Objective: We aimed to compare the frequencies of stromal cell-derived factor-1 (SDF-1) 3'A and CXCR4 single-nucleotide polymorphisms (SNPs) and serum SDF-1 levels in patients with preeclampsia (PE).Methods: In total, 89 women with PE and 89 control women were included in the study. Genotyping was done by polymerase chain reaction-restriction fragment length polymorphism method. Enzyme-linked immunosorbent assay method was used to measure serum SDF-1 level.Results: For SDF-1 3'A SNP, the frequency of GA genotype, total number of GA and AA genotypes, and the A allele frequency was higher in PE patients than controls (p = 0.04, 0.023, and 0.029, respectively). For CXCR4 SNP, the frequency of CT genotype, total number of CT and TT genotypes, and the T allele frequency were higher in PE patients than controls (p = 0.04, 0.006, and 0.005, respectively). SDF-1 serum level was detected higher in preeclamptic women compared with controls (p = 0.001). In PE patients, there was no significant association between serum SDF-1 levels and genotypes of SDF-1 3'A SNP. SDF-1 level was significantly higher in patients bearing CXCR4 CT genotype than CC genotype (p = 0.001). Furthermore, SDF-1 levels in patients bearing CT+TT genotype were found higher than that of patients with CC genotypes (p = 0.001).Conclusion: Results of our study suggest that SDF-1 3'A and CXCR4 polymorphisms and elevated serum SDF-1 levels may have a role in the development of PE.

Background: Crimean-Congo Hemorrhagic Fever (CCHF) is a disease characterized by serious course, including acute viral fever, ecchymosis, thrombocytopenia, liver dysfunction and high rate of mortality. Hypoxia Inducible Factor-1α (HIF-1α) and Vascular Endothelial Growth Factor-A (VEGF-A) play an important role both in the inflammatory process and plasma leakage. The aim of this study was to define HIF-1α and VEGF-A serum levels obtained from CCHF patients and control group and to investigate whether these factors were correlated with the pathogenesis of this disease. Methods: Thirty cases younger than 17yr confirmed by RT-PCR and/or ELISA for CCHF were included in this study. Thirty age and sex matched healthy peoples were enrolled as controls. Blood samples collected from the patient and control groups. Serum levels of HIF-1α and VEGF-A were measured with ELISA. Results: Levels of HIF-1α and VEGF-A were statistically significantly increased in CCHF patients compared to the control group (P< 0.05). A significant positive correlation was found between the levels of HIF-1α and VEGF-A in the patient group (P< 0.01). The levels of ALT, AST, CK, aPTT, WBC and Thrombocyte count were significantly higher in the patients than in the control group (P< 0.001). A positive correlation was found among the levels of AST and CK from biochemical parameters and VEGF and HIF-1α in the patient group (P< 0.05) Conclusion: HIF-1α and VEGF-A might play an important role in CCHF pathogenesis.

OBJECTIVE: Tinnitus is described as a disturbing sound sensation in the absence of external stimulation. We aimed to investigate whether there is any relationship between severe chronic tinnitus and angiotensin-converting enzyme (ACE) I/D and a-adducin (ADD1) G460W gene polymorphisms. MATERIALS and METHODS: The patient group and control group consisted of 89 and 104 individuals, respectively. The evaluation of tinnitus was performed using the Strukturiertes Tinnitus-Interview (STI). The Tinnitus Handicap Inventory (THI) was used to evaluate the tinnitus severity. Polymerase chain reaction (PCR) and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) techniques were used for genotyping. RESULTS: With regard to the ACE I/D polymorphism, there was no significant difference in genotype and allele frequencies between the patient group and control group. However, a statistically significant difference was found in genotype (p<0.01) and allele frequencies (p=0.021) of the ADD1 G460W gene polymorphism. Combined genotype analysis showed that the ACE II /ADD1 GW genotype was statistically significantly higher in the patient group than in the control group (X2: 7.15, p=0.007). The odds ratio value of the GW genotype was 2.5 (95% CI=1.4-4.7) (p<0.01). CONCLUSION: Our results demonstrate an association between ADD1 G460W gene polymorphism and susceptibility to severe chronic tinnitus. It was found that the GW genotype increased the disease risk by 2.5-fold compared with other genotypes. This indicates that ADD1 G460W polymorphism could be an important factor in the pathophysiology of tinnitus. [ABSTRACT FROM AUTHOR]

Diabetes mellitus is a metabolic disease with a high incidence of morbidity and mortality lowering the quality of life with acute and chronic complications and it needs to be followed up and treated throughout the lifespan. Concordant with the frequency of DM and the increase in the length of life frequency of DNP is also increased. The I allele of the ACE I/D polymorphism, AGT M235T's T allele and ADD G460W's W allele presence are purported to present a predisposition to DNP. In our study we aimed to investigate the effect of the AGT M235T, ACE I /D and ADD 460W polymorphisms in the development of DNP in patients with diabetes mellitus. The study group consisted of 194 patients with Diabetic nephropathy and the control group contained 100 DM patients. In the diabetic group the DD genotype of the ACE I/D polymorphism was 54 (54.0%) and the D allele was 69.0% and in the nephropathy group II genotype of the ID were 78 (40.2%) and 51 (26.3%) and the I allele was 46.4 respectively and the presence of the I allele was associated with the presence of nephropathy. There was no significance between the genotypes in the presence of a coexistence of AGT M235T and ACE I /D polymorphisms between the groups the MD alleles (42%) demonstrated significance in the diabetic and the T/I alleles (28.1) demonstrated significance in the nephropathy group. In the ADD G640W polymorphism on its own, subjects having GG (77.3%) and WW (7.7%) genotypes (p=0.025) might have been predisposed to nephropathy however when in combination with the ACE I /D, the presence of the DD/GG (45%) in the diabetic group and the presence of the ID/GG (29.9%) and II/GG (19.6%) combination in the DNP group were statistically significant. The D/G (64%) alleles were significant in the diabetic and the I/G (36.6) alleles were significant in the DNP groups respectively. As a conclusion we think that the II-ID/GG genotype and the I/G alleles in the presence of the ACE-ADD combination and TT/ID genotype and T/I alleles in the ACE-AGT combination may be effective in the predisposition of the diabetic patients to nephropathy.

Background: The aim of this study was to evaluate whether neutrophil gelatinase-associated lipocalin (NGAL) and interleukin-18 (IL-18) predict renal disfunction in patients with familial Mediterranean fever (FMF). Methods: This prospective study consisted of 102 patients with FMF in attack-free period, and 40 matched healthy controls. Of the patients, nine were diagnosed as amyloidosis. The patients were divided into two groups according to eGFR as below 120 mL per minute and above 120 mL per minute. Also, patients were divided into three groups according to the degree of urinary albumin excretion as normoalbuminuric, microalbuminuric, and macroalbuminuric. The serum levels of IL-18 (sIL-18) and NGAL (sNGAL), and urinary levels of IL-18 (uIL-18) and NGAL (uNGAL) were measured by using ELISA kits. Results: The levels of sIL-18, sNGAL, uIL-18, and uNGAL were detected significantly higher in FMF patients, particularly in patients with amyloidosis, when compared to controls. sNGAL, uIL-18, and uNGAL were significantly higher in patients with eGFR < 120 mL per minute than in patients with eGFR ≥ 120 mL per minute. sNGAL, uIL-18, and uNGAL were correlated significantly with urinary albumin excretion, additionally, were inverse correlated with eGFR. The most remarkable findings of this study are of the higher values of sIL-18, sNGAL, uIL-18, and uNGAL in both normoalbuminuric FMF patients and patients with eGFR ≥ 120 mL per minute. Conclusions: The results of this study suggest that sIL-18, uIL-18, sNGAL, and uNGAL are reliable markers of early renal disfunction in FMF patients, and may let us take measures from the early stage of renal involvement.

Objective: There is no study about hypertensive response to exercise (HRE), which is a marker of unborn hypertension (HT), and red cell distribution width (RDW) association, in diabetic normotensive patients. So, we aimed to investigate any correlation among RDW and HRE in normotensive type 2 diabetic patients. Methods: Consecutive type 2 diabetic patients without history of HT and with normal blood pressure (BP) on ambulatory BP monitoring were included to the study. We divided the patients into two groups depending on their peak systolic BP on exercise; HRE (Group 1) or normal response to exercise (Group 2). Results: Data of 75 diabetic patients (51.9 ± 9.7) were analyzed (31 male (48%)). Their mean RDW was 13.11 ± 0.46. Patients with HRE were significantly older than patients without HRE. Smoking was more frequent in Group 2. Gender distribution and body mass index were similar between the groups. Else hemoglobin, hematocrit, red blood cell count and RDW values were not significantly different. Office systolic BP and diastolic BP, daytime and 24-h systolic BP were significantly higher in Group 1 but heart rate was similar between the groups. Conclusions: This study revealed that RDW do not differ between diabetic normotensive patients with HRE or not. [ABSTRACT FROM AUTHOR]

Introduction: Crimean-Congo hemorrhagic fever (CCHF) is a zoonotic viral disease with a high mortality rate. In clinical practice, we observed bradycardia in some pediatric patients with CCHF during the clinical course. So we aimed to report CCHF cases that presented bradycardia during the clinical course and the relation of bradycardia with the clinical findings and ribavirin therapy. Methods: Charts of all hospitalized pediatric CCHF patients were reviewed with respect to age, sex, history of tick bite or history of removing a tick, other risk factors for CCHF transmission, and interval between the tick bite and the onset of symptoms. Outcomes and clinical and laboratory findings and medications were recorded for each patient. We searched the patient records for information regarding the existence of bradycardia. Bradycardia was accepted as the heart rate 2 standard deviations (SD) lower than the suspected heart rate based on age. Results: Fifty-two patients (mean age 11.2±4.4 years, 31 female) were enrolled into the study. Bradycardia was seen in seven patients. Six patients with bradycardia were male and only one was female, and the mean age was 13.1±1.6 years. It was observed that male gender is frequent among patients with bradycardia, as compared with those without bradycardia ( p=0.01). Bleeding was found to be more frequent in patients with bradycardia ( p=0.02). There were significant differences between the bradycardia and nonbradycardia groups with regard to the requirements for fresh frozen plasma transfusion, the number of platelet suspension given, requirement for intravenous immune globulin (IVIG) and in the days of stay in hospital ( p=0.01, p=0.03, p=0.03, p=0.04, respectively). Conclusion: Reversible bradycardia might be seen in the clinical course of pediatric CCHF patients, and the clinicians must be aware of this finding. The possibility that ribavirin may potentiate bradycardia cannot be assessed without a placebo-control study. So further studies may help to reveal the cause of the bradycardia, the disease itself, or the ribavirin therapy. Hence this study supports the need for a randomized, placebo-controlled study to assess intravenous ribavirin in treating CCHF and to support approval of the drug. [ABSTRACT FROM AUTHOR]

Background. The purpose of the present study is to determine the association between neutrophil/lymphocyte ratio and both subclinical inflammation and amyloidosis in familial Mediterranean fever. Methods. Ninety-four patients with familial Mediterranean fever and 60 healthy volunteers were included in the study. Of the patients, 12 had familial Mediterranean fever related amyloidosis. The neutrophil/lymphocyte ratio of the patients was obtained from the hematology laboratory archive. Results. The neutrophil/lymphocyte ratio was significantly higher among persons with familial Mediterranean fever compared to healthy individuals (P < 0.0001). Also, neutrophil/lymphocyte ratio was significantly higher in patients with amyloidosis than in amyloidosis-free patients (P < 0.0001). Since NLR was evaluated in nonamyloid and amyloid stages of the same patient population (type 1 phenotype), we obtained significant statistical differences (1.95 ± 0.30 versus 2.64 ± 0.48, P < 0.05, resp.). With the cutoff value of neutrophil/lymphocyte ratio >2.21 and AUC = 0.734 (P = 0.009), it was a reliable marker in predicting the development of amyloidosis. Conclusion. The neutrophil/lymphocyte ratio, an emerging marker of inflammation, is higher in patients with familial Mediterranean fever in attack-free periods. The neutrophil/lymphocyte ratio may be a useful marker in predicting the development of amyloidosis. [ABSTRACT FROM AUTHOR]

Abstract: The aim of this study was to investigate the morphological changes of the hippocampus after orchiectomy and the protective effects of testosterone on these changes. Animals were divided into 3 groups. The rats in group I were used for sham-orchiectomy. Orchiectomy was performed on the rats in group II. The rats in group III were administrated testosterone propionate 0.5mg/kg/day for 30 days after the orchiectomy. Some of the hippocampal tissues were used for determination of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) enzyme activities, and malondialdehyde (MDA) levels. The remaining hippocampal tissue specimens were stained with routine histological methods and examined under the light microscope. Additionally, the samples were immunohistochemically stained by using avidin–biotin-peroxidase for determination of bax immunoreactivity. The SOD and GSH-Px enzyme activities of the hippocampus were decreased, and MDA levels were increased in group II rats compared to the sham-orchiectomy group. In the light microscopic evaluation of the tissue specimens from group II, significant increases were detected in the number of picnotic cells and in bax immunoreactivity compared to the sham-orchiectomy group. However, an increase was observed in activities of SOD and GSH-Px enzymes and a decrease of the MDA levels in animals with orchiectomy, but having externally administered testosterone. It was determined that the increase of bax immunoreactivity and histopathological changes in this group were regressed by testosterone. The results of our study revealed that orchiectomy-induced oxidative damage and morphological changes in the hippocampal tissue were suppressed by testosterone. [ABSTRACT FROM AUTHOR]
