Adult Onset Asthma
This case study takes place in an Urgent Care (UC). The patient that self presented to the UC consist of the following given scenario:
A 25-year-old previously well woman presents to your office with complaints of episodic shortness of breath and chest tightness. She has had the symptoms on and off for about 2 years but states that they have worsened lately, occurring two or three times a month. She notes that the symptoms are worse during the spring months. She has no exercise-induced or nocturnal symptoms. The family history is notable for a father with asthma. She is single and works as an administrative assistant in a high-tech firm. She lives with a roommate, who moved in approximately 2 months ago. The roommate has a cat. The patient smokes occasionally when out with friends and drinks socially but has no history of illicit drug use.
Pertinent PE findings include the following: VS 115/80 HR 84 RR 22 T 98.6 O2 sat 95% room air. Pertinent physical examination is notable for mild end-expiratory wheezing. The rest of the PE findings are unremarkable.

PRIMARY DIAGNOSIS: Adult Onset Asthma
The patient in this case study presented with adult onset asthma. Adult onset asthma is noted during physical examination with symptoms of end-expiratory wheezing and slightly tachypneic with respiration of 22. Although SaO2 is 95%, it is noted to be low normal for a fairly healthy 25-year-old. Subjective information includes chest tightness and shortness of breath. These symptoms demonstrate bronchial hyperresponsiveness and strongly suggest a diagnosis of adult onset asthma. The roommate’s cat may be a trigger or allergen for this specific patient. Exposure to allergens can initiate a cascade of cellular activation events in the airway leading to acute and chronic inflammatory response resulting in the release of cytokines and other mediators (Asthma and Allergy Foundation of America. 2020). Mediators cause increase airway inflammation, air way hyperresponsiveness and asthma symptoms. The cascading events can result in permanent changes in both structure and function of the airway.
Asthma is a common pulmonary condition defined by airway inflammation that causes inflammation to the respiratory tubes, tightening of respiratory smooth muscles, and episodes of brochoconstriction (Brashers, V., & Rote, N. 2018). The airways narrow resulting in an increase in resistance that manifest as episodes of coughing, shortness of breath, and wheezing (Brashers, V., & Rote, N. 2018). Airway capillaries may dilate and leak, increasing secretions, which in turn causes edema and impairs mucus clearance (Brashers, V., & Rote, N. 2018). The increase in mucus can cause plugs that block the airway. It can affect the trachea, bronchi, and bronchioles. In many healthy individuals the airway does not contribute to significant changes to airflow resistance. Loss of the epithelia’s barrier function allows allergens to penetrate, causing the airways to become hyperresponsiveness (Brashers, V., & Rote, N. 2018). The extent of inflammation along with the individual’s immunologic response will account for the level of hyperresponsiveness.
Acute Coronary Syndrome (ACS) is a term that encompasses many cardiac diagnoses, which include STEMI, NONSTEMI, unstable angina, cardiac arrhythmia, and cardiac tamponade (Uptodate, 2020). These cardiac diseases can reduce blood flow to the heart causing changes in how the heart works. These changes can predispose individuals to heart attacks or even sudden death. These symptoms include chest pain, shortness of breath, nausea, vomit, dizziness, lightheadedness, fatigues, and sudden sweating (Uptodate, 2020). Many times, dyspnea might be the only presentation, especially in females, older adult, and diabetics. In this case, ruling out ACS is imperative. Heart failure can also mimic symptoms of asthma, however, this patient is too young and healthy to suspect heart failure at this time.
2. Pulmonary Embolism
Pulmonary Embolism (PE) occurs when there is a blockage in the pulmonary arteries by a blood clot that usually forms in other parts of the body, dislodges and travels upwards (Wedo, B., 2019). It usually forms in the deep veins of the upper and lower extremities. Symptoms can be very similar to that of asthma; symptoms include dyspnea at rest, tachypnea, anxiety, and pleuritic chest pain (Wedo, B., 2019). Symptoms can present acute or chronic. Diagnosis can be suspected if patient reports prolonged immobilization such as in prolonged bedrest due to surgery or illness or prolonged sitting during traveling, trauma to one of the extremities, bleeding abnormalities, pregnancy, use of birth control, or certain cancers. PE is not the proper diagnosis for this patient as patient denies recent immobilization as she continues to work as schedule, recent travel as she denies taking any vacations, denies being sexually active at this time with no need to take contraception, and denies any medical history. Physical examination did not observe edema, redness, tenderness to any of the 4 extremities. Chronic obstruction pulmonary disease can mimic symptoms of asthma; however, this patient does not seem to suffer from progressively worsening lung disease, cough and trouble breathing. The patient reports episode of shortness of breath and chest pain, increasing in frequency. Patient denies being a heavy smoker and physical assessment did not find signs of barrel chest.
An electrocardiogram (EKG) is a noninvasive, painless diagnostic procedure that measures electrical signals in the heart. It can detect irregular heart rhythms and identify causes of chest pain, shortness of breath, dizziness and fainting. The test consists of having small electrodes attached to specific areas in the chest and extremities while a technician records the signal. The procedure can take a few minutes, typically less than 10. This test can rule out emergent situations such as a ST-Elevation Myocardial Infarction (Papadakis, M & McPhee, S. 2020). Individuals presenting with chest pain or epigastric pain should have an EKG completed to rule out STEMI. This test can also help identify abnormal rhythms such as Atrial fibrillation.
2. Chest Radiography
Chest radiography (CXR) is another noninvasive diagnostic tool that is used to identify conditions of the lungs such as pneumonia, pulmonary edema, pulmonary effusion, lung mases or nodules (Papadakis, M & McPhee, S. 2020). It uses small amount of radiation to create an image of the structures within the chest as a beam of radiation passes through the body. As a result, a black and white image is created. Asthma is not diagnosed using a radiographic image, however, it can be very useful in ruling out other lung diseases.
3. Ancillary Laboratory Tests
A. Cardiac Panel- A cardiac panel identifies abnormal cardiac enzymes and cardiac markers. It is useful in identify cardiac emergencies such as STEMI’s. It can be use in conjunction with an EKG to assess the heart condition. A negative cardiac panel rules out a cardiac event.
B. Complete Blood Count – A CBC is important when providing care for a patient reporting shortness of breath. Although a CBC can identify eosinophilic asthma, it can also identify other conditions such as anemia which can cause shortness of breath and fatigue (Papadakis, M & McPhee, S. 2020).
C. Basic Metabolic Panel (BMP) – A BMP can provide information about the body’s fluid and electrolyte balance. Electrolytes, like potassium, play a role in cardiac health. Hyperkalemia and hypokalemia can affect the heartbeats and cause arrythmias. Ruling electrolyte imbalance is necessary.
4. Peak Expiratory Flow- A peak flow is a handheld device that measures how well air flows out the lungs. Peak expiratory flow (PEF) can be an important aspect of asthma management. It can help identify early signs of an asthma attack or when medication is no longer producing optimal results and might require changes. PEF monitoring can establish peak flow variability and quantify asthma severity, can be very useful in new adult onset asthma as baseline condition is crucial (Papadakis, M & McPhee, S. 2020).
Medical management of Adult Onset Asthma generally consists of pharmacological interventions. Medications can generally be divided into two different categories, the reliever and the controller (Papadakis, M & McPhee, S. 2020). Relieving medication act primarily by promoting direct relaxation on bronchial smooth muscles while controlling medication helps to attenuate airway inflammation and are taken daily independent of symptoms. (Papadakis, M & McPhee, S. 2020).
