Optimizing Patient Care: A Systematic Review of Multidisciplinary Approaches for SLE Management

Systemic lupus erythematosus (SLE) is characterized by multisystemic clinical manifestations ranging from a relatively mild involvement to potentially life-threatening complications. Due to this complexity, a multidisciplinary (MD) approach is the best strategy for optimizing patients' care. The main aim of this systematic literature review (SLR) was to scrutinize the published data regarding the MD approach for the management of SLE patients. The secondary objective was to evaluate the outcomes of the MD approach in SLE patients. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines were used. We performed an SLR to retrieve articles available in English or Italian listed in PubMed, Embase, Cinahl, and Cochrane Library concerning the MD approach used in observational studies and clinical trials. Four independent reviewers performed the study selection and data collection. Of 5451 abstracts evaluated, 19 studies were included in the SLR. The MD approach was most frequently described in the context of SLE pregnancy, reported in 10 papers. MD teams were composed of a rheumatologist, except for one cohort study; a gynecologist; a psychologist; a nurse; and other health professionals. MD approaches had a positive impact on pregnancy-related complications and disease flares and improved SLE psychological impact. Although international recommendations advise an MD approach for managing SLE, our review highlighted the paucity of data supporting this strategy, with most of the available evidence on the management of SLE during pregnancy

CXCL-13 serum levels in patients with rheumatoid arthritis treated with abatacept

Objectives: C-X-C motif chemokine 13 (CXCL-13), which is expressed by synovial follicular dendritic cells and activated mature antigen-experienced T-helper cells, has been described as a surrogate marker of lymphoid phenotype of synovitis in rheumatoid arthritis (RA). A preferential response to anti-interleukin-6 receptor (IL-6R) as compared to anti-tumour necrosis factor alpha (TNFα) monotherapy has been described in patients with increased levels of CXCL-13. We hypothesised that serum levels of CXCL-13 could be used as a biomarker of response to treatment with abatacept (ABA), a T-cell co-stimulation blocker. Methods: Serum levels of CXCL-13 and of soluble intracellular adhesion molecule 1 (sICAM-1) (a putative marker of the myeloid subtype of synovitis) were measured by indirect solid-phase enzyme immunoassays, before (T0) and after 6 months of therapy with ABA (T6) in 63 patients with RA. Circulating T follicular helper cells and B cell subpopulations were identified by flow-cytometry. Results: At T0, CXCL-13 serum levels were higher in RA patients than in healthy controls (p=0.0001) and correlated with disease activity, while no difference between the two groups was observed as far as sICAM-1 levels. Serum levels of CXCL-13 levels decreased after therapy with ABA both in patients who achieved a clinical response (p<0.01) and in non-responders (p=0.01), whereas sICAM-1 levels did not significantly change. When comparing RA patients who responded to ABA with non-responders no significant difference of baseline serum levels of CXCL-13 was observed. Conclusions: CXCL-13 serum levels are raised in RA patients and decrease after therapy with ABA. We were not able to demonstrate that serum CXCL-13 levels predict the clinical response to ABA in RA patients
