Nephrotic Syndrome Symptoms Causes Treatment of Nephrotic Syndrome

Nephrotic Syndrome


Nephrotic syndrome is characterized by pro­teinuria > 3 to 3.5 g / 24 hrs., Associated with many types of kidney disease hypoalbumin­emia, edema, hyperlipidemia, Iipiduria, and hy­percoagulability. Nephrotic syndrome is a dis­ease of glomerular basement membrane, . podocyte-slit diaphragm. A condition marked by increased glomerular permeability to proteins, resulting in massive loss of proteins in the urine, edema, hypoalbuminemia, hyperlipidemia, and hypercoagulability.

  • are minimal change disease, focal and segmental glomerular sclerosis,
  • · membranous glomerulopathy, membrano-proliferative glomerulonephritis, diabetic nephropathy, and amy­loidosis.
  • Nephrotic syndr.ome responds well to glucocorticoids. The chief feature of nephrotic syndrome is proteinuria. Hypoalbuminemia is due to loss of protein in urine, increased renal ca.tabolism, increased hepatic syn­thesis of albumin. ,
  • Edema is due to hypoalbuminemia, decreased intra­vascular oncotic pressure, leakage of extra cellular fluid (ECF) to interstitial spaces, decrease of intra­vascular volume, activation of renin- angiotensin-al­dosterone axis and the sympathetic nervous system, and release of vasopressin, and suppression of atrial natriuretic peptide release, renal salt and water re­tention.
  • Hyperlipidemia is due to increased hepatic lipopro­tein synthesis, leading to atherosclerosis and wors­ening of renal disease.
  • Hypercoagulability is due to increased urinary loss of antithrombin III, protein C and 5, hyper­fibrinogenemia, increased platelet aggregation. This leads to peripheral arterial and venous thrombosis, renal vein thrombosis, pulmonary thromboembolism.

  • There is protein malnutrition.
  • There is macrocytic hypochromic anaemia .
  • There is hypocalcemia and vitamin D deficiency and secondary hyperparathyroidism. There is also in­creased incidence of infections.

Physical Exam in Nephrotic Syndrome

  • A complete physical exam may discover clues to systemic disease as a potential cause and/or may suggest the severity of disease:
  • Fluid retention: Abdominal distention, abdominal fluid shift, extremity edema, puffy eyelids, scrotal swelling, weight gain, shortness of breath:
  • Pericardial rub and decreased breath sounds with pleural effusions may develop.
  • Hypertension
  • Orthostatic hypotension

History of Nephrotic Syndrome

  • Look for signs or symptoms of systemic disease:
  • Joint complaint, rash, edema, infectious complaint, fevers, anorexia, oliguria, foamy urine, acuteHow to Maintain Fluid & Electrolytes balance. Read more ... » flank pain, hematuria, etc.
  • Look for a recent drug history that may be causative, especially nonsteroidal anti-inflammatory drugs (NSAIDs).
  • Assess for risk factors.
Nephrotic Syndrome Risk Factors
  • Drug addiction (e.g., heroin [FSGS])
  • Hepatitis B and C, HIV, other infections
  • Cancer (usually MGN, may be MCD)
  • Chronic analgesic use/abuse
  • Preeclampsia
  • Immunosuppression
  • Nephrotoxic drugs
  • Vesicoureteral reflux (FSGS)

Symptoms :

  • Patients with nephrotic syndrome may initially present with fluid retention in the legs or symptoms caused by blood clotting (e.g., in the renal vein).
  • The hyperlipidemia that often accompanies the syndrome may lead to symptoms caused by atherosclerosis.

Treatment of Nephrotic Syndrome

Admission Criteria

  • Respiratory distress, sepsis/severe infection, thromboses, renal failure, hypertension, or other complications

Discharge Criteria

  • Hemodynamically stable patients without complications may be managed as outpatients.
