- Abstract
Introduction: Population ageing has led to an increase in the prevalence of many chronic diseases that occur in elderly patients including chronic wounds of various aetiologies, especially leg ulcers. The treatment of these wounds is lengthy and associated with health, economic and social problems. The aim of our study was to compare the outcomes of local injections of autologous growth factors with standard dressings for leg ulcer treatment. Methods: The study included 25 patients with leg ulcers treated with autologous growth factors, and 15 patients treated with standard wet dressings only. The area and depth of ulcers were measured on days 0, 5, 28, 84 and 168, and statistically processed using the chi-square test, the Fischer exact test, the Wilcoxon two-sample test, the non-parametric paired Wilcoxon test and the Friedman analysis of variance (ANOVA) test at a significance level of 5%. Results: Area and depth did not significantly differ between the two groups before initiation of the treatment (p = 0.472 and p = 0.242, respectively). During the study period, the average leg ulcer area decreased in both the study and control groups by 72% and 40%, respectively. The paired Wilcoxon test showed that this decrease was significant in the study group (p < 0.001), but not in the control group (p = 0.075). Conclusion: Leg ulcers heal better when treated with autologous growth factor injections than when treated with standard dressings alone. A further study with a larger number of patients is needed to confirm the presented results. However, this method seems to be a promising way to treat ulcers of the lower extremities.
