IntroductionRecombinant thrombomodulin (rTM), which degrades factors Va and VIIIa by activating protein C, has been developed as a new drug for treating disseminated intravascular coagulation (DIC).Materials and methodsSince July 2009, we have treated 25 children with DIC using rTM (380 U/kg/day, or 130 U/kg/day for newborns) as a first-line therapy. Median duration of rTM administration was 5 consecutive days (range, 2–13 days). We employed DIC criteria of the Japan Welfare and Health Ministry. The first day on which rTM treatment was given was defined as day 1.ResultsMedian patients age was 3 years. Underlying diseases were hematological disorders (n = 13) and severe infection (n = 12). Overall, 20 of the 25 patients had recovered from DIC by day 7 and 22 of the 25 patients remained alive at day 28. Median Pediatric Logistic Organ Dysfunction score improved from 11 on day 1 to 2 on day 7 (p = 0.009). Laboratory data (median) on day 7 (prothrombin time (PT) ratio, 1.15; fibrin and fibrinogen degradation products (FDP), 9.6 mg/l; D-dimer, 1.6 mg/l FEU; antithrombin, 112%; protein C, 105%) were significantly improved compared to results on day 1 (PT ratio, 1.39; FDP, 21.6 mg/l; D-dimer, 6.4 mg/l FEU; antithrombin, 86%; protein C, 54%). Whereas, 5 patients failed to respond and serious bleeding events were observed in 2 newborns.ConclusionThe efficacy of rTM cannot be assessed from the present dataset, due to several limitations such as the small heterogenous patient cohort, and the lack of age- and disease-matched controls. Nevertheless, this case-series remains important in terms of enabling further prospective control studies to evaluate the efficacy of rTM in children.
