Abstract
PURPOSE: Therapeutic plasma exchange (TPE) is a treatment option to reduce thyroid hormones in the event of contraindication or unresponsiveness to antithyroid drugs (ATDs). METHODS: We analyzed 11 patients with hyperthyroidism who received TPE prior to surgery between January 2008 and December 2016 at our center. RESULTS: In total, 41 processes were applied to 11 patients with hyperthyroidism. The median age was 40 years, and 90.9% of the patients were female. Seven patients had Graves' disease, while four had a toxic multinodular goiter. The distribution of TPE indications comprised contraindication to ATDs (64%) and insufficient response to ATDs (36%). An adequate response was not obtained with TPE in two patients, and cholestyramine plus methimazole and Lugol solution were applied. The median number of TPE sessions was 3. During the TPE period, a β-blocker was applied concurrently except in one patient who was contraindicated for the drug. The reduction in FT3 and FT4 hormones and the increase in TSH levels were statistically significant after TPE application (p values of 0.003, 0.033 and 0.008, respectively). Regarding adverse events of TPE application, an allergic reaction was seen in one patient, while prolongation of prothrombin time without any clinical findings was seen in another patient. Ten patients underwent total thyroidectomy, and one patient underwent a gynecological surgery procedure without any major complications. CONCLUSION: The American Society for Apheresis guideline, which is the most referenced guideline, mentions the utilization of TPE before thyroid surgery, only in patients with thyrotoxicosis despite the wider necessity of this treatment choice under the condition of uncontrolled hyperthyroidism prior to any kind of surgery. We concluded that TPE is a reliable and effective application in patients with hyperthyroidism before any surgical procedure, according to our study results.
