Multicentre Longitudinal Study of Bone Mineralisation Characteristics in Marfan Syndrome and Ehlers-Danlos Syndrome

The general objective of this research is to evaluate the characteristics of bone mineralisation in patients with Marfan syndrome or Ehlers-Danlos syndrome on a large case series. In particular we intend to obtain data regarding the characteristics of bone mineralisation, as well as their variation over time and the relationships existing with other clinical-anamnestic parameters, in patients with Marfan syndrome or Ehlers-Danlos syndrome by retrospectively analysing (data already collected for normal clinical practice and already available at the hospital) the case history of the Cardiovascular genetic center at IRCCS Policlinico San Donato and the related Computerized Bone Mineralometry (MOC) examinations performed at the Radiology Service of the same hospital between 1 September 2019 and 31 December 2022.

Effect of Local Pamidronate in Preventing Bone Loss After Total Hip Arthroplasty

The aims of the study are to determine whether pamidronate applied locally causes diminished periprosthetic bone loss and decreased rate of bone turnover compared to patients receiving placebo after cemented total hip arthroplasty (THA). The study design will be prospective, randomized, and blind. Periprosthetic bone mineral density (BMD) will be measured with dual energy X-ray absorptiometry (DXA) at the total periprosthetic area as well as at seven Gruen zones or regions of interest. DXA scans will be performed at one week (baseline), three months, and six months postoperatively. Mean values of biochemical markers of bone turnover, BMD, and baseline-normalized BMD values will be compared between the bisphosphonate and placebo groups at each time point. For all temporal measurements including bone markers, BMD and normalized BMD, mean values will be compared across each time point within a given group.
