep. Methods: Pregnant women were prospectively studied in each trimester and 8 weeks postpartum. Assessments included interview about RLS symptoms and sleep disturbances; standardized sleep-wake questionnaires including the International Restless Legs Syndrome Scale (IRLSS) and the Pittsburgh Sleep Quality Questionnaire (PSQI); actigraphic recording of periodic limb movements (PLM); and blood tests including levels of hemoglobin, ferritin, and estrogen. Results: RLS was diagnosed in 58 of 501 women (12%). Positive family history was found in 37% of women with RLS; 59% reported onset of RLS symptoms before the 20th week; 45% had an IRLSS >20 and 100% had a PSQI >5. Hemoglobin levels <11 g/dL were found in 20% of both affected and unaffected women in the third trimester. Women with and without RLS had similar hemoglobin, ferritin, and estrogen levels. IRLSS and PLM in sleep dropped by more than 50% postpartum in women with RLS. Conclusion: We found lower prevalence and earlier onset of symptoms compared to previous studies and confirmed significant improvement after delivery. RLS is clinically relevant due to severe impact on sleep quality. Genetic factors and smoking, but not ferritin, anemia, or estrogen levels, seem to play a role in the pathophysiology of RLS in pregnancy.
