AIMS: To elucidate bone mineral density (BMD) and bone turnover in an un-selected group of patients with Systemic Sclerosis (SSc) in national based registry. MATERIAL AND METHODS: All patients who have been diagnosed with SSc in Iceland were invited to participate in the study. Participants underwent standardized interview and delivered urine and blood samples for measurements of various bone metabolites (e.g. PTH, osteocalcin, Cross Laps, PINP, IGF-1, Cystatin-C and 25-OH-vitamin-D), before they underwent measurement of BMD with DEXA (QDR 4500 Elite). RESULTS: Twenty-four individuals, 20 female and four male, of 29 diagnosed patients with SSc in Iceland accepted to participate in the study (83%). The mean age was 60 +/- 15 years. Seventeen of 20 females were postmenopausal. Twelve patients had history of fractures. Only four patients were on treatment with bisphosphonate. All measured bone metabolites were in normal ranges, but U-calcium was in the lower ranges. According to DEXA, eight patients had osteopenia (T-value = -1.0 - -2.5) and three osteoporosis (T-value
