Insights
Obesity in children with Henoch-Schonlein purpura (HSP) is linked to more severe disease, including persistent rash and kidney problems. Obese children require longer treatments and more immunosuppressants.
Area of Science:
- Pediatrics
- Nephrology
- Immunology
Background:
- Henoch-Schonlein purpura (HSP) is a common vasculitis in children.
- The impact of obesity on HSP clinical course and treatment response requires further investigation.
Purpose of the Study:
- To evaluate the role of obesity in the clinical presentation and treatment outcomes of pediatric Henoch-Schonlein purpura.
Main Methods:
- Retrospective review of pediatric HSP cases (2000-2018) at a tertiary hospital.
- Comparison of demographic, clinical, and laboratory parameters between obese and non-obese HSP patients.
- Defined persistent purpura, mild/severe nephropathy based on established criteria.
Main Results:
- Obese HSP patients (17.6%) exhibited higher rates of persistent purpura, severe renal involvement, and hypertension.
- Obesity correlated with more severe renal histopathology and elevated erythrocyte sedimentation rate.
- Obese children experienced delayed symptom resolution and required longer steroid and immunosuppressive therapy.
Conclusions:
- Obesity is associated with a more severe clinical course and poorer treatment response in pediatric HSP.
- Findings suggest adipose tissue may influence inflammation in HSP, exacerbating disease severity and prolonging recovery.
- Obesity necessitates tailored management strategies for children with Henoch-Schonlein purpura.
Background:
We aimed to evaluate the role of obesity on the clinical course and response to treatment in patients with Henoch-Schonlein purpura (HSP).
Methods:
Data charts of children with HSP followed in a tertiary hospital between 2000 and 2018 were reviewed retrospectively. Persistent purpura was defined as skin involvement persisting for ≥ 30 days. Mild nephropathy was defined as the presence of microscopical hematuria and/or non-nephrotic proteinuria, while severe nephropathy as nephrotic proteinuria, nephritic syndrome, and/or kidney insufficiency. Obese and non-obese patients were compared for demographic, clinical, and laboratory parameters.
Results:
There were 199 patients (M/F, 104/95; median (IQR) presenting age 7.1 (5.0-9.2) years; follow-up period 17.5 (6-50) months). Obese patients (n = 35 (17.6%)) had significantly higher rate of persistent purpura (46% vs 21%), severe renal involvement (58% vs 31%), high-grade renal histopathological lesions (83% vs 39%), hypertension (29% vs 9%), and increased erythrocyte sedimentation rate (79% vs 56%). Obese patients also showed delayed improvement of cutaneous (25 vs 14 days), articular (12.5 vs 10.0 days), and kidney (280 vs 57 days) symptoms. Obese children used steroids for significantly longer period of time (236 vs 40 days). Furthermore, need for immunosuppressive medications were higher in obese patients (40% vs 9%).
Conclusions:
Obese children with HSP had higher erythrocyte sedimentation rate, hypertension, and severe renal involvement; showed delayed improvement of skin, joint, and kidney findings; and need more immunosuppressive medications and a longer period of steroid treatment. These findings may be associated with the effect of adipose tissue on inflammation.
