34. Fellows’ Case Files: The Ohio State University College of Medicine

Welcome back to Pulm PEEPs Fellows’ Case Files series. We are traveling to the midwest to visit The Ohio State University College of Medicine and hear about another great pulmonary case.

Patient Presentation

Key Learning Points

**Spoilers Ahead** If you want to think through the case on your own we advise listening to the episode first before looking at these points.

The three most common causes of cough in adults in the USA are cough variant asthma, GERD, and post-nasal drip
A post-viral cough can last for 8-12 weeks and still be within normal
Sinus symptoms in a chronic cough can just be sinusitis and post-nasal drip, but should consider eosinophilic granulomatosis with polyangiitis (EGPA), aspirin exacerbated respiratory disease (AERD), cystic fibrosis, or ciliary dyskinesia.
Examination of a wheeze
- Fixed sound vs variable
- Pitch: larger central airways vs lower peripheral airways
- Is it throughout the cycle or at a certain phase?
- Ask the patient to cough before listening and ask them to breathe out through their mouth
Approach to eosinophilia in a patient with cough and dyspnea
- Multi-system involvement vs lungs
  - Multi-system involvement
    - Vasculitis
    - Parasitic infection
    - Hematologic malignancy
    - Medication side effect
    - Primary hypereosinophilic syndromes
  - Within the lungs:
    - Parenchymal disease
      - Loeffler’s syndrome
      - Eosinophilic pneumonia
    - Airway disease
      - Asthma
      - ABPA
If you have a high suspicion for airways disease, PFTs should be requested with bronchodilator testing regardless of the degree of obstruction on baseline spirometry
Asthma alone should not cause ground glass opacities, so if see these in a patient with asthma we think about:
- Infection, especially atypical infections
- EGPA
- Vasculitis with DAH
- ABPA
- Hypogammaglobulinemia or other immunodeficiency
EGPA diagnosis
- ANCA testing is only positive in 60% of patients with EGPA so a negative test doesn’t rule it out by any means
- It is easiest to make a diagnosis when there is a clear small vessel manifestation
  - Alveolar hemorrhage
  - Mononeuritis multiplex
  - Glomerulonephritis
- Many patients with asthma, nasal polyposis, and high peripheral eosinophilia have EGPA but don’t have a clear small vessel feature of vasculitis or a positive ANCA
  - These patients typically have eosiniophilia a lot higher than when thinking about allergic phenotype asthma alone. As a rule of thumb, at least an absolute eosinophil count > 1000

Radiology Rounds 29: Primary Ciliary Dyskinesia

We are back with our first #RadiologyRounds of 2023!

While chronic lung infections and infertility are overlapping symptoms for CF and Primary Ciliary Dyskinesia, the history of neonatal respiratory syndrome, ear infections and lower lobe bronchiectasis are most consistent with PCD

In up to 50% of people with PCD, you can get complete reversal of thoracic and abdominal organs. In this film you can see the heart in the right hemithorax, the gastric bubble on the right with the liver on the left resulting in elevation of the left hemidiaphragm

In patients with clinical symptoms and two decreased levels of nasal nitric oxide these findings suggest a PCD diagnosis but evaluation of the cilia structure and function as well as genetic testing are other diagnostic evaluations to confirm a diagnosis of PCD

Primary ciliary dyskinesia is a autosomal recessive disorder that results in motile ciliary dysfunction and clinical manifestations can vary depending on which organs are involved

Radiology Rounds 27: Mosaic Attenuation

Time for Tuesday #RadiologyRounds!

A 40-year-old patient s/p allogeneic stem cell transplant for AML 6 months prior presents with progressive dyspnea. The exam is unrevealing and imaging is obtained.

The patient’s CT reveals mosaic attenuation. Mosiac attenuation is a pattern of scattered regions of the lung with differing densities. The abnormal portions can be those that appear white or black.

Tip: Inspiratory and expiratory films can help identify the cause!

The patient had PFTs that showed severe obstruction, and significant change from PFTs prior to the stem cell transplant. Inspiratory and expiratory CT confirmed significant areas of gas trapping. She was diagnosed with bronchiolitis obliterans secondary to chronic GVHD

Radiology Rounds 19: Sarcoidosis Stages

It is Tuesday and we have another Radiology Rounds we can’t wait to share with you. Follow along and see if you select the right answer as we go through different presentations of sarcoidosis and pick your answer! What stage is it?!

A middle-aged man presents to you after he was found to have hilar adenopathy on a routine chest x-ray.

A middle-age man presents with dyspnea on exertion, night sweats and weight loss. You see evidence of bilateral apical disease, and fibrosis with evidence of honeycombing on chest CT.

A young woman presents with dyspnea on exertion and was found to have hilar adenopathy with parenchymal disease.

An elderly man presents with dyspnea on exertion and was found to have nodular parenchymal disease without extensive lymphadenopathy.

19. Severe COPD and Lung Volume Reduction

We are extremely excited for the third and final installment in our Pulm PEEPs and ATS Clinical Problems Assembly collaborative series on COPD. Today, we are joined by Drs. Jessica Bon, Michael Lester, and Niru Putcha to discuss severe COPD management and the role of lung volume reduction procedures. If you missed the first two parts of our series, make sure to check out episode 1 on COPD diagnosis and initial management, and episode 2 on COPD exacerbations.

Meet our Guests

Jessica Bon is an Associate Professor of Medicine at the University of Pittsburgh School of Medicine where she is also the Program Director for the Pulmonary and Critical Care Medicine Fellowship. Her research and clinical interests focus on lung disease progression in COPD and she manages patients with difficult-to-treat and severe COPD and evaluates patients for lung volume reduction surgery. Jessica was the chair of the ATS Clinical Problems Assembly Programming Committee from 2021 – 2022.

Michael Lester is an Assistant Professor of Medicine at Vanderbilt University Medical Center. Michael’s interests span both pulmonary and critical care medicine. He specializes in patients with advanced COPD and evaluation for bronchoscopic lung volume reduction surgery.

Niru Putcha is an Associate Professor of Medicine at Johns Hopkins School of Medicine and is an integral member and mentor in the Obstructive Lung Disease Group. Her research and clinical interests focus on the role of comorbidities on clinical outcomes in individuals with COPD. She also manages patients with difficult-to-treat and severe COPD and evaluates patients for lung volume reduction surgery. Niru is also the new chair of the ATS Clinical Problems Assembly Programming Committee.

Key Learning Points

Patients with advanced COPD should also be considered for lung transplantation. We will have an episode on lung transplant coming up soon!

Radiology Rounds 12: Centrilobular Emphysema

This week on #RadiologyRounds we continue our series on COPD. Make sure to listen to all our episodes made in collaboration with the ATS Clinical Problems Assembly.

The CT shows moderate to severe centrilobular emphysema. These different patterns of emphysematous changes on CT can be related to the underlying driver of the disease and to symptom and disease severity.

In terms of follow-up, would you test this patient for alpha 1 anti-trypsin deficiency?

Current GOLD guidelines recommend that everyone with COPD, regardless of age or ethnicity should be tested for alpha 1 anti-trypsin deficiency.
