Abstract:
Objective To investigate the trend of liver function changes in untreated adult patients with Graves’ disease in China, and to analyze the associated factors. Methods Patients with newly diagnosed as well as recurrent Graves’ disease from January 2006 to August 2014 were enrolled. They were over 18 years old and did not receive any treatments, Examination of liver function, thyroid function, and thyroid related antibodies as well as tests regarding virus hepatitis were performed. Results A total of 1 254 patients were enrolled. 33 patients with virus hepatitis were ruled out. Ultimately, 1 221 patients matched the criteria of our trial, with 347 males and 874 females [(39. 3 ± 9. 5) year old]. After inclusion, they were assigned to 2 groups according to their liver function results(605 in normal group and 616 in abnormal group). Compared to normal group, patients in the abnormal group were older [(40. 1 ± 9. 2 vs 38. 5 ± 8. 7) year old, P<0. 05] and with higher proportion of females(81. 8% vs 61. 2% , P<0. 05). Regarding the thyroid function and related antibody tests, some patients yielded results that were extremely high so as to exceed the upper limit of the normal range. These patients were more frequently seen in the group with abnormal liver function. The patients whose thyroid function parameters exceeded the upper limit had higher level of alanine aminotransferase[ALT,(37. 69 ± 7. 51 vs 31. 90 ± 5. 95) U/ L, P<0. 05], aspartate aminotransferase[AST, (31. 97 ± 5. 09 vs 27. 88 ± 3. 82) U/ L, P<0. 05], direct bilirubin[DBiL, (5. 58 ± 0. 77 vs 4. 54 ± 0. 71) μmol/ L, P<0. 05]than the group whose thyroid function on the detected range. In the patients with all results detected, patients in abnormal liver function group had higher level of triiodthyronine[T3 , (5. 42 ± 0. 29 vs 4. 94 ± 0. 33) nmol/ L, P<0. 05], thyroxin[T4 ,(217. 53 ±14. 32 vs 204. 22 ±13. 54) nmol/ L, P<0. 05], free triiodthyronine[FT3 ,(15. 88 ± 2. 86 vs 14. 48 ±4. 83) pmol/ L, P<0. 05], free thyroxin[FT4 ,(48. 91 ±8. 45 vs 42. 95 ±6. 14) pmol/ L, P<0. 05], thyroid peroxidase antibody[ TPOAb, (402. 75 ± 89. 99 vs 210. 70 ± 44. 63) IU/ ml, P < 0. 05] and thyrotrophin receptor antibody[TRAb,(14. 08 ± 5. 24 vs 9. 04 ± 2. 58) IU/ L, P<0. 05]. Multivariate logistic regression analysis revealed that patients’ age(OR=0. 98, 95% CI 0. 97-0. 99), gender(OR=0. 94, 95% CI 0. 91-0. 97), level of FT4 (OR=3. 08, 95% CI 2. 19-4. 32), TPOAb(OR = 0. 98, 95% CI 0. 97-0. 99), and TRAb(OR = 1. 07, 95% CI 1. 01-1. 12) were independent risk factors of their liver dysfunction. Conclusion Graves’ disease may lead to liver dysfunction, which is much more common and severe in elder and female patients, as well as patients who are suffering from hyperthyroidism and raised level of thyroid related antibodies.
