Serological and Urinary Biomarkers in Latin American Patients With Systemic Lupus Erythematosus: GLADEL 2.0 Cohort
Lupus nephritis (LN) is one of the main manifestationsin SLE patients, having an important impact on morbidity and mortality. Renal biopsy is the "gold standard" for the diagnosis of LN, however, it is an invasive technique, not free of complications,which is not recommended to be performed serially as a follow-up tool for patients with LN. Searching for biomarkers in SLE has been the subject of interesting research, although results have not always been relevant. Multiple biomarkers have been studied in different locations (soluble markers in blood, urine and biological fluids),of different nature(autoantibodies, genetic markers of "kidney damage") looking atdiagnostic and/orprognostic features. In recent years, several biomarkers have been developed that seek to find an association with pathological patterns, with pathogenic mechanisms and with a non-invasive diagnosis of different glomerulopathies, allowing the identification of prognostic subgroups in each type of kidney disease, while predicting response to treatment and/or recurrence. To date, double-stranded anti-DNA antibodies (anti-dsDNA) and serum complement are the only non-invasive routine biomarkers for monitoring renal activity in patients with LN. However, these markers are only the reflection of the immune activity of the disease and they are not markers of renal damage or poor prognosis. For all the above, the purpose of this study is, in a case-control study, to evaluate simultaneously serum (ANA, anti-dsDNA, anti-C1q, anti-cardiolipin IgG and IgM, anti-ß2GPI IgG and IgM, anti-phosphatidylserine/prothrombin antibodies, and anti-DFS70 antibodies) and urinary biomarkers, and the presence of anti-DFS70 antibodies, in a multiethnic cohort of patients with SLE such as the cohort of GLADEL, and assess its possible correlation with various socio-demographic, clinical and serological manifestations of the disease.
In subgroup of patients, transcriptome studies will be performed using RNA from blood and tissue to identify possible transcriptional signatures.

Sampling Method
Study Population
Each center will include 25 patients with SLE divided into four groups, each with their corresponding healthy control (ratio 1:1).
Group 1.Patients with SLE, without renal involvement (never), of any time of disease duration. Total: 10 patients.
Group 2.Patients with SLE, with prevalent renal involvement (at any time of evolution), currently inactive (*): Total: 5 patients.
Group 3.Patients with SLE,with prevalent renal involvement (atany time of evolution), currently active (*). Total: 5 patients.
Group 4.Patients with SLE,with incident renal involvementof recent onset (maximum 3 months), without immunosuppressive treatment and with renal biopsy (mandatory criterion). Total: 5 patients.
Description
Inclusion Criteria:
- Consecutive patients with a diagnosis of SLE will be included. Patients should meet at least one ofthe classification criteria: ACR 1982/1997 (1) and/or SLICC 2012 (2) to determine the efficacy of calcineurin inhibitor-containing treatment regimens in LN cohorts by ethnic groups.
- Age ≥18 years old.
- Patients and controls that volunteer toparticipate and sign the informed consent
Exclusion Criteria:
- Patients with other systemic autoimmune diseases or overlap syndrome (rheumatoid arthritis, systemic sclerosis, dermatomyositis, systemic vasculitis and others).
- Patients who have urinary infection, pregnancy or have a history of hepatitis B, C or HIV virus infection.
- Those patients presenting with antiphospholipid syndrome (APS) associated with lupus will not be excluded from the study.
