Abstract
The frequency of nocturnal hypoglycaemia, i.e. blood glucose concentration (BG) less than 3.0 mmol/l, was evaluated in consecutively selected insulin-dependent patients on multiple insulin injections (MII), n = 23, or continuous subcutaneous insulin infusions (CSII), n = 25. Blood was sampled hourly from 23.00 to 07.00. Seven patients (30%) on MII had at least one BG less than 3.0 mmol/l during the night. Eleven patients (44%) on CSII had hypoglycaemia (NS). The total number of BGs less than 3.0 mmol/l was higher on CSII, 42 of 225, versus 16 of 207 on MII (p less than 0.025). The duration of hypoglycaemia was 2 hours (range 1-6) on MII and 4 hours (range 1-7) on CSII with a maximal prevalence at 4 hours and between 5 and 7 hours, respectively (p = less than 0.05). The frequency of nocturnal hypoglycaemia is high in patients on intensified insulin regimens. Nocturnal hypoglycaemia occurs later in the night and is of longer duration on CSII than on MII. HbA1c, BG before bedtime and in the morning might be useful in the evaluation of nocturnal hypoglycaemia.

Abstract
The contribution of decreased hepatic insulin extraction to the relative hyperinsulinemia after oral glucose load as compared to intravenous glucose load was studied in 6 normal weight male volunteers by means of an analysis of the relationship between peripheral venous concentrations of insulin and C-peptide following similar glycemic stimuli after oral and intravenous glucose administration. The incremental areas under the insulin and C-peptide curves were higher during oral as compared to intravenous glucose administration, 436 (251--762) per cent and 267 (124-378) per cent respectively (mean and range). The ratio between corresponding incremental areas of insulin and C-peptide were 53 (17--103 per cent higher during oral glucose load. These findings suggest that the augmented peripheral insulin levels after oral glucose administration are caused by a combination of increased beta cell secretion and decreased hepatic insulin extraction.

Abstract
Alterations in circulating iodothyronines were studied in 15 juvenile type diabetic patients during the development of metabolic derangement after withdrawal of insulin. By means of measurements of circulating C peptide, one group of patients with and one without residual beta-cell function had been selected. In both groups there was a gradual decrease in serum T3 during the 12-hour period studied after withdrawal of insulin, while an increase in serum rT3 was observed after 4-6 hours. The alterations in serum T3 and the metabolic derangement were significantly more pronounced in patients without than with residual beta-cell function.

Abstract
7538 Background: The clinical course of peripheral T-cell lymphomas (PTCL) is unfavourable. Treatment protocols developed for aggressive B-NHL are employed, with significantly worse outcomes. The MoAb alemtuzumab (CAM) has shown promising activity in T-NHL, although its use may be complicated by severe infections. Methods: In 2003, the DSHNHL group initiated a prospective multicenter phase II trial for previously untreated PTCL. Six cycles of either CHOEP-14 (< 60 y) or CHOP-14 (> 60 y) with G-CSF support are followed by a short consolidation course with CAM, when either a CR or a good PR has been achieved. Inclusion criteria: PTCL-NOS, AILD, intestinal T-NHL, anaplastic large cell T-NHL (ALK negative); age 18–70 y; all IPIs; ECOG PS 0–3. The primary endpoint is feasibility, measured by occurrence SAE and protocol adherence. Secondary endpoints are remission rate, TTF, OS, DFS, tumor control and TRM. CAM is given at a total dose of 133 mg over 4 weeks. Prophylaxis against PCP and herpes infections is mandatory during CAM therapy and is continued until CD 4 cells are > 200/μl. CMV-positive patients are monitored weekly. Results: 35 (of the planned 37) pts have been enrolled, 31 are evaluable. 5/31 pts are still undergoing chemotherapy. 7/31 pts had progressive disease or NC under/after chemotherapy and did not receive CAM. 18 of the 19 pts who achieved a CR/PR (15/4) received CAM. 12 of the CAM pts are in continuous CR, 7 had progressive disease or relapsed. There was no treatment-related death. Of 7 registered SAEs, 3 were related to chemotherapy, 4 to CAM (1 fungal pneumonia, 2 CMV pneumonias, 1 bacterial sepsis after dental procedure). Other CAM side effects were: Herpes Zoster (1), CMV-reactivation (1), grade III-IV neutropenias (2). All pts recovered with appropriate treatment. Conclusion: Preliminary analysis demonstrates that the combination of CHO/E/P-14 followed by a short course of CAM consolidation therapy is feasible without TRM. The adverse effects related to infections can be severe but manageable upon careful monitoring and close follow-up. The phase II trial will close in 4/2006, to be followed by a randomized phase III trial of A-CHOP-14 vs CHOP-14. No significant financial relationships to disclose.

Abstract
Interactions between neoplastic and stromal cells contribute to tumor progression. Wnt genes, involved in cell migration and often deregulated in cancers, are attractive candidates to regulate these effects. We have recently shown that coculture of breast cancer cells with macrophages enhances invasiveness via matrix metalloproteases and TNF-alpha. Here we demonstrate that coculture of MCF-7 cells and macrophages leads to up-regulation of Wnt 5a in the latter. This was accompanied by activation of AP-1/c-Jun in MCF-7. Recombinant Wnt 5a mimicked the coculture effect. Wnt 5a was also detectable in tumor-associated macrophages in primary breast cancers. Experiments with agonists and antagonists of Wnt signaling revealed that a functional canonical pathway in the tumor cells was a necessary prerequisite; however, noncanonical signaling via Wnt 5a and the Jun-N-terminal kinase pathway was critical for invasiveness. It was also responsible for induction of matrix metalloprotease-7, known to release TNF-alpha. All these effects could be antagonized by dickkopf-1. Our results indicate that Wnt 5a is essential for macrophage-induced invasiveness, because it regulates tumor cell migration as well as proteolytic activity of the macrophages. The function of Wnt 5a as either a suppressor or promoter of malignant progression seems to be modulated by intercellular interactions. Wnt 5a detection in tumor-associated macrophages in breast cancer biopsies supports the assumption that similar events play a role in vivo.

Abstract
The diagnostic work-up of suspected food allergy includes the skin prick test (SPT), the measurement of food specific immunoglobulin E (IgE) antibodies using serologic assays, and more recently the atopy patch test (APT). For specific serum IgE and the SPT, decision points have been established for some foods allowing prediction of clinical relevance in selected cases. The APT may be helpful, especially when considered in combination with defined levels of specific IgE. Controlled oral food challenges still remain the gold standard in the diagnostic work-up of children with suspected food allergy. Most food allergic children will lose their allergy over time. As there is no laboratory parameter, which can accurately predict when clinical tolerance has been developed, controlled oral food challenges are the measure of choice. In this article, the current knowledge of predictors for the outcome of oral food challenges is reviewed and proposals for the daily practical work-up in the case of suspected food related clinical symptoms are presented.

Abstract
Relaxin (RLX) is known to induce remodeling of benign stromal tissues through upregulation of matrix metalloproteases (MMPs). Recently, we could show that RLX also induces MMPs in breast cancer cells and enhances in vitro invasiveness. To investigate its potential role for progression of breast cancer in vivo, RLX serum concentrations were determined in 160 breast cancer patients during post-surgical follow-up. RLX concentrations in cancer patients were significantly higher than in a control population of healthy blood donors and patients with various other diseases (0.47 versus 0.29 ng/ml, p < 0.0001). There was a significant difference between patients with metastases (0.62 ng/ml) and those without (0.38 ng/ml, p < 0.0001). Overall survival was shorter in RLX-positive ( > 0.4 ng/ml) than in RLX-negative patients (p = 0.016). Cox regression analysis showed that RLX was not an independent variable, in contrast to metastatic disease and primary lymph node involvement. Taken together, the detection of elevated RLX concentrations especially in patients with metastases supports the assumption that there is a role for RLX in tissue remodeling during breast cancer progression.

Abstract
BACKGROUND The authors evaluate the prevalence of Helicobacter pylori resistance in 117 children and demonstrate the changes over a 4-year period. METHODS In 117 children and adolescents, H. pylori-positive gastritis was revealed by diagnostic upper endoscopy. Biopsies from the antrum and body of the stomach were tested by histology, urease test, and culture. H. pylori was isolated using standard culture techniques, and susceptibility to amoxicillin, clarithromycin, and metronidazole was tested using the E-test (AB-Biodisk, Sweden). RESULTS Endoscopy revealed gastric ulcers in 2 of 117 subjects, duodenal ulcers in 6 of 117, and erosive gastritis or duodenitis in 23 of 117. Almost all patients showed antral nodularity. Histology always showed chronic gastritis with different degrees of activity. During the 4-year study period, the authors noticed an increase of primary clarithromycin-resistant H. pylori strains, from 14.3% to 27.6% (mean, 20.3%). Metronidazole resistance varied between 5% and 25%. No resistance to amoxicillin was found. CONCLUSION Eradication of H. pylori should take place only after testing of susceptibility. The general use of clarithromycin in children should be restricted to better-defined indications. Resistance to clarithromycin of H. pylori may also become a future problem for the treatment of adults.

Abstract
Plasma concentrations of procalcitonin (PCT) have been shown to be elevated in bacterial and fungal infections. In contrast to C-reactive protein (CRP), PCT is not elevated in inflammations of noninfectious origin. Febrile inflammatory conditions are frequent in patients with hemato-oncological diseases. A reliable marker to discriminate infectious inflammations from drug-related and tumor-associated fever is still lacking. To evaluate the impact of PCT in this setting, PCT and CRP were prospectively measured in 95 febrile hemato-oncological patients. Infections could be identified in 40 of 95 patients: 38 of 95 had fever of unknown origin (FUO), 9 patients were suspected to suffer from drug-related fever, and 8 patients from tumor-associated fever. In the noninfection group (drug-related and tumor-associated fever), PCT levels were significantly lower than in patients with infections (P<0.001) or FUO (P<0.001). Differences were still highly significant comparing patients with suspected drug-related or tumor-associated fever alone with the infection or the FUO cohort. All eight patients with tumor-associated fever as well as eight of the nine patients with drug-related fever had PCT levels within the normal range (<0.5 micro g/l). CRP values only partially allowed discrimination between the various subgroups. Differences were significant between patients with drug-related fever and the infection (P=0.001) or FUO group (P=0.004). However, as CRP levels were far above the normal range also in the patients with drug-related fever, the significance of individual values was rather limited. In conclusion, PCT may provide useful additional information to assess the clinical significance of febrile conditions. PCT may facilitate the decision on when to initiate antimicrobial or cytotoxic therapy.

Abstract
Until recently, relaxin (RLX) has been known predominantly for its effects on the reproductive system, where it induces remodelling of the extracellular matrix and up-regulation of matrix metalloproteases (MMPs). In solid cancers, tissue remodelling and MMP activation are essential for invasion and metastasis. We therefore investigated the effect of RLX on invasiveness and MMP expression of human breast cancer cell lines. Upon incubation with porcine RLX, the invasiveness of SK-BR3 cells was significantly increased. Similar effects could be achieved in MCF-7 cells, especially when RLX was combined with epidermal growth factor. Enhanced invasiveness was accompanied by up-regulation of MMP production and could be almost completely blocked by the MMP inhibitor FN 439. Zymography revealed increased secretion of MMP-2, -7 and -9, associated with up-regulated mRNA concentrations of MMP-2, -9, -13 and -14. mRNA expression levels of MMP-1, -3, -7, -8, -10, -11, -12 and of tissue inhibitors of metalloproteases-1, -2, -3 and -4 were either very low or not detectably influenced by RLX. Taken together, RLX enhances in-vitro invasiveness of breast cancer cell lines by induction of MMP expression. It remains to be clarified whether RLX might play a similar role in vivo and promote tumour progression.

Abstract
Altered expression of matrix metalloproteases (MMPs) and their inhibitors, the tissue inhibitors of matrix metalloproteases (TIMPs), has been demonstrated in various tumour tissues. mRNA expression patterns of MMP-1, MMP-2, MMP-3, MMP-9, MMP-11, MMP-12, MMP-14 and TIMP-1, TIMP-2, TIMP-3 and TIMP-4 were evaluated by quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) in 30 renal cell carcinomas (RCC), as well as in the surrounding tissues. Expression of the MMPs was significantly stronger in the carcinomas than in non-malignant tissues. High levels were demonstrated particularly in clear cell RCCs (CC-RCC). Except for MMP-1, MMP expression in the papillary RCCs (P-RCC) was, for most MMPs, significantly lower. Expression of the TIMPs in malignant cells of both subtypes was weak, with the exception of TIMP-4 which was strongly expressed in the P-RCCs and downregulated in the CC-RCCs. The latter was correlated with chromosomal loss of 3p, harbouring the TIMP-4 gene locus. In conclusion, deregulated expression of the MMPs and TIMPs in RCCs differs according to histology, grade, size and cytogenetic characteristics, suggesting that MMP and TIMP expression patterns play an important role for the typical histomorphological features of RCC subtypes and their respective biological behaviour.

Abstract
Cow's milk allergy/intolerance is treated by complete avoidance of cow's milk proteins. Because cow's milk is an important food for infants, its avoidance may lead to an increased risk of growth impairment. Whilst there is evidence for the beneficial effects of extensively hydrolyzed cow's milk formulate (eHF) in infants with cow's milk allergy/intolerance, little is known about the effects of amino-acid-based formulae (AA) in such infants. We therefore performed a prospective, controlled, multi-center trial to study the efficacy of AA in comparison with eHF, on the growth and clinical symptoms of 73 infants (median age 5.7 months) with cow's milk allergy/intolerance and atopic dermatitis. Cow's milk allergy/intolerance was proven in all infants by double-blind, placebo-controlled food-challenge. We observed a significant improvement in the SCORAD index in both groups, from a mean of 24.6, at entry, to a mean of 10.7 (p < 0.0001) after 6 months. In the AA group there was a significant increase in the length standard deviation score (p < 0.04), whilst there was no difference in the eHF group. The weight-for-length values were stable in both groups. The energy intake during the study was similar in both groups. Both an AA and eHF resulted in a significant clinical improvement in infants with an early onset of symptoms of cow's milk allergy/intolerance. Feeding an AA resulted in improved growth compared with feeding eHF, despite similar dietary intakes, and may therefore be considered as a beneficial alternative in infants with severe cow's milk allergy intolerance.
