Filter by:In humans, alcohol-related dysbiosis exists with a decrease in bacteroides. This dysbiosis is responsible for the breakdown of the intestinal barrier by a decrease in the synthesis of protective mucus, and some proteins involved in tight junctions or a decrease in defensin (Reg3b, Reg3g) which promotes bacterial growth and ultimately bacterial translocation. The microbiota of a patient with alcoholic hepatitis is different from that of a patient without alcoholic hepatitis. Acute alcoholic hepatitis has a severe prognosis and corticosteroids are the only first line therapy option, with better survival at 28 days versus placebo. However, mortality remains high at 30% at 3 months, which highlights the importance of seeking intestinal microbiota profile on treatment response. The determination of one or more intestinal microbiota signatures associated with the treatment response Corticosteroids plus FMT or Corticosteroids plus placebo will allow the clinician to have a simple and rapid test obtained in 16S RNA analysis to predict the therapeutic response and potentially the best treatment to adopt and to address medical and medico-economic stakes. The investigators will first characterize the alcohol-induced dysbiosis by a whole microbiota sequencing in the different groups. Specific bacterial species identify by DNA sequencing should be confirmed by qPCR of 16S rDNA to determine a fingerprint of sAH microbiota. Metabolic properties of intestinal microbiota, such as production of short chain fatty acids, will be analyzed by using HPLC. In the sAH group, evolution of intestinal microbiota will be observed by shotgun DNA sequencing between the day 0 and the day 7 of corticosteroids treatment. The analysis of sAH patients' microbiota (day 0) will allow us to obtain a non-responder profile to corticosteroids that can be used as a prognostic marker to use in the clinic. The deliverable is the bacterial fingerprint of the treatment response and its valuation is its use as a predictive tool of the response.
Rationale: Synthetic glucocorticoids can result in neuropsychiatric adverse effects in a minority of patients. Although, not all patients experience severe adverse effects, more subtle emotional disturbances are often experienced. With a variation on ecological momentary assessment (EMA), with a daily assessment, the investigators will collect the patient's emotional symptoms in real time and in the patients natural environment during corticosteroid treatment. With dynamic time warping (DTW) analysis the investigators aim to analyse the temporal dynamics of different emotional states and visualize these emotional dynamics over time. The patient dermatologist and neurologist will receive the idiographic results as a feedback form, which may give insights into temporal (and possibly causal) central emotions, which may help to overcome mood disturbances. Objective: Mapping emotional dynamics with DTW analysis in 6 mycosis fungoides or Sezary syndrome patients and 6 chronic cluster headache patients treated with systemic corticosteroids. Study design: Case series report study. Study population: Six patients with cutaneous T-cell lymphoma (type mycosis fungoides and/or Sezary syndrome), and six patients with cluster headache. Main study parameters/endpoints: An idiographic DTW analysis of emotional dynamics during and after corticosteroid treatment in six mycosis fungoides and/or Sezary syndrome patients, and six chronic cluster headache patients. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: There are no additional risks associated with study participation. The patients who will participate in this case series study need to complete a 5-minute survey daily using a m-Path smartphone app during corticosteroid treatment. The data analysis may increase the insight into centrality measures of emotions and the emotional clusters for the individual patient.
Thoracic surgery is at high risk of respiratory complications. Despite the improvement of surgical procedures such as video-thoracoscopy, respiratory complications appear in 15 to -20% of procedures. Thoracic surgery induces local pulmonary inflammation which is involved in the occurrence of post-operative respiratory failure. Similarly to the example of the acute respiratory distress syndrome, corticosteroids could reduce lung injury secondary to immunological stress. In addition, recent studies suggest that dexamethasone could lead to a reduction of respiratory complications after major non cardiothoracic surgery. Since dexamethasone is recommended to prevent postoperative nausea and vomiting, around one in two patients receive dexamethasone during anesthetic induction. By retrospective analysis with compensation of bias by propensity score, the investigators aim to assess the effect of dexamethasone to prevent respiratory complications
