Jehovah's Witness Patients: Interventions for Successful Stem Cell Transplantation Without Blood Product Transfusions for Hematologic Malignancies

BACKGROUND

Jehovah's Witnesses are members of a religion that prohibits them from accepting blood product transfusions. This refusal makes them a particularly compelling population in the context of hematologic malignancies and stem cell transplantation, because blood product transfusions are a mainstay of supportive treatment.

OBJECTIVES

This article presents preventive and supportive measures allowing Jehovah's Witness patients the opportunity to receive a stem cell transplantation without blood product transfusions.

METHODS

A literature review was done that included evidence focusing on optimizing hematopoiesis, blood loss prevention, alterations in chemotherapy regimens, and implications for nursing practice.

FINDINGS

With proper preventive and supportive care measures, Jehovah's Witness patients can receive stem cell transplantations for hematologic malignancies without blood product transfusions.

Antineoplastic chemotherapy in Jehovah's Witness patients with acute myelogenous leukemia refusing blood products - a matched pair analysis

BACKGROUND

Acute myelogenous leukemia (AML) may be cured in a substantial number of patients using intensive chemotherapeutic regimens leading to temporary severe myelosuppression. Patients belonging to the denomination of Jehovah's Witnesses (JW), however, are bound by their religious convictions not to accept blood products and are therefore at higher risk for life-threatening events. Reports how to handle this challenge are mainly anecdotal.

MATERIAL AND METHODS

We here report in much more detail about our experience with nine patients belonging to the denomination of JW who were treated for AML in our department from 1998 to 2007 and who explicitly wished to receive chemotherapy without blood transfusions.

RESULTS

Reduced dose induction chemotherapy administered by several treatment cycles to prevent sustained myelosuppression still led to complete remissions in three out of nine of JW patients but was associated with a high rate of relapse. No durable remission was achieved. The overall hazard ratio for death was 12.1 compared to a matched control group treated with full transfusion support. The predominant cause of non-AML mortality was severe anemia (four out of five early deaths) and uncontrollable bleeding (n = 1).

CONCLUSION

Reduced dose chemotherapy without transfusion support in JW suffering from AML is associated with a lower rate of remission, high mortality by severe anemia and very low chances for long-term remissions. Less hematotoxic treatment options including hypomethylating agents or molecular targeted therapies with intensive consolidation after improvement of bone marrow function are promising for these patients but need further investigation.

How I treat acute myeloid leukemia presenting with preexisting comorbidities

Acute myeloid leukemia (AML) is a devastating disease with an incidence that progressively increases with advancing age. Currently, only ∼40% of younger and 10% of older adults are long-term survivors. If untreated, the overall prognosis of AML remains dismal. Initiation of therapy at diagnosis is usually urgent. Barriers to successful therapy for AML are the attendant toxicities directly related to chemotherapy or those associated with inevitable aplasia. Organ dysfunction often further complicates such toxicities and may even be prohibitive. There are few guidelines to manage such patients and the fear of crossing the medico-legal abyss may dominate. Such clinical scenarios provide particular challenges and require experience for optimal management. Herein, we discuss select examples of common pretreatment comorbidities, including cardiomyopathy, ischemic heart disease; chronic renal failure, with and without dialysis; hepatitis and cirrhosis; chronic pulmonary insufficiency; and cerebral vascular disease. These comorbidities usually render patients ineligible for clinical trials and enormous uncertainty regarding management reigns, often to the point of withholding definitive therapy. The scenarios described herein emphasize that with appropriate subspecialty support, many AML patients with comorbidities can undergo therapy with curative intent and achieve successful long-term outcome.
