Insights

Vaccination completeness is low in Swiss children with pediatric inflammatory rheumatic diseases (PRD), especially for PRD-specific vaccines. Early intervention and collaboration are crucial to improve immunization rates in this vulnerable group.

Area of Science:

  • Pediatric Rheumatology
  • Infectious Diseases
  • Immunology

Background:

  • Children with pediatric inflammatory rheumatic diseases (PRD) face an elevated risk of infections.
  • Vaccinations are critical for preventing vaccine-preventable diseases in this population.

Purpose of the Study:

  • To evaluate vaccination completeness in Swiss PRD patients.
  • To stratify vaccination status based on immunosuppressive treatment (IST).

Main Methods:

  • A multicenter observational cohort study involving PRD patients under 18 years old.
  • Assessment of overall vaccination status, including the Swiss national immunization program (NIP) and PRD-specific vaccines.
  • Stratification of completeness by IST and disease course.

Main Results:

  • Overall vaccination completeness was low at 3.8%.
  • Completeness for NIP vaccinations was 70.1%, while PRD-specific vaccination completeness was only 3.8%.
  • Vaccination rates for pneumococcal, hepatitis B, and HPV were 50.4%, 20%, and 37.9%, respectively.

Conclusions:

  • A significant gap exists in overall and PRD-specific vaccination completeness among children with PRD.
  • Incomplete vaccination status often persists if not addressed early in the disease course.
  • Enhanced collaboration between pediatricians and rheumatologists, standardized assessments, and timely reminders are vital to improve vaccination coverage.

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 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 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...

Development of Immunocompetence

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

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...
