Monocytes and cells of the dendritic cell lineage circulate in blood and eventually migrate into tissue where they further mature and serve various functions, most notably in immune defense. Over recent years these cells have been characterized in detail with the use of cell surface markers and flow cytometry, and subpopulations have been described. The present document proposes a nomenclature for these cells and defines 3 types of monocytes (classical, intermediate, and nonclassical monocytes) and 3 types of dendritic cells (plasmacytoid and 2 types of myeloid dendritic cells) in human and in mouse blood. This classification has been approved by the Nomenclature Committee of the International Union of Immunological Societies, and we are convinced that it will facilitate communication among experts and in the wider scientific community.

CONTEXT: The expression and release of tissue factor is a major trigger for the activation of coagulation in patients with sepsis. Tissue factor pathway inhibitor (TFPI) forms a complex with tissue factor and blood protease factors leading to inhibition of thrombin generation and fibrin formation. OBJECTIVES: To determine if administration of tifacogin (recombinant TFPI) provides mortality benefit in patients with severe sepsis and elevated international normalized ratio (INR) and to assess tifacogin safety in severe sepsis, including patients with low INR. DESIGN AND SETTING: A randomized, double-blind, placebo-controlled, multicenter, phase 3 clinical trial conducted from March 21, 2000, through September 27, 2001, in 245 hospitals in 17 countries in North America, Europe, and Israel. PATIENTS: The primary efficacy population consisted of 1754 patients (> or =18 years) with severe sepsis and a high INR (> or =1.2) randomly assigned to intravenous infusion of either tifacogin (0.025 mg/kg per hour for 96 hours, n = 880) or placebo (arginine citrate buffer, n = 874), and 201 patients with a low INR (<1.2) randomly assigned to receive the same dose of either tifacogin or placebo. MAIN OUTCOME MEASURE: All-cause 28-day mortality. RESULTS: Overall mortality at 28 days in the tifacogin-treated group (n = 880) vs the placebo group (n = 874) for high INR was 34.2% vs 33.9%, respectively (P =.88, Pearson chi2 test; P =.75, logistic regression model). None of the protocol-specified secondary end points differed between the tifacogin vs placebo groups. An analysis on the first 722 patients demonstrated a mortality rate of 38.9% for placebo vs 29.1% for tifacogin (P =.006, Pearson chi2 test). Tifacogin significantly attenuated prothrombin fragment 1.2 and thrombin:antithrombin complex levels (P<.001, 2-sample t test) in patients with high and low INR. Overall mortality was lower in the tifacogin response in patients with low INR (12%; n = 83) vs placebo (22.9%; n = 118) (P =.051, Pearson chi2 test; P =.03, logistic regression model). There was an increase in serious adverse events with bleeding in the tifacogin group in both cohorts (6.5% tifacogin and 4.8% placebo for high INR; 6.0% tifacogin and 3.3% placebo for low INR). CONCLUSIONS: Treatment with tifacogin had no effect on all-cause mortality in patients with severe sepsis and high INR. Tifacogin administration was associated with an increase in risk of bleeding, irrespective of baseline INR.

PURPOSE: To compare the effectiveness and tolerability of gemcitabine plus cisplatin with single-agent gemcitabine as first-line chemotherapy for locally advanced or metastatic pancreatic cancer. PATIENTS AND METHODS: Patients with advanced adenocarcinoma of the pancreas were randomly assigned to receive either gemcitabine 1,000 mg/m2 and cisplatin 50 mg/m2 given on days 1 and 15 of a 4-week cycle (GemCis arm) or gemcitabine alone at a dose of 1,000 mg/m2 on days 1, 8, and 15 of a 4-week regimen (Gem arm). The primary end point was overall survival; secondary end points were progression-free survival, response rate, safety, and quality of life. RESULTS: One hundred ninety-five patients were enrolled and showed baseline characteristics well balanced between treatment arms. Combination treatment in the GemCis arm was associated with a prolonged median progression-free survival (5.3 months v 3.1 months; hazard ratio [HR] = 0.75; P = .053). Also, median overall survival was superior for patients treated in the GemCis arm as compared with the Gem arm (7.5 v 6.0 months), an advantage which did not, however, reach statistical significance (HR = 0.80; P = .15). Tumor response rates were comparable between treatment arms (10.2% v 8.2%). The rate of stable disease was, however, greater in the combination arm (60.2% v 40.2%; P < .001). Grade 3 to 4 hematologic toxicity did not exceed 15% in both treatment arms. CONCLUSION: These results support the efficacy and safety of an every-2-weeks treatment with gemcitabine plus cisplatin. Median overall survival and progression-free survival were more favorable in the combination arm as compared with gemcitabine alone, although the difference did not attain statistical significance.

BACKGROUND: Our aim was to assess the mortality and vascular morbidity risk of elderly individuals with asymptomatic versus symptomatic peripheral artery disease (PAD) in the primary care setting. METHODS AND RESULTS: This prospective cohort study included 6880 representative unselected patients >or=65 years of age with monitored follow-up over 5 years. According to physician diagnosis, 5392 patients had no PAD, 836 had asymptomatic PAD (ankle brachial index <0.9 without symptoms), and 593 had symptomatic PAD (lower-extremity peripheral revascularization, amputation as a result of PAD, or intermittent claudication symptoms regardless of ankle brachial index). The risk of symptomatic compared with asymptomatic PAD patients was significantly increased for the composite of all-cause death or severe vascular event (myocardial infarction, coronary revascularization, stroke, carotid revascularization, or lower-extremity peripheral vascular events; hazard ratio, 1.48; 95% confidence interval, 1.21 to 1.80) but not for all-cause death alone (hazard ratio, 1.13; 95% confidence interval, 0.89 to 1.43), all-cause death/myocardial infarction/stroke (excluding lower-extremity peripheral vascular events and any revascularizations; hazard ratio, 1.18; 95% confidence interval, 0.92 to 1.52), cardiovascular events alone (hazard ratio, 1.20; 95% confidence interval, 0.89 to 1.60), or cerebrovascular events alone (hazard ratio, 1.33; 95% confidence interval, 0.80 to 2.20). Lower ankle brachial index categories were associated with increased risk. PAD was a strong factor for the prediction of the composite end point in an adjusted model. CONCLUSIONS: Asymptomatic PAD diagnosed through routine screening in the offices of primary care physicians carries a high mortality and/or vascular event risk. Notably, the risk of mortality was similar in symptomatic and asymptomatic patients with PAD and was significantly higher than in those without PAD. In the primary care setting, the diagnosis of PAD has important prognostic value.

BACKGROUND AND OBJECTIVES: performing neuraxial anaesthesia in patients receiving antithrombotic drugs is controversial due to the increased risk of spinal epidural haematoma. Strict adherence to the recommended time intervals between the administration of anticoagulants, neuraxial blockade and the removal of catheters is thought to improve patient safety and reduce the risk of haematoma. Appropriate guidelines have been prepared by a number of national societies of anaesthesiologists, but they do not have universal acceptance. The introduction of new anticoagulants together with recent reports of stent thrombosis in patients with perioperative cessation of antiplatelet drugs have considerably broadened the issue and made revision necessary. To overcome deficiencies in content and applicability, the European Society of Anaesthesiology has taken the initiative to provide current and comprehensive guidelines for the continent as a whole. METHODS: extensive review of the literature. RESULTS AND CONCLUSIONS: in order to minimise bleeding complications during regional anaesthetic techniques, care should be taken to avoid traumatic puncture. If a bloody tap occurs when intraoperative anticoagulation is planned, postponing surgery should be considered. Alternatively, catheters can be placed the night before surgery. Regional anaesthesia in patients receiving full anticoagulation treatment continues to be contraindicated. Catheter manipulation and removal carry similar risks to insertion and the same criteria should apply. Appropriate neurological monitoring is essential during the postoperative recovery period and following catheter removal. The final decision to perform regional anaesthesia in patients receiving drugs that affect haemostasis has to be taken after careful assessment of individual risks and benefits.

The Committee on Nutrition of the European Society for Pediatric Gastroenterology, Hepatology, and Nutrition aims to document the existing evidence of the benefits and common concerns deriving from the use of donor human milk (DHM) in preterm infants. The comment also outlines gaps in knowledge and gives recommendations for practice and suggestions for future research directions. Protection against necrotizing enterocolitis is the major clinical benefit deriving from the use of DHM when compared with formula. Limited data also suggest unfortified DHM to be associated with improved feeding tolerance and with reduced cardiovascular risk factors during adolescence. Presence of a human milk bank (HMB) does not decrease breast-feeding rates at discharge, but decreases the use of formula during the first weeks of life. This commentary emphasizes that fresh own mother's milk (OMM) is the first choice in preterm infant feeding and strong efforts should be made to promote lactation. When OMM is not available, DHM is the recommended alternative. When neither OMM nor DHM is available, preterm formula should be used. DHM should be provided from an established HMB, which follows specific safety guidelines. Storage and processing of human milk reduces some biological components, which may diminish its health benefits. From a nutritional point of view, DHM, like HM, does not meet the requirements of preterm infants, necessitating a specific fortification regimen to optimize growth. Future research should focus on the improvement of milk processing in HMB, particularly of heat treatment; on the optimization of HM fortification; and on further evaluation of the potential clinical benefits of processed and fortified DHM.

In order to evaluate the prophylactic effect of oral magnesium, 81 patients aged 18-65 years with migraine according to the International Headache Society (IHS) criteria (mean attack frequency 3.6 per month) were examined. After a prospective baseline period of 4 weeks they received oral 600 mg (24 mmol) magnesium (trimagnesium dicitrate) daily for 12 weeks or placebo. In weeks 9-12 the attack frequency was reduced by 41.6% in the magnesium group and by 15.8% in the placebo group compared to the baseline (p < 0.05). The number of days with migraine and the drug consumption for symptomatic treatment per patient also decreased significantly in the magnesium group. Duration and intensity of the attacks and the drug consumption per attack also tended to decrease compared to placebo but failed to be significant. Adverse events were diarrhea (18.6%) and gastric irritation (4.7%). High-dose oral magnesium appears to be effective in migraine prophylaxis.

PURPOSE: To describe the safety and efficacy of high-intensity focused ultrasound (HIFU) for the treatment of prostate cancer as assessed in a Phase II/III prospective multicentric clinical trial. PATIENTS AND METHODS: Patients (N = 402) presenting with localized (stage T(1-2)N(0-x)M(0)) prostate cancer between 1995 and 1999 at six European sites who were not candidates for radical prostatectomy were treated with HIFU under general or spinal anesthesia. Their mean age was 69.3 +/- 7.1 (SD) years, the mean prostate volume 28.0 +/- 13.8 cc, and the mean serum prostate specific antigen (PSA) concentration 10.9 +/- 8.7 ng/mL. Nearly all (92.2%) of the patients had one to four positive biopsy samples at baseline. The Gleason scores were 2 to 4 for 13.2% of the patients, 5 to 7 for 77.5%, and 8 to 10 for 9.3%. During the follow-up, random sextant biopsies and serum PSA measurements were performed. Any positive sample in biopsies performed after the last treatment session resulted in a "HIFU failure" classification. RESULTS: The patients received a mean of 1.4 HIFU sessions. The mean follow-up duration was 407 days (quartile 1 135 days, median 321 days, quartile 3 598 days). The negative biopsy rate observed in the T1-2 primary-care population was 87.2%. These results were also stratified according to the usual disease-related risk classification, and as much as a 92.1% negative biopsy rate was observed in low-risk patients. Nadir PSA results correlated with prostate size and the clinical procedure. CONCLUSION: These short-term results obtained on a large cohort confirm that HIFU is an option to be considered for the primary treatment of localized prostate cancer.

BACKGROUND AND PURPOSE: Systemic thrombolysis represents the only proven therapy for acute ischemic stroke, but safe treatment is reported only in established stroke units. One major goal of the ongoing Telemedic Pilot Project for Integrative Stroke Care (TEMPiS) in Bavaria is to extend the use of tissue plasminogen activator (tPA) treatment in nonurban areas through telemedic support. METHODS: The stroke centers in Munich-Harlaching and in Regensburg established a telestroke network to provide consultations for 12 local hospitals in eastern Bavaria. The telemedic system consists of a digital network that includes a 2-way video conference system and CT/MRI image transfer with a high-speed data transmission up to 2 Mb/s. Each network hospital established specialized stroke wards in which qualified teams treat acute stroke patients. Physicians in these hospitals are able to contact the stroke centers 24 hours per day. RESULTS: A total of 106 systemic thrombolyses were indicated via teleconsultations between February 1, 2003, and April 7, 2004. During the first 12 months, the rate of thrombolyses was 2.1% of all stroke patients. Mean age was 68 years, and median National Institutes of Health Stroke Scale score was 13. Mean delay between onset and hospital admission was 65 minutes, and door-to-needle time was on average 76 minutes, which included 15 minutes for the teleconsultation. Symptomatic hemorrhage occurred in 8.5% of patients, and in-hospital mortality was 10.4%. CONCLUSIONS: The present data suggest that systemic thrombolysis indicated via stroke experts in the setting of teleconsultation exhibits similar complication rates to those reported in the National Institute of Neurological Disorders and Stroke trial. Therefore, tPA treatment is also safe in this context and can be extended to nonurban areas.

OBJECTIVE: Intravenous immunoglobulin as an adjunctive treatment in sepsis was regarded as promising by a Cochrane meta-analysis of smaller trials. In this phase III multicenter trial, we assessed whether intravenous immunoglobulin G (ivIgG) reduced 28-day mortality and improved morbidity in patients with score-defined severe sepsis. DESIGN: Randomized, double-blind, placebo-controlled, multicenter trial. SETTING: Twenty-three medical and surgical intensive care units in university centers and large teaching hospitals. PATIENTS: Patients (n = 653) with score-defined sepsis (sepsis score 12-27) and score-defined sepsis-induced severity of disease (Acute Physiology and Chronic Health Evaluation II score 20-35). INTERVENTIONS: Patients were assigned to receive either placebo or ivIgG (day 0, 0.6 g/kg body weight; day 1, 0.3 g/kg body weight). MEASUREMENTS AND MAIN RESULTS: The prospectively defined primary end point was death from any cause after 28 days. Prospectively defined secondary end points were 7-day all-cause mortality, short-term change in morbidity, and pulmonary function at day 4. Six hundred fifty-three patients from 23 active centers formed the intention-to-treat group, 624 patients the per-protocol group (placebo group, n = 303; ivIgG group, n = 321). The 28-day mortality rate was 37.3% in the placebo group and 39.3% in the ivIgG group and thus not significantly different (p = .6695). Seven-day mortality was not reduced, and 4-day pulmonary function was not improved. Drug-related adverse events were rare in both groups. Exploratory findings revealed a 3-day shortening of mechanical ventilation in the surviving patients and no effect of ivIgG on plasma levels of interleukin-6 and tumor necrosis factor receptors I and II. CONCLUSIONS: In patients with score-defined severe sepsis, ivIgG with a total dose of 0.9 g/kg body weight does not reduce mortality.

BACKGROUND AND PURPOSE: Recent studies suggest an association of coronary heart disease and carotid atherosclerosis with Chlamydia pneumoniae infection. We investigated the frequency of chlamydial seropositivity and specific circulating immune complexes in patients with recent cerebrovascular disease. METHODS: Specific antibodies to C pneumoniae in serum were measured by the microimmunofluorescence test in 58 consecutive patients (aged 18 to 50 years) with ischemic infarction (n = 39) or transient ischemic attacks (n = 19) and in 52 hospital control subjects without vascular disease, matched for sex, age, time, and locality. RESULTS: Twenty-seven patients (46.6%) and 12 control subjects (23.1%) had raised IgA titers > or = 1:16 (P = .018). IgG titers > or = 1:32 were measured in 74.1% of the patients and 77% of control subjects (P = .623). Specific IgG antibodies in circulating immune complexes, which were isolated by polyethylene glycol precipitation, were elevated > or = 1:8 in 24.1% of the patients and 7.7% of control subjects (P = .047). With the use of a conditional logistic regression model, the odds ratios were 1.70 (95% confidence interval [CI], 1.13 to 2.58) for elevated IgA titers, 1.91 (95% CI, 1.06 to 3.47) for the presence of immune complexes, and 1.96 (95% CI, 1.00 to 3.82) for the presence of both factors. After adjustment for the vascular risk factors hypertension, age, sex, and migraine, the odds ratios were 1.71 (95% CI, 1.08 to 2.70), 2.00 (95% CI, 1.07 to 3.76), and 2.20 (95% CI, 1.09 to 4.41), respectively. CONCLUSIONS: We conclude that chronic infection with C pneumoniae is associated with an increased risk of stroke and transient ischemic events.

Insulin-like growth factor (IGF)-binding protein-2 (IGFBP-2) has been shown to inhibit IGF-dependent cell proliferation in a number of in vitro studies. However, no in vivo model of IGFBP-2 overexpression has been established so far. Therefore, we have generated transgenic mice, in which expression of a mouse IGFBP-2 complementary DNA is controlled by the cytomegalovirus (CMV) promoter. In two independent transgenic strains, transgene expression was highest in pancreas and stomach, followed by skeletal muscle, heart, colon, spleen, adipose tissue, brain, and kidney. Within the pancreas, IGFBP-2 expression was found in the islets but not in the exocrine part. Serum IGFBP-2 levels of CMV-IGFBP-2 transgenic mice were about 3-fold (P < 0.05) increased, compared with controls, whereas serum levels of IGF-I and IGF-II were unaffected by IGFBP-2 overexpression. Fasted serum glucose and fasted insulin levels were slightly reduced in transgenic mice, compared with controls. Postprandial serum glucose insulin levels were not affected by the genotype. At days later than 23, body weights of transgenic mice were significantly (P < 0.05) reduced in both sexes, compared with nontransgenic littermates. This reduction in body weight was mainly attributable to significantly (P < 0.05) lower carcass weights of CMV-IGFBP-2 transgenic vs. control mice. In contrast, absolute organ weights were not (or only as a tendency) reduced, except for the weight of the spleen, which was significantly (P < 0.05) lower in male transgenic than in control mice. Our data suggest that IGFBP-2 represents a negative regulator of postnatal growth in mice, potentially by reducing the bioavailability of IGF-I.

BACKGROUND: IV thrombolysis represents the most effective acute stroke therapy. However, it is almost exclusively performed in stroke centers and is not available in most community areas. The Telemedical Pilot Project for Integrative Stroke Care (TEMPiS) was started in February 2003. Twelve community hospitals with no or very limited stroke thrombolysis experience and two stroke centers were connected via a network providing online neurologic examination and transfer of neuroradiologic scans. Following recently published preliminary results on acute phase safety of telethrombolysis, the present study reports on its long-term functional outcome. METHODS: Modified Rankin Scale (mRS), Barthel Index (BI), and mortality rate were prospectively collected 3 and 6 months after IV thrombolysis in patients of community network hospitals (telemedical group) and the stroke centers. Values of 95/100 for the BI and 0/1 for the mRS were defined as a favorable outcome. RESULTS: Over the first 22 months, 170 patients were treated with tPA in the telemedical hospitals and 132 in the stroke center hospitals. Mortality rates were 11.2% vs 11.5% at 3 months (p = 0.55) and 14.2% vs 13% at 6 months (p = 0.45). A good functional outcome after 6 months was found in 39.5% of the telemedical hospitals vs 30.9% of the stroke centers (p = 0.10) for the mRS and 47.1% vs 44.8% (p = 0.44) regarding the BI. CONCLUSIONS: Mortality rates and functional outcomes for telemedicine-linked community hospitals and stroke centers were similar and comparable to the results from randomized trials.

ABSTRACT Infections are frequent complications in end-stage renal failure patients undergoing hemodialysis (HD), and peripheral blood monocytes are important cells in host defense against infections. The majority of circulating monocytes express high levels of lipopolysaccharide receptor antigen CD14 and are negative for the immunoglobulin Fcγ receptor type III (CD16). We studied the occurrence of a minor subpopulation coexpressing low levels of CD14 together with CD16 in HD patients. In healthy controls CD14 + CD16 + monocytes account for 8% ± 4% of CD14 + monocytes, with an absolute number of 29 ± 14 cells/μl. In stable HD patients the CD14 + CD16 + subpopulation was significantly elevated (14% ± 3%, or 66 ± 28 cells/μl), while the number of CD14 ++ monocytes (monocytes strongly positive for CD14) remained constant. In HD patients suffering from chronic infections a further rise in CD14 + CD16 + monocytes was observed (128 ± 71 cells/μl; P &lt; 0.01) such that this subpopulation constituted 24% of all blood monocytes. In contrast, numbers of CD14 ++ cells did not change compared to those for stable HD patients, indicating that the CD14 + CD16 + monocyte subpopulation was selectively expanded. During acute infections the CD14 + CD16 + cell subpopulation always expanded. A whole-blood assay revealed that CD14 + CD16 + monocytes exhibited a higher phagocytosis rate for Escherichia coli bacteria than CD14 ++ monocytes, underlining their role during host defense. In addition, CD14 + CD16 + monocytes expressed higher levels of major histocompatibility complex (MHC) class II antigens (HLA-DR, -DP, and -DQ) and equal amounts of MHC class I antigens (HLA-ABC). Thus, CD14 + CD16 + cells constitute a potent phagocytosing and antigen-presenting monocyte subpopulation, which is expanded during acute and chronic infections commonly observed in chronic HD patients.

BACKGROUND AND PURPOSE: Systemic thrombolysis is the only therapy proven to be effective for ischemic stroke. Telemedicine may help to extend its use. However, concerns remain whether management and safety of tissue plasminogen activator (tPA) administration after telemedical consultation are equivalent in less experienced hospitals compared with tPA administration in academic stroke centers. METHODS: During the second year of the ongoing Telemedical Pilot Project for Integrative Stroke Care, all systemic thrombolyses in stroke patients of the 12 regional clinics and the 2 stroke centers were recorded prospectively. Patients' demographics, stroke severity (National Institutes of Health Stroke Scale), frequency of administration, time management, protocol violations, and safety were included in the analysis. RESULTS: In 2004, 115 of 4727 stroke or transient ischemic attack patients (2.4%) in the community hospitals and 110 of 1889 patients in the stroke centers (5.8%) received systemic thrombolysis. Prehospital latencies were shorter in the regional hospitals despite longer distances. Door to needle times were shorter in the stroke centers. Although blood pressure was controlled more strictly in community hospitals, symptomatic intracerebral hemorrhage rate (7.8%) was higher (P=0.14) than in stroke centers (2.7%) but still within the range of the National Institute of Neurological Disorders and Stroke trial. In-hospital mortality rate was low in community hospitals (3.5%) and in stroke centers (4.5%). CONCLUSIONS: Although with a lower rate of systemic thrombolysis, there was no evidence of lower treatment quality in the remote hospitals. With increasing numbers of tPA administration and growing training effects, the telestroke concept promises better coverage of systemic thrombolysis in nonurban areas.

Fever may be the only clinical symptom at the onset of infection in neutropenic cancer patients undergoing myelosuppressive chemotherapy. A prompt and evidence-based diagnostic and therapeutic approach is mandatory. A systematic search of current literature was conducted, including only full papers and excluding allogeneic hematopoietic stem cell transplant recipients. Recommendations for diagnosis and therapy were developed by an expert panel and approved after plenary discussion by the AGIHO. Randomized clinical trials were mainly available for therapeutic decisions, and new diagnostic procedures have been introduced into clinical practice in the past decade. Stratification into a high-risk versus low-risk patient population is recommended. In high-risk patients, initial empirical antimicrobial therapy should be active against pathogens most commonly involved in microbiologically documented and most threatening infections, including Pseudomonas aeruginosa, but excluding coagulase-negative staphylococci. In patients whose expected duration of neutropenia is more than 7 days and who do not respond to first-line antibacterial treatment, specifically in the absence of mold-active antifungal prophylaxis, further therapy should be directed also against fungi, in particular Aspergillus species. With regard to antimicrobial stewardship, treatment duration after defervescence in persistently neutropenic patients must be critically reconsidered and the choice of anti-infective agents adjusted to local epidemiology. This guideline updates recommendations for diagnosis and empirical therapy of fever of unknown origin in adult neutropenic cancer patients in light of the challenges of antimicrobial stewardship.

OBJECTIVE: To compare the effectiveness of controlled-released carbamazepine (CR-CBZ) to levetiracetam (LEV) and to lamotrigine (LTG) in elderly patients with newly diagnosed focal epilepsy. METHODS: Randomized, double-blind, parallel-group trial conducted between January 2007 and August 2011, in 47 ambulatory or hospital sites in Germany, Austria, or Switzerland. Eligible participants were aged ≥ 60, had new-onset epilepsy, had no acute illness as the cause of their seizures, and had no contraindication to the drugs in the trial. Patients were randomized 1:1:1 to CR-CBZ, LTG, or LEV. Doses were up-titrated for 6 weeks and could be maintained or adjusted depending on seizure relapse or tolerability over an additional period of 52 weeks. Primary outcome was the retention to treatment at week 58; secondary measures related to seizure and adverse event frequency. RESULTS: Of 361 randomized patients, 359 were included (CR-CBZ n = 121, LTG n = 117, LEV n = 122) in the modified intent-to-treat population (mean age [range] 71.4 [60-95] years). At week 58, the retention rate for LEV was significantly higher than for CR-CBZ (61.5% vs. 45.8%, p = 0.02), and similar to LTG (55.6%). Seizure freedom rates at weeks 30 and 58 were not different across the groups. Twice as many patients receiving CR-CBZ discontinued due to adverse events or death compared to those in the LEV group (32.2% vs. 17.2%; odds ratio 2.28, 95% confidence interval [CI] 1.25-4.19, p = 0.007), whereas discontinuation was intermediate for LTG (26.3%). Median daily doses of completers (n = 195) were CR-CBZ 380.0 mg/day (333.0-384.0), LTG 95 mg/day (94.0-97.0), and LEV 950 mg/day (940.0-985.0). SIGNIFICANCE: In the initial monotherapy of focal epilepsy in the elderly, 1-year retention to LEV was higher compared to CR-CBZ due to better tolerability. Retention of LTG was intermediate and close to LEV, but did not differ significantly from either comparators. NCT00438451, www.clinicaltrials.gov.

A phase 2 trial was performed to study the combination of bortezomib (VELCADE) with intermediate-dose dexamethasone (DEX), and continuous low-dose oral cyclophosphamide (CY) in patients with relapsed multiple myeloma (MM). Fifty-four patients with advanced MM were enroled to receive eight 3-week treatment cycles with bortezomib 1.3 mg/m(2) on days 1, 4, 8, and 11, followed by three 5-week cycles with bortezomib 1.3 mg/m(2) on days 1, 8, 15, and 22. Within all cycles, DEX 20 mg/d was given orally on the day of bortezomib injection and the day thereafter. In addition, patients received CY continuous oral treatment at a dose of 50 mg/d p.o. once daily. Fifty patients completing at least one treatment cycle were evaluable for response. Complete, partial, and minor responses occurred in 16%, 66% and 8% of patients, respectively; overall response rate 90% (efficacy analysis). Median event-free survival was 12 months, with a median overall survival of 22 months. Adverse events (AE) of grades 3 or 4 occurring in at least 10% of patients comprised leucopenia, infection, herpes zoster, thrombocytopenia, neuropathy and fatigue. Bortezomib combined with DEX and CY is a highly effective treatment for relapsed MM at an acceptable rate of grade 3/4 AE. Antiviral prophylaxis appears to be mandatory.

BACKGROUND AND PURPOSE: To determine whether body temperature, c-reactive protein (CRP), and white blood cell (WBC) count within the first days after stroke onset correlate with infarct size and stroke severity, and to examine whether successful thrombolysis reduces poststroke inflammation. METHODS: Out of 1500 consecutive acute ischemic stroke patients, 346 cases (43 patients with thrombolysis) were selected according to the following criteria: admission to hospital < or =24 hours after event, absence of prestroke and poststroke infectious disease, no intracerebral hemorrhage or brain stem stroke, and data availability. Body temperature, WBC within 3 days, and CRP within 5 days of event were determined daily. Lesion volume was measured by planimetry on computed tomography or MRI scans. Successful thrombolysis was defined as improvement on the National Institutes of Health Stroke Scale of > or =4 points within 24 hours. RESULTS: Increase of inflammatory parameters correlated significantly with lesion volume and stroke severity. This was shown for body temperature on days 2 and 3 (P<0.001), CRP on days 1 to 5 (P<0.05), and WBC on days 1 to 3 (P<0.01). Patients with successful thrombolysis had reduced body temperature on day 3, WBC on days 2 and 3, and CRP on days 3 to 5 (P<0.05). CONCLUSIONS: Patients with a larger stroke volume and more severe stroke deficits have higher body temperature, CRP, and WBC count in the acute phase after stroke. Successful thrombolysis is related to a significantly attenuated inflammatory response.

Background The high cardiovascular morbidity and mortality of patients with CKD may result in large part from medial vascular calcification, a process promoted by hyperphosphatemia and involving osteo-/chondrogenic transdifferentiation of vascular smooth muscle cells (VSMCs). Reduced serum zinc levels have frequently been observed in patients with CKD, but the functional relevance of this remains unclear. Methods We performed experiments in primary human aortic VSMCs; klotho-hypomorphic ( kl/kl ), subtotal nephrectomy, and cholecalciferol-overload mouse calcification models; and serum samples from patients with CKD. Results In cultured VSMCs, treatment with zinc sulfate (ZnSO 4 ) blunted phosphate-induced calcification, osteo-/chondrogenic signaling, and NF- κ B activation. ZnSO 4 increased the abundance of zinc-finger protein TNF- α –induced protein 3 (TNFAIP3, also known as A20), a suppressor of the NF- κ B pathway, by zinc-sensing receptor ZnR/GPR39-dependent upregulation of TNFAIP3 gene expression. Silencing of TNFAIP3 in VSMCs blunted the anticalcific effects of ZnSO 4 under high phosphate conditions. kl/kl mice showed reduced plasma zinc levels, and ZnSO 4 supplementation strongly blunted vascular calcification and aortic osteoinduction and upregulated aortic Tnfaip3 expression. ZnSO 4 ameliorated vascular calcification in mice with chronic renal failure and mice with cholecalciferol overload. In patients with CKD, serum zinc concentrations inversely correlated with serum calcification propensity. Finally, ZnSO 4 ameliorated the osteoinductive effects of uremic serum in VSMCs. Conclusions Zinc supplementation ameliorates phosphate-induced osteo-/chondrogenic transdifferentiation of VSMCs and vascular calcification through an active cellular mechanism resulting from GPR39-dependent induction of TNFAIP3 and subsequent suppression of the NF- κ B pathway. Zinc supplementation may be a simple treatment to reduce the burden of vascular calcification in CKD.
