    Study Notes

    Laboratory Investigations

    • Urinalysis: hematuria, proteinuria
    • Cultures of pharynx: positive for streptococci
    • Serologic tests: Antistreptolysin O (ASO), Antistreptokinase (ASKase)
    • Serum Complement level (C3)

    Incidence

    • Most common in school-aged children
    • Ages of peak incidence: 2 to 6 years
    • Predominantly in boys
    • 60% to 80% have a history of a preceding upper respiratory tract infection or otitis media

    Clinical Features

    • Dark brown-colored / “coke” urine due to blood and protein
    • Hematuria (blood in urine): may be microscopic or macroscopic
    • Proteinuria (primary albumin): due to injury in the glomerular membrane and increased permeability of glomerular membrane
    • Urinalysis: turbid; presence of pus, RBC and protein; specific gravity: >1.035
    • Oliguria: diminished urine output, reduced GFR due to inflammation of glomerular membrane
    • Fluid overload: may have shortness of breath or exercise intolerance
    • High blood pressure: may have alteration in mental status; headaches, visual disturbances, signs of hypertensive encephalopathy
    • Lab tests: elevated urea and serum creatinine level (Renal insufficiency)

    Complications

    • Kidney failure: Loss of function in the filtering part of the nephron may cause waste products to accumulate rapidly

    Medical Management

    • Goal: Reduce inflammation in the kidney, reduce fluid overload, and control blood pressure
    • Fluid restriction
    • Low protein, low salt, and potassium diet
    • Pharmacological interventions: diuretics, anti-hypertensives (ACE inhibitors)

    Nursing Interventions

    • Nursing diagnosis: Risk for electrolyte imbalance, Risk for ineffective renal perfusion, Risk for poor growth, Risk for anemia
    • Expected outcome: Risk of injury related to progression of disease (hypertension)
    • Goal: Patient will gradually have stable BP and not experience any related injury (due to hypertensive encephalopathy)

    Nephrotic Syndrome

    • A collection of symptoms due to kidney damage: proteinuria, edema, hyperlipidemia, and hypoalbuminemia
    • Most common among boys between ages 2 and 6 years old
    • Nephrotic-range proteinuria: > 2 g protein/dl /24 hrs (dipstick 3+ = 2 - 5 g/24hrs)
    • Clinical features: generalized edema, massive proteinuria, hypoalbuminemia, hyperlipidemia, frothy or foamy appearance of urine, weight gain, pale and shiny skin with prominent veins, irritability, anorexia, and malaise

    Pathophysiology of Nephrotic Syndrome

    • Normally, proteins are not excreted in the urine
    • In nephrotic syndrome, some proteins are removed along with waste due to damage to glomeruli
    • On microscopic exam, glomeruli appearance greatly changed
    • Causes: glomeruli inflammation (as autoimmune response), minimal change nephritis

    Laboratory Investigation of Nephrotic Syndrome

    • Urinalysis: protein level is > or equal to 2 g/dL/24hrs, micro-hematuria, elevated specific gravity
    • Serum albumin level < 25 g/dL (hypoalbuminemia)

    Medical Management of Nephrotic Syndrome

    • Medication: corticosteroid therapy (Prednisone @ 2mg/kg/day till no more proteinuria for 3 days), antibiotic therapy after blood and urine C/S

    Nursing Care Management

    • Objectives: identification of child with UTI, education of parents
    • Prevention: perineal hygiene, avoid tight clothing/diapers, avoid ‘holding’ urine, increase fluid intake

    ACUTE GLOMERULONEPHRITIS

    • A common childhood condition: sudden onset of hematuria, proteinuria, and red blood cell (RBC) casts
    • Often accompanied by hypertension, edema, uremia (due to decreased glomerular filtration rate)

    Pathophysiology of Acute Glomerulonephritis

    • History of streptococcal infection about 2 weeks ago
    • Formation of anti-streptococcal antibodies; antigen-antibody complex lodges in the glomerular capillaries
    • Activates the complement system to cause an inflammatory response in the glomeruli of both kidneys
    • Increased capillary permeability and cell proliferation → leakage of some protein and large numbers of erythrocytes into the filtrate
    • Immunoglobulin G and C3 (complement) are present in glomerular tissue and serum C3 is reduced
    • Loss of filtration function of the nephron: reduced glomerular filtration rate → fluid and wastes product retention
    • Decreased blood flow in the kidney - trigger renin secretion which leads to elevated blood pressure and edema
    • Severe prolonged inflammation - scarring of kidneys
