Abstract:
Membranous nephropathy remains the most common cause of nephrotic syndrome in adults. The common variant is idiopathic membranous nephropathy with no evidence of any known precipitating factors. Membranous nephropathy also occurs as a secondary form in association with inflammatory or neoplastic diseases. Prognosis is mostly favorable as shown by the frequency of spontaneous remissions which averages 30%, although about one-third of patients progress to end-stage renal failure. Risk factors for a poor prognosis include severe proteinuria, hypertension, older age, male gender and impaired renal function. Therapy should include an ACE-Inhibitor and/or angiotensin-II receptor blocker to lower proteinuria (blood pressure < or =130/80 mmHg). The majority of patients should be observed for six months whilst receiving conservative treatment before deciding about an immunosuppressive approach. The debate over its management continues today. Steroids alone are ineffective. Evidence-based medicine supports the use of cyclosporine or the Ponticelli regimen (monthly cycling routine of chlorambucil or cyclophosphamide alternating with prednisone).
Insights
Membranous nephropathy, a common cause of adult nephrotic syndrome, often resolves spontaneously. However, some patients progress to end-stage renal failure, necessitating careful management strategies.
Area of Science:
- Nephrology
- Internal Medicine
Context:
- Membranous nephropathy is the leading cause of nephrotic syndrome in adults.
- It can be idiopathic or secondary to other conditions like inflammatory or neoplastic diseases.
Purpose:
- To review the current understanding of membranous nephropathy, including its causes, prognosis, and management.
- To discuss evidence-based therapeutic approaches.
Summary:
- Prognosis is generally favorable with a 30% spontaneous remission rate, but one-third may develop end-stage renal failure.
- Risk factors for poor prognosis include proteinuria, hypertension, older age, male gender, and impaired renal function.
- Treatment involves ACE inhibitors/ARBs for proteinuria, with immunosuppression (cyclosporine or Ponticelli regimen) considered after conservative management.
Impact:
- Provides a comprehensive overview of membranous nephropathy for clinicians.
- Highlights the importance of risk stratification and evidence-based treatment selection.
- Informs therapeutic decisions regarding immunosuppressive therapy versus conservative management.

Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous capillaries...
