Summary
Cyclophosphamide pulse therapy significantly reduced proteinuria in primary glomerulonephritis patients. This treatment showed effectiveness regardless of kidney biopsy findings and had minimal side effects.
Area of Science:
- Nephrology
- Immunology
- Pharmacology
Background:
- Primary glomerulonephritis is a significant cause of kidney disease.
- Proteinuria is a key indicator of glomerulonephritis severity and progression.
- Current treatments for glomerulonephritis have limitations and potential side effects.
Purpose of the Study:
- To evaluate the efficacy of intravenous cyclophosphamide pulse therapy in patients with primary glomerulonephritis and significant proteinuria.
- To assess the impact of cyclophosphamide pulse therapy on proteinuria levels and renal function.
- To determine if treatment response correlates with specific kidney biopsy findings.
Main Methods:
- 20 patients with primary glomerulonephritis and proteinuria >3.5g were enrolled.
- Patients received intravenous cyclophosphamide (0.75 g/m2) pulses monthly, then quarterly.
- Pretreatment included methylprednisolone and oral prednisone.
Main Results:
- Statistically significant decrease in proteinuria from 12.2 g to 5.3 g (p < 0.05).
- Remission achieved in 3 patients, decreased proteinuria in 11; 6 patients showed no response.
- Creatinine clearance remained stable; no significant complications were observed.
Conclusions:
- Cyclophosphamide pulse therapy is a potentially effective treatment for primary glomerulonephritis.
- Treatment efficacy was independent of the specific histological changes observed in kidney biopsies.
- Further research is warranted to optimize treatment protocols and identify patient subgroups most likely to benefit.

01:21Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids
Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2 (COX-2),...
01:27Acute Pyelonephritis I: Introduction
Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such as Proteus,...
01:28Acute Pyelonephritis II: Diagnostic Studies and Management
Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...
01:24Nephrotic Syndrome I : Introduction
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of fluid...

Nursing management for nephrotic syndrome adapts as the disease progresses, with strategies evolving to address advancing symptoms and complications.Early-Stage Management In the early stages, nursing interventions for nephrotic syndrome resemble those used in managing acute glomerulonephritis, focusing on symptom monitoring, fluid balance, and managing mild to moderate edema.Vital Signs: Regularly monitor blood pressure, pulse, respiratory rate, and temperature to promptly identify...

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living donor...
