The demand for skin tissue allografts to treat burns and other types of injuries increases each year to the extent that categories of donors formerly deemed "unsuitable", such as victims of suicide by polytrauma or poisoning, are now considered. Patients who died by ingestion of/exposure to toxic substances can be accepted as tissue donors after assessment of graft safety to rule out any risks of transferring toxic substances to the recipient. A cadaveric skin donation was obtained from a 57-year-old woman who died from intoxication after ingesting colchicine tablets (0.2 mg/kg). To determine the safety of cadaveric skin allografts, high-performance liquid chromatography-mass spectrometry (LC-MS/MS) was used to identify and quantify colchicine in procured skin. Results revealed that colchicine concentrations were lower than the instrument limit of detection (LOD) of 0.5 ng/mg both in epidermis and dermis. Cell viability assessed through the MTT ([3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide]) test was within standard limits. Thanks to accurate tests performed, which are routinely applied also in clinical diagnostics and forensic toxicology, it was possible to ascertain the safety and suitability of skin tissue for donation.
用于治疗烧伤和其他类型损伤的同种异体皮肤移植的需求逐年增加,以至于现在开始考虑以前被认为“不合适”的供体类别,比如多发伤或中毒自杀的受害者。因摄入/接触有毒物质而死亡的患者,在评估移植物安全性以排除将有毒物质转移给接受者的任何风险后,可被接受为组织供体。从一名因服用秋水仙碱片(0.2毫克/千克)中毒死亡的57岁女性身上获取了尸体皮肤捐赠。为了确定尸体皮肤移植的安全性,采用高效液相色谱-质谱联用仪(LC-MS/MS)来识别和定量所获取皮肤中的秋水仙碱。结果显示,表皮和真皮中的秋水仙碱浓度均低于仪器检测限(LOD)0.5纳克/毫克。通过MTT([3-(4,5-二甲基噻唑-2-基)-2,5-二苯基四氮唑溴盐])试验评估的细胞活力在标准范围内。由于进行了准确的检测,这些检测在临床诊断和法医毒理学中也常规应用,所以能够确定皮肤组织捐赠的安全性和适用性。
