Burden of Rhesus isoimmunization and pregnancy outcomes: a cross-sectional study conducted at Kenyatta National Hospital, Kenya

the prevalence of Rh isoimmunization among RhD-negative women at KNH was 4.1%. Isoimmunization was significantly associated with miscarriage, hydrops fetalis, IUFD, low birth weight, poor APGAR scores, and NICU admission. Strengthening routine anti-D prophylaxis and improving documentation of its administration after pregnancy loss or delivery are critical to reducing isoimmunization and related complications.
