Case Study: Managing Severe Asthma in an Adult

—he follows his treatment plan, but this 40-year-old male athlete has asthma that is not well-controlled. what’s the next step.

By Kirstin Bass, MD, PhD Reviewed by Michael E. Wechsler, MD, MMSc

This case presents a patient with poorly controlled asthma that remains refractory to treatment despite use of standard-of-care therapeutic options. For patients such as this, one needs to embark on an extensive work-up to confirm the diagnosis, assess for comorbidities, and finally, to consider different therapeutic options.

Case presentation and patient history

Mr. T is a 40-year-old recreational athlete with a medical history significant for asthma, for which he has been using an albuterol rescue inhaler approximately 3 times per week for the past year. During this time, he has also been waking up with asthma symptoms approximately twice a month, and has had three unscheduled asthma visits for mild flares. Based on the  National Asthma Education and Prevention Program guidelines , Mr. T has asthma that is not well controlled. 1

As a result of these symptoms, spirometry was performed revealing a forced expiratory volume in the first second (FEV1) of 78% predicted. Mr. T then was prescribed treatment with a low-dose corticosteroid, fluticasone 44 mcg at two puffs twice per day. However, he remained symptomatic and continued to use his rescue inhaler 3 times per week. Therefore, he was switched to a combination inhaled steroid and long-acting beta-agonist (LABA) (fluticasone propionate 250 mcg and salmeterol 50 mcg, one puff twice a day) by his primary care doctor.

Initial pulmonary assessment Even with this step up in his medication, Mr. T continued to be symptomatic and require rescue inhaler use. Therefore, he was referred to a pulmonologist, who performed the initial work-up shown here:

• Spirometry, pre-albuterol: FEV1 79%, post-albuterol: 12% improvement
• Methacholine challenge: PC 20 : 1.0 mg/mL
• Chest X-ray: Within normal limits

Continued pulmonary assessment His dose of inhaled corticosteroid (ICS) and LABA was increased to fluticasone 500 mcg/salmeterol 50 mcg, one puff twice daily. However, he continued to have symptoms and returned to the pulmonologist for further work-up, shown here:

• Chest computed tomography (CT): Normal lung parenchyma with no scarring or bronchiectasis
• Sinus CT: Mild mucosal thickening
• Complete blood count (CBC): Within normal limits, white blood cells (WBC) 10.0 K/mcL, 3% eosinophils
• Immunoglobulin E (IgE): 25 IU/mL
• Allergy-skin test: Positive for dust, trees
• Exhaled NO: Fractional exhaled nitric oxide (FeNO) 53 parts per billion (pbb)

Assessment for comorbidities contributing to asthma symptoms After this work-up, tiotropium was added to his medication regimen. However, he remained symptomatic and had two more flares over the next 3 months. He was assessed for comorbid conditions that might be affecting his symptoms, and results showed:

• Esophagram/barium swallow: Negative
• Esophageal manometry: Negative
• Esophageal impedance: Within normal limits
• ECG: Within normal limits
• Genetic testing: Negative for cystic fibrosis, alpha1 anti-trypsin deficiency

The ear, nose, and throat specialist to whom he was referred recommended only nasal inhaled steroids for his mild sinus disease and noted that he had a normal vocal cord evaluation.

Following this extensive work-up that transpired over the course of a year, Mr. T continued to have symptoms. He returned to the pulmonologist to discuss further treatment options for his refractory asthma.

Diagnosis Mr. T has refractory asthma. Work-up for this condition should include consideration of other causes for the symptoms, including allergies, gastroesophageal reflux disease, cardiac disease, sinus disease, vocal cord dysfunction, or genetic diseases, such as cystic fibrosis or alpha1 antitrypsin deficiency, as was performed for Mr. T by his pulmonary team.

Treatment options When a patient has refractory asthma, treatment options to consider include anticholinergics (tiotropium, aclidinium), leukotriene modifiers (montelukast, zafirlukast), theophylline, anti-immunoglobulin E (IgE) antibody therapy with omalizumab, antibiotics, bronchial thermoplasty, or enrollment in a clinical trial evaluating the use of agents that modulate the cell signaling and immunologic responses seen in asthma.

Treatment outcome Mr. T underwent bronchial thermoplasty for his asthma. One year after the procedure, he reports feeling great. He has not taken systemic steroids for the past year, and his asthma remains controlled on a moderate dose of ICS and a LABA. He has also been able to resume exercising on a regular basis.

Approximately 10% to 15% of asthma patients have severe asthma refractory to the commonly available medications. 2  One key aspect of care for this patient population is a careful workup to exclude other comorbidities that could be contributing to their symptoms. Following this, there are several treatment options to consider, as in recent years there have been several advances in the development of asthma therapeutics. 2

Treatment options for refractory asthma There are a number of currently approved therapies for severe, refractory asthma. In addition to therapy with ICS or combination therapies with ICS and LABAs, leukotriene antagonists have good efficacy in asthma, especially in patients with prominent allergic or exercise symptoms. 2  The anticholinergics, such as tiotropium, which was approved for asthma in 2015, enhance bronchodilation and are useful adjuncts to ICS. 3-5  Omalizumab is a monoclonal antibody against IgE recommended for use in severe treatment-refractory allergic asthma in patients with atopy. 2  A nonmedication therapeutic option to consider is bronchial thermoplasty, a bronchoscopic procedure that uses thermal energy to disrupt bronchial smooth muscle. 6,7

Personalizing treatment for each patient It is important to personalize treatment based on individual characteristics or phenotypes that predict the patient's likely response to treatment, as well as the patient's preferences and practical issues, such as adherence and cost. 8

In this case, tiotropium had already been added to Mr. T's medications and his symptoms continued. Although addition of a leukotriene modifier was an option for him, he did not wish to add another medication to his care regimen. Omalizumab was not added partly for this reason, and also because of his low IgE level. As his bronchoscopy was negative, it was determined that a course of antibiotics would not be an effective treatment option for this patient. While vitamin D insufficiency has been associated with adverse outcomes in asthma, T's vitamin D level was tested and found to be sufficient.

We discussed the possibility of Mr. T's enrollment in a clinical trial. However, because this did not guarantee placement within a treatment arm and thus there was the possibility of receiving placebo, he opted to undergo bronchial thermoplasty.

Bronchial thermoplasty  Bronchial thermoplasty is effective for many patients with severe persistent asthma, such as Mr. T. This procedure may provide additional benefits to, but does not replace, standard asthma medications. During the procedure, thermal energy is delivered to the airways via a bronchoscope to reduce excess airway smooth muscle and limit its ability to constrict the airways. It is an outpatient procedure performed over three sessions by a trained physician. 9

The effects of bronchial thermoplasty have been studied in several trials. The first large-scale multicenter randomized controlled study was  the Asthma Intervention Research (AIR) Trial , which enrolled patients with moderate to severe asthma. 10  In this trial, patients who underwent the procedure had a significant improvement in asthma symptoms as measured by symptom-free days and scores on asthma control and quality of life questionnaires, as well as reductions in mild exacerbations and increases in morning peak expiratory flow. 10  Shortly after the AIR trial, the  Research in Severe Asthma (RISA) trial  was conducted to evaluate bronchial thermoplasty in patients with more severe, symptomatic asthma. 11  In this population, bronchial thermoplasty resulted in a transient worsening of asthma symptoms, with a higher rate of hospitalizations during the treatment period. 11  Hospitalization rate equalized between the treatment and control groups in the posttreatment period, however, and the treatment group showed significant improvements in rescue medication use, prebronchodilator forced expiratory volume in the first second (FEV1) % predicted, and asthma control questionnaire scores. 11

The AIR-2  trial followed, which was a multicenter, randomized, double-blind, sham-controlled study of 288 patients with severe asthma. 6  Similar to the RISA trial, patients in the treatment arm of this trial experienced an increase in adverse respiratory effects during the treatment period, the most common being airway irritation (including wheezing, chest discomfort, cough, and chest pain) and upper respiratory tract infections. 6

The majority of adverse effects occurred within 1 day of the procedure and resolved within 7 days. 6  In this study, bronchial thermoplasty was found to significantly improve quality of life, as well as reduce the rate of severe exacerbations by 32%. 6  Patients who underwent the procedure also reported fewer adverse respiratory effects, fewer days lost from work, school, or other activities due to asthma, and an 84% risk reduction in emergency department visits. 6

Long-term (5-year) follow-up studies have been conducted for patients in both  the AIR  and  the AIR-2  trials. In patients who underwent bronchial thermoplasty in either study, the rate of adverse respiratory effects remained stable in years 2 to 5 following the procedure, with no increase in hospitalizations or emergency department visits. 7,12  Additionally, FEV1 remained stable throughout the 5-year follow-up period. 7,12  This finding was maintained in patients enrolled in the AIR-2 trial despite decreased use of daily ICS. 7

Bronchial thermoplasty is an important addition to the asthma treatment armamentarium. 7  This treatment is currently approved for individuals with severe persistent asthma who remain uncontrolled despite the use of an ICS and LABA. Several clinical trials with long-term follow-up have now demonstrated its safety and ability to improve quality of life in patients with severe asthma, such as Mr. T.

Severe asthma can be a challenge to manage. Patients with this condition require an extensive workup, but there are several treatments currently available to help manage these patients, and new treatments are continuing to emerge. Managing severe asthma thus requires knowledge of the options available as well as consideration of a patient's personal situation-both in terms of disease phenotype and individual preference. In this case, the patient expressed a strong desire to not add any additional medications to his asthma regimen, which explained the rationale for choosing to treat with bronchial thermoplasty. Personalized treatment necessitates exploring which of the available or emerging options is best for each individual patient.

Case Study Conclusion: Cough That Won't Quit

The little child shown in Figure \(\PageIndex{1}\) seems to be enjoying the air coming out of a humidifier. Inhaling the moist air from a humidifier or steamy shower can feel particularly good if you have a respiratory system infection, such as bronchitis. The moist air helps to loosen and thin mucus in the respiratory system, allowing you to breathe easier.

At the beginning of this chapter, you learned about Sacheen, who developed acute bronchitis after getting a cold. She had a worsening cough, sore throat due to coughing, and chest congestion. She was also coughing up thick mucus.

Acute bronchitis usually occurs after a cold or flu, usually due to the same viruses that cause cold or flu. Because bronchitis is not usually caused by bacteria (although it can be), antibiotics are not an effective treatment in most cases.

Bronchitis affects the bronchial tubes, which, as you have learned, are air passages in the lower respiratory tract. The main bronchi branch off of the trachea and then branch into smaller bronchi and then bronchioles. In bronchitis, the walls of the bronchi become inflamed, which makes them narrower. Also, there is excessive production of mucus in the bronchi, which further narrows the pathway through which can flow. Figure \(\PageIndex{2}\) shows how bronchitis affects the bronchial tubes.

The function of mucus is to trap pathogens and other potentially dangerous particles that enter the respiratory system from the air. However, when too much mucus is produced in response to an infection (as in the case of bronchitis), it can interfere with normal airflow. The body responds by coughing as it tries to rid itself of the pathogen-laden mucus.

The treatment for most cases of bronchitis involves thinning and loosening the mucus so that it can be effectively coughed out of the airways. This can be done by drinking plenty of fluids, using humidifiers or steam, and in some cases, using over-the-counter medications such as expectorants that are found in some cough medicines. This is why Dr. Tsosie recommended some of these treatments to Sacheen and also warned against using cough suppressants. Cough suppressants work on the nervous system to suppress the cough reflex. When a patient has a “productive” cough—i.e. they are coughing up mucus—doctors generally advise them to not take cough suppressants so that they can cough the mucus out of their bodies.

When Dr. Tsosie was examining Sacheen, she used a pulse oximeter to measure the oxygen level in her blood. Why did she do this? As you have learned, the bronchial tubes branch into bronchioles, which ultimately branch into the alveoli of the lungs. The alveoli are where gas exchange occurs between the air and the blood to take in oxygen and remove carbon dioxide and other wastes. By checking Sacheen’s blood oxygen level, Dr. Tsosie was making sure that her clogged airways were not impacting her level of much-needed oxygen.

Sacheen has acute bronchitis, but you may recall that chronic bronchitis was discussed earlier in this chapter as a term that describes the symptoms of chronic obstructive pulmonary disease (COPD). COPD is often due to tobacco smoking and causes damage to the walls of the alveoli, whereas acute bronchitis typically occurs after a cold or flu and involves inflammation and mucus build-up in the bronchial tubes. As implied by the difference in their names, chronic bronchitis is an ongoing, long-term condition, while acute bronchitis is likely to resolve relatively quickly with proper rest and treatment.

However, Sacheen smokes cigarettes, so she is more likely to develop chronic respiratory conditions such as COPD. As you have learned, smoking damages the respiratory system as well as many other systems of the body. Smoking increases the risk of respiratory infections, including bronchitis and flu, due to its damaging effects on the respiratory and immune systems. Dr. Tsosie strongly encouraged Sacheen to quit smoking, not only so that her acute bronchitis resolves, but so that she can avoid future infections and other negative health outcomes associated with smoking, including COPD and lung cancer.

As you have learned in this chapter, the respiratory system is critical to carry out the gas exchange necessary for life’s functions and to protect the body from pathogens and other potentially harmful substances in the air. But this ability to interface with the outside air has a cost. The respiratory system is prone to infections, as well as damage and other negative effects from allergens, mold, air pollution, and cigarette smoke. Although exposure to most of these things cannot be avoided, not smoking is an important step you can take to protect this organ system—as well as many other systems of your body.

Chapter Summary

In this chapter, you learned about the respiratory system. Specifically, you learned that:

• Respiration is the process in which oxygen moves from the outside air into the body and carbon dioxide and other waste gases move from inside the body into the outside air. It involves two subsidiary processes: ventilation and gas exchange.
• The upper respiratory tract includes the nasal cavity, pharynx, and larynx. All of these organs are involved in conduction or the movement of air into and out of the body. Incoming air is also cleaned, humidified, and warmed as it passes through the upper respiratory tract. The larynx is also called the voice box because it contains the vocal cords, which are needed to produce vocal sounds.
• The lower respiratory tract includes the trachea, bronchi and bronchioles, and the lungs. The trachea, bronchi, and bronchioles are involved in conduction. Gas exchange takes place only in the lungs, which are the largest organs of the respiratory tract. Lung tissue consists mainly of tiny air sacs called alveoli, which is where gas exchange takes place between the air in the alveoli and the blood in capillaries surrounding them.
• The respiratory system protects itself from potentially harmful substances in the air by the mucociliary escalator. This includes mucus-producing cells, which trap particles and pathogens in the incoming air. It also includes tiny hair-like cilia that continually move to sweep the mucus and trapped debris away from the lungs and toward the outside of the body.
• The level of carbon dioxide in the blood is monitored by cells in the brain. If the level becomes too high, it triggers a faster rate of breathing, which lowers the level to the normal range. The opposite occurs if the level becomes too low. The respiratory system exchanges gases with the outside air, but it needs the cardiovascular system to carry the gases to and from cells throughout the body.
• Breathing is one of the few vital bodily functions that can be controlled consciously as well as unconsciously. Conscious control of breathing is common in many activities, including swimming and singing. However, there are limits on the conscious control of breathing. If you try to hold your breath, for example, you will soon have an irrepressible urge to breathe.
• Unconscious breathing is controlled by respiratory centers in the medulla and pons of the brainstem. They respond to variations in blood pH by either increasing or decreasing the rate of breathing as needed to return the pH level to the normal range.
• Nasal breathing is generally considered to be superior to mouth breathing because it does a better job of filtering, warming, and moistening incoming air. It also results in slower emptying of the lungs, which allows more oxygen to be extracted from the air.
• Gas exchange in the lungs takes place in alveoli. The pulmonary artery carries deoxygenated blood from the heart to the lungs, where it travels through pulmonary capillaries, picking up oxygen, and releasing carbon dioxide. The oxygenated blood then leaves the lungs through pulmonary veins.
• Gas exchange occurs by diffusion across cell membranes. Gas molecules naturally move down a concentration gradient from an area of higher concentration to an area of lower concentration. This is a passive process that requires no energy.
• Gas exchange by diffusion depends on the large surface area provided by the hundreds of millions of alveoli in the lungs. It also depends on a steep concentration gradient for oxygen and carbon dioxide. This gradient is maintained by continuous blood flow and constant breathing.
• Asthma is a chronic inflammatory disease of the airways in the lungs, in which the airways periodically become inflamed. This causes swelling and narrowing of the airways, often with excessive mucus production, leading to difficulty breathing and other symptoms. Asthma is thought to be caused by a combination of genetic and environmental factors. Asthma attacks are triggered by allergens, air pollution, or other factors.
• Pneumonia is a common inflammatory disease of the respiratory tract in which inflammation affects primarily the alveoli, which become filled with fluid that inhibits gas exchange. Most cases of pneumonia are caused by viral or bacterial infections. Vaccines are available to prevent pneumonia; treatment often includes prescription antibiotics.
• Chronic obstructive pulmonary disease (COPD) is a lung disease characterized by chronic poor airflow, which causes shortness of breath and a productive cough. It is caused most often by tobacco smoking, which leads to the breakdown of connective tissues in the lungs. Alveoli are reduced in number and elasticity, making it impossible to fully exhale air from the lungs. There is no cure for COPD, but stopping smoking may reduce the rate at which COPD worsens.
• Lung cancer is a malignant tumor characterized by uncontrolled cell growth in tissues of the lung. It results from accumulated DNA damage, most often caused by tobacco smoking. Lung cancer is typically diagnosed late, so most cases cannot be cured. It may be treated with surgery, chemotherapy, and/or radiation therapy.
• The major health risk of smoking is cancer of the lungs. Smoking also increases the risk of many other types of cancer. Tobacco smoke contains dozens of chemicals that are known carcinogens.
• Smoking is the primary cause of COPD. Chemicals such as carbon monoxide and cyanide in tobacco smoke reduce the elasticity of alveoli so the lungs can no longer fully exhale air.
• Smoking damages the cardiovascular system and increases the risk of high blood pressure, blood clots, heart attack, and stroke. Smoking also has a negative impact on levels of blood lipids.
• A wide diversity of additional adverse health effects are attributable to smoking, such as erectile dysfunction, female infertility, and slow wound healing.

• Category Bronchitis

Acute bronchitis is a common respiratory condition that affects millions of people worldwide. It is characterized by an inflammation of the bronchial tubes, which are responsible for carrying air to and from the lungs. In this case study, we will explore the symptoms, diagnosis, and treatment options for a patient with acute bronchitis. By examining the unique circumstances of this individual, we can gain a deeper understanding of the complexities of this condition and the approaches that healthcare professionals employ to address it effectively.

What You'll Learn

What are the symptoms and signs of acute bronchitis as described in the case study, what factors or circumstances may have contributed to the patient developing acute bronchitis, how was the patient diagnosed with acute bronchitis, what treatment options were considered or recommended for the patient's acute bronchitis, has the patient shown any improvement or progression of their symptoms since the diagnosis.

Acute bronchitis is a common respiratory condition characterized by inflammation of the bronchial tubes, which carry air to and from the lungs. It is typically caused by a viral infection and is often preceded by an upper respiratory tract infection, such as the common cold.

In the case study, the symptoms and signs of acute bronchitis can be observed and described. These may include:

Cough: A persistent cough is one of the hallmark symptoms of acute bronchitis. The cough is usually non-productive in the early stages but may later produce phlegm or mucus. The cough can be quite severe and is often worse at night or upon waking up in the morning. It may last for several weeks.

Wheezing: Wheezing is a whistling sound that occurs when air is forced through narrowed airways. It is commonly heard during expiration and can be a sign of bronchial inflammation and constriction. If accompanied by shortness of breath, it may indicate a more severe form of bronchitis or the development of asthma.

Shortness of breath: Some individuals with acute bronchitis may experience shortness of breath or difficulty breathing, especially with physical exertion. This symptom may be more pronounced in individuals who already have underlying respiratory conditions, such as asthma or chronic obstructive pulmonary disease (COPD).

Chest discomfort: Chest discomfort or tightness may be present in some individuals with acute bronchitis. This can be attributed to the inflammation and irritation of the bronchial tubes, leading to a feeling of pressure or heaviness in the chest.

Fever and fatigue: While not all individuals with acute bronchitis will experience fever, it is a possible symptom. Fever is usually low-grade, ranging from 100 to 101 degrees Fahrenheit. Fatigue and general malaise may also accompany acute bronchitis, as the body fights off the viral infection.

It is important to note that these symptoms can vary from person to person, and some individuals may experience a milder form of acute bronchitis with fewer or less severe symptoms. However, in the case study, the presence of a persistent cough, wheezing, shortness of breath, chest discomfort, and other associated symptoms suggests a more significant respiratory inflammation.

In conclusion, the symptoms and signs of acute bronchitis as described in the case study include a persistent cough, wheezing, shortness of breath, chest discomfort, and potentially fever and fatigue. These symptoms can vary in severity and may last for several weeks. It is important for individuals experiencing these symptoms to seek medical attention to receive an accurate diagnosis and appropriate treatment.

How Serious is Asthmatic Bronchitis? Understanding the Severity of this Respiratory Condition

Acute bronchitis is a respiratory condition that involves inflammation of the bronchial tubes, which are responsible for carrying air to the lungs. It is commonly caused by viral infections, although bacterial infections and environmental factors can also play a role. In this article, we will explore the various factors and circumstances that may contribute to a person developing acute bronchitis.

• Viral Infections: The most common cause of acute bronchitis is viral infections, such as the common cold or influenza. These viruses can easily spread from person to person through coughing, sneezing, or close contact. When the virus enters the body, it can attack the cells lining the bronchial tubes, leading to inflammation and increased production of mucus. This combination of inflammation and excess mucus causes the characteristic symptoms of acute bronchitis, including coughing, wheezing, and shortness of breath.
• Bacterial Infections: Although less common than viral infections, bacterial infections can also contribute to the development of acute bronchitis. Bacteria such as Streptococcus pneumoniae or Haemophilus influenzae can infect the respiratory tract and cause inflammation of the bronchial tubes. Bacterial bronchitis often occurs as a secondary infection following a viral infection.
• Smoking: Smoking is a significant risk factor for developing acute bronchitis. The toxins in cigarette smoke irritate the airways and lungs, making them more susceptible to infection. Smoking can also impair the ability of the lungs to clear mucus, leading to a buildup of mucus in the bronchial tubes. This mucus provides an ideal environment for bacteria to grow and cause infection.
• Environmental Factors: Exposure to certain environmental factors can increase the risk of developing acute bronchitis. These may include air pollution, chemical irritants, and dust particles. When these substances are inhaled, they can irritate the bronchial tubes and trigger inflammation. For example, people who work in industries such as mining or construction, where they are regularly exposed to dust or chemical fumes, may be at a higher risk of developing acute bronchitis.
• Weakened Immune System: A weakened immune system can make a person more susceptible to infections, including those that can cause acute bronchitis. This can be due to various factors, such as chronic illness, malnutrition, or certain medications that suppress the immune system. People with compromised immune systems, such as those with HIV, cancer, or undergoing chemotherapy, may be at a higher risk of developing acute bronchitis.

In conclusion, several factors and circumstances can contribute to the development of acute bronchitis. Viral infections, bacterial infections, smoking, environmental factors, and a weakened immune system are all potential risk factors. By understanding these factors and taking appropriate precautions, such as practicing good hygiene, avoiding exposure to irritants, and quitting smoking, individuals can reduce their risk of developing acute bronchitis. However, if symptoms persist or worsen, it is important to seek medical attention for a proper diagnosis and treatment.

Is Cipro an Effective Treatment for Bronchitis? Expert Opinion Revealed

Acute bronchitis is a condition that affects the airways leading to the lungs. It is characterized by inflammation of the bronchial tubes, which results in symptoms such as coughing, chest discomfort, and shortness of breath. Diagnosis of acute bronchitis involves a combination of medical history, physical examination, and additional tests if necessary.

When a patient presents with symptoms consistent with acute bronchitis, the healthcare provider will begin by taking a detailed medical history. This includes asking about the onset and duration of symptoms, any recent respiratory infections or exposures, and any underlying medical conditions that may contribute to the development of bronchitis. It is also important to ask about any smoking history, as acute bronchitis is more common in individuals who smoke.

After obtaining the medical history, the healthcare provider will perform a physical examination. They will listen to the patient's lungs using a stethoscope, looking for any abnormal breath sounds such as wheezing or crackles, which may indicate inflammation or fluid in the airways. The presence of fever, increased heart rate, and respiratory distress may also be noted during the examination.

In most cases, the combination of a detailed medical history and physical examination is sufficient to diagnose acute bronchitis. However, in some cases, additional tests may be necessary to rule out other possible causes of the symptoms. These tests may include a chest X-ray or a sputum culture.

A chest X-ray can help the healthcare provider visualize the lungs and rule out any other conditions, such as pneumonia or lung cancer, that may present with similar symptoms to acute bronchitis. It can also help identify any complications of bronchitis, such as pneumonia or signs of chronic obstructive pulmonary disease (COPD).

A sputum culture involves collecting a sample of the patient's sputum, which is the mucus that is coughed up from the lungs. This sample is then sent to a laboratory for testing to identify any bacterial or fungal infections that may be causing the bronchitis. This test is not routinely performed in all cases of acute bronchitis but may be considered if the symptoms are severe or if the patient does not respond to initial treatment.

Overall, the diagnosis of acute bronchitis is primarily based on a thorough medical history and physical examination. Additional tests such as chest X-ray or sputum culture may be done in certain cases to rule out other causes or complications. It is worth noting that acute bronchitis is typically a self-limited condition that resolves without specific treatment, and therefore, the focus of diagnosis is mainly on ruling out more serious underlying conditions.

Is it necessary to stay home if I have bronchitis? Understanding when to take a break for better recovery

Acute bronchitis is a common respiratory condition characterized by the inflammation of the bronchial tubes. It is typically caused by a viral infection and can result in symptoms such as coughing, chest congestion, and difficulty breathing. When patients present with acute bronchitis, healthcare providers consider several treatment options to alleviate symptoms and promote recovery.

• Symptomatic treatment: The primary approach to managing acute bronchitis is symptomatic treatment. This involves addressing the symptoms experienced by the patient, such as coughing and congestion. Over-the-counter medications like cough suppressants or expectorants may be recommended to relieve coughing and help clear mucus from the airways. Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or acetaminophen can help reduce pain and fever associated with bronchitis.
• Rest and hydration: Adequate rest is essential to allow the body to recover from acute bronchitis. Patients are advised to take time off work or school to allow the immune system to fight off the infection. Staying hydrated is also important as it helps thin out mucus and makes it easier to expel. Drinking plenty of fluids, such as water, herbal teas, and warm soups, can provide relief and promote recovery.
• Steam inhalation: Steam inhalation can help soothe the airways and relieve congestion. Patients are advised to lean over a bowl of hot water and cover their heads with a towel to trap the steam. Adding a few drops of essential oils, such as eucalyptus or peppermint, can further enhance the therapeutic effects. However, caution should be exercised to avoid burns.
• Bronchodilators: In some cases, healthcare providers may prescribe bronchodilators to patients with acute bronchitis. Bronchodilators are medications that help relax the muscles around the bronchial tubes, making it easier to breathe. They are commonly used in patients who experience severe wheezing or shortness of breath. β2-agonists, such as albuterol, are a common class of bronchodilators prescribed for acute bronchitis.
• Antibiotics: Antibiotics are not routinely recommended for the treatment of acute bronchitis. Since most cases are caused by viruses, antibiotics are ineffective and unnecessary. However, in rare cases where the bronchitis is caused by a bacterial infection or if there are underlying health conditions that increase the risk of complications, such as chronic obstructive pulmonary disease (COPD), antibiotics may be considered.

It is important for patients with acute bronchitis to monitor their symptoms and seek medical attention if they worsen or persist beyond a few weeks. In some cases, acute bronchitis can progress to a more severe respiratory infection, such as pneumonia. Patients should also follow proper respiratory hygiene practices, such as covering their mouth and nose when coughing or sneezing, to prevent the spread of the infection to others.

In summary, treatment options for acute bronchitis focus on relieving symptoms and supporting the body's natural healing process. Symptomatic treatment, rest, hydration, steam inhalation, and bronchodilators are commonly recommended. Antibiotics are generally not prescribed unless there is evidence of a bacterial infection or underlying health conditions. With proper management, most cases of acute bronchitis resolve within a few weeks, and patients can return to their normal activities.

Exploring the Symptoms, Diagnosis, and Treatment Options for Acute Bronchitis: Insights from BMJ

Diagnosing a medical condition is the first step towards finding appropriate treatments and interventions. Once a diagnosis has been made, it is crucial to assess whether the patient has shown any improvement or progression of their symptoms since the diagnosis. Monitoring the patient's progress can help healthcare providers evaluate the effectiveness of the chosen treatments and make adjustments as needed.

There are several ways to assess the improvement or progression of symptoms in a patient. These methods can include subjective reports from the patient, objective measurements, and follow-up visits with healthcare providers. Let's explore some examples of how these methods can be used to evaluate a patient's progress.

Subjective reports from the patient are an essential tool for assessing symptom improvement or progression. The patient's experience and perception of their symptoms are invaluable in understanding how the condition is affecting their daily life. Patients can provide information about changes in pain levels, activity limitations, mood, and overall quality of life. These reports can be collected through regular check-ins, questionnaires, or personal journals.

Objective measurements are another important aspect of monitoring a patient's progress. These measurements can include physical examinations, laboratory tests, imaging studies, or other diagnostic tools. For example, if a patient was diagnosed with arthritis, their healthcare provider may use X-rays to assess changes in joint inflammation or deterioration over time. Similarly, a patient with diabetes may have their blood sugar levels monitored to evaluate the effectiveness of their medication and lifestyle modifications.

Follow-up visits with healthcare providers allow for ongoing evaluation and adjustments to the treatment plan. During these visits, healthcare providers can review the patient's progress, discuss any changes in symptoms, and address any concerns or questions. They may also recommend additional interventions, such as physical therapy, medication adjustments, or other treatments, based on the patient's response to the initial treatment plan.

Let's consider a specific example to illustrate this process. Imagine a patient who was diagnosed with depression. At the initial diagnosis, the patient reported feelings of sadness, loss of interest in activities, and changes in appetite and sleep patterns. They were started on an antidepressant medication and referred to therapy. Over the next few months, the patient attended regular therapy sessions and took their medication as prescribed. During follow-up visits, the patient reported a decrease in feelings of sadness and an improvement in their ability to engage in previously enjoyed activities. Based on these reports, the healthcare provider may consider the treatment successful.

In contrast, if the patient had reported no improvement or even a worsening of symptoms, their healthcare provider would reassess the treatment plan. They may consider adjusting the medication dosage, adding additional therapies, or exploring other treatment options altogether. Close monitoring of the patient's progress and symptomatology is vital in these situations to ensure that the patient receives the most appropriate care.

In conclusion, monitoring a patient's progress and evaluating the improvement or progression of their symptoms is crucial after a diagnosis has been made. This assessment can be done through subjective patient reports, objective measurements, and follow-up visits with healthcare providers. By regularly evaluating the patient's response to treatment, healthcare providers can make informed decisions about adjusting the treatment plan and ensuring the best possible outcomes for the patient's health.

Frequently asked questions.

Acute bronchitis is a temporary inflammation of the bronchial tubes, which are the airways that carry air to the lungs. It is usually caused by a viral infection and commonly occurs alongside a cold or flu.

The most common symptoms of acute bronchitis include a cough that may produce mucus, chest congestion, wheezing, shortness of breath, and a low-grade fever. Other symptoms may include a sore throat, headache, and body aches.

Acute bronchitis is usually a self-limiting condition that resolves on its own within a few weeks. Treatment primarily focuses on managing symptoms and providing relief. This may include over-the-counter medications to ease cough and congestion, drinking plenty of fluids to stay hydrated, getting plenty of rest, and using a humidifier or steam inhalation to help soothe the airways. In some cases, your healthcare provider may prescribe antiviral medications if the cause of acute bronchitis is determined to be viral. Antibiotics are typically not recommended unless there is evidence of a bacterial infection. It is important to rest and avoid exposure to irritants such as cigarette smoke, as this can worsen symptoms.
