Understanding Lymph Nodes: Their Function and Importance

Lymph nodes are small, round structures that play a crucial role in the body’s immune system. These tiny powerhouses are responsible for filtering fluids, trapping harmful substances, and housing immune cells that fight off infections. But what exactly happens when these nodes become swollen?

Swollen lymph nodes, also known as swollen glands, are often a sign that your body is working hard to combat an infection or other health issue. They can be found in various parts of the body, including under the jaw, on each side of the neck, under the armpits, and on either side of the groin.

How do lymph nodes function?

Lymph nodes act as filters for lymph fluid, which flows throughout the body. This fluid collects waste materials, harmful germs, and other potentially dangerous substances. As the fluid passes through the lymph nodes, these unwanted elements are trapped and dealt with by immune cells. The filtered fluid is then released back into the bloodstream, along with essential salts and proteins.

Common Causes of Swollen Lymph Nodes

Swollen lymph nodes can be caused by a variety of factors, ranging from common infections to more serious medical conditions. Understanding these causes can help you determine when to seek medical attention.

Viral Infections

The most common cause of swollen lymph nodes is viral infections. These include:

• Common cold
• Influenza (flu)
• Sinus infections
• Mononucleosis
• Tonsillitis
• Herpes

Bacterial Infections

Bacterial infections can also lead to swollen lymph nodes. Some examples are:

• Strep throat
• Tooth or gum infections
• Skin infections
• Tuberculosis

Immune System Disorders

In some cases, swollen lymph nodes may be a sign of an underlying immune system disorder. These can include:

• Systemic lupus erythematosus (lupus)
• Rheumatoid arthritis
• Sjogren’s syndrome

Cancer

While less common, swollen lymph nodes can sometimes indicate the presence of cancer. Types of cancer that may cause lymph node swelling include:

• Lymphoma
• Hodgkin’s disease
• Leukemia
• Metastatic cancer

Recognizing Swollen Lymph Nodes: Signs and Symptoms

Identifying swollen lymph nodes is an important step in determining whether you need to seek medical attention. But how can you tell if your lymph nodes are swollen?

Physical characteristics of swollen lymph nodes

Swollen lymph nodes typically feel like soft, round bumps under the skin. They may be as small as a pea or as large as a grape. When touched, they might feel tender, which is a sign of inflammation. In some cases, the affected lymph nodes may appear visibly larger than normal.

Comparing lymph nodes

Since lymph nodes appear in pairs on both sides of the body, you can compare them to check for swelling. If one side feels larger than the other, it’s likely that the larger one is swollen.

Associated symptoms

Swollen lymph nodes often come with other symptoms, depending on the underlying cause. These may include:

• Sore throat
• Fever
• Fatigue
• Night sweats
• Unexplained weight loss (in more serious cases)

Diagnosing Swollen Lymph Nodes: When to See a Doctor

While many cases of swollen lymph nodes resolve on their own, there are times when medical attention is necessary. But when should you consult a healthcare professional?

Duration of swelling

If your lymph nodes remain swollen for more than two weeks without any obvious cause, it’s time to see a doctor. Persistent swelling could indicate a more serious underlying condition that requires medical attention.

Size and texture

Lymph nodes that are larger than 1 inch (2.5 cm) in diameter or feel hard, rubbery, and fixed in place should be evaluated by a healthcare professional. These characteristics could be signs of a more serious condition, such as cancer.

Accompanying symptoms

If you experience any of the following symptoms along with swollen lymph nodes, seek medical attention:

• Unexplained fever
• Night sweats
• Unexplained weight loss
• Difficulty breathing or swallowing
• Redness or warmth around the swollen area

Diagnostic Procedures for Swollen Lymph Nodes

When you visit a doctor for swollen lymph nodes, they may perform several diagnostic procedures to determine the underlying cause. What are these procedures, and what can you expect during your visit?

Physical examination

The doctor will likely start with a thorough physical examination. They will feel the affected lymph nodes to assess their size, texture, and tenderness. They may also check other areas of your body for additional swollen nodes.

Medical history

Your doctor will ask about your medical history, recent illnesses, and any other symptoms you’ve been experiencing. This information can help narrow down potential causes of your swollen lymph nodes.

Blood tests

Blood tests may be ordered to check for signs of infection, inflammation, or other abnormalities. These tests can help identify specific conditions such as mononucleosis or HIV.

Imaging tests

In some cases, imaging tests may be necessary to get a better look at the affected lymph nodes and surrounding tissues. These may include:

• X-rays
• Ultrasound
• CT scans
• MRI scans

Biopsy

If other tests are inconclusive or if cancer is suspected, your doctor may recommend a biopsy. This involves removing a small sample of tissue from the affected lymph node for laboratory analysis.

Treatment Options for Swollen Lymph Nodes

The treatment for swollen lymph nodes depends on the underlying cause. In many cases, the swelling will resolve on its own as the body fights off the infection. However, there are several treatment options available for more persistent or serious cases.

Self-care measures

For mild cases of swollen lymph nodes caused by common infections, self-care measures may be sufficient. These can include:

• Rest and hydration
• Over-the-counter pain relievers like ibuprofen or acetaminophen
• Warm compresses applied to the affected area

Antibiotics

If a bacterial infection is the cause of your swollen lymph nodes, your doctor may prescribe antibiotics. It’s important to take the full course of antibiotics as prescribed, even if you start feeling better before finishing the medication.

Antiviral medications

For certain viral infections, such as severe cases of herpes or HIV, antiviral medications may be prescribed to help manage the condition and reduce lymph node swelling.

Treatment for underlying conditions

If your swollen lymph nodes are caused by an underlying medical condition, such as an autoimmune disorder or cancer, treatment will focus on addressing that specific condition. This may involve:

• Immunosuppressive drugs for autoimmune disorders
• Chemotherapy or radiation therapy for cancer
• Targeted therapies for specific types of cancer

Preventing Swollen Lymph Nodes: Tips for Maintaining a Healthy Immune System

While it’s not always possible to prevent swollen lymph nodes, there are steps you can take to support your immune system and reduce your risk of infections that can cause lymph node swelling. What are some effective ways to maintain a healthy immune system?

Healthy lifestyle habits

Adopting healthy lifestyle habits can go a long way in supporting your immune system. Some key practices include:

• Getting adequate sleep (7-9 hours per night for adults)
• Exercising regularly
• Eating a balanced diet rich in fruits, vegetables, and whole grains
• Managing stress through relaxation techniques or mindfulness practices

Proper hygiene

Good hygiene practices can help prevent infections that may lead to swollen lymph nodes. These include:

• Washing hands frequently with soap and water
• Avoiding close contact with people who are sick
• Covering your mouth and nose when coughing or sneezing
• Keeping wounds clean and covered

Vaccinations

Staying up-to-date on recommended vaccinations can help prevent various infections that may cause lymph node swelling. Consult with your healthcare provider to ensure you’re current on all necessary immunizations.

Living with Swollen Lymph Nodes: Coping Strategies and Long-Term Outlook

Dealing with swollen lymph nodes can be uncomfortable and sometimes concerning. How can you cope with the symptoms, and what can you expect in terms of long-term outlook?

Managing discomfort

To alleviate discomfort associated with swollen lymph nodes, you can try the following:

• Apply warm compresses to the affected area
• Take over-the-counter pain relievers as needed
• Wear loose-fitting clothing to avoid irritation
• Get plenty of rest to support your body’s healing process

Monitoring your condition

Keep track of your symptoms and any changes in the size or texture of your lymph nodes. If you notice any concerning changes or if your symptoms persist, don’t hesitate to follow up with your healthcare provider.

Long-term outlook

The long-term outlook for swollen lymph nodes depends on the underlying cause. In most cases, swollen lymph nodes due to common infections will resolve on their own within a few weeks. For more serious conditions, such as autoimmune disorders or cancer, ongoing treatment and monitoring may be necessary.

Remember that swollen lymph nodes are often a sign that your body is working hard to fight off an infection or other health issue. By staying vigilant, maintaining good health practices, and seeking medical attention when necessary, you can effectively manage swollen lymph nodes and support your overall well-being.

Swollen lymph nodes: Causes, diagnosis, and treatment

Swollen lymph nodes usually indicate a common infection, but they can also signal a medical condition, such as an immune disorder or, rarely, a type of cancer.

Lymph nodes are small, round structures that play a vital role in the body’s immune system. Swollen lymph nodes are also known as swollen glands.

In this article, we look at the causes of swollen lymph nodes, when to see a doctor, and treatment options.

The lymph nodes collect and filter fluids, waste materials, and harmful germs. The human body has hundreds of lymph nodes. The main lymph nodes that people may see or feel are found:

• under the jaw
• on each side of the neck
• under the armpits
• on either side of the groin

Lymph fluid flows in and out of the lymph nodes throughout the body before finally making its way back to the chest. While doing so, it collects and traps harmful matter, such as bacteria, viruses, and bodily waste products. The lymph nodes filter the fluid and release it back into the bloodstream together with salts and proteins.

Lymph nodes also contain immune cells that help fight infection by attacking the germs that the body’s lymph fluid has collected.

The lymph nodes may swell when a person has a temporary infection. The swelling occurs as a result of immune cell activity in the lymph nodes.

The location of the swelling often relates to the affected area. For example, an ear infection may cause swollen lymph nodes near the ear, while someone with an upper respiratory tract infection may notice swollen lymph nodes in their neck.

People can check whether their lymph nodes are swollen by gently pressing around the area, such as the side of the neck.

Swollen lymph nodes will feel like soft, round bumps, and they may be the size of a pea or a grape. They might be tender to the touch, which indicates inflammation. In some cases, the lymph nodes will also look larger than usual.

Lymph nodes appear in parallel on both sides of the body. People can check the nodes on each side and compare them to see if one is larger than the other, which is likely to indicate swelling.

Many people with swollen glands also experience pain while making sudden or strained movements. Such movements include sharply turning the neck, bobbing the head, or eating foods that are difficult to chew.

Swollen lymph nodes often occur alongside other symptoms. These vary depending on the underlying problem but may include a sore throat, cough, or flu-like symptoms.

Many different conditions cause the lymph nodes to swell, particularly the nodes in the head and neck. These conditions include autoimmune disorders, specific types of cancer, and common infections, such as the flu. Certain medications, such as antimalarials and antiseizure drugs, can also cause swelling.

Most people have localized lymphadenopathy, in which only the lymph nodes in one particular area of the body swell up. When more than one region swells, this is called generalized lymphadenopathy, and it usually signifies a systemic, or body-wide, disease that may require medical attention.

In the following sections, we discuss the possible causes of swollen lymph nodes in more detail.

Infections

The infections that can cause swollen lymph nodes are mostly viral. Common infections include:

• the common cold
• the flu
• sinus infections
• mononucleosis
• tonsillitis
• tooth or gum infections
• staph infections
• strep throat
• skin infections
• fungal infections

More severe infections that can cause swelling in one or multiple lymph node areas include:

• chicken pox
• tuberculosis
• measles
• rubella
• herpes
• Lyme disease
• HIV
• toxoplasmosis

Cat scratch fever, which is also called cat scratch disease, can cause localized lymph node swelling in the area near the cat scratch.

Immune system disorders

Immune disorders that can cause swollen lymph glands include:

• systemic lupus erythematosus (lupus)
• rheumatoid arthritis
• Sjogren’s syndrome

Cancers

Much less commonly, swollen lymph nodes can also indicate a malignancy, or cancer, including:

• lymphoma
• Hodgkin disease
• leukemia
• metastases, or the spread of an existing cancer
• Kaposi sarcoma

Certain risk factors make a person more likely to have a malignant lymph problem, such as lymphoma. These include:

• being aged 40 years or older
• being male
• having white skin

People with a malignant lymph node may notice that the node feels hard or rubbery. They may also experience systemic symptoms, such as fever, night sweats, and unexplained weight loss.

Swelling in the groin lymph nodes

Sexually transmitted infections (STIs), such as syphilis and gonorrhea, can cause swollen lymph nodes, typically in the groin area. Lymph nodes in the groin are also known as inguinal lymph nodes.

Recurring infections, lower body infections, and injury to the legs can also cause swollen lymph nodes in the groin.

In many cases, swelling reduces and then disappears within 2 to 3 weeks once the body has successfully fought the infection. If the problem persists for longer than a couple of weeks, it might warrant a visit to the doctor.

Other reasons to visit the doctor include:

• a lymph node that feels hard or rubbery to the touch
• a node that does not move freely
• a node that is an inch or more in diameter
• swollen lymph nodes that accompany night sweats, abdominal pain, unexplained weight loss, or a high fever

A doctor can often diagnose the cause of swollen lymph nodes by carrying out a physical examination with a focus on the affected area and by discussing the person’s symptoms and medical history.

However, they may also order medical tests to determine the cause of the swelling. These tests may include a routine blood test to look for signs of infection.

Imaging tests can help a doctor look closely at the lymph nodes and the surrounding structures of the body. Imaging tests include:

• ultrasound
• CT scan
• MRI scan

If the swelling continues for several weeks or a person has other warning signs, a doctor may recommend a lymph node biopsy. During this procedure, the doctor will numb the area, make a small cut, and remove a section of lymph node tissue to send to a laboratory for examination under a microscope.

Alternatively, they may opt for fine needle aspiration, which involves using a needle to remove some cells from the lymph node for analysis.

Share on PinterestDrinking plenty of fluids will help reduce symptoms that an infection may cause.

Lymph node swelling will usually disappear once the infection clears. The swelling may also go away when the person takes prescribed medications, such as antibiotics or antivirals.

Doctors may prescribe anti-inflammatory medication if a person has tissue swelling.

If an underlying medical condition is responsible for the lymph nodes swelling, treating this condition should reduce the swelling.

Common home remedies to treat the symptoms of swollen lymph nodes include:

• taking over-the-counter pain medicines, such as acetaminophen or ibuprofen
• applying a warm wet compress to the affected area
• drinking plenty of fluids, such as water and fresh juices
• resting to help the body recover from the illness

Swollen lymph nodes are usually a symptom of another condition, such as an infection, and they tend to resolve on their own within several weeks.

It is best to consult a doctor if swollen lymph nodes persist for longer than 3 weeks or occur alongside other symptoms, such as high fever, abdominal pain, or night sweats. The cause of the swelling will determine the treatment.

What is inflammation of the lymph nodes?

The lymphatic system ensures the normal functioning of the immune system, internal organs and tissues. One of the most common diseases of the lymphatic system is lymphadenitis of the lymph nodes. The disease has a different etiology, symptoms and degree of danger to health. In the article we will talk about how to recognize the pathology and what methods of treatment exist.

What is the lymphatic system

The lymphatic system is a network of lymphatic vessels and nodes. These vessels transport a special liquid – lymph. It is responsible for the transport of proteins, salts and metabolites into the blood.

Lymph nodes act as a filter. They purify the lymph from pathogenic microorganisms and foreign substances, due to which purified and safe lymphatic fluid enters the bloodstream. Source:
The role of lymph nodes in human life. Okunyaka O.M., Tumasyan T.I. Bulletin of science. 2019. №3. pp.60-62.

The lymphatic system performs three main functions:

1. Participates in immune defense. Together with the flow of lymph, pathogenic microorganisms enter the lymph nodes, where they are recognized and destroyed.
2. Maintains proper fluid levels in tissues. With an excessive amount of fluid, the lymphatic vessels “drain” organs and tissues.
3. Produces fat metabolism. Lymphatic vessels transport lipids, which are involved in almost all metabolic processes.

Functions of the lymph nodes

There are about 500 lymph nodes in the human body. They play the role of a barrier and a pump and perform several important functions:

• Hematopoietic. Lymph nodes are involved in the development of white blood cells – lymphocytes. Lymphocytes are cells of the immune system responsible for fighting various infections and diseases.
• Drainage, or transport. Lymph nodes play an important role in the transport of lymph, which enters the lymphatic vessels from the intercellular spaces of tissues. Due to this, exudate and metabolic products are utilized from the tissues.
• Barrier. Lymph nodes serve as a barrier to infected cells and microorganisms, preventing them from spreading throughout the body. They can also form antibodies that help neutralize and destroy infectious agents.

What is lymphadenitis

Lymphadenitis is an inflammation of the lymph nodes. In most cases, this is not an independent disease, but a complication of the primary pathology. It is most often a sign of a bacterial, viral, fungal, or protozoal infection. Source:
Lymphadenopathy. Melikyan A.L., Egorova E.K., Kovrigina A.M. Clinical guidelines. 2018. p.5-30. Therefore, to find the cause of the inflammatory process, complex diagnostics are needed.

Depending on the etiology, one or more lymph nodes may become inflamed. With lymphadenitis, the following types of lymph nodes are usually affected:

• cervical;
• elbow;
• submandibular;
• popliteal;
• inguinal;
• axillary.

In lymphadenitis, the lymph node becomes enlarged and painful. This is due to an increase in the number of lymphocytes and other cells of the immune system that collect inside it. If an infectious agent has entered the lymph node and caused the formation of an abscess or abscess, purulent inflammation may develop.

In the absence of timely treatment, lymphadenitis provokes the development of dangerous complications: the spread of infection to other tissues and organs, the formation of fistulas, sepsis. Therefore, it is important to consult a doctor at the first sign of illness.

Causes

Most common causes:

• Infections. In most cases, inflammation in the area of ​​the lymph node occurs precisely against the background of infection: tonsillitis, scarlet fever, stomatitis, SARS, influenza, tuberculosis, brucellosis, chicken pox, etc.
• Injuries and operations. Any injury, surgery and other damage to the lymph node can cause inflammation.
• Allergic reactions. Some allergens activate a cascade of inflammatory responses.
• Oncological diseases. Lymphadenitis sometimes becomes one of the signs of malignant tumors of the lymphatic system, especially lymphoma.
• Autoimmune diseases. Lymph node inflammation can accompany systemic lupus erythematosus and rheumatoid arthritis.

In some cases, it is not possible to determine the etiology of inflammation of the lymph node. Then a diagnosis of “lymphadenitis, unspecified” is established.

Clinical recommendations of the Ministry of Health of the Russian Federation offer several classifications of lymphadenitis.

Origin:

• Primary. Occurs when an infection or other cause of inflammation occurs directly in the lymph node. This most commonly occurs when bacteria or other pathogens enter the body through a skin wound, or when certain viruses, such as the Epstein-Barr virus, infect the lymphatic system.
• Secondary. Occurs when an infection or other cause of inflammation is localized not in the lymph node itself, but elsewhere in the body. In this case, the inflammatory process spreads from the primary focus to the lymph nodes through the lymphatic vessels. For example, secondary lymphadenitis can occur with an infection of the pharynx or teeth, as well as in the presence of cancer or blood diseases.

Intensity and duration of inflammation:

• Acute. It is characterized by an abrupt onset, rapid progression, and an acute inflammatory response. Usually acute lymphadenitis is accompanied by pain, swelling, redness of the skin, fever and other signs of inflammation. Source:
  Treatment of chronic tonsillitis and acute lymphadenitis. Pavlova K.V. Medicines and rational pharmacotherapy. 2022. No. 5-2. pp. 90-91.
• Chronic. It is characterized by a sluggish long course and a low intensity of the inflammatory process. Most often it develops against the background of untreated acute lymphadenitis. The chronic form is characterized by two periods: exacerbation and remission. In the first case, clinical manifestations are pronounced, in the second – weakly or completely absent, an imaginary recovery occurs.
• Recurrent. It is characterized by periodic exacerbations of inflammation after a temporary improvement. Usually, relapses occur in the presence of a chronic infectious or inflammatory process in the body.

By the nature of inflammation:

• Purulent. It is characterized by the formation of pus inside the lymph node. It occurs as a result of an infection caused by bacteria, fungi, or other microorganisms. As a rule, purulent lymphadenitis is accompanied by severe pain, swelling, redness of the skin and fever.
• Serous. It differs in the formation of serous fluid inside the affected lymph node, and the inflammatory process does not go beyond its capsule. Often found in children.

Localization:

• submandibular – usually occurs against the background of diseases of the oral cavity, teeth or pharynx;
• axillary – associated with infectious or oncological diseases of the breast;
• inguinal – occurs against the background of skin infections and skin lesions;
• cervical – develops when the pharynx, mouth, nose or ears are affected. Source:

• parotid – caused by infectious diseases of the ear or mouth;
• occipital – occurs against the background of pathologies of the skin or upper respiratory tract.

Symptoms

Symptoms of lymphadenitis depend on its type, location and cause. The most common signs of inflammation of the lymph node:

• swelling and tenderness of the affected lymph node;
• redness of the skin in the affected area;
• general weakness, fatigue and fever;
• pain and discomfort when touching an affected lymph node;
• headache;
• sometimes – nausea, vomiting and loss of appetite;
• excessive sweating, especially at night;
• change in color and texture of the skin in the area of ​​an inflamed lymph node;
• appearance of spots on the skin or other rashes.

Ways of infection

The primary cause of secondary lymphadenitis can be:

• trophic ulcer;
• caries;
• otitis;
• influenza;
• tonsillitis;
• angina;
• herpes;
• tumor;
• tuberculosis and more.

Lymphadenitis sometimes develops due to skin lesions such as scratches, wounds, or insect bites, which can become entry gates for bacteria.

Possible complications

Many people don’t even realize the danger of lymphadenitis. Without timely treatment, the disease leads to various, including dangerous consequences. Most often, the following complications develop:

• abscess – a limited accumulation of pus in the tissues, surrounded by a membrane;
• sepsis is a severe infectious disease in which the infection spreads throughout the body through the bloodstream;
• compression of surrounding tissues – enlarged lymph nodes cause discomfort and put pressure on neighboring tissues;
• thrombophlebitis – inflammation of the venous wall with the formation of blood clots that can clog the lumen of the vein;
• fistula – the formation of a pathological channel as a result of the accumulation of purulent fluid.

When to see a doctor

Lymphadenitis is diagnosed and treated by a vascular surgeon. It is necessary to consult a doctor at the first signs of the disease. The specialist will prescribe a diagnosis to identify the cause of inflammation and tell the patient what to do. Timely access to a doctor prevents the development of dangerous complications.

Diagnosis

Diagnosis of lymphadenitis is aimed at finding the cause of the inflammatory process, assessing the current state of the lymph node and the body as a whole. For this, a comprehensive examination is used:

• Inspection. The doctor examines the skin at the site of the affected lymph node, evaluates its size, shape, texture, temperature and sensitivity of the skin.
• General and biochemical blood test. Analyzes confirm the inflammatory and infectious process.
• Biopsy. Taking a sample of a lymph node for histological examination allows you to determine the cellular composition of the tissue and differentiate the tumor. Source:
  Differential diagnosis of bacterial and viral lymphadenitis in children. Antonova S.S., Botvin’eva V.V., Sitnikov I.G. VSP. 2008. No. 3. pp.76-78.
• ultrasound. Ultrasound examination helps to determine the size and structure of the lymph node, as well as to identify the neoplasm.
• CT and MRI. The procedures are used for layer-by-layer study of the lymph node and surrounding soft tissues.
• Culture study. If lymphadenitis is caused by a bacterial infection, a bacterial culture is performed to determine the type of bacteria and select the most effective antibiotic.

Methods of treatment

The doctor chooses the method of treatment individually for each clinical case. It depends on the etiology of inflammation, the current state of the patient and associated complications. In most cases, conservative therapy is used, including medication, including:

• antibiotics if there is a bacterial infection;
• antiviral drugs – in the presence of a viral infection;
• antifungals – in the presence of a fungal infection;
• non-steroidal anti-inflammatory drugs – for the relief of inflammation and pain.

In addition, physiotherapy, compresses and massage are used. In the presence of abscesses, surgical intervention is indicated – removal of purulent contents and sanitation of the affected tissues.

Forecast and prevention of the disease

With timely visit to the doctor, lymphadenitis of the lymph node has a favorable prognosis. Early initiation of treatment allows you to achieve complete recovery, prevent the development of complications and the transition of the disease to a chronic form.

Due to the lack of a single etiology, there is no specific prevention of lymphadenitis. The following recommendations will help prevent infection:

• Maintain good personal hygiene. Wash your hands regularly with soap and water, especially after handling animals and visiting public places.
• Minimize contact with infected patients and visits to crowded places. If there is a sick person in the family, it is necessary to limit contact with him.
• Using only your own hygiene items. Do not use other people’s towels, razors, toothbrushes, etc.
• Strengthening immunity: giving up bad habits, maintaining physical activity, proper nutrition and regular walks in the fresh air.
• Timely treatment of diseases. When the first symptoms appear, you should immediately consult a doctor and do not self-medicate.
• Vaccination. Timely vaccination helps prevent infections that can cause lymphadenitis. You need to be vaccinated both in childhood and in adulthood.

What is inflammation of the lymph nodes?

The lymphatic system ensures the normal functioning of the immune system, internal organs and tissues. One of the most common diseases of the lymphatic system is lymphadenitis of the lymph nodes. The disease has a different etiology, symptoms and degree of danger to health. In the article we will talk about how to recognize the pathology and what methods of treatment exist.

What is the lymphatic system

The lymphatic system is a network of lymphatic vessels and nodes. These vessels transport a special liquid – lymph. It is responsible for the transport of proteins, salts and metabolites into the blood.

Lymph nodes act as a filter. They purify the lymph from pathogenic microorganisms and foreign substances, due to which purified and safe lymphatic fluid enters the bloodstream. Source:
The role of lymph nodes in human life. Okunyaka O.M., Tumasyan T.I. Bulletin of science. 2019. No. 3. pp.60-62.

The lymphatic system performs three main functions:

1. Participates in immune defense. Together with the flow of lymph, pathogenic microorganisms enter the lymph nodes, where they are recognized and destroyed.
2. Maintains proper fluid levels in tissues. With an excessive amount of fluid, the lymphatic vessels “drain” organs and tissues.
3. Produces fat metabolism. Lymphatic vessels transport lipids, which are involved in almost all metabolic processes.

Functions of the lymph nodes

There are about 500 lymph nodes in the human body. They play the role of a barrier and a pump, perform several important functions:

• Hematopoietic. Lymph nodes are involved in the development of white blood cells – lymphocytes. Lymphocytes are cells of the immune system responsible for fighting various infections and diseases.
• Drainage, or transport. Lymph nodes play an important role in the transport of lymph, which enters the lymphatic vessels from the intercellular spaces of tissues. Due to this, exudate and metabolic products are utilized from the tissues.
• Barrier. Lymph nodes serve as a barrier to infected cells and microorganisms, preventing them from spreading throughout the body. They can also form antibodies that help neutralize and destroy infectious agents.

What is lymphadenitis

Lymphadenitis is an inflammation of the lymph nodes. In most cases, this is not an independent disease, but a complication of the primary pathology. It is most often a sign of a bacterial, viral, fungal, or protozoal infection. Source:
Lymphadenopathy. Melikyan A.L., Egorova E.K., Kovrigina A.M. Clinical guidelines. 2018. p.5-30. Therefore, to find the cause of the inflammatory process, complex diagnostics are needed.

Depending on the etiology, one or more lymph nodes may become inflamed. With lymphadenitis, the following types of lymph nodes are usually affected:

• cervical;
• elbow;
• submandibular;
• popliteal;
• inguinal;
• axillary.

In lymphadenitis, the lymph node becomes enlarged and painful. This is due to an increase in the number of lymphocytes and other cells of the immune system that collect inside it. If an infectious agent has entered the lymph node and caused the formation of an abscess or abscess, purulent inflammation may develop.

In the absence of timely treatment, lymphadenitis provokes the development of dangerous complications: the spread of infection to other tissues and organs, the formation of fistulas, sepsis. Therefore, it is important to consult a doctor at the first sign of illness.

Causes

Most common causes:

• Infections. In most cases, inflammation in the area of ​​the lymph node occurs precisely against the background of infection: tonsillitis, scarlet fever, stomatitis, SARS, influenza, tuberculosis, brucellosis, chicken pox, etc.
• Injuries and operations. Any injury, surgery and other damage to the lymph node can cause inflammation.
• Allergic reactions. Some allergens activate a cascade of inflammatory responses.
• Oncological diseases. Lymphadenitis sometimes becomes one of the signs of malignant tumors of the lymphatic system, especially lymphoma.
• Autoimmune diseases. Lymph node inflammation can accompany systemic lupus erythematosus and rheumatoid arthritis.

In some cases, it is not possible to determine the etiology of inflammation of the lymph node. Then a diagnosis of “lymphadenitis, unspecified” is established.

Clinical recommendations of the Ministry of Health of the Russian Federation offer several classifications of lymphadenitis.

Origin:

• Primary. Occurs when an infection or other cause of inflammation occurs directly in the lymph node. This most commonly occurs when bacteria or other pathogens enter the body through a skin wound, or when certain viruses, such as the Epstein-Barr virus, infect the lymphatic system.
• Secondary. Occurs when an infection or other cause of inflammation is localized not in the lymph node itself, but elsewhere in the body. In this case, the inflammatory process spreads from the primary focus to the lymph nodes through the lymphatic vessels. For example, secondary lymphadenitis can occur with an infection of the pharynx or teeth, as well as in the presence of cancer or blood diseases.

Intensity and duration of inflammation:

• Acute. It is characterized by an abrupt onset, rapid progression, and an acute inflammatory response. Usually acute lymphadenitis is accompanied by pain, swelling, redness of the skin, fever and other signs of inflammation Source:
  Treatment of chronic tonsillitis and acute lymphadenitis. Pavlova K.V. Medicines and rational pharmacotherapy. 2022. No. 5-2. pp. 90-91.
• Chronic. It is characterized by a sluggish long course and a low intensity of the inflammatory process. Most often it develops against the background of untreated acute lymphadenitis. The chronic form is characterized by two periods: exacerbation and remission. In the first case, clinical manifestations are pronounced, in the second – weakly or completely absent, an imaginary recovery occurs.
• Recurrent. It is characterized by periodic exacerbations of inflammation after a temporary improvement. Usually, relapses occur in the presence of a chronic infectious or inflammatory process in the body.

By the nature of inflammation:

• Purulent. It is characterized by the formation of pus inside the lymph node. It occurs as a result of an infection caused by bacteria, fungi, or other microorganisms. As a rule, purulent lymphadenitis is accompanied by severe pain, swelling, redness of the skin and fever.
• Serous. It differs in the formation of serous fluid inside the affected lymph node, and the inflammatory process does not go beyond its capsule. Often found in children.

Localization:

• submandibular – usually occurs against the background of diseases of the oral cavity, teeth or pharynx;
• axillary – associated with infectious or oncological diseases of the breast;
• inguinal – occurs against the background of skin infections and skin lesions;
• cervical – develops when the pharynx, mouth, nose or ears are affected. Source:

• parotid – caused by infectious diseases of the ear or mouth;
• occipital – occurs against the background of pathologies of the skin or upper respiratory tract.

Symptoms

Symptoms of lymphadenitis depend on its type, location and cause. The most common signs of inflammation of the lymph node:

• swelling and soreness of the affected lymph node;
• redness of the skin in the affected area;
• general weakness, fatigue and fever;
• pain and discomfort when touching an affected lymph node;
• headache;
• sometimes – nausea, vomiting and loss of appetite;
• excessive sweating, especially at night;
• change in color and texture of the skin in the area of ​​an inflamed lymph node;
• appearance of spots on the skin or other rashes.

Routes of infection

The primary cause of secondary lymphadenitis may be:

• trophic ulcer;
• caries;
• otitis;
• influenza;
• tonsillitis;
• angina;
• herpes;
• tumor;
• tuberculosis and more.

Lymphadenitis sometimes develops due to skin lesions such as scratches, wounds, or insect bites, which can become entry gates for bacteria.

Possible complications

Many people don’t even realize the danger of lymphadenitis. Without timely treatment, the disease leads to various, including dangerous consequences. Most often, the following complications develop:

• abscess – a limited accumulation of pus in the tissues, surrounded by a membrane;
• sepsis is a severe infectious disease in which the infection spreads throughout the body through the bloodstream;
• compression of surrounding tissues – enlarged lymph nodes cause discomfort and put pressure on neighboring tissues;
• thrombophlebitis – inflammation of the venous wall with the formation of blood clots that can clog the lumen of the vein;
• fistula – the formation of a pathological channel as a result of the accumulation of purulent fluid.

When to see a doctor

Lymphadenitis is diagnosed and treated by a vascular surgeon. It is necessary to consult a doctor at the first signs of the disease. The specialist will prescribe a diagnosis to identify the cause of inflammation and tell the patient what to do. Timely access to a doctor prevents the development of dangerous complications.

Diagnosis

Diagnosis of lymphadenitis is aimed at finding the cause of the inflammatory process, assessing the current state of the lymph node and the body as a whole. For this, a comprehensive examination is used:

• Inspection. The doctor examines the skin at the site of the affected lymph node, evaluates its size, shape, texture, temperature and sensitivity of the skin.
• General and biochemical blood test. Analyzes confirm the inflammatory and infectious process.
• Biopsy. Taking a sample of a lymph node for histological examination allows you to determine the cellular composition of the tissue and differentiate the tumor. Source:
  Differential diagnosis of bacterial and viral lymphadenitis in children. Antonova S.S., Botvin’eva V.V., Sitnikov I.G. VSP. 2008. No. 3. pp.76-78.
• ultrasound. Ultrasound examination helps to determine the size and structure of the lymph node, as well as to identify the neoplasm.
• CT and MRI. The procedures are used for layer-by-layer study of the lymph node and surrounding soft tissues.
• Culture study. If lymphadenitis is caused by a bacterial infection, a bacterial culture is performed to determine the type of bacteria and select the most effective antibiotic.

Methods of treatment

The doctor chooses the method of treatment individually for each clinical case. It depends on the etiology of inflammation, the current state of the patient and associated complications. In most cases, conservative therapy is used, including medication, including:

• antibiotics if there is a bacterial infection;
• antiviral drugs – in the presence of a viral infection;
• antifungals – in the presence of a fungal infection;
• non-steroidal anti-inflammatory drugs – for the relief of inflammation and pain.

In addition, physiotherapy, compresses and massage are used. In the presence of abscesses, surgical intervention is indicated – removal of purulent contents and sanitation of the affected tissues.

Forecast and prevention of the disease

With timely visit to the doctor, lymphadenitis of the lymph node has a favorable prognosis. Early initiation of treatment allows you to achieve complete recovery, prevent the development of complications and the transition of the disease to a chronic form.
