Do you have chest pain? Is there a collection of pus? Let's learn about this empyema!

Do you sometimes feel like your chest is constricting when you breathe, or do you have a cough that lasts for a long time with chest pain, or do you feel like you are not breathing? These may be symptoms of a common cold or other minor illness. But my friend, rarely, a serious condition can develop in our lungs with these symptoms. So, the condition we are going to talk about today is called Empyema .

What is Empyema? Let's understand it simply!

Simply put, empyema is a buildup of pus in the pleural space around your lungs. Now you might be wondering what this pleural space is. Think of your lungs as two balloons. These two balloons are inside a thin sac-like covering. The very small space between the lungs and the covering on the outside is called the pleural space. Normally, there is a very small amount of fluid there, which helps the lungs slide around easily without rubbing against each other when you breathe.

So, when pus accumulates in this pleural space, we call it empyema. When we say `pus`, you know, when we have a wound somewhere in our body, it becomes pus, and a thick liquid that is yellow, white, sometimes green, or pink comes out, right? That's what this is. This substance called pus contains things like white blood cells , dead tissue, and bacteria that cause infection. This pus is produced when our body fights an infection.

The most important thing is that if this empyema condition is not treated properly and quickly, it can gradually become worse and sometimes even life-threatening. Therefore, it is very important to be aware of this.

This is called other names, sometimes doctors call it `pyothorax` or `purulent pleuritis` . But most often the name empyema is used.

Is Empyema a COPD?

This is a question that many people ask. No, empyema is not a disease called COPD (Chronic Obstructive Pulmonary Disease) . COPD is a general term that includes various chronic lung diseases, such as chronic bronchitis ( chronic inflammation of the airways) and emphysema (damage to the air sacs in the lungs).

However, there is something to note. A person with COPD is at a higher risk of developing an infection like empyema than a healthy person. This means that COPD patients need to be especially careful about this.

Who is most likely to develop empyema?

Anyone can develop empyema. However, some people are at a higher risk. Let's take a look at who they are:

• If you have had pneumonia before, or if you currently have pneumonia.
• If you are over 70 years old. As you age, your body's immunity decreases, so you are more likely to get these types of infections.
• If you have recently had chest surgery, either heart surgery or lung surgery.
• If you have diabetes . Diabetes can also weaken the immune system.
• If you have COPD as mentioned earlier.
• If you have bronchiectasis , a condition in which the airways in the lungs become permanently widened and their walls become weak and damaged. This makes it easier for mucus and other substances to build up and cause infections.
• If you have a blood clot, especially in the lungs.
• Some people inject drugs into a vein (IV drug use). These people are also at higher risk because germs can enter the body through dirty needles.

How common is empyema?

Actually, empyema is not a very common condition. That is, it is not a disease that occurs frequently. For example, in a country like the United States, only 32,000 cases of empyema are reported per year. That means it is not that common. But even though it is not common, it is a condition that should be taken seriously if it occurs.

What are the symptoms of empyema? Watch out for these!

The symptoms of empyema are a bit vague. That is, these symptoms can also be seen in other common diseases, so sometimes you may not think it's empyema. But look out for one or more of these things:

• Chest pain or discomfort: This pain may worsen when breathing or coughing. Some people may also feel like their chest is constricting.
• Fever: The body feels hot, and sometimes the body feels cold and shivering.
• Difficulty breathing: You may find it difficult to breathe when you are slightly tired, or you may feel short of breath even when you are just standing still.
• Cough: This can be a dry cough, sometimes accompanied by thick, colored phlegm.
• Feeling extremely tired (`fatigue`): You may feel so exhausted that you can't do anything, and you may feel sleepy all the time.
• Unexplained weight loss: If you're simply losing weight without dieting or exercising, that's also a sign to pay attention to.
• Some people may also have night sweats.

Don't be afraid of empyema just because you have one or two of these symptoms. But if they persist or get worse, definitely seek medical advice.

What are the causes of empyema?

Usually, empyema occurs when an infection in your lungs spreads to the pleural space I mentioned earlier. Think of it like some germs from inside the lungs escaping and moving into the space around the lungs.

The main and most common cause of this is pneumonia . Pneumonia is an infection of the lungs caused by bacteria, viruses, or fungi. So it is that infection that often develops into empyema.

There are several other possible causes besides pneumonia:

• Tuberculosis (TB): Tuberculosis is a bacterial infection that affects the lungs.
• Lung abscess: This is a pus-filled cavity or abscess that forms inside the lung. This is also caused by an infection.
• Chest surgery: Sometimes an infection can develop after surgery and cause empyema.
• Chest injuries or trauma: A blow to the chest, such as an accident, can damage the lungs or pleural space and cause infection.
• Sometimes, an infection in the abdominal cavity (stomach) can spread through the diaphragm into the pleural space. However, this is somewhat rare.

How quickly does empyema develop?

It usually takes about four to six weeks for a germ like bacteria to enter your lungs and develop into an empyema. This means that if something like pneumonia develops and is not treated properly, this condition called empyema can develop in a few weeks, not just a few days.

Is Empyema contagious?

This is also an important question. No, empyema is not directly transmitted from person to person. That is, you will not get empyema just by being around someone who has empyema.

But, remember this: The main causes of empyema are infections like pneumonia and tuberculosis . These underlying infections can be contagious. For example, when someone with pneumonia coughs or sneezes, germs can be released into the air and spread to others. Therefore, if the underlying disease that caused the empyema is contagious, you need to be careful about that.

How is Empyema diagnosed? What do doctors do?

If you have symptoms of empyema, you should definitely see a doctor. A doctor can tell for sure if it's empyema or something else. This is how they diagnose the condition:

1. They ask you about your medical history: They ask you a lot of questions, such as what symptoms you have, how long you have had them, whether you have had any previous illnesses, and what medications you are taking.

2. A physical examination is performed: The doctor will listen to your chest with a stethoscope, tap your chest, and check your breathing pattern.

3. Taking a sample of fluid: This is the most important step. If there is a suspicion of fluid (pus) in the pleural space, the doctor will use a thin needle to remove some of the fluid and send it to the lab for testing. This is called a thoracentesis . This is done with a numbing medication, so it won't hurt much.

If your doctor suspects that you have empyema, they will order several more tests to confirm it.

Additional tests to diagnose empyema

• Imaging tests:
• Chest X-ray: This can give a rough idea of ​​whether there is fluid in the pleural space and how much.
• CT scan: This gives clearer, more detailed images than an X-ray. It can show the location and amount of fluid, and whether there are any other problems with the lungs.
• Ultrasound scan: This can also be used to check the amount of fluid in the pleural space. This is especially helpful in determining where to insert the needle when taking a sample of the fluid (thoracentesis).

After these images, the fluid sample is sent to the lab for various tests. They look for things like whether there is pus in it and what kind of germs it contains (cultures).

• Blood tests:
• Blood tests are done to see if you have an infection.
• The white blood cell count (WBC) is checked. This count usually increases when there is an infection.
• A test called C-reactive protein (CRP) is done. This can also help determine if there is an infection or inflammation in the body.
• Sometimes a blood culture may be done to see if there are any germs in the blood.

It is based on the information obtained from all of these tests that the doctor will determine exactly whether you have empyema and what its condition is.

Can Empyema be cured? What are the treatments?

Yes, the good news is that empyema is treatable . But it needs to be diagnosed early and treated properly. Treatment has two main goals:

1. Removing pus from the pleural space.

2. Treatment to kill the germs that caused the infection (this is usually done with antibiotics ).

Now let's see how to remove this pus:

• Thoracentesis: In the early stages of empyema, or if the amount of pus is small, the doctor may insert a thin needle and tube (catheter) through the chest into the pleural space and drain some of the pus. Sometimes, a small tube (chest tube or drainage tube) may be left in place for several days to continue draining the pus.
• Fibrinolytic therapy: Sometimes the pus can be very thick and clotted. Then it doesn't come out easily through the tube. In such cases, the doctor can inject a medicine into the pleural space through the chest tube. This medicine works by dissolving some of the thick pus. Then it can be easily removed.
• Surgery:

If the empyema is severe, if the pus has spread to many areas, if it has formed fibrous tissue, or if other treatments have not helped, your doctor may need to perform surgery. There are several types of surgery:

• Video-Assisted Thoracic Surgery (VATS): This involves making several small incisions in the chest, inserting a camera and special instruments, and cleaning the pleural space, removing pus and thickened membranes. This is done with a relatively small incision, which allows for faster healing.
• Thoracotomy and Decortication: If the condition is too severe to be treated with VATS, a thoracotomy (opening the chest) may be performed. This allows the doctor to directly view the lungs and remove any thickened, constricting membrane (called decortication) and pus.

Your doctor will decide which treatment is right for you after considering many factors, such as the severity of your empyema and your general health.

What are the medications for empyema?

To control and eliminate the infection, your doctor will prescribe antibiotics . These may be given intravenously (IV), or as pills or capsules. They may be given IV first and then switched to oral medications.

Some of the most commonly used antibiotics are:

• `Amoxicillin-clavulanate`
• `Piperacillin-tazobactam`
• `Imipenem`
• `Meropenem`
• Sometimes medications like `Clindamycin` or `Metronidazole` can also be added.

These are just examples. Your doctor will determine the antibiotic and dosage that is right for you and your infection. Never take any antibiotic you feel like without medical advice.

How quickly will I recover after treatment?

This is also something that can vary from person to person.

• Antibiotics usually take two to six weeks. Sometimes longer. The most important thing is to take the medicine exactly as prescribed by your doctor, even if you feel a little better. Otherwise, the infection may not go away completely and may come back, making it harder to treat, and the medicine may not work.
• After a thoracentesis ( the removal of pus with a needle), there may be some discomfort at the site of the needle insertion for a few days or a week. The doctor will give you painkillers for this.
• If you have a chest tube , you may feel some discomfort until it is removed.
• If you have major surgery (VATS or Thoracotomy) , it can take four to six weeks, or even longer, to fully recover and resume normal activities. During this time, it is very important to rest and exercise as directed by your doctor.

How can you prevent the development of empyema?

"Prevention is better than cure." The best and most important way to prevent the development of empyema is to treat any lung infection, especially pneumonia, promptly and properly.

• If you have symptoms of pneumonia (cough, phlegm, fever, chest pain, difficulty breathing), do not ignore it, see a doctor immediately, and take the medication exactly as prescribed.
• If you smoke, quitting is a great way to keep your lungs healthy.
• Good hygiene habits, such as washing your hands frequently and being careful in crowded places, are also important.
• There are vaccines available for some people (e.g., the elderly, people with other illnesses) against pneumonia. Ask your doctor about them.

What can I expect if I have empyema?

We've already talked about how empyema is not a common condition. In most cases , if it's diagnosed and treated early, that is, as soon as symptoms start, it can be completely cured before it gets worse.

However, if not treated properly, or if you have other long-term medical conditions (comorbidities) such as diabetes, heart disease, or kidney disease, it can be fatal in between 5% and 30% of people with empyema. That means it can be life-threatening.

If empyema develops in people with weakened immune systems (e.g., HIV-infected people, cancer patients, organ transplant recipients), the mortality rate can be as high as 40%. That means it is very dangerous.

So, if you have symptoms of empyema, the best thing to do is to see a doctor without wasting any time. If the doctor prescribes antibiotics, be sure to take the full course of medication to ensure that the infection is completely gone and does not come back.

What questions should you ask the doctor?

When you go to see your doctor, it's a good idea to ask questions like these to get a clear understanding of your condition:

• "Doctor, how exactly did you conclude that I had empyema? What tests confirmed it?"
• "If I don't have empyema, what other condition could be causing these symptoms?"
• "How did I get empyema? Is there a specific reason for it?"
• "How serious is my empyema? What stage is it at?"
• "What kind of treatment do you recommend for me? What are the expectations for it?"
• "How long should I take these antibiotics, how many times a day, before or after meals?"
• "Can these medications cause any side effects? If so, what should I do?"
• "How should I store these antibiotics? (e.g., in the refrigerator or at room temperature?)"
• "Do I need to come back and show up (`follow-up appointments`)? When is that?"
• "Are there any special things I should be careful about in terms of food, drink, and daily activities during this time?"

Don't be afraid to ask these questions. Having a good understanding of your illness is very important for a speedy recovery.

What is the difference between Empyema and Pneumonia?

Although both of these are lung infections, there is a slight difference.

• Pneumonia is an infection of one or both of your lungs, or the lung tissue itself . It can be caused by bacteria, viruses, or fungi. If you have pneumonia, you may cough up infected mucus.
• Empyema is a collection of pus in the pleural space around your lungs . It is often caused by bacteria that cause pneumonia (that is, as a complication of pneumonia). If you have empyema, the pus will not come out when you cough it up. The pus will need to be treated with antibiotics, or a doctor will need to drain it with a needle or surgery.

What is the difference between an empyema and a lung abscess?

Even though pus collects in both of these, it's in two places.

• A lung abscess is an abnormal collection of dead tissue and pus that forms inside the lung tissue . This abscess stays in one place and does not move around.
• Empyema is a collection of pus in the pleural space outside the lungs. This pus can be concentrated in one place or spread throughout the pleural space.

What is the difference between Empyema and Pleural Effusion?

These two can be confused.

• Pleural effusion is the accumulation of extra fluid between the thin membranes between your lungs and the pleural space. Some people also call it 'water on the lungs'. This fluid can build up for a variety of reasons (such as heart disease, kidney disease, cancer). This fluid may or may not be pus.
• Empyema is the accumulation of pus, specifically in the pleural space. That is, not all pleural effusions are empyemas, but empyema is a pleural effusion that contains pus (infectious).

What is the difference between Empyema and Parapneumonic Effusion?

Let's explain this a little.

• Parapneumonic effusion is a type of pleural effusion. It occurs as a result of pneumonia . This means that fluid accumulates in the pleural space due to pneumonia. This fluid may initially be just fluid (without pus).
• If this parapneumonic effusion becomes infected with bacteria and pus forms in it, then we call it `Empyema` . That is, a parapneumonic effusion can develop into an empyema.

Finally, the most important things to remember (Take-Home Message)

So, my friend, I hope you now have a better understanding of empyema. Keep these points in mind:

• Empyema is a condition in which pus collects in the pleural space around your lungs and requires treatment.
• This usually causes symptoms affecting the chest and breathing (chest pain, difficulty breathing, fever, cough).
• Although this is not a very common condition, if a doctor detects empyema early, you have a much higher chance of making a full recovery.

Most importantly: If left untreated, or if you have other medical conditions, such as diabetes, empyema can be fatal. So, if you have difficulty breathing or other suspicious chest symptoms, don't ignore them as normal, and definitely see a doctor right away.

Your doctor can diagnose whether you have empyema or something else, find the cause, and give you the most effective, appropriate treatment. Remember, early treatment and following your doctor's instructions are the best way to stay healthy!
