ABSTRACT: The aim of this study was to determine the rate of MEFV gene mutations, the gene responsible for familial Mediterranean fever (FMF), in patients with hematolymphoid neoplasm. The rate of the five most common MEFV gene mutations (M694V, M680I, V726A, M694I and E148Q) was determined in 46 patients with hematolymphoid neoplasm. We found a high frequency of carriers in patients with multiple myeloma (60%) and acute lymphocytic leukaemia (33.3%), whereas patients with chronic lymphocytic leukaemia (9%) and non-Hodgkin lymphoma (5%) had a low mutation carrier rate. There is no MEFV gene mutation in patients with Hodgkin lymphoma. Furthermore, the statistically significant predominance of strong heterozygous mutations such as M694V and M680I in patients with hematolymphoid neoplasm; none had own and/or family history compatible with FMF, is interesting. In conclusion, we found a high frequency of carriers for MEFV gene in patients with multiple myeloma and acute lymphocytic leukaemia. The data of our study may provide some new insights in understanding of individual genetic differences in susceptibility to these neoplasms.

ABSTRACT: To investigate the association of plasma osteoprotegerin (OPG) levels with diabetic neuropathy.
Forty-two diabetic patients (21 female and 21 male) and twenty-four non-diabetic healthy control subjects (12 female and 12 male) were included in the study. All consecutive diabetic patients who came for routine follow-up at our outpatient clinic were invited to participate in this clinical study. We studied EMG and neuropathy symptom score in all study subjects. Fasting plasma glucose, HbA1 C, hs-CRP, OPG levels and lipid profile were measured for each subject.
Serum fasting glucose, HbA1c, HOMA-IR, total cholesterol, triglyserid, LDL-Cholesterol, HDL-Cholesterol, lipoprotein (a), apolipoprotein-b, hs-CRP, OPG levels, and neuropathy symptom score were statistically higher in diabetic patients than in healthy control subjects. Plasma OPG levels was statistically higher in diabetic patients than it was in nondiabetic control subjects. However, plasma OPG levels were not significantly different between diabetic patients without neuropathy and healthy control subjects. On the other hand, OPG levels were statistically higher in diabetic patients with neuropathy than in patients without neuropathy. In addition to that serum fasting glucose, HbA1c, hs-CRP, diabetes duration, neuropathy symptom score were statistically higher in diabetic patients with neuropathy than they were in patients without neuropathy. In total group of subjects, plasma OPG levels were correlated significantly with age, diabetes duration, HbA1c, total cholesterol, HDL-cholesterol, lipoprotein (a), apolipoprotein b, hs-CRP. In diabetic patients, plasma OPG correlated significantly with age, diabetes duration, neuropathy symptom score, HbA1c, lipoprotein (a), apolipoprotein b levels.
The major findings of this study were that the plasma OPG concentrations were higher in type 2 diabetic patients than OPG concentrations in healthy control subjects and they were positively correlated with diabetic neuropathy. This finding supports the growing concept that OPG acts as an important regulator in the development of vascular dysfunction in diabetes.

ABSTRACT: The rationale of this study is based on the fact that, both proteinuria and elevated asymmetric dimethyl arginine (ADMA) levels have been linked to the progression of vascular disease. Currently, there is not enough knowledge about any association between the levels of proteinuria and ADMA levels. Seventy-eight non-diabetic patients (42 men, 36 women, mean age of 26.1+/-5.2 years) with proteinuria having normal glomerular filtration rate were enrolled along with 38 healthy subjects (20 men, 18 women, mean age of 26.9+/-5.9 years). Proteinuria was below 3.5 g/day in 40 patients and above 3.5 g/day in 38 patients. Both groups had similar age, gender, and body mass index distributions. Serum ADMA, symmetric dimethyl arginine (SDMA), immunoreactive insulin, and high sensitivity C reactive protein (hsCRP) levels were measured. Insulin resistance was determined by homeostasis model assessment (HOMA). Serum ADMA, SDMA, insulin, hsCRP levels, and HOMA indexes were significantly higher in patients than in healthy control subjects. The above parameters were higher in the nephrotic range proteinuria group when compared to patients having protein levels below 3.5 g/day. There were significant correlations between the levels of proteinuria and the above parameters. According to the regression analysis, levels of proteinuria and hsCRP were significant determinants of serum ADMA levels. Our results indicate that, independent of other risk factors, ADMA is directly associated with proteinuria. Further studies are recommended to find out whether elevated ADMA levels are implicated in the high cardiovascular risk of proteinuric nephropathies.

ABSTRACT: Tuberculosis is an opportunistic infection that carries substantial morbidity and mortality in renal transplant recipients. We report here about a 21 year-old man with a living related renal transplant from his mother who developed persistent extra-pulmonary tuberculosis. The disease showed aggressive invasion to the axillary and mediastinal regions with abscess formations, despite standard antituberculosis treatment. During the course of the disease, immunosuppressive therapy was stopped, and the patient received extraordinary doses of multiple antituberculosis drugs. The patient then showed an uneventful course with good clinical and radiological responses.

ABSTRACT: The aim of the present study was to explore the relationship between tissue levels of leptin, soluble interleukin-6 receptor (sIL-6R), high-sensitive-C-reactive protein (hs-CRP) and soluble vascular cell adhesion molecule-1 (sVCAM-1) in atherosclerotic plaques, and traditional risk factors. Coronary artery specimens were obtained from 35 consecutive patients (26 men and nine women) who underwent coronary artery bypass grafting procedure. The mean tissue levels of leptin, hs-CRP and sIL-6R were significantly higher in patients with diabetes mellitus than without diabetes mellitus. When patients were classified according to the smoking status, the mean tissue levels of leptin, hs-CRP and sIL-6R were significantly higher in current smokers than both former smokers and non-smokers. In addition, the mean tissue levels of leptin and sIL-6R were significantly higher in former smokers than non-smokers. There was a positive association between leptin and hs-CRP, sIL-6R and plasma glucose in all patients. Plasma HDL levels were associated negatively with atherosclerotic tissue levels of leptin. Tissue levels of sIL-6R were associated significantly in a positive manner with leptin, hs-CRP and plasma glucose, while tissue levels of hs-CRP were associated with both leptin and sIL-6R. In conclusion, it is attractive to speculate that hs-CRP, sIL-6R and leptin could act synergistically in course of local inflammatory activity and those molecules may not be just markers of inflammation and cardiovascular risk but are also likely to play a pathogenic role in atheromatous plaque. In addition, atherosclerotic tissue levels of CRP, sIL-6R and leptin were significantly higher in current smokers and patients with diabetes.

ABSTRACT: Although some information is available regarding immune activation in familial Mediterranean fever (FMF), little is known about either peripheral blood T cell activation marker expression or the T cell proliferative response to phytohaemagglutinin (PHA). In the present study, we aimed to investigate the percentages of peripheral blood lymphocyte subsets, T cell expression of cellular activation markers (CD25, CD69, HLA-DR), the T cell response to PHA and serum levels of soluble interleukin-2 receptor (sIL-2R) and interleukin (IL)-10 in patients with FMF. Forty patients with FMF were enrolled into the study. Control groups were sex- and age-matched and consisted of 20 healthy blood donors and 15 patients with inactive Behcet's disease. The patients with FMF in an attack period had higher levels of sIL-2R than those in an attack-free period, and also in comparison with both control groups. The levels of sIL-2R were also found to be higher in patients with FMF in an attack-free period than those in both control groups. The mean levels of IL-10 were found to be lower in patients with FMF in an attack-free period than those in an attack period and were also lower than those in the healthy controls. In an acute attack period, the absolute counts of CD3+HLA-DR+, CD4+CD69+, CD8+CD25+ and CD8+CD69+ T cells in peripheral blood samples were also higher than those in both control groups. Both the percentages and absolute counts of CD4+CD69+ T cells in peripheral blood samples of patients with FMF in an attack-free period were slightly but significantly higher than those in the healthy controls. In conclusion, our study indicates that the T cell system is abnormally activated in patients with FMF in both the attack and attack-free period and that decreased IL-10 levels may create a tendency to perpetuate subclinical immune activation in the attack-free period.

ABSTRACT: The main objective of the present study was to examine the alterations in plasma total homocysteine (tHcy) concentrations during a testosterone-deficient state and after gonadotropin treatment for 6 Months in patients with idiopathic hypogonadotropic hypogonadism (IHH). Thirty-five newly diagnosed male patients with IHH (mean age 21.34+/-1.53 years) and 29 age- and body mass index-matched healthy males (mean age 21.52+/-1.77 years) were recruited into the study. Pretreatment levels of free testosterone (1.51+/-0.66 pg/ml), estradiol (21.37+/- 4.37 pg/ml), FSH (0.91+/-0.24 IU/l) and LH (1.25+/- 0.53 IU/l) were lower than controls (25.17+/-3.06 pg/ml, 31.00+/-4.96 pg/ml, 3.14+/-1.62 IU/l and 4.83+/-1.65 IU/l respectively) (P<0.001). They increased significantly after treatment (18.18+/-1.59 pg/ml, 27.97+/- 4.25 pg/ml, 2.41+/-0.27 IU/l and 2.79+/-0.19 IU/l respectively) (P<0.001). Patients with IHH had lower tHcy levels than controls (10.14+/-1.34 and 12.58+/- 2.29 micro mol/l respectively) (P<0.001). Plasma tHcy concentrations increased significantly (12.63+/-1.44 micromol/l) after 6 months of treatment (P<0.001). As compared with the controls, pretreatment levels of serum creatinine (63.54+/-13.01 vs 82.84+/-16.69 micromol/l), hemoglobin (12.98+/-0.56 vs 13.83+/-0.71 g/dl) and hematocrit (39.29+/-2.01 vs 41.38+/-1.95%) were significantly lower (P<0.001), and they increased significantly following treatment (80.24+/-11.93 micromol/l, 13.75+/-0.49 g/dl and 41.26+/-1.78% respectively) (P<0.001). The pretreatment folic acid and vitamin B(12) levels were significantly higher in patients when compared with controls (14.87+/-5.68 vs 12.52+/-4.98 nmol/l, P=0.034 and 289.75+/-92.34 vs 237.59+/-108.17 pmol/l, P=0.002 respectively). They decreased significantly after treatment (11.29+/-3.31 nmol/l and 228.51+/-54.33 pmol/l respectively) (P<0.001). The univariate and multivariate regression analysis results showed that only changes in creatinine, creatinine clearance, vitamin B12 and folic acid were independently associated with changes in tHcy levels in patients with IHH. In conclusion, the increase in plasma tHcy concentrations following gonadotropin treatment seems to be largely independent of changes in androgen levels.

ABSTRACT: A previous study reported that the midnight-to-morning urinary cortisol increment method could be used to reliably assess the insufficiency of the hypothalamic-pituitary-adrenal (HPA) axis. The principal aim of the present study is to verify whether the midnight-to-morning urinary cortisol increment is a reliable method for the assessment of the HPA axis in patients with various degrees of impaired kidney function. Fifty-six clinically stable patients with chronic kidney disease (CKD) and 14 healthy subjects were enrolled in the present study. Patients with CKD were divided on the basis of glomerular filtration rate (GFR) into the following arbitrary groups: mild (GFR: 60-89 ml/min/1.73 m2, no.=15), moderate (GFR: 30-59 ml/min/1.73 m2, no.=12) and severe kidney insufficiency (GFR: 15-29 ml/min/1.73 m2, no.=13), and hemodialysis patients. Plasma cortisol and ACTH levels were measured. The HPA axis was assessed by short Synacthen test and overnight dexamethasone suppression test. Double voided urine samples were collected at midnight and waking in the patients and the controls. Urinary free cortisol (UFC) and creatinine levels were measured and the UFC/creatinine ratio (Cort/Cr) was calculated. Then, the Cort/Cr increment was calculated as the morning Cort/Cr minus the midnight Cort/Cr. Baseline plasma cortisol levels were not significantly different between two groups. However, we found that CKD patients had significantly greater plasma ACTH levels than controls. The patients with CKD had also significantly lower morning UFC levels than controls and there was a progressive fall in morning UFC levels with decreasing GFR. The assessment of the HPA axis in patients with GFR lower than 29 ml/min was hampered by falsely abnormal responses to the midnight-to-morning urinary cortisol increment method. Plasma cortisol responded normally to exogenously administered ACTH, while plasma cortisol was suppressed by overnight dexamethasone administration in all patients with CKD. In conclusion, this method is not a reliable test for assessment of the HPA insufficiency in patients with GFR lower than 29 ml/min.

ABSTRACT: In the present study, we aimed to investigate the effects of testosterone deficiency and gonadotropin therapy on the in vitro production of tumour necrosis factor-alpha (TNF-alpha) and interleukin-1beta (IL-1beta) by peripheral blood mononuclear cells (PBMCs) from patients with idiopathic hypogonadotropic hypogonadism (IHH) in order to elucidate the modulatory role of androgen in cytokine production. Fifteen male patients with untreated IHH and 15 age-matched healthy male subjects were enrolled in the study. Serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), free testosterone (FT), sex hormone binding globulin (SHBG), prolactin, and IL-2 and IL-4 levels were also measured. In unstimulated cultures, IL-1beta and TNF-alpha secretion were not significantly different between patient and control groups. However, after stimulation with lipopolysaccharide (LPS), secretion of IL-1beta and TNF-alpha was significantly higher in cultures from untreated patients with IHH than in control subjects. Mean FSH, LH and FT levels were significantly lower, whereas SHBG, IL-2 and IL-4 levels were significantly higher in patients with IHH compared than in controls. In patients with IHH, FT negatively affected the serum levels of IL-4 and in vitro secretion of IL-1beta and TNF-alpha. In addition, IL-2 and IL-4 affected the in vitro secretion of IL-1beta in a positive manner. Gonadotropin therapy decreased both TNF-alpha and IL-1beta in PBMCs from patients with IHH. The levels of serum IL-2 and IL-4 were also decreased by therapy. In conclusion, in the present study, gonadotropin treatment restored the in vitro production of IL-1beta and TNF-alpha by PBMCs from patients with IHH, suggesting that androgen modulates proinflammatory cytokine production, at least directly through its effects on PBMCs. It seems probable that this effect plays an important role in the immunosuppressive action of androgens.

ABSTRACT: Infections are the emerging causes of mortality and morbidity due to lifelong immunosuppressive therapy in renal transplant patients (1, 4). Here, we report infectious complications of 135 renal allograft recipients who were followed up in the last 20 years in Gülhane Military Medical Academy, Ankara, Turkey. Of them, 83 (61.4%) had a transplant from living related donors, 18 (13.3%) from living non-related HLA matched donors and 34 (25.1%) from cadaveric matched donors. Immunosuppression was achieved in 42 (31.1%) recipients by azathioprine plus corticosteroid (AZA + CS) and in 93 (68.8%) by AZA + CS + cyclosporin A (CsA). Encountered infections were classified according to three different periods of the transplantation procedure [early (first month), intermediate (2-6th months) and late (after the 6th month)]. Bacterial infections were the leading infections in all three periods and the most affected system was the urinary tract. Each recipient had at least one episode of urinary tract infection (UTI) and E. coli was the most common urinary pathogen. On the other hand, HCV was the leading viral pathogen (14.3%). The total mortality rate was 7.4%, and septic shock was the most common cause of death (80%).

ABSTRACT: The aim of this study was to investigate the effects of combined hypocaloric diet and metformin on circulating testosterone and leptin levels in obese men with or without type 2 diabetes.
Twenty obese men with type 2 diabetes (mean body mass index [BMI]: 35.5 +/- 1.1 kg/m(2)) and 20 nondiabetic obese men were enrolled in the study. We measured serum follicle-stimulating hormone, luteinizing hormone (LH), total testosterone (TT), free testosterone (FT), sex-hormone-binding globulin (SHBG), dehydroepiandrosterone sulfate (DHEAS), and plasma leptin levels before and 3 months after metformin treatment. Both groups were placed on a hypocaloric diet and 850 mg of metformin taken orally twice daily for 3 months.
Metformin and hypocaloric diets led to decreases in BMI and waist and hip circumferences in both groups. A significant decrease in TT levels in the diabetic group and FT levels in the control group was found, whereas follicle-stimulating hormone, LH, and DHEAS levels were not changed significantly. A significant increase in SHBG levels was observed in the control group but not in the patient group. Leptin levels also decreased after treatment in both groups. Decreased testosterone levels were not correlated to changes in waist and hip circumference, waist-to-hip ratio, BMI, and levels of fasting blood glucose, leptin, SHBG, or DHEAS in the diabetic group. However, a decrease in FT was correlated to changes in the levels of SHBG (r = -0.71, p = 0.001) and LH (r = 0.80, p = 0.001) but not to other parameters.
We conclude that metformin treatment combined with a hypocaloric diet leads to reduced FT levels in obese nondiabetic men and to reduced TT levels in obese men with type 2 diabetes. Increased SHBG levels may account for the decrease in FT levels in the former group.

ABSTRACT: The mechanisms leading to alterations in plasma melatonin (MT) levels with testosterone replacement in Klinefelter's syndrome (KS) remain elusive. We investigated early morning plasma MT levels, urinary 6-sulfatoxymelatonin (6-SM) levels, and urinary catecholamine levels before and 6 months after testosterone treatment in 31 patients with KS and 20 healthy males to demonstrate whether alterations in plasma MT levels in such patients are due to subtle changes in sympathoadrenal activity and/or alterations in the hepatic indolamine metabolism influenced by testosterone replacement. The plasma MT level was measured by RIA. The sensitivity of the test was 10.7 pmol/L. The 6-SM level was measured by enzyme-linked immunosorbent assay. Urinary catecholamines were determined by high performance liquid chromatography. The pretreatment mean plasma MT level was insignificantly higher in the patient group than in the control group (72.57 +/- 74.82 vs. 42.37 +/- 29.02 pmol/L; z = -1.218; P = 0.223). The pretreatment urinary 6-SM and norepinephrine (NE) levels were significantly lower and, the epinephrine (E) and dopamine levels were insignificantly lower in the patient group than those in the control group [6-SM, 76.54 +/- 31.92 vs. 125.49 +/- 50.16 nmol/L (z = -3.727; P < 0.001); NE, 120.79 +/- 58.33 vs. 178.84 +/- 81.61 nmol/day (z = -2.585; P = 0.01); E, 31.27 +/- 27.42 vs. 34.65 +/- 28.33 nmol/day (z = -0.39; P: = 0.692); dopamine, 1577.02 +/- 863.02 vs. 1812.32 +/- 677.59 nmol/day (z = -1.03, P = 0.308)]. After testosterone replacement, plasma MT levels were significantly decreased (72.57 +/- 74.82 vs. 24.73 +/- 23.61 pmol/L; z = -4.29; P < 0.001), and urinary 6-SM, NE, E, and dopamine levels were significantly increased [6-SM, 25.04 +/- 10.44 vs. 40.05 +/- 17.65 ng/mL (z = -4.78; P < 0.001); NE, 120.78 +/- 58.33 vs. 154.08 +/- 61.35 nmol/day (z = -4.27; P < 0.001); E, 31.27 +/- 27.42 vs. 40.74 +/- 30.04 nmol/day (z = -4.22; P < 0.001); dopamine, 1577.02 +/- 863.02 vs. 2162.67 +/- 823.15 (z = -6.127; P < 0.001)]. There was no relation between plasma MT levels, urinary 6-SM, and catecholamine levels and levels of gonadotropins or gonadal steroids either before or after treatment. We demonstrate that in untreated KS, plasma MT levels tend to be higher than those in normal controls, whereas those of the melatonin metabolite 6-SM and those of NE in urine tend to be lower. After testosterone treatment, however, plasma MT levels fall significantly, whereas urinary levels of 6-SM and NE rise. Our data show that the effect of testosterone is mediated by enhanced metabolism of melatonin, not by any effect on net sympathetic outflow, and that the increase in plasma melatonin in untreated KS patients also results from an alteration in the rate of melatonin metabolism and not from increased net sympathetic activity.

ABSTRACT: Although endemic goiter has been shown to have a high prevalence in Turkey, little is known about the concentration of urinary iodine, plasma selenium (Se), copper (Cu), and zinc (Zn) in these patients. We studied on 140 male patient with endemic goiter (mean age: 22.2 +/- 0.19 yr) and 140 healthy male subjects (mean age: 21.8 +/- 0.28 yr). Daily urinary iodine excretion was determined by the ionometric method. Plasma Se, Zn, and Cu were determined by using atomic absorption spectrometry. Daily urinary iodine excretion was found to be significantly lower in the patient group (38.7 +/- 2.26 microg/d) than that of controls (50.73 +/- 2.56 microg/day, p = 0.001). Plasma Zn concentrations were also found to be significantly lower in the patient group (1.04 +/- 0.03 microg/mL) than that of controls (1.16 +/- 0.02 microg/mL, p = 0.001). No significant difference was determined in Se and Cu concentrations between the patient and control groups. Our study shows that a moderate iodine deficiency exists in both patients with endemic goiter and control subjects, which indicates the important role of iodine deficiency in the etiopathogenesis of endemic goiter in Turkey. Zinc deficiency may also contribute to the pathogenesis of endemic goiter. However, Se and Cu do not seem to have any role in the etiopathogenesis of endemic goiter in Turkey. A community-based iodine fortification program throughout the country may be proposed to take over the problem, which also can prevent the contributing effects of other element deficiencies that occur when iodine deficiency is the prevailing factor.

ABSTRACT: Midstream urine samples taken from 35 patients with secondary haematuria due to nephrolithiasis and 31 patients with haematuria after ESWL were compared using a red cell analyser (RCA) to differentiate the source of haematuria. Urine samples obtained from both groups were examined by RCA for urinary red cell mean corpuscular volume (UMCV) and urinary red cell volume distribution curves (RCVDC). To rule out the influence of blood MCV (BMCV), BMCVs were determined separately and the ratio of UMCV/BMCV (R) was calculated. Although our findings showed no difference between haematurias after ESWL and nephrolithiasis, we cannot exclude a direct effect of shock waves on renal tissue.

ABSTRACT: Gleich syndrome is clinically present with episodes of angioedema, hypereosinophilia, oliguria, and weight gain due to fluid retention which may be sudden and remarkable, sometimes increasing to 10-20% of the baseline weight. The purpose of this study was to evaluate body fluid regulation and hormonal responses during the episode of angioedema and during the recovery phase in a patient with Gleich syndrome. A 24-year-old male was referred to our hospital for further evaluation of recurrent attacks of swellings of face, upper arms, and legs, marked weight gain, and oliguria. On first admission, the patient was in a remission phase, and the initial physical examination showed no abnormalities. Underlying disorders causing edema, such as heart, kidney, and liver diseases, and the recognized causes for hypereosinophilia, such as allergy, parasites, and collagen diseases, were ruled out. After 2 months, since his course was monitored, the patient was hospitalized. During days 10-19, he developed pronounced nonpitting edema of face, upper arms, and legs. Constant leukocytosis and hypereosinophilia, oliguria, and marked weight gain were also noted. A clinical remission was observed without any medication: intensive diuresis, loss of weight, regression of edema, and decreased eosinophil and leukocyte counts within 2 weeks. Physiological mechanisms during edema and resolution are discussed. In conclusion, our patient represents a suitable model for the protection of effective arterial blood volume because of the absence of underlying disorders causing edema. The kidneys play an essential role in the effective arterial blood volume regulation.
