Autologous fat grafting in the treatment of a scleroderma stump-skin ulcer: a case report

Autologous Fat Grafting in Hand Surgery: A Systematic Review

Background

Autologous fat grafting (AFG) has gained popularity in both cosmetic and reconstructive surgery, including hand surgery, due to its regenerative potential and dual benefits of enhancing aesthetics and function. This systematic review aims to evaluate the efficacy of AFG in treating various hand pathologies.

Methods

A systematic review was conducted following PRISMA guidelines. PubMed, Cochrane Library, and Embase databases were searched for studies published between January 2001 and October 2022 using the terms "(autologous fat grafting) AND (hand)." Of 224 studies identified, 14 met the inclusion criteria. These studies were analyzed based on study design, pathology treated, type of AFG used, and primary outcomes.

Results

The review included 14 studies: 9 prospective/retrospective studies, 3 case reports, and 2 randomized control trials. Digital ulcers related to systemic sclerosis and hand osteoarthritis were the most frequently treated pathologies. AFG was predominantly used to address symptoms/pain (71.4%), with aesthetics as a secondary benefit in 21.4% of cases. The studies reported improvements in pain, functionality, and patient satisfaction. However, the variability in techniques and outcomes limited the ability to perform a meta-analysis.

Conclusions

AFG shows promise as a minimally invasive treatment option for various hand pathologies, offering both symptomatic relief and aesthetic enhancement. Although initial findings are favorable, further high-quality studies are needed to standardize techniques and confirm long-term efficacy. The versatility and safety profile of AFG suggest it has the potential to become a widely adopted technique in hand surgery.

The importance of body image and aesthetic medicine in systemic sclerosis

Systemic sclerosis is a progressive fibrotic autoimmune disease which mainly affects young women causing fibrosis of the skin and internal organs. In systemic sclerosis patients, facial and hand alterations are significant as these may have an impact on body image. In fact, systemic sclerosis could cause disfigurement of the most visible parts of the body, hindering self-confidence and quality of life. Therefore, the assessment of body image in systemic sclerosis is crucial in order to optimize a tailored care of the patient. In the near future, the creation of a pathway involving dedicated specialists (psychologists, physiotherapists, dermatologists, and plastic surgeons) should become an integral part of the disease management.

Fat transplantation induces dermal adipose regeneration and reverses skin fibrosis through dedifferentiation and redifferentiation of adipocytes

Background

Localized scleroderma causes cosmetic disfigurement, joint contractures, and other functional impairment, but no currently available medications can reverse the resulting skin lesions. Fat grafting is beneficial for reversing skin fibrosis; however, the mechanism by which adipose tissue transplantation contributes to lesion improvement has not been fully clarified. The purpose of our study was to verify the therapeutic effect of fat grafts in reversing skin fibrosis.

Methods

Inguinal fat pads from AdipoqCreER+;mT/mG mice, which were treated with tamoxifen, were transplanted to the skin lesion in bleomycin-treated wild-type C57 mice. Tdtomato transgenic mice-derived adipocytes, adipose-derived stem cells (ASCs), dedifferentiated adipocytes (DAs) were embedded in matrigel and transplanted beneath the skin lesion of bleomycin-treated wild-type C57 mice. A transwell co‐culture system was used to verify the effect of ASCs, adipocytes or DAs on scleroderma fibroblasts or monocytes.

Results

Adipocytes from the fat grafts could undergo dedifferentiation and redifferentiation for dermal adipose tissue re-accumulation within the skin lesion. Moreover, compared with ASCs and adipocytes, DAs show greater potency of inducing adipogenesis. ASCs and DAs showed comparable effect on inducing angiogenesis and suppressing macrophage infiltration in fibrotic skin. Co-culture assay showed that DAs and ASCs were able to reduce fibrosis-related genes in human scleroderma fibroblasts and drive M2 macrophage polarization.

Conclusion

Our results indicated that adipocytes would transform into a more functional and dedifferentiated state and reverse dermal fibrosis, by promoting dermal adipose tissue regeneration, improving angiogenesis, suppressing macrophage-mediated inflammation and myofibroblast accumulation.

Photobiomodulation Therapy: A New Light in the Treatment of Systemic Sclerosis Skin Ulcers

INTRODUCTION

Skin ulcers (SU) represent one of the most frequent manifestations of systemic sclerosis (SSc), occurring in almost 50% of scleroderma patients. SSc-SU are often particularly difficult to treat with conventional systemic and local therapies. In this study, a preliminary evaluation of the role and effectiveness of blue light photobiomodulation (PBM) therapy with EmoLED^® in the treatment of scleroderma skin ulcers (SSc-SU) was performed.

METHODS

We retrospectively analyzed 12 consecutive SSc patients with a total of 15 SU on finger hands. All patients were treated with adequate systemic therapy and local treatment for SU; after a standard skin ulcer bed preparation with debridement of all lesions, EmoLED^® was performed. All patients were locally treated every week during 2 months of follow-up; SU data were collected after 4 weeks (T4) and 8 weeks (T8). Eight SSc patients with comparable SU were also evaluated as controls.

RESULTS

The application of EmoLED^® in addition to debridement apparently produced faster healing of SU. Complete healing of SU was recorded in 41.6% cases during EmoLED^® treatment. Significant improvements in SU area, length, and width, wound bed, and related pain were observed in EmoLED^® patients from T0 to T8. Control subjects treated with standard systemic/local therapies merely showed an amelioration of SU area and width at the end of the follow-up. No procedural or post-procedural adverse events were reported.

CONCLUSIONS

The positive clinical results and the absence of side effects suggest that EmoLED^® could be a promising tool in the management of SSc-SU, with an interesting role to play in the healing process in addition to conventional systemic and local treatments.

Systemic sclerosis cutaneous expression: Management of skin fibrosis and digital ulcers

Systemic sclerosis is a connective tissue disease with cutaneous involvement. Clinical manifestations result from the balance of inflammations/autoimmunity process and fibrogenesis. Patients suffer from skin ulcers, non-ulcerative lesions including digital pitting scars, telangiectasias, subungual hyperkeratosis, abrasions, fissures, and subcutaneous calcinosis. A review about the pathophysiology of the disease, the physical examination of the patients, the instrumental assessment, and possible treatments is performed.
