Active clinical trials for "Calcinosis"

The aim of this study was to evaluate the efficacy of concentrated growth factor (CGF) in applied in the regenerative treatment of multiple adjacent papillary black triangles (MAPBT) occured as a result of soft tissue loss. Interdental papillary regeneration was evaluated with the change in the area of interproximal spaces calculated on each of the intraorally scanned images obtained with digital impressions of the interproximal space with irregular borders.This controlled, examiner-blinded, clinical study included of 40 patients with 120 open embrasures which resulted from papillary loss in adjacent teeth in the anterior maxillary esthetic zone resulting in black triangles (BTs). Then patients were randomly assigned to receive surgical regenerative periodontal treatment(test) or periodontal care(control)The test group was formed of 20 patients with 60 adjacent papillary defects . A control group was formed of 20 patients with 60 adjacent papillary defects.. A total of 480 images obtained with the digital impressions . Evaluations of the test group were made preoperatively and at 3, 6 and 12 months postoperatively. For the control group, oral hygiene instruction was provided. Control group is evaluated by the same procedure with test group but the surgical part is not performed. Lost interdental papillary area (PA)were calculated. In the test group, the percentage of papillary filling, the presence of keratinized gingiva, the thickness of papillary gingiva, blood thrombocyte count and mean platelet volume values(MPV) were recorded.

Vitamin K2 deficiency has been shown to be profound in hemodialysis patients. It is reflected by high plasma levels of dephosphorylated-undercarboxylated Matrix Gla protein (dp-ucMGP) and seems to be correlated with vascular calcifications. Vascular calcifications can be assessed using the AC24 score on a lateral abdominal X-ray. The aim of this study is to assess first the rate of decrease of dp-ucMGP in a hemodialysis cohort after supplementation with vitamin K2 and the correlation between this rate of decrease and the Aortic Calcification Severity (AC24) score. The factors associated with high levels of dp-ucMGP will be analyzed as well.

The present study will examine the treatment effect of sodium thiosulfate on coronary calcification in patients on hemodialysis.

Research proposal to evaluate the impact of different phosphate binders on the progression of cardiovascular calcification and QT dispersion in new haemodialysis patients.

The purpose of this study is to determine if supplemental vitamin K will reduce age-related bone loss in elderly men and women above that achieved by supplementation.

Alendronate is a safe and effective drug for treating osteoporosis in post-menopausal women. However, its safety and efficacy in increasing bone mineral density in chronic peritoneal dialysis (PD) patients have not been investigated. Etidronate, another bisphosphonate, can suppress the extent of coronary artery calcification in chronic hemodialysis patients. The hypothesis of this study is that alendronate can increase bone mineral density and suppress aortic and coronary artery calcification in chronic peritoneal dialysis patients.

OBJECTIVES: I. Determine whether intermittent, long-term, subcutaneous administration of calcitonin increases phosphaturia, reduces hyperphosphatemia, and increases intact parathyroid hormone levels in patients with tumoral calcinosis. II. Determine whether calcitonin reduces or prevents tumor recurrence. III. Determine whether hyperphosphatemia abolishes the normal circadian pattern of serum phosphorus. IV. Determine how repetitive calcitonin administration alters the biochemical markers of bone metabolism in osteopenic patients with tumoral calcinosis.

This is a French, prospective, single-arm, multi-center registry to confirm the safety and efficacy of the Diamondback 360 TM Orbital Atherectomy System in the preparation of de novo calcified coronary lesions before implantation of a coronary endoprothesis in adult subjects. The primary safety endpoint is 30-day MACE and the efficacy endpoint is procedural success.

The purpose of this study is to determine whether the combination of removal of the calcification in calcific tendinitis of the shoulder (supraspinatus and/or infraspinatus tendon) by aspiration with a needle and syringe (barbotage) and a corticosteroid injection is more effective than corticosteroid or sham injection alone.

The primary objective of the current study is to determine whether Ataciguat (HMR1766) slows progression of valve calcification in patients with moderate calcific aortic valve stenosis. Secondary and tertiary objectives are to determine whether Ataciguat slows progression of aortic valve function, reduces systemic inflammation, and prevents left ventricular dysfunction in patients with moderate calcific aortic valve stenosis.
