Patient's question:
Hello, I am O positive blood type, and my husband is A positive blood type. I am currently 6 months pregnant and had a test for neonatal hemolytic disease at the hospital. The test results are as follows:1. ABO blood type antibodies outside the serum (specificity: none; titer: a slash was made; medium: saline + agglutination test)
2. Determination of IgG anti-A(B) titer: IgG anti-A is 128; IgG anti-B (a slash was made).
Could you please tell me if these test results pose a risk to the fetus, what is the probability of neonatal hemolysis occurring, and whether medication is needed for prevention? How can it be prevented? Thank you very much.
Doctor's answer:
Analysis of the condition: It is a major killer of newborn health, typically referring to a group of diseases where maternal antibodies enter the newborn's bloodstream due to blood type incompatibility between mother and child, subsequently destroying the newborn's red blood cells and leading to hemolytic anemia. Clinically, it primarily manifests as jaundice of the skin, with severe cases showing obvious edema and anemia at birth.Advice: Avoiding unnecessary blood transfusions can reduce the incidence of this condition. In mild cases, supplementing with glucose without special treatment can lead to a quick recovery. In severe cases, timely treatment after birth can also result in rapid improvement, with the child growing up to be indistinguishable from normal children. Early bilirubin encephalopathy may still have the potential for recovery after exchange transfusion, while late-stage cases often have sequelae. In cases of generalized edema, even with active treatment, the chances of success are relatively low.
