坏疽性脓皮病的临床特征和治疗情况分析

Analysis of clinical features and treatment of pyoderma gangrenosum

目的探讨坏疽性脓皮病(PG)的临床特征和治疗情况。方法采用回顾性观察性研究方法。2012年1月—2021年7月,北京阜诚医院收治25例符合入选标准的PG患者,其中男16例、女9例,发病年龄14~75岁,PG分型为溃疡型者17例、脓疱型者6例、增殖型者1例、大疱型者1例,6例患者合并系统性疾病、19例患者未合并系统性疾病。应用糖皮质激素等进行系统治疗的同时,行创面换药或手术植皮处理。统计患者实验室检查及组织病理学检查结果,总体疗效及随访情况,创面分泌物标本微生物培养结果阳性和阴性患者的创面愈合时间,合并和未合并系统性疾病患者的疗效。结果19例患者血常规检查结果出现异常,全部患者各项免疫学指标均未见异常;14例患者创面分泌物标本微生物培养结果为阳性;15例创面进展快的患者溃疡边界组织病理学检查结果主要为局部组织炎症改变。17例患者创面治愈、7例患者创面大部分愈合、1例患者创面未愈合。经1年随访,3例患者因出院后自行停药导致PG复发,后调整用药后创面逐渐愈合;其余患者未复发。14例创面分泌物标本微生物培养结果阳性患者创面愈合天数为21~55 d,11例创面分泌物标本微生物培养结果阴性患者创面愈合天数为20~54 d。6例合并系统性疾病患者中3例患者创面治愈、3例患者创面大部分愈合,19例未合并系统性疾病患者中14例患者创面治愈、4例患者创面大部分愈合、1例患者创面未愈合。结论PG患者的实验室检查和病理表现无特征性、临床表现丰富多样,因而易被误诊。应用糖皮质激素加免疫抑制剂治疗PG的效果较好,对其创面可进行外科干预,具体为急性期不建议过度清创、收缩期可植皮。

Objective To explore the clinical features and treatment of pyoderma gangrenosum(PG).Methods A retrospective observational study was conducted.From January 2012 to July 2021,25 patients with PG who met the inclusion criteria were admitted to Beijing Fucheng Hospital,including 16 males and 9 females,with the age of onset of disease being 14 to 75 years.Among them,the classification of PG identified 17 cases of ulcerative type,6 cases of pustular type,1 case of proliferative type,and 1 case of bullous type.Six patients were accompanied with systemic diseases,while 19 patients were not accompanied with systemic diseases.At the same time of systemic treatment with glucocorticoids,dressing changes or surgical skin grafting was performed on the wounds.The results of laboratory and histopathological examinations,the overall curative effects and follow-up of patients,the wound healing time of patients with negative and positive microbial culture results of wound secretion specimens,and the curative effects of patients with and without systemic diseases were analyzed.Results The results of blood routine examination of 19 patients were abnormal,and all the immunological indexes were normal in all the patients;the microbial culture results of wound secretion specimens were positive in 14 patients;and the histopathological examination results of ulcer boundary tissue in 15 patients with rapid wound progress were mainly local tissue inflammatory changes.The wounds were cured in 17 patients,mostly healed in 7 patients,and not healed in 1 patient.After one-year's follow-up,the PG in 3 patients relapsed due to self-discontinuation of medication after discharge,and the wounds were healed gradually after adjustment of medication,while the remaining patients had no relapse.The days of wound healing in 14 patients with positive microbial culture results of wound secretion specimens were 21-55 days,and the days of wound healing in 11 patients with negative microbial culture results in wound secretion specimens were 20-54 days.In the 6 patients with systemic diseases,the wounds of 3 patients were cured,and the wounds of the other 3 patients were mostly healed.In the 19 patients without systemic diseases,the wounds of 14 patients were cured,the wounds of 4 patients were mostly healed,and the wound of 1 patient was not healed.Conclusions The laboratory examination and pathological manifestations of patients with PG lacks characteristics,and their clinical manifestations are rich and diverse,thus PG can be easily misdiagnosed.The glucocorticoids combined with immunosuppressive therapy have good effects on PG.Surgical intervention can be performed on the wounds.Specifically,excessive debridement is not recommended in the acute phase,but skin grafting can be performed in the contraction phase.
