Glomerulonephritis in rheumatoid arthritis
British Journal of Rheumatology
|November 1, 1993
Summary
Rheumatoid arthritis patients can develop glomerulonephritis unrelated to specific therapies. This study details varied kidney disease presentations and histological findings in ten rheumatoid arthritis cases.
Area of Science:
- Nephrology
- Rheumatology
- Immunology
Background:
- Rheumatoid arthritis (RA) is a chronic autoimmune disease.
- Glomerulonephritis (GN) can be a complication of systemic autoimmune conditions.
- Previous associations of GN with gold or penicillamine therapy in RA patients are noted.
Purpose of the Study:
- To investigate glomerulonephritis in rheumatoid arthritis patients.
- To characterize the clinical and histological features of GN in RA.
- To determine if GN in RA is related to specific gold or penicillamine treatments.
Main Methods:
- Retrospective analysis of 10 rheumatoid arthritis patients with glomerulonephritis.
- Review of clinical presentations including nephrotic syndrome, proteinuria, and hematuria.
- Analysis of renal biopsy histology.
Main Results:
- Ten RA patients developed glomerulonephritis unrelated to gold or penicillamine therapy.
- Seven patients presented with nephrotic syndrome; three with proteinuria and hematuria.
- Histological findings included membranous nephropathy (5), IgA nephropathy (2), focal segmental necrotizing glomerulonephritis (2), and focal segmental glomerulosclerosis (1).
Conclusions:
- Glomerulonephritis can occur in rheumatoid arthritis patients independently of gold or penicillamine treatment.
- Diverse histological patterns of glomerulonephritis are observed in RA.
- Further research is needed to understand the pathogenesis of GN in RA.

01:23Rheumatic Heart Disease I: Introduction
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
01:21Rheumatic Heart Disease III: Medical Management
Rheumatic heart disease (RHD) management can be divided into two main strategies: prevention and long-term management.Primary PreventionPrimary prevention focuses on timely diagnosis and management of group A streptococcal pharyngitis to prevent acute rheumatic fever. The most widely used antibiotic for treating this condition is intramuscular benzathine penicillin G.Acute Rheumatic Fever TreatmentThe primary treatment goal for a patient diagnosed with acute rheumatic fever is to suppress the...
01:20Rheumatic Heart Disease IV: Nursing Management
AssessmentA comprehensive assessment is essential in managing a patient with rheumatic heart disease (RHD). Begin with obtaining a detailed medical history, including recent streptococcal infections, a history of rheumatic fever, or previously diagnosed rheumatic heart disease. Assess the patient for symptoms such as fever, chest pain, widespread joint pain (arthralgia), tachycardia, pericardial friction rub, muffled heart sounds, heart murmurs, peripheral edema, subcutaneous nodules, and...
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,...
01:27Streptococcal Pharyngitis
Streptococcal pharyngitis, commonly known as “strep throat,” is an acute infection of the oropharyngeal tissues caused by the Gram‑positive Group A Streptococcus (Streptococcus pyogenes). Transmission occurs primarily through respiratory droplets expelled during coughing, sneezing, or talking.Mechanisms of Host Entry and Immune EvasionUpon entering the host, S. pyogenes adheres to the mucosal epithelial cells of the pharynx via surface proteins, notably lipoteichoic acid and the antiphagocytic...
