Patients with sickle cell disease have an increased risk of streptococcal pneumonia because (A) macrophages that remove the encapsulated organims are significantly reduced due to a nonfunctioning spleen (B) there is immunologic anergy to the streptococcal capsule which has structural similarity to hemoglobin S (C) the inherent resistance to malaria in sickle cell patients primes the cytotoxic T cells for protozoan, but not bacterial, infections (D) chronic hemolysis in sickle cell disease releases growth factors for the fastidious streptococcal bacteria
