ICD-10: N00.2
Acute nephritic syndrome with diffuse membranous glomerulonephritis
Additional Information
Description
Acute nephritic syndrome with diffuse membranous glomerulonephritis, classified under ICD-10 code N00.2, represents a specific renal condition characterized by inflammation of the glomeruli, which are the filtering units of the kidneys. This condition is a subtype of acute nephritic syndrome, which encompasses a range of disorders that lead to glomerular inflammation and subsequent renal impairment.
Clinical Description
Definition
Acute nephritic syndrome is primarily defined by a combination of clinical features, including hematuria (blood in urine), proteinuria (excess protein in urine), hypertension (high blood pressure), and edema (swelling due to fluid retention). When this syndrome is associated with diffuse membranous glomerulonephritis, it indicates a specific pathological process where the glomerular capillary walls become thickened due to the deposition of immune complexes, leading to increased permeability and subsequent leakage of proteins into the urine[1].
Pathophysiology
In diffuse membranous glomerulonephritis, the underlying mechanism often involves an autoimmune response or the presence of circulating antibodies that target the glomerular basement membrane. This results in the formation of subepithelial immune complex deposits, which trigger an inflammatory response. The condition can be idiopathic or secondary to other diseases, such as infections, malignancies, or drug reactions[1][2].
Symptoms
Patients with acute nephritic syndrome due to diffuse membranous glomerulonephritis may present with:
- Hematuria: Visible blood in urine or microscopic hematuria.
- Proteinuria: Often significant, leading to nephrotic syndrome features in some cases.
- Edema: Swelling, particularly in the legs, ankles, and around the eyes.
- Hypertension: Elevated blood pressure due to fluid overload and renal dysfunction.
- Oliguria: Reduced urine output in severe cases.
Diagnosis
Diagnosis typically involves a combination of clinical evaluation, laboratory tests, and imaging studies:
- Urinalysis: To detect hematuria and proteinuria.
- Blood tests: To assess kidney function (e.g., serum creatinine, blood urea nitrogen) and to check for underlying causes (e.g., autoimmune markers).
- Kidney biopsy: This may be necessary to confirm the diagnosis and assess the extent of glomerular damage, revealing the characteristic changes associated with membranous glomerulonephritis[2][3].
Management and Treatment
Management of acute nephritic syndrome with diffuse membranous glomerulonephritis focuses on addressing the underlying cause, controlling symptoms, and preventing complications:
- Medications: Corticosteroids and immunosuppressive agents may be used to reduce inflammation and immune response.
- Blood pressure control: Antihypertensive medications are crucial to manage hypertension.
- Diuretics: To alleviate edema and fluid overload.
- Dietary modifications: A low-sodium diet may be recommended to help manage fluid retention.
Prognosis
The prognosis for patients with acute nephritic syndrome due to diffuse membranous glomerulonephritis varies. Some patients may experience complete recovery, while others may progress to chronic kidney disease or end-stage renal failure, particularly if the underlying cause is not effectively managed[3].
Conclusion
ICD-10 code N00.2 encapsulates a significant renal condition that requires prompt diagnosis and management to mitigate potential complications. Understanding the clinical features, diagnostic criteria, and treatment options is essential for healthcare providers to optimize patient outcomes in those affected by acute nephritic syndrome with diffuse membranous glomerulonephritis. Regular follow-up and monitoring are critical to ensure effective management and to address any evolving renal issues.
Clinical Information
Acute nephritic syndrome with diffuse membranous glomerulonephritis, classified under ICD-10 code N00.2, is a significant renal condition characterized by a combination of clinical features, signs, symptoms, and specific patient characteristics. Understanding these aspects is crucial for diagnosis and management.
Clinical Presentation
Acute nephritic syndrome typically presents with a constellation of symptoms that arise due to inflammation of the glomeruli, the filtering units of the kidneys. In the case of diffuse membranous glomerulonephritis, the following clinical features are commonly observed:
Signs and Symptoms
-
Hematuria: The presence of blood in the urine is a hallmark of nephritic syndrome. Patients may notice dark, tea-colored urine due to the presence of red blood cells[1].
-
Proteinuria: While nephritic syndrome is characterized by less proteinuria compared to nephrotic syndrome, patients may still exhibit significant protein levels in the urine, often detectable through urine dipstick tests[2].
-
Edema: Swelling, particularly in the lower extremities, face, and abdomen, is common due to fluid retention. This occurs as a result of decreased kidney function and altered fluid balance[3].
-
Hypertension: Elevated blood pressure is frequently observed in patients with acute nephritic syndrome, contributing to the overall clinical picture[4].
-
Oliguria: A reduction in urine output may occur, indicating impaired kidney function. This can be a critical sign of worsening renal status[5].
-
Fatigue and Malaise: Patients often report general feelings of tiredness and unwellness, which can be attributed to the systemic effects of kidney dysfunction[6].
Patient Characteristics
Certain demographic and clinical characteristics may predispose individuals to develop acute nephritic syndrome with diffuse membranous glomerulonephritis:
-
Age: This condition can occur in individuals of any age but is more commonly diagnosed in adults, particularly those in middle age[7].
-
Gender: There is a slight male predominance in cases of membranous glomerulonephritis, although both genders can be affected[8].
-
Underlying Conditions: Patients with a history of autoimmune diseases (such as lupus), infections (like hepatitis B or C), or malignancies may be at higher risk for developing this condition[9].
-
Ethnicity: Some studies suggest that certain ethnic groups may have a higher incidence of glomerular diseases, including membranous glomerulonephritis[10].
Conclusion
Acute nephritic syndrome with diffuse membranous glomerulonephritis presents a complex clinical picture characterized by hematuria, proteinuria, edema, hypertension, and oliguria. Recognizing these signs and symptoms, along with understanding patient demographics and underlying conditions, is essential for timely diagnosis and effective management. Clinicians should remain vigilant for these indicators, particularly in at-risk populations, to ensure appropriate intervention and care.

Treatment Guidelines
Acute nephritic syndrome with diffuse membranous glomerulonephritis, classified under ICD-10 code N00.2, is a condition characterized by inflammation of the glomeruli in the kidneys, leading to symptoms such as hematuria (blood in urine), proteinuria (excess protein in urine), edema, and hypertension. The management of this condition typically involves a combination of pharmacological and supportive therapies aimed at addressing the underlying causes, alleviating symptoms, and preventing complications.
Standard Treatment Approaches
1. Pharmacological Management
Corticosteroids
Corticosteroids are often the first line of treatment for patients with membranous glomerulonephritis. They help reduce inflammation and immune response, which can alleviate symptoms and prevent further kidney damage. Commonly used corticosteroids include prednisone or methylprednisolone, administered in varying doses depending on the severity of the condition and the patient's response to treatment[1].
Immunosuppressive Agents
In cases where corticosteroids alone are insufficient, additional immunosuppressive agents may be prescribed. These can include:
- Cyclophosphamide: Often used in conjunction with corticosteroids for more severe cases.
- Calcineurin Inhibitors: Such as cyclosporine or tacrolimus, which can help reduce proteinuria and improve kidney function.
- Rituximab: A monoclonal antibody that targets CD20 on B cells, used in refractory cases[2].
2. Management of Symptoms and Complications
Control of Hypertension
Hypertension is a common complication of nephritic syndrome. Antihypertensive medications, particularly angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs), are often used to manage blood pressure and reduce proteinuria[3].
Diuretics
Diuretics may be prescribed to manage edema and fluid overload, helping to alleviate symptoms of swelling and hypertension. Loop diuretics, such as furosemide, are commonly used in these cases[4].
3. Supportive Care
Dietary Modifications
Patients may benefit from dietary changes, including:
- Low-sodium Diet: To help control blood pressure and reduce fluid retention.
- Protein Restriction: In cases of significant proteinuria, a moderate protein intake may be recommended to reduce the burden on the kidneys[5].
Monitoring and Follow-Up
Regular monitoring of kidney function, electrolytes, and protein levels in urine is essential to assess the effectiveness of treatment and make necessary adjustments. Follow-up visits with a nephrologist are crucial for ongoing management and to address any emerging complications[6].
4. Addressing Underlying Causes
If the membranous glomerulonephritis is secondary to an underlying condition (such as infections, malignancies, or autoimmune diseases), treating the primary cause is essential. This may involve antibiotics for infections or specific therapies for autoimmune disorders[7].
Conclusion
The treatment of acute nephritic syndrome with diffuse membranous glomerulonephritis (ICD-10 code N00.2) is multifaceted, focusing on reducing inflammation, managing symptoms, and addressing any underlying conditions. A tailored approach, often involving a combination of corticosteroids, immunosuppressive agents, and supportive care, is essential for optimal patient outcomes. Regular monitoring and follow-up are critical to ensure effective management and to mitigate potential complications associated with this condition.
