Insights

Women with rheumatic diseases (RD) had a low incidence of autoimmune diseases (AD) and neurodevelopmental disorders (ND) in their children. These findings suggest that reproductive concerns may not deter women with RD from having children.

Area of Science:

  • Rheumatology
  • Reproductive Medicine
  • Pediatrics
  • Genetics

Background:

  • Women with rheumatic diseases (RD) often face reproductive concerns, potentially leading to reduced family size.
  • Previous studies indicate an increased risk of autoimmune diseases (AD) and neurodevelopmental disorders (ND) in offspring of mothers with RD.

Purpose of the Study:

  • To investigate the long-term health outcomes of children born to women diagnosed with rheumatic diseases (RD) during their childbearing years.
  • To provide data for counseling women with RD regarding reproductive risks and offspring health.

Main Methods:

  • A nationwide survey of 398 women diagnosed with RD before age 45.
  • Data collected from 230 women with children, detailing offspring health outcomes.
  • Analysis of diagnoses in 299 children, including autoimmune diseases (AD) and neurodevelopmental disorders (ND).

Main Results:

  • Twelve children (4.0%) were diagnosed with AD, primarily in offspring of mothers with connective tissue diseases (CTD).
  • Eleven children (3.6%) had a certified diagnosis of ND, with a majority born to mothers with CTD.
  • No significant association was found between ND and prenatal exposure to maternal autoantibodies or anti-rheumatic drugs.

Conclusions:

  • The absolute numbers of offspring affected by AD and ND were low in this cohort of Italian women with RD.
  • The findings suggest that the health outcomes of offspring may not be a significant deterrent for women with RD considering childbearing.
  • This data can aid in reproductive counseling for women with rheumatic diseases.

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...

Autoimmune Disorders01:29

Autoimmune Disorders

Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

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...

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

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...
