Nephrology Flashcards
Fever, rash, eosinophilia, renal impairment, HTN
White cell casts
Acute interstitial nephritis
Vitamin def - CKD vs AKI
CKD = hypocal (reduced Vit D)
Drugs to stop in AKI
As may worsen AKI; NSAIDs, Aminoglycosides, ACEi, ARBs, Diuretics
Due to risk of Tox; Metformin, Lithium, Digoxin
Pre-renal Uraemia vs ATN
Pre-Renal - Kidneys hold on to sodium - Urine Na <20 good response to fluid challenge
ATN - Urine Na >40
AKI staging
1 - inc Cr 1.5-1.9 or > 26.5. UO < 0.5ml/kg/hr for > 6hr
2 - 2-2.9, UO < 0.5 12 hr
3 - > 3, Cr > 350, UO < 0.3ml/kg for > 24hr
ADPKD ft and asso
Ft; HTN, recurrent UTI, flank pain, haematuria, palpable kidneys
Extra-renal manif; liver cysts, berry aneurisms
Child; microscopic haematuria, progressive renal F, bilat deafness
Alport syndrome - Abnormal GBM
typical Q - failing renal transplant - presence of anti-GMB abs
Raised Anion Gap metab aci
= gap > 14
Lactic aci, excess ketones, renal failure (raised urate)
Normal anion gan metab aci (8-14)
GI bicarb loss (diarrhoea)
RTN
Addisons
Dietary advice CKD
Low prot/Phos/Na/Ke
GFR and CKD staging
1 - eGFR > 90 but signs of damage
2- 60-90 but signs
3a - 45-59
3b - 30-44
4 - 15-29
5 - <15
Child - AKI, MAHA, Thrombocytopenia
HUS - Shiga EColi (O157:H7)
Supportive Tx
Child, recent infection - palpable purpuric rash/oedema over buttocs and extensor surfaces, abdo pain, polyarthritis, haematuria
HSP
Tx - supportive, self-limiting condiiton
Macroscopic haematuria in kid 1-2 days after URTI
IgA Nephropathy
Tx - supportive -> ACEi -> SteroidsC
Causes of peritonitis in Peritoneal dialysis
Coag-neg Staph Epidermidis (or Staph A)
Tx - Van/teicoplanin + Ceftizidime
Visible heameaturia, proteinuria/oedema, TN, oliguria, recnt URTI
Post-strep Glomeruloneph
Dev 1-2 W following URTI
Blood - raised anti-streptolysin O titre
renal biopsy - immunofluorescence = ‘starry sky’
Immunosupp regime in renal transplant
initial: ciclosporin/tacrolimus with a monoclonal antibody
maintenance: ciclosporin/tacrolimus with MMF or sirolimus
AKI with v high creatinine, Raised CK, hypocal, hyperphos, hyperkal, metab acidosis, myoglobbinuria
Rhabdomyolysis
SEs Spiro
Hyperkal, gynaecomastia
Most common cause of nephrotic syndro in adults
Focal segmented glomerulonephritis
Bloods - hyperlipidaemia
