Chronic inflammation is also referred to as slow, long-term inflammation lasting for prolonged periods of several months to years. Generally, the extent and effects of chronic inflammation vary with the cause of the injury and the ability of the body to repair and overcome the damage.
The most common reasons for chronic inflammation include: Autoimmune disorders, such as lupus, where your body attacks healthy tissue. Exposure to toxins, like pollution or industrial chemicals. Untreated acute inflammation, such as from an infection or injury.
Symptoms of acute inflammation last a few days. Subacute inflammation lasts 2–6 weeks . Chronic inflammation can continue for months or years.
As inflammation progresses, however, it begins to damage your arteries, organs and joints. Left unchecked, it can contribute to chronic diseases, such as heart disease, blood vessel disease, diabetes, obesity, cancer, Alzheimer's disease and other conditions.
How do you know if you have chronic inflammation? A blood test measures a protein produced by the liver, C-reactive protein (CRP), which rises in response to inflammation. A CRP level between 1 and 3 milligrams per liter of blood often signals a low, yet chronic, level of inflammation.
Left unaddressed, chronic inflammation can damage healthy cells, tissues and organs, and may cause internal scarring, tissue death and damage to the DNA in previously healthy cells. Ultimately, this can lead to the development of potentially disabling or life-threatening illnesses, such as cancer or Type-2 diabetes.
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).
Blood tests which detect inflammation are not sensitive enough to diagnose serious underlying conditions, generating an 85% false positive rate and a 50% false negative rate when used for this purpose, according to new research.
Chronic inflammation can contribute to an overproduction of inflammatory cytokines. As the body gets flooded with these molecules during chronic inflammation, the cytokines actually begin to attack healthy joint and muscle tissue, resulting in pain, swelling, redness, and stiffness.
Erythrocyte sedimentation rate (ESR)
This test works by measuring how long it takes for red blood cells to fall to the bottom of a test tube. The quicker they fall, the more likely it is there are high levels of inflammation.
A good example of chronic inflammatory disease is rheumatoid arthritis. This is an autoimmune disorder and inflammatory disease in which the immune system mistakenly attacks the joints, causing pain, inflammation, and joint damage.
The C-reactive protein (CRP) test is a blood test that checks for inflammation in your body. CRP is a protein that is made in your liver and released into your bloodstream. Levels of CRP start to increase very soon after any inflammation or infection affects your body.
A CRP test may be used to help find or monitor inflammation in acute or chronic conditions, including: Infections from bacteria or viruses.
In summary, preliminary evidence suggests that acute and chronic stress is associated with increased inflammatory activity and enhanced attentional processing of negative information. Both are predictive of negative mood and depression symptoms that, in turn, increase inflammatory and cognitive stress reactivity.
What are the signs of 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.
Chronic inflammation is also referred to as slow, long-term inflammation lasting several months to years. Generally, the extent and effects of chronic inflammation vary with the cause of the injury and the ability of the body to repair and overcome the damage.
A CRP test result of more than 50 mg/dL is generally considered severe elevation. Results over 50 mg/L are associated with acute bacterial infections about 90% of the time.
Several things can cause chronic inflammation, including: untreated causes of acute inflammation, like an infection or injury. an autoimmune disorder, which involves your immune system mistakenly attacking healthy tissue. long-term exposure to irritants, like industrial chemicals or polluted air.
Over time, chronic inflammation can cause DNA damage and lead to cancer. For example, people with chronic inflammatory bowel diseases, such as ulcerative colitis and Crohn disease, have an increased risk of colon cancer.
Higher CRP levels have also been associated with the progression of skin, ovarian, and lung cancer. For this reason, CRP may be used to detect cancer recurrence after surgery [40].
Third, CRP is only one of the inflammatory markers, and a recent study has reported that genetically predicted circulating concentrations of several inflammatory-related cytokines were associated with the risk of breast, endometrial, lung, ovarian, and prostate cancer [39].
