Pilot Study of Unrelated Donor Hematopoietic Stem Cell Transplantation in Patients With Life Threatening Hemophagocytic Disorders

• Status: Unknown status
• Trial end date: 1969-12-31

Summary

OBJECTIVES: I. Determine the efficacy of unrelated donor hematopoietic stem cell transplantation in the treatment of patients with life threatening hemophagocytic disorders.

II. Determine the rate of disease free survival, incidence of graft failure, and incidence of graft versus host disease in these patients after undergoing this treatment regimen.

• Phase: N/A
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Fairview University Medical Center
• Treatments: Antilymphocyte Serum; Busulfan; Cyclophosphamide; Cyclosporine; Cyclosporins; Etoposide; Methotrexate

Criteria

PROTOCOL ENTRY CRITERIA:

--Disease Characteristics--

• Hemophagocytic lymphohistiocytosis (HLH)

• Fever greater than 38.5 degrees Celsius

• Splenomegaly (greater than 3 cm below costal margin)

• Hemophagocytosis in bone marrow or spleen or lymph nodes

• Disease may be confirmed by positive family history

• No evidence of malignancy

• Hypertriglyceridemia and/or hypofibrinogenemia

• Fasting triglycerides at least 2.0 mmol/L or at least 3 standard deviations above normal for age

• Fibrinogen no greater than 1.5 g/L or no greater than 3 standard deviations above normal

• Cytopenia (affecting at least 2 of 3 lineages in the peripheral blood)

• Hemoglobin less than 9.0 g/L

• Platelet count less than 100,000/mm3

X-linked lymphoproliferative disorder (XLP)

Two or more maternally related males manifesting at least one of the following XLP phenotypes:

• Fulminant infectious mononucleosis

• Dysgammaglobulinemia

• Malignant lymphoma/lymphoproliferative disorder

• Aplastic anemia

• Lymphoid granulomatosis/vasculitis OR

• A maternally related male in an established XLP kindred who has strong genetic (RFLP) linkage to the XLP locus

Chediak-Higashi syndrome

Partial oculocutaneous albinism (hair, skin, eyes)

Frequent bacterial infections

Large peroxidase positive granules in leukocytes of peripheral blood or bone marrow

Positive family history or parental consanguinity is supportive of the diagnosis

May not have entered accelerated phase as defined by any of the following:

• Lymphadenopathy

• Pancytopenia

• Histiocytes with hemophagocytosis in bone marrow, lymph nodes, liver, or spleen

Viral associated hemophagocytic syndrome (VAHS)

Relapsed after prior therapy or supportive care

Diagnostic criteria as for HLH

No hemophagocytic disorders secondary to underlying malignancy

Patients 35 years of age and under must have a hematopoietic stem cell donor that is one of the following:

• HLA A and B identical OR

• Single HLA A or B serologic mismatch with DRB1 identity OR

• HLA A or B serologic identity with a single DRB1 mismatch

Patients 36 to 55 years of age must have a hematopoietic stem cell donor that is one of the following:

• HLA A and B and HLA DRB1 identical OR

• Single HLA A or B serologic mismatch with DRB1 identity

Patients receiving umbilical cord blood must have an unrelated donor with no more than two antigen HLA A, B, or DRB1 mismatches
