Pneumococcal vaccine in sickle cell disease: IgG and IgM antibody response

Reviews of Infectious Diseases
D J Barrett, A J Ammann

Abstract

Infection with Streptococcus pneumoniae after immunization with polyvalent pneumococcal polysaccharide vaccine has been reported recently in some patients with sickle cell disease (SCD). Since previous studies have suggested that patients with functional hyposplenia may not be able to produce normal levels of protective antibody and/or to switch from IgM to IgG class of antibody in response to some forms of antigenic challenge, we investigated the ability of patients with SCD to form IgM and IgG antibodies after immunization with pneumococcal polysaccharide. Our results demonstrate that both normal individuals and patients with SCD respond with both IgM and IgG antibodies. The level and predominant class of antibody varied with the serotype of antigen tested. Although statistically significant differences were not found, slightly lower responses, especially to pneumococcal polysaccharide type 6, were noted for patients with SCD. Further investigation of the immunoglobulin class of antibody produced by patients with vaccine failure will be necessary to determine if inadequate IgG or IgM response contributes to the lack of protection for these patients.

Allergy & Infectious Diseases

Allergies result from the hyperreactivity of the immune system to some environmental substance and can be life-threatening. Infectious diseases are caused by organisms including bacteria, viruses, fungi and parasites. They can be transmitted different ways, such as person-to-person. Here is the latest research on allergy and infectious diseases.

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.

Bacterial Pneumonia (ASM)

Bacterial pneumonia is a prevalent and costly infection that is a significant cause of morbidity and mortality in patients of all ages. Here is the latest research.

Antibody Specificity

Antibodies produced by B cells are highly specific for antigen as a result of random gene recombination and somatic hypermutation and affinity maturation. As the main effector of the humoral immune system, antibodies can neutralize foreign cells. Find the latest research on antibody specificity here.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
