Insights
Age, sex, gastrointestinal issues, and high platelet counts are key indicators for kidney problems in Henoch-Schönlein purpura (HSP) patients. Early identification of these risk factors aids in predicting and managing renal involvement in children with HSP.
Area of Science:
- Pediatric Nephrology
- Rheumatology
- Clinical Immunology
Background:
- Henoch-Schönlein purpura (HSP) is a common vasculitis in children.
- Renal involvement is a significant complication of HSP, affecting up to 26.1% of patients.
- Identifying risk factors for renal involvement is crucial for timely management.
Purpose of the Study:
- To identify clinical and laboratory risk factors for renal involvement in pediatric HSP patients.
- To determine the relationship between platelet counts and renal involvement in HSP.
- To assess the predictive value of platelet count for renal complications.
Main Methods:
- Retrospective review of medical records for 107 children diagnosed with HSP.
- Evaluation of clinical and laboratory parameters, including platelet counts.
- Comparison of parameters between patients with and without renal involvement using multivariate logistic regression analysis.
Main Results:
- The mean platelet count was significantly higher in patients with renal involvement (P = 0.001).
- Age, sex, gastrointestinal involvement, and platelet count were identified as significant risk factors for renal involvement (P < 0.05).
- Platelet count demonstrated predictive value for renal involvement (AUC = 0.66, P = 0.009).
Conclusions:
- Age, sex, gastrointestinal involvement, and platelet count are significant risk factors for renal involvement in HSP.
- Elevated platelet counts may indicate an increased risk of kidney complications in children with HSP.
- These factors can aid in the early detection and management of renal complications in HSP.
Background:
The aim of this study is to identify the clinical and laboratory risk factors for renal involvement and to determine the relationship between platelet counts and renal involvement in (Henoch-Schönlein purpura) HSP patients.
Methods:
We reviewed the medical records of 107 children with HSP according to Eular/Press diagnostic criteria. Clinical and laboratory parameters for renal involvement were evaluated and compared to no renal involvement.
Results:
A retrospective study consisted of 107 children, 61 boys (57%), and 46 girls (43%). Twenty-eight of the 107 patients (26.1%) had renal involvement. The mean platelet count was significantly higher in patients with renal involvement when compared to patients without renal involvement (P = 0.001). The multivariate logistic regression analysis identified that age (P = 0.022), sex (P = 0.037), gastrointestinal involvement (P = 0.019), and platelet count (P = 0.019) were significantly associated with the renal involvement of HSP. The platelet count was predictive of renal involvement, which had odds ratio of 1.0, and achieved area under the curve of 0.66 for predicting the renal involvement within the acute stage of HSP (P = 0.009).
Conclusion:
Our study indicated that age, sex, gastrointestinal involvement, and platelet count were significant risk factors of renal involvement of HSP.

Factors Affecting Renal Clearance: Renal Impairment
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...
