CKD Flashcards
KDIGO AKI criteria
↑ creat 0.3+ within 48 hoursOR↑ creat greater than 1.5x baseline within last 7 daysORurine vol less than 0.5 mL/kg/h FOR 6 HOURS
nephrotic v nephritic
Otic = damage to podocytes = holesItic = inflammation = bloody time
focal segmental glomerulosclerosis
1 seen clinicallyhypertension (always)nephrotic syndromeasymptomatic or microscopic proteinuriarenal insufficiency↑ risk progress to ESRD
FSGS dx
RENAL BIOPSY
FSGS tx
corticosteroids + immunosuppressant
IgA nephropathy
2 seen clinicallyaka Berger’s - IgA settles in kidneys = glomerulonephritisoften only manifestation is hematuriagood BP w/o large proteinuria often doesn’t progress to ESRD
IgA nephropathy tx
BP control w ACE-I or ARBproteinurialt 1g - typically no txgt 1g - 6 mo steroid trial, maybe immunosuppressants
IgA s/s
often only manifestation is hematuria
IgA nephropathy and proteinuria relationship
lt 1g - typically no txgt 1g - 6 mo steroid trial, maybe immunosuppressants
primary glomerular disease x2
FSGSIgA nephropathyAcute GN, MCD, FSGS, MN, MPGN, IgA Nephropathy, Post Infectious GN, Anti‐GBM Nephritis
secondary glomerular disease example
SLESLE, Wegner’s Granulomatosis, Vasculitis, Goodpasture’s Syndrome, Hepatitis C, Hepatitis B, HIV
SLE + kidney relationship
nephropathy! secondary glomerular diseasemore females, and younger
SLE glomerular disease s/s
often present, not always: proteinurianephrotic syndromehematuria
SLE glomerular disease dx
renal biopsycomplement (see depression), anti-dsDNA, anti-nuclear ab (positive)
IgA nephropathy dx
RENAL BIOPSY
** renal biopsy as dx **
FSGSIgA nephropathySLEnephritic syndrome
nephrotic vs nephritic setting
OTIC: chronicITIC: acute (biopsy to dx/tx STAT)
nephrotic vs nephritic mechanism
OTIC: podocyte injury, changed architecture (scar, matrix deposition)ITIC: inflammation, GBM break, crescent formation
nephrotic vs nephritic onset
OTIC: insidiousITIC: abrupt
nephrotic vs nephritic edema
OTIC: largeITIC: small - mod
nephrotic vs nephritic BP
OTIC: normal - lowITIC: HIGH
nephrotic vs nephritic proteinuria
OTIC: LARGEITIC: small - mod
nephrotic vs nephritic hematuria
OTIC: eh maybe, maybe notITIC: MOD - LARGE
nephrotic vs nephritic RBC casts
OTIC: absentITIC: present
leading cause of CKD in US
DIABETIC KIDNEY DISEASE! (diabetic nephropathy)
** diabetic kidney disease dx **
CLINICAL PRESENTATION! often r/t poorly controlled DMACR- macro OR - micro + diab retinopathy or T1DM x10 years
** ACR is… **
albumin:creatinine ratiomacro: greater than 300 mg/gmicro: 30 - 300 mg/g
