Treatment of systemic lupus erythematosus: new therapeutic options

Systemic lupus erythematosus (SLE) is a systemic autoimmune inflammatory disease of unknown cause, with heterogeneity in its clinical presentation, as well as variability in its clinical course and prognosis. The current goal of treatment is to achieve disease remission or a state of low activity, and thereby improve the patient's quality of life. Biological therapy in lupus, unlike other entities, although it has not been fully established, in recent years it has burst onto the scene with important therapeutic novelties. This review aims to update the therapeutic tools for the treatment of SLE focusing on the new molecules that have achieved the objectives of their clinical trials.

Baseline characteristics of systemic lupus erythematosus patients included in the Lupus Italian Registry of the Italian Society for Rheumatology

OBJECTIVE

To report baseline data of SLE patients enrolled in the Lupus Italian Registry (LIRE).

METHODS

Patients affected by SLE aged ≥ 16 years were consecutively recruited in a multicenter prospective study comparing two cohorts: patients starting biologic immunosuppressants (BC) and patients starting non-biologic immunosuppresants (NBC).

RESULTS

308 patients were enrolled, 179 in NBC and 129 in BC. Mean age at disease onset and at diagnosis was significantly higher in NBC (p = 0.023, p = 0.045, respectively). Disease duration was longer in BC (p = 0.022). Patients in BC presented arthritis more frequently (p = 0.024), those in NBC nephropathy (p = 0.03). Quality of life was worse in BC (p = 0.031). Anti-dsDNA, low C3, were significantly more frequent in BC (p < 0.001, p = 0.009, respectively). Mycophenolate, methotrexate and azathioprine were the drugs more frequently prescribed in NBC, Belimumab and Rituximab in BC.

CONCLUSION

The predominant organ involvement was different in the two cohorts: kidney involvement predominated in NBC, joint involvement in BC. Despite the younger age at disease onset, patients of the BC had a longer disease duration and more frequently had taken a cumulative prednisone dosage greater than 10 g. Even the pattern of clinical manifestations inducing to prescribe biological rather than conventional immunosuppressants was quite different.Keywords: Autoantibody(ies), autoimmune disease, belimumab, cohort studies, glucocorticoids, immunosuppressants, rituximab, systemic lupus erythematosus.
