Inflammation of the lymph nodes - when it comes to infection - Causes

Causes

The inflammatory process that may develop in the lymph nodes, may occur in acute and chronic forms. Acute process occurs with a pronounced clinical picture of the disease, in this case may require surgical intervention. Inflammation causes the lymph nodes in most cases are associated with exposure to various types of microorganisms.

Inflammation of the lymph nodes or lymphadenitis can be acute or chronic. Called pyogenic lymphadenitis different microorganisms (staphylococci, streptococci, and others), their toxins (poisons) and the decay products of tissues of the primary foci of purulent process.

The primary focus of infection may be an inflammation in any organ or tissue. The lymph nodes of microbes and their toxins enter through the lymphatic and blood vessels. It is also possible the penetration of microbes directly into a lymph node when it is injured. In such cases, lymphadenitis is the primary disease.

Moreover, there are specific lymphadenitis, which are caused by certain pathogens, such as the tubercle bacillus and occur strictly in accordance with this disease.

The most common reason

Causal factors for the development of lymphadenitis, there are several. In the first place there is the impact of the infection, the cause of this often leads to the development of the pathological process. The infection is caused by various pathogens:

• bacteria
• viruses
• mushrooms
• protozoa

Viral and bacterial infections are the actual cause of lymphadenitis. In pediatric practice faced with childhood infectious diseases, in which the units were among the first to respond to the penetration of the pathogen in the body. These infections include chickenpox, measles Measles in children - may cause serious complications , Scarlet fever and other diseases. Inflamed lymph nodes that group, which is anatomically closest to the source of infection. During the physical examination of a patient with colds or infectious disease, special attention should be paid to the inspection of the lymph nodes.

The lymphatic system is a kind of filter in the path of infection. The nodes increase in size and become inflamed as a result of a protective reaction. In the host microorganism is delayed, so on does not apply. When the inflammatory lesions regress, it is possible to observe a decrease in lymph node size, disappearance of the pathological symptoms.

In recent years, increased the role of infections that can be transmitted sexually (viral, chlamydial, mycoplasma infection), so when choosing the scope of anti-inflammatory therapy should always take into account the causative agent of lymphadenitis. Reason lymphadenitis urogenital infection due to exposure should be attributed to the specific nature of the inflammation.

In inflammation of lymph nodes, or lymphadenopathy, there are many reasons. In general, inflamed lymph nodes, where they are active, for example, due to infection, cancer, and certain other conditions.

Infection

This is the most common cause of swollen lymph nodes. Infections are bacterial, viral, parasitic and fungal.

Viral infections that cause swollen lymph nodes:

• Kissing disease
• Chickenpox
• Measles
• Herpes
• Colds
• Adenoviruses

Bacterial infections:

• Streptococcus
• Staphylococcus
• Cat scratch disease
• Tuberculosis
• Syphilis
• Chlamydia
• Other diseases, sexually transmitted infections

Vermin

• Toxoplasmosis
• Leishmaniasis

Inflammation

Among the inflammatory and immunological causes of inflammation of the lymph nodes diseases such as rheumatoid arthritis Arthritis - a variety of forms and complications , Lupus, hypersensitivity to certain drugs, and other violations.

Cancer

Different types of cancer can cause inflammation of the lymph nodes. This can be a cancer that develops in the lymph nodes or the blood cell - lymphoma and leukemia. This may also be the cancer spreads through the body from one body to another - metastatic cancer. For example, breast cancer can go to the nearest lymph nodes, which are located under the armpits, or lung cancer - to the lymph nodes Lymph nodes - what keeps our immune system Which are located near the collarbone.

Other reasons

Inflammation of the lymph nodes, in addition to the above, can also be caused by lipid metabolism disorders, sarcoidosis, graft rejection. Sometimes it is also associated with chronic fatigue syndrome Chronic fatigue - if life is not a pleasant experience   and other psychological problems.

What can have a negative impact

Inflammatory changes in the lymph nodes can be associated with systemic diseases. Immunological reason is related to the formation of immune complexes in the blood that cause systemic changes in the body as a whole. Inflammation of the lymph nodes can be detected in rheumatoid arthritis, systemic lupus erythematosus, various autoimmune diseases. In autoimmune processes observed discoloration of the skin (hemorrhagic syndrome, petechial rash), joint damage, temperature reaction, deterioration of the general state of health. These symptoms help during diagnostic procedures.

This reaction on the part of the lymphatic system should be considered protective of the body in contact with the allergen. As an advocate of a pathological agent of various substances, so if you suspect an allergic nature of the disease is recommended for a complete examination to determine that acts as the primary causative factor.

Allergy occurs with characteristic clinical symptoms - runny nose, coughing, watery eyes, sneezing, swelling. The lymphatic system tries to rid the body of the pathological agent that causes the phenomenon of allergies, so swollen lymph nodes can be called a natural consequence. After the elimination of the allergen from the body observed regression of symptoms, changes in the lymph nodes eventually pass.

All of these reasons are secondary. If there is a traumatic injury site with the development of inflammation in it, this will be the primary reason. It is necessary to take into account the accession of the risk of infection during the injury.
