Study Details

Study Description

Brief Summary

The goal of the research proposed in the current application is to first define how much antibody aging renal transplant and dialysis recipients make after they are vaccinated with the pneumonia vaccine and how this compares to similar aged persons with good renal function and healthy young adults. The investigators will study differences in the kind of B cells and markers on the B cells that are known to be important in the response to the pneumonia vaccine in aging renal transplant and aging dialysis recipients compared to similarly aged and young healthy controls. Finally, the investigators will study how safe the pneumonia vaccine is in aging renal transplants. The answers to these questions will help in designing a better vaccine for older people with a renal transplant or on dialysis.

  • Biological: 13 valent conjugated pneumococcal vaccine
  • Other: Peripheral blood sample
Early Phase 1

Detailed Description

Objectives / Specific Aims

Individuals >65 years of age, are the most rapidly growing population amongst those with end stage renal disease (ESRD) and account for more than 18% of renal transplant (RT) recipients.

The incidence of pneumococcal disease is significantly higher in both elderly and those with RT and the combination of these factors is likely additive, if not synergistic, for invasive pneumococcal disease (IPD). It is recommended that both elderly>65 and RT recipients be vaccinated with a regimen that includes both the 13-valent pneumococcal conjugate vaccine (PCV13) and the 23-valent pneumococcal polysaccharide vaccine (PPV23). However, small immunogenicity studies performed in the transplant populations have not shown superiority of a PCV containing regimen. Moreover, the addition of PCV to the pneumococcal vaccine regimen does not improve protective immunity in this population. Studies to date fail to elucidate the possible foundation of the disappointing immune responses to the PCV regimens.

Specific Aim 1. The investigators will define immune responses by measuring serum antibody and functional antibody responses to PPS 14, 19A and 23F following PCV13 vaccination in RT recipients 65-75 years of age and compare these to: RT recipients 35-45 years of age and persons with DM/HTN but normal function 65-75 years of age to dissect out the age and RT components respectively. Healthy persons 35-45 and 65-75 years of age will be studied as age appropriate reference.

Specific Aim 2. The investigators will measure and characterize the antigen-specific B cell subset response following immunization with PCV13 in the RT recipients 65-75 years of age and compare them to each of the groups described in Specific Aim 1 using flow cytometry and fluorescently labeled PPS and monoclonal antibodies. These measures will be correlated with post-immunization functional antibody activity, a surrogate of protection.

Specific Aim 3. The investigators will measure TNFR expression by B cells following immunization with PCV13 in 65-75 year old RT and compare them to each of the groups described in Specific Aim 1. Gene expression, with focus on the B cell activating factor (BAFF) system, will be measured in PPS-specific and non-PPS specific B cells using single cell genomics and flow cytometry. These measures will be correlated with post-immunization functional antibody activity, a surrogate of protection.

The central hypothesis is that the aging RT population responds poorly to PCV13 vaccination reflecting the combined effects of aging and RT. The investigators postulate that both the number of memory B cells and expression of tumor necrosis factor (TNF) superfamily receptors, which play crucial roles in the response to pneumococcal polysaccharides (PPS), are deficient in the elderly RT population and contribute to poor pneumococcal vaccine responses.

The investigators have developed fluorescently labeled PPS allowing us to study the nature and surface receptors of PPS-specific B cells. The preliminary data demonstrate that RT recipients 1. Respond poorly to pneumococcal immunization as measured by antibody titer and functional antibody activity. 2. RT recipients and healthy elderly have lower absolute number of both IgM and switched memory B cells. 3. The number of PPS-specific IgM and switched memory B cells are significantly lower in RT recipients and 4. TACI and BAFF-R, members of the TNF superfamily receptors, expression is significantly lower in the PPS-specific memory B cells in the RT population versus healthy controls. The overall objective of this proposal is to characterize the immune response and explore possible mechanisms of poor vaccine responsiveness following immunization with PCV in the rapidly growing group of elderly with RT. As the RT population is a heterogeneous group the investigators will study only those in whom the underlying cause of renal failure is diabetes mellitus type 2 (DM2) and/or hypertension (HTN).

Intervention to be studied The intervention to be studied is the immune response to immunization with PCV13 or Prevnar13. This FDA approved vaccine is given as part of the standard of care in Groups 1-4. The experimental part of the protocol in these groups will be blood draws at days 0, 7, 30 and years 1 and 2 in these groups.

In Group 5 two interventions will occur: 1. Immunization with the FDA approved PPV23 or Pneumovax 23 and 2. PCV13 a FDA approved vaccine. In addition, blood samples will be obtained at days 0, 7, 30 year 1 and year2.

Both PPV23 and PCV13 are FDA approved vaccines for use in humans. PCV13 is recommended for all individuals enrolled in Groups 1-4. It is not recommended as routine part of care in Group 5 enrolled individuals however it has never shown to be harmful in this group of individuals.

Study Endpoints The primary endpoint of this study is: quantify the antibody titers in mg/mL and opsonophagocytic antibody titer calculated as serum dilution, number of polysaccharide specific B cells, and absolute number of cells/mL induced by vaccination with PCV13.

Secondary endpoint of the study is to describe differences in gene expression of 56 genes to be determined by single cell PCR and comparing these between groups.

The primary safety endpoint of the study is measured as minimal versus moderate local side effect. Minimal side effect measured as no impairment in activity. Moderate local side effect is a side effect affecting use of the extremity for less than 24 hours.

Inclusion and Exclusion Criteria/ Study Population: as described in inclusion/exclusion section

Diversity: the investigators will attempt to mimic the local renal transplant recipient population consisting of a disproportionately high number of males (>60%) of African-American decent, 50%.

Number of Subjects 275

Study Sites

  1. The MUSC Renal Transplant clinic is located on the 9th floor of the Rutledge Tower

  2. The nephrology clinic at the Ralph H. Johnson VA Medical Center

  3. the P.I.'s laboratory at the Strom Thurmond Building Room 411

Recruitment Methods

  • Potential study participants will be recruited from Ralph H. Johnson Veterans Affair Medical Center and Medical University of South Carolina during the appointment with their treating physician. Flyers will be posted in the waiting room areas of the clinics and attending physicians and clinic nurses will be asked to keep this study in mind and mention availability of these studies to their patients when ordering PCV13 for them.

  • Potential study subjects will be identified by reviewing medical records and by physician's recommendations.

  • Flyers will be used to recruit study subjects as well as broadcast emails for MUSC and VA employees and volunteers.

Consent Process

Informed Consent will be obtained in a private room from all participants at either:
  1. The MUSC Renal Transplant clinic is located on the 9th floor of the Rutledge Tower Or 2.The nephrology clinic at the Ralph H. Johnson VA Medical Center Or 3. the P.I.'s laboratory at the Strom Thurmond Building Room 411

Consent will be sought of competent adults who express interest in the study. The purpose of the study, the study details regarding gathering health information and obtaining blood samples, the potential benefit and risks involved, including risk of blood draw and vaccination, will be explained in detail and in layman terms, as well as the non-standard of care explained to the potential subject (i.e. blood draws for groups 1-4, vaccination protocol and blood draws for group 5).

Study Design / Methods The overall objective of this proposal is to characterize the immune response and explore possible mechanisms of poor vaccine responsiveness following immunization with PCV in the rapidly growing group of elderly with RT. As the RT population is a heterogeneous group the investigators will study only those in whom the underlying cause of renal failure is diabetes mellitus type 2 (DM2) and/or hypertension (HTN). There will be 5 study groups as outlined above.

results obtained in various groups will be compared.

Timing of blood samples Peripheral blood samples will be collected at day 0 (pre-immune), day 7, and day 30 (4 weeks post-PPV23) for groups 1-4 and at days 366, 373 and 396 for group 5. BAFF concentration will be measured at day

The vaccine(s) administered to the participants are FDA approved vaccinations and vaccination protocols. The standard and recommended dose of vaccine will be administered either by a qualified nurse or physician and both vaccines are considered low risk. In groups 1-4 PCV13 will be administered per standard of care and is not part of the experimental protocol. In group 5, both PPV23 and PCV 13 are not routine part of care and are part of the experimental protocol. These vaccines have however been extensively studied in this and other populations and are considered low risk and 70-80% protective against pneumococcal disease.

The risk associated with blood draws is minimal.
