Insights

Infectious foci like sinusitis are common in children with Henoch-Schönlein Purpura (HSP). Aggressive treatment of these infections reduced the incidence of nephritis in HSP patients.

Area of Science:

  • Pediatrics
  • Nephrology
  • Infectious Diseases

Background:

  • Henoch-Schönlein Purpura (HSP) is a common vasculitis in children.
  • Infectious foci, particularly in the upper respiratory tract and oral cavity, are suspected triggers for HSP.
  • Renal involvement (nephritis) is a significant complication of HSP.

Purpose of the Study:

  • To determine the prevalence and types of infectious foci in children diagnosed with HSP.
  • To investigate the incidence of renal involvement in HSP patients undergoing active treatment for identified infectious foci.
  • To assess if early intervention for infectious foci impacts the development of nephritis in HSP.

Main Methods:

  • A retrospective study of 96 children diagnosed with HSP at Aichi Children's Health and Medical Center.
  • Evaluation for infectious foci in the ear, nose, throat, and oral cavities.
  • Monitoring of renal involvement (nephritis) in patients, particularly those treated for infectious foci.

Main Results:

  • A high prevalence of infectious foci was observed in 74.0% of the 96 HSP patients.
  • Sinusitis was the most common infectious focus, present in 53.7% of cases.
  • In 44 HSP patients without initial renal involvement, aggressive treatment of infectious foci was associated with a lower incidence of nephritis (13.6%) compared to historical data.

Conclusions:

  • Infectious foci are highly prevalent in children with Henoch-Schönlein Purpura.
  • Early and aggressive intervention for infectious foci may reduce the risk of developing nephritis in HSP patients.
  • Targeting infections in the ear, nose, throat, and oral cavities is a crucial aspect of managing HSP in children.

Peptic Ulcer Disease I: Introduction

Peptic Ulcer Disease (PUD) is characterized by mucosal excavation in the esophagus, stomach, pylorus, or duodenum. It can manifest as acute or chronic based on the extent and duration of mucosal involvement.
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
Peptic ulcers can also be...

Tonsillitis I: Introduction

Tonsillitis is inflammation of the tonsils, which are two lymphoid tissue masses at the back of the throat. This condition can cause discomfort and irritation in the throat.
Etiology

Asthma I: Introduction01:28

Asthma I: Introduction

Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...

Streptococcal Pharyngitis

Streptococcal pharyngitis, commonly known as “strep throat,” is an acute infection of the oropharyngeal tissues caused by the Gram‑positive Group A Streptococcus (Streptococcus pyogenes). Transmission occurs primarily through respiratory droplets expelled during coughing, sneezing, or talking.Mechanisms of Host Entry and Immune EvasionUpon entering the host, S. pyogenes adheres to the mucosal epithelial cells of the pharynx via surface proteins, notably lipoteichoic acid and the antiphagocytic...
Peptic Ulcer01:27

Peptic Ulcer

Peptic ulcers are erosive lesions of the gastric or duodenal lining, most commonly caused by Helicobacter pylori infection. This Gram-negative, helical bacterium has adapted to survive the stomach’s acidic environment by producing urease, which converts urea into ammonia and carbon dioxide. The ammonia neutralizes gastric acid in the bacterium’s immediate environment, allowing colonization of the gastric mucosa. H. pylori attaches to mucus-secreting epithelial cells, penetrates the mucus...

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...
