Background: The treatment of Lupus Nephritis (LN) is an unmet need in the management of patients with Systemic Lupus Erythematosus (SLE). CASE PRESENTATION : We report two cases of women affected by Lupus Nephritis (LN) ISN/RNP Class IV with serological active disease, high disease activity and marked fatigue. In both cases, Mycophenolate mofetil (MMF), as induction therapy, was poorly tolerated because of gastrointestinal toxicity. Belimumab, together with low-doses of MMF, was effective as induction treatment leading to early achievement of complete renal response in these two selected cases of LN.
Conclusions: We also report a literature review concerning the efficacy and safety of Belimumab in Lupus Nephritis. Further studies are needed to evaluate the use of Belimumab to manage the renal involvement in patients with Systemic Lupus Erythematosus, waiting for the results of ongoing randomized clinical trials.

The complement system plays a paradoxical role in systemic lupus erythematosus physiopathology, acting both as a protective mechanism and as a driver of tissue injury, depending on disease stage. Neutrophil extracellular traps (NETs) further exacerbate disease activity by promoting complement activation and autoantigen exposure, forming an amplifying inflammatory loop. Lupus nephritis remains challenging to monitor using conventional complement biomarkers such as CH50, C3, and C4; the utility of anti-C1q, anti-ficolin, and anti-C1s antibodies, along with tissue-based markers such as renal C4d and C5b-9 deposits, as markers of disease activity and prognosis, is discussed.

Introduction: Systemic lupus erythematosus (SLE) is a heterogeneous autoimmune disorder characterized by multi-organ involvement and variable clinical manifestations. Recurrent clinical patterns suggest distinct phenotypes, where cluster analysis of autoantibodies could identify prognostic subtypes.
Objectives: To define and describe serological clusters and their clinical-epidemiological characteristics, as well as their association with comorbidities, disease activity measures, severity, and damage.

Protein tyrosine phosphatase nonreceptor type 22 (PTPN22) is encoded by a gene strongly associated with lupus and other autoimmune diseases. PTPN22 regulates T cell receptor (TCR) signaling through dephosphorylation of the kinases lymphocyte-specific protein tyrosine kinase (LCK) and zeta-chain-associated protein kinase 70 (ZAP70). The regulation of PTPN22 remains poorly understood.

Toll-like receptor 7 (TLR7) is an endosomal sensor that responds to both pathogen-derived and self-derived single-stranded RNA (ssRNA). Responses of TLR7 to self-derived ssRNA have been implicated in the development of autoimmune diseases, such as systemic lupus erythematosus (SLE). TLR7 antagonists and inhibitory anti-TLR7 monoclonal antibodies (mAbs) can protect lupus-prone NZBWF1 mice from lethal nephritis.
