Pain Mechanisms in Patients With Bronchiectasis

29 januari 2019 bijgewerkt door: Víctor Doménech, Universidad San Jorge

Characteristics of Underlying Pain Mechanisms in Patients With Bronchiectasis: a Cross-sectional Study

Pain mechanisms and their clinical impact in patients with bronchiectasis have not been investigated yet. The aim of the research is to assess the presence of central pain mechanisms in patients with bronchiectasis using the Quantitative Sensory Testing (QST) assumptions.

Gedetailleerde beschrijving

Background and objective:

Recent findings suggest that pain can play an important role in terms of physical activity limitation in respiratory patients. Nevertheless, pain mechanisms and their clinical impact in patients with bronchiectasis have not been investigated yet. The objective of the observational study is to determine the somatosensorial profile in order to assess the presence of central pain mechanisms in patients with bronchiectasis.

Methodology:

Repeated-measures prospective cross-sectional study. A sample of patients diagnosed with bronchiectasis will be recruited and matched by age and sex with healthy controls. Pressure pain thresholds (PPTs), conditioned pain modulation (CPM) and referral pain will be assessed before and after the Incremental Shuttle Walking test (ISW). Levels of physical activity will be assessed using accelerometry during a 7-days period. Sleep quality (Pittsburgh sleep quality test), level of catastrophizing (Pain Catastrophizing Scale), level of sensitization (Central Sensitization Inventory) and level of anxiety and depression (Hospital Anxiety and Depression) will be assessed. The assessments will be done twice: 1) at baseline; and 2) at 6 months follow-up period.

Wat meet het onderzoek?

Primaire uitkomstmaten

Uitkomstmaat
Maatregel Beschrijving
Tijdsspanne
Referred pain area
Tijdsspanne: Baseline
Amount of pixels painted in an electronic body chart (Navigate Pain, Aalborg, Denmark) after supra threshold pain stimulus (STPS) in infraspinatus muscle.
Baseline

Secundaire uitkomstmaten

Uitkomstmaat
Maatregel Beschrijving
Tijdsspanne
Number of body areas affected by referred pain
Tijdsspanne: Baseline
Body chart is divided in 15 regions and the frequency of pain in each one is registered after STPS
Baseline
Pain intensity after supra threshold pain stimulus (STPS)
Tijdsspanne: Baseline
Level of pain in a visual analogue scale from 0 to 10 after STPS
Baseline
Pressure pain thresholds (PPTs)
Tijdsspanne: Baseline
Level of pressure tolerated by the patient just before feel pain. The pressure is done with an algometer (SB-MEDIC Electronics, Solna, Sweden). PPTS will be assessed bilaterally in infraspinatus, supraspinatus and medial gastrocnemius muscles.
Baseline
PPTs with a Conditioned Pain Modulation (CPM) pressure stimulus
Tijdsspanne: Baseline
Level of pressure tolerated by patient just before feel pain. The conditionated pressure stimulus is preform by a blood pressure cuff. CPM will be assessed bilaterally in infraspinatus, supraspinatus and medial gastrocnemius muscles.
Baseline
Total physical activity time
Tijdsspanne: 7 days period
Total time spent per day in physical activities at different intensities equal or superior to 100 counts per minute (≥100 cpm), obtained by accelerometry (Actigraph gt3x+).
7 days period
Sedentary behaviour time
Tijdsspanne: 7 days period
Total time spent per day in physical activities at different intensities inferior to 100 cpm (<100 cpm).
7 days period
Light physical activity time
Tijdsspanne: 7 days period
Total time spent per day in physical activities at intensities between 100 and 1951 cpm (100-1951 cpm).
7 days period
Moderate-Vigorous physical activity time
Tijdsspanne: 7 days period
Total time spent per day in physical activities at intensities equal or superior to 1952 cpm (≥1952 cpm).
7 days period
Level of catastrophizing
Tijdsspanne: Baseline
Punctuation obtained in Pain Catastrophizing Scale (PCS). It comprises 13 items which focus on thoughts and feelings encountered while experiencing pain. Each item is scored from 0 (not at all) to 4 (all the time) with a total PCS score range from 0-52 points, where higher scores indicating higher levels of pain catastrophizing.
Baseline
Level of sensitization
Tijdsspanne: Baseline
Punctuation obtained in Central Sensitization Inventory (CSI). CSI assesses 25 health-related symptoms common to Central Sensitivity Syndromes. Responses are recorded about the frequency of each symptom, with a Likert scale from 0 (never) to 4 (always), resulting in a total possible score of 100. Higher scores are associated with a higher degree of self-reported symptomology.
Baseline
Level of anxiety and depression
Tijdsspanne: Baseline
Punctuation obtained in Hospital Anxiety and Depression (HAD). The HAD is a 14-item self-report scale measuring the presence of symptoms of both anxiety (seven items) and depression (seven items) during the past week. Each item is scored from 0 to 3, so the final score for each subscale is between 0 and 21. The majority of the studies use the cutoffs of 7/8 for possible and 10/11 for probable anxiety or depression.
Baseline
Quality of sleep
Tijdsspanne: Baseline
Punctuation obtained in Pittsburgh Sleep Quality Index (PSQI). The PSQI is a 19-item, self-rated questionnaire designed to measure sleep quality and disturbance over the past month in clinical populations. Each sleep component yields a score ranging from 0 to 3, with 3 indicating the greatest dysfunction. Sleep component scores were summed to yield a total score ranging from 0 to 21 with the higher total score (referred to as global score) indicating worse sleep quality.
Baseline
Level of resilience
Tijdsspanne: Baseline
Punctuation obtained in Brief Resilience Scale (BRS). This is a 6-item self-report scale with a 5-point response scale ranging from 1 (strongly disagree) to 5 (strongly agree). A higher score indicates a higher degree of resilience.
Baseline
Distance in ISW test
Tijdsspanne: Baseline
Meters reached in the ISW test.
