Abstract: Methods and reagents for diagnosing, prognosing, and treating systemic lupus erythematosus (SLE) are disclosed, involving calculating an SLE risk score for a subject based on a level of each of an erythrocyte C4d (EC4d) marker, a B-cell C4d (BC4d) marker, antinuclear antibodies (ANA), anti-Smith antibodies (anti-Sm) and optional rule-out markers (SS-B/La, Scl-70, Jo-1, CENP, MCV).
Abstract: The present invention provides methods and reagents for diagnosing system lupus erythematosus and for monitoring system lupus erythematosus disease activity in a subject.
Abstract: The present invention provides compositions and their use in predicting anti-tumor necrosis factor therapy response in a patient with an inflammatory disease.
Abstract: The present invention provides compositions and their use in diagnosing and/or distinguishing inflammatory bowel disease and irritable bowel syndrome.

Abstract: Pharmacogenetic methods for determining a predicting responsiveness to antifolate therapy for subjects that present with recent-onset undifferentiated arthritis. The methods are based on the determination of a set of clinical parameter values and determining a predicted responsiveness to antifolate therapy by correlating the parameter values with predefined responsiveness values associated with ranges of parameter values. Parameters values that are decisive for responsiveness to antifolate therapy may include polymorphisms in the methylenetetrahydrofolate dehydrogenase (MTHFD1) gene as well as in three genes involved in the adenosine release pathway, the presence or absence of Rheumatoid factors, gender, pre- or postmenopausal status and/or smoking status.

Abstract: The present invention provides a method for efficiently converting methotrexate polyglutamates to methotrexate in a cellular extract by contacting the cellular extract with gamma glutamyl hydrolase under conditions suitable for efficient conversion of methotrexate polyglutamates to methotrexate.
Abstract: The present invention provides methods of diagnosing and monitoring systemic lupus erythematosus by measuring cell-based complement activation products (CB-CAPS) in a subject's blood. In particular, the invention describes a diagnostic method employing the measurement of multiple complement activation products on the surfaces of red blood cells, white blood cells, and platelets (e.g., EC4d, BC4d, PC4d, and ECR1). A diagnostic algorithm utilizing the determined levels of CB-CAPS is also disclosed.
