Evaluation and therapeutic outcome of palpable purpura.
Palpable purpura is the clinical hallmark of leukocytoclastic vasculitis. Its etiology can be varied but often is elusive. Henoch- Schonlein purpura (HSP) is a distinct subtype of hypersensitivity vasculitis of unknown cause occurring primarily in children. IgA deposits in vessels is thought to be diagnostic of HSP. This study is aimed to evaluate the etiology, clinical manifestations and therapeutic outcome in patients with palpable purpura and to assess the relevance of IgA deposits in these patients. Thirty-six patients with palpable purpura were evaluated by history and laboratory investigations including biopsy for histopathology and direct immunofluorescence . Twenty-four patients received treatment with dapsone, steroids or a combination. All patients were followed up at first and third month and then at 6 monthly intervals for a maximum of 2 years.
