The C3dg Fragment of Complement Is Superior to Conventional C3 as a Diagnostic Biomarker in Systemic Lupus Erythematosus
نویسندگان
چکیده
Method: We included SLE patients (n = 169) and controls (n = 170) and developed a modified C3dg assay where C3dg fragments were separated from the large plasma proteins by polyethylene glycol (PEG), and the supernatant containing the C3dg fragment was used for analysis in an antibody-based sandwich-type assay. Gel permeation chromatography and western blotting were used to establish the optimal conditions for PEG precipitation.

A review on the latest clinical and laboratory criteria for clinical diagnosis of Systemic Lupus Erythematosus
Systemic Lupus Erythematosus (SLE) is a complex autoimmune disease with various organs involvement which early diagnosis of disease is critical for successful treatment. The subjects with the possibility of SLE who visit by physician, their full medical history and specific immunological tests should investigate precisely in order to subsequently asses their hematological and renal parameters t...
متن کاملUse of serum or buffer-changed EDTA-plasma in a rapid, inexpensive, and easy-to-perform hemolytic complement assay for differential diagnosis of systemic lupus erythematosus and monitoring of patients with the disease.
We previously described a simplified quantitative hemolytic assay for classical pathway (CP) hemolytic function in serum that has been shown to correlate with the 50% hemolytic complement (CH50) assay. In the present study, we used this assay to compare CP functions; plasma levels of C3, C4, and C3dg; and ratios of C3dg to C3 in healthy individuals and patients with systemic lupus erythematosus...

Objective(s)Lupus nephritis (LN) is frequently associated with a poor long-term prognosis. Renal biopsy is the diagnostic method of choice in this condition. Urine biomarkers have been mentioned in the diagnosis of LN. The study,s purpose was to evaluate the performance of urinary monocyte chemoattractant protein 1(UMCP-1) as a biomarker of renal involvement in systemic lupus erythematosus.Mate...

Objective(s): lupus nephritis (LN) is a severe form of systemic lupus erythematosus (SLE) with renal complications. Current diagnosis is based on invasive renal biopsy and serum antibodies and complement levels that are not specific enough. The current study aims to identify new biomarker candidates for non-invasive diagnosis of LN and explore the pathogenic mechanisms...
متن کاملThree cases of systemic lupus erythematosus and review of the mechanisms concerning treatment with intravenous immunoglobulins (IVIG).
The systemic lupus erythematosus (SLE) is an autoimmune disorder with a broad array of clinical signs. In this research, we aimed to use intravenous immunoglobulins (IVIG) called intacglobin as monotherapy to manage an SLE in three patients. Laboratory investigations for SLE diagnosis were done, including the detection of anti-nuclear antibodies (ANA) and SLE confirmation by detecting high tite...
