Clinical trials of IL-3, IL-11 and thrombopoietin (TPO) against chemotherapy-induced thrombocytopenia were reviewed. Many clinical trials of IL-3 were conducted, which increased the platelet nadir counts and improved the recovery from thrombocytopenia at a dose of 5 micrograms/kg/day for 7 to 14 days. Major side effects, fever and headache, were tolerable. The combination with G-CSF was also examined. IL-11 improved the platelet nadir counts and the recovery from thrombocytopenia at a dose of 50 micrograms/kg/day for 14 days. Adverse events of IL-11 were general fatigue and edema, which were mild. Phase I/II studies of TPO were conducted, which showed a marked increase of platelet counts and improvement in recovery from thrombocytopenia. A few patients experienced mild thrombo-embolism. Improved QOL and survival benefits in the evaluation of these cytokines must be demonstrated.

Loading of the rat ulna is an ideal model to examine stress fracture healing. The aim of this study was to undertake a detailed examination of the histology, histomorphometry and gene expression of the healing and remodelling process initiated by fatigue loading of the rat ulna. Ulnae were harvested 1, 2, 4, 6, 8, and 10 weeks following creation of a stress fracture. Stress fracture healing involved direct remodelling that progressed along the fracture line as well as woven bone proliferation at the site of the fracture. Histomorphometry demonstrated rapid progression of basic multicellular units from 1 to 4 weeks with significant slowing down of healing by 10 weeks after loading. Quantitative PCR was performed at 4 hours, 24 hours, 4 days, 7 days, and 14 days after loading. Gene expression was compared to an unloaded control group. At 4 hours after fracture, there was a marked 220-fold increase (P<0.0001) in expression of IL-6. There were also prominent peak increases in mRNA expression for OPG, COX-2, and VEGF (all P<0.0001). At 24 hours, there was a peak increase in mRNA expression for IL-11 (73-fold increase, P<0.0001). At 4 days, there was a significant increase in mRNA expression for Bcl-2, COX-1, IGF-1, OPN, and SDF-1. At 7 days, there was significantly increased mRNA expression of RANKL and OPN. Prominent, upregulation of COX-2, VEGF, OPG, SDF-1, BMP-2, and SOST prior to peak expression of RANKL indicates the importance of these factors in mediating directed remodelling of the fracture line. Dramatic, early upregulation of IL-6 and IL-11 demonstrate their central role in initiating signalling events for remodelling and stress fracture healing.
