1/16 Inspired by #NephMadness, let’s briefly touch on:

💢Role of kidney biomarkers in patients with CHF
💢‘Worsening kidney function’ in heart failure
💢Permissive hypercreatininemia
💢Handling RAASi and SGLT2i in heart failure

2/16 Let’s have a poll.
Forward failure, characterized by decreased kidney perfusion, is the main determinant of kidney dysfunction in acute decompensated heart failure. Is this true or false?
3/16 That’s false!
◀️“Backward failure” (Kidney congestion, interstitial edema and tubular dysfunction) is believed to play a more vital role compared to “Forward failure”▶️ (decreased kidney perfusion)
Neurohumoral and inflammatory mechanisms also operate

2/ 🧵 Where does the word malaria originate from?

PMID: 11053494
3/🧵 Malaria is an Italian word composed of “mala” and “aria,” meaning bad (malus) air (aeris). It was first used to describe a fever (miasma) mistakenly attributed to exposure to poisonous air.

🎤“Don’t make a change too complicated, just begin.”

🔊 We have a chance to make a ‘change for good’ in anemia Rx in CKD.

👥Let’s discuss hypoxia-inducible factor prolyl hydroxylase inhibitors (HIF-PHIs), the probable champions🏆 of NephMadness 2021. #AnemiaRegion
2/ 📖Hypoxia Inducible Factor (HIF) - Physiology

- Present in all tissues.
- Has O2 regulated 𝞪 (3 isoforms) and constitutively expressed 𝛃 subunits.
- HIF-2𝞪 is expressed in the peritubular fibroblasts, mainly involved in the upregulation of EPO gene.
3/

🗝️↓ Hypoxia, HIF 𝞪 heterodimerizes with 𝛃 subunit in the nucleus → the complex binds with DNA sequences called hypoxia response elements → Gene activation → ↑ RBC production by ↑ essential protein synthesis linked with iron and EPO pathways. mdpi.com/1422-0067/19/2…

1/ When bubbles settle on the surface of the urine it indicates disease of the kidneys-Hippocrates

In the day, urinary exam was so crucial, the urine flask was as much a symbol of a physician as today's white🥼!

🧵Is proteinuria a worthy rival to GFR?
#Nephmadness #primarycare
2/
*⃣Normal urinary protein excretion is <150mg/d and comprises mainly Tamm-Horsfall proteins, with very little albumin (5-10mg/d)

*⃣ We don't understand what happens to albumin in the kidney 💯

*⃣ But overall the degree of albuminuria is a ⚖️of filtration + reabsorption 👇
3/Albuminuria is common in injury to the GBM (GLOMERULAR proteinuria)

But non-albumin proteins sometimes dominate the filtrate.
The classic case is OVERFLOW proteinuria in paraproteinemia

1/ I often get asked about the presence of granular casts on the automated UA reported by the lab whether it is equivalent to seeing muddy brown casts.

❓Do you think granular casts can be used to diagnose ATN?

More to see in #NephMadness on #liquidbiopsy
@NSMCInternship
2/ Spin the urine! This is one of the maneuvers that I enjoy doing with residents the most as there is a lot to uncover.

I totally underestimated the power of this test. How many times have you spun the urine yourself before nephrology training?
3/ The clinical properties of urine have long been described by the medical community.

‘Diabetic’ (polyuric) disorders were classified as ‘mellitus’ (honey-sweet) or ‘insipidus (flavorless) based on the urine’s taste!

1/ Monitoring eGFR in CKD is almost a reflex🦵!

But how did we get here?
What are we trying to assess?
And how does eGFR help?

#NephMadness #primarycare pits GFR vs proteinuria in CKD

In this tweetorial let's take a closer look at GFR

But first, who has your vote?#NephTwitter
2/ The concept of GFR as a marker of kidney function dates way back to the 1950s. (Apologies to the tubules, we do❤️you!)

But how could we measure GFR??

It was suggested that if a solute had certain characteristics its plasma clearance would = GFR

Let's briefly recap🤓
3/ The solution, INULIN, a non-toxic exogenous molecule, came through studies on aglomerular fish! #AnimalHouse

INULIN renal clearance= measured GFR
It is considered the GOLD standard🏆

But it comes with baggage
🧳It's expensive
🧳It's tedious
🧳It's hardly available anymore

It has been more than a century tackling Anemia in CKD since its first description by Richard Bright in 1835.

👉 #NephMadness 2021 is featuring strong contenders from the #AnemiaRegion.

🤔 Let's find out why Anemia in CKD is an important consideration. #NSMCInternship
2/📊 What % of patients with CKD stage 4 have anemia based on KDOQI (Hb <13.5 g/dL for men and <12.0 g/dL for women) and WHO (<13.0 g/dL for men & <12.0 g/dL for women)?
3/

😳 Around 60% of the patients with stage 4 CKD not on dialysis have anemia based on KDOQI/WHO.

😟 Anemia contributes to significant morbidity in patients with CKD.

You see a patient w/ a past history of C-section for poor inflow/outflow 1️⃣ week post laparoscopic PD catheter insertion
📊What are the possible causes of flow problems?
2/

What’s your approach to flow?

1️⃣ Catheter irrigation → 1L of solution (dialysate/saline)
2️⃣ If slow fill → Flush/aspirate with syringe (aseptic technique! 🧤 😷)
3️⃣ If resistance both ways → Likely two-way obstruction

👇 Use an approach to catheter flow problems:
3/

➡️⬅️obstructions due to intraluminal/extraluminal process

👉Fibrin → most common cause of intraluminal obstruction

👉Fibrin → arises with inflammation (e.g. peritonitis)/embedded catheters too!

👉 Diagnose by clinical suspicion (🔎 for fibrin traces in drain bag)

1/ What causes #AKI with extracorporeal membrane oxygenation (ECMO)?

🗣️🗣️Let’s explore this 🔥topic from #NephMadness 2021

🧵#tweetorial #CriticalCare #NephTwitter @NSMCinternship @ASPNeph

Poll: How common is AKI in patients receiving ECMO?
2/ Basics first:
⚡️ECMO: temporary mechanical assistance device that provides prolonged cardiopulmonary support

⚡️Venovenous (VV) ECMO→ full respiratory support
⚡️Venoarterial (VA) ECMO→ both respiratory and hemodynamic support

⚡ Protocol Biopsies in Lupus Nephritis (LN)⚡
1/ Let's take another stab at (pun intended?) protocol biopsies in LN!

💡 The idea is certainly not new - it has been successfully implemented in kidney transplant recipients #NephTwitter #Tweetorial #FOAMed @NSMCInternship
2/ Out of curiosity - have you asked for repeat biopsies in these patients? When & why? Does your hospital have a protocol for it? Share your experience in the comments too! 👇
3/ I mean, you nailed the diagnosis the first time around, right? So why would you ask for a repeat kidney biopsy in a patient with LN? 🤔

What makes the kidneys more susceptible to acute injury from climate change?
Kidney is an amazing organ🙃🙂

⚡️It excretes concentrated waste ( To minimize fluid loss)
⚡️It is highly metabolic work🥵🥶

SGLT2i Pearls:

1. SGLT2 inhibitors have significant long-term protection of GFR. However, because they cause afferent arteriolar vasoconstriction, expect to see an acute drop in GFR after initiating.
2. SGLT2 inhibitors work w/ ACEi/ARBs & can still provide improvement in renal outcomes for pts w/ diabetic kidney disease on max dose ACEi/ARB.

3. Patients already on thiazide can experience significant volume loss with SGLT2i initiation. Consider reducing or stopping thiazides

Speaking of staying at home 🏠... let’s not forget that #AdvancingAmericanKidneyHealth (AAKH) aims to have 80% of people with kidney failure use a home dialysis modality or obtain a transplant by 2025. Do you know how close we are to that goal?
#NephMadness #EthicsRegion
2/
As of December 2017, the USRDS reported 38% of people with kidney failure (or end stage renal disease/ESRD) in the United States were either on peritoneal dialysis (PD), home hemodialysis (HD), or had a functioning kidney transplant. What’s the breakdown of each modality?
3/
By and large, that 38% is made up of transplant - 30% of all ESRD patients have a functioning kidney transplant. Only 7% are on PD, and 1.3% are on home HD. The rest of our patients (~ 61%) receive in-center HD.

Ever wondered
What do they do to electrolytes❓
Why r these diuretics not associated with electrolyte depletion❓

Let's dive deeper🔓
#medtwitter #NephMadness #SGLT2iRegion
What is the impact of SGLT2i on Na and water hemostasis?
First, let’s revisit, how Na and glucose are handled in the nephron 📜
💥100% of the filtered glucose is reabsorbed along the nephron (90%, via SGLT2 in PCT)
💥1 Na+ ion for every glucose molecule gets absorbed from the lumen
💥In PCT 60 - 80% of sodium is reabsorbed

I’ve been working on my #medtwitter elevator pitch. Mostly because lately I seem to have lots of fleeting conversations about it.

And I know I’m not alone.

Here's what I find:

Some are sold but nervous.
Some are intrigued but don’t get it.

And a lot are precontemplative.
2/
I think it’s because it can seem like all #medtwitter users look the same.

Them: “I would get on Twitter but I’m not a social media person.”
Me: “Twitter is different! Even if you don’t do social media!”
Them: 😐“Nah. Can’t see it.”

*ping*

Them: ✌️🏾

Elevator ride over.
3/
But I’ve been thinking about the many different #medtwitter identities there are. Most can find a fit nestled somewhere in 1 or a few of them.

What works for each person depends on a few things:

Who you are
What you hope to get from it
What’s going on in your life

Yup.
