Well-being in amyotrophic lateral sclerosis: a pilot experience sampling study.

ABSTRACT:

Objective

The aim of this longitudinal study was to identify predictors of instantaneous well-being in patients with amyotrophic lateral sclerosis (ALS). Based on flow theory well-being was expected to be highest when perceived demands and perceived control were in balance, and that thinking about the past would be a risk factor for rumination which would in turn reduce well-being.

Methods

Using the experience sampling method, data on current activities, associated aspects of perceived demands, control, and well-being were collected from 10 patients with ALS three times a day for two weeks.

Results

RESULTS show that perceived control was uniformly and positively associated with well-being, but that demands were only positively associated with well-being when they were perceived as controllable. Mediation analysis confirmed thinking about the past, but not thinking about the future, to be a risk factor for rumination and reduced well-being.

Discussion

Findings extend our knowledge of factors contributing to well-being in ALS as not only perceived control but also perceived demands can contribute to well-being. They further show that a focus on present experiences might contribute to increased well-being.

Project description:BackgroundPatients with amyotrophic lateral sclerosis (ALS) suffer from dysphagia that increases the risk for aspiration, pneumonia and weight loss. Pharyngeal electrical stimulation (PES) is a therapeutic technique that applies electric stimuli to the patient's pharynx in order to improve swallowing based on the principle of cortical plasticity and reorganization. Previous studies have demonstrated positive effects in patients with various neurological diseases.ObjectiveThis study was initiated to investigate the effect of PES on swallowing function in patients with ALS.MethodsIn all, 20 ALS patients with severe dysphagia [characterized by a Penetration Aspiration Scale (PAS) of at least 4 in thin liquid] were randomized to receive either PES for 10 min at 3 consecutive days in addition to Standard Logopaedic Therapy (SLT) or SLT alone. Swallowing function was evaluated by Fiberoptic Endoscopic Evaluation of Swallowing (FEES) at five timepoints: at baseline, 1 day, 4 days, 3 weeks and 3 months after treatment. Primary endpoint was the severity of penetrations or aspirations as classified by PAS. Secondary endpoints were adverse events, dysphagia-related quality of life, Swallowing Quality of Life (SWAL-QOL), Dysphagia Severity Rating Scale (DSRS), residues, leaking, ALS Functional Rating Scale Revised (ALSFRS-R), and the performance in Clinical Evaluation of Swallowing (CES). The trial is registered under the name of 'Pharyngeal Electrical Stimulation in Amyotrophic Lateral Sclerosis' with ClinialTrials.gov, number NCT03481348 (https://clinicaltrials.gov/ct2/show/NCT03481348).ResultsBoth groups combined showed a significant improvement (p = 0.003) of median Total-PAS from 3.6 [interquartile range (IQR) = 2.9-5.0] at baseline to 2.3 (IQR = 1.8-4.0) 1 day after treatment. During subsequent study visits, PAS increased again but remained below baseline. PES and control group did not differ significantly 1 day after intervention (p = 0.32). Similar effects were found in the majority of secondary endpoints.InterpretationThe findings suggest that PES may not provide an additional positive effect on swallowing function in ALS. SLT seems to yield at least short-term positive effects on swallowing function and swallowing-specific life quality in ALS.Registration: ClinialTrials.gov: NCT03481348.

Project description:Background:Oligodendrocytes (OGs) provide metabolic support to motor neurons (MNs) and are implicated in the pathophysiology of amyotrophic lateral sclerosis (ALS). MD1003, or high-dose Pharmaceutical grade Biotin (hdPB), may improve disability in progressive multiple sclerosis patients via augmentation of OG or MN energy levels. Here, we assessed the safety and efficacy of MD1003 in ALS patients. Methods:This single centre, randomised, double-blind, placebo-controlled trial included patients aged 25-80 years with probable or definite ALS. Patients were assigned (2:1), using a computer-generated randomisation list, to receive oral MD1003 (300 mg/day) or placebo treatment for 24 weeks. The primary outcome, safety, was analysed in all patients who received at least one dose of study drug. This study, registered with ClinicalTrials.gov, NCT03114215, has been completed. Findings:Between June and December 2016, 30 patients were enrolled (MD1003, n = 20; placebo, n = 10). Baseline characteristics were representative of the ALS population. MD1003 and placebo groups were not well balanced at screening, with the MD1003-treated group having a higher rate of ALSFRS-R decline prior to screening versus placebo (-6·0 IQR [-8·5, -5·0] vs. -5·0 IQR [-5·0, -3·0]) and a predominance of ALS with upper limb onset compared to placebo (35% vs. 10%). MD1003 had a favourable safety profile and was well tolerated. The occurrence of adverse events was similar in both groups (60%). Two deaths occurred in the MD1003 group versus 1 in the placebo group. ALSFRS-R median change from baseline to month 6 was not significantly different between the two groups (p = 0·49); the mean difference between groups was -1·6 (SEM=3·3). Interpretation:MD1003 treatment was safe and well tolerated. It was not possible to establish MD1003 efficacy in this relatively small study. Given the favourable safety profile of MD1003 and an imbalance between treatment groups favouring placebo, additional, larger studies in ALS are warranted. Funding:MedDay Pharmaceuticals.
