Chronic Obstructive Pulmonary Disease (COPD) is characterized by persistent airway obstruction and inflammatory response of the lungs and bronchi. Episodes of exacerbations contribute to increase the severity and prognosis of the disease. Muscle dysfunction (loss of strength and muscle mass) is one of comorbidities affecting 30% to 60% of patients and playing a key role in their prognosis. Indeed, several studies have shown muscle weakness during hospitalization for exacerbation of COPD by measure of maximal voluntary contraction of quadriceps (MVCQ), but the results are variable from one patient to another. Moreover, no study was interested in the change of muscle mass in patients hospitalized for an exacerbation of COPD. Several mechanisms have been mentioned but not demonstrated: systemics factors (initial amyotrophy, inflammation, oxidative stress, corticotherapy, hypoxia…) but also physical inactivity. In this context, identifying factors associated with the onset of muscle weakness during hospitalization for exacerbation of COPD is a necessary step to better understand the mechanisms and consider a personalized therapeutic approach that can improve the functional and clinical prognosis of disease. The primary outcome is to identify the clinical and biological determinants associated with the onset of amyotrophy (Measure by ultrasound of sectional area of the Rectus Femoris, CSARF), during hospitalization for exacerbation of COPD. The secondary outcome is to identify the clinical and biological determinants associated with the onset of MVCQ decrease, during hospitalization for exacerbation of COPD. 120 patients hospitalized for exacerbation of COPD will be recruited in two hospitals (CHU Montpellier - CHU Grenoble, FRANCE). The measures of CSARF and MVCQ are carried out on the second, fifth, eighth day of hospitalization, on discharge and on the sixtieth day after hospitalization. A blood test will be performed on the second day of hospitalization to explore different markers of inflammation and oxydative stress. Moreover, to quantify the level of physical activity (number of steps), each patient will carry a pedometer throughout the duration of hospitalization. At the end of protocol, two groups will be made from the median of CSARF : patients with a small reduction in CSARF compared to patients with a greater reduction in SSRF between the second and eighth days of hospitalization (or between the second day of hospitalization and discharge). Then clinical (comorbidities, severity disease, initial weakness, initial amyotrophy, usual physical activity before hospitalization, treatment, exacerbation number in the previous year…) and biological (markers of inflammation and oxydative stress) determinants were compared between the two groups. Thus, the identification of the determinants associated with the onset of amyotrophy induced during exacerbation of COPD will guide research for exploration of physiopathological mechanisms of this muscular dysfunction in the exacerbation of COPD as well as to identify a personalized support.
Spinal muscular atrophy (SMA) are one of the common physical disabilities in childhood. For SMA, progressive muscle weakness and early fatigue hamper the mobility of the sufferers. Osteopenia is common for this population group due to poor bone growth and muscle disuse. As a result, non-traumatic related fractures and bone pain are common. Recently, whole body vibration therapy (WBVT) has been proven to improve bone health and muscle function in healthy adults and post-menopausal women. Among the limited studies on the WBVT for children with muscular dystrophies, promising results have been shown on gross motor function, balance, and muscle strength and the WBVT appears to be safe for children with SMA. The present pilot study is designed to investigate if WBVT is safe and feasible for individuals with SMA and if WBVT can improve muscle function, functional abilities, postural control and bone mineral density in children with SMA. Convenience samples of 10 individuals with SMA type III will be recruited. The participants will receive the WBVT of 25 Hertz and a peak-to-peak amplitude of 4mm for a session of about 18 minutes, 3 days per week for 4 weeks. Assessment will be performed at the baseline and the completion of the intervention to examine the muscle function, functional abilities, postural control and bone mineral density of the participants. It is anticipated that the outcomes of this pilot study for SMA may show if this intervention is safe, feasible and beneficial for children with SMA type III regarding to muscle function, functional abilities, postural control and bone mineral content and if there may be any related practical issues of this intervention to this population group. The outcomes also provide research evidence to clinicians if this intervention should be recommended to individuals of similar problems.
Several factors make the use of celecoxib in human SMA patients appealing including: 1) low-dosing required for potential therapeutic effect (the corresponding dose in humans is much lower than that commonly used in adults and children with; 2) favourable side effect profile of this drug (particularly at the dosing required); 3) the fact that celecoxib crosses the blood brain barrier and 4) demonstration of efficacy in a genetically and pathophysiologically faithful animal mode. The investigators therefore believe that celecoxib is a promising disease modifying therapy for SMA.
Spinal Muscular Atrophy (SMA) is a neuromuscular disorder characterized by loss of motor neurons in the anterior horn of the spinal cord and leading to muscle atrophy. SMA has an autosomal recessive inheritance and affects 1 in 6000 infants with a carrier frequency of 1 in 40. In most cases, it is caused by homozygous gene deletion or gene conversion of the SMN1 gene (0+0 genotype) on 5q11-q13. This genomic region has been duplicated and inverted during evolution. Thus the SMN1 gene has a very homologous copy, called SMN2. Genetic counseling aim at detecting carriers with only one copy of the SMN1 gene (0+1 genotype). SMA carrier testing relies on total copy number quantification of the SMN1 copies by quantitative PCR methods. Nevertheless, cis-duplication of the SMN1 gene on one allele and deletion on the second allele (2+0 genotype) can lead to a misinterpretation as molecular methods show 2 copies of the SMN1 gene and cannot detect the carrier status. The aim of the study is the characterization of a biomarker specific of the cis-duplication of the SMN1 gene in order to allow the detection of this 2+0 genotype which constitutes a trap for genetic counseling. We will use molecular combing to identify a genomic morse code (GMC) composed of a combination of probes specific of a structural motif on the cis-duplication chromosome. The characterization of this GMC is based on the comparison of two sample groups: - The test group, with a maximum of 137 individuals carrying 3 copies of the SMN1 gene (suggesting a cis-duplication on one allele) - The control-1 group, with a maximum of 137 individuals carrying 2 copies of the SMN1 gene A pilot study performed on 24 samples in the two groups is needed to define the exact sample number necessary for statistical analysis of the study. When the GMC will be characterized, its specificity will be evaluated by testing two sample groups: - The test group, with 37 individuals carrying 3 copies of the SMN1 gene - The control-2 group, with 37 individuals carrying 3 copies of the SMN2 gene Molecular combing needs long DNA fibers and usual methods for DNA extraction are not appropriate. This project requires new blood samples for specific DNA extraction. If this project is successful, during a second project, this GMC will be converted into a simple and cheap PCR-based method. We will then evaluate the sensitivity of this method on our sample collection, notably on individuals with the 2+0 genotype defined by familial genotyping.
