Öğe Alternative treatment of resistant hypoparathyroidism by intermittent infusion of teriparatide using an insulin pump: A case report(Baycinar Medical Publ-Baycinar Tibbi Yayincilik, 2019) Pekkolay, Zafer; Kilinc, Faruk; Soylu, Hikmet; Balsak, Belma; Guven, Mehmet; Tuzcu, Sadiye Altun; Kara, Ali VeyselHypoparathyroidism usually responds to oral active vitamin D and calcium, but, although rare, some patients do not respond to this treatment. A 47-year-old Caucasian female presented to our medical unit with classical oral treatment-resistant hypocalcemia after thyroidectomy. Teriparatide was infused through the insulin pump with dosage set to 1 unit which equals to 2.5 mu g of teriparatide. In conclusion, intermittent subcutaneous infusion of teriparatide using an insulin pump is a safe and effective treatment modality to ensure normocalcemic conditions in patients with classical treatment-resistant hypoparathyroidism.Öğe Could the appropriate anti-diabetic therapy be mixed insulin in dialysis patients?(Springer India, 2021) Demircan, Vehbi; Yildirim, Yasar; Aydin, Emre; Kara, Ali Veysel; Aydin, Fatma Yilmaz; Yilmaz, Zulfukar; Kadiroglu, Ali KemalBackground A good glycemic regulation should be provided to reduce mortality and morbidity in patients with end-stage renal failure due to diabetes mellitus. However, the use of insulin therapies in patients with renal failure is troublesome due to the increased rate of side effects. In our study, we investigated the frequency of hypoglycemia and its symptoms in patient groups receiving intensive and mixed insulin therapies. Materials and methods This prospective study included 89 hemodialysis patients with DM-related stage 5 chronic kidney disease who were followed up in a nephrology clinic of a university hospital between January 2013 and August 2015. Our study group was divided into two groups as those receiving intensive insulin therapy and mixed insulin therapy. Group 1 and group 2 consisted of 46 patients and 43 patients, respectively. Hypoglycemia (glucose < 70 mg/dl) was investigated in patients with HbA1c levels that decreased below 7% after treatment, and the symptoms were evaluated according to the hypoglycemic scale. The results between the groups were evaluated using chi-square and Student's t test Results A total of 89 patients were included in the study. HbA1c was 6.83% in the group receiving intensive insulin therapy and 6.95% in the group receiving mixed insulin therapy (p > 0.05). Hypoglycemia was detected in 27 patients (58.7%) in the intensive insulin therapy group and 14 patients (32.6%) in the mixed insulin therapy group. There was a significant level of hypoglycemia in the group receiving intensive insulin therapy (p < 0.05). In our study, the group receiving intensive insulin therapy had higher frequency and severity of common hypoglycemia symptoms such as confusion, sweating, weakness, dysphasia, palpitations, blurred vision, and feeling hungry. Conclusion There was a higher frequency of hypoglycemia under intensive insulin therapy in patients undergoing dialysis due to chronic kidney failure, which suggests that mixed insulin therapy is the ideal treatment to avoid hypoglycemia in this group of patients.Öğe Diyabetik Nefropati Progresyonunda Nt-Pro BNP ve Volüm Yükü Arasındaki İlişki(2016) Kara, Ali Veysel; Yıldırım, Yaşar; Yılmaz, Zülfükar; Yılmaz, Mehmet Emin; Güneş, Müslüm; Kadiroğlu, Ali KemalAmaç: Kronik böbrek hastalığında (KBH) volüm yükünün erken tanısı çok önemlidir. NT- Pro BNP bunu gösteren değerli bir biyomarkırdır. Çalışmamızda diyabetik nefropati zemininde KBH gelişen evre 3-4 hastalarda NT-Pro BNP'nin sol ventrikül hipertrofisi, kan basıncı, glomerüler filtrasyon hızı ve proteinüri ile ilişkisini değerlendirmeyi amaçladık. Yöntemler: Diyabetik nefropati zemininde kronik böbrek hastalığı gelişen evre 3, 80 hasta ile evre 4, 80 hasta çalışmaya dahil edildi. NT-Pro BNP serumda, proteinüri 24 saatlik idrarda çalışıldı. Hastaların M-Mode ekokardiyografi ile sol ventrikül hipertrofisi belirlendi. KBH evrelerine göre iki gruba ayrılan hastaların T Pro BNP değerleri, sol ventrikül hipertrofisi, hipertansiyon ve proteinüri ile karşılaştırıldı. Bulgular: Diyabetik nefropatide hastalığın progresyonu ile birlikte NT- Pro BNP anlamlı olarak artmaktaydı. Ancak NT Pro BNP, sol ventrikül hipertrofisi, yüksek kan basıncı 1gram/gün üzerinde proteinürisi olanlarda daha yüksekti. Bununla beraber NT- Pro BNP ile sol ventrikül duvar kalınlığı arasında da pozitif korelasyon vardı. Bağımsız değişken olarak proteinüri, sistolik ve diyatolik kan basıncı NT- Pro BNP artışı ile ilişkilidir. Sonuç: Kronik böbrek hastalığının progresyonu ile NT Pro BNP artmaktadır. Bu artışa en büyük katkıyı proteinüri yapmaktadır.Öğe Effect of intraperitoneal etanercept on oxidative stress in rats with peritonitis(Hindawi Ltd, 2016) Yıldırım, Yaşar; Cellad, Esma Gülsüm; Kara, Ali Veysel; Yilmaz, Zülfükar; Kadiroğlu, Ali Kemal; Bahadır, Mehmet Veysi; Gül, MesutOur aim was to evaluate effect of etanercept on oxidative stress parameters in rats with experimental peritonitis and investigate the availability of etanercept usage in the treatment of peritonitis in the future. Twenty-eight rats were divided into four groups as control (group 1), peritonitis (group 2), peritonitis + cefazolin sodium (group 3), and peritonitis + cefazolin sodium + etanercept (group 4). Peritoneal tissue and blood samples were taken from all of the rats for histopathological and biochemical examination. The oxidative stress parameters were examined in blood and tissue samples. It was observed that rats with peritonitis benefit from cefazolin sodium treatment. Evaluating the effectiveness of etanercept was our main objective for this study. In this perspective, we compared group 3 and group 4 and found statistically significant decreases in oxidative parameters and statistically significant increases in antioxidants in serum and tissue samples in group 4. It is observed that there was a significant contribution of etanercept on biochemical and also histopathological results. As a result, the TNF-alpha inhibitor, etanercept, in addition to antibiotics given in the early treatment of peritonitis results in more significant improvement of histopathological and oxidative parameters as compared to antibiotics alone.Öğe EFFECT OF RED CELL DISTRIBUTION WIDTH ON ACUTE KIDNEY INJURY IN PATIENTS WITH METASTATIC LUNG CANCER RDW IN LUNG CANCER PATIENTS WITH KIDNEY INJURY(Carbone Editore, 2019) Aydin, Fatma Yilmaz; Aydin, Emre; Yildirim, Yasar; Yilmaz, Zulfukar; Kara, Ali Veysel; Yilmaz, Sureyya; Kaplan, Muhammet AliIntroduction: Lung cancer is a common malignity with high mortality rate. One of the main reason which affects mortality is acute kidney injury (AKI). Therefore, early diagnosis of AKI is of essential. In our study, we investigated the effects of Red Cell Distribution Width (RDW) on acute kidney injury development in metastatic acute lung cancer patients. Material and methods : The present study was conducted 143 patients with lung malignity at Stage 4 followed up Faculty of Medicine, Dicle University, between 2010- 2015. The study was carried out retrospectively. Creatinine levels, RDW, hemoglobin, Mean Corpuscular Volume ( MCV), C Reaktive protein (CRP), albumin levels as of admission to the intensive care unit (ICU) and after 48 hours, length of stay in ICU and results were recorded. The patients were divided in two groups as RDW > 16,8 and <= 16,8. The groups were examined in terms of acute kidney injury development, mortality and length of stay in intensive care. Results: The study population consists of 122 male (85.3%) and 21 female (14.7%) patients. The average RDW values of the patients is 16.53 +/- 1.91 and RDW >16,8 in 43.4%. AKI development was identified in 60.1% of the patients. The mean age, serum creatinine, AKI and CRP, mortality values were significantly higher and serum albumin, length of stay in intensive care (day) were significantly lower in RDW> 16.8 patient group compared to RDW <= 16.8 patient group. Conclusion: The present study showed that RDW is closely associated with acute kidney injury in advanced lung cancer patients.Öğe Evaluation of Anthropometric and Metabolic Parameters in Obstructive Sleep Apnea(Hindawi Ltd, 2015) Yildirim, Yasar; Yilmaz, Sureyya; Guven, Mehmet; Kilinc, Faruk; Kara, Ali Veysel; Yilmaz, Zulfukar; Kirbas, GokhanAims. Sleep disorders have recently become a significant public health problem worldwide and have deleterious health consequences. Obstructive sleep apnea (OSA) is the most common type of sleep-related breathing disorders. We aimed to evaluate anthropometric measurements, glucose metabolism, and cortisol levels in patients with obstructive sleep apnea (OSA). Materials and Methods. A total of 50 patients with a body mass index >= 30 and major OSA symptoms were included in this study. Anthropometric measurements of the patients were recorded and blood samples were drawn for laboratory analysis. A 24-hour urine sample was also collected from each subject for measurement of 24-hour cortisol excretion. Patients were divided equally into 2 groups according to polysomnography results: control group with an apnea-hypopnea index (AHI) <5 (n = 25) and OSA group with an AHI = 5 (n = 25). Results. Neck and waist circumference, fasting plasma glucose, HbA1c, late-night serum cortisol, morning serum cortisol after 1 mg dexamethasone suppression test, and 24-hour urinary cortisol levels were significantly higher in OSA patients compared to control subjects. Newly diagnosed DM was more frequent in patients with OSA than control subjects (32% versus 8%, p = 0.034). There was a significant positive correlation between AHI and neck circumference, glucose, and latenight serum cortisol. Conclusions. Our study indicates that increased waist and neck circumferences constitute a risk for OSA regardless of obesity status. In addition, OSA has adverse effects on endocrine function and glucose metabolism.Öğe Evaluation of risk factors associated with epicardial fat tissue thickness in patients with stage 4 and stage 5 chronic kidney disease(Springer Science and Business Media B.V., 2025) İnce, Hasan; Yılmaz, Zülfükar; Karabulut, Aziz; Aydın, Emre; Yıldırım, Yaşar; Kara, Ali Veysel; Kadiroğlu, Ali KemalPurpose: Chronic kidney disease (CKD) is a global public health issue, often associated with high mortality and morbidity, especially due to cardiovascular diseases. Epicardial adipose tissue (EAT), the visceral fat surrounding the heart, has been recognized as a significant factor in cardiovascular risk. This study aims to assess the relationship between EAT and body composition in patients with stage 4 and 5 CKD using bioelectrical impedance analysis (BIA). Methods: The study included 80 patients with stage 4 and 5 CKD who were not on dialysis. Body composition was measured using BIA, and EAT was assessed using transthoracic echocardiography(ECHO). Exclusion criteria included heart failure, morbid obesity, pregnancy, and pacemaker use, among others. Various demographic, clinical, and biochemical parameters were also recorded. Results: Patients with stage 5 CKD (6.7 ± 0.12) had significantly higher EAT compared to stage 4 CKD (5.9 ± 0.09) patients. EAT showed a positive correlation with age, BMI, blood pressure, C-reactive protein (CRP), and triglyceride levels, and a negative correlation with albumin and HDL levels. Multivariate analysis revealed that increased systolic blood pressure(SBP)(p:0.019),fat tissue mass (FTM)(p < 0.001), low HDL(p: 0.027), and low albumin(p < 0.001) were independent predictors of EAT. Conclusion: EAT is higher in advanced CKD patients and is associated with several cardiovascular risk factors. Measuring EAT in CKD patients using non-invasive methods like ECHO could be valuable in predicting cardiovascular risks. Addressing the factors that contribute to increased EAT may improve clinical outcomes for CKD patients. © The Author(s), under exclusive licence to Springer Nature B.V. 2025.Öğe Evaluation of the effect of red cell distribution width on the development of acute renal failure in patients with sepsis(Dicle Üniversitesi Tıp Fakültesi, 2017) Kara, Ali Veysel; Tanrikulu, Sema; Aydın, Emre; Aydın, Fatma; Soylu, Hikmet; Yıldırım, Yaşar; Yılmaz, Zülfükar; Kadiroğlu, Ali Kemal; Yılmaz, Mehmet EminObjective: Acute kidney injury (AKI) is an important clinical entity that is known to increase mortality in patients with sepsis. Erythrocyte maturation and proliferation are inhibited by pro-inflammatory cytokines; these cytokines exert effects on red cell distribution width (RDW) well. Based on this knowledge; our aim in this study was to evaluate the impact of RDW on acute kidney injury in patients with sepsis. Methods: 120 patients diagnosed with sepsis and admitted to intesive care unit (ICU) and treated between 2009-2013 were retrospectively evaluated. Patients were divided into two groups as follows: group 1 (RDW≥16.8) and group 2 (RDW<16.8). Multiple logistic regression analysis was used to determine the association between RDW and AKI and mortality. Results: There was a statistically significant relationship between AKI and RDW (p<0.001, OR=11.52) but there were no statistically significant relationship between AKI and sex, age, serum lactate levels as well as SOFA score. Also, there were statistically significant relationship between mortality and RDW (p=0.044, OR=5), serum lactate levels (p=0.030) and SOFA score (p<0.001). RDW was found associated with both AKI and mortality. Conclusions: Results suggest that RDW is an important parameter for predicting development of AKI and mortality in ICU patients with sepsis.Öğe Pulmonary Function in Patients with End-Stage Renal Disease: Effects of Hemodialysis and Fluid Overload(Int Scientific Information, Inc, 2016) Yilmaz, Sureyya; Yildirim, Yasar; Yilmaz, Zulfukar; Kara, Ali Veysel; Taylan, Mahsuk; Demir, Melike; Coskunsel, MehmetBackground: Respiratory system disorders are one of the most prevalent complications in end-stage renal disease patients on hemodialysis. However, the pathogenesis of impaired pulmonary functions has not been completely elucidated in these patients. We designed a study to investigate acute effects of hemodialysis treatment on spirometry parameters, focusing on the relationship between pulmonary function and fluid status in hemodialysis patients. Material/Methods: We enrolled 54 hemodialysis patients in this study. Multifrequency bioimpedance analysis (BIA) was used to assess fluid status before and 30 min after the midweek of hemodialysis (HD). Overhydration (OH)/extracellular water (ECW)% ratio was used as an indicator of fluid status. Fluid overload was defined as OH/ECW 3 7%. Spirometry was performed before and after hemodialysis. Results: Forced vital capacity (FVC), FVC%, and forced expiratory volume in the first second (FEV1) levels were significantly increased after hemodialysis. FVC, FVC%, FEV1, FEV1%, mean forced expiratory flow between 25% and 75% of the FVC (FEF25-75), FEF25-75%, peak expiratory flow rate (PEFR), and PEFR% were significantly lower in patients with fluid overload than in those without. OH/ECW ratio was negatively correlated with FVC, FVC%, FEV1, FEV1%, FEF25-75, FEF25-75%, PEFR, and PEFR%. Stepwise multiple regression analysis revealed that male sex and increased ultrafiltration volume were independently associated with higher FVC, whereas increased age and OH/ECW ratio were independently associated with lower FVC. Conclusions: Fluid overload is closely associated with restrictive and obstructive respiratory abnormalities in HD patients. In addition, hemodialysis has a beneficial effect on pulmonary function tests, which may be due to reduction of volume overload.Öğe The relationship between acute kidney injury and inflammation-based parameters and mortality in oncologic intensive care patients(Turkish Society of Medical and Surgical Intensive Care, 2020) Aydın, Emre E.; Kadiroǧlu, Ali Kemal; Yilmaz Aydin, Fatma; Kara, Ali VeyselBackground and Aims: Cancer patients are admitted to intensive care units (ICU) due to primary diseases, treatment-related conditions or comorbid diseases. Acute kidney injury (AKI) and infections appear to be factors affecting mortality and morbidity in ICU follow-up. Therefore, in our study, we investigated the effect of AKI and inflammation-based parameters on mortality in cancer patients admitted to the ICU. Materials and Methods: In this study, 386 patients diagnosed with malignancy hospitalized between 2010 and 2014 in Dicle University Medical Faculty Internal Medicine ICU were included. The study was designed retrospectively. The demographic characteristics and clinical information of the patients were obtained from the files. Subsequently, patients were classified as non-survivors (group 1) and survivors (group 2). Both groups were compared in terms of the presence and stage of AKI by KDIGO definition, neutrophil / lymphocyte ratio (NLR) and platelet / lymphocyte ratio (PLR). Results: Creatinine, CRP, neutrophil counts were found to be significantly higher and albumin, hemoglobin, platelet and lymphocyte counts were found to be lower in group 1 (n=276) compared to group 2 (n=110). Length of ICU was longer in group 2 patients. There was a positive correlation between mortality and KDIGO stages and NLR. Mortality rate was increased 1.9 fold in KDIGO stage 1, 2.3 fold in stage 2, 2.4 fold in stage 3 and 1.5 fold if NLR>5. There was no statistically significant relationship between PLR and mortality. Conclusion: The presence of AKI and elevated inflammation-based parameters were associated with mortality in oncologic patients admitted to the ICU.Öğe The Relationship between Nt-ProBNP and volume overload in diabetic nephropathy progression(Dicle Üniversitesi Tıp Fakültesi, 2016) Yıldırım, Yaşar; Yılmaz, Zülfükar; Güneş, Müslüm; Kara, Ali Veysel; Kadiroğlu, Ali KemalObjectives: The early diagnosis of volume overload in chronic kidney disease (CKD) is very important. N-terminal probrain natriuretic peptide (NT-proBNP) is a valuable biomarker for this purpose. Our study aimed to detect the relationship between NT-proBNP and left ventricular hypertrophy (LVH), hypertension (HT), GFR, and proteinuria among diabetic patients with stage 3-4 CKD. Methods: 160 diabetic patients with stage 3-4 CKD [80 patients in stage 3 CKD (group 1) and 80 patients in stage 4 CKD (group 2)] were enrolled. NT-proBNP levels were evaluated in serum, and proteinuria was determined from 24-hour collected urine. Left ventricular hypertrophy was evaluated by M-mode echocardiography. NT-proBNP levels were compared according to their left ventricular hypertrophy, hypertension, and proteinuria levels. Results: NT-proBNP levels was significantly higher, and GFR was lower in group 2 compared to group1 (p < 0.05). NTproBNP was higher in patients with LVH (+) HT (+) and proteinuria ≥ 1gr/d than patients with LVH (-), HT (-), and proteinuria < 1g/d (p < 0.05). We found a significant correlation between NT-proBNP levels and left ventricular posterior wall thickness, diastole (LVPWTd), proteinuria, SBP, and DBP. Proteinuria was the major contributor to increased NTproBNP levels among the independent variables. Conclusion: We detected that NT-proBNP levels are increased during the progression of CKD, and proteinuria is the major cause of increased NT-proBNP levels among the independent variables.Öğe The relationship of fluid overload as assessed by bioelectrical impedance analysis with pulmonary arterial hypertension in hemodialysis patients(International Scientific Literature Inc., 2016) Yılmaz, Süreyya; Yıldırım, Yaşar; Taylan, Mahsuk; Demir, Melike; Yılmaz, Zülfükar; Kara, Ali Veysel; Aydın, Fatma; Şen, Hadice Selimoǧlu; Karabulut, Aziz; Topçu, FüsunBackground: Pulmonary arterial hypertension (PAH) is common disease among hemodialysis (HD) patients and is associated with increased morbidity and mortality. However, its pathogenesis has not been completely elucidated. We aimed to evaluate the frequency of PAH in HD patients, as well as the relationship between fluid status and PAH. Material/Methods: We enrolled 77 HD patients in this study. Multifrequency bioimpedance analysis (BIA) was used to assess fluid status. BIA was performed before and 30 min after the midweek of HD. Overhydration (OH)/extracellular water (ECW)% ratio was used as an indicator of fluid status. Fluid overload was defined as OH/ECW ?7%. Echocardiographic examinations were performed before and after the HD. Pulmonary arterial hypertension was defined as systolic pulmonary artery pressure at rest (sPAP) higher than 35 mmHg. Results: PAH was found in 33.7% of the HD patients. OH/ECW and the frequency of fluid overload were significantly higher in HD patients with PAH than those without PAH, whereas serum albumin and hemoglobin levels were significantly lower. sPAP level was significantly higher in HD patients with fluid overload than in those without fluid overload after hemodialysis session. Furthermore, sPAP, OH/ECW levels, and the frequency of PAH were significantly reduced after HD. We also found a significant positive correlation between sPAP and OH/ECW. Multivariate logistic regression analysis demonstrated fluid overload to be an independent predictor of PAH after HD. Conclusions: PAH is prevalent among HD patients. This study demonstrated a strong relationship between fluid overload and PAH in HD patients.
