Nephrotic Syndrome Care
Nephrotic Syndrome Treatment in Secunderabad — Massive Protein Loss, Expert Diagnosis, Life-Changing Complications Prevented
If you — or your child — has woken up with dramatically swollen legs, puffy eyes, and frothy urine, and a blood test or urine test has confirmed high levels of protein in the urine, you may be experiencing nephrotic syndrome. This is a condition in which the kidneys' filtering units are so damaged that large amounts of protein — which should stay in the blood — spill into the urine. As albumin (the key protein that keeps fluid in blood vessels) drains away, fluid leaks into surrounding tissues and causes the severe swelling that is nephrotic syndrome's most visible feature.
At KIMS Secunderabad, nephrotic syndrome is managed by DM-qualified nephrologists for adults and by our paediatric renal team for children. The approach differs by age — adults require a kidney biopsy to identify the specific underlying cause and choose the correct immunosuppressive regimen; children are usually treated initially with steroids without biopsy, since the most common cause in childhood responds predictably. The complications of nephrotic syndrome — particularly blood clots and serious infections — are actively monitored and prevented as part of every patient's care programme at KIMS.
At a glance
Condition
Nephrotic Syndrome — a clinical syndrome of massive protein loss from the kidneys
Four defining features
1. Heavy proteinuria (>3.5 g/day) · 2. Low blood albumin (hypoalbuminaemia) · 3. Oedema (severe swelling) · 4. High cholesterol (hyperlipidaemia)
What causes the protein loss?
Damage to the kidney's filtering units (glomeruli) — caused by glomerulonephritis (membranous, FSGS, minimal change) or systemic disease (diabetes, lupus)
Adults: diagnosis requires
Kidney biopsy — to identify the specific underlying glomerular disease and choose the right immunosuppression
Children: most common cause
Minimal change disease — accounts for >75% of childhood cases. Usually responds rapidly to steroids without needing a biopsy.
⚠ Serious Complication
Blood clots (DVT, pulmonary embolism, renal vein thrombosis) — caused by protein loss affecting the blood's clotting balance. Requires anticoagulation in high-risk patients.

What is nephrotic syndrome? Understanding the triad
Nephrotic syndrome is not a single disease — it is a clinical syndrome defined by four features occurring together, all caused by the same underlying mechanism: damage to the glomerular basement membrane, allowing massive amounts of protein to escape from the blood into the urine.
| Feature of Nephrotic Syndrome | Why it happens and what it causes |
|---|---|
| Heavy proteinuria (> 3.5 g/day — often 5–20+ g) | Damaged glomerular filters allow albumin and other proteins to escape into urine — causing frothy or foamy urine. Protein depletion from blood drives all other features. |
| Low albumin (hypoalbuminaemia — serum albumin < 25 g/L) | Albumin is lost in urine faster than the liver can replace it. Albumin normally holds fluid in blood vessels — when it falls, fluid leaks into surrounding tissues. |
| Severe oedema (swelling) | Fluid redistributes from blood into tissues as albumin falls. Facial puffiness around the eyes (worse in morning) · Leg, ankle, foot swelling · Abdominal fluid (ascites) · Breathlessness (pleural effusion) in severe cases. |
| Hyperlipidaemia (high cholesterol and triglycerides) | Low albumin triggers the liver to produce more proteins — including lipoproteins. Elevated LDL cholesterol · Cardiovascular risk if prolonged · Xanthelasma (white cholesterol deposits around eyes) in chronic cases. |
What causes nephrotic syndrome? — adults vs children
The underlying cause of nephrotic syndrome varies significantly by age. Understanding these differences is critical because it determines whether a kidney biopsy is necessary and what medication protocol will be most effective.
In adults
In adults, the most common primary (kidney-specific) causes of nephrotic syndrome requiring biopsy-guided diagnosis are: • Membranous Nephropathy — the most common cause in adults over 40. Associated with anti-PLA2R antibodies in approximately 70% of primary cases. Presents with heavy proteinuria, often without haematuria. Treated with rituximab (now international first-line) or cyclophosphamide-based regimens. • Focal Segmental Glomerulosclerosis (FSGS) — scarring of segments of some glomeruli. A common cause of nephrotic syndrome in younger and middle-aged adults, and the leading cause of CKD from nephrotic syndrome. Treated with steroids first; tacrolimus, cyclosporin, or rituximab for steroid-resistant cases. • Minimal Change Disease — accounts for approximately 10–15% of adult nephrotic syndrome. Despite its name, the prognosis is good with treatment — over 80% respond to steroids. Biopsy is performed to confirm the diagnosis and exclude FSGS. • Secondary causes — the most important are: diabetic nephropathy (the most common secondary cause globally), lupus nephritis (Class V membranous lupus), amyloidosis, and medications (NSAIDs, gold, penicillamine).
In children
Childhood nephrotic syndrome is different from adult nephrotic syndrome — and significantly more manageable. Minimal change disease accounts for over 75% of childhood cases. Children with minimal change disease have glomeruli that appear almost entirely normal on electron microscopy — but respond dramatically to a simple steroid course. Most children with first-episode nephrotic syndrome are treated with prednisolone without a kidney biopsy. Over 90% achieve complete remission within 4 to 8 weeks. Kidney biopsy in children is reserved for: those who do not respond to steroids (steroid-resistant), those with unusual features (haematuria, impaired kidney function, hypertension at presentation), those requiring a second-line immunosuppressant, and adolescents where FSGS is more likely. If your child has their first episode of nephrotic syndrome, they will almost certainly be treated with steroids first, without a biopsy. If they respond (urine protein disappears within 4–8 weeks), they have minimal change disease and the prognosis is excellent. If they relapse frequently, KIMS offers comprehensive management of frequently relapsing and steroid-dependent childhood nephrotic syndrome.
The complications of nephrotic syndrome — what patients must know
Nephrotic syndrome's complications are more serious than most patients realise. Managing the underlying protein loss is only part of the treatment — preventing these complications is equally important and requires active, structured specialist monitoring.
Blood clots (Venous Thromboembolism)
This is the most dangerous and least understood complication. As albumin and other proteins are lost in urine, the clotting balance shifts—anticoagulant proteins are lost while clot-promoting factors are retained. The result: hypercoagulable blood. Patients with heavy nephrotic syndrome—particularly membranous nephropathy—have a significantly elevated risk of DVT, pulmonary embolism, and renal vein thrombosis. At KIMS, every patient is assessed for anticoagulation, and high-risk patients receive prophylactic therapy.
Serious infections
Immunoglobulins (antibodies) are lost in the urine—leaving patients significantly immunocompromised. Spontaneous bacterial peritonitis, pneumococcal pneumonia, and septicaemia are all significantly more common. At KIMS, all nephrotic patients receive pneumococcal and influenza vaccination. Children often receive prophylactic oral penicillin for at least 1 year. Any fever is investigated urgently rather than assumed to be viral.
Hyperlipidaemia & cardiovascular disease
High cholesterol and triglycerides in nephrotic syndrome significantly increase cardiovascular risk—particularly in membranous nephropathy where the syndrome may persist for years. At KIMS, statin therapy is initiated for persistent hyperlipidaemia, and cardiovascular risk is formally assessed at each clinic review to protect long-term heart health.
Acute kidney injury (AKI)
Severe hypoalbuminaemia reduces the effective blood volume circulating to the kidneys, which can trigger pre-renal AKI—especially if diuretics are given too aggressively or if the patient becomes dehydrated. Regular kidney function monitoring at KIMS includes renal function assessment alongside every urine protein measurement to prevent sudden decline.
Treatment at KIMS — cause-specific and complication-focused
Treatment has two parallel tracks — treating the underlying cause (to stop protein loss) and managing the complications (to prevent harm while the underlying cause is being treated).
Treating the oedema — diuretic therapy
Diuretics (furosemide, with or without spironolactone) remove the excess fluid causing oedema. This is symptomatic treatment — it does not treat the underlying protein loss. At KIMS, diuretics are titrated carefully to avoid excessive fluid removal, which can cause AKI. Salt restriction (under 2g sodium per day) is an essential co-intervention — a low-salt diet dramatically reduces the fluid load the diuretics need to manage.
Treating the underlying cause — immunosuppression
For adult nephrotic syndrome requiring immunosuppression — the protocol is matched precisely to the biopsy-confirmed diagnosis. • Minimal change disease: standard prednisolone (1 mg/kg/day). • Membranous nephropathy: rituximab for primary cases (now international first-line). • FSGS: prednisolone with calcineurin inhibitors (tacrolimus or cyclosporin) or rituximab for steroid-resistant cases. • Lupus nephritis Class V: mycophenolate mofetil combined with hydroxychloroquine. At KIMS, all patients on long-term immunosuppression receive infection prophylaxis (co-trimoxazole for pneumocystis prevention in cyclophosphamide-treated patients) and bone protection (calcium, vitamin D, bisphosphonate where needed for steroid-related osteoporosis).
Managing relapse — when nephrotic syndrome returns
Nephrotic syndrome — particularly minimal change disease — frequently relapses after steroid-induced remission. Categories of response guide treatment escalation. • Frequently relapsing disease (2+ relapses within 6 months): low-dose maintenance steroids or steroid-sparing agents (mycophenolate, tacrolimus, levamisole for children). • Steroid-dependent disease: requires continuous or near-continuous steroids to maintain remission — mycophenolate or tacrolimus are used to allow steroid tapering. • Steroid-resistant disease: calcineurin inhibitors, rituximab. At KIMS, relapse patterns are tracked from the first episode and treatment is escalated proactively.
Why choose KIMS Secunderabad for nephrotic syndrome?
Biopsy-guided adult management
Adult nephrotic syndrome treated without a biopsy is frequently undertreated or mistreated. KIMS performs ultrasound-guided kidney biopsies with NABL-accredited pathology, providing the precise diagnosis—such as Membranous Nephropathy or FSGS—that determines the correct immunosuppressive regimen.
Dedicated paediatric renal team
Children are managed by KIMS's paediatric nephrology team using age-appropriate steroid protocols, growth monitoring, and family education for home dipstick testing. Paediatric dosing and monitoring are fundamentally different from adult nephrology and require this specialist focus.
Rituximab for complex cases
Rituximab is now a cornerstone for steroid-resistant or frequently relapsing cases. KIMS administers and monitors these monoclonal antibody infusions within the hospital, including pre-medication protocols and post-infusion B-cell count monitoring to guide precision re-dosing.
Active blood clot prevention
Clot risk is formally assessed at each visit (serum albumin, proteinuria level, mobility). High-risk patients, particularly those with Membranous Nephropathy and albumin below 20 g/L, receive prophylactic anticoagulation with low molecular weight heparin or warfarin, monitored by our team.
Cause-specific immunosuppression
We avoid 'one-size-fits-all' treatments. Whether it is mycophenolate for Lupus Nephritis or calcineurin inhibitors for FSGS, our protocols are matched to biopsy results and include essential prophylaxis for infection and bone health.
Structured follow-up & relapse tracking
Nephrotic syndrome often returns. We track relapse patterns from the very first episode to escalate treatment proactively—moving to steroid-sparing agents early to prevent the long-term side effects of chronic steroid use.

Frequently Asked Questions
Foamy or frothy urine combined with severe swelling (particularly of the legs, ankles, and face) are the two most characteristic symptoms of nephrotic syndrome. The foam is caused by protein in the urine — protein creates surface tension that forms persistent bubbles in water. The swelling occurs because massive protein loss from the blood lowers serum albumin, which normally holds fluid within blood vessels. As albumin falls, fluid leaks into surrounding tissues — the legs, face, and in severe cases the abdomen and around the lungs. Both symptoms indicate that the kidneys are leaking large amounts of protein and require urgent nephrology assessment. Call KIMS on 040 - 44885000.
Yes — facial puffiness (periorbital oedema), particularly marked in the morning and improving through the day, combined with frothy urine and leg swelling, is a classic presentation of childhood nephrotic syndrome. In children, the most common cause (over 75% of cases) is Minimal Change Disease, which responds rapidly and dramatically to steroid treatment — most children are back to normal within 4 to 8 weeks. KIMS's paediatric renal team manages childhood nephrotic syndrome with age-appropriate steroid protocols, vaccination, home urine dipstick monitoring, and family education. Your child does not automatically need a kidney biopsy — the KIMS team will assess whether one is needed based on their specific clinical features.
Yes — and this is one of the most serious and least known complications of nephrotic syndrome. As the kidneys leak protein into the urine, the blood loses anticoagulant proteins (protein C, protein S, antithrombin III) that normally prevent blood clots from forming. The result is a hypercoagulable state — an increased tendency to form clots. Patients with nephrotic syndrome are at significantly increased risk of deep vein thrombosis (DVT), pulmonary embolism (PE, a potentially fatal clot in the lungs), and renal vein thrombosis. At KIMS, every nephrotic syndrome patient's clot risk is formally assessed. High-risk patients — those with very low albumin, membranous nephropathy, or limited mobility — receive anticoagulation treatment.
In adults, yes — almost always. Adult nephrotic syndrome has multiple possible causes (membranous nephropathy, FSGS, minimal change disease, diabetic nephropathy, lupus, and others), each requiring a different treatment. Giving the wrong immunosuppression for the wrong cause is ineffective and potentially harmful. A kidney biopsy — performed at KIMS under ultrasound guidance, under local anaesthetic, in approximately 30 to 45 minutes — provides the tissue diagnosis that determines the correct treatment. In children, biopsy is usually not performed for the first episode of nephrotic syndrome, since the most common cause responds to steroids without needing tissue diagnosis. The KIMS team will advise whether a biopsy is needed based on your specific situation.
Relapse is common in nephrotic syndrome — particularly in minimal change disease, which tends to recur throughout childhood and sometimes into adulthood. Approximately 60–70% of children with minimal change disease relapse at least once. Frequent relapsers and steroid-dependent patients require second-line therapy (mycophenolate mofetil, tacrolimus, or rituximab) to maintain remission while reducing steroid exposure. FSGS has variable relapse rates. Membranous nephropathy has approximately 20–30% spontaneous remission rate, with the remainder requiring immunosuppression. At KIMS, all patients are enrolled in a structured relapse monitoring programme with defined criteria for restarting treatment.
The most important dietary modification in nephrotic syndrome is strict salt restriction — under 2 grams of sodium per day (under 5g of salt). Sodium retention is a major driver of oedema in nephrotic syndrome, and a low-sodium diet dramatically reduces the fluid load that diuretics need to manage. For protein intake: moderate (not high) dietary protein is recommended — 0.8–1.0 g/kg body weight — high-protein diets increase urinary protein loss. If potassium is elevated (from ACE inhibitors or kidney dysfunction), high-potassium foods should be limited. The KIMS renal dietitian provides a personalised dietary plan for all nephrotic syndrome patients — not a generic printed sheet.
Duration depends on the underlying cause and the pattern of response. First-episode minimal change disease: steroids for 12–16 weeks total. Membranous nephropathy: rituximab infusion with follow-up B-cell count monitoring — remission may take 6–18 months. FSGS: steroids for 3–6 months; calcineurin inhibitors for 12–24 months for steroid-resistant cases. All patients require long-term nephrology follow-up after remission — monitoring urine protein, kidney function, blood pressure, cholesterol, and vaccination status. At KIMS, the follow-up schedule is defined from the first clinic visit and communicated clearly to the patient and family.
