What is a chronic inflammatory disease?

A chronic inflammatory disease is a medical condition characterized by persistent inflammation. Several diseases fall into this category, and a great deal of research has been done to learn more about such diseases and how they work. In many cases, a genetic component has been identified that may put people at risk of developing particular chronic inflammatory diseases, and in some cases, multiple genes may be involved.

Patients develop a chronic inflammatory disease because the immune system has an inappropriate response to something it has been exposed to. In some cases, this means that the patient develops an autoimmune disease, in which the immune system begins to attack the body because it has become confused. In other cases, the patient experiences chronic inflammation in response to certain foods or environmental factors such as smoke. The inflammation may wax and wane but remains persistent and often resists treatment.

Chronic inflammation can cause considerable damage to the body's tissues, and can lead to a variety of problems, depending on where it is located. Some researchers, for example, have found that chronic inflammatory disease in the liver and digestive tract can cause changes in the brain that lead to fatigue and personality changes. These diseases can also interfere with the function of various organs, and in many cases, the inflammation can spread throughout the body.

Some examples of chronic inflammatory diseases include: celiac disease, vasculitis, lupus, chronic obstructive pulmonary disease (COPD), irritable bowel disease, atherosclerosis, arthritis, and psoriasis. Some of these conditions have a clear genetic component that can be used to identify patients with congenital cases, and in other cases, certain genes may increase the risk of developing such conditions. In other cases, the onset is apparently random or caused by lifestyle choices made by the patient.

People with chronic inflammatory diseases tend to suffer a lot. Because the inflammation often cannot be fully controlled, the patient is constantly on medication and may experience pain, fatigue, digestive problems, and other symptoms caused by the inflammation and medication side effects. Some people also find that their symptoms and struggles are dismissed by people like employers and co-workers, who may not fully understand the processes and debilitation that may be involved in chronic inflammatory disease.

Researchers are looking for new ways to prevent and treat such conditions, and many patients may be eligible for clinical trials testing various treatment approaches. Participating in such trials can benefit patients as individuals and science in general by adding useful information to the field of knowledge about chronic inflammatory disease.
