The diagnostic value in coeliac disease of circulating antibodies to casein, crude gliadin, and alpha gliadin was assessed using an adaption of the enzyme linked immunosorbent assay system. alpha Gliadin was the only antigen which consistently separated 26 patients with untreated coeliac disease from 26 normal controls and 13 patients with chronic inflammatory bowel disease. The mean assay inde...
1197 The mechanism for the air in the mediastinum is suggested as being due to rupture of marginal pulmonary alveoli, allowing the development of pulmonary interstitial emphysema. This then tracks through the fascial planes at the lung hilum, and from there into the mediasti-num and neck. There was no obvious underlying lung disease in our patient, and no further investigations were indicated. ...
Serological markers, combined with spatial analysis, offer a comparatively more sensitive means by which to measure and detect foci of malaria transmission in highland areas than traditional malariometric indicators. Plasmodium falciparum parasite prevalence, seroprevalence, and seroconversion rate to P. falciparum merozoite surface protein-119 (MSP-119) were measured in a cross-sectional surve...
African swine fever (ASF) is an infectious and economically important disease of domestic pigs. The absence of vaccine renders the diagnostic test the only tool that can be used for the control of new outbreaks of the disease. At present, the enzyme-linked immunosorbent assay (ELISA) test is the most useful method for large-scale ASF serological studies, although false positives have been detec...
BACKGROUND Interpretation of serological assays in Lyme borreliosis requires an understanding of the clinical indications and the limitations of the currently available tests. We therefore systematically reviewed the accuracy of serological tests for the diagnosis of Lyme borreliosis in Europe. METHODS We searched EMBASE en MEDLINE and contacted experts. Studies evaluating the diagnostic accu...
Analysis of serum from a patient with cutaneous leukocytoclastic vasculitis showed a mixed cryoglobulin with a monoclonal IgM kappa-antiglobulin component (6.5 mg/ml), strong rheumatoid factor activity (latex titre 1/5000), and positive serological tests for syphilis (fluorescent treponemal antibody-absorbed and Treponema pallidum haemagglutination assay). After removal of antiglobulin activity...
A test for farmer's lung is described employing the indirect fluorescent antibody technique. The test compared very favourably with standard precipitin tests, detecting 88% of a series of positive cases, as opposed to 38% detected by a precipitin test. The fluorescent antibody test, in addition, introduced some measure of quantitation of the serological response in the disease.
To assess the value of serological tests in diagnosing and monitoring the response to treatment of syphilis in patients infected with the human immunodeficiency virus (HIV), case notes of eight homosexual men with a history of treated syphilis, positive reactions to serological tests for syphilis, and documented subsequent conversion to HIV seropositivity were studied. No change was noted in se...
INTRODUCTION Rapid syphilis screening could facilitate case-identification in populations at high risk for sexually transmitted infections (STI). The aim of this study was to compare the performance and the cost-effectiveness of a rapid immunochromatography syphilis test with a traditional ELISA screening test in patients with suspected infectious syphilis or patients at high risk for STI/syphi...
Caprine arthritis encephalitis (CAE) is a chronic disease caused by a small ruminant lentivirus (SRLV), which causes significant losses in goat breeding. The actual state of animal infection with SRLV is difficult to determine due to a complex pathogenesis of the virus, including factors such as delayed or intermittent seroconversion in serological tests. Several serological techniques are avai...
