Single-center open-label randomized study of anemia management improvement in ESRD patients with secondary hyperparathyroidism
Whether anemia and mineral bone abnormalities (chronic kidney disease\u2013mineral bone disorder [CKD-MBD]) are associated still remains to be elucidated. Both anemia and CKD-MBD have been associated with adverse cardiovascular outcome and poor quality of life. However, recent evidence suggests that use of large doses of erythropoietin-stimulating agents (ESAs) to correct hemoglobin (Hb) may be detrimental in CKD. The Optimal Anemia Treatment in End Stage Renal Disease (ESRD) (Optimal ESRD Treatment) study will assess whether lowering of parathyroid hormone (PTH) is associated with a reduction in ESA consumption.
The Optimal ESRD Treatment study is a pilot single-center open-label study with blinded end point (a prospective randomized open blinded end-point [PROBE] design) enrolling 50 patients on maintenance dialysis. Eligible patients with intact PTH (iPTH) 300-540 pg/mL and Hb 10-11.5 g/dL will be randomized 1:1 to strict PTH control (150-300 pg/mL) versus standard care (PTH range 300-540 pg/mL). Available drugs for CKD-MBD and anemia treatment will be managed by the attending physician to maintain the desired levels of PTH (according to study arm allocation) and Hb (10-11.5 g/dL). Echocardiographic data for cardiac structure and function as well as arterial stiffness will be assessed at study inception and completion.
The Optimal ESRD Treatment study should shed light on the complicated interplay of anemia and CKD-MBD and on the feasibility of clinical trials in this domain. The study results are expected in the spring of 2017
Sudden Death in End Stage Renal Disease : Comparing Hemodialysis versus Peritoneal Dialysis
Background/Aims: This study aimed to evaluate total and sudden death (SD) in a cohort of dialysis patients, comparing hemodialysis (HD) vs. peritoneal dialysis (PD). Methods: This is a multicenter retrospective cohort study. Results: Deaths were 626 out of 1,823 in HD and 62 of 249 in PD patients. HD patients had a greater number of comorbidities (p < 0.05). PD patients had a lower risk of death than HD patients (p < 0.001); however, the advantage decreased with time (p < 0.001). Mortality predictors were left ventricular ejection fraction (LVEF) \ue2\u89\ua435%, older age, ischemic heart disease, diabetes mellitus, previous stroke, and atrial fibrillation (p < 0.03). SDs were 84:71 in HD and 13 in PD population (12.1 and 22.8% of all causes of death, respectively). A non-significant risk of SD among PD compared to HD patients was detected. SD predictors were older age, ischemic heart disease, and LVEF \ue2\u89\ua435% (p < 0.05). Conclusions: HD patients showed a greater presence of comorbidities and reduced survival compared to PD patients; however, the incidence of SD does not differ in the 2 populations.

Association analysis of the functional Ala111Glu polymorphism of the glyoxalase I gene in panic disorder
The zinc metalloenzyme glyoxalase I (GLO1) is thought to play a role in anxiety disorders because a reduced brain expression of GLO1 has been associated with increased anxiety-behaviours in mice. Recently, a functional Ala111Glu polymorphism in GLO1 has been shown to result in a reduced enzyme activity. The present study tested the hypothesis that this common genetic variant could confer susceptibility to panic disorder using an Italian population sample of 162 panic disorder patients and 288 matched controls. Statistical analysis failed to show association with the overall diagnosis of the disease. However, a weak but significant association was demonstrated between this polymorphism and panic disorder without agoraphobia. While our data suggest that this polymorphism is unlikely to have a major function in the pathogenesis of panic disorder, it could play a role in the subgroup of patients without agoraphobic avoidance

The T393C polymorphism of the GNAS1 gene is associated with deficit schizophrenia in an Italian population sample
Programmed cell death and alterations in intracellular G-protein signaling may be involved in the pathophysiology of schizophrenia. The Galphas subunit of heterotrimeric G-proteins, encoded by the gene GNAS1, may play a role in both of these processes. Additionally, transgenic mice expressing a constitutively active form of Galphas provide a reliable model of certain endophenotypes of schizophrenia. To investigate whether the functional single nucleotide polymorphism T393C in GNAS1 gene could affect risk of schizophrenia, we examined its distribution in Italian subjects with (n=383) and without (n=400) schizophrenia. We also evaluated whether a specific association could exist between the deficit (n=108) and nondeficit (n=275) forms of the disorder. The alleles and genotypes frequency in the entire cohort of schizophrenic patients did not differ from that of controls. However, the frequency of the homozygous 393TT genotype was significantly higher in deficit schizophrenic patients (37.1%) compared to both nondeficit schizophrenic (22.5%, p=0.011) and controls (22.8%, p=0.015). This association with deficit schizophrenia persisted even after allowance for potential confounders [adjusted odds ratio (OR) for deficit schizophrenia: 2.06 (95% confidence interval (CI): 1.21-3.47), p=0.007]. Altogether, our data suggest that the GNAS1 T393C status could influence susceptibility for deficit schizophrenia in Italian subjects
