Management of Henoch-Scholein Purpura (HSP) in Children
Introduction
Henoch-Schonlein purpura (HSP) is a multisystem disorder affecting mainly the skin, joints, gastro-intestinal tract and kidneys. Involvement of other organs (pulmonary haemorrage and CNS involvement) is rare. The extrarenal manifestations are due to a small vessel leukocytoclastic vasculitis. In the kidneys there is mesangial expansion with deposition of IgA. HSP can occur at any age but is most frequent in children under 10 years. There is a slight male predominance. The incidence is reported as 13.5-21.7/100,000 per year. It is more common in winter and commonly follows an upper respiratory infection. The aetiology and pathogenesis are poorly understood.

|
Cutaneous

Gastrointestinal
Articular
Renal
Other features
- Occurs in 2/3 of cases (90% of those with renal involvement)
- Abdominal pain may preceed rash in 14-36% of patients
- Vomiting, diarrhoea, periumbilical pain, bloody stools, upper GIT haemorrhage
- Intussusception in 5% of patients
- Rarely: Haemorrhagic pancreatitis, hydrops of the gall bladder, pseudomembranous colitis
Articular
- 50-80% of patients
- Arthralgia, periarticular oedema
- Synovial effusions are typically absent
- Knees and ankles most commonly affected, less commonly wrists, fingers and elbows
Renal
- Present in 40-60%
- Renal involvement is often absent at presentation and may only be apparent weeks or months later
- Presentation of renal involvement is variable:
- Microscopic haematuria - transient or persistent
- Macroscopic haematuria
- Proteinuria
- Nephrotic syndrome
- Mixed nephritic-nephrotic syndrome
Other features
- Genital - Orchitis, cord haematoma, testicular pain or necrosis, painful ecchymotic induration of the scrotum
- CNS - Seizures, encephalopathy, coma, Guillian-Barre, cortical blindness, intracerebral haemorrhages, stroke
- Carditis
- Parotitis
- Pulmonary disease with heamorrhage
Differential Diagnosis
- Sepsis, especially meningococcal disease (see guideline for meningococcal disease)
- Systemic vasculitides (Wegeners, SLE, hypersentivity vasculitis, polyarteritis nodosa)
- ITP and other forms of purpura (see ITP guideline)
Initial Investigations
Other investigations are not routine if the patients is well, the clinical diagnosis is confident and the urine dipsticks are clear.
- Blood Pressure
- Urine Dipstick
- FBC, U&E, Clotting
Other investigations are not routine if the patients is well, the clinical diagnosis is confident and the urine dipsticks are clear.
Initial Management
- Supportive - Hydration, nutrition, electrolyte balance
- Simple analgesia - use non-steroidal anti-inflammatory agents only if the renal function is normal.
- If severe abdominal pain, arthritis, pulmonary haemorrhage - consider oral prednisolone 1-2mg/kg [1], [2] after discussion with consultant
- If severe skin manifestations - consider oral colchicine or oral dapsone [3], [4] in consultation with dermatologist

- IV methylprednisolone 600mg/m2 once daily for 3 doses [18], [22]
- Plasma exchange [23]
- Cyclophosphamide PO (2.5mg/kg OD for 8 weeks) [18]
- (After 3 days of methylprednisolone) Prednisolone PO60mg/m2 once daily for 1 month, 40mg/m2 once daily for 1 month, then taper over the next 4 months (total 6 months)
- >50% Crescents
- IV Methylprednisolone 600 mg/m2 once daily for 3 doses [19], [22]
- Cyclophosphamide PO (2.5mg/kg once daily, 8wks) [18]
- (After 3 days of methylprednisolone) prednisolone PO 60mg/m2 once daily for 1 month, 40mg/m2 once daily for 1 month, then taper over next 4 month: total 6 months
- +/- Plasma exchange
- Crescents [18], [19], [20], [21], / Tubulo-interstitial changes [18], [19], [6]
- IV Methylprednisolone 600 mg/m2 once daily for 3 doses [19], [22], [26]
- +/- cyclophosphamide [22], [24], [25]
- (After 3 days of methylprednisolone) prednisolone PO 60mg/m2 once daily for 1 month, 40mg/m2 once daily for 1 month, then taper over next 4 months: total 6 months
