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.
Abstract:
We evaluated the prevalence and the types of infectious foci in oral as well as ear, nose, and throat diseases, and we examined incidence of renal involvement with active treatment for focal infection in children with Henoch-Schönlein Purpura. A total of 96 children who presented at Aichi Children's Health and Medical Center and were diagnosed as having HSP were evaluated for infectious foci in the ear, nose, throat, and oral cavities. Seventy-one of 96 children (74.0%) had some type of infectious lesion, such as sinusitis or tonsillitis, and the prevalence of sinusitis was the highest (51 cases, 53.7%). In 44 HSP patients without renal involvement at the first examination, the incidence of nephritis was lower (13.6%) than in previous reports (17-54%) due to our aggressive intervention for infectious foci.

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.
