Evaluation of aggregating brain cell cultures for the detection of acute organ-specific toxicity.

As part of the ACuteTox project aimed at the development of non-animal testing strategies for predicting human acute oral toxicity, aggregating brain cell cultures (AGGR) were examined for their capability to detect organ-specific toxicity. Previous multicenter evaluations of in vitro cytotoxicity showed that some 20% of the tested chemicals exhibited significantly lower in vitro toxicity as expected from in vivo toxicity data. This was supposed to be due to toxicity at supracellular (organ or system) levels. To examine the capability of AGGR to alert for potential organ-specific toxicants, concentration-response studies were carried out in AGGR for 86 chemicals, taking as endpoints the mRNA expression levels of four selected genes. The lowest observed effect concentration (LOEC) determined for each chemical was compared with the IC20 reported for the 3T3/NRU cytotoxicity assay. A LOEC lower than IC20 by at least a factor of 5 was taken to alert for organ-specific toxicity. The results showed that the frequency of alerts increased with the level of toxicity observed in AGGR. Among the chemicals identified as alert were many compounds known for their organ-specific toxicity. These findings suggest that AGGR are suitable for the detection of organ-specific toxicity and that they could, in conjunction with the 3T3/NRU cytotoxicity assay, improve the predictive capacity of in vitro toxicity testing.

Cytogenetic characterisation of childhood acute lymphoblastic leukemia in Nicaragua

BACKGROUND: Within the frame of a twinning programme with Nicaragua, The La Mascota project, we evaluated in our study the contribution of cytogenetic characterization of acute lymphoblastic leukemia (ALL) as prognostic factor compared to clinical, morphological, and immunohistochemical parameters. METHODS: All patients with ALL treated at the only cancer pediatric hospital in Nicaragua during 2006 were studied prospectively. Diagnostic immunophenotyping was performed locally and bone marrow or blood samples were sent to the cytogenetic laboratory of Zurich for fluorescence in situ hybridization (FISH) analysis and G-banding. RESULTS: Sixty-six patients with ALL were evaluated. Their mean age at diagnosis was 7.3 years, 31.8% were >or=10 years. Thirty-four patients (51.5%) presented with hyperleucocytosis >or=50 x 10(9)/L, 45 (68.2%) had hepatosplenomegaly. Immunophenotypically 63/66 patients (95%) had a B-precursor, 2 (3%) a T- and 1 (1.5%) a B-mature ALL. FISH analysis demonstrated a TEL/AML1 fusion in 9/66 (14%), BCR/ABL fusion in 1 (1.5%), MLL rearrangement in 2 (3.1%), iAMP21 in 2 (3.1%), MYC rearrangement in 1 (1.5%), and high-hyperdiploidy in 16 (24%). All patients but two with TEL/AML1 fusion and high-hyperdiploidy were clinically and hematologically in the standard risk group whereas those with poor cytogenetic factors had clinical high-risk features and were treated intensively. CONCLUSIONS: Compared to Europe, the ALL population in Nicaragua is older, has a higher proportion of poor prognostic clinical and hematological features and receives more intensive treatment, while patients with TEL/AML1 translocations and high-hyperdiploidy are clinically in the standard risk group. Cytogenetics did not contribute as an additional prognostic factor in this setting.

A new automated method versus continuous positive airway pressure method for measuring pressure-volume curves in patients with acute lung injury

Objective: To compare pressure–volume (P–V) curves obtained with the Galileo ventilator with those obtained with the CPAP method in patients with ALI or ARDS receiving mechanical ventilation. P–V curves were fitted to a sigmoidal equation with a mean R2 of 0.994 ± 0.003. Lower (LIP) and upper inflection (UIP), and deflation maximum curvature (PMC) points calculated from the fitted variables showed a good correlation between methods with high intraclass correlation coefficients. Bias and limits of agreement for LIP, UIP and PMC obtained with the two methods in the same patient were clinically acceptable.

B-cell infiltration and frequency of cytokine producing cells differ between localized and disseminated human cutaneous leishmaniases

Biopsies from human localized cutaneous lesions (LCL n = 7) or disseminated lesions (DL n = 8) cases were characterized according to cellular infiltration,frequency of cytokine (IFN-g, TNF-alpha) or iNOS enzyme producing cells. LCL, the most usual form of the disease with usually one or two lesions, exhibits extensive tissue damage. DL is a rare form with widespread lesions throughout the body; exhibiting poor parasite containment but less tissue damage. We demonstrated that LCL lesions exhibit higher frequency of B lymphocytes and a higher intensity of IFN-gamma expression. In both forms of the disease CD8+ were found in higher frequency than CD4+ T cells. Frequency of TNF-alpha and iNOS producing cells, as well as the frequency of CD68+ macrophages, did not differ between LCL and DL. Our findings reinforce the link between an efficient control of parasite and tissue damage, implicating higher frequency of IFN-gamma producing cells, as well as its possible counteraction by infiltrated B cells and hence possible humoral immune response in situ.

Perfusion ct based thrombolysis in acute ischaemic stroke

Background Despite use in clinical practice and trials of thrombolysis, a non-contrast CT is not sensitive for identifying penumbral tissue in acute stroke. This study evaluated how it compares with physiological imaging using CT perfusion.Methods 40 imaging datasets with non-contrast CT (NCCT) and perfusion CT (CTP) were retrospectively identified. 2 sets of observers (n¼6) and a neuroradiologist made a blind evaluation of the images. Inter-observer agreement was calculated for identifying ischaemic change on NCCT, and abnormalities on cerebral blood flow, time to peak and cerebral blood volume maps. A prospective cohort of 73 patients with anterior circulation cortical strokes were thrombolysed based on qualitative assessment of penumbral tissue on CTP within 3 h of stroke onset. Functional outcome was assessed at 3 months.Results Inter-rater agreement was moderate (k¼0.54) for early ischaemic change on NCCT. Perfusion maps improved this to substantial for deficit in cerebral blood volume (k¼0.67) and almost perfect for time to peak and cerebral blood flow (both k¼0.87). In the prospective arm, 58.9% of patients with cortical strokes were thrombolysed. There was no significant difference in attainment of complete recovery (p¼0.184) between the thrombolysed and nonthrombolysed group.Conclusions We demonstrate how perfusion CT aids clinical decision- making in acute stroke. Good functional outcomes from thrombolysis can be safely achieved using this physiologically informed approach.

Acute inflammatory response in the stomach of BALB/c mice challenged with coccoidal Helicobacter pylori

An experimental murine model was used to verify the viability and pathogenicity of coccoid Helicobacter pylori. For this purpose, 27 BALB/c mice were inoculated intragastrically with 1 ml broth culture (10(8)organisms/ml) of a coccoid H. pylori clinical isolate. The animals were divided into two groups. Nine were infected on a one-time basis (GA1) and 18 were infected on two consecutive days (GA2). Other 27 mice were inoculated with Brucella broth and divided in the same way; they composed the control group. Mice were killed at 2, 3, 7, 14 and 21 days post inoculation (pi). Fragments of stomach and duodenum were collected, fixed with 12% formalin and stained by hematoxilin-eosin and Giemsa for histopathological examination. Until the 14th()day, only reinfected mice had mild-to-moderate inflammatory infiltrate in the stomach. The infiltration was predominantly lymphomonocytic, although plasma cells and eosinophils could be seen. However, at 21st day, severe eosinophilic infiltration was present in the lamina propria and submucosa of gastric corpus. In subgroup GA1, animals presented lymphomonocytic infiltration in the stomach from 14th()day pi. Our results showed that coccoid H. pylori was able to induce an acute inflammatory response in stomach of reinfected mice since the initial periods of infection.

Assessment of the capacity to consent to treatment in patients admitted to acute medical wards

RAPPORT DE SYNTHÈSE : Introduction: L'évaluation de la capacité de discernement est importante d'un point de vue légal et éthique dans l'activité médicale quotidienne. Dans cette étude, nous avons évalué attentivement la capacité de discernement chez les patients admis dans un service médical aigu en utilisant l'évaluation du personnel médical, le score spécifique de Silberfeld, le MMSE ainsi que l'évaluation du psychiatre. Méthode : Pendant 3 mois, 195 patients admis dans un service de médecine interne d'un hôpital universitaire ont été inclus et leur capacité de discernement a été évaluée durant les premières 72 heures d'admission. Résultats : Sur les 195 patients, 38 furent incapables de discernement manifestement (patients inconscients ou avec des déficits cognitifs sévères) et 14 furent considérés incapables de discernement par le psychiatre (prévalence de l'incapacité de discernement de 26.7%). La corrélation entre l'évaluation du psychiatre et le questionnaire de Silberfeld fut faible (sensibilité 35.7%, spécificité 91.6%). Les cliniciens expérimentés montrèrent une plus haute corrélation (sensibilité 57.1 %, spécificité 96.5%). L'avis partagé par l'assistant, par le chef de clinique et l'infirmière se révéla le meilleur indicateur de l'évaluation psychiatrique (sensibilité 78.6%, spécificité 94.3%). Conclusion : La prévalence de l'incapacité de discernement chez les patients admis dans un service de médecine interne est élevée. Alors que le questionnaire de Silberfeld et le MMSE ne sont pas indiqués pour évaluer la capacité de discernement dans cette étude, l'évaluation par une équipe médicale multidisciplinaire reflète le mieux l'évaluation du psychiatre.

Establishment of HEV RNA reverse transcriptase PCR assays for the diagnosis of acute and chronic hepatitis E

Background and aim: H epatitis E v irus (HEV) infection has emerged as a c ause o f travel-related a nd autochthonous a cute hepatitis as well as chronic hepatitis in immunosuppressed patients. While t ravel-related cases a re c aused primarily b y infections w ith HEV of g enotype 1 ( HEV-1), autochthonous c ases a nd chronic cases a re d ue t o genotype 3 (HEV-3), which is s hared between humans and diverse animal species. The aim of this study was to establish HEV RNA detection assays f or q uantitative v iral load testing and genotyping. Methods: V iral RNA was p urified from plasma or s erum a nd converted to cDNA prior to (1) multiplex real-time PCR for HEV RNA quantification and (2) multiplex PCR coupled to DNA sequencing for HEV genotype determination. Real-time PCR was d esigned to match a ll known HEV genotypes available i n Genbank while PCR was designed using conserved primers flanking a variable region of the HEV RNA. Results: In a validation panel, the newly developed assays allowed for the reliable detection and genotyping of HEV-1 or HEV-3. Cases of t ravel-related and a utochthonous a cute h epatitis E a s well a s chronic hepatitis E i n immunosuppressed patients have b een identified using t hese a ssays a nd will be p resented in detail. Anti- HEV antibodies were n egative i n three well-characterized patients with chronic hepatitis E after organ transplantation. Conclusions: We developed and validated a quantitative HEV RNA detection assay that c an now be o ffered on a r outine basis (www.chuv.ch/imul/imu-collaborations-viral_hepatitis). Genotyping can also be offered on selected cases. HEV RNA detection is key in diagnosing chronic hepatitis E i n immunosuppressed patients with unexplained transaminase elevations, as serology can be negative in these patients.
