RESUMO
INTRODUCTION: Haemophilic synovitis is caused by chronic accumulation of blood in the joint. Conservative treatment is insufficient to solve this pathology. Platelet-rich plasma (PRP) has a high concentration of growth factors (GFs) that play a key role in regulation and stimulation of healing processes. The aim of this study was to describe the effect of PRP injection in chronic synovitis of the joints in patients with haemophilia (PWH). PATIENTS AND METHODS: Nineteen patients with 28 joints were treated at our centre in Buenos Aires, Argentina between December 2014 and December 2015. Eighteen were Haemophilia type A (17 severe, one mild) and one was type B severe. Mean age was 26 years old. Chronic synovitis was present in two ankles, seven elbows and 19 knee joints. All affected joints were evaluated for range of motion (ROM), perimeter, Haemophilia Joint Health Score (HJHS), number of bleedings episodes and Visual Analogue Scale (VAS). Evaluations were before treatment and 3 and 6 months after treatment. RESULTS: A mean volume of 4 mL of PRP was injected into the joint cavity. The statistical analysis before and after treatments revealed a statistically significant (P < 0.001) decrease in the HJHS score. Decrease in joint bleeding episodes was also statistically significant (P < 0.001). All patients reported pain relief and VAS scores were statistically significant (P < 0.001). Joint perimeter also showed a statistically significant difference (P < 0.001). No complications were observed in any of the patients, either during blood collection or during PRP injection, even for inhibitor patients. CONCLUSION: Platelet-rich plasma is a useful, safe, and inexpensive treatment for chronic haemophilic synovitis.

INTRODUCTION: Wound healing is an intricate process whereby the skin repairs itself after injury according to a specific sequence: haemostasis, inflammation, proliferation and remodelling. Cell therapy has the potential to improve wound healing conditions and can be applied in both acute and chronic wounds. Normal healing requires adequate haemostatic function. Patients with coagulation disorders whose haemostatic function is altered may not heal naturally. AIM: The aim of this study was to show a simple, safe and inexpensive minimally invasive technique for wound repair in patients with coagulation disorders which involves the use of concentrated autologous adipose cells. PATIENTS AND METHOD: Six patients were enrolled in this study at the Foundation of Haemophilia, in Buenos Aires, Argentina. Five patients had severe haemophilia type A and one had severe von Willebrand diseases. The average age was 37.5 years old. One patient had a retractile scar (RS) and five patients had cutaneous fistulas (CF). Suction was used to obtain autologous adipose graft from subcutaneous abdominal tissue. The graft was centrifuged and, the adipose cell concentrate was transferred to a syringe and injected in the edge of the lesion. RESULTS: One adipose suction in each patient was performed. There were no intraoperative or postoperative complications in any of the six patients. CONCLUSIONS: The application of autologous adipose graft is a simple and safe treatment for complicated wound repair in patients with coagulation disorders.
RESUMO
Development of inhibitors against factor VIII (FVIII) or FIX is the most serious complication of replacement therapy in patients with haemophilia. Haemophilic pseudotumours in a patient with inhibitors can lead to devastating consequences. The aim of this study is to show our experience in the treatment of 10 pseudotumours in 7 patients with inhibitors who were treated by the same multidisciplinary team in the period between January 2000 and March 2013. Seven severe haemophilia A patients were treated at the Haemophilia Foundation in Buenos Aires, Argentina, for 10 pseudotumours. Eight were bone pseudotumours and two soft tissue. All patients underwent imaging studies at baseline to assess the size and content of the lesion. The patients received Buenos Aires protocol as conservative treatment of their pseudotumours for 6 weeks, after which they were evaluated. Only one patient responded to conservative treatment. Surgery was performed on the others six patients, since their pseudotumours did not shrink to less than half their original size. Any bleeding in the musculoskeletal system must be treated promptly in order to prevent pseudotumours. When pseudotumours do appear in inhibitor patients, they can be surgically removed when patients received proper haemostatic coverage, improving the quality of life of these patients.
