Abstract
Zusammenfassung
Gegenstand und Ziel: Um Sekretionsstörungen der bovinen Milchdrüse bereits frühzeitig in praxi identifizieren zu können, ist es notwendig, ein Testsystem mit einer hohen Sensitivität einzusetzen. Im Rahmen der vorliegenden Studie sollte daher untersucht werden, inwieweit durch die Verwendung eines Reagenz mit einer optimierten Rezeptur die Sensitivität des California-Mastitis-Tests im Vergleich zu einem kommerziell verfügbaren Produkt verbessert werden kann, sodass sich bereits Überschreitungen der Zellzahl von 100.000 Zellen/ml sicher erkennen lassen. Material und Methoden: In vitro wurden die Viskositäten von Gemischen aus Testmilchen mit standardisierten somatischen Zellgehalten (50.000-800.000 Zellen/ml) und Testreagenzien bestimmt. Insgesamt 50 Viertelanfangsgemelksproben von Tieren, die keine Anzeichen einer klinischen Mastitis aufwiesen, wurden geblindet mit dem California-Mastitis-Test unter Verwendung beider Testreagenzien untersucht. Sensitivität und Spezifität der Testsysteme wurden ermittelt. Ergebnisse: Mit zunehmendem somatischem Zellgehalt stieg die Viskosität der Gemische zu Beginn der rheologischen Messung. Bei einem Zellgehalt der Milch von 50.000 Zellen/ml ergab sich eine mittlere Viskosität von 3,20 mPa*s (kommerziell verfügbarer Test) bzw. 2,69 mPa*s (optimiertes Testreagens). Bei einem Milchzellgehalt von 100.000 Zellen/ml stieg die Viskosität auf 3,43 mPa*s (kommerziell verfügbarer Test) bzw. 4,58 mPa*s (optimiertes Testreagens) an. Die Sensitivität betrug bei Verwendung des kommerziell verfügbaren Testreagens 76,7% und unter Einsatz des optimierten Testreagens 97,7% bei einer Zellzahlgrenze von 100.000 Zellen/ml als Übergang vom physiologischen Zustand zu einer Sekretionsstörung. Schlussfolgerung und klinische Relevanz: Das optimierte Testreagens erlaubt im Vergleich zu dem kommerziell verfügbaren Reagens die frühzeitige Erkennung zellzahlhoher Viertel bzw. Tiere. Die Ergebnisse machten deutlich, dass das Ablesen des Testresultats direkt nach der Reaktion erfolgen muss.

Abstract
OBJECTIVE For the early detection of udder health disorders in praxi, it is necessary to use a method with high sensitivity. The aim of the present study was to investigate the sensitivity of a commercial Califor- nia Mastitis Test and a new reagent which was optimised for the detection of udder health disorders with somatic cell counts > 100,000 cells/ml. MATERIAL AND METHODS The viscosity of mixtures of test milks with standardised somatic cell counts (50,000-800,000 cells/ml) and test reagents were analysed in vitro. A total of 50 quarter fore- milk samples from cows without signs of clinical mastitis were investigated using both California Mastitis Test reagents. Sensitivity and specificity were calculated. RESULTS The viscosity of mixtures increased with a higher somatic cell count. At a somatic cell count of 50,000 cells/ml, the mean viscosities were 3.20 mPa*s (commer- cial product) and 2.69 mPa*s (optimised reagent). At a somatic cell count of 100,000 cells/ml the viscosities increased to 3.43 mPa*s and 4.58 mPa*s, respectively. At a somatic cell count threshold of 100,000 cells/ml, marking the transition of the physiological status into a secretion disorder, the sensitivity of the commercial test was 76.7% and that of the optimised test was 97.7%. CONCLUSION AND CLINICAL RELEVANCE The optimised California Mastitis Test allows - compared to the commercial product - the early detection of quarters or animals with high somatic cell counts. The results of the study indicate that the test result has to be evaluated immediately after the California Mastitis Test reaction.

Abstract
The most common manifestation of plasma cell neoplasms is multiple myeloma. Solitary and localized tumours in the form of solitary plasmacytoma of the bone or extramedullary plasmacytoma are rare. In the late stages of multiple myeloma, bulky bone tumour infiltrates may be found which may be the primary clinical manifestation of the previously unknown malignancy. We report a case of a hyoid bone tumour with extramedullary plasma cell infiltrates in the oropharynx in multiple myeloma.

Abstract
Metabolite profiling (metabolomics) elucidates changes in biochemical pathways under various conditions, e.g., different nutrition scenarios or compound administration. BASF and metanomics have obtained plasma metabolic profiles of approximately 500 compounds (agrochemicals, chemicals and pharmaceuticals) from 28-day rat studies. With these profiles the establishment of a database (MetaMap(®)Tox) containing specific metabolic patterns associated with many toxicological modes of action was achieved. To evaluate confounding factors influencing metabolome patterns, the effect of fasting vs. non-fasting prior to blood sampling, the influence of high caloric diet and caloric restriction as well as the administration of corn oil and olive oil was studied for its influence on the metabolome. All mentioned treatments had distinct effects: triacylglycerol, phospholipids and their degradation product levels (fatty acids, glycerol, lysophosphatidylcholine) were often altered depending on the nutritional status. Also some amino acid and related compounds were changed. Some metabolites derived from food (e.g. alpha-tocopherol, ascorbic acid, beta-sitosterol, campesterol) were biomarkers related to food consumption, whereas others indicated a changed energy metabolism (e.g. hydroxybutyrate, pyruvate). Strikingly, there was a profound difference in the metabolite responses to diet restriction in male and female rats. Consequently, when evaluating the metabolic profile of a compound, the effect of nutritional status should be taken into account.

Abstract
ABSTRACTPolymers are currently considered as a possible alternative to silicon dioxide in the fabrication of interlevel dielectrics. To penetrate mainstream semiconductor device fabrication polymers have to meet a number of requirements regarding their long-term stability. One aspect is the mechanical stability of integrated polymer films under changing climatic conditions. In the present work, the impact of ambient moisture on the mechanical properties of thin polymer films (PI, BCB, and PFCB) was investigated. The sorption of water molecules in these materials typically causes an anisotropic volume expansion, resulting in increased mechanical film stress if the film is physically constrained by adjacent inorganic structures. Especially polyimides show both considerable moisture uptake and large changes in the mechanical film stress, while BCB and PFCB are virtually insensitive to ambient moisture. In the paper, experimental data (water uptake, in-plane swelling, out-of-plane swelling) are presented and discussed in detail.

Abstract
Several studies have investigated the potential of various autoantibody tests in the diagnosis of systemic lupus erythematosus (SLE). Many lupus patients initially present with glomerulonephritis. In that clinical situation the main differential diagnosis are other forms of glomerulonephritis. In this study the diagnostic value of nine test kits for autoantibody against ANA, dsDNA, circulating immune complexes, C1q, nucleosomes, histones and Sm as well as C3 and C4 levels was evaluated in 39 patients with biopsy-proven lupus nephritis in comparison to 43 patients suffering from other forms of glomerulonephritis. The most useful test was an anti-nucleosome antibody enzyme-linked immunosorbent assay (ELISA) with a sensitivity of 90% and a specificity of 88%. All tests for anti-dsDNA antibodies (Crithidia luciliae Anti-dsDNA, BINDAZYME Anti-dsDNA, FARRZYME high avidity Anti-dsDNA) were of moderate sensitivity and very good specificity. Decreasing the cut-off for the conventional anti-dsDNA ELISA (BINDAZYME) considerably increased its sensitivity (87%) without loss of specificity (90%). Tests for anti-C1q and immune complexes performed worse than the antidsDNA tests. As anti-histone and Sm antibodies are present only in a minority of lupus nephritis patients they are of limited value in diagnosing the disease. In conclusion, testing for anti-nucleosome antibodies and the conventional anti-dsDNA ELISA with lower cut-off provide the best diagnostic aids for differentiation of lupus nephritis from other forms of glomerulonephritis. Lupus (2009) 18, 1276—1280.

Abstract
OBJECTIVE Recommendations and/or guidelines represent a popular way of integrating evidence-based medicine into clinical practice. The 3E Initiatives is a multi-national effort to develop recommendations for the management of rheumatic diseases, which involves a large number of experts combined with practising rheumatologists addressing specific questions relevant to clinical practice. METHODS Ten countries participated in three rounds of discussions and votes concerning the management of AS. A set of nine questions was formulated in the domains of diagnosis, monitoring and treatment, after a Delphi procedure. A literature search in MedLine was conducted. Predefined outcome parameters for the domains of diagnosis, monitoring and treatment were assessed. The evidence to support each proposition was evaluated and scored. After discussion and votes, the final recommendations were presented using brief statements by each national group, following which the final international recommendations were formulated. RESULTS A total of 2699 papers were found and 467 were selected for analysis. Twelve key recommendations were developed: three in the domain of diagnosis addressing general diagnostic considerations, early AS diagnosis and general practitioners' referral recommendations; three concerning monitoring of AS disease activity, severity and prognosis; six concerning pharmacological treatment (except biologics): non-steroidal anti-inflammatory drugs/COX-II inhibitors, bisphosphonates and treatment of enthesitis. The compiled agreement among experts ranged from 72% to 93%. CONCLUSION Recommendations for the management of AS were developed using an evidence-based approach followed by expert/physician consensus with high level of agreement. Involvement of a larger and more representative group of rheumatologists may improve their dissemination and implementation in daily clinical practice.

Abstract
OBJECTIVES To study the clinical outcome, treatment response, T-cell subsets and functional consequences of a novel tumour necrosis factor (TNF) receptor type 1 (TNFRSF1A) mutation affecting the receptor cleavage site. METHODS Patients with symptoms suggestive of tumour necrosis factor receptor-associated periodic syndrome (TRAPS) and 22 healthy controls (HC) were screened for mutations in the TNFRSF1A gene. Soluble TNFRSF1A and inflammatory cytokines were measured by ELISAs. TNFRSF1A shedding was examined by stimulation of peripheral blood mononuclear cells (PBMCs) with phorbol 12-myristate 13-acetate followed by flow cytometric analysis (FACS). Apoptosis of PBMCs was studied by stimulation with TNFalpha in the presence of cycloheximide and annexin V staining. T cell phenotypes were monitored by FACS. RESULTS TNFRSF1A sequencing disclosed a novel V173D/p.Val202Asp substitution encoded by exon 6 in one family, the c.194-14G>A splice variant in another and the R92Q/p.Arg121Gln substitution in two families. Cardiovascular complications (lethal heart attack and peripheral arterial thrombosis) developed in two V173D patients. Subsequent etanercept treatment of the V173D carriers was highly effective over an 18-month follow-up period. Serum TNFRSF1A levels did not differ between TRAPS patients and HC, while TNFRSF1A cleavage from monocytes was significantly reduced in V173D and R92Q patients. TNFalpha-induced apoptosis of PBMCs and T-cell senescence were comparable between V173D patients and HC. CONCLUSIONS The TNFRSF1A V173D cleavage site mutation may be associated with an increased risk for cardiovascular complications and shows a strong response to etanercept. T-cell senescence does not seem to have a pathogenetic role in affected patients.

Abstract
Selenium is an essential trace element and a component of various enzymes with antioxidant functions. High-sensitive C-reactive protein (hsCRP) is an early indicator of increased lipid peroxidation. The serum selenium concentration, lipid parameters, and hsCRP values of gestational diabetic pregnant women (GD), control pregnant women (CP), and healthy nonpregnant controls (HC) were compared. Blood was taken between the 24th and the 28th week of pregnancy when the oral glucose tolerance test was performed. Selenium concentration was determined by atomic absorption spectrometry after hydride generation. HsCRP was measured by immunturbidimetry. HC had significantly higher serum selenium concentrations than GD and CP women (HC = 77.4 +/- 14.82, GD = 51.7 +/- 11.62, and CP = 40.5 +/- 8.03 microg/l, respectively). HsCRP values of both GD and nondiabetic pregnant women were significantly higher compared to controls. Significant negative correlations were found between serum selenium and total cholesterol, low-density lipoprotein cholesterol, and hsCRP values indicating that low selenium levels are associated with increased lipid peroxidation. Serum selenium concentrations of Hungarian pregnant women are low compared to internationally published data.

Abstract
BACKGROUND Rituximab has been shown to improve response rates and progression free survival when added to chemotherapy in patients with indolent and mantle cell lymphoma. However, the impact of R on overall survival (OS) when given in combination with chemotherapy (R-chemo) has remained unclear so far. OBJECTIVES We thus performed a comprehensive systematic review in this group of patients to compare R-chemo with chemotherapy alone with respect to OS. Other endpoints were overall response rate (ORR), toxicity and disease control as assessed by measures such as time to treatment failure (TTF), event free-survival (EFS), progression free-survival (PFS) and time to progression (TTP). SEARCH STRATEGY We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE, EMBASE and conference proceeding from 1990 to 2005. SELECTION CRITERIA Only randomised controlled trials (RCT) comparing R-chemo with chemotherapy alone in patients with newly diagnosed or relapsed indolent lymphoma and mantle cell lymphoma (MCL) were included. DATA COLLECTION AND ANALYSIS Two review authors extracted data and assessed the study quality. Number needed to treat (NNT) were calculated to facilitate interpretation. MAIN RESULTS Seven randomised controlled trials involving 1943 patients with follicular lymphoma, mantle cell lymphoma, or other indolent lymphomas were included in the meta-analysis. Five studies were published as full-text articles, and two were in abstract form. Patients treated with R-chemo had better overall survival (hazard ratio [HR] for mortality 0.65; 95% confidence interval (CI) 0.54 to 0.78), overall response (relative risk of tumour response 1.21; 95% CI 1.16 to 1.27), and disease control (HR of disease event 0.62; 95% CI 0.55 to 0.71) than patients treated with chemotherapy alone. R-chemo improved overall survival in patients with follicular lymphoma (HR for mortality 0.63; 95% CI 0.51 to 0.79) and in patients with mantle cell lymphoma (HR for mortality 0.60; 95% CI 0.37 to 0.98). However, in the latter case, there was heterogeneity among the trials (P 0.07), making the survival benefit less reliable. AUTHORS' CONCLUSIONS The systematic review demonstrated improved OS for patients with indolent lymphoma, particularly in the subgroups of follicular and in mantle cell lymphoma when treated with R-chemo compared to chemotherapy alone.

Abstract
PURPOSE This randomized phase III study compared bendamustine and prednisone (BP) to standard melphalan and prednisone (MP) treatment in previously untreated patients with multiple Myeloma (MM). PATIENTS AND METHODS To be included, patients had to have histologically and cytologically proven stage II with progressive diseases or stage III MM. They were randomly assigned to receive BP (n=68) or MP (n=63). The primary endpoint was the time to treatment failure (TTF). Secondary endpoints included survival, remission rate, toxicity and quality of life. RESULTS The overall response rate was 75% in the BP and 70% in the MP group. A significantly higher number of patients treated with BP achieved a complete remission than did patients receiving MP (32 vs. 13%; P=0.007), and the maximum response was achieved more rapidly in patients treated with BP compared to those receiving MP (6.8 vs. 8.7 cycles; P<0.02). TTF and remission duration were significantly longer in the BP group. Patients receiving BP had higher QoL scores and reported pain less frequently than patients receiving MP. CONCLUSION BP is superior to MP with respect to complete remission rate, TTF, cycles needed to achieve maximum remission and quality of life and should be considered the new standard in first-line treatment of MM patients not eligible for transplantation.

Abstract
During 7 consecutive days, blood and several tissues were collected during daytime working hours only, three times per day at 4-h intervals from inbred Wistar rats, which had been previously standardized for 1 month in two rooms on a regimen of 12 h of light (L) alternating with 12 h of darkness (LD12:12). In one room, lights were on from 09:00 to 21:00 and in the other room, lights were on from 21:00 to 09:00 (DL12:12; reversed lighting regimen). This setup provides a convenient design to study circadian and extracircadian variations over long (e.g., 7-day) spans. Prior checking of certain circadian rhythms in animals reared in the room on reversed lighting (DL) as compared with animals in the usual (LD) regimen provided evidence that the 180 degrees phase-shift had occurred. These measurements were limited to the circadian (and not extended to infradian) variation. As marker rhythm, the core temperature of a subsample of rats was measured every 4 h around the clock (by night as well as by day) before the start of the 7-day sampling. An antiphase of the circadian rhythm in core temperature was thus demonstrated between rats in the LD vs. DL rooms. A sex difference in core temperature was also found in each room. A reversed rhythm in animals kept in DL and an antiphase between rats kept in DL vs. LD was again shown for the circulating corticosterone rhythm documented in subsamples of 8 animals of each sex sampled around the clock during the first approximately 1.5 day of the 7-day sampling. The findings were in keeping with the proposition that sampling rats at three timepoints 4 h apart during daytime from two rooms on opposite lighting regimens allows the assessment of circadian changes, the daytime samples from animals kept on the reversed lighting regimen accounting for the samples that would have to be obtained by night from animals kept in the room with the usual lighting regimen. During the 7-day-long follow-up, circadian and extracircadian spectral components were mapped for serum corticosterone, taking into account the large day-to-day variability. A third check on the synchronization of the animals to their respective lighting regimen was a comparison (and a good agreement) between studies carried out earlier on the same variables and the circadian results obtained on core temperature and serum corticosterone in this study as a whole. The present study happened to start on the day of the second extremum of a moderate double magnetic storm. The study of any associations of corticosterone with the storm is beyond our scope herein, as are the results on circulating prolactin, characterized by a greater variability and a larger sex difference than corticosterone. Sex differences and extracircadian aspects of prolactin and endothelin determined in the same samples are reported elsewhere, as are results on melatonin. Prior studies on melatonin were confirmed insofar as a circadian profile is concerned by sampling on two antiphasic lighting regimens, as also reported elsewhere. Accordingly, a circadian map for the rat will eventually be extended by the result of this study and aligned with other maps with the qualification of the unassessed contribution in this study of a magnetic storm.

Abstract
A multi-center four-hourly sampling of many tissues for 7 days (00:00 on April 5-20:00 to April 11, 2004), on rats standardized for 1 month in two rooms on antiphasic lighting regimens happened to start on the day after the second extremum of a moderate double magnetic storm gauged by the planetary geomagnetic Kp index (which at each extremum reached 6.3 international [arbitrary] units) and by an equatorial index Dst falling to -112 and -81 nT, respectively, the latter on the first day of the sampling. Neuroendocrine chronomes (specifically circadian time structures) differed during magnetically affected and quiet days. The circadian melatonin rhythm had a lower MESOR and lower circadian amplitude and tended to advance in acrophase, while the MESOR and amplitude of the hypothalamic circadian melatonin rhythm were higher during the days with the storm. The circadian parameters of circulating corticosterone were more labile during the days including the storm than during the last three quiet days. Feedsidewards within the pineal-hypothalamic-adrenocortical network constitute a mechanism underlying physiological and probably also pathological associations of the brain and heart with magnetic storms. Investigators in many fields can gain from at least recording calendar dates in any publication so that freely available information on geomagnetic, solar and other physical environmental activity can be looked up. In planning studies and before starting, one may gain from consulting forecasts and the highly reliable nowcasts, respectively.

Abstract
Antibodies directed to cyclic citrullinated peptides (anti-CCP) are highly
specific for rheumatoid arthritis (RA) and can easily be detected in sera by using
commercially available immunoassays. The second version of the anti-CCP test
(anti-CCP2) demonstrated high specificity (89-98%) and good sensitivity (41-88%)
for RA. Commercially available ELISA methods from three different companies are
on the market. All three CCP2 assays show similar results as all CCP2 assays
use the same antigen-coated plates. This study was an evaluation of a new
automated method for the determination of anti-CCP2 in a routine laboratory
setting. Five hundred and fourty three serum samples were tested for anti-CCP2
within normal routine diagnostic using a commercially available ELISA and retested
with a prelaunch version of a new and fully-automated method (EliA™). The results
were comparable. The new automated assay is easy to
use and demonstrated a diagnostic sensitivity of 80% and specificity of 97%.

Abstract
UNLABELLED The effect of supplementary Vitamin E on the vitamin content of lipoproteins in young men and women. Inappropriate vitamin and trace element supplementation may facilitate the development of atherosclerosis. It is known that Vitamin E protects lipids from oxidative stress, while clinical signs of atherosclerosis appear later in women compared to men. AIMS (1) The increase of vitamin E in plasma and plasma lipoproteins after 4 weeks of supplementation vitamin E was investigated, (2) furthermore it was tested whether a proportion shift occurs in alpha-tocopherol content of lipoproteins, (3) and checked for gender-related differences in plasma and plasma lipoprotein vitamin E levels before, during and after treatment, (4) plasma CRP levels as a marker of lipid peroxidation were also followed. METHODS 5-5 young healthy men and women took part in the study, receiving 700 IU/day Vitamin E for one month. Each subject was studied before and at the end of treatment, and also one month after treatment. HDL and LDL-VLDL containing lipoproteins were separated. Vitamin E and hsCRP levels were measured (by HPLC and an immunoturbidimetric method, respectively). RESULTS Vitamin E treatment induced in both genders an approximately threefold increase in vitamin E concentration in HDL-cholesterol (8.1 +/- 1.7 micromol/l vs. 22.5 +/- 7.5 micromol/l, p < 0.001), and a twofold increase in LDL-VLDL-cholesterol (22.0 +/- 3.7 micromol/l vs. 49.0 +/- 9.0 micromol/l, p < 0.001). Plasma and HDL vitamin E levels were higher in women than in men at the onset of treatment (6.8 +/- 0.96 micromol/l vs. 9.5 +/- 1.10 micromol/l), but during the treatment these gender-related differences disappeared. When plasma vitamin E concentration were considered 100% and the changes of the vitamin E concentrations of lipoproteins were calculated, it was found that supplementation with vitamin E in men increased the vitamin E concentration of LDL-VLDL cholesterol to a higher extent compared to women (LDL-VLDL % in men: 59.8 +/- 7.43%, in women: 49.3 +/- 7.41%, p < 0.05). All the observed changes regressed one month after cessation of supplementation. The level of hsCRP decreased during vitamin E treatment (1.07 +/- 0.9 mg/l vs. 0.2 +/- 0.14 mg/l, p < 0.001), and remained suppressed after the cessation of treatment (0.37 +/- 0.4, p < 0.01). CONCLUSIONS These results support the hypothesis that women at young age are better protected against lipid-peroxidation as compared to men because of higher HDL vitamin E concentrations. Vitamin E supplementation in men eliminates this concentration difference between genders, and also increases LDL-VLDL vitamin E. In both genders high concentration of vitamin E in lipoproteins was associated with low hsCRP concentration.

Abstract
PURPOSE The purpose of this study was to compare the efficacy and toxicity of bendamustine, vincristine + prednisone (BOP) with a standard regimen of cyclophosphamide, vincristine + prednisone (COP) in patients with previously untreated advanced indolent non-Hodgkin's lymphoma (NHL) and mantle cell lymphoma. METHODS A total of 164 patients with follicular lymphoma (grade 1/2), mantle cell lymphoma or lymphoplasmacytic lymphoma (immunocytoma) was randomised to treatment with vincristine 2 mg (day 1) and prednisone 100 mg/m2 (days 1-5) + bendamustine 60 mg/m2 (days 1-5) or + cyclophosphamide 400 mg/m2 (days 1-5) for a total of eight 21-day cycles. RESULTS The rate of complete remission was 22% with BOP and 20% with COP. The projected 5-year survival rate was 61% with BOP and 46% with COP. The BOP-associated 5-year survival advantage almost reached significance in the subgroup of patients who responded to therapy (74% vs. 56%; P = 0.05), and did reach significance in responders who did not receive interferon maintenance therapy (70% vs. 47%; P = 0.03). Toxicity was acceptable in both treatment groups, although alopecia and leucopenia were more severe with COP. CONCLUSIONS Bendamustine can efficaciously and safely replace cyclophosphamide, as used in standard COP therapy, for the treatment of patients with indolent NHL and mantle cell lymphoma. Long-term survival data suggest a clinically significant benefit for patients treated with BOP.

Abstract
BACKGROUND Aviscumine is an Escherichia coli-derived recombinant type II ribosome-inactivating protein with potent antitumor activity in vitro and in vivo. It is the recombinant counterpart of natural mistletoe lectin-I. The current study was performed to determine the safety profile, dose-limiting toxicity (DLT) and maximum tolerated dose (MTD) of the intravenous (i.v.) administration of aviscumine in cancer patients. Translational research included the evaluation of pharmacokinetics and monitoring of plasma cytokine and anti-aviscumine antibody induction after administration of the drug. PATIENTS AND METHODS Aviscumine was given twice weekly as a 1 h central i.v. infusion in patients with advanced, refractory progressive, solid malignant tumors who had not been previously exposed to natural mistletoe preparations. They had histologically or cytologically verified disease, were > or =18 years old, had an Eastern Cooperative Oncology Group performance status < or =2 and adequate bone marrow, liver and renal function. DLT was defined as any non-hematological grade 3-4 toxicity (National Cancer Institute Common Toxicity Criteria version 2.0), neutrophil count <500/microl for > or =7 days, febrile neutropenia or thrombocytopenia grade 4. The MTD was defined as the dose at which >20% of patients experienced DLT during the first treatment cycle. The Continual Reassessment Method was used to determine the number of patients required per dose level. RESULTS Forty-one fully eligible patients (19 male, 22 female) with a median age of 56 years (range 37-74) were enrolled. Colorectal, ovarian, renal cell and breast cancer were the most common tumor types. Dose levels of aviscumine ranged from 10 to 6400 ng/kg. The median number of cycles was two (range one to eight). Common clinical toxicities in cycle 1 were fatigue, fever, nausea, vomiting and allergic reactions. Fatigue grade 3 was dose limiting in one of six patients at 4000 ng/kg and reversible grade 3 liver toxicity (elevation in alkaline phosphatase, transaminases and/or gamma-glutamyltransferase) occurred in one of 10 patients at 4800 ng/kg and in two of five patients at 6400 ng/kg. The best response (RECIST criteria) was stable disease in 11 patients, lasting for two to eight cycles. The pharmacokinetic evaluation revealed a short alpha half-life of 13 min and linear kinetics on dose levels > or =1600 ng/kg. Aviscumine stimulated the immune system with a release of cytokines such as interleukin (IL)-1beta, IL-6 and interferon-gamma, and induced immunoglobulin (Ig) G- and/or IgM-anti-aviscumine antibodies of uncertain clinical relevance. CONCLUSIONS The recommended dose for further clinical trials is 5600 ng/kg twice weekly. Based on the short half-life of the recombinant protein observed in this trial, the exploration of prolonged infusion schedules of aviscumine is warranted.

Abstract
The assessment of the postprandial state in diabetes mellitus has gained importance due to postprandial hyperglycemia being considered as an independent risk factor for cardiovascular disease. Hyperglycemia may contribute to vascular dysfunction through the alteration of the nitric oxide/cyclic guanosine monophosphate (NO/cGMP) pathway. The authors assessed the NO/cGMP pathway in the fasting and postprandial state in 20 type 1 diabetic patients (age: 34.1 +/- 2.6 years, body mass index (BMI): 24.1 +/- 1.3 kg/m (2), duration of diabetes: 16 +/- 2.2 years, HbA (1C): 8.3 +/- 0.4 %, [x +/- SEM], 10 without, 10 with late complications) and 20 matched control subjects (age: 39.7 +/- 1.9 years, BMI: 25.3 +/- 1.1 kg/m (2)). In the fasting state NO end product (nitrite/nitrate) levels did not differ between the diabetic and control group, cGMP levels were found to be significantly lower in the diabetic group (2.5 +/- 0.2 vs. 4.6 +/- 0.6 nmol/l, p = 0.01). A higher level of lipid peroxidation end products (TBARS) was found in diabetic subjects (6.7 +/- 0.4 vs. 5.0 +/- 0.3 micro mol/l, p = 0.004). The diabetic subgroup without late complications had significantly higher nitrite/nitrate levels compared to the patients with complications (57.8 +/- 6.6 vs. 30.4 +/- 4.3 micro mol/l, p = 0.006), their TBARS and cGMP levels were similar. The control subjects responded to the test meal with an increase in the cGMP levels (4.6 +/- 0.6 to 5.5 +/- 0.6 nmol/l, p = 0.02), while in the diabetic group no change was detected. Postprandial nitrite/nitrate levels decreased in both groups, they were significantly lower in the diabetic group. There was no difference between postprandial nitrite/nitrate, cGMP, or glucose levels in the diabetic subgroups. Postprandial glucose levels showed a significant negative correlation with cGMP levels in the diabetic group (r = - 0.50, p = 0.02). The results suggest that in subjects with type 1 diabetes mellitus NO might have an impaired ability to induce cGMP production in the fasting state prior to the development of late specific complications or microalbuminuria under hyperglycemic conditions. Postprandial hyperglycemia is suggested to interfere with endothelial NO action, as shown by the decreased nitrite/nitrate and unchanged cGMP plasma levels in the diabetic group. The impairment of the NO/cGMP pathway both in the fasting and postprandial state that was shown in patients without diabetic complications may be an early sign of hyperglycemia induced vascular damage in type 1 diabetes mellitus.

Abstract
BACKGROUND Involvement of the metacarpophalangeal (MP) joints is one of the major problems in patients with rheumatoid arthritis (RA). Although several data about the cumulative influence of steroid intake on bone are available, the course of demineralisation in RA has not been described by quantitative methods until now. PATIENTS AND METHODS Computed tomography (CT) sections of 96 MP joints in 12 RA patients and of 32 MP joints in four age-matched healthy controls were investigated. Patients were classified according to Steinbrocker. Densitometric evaluation of subchondral bone density was performed by CT osteoabsorptiometry (CT-OAM). Quantitative CT-OAM was used to evaluate mineralisation of the articular surfaces in MP joints. RESULTS In the distal articular surface of MP joints, the number of density maxima was reduced from 3 to 2.1+/-0.3, 1.9+/-0.5 and 1.3+/-0.3 in RA patients with early, mild to moderate, and severe disease, respectively. Means of calcium concentrations were 633.4+/-35. 3 mg Ca2+/mL, 518.9+/-56.2 mg Ca2+/mL, 497.7+/-23.8 mg Ca2+/mL and 455.1+/-28.6 mg Ca2+/mL for controls and RA patients with early, mild to moderate, and severe RA, respectively. Mineralisation of the distal articular surface was significantly reduced in all groups of RA patients [probability (p) = 0.005]. Regarding the number of density maxima, no differences were detected in the proximal articular surface of normal and RA fingers. However, mineralisation of the proximal articular surface was significantly reduced in all groups of RA patients (p = 0.004). Means of calcium concentrations of the proximal articular surface were 494.1+/-48.5 mg Ca2+/mL, 413.0+/-16.2 mg Ca2+/mL, 406.0+/-51.4 mg Ca2+/mL, 390,4+/-41.1 mg Ca2+/mL for controls and RA patients with early, mild to moderate, and severe RA, respectively. CONCLUSION Patients with early and untreated RA show loss of mineralisation and altered morphology of the MP joints of the hand, even before corticosteroid therapy. CT-OAM provides evidence for an early alteration of functional anatomy in MP joints.

Abstract
Detection of antiphospholipid (aPL) antibodies in bronchoalveolar lavage fluid (BALF) of patient with acute respiratory distress syndrome (ARDS) suggests involvement of autoimmune mechanisms in the pathogenesis of ARDS. We investigated whether aPL antibodies could be detected in the serum as well as BALF of patients with acute lung injury (ALI) and ARDS. IgG anticardiolipin, IgG anti-beta2-glycoprotein I, IgG antiphosphatidic acid and IgG antiphosphatidylserine antibodies were detected by ELISA in low titers within the normal range in the BALF and serum of nine patients with ALI and 17 patients with ARDS. However, one out of 27 patients investigated had high levels of aPL antibodies in both BALF and serum. This patient suffered from severe ARDS due to sepsis. The high aPL antibody levels in serum possibly triggered by sepsis were associated with high aPL antibody levels in BALF, which can be explained by high capillary-alveolar permeability. Computed tomography scan revealed widespread infarctions in brain, spleen and kidneys, and pulmonary thromboembolism, suggesting the diagnosis of catastrophic antiphospholipid syndrome.
