Epiglottitis
Disease Details
Family Health Simplified
- Description
- Epiglottitis is a potentially life-threatening condition characterized by inflammation and swelling of the epiglottis, which can obstruct the airway and cause severe respiratory distress.
- Type
- Epiglottitis is an acute inflammatory disease, typically caused by bacterial infection, especially Haemophilus influenzae type b (Hib). It is not a genetic disorder and thus does not involve genetic transmission.
- Signs And Symptoms
-
Epiglottitis is associated with fever, throat pain, difficulty in swallowing, drooling, hoarseness of voice, and stridor. Onset is typically over a day. The throat itself may appear normal.
Stridor is a sign of upper airway obstruction and is a surgical emergency. The child often appears acutely ill, anxious, and will have very quiet shallow breathing often keeping the head held forward and insisting on sitting up in bed, commonly called the "tripod position." The early symptoms are usually insidious but rapidly progressive, and swelling of the throat may lead to cyanosis and asphyxiation.Adults commonly present with less dramatic breathing symptoms than children due to them having wider airways to begin with, so their main symptoms are usually a severe sore throat and difficulty swallowing. The back of the throat appears normal in 90% of adult patients, so epiglottitis should considered when there is pain out of proportion to exam or when pain is caused by pressing on the external windpipe. Adult epiglottitis is often referred to as supraglottitis. In contrast to children, the symptoms are non-specific, sub-acute and can be unpredictable. - Prognosis
- With appropriate treatment, the risk of death among children with the condition is about one percent and among adults is seven percent. Elsewhere, it has been reported that only one percent of adults diagnosed with epiglottitis die from the disease. Some people may develop pneumonia, lymphadenopathy, or septic arthritis.Between 1998 and 2006, there were an average of 36 deaths per year in the United States attributed to epiglottitis, giving a case-fatality rate of 0.89% during that time period.Patients who recover from necrotizing epiglottitis often regain their ability to swallow foods and liquids despite the tissue damage.
- Onset
- Epiglottitis typically has a rapid onset, occurring over hours to a few days. The condition can be life-threatening, requiring immediate medical attention. Common symptoms include severe sore throat, difficulty swallowing, drooling, fever, and stridor.
- Prevalence
- The prevalence of epiglottitis has significantly decreased since the introduction of the Hib (Haemophilus influenzae type b) vaccine. In countries with high vaccination coverage, the incidence is estimated to be about 1 per 100,000 children per year. In adults, the incidence is generally lower but varies by region and underlying health conditions.
- Epidemiology
- While, historically, young children were mostly affected, it is now more common among older children and adults. Before Haemophilus influenzae (Hib) immunization children of two to four were most commonly affected. With immunization about 1.3 per 100,000 children are affected a year. It has been reported that only 0.5 per 100,000 American children are diagnosed every year, while the incidence in American adults is about 1 to 4 per 100,000. A 2010 retrospective study revealed the average age of patients admitted to American hospitals for epiglottitis was about 45, but patients under the age of 1 and over the age of 85 are also particularly vulnerable.
- Intractability
- Epiglottitis is a potentially life-threatening condition that causes inflammation and swelling of the epiglottis, which can obstruct the airway. It is not typically considered intractable as it can often be effectively treated with prompt medical intervention, which may include antibiotics, corticosteroids, and airway management. However, without timely treatment, it can lead to severe complications.
- Disease Severity
- Epiglottitis is a potentially life-threatening condition characterized by inflammation and swelling of the epiglottis, which can cause severe breathing difficulties. Immediate medical intervention is often required to secure the airway and provide appropriate treatment.

- Pathophysiology
- Epiglottitis is an inflammation of the epiglottis, which can lead to a life-threatening airway obstruction. The pathophysiology involves infection and subsequent swelling of the epiglottis, which is located at the base of the tongue. Inflammation can cause the epiglottis to swell, potentially blocking the trachea and impairing breathing. Common causative agents include bacteria such as Haemophilus influenzae type b (Hib), Streptococcus pneumoniae, and Staphylococcus aureus. Other factors contributing to epiglottitis include trauma, thermal injury, or other infections. Inflammation leads to edema and the rapid onset of symptoms such as sore throat, difficulty swallowing, fever, and stridor. This condition requires immediate medical attention to secure the airway and administer appropriate antimicrobial therapy.
- Carrier Status
- Carrier status for epiglottitis is not typically a relevant concept because epiglottitis is an acute condition rather than a chronic carrier state. It is often caused by bacterial infections, particularly Haemophilus influenzae type b (Hib), although other bacteria and viruses can also be responsible. With the introduction of the Hib vaccine, the incidence of epiglottitis has significantly decreased.
- Mechanism
-
Epiglottitis is a potentially life-threatening condition characterized by inflammation and swelling of the epiglottis, a small cartilage located at the base of the tongue that covers the windpipe during swallowing.
**Mechanism:**
Epiglottitis primarily occurs due to infection, although trauma and other factors can also play a role. The classic cause is bacterial infection, most notably by *Haemophilus influenzae* type b (Hib). However, other bacteria such as *Streptococcus pneumoniae*, *Streptococcus pyogenes*, and *Staphylococcus aureus* can also be involved. The inflammation leads to swelling of the epiglottis and surrounding tissues, which can obstruct the airway and cause respiratory distress.
**Molecular Mechanisms:**
The molecular mechanisms of epiglottitis involve the immune response to bacterial invasion. When bacteria such as *Haemophilus influenzae* type b infect the epiglottis, they can adhere to the mucosal surface and evade the initial immune defenses. These bacteria possess various virulence factors, including a polysaccharide capsule, which helps them resist phagocytosis and complement-mediated lysis.
The host immune response involves the recruitment of inflammatory cells, such as macrophages and neutrophils, to the site of infection. Cytokines and chemokines released by these cells increase vascular permeability, leading to the edema and swelling characteristic of epiglottitis. The inflammatory response aims to eliminate the bacteria but also contributes to the narrowing of the airway.
Other molecular players, such as bacterial adhesins, lipopolysaccharides (in gram-negative bacteria), and toxins, can further exacerbate the inflammatory process by activating additional immune signaling pathways. This combination of direct bacterial action and host immune response underlies the pathophysiology of epiglottitis. - Treatment
-
Epiglottitis is a medical emergency and requires immediate treatment. The primary treatments for epiglottitis include:
1. **Airway Management**:
- Ensure the airway remains open; intubation may be necessary.
- In severe cases, a tracheostomy might be performed.
2. **Antibiotics**:
- Intravenous antibiotics are administered to combat the infection, typically targeting Haemophilus influenzae type b (Hib) and other potential bacteria like Streptococcus pneumoniae and Staphylococcus aureus.
3. **Corticosteroids**:
- These may be given to reduce swelling and inflammation of the epiglottis.
4. **Supportive Care**:
- Intravenous fluids to maintain hydration.
- Monitoring in an intensive care unit (ICU) may be required.
5. **Avoiding Additional Stress**:
- Keeping the patient calm and in a comfortable position to avoid further airway obstruction.
Immediate medical attention is vital for effective treatment and management of epiglottitis. - Compassionate Use Treatment
-
Compassionate use, off-label, or experimental treatments for epiglottitis might be considered for severely ill patients who do not respond to standard therapies. These treatments are typically considered under strict medical supervision and might include:
1. **Corticosteroids:** Though commonly used to reduce inflammation, their use in epiglottitis is off-label and remains controversial due to mixed evidence of benefit.
2. **Nebulized Epinephrine:** Sometimes used off-label to reduce airway swelling in emergency situations, especially if there's significant respiratory distress.
3. **Broad-spectrum Antibiotics:** Beyond the standard treatment with third-generation cephalosporins or ampicillin-sulbactam, additional or alternative antibiotics may be considered based on culture results and clinical response.
4. **Monoclonal Antibodies:** Under experimental protocols, these might be used to target specific infections or inflammatory pathways involved in epiglottitis, although this is currently rare.
Always consult with healthcare professionals for current best practices and emerging treatments. - Lifestyle Recommendations
-
Epiglottitis is a potentially life-threatening condition characterized by inflammation of the epiglottis, which can obstruct the airway. Here are some lifestyle recommendations for preventing and managing epiglottitis:
1. **Vaccination:**
- Ensure you and your children receive the Haemophilus influenzae type b (Hib) vaccine, which is a primary cause of epiglottitis.
- Stay up to date with other recommended vaccinations, like pneumococcal and influenza vaccines, to reduce the risk of infections that could contribute to epiglottitis.
2. **Good Hygiene:**
- Practice regular hand washing with soap and water.
- Use hand sanitizers if soap and water are not available.
- Avoid close contact with people who are sick.
3. **Avoid Tobacco Smoke:**
- Do not smoke and avoid exposure to secondhand smoke as it can irritate the airways and increase susceptibility to infections.
4. **Healthy Lifestyle:**
- Maintain a balanced diet rich in vitamins and minerals to support your immune system.
- Ensure regular physical activity.
- Get adequate sleep to keep your immune system strong.
5. **Recognize Symptoms Early:**
- Be aware of symptoms of epiglottitis such as severe sore throat, fever, difficulty swallowing, drooling, and muffled voice.
- Seek immediate medical attention if you or someone else exhibits these symptoms, as epiglottitis can progress quickly and requires prompt treatment.
6. **Avoid Sharing Personal Items:**
- Do not share eating utensils, drinking glasses, or other personal items that may spread infections.
By following these recommendations, you can help reduce the risk of epiglottitis and manage overall health more effectively. - Medication
-
Epiglottitis is a potentially life-threatening condition that involves inflammation of the epiglottis. Immediate treatment is crucial and may involve:
1. **Antibiotics**: Typically prescribed to treat bacterial infections. Common choices include:
- Ceftriaxone or Cefotaxime
- Ampicillin/sulbactam
2. **Corticosteroids**: To reduce inflammation, though their use is somewhat controversial.
3. **Airway Management**: The first priority for epiglottitis is securing the airway. In severe cases, endotracheal intubation or a tracheostomy may be necessary.
Treatment should be administered in a hospital setting where the airway can be monitored and secured if needed. - Repurposable Drugs
-
Repurposable drugs for epiglottitis include:
1. **Ceftriaxone**: Originally used for a variety of bacterial infections, this antibiotic can be effective in treating the bacterial causes of epiglottitis, particularly Haemophilus influenzae type b.
2. **Ampicillin/sulbactam**: This combination antibiotic is useful for its broad-spectrum activity against many bacteria that could cause epiglottitis.
3. **Dexamethasone**: Initially used for its anti-inflammatory properties in various conditions, it can help reduce swelling of the epiglottis in severe cases of epiglottitis.
4. **Cefotaxime**: Another broad-spectrum antibiotic effective against many of the bacteria that can cause epiglottitis.
"Nan" typically means 'not applicable' or could stand for 'nanoparticles'; clarification is needed if a different context is intended. - Metabolites
-
Metabolites specifically associated with epiglottitis are not well-documented, as epiglottitis is typically an acute inflammatory condition caused by infectious agents like Haemophilus influenzae type b (Hib). The disease involves the inflammation of the epiglottis, leading to potential airway obstruction, and its diagnosis and management primarily hinge on clinical evaluation and sometimes imaging rather than metabolic profiling.
If you need more specific details related to metabolic changes or diagnostic markers in bacterial infections that might complicate or cause epiglottitis, it would be important to look at general markers of infection and inflammation, such as elevated levels of C-reactive protein (CRP) or white blood cell counts, but these are not specific metabolites. - Nutraceuticals
- Nutraceuticals are not a primary treatment for epiglottitis, as this condition requires urgent medical intervention due to the risk of airway obstruction. The focus is usually on securing the airway and administering appropriate antibiotics and anti-inflammatory medications. Nutraceuticals, such as vitamins, minerals, or herbal supplements, are not proven to address the acute and life-threatening nature of epiglottitis. Prompt medical care is essential.
- Peptides
- Epiglottitis is an inflammatory condition of the epiglottis, which can lead to severe airway obstruction. It is often caused by bacterial infections, notably Haemophilus influenzae type b (Hib). Symptoms include a sore throat, fever, difficulty swallowing, and stridor. Emergency medical treatment is critical to secure the airway and administer appropriate antibiotics. The development and use of the Hib vaccine have significantly reduced the incidence of epiglottitis.
