This article reviews nephrotic syndrome in the pediatric population, with special attention paid to minimal change nephrotic syndrome (MCNS).Nephrotic syndrome can affect children of any age, from infancy to adolescence, and is most commonly seen among school-aged children and adolescents. Kayali F, Stein PD. It can coexist with NS when it is caused by the same factors that lead to edema and proteinuria, such as lupus nephritis and drug-induced interstitial nephritis.Acute allergic interstitial nephritis secondary to use of various drugs, including diureticsAcute tubular necrosis caused by volume depletion or sepsisHemodynamic response to nonsteroidal anti-inflammatory drugs, angiotensin-converting enzyme inhibitors, or angiotensin receptor blockersTransformation of underlying glomerular disease (e.g., crescentic nephritis superimposed on membranous nephropathy)Acute allergic interstitial nephritis secondary to use of various drugs, including diureticsAcute tubular necrosis caused by volume depletion or sepsisHemodynamic response to nonsteroidal anti-inflammatory drugs, angiotensin-converting enzyme inhibitors, or angiotensin receptor blockersTransformation of underlying glomerular disease (e.g., crescentic nephritis superimposed on membranous nephropathy)Elevated lipid levels (potentially markedly elevated) are a common feature of NS. Goals of treatment are to reduce proteinuria to normal levels thereby reducing symptoms and risk of complications. Any subtype of lipoprotein concentrations can be elevated.

The pathophysiology of edema formation in the nephrotic syndrome. All rights Reserved. – Primary or idiopathic NS is the most common cause of NS in children between 1 and 10 years. Case records of the Massachusetts General Hospital. If your kidney specialist thinks the risk of a blood clot is extremely high, treatment with warfarin may be recommended to prevent a blood clot. Sha ZH, A 29-year-old pregnant woman with the nephrotic syndrome and hypertension. Quantitative measurement of protein excretion is normally based on a timed 24-hour urine collection. (The kidney uses a complex filtration system known as the glomerular filtration barrier (GFB). There are no recent epidemiologic data to indicate how common or severe this complication is, and no recent data regarding the impact of treatment for dyslipidemia associated with NS. Arterial thrombosis is rare in patients with NS.In a historical case series of patients with NS, venous thrombosis of the lower limb occurred in 8% of patients, and renal venous thrombosis occurred in up to 25% of patients.

However, resolving proteinuria and any underlying disease process is believed to improve or resolve the dyslipidemia.Management of NS is limited by a lack of clear evidence-based guidelines, although recent expert consensus guidelines provide useful recommendations.Because of the possible pathophysiologic role of sodium retention, some experts recommend that routine treatment of patients with NS include restricting dietary sodium to less than 3 g per day and restricting fluid to less than 1,500 mL per day.Patients with nephrosis are resistant to diuretics, even if the glomerular filtration rate is normal.

Ascites, periorbital edema, hypertension, and pleural effusion are also possible presenting features. If the urine test confirms nephrotic syndrome, a kidney specialist will then be involved, and further blood … Nephrotic syndrome (NS) consists of peripheral edema, heavy proteinuria, and hypoalbuminemia, often with hyperlipidemia. Jiang L. Wu T, It is usually associated with typical skin and hair changes (see Kwashiorkor: – Once SAM is excluded, the following two criteria must be met to make a clinical diagnosis of primary NS:– Perform all necessary laboratory tests to exclude secondary NS.– Corticosteroids (prednisolone or prednisone) are indicated in primary NS.– Intravascular volume depletion potentially leading to shock, present despite oedematous appearanceSpecialized advice and management (including further investigations such as renal biopsy) are required:In case of steroid-resistant NS, when referral is impossible and as a last resort, the following palliative measure may reduce proteinuria and delay renal failure:Nephrotic range proteinuria in children is defined as urinary protein excretion greater than 50 mg/kg daily.
