An association between essential mixed cryoglobulinemia and hepatitis C virus (HCV) infection has been reported. Dermatologic manifestations are a classic presenting complaint in essential mixed cryoglobulinemia. The aim of this study was to compare the frequency and the nature of dermatologic manifestations in essential mixed cryoglobulinemia according to the presence of anti-HCV antibodies. Sixty-two consecutive patients with essential mixed cryoglobulinemia were tested for anti-HCV antibodies. Dermatologic manifestations were systematically assessed.
Anti-HCV antibodies were detected in 35 patients. Palpable purpura corresponding histologically to leukocytoclastic vasculitis was the more frequently observed dermatologic manifestation and occurred mainly in HCV-antibody-positive patients. The patients with purpura had significantly higher serum cryoglobulin levels than patients without purpura.
The frequency of palpable purpura is higher in HCV-antibody-positive patients and is related to the serum cryoglobulin levels.
已有报道称特发性混合型冷球蛋白血症与丙型肝炎病毒(HCV)感染之间存在关联。皮肤表现是特发性混合型冷球蛋白血症的典型主诉。本研究的目的是根据抗HCV抗体的存在情况,比较特发性混合型冷球蛋白血症中皮肤表现的频率和性质。对62例连续性特发性混合型冷球蛋白血症患者进行了抗HCV抗体检测,并系统评估了皮肤表现。
35例患者检测出抗HCV抗体。组织学上符合白细胞破碎性血管炎的可触及性紫癜是最常观察到的皮肤表现,主要发生在抗HCV抗体阳性患者中。有紫癜的患者血清冷球蛋白水平明显高于无紫癜的患者。
抗HCV抗体阳性患者中可触及性紫癜的发生率较高,且与血清冷球蛋白水平有关。
