Is boosting the immune system in sepsis appropriate?
Critical Care (London, England)
|June 3, 2014
Summary
Severe insults like sepsis can cause immunosuppression, but boosting the immune system needs careful consideration. Immune responses vary by pathogen and tissue, and overstimulation can harm organs.
Area of Science:
- Immunology
- Critical Care Medicine
- Pathophysiology
Background:
- Severe insults (sepsis, trauma, burns) induce a state of relative immunosuppression.
- Current strategies propose immune-boosting therapies for selected patients.
- However, the immune response is complex and context-dependent.
Purpose of the Study:
- To highlight the importance of considering pathogen type, timing, and tissue specificity in immune modulation.
- To caution against universally applied immune-stimulatory interventions.
- To emphasize the nuanced nature of host immune responses after critical illness.
Main Methods:
- Review of existing literature on immune responses post-insult.
- Analysis of leukocyte immune status in different tissues.
- Conceptual framework for evaluating immunomodulatory therapies.
Main Results:
- Immune suppression is not uniform across all leukocytes or tissues.
- Activated leukocytes in specific tissues can contribute to organ failure.
- Immune status varies significantly based on insult type and timing.
Conclusions:
- Immune-boosting therapies require a highly personalized approach.
- Therapeutic interventions must account for tissue-specific immune activation.
- Potential deleterious effects of immune stimulation must be carefully weighed against benefits.

01:25Acute Inflammation II: Local and Systemic Effects
48
Acute inflammation produces a coordinated set of local and systemic changes that limit injury, eliminate pathogens, and initiate repair. These responses arise within minutes of infection, trauma, or chemical insult and are driven by vascular alterations and leukocyte-derived mediators. When the stimulus resolves, the reaction typically abates within days.Local EffectsAt the site of injury, arteriolar vasodilation increases blood flow, resulting in redness and warmth. Simultaneously, increased...

01:26Factors Affecting the Risk of Infection
14.1K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

01:23Antimicrobial Proteins
10.6K
Antimicrobial proteins are important components of the immune system. They aid the body in combating pathogens by either killing them directly or hindering their replication processes. Four main types of antimicrobial substances are interferons, the complement system, iron-binding proteins, and antimicrobial proteins.
Interferons
Interferons (IFNs) are proteins produced by lymphocytes, macrophages, and fibroblasts infected with viruses. While IFNs cannot prevent viruses from entering and...

01:29Acute Respiratory Failure-V
742
The treatment for acute respiratory failure varies based on factors like the underlying cause, overall health, and severity. A collaborative healthcare team is essential for early detection, often through arterial blood gas analysis. Identifying the cause is the primary goal, with treatment strategies adjusted for ventilation/perfusion (V/Q) mismatch, shunting, or diffusion impairment.

01:31Defense Against Bacterial Pathogens
3.0K
The human immune system is a complex network of cells, tissues, and organs that work together to defend the body against bacterial infections. It consists of various immune cells, each playing a specific role in the defense mechanism.
Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...

01:26Defense Mechanism Against Infection
9.6K
Natural flora, body system defenses, and inflammation are natural barriers of the body against infectious agents regardless of previous exposure. Normal floras of the human body refer to the microbial population that colonizes the skin and mucous membranes.
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...
