Design outcomes

Primary

MeasureTime frame
Main Objective: Patients who are treated with intravenous bisphosphonates frequently report a mild flu like illness after the first dosing (the acute phase reaction). We wish to determine whether this reaction is related to the activity of one particular type of white blood cell.;Secondary Objective: We wish to assess the quality of life of our patients using the EQ5D questionaire;Primary end point(s): Is there a change in activity and numbers of circulating gamma delta T cells when patients receive intravenous bisphosphonate and does this correlate with the patient experiencing an acute phase reaction.
