Backround: A considerable number of COVID-19 vaccines became available following the outbreak. Yet, various inflammatory and autoimmune complications have been reported following vaccination. We aimed to report the case of a type 1 diabetic patient converting from Hashimoto’s thyroiditis to Graves’ disease after the fourth dose of COVID-19 vaccine, thought to trigger an autoimmune/inflammatory syndrome induced by adjuvants (ASIA syndrome). Case Presentation: A thirty-one-year-old female patient with type 1 diabetes and Hashimoto’s thyroiditis applied to our clinic with complaints of palpitations, anxiety, and weight loss one month after the fourth dose of COVID-19 vaccine (2 doses of CoronaVac + 2 doses of Pfizer/BioNTech). She was receiving levothyroxine 50 mcg/day. When her thyroid function tests showed thyrotoxicosis, we initially considered thyroxine-related exogenous thyrotoxicosis. However, we considered Graves’ disease upon persisting thyrotoxicosis despite thyroxine withdrawal, positive serum TSH receptor antibody titers, and other imaging findings. Therefore, various autoimmune and inflammatory events have been reported after the COVID-19 vaccination. Adjuvants in vaccines can trigger autoimmune events, which lead to ASIA syndrome. COVID-19 vaccines may cause increased TSH receptor antibody levels or change the balance in the activity of blocking and stimulating antibodies, which may cause a conversion from Hashimoto’s to Graves’ disease. Conclusion: This was the first case report where the patient experienced a conversion from Hashimoto’s to Graves’ disease after COVID-19 vaccination, which may ultimately be related to ASIA syndrome. Yet, more data is needed to elucidate such a relationship, and patients should closely be checked regularly after four doses of vaccination.

Background: The response against adjuvants in vaccines is presented as autoimmune/inflammatory syndrome (ASIA). In this case report, we presented both SAT and Graves’ disease in a patient as ASIA following the BNT162b2 mRNA COVID-19 vaccination. Case Presentation: A 31-year-old woman was admitted to the endocrinology outpatient clinic with the complaint of neck pain following the second dose of the BNT162B2 SARS-CoV-2 (Pfizer/BioNTech) vaccine. On physical examination, her thyroid gland was tender on palpation. Her thyroid function tests were compatible with hyperthyroidism, and inflammatory markers were high. In the thyroid ultrasonography (US) examination, we observed bilateral diffuse hypoechoic areas in the thyroid gland and increased vascularity in some parts of the thyroid. Anti-thyroid stimulating hormone receptor antibodies (TRAB) were positive. Overall, we considered concurrent subacute thyroiditis (SAT) and Graves’ disease. Conclusion: The present study may be the first report to evaluate SAT and Graves’ disease as ASIA following mRNA COVID-19 vaccination. Clinicians should be aware of possible vaccine-related complications.

Context The aims of the study are to compare characteristics of subacute thyroiditis (SAT) related to different etiologies, and to identify predictors of recurrence of SAT and incident hypothyroidism. Methods This nationwide, multicenter, retrospective cohort study included 53 endocrinology centers in Turkey. The study participants were divided into either COVID-19–related SAT (Cov-SAT), SARS-CoV-2 vaccine–related SAT (Vac-SAT), or control SAT (Cont-SAT) groups. Results Of the 811 patients, 258 (31.8%) were included in the Vac-SAT group, 98 (12.1%) in the Cov-SAT group, and 455 (56.1%) in the Cont-SAT group. No difference was found between the groups with regard to laboratory and imaging findings. SAT etiology was not an independent predictor of recurrence or hypothyroidism. In the entire cohort, steroid therapy requirement and younger age were statistically significant predictors for SAT recurrence. C-reactive protein measured during SAT onset, female sex, absence of antithyroid peroxidase (TPO) positivity, and absence of steroid therapy were statistically significant predictors of incident (early) hypothyroidism, irrespective of SAT etiology. On the other hand, probable predictors of established hypothyroidism differed from that of incident hypothyroidism. Conclusion Since there is no difference in terms of follow-up parameters and outcomes, COVID-19– and SARS-CoV-2 vaccine–related SAT can be treated and followed up like classic SATs. Recurrence was determined by younger age and steroid therapy requirement. Steroid therapy independently predicts incident hypothyroidism that may sometimes be transient in overall SAT and is also associated with a lower risk of established hypothyroidism.

Aim: A co-formulation containing insulin degludec and insulin aspart (IDegAsp) is available for the treatment of diabetes in Turkey. We aimed to evaluate the clinical results of switching to IDegAsp treatment for Type 2 diabetes. Method: A total of 217 patients with type 2 diabetes treated with IDegAsp and having follow-up data were included. The patients were divided into 3 groups. Group 1 switched from basal insulin to IDegAsp, group 2 switched from twice-daily premixed insulin regimen to IdegAsp, and group 3 switched from intensive and thrice-daily premixed insulin regimen to IDegAsp. Groups were evaluated in terms of changes in insulin dose, the number of injections, and changes in HbA1c. Results: The mean follow-up period was 7.5 ± 4.4 months. The mean age was 62.8 ± 12.9 years. The mean duration of diabetes was 15.3 ± 8 years. There was a significant decrease in HbA1c and glucose (p < 0.0001 and p < 0.0001, respectively). HbA1c was significantly reduced in group 1 (p < 0.0001) while insulin dose and the number of injections increased (p < 0.0001 and p < 0.0001, respectively). HbA1c, insulin dose, and the number of injections in group 2 and group 3 (p = 0.001, p = 0.002, p < 0.0001, respectively, and p < 0.0001, p = 0.043, p < 0.0001, respectively) were significantly reduced. Conclusion: This study includes real-life experiences involving a remarkable number of patients in the literature. IDegAsp treatment provided effective blood glucose regulation and caused a significant decrease in the insulin dose and the number of injections, resulting in increased quality of life among those who had to receive twice or more insulin injections.

Introduction Targeting better glycated hemoglobin (HbA1c) and blood pressure (BP) goals may endanger older adults with type 2 diabetes mellitus (T2DM). Overtreatment of T2DM and hypertension is a trending issue, although undertreatment is still common. We investigated the rates and predictors of overtreatment and undertreatment of glycemia and BP in older adults with T2DM and physicians' attitudes to deintensify or intensify treatment. Methods Data from older adults (>= 65 years) enrolled in a large nationwide T2DM survey in 2017 across Turkey were analyzed. Overtreatment of glycemia was defined as HbA1c < 6.5% plus the use of >= 2 oral antihyperglycemics or insulin, and BP overtreatment was defined as systolic BP (SBP) < 120 mmHg or diastolic BP (DBP) < 65 mmHg plus the use of >= 2 drugs. Undertreatment of glycemia was defined as HbA1c > 9%, and BP undertreatment was defined as SBP > 150 mmHg or DBP > 90 mmHg. Deintensification or intensification rates were calculated according to treatment modification initiated by the treating physician(s). Results the rate of overtreatment in the glycemia group (n = 1264) was 9.8% (n = 124) and that in the BP group (n = 1052) was 7.3% (n = 77), whereas the rate of undertreatment was 14.2% (n = 180) and 15.2% (n = 160), respectively. in the adjusted model, use of oral secretagogues (sulfonylureas or glinides) (odds ratio [OR] 1.94, 95% confidence interval [CI] 1.2-3.1) and follow-up at a private clinic (OR 1.81, 95% CI 1.0-3.3) were predictors of glycemia overtreatment. BP overtreatment was independently associated with the use insulin-based diabetes therapies (OR 1.86, 95% CI 1.14-3.04). There was no independent association of BP undertreatment to the study confounders. the deintensification and intensification rates were 25 and 75.6%, respectively, for glycemia and 10.9 and 9.2%, respectively, for BP. Conclusions the results show that one in ten older adults with T2DM are overtreated while one in four require modification of their current antihyperglycemic and antihypertensive treatments. Physicians are eager to intensify medications while they largely ignore deintensification in diabetes management. These results warrant enforced measures to improve the care of older adults with T2DM.

Objectives:Diabetes mellitus is a risk factor for atrial fibrillation and thromboembolism. CHA2DS2VASC score is a scoring system indicating risk of thromboembolism in atrial fibrillation. As it also includes risk factors for atrial fibrillation, it may also indicate a heightened atrial fibrillation risk. Herein, we investigated the role of CHA2DS2VASC score and diabetes-related factors for determining paroxysmal atrial fibrilallation incidence in 24-hour rhythm monitorization among type 2 diabetic patients.Materials and Methods:We retrospectively analyzed type 2 diabetic patients older than 18 years of age who underwent 24-hour rhythm monitoring at Başkent University, Faculty of Medicine, Department of Cardiology between January 2012 and January 2017. The patients’ CHA2DS2VASC scores, clinical and demographic parameters, and transthoracic echocardiography findings were recorded. The correlations between paroxysmal atrial fibrillation and study parameters was analyzed. Multivariate analysis was used to determine significant independent predictors of atrial fibrillation. ROC analysis were done to determine the best cut-off points for significant predictors of atrial fibrillation.Results:A total of 65 (17.2%) of 378 patients had atrial fibrillation in 24-hour rhythm monitoring. The patients with atrial fibrillation had a significantly greater CHA2DS2VASC score. The patients with atrial fibrillation were significantly older, had a longer diabetes duration, and a larger left atrium. Age, diabetes duration, CHA2DS2VASC score, and left atrial diameter were significantly correlated with atrial fibrillation while CHA2DS2VASC score was a significant independent predictor of paroxysmal atrial fibrillation in 24-hour rhythm monitoring. The patients with a CHA2DS2VASC score of equal to or greater than 3 had a significantly greater incidence of paroxysmal atrial fibrillation.Conclusion:Among type 2 diabetics, CHA2DS2VASC score is a significant predictor of atrial fibrillation in 24-hour rhythm monitoring. Atrial fibrillation should be suspected in type 2 diabetics with a high CHA2DS2VASC score. Randomized controlled studies are needed in this field.

Introduction The aim of our study was to investigate the effect of thyroid dysfunction on tendons and the contribution of Acoustic Radiation Force Impulse (ARFI) elastography to the diagnosis of tendinopathy. Methods Eighty Achilles tendons of 40 patients under levothyroxine treatment, who had previously known hypothyroidism but high serum thyroid stimulating hormone levels, and 80 Achilles tendons of 40 healthy individuals were evaluated with ARFI (Virtual Touch Quantification®). 19 of 40 of the patients with hypotiroidism’ Achilles tendons were re-evaluated after thyroid stimulating hormone levels reached to normal limits following the adjustments in thyroid hormone replacement therapy. The middle portion of the each Achilles tendon was chosen for the examination. Every examination consisted of three to five independent measurements (shear wave velocity- meters per second). The mean shear wave velocity value was calculated for each tendon, and used for statistical analysis. Results The stiffness values of both left and right Achilles tendons, represented as shear wave velocity, were similar in patients with hypothyroidism and control group. There was no significant difference between the Achilles tendon shear wave velocity measurements of 19 of 40 hypothyroidism patients who were re-evaluated after the adjustments in thyroid hormone replacement therapy. Conclusions The lack of significant difference in Achilles tendon stiffness between non-naive hypothyroid patients and the control group may be explained as a positive clinical effect of thyroid hormone replacement therapy.

The present survey aimed to find out the demographical and clinical characteristics of patients with hypertension in a population with type 2 diabetes mellitus (T2DM) in Turkey.Patients with T2DM who were followed-up in tertiary endocrine units for at least last one year were recruited. Demographic, clinical and biochemical data of the patients were collected. Hypertension was defined as taking anti-hypertensive medications or having office arterial blood pressure (ABP) ≥140/90 mmHg or home ABP ≥ 130/80 mmHg.A total of 4756 (58.9% women) diabetic patients were evaluated. The percentage of patients with hypertension was 67.5% (n = 3212). Although 87.4% (n = 2808) of hypertensive patients were under treatment, blood pressure was on target in 52.7% (n = 1479) of patients. Hypertension proportions were higher in woman (p = 0.001), older, more obese, and those who had longer diabetes duration, lower education levels, higher frequency of hypoglycemic events (all p0.001) and higher triglyceride levels (p = 0.003). LDL cholesterol level and the percentage of smokers were lower in hypertensive group than in non-hypertensive group (both p0.001). The percentage of macro and microvascular complications was higher in the hypertensive group than in the normotensive one (both p0.001). In multivariate logistic regression analysis, being a woman (OR: 1.26, 95% CI: 1.04-1.51, p = 0.016), smoking (OR: 1.38, 95% CI: 1.05-1.80, p = 0.020), regular physical activity (OR: 1.24, 95% CI: 1.01-1.53, p = 0.039) and the presence of macrovascular complications (OR: 1.38 95% CI: 1.15-1.65, p = 0.001) were the significant predictors of good ABP regulation. The ratios of masked and white coat hypertension were 41.2% and 5.7%, respectively.Our findings indicate that two-thirds (67.5%) of adult patients with T2DM have hypertension. Co-existence of hypertension increases the frequency of macro and microvascular diabetic complications in these patients. Despite the critical role of hypertension in morbidity and mortality, only half of the patients have favorable ABP levels. Masked hypertension seems to be another important issue in this population.

BACKGROUND: Cardiovascular morbidity and mortality are higher among patients with type 2 diabetes, particularly those with concomitant cardiovascular diseases, than in most other populations. We assessed the effects of lixisenatide, a glucagon-like peptide 1-receptor agonist, on cardiovascular outcomes in patients with type 2 diabetes who had had a recent acute coronary event.METHODS: We randomly assigned patients with type 2 diabetes who had had a myocardial infarction or who had been hospitalized for unstable angina within the previous 180 days to receive lixisenatide or placebo in addition to locally determined standards of care. The trial was designed with adequate statistical power to assess whether lixisenatide was noninferior as well as superior to placebo, as defined by an upper boundary of the 95% confidence interval for the hazard ratio of less than 1.3 and 1.0, respectively, for the primary composite end point of cardiovascular death, myocardial infarction, stroke, or hospitalization for unstable angina.RESULTS: The 6068 patients who underwent randomization were followed for a median of 25 months. A primary end-point event occurred in 406 patients (13.4%) in the lixisenatide group and in 399 (13.2%) in the placebo group (hazard ratio, 1.02; 95% confidence interval [CI], 0.89 to 1.17), which showed the noninferiority of lixisenatide to placebo (PCONCLUSIONS: In patients with type 2 diabetes and a recent acute coronary syndrome, the addition of lixisenatide to usual care did not significantly alter the rate of major cardiovascular events or other serious adverse events.
