RESUMO

OBJECTIVE: C-peptide is a reliable marker of beta cell reserve and is associated with diabetic complications. Furthermore, HbA1c level is associated with micro- and macro-vascular complications in diabetic patients. HbA1c measurement of diabetic patients with anemia may be misleading because HbA1c is calculated in percent by taking reference to hemoglobin measurements. We hypothesized that there may be a relationship between C-peptide index (CPI) and proteinuria in anemic patients with type 2 diabetes mellitus (T2DM). Therefore, the aim of the present study was to investigate the association between C-peptide levels and CPI in anemic patients with T2DM and proteinuria. METHODS: The patients over 18 years of age with T2DM whose C-peptide levels were analyzed in Endocrinology and Internal medicine clinics between 2014 and 2018 with normal kidney functions (GFR>60 ml/min) and who do not use any insulin secretagogue oral antidiabetic agent (i.e. sulfonylurea) were enrolled into the study. RESULTS: Hemoglobin levels were present in 342 patients with T2DM. Among these 342 cases, 258 (75.4%) were non-anemic whereas 84 (24.6%) were anemic. The median DM duration of the anemic group was statistically significantly higher in T2DM (p=0.003). There was no statistically significant difference found in proteinuria prevalence between non-anemic and anemic patient groups (p=0.690 and p=0.748, respectively). Anemic T2DM cases were corrected according to the age, gender, and duration of DM. C-peptide and CPI levels were not statistically significant to predict proteinuria (p=0.449 and p=0.465, respectively). CONCLUSION: The present study sheds light to the association between C-peptide, CPI, and anemic diabetic nephropathy in T2DM patients and indicates that further prospective studies are needed to clarify this issue.

RESUMO

BACKGROUND: We aimed to investigate the association between platelet indices [platelet, plateletcrit (PCT), mean platelet volume (MPV) and platelet distribution width (PDW)] and gastrointestinal bleeding (GIB), as well as determine its severity and prognosis. METHOD: 500 patients with GIB who were admitted to hospital between March 2014 and February 2017 and diagnosed with "Gastrointestinal System Bleeding", as well as114 healthy individuals were retrospectively included in the study. Patients' platelet indices were recorded after one week and one month from their files. RESULTS: Platelet, PCT, MPV and PDW levels were determined to be higher in the patients with bleeding, when compared to the control group (p < 0.001). Within the first week, a significant reduction was determined in patients' platelet, PCT, MPV and PDW values compared to the admission values (p < 0.001). In initial-month controls, a significant reduction was determined in the platelet indices compared to the initial-week values (p < 0.001). A significant association between bleeding severity and increased platelet indexes was determined. Increasing age, female gender, the presence of comorbidities, high levels of platelet indexes, low levels of hemoglobin, and albumin values were all found to be associated with a poor prognosis. PCT, MPV, and PDW were determined as being the independent risk factors that predict the odds of GIB, alongside the independent predictors that predict risk of bleeding severity and the prognosis. CONCLUSION: We think that platelet indices may be used in diagnosis of GIB, as well as in predicting bleeding severity and the prognosis.

RESUMO

BACKGROUND: The aim of this study is to investigate the serum levels of procalcitonin and its association with autoantibodies in patients with euthyroid Hashimoto's thyroiditis. METHODS: A total of 80 participants were included in the study; 40 of which were newly diagnosed with Hashimoto's thyroiditis, aged over 18, and 40 of which were healthy volunteers. The serum levels of procalcitonin were measured by enzyme-linked immunosorbent assay kit. Thyroid function tests were analyzed in hormone laboratory with Electro-chemiluminescence immunoassay. RESULTS: Hashimoto's thyroiditis patients had higher median procalcitonin levels than those of the control group (34.3 pg/mL vs 27.8 pg/mL respectively; P=.037). Also, male patients had higher median procalcitonin levels as compared to female patients (37 pg/mL vs 27 pg/mL respectively; P=.013). In the Hashimoto's thyroiditis group, procalcitonin level was positively correlated with anti-thyroglobulin and anti-thyroid peroxidase levels (r=.559, P<.001; r=634, P<.001, respectively). The procalcitonin and anti-thyroid peroxidase levels were identified to be an independent predictor in diagnosis of Hashimoto's thyroiditis. CONCLUSIONS: The fact that procalcitonin was found to be correlated with thyroid autoantibodies and found to be an independent risk factor for Hashimoto's thyroiditis in the regression analysis in the framework of this study urges us to think that procalcitonin may be associated with the autoimmunity.

RESUMO

Thrombosis due to abdominal aortic aneurysm is a rare condition that causes high mortality. Transient ischemic attack of the spinal cord can occur as a result of trash emboli from thrombus in abdominal aortic aneurysm. This condition generally occurs during operation of abdominal aortic aneurysm; very rarely, it can also be seen in laminated abdominal aortic aneurysm. Here, we present a case of a patient presenting with bilateral lower extremity paralysis resulting from transient ischemic attack of the spinal cord due to infrarenal abdominal aortic aneurysm.

RESUMO

OBJECTIVE: The aim of this study was to investigate dynamic thiol/disulfide homeostasis in autoimmune subclinical hypothyroidism. METHODS: Forty-eight patients with a new diagnosis of subclinical hypothyroidism due to Hashimoto thyroiditis who were not yet under medical therapy, and 48 healthy control subjects were enrolled. Thiol/disulfide homeostasis [native thiol-disulfide exchanges] was measured in both groups using the automated method developed by Erel and Neselioglu. An absolute difference of 0.5 between the total thiol and native thiol concentrations revealed the disulfide bond amount. RESULTS: The native thiol level (p = 0.014) and native thiol/total thiol ratio (p = 0.001) were lower in patients with subclinical hypothyroidism than in the control group. Meanwhile, the disulfide level (p = 0.004), disulfide/native thiol ratio (p = 0.001), and disulfide/total thiol (p = 0.001) ratio were higher in patients with subclinical hypothyroidism than in the control group. The antithyroid peroxidase and anti-thyroglobulin levels were positively correlated with the disulfide/native thiol ratio (r = 0.339, p = 0.019; r = 0.243, p = 0.023, respectively) and the disulfide/total thiol ratio (r = 0.133, p = 0.019; r = 0.238, p = 0.026, respectively) and negatively correlated with the native thiol/total thiol ratio (r = -0.292, p = 0.004; r = -0.233, p = 0.022, respectively). CONCLUSION: We found that thiol/disulfide homeostasis shifted to disulfide formation in patients with subclinical hypothyroidism and that thyroid autoantibodies were positively correlated with thiol oxidation. It is not clear whether abnormal thiol/disulfide homeostasis is a cause or a consequence in Hashimoto thyroiditis. Further studies are required.

RESUMO

BACKGROUND: The frequency of thyrotoxicosis may vary between countries and some laboratory test results may be used in etiology research. This study aimed to evaluate the prevalence of thyrotoxicosis diagnoses and laboratory test results. METHODS: 3246 patients with overt thyrotoxicosis were included in this study. Laboratory test results, epicrisis, thyroid ultrasonography, thyroid scintigraphy, and radioactive iodine uptake test reports of the patients were examined in the study. RESULTS: Thyrotoxicosis was found due to levothyroxine overdose in 58.1% of the patients. When this group was excluded, 36.1% of the patients were diagnosed with toxic multinodular goiter most frequently. TRab levels were 8.5 times higher in Graves' disease than in other diagnostic groups. Anti-TPO levels were found to be the highest in the Graves' disease and Hashitoxicosis groups compared to other diagnostic groups (p<0.001). Anti-Tg levels were found to be highest in Graves' disease, Postpartum thyroiditis, and Hashitoxicosis patients (p<0.001). The free triiodothyronine / free thyroxine ratio was significantly higher, a cut-off value of >2.94 provided a sensitivity of 66% and specificity of 64% in diagnosing Graves' disease. CONCLUSION: The causes of thyrotoxicosis show some differences between countries. Patients using levothyroxine should be informed about drug use and dose titration. The free triiodothyronine / free thyroxine ratio can be used in addition to other tests during diagnosis.

RESUMO

In this study, we aim to evaluate the presence of endothelial dysfunction in Gilbert syndrome patients with left ventricular mass index (LVMI) and endocan levels. The study included 60 patients who diagnosed with Gilbert syndrome and 60 healthy controls who did not have any known diseases. Human endocan levels were measured using a sandwich ELISA method. The endocan and LVMI levels were lower in the Gilbert syndrome group than in the healthy controls. In the Gilbert syndrome group, total bilirubin level was negatively correlated with LVMI (r = -0246; P = .007) and endocan levels (r = -.270; P = .046). In the Gilbert syndrome group, increasing age (ß ± SE = 20.78 ± 7.47; P = .006), was a positive independent predictor of LVMI, and increasing high-density lipoprotein cholesterol (HDL-C) (ß ± SE = -.27 ± .09; P = .007), and total bilirubin levels (ß ± SE = -6.09 ± 3.02; P = .046) were found to be a negative independent predictor. These results support that endothelial dysfunction is decreased in Gilbert Syndrome patients with mild hyperbilirubinemia compared with the healthy control group.

RESUMO

AIM: Gastric cancer is one of the most common cancers worldwide. In Turkey, stomach cancer is ranked 5th among men and 8th among women in all cancers and is located in the forefront in cancer-related deaths. Signet ring cell adenocarcinoma, which is the histopathological subtype of gastric cancer, has a poor prognosis. The incidence of signet ring cell adenocarcinoma is rising. In the present study, we aimed to describe the clinicopathologic features of signet ring cell adenocarcinoma. MATERIALS AND METHODS: A total of 79 patients with 30 being female (38%) and 49 male (62%) who were diagnosed with gastric signet ring cell adenocarcinoma in the Medical Oncology Department of Ankara Numune Training and Research Hospital between January 2004 and October 2015 were retrospectively evaluated. RESULTS: The baseline demographic characteristics of the patients, such as tumor localization, tumor stage, preoperative serum tumor markers, and treatment type (surgery and chemotherapy regimen), and the effects of these variables on survival and mortality were evaluated. Total surgery, stage III disease, moderate to poor grade, preoperative serum CA 19-9 and CEA levels were found as independent predictors of progression risk (p < 0.05). Each 1 ng/mL increase in preoperative serum CEA level was found to increase the risk of progression by 1.20 folds. Again, each 1 U/mL in preoperative serum CA 19-9 level was found to increase the risk of progression and mortality by 1.06 folds. CONCLUSION: The clinicopathologic features of signet ring cell stomach cancer were described. Tumor localization and disease, CA 19-9 and CEA levels, and treatment type (surgery and chemotherapy regimen) were effective on survival and mortality. However, further studies with larger patient groups are needed on this issue. HOW TO CITE THIS ARTICLE: Altay SB, Akkurt G, Yilmaz N, et al.

RESUMO

AIM: This study aimed to determine oxidant status and left ventricular mass index (LVMI) and their relationship with mild hyperbilirubinemia in patients with Gilbert syndrome (GS). BACKGROUND: Gilbert syndrome (GS) presents with mild indirect hyperbilirubinemia, normal liver function tests, and normal hepatic histology. METHODS: A total of 84 patients, including 41 (48.8%) patients with GS and 43 (51.2%) patients without GS, were included in the study. Total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI) were examined for oxidant status. RESULTS: TAS was found to be higher in the GS patients compared to the non-GS patients (1.7±0.1 vs. 1.5±0.2; p=0.002); there was no significant difference between the groups in terms of mean TOS and mean OSI (p>0.05). No significant difference was observed either between the GS and non-GS patients in terms of mean left ventricular volume and mean LVMI (p>0.05). However, subgroup analysis based on sex revealed that GS patients had a lower LVMI for both sexes. In GS patients, TAS level had a positive correlation with albumin (r=0.319; p=0.042), triglyceride (r=0.392; p=0.011), total bilirubin (r=0.420; p=0.006), direct bilirubin (r=0.361; p=0.020), and indirect bilirubin (r=0.338; p=0.0311) levels; no correlation was found between TAS level and other laboratory findings (p>0.05). The regression model indicated that risk factors of direct bilirubin (ß±SE=0.13±0.03; p<0.001), uric acid (ß±SE=0.04±0.01; p=0.001), and albumin (ß±SE=0.17±0.04; p<0.001) were independent predictors of TAS level. CONCLUSION: This study revealed a relationship between mild hyperbilirubinemia and antioxidant balance in GS. Although statistical significance was not reached, LVMI was found to be lower in the GS group compared to the non-GS group for both sexes.

RESUMO

A 29-year-old male patient was treated and followed up for a pulmonary embolism. The patient had no relevant medical history, other than the fact that he had smoked bonzai, a synthetic cannabinoid derivative, for 2 years. Hypercoagulability tests were normal. The use of synthetic cannabinoids is increasing in the young population and should be kept in mind among the causes of pulmonary embolism.

RESUMO

Peritoneal tuberculosis is a disease which can mimick malignancy especially in women who present with ascites and elevated CA125 levels. It should always be considered in differential diagnosis, but the diagnosis is rarely easy for clinicians. A young female patient who presented with abdomen tenderness and diagnosed with peritoneal tuberculosis as a result of performed tests is discussed hereby in the case report. We expect that this case report adds to the existing literature on this subject.

RESUMO

OBJECTIVE: We aimed to investigate the effects of oxidative stress in the pathogenesis and progression of Hashimoto's thyroiditis (HT). METHODS: Forty euthyroid and 40 subclinical hypothyroid patients older than 18 years and not yet had received treatment were enrolled in the study. RESULTS: In the 9 months follow-up, 14 of the HT patients developed overt hypothyroidism. The mean total oxidant status (TOS) and oxidative stress index (OSI) were higher in patients who developed overt hypothyroidism than those who did not (p < .001). And no significant difference was found between the two groups in terms of paraoxanase-1 and arylesterase (p > .05). Multivariable Cox regression model showed thyroid stimulating hormone level (HR = 1.348, p < .001), free-thyroxine level (HR = 0.481, p = .017) and OSI ratio (HR = 2.349, p < .001) to be independent predictors of development of overt hypothyroidism. OSI level, being over 2.96 with 92.9% sensitivity and 62.5% specificity, predicts the risk of hypothyroidism. CONCLUSION: Oxidative stress may be an effective risk factor in the development of overt hypothyroidism in HT.

RESUMO

This study aimed to examine the relationship between the ratio of monocyte frequency to high-density lipoprotein (HDL) cholesterol level (the monocyte/HDL ratio (MHR)) and asymptomatic organ damage (AOD) in primary hypertension (PHT). A total of 366 participants were enrolled in the study, including 275 cases currently being followed up after a diagnosis of PHT in our clinic and 91 healthy volunteers. The MHR was higher in patients with PHT than in individuals in the control group. In the PHT group, the MHR was higher in patients with AOD (AOD+) than in patients without AOD (AOD-). In the correlation analyses performed in the PHT group, there were positive correlations between the MHR and the following AOD indicators: carotid intima media thickness, left ventricular mass index, urinary protein levels and urinary albumin levels. In a multivariate linear regression analysis, the MHR was found to be an independent risk factor associated with these indicators of AOD. In conclusion, our study shows that MHR is associated with AOD in patients with PHT.

RESUMO

Hypothyroidism is a wide clinical spectrum disorder and only a few cases in literature show this. Rhabdomyolysis and acute renal impairment can be seen concurrently in a hypothyroid state. We report a case of severe hypothyroidism with poor drug compliance leading to rhabdomyolysis and acute kidney injury. LEARNING POINTS: Hypothyroidism is a rare cause of acute kidney injury.In this case report, we studied a rare occurrence of acute renal impairment due to hypothyroidism with poor drug compliance, which induced rhabdomyolysis.Our report emphasized that thyroid status should be evaluated in patients with unexplained acute renal impairment or presenting with the symptoms of muscle involvement.

RESUMO

Hypernatremia is a common electrolyte disorder associated with prolonged hospitalization and death. Severe hypernatremia is defined as a serum sodium (Na(+)) concentration >160 mmol/L. To the best of our knowledge, there is little information on patients with severe hypernatremia, Na(+) >160 mmol/L. Therefore, in this study, we aimed to determine the frequency, demographic and clinical characteristics, comorbid conditions and treatment strategies in patients presenting to the emergency department with severe hypernatremia, and also to evaluate the effects of these factors on mortality. A retrospective chart review was performed on patients presenting to the emergency department between January 2011 and June 2014. Patients with Na(+) >160 mmol/L were screened retrospectively via the hospital electronic information management system and patient medical record files. During the 3.5 years of screening, 256 patients (0.04 %) with Na(+) >160 mmol/L presented to the emergency department. The mean age of the patients included in the study was 74.4 ± 15.2 years, mean Na(+) level was 168.7 ± 7.4 mmol/L and, mean mortality was 49.5 % during the hospitalization. Multivariable Cox regression analysis showed that low systolic blood pressure, low pH, Na(+) >166 mmol/L, increased plasma osmolarity, mean sodium reduction rate ≤-0.134 mmol/L/h, dehydration, and, pneumonia to be independently associated with mortality. This study describes the demographic and clinical characteristics of patients with Na(+) >160 mmol/L in a large population along with comorbid conditions, incidence, treatment strategies and, its association with mortality.

RESUMO

In this study, we aimed to examine dynamic thiol/disulfide homeostasis in type 1 diabetes mellitus (T1DM) and identify the factors associated with thiol oxidation. Thirty-eight subjects (18 male, 20 female) diagnosed with T1DM and 38 (17 male, 21 female) healthy volunteers without any known diseases were included in the study. Thiol/disulfide homeostasis concentrations were measured by a newly developed method (Erel & Neselioglu) in this study. After native thiol, total thiol and disulfide levels were determined; measures such as disulfide/native thiol, disulfide/total thiol, and native thiol/total thiol were calculated. In T1DM patients, compared to the control group, disulfide (p = 0.024), disulfide/native thiol (p < 0.001), and disulfide/total thiol (p < 0.001) were determined higher, while native thiol (p = 0.004) and total thiol (p < 0.001) levels were much lower. In the patient group, a positive correlation was determined between c-reactive protein (r = 325, p = 0.007; r = 316, p = 0.010, respectively), fasting blood glucose (r = 279, p = 0.018; r = 251, p = 0.035, respectively), and glycosylated hemoglobin (r = 341, p = 0.004; r = 332, p = 0.005, respectively) and rates of disulfide/native thiol and disulfide/total thiol. We determined that thiol oxidation increase in T1DM patients compared to the control group. We thought that hyperglycemia and chronic inflammation might be the major cause of increase in oxide thiol form. In order to determine the relationship between the status of autoimmunity and dynamic thiol/disulfide in T1DM, dynamic thiol/disulfide homeostasis in newly diagnosed-antibody positive-T1DM patients is required to be investigated.

RESUMO

The aims of this study were to measure the levels of interleukin-33 (IL-33) and soluble Suppression of Tumorigenicity 2 (sST2) in patients with newly diagnosed primary hypertension (HT) and to determine the relationship between carotid intima-media thickness (CIMT) and IL-33/sST2. Eighty-two patients with newly diagnosed primary HT and ninety healthy volunteers were included in the study. CIMT ⩾0.9 mm was considered as significant for subclinical atherosclerosis. The sST2 levels of patients with primary HT were higher than those of the control group, whereas the IL-33 levels of these patients were much lower than those of the control group. The sST2 levels were higher in patients with subclinical atherosclerosis than in control subjects or patients with primary HT but not with subclinical atherosclerosis. In the primary HT group, sST2 had a positive correlation with CIMT, 24-h systolic-diastolic blood pressure, low-density lipoprotein and C-reactive protein, whereas sST2 had a negative correlation with the IL-33 level. A stepwise multivariable logistic regression analysis revealed that sST2 is an independent risk factor for subclinical atherosclerosis. Although the diagnostic predictive value of HT risk was determined as >51.8 pg l(-1) in the receiver operating characteristic curve analysis in respect of the sST2 level, the diagnostic predictive value for subclinical atherosclerosis risk was determined to be >107.2 pg l(-1). The sST2 level displays a positive correlation with atherosclerotic changes, and is an independent risk factor for subclinical atherosclerosis expressed as increased CIMT.

RESUMO

OBJECTIVE: Although several studies reported increased oxidative stress in Hashimoto's thyroiditis (HT), the effect of levothyroxine treatment on oxidative status is not studied extensively. Therefore, we conducted this study to investigate the effects of levothyroxine replacement on oxidative stress in HT. DESIGN AND METHODS: Thirty-six patients recently diagnosed with HT-related hypothyroidism and 36 healthy controls were included in the study. Levothyroxine replacement was started to patients with hypothyroidism, and had been followed-up for 6 months. RESULTS: Mean basal serum total antioxidant status (TAS), total thiol, arylesterase, and paraoxonase 1 (PON1) levels were significantly lower, and serum total oxidant status (TOS) and oxidative stress index (OSI) were significantly higher in the patients with hypothyroid than the controls. In the hypothyroid group serum TAS, total thiol, arylesterase, and PON1 levels increased and serum TOS and OSI levels decreased significantly after levothyroxine treatment. Pretreatment serum TAS, total thiol, PON1, and arylesterase levels were positively correlated with free levothyroxine (fT4) and negatively correlated with thyroid-stimulating hormone (TSH), antithyroid peroxidase (anti-TPO), and antithyroglobulin (anti-TG) levels. Also, pretreatment serum TOS and OSI levels were negatively correlated with fT4 levels and positively correlated with TSH, anti-TPO, and anti-TG. We have also found that the fT4 and anti-TPO levels are independent predictors of the oxidative stress parameters in stepwise multivariable linear regression analysis. CONCLUSION: This study suggests that levothyroxine replacement decreases oxidant status and increases antioxidant status following the 6 months of levothyroxine replacement in hypothyroidism that develops in accordance with the HT.

RESUMO

We aimed to investigate the thiol/disulphide homeostasis in patients with newly diagnosed primary hypertension with a novel and automated method. Blood thiol/disulphide homeostasis, which consists of native thiol/disulphide exchanges, was investigated in 45 patients with primary hypertension and 45 healthy controls. The levels of native thiol, total thiol, and native thiol/total thiol ratio were lower while the disulphide level and disulphide/native thiol and disulphide/total thiol ratios were higher in patients with primary hypertension when compared with those in the control group. Positive correlation was detected between 24-hour systolic and diastolic blood pressure levels and disulphide/native thiol ratio. With reference to the stepwise multiple linear regression model; increase in disulphide/native thiol ratio and log(24-hour urine microalbumin) and decrease in native thiol/total thiol ratio are independent predictors of 24-hour systolic and diastolic blood pressure. This study demonstrated that thiol/disulphide homeostasis was shifted toward disulphide formation in patients with primary hypertension.

RESUMO

Acute hepatitis is a disorder that goes with liver cell necrosis and liver inflammation. Among the causes of acute hepatitis, the most common reasons are viral hepatitis. About 95% of the acute hepatitis generate because of hepatotropic viruses. Epstein-barr virus (EBV) and cytomegalovirus (CMV) are from the family of herpes viruses and rare causes of acute hepatitis. In this case report, acute hepatitis due to EBV and CMV coinfection will be described. HOW TO CITE THIS ARTICLE: Ates I, Kaplan M, Yilmaz N, Çiftçi F.
