Insights

This study documents 106 Takayasu arteritis (TA) patients, finding hypertension common. It also reveals protein kinase C (PKC) pathway activation in TA pathogenesis, suggesting a new therapeutic target.

Area of Science:

  • Cardiovascular Medicine
  • Immunology
  • Genetics

Background:

  • Takayasu arteritis (TA) is a rare, chronic inflammatory disease affecting large arteries, primarily the aorta and its branches.
  • Understanding the clinical spectrum and pathogenesis of TA is crucial for effective management.

Purpose of the Study:

  • To document the clinical features, disease classification, treatment modalities, and pathogenetic insights of Takayasu arteritis (TA) in a cohort of 106 patients.
  • To investigate the role of protein kinase C (PKC) and intracellular calcium signaling in TA pathogenesis.

Main Methods:

  • Retrospective analysis of clinical data from 106 TA patients over 16 years.
  • Classification of TA based on aortography findings (Types I-V).
  • Assessment of T cell signaling pathways, including protein kinase C (PKC), intracellular calcium, and inositol 1,4,5 triphosphate levels.

Main Results:

  • Hypertension was the most frequent presentation (51.3%), with 77.4% of patients diagnosed at presentation.
  • Type V TA (involving multiple aortic segments) was most common (55.7%).
  • Elevated protein kinase C (PKC) activity, intracellular calcium, and inositol 1,4,5 triphosphate were observed in T cells of TA patients, suggesting pathway activation.

Conclusions:

  • Takayasu arteritis (TA) presents with diverse clinical features, hypertension being predominant.
  • The study provides evidence for the activation of the PKC-calcium pathway in the pathogenesis of TA.
  • These findings may offer novel therapeutic targets for managing Takayasu arteritis.

Pericarditis I: Introduction

Pericarditis is defined as the inflammation of the pericardium, the thin, sac-like membrane surrounding the heart. This condition can cause significant chest pain and other symptoms, often necessitating medical intervention. The pericardium has two layers: the inner visceral layer and the outer parietal layer, separated by a small amount of fluid that reduces friction during heartbeats.Types of PericarditisPericarditis can be classified into several types based on the duration and nature of the...

Pericarditis III: Medical Management

The primary objectives of managing pericarditis are to determine the underlying cause, provide effective therapy for treatment and symptom relief, and promptly detect signs and symptoms of cardiac tamponade. The following outlines the essential aspects of medical management for pericarditis:ObjectivesDetermine the Cause: Identifying the underlying cause of pericarditis is crucial for targeted treatment. Causes include viral infections, autoimmune diseases, post-cardiac injury syndrome, and...

Rheumatic 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...

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...

Rheumatic 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...
