Autologous Homologous Skin Constructs Allow Safe Closure of Wounds: A Retrospective, Noncontrolled, Multicentered Case Series.

ABSTRACT: An autologous homologous skin construct (AHSC) has been developed for the repair and replacement of skin. It is created from a small, full-thickness harvest of healthy skin, which contains endogenous regenerative populations involved in native skin repair. A multicenter retrospective review of 15 wounds in 15 patients treated with AHSC was performed to evaluate the hypothesis that a single application could result in wound closure in a variety of wound types and that the resulting tissue would resemble native skin. Patients and wounds were selected and managed per provider's discretion with no predefined inclusion, exclusion, or follow-up criteria. Dressings were changed weekly. Graft take and wound closure were documented during follow-up visits and imaged with a digital camera. Wound etiologies included 5 acute and chronic burn, 4 acute traumatic, and 6 chronic wounds. All wounds were closed with a single application of AHSC manufactured from a single tissue harvest. Median wound, harvest, and defect-to-harvest size ratio were 120 cm2 (range, 27-4800 cm2), 14 cm2 (range, 3-20 cm2), and 11:1 (range, 2:1-343:1), respectively. No adverse reactions with the full-thickness harvest site or the AHSC treatment site were reported. Average follow-up was 4 ± 3 months. An AHSC-treated area was biopsied, and a micrograph of the area was developed using immunofluorescent confocal microscopy, which demonstrated mature, full-thickness skin with nascent hair follicles and glands. This early clinical experience with ASHC suggests that it can close different wound types; however, additional studies are needed to verify this statement.

Project description:BackgroundAutologous platelet-rich plasma (PRP) is a treatment that contains fibrin and high concentrations of growth factors with the potential to improve the healing of chronic wounds. This is the first update of a review first published in 2012.ObjectivesTo determine whether autologous PRP promotes the healing of chronic wounds.Search methodsIn June 2015, for this first update, we searched the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library): Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations); Ovid EMBASE; and EBSCO CINAHL. We also searched for ongoing and unpublished clinical trials in the WHO International Clinical Trials Registry Platform (ICTRP) (searched January 2015). We did not impose any restrictions with respect to language, date of publication, or study setting.Selection criteriaWe included randomised controlled trials (RCTs) that compared autologous PRP with placebo or alternative treatments for any type of chronic wound in adults. We did not apply any date or language restrictions.Data collection and analysisWe used standard Cochrane methodology, including two reviewers independently selecting studies for inclusion, extracting data, and assessing risk of bias.Main resultsThe search identified one new RCT, making a total of 10 included RCTs (442 participants, 42% women). The median number of participants per RCT was 29 (range 10 to 117). Four RCTs recruited people with a range of chronic wounds; three RCTs recruited people with venous leg ulcers, and three RCTs considered foot ulcers in people with diabetes. The median length of treatment was 12 weeks (range 8 to 40 weeks).It is unclear whether autologous PRP improves the healing of chronic wounds generally compared with standard treatment (with or without placebo) (risk ratio (RR) 1.19, 95% confidence interval (CI) 0.95 to 1.50; I(2) = 27%, low quality evidence, 8 RCTs, 391 participants). Autologous PRP may increase the healing of foot ulcers in people with diabetes compared with standard care (with or without placebo) (RR 1.22, 95% CI 1.01 to 1.49; I(2) = 0%, low quality evidence, 2 RCTs, 189 participants). It is unclear if autologous PRP affects the healing of venous leg ulcers (RR 1.02, 95% CI 0.81 to 1.27; I(2) = 0% ). It is unclear if there is a difference in the risk of adverse events in people treated with PRP or standard care (RR 1.05, 95% CI 0.29 to 3.88; I(2) = 0%, low quality evidence from 3 trials, 102 participants).Authors' conclusionsPRP may improve the healing of foot ulcers associated with diabetes, but this conclusion is based on low quality evidence from two small RCTs. It is unclear whether PRP influences the healing of other chronic wounds. The overall quality of evidence of autologous PRP for treating chronic wounds is low. There are very few RCTs evaluating PRP, they are underpowered to detect treatment effects, if they exist, and are generally at high or unclear risk of bias. Well designed and adequately powered clinical trials are needed.
