简要总结
OBJECTIVES: Main objective: To evaluate the effectiveness of plasma rich in growth factors (PRGF) in the treatment of patients with venous ulcers. Secondary objective: To evaluate the safety of plasma rich in growth factors in treating patients with venous ulcers. DESIGN: Randomized, open clinical trial in parallel groups, controlled with conventional treatment.
SAMPLE: Over age patients, of primary care centers of Vitoria, with at least one venous ulcers of 6 or more weeks of evolution and 0.5-6 cm of diameter. INTERVENTION: 1-Experimental group: Autologous PRGF administrated once a week (day 1) + conventional treatment administrated twice a week (days 1 and 4)for 12 weeks of treatment, but in those cases where there has been no complete healing in this period, patients will continue the same management protocol to get it. 2-Control group: Conventional treatment twice a week (days 1 and 4)for 12 weeks of treatment.
Conventional treatment includes: Cleaning and debridement of the wound, the application of corresponding dressing, and using of antibiotic if necessary in each visit.
STATISTICAL ANALYSIS:The primary outcome analysis was done by logistic regression. The crude model and the adjusted model (for confounding variables)will be built. The healing time of ulcers (in days) were analyzed using the Kaplan Meier survival analysis and the corresponding comparison using the log rank test.
详细描述
An open, randomized, of parallel groups, and controlled clinical trial. Patients will be allocated on first come to one of the two treatment groups using a block random sequence generated by computer that will remain hidden from the researchers and patients until allocation.
Experimental group: PRGF together with the corresponding dressing according to annex IV.
Control group: Corresponding dressing according to annex IV.
Both groups will be submitted to a cleaning, debridement, occlusive dressing and use of antibiotic if necessary in each visit.
After signing consent form, and previously of randomization, patients will be submitted to a blood extraction where it will be determinate: Albumine (in g/dl), Hemoglobin (in g/dl), Hematocrit (in %), Creatinine (in mg/dl). If patients have data collected through previous analysis performed until 30 days before, it will not be necessary a new extraction.
