Increased serum prolactin in borderline personality disorder

Although there is an important interaction between serotonergic system, prolactin and suicidal behavior, and impulsivity, no investigation examined the prolactin values in borderline personality disorder in which suicidal behavior and impulsivity are core symptom dimensions. In this context, in the present investigation, we planned to measure serum prolactin levels in the patients with borderline personality disorder. The study comprised 15 patients with borderline personality disorder and 15 healthy controls. Prolactin values were measured in both patients and control subjects. The patients had abnormally higher mean value of prolactin compared to those of healthy controls (48.66 ± 36.48 mg/dl for patients vs. 15.20 ± 7.81 mg/dl for healthy controls). There was no correlation between prolactin values and any demographic variables for both the patients and control subjects. In conclusion, our present results suggest that prolactin values increased in the patients with borderline personality disorder and are required to be replicated by more comprehensive and detailed further studies to decipher the exact roles of prolactin increase.

Associations of serum Magnesium levels with diabetes mellitus and diabetic complications

BACKGROUND

Magnesium (Mg) deficiency is a common problem in diabetic patients. Deficiency of Mg may increase the incidence of diabetes mellitus (DM) and occurrence of diabetic complications. In this study, our aim was to evaluate an association between serum Mg level,  glycemic regulation, and diabetic complications.

MATERIAL-METHODS

In this retrospective study 673 diabetic patients were evaluated. According to Mg levels, the patients were divided into two groups; as normomagnesemic patients and hypomagnesemic patients.

RESULTS

Among the patients, 57.8% were men and 42.2% were women. Mean age was 55.6 years and the mean duration of diabetes was 81 ± 86.9 months. The mean glycosylated hemoglobin (HbA1c) was 9.0 ±2.4 % (4.5-18); mean magnesium level was 1.97 ± 0.25 (1.13 to 3.0) mg / dl.  There were 55 patients (8.2%) with diabetic retinopathy and 95 patients (14.1%) with diabetic neuropathy. Five hundred patients (74.3%)  had normoalbuminuria; 133 patients (19. 8%) had microalbuminuria (MA) and 40 patients (5.9%) had overt proteinuria. One hundred and seventy one patients (25.4%) had HbA1c levels equal or below 7%; and 502 patients (74.6%) had HbA1c levels above 7%. There was no statistical difference in age or duration of diabetes between the groups formed according to Mg levels. Although there were no differences between the groups for retinopathy and neuropathy, MA was more common in hypomagnesemic patients (p =0.004). HbA1c levels did not differ between the groups (p =0.243). However there was a weak negative correlation between serum Mg and HbA1c levels (r =-0.110, p =0.004) and also between serum Mg and urine protein level  (r =-0.127, p =0.018).

CONCLUSION

Mg depletion is a common problem in patients with DM. It affects both glycemic regulation and the occurence of complications. Also, poor glycemic regulation affects serum Mg levels. Hippokratia 2015; 19 (2):153-157.

Frequency of anemia in chronic psychiatry patients

PURPOSE

Anemia could cause psychiatric symptoms such as cognitive function disorders and depression or could deteriorate an existing psychiatric condition when it is untreated. The objective of this study is to scrutinize the frequency of anemia in chronic psychiatric patients and the clinical and sociodemographic factors that could affect this frequency.

METHODS

All inpatients in our clinic who satisfied the study criteria and received treatment between April 2014 and April 2015 were included in this cross-sectional study. Sociodemographic data for 378 patients included in the study and hemoglobin (Hb) and hematocrit values observed during their admission to the hospital were recorded in the forms. Male patients with an Hb level of <13 g/dL and nonpregnant female patients with an Hb level of <12 g/dL were considered as anemic.

FINDINGS

Axis 1 diagnoses demonstrated that 172 patients had depressive disorder, 51 patients had bipolar disorder, 54 patients had psychotic disorder, 33 patients had conversion disorder, 19 patients had obsessive-compulsive disorder, 25 patients had generalized anxiety disorder, and 24 patients had other psychiatric conditions. It was also determined that 25.4% of the patients suffered from anemia. Thirty-five percent of females and 10% of males were considered as anemic. The frequency of anemia was the highest among psychotic disorder patients (35%), followed by generalized anxiety disorder patients (32%), and obsessive-compulsive disorder patients (26%). Anemia was diagnosed in 22% of depressive disorder patients, 25% of bipolar disorder patients, and 24% of conversion disorder patients.

RESULTS

The prevalence of anemia among chronic psychiatry patients is more frequent than the general population. Thus, the study concluded that it would be beneficial to consider the physical symptoms and to conduct the required examinations to determine anemia among this patient group.

Is there any association between mild hypertension and hot flash experience among women?

OBJECTIVE

To determine the association between ambulatory blood pressure (ABP), heart rate, and hot flash (HF) experience among women.

MATERIALS AND METHODS

The authors recruited 110 women aged 22 to 65 years with mild essential hypertension or normotension confirmed by 24-hour ABP monitoring. None of the women had organ damage, inflammatory diseases, on estrogen replacement therapy or any other risk factors. Participants wore an ABP monitor that both records heart rate during 24 hours and noted their awake and sleep times. HF were assessed using an everyday complaint questionnaire that included symptoms associated with menopause. Each participant was asked whether or not she had experienced each symptom during the two weeks before the interview.

RESULTS

Fifty-five of the participants (45%) reported having had HF during the two weeks before they completed the questionnaire. The results show that the prevalence of essential hypertension (EH) in the group of women who had HF was significantly higher than the group of women that did not have HF (p = 0.035). The authors also found that hypertensive women had HF more often than normotensive women (p = 0.035), but other parameters including mean awake and sleep systolic BP values, mean awake and sleep diastolic BP values, heart rates, and nocturnal dipping of BP did not differ statistically among the group of women who had HF and the group of women who did not have HF (p > 0.05).

CONCLUSIONS

These data suggest that the prevalence of EH in the group of women who have HF is significantly higher than the group of women that does not have HF.

The role of bilirubin and its protective function against coronary heart disease

BACKGROUND

Atherosclerotic cardiovascular disease is the leading cause of morbidity and mortality both in industrialized and developing countries. Atherosclerosis is a chronic inflammatory disease of the arterial wall, which also involves deposition and peroxidation of lipids. Bilirubin, an important endogenous antioxidant, may limit lipid peroxidation and retard the progression of atherosclerosis. Previous studies have reported an inverse relationship between serum bilirubin levels and the risk of coronary artery disease (CAD). Taking into account that atherosclerosis is a complex process that is initiated and accelerated by diverse risk factors, we aimed to test the antiatherosclerotic effects of bilirubin in a population with multiple risk factors for CAD.

METHODS

The study included 221 patients who underwent coronary angiography owing to symptoms suggestive of ischemia and/or positive noninvasive stress test results. Of the patients, 76 had normal coronary angiograms and served as the control group. The remaining 145 patients with documented CAD and two or more cardiovascular risk factors constituted the study group. The study group (n=145) was further classified according to the Gensini score as follows: group 1 if Gensini score was 1-19 (minimal CAD, n=82), and group 2 if Gensini score was 20 or higher (significant CAD, n=63). Biochemical assessments including total and direct serum bilirubin levels were carried out using standard methods in automated systems.

RESULTS

All of the cardiovascular risk factors were found significantly more frequently in the study group (groups 1 and 2) than in the control group. Total and direct serum bilirubin levels did not differ significantly between the control group, group 1, and group 2. There was a moderate and significant positive correlation between direct bilirubin levels and the Gensini score (r = 0.158, p = 0.019). There was no significant correlation between total bilirubin levels and the Gensini score.

CONCLUSION

In conclusion, our findings suggest that in the presence of multiple risk factors, similar concentrations of serum bilirubin may not confer the same level of protection against CAD as in an individual with a more favorable risk profile. The relationship between direct bilirubin levels and the Gensini score is unlikely to be causative, given the established antiatherosclerotic effects of bilirubin.

Addition of vardenafil into storage solution protects the endothelium in a hypoxia-reoxygenation model

OBJECTIVE

Based upon the well known protective effect of intracellular cyclic guanosine monophosphate (cGMP) accumulation, we tested the hypothesis that storage solution enriched with optimal concentration of the phosphodiestherase-5 inhibitor vardenafil could provide better protection of vascular grafts against reperfusion injury after long-term cold ischaemic storage.

METHODS

Isolated thoracic aorta obtained from rats underwent 24-h cold ischaemic preservation in physiological saline or vardenafil (10(-11) M)-supplemented saline solution. Reperfusion injury was simulated by hypochlorite (200 μM) exposure for 30 minutes. Endothelium-dependent vasorelaxation was assessed, and histopathological and molecular-biological examination of the aortic tissue were performed.

RESULTS

Compared with the control group, the saline group showed significantly attenuated endothelium-dependent maximal relaxation (Rmax) to acetylcholine after hypoxia-reoxygenation, which was significantly improved by vardenafil supplementation (Rmax control: 98 ± 1%; saline: 48 ± 6%; vardenafil: 75 ± 4%; p < .05). Vardenafil treatment significantly reduced DNA strand breaks (control: 10.6 ± 6.2%; saline: 72.5 ± 4.0%; vardenafil: 14.2 ± 5.2%; p < .05) and increased cGMP score in the aortic wall (control: 8.2 ± 0.6; saline: 4.5 ± 0.3; vardenafil: 6.7 ± 0.6; p < .05).

CONCLUSIONS

Our results support the view that impairment of intracellular cGMP signalling plays a role in the pathogenesis of the endothelial dysfunction induced by cold storage warm reperfusion, which can be effectively reversed by pharmacological phosphodiesterase-5 inhibition.
