    HIGH THYROPEROXIDASE ANTIBODY TITERS MAY PREDICT RESPONSE TO ANTITHYROID DRUG TREATMENT IN GRAVES DISEASE: A PRELIMINARY STUDY
    (Editura Acad Romane, 2023) Gokbulut, P.; Koc, G.; Kuskonmaz, S. M.; Onder, C. E.; Omma, T.; Firat, S.; Culha, C.
    Background and aim. Antithyroid drugs are first treatment for Graves hyperthyroidism worldwide. Although remission can be achieved in approximately 40-50% of patients in 12-18 months with antithyroid drugs, this period can be extended up to 24 months. We aimed to evaluate the effect of individual clinical/biochemical variables and GREAT score in predicting response to antithyroid drug in Graves disease.Material and methods. This is a retrospective single-center study including 99 patients with the first episode of Graves disease treated for at least 18 months. The patients were classified into two groups as those who responded to antithyroid medication at 18-24 months (group 1) and those who did not respond at 24 months and continued with low-dose antithyroid medication (group 2).Results. Medical treatment response was obtained in 38 (38.3%) of the patients at 18 months, and in 19 (19.1%) patients at 24 months. Long-term medical treatment (>24 months) was given to the remaining 43 patients due to the lack of response to medical treatment. Thyroid volume and free T4 levels were higher in those followed up with long-term antithyroid drugs, and orbitopathy was more common in this group. Median anti TPO value was significantly higher in group 1 when compared to group 2 (593 U/l and 191.6 U/l respectively). More patients were classified as GREAT class 3 in group 2 when compared to group 1 (46.5% and 12,5% respectively). We analyzed the Thyroperoxidase Antibody(anti TPO) titers, which we divided into three levels, according to groups 1 and 2. Post-hoc Chi-Square analysis revealed that falling into the highest anti TPO category was significantly associated with response to medical therapy in 24 months (p <0.05).Conclusion. According to our study, GREAT score and anti TPO Ab titers at presentation may help predict response to ATD in Graves disease.

    Sonographic evaluation of subclinical entheseal involvement in patients with hypoparathyroidism: a case control study
    (Springer, 2023) Firat, S. N.; Kuskonmaz, S. M.; Onder, C. E.; Omma, T.; Genc, H.; Culha, C.
    Purpose Hypoparathyroidism is a disease characterized by low serum calcium, increased serum phosphorus and low PTH levels. Although patients are treated with active vitamin D and calcium, a proper serum calcium phosphorus balance cannot always be achieved. Ectopic calcifications that develop in organs during treatment are the most common complications. To date, there is not any published study on enthesopathy in patients with hypoparathyroidism. The aim of this study was to evaluate subclinical enthesopathy in patients with hypoparathyroidism with ultrasound and to compare the results with those of the control group. Methods The study included patients aged 18-65 years with postoperative hypoparathyroidism and hypothyroidism (group hypoP + hypoT), patients with postoperative hypothyroidism (group hypoT), and healthy age and sex-matched volunteers (group C). Ultrasonographic findings of enthesopathy in both extremities were documented according to the Glasgow Ultrasound Enthesitis Scoring System (GUESS). Results GUESS scores in group hypoP + hypoT, were significantly higher when compared to the other groups. There was a statistically significant correlation between the total GUESS scores and total enthesophyte scores and the duration of hypoparathyroidism (p < 0.05, r = 0.43) (p < 0.05, r = 0.39) respectively. In the correlation analysis of all groups, a significant negative correlation was found between serum Ca and PTH levels and the total GUESS scores (p < 0.01, r = - 0.37; p < 0.01, r = - 0.54, respectively). Conclusion This study showed that GUESS scores were significantly higher in patients with hypoparathyroidism compared to those with hypothyroidism and control subjects. GUESS scores were positively correlated with disease duration. Patients with hypoparathyroidism need to be evaluated for subclinical enthesopathy during follow-up.
