Abstract
BACKGROUND: Current standard management of diabetic foot ulcers (DFUs) consists of surgical debridement followed by soak NaCl 0.9% gauzes tight infection and glycaemic control. Nowadays the use of advanced platelet-rich fibrin (A-PRF) has emerged as an adjunctive method for treating DFUs. This study was conducted to demonstrate the ability of combine A-PRF + HA as a complementary therapy in DFUs healing related with angiogenesis,inflammation and granulation index process. METHODS: were included in the study. The number of subjects was calculated based on the rule of thumb and allocated randomly into three groups, namely topical A-PRF + HA, A-PRF and Sodium Chloride 0.9% as a control, for each of 10 subjects. A-PRF made by 10 mL venous blood, centrifuge 200 G in 10 min, meanwhile A-PRF + HA though mix both them with vertex machine around 5 min. Biomarker such as VEGF, PDGF and IL-6 examined from DFU taken by cotton swab and analysis using ELISA. Granulation Index was measured using ImageJ. Biomarkers and granulation index were evaluated on day 0, 3, 7 and 14. Data were analysed using SPSS version 20 with Anova and Kruskal Wallis test to compare the angiogenesis and inflammation effect between the three groups. RESULT: In topical dressing A-PRF + HA, there is an increase in delta VEGF on day-3 (43.1 pg/mg protein) and day-7 (275,8 pg/mg protein) compared to A-PRF on day-3 (1.8 pg/mg protein) and day-7 (104.7 pg/mg protein), also NaCl (control) on day-3 (-4.9 pg/mg protein) and day-7 (28.3 pg/mg protein). So that the delta VEGF of A-PRF + HA group increase significantly compared with others on day-3 (p = 0.003) and day- 7 (p < 0.001). Meanwhile A-PRF + AH group, there is also a decrease in delta IL-6 after therapy on day-3 (-10.9 pg/mg protein) and day-7 (-18.3 pg/mg protein) compared to A-PRF in delta IL-6 on day- 3 (-3.7 pg/mg protein) and on day-7 (-7.8 pg/mg protein). In NaCl (control) group there is a increase delta IL-6 on day-3 (4.3 pg/mg protein) and on day-7 (35.5 pg/mg protein). So that the delta IL-6 of A-PRF + HA group decrease significantly compared with others only on day- 7 (p = 0.015). In PDGF le level analysis, A-PRF + HA group increase significantly (p = 0.012) only in day -7 compare with other group (5.5 pg/mg protein). CONCLUSION: The study shows the superior role of combined A-PRF + HA in the treatment DFU though increase angiogenesis and decrease inflammation pathway. The advantage of using A-PRF + HA is that it accelerates wound healing by increasing granulation tissue compared to A-PRF alone.
