                     Bone Marrow Transplantation

          Bone marrow transplantation is the aspiration of marrow from the posterior
          iliac crest of a marrow donor with the use of regional or general anesthesia and
          the IV transfusion of the marrow into a donor-matched recipient. The three
          kinds of bone marrow transplants are autologous bone marrow transplant
          (patient’s own), allogeneic bone marrow transplant (from a donor), and umbilical
          cord blood transplant (stem cells from a newborn baby’s umbilical cord imme-
          diately after birth).
          Procedure
          Before being ready to receive the transplant, the patient must:
          ■ Undergo high-dose chemotherapy, radiation, or both (myeloablative treat-
            ment) or lower doses of chemotherapy and radiation (nonmyeloablative) in
            an effort to treat the underlying disease and overcome rejection.
          ■ Be treated with immunosuppressive drugs to decrease the risk of rejection.
            T factors influencing the outcome of bone marrow transplantation include:
            ■ Disease status at transplantation
            ■ Type of donor
            ■ Recipient’s age
            ■ Comorbid medical conditions
          Early-Stage Complications
          The time of greatest risk is between 0 and 100 days.
          ■ Rejection
          ■ Mucositis, pain issues secondary to oral ulcerations and reactive herpes
            virus; oral nutritional deficits secondary to oral pain
          ■ Hemorrhage, caused by chronic thrombocytopenia and tissue injury; can be
            life threatening, but rare
          ■ Common minor bleeding, such as petechiae, epistaxis, or GI or GU bleeding
            (not life-threatening, but worrisome to patients)
          ■ Infections
            ■ Bacterial; usually gram-positive, but can be gram-negative
            ■ Fungal
            ■ Viral; can be life-threatening to these patients
          ■ Acute graft-versus-host disease: One of the most serious and challenging
            complications; caused by immunologically competent donor-derived T cells
            that react with recipient tissue antigens
          ■ Veno-occlusive disease of the liver: One of the most feared complications;
            signs and symptoms include unexplained weight gain, jaundice, abdominal
            pain, and ascites
