Infectious arthritis signs, causes and treatment methods

Arthritis is one of the most common health problems that cause severe pain and make movement difficult, affecting the ability to carry out daily activities normally. One of the most dangerous types of arthritis is septic arthritis, which can affect some people without them having enough knowledge about it, making it difficult for them to deal with it properly. That’s why, in Dalili Medical, we will discuss this type of arthritis in detail, exploring its main causes, symptoms, and the different treatment options available.

What’s the Difference Between Septic Arthritis and Reactive Arthritis?

Both conditions have similar symptoms, but the difference lies in the cause. Septic arthritis occurs due to a direct infection in the joint itself, usually caused by bacteria, viruses, or fungi. This infection often comes from a wound, surgery, or an infection in the bloodstream. On the other hand, reactive arthritis happens after the body has been exposed to an infection in another part of the body, such as a gastrointestinal infection (like food poisoning) or a sexually transmitted infection.

1. What Are the Causes of Septic Arthritis?

The main cause is an infection entering the joint, which can happen due to an injury, surgery, or the spread of infection through the bloodstream (such as sepsis). Bacteria are the most common cause, but viruses and fungi can also lead to septic arthritis.

2. How Is Septic Arthritis Treated?

Treatment involves draining the infected fluid from the joint and using antibiotics to eliminate the infection. In severe cases, surgical intervention may be needed to clean the joint thoroughly.

3. Can Septic Arthritis Be Prevented?

Yes, the risk can be reduced by treating infections in the body promptly, keeping wounds clean, and following post-surgery care guidelines. Vaccinations and maintaining a strong immune system can also help in prevention.

4. What Are the Symptoms of Septic Arthritis?

Symptoms include:

Severe pain in the affected joint.
Swelling and warmth in the joint.
Difficulty moving the joint and stiffness.
Fever and high body temperature.

5. How Is Septic Arthritis Diagnosed?

Diagnosis is done through:

Joint Aspiration: A sample of fluid is taken from the joint to analyze and determine the type of infection.
Blood Tests: To check for signs of inflammation or an infection spreading in the body.
Medical Imaging: X-rays or MRI scans help detect joint damage or any abnormal changes.

What Is Septic Arthritis?

Septic arthritis occurs when an infection reaches the joint, causing severe inflammation that can lead to joint damage if not treated quickly. This condition requires immediate medical attention to prevent serious complications. The infection can be caused by bacteria, viruses, or fungi, spreading to the joint through the bloodstream, a wound, or a surgical procedure.

Who Is at Higher Risk of Developing Septic Arthritis?

Certain groups of people have a higher risk of developing septic arthritis, including:

Young children and elderly individuals.
People with weakened immune systems, such as those with diabetes or cancer.
Individuals with chronic illnesses or those taking immunosuppressive medications.
IV drug users.

What Are the Sources of Infection?

Infection occurs when certain germs enter the body from external sources, such as:

Skin injuries: Using contaminated needles, wounds caused by sharp objects like knives, or open fractures.
Respiratory, digestive, or urinary systems: Germs can spread from these areas to the joint through the bloodstream, especially in cases of respiratory infections or gastrointestinal infections.

Is Septic Arthritis Contagious?

The disease itself is not contagious, meaning it cannot be transmitted from one person to another through touch or sneezing. However, some microorganisms that cause septic arthritis can be contagious, such as:

Neisseria gonorrhoeae bacteria, which cause gonorrhea.
Staphylococcus bacteria, which can spread through wounds or contaminated objects.
HIV (Human Immunodeficiency Virus), which weakens the immune system, making a person more vulnerable to infections.

Can Septic Arthritis Be Treated at Home?

No, there is no home treatment for this condition, as it is a medical emergency that requires immediate intervention. Treatment involves strong antibiotics, draining the infected joint fluid, and sometimes surgical intervention, so it cannot be managed at home.

What Are the Causes of Septic Arthritis?

The causes vary from person to person, but some key risk factors include:

Bacterial infections: The main cause, where bacteria attack the joint directly, leading to severe inflammation.
Viral infections: Some viruses can cause joint inflammation, which may develop into septic arthritis.
Fungal infections: In rare cases, fungal infections can reach the joint and cause inflammation.
Injuries and wounds: Deep wounds or joint surgeries increase the risk of germs entering and causing infection.
Anemia and malnutrition: A lack of essential nutrients weakens the immune system, making the body more susceptible to infections.
Diabetes: People with diabetes are more prone to infections due to poor wound healing and weakened immunity.
Immunodeficiency diseases: Conditions like HIV or the use of immunosuppressive medications can make the body unable to fight infections.
Repeated trauma to the joint: Frequent injuries or severe bruises, especially in the knee, can make the joint more vulnerable to infection.
Blood circulation problems around the joint: Poor blood flow to the joint can reduce the body’s ability to fight infections.
Blood pooling in the hands and feet: Weak circulation can cause bacteria to accumulate in certain areas, increasing the risk of infection.

How Does Septic Arthritis Affect the Body?

Septic arthritis is not just a problem in the joint; it can be a serious condition affecting the entire body, especially if the infection spreads to the bloodstream. Some of the main effects include:

Fever: The body responds to the infection with a high temperature, which is a sign of severe inflammation.
Swelling and redness: Fluid builds up in the affected joint, causing severe pain and redness in the surrounding skin.
General weakness: As the body fights the infection, the patient may feel extreme fatigue and weakness.
Impact on vital organs: In severe cases, the infection can spread to organs like the heart or kidneys, leading to more serious health complications.

What Are the Symptoms of Septic Arthritis?

The symptoms are usually very noticeable and cause severe pain for the patient. The most common symptoms include:

Swelling and stiffness in the affected joint.
Severe pain in the infected joint.
Difficulty moving the joint due to inflammation.
Redness of the skin around the joint.
High fever.
Fatigue and general weakness.
Loss of appetite, where the patient may feel unable to eat properly.
Skin rash in some cases.
Rapid heartbeat due to inflammation.

What Are the Risk Factors for Developing Septic Arthritis?

Some people are at a higher risk of developing this condition due to specific factors. The most at-risk groups include:

Children and the elderly, as their immune systems are weaker.
People with open wounds, which make it easier for bacteria to enter the body.
Individuals with weakened immune systems, such as those with immune deficiencies or those taking immunosuppressive medications.
Cancer and diabetes patients, as these conditions reduce the body's ability to fight infections.
Patients with rheumatoid arthritis, because they take medications that lower the body's immunity.
People with artificial joints, such as knee or hip replacements, as infections can easily spread to these areas.
Gonorrhea patients, since certain bacteria that cause gonorrhea can also lead to septic arthritis.
IV drug users, as using unsterilized needles can introduce bacteria into the joints.

How Is Septic Arthritis Diagnosed?

Early diagnosis is crucial to prevent joint damage or serious complications. The diagnostic process includes:

Medical History & Physical Examination

The doctor asks about the patient’s symptoms and risk factors.
A physical examination is performed to check for swelling, pain, and redness in the affected joint.

Laboratory Tests

Blood tests: To detect inflammation or infection in the body.
Joint fluid analysis: A sample of synovial fluid is drawn from the affected joint and tested for bacteria, white blood cells, or crystals to determine the cause of the infection.

Imaging Studies

X-ray: Helps detect any joint damage.
MRI and CT scans: Provide clearer images of the joint and surrounding tissues, helping to assess the extent of the infection.

When Should You See a Doctor?

You should see a doctor immediately if your symptoms worsen or if new symptoms appear, such as:

Increased pain and swelling in the joint.
Severe difficulty in moving the joint.
High fever.
Persistent fatigue and general weakness.
