Nutrition Intervention for Chronic Pain Patients

Not Applicable

Completed

• Conditions: Chronic Pain
• Interventions: Other: Nutrition Education

• Registration Number: NCT03837080
• Lead Sponsor: Josip Juraj Strossmayer University of Osijek

Brief Summary

The primary objective of the study is to determine the effectiveness of nutrition education (individual and group) on the intensity of pain in patients suffering from chronic pain. The secondary goal is to determine whether there is a change in the status of the patient's nutrition, their quality of life, quality of life, and other indicators of the psychophysical condition of the patient.

Detailed Description

The underlying hypothesis of the study is that patients with chronic pain that go through a series of nutrition education (individual and group) specifically tailored to fit their needs (based on our preliminary findings), they increase the consumption of foods that have antiinflammatory properties, which will result in lower levels of inflammatory cytokines in the body (high sensitivity C-reactive protein (hs-CRP ), interleukin (IL) -2, IL-4 and IL-6), and consequently reduce the intensity of pain. Also, weight loss in obese patients is expected, and it will have an contributing effect of the intervention. Patient's quality of life and indicators of their psychophysical condition (eg, depression level) are also expected to improve.

Chronic pain patients who either attend Daily clinic (Control Arm) or the 4-week multidisciplinary programme at the Department of Anesthesiology, Resuscitation and Intensive Care (Intervention Arm) will be recruited. They will be followed for total of 8 weeks (4 week intervention + 4 week follow-up).

Arm && Interventions

Group	Intervention	Description
Nutrition Education	Nutrition Education	Participants suffering from chronic pain enrolled in the 4-week Pain Management Clinic organized at the Department of Anesthesiology, Resuscitation and Intensive Care will go through a series of individual and group nutrition educations. Educations are specifically tailored for chronic pain patients, based on our preliminary findings on this group of patients.

Primary Outcome Measures

Name	Time	Method
Change in pain intensity after the intervention and after 4-week follow-up	At inclusion, 4 weeks after the intervention, 4 weeks post-intervention	We will use simple, patient-based pain screening questionnaire called the painDETECT questionnaire (validated and widely used to assess pain intensity in chronic pain patients). The questionnaire is based on the scale from 1 (no pain) to 10 (extreme pain).

Secondary Outcome Measures

Name	Time	Method
Change in interleukines after the intervention and after 4-week follow-up	At inclusion, 4 weeks after the intervention, 4 weeks post-intervention	IL-2 (pg/mL), IL-4 8pg/mL), IL-6 (pg/mL)
Change in high-sensitive C-reactive protein after the intervention and after 4-week follow-up	At inclusion, 4 weeks after the intervention, 4 weeks post-intervention	high sensitive C-reactive protein (hs-CRP) (mg/L),
Change in monocyte chemoattractant protein after the intervention and after 4-week follow-up	At inclusion, 4 weeks after the intervention, 4 weeks post-intervention	Monocyte chemoattractant protein (MCP-1) (pg/mL)
