32. VV-ECMO Roundtable

Posted on January 3, 2023 by Pulm PEEPs

For the first Pulm PEEPs episode of 2023, we are starting off with a bang and a Roundtable discussion about venovenous extracorporeal membrane oxygenation (VV-ECMO). VV-ECMO has been increasing in use in the intensive care unit for patients with severe respiratory failure, especially during the COVID-19 pandemic. We are joined by experts in the field, Cara Agerstrand, Eddy Fan, and Nida Qadir, to discuss the basics of how ECMO works, physiologic goals, when to use ECMO for patients with ARDS, and much more. Let us know your thoughts and stay tuned for more great content in 2023.

Meet Our Guests

Cara Agerstrand is an Associate Professor of Medicine at Columbia University Irving Medical Center / NewYork-Presbyterian Hospital, where she is also the Director of the Medical ECMO Program. She is an international renown ECMO expert and is the current Conference Chair for the Extracorporeal Life Support Organization (or ELSO). Finally, she is a lauded educator and has received the American College of Chest Physicians Distinguished Educator Award.

Eddy Fan is an Associate Professor at the University of Toronto, and the University Health Network / Mount Sinai Hospital. He is also the Director of Critical Research and the Medical Director of the Extracorporeal Life Support Program. He has literally 100s of publications about ARDS, ECMO, and critical care, chairs the ELSO Research Committee, and spearheads multiple international collaborative studies.

Nida Qadir is an Associate Professor at the University of California Los Angeles and is an Associate Director of the MICU, as well as the co-director of the Post-ICU Recovery Clinic. Nida is also on the Critical Care Editorial Board for CHEST and is a highly regarded pulmonary and critical care educator.

Key Learning Points

VV- ECMO Basic Components and Core Physiology

Oxygenation Delivery on VV-ECMO

Carbon Dioxide Removal on VV-ECMO

Flows and Line Pressures on VV-ECMO

ECMO for ARDS

Should be considered after conventional therapies have failed (including ventilator optimization and proning)
Allows for ultra-lung protective ventilation
Lung rest means settings that minimize ventilator-induced lung injury
EOLIA Trial (see below) shows that ECMO can be delivered safely, and likely has a benefit in severe ARDS, although the magnitude of that benefit remains uncertain. A Bayesian re-analysis showed a high likelihood of benefit even if skeptical of ECMO

ECMO For Bridge to Lung Transplant

Allows for patients to maintain gas exchange while awaiting transplant
Ideally done with patient extubated
Can allow for patients to maintain nutrition and mobility while awaiting transplant

30. Fellows’ Case Files: University of Mississippi Medical Center

Posted on November 29, 2022 by Pulm PEEPs

We’re excited to be back with another episode in our Pulm PEEPs Fellows’ Case Files series! This is a particularly exciting case since it is our first episode where some intrepid fellows reached out to us with an interesting case they had encountered. If you have a great case, please let us know and you can follow in their footsteps! Pack your bags, and let’s head to Mississippi to learn about another great pulmonary and critical care case.

Meet our Guests

Meredith Sloan is a pulmonary and critical care fellow at the University of Mississippi. She completed her medical school at the Medical University of South Carolina College of Medicine, and her residency at the University of Mississippi.

Kevin Kinloch is a senior fellow at the University of Mississippi Medical Center where he also completed his internal medicine residency. He completed medical school at Meharry Medical College.

Jessie Harvey is an Associate professor of Medicine at the University of Mississippi and is the Pulmonary and Critical Care Program Director. She is also the Director of the MICU, and has been at MMC since medical school. She is a dedicated educator and leads the POCUS curriculum for IM residents and PCCM fellows

Patient Presentation

A 65-year-old man presented to the ED with worsening hemoptysis over the last several days after a recent lung biopsy. The patient is an active smoker with at least a 50-pack-year history, and he had been having a cough with small-volume hemoptysis. He ultimately had a chest CT that revealed a large LUL mass (10.3 x 6.4 cm). Given this suspicious mass, three days prior to his ED presentation, he was taken for bronchoscopy with BAL, transbronchial biopsies, endobronchial biopsy, EBUS guided TBNA of 11L, along with TBNA, brushing and radial EBUS TBNA of his left upper lobe mass.

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.

Staging procedures for masses

Enough tissue so we can make a diagnosis and do molecular testing
Highest staging when getting your biopsy

POCUS for respiratory failure

Absence of lung slidings
- Especially post procedure
The presence of a new pleural effusion after a procedure could indicate hemothorax
- Hematocrit sign – an echogenic layering of material in an effusion
New B-lines, especially if prior there were only A-lines
- Cardiogenic or non-cardiogenic pulmonary edema, alveolar hemorrhage, or infection
Diaphragmatic function
- Excursion
- Diaphragm thickness

29. Long COVID Roundtable

Posted on November 15, 2022 by Pulm PEEPs

This week on Pulm PEEPs, Dave and Kristina are joined by Jason Maley and Ann Parker, two pulmonary and critical care physicians who are leaders in treating patients with Long COVID, or Post-Acute Sequelae of SARS-CoV-2. Both of them help run the Long COVID clinics at their respective institutions and are part of broader consortiums dedicated to patient care. They also both participate in research to improve outcomes for patients with Long COVID and Post-Intensive Care Syndrome. In this conversation, we cover the diagnosis of Long COVID, common symptoms, abnormal test findings, possible mechanisms of disease, the impacts of variants and vaccines, treatments, and the natural history of this condition. We hope this will be helpful for providers, patients, and family members.

Meet Our Guests

Jason Maley is an Assistant Professor of Medicine at Beth Israel Deaconess Medical Center and Harvard Medical School. He is the Director of the BIDMC Critical Illness and COVID-19 Survivorship Program, and the Co-Chair of the American Academy of Physical Medicine and Rehabilitation Postacute Sequeleae of SARS-CoV-2 infection (PASC) initiative. He is NIH funded to study post-COVID patients.

Ann Parker is an Assistant Professor of Medicine at Johns Hopkins and is the Co-Director of the Johns Hopkins Post-Acute COVID-19 team. She is NIH funded with her research focusing on survivors of respiratory failure and critical illness.

Key Learning Points

Long COVID or Post-Acute Sequelae of SARS-CoV-2 or Post-COVID condition

Long COVID was first described this way by patients so this is the common nomenclature that is used. It is also referred to as Post-Acute Sequelae of SARS-CoV-2 or Post-COVID condition
Defined by patients that have not returned to their baseline health 3 months after their acute episode of COVID-19
Major organizations in describing this disease and doing research are:
- World Health Organization
- Multiple patient-led organizations
- CDC – INSPIRE
- NIH – RECOVER

Post-COVID Clinic

Seeing patients across the spectrum of illness. Not all patients had to be critically ill or hospitalized
- The standard patient has changed over time and now the vast majority had a mild initial illness, but afterward had unusual and persistent symptoms
Patients are generally referred by their PCP or self-referred
The criteria for being seen in clinic are very loose to make sure patients are not excluded
- Many patients do not have a confirmed case of COVID since patients early in the pandemic often did not have a positive test available, and now many people are testing positive at home
Initial records review to make sure that can help patients
Standardized questionnaires
- Screening for physical impairment, mental health impairment, and cognitive impairment
Rehabilitation and multi-disciplinary based approach
It is extremely important to be aware of the bias in patient populations in Post-COVID clinics
- The population that can make it to clinic may not, and does not, represent all patients who have had COVID or have Long COVID. Patients may be limited in their ability to get to clinic based on their physical condition, financial resources, location, support, and language barriers.

Overlap of Long COVID and PICS

These conditions are very similar and certainly have a lot of overlap
For patients coming out of the ICU, screening should start with looking for known PICS symptoms.
- These domains are mental health, physical impairment, and cognitive function
There may be some unique aspects, such as:
- Severe persistent fatigue
- Extreme changes in taste and smell

Common symptoms

Many symptoms are complex and multifactorial
Neuropsycholgoicl impairment – termed “brain fog”
- Difficulty with concentration, and cognition
Anxiety
Depression
Persistent shortness of breath
- Dyspnea can be reported even with just talking for long periods of time
- “Deep breaths are just not satisfying”
Cough
Chest pain
Dysautonomia
- Palpitations, dizziness, orthostasis
Fatigue
Post-exertional malaise
Cognitive blunting or “brain fog”
Changes in sleep
Headaches

Common findings on testing in patients with Long COVID

Shortness of breath
- Some may have impaired diffusion (low DLCO) on PFTs
- However, often patients have normal or near-normal PFTs
- 10 – 20 % have air trapping on inspiratory/expiratory chest CTs that could indicate bronchiolitis
- One study showed that CPETs showed impaired oxygen extraction
  - Preserved cardiac output to exercise and no evidence of deconditioning
  - This study indicated an issue at the peripheral level (ex: vascular, mitochondrial) with oxygen extraction.

Variants

It is very difficult to say if variants differ in rates of Long COVID given that often patients do not get sequencing to know the variant and because there is overlap in the timing of variants
Further testing will continue on this going forward

Vaccines

Reduced risk of Long COVID with vaccination
- Boosting further decreases the risk compared to just the initial vaccination
There is a variable response to getting vaccinated if a patient has Long COVID
- Most patients tolerate it well and some patients have relief of symptoms
- There are some patients who can develop worsened Long COVID symptoms

25. ARDS Precision Medicine & Phenotypes Roundtable

Posted on September 20, 2022 by Pulm PEEPs

We’re very excited this week on Pulm PEEPs to be resuming our Roundtable series. We are joined by two outstanding critical care doctors to discuss precision medicine in the ICU, specifically ARDS phenotypes. This is a topic of increasing clinical and research interest, and personalized medicine in the ICU will certainly change the landscape of how care is delivered in the coming years and decades. We are honing in on ARDS today and how phenotyping can influence future research and clinical care.

Meet Our Guests

Carolyn Calfee is a Professor of Medicine and Anesthesia at the University of California, San Francisco. She is a leader in the field of ARDS research and a pioneer in the field of ARDS phenotyping research. She has received numerous NIH grants and has literally 100s of publications on ARDS and other topics. She is also a previous ATS CC Assembly chair, and in 2022 received the ATS Recognition Award for Scientific Accomplishments.

Annette Esper is an Associate Professor of Medicine at Emory University School of Medicine. She works clinically in critical care and is the Medical Director of the stepdown Intensive Care Unit at Grady Memorial Hospital. In addition to her clinical activities, Annette does both clinical and translational research in ARDS, and was the Assembly Chair for the ATS Critical Care Assembly from 2021 – 2022.

Key Learning Points

Berlin Criteria of ARDS:

— Acute symptoms developing within 7 days of a known insult

— Bilateral airspace opacites on chest imaging

— Hypoxemia not fully explained by cardiogenic pulmonary edema

— P:F ratio < 300 on a PEEP of 5

Heterogeneity in ARDS

— ARDS has a broad definition so it is comprised of people with a wide range of disease characteristics and severity

— There is heterogeneity in clinical characteristics, but also underlying biological drivers of disease

— Heterogeneity stymies research efforts to identify effective therapies in ARDS

Phenotyping in ARDS

— There are many ways of phenotyping for critical illness and ARDS

1. Etiology. Examples: COVID vs non-COVID, pulmonary vs non-pulmonary, bacterial vs viral

2. Physiologic phenotypes: Severity (Berlin criteria P:F ratio); Compliance, Ventilatory ratio

3. Biological phenotypes: Different underlying drivers of disease

— The motivation for phenotyping is to find treatment-responsive subgroups within the broader heterogeneous subgroups

— Phenotyping embodies more than risk factors, because it includes information about the host response, not just predictors of outcome

Biomarkers in ARDS

— There is probably a role for biomarkers in ARDS clinically and in research

> Prognostication

> Identify who will be responsive to specific therapies

> May not be one biomarker, will likely be a panel

— What is the perfect ARDS biomarker?

> Specific: identify a group of patients that are at risk, or respond to therapies differently

> Easily measurable at the bedside

> Reliable

> Reproducible

— Challengers in identifying useful biomarkers

> Heterogeneity of disease

> Real world applicability. For example, can you get IL-6 back in real-time? Can you apply it consistently when labs have different testing techniques and scales?

> Temporal stability – how do biomarkers change over the time course of ARDS?

— Biomarkers of interest

> Inflammatory markers (IL-6, IL-8, TNF)

> sRAGE – Soluble receptor for advanced glycation end products

> Highest levels on type 1 alveolar epithelial cells

> Seems to be a marker of alveolar epithelial injuries

> Meta-genomic sequencing of patients in a real-time environment

Latent class analysis

— Clustering technique that, agnostic to outcomes, looks for existing groups within the data

— Ideally, identifies biologically distinct phenotypes that may have different prognoses or response to therapy

Omics in ARDS

— Existing risk scores are quite limited, so using biological data to distinguish patients seems promising.

— Unbiased approach to identifying subgroups to identify patients that behave similarly biologically

— Omics is really thinking about endotyping patients and identifying the biological processes that are driving phenotypes

Hypo and hyperinflammatory phenotypes in ARDS

— Described by LCA incorporating demographics, clinical data, labs, vital signs, 6-8 plasma protein biomarkers

— Importantly, the groups were identified agnostically to outcomes.

— Distinguished by:

> Inflammatory biomarkers (IL-6, IL-8, TNF 1)

> Acidosis

> Shock, vasopressor requirement, and multi-system organ failure

— Consistently across 8 different data sets

— Both RCTs and observational cohorts

— Hyperinflammatory phenotype has dramatically worse clinically outcomes (higher mortality, fewer VFD)

— The different phenotypes respond differently to therapies retrospectively in RCTs

— The phenotypes did respond differently to PEEP, fluids conservative therapy, and simvastatin.

— This was not seen universally (rosuvastatin did not have differential treatment response)

— Note: We don’t really know that inflammation is at the heart of the pathogenesis of what distinguishes these two groups. The “hypoinflammatory” phenotype still has elevated levels of inflammatory biomarkers compared to controls.

What is next?

— This is all just subgroup analysis.

— These hypotheses still need to be tested prospectively

— Need to be able to easily identify the phenotypes quickly and easily

— Working on biomarker-based and non-biomarker-based clinical classifications

Key Quote:

Dr. Calfee “My takeaway point would be, there is no one best or one right way to phenotype these patients. I think there are numerous different approaches that we’re probably going to be using over the years. But I would say that what we want to focus on is what has the potential to change outcomes for our patients and to really identify individual patients or groups of patients that respond differently to therapies. And I think if we can keep that goal in mind and start testing some of these hypotheses prospectively we’re going to make progress.”

Welcome to another episode in our Pulm PEEPs Fellows’ Case Files series! The purpose of this series is to highlight and amplify the incredible clinical work that is done by pulmonary and critical care fellows, share fascinating cases, and assemble a diverse network of pulmonary and critical care educators. Today we’re headed to Baylor College of Medicine to hear about a fascinating case. Tune in, let us know what you think on Twitter, and let us know if you have a great case to share!

Meet Our Guests

Benjamin Moss completed his internal medicine residency training at Baylor College of Medicine in Houston, Texas, and is currently a senior pulmonary and critical care fellow there.

Philip Alapat is an Assistant Professor of Medicine and the Program Director of the Pulmonary and Critical Care Fellowship at Baylor. He completed his residency and fellowship training all at Baylor.

Patient Presentation

A 60s-year-old man with seropositive RA on Rituximab presents with dyspnea and cough, and overall “not feeling well.” For the past week, he has had malaise, body aches, and subjective fever. For the past 3 days, he has had acutely worsening dyspnea that is worse with exertion, but present at rest and a cough with scant sputum production. He had been on Methotrexate previously but within the last year developed pancytopenia and MTX was stopped and he was switched to adalimumab/Humira. His pancytopenias did not resolve, and he was ultimately diagnosed with Felty syndrome (a triad of RA, neutropenia, and splenomegaly) and switched to rituximab every 6 months with his last dose being 4 months ago. During the last week, he tried taking prednisone 10 mg a day but his symptoms did not improve.

X-ray on presentation (L) X-ray 8 months ago (R)

Key Learning Points
