Remission Status (remission + status)
Selected AbstractsSerum C-Reactive Protein Concentration as an Indicator of Remission Status in Dogs with Multicentric LymphomaJOURNAL OF VETERINARY INTERNAL MEDICINE, Issue 6 2007Lise Nielsen Background: The acute-phase protein C-reactive protein (CRP) is used as a diagnostic and prognostic marker in humans with various neoplasias, including non-Hodgkin's lymphoma. Objective: To evaluate if CRP could be used to detect different remission states in dogs with lymphoma. Animals: Twenty-two dogs with untreated multicentric lymphoma. Methods: Prospective observational study. Blood samples were collected at the time of diagnosis, before each chemotherapy session, and at follow-up visits, resulting in 287 serum samples. Results: Before therapy, a statistically significant majority of the dogs (P= .0019) had CRP concentrations above the reference range (68%, 15/22). After achieving complete remission 90% (18/20) of the dogs had CRP concentrations within the reference range, and the difference in values before and after treatment was statistically significant (P < .001). CRP concentrations of dogs in complete remission (median, 1.91; range, 0.2,103) were significantly different (P= .031) from those of dogs with partial remission (median, 2.48; range, 0,89), stable disease (median, 1.77; range, 1.03,42.65), or progressive disease (median, 8.7; range, 0,82.5). There was profound variation of CRP measurements within each dog. Conclusions: CRP is useful in determining complete remission status after treatment with cytotoxic drugs. However, the individual variation between dogs means CRP concentration is not sufficiently different in other remission states to permit its use in monitoring progression of the disease. Greater reliability in determining remission status might be achieved by combining CRP concentration with other serum markers. [source] Exploring the idiotypes of insulin antibodies as markers for remission in Type 1 diabetesDIABETIC MEDICINE, Issue 12 2004D. Devendra Abstract Aims Complete or partial remission can occur in newly diagnosed Type 1 diabetes patients. We created idiotype-specific reagents to explore the idiotypes of insulin antibodies (IA) in a patient in remission, and to compare with a patient who was not. Methods Phage display was used to create a library of phagotopes specific to insulin binding in four sera. Sera from a Type 1 diabetes subject deemed to have undergone remission were taken at diagnosis and again during remission. Sera from a non-remitter were taken at diagnosis and after 3 months on insulin. Phagotopes from the four sera were randomly selected and tested for insulin specificity in a radiobinding assay by using sera from remitters and non-remitters. Results IA-binding phagotope selected from serum during remission displaced insulin binding in all nine IA+ remitters and all 10 IA+ non-remitters. IA-binding phagotope selected from the non-remission patient (3 months after insulin therapy) displaced insulin binding in 8/9 IA+ remitters and 8/10 IA+ non-remitters. The consensus peptide sequences adduced from the phages were identical for both these phagotopes. Phagotopes derived from insulin autoantibody-positive individuals at diagnosis were unable to displace insulin binding in the IA+ sera 3 months later, whether in remission or not. Conclusions We have established the principle of using phage display in the investigation of insulin antibodies during remission in Type 1 diabetes. The immunological characteristics of IA 3 months after the introduction of insulin treatment were different from those at diagnosis of Type 1 diabetes (IAA). Using phage display technology, it was not possible to distinguish insulin antibodies according to remission status. [source] Usefulness of MRI volumetric evaluation in patients with squamous cell cancer of the head and neck treated with neoadjuvant chemotherapyHEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 2 2007Mehran Baghi MD Abstract Background. The purpose was to evaluate the efficacy of tumor volumetry on MRI as predictive of response to treatment with induction chemotherapy, comparing the results with endoscopy. Methods: Fifty patients with advanced squamous cell carcinoma of the head and neck (SSCHN) who underwent MRI volumetry before and after neoadjuvant chemotherapy consisting of docetaxel, cisplatin, and 5-fluorouracil (TPF) were included in this study. The tumor volume was calculated by a slice-by-slice evaluation. With the standard software of a workstation, the area of the tumor was measured slice by slice using manual segmentation. To evaluate the efficacy of MRI volumetry, pretreatment volume was compared with pretreatment remission status as evaluated with endoscopy. Results. Forty-five (90%) patients demonstrated a tumor downstaging after chemotherapy. Fourteen (28%) patients showed a complete histologic remission (CR), 31 (62%) patients showed a partial remission (PR). Pretreatment tumor volume was significantly different between patients whose tumor completely responded (CR) and those whose tumor did not completely respond or whose disease was stable or was progressive (p = .00023). We defined a threshold for the pretreatment tumor volume in patients with CR, which was equal to 29.71 cc. Conclusion. We propose that MRI tumor volume analyses can be a useful parameter to predict the response to neoadjuvant chemotherapy in SCCHN. © 2006 Wiley Periodicals, Inc.

[source] Transcription of proteinase 3 and related myelopoiesis genes in peripheral blood mononuclear cells of patients with active Wegener's granulomatosisARTHRITIS & RHEUMATISM, Issue 6 2010Chris Cheadle Objective Wegener's granulomatosis (WG) is a systemic inflammatory disease that is associated with substantial morbidity. The aim of this study was to understand the biology underlying WG and to discover markers of disease activity that would be useful for prognosis and treatment guidance. Methods Gene expression profiling was performed using total RNA from peripheral blood mononuclear cells (PBMCs) and granulocyte fractions from 41 patients with WG and 23 healthy control subjects. Gene set enrichment analysis (GSEA) was performed to search for candidate WG-associated molecular pathways and disease activity biomarkers. Principal components analysis was used to visualize relationships between subgroups of WG patients and controls. Longitudinal changes in proteinase 3 (PR3) gene expression were evaluated using reverse transcription,polymerase chain reaction, and clinical outcomes, including remission status and disease activity, were determined using the Birmingham Vasculitis Activity Score for WG (BVAS-WG). Results Eighty-six genes in WG PBMCs and 40 in WG polymorphonuclear neutrophils (PMNs) were significantly up-regulated relative to controls. Genes up-regulated in WG PBMCs were involved in myeloid differentiation, and these included the WG autoantigen PR3. The coordinated regulation of myeloid differentiation genes was confirmed by GSEA. The median expression values of the 86 up-regulated genes in WG PBMCs were associated with disease activity (P = 1.3 × 10,4), and WG patients with low-level expression of the WG signature genes showed expression profiles that were only modestly different from that in healthy controls (P = 0.07). PR3 transcription was significantly up-regulated in WG PBMCs (P = 1.3 × 10,5, false discovery rate [FDR] 0.002), but not in WG PMNs (P = 0.03, FDR 0.28), and a preliminary longitudinal analysis showed that the fold change in PR3 RNA levels in WG PBMCs corresponded to changes in the BVAS-WG score over time. Conclusion Transcription of PR3 and related myeloid differentiation genes in PBMCs may represent novel markers of disease activity in WG.

Occupational status and social adjustment six months after hospitalization early in the course of bipolar disorder: a prospective study. Bipolar Disord 2010: 12: 10,20. © 2010 The Authors. Journal compilation © 2010 John Wiley & Sons A/S. Objectives:, Bipolar disorder is often accompanied by poor functional outcomes, the determinants of which are not fully understood. We assessed patients with bipolar disorder undergoing a hospital admission early in the illness course and identified predictors of occupational status, overall social adjustment, and work adjustment six months later. Methods:, This was a prospective longitudinal cohort study. During hospitalization patients were evaluated with a cognitive battery; symptoms, occupational history, and other clinical factors were also assessed. At six-month follow-up, patients' symptom remission status was assessed; they were also evaluated as to their occupational status, overall social adjustment, and work adjustment. Multivariate analyses were used to identify predictors of these outcomes. Results:, Among the 52 participants, the average rating of overall social adjustment at follow-up was between mild and moderate maladjustment. While 51 had a history of working full time, only 28 (54%) worked full time at follow-up. A total of 24 (46%) had symptoms that met criteria for a full depression or mania syndrome. In multivariate analyses, full-time occupational status at follow-up was predicted by the absence of baseline substance abuse. Better overall social adjustment was predicted by better performance on cognitive tasks of processing speed and by symptom remission; the latter variable also predicted work adjustment. Conclusions:, Persons with bipolar disorder have limited occupational recovery and overall social adjustment six months after a hospital admission early in the illness course. Predictors vary among outcomes; performance on tasks of processing speed and the extent of symptom remission are independently associated with functional outcomes. [source] | ||||||||||
