Item PREOPERATIVE THERAPEUTIC PLASMA EXCHANGE AND SURGICAL TREATMENT IN THYROTOXICOSIS PATIENTS: A SINGLE-CENTRE RETROSPECTIVE COHORT STUDY(2021) Yabanoglu, H.; Sari, R.; Haydardedeoglu, F. Eksi; Kus, M.; Hargura, A.S.; Arer, I.M.; 0000-0003-3492-9953; 35342473Context. Therapeutic plasma exchange (TPE) provides time for thyroidectomy in thyrotoxic patients. Objective. TPE is indicated in cases where antithyroid medications cannot be used due to the side effects or attain no adequate hormonal suppression response at the highest dosage and in cases of rapid onset of clinical symptoms. This study presents the treatment results of patients who underwent TPE and were subsequently operated for thyrotoxicosis. Design. The patients who underwent thyroidectomy and TPE between January 1999 and February 2019 were retrospectively analyzed. Subjects and Methods. The files of 27 patients with thyrotoxicosis who performed TPE prior to surgery were analyzed in relation to the demographic and clinical features. Results. We included 15 (55.6%) females, 12 (44.4%) males with a mean age of 44 (23-82) years. The pre-TPE mean free thyroxine (fT4) level was 12 (5-46) pmol/L while free tri-iodothyronine (fT3) level was 34 (17-141) pmol/L. The post-TPE fT4 level was 6 (3-10) pmol/L while the fT3 level was 21 (12-41). There was one case of an allergic reaction during the procedure. In the postoperative follow-up, there was transient hypocalcemia in 8 (29%) patients, permanent hypocalcemia in 1 (3.7%) patient, and surgical site infection in 1 (3.7%) patient. Conclusion. Preoperative TPE is an alternative treatment option for thyrotoxic patients. This is an especially effective treatment for patients with inadequate response or adverse reaction to antithyroid drugs or patients who need urgent surgery for thyroid storm.Item Mean platelet volume in Graves' disease: A sign of hypermetabolism rather than autoimmunity?(2017) Bagir, Gulay Simsek; Haydardedeoglu, Filiz Eksi; Bakiner, Okan Sefa; Bozkirli, Emre; Ertorer, Melek Eda; 0000-0002-1644-6790; 0000-0002-0179-9673; 0000-0001-7357-8709; 29067056; AAK-5525-2021; E-9887-2014; AAK-5003-2021; ABI-3705-2020Objective: To evaluate the impact of mean platelet volume (MPV) on predicting disease course among patients with Graves' disease (GD). Methods: This retrospective study was performed between 2013-2016 at the Outpatient Endocrinology Clinic of Baskent University Faculty of Medicine, Adana hospital on 65 patients with GD. Among participants, 30 cases experienced thyrotoxicosis again during the first six months after discontinuing anti-thyroid drug (ATD) sessions that had been carried out for at least 12 months prior to stopping (Relapse group). We also observed 35 patients who exhibited normal thyroid functions within six months following ATD withdrawal (Remission group). MPV levels and thyroid function tests were recorded and total duration of ATD therapy was calculated for all participants. Results: The mean MPV level that was measured at the time of drug withdrawal did not differ between groups, being 8.0 +/- 1.2 fL in the Relapse group vs. 8.0 +/- 1.0 fL in the Remission group (p=0.81). However, we found that the relapse MPV was higher than the withdrawal MPV in the Relapse group (9.2 +/- 1.3 fL) than it was in the Remission group (8.0 +/- 1.2 fL, p=0.00). Conclusions: Higher relapse MPV in Relapse group but similar MPV levels in both groups at ATD withdrawal may be attributed to hypermetabolism or hyperthyroidism rather than autoimmunity of GD.Item Value of shear wave elastography by virtual touch tissue imaging quantification in patients with diffuse thyroid gland pathology(2018) Haberal, Kemal Murat; Kural Rahatli, Feride; Turnaoglu, Hale; Kirnap, Nazli Gulsoy; Turhan İyidir, Ozlem; Soudmand, Aresh; Uslu, Nihal; 0000-0002-8211-4065; 30384566; R-9398-2019Background/aim: This study was performed to assess the diagnostic accuracy of shear wave elastography by virtual touch tissue imaging quantification in patients with diffuse thyroid gland pathology and to differentiate Graves' disease from Hashimoto's thyroiditis. Materials and methods: Thirty patients with Hashimoto's thyroiditis and 22 patients with Graves' disease were evaluated with conventional ultrasonography and shear wave elastography by virtual touch tissue imaging quantification. Thirty healthy participants formed the control group. Ten elastographic measurements of each thyroid lobe were performed in all three study groups. The mean shear wave velocity was calculated and compared between the patients and controls. Results: The mean shear wave velocity of the controls (1.92 +/- 0.14 m/s) was significantly lower than that of the patients with Graves' disease (2.71 +/- 0.22 m/s) and Hashimoto's thyroiditis (2.50 +/- 0.20 m/s). Patients with Graves' disease had significantly higher shear wave velocities than those with Hashimoto's thyroiditis (P < 0.001). Conclusion: Shear wave elastography by virtual touch tissue imaging quantification can be used to discriminate a normal thyroid gland from diffuse thyroid gland pathology after conventional sonography and may assist in the diagnosis of Graves' disease and Hashimoto's thyroiditis.
