About Streptococcus Pneumonia

Overview

Streptococcus pneumoniae, also known as pneumococcus, is a type of bacteria that commonly resides in the upper respiratory tract of healthy individuals. It is considered a commensal bacterium, meaning it coexists without causing harm. However, in certain vulnerable populations such as children, older adults, and those with weakened immune systems, pneumococcus can cause pneumonia, an infection of the lungs that may be life-threatening. Streptococcus pneumonia may also be called pneumococcal pneumonia. Symptoms of Streptococcus pneumonia include chest pain, coughing, fever or chills, and difficulty breathing. Antibiotics, especially when started early in the infection, can treat the infection and help prevent complications.

Causes and Risk Factors

Streptococcus pneumonia is caused by an infection in the lungs by bacteria called streptococcus pneumoniae or pneumococcus. Streptococcus pneumonia is often mild but can be severe and life-threatening.

Risk factors for Streptococcus pneumonia include:

• Age: Children under age 5 years old or adults over age 65 years old.
• Alaska Native, African American, and some American Indian people.
• Cigarette smoking.
• Alcohol use disorder.
• Chronic lung disease such as chronic obstructive pulmonary disease (COPD), emphysema, and asthma.
• Chronic conditions such as liver disease, kidney disease, and heart disease.
• Diabetes.
• Weakened immune system, such as HIV infection, kidney failure, sickle cell disease, cancer, and organ transplant.

It's important to note that these risk factors may increase susceptibility to Streptococcus pneumonia but do not guarantee its development. It's always recommended to consult with a healthcare professional for personalized advice and guidance.

Symptoms

The most common early symptoms of Streptococcus pneumonia, a type of pneumonia, include:

• Fever and chills
• Cough, which may produce green, yellow, or even bloody phlegm
• Rapid breathing or difficulty breathing
• Chest pain
• Fatigue

As the infection progresses or becomes more severe, the following symptoms may occur:

• Confusion or delirium, especially in older adults
• Loss of appetite
• Nausea and vomiting

It is important to note that in older patients, fatigue or confusion can be the only or most noticeable symptom. Additionally, complications of pneumococcal pneumonia can include:

• Empyema (infection around the lungs and in the chest cavity)
• Pericarditis (inflammation of the outer lining of the heart)
• Endobronchial obstruction (blockage of the airway that allows air into the lungs), with atelectasis (collapse within the lungs) and abscess (collection of pus) in the lungs
• Meningitis
• Bacteremia (infection of the blood)

If you experience any of these symptoms or suspect you may have pneumonia, it is essential to seek medical attention for proper diagnosis and treatment.

Diagnosis

To diagnose Streptococcus pneumoniae infection, the following examinations, tests, and procedures are commonly performed:

• Medical History and Physical Examination: The healthcare provider will ask about symptoms and use a stethoscope to check the lungs. They may take your temperature to check for fever or use a device on your finger to check the level of oxygen in your blood.
• Blood Tests: A sample of blood may be tested to look for signs of infection. A sample of blood may also be tested for the presence of bacteria. If bacteria are found, they can be tested to determine which antibiotics will be effective against it.
• Sputum Test: Mucus or phelgm after a deep cough may be tested to look for presence of streptococcus pneumoniae bacteria. If bacteria are found, they can be tested to determine which antibiotics will be effective against it.
• PCR (Polymerase Chain Reaction) Test: This test detects the presence of Streptococcus pneumoniae DNA in samples, providing a rapid diagnosis.
• Chest X-ray: This allows the doctor to look for signs of infection in the lungs.

The healthcare provider may perform other examinations, tests or procedures based on the individual situation.

Treatment Options

The goal of treatment for Streptococcus pneumonia is to cure the infection and prevent complications. Severe pneumonias may require treatment in the hospital. Here are the treatment options and how they work:

• Antibiotics: Antibiotics are the mainstay of treatment for Streptococcus pneumoniae. They work by killing or inhibiting the growth of the bacteria, helping to clear the infection.
• Supportive care: Supportive care measures, such as rest, adequate hydration, and over-the-counter pain relievers, can help alleviate symptoms and support the body's natural healing process.
• If blood oxygen levels are low, supplemental oxygen may be administered.
• Vaccination: Vaccination is an important preventive measure against Streptococcus pneumoniae. Pneumococcal vaccines stimulate the immune system to produce antibodies that can recognize and neutralize the bacteria, reducing the risk of infection. Vaccination is recommended for people at high risk of pneumococcus disease. Check with the doctor to see if vaccination is recommended based on individual factors.

Always consult with a healthcare professional for personalized advice.

Medication dosing may be affected by many factors. Check with your health care professional about dosing for your individual situation. Other side effects can occur. Check with your health care professional or read the information provided with your medication for additional side effect information.
