PRECIPITATING FACTORS

Lifestyle

High sodium and protein diet

Exposure to Group A Beta Hemolytic streptococcus

Deposition of antigen-antibody complex in glomerulus

Leukocytes infiltrate the glomerulus

Increased production of epithelial cells lining the

glomerulus

If not treated

Passage of protein in the nephrons

Damage nephrons allow the passage of large molecules like

RBC

hematuria

Thickening of the glomerular filtration membrane

Renal damage especially the nephrons

Antigen-antibody product

Antigen

Group A Beta Hemolytic streptococcal

(Sore throat, impetigo, viral infection)

proteinuria

Edema or anasarca

Decrease osmotic pressure

IgG combines with host antibodies

Streptococcal neuraminidase may alter host immunoglobulin

G (IgG)

Scarring and loss of glomerular filtration membrane

Hypertension

Renin angiotensin II promotes vasoconstriction

Decrease of blood flow and affects the Renin-Angiotensin-

aldosterone-system

Decrease in circulating blood volume

IgG/anti-IgG immune complex are formed and then collect in

the glomeruli

Decreased glomerular filtration rate (GFR)

Acute glomerulonephritis

Alteration in excretion of sodium

Inflammation of glomerular cap

If treated

MEDICATION:

Antibiotic drugsHigh dose CorticosteroidImmunosuppressantLoop diuretic medicationsAntihypertensive agentsCytotoxic agents

Progresses towards renal failure

Result in kidney death

Abnormal urinalysis (microhematuria)

PROGNOSIS:

With aggressive treatment,

patient with rapidly

progressive glomerulonephritis is

greatly improved.

DIET:

Dietary protein and sodium restriction

Severe hypertensionEncephalopathyPulmonary edema

Hypertensive retinopathyHypertensive encephalopathyRapidly progressive glomerulonephritisChronic renal failureNephrotic syndrome

End-organ damage in the central nervous system and cardiopulmonary system

Clinical manifestations:

HeadacheMalaiseFlank painCirculatory overloadEngorged neck veinCardiomegaly

DEATH

PROCEDURES:

bed restPlasma exchange (plasmapheresis)Dialysis
