Yayın The association of endoplasmic reticulum aminopeptidase-1 (ERAP-1) with Familial Mediterranean Fever (FMF)(SAGE PUBLICATIONS INC, 2016) Sezgin, Gulbuz; Dabak, Resat; Kaya, Fatih Oner; Kotevoglu, Nurdan; Uygur-Bayramicli, Oya; Nalbant, SelimBackground: The ERAP1 gene cleaves the receptors and reduces their ability to transmit chemical signals to the cell that affect the process of inflammation and, secondly, it cleaves many types of proteins into small peptides that are recognized by the immune system. Objective: ERAP-1 gene mutations may create a sensitivity for Familial Mediterranean Fever (FMF). Method: We included 15 FMF patients with the M694 (+) mutation in the study in order to exclude patients without pyrin gene mutations and create a homogeneous study group. Fifteen patients with ulcerative colitis formed the control group. Results: There wasn't any case without ERAP-1 gene mutations. At least one mutation at exon 3 or exon 10 was found in all cases in both groups. There were 14 ERAP-1 gene mutations at exon 10 and 11 at exon 3 in patients with FMF. Interestingly, if there were ERAP-1 gene mutations at exon 3, a p.Arg127 Pro (c.380G>C) mutation always existed for three FMF patients with polymorphic mutations at this exon. There were 11 ERAP-1 gene mutations at exon 10 and 12 gene mutations at exon 3 in patients with ulcerative colitis. Exon 3 mutations were usually single p.Arg127 Pro (c.380G>C) mutations for 12 patients with ulcerative colitis as seen in the patients with FMF. The single mutation was always p.Ser453 Ser (c.1359T>C) for patients with ulcerative colitis at exon 10. Conclusion: There are more ERAP-1 mutations in the FMF group in comparison to the ulcerative colitis group. So, there may be a strong susceptibility to ERAP-1 gene mutations in FMF patients according to our results. However, further studies with larger study and control groups are needed.Yayın LONG TERM FOLLOW-UP OF FIVE PATIENTS WITH ACUTE INTERMITTENT PORPHYRIA, CASE BASED CLINICAL STUDY(NOBEL ILAC, 2016) Sezgin, GulbuzPorphyrias are among rare group of inherited diseases emerging due to decreased enzymes which have the role of the biosynthesis of the hem. The most common and the most serious form is acute intermittent porphyria (AIP) which is an autosomal dominant disease. Gastrointestinal and neuropsychiatric symptoms can be seen at the patients. Five cases who had been followed 2-23 years after the diagnosis, were presented in this paper. Three cases were brothers, one case was father and daughter, and the other case was a male from different family. Symptoms were first seen between ages 15-39. Two cases showed long and severe attacks which were characterized by symptoms of the autonomic and peripheral nervous system. Abdominal pain for other three cases and neurologic signs for the fifth case were distinctive. Porphobilinogen, protoporphyrin and aminolevulinic acide were high in the urine of every patient. All patients were provided benefits from intravenous hem treatment. Second case was deceased on 19th year of the follow-up, due to multi organ failure after myocardial infarction. As a conclusion; even though porphyria is an easily diagnosable disease, main problem is that there is little knowable and little awareness of the disease. Patients can apply with different clinical appearance and it is interesting that the disease is highly sensitive to the environmental factors and comorbidities.Yayın Melatonin with 1,25-Dihydroxyvitamin D3 Protects against Apoptotic Ischemia-Reperfusion Injury in the Rat Kidney(INFORMA HEALTHCARE, 2012) Sinanoglu, Orhun; Sezgin, Gulbuz; Ozturk, Guler; Tuncdemir, Matem; Guney, Sevin; Aksungar, Fehime Benli; Yener, NeseThis study was designed to evaluate the preventive role of melatonin (Mel) and 1,25-dihydroxyvitamin D3 (VD3) in biochemical and apoptotic events leading to tissue injury and renal dysfunction after ischemia-reperfusion (I/R). Thirty male Wistar rats were divided into five groups: sham-operated, I/R, Mel + I/R, VD3 + I/R, and Mel + VD3 + I/R. The rats were intraperitoneally administered with Mel (10 mg/kg), VD3 (0.5 mu g/kg), or Mel (10 mg/kg) plus VD3 (0.5 mu g/kg) each day at 1 week prior to ischemia. Right nephrectomy was initially performed and left renal I/R injury was induced by 45 min of bilateral renal ischemia followed by 45 min of reperfusion. After reperfusion, kidneys and blood were obtained for histopathologic and biochemical evaluation. Mel and VD3 had an ameliorative effect on biochemical parameters such as serum creatinine, blood urea nitrogen, alanine aminotransferase, aspartate aminotransferase, and apoptosis (caspase-3 and terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling staining) in the kidneys against renal I/R injury in rats. Additionally, VD3 combined with Mel significantly reduced apoptotic and histological alterations when compared with Mel or VD3 alone. This preventive effect on renal tubular apoptosis was remarkable when Mel was combined with VD3.Yayın The prevalence and risk factors for urinary incontinence among inpatients, a multicenter study from Turkey(ScienceDirect, 2020) Savas, Sumru; Saka, Bulent; Akin, Sibel; Tasci, Ilker; Tasar, Pinar Tosun; Tufan, Aslı; Yavuzer, Hakan; Balci, Cafer; Sezgin, Gulbuz; Karan, Mehmet Akif; Kocak, Fatma Ozge Kayhan; Ozturk, Zeynel Abidin; Varli, Murat; Erdincler, Deniz Suna; Esme, Mert; Nalbant, Selim; Cankurtaran, Mustafa; Ozer, Firuzan Firat; Atli, Teslime; Akcicek, FehmiObjective: To determine the prevalence and the factors associated with urinary incontinence (UI) among inpatients in Turkey. Method: The population of this study comprised of patients screened by the National Prevalence Measurement of Quality of Care (LPZ) study in 2017 and 2018. Age, gender, comorbidities, length of hospital stay, sedative medications, SARC-F score, anthropometric measurements, and care parameters such as malnutrition, falls, UI-fecal incontinence (FI), restraints, and care dependency score (CDS) were noted. The LPZ questionnaire was performed by trained researchers, and multiple logistic regression analysis was performed to determine the factors associated with UI. Results: The prevalence of UI was 29.4 % among 1176 inpatients, and 41.6 % in patients >= 65 years. Urinary incontinence was associated with older age (OR, 1.966, 95 % CI 1.330-2.905), female sex (OR, 2.055, 95 % CI 1.393-3.030), CDS (OR, 3.236, 95 % CI 2.080-5.035), the number of comorbidities (OR, 1.312, 95 % CI 1.106-1.556), end-of life management (OR, 3.156, 95 % CI 1.412-7.052), sedative medications (OR, 1.981, 95 % CI 1.230-3.191), and FI (OR, 12.533, 95 % CI 4.892-32.112) in all adults, where CDS (OR, 2.589, 95% CI 1.458-4.599), end-of life management (OR, 2.851, 95 % CI 1.095-7.424), sedative medications (OR, 2.529, 95 % CI 1.406-4.548), and FI (OR, 13.138, 95 % CI 4.352-39.661) were associated with UI among geriatric patients. Conclusions: The factors associated with UI in geriatric and all adult inpatients are CDS, sedative medications, end-of life management, and FI plus older age, female sex, and comorbidities for the latter. The factors associated with UI vary in different age groups.Yayın Protective Effect of Melatonin and 1,25-Dihydroxyvitamin D3 on Renal Ischemia-Reperfusion Injury in Rats(INFORMA HEALTHCARE, 2013) Sezgin, Gulbuz; Ozturk, Guler; Guney, Sevin; Sinanoglu, Orhun; Tuncdemir, MatemIschemia-reperfusion (I/R) injury induces the generation of reactive oxygen species (ROS) which affect many organs. This study was designed to investigate the roles of melatonin and 1,25-dihydroxyvitamin D-3 (VD3) on renal I/R injury. Thirty male Wistar albino rats were divided into five groups: group 1, control; group 2, right nephrectomy (RN) + I/R in the contralateral kidney; group 3, melatonin + RN + I/R; group 4, VD3 + RN + I/R; and group 5, melatonin + VD3 + RN + I/R. Melatonin (10 mg/kg), VD3 (0.5 mu g/kg), and melatonin plus VD3 were injected intraperitoneally for 7 days before renal I/R. After 7 days, right nephrectomy was initially performed and left renal artery was clamped for 45 min. After 45-min reperfusion, the serum and kidney tissue samples were obtained for assays. Melatonin and VD3 had an ameliorative effect on biochemical parameters such as serum creatinine (SCr) and blood urea nitrogen (BUN). Renal tissue malondialdehyde (MDA), glutathione (GSH), nitric oxide (NO) levels, and superoxide dismutase (SOD) activity were determined. Renal I/R decreased the kidney tissue GSH levels and SOD activity and increased the NO levels as compared with control group. However, melatonin and VD3 and melatonin plus VD3 treatment significantly increased the tissue GSH levels and SOD activity and decreased the NO levels compared with those of I/R group. Meanwhile, MDA levels were not different between the control and I/R groups. But, MDA levels decreased in all treated groups compared to I/R and control groups. These data support that melatonin and VD3 have beneficial effects on renal injury.Yayın St. John's wort (Hypericum perforatum) and warfarin: Dangerous liaisons!(TURKISH SOC GASTROENTEROLOGY, 2011) Bayramicli, Oya Uygur; Kalkay, Mehmet Nuri; Bozkaya, Evrim Oskay; Kose, Evrim Dogan; Iyigun, Ozgun; Goruk, Mucahit; Sezgin, Gulbuz…Yayın VITAMIN D LEVELS OF OUTPATIENTS ADMITTED TO A UNIVERSITY HOSPITAL IN THE MARMARA REGION OF TURKEY OVER 3 YEARS(DE GRUYTER POLAND SP ZOO, 2019) Sezgin, Gulbuz; Ozturk, Guler; Turkal, Rana; Caykara, BurcuBackground: Vitamin D regulates calcium and phosphorus metabolism, and it is essential for bone formation. Several factors can affect vitamin D levels in plasma. In present study we compare vitamin D levels of outpatients, who admit to Maltepe University Hospital between 2011 and 2013 and had vitamin D measurements regarding gender, age, and season. Methods: Hospital records were evaluated to identify the outpatients with vitamin D levels and their gender, age, and vitamin D levels and the seasons of measurements were recorded. Results: Data of 4860 subjects (74% female) were analyzed and 69.2% were between 18-64 years old. Vitamin D levels were as follows: 43.1% <= 10 ng/mL, 31.9% between 10 ng/mL and 20 ng/mL, 16.1% between 20 ng/mL and 30 ng/mL, and only 8.9% >= 30 ng/mL. The number of females with vitamin D levels < 10 ng/mL was significantly higher than that of males, while the number of males with vitamin D levels between 10 ng/mL and 20 ng/mL was significantly higher than that of females (P = 0.001) for each of the individuals, 6.2% and 11.1% had sufficient levels in winter and summer, respectively. Overall, it was observed that 6.6% of individuals between 18-44 years old, 8.2% of individuals between 45-64 years old and 10.3% of individuals over 65 years old had vitamin D levels > 30 ng/mL. Conclusions: The prevalence of vitamin D deficiency in outpatients of Maltepe University Hospital in Marmara region was 75% (< 20 ng/mL).
