Item Free Triiodothyronine in Hemodialysis Patients Link With Malnutrition and Inflammation(2014) Yavuz, Demet; Sezer, Siren; Yavuz, Rahman; Canoz, Mujdat Batur; Altinoglu, Alpaslan; Elsurer, Rengin; Arat, Zubeyde; Ozdemir, Fatma Nurhan; https://orcid.org/0000-0002-4082-6320; https://orcid.org/0000-0002-7326-8388; https://orcid.org/0000-0002-5682-0943; 24878944; ABG-9980-2021; JYQ-2550-2024; AAK-1697-2021Introduction. Free triiodothyronine (FT3) is a marker of comorbidity in end-stage renal disease and in many acute and chronic diseases. There is lack of data about the link between FT3 levels and malnutrition and inflammation in hemodialysis patients. The objective of the present study was to investigate the link between FT3 and malnutrition and inflammation in hemodialysis patients. Materials and Methods. A total of 84 patients were included in the study (38 men and 46 women; mean age, 56.2 +/- 14.8 years; hemodialysis duration, 95.72 +/- 10.35 months). Serum FT3, free thyroxin, and thyroid-stimulating hormone concentrations were determined. Demographic data and laboratory values were evaluated. Patients' comorbidity status was determined using the Charlson Comorbidity Index (CCI), and malnutrition-inflammation status was determined by Malnutrition-Inflammation Score (MIS). Results. Serum FT3 concentration inversely correlated with age (r = -0.328, P =.002), CCI (r = -0.591, P < .001), C-reactive protein (r = -0.299, P =.01), and MIS (r = -0.671, P < .001), and positively correlated with serum albumin (r = 0.389, P < .001). In multivariate linear regression analysis, FT3 was independently associated with MIS (beta, -0.14; 95% confidence interval, -0.175 to 0.063, P = .003), adjusted for CCI, C-reactive protein level, serum albumin level, and MIS. Conclusions. The results of this study indicate that FT3 is negatively correlated with inflammatory markers, namely C-reactive protein, and it is independently related with MIS in hemodialysis patients. Therefore, we suggest that FT3 can be accepted as an inflammatory marker in hemodialysis patients.Item Echocardiographic Epicardial Adipose Tissue Measurements Provide Information About Cardiovascular Risk in Hemodialysis Patients(2015) Ulusal Okyay, Gulay; Okyay, Kaan; Polattas Solak, Evsen; Sahinarslan, Asife; Pasaoglu, Ozge; Ayerden Ebinc, Fatma; Pasaoglu, Hatice; Boztepe Derici, Ulver; Sindel, Sukru; Arinsoy, Turgay; 0000-0001-6134-8826; 25643907; AAK-7355-2020Epicardial adipose tissue (EAT) is a cardiovascular risk predictor in general population. However, its value has not been well validated in maintainance hemodialysis (MHD) patients. We aimed to assess associations of EAT with cardiovascular risk predictors in nondiabetic MHD patients. In this cross-sectional study, we measured EAT thickness by transthoracic echocardiography in 50 MHD patients (45.8 +/- 14.6 years of age, 37 male). Antropometric measurements, bioimpedance analysis, left ventricular (LV) mass, carotis intima media thickness, blood tests, homeostasis model assessment for insulin resistance (HOMA-IR) and hemodialysis dose by single-pool urea clearence index (spKt/V) were determined. The mean EAT thickness was 3.28 +/- 1.04mm. There were significant associations of EAT with body mass index (=0.590, P<0.001), waist circumference (=0.572, P<0.001), body fat mass (=0.562, P<0.001), percentage of body fat mass (=0.408, P=0.003), percentage of lean tissue mass (=-0.421, P=0.002), LV mass (=0.426, P=0.002), carotis intima media thickness (=0.289, P=0.042), triglyceride/high-density lipoprotein cholesterol ratio (=0.529, P<0.001), 1/HOMA-IR (=-0.386, P=0.006), and spKt/V (=-0.311, P=0.028). No association was exhibited with visfatin C, high-sensitivity C-reactive protein, interleukin-6, and tumor necrosis factor-alpha (for all, P>0.05). Body mass index, waist circumference, body fat mass, percentage of lean tissue mass, LV mass, triglyceride/high-density lipoprotein cholesterol ratio, HOMA-IR, and spKt/V appeared as independent predictors of EAT. EAT was significantly associated with body fat measures, cardiovascular risk predictors, and dialysis dose in MHD patients.Item Management of Chronic Hepatitis in Special Hosts and Special Situations: A Consensus Report of the Study Group for Viral Hepatitis of the Turkish Society of Clinical Microbiology and Infectious Diseases(2014) Mistik, Resit; Aydin, Mehtap; Aksoy, Suleyman; Altin, Nilgun; Altunal, Nilsun; Avsar, Kemal; Bezirgan, Selma; Buke, Cagri; Celik, Ali Kutta; Celik, Ekrem; Dikici, Nebahat; Hizel, Kenan; Iskender, Serap; Kaya, Ali; Korkmaz, Fatime; Kose, Sukran; Sacligil, Cahide; Sirmatel, Fatma; Tarakci, Huseyin; Turgut, Huseyin; Tutuncu, Ediz; Yulugkural, Zerrin; https://orcid.org/0000-0003-4044-9366; HLX-0937-2023Study Group for Viral Hepatitis of the Turkish Society of Clinical Microbiology and Infectious Diseases convened a meeting to develop a consensus report on management of chronic hepatitis in special hosts and special situations.

Materials and Methods: The study involved 24 hemodialysis patients and 20 healthy volunteers. Light touch-pressure sensation (Semmes Weinstein Monofilament test kit), two-point discrimination sensation (esthesiometer) and vibration sensation (128 Hz diapason) were used to evaluate plantar foot sensation. Static balance was assessed by the one-leg standing balance test, physical performance by the Timed Up and Go test, fear of falling with the Fall Efficacy Scale, and quality of life with the Ferrans and Powers Quality of Life Index Dialysis Version. Findings: There was a significant difference in plantar foot sensation, static balance, and physical performance of the patients compared to the healthy controls (P < 0.05). There was a strong correlation between static balance and physical performance with foot sensation in the hemodialysis patients (P < 0.05). There was also a strong correlation between static balance, physical performance, and fear of falling in hemodialysis patients (P < 0.05). The correlation between static balance, physical performance, and quality of life in the hemodialysis patients was strong (P < 0.05). Discussion: The most important result of this study is that light touch-pressure sensation, vibration sensation, two-point discrimination sensation, static balance, and physical performance, all of which involve the activity of cutaneous sensory receptors on the sole of the foot, are reduced in individuals who undergo hemodialysis. The findings of this study suggest potential rehabilitation strategies that could be applied to this patient group.Item Fibromyalgia Syndrome in Turkish Hemodialysis Patients(2016) Leblebici, Berrin; Ozelsancak, Ruya; Yilmaz, Emine Ece; Doruk, Pinar; https://orcid.org/0000-0002-6241-268X; https://orcid.org/0000-0002-0788-8319; https://orcid.org/0000-0002-8602-6038; https://orcid.org/0000-0002-3528-3712; 26198740; AAM-3220-2021; AAD-5716-2021; AAA-8043-2021The aim of our study was to evaluate the frequency of fibromyalgia syndrome (FMS) in hemodialysis (HD) patients and to assess whether this syndrome is associated with gender, age, duration of HD, or various laboratory parameters. This study was composed of 221 chronic HD patients (99 females and 122 males), and we recorded each participant's age, gender, causes of kidney failure, HD duration, education level, and symptoms related to FMS, which was diagnosed according to the 2010 American College of Rheumatology criteria. We documented the laboratory parameters for all patients. In addition, patients with FMS filled out the Fibromyalgia Impact Questionnaire. Twenty-two patients met the diagnostic criteria for FMS (9%), and there were no statistically significant differences related to age, gender, or HD duration between FMS and non-FMS groups (P>0.05). In addition, the education levels were lower in patients diagnosed with FMS (P<0.05), and there were statistically significant differences related to sleep disturbance, fatigue, and cognitive symptoms between the two groups (P<0.05) as well. However, their laboratory parameters were similar (P>0.05). There was a higher prevalence of FMS in HD patients than in the general population. Sleep disturbances, fatigue, education level, and cognitive symptoms were associated with FMS, but there was no correlation between the laboratory parameters and this condition.
