Objectives

Narrative objectives1

The primary objective is to understand the relationship between physical activity and the clinical expression of sickle cell disease. A secondary aim is to study the relationship between physical activity and the physiological factors known to be involved in the occurrence of vaso-occlusive events. Finally, the effect of an increase in physical activity on the course of the disease will be investigated.

Assessment

Primary outcomes

- physical activity parameters (step-count, physical activity intensity), assessed daily and objectively using an activity tracker.
- pain, assessed every day using a pain diary.
- vaso-occlusive events and associated clinical signs.
These primary outcomes are assessed on a minimum experimental period of 30 days.

Key secondary outcomes

- level of physical activity, using questionnaires.
- quality of life, using questionnaires.
- walking speed.
- cardio-vascular function (pulse wave velocity, hear rate variability).
- hematological parameters.
- biochemistry parameters.
- inflammation parameters (cytokines, vascular adhesion molecules, micro-particles).
- hemorheological parameters (blood and plasma viscosities).
- sleep quality (assessed every day using an activity tracker).
These secondary outcomes are assessed at the beginning or at the end of each 30-day experimental period (unless specified otherwise in the above).

Gender

Male and Female

Key inclusion criteria

- patients with confirmed sickle cell disease.
- willing to participate to the study (written informed consent).

Key exclusion criteria

- no transfusion for the 2 months proceeding the study.
- no vaso-occlusive crisis or acute chest syndrome for the 3 months preceding the study.
- absence of leg ulcer, osteonecrosis of the femoral head.
- absence of any condition impairing walking gait.

Patients presenting a median daily step-count over 9000 or an average daily step-count over 10.000 at the end of the baseline period are not allocated to one of the trial arms. Their baseline data will be treated in a cross-sectional analysis.
