  33. 33. SUMMARY Sufiah, a 13 months Cambodian girl was referred to the hospital with complaints of generalized swelling especially at her periorbital area and abdomen which started 3 days prior to admission. Her urine appeared cloudy, dark in colour and little in amount. Physical examination revealed generalized oedema with positive shifting dullness and fluid thrills.
  34. 34. PROVISIONAL DIAGNOSIS Nephrotic syndrome based on: Presence of generalised oedema Cloudy urine Oligouria Fluid thrills Positive shifting dullness Toddler age Weight gain (8 kg- 8.6 kg)
  35. 35. DIFFERENTIAL DIAGNOSIS Points to support Points to against Acute gromerulonephritis -Generalized oedema -Dark urine -Oligouria -Fluid thrills -Positive shifting dullness -Toddler age Cardiac failure -Generalized oedema -Fluid thrills -Positive shifting dullness -Dark urine -Oligouria -Hypertension -Clubbing -Crepitations

  40. 40. Antistreptolysin O titre- to exclude post streptococcus glomerulonephritis Anti-nuclear factor to exclude SLE Serum complement (C3 and C4) to exclude post infectious glomerulonephritis and SLE.
  41. 41. FINAL DIAGNOSIS Idiopathic Nephrotic Syndrome
  42. 42. On admission : MEDICATION Syrup penicillin V 125mg BD Tablet prednisolone 25mg OD IV albumin 20% 5 ml/kg over 2 hours IV frusemide 1 mg/kg OD Monitor Nephrotic Chart : Daily weight, Blood Pressure, Urine protein, Fluid intake
  43. 43. Nephrotic Syndrome Definition A collection of signs associated with glomerular disorders characterized by: massive proteinuria (>3.5 g/day), hypoalbuminemia (serum albumin levels <2.5 g/dL) hyperlipidemia ( >250 mg/dL) 4) generalized edema
  44. 44. Classification Nephrotic syndrome Primary/ Idiopathic Secondary Minimal change disease Membranous GN Focal segmental glomerulosclerosis Membranoproliferative GN IgA nephropathy Diabetes Mellitus Amyloidosis Systemic lupus erythematosus Ingestion of drugs (lithium, penicillamine,”street heroin”) Infections (malaria, syphilis, hepatitis B, HIV) Malignancy ( carcinoma, melanoma) Miscellaneous (bee-sting allergy, hereditary nephritis) Congenital Present during the first 6 months life Finnish type is an autosomal recessive disorder most common in Scandinavian and due to mutation in component protein in the glomerulus filtration slit. Diffuse mesangial sclerosis which is a heterogenous group of abnormalities.
  45. 45. Inflammatory reaction Derangement in capillary walls of glomeruli Increase permeability to plasma protein Proteinuria Allows protein to escape from plasma into glomerular filtrate Drop in plasma colloid osmotic pressure Fluid escapes into tissues Edema Pathophysiology of Nephrotic Syndrome
  46. 46. Periorbital edema (earliest sign) Scrotal or vulval, leg, ankle edema Weight gain Abdominal pain (Ascites) Respiratory distress (Pleural effusion) Malaise Diarrhea Nelson Essential Paediatrics Illustrated Textbook of Paediatrics CLINICAL MANIFESTATION
  47. 47. Urine protein – on test strips FBC and ESR Renal profile – urea, electrolyte, creatinine Serum cholesterol LFT - albumin Complement level Antistreptolysin O titre and throat swab Nelson Essential Paediatrics Paediatric Protocols INVESTIGATIONS
  48. 48. Imaging Studies Ultrasound Pulsed doppler studies Void cysturethrogram (VCUG) IV pyelogram MRI CT Diagnostic Studies First morning specimen :Urine protein-to-creatinine ratio (normal : <0.2) Serum C3 complement level RENAL BIOPSY : only indicated if a child does not respond to the prednisolone therapy within 4 weeks.
  49. 49. MANAGEMENT Bed rest Diet – adequate calories ,normal protein diet with salt restriction Antibiotic – penicillin V BD during relapse Fluid status : assess for hemodynamic status. ( underfilling or overfilling ) Diuretic therapy Human albumin 25% parenterally with IV loop diuretic ( frusemide ) to produce diuresis
  50. 50. Cortocosteroid Therapy Effective in inducing remission of NS Remission – urine dipstick is trace or nil for 3 consecutive days Relapse – urine albumin excretion > 40 mg /m²/hr OR urine dipstix 2+ or > for 3 consecutive days Frequent Relapses - Two or more relapses within 6 months of initial response or - 4 or more relapses within any 12 month period Cyclophosphamide therapy indicated for child who show signs of steroid toxicity
  51. 51. Initially -60 mg/m²/day for 4 weeks Prednisolone 40 mg/m²/alternate day for 4 weeks then taper at 25% monthly over 4 month 1. Response Prednisolone 60 mg/m²/day till remission 40 mg/m²/alternate day for weeks then stop 2. RELAPSE Reinduce (2), then taper & keep low dose alternate day prednisolone 0.1-0.5 mg/kg/dose for 6 month 3. Frequent relapse Treat as (3) if not steroid toxic, consider cyclophosphamide if steroid toxic 4. Relapse while on prednisolone 2-3 mg/kg/day for 8-12 weeks (cumulative dose 168 mg/kg 5. Oral cyclophosphamide -not steroid toxic: treat as 2 & 3 - If steroid toxic  paeds nephro 6. Relapse post cyclophosphamide No response Renal biopsy
  52. 52. 1. Infection- bacteremia and peritonitis – patient with relapse have high risk of infection with capsulated bacteria esp pneumococus / E.coli 2. Side effect of steroid 3. Hypovolemia – result from use of diueresis or diarrhea 4. Hypercoagulable state with risk of tromboembolism – d/t loss of protein -> urinary lose of antithombin, thrombocytosis (steroid therapy) -> increase synthesis of clotting factor and increased blood viscosity ->predispose to thrombosis

  54. 54. MINIMAL CHANGES DISEASES. Relatively benign disorder. Most frequent cause of NS in children(1-7 years). Clinical features Insidious development of NS. No hypertension and preserved renal function. Good prognosis. CAUSES
  55. 55. NEPHRITIC SYNDROME Nephritic syndrome is defined by: hematuri a (usually with dysmorphic RBCs), and hypertension , oliguria (400 mL/day of urine). Uremia - due to retention of waste products Azotemia (elevated blood nitrogen) Or come with symptom of underlying problems Triad of sinusitis, pulmonary infiltrates, and nephritis suggesting Wegener granulomatosis Nausea/vomiting, abdominal pain, and purpura observed with Henoch-Schönlein purpura A rthralgia s associated with systemic lupus erythematosus (SLE) Hemoptysis occurring with Goodpasture syndrome or idiopathic progressive glomerulonephritis Skin rashes observed with a hypersensitivity vasculitis or systemic lupus erythematosus; also possibly due to the purpura that can occur in hypersensitivity vasculitis, cryoglobulinemia, and Henoch-Schönlein purpura
  56. 56. Causes of Nephritic Syndrome Post streptococal AGN Post infectious AGN Henoch schonlein perpura IgA nephropathy SLE Systemic vasculitis
  57. 57. Focal Segmental Glomerulosclerosis Lesion characterized histologically by sclerosis. Pathogenesis is unknown. Clinical course: Little tendency for spontaneous remission of idiopathic FSGS. Poor respond to steroid therapy. Bad prognosis. CAUSES
  58. 58. Management Nephrotic Nephritic Normal protein diet No added salt when edema Penicillin V at diag. & during relapse esp. with gross edema Diuretics is not necessary when steroid responsive Human albumin-in grossly edematous Hemodynamic status - Check for sign of hypervolamia or hypovolaemia Strict monitoring-luid intake, urine output, daily weight, BP chart Fluid restriction during oligouric phase Diuretics Look for complication of post strep AGN – hypertensive encephalopathy (usu. seizure), pulm edema (lft.vent failure), acute renal failure
  59. 59. Nephrotic vs nephritic Nephrotic syndrome: 1. Massive proteinuria 2. Hypoalbuminemia 3. Edema 4. Hyperlipidemia/hyperlipiduria Nephritic syndrome: 1. Hematuria 2. Oliguria 3. Azotemia 4. Hypertension
  60. 60. Side effects of steroids: Increased body weight Muscle wasting Growth retardation in children Cutaneous striae Hypertension Increased susceptibility to infections Delayed wound healing Hirsutism Osteoporosis Diabetes peptic ulcer cataract
