Filter by:Background: The immune system defends the body against disease and infection. Immune deficiencies are health conditions that decrease the strength of this response. Vaccines stimulate the immune system to create a defense against a specific type of germ. Researchers want to compare immune system responses to COVID-19 vaccines in people with and without immune deficiencies. Objective: To learn about how people with immune deficiencies respond to COVID-19 vaccines. Eligibility: People age 3 and older with an immune deficiency who plan to get a COVID-19 vaccine. Healthy volunteers are also needed. Design: Participants will be pre-screened for eligibility, including COVID-19 vaccination history and immune status. Participants will give a blood sample before they get their first COVID-19 vaccine. Blood will be drawn from an arm vein using a needle. Blood can be drawn at the NIH, at a local doctor's office, or at a laboratory. It may also be drawn through a fingerstick at home. Participants will also complete 2 online surveys about their health and COVID-19 history. Additional surveys are optional. Participants will give a second blood sample 2 to 4 weeks after they get the vaccine. They will complete 2 surveys about changes in their health and side effects from the vaccine. If participants get another COVID-19 vaccine dose, they will repeat the blood draw and surveys 3 to 4 weeks later. Participants may give 3 optional blood samples in the 24 months after their last vaccine. They may also give saliva samples every 2 weeks while they are in the study for 6 months following their last vaccine. Participation will last from 1 month to 2 years after the participant's last vaccine.
Melphalan is a chemotherapy drug used extensively in bone marrow transplantation. The goal of this study is to determine what causes some children to have different drug concentrations of melphalan in their bodies and if drug levels are related to whether or not a child experiences severe side-effects during their bone marrow transplant. The hypothesis is that certain clinical and individual factors cause changes in melphalan drug levels in pediatric bone marrow transplant patients and that high levels may cause severe side-effects.
Fludarabine and clofarabine are chemotherapy drugs used extensively in bone marrow transplantation. The goal of this study is to determine what causes some children to have different drug concentrations of clofarabine and fludarabine in their bodies and if drug levels are related to whether or not a child experiences severe side-effects during their bone marrow transplant. The hypothesis is that clinical and individual factors cause changes in clofarabine and fludarabine drug levels in pediatric bone marrow transplant patients and that high levels may cause severe side-effects.
The primary objective of this protocol is to expand access for patients who lack a fully HLA (Human leukocyte antigen) matched sibling donor, and who are candidates for allogeneic hematopoietic stem cell transplant (HSCT). These patients have a serious or immediately life-threatening disease for which HSCT is indicated. These patients are not eligible for other Children's Hospital of Philadelphia Institutional Review Board (IRB) approved protocols that utilize CliniMACs technology for T depletion.
This is a Phase II trial to determine the ability of a reduced intensity conditioning regimen to allow successful engraftment with alpha/beta T and CD19+ depleted peripheral stem cell grafts from unrelated or partially matched related donors. There are two conditioning regimens depending upon patient diagnosis and age.

This is a Phase II trial to determine the ability of a reduced intensity conditioning regimen to allow successful engraftment with CD3+ /CD19+ depleted peripheral stem cell grafts from mismatched donors. There are two conditioning regimens depending upon patient diagnosis and age.
The purpose of this study is to evaluate a novel screening test to detect patients with primary immunodeficiencies(PIDs). The investigators plan to use information gained from this study in order to advance the field of clinical immunology, thus improving the diagnosis, treatment, and well-being of future patients. The purpose of this study is to determine if this screening test is able to detect patients with immune problems, and the investigators will test patients with known PIDs to determine if the test is accurate The investigators hypothesize that detecting serum immunoglobulins from dried blood spots will be effective in detecting patients with known primary immunodeficiencies. If our hypothesis is confirmed, it opens the possibility of using point of care testing to screen for primary immune deficiencies. Age of study subjects will range from 1 year to 80 years of age, and will be recruited form the Immunodeficiency clinic at the Medical College of Wisconsin/Children's Hospital of Wisconsin (MCW/CHW). Any subject having testing done to evaluate the immune system is eligible for this study. This will include patients with known PIDs as well as patients evaluated for a suspected immunodeficiency. It is anticipated that 150 subjects will be analyzed over a two year period.
This is a treatment guideline for a second or greater allogeneic hematopoietic stem cell transplant (HSCT) using a reduced intensity conditioning (RIC) in patients with non-malignant or malignant diseases. This regimen, consisting of busulfan, fludarabine, and low dose total body irradiation (TBI), is designed to promote engraftment in patients who failed to achieve an acceptable level of donor-derived engraftment following a previous allogeneic HCT.
Fludarabine is a chemotherapy drug used extensively in bone marrow transplantation. The goal of this study is to determine what causes some children to have different drug concentrations of fludarabine in their bodies and if drug levels are related to whether or not a child experiences severe side-effects during their bone marrow transplant. The hypothesis is that clinical and genetic factors cause changes in fludarabine drug levels in pediatric bone marrow transplant patients and that high levels may cause severe side-effects.
