【摘要】 目的 通过检测临床确诊为慢性乙型肝炎患者血清谷丙转氨酶（ALT）、谷草转氨酶（AST）、甲状腺激素T3、T4及促甲状腺素（TSH）含量，进一步探讨慢性乙型肝炎患者肝损情况与甲状腺分泌功能的关系。 方法 收集2009年1-4月79例确诊为慢性乙型肝炎患者（病例组）血清标本，分别检测其ALT、AST、甲状腺激素T3、T4及TSH含量。以同期健康体检者30例作为对照组。比较两组的差异及各指标间的相关性。 结果 病例组AST为（87±113） U/L、ALT为（135±241） U/L、AST/ALT为0.97±0.57、TSH为（1.63±1.29） mU/L、T3为（1.61±0.52）ng/mL、T4为（10.7±2.9） μg/dL，对照组分别为（23±5） U/L、 （18±5） U/L、1.31±0.26、（2.13±0.90） mU/L、（1.19±0.16） ng/mL和（8.6±0.9） μg/dL，两组各指标比较均有统计学差异（Plt;0.01）。所有指标均正常的共有6例（7.6%），有73例（92.4%）存在不同程度的指标异常；在68例AST/ALT比值降低的慢性乙型肝炎患者（93.2%）中，伴有单纯T4升高的有11例（16.2%），单纯T3升高的有4例（5.9%），T3、T4同时升高的有11例（16.2%），T3、T4同时升高且TSH降低的有2例（2.9%），1例T4升高且TSH降低（1.5%），1例仅TSH升高（1.5%）；在4例AST/ALT比值正常的慢性乙型肝炎患者（5.5%）中，有1例T3、T4同时升高且TSH降低，1例T3和T4同时升高，1例单纯T4升高，1例单纯TSH降低；有1例仅AST/ALT比值升高而其他项正常。 结论 慢性乙型肝炎患者除AST/ALT比值异常外，还同时伴有不同程度的甲状腺激素指标异常，其原因可能与慢性乙型肝炎应用干扰素治疗时甲状腺功能受损有关。【Abstract】 Objective To explore the relationship between liver damage and the secretion function of thyroid by detecting the serum alanine aminotransferase (ALT), aspartate aminotransferase(AST), T3, T4, and thyroid stimulating hormone (TSH) in patients with chronic hepatitis B. Methods The serum samples of 79 patients with chronic hepatitis B from January to April 2009 were collected, and the ALT, AST, T3, T4, and TSH concentrations were detected. Another 30 healthy subjects were selected as the control. The detected indexes were compared between the two groups. Results In the case group, the concentration of AST was (87±113)U/L, ALT was (135±241)U/L,AST/ALT was 0.97±0.57, TSH was (1.63±1.29) mU/L, T3 was (1.61±0.52) ng/mL, and T4 was (10.7±2.9) μg/dL; while in the control group, the concentrations of the items were (23±5) U/L, (18±5)U/L, 1.31±0.26, (2.13±0.90) mU/L, (1.19±0.16) ng/mL, and (8.6±0.9) μg/d L, respectively. The differences between the two groups were significant (Plt;0.01). Among the 79 case, 6 (7.6%) had a totally normal result, and 73(92.4%) had an abnormal result. There were 68 patients who had a low ratio of AST/ALT, among whom 11 (16.2%) had a simple T4 elevation, 4(5.9%) had a simple T3 elevation,11(16.2%) had an elevation of both T3 and T4, 2 (2.9%) had an elevation of both T3 and T4 and a depression of TSH, 1(1.5%) had an elevation of T4 and a depression of TSH, and 1 (1.5%) had a simple TSH elevation. There were 4 cases who had a normal ratio of AST/ALT, among whom 1 had an elevation of both T3 and T4 and a depression of TSH, 1 had an elevation of both T3 and T4, 1 had a simple T4 elevation, and 1 had a simple TSH depression. There was 1 case who had only an elevation of AST/ALT. Conclusion Most of the patients with chronic hepatitis B have an abnormal result of thyroid hormone together with the abnormal ratio of AST and ALT. The reason mainly lies in the damage of thyroid function by the usage of interferon for the therapy of chronic hepatitis B.
ObjectiveTo evaluate the relationship between hepatitis B virus (HBV) preS1 antigen and the virus replication index human hepatitis B e antigen (HBeAg) and liver function. MethodsA total of 310 cases of serum samples from patients with chronic HBV treated in our hospital between May and July 2012 were examined and studied. HBV preS1 antigen was detected by ELISA; HBeAg was detected by the Architect i2000 system; and alanine transaminase (ALT) was detected by kinetic method. ResultsThe detection rate of HBV preS1 antigen was higher in HBeAg positive group. HBV preS1 antigen was correlated with HBeAg which was an index of virus replication. HBV preS1 antigen was correlated with ALT levels. ConclusionThe levels of HBV preS1 antigen may reflect the replication of HBV and the reactiveness condition of chronic hepatitis.
ObjectiveTo investigate the significance of carbohydrate antigen 199 (CA199), alanine aminotransferase (ALT), gamma-glutamyl transferase (γ-GT) levels in the diagnosis of liver damage caused by hyperthyroidism. MethodA total of 106 patients confirmed to have hyperthyroid liver damage between February 2012 and February 2014 were selected to form the hyperthyroidism liver injury group (group A). Ninety-five hyperthyroidism patients without liver damage were regarded as the hyperthyroidism without liver injury group (group B). In the same period, 72 healthy subjects were designated to form the control group (group C). Automatic chemiluminescence detector was used to determine free triiodothyronine, free thyroid hormone and CA199, and automatic biochemical analyzer was adopted to measure the levels of γ-GT and ALT. Then we performed the statistical analysis. ResultsThe levels of serum CA199, γ-GT and ALT in group A were significantly higher than those in group B and group C, and the differences were statistically significant (P<0.05). CA199 and γ-GT levels in group B were significantly higher than those in group C (P<0.05). The area under the receiver operating characteristic curve for CA199, γ-GT, ALT was respectively 0.840, 0.895, and 0.818, the maximum Youden indexes were 0.593, 0.703, and 0.578, with the corresponding critical values 37.25 U/mL, 60.81 U/L, and 43.14 U/L, respectively. The parallel dectection of the three indexes improved Youden index to 0.763. ConclusionsCA199, γ-GT and ALT as diagnosis indexes of hyperthyroidism liver damage have good diagnostic value, and combined detection of the three indexes is more favorable for early diagnosis and prediction.
