We have investigated the effect of HGF in vivo and in vitro in MDS using a recently developed FCM assay involving the simultaneous measurement of cell surface antigens, DNA content, and BrdUrd or IodUrd incorporation. This allows for the determination of the dynamic cell kinetic parameters: LI, T(s), and T(pot) and we observed that in vitro HGF stimulation resulted in a significant decrease in mean T(pot) values from 6.6 to 3.5 days. Importantly, we demonstrated that in vivo GM-CSF administration to patients with RAEB resulted in a shortening of T(pot) within the 2 first weeks of GM-CSF treatment.

Immunosuppressive therapy is the treatment for aplastic anemia patients ineligible for transplantation. The role of hematopoietic growth factors as adjunct to treatment in these patients is unclear. We conducted a systematic review and meta-analysis of randomized controlled trials comparing treatment with immunosuppressive therapy and hematopoietic growth factors to immunosuppressive therapy alone in patients with aplastic anemia. Two reviewers appraised the quality of trials and extracted data. For each trial, results were expressed as relative risks with 95% confidence intervals (CI) for dichotomous data. The addition of hematopoietic growth factors yielded no difference in overall mortality at 100 days, one year and five years [relative risks 1.33 (95% CI 0.56-3.18), relative risks 0.90 (95% CI 0.50-1.63) and relative risks 0.89 (95% CI 0.55-1.46), respectively]. There was no difference in overall hematologic response and in the occurrence of infections. HGF significantly decreased the risk for relapse, relative risks 0.45 (95% CI 0.30-0.68, 3 trials). Hematopoietic growth factors were not associated with higher occurrence of myelodysplastic syndrome and acute myeloid leukemia or paroxysmal nocturnal hemoglobinuria. The addition of hematopoietic growth factors does not affect mortality, response rate or infections occurrence. Therefore, it should not be recommended routinely as an adjunct to the immunosuppressive therapy for patients with aplastic anemia.
