Langley and Pain (1994) discuss some of the options for medical treatment, while Stanley et al. Artnal and Wilkinson (1998) give a case study of fulminant failure from paracetamol. Clinical scenario Fabio Galvani is a 26-year-old male who has recently completed a six-month backpacking trip to southeast Asia. Since his return he has been feeling increasingly unwell with nausea, vomiting, fever with influenza-like symptoms. He was admitted to hospital for investigations after behaving in a confused and agitated manner. Doctors made a diagnosis of fulminating hepatic failure and grade 3 hepatic encephalopathy. Review your understanding of hepatitis B virus: • Likely route (portal of entry) and mode of transmission • Incubation period • Survival outside host cells (how long virus can live outside body) • Infectious risk to friends, family and health care workers. Specify proactive nursing strategies, which can minimise potential complications (prioritising care, type of psychological support, nutrition, health promotion, use of specialists). Immunity Classifications of immunity derive from historical schools of immunology, which increasingly recognised that different modes of immunity existed concurrently. Nonspecific immunity is any defence mechanism not targeting specific microorganisms. Specific immunity is necessarily acquired through exposure to various organisms or antibody vaccination. Cell-mediated immunity causes T-lymphocytes to respond to (nonspecific) protein by producing various lymphokines; humoral immunity is mediated by antibodies (B-lymphocytes) in the blood, and is antigen-specific. Nonspecific immunity Many body systems include defence mechanisms against foreign material, all potentially compromised by critical illness and treatments (e. Specific immunity Specific immunity is achieved through two types of lymphocytes: T and B. T-lymphocytes T-lymphocyte precursors originate in bone marrow, migrating to and maturing in the thymus gland (Abbas et al. Antigen recognition by T-lymphocytes causes enlargement and differentiation into (Johnson 1994): ■ killer cells (cytolytic) attach to invading cells, then secrete • lymphotoxins (kill invading cells) • lymphokines (attract lymphocytes and macrophages) • interferon (inhibits viral replication, enhances action of killer cells) ■ helper cells assist B-lymphocytes increase antibody production (Johnson 1994). Intensive care nursing 386 B-lymphocytes B-lymphocytes, produced in the bone marrow, respond to foreign antigens by becoming antibody producing cells (Abbas et al. Three (IgA, IgG, IgM) primarily neutralise toxins and viral activity, promoting bacterial lysis and phagocytosis. IgA Relatively unimportant for systemic humoral immunity, this is found mainly in mucus membranes (Abbas et al. IgE This attaches to cell membranes of basophils and mast cells, triggering histamine (Young-McCaughan & Jennings 1998). Readily entering tissue spaces, IgG coats micro-organisms prior to phagocytosis (Hudak et al. IgM This is the first immunoglobulin secreted during primary immune response to antigens (Young-McCaughan & Jennings 1998). Immunodeficiency Failure of the immune system is usually secondary to either autoimmune pathologies (e. The immune system can also be over-whelmed by infection or complex surgery/invasive treatment, exposing patients to opportunistic infections (e. During healthy maturation T-lymphocytes are exposed to self-antigens, developing tolerance so that surviving T-lymphocytes tolerate the body’s own tissue (Abbas et al. Steroids Despite variable use over many decades to treat various conditions, steroid therapy remains controversial, tending to treat symptoms (inflammation) rather than causes.
