Clinical efficacy (as measured by ulcer area) and safety (as measured by signs of infection) of PRGF and PRGF plus HA in the treatment of pressure ulcers

Effectiveness of platelet-rich plasma and hyaluronic acid for the treatment and care of pressure ulcers.

Article specifications

This clinical trial was published in 2015 in Journal of Biol Res Nurs. (IF 2014:1.427) by Spanish specialists. The aim of the present study was to evaluate the clinical efficacy (as measured by ulcer area) and safety (as measured by signs of infection) of PRGF and PRGF plus HA in the treatment of pressure ulcers (PUs). Patients (N = 100) with 124 Stage II-III PUs were randomized to a control group (n = 25 PUs) for standard care or to case groups for treatment with one (n = 34 PUs) or two (n = 25 PUs) doses of PRGF from their own peripheral blood, or two doses of PRGF plus HA (n = 40 PUs).

 

Results

At 36 days, a significant reduction in ulcer area (p ≤ .001) was observed in all treatment groups, with a mean reduction of more than 48.0% versus baseline. The greatest mean reduction (80.4% vs. baseline) was obtained with the PRGF plus HA regimen. Complete wound healing was observed in 32.0% of PUs treated with two doses of PRGF (p ≤ .002) and in 37.5% of those treated with two doses of PRGF plus HA (p ≤ .004). There were no signs of infection in any PUs during the 36-day follow-up period. The degree of wound healing was inversely correlated with the consumption of drugs such as statins and with the peripheral blood platelet levels of patients at baseline.
