Study Notes
Components of Hematopoietic System
- Bone marrow and cells derived from it (e.g. red cells, platelets, granulocytes, and monocytes)
- Lymphoid tissues (e.g. thymus, lymph nodes, and spleen)
Hematopoietic Stem Cells (HSCs)
- Pluripotent cells that give rise to all blood cells
- Possess two essential properties: pluripotency and self-renewal
- HSCs arise in the mesoderm of the intraembryonic aorta/gonad/mesonephros region during embryonic development
- HSCs migrate to the liver, then to the bone marrow, and finally to the peripheral blood
Blood Cell Development
- HSCs give rise to committed progenitors, which differentiate into specific types of blood cells
- Colony-forming units (CFUs) are committed progenitors that produce colonies of specific blood cells
- Progenitors differentiate into morphologically recognizable precursors, such as myeloblasts, proerythroblasts, and megakaryoblasts
Regulation of Hematopoiesis
- Hematopoietic growth factors regulate the production of blood cells
- Growth factors, such as erythropoietin, granulocyte-macrophage colony-stimulating factor (GM-CSF), and granulocyte colony-stimulating factor (G-CSF), act on specific receptors to stimulate the production of specific blood cells
- Feedback loops involving growth factors maintain the balance of blood cell production
Diseases of Hematopoiesis
- Defects in hematopoiesis can lead to deficiencies in one or more types of blood cells
- Primary tumors of hematopoietic cells can interfere with marrow function
- Genetic diseases, infections, toxins, and nutritional deficiencies can also decrease blood cell production
Leukopenia
- A decrease in the number of circulating white blood cells
- Can be caused by reduced numbers of neutrophils (neutropenia, granulocytopenia) or lymphocytes (lymphopenia)
- Can occur due to ineffective hematopoiesis, suppressed bone marrow function, or increased destruction of white blood cells
Agranulocytosis
- A marked reduction in neutrophils
- Can be caused by inadequate or ineffective granulopoiesis, or increased destruction or sequestration of neutrophils
- Consequences include susceptibility to infections, particularly bacterial and fungal infections
Reactive Proliferations of White Cells
- Leukocytosis: an increase in the number of white blood cells in the blood, often in response to infection or inflammation
- Pathogenesis involves the release of cytokines, growth factors, and adhesion molecules that stimulate the production and release of white blood cells
Disorders of White Blood Cells
- Leukopenias: deficiencies of white blood cells
- Proliferative disorders: expansions of white blood cells, including reactive and neoplastic proliferations
- Neoplastic disorders: malignant proliferations of white blood cells, including leukemias### Leukocytosis
- Leukocytosis is a rapid increase in the egress of mature granulocytes from the bone marrow pool, mediated by tumor necrosis factor (TNF) and interleukin-1 (IL-1)
- Prolonged infection or inflammation stimulates macrophages, bone marrow stromal cells, and T cells to produce increased amounts of hematopoietic growth factors
- Growth factors stimulate the proliferation and differentiation of committed granulocytic progenitors, leading to a sustained increase in neutrophil production
Mechanisms of Leukocytosis
- Increased marrow production:
- Chronic infection or inflammation (growth factor-dependent)
- Paraneoplastic (e.g., Hodgkin lymphoma; growth factor-dependent)
- Myeloproliferative neoplasms (e.g., chronic myeloid leukemia; growth factor-independent)
- Increased release from marrow stores:
- Acute inflammation (e.g., with infection)
- Chronic inflammation (many causes)
- Decreased margination:
- Exercise
- Catecholamines
- Decreased extravasation into tissues:
- Glucocorticoids
Leukocytosis Types and Causes
- Neutrophilic leukocytosis:
- Causes: tissue necrosis (e.g., myocardial infarction, burns), allergic disorders, parasitic infestations, and certain malignancies
- Eosinophilic leukocytosis (eosinophilia):
- Causes: allergic disorders, parasitic infestations, and certain malignancies
- Basophilic leukocytosis (basophilia):
- Rare, often indicative of a myeloproliferative neoplasm
- Monocytosis:
- Causes: chronic infections, bacterial endocarditis, rickettsiosis, and malaria
- Lymphocytosis:
- Causes: viral infections, infectious mononucleosis, and certain autoimmune disorders
Lymphadenitis
- Lymph nodes are discrete, encapsulated structures that contain separate B-cell and T-cell zones
- Activation of resident immune cells leads to morphologic changes in lymph nodes
- Within several days of antigenic stimulation, primary follicles enlarge and develop pale-staining germinal centers
Acute Nonspecific Lymphadenitis
- Caused by bacterial infections, viral infections, and inflammatory disorders
- Morphologic changes: swollen nodes, gray-red color, and engorged sinuses
- Microscopic features: prominent reactive germinal centers, numerous mitotic figures, and scattered neutrophils
Chronic Nonspecific Lymphadenitis
- Caused by chronic infections, autoimmune disorders, and inflammatory disorders
- Morphologic changes: swollen nodes, mild increase in germinal centers, and scattered macrophages
- Microscopic features: follicular hyperplasia, paracortical hyperplasia, and sinus histiocytosis
Hemophagocytic Lymphohistiocytosis
- Characterized by cytopenias and systemic inflammation related to macrophage activation
- Triggers: infection, autoimmune disorders, and cancer
- Pathogenesis: macrophage activation, phagocytosis of blood cell progenitors, and suppression of hematopoiesis
- Clinical features: fever, splenomegaly, hepatomegaly, anemia, thrombocytopenia, and very high levels of inflammatory mediators### Lymphoid Neoplasms
- Lymphoid neoplasms are cancers that affect the immune system, particularly the white blood cells (lymphocytes).
- They are classified into two main categories: B-cell neoplasms (85-90% of cases) and T-cell neoplasms.
Precursor B-Cell Neoplasms
- B-cell acute lymphoblastic leukemia/lymphoma (B-ALL) is a type of precursor B-cell neoplasm.
- B-ALL is typically seen in children, but it can occur in adults as well.
- Acute lymphoblastic leukemia/lymphoma (ALL) is a neoplasm composed of immature B (pre-B) or T (pre-T) cells, referred to as lymphoblasts.
Peripheral B-Cell Neoplasms
- Chronic lymphocytic leukemia/small lymphocytic lymphoma is a type of peripheral B-cell neoplasm.
- It is characterized by the accumulation of mature B cells in the bone marrow and lymph nodes.
Precursor T-Cell Neoplasms
- T-cell acute lymphoblastic leukemia/lymphoma (T-ALL) is a type of precursor T-cell neoplasm.
- T-ALL is typically seen in adolescents and young adults.
Peripheral T-Cell and NK-Cell Neoplasms
- Peripheral T-cell lymphoma, unspecified, is a type of peripheral T-cell neoplasm.
- Extranodal NK/T-cell lymphoma, nasal type, is a type of peripheral T-cell and NK-cell neoplasm.
Hodgkin Lymphoma
- Hodgkin lymphoma is a type of lymphoid neoplasm that is characterized by the presence of Reed-Sternberg cells.
- It is typically seen in young adults and is often associated with Epstein-Barr virus (EBV) infection.
Pathogenesis of Lymphoid Neoplasms
- Lymphoid neoplasms can arise from genetic mutations, particularly in genes involved in B-cell and T-cell development.
- Chromosomal translocations and gene mutations can lead to the formation of oncogenic proteins that promote cell growth and proliferation.
Risk Factors for Lymphoid Neoplasms
- Genetic factors, such as inherited genetic syndromes, can increase the risk of developing lymphoid neoplasms.
- Exposure to carcinogens, such as benzene, can also increase the risk.
- Infections, such as EBV and human T-cell leukemia virus-1 (HTLV-1), can increase the risk of developing certain types of lymphoid neoplasms.
Clinical Features of Lymphoid Neoplasms
- Lymphoid neoplasms can present with a range of symptoms, including fatigue, fever, and lymph node enlargement.
- Diagnosis is typically made by histologic examination of lymph node biopsies or bone marrow aspirates.
Classification of Lymphoid Neoplasms
- The World Health Organization (WHO) classification of lymphoid neoplasms is based on the cell of origin and the morphologic, immunophenotypic, and genetic features of the neoplasm.
- The classification includes five broad categories: precursor B-cell neoplasms, peripheral B-cell neoplasms, precursor T-cell neoplasms, peripheral T-cell and NK-cell neoplasms, and Hodgkin lymphoma.
