High Impact Clinical Trials
TESTING Study: Steroids vs. Placebo in High Risk IgAN @VladoPerkovic
💥Conclusion: A 6-9 month course of oral methylprednisolone reduced risk of major kidney outcomes by 47% and kidney failure by 41% #KidneyWk
TESTING Study - Basline Characteristics
Effect on primary outcome based on full and reduced Steroid dose
Take home message: Low dose Steroid is the comeback kid for IgAN Rx but need to be accompanied by PCP prophylaxis.
Most infections seen with steroids use occurred in the first 12-weeks
Steroid dose in TESTING IgA Trial

-Nephrology is consulted for Urine output of 9L in one day
-Pt. with AML, T2DM has been in the hospital for > 2 weeks for pneumonia, sepsis & subsequently developed Sweet Syndrome & was started on steroids
1/
Approach to polyuria
Step: 1
Is this water diuresis or solute diuresis?
-Check urine osmolality
Measured Urine osm. = 368 mOsm/kg
So, total daily osmole excretion = 3312 osmoles (368 X 9 L as the patient’s urine output is 9L)
This is solute diuresis
2/
Why is this solute diuresis?
Normal daily osmole excretion in an adult on a regular diet is about 750-900 mOsm/day
This patient’s urine osmolar excretion in one day was
3312 osmoles

Dr. Fuller Albright, in 1941, was the first to postulate the presence of a ‘substance’ that caused features of hyperparathyroidism in a cancer patient

In this report, Dr. Albright essentially described the presence of PTH-like hormone in a cancer patient.
“I suspected that the tumor might be producing PTH. I therefore had it assayed but no PTH hormone was found”-Albright👇🏽 3/ nejm.org/doi/full/10.10…
⚡️Antibody (Ab) response to Pfizer vaccine in hemodialysis pts. has been reported, but the Ab response to Moderna vaccine in hemodialysis patients is not well known
Here we report Ab response to Moderna vaccine in patients on maintenance hemodialysis
2/
⚡️61 hemodialysis patients received the 2-dose Moderna vaccine series
-Of the 61 hemodialysis patients, 20 patients had prior h/o COVID-19

⚡️It important for Nephrologists to be familiar with immune checkpoint inhibitor induced endocrinopathies as thyroid, pituitary & adrenal disorders can present with👇🏽
-Hyponatremia
-Hyperkalemia
-Metabolic acidosis
-Hypotension

⚡️Immune checkpoint inhibitors (ICIs) are monoclonal antibodies that target immune checkpoint proteins:
