Öğe Adherence to insulin treatment in insulin naive type 2 diabetic patients: results of telephonic intervention(Springer, 2014) Göğaş Yavuz, Dilek; Bilen, Habip; Sancak, Seda; Galip, Tayfun; Hekimsoy, Zeliha; Şahin, İbrahim; Güvener, Nilgün; Yılmaz, Murat[No Abstract Available]Öğe Effects of Treatment Adherence on Quality of Life in Hypoparathyroid Patients(Georg Thieme Verlag Kg, 2021) Anaforoglu, İnan; Sancak, Seda; Akbaş, Emin Murat; Oruk, Guzide Gonca; Canat, Masum; Tezcan, Kadriye Aydin; Topbas, Murat; Bilir, Betül EkizObjectives This study aimed to evaluate the current situation of hypoparathyroid patients and to investigate the relationship between treatment adherence and quality of life. Study design Prospective, multicentre study. Methods Adult patients presenting with the diagnosis of hypoparathyroidism to 20 different endocrinology clinics were included. They were receiving conventional therapies for hypoparathyroidism, using calcium, active vitamin D, and magnesium. We collected data on demographic features, disease- and treatment-related information, and results of routine laboratory tests, treatment adherence, and presence of complications. Beck Depression Inventory, Beck Anxiety Inventory, and Short Form-36 quality of life assessments were administered. Results Among the 300 patients studied, 60.7 % were adherent to their treatment, and 34.1 % had complications. Anxiety and depression scores were significantly higher in non- adherent versus treatment-adherent patients (p < 0.001 and p = 0.001, respectively). Most of the domains of quality-of-life scores were also significantly lower in non-adherent patients. Both anxiety and depression scores showed significant, negative correlations with serum calcium and magnesium concentrations ( r = -0.336, p < 0.001 and r = -0.258, p < 0.001, respectively). Conclusions Nearly 40 % of the patients were non-adherent to conventional treatment for hypoparathyroidism, and such patients had higher anxiety and depression scores and poorer quality of life scores. Conventional treatment might not be sufficient to meet the needs of patients with hypoparathyroidism. In addition to seeking new therapeutic options, factors influencing quality of life should also be investigated and strategies to improve treatment adherence should be developed.Öğe High Prevalence of TSHR/Gs alpha Mutation-negative Clonal Hot Thyroid Nodules (HNs) in a Turkish Cohort(Georg Thieme Verlag Kg, 2011) Sancak, Seda; Jaeschke, Holger; Eren, Funda; Özlem, T.; Güllüoğlu, Bahadır; Şen, L. S.; Eszlinger, Markus; Bircan, R.Whereas the majority of hot thyroid nodules are caused by somatic TSH-receptor mutations, the percentage of TSH-receptor mutation negative clonal hot nodules (HN) and thus the percentage of hot nodules likely caused by other somatic mutations are still debated. This is especially the case for toxic multinodular goiter (TMNG). 35 HNs [12 solitary hot nodules (SHN), 23 TMNG] were screened for somatic TSHR mutations in the exons 9 and 10 and for Gs alpha mutations in the exons 7 and 8 using DGGE. Determination of X-chromosome inactivation was used for clonality analysis. Overall TSHR mutations were detected in 14 out of 35 (40%) HNs. A nonrandom X-chromosome inactivation pattern was detected in 18 out of 25 (72%) HNs suggesting a clonal origin. Of 15 TSHR or Gs alpha mutation negative cases 13 (86.6%) showed nonrandom X-chromosome inactivation, indicating clonal origin. The frequency of activating TSHR and/or Gs alpha mutations was higher in SHNs (9 of 12) than in TMNGs (6 of 23). There was no significant difference for the incidence of clonality for HNs between TMNGs or SHNs (p: 0.6396). Activating TSHR and/or Gs alpha mutations were more frequent in SHNs than in TMNG. However, the frequency of clonality is similar for SHN and TMNG and there is no significant difference for the presence or absence of TSHR and/or Gs alpha mutations of clonal or polyclonal HNs. The high percentage of clonal mutation-negative HNs in SHN and TMNG suggests alternative molecular aberrations leading to the development of TSHR mutation negative nodules.Öğe Impact of telephonic interviews on persistence and daily adherence to insulin treatment in insulin-naive type 2 diabetes patients: dropout study(Dove Medical Press Ltd, 2016) Göğaş Yavuz, Dilek; Bilen, Habip; Sancak, Seda; Garip, Tayfun; Hekimsoy, Zeliha; Şahin, İbrahim; Güvener, Nilgün; Yılmaz, MuratObjective: The objective of this study is to evaluate the impact of sequential telephonic interviews on treatment persistence and daily adherence to insulin injections among insulin-naive type 2 diabetes patients initiated on different insulin regimens in a 3-month period. Methods: A total of 1,456 insulin-naive patients with type 2 diabetes (mean [standard deviation, SD] age: 56.0 [12.0] years, 49.1% were females) initiated on insulin therapy and consecutively randomized to sequential (n=733) and single (n=723) telephonic interview groups were included. Data on insulin treatment and self-reported blood glucose values were obtained via telephone interview. Logistic regression analysis was performed for factors predicting increased likelihood of persistence and skipping an injection. Results: Overall, 76.8% patients (83.2% in sequential vs 70.3% in single interview group, (P<0.001) remained on insulin treatment at the third month. Significantly higher rate for skipping doses was noted in basal bolus than in other regimens (27.0% vs 15.0% for premixed and 15.8% basal insulin, respectively, P<0.0001). Logistic regression analysis revealed sequential telephonic interview (odds ratio [OR], 1.531; 95% confidence interval [CI], 1.093-2.143; P=0.013), higher hemoglobin A1c levels (OR, 1.090; 95% CI, 0.999-1.189; P=0.049), and less negative appraisal of insulin therapy as significant predictors of higher persistence. Basal bolus regimen (OR, 1.583; 95% CI, 1.011-2.479; P=0.045) and higher hemoglobin A1c levels (OR, 1.114; 95% CI, 1.028-1.207; P=0.008) were the significant predictors of increased likelihood of skipping an injection. Conclusion: Our findings revealed positive influence of sequential telephonic interview, although including no intervention in treatment, on achieving better treatment persistence in type 2 diabetes patients initiating insulin.Öğe Out-of-Reference Range Thyroid-Stimulating Hormone Levels in Levothyroxine-Treated Primary Hypothyroid Patients: A Multicenter Observational Study(Frontiers Media Sa, 2017) Göğaş Yavuz, Dilek; Yazıcı, Dilek; Keskin, Lezzan; Atmaca, Ayşegül; Sancak, Seda; Saraç, Fulden; Asmaz, Özlem; Yılmaz, MuratObjective: Although levothyroxine (LT4) replacement therapy for hypothyroidism has been established as safe, inexpensive and effective, many studies from different countries reported out-of-reference range thyroid-stimulating hormone (TSH) values for the hypothyroid patients under LT4 treatment. The aim of this study was to determine TSH levels of primary hypothyroid patients under LT4 treatment and to assess self-reported compliance with daily LT4 intake in tertiary care centers in Turkey. Design: In this cross-sectional, observational study, adult patients with primary hypothyroidism, receiving LT4 treatment for at least 6 months, were included. The patients were from 12 tertiary care centers in 9 cities of Turkey. TSH and free T4 levels were recorded from patient files and self-reported compliance with daily LT4 intake was assessed by interviewing the subjects at the last visit. Results: A total of 1,755 subjects (46 +/- 13 years; F/M: 89.9/10.1%) with primary hypothyroidism were enrolled. Of the hypothyroid subjects, 44.8% had out-of-reference range serum TSH levels. TSH values were over the reference range (TSH > 4 mIU/L) in 26.2% and were under the reference range (TSH < 0.5 mIU/L) in 18.6% of the patients. Total duration of LT4 treatment was 5.9 +/- 4.7 years and mean dose was 1.2 +/- 0.6 mu g/kg/day. Non-compliant patients (31.1%) had higher TSH levels (6.9 +/- 16 vs 3.8 +/- 0.9 mIU/L, P = 0.01) compared to compliant patients. Conclusion: The results of this study revealed that nearly half of the hypothyroid patients had out-of-reference range serum TSH values, despite under LT4 treatment. Compliance with LT4 treatment seems to be one of the major determinants to reach the target TSH levels in hypothyroid patients.
