Key Learning Points

Steroids do not treat the infection — antimicrobials are always first and remain the cornerstone. The goal is addressing critical illness–related corticosteroid insufficiency (CIRCI), where cortisol production cannot keep up with the overwhelming inflammatory demand of septic shock.

Hydrocortisone helps in two main ways:

Clinical takeaway: The first thing you notice is vasopressor weaning (or a bend in the escalation curve) — not a rapid improvement in fever or white count.

Caveat: These trials predate modern sepsis phenotyping. None distinguish hyperinflammatory vs. hypoinflammatory responders — they treat all comers.

Every IM resident and critical care fellow will eventually journal-club these four. The most consistent signal across all of them is faster shock reversal and reduced vasopressor use; the mortality question remains unsettled.

Bottom line: Faster shock reversal is consistent. Mortality benefit appears in 2 of 4 trials (both used fludrocortisone) but not the others. A 2026 meta-analysis showed benefit for hydrocortisone + fludrocortisone vs. placebo, but

not for hydrocortisone + fludrocortisone vs. hydrocortisone alone — suggesting hydrocortisone drives the main effect.

A practical escalation sequence: escalating norepinephrine → add vasopressin (per VASST) → then add steroids if requirements keep climbing.

Do NOT wait for an ACTH stimulation test. It does not reliably predict who responds and only delays treatment. Sepsis is an elevated-cortisol state but can dissociate ACTH and cortisol, and cortisol-binding globulin is depleted — the test is too messy to guide care.

Two things we know: (1) steroids shorten duration of vasopressor support, and (2) they are relatively safe in sepsis. Whether they improve mortality — and in whom — remains open.

Episode Transcript

Hey everyone, Dave Furfaro here from Pulm PEEPs. As you may have noticed in the last few weeks and months, we’ve had a little bit of a decrease in the content that we’ve been putting out, and I just wanted to share a couple things with you about why that is and the future of Pulm PEEPs coming up. In December of 2025, I was diagnosed with a large myxoid liposarcoma in my leg, and since then, I have been undergoing treatment for that.

Overall, treatment has been going well, but it’s certainly been a long road that, continues, and I hope that it continues to trend positively. Kristina has been an unbelievable support during this. We have continued to work on some content as a great way and distraction for me at times, but we haven’t been able to keep up the same pace of content that we usually put out. And given everything that is going on, I actually anticipate that will continue for a few months. Ee haven’t said anything so far yet because we were still figuring it out ourselves, but now we just wanted you all to know that, we, love doing Pulm PEEPs. We’re very committed to it. We wanna get back to doing it as consistently as we have been previously, and we plan on doing that, but it likely will be a little bit of time, and this is why.

I also may be sharing more about my journey through the medical system as a patient, in the future, but for now, I’m really just focusing on my treatment, my health, and my family. So the summer months will likely be, much slower, maybe even a break off together, and look forward to recovering and getting back to producing more regular Pulm PEEPs content in the Fall.

Hope everybody who’s listening is doing well. Thank you all, as always, for being supportive, for listening to the podcast, for reaching out to us on social media, for saying hi to us in person at conferences. It’s been, a true delight, and we can’t wait to get back to business as usual. Okay, everybody. Take good care of patients, be safe, be well, and we’ll see you soon.

We’re excited today to launch our first episode in collaboration with the Irish Thoracic Society and their podcast series. The Irish Thoracic Society represents respiratory professionals throughout Ireland and is dedicated to championing excellence in the prevention, diagnosis, and clinical care of respiratory disease through its work in advocacy, education and research.

In today’s episode, we explore the complex and often overlooked world of refractory chronic cough — a condition that can significantly impact patients’ quality of life but is frequently misunderstood or underdiagnosed. With insights from leading respiratory specialists in Ireland and the United States, we discuss the latest thinking on diagnosis, management, and emerging treatments aimed at improving outcomes for patients and helping clinicians navigate this challenging area of respiratory medicine.

Joining us are renowned experts Professor Lorcan McGarvey and Professor Brendan Canning, both internationally recognised leaders in respiratory medicine and cough research. Together, they share their perspectives on the neurobiology of chronic cough, the considerable morbidity experienced by patients, and how clinicians can approach diagnostic investigations more effectively.

We also explore current treatment strategies and promising new therapies on the horizon as chronic cough increasingly gains recognition as a disease in its own right — rather than simply a symptom. Whether you’re a clinician, researcher, or simply interested in advances in respiratory medicine, this episode offers valuable insights into a condition that is finally receiving the attention it deserves.

Key Learning Points

Why these guidelines matter:

This is the first joint AHA/ACC clinical practice guideline specifically on acute PE, bringing together a truly multidisciplinary writing committee (cardiology, pulmonology, hematology, emergency medicine, interventional radiology, surgery, and others). Prior guidelines existed from individual societies, but nothing this comprehensive had been updated in roughly five to six years.

New PE clinical categories (A through E):

One of the most impactful changes is replacing the old “massive/submassive” and “low/intermediate/high risk” labels with five categories that form a severity continuum. Category A is subclinical (incidental PE found on imaging in asymptomatic patients). Category B covers symptomatic but low-severity patients. Category C is where much of the clinical complexity lives — symptomatic, hemodynamically stable patients subdivided into C1, C2, and C3 based on RV function and biomarkers. Category D represents incipient cardiopulmonary failure (transient hypotension, normotensive shock with end-organ dysfunction). Category E is frank cardiopulmonary failure, with E2 being the sickest — refractory or recurrent cardiac arrest. Respiratory modifiers (hypoxia requiring supplemental oxygen) layer onto C, D, and E.

Diagnostic approach:

Clinical evaluation comes first — history, exam, and validated decision tools (Wells score, revised Geneva, PERC). If clinical probability is low and D-dimer is normal, imaging can be safely avoided. If either is concerning, imaging is warranted. CTPA remains the preferred imaging modality due to superior sensitivity, specificity, wide availability, and ability to assess clot burden and alternative diagnoses. VQ scanning is still appropriate when CTPA is contraindicated, and VQ SPECT offers better reproducibility and specificity than traditional planar VQ if available. Echocardiography is not a diagnostic test for PE but is important for risk stratification — RV size, TAPSE, and tissue Doppler measures all contribute prognostic information.

Anticoagulation updates:

Anticoagulation remains the cornerstone of treatment. For patients potentially needing advanced therapies (C3, D, E), parenteral anticoagulation is started first. A notable recommendation: low molecular weight heparin is generally preferred over unfractionated heparin, based on evidence showing more effective VTE risk reduction, more predictable pharmacokinetics, no need for routine monitoring, lower rates of heparin-induced thrombocytopenia, and no increase in major bleeding. The committee acknowledged this may create discomfort for clinicians accustomed to unfractionated heparin’s easy reversibility, but the difficulty of achieving and maintaining therapeutic levels with UFH was a significant concern.

Advanced therapies:

Catheter-based thrombolysis, mechanical thrombectomy, systemic thrombolysis, and surgical embolectomy all received mostly class 2B recommendations (“can consider”) for C3 and D categories, reflecting that current evidence shows improvement in short-term surrogate measures (RV/LV ratio, hemodynamics) but lacks definitive hard outcome data on mortality. For category E1 patients, recommendations are stronger (class 2A). Multiple trials are expected soon — HI-PEITHO, PEERLESS-2, PE-TRACT, PERSEVERE, TORPEDO, and PROG — that should substantially inform future updates.

PERT teams:

Pulmonary embolism response teams are encouraged, particularly for C3, D, and E patients. They’ve been shown to reduce length of stay. For institutions without PERT capability, establishing consultation networks with larger centers is recommended.

Post-PE follow-up:

Patients shouldn’t be “left in the wilderness” after discharge. The guidelines recommend communication within the first week to ensure understanding of diagnosis and treatment, an in-person visit at or before three months to assess for persistent symptoms and discuss anticoagulation duration, ongoing surveillance for chronic thromboembolic pulmonary disease, and periodic reassessment for those on extended anticoagulation.

Key Learning Points

What the Test Measures

Test Performance

Where It Fits in the Asthma Workup

The test belongs in a stepwise approach:

It is most useful for symptomatic patients with normal spirometry and no bronchodilator reversibility. Given its cost, mild risk, and discomfort, it should not be a first-line test — most asthma diagnoses do not require it.

Technique and Medication Prep

Technique

Medication Washout (to Avoid False Negatives)

Interpreting Results

On this week’s episode, we’re continuing our Guidelines Series exploring the 2022 ESC/ERS Guidelines for the diagnosis and treatment of Pulmonary Hypertension. If you missed our first episode in the series, give it a listen to hear about the most recent recommendations regarding Pulmonary Hypertension definitions, screening, and diagnostics. Today, we’re talking about the next steps after diagnosis. Specifically, we’ll be discussing risk stratification, establishing treatment goals, and metrics for re-evaluation. We’ll additionally introduce the mainstays of pharmacologic therapy for Pulmonary Hypertension.

Key Learning Points

1) Episode Roadmap

2) Case-based diagnostic reasoning

Patient: 37-year-old woman with exertional dyspnea, mild edema, abnormal echo, telangiectasias + epistaxis → raises suspicion for HHT (hereditary hemorrhagic telangiectasia) and/or early connective tissue disease.

HHT teaching point: HHT can cause PH in more than one way:

3) Functional class assessment

WHO Functional Class:

Practical bedside tip they give:

4) Risk stratification at diagnosis: why, how, and which tools

Big principle: treatment choices are driven by risk, and the goal is to move patients to low-risk quickly.

ESC/ERS approach at diagnosis (as described):

ESC/ERS risk assessment variables (10 domains discussed):

They note: even if you don’t have everything, the calculator can still be useful with ≥3 variables.

REVEAL 2.0:

Case result: both tools put her in intermediate risk (ESC/ERS ~1.6; REVEAL 2.0 score 8), underscoring that mild symptoms can still equal meaningful mortality risk.

5) Treatment goals and follow-up philosophy

What they explicitly prioritize:

Also emphasized:

6) Medication classes for the treatment of PAH

Nitric oxide–cGMP pathway

Endothelin receptor antagonists (ERAs)

Prostacyclin pathway

7) Sotatercept (post-guidelines)

They note sotatercept wasn’t in 2022 ESC/ERS but is now “a game changer” in practice:

8) How risk category maps to initial treatment intensity

General approach they outline:

For the case: intermediate-risk → start dual oral therapy (they mention tadalafil + ambrisentan as a typical choice), reassess in ~3 months; add a third agent (e.g., selexipag/prostacyclin pathway) if not low risk.

Practical takeaways for real-world use

This week’s Pulm PEEPs Pearls episode is a focused discussion between Furf and Monty about non-pharmacologic techniques for airway clearance in the non-Cystic Fibrosis bronchiectasis population. This is a focused, high-yield discussion of the key points about airway clearance, including practical tips and a discussion of the evidence.

This episode was prepared in conjunction with George Doumat MD. Goerge is an internal medicine resident at UT Southwestern and joined us for a Pulm PEEPs – BMJ Thorax journal club episode. He is now acting as a Pulm PEEPs Editor for the Pulm PEEPs Pearls series.

Key Learning Points

1) Why airway clearance matters in non-CF bronchiectasis

2) What ACTs are trying to achieve clinically

3) The main ACT “families” and when to use them

Breathing-based techniques (device-free, flexible)

PEP / Oscillatory PEP (stents airways + “vibrates” mucus loose)

Mechanical/manual techniques (help when patient can’t self-clear well)

4) How to choose the “right” technique (the practical framework)

There is no one-size-fits-all. Match the tool to the patient:

A key mindset from the script: this is not a lifetime contract—reassess and adjust over time with shared decision-making.

5) Evidence takeaways (what improves, what doesn’t)

6) Special population pearls

7) The “real” bottom line
