To investigate the relationship between serum sex hormone levels, liver function, and pathogenic mechanisms related to cutaneous lesions involving the facial skin in male patients with liver cirrhosis.
Fifty male cirrhotic patients with facial skin lesions, including spider angiomas, angiotelectasis and special type rash, (mean age: 48.1 +/- 12.2 years) were randomly selected for study and enrolled as the case group. Thirty cirrhotic male patients without facial skin lesions (mean age: 44.5 +/- 11.7 years) were enrolled as the control group. Serum levels of luteinizing hormone (LH), follicular stimulating hormone (FSH), prolactin (PRL), estradiol (E2), progesterone (PRGE), and testosterone (T) were detected and compared between cases and controls by the t-test. All patients were sub-categorized according to severity of cirrhosis (Child-Pugh classification) and comparisons between cases and controls were carried out by single factor analysis of variance. Logistic regression modeling was used to evaluate whether the presence of skin lesions is related to changes in markers of liver impairment, including alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil), serum albumin (Alb), prothrombin time (PT-SEC), creatinine (CREA), platelet count (PLT), and alcoholism.
In the cases with spider veins, LH level was significantly elevated (t = 2.01) and T level was significantly decreased (t = -2.20) (both, P less than 0.05 vs. controls). In the cases with telangiectasia, the LH level (t = 3.76, E2 (t = 2.08) and E2/T ratio (t = 2.98) were significantly elevated and T level was significantly decreased (t = -3.77) (all, P less than 0.05 vs. controls). In the cases with special type rash, FSH level was significantly elevated (t = 2.03) and T level was significantly decreased (t = -2.01) (both, P less than 0.05 vs. controls). In the case group, E2 levels decreased as severity of liver damage increased, while in the control group, E2 levels increased as severity of liver damage increased; however, the difference in average E2 values of the two groups did not reach statistical significance (P more than 0.05). In both cases and controls, the T levels were decreased as the severity of liver damage increased (F = 3.70, P less than 0.05). Multivariate logistic regression analysis showed that increased incidence of facial skin lesions is associated with alcoholism (odds ratio (OR) = 4.46, 95% confidence interval (CI) = 1.45-13.7, P less than 0.05) and elevated serum levels of AST (OR = 11.87, 95% CI = 1.24-113.1, P less than 0.05).
Alcoholism, impaired liver function, and perturbed levels of circulating sex hormones are associated with cirrhosis-related facial lesions and may play important roles in the pathogenesis of cutaneous lesions in patients with cirrhosis.
探讨肝硬化男性患者血清性激素水平、肝功能与面部皮肤病变相关致病机制之间的关系。
随机选取50例有面部皮肤病变(包括蜘蛛痣、血管扩张和特殊类型皮疹)的男性肝硬化患者(平均年龄:48.1±12.2岁)进行研究并纳入病例组。选取30例无面部皮肤病变的男性肝硬化患者(平均年龄:44.5±11.7岁)作为对照组。检测并通过t检验比较病例组和对照组血清促黄体生成素(LH)、促卵泡生成素(FSH)、催乳素(PRL)、雌二醇(E2)、孕酮(PRGE)和睾酮(T)水平。所有患者根据肝硬化严重程度(Child-Pugh分级)进行亚分类,并通过单因素方差分析对病例组和对照组进行比较。采用逻辑回归模型评估皮肤病变的存在是否与肝功能损害指标的变化相关,这些指标包括丙氨酸氨基转移酶(ALT)、天冬氨酸氨基转移酶(AST)、总胆红素(TBil)、血清白蛋白(Alb)、凝血酶原时间(PT-SEC)、肌酐(CREA)、血小板计数(PLT)和酗酒情况。
在有蜘蛛状静脉的病例中,LH水平显著升高(t=2.01),T水平显著降低(t=-2.20)(两者与对照组相比,P均<0.05)。在有血管扩张的病例中,LH水平(t=3.76)、E2(t=2.08)和E2/T比值(t=2.98)显著升高,T水平显著降低(t=-3.77)(所有与对照组相比,P均<0.05)。在有特殊类型皮疹的病例中,FSH水平显著升高(t=2.03),T水平显著降低(t=-2.01)(两者与对照组相比,P均<0.05)。病例组中,随着肝损伤严重程度增加,E2水平降低;而对照组中,随着肝损伤严重程度增加,E2水平升高;然而,两组平均E2值的差异未达到统计学意义(P>0.05)。在病例组和对照组中,随着肝损伤严重程度增加,T水平均降低(F=3.70,P<0.05)。多因素逻辑回归分析显示,面部皮肤病变发生率增加与酗酒(比值比(OR)=4.46,95%置信区间(CI)=1.45-13.7,P<0.05)和血清AST水平升高(OR=11.87,95%CI=1.24-113.1,P<0.05)相关。
酗酒、肝功能受损和循环性激素水平紊乱与肝硬化相关面部病变有关,可能在肝硬化患者皮肤病变的发病机制中起重要作用。
