Active clinical trials for "Sarcopenia"

In this study investigator's aim to determine the impact of insulin therapy on hypotension and sarcopenia

Sarcopenia is a loss of muscle mass and function that develops during aging. But sarcopenia is also observed in several other conditions: chronic diseases, cancers, viral infections, renal / respiratory insufficiency, immobility, obesity with low physical activity. This sarcopenia is named secondary sarcopenia to distinguish it from the age-associated primary sarcopenia. During prolonged hospitalizations in intensive care, a significant loss of muscular mass and function is also observed. This acute sarcopenia or Intensive Care Unit-Acquired Weakness (ICU-AW) may persist for several months after discharge from hospital. In addition to the loss of autonomy, the reduction of muscle mass has important metabolic implications, ranging from insulin resistance to modification of myokines production. Sarcopenia greatly increases the morbidity and mortality of patients regardless of its cause. The aim of our project is to identify the molecular mechanisms implicated in sarcopenia from different origin. We will particularly focus our work on the metabolic properties, the proliferation/ differentiation and regeneration capacities of the satellite cells (adult muscle stem cells). These satellite cells will be purified from quadriceps biopsies of human volunteers recruited at CHU Montpellier. These satellite cells will also be used to test the ability of some wild aromatic plants from south of France to improve cell survival and differentiation. This will allow us to identify the molecular mechanisms involved in sarcopenia development and identify potential therapeutic molecules.

Elderly patients generally have a tendency for having sarcopenia which refers to muscle loss that may be related to many factors. These patients also have a tendency to falls and injuries. Whether elderly sarcopenic patients have abrupt blood pressure drops upon standing remains unknown. Therefore, in this study, we sought to determine the incidence of orthostatic hypotension in sarcopenic elderly patients and compare it with elderly patients with no sarcopenia.

Sarcopenia on lumbar paraspinal muscles is receiving renewed attention as a cause of spinal degeneration. However, there are few studies on the precise concept and diagnostic criteria for spinal sarcopenia. Here, we develop the concept of spinal sarcopenia in community-dwelling healthy elderly people. In addition, we aim to observe the natural aging course of paraspinal muscle and back muscle strength, and investigate the association between conventional sarcopenic indices and spinal sarcopenia. This is a prospective observational cohort study with 120 healthy community-dwelling elderly people for 4 years. All subjects will be recruited according to no sarcopenia, possible sarcopenia, sarcopenia, and severe sarcopenia groups. The primary outcomes of this study are isokinetic back muscle strength and lumbar paraspinal muscle quantity and quality using lumbar spine MRI. Conventional sarcopenic indices and spine specific outcomes such as spinal sagittal balance, back performance scale, and Sorenson test will be also assessed. The data will be analysed using the intention-to-treat principle.

Sarcopenia is the loss of muscle mass and function with age. It has been recognised as an important health problem because it is common in older adults and associated with decline in physical function as well as a reduced quality of life. Sarcopenia can also lead to serious health consequences in terms of increased disability and the need for increased health and social care. There is considerable interest in understanding what causes sarcopenia in order to develop new approaches to prevention, diagnosis and treatment. To gain a detailed understanding of sarcopenia across a range of ages, we have designed the Muscle Ageing Sarcopenia Study (MASS_Lifecourse) in collaboration with members of the public and patients.

Prospective, observational study to assess sarcopenia across three chronic inflammatory diseases: chronic liver disease, Inflammatory Bowel Disease, Rheumatoid Arthritis both before and after therapeutic intervention (standard of care treatment i.e. nutrition/exercise; biologic for IBD etc).

Many systems such as the cardiovascular, pulmonary, musculoskeletal, hematological, immunological, gastrointestinal, central nervous system are affected due to decreased kidney function. The aim of this study was to investigate the relationship between physical performance and sarcopenia, peripheral muscle strength, activities of daily living, cognitive functions, physical activity level, fragility, pain in hemodialysis patients.

There is a lot of discussion concerning the normal cut-off points of skeletal mass among different populations worldwide. Genetic and environmental differences most probably lead to different measurements. Defining muscle mass in healthy young adults in Greece will provide information that can be used to determine normal ranges of muscle mass of both sexes and consequently define sarcopenia. The aim of the study is to define appendicular skeletal muscle mass reference measurements in healthy young adults in Greece. These values can be used to determine sarcopenia cut-offs according to recommendations.

Malnutrition is a common figure associated with liver cirrhosis. The main component of malnutrition in liver cirrhosis is represented by sarcopenia, a condition of a progressive and generalized loss of muscle mass and strength. Many studies have reported that sarcopenia is an independent predictor of morbidity and mortality in cirrhotic patients. Moreover, cirrhotic patients may develop simultaneous loss of skeletal muscle and gain of adipose tissue, culminating in a condition of "sarcopenic obesity". As highlighted by a recent systematic review and meta-analysis [Van Vgut 2017] all the studies on the impact of sarcopenia/sarcopenic obesity and myosteatosis in cirrhotic patients are retrospective studies, mostly involving non-consecutive patients on the list for liver transplantation. Moreover, most of the studies were produced by non-European centers (Canadians,Americans, and Japanese) that published more papers on the same patient series. All these factors have led to a possible selection bias. Furthermore, the methods used to evaluate sarcopenia and myosteatosis were not homogeneous (the entire muscle area, or area of the psoas or psoas diameter) as well as the cut-offs used. For these reasons, we propose a multicentric observational prospective study aimed at analyzing the impact of sarcopenia, sarcopenic obesity and myosteatosis in cirrhotic patients not listed for liver transplantation. Primary endpoint: - Evaluation of the impact of sarcopenia on the mortality of cirrhotic patients not on the waiting list for liver transplantation. Secondary end-point: Evaluation of the impact of sarcopenic obesity and myosteatosis on the mortality of cirrhotic patients not on the waiting list for liver transplantation. Evaluation of the impact of sarcopenia/sarcopenic obesity and myosteatosis on the development of complications (hepatic encephalopathy, bacterial infections, ascites, GI bleeding) in cirrhotic patients not on the waiting list for liver transplantation. Evaluation of the impact of sarcopenia/sarcopenic obesity and myosteatosis on the number of admissions and the days of hospitalization for such complications. Evaluation of the subcutaneous fat impact on mortality and morbidity of cirrhotic patients not on the waiting list for liver transplantation. Concordance analysis of the various methods used (different cut-off/area psoas vs. area of all muscles) for the diagnosis of sarcopenia through the analysis of CT scan.

General objectives of the project Defining healthy ageing factors; Setting up content-related bases of the international excellence centre (SLO-ITA) in the field of health of elderly citizens; Raising awareness on the significance of healthy ageing, social inclusion and mobility of less privileged populations (the elderly); Reducing the costs of health care; Connecting the existing health care, social and private entities and improving their mutual coordination.
