Renal Disease Flashcards
Most often are IMMUNE-MEDIATED
Glomerular
Result from INFECTIOUS or TOXIC SUBSTANCES
Tubular and Interstitial
Causes a renal perfusion that subsequently induces both MORPHOLOGIC & FUNCTIONAL changes in the kidney
Vascular
Glomerular Disease characterized by INCREASED permeability of the GLOMERULI to the passage of plasma proteins (ALBUMIN)
Nephrotic Syndrome
Amount of protein in Heavy Proteinuria
3.5g/day
Plasma albumin usually <3g/dL → LIVER SYNTHESIS unable to compensate for the large amount of protein EXCRETED in the urine
Hypoproteinemia
INCREASED plasma levels of TRIGLYCERIDES, CHOLESTEROL, PHOSPHOLIPIDS & VLDL
Hyperlipidemia
Caused by Post-Streptococcal Infection → known as: ACUTE POSTSTREPTOCOCCAL GLOMERULONEPHRITIS
(Blood: Elevated ASO titer)
Acute Glomerulonephritis
Causative agent of Acute glomerulonephritis and the protein found that induces this type of nephritis
Group A Beta-hemolytic Streptococci / M protein
Non-streptococcal (bacteria: pneumococci; virus: mumps and Hepa B; parasitic infection: Malaria)
SCLEROSIS of the GLOMERULI
Focal Segmental Glomerulonephritis
Predominant feature of Focal Segmental Glomerulonephritis
Proteinuria
Cellular Proliferation of the MESANGIUM along with LEUKOCYTE INFILTRATION & THICKENING OF THE GLOMERULAR BASEMENT MEMBRANE
Membranoproliferative Glomerulonephritis
Most prevalent type of glomerulonephritis world wide
Deposition of IgA in the GLOMERULAR MESANGIUM
IgA Nephropathy
Development: Slow and Silent
80%: have previously some form of glomerulonephritis
20%: form of glomerulonephritis that has been unrecognized
Chronic Glomerulonephritis
Destruction of RENAL TUBULAR Epithelial Cells
Acute Tubular Necrosis
Type of Acute Tubular Necrosis follows a HYPOTENSIVE event that result in decrease perfusion of the kidneys followed by renal tissue ischemia
ISCHEMIC ATN
Give the 3 Principal causes of Ischemic ATN
-Sepsis
-Shock
-Trauma
Type of Acute Tubular Necrosis results from exposure to NEPHROTOXIC AGENTS
TOXIC ATN
Normal solutes or substances that become toxic when their concentration in the bloodstream is excessive
Endogenous Nephrotoxin
Examples of Endogenous Nephrotoxin
Hemoglobin, Myoglobin, Uric acid, Immunoglobulin light chain
Nephrotoxin that are substances ingested or absorbed
Exogenous Nephrotoxin
Examples of Exogenous Nephrotoxin
Therapeutic agents, anesthetics, Radiographic contrast media, Chemotherapeutic drugs, Recreation drugs, Industrial chemicals
