The advent of multicellular organisms was accompanied by the development of short- and long-range chemical signalling systems, including those provided by the nervous and endocrine systems. In turn, the cells of these two systems have developed mechanisms for interacting with both adjacent and distant cells. With evolution, such mechanisms have diversified to become integrated in a complex regulatory network, whereby individual endocrine and neuro-endocrine cells sense the state of activity of their neighbors and, accordingly, regulate their own level of functioning. A consistent feature of this network is the expression of connexin-made channels between the (neuro)hormone-producing cells of all endocrine glands and secretory regions of the central nervous system so far investigated in vertebrates. This review summarizes the distribution of connexins in the mammalian (neuro)endocrine systems, and what we know about the participation of these proteins on hormone secretion, the life of the producing cells, and the action of (neuro)hormones on specific targets. The data gathered since the last reviews on the topic are summarized, with particular emphasis on the roles of Cx36 in the function of the insulin-producing beta cells of the endocrine pancreas, and of Cx40 in that of the renin-producing juxta-glomerular epithelioid cells of the kidney cortex.

Studies indicate that inflammatory mechanisms may play an important role in the pathogenesis of Alzheimers disease (AD). C-reactive protein (CRP), marker and mediator of inflammation, has been detected in lesions typical for the affected areas of AD brain. There have been conflicting reports on serum CRP concentration in AD. Scarce data exist on association of CRP and measures of adiposity in AD patients. Thus, we investigated serum CRP concentration in fifteen overweight institutionalized patients with probable AD and fifteen age-matched control subjects. Body mass index (BMI) and waist/hip ratio (WHR) were calculated for each subject included in the study. Age, systolic and diastolic blood pressure, BMI and WHR did not differ significantly between the two groups. Serum CRP concentration was significantly higher in patients with AD compared to controls (p<0.0001). Although not significant, positive correlations between serum levels of CRP and BMI and WHR were found. Obtained results support the notion that low-grade inflammation is present in patients with AD. Absence of significant association between CRP and measures of total and central adiposity in overweight AD patients needs further investigation and explanation.

AIM γ-glutamyl transferase (GGT) is an independent prognostic marker for cardiac death and reinfarction in patients with coronary artery disease, but its clinical significance during early postmyocardial infarction period is unclear. PATIENTS & METHODS This short-term prospective study included 40 patients with acute myocardial infarction (AMI) in whom we determined GGT activity, lipids, uric acid, homocysteine (Hcy), high sensitivity C-reactive protein (hsCRP) and left ventricular (LV) function on admission and on day 5 following AMI. RESULTS In AMI patients on admission, logGGT was associated with logHcy (r = 0.36), uric acid (r = 0.48) and CK-MB activity (r = -0.41). Uric acid remained an independent determinant of serum GGT activity on admission. Significant increase in GGT activity (77.7%) was observed following AMI. On day 5 serum logGGT was significantly associated with LV relative wall thickness (r = -0.37), LV end-diastolic diameter (r = 0.41) and LV fractional shortening (r = -0.36). In addition, a significant positive correlation was found between serum logGGT and loghsCRP (r = 0.41) and logHcy values (r = 0.395), but only LV end-diastolic diameter remained independently associated with serum GGT activity on day 5 following AMI. CONCLUSION GGT is associated with oxidative/inflammatory markers and LV diastolic diameter suggesting its potential role in predicting LV dilatation and dysfunction during the early postmyocardial infarction period.

Objectives: Aim of the present study was to investigate serum concentration of leptin and its association with values of body mass index (BMI), C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR) in hemodialysis (HD) patients. Methods: This cross-sectional study included 60 HD patients (34 male, 26 female) and 30 age- and sex-matched (4 males, 26 females) apparently healthy subjects. Serum leptin concentration was determined by an enzyme-linked immunosorbent assay (ELISA). Serum CRP concentration was measured by means of particle-enhanced immunonephelometry. ESR value was determined by Western Green method. BMI was calculated as weight (kg) divided by height squared (m2). Results: Results have shown that median serum leptin concentration (30.65 ng/mL; 12.48-86.40 ng/mL) was statistically significantly higher in HD patients compared to median serum leptin concentration (15.75 ng/mL; 9.15-30.65 ng/mL) in the control group of healthy subjects (p<0.05). Likewise, median serum CRP concentration (5.5 mg/L; 1.93-8.9 mg/L) and median ESR value (57.5 mm/h; 40.5-77.0 mm/h) were significantly higher in HD patients compared to median serum CRP concentration (0.8 mg/L; 0.38-1.43 mg/L) (p<0.001) and median ESR value (10.0 mm/h; 6.5-14.0 mm/h) (p<0.001) determined in the control group. Statistically significant positive correlation was found between BMI values and serum leptin concentration in HD patients (rho=0.434; p<0.001). Positive, although not significant, correlation was observed between serum CRP and leptin levels in HD patients (rho=0.171; p>0.05). Negative correlation between ESR values and serum leptin concentrations in HD patients was determined but it was not statistically significant (rho= -0.029; p>0.05). Conclusions: Increased serum concentration of leptin as pro-inflammatory cytokine as well as elevated serum values of CRP and ESR indicate presence of systemic micro inflammation in HD patients. Results of the present study point to possible use of serum leptin concentration as an indicator of nutritional status in HD patients based on observed significant positive correlation between serum leptin concentrations and BMI values. However, absence of significant association between serum leptin and CRP levels as well as between serum leptin concentrations and ESR values in HD patients requires further investigation and clarification.

This study investigated whether serum C-reactive protein (CRP) concentration is increased in patients with type 1 diabetes mellitus with a normal body mass index (BMI) and whether BMI, glycated haemoglobin (HbA1c) and CRP are correlated in patients with type 1 diabetes. High-sensitivity CRP was determined by immunonephelometry and HbA1c by an immunoturbidimetric method in 30 patients with type 1 diabetes and 30 healthy individuals matched for age, sex and BMI. Median serum CRP concentration in patients with type 1 diabetes (1.34 mg/L) was significantly higher than healthy individuals (0.2 mg/L; p<0.0001). Positive correlation between CRP and BMI was observed (rho=0.598; p<0.0001), but no significant correlation was observed between CRP and HbA1c (rho=0.285; p=NS) in patients with type 1 diabetes. Increased CRP levels in type 1 diabetes patients do not appear to be associated with glycaemic control, and may reflect low-grade inflammation associated with atherosclerosis, as well as activation of innate immune activity.

Abstract Background: The ε2, ε3 and ε4 alleles of APOE gene have been associated with several diseases in different populations. Data on the frequency of alleles are used in both a clinical and evolutionary context. Although the data on frequency of these alleles are numerous, there are no reports for the population of Bosnia and Herzegovina. Aim: To estimate the frequency of APOE alleles in a healthy Bosnian population and compare it to data for other European populations. Subjects and Methods: Overall, 170 unrelated Bosnian subjects (108 female and 62 male), aged 53.0 (±5.0) years were included in this study. Genotypes were determined by real-time PCR. Results: In our group the prevalence of heterozygotes E2/E3, E2/E4 and E3/E4 was 20.6%, 3.5% and 12.9%, respectively, while the prevalence of homozygotes E2/E2, E3/E3, E4/E4 was 0.6%, 61.2% and 1.2%, respectively, with a mean frequency of ε2, ε3 and ε4 alleles of 12.6%, 78.0% and 9.4%, respectively. Conclusions: In studied European populations we observed a linear, gradually increasing trend in the frequency of ε4 allele from South to North (Pearson’s test 0,7656, p value <0.00001), and the Bosnian population fits into this pattern perfectly.
