NCT04703647

Brief Summary

Complex regional pain syndrome (CRPS) is a post-traumatic chronic pain condition characterized by pain and other symptoms typically affecting a distal limb. Relatively little is known about the prognosis of the course of CRPS .Currently there is no specific test to diagnose CRPS. The primary objective of the study is to investigate prospectively the evolution of CRPS and the impact of the psychosocial factors on health status, recovery, quality of life, and working status of CRPS patients. The secondary objective of the study is to measure blood parameters in CRPS patients to investigate their evolution during the course of CRPS, and maybe to identify distinctive biomarkers associate with CRPS and that could be potential candidate for diagnosis.

Study Arms (2)

Patients with CRPS type 1: prospective group

Ambulatory patients of the Clinique romande de réadaptation (CRR) which have a CRPS type 1 of a limb. Five measurement times (first visit (T0) and then after 3 (T1), 6 (T2), 12 (T3) and 24 (T4) months). At every time point, following data will be collected: physical examination, monitoring of the health and professional status with the physician, and self-administrated questionnaires. Blood sampling will be performed at T0, T1,T2 and T3. Eight different self-administrated questionnaires will be used, in their French or Portuguese version. Each participants will answer seven questionnaires each time, depending if he/she suffers of arm or leg injury. We will assess, in blood samples, the expression levels of specific molecules (miRNAs and a selection of cytokines) in patients diagnosed with acute CRPS. In a second time, miRNAs and cytokines profiles will be compared between acute and chronic (CRPS still diagnosed 6 months after the first diagnosis) CRPS patients.

Other: Administration of questionnaires for prospective groupOther: Blood samples for prospective group

control group for blood analysis

For the blood analysis, we will recruit 30 healthy controls who did not report any kind of pain. They will be recruited via posters that will be posted on the billboards of the Hôpital de Sion (employees and visitors) and on the visitor's billboards of the CRR. If this is not enough, we will expand the recruitment perimeter with other locations. The healthy control will be adjusted for age, sex and BMI with the CRPS groups. They will be informed about the study and procedure. The procedure for the blood samples will be the same as for patients.The screening for miRNAs of interest will be performed using a decision tree-based ensemble method (Random Forest). For this step, miRNAs profile of 30 control patients will be compared to the same number of CRPS patients. The control group will have just one blood analysis.

Other: Blood samples for control group

Interventions

Questionnaires: administration at T0, T1,T2,T3 and T4 of Short Form Health Survey (SF-36),Brief Pain Inventory (BPI),Disabilities of the Arm, Shoulder and Hand (DASH) for upper limb,Foot and Ankle Ability Measure (FAAM) for lower limb,Hospital Anxiety And Depression Scale (HADS),Tampa Scale of Kinesiophobia (TSK),Pain Catastrophizing Scale (PCS),Pattern Of Activity Measure - Pain (POAM-P) .

Biospecimen

Retention: SAMPLES WITH DNA

For patients, blood samples will be collected at T0 (beginning of the study), T1 (3 months after T0) and, T2 (6 months after T0) and T3 (1 year after T0) by the study nurse (each time two 7.5 ml S-Monovette® K3 EDTA tubes).The samples will be first coded and then processed in our laboratory. After processing, samples will be stored at -80°C in a secured freezer. MiRNAs and various cytokines will be measured directly in our laboratory in Sion using previous validated protocols. For controls (30 patients) will be collected blood samples just one time for comparison with the patients. These same analysis than patients will be made.
