About this study
Hemophilia is a recessive X chromosome linked genetic disorder of blood coagulation that affects about one in every ten thousand people. Hemarthrosis, which you can begin in childhood, promptly leads to degenerative changes of the articular cartilage which culminate in deformity and degenerative changes early, known as hemophilic arthropathy, which is the most common complication of hemophilia. Aside administration of clotting factor, treatment should address the degenerative changes already present in patients joints. Our objective is to evaluate the effectiveness of articular washing followed by infiltration with corticosteroids and hylan G-F 20, followed by a program of home exercises and/or academy as the previous level of hemophilia patients, in relation to pain relief, and improved function and quality of life.
Read the detailed description
Hemophilia is a recessive X chromosome linked genetic disorder of blood coagulation that affects about one in every ten thousand people. There are two main types of hemophilia. Hemophilia A or classical hemophilia corresponds to 80% of the cases, and is caused by a deficiency or change of factor VIII. Hemophilia B is caused by deficiency or amendment of factor IX, and represents about 20%. Patients with hemophilia type A or B have the same clinical presentation. Cases with moderate or severe hemophilia exhibit a tendency to spontaneous bleeding or after minimal trauma, being the joints the most frequent sites of hemorrhage. The joints most commonly affected are the knees, followed by the elbows, ankles, shoulders and hips. Hemarthrosis, which you can begin in childhood, promptly leads to degenerative changes of the articular cartilage which culminate in deformity and degenerative changes early, known as hemophilic arthropathy, which is the most common complication of hemophilia. The hemophilic arthropathy is highly debilitating and consumes a large amount of resources for the treatment of hemophilic patients. Currently, by the adequate administration of the clotting factor, the hemophilic patient has a life expectancy of next to normal. Therefore other forms of treatment must be researched; they can be palliative or modifiers of the natural history of disease, to try to postpone the need for arthroplasty . Our objective is to evaluate the effectiveness of treatment, consisting of articular washing followed by infiltration with corticosteroids and hylan G-F 20, followed by a program of home exercises and/or academy as the previous level of hemophilia patients, in relation to pain relief, and improved function and quality of life.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Joint lavage and viscosupplementationProcedure or surgery
Also called intra-articular injection
The joint will be washed until obtaining translucent liquid and not hemorrhagic. Then it will receive an intra-articular injection of 6ml of hyaluronic acid (Synvisc One), 1ml of triamcinolone and 2 ml of ropivacaine.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Joint lavage and viscosupplementation in people with Osteoarthritis and Hemarthrosis, run by University of Sao Paulo General Hospital at 1 site in Brazil.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 10 Sep 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
WOMAC (time frame: 12 months). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Sep 2013.
