Let's start with a problem representation:
A 74 yo M with a PMH of myelofibrosis not currently under therapy and recently treated for CAP presents from his pulm clinic w/ SOB, recurrent fevers, and GERD like sxms found to have a recurrent infiltrate on Xray.

The first question is this another "CAP"
Is the patient on a JAK inhibitor? is patient pancytopenic?
That really impacts the ddx
We all wish we knew about Myleofibrosis..

Myelo- comes from ancient Greek,in which the same word μυελός (myelos) was used to describe three things: bone marrow, the spinal cord, and, to a lesser extent, the brain.
Why the same word for these unconnected organs/tissues, Dr. Hippocrates?

I would assume immunocompromised host until prove otherwise
is this primary or secondary myelofibrosis as PV could lead to MF.
with MF I imagine cytopenias and a big spleen (sometimes a big liver)

Anyone familiar with Wacker’s triad? A Triad for the Diagnosis of Pulmonary Embolism and Infarction from 1961.

Has anyone seen Dr. Redelmeier’s essay about why we should no longer teach triads? onlinelibrary.wiley.com/doi/abs/10.111…
Back to this "infiltrate" is the infiltrate in the lung infectious/inflammatory noninfectious or something else (cells?)
A good 2 view (PA & LAT) can really help

Cool genetics of MPN: JAK2 > CALR & MPL, although plenty of other genes can be mutated, and a subset are “triple-negative”
ALR is an ER chaperone protein, & MPL is the TPO receptor,which makes total sense for a MPN!
typical tx for primary MF=ruxolitinib, ncbi.nlm.nih.gov/pmc/articles/P…

it's never a "CAP" until treated as CAP

Rigors are actually a good predictor of bacterial infection

@haematognomist MPN pearls, in this case for Polycythemia Vera. The CYTO-PV trial showed that “among patients with JAK2-positive polycythemia vera (PV), maintaining a target hct of <45% has a🔽rate of fatal & non-fatal cardiovascular or thrombotic events vs hct of 45-50%.”
Since pt was on ruxolitinib it created some chat
The most frequent infections on jak inhibitors per case reports, were tb (N = 10), hep B reactivation (N = 5) & PJP infection (N = 2). pubmed.ncbi.nlm.nih.gov/29150886/
baricitinib is a new jak inh tested in COVID, contagionlive.com/news/arguing-t…

His work history opens theories of fungal infections in NC. Histo? Blasto?
CD doesn’t list any reportable fungal diseases for NC, cdc.gov/fungal/fungal-…

"antibiotic refractory pulmonary syndrome" a new fun term
Could this be TB? linezolid, quinolones and macrolides treat TB and could have been given for CAP.
Ruxolitinib discontinuation can cause ARDS — researchgate.net/publication/26…

For someone with an established condition, now w/ new illness:
1. Is it a flare of that disease (ds)?
2. Is it a complication of that ds?
3. Is it a complication of the tx for that ds?
4. Is it something entirely new?
And infiltrates could be non-expectorated alveolar blood

Intermittent hemoptysis without progressive lung disease also makes me think of HF & lung AVMs
Inhibition of JAK-STAT signaling pathway by Ruxolitinib results in a dramatic🔽in levels of inflammatory cytokines, such as IL-6 & TNF-α.
maybe increased risk of TB w/ tnf being low?

Faget’s sign -have learned to reflexively look at at med list
Big spleen, lung infiltrate, fingernail bruise. hmm..
is it a splinter hemorrhage?
disseminated fungi like Fusarium, blasto, candida can be at play here
i still think we need a ct and bal/biopsy

Most common rhythm in pe is ST, 10%–25% of patients with PE have a normal ECG.
A true left shift is when there are bands
Biatriospora mackinnonii infection, a form of phaeohyphomycosis. Think brown-pigmented (dematiaceous) molds, which can often get inoculated thru trauma

Recurrent pneumonia different from non-resolving pneumonia….recurrent pneumonias resolve then come back….most common cause of recurrent pneumonia is aspiration
Final dx: Recurrent aspiration w/ pneumonitis related bleeding
