OBJECTIVE A simple and rapid immunological assay method has been developed to demonstrate the presence of IgG antibodies to 30Kd protein antigen (30Kdpa) and culture filtrate protein (CFP) in the CSF of patients with Tuberculous meningitis (TBM). METHOD Antibody capturing Enzyme Linked Immunosorbent Assay (ELISA) was standardized with CFP antigen of MTB. The IgG antibodies were assayed in CSF...

Tuberculous meningitis (TBM) is a frequent cause of meningitis in individuals with human immunodeficiency virus (HIV) infection, resulting in death in approximately 40% of affected patients. A severe complication of antiretroviral therapy (ART) in these patients is neurological tuberculosis-immune reconstitution inflammatory syndrome (IRIS), but its underlying cause remains poorly understood. T...

BACKGROUND Early diagnosis of tuberculous meningitis (TBM) is still a challenge; the present study aimed to establish a method of detecting the antigen early secreted antigenic target 6 (ESAT-6) in cerebrospinal fluid (CSF) by an indirect enzyme-linked immunosorbance assay (ELISA) protocol and to study the value of detecting ESAT-6 in CSF in the early diagnosis of TBM. METHODS An indirect ELI...

Experimental anti-tubular basement membrane (anti-TBM) disease is an autoimmune interstitial nephritis elicited in susceptible rodents after immunization with renal tubular antigen. The nephritogenic antigen in the immunizing preparation is 3M-1, a 48,000 Mr noncollagenous glycoprotein. The hallmarks of the renal lesion are the presence of anti-TBM antibodies (anti-TBM-Ab) and a dense mononucle...

Tuberculous meningitis (TBM) is a severe infection of the central nervous system, particularly in developing countries. Prompt diagnosis and treatment are necessary to decrease the high rates of disability and death associated with TBM. The diagnosis is often time and labour intensive; thus, a simple, accurate and rapid diagnostic test is needed. The adenosine deaminase (ADA) activity test is a...

Model selection is a necessary step in many practical regression analyses. But for methods based on estimating equations, such as the quasi-likelihood and generalized estimating equation (GEE) approaches, there seem to be few well-studied model selection techniques. In this article, we propose a new model selection criterion that minimizes the expected predictive bias (EPB) of estimating equati...

This study is to investigate the association between Leukotriene A4 hydrolase (LTA4H) single nucleotide polymorphisms and susceptibility to tuberculous meningitis (TBM) in Chinese Han population of Northern China, and its association with clinical treatment. Patients with TBM and healthy controls were enrolled. We investigated the gene polymorphism (rs17525495) of LTA4H and tuberculous meningit...

OBJECTIVE To compare the differences in presentation and outcome of patients with tuberculous meningitis (TBM) and cryptococcal meningitis (CCM). STUDY DESIGN Case series. PLACE AND DURATION OF STUDY The Aga Khan University Hospital, Karachi, from December 1995 to December 2005. METHODOLOGY Patients with a confirmed diagnosis of TBM or CCM were included in this study. The signs and sympto...

Using monoclonal antibody affinity chromatography, we isolated a 48,000 mol wt, glucose-rich glycoprotein (3M-1) from collagenase-solubilized rabbit renal tubular basement membrane (SRTA). The purified 3M-1 protein is noncollagenous, and is capable of inducing anti-TBM (tubular basement membrane) antibodies and interstitial nephritis in susceptible hosts. Further, when SRTA, at a normally nephr...
