Upper respiratory infection vs. bronchitis. Bronchitis vs Upper Respiratory Infections: Key Differences and Treatment Options
What are the main differences between bronchitis and upper respiratory infections. How can you distinguish between their symptoms. What treatment options are available for each condition. When should you seek medical attention for respiratory symptoms.
Understanding Bronchitis: Symptoms, Causes, and Treatment
Bronchitis is a lower respiratory tract infection that affects the bronchioles, the air-transporting tubes of the lungs. Unlike upper respiratory infections, bronchitis impacts structures below the voice box (larynx). The condition occurs when the bronchioles become inflamed and produce excess mucus, typically due to a viral infection, although bacteria can also be responsible.
Common Symptoms of Acute Bronchitis
- Frequent coughing (with or without mucus)
- Wheezing noise when coughing
- Fatigue
- Chest soreness, especially when coughing
- Sore throat
- Headache
- Mild body aches or fever
Acute bronchitis symptoms usually persist for 10 to 14 days, though some may linger for up to three weeks. Treatment often involves rest, hydration, and over-the-counter medications to manage symptoms. In cases of bacterial bronchitis, antibiotics may be prescribed.
Is bronchitis contagious? Acute bronchitis is indeed contagious, while chronic bronchitis, a long-term condition falling under the chronic obstructive pulmonary disease (COPD) umbrella, is not. Chronic bronchitis is primarily caused by smoking tobacco, with long-term exposure to air pollution, certain chemicals, and secondhand smoke also contributing factors.
Exploring Upper Respiratory Tract Infections: Types and Symptoms
Upper respiratory tract infections (URIs) affect the upper portion of the respiratory system, including the nose, mouth, throat, and voice box. These infections are caused by various viruses and bacteria that can spread through respiratory droplets or physical contact.
Common Types of Upper Respiratory Infections
- Common cold
- Sinusitis (sinus infection)
- Laryngitis
- Tonsillitis
- Epiglottitis
It’s worth noting that influenza (flu) and COVID-19 can impact both the lower and upper respiratory tracts, with COVID-19 typically starting in the upper respiratory tract and potentially spreading to the lower.
Typical Symptoms of Upper Respiratory Tract Infections
- Sore throat
- Cough
- Nasal congestion or runny nose
- Post-nasal drip
- Sneezing
- Fatigue
- Headache
How long do upper respiratory infections typically last? Most URIs resolve within two weeks, although sinusitis may persist for a longer period. Treatment generally involves rest, hydration, and over-the-counter medications to alleviate symptoms.
Distinguishing Between Bronchitis and Upper Respiratory Infections
While bronchitis and upper respiratory infections share some common symptoms, there are key differences that can help distinguish between the two conditions:
- Location: Bronchitis affects the lower respiratory tract, while URIs impact the upper respiratory system.
- Cough characteristics: Bronchitis often produces a wet, mucus-producing cough, while URI coughs are typically drier.
- Duration: Acute bronchitis symptoms may last up to three weeks, whereas most URIs resolve within two weeks.
- Chest discomfort: Bronchitis is more likely to cause chest soreness and tightness.
- Wheezing: This symptom is more common in bronchitis than in URIs.
Can bronchitis be mistaken for a cold? Yes, it’s possible to confuse bronchitis with a severe cold due to overlapping symptoms. However, the persistence and severity of cough, along with chest discomfort, are often more pronounced in bronchitis.
When to Seek Medical Attention for Respiratory Symptoms
While many cases of bronchitis and upper respiratory infections can be managed at home, there are instances when professional medical care is necessary. Consult a healthcare provider if you experience:
- Symptoms that worsen or do not improve with self-care methods
- Symptoms that disappear and then return
- Sinus pain or a severe sore throat
- A low-grade fever persisting for more than five days
- A fever higher than 101.3 degrees Fahrenheit (for adults)
- Difficulty breathing or shortness of breath
- Coughing up blood or rust-colored sputum
- Chest pain or rapid heartbeat
How can you differentiate between a serious respiratory condition and a minor infection? Pay attention to the severity and duration of your symptoms, as well as any signs of systemic illness such as high fever or extreme fatigue. When in doubt, it’s always best to consult a healthcare professional.
Prevention Strategies for Respiratory Infections
Reducing your risk of contracting bronchitis or upper respiratory infections involves adopting healthy habits and minimizing exposure to pathogens. Consider implementing the following preventive measures:
- Practice good hand hygiene by washing hands frequently with soap and water
- Avoid touching your face, especially your eyes, nose, and mouth
- Stay away from individuals who are sick
- Get vaccinated against influenza and other preventable respiratory diseases
- Quit smoking and avoid exposure to secondhand smoke
- Maintain a healthy diet and exercise routine to boost your immune system
- Keep your living and working spaces clean and well-ventilated
Are there specific foods or supplements that can help prevent respiratory infections? While no food or supplement can guarantee prevention, consuming a balanced diet rich in vitamins C and D, zinc, and antioxidants may support immune function. However, it’s essential to consult with a healthcare provider before starting any new supplement regimen.
The Impact of COVID-19 on Respiratory Health Awareness
The COVID-19 pandemic has significantly increased public awareness of respiratory health and infectious diseases. This heightened consciousness has led to several positive changes in how we approach respiratory symptoms and infections:
- Increased vigilance: People are more likely to monitor their respiratory symptoms closely and seek medical attention when necessary.
- Improved hygiene practices: The pandemic has reinforced the importance of hand washing, mask-wearing, and social distancing to prevent the spread of respiratory infections.
- Telehealth adoption: Many healthcare providers now offer remote consultations, making it easier for patients to seek advice without risking exposure to other illnesses.
- Workplace policies: Many companies have implemented more flexible sick leave policies, encouraging employees to stay home when experiencing respiratory symptoms.
How has the COVID-19 pandemic changed our approach to diagnosing and treating respiratory infections? Healthcare providers are now more likely to consider a broader range of possibilities when evaluating respiratory symptoms, leading to more comprehensive testing and treatment strategies. Additionally, there’s an increased emphasis on early intervention and isolation to prevent the spread of potentially serious infections.
Innovative Treatment Options for Respiratory Infections
As medical research advances, new treatment options for bronchitis and upper respiratory infections continue to emerge. Some innovative approaches currently being explored or implemented include:
- Targeted antiviral therapies: Researchers are developing more specific antiviral medications to combat respiratory viruses effectively.
- Immunomodulatory treatments: These therapies aim to boost the body’s natural immune response to infections.
- Probiotics: Some studies suggest that certain probiotic strains may help prevent or reduce the severity of respiratory infections.
- Nebulized medications: Delivering medications directly to the respiratory tract through nebulizers can provide more targeted relief for some conditions.
- Combination therapies: Combining multiple treatment modalities may offer more comprehensive symptom management and faster recovery.
What role does personalized medicine play in treating respiratory infections? Advances in genetic testing and biomarker analysis are allowing healthcare providers to tailor treatments more precisely to individual patients, potentially improving outcomes and reducing side effects.
The Role of Environmental Factors in Respiratory Health
Environmental factors play a significant role in respiratory health and can influence the frequency and severity of both bronchitis and upper respiratory infections. Understanding and addressing these factors can help reduce the risk of developing respiratory issues:
Air Quality
Poor air quality, both indoors and outdoors, can irritate the respiratory system and make individuals more susceptible to infections. Common air pollutants include:
- Particulate matter (PM2.5 and PM10)
- Ozone
- Nitrogen dioxide
- Sulfur dioxide
- Volatile organic compounds (VOCs)
How can you improve indoor air quality to protect your respiratory health? Consider using air purifiers with HEPA filters, maintaining proper ventilation, regularly cleaning and dusting your living space, and using natural, low-VOC cleaning products.
Climate and Weather
Extreme temperatures, humidity levels, and rapid weather changes can affect respiratory health. Cold, dry air can irritate the airways, while high humidity can promote the growth of mold and dust mites, known respiratory irritants.
Occupational Exposures
Certain occupations carry a higher risk of respiratory issues due to exposure to dust, chemicals, or other irritants. Industries with increased respiratory health risks include:
- Construction
- Mining
- Agriculture
- Manufacturing
- Healthcare
What precautions can workers in high-risk industries take to protect their respiratory health? Proper use of personal protective equipment (PPE), adherence to safety protocols, and regular health check-ups are crucial for maintaining respiratory health in these occupations.
Allergens
Allergies can exacerbate respiratory symptoms and make individuals more susceptible to infections. Common allergens include:
- Pollen
- Dust mites
- Pet dander
- Mold spores
Managing allergies through avoidance strategies, medication, or immunotherapy can help reduce the frequency and severity of respiratory symptoms.
By understanding and mitigating the impact of environmental factors on respiratory health, individuals can take proactive steps to reduce their risk of developing bronchitis, upper respiratory infections, and other respiratory conditions. Regular consultations with healthcare providers and staying informed about local environmental conditions can further support respiratory well-being.
Bronchitis vs. Upper Respiratory Infections
Do you know the difference between bronchitis and an upper respiratory tract infection (URI)? With all the medical jargon and complex terminology out there, it’s easy to get mixed up about these common respiratory conditions—and the arrival of
COVID-19 certainly hasn’t helped to simplify things. To help clear up the confusion, let’s take a closer look at bronchitis, upper respiratory tract infections, and what sets them apart.
[availability_widget]
The Basics of Bronchitis
Bronchitis (chest cold) is not an upper respiratory tract infection. Rather, it affects the air-transporting tubes of the lungs (bronchioles), which are a part of the lower respiratory tract. So, bronchitis is considered a lower respiratory infection—or an infection that impacts the lungs or structures below the voice box (larynx). Other lower respiratory tract infections include pneumonia, tuberculosis, and bronchiolitis.
Acute (short-term) bronchitis occurs when the bronchioles become inflamed and produce too much mucus. It is usually caused by a virus, although bacteria may also lead to bronchitis. Some of the most common symptoms of acute bronchitis include:
- Frequent coughing, with or without mucus
- A wheezing noise when coughing
- Fatigue
- Chest soreness, especially when coughing
- Sore throat
- Headache
- Mild body aches or fever
Symptoms of acute bronchitis typically last for 10 to 14 days, although some symptoms may linger for up to three weeks.
Treatment for acute bronchitis often involves plenty of rest, fluids, and over-the-counter medications to help control symptoms. Bacterial bronchitis may be treated with antibiotics. It’s also important to avoid smoking and exposure to airborne irritants while recovering from bronchitis. Individuals with symptoms that remain or worsen after three weeks should be evaluated by a medical professional.
While acute bronchitis is a contagious short-term infection, chronic bronchitis is a long-term condition that falls under the chronic obstructive pulmonary disease (COPD) umbrella. It is caused by smoking tobacco in most cases, although long-term exposure to air pollution, certain chemicals, and secondhand smoke may also contribute to chronic bronchitis.
Understanding Upper Respiratory Tract Infections
As you may have guessed, upper respiratory tract infections (URIs) are infections that impact the upper respiratory tract, which includes the nose, mouth, throat, and voice box.
Types of upper respiratory infections include:
- The common cold
- Sinusitis (sinus infection)
- Laryngitis
- Tonsillitis
- Epiglottitis
Influenza (flu) and
COVID-19 can impact both the lower and upper respiratory tracts, although COVID-19 typically begins in the upper respiratory tract and may spread to the lower.
Upper respiratory tract infections are caused by several types of viruses and bacteria that can travel through respiratory droplets or physical contact. These infections are incredibly widespread—in fact, the common cold is to blame for most routine doctor visits in the United States.
The signs of a upper respiratory tract infection will vary based on what type of condition is present, but a few hallmark URI symptoms include:
- Sore throat
- Cough
- Nasal congestion or runny nose
- Post-nasal drip
- Sneezing
- Fatigue
- Headache
Similar to lower respiratory infections, most upper respiratory tract infections can be treated at home by getting plenty of rest, drinking lots of water, and taking over-the-counter medications to reduce symptoms. Most infections resolve on their own within two weeks, although sinusitis may last longer. Individuals should consult with a medical professional if symptoms:
- Worsen or do not improve with self-care methods
- Go away and then return
- Include sinus pain or a severe sore throat
- Include a low-grade fever that persists for more than five days
- Include a fever higher than 101.3 degrees fahrenheit (for adults)

Upper respiratory infections are common diseases that affect the nose, throat, larynx, and other organs. Symptoms include a runny nose, cough, sore throat, difficulty breathing, and fever. Learn about the main types of upper respiratory tract infections, their causes, diagnosis and treatment.
Upper respiratory tract infections are among the most common diseases affecting our health. They include a range of flare-ups such as a runny nose, sore throat and bronchitis, as well as more serious illnesses such as a sore throat and pneumonia. Upper respiratory tract infections are usually caused by viruses and bacteria that are spread through coughing, sneezing, or contact with contaminated surfaces.
The main symptoms of an upper respiratory tract infection include runny nose, nasal congestion, sore throat, cough and fever. These symptoms can last from several days to several weeks, depending on the severity of the disease. In the case of serious infections such as pneumonia, additional symptoms may occur, such as shortness of breath, feeling weak and tired.
Prevention of upper respiratory tract infections includes the following measures: washing hands regularly with soap and water, avoiding contact with infected people, avoiding touching the face with dirty hands, wearing masks when in contact with sick people, vaccination against certain types of infections, both by vaccination and stimulating the immune system with natural means, such as proper nutrition, exercise and daily routine.
Upper respiratory infections
Upper respiratory infections are a group of diseases that attack the respiratory system and cause various symptoms such as runny nose, cough, sore throat and headache. They are usually spread from person to person through airborne droplets that are expelled when coughing or sneezing.
One of the most common infections of the upper respiratory tract is the common cold. It usually presents with a runny nose, stuffy nose, sneezing, and a runny nose. This illness is usually caused by a virus and can last from a few days to two weeks. Treatment for a cold usually includes rest, hydration, and medication to relieve symptoms.
Prevention of upper respiratory tract infections includes hygiene measures such as regular handwashing, avoiding contact with sick people, and avoiding overheating or hypothermia. It is also recommended to be vaccinated against various viral infections such as the flu. Proper nutrition, getting enough vitamins and minerals, and strengthening the immune system can help prevent upper respiratory infections.
Symptoms:
Infections of the upper respiratory tract are characterized by a number of specific symptoms, primarily affecting the nasal cavity, throat and leading to a decrease in the general condition of the body.
- Runny nose is one of the most common symptoms of upper respiratory infections. It is manifested by a stagnant state of the nasal cavity, the secretion of mucus or its blockage, as well as frequent sneezing.
- Difficulty breathing may be due to obstruction of the nasal passages, as well as due to swelling of the mucous membrane of the upper respiratory tract.
- Sore throat is also one of the main symptoms of upper respiratory tract infections. They can manifest as local discomfort in the throat, as well as more intense pain when swallowing.
- Cough can be both dry and mixed, and is often accompanied by irritation of the larynx and an unpleasant sensation behind the chest.
- Decreased general condition – upper respiratory tract infections often present with general weakness, fatigue, headache and loss of appetite.
Other symptoms, such as fever, dizziness, or skin rashes, may occur depending on the disease. If you have these symptoms, you should consult a doctor for qualified assistance and appropriate treatment.
Treatment
Treatment of upper respiratory infections depends on the cause of the infection. In most cases, viral infections are the main source of problems, and symptomatic treatment is the key approach. The main emphasis is on relieving symptoms and keeping the patient in good condition.
Most of the general recommendations include calmness, rest, hot drinks, air humidification, and regular ventilation of the premises. You should also refrain from smoking and avoid polluted or smoky places.
A range of symptoms can be alleviated by the use of traditional methods such as inhalations with herbal infusions or essential oils. Careful and regular intake of vitamins and minerals, as well as immune support, can also play a key role in the recovery process.
If the upper respiratory tract infection is due to a bacterial infection, antibiotics may be needed. However, it is worth remembering that antibiotics are not effective against viral infections, and their use may be inappropriate or even harmful.
Prevention
To prevent infections of the upper respiratory tract, it is recommended to follow a few simple rules:
- Wash your hands often. Washing your hands regularly with soap and warm water helps kill bacteria and viruses that can get on your hands.
- Use disposable wipes. Cover your mouth and nose with disposable tissues or your elbow when you cough or sneeze to prevent the spread of viruses.
- Avoid contact with sick people. Try to avoid contact with people who have symptoms of an upper respiratory tract infection, especially if you have an increased risk of complications.
- Maintain immunity. Proper nutrition, moderate exercise, adequate rest, and limiting stress will help strengthen the immune system and make it less vulnerable to infections.
- Get vaccinated. Vaccination can prevent many upper respiratory tract infections, including influenza and pneumococcal infections.
By following these tips, you can reduce your risk of getting upper respiratory infections and keep yourself healthy.
Complications
Infections of the upper respiratory tract can cause a number of complications, especially if treated incorrectly or late.
One possible complication is sinusitis. The infection can spread to the lining of the sinuses, causing inflammation. Symptoms of sinusitis can include difficulty breathing, facial pain, and headache.
Other complications may include laryngitis and tracheitis. With inflammation of the vocal cords or trachea, there are problems with the voice and hoarseness appears. It can be caused by a bacterial infection or a weakened immune system.
In addition, complications such as bronchitis or pneumonia may develop. They are the most serious complications in which inflammation spreads to the bronchi and lungs. Bronchitis is accompanied by a cough with phlegm, and pneumonia can present with severe chest pain, high fever, and shortness of breath.
In case of complications from upper respiratory tract infections, it is recommended to consult a doctor for an accurate diagnosis and appropriate treatment, as complications may require more serious and longer treatment than simple infections.
Colds
The common cold is one of the most common infections of the upper respiratory tract. It is caused by various viruses, including rhinoviruses, adenoviruses, and coronaviruses. Colds are spread from person to person through the air, especially when coughing, sneezing, or talking.
Common cold symptoms include runny nose, nasal congestion, cough, sore throat, muscle pain, fatigue and weakness. They usually appear a few days after infection and disappear within a week or two. However, in some cases, a cold can lead to complications such as sinusitis, bronchitis, or pneumonia.
Treatment of the common cold includes symptomatic therapy such as antiviral drugs, rich fluids, and rest. It is also recommended to take analgesics and suck on lozenges to relieve sore throats. It is important to remember good hygiene, including washing your hands regularly and wearing masks during a cold outbreak.
For the prevention of colds, it is recommended to strengthen the immune system through proper nutrition, physical activity and sufficient sleep. It is also helpful to avoid contact with sick people and to ventilate rooms frequently. Getting the flu vaccine can help prevent the spread of viruses that cause the common cold.
Influenza
Influenza is an acute infectious disease affecting the upper respiratory tract. The main symptoms of the flu are fever, runny nose, cough, headache, muscle and joint pain.
Influenza is caused by the influenza virus, which is transmitted from person to person through airborne droplets. The influenza virus can cause serious complications, especially in people with weakened immune systems or chronic illnesses.
Treatment for influenza includes taking antipyretics to reduce fever and relieve symptoms, as well as rest and humidify the room. To prevent influenza, vaccination, regular handwashing, and avoidance of contact with sick people are recommended.
Below is a list of recommendations for influenza prevention:
- Get influenza vaccine;
- Wash your hands regularly with soap and water;
- Avoid contact with sick people;
- Do not touch your face with dirty hands;
- Avoid crowded places during an influenza epidemic;
- Cover nose and mouth when coughing or sneezing;
- Ventilate the room;
- Maintain a healthy immune system through proper nutrition and physical activity.
As an acute and viral illness, influenza can lead to serious complications, so it is important to take preventive measures and seek medical attention if you get sick.
Angina
Angina is an acute infectious disease characterized by inflammation of the glands at the back of the throat. Angina is usually caused by bacteria such as streptococci or staphylococci. However, it can also be caused by viruses or fungi.
Symptoms of a sore throat include burning or sore throat, difficulty swallowing, swelling and redness of the glands, and swollen lymph nodes in the neck. People with angina may also experience fever, headache, and weakness.
Treating angina involves taking antibiotics to kill the bacteria causing the infection. It is important to take the full course of antibiotics, even if the symptoms have disappeared, to prevent possible complications. It is also recommended to rest and drink plenty of fluids to help the body fight infection.
Prevention of angina includes the following measures: avoid contact with sick people, wash hands regularly with soap and water, especially after visiting public places, do not smoke and avoid secondhand smoke, ventilate rooms where a sick person is, regularly strengthen the immune system through proper nutrition, physical activity and sleep.
In the event of symptoms of angina, it is necessary to consult a doctor for a correct diagnosis and treatment. Do not self-medicate or take antibiotics without consulting your doctor.
Bronchitis
Bronchitis is an inflammatory disease of the bronchi that is usually caused by a viral or bacterial infection. Most often, bronchitis develops after a cold or flu, when a virus or bacteria enters the bronchi and causes inflammation.
The main symptoms of bronchitis include a cough that may be dry or phlegm, shortness of breath, general weakness and fatigue, and fever. The cough may be accompanied by sputum production, which may be clear, white, or yellow.
Treatment of bronchitis includes antitussive drugs to relieve dry coughs and drugs that thin sputum. It is also important to drink plenty of fluids and rest to strengthen the immune system and normalize dehydration.
Prevention of bronchitis comes down to maintaining a healthy lifestyle, including regular exercise, a healthy diet and vaccinations. It is also important to avoid contact with sick people and reduce time spent in closed spaces with low ventilation.
In conclusion, bronchitis is an inflammation of the bronchi, which is manifested by coughing, shortness of breath and general weakness. It is important to follow preventive measures and seek medical help in a timely manner for the effective treatment of this disease.
Sinusitis
Sinusitis is an inflammation of the mucous membrane of one or more sinuses. It can occur as an independent disease, or be a complication of influenza, SARS or an allergic reaction. Sinusitis can affect various sinuses, including the posterior, anterior, superior, and inferior sinuses.
Symptoms of sinusitis may include a runny nose, nasal congestion, headache, pain in the forehead and cheekbones, fever, fatigue, general weakness and feeling unwell. However, symptoms can vary depending on the type of sinusitis and its severity.
Treatment for sinusitis may include antibiotics, anti-inflammatory drugs, symptomatic medications to relieve runny nose and pain, and topical treatments such as nasal sprays and drops. In some cases, surgery may be required to remove secretions or drain sinuses.
Prevention of sinusitis includes maintaining nasal hygiene, regularly moisturizing and rinsing the nose, maintaining a strong immune system, avoiding exposure to allergens, and good ventilation. In addition, it is desirable to avoid hypothermia, regularly ventilate the premises and avoid contact with patients with acute respiratory viral infections.
Rhinitis
Rhinitis is an inflammation of the nasal mucosa. It is accompanied by symptoms such as nasal congestion, discharge of mucous or purulent secretion, sneezing, itching and burning in the nose. Rhinitis can be caused by a variety of causes, including viruses, bacteria, allergens, chemical irritants, and mechanical damage.
Among the main types of rhinitis are viral, allergic and chronic rhinitis. Viral rhinitis will usually go away on its own within a few days. Allergic rhinitis is caused by allergens such as dust, pollen, and pets and can last for years if no treatment and prevention measures are taken. Chronic rhinitis can be caused by a variety of factors, including viruses, allergens, and improper medication.
Treatment of rhinitis depends on its cause and severity. For symptomatic relief, topical vasoconstrictors, hot drinks, inhalations, and heat application can be used.

Respiratory tract involvement is most often classified according to 2 criteria: temporary (acute or chronic) and topical (upper or lower airways). Otorhinolaryngologists deal with inflammation of the upper respiratory tract. In the lower respiratory tract section, pneumonia, bronchitis, and bronchiectasis are usually considered, although dysontogenetic bronchiectasis is classified as a developmental malformation. It combines lesions of the pharynx, larynx, trachea, bronchi with clinical symptoms: cough (dry or with varying degrees of hypercrinia, dyscrinia), sputum of different color and consistency, symptoms of intoxication and dyspnea (uncharacteristic for damage to large airways, but possible with tracheal dyskinesia and large bronchi).
Acute pharyngitis, tracheitis, bronchitis
If we do not consider toxic damage, then the main cause of acute bronchitis is infection, and among the infectious agents, viruses predominate, against which antibiotics are ineffective. However, in the United States, antibiotics are prescribed by doctors in 75% of cases, which, without a doubt, contributes to the sensitization of the macroorganism and the growth of microbial resistance. The list of nosologies for acute infectious inflammation of the upper respiratory tract includes pharyngitis, laryngitis, tracheitis and uncomplicated bronchitis. They are united by the nonspecific nature of inflammation, often associated with hypothermia, and viral etiology. The diagnostic algorithm for pharyngitis includes an assessment of clinical symptoms (pain, lymphadenopathy, inflammatory changes in the mucosa and tonsils) plus culture of throat swabs and serological testing. The appointment of antibiotics is indicated for purulent discharge and the severity of the condition.
Chronic bronchitis
The most well-known clinical definition of chronic bronchitis as a disease accompanied by a cough with sputum for 2 years at least 3 months a year, with the exclusion of other causes from the respiratory and cardiac systems, reflects the essence of the pathogenetic process with inflammation in the bronchi, accompanied by a violation mucociliary transport. In the presence of progressive airflow limitation and emphysema, one should speak of chronic obstructive pulmonary disease. The prevalence of chronic bronchitis in the US is 20% of the population. Deterioration in chronic bronchitis is associated with exposure to pollutants, including exposure to tobacco smoke, and acute infectious inflammation, 70% caused by bacterial flora and 30% by viruses and atypical pathogens M. pneumonia, Ch. pneumonia.
The most common bacteria are Haemophilus influenzae, Streptococcus pneumoniae and Moraxella catarrhalis.
H. influenzae is the most common pathogen isolated by sputum culture – 35-50%, S. pneumoniae – in 20%, Viruses and M. neumoniae take 3rd place as the cause of exacerbation, and C. pneumoniae – in 7%. The etiology of exacerbation of chronic bronchitis is presented in Table 1.
The most important clinical manifestations for determining an infectious exacerbation of chronic bronchitis are the classic symptoms:
• increased cough
• increase in sputum
• discoloration of sputum
• increase in dyspnea (if present)
Numerous clinical observations and rigorous multicenter studies have confirmed the role of infectious exacerbation both in aggravating the course of the disease and in its progression. Thus, a relationship was traced between the spectrum of microbial flora and the severity of bronchial obstruction. The more reduced the speed indicators, the more aggressive, virulent flora is detected (Tables 2, 3).
The degree of inoculation of microorganisms from sputum also depends on the characteristics of sputum. With mucosal sputum, the seeding rate is 38%, with colored sputum – 84%. The sensitivity of the method is 94%, the specificity is 77% for green sputum culture.
Treatment
Latest Research
In 2006, numerous studies continued on the comparative effectiveness of mainly III, IV generation of fluoroquinolones, macrolides, ketolides and b-lactam antibiotics in infectious exacerbation of chronic bronchitis. The indications for prescribing antibiotics are being clarified (for example, direct indications indicate the need for ventilation and concomitant cardiac pathology). The appointment of antibiotics in accordance with these criteria allows to achieve eradication of the microbial flora and prolong remission. Objective criteria for inflammation activity are impaired mucociliary transport, bronchial obstruction, viscoelastic properties of sputum, and sputum cytosis. A positive dynamics of these indicators was revealed during therapy with fluoroquinolones III-IV generation compared with therapy with macrolides and b-lactams. Treatment of infectious exacerbation of chronic bronchitis 200 mg cefditoren-pivoxil 2 times a day for 5 days was effective in 79.9% compared with treatment with cefuroxime axetil (250 mg 2 times a day for 10 days), effective in 82.7%. Comparative studies have shown high clinical efficacy of levofloxacin and moxifloxacin – 94 and 91%, respectively. In another study, moxifloxacin and azithromycin were clinically effective in 89% and 85%, respectively. A new fluoroquinolone – prurifloxacin 600 mg 1 time per day showed high clinical efficacy.
No one doubts the need for complex treatment of infectious exacerbation of chronic bronchitis:
• Bronchodilators
• Mucolytics
• Systemic corticosteroids, inhaled (as indicated)
• Oxygen therapy (for respiratory failure)
But these questions are beyond the scope of this article.
Indications for antibiotic therapy are clinical:
• increased cough
• increase in sputum
• discoloration of sputum
• the appearance or increase of shortness of breath
and laboratory-instrumental data:
• decrease in respiratory function
• increased sputum cytosis
• sputum culture with determination of cfu/ml
And when choosing an antibacterial drug, clinical and anamnestic criteria are mainly used.
So with simple bronchitis and rare exacerbations with a mucous character of sputum, azithromycin (Zitrocin and others), amoxicillin, amoxicillin with clavulanic acid are prescribed. With purulent bronchitis with colored sputum and frequent exacerbations, in the presence of concomitant, especially cardiovascular diseases, when taking corticosteroids, with FEV1 <50%, therapy includes amoxicillin, amoxicillin with clavulanic acid, cephalosporins II, III generation, fluoroquinolones III, IV generation. With constantly persistent infection, constant hypercrinia, there is a high probability of Pseudomonas aeruginosa, Acinetobacter, fungal flora, and therefore antipseudomonal antibiotics (ceftazidime, aminoglycosides, polymyxin) and the above-mentioned fluoroquinolones are used in the treatment of these patients.
Brochiectasis
The definition of bronchiectasis is based on pathoanatomical criteria that characterize this pathology as an irreversible expansion of the proximal and middle caliber of the bronchi as a result of damage to the muscular and connective tissue framework of the bronchial wall. Bronchiectasis may be limited to one lobe, may be widespread, but most often it is the result of acute or recurrent chronic inflammation. The most persistent clinical manifestations are chronic cough and, more often, profuse sputum production. Less common are variants of the so-called dry bronchiectasis. Shortness of breath appears depending on the presence of broncho-obstructive syndrome, emphysema and pneumofibrosis.
Etiology and pathogenesis
Bronchial obstruction:
– foreign body,
– tumor,
– enlarged lymph nodes,
– slime.
The occurrence of bronchiectasis after aspiration is possible after years, when the causal relationship is clearly lost, therefore, episodes of paroxysmal cough during meals, the state of anesthesia, and loss of consciousness are taken into account. An example of the formation of bronchiectasis that occurs during obstruction and violation of the sanitation of the bronchi can be the “middle lobe syndrome”, when it is possible to trace the relationship between obturation – pneumonia – bronchiectasis.
Malformations and hereditary diseases
Syndrome of primary ciliary dyskinesia, characterized by ultrastructural changes in the ciliary apparatus and leading to a decrease in the strength of the beating and dyskinesia of the cilia, clinically manifested by recurrent inflammation in the bronchi (bronchiectasis), infertility in men due to immobility of spermatozoa and infertility or ectopic pregnancies in women, chronic sinusitis. Sievert-Kartagener syndrome as a variant of primary dyskinesia, ciliary akinesia, is characterized by the listed symptoms and a mirror arrangement of internal organs (a consequence of the chaotic rotation of the fetus during the laying of internal organs) and is inherited in an autosomal recessive manner.
Cystic fibrosis. Hereditarily determined disease associated with dysfunction of the exocrine glands. The clinical picture depends on the location and degree of dysfunction of the glands. The defeat of the respiratory system is associated with a violation of the mucociliary apparatus, recurrence of infection with the formation of bronchiolobronchiectasis. The proportion of cystic fibrosis as a cause of bronchiectasis reaches 50%.
McLeod Syndrome
William-Campbell Syndrome
Young syndrome (in the absence of genetic pathology and normal sweat chlorides in young men with infertility, sinusitis and bronchiectasis).
The formation of bronchiectasis in these syndromes is noted after the first pneumonia, and not for many years as with cystic fibrosis.
Rheumatic diseases (rheumatoid arthritis and Sjögren’s syndrome may be accompanied by bronchiectasis. Sometimes bronchiectasis is detected earlier than articular syndrome).
Lung infections. This is mainly tuberculosis, possibly viral and mycoplasmal infections.
Smoking not as an etiological factor, but as a cause of recurrent respiratory tract infection
Abscessing, predominantly staphylococcal pneumonia
Pulmonary tuberculosis
Young Syndrome
Bronchopulmonary aspergillosis
Syndrome of “yellow nails” (lymphaedena, pleurisy, yellow nails, bronchiectasis)
Pathogenesis
The main pathogenetic mechanisms of formation of bronchiectasis are impaired bronchial patency and infectious inflammation. These interrelated processes are potentiated in the presence of certain defects in the mechanisms of lung protection (renichek dyskinesia, impaired mucus formation and mucus secretion, immunodeficiency in the humoral vein of immunity). More often, medium-sized bronchi are involved in the process, but more distal parts of the bronchial tree can also be affected. The expansion of the bronchi in the type of cylindrical or saccular bronchiectasis violates the mucociliary defense mechanism, contributes to the recurrence of infection and the progression of the process. Pus containing proteoitic enzymes (elastase, collagenase, cathepsin G) contribute to the destruction of proteins, which is accompanied by edema, ulceration, up to mucosal necrosis. Subsequent processes of granulation in themselves lead to a violation of bronchial patency, and the consequence of inflammation – metaplasia of the epithelium and sclerosis lead to irreversible changes in the bronchial wall. More often, the bronchi of the lower lobes of the left lung are involved in the process.
Clinical picture
• Cough is the main and most persistent symptom.
• Sputum is a mandatory symptom of bronchiectasis. Sputum is mucous or purulent during exacerbation with a predominant discharge in the morning. The amount of sputum can reach 500 ml / day. with uncontrolled bacterial inflammation. A rare variant of the so-called “dry” bronchiectasis is possible.
• Hemoptysis most often as evidence of active inflammation.
• Shortness of breath in the presence of broncho-obstructive syndrome, emphysema, pneumofibrosis.
• Intoxication syndrome, depending on the severity of bacterial inflammation.
• Non-pulmonary symptoms in the form of amyloidosis of the internal organs, “drum fingers” and “watch glasses” are not the most frequent and non-specific symptoms of bronchiectasis.
• Symptoms of hereditarily determined diseases (ciliary dyskinesia, cystic fibrosis, immune deficiency, MacLeod syndrome, Lewis Campbell syndrome).
Objective examination methods
X-ray examination. Able to detect bronchiectasis in 90% of cases. Rounded shadows, atelectasis, a symptom of “tram rails” are determined, with the progression of the disease – deformation of the pulmonary pattern and emphysema.
High-resolution computed tomography of the lungs reliably helps to determine the size and localization of bronchiectasis.
Brochoscopy to determine a foreign body, tumor, compression of the lymph nodes from the outside, for sanitation and bleeding.
The function of external respiration to determine the type of disorders (obstruction, emphysema, restriction) with subsequent correction of bronchial collapse on exhalation.
Bronchography (mainly as a preoperative study).
Additional research methods
Immunological studies: quantitative determination of Ig A, M, G, determination of antibodies of the IgG, E class to aspergillus, determination of total Ig E, polymerase chain reaction for CD, markers of autoimmune diseases, phagocytic activity of neutrophils, test with nitrosine tetrazole, a1-antitrypsin.
Morphological study of biopsy specimens of the bronchial mucosa (electron microscopy of cilia) with akinesia, cilia dyskinesia), determination of sperm motility, detection of carini pneumocystis.
Microbiological study for the determination of BC, Pseudomonas aeruginosa, staphylococcus aureus, culture of fungi and other pneumotropic pathogens.
Biochemical study of sweat chlorides (55–60 mev/l), blood gases.
Genetic study (genotype delta F508).
Ultrasound examination of internal organs (mirror arrangement, cor pulmonale).
Examination of ENT organs (sinusitis).
Complications
• Hemoptysis
• Pneumonia
• Abscesses
• Empyema
• Bronchopleural fistulas
• Amyloidosis of internal organs
• Respiratory failure
• Cor pulmonale
Complications in terms of severity and frequency of occurrence are more typical for patients with an early onset of the disease (with ciliary dyskinesia, cystic fibrosis, immunological deficiency) than for patients who acquired the disease in adulthood.
Treatment
• Restoration of mucociliary clearance (inhalation bronchodilators, including through a nebulizer, mucolytics of the acetylcysteine and ambroxol groups, carbocysteine in combination and combination of various routes of administration, hydration therapy, postural drainage, breathing exercises with positive expiratory pressure, vibration massage).
• Anti-inflammatory therapy with antibiotics (usually penicillin group), cephalosporins, co-trimoxazole, macrolides, ie. antibiotics used in uncomplicated chronic bronchitis. With the appearance of G-flora – fluoroquinolones, aminoglycosides, III-IV generation cephalosporins, with methicillin-resistant staphylococcus – clindamycin, vancomycin, with fungal flora – amphotericin B, etc. Courses of antibiotic therapy lasting 1-3 weeks parenterally, orally, inhalation – tobramycin for Gy flora. Inhaled tobramycin and intravenous antibiotics are needed for recurrent Pseudomonas aeruginosa. With the ineffectiveness of antibiotic therapy and clinical symptoms of bacterial inflammation, with new infiltrative changes on radiographs and a positive culture in 2 samples for CD, therapy is carried out: azithromycin 250 mg / day. or clarithromycin 500 mg twice daily, rifampin 600 mg daily, ethambutol 15 mg/kg/day, streptomycin 15 mg/kg 2 to 3 times weekly for the first 8 weeks as recommended by the American Thoracic Society and thereafter until 12 months, achieving abacilarity.
A feature of macrolides (azithromycin (Zitrocin), etc.) in the treatment of infectious diseases of the respiratory tract is their good penetration into many organs, tissues and body environments. Macrolide antibiotics accumulate in high concentrations in the tonsils, lungs, bronchial secretions, pleural fluid, middle ear cavity, paranasal sinuses, etc. The “tropism” of macrolides to the respiratory organs, along with high activity against the main pneumotropic pathogens, determines their high therapeutic efficacy in bacterial infections. respiratory tract infections. It should also be noted that almost all macrolides create concentrations in tissues that significantly exceed the level of drugs in serum.
Macrolides (azithromycin, clarithromycin, etc.) are reliably considered one of the safest antibiotics. When using macrolides, serious adverse reactions are extremely rare. Of the undesirable manifestations, nausea, vomiting, abdominal pain are more often noted, less often – diarrhea. As a rule, these side effects occur when using natural 14-mer macrolides. It has also been established that long-term use of “old” 14-mer macrolides may be accompanied by the development of cholestatic hepatitis, including due to the formation of hepatotoxic metabolites of the antibiotic (nitrosoalkane forms). Contraindications for the appointment of macrolides are pronounced violations of liver function, as well as increased individual sensitivity to these antibiotics.
Corticosteroids – oral in short courses up to 2 weeks 25-30 mg / day. or inhalation, especially in the presence of broncho-obstructive symptom and chronic bronchitis, atopy.
• Immunotherapy – vaccination against influenza and pneumococcal vaccine, immunoglobulin G, parenterally for immunodeficiency (with immunoglobulin levels below 10% of normal).
• Embolization of bronchial arteries in case of bleeding.
• Lung resection in case of local bronchiectasis and bleeding that cannot be stopped by other methods.
• Lung transplantation in the development of the terminal phase of the disease.
