Tweetorial: @goKDIGO Level 2B Recommendation - We suggest that adults w/ high BP & CKD be treated with a target SBP <120, when tolerated, using standardized office BP measurement (1/9) #Nephpearls
π kdigo.org/guidelines/bloβ¦
There is evidence that targeting SBP <120 when measured under standardized conditions, reduces CV events & all-cause mortality in CKD
π In most people w/ high BP (incl. frail & elderly), these benefits appear to outweigh the risks of harm (hypotension & AKI) (2/9) #Nephpearls
If the patient cannot tolerate SBP <120 despite a slow, gradual decrease in SBP over months, efforts should be made to maintain SBP <130, <140, or an even higher tolerated SBP goal (4/9) #Nephpearls
Individualization based on trial and error prevails, as in many aspects of medical practice (5/9) #Nephpearls
The importance of standardized BP measurement when applying this guideline cannot be overemphasized (6/9) #Nephpearls
π Routine, non-standardized office BP measurements often, but not invariably, overestimate BP compared to measurements under standardized conditions
No correction factor can be used to convert routine BP to standardized BP measurement by calculation (7/9) #Nephpearls
Wide pulse pressure (common in CKD) implies that achieving SBP <120 will almost certainly result in DBP <70 in the majority making a separate DBP target redundant
Literature on RCTs targeting DBP w/ clinical outcomes is scarce (esp. in CKD)
One should not rely on routine office BP to adjust BP-lowering therapy (9/9) #Nephpearls
π It should be noted that @HTNCanada recommends an SBP target <120 using standardized BP measurement consistent w/ @goKDIGO guideline
In ADPKD, as compared w/ standard BP control, rigorous BP control was asso. w/ slower increase in total kidney volume (TKV), no overall change in eGFR, a greater decline in LV mass index, and greater reduction in urinary albumin excretion #Nephpearls
IgA Nephropathy: The @goKDIGO treatment algorithm recommends consideration of use of corticosteroids in patients with "persistent proteinuria >1g/day" if the risk/benefit profile is favorable
π A GFR of 30 is considered a threshold for treatment
Nephrolithiasis 101: When to order a 24-hour urine collection #Nephpearls
Multiple or metabolically active stones (stones that increase in size/ number w/in a year)
Children
Demographic groups not typically prone to stone formation
Stones other than those containing calcium
