Hepatic encephalopathy in the hospital (An ode to #lactulose):
A brief #livertwitter #tweetorial
Aims:
1. Share the greatest t-shirt ever made
2. Rule out infection!
3. Laxation now! But how?

keywords: #cirrhosis, paracentesis, stool pH
1. This shirt, made by a patient, reminds us:
▶️HE is horrible, unpredictable
▶️Preventing HE is hard
▶️Dont be quick 2 label pts as 'noncompliant' - there's more to the story
▶️Our patients are awesome. Hepatology is the best

#lactuloseorcomatose
2. Think of hepatic encephalopathy as a biomarker.

For what? The answers form a mandatory checklist of sorts

1. Para to r/o SBP. Delay @ your patient's peril. (Fig1)
2. GI Bleeding?
3. UA/Blood Cultures/CXR
3. What's the Cr? Na? K?

3. First line therapy for hospitalized "overt" HE is lactulose

This nonabsorbable disaccharide has been used for HE for >50 years. (Fig1)
It was known even then that there had to be another mode of action beyond frequent BMs
Lactulose's mechanism of action came into focus after a 1966 trial in patients w/chronic HE
Fig1: Design - lactulose before or after sorbitol (osmotic laxative) with run-in
Fig2: HE that occurred on sorbitol could be resolved on lactulose
Fig3: The key difference: STOOL PH!
The same effect occurs after a lactulose enema.

See these data from a randomized trial of tap water vs lactulose enema in @HEP_Journal
ncbi.nlm.nih.gov/pubmed/3301614
How does lactulose lower stool pH?

The answer is that colonic bacteria metabolize the lactulose, spitting out organic acids

Check out this study from @jclinicalinvest comparing the stool output and organic acid concentration after PEG (aka golytely) vs lactulose
And here is the kicker: A little lactulose goes a long way

Even in subjects who had formed stool, lactulose still increased the organic acid concentration!
ncbi.nlm.nih.gov/pubmed/2794043
🥊 PEG vs Lactulose 🥊 The HELP RCT
ncbi.nlm.nih.gov/pubmed/25243839

This remarkable study was led by Dr. Bob Rahimi - who, as a FELLOW, enrolled 50 patients who often present in the middle of the night! #hustle

Lactulose (20-30grams TID) vs PEG Colonoscopy prep (4L)

Who wins?
PEG hastened recovery from HE (Fig1)!

Many patients also preferred the PEG to lactulose (Fig 2)
But...
Before you pop the cork on the Golytely, check out the supplement(Fig1):
84% of PEG patients got lactulose before randomization

CLEARLY you need 2 get the bowels moving (more laxative=better)
but a little lactulose goes a long way. Stool pH not measured.
Also...what's the right dose of lactulose?

When a pt comes in with acute CHF, would we give them their home diuretic dose?

Patients admitted with HE often get ~10-20cc TID
🔥Hot take 🔥 This is not enough: That is a maintenance dose

Your pt needs an induction dose!
Unlike with PEG, you dont need 4 liters, but >20cc lactulose q6-8? Definitely!
I learned how 2 treat HE from nurses when I was an intern. We took what they were doing & standardized treatment for HE. Some extra, frequent doses make a big difference(Fig1)
cghjournal.org/article/S1542-…
In summary:
- Hepatology = the best
- Do that para! Search 4 HE triggers
- Drop that stool pH! Even a little lactulose helps
- Laxation now!! Need frequent BMs on Day 0-1 to treat Overt HE. Take your pick: extra doses of lactulose or lactulose + PEG.

Thanks for stopping by!

Elevated ferritin? Is it hemochromatosis? Probably not!

Join me for a quick-hit #livertwitter #tweetorial?

First in a series on diagnostic testing for liver disease #meded
Patients will tell us their diagnosis - if we are listening
In this @JAMAInternalMed teachable moment a patient with ⬆️AST/ALT & alcohol abuse was tested 4 hemochromatosis.

Ferritin = off the charts
Homozygous for HFE mutations
But did she have hemochromatosis?

See below!

30-day Readmissions!

They can teach us a lot about the management of #cirrhosis
AND
Highlight the systems of care that benefit patients with cirrhosis

Join me for a #livertwitter #tweetorial?

Aims:
1. What
2. Why
3. How to address

#QI #meded
Readmissions are:
1. Common. >1⃣in4⃣ pts readmitted by 30days (Fig1) cghjournal.org/article/S1542-…)
2. Costly. >$700 million/year
3. Morbid. Independently associated w/⬆️risk of death (Fig2)
4. Barely predictable. No matter what variables go in2 the model the AUROC ~0.6-0.7 (Fig3)
Q: Why do patients with #cirrhosis get readmitted so frequently?

What's the deal with pain control in #cirrhosis?
A #meded #tweetorial with QI undertones

Aims:
👍Tylenol
👎NSAIDs (mostly)
🤯Pharmacokinetics in ESLD
🔪Tramadol

If this is a confusing topic for you, you are not alone!
Join me as we try 2 sort a few things out
#livertwitter
Let's start with a real world scenario:

Your patient has cirrhosis with well controlled ascites, HE, and unfortunately comes in with MSK back pain from raucously cheering in vain 4 the Winnipeg Jets.
They ask for advice/treatment. In addition to stretching/PT, you recommend...
Although APAP OD is☠️, @ lower doses it's safest analgesic
Speed limit=2-3g/d (I use 2g)
Wouldnt push it but take solace in:
Fig1: Tylenol tox=NAPQI>Glutathione (👀CYP2E1)
Fig2: Tho ppl assume cirrhosis⬇️glutathione, normal metabolism preserved
Fig3: 1 reason:cirrhosis⬇️CYP2E1

#Tweetorial time! 🚨 Looks like there’s another misconception about #cholesterol and #atherosclerosis making rounds again. This one has to do with the process of #LDL particles entering the arterial wall. So gather round friends and let me science the s*it out of this 🤓 (1/24)
For background, here’s a widely cited series of figures by Nakashima et al. (2007). They performed autopsies on 38 people aged 7-49, who died of non-#cardiovascular causes (2/24)
ncbi.nlm.nih.gov/pubmed/17303781
Nakashima et al. looked for atherosclerotic lesions at different stages, according to a previously published morphological classification scheme. They found them, took slices, stained them to find #lipids and #macrophages and organized them nicely (3/24)

#TWEETORIAL: What does it mean to be a social media 'influencer'? It's more than a popularity contest. Here are 4 ways to slice the data, using #ATS2019 @symplur analytics

1⃣Here's a list of top influencers across all categories by the proprietary Symplur Rank.
Here's the same list, but limited to doctors tweeting #ATS2019 - which is why it's important for your bio to identify you as a professional if you want to be counted within your #hcsm community
Rank is based on multiple factors, including:
1. Relevance to the hashtag - higher scores go to ATS orgs and docs who are active in the ATS community all the time (not just during #ATS2019).
2. Accounts with many followers, but not just any followers...

1/ Ok #medtwitter, here goes my first attempt at a #tweetorial, inspired by a recent question on wards from a learner I didn't know the full answer to:

“How good is a tuberculosis (TB) 'rule-out'?”

To try to answer this question we'll first start with a case.
2/ A 62yo female w/ recent renal transplant and remote hx of pulm TB s/p 1y DOT presents with fever. 4 wks PTA was hospitalized for 2 wks of cough, unintentional 20lbs weight loss & large LUL cavitary lesion on CT.
3/ Extensive work-up including bronchoscopy only reveals +human metapneumovirus. 4 AFB sputum smears and 3 MTB PCRs (including BAL) are negative. AFB cultures are NGTD. Patient is d/c on empiric posaconazole. 1 wk later she returns to ED with temp 102F. Cough is now resolved.

1: What causes WBC/PMN elevation (neutrophilic-predominant pleocytic) ascites? The differential is broad and extends beyond Spontaneous Bacterial Peritonitis (SBP).

(A #MedTwitter and #Tweetorials contribution). Appreciate edits by @ebtapper.
2: 26yoW w/ cirrhosis 2/2 congestive hepatopathy 2/2 hypoplastic L heart syndrome s/p Fontan presented to OSH with fevers, abdominal pain. Prev tx by PCP for ?PID w/ IM CTX, doxycycline. Dx para shows WBC 2480, PMN 74%, total protein 4.3, SAAG >1.1. What is cause of ascites here?
3. Portal Hypertension (PH) due to liver dz causes albumin- and protein-poor ascites. This is due to sinusoidal scarring causing reduced albumin and protein translocation into ascites [Serum-Ascites Albumin Gradient (SAAG) >1.1]. But this case is not due to cirrhosis...

#Tweetorial on #Diagnostics and #Screening interpretation.
An otherwise healthy 40 year old woman comes to you after reading on the internet about a terrible disease that one in a thousand women get, and a highly accurate test that can save her life.
The test is over 99% accurate in people with the disease. For those without disease, the test is only wrong 5% of the time.

You order this test and it comes back positive. The woman anxiously asks you, do I have the disease? What is the chance this woman has the disease?
Assuming they weren't immediately fooled by the "test is only wrong 5 % of the time," most I've asked correctly recognize the stats provided are Sensitivity = 99% and Specificity = 95%, and that the objective is to determine the Positive Predictive Value.
