We provide diagnosis and treatment for newborns, children and adolescents with transplantable immunodeficiencies, including newborn screening for severe combined immunodeficiency.

Our immunologists and physicians from the Blood & Marrow Transplant program work together to provide multidisciplinary care for immune-deficient patients with conditions that require hematopoietic stem cell transplantation.

Immune deficiencies we treat include:

• Severe combined immunodeficiency (SCID)
• Chronic granulomatous disease (CGD)
• Combined immunodeficiency (CID), including variants of genetically defined common variable immunodeficiency (CVID) and hyper IgM syndrome
• Wiskott–Aldrich syndrome
• DiGeorge syndrome and other variants of thymic aplasia
• Other transplantable immune deficiencies

We are a designated center for newborn screening for the rare genetic disorder severe combined immunodeficiency (SCID), by the Florida Department of Health. SCID affects a subset of white blood cells called lymphocytes that help fight infections. Our team has a special focus on the evaluation of SCID involving T cells, as well as B and NK cells in certain cases, with care provided by Jolan Walter, M.D., Ph.D. When detected early SCID can be treated with a stem cell transplant.

The team includes Deepakbabu Chellapandian, M.D., with the Center for Cell and Gene Therapy for Nonmalignant Conditions at Johns Hopkins All Children's.

We also assist our pediatric patients in transitioning to adult care when they reach the appropriate age. Johns Hopkins All Children’s is the only pediatric affiliate of the H. Lee Moffitt Cancer Center, and Dr. Walter also treats patients at part of Moffitt’s immunology transplant clinic. This allows us to provide continuity of care, provide additional treatment options for young adult patients requiring transplant for primary immunodeficiencies and develop new and innovative therapies for our patients.

Diagnostic evaluation is supported by the hospital’s Jeffrey Modell Diagnostic and Research Center for Primary Immunodeficiencies, directed by Dr. Walter. The center supports the early diagnosis and study of genetic immune deficiencies and therapies targeting these rare inherited diseases.
