RESUMO
Objective To explore the correlation of serum HCV-RNA level with liver function indices and blood routine parameters in patients with hepatitis C,and provide the references for the early diagnosis and monitoring the prognosis of hepatitis C.Methods The study population comprised 651 patients who were diagnosed with hepatitis C in the Second Affiliated Hospital of Medical College of Xi' an Jiaotong University.Serum level of HCV RNA was determined by quantitative realtime polymerase chain reaction (real-time PCR).The data obtained were divided into six groups according to the result of HCV RNA level.Then the correlation of serum HCV-RNA level with liver function indices and blood routine parameters was analyzed.Results With the rising level of serum HCV-RNA,the levels of liver function indices including ALT,AST,AST/ALT,GGT and TBIL were all significant increased in hepatitis C patients.However,A/G presented a declining trend with the increase of serum HCV-RNA level.The lowest value and highest value of ALT,AST,AST/ALT,GGT,TBIL and A/G were 32.3±9.7 U/L and 96.2±13.6 U/L,31.1±8.38 U/L and 113.5±15.9 U/L,0.86±0.09 and 1.19±0.11,29.2± 14.5 U/L and 52.7±16.2 U/L,17.2±4.32 μmol/L and 26.0±5.58 μmol/L,0.98±0.07 and 1.35±0.14,respectively.Significant differences in ALT,AST,AST/ALT,GGT,TBIL and A/G were observed among these groups (F value was 457.1,656.4,149.1,40.18,46.56 and 146.98,respectively.all P＜0.01).Moreover,the levels of blood routine parameters including WBC,NEUT％,RBC,H b and PLT were all significant decreased while that of LY％ was increased with the rising level of serum HCV-RNA in hepatitis C patients.The lowest value and highest value of WBC,NEUT％,LY％,RBC,Hb and PLT were (4.30±0.22) ×109/L and (6.02±0.27) × 109/L,(48.13±3.56)％ and (59.28±3.40)％,(31.05±3.41) ％ and (38.81 ± 4.65)％,(3.73 ± 1.70) × 1012/L and (4.65± 1.88) × 1012/L,(122.01±5.58) g/L and (135.37 ±8.50)g/L,(102.65± 16.87) × 109/L and (148.21 ± 14.40) × 109/L,respectively.There was no significant difference in RBC among groups (F=1.926,all P＜0.05).However,the differences in other blood routine parameters than RBC among groups were statistically significant (F value of WBC,NEUT％,LY％,Hb and PLT was 349.0,132.145,43.65,38.91 and 52.21,respectively.all P＜0.01).Conclusion Serum HCV-RNA level was correlated with routine liver function indices and blood routine parameters.It is important to perform the combined detection of serum HCV-RNA level,routine liver function indices and blood routine parameters in hepatitis C patients,which can help to guide diagnosis and to evaluate the prognosis.
RESUMO
OBJECTIVES: To evaluate the effects of lead on the liver function indices in male lead workers. METHODS: The study comprised of 274 lead workers and 113 non-lead workers who were confirmed not to have HBsAg (Hepatitis B surface Antigen). Blood lead (PbB), blood zinc protoporphyrin (ZPP) and urinary delta-aminolevulinic acid (ALAU) were selected as parameters for monitoring exposure to lead while aspartate aminotransferase (SGOT), alanine aminotransferase (SGPT) and gamma-glutamyltransferase (gamma-GTP) were chosen as parameters for monitoring liver function. Demographic information, such as age, smoking and drinking histories were collected. The duration of work for the lead workers, and their BMI(body mass index), were also obtained. RESULTS: After adjusting for possible confounders {age, BMI, work duration, smoking (pack-year) and drinking (bottles of Soju consumed per week)}, blood lead was observed to be a significant variable from the logistic regression analysis of the abnormalities of SGOT( >35 IU/L), with an odds ratio of 1.04 (95 % CI, 1.008-1.066). The amount of alcohol drunk (odds ratio 1.28: 95 % CI, 1.054-1.549) and BMI (odds ratio 1.24: 95 % CI, 1.075-1.421) were also significant variables. From the multiple linear regression analyses, blood lead was significantly, and positively, associated with SGOT (p<0.05). CONCLUSIONS: These findings suggest that exposure to lead may have an effect on SGOT in male lead workers.
