Rheumatic Diseases

Rheumatic diseases comprise a broad spectrum of disorders that affect the joints, muscles, bones, and connective tissues. While many people associate these conditions with the elderly, they can affect individuals of all ages. The complexities of rheumatic diseases often lead to misdiagnosis or delayed treatment, underscoring the importance of increased awareness and education.

What are Rheumatic Diseases?

Rheumatic diseases are autoimmune and inflammatory diseases that cause the immune system to attack joints, muscles, bones, and organs. Unlike localized injuries, rheumatic diseases can involve multiple areas of the body simultaneously, leading to chronic pain and disability.

Connective Tissue Disorders

Connective tissue diseases are a subset of rheumatic diseases characterized by inflammation and degeneration of connective tissues. These tissues include cartilage, bone, and fat, which serve as a framework and support system for the body. Common connective tissue diseases include lupus, scleroderma, and rheumatoid arthritis. If not diagnosed and managed promptly, these conditions can lead to severe complications.

Causes and Pathophysiology

Rheumatic heart disease begins with a Group A streptococcal throat infection. If not treated effectively, the infection can lead to rheumatic fever, an inflammatory condition that affects the heart, joints, skin, and brain. Over time, rheumatic fever can cause permanent damage to the heart valves, resulting in rheumatic heart disease.

The pathophysiology of RHD involves an autoimmune reaction in which the body’s immune response attacks its tissues, mistaking them for streptococcal bacteria. The inflammation primarily affects the heart valves, causing them to become scarred and narrowed, a condition known as stenosis, or leaky, a condition known as regurgitation.

Symptoms and Diagnosis

Rheumatic heart disease symptoms can vary depending on the severity of valve damage. Common symptoms include shortness of breath, chest pain, fatigue, and palpitations. In severe cases, individuals may experience heart failure, stroke, or endocarditis.

Diagnosing rheumatic heart disease involves a combination of medical history, physical examination, and diagnostic tests such as echocardiograms, electrocardiograms (ECGs), and blood tests to detect inflammation and heart damage.

Complications and Treatment

Rheumatic heart disease can lead to severe complications if left untreated. Some of the common complications include heart failure, atrial fibrillation, and stroke. These complications arise due to the impaired function of the heart valves, which disrupts normal blood flow and increases the workload on the heart.

Treatment Options

The treatment of rheumatic heart disease focuses on managing symptoms, preventing further heart damage, and addressing complications. Medications such as diuretics, beta-blockers, and anticoagulants can help manage symptoms and reduce the risk of complications. In advanced cases, surgical interventions like valve repair or replacement may be necessary.

Prevention Strategies

Preventing rheumatic heart disease involves early treatment of streptococcal throat infections with antibiotics to prevent the progression of rheumatic fever. Public health initiatives aimed at improving access to healthcare and education about the importance of treating sore throats can significantly reduce the incidence of RHD.
