Associations of IgA nephropathy
URI
Presentation of IgA nephropathy
Hematuria after an URI and a latent period between infection and onset of disease. Serum complement normal.
Presentation of poststrep GN
10-20 days after strep throat or skin infection. Hematuria, HTN, red cell casts, and mild proteinuria.
Presentation of drug-induced acute interstitial nephritis
Fever rash and arthralgia (penicillins, cephalosporins, and sulfas). Peripheral eosinophilia, hematuria, sterile pyuria and eosinophiluria. WBC casts possible.
Presentation of membranoproliferative GN
Hematuria and low complement.
Pathophysiology of Type 1 renal tubular acidosis and lab findings.
Distal; poor H secretion into urine. Urine pH > 5.5, serum K low-normal.
Causes of Type 1 renal tubular acidosis
Genetic disorders, med tox, autoimmune (Sjogrens, RA)
Pathophys of Type 2 renal tubular acidosis and lab findings
(Proximal) Poor bicarb resorption. Urine pH <5.5. Serum K low-normal.
Causes of type 2 RTA
Fanconi syndrome (glycosuria, phosphaturia, aminoaciduria)
Pathophys and lab findings of type 4 RTA
Aldosterone resistance, urine pH <5.5, serum K high.
Causes of type 4 RTA
Obstructive uropathy, CAH
Renal vein thrombosis is a common manifestation of what renal disease?
Membranous glomerulopathy
What is the presentation of renal vein thrombosis?
Abd pain, fever, hematuria,
What are the five primary renal causes of nephrotic syndrome?
FSGS, membranous nephropathy, membranoproliferative GN, IgA nephropathy, MCD
Describe pathophys of renal insufficiency 2/2 multiple myeloma
In 50% of pts, due to obstruction of the distal and collecting tubules by large laminated casts consisting mainly of Bence-Jones proteins. Amyloid deposition and infiltration of the kidneys by plasma cells are commonly seen.
Describe analgesic abuse nephropathy pathophys
Tubulointerstitial disease characterized by focal glomerulosclerosis
Diabetic nephropathy is characterized by what?
Increased extracellular matrix, basement membrane thickening, mesangial expansion, and fibrosis –> microalbuminuria then overt nephropathy
