Prevalence and Possible Predictors of Helicobacter Pylori Infection Among Adult Patients with Sickle Cell Disease in Ahmadu Bello University Teaching Hospital North-West, Nigeria.

SCD patients are predisposed to infections due to immune deficiency, abdominal symptoms like dyspepsia and recurrent abdominal pain have been associated with infection.

Hemolytic disease of the fetus and newborn caused by anti-E.

Objective: Maternal allo-antibody production is stimulated when fetal red blood cells are positive for an antigen absent on the mother's red cells. The maternal IgG antibodies produced will pass through the placenta and attack fetal red cells carrying the corresponding antigen. Allo-immune hemolytic disease of the fetus and newborn caused by anti-E rarely occurs.
