Renal lesions in acute rheumatic fever
Annals of Internal Medicine
|March 1, 1981
Summary
Acute rheumatic fever can present with varied kidney problems, including different types of glomerulonephritis and interstitial nephritis. These renal abnormalities associated with rheumatic fever are typically temporary, highlighting the importance of understanding diverse kidney manifestations.
Area of Science:
- Nephrology
- Rheumatology
- Pathology
Background:
- Acute rheumatic fever (ARF) is an inflammatory condition that can affect multiple organ systems.
- Renal involvement in ARF is not uncommon but can manifest in diverse ways.
- Percutaneous renal biopsy is a diagnostic tool for evaluating kidney abnormalities.
Observation:
- Four patients with ARF and renal function/urinary sediment abnormalities underwent renal biopsy.
- The study observed a range of distinct renal lesions in these patients.
- Clinical renal abnormalities were transient in all cases.
Findings:
- Focal glomerulonephritis was identified in one patient.
- Classic acute exudative poststreptococcal glomerulonephritis was observed.
- Mesangioproliferative glomerulonephritis was diagnosed in one case.
- Severe interstitial nephritis was found in another patient.
Implications:
- ARF can be associated with a wide spectrum of renal pathology.
- Recognizing the variability of renal lesions is crucial for accurate diagnosis and management of ARF.
- Transient nature of renal abnormalities suggests potential for recovery with appropriate treatment.

01:25Endocarditis II: Clinical Features of Infective Endocarditis
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...
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...
01:22Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies
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...
01:25Acute Inflammation III: Local and Systemic Effects
Acute inflammation produces a coordinated set of local and systemic changes that limit injury, eliminate pathogens, and initiate repair. These responses arise within minutes of infection, trauma, or chemical insult and are driven by vascular alterations and leukocyte-derived mediators. When the stimulus resolves, the reaction typically abates within days.Local EffectsAt the site of injury, arteriolar vasodilation increases blood flow, resulting in redness and warmth. Simultaneously, increased...
