O-11 Proposal for extending the role Of ABMSPS in reporting cervical loops

CYTOPATHOLOGY, Issue 2007
K. Ellis
Introduction:, The advanced biomedical scientist practitioner (ABMSP) in Cervical Cytology was established in the NHS cervical screening programme (NHSCCSP) in 2001 and there are approximately 60 ABMSPs in post. The aim of this study was to explore the potential for further expansion of their role in the NHSCSP by reporting the histology of loop excision biopsies of the cervical transformation zone (LLETZ). Methods:, The initial study included LLETZ specimens from 55 sequential patients, which, according to standard local practice had the diagnosis of CIN confirmed by cervical punch biopsy prior to the procedure. All the cases were independently examined by an ABMSP and a consultant histopathologist and reports complying with the Royal College of pathologists (RCPath) minimum data sets were assembled. The cases were reviewed at the discussion microscope and ABMSP reports were compared to the final reports issued by the histopathologist. Results:, In the preliminary findings, total agreement between ABMSP and consultant histopathologist was reached on just under 90% of cases. Of those cases that did not reach total agreement, none varied by more than one grade. There was agreement on other parameters from the RCPath minimum data sets. Discussion:, Based on our preliminary findings, it appears there may be scope for extending the role of ABMSPs to report LLETZ samples under the supervision of a histopathologist. We plan to increase the number of cases both in our department and through collaboration with other UK centres and to present evidence to the RCPath, with a view to adoption of this role by ABMSPs and development of an appropriate training scheme.

A multicenter survey of rituximab therapy for refractory antineutrophil cytoplasmic antibody,associated vasculitis

ARTHRITIS & RHEUMATISM, Issue 7 2009

Objective B cell depletion with rituximab has allowed remissions in relapsing or refractory antineutrophil cytoplasmic antibody (ANCA),associated vasculitis in small studies. The aim of this study was to determine the efficacy and safety of rituximab for ANCA-associated vasculitis in a larger multicenter cohort. This permitted comparison of rituximab dosing regimens, the value of continuing immunosuppression, and investigation of ANCA and B cell levels as re-treatment biomarkers. Methods Retrospective, standardized data collection from 65 sequential patients receiving rituximab for refractory ANCA-associated vasculitis at 4 centers in the UK was used. Results All patients achieved B cell depletion. Complete remission occurred in 49 of the 65 patients (75%), partial remission in 15 (23%), and no response in 1 (2%). The prednisolone dosage was reduced from 12.5 mg/day (median) to 9.0 mg/day at 6 months (P = 0.0006). Immunosuppressive therapy was withdrawn in 37 of 60 patients (62%). Twenty-eight of 49 patients who achieved full remission (57%) experienced relapse (median 11.5 months). B cell return preceded relapse in 14 of 27 patients (52%). Although ANCA levels fell after rituximab therapy, relapse was not associated with ANCA positivity or a rise in ANCA levels. Neither the initial rituximab regimen (4 infusions of 375 mg/m2 each given 1 week apart or 2 infusions of 1 gm each given 2 weeks apart) nor withdrawal of immunosuppressive therapy (37 of 60 patients [62%]) influenced the timing of relapse. Thirty-eight patients received ,2 courses of rituximab, and complete remission was induced or maintained in 32 of them (84%). IgM levels fell, although IgG levels remained stable. Forty-six serious adverse events occurred, including 2 episodes of late-onset neutropenia, which were attributed to rituximab. Conclusion Rituximab was effective remission induction therapy for refractory ANCA-associated vasculitis in this study. There was no difference in efficacy between the 2 main treatment regimens. Continuing immunosuppression did not reduce relapses. Relapses occurred, but re-treatment was effective and safe. There was no clear influence of rituximab on the frequency of serious adverse events. ANCA and B cell levels lacked sufficient sensitivity to guide the timing of re-treatment. [source]


Acute Ethanol Coingestion Confers a Lower Risk of Hepatotoxicity after Deliberate Acetaminophen Overdose

ACADEMIC EMERGENCY MEDICINE, Issue 1 2008
W. Stephen Waring PhD
Abstract Objectives:, Little is known about the clinical significance of acute ethanol coingestion around the time of acetaminophen (paracetamol) overdose. This study prospectively examined the effect of acute ethanol coingestion on risk of hepatotoxicity among patients admitted to hospital for N -acetylcysteine (NAC) therapy after deliberate acetaminophen overdose. Methods:, This was a prospective observational study and included sequential patients who presented within 24 hours of acute acetaminophen ingestion and required NAC therapy. Significant hepatotoxicity was defined by alanine transaminase > 1,000 U/L or the international normalized ratio > 1.3 after a standardized intravenous administration of 300 mg/kg NAC. Results:, There were 362 patients, including 178 (49.2%) who coingested ethanol acutely. The prevalence of hepatotoxicity was 5.1% (95% CI = 2.6% to 9.5%) in those who ingested ethanol, compared to 15.2% (95% CI = 10.7% to 21.2%) in those who did not (p = 0.0027 by chi-square proportional test). Acute ethanol intake conferred a lower risk of hepatotoxicity in patients who had acetaminophen concentrations above or below the "200-line" and was independent of the interval between ingestion and assessment. Conclusions:, Acute ethanol intake is associated with a lower risk of hepatotoxicity after acetaminophen overdose. This apparent protective effect cannot be explained solely by lower exposure to acetaminophen in this group, nor differences in the interval between ingestion and initiation of treatment. Further work is required to establish mechanisms by which ethanol might confer protection against hepatotoxicity, so as to identify novel strategies for reducing risk after acute acetaminophen ingestion.

Dyslipidemia in patients with angiographically confirmed coronary artery disease,an opportunity for improvement

CLINICAL CARDIOLOGY, Issue 10 2004

Abstract Background: There are few data about lipid profiles in unselected patients with angiographically confirmed coronary artery disease (CAD). Hypothesis: The study was undertaken to investigate the demographics, clinical characteristics, angiographic findings, and baseline lipid status of 1,000 consecutive unselected patients with angiographically confirmed CAD. Methods: Between April 2001 and July 2002, we obtained informed consent and prospectively collected clinical characteristics, fasting lipid profiles, and angiographic results from 1,000 sequential patients with CAD confirmed by angiography. Results: In these patients with confirmed CAD, 78% had history of hyperlipidemia. Although 62% were receiving lip-id-lowering therapy, only 46% had a low-density lipoprotein target of < 100 mg/dl, and only 20% had achieved all four National Cholesterol Education Program-recommended lip-id targets. Conclusions: Better strategies to ensure optimal lipid levels are required. One such method using computerized workflow is being evaluated in this population. [source]
