A single 1 g/kg dose of intravenous immunoglobulin is a safe and effective treatment for immune thrombocytopenia; results of the first HaemSTAR "Flash-Mob" retrospective study incorporating 961 patients Of particular note, whether patients were dosed with 1 g/kg on 1 or 2 consecutive days, did not affect the attainment of platelet counts of >=30 × 10 SP 9 sp /l or >=100 × 10 SP 9 sp /l or duration of time for which the platelet count was above these thresholds (Fig 1). (A) The probability of those with an initial platelet count <30 × 109/l attaining a platelet count over this threshold, (B) the probability of those with an initial platelet count of <100 × 109/l attaining a platelet count over this threshold, (C) the probability of those achieving a platelet count of >=30 × 109/l maintaining a platelet count over this threshold and (D) the probability of those achieving a platelet count of >=100 × 109/l maintaining a platelet count over this threshold.
