Muscle-tendon weakness contributes to chronic fatigue syndrome in Gaucher's disease.

ABSTRACT: BACKGROUND:Chronic fatigue (CFg) is a prevalent symptom in Gaucher disease (GD) at diagnosis (79%) and remains in a quarter of patients after years of therapy. Bone abnormalities are present in over 70% and peripheral neuropathy in about 11% of the patients, which contributes to the disabling and debilitating complications. Our hypothesis is that other factors such as muscle-tendinous weakness could have influence in the development of CFg. METHODS:We have evaluated the fiber structure and elasticity of muscle-tendinous unit by strain-elastography (S-ELA) and analyzed their influence in the CFg. S-ELA study was performed in Achilles tendon in 25 type 1 and two type 3 GD patients, all of them with fatigue and were on enzymatic replacement therapy for mean 13 years; simultaneously, bone marrow burden by MRI and calcaneus ultrasound densitometry were evaluated. Blood cell counts, plasma biomarkers, GBA1 genotyping, and SF36 quality of life scale (QoL) were also performed. STATISTICAL ANALYSIS:descriptive and comparative test. RESULTS:All patients showed a normal Achilles tendinous structure. Abnormal stiff grade 2-3 was found in 17/27 (62.9%); in 11/27 (40.7%) of patients, the alteration was bilateral. There were no correlations between the S-ELA results to other variables; nevertheless, a significant correlation between the degree of tendon hardness and the low score on the QoL scales (p?=?0.0035) was found. The S-ELA is a sensitive painless, fast, and low cost method to detect muscle-tendinous subclinical dysfunction that could contribute to CFg in GD. The identification of subclinical tendon alteration would be a sign of alarm, focused on the risk of development of bone complications. CONCLUSION:Intratendinous alteration in strain-elastography is an independent variable in GD patients with persistent fatigue.

Project description:ImportanceChronic fatigue syndrome (CFS) is characterised by a constellation of symptoms diagnosed with a number of different polythetic criteria. Heterogeneity across these diagnostic criteria is likely to be confounding research into the as-yet-unknown pathophysiology underlying this stigmatised and debilitating condition and may diagnose a disease spectrum with significant implications for clinical management. No studies to date have objectively investigated this possibility using a validated measure of CFS symptoms-the DePaul Symptom Questionnaire (DSQ).ObjectiveTo examine whether current CFS diagnostic criteria are identifying different disease phenotypes using the DSQ.DesignCase control study.SettingClinical Research Facility of the Royal Victoria Infirmary, Newcastle upon Tyne, UK.Participants49 CFS subjects and ten matched, sedentary community controls, excluded for co-morbid depression.Main outcomes and measuresSelf-reported autonomic and cognitive features were assessed with the Composite Autonomic Symptom Score (COMPASS) and Cognitive Failures Questionnaire (COGFAIL) respectively. Objective autonomic cardiovascular parameters were examined using the Task Force® Monitor and a battery of neuropsychological tests administered for objective cognitive assessment.ResultsSelf-reported autonomic and cognitive symptoms were significantly greater in CFS subjects compared to controls. There were no statistically significant differences in objective autonomic measures between CFS and controls. There were clinically significant differences between DSQ subgroups on objective autonomic testing. Visuospatial memory, verbal memory and psychomotor speed were significantly different between DSQ subgroups.Conclusions and relevanceThe finding of no significant differences in objective autonomic testing between CFS and control subjects may reflect the inclusion of sedentary controls or exclusion for co-morbid depression. Consistent exclusion criteria would enable better delineation of these two conditions and their presenting symptoms. Findings across CFS subgroups suggest subjects have a different disease burden on subjective and objective measures of function, autonomic parameters and cognitive impairment when categorised using the DSQ. Different CFS criteria may at best be diagnosing a spectrum of disease severities and at worst different CFS phenotypes or even different diseases. This complicates research and disease management and may contribute to the significant stigma associated with the condition.

Project description:Background:Sarcopenia is a prognostic factor for patients with liver cirrhosis and hepatocellular carcinoma, and it affects the onset of hepatic encephalopathy. Therefore, the prevention of sarcopenia contributes to the improvement of the prognosis of patients with chronic liver disease (CLD). We focused on changes of hand grip strength (HGS), one of the indicators of sarcopenia. However, there are little data investigating the impact of physical activity (PA) on HGS in patients with CLD. This study aimed to clarify whether PA contributes to the prevention of muscle weakness in patients with CLD. Methods:This was a prospective observational study. We examined the effect of PA on changes in HGS from the baseline to the endpoint in each group. Metabolic equivalents-hour/week (METs-h/w) was used to evaluate PA. In total, 183 outpatients with CLD were analyzed. We divided participants into four groups (low PA in younger patients (n = 20), high PA in younger patients (n = 33), low PA in elderly patients (n = 47), and high PA in elderly patients (n = 83)). Results:Fifty-eight percent of patients were men, and the median (interquartile range) age was 69.0 (63.0, 75.0) years. The most common etiology of liver disease was hepatitis C (38%). The frequency of living alone and low exercise habit was significantly high, and sarcopenia was more obvious in elderly patients with low PA than in those with high PA. Additionally, the elderly with low PA showed significantly reduced HGS compared to that of the elderly with high PA (-1.00 (-2.27, 0.55) kg vs. 0.10 (-1.40, 1.10) kg, P < 0.05). However, changes in HGS in younger patients were not significant (-0.02 (1.83, 1.47) kg vs. 0.25 (-2.45, 2.05) kg, P = 0.96). Logistic regression analyses identified PA as the independent factor for prevention of decrease in HGS (odds ratio: 1.91, 95% confidence interval: 1.00 - 3.62, P = 0.049). Conclusions:Young patients with low PA were characterized by a long sedentary time; however, there was no loss of HGS. In contrast, elderly patients with CLD and low PA had significantly reduced HGS compared to that in elderly patients with CLD and high PA.
