Outcomes Of Acute Inflammation
Following the process of acute inflammation, there are several possible results:
- Complete resolution – with total repair and destruction of the insult.
- Fibrosis and scar formation – occurs in cases of significant inflammation.
- Chronic inflammation – from a persisting insult.
- Formation of an abscess.

What are the four outcomes of acute inflammation?
Inflammation | Definition, Symptoms, Treatment, & Facts Inflammation is a response triggered by damage to living, The inflammatory response is a defense mechanism that evolved in higher organisms to protect them from infection and, Its purpose is to localize and eliminate the injurious agent and to remove damaged tissue components so that the body can begin to heal.
The response consists of changes in blood flow, an increase in permeability of blood vessels, and the migration of fluid, proteins, and white blood cells () from the circulation to the site of tissue damage. An inflammatory response that lasts only a few days is called acute inflammation, while a response of longer duration is referred to as chronic inflammation.
The four cardinal signs of inflammation are redness (Latin rubor ), heat ( calor ), swelling ( tumor ), and pain ( dolor ).
Redness is caused by the dilation of small blood vessels in the area of injury.Heat results from increased blood flow through the area and is experienced only in peripheral parts of the body such as the skin. is brought about by chemical mediators of inflammation and contributes to the rise in temperature at the injury.Swelling, called, is caused primarily by the accumulation of fluid outside the blood vessels.The pain associated with inflammation results in part from the distortion of tissues caused by edema, and it also is induced by certain chemical mediators of inflammation, such as bradykinin,, and the,
Inflammation serves as a defense mechanism against infection and injury, and localizing and eliminating injurious factors and removing damaged components allows the healing process to begin. During the healing process, damaged cells capable of proliferation regenerate.
Tissue repair, resulting in formation, may occur when normal tissue architecture cannot be regenerated successfully. Failure to replicate the original framework of an organ can lead to disease. Acute inflammation is usually beneficial but often causes unpleasant sensations, such as pain or itching. In some instances inflammation can cause harm.
Tissue destruction can occur when the regulatory mechanisms of the inflammatory response are defective or the ability to clear damaged tissue and foreign substances is impaired. In other cases an inappropriate immune response may give rise to a prolonged and damaging inflammatory response.
In reactions, the body’s immune system attacks its own tissues, leading to long-term chronic inflammation. inflammation, a response triggered by damage to living, The inflammatory response is a that evolved in higher organisms to protect them from and, Its purpose is to localize and eliminate the injurious agent and to remove damaged tissue components so that the body can begin to heal.
The response consists of changes in flow, an increase in permeability of, and the migration of fluid,, and (leukocytes) from the to the site of tissue damage. An inflammatory response that lasts only a few days is called inflammation, while a response of longer duration is referred to as chronic inflammation.
Although acute inflammation is usually, it often causes unpleasant sensations, such as the of a or the of an, Discomfort is usually temporary and disappears when the inflammatory response has done its job. But in some instances inflammation can cause harm. Tissue destruction can occur when the regulatory mechanisms of the inflammatory response are defective or the ability to clear damaged tissue and foreign substances is impaired.
In other cases an inappropriate immune response may give rise to a prolonged and damaging inflammatory response. Examples include, or, reactions, in which an environmental agent such as, which normally poses no threat to the individual, inflammation, and, in which chronic inflammation is triggered by the body’s immune response against its own tissues.
- The factors that can stimulate inflammation include microorganisms, physical agents, chemicals, inappropriate immunological responses, and tissue death.
- Infectious agents such as and are some of the most common stimuli of inflammation.
- Viruses give rise to inflammation by entering and destroying cells of the body; bacteria release substances called that can initiate inflammation.
Physical trauma,,, and can damage tissues and also bring about inflammation, as can corrosive chemicals such as acids, alkalis, and oxidizing agents. As mentioned above, malfunctioning immunological responses can incite an inappropriate and damaging inflammatory response.
- Inflammation can also result when tissues die from a lack of oxygen or nutrients, a situation that often is caused by loss of blood flow to the area.
- The four cardinal signs of inflammation—redness (Latin rubor ), ( calor ), swelling ( tumor ), and pain ( dolor )—were described in the 1st century ad by the Roman medical writer,
Redness is caused by the dilation of small blood vessels in the area of injury. Heat results from increased blood flow through the area and is experienced only in parts of the body such as the skin. Fever is brought about by chemical mediators of inflammation and contributes to the rise in temperature at the injury.
Swelling, called, is caused primarily by the accumulation of fluid outside the blood vessels. The pain associated with inflammation results in part from the distortion of tissues caused by edema, and it also is induced by certain chemical mediators of inflammation, such as bradykinin,, and the, A fifth consequence of inflammation is the loss of function of the inflamed area, a feature noted by German pathologist in the 19th century.
Loss of function may result from pain that mobility or from severe swelling that prevents movement in the area. When tissue is first injured, the small blood vessels in the damaged area constrict momentarily, a process called vasoconstriction. Following this event, which is believed to be of little importance to the inflammatory response, the blood vessels dilate ( ), increasing blood flow into the area.

- Next, the walls of the blood vessels, which normally allow only water and salts to pass through easily, become more permeable.
- Protein-rich fluid, called exudate, is now able to exit into the tissues.
Substances in the exudate include factors, which help prevent the spread of infectious agents throughout the body. Other proteins include antibodies that help destroy invading microorganisms. As fluid and other substances leak out of the blood, blood flow becomes more sluggish and begin to fall out of the axial stream in the centre of the vessel to flow nearer the vessel wall.
What are the 5 outcomes of inflammation?
Introduction – Based on visual observation, the ancients characterised inflammation by five cardinal signs, namely redness ( rubor ), swelling ( tumour ), heat ( calor ; only applicable to the body’ extremities), pain ( dolor ) and loss of function ( functio laesa ).
The first four of these signs were named by Celsus in ancient Rome (30–38 B.C.) and the last by Galen (A.D 130–200), More recently, inflammation was described as “the succession of changes which occurs in a living tissue when it is injured provided that the injury is not of such a degree as to at once destroy its structure and vitality”, or “the reaction to injury of the living microcirculation and related tissues,
Acute Inflammation | Immunology
Although, in ancient times inflammation was recognised as being part of the healing process, up to the end of the 19 th century, inflammation was viewed as being an undesirable response that was harmful to the host. However, beginning with the work of Metchnikoff and others in the 19 th century, the contribution of inflammation to the body’s defensive and healing process was recognised,
Furthermore, inflammation is considered the cornerstone of pathology in that the changes observed are indicative of injury and disease. The classical description of inflammation accounts for the visual changes seen. Thus, the sensation of heat is caused by the increased movement of blood through dilated vessels into the environmentally cooled extremities, also resulting on the increased redness (due to the additional number of erythrocytes passing through the area).
The swelling (oedema) is the result of increased passage of fluid from dilated and permeable blood vessels into the surrounding tissues, infiltration of cells into the damaged area, and in prolonged inflammatory responses deposition of connective tissue.
- Pain is due to the direct effects of mediators, either from initial damage or that resulting from the inflammatory response itself, and the stretching of sensory nerves due to oedema.
- The loss of function refers to either simple loss of mobility in a joint, due to the oedema and pain, or to the replacement of functional cells with scar tissue.
Today it is recognised that inflammation is far more complex than might first appear from the simple description given above and is a major response of the immune system to tissue damage and infection, although not all infection gives rise to inflammation.
Inflammation is also diverse, ranging from the acute inflammation associated with S. aureus infection of the skin (the humble boil), through to chronic inflammatory processes resulting in remodeling of the artery wall in atherosclerosis; the bronchial wall in asthma and chronic bronchitis, and the debilitating destruction of the joints associated with rheumatoid arthritis.
These processes involve the major cells of the immune system, including neutrophils, basophils, mast cells, T-cells, B-cells, etc. However, examination of a range of inflammatory lesions demonstrates the presence of specific leukocytes in any given lesion.
- That is, the inflammatory process is regulated in such a way as to ensure the appropriate leukocytes are recruited.
- These events are controlled by a host of extracellular mediators and regulators, including cytokines, growth factors, eicosanoids (prostaglandins, leukotrines, etc), complement and peptides.
In fact, it is the discovery of many of these mediators over the past 20 years that has increased our understanding of the regulation of the inflammatory process whilst, at the same time, revealing its complexity. These extracellular events are matched by equally complex intracellular signalling control mechanisms, with the ability of cells to assemble and disassemble an almost bewildering array of signalling pathways as they move from inactive to dedicated roles within the inflammatory response and site.
- Which cells and mediators come into play depends on wide range of factors.
- These include: what stage the process of inflation is at; the initiating event, i.e.
- Type of pathogen, auto-immune, chemical or physical injury, etc.; the tissue or organ involved; whether the inflammation is of an acute, resolving form or chronic, non resolving or long-lasting type; whether formation of granuloma is involved, or whether scarring results.
The role of inflammation as a healing, restorative process, as well as its aggressive role, is also more widely recognised today. Inflammation is now considered as the full circle of events, from initiation of a response, through the development of the cardinal signs above, to healing and restoration of normal appearance and function of the tissue or organ.
- However, in certain conditions there appears to be no resolution and a chronic state of inflammation develops that may last the life of the individual.
- Such conditions include the inflammatory disorders rheumatoid arthritis, osteoarthritis, inflammatory bowel diseases, retinitis, multiple sclerosis, psoriasis and atherosclerosis.
In order to study inflammation a multidisciplinary approach is necessary. Classically, it has required the study of the immune system, in order to understand the events involved in initiating and maintaining inflammatory conditions. Today it is recognised that the underlying genetics and molecular biology basis to cellular responses are also important in order to identify genetic predisposition to inflammatory diseases, while pharmacological studies are necessary to identify targets and develop novel treatments to bring relief from chronic life-threatening inflammatory conditions.
- Thus research into inflammation includes not only the study of immunological and cellular responses involved but also the pharmacological process involved in drug development.
- Many of the drugs used in the treatment of inflammatory conditions, predate our current understanding of the biochemical processes involved in the disease.
Traditionally, the standard treatments for rheumatoid arthritis has been to use a non-steroidal anti-inflammatory drug (NSAID), such as aspirin, for pain relief and to use corticosteroids or even disease-modifying anti-rheumatic drugs in an attempt to reduce other symptoms of the disease.
For many years the pharmaceutical industry attempted to develop NSAIDs which shared the therapeutic action of aspirin but which did not cause the main adverse event, namely gastric ulceration. This research led to the development of indomethacin, the fenamates, ibuprofen and many others. However, while all these drugs had clinical utility they also eroded the gastric mucosa.
In addition, this research also led to the development of some of the animal models still used in arthritis research today, such as carrageenin oedema and adjuvant arthritis ). The development of NSAIDs, with reduced potential to cause gastric ulcers, was finally realised with the demonstration that clinically useful NSAIDs inhibited the enzyme cyclo-oxygenase, which was also present in the gastric mucosa.
- The finding that cyclo-oxygenase present in inflammatory lesions (COX2) was distinct from that found in the stomach (COX1) led to the development of selective COX2 inhibitors, such as celecoxib.
- These drugs provide relief from many of the symptoms of arthritis but have a reduced potential to cause gastric ulceration,
The differential responsiveness to these, and other, therapeutic agents and, indeed, the induction of the inflammatory response in some patients with asthma by aspirin, has led to the concept of pharmacogenomics to understand individual drug sensitivities with a view to producing therapy tailored to the individual.
Similarly, glucocorticoids are widely used in the treatment of inflammation. Unlike the NSAIDs these agents do not relieve pain but reduce inflammation by inhibiting leukocyte function. The active ingredient responsible for the anti-inflammatory activity of adrenal cortex extracts was discovered in the 1940s.
This led to the use of cortisol as an anti-inflammatory and the development of potent synthetic agents typified by dexamethasone. However, because cortisol, and synthetic glucocorticoids, produce their therapeutic action at supra-physiological concentrations, adverse effects, such as suppression of the HPA-axis and Cushingoid changes are inevitable.
Many of these adverse effects can be avoided by giving glucocorticoids topically. This has led to the development of inhaled glucocorticoids for the treatment of inflammatory diseases of the respiratory tract and steroid containing creams for the treatment of skin inflammation. However, applying this approach to the treatment of rheumatoid arthritis necessitates the use of intra-articular injection.
Thus, there is a clear unmet medical need for a drug that provides relief from the symptoms of inflammation but can be given systemically. The fact that a large number of patients with severe chronic inflammatory disease fail to respond to conventional systemic or topical therapy resulting in a huge clinical and socio-economic burdon underlies the need to develop novel therapies.
- Thus, modern research has used molecular techniques to identify which genes are regulated by glucocorticoid receptors in an attempt to identify novel therapeutic targets.
- This work has attempted to fine tune the immune system through use of agents that inhibit specific pathways and mediators rather than to suppress immune cell activity.
Examples of such approaches include the development of anti-TNFa therapies, anti adhesion molecule therapies and inhibitors of cytokines believed to be pivotal in a given pathology, Furthermore, inhibitors of selective pro-inflammatory intracellular signalling pathways are currently in use e.g.
cyclsporin or under development e.g. NF-κB, p38 MAPK and PDE4 inhibitors, As we understand more about the complexity of the inflammatory response and the actions of the currently available drugs the value of particular clusters of targets becomes apparent. However, the success of anti-TNFα therapy in RA underlines the importance of understanding/discovering the initial driver(s) of the inflammatory response in individual diseases and patients.
While research into inflammation has resulted in great progress in the latter half of the 20th century, we recognise that the rate of progress is accelerating. Furthermore, it is our perception that there is a need for a vehicle through which this very diverse research can readily be made available to the scientific community.
What is the ideal outcome of acute inflammation?
Acute inflammation and its resolution – In response to injury or infection, the protective program of acute inflammation and its complete and timely resolution are critical for the restoration of tissue homeostasis 10, This highly coordinated and synergistic program combines the distinct actions of multiple cell types to achieve pathogen eradication and subsequent tissue repair.
- The acute inflammatory response can be divided into two general phases: initiation and resolution ( Fig 1 ).
- Initiation is marked by tissue edema resulting from increased blood flow and permeability of the microvasculature; processes that are mediated in part by lipid mediators (e.g., cysteinyl leukotrienes and prostaglandins) and other vasoactive products (e.g., histamine, bradykinin).
Subsequently, polymorphonuclear neutrophils (PMN) migrate to the area to defend against microbial invasion. Drawn to the site of injury by exuded chemical signals including pro-inflammatory lipid mediators (e.g., leukotriene B 4 ; LTB 4 ) and chemokines, PMN traverse the vasculature through precise interactions with endothelial adhesion receptors and subsequently engulf and degrade pathogens within phagolysosomes 11 – 13,
The resolution phase is already being enacted at this early point as the influx of PMN is halted at a level appropriate for the insult and is accompanied by their timely apoptosis 14, Monocytes subsequently infiltrate the tissue where they differentiate into macrophages that avidly respond to pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs) present in the injured tissue.
Importantly, macrophages are highly responsive to so-called find-me and eat-me signals (e.g., nucleotides, externalized phosphatidylserine) released or presented by apoptotic cells such as PMN 10, 15, Uptake of apoptotic cells by macrophages (i.e., efferocytosis) is an anti-inflammatory process associated with decreased production of inflammatory mediators, thus coupling the initiation of inflammation to its ultimate resolution ( Fig.1 ).
- The timely clearance of microbes and apoptotic cells is required to prevent bystander tissue damage and to set the stage for tissue repair and regeneration, allowing for the return to homeostasis 9, 15,
- Indeed, active clearance of apoptotic cells is a key defining feature of resolution, as failed clearance can lead to cellular necrosis and exacerbated inflammation beyond the initial insult, impeding tissue repair.
Macrophages persist in injured tissues longer than short-lived PMN, during which time they are continuously reprogrammed in response to local cues to facilitate tissue repair and orchestrate the delicate balance of fibrosis 16 – 18, Like innate immune cells, adaptive immune cells also play critical roles in the host response to infection, resolution of inflammation and in tissue repair 19, 20, The coordinated temporal events of self-limited acute inflammation The ideal outcome of an acute inflammatory response is complete resolution. The inflammatory response can be divided into two general phases: initiation and resolution. Critical to progressing from initiation to resolution is the temporal switch in lipid mediators that are biosynthesized by leukocytes in the tissue; a process known as lipid mediator class switching.
The earliest stage of the inflammatory response is marked by tissue edema due to increased blood flow and microvascular permeability and is mediated by the release of pro-inflammatory lipid mediators including the cysteinyl leukotrienes and prostaglandins. Polymorphonuclear neutrophils (PMN) infiltrate in response to lipid mediators including leukotriene B 4 and engulf and degrade pathogens.
Subsequently, PMN undergo apoptosis and also switch from releasing pro-inflammatory mediators to pro-resolving mediators (e.g., resolvins) that signal the clearance of apoptotic cells by macrophages in an anti-inflammatory process termed efferocytosis.
In addition to promoting efferocytosis, pro-resolving lipid mediators halt further PMN recruitment and stimulate a pro-resolving macrophage phenotype that is important for tissue repair. By its nature, the acute inflammatory response is self-limiting in part because of inherent negative feedback regulation of inflammatory signaling pathways (e.g., transcriptional repressors, endogenous receptor antagonists) when the trigger has been eliminated.
However, it has recently become evident that active resolution of inflammation involves the biosynthesis of pro-resolving mediators that, as a genus, are just as diverse as the initiators of inflammation 24 – 33, Thus, critical to determining the fate of an inflammatory response is the balance of pro-inflammatory and pro-resolving mediators that are produced in the exudate in a temporal manner.
Traditionally, it has been held that an excess production of pro-inflammatory mediators underlies chronic inflammation 34, however, mounting evidence supports the view that disruptions in endogenous pro-resolving circuits may be an equally important mechanism 10, 34, 35, These pro-resolving mediators actively terminate the production of pro-inflammatory mediators, but also directly stimulate macrophage phagocytosis of both apoptotic cells and bacteria, promote egress of phagocytes from sites of inflammation, regulate PMN apoptosis, promote chemokine scavenging, and stimulate tissue repair and regeneration 9, 36 – 41,
These agonist-based actions distinguish pro-resolving mediators from intrinsic negative feedback pathways and other antagonists that terminate inflammatory signaling pathways. Systems-based approaches have played a crucial role in the identification of the principal mediators of resolution 9,
What are the main outcomes of inflammation?
INTRODUCTION – Inflammation is the immune system’s response to harmful stimuli, such as pathogens, damaged cells, toxic compounds, or irradiation, and acts by removing injurious stimuli and initiating the healing process, Inflammation is therefore a defense mechanism that is vital to health,
- Usually, during acute inflammatory responses, cellular and molecular events and interactions efficiently minimize impending injury or infection.
- This mitigation process contributes to restoration of tissue homeostasis and resolution of the acute inflammation.
- However, uncontrolled acute inflammation may become chronic, contributing to a variety of chronic inflammatory diseases,
At the tissue level, inflammation is characterized by redness, swelling, heat, pain, and loss of tissue function, which result from local immune, vascular and inflammatory cell responses to infection or injury, Important microcirculatory events that occur during the inflammatory process include vascular permeability changes, leukocyte recruitment and accumulation, and inflammatory mediator release,
- Various pathogenic factors, such as infection, tissue injury, or cardiac infarction, can induce inflammation by causing tissue damage.
- The etiologies of inflammation can be infectious or non-infectious (Table 1 ).
- In response to tissue injury, the body initiates a chemical signaling cascade that stimulates responses aimed at healing affected tissues.
These signals activate leukocyte chemotaxis from the general circulation to sites of damage. These activated leukocytes produce cytokines that induce inflammatory responses,
What are the benefits and outcome of acute inflammation?
Acute and chronic – There are two types of inflammation: acute and chronic. People are most familiar with acute inflammation. This is the redness, warmth, swelling, and pain around tissues and joints that occurs in response to an injury, like when you cut yourself.
- When the body is injured, your immune system releases white blood cells to surround and protect the area.
- Acute inflammation is how your body fights infections and helps speed up the healing process,” says Dr.
- Shmerling.
- In this way, inflammation is good because it protects the body.” This process works the same if you have a virus like a cold or the flu.
In contrast, when inflammation gets turned up too high and lingers for a long time, and the immune system continues to pump out white blood cells and chemical messengers that prolong the process, that’s known as chronic inflammation. “From the body’s perspective, it’s under consistent attack, so the immune system keeps fighting indefinitely,” says Dr.
Shmerling. When this happens, white blood cells may end up attacking nearby healthy tissues and organs. For example, if you are overweight and have more visceral fat cells — the deep type of fat that surrounds your organs — the immune system may see those cells as a threat and attack them with white blood cells.
The longer you are overweight, the longer your body can remain in a state of inflammation. Research has shown that chronic inflammation is associated with heart disease, diabetes, cancer, arthritis, and bowel diseases like Crohn’s disease and ulcerative colitis.
What are the 3 goals of inflammatory response?
The goal of inflammation is to respond to the stimuli and restore balance. Often, this includes eliminating the cause of tissue injury, clearing out necrotic or dead cells, and starting tissue repair.
What is the outcome of acute and chronic inflammation?
During acute inflammation, innate immune cells form the first line of immune defense and regulate activation of adaptive immune responses. By contrast, during chronic inflammation, these roles can be reversed — adaptive immune responses can cause ongoing and excessive activation of innate immune cells.
What are two possible outcomes of chronic inflammation?
You may be able to manage chronic inflammation with medication and diet changes. Some foods, including leafy greens, nuts, and fruit, may help reduce inflammation in the body. Inflammation refers to your body’s process of fighting against things that harm it, like infections, injuries, and toxins, in an attempt to heal itself.
- When something damages your cells, your body releases chemicals that trigger a response from your immune system,
- This response includes the release of antibodies and proteins, as well as increased blood flow to the damaged area.
- In the case of acute inflammation — like getting a cut on your knee or dealing with a cold — the whole process usually lasts for a few hours or a few days.
Chronic inflammation happens when this response lingers, leaving your body in a constant state of alert. Over time, chronic inflammation may have a negative impact on your tissues and organs. Some research suggests that chronic inflammation could also play a role in a range of conditions, from cancer to stroke,
fatigue body pain depression or anxiety gastrointestinal complications ( diarrhea or constipation )weight gainweight losspersistent infections
These symptoms can range from mild to severe and last for several months or years. Several things can cause chronic inflammation, including:
untreated causes of acute inflammation, like an infection or injuryan autoimmune disorder, which involves your immune system mistakenly attacking healthy tissuelong-term exposure to irritants, like industrial chemicals or polluted air
Keep in mind that these issues don’t cause chronic inflammation in everyone. In addition, some cases of chronic inflammation don’t have a clear underlying cause. Experts also believe that a range of factors may also contribute to chronic inflammation, like:
smoking obesity alcohol chronic stress
When you’re living with chronic inflammation, your body’s inflammatory response can eventually start damaging healthy cells, tissues, and organs. Over time, this can lead to DNA damage, tissue death, and internal scarring, All of these are linked to the development of several diseases, including:
cancer heart disease rheumatoid arthritis type 2 diabetes obesity asthma cognitive decline and dementia (in older adults)
There are no real tests to diagnose inflammation on its own. But certain blood tests are a good starting point, including ones that highlight C-reactive protein (CRP), which indicates infections or inflammation in the general body (like the joints), and high-sensitivity C-reactive protein (hsCRP), which reflects inflammation of the heart.
- Many individuals don’t know they have chronic inflammation until they’re diagnosed with another condition.
- If you feel like you’re experiencing some of the common symptoms of chronic inflammation, it’s a good idea to speak with your doctor.
- They’ll know the first steps to take when it comes to a diagnosis.
Inflammation is a natural part of the healing process. But when it becomes chronic, it’s important to try to get it under control to reduce your risk of long-term damage. Some of the options that’ve been explored for managing inflammation include:
Nonsteroidal anti-inflammatory drugs (NSAIDs). Over-the-counter NSAIDs, like aspirin, ibuprofen (Advil), and naproxen (Aleve), effectively reduce inflammation and pain. But long-term use is linked to an increased risk of several conditions, including peptic ulcer disease and kidney disease. Steroids. Corticosteroids are a type of steroid hormone. They decrease inflammation and suppress the immune system, which is helpful when it starts attacking healthy tissue. But long-term use of corticosteroids can lead to vision problems, high blood pressure, and osteoporosis, When prescribing corticosteroids, your doctor will weigh the benefits and risks with you. Supplements. Certain supplements may help to reduce inflammation. Fish oil, lipoic acid, and curcumin have all been linked to decreased inflammation — although more studies need to be done, especially around fish oil, to say for sure. Several spices may also help with chronic inflammation and inflammatory disease, including ginger, garlic, and cayenne, but again, more research around optimal dosage and definitive statements need to be done. Lifestyle changes, Losing weight (if your doctor recommends it), increasing physical activity, and dietary changes (like a low glycemic diet and reduced saturated fat intake), have all been shown to help lower inflammation.
What you eat can play both a positive and negative role in managing chronic inflammation.
What is the conclusion of inflammation?
Conclusions – Acute inflammation in response to injury or infection is adaptive and successfully supports the careful orchestration of both the innate and adaptive immune response. However, constant or repetitive activation of the immune system whether psychologically or organically (i.e., antigen, injury) related leads to long-term exposure resulting in low grade inflammation.
This chronic inflammation disrupts multiple systems due its effect on the nervous system as well as locally via cytokine receptor expression throughout multiple bodily tissues. As an integrated system, the body requires a universal way of communicating between its distinct anatomical parts, i.e., a common physiological mechanism.
Inflammation, regulated by pro- and anti-inflammatory cytokine production, may be the key to understanding how disease develops and progresses within the body. Hence, the prevailing siloed view of diseases being independent of each other and therefore needing to be managed by discrete specific interventions is no longer tenable, and as experience shows has largely limited success.
The “phenotypic” characteristics of a disease is just one representation of the disruptions in the whole system disruption, In integrated systems, the disturbance of one variable “causes” effects, cascading via multiple pathways, on other key factors and invariably is associated with feedback to modulate the behavior of the “causative variable.” For example, external and internal factors can result in the same phenotypical outcome; low socioeconomic status and excessive adipose tissue both are linked to chronic inflammation.
This elevated inflammation leads to increased brain cytokine signaling and impairs learning and memory and supports depressive symptoms or sickness behavior ; this feedback results in further propagation of the negative or unhealthy systemic cycle. Thus, uncontrolled or dysregulated inflammation unites the manifestation of chronic physical and mental diseases that often are prevalent in high-stress, vulnerable populations (e.g., ethnic minority, lower socioeconomic status, etc.).
What are the four systemic effects of inflammation?
Clinical Significance – The signs of inflammation include loss of function, heat, pain, redness, and swelling. Inflammation is part of the body’s complex biological response to harmful stimuli, such as irritants, pathogens, and damaged cells. It is clinically useful to differentiate inflammation and infection as there are many pathological situations where distinguishing them is highly essential to evaluation and treatment.
