Chronic ulcers can benefit from topical treatment with growth factors (GFs). PLT gel provides tissue regeneration-inducing GFs. The aim of this study was to verify the effectiveness of autologous PLT gel in the treatment of nonhealing skin lesions.
PLT gel was produced by treating PLTs with autologous thrombin. Two groups of patients were investigated: patients with dehiscent sternal wounds and patients with necrotic skin ulcers. Patients treated with PLT gel were retrospectively compared with patients having similar lesions but undergoing conventional treatment. The clinical endpoints of the study were the healing rate, the length of hospital stay, and/or the time required to bring about adequate tissue regeneration in order to undergo reconstructive plastic surgery.
In patients with treated dehiscent sternal wounds the healing rate (3.5 vs. 6.0 wks, p = 0.0002) and hospital stay (31.5 vs. 52.5 days, p < 0.0001) were significantly reduced. Patients with treated necrotic skin ulcers required a notably shorter time to have surgery (median 15.0 vs. 35.5 wks, p < 0.0001). Neither adverse reactions nor in-situ recurrences were observed.
Patients with chronic unhealing wounds showed substantial improvement when treated with PLT gel lesion dressings.
慢性溃疡可受益于生长因子(GFs)的局部治疗。血小板凝胶可提供诱导组织再生的生长因子。本研究的目的是验证自体血小板凝胶在治疗不愈合皮肤损伤中的有效性。
通过用自体凝血酶处理血小板来制备血小板凝胶。对两组患者进行了研究:胸骨裂开伤口患者和坏死性皮肤溃疡患者。将接受血小板凝胶治疗的患者与患有相似损伤但接受传统治疗的患者进行回顾性比较。该研究的临床终点是愈合率、住院时间和/或实现充分组织再生以进行整形重建手术所需的时间。
在接受治疗的胸骨裂开伤口患者中,愈合率(3.5周对6.0周,p = 0.0002)和住院时间(31.5天对52.5天,p < 0.0001)显著缩短。接受治疗的坏死性皮肤溃疡患者进行手术所需的时间明显缩短(中位数15.0周对35.5周,p < 0.0001)。未观察到不良反应或原位复发。
慢性不愈合伤口患者使用血小板凝胶伤口敷料治疗后有显著改善。
