EHCO: Embolization in Hereditary Coagulopathies
Study Details
Study Description
Brief Summary
This is a longitudinal, prospective study, which will include 30 subjects with hereditary coagulopathies, with arthropathy, chronic synovitis resulting from hemarthrosis of the elbows, knees and/or ankles followed up at the Centro de Hemofilia HCFMUSP, after approval by the ethics and research committee.
They will undergo imaging tests (X-rays and Magnetic Resonance of knee, elbow, or ankle), physical, pain, quality of life and functional assessments (Hemophilia Joint Health Score, Functional Independence Score in Hemophilia, Perimeter, Test Timed up and Go, 30 second sit and stand test, Haemophilia - Adult - Quality of Life questionnaire (HAEM-A-QoL), Knee Injury and Osteoarthritis Outcome Score, EQ-5D, numerical rating scale for pain and embolization procedure (superselective embolization of target arteries with spherical microparticles Embosphere 100-300 micrometers (Biosphere Medical, Roissy, France), until partial vascular stasis and decharacterization of pathological synovial enhancement.
These evaluations will be performed at baseline, 1, 3, 6, 12, 24, 36, 48 and 60 months after the procedure.

Detailed Description
Longitudinal, prospective study, which will include 30 subjects with hereditary coagulopathies, with arthropathy, chronic synovitis resulting from hemarthrosis of the elbows, knees and/or ankles followed up at the Centro de Hemophilia do Hospital das Clinicas, Faculdade de Medicina da Universidade de São Paulo, i.e. HC-FMUSP), after approval by the ethics and research committee and registry at the clinical trials.
Patients will be evaluated by imaging (X-rays and Magnetic Resonance of the affected joint, i.e., knee, elbow, and/or ankle); physical and functional assessments (Hemophilia Joint Health Score, Functional Independence Score in Hemophilia, Perimeter of the affected joint(s), Test Timed up and Go, 30 second sit and stand test, Knee Injury and Osteoarthritis Outcome Score (KOOS); quality of life (Haemophilia - adult - quality of life questionnaires (HAEM-A-QoL), Knee Injury and Osteoarthritis Outcome Score (KOOS), EQ-5D; pain measured by numerical rating scale.
Volunteers will be submitted to embolization procedure (superselective embolization of target arteries with spherical microparticles embosphere 100-300 micrometers (Biosphere Medical, Roissy, France) of the affected joint(s), until partial vascular stasis and decharacterization of pathological synovial enhancement.
These evaluations will be performed at baseline, 1, 3, 6, 12, 24, 36, 48 and 60 months after the procedure.

Outcome Measures
Primary Outcome Measures
- Reduction of synovium thickness by embolization [6 months]
Measure (in milimeters) changes of synovial thickness in patients with hereditary coagulopathies with arthropathy due to hemarthrosis with MRI (measure synovium thickness)
Secondary Outcome Measures
- Reduction of synovitis by embolization [1, 3 12, 24, 36, 48 and 60 months]
Measure (in milimeters) changes on synovial thickness in patients with hereditary coagulopathies with arthropathy due to hemarthrosis with MRI
- Inferior limb strength [1, 3, 6, 12, 24, 36, 48, 60 months]
Measure changes in muscle strength by timed up and go (by time of performance, in seconds).
- Inferior limb strength [1, 3, 6, 12, 24, 36, 48, 60 months]
Measure changes in muscle strength of lower limbs by 30 seconds sit to stand test (by number of repetitions)
- Balance and fall risk [1, 3, 6, 12, 24, 36, 48, 60 months]
Measure (in seconds, period of time to perform the test) changes in balance and risk of falls by Timed up and go test.
- Quality of life of the patient [1, 3, 6, 12, 24, 36, 48, 60 months]
Measure, according to the scale of the questionnaire, changes in quality of life with Haemophilia - Adult - Quality of life Questionnaires (HAEM-A-QoL, 10 dimensions, 0 to 100, being 0 the best health related quality of life)
- Quality of life of the patient [1, 3, 6, 12, 24, 36, 48, 60 months]
Measure, according to the scale of the questionnaire, changes in quality of life with Knee Injury and Osteoarthritis Outcome Score (KOOS, 0-100, 100 being the best quality of life).
- Quality of life of the patient [1, 3, 6, 12, 24, 36, 48, 60 months]
Measure, according to the scale of the questionnaire, changes in quality of life with by EQ-5D, up to 1, being 1 the best quality of life). Please note: "Since 2009, EQ-5D has been available in three versions: the three-level EQ-5D-3L; the five-level EQ-5D-5L; and a 'youth' adaptation, EQ-5D-Y. Although the EQ is in recognition of the EuroQol group name, the D refers to dimensions, the L signifies level, and the Y stands for youth, the name of the instrument should not be spelled out in this manner as this is inaccurate. Therefore, EQ-5D is not an abbreviation and is the correct term to use when referring to the instrument in general." Brooks R, Boye KS, Slaap B. EQ-5D: a plea for accurate nomenclature.
