Italian recommendations on enzymatic debridement in burn surgery.

INTRODUCTION: Nexobrid®, a bromelain-based type of enzymatic debridement, has become more prevalent in recent years. We present the recommendations on enzymatic debridement (Nexobrid®)'s role based on the practice knowledge of expert Italian users. METHODS: The Italian recommendations, endorsed by SIUST (Italian Society of Burn Surgery), on using enzymatic debridement to remove eschars for burn treatment were defined. The definition followed a process to evaluate the level of agreement (a measure of consensus) among selected experts, representing Italian burn centers, concerning defined clinical aspects of enzymatic debridement. The consensus involved a multi-phase process based on the Delphi method. RESULTS: The consensus panel included experts from Italy with a combined experience of 1068 burn patients treated with enzymatic debridement. At the end of round 3 of the Delphi method, the panel reached 100% consensus on 26 out of 27 statements. The panel achieved full, strong consensus (all respondents strongly agreed on the statement) on 24 out of 27 statements. DISCUSSION: The statements provided by the Italian consensus panel represent a "ready to use" set of recommendations for enzymatic debridement in burn surgery that both draw from and complete the existing scientific literature on the topic. These recommendations are specific to the Italian experience and are neither static nor definitive. As such, they will be updated periodically as further quality evidence becomes available.

Plasmapheresis, Intravenous Immunoglobulins, and Autologous Serum Eyedrops in the Acute Eye Complications of Toxic Epidermal Necrolysis.

PURPOSE: Toxic epidermal necrolysis (TEN) is a rare, life-threatening, drug-induced, mucocutaneous disease, which can severely affect the ocular surface. The purpose of this study was to investigate the efficacy of plasmapheresis, human IV immunoglobulins (IVIg), and autologous serum (AS) eyedrops in the treatment of the severe acute ocular complications of TEN. METHODS: A retrospective chart review of all patients admitted to the Burn Unit, Azienda Ospedaliero-Universitaria-Sassari, Sassari, Italy, from 2009 to 2015, identified 9 patients (2 men, 7 women; mean age 63.8 ± 24.7 years) with TEN. Bilateral, acute ocular surface complications were observed in 7 (78%) patients; 3 showed catarrhal conjunctivitis, whereas 4 had severe pseudomembranous conjunctivitis and corneal ulcers. RESULTS: All patients with TEN were immediately treated with plasmapheresis and human IVIg, which produced a marked improvement in the patients' general condition. In the 3 with catarrhal conjunctivitis, preservative-free artificial tears and topical antibiotics were beneficial. In the 4 with severe pseudomembranous conjunctivitis and corneal ulcers, treatment with AS eyedrops resulted in corneal and conjunctival epithelium healing over 3-6 weeks. After a minimum follow-up of at least 12 months, there were minimal/mild residual signs and symptoms of dry eye. CONCLUSIONS: Plasmapheresis and IVIg may be life-saving and contribute to reduce ocular surface inflammation in TEN. Autologous serum eyedrops, prepared after plasmapheresis completion and IVIg infusion, may be helpful in the management of the severe acute ocular complications of TEN.

[Lyell's syndrome: proposal for a therapeutic protocol]. / Sindrome di Lyell: proposta di un protocollo terapeutico.

Toxic epidermal necrolysis or Lyell's syndrome is a life-threatening, drug-induced disorder characterized by severe epidermal injury. Although plasmapheresis is expensive and requires easy venous access, it could be included in the first-line treatment of toxic epidermal necrolysis. The method is safe and effective, providing prompt relief from pain and rapid cessation of necrolysis. Moreover, in our experience plasmapheresis could be used in patients who were unresponsive to corticosteroids, and in patients with severe clinical symptoms.
