ABSTRACT

OBJECTIVE: Proton pump inhibitor (PPI) drugs reduce gastric acid secretion and lead to an increase in serum gastrin levels. Many preclinical and some clinical researches have established some positive effects of gastrin or PPI therapy on glucose regulation. The aim of this study was to prospectively investigate the short term effects of esomeprazole on glycaemic control in patients with type 2 diabetes mellitus. In addition, the presence of an association between this effect and gastrin levels was evaluated. METHODS: Thirty-two subjects with type 2 diabetes mellitus were enrolled and grouped as intervention (n=16) and control (n=16). The participants in the intervention group were prescribed 40 mg of esomeprazole treatment for three months. At the beginning of the study and at the 3rd month, HbA1c level (%) and gastrin levels (pmol/L) of participants were assessed. Then, the groups were compared in terms of their baseline and 3rd month values. RESULTS: In the intervention group, the mean gastrin level increased significantly from 34.3±14.4 pmol/L to 87.4±43.6 pmol/L (p<0.001). The mean HbA1c level was similar to the pre-treatment level (6.3±0.7% vs. 6.4±0.9%, p=0.441). There were no statistically significant differences in all parameters of the control group. The majority of individuals were on metformin monotherapy (65.6 %). The subgroup analysis of metformin monotherapy revealed that, in intervention group, there was a significant increase in gastrin levels (39.9±12.6 vs. 95.5±52.5, p=0.026), but the HbA1c levels did not change (6.0±0.4 % vs. 5.9±0.6 %, p=0.288); and in control group, gastrin levels did not change (37.5 ± 26.7 vs. 36.1 ±23.3, p=0.367), but there was an increase in HbA1c levels (6.1 ± 0.50 vs. 6.4 ± 0.60, p=0.01). CONCLUSION: Our study demonstrates that esomeprazole has no extra benefit for the controlled diabetic patient in three months. However, in only the metformin-treated subgroup, esomeprazole may prevent the rise in HbA1c level.

ABSTRACT

Objective: Type 1 diabetes (T1D) is a disease characterized by severe insulin deficiency. In 2008 our group studied the prevalence of diabetes in adults between 20-80 years of age in Cyprus but data regarding this incidence in the pediatric population is lacking. The objective of this study was to report the incidence of T1D among permanent inhabitants aged 16 years or younger between 2001-2016 in Cyprus. Methods: This study was a retrospective analysis. The patients were mainly evaluated and recorded at Dr. Burhan Nalbantoglu Hospital, Nicosia. Data was also reviewed from Famagusta Government Hospital, Kyrenia Government Hospital, Near East University Hospital and the Cyprus Turkish Diabetes Association. Results: A total of 107 subjects were diagnosed as T1D between 2001 and 2016 in the pediatric age group. Forty-nine (45.7%) were girls and 58 (54.3%) were boys. Of these 38.7% were resident in Nicosia, 30.2% Famagusta, 12.3% Kyrenia, 9.4% Guzelyurt and 7.5% Iskele. The proportion of newly diagnosed T1D was highest among children aged 9-12 years (35.5%) followed by children aged 5-8 years (32.7%). Newly diagnosed T1D most frequently presented in March and April. The overall mean incidence rate was 11.1/100,000 between 2001 and 2016. The incidence rates were similar and comparable among the years. Conclusion: This study is the first to analyze the incidence of T1D in Cyprus. Compared to other countries the incidence rate is intermediate. Our findings are similar to the incidence rates of T1D in South Cyprus and Turkey.

ABSTRACT

OBJECTIVE: Colorectal polyps and thyroid nodules are common disorders linked to hyperinsulinemia and metabolic syndrome (Mets). The direct association between these two diseases is not clear. We aimed to analyze the prevalence of thyroid nodules in subjects with and without colorectal polyps. The secondary aim was to establish the prevalence of Mets and its parameters in both disorders and to determine if insulin resistance and hyperinsulinemia are common underlying pathophysiological mechanisms. SUBJECTS AND METHODS: One hundred and five subjects with colorectal polyps (71 males, 34 females) and 68 controls (28 males, 40 females) were enrolled. The parameters of Mets together with TSH, insulin, low-density lipoprotein cholesterol, and homeostasis model for assessment of insulin resistance levels were calculated. We performed thyroid ultrasonography in all participants. RESULTS: The prevalence of Mets was similar in the colorectal polyp and control groups (37.1 vs. 37.3%, p = 0.982). The prevalence of Mets was nonsignificantly higher in subjects with a documented thyroid nodule compared to subjects without a thyroid nodule (43.0 vs. 32.6%, p = 0.205). The prevalence of thyroid nodules in subjects with colorectal polyps was significantly higher than in subjects without polyps (52.9 vs. 35.3%, p = 0.017). Compared to subjects with no colorectal polyps, we established a significant increase in the odds of having thyroid nodules (OR 2.05; 95% CI: 1.097-3.860, p = 0.017). The presence of colorectal polyps and age in the adjusted model were established to be independent risk factors for having thyroid nodules (p = 0.025 and p = 0.007, respectively). CONCLUSION: These results may support the presence of other common mechanisms in the development of these two pathologies other than insulin resistance and hyperinsulinemia.

ABSTRACT

OBJECTIVE: The objective of this study was to assess the antiproliferative pleiotropic effects of statins on thyroid function, volume, and nodularity. SUBJECTS AND METHODS: One hundred and six hyperlipidemic patients were included in this prospective study. The 69 patients in the statin groups received atorvastatin (16 received 10 mg and 18 received 20 mg) or rosuvastatin (20 received 10 mg and 15 received 20 mg). The 37 patients in the control group, assessed as not requiring drugs, made only lifestyle changes. Upon admission and after 6 months, all patients were evaluated by ultrasonography as well as for lipid variables (total cholesterol, high- and low-density lipoprotein cholesterol, and triglycerides) and thyroid function and structure. RESULTS: After 6 months, no differences in thyroid function, thyroid volume, the number of thyroid nodules, or nodule size were observed in the statin and control groups. In a subgroup analysis, total thyroid volume had decreased more in patients receiving 20 mg of rosuvastatin than that in the control group (p < 0.05). Maximum nodule size had decreased more in those receiving 10 mg of rosuvastatin (p < 0.05). CONCLUSIONS: Our results suggest an association between rosuvastatin treatment and smaller thyroid volume and maximum nodule diameter; this could be attributable to the antiproliferative effects of statin therapy on the thyroid.

ABSTRACT

Serum calcitonin is a tumor marker used in the diagnosis and follow-up of medullary thyroid carcinoma. Calcitonin washout evaluation is a new method used for suspicious thyroid nodules and lymph nodes. Limited clinical data are present about the efficacy of this method. A 61-year-old female patient with known Hashimoto's thyroditis and an 8-mm hypoechoic nodule was presented with one previously benign fine-needle aspiration cytology (FNAC). On referral to our department, she had a moderately high-serum calcitonin level, and we repeated the FNAC that was reported as nondiagnostic. We performed FNAC for the third time together with calcitonin washout evaluation from the thyroid nodule. The FNAC was again nondiagnostic, but the calcitonin washout level from the thyroid nodule was 152.569 pg/mL. Total thyroidectomy was performed, and the diagnosis was confirmed as medullary thyroid carcinoma. Calcitonin washout evaluation may be a useful method in the differential diagnosis of patients with thyroid nodules having moderately high-serum calcitonin levels.

ABSTRACT

Amyloidosis is characterized by accumulation of amorphous, proteinaceous material in various organs and tissues of the body. Amyloid may accumulate in the thyroid gland in cases of medullary thyroid carcinoma and systemic amyloidosis. Amyloid accumulates extracellularly in the thyroid parenchyma and disrupts the normal follicular patterns. Most of the cases reported up to now were clinically euthyroid, but many presentation forms and overlaps have been reported. Herein we present a patient with toxic nodular goiter with amyloid deposition in the toxic nodule as well as the remaining thyroid tissue.

ABSTRACT

OBJECTIVES: The purpose of this study was to evaluate the relationship between body mass index and lipid profiles with breast cancer prognosis together with the relationship of these parametres with known breast cancer prognostic indices including c-erbB2 expression. PATIENTS AND METHODS: Four hundred and thirty-three patients diagnosed with breast cancer at Ankara University, Faculty of Medicine, Department of Medical Oncology made up the study population. The primary endpoints were relapse and death. Body mass index at the time of diagnosis, lipid levels at the time of diagnosis, estrogen receptor status, progesterone receptor status, c-erbB2 expression, tumor grade, patient age, axillary lymph node involvement level, tumor stage, menopausal status and surgery details were taken into account. RESULTS: The mean body mass indices were similar in the remission, relapse and mortality groups. Patients with body mass indices higher than 30 kg/m² had a lower incidence of c-erbB2 expression when compared to patients with body mass indices < 18.5 kg/m(2) (19 vs. 50 %, p = 0.009). Survival analysis revealed that patients with body mass indices < 18.5 kg/m(2) had significantly shorter disease free survivals when compared to patients with body mass indices between 25 and 29.9 kg/m(2). Mean serum lipid levels were similar in the remission, relapse and mortality groups. A trend toward relapse was shown in patients with total cholesterol > 240 mg/dl, but this was statistically insignificant. Survival analysis revealed that patients with triglyceride levels lower than 150 mg/dl had a statistically significant longer disease-free survival when compared to the other groups. Again a trend towards shorter overall survival was seen in patients with total cholesterol > 240 mg/dl, but this relationship was also statistically insignificant. CONCLUSION: Most large previous studies reported adverse breast cancer outcome with obesity. However in our study, patients with lower body weight had a shorter disease-free survival. This could be explained by the low number of patients in this study, genetic profile of the patient population, possible weight changes after treatment and the inverse relationship between body mass index and c-erbB2 expression.

ABSTRACT

Hashimoto's Thyroiditis (HT) is an autoimmune disease and the most frequent cause of hypothyroidism. Subacute thyroiditis (SAT) overlapping HT is a rare entity. A 69-year-old female patient with HT and multinodular goiter has been followed on levothyroxine replacement therapy for 7 years. She presented with neck pain radiating to the right ear persisting for 2 months. She was prescribed analgesics and antibiotics by other physicians during that period, which did not work. Her vital signs were stable with no tachycardia or fever. The right lobe of the thyroid gland was tender on palpation. Her TSH level was 3.94 mIU/ml, ESR 23 mm/h, CRP 3.2 mg/l, WBC 4900/µl at presentation. Thyroid ultrasonography revealed a hypoechoic area over the tender lobe. Power Doppler imaging revealed almost no blood flow in that area. She was started on methylprednisolone 32 mg/day. At day 10 of therapy, her symptoms had completely resolved. Ultrasonography repeated showed that the hypoechoic area had disappeared. Glucocorticoid dosage was tapered and stopped. Emergence of subacute thyroiditis in a case with preexisting Hashimoto's thyroiditis is a quite rare condition, but should be kept in mind along with a painful attack of HT in the differential diagnosis.

ABSTRACT

Malignant mesothelioma is a rare but notoriously chemoresistant tumor. An impressive activity of gemcitabine and cisplatin combination in malignant mesothelioma has been shown. However, the hematological toxicity and nephrotoxicity related to this regimen affect the patient's life negatively. The aim of this study is to investigate the efficacy and toxicity of divided dose of cisplatin combined with gemcitabine in chemo-naïve patients with malignant mesothelioma. Twenty-six eligible patients with malignant mesothelioma were enrolled onto the study. Cisplatin 35 mg/m(2) and gemcitabine 800 mg/m(2) were administered on days 1 and 8 as intravenous infusion in a 3-week cycle, up to maximum 6 cycles. Response and toxicity evaluations were performed in 26 patients. Male-female ratio was 11/15 with a mean age of 50.5 years (37-70). Locations of tumor were pleura in 16 patients, and peritoneum in 10 patients. All patients had epitheloid subtype of malignant mesothelioma. The partial response and stable disease were observed in 6 patients (23.1%) and in 13 patients (50%), respectively, with an overall tumor control rate of 73.1%. Seven patients (26.9%) had progressive disease. Median time to disease progression and survival were 4 and 19.5 months, respectively. Grade 3 nausea and vomiting were observed in one patient (3.8%), grade 4 neutropenia developed in one patient (3.8%) and grades 3-4 thrombocytopenia and nephrotoxicity did not develop. There was no treatment related death. Divided dose of cisplatin combined with gemcitabine, at the current dosage and schedule, appears to be an active regimen in chemotherapy-naïve patients with malignant mesothelioma, and well-tolerated.
