NCT00871962
The purpose of this prospective cohort study is to determine factors involved in survival in new COPD patients treated by long-term oxygen therapy. Background: long-term oxygen therapy is indicated in patients with severe COPD. No studies have been performed in the past 20-25 years to examine the results of early clinical trials. Further studies are necessary to understand the utility of oxygen therapy in severe COPD.
NCT01423071
The purpose of this study is to determine the prevalence of pulmonary hypertension (PH) among patients suffering from Chronic Obstructive Pulmonary Disease (COPD) and to assess the quality of life in those patients with concomitant PH compared to COPD patients without PH and those only suffering from pulmonary arterial hypertension (PAH) respectively.
NCT02213276
Diabetes is associated with an increased risk of bone fractures, but current predictors of bone fracture seem to underestimate this risk. It is commonly known that increased levels of certain biochemical bone markers predict low-energy fractures, but the pattern of these markers in diabetics still show heterogeneity and inconsistency. Part of the pathology of diabetes is a high blood glucose level, and this can potentially influence bone turnover and thereby bone markers. Chronic inflammation in patients with inflammatory bowel disease is shown to increase bone resorption, and the same may be the case in diabetics. The purpose of this project is to investigate whether glucose has a direct effect on bone markers or an indirect effect through intestinal hormones or inflammatory processes.
