NCT03802994

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.

Outcome Measures

Primary Outcomes (3)

  • Anti-pneumococcal IgG Antibody (ug/ml) Change

    Measure the opsonic antibody response against streptococcus pneumonia serotypes 14, 19A and 23F at days 0 and 30. Comparing elderly RT recipients versus healthy elderly and elderly with DM/HTN.

    Baseline, 30 days

  • Opsonophagocytic Antibody Titer Serum Dilution Difference Between Healthy Elderly, Elderly With DM/HTN and Elderly With RT.

    Measure the serum opsonophagocytic activity against streptococcus pneumonia serotypes 14, 19A and 23F on days 0 and 30 by opsonophagocytic assay.

    Baseline and 30 days

  • Percentage of Polysaccharide Specific B Cells (% Cells/mL)

    percentage of polysaccharide specific B cells, and percentage of IgM memory B cells/mL in % cells/mL induced by vaccination with PCV13

Study Arms (5)

1.Aging RT

EXPERIMENTAL

Renal transplant recipients between 65-75 years of age, on stable immunosuppression. who previously (\>1 year prior) received the 23 valent pneumococcal polysaccharide vaccine (pneumovax23). Cause or renal failure was either DMII or HTN.

Other: Peripheral blood sample

2.Young RT

ACTIVE COMPARATOR

Renal transplant recipients between 35-45 years of age, on stable immunosuppression. who previously (\>1 year prior) received the 23 valent pneumococcal polysaccharide vaccine (pneumovax23). Cause or renal failure was either DMII or HTN.

Other: Peripheral blood sample

3.Healthy elderly

ACTIVE COMPARATOR

Healthy persons between the ages 65-75 who previously (\>1 year prior) received the 23 valent pneumococcal polysaccharide vaccine (pneumovax23)

Other: Peripheral blood sample

4.Elderly DMII or HTN and normal renal function

ACTIVE COMPARATOR

Persons between the ages 65-75 with DMII or hypertension but normal renal function who previously (\>1 year prior) received the 23 valent pneumococcal polysaccharide vaccine (pneumovax23)

Other: Peripheral blood sample

5.Healthy young

EXPERIMENTAL

Healthy persons between the ages 35-45 who previously (\>1 year prior) received the 23 valent pneumococcal polysaccharide vaccine (pneumovax23) or are willing to receive PPV23 and 1 year later Prevnar 13.

Drug: 23 valent pneumococcal polysaccharide vaccineBiological: 13 valent conjugated pneumococcal vaccineOther: Peripheral blood sample

Interventions

FDA approved pneumococcal polysaccharide vaccine containing capsular polysaccharide of 23 different pneumococcal serotypes. Only group 5 will potentially receive this as an intervention.

Also known as: Pneumovax 23 or PPV23
5.Healthy young

FDA approved pneumococcal polysaccharide vaccine containing capsular polysaccharide of 13 different pneumococcal serotypes conjugated to CRM197. Only group 5 will receive this as an intervention. In all other groups Prevnar 13 will be given as standard of care.

Also known as: Prevnar 23 or PCV13
5.Healthy young

Peripheral blood samples (30-60 mL) 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. In addition, day 5, and 10 blood samples will be obtained from a limited (n=10) number of elderly RT participants to determine the optimal time point for circulation of PPS-specific B cells. Yearly blood samples will be obtained thereafter for serum antibody and OPA analyses to test longevity of antibody and OPA responses. Samples obtained from days 0, 30 and yearly samples will be used for antibody titers and opsonophagocytic assays. Samples from day 0 (day of vaccination with PCV13) and day 7 will be used for flow cytometric analysis.
