Electrolytes and urolithiasis

Calcium and magnesium disorders
Prof Lucile Figueres @LucileFigueres

#eraedta21 Image
Calcium and magnesium disorders are the job of every nephrologist.

#eraedta21 ImageImage
Ca and Mg also important post transplant.

#eraedta21 Image
Hypomagnesemia is the most common Mg disorder.

How to diagnose the aetiology of hypomagnesemia?

See the very handy table below.
#eraedta21 ImageImage
Causes of extra renal hypomagnesemia

Always check for the PPI.

#eraedta21 Image
Renal hypomagnesemia is rarer.

A nice table that locates cause according to site along the nephron.

#eraedta21 Image
Very useful summary table of tubulopathies with hypomagnesaemia.

#eraedta21 Image
4 organs are needed to maintain calcium

#eraedta21 ImageImage
Hypercalciuria occurs in 5% of general population and 50% of kidney stone formers.

#eraedta21 Image
How to manage hypercalciuria?

Here’s a handy review for the nephrologist from @ndt @LucileFigueres

#eraedta21 Image
Neprhocalcinosis
- Best test: CT scan.
- Nephrocalcinosis does not mean hypercalciuria.

🧵🚨 Thread alert 🚨 🧵

1/ Let's dive into today's session : “Optimising renal replacement in the elderly” 🫘🧓

With a great panel of experts :
🗣️ @EdwinaBrown_PD
🗣️ @jirotmans
🗣️ @pepinmarion1

Tweets by #ERA24 #SoMe Team @FirketLouisImage
2/ Let’s start with @EdwinaBrown_PD , also president of @ISPD1 , who gave us an amazing talk about how to choose the best RRT option in the elderly patients and especially how (assisted-)PD could be a great option in this population. Image
3/ She first recalled that old age is a conundrum with numerous comorbidities and geriatric syndromes that need to be taken into account in the case of end-stage CKD. Image

Did you miss the latest e-seminar about ADTKD?

Check out the highlights and the following tweetorial to learn how to approach this disease.

Speaker: @ericolinger1
Panel: John Sayer, Jan Halbritter and @ecorneclegall

2/When to suspect a monogenic tubulointerstitial kidney disease?
Ø If family history +
Ø Exclude secondary causes
Ø Do urinalysis, imaging and then genetics Image
3/Mostly a diagnosis of exclusion

Diagnostic criteria from @KDIGO 👇🏻 👇🏻 👇🏻
Ø Family history important but definitive by genetics
Ø Biopsy does not help in diagnosis Image

💥Membranous Nephropathy (MN); New antigens, new disease?
#tweetorialERA #membranous #nephtwitter #FOAMed #tweetorial Image
MN occurs due to immune complex deposition in the subepithelial GBM. @SethiRenalPath reckons classification of MN should be made based on the antigen, much like the nomenclature of complement activated GN following better understanding of the role of complement dysregulation.
☄️Hot off the press review suggesting we should consider MN as a pattern of injury. @SethiRenalPath @CKJsocial

🔍Let's take a look at the discovery of antigens in MN.

⏳for another #tweetorialERA 🥳 @HDiniz_

➡️Native kidney biopsy plays a crucial role in the diagnosis of many conditions and, while generally safe, can be associated with bleeding complications.

Would you biopsy a patient with aspirin exposure?🤔
Bleeding complication rates are low, with less than 2% of patients requiring transfusion and less than 0.5% requiring an intervention to control the bleeding.

⚠️These complication rates are higher in hospitalized patients and those with AKI.

cjasn.asnjournals.org/content/15/11/…
But not every patient has the same risk of bleeding 🩸

Risk factors include anemia, thrombocytopenia, frailty index, obesity, comorbidities, and kidney function.

Time for a tweetorial on renal MRI! MRI is used to look at structure, but advanced sequences can measure function too. Multiple sequences in 1 session = multiparametric MRI = loads of data!

Could be used to triage risk in CKD, reduce invasive tests, or for translational research
An imaging biomarker is already being used in clinical practice. For which condition?
It's ADPKD! 🙌🙌🙌

Total kidney volume is approved by the FDA to identify patients at high risk of progressive renal impairment to treat with tolvaptan. TKV is best measured by kidney MRI and evaluated using the Mayo classification Image

💎Electrolytes and Acid-base for the future @HDiniz_ #eraedta20

2⃣ Urinary electrolytes in the clinic: a still unexploited instrument by @GianniCapasso4 Image
⚠️Urinary electrolytes are useful! #eraedta20

➡️ AKI and CKD
➡️ Tubulopathies
➡️ Nephrolithiasis
➡️ OncoNephrology Image
↪️AKI and CKD #eraedta20

⚠️Urinary 'lytes can be used not only for AKI urinary indices but can also can be a marker of CKD progression! Image
