Cím:Severe Symptomatic Hypocalcemia after Denosumab Administration in an End-Stage Renal Disease Patient on Peritoneal Dialysis with Controlled Secondary Hyperparathyroidism / Mohit Agarwal, Éva Csongrádi, Christian A. Koch, Luis A. Juncos, Vonda Echols, Mihály Tapolyai, Tibor Fülöp
Dátum:2013
Megjegyzések:We report the 1st case of severe, symptomatic hypocalcemia after denosumab (RANKLinhibitor) treatment in a peritoneal dialysis patient with secondary hyperparathyroidismand osteoporosis. A 58-year-old Caucasian female has been receiving chronicambulatory peritoneal dialysis for four years secondary to polycystic kidney disease.Laboratory studies revealed: albumin-corrected calcium 9.0 mg/dL, phosphorus 5 mg/dL,alkaline phosphatase (ALP) 58 U/L [normal, 40-105], albumin 3.4 gm/dL [normal, 3.6-5.4]and intact parathyroid hormone (PTH) 315 pg/mL [normal, 40-72]. Marked osteoporosiswas noted on the DXA scan, preventing her from renal transplantation considerations.She had failed conventional medical treatment, including per os calcium, monthlyergocalciferol (50,000 units/month), activated vitamin-D analog (doxercalciferol) andrenal-failure adjusted alendronate (70 mg twice a month). She was started onsubcutaneous denosumab 60 mg every 6 months. After her first dose, she developed aprogressive drop of calcium, phosphorus, bicarbonate and magnesium, in spite ofmassive escalation of doxercalciferol and calcium supplementation. Hypocalcemianadired at 6.3 mg/dL with symptomatic tetany, requiring a brief hospitalizationapproximately 7 weeks after denosumab treatment. Her elevated PTH rose furthertransiently (647 pg/mL), along with ALP (123 U/L). Bone-mineral parameters normalizedapproximately 3 months after denosumab administration. The observed phenomenonresembled the phenotype of "hungry bone syndrome" observed after surgicalparathyroidectomy.Conclusion: Treatment decisions based on bone densitometry results alone are nottransposable between patients with or without end-stage renal disease. Denosumab maylead to critical hypocalcemia in dialysis patients and further aggravate existing secondaryhyperparathyroidism.

Megjegyzések:Background: Intravenous immune globulin (IVIG) for the treatment of dermatomyositis has not been extensively evaluated. Methods: We conducted a randomized, placebo-controlled trial involving patients with active dermatomyositis. The patients were assigned in a 1:1 ratio to receive IVIG at a dose of 2.0 g per kilogram of body weight or placebo every 4 weeks for 16 weeks. The patients who received placebo and those without confirmed clinical deterioration while receiving IVIG could enter an open-label extension phase for another 24 weeks. The primary end point was a response, defined as a Total Improvement Score (TIS) of at least 20 (indicating at least minimal improvement) at week 16 and no confirmed deterioration up to week 16. The TIS is a weighted composite score reflecting the change in a core set of six measures of myositis activity over time; scores range from 0 to 100, with higher scores indicating greater improvement. Key secondary end points included at least moderate improvement (TIS ?40) and major improvement (TIS ?60), and change in score on the Cutaneous Dermatomyositis Disease Area and Severity Index. Results: A total of 95 patients underwent randomization: 47 patients were assigned to the IVIG group, and 48 to the placebo group. At 16 weeks, 79% of the patients in the IVIG group (37 of 47) and 44% of those in the placebo group (21 of 48) had a TIS of at least 20 (difference, 35 percentage points; 95% confidence interval, 17 to 53; P<0.001). The results with respect to the secondary end points, including at least moderate improvement and major improvement, were generally in the same direction as the results of the primary end-point analysis, except for the change in creatine kinase level (an individual core measure of the TIS), which did not differ meaningfully between the two groups. Over 40 weeks, 282 treatment-related adverse events occurred in the IVIG group, including headache (in 42% of patients), pyrexia (in 19%), and nausea (in 16%). A total of 9 serious adverse events that were considered to be related to IVIG occurred, including 6 thromboembolic events. Conclusions: In this 16-week trial involving adults with dermatomyositis, the percentage of patients with a response of at least minimal improvement based on a composite score of disease activity was significantly greater among those who received IVIG than among those who received placebo. IVIG was associated with adverse events, including thromboembolism. (Funded by Octapharma Pharmazeutika; ProDERM ClinicalTrials.gov number, NCT02728752.).

Megjegyzések:Intracellular free heme predisposes to oxidant-mediated tissue damage. We hypothesized that free heme causes alterations in myocardial contractility via disturbed structure and/or regulation of the contractile proteins. Isometric force production and its Ca2þ-sensitivity (pCa50) were monitored in permeabilized human ventricular cardiomyocytes. Heme exposure altered cardiomyocyte morphology and evoked robust decreases in Ca2þ-activated maximal active force (Fo) while increasing Ca2þ-independent passive force (Fpassive). Heme treatments, either alone or in combination with H2O2, did not affect pCa50. The increase in Fpassive started at 3 mM heme exposure and could be partially reversed by the antioxidant dithiothreitol. Protein sulfhydryl (SH) groups of thick myofilament content decreased and sulfenic acid formation increased after treatment with heme. Partial restoration in the SH group content was observed in a protein running at 140 kDa after treatment with dithiothreitol, but not in other proteins, such as filamin C, myosin heavy chain, cardiac myosin binding protein C, and α-actinin. Importantly, binding of heme to hemopexin or alpha-1-microglobulin prevented its effects on cardiomyocyte contractility, suggesting an allosteric effect. In line with this, free heme directly bound to myosin light chain 1 in human cardiomyocytes. Our observations suggest that free heme modifies cardiac contractile proteins via posttranslational protein modifications and via binding to myosin light chain 1, leading to severe contractile dysfunction. This may contribute to systolic and diastolic cardiac dysfunctions in hemolytic diseases, heart failure, and myocardial ischemia-reperfusion injury.

Cím:Inhibition of TRPC6 by protein kinase C isoforms in cultured human podocytes / Lídia Ambrus, Attila Oláh, Tamás Oláh, György Balla, Moin A. Saleem, Petronella Orosz, Judit Zsuga, Klára Bíró, László Csernoch, Tamás Bíró, Tamás Szabó

Megjegyzések:Transient receptor potential canonical-6 (TRPC6) ion channels, expressed at high levels in podocytes of the filtration barrier, are recently implicated in the pathogenesis of various forms of proteinuric kidney diseases. Indeed, inherited or acquired up-regulation of TRPC6 activities are suggested to play a role in podocytopathies. Yet, we possess limited information about the regulation of TRPC6 in human podocytes. Therefore, in this study, we aimed at defining how the protein kinase C (PKC) system, one of the key intracellular signalling pathways, regulates TRPC6 function and expression. On human differentiated podocytes, we identified the molecular expressions of both TRPC6 and several PKC isoforms. We also showed that TRPC6 channels are functional since the TRPC6 activator 1-oleoyl-2-acetyl-sn-glycerol (OAG) induced Ca2+-influx to the cells. By assessing the regulatory roles of the PKCs, we found that inhibitors of the endogenous activities of classical and novel PKC isoforms markedly augmented TRPC6 activities. In contrast, activation of the PKC system by phorbol 12-myristate 13-acetate (PMA) exerted inhibitory actions on TRPC6 and suppressed its expression. Importantly, PMA treatment markedly down-regulated the expression levels of PKCa, PKCb, and PKCg reflecting their activation. Taken together, these results indicate that the PKC system exhibits a 'tonic' inhibition on TRPC6 activity in human podocytes suggesting that pathological conditions altering the expression and/or activation patterns of podocyte-expressed PKCs may influence TRPC6 activity and hence podocyte functions. Therefore, it is proposed that targeted manipulation of certain PKC isoforms might be beneficial in certain proteinuric kidney diseases with altered TRPC6 functions.

Megjegyzések:In this paper, results of a diabetic retinopathy screening experiment are presented which is based solely on the findings of a microaneurysm detector. For this purpose, an ensemble-based algorithm developed by our research group was used; this provided promising results in our earlier experiments. At its best, the 1200 image of the Messidor database is classified by this detector with a sensitivity of 96%, a specificity of 51% and achieved an AUC of 0.87. As anticipated, larger microaneurysm counts are recognized with higher level of certainty. Therefore, this approach might be expected to have good performance in relation to the severity of the disease.

Cím:Lamotrigine effectively blocks synaptic transmission between nociceptive primary afferents and secondary sensory neurons in the rat superficial spinal dorsal horn / Zsófia Antal, Péter Szűcs, Miklós Antal
Dátum:2011
Megjegyzések:It has been demonstrated that in the superficial spinal dorsal horn, Lamotrigine, which is known to block voltage-sensitive Na+ and Ntype Ca2+ channels, depresses neural activities evoked by sustained activation of nociceptive primary afferent fibres. In the present experiments, we study how Lamotrigine exerts its inhibitory effect on spinal nociceptive information-processing mechanisms. We show that Lamotrigine in an in vitro slice preparation effectively blocks synaptic transmission between primary afferents and secondary sensory neurons. Together with the robust increase in the failure rate and reduction in the amplitude of excitatory post-synaptic potentials (EPSPs) evoked by stimulation of nociceptive primary afferents, Lamotrigine causes a marked decrease in the number and amplitude of spontaneous EPSPs and a gradual shift of the resting membrane potential towards hyperpolarization. In addition, Lamotrigine treatment also changes the intrinsic firing pattern of superficial dorsal horn neurons. The results suggest that the effect of Lamotrigine on spinal nociceptive information-processing mechanisms is multiple: it depresses synaptic inputs from nociceptive primary afferents to secondary spinal sensory neurons and also weakens the intrinsic activities of nociceptive spinal neural circuits in the superficial spinal dorsal horn.

Papp21Department of Laboratory Medicine, 2Department of Internal Medicine, Division of Gastroenterology, 3Institute of Surgery, Faculty ofMedicine, University of Debrecen, Debrecen, HungaryBacterial infections are a significant cause of morbidity and mortality in cirrhosis. Lectin pathway molecules of the complement system aresynthesized in the liver and have a pivotal role in the innate host defense against infectious organisms. Mannose-binding lectin (MBL) andficolins (FCNs) act as soluble pattern recognition molecules, while mannan-binding lectin serine proteases (MASPs) are effector molecules inelimination of the pathogens. Low levels of the functional proteins increase the risk of various infectious diseases but their significance hasscarcely been investigated in cirrhosis related bacterial infections.Sera of 266 patients with cirrhosis and 160 healthy subjects were assayed for the concentrations of FCN-2, FCN-3 and MASP-2 by ELISAs.In cirrhosis, a 5-year follow-up observational study was conducted to assess a possible association between lectin levels and development ofclinically significant bacterial infections (CSI) and mortality.The FCN-2, FCN-3 and MASP-2 levels were significantly lower in cirrhosis compared to healthy controls (505 vs. 769 ng/ml, 7,301 vs.10,797 ng/ml and 212 vs. 412 ng/ml, respectively, p < 0.001 for all) and decreased according to disease severity as rated by Child-Pughstage. In Kaplan-Meier analysis time to development of CSI was associated with low level of FCN-3 ( < 4,857 ng/ml, p = 0.028) but notFCN-2 ( < 427 ng/ml, p = 0.068) or MASP-2 deficiency (p = 0.368). Combined FCN deficiency even more than individual molecules wereable to predict the development of these episodes. Patients with low level of both FCNs had a cumulative risk of an infection of 52%as compared to 31% with normal level of FCNs (p = 0.021). In multivariate Cox-regression analysis, clinical factors but not the serumlectin profile remained an independent predictor of CSI. Prior episode of CSI and in a stepwise manner, the disease severity as rated byChild-Pugh stage conferred higher risk for development of CSI (HR: 2.64, 95% CI: 1.74?3.99, p < 0.001 and 2.11, 95%CI: 1.52-2.93, p < 0.001,respectively).In the present prospective study, diseases severity and prior episode of CSI but not the serum lectin profile were major determinants ofthe risk of CSI in cirrhosis.

Megjegyzések:Background: Intravenous thrombolysis (IVT) improves acute ischemic stroke (AIS) outcomes, but with limited success. In addition, ethanol potentiates the effect of r-tPA in ischemia models. Methods: The effect of acute alcohol consumption on IVT outcomes was investigated in a retrospective cohort study. AIS patients with detectable blood alcohol concentration (BAC) during IVT were included (alcohol group; n = 60). For each case, 3 control subjects who underwent IVT but denied alcohol consumption were matched in terms of age, sex, affected brain area, and stroke severity. Outcomes were determined using the NIHSS at 7 days and the modified Rankin scale (mRS) at 90 days. Results: Patients were younger and had a less severe stroke than in a standard stroke study. Favorable long-term outcomes (mRS 0?2) occurred significantly more frequently in the alcohol group compared to controls (90% vs. 63%, p < 0.001). However, the rates of hemorrhagic transformation were similar. Multiple logistic regression models identified elevated BAC as a significant protective factor against unfavorable short-term (OR: 0.091, 95% CI: 0.036?0.227, p < 0.001) and long-term outcomes (OR: 0.182, 95% CI: 0.062?0.535, p = 0.002). In patients with BAC > 0.2%, significantly lower NIHSS was observed at 3 and 7 days after IVT vs. in those with 0.01?0.2% ethanol levels. Conclusion: Elevated BAC is associated with improved outcomes in IVT-treated AIS without affecting safety.
