UNASSIGNED: The primary characteristic of ankylosing spondylitis (AS) involves inflammation occurring within the sacroiliac joint and the spine, leading to destruction and eventual ankylosis. A notably infrequent complication associated with AS is vasculitis, with limited reports linking AS to vasculitis. This case study documents a 48-year-old male, diagnosed with HLA-B27-positive AS for the past 15 years, who developed abdominal pain and skin lesions following the cessation of his medication on his own. Subsequent clinical evaluations identified leukocytoclastic vasculitis (LCV) related to AS after excluding all other potential causes of LCV, including drug-related sources, cancer, hepatitis B and C viruses, Henoch-Schönlein purpura (HSP), and IgA nephropathy.
■强直性脊柱炎(AS)的主要特征涉及发生在骶髂关节和脊柱内的炎症,导致破坏和最终的强直。与AS相关的罕见并发症是血管炎,有限的报告将AS与血管炎联系起来。这个案例研究记录了一名48岁的男性,在过去的15年中被诊断为HLA-B27阳性AS,他停止服药后出现腹痛和皮肤损伤。随后的临床评估确定了与AS相关的白细胞碎裂性血管炎(LCV),排除了LCV的所有其他潜在原因。包括与毒品有关的来源,癌症,乙型肝炎和丙型肝炎病毒,过敏性紫癜(HSP),IgA肾病。
