This study compared the efficacy and safety of high-dose dexamethasone (HD-DXM)
and conventional prednisone (PDN) on the largest cohort to date as first-line
strategies for newly diagnosed adult primary immune thrombocytopenia (ITP).
Patients enrolled were randomized to receive dexamethasone 40 mg/d for four days
(n = 95, non-responders received an additional four-day course of dexamethasone),
or prednisone 1.0 mg/kg daily for four weeks and then tapered (n = 97). One or
two courses of HD-DXM resulted in a higher incidence of overall initial response
(82.1% vs. 67.4%, P = 0.044) and complete response (50.5% vs. 26.8%, P = 0.001)
compared to prednisone. Time to response was shorter in the HD-DXM arm (P <
0.001), and a baseline bleeding score ≥ 8 was associated with a decreased
likelihood of initial response. Sustained response was achieved by 40.0% of
patients in the HD-DXM arm and 41.2% in the PDN arm (P = 0.884). Initial complete
response was a positive indicator of sustained response, whereas presence of
anti-platelet autoantibodies was a negative indicator. High-dose dexamethasone
was generally tolerated better. We concluded that high-dose dexamethasone could
be a preferred corticosteroid strategy for first-line management of adult primary
ITP. This study is registered at as NCT01356511.
