Rhesus (Rh) negative mothers can develop Rh antibodies if they have an Rh-positive newborn, causing haemolytic disease of the newborn (HDN) in subsequent pregnancies. lecture Rh-ISOIMMUNIZATION DR.SURENDRA NATH BERA DR.

The Rh factor (ie, Rhesus factor) is a red blood cell surface antigen that was named after the monkeys in which it was first discovered. RHESUS ISOIMMUNIZATION IMMUNIZATION.ppt - RHESUS ISOIMMUNIZATION IMMUNIZATION DR WANYORO INTRODUCTION \u2022 \u2022 \u2022 \u2022 \u2022 Definition Iso-immunization On the mechanism of tolerance to the Rh D antigen mediated by passive anti-D (Rh D prophylaxis).

Administering anti-D immunoglobulin to Rhnegative women within 72 hours of giving birth to an Rh-positive baby is an effective way of preventing RhD alloimmunization and HDN (1). Studies on Rh prophylaxis. However, Rhesus alloimmunization … Isoimmunization is the process of immunizing a species with antigen derived from the same subject. It is a condition that may occur during pregnancy when there is an incompatibility between your blood type and your baby’s blood type. Draft scope for the appraisal of Rh-D negative women routine antenatal anti-D prophylaxis (review). Issue Date: March 2007 Page 4 of 5 . Presentation Summary : Isoimmunization: is the process of immunizing a species with antigen derived from the same subject. Transfusion 1971; 11:333. Isoimmunization is also referred to as maternal sensitization. Isoimmunization in pregnancy primarily involves the Rh system of red-blood-cell antigens, but it can also involve other, irregular antigens. 1.4 It is recommended that high-quality information, validated and produced at the national level, is made available to RhD-negative women and the relevant healthcare professionals. Definition Isoimmunization, or maternal blood group immunization, is the development of circulating antibodies by the mother directed against an antigen of fetal origin. Rh incompatibility, also known as Rh disease, is a condition that occurs when a woman with Rh-negative blood type is exposed to Rh-positive blood cells, leading to the development of Rh antibodies. Alloimmunization, often called Rh-isoimmunization or Rh incompatibility was first described in Rh negative women with an Rh-positive fetus, but it can occur with many other blood type incompatibilities. Rh isoimmunization 1. 3

Download (PPT) Currently, it appears that sonographic findings other than hydrops are not reliable in distinguishing between mild and severe hemolytic disease or in predicting if fetal transfusion will be necessary. • Rh isoimmunization is the primary cause of hemolytic disease of the newborn, although other “irregular” antigens can also be causative.
