患者,女,31岁。初产,PAPA综合征。病史:多种皮肤病变(坏疽性脓皮病和严重的囊肿性痤疮)和关节炎症(患者3岁时出现)。在15岁时,患者关节炎症进展,关节畸形变得明显。19岁时,患者行左手中指人工关节置换术。但是人工关节受耐甲氧西林金黄色葡萄球菌感染。因而移除人工关节,并进行自体骨移植。20岁时,患者面部痤疮加重。26岁时,患者皮肤病变和关节炎稳定。30岁时,怀疑有自身免疫性疾病。考虑到患者的临床病程,血清IL-1β水平升高(21pg/mL;正常水平<10pg/mL),诊断为PAPA综合征。不过未观察到与家族性PAPA相关的PSTPIP1基因突变,患者家族中没有此类病史。之后,在内科随诊观察PAPA。后来,患者怀孕第7周接入妇产科。患者身高cm,体重56kg(体重指数20.8kg/m2)。最初入院时血压/75mmHg。双手的食指、中指、第三和第四根手指均观察到远端指间关节畸形。患者左脚第二指指间关节僵硬,双下肢和臀部有皮肤色素沉着(图1)。
