Background: Trophic ulcers secondary to leprosy pose a great stigma to patients and remain a challenge to the treating dermatologists. Platelet-rich plasma (PRP) introduces growth factors directly into the wound and aids in rapid healing. The role of PRP in the treatment of trophic ulcers in leprosy patients has not yet been established by randomized controlled trials. Aims: To study the effectiveness and safety of autologous PRP therapy with total contact casting versus total contact casting alone in the treatment of trophic ulcers in leprosy. Methods: In an observer-blind, randomized (1:1) controlled study, 118 patients were enrolled. PRP was prepared by the manual double-spin method (1600 rpm for 10 min followed by 4000 rpm for 10 min). After wound bed preparation, activated PRP was injected intra- and perilesionally, and platelet-poor plasma gel was applied over the ulcer bed. Occlusive dressings and total contact casting were then applied in Group A, and only total contact casting was applied in Group B. The same procedure was repeated every 2 weeks for 8 weeks. Results: In all, 56 patients were analyzable in Group A and 52 in Group B. The surface area of the ulcer decreased significantly from first follow-up onward in both the groups (P < 0.001 in both the groups). Intergroup comparison showed that the reduction in the surface area of the ulcer was significantly more in Group A than in Group B from the first follow-up onward (P = 0.038) and the difference was maintained till the fifth follow-up (P < 0.001). At the end of the study, 91.10 ± 9.65% ulcer surface area reduction had occurred in Group A, whereas it was 79.77 ± 17.91% in Group B (P < 0.001). Trophic ulcers healed completely more often in paucibacillary leprosy patients (P < 0.001) and in those with a lower initial surface area of the ulcer (P < 0.001). Limitation: Short duration of treatment (8 weeks). Conclusion: PRP combined with total contact casting accelerates the healing of trophic ulcers of leprosy and is more effective than total contact casting alone. Complete remission is more likely to occur when the duration and surface area of ulcer are less and in the paucibacillary spectrum.
