Data regarding the clinical characteristics of patients with dipeptidyl-peptidase IV inhibitors (DPP4i)-associated BP is inconclusive. We aimed to characterize the clinical features of patients with DPP4i-associated BP, and to assess whether there are phenotypic differences associated with different agents belonging to the DPP4i class. A retrospective prevalence study was performed, including all consecutive patients diagnosed with BP throughout the years 2000 to 2019. The study included 397 patients with BP, of whom 58 (14.6%) were DPP4i-associated. Compared to other patients with BP, patients with DPP4i-associated BP had a more prominent male preponderance (60.3% vs 41.0%; P = .006), presented more frequently with extensive disease (60.3% vs 46.3%; P = .049), had greater truncal (96.6% vs 85.5%; P = .019) and cephalic (51.7% vs 33.6%; P = .008) involvement, and had less frequent peripheral eosinophilia (25.9% vs 51.9%; P < .001). Compared to patients with vildagliptin-associated BP, those with linagliptin-associated BP were managed by higher dosage of systemic corticosteroids in order to achieve disease control (prednisone > 1 mg/kg: 68.2% vs 40.0%; P = .046). In conclusion, DPP4i-associated BP seems to have a unique clinical profile characterized by male predominance, extensive disease, truncal and cephalic involvement, and less peripheral eosinophilia. Linagliptin may be associated with a harder course necessitating more aggressive therapy.
关于二肽基肽酶IV抑制剂(DPP4i)相关血压(BP)患者临床特征的数据尚无定论。我们旨在描述DPP4i相关BP患者的临床特征,并评估属于DPP4i类的不同药物是否存在表型差异。进行了一项回顾性患病率研究,纳入了2000年至2019年期间所有连续诊断为BP的患者。该研究包括397例BP患者,其中58例(14.6%)与DPP4i相关。与其他BP患者相比,DPP4i相关BP患者男性优势更为明显(60.3%对41.0%;P = 0.006),广泛疾病的发生率更高(60.3%对46.3%;P = 0.049),躯干(96.6%对85.5%;P = 0.019)和头部(51.7%对33.6%;P = 0.008)受累更常见,外周嗜酸性粒细胞增多症的发生率更低(25.9%对51.9%;P < 0.001)。与维格列汀相关BP患者相比, 利奈格列汀相关BP患者为实现疾病控制需要更高剂量的全身性皮质类固醇治疗(泼尼松>1 mg/kg:68.2%对40.0%;P = 0.046)。总之,DPP4i相关BP似乎具有独特的临床特征,其特点是男性占主导、疾病广泛、躯干和头部受累以及外周嗜酸性粒细胞增多症较少。利奈格列汀可能与更严峻的病程相关,需要更积极的治疗。
