Abstract

OBJECTIVE

The aim was to investigate the pathogenesis of telangiectatic matting (TM) and identify possible risk factors.

METHODS

This study had two parts. The clinical records of consecutive patients were retrospectively analysed to identify risk factors for TM. In the second part, the haemostatic and coagulation profile of the subset of patients with TM were analysed and compared with controls using standard coagulation tests, platelet function and a global assay of coagulation (rotational thromboelastometry, ROTEM).

RESULTS

In 352 consecutive patients presenting to a phlebology practice, 25 patients had TM (7.1%). All 25 patients were female with the median age of 45 (27-57) years. A comprehensive medical history was taken. Among 27 possible risk factors assessed, statistically significant associations included recurrent epistaxis, easy bruising, hypersensitivity (eczema, hives, hay fever, and rhinitis), previous treatment with sclerotherapy or endovenous laser for lower limb veins, and a family history of telangiectasias. Variables not associated with TM included oral contraceptive intake, hormone replacement therapy, and age. The haemostatic and coagulation profile of 12 patients (6 male and 6 female) with TM did not differ significantly from those without TM.

CONCLUSION

TM is associated with both hypersensitivity and a bleeding tendency. This study revealed no significant increase in the incidence of haemostatic abnormalities in patients with TM compared with the control group. Given the significant association with hypersensitivity disorders, the underlying mast cell hyper-reactivity may contribute to both hypersensitivity and a bleeding tendency and predispose patients to TM.

摘要

目的

研究毛细血管扩张性苔藓(TM)的发病机制并确定可能的危险因素。

方法

本研究分为两部分。回顾性分析连续患者的临床记录,以确定 TM 的危险因素。在第二部分中,使用标准凝血试验、血小板功能和凝血的全局检测(旋转血栓弹性测定法,ROTEM)分析和比较 TM 亚组患者的止血和凝血特征与对照组。

结果

在 352 例连续就诊于静脉疾病专科的患者中,有 25 例患者发生 TM(7.1%)。25 例患者均为女性,中位年龄为 45(27-57)岁。详细询问了全面的病史。在评估的 27 个可能危险因素中,有统计学意义的关联包括复发性鼻出血、容易瘀伤、过敏(湿疹、荨麻疹、花粉症和鼻炎)、先前下肢静脉硬化治疗或静脉内激光治疗、以及家族性毛细血管扩张症。与 TM 无关的变量包括口服避孕药的使用、激素替代疗法和年龄。12 例 TM 患者(6 例男性和 6 例女性)的止血和凝血特征与无 TM 患者无显著差异。

结论

TM 与过敏和出血倾向有关。与对照组相比,本研究未发现 TM 患者止血异常的发生率显著增加。鉴于与过敏疾病的显著关联,基础肥大细胞过度反应可能导致过敏和出血倾向,并使患者易患 TM。
