Rheumatic 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...

COPD: Pathogenesis and Clinical Features

Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Summary
This summary is machine-generated.

Late-onset sarcoidosis (diagnosed over age 65) presents differently than in younger patients, with more asthenia, uveitis, and skin lesions. While outcomes are similar, elderly patients experience more corticosteroid side effects.

Area of Science:

  • Pulmonology
  • Rheumatology
  • Dermatology
  • Ophthalmology

Background:

  • Sarcoidosis is a multisystem inflammatory disease of unknown etiology.
  • While sarcoidosis can affect any age group, studies on elderly patients are limited.
  • Late-onset sarcoidosis, defined as diagnosis at age 65 or older, warrants specific investigation.

Purpose of the Study:

  • To analyze the clinical characteristics and outcomes of late-onset sarcoidosis.
  • To compare elderly patients with sarcoidosis to a younger cohort.
  • To identify diagnostic and therapeutic specificities in older individuals.

Main Methods:

  • Retrospective analysis of 30 patients with late-onset sarcoidosis (age ≥ 65) and 70 younger patients.
  • Comparison of clinical features, laboratory data, disease severity, and treatment.
  • Evaluation of outcomes including survival rates and adverse events over a mean 50-month follow-up.

Main Results:

  • Late-onset sarcoidosis showed a higher female-to-male ratio (5:1 vs. 1:1).
  • Elderly patients more frequently presented with asthenia (30% vs. 10%), uveitis (33.3% vs. 8.6%), and specific skin lesions (36.7% vs. 15.7%).
  • Asymptomatic chest abnormalities and erythema nodosum were absent in the elderly group; minor salivary gland biopsies were more diagnostic.

Conclusions:

  • Late-onset sarcoidosis exhibits distinct clinical and diagnostic features compared to younger-onset disease.
  • Minor salivary gland biopsy is a valuable diagnostic tool for elderly patients.
  • While overall outcomes and treatment approaches are similar, elderly patients face a higher risk of corticosteroid-related adverse events.
