Serum Iodine Is Increased in Subjects Having Budd-Chiari Syndrome.

This study was performed to investigate the status of serum iodine concentration among the Budd-Chiari syndrome (BCS) patients and its effect on thyroid hormone. The study group serum specimens were collected from 233 BCS patients and 60 healthy people. Serum iodine was analyzed with the Sandell-Kolthoff method, and the ELISA method was used to detect thyroid function: TSH, T3, T4, FT3, and FT4. The serum iodine level of patients with BCS was 316.7 ± 256.8 µg/L, greatly higher than 76.3 ± 25.7 µg/L of serum iodine for control group (p < 0.001), but with no significant difference among different types of BCS. There were no statistically significant differences in thyroid hormone levels (TSH, T3, T4, FT3, and FT4) between people with BCS and control group, although the TSH level of BCS group is slightly higher than that of normal control group. This study demonstrates that iodine may be related to the pathogenesis of BCS and needs to be paid more attention.
