Factor XIII subunit A (FXIII A) is synthesized by megakaryocytes, and monocytes/macrophages. In addition, the liver has been reported as an extrahaematopoietic source of FXIII A. At present, the extent of contribution of either haematopoietic or extrahaematopoietic sources to the plasma FXIII A level is unknown. We studied the effect of bone marrow aplasia due to high-dose chemotherapy followed by autologous peripheral blood stem cell transplantation (ASCT) on plasma FXIII A activity and concentration in 20 patients with haematological or solid tumour malignancies. A multiple linear regression model was used to assess the effect of gender, age, malignancy and treatment types, platelet and monocyte counts, abnormal liver function tests, prothrombin time, and number of platelet transfusions on FXIII activity measured in plasma before and following ASCT. Significant correlation between platelet counts and FXIII A activity in plasma was observed (r = 0.51, P = 0.0001), which remained after the adjustment for the aforementioned parameters (multiple R = 0.52, P = 0.0001). In contrast, no significant correlation between FXIII A levels and monocyte counts was observed (r = 0.19), and this lack of correlation persisted after the adjustment. These results suggest that in the ASCT model, following myeloablation, platelets but not monocytes are the haematopoietic cells that contribute significantly to plasma FXIII A levels. In addition, extra-haematopoietic sources of FXIII synthesis may also contribute to FXIII levels in plasma.
