    Study Notes

    Anemia

    • Symptoms: Pallor, Fatigue, Tachycardia, Malaise, Lethargy, Dyspnea on exertion.
    • Cause: Overproduction of white blood cells (WBCs) reduces red blood cell (RBC) availability.
    • Clinical Therapies: Improve hydration and nutrition, stimulate RBC production with Epoetin, blood transfusions, rest, monitor vital signs and complete blood count (CBC).

    Infection

    • Symptoms: Fever, Night sweats, Oral ulcerations, Frequent/recurrent infections in respiratory, integumentary, urinary, and other systems.
    • Cause: Immature WBCs fail to respond effectively to pathogens.
    • Clinical Therapies: Teach hand hygiene and cough etiquette, avoid crowds, teach symptom reporting, administer antimicrobials, monitor vital signs and CBC.

    Bleeding (Thrombocytopenia)

    • Symptoms: Petechiae, Bruising, Bleeding gums, Hematuria, Hematemesis, Rectal bleeding.
    • Cause: Decreased platelets and reduced coagulation factors lead to increased bleeding risk.
    • Clinical Therapies: Monitor coagulation studies, patient education to reduce injury, administer platelets and clotting factors, monitor CBC, blood transfusions.

    Leukemic Cell Infiltration

    • Meningeal Infiltration: Increased intracranial pressure → headache, altered level of consciousness (LOC), cranial nerve impairment, nausea/vomiting.
    • Lymph Nodes, Liver, Spleen, Bone Marrow: Pain and swelling in affected tissues.
    • Kidneys: Reduced urine output, Increased blood urea nitrogen (BUN) and creatinine levels.

    Increased Metabolism

    • Symptoms: Weight loss, Heat intolerance, Dyspnea on exertion, Tachycardia.

    Uric Acid Accumulation

    • Cause: Destruction of WBCs releases large amounts of uric acid, potentially causing renal insufficiency by obstructing renal tubules.

    Anemia Treatment

    • Improve hydration and nutrition to support red blood cell production.
    • Use medications like epoetin to stimulate red blood cell production.
    • Perform blood transfusions to increase red blood cell count.
    • Encourage rest to reduce energy expenditure.
    • Monitor vital signs and complete blood count (CBC) to assess effectiveness and adjust treatment.

    Infection Prevention & Management

    • Teach infection prevention techniques, including hand hygiene, cough etiquette, and limiting exposure to crowds.
    • Educate patients on recognizing and reporting potential infection symptoms.
    • Administer antimicrobial medications as needed to treat existing infections.
    • Monitor vital signs and CBC for signs of infection.

    Management of Bleeding (Thrombocytopenia)

    • Monitor coagulation studies to assess blood clotting ability.
    • Educate patients on minimizing injury risk and preventing bleeding.
    • Administer platelets or clotting factors to address low platelet counts.
    • Monitor CBC for evidence of blood loss and assess need for transfusions.

    Treatment Overview

    • The primary aims of leukemia treatment are to alleviate symptoms, achieve remission, and potentially cure the disease.
    • Treatment methods include chemotherapy, targeted therapy, radiation therapy, and bone marrow or stem cell transplantation.
    • Chemotherapy consists of induction and consolidation phases. Induction aims to induce remission, while consolidation maintains remission.
    • Prognosis varies depending on the specific type and subtype of leukemia. While cure is more common in children, long-term remission is achievable for adults.

    Multisystem Effects of Leukemia

    • Neurologic: Headaches, altered level of consciousness, cranial nerve impairment, seizures, coma, retinal hemorrhage, subarachnoid hemorrhage can occur due to leukemia.
    • Respiratory: Dyspnea (difficulty breathing), pharyngitis (sore throat), frequent infections, and pulmonary bleeding can be seen in leukemia patients.
    • Gastrointestinal: Anorexia (loss of appetite), nausea, oral ulcerations, bleeding gums, abdominal pain, hepatomegaly (enlarged liver), and gastrointestinal bleeding are common gastrointestinal effects.
    • Urinary: Patients with leukemia may experience urinary tract infections (UTIs), hematuria (blood in urine), and renal insufficiency or failure.
    • Musculoskeletal: Weakness, bone and joint pain, and tenderness are common musculoskeletal manifestations of leukemia.
    • Metabolic: Malaise (general discomfort), heat intolerance, fever, weight loss, and night sweats can occur due to metabolic changes caused by leukemia.
    • Cardiovascular: Tachycardia (rapid heart rate), orthostatic hypotension (low blood pressure upon standing), murmurs, hematomas (bruises), edema (swelling), and hemorrhage can be observed in the cardiovascular system.
    • Hematologic: Anemia (low red blood cell count), thrombocytopenia (low platelet count), leukopenia (low white blood cell count), epistaxis (nosebleeds), and disseminated intravascular coagulation (DIC) are common hematologic effects.
    • Immunologic: Recurrent infections, lymphadenopathy (swollen lymph nodes), abscesses, and septicemia (blood poisoning) can occur due to immune system impairment.
    • Integumentary: Pallor (pale skin), petechiae (small red spots), bruising, ulcerations, and chloromas (greenish tumors) can be seen on the skin.

    Diagnostic Tests

    • Complete Blood Count (CBC) with Differential: Measures red blood cells (RBCs), white blood cells (WBCs), platelets, hemoglobin, hematocrit, and the morphology of WBCs.
    • Bone Marrow Exam: Evaluates erythropoiesis (red blood cell production) and leukopoiesis (white blood cell production). Assesses the maturity of cells within the marrow.

    Leukemia Types and Diagnostic Test Results

    • Acute Myeloid Leukemia (AML):
      • Low RBC count, hemoglobin, hematocrit, and platelet count.
      • Variable WBC count.
      • Presence of myeloblasts.
      • Decreased neutrophils.
      • Hypercellular bone marrow.
      • Presence of blasts.
    • Chronic Myeloid Leukemia (CML):
      • Low RBC count, hemoglobin, hematocrit, and platelet count (late stage).
      • Increased WBC count (early stage).
      • Increased neutrophils.
      • Hypercellular bone marrow.
      • Presence of blasts (crisis).
    • Acute Lymphoblastic Leukemia (ALL):
      • Low RBC count, hemoglobin, hematocrit, and platelet count.
      • Variable WBC count.
      • Decreased neutrophils.
      • Normal lymphocytes.
      • Hypercellular bone marrow.
      • Presence of blasts.
    • Chronic Lymphocytic Leukemia (CLL):
      • Low RBC count, hemoglobin, hematocrit, and platelet count.
      • Increased WBC count.
      • Normal neutrophils.
      • Increased lymphocytes.
      • Hypercellular bone marrow.

    Bone Marrow Transplant (BMT)

    • Allogeneic BMT: Uses bone marrow from a matched donor (sibling or unrelated)
      • Requires high doses of chemotherapy and radiation to destroy cancerous cells in the bone marrow before transplant.
      • Bone marrow is extracted from the donor and infused into the recipient through a central venous line.
    • Autologous BMT: Uses the patient's own bone marrow after achieving remission.
      • One liter of bone marrow is extracted from the iliac crest during remission.
      • Bone marrow is frozen and stored for later use if needed (e.g., after lethal doses of chemotherapy or radiation).
      • Later, the frozen bone marrow is thawed and infused intravenously through a central line.
      • Neutrophil count and normal hematopoiesis (blood cell production) should increase after the transplant.
    • Complications:
      • Infection
      • Bleeding
      • Malnutrition

    Stem Cell Transplant (SCT)

    • Allogeneic SCT:
      • An alternative to BMT, involves replacing the recipient's blood cell lines completely.
      • Recipient undergoes similar pre-transplant treatment as BMT (chemotherapy and radiation).
      • Donor receives GM-CSF/G-CSF for 4-5 days to increase stem cell concentration in blood.
      • Blood is then harvested, WBCs (white blood cells) are separated, and administered through a large central venous catheter.
    • Umbilical cord blood: Can be used as a source of stem cells in certain cases.
    • Complications:
      • Graft-versus-host disease (GVHD): T lymphocytes in the donated marrow or blood attack the recipient's tissues.
        • Acute GVHD: Usually develops within days to six months after the transplant.
          • Symptoms: Pruritic, maculopapular rash (starting on palms and soles, spreading), jaundice, diarrhea, nausea/vomiting, dry eyes.
        • Chronic GVHD: Develops more than three months after the transplant and can persist indefinitely.
          • Symptoms: Chronic pain, fatigue, weakness, shortness of breath due to lung injury.
      • Treatment for GVHD: Antibiotics and corticosteroids.
