Chronic Shortness of Breath and Cough case study
“I have been experiencing shortness of breath on exertion and persist cough.”
History of Present Illness: The client, H.B is a 38yo white female presents. She visits the clinic after being admitted to the medical/surgical ward due to shortness of breath on exertion with a persistent cough five days ago. The client reports experiencing similar symptoms six months ago, necessitating a visit to her primary care physician’s (PCP) office. The PCP diagnosed H.B with acute bronchitis. Three medications, including bronchodilators, a short course oral steroid taper, and empiric antibiotics were prescribed to manage the client’s condition. However, the client reports that the treatment plan was ineffective in improving her symptoms. H.B adds that the presented symptoms have worsened gradually in the last six months. She reports losing approximately 20-pound (9 kg) over the last year intentionally. The client denies spelunking, camping, or hunting activities. She also denies coming into contact with sick persons.
Medications: Lisinopril 10 mg once daily taken to lower her blood pressure
Allergies: The client denies being allergic to food medicine, or environmental triggers. She reports being allergic to dust and cats during her childhood. Exposure to these triggers caused asthma exacerbation. However, the client denies experiencing any incident of asthma exacerbation since the age of 12 despite being exposed to dust and cats.

Primary Diagnosis: Acute Pulmonary Histoplasmosis
Based on the patient’s medical history, presented clinical manifestation, physical examination results, and diagnostic test results, the client’s primary diagnosis is acute pulmonary histoplasmosis.
Etiology and Clinical Manifestations
The etiology of histoplasmosis is complicated, making its diagnosis challenging. Pulmonary histoplasmosis is caused by the presence of microconidia of Histoplasma spp. fungus into the lungs (Baker et al., 2020). The mycelial phase is less harmful while in the environment at normal temperature. However, it converts into budding yeast cells upon being exposed to high temperatures over 37 C in the host’s lungs. These changes cause an infection, affecting the lung and the entire respiratory system. In most cases, the fungus is transmitted from the soil to a person’s lungs through inhalation, causing infection. Cases of human-to-human transmission are also common. A person can contract the disease upon coming into contact with an infected individual, chronically harboring yeast-forming colonies. Following initial inoculation, the colonies are viable for years; hence can cause infections. Individuals may have a reactivated infection upon traveling from endemic to non-endemic regions. The infection might occur months to years later following long-term viability.
These infections can be asymptomatic or life-threatening conditions. The severity of the infection significantly depends on the fungal inoculum size or the host’s immunological status (Staffolani et al., 2018). Organic matter enriched with bat or bird supports the growth of Histoplasma spp. Therefore, coming into contact with bat-feces-rich caves raises the risk of infection. Similarly, the inoculation rate is relatively high among pet owners. In this case, H.B traveled outside of Nebraska accompanied by her family members within the last year. Additionally, she keeps two birds as pets. Traveling outside the city and keeping birds increased the risk of contracting this infection.
Acute pulmonary histoplasmosis’ symptoms begin to manifest between 3 to17 days after coming into contact with the fungus. Clinically silent manifestations with ill impacts are common among immunocompetent individuals (Staffolani et al., 2018). The acute stage of this infection is mainly characterized by nonspecific respiratory symptoms such as flu and cough. Upon visiting the clinic, the client reports shortness of breath with exertion and cough, which have persisted for the last six months. Thus, acute pulmonary histoplasmosis qualifies as her primary diagnosis.
Differential diagnosis should be conducted to rule out other conditions with similar symptoms. The potential diagnosis for this client is discussed below from the most to the least likely diagnosis.
Aspiration Pneumonitis and Pneumonia
Aspiration pneumonia is another potential diagnosis for this client. It is an infection of the lungs, which occurs after inhaling other particles, including food, saliva, liquid, or vomit among other foreign objects (Mandell & Niederman, 2019). The inhaled chemicals burn the airways and lungs, causing acute inflammation that leads to lung injuries (Mandell & Niederman, 2019). This condition is characterized by shortness of breath (dyspnea), coughing up blood or pus, wheezing, bad breath, chest pain, or extreme tiredness. Symptoms of aspiration pneumonia manifest shortly after inhaling a foreign object. In some people, symptoms manifest within 2 hours after inhaling a foreign particle (Mandell & Niederman, 2019). The client reports shortness of breath on exertion and cough, qualifying for this diagnosis. However, aspiration pneumonia is ruled out since the client’s cough is not accompanied by blood or pus. Additionally, the client denies other significant symptoms, including wheezing, bad breath, chest pain, and extreme tiredness.
The second differential diagnosis for this client is viral pneumonia, which is mainly caused by influenza, SARS-CoV-2, and respiratory syncytial virus (RSV) (Hu et al., 2021). These viruses also cause colds and the flu. Viral pneumonia represents one-third of total pneumonia cases. In the early stages, viral pneumonia is characterized by influenza symptoms, including dry cough, fever, headache, weakness, and muscle pain (Hu et al., 2021). These symptoms worsen within a day or two. At a late stage, individuals experience increasing cough, muscle pain, and shortness of breath. The client might have viral pneumonia since she reported shortness of breath and cough. Nonetheless, viral pneumonia is ruled out since the client’s condition has persisted over the last six months.
Lastly, the client is diagnosed with chlamydial pneumonia, which is caused by C. pneumoniae that also causes bronchitis and lung infection. The risk of developing laryngitis is relatively high among individuals with pneumonia caused by C. pneumoniae and those with pneumonia caused by other types of bacterial pneumonia. This condition is characterized by various clinical manifestations, including shortness of breath, coughing, chest pain due to coughing, stuffy or runny nose, low-grade fever, fatigue, hoarseness, headache, or sore throat.
Slowly worsening cough that can last for weeks or months. Symptoms take around 3 to 4 weeks before manifesting following exposure to bacteria. Individuals might experience these symptoms for several weeks. The client qualifies for this diagnosis since she reported shortness of breath with exertion and cough. However, chlamydial pneumonia is ruled out since the client only experiences shortness of breath on exertion. Additionally, the client denies other significant symptoms, including a stuffy or runny nose, low-grade fever, fatigue, hoarseness, headache, and sore throat.
Further evaluation was conducted to confirm the client’s diagnosis.
A CT of the chest: Results indicated a diffuse centrilobular micronodular pattern with no focal consolidation.
Diagnostic bronchoscopy of the lungs: Was conducted to detect rare or atypical infections and the results would be used to rule out the likelihood of malignancy. A fluid with a muddy and cloudy appearance was detected. Cytology indicated Histoplasma capsulatum. No bleeding.
In asymptomatic patients, pulmonary histoplasmosis is self-resolving and no treatment is needed. Nonetheless, treatment is needed in moderate to severely symptomatic cases. In this case, the client should be prescribed itraconazole 200 mg orally twice daily for 6 to 12 weeks, depending on the client’s response. Itraconazole 200 mg was preferred due to its effectiveness in preventing and treating fungal infections (Pappas et al., 2018). A chest x-ray should be conducted regularly to assess the client’s response to the treatment regimen. Additionally, the client should be observed in the future for recurrence following the diagnosis. The client will continue with itraconazole 200 mg orally twice daily if the medication is effective in improving the client’s symptoms and is well-tolerated. However, the client should be administered amphotericin B for at least 2 weeks and a maximum of 1 year if symptoms worsen after using itraconazole 200 mg orally twice daily.
