Comparing the prognostic impact of 131I and/or artificial liver support system on liver function failure combined with hyperthyroidism.

Abstract

Objective: Hyperthyroidism, a prevalent endocrine disorder, can lead to complications such as liver failure due to the liver's essential role in thyroid hormone metabolism. The study aimed to elucidate the respective contributions of 131I and/or ALSS in managing hyperthyroidism alongside liver failure.

Methods: A retrospective analysis was carried out on 74 patients diagnosed with severe liver failure in the context of Graves' disease. Patients were categorized into three groups: group A (n = 34) received 131I treatment, group B (n = 17) underwent 131I and ALSS treatment, and group C (n = 24) received artificial liver support system (ALSS) treatment alone.

Results: Throughout the treatment period, the liver function indexes in all groups exhibited a declining trend. The thyroid function of group A and group B treated with 131I was significantly improved compared to that before treatment. There was no significant change in thyroid function in group C. After the correction of hyperthyroidism, significant improvements were observed in the liver function of individuals in groups A and B, particularly with more noticeable amelioration compared to group C. After two months of treatment, the efficacy rates for the three groups were 79.41%, 82.35%, and 60.87% respectively. Mortality rates of the three groups were 5.88%, 17.65%, and 36% (P < 0.01). Group B, receiving both 131I and ALSS treatments, exhibited a lower mortality rate than group C.

Conclusion: In cases of severe liver failure accompanied by hyperthyroidism, prompt administration of 131I is recommended to alleviate the adverse effects of hyperthyroidism on liver function and facilitate a conducive environment for the recovery of liver functionality.
