Leptin may have roles in the development of prostate cancer through testosterone and factors related to obesity. It influences cellular differentiation and the progression of prostate cancer.
In this study we investigated cytokine levels in patients with familial Mediterranean fever (FMF). Twenty patients and 20 healthy controls were included. Ten patients had acute attacks of FMF, whereas the other 10 were in the silent period. Patients with the acute exacerbation of FMF had higher soluble interleukin-2 receptor (sIL-2r), interleukin-6 (IL-6), tumour necrosis factor-alpha, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and fibrinogen levels than those in the silent period ( P<0.001) and controls ( P<0.001). In patients with acute attacks of FMF, interleukin-10 (IL-10) levels were not significantly different from those in the other patients or the controls ( P>0.05). In FMF patients IL-6, TNF-alpha, sIL-2r, ESR, CRP and fibrinogen levels increased with the acute-phase reaction, especially in the attack period. On the other hand, anti-inflammatory cytokine IL-10 levels did not increase as much as did the inflammatory cytokines. The balance between the cytokines may help us to understand the pathophysiology of FMF and to develop therapies. We conclude that the levels of the acute-phase reactants and the cytokines could be useful for diagnosis of acute exacerbations, follow-up and treatment. However, the cost of cytokine measurement analyses seems disadvantageous at present.
The present study was conducted to evaluate the serum copper, zinc, magnesium, and selenium levels in patients with subclinical hypothyroidism in the iodine-rich region of Ankara, Turkey. The effects of hormone replacement therapy on these elements were also studied in these patients. Basal levels of selenium and iron in patients were significantly lower than control group (67.7 +/- 10.4 vs. 83.7 +/- 17.3 microg/dl, p = 0.02; 55.7 +/- 38 vs 275.7 +/- 24, P = 0.03 microg/dl). Serum magnesium levels were significantly higher in patient group (2.16 +/- 0.31 vs 1.95 +/- 0.13 mg/dl, P < 0.0001). There was a correlation between selenium levels with hsCRP (r = -0.408, p = 0.007). HsCRP levels in patients with selenium levels <80 microg/l (n = 31) was significantly higher than hsCRP levels in patients with selenium levels >80 microg/l (n = 12; 1.99 +/- 1.0; 1.02 +/- 0.9, p = 0.014). None of these biochemical risk factors and trace elements have changed after euthyroidism in patients with SH when compared to pretreatment levels. Selenium deficiency may contribute to cardiovascular disease risk in these patients.
Statins have multiple actions, independent of their classical effects on lipoproteins. The data about the effects of statins on insulin resistance is controversial. This study was designed to search the statin effects on nondiabetic dyslipidemic patients. Thirty-five (17 male, 18 female) consecutive dyslipidemic patients 54.25 +/- 8.81 yr were enrolled in the study. After a standard follow-up period of lifestyle modification, the patients were given fluvastatin 40 mg/d for 8 wk. Serum analyses were done both before and after treatment. Insulin resistance was assessed by homeostasis assessment model (HOMA). Fasting plasma triglyceride, total and LDL cholesterol, fasting insulin, and HOMA index were significantly reduced and HDL cholesterol was improved after fluvastatin treatment. HOMA-IR was not correlated with triglycerides, LDL, HDL, or total cholesterol levels. The same situation was present for both fasting plasma insulin and fasting plasma glucose levels. Also age was not associated with HOMA-IR and fasting plasma insulin levels. As a conclusion, the present study indicates that fluvastatin treatment improves insulin resistance in dyslipidemic patients who do not have diabetes or impaired fasting glucose. Also, the effect of fluvastatin on insulin resistance is not associated with the lowering of triglycerides. The latter finding indicates that the effect of statins on insulin sensitivity may not be related with the lowering of triglycerides in dyslipidemic patients.
The cumulative dose of cisplatin is a strong risk factor for the development of nephrotoxicity in patients who receive high doses of ICE followed by PBSCT. Nephrotoxicity may occur with much lower doses than the currently recommended maximum doses.
Pentraxin 3 (PTX3) is a new candidate immunoinflammatory marker that has been reported to be associated with cardiometabolic risk factors. We aimed to investigate the effects of valsartan and amlodipine on the PTX3 and C-reactive protein (CRP) levels in patients with essential hypertension. Patients with a newly diagnosed essential hypertension were admitted to our internal medicine outpatient clinic. Patients were randomized to one of the following intervention protocols: calcium channel blocker (amlodipine, 5-10 mg/day) as group A (n = 22; mean age ± standard deviation [SD]: 52 ± 11 year) and angiotensine II receptor blocker (valsartan, 80-320 mg/day) as group B (n = 28; mean age ± SD: 50 ± 14 year). Endothelial dysfunction and systemic inflammation were evaluated with PTX3 and CRP. There was a significant decrease in the level of PTX3 after treatment in two groups (P < .05). Although there was a significant decrease in the level of CRP after treatment in amlodipine group, there was no significant decrease in the levels of PTX3 and CRP after treatment in two groups. There were no significant differences in the systolic and diastolic blood pressure reduction between the two treatment groups. In the treatment of hypertension, prior knowledge of the level of plasma PTX3 could be important in antihypertensive drug choice. C-reactive protein and PTX3 are the markers that have role in vascular inflammation and are found associated with the prognosis of cardiovascular outcomes in many trials. In our study, PTX and CRP levels were decreased when compared to baseline levels.
Introduction and Aim:Many etiological reasons are blamed for enuresis nocturna (EN). The aim of this study was to research prevalence and severity of EN among elementary school-age children and sociodemographic risk factors related to it.Materials and Methods:The study was performed in three elementary schools in Ankara, Turkey between January and May 2011. It was planned to have 2500 students of 6–14 ages in the study. The questionnaire, which consisted of questions, aiming to evaluate the EN condition of participants and their characteristics, were distributed to the parents. It was observed that 2314 participants’ questionnaires (92.56%) were in accordance with evaluation criteria.Statistical Analysis:The relation between EN and the sociodemographic factors was evaluated through Chi-square test and logistic regression analysis.Results:The mean age of 2314 participants was 9.21 ± 2.08. 48.5% (n = 1123) of the students were male and 51.5% (n = 1191) were female. While the general EN prevalence was 9.9% (n = 230); 10.7% (n = 120) for males, as 9.2% (n = 110) for females. Statistical significant difference was determined between the two groups, with EN and without EN, regarding age groups (P < 0.001), education level of parents (P < 0.001, P < 0.001), and the number of sibling (P = 0.002), income level (P < 0.001), and positive family history (P < 0.001). However, logistic regression analysis revealed that there was a significant difference only between EN and age groups (odds ratio [OR] =4.42, P < 0.001), education level of mother (OR = 2.13, P = 0.017) and family history (OR = 0.12, P < 0.001).Conclusions:As a consequence, such factors as age groups, education level of parents, positive family history could be accepted as a risk of concerning EN. It is important to perform a detailed evaluation on population, carrying risk of having EN.
