[Microphagal system in inflammatory and infectious processes].

V N Galankin, K V Botsmanov

    Arkhiv Patologii
    |January 1, 1982
    PubMed
    Summary

    Disorders in polymorphonuclear leukocytes (PMNL) impair immune function, leading to increased susceptibility to inflammatory-infectious processes (IIP). A healthy PMNL system is crucial for defense, while its dysfunction signifies reduced host resistance, notably in sepsis.

    Area of Science:

    • Immunology
    • Cell Biology
    • Infectious Diseases

    Background:

    • Polymorphonuclear leukocytes (PMNL) play a critical role in host defense against pathogens.
    • Inflammatory-infectious processes (IIP) involve complex interactions between pathogens and the host immune system.
    • Serum factors influence PMNL functions like leukotaxis and bactericidal activity.

    Purpose of the Study:

    • To review and synthesize current knowledge on PMNL disorders in IIP.
    • To elucidate the relationship between PMNL system function and host defense capacity.
    • To characterize PMNL system dysfunction in the context of sepsis.

    Main Methods:

    • Literature review and synthesis of existing data on PMNL function and IIP.
    • Analysis of the role of serum factors in modulating PMNL activity.
    • Correlation of PMNL system status with clinical manifestations of reduced host defense.

    Main Results:

    • IIP can develop not only with optimal PMNL phagocytosis but also with deficiencies in PMNL system function.
    • A structurally and functionally intact PMNL system is essential for maintaining good health.
    • Disorders within the PMNL system are functionally equivalent to clinical states of reduced host defense and antibacterial resistance.
    • Sepsis is associated with severe impairments in the PMNL system.

    Conclusions:

    • PMNL system integrity is fundamental for effective host defense.
    • Dysfunction of the PMNL system is a key factor in the pathogenesis of IIP and reduced nonspecific antibacterial resistance.
    • Understanding PMNL system disorders provides insights into clinical conditions like sepsis and general immune deficiency.
