    • Introduction Chronic breathlessness is highly prevalent and distressing to patients and families. No medication is registered for its symptomatic reduction. The strongest evidence is for regular, low-dose, extended-release (ER) oral morphine. A recent large phase III study suggests the subgroup most likely to benefit have chronic obstructive pulmonary disease (COPD) and modified Medical Research Council breathlessness scores of 3 or 4. This protocol is for an adequately powered, parallel-Arm, placebo-controlled, multisite, factorial, block-randomised study evaluating regular ER morphine for chronic breathlessness in people with COPD. Methods and analysis The primary question is what effect regular ER morphine has on worst breathlessness, measured daily on a 0-10 numerical rating scale. Uniquely, the coprimary outcome will use a FitBit to measure habitual physical activity. Secondary questions include safety and, whether upward titration after initial benefit delivers greater net symptom reduction. Substudies include longitudinal driving simulation, sleep, caregiver, health economic and pharmacogenetic studies. Seventeen centres will recruit 171 participants from respiratory and palliative care. The study has five phases including three randomisation phases to increasing doses of ER morphine. All participants will receive placebo or active laxatives as appropriate. Appropriate statistical analysis of primary and secondary outcomes will be used. Ethics and dissemination Ethics approval has been obtained. Results of the study will be submitted for publication in peer-reviewed journals, findings presented at relevant conferences and potentially used to inform registration of ER morphine for chronic breathlessness. Trial registration number NCT02720822; Pre-results.

  • Regular, sustained-release morphine for chronic breathlessness : A multicentre, double-blind, randomised, placebo-controlled trial
  • 2020

    • Introduction Morphine may decrease the intensity of chronic breathlessness but data from a large randomised controlled trial (RCT) are lacking. This first, large, parallel-group trial aimed to test the efficacy and safety of regular, low-dose, sustained-release (SR) morphine compared with placebo for chronic breathlessness. Methods Multisite (14 inpatient and outpatient cardiorespiratory and palliative care services in Australia), parallel-arm, double-blind RCT. Adults with chronic breathlessness (modified Medical Research Council≥2) were randomised to 20 mg daily oral SR morphine and laxative (intervention) or placebo and placebo laxative (control) for 7 days. Both groups could take ≤6 doses of 2.5 mg, â € as needed', immediate-release morphine (≤15 mg/24 hours) as required by the ethics review board. The primary endpoint was change from baseline in intensity of breathlessness now (0-100 mm visual analogue scale; two times per day diary) between groups. Secondary endpoints included: worst, best and average breathlessness; unpleasantness of breathlessness now, fatigue; quality of life; function; and harms. Results Analysed by intention-to-treat, 284 participants were randomised to morphine (n=145) or placebo (n=139). There was no difference between arms for the primary endpoint (mean difference -0.15 mm (95% CI -4.59 to 4.29; p=0.95)), nor secondary endpoints. The placebo group used more doses of oral morphine solution during the treatment period (mean 8.7 vs 5.8 doses; p=0.001). The morphine group had more constipation and nausea/vomiting. There were no cases of respiratory depression nor obtundation. Conclusion No differences were observed between arms for breathlessness, but the intervention arm used less rescue immediate-release morphine. Trial registration number ACTRN12609000806268.

  • Brain Magnetic Resonance Imaging Findings Fail to Suspect Fabry Disease in Young Patients With an Acute Cerebrovascular Event
  • 2015
  • Ingår i: Stroke. - : Ovid Technologies (Wolters Kluwer Health). - 0039-2499 .- 1524-4628. ; 46:6, s. 1548-

    • Background and Purpose-Fabry disease (FD) may cause stroke and is reportedly associated with typical brain findings on magnetic resonance imaging (MRI). In a large group of young patients with an acute cerebrovascular event, we wanted to test whether brain MRI findings can serve to suggest the presence of FD. Methods-The Stroke in Young Fabry Patients (SIFAP 1) study prospectively collected clinical, laboratory, and radiological data of 5023 patients (18-55 years) with an acute cerebrovascular event. Their MRI was interpreted centrally and blinded to all other information. Biochemical findings and genetic testing served to diagnose FD in 45 (0.9%) patients. We compared the imaging findings between FD and non-FD patients in patients with at least a T2-weighted MRI of good quality. Results-A total of 3203 (63.8%) patients had the required MRI data set. Among those were 34 patients with a diagnosis of FD (1.1%), which was definite in 21 and probable in 13 cases. The median age of patients with FD was slightly lower (45 versus 46 years) and women prevailed (70.6% versus 40.7%; P<0.001). Presence or extent of white matter hyperintensities, infarct localization, vertebrobasilar artery dilatation, T1-signal hyperintensity of the pulvinar thalami, or any other MRI finding did not distinguish patients with FD from non-FD cerebrovascular event patients. Pulvinar hyperintensity was not present in a single patient with FD but seen in 6 non-FD patients. Conclusions-Brain MRI findings cannot serve to suspect FD in young patients presenting with an acute cerebrovascular event. This deserves consideration in the search for possible causes of young patients with stroke.

  • Controlled-Release Oxycodone vs. Placebo in the Treatment of Chronic Breathlessness—A Multisite Randomized Placebo Controlled Trial
  • 2020
  • Ingår i: Journal of Pain and Symptom Management. - : Elsevier BV. - 0885-3924. ; 59:3, s. 581-589
  • Tidskriftsartikel (refereegranskat)abstract
    • Context: Chronic breathlessness is a clinical syndrome that results in significant distress and disability. Morphine can reduce chronic breathlessness when the contributing etiologies are optimally treated. Objectives: Does oxycodone reduce chronic breathlessness compared with placebo? Methods: A multisite, randomized, placebo-controlled, double-blind, parallel-arm, fixed-dose trial of oral controlled-release oxycodone 15 mg (5 mg, eight hourly) or placebo (ACTRN12609000806268 at www.anzctr.org.au). As-needed immediate-release morphine (2.5 mg per dose; six and less doses/day) was available for both arms as required by one ethics committee overseeing the trial. Recruitment occurred from 2010 to 2014 in 14 inpatient and outpatient respiratory, cardiology, and palliative care services across Australia. Participants were adults, with chronic breathlessness (modified Medical Research Council Scale 3 or 4), who were opioid naive. The primary end point was the proportion of people with greater than 15% reduction from baseline in the intensity of breathlessness now (0–100 mm visual analogue scale) comparing arms Days 5–7. Secondary end points were average and worst breathlessness, quality of life, function, and harms. Results: Of 157 participants randomized, 155 were included (74 oxycodone and 81 placebo), but the study did not reach target recruitment. There was difference in neither between groups for the primary outcome (P = 0.489) nor any of the prespecified secondary outcomes. Placebo participants used more as-needed morphine (mean 7.0 vs. 4.2 doses; P ≤ 0.001). Oxycodone participants reported more nausea (P < 0.001). Conclusion: There was no signal of benefit from oxycodone over placebo. Future research should focus on investigating the existence of an opioid class effect on the reduction of chronic breathlessness.

  • Physical activity in the elderly is associated with improved executive function and processing speed: the LADIS Study
  • 2015
  • Ingår i: International Journal of Geriatric Psychiatry. - : Wiley. - 0885-6230 .- 1099-1166. ; 30:7, s. 744-750

    • ObjectivesPhysical activity reduces the risk of cognitive decline but may affect cognitive domains differently. We examined whether physical activity modifies processing speed, executive function and memory in a population of non-dementia elderly subjects with age-related white matter changes (ARWMC). MethodsData from the Leukoaraiosis And DISability (LADIS) study, a multicenter, European prospective cohort study aimed at examining the role of ARWMC in transition to disability, was used. Subjects in the LADIS study were clinically assessed yearly for 3years including MRI at baseline and 3-year follow-up. Physical activity was assessed at baseline, and cognitive compound scores at baseline and 3-year assessment were used. ResultsTwo-hundred-eighty-two subjects (age, y (mean (SD)): 73.1 (5.1); gender (f/m): 164/118); MMSE (mean (SD)): 28.3 (+/- 1.7)) who had not progressed to MCI or dementia, were included. Multiple variable linear regression analysis with baseline MMSE, education, gender, age, stroke, diabetes and ARWMC rating as covariates revealed that physical activity was associated with better scores at baseline and 3-year follow-up for executive function (baseline: : 0.39, 95% CI: 0.13-0.90, p=0.008; follow-up: : 0.24, 95% CI: 0.10-0.38, p=0.001) and processing speed (baseline: : 0.48, 95% CI: 0.14-0.89, p=0.005; follow-up: : 0.15, 95% CI: 0.02-0.29, p=0.02) but not memory. When including baseline cognitive score as a covariate in the analysis of 3-year follow-up scores, executive function remained significant (: 0.11, 95% CI: 0-0.22, p=0.04). ConclusionOur findings confirm previous findings of a positive effect of physical activity on cognitive functions in elderly subjects, and further extends these by showing that the association is also present in patients with ARWMC.
